 Purpose of the Special Meeting (Page 12)

   At the special meeting, InSight stockholders will be asked to consider and
vote upon proposals to approve:

  .  the merger agreement; and

  .  any other matters that are properly brought before the special meeting
     or any adjournment or postponement of the meeting.

   We cannot complete the merger unless the merger agreement is approved by the
InSight stockholders.

 Stockholders Entitled to Vote (Page 12)

   Holders of record of shares of InSight common stock and InSight preferred
stock at the close of business on the record date are entitled to notice of,
and to vote at, the special meeting. On the record date, there were     shares
of InSight common stock outstanding, which includes the preferred shares (on an
as-if-converted basis), each of which will be entitled to one vote on each
matter to be acted upon at the special meeting. On the record date, there were
       shares of InSight Series D preferred stock outstanding, which may be
converted into    shares of InSight common stock.

 Vote Required (Page 12)

   The approval of the merger agreement will require the affirmative vote of
the holders of a majority of the outstanding shares of InSight common stock and
preferred stock, as of the record date, with the holders of InSight preferred
stock voting on an as-if-converted basis.

Voting Agreements (Page 13)

   On June 29, 2001, each of General Electric Company, GE Fund and various
entities affiliated with The Carlyle Group entered into a voting agreement with
InSight Holdings and JWCH Merger Corp. pursuant to which they have agreed,
subject to the terms and conditions of the voting agreement, to vote the shares
of InSight capital stock they beneficially own FOR adoption of the merger
agreement. These InSight stockholders collectively beneficially owned
approximately   % of the outstanding shares of InSight common stock (on an as-
if-converted basis) as of the record date. The voting agreements are attached
hereto as Annex III. General Electric Company, GE Fund and the various entities
affiliated with The Carlyle Group have also granted

                                       2


irrevocable proxies, including a power of attorney, to InSight Holdings and
JWCH Merger Corp. to vote their shares FOR adoption of the merger agreement.
Pursuant to the voting agreements, each of General Electric Company, the GE
Fund and the various entities affiliated with The Carlyle Group agreed to
convert the InSight preferred stock they own into InSight Series D preferred
stock prior to the record date, which has been completed. Such stockholders
also agreed to further convert such Series D preferred stock into common stock
prior to the consummation of the merger. The effect of the voting agreements
described above is that the holders of a majority of the shares of InSight
common stock (including the InSight preferred stock voting on an as-if-
converted basis) have agreed to vote for adoption of the merger agreement.

Security Ownership of Certain Beneficial Owners and Management (Page 45)

   Each of the directors and executive officers of InSight has advised InSight
that he or she intends to vote all shares of InSight common stock he or she
owns FOR adoption of the merger agreement. As of the record date, directors and
executive officers of InSight held and were entitled to vote approximately   %
of the outstanding shares of InSight common stock (assuming the conversion of
InSight preferred stock into common stock).

The Merger (Page 17)

   Upon completion of the merger, JWCH Merger Corp. will be merged with and
into InSight, and InSight will survive the merger and become a wholly-owned
subsidiary of InSight Holdings. Each issued and outstanding share of InSight
common stock will be converted into the right to receive $18 in cash. The
merger agreement provides that each share of InSight preferred stock will be
converted into a share of InSight common stock immediately prior to the
completion of the merger. Accordingly, assuming such conversion of your InSight
preferred stock, you will receive the same per share consideration as the
holders of InSight common stock on an as-if-converted basis.

   The merger agreement provides that holders of InSight stock options and
warrants will receive a cash payment for each option or warrant, whether or not
then exercisable, in an amount equal to the difference between the exercise
price of the option or warrant and the per share consideration received by
holders of InSight common stock in connection with the merger.

 The Board of Directors Recommendation (Page 12)

   The InSight board of directors believes that the merger is fair to, and in
the best interests of, InSight and its stockholders, and unanimously recommends
that holders of InSight capital stock vote FOR approval of the merger
agreement. To review the background and reasons for the merger in greater
detail, see pages 17 and 20.

 Risk Factors Relating to the Merger (Page 9)

   In evaluating the merger and the proposal to adopt the merger agreement, you
should carefully consider the "Risk Factors Relating to the Merger."

 Opinion of InSight's Financial Advisor (Page 21)

   In connection with the merger, the InSight board of directors received a
written opinion from InSight's financial advisor, UBS Warburg LLC, as to the
fairness, from a financial point of view, of the merger consideration to be
received by the holders of InSight common stock. The full text of UBS Warburg's
written opinion dated June 29, 2001 is attached to this proxy statement as
Annex II. We encourage you to read this opinion carefully in its entirety for a
description of the assumptions made, procedures followed, matters considered
and limitations on the review undertaken. UBS Warburg's opinion is addressed to
the InSight board and does not constitute a recommendation to any stockholder
with respect to any matters relating to the proposed merger.

 Interests of InSight's Directors and Executive Officers in the Merger (Page
 27)

   Directors and executive officers of InSight have interests in the merger as
directors or executive officers that are different from, or in addition to,
those of other InSight stockholders. These interests include the following:

  .  the continued indemnification of current directors and officers of
     InSight pursuant to the merger agreement;

  .  the retention of certain executive officers of InSight as employees or
     consultants after the merger is completed pursuant to new employment
     agreements which, in some cases, provide for increased benefits,
     including stock options in InSight Holdings;

  .  options and warrants held by InSight's directors, executive officers and
     employees will become fully vested as a result of the merger;

  .  certain officers of InSight are parties to employment agreements that
     provide for severance payments following a "change in control," such as
     the merger, if such officers terminate his or her employment with
     InSight; and

  .  the affiliation of certain of our directors with InSight's major
     stockholders.

 Financing (Page 29)

   InSight Holdings' and JWCH Merger Corp.'s obligation to complete the merger
is contingent upon, among other things, obtaining the financing for the merger
contemplated by commitment letters obtained by it at the time of execution of
the merger agreement. InSight and InSight Holdings estimate that the total
amount of funds necessary to complete the merger and related transactions is
approximately $475 million. These funds are currently expected to come from the
following sources:

  .  an equity investment by J.W. Childs Equity Partners II, L.P. and Halifax
     Capital Partners, L.P. of up to $81.5 million, net of the value of the
     stock options rolled over by certain executive officers of InSight, and
     $20 million, respectively;

  .  borrowings by InSight in an aggregate amount of up to $150 million under
     a $275 million senior credit facility;

  .  the issuance of $200 million of unsecured senior subordinated notes to
     be issued by JWCH Merger Corp. (which will become obligations of InSight
     upon consummation of the merger of JWCH Merger Corp. with and into
     InSight); and

  .  cash balances of InSight at the closing of the merger which will include
     option and warrant proceeds.

   InSight Holdings is not required to obtain alternative financing if the
financing arrangements listed above do not materialize. Accordingly, no
alternative financing arrangements or alternative financing plans have been
made by InSight Holdings.

     necessary to complete the merger;

  .  obtaining third-party consents, approvals and waivers required to be
     obtained in connection with the transactions contemplated by the merger
     agreement;

  .  there has not been a material adverse effect on InSight;

  .  there is not outstanding any litigation which seeks to enjoin the
     completion of the merger and has a reasonable likelihood of success; and

  .  InSight shall not have indebtedness, net of cash and cash equivalents,
     on a consolidated basis in excess of $222,500,000.

 Termination of the Merger Agreement (Page 43)

   The merger agreement may be terminated as follows:

  .  by mutual written consent of InSight, InSight Holdings and JWCH Merger
     Corp.;

  .  at the option of InSight Holdings, JWCH Merger Corp. or InSight, if (a)
     the merger is not consummated by the later of October 8, 2001 and 35
     days after the completion of the audit of the consolidated financial
     statements of InSight and its subsidiaries for the fiscal year ended
     June 30, 2001 and delivery thereof to InSight Holdings or (b) any court
     or governmental authority shall have issued an order, decree, ruling or
     taken any other action restraining, enjoining or otherwise prohibiting
     the merger and such order, decree, ruling or other action shall have
     become final and nonappealable;

  .  by InSight Holdings, JWCH Merger Corp. or InSight, if the merger is not
     approved by InSight stockholders;

  .  by the InSight board of directors, upon its exercise of the fiduciary-
     out provision contained in the merger agreement, pursuant to which
     InSight may terminate the merger agreement and enter into an agreement
     with a third-party which the InSight board of directors has deemed to be
     superior to the transactions contemplated by the merger agreement;

  .  by InSight, if InSight Holdings or JWCH Merger Corp. materially breaches
     its obligations set forth in the merger agreement, unless such breach is
     cured within 30 days after written notice to InSight Holdings by
     InSight; and

  .  by InSight Holdings or JWCH Merger Corp., if InSight materially breaches
     its obligations set forth in the merger agreement, unless such breach is
     cured within 30 days after written notice to InSight by InSight Holdings
     or JWCH Merger Corp.

                                       5



   Under certain circumstances, InSight may be required to pay InSight Holdings
a termination fee of $7 million or reimburse up to $1 million of InSight
Holdings' and its affiliates' expenses.

 Appraisal Rights (Page 34)

   Any InSight stockholder who does not wish to accept the consideration
provided for in the merger agreement in exchange for his, her or its shares has
the right under the Delaware General Corporation Law to receive the "fair
value" of his, her or its shares of our capital stock as determined by a
Delaware court. This "appraisal right" is subject to a number of restrictions
and technical requirements. Generally, in order to perfect appraisal rights, a
dissenting stockholder must:

  .  not vote in favor of adopting and approving the merger agreement; and

  .  make a written demand for appraisal before the vote on the merger
     agreement.

   Merely voting against the merger agreement and the merger will not protect
the right of appraisal. Annex IV to this proxy statement contains the
applicable provisions of the Delaware General Corporation Law relating to
appraisal rights.

 Certain Material United States Federal Income Tax Consequences of the Merger
 (Page 32)

   The receipt of cash in exchange for shares of InSight common stock pursuant
to the merger will be a taxable transaction for federal income tax purposes,
unless you are exempt from taxes. You are urged to consult your tax advisor to
determine the effect of the merger on you under federal, state, local and
foreign tax laws.

 Regulatory Matters (Page 34)

   United States antitrust laws prohibit InSight and InSight Holdings from
completing the merger until they have furnished certain information and
materials to the Antitrust Division of the Department of Justice and the
Federal Trade Commission and a required waiting period has ended. InSight and
InSight Holdings filed the required notification and report forms with the
Antitrust Division of the Department of Justice and the Federal Trade
Commission on July 6, 2001 and        , 2001, respectively. Under the antitrust
laws, the merger may not be completed until after the expiration or early
termination of the applicable waiting period. The applicable waiting period
expires on      , 2001.

 Procedure for the Exchange of Stock Certificates (Page 36)

   If the merger is completed, a letter of transmittal will be sent to all
holders of record of InSight capital stock, which will contain instructions for
surrendering the holders' stock certificates. Please do not send your stock
certificates with the proxy. You should not surrender your stock until you
receive the letter of transmittal.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: Why is the InSight board of directors recommending that I vote in favor of
   the proposal to adopt the merger agreement?

A: After careful consideration, the InSight board of directors has unanimously
   approved the merger agreement and the merger, and has unanimously determined
   that the merger is advisable and fair to, and in the best interests of, the
   InSight stockholders. In reaching its decision to approve the merger
   agreement and the merger and to recommend adoption of the merger agreement
   by InSight stockholders, the InSight board of directors consulted with
   InSight management, as well as InSight's legal and financial advisors, and
   considered the terms of the proposed merger agreement and the transactions
   contemplated by the merger agreement. The InSight board of directors also
   considered each of the items set forth on pages 20 and 21.

Q: What will I receive in the merger if I own InSight common stock?

A: If the merger is completed, each share of your InSight common stock will be
   converted into the right to receive $18 in cash.

Q: What will I receive in the merger if I own InSight preferred stock?

A: The merger agreement provides that each share of InSight preferred stock
   will be converted into a share of InSight common stock immediately prior to
   the completion of the merger. Accordingly, assuming such conversion of your
   InSight preferred stock, you will receive the same per share consideration
   as the holders of InSight common stock on an as-if-converted basis.

Q: When do you expect the merger to be completed?

A: We are working toward completing the merger as quickly as possible. We
   expect to complete the merger by             , 2001. However, it is possible
   that InSight, InSight Holdings and JWCH Merger Corp. may agree to a later
   date.

Q: What do I need to know?

A: We urge you to read this proxy statement carefully, including its Annexes,
   and to consider how the merger would affect you as a stockholder. You also
   may want to review the documents referenced under "Where You Can Find More
   Information" on page 50.

Q: How do I vote?

A: Please indicate on your proxy card how you want to vote, and sign and mail
   your proxy card in the enclosed postage-paid return envelope as soon as
   possible so that your shares may be represented at the meeting. If you sign
   and send in your proxy card and do not indicate how you want to vote, your
   proxy will be counted as a vote in favor of the merger agreement. If you
   abstain from voting or do not vote your shares by proxy or in person at the
   special meeting, it will have the same effect as a vote against the approval
   of the merger agreement.

Q: If my shares are held in a brokerage account or in "street name" by my
   broker, how will my shares be voted?

A: Your broker will not vote your shares unless you provide your broker with
   written instructions on how to vote. If you do not instruct your broker,
   your shares will not be voted, which will have the same effect as a vote
   against the adoption of the merger agreement. As a result, it is important
   that you follow the directions provided by your broker regarding how to
   instruct your broker to vote your shares.

Q: May I change my vote after I have mailed a signed proxy card?

A: Yes. You may change your vote in one of the following three ways at any time
   before your proxy is voted at the special meeting. First, you may send a
   written notice stating that you would like to revoke your proxy. Second, you
   may complete a new, later-dated proxy card. Third, you can attend the
   meeting and vote in person. If you choose either of the first two methods,
   you must submit your notice of revocation or your new proxy to the Secretary
   of InSight, at the address listed below. If you have instructed a broker to
   vote your shares, you must follow the directions received from your broker
   to change your vote or to vote in person at the special meeting.

Q: Should I send my certificates now?

A: No. After the merger is completed, we will send you written instructions for
   surrendering your stock certificates.

Q: Whom do I call with questions?

A: InSight stockholders who have questions about the merger should contact:

                         InSight Health Services Corp.
                         4400 MacArthur Blvd, Suite 800

                      RISK FACTORS RELATING TO THE MERGER

   In addition to the other information included in this proxy statement,
InSight stockholders should consider carefully the matters described below in
determining whether to adopt the merger agreement.

The cash price per share will not be adjusted for changes in stock prices.

   The cash price per share that InSight stockholders will receive for a share
of InSight capital stock is fixed. The market value of InSight common stock at
the effective time of the merger may vary significantly from the closing price
on the date the merger agreement was executed, the date of this proxy statement
or the date on which the InSight stockholders vote on the merger agreement.
These changes may result from a number of factors, including:

  .  market perception of the merger;

  .  changes in the business, operations or prospects of InSight;

  .  market assessments of the likelihood that the merger will be completed
     and the timing of the merger; and

  .  general market and economic conditions.

   Because the merger consideration will not be adjusted to reflect changes in
the market value of InSight common stock, the cash amount per share paid to
InSight stockholders under the merger agreement may be higher or lower than the
value of InSight common stock at the time the merger was approved by the
InSight board of directors. We are not permitted to terminate the merger
agreement or resolicit the vote of InSight stockholders because of changes in
the market price of the InSight common stock.

Our directors and executive officers have conflicts of interest that may
influence them to support and approve the merger.

   Our directors and executive officers participate in arrangements that
provide them with interests in the merger that are different from, or are in
addition to, your interests as a stockholder.

   Our directors and executive officers hold options and warrants to purchase
shares of InSight common stock that will become fully vested as a result of the
merger. The merger will also trigger certain rights (including monetary
compensation if the executive officer leaves InSight after the merger) under
employment agreements between InSight and some of its executive officers.
Effective as of the closing of the merger, certain of InSight's officers have
entered into new employment agreements which, in some cases, provide for
increased benefits, including stock options in InSight Holdings.

   In addition, certain directors of InSight are designees of General Electric
Company and The Carlyle Group, the owners of the InSight preferred stock. GE
Capital Equity Holdings, Inc., an affiliate of General Electric Company, has
invested a total of $10 million in the $200 million private equity fund managed
by The Halifax Group, L.L.C.

   As a result, our directors and executive officers could be more likely to
vote to approve the merger agreement than if they did not hold these interests.
You should consider whether these interests may have influenced our directors
and executive officers to support and recommend the merger.

If InSight fails to obtain all required consents and waivers, third parties may
terminate or alter existing contracts.

   InSight is required to obtain the consent of, and certain waivers from, its
lenders under its primary bank credit facility in connection with the merger.
If the approvals and waivers are not obtained, the credit facility could be
declared in default and the borrowings under the credit facility would become
immediately due and

                                       9


payable. J.W. Childs and Halifax have arranged financing which will provide
them with the necessary funds to refinance certain of InSight's existing
indebtedness. Please review the section "Financing" on page 29 of this proxy
statement for more information regarding the financing arrangements made by
J.W. Childs and Halifax. To the extent InSight's existing indebtedness is
refinanced, InSight will not be required to obtain consents or waivers from its
existing lenders that are paid in full in connection with the refinancing.

   In addition, certain other agreements with suppliers, customers, licensors
or other business partners may require InSight to obtain the approval or waiver
of these other parties in connection with the merger. Moreover, holders of
certain of our outstanding senior subordinated notes may require InSight to
purchase the outstanding indebtedness under the notes upon the closing of the
merger.

   InSight has agreed to use reasonable efforts to secure the necessary
approvals and waivers. However, we cannot assure you that we will be able to
obtain all of the necessary approvals and waivers.

Failure to complete the merger or delays in completing the merger could
negatively impact InSight's stock price and future business and operations.

   If the merger is not completed for any reason, InSight may be subject to a
number of material risks, including the following:

  .  InSight may be required to pay to InSight Holdings a termination fee of
     $7 million;

  .  InSight may be required to reimburse up to $1 million of the expenses
     incurred by InSight Holdings and its affiliates in connection with the
     merger;

  .  the price of InSight common stock may decline to the extent that the
     current market price of InSight common stock reflects a market
     assumption that the merger will be completed; and

  .  costs related to the merger, such as legal, accounting and financial
     advisor fees, must be paid even if the merger is not completed.

   In addition, current and prospective employees of InSight may experience
uncertainty about their future roles with the surviving corporation until after
the merger is completed or if the merger is not completed. This may adversely
affect the ability of InSight to attract and retain key management, marketing
and technical personnel.

   Further, if the merger is terminated and the InSight board of directors
determines to seek another merger or business combination, we cannot assure you
that it will be able to find a transaction providing as much stockholder value
as this merger. While the merger agreement is in effect, subject to certain
limited exceptions, we are prohibited from soliciting, initiating or
encouraging or entering into any extraordinary transactions, such as a merger,
sale of assets or other business combination, with any third party.

The financing which is necessary to complete the merger is not assured.

   InSight Holdings' obligation to complete the merger is contingent upon,
among other things, obtaining the financing contemplated in the commitment
letters obtained by it at the time of execution of the merger agreement.
InSight Holdings is not required to obtain alternative financing if these
financing arrangements do not materialize. Accordingly, no alternative
financing arrangements or alternative financing plans have been made by InSight
Holdings. Since the financing for the merger is not assured, we are unable to
assure you that InSight Holdings will be able to obtain the financing required
to complete the merger. If InSight Holdings is unable to obtain the necessary
financing, the merger will not be completed and, as a result, you will remain
an InSight stockholder.

   The terms of this financing are discussed in greater detail on page 29 of
this proxy statement. You are encouraged to read this information carefully.

                              THE SPECIAL MEETING

   We are furnishing this proxy statement to InSight stockholders as part of
the solicitation of proxies by the InSight board of directors for use at the
special meeting.

Date, Time and Place

   The special meeting will be held at                      , at       a.m.,
local time, on         , 2001.

Purpose of the Special Meeting

   At the special meeting, the InSight stockholders will be asked to consider
and vote upon proposals to approve:

  .  the merger agreement, which provides that:

   (a)  JWCH Merger Corp will be merged with and into InSight, with InSight
        surviving the merger; and

   (b)  each issued and outstanding share of InSight common stock will be
        converted into and represent the right to receive $18 in cash; and

  .  any other matters that are properly brought before the InSight special
     meeting or any adjournment or postponement of the meeting.

Record Date; Stockholders Entitled to Vote; Quorum

   Only holders of record of InSight common stock and preferred stock at the
close of business on           , 2001, the record date, are entitled to notice
of and to vote at the special meeting. On the record date,      shares of
InSight common stock (including shares of InSight preferred stock on an as-if-
converted basis) and      shares of InSight Series D preferred stock were
issued and outstanding and held by approximately      and      holders of
record, respectively. A quorum is present at the special meeting for purposes
of the vote of the holders of InSight common stock if a majority of the total
number of shares of outstanding InSight common stock and preferred stock (with
the preferred stock voting on an as-if-converted basis) which are issued and
outstanding and entitled to vote on the record date are represented in person
or by proxy. Shares of InSight common stock represented at the special meeting
but not voting, including abstentions and broker non-votes, will be treated as
present at the special meeting for purposes of determining the presence or
absence of a quorum for the transaction of all business. If a quorum is not
present at the special meeting, it is expected that the meeting will be
adjourned or postponed to solicit additional proxies. Holders of record of
InSight common stock and preferred stock on the record date are entitled to
one vote per share of common stock (with the preferred stock voting on an as-
if-converted basis) at the special meeting.

The Board of Directors Recommendation

   The InSight board of directors has determined that the merger is advisable
and fair to, and in the best interests of, InSight stockholders, has
unanimously approved the merger agreement and the merger, and unanimously
recommends that the InSight stockholders vote FOR adoption of the merger
agreement.

Vote Required

   The approval of the merger agreement will require the affirmative vote of
the holders of a majority of the outstanding shares of InSight common stock
and preferred stock, as of the record date, voting as a single class, with the
holders of InSight preferred stock voting on an as-if-converted basis.

   If you abstain from voting or do not vote, either in person or by proxy, it
will have the effect of a vote against adoption of the merger agreement.

                                      12


Executive Officers and Directors Voting

   On the record date, directors and executive officers of InSight beneficially
owned approximately    % of the outstanding shares of InSight common stock
(assuming the conversion of InSight preferred stock into common stock). Each of
our directors and executive officers has advised us that he or she intends to
vote all shares of InSight capital stock over which he or she has or shares
voting control FOR adoption of the merger agreement.

Voting Agreements

   On June 29, 2001, each of General Electric Company, GE Fund and various
entities affiliated with The Carlyle Group, which collectively beneficially
owned approximately   % of the outstanding InSight common stock (on an as-if-
converted basis) as of the record date, entered into a voting agreement with
InSight Holdings and JWCH Merger Corp. pursuant to which they have agreed,
subject to the terms and conditions of the voting agreement, to vote the shares
of InSight capital stock they beneficially own FOR adoption of the merger
agreement. The voting agreements are attached hereto as Annex III. Each of
General Electric Company, GE Fund and the various entities affiliated with The
Carlyle Group have also granted irrevocable proxies, including a power of
attorney, to InSight Holdings to vote its shares FOR adoption of the merger
agreement. Pursuant to the voting agreements, each of General Electric Company,
GE Fund and the various entities affiliated with The Carlyle Group agreed to
convert the InSight preferred stock they own into InSight Series D preferred
stock prior to the record date, which has been completed. Such stockholders
also agreed to further convert such Series D preferred stock into common stock
prior to the consummation of the merger. The effect of the voting agreements
described above is that the holders of a majority of the shares of InSight
common stock (including the InSight preferred stock voting on an as-if-
converted basis) have agreed to vote for adoption of the merger agreement.

Voting of Proxies

   All shares which are entitled to vote and are represented by properly
executed proxies received prior to or at the special meeting, and not revoked,
will be voted at the special meeting in the manner indicated on the proxies.
Properly executed proxies that do not contain voting instructions will be voted
FOR adoption of the merger agreement.

   Only shares voted for adoption of the merger agreement, including properly
executed proxies that do not contain voting instructions, will be counted as
favorable votes for adoption of the merger agreement. If you abstain from
voting or do not vote, either in person or by proxy, it will count as a vote
against adoption of the merger agreement. Brokers who hold shares of common
stock in street name for customers who are the beneficial owners of such shares
may not give a proxy to vote those customers' shares in the absence of specific
instructions from those customers. Those non-voted shares are referred to as
broker non-votes and count as votes against adoption of the merger agreement.
Thus, if your shares are held in street name and you do not instruct your
broker how to vote your shares, your shares will count as votes against
adoption of the merger agreement.

   We do not expect that any matter other than the proposal to adopt the merger
agreement will be brought before the special meeting. If, however, the InSight
board of directors properly presents other matters, the persons named as
proxies will vote on those other matters in accordance with their judgment. In
addition, the persons named as proxies may propose and vote for one or more
adjournments or postponements of the special meeting, including adjournments or
postponements to permit further solicitation of proxies. No proxy voted against
the proposal to adopt the merger agreement will be voted in favor of any
adjournment or postponement.


                                       13


Revocability of Proxies

   The grant of a proxy on the enclosed form of proxy does not preclude you
from voting in person at the special meeting. You may revoke a proxy at any
time by:

  .  filing with the Secretary of InSight, before the proxy is voted at the
     special meeting, a duly executed written notice of revocation of proxy
     which is dated later than the proxy;

  .  before the proxy is voted at the special meeting, submitting a duly

                                   THE MERGER

   The following discussion summarizes the material terms of the merger. While
we believe that the description covers the material terms of the merger, this
summary may not contain all of the information that is important to you. We
urge stockholders to read this proxy statement, the merger agreement and the
other documents referred to herein carefully for a more complete understanding
of the merger.

General

   The merger will be completed if the required approvals of the InSight
stockholders are obtained and all other conditions contained in the merger
agreement are satisfied or waived. Upon completion of the merger, JWCH Merger
Corp. will be merged with and into InSight. InSight will survive the merger,
becoming a wholly-owned subsidiary of InSight Holdings, and the separate
corporate existence of JWCH Merger Corp. will cease. In the merger, each issued
and outstanding share of InSight common stock will be converted into the right
to receive $18 in cash, without interest. Each outstanding warrant and option
to purchase InSight common stock will be canceled and thereafter represent the
right to receive the excess, if any, of the difference between $18 per share
and the warrant's or option's, as applicable, per share exercise price.

   The merger agreement provides that each share of InSight preferred stock
will be converted into a share of InSight common stock immediately prior to the
completion of the merger. Accordingly, if you hold InSight preferred stock, you
will receive the same per share consideration as the holders of InSight common
stock.

Background to the Merger

   At a meeting of the InSight board of directors on October 10, 2000, in
connection with its review of InSight's business plan, the board discussed
InSight's future prospects and the ongoing consolidation occurring in the
diagnostic imaging industry. The InSight board of directors also discussed
various strategic alternatives, including the public or private sale of equity
securities, obtaining additional debt financing, the sale of InSight and a
merger with a company seeking to expand its healthcare services. In reviewing
these strategic alternatives, the InSight board of directors also considered
the amount of capital necessary for InSight to expand its operations and the
lack of an active public market for InSight common stock.

   On November 14, 2000, the InSight board of directors authorized three
members of the board and InSight's Chief Financial Officer to interview
potential financial advisors to assist InSight in identifying and evaluating
strategic alternatives.

   On December 5, 2000, the InSight board of directors appointed a special
committee of directors, consisting of Frank E. Egger (chairman of the InSight
board of directors), Jerome C. Marcus (the board member designated by General
Electric Company) and W. Robert Dahl (a board member designated by The Carlyle
Group) (or Glenn A. Youngkin (a board member designated by The Carlyle Group),
in the absence of Mr. Dahl), to negotiate an engagement letter with a financial
advisor, evaluate and negotiate proposals or offers involving the purchase or
other acquisition of InSight capital stock or a business combination with
InSight and provide progress reports to the InSight board of directors.

   On February 1, 2001, InSight publicly announced that it had retained UBS
Warburg LLC as its exclusive financial advisor to assist InSight in exploring
strategic alternatives to enhance stockholder value, including through a
merger, sale or recapitalization of InSight.

   Beginning on February 3, 2001, 63 potential buyers, both strategic and
financial, were contacted, including J.W. Childs and Halifax. Forty-two of the
potential buyers (35 financial buyers, including J.W. Childs and Halifax, and
seven strategic buyers) executed confidentiality agreements with InSight.
InSight delivered a confidential information memorandum to each potential buyer
that had executed a confidentiality agreement.

   During February 2001, InSight management held discussions with each of the
potential buyers that had executed a confidentiality agreement concerning
InSight's business, operations and financial condition.

                                       17


   In mid-March 2001, InSight received 13 preliminary indications of interest,
all of which were submitted by financial buyers. Each preliminary indication of
interest proposed a cash merger, with per share purchase prices ranging from
approximately $13 to $23 per share of InSight common stock.

   After consultation with InSight management and UBS Warburg, the InSight
special committee authorized InSight management and UBS Warburg to pursue
discussions with seven of the potential buyers. In reaching its decision, the
InSight special committee considered various factors, including:

  .  the size of the investment funds managed by each of the potential
     buyers;

  .  the reputation of each of the potential buyers;

  .  each potential buyer's ability to finance an acquisition; and

  .  the terms set forth in each preliminary indication of interest,
     including the per share purchase price.

   By March 16, 2001, each of the seven potential buyers were contacted and
informed of the process for conducting due diligence and submitting future
proposals.

   On March 20, 2001, the seven potential buyers began attending management
presentations at InSight and, together with their financial and legal advisors,
commenced due diligence. An eighth potential buyer, a strategic buyer, began
due diligence on April 23, 2001. The preliminary due diligence process ended on
May 4, 2001.

   On May 4, 2001, InSight received revised proposals from two potential
buyers, including a proposal from J.W. Childs and Halifax. The J.W. Childs and
Halifax proposal provided for a purchase price of not less than $17.00 per
share of InSight capital stock. With their proposal, J.W. Childs and Halifax
submitted preliminary financing commitment letters and written comments to the
draft merger agreement prepared by InSight's legal advisors. The J.W. Childs
and Halifax proposal also stated that each group would need to conduct further
due diligence.

   The second proposal was submitted by another financial buyer, but did not
attach financing commitments or contain comments to the draft merger agreement.
The other potential buyers, including the strategic buyer, indicated that they
were no longer interested in pursuing an acquisition of InSight.

   On May 7, 2001, the InSight board of directors met to discuss the terms and
conditions of each proposal. Following discussion, the InSight board of
directors authorized InSight management and UBS Warburg to further negotiate
the terms of the proposals submitted by J.W. Childs and Halifax and the other
potential buyer.

   On May 10 and May 11, 2001, at a meeting of the InSight board of directors,
InSight management and UBS Warburg informed the board that J.W. Childs and
Halifax had revised their proposal to provide for a purchase price of not less
than $18.00 per share of InSight capital stock. UBS Warburg also informed the
InSight board of directors that J.W. Childs and Halifax had indicated that they
would not proceed with a transaction unless InSight agreed to negotiate a
transaction exclusively with J.W. Childs and Halifax for a certain period of
time. After discussion, the InSight board of directors authorized InSight
management and InSight's legal and financial advisors to negotiate the terms of
an exclusivity agreement with J.W. Childs and Halifax.

   From May 10 through May 14, 2001, InSight management and InSight's legal and
financial advisors had numerous conversations with J.W. Childs and Halifax
concerning the exclusivity agreement.

   On May 14, 2001, a meeting of the InSight board of directors was held to
consider the exclusivity agreement proposed by J.W. Childs and Halifax. After
discussion, the InSight board of directors authorized InSight management to
execute the exclusivity agreement, which was executed on May 14, 2001. The
exclusivity agreement provided for, among other things (including limited
expense reimbursement and breakup fee provisions), an obligation to exclusively
negotiate with J.W. Childs and Halifax through June 8, 2001 (with a one week
extension at the option of J.W. Childs and Halifax), except in limited
circumstances. This exclusivity period was subsequently extended through June
29, 2001, as discussed below.

                                       18


   From May 14 through June 29, 2001, J.W. Childs and Halifax and their legal,
accounting, financial and other advisors continued to conduct due diligence.

   At two separate meetings held on May 21, 2001 and June 11, 2001, the InSight
board of directors further evaluated and discussed the J.W. Childs and Halifax
proposal. At these meetings, the InSight board of directors also considered
other strategic alternatives with InSight management and UBS Warburg, including
equity financing alternatives and a recapitalization.

   On May 31, 2001, J.W. Childs and Halifax met with InSight senior management
to discuss their potential involvement in InSight following the closing of the
proposed merger.

   On June 15, 2001, the InSight special committee held a meeting at which
InSight management discussed the progress of negotiations with J.W. Childs and
Halifax on the merger agreement and the status of J.W. Childs' and Halifax's
due diligence. The InSight special committee also discussed J.W. Childs' and
Halifax's request to extend the exclusivity period provided for in the
exclusivity agreement. After discussion, the InSight special committee
authorized the extension of the exclusivity period to June 20, 2001.

   From June 12 through June 15, 2001, representatives of InSight, together
with its legal advisors, held numerous conference calls with J.W. Childs' and
Halifax's legal advisors to discuss and negotiate the terms and conditions of
the merger agreement.

   From June 19 through June 21, 2001, representatives of InSight, J.W. Childs
and Halifax, together with their legal advisors, met in person to discuss and
negotiate the terms and conditions of the merger agreement.

   On June 20, 2001, the InSight board of directors met to consider a second
request by J.W. Childs and Halifax to extend the exclusivity period provided
for in the exclusivity agreement. Following a discussion with management and
its legal advisors as to the status of the negotiations concerning the merger
agreement, the InSight board of directors agreed to extend the exclusivity
period through June 25, 2001.

   On June 25, 2001, the InSight board of directors held a meeting at which
InSight management discussed the status of the negotiation of the merger
agreement and other merger related matters.

   On June 27, 2001, following an update as to the status of the negotiations
concerning the merger agreement by InSight management and InSight's legal
advisors, the InSight special committee authorized InSight management to extend
the exclusivity period provided for in the exclusivity agreement until June 29,
2001.

   From June 24 through June 28, 2001, representatives of InSight and its legal
advisors held numerous conference calls with the legal advisors of J.W. Childs
and Halifax to finalize the terms and conditions of the merger agreement.

   On June 29, 2001, the InSight board of directors held a meeting to discuss
the final terms of the J.W. Childs and Halifax proposal to acquire InSight,
including the terms and conditions of the proposed merger agreement. Prior to
the meeting, each board member received a copy of the proposed merger agreement
and information about the proposed merger and InSight. At the meeting, InSight
management and InSight's legal and financial advisors reviewed various aspects
of the proposed transaction with the board, including:

  .  the reasons for, and financial overview of, the proposed transaction;

  .  the potential benefits and risks of approving the merger agreement and
     consummating the proposed transaction;

  .  the principal terms of the merger agreement;

  .  the future prospects of InSight; and

  .  the principal terms of the voting agreements between the purchasing
     group, General Electric Company, GE Fund and various entities affiliated
     with The Carlyle Group.

                                       19


   In addition, at the meeting, UBS Warburg reviewed with the InSight board of
directors its financial analysis of the merger consideration and rendered to
the InSight board an oral opinion (which opinion was confirmed by delivery of a
written opinion dated the same date) to the effect that, as of that date and
based on and subject to the assumptions made, procedures followed, matters
considered and limitations on the review undertaken described in its written
opinion, the merger consideration was fair, from a financial point of view, to
the holders of InSight common stock.

   Following the presentations, the members of the InSight board of directors
who were elected by the holders of InSight common stock deliberated separately
from the entire board. InSight management and InSight's legal and financial
advisors were available to answer any questions. Following their deliberation,
such members unanimously recommended to the entire InSight board of directors
that the board approve the merger and the merger agreement.

   Following discussion, the entire InSight board of directors determined that
the proposed merger was advisable and unanimously approved the merger, the
merger agreement and the voting agreements, and unanimously resolved to
recommend that the InSight stockholders adopt the merger agreement.

   The merger agreement and the voting agreements were signed by the parties
after the close of business on June 29, 2001 and, prior to the commencement of
trading on Monday, July 2, 2001, InSight issued a press release announcing the
execution of the merger agreement.

Reasons for the Merger

   In reaching its decision to approve the merger agreement and the merger and
to recommend adoption of the merger agreement by the InSight stockholders, the
InSight board of directors consulted with its management, as well as its legal
and financial advisors, and independently considered the proposed merger
agreement and the transactions contemplated by the merger agreement. In
unanimously approving the merger agreement, the InSight board of directors
considered a number of factors, both positive and negative, including, without
limitation, the following:

  .  current industry, market and economic conditions;

  .  InSight's business, financial condition, results of operations, assets,
     management, competitive position, operating performance and prospects;

  .  the fact that on February 1, 2001, InSight publicly announced that it
     had retained UBS Warburg as its financial advisor to assist InSight in
     exploring strategic alternatives to enhance stockholder value, which
     increased InSight's visability to potential buyers or other strategic
     partners;

  .  the fact that 63 potential buyers were contacted in a process designed
     to elicit third-party proposals to enter into a strategic relationship
     with InSight, and that such participants in this process were afforded
     ample opportunity to submit proposals to InSight;

  .  the possibility of strategic alternatives to the merger for enhancing
     long-term stockholder value, including investigating strategic
     transactions with other companies;

  .  the merger consideration;

  .  the market price of InSight common stock over the last several years and
     the potential for an increase or decrease in the market price of InSight
     common stock in the future;

  .  the opinion dated June 29, 2001 of UBS Warburg, InSight's financial
     advisor, as to the fairness, from a financial point of view and as of
     that date, of the merger consideration to be received by the holders of
     InSight common stock, as more fully described below under "Opinion of
     InSight's Financial Advisor;"

  .  the terms and conditions of the merger agreement, including the
     termination fees and the closing conditions;

  .  the impact of the merger on InSight's customers, suppliers and
     employees;

                                       20


  .  the likelihood of the merger being approved by the appropriate
     regulatory authorities;

  .  the likelihood that the merger will be completed;

  .  the risk that, despite InSight's efforts after the merger, InSight may
     lose key personnel; and

  .  the likelihood that InSight Holdings would be able to obtain the
     financing necessary to complete the merger.

   The above discussion of the factors considered by the InSight board of
directors is not intended to be exhaustive. Given the variety and number of
factors considered in connection with its evaluation of the merger, the InSight
board of directors did not assign specific weight to the factors reviewed in
reaching its determination, although certain factors were deemed to be more
important than others.

Opinion of InSight's Financial Advisor

   On June 29, 2001, at a meeting of the InSight board of directors held to
evaluate the proposed merger, UBS Warburg delivered to the InSight board of
directors an oral opinion, which opinion was confirmed by delivery of a written
opinion dated the same date, to the effect that, as of that date and based on
and subject to various assumptions, matters considered and limitations
described in the opinion, the merger consideration was fair, from a financial
point of view, to the holders of InSight common stock.

   The full text of UBS Warburg's opinion describes the assumptions made,
procedures followed, matters considered and limitations on the review
undertaken by UBS Warburg. This opinion is attached as Annex II and is
incorporated into this document by reference. UBS Warburg's opinion is directed
only to the fairness, from a financial point of view, of the merger
consideration and does not address any other aspect of the merger or any
related transaction. The opinion does not address InSight's underlying business
decision to effect the merger or constitute a recommendation to any stockholder
as to how to vote with respect to any matters relating to the proposed merger.
Holders of InSight common stock are encouraged to read this opinion carefully
in its entirety. The summary of UBS Warburg's opinion described below is
qualified in its entirety by reference to the full text of its opinion.

   In arriving at its opinion, UBS Warburg:

  .  reviewed current and historical market prices and trading volumes of
     InSight common stock;

  .  reviewed publicly available business and historical financial
     information relating to InSight;

  .  reviewed internal financial information and other data relating to the
     business and financial prospects of InSight, including estimates and
     financial forecasts prepared by InSight's management, that were provided
     to or discussed with UBS Warburg by InSight and were not publicly
     available;

  .  conducted discussions with members of InSight's senior management;

  .  reviewed publicly available financial and stock market data with respect
     to companies in lines of business UBS Warburg believed to be generally
     comparable to those of InSight;

  .  compared the financial terms of the merger with the publicly available
     financial terms of other transactions which UBS Warburg believed to be
     generally relevant;

  .  reviewed the agreement; and

  .  conducted other financial studies, analyses and investigations, and
     considered other information, as UBS Warburg deemed necessary or
     appropriate.

   In connection with its engagement, UBS Warburg was requested to contact, and
held discussions with, third parties to solicit indications of interest in the
possible acquisition of InSight. In connection with its review, with InSight's
consent, UBS Warburg did not assume any responsibility for independent
verification of any of the information that UBS Warburg was provided or
reviewed for the purpose of its opinion and, with InSight's

                                       21


consent, UBS Warburg relied on that information being complete and accurate in
all material respects. In addition, at InSight's direction, UBS Warburg did not
make any independent evaluation or appraisal of any of the assets or
liabilities, contingent or otherwise, of InSight, and was not furnished with
any evaluation or appraisal. With respect to the financial forecasts and
estimates that it reviewed, UBS Warburg assumed, at InSight's direction, that
they were reasonably prepared on a basis reflecting the best currently
available estimates and judgments of InSight's management as to the future
financial performance of InSight. UBS Warburg's opinion is necessarily based on
economic, monetary, market and other conditions existing, and information
available to UBS Warburg, on the date of its opinion.

   At InSight's direction, UBS Warburg was not asked to, and did not, offer any
opinion as to the terms or obligations of the merger agreement or related
documents, or the form of the merger. In rendering its opinion, UBS Warburg
assumed, at InSight's direction, that each of InSight, InSight Holdings and
JWCH Merger Corp. would comply with all material covenants and agreements set
forth in, and other material terms of, the merger agreement and related
documents and that the merger would be consummated in accordance with its
terms, without waiver, modification or amendment of any material term,
condition or agreement. Except as described above, InSight imposed no other
instructions or limitations on UBS Warburg with respect to the investigations
made or the procedures followed by UBS Warburg in rendering its opinion.

   In connection with rendering its opinion to the InSight board of directors,
UBS Warburg performed a variety of financial and comparative analyses that are
summarized below. The following summary is not a complete description of all of
the analyses performed and factors considered by UBS Warburg in connection with
its opinion. The preparation of a fairness opinion is a complex process
involving subjective judgments and is not necessarily susceptible to partial
analysis or summary description. With respect to the analysis of selected
publicly traded companies and the analysis of selected transactions summarized
below, no company or transaction used as a comparison is either identical or
directly comparable to InSight or the merger. These analyses involve complex
considerations and judgments concerning financial and operating characteristics
and other factors that could affect the public trading or acquisition values of
the companies concerned.

   UBS Warburg believes that its analyses and the summary below 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 UBS Warburg's
analyses and opinion. None of the analyses performed by UBS Warburg was
assigned greater significance by UBS Warburg than any other. UBS Warburg
arrived at its ultimate opinion based on the results of all analyses undertaken
by it and assessed as a whole. UBS Warburg did not draw, in isolation,
conclusions from or with regard to any one factor or method of analysis.

   The estimates of InSight's future performance provided by InSight's
management in or underlying UBS Warburg's analyses are not necessarily
indicative of future results or values, which may be significantly more or less
favorable than those estimates. In performing its analyses, UBS Warburg
considered industry performance, general business and economic conditions and
other matters, many of which are beyond InSight's control. Estimates of the
financial value of companies do not purport to be appraisals or reflect the
prices at which companies actually may be sold.

   The merger consideration was determined through negotiation between InSight
and InSight Holdings and the decision to enter into the merger was solely that
of the InSight board of directors. UBS Warburg's opinion and financial analyses
were only one of many factors considered by the InSight board of directors in
its evaluation of the merger and should not be viewed as determinative of the
views of the InSight board of directors or management with respect to the
merger or the merger consideration.

   The following is a brief summary of the material financial analyses
performed by UBS Warburg and reviewed with the InSight board of directors in
connection with its opinion dated June 29, 2001. The financial analyses
summarized below include information presented in tabular format. In order to
fully understand UBS Warburg's financial analyses, the tables must be read
together with the text of each

                                       22


summary. The tables alone do not constitute a complete description of the
financial analyses. Considering the data in the tables 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 UBS Warburg's financial analyses.

 Selected Companies Analysis

   UBS Warburg compared selected financial information and operating statistics
for InSight with corresponding financial information and operating statistics
of Radiologix, Inc. and HealthSouth Corporation, two selected publicly held
companies in the diagnostic imaging industry. Multiples for the selected
companies were based on closing stock prices on June 28, 2001. Estimated
financial data for the selected companies were based on publicly available
research analysts' estimates. Estimated financial data for InSight were based
on internal estimates of InSight's management.

   UBS Warburg reviewed enterprise values, calculated as equity value, plus
debt, less cash, plus minority interests, as multiples of latest 12 months
revenues, earnings before interest, taxes, depreciation and amortization,
commonly known as EBITDA, earnings before interest, taxes and amortization,
commonly known as EBITA, and earnings before interest and taxes, commonly known
as EBIT. UBS Warburg also reviewed equity values as a multiple of latest 12
months and estimated calendar years 2001 and 2002 net income. In reviewing
InSight's estimated calendar years 2001 and 2002 net income, UBS Warburg
utilized internal estimates of InSight's management based on two scenarios, one
which takes into account potential start-up ventures and center acquisitions
that may be undertaken by InSight (referred to as the management plan with
acquisitions), and one which does not give effect to potential start-up
ventures and center acquisitions (referred to as the management plan without
acquisitions). UBS Warburg did not consider separately the results for each of
the two scenarios, but rather considered the results of this analysis taken as
a whole. UBS Warburg then compared the multiples derived from the selected
companies with corresponding multiples for InSight based on the merger

losses have been designated below as "nm." This analysis indicated the

Health Images, Inc.                  MedAlliance, Inc.


   Except in the case of the transaction involving Kohlberg Kravis Roberts &
Co., Ltd. and Alliance Imaging, Inc., UBS Warburg reviewed enterprise values as
multiples of latest 12 months revenues, EBITDA, EBITA and EBIT, and equity
values as a multiple of latest 12 months net income. In the case of the
transaction involving Kohlberg Kravis Roberts & Co., Ltd. and Alliance Imaging,
Inc., UBS Warburg reviewed the enterprise value of Alliance Imaging, Inc. as
multiples of second quarter annualized revenues, EBITDA, EBITA and EBIT, and
its equity value as a multiple of second quarter annualized net income in order
to reflect the financial statistics of Alliance Imaging, Inc. after giving
effect to an acquisition which it consummated prior to the closing of its
transaction with Kohlberg Kravis Roberts & Co., Ltd. UBS Warburg then compared
the implied multiples derived from the selected transactions with InSight's
latest 12 months multiples based on the merger consideration. All multiples
were based on publicly available information at the time of announcement of the
relevant transaction. This analysis indicated the following implied low, mean,
median and high enterprise and equity value multiples for the selected
transactions, as compared to the multiples implied for InSight based on the
merger consideration:

 Premiums Paid Analysis

   UBS Warburg reviewed the premiums paid in six selected transactions in the
diagnostic imaging industry. UBS Warburg reviewed the purchase prices paid in
the selected transactions relative to the target company's closing stock prices
one day, one week, one month and three months prior to public announcement of
the transaction. UBS Warburg also reviewed the purchase prices paid in the
selected transactions relative to the target company's average closing stock
prices one week, one month and three months prior to public announcement of the
transaction. UBS Warburg then compared the premiums implied in the selected
transactions over these specified periods with the premiums implied in the
merger based on the merger consideration and the closing prices of InSight
common stock one week, one month and three months, and the

                                       24


average closing prices of InSight common stock one month and three months,
prior to February 1, 2001 (the date on which InSight publicly announced that it
was evaluating strategic alternatives) and June 29, 2001 (the last trading day
prior to public announcement of the merger). This analysis indicated the
following implied low, mean, median and high premiums in the selected
transactions, as compared to the premiums implied in the merger:

   UBS Warburg also reviewed the premiums paid in 14 selected public to private
transactions and 38 public cash transactions announced between April 1, 2000
and June 28, 2001 with transaction values of greater than $250 million. UBS
Warburg reviewed the purchase prices paid in the selected transactions relative
to the target company's closing stock prices one day, one week and one month
prior to public announcement of the transaction. UBS Warburg also reviewed the
purchase prices paid in the selected transactions relative to the target
company's average closing stock prices one week and one month prior to public
announcement of the transaction. UBS Warburg then compared the premiums implied
in the selected transactions over these specified periods with the premiums
implied in the merger based on the merger consideration and the closing prices
of InSight common stock one day, one week and one month, and the average
closing prices of InSight common stock one week and one month, prior to
February 1, 2001 and June 29, 2001. This analysis indicated the following

 Discounted Cash Flow Analysis

   UBS Warburg performed a discounted cash flow analysis to estimate the
present value of the unlevered, after-tax free cash flows that InSight could
generate over estimated calendar years 2002 through 2006 based both on the
management plan with acquisitions and the management plan without acquisitions.
UBS Warburg calculated a range of estimated terminal values for InSight by
applying terminal value multiples of 3.5x to 5.0x to InSight's estimated
calendar year 2006 EBITDA. The cash flows and terminal values were then
discounted

                                       25


to present value using discount rates ranging from 16.0% to 20.0% in the case
of the management plan with acquisitions and 12.0% to 16.0% in the case of the
management plan without acquisitions. This analysis indicated an implied equity
reference range for InSight of approximately $12.07 to $37.92 per share in the
case of the management plan with acquisitions and approximately $11.62 to
$25.97 per share in the case of the management plan without acquisitions, as
compared to the merger consideration of $18.00 per share. UBS Warburg did not
consider separately the results for each of the two scenarios, but rather
considered the results of this analysis taken as a whole.

   UBS Warburg also performed a sensitivity analysis with respect to its
discounted cash flow analysis utilizing adjustments to the management plan with
acquisitions and the management plan without acquisitions to reflect the
potential for reduced revenue growth, increased general and administrative
expense as a percentage of sales and, in the case of the management plan with
acquisitions, an increased EBITDA multiple relating to center acquisitions. For
purposes of this analysis, UBS Warburg applied to InSight's estimated 2006
EBITDA a terminal value multiple of 4.5x in the case of both the management
plan with acquisitions and the management plan without acquisitions, and
discount rates of 18.0% in the case of the management plan with acquisitions
and 14% in the case of the management plan without acquisitions. This analysis
indicated a potential decrease in the per share value implied in the discounted
cash flow analysis based on the management plan with acquisitions of
approximately $10.44 per share in the case of revenue, $1.33 per share in the
case of general and administrative expenses as a percentage of sales, $1.77 per
share in the case of center acquisitions and $13.31 per share in the case of
all three factors combined. This analysis also indicated a potential decrease
in the per share value implied in the discounted cash flow analysis based on
the management plan without acquisitions of approximately $4.44 per share in
the case of revenue, $0.61 per share in the case of general and administrative
expenses as a percentage of sales and $4.98 per share in the case of the two
factors combined.

 Other Factors

   In rendering its opinion, UBS Warburg also reviewed and considered other
factors, including:

  .  the historical price performance and trading volumes for InSight common
     stock; and

  .  the relationship between movements in InSight common stock, movements in
     the common stock of selected companies in the diagnostic imaging
     industry and movements in both the NASDAQ and Standard and Poors 500
     Index.

 Miscellaneous

   Under the terms of its engagement, InSight has agreed to pay UBS Warburg for
its financial advisory services upon completion of the merger an aggregate fee
based on a percentage of the total consideration, including liabilities
assumed, payable in the merger. The aggregate fee payable to UBS Warburg is
currently estimated to be approximately $2.8 million. InSight also has agreed
to reimburse UBS Warburg for expenses reasonably incurred by UBS Warburg in
performing its services, including fees and expenses of its legal counsel, and
to indemnify UBS Warburg and related persons against liabilities, including
liabilities under the federal securities laws, arising out of its engagement.
UBS Warburg and its affiliates in the past have provided, and currently are
providing, services to J.W. Childs Associates, L.P. unrelated to the proposed
merger, for which services UBS Warburg and its affiliates have received and
will receive customary compensation. UBS Warburg also may participate in the
financing of the merger and in that event would receive customary compensation
in connection with such financing.

   InSight selected UBS Warburg as its exclusive financial advisor in
connection with the merger because UBS Warburg is an internationally recognized
investment banking firm with substantial experience in similar transactions.
UBS Warburg is continually engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, leveraged buyouts,
negotiated underwritings, competitive bids, secondary distributions of listed
and unlisted securities and private placements.

                                       26


   In the ordinary course of business, UBS Warburg, its successors and
affiliates may actively trade the securities of InSight and affiliates of
InSight Holdings for their own accounts and the accounts of their customers
and, accordingly, may at any time hold a long or short position in these
securities.

Interests of InSight's Directors and Executive Officers in the Merger

   In considering the recommendation of the InSight board of directors in favor
of the merger and the merger agreement, you should be aware that certain
directors and executive officers of InSight have interests in the merger that
are different from, or in addition to, the interests of InSight stockholders.
These interests relate to or arise from, among other things:

  .  the continued indemnification of current directors and officers of
     InSight pursuant to the merger agreement;

  .  the retention of certain executive officers of InSight as employees or
     consultants after the merger is completed pursuant to new employment
     agreements which, in some cases, provide for increased benefits,
     including stock options in InSight Holdings;

  .  options and warrants held by InSight's directors, executive officers and
     employees will become fully vested as a result of the merger;

  .  certain officers of InSight are parties to employment agreements that
     provide for severance payments following a "change in control," such as
     the merger, if such officers terminate his or her employment with
     InSight; and

  .  the affiliation of certain of our directors with InSight's major
     stockholders.

   These interests are described below, and except as described below, those
persons have, to the knowledge of InSight, no material interest in the merger
apart from those of InSight stockholders generally. The InSight board of
directors was aware of, and considered the interests of its employees in
approving the merger agreement and the merger.

   Indemnification and Insurance. The merger agreement provides that all rights
of indemnification from liabilities existing in favor of the current and former
directors or officers of InSight and its subsidiaries as provided in InSight's
certificate of incorporation and bylaws and certain indemnification agreements
of InSight will be assumed by the surviving corporation in the merger, and will
continue in full force and effect in accordance with their terms after the
merger. InSight Holdings has also agreed to cause the surviving corporation to
maintain, for six years after the merger, directors' and officers' liability
insurance for acts or omissions which occur prior to the merger for those
directors and officers who were, as of the date of the merger agreement,
covered by the InSight's directors' and officers' liability insurance policy,
on terms no less advantageous than those in effect on the date of the merger
agreement. InSight Holdings' obligation to provide this insurance coverage is
subject to a cap of 175% of the current annual premium paid by InSight for its
existing insurance coverage. If InSight Holdings cannot maintain the existing
or equivalent insurance coverage without exceeding the 175% cap, InSight
Holdings is required to obtain only that amount of insurance coverage which can
be obtained by paying an annual premium equal to the 175% cap.

   Our Executive Officers. Most of InSight's current executive officers are
expected to be retained as employees of or consultants to the surviving
corporation after the merger. Upon the closing of the merger, it is expected
that Steven T. Plochocki, who is currently President and Chief Executive
Officer of InSight; Patricia R. Blank, who is currently Executive Vice
President and Chief Information Officer of InSight; Michael A. Boylan, who is
currently Executive Vice President, Operations, Eastern Division of InSight;
Thomas V. Croal, who is currently Executive Vice President and Chief Financial
Officer of InSight; Michael S. Madler, who is currently Executive Vice
President, Operations, Western Division of InSight; Brian G. Drazba, who is
currently Senior Vice President--Finance and Controller of InSight; and Cecilia
A. Guastaferro, who is currently Senior Vice President--Human Resources of
InSight, will each serve in their current capacities with the surviving
corporation.

                                       27


   Each of the individuals listed above have entered into a new employment
agreement which will be effective upon the closing of the merger. Except for
Mr. Plochocki's agreement, which has a term of three years, each of the
employment agreements provides for rolling twelve month terms. The employment
agreements provide for substantial benefits, including the following:

  .  a determined annual salary which is subject to annual review by the
     InSight board of directors;

  .  a discretionary bonus, the amount of which, depending upon the
     executive, is (a) based upon the recommendation of InSight's President
     and Chief Executive Officer, or (b) a percentage of the employee's base
     salary and contingent upon InSight attaining certain performance goals;

  .  the maintenance of a life insurance policy in an amount equal to three
     times the amount of the executive's base salary and other benefits
     generally offered by InSight;

  .  in the case of Mr. Plochocki, twenty-four months or, in the case of all
     other officers, twelve months of severance payments and the continued
     participation in InSight's medical and other benefit plans upon the
     termination of executive's employment by (a) InSight without cause or
     (b) in some cases, the executive for good reason; and

  .  the grant of an option to purchase shares of common stock of InSight
     Holdings.

   In addition, each of InSight's executive officers and certain other officers
are parties to employment agreements that provide for severance payments to
such individuals if such individuals terminate their employment with the
surviving corporation following a change in control. The amount of severance
payment is one or two years base salary depending upon the employee. In
connection with executing the new employment agreements discussed in the
previous paragraph, thirteen of the 16 officers have agreed to forego the right
to receive any severance payment, including Messrs. Plochocki, Boylan, Croal,
Madler and Drazba and Ms. Blank and Ms. Guastaferro. In addition,
Messrs. Plochocki, Boylan, Croal and Madler have entered into stock option
agreements, which are effective upon the closing of the merger, pursuant to
which they have agreed to cancel certain of their options to purchase InSight
common stock in exchange for receiving fully vested options to purchase an
equivalent number of shares of common stock of InSight Holdings.

   Employee Benefits. InSight Holdings has agreed to provide InSight employees
with substantially similar benefits currently available to them. With respect
to each benefit in which InSight employees subsequently participate, for
purposes of determining vesting and entitlement to benefits, including for
severance benefits and vacation entitlement, service with InSight will be
treated as service with the surviving corporation. This service will also apply
for purposes of satisfying any waiting periods, evidence of insurability
requirements, or the application of any pre-existing condition limitations.
Each benefit plan of the surviving corporation will waive pre-existing
condition limitations to the extent waived under the applicable InSight benefit
plan. InSight's employees will receive credit under each surviving corporation
benefit plan for amounts paid under a corresponding InSight benefit plan during
the same benefit period for purposes of applying deductibles, co-payments and
out-of-pocket maximums.

   Stock Options and Warrants. The merger agreement provides that holders of
InSight stock options and warrants, whether or not then exercisable, will
receive a cash payment for each option or warrant in an amount equal to the
difference between the exercise price of the option or warrant and the per
share consideration received by InSight stockholders in connection with the
merger.

   In addition, the executive officers of InSight will be granted options to
purchase the common stock of InSight Holdings. The number of options that will
be awarded to each individual will be determined at the effective time of the
merger and will depend, in part, on the capital structure of InSight Holdings.
The total number of options to be awarded to InSight management upon the
closing of the merger will equal approximately 10% of the issued and
outstanding shares of capital stock of InSight Holdings.

   Director Affiliation. Certain members of the InSight board of directors
serve as the nominees of General Electric Company and The Carlyle Group, which
collectively beneficially own approximately    % of the

                                       28


outstanding shares of InSight common stock as of the record date. In addition,
GE Capital Equity Holdings, Inc., an affiliate of General Electric Company, has
invested a total of $10 million in the $200 million private equity fund managed
by Halifax.

Accounting Treatment

   The merger will be accounted for under the "purchase" method of accounting
in accordance with generally accepted accounting principles.

Determination of the Merger Consideration

   The merger consideration was determined through arm's-length negotiations
between InSight, J.W. Childs and Halifax.

Financing

   InSight Holdings' and JWCH Merger Corp.'s obligation to complete the merger
is contingent upon, among other things, obtaining the financing for the merger
contemplated by commitment letters obtained by it at the time of execution of
the merger agreement. The consummation of the merger will require InSight
Holdings to make payments to:

  .  the holders of InSight common stock (including holders of InSight
     preferred stock on an as-if-converted basis), in the amount of $18 per
     share, in cash;

  .  the holders of InSight options, in an amount equal to the net value in
     the options;

  .  the holders of InSight warrants, in an amount equal to the net value in
     the warrants;

  .  the holders of certain of our existing indebtedness, which will be
     refinanced or retired in connection with the merger; and

  .  those who are owed fees and expenses relating to the merger and the
     financing.

   InSight and InSight Holdings estimate that the total amount of funds
necessary to complete the merger and related transactions is approximately $475
million. These funds are currently expected to come from the following sources:

  .  an equity investment by J.W. Childs Equity Partners II, L.P. and Halifax
     Capital Partners, L.P. of up to $81.5 million, net of the value of the
     stock options rolled over by certain executive officers of InSight, and
     $20 million, respectively, as more fully described below under "--Equity
     Contribution;"

  .  borrowings by InSight in an aggregate amount of up to $150 million under
     a $275 million senior credit facility, as more fully described below
     under "--Senior Secured Credit Facility;"

  .  the issuance of $200 million of unsecured senior subordinated notes to
     be issued by JWCH Merger Corp. (which will become obligations of InSight
     upon consummation of the merger of JWCH Merger Corp. with and into
     InSight), as more fully described below under "--Senior Subordinated
     Notes;" and

  .  cash balances of InSight at the closing of the merger which will include
     option and warrant proceeds.

   InSight Holdings is not required to obtain alternative financing if the
financing arrangements listed above do not materialize. Accordingly, no
alternative financing arrangements or alternative financing plans have been
made by InSight Holdings. If the merger is completed, InSight and InSight
Holdings expect that these debt obligations will be repaid through cash flow
generated from operations in the ordinary course of business and/or through
refinancing.

   The documentation governing the senior credit facility and the senior
subordinated notes has not yet been finalized and, accordingly, remains subject
to change.

                                       29


   Equity Contribution. A portion of the funds required to close the merger
will be provided by a cash investment in InSight Holdings of up to
approximately $101.5 million by J.W. Childs and Halifax, of which J.W. Childs
shall be obligated to invest up to $81.5 million, net of the value of the stock
options rolled over by certain executive officers of InSight, and Halifax shall
be obligated to invest up to $20 million. J.W. Childs and Halifax are not
obligated to provide the equity financing unless all of the conditions to
closing under the merger agreement for the benefit of InSight Holdings are
satisfied. InSight is a third party beneficiary of the equity commitments of
J.W. Childs and Halifax.

   Senior Secured Credit Facility. InSight will obtain a senior credit facility
from a syndicate of financial institutions arranged by Banc of America
Securities LLC (in consultation with J.W. Childs and Halifax) in an aggregate
amount of up to $275 million, of which up to $150 million will be available on
the closing date. The senior credit facility documentation will contain
customary representations and warranties by InSight. The commitment to provide
the senior credit facility is subject to the satisfaction of customary
conditions and covenants, including the accuracy in all material respects of
InSight's representations and warranties. The following is a summary of certain
of the material conditions to be satisfied in order for InSight to obtain
borrowings under the senior credit facility:

  .  all of the representations and warranties in the loan documentation
     shall be materially correct;

  .  no defaults or events of default shall have occurred and be continuing;

  .  the absence of any material misstatements in, or omissions from, the
     materials that have been or are being furnished to Bank of America for
     its review in connection with the merger;

  .  the completion of the equity contributions described under "--Equity
     Contribution" above in the amount of at least $100 million and the
     completion of senior subordinated debt financing in the amount of $200
     million;

  .  the receipt of certification of the financial condition and solvency of
     InSight and InSight Holdings;

  .  the receipt of the documentation in connection with the merger and the
     related transactions in form and substance satisfactory to Bank of
     America and the receipt of evidence satisfactory to Bank of America that
     the merger has been completed in accordance with the terms of the merger
     agreement;

  .  the absence of any material adverse change in the assets, business or
     financial condition of InSight since June 30, 2000;

  .  receipt by Bank of America of satisfactory opinions of counsel;

  .  receipt of all governmental, stockholder and third-party consents and
     approvals related to the merger;

  .  the absence of any litigation that could reasonably be expected to have
     a material adverse effect on InSight;

  .  InSight shall be in compliance with certain financial ratios;

  .  the absence of any material changes or disruptions in the syndication,
     financial or capital markets that could materially impair the
     syndication of the senior credit facility;

  .  Bank of America shall have received audited financial statements for
     InSight for its fiscal year ended June 30, 2001;

  .  the satisfaction of Bank of America with the capitalization and
     ownership structure of InSight and InSight Holdings;

  .  the negotiation, execution and delivery of definitive financing
     agreements satisfactory to Bank of America; and

  .  all fees and expenses owed to Bank of America related to the senior
     credit facility have been paid in full.

                                       30


   Borrowings under the senior credit facility will be secured by a perfected
first priority security interest in all assets of InSight Holdings, InSight as
the surviving corporation, and InSight's subsidiaries, including accounts and
notes receivable, inventory, equipment, owned real property, licenses, stock of
subsidiaries and intangible assets, in each case subject to exceptions to be
agreed upon. InSight Holdings and InSight's subsidiaries will provide
guarantees of the borrowings under the senior credit facility, subject to
exceptions to be agreed upon.

   Senior Subordinated Notes.  JWCH Merger Corp. is expected to issue $200
million of senior subordinated notes. Upon consummation of the merger, the
senior subordinated notes will become obligations of InSight. It is anticipated
that the senior subordinated notes will have the following features:

  .  a maturity of 10 years from the issue date;

  .  be unsecured obligations and rank equally with all unsecured senior
     subordinated indebtedness of JWCH Merger Corp. (and, following the
     consummation of the merger, InSight);

  .  interest will be paid in cash, semi-annually;

  .  be subordinated to any senior indebtedness of JWCH Merger Corp. (and,
     following the consummation of the merger, InSight), including the senior
     secured credit facilities; and

  .  be guaranteed by InSight Holdings and the subsidiaries of InSight which
     guarantee the senior secured credit facilities.

   InSight expects that the senior subordinated notes also will contain
covenants that are customary for this type of financing, including, without
limitation, restrictions on payments and investments, liens, indebtedness,
affiliate transactions, asset sales and mergers. Banc of America Securities LLC
and Banc of America Bridge LLC have committed to arrange the sale of up to $200
million senior subordinated notes.

   The closing of the senior subordinated debt financing will be subject to the
satisfaction of customary conditions precedent, including, among others, the
following:

  .  the execution, delivery and performance of the documentation relating to
     the senior subordinated debt financing will not conflict with or
     constitute a default under or violate (a) the certificate of
     incorporation or bylaws of InSight or InSight Holdings, (b) any material
     agreement of InSight or InSight Holdings, (c) any laws, or (d) any
     decree or ruling of a governmental authority, where such conflict or
     default has a material adverse effect on InSight or InSight Holdings;

  .  receipt of satisfactory opinions of counsel;

  .  preparation of an offering memorandum and assistance in the marketing of
     the senior subordinated notes;

  .  satisfactory evidence that InSight and InSight Holdings shall have
     sufficient cash on hand at the consummation of the senior subordinated
     note offering to meet InSight's ongoing financial needs; and

  .  the aggregate amount of funded debt, excluding borrowings under the
     senior secured credit facility and the senior subordinated notes, does
     not exceed $12 million.

   In addition to the above conditions, the closing of the senior subordinated
debt financing will be subject to the satisfaction of other customary
conditions precedent that are substantially the same as the conditions
precedent for the senior secured credit facilities, which are described above
under the heading "Senior Secured Credit Facility."

                                       31


Payment for Shares

   A bank or trust company designated by InSight Holdings and reasonably
acceptable to InSight will act as the paying agent for the payment of the
merger consideration. At the consummation of the merger, InSight Holdings will
deposit, or cause to be deposited, sufficient cash with the paying agent in
order to permit the payment of the merger consideration.

   Instructions with regard to the surrender of certificates formerly
representing shares of InSight capital stock, together with the letter of
transmittal to be used for that purpose, will be mailed to you as soon as
practicable after the effective time of the merger. You should not surrender
certificates until you receive the letter of transmittal. As soon as
practicable following the receipt by the paying agent of your certificate(s)
formerly representing InSight capital stock, a duly completed and validly
executed letter of transmittal and any other item specified by the letter of
transmittal, the paying agent will pay such amount equal to the product of the
merger consideration multiplied by the number of shares of capital stock
represented by such certificate(s) to such stockholder by check, wire transfer
or draft less any amount required to be withheld under applicable tax
regulations, if applicable. All certificates formerly representing InSight
capital stock will be canceled.

   After the completion of the merger, holders of certificates formerly
representing InSight capital stock will cease to have any rights as
stockholders of InSight, except as provided in the merger agreement, and such
holders' sole right will be to receive the merger consideration with respect to
such shares. The surviving corporation shall pay all service charges, brokerage
commissions and transfer taxes in connection with the stockholders' surrender
of their shares of InSight capital stock in exchange for cash, except if
payment is to be made to a person other than the person in whose name the
surrendered certificate is registered. In such case, it will be a condition of
payment that the person requesting such payment pay any transfer and other
taxes required by reason of such payment or establish to the satisfaction of
the surviving corporation and the paying agent that such taxes have been paid
or are not applicable. At the effective time of the merger, InSight's stock
transfer books will be closed and there will not be any registration of
transfers of shares of InSight capital stock thereafter on the records of
InSight.

   To the extent permitted by law, the appointment of the paying agent will be
terminated 180 days following the consummation of the merger. Any portion of
the merger consideration remaining undistributed upon termination of the paying
agent's appointment will be returned to InSight Holdings, and any holders of
certificates formerly representing shares of InSight capital stock may
thereafter surrender to InSight Holdings such certificates and (subject to
abandoned property, escheat or similar laws) receive in exchange therefor
the merger consideration to which they are entitled, but shall have no greater
rights against InSight Holdings than may be accorded to general creditors of
InSight Holdings under relevant law. In no event will former holders of shares
of InSight capital stock be entitled to receive payment of any interest on the
merger consideration.

Effective Time of the Merger

   The merger will become effective upon the filing of a certificate of merger
with the Secretary of State of the State of Delaware, or at such later time as
stated in the certificate of merger or agreed upon by InSight, InSight Holdings
and JWCH Merger Corp. The filing of the certificate of merger will occur at the
time of the closing of the merger.

Delisting and Deregistration of InSight Common Stock

   If the merger is completed, InSight common stock will be delisted from the
Nasdaq Small Cap Market and will be deregistered under the Securities Exchange
Act of 1934.

Certain Material United States Federal Income Tax Consequences of the Merger

   The following discussion is a summary of the material United States federal
income tax consequences of the merger to stockholders whose shares of InSight
common stock are surrendered pursuant to the merger,

                                       32


including the federal income tax consequences of the receipt of any cash
amounts by dissenting stockholders pursuant to the exercise of appraisal
rights. It is based on and subject to the Internal Revenue Code of 1986, as
amended (the "Code"), the regulations promulgated under the Code, existing
administrative interpretations and court decisions as in effect on the date
hereof, all of which are subject to change, possibly with a retroactive effect.

   The discussion does not address all aspects of United States federal income
taxation and may not apply to shares of InSight common stock received pursuant
to the exercise of employee stock options or otherwise as compensation or to
stockholders who have special treatment under the federal income tax laws,
including, without limitation, stockholders that are non-U.S. persons, life
insurance companies, tax-exempt organizations, financial institutions, dealers
in securities, persons who have a functional currency other than the United
States dollar, or stockholders holding shares as part of a straddle, a
conversion transaction, a hedging transaction or other similar transaction.
This discussion assumes you hold our shares of common stock as capital assets
within the meaning of section 1221 of the Code.

   The receipt of cash payments pursuant to the merger, including any cash
amounts received by dissenting stockholders pursuant to the exercise of their
appraisal rights, will be a taxable transaction for federal income tax
purposes. In general, for federal income tax purposes, a stockholder will
recognize capital gain or loss equal to the difference between the cash
received by the stockholder pursuant to the merger agreement and the
stockholder's adjusted tax basis in the shares of InSight common stock
surrendered pursuant to the merger agreement. Gain or loss will be calculated
separately for each block of shares of InSight common stock surrendered in the
merger.

   If a non-corporate stockholder's holding period for the shares of InSight
common stock exceeds one year at the time the merger is completed, either a 20%
or a 10% capital gains rate generally will apply to the gain, depending on the
amount of taxable income of the stockholder for such year. If the stockholder's
holding period for the shares of InSight common stock is one year or less, the
gain will be taxed at the same rates as ordinary income. Capital gains of
corporate stockholders are generally taxable at the regular tax rates
applicable to corporations. The deductibility of capital losses is subject to
certain limitations.

   InSight Holdings or its payment agent will be required to withhold up to 31%
of the gross proceeds payable to a stockholder in the merger unless (i) an
exemption applies under applicable law and regulations, or (ii) the stockholder
provides, in a properly completed substitute Form W-9, the stockholder's
taxpayer identification number and certifies under penalties of perjury that
such number is correct and that the stockholder is not subject to backup
withholding. Therefore, unless such an exemption exists and is demonstrated in
a manner satisfactory to InSight Holdings or its payment agent in accordance
with the instructions that will accompany the substitute Form W-9, each
stockholder should complete and sign the substitute Form W-9 that will be made
available to the stockholder with the letter of transmittal, so as to provide
the information and certification necessary to avoid backup withholding.

   Backup withholding is not an additional tax but, rather, is a method of tax
collection. Stockholders will be entitled to credit any amounts withheld under
the backup withholding rules against their actual tax liabilities provided the
required information is furnished to the Internal Revenue Service.

   The foregoing is a general discussion of the material United States federal
income tax consequences of the merger and is included for general information
only. The foregoing discussion does not take into account the particular facts
and circumstances of your status and attributes. As a result, the United States
federal income tax consequences addressed in the foregoing discussion may not
apply to you. In view of the individual nature of income tax consequences, you
are urged to consult your tax advisor to determine the specific tax
consequences of the merger to you, including the application and effect of
United States federal, state, local and other tax laws and the possible effects
of changes in the United States federal and other tax laws.

                                       33


Regulatory Matters

   Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and related
rules, certain transactions, including the merger, may not be completed unless
certain waiting period requirements have been satisfied. InSight and InSight
Holdings filed a pre-merger notification and report form with the Antitrust
Division of the Department of Justice and the Federal Trade Commission on July
6, 2001 and        , 2001, respectively. The applicable waiting period expires
on        , 2001. At any time before or after the effective time of the merger,
the Antitrust Division of the Department of Justice, the Federal Trade
Commission or others could take action under the antitrust laws, including
seeking to prevent the merger, to rescind the merger or to conditionally
approve the merger upon the divestiture of substantial assets of InSight or
InSight Holdings. Although no challenge to the merger is anticipated, there can
be no assurance that a challenge to the merger on antitrust grounds will not be
made or, if made, that it would not be successful.

Appraisal Rights

   If the merger is consummated, a holder of record of shares of our capital
stock who objects to the terms of the merger may seek an appraisal under
Section 262 of the Delaware General Corporation Law of the "fair value" of such
holder's shares. The following is a summary of the principal provisions of
Section 262 and does not purport to be a complete description. A copy of
Section 262 is attached to this proxy statement as Annex IV. Due to the
complexity of the procedures for exercising the right to seek appraisal of
InSight capital stock, InSight stockholders who are considering exercising such
appraisal rights should seek the advice of counsel, but InSight will not be
responsible for the cost of retaining such counsel. Failure to take any action
required by Section 262 will result in a termination or waiver of a
stockholder's rights under Section 262.

   A stockholder electing to exercise appraisal rights must (a) deliver to us,
before our stockholders vote on the merger agreement, a written demand for
appraisal that is made by or on behalf of the person who is the holder of
record of our capital stock for which appraisal is demanded and (b) not vote in
favor of adopting the merger agreement. The demand must be delivered to us at
4400 MacArthur Blvd., Suite 800, Newport Beach, California 92660, Attn:
Secretary. A proxy or vote against adopting the merger agreement does not
constitute a demand. A stockholder electing to take this action must do so by a
separate written demand that reasonably informs us of the identity of the
holder of record and of the stockholder's intention to demand appraisal of the
holder's shares of our capital stock. Because a proxy left blank will, unless
revoked, be voted FOR adoption of the merger agreement, a stockholder electing
to exercise appraisal rights who votes by proxy must not leave the proxy blank
but must vote AGAINST adoption of the merger agreement or ABSTAIN from voting
for or against adoption of the merger agreement.

   Only holders of record of our capital stock are entitled to demand appraisal
rights for their shares of our capital stock registered in their name. The
demand must be executed by or for the holder of record, fully and correctly, as
the holder's name appears on the holder's stock certificates. If our capital
stock is owned of record in a fiduciary capacity, such as by a trustee,
guardian or custodian, the demand should be executed in that capacity. If our
capital stock is owned of record by more than one person, as in a joint tenancy
or tenancy in common, the demand should be executed by or for all owners. An
authorized agent, including one of two or more joint owners, may execute the
demand for appraisal for a holder of record; however, the agent must identify
the owner or owners of record and expressly disclose the fact that, in
executing the demand, the agent is acting as agent for the owner or owners of
record.

   A holder of record, such as a broker, who holds shares of our capital stock
as nominee for beneficial owners may exercise a holder's right of appraisal
with respect to shares of our capital stock held for all or less than all of
the beneficial owners. In that case, the written demand should set forth the
number of shares of our capital stock covered by the demand. Where no number of
shares is expressly mentioned, the demand will be presumed to cover all shares
of our capital stock standing in the name of the holder of record. Stockholders
who hold their shares in brokerage accounts or other nominee forms and who wish
to exercise appraisal rights are urged to consult with their brokers to
determine appropriate procedures for making a demand for appraisal rights by
the broker or the nominee.

                                       34


   Within 10 days after the filing of the certificate of merger with the
Delaware Secretary of State, we will send notice of the effectiveness of the
merger to each person who prior to that time satisfied the foregoing
conditions.

   Within 120 days after the filing of the certificate of merger with the
Delaware Secretary of State, we or any stockholder who has satisfied the
foregoing conditions may file a petition in the Delaware Court of Chancery
demanding a determination of the fair value of our capital stock. Stockholders
seeking to exercise appraisal rights should not assume that we will file a
petition to appraise the value of their shares of our capital stock or that we
will initiate any negotiations with respect to the "fair value" of such capital
stock. Accordingly, holders of our capital stock should initiate all necessary
action to perfect their appraisal rights within the time periods prescribed in
Section 262.

   Within 120 days after the filing of the certificate of merger with the
Delaware Secretary of State, any stockholder who has complied with the
requirements for exercise of appraisal rights, as discussed above, is entitled,
upon written request, to receive from us a statement setting forth the
aggregate number of shares of our capital stock not voted in favor of the
merger and with respect to which demands for appraisal have been made and the
aggregate number of holders of that capital stock. We are required to mail such
statement within 10 days after we receive a written request to do so or within
10 days after expiration of the period for delivery of demands for appraisals
under Section 262, whichever is later.

   If a petition for an appraisal is timely filed, after a hearing on the
petition, the Delaware Court of Chancery will determine the stockholders
entitled to appraisal rights and will appraise our capital stock owned by such
stockholders, determining its "fair value" exclusive of any element of value
arising from the accomplishment or expectation of the merger and will determine
the amount of interest, if any, to be paid upon the value of our capital stock
of the stockholders entitled to appraisal. Any such judicial determination of
the "fair value" of our capital stock could be based upon considerations other
than or in addition to the price paid in the merger and the market value of our
capital stock, including asset values, the investment value of InSight common
stock and any other valuation considerations generally accepted in the
investment community. The value so determined for our capital stock could be
more than, less than or the same as the consideration paid pursuant to the
merger agreement. Upon application of a stockholder, the court may also order
that all or a portion of any stockholder's expenses incurred in connection with
an appraisal proceeding, including, without limitation, reasonable attorneys'
fees and fees and expenses of experts utilized in the appraisal proceeding, be
charged pro rata against the value of all shares of our capital stock entitled
to appraisal.

   Any stockholder who has duly demanded an appraisal in compliance with
Section 262 will not, after the filing of the certificate of merger with the
Delaware Secretary of State, be entitled to vote the shares subject to such
demand for any purpose or be entitled to dividends or other distributions on
those shares of our capital stock, other than those payable or deemed to be
payable to stockholders of record as of a date prior to the filing of the
certificate of merger.

   Holders of our capital stock lose the right to appraisal if no petition for
appraisal is filed within 120 days after the filing of the certificate of
merger with the Delaware Secretary of State, or if a stockholder delivers to us
a written withdrawal of that stockholder's demand for an appraisal and an
acceptance of the merger, except that any such attempt to withdraw made more
than 60 days after the filing of the certificate of merger requires our written
approval. If appraisal rights are not perfected or a demand for appraisal
rights is withdrawn, a stockholder will be entitled to receive the
consideration otherwise payable pursuant to the merger agreement.

   If an appraisal proceeding is timely instituted, that proceeding may not be
dismissed as to any stockholder who has perfected a right of appraisal without
the approval of the Delaware Court of Chancery.

                                       35


                              THE MERGER AGREEMENT

   The following description summarizes the material provisions of the merger
agreement. We urge our stockholders to read carefully the merger agreement,
which is attached as Annex I to this proxy statement.

General

   The merger agreement provides that JWCH Merger Corp. will be merged with and
into InSight at the effective time of the merger. InSight will continue as the
surviving corporation in accordance with the Delaware General Corporation Law.
At the effective time of the merger, all the property, rights, privileges,
immunities, powers and franchises of InSight and JWCH Merger Corp. before the
merger will vest in the surviving corporation, and all debts, liabilities and
duties of InSight and JWCH Merger Corp. before the merger will become the
debts, liabilities and duties of the surviving corporation.

   The merger will be completed after all conditions in the merger agreement
are met or waived and InSight and JWCH Merger Corp. file a certificate of
merger with the Secretary of State of the State of Delaware. The merger
agreement provides that the closing of the merger will take place on the date
of the satisfaction or waiver of the conditions to the merger or such other
date mutually agreed upon by the parties.

Conversion of Shares

   The merger agreement provides that each issued and outstanding share of
InSight common stock, other than dissenting shares and shares owned by InSight,
InSight Holdings and JWCH Merger Corp., will be converted into the right to
receive $18 in cash, without interest. However, if, prior to the merger, the
outstanding shares of InSight capital stock are altered by reason of a stock
split, combination, reclassification or stock dividend, the merger
consideration will be adjusted accordingly.

Procedure for the Exchange of Stock Certificates

   Exchange of Stock Certificates. A bank or trust company designated by
InSight Holdings and reasonably acceptable to InSight will act as the paying
agent for the payment of the merger consideration. At the consummation of the
merger, InSight Holdings will deposit, or cause to be deposited, sufficient
cash with the paying agent in order to permit the payment of the merger
consideration. Promptly after the merger is completed, the paying agent will
mail transmittal forms and exchange instructions to each holder of record of
InSight capital stock. After receiving the transmittal form, each holder of
certificates formerly representing InSight capital stock will be able to
surrender the certificates to the paying agent and receive the merger
consideration. After the merger, each certificate formerly representing InSight
capital stock, until surrendered, will be deemed, for all purposes, to evidence
only the right to receive the merger consideration.

   Lost Certificates. If a certificate representing shares of InSight capital
stock shall have been lost, stolen or destroyed, upon the making of an
affidavit of that fact by the holder claiming such certificate to be lost,
stolen or destroyed and subject to such other reasonable conditions as the
board of directors of the surviving corporation may impose, the paying agent
shall issue in exchange for such lost, stolen or destroyed certificate, the
merger consideration payable in respect thereof. Prior to making payment,
InSight Holdings may, in its reasonable discretion, require the owner of the
lost, stolen or destroyed certificate to deliver a bond in a sum as it may
reasonably require as indemnity against any claim that may be made against
InSight Holdings, the surviving corporation or the paying agent with respect to
the certificate alleged to have been lost, stolen or destroyed.

   No Liability. None of InSight Holdings, JWCH Merger Corp., the paying agent
or InSight shall be liable to any former holder of InSight capital stock for
any such cash which is delivered to a public official pursuant to an official
request under any applicable abandoned property, escheat or similar law.

                                       36


   Withholding Right. Either the surviving corporation or the paying agent, on
behalf of the surviving corporation, is entitled to deduct and withhold from
the merger consideration payable to any former holder of shares of InSight
capital stock the amount it is required to deduct and withhold from the merger
consideration under the Internal Revenue Code or any provision of state, local
or foreign tax law. Any amounts withheld will be treated as having been paid
to the former holder of the InSight capital stock.

   Please do not send in any stock certificates with your proxies. Please wait
for the letter of transmittal and instructions from the paying agent.

No Solicitation

   The merger agreement provides that InSight shall not, and shall not permit
any of its directors, officers or employees, or any investment banker,
financial advisor, attorney, accountant or other representative retained by it
or any of its subsidiaries to, directly or indirectly:

  .  solicit, initiate or encourage, including by way of furnishing
     information, or take any other action to facilitate any inquiries or the
     making of any proposal that is or may reasonably be expected to lead to
     a takeover proposal, as described below; or

  .  participate in any discussions or negotiations regarding any takeover
     proposal;

provided that if, at any time prior to the date of the special meeting, the
InSight board of directors determines in good faith, after consultation with
outside counsel, that the failure to provide such information or participate in
such negotiations or discussions would result in the breach of its fiduciary
duties to InSight stockholders

                                       41


under applicable law, InSight and its representatives, in response to a written
superior proposal or a takeover proposal, which the InSight board of directors
concludes in good faith that there is a reasonable likelihood that such
takeover proposal could constitute a superior proposal, which was not solicited
by InSight or which did not otherwise result from a breach of the merger
agreement (and subject to InSight (a) providing InSight Holdings with three
business days prior written notice of InSight's decision to enter into the
negotiations and (b) orally and in writing promptly advising InSight Holdings
of the material terms and conditions of the takeover proposal or superior
proposal and the identity of the person making the takeover proposal or
superior proposal), InSight may:

  .  furnish, under a customary confidentiality agreement on no less
     favorable terms than the confidentiality agreements with the affiliates
     of InSight Holdings, information about InSight and its subsidiaries to
     any person making a superior proposal or takeover proposal; and

  .  participate in discussions or negotiations regarding that superior
     proposal or takeover proposal.

   The merger agreement provides that:

  .  the term "takeover proposal" means, whether in the form of a proposal or
     intended proposal, a signed agreement or completed action, as the case
     may be, any of the following: (a) a transaction or series of
     transactions pursuant to which any person (or group of persons) other
     than InSight Holdings and its affiliates acquires or would acquire,
     directly or indirectly, beneficial ownership (as defined in Rule 13d-3
     under the Securities Exchange Act of 1934) of more than 15% of the
     outstanding capital stock of InSight, whether from InSight or pursuant
     to a tender offer or exchange offer or otherwise; (b) any acquisition or
     proposed acquisition of, or business combination with, InSight or any of
     its subsidiaries, as the case may be, by a merger or other business
     combination (including any so-called "merger-of-equals" and whether or
     not InSight or any of its subsidiaries is the entity surviving any such
     merger or business combination); or (c) any merger, reorganization,
     consolidation, recapitalization, liquidation, extraordinary dividend,
     sale of assets or other similar transaction by or involving any person
     (or group of persons) other than InSight Holdings and its affiliates if,
     after giving effect thereto, the stockholders of InSight prior thereto
     beneficially own less than 85% of the outstanding voting stock or
     participating stock of the combined or ongoing entity (other than a
     transaction contemplated by the merger agreement); and

  .  the term "superior proposal" means any bona fide written proposal (on
     its most recently amended or modified terms, if amended or modified) by
     any person (or group of persons), other than InSight Holdings and its
     affiliates to enter into a takeover proposal, the effect of which would
     be that stockholders of InSight would beneficially own less than 40% of
     the voting stock, common stock and participating stock of the combined
     or ongoing entity, and which the InSight board of directors determines
     in its good faith judgment (after consultation with a financial advisor
     of nationally recognized reputation) to be more favorable to InSight's
     stockholders than the merger agreement, taking into account all relevant
     factors (including whether, in the good faith judgment of the InSight
     board of directors, after consultation with a financial advisor of
     nationally recognized reputation, the party making the proposal is
     reasonably able to finance the transaction and after consideration of
     any proposed adjustments to the merger agreement by InSight Holdings in
     response to such takeover proposal.

   Neither the InSight board of directors nor any committee of the board of
directors shall approve or recommend or execute or enter into any offer,
proposal, letter of intent, agreement in principle, merger agreement,
acquisition agreement, option agreement or other similar agreement related to
any takeover proposal, other than any such agreement entered into concurrently
with the termination of the merger agreement as described below.

   Notwithstanding the foregoing, in response to a superior proposal received
prior to the date of the special meeting which was not solicited by InSight and
which did not otherwise result from a breach of the provisions

                                       42


of the merger agreement, if the InSight board of directors determines in good
faith, after consultation with outside counsel, that it is necessary to do so
in order to comply with its fiduciary duties to the InSight stockholders under
applicable law, the InSight board of directors may terminate the merger
agreement and enter into a definitive agreement regarding the superior
proposal, but only at a time that is after the third business day following
InSight Holdings' receipt of written notice of the InSight board of directors'
intent to terminate the merger agreement. During this three business day
period, InSight shall provide an opportunity for InSight Holdings to make
adjustments in the terms and conditions of the merger agreement as would lead
InSight to proceed with the transactions contemplated by the merger agreement;
provided, that (a) any adjustments shall be at the discretion of the parties at
the time and (b) any decision of InSight to proceed with the superior proposal
or the transactions contemplated by the merger agreement (as amended by the
adjustments) is at the sole and absolute discretion of InSight. Prior to
terminating the merger agreement, InSight must pay a termination fee to InSight
Holdings. See "--Termination of the Merger Agreement" and "--Termination Fees;
Expenses."

Termination of the Merger Agreement

of the merger, whether before or after adoption of the merger agreement by the
InSight stockholders:

  .  by mutual agreement of InSight Holdings, JWCH Merger Corp. and InSight;

     and its subsidiaries for the fiscal year ended June 30, 2001 and
     delivery to InSight Holdings; provided, that the right to terminate the
     merger agreement shall not be available to any party whose failure to
     fulfill any obligation under the merger agreement has been the cause of,
     or resulted in, the failure of completion of the merger agreement to
     occur on or before such date;

  .  by InSight Holdings, JWCH Merger Corp. or InSight, if any court of
     competent jurisdiction in the United States or other United States
     governmental authority issues an order, decree, ruling or takes any
     other action restraining, enjoining or otherwise prohibiting the merger
     and that order, decree, ruling or other action has become final and
     nonappealable;

  .  by InSight Holdings, JWCH Merger Corp. or InSight, if the InSight
     stockholders do not adopt the merger agreement at the special meeting or
     any adjournment or postponement of that meeting; provided that, before
     InSight may terminate the merger agreement under this provision, InSight
     must have reimbursed InSight Holdings for its expenses up to $1 million;

  .  by InSight, at any time prior to the date of the special meeting of
     stockholders, in response to a superior proposal which was not solicited
     by InSight and which did not otherwise result from a breach of the

     notice requirements and paid the termination fee;

  .  by InSight, in the event InSight Holdings or JWCH Merger Corp.
     materially breaches its obligations under the merger agreement, unless
     such breach is cured within 30 days after written notice to InSight
     Holdings by InSight; or

  .  by InSight Holdings or JWCH Merger Corp., in the event InSight
     materially breaches its obligations under the merger agreement unless
     such breach is cured within 30 days after written notice to InSight by
     InSight Holdings or JWCH Merger Corp.

Termination Fees; Expenses

   If InSight Holdings, JWCH Merger Corp. or InSight elect to terminate the
merger agreement due to the failure of the InSight stockholders to approve the
merger agreement at the special meeting or any adjournment or postponement of
that meeting, then InSight shall reimburse InSight Holdings for its fees and
expenses

                                       43


incurred in connection with the transactions contemplated by the merger
agreement, up to a maximum of $1 million.

   In addition, if InSight terminates the merger agreement and enters into a
superior proposal, InSight must pay InSight Holdings a termination fee of $7
million, of which $5 million shall be payable immediately prior to the
termination and $2 million shall be payable upon the earlier of (a) 6 months
from the date of termination and (b) consummation of a superior proposal or
other takeover proposal.

   The merger agreement further provides that if InSight fails to pay the
termination fee when due and, in order to obtain payment of the fee, InSight
Holdings commences a suit which results in a judgment against InSight for the
fee, InSight must pay the costs and expenses of InSight Holdings, including
attorneys' fees and expenses, in connection with any action taken to collect
payment, together with interest on the amount of the fee.

  .  the merger agreement may be amended by the parties in writing at any
     time, except that after the merger agreement has been adopted by the
     InSight stockholders, no amendment may be entered into which by law
     requires further approval by the InSight stockholders unless that
     further approval is obtained; and

  .  at any time before the completion of the merger, a party may, by written
     instrument signed on behalf of that party, (a) extend the time for
     performance of any of the obligations or other acts of any other party

                          AGREEMENT AND PLAN OF MERGER

   AGREEMENT AND PLAN OF MERGER dated as of June 29, 2001 (this "Agreement"),
by and among INSIGHT HEALTH SERVICES HOLDINGS CORP., a Delaware corporation
("Parent"), JWCH MERGER CORP., a Delaware corporation ("Acquisition"), and
INSIGHT HEALTH SERVICES CORP., a Delaware corporation (the "Company").

                                   BACKGROUND

   A. Acquisition is a wholly-owned subsidiary of Parent and was formed to
merge with and into the Company so that, as a result of the merger, the Company
will survive and become a wholly-owned subsidiary of Parent.

   B. The Board of Directors of each of Parent, Acquisition and the Company has
determined that this Agreement and the merger of Acquisition with and into the
Company (the "Merger") in accordance with the provisions of the Delaware
General Corporation Law (the "DGCL"), and, subject to the terms and conditions
of this Agreement, is advisable and in the best interests of Parent,
Acquisition and the Company and their respective stockholders.

   C. The Board of Directors of each of Parent, Acquisition and the Company
have approved this Agreement, the Merger and the transactions contemplated
hereby.

   D. General Electric Company and the GE Fund (together, "GE") and TC Group,
L.L.C. and its Affiliates (collectively, "Carlyle"), holders of approximately
67% of the voting stock of the Company on an as if converted basis, in the
aggregate, have each entered into a Voting Agreement, of even date herewith,
whereby such stockholders have agreed, subject to the terms and conditions
contained therein, to vote in favor of the Merger and the adoption of this
Agreement.

                                   AGREEMENT

   NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements contained herein and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto intending to be legally bound do hereby
agree as follows:

   1. The Merger.

     1.1 General.

     (a) Upon the terms and subject to the conditions of this Agreement and
  in accordance with the DGCL, at the Effective Time, (i) Acquisition shall
  be merged with and into the Company, (ii) the separate corporate existence
  of Acquisition shall cease, and (iii) the Company shall be the surviving
  corporation (the "Surviving Corporation") and shall continue its corporate
  existence under the laws of the State of Delaware.

     (b) The Merger shall become effective at the time of filing of a
  certificate of merger substantially in the form of Exhibit A attached
  hereto, with the Secretary of State of the State of Delaware in accordance
  with the provisions of Section 251 of the DGCL (the "Certificate of
  Merger"), or at such later date as the parties may mutually agree (the
  "Effective Time"). Subject to the terms and conditions of this Agreement,
  the Company and Acquisition shall duly execute and file the Certificate of
  Merger with the Secretary of State of the State of Delaware at the time of
  the closing of the Merger (the "Closing"). The Closing shall take place at
  the offices of Kaye Scholer LLP, 425 Park Avenue, New York, New York 10022,
  on the date on which the last of the conditions set forth in Section 6 have
  been satisfied or waived or such other date as the parties hereto may
  mutually agree upon (the "Closing Date").


                                      I-1


     (c) At the Effective Time, the effects of the Merger shall be as
  provided in the applicable provisions of the DGCL. Without limiting the
  generality of the foregoing, and subject thereto, at the Effective Time,
  all the property, rights, privileges, powers and franchises of the Company
  and Acquisition shall vest in the Surviving Corporation, and all debts,
  liabilities, obligations, restrictions, disabilities and duties of the
  Company and Acquisition shall become the debts, liabilities, obligations,
  restrictions, disabilities and duties of the Surviving Corporation.

     1.2 Certificate of Incorporation. At the Effective Time, the Certificate
  of Incorporation of the Company, as in effect immediately prior to the
  Effective Time, shall be amended as set forth in Exhibit B and, as so
  amended, shall be the Certificate of Incorporation of the Surviving
  Corporation until thereafter amended as provided therein or by applicable
  law.

     1.3 Bylaws. The Bylaws of Acquisition, as in effect immediately prior to
  the Effective Time, shall be the Bylaws of the Surviving Corporation until
  thereafter amended as provided therein or by applicable law.

     1.4 Directors and Officers. From and after the Effective Time, (a) the
  directors of Acquisition at the Effective Time shall be the directors of
  the Surviving Corporation, each to hold office in accordance with the
  Certificate of Incorporation and Bylaws of the Surviving Corporation, and
  (b) the officers of the Company at the Effective Time shall be the initial
  officers of the Surviving Corporation, in each case, until their respective
  successors are duly elected or appointed and qualified.

     1.5 Effect on Company Common Stock; Conversion of Company Preferred
  Stock. Immediately prior to the Effective Time, the Company and the holders
  of the Company Preferred Stock shall cause all outstanding shares of
  Company Preferred Stock to be converted into shares of Company Common Stock
  so that, immediately prior to the Effective Time, no shares of Company
  Preferred Stock shall remain outstanding. At the Effective Time, by virtue
  of the Merger and without any action on the part of Parent, Acquisition,
  the Company or the holders of any of the following securities:

     (a) each issued and outstanding share of common stock of Acquisition
  shall be converted into one validly issued, fully paid and nonassessable
  share of common stock, no par value per share, of the Surviving
  Corporation;

     (b) each share of Company Common Stock owned or held in treasury by the
  Company and each share of Company Common Stock owned by Acquisition or
  Parent shall be canceled and retired without any conversion thereof and no
  payment or distribution shall be made with respect thereto; and

     (c) subject to the provisions of Section 1.8, each share of Company
  Common Stock issued and outstanding immediately prior to the Effective Time
  (other than shares of Company Common Stock canceled and retired in
  accordance with Section 1.5(b) and any Dissenting Shares) shall be
  converted into the right to receive $18.00 in cash per share, without
  interest (the "Merger Consideration"). As of the Effective Time, each share
  of Company Common Stock shall no longer be outstanding and shall
  automatically be canceled and retired, and each holder of record of a
  certificate representing any such shares (a "Certificate") shall cease to
  have any rights with respect thereto, other than the right to receive the
  Merger Consideration, in accordance with Section 1.8.

     (d) Notwithstanding any provision of this Agreement to the contrary, if
  required by the DGCL but only to the extent required thereby, shares of
  Company Capital Stock that are issued and outstanding immediately prior to
  the Effective Time and that are held by holders of such shares of Company
  Capital Stock who have properly exercised appraisal rights with respect
  thereto in accordance with Section 262 of the DGCL (the "Dissenting
  Shares") will not be converted into the right to receive the Merger
  Consideration, and the holders of such Dissenting Shares will be entitled
  to receive payment of the appraised value of such shares of Company Capital
  Stock in accordance with the provisions of such Section 262 of the DGCL
  unless and until such holders fail to perfect or effectively withdraw or
  lose their rights to appraisal and payment under the DGCL. If, after the
  Effective Time, any such holder fails to perfect or effectively withdraws
  or loses such right, such shares of Company Capital Stock will thereupon

                                      I-2


  be treated as if they had been converted into and become exchangeable for,
  at the Effective Time, the right to receive the Merger Consideration,
  without any interest thereon. The Company shall (i) give Parent prompt
  notice of any demands received by the Company for appraisals of shares of
  Company Capital Stock and (ii) consult with and keep Parent informed, on an
  on-going basis, regarding the status and negotiation of such demands. The
  Company shall not make any payment or settlement offer, or agree to or
  effect any settlement, prior to the Effective Time with respect to any such
  demand unless Parent shall have consented in writing to such payment or
  settlement offer, which consent shall not be unreasonably withheld.

     1.6 Company Stock Options; Warrants.

     (a) As of the Effective Time, each outstanding option to purchase shares
  of Company Common Stock under the Company Stock Plans (individually, a
  "Company Stock Option" and collectively, the "Company Stock Options") shall
  be canceled and retired by virtue of the Merger and each holder of a
  Company Stock Option shall cease to have any rights with respect thereto,
  other than the right to receive the Option Consideration, if any, in
  accordance with this Section 1.6(a). Except as set forth on Schedule 1.6,
  each holder of a Company Stock Option, whether or not then exercisable,
  shall be entitled to receive in cash an amount determined by multiplying
  (i) the excess, if any, of the Merger Consideration over the exercise price
  per share provided in such Company Stock Option, by (ii) the number of
  shares of Company Common Stock subject to such Company Stock Option (such
  amount being hereinafter referred to as the "Option Consideration").
  Payment of the Option Consideration shall be made by the Company, subject
  to the terms and conditions of this Agreement, as soon as practicable after
  consummation of the Merger and receipt by the Company of the surrendered
  option agreement representing such Company Stock Option and a written
  instrument, reasonably satisfactory to Parent, duly executed by the holder
  of such Company Stock Option setting forth (x) a representation by such
  holder that he or she is the owner of all options represented by such
  Company Stock Option and (y) a confirmation of, and consent to, the
  cancellation of all of the options represented by such Company Stock
  Option. All amounts payable pursuant to this Section 1.6(a) shall be
  subject to any required withholding of taxes and shall be paid without
  interest. At the Effective Time, the Company Stock Plans shall terminate.

     (b) As of the Effective Time, each outstanding Warrant shall be canceled
  and retired by virtue of the Merger and each holder of a Warrant shall
  cease to have any rights with respect thereto, other than the right to
  receive the Warrant Consideration, if any, in accordance with this Section
  1.6(b). Each holder of a Warrant, whether or not then exercisable, shall be
  entitled to receive in cash an amount determined by multiplying (i) the
  excess, if any, of the Merger Consideration over the exercise price per
  share provided in such Warrant, by (ii) the number of shares of Company
  Common Stock subject to such Warrant (such amount being hereinafter
  referred to as the "Warrant Consideration"). Payment of the Warrant
  Consideration shall be made by the Company, subject to the terms and
  conditions of this Agreement, as soon as practicable after consummation of
  the Merger and receipt by the Company of the surrendered Warrant and a
  written instrument, reasonably satisfactory to Parent, duly executed by the
  holder of such Warrant setting forth (x) a representation by such holder
  that he or she is the owner of all rights represented by such Warrant and
  (y) a confirmation of, and consent to, the cancellation of such Warrant.
  All amounts payable pursuant to this Section 1.6(b) shall be subject to any
  required withholding of taxes and shall be paid without interest.

     1.7 Adjustment of the Merger Consideration. In the event that, prior to
  the Effective Date, any stock split, combination, reclassification or stock
  dividend with respect to the Company Common Stock or the Company Preferred
  Stock (collectively, the "Company Capital Stock"), any change or conversion
  of Company Capital Stock into other securities or any other dividend or
  distribution with respect to the Company Capital Stock (other than regular
  quarterly dividends) should occur or, if a record date with respect to any
  of the foregoing should occur, appropriate and proportionate adjustments
  shall be made to the Merger Consideration, and thereafter all references to
  the Merger Consideration shall be deemed to be to the Merger Consideration
  as so adjusted.

                                      I-3


     1.8 Exchange Procedures; Stock Transfer Books.

     (a) Prior to the Effective Time, Parent shall appoint a commercial bank
  or trust company, which shall be reasonably satisfactory to the Company, to
  act as paying agent hereunder (the "Paying Agent") for payment of the
  Merger Consideration upon surrender of a Certificate. Prior to or
  concurrently with the Effective Time, Parent shall cause Acquisition or the
  Surviving Corporation, as the case may be, to provide the Paying Agent with
  cash in an amount necessary to pay for all the shares of Company Common
  Stock pursuant to Section 1.5(c). Such amounts shall hereinafter be
  referred to as the "Exchange Fund."

     (b) As soon as practicable after the Effective Time, Parent shall use
  its reasonable efforts to cause the Paying Agent to send to each Person who
  was, at the Effective Time, a holder of record of Certificates which shares
  were converted into the right to receive the Merger Consideration pursuant
  to Section 1.5(c), a letter of transmittal which (i) shall specify that
  delivery shall be effected and risk of loss and title to such Certificates
  shall pass, only upon actual delivery thereof to the Paying Agent, and (ii)
  shall contain instructions for use in effecting the surrender of the
  Certificates in exchange for the Merger Consideration. Upon surrender of a
  Certificate to the Paying Agent together with such letter of transmittal,
  duly executed and completed in accordance with the instructions thereto,
  and such other documents as may reasonably be required by the Paying Agent,
  the holder of such Certificate shall promptly receive in exchange therefor
  the Merger Consideration.

     (c) If any Merger Consideration is to be paid to any Person other than
  the registered holder of the Certificate surrendered in exchange therefor,
  it shall be a condition to such exchange that such surrendered Certificate
  shall be properly endorsed and otherwise in proper form for transfer and
  such Person either (i) shall pay to the Paying Agent any transfer or other
  taxes required as a result of the distribution of such cash payment to such
  Person, or (ii) shall establish to the reasonable satisfaction of the
  Paying Agent that such tax has been paid or is not applicable. Parent or
  the Paying Agent shall be entitled to deduct and withhold from the
  consideration otherwise payable pursuant to this Agreement to any holder of
  shares of Company Common Stock such amounts as Parent or the Paying Agent
  is required to deduct and withhold with respect to the making of such
  payment under the Code, or any provision of state, local or foreign tax
  law. To the extent that amounts are so withheld by Parent or the Paying
  Agent, such withheld amounts shall be treated for all purposes of this
  Agreement as having been paid to the holder of the shares of Company Common
  Stock in respect of which such deduction and withholding was made by Parent
  or the Paying Agent. All amounts in respect of taxes received or withheld
  by Parent shall be disposed of by Parent in accordance with the Code or
  such state, local or foreign tax law, as applicable.

     (d) As of the Effective Time, all shares of Company Common Stock (other
  than shares of Company Common Stock to be canceled and retired in
  accordance with Section 1.5(b) and any Dissenting Shares) issued and
  outstanding immediately prior to the Effective Time shall cease to be
  outstanding and shall automatically be canceled and retired and shall cease
  to exist, and each holder of any such shares shall cease to have any rights
  with respect thereto, except the right to receive the Merger Consideration
  upon surrender of the Certificate representing such shares in accordance
  with this Section 1.8. The Merger Consideration paid upon the surrender of
  Certificates in accordance with the terms of this Section 1.8 shall be
  deemed to have been delivered (and paid) in full satisfaction of all rights
  pertaining to the Company Common Stock previously represented by such
  Certificates.

     (e) If any Certificate 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 subject to such other
  reasonable conditions as the Board of Directors of the Surviving
  Corporation may impose, the Paying Agent shall issue in exchange for such
  lost, stolen or destroyed Certificate, the Merger Consideration payable in
  respect thereof, pursuant to this Agreement; provided, that Parent may, in
  its reasonable discretion and as a condition precedent to the issuance
  thereof, require the owner of such lost, stolen or destroyed Certificate to
  deliver a bond in such sum as it may reasonably require as indemnity
  against any claim that may be made against Parent, the Surviving
  Corporation or the Paying Agent with respect to the Certificate alleged to
  have been lost, stolen or destroyed.

                                      I-4


     (f) At the Effective Time, the stock transfer books of the Company shall
  be closed and thereafter there shall be no further registration oftransfers
  of shares of Company's capital stock on the records of the Company.

     (g) The Paying Agent shall invest any cash included in the Exchange Fund
  as directed by Parent on a daily basis; provided, that no such investment
  or loss thereon shall affect the amounts payable to the Company's
  stockholders pursuant to Section 1. Any interest and other income resulting
  from such investments shall promptly be paid to Parent.

     1.9 Return of Exchange Fund. Any portion of the Exchange Fund which
  remains undistributed to the former holders of Company Common Stock for 180
  days after the Effective Time shall be delivered to Parent, upon its
  request, and any such former holders who have not theretofore surrendered
  to the Paying Agent their Certificates in compliance herewith shall
  thereafter look only to Parent for payment of their claim for the Merger
  Consideration. None of Parent, Acquisition, the Paying Agent or the Company
  shall be liable to any former holder of Company Common Stock for any such
  cash held in the Exchange Fund which is delivered to a public official
  pursuant to an official request under any applicable abandoned property,
  escheat or similar law.

     1.10 Further Assurances. If at any time after the Effective Time, the
  Surviving Corporation shall consider or be advised that any deeds, bills of
  sale, assignments or assurances 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 its right, title or interest in, to
  or under any of the rights, privileges, powers, franchises, properties or
  assets of either the Company or Acquisition, or (b) otherwise to carry out
  the purposes of this Agreement, the Surviving Corporation and its proper
  officers and directors or their designees shall be authorized to execute
  and deliver, in the name and on behalf of either the Company or
  Acquisition, all such deeds, bills of sale, assignments and assurances and
  do, in the name and on behalf of the Company or Acquisition, all such other
  acts and things necessary, desirable or proper to vest, perfect or confirm

  powers, franchises, properties or assets of the Company or Acquisition, as
  applicable, and otherwise to carry out the purposes of this Agreement.

  any statute of limitations in respect of Taxes or agreed to any extension
  of time with respect to a Tax assessment or deficiency, other than those
  which are not reasonably likely to have a Material Adverse Effect on the
  Company. The Company and each of its Subsidiaries have withheld or
  collected and paid over to the appropriate governmental authorities (or are

  or collected. Neither the Company nor any of its Subsidiaries has made an

  Effect on the Company.

     (f) There is no existing tax sharing agreement or other agreement or
  arrangement with respect to Taxes of a Person other than the Company and
  its Subsidiaries that may or will require that any payment be made by the
  Company or any of its Subsidiaries to any such other person after the
  Closing Date.

  supplemental retirement, severance and other similar employee benefit

  circumstances in connection with which the Company or any of its
  Subsidiaries or, to the actual knowledge of the Company's executive
  officers and any other officer having primary responsibility for such
  matters, any of the Managed Entities could be subject to any liability that
  is reasonably likely to be material to the Company and its Subsidiaries
  under ERISA, the Code or any other applicable law.

     (d) With respect to the Company Benefit Plans, there are no material
  funded benefit obligations for which material contributions have not been
  made or properly accrued and there are no material unfunded benefit

reference to the particular subsection of this Agreement to which exception is
being taken, Parent and Acquisition represent and warrant to the Company as
follows:

     3.1 Organization, Standing and Corporate Power. Each of Parent and
  Acquisition is a corporation or other legal entity duly organized, validly
  existing and in good standing under the laws of the jurisdiction in which
  it is organized and has the requisite corporate or other power, as the case
  may be, and authority to carry on its business as now being conducted,
  except for those jurisdictions where the failure to be so organized,
  existing or in good standing would not reasonably be expected to have a
  Material Adverse Effect on Parent. Each of Parent and Acquisition is duly
  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 its business or the ownership, leasing or operation of
  its properties makes such qualification or licensing necessary, except for
  those jurisdictions where the failure to be so qualified or licensed or to
  be in good standing would not reasonably be expected to have a Material
  Adverse Effect on Parent.

  to, directly or indirectly through another Person, (i) solicit, initiate or

  any Takeover Proposal; provided, however, that if at any time prior to
  obtaining the Company Stockholder Approval at the Company Stockholders
  Meeting, the Board of Directors of the Company determines in good faith,
  after consultation with outside counsel, that the failure to provide such
  information or participate in such negotiations or discussions would result
  in the breach of the fiduciary duties of the Board of Directors of the
  Company to the Company's stockholders under applicable Law, then the
  Company and its representatives may, in response to any such written
  proposal that has been determined by it to be a Superior Proposal or a
  Takeover Proposal that the Board of Directors of the Company concludes in
  good faith that there is a reasonable likelihood that such Takeover
  Proposal could constitute a Superior Proposal, which was not solicited by
  it or which did not otherwise result from a breach of this Section 5.2(a),
  and subject to providing at least three business days prior written notice
  of its decision to take such action to Parent and compliance with Section
  5.2(c), (x) furnish

                                      I-22


  information with respect to the Company and its Subsidiaries to any Person
  making such a Superior Proposal or Takeover Proposal pursuant to a
  customary confidentiality agreement containing terms no less restrictive
  than the terms of the confidentiality agreement entered into between the
  Company and Parent or any Affiliate thereof provided that a copy of all
  such information is delivered simultaneously to Parent, after consultation
  with its outside counsel, and (y) participate in discussions or
  negotiations regarding such Superior Proposal or Takeover Proposal.

     (b) Neither the Board of Directors of the Company nor any committee
  thereof shall approve or recommend, or execute or enter into, any offer,
  proposal, letter of intent, agreement in principle, merger agreement,
  acquisition agreement, option agreement or other similar agreement (each,
  an "Acquisition Agreement") related to any Takeover Proposal, other than
  any such agreement entered into concurrently with a termination pursuant to
  the next sentence in order to facilitate such action. Notwithstanding the
  foregoing, in response to a Superior Proposal, if the Board of Directors of
  the Company determines in good faith, after consultation with outside
  counsel, that the failure to do so would result in a breach of its
  fiduciary duties to the Company's stockholders under applicable Law, the
  Board of Directors of the Company may (subject to this and the following
  sentence) terminate this Agreement in accordance with Section 7(d) (and
  concurrently with such termination, cause the Company to enter into an
  Acquisition Agreement with respect to such Superior Proposal), but only at
  a time that is after the third business day following Parent's receipt of
  written notice advising Parent that the Board of Directors of the Company
  is prepared to terminate this Agreement and accept a Superior Proposal,
  specifying the material terms and conditions of such Superior Proposal and
  identifying the Person making such Superior Proposal. During the three
  business day period set forth in the immediately preceding sentence, the
  Company shall provide an opportunity for Parent to make adjustments in the
  terms and conditions of this Agreement as would lead the Company to proceed
  with the transactions contemplated by this Agreement (as amended by such
  adjustments); provided, however, that (i) any such adjustments shall be at
  the discretion of the parties at the time and (ii) any decision of the
  Company to proceed with the Superior Proposal or the transactions
  contemplated by this Agreement (as amended by such adjustments) is at the
  sole and absolute discretion of the Company.

     (c) In addition to the obligations of the Company set forth in
  paragraphs (a) and (b) of this Section 5.2, the Company shall promptly
  advise Parent orally and in writing of any request for information or of
  any Takeover Proposal or Superior Proposal, the material terms and
  conditions of such request, Takeover Proposal or Superior Proposal and the
  identity of the Person making such request, Takeover Proposal or Superior
  Proposal and keep Parent informed of the status (including amendments or
  proposed amendments to) of such request for information, Takeover Proposal
  or Superior Proposal on a continuing basis.

     (d) For purposes of this Agreement, (i) "Takeover Proposal" means,
  whether in the form of a proposal or intended proposal, a signed agreement
  or completed action, as the case may be, any of the following: (A) a
  transaction or series of transactions pursuant to which any Person (or
  group of Persons) other than Parent and its Affiliates (a "Third Party")
  acquires or would acquire, directly or indirectly, beneficial ownership (as
  defined in Rule 13d-3 under the Exchange Act) of more than 15% of the
  outstanding capital stock of the Company, whether from the Company or
  pursuant to a tender offer or exchange offer or otherwise; (B) any
  acquisition or proposed acquisition of, or business combination with, the
  Company or any of its Subsidiaries, as the case may be, by a merger or
  other business combination (including any so-called "merger-of-equals" and
  whether or not the Company or any of its Subsidiaries is the entity
  surviving any such merger or business combination); or (C) any merger,
  reorganization, consolidation, recapitalization, liquidation, extraordinary
  dividend, sale of assets or other similar transaction by or involving a
  Third Party if, after giving effect thereto, the stockholders of the
  Company prior thereto beneficially own less than 85% of the outstanding
  voting stock or participating stock of the combined or ongoing entity
  (other than a transaction contemplated by this Agreement); and (ii) a
  "Superior Proposal" means any bona fide written proposal (on its most
  recently amended or modified terms, if amended or modified) made by a Third
  Party to enter into a Takeover Proposal, the effect of which would be that
  stockholders of the Company would beneficially own less than 40% of the
  voting

                                      I-23


  stock, common stock and participating stock of the combined or ongoing
  entity, and which the Board of Directors of the Company determines in its
  good faith judgment (after consultation with a financial advisor of
  nationally recognized reputation) to be more favorable to the Company's
  stockholders than the Merger, taking into account all relevant factors
  (including whether, in the good faith judgment of the Board of Directors of
  the Company, after consultation with a financial advisor of nationally
  recognized reputation, the Third Party is reasonably able to finance the
  transaction and after consideration of any proposed adjustments to this
  Agreement by Parent in response to such Takeover Proposal as contemplated
  by Section 5.2(b)).

     (e) Nothing contained in this Section 5.2 shall prohibit the Company
  from taking and disclosing to its stockholders a position contemplated by
  Rule 14e-2(a) promulgated under the Exchange Act; provided, however, that
  in no event shall the Company or its Board of Directors take or agree or
  resolve to take any action or make any recommendation inconsistent with the
  terms of this Agreement unless the Company (i) determines that the tender
  offer to which its statement pursuant to Rule 14e-2(a) relates constitutes
  a Superior Proposal, (ii) complies with the notice and waiting period
  provisions under Sections 5.2(a) and (b), (iii) terminates this Agreement
  pursuant to Section 7(d) and (iv) pays the Termination Fee to Parent as
  required by Sections 5.7(b) and 7(d).

  to the Company's stockholders as promptly as practicable after the Company
  Proxy Statement is cleared by the SEC. The Company shall provide Parent
  with a copy of the preliminary Company Proxy Statement and all
  modifications thereto prior to filing or delivery to the SEC and will
  consult with Parent in connection therewith and consider in good faith
  comments provided by Parent regarding the Company Proxy Statement. The
  Company will inform Parent, promptly after it receives notice thereof, of
  any request by the SEC for the amendment of the Company Proxy Statement or
  comments thereon and responses thereto or requests by the SEC for
  additional information, and will furnish to Parent copies of all
  correspondence between the Company or any of its representatives, on the
  one hand, and the SEC or its staff, on the other hand, with respect to the
  Company Proxy Statement, the Merger or any other filings in connection
  herewith or therewith and will consult with Parent in connection therewith.
  If at any time prior to the Effective Time any information relating to the
  Company or Parent, or any of their respective affiliates, officers or
  directors, should be discovered by the Company or Parent which should be
  set forth in an amendment or supplement to the Company Proxy Statement, so
  that any of such document would not include any misstatement of a material
  fact or omit to state any material fact necessary to make the statements
  therein, in light of the circumstances under which they were made, not
  misleading, the party that discovers such information shall promptly notify
  the other parties hereto and an appropriate amendment or supplement
  describing such information shall be promptly filed with the SEC and, to
  the extent required by law, disseminated to the stockholders of the
  Company.

     (b) The Company shall establish a record date (which will be as soon as
  practicable following the date of this Agreement) for and take all
  necessary steps under all applicable Laws, duly call, give notice of,
  convene and hold a meeting of its stockholders (the "Company Stockholders
  Meeting") solely for the purpose of obtaining the Company Stockholder
  Approval.

     (c) Subject only to the Company's ability to terminate this Agreement
  pursuant to Sections 5.2 and 7(d) hereof, the Board of Directors of the
  Company shall recommend to its stockholders the approval of this Agreement
  and the transactions contemplated hereby and use its reasonable best
  efforts to obtain Company Stockholder Approval.

     5.4 Reasonable Best Efforts.

     (a) Upon the terms and subject to the conditions set forth in this
  Agreement, each of the parties agrees to use its reasonable best efforts to
  take, or cause to be taken, all actions, and to do, or cause to be

                                      I-24


  done, and to assist and cooperate with the other parties in doing, all
  things necessary, proper or advisable under applicable Laws to consummate
  and make effective, in the most expeditious manner practicable, the Merger
  and the other transactions contemplated by this Agreement, including (i)
  the obtaining of all necessary actions or nonactions, waivers, consents and
  approvals from Governmental Entities and the making of all necessary
  registrations and filings and the taking of all steps as may be necessary
  to obtain an approval or waiver from, or to avoid an action or proceeding
  by, any Governmental Entity, (ii) the obtaining of all necessary consents,
  approvals or waivers from third parties, (iii) the defending of any
  lawsuits or other legal proceedings, whether judicial or administrative,
  challenging this Agreement or the consummation of the transactions
  contemplated by this Agreement, including seeking to have any stay or
  temporary restraining order entered by any court or other Governmental
  Entity vacated or reversed, and (iv) the execution and delivery of any
  additional instruments necessary to consummate the transactions
  contemplated by, and to fully carry out the purposes of, this Agreement.
  Nothing in this Section 5.4(a) shall be construed to require any party to
  participate in any threatened or actual Legal Proceeding (other than Legal
  Proceedings to which it is a party or subject or threatened to be made a
  party or subject) in connection with the consummation of the transactions
  contemplated by this Agreement unless such party shall consent in advance
  in writing to such participation.

     (b) In connection with and without limiting the foregoing, the Company
  and Parent shall (i) take all action reasonably necessary to ensure that no
  state takeover statute or similar statute or regulation is or becomes
  applicable to the Merger, this Agreement, or any of the other transactions
  contemplated by this Agreement and (ii) if any state takeover statute or
  similar statute or regulation becomes applicable to the Merger, this
  Agreement, or any other transaction contemplated by this Agreement, take
  all action reasonably necessary to ensure that the Merger and the other
  transactions contemplated by this Agreement may be consummated as promptly
  as practicable on the terms contemplated by this Agreement and otherwise to
  minimize the effect of such statute or regulation on the Merger and the
  other transactions contemplated by this Agreement.

     5.5 Employee Benefit Plans; Existing Agreement.

     (a) After the Effective Time, Parent shall cause the Surviving
  Corporation to provide to the employees of the Company substantially
  similar benefit plans, programs and arrangements provided to employees of
  the Company as of the date hereof.

     (b) With respect to each benefit plan, program, practice, policy or
  arrangement maintained by the Surviving Corporation (the "Surviving
  Corporation Plans") in which employees of the Company subsequently
  participate, for purposes of determining vesting, accrual and entitlement
  to benefits, including for severance benefits, pension benefits and
  vacation entitlement, service with the Company (or predecessor employers to
  the extent the Company provides past service credit) shall be treated as
  service with Surviving Corporation; provided, that such service shall not
  be recognized to the extent that such recognition would result in a
  duplication of benefits. Such service also shall apply for purposes of
  satisfying any waiting periods, evidence of insurability requirements, or
  the application of any pre-existing condition limitations. Each Surviving
  Corporation Plan shall waive pre-existing condition limitations to the same
  extent waived under the applicable Company Benefit Plan. Company employees
  shall be given credit for amounts paid under a corresponding benefit plan
  during the same period for purposes of applying deductibles, copayments and
  out-of-pocket maximums as though such amounts had been paid in accordance
  with the terms and conditions of the Surviving Corporation Plan for the
  plan year in which the Effective Time occurs.

     5.6 Indemnification.

     (a) From and after the Effective Time, Parent shall cause the Surviving
  Corporation to, fulfill and honor in all respects (i) the obligations of
  the Company to indemnify each Person who is or was a director or officer
  (an "Indemnified Party") of the Company or any of its Subsidiaries pursuant
  to any indemnification provisions of the Company's Certificate of
  Incorporation or Bylaws as each is in effect on the date hereof, and (ii)
  any indemnification agreements of the Company, as each is in effect on the
  date

                                      I-25


  hereof, shall be assumed by the Surviving Corporation in the Merger,
  without further action, as of the Effective Time and shall survive the
  Merger and shall continue in full force and effect in accordance with their
  terms, and Parent shall cause the Surviving Corporation to honor all such
  rights. Without limitation to the foregoing, Parent shall cause the
  Surviving Corporation to include and cause to be maintained in effect in
  the Surviving Corporation's (or any successor's) certificate of
  incorporation and bylaws after the Effective Time, provisions regarding the
  elimination of liability of directors, indemnification of officers,
  directors and employees and the advancement of expenses, which are, in the
  aggregate, no less advantageous to the intended beneficiaries than the
  corresponding provisions contained in the Company's Certificate of
  Incorporation and Bylaws as in effect on the date hereof.

     (b) For a period of six years after the Effective Time, Parent shall
  cause to be maintained in effect the current officers' and directors'
  liability insurance maintained by the Company with respect to the
  Indemnified Parties (provided, that Parent may substitute therefor policies
  of at least the same coverage and amounts containing terms and conditions
  which are no less advantageous to the Indemnified Parties than such
  existing insurance) covering acts or omissions occurring prior to the
  Effective Time; provided, that Parent shall not be required in order to
  maintain or procure such coverage to pay an annual premium in excess of
  175% 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, Parent
  shall only be required to obtain as much coverage as can be obtained by
  paying an annual premium equal to the Cap.

     (c) This Section 5.6 shall survive the closing of all the transactions
  contemplated hereby, is intended to benefit the Indemnified Parties and
  their respective heirs and personal representative (each of which shall be
  entitled to enforce this Section 5.6 against Parent and the Surviving
  Corporation, as the case may be, as a third-party beneficiary of this
  Agreement), and shall not be terminated or modified in such a manner to
  adversely affect any Indemnified Party without the consent of such
  Indemnified Party.

     5.7 Fees and Expenses.

     (a) Except as provided in this Section 5.7, all fees and expenses
  incurred in connection with the Merger, this Agreement, and the
  transactions contemplated by this Agreement shall be paid by the party
  incurring such fees or expenses, whether or not the Merger is consummated,
  except that Parent and the Company shall each pay 50% of the filing fees
  (i) for the pre-merger notification and report forms under the HSR Act and
  (ii) associated with any filing made with the SEC.

     (b) In the event that this Agreement is to be terminated by either
  Parent or the Company pursuant to Section 7(c), then the Company shall pay
  Parent by wire transfer of same day funds all fees and expenses (including,
  but not limited to, fees of legal, accounting and other professionals and
  consultants, investment banking and other advisory fees and expenses, fees
  and expenses of banks and other financial institutions, print, travel and
  fees paid to governmental and similar entities) incurred by Parent or any
  Affiliate of Parent in connection with the transactions contemplated by
  this Agreement (collectively, the "Parent Expenses") immediately prior to
  such termination, not to exceed $1,000,000. In the event that this
  Agreement is to be terminated by the Company pursuant to Section 7(d), then
  the Company shall pay Parent a fee equal to $7,000,000 (the "Termination
  Fee"), of which $5,000,000 shall be payable immediately prior to such
  termination and $2,000,000 shall be payable by wire transfer of same day
  funds upon the earlier to occur of (i) 6 months from the date of
  termination of this Agreement and (ii) the consummation of any such
  Superior Proposal or other Takeover Proposal. The Company acknowledges that
  the agreements contained in this Section 5.7(b) are an integral part of the
  transactions contemplated by this Agreement and that, without these
  agreements, Parent would not enter into this Agreement. Accordingly, if the
  Company fails promptly to pay the amount due pursuant to this Section
  5.7(b), and, in order to obtain such payment, Parent commences a suit which
  results in a judgment against the Company for the fee set forth in this
  Section 5.7(b), the Company shall pay to Parent its costs and expenses
  (including reasonable attorneys' fees and expenses) in connection with such
  suit, together with interest on

                                      I-26


  the amount of the fee at the prime rate of Bank of America in effect on the
  date such payment was required to be made.

     5.8 Public Announcements. Parent and the Company will consult with each
  other before issuing, and provide each other the opportunity to review,
  comment upon and concur with, any press release or other public statements
  with respect to the transactions contemplated by this Agreement, including
  the Merger, and shall not issue any such press release or make any such
  public statement prior to such consultation, except as either party may
  determine is required by applicable Law (after consultation with its
  outside counsel), court process or by obligations pursuant to any listing
  agreement with any national securities exchange or national trading system.
  The parties agree that the initial press release to be issued with respect
  to the transactions contemplated by this Agreement shall be in the form
  heretofore agreed to by the parties.

     5.9 Stockholder Litigation. The Company shall give Parent the
  opportunity to participate in the defense of any stockholder litigation
  against the Company and/or its directors relating to the transactions
  contemplated by this Agreement. The Company shall not make any payment or
  settlement offer prior to the Effective Time with respect to any such
  litigation unless Parent shall have consented in writing to such payment or
  settlement, which consent shall not be unreasonably withheld.

     5.10 Financing. Prior to the Closing, Parent and Acquisition will use
  their reasonable best efforts to enter into definitive agreements on terms
  and conditions substantially in accordance with the Financing Commitments
  (the "Definitive Financing Agreements"). Parent and Acquisition will use
  their reasonable best efforts, and will cause their affiliates to use their
  reasonable best efforts, to comply with the terms and satisfy the
  conditions of the Financing Commitments and the Definitive Financing
  Agreements. Parent will furnish correct and complete copies of the
  Definitive Financing Agreements to Company promptly upon their execution.
  Parent will consummate the equity financing contemplated by the equity
  commitment letters referred to in Section 3.5(iii) and (iv) on the Closing
  Date. For purposes of this Section 5.10, "reasonable best efforts" shall
  not be deemed to require that Parent compromise any of the economic or
  other material terms contained in the Financing Commitments.

     5.11 HSR Filings. The Company and Parent will file, or cause to be
  filed, as promptly as practicable after the date of this Agreement, with
  the United States Federal Trade Commission and the Antitrust Division of
  the United States Department of Justice pursuant to the HSR Act, including
  all requisite documents, materials and information therefor, and request
  early termination of the waiting period under the HSR Act. Each of the
  Company and Parent shall furnish to the other such necessary information
  and reasonable assistance as the other may request in connection with its
  preparation of any filing or submission which is necessary under the HSR
  Act. The Company and Parent shall each keep the other apprised of the
  status of any inquiry or requests for additional information made by any
  governmental authority and shall comply with any such inquiry or request.

     5.12 Cooperation Regarding The Financing Commitments. From and after the
  date of this Agreement, the Company shall use its reasonable best efforts
  to cause its Subsidiaries, officers, employees and representatives to (a)
  cooperate with Parent and Parent's Affiliates in connection with the
  arrangement of the Financing Commitments and any other financing to be
  consummated contemporaneously with the transactions contemplated by this
  Agreement, including, without limitation, the execution and delivery, at
  the Closing, of any pledge or security documents, underwriting or placement
  arrangements, other definitive financing documents or other requested
  certificates or financial information, including a certificate of the chief
  financial officer of the Company with respect to solvency matters, comfort
  letters of accountants and legal opinions, in each case, as may be
  reasonably requested by Parent or Parent's Affiliates in connection with
  such financing, (b) actively assist in marketing such financing, which
  marketing assistance shall include, but not be limited to, (i) assisting in
  the preparation of road show materials and supplementing and updating any
  such materials, (ii) participating in road show presentations (including

  or supplements thereto, and (c) cooperate with Parent and Parent's
  Affiliates to commence and consummate the Tender Offer, including, but not
  limited to the preparation and filing of tender offer documentation if
  required by Parent or Parent's Affiliates. Parent shall keep the Company
  reasonably informed as to the progress of such Financing Commitments and,
  as consistent with Section 5.1(d), shall promptly inform the Company if
  Parent has reason to believe that the financing required to consummate the
  transactions contemplated by this Agreement will not be available to Parent
  on the terms and conditions set forth in the Financing Commitments and the
  Definitive Financing Agreements, as applicable, or at all.

                        [LETTERHEAD OF UBS WARBURG LLC]

                                 June 29, 2001

The Board of Directors
InSight Health Services Corp.
4400 MacArthur Boulevard, Suite 800
Newport Beach, California 92660

Dear Members of the Board:

   We understand that InSight Health Services Corp. ("InSight") proposes to
enter into an Agreement and Plan of Merger, dated as of June 29, 2001 (the
"Agreement"), by and among InSight Health Services Holdings Corp.
("Purchaser"), a joint venture formed by J.W. Childs Associates, L.P. ("JWC")
and The Halifax Group, L.L.C. ("Halifax"), JWCH Merger Corp., a wholly owned
subsidiary of Purchaser ("Merger Sub"), and InSight pursuant to which (i)
Merger Sub will merge with and into InSight (the "Merger") and (ii) each
outstanding share of the common stock, par value $0.001 per share, of InSight
("InSight Common Stock") will be converted into the right to receive $18.00 in
cash, without interest (the "Merger Consideration"). The terms and conditions
of the Merger are more fully set forth in the Agreement and related documents.

   You have requested our opinion as to the fairness, from a financial point of
view, of the Merger Consideration to be received by the holders of InSight
Common Stock.

   UBS Warburg LLC ("UBS Warburg") has acted as financial advisor to InSight in
connection with the Merger and will receive a fee for its services, a
significant portion of which is contingent upon consummation of the Merger. UBS
Warburg also will receive a fee upon delivery of this opinion. UBS Warburg and
its affiliates in the past have provided, and currently are providing, services
to JWC unrelated to the proposed Merger, for which services UBS Warburg and its
affiliates have received and will receive customary compensation. As you are
aware, UBS Warburg may be participating in the financing of the Merger, and
would receive customary compensation for such services. In the ordinary course
of business, UBS Warburg, its successors and affiliates may trade securities of
InSight and affiliates of Purchaser for their own accounts and accounts of
customers and, accordingly, may at any time hold a long or short position in
such securities.

   Our opinion does not address the underlying business decision of InSight to
effect the Merger and does not constitute a recommendation to any stockholder
of InSight as to how such stockholder should vote on the Merger or with respect
to any matters relating to the Merger. At your direction, we have not been
asked to, nor do we, offer any opinion as to the terms of the Agreement or
related documents or the obligations thereunder, or the form of the Merger. In
rendering this opinion, we have assumed, at your direction, that each of
InSight, Purchaser and Merger Sub will comply with all material covenants and
agreements set forth in, and other material terms of, the Agreement and related
documents and that the Merger will be consummated in accordance with its terms,
without waiver, modification or amendment of any material term, condition or
agreement.

   In arriving at our opinion, we have, among other things: (i) reviewed
current and historical market prices and trading volumes of InSight Common
Stock; (ii) reviewed certain publicly available business and historical
financial information relating to InSight; (iii) reviewed certain internal
financial information and other data relating to the business and financial
prospects of InSight, including estimates and financial forecasts prepared by
the management of InSight, that were provided to or discussed with us by
InSight and not publicly available; (iv) conducted discussions with members of
the senior management of InSight; (v) reviewed publicly available financial and
stock market data with respect to certain companies in lines of business we
believe to be generally comparable to those of InSight; (vi) compared the
financial terms of the Merger with the publicly

                                      II-1

available financial terms of certain other transactions which we believe to be
generally relevant; (vii) reviewed the Agreement; and (viii) conducted such
other financial studies, analyses and investigations, and considered such other
information, as we deemed necessary or appropriate. In connection with our
engagement, we were requested to contact, and we held discussions with, certain
third parties to solicit indications of interest in the possible acquisition of
InSight.

   In connection with our review, with your consent, we have not assumed any
responsibility for independent verification of any of the information provided
to or reviewed by us for the purpose of this opinion and have, with your
consent, relied on such information being complete and accurate in all material
respects. In addition, at your direction, we have not made any independent
evaluation or appraisal of any of the assets or liabilities (contingent or
otherwise) of InSight, nor have we been furnished with any such evaluation or
appraisal. With respect to the financial forecasts and estimates referred to
above, we have assumed, at your direction, that they have been reasonably
prepared on a basis reflecting the best currently available estimates and
judgments of the management of InSight as to the future financial performance
of InSight. Our opinion is necessarily based on economic, monetary, market and
other conditions as in effect on, and the information made available to us as
of, the date of this letter.

   Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Merger Consideration to be received by the holders of InSight
Common Stock is fair, from a financial point of view, to such holders.

                                          Very truly yours,

                                          /s/ UBS Warburg LLC

  No filing with, and no permit, authorization, consent or approval of, any
  Governmental Entity or any other person is necessary for the execution and
  delivery of this Agreement by and on behalf of each of the Stockholders and

  contemplated hereby. None of the execution and delivery of this Agreement
  by and on behalf of each of the Stockholders, the consummation of the

   3. Covenants of the Stockholders. Until the termination of this Agreement in
accordance with Section 8 hereof, the Stockholders agree as follows:

     (a) Voting of Subject Shares. At any meeting of stockholders of the
  Company called to vote upon the approval of the Merger, the Merger
  Agreement and the transactions contemplated therein or at any adjournment
  thereof or in any other circumstances upon which a vote or other approval
  with respect to the Merger, the Merger Agreement and the transactions
  contemplated therein is sought (the "Approval Events"), the Stockholders
  shall vote all of the Subject (other than the Warrants) at the time of such
  meeting or adjournment in favor of the Merger, the adoption by the Company
  of the Merger Agreement and the approval of the terms thereof and each of
  the other transactions contemplated by the Merger Agreement.

     (b) Irrevocable Proxy. The Stockholders hereby grant to and appoint
  Parent (and each officer of Parent designated by Parent) their proxy and
  attorney-in-fact (with full power of substitution) to vote all of the
  Subject Shares as indicated in Section 3(a) above. The Stockholders agree
  that this proxy shall be irrevocable during the term of this Agreement and
  is coupled with an interest sufficient at law to support an irrevocable
  power and given to Parent as an inducement to enter into the Merger
  Agreement; provided that Parent may at any time name any other Person as
  its substituted Proxy to act pursuant hereto, either as to a specific
  matter or as to all matters covered herein. Stockholders agree to take such
  further action or execute such other instruments as may be reasonably
  requested by Parent or Acquisition to effectuate the intent of this
  paragraph (b). The Stockholders hereby revoke any proxy previously granted
  by the Stockholders with respect to the Subject Shares.

     (c) Transfer Restrictions. The Stockholders agree not to (i) sell,
  transfer, pledge, encumber, assign or otherwise dispose of or hypothecate

  similar instrument or to any beneficiaries of the Stockholders
  (collectively, "Transfer")), or enter into any contract, option or other
  arrangement or understanding (including any profit sharing arrangement)
  with respect to the Transfer of, any of the Subject Shares other than
  pursuant to the terms of this Agreement and the Merger Agreement, (ii)
  enter into any voting arrangement or understanding other than this
  Agreement with respect to the Subject Shares, whether by proxy, voting
  agreement or otherwise, or (iii) take any action that could make any of
  their representations or warranties contained herein untrue or incorrect or
  could have the effect of preventing or disabling the Stockholders from
  performing any of their obligations hereunder. The Stockholders further
  agree to take in a timely manner any and all actions (including, without
  limitation, delivering the certificates evidencing the Subject Shares to
  the Company) reasonably necessary for the Company to affix a legend on the
  certificates evidencing the Subject Shares stating that the Subject Shares
  are subject to this Agreement.

     (d) Appraisal Rights. The Stockholders hereby irrevocably waives any and
  all rights which they may have as to appraisal, dissent or any similar or
  related matter with respect to the Merger under Section 262 of the General
  Corporation Law of the State of Delaware or otherwise.

     (e) No Solicitation. The Stockholders shall not, and shall use their
  reasonable best efforts to cause their directors, officers, employees,
  attorneys, accountants or financial advisors or other representatives
  ("Representatives") retained by them not to, directly or indirectly through
  another Person, (i) solicit, initiate or encourage (including by way of
  furnishing 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 Takeover Proposal, or (ii) participate in any
  discussions or negotiations regarding any Takeover Proposal; provided that
  the foregoing shall not limit or prohibit any Representative of the
  Stockholders who is a director of the Company from exercising his or her
  fiduciary duty solely as a director of the Company in a manner consistent

construed to require such Representative, solely in his or her capacity as a
director or officer of the Company, to act or fail to act in any manner
inconsistent with (i) his or her fiduciary duties in such capacity and (ii) the
Merger Agreement. Furthermore, no Representative who is or becomes (during the

  reasonable best efforts to cause its directors, officers, employees,
  attorneys, accountants or financial advisors or other representatives
  ("Representatives") retained by it not to, directly or indirectly through
  another Person, (i) solicit, initiate or encourage (including by way of
  furnishing 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 Takeover Proposal, or (ii) participate in any
  discussions or negotiations regarding any Takeover Proposal; provided that
  the foregoing shall not limit or prohibit any Representative of the
  Stockholder who is a director of the Company from exercising his or her
  fiduciary duty solely as a director of the Company in a manner consistent
  with the terms and conditions set forth in the Merger Agreement.

   4. Conversion of Subject Shares. In connection with the Merger and the
Merger Agreement, the Stockholder hereby agrees to deliver a Type B Conversion
Notice (as defined in the Certificate of Designation with respect to the Series
C Preferred Stock) electing to (subject to the delivery of a Type B Conversion
Notice with respect to the Series B Preferred Stock) convert all of the Series
C Preferred Stock that it owns into 130,722.4 shares of the Series D Preferred
Stock pursuant to the terms thereof prior to the record date established by the
Company in connection with the Approval Event which would permit such
Stockholder to vote all of such shares held by such Stockholder after such
conversion, irrespective of any voting limitations, in favor of the Merger, the
Merger Agreement and the transactions contemplated therein.

   5. Conversion of Series D Preferred Stock. Immediately prior to the
Effective Time, the Stockholder hereby agrees to convert all of the shares of
Series D Preferred Stock then owned by it into shares of Company Common Stock.

   6. Additional Shares. Without limiting the provisions of the Merger
Agreement, in the event (i) of any stock dividend, stock split,
recapitalization, reclassification, combination or exchange of shares of
capital stock of the Company on, of or affecting the Subject Shares or (ii) the
Stockholder becomes the record or beneficial owner of any additional shares of
the capital stock of the Company or other securities entitling the holder
thereof to vote or give consent with respect to the matters set forth in
Section 3(a), then the terms of this Agreement shall apply to the shares of
capital stock or other securities of the Company held by the Stockholder
immediately following the effectiveness of the events described in clause (i)
or the Stockholder becoming the

                                     III-20


record or beneficial owner thereof, as described in clause (ii), as though they
were Subject Shares hereunder. The Stockholder hereby agrees to promptly notify
Parent of the number of any additional shares of capital stock or other voting
securities of the Company acquired, of record or beneficially, by the
Stockholder, if any, after the date hereof and prior to the termination of this
Agreement pursuant to Section 8 hereof.

   7. Officers and Directors. Notwithstanding anything contained to the
contrary in this Agreement, in the event a Representative is a director or
officer of the Company, nothing in this Agreement is intended or shall be
construed to, require such Representative, solely in his or her capacity as a
director or officer of the Company, to act or fail to act in any manner
inconsistent with (i) his or her fiduciary duties in such capacity and (ii) the
Merger Agreement. Furthermore, no Representative who is or becomes (during the
term hereof) a director or officer of the Company makes any agreement or
understanding herein solely in his or her capacity as a director or officer,
and nothing herein will limit or affect, or give rise to any liability of any
Representative solely in such Person's capacity as a director or officer of the
Company.

   8. Termination. Except as set forth in the next sentence, this Agreement
shall terminate, and no party shall have any rights or obligations hereunder
and this Agreement shall become null and void and have no further effect
immediately following the earliest to occur of (x) the Effective Time or (y)
the termination of the Merger Agreement. Nothing in this Section 8 shall
relieve any party of liability for breach of this Agreement.

   9. Contents of Agreement; Parties in Interest, etc. This Agreement and the
agreements referred to or contemplated herein set forth the entire
understanding of the parties hereto with respect to the transactions
contemplated hereby and thereby, and, except as set forth in this Agreement and
such other agreements, there are no representations or warranties, express or
implied, made by any party to this Agreement with respect to the subject matter
of this Agreement. Any and all previous agreements and understandings between
or among the parties regarding the subject matter hereof, whether written or
oral, are superseded by this Agreement and the agreements referred to or
contemplated herein.

   10. Assignment and Binding Effect. Neither this Agreement nor the rights and
obligations hereunder may be assigned by any of the parties hereto without the
prior written consent of the other parties hereto; provided, that Parent and/or
Acquisition may assign its rights and obligations under this Agreement to any
directly or indirectly wholly-owned Subsidiary of Parent, upon written notice
to the Stockholder if the assignee shall assume the obligations of Parent
and/or Acquisition hereunder. Subject to the foregoing, all the terms and
provisions of this Agreement shall be binding upon and inure to the benefit of
and be enforceable by the respective successors and assigns of the parties
hereto.

                            DELAWARE CODE ANNOTATED
                         SECTION 262. APPRAISAL RIGHTS
                             TITLE 8. CORPORATIONS
                       CHAPTER 1. GENERAL CORPORATION LAW
                     SUBCHAPTER IX. MERGER OR CONSOLIDATION
                                     8 DEL.

(a) Any stockholder of a corporation of this State who holds shares of stock on
the date of the making of a demand pursuant to subsection (d) of this section
with respect to such shares, who continuously holds such shares through the
effective date of the merger or consolidation, who has otherwise complied with
subsection (d) of this section and who has neither voted in favor of the merger
or consolidation nor consented thereto in writing pursuant to (S) 228 of this
title shall be entitled to an appraisal by the Court of Chancery of the fair
value of the stockholder's shares of stock under the circumstances described in
subsections (b) and (c) of this section. As used in this section, the word
"stockholder" means a holder of record of stock in a stock corporation and also
a member of record of a nonstock corporation; the words "stock" and "share"
mean and include what is ordinarily meant by those words and also membership or
membership interest of a member of a nonstock corporation; and the words
"depository receipt" mean a receipt or other instrument issued by a depository
representing an interest in one or more shares, or fractions thereof, solely of
stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series
of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to (S) 251 (other than a merger effected pursuant to (S)
251(g) of this title), (S) 252, (S) 254, (S) 257, (S) 258, (S) 263 or (S) 264
of this title:

   (1) Provided, however, that no appraisal rights under this section shall be
available for the shares of any class or series of stock, which stock, or
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did
not require for its approval the vote of the stockholders of the surviving
corporation as provided in subsection (f) of (S) 251 of this title.

   (2) Notwithstanding paragraph (1) of this subsection, appraisal rights under
this section shall be available for the shares of any class or series of stock
of a constituent corporation if the holders thereof are required by the terms
of an agreement of merger or consolidation pursuant to (S)(S) 251, 252, 254,
257, 258, 263 and 264 of this title to accept for such stock anything except:

        a. Shares of stock of the corporation surviving or resulting from
  such merger or consolidation, or depository receipts in respect thereof;

        b. Shares of stock of any other corporation, or depository receipts
  in respect thereof, which shares of stock (or depository receipts in
  respect thereof) or depository receipts at the effective date of the merger
  or consolidation will be either listed on a national securities exchange or
  designated as a national market system security on an interdealer quotation
  system by the National Association of Securities Dealers, Inc. or held of
  record by more than 2,000 holders;

        c. Cash in lieu of fractional shares or fractional depository
  receipts described in the foregoing subparagraphs a. and b. of this
  paragraph; or

                                      IV-1


        d. Any combination of the shares of stock, depository receipts and
  cash in lieu of fractional shares or fractional depository receipts
  described in the foregoing subparagraphs a., b. and c. of this paragraph.

   (3) In the event all of the stock of a subsidiary Delaware corporation party
to a merger effected under (S) 253 of this title is not owned by the parent
corporation immediately prior to the merger, appraisal rights shall be
available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.

(d) Appraisal rights shall be perfected as follows:

   (1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting,
shall notify each of its stockholders who was such on the record date for such
meeting with respect to shares for which appraisal rights are available
pursuant to subsection (b) or (c) hereof that appraisal rights are available
for any or all of the shares of the constituent corporations, and shall include
in such notice a copy of this section. Each stockholder electing to demand the
appraisal of such stockholder's shares shall deliver to the corporation, before
the taking of the vote on the merger or consolidation, a written demand for
appraisal of such stockholder's shares. Such demand will be sufficient if it
reasonably informs the corporation of the identity of the stockholder and that
the stockholder intends thereby to demand the appraisal of such stockholder's
shares. A proxy or vote against the merger or consolidation shall not
constitute such a demand. A stockholder electing to take such action must do so
by a separate written demand as herein provided. Within 10 days after the
effective date of such merger or consolidation, the surviving or resulting
corporation shall notify each stockholder of each constituent corporation who
has complied with this subsection and has not voted in favor of or consented to
the merger or consolidation of the date that the merger or consolidation has
become effective; or

   (2) If the merger or consolidation was approved pursuant to (S) 228 or (S)
253 of this title, each constituent corporation, either before the effective
date of the merger or consolidation or within ten days thereafter, shall notify
each of the holders of any class or series of stock of such constituent
corporation who are entitled to appraisal rights of the approval of the merger
or consolidation and that appraisal rights are available for any or all shares
of such class or series of stock of such constituent corporation, and shall
include in such notice a copy of this section; provided that, if the notice is
given on or after the effective date of the merger or consolidation, such
notice shall be given by the surviving or resulting corporation to all such
holders of any class or series of stock of a constituent corporation that are
entitled to appraisal rights. Such notice may, and, if given on or after the
effective date of the merger or consolidation, shall, also notify such
stockholders of the effective date of the merger or consolidation. Any
stockholder entitled to appraisal rights may, within 20 days after the date of
mailing of such notice, demand in writing from the surviving or resulting
corporation the appraisal of such holder's shares. Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
such holder's shares. If such notice did not notify stockholders of the
effective date of the merger or consolidation, either (i) each such constituent
corporation shall send a second notice before the effective date of the merger
or consolidation notifying each of the holders of any class or series of stock
of such constituent corporation that are entitled to appraisal rights of the
effective date of the merger or consolidation or (ii) the surviving or
resulting corporation shall send such a second notice to all such holders on or
within 10 days after such effective date; provided, however, that if such
second notice is sent more than 20 days following the sending of the first
notice, such second notice need only be sent to each stockholder who is
entitled to appraisal rights and

                                      IV-2


who has demanded appraisal of such holder's shares in accordance with this
subsection. An affidavit of the secretary or assistant secretary or of the
transfer agent of the corporation that is required to give either notice that
such notice has been given shall, in the absence of fraud, be prima facie
evidence of the facts stated therein. For purposes of determining the
stockholders entitled to receive either notice, each constituent corporation
may fix, in advance, a record date that shall be not more than 10 days prior to
the date the notice is given, provided, that if the notice is given on or after
the effective date of the merger or consolidation, the record date shall be
such effective date. If no record date is fixed and the notice is given prior
to the effective date, the record date shall be the close of business on the
day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10
days after such stockholder's written request for such a statement is received
by the surviving or resulting corporation or within 10 days after expiration of
the period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

(f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders
who have complied with this section and who have become entitled to appraisal
rights. The Court may require the stockholders who have demanded an appraisal
for their shares and who hold stock represented by certificates to submit their
certificates of stock to the Register in Chancery for notation thereon of the
pendency of the appraisal proceedings; and if any stockholder fails to comply
with such direction, the Court may dismiss the proceedings as to such
stockholder.

(h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to

                                      IV-3


participate in the appraisal proceeding, the Court may, in its discretion,
permit discovery or other pretrial proceedings and may proceed to trial upon
the appraisal prior to the final determination of the stockholder entitled to
an appraisal. Any stockholder whose name appears on the list filed by the
surviving or resulting corporation pursuant to subsection (f) of this section
and who has submitted such stockholder's certificates of stock to the Register
in Chancery, if such is required, may participate fully in all proceedings
until it is finally determined that such stockholder is not entitled to
appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon
the parties as the Court deems equitable in the circumstances. Upon application
of a stockholder, the Court may order all or a portion of the expenses incurred
by any stockholder in connection with the appraisal proceeding, including,
without limitation, reasonable attorney's fees and the fees and expenses of
experts, to be charged pro rata against the value of all the shares entitled to
an appraisal.

(k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation,
either within 60 days after the effective date of the merger or consolidation
as provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the
Court of Chancery shall be dismissed as to any stockholder without the approval
of the Court, and such approval may be conditioned upon such terms as the Court
deems just.

(l) The shares of the surviving or resulting corporation to which the shares of
such objecting stockholders would have been converted had they assented to the
merger or consolidation shall have the status of authorized and unissued shares
of the surviving or resulting corporation.
