Dear Shareholder:
 
     In October 1998, we agreed to be acquired by Sunrise Assisted Living, Inc.
We have called the special meeting for you to consider and vote on the merger
agreement, as amended in March 1999.
 
     In the merger, you will receive 0.3333 of a share of Sunrise common stock
for each Karrington common share owned by you, other than shares for which you
exercise dissenters' rights. The value of the Sunrise common stock you will
receive in the merger will depend on the market price of Sunrise common stock at
the time of the merger. Sunrise common stock is traded on the National Market
tier of the Nasdaq Stock Market under the symbol "SNRZ." On April    , 1999,
Sunrise common stock closed at $      per share.
 
     YOUR BOARD OF DIRECTORS BELIEVES THE MERGER IS FAIR TO YOU AND IN YOUR BEST
INTERESTS AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR ADOPTION OF THE AMENDED
MERGER AGREEMENT AND APPROVAL OF THE MERGER.
 
   
     We describe the amended merger agreement and the merger in detail in the
enclosed proxy statement/prospectus. Please give it your prompt and careful
attention. YOU SHOULD ALSO CAREFULLY CONSIDER THE RISK FACTORS RELATING TO THE
MERGER THAT WE DESCRIBE STARTING ON PAGE 16 OF THE PROXY STATEMENT/PROSPECTUS.
    
 
     YOUR VOTE IS IMPORTANT. For the merger to occur, the holders of at least
two-thirds of the outstanding Karrington common shares must vote to adopt the
amended merger agreement and approve the merger. Therefore, even if you plan to
attend the special meeting, please complete, date, and sign the enclosed proxy
and mail it promptly in the postage-paid envelope provided.
 
                                          Very truly yours,
 
                                          Richard R. Slager
                                          Chief Executive Officer

                      WHAT YOU WILL RECEIVE IN THE MERGER
 
     In the merger, each Karrington common share you own, except for shares for
which you exercise dissenters' rights, will be converted into the right to
receive 0.3333 of a share of Sunrise common stock, plus the right attached to
Sunrise common stock to purchase shares of series C junior participating
preferred stock of Sunrise under its stockholder rights plan. Thus, you will
receive in the merger for your Karrington common shares a number of shares of
Sunrise common stock determined by multiplying the number of Karrington common
shares you own times the exchange ratio of 0.3333. Cash will be paid instead of
issuing fractional shares of Sunrise. The actual value of the shares of Sunrise
common stock you will receive in the merger will depend on the market price of
Sunrise common stock at the time of the merger. On April      , 1999, the
closing price of Sunrise common stock on the National Market tier of the Nasdaq
Stock Market was $         per share.

THE COMPANIES
 
SUNRISE ASSISTED LIVING, INC.
9401 Lee Highway, Suite 300
Fairfax, VA 22031
(703) 273-7500
 
      Sunrise provides assisted living services to the elderly. In general,
assisted living represents a combination of housing and 24-hour a day personal
support services designed to aid elderly residents with activities of daily
living, such as bathing, eating, personal hygiene, grooming and dressing.
Additional levels of assistance are provided to residents with low acuity
medical needs, to incontinent residents and to residents with Alzheimer's
disease or other forms of dementia.
 
      The following table sets forth information with respect to Sunrise
assisted living facilities operated and in development at December 31, 1998:

      Of the 100 facilities open or under construction, 75 are 100% owned, 14
are owned by entities in which Sunrise has ownership interests ranging from 9%
to 70% and 11 are managed by Sunrise for third parties. Of the 48 development
sites under contract, Sunrise has entered into contracts to purchase 46
development sites and to lease two others under long-term ground leases. Sunrise
has received zoning approval from the applicable municipal authority to
construct an assisted living facility on nine sites and is pursuing zoning
approval on the remaining sites. Three of the open facilities are subject to
long-term ground leases. Sunrise also manages three skilled nursing facilities
for a third party. Unlike assisted living facilities, skilled nursing facilities
provide 24 hour skilled nursing care, supervised by a registered nurse.
 
KARRINGTON HEALTH, INC.

KARRINGTON'S REASONS FOR THE MERGER AND RECOMMENDATION OF KARRINGTON BOARD (SEE
PAGE 36)
 
      Your board of directors believes that the merger is fair to you and in
your best interests and unanimously recommends that you vote "FOR" the proposal
to adopt the amended merger agreement and approve the merger. Our reasons for
the merger and the basis for the recommendations of your board of directors
include:
 
      - the relative business, financial condition, operations, earnings and
        prospects of Sunrise and Karrington;
 
      - industry and economic factors, including consideration of:
 
         - trends toward consolidation;
 
         - the greater access to capital available to larger companies; and
 
         - the competitive and financial challenges facing Karrington if it were
           not acquired by Sunrise.
 
      - based on the closing price of Sunrise common stock on October 16, 1998,
        the last trading day immediately before the public announcement of the
        merger agreement, each Karrington common share would have been converted
        into Sunrise common stock having a value of $12.00. This represented a
        32.4% premium over the $9.06 closing price of Karrington common shares
        on October 16, 1998; and
 
   
      - the opinion of BT Alex. Brown Incorporated as to the fairness, from a
        financial point of view, of the exchange ratio to the holders of
        Karrington common shares. The full text of BT Alex. Brown's written
        opinion, dated March 4, 1999, the date on which the Karrington board
        approved the terms of the amendment to the merger agreement, is attached
        as Appendix C and should be read carefully in its entirety. THE OPINION
        OF BT ALEX. BROWN IS DIRECTED TO THE KARRINGTON BOARD AND DOES NOT
        CONSTITUTE A RECOMMENDATION TO ANY SHAREHOLDER AS TO HOW A SHAREHOLDER
        SHOULD VOTE AT THE KARRINGTON SPECIAL MEETING. The aggregate fee payable
        by Karrington to BT Alex. Brown in connection with the merger is $2.85
        million.

SUNRISE'S REASONS FOR THE MERGER (SEE PAGE 39)
 
      Sunrise's reasons for the merger include:
 
      - the merger will allow Sunrise to expand rapidly into complementary
        markets in the midwestern and eastern United States in which there is
        little geographic overlap with existing Sunrise facilities;
 
      - the merger will allow Sunrise to increase its development pipeline from
        71 facilities with a resident capacity of approximately 6,030 units to
        89 facilities with a resident capacity in excess of 7,300 units; and
 
      - the merger will allow Sunrise to combine its superior ability to access
        capital with Karrington's development activities.
 
      Sunrise intends to sell 17 Karrington facilities within 12 months
following the merger. Most of the Karrington facilities Sunrise intends to sell
are Karrington Cottage prototype models, which consist of 20 or less units.
These facilities are located in smaller midwestern markets where cost savings
from clustering of facilities generally is not possible due to the size of the
markets. By comparison, the Sunrise prototype model consists of approximately 75
units and typically is located in a major metropolitan or suburban market where
efficiencies can be achieved by clustering facilities. Please refer to
"Properties" on page 82 for additional information regarding the Karrington
facilities Sunrise intends to sell following the merger.
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER (SEE PAGE 51)

      We expect the merger to be tax-free. We describe the material U.S. federal
income tax consequences of the merger in more detail on page 51. The tax
consequences to you will depend on the facts of your own situation. Please
consult with your tax advisor for a full understanding of the tax consequences
to you of the merger.
 
RIGHTS OF DISSENTING SHAREHOLDERS
(SEE PAGE 54)
 
      If you object to the merger, Ohio law permits you to seek relief as a
dissenting shareholder and have the "fair cash value" of your Karrington common
shares determined by a court and paid to you in cash. To do this, you must
satisfy each of the following conditions:
 
      - you must be a Karrington shareholder on the record date for the vote on
        the merger;
 
      - you must not vote dissenting shares in favor of the merger;
 
      - you must deliver to us a written demand for the fair cash value of the
        shares for which you exercise dissenters' rights within 10 days after
        the vote on the merger;
 
      - if we request, you must deliver to us the certificates evidencing the
        Karrington shares for which you exercise dissenters' rights for
        endorsement of a legend that demand for their fair cash value has been
        made; and
 
      - within three months after your delivery to us of your written demand for
        payment of the fair cash value of the shares for which
 
                                        3
<PAGE>   13
 
you exercise dissenters' rights, you must file or join in a petition in the
Court of Common Pleas of Franklin County, Ohio for a determination of their fair
cash value unless you and we have agreed on their fair cash value.
 
You will not receive any stock in Sunrise if you dissent and follow all of the
required procedures. Instead, you will only receive the fair cash value of your
Karrington common shares for which you exercise dissenters' rights.
 
      For more information about the steps to be taken by Karrington
shareholders who wish to exercise their dissenters' rights, see "The
Merger -- Rights of Dissenting Shareholders" on page 54. The relevant section of
Ohio law governing this process is attached to this document as Appendix D.
 
THE MERGER (SEE PAGE 34)
 
AMENDED MERGER AGREEMENT (SEE PAGE 59)
 
      We have attached the merger agreement and amendment no. 1 to the merger
agreement, both of which are legal documents that govern the merger, as
Appendices A and B. We encourage you to carefully read these documents.
 
   
      Sunrise also filed or incorporated by reference other related agreements
as exhibits to Sunrise's registration statement. Please see the section titled
"Where You Can Find More Information," on page 112, for instructions on how to
obtain copies of these exhibits.
    
 
EXCHANGE RATIO (SEE PAGE 59)
 
      Unless you exercise dissenters' rights, your Karrington common shares will
be converted in the merger into the right to receive 0.3333 of a share of
Sunrise common stock for each Karrington common share owned by you. In addition,
each share of Sunrise common stock will have attached to it the right to
purchase shares of series C junior participating preferred stock of Sunrise
under its stockholder rights plan. Cash will be paid instead of fractional
shares.
 
      Sunrise common stock is traded on the National Market tier of the Nasdaq
Stock Market under the symbol "SNRZ." You can obtain current stock price quotes
from most newspapers and other financial sources.
 
EXCHANGE OF SHARES (SEE PAGE 60)
 
      Promptly after the merger, Sunrise or its exchange agent will send you a
letter of transmittal with instructions for exchanging your Karrington common
share certificates for stock certificates representing Sunrise common stock
issued to you in the merger and any cash to which you are entitled instead of
fractional shares.
 
CONDITIONS (SEE PAGE 65)
 
      Before we can complete the merger, a number of conditions must be
satisfied. These include:
 
      - adoption of the amended merger agreement and approval of the merger by
        the Karrington shareholders;
 
      - the absence of any court order or law having the effect of making
        illegal or otherwise prohibiting the closing of the merger;
 
      - receipt of all required third party consents;
 
      - exercise of dissenters' rights by holders of not more than 10% of
 
                                        4
<PAGE>   14
 
the outstanding Karrington common shares;
 
      - delivery of: (A) new option agreements evidencing the consent of all of
        the holders of Karrington stock options to have their options assumed by
        Sunrise or (B) an opinion from counsel to Karrington that the option
        holders' consent is not required under the terms of the Karrington stock
        option plan; and
 
      - other customary closing conditions.
 
      Where the law permits, Sunrise or Karrington could decide to complete the
merger even though one or more conditions was not satisfied. By law, neither
Sunrise nor Karrington can waive (A) the condition of Karrington shareholder
approval of the amended merger agreement and the merger or (B) any court order
or law having the effect of making illegal or otherwise prohibiting the closing
of the merger. Whether any of the other conditions would be waived would depend
upon the facts and circumstances as determined by the reasonable business
judgment of the board of directors of Sunrise or Karrington. If Sunrise or
Karrington waived compliance with one or more of the conditions and the
condition was deemed material to the vote of Karrington shareholders, Karrington
would have to resolicit the approval of its shareholders before closing the
merger.
 
TERMINATION (SEE PAGE 67)
 
      Either Sunrise or Karrington may terminate the amended merger agreement
if:
 
      - the merger is not completed by June 30, 1999, which date may be extended
        until September 30, 1999 if necessary to obtain third party consents;
 
      - a final and nonappealable order is issued enjoining or prohibiting the
        merger; or
 
      - Karrington shareholders do not approve the amended merger agreement and
        the merger.
 
      Sunrise may terminate the amended merger agreement if:
 
      - Karrington's board of directors withdraws or changes its recommendation
        that Karrington shareholders approve the amended merger agreement and
        the merger;
 
      - following the announcement of a competing acquisition proposal by a
        third party, Karrington fails to hold the special meeting; or
 
      - Karrington materially breaches any of its representations and warranties
        or fails to materially comply with its obligations.
 
      Karrington may terminate the amended merger agreement if:
 
      - Sunrise materially breaches any of its representations and warranties or
        fails to materially comply with its obligations.
 
      Sunrise and Karrington also may mutually agree to terminate the amended
merger agreement.
 
TERMINATION FEE (SEE PAGE 68)
 
      Karrington must pay Sunrise a termination fee of $5.0 million if:
 
      - Either Sunrise or Karrington terminates the amended merger agreement
        because (A) the merger is not completed by
 
                                        5
<PAGE>   15
 
        June 30, 1999, or by September 30, 1999, if extended, or (B) Karrington
        shareholders do not approve the amended merger agreement and the merger,
        provided that before termination of the amended merger agreement a
        competing acquisition proposal is announced or received by Karrington
        and the competing transaction is completed within one-year after
        termination of the amended merger agreement.
 
      - Sunrise terminates the amended merger agreement, following announcement
        or receipt by Karrington of a competing acquisition proposal, because
        (A) your board of directors withdraws or changes its recommendation that
        you approve the amended merger agreement and the merger or (B)
        Karrington does not hold the special meeting, provided that the
        competing transaction is completed within one-year after termination of
        the amended merger agreement.
 
OPTION AGREEMENT (SEE PAGE 69)
 
      Karrington has granted Sunrise an option to purchase up to 9.9% of the
outstanding Karrington common shares at an exercise price of $9.00 per share.
The option would become exercisable by Sunrise if a competing acquisition
proposal is announced or received by Karrington. If a competing transaction is
consummated, Karrington may become obligated to repurchase the option from
Sunrise at a repurchase price of up to $5.0 million. The option agreement may
discourage other companies from proposing or trying to combine with Karrington
before we complete the merger.
AMENDMENT (SEE PAGE 68)
 
      Karrington and Sunrise may mutually agree to further amend the amended
merger agreement. However, the amended merger agreement may not be further
amended under Ohio law after you approve the merger if the amendment reduces or
changes the consideration that you would receive in the merger unless you
approve the amendment.
 
ACCOUNTING TREATMENT (SEE PAGE 51)
 
      The merger will be treated as a purchase for financial accounting
purposes.
 
REGULATORY MATTERS (SEE PAGE 51)
 
      Sunrise, Karrington and JMAC, Inc., Karrington's largest shareholder, have
made pre-merger filings with U.S. antitrust authorities under the Hart-Scott-
Rodino Antitrust Improvements Act. On December 8, 1998, the Antitrust Division
of the U.S. Department of Justice and the Federal Trade Commission granted early
termination of the waiting period under the Act.
 
CONFLICTS OF INTEREST OF KARRINGTON'S DIRECTORS AND OFFICERS IN THE MERGER
(SEE PAGE 48)
 
      Some of Karrington's directors and officers have interests in the merger
that may conflict with your interests as a shareholder of Karrington. These
include:
 
      - in connection with the merger, Richard R. Slager, Karrington's chairman
        and chief executive officer, and Pete A. Klisares, Karrington's
        president, entered into new employment agreements with Karrington for a
        term of six months following the closing of the
 
                                        6
<PAGE>   16
 
        merger. The new employment agreements provide benefits to Mr. Slager and
        Mr. Klisares of approximately $722,000 and $257,000, respectively, in
        consideration for their future services and, in the case of Mr. Slager,
        an agreement not to compete with Karrington.
 
      - Mr. Klisares previously was granted an option for 30,000 shares at an
        exercise price of $9.00 per share. Of these options, options for 7,500
        shares are presently exercisable and the remaining options for 22,500
        unvested shares will vest upon the closing of the merger.
 
      - the amended merger agreement requires that Sunrise:
 
         - indemnify Karrington's directors and officers for events occurring
           before the merger;
 
         - keep in effect Karrington's current directors' and officers'
           liability insurance for six years following the merger; and
 
         - appoint Mr. Slager following the merger as the representative of
           JMAC, Inc., to fill a newly created vacancy on Sunrise's board of
           directors. As long as JMAC, Inc. continues to beneficially own at
           least 500,000 shares of Sunrise common stock, Sunrise has agreed to
           re-nominate Mr. Slager, or another nominee of JMAC, Inc. reasonably
           acceptable to Sunrise's board of directors, and solicit proxies for
           his re-election as a director of Sunrise.
 
      Your board of directors knew about these interests, and considered them,
when it approved the amended merger agreement and the merger.
 
REQUIRED VOTE (SEE PAGE 31)
 
      The affirmative vote of the holders of at least two-thirds of the
outstanding Karrington common shares is required to adopt the amended merger
agreement and approve the merger.
 
SHAREHOLDER AGREEMENTS (SEE PAGE 31)
 
      Each of Karrington's directors and executive officers and JMAC, Inc. has
entered into shareholder agreements, as amended, with Sunrise under which they
have granted Sunrise an irrevocable proxy to vote all of their Karrington common
shares in favor of the amended merger agreement and the merger and against any
competing third party transaction. The directors and executive officers of
Karrington and JMAC, Inc. own a total of 3,038,068 Karrington common shares,
representing approximately 44.4% of the outstanding Karrington common shares.
Accordingly, of the 3,801,300 remaining outstanding Karrington common shares
held by nonaffiliates, only 40.0%, or 1,521,511 shares, must be voted in favor
of the amended merger agreement and the merger to satisfy the two-thirds vote
requirement to adopt the amended merger agreement and approve the merger.

DIFFERENCES IN THE RIGHTS OF SHAREHOLDERS (SEE PAGE 98)
    
 
   
      Your rights as a Karrington shareholder are currently governed by the Ohio
General Corporation Law and the articles of incorporation and code of
regulations of Karrington. Upon completion of the merger, you will become a
stockholder of Sunrise, and your rights will be governed by the Delaware General
Corporation Law and the amended and restated certificate of incorporation and
bylaws of Sunrise. See "Comparison of Shareholder Rights" on page 98 for
additional information.

- -------------------------
(1) Earnings before interest expense, taxes, depreciation and amortization is
    presented because Sunrise believes this data is used by some investors to
    evaluate Sunrise's ability to meet debt service requirements. Sunrise
    considers earnings before interest, taxes, depreciation and amortization to
    be an indicative measure of its operating performance due to the
    significance of Sunrise's long-lived assets and because this data can be
    used to measure Sunrise's ability to service debt, fund capital expenditures
    and expand its business. However, this data should not be considered as an
    alternative to net income, operating profit, cash flows from operations or
    any other operating or liquidity performance measure prescribed by generally
    accepted accounting principles. In addition, earnings before interest,
    taxes, depreciation and amortization as calculated by Sunrise may not be
    comparable to similarly titled measures reported by other companies.
    Interest expense, taxes, depreciation and amortization, which are not
    reflected in the presentation of earnings before interest, taxes,
    depreciation and amortization, have been, and will be, incurred by Sunrise.
    Investors are cautioned that these excluded items are significant components
    in understanding and assessing Sunrise's financial performance.
 
(2) Based on monthly occupancy for owned facilities, opened or operated for at
    least 12 months, or that have achieved occupancy percentages of 95% or
    above. The occupancy rate excludes facilities with temporary vacancies and
    resident relocations generally of between three to six months due to
    renovations.

UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
 
   
     The following unaudited selected pro forma financial information combines
Sunrise's historical results with Karrington's historical results for the year
ended December 31, 1998. The unaudited pro forma condensed combined statements
of operations information gives effect to the merger as if it had occurred on
January 1, 1998. The unaudited pro forma condensed combined balance sheet
information gives effect to the merger as if it occurred on December 31, 1998.
This information should be read in conjunction with the unaudited pro forma
financial information included in this proxy statement/ prospectus starting on

COMPARATIVE PER SHARE DATA
 
   
     The following table sets forth, at and for the periods indicated, book
value and net income (loss) per share data for Sunrise common stock and
Karrington common shares on a historical basis, for Sunrise on a combined pro
forma basis and for Karrington on a pro form equivalent basis. The pro forma
equivalent per share data are computed by multiplying the pro forma combined
amounts by the exchange ratio of 0.3333 to 1. The market price per equivalent
common share of Karrington included in the following table was computed by
multiplying the market price per share of Sunrise common stock on October 16,
1998 by the exchange ratio of 0.3333 to 1. The pro forma data are not indicative
of the results of future operations or the results that would have occurred had
the merger been consummated at the beginning of the periods presented. The
information set forth below should be read in conjunction with the financial
statements and related notes of Sunrise and Karrington included or incorporated

                      RISK FACTORS RELATING TO THE MERGER
 
     In considering whether to adopt the amended merger agreement and approve
the merger, you should consider carefully all of the information set forth or
incorporated by reference in this proxy statement/prospectus, including the risk
factors listed below.
 
YOU WILL RECEIVE 0.3333 OF A SHARE OF SUNRISE COMMON STOCK FOR EACH KARRINGTON
COMMON SHARE YOU OWN DESPITE CHANGES IN MARKET VALUE OF KARRINGTON COMMON SHARES
OR SUNRISE COMMON STOCK
 
     Each Karrington common share will be exchanged for 0.3333 of a share of
Sunrise common stock in the merger. There will be no adjustment for changes in
the market price of either Sunrise common stock or Karrington common shares.
Accordingly, the market value of Sunrise common stock you receive in the merger
will depend on the market value of Sunrise common stock at the time of
completion of the merger.
 
FLUCTUATIONS IN SUNRISE'S COMMON STOCK PRICE WILL AFFECT THE VALUE OF THE
CONSIDERATION YOU RECEIVE IN THE MERGER
 
     Fluctuations in the market price of Sunrise common stock will affect the
value of the Sunrise common stock you receive in the merger. The market price
per share of Sunrise common stock at the time the merger is completed may vary
significantly from the date Sunrise and Karrington signed the merger agreement,
the date of this proxy statement/prospectus or the date of the special meeting.
Because of market fluctuations, there can be no assurance that the market price
per share of Sunrise common stock at the time of the merger will equal or exceed
the market price of Sunrise common stock at the date of the special meeting.
 
SUNRISE MAY NOT BE ABLE TO SUCCESSFULLY INTEGRATE KARRINGTON INTO ITS OPERATIONS
 
     The integration of Karrington into Sunrise's operations will require
substantial attention from management. The diversion of management attention to
the integration of Karrington's operations into Sunrise and any difficulties
encountered in the transition and integration processes could have an adverse
effect on the revenues, expenses and operating results of Sunrise following the
merger.
 
ANY DELAYS EXPERIENCED IN DEVELOPING NEW FACILITIES COULD ADVERSELY AFFECT
SUNRISE'S REVENUES AND RESULTS OF OPERATIONS FOLLOWING THE MERGER
 
     The growth objectives of both Sunrise and Karrington include the
development of a significant number of new assisted living facilities. Sunrise
currently has 23 facilities under construction with a resident capacity of
2,160. Sunrise also has entered into contracts to purchase 46 additional
development sites and to lease two others under long-term ground leases. Of
these sites, Sunrise has received zoning approval from the applicable municipal
authority to construct an assisted living facility on nine sites and is pursuing
zoning approval on the remaining sites. Karrington currently has an additional
10 facilities under construction with a resident capacity of 624. Karrington
also has an additional eight development sites under contract. Karrington has
received zoning
 
                                       16
<PAGE>   26
 
approval to construct an assisted living facility on six of these eight
development sites. In the ordinary course of their respective businesses,
Sunrise and Karrington each evaluate new sites and opportunities for further
growth on an ongoing basis.
 
     The ability of Sunrise to achieve these development plans following the
merger will depend upon a variety of factors, many of which are outside the
control of Sunrise. These factors include:
 
     - obtaining zoning, land use, building, occupancy, licensing and other
       required governmental permits for the construction of new facilities
       without experiencing significant delays;
 
     - completing construction of new facilities on budget and on schedule;
 
     - the ability to work with third-party contractors and subcontractors who
       construct the facilities;
 
     - shortages of labor or materials that could delay projects or make them
       more expensive;
 
     - adverse weather conditions that could delay projects;
 
     - finding suitable sites for future development activities at acceptable
       prices; and
 
     - addressing changes in laws and regulations or how existing laws and
       regulations are applied.
 
     We cannot assure you that we will not experience delays in completing
facilities under construction or in development or that we will be able to
identify suitable sites at acceptable prices for future development activities.
If we fail following the merger to achieve the combined company's development
plans, our growth could slow, which would adversely impact our revenues and
results of operations.
 
SUNRISE WILL NEED ADDITIONAL FINANCING TO FUND DEVELOPMENT ACTIVITIES
 
     Following the merger, Sunrise will need to obtain additional financial
resources to fund its and Karrington's development and construction activities.
Sunrise and Karrington estimate that it will cost between $463.0 million and
$697.0 million to complete the 59 facilities the two companies currently have
under development. Sunrise expects that cash flow from combined company
operations, together with borrowings under existing credit facilities, will be
sufficient to fund the needs of the combined entity for at least six months
following the merger. Sunrise expects from time to time to seek additional
funding through public or private financing sources, including equity or debt
financing. If it raises additional capital by selling shares of Sunrise common
stock, then the shares of Sunrise common stock you will receive in the merger
may be diluted. If Sunrise is not able to obtain additional financing on
favorable terms, it may have to delay or eliminate all or some of its or
Karrington's development projects, which could adversely affect the combined
entity's revenues and results of operations.
 
                                       17
<PAGE>   27
 
SUNRISE'S FAILURE TO GENERATE SUFFICIENT CASH FLOW TO COVER REQUIRED INTEREST,
PRINCIPAL AND OPERATING LEASE PAYMENTS COULD RESULT IN DEFAULTS OF THE RELATED
DEBT OR OPERATING LEASES
 
     At December 31, 1998, Sunrise had mortgage, construction and other
indebtedness totaling $428.3 million. Unused lines of credit were $175.0 million
at that date. On a pro forma basis giving effect to the merger, Sunrise would
have had mortgage, construction and other indebtedness totaling $502.4 million
and unused lines of credit of $175.0 million at December 31, 1998. Sunrise
intends to continue financing its and Karrington's properties through mortgage
financing and possibly operating leases or other types of financing, including
lines of credit. Sunrise expects the amount of mortgage indebtedness and other
debt and debt related payments to increase substantially following the merger as
the combined entity pursues its growth strategy. As a result, an increasing
portion of cash flow will be devoted to debt service and related payments. There
can be no assurance that Sunrise will generate sufficient cash flow from
operations following the merger to cover required interest, principal and
operating lease payments. Any payment or other default could cause the lender to
foreclose upon the facilities securing the indebtedness or, in the case of an
operating lease, could terminate the lease, with a consequent loss of income and
asset value to Sunrise. In some cases, the indebtedness is secured by the
facility and a pledge of Sunrise's interests in the facility. In the event of a
default, the lender could avoid judicial procedures required to foreclose on
real property by foreclosing on the pledge instead, thus accelerating the
lender's acquisition of the facility. Further, because several of Sunrise's
mortgages contain cross-default and cross-collateralization provisions, a
payment or other default by it could affect a significant number of properties.
 
SUNRISE'S FAILURE TO COMPLY WITH FINANCIAL COVENANTS CONTAINED IN DEBT
INSTRUMENTS COULD RESULT IN THE ACCELERATION OF THE RELATED DEBT
 
     There are various financial covenants and other restrictions in Sunrise's
debt instruments, including provisions which:
 
     - require it to meet specified financial tests. For example, Sunrise's
       $86.3 million multi-property mortgage, which is secured by 15 of its 77
       facilities, requires that these facilities maintain a cash flow to
       interest expense coverage ratio of at least 1.25 to 1. Sunrise's $250
       million credit facility requires Sunrise to have a consolidated tangible
       net worth of at least $178 million and to maintain a consolidated minimum
       cash liquidity balance of at least $25 million. These tests are
       administered on a monthly or quarterly basis, depending on the covenant;
 
     - require consent for changes in management or control of Sunrise. For
       example, Sunrise's $250 million revolving credit facility requires the
       lender's consent for any merger where Paul Klaassen or Teresa Klaassen
       does not remain chairman of the board and chief executive officer of
       Sunrise;
 
     - restrict the ability of Sunrise subsidiaries to borrow additional funds,
       dispose of assets or engage in mergers or other business combinations
       without lender consent; and
 
                                       18
<PAGE>   28
 
     - require that Sunrise maintain minimum occupancy levels at its facilities.
       For example, Sunrise's $250 million credit facility requires that 85%
       occupancy be achieved after 12 months for a newly opened facility and,
       following this 12-month period, be maintained at or above that level.
 
     If Sunrise fails to comply with any of these requirements, then the related
indebtedness could become due and payable prior to its stated due date. There
can be no assurance that Sunrise could pay this debt if it became due.
 
INTEREST RATE INCREASES COULD ADVERSELY AFFECT EARNINGS DUE TO FLOATING-RATE
DEBT
 
     At December 31, 1998, Sunrise had approximately $169.0 million of
floating-rate debt. On a pro forma basis giving effect to the merger, it would
have had approximately $224.9 million of floating-rate debt at that date. Debt
incurred in the future also may bear interest at floating rates. Therefore,
increases in prevailing interest rates could increase Sunrise's interest payment
obligations which would negatively impact earnings. For example, a one-eighth of
one percent increase in interest rates would increase annual interest expense by
approximately $281,164 based on the amount of pro forma floating-rate debt at
December 31, 1998.
 
SUNRISE MAY NOT HAVE SUFFICIENT RESOURCES TO REPURCHASE ITS 5 1/2% CONVERTIBLE
SUBORDINATED NOTES DUE 2002 IF THE NOTES ARE TENDERED TO SUNRISE UPON A CHANGE
IN CONTROL
 
     In June 1997, Sunrise issued and sold $150 million aggregate principal
amount of 5 1/2% convertible subordinated notes due 2002. These notes are
convertible, at the option of the holder, into shares of Sunrise common stock at
a conversion rate of $37.1875 per share, or 26.89 shares per $1,000 principal
amount of the notes. The conversion rate is subject to customary anti-dilution
adjustments. The notes rank junior in payment to substantially all indebtedness
of Sunrise existing at the time of the issuance of the notes and subsequently
incurred by it. If a change of control of Sunrise were to occur, each holder of
a convertible note can require Sunrise to repurchase all or a portion of the
notes owned by the holder. Under the convertible notes, a change in control of
Sunrise includes:
 
      - any acquisition by a person or entity of more than 50% of the voting
        power of Sunrise's outstanding voting stock; or
 
      - the acquisition by merger of Sunrise if, following the merger Sunrise
        stockholders own less than 50% of voting power of the resulting entity's
        voting securities, unless Sunrise's common stock is trading at least
        equal to 105% of the conversion price in effect at the time of the
        acquisition by merger or at least 90% of the consideration in the
        acquisition by merger consists of listed stock.
 
     Following a change in control, we cannot assure you that Sunrise would have
sufficient financial resources, or would be able to arrange financing, to pay
the repurchase price of all convertible notes tendered by noteholders. Any
failure by Sunrise to purchase tendered convertible notes upon any change of
control of Sunrise would constitute an event of default under the convertible
notes.

INCREASING COMPETITION IN THE ASSISTED LIVING INDUSTRY COULD ADVERSELY AFFECT
THE REVENUES OF THE COMBINED COMPANY
 
     The long-term care industry is highly competitive and the assisted living
segment is becoming increasingly competitive. Sunrise and Karrington compete
with numerous other companies that provide similar long-term care alternatives,
such as home health care agencies, facility-based service programs, retirement
communities, convalescent centers and other assisted living providers. Although
some competitors are significantly larger, there are no one or more dominant
companies in the assisted living segment. In a recent industry report, it is
estimated that there are approximately 770,000 total assisted living beds
currently available, and that the 25 largest owners of assisted living
properties, which includes Sunrise, has 180,446 or only 23% of those currently
available. The largest individual owner has only 3% of the total assisted living
beds currently available. In general, regulatory and other barriers to
competitive entry in the assisted living industry are not substantial. In
pursuing their growth strategies, both Sunrise and Karrington have experienced
and expect to continue to experience increased competition in their efforts to
develop and acquire assisted living facilities. Some of the present and
potential competitors of Sunrise and Karrington are significantly larger and
have, or may obtain, greater financial resources than Sunrise and Karrington,
even on a combined basis. Consequently, we cannot assure you that we will not
encounter increased competition that could limit our ability to attract
residents or expand our business following the merger, which could have a
material adverse effect on the revenues and earnings of the combined company.
 
SUNRISE AND KARRINGTON REVENUES BOTH DEPEND ON PRIVATE PAY SOURCES
 
     Assisted living services currently are not generally reimbursable under
government reimbursement programs, such as Medicare and Medicaid. Accordingly,
substantially all of Sunrise's and Karrington's resident fee revenues are
derived from private pay sources consisting of income or assets of residents or
their family members. In general, because of the expense associated with
building new facilities and the staffing and other costs of providing the
assisted living services at those facilities, only seniors with income or assets
meeting or exceeding the comparable median in the regions where Sunrise or
Karrington facilities are located can afford to pay the daily resident fees,
which currently range from $46 to $163 for Sunrise and $36 to $175 for
Karrington depending on the level of services provided.
 
IF DEVELOPMENT OF NEW ASSISTED LIVING FACILITIES OUTPACES DEMAND, THE COMBINED
COMPANY COULD EXPERIENCE LOWER OPERATING RESULTS
 
     Sunrise and Karrington believe that some assisted living markets have
become or are on the verge of becoming overbuilt. As described above, regulation
and other barriers to entry into the assisted living industry are not
substantial. Consequently, the development of new assisted living facilities
could outpace demand. Overbuilding in Sunrise and Karrington market areas could,
therefore, cause the combined company following the merger to experience
decreased occupancy, depressed margins or lower operating results.
 
                                       20
<PAGE>   30
 
AN UNEXPECTEDLY HIGH RESIDENT TURNOVER RATE COULD ADVERSELY AFFECT OUR REVENUES
AND EARNINGS
 
     State regulations governing assisted living facilities require written
resident agreements with each resident. These regulations also require that each
resident have the right to terminate the resident agreement for any reason on
reasonable notice. Consistent with these regulations, the resident agreements
signed by Sunrise and Karrington allow residents to terminate their agreement on
30 days' notice. Thus, neither Sunrise nor Karrington can contract with
residents to stay for longer periods of time, unlike typical apartment leasing
arrangements that involve lease agreements with specified leasing periods of up
to a year or longer. If a large number of residents elected to terminate their
resident agreements at or around the same time, then the combined entity's
business could be adversely affected. In addition, the advanced age of our
average residents means that the resident turnover rate in our assisted living
facilities may be less predictable. An unexpectedly high turnover rate could
have a material adverse effect on our respective businesses in the future.
 
SUNRISE MAY EXPERIENCE DIFFICULTY IN MANAGING ITS GROWTH
 
     Sunrise expects that the number of its owned and operated facilities will
increase substantially as it pursues its growth plans following the merger. This
intended rapid growth will place demands on its management resources. Its
ability to manage its growth effectively will require that it continue to expand
its operational, financial and management systems and that it continue to
attract, train, motivate, manage and retain key employees. If Sunrise is unable
to manage its growth effectively, its business and financial results could be
adversely affected.
 
SUNRISE'S BUSINESS AND FINANCIAL RESULTS DEPEND ON THE CONTINUED SERVICE OF ITS
KEY OFFICERS
 
     Sunrise depends on the services of Paul J. Klaassen, its chairman of the
board and chief executive officer and co-founder; Teresa M. Klaassen, its
executive vice president, secretary and co-founder; and David W. Faeder, its
president and chief financial officer. If Sunrise were to lose the services of
any of these individuals, its business and financial results could be adversely
affected. None of these individuals has an employment agreement with Sunrise.
 
COMPETITION FOR SKILLED PERSONNEL COULD INCREASE STAFFING AND LABOR COSTS
 
     Both Sunrise and Karrington compete with various health care services
providers, including other elderly care providers, in attracting and retaining
qualified and skilled personnel. A shortage of nurses or other trained personnel
or general inflationary pressures may require that we enhance our pay and
benefits package to compete effectively for such personnel. If there is an
increase in these costs or if the combined company fails to attract and retain
qualified and skilled personnel, the business and financial results of Sunrise
following the merger could be adversely affected.

THE NEED TO COMPLY WITH GOVERNMENT REGULATION OF ASSISTED LIVING FACILITIES MAY
INCREASE SUNRISE'S AND KARRINGTON'S COSTS OF DOING BUSINESS
 
     Assisted living facilities are subject to regulation and licensing by state
and local health and social service agencies and other regulatory authorities.
Although requirements vary from state to state, in general, these requirements
address:
 
     - personnel education, training, and records;
 
     - facility services, including;
 
       - administration of medication;
 
       - assistance with self-administration of medication; and
 
       - the provision of limited nursing services;
 
     - monitoring of resident wellness;
 
     - physical plant specifications;
 
     - furnishing of resident units;
 
     - food and housekeeping services;
 
     - emergency evacuation plans; and
 
     - resident rights and responsibilities, including in some states the right
       to receive health care services from providers of a resident's choice.
 
Some facilities also are licensed to provide independent living services, which
generally involve lower levels of resident assistance. In several of the states
in which Sunrise or Karrington operate or intend to operate, assisted living
facilities also require a certificate of need before the facility can be opened.
In most states, assisted living facilities also are subject to state or local
building code, fire code and food service licensing or certification
requirements. Like other health care facilities, assisted living facilities are
subject to periodic survey or inspection by governmental authorities.
 
     From time to time in the ordinary course of business, Sunrise and
Karrington receive deficiency reports, which they review to take appropriate
corrective action. Although most inspection deficiencies are resolved through a
plan of correction, the reviewing agency typically is authorized to take action
against a licensed facility where deficiencies are noted in the inspection
process. This action may include imposition of fines, imposition of a
provisional or conditional license or suspension or revocation of a license or
other sanctions. If either company fails to comply with applicable requirements,
the business and revenues of the combined company could be materially and
adversely affected. To date, none of the deficiency reports received by Sunrise
or Karrington has resulted in a suspension, fine or other disposition that has
had a material adverse effect on either Sunrise's or Karrington's revenues.
 
     Regulation of the assisted living industry is evolving. The combined
company's operations could suffer if future regulatory developments, such as
mandatory increases in scope and quality of care given to residents, are enacted
and licensing and certification
 
                                       22
<PAGE>   32
 
standards are revised. For example, if more states seek and obtain Medicare
waivers to authorize reimbursement for assisted living, the prospect of some
federal regulation may become more likely. If regulatory requirements increase,
the costs of complying with those requirements also could increase.
 
     Both Sunrise and Karrington also are subject to federal and state
anti-remuneration laws, such as the federal health care program anti-kickback
law, which governs various types of financial arrangements among health care
providers and others who may be in a position to refer or recommend patients to
these providers. This law prohibits direct and indirect payments that are
intended to induce the referral of patients to, the arranging of services by, or
the recommending of, a particular provider of health care items or services. The
federal health care program anti-kickback law has been interpreted to apply to
some contractual relationships between health care providers and sources of
patient referral. Similar state laws vary from state to state, are sometimes
vague and have rarely been interpreted by courts or regulatory agencies.
Violation of these laws can result in loss of licensure, civil or criminal
penalties, and exclusion of health care providers or suppliers from furnishing
covered items or services to beneficiaries of the federal health care program.
We cannot be sure that these laws will be interpreted consistently with our
practices.
 
THE DISCOVERY OF ENVIRONMENTAL PROBLEMS ON ANY OF THE PROPERTIES OWNED OR
OPERATED BY SUNRISE COULD RESULT IN SUBSTANTIAL COSTS TO SUNRISE
 
     Under various federal, state and local environmental laws, ordinances and
regulations, a current or previous owner or operator of real property may be
held liable for the costs of removal or remediation of hazardous or toxic
substances, including asbestos-containing materials, that could be located on,
in or under a property. These laws and regulations often impose liability
without regard to whether or not the owner or operator knew of, or was
responsible for, the presence or release of the hazardous or toxic substances.
The costs of any required remediation or removal of these substances could be
substantial. In addition, the liability of an owner or operator is generally not
limited and could exceed the property's value and the aggregate assets of the
owner or operator. An owner or operator or an entity that arranges for the
disposal of hazardous or toxic substances at a disposal site also may be liable
for the costs of any required remediation or removal of hazardous or toxic
substances.
 
     Sunrise engages consultants to conduct Phase I environmental studies of
development sites that are placed under contract. If the Phase I study indicates
the existence or the possibility of the existence of hazardous or toxic
substances on the property, a Phase II study is requested and performed. The
Phase I and Phase II studies, as applicable, may not reveal all environmental
liabilities. There could be, therefore, material environmental liabilities of
which Sunrise is unaware. In connection with the ownership or operation of its
properties, Sunrise could be liable for the costs of remediation or removal of
hazardous or toxic substances. Sunrise also could be liable for other costs,
including governmental fines and damages for injuries to persons or properties.
As a result, the presence, with or without Sunrise's knowledge, of hazardous
 
                                       23
<PAGE>   33
 
or toxic substances at any property owned or operated by it, or acquired or
operated by it in the future, could have an adverse effect on Sunrise's
financial condition or earnings.
 
FAILURE TO COMPLY WITH EXISTING ENVIRONMENTAL LAWS REGARDING MANAGEMENT OF
INFECTIOUS MEDICAL WASTE COULD ADVERSELY AFFECT OUR BUSINESS AND FINANCIAL
CONDITION
 
     Some of Sunrise's facilities generate infectious medical waste due to the
illness or physical condition of the residents, including, for example, blood
soaked bandages, swabs and other medical waste products and incontinence
products of those residents diagnosed with an infectious disease. The management
of infectious medical waste, including handling, storage, transportation,
treatment and disposal, is subject to regulation under various laws, including
federal and state environmental laws. These environmental laws set forth the
management requirements, as well as permit, recordkeeping, notice and reporting
obligations. Each of Sunrise's facilities has an agreement with a waste
management company for the proper disposal of all infectious medical waste. Any
finding that we are not in compliance with these environmental laws could
adversely affect our business operations and financial condition. Because these
environmental laws are amended from time to time, Sunrise cannot predict when
and to what extent liability may arise. In addition, because these environmental
laws vary from state to state, expansion of Sunrise's operations to states where
Sunrise does not currently operate may subject Sunrise to additional
restrictions on the manner in which it operate its facilities.
 
LIABILITY CLAIMS AGAINST SUNRISE IN EXCESS OF INSURANCE LIMITS COULD ADVERSELY
AFFECT SUNRISE'S FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The assisted living business entails an inherent risk of liability. In
recent years, Sunrise and Karrington, as well as other participants in our
industry, have become subject to an increasing number of lawsuits alleging
negligence or related legal theories. Many of these lawsuits involve large
claims and significant legal costs. Sunrise maintains insurance policies in
amounts and with the coverage and deductibles it believes are adequate based on
the nature and risks of our business, historical experience and industry
standards. The insurance currently maintained by Sunrise has the following
coverage limits:

our financial condition and results of operations could be materially and
adversely affected. Claims against us, regardless of their merit or eventual
outcome, also could have a material adverse effect on our ability to attract
residents or expand our business and could require Sunrise's management to
devote time to matters unrelated to the operation of our business. We also have
to renew our policies every year and we cannot be sure that we will be able to
continue to obtain liability insurance coverage on acceptable terms.
 
VARIOUS MARKET AND OTHER FACTORS HAVE CAUSED, AND COULD IN THE FUTURE CAUSE,
VOLATILITY IN SUNRISE'S STOCK PRICE
 
     The market price of Sunrise common stock has fluctuated, and may fluctuate
in the future, significantly in response to various factors and events,
including:
 
     - fluctuations in Sunrise's operating results;
 
     - changes in securities analysts' earnings estimates or recommendations;
       and
 
     - publicity about Sunrise or other companies in the assisted living
       industry.
 
Also, in recent months, the stock market has experienced broad price and volume
fluctuations that, in many cases, have been unrelated to the performance of
particular companies. These fluctuations, as well as upgrades and downgrades in
analysts' recommendations of our stock, have affected the market price of
Sunrise common stock in the past and could do so in the future. In addition, the
adoption of new statutes or regulations affecting the health care or assisted
living industries, or changes in the interpretation of existing statutes and
regulations, could impact our stock price.
 
EXISTING STOCKHOLDERS AND MANAGEMENT OF SUNRISE HAVE SIGNIFICANT INFLUENCE OVER
MATTERS REQUIRING THE APPROVAL OF STOCKHOLDERS
 
     The Klaassens own approximately 14.4% of the outstanding Sunrise common
stock. The executive officers and directors of Sunrise as a group, including the
Klaassens, beneficially own approximately 17.0% of the outstanding Sunrise
common stock. As a result, the Klaassens' and Sunrise's other executive officers
and directors have significant
 
                                       25
<PAGE>   35
 
influence over matters requiring the approval of Sunrise stockholders, including
business combinations and the election of directors.
 
ANTI-TAKEOVER PROVISIONS IN SUNRISE'S GOVERNING DOCUMENTS AND UNDER DELAWARE LAW
COULD MAKE IT MORE DIFFICULT TO EFFECT A CHANGE IN CONTROL OF SUNRISE EVEN IF IT
WERE IN THE BEST INTERESTS OF SUNRISE STOCKHOLDERS
 
     The certificate of incorporation and bylaws of Sunrise and Delaware law
contain provisions that could make it more difficult for a third party to obtain
control of Sunrise or discourage an attempt to do so. In addition, these
provisions could limit the price some investors are willing to pay for Sunrise
common stock. These provisions include:
 
         Board authority to issue preferred stock without stockholder
     approval.   The board of directors of Sunrise is authorized to issue
     preferred stock having a preference as to dividends or liquidation over the
     common stock without stockholder approval. The issuance of preferred stock
     could adversely affect the voting power of the holders of Sunrise common
     stock and could be used to discourage, delay or prevent a change in control
     of Sunrise.
 
         Staggered board and board sized fixed with range.   The board of
     directors is divided into three classes. The total number of directors is
     fixed by a two-thirds vote of the board within a range of a minimum of two
     and a maximum of 11. These provisions may make it more difficult for a
     third party to gain control of the board of directors of Sunrise. At least
     two annual meetings of stockholders, instead of one, would generally be
     required to effect a change in a majority of the board of directors.
 
         Other constituency provision.   The board of directors of Sunrise is
     required under Sunrise's certificate of incorporation to consider other
     constituencies, such as employees, residents, their families and the
     communities in which Sunrise and its subsidiaries operate, in evaluating
     any proposal to acquire Sunrise. This provision may allow the board of
     directors to reject an acquisition proposal even though the proposal was in
     the best interests of Sunrise stockholders.
 
         Call of special meetings.   A special meeting of Sunrise stockholders
     may be called only by the chairman of the board, the president, by a
     majority of the directors or by stockholders possessing at least 25% of the
     voting power of the issued and outstanding voting stock entitled to vote
     generally in the election of directors. This provision limits the ability
     of stockholders to call special meetings.
 
         Supermajority vote of stockholders or the directors required for bylaw
     amendments.   A two-thirds vote of the outstanding shares of common stock
     is required for stockholders to amend the bylaws. Amendments to the bylaws
     by directors of Sunrise require approval by at least a two-thirds vote of
     the directors. These provisions may make more difficult bylaw amendments
     that stockholders may believe are desirable.
 
         Two-thirds stockholder vote required to approve some amendments to the
     certificate of incorporation.   A two-thirds vote of the outstanding shares
     of common
 
                                       26
<PAGE>   36
 
     stock is required for approval of amendments to the foregoing provisions
     which are contained in Sunrise's certificate of incorporation. All
     amendments to the certificate of incorporation must first be proposed by a
     two-thirds vote of directors. These supermajority vote requirements may
     make more difficult amendments to these provisions of the certificate of
     incorporation that stockholders may believe are desirable.
 
         Advance notice bylaw.   Sunrises has an advance notice bylaw provision
     requiring stockholders intending to present nominations for directors or
     other business for consideration at a meeting of stockholders to notify
     Sunrise not later than 60 days before the meeting or 15 days after the date
     notice of the meeting is mailed or public notice of the meeting is given,
     if less than 75 days' notice of the date of the meeting is given or made to
     stockholders. This provision limits the ability of stockholders to make
     nominations for directors or introduce other proposals that are not timely
     received for consideration at a meeting.
 
     In addition to the anti-takeover provisions described above, Sunrise is
subject to Section 203 of the Delaware General Corporation Law. Section 203
generally prohibits a person owning 15% or more of its outstanding common stock
from engaging in a business combination with Sunrise for three years after the
person acquired the stock. However, this prohibition does not apply if (A) the
board of directors approves in advance the person's acquisition of the shares or
the business combination or (B) the business combination is approved by Sunrise
stockholders by a vote of at least a two-thirds of the outstanding shares not
owned by the acquiring person. When Sunrise was formed in December 1994, the
Klaassens and their respective affiliates and estates were exempted from this
provision.
 
THE BOARD OF DIRECTORS OF SUNRISE HAS ADOPTED A STOCKHOLDER RIGHTS PLAN THAT
COULD DISCOURAGE A THIRD PARTY FROM MAKING A PROPOSAL TO ACQUIRE SUNRISE
 
     In 1996, the board of directors of Sunrise adopted a stockholder rights
plan, which may discourage a third party from making a proposal to acquire
Sunrise. Under the plan, preferred purchase rights, which are attached to
Sunrise common stock, generally will be triggered upon the acquisition of 20% or
more of the outstanding common stock of Sunrise, unless the board of directors
redeems the rights. If triggered, these rights would entitle Sunrise
stockholders other than the acquiror to purchase Sunrise common stock, and
possibly the common stock of the acquiror, at a price equal to one-half the
market value of Sunrise common stock.
 
SUNRISE MAY BE ADVERSELY IMPACTED BY YEAR 2000 ISSUES, MANY OF WHICH ARE BEYOND
ITS CONTROL
 
     Impact of Year 2000.   Some of the older computer programs utilized by
Sunrise were written using two digits rather than four to define the applicable
year. As a result, those computer programs have time-sensitive software that
recognize a date using "00" as the year 1900 rather than the year 2000. This
could cause a system failure or
 
                                       27
<PAGE>   37
 
miscalculations causing disruptions of operations, including a temporary
inability to process transactions, send invoices or engage in similar normal
business activities.
 
     State of Readiness.   Sunrise started to formulate a plan to address the
year 2000 issue in late 1996. Sunrise has given its vice president of
information technology specific responsibility for managing its year 2000 plan.
This vice president leads a multi-disciplinary team to make Sunrise's mission
critical information technology systems and embedded systems year 2000 ready.
Sunrise's plan for mission critical information technology systems consists of
four phases:
 
     - inventory -- identifying all mission critical information technology
       systems and risk rating each according to its potential business impact;
 
     - assessment -- identifying mission critical information technology systems
       that use date functions and assessing them for year 2000 functionality;
 
     - remediation -- reprogramming, or replacing where necessary, inventoried
       items to ensure they are year 2000 ready; and
 
     - testing -- including date testing and performing quality assurance
       testing to ensure successful operation in the post-1999 environment.
 
     Sunrise completed the inventory and assessment phases for substantially all
of its mission critical information technology systems by year-end 1997.
Sunrise's mission critical information technology systems are currently in the
remediation and testing phases. Mission critical information technology systems
implemented or updated that are year 2000 compliant include:
 
     - the accounting general ledger system;
 
     - the resident billing system;
 
     - the cash disbursement or accounts payable system;
 
     - the development or project cost system;
 
     - the fixed asset system;
 
     - the employee stock option system;
 
     - the payroll and human resource system; and
 
     - substantially all software residing on Sunrise's home office and facility
       desk-top and lap-top computers.
 
Sunrise plans to complete the remediation of substantially all of its mission
critical systems by mid-1999. Sunrise plans to complete the testing of all of
its mission critical information technology systems by September 1999.
 
     Sunrise is approximately 75% complete its assessment of embedded systems
and expects to complete its assessment in March 1999. Sunrise's remaining steps
will then include testing selected embedded systems and remediating and testing
systems that exhibit year 2000 issues. Sunrise intends to focus its testing and
remediation efforts on select embedded systems at Sunrise's facilities, such as
telephone, elevator, security,
 
                                       28
<PAGE>   38
 
HVAC and similar systems. Sunrise plans to complete the assessment, remediation
and testing of these systems by year-end 1999.
 
     External Relationships.   Sunrise also faces the risk that one or more of
its critical vendors will not be able to interact with Sunrise due to the third
party's inability to resolve its own year 2000 issues, including those
associated with its own external relationships. Sunrise has completed its
inventory of external relationships and is attempting to determine the overall
year 2000 readiness of its external relationships. In the case of mission
critical suppliers, such as banks, financial intermediaries, including stock
exchanges, telecommunications providers and other utilities, Sunrise is engaged
in discussions with the third parties and is attempting to obtain detailed
information as to those parties' year 2000 plans and state of readiness.
Sunrise, however, does not have sufficient information at the current time to
predict whether its external relationships with mission critical suppliers will
be year 2000 ready.
 
     Year 2000 Costs.   Sunrise estimates on a preliminary basis that the cost
of assessment, remediation, testing and certification of its internal systems
will range from approximately $500,000 to $1,500,000. The major components of
these costs are: consultants, new software and hardware, software upgrades and
travel expenses. Sunrise expects that these costs will be funded through
operating cash flows. This estimate is based on currently available information.
Sunrise's year 2000 costs may increase once it has determined the year 2000
readiness of its vendors, customers and other third parties. In addition, the
availability and cost of consultants and other personnel trained in this area
and any future acquisitions may materially affect the estimated costs.
 
     No Assurance that Sunrise Can Fully Implement Its Year 2000 Plan.   The
year 2000 issue involves significant risks. There can be no assurance that
Sunrise will succeed in fully implementing its year 2000 plan. The following
describes Sunrise's most reasonably likely worst-case scenario, given current
uncertainties. If Sunrise's remediated internal mission critical information
technology systems fail upon testing, or any software application or embedded
microprocessors central to Sunrise's operations are overlooked in the assessment
or implementation phases, Sunrise may incur significant problems, including
delays in billing its residents. If Sunrise's vendors or suppliers fail to
provide its facilities with necessary power, telecommunications, transportation
and financial services, equipment and services, Sunrise will be unable to
provide services to its residents. If any of these uncertainties were to occur,
Sunrise's business, revenues and results of operations would be adversely
affected. Sunrise is unable at this time to assess the likelihood of these
events occurring or the extent of the effect on Sunrise.
 
     Year 2000 Forward-Looking Statements.   The foregoing year 2000 discussion
contains "forward-looking statements" within the meaning of the Private
Securities Litigation Reform Act of 1995. These statements, including
anticipated costs and the dates by which Sunrise expects to complete actions,
are based on management's best current estimates, which were derived utilizing
numerous assumptions about future events, including the continued availability
of resources, representations received from third parties and other factors.
However, there can be no guarantee that these estimates will be achieved, and
actual results could differ materially from those anticipated.
 
                                       29
<PAGE>   39
 
Specific factors that might cause material differences include the ability to
identify and remediate all relevant mission critical information technology and
non-mission critical information technology systems, results of year 2000
testing, adequate resolution of year 2000 issues by businesses and other third
parties who are service providers and suppliers of Sunrise, unanticipated system
costs, the adequacy of and ability to develop and implement contingency plans
and similar uncertainties. The "forward-looking statements" made in the previous
year 2000 discussion speak only as of the date on which the statements are made.
Sunrise undertakes no obligation to update any forward-looking statement to
reflect events or circumstances after the date on which the statement is made or
to reflect the occurrence of unanticipated events.

                   SPECIAL MEETING OF KARRINGTON SHAREHOLDERS
 
TIME AND PLACE OF SPECIAL MEETING
 
     The special meeting of Karrington shareholders will be held at
                  , on May    , 1999, at                   :00 a.m., local time.
 
MATTERS TO BE CONSIDERED
 
     At the special meeting, you will be asked to consider and vote on (A) the
proposal to adopt the amended merger agreement and to approve the merger; and
(B) such other business as may properly come before the special meeting.
 
VOTE REQUIRED; BOARD RECOMMENDATION
 
     The affirmative vote of the holders of at least two-thirds of the
outstanding Karrington common shares is required to adopt the amended merger
agreement and approve the merger. YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
THAT YOU VOTE IN FAVOR OF THE ADOPTION OF THE AMENDED MERGER AGREEMENT AND
APPROVAL OF THE MERGER.
 
     Each of Karrington's directors and executive officers and JMAC, Inc.,
Karrington's largest shareholder, have entered into shareholder agreements, as
amended, with Sunrise. Under these amended shareholder agreements, the directors
and executive officers of Karrington and JMAC, Inc. have granted Sunrise an
irrevocable proxy to vote all of their Karrington common shares in favor of the
amended merger agreement and the merger and against any competing third party
transaction. The directors and executive officers of Karrington and JMAC, Inc.
own 3,038,068 Karrington common shares, representing approximately 44.4% of the
outstanding Karrington common shares. Accordingly, of the 3,801,300 remaining
outstanding Karrington common shares held by nonaffiliates, only 40.0%, or
1,521,511 of such shares, must be voted in favor of the amended merger agreement
and the merger to satisfy the two-thirds vote requirement to adopt the amended
merger agreement and approve the merger.
 
VOTING OF PROXIES
 
     If the accompanying proxy card is properly signed and returned to
Karrington prior to the special meeting and not revoked, it will be voted as
instructed by you. If no instructions are given, the persons designated as
proxies in the accompanying proxy card will vote your shares "FOR" the adoption
of the amended merger agreement and the approval of the merger.
 
     A properly executed proxy marked "ABSTAIN" will be counted for determining
whether there is a quorum and for determining the aggregate voting power and
number of shares represented and entitled to vote at the special meeting.
However, it will not be voted. Accordingly, since the affirmative vote of the
holders of at least two-thirds of the outstanding Karrington common shares is
required to adopt the amended merger agreement and approve the merger, a proxy
marked "ABSTAIN" will have the effect of a vote "AGAINST" adoption of the
amended merger agreement and approval of the merger.
 
                                       31
<PAGE>   41
 
     Under Nasdaq Stock Market rules, brokers and nominees who hold shares in
their names but are not the beneficial owners of the shares may not exercise
voting discretion with respect to these shares. Thus, brokers and nominees may
not vote Karrington common shares held by them absent specific instructions from
the beneficial owners of the shares. Accordingly, since the affirmative vote of
the holders of at least two-thirds of the outstanding Karrington common shares
is required to adopt the amended merger agreement and approve the merger, a
broker non-vote proxy will have the effect of a vote "AGAINST" the adoption of
the amended merger agreement and approval of the merger.
 
     Your board of directors is not currently aware of any matters other than
those referred to in this proxy statement/prospectus which will come before the
special meeting. If any other matter should be presented at the special meeting
for action, the persons named in the accompanying proxy card will vote the proxy
in their own discretion.
 
REVOCATION OF PROXIES
 
     You may revoke your proxy at any time before it is voted at the special
meeting. To revoke your proxy, you may either deliver written notice of
revocation to the Secretary of Karrington, submit a subsequently dated proxy or
attend the special meeting and vote in person. Attendance at the special meeting
will not, in itself, constitute revocation of your proxy.
 
DISSENTERS' RIGHTS
 
     Under Ohio law, you may elect to dissent from the merger and to have the
fair cash value of your shares determined by a court and paid to you in cash. If
you exercise dissenters' rights, you must not vote in favor of the adoption of
the amended merger agreement and approval of the merger. You also must serve a
written demand on Karrington on or before the 10th day following the special
meeting. See "The Merger -- Rights of Dissenting Shareholders" for additional
information.
 
RECORD DATE; QUORUM
 
     Only holders of record of Karrington common shares on March 15, 1999 will
be entitled to notice of and to vote at the special meeting or any adjournments
or postponements. As of March 15, 1999, there were 6,839,368 Karrington common
shares outstanding. Each Karrington common share entitles the holder to one vote
per share. There are no other voting securities of Karrington outstanding.
 
     A majority of the outstanding Karrington common shares entitled to vote,
present in person or by proxy, will constitute a quorum for the transaction of
business at the special meeting.
 
COST OF SOLICITING PROXIES; MAILING DATE
 
     The cost of soliciting the proxies from the Karrington shareholders will be
borne by Karrington. However, Sunrise and Karrington have each agreed to pay one
half of the
 
                                       32
<PAGE>   42
 
expenses of the printing and mailing of this proxy statement/prospectus. In
addition to the solicitation of proxies by mail, proxies may be solicited
personally or by telephone, mail or telegram. Officers or employees of
Karrington may assist with personal or telephone solicitation and will receive
no additional compensation for this assistance. Karrington also will reimburse
brokerage houses and other nominees for their reasonable expenses in forwarding
proxy materials to beneficial owners of Karrington common shares.
 
     This proxy statement/prospectus and the accompanying form of proxy are
first being mailed to Karrington shareholders on or about April    , 1999.

                                   THE MERGER
 
GENERAL
 
     Subject to the terms of the amended merger agreement, Buckeye Merger
Corporation, which was recently formed by Sunrise to accomplish the merger, will
merge into Karrington, with Karrington as the surviving corporation in the
merger. As a result of the merger:
 
     - Karrington will become a wholly owned subsidiary of Sunrise; and
 
     - Each outstanding Karrington common share, other than shares held by
       Karrington shareholders who exercise dissenters' rights, will be
       converted into .3333 of a share of Sunrise common stock. Cash will be
       paid instead of the issuance of fractional shares.
 
In addition, each share of Sunrise common stock received by Karrington
shareholders in the merger will have attached to it the right to purchase shares
of series C junior participating preferred stock of Sunrise under its
stockholder rights plan.
 
BACKGROUND OF THE MERGER
 
     Since mid-1997, Karrington has actively taken steps to realign its business
and operational needs in an effort to sustain its development despite capital
constraints. In January 1998, Karrington engaged BT Alex. Brown Incorporated to
assist it in evaluating its strategic alternatives. The senior management of
Karrington and, later, at the direction of Karrington, BT Alex. Brown also had
informal discussions from time to time with the management and representatives
of other providers of assisted living services, including Sunrise, regarding
potential business combination transactions. These informal discussions were
exploratory and did not result, during this time, in any agreement with respect
to a potential transaction.
 
     Beginning in the summer of 1998, industry and economic factors, as well as
stock market volatility, made it much more difficult for companies like
Karrington to access the capital markets. On August 11, 1998, in its continuing
effort to remain apprised of and to evaluate the various alternatives available
to enhance and maximize shareholder value, the Karrington board of directors
asked management to explore the strategic options that might be available to
Karrington. On August 20, 1998, Karrington's management met with representatives
of BT Alex. Brown to discuss generally the trends in the assisted living
industry and to discuss alternative means of obtaining an infusion of capital
for purposes of continuing Karrington's development plans.
 
     On September 15, 1998, representatives of Karrington and BT Alex. Brown met
to review the financial operations of Karrington and to discuss strategic
alternatives. Among the alternatives that were discussed were an investment in
Karrington by a third party, continuing to operate without a capital infusion
and a sale of Karrington. After consideration of these alternatives, the board
of directors of Karrington preliminarily concluded that the continuing
difficulty for companies like Karrington to access the capital markets made
continuing as an independent company without a capital infusion
 
                                       34
<PAGE>   44
 
an unattractive alternative. Pursuing an investment by a third party or a sale
of Karrington emerged as the most attractive means of addressing Karrington's
capital requirements. However, in light of the depressed market for Karrington
common shares, the board of directors of Karrington believed that the number of
shares a potential investor would likely require would significantly dilute
existing shareholder value. Therefore, a potential sale was considered to be an
especially attractive alternative.
 
     Among the potential alternative sale transactions considered internally by
the Karrington board of directors was the possibility of a merger with Sunrise.
The managements of Karrington and Sunrise have been familiar with each other for
a number of years, and the two companies have maintained similar operating
philosophies. After the September 15, 1998 meeting, the executive committee of
the board of directors of Karrington gave approval to Karrington's
representatives to enter into preliminary discussions with Sunrise regarding a
possible business transaction. Karrington's representatives were not given
permission to engage in negotiations with respect to a possible transaction with
any party other than Sunrise.
 
     On September 17, 1998, representatives of Karrington, Sunrise and BT Alex.
Brown met to discuss the operations of Karrington and the possibility of a
strategic combination of Karrington and Sunrise. Karrington and Sunrise agreed
at the meeting that, in view of the competitive environment of the assisted
living industry and in view of the trend toward consolidation, a business
combination could have benefits for both companies. Discussion between the
companies continued after this meeting. The executive committee of the board of
directors of Karrington met on September 24 and 30, 1998, and authorized
Karrington's representatives to conduct mutual due diligence investigations.
 
     On October 8, 1998, Karrington and Sunrise executed a confidentiality
agreement. Under the confidentiality agreement, the parties agreed to exchange
confidential information and to refrain from efforts to acquire ownership in or
control of the other without permission of the other company's board of
directors.
 
     Between October 5 and October 9, 1998, representatives of Karrington and
Sunrise, along with their respective financial advisors, conducted due diligence
on both companies. Senior management of each of the companies, along with their
respective legal advisors, commenced the negotiation of the terms of a proposed
merger agreement, the option agreement and related agreements. The parties
reached tentative agreement on the financial terms for a business combination on
October 10, 1998.
 
     At a special meeting of the board of directors of Karrington on October 11,
1998, senior management of Karrington, together with its legal and financial
advisors, reviewed for the board of directors of Karrington the strategic
investigation and due diligence they had conducted, the discussions and contacts
with Sunrise to date, the historical performance of Karrington and Sunrise, the
financial terms of the proposed transaction with Sunrise, including the exchange
ratio and the preliminary terms of the merger agreement, option agreement and
related agreements. BT Alex. Brown reviewed the financial analyses described in
"Opinion of Karrington's Financial Advisor." Following such discussion and
questions by the board of directors of Karrington to Karrington
 
                                       35
<PAGE>   45
 
senior management and its financial and legal advisors, the members of the board
of directors of Karrington gave preliminary approval to management to negotiate
definitive agreements. Due diligence and negotiations continued during the week
of October 12 to 18, 1998.
 
     At a telephonic meeting held on October 18, 1998, the board of directors of
Karrington discussed and reviewed the final terms of the proposed merger
agreement, the option agreement for 9.9% of the outstanding Karrington common
shares to be entered into with Sunrise and related agreements. BT Alex. Brown
issued its oral opinion, which opinion was subsequently confirmed in all
material respects by delivery of a written opinion dated October 18, 1998, to
the effect that, as of that date and based upon and subject to the matters
stated in its opinion, the exchange ratio was fair, from a financial point of
view, to the holders of Karrington common shares. Following these discussions,
and questions by the board of directors of Karrington to Karrington senior
management and its financial and legal representatives, the board of directors
of Karrington voted unanimously to approve the merger agreement, the merger, the
option agreement for 9.9% of the outstanding Karrington common shares to be
entered into with Sunrise and the related transactions.
 
     In early February 1999, it became unlikely that the parties would be in a
position to complete the merger by March 31, 1999. In addition, it became clear
that, if the merger were not completed by March 31, 1999, Karrington would need
additional working capital funds to continue operations until the closing. As a
result, in early February 1999 representatives of Sunrise contacted
representatives of Karrington regarding proposed amendments to the merger
agreement.
 
     Between early February 1999 and the beginning of March 1999,
representatives of Sunrise and Karrington held numerous conversations regarding
proposed amendments to the merger agreement. In addition to discussing an
extension of the termination date under the merger agreement from March 31, 1999
to June 30, 1999, the parties discussed the terms under which Sunrise would
provide an additional $6.5 million working capital line of credit to Karrington.
Through these discussions, Sunrise indicated its willingness to provide the
additional $6.5 million line of credit if Karrington agreed to a fixed exchange
ratio of 0.3333. Sunrise common stock had been trading at or above the 0.3333
exchange ratio level since the merger was announced. In addition, the parties
agreed that, since Sunrise had begun providing management and consulting
services to Karrington, some of the conditions to closing in the original merger
agreement relating to the conduct of Karrington's business prior to closing were
no longer necessary.
 
   
     On March 3, 1999, the Karrington board of directors approved the terms of
the proposed amendment no. 1 to the merger agreement. On March 4, 1999,
Karrington received an updated opinion from BT Alex. Brown and Karrington,
Sunrise and Buckeye Merger Corporation executed amendment no. 1 to the merger
agreement.
    
 
RECOMMENDATION OF THE KARRINGTON BOARD
 
     The board of directors of Karrington has determined that the merger is in
the best interests of the shareholders of Karrington, has unanimously approved
the amended
 
                                       36
<PAGE>   46
 
merger agreement, the merger, the option agreement and the related transactions
and unanimously recommends that shareholders vote to adopt the amended merger
agreement and approve the merger at the special meeting.
 
KARRINGTON'S REASONS FOR THE MERGER
 
     In reaching its conclusion that the merger is in the best interests of
Karrington and its shareholders and in approving the merger, the amended merger
agreement, the option agreement and the related transactions, the Karrington
board of directors considered and reviewed with Karrington's management, as well
as its financial and legal advisors, a number of factors. The following are the
material factors considered by the Karrington board of directors:
 
     - the business, financial condition, operations, earnings and prospects of
       Sunrise, including, its potential growth, development, and profitability
       and the related business risks;
 
     - the business, financial condition, operations, earnings and prospects of
       Karrington, including the funding and operating pressures facing
       Karrington in the current operating environment;
 
     - industry and economic factors, including consideration of:
 
       - trends toward consolidation;
 
       - the greater access to capital available to larger companies; and
 
       - competitive and financial challenges facing Karrington as an
         independent entity.
 
     - the scale of Sunrise, operating 77 facilities in 13 states with over
       6,630 residents while owning over 86% of its facilities;
 
     - the limited geographic overlap of existing Karrington and Sunrise
       markets, resulting in a combined territory which will allow for market
       expansion and opportunities to achieve cost savings on a regional basis;
 
     - the nature and compatibility of Sunrise's management and business
       philosophy, based on the ten-year long business and personal relationship
       of Paul Klaassen and Richard R. Slager, the founders of Sunrise and
       Karrington, respectively, and the fact that Sunrise had provided
       consulting services, personnel advice, information, data programs and
       systems to Karrington between 1989 and 1995;
 
     - Sunrise common stock is more widely held than Karrington common shares,
       which is expected to provide Karrington shareholders with increased
       liquidity;
 
     - based on the closing price of Sunrise common stock on October 16, 1998,
       the last trading day immediately before the public announcement of the
       merger, each Karrington common share would have been converted into the
       right to receive a fraction of a share of Sunrise common stock having a
       value of $12.00, a 32.4% premium over the $9.06 closing price of
       Karrington common shares on the day immediately before public
       announcement of the merger;
 
     - the terms of the amended merger agreement and the option agreement as
       negotiated, including the potential impact of these proposed agreements
       on other parties that might have an interest in a business combination
       with Karrington,
 
                                       37
<PAGE>   47
 
       and the negotiation process, each of which was approved and adopted by
       the Karrington board of directors as being advisable and fair to, and in
       the best interests of, the Karrington shareholders;
 
     - the merger agreement is intended to constitute a "plan of reorganization"
       within the meaning of Section 1.368-2(g) of the income tax regulations
       under the Internal Revenue Code;
 
     - the opinion of BT Alex. Brown as to the fairness, from a financial point
       of view, of the exchange ratio to the holders of Karrington common
       shares;
 
     - the effects of the merger on Karrington's other constituencies, including
       its employees and customers and on the communities in which Karrington
       maintains facilities; and
 
     - the interests of Karrington directors and executive officers and
       Karrington's principal shareholder may conflict with the interests of
       Karrington shareholders, as generally described in this proxy
       statement/prospectus under the caption "The Merger -- Interests of
       Certain Persons in the Merger." The board of directors of Karrington was
       fully aware of these interests when it unanimously approved the amended
       merger agreement and the transactions contemplated by the amended merger
       agreement.
 
     The board of directors of Karrington also considered a variety of risks and
other potentially negative factors concerning the merger. These include the
following:
 
     - the merger agreement, as amended, does not provide for any adjustment to
       the exchange ratio based on changes in market prices and, as a result,
       the value of the Sunrise common stock that Karrington shareholders will
       receive in the merger will vary depending on changes in the market price
       of Sunrise common stock;
 
     - the termination fee and option granted to Sunrise by Karrington may
       prevent others from proposing alternative transactions that may be more
       advantageous to Karrington shareholders; and
 
     - Karrington is giving up the ability to realize its full potential as an
       independent company.
 
     The foregoing discussion of the information and factors considered by
Karrington is not meant to be exhaustive, but includes the material facts
considered by the board of directors of Karrington. The board of directors of
Karrington did not specifically adopt the conclusions of the opinion of BT Alex.
Brown referred to above. The BT Alex. Brown opinion was only one of many factors
considered by the board of directors of Karrington in its evaluation of the
merger. In reaching its determination to approve the amended merger agreement
and the related transactions, the board of directors of Karrington did not
assign any relative or specific weight to the foregoing factors. Individual
directors may have considered each factor differently.

<PAGE>   48
 
SUNRISE'S REASONS FOR THE MERGER
 
     Sunrise's reasons for the merger include:
 
     - the merger will allow Sunrise to expand rapidly into complementary
       markets in the midwestern and eastern United States in which there is
       little geographic overlap with existing Sunrise facilities;
 
     - the merger will allow Sunrise to increase its development pipeline from
       71 facilities with a resident capacity of approximately 6,030 units to 89
       facilities with a resident capacity in excess of 7,300 units; and
 
     - the merger will allow Sunrise to combine its superior ability to access
       capital with Karrington's development activities.
 
   
     Sunrise intends to sell 17 Karrington facilities within 12 months following
the merger. Most of the Karrington facilities Sunrise intends to sell are
Karrington Cottage prototype models consisting of 20 or less units. These
facilities are located in smaller midwestern markets where cost savings from
clustering of facilities generally is not possible due to the size of the
markets. By comparison, the Sunrise prototype model consists of approximately 75
units and typically is located in a major metropolitan or suburban market where
efficiencies can be achieved by clustering facilities. Please refer to
"Properties" on page 81 for additional information regarding the Karrington
facilities Sunrise intends to sell following the merger.
    
 
OPINION OF KARRINGTON'S FINANCIAL ADVISOR
 
     Karrington engaged BT Alex. Brown to act as its exclusive financial advisor
in connection with the merger. On October 18, 1998, the board of directors of
Karrington held a meeting to evaluate the proposed merger. At the meeting, BT
Alex. Brown rendered to the board of directors of Karrington an oral opinion,
subsequently confirmed in all material respects by a written opinion dated
October 18, 1998, to the effect that, as of that date and based upon and subject
to the matters stated in the opinion, the exchange ratio was fair, from a
financial point of view, to the holders of Karrington common shares. In
connection with the amendment to the merger agreement dated as of March 4, 1999,
BT Alex. Brown confirmed its earlier opinion by delivery of a written opinion
dated March 4, 1999. In connection with its opinion dated March 4, 1999, BT
Alex. Brown updated, as appropriate, the analyses performed in connection with
its earlier opinion. In addition, BT Alex. Brown reviewed the assumptions on
which the analyses were based and the factors considered in connection with its
earlier opinion.
 
     The full text of the written opinion of BT Alex. Brown dated March 4, 1999,
which describes the assumptions made, matters considered and limitations of the
review undertaken, is attached as Appendix C to this proxy statement/prospectus
and is incorporated by reference. BT ALEX. BROWN'S OPINION IS DIRECTED TO THE
BOARD OF DIRECTORS OF KARRINGTON AND ADDRESSES ONLY THE FAIRNESS OF THE EXCHANGE
RATIO FROM A FINANCIAL POINT OF VIEW. BT ALEX. BROWN'S OPINION DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD
VOTE AT THE KARRINGTON SPECIAL
 
                                       39

MEETING. The summary of the opinion of BT Alex. Brown in the proxy statement/
prospectus is qualified in its entirety by reference to the full text of the
opinion.
 
     In connection with BT Alex. Brown's role as financial advisor to
Karrington, and in arriving at its opinion, BT Alex. Brown:
 
     - reviewed annual reports to stockholders of Karrington and Sunrise for the
       fiscal years ended December 31, 1996 and December 31, 1997;
 
     - reviewed documents filed by Karrington and Sunrise with the SEC during
       the two year period prior to the date of BT Alex. Brown's opinion,
       including annual reports on Form 10-K, quarterly reports on Form 10-Q and
       current reports on Form 8-K;
 
     - reviewed internal analyses and other information furnished to or
       discussed with BT Alex. Brown by Karrington, Sunrise and their advisors;
 
     - held discussions with the members of the senior management of Karrington
       and Sunrise regarding the business and prospects of their respective
       companies and the joint prospects of a combined company;
 
     - reviewed the reported prices and trading activity for Karrington common
       shares and Sunrise common stock;
 
     - compared financial and stock market information for Karrington and
       Sunrise with similar information for other companies whose securities are
       publicly traded;
 
     - reviewed the financial terms of recent business combinations which BT
       Alex. Brown deemed comparable in whole or in part to the merger;
 
     - reviewed the terms of the amended merger agreement and related documents;
       and
 
     - performed other studies and analyses and considered other factors as BT
       Alex. Brown deemed appropriate.
 
     BT Alex. Brown did not independently verify nor assume responsibility for
independent verification of any information, whether publicly available or
furnished to BT Alex. Brown, concerning Karrington, Sunrise or the combined
company, including any financial information, forecasts or projections
considered in connection with the rendering of its opinion. For purposes of its
opinion, BT Alex. Brown assumed and relied upon the accuracy and completeness of
all information which it reviewed. BT Alex. Brown did not conduct a physical
inspection of any of the properties or assets of Karrington or Sunrise. In
addition, BT Alex. Brown did not prepare or obtain any independent evaluation or
appraisal of any of the assets or liabilities of Karrington or Sunrise. With
respect to financial forecasts and projections made available to BT Alex. Brown
and used in its analyses, including the analyses and forecasts of cost savings,
refinancing savings and operational improvements expected by Karrington and
Sunrise to be achieved as a result of the merger, BT Alex. Brown assumed that
they were reasonably prepared on bases reflecting the best currently available
estimates and judgments of the management of Karrington or Sunrise. In rendering
its opinion, BT Alex. Brown expressed no view as to the reasonableness of the
forecasts and
 
                                       40
<PAGE>   50
 
projections, including the cost savings, refinancing savings and operational
improvements expected by Karrington and Sunrise to be achieved as a result of
the merger, or the assumptions on which they are based. BT Alex. Brown's opinion
was necessarily based upon economic, market and other conditions as in effect
on, and the information made available to BT Alex. Brown as of, the date of its
opinion.
 
     For purposes of rendering its opinion, BT Alex. Brown assumed that, in all
respects material to its analysis:
 
     - the representations and warranties of Karrington, Sunrise and Buckeye
       Merger Corporation contained in the amended merger agreement are true;
 
     - Karrington, Sunrise and Buckeye Merger Corporation will each perform all
       of the covenants and agreements to be performed by it under the amended
       merger agreement;
 
     - all conditions to the obligations of each of Karrington, Sunrise and
       Buckeye Merger Corporation to consummate the merger will be satisfied
       without any waivers;
 
     - all material governmental, regulatory or other approvals and consents
       required in connection with the consummation of the merger will be
       obtained; and
 
     - in connection with obtaining any necessary governmental, regulatory or
       other approvals and consents, or any amendments, modifications or waivers
       to any agreements, instruments or orders to which either Karrington or
       Sunrise is a party, or is subject or by which it is bound, no
       limitations, restrictions or conditions will be imposed or amendments,
       modifications or waivers made that would have a material adverse effect
       on Karrington or Sunrise or materially reduce the contemplated benefits
       of the merger to Karrington.
 
     BT Alex. Brown was informed by Karrington, and for purposes of rendering
its opinion BT Alex. Brown assumed, that the merger will qualify as a tax-free
reorganization for federal income tax purposes. In connection with its
engagement, BT Alex. Brown was not authorized to, and did not, solicit interest
from any other party with respect to the acquisition of all or a part of
Karrington. BT Alex Brown did not express an opinion as to the price at which
Sunrise common stock will trade at any time. No other instructions or
limitations were imposed by the board of directors of Karrington upon BT Alex.
Brown with respect to the investigations made or the procedures followed by it
in rendering its opinion.

     The following is a summary of the material analyses performed by BT Alex.
Brown in connection with its opinion to the Karrington board of directors dated
October 18, 1998. THE FINANCIAL ANALYSES SUMMARIZED BELOW INCLUDE INFORMATION
PRESENTED IN TABULAR FORMAT. IN ORDER TO FULLY UNDERSTAND BT ALEX. BROWN'S
FINANCIAL ANALYSES, THE TABLES MUST BE READ TOGETHER WITH THE TEXT OF EACH
SUMMARY. THE TABLES ALONE DO NOT CONSTITUTE A COMPLETE DESCRIPTION OF THE
FINANCIAL ANALYSES. CONSIDERING THE DATA SET FORTH BELOW WITHOUT CONSIDERING THE
FULL NARRATIVE DESCRIPTION OF THE FINANCIAL ANALYSES, INCLUDING THE
METHODOLOGIES AND ASSUMPTIONS UNDERLYING THE ANALYSES, COULD CREATE A MISLEADING
OR INCOMPLETE VIEW OF BT ALEX. BROWN'S FINANCIAL ANALYSES.
 
     Analysis of Selected Public Companies.   BT Alex. Brown compared financial
and stock market information for Karrington and Sunrise to the following
selected publicly held companies in the assisted living industry:
 
     - ARV Assisted Living, Inc.;
 
     - American Retirement Corporation;
 
     - Alternative Living Services, Inc.;
 
     - Assisted Living Concepts, Inc.;
 
     - Brookdale Living Communities, Inc.;
 
     - Capital Senior Living Corporation;
 
     - CareMatrix Corporation;
 
     - Emeritus Corporation; and
 
     - Regent Assisted Living, Inc.
 
In choosing the selected companies, BT Alex. Brown considered those companies
that had core businesses which consisted primarily of providing assisted living
services or which were of a similar size to Karrington. BT Alex. Brown
calculated equity market values as multiples of estimated calendar years 1999
and 2000 net income. BT Alex. Brown calculated lease adjusted enterprise values,
calculated as equity market value as adjusted for debt, cash and capitalized
operating leases, as multiples of revenues and earnings before interest, taxes,
depreciation, amortization and operating rents, each forecasted for the next 12
months by annualizing publicly available quarterly information ended June 30,
1998. All multiples were based on closing stock prices on October 16, 1998. Net
income estimates for the selected companies and Sunrise were based on analysts'
estimates as reported by Institutional Brokers Estimate System, a market
research database. Net income estimates for Karrington were based on internal
estimates of the management of Karrington. This analysis indicated the following
implied equity market value and lease adjusted enterprise value multiples for
the selected companies, as

In choosing the selected transactions, BT Alex. Brown focused on those
transactions for which information was publicly available involving the sale of
a majority of the voting shares of the target company. BT Alex. Brown calculated
equity market values as a multiple of the projected net income of the target
company two years after the announcement of the transaction. BT Alex. Brown
calculated lease adjusted enterprise values as multiples of revenues and
earnings before interest, taxes, depreciation, amortization and operating rents,
each forecasted for the next 12 months by annualizing the most recently
available quarterly information of the target prior to the announcement of the
transaction. All multiples were based on publicly available information at the
time of announcement of the relevant transaction. This analysis indicated the
following implied equity market value and lease adjusted enterprise value
multiples for the selected

     Premium Analysis.   BT Alex. Brown analyzed the premiums paid in 39 change
of control transactions having transaction values of between $100 and $300
million involving health care companies effected since January 1, 1996, based on
the target company's stock price one day and one month prior to public
announcement of the transaction. This analysis indicated the following average
and median premiums in the transactions, as compared to the implied premiums in
the merger one day, one month and based on the average closing price of
Karrington common shares during the one-month period prior to public
announcement of the merger:

     Discounted Cash Flow Analyses.   BT Alex. Brown performed discounted cash
flow analyses for each of Karrington and Sunrise on an independent basis
assuming the merger did not occur. This analysis estimates the present value of
the after-tax cash flows from operations, adjusted for capital expenditures and
excluding financing costs, that each of Karrington and Sunrise could generate
for the fiscal years ended 1999 through 2003. Financial data for this analysis
were based on internal estimates of the managements of Karrington and Sunrise.
BT Alex. Brown calculated the range of estimated values at the end of fiscal
year 2003 for Karrington and Sunrise by applying multiples at the end of fiscal
year 2003 ranging from 9.0x to 11.0x to the projected 2003 calendar year
earnings before interest, taxes, depreciation, amortization and operating rents
of Karrington and Sunrise. BT Alex. Brown discounted to present value the after-
tax cash flows from operations for the fiscal years ended 1999 through 2003 and
 
                                       44
<PAGE>   54
 
estimated values at the end of fiscal year 2003 using discount rates ranging
from 14% to 16% for Karrington and 11% to 13% for Sunrise. This analysis yielded
an implied range for Sunrise common stock of approximately $30.34 to $48.99 per
share, as compared to the closing price for Sunrise common stock on October 16,
1998 of $36.00. This analysis also yielded an implied range for Karrington
common shares of approximately $4.35 to $13.26 per share, as compared to the
equity value implied by the exchange ratio of 0.3611 as of October 18, 1998 had
the exchange ratio been determined in accordance with the formula in the merger
agreement on that date, of approximately $13.00 per share based on the closing
price of Sunrise common stock on October 16, 1998.
 
     Contribution Analysis.   BT Alex. Brown analyzed the relative contributions
of Karrington and Sunrise to the pro forma combined company of revenues and
earnings before interest, taxes, depreciation, amortization and operating rents,
each for the quarter ended June 30, 1998 annualized, and estimated net income
for calendar years 1999 and 2000. BT Alex. Brown then compared these
contributions to the equity ownership of the current holders of Karrington
common shares in the pro forma combined company. For this analysis, net income
estimates for Karrington were based on internal estimates of Karrington's
management and net income estimates for Sunrise were based on analysts'
estimates as reported by the Institutional Brokers Estimate System. This
analysis indicated the following contributions by Karrington and Sunrise, as
compared to the equity ownership of Karrington and Sunrise in the pro forma
combined company based on the implied exchange ratio of 0.3611 as of October 18,
1998 had the exchange ratio been determined in accordance with the formula in
the merger agreement on that date:

     Pro Forma Merger Analysis.   BT Alex. Brown analyzed, among other things,
the pro forma effects of the merger on the earnings per share of Sunrise in
calendar years 1999 and 2000, both before and after giving effect to cost
savings, refinancing savings and operational improvements anticipated by the
managements of Karrington and Sunrise to result from the merger, excluding
non-recurring merger costs. For this analysis, financial data for Karrington
were based on internal estimates of Karrington's management and financial data
for Sunrise were based on analysts' estimates as reported by the Institutional
Brokers Estimate System. This analysis indicated that the merger may result in
an increase to Sunrise's earnings per share in calendar years 1999 and 2000
assuming anticipated levels of cost savings, refinancing savings and operational
improvements were achieved, excluding non-recurring merger costs. The actual
operating or financial results achieved by the pro forma combined company may
vary from
 
                                       45
<PAGE>   55
 
projected results and variations may be material as a result of business and
operational risks, the timing, amount and costs associated with achieving cost
savings, refinancing savings and operational improvements, as well as other
factors.
 
     Historical Exchange Ratio Analysis.   BT Alex. Brown compared the exchange
ratio with the historical exchange ratio of the average daily closing prices of
Karrington common shares and Sunrise common stock over the one-day, 10-day,
one-month, three-month and six-month periods prior to announcement of the
merger. This analysis indicated the following historical exchange ratios over
these periods, as compared to an implied exchange ratio of 0.3611 as of October
18, 1998 had the exchange ratio been determined in accordance with the formula
in the merger agreement on that date, and the following implied premiums
obtained by dividing the exchange ratio by the historical exchange ratios over
these periods:

The implied premiums derived by comparing the historical exchange ratios to the
exchange ratio do not necessarily reflect the underlying market value of either
Karrington common shares or Sunrise common stock or how the Karrington common
shares, Sunrise common stock or the common stock of the pro forma combined
company may trade in the future.
 
     Other Factors.   In rendering its opinion, BT Alex. Brown also reviewed and
considered:
 
     - historical and projected financial data for Karrington and Sunrise;
 
     - historical market prices and trading volumes for Karrington common shares
       and Sunrise common stock and the relationship between movements in
       Karrington common shares, Sunrise common stock, the movements in the
       common stock of the selected companies and movements in the S&P 500
       Index; and
 
     - selected analysts' reports on Sunrise, including earnings per share and
       growth rate estimates of such analysts for Sunrise.
 
     The summary above describes the procedures followed, the bases and methods
utilized and the material analyses performed by BT Alex. Brown in connection
with its opinion dated October 18, 1998, and is not a complete description of BT
Alex. Brown's opinion or the financial analyses and factors considered by BT
Alex. Brown. The preparation of a fairness opinion is a complex analytic process
involving various determinations as to the most appropriate and relevant methods
of financial analyses and the application of those methods to the particular
circumstances and, therefore, a fairness opinion is not readily susceptible to
summary description.
 
                                       46
<PAGE>   56
 
     BT Alex. Brown's opinion was not based on any single factor or analysis.
Rather, BT Alex. Brown believed that the totality of the factors considered and
analyses performed by BT Alex. Brown in connection with its opinion operated
collectively to support its determination as to the fairness of the exchange
ratio from a financial point of view. BT Alex. Brown believes that its analyses
and the summary of its analyses must be considered as a whole and that selecting
portions of its analyses and factors or focusing on information presented in
tabular format, without considering all analyses and factors or the narrative
description of the analyses, could create a misleading or incomplete view of the
processes underlying its analyses and opinion.
 
     In performing its analyses, BT Alex. Brown made numerous assumptions with
respect to industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
Karrington and Sunrise. These assumptions included industry growth, the absence
of any material adverse change in the financial condition and prospects of
Karrington, Sunrise or the assisted living industry generally or in the
financial markets in general.
 
     No company, transaction or business used in BT Alex. Brown's analyses as a
comparison is identical to Karrington, Sunrise, the pro forma combined company
or the proposed merger, nor is an evaluation of the results of those analyses
entirely mathematical. Rather, these analyses involve complex considerations and
judgments concerning financial and operating characteristics and other factors
that could affect the merger, public trading or other values of the companies,
business segments or transactions being analyzed.
 
     The estimates contained in BT Alex. Brown's analyses and the ranges of
valuations resulting from any particular analysis are not necessarily indicative
of actual values or future results, which may be significantly more or less
favorable than those suggested by its analyses. In addition, analyses relating
to the value of businesses or securities do not purport to be appraisals or to
reflect the prices at which businesses or securities actually may be sold.
Accordingly, BT Alex. Brown's analyses and estimates are inherently subject to
substantial uncertainty.
 
     The type and amount of consideration payable in the merger was determined
through negotiation between Karrington and Sunrise. Although BT Alex. Brown
provided financial advice to Karrington during the course of these negotiations,
the decision to enter into the merger was solely that of the board of directors
of Karrington. BT Alex. Brown's opinion and financial analyses were only one of
many factors considered by the board of directors of Karrington in its
evaluation of the proposed merger and should not be viewed as determinative of
the views of Karrington's board of directors or management with respect to the
exchange ratio or the merger.
 
     BT Alex. Brown does not have any obligation to update, revise or reaffirm
its opinion dated March 4, 1999 and Karrington does not currently intend to
request an updated opinion from BT Alex. Brown. If a significant event affecting
the opinion occurs, such as a material amendment to the merger agreement
resulting in a material change to the exchange ratio, the Karrington Board
would, consistent with its fiduciary duties,
 
                                       47

     Severance and Stay Bonus Plan.   Karrington has adopted a severance and
stay bonus plan. The plan was designed to help ensure that employees at the
level of senior vice president and below will remain with Karrington until the
merger is completed and, in some cases, until transition work has been
completed, whether or not they are assured of continuing employment following
the merger. The following is a summary of benefits that will be paid under this
plan:
 
<TABLE>
<CAPTION>
       ELIGIBLE PARTICIPANTS                           AMOUNT
       ---------------------                           ------

  Karrington through various              3 weeks' to 8 weeks' salary
  transition dates set by Sunrise         depending on position
</TABLE>
 
     Indemnification; Directors' and Officers' Liability Insurance.   In the
amended merger agreement, Karrington and Sunrise have agreed to indemnify and
hold harmless, to the fullest extent permitted by Karrington's articles of
incorporation and code of regulations and Ohio law, in the case of Karrington,
and Delaware law, in the case of Sunrise, each person who on or prior to the
date of the merger agreement was at any time a director or officer of
Karrington. Each of these persons will be indemnified for acts or omissions, or
alleged acts or omissions, by them in their capacities as directors or officers
of Karrington occurring at or prior to the closing of the merger. Sunrise also
agreed to cause to remain in effect, for six years after the closing of the
merger, the current directors' and officers' liability insurance maintained by
Karrington covering acts or omissions occurring prior to the closing of the
merger, subject to a limitation on the annual premium expense required to be
paid by Sunrise.
 
     Karrington is not aware of any current or anticipated events which would
call for either Sunrise or Karrington to make indemnification payments to
directors or officers of Karrington.
 
     JMAC, Inc. to Have Representative Serve on Sunrise's Board.   Following the
merger, the board of directors of Sunrise will appoint Mr. Slager to the Sunrise
board as the representative of JMAC, Inc., Karrington's largest shareholder. As
long as JMAC, Inc. continues to beneficially own at least 500,000 shares of
Sunrise common stock, Sunrise has agreed to cause Mr. Slager to be re-nominated
and to solicit proxies for his re-election as a director of Sunrise or of such
other person designated by JMAC, Inc. who is reasonably acceptable to Sunrise.
JMAC, Inc. currently has three representatives serving on Karrington's board. In
the negotiation of the original merger agreement, Sunrise agreed to appoint a
single designee of JMAC, Inc. to Sunrise's board, as discussed above.

ACCOUNTING TREATMENT
 
     The merger will be treated as a purchase for financial accounting purposes.
This means that, for financial accounting purposes, Sunrise will allocate the
purchase price to assets acquired and liabilities assumed from Karrington based
on their estimated fair values at the time the merger is completed. The amount
of the purchase price that exceeds the net fair value of assets acquired and
liabilities assumed will be reflected on the balance sheet of Sunrise as
goodwill and will have to be written off against future earnings.
 
NASDAQ NATIONAL MARKET LISTING
 
     It is a condition to the closing of the merger that the shares of Sunrise
common shares issuable to Karrington's shareholders in the merger have been
listed on the National Market tier of the Nasdaq Stock Market. Sunrise has filed
the required notification form with the Nasdaq to list the shares.
 
REGULATORY MATTERS
 
     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, the merger
may not be consummated until (a) notifications have been given, and required
information has been furnished, to the Federal Trade Commission and the
Antitrust Division of the Department of Justice and (b) specified waiting period
requirements have been satisfied. In November 1998, Sunrise, Karrington and
JMAC, Inc. filed the requisite pre-merger filings with these government
authorities. On December 8, 1998, the Federal Trade Commission and the Antitrust
Division of the U.S. Department of Justice granted early termination of the
waiting period before the merger can be completed under the Hart-Scott-Rodino
Antitrust Improvements Act.
 
     Even though early termination of the waiting period has been granted, the
Federal Trade Commission, the Antitrust Division or others could take action
under the antitrust laws to challenge the merger, including to enjoin the merger
or seek divestiture of substantial assets by Sunrise or Karrington. The
obligations of Sunrise and Karrington to complete the merger are subject to the
condition that there is no court order or action by the Antitrust Division or
the Federal Trade Commission to prevent completion of the merger or that seeks
divestiture of substantial assets.
 
     Karrington is currently in the process of preparing required notice filings
to state licensure authorities of the proposed merger, and intends to file
promptly all required notices.
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER
 
     The following is a summary of the material anticipated U.S. federal income
tax consequences of the merger to holders of Karrington common shares who hold

U.S. federal income tax law. These persons include, for example:
 
     - non-U.S. persons;
 
     - financial institutions;
 
     - dealers in securities;
 
     - insurance companies;
 
     - tax-exempt entities;
 
     - dissenting shareholders;
 
     - holders who acquired their Karrington common shares upon the exercise of
       an employee stock option or right or otherwise as compensation; and
 
     - persons who hold Karrington common shares as part of a hedge, straddle or
       conversion transaction.
 
In addition, no information is provided in this proxy statement/prospectus with
respect to the tax consequences of the merger under applicable foreign, state or
local laws.
 
     KARRINGTON SHAREHOLDERS ARE URGED TO CONSULT WITH THEIR TAX ADVISORS
REGARDING THE TAX CONSEQUENCES OF THE MERGER TO THEM, INCLUDING THE EFFECTS OF
FEDERAL, STATE, LOCAL, FOREIGN AND OTHER TAX LAWS.
 
     General.   In connection with the filing of the registration statement of
which this proxy statement/prospectus is a part, Karrington has received an
opinion of Wachtell, Lipton, Rosen & Katz, special counsel to Karrington,
addressing the U.S. federal income tax consequences of the merger described
below. This opinion has been rendered on the basis of facts, representations and
assumptions set forth or referred to in the opinion. In rendering the opinion,
Wachtell, Lipton, Rosen & Katz has required and relied upon representations
contained in certificates of officers of Karrington and Sunrise. The Wachtell,
Lipton, Rosen & Katz opinion provides that the following will be material U.S.
federal income tax consequences of the merger:
 
     - the merger will be treated as a reorganization within the meaning of
       Section 368(a) of the Internal Revenue Code;
 
     - each of Sunrise, Buckeye Merger Corporation and Karrington will be a
       party to the reorganization within the meaning of Section 368(b) of the
       Internal Revenue Code; and
 
     - no gain or loss will be recognized by the holders of Karrington common
       shares who exchange all of their Karrington common shares solely for
       Sunrise common stock in the merger, except with respect to cash received
       instead of a fractional share interest in Sunrise common stock.

     In connection with the filing of the registration statement, Sunrise has
received an opinion of Hogan & Hartson L.L.P., counsel to Sunrise, addressing
the U.S. federal income tax consequences of the merger described below. This
opinion has been rendered on the basis of facts, representations and assumptions
set forth or referred to in the opinion. In rendering the opinion, Hogan &
Hartson L.L.P. has required and relied upon representations contained in
certificates of officers of Karrington and Sunrise. The Hogan & Hartson L.L.P.
opinion provides that the following will be material U.S. federal income tax
consequences of the merger:
 
     - the merger will be treated as a reorganization within the meaning of
       Section 368(a) of the Internal Revenue Code;
 
     - each of Sunrise, Buckeye Merger Corporation and Karrington will be a
       party to the reorganization within the meaning of Section 368(b) of the
       Internal Revenue Code; and
 
     - no gain or loss will be recognized by Sunrise, Buckeye Merger Corporation
       or Karrington as a result of the merger.
 
     The obligations of Sunrise and Karrington to complete the merger are
conditioned upon the receipt at the closing of the merger of confirmatory tax
opinions of Hogan & Hartson L.L.P. and Wachtell, Lipton, Rosen & Katz. None of
the tax opinions to be delivered to the parties in connection with the merger as
described in this proxy statement/prospectus is binding on the Internal Revenue
Service or the courts. Neither Sunrise nor Karrington intend to request a ruling
from the Internal Revenue Service with respect to the merger.
 
     Cash received by a Karrington shareholder instead of a fractional share
interest in Sunrise common stock will be treated as received in redemption of
the fractional share interest. A Karrington shareholder should generally
recognize capital gain or loss for U.S. federal income tax purposes measured by
the difference between the amount of cash received and the tax basis of the
fractional share interest. The capital gain or loss would be a long-term capital
gain or loss if the holding period for the fractional share interest is greater
than one year at the closing of the merger.
 
     Information Reporting and Backup Withholding.   Payments in respect of
Karrington common shares may be subject to information reporting to the IRS and
to a 31% backup withholding tax. Backup withholding will not apply, however, to
a payment to a holder of Karrington common shares or other payee if the
shareholder or payee (A) completes and signs the substitute Form W-9 that will
be included as part of the transmittal letter, or (B) otherwise proves to the
satisfaction of Sunrise and the exchange agent that it is exempt from backup
withholding.
 
RESTRICTIONS ON RESALES BY AFFILIATES
 
     The Sunrise common stock to be issued to Karrington shareholders in the
merger will be freely transferable under the Securities Act, except for shares
issued to any person who may be deemed to be an "affiliate" of Karrington within
the meaning of Rule 145 under the Securities Act. Shares of Sunrise common stock
received by
 
                                       53
<PAGE>   63
 
affiliates of Karrington may be resold only in transactions permitted by the
resale provisions of Rule 145 or as otherwise permitted under the Securities
Act. Rule 145 generally requires that, for specified periods, any such sales be
made in compliance with the volume limitations, manner of sale provisions and
current information requirements of Rule 144 under the Securities Act. Persons
who may be deemed to be affiliates of Karrington include individuals or entities
that, directly or indirectly through one or more intermediaries, control, are
controlled by or are under common control with Karrington. Directors, officers
and principal Karrington shareholders may be affiliates of Karrington. Persons
who are not affiliates of Karrington may sell their Sunrise common stock without
restriction.
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
     The following is a description of the steps you must take to perfect
dissenters' rights with respect to the merger. The description is not intended
to be complete and is qualified in its entirety by reference Section 1701.85 of
the Ohio Revised Code, a copy of which is included as Appendix D to this proxy
statement/prospectus. We recommend that you consult with your own counsel if you
have questions with respect to your rights under the statute.
 
     "Dissenters' rights" is your right to dissent from the merger and to have
the "fair cash value" of your Karrington common shares determined by a court and
paid in cash. The "fair cash value" of a Karrington common share is the amount
that a willing seller who is under no compulsion to sell would be willing to
accept and that a willing buyer who is under no compulsion to purchase would be
willing to pay. Fair cash value is determined as of the day prior to the date on
which the vote of the shareholders authorizing the merger is taken. When
determining fair cash value, any appreciation or depreciation in market value
resulting from the proposed merger is excluded. In no event can the fair cash
value of a Karrington common share exceed the amount specified in the demand of
the particular shareholder discussed in 3, below.
 
     To perfect dissenters' rights, you must satisfy each of the following
conditions:
 
         1.   You Must be a Karrington Shareholder on the Record Date.   To be
     entitled to dissenters' rights, you must be the record holder of the
     dissenting shares on March 15, 1999. If you have a beneficial interest in
     Karrington common shares held of record in the name of any other person for
     which you desire to perfect dissenters' rights, you must cause the
     shareholder of record timely and properly to act to perfect such rights.
 
         2.   You Must Not Vote in Favor of the Merger.   Only a shareholder
     whose Karrington common shares are not voted in favor of the merger is
     entitled, if the merger is completed, to be paid the fair cash value of the
     Karrington common shares held of record by the shareholder on March 15,
     1999. A VOTE FOR APPROVAL AND ADOPTION OF THE AMENDED MERGER AGREEMENT AND
     APPROVAL OF THE MERGER CONSTITUTES A WAIVER OF DISSENTERS' RIGHTS.
 
         3.   You Must Serve a Written Demand.   On or before the 10th day
     following the shareholders' vote authorizing the merger, a shareholder who
     wishes to dissent
 
                                       54
<PAGE>   64
 
     must serve a written demand on Karrington for the fair cash value of the
     dissenting shares. The written demand must specify the shareholder's name
     and address, the number of shares of Karrington common shares as to which
     relief is sought and the amount claimed by the shareholder as the fair cash
     value of the shares for which the shareholder is exercising dissenters'
     rights.
 
         4.   You Must Deliver Your Certificates for Legending, if Requested by
     Karrington.   If requested by Karrington, you must submit your certificates
     for dissenting shares to Karrington within 15 days after Karrington sends
     its request. Karrington will then endorse the certificates with a legend
     that demand for fair cash value has been made.
 
         5.   You Must File Petition in Court, if You and Karrington Cannot
     Agree on the Fair Cash Value of Your Dissenting Shares.   If Karrington and
     any dissenting shareholder cannot agree on the fair cash value of the
     dissenting shares, either Karrington or the shareholder must, within three
     months after the service of the written demand by the shareholder, file or
     join in a petition in the Court of Common Pleas of Franklin County, Ohio,
     for a determination of the fair cash value of the dissenting shares.
 
     If you dissent from the merger, your right to be paid the fair cash value
of your shares will terminate:
 
     - if, for any reason, the merger is not completed;
 
     - if you fail to serve a timely and appropriate written demand upon
       Karrington;
 
     - if you do not, upon request of Karrington, make timely and appropriate
       surrender of the certificates evidencing the shares for endorsement of a
       legend that demand for the fair cash value of such shares has been made;
 
     - if your demand is withdrawn with the consent of the directors of
       Karrington;
 
     - if Karrington and you have not agreed upon the fair cash value of your
       dissenting shares and you have not filed or joined in an appropriate
       petition in the Court of Common Pleas of Franklin County, Ohio; or
 
     - if you otherwise fail to comply with the requirements of Section 1701.85
       of the Ohio Revised Code.

                          THE AMENDED MERGER AGREEMENT
 
     The following summary of the material terms of the amended merger agreement
is qualified in its entirety by reference to the merger agreement, which is
attached as Appendix A to this proxy statement/prospectus, and to amendment no.
1 to the merger agreement, which is attached as Appendix B to this proxy
statement/prospectus.
 
CLOSING AND EFFECTIVE TIME OF THE MERGER
 
     The closing of the merger will occur no later than the second business day
after the satisfaction or waiver of the conditions set forth in the amended
merger agreement or at such other time as may be agreed by Sunrise and
Karrington. Under Ohio law, the merger will become effective at the time of
filing of a certificate of merger with the Secretary of State of the State of
Ohio or at such other time as Sunrise and Karrington designate in the
certificate of merger.
 
     If the merger is approved at the special meeting, Sunrise and Karrington
currently expect to close the merger promptly thereafter. However, the closing
of the merger could be delayed if there is a delay in obtaining any required
third party consents. There can be no assurances if or when these consents will
be obtained or that the merger will be completed.
 
MANNER AND BASIS OF CONVERTING KARRINGTON COMMON SHARES
 
     In the merger, each outstanding Karrington common share, except for shares
for which dissenters' rights are exercised as discussed below, will be converted
into the right to receive 0.3333 of a share of Sunrise common stock. In
addition, each share of Sunrise common stock issued in the merger will have
attached to it the right to purchase shares of series C junior participating
preferred stock of Sunrise under its stockholder rights plan. Cash will be paid
instead of fractional shares.
 
     The value of the shares of Sunrise common stock you receive in the merger
will depend on the market price of Sunrise common stock at the time of the
closing of the merger.
 
     If, prior to the closing of the merger, Sunrise or Karrington were to
subdivide or reclassify their stock, then the exchange ratio would be
appropriately adjusted to reflect such action.
 
MANNER OF CONVERTING KARRINGTON STOCK OPTIONS
 
     Each option to purchase Karrington common shares issued under Karrington's
1996 incentive stock plan will be assumed by Sunrise subject to execution and
delivery of a new option agreement by the holder. Each assumed Karrington stock
option will become an option to purchase a number of shares of Sunrise common
stock equal to the product of the exchange ratio and the number of Karrington
common shares subject to the Karrington stock option. The per share exercise
price of the assumed Karrington stock options also will be appropriately
adjusted to reflect the exchange ratio.
 
                                       59
<PAGE>   69
 
EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES
 
     Upon the closing of the merger, Sunrise will enter into an agreement with a
bank or trust company to act as the exchange agent for the Karrington common
shares converted into Sunrise common stock in the merger. As soon as the merger
is completed, the exchange agent will mail to you a letter of transmittal
containing instructions for effecting the surrender of your Karrington common
share certificates in exchange for certificates of Sunrise common stock issuable
in the merger and any cash instead of fractional shares. Upon your surrender of
your Karrington common share certificates to the exchange agent, together with a
properly completed and executed letter of transmittal and other required
documents, you will receive in exchange (A) a certificate or certificates for
the number of shares of Sunrise common stock you have the right to receive, plus
(B) any cash instead of fractional shares of Sunrise common stock to which you
are entitled, subject to applicable withholding. Until so surrendered and
exchanged, your Karrington certificates will represent solely the right to
receive shares of Sunrise common stock and any cash instead of fractional shares
to which you may be entitled under the amended merger agreement.
 
     If Sunrise common stock certificates are issued to a person other than the
person in whose name the corresponding Karrington certificates are registered,
it will be a condition of the exchange that the person requesting such exchange
(A) pay to the exchange agent any required transfer or other taxes or (B)
establish to Sunrise's satisfaction that such tax has been paid or is not
applicable. Unless prohibited by law, you will be entitled to vote, after the
effective time of the merger, at any meeting of Sunrise stockholders the number
of whole shares of Sunrise common stock into which your Karrington common shares
were converted, regardless of whether you have exchanged your Karrington
certificates. However, no dividends or other distributions on Sunrise common
stock with a record date after the merger will be paid to you until you have
surrendered your Karrington common share certificates.
 
     PLEASE DO NOT RETURN YOUR KARRINGTON COMMON SHARE CERTIFICATES WITH THE
ENCLOSED PROXY. INSTEAD, PLEASE HOLD ON TO YOUR CERTIFICATES UNTIL YOU RECEIVE A
LETTER OF TRANSMITTAL FROM THE EXCHANGE AGENT FOLLOWING THE MERGER.

Karrington may, and may authorize and permit its officers, directors, employees
or agents to, furnish confidential or other non-public information and may
participate in discussions and negotiations regarding a competing third party
transaction if Karrington's board of directors (A) is advised in writing by
independent outside counsel to Karrington that the failure to furnish such
confidential or other non-public information or to participate in such
discussions and negotiations would cause the members of the board of directors
of Karrington to breach their fiduciary duties under Ohio law and (B) concludes
based on such advice that the failure to furnish the information or to
participate in the discussions and negotiations would cause the members of the
board of directors of Karrington to breach their fiduciary duties.

     For purposes of the amended merger agreement, a competing third party
transaction, in general, means:
 
     - any merger, consolidation, or similar business combination transaction
       involving Karrington or any of its subsidiaries and a third party other
       than Sunrise;
 
     - any sale or other disposition of 20% or more of the assets of Karrington
       and its subsidiaries, taken as a whole, in one or more transactions;
 
     - any tender or exchange offer for 20% or more of the outstanding shares of
       capital stock of Karrington;
 
     - any person or group acquiring beneficial ownership of 20% or more of the
       then outstanding shares of capital stock of Karrington; or
 
     - any communication to Karrington, or any public announcement, of any
       proposal or agreement to engage in any of the transactions described
       above.
 
CONDUCT OF SUNRISE BUSINESS PENDING THE MERGER
 
     Pending the merger, Sunrise agreed to conduct its business, and cause its
subsidiaries to conduct their respective businesses, to the extent commercially
reasonable, only in the ordinary course and in material compliance with all
applicable laws and regulations. Sunrise also has agreed to use its best
efforts, and to cause its subsidiaries to use their respective best efforts, to
preserve substantially intact their respective business organizations and
assets. In addition, Sunrise agreed, on behalf of itself and its subsidiaries:
 
     - not to intentionally take any action that would prevent the merger from
       qualifying as a tax free reorganization under the Internal Revenue Code;
 
     - not to take any action which could reasonably be expected either to have
       a material adverse effect on Sunrise, or to adversely affect the ability
       of Sunrise to obtain any third party consents required to consummate the
       merger; and
 
     - make available to Karrington a fully secured line of credit in the
       principal amount of up to $16.5 million.
 
     Sunrise also agreed, on behalf of itself and its subsidiaries, not to enter
into any transaction contemplating the acquisition of Sunrise which would
reasonably be expected to materially delay the special meeting or the closing of
the merger unless Sunrise's board of directors (A) is advised in writing by
outside counsel to Sunrise that the failure to enter into the acquisition
transaction would cause the members of the board of directors of Sunrise to
breach their fiduciary duties under the Delaware General Corporation Law and (B)
concludes based on such advice that the failure to enter into the acquisition
transaction would cause the members of the board of directors of Sunrise to
breach their fiduciary duties. In the event of such an acquisition transaction,
Sunrise has agreed to use its best efforts to make adequate provision in the
acquisition for shareholders of Karrington to receive, instead of Sunrise common
stock provided in the amended merger agreement, the same type of securities or
other property that the stockholders of Sunrise would receive in the
acquisition, giving effect to the 0.3333 exchange ratio.

     - by Karrington if:
 
       - there has been a breach of any representation, warranty or agreement by
         Sunrise preventing Sunrise from complying with its obligations under
         the amended merger agreement, and such breach cannot be cured or has
         not been cured within 30 days of the date of the breach;
 
     Karrington must pay Sunrise a termination fee of $5.0 million if:
 
     - either Sunrise or Karrington terminates the amended merger agreement
       because (A) the merger is not completed by June 30, 1999, or September
       30, 1999, if extended as permitted under the amended merger agreement, or
       (B) Karrington shareholders do not approve the amended merger agreement
       and the merger; and prior to any such termination of the amended merger
       agreement a competing acquisition proposal is announced or received by
       Karrington and is completed within one-year after termination of the
       amended merger agreement; or
 
     - Sunrise terminates the amended merger agreement because following the
       announcement or receipt by Karrington of a competing acquisition proposal
       (A) Karrington's board withdraws or changes its recommendation that
       Karrington shareholders approve the amended merger agreement and the
       merger or (B) Karrington does not hold the special meeting; and the
       competing acquisition is completed within one-year after termination of
       the amended merger agreement.
 
     Except as provided in the amended merger agreement regarding the effects of
termination, survival of the representations, warranties and agreements, and
payment of expenses and fees, if the amended merger agreement is terminated as
described above, the amended merger agreement will become void and have no
effect. In addition, if the amended merger agreement is so terminated, there
will be no liability on the part of Sunrise, Buckeye Merger Corporation or
Karrington or any of their respective officers or directors to the other and all
rights and obligations of Sunrise, Buckeye Merger Corporation or Karrington
shall cease. Nothing in the amended merger agreement, however, will relieve
Sunrise, Buckeye Merger Corporation or Karrington from liability for the willful
and material breach of any of its representations, warranties or agreements set
forth in the amended merger agreement.
 
WAIVER AND AMENDMENT OF THE AMENDED MERGER AGREEMENT
 
     At any time prior to the closing of the merger, Karrington, Sunrise and
Buckeye Merger Corporation, may (A) extend the time for the performance of any
of the obligations or other acts of the other parties, (B) waive any
inaccuracies in the representations and warranties of the other party contained
in the amended merger agreement or in any documents delivered under the amended
merger agreement, and (C) waive compliance by the other party with any of the
agreements or conditions contained in the amended merger agreement.
 
     Subject to applicable state law, the amended merger agreement may be
further amended by Karrington, Sunrise and Buckeye Merger Corporation, at any
time before the merger is completed. However, after approval of the amended
merger agreement by
 
                                       68
<PAGE>   78
 
Karrington shareholders, there may not be, without further approval of such
shareholders, any further amendment of the merger agreement that (A) would
reduce the amount or change the type of consideration into which Karrington
common shares will be converted in the merger or (B) by law requires the further
approval by the Karrington shareholders.
 
EMPLOYEE BENEFIT PLANS
 
     Sunrise intends that, within a reasonable time after the merger is
completed, employees of Karrington and Karrington subsidiaries will be eligible
to participate in all employee benefit and compensation plans of Sunrise, on the
same terms as offered to similarly situated employees of Sunrise. Sunrise has
agreed to treat the prior service of employees of Karrington and its
subsidiaries as service to Sunrise for purposes of eligibility, vesting and
benefit accruals under its employee benefit plans but not for purposes of
benefit accruals under any defined benefit or defined contribution pension plan
of Sunrise. In addition, Sunrise has agreed to use its best efforts to cause any
and all pre-existing condition limitations and eligibility waiting periods under
welfare benefit plans of Sunrise to be waived with respect to employees of
Karrington and its subsidiaries and their eligible dependents. To the extent
that these persons have satisfied in whole or in part any annual deductible or
paid any out-of-pocket or co-payment expenses under the applicable plan of
Karrington before the commencement of participation in Sunrise's plan, Sunrise
has agreed to use its best efforts to ensure that they receive credit for the
out-of-pocket or co-payment expenses under the corresponding plan of Sunrise.
Sunrise also has agreed to honor, according to their terms, the employee benefit
agreements previously disclosed by Karrington under the amended merger
agreement.
 
EXPENSES
 
     Subject to the obligation of Karrington to pay a $5.0 million termination
fee under the circumstances described above, the amended merger agreement
provides that Sunrise and Karrington will each pay its own costs and expenses in
connection with the merger. However, Sunrise and Karrington will divide equally
the payment of all printing and mailing costs of the proxy statement/prospectus,
SEC filing fees, "blue sky" filing fees and the filing fee paid in connection
with the Hart-Scott-Rodino Antitrust Improvements Act filing.
 
THE OPTION AGREEMENT
 
     On October 18, 1998, Karrington entered into an option agreement with
Sunrise, in which Karrington granted Sunrise an option to purchase 676,903
Karrington common shares from Karrington, representing 9.9% of the outstanding
shares, at an exercise price of $9.00 per share, payable in cash, Sunrise common
stock or both, at the election of Sunrise.
 
     The option agreement is intended to increase the likelihood that the merger
will be completed. Consequently, it may have the effect of discouraging persons
who might now
 
                                       69
<PAGE>   79
 
or at any other time before the closing of the merger be interested in engaging
in a competing third party transaction with Karrington from considering or
proposing such transaction, even if the third party were prepared to offer to
pay consideration to the Karrington shareholders that had a higher current
market price than the shares of Sunrise common stock to be received by
Karrington shareholders in the merger. The announcement of a competing third
party transaction or receipt of a competing acquisition proposal by Karrington
during the term of the option agreement would cause the option to become
exercisable.
 
     Under the option agreement, Sunrise may not exercise the option if it would
realize upon exercise an aggregate spread value of more than $5.0 million. In
connection with the consummation of any competing third party transaction,
Sunrise may require Karrington to repurchase the option at a purchase price not
to exceed $5.0 million, less the aggregate spread value realized by Sunrise on
any prior exercise of the option.
 
     Karrington has granted Sunrise registration rights with respect to any
Karrington common shares acquired by it upon exercise of the option.
 
     The option agreement will terminate upon the earlier of:
 
     - the closing of the merger;
 
     - one year following termination of the amended merger agreement; or
 
     - 15 months after termination of the amended merger agreement, if a third
       party proposal is made or announced within one year following termination
       of the amended merger agreement.
 
     Because the foregoing is a summary, it may not contain all of the
information that may be important to you. The entire option agreement is
included as an exhibit to the Sunrise Current Report on Form 8-K with the SEC on
October 28, 1998 and is incorporated by reference into this proxy
statement/prospectus.
 
AMENDMENT NO. 1 TO MERGER AGREEMENT
 
     On March 4, 1999, Sunrise, Karrington and Buckeye Merger Corporation
entered into amendment no. 1 to the merger agreement. A copy of amendment no. 1
is attached to this proxy statement/prospectus as Appendix B. Amendment no. 1 to
the merger agreement:
 
     - fixes the exchange ratio at 0.3333 of a share of Sunrise common stock for
       each Karrington common share; the exchange ratio in the original
       agreement was adjustable between 0.3333 and 0.3939 depending on the
       trading price of Sunrise common stock during a 10-day measurement period
       ending three days before the special meeting;
 
     - revises the meaning of "material adverse effect" in the merger agreement
       as applied to Karrington to exclude effects caused by Sunrise providing
       management and consulting services to Karrington;
 
                                       70
<PAGE>   80
 
     - eliminates as a condition to Sunrise's obligation to complete the merger
       the absence of a material adverse effect on Karrington;
 
     - increases from $10 million to $16.5 million the amount of the line of
       credit made available to Karrington by Sunrise for working capital needs,
       including land acquisitions and development projects, prior to the
       closing of the merger; and
 
     - extends the termination date of the merger agreement from March 31, 1999
       to June 30, 1999, subject to extension to September 30, 1999 if all
       necessary third party consents have not been obtained.
 
     In addition to the modifications described above, amendment no. 1 to the
merger agreement also provided that, by separate agreement, the measurement
period in various covenants in the Meditrust loans and leases acquired by
Sunrise in the Meditrust transaction, as described under "Meditrust Transaction"
below, will be extended an additional quarter. This provision also noted that
various covenants in the Meditrust loans and leases which Karrington may be in
default will be waived.
 
MEDITRUST TRANSACTION
 
     As contemplated by the amended merger agreement, Sunrise has acquired from
Meditrust Corporation four mortgages originally held by Meditrust against four
Karrington assisted living residences. As part of this same transaction, Sunrise
also acquired the rights to six assisted living facilities originally leased by
Meditrust to Karrington. These six properties are currently leased to Sunrise by
the entity that provided Sunrise with the financing for the transaction and
acquired the six facilities. Karrington continues to operate the six facilities
under a sublease between Karrington and Sunrise. Sunrise paid approximately
$22.4 million to Meditrust to acquire the four mortgages. The closing of this
transaction satisfied one of the closing conditions to Sunrise's obligations
under the original merger agreement.
 
SUNRISE SERVICES AGREEMENTS
 
     On December 1, 1998, Sunrise Development, Inc., a subsidiary of Sunrise,
and Karrington entered into three development agreements relating to the
development of three facilities: Hamilton, Ohio, Farmington Hills, Michigan and
Edina, Minnesota. Under the development agreements, Sunrise Development, Inc.
agreed to provide development and construction services relating to these three
facilities. In exchange for providing development and construction services,
Sunrise Development, Inc. will receive a $250,000 development fee with respect
to each of the Farmington Hills and Edina facilities, and a $200,000 development
fee with respect to the Hamilton facility. Each development agreement will
remain in effect until the facility covered by the development agreement is
issued a certificate of occupancy.
 
     On January 1, 1999, Sunrise Assisted Living Management, Inc., a subsidiary
of Sunrise, and Karrington entered into a management consulting agreement and a
management services agreement. Under the management consulting agreement,
Sunrise Assisted Living Management, Inc. agreed to assist Karrington in the
management of its
 
                                       71
<PAGE>   81
 
assisted living facilities pending completion of the merger. In exchange for
providing services under the management consulting agreement, Sunrise Assisted
Living Management, Inc. will receive a consulting fee equal to 7% of the
revenues from the facilities. The management consulting agreement has a one-year
term.
 
     Under the management services agreement, Sunrise Assisted Living
Management, Inc. agreed to manage five of Karrington's facilities pending
completion of the merger:
 
     - Farmington Hills, Michigan;
 
     - Edina, Minnesota;
 
     - Eastover, North Carolina;
 
     - Hamilton, Ohio; and
 
     - Tiffin, Ohio.
 
In exchange for providing services under this agreement, Sunrise Assisted Living
Management, Inc. will receive a management fee equal to 7% of the revenues from
the facilities. In addition, the agreement provides for payment of a pre-opening
services fee of $14,000 per month, up to $140,000 in the aggregate, in
connection with unopened facilities. The management services agreement has a
one-year term.

            INFORMATION ABOUT SUNRISE AND BUCKEYE MERGER CORPORATION
 
GENERAL
 
     Sunrise.   At December 31, 1998, Sunrise operated 77 assisted living
facilities in 13 states with a capacity of over 6,630 residents. Sunrise owns or
has ownership interests in 66 of these facilities and manages the other 11
facilities for third parties. In addition, three of the 77 facilities are
subject to long-term ground leases. Sunrise currently is constructing another 23
assisted living facilities with a resident capacity of 2,160. Sunrise has also
entered into contracts to purchase 46 additional development sites, nine of
which are zoned by the applicable municipal authority to permit the development
of an assisted living facility on the property. In addition, Sunrise has entered
into contracts to lease two additional sites under long-term ground leases.
Sunrise also is pursuing additional development opportunities and plans to
acquire additional facilities as market conditions warrant. Sunrise also
operates two skilled nursing facilities owned by a third party.
 
     Sunrise provides assistance with the activities of daily living and other
personalized support services in a homelike residential setting for elderly
residents who cannot live independently but who do not need the level of medical
care provided in a skilled nursing facility. Sunrise also provides additional
specialized care and services to residents with low acuity medical needs and
residents with Alzheimer's disease or other forms of dementia. By offering this
full range of services, Sunrise is able to accommodate the changing needs of
residents as they age and develop further physical or cognitive frailties.
Unlike assisted living facilities, skilled nursing facilities provide 24 hour
skilled nursing care, supervised by a registered nurse. Skilled nursing care
includes directed resident care, therapeutic care, therapeutic diets and other
Medicare-defined long-term care services.
 
     At December 31, 1998, Sunrise's total assets were $683.4 million, its total
liabilities were $453.9 million and its stockholders' equity was $227.7 million.
 
     Sunrise was incorporated in Delaware in 1994 to combine various activities
relating to the development, ownership and operation of the Sunrise assisted
living facilities held by predecessor entities. Sunrise's executive offices are
located at 9401 Lee Highway, Fairfax, Virginia 22031, and its telephone number
is (703) 273-7500.
 
     Buckeye Merger Corporation.   Buckeye Merger Corporation was recently
formed by Sunrise as a wholly owned subsidiary to accomplish the merger. The
separate corporate existence of Buckeye Merger Corporation will end upon the
completion of the merger.
 
MANAGEMENT AND ADDITIONAL INFORMATION
 
   
     Information relating to executive compensation, voting securities and the
principal holders of voting securities, relationships with directors, executive
officers and principal stockholders of Sunrise and related transactions and
other related matters as to Sunrise is incorporated by reference or set forth in

                          INFORMATION ABOUT KARRINGTON
 
GENERAL
 
     In 1989, Richard R. Slager and Alan B. Satterwhite formed DevelopMed
Associates, Inc. for the purpose of developing an assisted living residence
business. In 1991, DevelopMed entered into a strategic alliance with JMAC, Inc.,
an investment company owned by John H. McConnell and John P. McConnell, the
founder and the chief executive officer, respectively, of Worthington
Industries, Inc. In connection with this alliance, DevelopMed and JMAC
Properties, Inc., a wholly owned subsidiary of JMAC, formed Karrington's
predecessor, Karrington Operating Company, an Ohio general partnership.
 
     Karrington was incorporated in April 1996.   Initially, 66 2/3% of
Karrington's common shares were issued to JMAC in exchange for all of its shares
of JMAC Properties and 33 1/3% of Karrington's common shares were issued to the
shareholders of DevelopMed in exchange for all of their shares of DevelopMed. As
a result, Karrington Operating Company became a subsidiary of Karrington.
 
     Karrington's market strategy is to enter middle- to upper-income markets
which have well-established populations of persons 75 years of age and older
and/or persons in the 45 - 60 years of age caregiver stage. As of December 31,
1998, Karrington had developed 50 residences in its target markets, 40 of which
were open and 10 of which were under construction and scheduled to open in 1999
or 2000. These 50 residences are located in Ohio, Pennsylvania, Illinois,
Minnesota, North Dakota, Iowa, Indiana, Colorado, North Carolina, Michigan and
New Mexico. Karrington has sites for an additional eight residences under
contract in these states, as well as in Alabama, Mississippi and Texas.
 
SERVICES AND OPERATIONS
 
     Services Provided.   Karrington provides assistance to elderly or frail
individuals with limited medical needs and may provide higher levels of personal
assistance for special need residents. Most Karrington residents have some
disability associated with aging, such as dementia, Alzheimer's disease,
arthritis, nutritional problems, incontinence, strokes or other disorders, and
need assistance with two or more activities of daily living. Residents' needs
generally fall into one or more of the following categories:
 
     - requiring physical support or assistance with activities of daily living;
 
     - requiring assistance, reminders and cueing due to some cognitive
       impairment; and
 
     - requiring socialization and interaction with others.
 
     Residents generally pay a daily suite rental rate under a resident
agreement which is renewable annually and cancelable with 30 days notice. The
daily suite rental rate ranges from $36 to $175 per day, depending on unit size,
location, number of occupants and level of care required. Karrington's average
basic daily suite rental rate is approximately $86. The wide range of rates
offered by Karrington allows Karrington to accommodate persons of varying
financial resources. Medication administration and various levels of
                                       74
<PAGE>   84
 
extended care services, which depend on the degree of frailty, add to the basic
care rate. Additional charges may be incurred for other services such as hair
care and special diets. Currently, approximately 91% of all resident revenues
are from private pay sources.
 
     Karrington's basic care program is provided to all residents at no
additional cost. This basic care program includes:
 
     - limited assistance with daily living;
 
     - three meals per day served in a common dining room;
 
     - 24-hour security;
 
     - emergency call systems in each unit and living area;
 
     - assistance with arranging outside services such as physician care,
       various therapy programs and other medical services;
 
     - personal laundry services;
 
     - housekeeping services; and
 
     - social and recreational activities.
 
     In addition to the basic care program, non-Alzheimer's residents may be
included in the extended care program, which assists residents who require more
frequent or more intensive assistance or care. Prior to entering a Karrington
residence, and periodically during their stay, individuals' needs are assessed
to determine the level of extended care services required, and an individual
care plan is designed. Karrington's experience is that most of its
non-Alzheimer's residents require some extended care services or require
medication administration at an average cost of $15 per day.
 
     Karrington's Alzheimer's and other cognitive disorder programs are provided
in each prototype residence on a designated "special care" floor or wing.
Karrington also develops residences designed specifically for Alzheimer's
disease care. Trained staff provide special care programs for cognitively
impaired residents, and each is charged additional daily fees for this added
support. Programs include added assistance, stimulation, special activities,
intervention and therapeutic programs that are developed and supported by
physicians specializing in dementia care that consult with Karrington.
 
     Staffing.   Each residence, excluding cottages, has an administrator and a
seven-person management team. The resident care coordinator supervises all
resident support staff and care plans. A registered nurse/wellness director is
responsible for all wellness programs, as well as medication and other ancillary
support programs. The director of administration is responsible for general
administrative duties. The marketing director, activities director, chef and
environmental services director complete the management team. Each cottage model
has an administrator, an associate administrator and a wellness director.
Residence management teams report to a regional director responsible for the
operation of several residences. Regional directors provide support, oversight
and mentoring to each residence's staff.
 
                                       75
<PAGE>   85
 
     Staffing models are used to determine appropriate personnel levels.
Screening is used to help select staff with "care providing" characteristics.
For each residence, regardless of size, services are provided on a 24 hour per
day basis with an overall average 1:12 staff to resident ratio. The staffing
ratio for dementia care is 1:7 at all times. The average daytime staffing ratio
for all residences is 1:9. The largest percentage of care staff includes trained
staff members who are responsible for providing support and care to residents
and licensed nurses who coordinate care assessments and implement treatment and
therapies.
 
     Karrington maintains competitive compensation programs, including
incentives and quarterly profit sharing, which it believes help attract and
retain excellent employees. Karrington believes that the combination of proper
interviewing, selection methods and review, training and appropriate incentives
significantly reduces hiring and retraining costs and allows for a more stable,
long-term work force. All management team members participate in a recruitment
and development program called the Predictive Index(R). The Predictive Index(R)
is a third-party program to determine key criteria and personal attributes that
Karrington believes are important to the proper placement of staff and
management.
 
     Training and Quality Assurance.   Karrington provides its personnel with an
extensive and innovative training program. Before contact with residents, an
employee must complete a 40 hour curriculum covering all aspects of Karrington's
operation, from housekeeping schedules to coping with death and dying. New
employees are then paired with a mentor who supervises his or her work until the
supervisor has certified that the employee has completed all aspects of the
training program. This certification process generally takes about a week. Each
new employee is reviewed for performance at the end of a 90-day probationary
period. Karrington provides continuing education for all employees to enhance
the quality of care provided to residents.
 
     Karrington has structured a comprehensive quality assurance program
intended to maintain standards of care established for each residence. Under
Karrington's quality assurance program, the care and services provided at each
residence are monitored by the professional services staff which reports
directly to Karrington's senior management. The quality assurance team works
with residence management teams to assure that all staff members are trained,
that operational policies and procedures are followed, and that all state and
federal standards are met while achieving the stringent requirements of
Karrington. Karrington's quality assurance program helps support compliance with
federal and state regulations and requirements for licensing. Karrington has
also developed a quality of service program which includes periodic surveys and
follow-up with all current and former residents and responsible parties.
 
ARCHITECTURAL DESIGNS
 
     Recognizing that not all seniors share the same acuity at various income
levels, Karrington has created three standard models of residence, an evolution
of Karrington's original prototype mansion-style residence. Along with creating
three standard models,
 
                                       76
<PAGE>   86
 
Karrington has branded, or named, its residential products to help build
Karrington's national identity.
 
     Karrington's original mansion-style residence, now known as K1 or the
Karrington model, is a freestanding, mansion-style building in any of a variety
of exterior styles. Located in established upper-income communities, the K1
replaces the original 53-unit prototype. The K1 prototype averages 72 units and
approximately 50,000 square feet and is generally built on a 2.5 to 4 acre site.
 
     Karrington's one-story model, K2, is a small-town solution to high-quality
assisted living. The K2 model residence averages 48 units with a designed
capacity of 61 residents. The K2 offers residents of smaller and rural
communities access to the skilled and caring professionals, unique products and
services, and dignified environments that enable Karrington residents to
age-in-place gracefully.
 
     A typical resident unit consists of a bedroom, bathroom with shower,
lavatory and toilet, vestibule with kitchenette and closet. A variety of unit
sizes and configurations allows resident choice in accommodations. Unit size
ranges from approximately 250 square feet to over 450 square feet and there are
both single room units and two room units. Units are marketed for single
occupancy, companion occupancy with two residents sharing the same bedroom, and
doubles and suites containing a living room and a bedroom.
 
     Approximately 45-50% of each of the K-1 and K-2 models is devoted to common
areas and amenities. The interior design promotes a home-like environment while
permitting the effective provision of resident care programs and promoting
resident independence. The individual resident suites are clustered on each
floor to resemble a neighborhood, with a variety of suite floor plans of one or
two rooms and varying square footage. Each floor has a quiet area resembling a
library or den and an active area designed to support activity programs and
interaction among residents, staff and families. The main floor usually includes
the main dining room, private dining rooms, administrative offices, a library, a
living or family room, and ice cream parlor and a year-round sun porch. Also
included are public restrooms, outside porches, a foyer and a formal entryway
with grand staircase and central elevator. On other floors in each residence are
located a resident laundry room, a wellness center, a bathing spa area, employee
break rooms, a beauty salon and activity areas. The special care floor also
includes a separate resident kitchen and dining area.
 
     Karrington's third residential model is the outgrowth of Karrington's May
1997 acquisition of Kensington Management Group, Inc. of Golden Valley,
Minnesota. Operating innovative Alzheimer's care communities, now known as
Karrington Cottages, or KC, Karrington provides residential Alzheimer's care and
other programs under the medical direction of geriatric and dementia
specialists. The Karrington Cottage prototype model is 20 units with 36 beds.
 
     Karrington believes all three basic building plan designs provide it with
flexibility in adapting the model to a particular site and local zoning
requirements.

DEVELOPMENT
 
     Karrington's development personnel research and identify potential markets,
primarily in major metropolitan areas and their surrounding suburban
communities, and select sites for development within such markets. In evaluating
a market, Karrington considers a number of factors, including:
 
     - population, income and age demographics;
 
     - traffic count;
 
     - site visibility;
 
     - residential and commercial characteristics;
 
     - probability of obtaining zoning approvals;
 
     - proximity of various competitors;
 
     - estimated market demand; and
 
     - the potential to achieve economies of scale in a specific market by
       concentration of its development and operating activities.
 
     The principal stages in the development process are (a) strategic market
selection and assessment, (b) site selection and contract signing, (c) zoning
and site plan approval, (d) architectural planning and design, (e) contractor
selection and (f) construction and licensure. Once a market has been identified,
site selection and contract signing typically take three months. Zoning and site
plan approval generally take three to nine months and are typically the most
difficult step in the development process as a result of Karrington's selection
of sites in established communities which frequently require site rezoning.
Architectural planning and design and contractor selection often occur during
the zoning process but can prolong the start of construction. Residence
construction generally takes 12 months. After a residence receives a certificate
of occupancy and appropriate licenses, residents usually begin to move in
immediately. Karrington's experience indicates that new residences typically
reach a stable level of occupancy of over 90% within 13 months, but there can be
no assurance that these results will be achieved in new markets. Karrington
estimates that total capitalized cost to develop, construct and open a
Karrington K-1 or K-2 model residence, including land acquisition and
construction costs, ranges from approximately $5.0 million to $11.0 million, an
average cost per unit of approximately $110,000. The cost of any particular
residence may vary considerably based on a variety of site-specific factors.
 
MARKETING
 
     Karrington's marketing approach emphasizes consumer education and awareness
directed to potential residents and family members. The adult children of
residents tend
 
                                       78
<PAGE>   88
 
to be significant decision-makers in the selection of the assisted living
option. Other significant referral sources include:
 
     - hospital discharge planners;
 
     - physicians;
 
     - churches;
 
     - social service agencies focused on the elderly;
 
     - nursing facilities in the area;
 
     - home health agencies;
 
     - social workers;
 
     - legal advisors;
 
     - other health care providers; and
 
     - families of existing residents.
 
Telephone directory advertising, media products and informal "networking" are
directed by Karrington toward educating decision-makers and other referral
sources in a community. The marketing personnel in Karrington's corporate office
develop the overall strategy in each market as well as media materials,
databases, direct mail, signage and community outreach activities. Each
residence has a marketing director responsible for generating and following-up
leads, coordinating referral activities and providing tours, counseling and
caregiving advice for potential residents and their families with respect to
Karrington's residences and services.
 
     Marketing activities begin during the development stage of a residence,
after Karrington has obtained site control. These activities continue with
increased emphasis when an information center opens for a specific residence
approximately six to nine months prior to opening.
 
REGULATION
 
     Karrington's assisted living residences are subject to regulation and
licensing by state and local health and social service agencies and other
regulatory authorities. Requirements vary from state to state. These
requirements address:
 
     - personnel education, training and records;
 
     - facility services, including administration of medication and the
       provision of limited nursing services;
 
     - physical plant specifications;
 
     - furnishing of residents' units;
 
     - food and housekeeping services;
 
     - emergency evacuation plans; and
 
     - residents' rights and responsibilities.
 
                                       79
<PAGE>   89
 
Assisted living residences also are subject to state or local fire and building
codes and food service licensure requirements. Like other health care
residences, assisted living residences are subject to periodic survey or
inspection by governmental authorities. From time to time in the ordinary course
of business, Karrington receives survey reports. Karrington reviews such reports
and takes appropriate corrective action if deficiencies are noted. Inspection
deficiencies are resolved through a plan of correction, although the reviewing
agency typically is authorized to take action against a licensed facility where
deficiencies are noted in the survey process. Such action may include imposition
of fines, imposition of a provisional or conditional license or suspension or
revocation of a license or other sanctions.
 
     Health care is an area of extensive and frequent regulatory change. The
assisted living model for long-term care is relatively new. Accordingly, the
manner and extent to which it is regulated at the federal and state levels is
evolving. Changes in the laws or new interpretations of existing laws may have a
significant effect on methods and costs of doing business. Karrington is
actively involved in monitoring regulatory and legislative changes affecting the
assisted living industry and participates with industry organizations to
encourage improvements to existing laws and regulations.
 
     The success of Karrington will depend in part upon its ability to satisfy
applicable regulations and requirements and to procure and maintain required
licenses as the regulatory environment for assisted living evolves. Karrington's
operations also could be adversely affected by future regulatory developments
such as mandatory increases in the scope and quality of care to be offered to
residents and revisions to licensing and certification standards.
 
     Karrington currently is not a Medicare provider. Under some state licensure
laws, and for the convenience of its residents, some of Karrington's assisted
living residences maintain contracts with several health care providers and
practitioners through which health care providers make their health care
products or services available to residents. These contract parties include
pharmacies, visiting nurses, social service and home health organizations. Some
of the services furnished by these contract parties may be covered by the
Medicare programs.
 
COMPETITION
 
     Karrington's competition comes from a variety of sources. As a provider of
care and services to elderly or frail individuals, Karrington competes with
companies such as home health care agencies, retirement communities, skilled
nursing facilities and convalescent centers, as well as other assisted living
facilities. In each of these cases, however, Karrington's ability to provide a
non-institutional environment for persons who need higher levels of care
enhances its competitive strength.
 
     The assisted living industry is highly fragmented. Although some
competitors are significantly larger, there are no one or more dominant
companies in the assisted living segment. In a recent industry report, it is
estimated that there are approximately 770,000 total assisted living beds
currently available, and that the 25 largest owners of assisted
 
                                       80
<PAGE>   90
 
living properties has 180,446 or only 23% of those currently available. The
largest individual owner has only 3% of the total assisted living beds currently
available.
 
     Because little public funding exists for assisted living, most residents
are private pay. Within the assisted living industry, providers compete by
price, quality of care, service packages and quality of life. Karrington
believes that its combination of buildings, furnishings, care, services and
other amenities enables it to compete effectively.
 
PROPRIETARY INFORMATION
 
     Karrington is the registered owner of the service mark "Karrington
Communities(R)." Karrington believes this mark is of material importance to its
business.
 
EMPLOYEES
 
   
     As of March 31, 1999, Karrington had approximately 1,800 employees,
including approximately 350 employed by Karrington's joint ventures. None of
Karrington's employees are represented by a union or covered by a collective
bargaining agreement. Karrington has experienced no work stoppages and considers
its relationship with its employees to be good.

LEGAL PROCEEDINGS
 
     Karrington is a defendant in litigation pending in the Franklin County
Court of Common Pleas, Columbus, Ohio. On May 29, 1998, Lou Buren, formerly vice
president-marketing of Karrington, filed suit against Karrington for wrongful
termination of employment. The suit originally sought damages of approximately
$450,000. On March 3, 1999, Mr. Buren filed an amended complaint joining
Karrington Operating Company, a subsidiary of Karrington, and two Karrington
officers as defendants and increasing the amount of damages sought to
approximately $6.7 million. Karrington denies Mr. Buren's claims and intends to
vigorously defend itself.

                KARRINGTON MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
     Karrington is an operator and owner of licensed, assisted living residences
which provide quality, professional, personal and health-care services,
including an emphasis on Alzheimer's care, for individuals needing assistance
with activities of daily living. These activities include bathing, dressing,
meal preparation, housekeeping, taking medications, transportation, and other
activities that, because of the resident's condition, are difficult for
residents to accomplish in an independent living setting. Karrington offers its
customers a dignified residential environment focused on quality of life.
Karrington also provides development, support and management services to its
joint venture residences. As of December 31, 1998 Karrington had 40 residences,
including joint ventures, open in 11 states with a capacity of 2,320 residents.
Six additional residences were under construction while four others were
complete and being readied for occupancy. These ten residences have a capacity
of 624 residents.
 
     Karrington derives its revenues primarily from: (a) resident fees for the
delivery of basic assisted living care services, which accounted for 80% of
total revenues in 1998; (b) resident fees for extended and special needs care
services which accounted for 9% of total revenues in 1998; and (c) community fee
revenue which accounted for 8% of total revenues in 1998. Resident fees include
revenue derived from basic assisted living care, community fees, extended and
special needs care and other sources. Community fees are one-time fees generally
payable by a resident upon admission. Extended and special needs care are paid
by residents who require personal care in excess of services provided under the
basic care program.
 
     The following table sets forth specified information regarding Karrington
residences as of December 31, 1998:

</TABLE>
 
RESULTS OF OPERATIONS
 
     The following significantly impacts results of operations:
 
OCCUPANCY OF RESIDENCES IN OPERATION
 
     Karrington classifies residences that have been open at least 12 months or
have achieved an occupancy percentage of 95% or above to be stabilized
residences. Karrington's ability to maintain a high occupancy percentage in
stabilized residences has a significant impact on results of operations. This is
because many costs are fixed and a
 
                                       84
<PAGE>   94
 
decline in occupancy below approximately 70-75% means that the residence is not
contributing net profits to Karrington's results of operations.
 
RESIDENCES IN THE FILL-UP PHASE
 
     The number of residences moving from the construction to the fill-up phase
can have a significant impact on operations. It typically takes 13 months for a
new residence to reach an occupancy level of 90%. During that time, the
residence is incurring significant losses because of fixed occupancy costs and
payroll. Fixed occupancy costs include interest, depreciation, rent and real
estate taxes. The speed at which a residence can achieve stabilization can have
a significant effect on operations. In periods where the percentage of
residences in the fill-up phase is significant, as is the case for 1998,
operating losses will be significant and will continue until Karrington reaches
a base of stable homes that absorb losses generated by residences in the fill-up
phase. Based on past experience, we expect that all residences currently in the
fill-up phase will reach stabilization in late 1999. Summarized below is a
breakdown of open consolidated stable residences and open consolidated
residences in the fill-up phase for the periods indicated:

</TABLE>
 
GENERAL AND ADMINISTRATIVE COST
 
     Karrington requires a particular level of general and administrative
spending to operate. General and administrative spending has increased
significantly over the past three years as Karrington has incurred costs to
support the growth of its business. However, this spending is not variable in
that it does not increase proportionately with the number of residences in
operation. Consequently, as Karrington grows, general and administrative costs
as a percent of revenues should decrease.
 
LEASE VS. MORTGAGE FINANCING
 
     Karrington initially followed a plan of ownership using mortgage financing.
This approach results in depreciation and interest charges that tend to be
highest in the early years of operation. During 1998, Karrington opened five
residences under operating leases. Karrington has also entered into
sale/leaseback transactions in 1998 on six additional residences that were
originally owned and financed under mortgages. Lease financing is advantageous
from a results of operations perspective because rent expense under operating
leases is lower than depreciation and interest under traditional ownership and
mortgage arrangements.
 
                                       85
<PAGE>   95
 
RESIDENCES UNDER CONSTRUCTION
 
     The number of residences under construction impacts the results of
operations due to the impact on capitalization of internal development and
construction department costs, as well as interest, that are capitalized as part
of construction. Fewer residences under development or construction mean less
cost is capitalized, which adversely impacts the results of operations.
 
UNUSUAL CHARGES
 
     The 1997 charge was primarily due to Karrington's decision to abandon some
of its projects in development.

consolidated statements of operations as a percentage of total revenues:

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997
 
     Total revenue increased $15.6 million, or 81%, to $34.8 million in 1998
from $19.2 million in 1997 primarily due to the opening of new residences ($8.0
million), the acquisition of Kensington Management Group, Inc. and affiliates on
April 30, 1997 ($3.8 million) and the increased occupancy of residences in the
fill-up phase in 1997. Average occupancy for the stabilized residences in 1998
and 1997 was 89%.
 
     Residence operating expenses increased $14.6 million, or 107%, to $28.3
million in 1998 from $13.7 million in 1997. As a percentage of residence
operating revenues, residence operating expenses increased from 74% in 1997 to
83% in 1998 which resulted in a residence net operating income margin of 26% in
1997 and 17% in 1998. The decrease in net operating income resulted from
start-up losses associated with residences open less than one year (18
residences in 1998 vs. 7 residences in 1997).
 
                                       86
<PAGE>   96
 
     General and administrative expenses increased $2.1 million, or 46%, to $6.5
million in 1998 from $4.4 million in 1997 primarily due to the acquisition of
Kensington ($.2 million), a provision for terminated projects of $.9 million
largely due to the abandonment of one site and the third quarter sale of two
additional sites and an increase in uncapitalized construction and development
costs of $.8 million. Karrington expects general and administrative expenses
will continue to decrease as a percentage of total revenues due to anticipated
economies of scale resulting from an increase in the number of open residences.
 
     Rent expense increased $3.7 million to $4.0 million in 1998 due to the
opening of five leased residences in 1998 and the sale of six residences in
sale-leaseback transactions in the second quarter of 1998.
 
     Depreciation and amortization increased $2.5 million, or 95%, to $5.2
million in 1998 from $2.7 million in 1997 primarily due to the opening of new
residences ($2.4 million), residences open for only a partial period in 1997
($.3 million) and the acquisition of Kensington ($.3 million), offset by lower
depreciation and amortization resulting from the sale of six residences in
sale-leaseback transactions in the second quarter of 1998.
 
     Interest expense increased $3.2 million, or 114%, to $5.9 million in 1998
from $2.7 million in 1997 primarily due to the opening of new residences and
residences open for only a partial period in 1997 ($1.9 million), the
acquisition of Kensington ($.9 million), a decrease in capitalized interest ($.8
million) and the increased use of Karrington's lines of credit ($.5 million),
offset by lower interest expense resulting from residences sold in
sale-leaseback transactions in the second quarter of 1998.
 
     The equity in net loss of unconsolidated entities increased due to four
joint venture residences in the fill-up phase during 1998 compared to two joint
venture residences in the fill-up phase during 1997. See Note 2 to Consolidated
Financial Statements for discussion on the minority interest of consolidated
entity.
 
     The tax provision recorded in 1998 represents a current state tax liability
resulting from tax gains primarily associated with sale/leaseback transactions.
No deferred tax benefit was recorded in 1998 due to limitations associated with
the recognition of operating loss carryforwards and other tax assets.
 
     The net loss for 1998 compared to the net loss for 1997 increased
substantially from $5.7 million to $15.5 million. The increase in the net loss
is primarily attributable to the significant increase in the number of
residences in the fill-up phase and increased general and administrative costs
necessary to support Karrington's growth. The increase in net loss of $9.8
million is attributable primarily to residences opened in 1998 and the
Kensington acquisition, which generated combined incremental losses of more than
$8.3 million, and the increase in general and administrative costs of $2.1
million.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
     Total revenue increased $9.6 million, or 100%, to $19.2 million in 1997
from $9.6 million in 1996 primarily due to the growth in resident revenues.
Resident revenues
 
                                       87
<PAGE>   97
 
increased $9.6 million, or 107%, primarily due to the acquisition of Kensington
on April 30, 1997 ($5.2 million), opening of new residences in 1997 ($1.3
million) and a full year of operations of residences opened or in fill-up in
1996.
 
     Residence operations expense increased $7.2 million, or 111%, to $13.7
million in 1997 from $6.5 million in 1996. As a percentage of residence
operating revenues, residence operations expense increased to 73.8% in 1997 from
72.4% in 1996. This increase is primarily attributable to an increase in the
number of residences in the fill-up phase as operations expenses are
historically higher as a percent of operating revenues during the first year of
operation of a residence.
 
     General and administrative expenses increased $1.6 million, or 59.9%, to
$4.4 million in 1997 from $2.8 million in 1996, primarily due to increased
compensation, payroll taxes and related benefits as a result of hiring
additional management and staff at Karrington's headquarters as a result of
Karrington's growth plans. Karrington expects the rate of increase in its
general and administrative expenses will decrease as new personnel needs have
been reduced by recent hires. In addition, Karrington expects its general and
administrative expenses will decrease as a percentage of its total operating
revenues due to anticipated economies of scale resulting from Karrington's
development program.
 
     Depreciation and amortization increased $1.3 million, or 94.6%, to $2.7
million in 1997 from $1.4 million in 1996 primarily due to the opening of new
residences in 1997 and 1996.
 
     See Note 2 to Consolidated Financial Statements for discussion on the
unusual charges in 1997.
 
     Interest expense increased $1.4 million, or 116%, to $2.7 million in 1997
from $1.3 million in 1996 primarily due to the opening of new residences in 1997
and 1996.
 
     The net loss for 1997 compared to the net loss for 1996 increased
substantially from $2.6 million to $5.7 million. The increase in the net loss is
primarily attributable to the significant increase in the number of residences
in the fill-up phase and increased general and administrative costs necessary to
support Karrington's growth. The increase in net losses of $3.0 million is
attributable primarily to residences opened or acquired in 1997, which generated
losses of approximately $2.5 million for 1997, and the increase in general and
administrative costs of $1.7 million. These losses were offset by increased net
profits of residences in the fill-up phase in 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Karrington has financed its initial growth through a combination of
mortgage financing, sale/leasebacks, a development bond, subordinated borrowings
from JMAC, bank lines-of-credit, equity contributions and proceeds from the
initial public offering in 1996. Karrington's mortgage and construction mortgage
financings mature in the next one to thirteen years, bear interest at various
fixed and fluctuating rates and are secured by substantially all of the assets
of Karrington. Karrington expects to refinance such amounts as they mature.
 
                                       88
<PAGE>   98
 
     Net cash used in operations has increased from $.9 million in 1996 to $7.7
million in 1998. This continued increase reflects the operating losses
associated with newly opened residences and increased general and administrative
costs as part of the Company's rapid growth plan over this period. As discussed
previously, residences in the fill-up phase generate operating losses until
reaching 70-75% occupancy. The Company's mix of residences in the fill-up phase
has increased and represent 55% of all open residences in 1998. Cash used by
operations will continue in the near future until such time as residences
currently in the fill-up phase become stable and generate enough net profits to
absorb losses from start-up residences.
 
     Net cash used in investing activities totaled $1.9 million, $53.6 million
and $27.7 million for the years ended December 31, 1998, 1997 and 1996,
respectively. Excluding cash generated from sale and sale/leaseback transactions
of $41.6 million, cash used by investing activities totaled $43.6 million in
1998. These expenditures related primarily to the Company's construction and
development activities.
 
     Net cash provided by financing activities totaled $8.0, $49.6 million and
$40.8 million for the years ended December 31, 1998, 1997 and 1996,
respectively. Cash provided from financing activities from 1996 through 1998
included $90.7 million from mortgages, $10.3 million from lines of credit, $7.5
million from JMAC and $27.5 million related to the Company's initial public
offering in 1996. During the same period, the Company repaid approximately $36.2
million of mortgages. Net cash provided by financing activities was used
primarily to fund the Company's construction and development activities.
 
     Karrington has a line of credit totaling $5 million, all of which was
outstanding at December 31, 1998. Interest is payable monthly and, at
Karrington's option, accrues at the bank's prime rate or LIBOR rate plus .75%.
 
     On April 30, 1997, Karrington entered into a $27.6 million promissory note
in conjunction with its acquisition of Kensington. Interest accrues at 10% and
is payable monthly. The amount outstanding under the agreement was approximately
$19.9 million as of December 31, 1998. The remaining funds were to be disbursed
in two phases prior to April 30, 1999, subject to certain Rochester, Minnesota
cottages and other Kensington properties achieving minimum debt service coverage
ratios. Karrington's decision not to open four of the remaining Rochester
cottages until later in 1999 prevents Karrington from accessing $5.9 million of
the remaining $7.7 million of additional funds. Karrington is currently in the
process of negotiating the extension that will allow Karrington to achieve the
necessary fill-up to meet the required minimum debt service coverage ratios.
 
     In October 1997, Karrington entered into a $10.3 million construction loan
agreement for the development and construction of three assisted living
residences. Interest is payable monthly and accrues at the bank's prime rate
plus 1 1/2% during construction. In October 1999, Karrington may elect, at its
option, to convert the construction loan into a term loan maturing in October
2004. Interest payments under the term loan would accrue at prime plus 1 1/2% or
an amount equal to 3.0% over the yield at the time on five-year U.S. Treasury
notes. Karrington is required to maintain minimum net worth and current ratio
amounts and, if the term loan is elected, to
                                       89
<PAGE>   99
 
maintain debt service coverage ratios with respect to individual residences. At
December 31, 1998, Karrington was in violation of the net worth, tangible net
worth and current ratio covenants, which the lender has waived through the end
of 1999. As of December 31, 1998, there was $7.4 million outstanding under this
agreement.
 
     In early 1998, Karrington entered into construction loan agreements
totaling $20.1 million. Interest is payable monthly and accrues at LIBOR plus
2.75% or prime plus  1/2%. In December 2000, Karrington may elect, at its
option, to extend the agreements up to two additional years. As of December 31,
1998, there was $19.3 million outstanding under these agreements.
 
     See Note 6 to the Consolidated Financial Statements for further information
on Karrington's long-term obligations and notes payable.
 
     Karrington currently plans to open approximately 16 new Karrington and
jointly-owned residences in 1999 and the second quarter of 2000. Karrington has
opened one of these residences in 1999. In addition, Karrington has 4 cottage
homes completed and being readied to open, has 5 residences under construction
and has obtained zoning approval for the remaining 6 residences. The 16 planned
openings do not include any cottage homes beyond the 4 cottages completed and
ready to open on the Rochester, Minnesota campus. Karrington is currently
evaluating potential and existing relationships with hospitals and clinics in
order to evaluate additional alternative, broader uses of its cottage model. As
a result of these evaluations, Karrington's final plan for 1999 cottages will be
announced at a later date. Karrington has been, and will continue to be,
dependent on third party financing for its acquisition and development program.
Karrington estimates that newly developed residences will generally range in
cost from $5.0 to $11.0 million, with the development cycle taking up to 24
months from site identification and zoning through construction and residence
opening. There can be no assurance that financing for Karrington's development
program will be available to Karrington on acceptable terms, if at all.
Moreover, to the extent Karrington opens properties that do not generate
positive cash flow, Karrington may be required to seek additional capital for
working capital and liquidity purposes.
 
     Karrington has existing financing in place in the form of loans or leases
for the four residences that are currently completed and ready to open and three
of the residences under construction. Additional financing will be required for
the three additional residences under construction, to develop and construct the
residences not currently under construction and to refinance certain existing
indebtedness. Karrington has about $6.4 million invested in six projects staged
for construction starts during early 1999 that are now awaiting construction or
lease financing. Investments in future projects will be limited until future
financing commitments are obtained. In the second quarter of 1998, Karrington
completed sale/leaseback transactions for six residences. These sale/ leaseback
transactions generated approximately $13 million in net proceeds after
associated mortgage repayment. Karrington has not been pursuing permanent
financing for the three residences under construction pending the outcome of the
proposed merger with Sunrise. However, Karrington is continuously evaluating its
financing alternatives,
 
                                       90
<PAGE>   100
 
including traditional mortgages, sale/leaseback transactions and other forms of
off-balance sheet financing.
 
     Karrington has funds available for working capital needs under project
financings currently in place. At this time, Karrington expects to draw on six
project mortgage and lease financings to support its working capital needs in
the first and second quarters of 1999.
 
     In addition, in the third quarter of 1998 Karrington sold two parcels of
land in California for a total of $3.5 million. The net proceeds to Karrington
were $2.4 million after paying off a related note payable of approximately $1.1
million. The net proceeds were used to provide additional funds to support
Karrington's working capital needs.
 
     Under the amended merger agreement described in Note 12 to Consolidated
Financial Statements, Sunrise has made available to Karrington a $16.5 million
line of credit to be used for construction and development activities and
working capital. The line of credit expires in January 2000.
 
     In March 1999, the Company obtained a commitment from JMAC, Inc. which
provides up to $4 million for working capital needs. Such commitment terminates
upon the earlier of the closing of the Sunrise transaction discussed in Note 12
to Consolidated Financial Statements or January 1, 2000.
 
     See Note 13 to Consolidated Financial Statements for a discussion of risks
and uncertainties. Karrington believes its existing financing commitments,
including the Sunrise line of credit, together with additional anticipated
financing, will be sufficient to fund its development, construction and working
capital needs through 1999.
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARD
 
     In April 1998, the Accounting Standards Executive Committee issued SOP
98-5, "Reporting on the Costs of Start-Up Activities." SOP 98-5 requires that
the costs of start-up activities and organization costs be expensed as incurred.
SOP 98-5 is effective for fiscal years beginning after December 15, 1998 with
earlier application encouraged. Management will apply the provisions of the SOP
in the first quarter of 1999. The application of SOP 98-5 will require
Karrington to write-off all existing deferred preopening and organization costs
and expense all such items as incurred on a prospective basis. Preopening and
organization costs were $1.9 million at January 1, 1999.
 
IMPACT OF YEAR 2000
 
     Karrington has completed its review of the impact of the Year 2000 issue on
its information and financial systems and is in the process of spending about
$700,000 to upgrade hardware and software to be Year 2000 compliant. Karrington
is implementing a Year 2000 compliant home administrative information system
which will provide better and faster information, particularly regarding
resident history, service needs, and associated billing. This upgrade and
implementation began in the fourth quarter of 1998
 
                                       91
<PAGE>   101
 
and is expected to be completed during the third quarter of 1999. The upgrade
will be financed from working capital and anticipated financing.
 
     Karrington is in the process of its review of all mechanical equipment,
including telephone systems, elevators, security systems, HVAC systems and
vehicles. This review will be completed by the end of the second quarter of
1999. Karrington believes its review is approximately 80% complete. To date,
Karrington has not identified any problems or issues which would require a
significant investment of time or capital.
 
     The efforts described above should provide Karrington with an internal
solution to the Year 2000 issue. However, Karrington remains cautious and
continues to review external issues that may impact the business or flow of
funds. Karrington's payroll is processed by an independent third party that has
assured Karrington it will be Year 2000 compliant. Karrington will make
contingent plans to resort to manual operations if particular external
interfaces fail. Karrington is continuing its review of Year 2000 issues.
 
   
                        INTEREST RATE RISK OF KARRINGTON
    
 
   
     As part of its ongoing business, Karrington is exposed to changes in
interest rates primarily from its long-term debt instruments. As of December 31,
1998, Karrington has various fixed and variable rate debt instruments
outstanding that have been used primarily to finance its development and
construction activities. Under its current policies, Karrington does not use
interest rate derivative instruments to manage exposure to interest rate
changes.
    
 
   
     For fixed rate debt, changes in interest rates generally affect the fair
market value, but not earnings or cash flows. Conversely, for variable rate
debt, changes in interest rates generally do not impact fair market value, but
do affect the future earnings and cash flows. Karrington generally cannot prepay
fixed rate debt prior to maturity, therefore, interest rate risk and changes in
fair market value should not have a significant impact on the fixed rate debt
until Karrington would be required to refinance such debt. Holding the December
31, 1998 variable rate debt balance constant, each percentage point increase in
interest rates would result in an increase in interest expense for 1999 of
approximately $572,000.
    
 
   
     The following table summarizes information about Karrington's debt
instruments that are sensitive to changes in interest rates as of December 31,
1998. For debt instruments, the table presents principal cash flows and related
weighted-average interest rates by expected maturity dates. Weighted-average
variable interest rates are based on Karrington's floating rate indices as of
December 31, 1998. Karrington's floating rate indices on its debt arrangements
range from prime to prime plus 1.25%, LIBOR plus 1.25% to LIBOR plus 2.75% and a
weekly floater rate on Karrington's outstanding revenue bond.

                      DESCRIPTION OF SUNRISE CAPITAL STOCK
 
   
     The following description of the capital stock of Sunrise, including the
Sunrise common stock to be issued in the merger, is not complete and is
qualified in its entirety by reference to the certificate of incorporation of
Sunrise. For information on how you can obtain a copy of the certificate of
incorporation of Sunrise, see "Where You Can Find More Information" on page 112.
    
 
GENERAL
 
     The authorized capital stock of Sunrise consists of 60,000,000 shares of
Sunrise common stock, par value $.01 per share, and 10,000,000 shares of
preferred stock, par value $.01 per share, of which 30,000 shares of the Sunrise
preferred stock have been designated as "series C junior participating preferred
stock." At March 15, 1999, 19,510,726 shares of Sunrise common stock and no
shares of Sunrise preferred stock were outstanding.
 
SUNRISE COMMON STOCK
 
     Each holder of Sunrise common stock is entitled to one vote for each share
on all matters submitted to a vote of stockholders. The certificate of
incorporation of Sunrise does not provide for cumulative voting. Accordingly,
the holders of a majority of the shares of Sunrise common stock entitled to vote
in any election of directors may elect all of the directors standing for
election.
 
     The certificate of incorporation of Sunrise provides that, subject to the
rights of the holders of Sunrise preferred stock, the holders of Sunrise common
stock are entitled to receive any dividends declared by the Sunrise board of
directors out of legally available funds. In the event of any liquidation,
dissolution or winding up of Sunrise, the holders of Sunrise common stock are
entitled to participate in the distribution of all assets of Sunrise remaining
after the payment of all debts of Sunrise and the payment of the full amounts,
if any, to which the holders of Sunrise preferred stock are entitled have been
paid or set aside for payment.
 
     The holders of Sunrise common stock have no preemptive, subscription,
redemption or conversion rights. The rights, preferences and privileges of
holders of Sunrise common stock are subject to the rights of the holders of any
shares of any series of preferred stock that Sunrise may issue in the future.
 
SUNRISE PREFERRED STOCK
 
     The board of directors of Sunrise is authorized to issue preferred stock in
series and to fix and state the voting powers, full or limited, or no voting
powers, and the designations, preferences and relative participating, optional
or other special rights of the shares of each series and the qualifications,
limitations and restrictions of the shares of each series. The Sunrise board may
issue shares of preferred stock without stockholder approval. Under the
certificate of incorporation of Sunrise, each share of each series of Sunrise
preferred stock is to be identical in all respects with all other shares of the
same series.
                                       96
<PAGE>   106
 
     While providing flexibility in connection with possible financings,
acquisitions and other corporate purposes, the issuance of preferred stock by
Sunrise could adversely affect the voting power of the holders of Sunrise common
stock. In addition, Sunrise could issue preferred stock as a means of
discouraging, delaying or preventing a change in control of Sunrise. Sunrise has
no present plans to issue shares of its preferred stock.
 
TRANSFER AGENT AND REGISTRAR
 
     First Union National Bank is the transfer agent and registrar for the
Sunrise common stock.
 
SUNRISE STOCKHOLDER RIGHTS PLAN
 
     On April 25, 1996, the board of directors of directors of Sunrise adopted a
stockholder rights plan. At that time, the board of directors of Sunrise
declared a dividend of one preferred share purchase right for each outstanding
share of Sunrise common stock. All shares of Sunrise common stock issued between
April 25, 1996 and the distribution date of the rights, or the date, if any, on
which the rights are redeemed, will have rights attached to them. The rights
expire on the tenth anniversary of the date the rights agreement was adopted,
unless earlier redeemed or exchanged. Each right, when exercisable, entitles the
holder to purchase one one-thousandth of a share of series C junior
participating preferred stock of Sunrise at a price of $85.00. Until a right is
exercised, the holder of the right will have no rights as a stockholder of
Sunrise, including, the right to vote or to receive dividends.
 
     The rights initially attach to all certificates representing shares of
outstanding Sunrise common stock. The rights will separate from the Sunrise
common stock and rights certificates will be distributed upon the earlier to
occur of (a) 10 days following a public announcement that a person or group of
affiliated or associated persons has acquired, or obtained the right to acquire,
beneficial ownership of 20% or more of the outstanding shares of Sunrise common
stock or (b) 10 business days, or such later date as the board of directors of
Sunrise may determine, following the commencement of a tender offer or exchange
offer, the consummation of which would result in the beneficial ownership by a
person of 20% or more of the outstanding shares of Sunrise common stock. Neither
Paul J. Klaassen nor Teresa M. Klaassen, each of whom, as of April 25, 1996,
beneficially owned more than 20% of the outstanding Sunrise common stock, nor
any of their affiliates will be deemed an "acquiring person" for purposes of the
rights plan, unless they acquire an additional 2% of the outstanding shares of
Sunrise common stock in excess of the amount beneficially owned by them as of
April 25, 1996.
 
     Generally, if a person or entity becomes the beneficial owner of 20% or
more of the then outstanding shares of Sunrise common stock, each holder of a
right may, after the end of a redemption period, exercise the right by
purchasing Sunrise common stock having a value equal to two times the purchase
price of the right.
 
     If at any time following the date a person or entity becomes the beneficial
owner of 20% or more of the then outstanding shares of Sunrise common stock, (a)
Sunrise is acquired in a merger or other business combination transaction in
which it is not the
 
                                       97
<PAGE>   107
 
surviving corporation, or (b) 50% or more of Sunrise's assets or earning power
is sold or transferred, each holder of a right shall have the right to receive,
upon exercise, common stock of the acquiring company having a value equal to two
times the purchase price of the right.
 
     In general, the board of directors of Sunrise may redeem the rights at a
price of $.005 per right at any time until ten days after the acquiror has been
identified. If the decision to redeem the rights is made after the acquiror
becomes the beneficial owner of 20% or more of the then outstanding shares of
Sunrise common stock, two-thirds of the directors must approve the decision to
redeem the rights.
 
     The rights have anti-takeover effects. The rights will cause substantial
dilution to a person or group that attempts to acquire Sunrise. The rights,
however, will not interfere with any merger or other business combination
approved by the board of directors of Sunrise since the board of directors of
Sunrise may, at its option, at any time prior to any person becoming an
Acquiring Person, redeem all rights or amend the stockholder rights agreement to
exempt the person from the stockholder rights agreement.
 
                        COMPARISON OF SHAREHOLDER RIGHTS
 
     The following a summary of the material differences between the rights of
Karrington shareholders, on the one hand, and Sunrise stockholders, on the other
hand. These differences arise from the differences between the Delaware and Ohio
law and the governing instruments of Sunrise and Karrington.
 
CLASSIFICATION OF THE BOARD OF DIRECTORS
 
     The Delaware General Corporation Law permits a Delaware corporation's board
of directors to be divided into up to three classes with staggered terms of
office. The certificate of incorporation of Sunrise divides the board of
directors into three classes. Each class consists of approximately one-third of
the total number of directors. The term of office of each class is three years
and expires in successive years at the time of the annual meeting of
stockholders.
 
     The Ohio General Corporation Law permits an Ohio corporation's board of
directors to be divided into up to three classes of at least three directors
each with staggered terms of office. Karrington's code of regulations classifies
the board of directors of Karrington into three classes. Each class is elected
in staggered elections and serves a three-year term.
 
     Classification of directors has the effect of making it more difficult for
stockholders to change the composition of a board of directors. At least two
annual meetings of stockholders, instead of one, generally will be required to
effect a change in a majority of the board of directors. This delay may help
ensure that the board of directors, if confronted by a holder attempting to
force a proxy contest, a tender or exchange offer or other extraordinary
corporate transaction, would have sufficient time to review the proposal as well
as any available alternatives to the proposal and to act in what it believes to
be the best interests of the stockholders.
 
                                       98
<PAGE>   108
 
     Classification provisions also could have the effect of discouraging a
third party from initiating a proxy contest, making a tender offer or otherwise
attempting to obtain control of Sunrise or Karrington, even though such a
transaction could be beneficial to Sunrise or Karrington, as the case may be, or
their respective stockholders.
 
NUMBER OF DIRECTORS; REMOVAL OF DIRECTORS; VACANCIES
 
     The Delaware General Corporation Law permits the certificate of
incorporation or bylaws to contain provision regarding the number of directors.
The certificate of incorporation of Sunrise specifies that Sunrise shall have a
minimum of two and a maximum of eleven directors. The exact number of directors
within this range is fixed by a two-thirds vote of the directors.
 
     The Karrington code of regulations provides that the number of directors
may be fixed or changed either by the board of directors or the shareholders of
Karrington acting by a majority vote.
 
     Under the Delaware General Corporation Law, unless otherwise provided in a
corporation's certificate of incorporation, directors serving on a classified
board of directors may be removed by the stockholders only for cause. The
Sunrise amended and restated certificate of incorporation provides that
stockholders may remove a director with cause by the affirmative vote of the
holders of at least a majority of the outstanding shares of capital stock then
entitled to vote at an election of directors.
 
     The Karrington code of regulations provide that the shareholders may remove
a director or the entire board of directors from office only for cause and by an
affirmative vote of at least a majority of the voting power of the holders of
Karrington common stock entitled to elect directors. At the same meeting a new
director may be elected for the unexpired term.
 
     The Delaware General Corporation Law provides that, unless the governing
documents of a corporation provide otherwise, vacancies and newly created
directorships may be filled by a majority of the remaining directors. Any
vacancy occurring in the board of directors of Sunrise may be filled for the
unexpired term by the vote of a majority of the directors. Any director so
chosen will hold office for the remainder of the full term of the class in which
the new directorship was created or the vacancy occurred.
 
     The Karrington code of regulations and the Ohio General Corporation Law
also provide that a vacancy in the board may be filled by a majority of the
remaining directors. Any director so elected will serve for the remainder of the
unexpired term.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION OF DIRECTORS
 
     The Delaware General Corporation Law provides that a corporation's
certificate of incorporation may include a provision limiting the personal
liability of a director to the
 
                                       99
<PAGE>   109
 
corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director. However, no such provision can eliminate or limit the
liability of a director for:
 
     - any breach of the director's duty of loyalty to the corporation or its
       stockholders;
 
     - acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;
 
     - for unlawful payments of dividends and unlawful stock purchases or
       redemptions under Section 174 of the Delaware General Corporation Law; or
 
     - for any transaction from which the director derived an improper personal
       benefit.
 
As permitted by Delaware law, the certificate of incorporation of Sunrise
contains such a provision limiting the personal liability of a director of
Sunrise to the corporation or its stockholders for monetary damages for breach
fiduciary duty as a director.
 
     The Ohio General Corporation Law provides, with limited exceptions, that a
director may be held liable in damages for acts or omissions as a director only
if it is proved by clear and convincing evidence that the director undertook the
act or omission with deliberate intent to cause injury to the corporation or
with reckless disregard for its best interests.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Delaware law generally permits a corporation to indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding by reason of the fact that the person is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request of the corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise. Each such person is indemnified against expenses, judgments, fines
and amounts paid in settlement actually and reasonably incurred in connection
with a third party action, other that a derivative action, and against expenses
actually and reasonably incurred in the defense or settlement of a derivative
action, provided that there is a determination that the individual acted in good
faith and in a manner reasonably believed to be in or not opposed to the best
interests of the corporation. This determination is required to be made, in the
case of an individual who is a director or officer at the time of such
determination:
 
     - by a majority of the disinterested directors, even though less than a
       quorum;
 
     - by a committee of such directors designated by a majority vote of such
       directors, even though less than a quorum;
 
     - by independent legal counsel, regardless of whether a quorum of
       disinterested directors exists; or
 
     - by a majority vote of the stockholders, at a meeting at which a quorum is
       present.
 
     Without court approval, however, no indemnification may be made in respect
of any derivative action in which the individual is adjudged liable to the
corporation.
 
                                       100
<PAGE>   110
 
     Delaware law requires indemnification of present and former directors and
officers for expenses relating to a successful defense on the merits or
otherwise of a derivative or third-party action.
 
     Delaware law permits a corporation to advance expenses relating to the
defense of any proceeding to present directors and officers contingent upon the
individuals' commitment to repay any advances unless it is determined ultimately
that the individuals are entitled to be indemnified. Expenses incurred by former
directors and officers or other employee and agents may be paid on the terms and
conditions the corporation deems appropriate.
 
     Under Delaware law, the rights to indemnification and advancement of
expenses provided in the law are non-exclusive. Subject to public policy issues,
indemnification and advancement of expenses beyond that provided by statute may
be provided by bylaw, agreement, vote of stockholders, disinterested directors
or otherwise.
 
     To the maximum extent permitted by law, the bylaws of Sunrise provide for
mandatory indemnification of present and former directors and officers of
Sunrise. Present and former directors and officers of Sunrise are indemnified
against any expense, liability and loss to which they may become subject, or
which they may incur, as a result of being or having been a director or officer
of Sunrise. In addition, Sunrise must advance or reimburse present and former
directors and officers for expenses incurred by them in connection with
indemnifiable claims.
 
     Sunrise has entered into separate indemnification agreements with its
directors and officers. Each indemnification agreement provides for Sunrise to
indemnify such persons, to the fullest extent permitted by Delaware law, against
any expense, liability and loss to which they may become subject, or which they
may incur, as a result of being or having been a director or officer of Sunrise.
In addition, Sunrise must advance or reimburse directors and officers for
expenses incurred by them in connection with indemnifiable claims. Sunrise also
maintains directors' and officers' liability insurance.
 
     Under the Ohio General Corporation Law, Ohio corporations may indemnify
directors from liability if the director acted in good faith and in a manner
reasonably believed by the director to be in, or not opposed to, the best
interests of the corporation. With respect to any criminal actions, Ohio
corporations may indemnify directors from liability if the director also had no
reason to believe the action was unlawful. In the case of an action by or on
behalf of a corporation, indemnification may not be made:
 
     - if the person seeking indemnification is adjudged liable for negligence
       or misconduct, unless the court in which such action was brought
       determines such person is fairly and reasonably entitled to
       indemnification; or
 
     - if liability asserted against such person concerns unlawful
       distributions. The indemnification provisions of the Ohio General
       Corporation Law require indemnification of a director who has been
       successful on the merits or otherwise in defense of any action, suit or
       proceeding that he or she was a party to by reason of the fact that he or
       she is or was a director of the corporation. The indemnification
       authorized by the Ohio General Corporation Law is not exclusive
 
                                       101
<PAGE>   111
 
       and is in addition to any other rights granted to directors under the
       articles of incorporation or regulations of the corporation or to any
       agreement between the directors and the corporation.
 
     The Karrington code of regulations provides for mandatory indemnification
of each present or former director or officer who was or is a party or is
threatened to be made a party to any threatened, pending or complete action,
suit or proceeding, because he or she is or was a director, officer, manager or
agent of the corporation, or is or was serving at Karrington's request as a
director, trustee, officer, employee, member, manager or agent of another
corporation, limited liability company, partnership, joint venture, trust or
other enterprise. Each such person is indemnified against expenses, judgments,
fines and amounts paid in settlement, in connection with such action, suit or
proceeding if he or she acted in good faith and in a manner he or she reasonably
believed to be in, or not opposed to, the best interests of the corporation.
With respect to any criminal action or proceeding, the person to be indemnified
also must have had no reasonable cause to believe his or her conduct was
unlawful. A person claiming indemnification is presumed to have acted in good
faith and in a manner he or she reasonably believed to be in, and not opposed
to, the best interests of the corporation. With respect to any criminal matter,
the person claiming indemnification also is presumed to have had no reasonable
cause to believe his or her conduct was unlawful.
 
CALL OF SPECIAL MEETINGS OF STOCKHOLDERS
 
     The Delaware General Corporation Law provides that special meetings of
stockholders may be called by the board of directors or by such other persons as
are authorized by the corporation's certificate of incorporation or bylaws. The
Sunrise certificate of incorporation and bylaws provide that a special meeting
of the stockholders of Sunrise may be called by board of directors of Sunrise,
the chairman of the board of directors or the president of Sunrise and will be
called by the secretary upon the written request of stockholders possessing at
least 25% of the voting power of the issued and outstanding Sunrise voting stock
entitled to vote generally for the election of directors.
 
     The Ohio General Corporation Law provides that a special meeting of
shareholders may be called by the chairman of the board of directors, the
president, the directors at a meeting, or a majority of the directors without a
meeting, persons holding 25% or more of the shares entitled to vote at this
meeting, unless the articles of incorporation or regulations specify a greater
or lesser percentage but not more than a majority, or the other officers or
persons specified in the articles of incorporation or the code of regulations.
The Karrington code of regulations increase to 50% the number of shares required
to call a meeting and provide that, in the case of the president's absence,
death or disability, the vice president authorized to exercise the authority of
the president may call a meeting.
 
SHAREHOLDER ACTION BY WRITTEN CONSENT
 
     The Delaware General Corporation Law provides that, unless otherwise
provided in the certificate of incorporation, any action required to be taken at
any annual or special
 
                                       102
<PAGE>   112
 
meeting of such 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 action so taken, will 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. The Sunrise certificate of
incorporation provides that any action required or permitted to be taken by the
stockholders of Sunrise must be effected at a duly called annual or special
meeting of such holders and may not be effected by any consent in writing by
such holders, unless such consent is unanimous.
 
     Under the Ohio General Corporation Law, unless a corporation's articles of
incorporation or regulations prohibit the taking of action without a meeting,
any action required or permitted to be taken at a meeting of the shareholders
may be taken without a meeting with the affirmative vote in a writing setting
forth the action signed by all shareholders who would be entitled to notice of a
meeting. The Karrington code of regulations authorize the shareholders to take
action by unanimous consent in writing without a meeting. However, the
Karrington code of regulations may be amended only at a meeting of shareholders
held for such purpose.
 
CUMULATIVE VOTING
 
     The Delaware General Corporation Law permits the certificate of
incorporation to provide that, in all elections of directors, each stockholder
is entitled to cumulate such stockholder's votes. The Sunrise certificate of
incorporation does not provide for cumulative voting.
 
     Under the Ohio General Corporation Law, unless otherwise provided in a
corporation's articles of incorporation, each shareholder is entitled to
cumulate such shareholder's votes in the election of directors if the
shareholder gives notice to the corporation. The Karrington articles of
incorporation prohibit cumulative voting.
 
ADVANCE NOTICE PROVISIONS FOR SHAREHOLDER PROPOSALS AND SHAREHOLDER NOMINATIONS
 
     Under the Sunrise bylaws, for stockholders to properly introduce business
to be transacted at the annual meeting of stockholders, a stockholder must give
timely notice of such proposal in a proper written form delivered to Sunrise's
principal executive offices. To be timely, a stockholder's notice to Sunrise
must be delivered to or mailed and received at Sunrise's principal executive
offices not less than 60 days prior to the meeting. However, if less than 75
days' notice of the date of the meeting is given or made to stockholders, notice
by the stockholder to be timely must be received not later than the close of
business on the 15th day following the notice of the date of the annual meeting.
 
     The Sunrise bylaws require that a stockholder's notice include:
 
     - a brief description of the business desired to be brought before the
       annual meeting and the reasons for conducting such business at the annual
       meeting;
 
     - the name and address of such stockholder, as they appear on Sunrise's
       books;
 
                                       103
<PAGE>   113
 
     - the class and number of shares of Sunrise common stock which are
       beneficially owned; and
 
     - any material interest of such stockholder in such business.
 
     The Sunrise bylaws permit stockholders to nominate persons for election to
the board of directors of Sunrise at a meeting of stockholders if the
stockholder gives timely notice of such nomination in a proper written form to
Sunrise. To be timely, the stockholder's notice must meet the same timeliness
requirements as described above for providing advance notice of business to be
transacted at the annual meeting of stockholders.
 
     The Sunrise bylaws require that a stockholder's notice include, as to each
person that the stockholder proposes to nominate for election or re-election as
a director:
 
     - the name, age, business address and residence address of such person;
 
     - the principal occupation or employment of such person;
 
     - the class and number of shares of Sunrise common stock which are
       beneficially owned by such person; and
 
     - any other information relating to such person that is required to be
       disclosed in solicitations of proxies for the election of directors, or
       is otherwise required, in each case under Regulation 14A under the
       Securities Exchange Act. In addition, the stockholder's notice must
       include, as to the stockholder giving the notice (A) the name and address
       of such stockholder, as they appear on Sunrise's books; and (B) the class
       and number of shares of Sunrise common stock which are beneficially
       owned.
 
     The Karrington code of regulations permit shareholders to bring business
before an annual meeting of shareholders if done in compliance with Rule 14a-8
under the Securities Exchange Act. The Karrington code of regulations also
permit any shareholder entitled to vote in the election of directors to nominate
one or more persons for election as directors only if written notice of such
shareholder's intent to make the nomination or nominations has been given to the
secretary of the corporation. This notice must be delivered to the principal
executive offices of the corporation not later than the date on which a
shareholder proposal would be required to be delivered as described above. The
notice shall set forth:
 
     - the name and address of the nominating shareholder and of the proposed
       nominee;
 
     - a representation that the shareholder is a shareholder of record of
       shares of the corporation entitled to vote at such meeting and intends to
       appear in person or by proxy at the meeting to nominate the person or
       persons specified in the notice;
 
     - a description of all arrangements or understandings between the
       shareholder and each nominee and any other person, who must be named in
       the notice, under which the nomination or nominations are made by the
       shareholder;
 
                                       104
<PAGE>   114
 
     - such other information relating to each nominee proposed by such
       shareholder as would be required to be included in a proxy statement
       filed under the proxy rules of the SEC had the nominee been nominated, or
       intended to be nominated, by the board of directors of the corporation;
       and
 
     - the consent of each nominee to serve as a director of the corporation if
       so elected.
 
AMENDMENTS TO CHARTER DOCUMENTS AND BYLAWS
 
     The Delaware General Corporation Law provides that the certificate of
incorporation of a corporation may be amended upon adoption by the board of
directors of a resolution setting forth the proposed amendment and declaring its
advisability, followed by the favorable vote of the holders of a majority of the
outstanding stock entitled to vote on the amendment. It also provides that a
certificate of incorporation may require a greater vote than would otherwise be
required by the Delaware General Corporation Law.
 
     Except as set forth in the Sunrise certificate of incorporation or as
otherwise specifically required by law, no amendment of any provision of the
Sunrise certificate of incorporation may be made unless such amendment has been
first proposed by at least two-thirds of the directors of Sunrise then in office
and approved by the holders of at least a majority of the outstanding shares of
stock of Sunrise entitled to vote on such matter. However, the amendment must be
approved by the holders of at least two-thirds of the outstanding shares of
stock entitled to vote on the amendment if the amendment is to any of the
following provisions in the Sunrise certificate of incorporation, some of which
are described above:
 
     - the classified board;
 
     - the number and removal of directors;
 
     - vacancies in the board of directors;
 
     - stockholder action by written consent;
 
     - the calling of special meetings;
 
     - the authorized number of shares of preferred stock;
 
     - board authority to issue Sunrise preferred stock;
 
     - the limitation on directors liability;
 
     - amendments of the bylaws; or
 
     - the provision requiring that the board consider the effect of acquisition
       proposals on constituencies other than the stockholders.
 
     Under the Delaware General Corporation Law, the power to adopt, alter and
repeal the bylaws is vested in the stockholders unless the certificate of
incorporation vests this power in the directors. Vesting this power in the
directors does not divest the stockholders of power to adopt, alter or repeal
the bylaws. The Sunrise certificate of incorporation and the bylaws provide that
the board of directors of Sunrise or its
 
                                       105
<PAGE>   115
 
stockholders may alter, amend or repeal the Sunrise bylaws if the amendment is
approved by the affirmative vote of at least two-thirds of the directors then in
office or of at least two-thirds of the outstanding shares of stock entitled to
vote on the matter.
 
     Under the Ohio General Corporation Law, an amendment to the articles of
incorporation requires the affirmative vote of two-thirds of the voting power of
a corporation unless a greater or lesser percentage, which cannot be less than a
majority, is specified in the corporation's articles of incorporation. The
Karrington articles of incorporation do not provide any differences from the
Ohio General Corporation Law.
 
     Under the Ohio General Corporation Law, the power to adopt, alter and
repeal the code of regulations of a corporation is vested in the shareholders.
Shareholders of an Ohio corporation may amend the regulations by the affirmative
vote of a majority of the voting power of the corporation or without a meeting
by the written consent of the holders of two-thirds of the voting power of the
corporation unless the articles of incorporation or regulations provide for a
greater percentage. The Karrington code of regulations may be amended or
repealed by the affirmative vote of a majority of the voting power. However, the
affirmative vote of 66 2/3% of the voting power is required to amend the
provisions of the Karrington code of regulations relating to the calling of
shareholders' meetings, the number of directors and term of office, the election
and removal of directors, indemnification and insurance of officers and
directors, amendment of the Karrington code of regulations, or action by
shareholders or directors without a meeting.
 
MERGERS, CONSOLIDATIONS AND SALES OF ASSETS
 
     The Delaware General Corporation Law requires approval of mergers,
consolidations and sales of all or substantially all of a corporation's assets,
other than so-called parent-subsidiary mergers, by a majority of the voting
power of the corporation, unless the certificate of incorporation specifies a
different percentage. The Sunrise certificate of incorporation does not provide
for a different percentage. Section 203 of the Delaware General Corporation Law
prohibits "business combinations" with "interested stockholders" unless the
provisions of that section of Delaware law are satisfied. See the discussion
below under "-- Business Combinations; Transactions with Interested
Stockholders."
 
     The Ohio General Corporation Law generally requires approval of mergers,
dissolutions, dispositions of all or substantially all of a corporation's
assets, and majority share acquisitions and combinations involving issuances of
shares representing one-sixth or more of the voting power of the corporation,
other than so-called parent-subsidiary mergers, by two-thirds of the voting
power of the corporation unless the articles of incorporation specify a
different proportion, which may not be less than a majority. The Karrington
articles of incorporation do not provide for a different proportion.
 
BUSINESS COMBINATIONS; TRANSACTIONS WITH INTERESTED SHAREHOLDERS
 
     Section 203 of the Delaware General Corporation Law provides, in general,
that an "interested stockholder," defined generally as a stockholder acquiring
more than 15% of
 
                                       106
<PAGE>   116
 
the outstanding voting shares of a corporation subject to the statute, but less
than 85% of such shares, may not engage in "business combinations" with the
corporation for a period of three years after the date on which the stockholder
became an interested stockholder, unless:
 
     - prior to such date the corporation's board of directors approved either
       (a) the business combination or (b) the transaction in which the
       stockholder became in interested stockholder; or
 
     - the "business combination" is approved by the corporation's board of
       directors and authorized by a vote of at least two-thirds of the
       outstanding voting stock of the corporation not owned by the interested
       stockholder.
 
     Section 203 defines a "business combination" to encompass a wide variety of
transactions with or caused by an interested stockholder in which the interested
stockholder receives or could receive a benefit on other than a pro rata basis
with other stockholders, including mergers, specified asset sales, specified
issuances of additional shares to the interested stockholder, transactions with
the corporation which increase the proportionate interest of the interested
stockholder or a transaction in which the interested stockholder receives other
benefits.
 
     When Sunrise was formed in 1994, the Klaassens, their respective affiliates
and their respective estates were exempted from the provisions of Section 203 of
the Delaware General Corporation Law.
 
     Chapter 1704 of the Ohio General Corporation Law prohibits, subject to
exceptions, business combinations and transactions between an issuing public
corporation and an "interested shareholder," generally defined as a beneficial
owner of 10% or more of the shares of the corporation, for at least three years
after the interested shareholder attains 10% ownership, unless the board of
directors of the issuing public corporation approves the transaction before the
interested shareholder attained 10% ownership. An "issuing public corporation"
is defined in the Ohio General Corporation Law as an Ohio corporation with 50 or
more shareholders that has its principal place of business, principal executive
offices, or substantial assets within the state of Ohio, and as to which no
close corporation agreement exists. Karrington is an "issuing public
corporation."
 
     Examples of transactions regulated by Chapter 1704 of the Ohio General
Corporation Law include the disposition of assets, mergers, consolidations,
voluntary dissolutions and the transfer of shares. After the three-year period,
a transaction regulated by Chapter 1704 may take place provided that specified
conditions are satisfied, including that:
 
     - the board of directors approves the transaction;
 
     - the transaction is approved by the holders of shares with at least
       two-thirds of the voting power of the corporation, or a different
       proportion set forth in the articles of incorporation, including at least
       a majority of the outstanding shares after excluding shares controlled by
       the interested shareholder; or
 
                                       107
<PAGE>   117
 
     - the business combination results in shareholders, other than the
       interested shareholder, receiving a fair price, as determined by Section
       1704.03(A)(4), for their shares. Neither the Karrington articles of
       incorporation nor the Karrington code of regulations contain this type of
       election to be excluded from Chapter 1704.
 
     Although Chapter 1704 of the Ohio General Corporation Law is similar to
Section 203 of the Delaware General Corporation Law in some respects, there are
significant differences. Chapter 1704 provisions are triggered by the
acquisition of 10% of the voting power of a subject Ohio corporation rather than
15%. If before the acquisition of shares by which a person becomes an interested
shareholder, the board of directors of the corporation approves the transaction
by which the person would become an interested shareholder, then Chapter 1704's
prohibition does not apply. The prohibition imposed by Chapter 1704 continues
indefinitely after the initial three-year period unless the subject transaction
is approved by the requisite vote of the shareholders or satisfies statutory
conditions relating to the fairness of consideration received by shareholders,
other than the interested shareholder. Chapter 1704 does not provide any
exemption for an interested shareholder who acquires a significant percentage of
stock in the transaction which resulted in the shareholder becoming an
"interested shareholder" as does Section 203. Chapter 1704's definition of
"beneficial owner" of shares is essentially similar to that of Section 203
except that Chapter 1704 does not expressly exclude from the definition of
beneficial owner a person who has the right to vote stock under an agreement
which arises solely from a revocable proxy.
 
     Section 1701.831 of the Ohio General Corporation Law, known as the "Control
Share Acquisition Act," provides that specified notice and informational filings
and special shareholder meetings and voting procedures must occur before
consummation of a proposed "control share acquisition." "Control share
acquisition" is defined as any acquisition of an issuer's shares that would
entitle the acquirer to exercise or direct the voting power of the issuer in the
election of directors within any of the following ranges:
 
     - one-fifth or more but less than one-third of such voting power;
 
     - one-third or more but less than a majority of such voting power; or
 
     - a majority or more of such voting power.
 
Assuming compliance with the notice and information filing requirements
prescribed by the statute, the proposed control share acquisition may take place
only if the acquisition is approved by both a majority of the voting power of
the issuer represented at the meeting and a majority of the voting power
remaining after excluding the combined voting power of the intended acquirer,
directors of the issuer who are also employees and officers of the issuer, and
persons that acquire specified amounts of shares after the public disclosure of
the proposed control share acquisition. The Control Share Acquisition Act does
not apply to a corporation whose articles of incorporation or code of
regulations so provide. Karrington has not opted out of the application of the
Control Share Acquisition Act.
 
                                       108
<PAGE>   118
 
     The Delaware General Corporation Law contains no provisions comparable to
Section 1701.831 of the Ohio General Corporation Law.
 
APPRAISAL RIGHTS
 
     Under the Delaware General Corporation Law, appraisal rights are available
only in connection with statutory mergers or consolidations. Even in these
cases, unless the certificate of incorporation otherwise provides, the Delaware
General Corporation Law does not recognize dissenters' rights for any class or
series of stock which is either listed on a national securities exchange or held
of record by more than 2,000 stockholders. However, appraisal rights are
available for holders of stock who, by the terms of the merger or consolidation,
are required to accept anything except: (A) stock of the corporation surviving
or resulting from the merger or consolidation; (B) shares which at the effective
time of the merger or consolidation are either listed on a national securities
exchange or held of record by more than 2,000 stockholders; (C) cash instead of
fractional shares of stock described in clauses (A) and (B); or (D) any
combination of stock and cash instead of fractional shares described in clauses
(A), (B) or (C).
 
     Under the Ohio General Corporation Law, dissenting shareholders are
entitled to dissenters' rights in connection with the transfer of all or
substantially all of the assets of a corporation and in connection with
specified amendments to a corporation's articles of incorporation. Shareholders
of an Ohio corporation being merged into or consolidated with another
corporation are also entitled to dissenters' rights. In addition, shareholders
of an acquiring corporation are entitled to dissenters' rights in any merger,
combination or majority share acquisition in which the shareholders of the
acquiring corporation are entitled to vote. The Ohio General Corporation Law
provides shareholders of an acquiring corporation voting rights if the
acquisition involves the transfer of shares of the acquiring corporation
entitling the recipients of such shares to exercise one-sixth or more of the
voting power of the acquiring corporation.
 
STOCKHOLDER RIGHTS PLAN
 
     Sunrise has adopted a stockholder rights plan.   See "Description of
Sunrise Capital Stock -- Sunrise Stockholder Rights Plan."
 
     Karrington does not have a shareholder rights plan.
 
DIVIDENDS
 
     Both the Delaware General Corporation Law and the Ohio General Corporation
Law provide that dividends may be paid in cash, property or shares of a
corporation's capital stock. The Delaware General Corporation Law provides that
a corporation may pay dividends out of any surplus, and, if it has no surplus,
out of any net profits for the fiscal year in which the dividend was declared or
for the preceding fiscal year. However, any such payment cannot reduce capital
below the amount of capital represented by all classes of shares having a
preference upon the distribution of assets. The Ohio General Corporation Law
provides that a corporation may pay dividends out of surplus and must notify its
shareholders if a dividend is paid out of capital surplus.

CONSIDERATION OF OTHER CONSTITUENCIES
 
     The Sunrise certificate of incorporation requires the board of directors of
Sunrise to give due consideration to all relevant factors in connection with the
exercise of its judgment in determining what is in the best interests of the
corporation and its stockholders. Relevant factors may include the social,
economic and regulatory effects on Sunrise, on its employees, providers and
payors, on residents and families served by Sunrise, on operations of Sunrise's
subsidiaries and on communities in which Sunrise and its subsidiaries operate
when evaluating any offer, bid, proposal, or similar communication of another
party to:
 
     - make a tender or exchange offer;
 
     - merge or consolidate Sunrise with or into another corporation; or
 
     - purchase all or substantially all of the assets of Sunrise.
 
     Section 1701.59 of the Ohio General Corporation Law permits a director, in
determining what such director reasonably believes to be in the best interests
of the corporation, to consider, in addition to the interests of the
corporation's shareholders, any of the following:
 
     - the interests of the corporation's employees, suppliers, creditors, and
       customers;
 
     - the economy of the state and nation;
 
     - community and societal considerations; and
 
     - the long-term as well as short-term interests of the corporation and its
       shareholders, including the possibility that these interests may be best
       served by the continued independence of the corporation.
 
REGISTRATION RIGHTS
 
     Under a registration agreement dated January 4, 1995, the Klaassens are
entitled to registration rights with respect to 2,800,780 shares of Sunrise
common stock owned by them. The following summary is not complete and is subject
to, and qualified in its entirety by, the Klaassen registration agreement.
 
     Demand Registration.  The Klaassens may request that Sunrise offer some or
all of the shares subject to their registration agreement to the public under an
effective registration statement under the Securities Act. Registration on Form
S-1 or Form S-3 may be demanded by either of the Klaassens, provided that not
less than 25% of the shares subject to the registration agreement are requested
to be registered, and, in the case of a Form S-3 registration statement, that
the aggregate offering value of the shares requested to be included in such
registration must be reasonably expected to equal at least $1 million. The
Klaassens have the right to require Sunrise to file a registration statement
twice on Form S-1 and an unlimited number of times on Form S-3. However, Sunrise
is obligated to pay registration expenses only for the first two registrations
on Form S-3. If a demand registration is an underwritten public offering and the
managing underwriter advises Sunrise that the number of securities being
registered exceeds the
 
                                       110
<PAGE>   120
 
number of securities which can be sold without having a material adverse effect
on the offering, Sunrise may reduce the number of shares being registered by the
Klaassens.
 
     Incidental Registration.  In addition, the registration agreement provides
that if Sunrise at any time proposes to register any of its securities under the
Securities Act, on a form other than Form S-4 or S-8, the Klaassens are entitled
to have their shares included in such registration statement.
 
                                 LEGAL MATTERS
 
     The validity of the Sunrise common stock offered by this proxy statement/
prospectus, and the material federal income tax consequences of the
qualification of the merger as a reorganization within Section 368(a) of the
Internal Revenue Code, have been passed upon by Hogan & Hartson L.L.P,
Washington, D.C.
 
     The material federal income tax consequences of the merger have been passed
upon by Wachtell, Lipton, Rosen & Katz, New York, New York.
 
                                    EXPERTS
 
     Ernst & Young LLP, independent auditors, have audited the consolidated
financial statements of Sunrise included in its Annual Report on Form 10-K for
the year ended December 31, 1998, as set forth in their report, which is
incorporated by reference in this proxy statement/prospectus. Ernst & Young LLP,
independent auditors, have also audited the consolidated financial statements of
Karrington at December 31, 1998 and 1997 and for each of the three years in the
period ended December 31, 1998, included later in this proxy
statement/prospectus, as set forth in their report, which is also included later
in this proxy statement/prospectus. The consolidated financial statements of
both companies have been included in this proxy statement/prospectus in reliance
on Ernst & Young LLP's reports, given on their authority as experts in
accounting and auditing.
 
                             SHAREHOLDER PROPOSALS
 
     Karrington will hold a 1999 annual meeting of shareholders only if the
merger is not completed before the time of the annual meeting. If an annual
meeting is held, for shareholder proposals to be considered for inclusion in the
proxy statement for the 1999 annual meeting of shareholders of Karrington, the
proposals had to have been received by the secretary of Karrington no later than
December 11, 1998. Karrington did not receive any shareholder proposals for the
annual meeting.
 
                                 OTHER MATTERS
 
     As of the date of this proxy statement/prospectus, the board of directors
of Karrington does not know of any matter that will be presented for
consideration at the special meeting, other than as described in this proxy
statement/prospectus. If any other matters properly come before the special
meeting or any adjournment or postponement
 
                                       111
<PAGE>   121
 
of the special meeting and are voted upon, the individuals named as proxies will
exercise their discretionary authority to vote the shares represented by the
proxies as to any such matters, as recommended by the management of Karrington.
 
                         INDEPENDENT PUBLIC ACCOUNTANTS
 
     Representatives of Ernst & Young LLP are expected to be present at the
special meeting to respond to appropriate questions and to make such statements
as they may desire.
 
                      WHERE YOU CAN FIND MORE INFORMATION
 
     Sunrise has filed with the SEC a registration statement on Form S-4 under
the Securities Act that registers the distribution to Karrington shareholders of
the shares of Sunrise common stock to be issued in connection with the merger.
The registration statement on Form S-4, including the attached exhibits and
schedules, contain additional relevant information about Sunrise common stock.
The rules and regulations of the SEC allow us to omit particular information
included in the registration statement from this proxy statement/prospectus.
 
     In addition, Sunrise and Karrington file annual, quarterly and special

                           FORWARD-LOOKING STATEMENTS
 
     A number of statements contained or incorporated by reference in this proxy
statement/prospectus include forward-looking statements within the meaning of
the Private Securities Litigation Reform Act of 1995. All statements regarding
each of Sunrise's expected future financial position, business strategy,
projected costs and plans, and objectives of management for future operations
are forward-looking statements. In some cases, you can identify these so-called
"forward-looking statements" by words like "may," "will," "should," "expects,"
"plans," "anticipates," "believes," "estimates," "predicts," "potential," or
"continue" or the negative of those words and other comparable words. Although
Sunrise believes the expectations reflected in such forward-looking statements
are based on reasonable assumptions, no assurance can be given that such
expectations will prove to have been correct. Important factors that could cause
actual results to differ materially from the expectations reflected in the
forward-looking statements in this proxy statement/prospectus include, among
others, the factors set forth under the caption "risk factors," general economic
and business and market conditions, changes in laws and increased competitive
pressure in the company's industry.

                        PRO FORMA FINANCIAL INFORMATION
 
     The following unaudited pro forma condensed combined financial statements
are based upon the historical consolidated financial statements of Sunrise and
Karrington adjusted to give effect to the acquisition of Karrington by Sunrise
under the purchase method of accounting consistent with Accounting Principles
Board Opinion No. 16. The total estimated purchase price of Karrington is
approximately $94.9 million.
 
     The unaudited pro forma combined statement of operations for the year ended
December 31, 1998 is based upon the historical consolidated statement of
operations of Sunrise adjusted to give effect to: (1) the purchase of four
separate first trust mortgages secured by Karrington properties from Meditrust
Corporation for cash, and (2) the assignment of Sunrise's rights to acquire six
properties leased by Karrington from Meditrust to a trust owned and financed by
financial institutions, and leasing of the six properties by Sunrise. Sunrise's
historical consolidated statement of operations and Karrington's historical
consolidated statement of operations were then adjusted to give effect to the
acquisition of Karrington by Sunrise.
 
     The unaudited pro forma condensed combined balance sheet at December 31,
1998 was prepared as if the transaction above were consummated as of December
31, 1998. The unaudited pro forma combined statement of operations for the year
ended December 31, 1998 was prepared as if the above transactions were
consummated on January 1, 1998.
 
     This information should be read in conjunction with the notes and the
consolidated financial statements of Sunrise incorporated by reference in this
proxy statement/prospectus and the consolidated financial statements and notes
of Karrington included in this proxy statement/prospectus. The unaudited pro
forma condensed combined financial data do not represent what Sunrise's results
of operations or financial position actually would have been had such
transactions and events occurred on the dates specified, or project Sunrise's
results of operations or financial position for any future period or date. The
pro forma adjustments are based upon available information and adjustments that
management of Sunrise believes are reasonable. In the opinion of management of
Sunrise, all adjustments have been made that are necessary to present the pro
forma condensed combined data.
 
     A preliminary allocation of the purchase price has been made to major
categories of assets and liabilities in the accompanying pro forma financial
statements based on available information. The actual allocation of purchase
price and the resulting effect on income from operations may differ
significantly from the pro forma amounts included in this proxy
statement/prospectus. These pro forma adjustments represent the Company's
preliminary determination of purchase accounting adjustments and are based upon
available information and assumptions that Sunrise believes to be reasonable.
Consequently, the amounts reflected in the pro forma financial statements are
subject to change, and the final amounts my differ substantially.

     (A) On December 2, 1998, Sunrise purchased four first trust mortgages,
which are secured by Karrington properties, from Meditrust Corporation for cash
as previously reported on Form 8-K dated December 2, 1998 and filed with the SEC
on December 17, 1998. Represents an adjustment to eliminate Sunrise's investment
in Karrington's mortgage debt in connection with the merger, as follows:

     (B) On December 2, 1998, Sunrise assigned its right to purchase six
properties owned by Meditrust Corporation and leased by Karrington to a trust
owned and funded by financial institutions (the "Trust"). As such, the Trust
purchased the six properties from Meditrust Corporation for approximately $42.2
million. Simultaneously, Sunrise entered into an operating leasing arrangement
with the Trust to lease the six properties. The lease term is three years.
Sunrise has guaranteed the payment of all obligations under the lease. There are
no extension options, however, Sunrise has the option 120 days prior to the
expiration date of the lease of either purchasing or selling all the leased
properties. If Sunrise exercises its option to sell the properties and the
proceeds from the sale exceed the obligations under the lease, then Sunrise is
entitled to the excess. However, if the proceeds from the sale are less than the
obligations under the lease, then Sunrise is obligated to fund the difference.
Sunrise is responsible for the payment of real estate taxes, insurance and other
operating expenses. The lease requires Sunrise to maintain specified coverage
ratios, liquidity and net worth. The operating subleases with Karrington expire
in May 2010. Future minimum lease payments under this lease as of December 31,
1998, for 1999, 2000 and 2001 are $3,492, $3,492 and $44,091, respectively. This
transaction was previously reported on Form 8-K dated December 2, 1998 and filed
with the SEC on December 17, 1998.
 
     In connection with the closing of the lease arrangement, Meditrust released
$2.1 million of Karrington escrow deposits to Sunrise. This entry is a pro forma
elimination of these escrow balances resulting from the merger.
 
     (C) The adjustments to record the merger as a purchase transaction are
based upon the assumed purchase price of $94,897, assuming a market value of
$37.625 per share of Sunrise common stock on March 4, 1999, the closing price of
Sunrise common stock on the effective date of amendment no. 1 to the merger
agreement. The exchange ratio of 0.3333 to 1 was used in calculating the number
of shares of Sunrise common stock to be issued in connection with the merger.
The Karrington stock options were valued using the Black-Scholes option
valuation model.

     Operating facilities were valued at the estimated stabilized net operating
income discounted at capitalization rates currently experienced by Sunrise in
other recent transactions. Adjustments were made for known cash outflows related
to each property. Sunrise has utilized this methodology to determine amounts it
is willing to pay for the purchase of other assisted living facilities and
believes it to represent a valid determination of the amount at which an
assisted living facility could be exchanged in a current transaction between
willing parties, other than in a forced sale or liquidation. Allocations of
overall value between land, building and equipment are based upon averages of
other properties developed by Sunrise and Karrington. No value was assigned to
accounts receivable-due from REIT and related accounts payable because such
values were reflected in connection with the acquisition of Meditrust interests.
All other tangible assets and liabilities of Karrington were valued at
Karrington's historical carrying value which approximates fair value because of
the short-term nature of those items.
 
     Deferred income taxes were estimated as the difference between tax basis
and estimated fair value of assets and liabilities, other than goodwill, at
Sunrise's estimated effective tax rate of 40%.
 
     The remaining cost of the transaction in excess of the estimated assigned
value of specifically identified assets is assumed to be goodwill.
 
     (E) To adjust Karrington's historical assets and liabilities to fair value,
to eliminate assets and liabilities which would be eliminated in connection with
the merger and to record merger costs as follows:

     (G) Represents an adjustment to eliminate Sunrise's note receivable with
Karrington.
 
     (H) Represents an adjustment to reclassify Sunrise's Historical deficit
interests in unconsolidated assisted living facilities of $1,003 from a
liability to an asset to conform with the Sunrise Pro Forma Combined
presentation.
 
     (I) Sunrise intends to sell 17 facilities included in the Karrington
portfolio within 12 months following completion of the merger. Sunrise believes
that these properties do not coincide with Sunrise's strategy. Specifically,
Sunrise believes such properties are not located within its target markets,
cannot be easily repositioned as Sunrise assisted living facilities and would
not be able to achieve benefits of regional clustering. Consequently, the
estimated fair value less the estimated costs to sell of these assets is
presented as assets held for sale on the balance sheet.
 
     Further, the operating results of these facilities are as follows:

     (J) Represents net decrease in depreciation of property and equipment and
amortization of intangibles as the result of recording Karrington's property,
equipment, and intangibles at fair value versus historical cost and using
Sunrise's estimated useful lives. Depreciation and amortization is computed on a
straight-line basis over the estimated useful lives of the related assets based
on the respective dates each asset was placed in service. Buildings have been
depreciated over 40 years and equipment over 5 years. The useful lives of the
intangibles were determined based upon the weighted average useful lives of the
underlying asset or agreements which gave rise to such intangibles.
 
     The calculation of depreciation of property and equipment and amortization
of intangibles assets for the year ended December 31, 1998 is as follows.
Because the dates placed in service vary with respect to property and equipment,
leaseholds and management contracts, depreciation and amortization for each
respective period can not be recalculated using only the data provided in the
following table.

     The following is a calculation of interest earned by Sunrise on its
investment in Karrington mortgages (see Note A above). Interest income generated
by Sunrise would be equal to Karrington's historical interest expense on these
mortgages for the respective periods. The premium on the mortgages of $252 is
amortized on a straight line basis of the weighted average months to maturity of
129.

                         REPORT OF INDEPENDENT AUDITORS
 
TO THE SHAREHOLDERS OF KARRINGTON HEALTH, INC.
 
     We have audited the accompanying consolidated balance sheets of Karrington
Health, Inc. and subsidiaries (the "Company") as of December 31, 1998 and 1997,
and the related consolidated statements of operations, equity, and cash flows
for each of the three years in the period ended December 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Karrington Health, Inc. and subsidiaries as of December 31, 1998 and 1997, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended December 31, 1998 in conformity with
generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
1.  DESCRIPTION OF THE BUSINESS
 
     The Company is a developer, owner and operator of licensed, assisted living
residences which provides quality professional, personal and health-care
services, including an emphasis on Alzheimer's care, for individuals needing
assistance with activities of daily living. These activities include bathing,
dressing, meal preparation, housekeeping, taking medications, transportation,
and other activities that, because of the residents' conditions, are difficult
for residents to accomplish in an independent living setting. The Company offers
its customers a dignified residential environment focused on quality of life.
The Company also provides development, support and management services to its
joint ventures and others in the long-term care industry. As of December 31,
1998, the Company, including joint ventures, had 40 residences open in Ohio,
Michigan, Pennsylvania, Indiana, Illinois, Minnesota, North Carolina, North
Dakota, Iowa, Colorado and New Mexico and 10 residences under construction in
Ohio, Minnesota, North Carolina and Michigan.
 
     Karrington Health, Inc. was incorporated in April 1996 to become the parent
of Karrington Operating Company (Karrington Operating) upon the consummation of
the reorganization transactions which occurred immediately prior to the
effective date of the registration statement (see Note 9). Hereinafter, all
references to the "Company" encompass Karrington Operating and Karrington
Health, Inc. Karrington Operating was an Ohio General Partnership founded in
1991 by DevelopMed Associates, Inc. (Associates) and JMAC Properties, Inc., a
private investment company, the principal shareholder of which is JMAC, Inc.
(JMAC). Effective December 31, 1996, the net assets of Karrington Operating and
three other related partnerships were distributed to new subsidiary corporations
of Karrington Health, Inc. The trade name "Karrington Communities," a Registered
Trademark, is the operating name of all residences owned and operated by the
Company.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
     The consolidated financial statements reflect the operations and
development activities of the Company, including all wholly-owned subsidiaries
and a majority-owned entity. Significant intercompany transactions and accounts
are eliminated in consolidation. The minority interests on the December 31, 1998
balance sheet and in the 1998 statement of operations represent a 30% interest
in an assisted living residence located in Chicago, Illinois that opened in
October 1998. The Company owns a 70% controlling interest in the project that it
developed, constructed and manages. Accordingly, the Company consolidates the
balance sheet and results of operations of this residence.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
              FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
DISCLOSURES ABOUT SEGMENTS
 
     The Company is required to adopt the disclosure provisions of Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information," as of December 31, 1998. The Company has
determined that it has just one reportable segment as described in Note 1.
 
USE OF 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 assets and liabilities,
disclosures of contingent assets and liabilities and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from the estimates.
 
INVESTMENT IN UNCONSOLIDATED ENTITIES
 
     The Company uses the equity method of accounting for its investments in its
19.9%-50% jointly-owned ventures, which were formed to operate assisted living
residences (see Note 7).
 
REVENUE RECOGNITION
 
     The Company recognizes assisted living service fee revenue in the period in
which it is earned. Payments received in advance are reflected as unearned
resident fees in the accompanying consolidated financial statements. Community
fees are payments received from residents at move in and may be refundable
ratably over three months from the date of admission if the resident moves out.
Community fees are recognized as revenue when received less an estimate of the
amount that may be refunded. The Company performs development and project
management consulting services for its joint ventures and recognizes revenue for
these fees as the services are provided.
 
CASH EQUIVALENTS
 
     The Company considers all liquid investments purchased with a maturity of
three months or less to be cash equivalents. The carrying value of cash
equivalents approximates their fair value.
 
RECEIVABLES DUE FROM LESSOR
 
     Pursuant to the Company's lease commitments (see Note 6), funds provided by
the lessor for costs to develop and construct assisted living residences are
used by the

Company to pay the related construction costs. The Company does not have the
legal right to offset construction payables against amounts due from the lessor.
Accordingly, receivables due from the lessor represent construction costs
incurred that have not yet been reimbursed by the lessor.
 
PROPERTY
 
     Property and equipment are recorded at cost. In connection with the
development of residence projects, the Company has entered into land purchase
contracts, agreements with architects, financing agreements and construction
contracts which are administered by the Company. All costs related to the
development of residences are capitalized during the construction period.
Indirect project development and pre-acquisition costs are allocated to projects
and also are capitalized. Depreciation is computed when assets are placed in
service, using the straight-line method over the respective useful lives of each
class of asset which generally are as follows:

UNUSUAL CHARGES
 
     During the third quarter of 1997, the Company recorded an unusual charge of
approximately $1.4 million which primarily related to a $1.2 million charge as a
result of a decision to abandon certain projects. The Company's property and
equipment includes costs related to acquisition and development of projects in
process, including capitalized costs associated with the Company's development
department. At the time a project is abandoned, all previously capitalized costs
are expensed. The remaining charges primarily relate to severance costs
associated with third quarter resignations.

              FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
ORGANIZATION AND PRE-OPENING COSTS
 
     Organization costs are amortized using the straight-line method over five
years.
 
     Pre-opening costs include costs to hire and train staff, costs to prepare
the residence for operation and other related costs incurred prior to opening.
Costs incurred in connection with preparing the residence for opening and
initial occupancy are capitalized and amortized over one year commencing with
the opening of the residence.
 
     In April 1998, the Accounting Standards Executive Committee issued SOP
98-5, "Reporting on the Costs of Start-Up Activities" which requires that the
costs of start-up activities and organization costs be expensed as incurred. SOP
98-5 is effective for fiscal years beginning after December 15, 1998 with
earlier application encouraged. Management will apply the provisions of the SOP
in the first quarter of 1999. The application of SOP 98-5 will require the
Company to write-off all existing deferred preopening and organization costs
($1.9 million at January 1, 1999) and expense all such items as incurred on a
prospective basis.
 
DEFERRED FINANCING COSTS
 
     Financing costs are capitalized and amortized using the interest method
over the term of the related financing.
 
ADVERTISING EXPENSE
 
     The Company records advertising expenditures in accordance with the
provisions of AICPA SOP 93-7, "Reporting on Advertising Costs," which requires
advertising expenditures to be expensed as incurred. Advertising expenditures
were approximately $1,328,000, $709,000 and $424,000 for 1998, 1997 and 1996,
respectively.
 
INCOME TAXES
 
     Partnership taxable income and losses were allocated to the partners for
inclusion in their respective income tax returns. Accordingly, no provision or
benefit for income taxes was recorded prior to July 18, 1996 (see Note 8).
 
NET LOSS PER COMMON SHARE
 
     Net loss per common share - basic and diluted for 1998 and 1997 is computed
based on the weighted average number of shares outstanding during the period as
the effect of including any common share equivalents would be antidilutive.
Common share equivalents are comprised of outstanding stock options. For 1996,
the Company had a proforma net loss per share of $0.48. The proforma net loss
per share - basic and diluted

for 1996 is computed based on the weighted average number of shares outstanding
during 1996 based on 4,350,000 common shares outstanding following the
reorganization (described in Note 9) and the 2,350,000 common shares issued as a
result of the Company's initial public offering in July 1996.
 
RECLASSIFICATIONS
 
     Certain 1997 and 1996 balances have been reclassified to conform to the
1998 presentation.
 
3.  ACQUISITION
 
     On April 30, 1997, the Company completed the acquisition, except for one
entity which was completed on July 1, 1997, of Kensington Management Group, Inc.
and affiliates (Kensington) of Golden Valley, Minnesota. Kensington operates
innovative Alzheimer's care communities under the name Kensington Cottages which
provide Alzheimer's care programs using medical directors with geriatric and
dementia specialties. As of December 31, 1998, Kensington had 12 residences open
and four residences complete and being readied to open for a total of 523 beds
in three states.
 
     The aggregate purchase price approximated $28 million, including cash, the
issuance of 137,363 of the Company's common shares, and approximately $22
million in new and assumed bank debt financing. The number of common shares
issued was determined by dividing $1.5 million by the average closing price of
the Company's common shares for the fifteen trading days ending with the third
business day prior to closing. The transaction was accounted for using the
purchase method of accounting. Accordingly, the Company began including the
operating results of Kensington in its consolidated statement of operations
subsequent to April 30, 1997 for seven of the entities and after July 1, 1997
for the remaining entity.
 
     The acquired assets were recorded at fair value based on appraisals.
Assumed liabilities were recorded at the present value of amounts to be paid.
Goodwill related to the acquisition of approximately $8.4 million is being
amortized using the straight-line method over 40 years.
 
     The following unaudited proforma consolidated results of operations for the
years ended December 31, 1997 and 1996 reflect the proforma effects of the
Kensington acquisition as if such transaction had occurred at the beginning of
the years presented below. The unaudited proforma information does not purport
to be indicative of the Company's results of operations that actually would have
occurred had the acquisition of

and 2011 for six residences, five of which opened in 1998. These leases provide
for renewal periods and additional lease payments based on increased revenues
during specified periods. The leases require the Company to maintain minimum
current ratios and net worth requirements and respective residences to maintain
specific debt service coverage ratios. The Company is responsible for the
payment of real estate taxes, site maintenance, and access road maintenance.

              FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
     In the second quarter of 1998, the Company sold six assisted living
residences for approximately $39.3 million and leased them back under a 20-year
master lease agreement which includes two ten-year renewal options. All six home
leases will be co-terminus and option periods must be exercised for all or none
of the residences. The transaction resulted in a gain of approximately $9.5
million, which was deferred and is being amortized over the initial lease
period. The proceeds of the transaction were used to repay mortgage debt of
$26.4 million and short-term debt of $3.5 million. The balance of the proceeds
was used for development activities and working capital needs.
 
     The Company also leases vehicles and certain office equipment for periods
up to five years and two land only leases that include renewal options and
expire in 2018 and 2026. Future minimum lease payments under noncancellable
operating leases are as follows:

6.  NOTES PAYABLE AND LONG-TERM OBLIGATIONS
 
     Notes payable at December 31, 1998 represent amounts outstanding under two
lines of credit arrangements. In March 1997, the Company entered into a $5
million line of credit expiring in May 1999. At December 31, 1998, there was $5
million outstanding under this agreement. Interest is payable monthly and, at
the Company's option, accrues at the bank's prime rate or LIBOR rate plus .75%.
Pursuant to the amended merger agreement discussed in Note 12, Sunrise has made
available to the Company a $16.5 million line of credit to be used for
construction and development activities and working capital which expires in
January 2000. Interest is payable monthly and accrues at 10%. At December 31,
1998, there was $5.3 million outstanding under this agreement. The weighted
average interest rates for short-term borrowings were 7.3% for 1998 and 7.8% for
1997.

     The mortgage loans are collateralized by substantially all the assets of
each residence. Certain of the mortgage agreements require the respective
residences to maintain specified debt service coverage ratios and consolidated
minimum current ratios and net worth requirements. Certain lenders also require
escrow balances to be held by the lenders which are included in other assets in
the Company's consolidated balance sheets.
 
MORTGAGES PAYABLE
 
     Meditrust Mortgage Investments, Inc., an affiliate of Meditrust (a large
health care REIT) provided mortgage and lease financing subject to various terms
and conditions. The financings, which were entered into on a
residence-by-residence basis, are for terms of up to 14 years (with two
additional five-year extension periods for the lease transactions). Interest
during construction accrued at 2% above the prime rate. On completion of each
residence, payments are set at an amount equal to 3.25% over the yield at that
time on the ten-year U.S. Treasury notes. Additional interest or lease payments
are contingent on increased revenues of a financed residence during specified
periods. At December 31, 1998, the Company was in violation of net worth and
current ratio covenants, which the lender has waived through the end of 1999.
The Company has

completed mortgage agreements for four residences totaling $22.4 million and six
operating lease transactions totaling $46.2 million. The amounts outstanding
under the four mortgage agreements totaled $22.1 million at December 31, 1998.
See Note 12.
 
     On April 30, 1997, the Company entered into a $27.6 million promissory note
in conjunction with its acquisition of Kensington (see Note 3) and the build out
of nine Kensington cottages on the Rochester, Minnesota campus. Interest accrues
at 10% and is payable monthly. Principal and interest installments are payable
monthly (based on a 25-year amortization period) beginning in September 1999
through April 2007 at which time the entire outstanding principal balance
becomes due. The amount outstanding under the agreement was approximately $19.9
million as of December 31, 1998. The remaining amounts were to be disbursed in
two phases at such time that the nine cottages and certain other Kensington
properties achieved specified debt service coverage ratios. The Company's
decision not to open four of the remaining Rochester cottages until later in
1999 prevents the Company from accessing $5.9 million of the remaining $7.7
million of additional funds. The Company is currently in the process of
negotiating an extension that will allow the Company to achieve the necessary
fill-up to meet the required minimum debt service coverage ratios.
 
     In October 1997, the Company entered a $10.3 million construction loan
agreement for the development and construction of three assisted living
residences. Interest is payable monthly and accrues at the bank's prime rate
plus 1 1/2% during construction. In October 1999, the Company may elect, at its
option, to convert the construction loan into a term loan maturing in October
2004. Principal and interest payments under the term loan would be based on a
25-year amortization schedule with interest accruing at either prime plus 1 1/2%
or an amount equal to 3.0% over the yield at the time on five-year U.S. Treasury
notes. The Company is required to maintain minimum net worth and current ratio
amounts and, if the term loan is elected, to maintain debt service coverage
ratios with respect to individual residences. At December 31, 1998, the Company
was in violation of net worth, tangible net worth and current ratio covenants,
which the lender has waived through the end of 1999. As of December 31, 1998,
there was $7.4 million outstanding under this agreement.
 
     In early 1998, the Company entered into two construction loan agreements
totaling $20.1 million. Interest is payable monthly and accrues at LIBOR plus
2.75% or prime plus  1/2%. The Company is required to maintain minimum net worth
and tangible net worth amounts with respect to one of the loan agreements ($6.9
million of total). At December 31, 1998, the Company was in violation of its
tangible net worth covenant which the lender has waived through the end of 1999.
In December 2000, the Company may elect, at its option, to extend the agreements
up to two additional years. Principal and interest payments under the extension
periods would be based on 25-year

amortization schedules with interest accruing at variable rates. As of December
31, 1998, there was $19.3 million outstanding under these agreements.
 
     The remaining $14.0 million of mortgages outstanding at December 31, 1998
primarily represent various single facility agreements with various lenders for
seven residences.
 
REVENUE BOND
 
     In July 1996, the Company entered into a $5.8 million residential rental
development revenue bond with the Allegheny County Industrial Development
Authority. Interest on the bonds is determined weekly, although the Company has
the option to convert the bonds to a term note. While the bonds are in the
weekly rate mode, the bondholders have the option to tender their bonds for
redemption. Any bonds tendered are subject to a remarketing agreement that is
secured by a letter of credit.
 
PROMISSORY NOTE
 
     In September 1997, the Company entered into a $7.5 million promissory note
with JMAC, Inc., a 33% shareholder of the Company. Interest is payable monthly
and accrues at a bank's prime rate. In addition, the Company has obtained a
commitment from JMAC, Inc. which provides up to $4 million for working capital
needs. Such commitment terminates upon the earlier of the closing of the Sunrise
transaction discussed in Note 12 or January 1, 2000.
 
     Other long-term liabilities primarily represent amounts paid to the Company
by the lessor under certain operating lease agreements. These amounts, which are
not required to be repaid, are deferred and amortized over the term of the
respective leases.
 
     Interest costs incurred were $7,466,000, 5,110,000 and $2,309,000 for the
years ended December 31, 1998, 1997 and 1996, respectively. Of these amounts
$1,583,000, $2,367,000 and $1,038,000 were capitalized to
construction-in-progress in the respective periods. Interest costs incurred
include amounts due under obligations to JMAC and amounted to $660,000, $190,000
and $175,000 in 1998, 1997 and 1996, respectively.
 
     The carrying amounts of long-term obligations approximate fair value as the
interest rates are self-adjusting or are comparable to rates currently
available.

7.  INVESTMENT IN UNCONSOLIDATED ENTITIES
 
     The Company and Sisters of Charity Health Care Systems, Inc. of Cincinnati,
Ohio (a founding system of Catholic Health Initiatives ("CHI")), have entered
into six joint venture agreements to develop, own and operate seven assisted
living residences in Ohio, New Mexico and Colorado, six of which were open at
December 31, 1998. Each project is jointly owned by the Company and CHI, with
the Company typically owning approximately 20% of the equity of the project.
Construction and permanent debt financing generally is to be arranged by CHI on
behalf of the venture and is to be non-recourse to the Company. The Company
provides all development and management services with respect to each residence
under a standard agreement that generally provides for a development fee of
$250,000 per project and a management fee of 5% of revenues.
 
     Under the agreements with CHI, the Company earned and recorded as revenue
development fees of $198,000, $241,000 and $464,000 in 1998, 1997 and 1996,
respectively. The Company serves as manager for each of the residences and
receives management fees upon commencement of operations. Management fees of
$501,000, $305,000 and $149,000 have been recorded as revenues for the years
ended December 31, 1998, 1997 and 1996, respectively.
 
     Effective January 1, 1998, the Company entered into a joint venture
agreement with a local hospital to operate an assisted living residence in
Findlay, Ohio, which opened on December 31, 1997. The joint venture paid the
Company a fee of $300,000 for developing the assisted living residence. The
Company has entered into a management agreement with the joint venture which
provides for management fees equal to 6% of revenues. Beginning in the third
year of operations, the Company may earn a 2% incentive management fee if
certain performance criteria are met. The joint venture is owned 50% by the
Company and is accounted for using the equity method of accounting.

     Deferred income taxes arise from temporary differences between financial
reporting and tax reporting bases of assets and liabilities, and operating loss
carryforwards for tax purposes. The components of the deferred income tax assets
and liabilities are as follows:

9.  EQUITY
 
     At December 31, 1998, the Company's authorized capital shares consisted of
(a) 28,000,000 common shares, without par value, of which 6,839,368 were issued
and outstanding and (b) 2,000,000 non-voting preferred shares without par value,
none of which has been issued. The Company's Board of Directors has the
authority to issue preferred shares in one or more series and to fix the
designations, the number of shares in such series, liquidation preferences,
dividend rates, conversion rights and redemption provisions of the shares
constituting any series, without any further vote or action by the Company's
shareholders. Any series of preferred shares so issued could have priority over
the common shares with respect to dividend or liquidation rights or both.
 
     On July 18, 1996, 3,000,000 of the Company's common shares were sold
pursuant to its initial public offering. Of the total shares sold, 2,350,000
common shares were sold

by the Company and 650,000 common shares were sold by JMAC. The net proceeds to
the Company were approximately $27.5 million of which $5.7 million was used to
repay indebtedness due JMAC. The balance of the net proceeds was used to finance
the development and acquisition of additional assisted living residences and for
working capital and general corporate purposes.
 
     Immediately prior to July 18, 1996, the shareholders of JMAC Properties,
Inc. and Associates contributed the stock in their respective companies for
stock in the Company. The shareholder of JMAC Properties, Inc. received 66 2/3%
of the pre-offering outstanding common shares of the Company while the
shareholders of Associates received the remaining 33 1/3% (a total of 4,350,000
shares). Following the reorganization, JMAC Properties, Inc. and Associates
became wholly-owned subsidiaries of the Company. As a result, the Company owned
100% of the equity interests of Karrington Operating.
 
     Effective July 1, 1998, the Company issued 2,005 common shares to employees
pursuant to the 1996 Incentive Stock Plan discussed in Note 10.
 
     As part of the consideration for the Kensington acquisition (see Note 3)
the Company issued 137,363 common shares on April 30, 1997.
 
10.  INCENTIVE STOCK AND 401(k) PLANS
 
     The Company has adopted the 1996 Incentive Stock Plan (the "Plan"). The
Plan provides for the grant of incentive and non-qualified stock options, stock
appreciation rights, restricted stock, performance shares and unrestricted
common shares. The Plan also provides for the purchase of common shares through
payroll deductions by employees of the Company who have satisfied certain
eligibility requirements. The maximum number of shares available for issuance
under the Plan is 550,000.
 
     The Company has granted non-qualified options to certain officers, key
employees and non-employee directors. The employee options have a ten-year term
with 25% of the options vesting on each of the second through the fifth
anniversaries of the date of grant. Non-employee director options are
exercisable beginning six months after the effective date of grant with a
ten-year term. Each continuing non-employee director will receive on the day
after each annual meeting of shareholders, a grant of a non-qualified stock
option to purchase 2,000 common shares of the Company at an exercise price equal
to the fair market value of the shares on the date of grant.

     At December 31, 1998, the average remaining contractual life was 8.8 years
and 176,875 options were exercisable at a weighted average exercise price of
$12.22.
 
     In 1996, the Company adopted Statement of Financial Accounting Standards
(SFAS) No. 123, "Accounting for Stock-Based Compensation." The Statement allows
for a fair value-based method of accounting for employee stock options and
similar equity instruments. In accordance with the provisions of SFAS No. 123,
the Company has elected to account for options granted under the Plan in
accordance with APB Opinion 25, "Accounting for Stock Issued to Employees" and
related interpretations. If the Company had elected to recognize compensation
cost based on the fair value of options at the grant date as prescribed by SFAS
No. 123, pro forma net loss and pro forma net loss per common share - basic and
diluted for 1998, 1997 and 1996, respectively, would have been $15,597,000 and
$2.28, $5,965,000 and $.88, and $2,914,000 and $.54. The fair value for these
options was estimated at the date of grant using the Black-Scholes option
pricing model. The assumptions used in the model for 1998, 1997 and 1996,
respectively, included an expected dividend yield of 0%, 0% and 0%; an expected
stock price volatility of .53, .47 and .34; a risk-free interest rate of 4.7%,
6.0% and 6.5%; and an expected life of the options of 7 years, 2 or 7 years, and
10 years. The financial effects of applying SFAS No. 123 are not likely to be
representative of the effects on reported results of operations for future
years.
 
     In 1997, the Company established the Karrington Health, Inc. and Affiliates
401(k) Plan (the "401(k) Plan") for the benefit of eligible full-time employees
of the Company and its joint ventures. Eligible participants may contribute up
to 10% of their compensation to the 401(k) Plan and self-direct such
contributions. The Company may,

in its discretion, make annual matching and/or discretionary contributions on
behalf of each eligible participant which vest over a six year period. No
Company matching or discretionary contributions were expensed in 1998 or 1997.
 
11.  COMMITMENTS AND CONTINGENCIES
 
     The Company has commitments totaling approximately $3.8 million at
December 31, 1998 for various land purchase contracts and $9.7 million for
various construction contracts.
 
     In the third quarter of 1998, the Company sold two parcels of land in
California for a total of $3.5 million. No gain or loss resulted from this
transaction. The net proceeds to the Company were $2.4 million after paying off
a related note payable of approximately $1.1 million. The parties entered into a
Put and Escrow Agreement related to one of the parcels which states that if the
buyer, after exercise of reasonable diligence, is unable to obtain all final
permits, utility consents and approvals from three governmental agencies on or
before February 1, 1999, the buyer may exercise a "put" to require the Company
to purchase the parcel from the buyer. If the buyer should exercise the put, the
purchase price is $2,100,000 plus one-half (up to a maximum of $25,000) of the
buyer's out-of-pocket costs. As the put had not expired at December 31, 1998,
the Company reported the $2,100,000 purchase price on its balance sheet as "land
sold subject to put right" and "deposit on sale of land." The put was not
exercised and expired on March 1, 1999.
 
     In the ordinary course of business, the Company is threatened with or named
as a defendant in various litigation issues related to its operations. It is not
possible to determine the ultimate disposition of these matters. In the opinion
of management, the outcome of these actions will not significantly affect the
Company's financial position.
 
12.  AGREEMENT OF MERGER AND RELATED AGREEMENTS
 
     On October 18, 1998, the Company and Sunrise Assisted Living, Inc.
("Sunrise"), a provider of assisted living for seniors, entered into a
definitive agreement, as amended March 4, 1999, for Sunrise to acquire the
Company in a tax-free, stock-for-stock transaction valued at approximately $94.9
million.
 
     Under the merger agreement, as amended, the Company would become a wholly
owned subsidiary of Sunrise, and each issued and outstanding share of the
Company's common stock would be automatically converted into the right to
receive 0.3333 shares of Sunrise common stock. Sunrise expects to account for
the acquisition of the Company using the purchase method of accounting.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
              FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
     Pursuant to the amended merger agreement, Sunrise has made available to the
Company a $16.5 million line of credit to be used for construction and
development activities and working capital which expires in January 2000.
 
     After the merger, there will be approximately 21.7 million shares of
Sunrise common stock outstanding. The combined company will operate 115
communities in 19 states with a total resident capacity of approximately 8,746.
It also will have an additional 91 communities in various stages of development.
 
     The acquisition has been approved by the Boards of Directors of both
companies and requires the approval of the shareholders of the Company. The
transaction also is subject to certain other customary conditions, including
regulatory approvals, and is expected to be completed during the second quarter
of 1999.
 
     In December 1998, Sunrise executed an agreement with Meditrust and acquired
four separate first trust mortgages secured by the Company's properties and the
right to purchase six assisted living properties currently leased to the
Company.
 
     Effective January 1, 1999, the Company entered into agreements with Sunrise
to manage the Company's assisted living residences and to develop three new
assisted living properties. These agreements were entered into to facilitate the
post-merger integration of the Company's operations. Under the management
agreements, Sunrise receives a management fee of 7% of revenues.
 
13. RISKS AND UNCERTAINTIES
 
     For the three years ended December 31, 1998, net cash used in operations
totaled $12.6 million. The cash requirement reflects operating losses associated
with newly opened residences and increased general and administrative costs as
part of the Company's rapid growth plan over this period. Cash used by
operations will continue until such time as residences currently in the fill-up
phase become stable and generate enough net profits to absorb losses from
start-up residences.
 
     The Company currently plans to open approximately 16 new Company and
jointly-owned residences in 1999 and the second quarter of 2000. The Company has
existing financing in place in the form of loans or leases for seven of these
residences. Additional financing will be required for the remaining nine
residences, three of which are currently under construction, and to refinance
certain existing indebtedness. The Company has not been pursuing permanent
financing arrangements for the three residences under construction at the
request of Sunrise pending consummation of the proposed merger with Sunrise
described in Note 12. However, the Company continues to evaluate its financing
alternatives, including traditional mortgages and sale/leaseback transactions
which it has been successful in executing in the past.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
              FOR THE YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996
 
     The Company has been, and will continue to be, dependent on third party
financing for its acquisition and development program. There can be no assurance
that financing for the Company's development program will be available to the
Company on acceptable terms, if at all. Moreover, to the extent the Company
opens properties that do not generate positive cash flow, the Company may be
required to seek additional capital for working capital and liquidity purposes.
 
     Under the amended merger with Sunrise discussed in Note 12, Sunrise has
made available to the Company a $16.5 million line of credit to be used for
construction and development activities and working capital. The line of credit
expires in January 2000.
 
     In March 1999, the Company obtained a commitment from JMAC, Inc. which
provides up to $4 million for working capital needs. Such commitment terminates
upon the earlier of the closing of the Sunrise transaction discussed in Note 12
or January 1, 2000.
 
     The Company believes its existing financing commitments, including the
Sunrise line of credit, together with additional anticipated financing, will be
sufficient to fund its development, construction and working capital needs for
1999.

become effective at the time of filing of the Certificate of Merger with the
Secretary of State of the State of Ohio in accordance with the OGCL or at such
other time which the parties hereto shall have agreed upon and designated in

<PAGE>   167
 
     1.5   Articles of Incorporation and Bylaws.  At the Effective Time, the

applicable Law.
 
     1.6   Directors and Officers.  The persons set forth on Schedule 1.6(a)
hereto shall, after the Effective Time, serve as the directors of the Surviving
Corporation, to serve until their successors have been duly elected and

                                   ARTICLE II
 
               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES
 
     2.1   Share Consideration; Conversion or Cancellation of Shares in the
Merger. Subject to the provisions of this Article II, at the Effective Time, by
virtue of the Merger and without any action on the part of Merger Sub, the
Company or the holders of any of the following securities:
 
         (a) Each issued and outstanding share of Company Common Stock (other
     than shares of Company Common Stock to be canceled in accordance with
     Section 2.1(d)) shall be automatically converted into the right to receive
     (i) a number of shares of Acquiror Common Stock equal to the lesser of (A)
     0.3939; or (B) the number obtained by dividing $13.00 by the Average
     Trading Price of Acquiror Common Stock (as defined below) but in no event
     less than 0.3333 (the "Exchange Ratio"), plus (ii) the associated right to
     purchase shares of Series C Junior Participating Preferred Stock of
     Acquiror pursuant to that certain Rights Agreement dated as of April 25,
     1996 between Acquiror and First Union National Bank of North Carolina, as
     amended (the "Rights Agreement"). For purposes of the preceding sentence,
     the Average Trading Price of Acquiror Common Stock shall be equal to the
     average of the closing price of a share of Acquiror Common Stock as quoted
     on Nasdaq National Market for the ten (10) day trading period ending three
     trading days prior to the date of the Company Shareholders' Meeting. If,
     between the date of this Agreement and the Effective Time, Acquiror or the
     Company should split, subdivide, reclassify, recapitalize, combine or
     exchange their respective Common Stock, or pay a stock dividend or other
     stock distribution in their respective Common Stock, or otherwise change
     their respective Common Stock into a different number of shares, a
     different class or a different type of security, or make any other dividend
     or distribution on their respective Common Stock, then the Exchange Ratio
     will be appropriately adjusted to reflect such split, subdivision,
     reclassification, recapitalization, combination, exchange, dividend or
     other distribution or change. The Exchange Ratio shall be rounded, in each
     case, to the nearest ten-thousandth of a share.
 
                                       A-3
<PAGE>   168
 
         (b) All of the issued and outstanding shares of the Company Common
     Stock converted into Acquiror Common Stock pursuant to Section 2.1(a) (the
     "Company Shares") shall cease to be outstanding, shall automatically be
     canceled and retired and shall cease to exist, and each certificate
     representing any such shares shall thereafter only represent the right to
     receive for each of such shares, upon the surrender of such certificate by
     the holder thereof in accordance with Section 2.2(b), the amount of the
     Acquiror Common Stock specified above (the "Share Consideration") and cash
     in lieu of fractional shares of Acquiror Common Stock as contemplated by
     Section 2.4. The holders of such certificates previously evidencing such
     shares of Company Common Stock immediately prior to the Effective Time
     shall cease to have any rights with respect to such shares of Company
     Common Stock except as otherwise provided herein.
 
         (c) The issued and outstanding shares of the common stock, $.01 par
     value, of Merger Sub (the "Merger Sub Common Stock"), shall be converted
     into one hundred (100) shares of newly and validly issued, fully paid and
     nonassessable shares of common stock, without par value, of the Surviving
     Corporation ("Surviving Corporation Common Stock"), so that at and
     immediately following the Effective Time only such newly issued Surviving
     Corporation Common Stock will constitute all of the issued and outstanding
     capital stock of the Surviving Corporation.
 
         (d) All shares of Company Common Stock that are owned by the Company,
     Acquiror or any direct or indirect wholly owned subsidiary of Acquiror or
     of the Company immediately prior to the Effective Time shall automatically
     be canceled and retired and cease to exist, without any conversion thereof
     or payment with respect thereto, and no Acquiror Common Stock or other
     consideration shall be delivered in exchange therefor.
 
         (e) Each outstanding option to purchase Company Common Stock (each, a
     "Company Stock Option") shall be assumed by Acquiror in the manner provided
     in Section 5.7.
 
     2.2   Payment for Shares in the Merger.
 
     (a) As of the Effective Time, Acquiror shall enter into an agreement with a
bank or trust company selected by Acquiror and reasonably acceptable to the
Company as exchange agent for the Company Shares in accordance with this Article
II (the "Exchange Agent"), which shall provide that Acquiror shall deposit, or
shall cause to be deposited, with the Exchange Agent, for the benefit of those
persons who immediately prior to the Effective Time were the holders of Company
Shares, a sufficient number of certificates representing shares of Acquiror
Common Stock required to effect the delivery of the aggregate Share
Consideration required to be issued pursuant to Section 2.1 (the certificates
representing Acquiror Common Stock comprising such aggregate Share
Consideration, together with any dividends or distributions with respect thereto
with a record date after the Effective Time, being hereinafter referred to as
the "Exchange Fund"). The Exchange Agent shall, pursuant to irrevocable
instructions from Acquiror,
 
                                       A-4
<PAGE>   169
 
deliver the shares of Acquiror Common Stock contemplated to be issued pursuant
to Section 2.1 and, unless otherwise directed by the Acquiror in accordance with
Section 2.4(b), effect the sales provided for in Section 2.4(a) out of the
Exchange Fund. The Exchange Fund shall not be used for any other purpose.
 
     (b) As soon as reasonably practicable after the Effective Time, Acquiror
shall cause the Exchange Agent to mail to each holder of record of a certificate
or certificates which immediately prior to the Effective Time evidenced
outstanding Company Shares (the "Certificates"), (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon proper delivery of the Certificates to
the Exchange Agent and shall be in such form and have such other provisions as
Acquiror may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for certificates evidencing the Share
Consideration and cash in lieu of fractional shares, if any. Upon the surrender
of a Certificate for cancellation to the Exchange Agent, together with such
letter of transmittal duly completed and properly executed in accordance with
instructions thereto and such other customary documents as may be reasonably
required pursuant to such instructions, the holder of such Certificate shall be
entitled to receive in exchange therefor (X) certificates evidencing the number
of shares of Acquiror Common Stock that such holder has the right to receive
pursuant to Section 2.1(a), rounded down to the nearest whole share (after
taking into account all shares of Company Common Stock then held by such holder
under all such Certificates so surrendered), (Y) cash in lieu of fractional
shares of Acquiror Common Stock to which such holder is entitled pursuant to
Section 2.4 herein and (Z) any dividends or other distributions to which such
holder is entitled pursuant to Section 2.2(c) herein, the dividends,
distributions and cash described in clauses (Y) and (Z) being collectively
referred to as the "Other Amounts," and the surrendered Certificate shall
forthwith be canceled. Until so surrendered and exchanged, the Certificates
shall represent solely the right to receive the Share Consideration and the
Other Amounts, subject to any required withholding of taxes. If Share
Consideration for any Company Shares is to be issued to a person other than the
person in whose name the Certificates for such surrendered shares are
registered, it shall be a condition of the exchange that the person requesting
such exchange shall pay to the Exchange Agent any transfer or other taxes
required by reason of the issuance or delivery of such Share Consideration to a
person other than the registered holder of the Certificates surrendered or shall
establish to the satisfaction of Acquiror that such tax has been paid or is not
applicable. Unless prohibited by law, former stockholders of record of the
Company as of the Effective Time shall be entitled to vote, after the Effective
Time, at any meeting of Acquiror stockholders, the number of whole shares of
Acquiror Common Stock into which their respective Company Shares are converted,
regardless of whether such holders have exchanged their Certificates in
accordance with this Section 2.2.
 
     (c) No dividends or other distributions with respect to Acquiror Common
Stock with a record date after the Effective Time shall be paid to the holders
of any unsurrendered Certificate with respect to the shares of Acquiror Common
Stock represented thereby, and no part of the Share Consideration or Other
Amounts shall be
 
                                       A-5
<PAGE>   170
 
paid to any such holder, until the surrender of such Certificate in accordance
with this Section 2.2. Subject to the effect of applicable laws, following
surrender of any such Certificate, there shall be paid by Acquiror or the
Exchange Agent to the holder of the certificates evidencing whole shares of
Acquiror Common Stock issued in exchange therefor, in addition to the Share
Consideration to be issued in exchange therefor, without interest, (i) at the
time of such surrender, the amount of any cash payable in lieu of a fractional
share of Acquiror Common Stock to which such holder is entitled pursuant to
Section 2.4 and the amount of dividends or other distributions, with a record
date after the Effective Time theretofore paid with respect to such Share
Consideration, and (ii) at the appropriate payment date, the amount of dividends
or other distributions, with a record date after the Effective Time but prior to
such surrender and with a payment date subsequent to such surrender, payable
with respect to such Share Consideration.
 
     (d) All shares of Acquiror Common Stock issued and all cash paid upon the
surrender for exchange of the shares of Company Common Stock in accordance with
the terms hereof (including any cash paid pursuant to Sections 2.2(c) or 2.4)
shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Company Common Stock, subject, however, to the
Surviving Corporation's obligation to pay any dividends or make any other
distributions with a record date prior to the Effective Time which may have been
declared or made by the Company on such shares of Company Common Stock in
accordance with the terms of this Agreement or prior to the date of this
Agreement and which have been disclosed to Acquiror on the Company Disclosure
Schedule and which remain unpaid at the Effective Time, and there shall be no
further registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Company Common Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation, Acquiror or the
Exchange Agent for any reason, they shall be canceled and exchanged as provided
in this Article II.
 
     (e) In the event any Certificates shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by Acquiror,
the posting by such person of a bond in such amount, form and with such surety
as Acquiror may reasonably direct as indemnity against any claim that may be
made against it with respect to such Certificate, the Exchange Agent will issue
in exchange for such lost, stolen or destroyed Certificate the number of shares
of the Acquiror Common Stock and cash in lieu of fractional shares deliverable
(and unpaid dividends and distributions) in respect thereof pursuant to this
Agreement.
 
     (f) Acquiror, as the sole stockholder of Merger Sub, shall, upon surrender
to the Surviving Corporation of certificates representing the Merger Sub Common
Stock, receive a certificate representing the number of shares of the Surviving
Corporation Common Stock into which such Merger Sub Common Stock shall have been
converted pursuant to Section 2.1.
 
                                       A-6
<PAGE>   171
 
     (g) Certificates surrendered for exchange by any person constituting a
Company Affiliate (as defined in Section 5.12) shall not be exchanged for
certificates representing Acquiror Common Stock until Acquiror has received a
written agreement from such person as provided in Section 5.12.
 
     2.3   Exchange Agent.  Acquiror shall cause the Exchange Agent to agree,
among other things, that (i) the Exchange Agent shall maintain the Exchange Fund
as a separate fund to be held for the benefit of the holders of the Company
Shares, which shall be promptly applied by the Exchange Agent to making the
payments provided for in Section 2.2, (ii) any portion of the Exchange Fund that
has not been paid to holders of the Company Shares pursuant to Section 2.2 prior
to that date which is six months from the Effective Time shall be delivered to
Acquiror, and any holders of Company Shares who shall not have theretofore
complied with Section 2.2 shall thereafter look only to Acquiror for the Share
Consideration and Other Amounts; (iii) the Exchange Fund shall not be used for
any purpose that is not provided for herein, and (iv) all expenses of the
Exchange Agent shall be paid directly by Acquiror. Promptly following the date
which is six months from the Effective Time, the Exchange Agent shall return to
Acquiror all cash, securities and any other instruments in its possession
relating to the transactions described in this Agreement, and the Exchange
Agent's duties shall terminate. Thereafter, each holder of Certificates may
surrender such Certificates to Acquiror and (subject to applicable abandoned
property, escheat and similar laws) receive in exchange therefor the Share
Consideration payable with respect thereto, without interest, but shall have no
greater rights against Acquiror than may be accorded to general creditors of
Acquiror under the OGCL. The Exchange Agent shall not be entitled to vote or
exercise any rights of ownership with respect to the Acquiror Common Stock held
by it from time to time hereunder. None of Acquiror, Merger Sub, the Company,
the Exchange Agent, nor any of their respective officers, directors and
employees shall be liable to any holder of shares of Company Common Stock for
any Share Consideration or Other Amounts from the Exchange Fund delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law. The Exchange Agent shall invest any cash included in the Exchange
Fund, as directed by Acquiror, on a daily basis. Any interest and other income
resulting from such investments shall be paid to Acquiror.
 
     2.4   Fractional Shares.
 
     (a) No certificates or scrip evidencing fractional shares of Acquiror
Common Stock shall be issued upon the surrender for exchange of Certificates,
and any such fractional share interests will not entitle the owner thereof to
vote or to any rights of a stockholder of Acquiror. In lieu of any such
fractional shares, each holder of Company Shares who would otherwise have been
entitled to a fractional share of Acquiror Common Stock upon surrender of
Certificates for exchange pursuant to this Article II will be paid an amount in
cash (without interest), rounded to the nearest cent, equal to such holder's
proportionate interest in the Fractional Securities Fund (as defined below) or
as otherwise provided in Section 2.4(b). As promptly as practicable following
the Effective Time, the Exchange Agent shall determine the excess of (i) the
number of whole shares
 
                                       A-7
<PAGE>   172
 
of the Acquiror Common Stock delivered to the Exchange Agent by Acquiror
pursuant to Section 2.2(a) over (ii) the aggregate number of whole shares of the
Acquiror Common Stock to be distributed to holders of the Company Shares
pursuant to Section 2.2(b) (such excess being herein called the "Excess
Shares"), and the Exchange Agent, as agent for the holders of Company Shares,
unless otherwise directed by Acquiror pursuant to Section 2.4(b), shall sell the
Excess Shares at then prevailing prices on The Nasdaq National Market
("Nasdaq"), all in the manner provided in this Section 2.4(a). The sale of the
Excess Shares by the Exchange Agent shall be executed on Nasdaq and shall be
executed in round lots to the extent practicable. The Exchange Agent shall use
reasonable efforts to complete the sale of the Excess Shares as promptly
following the Effective Time as, in the Exchange Agent's sole judgment, is
practicable consistent with obtaining the best execution of such sales in light
of prevailing market conditions. Acquiror shall pay all commissions, transfer
taxes and other out-of-pocket transaction costs, including the expenses and
compensation of the Exchange Agent, incurred in connection with such sale of
Excess Shares. Until the net proceeds of such sale or sales have been
distributed to the holders of Company Shares, the Exchange Agent will hold such
proceeds in trust for such holders of Company Shares (the "Fractional Securities
Fund").
 
     (b) In lieu of establishing the Fractional Securities Fund pursuant to
Section 2.4(a), the Exchange Agent may, at the direction of Acquiror prior to
the Effective Time, pay any cash amounts due the former stockholders of the
Company directly from cash made available to the Exchange Agent by Acquiror for
such purpose, in which event, each holder of Company Shares who would otherwise
have been entitled to receive a fraction of a share of Acquiror Common Stock
(after taking into account all Certificates delivered by such holder) shall
receive, in lieu thereof, cash (without interest) in an amount equal to such
fractional part of a share of Acquiror Common Stock multiplied by the closing
price of a share of Acquiror Common Stock on the business day immediately
preceding the Closing Date as reported on Nasdaq.
 
     (c) As soon as practicable after the determination of the amount of cash to
be paid to holders of Company Shares in lieu of any fractional interests, the
Exchange Agent shall make available in accordance with this Agreement such
amounts to such holders.
 
     2.5   Further Assurances.  If, at any time after the Effective Time, the
Surviving Corporation shall consider or be advised that any further deeds, bills
of sale, assignments, assurances in law or any other acts or things are
necessary, desirable or proper (a) to vest, perfect or confirm, of record or
otherwise, in the Surviving Corporation, the title to or interest in any
property or right of the Company or Merger Sub acquired or to be acquired by
reason of, or as a result of, the Merger, or (b) otherwise to carry out the
purposes of this Agreement, the Company and Merger Sub agree that the Surviving
Corporation and its proper officers and directors shall and will execute and
deliver all such deeds, bills of sale, assignments and assurances in law and do
all acts or things necessary, desirable or proper to vest, perfect or confirm
title to or interest in such property or right in the Surviving Corporation and
otherwise to carry out the purposes of this Agreement, and that the proper
officers and directors of the Surviving Corporation
 
                                       A-8
<PAGE>   173
 
are fully authorized in the name of the Company and Merger Sub or otherwise to
take any and all such action.
 
                                  ARTICLE III
 
           REPRESENTATIONS AND WARRANTIES OF ACQUIROR AND MERGER SUB
 
     On or prior to the date hereof, Acquiror has delivered to the Company a
schedule (the "Acquiror Disclosure Schedule") setting forth, among other things,
items the disclosure of which is necessary or appropriate either (i) in response
to an express disclosure requirement contained in a provision hereof or (ii) as
an exception to one or more representations or warranties contained in Article
III or to one or more of its covenants contained in Article V; provided that the
mere inclusion of an item in the Acquiror Disclosure Schedule as an exception to
a representation or warranty shall not be deemed an admission by the Acquiror
that such item represents a material exception or fact, event or circumstance or
that such item is reasonably likely to result in a Material Adverse Effect on
Acquiror. Acquiror and Merger Sub, jointly and severally, represent and warrant
to the Company in each case, as of the date of this Agreement that, except as
set forth in the Acquiror Disclosure Schedule, which shall identify exceptions
by specific Section references:
 
     3.1   Organization.  Each of Acquiror, Merger Sub and Acquiror's
subsidiaries (the "Acquiror Subsidiaries") has been duly organized and is
validly existing and in good standing (with respect to jurisdictions which
recognize such concept) under the laws of the jurisdiction of its organization,
has all requisite power and authority to own, operate and lease its properties
and to carry on its business as it is now being conducted, and is qualified or
licensed to do business and is in good standing (with respect to jurisdictions
which recognize such concept) in each jurisdiction in which the nature of the
business conducted by it or the ownership or leasing of its properties makes
such qualification necessary, other than where the failure to be so qualified or
licensed, individually or in the aggregate, would not have a Material Adverse
Effect on Acquiror. The term "Material Adverse Effect on Acquiror" as used in
this Agreement shall mean any change or effect that, individually or when taken
together with all such other changes or effects, is or would reasonably be
expected to be materially adverse to the financial condition, results of
operations, properties or business of Acquiror and the Acquiror Subsidiaries
taken as a whole; provided, however, that Material Adverse Effect on Acquiror
shall not be deemed to include the impact of (i) changes in general economic
conditions or conditions applicable to the assisted living industry generally,
(ii) changes or effects which result from the execution and delivery of this
Agreement or the consummation of any transactions contemplated hereby, or (iii)
the events set forth in Section 3.1 of the Acquiror Disclosure Schedule. True
and complete copies of the Restated Certificate of Incorporation ("Acquiror
Restated Certificate of Incorporation") and the Amended and Restated Bylaws of
Acquiror (the "Acquiror Bylaws") have heretofore been delivered to the Company,
and such Acquiror Restated Certificate of Incorporation and Acquiror Bylaws are
in full force and effect. True and complete copies
 
                                       A-9
<PAGE>   174
 
of the Articles of Incorporation and the Code of Regulations of Merger Sub have
heretofore been delivered to the Company, and such Articles of Incorporation and
Code of Regulations are in full force and effect. Section 3.1 of the Acquiror
Disclosure Schedule contains a complete and accurate list of all of the Acquiror
Subsidiaries, a list of the jurisdictions where Acquiror and each of the
Acquiror Subsidiaries is duly qualified or licensed to do business as a foreign
organization and Acquiror's percentage ownership in each such Acquiror
Subsidiary. Neither Acquiror nor any Acquiror Subsidiary is in violation of any
provision of its articles or certificate of incorporation or bylaws (each as may
have been amended or restated) or other organizational documents, as the case
may be. Merger Sub was formed solely for the purpose of engaging in the
transactions contemplated by this Agreement. As of the date hereof and the
Effective Time, except for obligations or liabilities incurred in connection
with its incorporation or organization and the transactions contemplated by this
Agreement and except for this Agreement and any other agreements or arrangements
contemplated by this Agreement, Merger Sub has not and will not have incurred,
directly or indirectly, through any subsidiary or affiliate, any liabilities or
obligations or engaged in any business activities of any type or kind whatsoever
or entered into any agreements or arrangements with any person.
 
     3.2   Capitalization.  As of the date of this Agreement, the authorized
capital stock of Acquiror consists of (i) 60,000,000 shares of Common Stock, par
value $0.01 per share ("Acquiror Common Stock") and (ii) 10,000,000 shares of
preferred stock, $.01 par value ("Acquiror Preferred Stock"), of which 30,000
shares of the Acquiror Preferred Stock have been designated as "Series C Junior
Participating Preferred Stock." As of October 16, 1998, (i) 19,383,210 shares of
Acquiror Common Stock were issued and outstanding, all of which were duly
authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights created by statute, the Acquiror Restated Certificate of
Incorporation or the Acquiror Bylaws or any agreement to which Acquiror is a
party or by which Acquiror is bound and (ii) no shares of Acquiror Common Stock
were held in the treasury of Acquiror. As of the date of this Agreement, no
shares of Acquiror Preferred Stock are issued and outstanding. Each of the
outstanding shares of capital stock of Acquiror were issued in compliance with
all applicable Federal and state laws concerning the issuance of securities. As
of the date of this Agreement, 4,667,678 shares of Acquiror Common Stock are
reserved for future issuance pursuant to employee stock options granted pursuant
to Acquiror's stock option plans described in Section 3.2 of the Acquiror
Disclosure Schedule (the "Acquiror Option Plans") and certain other option
arrangements (any stock option so issued being a "stock option"). In addition to
the foregoing, 4,033,613 shares of Acquiror Common Stock are reserved for
issuance upon conversion of Acquiror's $150,000,000 principal amount of
aggregate outstanding 5.5% Convertible Subordinated Notes Due 2002 (the
"Acquiror Notes"). As of the date of this Agreement, the authorized capital of
Merger Sub consists of 850 shares of common stock, without par value per share,
of which 100 shares are issued and outstanding and were duly authorized, validly
issued, fully paid and nonassessable and not subject to preemptive rights
created by statute, Merger Sub's Articles of Incorporation or Code of
Regulations or any agreement to which Merger Sub
 
                                      A-10
<PAGE>   175
 
is a party or by which Merger Sub is bound. Acquiror has heretofore delivered to
the Company a correct and complete copy of the Acquiror Option Plans. Except as
set forth in this Section 3.2 or in Section 3.2 of the Acquiror Disclosure
Schedule, there are no options, warrants, puts, calls or other rights (including
registration rights), agreements, arrangements or commitments of any character
to which Acquiror or any Acquiror Subsidiary is a party or by which any of them
is bound relating to the issued or unissued capital stock of, or other equity
interests in, Acquiror or any Acquiror Subsidiary or obligating Acquiror or any
Acquiror Subsidiary to grant, issue, deliver or sell, or cause to be granted,
issued, delivered or sold, any shares of capital stock of, or other equity
interests in, Acquiror or any Acquiror Subsidiary, by sale, lease, license or
otherwise. All shares of Acquiror Common Stock subject to issuance as aforesaid,
upon issuance on the terms and conditions specified in the instruments pursuant
to which they are issuable, will be duly authorized, validly issued, fully paid
and nonassessable and will not have been issued in violation of or subject to
any preemptive rights created by statute, the Acquiror Restated Certificate of
Incorporation or Acquiror Bylaws or any agreement to which Acquiror is a party
or by which Acquiror is bound. Except as set forth in this Section 3.2, in
Section 3.2 of the Acquiror Disclosure Schedule, or in the Acquiror Current
Reports (as defined in Section 3.11), there are no outstanding contractual
obligations, contingent or otherwise, of Acquiror or any Acquiror Subsidiary to
repurchase, redeem or otherwise acquire any shares of Acquiror Common Stock or
any capital stock of, or other equity interests in, any Acquiror Subsidiary.
There are no agreements, arrangements or commitments of any character
(contingent or otherwise) pursuant to which any person is or may be entitled to
receive any of the revenues or earnings, or any payment based thereon or
calculated in accordance therewith, of Acquiror or any Acquiror Subsidiary. Each
outstanding share of capital stock of, or other equity interest in, each
Acquiror Subsidiary is duly authorized, validly issued, fully paid and
nonassessable and, except as set forth in Section 3.2 of the Acquiror Disclosure
Schedule, each such share or other equity interest owned by Acquiror or another
Acquiror Subsidiary is owned free and clear of all security interests, liens,
claims, charges, pledges, options, rights of first refusal, agreements,
conditions, restrictions, limitations on voting rights, charges, decrees,
judgments, and other encumbrances or imperfections of title of any nature
whatsoever ("Encumbrances"). Except for the capital stock of the Acquiror
Subsidiaries and except for the ownership interests set forth in Section 3.2 of
the Acquiror Disclosure Schedule, Acquiror does not own, directly or indirectly,
any capital stock or other ownership interest in, or any interest convertible
into or exchangeable or exercisable for capital stock of or other ownership
interest in, any person. Acquiror is not aware of any voting trust, stockholder
agreement or other similar arrangement relating to any shares of Acquiror Common
Stock.
 
     3.3   No Adjustment Under Notes.  No event has occurred or failed to occur
that has resulted in an adjustment to the original conversion price under the
Acquiror Notes.
 
     3.4   Options or Other Rights.  Except as disclosed in Section 3.2 herein
or in the Acquiror SEC Filings (as defined in Section 3.12), as of the date of
this Agreement, there is no outstanding right, subscription, warrant, call,
unsatisfied preemptive right, option or other agreement or arrangement of any
kind to purchase or otherwise to
 
                                      A-11
<PAGE>   176
 
receive from Acquiror or any Acquiror Subsidiary any of the outstanding
authorized but unissued, unauthorized or treasury shares of the capital stock or
any other security of Acquiror or any Acquiror Subsidiary, and there is no
outstanding security of any kind convertible into or exchangeable for such
capital stock. Except as set forth in Section 3.4 of the Acquiror Disclosure
Schedule or the Acquiror SEC Filings, there are no agreements or understandings
among Acquiror or any Acquiror Subsidiary on the one hand and any other person
on the other hand concerning the registration of any security of Acquiror or an
Acquiror Subsidiary under the Securities Act (as defined below).
 
     3.5   Authority Relative to this Agreement.
 
     (a) Acquiror has all requisite corporate power and authority to execute and
deliver this Agreement, to perform its obligations hereunder and to consummate
the transactions contemplated hereby to be consummated by Acquiror. The

                                      A-13
<PAGE>   178
 
approvals, authorizations or permits, or to make such filings or notifications
would not, either individually or in the aggregate, prevent Acquiror or Merger
Sub from performing any of their respective obligations under this Agreement and
would not have a Material Adverse Effect on Acquiror.
 
     3.8   Compliance with Laws.
 
     (a) As of the date of this Agreement, each of Acquiror and the Acquiror
Subsidiaries holds all licenses, certificates of need ("CONs"), franchises,

including, without limitation, the requirements, guidelines, rules and
regulations of Medicare, Medicaid, CHAMPUS, state approved Medicaid waiver
programs and other third-party reimbursement programs, except where the failure
to hold such Acquiror Permits or to so comply or perform, individually or in the
aggregate, would not have a Material Adverse Effect on Acquiror. No Acquiror
Permits will in any way be affected by, or terminate or lapse by reason of, the
transactions contemplated by this Agreement.
 
     (b) To Acquiror's knowledge, all health care personnel employed by Acquiror
or any Acquiror Subsidiary are properly licensed to the extent required to
perform the duties of their employment in each jurisdiction where such duties

Schedule, no action or proceeding is pending or, to Acquiror's knowledge,
threatened that may result in the suspension, revocation or termination of any
Acquiror Permit, the issuance of any cease-and-desist order, or the imposition
of any administrative or judicial sanction, and neither Acquiror nor any
Acquiror Subsidiary has received any notice from any governmental authority in
respect of the suspension, revocation or termination of any Acquiror Permit, or
any notice of any intention to conduct any investigation or institute any
proceeding, in any such case where such suspension, revocation, termination,
order, sanction, investigation or proceeding could result, individually or in
the aggregate, in a Material Adverse Effect on Acquiror.
 
     (d) Neither Acquiror nor any Acquiror Subsidiary has received notice that
Medicare, Medicaid, CHAMPUS, state approved Medicaid waiver programs or any
other third-party reimbursement program has any claims for disallowance of costs
against any of them which could result in offsets against future reimbursement
or recovery of prior payments, which offsets or recoveries, individually or in
the aggregate, would have a Material Adverse Effect on Acquiror.
 
                                      A-14
<PAGE>   179
 
     (e) Acquiror and the Acquiror Subsidiaries have filed all forms, reports,
statements, and other documents required to be filed with any Governments
Entities, including, without limitation, state insurance and state and federal
health regulatory authorities and reimbursement programs, except where the
failure to file such forms, reports, statements or other documents under this
Section 3.8(e) would not have a Material Adverse Effect on Acquiror.
 
     3.9   Fraud and Abuse Matters.  Neither Acquiror nor any Acquiror
Subsidiary, nor the officers, directors, employees or agents of any of Acquiror
or any Acquiror Subsidiary, have engaged in any activities which are prohibited,
or are cause for civil penalties or mandatory or permissive exclusion from
Medicare, Medicaid, or any other State Health Care Program (as defined in
Section 1128(h) of the federal Social Security Act ("SSA")) or Federal Health
Care Program (as defined in Section 1128B(f) of the SSA) under sec.sec. 1320a-7,
1320a-7a, 1320a-7b, or 1395nn of Title 42 of the United States Code, the federal

private accrediting organization from which Acquiror or any Acquiror Subsidiary
seeks accreditation or by generally recognized professional standards of care or
conduct, including but not limited to the following activities:
 
         (a) knowingly and willfully making or causing to be made a false
     statement or representation of a material fact in any application for any
     benefit or payment;
 
         (b) knowingly and willfully making or causing to be made any false
     statement or representation of a material fact for use in determining
     rights to any benefit or payment;

     (b) Section 3.10(b) of the Acquiror Disclosure Schedule contains a list of
each existing Medicare and Medicaid contract (the "Acquiror Program Agreements")
or evidence thereof relating to the participation by Acquiror and the Acquiror

compliance with all material terms, conditions and provisions of the Acquiror
Program Agreements except
 
                                      A-16
<PAGE>   181
 
where the failure to comply would not have a Material Adverse Effect on
Acquiror. Except as set forth in Section 3.10(b) of the Acquiror Disclosure
Schedule, (i) no notice of any offsets against future reimbursement has been
received by Acquiror or any Acquiror Subsidiary, nor to the knowledge of
Acquiror, is there any reasonable basis therefor with respect to the
Governmental Programs except with respect to offsets in the ordinary course of
business which could not, individually or in the aggregate, reasonably be
expected to result in a Material Adverse Effect on Acquiror, (ii) there are no
pending appeals, adjustments, challenges, audits, litigation, notices of intent
to reopen or open completed payments with respect to the Governmental Programs
except such adjustments made in the ordinary course of business which could not,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Effect on Acquiror, and (iii) neither Acquiror nor any Acquiror
Subsidiary has received notice of pending, threatened or possible
decertification or other loss of participation in any of the Governmental
Programs which remains in effect as of the date hereof. Section 3.10(b) of the
Acquiror Disclosure Schedule lists any material contracts between Acquiror or
any Acquiror Subsidiary and third party payors, copies of which have been made
available to Acquiror. Acquiror and each of the Acquiror Subsidiaries, as
applicable, are in compliance in all material respects with all of the terms,
conditions and provisions of the contracts referenced in the immediately
preceding sentence.
 
     3.11   Litigation.  As of the date of this Agreement, except as may be
disclosed in the Acquiror 10-K (as defined below), reports filed on Forms 10-Q
or 8-K or proxy statements filed on Schedule 14A for periods subsequent to the
period covered by such Acquiror 10-K, in each case filed prior to the date
hereof (such reports and filings, collectively, the "Acquiror Current Reports"),
or except as set forth in Section 3.11 of the Acquiror Disclosure Schedule,
there is no claim, litigation, suit, arbitration, mediation, action, proceeding,
unfair labor practice complaint or grievance pending or, to Acquiror's
knowledge, investigation of any kind, at law or in equity (including actions or
proceedings seeking injunctive relief), pending or, to Acquiror's knowledge,
threatened in writing against Acquiror or any Acquiror Subsidiary or with
respect to any property or asset of any of them, except for claims, litigations,
suits, arbitrations, mediations, actions, proceedings, complaints, grievances or
investigations which, individually or in the aggregate, (a) would not have a
Material Adverse Effect on Acquiror, (b) would not impair in any material
respect the ability of Acquiror or any Acquiror Subsidiary to perform its
obligations under this Agreement or any other document contemplated hereby or
thereby or (c) would not prevent the consummation by Acquiror or any Acquiror
Subsidiary of any of the transactions contemplated by this Agreement or any
other document contemplated hereby or thereby. Neither Acquiror nor any Acquiror
Subsidiary nor any property or asset of any of them is subject to any continuing
order, judgment, settlement agreement, injunction, consent decree or other
similar written agreement with or, to Acquiror's knowledge, continuing
investigation by, any Governmental Entity, or any judgment, order, writ,
injunction, consent decree or award of any Governmental Entity or arbitrator,
including, without limitation, cease-and-desist or other orders, except for such
matters which (a) would not reasonably be expected to have a Material Adverse
Effect on Acquiror, (b) would not impair in any material respect the
 
                                      A-17
<PAGE>   182
 
ability of Acquiror or Merger Sub to perform its obligations under this
Agreement or (c) would not prevent the consummation by Acquiror or Merger Sub of
the transactions contemplated by this Agreement.
 
     3.12   Financial Statements and Reports.  Acquiror has made available to
the Company true and complete copies of (a) its Annual Report on Form 10-K for
the year ended December 31, 1997 (the "Acquiror 10-K") as filed with the
Securities and Exchange Commission (the "Commission"), (b) its proxy statement
relating to the annual meeting of its stockholders held on April 28, 1998; (c)
all registration statements filed by Acquiror and declared effective under the
Securities Act (other than registration statements on Form S-8), and (d) all
other reports, statements and registration statements (including Quarterly
Reports on Form 10-Q and Current Reports on Form 8-K but excluding preliminary
material and reports pursuant to Sections 13(d) or 13(g) of the Exchange Act)
filed by it with the Commission other than registration statements on Form S-8.
The reports, statements and registration statements referred to in the
immediately preceding sentence (including, without limitation, any financial
statements or schedules or other information, included or incorporated by
reference therein) are referred to in this Agreement as the "Acquiror SEC
Filings." As of the respective times such documents were filed or, as
applicable, were effective, the Acquiror SEC Filings complied as to form in all
material respects with the requirements of the Securities Act or the Exchange
Act, as the case may be, and the rules and regulations promulgated thereunder,
and except to the extent that information contained in any Acquiror SEC Filings
has been revised or superseded by a later Acquiror SEC Filing filed and publicly
available prior to the date of this Agreement, did not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. The financial
statements of Acquiror included in the Acquiror SEC Filings complied as of their
respective dates of filing with the Commission as to form in all material
respects with applicable accounting requirements and with the published rules
and regulations of the Commission with respect thereto, were prepared in
accordance with generally accepted accounting principles (as in effect from time
to time) applied on a consistent basis during the periods involved (except as
may be indicated therein or in the notes thereto or, in the case of the
unaudited interim financial statements, as permitted by Form 10-Q of the
Commission) and present fairly the consolidated financial position, consolidated
results of operations and consolidated cash flows of Acquiror and the Acquiror
Subsidiaries as of the dates and for the periods indicated, except (i) in the
case of unaudited interim consolidated financial statements, to normal recurring
year-end audit adjustments and any other adjustments described therein and (ii)
any pro forma financial information contained therein is not necessarily
indicative of the consolidated financial position of Acquiror and the Acquiror
Subsidiaries as of the respective dates thereof and the consolidated results of
operations and cash flows for the periods indicated. No Acquiror Subsidiary is
required to file any form, report or other document with the Commission. Except
as set forth in the Acquiror Current Reports, and except for liabilities and
obligations incurred in the ordinary course of business consistent with past
practice, since
 
                                      A-18
<PAGE>   183
 
the date of the most recent consolidated balance sheet included in the Acquiror
Current Reports, neither Acquiror nor any Acquiror Subsidiary has any
liabilities or obligations of any nature (whether accrued, absolute, contingent
or otherwise) required by generally accepted accounting principles to be
recognized or disclosed on a consolidated balance sheet of Acquiror and the
Acquiror Subsidiaries or in the notes thereto which could reasonably be expected
to have a Material Adverse Effect on Acquiror. The pro forma financial
information (and related notes thereto) included in the Acquiror SEC Filings
present fairly the information shown therein and were prepared, as of the
respective dates of filing of the Acquiror SEC Filings with the Commission, in
accordance with the Commission's rules and guidelines with respect to pro forma
financial statements. The necessary pro forma adjustments have been properly
applied to the historical amounts in the compilation of such pro forma financial
information, the assumptions used in the preparation thereof are reasonable and
the adjustments used therein are appropriate to give effect to the transactions
and circumstances referred to therein.
 
     3.13   Absence of Certain Changes or Events.  Other than as disclosed in
the Acquiror Current Reports or in Section 3.13 to the Acquiror Disclosure
Schedule, since June 30, 1998 and through the date of this Agreement, the
business of Acquiror and of each of the Acquiror Subsidiaries has been conducted
in the ordinary course, and there has not been (i) any Material Adverse Effect
on Acquiror; or (ii) any split, combination or reclassification of any of the
capital stock of Acquiror.
 
     3.14   Employee Benefit Plans and Employment Matters.
 
     (a) Section 3.14(a) of the Acquiror Disclosure Schedule lists all employee
benefit plans, collective bargaining agreements, labor contracts, and employment
agreements not otherwise disclosed in the Acquiror Current Reports in which
Acquiror or any Acquiror Subsidiary participates, or by which any of them are
bound, including, without limitation, (i) any profit sharing, deferred
compensation, bonus, stock option, stock purchase, pension, welfare, and
incentive plan or agreement; (ii) any plan providing for "fringe benefits" to
their employees, including, but not limited to, vacation, sick leave, medical,
hospitalization and life insurance; (iii) any written employment agreement and
any other employment agreement not terminable at will; and (iv) any other
"employee benefit plan" (within the meaning of Section 3(3) of the Employment
Retirement Income Security Act of 1974 ("ERISA")). Acquiror and the Acquiror
Subsidiaries are in compliance in all material respects with the requirements
prescribed by all Laws currently in effect applicable to employee benefit plans
and to any employment agreements, including, but not limited to, ERISA and the
Code. Acquiror and the Acquiror Subsidiaries have each performed all of its
obligations under all such employee benefit plans and employment agreements in
all material respects. There is no pending or, to the knowledge of Acquiror,
threatened legal action, proceeding or investigation against or involving any
Acquiror or Acquiror Subsidiary employee benefit plan which could result in a
material amount of liability to such employee benefit plan or to Acquiror, other
than routine claims for benefits involving less than $100,000 for each such
routine claim and $250,000 for all such routine claims in the aggregate.
 
                                      A-19
<PAGE>   184
 
     (b) Neither Acquiror nor the Acquiror Subsidiaries sponsor or participate
in, and have not sponsored or participated in, any employee pension benefit plan
to which Section 4021 of ERISA applies that would create a material amount of
liability to Acquiror under Title IV of ERISA.
 
     (c) Neither Acquiror nor the Acquiror Subsidiaries sponsor or participate
in, and have not sponsored or participated in, any employee benefit pension plan
that is a "multiemployer plan" (within the meaning of Section 3(37) of ERISA).
 
     (d) All group health plans of Acquiror and the Acquiror Subsidiaries have
been operated in compliance with the group health plan continuation coverage
requirements of Section 4980B of the Code in all material respects, to the
extent such requirements are applicable.
 
     (e) There have been no acts or omissions by Acquiror or any Acquiror
Subsidiary or by any fiduciary, disqualified person or party in interest with
respect to an employee benefit plan of Acquiror or any Acquiror Subsidiaries
that have given rise to or could reasonably be expected to give rise to a
material amount of fines, penalties, taxes, or related charges under Sections
502(c), 502(i) or 4071 of ERISA or under Chapter 43 of the Code.
 
     (f) No "reportable event," as defined in ERISA Section 4043, other than
those events with respect to which the Pension Benefit Guaranty Corporation has
waived the notice requirement, has occurred with respect to any of the employee
benefit plans of Acquiror.
 
     (g) Acquiror has furnished the Company with true and correct copies of all
plan documents and employment agreements referred to on the Acquiror Disclosure
Schedule, including all amendments thereto, and all related summary plan
descriptions to the extent that one is required by Law.
 
     (h) For purposes of this Section 3.14, any reference to "Acquiror" shall be
deemed to include a reference to any entity that is aggregated with Acquiror
under the provisions of Section 414 of the Code, to the extent that those
aggregation rules apply to any representation made herein.
 
     3.15   Labor Matters.  Except as disclosed in Section 3.15 of the Acquiror
Disclosure Schedule, neither Acquiror nor any Acquiror Subsidiary is a party to
any collective bargaining agreement with respect to any of their employees. None
of the employees of Acquiror or any Acquiror Subsidiary is represented by any
labor union. To the knowledge of Acquiror, there is no activity involving any
employees of Acquiror or the Acquiror Subsidiaries seeking to certify a
collective bargaining unit or engaging in any similar organizational activity.
 
     3.16   Insurance.  Acquiror and the Acquiror Subsidiaries maintain
insurance against such risks and in such amounts as Acquiror reasonably believes
are necessary to conduct its business. Acquiror and the Acquiror Subsidiaries
are not in default with respect to any provisions or requirements of any such
policy, nor have any of them failed
 
                                      A-20
<PAGE>   185
 
to give notice or present any claim thereunder in a due and timely fashion,
except for defaults or failures which, individually or in the aggregate, would
not have a Material Adverse Effect on Acquiror. Neither Acquiror nor any
Acquiror Subsidiary has received any notice of cancellation or termination in
respect of any of its insurance policies.
 
     3.17   Environmental Matters.  Except as disclosed on Section 3.17 of the
Acquiror Disclosure Schedule:
 
         (a) Acquiror and the Acquiror Subsidiaries have complied and are in
     compliance with, and the real property owned, operated, leased or used by
     Acquiror or the Acquiror Subsidiaries as of June 30, 1998, any additional
     real property owned, operated, leased or used since that date, and, for
     purposes of this Section 3.17, any real property formerly owned or operated
     by Acquiror or any Acquiror Subsidiary (collectively, the "Acquiror Real
     Property") and all improvements thereon are in compliance with, all
     Environmental Laws (as defined in Section 8.9(e)), except for such
     non-compliance as would not have a Material Adverse Effect on Acquiror and
     would not be considered "material" under the federal securities laws.
 
         (b) Neither Acquiror nor any Acquiror Subsidiary has any liability
     under any Environmental Law, nor is Acquiror or any Acquiror Subsidiary
     responsible by contract, by operation of law, otherwise for any liability
     of any other person under Environmental Law, which either individually or
     in the aggregate would have a Material Adverse Effect on Acquiror or would
     be considered "material" under the federal securities laws. Except for
     matters which would not have a Material Adverse Effect on Acquiror and
     would not be considered "material" under the federal securities laws, there
     are no pending or threatened actions, suits, orders, claims, legal
     proceedings or other proceedings based on, and neither Acquiror nor any
     Acquiror Subsidiary, nor any officer, director or stockholder thereof has
     directly or indirectly received any formal or informal notice of any
     complaint, order, directive, citation, notice of responsibility, notice of
     potential responsibility, or information request from any Governmental
     Entity or any other person or entity or knows or suspects any fact(s) which
     might reasonably form the basis for any such actions or notices arising out
     of or attributable to: (i) the current or past presence, Release (as
     defined in Section 8.9(j)), or threatened Release of Hazardous Materials
     (as defined in Section 8.9(f)) at or from any part of the Acquiror Real
     Property; (ii) the off-site disposal or treatment of Hazardous Materials
     originating on or from the Acquiror Real Property or the businesses or
     assets of Acquiror or any Acquiror Subsidiary; or (iii) any violation of
     Environmental Laws at any part of the Acquiror Real Property or arising
     from Acquiror's or any Acquiror Subsidiary's activities (or the activities
     of Acquiror's or any Acquiror Subsidiary's predecessors in title) involving
     Hazardous Materials.
 
         (c) Except as disclosed in Section 3.17(c) of the Acquiror Disclosure
     Schedule, Acquiror and the Acquiror Subsidiaries have been duly issued, and
     currently have and will maintain through the Closing Date, all permits,
     licenses,
 
                                      A-21
<PAGE>   186
 
     certificates and approvals required under any Environmental Law, each of
     which is valid and in full force and effect. Except in accordance with such
     permits, licenses, certificates and approvals, there has been no Release of
     material regulated by such permits, licenses, certificates or approvals at,
     on, under, or from the Acquiror Real Property.
 
         (d) Neither Acquiror nor any Acquiror Subsidiary has provided to any
     Governmental Entity, as required by Law, notice of any Release from any
     underground improvements, including but not limited to treatment or storage
     tanks, or underground piping associated with such tanks, used currently or
     in the past for the management of Hazardous Materials. No portion of the
     Acquiror Real Property is or has been used as a dump or landfill or
     consists of or contains filled in land or wetlands.
 
         (e) No Encumbrance in favor of any person relating to or in connection
     with any demand, claim, action or cause of action, assessment, loss, damage
     (including, without limitation, diminution in value), liability, cost and
     expense (including, without limitation, interest, penalties and attorneys'
     fees and disbursements) (collectively "Claims") under any Environmental Law
     has been filed or has attached to the Acquiror Real Property.
 
     3.18   Tax Matters.  Neither Acquiror nor, to the knowledge of Acquiror,
any of its affiliates has taken or agreed to take any action that would, nor
does Acquiror have any knowledge of any fact or circumstance that is reasonably
likely to, prevent the Merger from qualifying as a reorganization under the
provisions of Section 368(a) of the Code. Acquiror has paid, or made provision
in accordance with generally accepted accounting principles on its balance sheet
at December 31, 1997 included in the Acquiror 10-K, for all federal, state,
local, foreign or other governmental income, franchise, payroll, F.I.C.A.,
unemployment, withholding, real property, personal property, sales, payroll,
disability and all other taxes imposed on Acquiror or any Acquiror Subsidiary or
with respect to any of their respective properties, or otherwise payable by
them, including interest and penalties, if any, in respect thereof
(collectively, "Acquiror Taxes"), for the Acquiror taxable period ended December
31, 1997 and all fiscal periods of Acquiror prior thereto, except such
nonpayment, or failure to make provision, which, individually or in the
aggregate, would not have a Material Adverse Effect on Acquiror. Acquiror Taxes
paid and/or incurred from December 31, 1997 until the Closing Date shall include
only Acquiror Taxes incurred in the ordinary course of business. Acquiror and
each of the Acquiror Subsidiaries have timely filed all returns, reports and
certifications related to Acquiror Taxes which Acquiror and/or such Acquiror
Subsidiary (as the case may be) are required to file ("Acquiror Tax Returns"),
and have paid or provided for all the amounts shown to be due thereon, except
where such failure to make such timely filings, individually or in the
aggregate, would not have a Material Adverse Effect on Acquiror, and except for
the nonpayment of such amounts which, individually or in the aggregate, would
not have a Material Adverse Effect on Acquiror. Neither Acquiror nor any
Acquiror Subsidiary (i) has filed or entered into, or is otherwise bound by, any
currently effective election, consent or extension agreement that extends any
applicable statute of
 
                                      A-22
<PAGE>   187
 
limitations with respect to taxable periods of Acquiror, (ii) is a party to any
contractual obligation requiring the indemnification or reimbursement of any
person with respect to the payment of any Acquiror Taxes, other than among
Acquiror and the Acquiror Subsidiaries, or (iii) has received any claim by an
authority in a jurisdiction where neither Acquiror nor any Acquiror Subsidiary
files Acquiror Tax Returns that they are or may be subject to Acquiror Taxes by
that jurisdiction, except for any such claims as, individually or in the
aggregate, would not have a Material Adverse Effect on Acquiror. No action or
proceeding is pending or, to Acquiror's knowledge, threatened orally to any
Acquiror officer or in writing by any governmental authority for any audit,
examination, deficiency, assessment or collection from Acquiror or any Acquiror
Subsidiary of any Acquiror Taxes, no unresolved claim for any deficiency,
assessment or collection of any Acquiror Taxes has been asserted against
Acquiror or any Acquiror Subsidiary, and all resolved assessments of Acquiror
Taxes have been paid or are reflected on the Acquiror balance sheet at December
31, 1997 included in the Acquiror 10-K, except for any of the foregoing which,
individually or in the aggregate, would not have a Material Adverse Effect on
Acquiror.
 
     3.19   Intellectual Property.  Except as disclosed in Section 3.19 of the
Acquiror Disclosure Schedule, Acquiror and the Acquiror Subsidiaries own, or are
licensed or otherwise possess or have all necessary rights to use all patents,
trademarks, trade names, service marks, copyrights and any applications
therefor, net lists, schematics, technology, know-how, trade secrets, inventory,
ideas, algorithms, processes, computer software programs and applications (in
both source code and object code form), and tangible or intangible proprietary
information or material ("Intellectual Property") which is used in the conduct
of their respective businesses (collectively, "Acquiror Intellectual Property
Rights"). To the knowledge of Acquiror, neither Acquiror nor any Acquiror
Subsidiary is infringing or otherwise violating the intellectual property rights
of any person which infringement or violation would subject Acquiror or any
Acquiror Subsidiary to liabilities which, individually or in the aggregate,
would have a Material Adverse Effect on Acquiror or which would prevent Acquiror
or any Acquiror Subsidiary from conducting their respective businesses
substantially in the manner in which they are now being conducted. No claim has
been made or, to Acquiror's knowledge, threatened against Acquiror or any
Acquiror Subsidiary alleging any such violation. To the knowledge of Acquiror,
there is no unauthorized use, disclosure, infringement or misappropriation of
any Acquiror Intellectual Property Rights or any Intellectual Property right of
any third party to the extent licensed by or through Acquiror, by any third
party, including any employee or former employee of Acquiror, that could
reasonably be expected to have a Material Adverse Effect on Acquiror. Acquiror
is not, nor will it be as a result of the execution and delivery of this
Agreement or the performance of it obligations under this Agreement, in breach
of any license, sublicense or other agreement relating to the Acquiror
Intellectual Property Rights or Third Party Intellectual Property Rights (as
defined in Section 8.9(l)). Acquiror has not advised any third party that such
third party may be infringing any Acquiror Intellectual Property Rights or
breaching any license or agreement involving Acquiror Intellectual Property
Rights that could reasonably be expected to have a Material Adverse Effect on
Acquiror.

     3.20   No Default.  Except as set forth in Section 3.20 of the Acquiror
Disclosure Schedule, neither Acquiror nor any of the Acquiror Subsidiaries is in
default or violation (and no event has occurred which with or without notice or
the lapse of time or both would constitute a default or violation) of any term,
condition or provision of (i) its certificate or articles of incorporation or
bylaws or other organizational documents, (ii) any Laws applicable to Acquiror
or any Acquiror Subsidiary or by which any of their respective properties is
bound or affected, or (iii) any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which Acquiror or any Acquiror Subsidiary is a party or by which Acquiror or
any Acquiror Subsidiary or any of their respective properties or assets is bound
or affected, except in the case of clauses (ii) and (iii) above for defaults or
violations which would not have a Material Adverse Effect on Acquiror.
 
     3.21   Title to Properties; Encumbrances.  Section 3.21 of the Acquiror
Disclosure Schedule sets forth all real property owned or leased by Acquiror and
the Acquiror Subsidiaries (the "Acquiror Real Property"), indicating which
facilities are owned and which are leased. Except as disclosed in the Acquiror
Current Reports and as described in clause (ii) below: (i) each of Acquiror and
the Acquiror Subsidiaries has good, valid and marketable title to, or a valid
leasehold interest in, as applicable, all of its properties and assets (real,
personal and mixed, tangible and intangible), including, without limitation, all
Acquiror Real Property and all other properties and assets reflected in the
consolidated balance sheet of Acquiror and the Acquiror Subsidiaries at June 30,
1998 included in the Acquiror Form 10-Q for the quarter ended June 30, 1998
(except for properties and assets disposed of in the ordinary course of business
and consistent with past practice since June 30, 1998) and (ii) none of such
properties or assets are subject to any liability, obligation, claim, lien,
mortgage, pledge, security interest, conditional sale agreement, charge or
encumbrance of any kind (whether absolute, accrued, contingent or otherwise),
except for liens securing repayment of indebtedness incurred in the ordinary
course consistent with past practice subsequent to June 30, 1998 and liens for
taxes not yet due and payable, unrecorded and undelivered mortgages between a
Acquiror Subsidiary and a joint venture entity in which Acquiror is a limited
partner or a managing member (as identified in Section 3.21 of the Acquiror
Disclosure Schedule) and easements and restrictions of record, if any, which are
not substantial in amount, do not materially detract from the value of the
property or assets subject thereto and do not impair the operations of Acquiror
and the Acquiror Subsidiaries. Each of the leases is in full force and effect
and there is no default by landlord or tenant existing thereunder (and no event
has occurred which, with or without notice or the passage of time or both, would
constitute a default under such lease) which would have a Material Adverse
Effect on Acquiror. Except as set forth in Section 3.21 of the Acquiror
Disclosure Schedule, Acquiror and the Acquiror Subsidiaries have obtained
owner's title insurance on all of the Acquiror Real Property owned by Acquiror
or any Acquiror Subsidiary, in each case insuring good and marketable fee simple
title to such Acquiror Real Property, in an amount at least equal to the
aggregate value of such Acquiror Real Property together with all improvements
thereon. Except as would not cause a Material Adverse Effect on Acquiror, all of
the properties and assets of Acquiror and the Acquiror
 
                                      A-24

Subsidiaries are in good operating condition and repair, and maintenance thereon
has not been deferred beyond industry standards, and are suitable for the
purposes for which they are presently being used.
 
     3.22   Brokers.  Neither Acquiror nor any Acquiror Subsidiary has paid or
is obligated to pay any brokerage, finder's or other fee or commission to any
broker, finder, investment banker or other intermediary in connection with this
Agreement, except that Acquiror has retained Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ") as its financial advisor for the transactions
contemplated hereby, pursuant to an engagement letter a copy of which (as
executed by all the parties thereto) has been provided previously to the
Company.
 
     3.23   Opinion of Financial Advisor.  The Board of Directors of the
Acquiror has received the opinion of DLJ to the effect that, as of the date of
this Agreement, the consideration to be paid to the holders of shares of Company
Common Stock pursuant to this Agreement is fair to Acquiror, from a financial
point of view, a written copy of which (as executed) will be provided to the
Company promptly after receipt thereof by the Acquiror.
 
     3.24   Company Stock Ownership.  Except as contemplated pursuant to the
terms of this Agreement and the transactions to be consummated hereby or by the
Option Agreement, neither Acquiror nor any of the Acquiror Subsidiaries own any
shares of Company Common Stock or rights to acquire or dispose of Company Common
Stock.
 
     3.25   Voting Requirements.  There is no vote of the holders of any class
or series of Acquiror's capital stock necessary to approve and adopt this
Agreement and the transactions contemplated hereby.
 
     3.26   Books and Records.  The books of account, stock records, minute
books and other records of Acquiror and the Acquiror Subsidiaries are complete
and correct, and Acquiror has devised and maintained a system of internal
accounting controls sufficient to provide the reasonable assurances enumerated
in Section 13(b)(2)(B) of the Exchange Act.
 
     3.27   Disclosure.  Neither (i) the representations or warranties by
Acquiror contained in this Agreement, or the statements contained in the
Acquiror Disclosure Schedule or any other document, certificate or other
instrument delivered to or to be delivered by or on behalf of Acquiror or
required to be filed by Acquiror or any Acquiror Subsidiary with any
Governmental Entity in connection with or pursuant to this Agreement and all
other documents contemplated hereby, nor (ii) the information supplied or to be
supplied by or on behalf of Acquiror or any Acquiror Subsidiary to any person
for inclusion in any document or application filed or to be filed with any
Governmental Entity in connection with the transactions contemplated by this
Agreement, the Option Agreement and all other documents contemplated hereby and
thereby, contains or will contain any untrue statement of a material fact or
omits or will omit to state any material fact necessary, in light of the
circumstances under which it was or will be made, in order to make the
statements herein or therein not misleading or
 
                                      A-25

to correct a prior statement. All documents required to be filed by Acquiror or
any Acquiror Subsidiary with any Governmental Entity in connection with this
Agreement and all other documents contemplated hereby or the transactions
contemplated hereunder will comply in all material respects with the provisions
of applicable Law.
 
                                   ARTICLE IV
 
                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY
 
     On or prior to the date hereof, the Company has delivered to Acquiror a
schedule (the "Company Disclosure Schedule") setting forth, among other things,
items the disclosure of which is necessary or appropriate either (i) in response
to an express disclosure requirement contained in a provision hereof or (ii) as
an exception to one or more representations or warranties contained in Article
IV or to one or more of its covenants contained in Article V; provided that the
mere inclusion of an item in the Company Disclosure Schedule as an exception to
a representation or warranty shall not be deemed an admission by the Company
that such item represents a material exception or fact, event or circumstance or
that such item is reasonably likely to result in a Material Adverse Effect on
the Company. The Company represents and warrants to Acquiror and Merger Sub, as
of the date of this Agreement that, except as set forth in the Company
Disclosure Schedule, which shall identify exceptions by specific Section
references:
 
     4.1   Organization.  The Company and each of its subsidiaries (the "Company
Subsidiaries") has been duly organized and is validly existing and in good
standing (with respect to jurisdictions which recognize such concept) under the
laws of the jurisdiction of its organization, has all requisite power and
authority to own, operate and lease its properties and to carry on its business
as it is now being conducted, and is qualified or licensed to do business and is
in good standing (with respect to jurisdictions which recognize such concept) in
each jurisdiction in which the nature of the business conducted by it or the
ownership or leasing of its properties makes such qualification necessary, other
than where failure to be so qualified or licensed, individually or in the
aggregate, would not have a Material Adverse Effect on the Company. The term
"Material Adverse Effect on the Company" as used in this Agreement shall mean
any change or effect that, individually or when taken together with all such
other changes or effects, is or would reasonably be expected to be materially
adverse to the financial condition, results of operations, properties or
business of the Company and the Company Subsidiaries taken as a whole; provided,
however, that Material Adverse Effect on the Company shall not be deemed to
include the impact of (i) changes in general economic conditions or conditions
applicable to the assisted living industry generally, (ii) changes or effects
which result from the execution and delivery of this Agreement or the
consummation of any transactions contemplated hereby other than changes or
effects which result from (A) a change in control or change of control or
similar event applicable to the Company or any Company Subsidiary or (B) the
failure to obtain one or more Third Party Consents (as defined below) which
failure individually or in the
 
                                      A-26
<PAGE>   191
 
aggregate would have a Material Adverse Effect on the Company, (iii) the matters
set forth in Section 4.1 of the Company Disclosure Schedule, and (iv) the
inability of the Company to obtain the consent to this Agreement of Catholic
Health Initiatives ("CHI") related to the joint venture agreements between the
Company and CHI to develop, own and/or operate assisted living residences in
Ohio, New Mexico and Colorado. True and complete copies of the Articles of
Incorporation and the Code of Regulations, together with all amendments thereto,
of the Company have heretofore been delivered to Acquiror, and such Articles of
Incorporation and Code of Regulations are in full force and effect. Section 4.1
of the Company Disclosure Schedule contains a complete and accurate list of all
of the Company Subsidiaries, a list of the jurisdictions where the Company and
each of the Company Subsidiaries is duly qualified or licensed to do business as
a foreign organization and Company's percentage ownership in each such Company
Subsidiary. Neither the Company nor any Company Subsidiary is in violation of
any provision of its articles or certificate of incorporation or bylaws (each as
may have been amended or restated) or other organizational documents, as the
case may be.
 
     4.2   Capitalization.  As of the date of this Agreement, the authorized
capital stock of the Company consists in its entirety of (i) 28,000,000 shares
of Company Common Stock, and (ii) 2,000,000 shares of preferred stock, without
par value, none of which were issued and outstanding as of the date of this
Agreement. As of October 16, 1998, (i) 6,837,400 shares of Company Common Stock
were issued and outstanding, (ii) no shares of Company Common Stock were held in
the treasury of the Company, and (iii) 550,000 shares of Company Common Stock
were reserved for future issuance pursuant to employee stock options granted
pursuant to the Company Option Plans (as defined in Section 5.7). Each of the
outstanding shares of capital stock of the Company were issued in compliance
with all applicable federal and state laws concerning the issuance of
securities. Except as set forth on Section 4.2 of the Company Disclosure
Schedule, all of the outstanding shares of capital stock of each of the Company
Subsidiaries is owned beneficially and of record by the Company or a Company
Subsidiary, free and clear of all Encumbrances. All of the outstanding shares of
capital stock of the Company and each of the Company Subsidiaries have been duly
authorized, validly issued and are fully paid and nonassessable and are not
subject to preemptive rights created by statute, their respective charter or
bylaws or any agreement to which any such entity is a party or by which any such
entity is bound. The Company has heretofore delivered to Acquiror, correct and
complete copies of the Company's Stock Option Plans, in each case as currently
in effect. Except as set forth in this Section 4.2 or in Section 4.2 of the
Company Disclosure Schedule, there are no options, warrants, puts, calls or
other rights (including registration rights), agreements, arrangements or
commitments of any character to which the Company or any Company Subsidiary is a
party or by which any of them is bound relating to the issued or unissued
capital stock, or other interest in, of the Company or any Company Subsidiary or
obligating the Company or any Company Subsidiary to grant, issue, deliver or
sell, or cause to be granted, issued, delivered or sold, any shares of capital
stock of, or other equity interests in, the Company or any Company Subsidiary,
by sale, lease, license or otherwise. All

<PAGE>   192
 
shares of Company Common Stock subject to issuance as aforesaid, upon issuance
on the terms and conditions specified in the instruments pursuant to which they
are issuable, will be duly authorized, validly issued, fully paid and
nonassessable and will not have been issued in violation of or subject to any
preemptive rights created by statute, the articles of incorporation or bylaws of
the Company or any agreement to which the Company is a party or to which the
Company is bound. Except as set forth in this Section 4.2, in Section 4.2 of the
Company Disclosure Schedule or in the Company Current Reports (as defined in
Section 4.9), there are no outstanding contractual obligations of the Company or
any Company Subsidiary to (x) repurchase, redeem or otherwise acquire any shares
of Company Common Stock or any capital stock, or other interests in, of any
Company Subsidiary or (y) except for guarantees of obligations of, or loans to
or capital contribution commitments, the Company Subsidiaries entered into in
the ordinary course of business, provide funds to, make any investment in (in
the form of a loan, capital contribution or otherwise) or provide any guarantee
with respect to the obligations of, any Company Subsidiary or any other person.
There are no agreements, arrangements or commitments of any character
(contingent or otherwise) pursuant to which any person is or may be entitled to
receive any of the revenues or earnings, or any payment based thereon or
calculated in accordance therewith, of the Company or any Company Subsidiary.
Each outstanding share of capital stock, or other interest in, of each Company
Subsidiary is duly authorized, validly issued, fully paid and nonassessable and,
except as set forth in Section 4.2 of the Company Disclosure Schedule, each such
share owned by the Company or another Company Subsidiary is owned free and clear
of all Encumbrances. Except for the capital stock of the Company Subsidiaries
and except for the ownership interests set forth in Section 4.2 of the Company
Disclosure Schedule, the Company does not own, directly or indirectly, any
capital stock or other ownership interest in, or any interest convertible into
or exchangeable or exercisable for capital stock of or other ownership interest
in, any person. The Company is not aware of any voting trust, stockholder
agreement or other similar arrangement relating to any shares of Company Common
Stock.
 
     4.3   Options or Other Rights.  Except as disclosed in Section 4.3 of the
Company Disclosure Schedule or in the Company SEC Filings (as defined in Section
4.10), there is no outstanding right, subscription, warrant, call, unsatisfied
preemptive right, option or other agreement or arrangement of any kind to
purchase or otherwise to receive from the Company or any Company Subsidiary any
of the outstanding, authorized but unissued, unauthorized or treasury shares of
the capital stock or any other security of the Company or any Company Subsidiary
and there is no outstanding security of any kind convertible into or
exchangeable for such capital stock. Except as set forth in Section 4.3 of the
Company Disclosure Schedule or the Company SEC Filings, there are no agreements
or understandings among the Company or any Company Subsidiary on the one hand
and any other person on the other hand concerning the registration of any
security of the Company or a Company Subsidiary under the Securities Act. All
such registration rights agreements will be null and void and of no further
force and effect upon completion of the Merger. Except as set forth in Section
4.3 of the Company Disclosure Schedule, no options granted under the Company
Option Plans have
 
                                      A-28
<PAGE>   193
 
provisions which accelerate the vesting or right to exercise such options upon
the occurrence of certain events, including, but not limited to, the
consummation of the Merger.
 
     4.4   Authority Relative to this Agreement.  The Company has all requisite
corporate power and authority to execute and deliver this Agreement and the
Option Agreement, to perform its obligations hereunder and thereunder and to
consummate the transactions contemplated on its part hereby and thereby to be
consummated by the Company. The execution and delivery of this Agreement and the
Option Agreement by the Company and the consummation of the transactions
contemplated on its part hereby and thereby have been duly authorized by all
necessary corporate action, and, other than the approval of the Company's
stockholders as provided in Section 5.1(a) hereof, no other corporate
proceedings on the part of the Company are necessary to authorize the execution
and delivery of this Agreement and the Option Agreement by the Company or the
consummation of the transactions contemplated on its part hereby and thereby.
This Agreement and the Option Agreement have been duly executed and delivered by
the Company and, assuming the due authorization, execution and delivery of this
Agreement by Acquiror and Merger Sub, constitute the legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms, except to the extent that such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization or other laws
affecting the enforcement of creditors' rights generally or by general equity
principles.
 
     4.5   No Violation.  Other than as listed on Section 4.5 to the Company
Disclosure Schedule, the execution and delivery of this Agreement and of the
Option Agreement by the Company do not, the performance by the Company of its
obligations hereunder and thereunder will not, and the consummation by the
Company of the transactions contemplated to be performed by it hereby and
thereby will not (i) violate or conflict with any provision of any Law in effect
on the date of this Agreement and applicable to the Company or any Company
Subsidiary or by which any of their respective properties or assets is bound or
subject, (ii) require the Company or any Company Subsidiary to obtain any
consent, waiver, approval, license or authorization or permit of, or make any

compliance with the provisions of the Exchange Act, the Securities Act, the
OGCL, the Bylaws of the Nasdaq or the "takeover" or "blue sky" laws of various
states, (c) filing and recordation of appropriate merger documents as required
by the OGCL and (d) any other filings and approvals expressly contemplated by
this Agreement), (iii) require the consent, waiver, approval, license or
authorization of any person (other than Governmental Entities), (iv) violate,
conflict with or result in a breach of or the acceleration of any obligation
under, or constitute a default (or an event which with notice or the lapse of
time or both would become a default) under, or give to others any rights of, or
result in any, termination, amendment, acceleration or cancellation of, or loss
of any benefit or creation of a right of
 
                                      A-29
<PAGE>   194
 
first refusal, or require any payment under, or result in the creation of a lien
or other encumbrance on any of the properties or assets of the Company or any
Company Subsidiary pursuant to or under any provision of any indenture,
mortgage, note, bond, lien, lease, license, agreement, contract, order,
judgment, ordinance, Company Permit (as defined below) or other instrument or
obligation to which the Company or Company Subsidiary is a party or by which the
Company or any Company Subsidiary or any of their respective properties is bound
or subject to, or (v) conflict with or violate the Articles of Incorporation or
the Code of Regulations, or the equivalent organizational documents, in each

except for any such conflicts, consents, waivers, approvals, licenses, filings
or violations described in clause (i) or breaches, defaults, events, rights of
termination, amendment, acceleration or cancellation, payment obligations or
liens or encumbrances described in clause (iv) that would not have a Material
Adverse Effect on the Company and except for such consents, waivers, approvals,
licenses or authorizations described in clauses (ii) or (iii) that individually
or in the aggregate would not be material to the Company or to the Acquiror, and
except where the failure to obtain such consents, approvals, authorizations or
permits, or to make such filings or notifications would not, either individually
or in the aggregate, prevent the Company from performing any of its obligations
under this Agreement or the Option Agreement and would not have a Material
Adverse Effect on Company. Neither the Company nor any of its affiliates or
associates (as each such term is defined in Section 203 of the Delaware General
Corporation Law ("DGCL") is, prior to the date hereof, an "interested
stockholder" (as such term is defined in Section 203 of the DGCL) of Acquiror.
There are no reasonable grounds to believe that the Company or the Surviving
Corporation would be rendered insolvent by the Merger or the conversion of
Company Shares in the Merger within the meaning of Section 1701.78 of the OGCL.

where the failure to hold such Company Permits or to so comply or perform,
individually or in the aggregate, would not have a Material Adverse Effect on
the Company. No Company Permits will in any way be affected by, or terminate or
lapse by reason of, the transactions contemplated by this Agreement.

Medicare, Medicaid, CHAMPUS, state approved Medicaid waiver programs or any
other third-party reimbursement program has any claims for disallowance of costs
against any of them which could result in offsets against future reimbursement
or recovery of prior payments, which offsets or recoveries, individually or in
the aggregate, would have a Material Adverse Effect on Company.
 
     (e) The Company and the Company Subsidiaries have filed all forms, reports,
statements, and other documents required to be filed with any Governments
Entities, including, without limitation, state insurance and state and federal
health regulatory authorities and reimbursement programs, except where the

Section 4.6(e) would not have a Material Adverse Effect on the Company.

Subsidiary, nor the officers, directors, employees or agents of any of the
Company or any Company Subsidiary, have engaged in any activities which are

would not have a Material Adverse Effect on Company. Except as set forth in the
Section 4.8(b) of the Company Disclosure Schedule, (i) no notice of any offsets
against future reimbursement has been received by the Company or any Company
Subsidiary, nor to the knowledge of Company, is there any reasonable basis

the aggregate, reasonably be expected to result in a Material Adverse Effect on
the Company, (ii) there are no pending appeals, adjustments, challenges, audits,
litigation, notices of intent to reopen or open completed payments with respect

of business which could not, individually or in the aggregate, reasonably be
expected to result in a Material Adverse Effect on the Company, and (iii)
neither the Company nor any Company Subsidiary has received notice of pending,
threatened or possible decertification or other loss of participation in any of
the Governmental Programs which remains in effect as of the date hereof. Section
4.8(b) of the Company Disclosure Schedule lists any material contracts between
the Company or any Company Subsidiary and third party payors, copies of which
have been made available to the Company. The Company and each of the Company
Subsidiaries, as applicable, are in compliance in all material respects with all

4.9 of the Company Disclosure Schedule, there is no claim, litigation, suit,
arbitration, mediation, action, proceeding, unfair labor practice complaint or
grievance pending or, to the Company's knowledge, investigation of any kind, at
law or in equity (including actions or proceedings seeking injunctive relief),
pending or, to the Company's knowledge, threatened in writing against the
Company or any Company Subsidiary or with respect to any property or asset of
any of them, except for claims, litigations, suits, arbitrations, mediations,
actions, proceedings, complaints, grievances or investigations which,
individually or in the aggregate, (a) would not have a Material Adverse Effect
on the Company, (b) would not impair in any material respect the ability of the
Company or any Company Subsidiary to perform its obligations under this
Agreement or any other document contemplated hereby or thereby or (c) would not
prevent the consummation by the Company or any Company Subsidiary of any of the
transactions contemplated by this Agreement or any other document contemplated
hereby or thereby. Neither the Company nor any Company Subsidiary nor any
property or asset of any of them is subject to any continuing order, judgment,
settlement agreement, injunction, consent decree or other similar written
agreement with or, to the Company's knowledge, continuing investigation by, any
Governmental Entity, or any judgment, order, writ, injunction, consent decree or
award of any Governmental Entity or arbitrator, including, without limitation,
cease-and-desist or other orders, except for such matters which (a) would not
reasonably be expected to have a Material Adverse Effect on the Company, (b)
would not impair in any material respect the ability of the Company or any
Company Subsidiary to perform its obligations under this Agreement or any other
document contemplated hereby or thereby or (c) would not prevent the
consummation by the Company or any Company Subsidiary of any of the transactions
contemplated by this Agreement or any other document contemplated hereby or
thereby.
 
     4.10   Financial Statements and Reports.  The Company has made available to
Acquiror true and complete copies of (a) its Annual Report on Form 10-K for the
year ended December 31, 1997 (the "Company 10-K"), as filed with the Commission,
(b) its proxy statement relating to the annual meeting of its shareholders held
on May 12, 1998, (c) all registration statements filed by the Company and
declared effective under the Securities Act (other than registration statements
on Form S-8) and (d) all other reports, statements and registration statements
(including Quarterly Reports on Form 10-Q and Current Reports on Form 8-K but
excluding preliminary material and reports pursuant to Sections 13(d) or 13(g)
of the Exchange Act) filed by it with the Commission other than registration
statements on Form S-8. The reports, statements and registration statements
referred to in the immediately preceding sentence (including, without
limitation, any financial statements or schedules or other information included
or incorporated by reference therein) are referred to in this Agreement as the
"Company SEC Filings." As of the respective times such documents were filed or,
as applicable, were effective, the Company SEC Filings complied as to form in
all material respects with the requirements of the Securities Act or the
Exchange Act, as the case may be, and the rules and regulations promulgated
thereunder, and except to the extent that information contained in any Company
SEC Filings has been revised or superseded
 
                                      A-34

by a later Company SEC Filing filed and publicly available prior to the date of
this Agreement, did not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading. The financial statements of the Company included in the
Company SEC Filings complied as of their respective dates of filing with the
Commission as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the Commission with
respect thereto, were prepared in accordance with generally accepted accounting
principles (as in effect from time to time) applied on a consistent basis during
the periods involved (except as may be indicated therein or in the notes thereto
or, in the case of the unaudited interim financial statements, as permitted by
Form 10-Q of the Commission) and present fairly the consolidated financial
position, consolidated results of operations and consolidated cash flows of the
Company and the Company Subsidiaries as of the dates and for the periods
indicated, except (i) in the case of unaudited interim consolidated financial
statements, to normal recurring year-end audit adjustments and any other
adjustments described therein and (ii) any pro forma financial information
contained therein is not necessarily indicative of the consolidated financial
position of the Company and the Company Subsidiaries as of the respective dates
thereof and the consolidated results of operations and cash flows for the
periods indicated. No Company Subsidiary is required to file any form, report or
other document with the Commission. Except as set forth in the Company Current
Reports, and except for liabilities and obligations incurred in the ordinary
course of business consistent with past practice, since the date of the most
recent consolidated balance sheet included in the Company Current Reports,
neither the Company nor any Company Subsidiary has any liabilities or
obligations of any nature (whether accrued, absolute, contingent or otherwise)
required by generally accepted accounting principles to be recognized or
disclosed on a consolidated balance sheet of the Company and the Company
Subsidiaries or in the notes thereto which could reasonably be expected to have
a Material Adverse Effect on the Company. The pro forma financial information
(and related notes thereto) included in the Company SEC Filings present fairly
the information shown therein and were prepared, as of the respective dates of
filing of the Company SEC Filings with the Commission, in accordance with the
Commission's rules and guidelines with respect to pro forma financial
statements. The necessary pro forma adjustments have been properly applied to
the historical amounts in the compilation of such pro forma financial
information, the assumptions used in the preparation thereof are reasonable and
the adjustments used therein are appropriate to give effect to the transactions
and circumstances referred to therein.
 
     4.11   Absence of Certain Changes or Events.  Other than as disclosed in
the Company Current Reports or in Section 4.11 of the Company Disclosure
Schedule, since June 30, 1998 and through the date of this Agreement, the

Adverse Effect on the Company; (ii) any material indebtedness incurred by the
Company or any Company Subsidiary for borrowed money, except under credit
facilities disclosed in the Company Current Reports, if any; (iii) any

Company Subsidiaries; (iv) any damage, destruction or loss, whether covered by

consultant (other than as provided in employment agreements, consulting
agreements and welfare and benefit plans set forth on the Company Disclosure
Schedule, and except for increases consistent with past practice); (ix) any
material revaluation by the Company or any Company Subsidiary of any asset

indebtedness of any person or entity, other than in the ordinary course
consistent with past practice; (xii) any split, combination or reclassification

of, in lieu of or in substitution for shares of such capital stock; (xiii) any
receipt by the Company or any Company Subsidiary of written or oral notice that
any material contract, agreement or arrangement to which it is a party has been
or will be canceled; (xiv) any issuance by the Company or any Company Subsidiary
of any share of stock, bond, note, option, warrant or other corporate security;

     4.12   Employee Benefit Plans and Employment Matters.
 
     (a) Section 4.12(a) of the Company Disclosure Schedule lists all employee
benefit plans, collective bargaining agreements, labor contracts, and employment
agreements not otherwise disclosed in the Company Current Reports in which the
Company or any Company Subsidiary participates, or by which any of them are
bound, including, without limitation, (i) any profit sharing, deferred
compensation, bonus, stock option, stock purchase, pension, welfare, and
incentive plan or agreement; (ii) any plan providing for "fringe benefits" to
their employees, including, but not limited to, vacation, sick leave, medical,
hospitalization and life insurance; (iii) any written employment agreement and
any other employment agreement not terminable at will; and (iv) any other
"employee benefit plan" (within the meaning of Section 3(3) of ERISA). The
Company and the Company Subsidiaries are in compliance in all material respects
with the requirements prescribed by all Laws currently in effect applicable to
employee benefit plans and to any employment agreements, including, but not
limited to, ERISA and the Code. The Company and the Company Subsidiaries have
each performed all of its obligations under all such employee benefit plans and
employment agreements in all material respects. There is no pending or, to the
knowledge of the Company, threatened legal action, proceeding or investigation
against or involving any Company or Company Subsidiary employee benefit plan
which could result in a material amount of liability to such employee benefit
plan or to the Company, other than routine claims for benefits involving less
than $25,000 for each such routine claim and $100,000 for all such routine
claims in the aggregate.
 
     (b) Neither the Company nor the Company Subsidiaries sponsor or participate
in, and have not sponsored or participated in, any employee pension benefit plan
to which Section 4021 of ERISA applies that would create a material amount of
liability to the Company under Title IV of ERISA.
 
     (c) Neither the Company nor the Company Subsidiaries sponsor or participate
in, and have not sponsored or participated in, any employee pension benefit plan
that is a "multiemployer plan" (within the meaning of Section 3(37) of ERISA).
 
     (d) All group health plans of the Company and the Company Subsidiaries have
been operated in compliance with the group health plan continuation coverage
requirements of Section 4980B of the Code in all material respects, to the
extent such requirements are applicable.
 
     (e) There have been no acts or omissions by the Company or any Company
Subsidiary or by any fiduciary, disqualified person or party in interest with
respect to an employee benefit plan of the Company or any Company Subsidiaries
that have given rise to or could reasonably be expected to give rise to a
material amount of fines, penalties, taxes, or related charges under Sections
502(c), 502(i) or 4071 of ERISA or under Chapter 43 of the Code.
 
     (f) No "reportable event," as defined in ERISA Section 4043, other than
those events with respect to which the Pension Benefit Guaranty Corporation has
waived the
 
                                      A-37
<PAGE>   202
 
notice requirement, has occurred with respect to any of the employee benefit
plans of the Company.
 
     (g) Section 4.12(g) of the Company Disclosure Schedule sets forth the name
of each director, officer or employee of the Company or any Company Subsidiary
entitled to receive any benefit or payment under any existing employment
agreement, severance plan or other benefit plan solely as a result of the
consummation of any transaction contemplated by this Agreement, and with respect
to each such person, the identity of the specific agreement relating to such
person, which agreement the Company has previously provided to Acquiror.
 
     (h) The Company has furnished Acquiror with true and correct copies of all
plan documents and employment agreements referred to on the Company Disclosure
Schedule, including all amendments thereto, and all related summary plan
descriptions to the extent that one is required by Law.
 
     (i) For purposes of this Section 4.12, any reference to the "Company" shall
be deemed to include a reference to any entity that is aggregated with the
Company under the provisions of Section 414 of the Code, to the extent that
those aggregation rules apply to any representation made herein.
 
     4.13   Labor Matters.  Neither the Company nor any Company Subsidiary is a
party to any collective bargaining agreement with respect to any of their
employees. None of the employees of the Company or any Company Subsidiary is
represented by any labor union. To the knowledge of the Company, there is no
activity involving any employees of the Company or the Company Subsidiaries
seeking to certify a collective bargaining unit or engaging in any similar
organizational activity.
 
     4.14   Insurance.  The Company and the Company Subsidiaries maintain
insurance against such risks and in such amounts as the Company reasonably
believes are necessary to conduct its business. The Company and the Company
Subsidiaries are not in default with respect to any provisions or requirements
of any such policy, nor have any of them failed to give notice or present any
claim thereunder in a due and timely fashion, except for defaults or failures
which, individually or in the aggregate, would not have a Material Adverse
Effect on Company. Neither the Company nor any Company Subsidiary has received
any notice of cancellation or termination in respect of any of its insurance
policies.
 
     4.15   Environmental Matters.  Except as disclosed on Section 4.15 of the
Company Disclosure Schedule:
 
         (a) The Company and the Company Subsidiaries have complied and are in
     compliance with, and the real property owned, operated, leased or used by
     the Company or the Company Subsidiaries as of June 30, 1998, any additional
     real property owned, operated, leased or used since that date, and, for
     purposes of this Section 4.15, any real property formerly owned or operated
     by the Company or any Company Subsidiary (collectively, the "Company Real
     Property") and all improvements thereon are in compliance with, all
     Environmental Laws, except for such non-
 
                                      A-38
<PAGE>   203
 
     compliance as would not have a Material Adverse Effect on the Company and
     would not be considered "material" under the federal securities laws.
 
         (b) Neither the Company nor any Company Subsidiary has any liability
     under any Environmental Law, nor is the Company or any Company Subsidiary
     responsible by contract, by operation of law, otherwise for any liability
     of any other person under Environmental Law, which either individually or
     in the aggregate would have a Material Adverse Effect on the Company or
     would be considered "material" under the federal securities laws. Except
     for matters which would not have a Material Adverse Effect on the Company
     and would not be considered "material" under the federal securities laws,
     there are no pending or threatened actions, suits, orders, claims, legal
     proceedings or other proceedings based on, and neither the Company nor any
     Company Subsidiary, nor any officer, director or stockholder thereof has
     directly or indirectly received any formal or informal notice of any
     complaint, order, directive, citation, notice of responsibility, notice of
     potential responsibility, or information request from any Governmental
     Entity or any other person or entity or knows or suspects any fact(s) which
     might reasonably form the basis for any such actions or notices arising out
     of or attributable to: (i) the current or past presence, Release, or
     threatened Release of Hazardous Materials at or from any part of the
     Company Real Property; (ii) the off-site disposal or treatment of Hazardous
     Materials originating on or from the Company Real Property or the
     businesses or assets of the Company or any Company Subsidiary; or (iii) any
     violation of Environmental Laws at any part of the Company Real Property or
     arising from the Company's or any Company Subsidiary's activities (or the
     activities of the Company's or any Company Subsidiary's predecessors in
     title) involving Hazardous Materials.
 
         (c) Except as disclosed in Section 4.15(c) of the Company Disclosure
     Schedule, the Company and the Company Subsidiaries have been duly issued,
     and currently have and will maintain through the Closing Date, all permits,
     licenses, certificates and approvals required under any Environmental Law,
     each of which is valid and in full force and effect. Except in accordance
     with such permits, licenses, certificates and approvals, there has been no
     Release of material regulated by such permits, licenses, certificates or
     approvals at, on, under, or from the Company Real Property.
 
         (d) Neither the Company nor any Company Subsidiary has provided to any
     Governmental Entity, as required by Law, notice of any Release from any
     underground improvements, including but not limited to treatment or storage
     tanks, or underground piping associated with such tanks, used currently or
     in the past for the management of Hazardous Materials. No portion of the
     Company Real Property is or has been used as a dump or landfill or consists
     of or contains filled in land or wetlands.

         (e) No Encumbrance in favor of any person relating to or in connection
     with any Claim under any Environmental Law has been filed or has attached
     to the Company Real Property.
 
     4.16   Tax Matters.  Neither Company nor, to the knowledge of Company, any
of its affiliates has taken or agreed to take any action that would, nor does
Company have any knowledge of any fact or circumstance that is reasonably likely
to, prevent the Merger from qualifying as a reorganization under the provisions
of Section 368(a) of the Code. The Company has paid, or made provision in
accordance with generally accepted accounting principles on its balance sheet at
December 31, 1997 included in the Company 10-K, for all federal, state, local,
foreign or other governmental income, franchise, payroll, F.I.C.A.,
unemployment, withholding, real property, personal property, sales, payroll,
disability and all other taxes imposed on the Company or any Company Subsidiary
or with respect to any of their respective properties, or otherwise payable by
them, including interest and penalties, if any, in respect thereof
(collectively, "Company Taxes"), for the Company taxable period ended December
31, 1997 and all fiscal periods of the Company prior thereto, except such
nonpayment, or failure to make provision, which, individually or in the
aggregate, would not have a Material Adverse Effect on the Company and except as
set forth in Section 4.16 to the Company Disclosure Schedule. The Company Taxes
paid and/or incurred from December 31, 1997 until the Closing Date shall include
only Company Taxes incurred in the ordinary course of business. The Company and
each of the Company Subsidiaries have timely filed all returns, reports and
certifications related to Company Taxes which the Company and/or such Company
Subsidiary (as the case may be) are required to file ("Company Tax Returns"),
and have paid or provided for all the amounts shown to be due thereon, except
where such failure to make such timely filings, individually or in the
aggregate, would not have a Material Adverse Effect on the Company, and except
for the nonpayment of such amounts which, individually or in the aggregate,
would not have a Material Adverse Effect on the Company. Neither the Company nor
any Company Subsidiary (i) has filed or entered into, or is otherwise bound by,
any currently effective election, consent or extension agreement that extends
any applicable statute of limitations with respect to taxable periods of the
Company, (ii) is a party to any contractual obligation requiring the
indemnification or reimbursement of any person with respect to the payment of
any Company Taxes, other than among the Company and the Company Subsidiaries, or
(iii) has received any claim by an authority in a jurisdiction where neither the
Company nor any Company Subsidiary files Company Tax Returns that they are or
may be subject to Company Taxes by that jurisdiction, except for any such claims
as, individually or in the aggregate, would not have a Material Adverse Effect
on the Company. No action or proceeding is pending or, to the Company's
knowledge, threatened orally to any Company officer or in writing by any
governmental authority for any audit, examination, deficiency, assessment or
collection from the Company or any Company Subsidiary of any Company Taxes, no
unresolved claim for any deficiency, assessment or collection of any Company
Taxes has been asserted against the Company or any Company Subsidiary, and all
resolved assessments of Company Taxes have been paid or are reflected on the
Company balance sheet at December 31, 1997 included in the Company
 
                                      A-40
<PAGE>   205
 
10-K, except for any of the foregoing which, individually or in the aggregate,
would not have a Material Adverse Effect on the Company. The Company has not
filed a consent under Section 341(f) of the Code concerning collapsible
corporations. The Company does not have any liability for the taxes of any
person other than the Company Subsidiaries (i) under Treas. Reg. Section
1.1502-6 (or any similar provision of state, local or foreign law), (ii) as a
transferee or successor, (iii) by contract, or (iv) otherwise.
 
     4.17   Intellectual Property.  Except as disclosed in Section 4.17 of the
Company Disclosure Schedule, the Company and the Company Subsidiaries own, or
are licensed or otherwise possess or have all necessary rights to use all
Intellectual Property which is used in the conduct of their respective
businesses (collectively, "Company Intellectual Property Rights"). To the
knowledge of the Company, neither the Company nor any Company Subsidiary is
infringing or otherwise violating the intellectual property rights of any person
which infringement or violation would subject the Company or any Company
Subsidiary to liabilities which, individually or in the aggregate, would have a
Material Adverse Effect on the Company or which would prevent the Company or any
Company Subsidiary from conducting their respective businesses substantially in
the manner in which they are now being conducted. No claim has been made or, to
the Company's knowledge, threatened against the Company or any Company
Subsidiary alleging any such violation. To the knowledge of the Company, there
is no unauthorized use, disclosure, infringement or misappropriation of any
Company Intellectual Property Rights or any Intellectual Property right of any
third party to the extent licensed by or through Company, by any third party,
including any employee or former employee of the Company, that could reasonably
be expected to have a Material Adverse Effect on the Company. The Company is
not, nor will it be as a result of the execution and delivery of this Agreement
or the performance of it obligations under this Agreement, in breach of any
license, sublicense or other agreement relating to the Company Intellectual
Property Rights or Third Party Intellectual Property Rights. The Company has not
advised any third party that such third party may be infringing any Company
Intellectual Property Rights or breaching any license or agreement involving
Company Intellectual Property Rights that could reasonably be expected to have a
Material Adverse Effect on Company.
 
     4.18   Related Party Transactions.  Except as disclosed in the Company SEC
Filings or in Section 4.18 of the Company Disclosure Schedule, there have been
no material transactions between the Company or any Company Subsidiary on the
one hand, and any (i) officer or director of the Company or any Company
Subsidiary, (ii) record or beneficial owner of five percent or more of the
voting securities of the Company or (iii) affiliate (as such term is defined in
Regulation 12b-2 promulgated under the Exchange Act) of any such officer,
director or beneficial owner, on the other hand, other than payment of
compensation for services rendered to the Company or the Company Subsidiaries or
the grant of stock options to purchase shares of Company Common Stock.

Company Current Reports, neither the Company nor any of the Company Subsidiaries
has incurred any liabilities of any kind whatsoever, whether accrued,
contingent, absolute, determined, determinable or otherwise, that, individually
or in the aggregate, would have a Material Adverse Effect on the Company other
than (i) liabilities incurred in the ordinary course of business consistent with
past practice since June 30, 1998 and identified in Schedule 4.19 of the Company
Disclosure Schedule or the Company SEC Filings, (ii) liabilities that have been
repaid, discharged or otherwise extinguished and (iii) liabilities under or

lapse of time or both would constitute a default or violation) of any term,
condition or provision of (i) its certificate or articles of incorporation or
bylaws or other organizational documents, (ii) any Laws applicable to the
Company or any Company Subsidiary or by which any of their respective properties
is bound or affected, or (iii) any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which the Company or any Company Subsidiary is a party or by which the
Company or any Company Subsidiary or any of their respective properties or
assets is bound or affected, except in the case of clauses (ii) and (iii) above
for defaults or violations which would not have a Material Adverse Effect on the
Company.
 
     4.21   Title to Properties; Encumbrances.  Section 4.21 of the Company
Disclosure Schedule sets forth all real property owned or leased by the Company
and the Company Subsidiaries (the "Company Real Property"), indicating which

personal and mixed, tangible and intangible), including, without limitation, all
Company Real Property and all other properties and assets reflected in the
consolidated balance sheet of the Company and the Company Subsidiaries at June
30, 1998 included in the Company Form 10-Q for the quarter ended June 30, 1998
(except for properties and assets disposed of in the ordinary course of business
and consistent with past practice since June 30, 1998) and (ii) none of such
properties or assets are subject to any liability, obligation, claim, lien,
mortgage, pledge, security interest, conditional sale agreement, charge or
encumbrance of any kind (whether absolute, accrued, contingent or otherwise),
except for liens securing repayment of indebtedness incurred in the ordinary
course consistent with past practice subsequent to June 30, 1998 and liens for
taxes not yet due and payable, unrecorded and undelivered mortgages between a
Company Subsidiary and a joint venture entity in which the Company is a limited
partner or a managing member (as identified in Section 4.21 of the Company
Disclosure Schedule) and easements and restrictions of record, if any, which are
not substantial in amount, do not materially detract from the value of the
property or assets subject thereto and do not impair the operations of the
Company and the Company Subsidiaries. Each of the leases is in full force and
effect
 
                                      A-42

and there is no default by landlord or tenant existing thereunder (and no event
has occurred which, with or without notice or the passage of time or both, would
constitute a default under such lease) which would have a Material Adverse
Effect on the Company. Except as set forth in Section 4.21 of the Company
Disclosure Schedule, the Company and the Company Subsidiaries have obtained
owner's title insurance on all of the Company Real Property owned by the Company
or any Company Subsidiary, in each case insuring good and marketable fee simple
title to such Company Real Property, in an amount at least equal to the
aggregate value of such Company Real Property together with all improvements
thereon. Except as set forth in Section 4.21 of the Company Disclosure Schedule,
there are no mechanics' or materialmen's liens or liens of a similar nature in
existence with respect to any on-going construction activities involving any of
the Company Real Property that, with respect to each such construction activity,
exceeds $50,000 individually, or $200,000 in the aggregate. Except as would not
cause a Material Adverse Effect on the Company, all of the properties and assets
of the Company and the Company Subsidiaries are in good operating condition and
repair, and maintenance thereon has not been deferred beyond industry standards,
and are suitable for the purposes for which they are presently being used.
 
     4.22   Brokers.  Neither the Company nor any Company Subsidiary has paid or
is obligated to pay any brokerage, finders or other fee or commission to any
broker, finder, investment banker or other intermediary in connection with this
Agreement or the Option Agreement, except that Company has retained BT Alex.
Brown Incorporated ("BT Alex. Brown") as its financial advisor for the
transactions contemplated hereby, pursuant to an engagement letter a copy of
which (as executed by all the parties thereto) has been provided previously to
Acquiror.
 
     4.23   Opinion of Financial Advisor.  The Board of Directors of the Company
has received the opinion of BT Alex. Brown to the effect that, as of the date of
this Agreement, the Exchange Ratio is fair to the holders of Company Common
Stock, from a financial point of view, a written copy of which (as executed)
will be provided to Acquiror promptly after receipt thereof by the Company.
 
     4.24   Acquiror Stock Ownership.  Except as contemplated pursuant to the
terms of this Agreement and the transactions to be consummated hereby or by the
Option Agreement, neither the Company nor any of the Company Subsidiaries own
any shares of Acquiror Common Stock or rights to acquire or dispose of Acquiror
Common Stock.
 
     4.25   Voting Requirements.  The affirmative vote of the holders of
two-thirds of the outstanding shares of Company Common Stock at the Company
Stockholders' Meeting (as defined in Section 5.1(a)) to adopt this Agreement is

stock necessary to approve and adopt this Agreement and the transactions
contemplated hereby under the OGCL and otherwise.
 
     4.26   State Takeover Statutes.  The Ohio Control Share Acquisition Statute
does not apply to the execution, delivery and performance of this Agreement or
the Option Agreement or the transactions contemplated hereby or thereby. To the
knowledge of Company, no Laws that would reasonably be considered a state
takeover or anti-takeover
 
                                      A-43

law are applicable to the execution, delivery and performance of this Agreement
or the Option Agreement or the transactions contemplated hereby or thereby.
 
     4.27   Requested Information; Material Contracts.
 
     (a) The Company has provided all documents, materials, schedules and other
information in response to the requests for such documents, materials, schedules
and other information from Acquiror identified in Section 4.27(a) of the Company
Disclosure Schedule.
 
     (b) Each existing contract, agreement, arrangement or understanding of the
Company or any of the Company Subsidiaries, including contracts, agreements,
arrangements or understandings (whether oral or written) between the Company or
any of the Company Subsidiaries, on the one hand, and one or more persons who
are affiliates of each other, on the other hand, involving, or reasonably
expected to involve, aggregate payments or commitments of more than $250,000
during the 12-month period ended June 30, 1998 or during the remaining term
thereof (the "Company Material Contracts"), is in full force and effect and
constitutes a legal, valid and binding obligation of, and is legally enforceable
against, the respective parties thereto. All necessary approvals of any
Governmental Entity with respect thereto have been obtained (except where the
failure so to obtain any such approval would not have a Material Adverse Effect
on the Company), all necessary filings or registrations therefor have been made,
and there are no outstanding disputes thereunder and, to the knowledge of the
Company or any of the Company Subsidiaries, no threatened cancellation or
termination thereof. The Company and each of the Company Subsidiaries have
performed all material obligations thereunder required to be performed by any of
them to date. No party is in default in any material respect under any of the
Company Material Contracts, and there has not occurred any event which (whether
with or without notice, lapse of time or the happening or occurrence of any
other event) would constitute such a default. There has been no written or oral
modification or amendment to any Company Material Contract and there are no
reasonably expected changes to any Company Material Contract.
 
     4.28   Receivables.  To the knowledge of the Company, all receivables shown

Company Current Reports, or thereafter acquired by the Company, are collectible,
and all appropriate reserves or allowances relating to such receivables have
been properly accrued.
 
     4.29   Books and Records.  The books of account, stock records, minute
books and other records of the Company and the Company Subsidiaries are complete
and correct, and the Company has devised and maintained a system of internal
accounting controls sufficient to provide the reasonable assurances enumerated
in Section 13(b)(2)(B) of the Exchange Act.
 
     4.30   No Excess Parachute Payments.  Except as set forth in Section 4.30
of the Company Disclosure Schedule, no amount that could be received (whether in
cash or
 
                                      A-44
<PAGE>   209
 
property or the vesting of property) as a result of any of the transactions
contemplated by this Agreement by any employee, officer or director of the
Company or any of its affiliates who is a "disqualified individual" (as such
term is defined in Section 280G(c) of the Code) under any employment, severance
or termination agreement, other compensation arrangement or Company Option Plan
or Other Company arrangement currently in effect would be an "excess parachute
payment" (as such term is defined in Section 280G(b)(1) of the Code).
 
     4.31   Change of Control Provisions.  Except to the extent described in
Section 4.31 of the Company Disclosure Schedule, neither the consummation of the
Merger nor the execution, delivery or performance of this Agreement, the Option
Agreement, or the other transactions contemplated hereby or thereby, will
trigger or constitute a "change in control" or "change of control" or similar
event under any provision of any contract or agreement to which the Company or
any Company Subsidiary is a party.
 
     4.32   Franchise Activities.  To the knowledge or the Company, neither the
Company nor any Company Subsidiary has violated any applicable federal or state
Laws regulating franchises or business opportunities, including registration and
disclosure requirements under such Laws, the violation of which could result in
a Material Adverse Effect on the Company. Neither the Company nor any Company
Subsidiary has violated or is currently violating any franchise agreement or
other agreement relating to its franchise activities. All franchise offering
circulars used by the Company or any Company Subsidiary comply as to form in all
material respects with all applicable federal and state Laws, are deemed an
acceptable form of disclosure document in all states which have in effect
franchise registration and disclosure Laws or other applicable business
opportunity Laws, are accurate and complete in all material respects and do not
contain any untrue statement of a material fact or omit to state any material
fact necessary, in light of the circumstances under which it was made, in order
to make the statements therein not misleading. Neither the Company nor any
Company Subsidiary is subject to a currently effective injunctive or restrictive
order relating to franchises or business opportunities under a federal or state
franchise, business opportunity, antitrust, trade regulation or trade practice
Law resulting from a concluded or pending action or proceeding brought by a
Governmental Entity.
 
     4.33   Disclosure.  Neither (i) the representations or warranties by the
Company contained in this Agreement or the Option Agreement, or the statements
contained in the Company Disclosure Schedule or any other document, certificate

Company or required to be filed by the Company or any Company Subsidiary with

order to make the statements herein or therein not misleading or to correct a
prior statement. All documents required to be filed by the Company or any
Company Subsidiary with any Governmental Entity in connection with this
Agreement, the Option Agreement and all other documents contemplated hereby or

     (a) The Company hereby agrees that this Agreement shall be submitted to its
shareholders for approval and adoption at a meeting duly called and held

to the extent necessary in accordance with applicable law and its charter and
bylaws, to convene the Company Shareholders' Meeting promptly to consider and

As soon as practicable (but in no case longer than 45 days) after the date of
this Agreement, Company and Acquiror shall jointly prepare and file with the
Commission, subject to the prior approval of the other party, which approval
shall not be unreasonably withheld, preliminary proxy materials relating to such

"Registration Statement") relating to the registration under the Securities Act
of the shares of Acquiror Common Stock issuable to the holders of the Company
Shares. Acquiror shall also promptly prepare and file with state securities
administrators, such registration statements or other documents as may be
required (other than qualification to do business in any jurisdiction in which
it is not now so qualified and other than general consent to service of process)
under applicable blue sky laws to qualify or register the shares of Acquiror
Common Stock issuable to the holders of the Company Shares (the "Blue Sky
Filings"). The Company, Merger Sub and Acquiror will use their respective best
efforts to cause the Registration Statement to be declared effective under the
Securities Act as soon as practicable. Promptly after the Registration Statement
has become effective and all applicable blue sky laws have been complied with,
the Company and Acquiror shall mail the proxy statement/prospectus included in
the Registration Statement to the Company's shareholders. Such proxy
statement/prospectus at the time it initially is mailed to the shareholders of

make the statements therein not misleading. The information supplied by the
Company for inclusion in the Proxy Statement to be sent to the shareholders of

Merger shall not, at the date the Proxy Statement (or any amendment thereof or
supplement thereto) is first mailed to shareholders or at the time of such
Meeting, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they are made,
not misleading. The information supplied by Acquiror for inclusion in the

declared effective, contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein not misleading.

Effective Time, any event relating to it or any of its affiliates, officers or
directors is discovered that is required to be set forth in an amendment to the
Registration Statement or Blue Sky Filings or a supplement to the Proxy
Statement, such party will promptly inform the other parties, and such amendment
or supplement will be promptly filed with the Commission and appropriate state
securities administrators and disseminated to the shareholders of the Company,
to the extent required by applicable federal and state securities laws, and (ii)
documents which either party files or is responsible for filing with the
Commission and any regulatory agency in connection with the Merger (including,
without limitation, the Proxy Statement) will comply as to form and content in

shareholders, (ii) approved the Merger and approved and adopted this Agreement
and (iii) resolved to and will recommend in the Proxy Statement adoption of this

unless following an announcement or receipt by the Company of a proposal for a
Third Party Transaction (as defined below) such Board of Directors (A) is
advised in writing by independent outside counsel to the Company that such
resolution and recommendation violate such fiduciary duties of directors as are
applicable under Ohio law because of such proposal for a Third Party Transaction
and (B) concludes based on such advice that such resolution and recommendation
violate such fiduciary duties as are applicable under Ohio law because of such
proposal for a Third Party Transaction.
 
     (e) The Company shall use its best efforts to cause to be delivered to
Acquiror a letter of Ernst & Young ("E&Y"), the Company's independent
accountants, dated a date within two (2) business days before the date on which
the Registration Statement shall become effective, addressed to Acquiror, of the

Acquiror Disclosure Schedule or otherwise consented to or approved in writing by
the Company, which consent shall not be unreasonably withheld or delayed, or
expressly permitted or contemplated by this Agreement or the Option Agreement:
 
         (a) Acquiror shall, and shall cause the Acquiror Subsidiaries to,
     conduct their respective businesses (to the extent commercially reasonable)
     only in the ordinary course and consistent in all material respects with
     past practice, and in compliance in all material respects with all
     applicable Laws and regulations, and shall use their respective best
     efforts to preserve substantially intact their respective business
     organizations and assets;
 
         (b) Acquiror shall not, and shall cause each Acquiror Subsidiary not
     to, intentionally take any action that (without regard to any action taken
     or agreed to be taken by the Company or any Company Subsidiary) would
     prevent the Merger from qualifying as a reorganization within the meaning
     of Sections 368(a)(1)(A)
 
                                      A-51
<PAGE>   216
 
     or 368(a)(2)(E) of the Code or that would result in the conditions set
     forth in clause (iii) of Sections 6.1 (h) and (i) not being true;
 
         (c) Acquiror shall not, and shall cause each Acquiror Subsidiary not
     to, take any action or fail to take any action which could reasonably be
     expected to have a Material Adverse Effect on Acquiror prior to or after
     the Effective Time, or that could reasonably be expected to adversely
     effect the ability of Acquiror prior to the Effective Time to obtain any
     Third Party Consents required to consummate the transactions contemplated
     by this Agreement.
 
         (d) Acquiror shall not enter into any transaction contemplating the
     acquisition of Acquiror (an "Acquisition Transaction") which would
     reasonably be expected to materially delay the timing of the Company
     Shareholders' Meeting or the Closing Date, unless Acquiror's Board of
     Directors (A) is advised in writing by outside counsel to the Acquiror that
     the failure to enter into such transaction would cause the members of the
     Board of Directors to breach such fiduciary duties as are applicable under
     Delaware law and (B) concludes based on such advice that the failure to
     enter into such transaction would cause the members of such Board of
     Directors to breach such fiduciary duties as are applicable under Delaware
     law; provided, however, that, so long as the Company is not in material
     breach of any provision of this Agreement, if Acquiror intends to enter
     into an Acquisition Transaction consistent with this subparagraph (d) that
     would cause Acquiror to merge into or consolidate with another Person or
     become a subsidiary of another Person in a transaction in which
     stockholders of Acquiror receive securities or other property from another
     Person (1) Acquiror agrees to use its best efforts to make adequate
     provision in such Acquisition Transaction for shareholders of the Company
     to be entitled to receive, in lieu of Acquiror Common Stock as provided in
     Article II, the same type of securities or other property from another
     Person that the stockholders of Acquiror would so receive from such other
     Person, giving effect to the Exchange Ratio but using as the trading period
     for calculation of the Average Trading Price of Acquiror Common Stock the
     ten (10) day trading period ending three trading days prior to the
     Acquiror's execution and delivery of the definitive agreement for such
     Acquisition Transaction and (2) if Acquiror executes and delivers a
     definitive agreement with respect to an Acquisition Transaction, then
     Acquiror agrees to waive as of the date of the execution and delivery of
     such definitive agreement Sections 6.3(b) and (c) and the corresponding
     provisions of Section 6.3(d) so long as (x) Sections 6.3(b) and (c) are
     satisfied as of the date of such execution and delivery of such definitive
     agreement, (y) as of such date, it may reasonably be expected that such
     conditions would continue to be satisfied as of the date the Closing
     hereunder would reasonably have been expected to occur absent any delay
     occasioned by such Acquisition Transaction and (z) the Company agrees to
     waive at the time of such waiver Sections 6.2(b) and (c) and the
     corresponding provisions of Section 6.2(d).
 
                                      A-52
<PAGE>   217
 
         (e) Acquiror shall not, and shall cause each Acquiror Subsidiary not
     to, authorize commit to, agree to, or enter into any agreement or
     understanding to do any of the things prohibited by clauses (a) through (d)
     of this Section 5.3.
 
     5.4   Access to Properties and Records.  To the extent permitted by
applicable Law and subject to the terms of the confidentiality agreements dated
October 6, 1998 and October 8, 1998, respectively, between the Company and
Acquiror (the "Confidentiality Agreements"), each party shall, and shall cause
its respective subsidiaries to, afford to the other party and their respective
accountants, counsel and representatives ("Respective Representatives"),
reasonable access during normal business hours upon reasonable prior notice
throughout the period prior to the Effective Time to all of their respective
properties (including, without limitation, access to books, contracts,
commitments, written records and the right to enter and inspect real property)
and shall make reasonably available during normal business hours upon reasonable
prior notice their respective officers and employees to answer fully and
promptly questions put to them thereby; provided, however, that no investigation
or review (including any investigation or review of real property) pursuant to
this Section 5.4 shall alter any representation or warranty of any party hereto
or the conditions to the obligations of the parties hereto or have any effect
for purposes of determining the accuracy of any representation or warranty given
by any party hereto to the other parties hereto. Each of the Company and
Acquiror will hold, and will cause its Respective Representatives to hold, any
nonpublic information in accordance with the terms of the Confidentiality
Agreements.
 
     5.5   No Solicitation of Transactions.
 
     (a) None of the Company or any Company Subsidiary shall, or shall authorize
or permit any of its officers, directors or employees or any investment banker,
financial advisor, attorney, accountant or other representative or agent
retained by the Company or any Company Subsidiary to, initiate or solicit or
encourage (including by way of furnishing non-public information), or take any
other action to facilitate, any inquiries or the making of any proposal that
constitutes, or may reasonably be expected to lead to, any Third Party
Transaction (as such term is defined below in this Section 5.5), or enter into
or maintain or continue discussions or negotiate with any person or entity in
furtherance of such inquiries or to obtain a Third Party Transaction; provided,
however, that, commencing 120 days after the date of this Agreement and
continuing until the Closing Date, the Company may, and may authorize and permit
its officers, directors, employees or agents to, furnish or cause to be
furnished confidential or other non-public information and may participate in
such discussions and negotiations if the Company's Board of Directors (A) is
advised in writing by independent outside counsel to the Company that the
failure to furnish such confidential or other non-public information or to
participate in such discussions and negotiations would cause the members of the
Board of Directors to breach such fiduciary duties as are applicable under Ohio
law and (B) concludes based on such advice that the failure to furnish such
confidential or other non-public information or to participate in such
discussions and negotiations would cause the members of such Board of Directors
to breach such fiduciary duties as are applicable under Ohio law; provided,
further, however, that at least 72 hours prior to furnishing any
 
                                      A-53
<PAGE>   218
 
such confidential or other non-public information, the Company shall furnish
copies of all such information to Acquiror, together with any inquiries,
proposals, bids, offers or other documentation received by the Company from the
party or parties to whom such confidential or other non-public information is to
be furnished by the Company and information as to the identity of such party or
parties. Except in circumstances in which the immediately preceding proviso
applies, in which event such proviso shall govern, the Company shall immediately
notify Acquiror orally and in writing of all relevant details relating to all
proposals which it or any Company Subsidiary or any such officer, director,
employee, investment banker, financial advisor, attorney, accountant or other
representative may receive relating to any of such matters and, if such inquiry
or proposal is in writing, the Company shall forthwith deliver to Acquiror a
copy of such inquiry or proposal.
 
     (b) For purposes of this Agreement, "Third Party Transaction" shall mean
any of the following other than transactions between Acquiror, Merger Sub and
the Company contemplated in this Agreement: (i) any merger, consolidation, share
exchange, business combination, recapitalization or other similar transaction
involving the Company or any of its subsidiaries; (ii) any sale, exchange,
transfer or other disposition of 20% or more of the assets of the Company and
its subsidiaries, taken as a whole, in a single transaction or series of
transactions; (iii) any sale of or tender offer or exchange offer for 20% or
more of the outstanding shares of capital stock of the Company or the filing of
a registration statement under the Securities Act in connection therewith; (iv)
any person acquiring 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 and the rules and regulations promulgated thereunder) having been
formed for the purpose of effecting a Third Party Transaction referred to in
Sections 5.5(b)(i), (ii) or (iii) which beneficially owns or has the right to
acquire beneficial ownership of, 20% or more of the then outstanding shares of
capital stock of the Company; or (v) any public announcement by such party of a
proposal, plan or intention to do any of the foregoing or any agreement to
engage in any of the foregoing with respect to the Company or any communication
to the Company of any proposal, plan or intention to do any of the foregoing.
 
     5.6   Compliance by Merger Sub; Conduct of Business by Merger
Sub.  Acquiror shall take all action necessary to cause Merger Sub to perform
its obligations hereunder (including, but not limited to, consummation of the
Merger) and to otherwise comply with the terms hereof. Merger Sub shall not
conduct any business between the date of this Agreement and the Closing Date,
other than to consummate the Merger and the transactions contemplated by this
Agreement.
 
     5.7   Treatment of Options.
 
     (a) The Company shall use its best efforts to deliver to Acquiror, on or
immediately prior to the Effective Time, either (1) new option agreements
evidencing the consent of each holder of a Company Stock Option to have such
Company Stock Option assumed by Acquiror and to become an option to acquire
Acquiror Common
 
                                      A-54
<PAGE>   219
 
Stock or (2) the opinion of Company's counsel called for by clause (B) of
Section 6.3(h). Each Company Stock Option issued pursuant to the Company's 1996
Incentive Stock Plan, as amended or issued other than pursuant to such plan as
set forth in the Company Disclosure Schedule (the "Company Option Plans"),
whether or not vested or exercisable, shall, subject to execution and delivery
of a new option agreement by the holder, be assumed by Acquiror and shall
constitute an option to acquire, on the same terms and conditions as were
applicable under such assumed Company Stock Option, a number of shares of
Acquiror Common Stock equal to the product of the Exchange Ratio and the number
of shares of Company Common Stock subject to such Company Stock Option (rounded
to the nearest whole number of shares of Acquiror Common Stock), at a price per
share equal to the aggregate exercise price for the shares of Company Common
Stock subject to such Company Stock Option divided by the number of whole shares
of Acquiror Common Stock deemed to be purchasable pursuant to such Company Stock
Option; provided, however, that in the case of any Company Stock Option to which
Section 421 of the Code applies by reason of its qualification under Section 422
or Section 423 of the Code ("Qualified Stock Options"), the option price, the
number of shares purchasable pursuant to such Company Stock Option and the terms
and conditions of exercise of such Company Stock Option shall be determined in
order to comply with Section 424 of the Code. Acquiror shall comply with the
terms of the Company Option Plans and the terms of the Company Stock Options
issued other than pursuant to the Company Option Plans as they apply to the
Company Stock Options assumed as set forth above.
 
     (b) Acquiror shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Acquiror Common Stock for delivery
upon exercise of the Company Stock Options assumed in accordance with this
Section 5.7. Acquiror shall file a registration statement on Form S-8 (or any
successor form) or another appropriate form, effective as of the Effective Time,
with respect to shares of Acquiror Common Stock subject to such Company Stock
Options and shall use its best efforts to maintain the effectiveness of such
registration statement or registration statements (and maintain the current
status of the prospectus or prospectuses contained therein) for so long as such
Company Stock Options remain outstanding. With respect to those individuals who
subsequent to the Merger will be subject to the reporting requirements under
Section 16(a) of the Exchange Act, Acquiror shall administer the Company Option
Plans and the Company Stock Options assumed pursuant to this Section 5.7 in a
manner that complies with Rule 16b-3 promulgated under the Exchange Act.
 
     5.8   Indemnification; Directors' and Officers' Liability.
 
     (a) From and after the Effective Time, the Surviving Corporation shall
indemnify, defend and hold harmless to the fullest extent permitted by Ohio law
and provided under the Company's Articles of Incorporation and Code of
Regulations as of the date of the Agreement, and Acquiror shall indemnify,
defend and hold harmless to the fullest extent permitted under Delaware law each
person who is now, or has been at any time prior to the date hereof, an officer
or director of the Company (individually, an "Indemnified Party" and
collectively, the "Indemnified Parties"), against all losses, claims, damages,
 
                                      A-55
<PAGE>   220
 
liabilities, costs or expenses (including attorneys' fees), judgments, fines,
penalties and amounts paid in settlement of or otherwise in connection with any
Claim arising out of or pertaining to acts or omissions, or alleged acts or
omissions, by them in their capacities as such occurring at or prior to the
Effective Time (including, without limitation, the transactions contemplated by
this Agreement and the Option Agreement and, with respect to the Surviving
Corporation, the Company's Articles of Incorporation and Code of Regulations).
In the event of any such Claim, Acquiror shall pay expenses in advance of the
final disposition of any such action or proceeding to each Indemnified Party to
the fullest extent permitted under the DGCL, upon receipt from the Indemnified
Party to whom expenses are advanced of the undertaking to repay such advances
contemplated by Section 145(e) of the DGCL.
 
     (b) Acquiror shall cause the Surviving Corporation to keep in effect
provisions in its Articles and Code of Regulations with respect to
indemnification identical to such provisions contained in the Articles and Code
of Regulations of the Company on the date hereof, 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 adversely affect the rights thereunder
of individuals who at any time prior to the Effective Time were directors or
officers of the Company in respect of actions or omissions at or prior to the
Effective Time (including, without limitation, the transactions contemplated by
this Agreement and the Option Agreement), except as required by applicable law
or except to make changes permitted by law that would not materially diminish
the Indemnified Parties' right of indemnification.
 
     (c) For a period of six years after the Effective Time, Acquiror shall
cause to be maintained in effect the current officers' and directors' liability
insurance maintained by the Company with respect to those persons who are
currently covered by the Company's directors' and officers' liability insurance
policy (provided that Acquiror may substitute therefor policies of at least the
same coverage and amounts containing terms and conditions which are no less
advantageous to such persons than such existing insurance) covering acts or
omissions occurring prior to the Effective Time; provided, however, that
Acquiror shall not be required in order to maintain or procure such coverage to
pay an annual premium in excess of 150% of the current annual premium paid by
the Company for its existing coverage (the "Cap"); and provided, further, that
if existing coverage cannot be maintained or equivalent coverage cannot be
obtained, or can be obtained only by paying an annual premium in excess of the
Cap, Acquiror shall only be required to obtain as much coverage as can be
obtained by paying an annual premium equal to the Cap. The current annual
premium paid by the Company for its existing coverage is set forth in Section
5.8(c) of the Company Disclosure Schedule.
 
     (d) This Section 5.8 shall survive the closing of all of the transactions
contemplated hereby, is intended to benefit the officers and directors of the
Company at the Effective Time and each of the Indemnified Parties and their
respective heirs and personal representatives (each of which shall be entitled
to enforce this Section 5.8 against Acquiror and the Surviving Corporation, as
the case may be, as a third-party beneficiary
 
                                      A-56
<PAGE>   221
 
of this Agreement), and shall be binding on all successors and assigns of
Acquiror and the Surviving Corporation.
 
     5.9   Confidentiality.  The Confidentiality Agreements are hereby affirmed
by Acquiror and the Company and the terms thereof are herewith incorporated
herein by reference and shall continue in full force and effect until the
Effective Time shall have occurred, and if this Agreement is terminated or if
the Effective Time shall not have occurred for any reason whatsoever, the
Confidentiality Agreements shall thereafter remain in full force and effect in
accordance with their terms; provided, however, to the extent there are any
provisions in the Confidentiality Agreements inconsistent with the terms of this
Agreement, the terms of this Agreement shall control.
 
     5.10   Best Efforts.
 
     (a) Subject to the terms and conditions herein provided, the parties hereto
shall: (i) promptly make their respective filings, and thereafter make any other
required submissions, with respect to this Agreement and the Merger required
under (A) the Securities Act (in the case of Acquiror) and the Exchange Act and
the rules and regulations thereunder, and any other applicable federal or state
securities laws, (B) the HSR Act and (C) any other applicable Laws; (ii) use
their respective best efforts to cooperate with one another in (A) determining
which filings are required to be made prior to the Effective Time with, and
which consents, approvals, permits or authorizations ("Third Party Consents")
are required to be obtained prior to the Effective Time from, Governmental
Entities or other third parties in order for the consummation by the parties
hereto and their respective subsidiaries of the transactions contemplated hereby
and (B) timely making all such filings and timely seeking all such Third Party
Consents and (iii) use their respective best efforts to take, or cause to be
taken, all other action and do, or cause to be done, all other things necessary,
proper or appropriate to consummate promptly and make effective the transactions
contemplated by this Agreement. If, at any time after the Effective Time, any
further action is necessary or desirable to carry out the purpose of this
Agreement, the proper officers and directors of the parties hereto shall
promptly take all such necessary action. 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, their respective best efforts
to obtain promptly 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. Acquiror will
use its best efforts to consummate the acquisition of the Meditrust Investments
(as defined below) substantially in accordance with the terms of the letter
agreement dated October 16, 1998 between the Acquiror and Meditrust Mortgage
Investments, Inc., including, if necessary, instituting legal proceedings to
enforce its rights under such agreement. In the event that, despite its best
efforts, Acquiror is unable to so consummate such acquisition by the Closing
Date, Acquiror and
 
                                      A-57
<PAGE>   222
 
the Company will use their best efforts to obtain the consent of Meditrust
Mortgage Investments, Inc. or its affiliates to the Merger.
 
     (b) No party hereto shall take any action for the purpose of delaying,
impairing or impeding the receipt of any Third Party Consent, or the making of
any required filing or registration. Each party hereto shall use its respective
best efforts (x) to overturn or vacate any Law or Order (as defined in Section
7.1(b)) (whether temporary, preliminary or permanent) enacted, issued,
promulgated, enforced or entered by any Governmental Entity or federal or state
court of competent jurisdiction which is in effect and has the effect of making
the Merger illegal or otherwise prohibiting consummation of the transactions
contemplated by this Agreement and (y) to remove any condition or term of any
Order or Third Party Consent (or proposed Order or Third Party Consent) that, in
the reasonable view of either Acquiror or the Company, would be unreasonably
burdensome to Acquiror and Company, on a combined basis, after the Effective
Time.
 
     5.11   Certification of Shareholder Vote.  At or prior to the Closing of
the transactions contemplated by this Agreement, the Company shall deliver to
Acquiror a certificate of its Secretary setting forth the number of shares of
Company Common Stock, voted in favor of adoption of this Agreement and
consummation of the Merger and the number of shares of Company Common Stock
voted against adoption of this Agreement and consummation of the Merger.
 
     5.12   Affiliate Agreements.  Not fewer than 45 days prior to the Effective
Time, the Company shall deliver to Acquiror a list of names and addresses of
each person who was, in the Company's reasonable judgment, at the record date
for the Company Stockholders' Meeting, an "affiliate" of the Company within the
meaning of Rule 145 promulgated under the Securities Act (a "Company
Affiliate"). The Company shall provide Acquiror such information and documents
as Acquiror shall reasonably request for purposes of reviewing such list. The
Company shall use its best efforts to cause each person who may be deemed to be
a Company Affiliate to deliver or cause to be delivered to Acquiror, not later
than 30 days prior to the Effective Time, an affiliate agreement substantially
in the form attached hereto as Exhibit C (each, a "Company Affiliate
Agreement"), executed by each of the Company Affiliates identified in the above-
referenced list.
 
     5.13   Listing Application.  Acquiror shall promptly prepare and submit to
Nasdaq a listing application covering the shares of Acquiror Common Stock
issuable in the Merger and pursuant to the exercise of Company Stock Options,
and shall use its best efforts to obtain, prior to the Effective Time, approval
for the inclusion in Nasdaq of such Acquiror Common Stock, subject to official
notice of issuance.
 
     5.14   Supplemental Disclosure Schedules.  Each of Acquiror and the Company
shall supplement their respective Disclosure Schedules delivered in connection
with this Agreement as of the Closing Date to the extent necessary to reflect
matters permitted by, or consented to by, the other party under this Agreement.
In addition, from time to time prior to the Closing Date, each of Acquiror and
the Company will promptly deliver to the other party such amended or
supplemental Disclosure Schedules as may be
 
                                      A-58
<PAGE>   223
 
necessary to make the Schedules accurate and complete in all material respects
as of the Closing Date; provided, however, that no such disclosure shall have
any effect for the purpose of determining the accuracy of any representation or
warranty given by either party hereto to the other party hereto or the
satisfaction of the conditions set forth in Article VI of this Agreement.
 
     5.15   No Action.  Except as contemplated by this Agreement, no party
hereto will, nor will such party permit any of its respective subsidiaries to,
take or agree or commit to take any action that could reasonably be expected to,
result in (i) any of the representations and warranties of such party set forth
in this Agreement becoming untrue or inaccurate in any material respect at the
date made (to the extent so limited) or as of the Closing Date, or (ii) any of
the conditions to the Merger set forth in Article VI not being satisfied.
 
     5.16   Advice of Changes.  Acquiror and the Company shall promptly advise
the other party orally and in writing to the extent it has knowledge of any
change or event having, or which, insofar as can reasonably be foreseen, would
reasonably be expected to have a Material Adverse Effect on Acquiror or the
Company, as the case may be, or on the truth of their respective representations
and warranties or the ability of the conditions set forth in Article VI to be
satisfied; provided, however, that no such notification shall have any effect on
the representations, warranties, covenants or agreements of the parties (or
remedies with respect thereto) or the conditions to the obligations of the
parties under this Agreement.
 
     5.17   Option and Shareholder Agreements.  Concurrently with the execution
and delivery of this Agreement, (i) Acquiror and the Company have executed and
delivered the Option Agreement in the form attached hereto as Exhibit A (the
"Option Agreement") and (ii) Acquiror and the other parties shall have executed
and delivered the Shareholder Agreements in the form attached hereto as Exhibit
B.
 
     5.18   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 its respective best 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 a tax-free
transaction under the Code. Following the Effective Time, and consistent with
any such consent, neither the Surviving Corporation nor Acquiror 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.
 
                                      A-59
<PAGE>   224
 
     5.19   Possible Acquiror Loan.  Acquiror agrees to make available promptly
to the Company a fully secured line of credit in the principal amount of up to
$10 million on the terms and conditions set forth in the commitment letter
attached as Annex A hereto subject to good faith negotiation, execution and
delivery of mutually acceptable loan documentation consistent with such
commitment letter (the "Acquiror Loan").
 
     5.20   Election of JMAC, Inc. Designee.  Acquiror agrees that (a) as soon
as reasonably practicable following the Effective Time, so long as JMAC, Inc.
beneficially owns at least 500,000 shares of Acquiror Common Stock, Acquiror
will increase by one the size of the entire Board of Directors of Acquiror and
use its best efforts to elect or appoint a designee of JMAC, Inc., who is
reasonably acceptable to the Board of Directors of Acquiror, to fill such newly
created directorship and (b) following the initial term of such director, so
long as JMAC, Inc. beneficially owns at least 500,000 shares of Acquiror Common
Stock, Acquiror will nominate or renominate a designee of JMAC, Inc., who is
reasonably acceptable to the Board of Directors of Acquiror, and use its best
efforts to cause the election of such designee by the stockholders of Acquiror;
provided, however, it shall be a requirement of election or appointment under
clause (a) and nomination or renomination under clause (b) that such designee
shall execute and deliver to the Acquiror a letter stating that if such designee
becomes a member of the Board of Directors of Acquiror, such designee resigns as
a director effective upon receiving notice that JMAC, Inc. beneficially owns
less than 500,000 shares of Acquiror Common Stock. Acquiror agrees that either
Richard R. Slager or Pete A. Klisares is acceptable as a designee of JMAC, Inc.
for this purpose.
 
     5.21   Employee Benefits.
 
     (a) It is Acquiror's current intention that, within a reasonable time after
the Effective Time, employees of the Company and the Company Subsidiaries
("Covered Employees") shall be eligible to participate in all employee benefit
and compensation plans, programs and arrangements maintained, sponsored or
contributed to by the Acquiror (the "Acquiror Plans") on the same terms as any
such Acquiror Plan is offered to similarly situated employees of the Acquiror.
For purposes of all Acquiror Plans, including severance plans or policies, the
Acquiror shall cause each such plan, program or arrangement to treat the prior
service of each Covered Employee with the Company or the Company Subsidiaries as
service rendered to the Acquiror for purposes of eligibility, vesting and
benefit accruals under any Acquiror Plan (but not for purposes of benefit
accruals under any defined benefit or defined contribution pension plan). To the
extent Covered Employees are participating in an Acquiror welfare benefit plan,
the Acquiror will use its best efforts to (i) cause any and all pre-existing
condition limitations and eligibility waiting periods under such welfare benefit

Breach"); provided that, if such Terminating Company Breach is curable by the
Company through the exercise of its best efforts, then, for so long as the

Section 6.1(b) by action of the Board of Directors of the Company evidenced by
notice given by the Company to Acquiror if there has been a breach of any
representation, warranty, covenant or agreement on the part of Acquiror set
forth in this Agreement, or if any representation or warranty of Acquiror shall
have become untrue, in either case such that the conditions in Section 6.2(a) or
Section 6.2(b) would not be satisfied (a "Terminating Acquiror Breach");
provided that, if such Terminating Acquiror Breach is curable by Acquiror
through the exercise of its best efforts and for so long as Acquiror continues
to exercise such best efforts (and as long as such breach is cured within 30
days after the date Acquiror is notified by the Company of such breach), the
Company may not terminate this Agreement under this Section 7.1(d).

however, that nothing herein shall relieve any party from liability for the
willful and material breach of any of its representations, warranties, covenants
or agreements set forth in this Agreement, or from any obligation under the
Confidentiality Agreement.

Agreement may be amended by the parties hereto solely by action taken by their
respective Boards of Directors at any time prior to the Effective Time;
provided, however, that after the approval and adoption of this Agreement by the

amount or change the type of consideration into which each Company Share shall
be converted pursuant hereto or (ii) by Law requires further approval by the
shareholders of the Company without the further approval of such shareholders.

other party contained herein or in any documents delivered pursuant hereto, and
(iii) waive compliance by the other party with any of the agreements or
conditions herein. Any agreement on the part of a party hereto to any such
extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party. No waiver by either party of any default with
respect to any provision, condition or requirement hereof shall be deemed to be
a waiver of any other provision, condition or requirement hereof; nor shall any
delay or omission of either party to exercise any right hereunder in any manner
impair the exercise of any such right accruing to it thereunder.
 
     8.3   Survival.  All representations, warranties and agreements contained

Members of the Board:
 
     BT Alex. Brown Incorporated ("BT Alex. Brown") has acted as financial
advisor to Karrington Health, Inc. ("Karrington") in connection with the
proposed merger transaction involving Karrington and Sunrise Assisted Living,
Inc. ("Sunrise") pursuant to the Agreement and Plan of Merger, dated as of
October 18, 1998, as amended as of March 4, 1999 (as amended, the "Merger
Agreement"), among Sunrise, Buckeye Merger Corporation, a wholly owned
subsidiary of Sunrise ("Merger Sub"), and Karrington. The Merger Agreement
provides, among other things, for the merger of Merger Sub with and into
Karrington (the "Merger") pursuant to which Karrington will become a wholly
owned subsidiary of Sunrise. As set forth more fully in the Merger Agreement, as
a result of the Merger, each outstanding share of the common stock, no par
value, of Karrington ("Karrington Common Stock") will be converted into the
right to receive 0.3333 of a share (the "Exchange Ratio") of the common stock,
par value $0.01 per share, of Sunrise ("Sunrise Common Stock").
 
     You have requested BT Alex. Brown's opinion as to the fairness, from a
financial point of view, of the Exchange Ratio to the holders of Karrington
Common Stock.
 
     In connection with BT Alex. Brown's role as financial advisor to
Karrington, and in arriving at its opinion, BT Alex. Brown has reviewed certain
publicly available financial and other information concerning Karrington and
Sunrise and certain internal analyses and other information furnished to or
discussed with it by Karrington, Sunrise and their respective advisors. BT Alex.
Brown has also held discussions with members of the senior management of
Karrington and Sunrise regarding the business and prospects of their respective
companies and the joint prospects of a combined company. In addition, BT Alex.
Brown has (i) reviewed the reported prices and trading activity for Karrington
Common Stock and Sunrise Common Stock, (ii) compared certain financial and stock
market information for Karrington and Sunrise with similar information for
certain other companies whose securities are publicly traded, (iii) reviewed the
financial terms of certain recent business combinations which it deemed
comparable in whole or in part, (iv) reviewed the terms of the Merger Agreement
and certain related documents, and (v) performed such other studies and analyses
and considered such other factors as it deemed appropriate.

     BT Alex. Brown has not assumed responsibility for independent verification
of, and has not independently verified, any information, whether publicly
available or furnished to it, concerning Karrington, Sunrise or the combined
company, including, without limitation, any financial information, forecasts or
projections considered in connection with the rendering of its opinion.
Accordingly, for purposes of its opinion, BT Alex. Brown has assumed and relied
upon the accuracy and completeness of all such information and BT Alex. Brown
has not conducted a physical inspection of any of the properties or assets, and
has not prepared or obtained any independent evaluation or appraisal of any of
the assets or liabilities, of Karrington or Sunrise. With respect to the
financial forecasts and projections made available to BT Alex. Brown and used in
its analyses, including the analyses and forecasts of certain synergies expected
by Sunrise and Karrington to be achieved as a result of the Merger, BT Alex.
Brown has assumed that they have been reasonably prepared on bases reflecting
the best currently available estimates and judgments of the management of
Karrington or Sunrise, as the case may be, as to the matters covered thereby. In
rendering its opinion, BT Alex. Brown expresses no view as to the reasonableness
of such forecasts and projections, including the synergies, or the assumptions
on which they are based. BT Alex. Brown's opinion is necessarily based upon
economic, market and other conditions as in effect on, and the information made
available to it as of, the date hereof.
 
     For purposes of rendering its opinion, BT Alex. Brown has assumed that, in
all respects material to its analysis, the representations and warranties of
Karrington, Sunrise and Merger Sub contained in the Merger Agreement are true
and correct, Karrington, Sunrise and Merger Sub will each perform all of the
covenants and agreements to be performed by it under the Merger Agreement and
all conditions to the obligations of each of Karrington, Sunrise and Merger Sub
to consummate the Merger will be satisfied without any waiver thereof. BT Alex.
Brown has also assumed that all material governmental, regulatory or other
approvals or consents required in connection with the consummation of the Merger
will be obtained and that in connection with obtaining any necessary
governmental, regulatory or other approvals or consents, or any amendments,
modifications or waivers to any agreements, instruments or orders to which
either Karrington or Sunrise is a party or is subject or by which it is bound,
no limitations, restrictions or conditions will be imposed or amendments,
modifications or waivers made that would have a material adverse effect on
Karrington or Sunrise or materially reduce the contemplated benefits of the
Merger to Karrington. In addition, you have informed BT Alex. Brown, and
accordingly for purposes of rendering its opinion BT Alex. Brown has assumed,
that the Merger will qualify as a tax-free reorganization for federal income tax
purposes. In connection with its engagement, BT Alex. Brown was not authorized
to, and did not solicit interest from any other party with respect to the
acquisition of all or a

part of Karrington. BT Alex. Brown is expressing no opinion as to the price at
which the Sunrise Common Stock will trade at any time.
 
     This opinion is addressed to, and for the use and benefit of, the Board of
Directors of Karrington and is not a recommendation to any shareholder as to how
such shareholder should vote with respect to matters relating to the proposed
Merger. This opinion is limited to the fairness, from a financial point of view,
of the Exchange Ratio to the holders of Karrington Common Stock, and BT Alex.
Brown expresses no opinion as to the merits of the underlying decision by
Karrington to engage in the Merger.
 
     BT Alex. Brown, as a customary part of its investment banking business, is
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, private placements and
valuations for estate, corporate and other purposes. We have acted as financial
advisor to Karrington in connection with the Merger and will receive a fee for
our services, a significant portion of which is contingent upon the consummation
of the Merger and a portion of which is payable upon delivery of this opinion.
BT Alex. Brown has in the past provided financial services to Karrington and
Sunrise unrelated to the proposed Merger, for which services BT Alex. Brown has
received customary compensation. BT Alex. Brown maintains a market in both
 
     Karrington Common Stock and Sunrise Common Stock and regularly publishes
research reports regarding the businesses and securities of Karrington and
Sunrise and other publicly traded companies in the assisted living industry. In
the ordinary course of business, BT Alex. Brown and its affiliates may actively
trade or hold the securities and other instruments and obligations of Karrington
and Sunrise for their own account and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities,
instruments or obligations.
 
     Based upon and subject to the foregoing, it is BT Alex. Brown's opinion
that, as of the date of this letter, the Exchange Ratio is fair, from a
financial point of view, to the holders of Karrington Common Stock.
 
                                          Very truly yours,
 
                                          BT ALEX. BROWN INCORPORATED

                         OHIO REVISED CODE SEC. 1701.85
 
  SEC. 1701.85 DISSENTING SHAREHOLDER'S DEMAND FOR FAIR CASH VALUE OF SHARES.
 
     (A)(1) A shareholder of a domestic corporation is entitled to relief as a
dissenting shareholder in respect of the proposals described in sections
1701.74, 1701.76, and 1701.84 of the Revised Code, only in compliance with this
section.
 
     (2) If the proposal must be submitted to the shareholders of the
corporation involved, the dissenting shareholder shall be a record holder of the
shares of the corporation as to which he seeks relief as of the date fixed for
the determination of shareholders entitled to notice of a meeting of the
shareholders at which the proposal is to be submitted, and such shares shall not
have been voted in favor of the proposal. Not later than ten days after the date
on which the vote on the proposal was taken at the meeting of the shareholders,
the dissenting shareholder shall deliver to the corporation a written demand for
payment to him of the fair cash value of the shares as to which he seeks relief,
which demand shall state his address, the number and class of such shares, and
the amount claimed by him as the fair cash value of the shares.
 
     (3) The dissenting shareholder entitled to relief under division (C) of
section 1701.84 of the Revised Code in the case of a merger pursuant to section
1701.80 of the Revised Code and a dissenting shareholder entitled to relief
under division (E) of section 1701.84 of the Revised Code in the case of a
merger pursuant to section 1701.801 [1701.80.1] of the Revised Code shall be a
record holder of the shares of the corporation as to which he seeks relief as of
the date on which the agreement of merger was adopted by the directors of that
corporation. Within twenty days after he has been sent the notice provided in
section 1701.80 or 1701.801 [1701.80.1] of the Revised Code, the dissenting
shareholder shall deliver to the corporation a written demand for payment with
the same information as that provided for in division (A)(2) of this section.
 
     (4) In the case of a merger or consolidation, a demand served on the
constituent corporation involved constitutes service on the surviving or the new
entity, whether the demand is served before, on, or after the effective date of
the merger or consolidation.
 
     (5) If the corporation sends to the dissenting shareholder, at the address
specified in his demand, a request for the certificates representing the shares
as to which he seeks relief, the dissenting shareholder, within fifteen days
from the date of the sending of such request, shall deliver to the corporation
the certificates requested so that the corporation may forthwith endorse on them
a legend to the effect that demand for the fair cash value of such shares has
been made. The corporation promptly shall return such endorsed certificates to
the dissenting shareholder. A dissenting shareholder's failure to deliver such
certificates terminates his rights as a dissenting shareholder, at the option of
the corporation, exercised by written notice sent to the dissenting shareholder
within
 
                                       D-1
<PAGE>   247
 
twenty days after the lapse of the fifteen-day period, unless a court for good
cause shown otherwise directs. If shares represented by a certificate on which
such a legend has been endorsed are transferred, each new certificate issued for
them shall bear a similar legend, together with the name of the original
dissenting holder of such shares. Upon receiving a demand for payment from a
dissenting shareholder who is the record holder of uncertificated securities,
the corporation shall make an appropriate notation of the demand for payment in
its shareholder records. If uncertificated shares for which payment has been
demanded are to be transferred, any new certificate issued for the shares shall
bear the legend required for certificated securities as provided in this
paragraph. A transferee of the shares so endorsed, or of uncertificated
securities where such notation has been made, acquires only such rights in the
corporation as the original dissenting holder of such shares had immediately
after the service of a demand for payment of the fair cash value of the shares.
A request under this paragraph by the corporation is not an admission by the
corporation that the shareholder is entitled to relief under this section.
 
     (B) Unless the corporation and the dissenting shareholder have come to an
agreement on the fair cash value per share of the shares as to which the
dissenting shareholder seeks relief, the dissenting shareholder or the
corporation, which in case of a merger or consolidation may be the surviving or
new entity, within three months after the service of the demand by the
dissenting shareholder, may file a complaint in the court of common pleas of the
county in which the principal office of the corporation that issued the shares
is located or was located when the proposal was adopted by the shareholders of
the corporation, or, if the proposal was not required to be submitted to the
shareholders, was approved by the directors. Other dissenting shareholders,
within that three-month period, may join as plaintiffs or may be joined as
defendants in any such proceeding, and any two or more such proceedings may be
consolidated. The complaint shall contain a brief statement of the facts,
including the vote and the facts entitling the dissenting shareholder to the
relief demanded. No answer to such a complaint is required. Upon the filing of
such a complaint, the court, on motion of the petitioner, shall enter an order
fixing a date for a hearing on the complaint and requiring that a copy of the
complaint and a notice of the filing and of the date for hearing be given to the
respondent or defendant in the manner in which summons is required to be served
or substituted service is required to be made in other cases. On the day fixed
for the hearing on the complaint or any adjournment of it, the court shall
determine from the complaint and from such evidence as is submitted by either
party whether the dissenting shareholder is entitled to be paid the fair cash
value of any shares and, if so, the number and class of such shares. If the
court finds that the dissenting shareholder is so entitled, the court may
appoint one or more persons as appraisers to receive evidence and to recommend a
decision on the amount of the fair cash value. The appraisers have such power
and authority as is specified in the order of their appointment. The court
thereupon shall make a finding as to the fair cash value of a share and shall
render judgment against the corporation for the payment of it, with interest at
such rate and from such date as the court considers equitable. The costs of the
proceeding, including reasonable compensation to the appraisers to be fixed by
the court, shall be assessed or
 
                                       D-2
<PAGE>   248
 
apportioned as the court considers equitable. The proceeding is a special
proceeding and final orders in it may be vacated, modified, or reversed on
appeal pursuant to the Rules of Appellate Procedure and, to the extent not in
conflict with those rules, Chapter 2505. of the Revised Code. If, during the
pendency of any proceeding instituted under this section, a suit or proceeding
is or has been instituted to enjoin or otherwise to prevent the carrying out of
the action as to which the shareholder has dissented, the proceeding instituted
under this section shall be stayed until the final determination of the other
suit or proceeding. Unless any provision in division (D) of this section is
applicable, the fair cash value of the shares that is agreed upon by the parties
or fixed under this section shall be paid within thirty days after the date of
final determination of such value under this division, the effective date of the
amendment to the articles, or the consummation of the other action involved,
whichever occurs last. Upon the occurrence of the last such event, payment shall
be made immediately to a holder of uncertificated securities entitled to such
payment. In the case of holders of shares represented by certificates, payment
shall be made only upon and simultaneously with the surrender to the corporation
of the certificates representing the shares for which the payment is made.
 
     (C) If the proposal was required to be submitted to the shareholders of the
corporation, fair cash value as to those shareholders shall be determined as of
the day prior to the day on which the vote by the shareholders was taken and, in
the case of a merger pursuant to section 1701.80 or 1701.801 [1701.80.1] of the
Revised Code, fair cash value as to shareholders of a constituent subsidiary
corporation shall be determined as of the day before the adoption of the
agreement of merger by the directors of the particular subsidiary corporation.
The fair cash value of a share for the purposes of this section is the amount
that a willing seller who is under no compulsion to sell would be willing to
accept and that a willing buyer who is under no compulsion to purchase would be
willing to pay, but in no event shall the fair cash value of a share exceed the
amount specified in the demand of the particular shareholder. In computing such
fair cash value, any appreciation or depreciation in market value resulting from
the proposal submitted to the directors or to the shareholders shall be
excluded.
 
     (D)(1) The right and obligation of a dissenting shareholder to receive such
fair cash value and to sell such shares as to which he seeks relief, and the
right and obligation of the corporation to purchase such shares and to pay the
fair cash value of them terminates if any of the following applies:
 
         (a) The dissenting shareholder has not complied with this section,
     unless the corporation by its directors waives such failure;
 
         (b) The corporation abandons the action involved or is finally enjoined
     or prevented from carrying it out, or the shareholders rescind their
     adoption of the action involved;
 
         (c) The dissenting shareholder withdraws his demand, with the consent
     of the corporation by its directors;
 
                                       D-3
<PAGE>   249
 
         (d) The corporation and the dissenting shareholder have not come to an
     agreement as to the fair cash value per share, and neither the shareholder
     nor the corporation has filed or joined in a complaint under division (B)
     of this section within the period provided in that division.
 
     (2) For purposes of division (D)(1) of this section, if the merger or
consolidation has become effective and the surviving or new entity is not a
corporation, action required to be taken by the directors of the corporation
shall be taken by the general partners of a surviving or new partnership or the
comparable representatives of any other surviving or new entity.
 
     (E) From the time of the dissenting shareholder's giving of the demand
until either the termination of the rights and obligations arising from it or
the purchase of the shares by the corporation, all other rights accruing from
such shares, including voting and dividend or distribution rights, are
suspended. If during the suspension, any dividend or distribution is paid in
money upon shares of such class or any dividend, distribution, or interest is
paid in money upon any securities issued in extinguishment of or in substitution
for such shares, an amount equal to the dividend, distribution, or interest
which, except for the suspension, would have been payable upon such shares or
securities, shall be paid to the holder of record as a credit upon the fair cash
value of the shares. If the right to receive fair cash value is terminated other
than by the purchase of the shares by the corporation, all rights of the holder
shall be restored and all distributions which, except for the suspension, would
have been made shall be made to the holder of record of the shares at the time
of termination.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Under Section 145 of the Delaware General Corporation Law, a corporation
may indemnify its directors, officers, employees and agents and its former
directors, officers, employees and agents and those who serve, at the
corporation's request, in such capacities with another enterprise, against
expenses, including attorneys' fees, as well as judgments, fines and settlements
in non-derivative lawsuits, actually and reasonably incurred in connection with
the defense of any action, suit or proceeding in which they or any of them were
or are made parties or are threatened to be made parties by reason of their
serving or having served in such capacity. The Delaware General Corporation Law
provides, however, that such person must have acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the best
interests of the corporation and, in the case of a criminal action, such person
must have had no reasonable cause to believe his or her conduct was unlawful. In
addition, the Delaware General Corporation Law does not permit indemnification
in an action or suit by or in the right of the corporation, where such person
has been adjudged liable to the corporation, unless, and only to the extent
that, a court determines that such person fairly and reasonably is entitled to
indemnity for expenses the court deems proper in light of liability
adjudication. Indemnity is mandatory to the extent a claim, issue or matter has
been successfully defended.
 
     The Company's bylaws provide for mandatory indemnification of directors and
officers generally to the same extent authorized by the Delaware General
Corporation Law. Under the bylaws, the Company must advance expenses incurred by
a director or officer in defending any such action if the director of officer
undertakes to repay such amount if it is determined that he or she is not
entitled to indemnification.
 
     The Company has entered into separate indemnification agreements with its
directors and officers. Each indemnification agreement provides for, among other
things: (i) indemnification against any and all expenses, liabilities and
losses, including attorneys' fees, judgments, fines, taxes, penalties and
amounts paid in settlement, of any claim against an indemnified party unless it
is determined, as provided in the indemnification agreement, that
indemnification is not permitted under applicable law and (ii) prompt
advancement of expenses to any indemnified party in connection with his or her
defense against any claim.
 
     The Company also maintains directors' and officers' liability insurance.

(b) Financial Statement Schedules
 
     Schedules have been omitted because the information required to be set
forth therein is not applicable or is included elsewhere in the Sunrise
financial statements or the notes thereto.
 
ITEM 22.  UNDERTAKINGS.
 
     The Registrant hereby undertakes:
 
         (a) 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.
 
         (b) that every prospectus (i) that is filed pursuant to paragraph (a)
     immediately preceding, or (ii) that purports to meet the requirements of
     Section 10(a)(3) of the Securities Act of 1933, as amended and is used in
     connection with an offering of securities subject to Rule 415, will be
     filed as a part of an amendment to the registration statement and will not
     be used until such amendment is effective, and that, for purposes of
     determining any liability under the Securities Act, each such
     post-effective amendment shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.
 
         (c) that, for purposes of determining any liability under the
     Securities Act, each filing of the registrant's annual report pursuant to
     Section 13(a) or 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, that is
     incorporated by reference in this registration statement shall be deemed to
     be a new registration statement relating to the securities offered therein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.
 
         (d) insofar as indemnification for liabilities arising under the
     Securities Act may be permitted to directors, officers or persons
     controlling the registrant pursuant to the foregoing provisions, the
     registrant has been informed that in the opinion of the SEC such
     indemnification is against public policy as expressed in the Securities Act
     and is therefore unenforceable. In the event that a claim for
     indemnification against such liabilities, other than the payment by the
     registrant for 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
 
                                      II-4
<PAGE>   254
 
     controlling precedent, submit to a court of appropriate jurisdiction the
     question whether such indemnification by it is against public policy as
     expressed in the Securities Act and will be governed by the final
     adjudication of such issue.
 
         (e) to respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this
     form, within one business day of receipt of such request, and to send the
     incorporated documents by first class mail or other equally prompt means.
     This includes information contained in documents filed subsequent to the
     effective date of this Registration Statement through the date of
     responding to the request.
 
         (f) to supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved therein,
     that was not the subject of and included in this registration statement
     when it became effective.
