                                                         November 26, 1997     
 
Dear Fellow Stockholders:
 
  You are invited to attend a special meeting of the stockholders of Alliance
Imaging, Inc. ("Alliance") to vote on the Agreement and Plan of Merger dated
as of July 23, 1997, between Alliance and Newport Investment LLC (the
"Investor"), a Delaware limited liability company formed and wholly owned by
certain affiliates of Apollo Management, L.P. (such affiliates and the
Investor are collectively referred to as "Apollo"), as amended by Amendment
No. 1 dated as of August 13, 1997, Amendment No. 2 dated as of October 13,
1997 and Amendment No. 3 dated as of November 10, 1997 (the "Recapitalization
Merger Agreement"). The Recapitalization Merger Agreement provides for, among
other things, (1) the merger of Newport Acquisition Corp. ("Newco"), a
corporation to be formed solely for the purpose of this transaction and wholly
owned by the Investor, with and into Alliance (the "Recapitalization"), as a
result of which the shares of common stock of Newco will be converted into
3,632,222 shares of common stock of Alliance (the "Alliance Common Stock"), an
aggregate of 411,358 shares of Alliance Common Stock will be retained by
Alliance's existing stockholders and the balance of the outstanding shares of
Alliance Common Stock (other than shares of Alliance Common Stock held by
Alliance's stockholders, if any, who dissent from the Recapitalization and
comply with all of the provisions of the Delaware General Corporation Law
concerning the right of stockholders to seek appraisal of their shares
("Dissenting Shares")) will be converted into the right to receive $11.00 per
share in cash, (2) the Investor to purchase 150,000 shares of Alliance's non-
voting redeemable Series F preferred stock (the "Series F Preferred Stock"),
(3) the Board of Directors of Newco to become the Board of Directors of
Alliance upon the consummation of the Recapitalization and (4) the amendment
and restatement of Alliance's Restated Certificate of Incorporation. A copy of
the Recapitalization Merger Agreement is attached as Annex A to the enclosed
Proxy Statement/Prospectus.
 
  If the Recapitalization Merger Agreement is approved by holders of a
majority of the shares of Alliance Common Stock, then at the effective time of
the Recapitalization, the separate corporate existence of Newco will cease,
Alliance will continue as the surviving corporation, and 411,358 shares of
Alliance Common Stock, or approximately 3% of the presently issued and
outstanding shares of Alliance Common Stock (assuming conversion of all shares
of preferred stock of Alliance) will be retained by Alliance's existing
stockholders and the remainder, approximately 97% of the presently issued and
outstanding shares (assuming conversion of all shares of preferred stock of
Alliance and assuming there are no Dissenting Shares), will be converted into
the right to receive $11.00 per share in cash. If stockholders of Alliance
entitled to vote at the special meeting elect in the aggregate to retain more
or less than 411,358 shares of Alliance Common Stock, the number of shares to
be retained will be prorated among holders. Consequently, at the time
stockholders of Alliance vote in respect of the Recapitalization Merger
Agreement and decide whether to elect to retain shares of Alliance Common
Stock, they will not know if they will be entitled to retain all of the shares
they elect to retain or if they will be required to retain shares of Alliance
Common Stock which they do not elect to retain.
 
  Pursuant to the Recapitalization Merger Agreement, Apollo will purchase a
total of 3,632,222 shares of Alliance Common Stock and 150,000 shares of
Series F Preferred Stock. Consequently, immediately after the Recapitalization
, Alliance will have 4,043,580 shares of common stock outstanding, of which
Apollo will own 3,632,222 shares (or approximately 90%) and Alliance's
existing stockholders will own 411,358 shares (or approximately 10%).
Immediately after consummation of the transactions, Apollo intends to sell
242,898 shares of Alliance Common Stock owned by Apollo to BT Capital
Corporation for $11.00 per share (or approximately $2.7 million in the
aggregate) in cash, the amount paid to Alliance's existing stockholders for
shares of Alliance
<PAGE>
 
Common Stock. In addition, options to acquire 524,545 shares of Alliance
Common Stock will be held by or issuable to management of Alliance after
consummation of the Recapitalization.
 
  Pursuant to a stockholder agreement dated as of July 23, 1997 (the
"Stockholder Agreement"), among the Investor and stockholders (the "Principal
Stockholders") owning approximately 54.4% of the issued and outstanding shares
of Alliance Common Stock (approximately 66.0% assuming the conversion or
exercise by the Principal Stockholders of all of their securities which are
convertible into or exercisable for shares of Alliance Common Stock), Apollo
has the right to cause a majority of the outstanding shares of Alliance Common
Stock to be voted in favor of the Recapitalization Merger Agreement and has a
currently exercisable option to acquire all of such shares (which option
terminates, in general, on December 31, 1997 or earlier if the
Recapitalization Merger Agreement is terminated). Apollo intends to cause the
shares of common stock subject to the Stockholder Agreement to be voted in
favor of the Recapitalization Merger Agreement, thereby ensuring the approval
of the Recapitalization Merger Agreement without the vote of any additional
stockholders. The Principal Stockholders will be entitled to participate in
the proration of the retained shares in the same manner as Alliance's other
stockholders, unless the Investor exercises the option (in which case, the
Principal Stockholders would receive cash for their shares and would not be
subject to proration). The Investor has advised the Company that it does not
currently intend to exercise the option, and would do so only if a third party
sought to acquire Alliance prior to consummation of the Recapitalization or
the termination of the Recapitalization Merger Agreement. If the Investor does
exercise the option, all 411,358 of the retained shares would be prorated
among Alliance's existing public stockholders, who own approximately 34% of
the issued and outstanding shares of Alliance Common Stock (assuming the
conversion or exercise by the Principal Stockholders of all of their
securities which are convertible into or exercisable for shares of Alliance
Common Stock). Except as described in this paragraph, Apollo currently does
not have any interest in any shares of Alliance Common Stock.
 
  The Recapitalization Merger Agreement contains various conditions, including
the receipt of the necessary stockholder approval and financing, the Investor
having received advice from Ernst & Young LLP that the Recapitalization
qualifies for recapitalization accounting treatment, Alliance having taken
appropriate steps to arrange the payment or prepayment of certain obligations,
the absence of any injunction or other legal restraint or prohibition
preventing the consummation of the Recapitalization and there not having
occurred any material adverse change in respect of Alliance. The
Recapitalization Merger Agreement also contains certain customary conditions
relating to the accuracy of the representations and warranties, the
performance of the covenants and agreements, consents having been obtained or
filings having been made and holders of less than 10% of the outstanding
shares of Alliance Common Stock having validly elected to demand appraisal of
their shares.
 
  THE BOARD OF DIRECTORS OF ALLIANCE HAS UNANIMOUSLY APPROVED THE
RECAPITALIZATION MERGER AGREEMENT AND HAS DETERMINED, AMONG OTHER THINGS, THAT
THE RECAPITALIZATION MERGER AGREEMENT (INCLUDING THE RECAPITALIZATION) IS FAIR
TO AND IN THE BEST INTERESTS OF ALLIANCE'S STOCKHOLDERS, AND RECOMMENDS THAT
ALLIANCE'S STOCKHOLDERS APPROVE THE RECAPITALIZATION MERGER AGREEMENT.
 
  THE BOARD OF DIRECTORS OF ALLIANCE HAS RECEIVED THE WRITTEN OPINION OF
SALOMON BROTHERS INC, DATED AS OF NOVEMBER 10, 1997, THAT, BASED UPON AND
SUBJECT TO THE MATTERS SET FORTH THEREIN, AS OF SUCH DATE, THE CONSIDERATION
TO BE RECEIVED AND RETAINED BY ALLIANCE'S STOCKHOLDERS PURSUANT TO THE
RECAPITALIZATION IS FAIR, FROM A FINANCIAL POINT OF VIEW, TO SUCH
STOCKHOLDERS.
 
                                          Yours very truly,
 
                                          Richard N. Zehner

To the Stockholders of Alliance Imaging, Inc.
   
  NOTICE IS HEREBY GIVEN that a Special Meeting of the stockholders (including
any adjournments or postponements thereof, the "Special Meeting") of Alliance
Imaging, Inc., a Delaware corporation ("Alliance"), will be held at the
offices of Alliance, 1065 North PacifiCenter Drive, Suite 200, Anaheim,
California 92806 on December 17, 1997, at 8:00 a.m., Pacific Time, for the
following purposes, all of which are more fully described in the accompanying
Proxy Statement/Prospectus:     
 
  1. To consider and vote upon a proposal to approve the Agreement and Plan of
Merger dated as of July 23, 1997, between Alliance and Newport Investment LLC
(the "Investor"), a Delaware limited liability company formed and wholly owned
by certain affiliates of Apollo Management, L.P. (such affiliates and the
Investor are collectively referred to as "Apollo"), as amended by Amendment
No. 1 dated as of August 13, 1997, Amendment No. 2 dated as of October 13,
1997 and Amendment No. 3 dated as of November 10, 1997 (the "Recapitalization
Merger Agreement"). A copy of the Recapitalization Merger Agreement is
attached as Annex A to the accompanying Proxy Statement/Prospectus.
 
  2. To transact such other business as may properly come before the Special
Meeting.
 
  The Recapitalization Merger Agreement provides for, among other things, (1)
the merger of Newport Acquisition Corp. ("Newco"), a Delaware corporation to
be formed and wholly owned by the Investor, with and into Alliance (the
"Recapitalization"), as a result of which the shares of common stock of Newco
will be converted into 3,632,222 shares of common stock of Alliance, an
aggregate of 411,358 shares of common stock of Alliance will be retained by
Alliance's existing shareholders and the balance of the outstanding shares of
common stock of Alliance (other than shares of common stock of Alliance held
by Alliance's stockholders, if any, who dissent from the Recapitalization and
comply with all of the provisions of the Delaware General Corporation Law
concerning the right of stockholders to seek appraisal of their shares) will
be converted into the right to receive $11.00 per share in cash, (2) the
Investor to purchase 150,000 shares of Alliance's non-voting redeemable Series
F preferred stock, (3) the Board of Directors of Newco to become the Board of
Directors of Alliance upon the consummation of the Recapitalization and (4)
the amendment and restatement of Alliance's Restated Certificate of
Incorporation.
 
  The affirmative vote of the holders of a majority of the shares of common
stock of Alliance entitled to vote thereon is required to approve the
Recapitalization Merger Agreement. However, pursuant to a stockholder
agreement dated as of July 23, 1997 (the "Stockholder Agreement"), among the
Investor and stockholders (the "Principal Stockholders") owning approximately
54.4% of the issued and outstanding shares of common stock of Alliance
(approximately 66.0% assuming the conversion or exercise by the Principal
Stockholders of all of their securities which are convertible into or
exercisable for shares of common stock of Alliance), Apollo has the right to
cause a majority of the outstanding shares of common stock of Alliance to be
voted in favor of the Recapitalization Merger Agreement and has a currently
exercisable option to acquire all of such shares (which option terminates, in
general, on December 31, 1997 or earlier if the Recapitalization Merger
Agreement is terminated) and, therefore, beneficially owns such shares. Apollo
intends to cause the shares of common stock subject to the Stockholder
Agreement to be voted in favor of the Recapitalization Merger Agreement,
thereby ensuring the approval of the Recapitalization Merger Agreement without
the vote of any additional stockholders. The Principal Stockholders will be
entitled to participate in the proration of the retained shares in the same
manner
<PAGE>
 
as Alliance's other stockholders, unless the Investor exercises the option (in
which case, the Principal Stockholders would receive cash for their shares and
would not be subject to proration). The Investor has advised the Company that
it does not currently intend to exercise the option and would do so only if a
third party sought to acquire Alliance prior to consummation of the
Recapitalization or the termination of the Recapitalization Merger Agreement.
If the Investor does exercise the options, all 411,358 of the retained shares
would be prorated among Alliance's existing public stockholders, who own
approximately 34% of the issued and outstanding shares of common stock of
Alliance (assuming the conversion or exercise by the Principal Stockholders of
all of their securities which are convertible into or exercisable for shares
of common stock of Alliance). Except as described in this paragraph, Apollo
currently does not have any interest in any shares of common stock of
Alliance.
 
  Only common stockholders of record on November 7, 1997 will be entitled to
notice of and to vote at the Special Meeting.
 
  A list of Alliance's stockholders entitled to vote at the Special Meeting
will be available for examination by Alliance's stockholders, for proper
purposes, during normal business hours, at Alliance's corporate offices,
commencing two business days after the date of this Notice of Special Meeting
and continuing through the date of the Special Meeting.
 
                                          BY ORDER OF THE BOARD OF DIRECTORS

                          PROXY STATEMENT/PROSPECTUS
 
                               ----------------
   
  This Proxy Statement/Prospectus (the "Proxy Statement/Prospectus") is being
furnished to stockholders of Alliance Imaging, Inc., a Delaware corporation
("Alliance"), in connection with the solicitation of proxies by the Board of
Directors of Alliance (the "Board of Directors") for use at the Special
Meeting of Alliance's stockholders, including any adjournments or
postponements thereof, scheduled to be held on December 17, 1997 at 8:00 a.m.,
Pacific Time, at the offices of Alliance, 1065 North PacifiCenter Drive, Suite
200, Anaheim, California 92806 (the "Special Meeting"). This Proxy
Statement/Prospectus relates to the Agreement and Plan of Merger dated as of
July 23, 1997, between Alliance and Newport Investment LLC (the "Investor"), a
Delaware limited liability company, as amended by Amendment No. 1 dated as of
August 13, 1997, Amendment No. 2 dated as of October 13, 1997 and Amendment
No. 3 dated as of November 10, 1997 (the "Recapitalization Merger Agreement").
    
  The Investor was formed and is wholly owned by Apollo Investment Fund III,
L.P., a Delaware limited partnership ("AIF III"), Apollo Overseas III, L.P., a
Delaware limited partnership ("Overseas Partners"), and Apollo (U.K.) Partners
III, L.P., a limited partnership organized under the laws of England ("UK
Partners," and together with AIF III, Overseas Partners and the Investor,
"Apollo"), in connection with the Recapitalization. For information concerning
Apollo, see "THE INVESTOR, NEWCO AND APOLLO."
 
  The Recapitalization Merger Agreement provides for, among other things, (1)
the Merger of Newport Acquisition Corp., a corporation to be formed and wholly
owned by the Investor ("Newco"), with and into Alliance (the
"Recapitalization"), as a result of which the shares of common stock of Newco
will be converted into 3,632,222 shares of common stock of Alliance (the
"Alliance Common Stock"), an aggregate of 411,358 shares of Alliance Common
Stock will be retained by Alliance's existing stockholders and the balance of
the outstanding shares of Alliance Common Stock (other than shares of Alliance
Common Stock held by Alliance's stockholders, if any, who dissent from the
Recapitalization and comply with all of the provisions of the Delaware General
Corporation Law (the "DGCL") concerning the right of stockholders to seek
appraisal of their shares ("Dissenting Shares")) will be converted into the
right to receive $11.00 per share in cash (the "Cash Merger Price"), (2) the
Investor to purchase 150,000 shares of Alliance's non-voting redeemable Series
F preferred stock (the "Series F Preferred Stock"), (3) the Board of Directors
of Newco to become the Board of Directors of Alliance upon consummation of the
Recapitalization and (4) the amendment and restatement of Alliance's Restated
Certificate of Incorporation.
 
  If the Recapitalization Merger Agreement is approved by holders of a
majority of the shares of Alliance Common Stock, then at the effective time of
the Recapitalization (the "Recapitalization Effective Time"), the separate
corporate existence of Newco will cease, Alliance will continue as the
surviving corporation, and 411,358 shares of Alliance Common Stock, or
approximately 3% of the presently issued and outstanding shares of Alliance
Common Stock (assuming conversion of all shares of preferred stock of
Alliance), will be retained by Alliance's existing stockholders and the
remainder, approximately 97% of the presently issued and outstanding shares of
Alliance Common Stock (assuming conversion of all shares of preferred stock of
Alliance and assuming there are no Dissenting Shares), will be converted into
the right to receive $11.00 per share in cash. Each stockholder of Alliance
entitled to vote at the Special Meeting may elect to retain shares of Alliance
Common Stock by following the procedures set forth in "THE RECAPITALIZATION--
Proration." If Alliance's stockholders elect to retain more or less than an
aggregate of 411,358 shares of Alliance Common Stock, the number of shares to
be retained will be prorated as described in "THE RECAPITALIZATION--
Proration." Consequently, at the time holders of shares of Alliance Common
Stock vote in respect of the Recapitalization Merger Agreement and decide
whether to elect to retain shares of Alliance Common Stock, they will not know
if they will be entitled to retain all of the shares they elect to retain or
if they will be required to retain shares of Alliance Common Stock which they
do not elect to retain.
 
  Pursuant to the Recapitalization Merger Agreement, Apollo will purchase a
total of 3,632,222 shares of Alliance Common Stock and 150,000 shares of
Series F Preferred Stock. Consequently, immediately after the
Recapitalization, Alliance will have 4,043,580 shares of common stock
outstanding, of which Apollo will own
<PAGE>
 
3,632,222 shares (or approximately 90%) and Alliance's existing stockholders
will own 411,358 shares (or approximately 10%). Immediately after consummation
of the transactions, Apollo intends to sell 242,898 shares of Alliance Common
Stock owned by Apollo to BT Capital Corporation ("BT") for $11.00 per share
(or approximately $2.7 million in the aggregate) in cash, the per share amount
paid to Alliance's existing stockholders for shares of Alliance Common Stock.
The value and marketability of retained shares may change due to the inability
of the existing shareholders to receive a premium if the retained shares are
sold due to the concentration in ownership by Apollo. See "RISK FACTORS--
Possible Delisting; Loss of Liquidity" and "--Control by Apollo." Immediately
after consummation of the Transactions, Apollo also intends to sell to BT
9,000 shares ($0.9 million stated amount) of the Series F Preferred Stock
purchased by it for $0.9 million in cash. In addition, options to acquire
524,545 shares of Alliance Common Stock will be held by or issuable to
management of Alliance after consummation of the Recapitalization. See "THE
RECAPITALIZATION--Interests of Certain Persons in the Recapitalization,"
"CERTAIN RELATED AGREEMENTS--The New Option Plan."
 
  The aggregate cash consideration to be received by Alliance's stockholders
in respect of shares of Alliance Common Stock (other than retained shares)
will be approximately $149.7 million. See "SOURCES AND AMOUNT OF FUNDS."
 
  The affirmative vote of the holders of a majority of the shares of Alliance
Common Stock entitled to vote thereon is required to approve the
Recapitalization Merger Agreement. However, pursuant to a stockholder
agreement dated as of July 23, 1997 (the "Stockholder Agreement"), among the
Investor and stockholders (the "Principal Stockholders") owning approximately
54.4% of the issued and outstanding shares of Alliance Common Stock
(approximately 66.0% assuming the conversion or exercise by the Principal
Stockholders of all of their securities which are convertible into or
exercisable for shares of Alliance Common Stock), Apollo has the right to
cause a majority of the outstanding shares of Alliance Common Stock to be
voted in favor of the Recapitalization Merger Agreement and has a currently
exercisable option to acquire all of such shares (which option terminates, in
general, on December 31, 1997 or earlier if the Recapitalization Merger
Agreement is terminated) and, therefore, beneficially owns such shares. Apollo
intends to cause the shares of Alliance Common Stock subject to the
Stockholder Agreement to be voted in favor of the approval of the
Recapitalization Merger Agreement, thereby ensuring the approval of the
Recapitalization Merger Agreement without the vote of any additional
stockholders. See "THE SPECIAL MEETING--Required Vote." The Principal
Stockholders will be entitled to participate in the proration of the retained
shares in the same manner as Alliance's other stockholders, unless the
Investor exercises the option (in which case, the Principal Stockholders would
receive cash for their shares and would not be subject to proration). The
Investor has advised the Company that it does not currently intend to exercise
the option and would do so only if a third party sought to acquire Alliance
prior to consummation of the Recapitalization or the termination of the
Recapitalization Merger Agreement. If the Investor does exercise the option,
all 411,358 of the retained shares would be prorated among Alliance's existing
public stockholders, who own approximately 34% of the issued and outstanding
shares of Alliance Common Stock (assuming the conversion or exercise by the
Principal Stockholders of all of their securities which are convertible into
or exercisable for shares of Alliance Common Stock). Except as provided in
this paragraph, Apollo currently does not have any interest in any shares of
Alliance Common Stock.
 
  As a result of the Stockholder Agreement, Alliance's stockholders lack the
ability to control whether the Recapitalization occurs. The holders of shares
of Alliance Common Stock will be entitled to appraisal rights under Delaware
law in connection with the Recapitalization as described herein. See
"DISSENTING STOCKHOLDERS' RIGHTS."
 
  This Proxy Statement/Prospectus also constitutes a prospectus of Alliance
with respect to the shares of Alliance Common Stock to be retained by
stockholders in the Recapitalization.

STOCKHOLDERS APPROVE THE RECAPITALIZATION MERGER AGREEMENT IS NOT A

                                    SUMMARY
 
  The following is a summary of certain information contained elsewhere in this
Proxy Statement/Prospectus or in the documents incorporated herein by
reference. Reference is made to, and this summary is qualified in its entirety
by, the more detailed information contained elsewhere in this Proxy
Statement/Prospectus and in the documents incorporated by reference herein.
Unless the context otherwise requires, the terms "Alliance" and the "Company"
refer to Alliance Imaging, Inc. and its subsidiaries.
 
THE COMPANY
 
  The Company is a leading nationwide provider of diagnostic imaging services
and the largest operator of state-of-the-art mobile diagnostic imaging systems
and related outsourced radiology services in the United States. The Company
primarily provides magnetic resonance imaging ("MRI") systems and services to
hospitals and other health care providers on a mobile, shared user basis. The
Company also provides dedicated, full-time MRI systems and services as well as
full-service management of imaging operations for selected hospitals. The
Company's services enable small to mid-size hospitals to gain access to
advanced diagnostic imaging technology and related value-added services without
making a substantial investment in equipment and personnel. The Company
operates a fleet of 98 MRI systems and services 356 MRI customers in 36 states
under exclusive contracts with an average remaining length of approximately 24
months as of September 30, 1997. Alliance is a Delaware corporation with its
principal executive offices located at 1065 North PacifiCenter Drive, Suite
200, Anaheim, California 92806. The telephone number of Alliance at such
offices is (714) 688-7100.
 
THE SPECIAL MEETING
   
  Time and Place. The Special Meeting of Alliance's stockholders will be held
at the offices of Alliance, 1065 North PacifiCenter Drive, Suite 200, Anaheim,
California 92806, on December 17, 1997, beginning at 8:00 a.m., Pacific Time
(the "Special Meeting Date").     
 
 
  Record Date; Stock Entitled to Vote; Quorum. Only record holders of Alliance
Common Stock at the close of business on November 7, 1997 (the "Record Date")
will be entitled to receive notice of and to vote at the Special Meeting. The
presence, in person or by proxy, at the Special Meeting of at least a majority
of the votes entitled to be cast at the Special Meeting is necessary to
constitute a quorum for the transaction of business. Abstentions will be
counted as present for the purposes of determining whether a quorum is present
but will not be counted as votes cast in favor of the Recapitalization Merger
Agreement. See "THE SPECIAL MEETING--Record Date; Stock Entitled to Vote;
Quorum."
 
  Matters to be Considered. The purpose of the Special Meeting is to vote on
the Recapitalization Merger Agreement. The Recapitalization Merger Agreement
provides for, among other things, (1) the Recapitalization, (2) the Investor to
purchase 150,000 shares of Series F Preferred Stock, (3) the Board of Directors
of Newco to become the Board of Directors of Alliance upon the consummation of
the Recapitalization and (4) the amendment and restatement of Alliance's
Restated Certificate of Incorporation. See "THE SPECIAL MEETING--Matters to be
Considered."
 
  Required Vote. The affirmative vote of the holders of a majority of the
shares of Alliance Common Stock entitled to vote thereon is required to approve
the Recapitalization Merger Agreement. However, pursuant to the
 
                                       7
<PAGE>
 
Stockholder Agreement, Apollo has the right to cause a majority of the
outstanding shares of Alliance Common Stock to be voted in favor of the
Recapitalization Merger Agreement and has an option to acquire all of such
shares. Apollo intends to cause the shares of Alliance Common Stock subject to
the Stockholder Agreement to be voted in favor of the approval of the
Recapitalization Merger Agreement, thereby ensuring the approval of the
Recapitalization Merger Agreement without the vote of any additional
stockholders. See "THE SPECIAL MEETING --Required Vote" and "CERTAIN RELATED
AGREEMENTS--Stockholder Agreement."
 
  Voting; Revocation of Proxies. Shares of Alliance Common Stock represented by
all properly executed Proxies received in time for the Special Meeting (and not
properly revoked) will be voted in the manner specified in such Proxies.
Proxies that do not contain any instruction to vote for or against or to
abstain from voting on a particular matter will be voted in favor of such
matter.
 
  Any Proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before the shares represented by such Proxy are voted at
the Special Meeting by (1) attending and voting in person at the Special
Meeting, (2) giving notice of revocation of the Proxy at the Special Meeting or
(3) delivering to the Secretary of Alliance (a) a written notice of revocation
or (b) a duly executed Proxy relating to the same shares and matters to be
considered at the Special Meeting, bearing a date later than the Proxy
previously executed. Attendance at the Special Meeting will not in and of
itself constitute a revocation of a Proxy.
 
  If the Special Meeting is adjourned, for whatever reason, the approval of the
matters to be considered at the Special Meeting shall be considered and voted
upon by stockholders at the subsequent, reconvened meeting, if any. See "THE
SPECIAL MEETING--Voting; Revocation of Proxies."
 
  Solicitation of Proxies. The cost of soliciting Proxies will be borne by
Alliance. Alliance may solicit Proxies and Alliance's directors, officers and
employees may also solicit Proxies by telephone, telegram or personal
interview. These persons will receive no additional compensation for their
services. Arrangements will be made to furnish copies of proxy materials to
fiduciaries, custodians and brokerage houses for forwarding to beneficial
owners of Alliance Common Stock. Such persons will be reimbursed for reasonable
out-of-pocket expenses. See "THE SPECIAL MEETING--Solicitation of Proxies."
EXCEPT FOR CERTIFICATES REPRESENTING ALLIANCE COMMON STOCK SURRENDERED WITH AN
ELECTION FORM AS DESCRIBED IN THE ACCOMPANYING PROXY STATEMENT/PROSPECTUS UNDER
"THE SPECIAL MEETING--PROCEDURE FOR RETAINED SHARE ELECTION," ALLIANCE'S
STOCKHOLDERS SHOULD NOT FORWARD STOCK CERTIFICATES TO THE EXCHANGE AGENT UNTIL
THEY HAVE RECEIVED THE LETTER OF TRANSMITTAL.
 
  Dissenters' Rights. Under Section 262 of the DGCL, any stockholder of
Alliance may dissent from the Recapitalization and seek to obtain payment for
the fair value of such stockholder's shares of Alliance Common Stock. In order
to dissent, (i) the dissenting stockholder must deliver to Alliance, prior to
the vote being taken on the Recapitalization Merger Agreement and the
Recapitalization at the Special Meeting, a written demand for appraisal of such
stockholder's shares of Alliance Common Stock and (ii) the dissenting
stockholder must not vote in favor of the Recapitalization Merger Agreement.
See "DISSENTING STOCKHOLDERS' RIGHTS."
 
  Recommendation of the Board of Directors. The Board of Directors of Alliance
has unanimously approved the Recapitalization Merger Agreement and has
determined, among other things, that the Recapitalization Merger Agreement is
fair to and in the best interests of Alliance's stockholders, and recommends
that Alliance's stockholders approve the Recapitalization Merger Agreement. See
"THE SPECIAL MEETING--Matters to be Considered" and "THE RECAPITALIZATION--
Recommendation of the Board of Directors; Reasons for the Recapitalization."
 
  The recommendation by the Board of Directors of Alliance that Alliance's
stockholders approve the Recapitalization Merger Agreement is not a
recommendation as to whether stockholders should retain shares of Alliance
Common Stock.
 
  Interests of Certain Persons in the Recapitalization. In considering the
recommendation of the Board of Directors with respect to the Recapitalization
Merger Agreement, stockholders should be aware that certain
 
                                       8
<PAGE>
 
members of management of Alliance at the time of the Board of Director's
approval of the Recapitalization Merger Agreement had, and currently have,
certain interests which may present them with potential conflicts of interest
in connection with the Recapitalization. Although all Alliance stockholders
will participate in the Recapitalization on the same basis (assuming the option
granted pursuant to the Stockholder Agreement is not exercised), the
Recapitalization will cause the acceleration of substantially all of the
outstanding unvested stock options held by management and members of the Board
of Directors of Alliance. Certain members of management will retain certain
options to acquire 70,000 shares of Alliance Common Stock, which options have
an approximate aggregate value of $0.5 million. The Recapitalization will also
cause the acceleration of certain long-term incentive payments previously
earned by management in the approximate aggregate amount of $2.1 million, and
will trigger "change of control" payments of approximately $1.8 million
pursuant to the employment agreements with certain members of management. In
addition, Alliance has entered into employment agreements, each dated as of
July 23, 1997, with Richard N. Zehner to act as Chief Executive Officer and
with Vincent S. Pino to act as Chief Operating Officer (the "Employment
Agreements"), in each case, to be effective upon consummation of the
Recapitalization, and the Investor has entered into an agreement with Messrs.
Zehner and Pino that contains, among other things, covenants not to compete
with Alliance. The Board of Directors was aware of these interests and
considered them in addition to the other matters described under "THE
RECAPITALIZATION--Background of the Recapitalization" and "THE
RECAPITALIZATION--Recommendation of the Board of Directors; Reasons for the
Recapitalization." See "THE RECAPITALIZATION--Interests of Certain Persons in
the Recapitalization" and "CERTAIN RELATED AGREEMENTS--Employment Agreements
and Agreement Not to Compete."
 
  Opinion of Financial Advisor. Salomon Brothers Inc ("Salomon Brothers") was
retained as financial advisor to Alliance and has delivered to the Board of
Directors its written opinion dated as of November 10, 1997, that, based upon
and subject to the matters set forth therein, as of such date, the
consideration to be received and retained by holders of shares of Alliance
Common Stock in the proposed Recapitalization is fair, from a financial point
of view, to such stockholders. Alliance will pay Salomon Brothers the following
fees for these services: (a) $100,000, which was earned upon Alliance's
execution of the Recapitalization Merger Agreement, plus (b) an additional fee
of $400,000, which was earned upon the initial submission of the Salomon
Brothers' fairness opinion to the Board of Directors of Alliance on July 22,
1997, plus (c) an additional fee of approximately $2.4 million, which is
contingent upon the consummation of the Recapitalization. See "THE
RECAPITALIZATION--Opinion of the Financial Advisor."
 
  A copy of the opinion of Salomon Brothers, which sets forth the assumptions
made, procedures followed, matters considered and scope of review, is attached
to this Proxy Statement/Prospectus as Annex C and should be read carefully in
its entirety. See "THE RECAPITALIZATION--Opinion of Financial Advisor," which
contains a summary of the fairness opinion, the analyses underlying the
fairness opinion and a discussion of the fees to be paid to Salomon Brothers
and the conditions under which such fees are payable. The amount of
consideration payable in the Recapitalization was the result of arm's length
negotiations between the Investor and Alliance, in consultation with their
respective financial advisors and other representatives, and was not
established by Salomon Brothers. See "THE RECAPITALIZATION--Opinion of the
Financial Advisor."
 
THE RECAPITALIZATION
 
  Reasons for the Recapitalization. The Board of Directors of Alliance has
unanimously approved the Recapitalization Merger Agreement and has determined,
among other things, that the Recapitalization Merger Agreement is fair to and
in the best interests of Alliance's stockholders, and recommends that
Alliance's stockholders approve the Recapitalization Merger Agreement, because
of, among other things, the following factors: a balancing of the risks and
benefits of the Recapitalization against the risks and benefits of the other
strategic alternatives available to Alliance, including continuing as an
independent entity; the consideration to be paid and retained in the
Recapitalization, valued at $11.00 per share of Alliance Common Stock,
represents a premium for Alliance Common Stock, compared to its historical
price levels; the written opinion of Salomon Brothers with respect to the
fairness of the consideration to be received and retained by Alliance's
stockholders
 
                                       9

in the Recapitalization; the terms and conditions of the Recapitalization
Merger Agreement; the fees and expenses to be paid to an affiliate of Apollo;
the terms and conditions of the Stockholder Agreement; and that the proposed
structure of the Recapitalization treats all stockholders equally by giving all
stockholders the opportunity to receive cash for their shares or to retain
shares of Alliance Common Stock (subject in each case to proration). See "THE
RECAPITALIZATION--Recommendation of the Board of Directors; Reasons for the
Recapitalization."
 
  Effect of the Recapitalization. Pursuant to the Recapitalization Merger
Agreement, Newco will be merged with and into Alliance. At the Recapitalization
Effective Time, the separate corporate existence of Newco will cease, Alliance
will continue as the surviving corporation, the shares of common stock of Newco
will be converted into 3,632,222 shares of Alliance Common Stock, 411,358
shares of outstanding Alliance Common Stock will be retained by Alliance's
existing shareholders and the balance of the shares of Alliance Common Stock
issued and outstanding immediately prior to the Recapitalization Effective Time
(other than Dissenting Shares) will be converted into the right to receive
$11.00 in cash.
 
  If the Recapitalization Merger Agreement is approved by holders of a majority
of the shares of Alliance Common Stock, then 411,358 shares of Alliance Common
Stock, or approximately 3% of the presently issued and outstanding shares of
Alliance Common Stock (assuming the conversion of all outstanding shares of
preferred stock of Alliance), will be retained by Alliance's existing
stockholders and the remainder, approximately 97% of the presently issued and
outstanding shares of Alliance Common Stock (assuming the conversion of all
outstanding shares of preferred stock of Alliance and assuming there are no
Dissenting Shares) will be converted into the right to receive $11.00 per share
in cash. Each stockholder of Alliance may elect to retain shares of Alliance
Common Stock by following the procedures set forth in "THE RECAPITALIZATION--
Proration." If Alliance's stockholders elect in the aggregate to retain more or
less than 411,358 shares of Alliance Common Stock, the number of shares to be
retained will be prorated as described in "THE RECAPITALIZATION--Proration."
Consequently, at the time holders of shares of Alliance Common Stock vote in
respect of the Recapitalization Merger Agreement and decide whether to elect to
retain shares of Alliance Common Stock, they will not know if they will be
entitled to retain all of the shares they elect to retain or if they will be
required to retain shares of Alliance Common Stock which they do not elect to
retain. The Principal Stockholders will be entitled to participate in the
proration of the retained shares in the same manner as Alliance's other
stockholders, unless the Investor exercises the option (in which case, the
Principal Stockholders would receive cash for their shares and would not be
subject to proration). The Investor has advised the Company that it does not
currently intend to exercise the option and would do so only if a third party
sought to acquire Alliance prior to consummation of the Recapitalization or the
termination of the Recapitalization Merger Agreement. If the Investor does
exercise the option, all 411,358 of the retained shares would be prorated among
Alliance's existing public stockholders, who own approximately 34% of the
issued and outstanding shares of Alliance Common Stock (assuming the conversion
or exercise by the Principal Stockholders of all of their securities which are
convertible into or exercisable for shares of Alliance Common Stock. See "THE
RECAPITALIZATION--Merger Consideration."
 
  Pursuant to the Recapitalization Merger Agreement, Apollo will receive a
total of 3,632,222 shares of Alliance Common Stock and 150,000 shares of Series
F Preferred Stock. Consequently, immediately after the Recapitalization,
Alliance will have 4,043,580 common shares outstanding, of which Apollo will
own 3,632,222 shares (or approximately 90%) and Alliance's existing
stockholders will own 411,358 shares (or approximately 10%). Immediately after
consummation of the Recapitalization, Apollo intends to sell to BT (i) 242,898
shares of Alliance Common Stock owned by Apollo for $11.00 per share (or
approximately $2.7 million in the aggregate) in cash, the per share amount paid
to Alliance's existing stockholders for their shares of Alliance Common Stock
and (ii) 9,000 shares ($0.9 million stated amount) of the Series F Preferred
Stock purchased by Apollo for $0.9 million in cash. In addition, options to
acquire 524,545 shares of Alliance Common Stock will be held by or issuable to
management of Alliance after consummation of the Recapitalization. See "THE
RECAPITALIZATION--Interests of Certain Persons in the Recapitalization,"
"CERTAIN RELATED AGREEMENTS--The New Option Plan."
 
                                       10

  There is no valuation difference between a share of Alliance Common Stock
that is to be converted into the right to receive the Cash Merger Price and a
share of Alliance Common Stock that is to be retained. As of the consummation
of the Recapitalization, each share of Alliance Common Stock has an implied
value of $11.00. However, following consummation of the Recapitalization, the
value of the retained shares will be subject to change and there can be no
assurance that the value of the retained shares will not materially decrease
following the consummation of the Recapitalization. See "RISK FACTORS--Possible
Delisting; Loss of Liquidity."
 
  Procedure for Retained Share Election. Each person who is a record holder of
shares of Alliance Common Stock at the close of business on the Record Date
will be entitled, with respect to all or any portion of his or its shares of
Alliance Common Stock (the "Elected Retained Shares"), to make an election to
retain such shares as set forth herein, and subject to the provisions relating
to proration as set forth herein (the "Retained Share Election").
 
  A Retained Share Election shall have been validly made only if American Stock
Transfer & Trust Company (the "Exchange Agent") shall have received, on or
prior to the Special Meeting Date, the form for making such election (the
"Election Form"), properly completed and signed in accordance with such rules
as the Exchange Agent may establish pursuant to the Recapitalization Merger
Agreement, and accompanied by either (i) certificates for the shares of
Alliance Common Stock to which such Election Form relates, duly endorsed in
blank or otherwise in form acceptable for transfer on the books of Alliance, or
(ii) an appropriate guarantee of delivery of such certificates as set forth in
such Election Form from a firm which is a member of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
or from a commercial bank or trust company having an office or correspondent in
the United States (a "Notice of Guaranteed Delivery"). See "THE
RECAPITALIZATION--Procedure for Retained Share Election."
 
  Proration. Pursuant to the Recapitalization Merger Agreement, if the
aggregate number of Elected Retained Shares (the "Elected Retained Share
Number") exceeds 411,358 (the "Actual Retained Share Number"), then the number
of shares of Alliance Common Stock that will be retained will be reduced by
such excess number of shares (each such share included among such excess, a
"Non-Elected Cash Share"). In such event, each holder of Elected Retained
Shares shall be allocated Non-Elected Cash Shares in lieu of Elected Retained
Shares such that (after giving effect to adjustments for fractional shares)
each such holder shall be deemed to hold Non-Elected Cash Shares in an amount
equal to (x) the total number of Elected Retained Shares held by such holder
less (y) the product of (A) a fraction, the numerator of which is the Actual
Retained Share Number and the denominator of which is the Elected Retained
Share Number, multiplied by (B) the total number of Elected Retained Shares
held by such holder. For example, if Alliance's existing stockholders elected
in the aggregate to retain a number of shares of Alliance Common Stock which is
twice as great as the Actual Retained Share Number, each stockholder would be
allowed to retain only one-half of the number of shares of Alliance Common
Stock which such stockholder elected to retain.
 
  Pursuant to the Recapitalization Merger Agreement, if the Actual Retained
Share Number is greater than the Elected Retained Share Number, then the
aggregate number of shares of Alliance Common Stock which shall be converted
into the right to receive cash shall be decreased by a number of shares equal
to the excess of the Actual Retained Share Number over the Elected Retained
Share Number (each share included among such excess, a "Non-Elected Retained
Share"). In such event, each holder of Elected Cash Shares (other than the
Investor) shall be allocated a portion of the Non-Elected Retained Shares in
lieu of Elected Cash Shares (after giving effect to adjustments for fractional
shares) equal to (i) the number of Elected Cash Shares held by such holder,
multiplied by (ii) a fraction, the numerator of which is the number of Non-
Elected Retained Shares and the denominator of which is the aggregate number of
Elected Cash Shares held by all holders (other than the Investor). For example,
if Alliance's existing stockholders elected in the aggregate to retain 311,358
shares of Alliance Common Stock (i.e., 100,000 less than the Actual Retained
Share Number), each stockholder would retain all of the shares of Alliance
Common Stock which such stockholder had elected to retain plus such
stockholder's portion of the 100,000 additional shares of Alliance Common Stock
required to be retained by Alliance's stockholders, which additional shares
would be allocated among stockholders in proportion to the
 
                                       11
<PAGE>
 
number of shares of Alliance Common Stock each stockholder had requested be
converted into the right to receive cash. If none of Alliance's existing
stockholders made a Retained Share Election, a holder of 100 shares of Alliance
Common Stock would be entitled to receive $1,078 in cash (98 shares at $11.00
per share) and would retain 2 shares of Alliance Common Stock. See "THE
RECAPITALIZATION--Proration."
 
  The Principal Stockholders will be entitled to participate in the proration
of the retained shares in the same manner as Alliance's other stockholders,
unless the Investor exercises the option (in which case, the Principal
Stockholders would receive cash for their shares and would not be subject to
proration). The Investor has advised the Company that it does not currently
intend to exercise the option and would do so only if a third party sought to
acquire Alliance prior to consummation of the Recapitalization or the
termination of the Recapitalization Merger Agreement. If the Investor does
exercise the option, all 411,358 of the retained shares would be prorated among
Alliance's existing public stockholders, who own approximately 34% of the
issued and outstanding shares of Alliance Common Stock (assuming the conversion
or exercise by the Principal Stockholders of all of their securities which are
convertible into or exercisable for shares of Alliance Common Stock).
 
  Retention of Shares; Procedures for Exchanging Certificates. The retention of
shares of Alliance Common Stock or the conversion of shares of Alliance Common
Stock into the right to receive cash (other than shares as to which dissenters'
rights are properly exercised) pursuant to the Recapitalization will occur, in
each case, at the Recapitalization Effective Time.
 
  As soon as practicable after the Recapitalization Effective Time, the
Exchange Agent will send a letter of transmittal to each holder of Alliance
Common Stock. The letter of transmittal will contain instructions with respect
to the surrender of certificates representing shares of Alliance Common Stock
in exchange for cash and, under certain circumstances, certificates
representing shares of Alliance Common Stock to be retained in the
Recapitalization and the amount of cash in lieu of any fractional interest in a
share of Alliance Common Stock for which the shares represented by the
certificates so surrendered are exchangeable pursuant to the Recapitalization
Merger Agreement.
 
  As soon as practicable after the Recapitalization Effective Time, each holder
of an outstanding certificate or certificates at such time which prior thereto
represented shares of Alliance Common Stock shall, upon surrender to the
Exchange Agent of such certificate or certificates and acceptance thereof by
the Exchange Agent, be entitled to the amount of cash, if any, into which the
number of shares of Alliance Common Stock previously represented by such
certificate or certificates surrendered shall have been converted pursuant to
the Recapitalization Merger Agreement and a certificate or certificates
representing the number of full shares of Alliance Common Stock, if any, to be
retained by the holder thereof pursuant to the Recapitalization Merger
Agreement.
 
  After the Recapitalization Effective Time, there will be no further transfer
on the records of Alliance or its transfer agent of certificates representing
shares of Alliance Common Stock which have been converted, in whole or in part,
pursuant to the Recapitalization Merger Agreement into the right to receive
cash, and if such certificates are presented to Alliance for transfer, they
will be canceled against delivery of cash and, if appropriate, certificates for
retained shares of Alliance Common Stock.
 
  No dividends or other distributions with a record date after the
Recapitalization Effective Time will be paid with respect to any shares of
retained Alliance Common Stock represented by any unsurrendered certificate,
and no cash payment in lieu of fractional shares will be paid to any such
holder pursuant to the Recapitalization Merger Agreement, until the surrender
of such certificate in accordance with the Recapitalization Merger Agreement.
See "THE RECAPITALIZATION--Retention of Shares; Procedures for Exchanging
Certificates."
 
  Conduct of Business Pending the Recapitalization. Pursuant to the
Recapitalization Merger Agreement, Alliance has agreed to carry on its business
and that of its subsidiaries prior to the Recapitalization Effective Time in
the ordinary course of business consistent with past practice. See "THE
RECAPITALIZATION--Conduct of Business Pending the Recapitalization."
 
                                       12
<PAGE>
 
 
  Conditions to the Consummation of the Recapitalization. The Recapitalization
Merger Agreement contains various conditions, including the receipt of the
necessary stockholder approval and financing, the Investor having received
advice from Ernst & Young LLP that the Recapitalization qualifies for
recapitalization accounting treatment, Alliance having taken appropriate steps
to arrange the payment or prepayment of certain obligations, the expiration or
termination of the waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), which waiting period has
expired, the absence of any injunction or other legal restraint or prohibition
preventing the consummation of the Recapitalization and there not having
occurred any material adverse change in respect of Alliance. The
Recapitalization Merger Agreement also contains certain customary conditions
relating to the accuracy of the representations and warranties, the performance
of the covenants and agreements, consents having been obtained or filings
having been made and holders of less than 10% of the outstanding shares of
Alliance Common Stock having validly elected to demand appraisal of their
shares. Subject to applicable law, each of the conditions, other than the
condition requiring stockholder approval, may be waived. Alliance does not
intend to resolicit a vote of its stockholders on the Recapitalization Merger
Agreement in the event any material conditions are waived, unless such waiver
results in a fundamental change in the Recapitalization (including a material
change in accounting or tax treatment), in which event Alliance has undertaken
to resolicit the vote of its shareholders and would amend this Proxy
Statement/Prospectus. However, the Investor has agreed, pursuant to the
Stockholder Agreement, not to waive any condition so as to reduce the value of
the consideration payable in the Recapitalization, materially adversely affect
the timing of the closing of the Recapitalization, reduce the Cash Merger Price
or otherwise adversely affect the interests of the Principal Stockholders. See
"THE RECAPITALIZATION--Conditions to the Consummation of the Recapitalization."
 
  Possible Delisting; Termination of SEC Reporting. Following the consummation
of the Recapitalization, Alliance may be required to or may seek to have the
Alliance Common Stock, which is currently traded on the Nasdaq SmallCap Market,
delisted and may deregister under the Exchange Act. Any delisting of Alliance
Common Stock, together with the substantial decrease in the number of shares of
Alliance Common Stock to be held by holders thereof other than the Investor, is
expected to result in a substantial decrease in the liquidity of Alliance
Common Stock, even if the Company continues to be a reporting company under the
Exchange Act and continues to file the periodic reports (including annual and
quarterly reports) required to be filed thereunder. If the Company ceases to be
a reporting company under the Exchange Act, the Company does not plan to
provide any reports or information to public stockholders other than pursuant
to the right of such stockholders to inspect the books and records of the
Company as required by the DGCL. As a result, the information available to
stockholders on the business and financial condition of the Company would be
reduced, which could have a material adverse effect on the value of the
Alliance Common Stock. See "RISK FACTORS--Possible Delisting; Loss of
Liquidity" and "RISK FACTORS--Termination of SEC Reporting."
 
  Resale of Alliance Common Stock following the Recapitalization. Alliance
Common Stock to be retained in connection with the Recapitalization will be
freely transferable, except that shares retained by any stockholder who is an
"affiliate" (as defined under the Securities Act and generally including,
without limitation, directors, executive officers and beneficial owners of 10%
or more of a class of capital stock) of Alliance for purposes of Rule 145 under
the Securities Act will not be transferable except pursuant to an effective
registration statement or an exemption from the registration requirements of
the Securities Act. This Proxy Statement/Prospectus does not cover sales of
Alliance Common Stock retained by any person who is an affiliate of Alliance.
See "THE RECAPITALIZATION--Resale of Alliance Common Stock Following the
Recapitalization."
 
  Treatment of Alliance Stock Options and Warrants. Substantially all of the
options to purchase Alliance Common Stock under Alliance's 1991 Amended and
Restated Stock Option Plan shall vest and become exercisable as a result of the
Recapitalization. Except as noted below, all outstanding options and warrants
to purchase Alliance Common Stock shall be cancelled at the Recapitalization
Effective Time and Alliance shall pay the holder thereof an amount equal to the
number of shares of Alliance Common Stock subject to the option or warrant
times the excess of the Cash Merger Price over the exercise price of the
warrant or option. Such
 
                                       13
<PAGE>
 
options are held by management and other Alliance employees, and substantially
all of such warrants are held by certain of Alliance's current and former
institutional lenders. The total value of the options and warrants to be paid
is approximately $9.9 million and $2.1 million, respectively. Notwithstanding
the foregoing, options to purchase 70,000 shares of Alliance Common Stock held
by members of Alliance's management will remain outstanding following the
Recapitalization Effective Time. See "THE RECAPITALIZATION--Interests of
Certain Persons in the Recapitalization"; "--Effect on Warrants and Alliance
Stock Options."
 
  Certain Tax Consequences of the Recapitalization. For U.S. federal income tax
purposes, Newco will be disregarded as a transitory entity, and the merger of
Newco with and into Alliance will be treated, with respect to cash received in
exchange for shares of Alliance Common Stock, as a sale of a portion of such
Alliance Common Stock to the Investor and as a redemption of a portion of such
Alliance Common Stock by Alliance. There will be no gain or loss recognized for
U.S. federal income tax purposes with the respect to shares of Alliance Common
Stock retained by a stockholder. However, under certain circumstances, a
stockholder that actually retains some, but not all, of such stockholder's
shares of Alliance Common Stock may be required to treat the receipt of a
portion of the cash received in the Recapitalization as the receipt of a
dividend (rather than as the receipt of proceeds from the sale of the shares of
Alliance Common Stock, which would generally receive capital gain treatment).
Alliance has received an opinion from Irell & Manella LLP regarding certain
federal income tax consequences of the Recapitalization. See "THE
RECAPITALIZATION--Certain Tax Consequences of the Recapitalization."
 
  Termination of the Recapitalization Merger Agreement. The Recapitalization
Merger Agreement provides that it may be terminated in certain circumstances at
any time prior to the Recapitalization Effective Time, whether before or after
approval of the Recapitalization Merger Agreement and the Recapitalization by
the stockholders of Alliance. See "CERTAIN PROVISIONS OF THE RECAPITALIZATION
MERGER AGREEMENT."
 
  Certain Related Agreements. Agreements related to the Recapitalization
include, among other agreements, the Stockholder Agreement, two Employment
Agreements, Covenants Not to Compete and the New Option Plan (each as defined
herein). See "CERTAIN RELATED AGREEMENTS."
 
SOURCES AND AMOUNT OF FUNDS
 
  Approximately $270 million will be required to finance the Recapitalization,
to refinance certain existing indebtedness of Alliance (the "Refinancings"), to
pay the fees and expenses in connection with the foregoing and to provide for
the Company's working capital.
 
  In connection with the Recapitalization, the Refinancing and the payment of
related fees and expenses, the Company intends to (i) enter into an agreement
(the "Credit Agreement") consisting of a $75 million revolving loan facility
(the "Revolving Loan Facility") and a $50 million term loan facility (the "Term
Loan Facility"), pursuant to which it will borrow approximately $50 million and
(ii) issue approximately $165 million aggregate principal amount of its Senior
Subordinated Notes due 2005 (the "Notes") in a public offering registered under
the Securities Act (the "Offering"). Immediately following consummation of the
Recapitalization, it is expected that the Company will have approximately $75
million of availability under the Revolving Loan Facility, which will be
available for the Company's working capital requirements and to finance
acquisitions.
 
  Apollo's investment (the "New Equity Investment") in Alliance after the
Recapitalization Effective Time will consist of a cash contribution to the
Investor in an aggregate amount of approximately $55.0 million, which the
Investor intends to contribute to the Company at the Recapitalization Effective
Time, at which time the New Equity Investment will be available to the Company.
The total investment in Alliance after the Recapitalization Effective Time will
be $60 million, consisting of (1) $40.5 million of Alliance Common Stock
(consisting of approximately $40.0 million contributed by Apollo and continuing
options held by Alliance management having
 
                                       14
<PAGE>
 
a net option value of approximately $0.5 million), (2) $4.5 million implied
value of the shares of Alliance Common Stock to be retained by Alliance's
existing stockholders and (3) $15 million of Alliance's Series F Preferred
Stock. See "SOURCES AND AMOUNTS OF FUNDS." Immediately after consummation of
the Transactions, Apollo intends to sell to BT $0.9 million stated amount of
the Series F Preferred Stock purchased by it for $0.9 million in cash.
 
  The Recapitalization, the Refinancings, the borrowings under the Credit
Agreement as of the Recapitalization Effective Time, the Offering and the New
Equity Investment are collectively referred to as the "Transactions."
 
  Pursuant to the Recapitalization Merger Agreement, Apollo will receive a
total of 3,632,222 shares of Alliance Common Stock. Consequently, immediately
after the Recapitalization Alliance will have 4,043,580 shares of Alliance
Common Stock outstanding, of which Apollo will own 3,632,222 shares (or
approximately 90%) and Alliance's existing stockholders will own 411,358 shares
(or approximately 10%). Immediately after consummation of the Recapitalization,
Apollo intends to sell 242,898 shares of Alliance Common Stock owned by Apollo
to BT Capital Corporation for $11.00 per share (or approximately $2.7 million
in the aggregate) in cash, the amount paid to Alliance's existing stockholders
for their shares of Alliance Common Stock. In addition, options to acquire
524,545 shares of Alliance Common Stock will be held by or issuable to
management of Alliance after consummation of the Recapitalization. See "THE
RECAPITALIZATION--Interests of Certain Persons in the Recapitalization,"
"CERTAIN RELATED AGREEMENTS--The New Option Plan."
 
  The consummation of the Transactions will be concurrent. The approximate
sources and amount of funds in connection with the Transactions are presented
in the following table, assuming the Transactions occurred as of September 30,
1997 (dollars in millions):

conditions, including the financing condition, under the Recapitalization
Merger Agreement. However, there can be no assurance that sufficient funding
will be obtained. See "SOURCES AND AMOUNT OF FUNDS."

RISK FACTORS
 
  Alliance's stockholders should consider carefully the information set forth
under the caption "Risk Factors," and all other information set forth in this
Proxy Statement/Prospectus, in evaluating whether to retain shares of Alliance
Common Stock and/or vote in favor of the Recapitalization Merger Agreement and
the Recapitalization.
 
RECENT DEVELOPMENTS
 
  On October 20, 1997, Alliance announced the execution of a definitive
agreement to acquire Medical Consultants Imaging Co. ("MCIC"), a Cleveland,
Ohio based provider of mobile MRI services, CT services and other outsourced
healthcare services. The acquisition also includes MCIC's one-half interest in
an operating joint venture in Michigan. The purchase price consists of $13
million in cash (subject to certain reductions) plus the assumption of
approximately $5 million in financing arrangements. MCIC operates 14 mobile MRI
systems and several other diagnostic imaging systems, primarily in Ohio,
Michigan, Indiana and Pennsylvania. The transaction was completed on November
21, 1997. In addition, Alliance is currently engaged in acquisition discussions

SUMMARY HISTORICAL FINANCIAL INFORMATION
 
  The summary historical consolidated financial information of Alliance with
respect to each year in the three-year period ended December 31, 1996, is
derived from the consolidated financial statements of Alliance, which have been
audited by Ernst & Young LLP, independent auditors. The financial information
for the three and nine months ended September 30, 1996 and 1997 are unaudited,
but in the opinion of management, reflects all adjustments necessary for a fair
presentation of such information. Operating results for the three and nine
months ended September 30, 1997, are not necessarily indicative of the results
that may be expected for the fiscal year ending December 31, 1997. The summary
historical consolidated financial information provided below should be read in
conjunction with the consolidated financial statements and notes thereto
included elsewhere in this Proxy Statement/Prospectus. See "INDEX TO
CONSOLIDATED FINANCIAL STATEMENTS."

(1) Net income (loss) includes special charges of $13.3 million for the year
    ended December 31, 1994 related to an equipment exchange transaction, the
    impairment of certain equipment, debt restructuring and employee
    severances; extraordinary gains (net of tax) of $6.3 million for the year
    ended December 31, 1996 related to the early extinguishment of debt; and an
    extraordinary gain (net of tax) of $1.3 million for the nine months ended
    September 30, 1997 related to the early extinguishment of debt.
(2) As adjusted consolidated balance sheet data at September 30, 1997 reflects
    the historical consolidated balance sheet of Alliance adjusted to give
    effect to the Transactions as if they had occurred at September 30, 1997.
    Pro forma interest expense, net, reflects net cash interest expense as
    adjusted to give effect to the Transactions as if they had occurred as of
    January 1, 1996 for the year ended December 31, 1996, and as of January 1,
    1997 for the three and nine month periods ended September 30, 1997. See
    "UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION."
(3) EBITDA is defined herein as income before income taxes, plus depreciation,
    amortization, net interest expense and other non-recurring items
    (principally noncash). EBITDA is presented because the Company believes it
    is a widely accepted financial indicator of a company's ability to service
    and/or incur indebtedness. However, EBITDA should not be considered as an
    alternative to net income as a measure of operating results or to cash
    flows as a measure of liquidity in accordance with generally accepted
    accounting principles.
(4) EBITDA margin is defined herein as EBITDA divided by revenues. The Company
    believes EBITDA margin provides a comparative reference to measure EBITDA
    performance from period to period and against comparable sized companies in
    the industry and, as such, provides a supplemental mechanism to evaluate
    efficiency and overall operating performance.
(5) The substantial majority of Alliance's historical capital expenditures have
    related to either major upgrades to existing systems or the replacement of
    older, less-advanced systems with new, state-of-the-art technologically
    advanced systems. As a result of these historical investments, the Company
    believes that it has upgraded substantially all of its systems and expects
    most of its capital expenditures for at least the next three to five years
    to relate to net fleet additions through new system purchases.
(6) Represents period over period revenue growth for customers that generated
    revenues for the entire term of both periods.
(7) For purposes of computing this ratio, earnings consist of income before
    income taxes plus fixed charges. Fixed charges consist of interest expense
    and one-third of the rent expense from long-term equipment operating
    leases, which management believes is a reasonable approximation of an
    interest factor. Alliance's earnings were insufficient to cover fixed
    charges by $18.0 million for the year ended December 31, 1994.

<PAGE>
 
                                 RISK FACTORS
 
  Alliance's stockholders should consider carefully the factors set forth
below as well as the other information set forth in this Proxy
Statement/Prospectus in evaluating whether to retain shares of Alliance Common
Stock and/or vote in favor of the Recapitalization Merger Agreement and the
Recapitalization.
 
CONTROL BY APOLLO; POTENTIAL FOR CONFLICTS OF INTEREST
 
  Upon consummation of the Recapitalization, Apollo will own approximately 84%
of the outstanding shares of Alliance Common Stock (approximately 74% on a
fully diluted basis). Accordingly, Apollo and its general partner will control
the Company, have the ability to obtain a change-in-control premium on the
sale of its shares (which premium may not be available to Alliance's public
stockholders) and have the power to elect all of its directors, appoint new
management and approve any action requiring the approval of the holders of
shares of Alliance Common Stock, including adopting amendments to Alliance's
certificate of incorporation and approving mergers or sales of substantially
all of Alliance's assets. Apollo also holds a controlling interest in SMT
Health Services Inc. ("SMT"), a leading provider of mobile MRI services in the
Mid-Atlantic region of the United States and a competitor of the Company. If
acquisition or other opportunities in the MRI industry are presented to
Apollo, no assurance can be given that Apollo will offer such opportunities to
Alliance and not to SMT.
 
POSSIBLE DELISTING; LOSS OF LIQUIDITY
 
  Following the consummation of the Recapitalization and depending on the
number of holders of shares of Alliance Common Stock remaining, Alliance
anticipates that it may be necessary and/or desirable to have Alliance's
Common Stock, which is currently traded on The Nasdaq SmallCap Market,
delisted. Any delisting of Alliance Common Stock, together with the
substantial decrease in the number of shares of Alliance Common Stock to be
held by holders thereof other than the Investor, is expected to result in a
substantial decrease in the liquidity of Alliance Common Stock, even if the
Company continues to be a reporting company under the Exchange Act and
continues to file the periodic reports (including annual and quarterly
reports) required to be filed thereunder. Upon any such delisting, shares of
Alliance Common Stock would trade only in the over-the-counter market.
Although prices in respect of trades would be published periodically by the
National Association of Securities Dealers, Inc. in the "pink sheets," quotes
for such shares may not be readily available. As a result, it is anticipated
that such shares would have a lower trading volume than the trading volume of
such shares prior to the Recapitalization.
 
TERMINATION OF SEC REPORTING
 
  If, as a result of the Recapitalization, shares of Alliance Common Stock are
held by fewer than 300 stockholders of record the Company will deregister the
Alliance Common Stock under the Exchange Act. If the Alliance Common Stock is
so deregistered, the Company will not be required to comply with the proxy or
periodic reporting requirements of the Exchange Act and does not plan to
provide any reports or information to public stockholders other than pursuant
to the right of such stockholders to inspect the books and records of the
Company as required by the DGCL. As a result, the information available to
stockholders on the business and financial condition of the Company would be
reduced, which could have a material adverse effect on the value of the
Alliance Common Stock. The Company currently plans to file with the Commission
and distribute to holders of the Notes copies of the financial information
that would have been contained in annual reports and quarterly reports,
including management's discussion and analysis of financial condition and
results of operations, that the Company would have been required to file with
the Commission pursuant to the Exchange Act. However, the Company will remain
subject to such reporting obligations only until the Notes are repaid or, by
their terms, no longer require the Company to be subject to such reporting
obligations.
 
SUBSTANTIAL LEVERAGE
 
  After giving effect to the Recapitalization, the Company's consolidated
indebtedness will be approximately $221.9 million. This high level of
indebtedness in comparison to historical indebtedness may reduce the
 
                                      20
<PAGE>
 
flexibility of the Company to respond to changing business and economic
conditions, as well as limit capital expenditures of the Company. The Credit
Agreement and the Indenture (as defined in "SOURCES AND AMOUNT OF FUNDS--
Notes") will include significant operating and financial restrictions, such as
limits on the Company's ability to incur indebtedness. On a pro forma basis
after giving effect to the Transactions, the Company's earnings would have
been insufficient to cover fixed charges by $8.3 million for the year ended
December 31, 1996 and by $0.7 million for the nine months ended September 30,
1997.
 
  The Company's high degree of leverage may have important consequences for
the Company, including: (i) the ability of the Company to obtain additional
financing for acquisitions, working capital, capital expenditures or other
purposes, if necessary, may be impaired or such financing may not be on terms
favorable to the Company; (ii) a substantial portion of the Company's cash
flow will be used to pay the Company's interest expense, which will reduce the
funds that would otherwise be available to the Company for its operations and
future business opportunities; (iii) a substantial decrease in net operating
cash flows or an increase in expenses of the Company could make it difficult
for the Company to meet its debt service requirements and force it to modify
its operations; (iv) the Company may be more highly leveraged than its
competitors which may place it at a competitive disadvantage; and (v) the
Company's high degree of leverage may make it more vulnerable to a downturn in
its business or the economy generally. Any inability of the Company to service
its indebtedness or obtain additional financing, as needed, would have a
material adverse effect on the Company. A significant portion of the
indebtedness to be incurred by the Company to finance the Recapitalization
will bear interest at variable rates. Any increase in the interest rates on
the Company's indebtedness will reduce funds available to the Company for its
operations and future business opportunities and will exacerbate the
consequences of the Company's leveraged capital structure. It is also expected
that the Company will have a substantial stockholders' deficit (approximately
$88.9 million on a pro forma basis at September 30, 1997) as a result of the
Recapitalization because the cash paid to stockholders, as well as all of the
expenses of the Recapitalization, will be charged to stockholders' equity. In
addition, the substantial leverage will have a negative effect on the
Company's net income.
 
RESTRICTIVE DEBT COVENANTS
 
  The Credit Agreement is expected to contain a number of significant
covenants that, among other things, will restrict the ability of the Company
to (i) declare dividends or redeem or repurchase capital stock, (ii) prepay,
redeem or purchase debt, including the Notes, (iii) incur liens and engage in
sale-leaseback transactions, (iv) make loans and investments, (v) incur
additional indebtedness, (vi) amend or otherwise alter debt and other material
agreements, (vii) make capital expenditures, (viii) engage in mergers,
acquisitions and asset sales, (ix) enter into transactions with affiliates and
(x) alter the business it conducts. The indebtedness outstanding under the
Credit Agreement will be guaranteed by substantially all of the Company's
domestic subsidiaries and will be secured by a first priority lien on
substantially all of the properties and assets of the Company and its
subsidiaries, now owned or acquired later, including a pledge of all of the
shares of the Company's existing and future subsidiaries and up to 65% of the
shares of the Company's future foreign subsidiaries which are owned by the
Company or one of its subsidiaries. In addition, under the Credit Agreement,
the Company will also be required to comply with financial covenants with
respect to (i) a maximum leverage ratio; (ii) minimum consolidated EBITDA;
(iii) a minimum interest coverage ratio; and (iv) a minimum fixed charge
coverage ratio. If the Company were unable to borrow under the Credit
Agreement due to a default, it would be left without sufficient liquidity. See
"SOURCES AND AMOUNT OF FUNDS--Credit Agreement."
 
  In addition, the indenture pursuant to which the Notes will be issued (the
"Indenture") will contain certain covenants that, among other things, limit
the ability of the Company and its Restricted Subsidiaries (as defined in the
Indenture) to (i) incur additional indebtedness, (ii) incur liens, (iii) pay
dividends or make certain other restricted payments, (iv) consummate certain
asset sales, (v) enter into certain transactions with affiliates, (vi) merge
or consolidate with any other person or sell, assign, transfer, lease, convey
or otherwise dispose of all or substantially all of the assets of the Company
and (vii) impose restrictions on the ability of certain subsidiaries to pay
certain dividends or make certain payments to the Company. See "SOURCES AND
AMOUNT OF FUNDS--Notes."

ISSUANCE OF SERIES F PREFERRED STOCK
   
  The Company will issue $15.0 million stated amount of Series F Preferred
Stock to Apollo and the BT Investor in connection with the Recapitalization.
The Series F Preferred Stock pays quarterly dividends at the rate of 13.5% per
annum, payable in kind for the first five years from the date of issuance, and
thereafter only in cash. The Series F Preferred Stock ranks senior to the
Alliance Common Stock and its liquidation preference entitles the holders,
upon any liquidation or sale of the Company (including a sale of assets, sale
of stock, merger or otherwise), to a distribution of the Company's assets
prior to any payment to any other equity holders of the Company, including the
holders of the shares of Alliance Common Stock to be retained in connection
with the Recapitalization. Furthermore, the Series F Preferred Stock is
required to be redeemed by the Company ten years after the issue date for its
aggregate accreted face value. The dividend and redemption provisions of the
Series F Preferred Stock will reduce the Company's cash available for
distributions to the holders of Alliance Common Stock.     
 
REGULATION
 
  Many aspects of the medical industry in the United States, including the
Company's business, are subject to extensive federal and state government
regulation. Although the Company believes that its operations comply with
applicable regulations, there can be no assurance that subsequent adoption of
laws or interpretations of existing laws will not regulate, restrict or
otherwise adversely affect the Company's business.
 
  The marketing and operation of the Company's MRI and computed axial
tomography ("CT") systems are subject to state laws prohibiting the practice
of medicine by non-physicians. Management believes that its operations do not
involve the practice of medicine because all professional medical services
relating to its operations, such as the interpretation of the scans and
related diagnoses, are separately provided by licensed physicians not employed
by the Company. Further, the Company believes that its operations do not
violate state laws with respect to the rebate or division of fees.
 
  The Company is subject to federal and state laws which govern financial and
other arrangements between health care providers. These include the federal
Medicare and Medicaid anti-kickback statutes which prohibit bribes, kickbacks,
rebates and any other direct or indirect remuneration in return for or to
induce the referral of an individual to a person for the furnishing, directing
or arranging of services, items or equipment for which payment may be made in
whole or in part under Medicare, Medicaid or other federal health care
programs. Violation of the anti-kickback statute may result in criminal
penalties and exclusion from the Medicare and other federal health care
programs. Many states have enacted similar statutes which are not necessarily
limited to items and services paid for under Medicare or a federally funded
health care program. In recent years, there has been increasing scrutiny by
law enforcement authorities, the U.S. Department of Health and Human Services
("HHS"), the courts and Congress of financial arrangements between health care
providers and potential sources of patient and similar referrals of business
to ensure that such arrangements are not designed as mechanisms to pay for
patient referrals. HHS interprets the anti-kickback statute broadly to apply
to distributions of partnership and corporate profits to investors who refer
federal health care program patients to a corporation or partnership in which
they have an ownership interest and to payments for service contracts and
equipment leases that are designed to provide direct or indirect remuneration
for patient referrals or similar opportunities to furnish reimbursable items
or services. In July 1991, HHS issued "safe harbor" regulations that set forth
certain provisions which, if met, will assure that health care providers and
other parties who refer patients or other business opportunities, or who
provide reimbursable items or services, will be deemed not to violate the
anti-kickback statute. The Company is also subject to separate laws governing
the submission of false claims. The Company is a party to a partnership for
provision of MRI services. The Company believes that the partnership is in
compliance with the anti-kickback statute. The Company believes that its other
operations likewise comply with the anti-kickback statutes.
 
  A federal law, commonly known as the "Stark Law," also imposes civil
penalties and exclusions for referrals for "designated health services" by
physicians to certain entities with which they have a financial
 
                                      22
<PAGE>
 
relationship (subject to certain exceptions). "Designated health services"
include, among other things, MRI services. While implementing regulations have
been issued relating to referrals for clinical laboratory services, no
implementing regulations have been issued regarding the other designated
health services, including MRI services. In addition, several states in which
the Company operates have enacted or are considering legislation that
prohibits "physician self-referral" arrangements or requires physicians to
disclose any financial interest they may have with a health care provider to
their patients to whom they recommend that provider. Possible sanctions for
violating these provisions include loss of licensure and civil and criminal
sanctions. Such state laws vary from state to state and seldom have been
interpreted by the courts or regulatory agencies. Nonetheless, strict
enforcement of these requirements is likely. The Company believes its
operations comply with these federal and state physician self-referral laws.
 
  In some states, a certificate of need ("CON") or similar regulatory approval
is required prior to the acquisition of high-cost capital items including
diagnostic imaging systems or provision of diagnostic imaging services by the
Company or its customers. CON regulations may limit or preclude the Company
from providing diagnostic imaging services or systems. A significant increase
in the number of states regulating the Company's business within the CON or
state licensure framework could adversely affect the Company. Conversely,
repeal of existing CON regulations in jurisdictions where the Company has
obtained or operates under a CON could also adversely affect the Company. This
is an area of continuing legislative activity, and there can be no assurance
that the Company will not be subject to CON and licensing statutes in other
states in which it operates or may operate in the future. See "BUSINESS--
Regulation."
 
REIMBURSEMENT OF HEALTH CARE COSTS; COST CONTAINMENT PRESSURES; CONTRACTS
 
  The majority of payments to the Company are received directly from health
care providers, rather than from private insurers, other third party payors or
governmental entities. To a lesser extent, the Company's revenues are
generated from direct billings to patients or their medical payors which are
recorded net of contractual discounts and other arrangements for providing
services at discounted prices. Under current reimbursement regulations, the
Company is prohibited from billing the insurer or the patient directly for
services provided for hospital inpatients or outpatients. Payment to health
care providers by third party payors for the Company's diagnostic services
depends substantially upon such payors' reimbursement policies. Consequently,
those policies have a direct effect on health care providers' ability to pay
for the Company's services and an indirect effect on the Company's level of
charges. Ongoing concerns about rising health care costs may cause more
restrictive reimbursement policies to be implemented in the future.
Restrictions on reimbursements to health care providers may affect such
providers' ability to pay for the services offered by the Company and could
indirectly adversely affect the Company's financial performance. See
"BUSINESS--Reimbursement" and "BUSINESS--Regulation."
 
  The current health care environment is characterized by cost containment
pressures which the Company believes have resulted in decreasing revenues per
scan. Although scan prices appear to have stabilized, the Company expects
modest continuing downward pressure on pricing levels. Although the Company
has experienced increased scan volumes in 1995, 1996 and 1997, it has also had
periods of declining volumes in prior years, and there can be no assurance
that the recent positive trends will continue. Among other things, the Company
is subject to the risk that customers will cease using the Company's MRI
services upon expiration of contracts and purchase or lease their own MRI
systems. In the past, when this has occurred, the Company has generally been
able to obtain replacement customers. However, it is not always possible to
immediately obtain replacement customers, and some replacement customers have
been smaller facilities and have had lower scan volumes.
 
ACQUISITION STRATEGY
 
  The Company's expansion and acquisition strategy may require substantial
capital, and no assurance can be given that the Company will be able to raise
any necessary additional funds through bank financing or the issuance of
equity or debt securities. Sufficient funds may not be available on terms
acceptable to the Company, if at all. There can be no assurance that the
Company will be able to successfully integrate the operations of any future
acquisitions.
 
                                      23
<PAGE>
 
TECHNOLOGICAL CHANGE AND OBSOLESCENCE
 
  The Company's services require the use of state-of-the-art medical equipment
that has been characterized by rapid technological advances. Although the
Company believes that substantially all the MRI and CT systems it provides can
be upgraded to maintain their state-of-the-art character, the development of
new technologies or refinements of existing ones might make the Company's
existing systems technologically or economically obsolete, or cause a
reduction in the value of, or reduce the need for, the Company's systems. MRI
systems are currently manufactured by numerous companies. Competition among
manufacturers for a greater share of the MRI systems market may result in
technological advances in the capacity of these new systems. Consequently, the
obsolescence of the Company's systems may be accelerated. Although the Company
is aware of no substantial technological change, should such change occur,
there can be no assurance that the Company will be able to acquire the new or
improved systems which may be required to service its customers.
 
FRAUDULENT TRANSFER CONSIDERATIONS
 
  The payment of the consideration in the Recapitalization to the stockholders
of Alliance and the related financing (including the issuance of the Notes and
the incurrence of the guarantees thereunder) may be subject to review under
federal or state fraudulent transfer laws. While the relevant laws may vary
from state to state, under such laws, if a court in a lawsuit by a creditor or
a representative of creditors of Alliance, such as a trustee in bankruptcy or
one of such entities as debtor-in-possession, were to find that, at the time
of or after and giving effect to the Transactions, Alliance (i) was insolvent
or rendered insolvent thereby, (ii) was engaged in a business or transaction
for which its remaining assets constituted unreasonably small capital, (iii)
intended to incur, or believed that it would incur, debts beyond its ability
to pay as they matured, or (iv) intended to hinder, delay or defraud creditors
and, in the case of clauses (i), (ii) and (iii), that Alliance did not receive
reasonably equivalent value or fair consideration in the Recapitalization,
such court could avoid all or a part of the payment of the consideration in
the Recapitalization and require that the stockholders, including stockholders
exercising appraisal rights, return such consideration to Alliance or to a
fund for the benefit of their respective creditors. In addition, if a court
were to find that Alliance came within any of clauses (i) through (iv) above,
Alliance, or its respective creditors or trustees in bankruptcy, could seek to
avoid the grant of security interests to the lenders under the Credit
Agreement or to subordinate or void altogether the Notes and the guarantees
thereunder. This would result in an event of default with respect to such
indebtedness which, under the terms of such indebtedness (subject to
applicable law), would allow the lenders to terminate their obligations
thereunder and to accelerate payment of such indebtedness.
 
  The measure of insolvency for purposes of the foregoing will vary depending
upon the law of the jurisdiction which is being applied. There can be no
certainty as to what law a court would apply pursuant to applicable choice of
law provisions, although it is likely that a court would apply the law of the
state of incorporation of Alliance, federal bankruptcy law, the law of the
jurisdiction in which the headquarters of Alliance is located or the law of
the jurisdiction in which the Recapitalization is deemed to have occurred.
Generally, however, a company would be considered insolvent for purposes of
the foregoing if the sum of such company's debts is greater than all such
company's property at a fair valuation, or if the present fair saleable value
of such company's assets is less than the amount that will be required to pay
its probable liability on its existing debts as they become absolute and
matured. There can be no assurance, however, that a court would not determine
that Alliance was insolvent at the time of or after and giving effect to the
Recapitalization. In addition, there can be no assurance that a court would
not determine, regardless of whether Alliance was solvent, that the
Recapitalization constituted a fraudulent transfer on another of the grounds
listed above. Management believes that Alliance will be solvent following the
consummation of the Transactions.
 
RELIANCE ON KEY PERSONNEL
 
  The Company's success depends in large part upon a number of key management
personnel, principally Messrs. Zehner and Pino. The loss of the service of one
or more of its executive officers or other key management personnel could have
a material adverse effect on the Company. Messrs. Zehner and Pino have entered
into the Employment Agreements with Alliance and an agreement not to compete
with Alliance which will become effective at the Recapitalization Effective
Time. See "MANAGEMENT."
 
                                      24
<PAGE>
 
COMPETITION
 
  The market for diagnostic imaging services and imaging systems is highly
competitive. In addition to direct competition from other mobile providers,
the Company competes with free-standing imaging centers and health care
providers that have their own diagnostic imaging systems and with equipment
manufacturers that sell or lease imaging systems to health care providers for
full-time installation. Some of the Company's direct competitors that provide
contract MRI services may have access to greater financial resources than the
Company. In addition, some of the Company's customers are capable of providing
the same services to their patients directly, subject only to their decision
to acquire a high-cost diagnostic imaging system, assume the associated
financial risk, employ the necessary technologists and satisfy applicable
licensure and CON requirements, if any.
 
FEDERAL INCOME TAX TREATMENT
 
  A stockholder that actually retains less than all of such stockholder's
Alliance Common Stock may, under certain circumstances, be required to treat
the receipt of a portion of any cash received in the Recapitalization as the
receipt of a dividend (rather than as the receipt of proceeds from the sale of
the Alliance Common Stock, which would generally receive capital gains
treatment). No such dividend treatment should be applicable to stockholders
who do not actually retain and are not deemed for tax purposes to retain any
shares of Alliance Common Stock and receive cash for all of their shares in
the Recapitalization. See "THE RECAPITALIZATION--Certain Tax Consequences of
the Recapitalization."

CREDIT AGREEMENT
 
  General. Pursuant to a commitment letter dated as of November 10, 1997 from
Bankers Trust Company (the "Agent") to Apollo (the "Commitment Letter") and
subject to the negotiation, execution and delivery of definitive
documentation, the Agent has committed to lend to the Company (the "Loans"),
$50 million in the form of the Term Loan Facility and up to $75 million in the
form of the Revolving Loan Facility for an aggregate principal amount of up to
$125 million (the "Commitment").
 
  Pursuant to the Commitment Letter, the Agent reserves the right to syndicate
all or a portion of the Commitment to one or more financial institutions
(including the Agent, each, a "Lender"), such institutions being subject to
the Company's approval. Upon the acceptance of the commitment of any Lender to
provide a portion of the Commitment, the Agent will be released from that
portion of the Commitment. In addition, the Agent agrees to serve as
administrative and syndication agent in connection with the Loans, as well as
fronting bank in connection with the letters of credit issued under the
Revolving Loan Facility.
 
                                      27
<PAGE>
 
  The following terms and descriptions of the Loans are based upon the terms
set forth in the Commitment Letter and are subject to the final negotiation
and execution of the Credit Agreement and related documents. As a result, the
final terms of the Loans may vary from those set forth below.
 
  Use of Proceeds; Maturity. The Loans are expected to be made available to
the Company to finance in part the Recapitalization and certain related costs
and expenses, and to refinance certain existing indebtedness of Alliance. The
full amount to be borrowed under the Term Loan Facility must be drawn in a
single drawing on the date the Term Loan Facility is closed, which is expected
to be the date on which the Transactions close (the "Closing Date"). The
Revolving Loan Facility is expected to be available at the Closing Date and
thereafter to finance (including through the making of revolving loans and the
issuance of letters of credit) working capital requirements and general
corporate purposes of the Company. The Term Loan Facility matures on the sixth
anniversary of the Closing Date. The Revolving Loan Facility will mature on
the fifth anniversary of the Closing Date. The Credit Agreement will require
the Company to reduce the commitments under the Revolving Loan Facility to
$37.5 million on the fourth anniversary of the Closing Date and to make annual
amortization payments of $0.5 million per year in the first five years and
$47.5 million in the sixth year.
 
  Prepayments. Loans are required to be prepaid with (a) 100% of the net
proceeds of all non-ordinary-course asset sales or other dispositions of the
property by the Company and its subsidiaries, subject to limited exceptions,
(b) 100% of the net proceeds of issuances of debt obligations and certain
preferred stock by the Company and its subsidiaries, subject to limited
exceptions, (c) 50% of the net proceeds from common equity and certain
preferred stock issuances by the Company and its subsidiaries, subject to
limited exceptions, (d) 75% of annual excess cash flow and (e) 100% of certain
insurance proceeds, subject to limited exceptions. Such mandatory prepayments
will be allocated as follows: first, to the Term Loan Facility and second, to
the Revolving Loan Facility.
 
  Voluntary prepayments will be permitted in whole or in part, at the option
of the Company, in minimum principal amounts to be agreed upon, without
premium or penalty, subject to reimbursement of the Lender's re-deployment
costs in the case of prepayment of Reserve Adjusted Eurodollar Loans (as
defined in the Commitment Letter) other than on the last day of the relevant
interest period.
 
  Interest and Fees. The interest rates under the Loans will be as follows:
 
  (a) Term Loan Facility: At the option of the Company, (i) 1.50% in excess of
the higher of (A) 1/2 of 1% in excess of the Federal Reserve reported
certificate of deposit rate and (B) the rate that the Agent announces from
time to time as its prime lending rate, as in effect from time to time, and
(ii) 2.50% in excess of the Reserve Adjusted Eurodollar Rate, in each case,
subject to decreases based upon the Company's leverage ratio.
 
  (b) Revolving Loan Facility: At the option of the Company, (i) 1.25% in
excess of the higher of (A) 1/2 of 1% in excess of the Federal Reserve
reported certificate of deposit rate and (B) the rate that the Agent announces
from time to time as its prime lending rate, as in effect from time to time,
and (ii) 2.25% in excess of the Reserve Adjusted Eurodollar Rate, in each
case, subject to decreases based upon the Company's leverage ratio.
 
  The Company may elect interest periods of 1, 2, 3 or 6 months for Reserve
Adjusted Eurodollar Loans. With respect to Reserve Adjusted Eurodollar Loans,
interest will be payable at the end of each interest period and, in any event,
at least every 3 months. With respect to Base Rate Loans (as defined in the
Commitment Letter), interest will be payable quarterly on the last business
day of each fiscal quarter. In each case, calculation of interest will be on
the basis of actual number of days elapsed in a year of 360 days.
 
  The Commitment Letter provides for payment by the Company in respect of
outstanding letters of credit of (i) a per annum fee equal to the spread over
the Reserve Adjusted Eurodollar Rate for the Revolving Loan Facility from time
to time in effect, (ii) a fronting fee equal to 1/4 of 1% on the aggregate
outstanding stated
 
                                      28
<PAGE>
 
amounts of such letters of credit, plus (iii) customary administrative
charges. The Company will also pay a commitment fee equal to 1/2 of 1% per
annum on the undrawn portion of the available Commitment, subject to decreases
based on the Company's leverage ratio.
 
  Collateral and Guarantees. The Loans will be guaranteed by all of the
Company's existing and future direct and indirect wholly owned domestic
subsidiaries. The Loans will be secured by a first priority lien in
substantially all of the properties and assets of the Company and its direct
and indirect wholly owned domestic subsidiaries, now owned or acquired later,
including a pledge of all capital stock and notes owned by the Company and its
subsidiaries; provided that, in certain cases, no more than 65% of the stock
of foreign subsidiaries of the Company shall be required to be pledged.
 
  Representations and Warranties and Covenants. The Commitment Letter provides
that the Credit Agreement documentation will contain certain customary
representations and warranties by the Company. In addition, the Credit
Agreement is expected to contain customary covenants restricting the ability
of the Company to, among others (i) declare dividends or redeem or repurchase
capital stock; (ii) prepay, redeem or purchase debt; (iii) incur liens and
engage in sale-leaseback transactions; (iv) make loans and investments; (v)
incur additional indebtedness; (vi) amend or otherwise alter debt and other
material agreements; (vii) make capital expenditures; (viii) engage in
mergers, acquisitions and asset sales; (ix) transact with affiliates; and (x)
alter the business it conducts. It is also expected that the Company will be
required to indemnify the Agent and comply with specified financial covenants
and make certain customary affirmative covenants.
 
  Events of Default. Events of default under the Credit Agreement are expected
to include (i) the Company's failure to pay principal or interest when due;
(ii) the Company's material breach of any representation or warranty contained
in the loan documents; (iii) covenant defaults; (iv) events of bankruptcy; and
(v) a change of control of the Company.

                              THE SPECIAL MEETING
 
TIME AND PLACE
 
  The Special Meeting of Alliance's stockholders will be held at the offices
of Alliance, 1065 North PacifiCenter Drive, Suite 200, Anaheim, California
92806, on the Special Meeting Date.
 
RECORD DATE; STOCK ENTITLED TO VOTE; QUORUM
 
  Only record holders of Alliance Common Stock at the close of business on the
Record Date will be entitled to receive notice of and to vote at the Special
Meeting. At the close of business on the Record Date, Alliance had 11,023,344
shares of Alliance Common Stock outstanding and entitled to vote. The
presence, in person or by proxy, at the Special Meeting of the holders of at
least a majority of the votes entitled to be cast at the Special Meeting is
necessary to constitute a quorum for the transaction of business. Shares of
Alliance Common Stock represented by Proxies which are marked "abstain" or
which are not marked as to any particular matter or matters will be counted as
shares present for purposes of determining the presence of a quorum on all
matters but will not be counted as votes cast in favor of the Recapitalization
Merger Agreement. Proxies relating to "street name" shares that are voted by
brokers will be counted as shares present for purposes of determining the
presence of a quorum on all matters, but will not be treated as shares having
voted at the Special Meeting as to any proposal as to which authority to vote
is withheld by the broker.
 
MATTERS TO BE CONSIDERED
 
  The purpose of the Special Meeting is to vote on the Recapitalization Merger
Agreement. The Recapitalization Merger Agreement provides for, among other
things, (1) the Recapitalization, (2) the Investor to purchase 150,000 shares
of Series F Preferred Stock, (3) the resignation of members of Alliance's
current Board of Directors and the election of persons designated by the
Investor to Alliance's Board of Directors and (4) the amendment and
restatement of Alliance's Restated Certificate of Incorporation.
 
  If the Recapitalization Merger Agreement is approved by holders of a
majority of the shares of Alliance Common Stock, then at the Recapitalization
Effective Time, the separate corporate existence of Newco will cease, the
Company will continue as the surviving corporation, the shares of common stock
of Newco will be converted into 3,632,222 shares of Alliance Common Stock,
411,358 shares of Alliance Common Stock will be retained by Alliance's
existing stockholders and the balance of the outstanding shares of Alliance
Common Stock (other than Dissenting Shares) will be converted into the right
to receive $11.00 per share in cash.
 
  The Recapitalization Merger Agreement provides that an aggregate of 411,358
shares of Alliance Common Stock will be retained by Alliance's existing
stockholders. Each stockholder of Alliance may elect to retain shares of
Alliance Common Stock by following the procedures set forth in "THE
RECAPITALIZATION--Proration." If Alliance's stockholders elect to retain more
or less than 411,358 shares of Alliance Common Stock, the number of shares to
be retained will be prorated as described in "THE RECAPITALIZATION--
Proration." Consequently, at the time holders of shares of Alliance Common
Stock vote in respect of the Recapitalization Merger Agreement and decide
whether to elect to retain shares of Alliance Common Stock, they will not know
if they will be entitled to retain all of the shares they elect to retain or
if they will be required to retain shares of Alliance Common Stock which they
do not elect to retain. The Principal Stockholders will be entitled to
participate in the proration of the retained shares in the same manner as
Alliance's other stockholders, unless the Investor exercises the option (in
which case, the Principal Stockholders would receive cash for their shares and
would not be subject to proration). The Investor has advised the Company that
it does not currently intend to exercise the option and would do so only if a
third party sought to acquire Alliance prior to consummation of the
Recapitalization or the termination of the Recapitalization Merger Agreement.
If the Investor does exercise the options, all 411,358 of the retained shares
would be prorated among Alliance's existing public stockholders, who own
approximately 34% of the issued and outstanding shares of Alliance Common
Stock (assuming the conversion or exercise by the Principal Stockholders of
all of their securities which are convertible into or exercisable for shares
of Alliance Common Stock). See "THE RECAPITALIZATION--Proration."

  Pursuant to the Recapitalization Merger Agreement, Apollo will receive a
total of 3,632,222 shares of Alliance Common Stock. Consequently, immediately
after the Recapitalization, Alliance will have 4,043,580 common shares
outstanding, of which Apollo will own 3,632,222 shares (or approximately 90%)
and Alliance's existing stockholders will own 411,358 shares (or approximately
10%). Immediately after consummation of the Recapitalization, Apollo intends
to sell 242,898 shares of Alliance Common Stock owned by Apollo to BT for
$11.00 per share (or approximately $2.7 million in the aggregate) in cash, the
amount paid to Alliance's existing stockholders for their shares of Alliance
Common Stock. Immediately after consummation of the Transactions, Apollo also
intends to sell to BT 9,000 shares ($0.9 million stated amount) of the Series
F Preferred Stock purchased by it for $0.9 million in cash. In addition,
options to acquire 524,545 shares of Alliance Common Stock will be held by or
subject to issuance to management of Alliance after consummation of the
Recapitalization. See "THE RECAPITALIZATION--Interests of Certain Persons in
the Recapitalization," "CERTAIN RELATED AGREEMENTS--The New Option Plan."
 
  THE BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE RECAPITALIZATION MERGER
AGREEMENT AND HAS DETERMINED, AMONG OTHER THINGS, THAT THE RECAPITALIZATION
MERGER AGREEMENT IS FAIR TO AND IN THE BEST INTERESTS OF ALLIANCE'S
STOCKHOLDERS, AND RECOMMENDS THAT ALLIANCE'S STOCKHOLDERS APPROVE THE
RECAPITALIZATION MERGER AGREEMENT.
 
  THE RECOMMENDATION BY THE BOARD OF DIRECTORS THAT ALLIANCE'S STOCKHOLDERS
APPROVE THE RECAPITALIZATION MERGER AGREEMENT IS NOT A RECOMMENDATION AS TO
WHETHER STOCKHOLDERS SHOULD RETAIN SHARES OF ALLIANCE COMMON STOCK.
 
REQUIRED VOTE
 
  The affirmative vote of the holders of a majority of the shares of Alliance
Common Stock entitled to vote thereon is required to approve the
Recapitalization Merger Agreement. However, pursuant to the Stockholder
Agreement, Apollo has the right to cause a majority of the outstanding shares
of Alliance Common Stock to be voted in favor of the Recapitalization Merger
Agreement and has an option to acquire all of such shares. Apollo intends to
cause the shares of Alliance Common Stock subject to the Stockholder Agreement
to be voted in favor of the approval of the Recapitalization Merger Agreement,
thereby ensuring the approval of the Recapitalization Merger Agreement without
the vote of any additional stockholders. See "CERTAIN RELATED AGREEMENTS--
Stockholder Agreement."
 
VOTING; REVOCATION OF PROXIES
 
  Shares of Alliance Common Stock represented by all properly executed Proxies
received in time for the Special Meeting (and not properly revoked) will be
voted in the manner specified in such Proxies. Proxies that do not contain any
instruction to vote for or against or to abstain from voting on a particular
matter will be voted in favor of such matter. It is not expected that any
matter other than those referred to herein will be brought before the
stockholders at the Special Meeting. If, however, other matters are properly
presented, the persons named as proxies will vote in accordance with their
best judgment with respect to such matters, unless authority to do so is
withheld in the Proxy. The persons appointed as proxies may not exercise their
discretionary voting authority to vote any such Proxy in favor of any
adjournments or postponements of the Special Meeting if instruction is given
to vote against the approval of the Recapitalization and any other proposals.
 
  Any Proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before the shares represented by such Proxy are voted at
the Special Meeting (1) by attending and voting in person at the Special
Meeting, (2) by giving notice of revocation of the Proxy at the Special
Meeting or (3) by delivering to the Secretary of Alliance (a) a written notice
of revocation or (b) a duly executed Proxy relating to the same shares and
matters to be considered at the Special Meeting, bearing a date later than the
Proxy previously executed. Attendance at the Special Meeting will not in and
of itself constitute a revocation of a Proxy. All written notices of
revocation and other communications with respect to revocation of proxies
should be addressed as follows: 1065 North PacifiCenter Drive, Suite 200,
Anaheim, California 92806, Attention: Secretary, and must be received before
the taking of the votes at the Special Meeting.

                             THE RECAPITALIZATION
 
BACKGROUND OF THE RECAPITALIZATION
 
  In late June 1996, senior management and consultants of U.S. Diagnostics
Labs, Inc. ("USDL") contacted senior management of Alliance to discuss a
possible business combination. During the first two weeks of August 1996,
management of the respective companies attempted to negotiate the terms of a
transaction involving the issuance of USDL stock in exchange for shares of
outstanding Alliance Common Stock. The Board of Directors and the management
of Alliance were attracted to a possible transaction with USDL based on a
number of factors, including the rapid growth of USDL and the resulting
superior liquidity in its stock and the possibility for synergies in the
combination of the two companies' businesses. Among other things, the Board of
Directors and management perceived that a combination with USDL would provide
enhanced access to capital and a superior medium to make acquisitions, in the
form of USDL's stock, in order to take advantage of consolidation
opportunities.
 
  Alliance engaged Salomon Brothers to assist it in connection with a possible
transaction with USDL pursuant to an engagement letter dated August 15, 1996.
On the same date, the Board of Directors of Alliance met to receive a report
by management on the terms of a proposed merger with USDL. On August 16, 1996,
based upon rumors in the marketplace concerning a possible sale of Alliance,
Alliance issued a press release indicating that it was in discussions for a
possible stock-for-stock merger with USDL in which shares of Alliance would be
valued at approximately $6.00-6.50 per share. The press release indicated that
the transaction was subject to a number of contingencies, including
satisfactory completion of due diligence by both companies and reaching
agreements with the holders of Alliance's senior notes, senior subordinated
debentures and Series A Preferred Stock with respect to the treatment of those
securities in the proposed transaction. Following additional due diligence and
negotiations and communications with the holders of those securities,
discussions between Alliance and USDL were terminated. On August 28, 1996,
Alliance issued a press release indicating that USDL informed Alliance that
the exchange ratio initially discussed by the parties could not be justified
by USDL and that USDL had been unsuccessful in reaching a mutually acceptable
agreement with the holders of certain of Alliance's senior notes, senior
subordinated debentures and Series A Preferred Stock.
 
  Following the termination of discussions with USDL, Alliance continued to
consider means of improving its operating flexibility in order to permit it to
take advantage of opportunities in the MRI marketplace. Management of Alliance
determined that certain restrictive provisions of Alliance's senior notes and
senior subordinated debentures were prejudicing Alliance's ability to take
advantage of these opportunities. As a result, beginning in the third quarter
of 1996 and continuing through the first quarter of 1997, Alliance arranged
the sale of its outstanding senior notes by the holders thereof to General
Electric Company and DVI Financial Services, Inc. and made substantial
modification to the terms of such senior notes. In addition, Alliance
negotiated with General Electric Company for new financing to enable Alliance
to retire its senior subordinated debentures and a series of preferred stock
previously outstanding. These financing transactions were concluded in March
1997. As a result, Alliance significantly improved its operating flexibility
by achieving the elimination or substantial easing of various restrictive
covenants.
 
  Beginning in the second quarter of 1997, Alliance, with the assistance of
Salomon Brothers, began to seek a strategic investment or relationship to
assist in taking advantage of consolidation opportunities in the MRI
marketplace. In addition, during the same period, Alliance engaged in
discussions with other MRI service providers regarding the potential
acquisition of such providers by Alliance. Such potential acquisitions were
identified by Alliance based on its knowledge of the MRI services industry.
 
  Salomon Brothers identified several different potential investors based upon
Salomon Brothers' knowledge of the investors interested in the health care
services industry and the investment criteria typically utilized by such
investors. On behalf of Alliance, Salomon Brothers contacted a number of these
potential investors and arranged for the execution of confidentiality
agreements with three strategic and financial investors, each of which
conducted due diligence with respect to Alliance. In May 1997, senior
management of Alliance met with representatives of a financial investor, which
indicated that it was prepared, subject to certain conditions, to make
 
                                      34
<PAGE>
 
a substantial minority investment in Alliance. Based upon discussions between
the financial investor and Salomon Brothers, Alliance believes that any
proposed transaction would have been for convertible debt or convertible
preferred stock having a per share value of $8.00 to $9.00 per share.
Discussions were not pursued with the financial investor because Alliance
management believed that the price discussed did not adequately reflect
Alliance's future growth prospects. On April 24, 1997, management of Alliance
met for the first time with representatives of Apollo and had subsequent
meetings with representatives of Apollo on April 30 and May 12. During this
period, Apollo conducted preliminary due diligence with respect to Alliance.
On June 3, 1997, Apollo's representatives preliminarily suggested the
possibility of a cash change of control transaction and provided to Alliance
management a worksheet which indicated a valuation of Alliance at
approximately $9.00 to $9.50 per share. The proposed Apollo transaction was
subject to a number of terms and conditions, including that management of
Alliance roll over approximately one-half of their personal holdings in
Alliance's stock. As a result, and based upon the proposed valuation, which
Alliance management believed did not adequately reflect Alliance's future
growth prospects, discussions were not continued at that time.
 
  On May 20, 1997, management of Alliance first met with senior management of
a publicly-traded healthcare company (the "Healthcare Company"). According to
publicly available information, as of July 31, 1997, the Healthcare Company
had total assets of approximately $323 million, and a market capitalization of
approximately $311 million. Representatives of the Healthcare Company also
suggested a change of control transaction, but proposed a stock-for-stock
merger rather than a cash transaction. On June 4, 1997, the Board of Directors
met to receive a report from management on the meetings conducted to date
regarding significant transactions. In view of such meetings and the
possibility that a transaction might be proposed that would result in a change
of control of Alliance, the Board established a committee of its members to
oversee discussions and, possibly, negotiations for a transaction involving
either a strategic investment in or change of control of Alliance (the
"Special Committee"). Douglas Hayes and Robert Waley-Cohen, both non-
management directors of Alliance, were appointed to constitute the Special
Committee.
 
  During the next week, management of Alliance continued discussions with
senior management of the Healthcare Company. As a result of substantial
progress in these discussions, a meeting of the Special Committee was convened
on June 11, 1997. Management indicated that the Healthcare Company transaction
was a stock-for-stock proposal at a fixed exchange ratio that would value
Alliance's Common Stock at approximately $11.00 per share, based upon the
current price of the Healthcare Company's stock. Accordingly, the value of the
stock-for-stock proposal would change with changes in the price of the
Healthcare Company's stock. Management explained to the members of the Special
Committee that the Healthcare Company requested a detailed letter of intent
but that, based upon the advice of Salomon Brothers and Alliance's outside
counsel, Irell & Manella LLP, Alliance had rejected that approach and instead
proposed moving directly to a definitive agreement, pending the completion of
due diligence by both parties and other prerequisites to signing. The
Healthcare Company thereupon requested an "exclusivity" agreement to ensure
that Alliance would not pursue discussions with other parties during a
relatively brief period of time to enable the parties to negotiate a
definitive agreement. The Special Committee authorized management to execute a
confidentiality agreement containing an exclusivity provision through June 27,
1997 to enable this process to continue.
 
  On June 14, 1997, Richard N. Zehner, Alliance's Chairman, Chief Executive
Officer and president, was contacted by telephone by Joshua Harris of Apollo.
Mr. Harris indicated that Apollo would be interested in pursuing discussions
concerning a possible transaction if Alliance sought to do so. Mr. Zehner
responded that he was precluded pursuant to an agreement with a third party
from discussing any possible transaction with Apollo. Mr. Harris indicated
that Apollo's initial indication of value was not final, and that Mr. Harris
believed that the valuation of Alliance's common shares could likely be
improved. On June 16, 1997, Mr. Harris distributed by facsimile a letter to
Mr. Zehner with a copy to the Board of Directors indicating that Apollo
remained interested in making a proposal for a significant transaction
involving Alliance.
 
  On June 16, 1997, the Board of Directors of Alliance met to receive a report
from management concerning progress in discussions with the Healthcare Company
and to consider the communications from Apollo. The Board of Directors was
informed, among other things, that the stock-for-stock transaction proposed by
the Healthcare Company was currently valued at approximately $11.00 per share
of Alliance Common Stock. The
 
                                      35
<PAGE>
 
Board of Directors considered the advantages and disadvantages of a stock-for-
stock transaction versus a possible cash transaction. A principal advantage of
a stock-for-stock transaction was that stockholders could continue to
participate in any appreciation of the combined companies following the
transaction. An important disadvantage of the stock-for-stock proposal was
that it would not provide liquidity to all stockholders. In addition, the
proposal was conditioned on achieving pooling-of-interests accounting
treatment and tax-free treatment, which would require the holders of a large
percentage of Alliance's stock to provide representations as to a lack of
current intention to sell shares. The Board of Directors was aware that
certain of the Principal Stockholders might not be willing to provide such a
representation and that as a result, there was a material risk that such a
stock-for-stock transaction might not be completed. The advantages of a cash
transaction included the fact that it would provide liquidity for stockholders
as well as the lack of a necessity that a large percentage of Alliance's
stockholders provide representations as to a lack of current intention to sell
shares. In view of Apollo's communications, the Board of Directors determined
that Alliance should not execute a definitive agreement with the Healthcare
Company until first having had an opportunity to obtain additional details
concerning Apollo's communications. The Board of Directors instructed
management to continue to make as much progress as possible on the proposed
transaction with the Healthcare Company, but to inform that entity of the fact
that a communication had been received from Apollo.
 
  On or about June 17, 1997, the Healthcare Company was contacted by Salomon
Brothers and advised that Alliance had received a communication from Apollo.
On June 20, 1997, the Healthcare Company released Alliance to provide
information to and engage in negotiations with Apollo through June 24, 1997.
During the period from June 20, 1997 through June 24, 1997, Alliance focused
on providing information to and conducting discussions with representatives of
Apollo. On June 24, 1997, Alliance received a written proposal from Apollo for
a recapitalization transaction involving a total consideration of $11.00 per
share, consisting of approximately $10.50 per share in cash and approximately
$0.50 per share in retained shares of Alliance.
 
  On June 26, 1997, the Board of Directors of Alliance met to receive a report
from Salomon Brothers concerning the respective transactions proposed by the
Healthcare Company and Apollo. Representatives of Salomon Brothers summarized
for the Board of Directors the activities conducted on behalf of Alliance
during the preceding approximately six months, culminating in the two
competing proposals. Salomon Brothers then provided a comparative analysis of
the two proposals. Salomon Brothers indicated that the proposal from the
Healthcare Company was conditioned on achieving pooling-of-interests
accounting treatment and tax-free treatment, while Apollo's proposal was
conditioned on recapitalization accounting treatment and obtaining financing,
and summarized the resulting impact on the risk of either transaction not
being completed. The Board of Directors of Alliance took notice that the
stock-for-stock transaction would require a large percentage of Alliance's
stockholders to provide representations as to a lack of current intention to
sell shares, and that certain of the Principal Stockholders might not be
willing to provide such a representation. Salomon Brothers indicated that,
based upon the closing price of the Healthcare Company's stock on June 25,
1997, that entity's proposal was valued at approximately $11.00 per share of
Alliance Common Stock. Salomon Brothers further provided a valuation analysis
for the "stub" equity of Alliance in Apollo's proposal. A representative of
General Electric Company ("GE") who participated pursuant to GE's Board of
Directors' observation rights (provided to GE in the agreement pursuant to
which GE purchased its Series D Preferred Stock from Alliance), indicated to
the Board that GE generally favored the proposal presented by Apollo.
 
  Based on all of the factors considered by the Board, including that the risk
of non-completion associated with the stock-for-stock proposal appeared to be
greater than that associated with the Apollo proposal, the Board of Directors
instructed management of Alliance to permit the existing exclusivity agreement
with the Healthcare Company to expire so that Alliance could engage in further
discussions with Apollo. The Board of Directors authorized management to enter
into an exclusivity agreement with Apollo which would expire not later than
July 17, 1997. In addition, the Board of Directors appointed James Buncher and
John Wallace to the Special Committee, so that the Special Committee thereupon
consisted of all four independent directors of Alliance.
 
  On June 27, 1997, the exclusivity agreement with the Healthcare Company
expired and discussions with that company were not continued. On June 28,
1997, Alliance executed an exclusivity agreement with Apollo expiring at the
close of business on July 15, 1997.

<PAGE>
 
  Beginning on June 28, 1997, and continuing for approximately two weeks,
representatives of Apollo and their legal, accounting and other advisors
conducted a detailed due diligence review of Alliance. During the same period,
Apollo and Alliance, through their respective counsel, exchanged numerous
iterations of a draft of the Recapitalization Merger Agreement. Apollo's
counsel also supplied a draft Stockholder Agreement, pursuant to which the
Principal Stockholders of Alliance would agree to vote their shares of
Alliance for the Recapitalization, against any alternative transaction and to
grant Apollo an option to acquire their shares. Related and ancillary
documentation, including the Employment Agreements and the principal terms of
the New Option Plan, was also prepared during this period.
 
  On July 9, 1997, Alliance extended the exclusivity agreement to 11:59 p.m.,
on July 17, 1997. On July 14, 1997, the Board of Directors met to address
another requested extension, received from Apollo, of the exclusivity period.
Representatives of Salomon Brothers reported that substantial progress had
been made on the draft Recapitalization Merger Agreement. They also again
summarized the requirements to achieve recapitalization accounting. The Board
of Directors authorized management to extend the exclusivity period with
Apollo through July 22, 1997.
 
  On July 16, 1997, representatives of Alliance, Apollo, their respective
counsel and Salomon Brothers met at Alliance's offices in Anaheim, California
in an attempt to resolve remaining open issues in the draft Recapitalization
Merger Agreement. On July 17, 1997, Alliance extended the exclusivity period
through 11:59 p.m. on July 22, 1997.
 
  From July 17, 1997 through July 22, 1997, representatives of Alliance,
Salomon Brothers and Apollo contacted certain of Alliance's large,
institutional stockholders in order to apprise them of the terms of the
proposed transaction. Further, it was explained to the institutional
stockholders that Apollo had required, as a condition to executing the
Recapitalization Merger Agreement with Alliance, that at least a majority of
the outstanding Alliance Common Stock be subject to the Stockholder Agreement.
Representatives of the institutional holders and their counsel submitted
requests for a number of changes to the Stockholder Agreement, which was
finalized on July 23, 1997.
 
  On July 22, 1997, the Board of Directors met to consider the proposed
Recapitalization Merger Agreement. Mr. Zehner and Mr. Pino summarized for the
Board of Directors the status of the Recapitalization Merger Agreement and the
Stockholder Agreement. Salomon Brothers then delivered its presentation (and
subsequently summarized the terms of the proposed financing and the pro forma
capital structure in connection with the Recapitalization), and Salomon
Brothers rendered its opinion that the consideration to be received and
retained by holders of Alliance Common Stock in the proposed Recapitalization
is fair, from a financial point of view, to such stockholders.
 
  The Special Committee met separately to consider the proposed Employment
Agreements to be entered into by Alliance with each of Mr. Zehner and Mr. Pino
in connection with the execution of the Recapitalization Merger Agreement,
such agreements to become effective when and if the Recapitalization is
consummated. Representatives of Irell & Manella LLP indicated that such
Employment Agreements appeared to be customary in form and provided salary,
bonus and termination benefits consistent with past levels for the affected
executives. The Special Committee rejoined the full Board meeting and
unanimously determined to recommend the execution of the Recapitalization
Agreement and related definitive documentation to the Board of Directors. The
Board of Directors of Alliance thereupon unanimously approved the
Recapitalization Agreement in substantially the form summarized to the Board
of Directors and authorized management to execute it.
 
  On July 23, 1997, Alliance extended the exclusivity period with Apollo
through 11:59 p.m. that day. On the same day, final points in the
Recapitalization Agreement and ancillary documents were resolved, and the
Recapitalization Merger Agreement was executed. Similarly, on that date Apollo
and the other parties to the Stockholder Agreement executed that agreement.
Later that day, Alliance and the Investor issued a press release announcing
the transaction.
 
  Alliance and the Investor entered into Amendment No. 1 to the
Recapitalization Merger Agreement as of August 13, 1997.
 
                                      37

  Amendment No. 2 to the Recapitalization Merger Agreement was entered into as
of October 13, 1997. The purpose of Amendment No. 2 was to amend the
Recapitalization Merger Agreement to reflect the retention of certain
outstanding stock options held by the officers of Alliance. See "THE
RECAPITALIZATION--Interests of Certain Persons in the Recapitalization."
 
  The Recapitalization Merger Agreement, as executed on July 23, 1997,
contemplated that in connection with the Recapitalization, Alliance would
consummate the acquisition of all of the outstanding shares of Three Rivers
Holding Corp., a company wholly-owned by Apollo, which is the owner of all of
the outstanding shares of SMT (the "SMT Acquisition"). Early in November 1997
it became apparent that recapitalization accounting treatment would not be
available with respect to the Recapitalization if the SMT Acquisition were
consummated in connection with the Recapitalization.
 
  Accordingly, Alliance engaged in discussions with Apollo, the underwriters
that had been consulted in connection with the issuance of the Notes and the
banks that had been contacted to provide the financing under the Credit
Agreement to determine how the Recapitalization could be accomplished without
also consummating the SMT Acquisition at the same time. The underwriters and
banks indicated to Alliance that if Alliance did not accomplish the SMT
Acquisition in connection with the Recapitalization, Alliance would need to
obtain additional equity financing in order to be able to obtain the debt
financing needed to accomplish the Recapitalization. Alliance and Apollo
discussed how such additional equity capital could be raised. Apollo indicated
that it would be willing to provide some additional equity (approximately $3
million) in exchange for additional Alliance Common Stock, but indicated that
the balance of the required additional equity would have to be in the form of
preferred stock. Accordingly, Alliance agreed to issue the Series F Preferred
Stock to Apollo because additional equity financing was required to consummate
the Recapitalization. Representatives of Alliance and Apollo engaged in
negotiations with respect to the terms of the Series F Preferred Stock as well
as the terms of Amendment No. 3 to the Recapitalization Merger Agreement,
which would amend the Recapitalization Agreement to reflect the proposed
changes in the structure of the Recapitalization.
 
  On November 10, 1997, the Board of Directors met to consider Amendment No. 3
to the Recapitalization Merger Agreement, which provides that: (i) Alliance
would not consummate the SMT Acquisition in connection with the
Recapitalization; (ii) the Actual Retained Shares Number would be reduced from
727,273 to 411,358; and (iii) Apollo would purchase $15 million of a new issue
of Alliance's Series F Preferred Stock as part of the financing of the
Recapitalization. In connection with such meeting of the Board of Directors,
Salomon Brothers reconfirmed its opinion in writing that the Recapitalization
(taking into account the effect of Amendment No. 3 to the Recapitalization
Merger Agreement) is fair to holders of Alliance Common Stock from a financial
point of view. The Board of Directors unanimously approved Amendment No. 3 to
the Recapitalization Merger Agreement. Alliance and the Investor entered into
Amendment No. 3 as of November 10, 1997. The Board of Directors considered the
terms and preferences associated with the Series F Preferred Stock
(principally the effect of the issuance of the Series F Preferred Stock on the
value of the Alliance Common Stock to be retained by existing stockholders) in
reaching its decision to approve Amendment No. 3 to the Recapitalization
Merger Agreement. However, because the issuance of the Series F Preferred
Stock would not occur if the Recapitalization does not occur, the Board of
Directors did not evaluate the terms and preferences of the Series F Preferred
Stock independent of the Recapitalization.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS; REASONS FOR THE RECAPITALIZATION
 
  At its meetings on July 22, 1997 and November 10, 1997, the Board of
Directors unanimously approved the Recapitalization Merger Agreement and
determined, among other things, that the Recapitalization Merger Agreement is
fair to and in the best interests of Alliance's stockholders and that
Alliance's stockholders approve the Recapitalization Merger Agreement. In
reaching these conclusions, the Board of Directors consulted with Salomon
Brothers and Alliance's legal counsel and considered, among other things, the
unanimous recommendation of the Special Committee that the Company execute the
Recapitalization Merger Agreement and the following factors:
 
(A) A balancing of the risks and benefits of the Recapitalization against the
    risks and benefits of the other strategic alternatives available to
    Alliance, including continuing as an independent entity. Of the strategic
 
                                      38
<PAGE>
 
   alternatives available to Alliance, the Recapitalization was determined by
   the Board of Directors to be the alternative which would yield the best
   results to the stockholders of Alliance from a financial point of view.
   First, the Recapitalization was, on balance, the most favorable acquisition
   proposal received by Alliance since it initiated a search for an
   investor/partner to assist in taking advantage of consolidation
   opportunities in the MRI marketplace. Second, the Recapitalization was
   determined to be more favorable to stockholders than Alliance continuing as
   an independent entity because Alliance's future growth prospects as an
   independent entity could be limited inasmuch as Alliance did not have the
   ability, as an independent entity, to fully take advantage of consolidation
   opportunities in the MRI marketplace. See "--Background of the
   Recapitalization." The Board of Directors also considered that a
   substantially all cash transaction, such as the Apollo transaction,
   provided superior liquidity to Alliance's stockholders.
 
(B) That the consideration to be paid and retained in the Recapitalization,
    valued at $11.00 per share of Alliance Common Stock, represents a premium
    for Alliance Common Stock of approximately 7.3% over the closing price of
    $10.25 per share of Alliance Common Stock on July 22, 1997, the trading
    day preceding the announcement of the proposed Recapitalization. The Board
    of Directors considered the value of the "stub equity" to be retained by
    stockholders of Alliance in determining the value of the consideration
    provided by the Recapitalization, and considered the fact that the "stub
    equity" to be retained would likely not be as marketable or liquid as
    Alliance Common Stock prior to the Recapitalization; however, the Board
    considered that this disadvantage was offset by the provision of a
    substantial amount of liquidity in the closing of the Recapitalization.
    The Board of Directors considered that shares of Alliance Common Stock
    have traded as low as $2.00 per share within the last two years and as low
    as $6 3/8 per share during the second quarter of 1997, meaning that the
    Recapitalization offered a substantial premium to stockholders compared to
    recent historical price levels of Alliance Common Stock.
 
(C) The written opinion of Salomon Brothers to the effect that, based upon and
    subject to various considerations (and the analyses presented to the Board
    of Directors of Alliance underlying such opinion) set forth in such
    opinion, as of November 10, 1997, the consideration to be received and
    retained by Alliance's stockholders in the Recapitalization is fair, from
    a financial point of view, to such stockholders. See "--Opinion of
    Financial Advisor."
 
(D) The terms and conditions of the Recapitalization Merger Agreement and
    related matters, including closing conditions, terms of the Series F
    Preferred Stock, termination rights, the requirement that Alliance pay
    termination fees to the Investor under certain circumstances, the cash-out
    of Alliance stock options and Alliance's and the Investor's
    representations and warranties, all of which were the product of arm's
    length negotiations in which Alliance was assisted by its financial
    advisor, Salomon Brothers and its legal counsel, Irell & Manella LLP. See
    "CERTAIN PROVISIONS OF THE RECAPITALIZATION MERGER AGREEMENT."
 
(E) The fees and expenses to be paid to an affiliate of Apollo in
    consideration for (i) arranging the transactions contemplated by the
    Recapitalization Agreement (including the financing thereof) and (ii) the
    agreement of an affiliate of Apollo to provide financial advisory and
    other management services after consummation of the Recapitalization,
    which include, in addition to reimbursement of out-of-pocket expenses, a
    fee of $2.5 million in connection with the Recapitalization and related
    transactions, a financing fee of $0.6 million in connection with the
    issuance of the Series F Preferred Stock and an annual fee of $0.5 million
    for management and other financial advisory services to be provided to
    Alliance after consummation of the Recapitalization.
 
(F) The terms and conditions of the Stockholder Agreement, pursuant to which,
    among other things, the Principal Stockholders owning approximately 54.4%
    of the issued and outstanding shares of Alliance Common Stock
    (approximately 66.0% assuming the exercise by such Principal Stockholders
    of all of their securities convertible into or exercisable for shares of
    Alliance Common Stock) (i) have agreed to vote and have granted a related
    proxy to vote their shares of Alliance Common Stock in favor of the
    Recapitalization Merger Agreement, (ii) have granted to the Investor the
    option to acquire all shares of Alliance Common Stock owned by such
    stockholders at $11.00 per share in cash and (iii) have agreed to convert
    or exercise all of their securities that are convertible into or
    exercisable for shares of Alliance Common Stock to the
 
                                      39
<PAGE>
 
   extent that such Principal Stockholders receive notice of exercise of the
   Option. The Board of Directors considered that the Stockholder Agreement
   effectively provided the Investor with a "lock-up" of Alliance and weighed
   that against the overall benefits of the Recapitalization.
 
(G) That the proposed structure of the Recapitalization treats all
    stockholders equally by giving all stockholders the opportunity to receive
    cash for their shares or to retain shares of Alliance Common Stock
    (subject to proration).
 
  The foregoing discussion of the information and factors considered by the
Board of Directors is not intended to be exhaustive, but includes all material
factors considered by the Board of Directors. In reaching its determination to
approve the Recapitalization Merger Agreement, and in view of the variety of
factors considered by the Board of Directors in connection with its evaluation
of the Recapitalization Merger Agreement, the Board of Directors did not
assign any relative or specific weights to the various factors considered by
it nor did it specifically characterize any factors as positive or negative
(except as described above). In addition, individual directors may have given
different weights to different factors and may have viewed certain factors
more positively or negatively than others.
 
  The recommendation by the Board of Directors that Alliance's stockholders
approve the Recapitalization Merger Agreement is not a recommendation as to
whether stockholders should retain shares of Alliance Common Stock.
 
OPINION OF FINANCIAL ADVISOR
 
  Alliance retained Salomon Brothers pursuant to a letter agreement dated June
6, 1997 (the "Engagement Letter") to act as its financial advisor in
connection with, among other things, a possible combination or sale
transaction involving Alliance. Pursuant to the Engagement Letter, Salomon
Brothers rendered financial advisory services relating to Alliance in
connection with the Recapitalization. Salomon Brothers rendered an opinion to
the Board of Directors on July 22, 1997, that the consideration to be received
and retained by the holders of Alliance Common Stock in the Recapitalization
(pursuant to the terms of the Recapitalization Merger Agreement as originally
executed, without reflecting the effect of any amendments thereto) is fair to
such holders from a financial point of view. Salomon Brothers' opinion was
reconfirmed in writing as of November 10, 1997.
 
  The full text of the Salomon Brothers fairness opinion dated as of November
10, 1997, which sets forth the assumptions made, general procedures followed,
matters considered and limits on the review undertaken, is attached as Annex C
to this Proxy Statement/Prospectus. This opinion is substantially similar to
the opinion rendered on July 22, 1997, and Stockholders are urged to read this
opinion in its entirety. The Salomon Brothers opinion is directed only to the
fairness, from a financial point of view, to the holders of Alliance Common
Stock of the consideration to be received and retained by such holders in the
Recapitalization and does not address Alliance's underlying business decision
to effect the Recapitalization or constitute a recommendation to any holder of
Alliance Common Stock as to how such stockholder should vote with respect to
the Recapitalization Merger Agreement and the Recapitalization, or what
election such holder should make with respect to the retention of such
holder's shares of Alliance Common Stock. The summary of the Salomon Brothers
opinion set forth below is qualified in its entirety by reference to the full
text of such opinion attached as Annex C. STOCKHOLDERS ARE URGED TO READ THE
SALOMON BROTHERS OPINION IN ITS ENTIRETY.
 
  In connection with rendering its opinion, Salomon Brothers reviewed and
analyzed the following: (i) the Recapitalization Merger Agreement (including
the amendments thereto); (ii) certain publicly available information
concerning Alliance, including the Annual Reports on Form 10-K for each of the
years in the three-year period ended December 31, 1996 and the Quarterly
Report on Form 10-Q for the quarter ended September 30, 1997; (iii) certain
other internal information, primarily financial in nature concerning the
business and operations of Alliance furnished to it by Alliance for purposes
of its analysis; (iv) certain publicly available information concerning the
trading of, and the trading market for, the Alliance Common Stock; (v) certain
publicly available information with respect to certain other companies that
Salomon Brothers believed to be comparable to Alliance and the trading markets
for certain of such other companies' securities; and (vi) certain
 
                                      40
<PAGE>
 
publicly available information concerning the nature and terms of certain
other transactions that Salomon Brothers considered relevant to its inquiry.
Salomon Brothers also considered such other information, financial studies,
analyses, investigations and financial, economic and market criteria that it
deemed relevant. Salomon Brothers also discussed the foregoing, as well as
other matters it believed relevant to its inquiry, with the management of
Alliance and officers of the Investor.
 
  In its review and analysis and in arriving at its opinion, Salomon Brothers
assumed and relied upon the accuracy and completeness of all of the financial
and other information provided to it or publicly available and neither
attempted independently to verify nor assumed any responsibility for verifying
any of such information. Salomon Brothers did not conduct a physical
inspection of any of the properties or facilities of Alliance, nor did it make
or obtain or assume any responsibility for making or obtaining any independent
evaluations or appraisals of any of such properties or facilities. With
respect to projections, Salomon Brothers assumed that they had been reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the management of Alliance and officers of the Investor as to the
future financial performance of Alliance. Salomon Brothers expressed no view
with respect to such projections or the assumptions on which they were based.
Salomon Brothers assumed that the conditions precedent to the Recapitalization
Merger contained in the Recapitalization Merger Agreement would be satisfied
and the Recapitalization would be consummated in accordance with the terms of
the Recapitalization Merger Agreement.
 
  In conducting its analysis and arriving at its opinion as expressed herein,
Salomon Brothers considered such financial and other factors as it deemed
appropriate under the circumstances including, among others, the following:
(i) the historical and current financial position and results of operations of
Alliance; (ii) the business prospects of Alliance; (iii) the historical and
current market for the Alliance Common Stock and for the equity securities of
certain other companies that Salomon Brothers believed to be comparable to
Alliance; and (iv) the nature and terms of certain other acquisition
transactions that Salomon Brothers believed to be relevant. Salomon Brothers
also took into account its assessment of general economic, market and
financial conditions as well as its experience in connection with similar
transactions and securities valuation generally. Salomon Brothers also
considered the process that resulted in the negotiation of the
Recapitalization Merger Agreement, including discussions with other potential
acquirors. The Salomon Brothers opinion necessarily was based upon conditions
as they existed and could be evaluated on the date thereof and Salomon
Brothers assumed no responsibility to update or revise its opinion based upon
circumstances or events occurring after such date. Salomon Brothers' opinion
did not constitute an opinion or imply any conclusion as to the likely trading
range for shares of the Alliance Common Stock following consummation of the
Recapitalization. Salomon Brothers' opinion was for the sole benefit of
Alliance (including its management and directors) in its consideration of the
Recapitalization and was, in any event, limited to the fairness, from a
financial point of view, of the consideration to be received and retained by
the holders of Alliance Common Stock in the Recapitalization and did not
address Alliance's underlying business decision to effect the Recapitalization
or constitute a recommendation to any holder of Alliance Common Stock as to
how such holder should vote with respect to the Recapitalization Merger
Agreement and the Recapitalization, or what election such holder should make
with respect to the retention of such holder's shares of Alliance Common
Stock.
 
  Salomon Brothers has consented to the inclusion in this Proxy
Statement/Prospectus of its fairness opinion attached as Annex C and the
description of the Salomon Brothers fairness opinion contained herein. Salomon
Brothers has advised the Board of Directors that, based on an express
disclaimer in the Engagement Letter, Salomon Brothers does not believe that
any person (including a stockholder of Alliance), other than Alliance or the
Board of Directors, has a legal right to rely upon its fairness opinion to
support any claims against Salomon Brothers arising under applicable state law
and that, should any such claims be brought against Salomon Brothers by any
such person, this assertion will be raised as a defense. In the absence of
applicable state law authority, the availability of such a defense will be
resolved by a court of competent jurisdiction. Resolution of the question of
the availability of such a defense, however, will have no effect on the rights
and responsibilities of the Board of Directors under applicable state law and
the availability of such a state law defense to Salomon Brothers
 
                                      41
<PAGE>
 
would not have any effect on the rights and responsibilities of either Salomon
Brothers or the Board of Directors under the federal securities laws.
 
  In connection with the delivery of its fairness opinion, Salomon Brothers
made a presentation to the Board of Directors on July 22, 1997, with respect
to certain financial analyses performed by Salomon Brothers in evaluating the
consideration to be received and retained in the Recapitalization by the
holders of Alliance Common Stock. The following is a summary of Salomon
Brothers' July 22 presentation.
 
  Overview of Recapitalization. As part of its presentation, Salomon Brothers
provided an overview of the Recapitalization and of the events leading up to
the negotiation of the terms of the transaction. In this part of the
presentation, the material terms of the transaction and the background of
events described in detail elsewhere in this Proxy Statement/Prospectus were
summarized. In connection with its description of the terms of the
Recapitalization, Salomon Brothers analyzed the consideration to be received
and retained by the holders of shares of Alliance Common Stock. In analyzing
the value of the consideration to be received and retained, Salomon Brothers
calculated the pro rata per share cash value of the consideration based on the
$11.00 per share cash conversion of the maximum number of shares of Alliance
Common Stock (in accordance with the terms of the draft Recapitalization
Merger Agreement dated July 22, 1997, without taking into account Amendments
Nos. 1, 2 and 3 thereto), which resulted in a deemed per share cash value of
the consideration equal to $10.43 (assuming 10,943,138 shares of Alliance
Common Stock outstanding, the conversion of Alliance's Series C and Series D
convertible preferred stock into 3,077,520 shares of Alliance Common Stock
prior to the consummation of the Transactions and that the outstanding
warrants and options would receive 100% cash consideration equal to the Net
Amount (as defined below)). Salomon Brothers then analyzed the "stub" equity
to be retained by the holders of Alliance Common Stock. Based on projected
EBITDA for the Company for 1998, and applying a range of multiples of EBITDA
of 5.5x to 6.5x and a range of discount rates, and based on the Company's
projected weighted average cost of capital, of 15% to 25%, Salomon Brothers
derived a pro rata per share value of the "stub" equity consideration retained
by holders of shares of Alliance Common Stock equal to between $0.41 and
$0.81, and centered around $0.60. Based on this analysis, Salomon Brothers
used a valuation of $11.00 per share ($10.43 in cash and $0.57 in stock) for
the consideration received and retained by holders of shares of Alliance
Common Stock in the Recapitalization for purposes of its other analyses
discussed below.
 
  Historical Price and Volume Analysis. Salomon Brothers reviewed certain
information concerning the trading price and volume of shares of Alliance
Common Stock from January 1, 1996 through July 18, 1997. Salomon Brothers
noted that the shares of Alliance Common Stock had (i) ranged in price between
$4.00 per share and $11.125 per share in the last twelve months and traded
lightly during such period, (ii) weighted average trading prices between
approximately $7.00 and $9.00 per share over the past twelve months and (iii)
increased in price per share in the past approximately two months, which could
be attributable in part to speculation concerning takeover activity in the
diagnostic imaging industry in general and, possibly, Alliance in particular.
Salomon Brothers also noted that from January 1, 1996 through July 18, 1997,
the price of Alliance Common Stock had outperformed the Nasdaq Composite Index
and an index reflecting the average of the common stock prices of several
comparable companies in the diagnostic imaging sector.
 
  Analysis of Selected Publicly-Traded Comparable Companies. Salomon Brothers
reviewed certain publicly available financial, operating and stock market
information for Alliance, SMT and three other publicly traded diagnostic
imaging companies (Diagnostic Health Services, Inc., InSight Health Services
("InSight") and Medical Resources, Inc. (excluding Alliance, each of which is
a "Comparable Company," and collectively referred to as "Comparable
Companies")). Salomon Brothers considered the Comparable Companies to be
somewhat similar to Alliance, but noted that there are very few public
companies in Alliance's industry and none of these companies is identical to
Alliance. Accordingly, the analysis described below is not purely
mathematical. Rather it involves complex considerations and judgments
concerning differences in historical and projected financial and operating
characteristics of Alliance and the Comparable Companies and other factors
that could affect public trading value. Additionally, Salomon Brothers
observed that the valuation multiples in the
 
                                      42
<PAGE>
 
diagnostic imaging sector were highly variable. Salomon Brothers noted that,
in its view, the comparable company analysis was of somewhat limited utility.
 
  For Alliance and each of the Comparable Companies, Salomon Brothers
calculated, among other things, multiples of trading price (as of July 18,
1997 and as of May 23, 1997 for SMT and Alliance which was 30 days prior to
the public announcement of the acquisition of SMT by Three Rivers) to LTM
earnings per share ("EPS"), estimated calendar 1997 EPS and estimated calendar
1998 EPS, and of Firm Value (equity market capitalization plus net debt) to
LTM revenues, LTM EBITDA and LTM EBIT. (Estimated EPS was based upon First
Call Corporation consensus estimates as of July 18, 1997.)
 
  Taking into account Alliance's financial performance relative to the
Comparable Companies, Salomon Brothers derived a reference range of multiples
of Firm Value to LTM EBITDA (5.5x to 7.0x), Firm Value to 1997 EBITDA (5.0x to
6.4x) and Firm Value to 1998 EBITDA (4.5x to 5.7x) using, in particular, data
for two companies, SMT and InSight, that it viewed as the closest comparables
given their primary mobile focus. These ranges were narrower than the ranges
based solely on calculations from the public data based on subjective and
qualitative judgments applied by Salomon Brothers to such calculations to more
accurately reflect the valuation sensitivity provided by this analysis. Using
such derived range of multiples, Salomon Brothers derived a valuation range
for the Implied Equity Value per share of Alliance of $8.00 to $11.50, with
particular focus on the valuation based on the 1997 EBITDA multiples.
 
  Analysis of Selected Mergers/Acquisition Transactions. Salomon Brothers also
analyzed certain publicly available financial, operating and stock market
information for nine selected merger or acquisition transactions in the
diagnostic imaging industry over the past three years (Apollo's then pending
tender offer to acquire SMT later in 1997; HEALTHSOUTH Corp.'s 1996
acquisition of Health Images, Inc.; Medical Resources, Inc.'s 1996 acquisition
of NMR of America, Inc.; USDL's 1996 acquisition of Medical Imaging Centers of
America, Inc.; the 1996 merger of American Health Corp. and Maxum Health
Corp.; USDL's 1996 acquisition of Meditek Health Corp; USDL's 1996 acquisition
of U.S. Imaging, Inc.; USDL's 1996 acquisition of Allegheny MRI, Inc.; and
Health Images, Inc.'s 1994 acquisition of MedAlliance, Inc.). Salomon Brothers
considered the precedent mergers and acquisition transactions to be reasonably
comparable to the Recapitalization, but not identical to the Recapitalization.
Accordingly, the analysis described below is not purely mathematical. Rather
it involves complex considerations and judgments concerning differences in
historical and projected financial and operating characteristics of Alliance,
the companies involved in the precedent merger and acquisition transactions
and other factors that could affect the private market valuation. For each
such transaction, Salomon Brothers calculated the multiples of, among other
things, Firm Value to LTM revenue, Firm Value to LTM EBITDA, Firm Value to LTM
EBIT and offer price to LTM EPS.
 
  Giving special weight to the SMT transaction, Salomon Brothers derived a
reference range of multiples of Firm Value to LTM EBITDA (5.5x to 6.5x), Firm
Value to 1997 EBITDA (5.2x to 6.2x) and Firm Value to 1998 EBITDA (4.6x to
5.5x). This range was narrower than the range based solely on calculations
from the public data based on certain subjective and qualitative judgments
applied by Salomon Brothers to such public data. Using such derived range of
multiples, Salomon Brothers derived a valuation range for the Implied Equity
Value per share of Alliance of $9.00 to $11.00, with particular focus on the
valuation based on the 1997 EBITDA multiples.
 
  Discounted Cash Flow Analysis. Salomon Brothers performed a discounted cash
flow analysis of the projected unlevered free cash flows of Alliance for the
fiscal years 1997 through 2001 based on financial projections provided by
management of Alliance. In conducting the discounted cash flow analysis,
Salomon Brothers utilized discount rates ranging from 11.5%to 13.5% (with
particular focus on discount rates of 12.0% to 13.0%), that were derived by
using the median unlevered beta for the Comparable Companies and certain other
assumptions about capital structure, and market risk, and terminal multiples
of year 2001 EBITDA ranging from 4.5x to 6.5x (with particular focus on
terminal multiples of 5.0x to 6.0x). From this analysis, Salomon
 
                                      43
<PAGE>
 
Brothers derived a present value of the firm range of $197.2 million to $240.0
million for Alliance at June 30, 1997, from which Salomon Brothers derived a
valuation range of the implied present value per share of $9.00 to $11.50.
 
  In connection with the opinion dated as of November 10, 1997, Salomon
Brothers performed procedures to update, as necessary, certain of the analyses
described above and reviewed the assumptions on which such analyses were based
and the factors considered in connection therewith, as well as the terms of
the Recapitalization, as modified by Amendment Nos. 1, 2 and 3 to the
Recapitalization Merger Agreement. See "THE RECAPITALIZATION--Background of
the Recapitalization." In performing these updating analyses, Salomon Brothers
utilized a valuation of $11.00 per share of Alliance Common Stock (consisting
of $10.68 in cash and $0.32 in retained shares) to reflect the modified terms
of the Recapitalization Merger Agreement. Salomon Brothers did not perform any
type of analysis other than those described above in updating its opinion.
 
  The foregoing summary does not purport to be a complete description of the
analyses performed by Salomon Brothers or of its presentations to the Board of
Directors. The preparation of financial analyses and fairness opinions is a
complex process involving subjective judgments and is not necessarily
susceptible to partial analysis or summary description. Salomon Brothers made
no attempt to assign specific weight to particular analyses or factors
considered, but rather made qualitative judgments as to the significance and
relevance of the analyses and factors considered. Accordingly, Salomon
Brothers believes that its analyses (and the summary set forth above) must be
considered as a whole, and that selecting portions of such analyses and of the
factors considered by Salomon Brothers, without considering all of such
analyses and factors, could create a misleading or incomplete view of the
processes underlying the analyses conducted by Salomon Brothers and its
opinion. In its analyses, Salomon Brothers made numerous assumptions with
respect to Alliance, industry performance, general business, economic, market
and financial conditions and other matters, many of which are beyond the
control of Alliance. Any estimates contained in Salomon Brothers' analyses are
not necessarily indicative of actual values or predictive of future results or
values, which may be significantly more or less favorable than those suggested
by such analyses. Estimates of values of companies do not purport to be
appraisals or necessarily to reflect the prices at which companies may
actually be sold. Because such estimates are inherently subject to
uncertainty, Salomon Brothers does not assume responsibility if future results
or actual values differ materially from the estimates. Salomon Brothers'
analyses were prepared solely as part of Salomon Brothers' analysis of the
fairness of consideration to be received and retained by holders of Alliance
Common Stock in the Recapitalization and were provided to the Board of
Directors of Alliance in that connection. The opinion of Salomon Brothers was
one of the factors taken into consideration by the Board of Directors of
Alliance in making its determination to approve the Recapitalization.
 
  Salomon Brothers is an internationally recognized investment banking firm
engaged in, among other things, the valuation of businesses and their
securities in connection with mergers and acquisitions, restructurings,
leveraged buyouts, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. Salomon Brothers has
previously rendered certain investment banking and financial advisory services
to Alliance and to certain affiliates of the Investor, for which it has
received customary compensation. In addition, in the ordinary course of its
business, Salomon Brothers may actively trade the debt and equity securities
of Alliance for its own account and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.
In addition, since the time of rendering its fairness opinion to the Board of
Directors, Salomon Brothers has been invited and has agreed to participate as
syndication agent and as a Lender (as defined in the Credit Agreement) under
the Credit Agreement, and to participate as co-manager in the Offering, to
fund the cash payments to be made in the Recapitalization, and will receive
customary compensation. See "SOURCES AND AMOUNT OF FUNDS."
 
  Pursuant to the Engagement Letter, Alliance will pay Salomon Brothers the
following fees: (a) $100,000, which was earned upon Alliance's execution of
the Recapitalization Merger Agreement; plus (b) an additional
 
                                      44
<PAGE>
 
fee of $400,000, which was earned upon the initial submission of Salomon
Brothers' fairness opinion to the Board of Directors on July 22, 1997; plus
(c) an additional fee of approximately $2.4 million, which is contingent upon
the consummation of the Recapitalization. Alliance has also agreed to
reimburse Salomon Brothers for its reasonable travel and other out-of-pocket
expenses incurred in connection with its engagement (including the reasonable
fees and disbursements of its counsel) and to indemnify Salomon Brothers
against certain liabilities and expenses relating to or arising out of its
engagement, including certain liabilities under the Federal securities laws.
 
  As noted under the caption "THE RECAPITALIZATION--Recommendation of the
Board of Directors; Reasons for the Recapitalization," the fairness opinion of
Salomon Brothers was one of several factors considered by the Board of
Directors in determining to approve the Recapitalization Agreement and the
Recapitalization. The amount of consideration payable in the Recapitalization
was determined by arms' length negotiations between the Investor and Alliance,
in consultation with their respective financial advisors and other
representatives, and was not established by such financial advisors.
 
INTERESTS OF CERTAIN PERSONS IN THE RECAPITALIZATION
 
  In considering the recommendation of the Board of Directors with respect to
the Recapitalization Merger Agreement, stockholders should be aware that
certain members of management of Alliance at the time of the Board of
Director's approval of the Recapitalization Merger Agreement had, and
currently have, certain interests which may present them with potential
conflicts of interest in connection with the Recapitalization. In addition,
each member of the Board of Directors (including the members of the Special
Committee) holds stock options which will be accelerated as a result of the
Recapitalization. The interests of executive officers and the directors of
Alliance in the Recapitalization are summarized below. The Board of Directors
was aware of these interests and considered them in addition to the other
matters described under "--Background of the Recapitalization," "--
Recommendation of the Board of Directors; Reasons for the Recapitalization"
and "CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS."
 
  Executive Officers of Alliance Following the Recapitalization. All of the
current executive officers of Alliance will remain executive officers of
Alliance following the Recapitalization. Messrs. Zehner and Pino have entered
into Employment Agreements with Alliance, effective as of the Recapitalization
Effective Time, which will replace their current employment agreements. In
addition, Messrs. Zehner and Pino will continue as directors of Alliance
following the Recapitalization. See "MANAGEMENT" and "CERTAIN RELATED
AGREEMENTS--Employment Agreements and Agreement Not to Compete."
 
  Alliance's Amended and Restated 1991 Stock Option Plan. Certain executive
officers and directors of Alliance have previously received stock options
pursuant to Alliance's Amended and Restated 1991 Stock Option Plan (the "1991
Plan"). Notwithstanding the vesting schedule otherwise applicable to such
stock options, as a result of the Recapitalization, substantially all such
stock options will become fully vested. At the Recapitalization Effective
Time, each outstanding option will either (i) pursuant to agreements entered
into between Alliance and certain officers of Alliance, remain outstanding
following the Recapitalization Effective Time or (ii) be canceled in exchange
for an amount in cash, payable at the time of such cancellation, equal to the
product of (x) the number of shares of Alliance Common Stock subject to such
option immediately prior to the Recapitalization Effective Time and (y) the
excess of $11.00 over the per share exercise price of such option. The
following table shows, for each of the executive officers and directors of
Alliance, (i) the number of options granted to such individual since December
31, 1996, (ii) the total number of outstanding options held by such individual
as of the date of this Proxy Statement/Prospectus, (iii) the value of such
individual's options that will be cancelled in exchange for cash (before
federal and state income taxes) at the Recapitalization Effective Time and
(iv) the aggregate value of all the stock options held by such individual. The
value of each option was calculated by subtracting the exercise price per
share of Alliance Common Stock from the Cash Merger Price.

* The total value of options includes the following amounts to be paid to the
  option holder at the Recapitalization Effective Time, to the extent that
  such options are not exercised prior thereto: Mr. Zehner $3,601,978; Mr.

  outstanding and substantially all of such options will be fully vested.
 
  All of the options granted in 1997 were granted on March 25, 1997, with an
exercise price of $6.5625 per share, except for the options granted to Mr.
Hayes which were granted on May 15, 1997 with an exercise price of $7.875 per
share. The exercise price with respect to each such option is equal to the
fair market value of one share of Alliance Common Stock on the date of grant
of such option.
 
  Certain members of management will be permitted to retain certain options to
acquire 70,000 shares of Alliance Common Stock following the Recapitalization,
which options have an approximate aggregate value of $0.5 million. The terms
of the options that remain outstanding following the consummation of the
Recapitalization will not change materially, except that the provision which
specified that such options would no longer be exercisable 90 days after
termination of employment will no longer apply to certain of such options.
Alliance does not intend to redeem such options that remain outstanding for
cash at a future date.
 
  Long Term Incentive Plan. Pursuant to the terms of Alliance's Amended and
Restated Long Term Incentive Plan (the "LTIP"), at the Recapitalization
Effective Time, Alliance's executive officers will be paid the amounts (before
federal and state income taxes) earned by them pursuant to the LTIP through
the date of the Recapitalization, as set forth below:

  The LTIP was amended on July 22, 1997, immediately prior to Alliance's
entering into the Recapitalization Merger Agreement, to provide that the
participants in the LTIP will be eligible to earn (subject to satisfying the
goals set forth in the LTIP) the potential LTIP awards for 1998, not to exceed
$125,000 for all participants in
 
                                      46
<PAGE>
 
the aggregate. Absent such amendment, the LTIP would have terminated at the
Recapitalization Effective Time and the executives would not have been
eligible to earn the aggregate amount set forth in the preceding sentence.
 
  Payments Under Employment Agreements. The employment agreements for
Alliance's executive officers provide for certain benefits and rights upon the
occurrence of a "change of control." Alliance's executive officers have agreed
that the execution of the Recapitalization Merger Agreement and the
Stockholder Agreement does not, on its own, constitute a change of control for
the purposes of such employment agreements. However, the consummation of the
Recapitalization will constitute a "change of control" for the purposes of
such employment agreements.
 
   The employment agreements for Ms. Ford and for Messrs. Andrues, Mericle,
Cullinan and Grismer provide that (i) if Alliance takes actions which
constitute Constructive Discharge (as defined in such agreements) or
terminates such executive without Just Cause (as defined in such agreements)
within one year before or one year after a change of control or (ii) the
executive quits for any reason within one year following a change of control,
then such executive shall be entitled to receive: (x) a cash amount equal to
the sum of the executive's salary at the time of termination and the
executive's target bonus for the year of termination and (y) a continuation of
benefits (including car allowance, health insurance and 401(k) plan benefits)
for a period of 12 months following termination.
 
  The employment agreements for Messrs. Zehner, Pino and White were amended on
May 15, 1997 to provide that upon the occurrence of a change in control, such
executives are entitled to receive (i) a cash amount equal to 2.5 times (two
times in the case of Mr. White) the sum of the executive's salary at the time
of the change of control and the executive's target bonus for the year in
which the change of control occurs and (ii) a continuation of benefits
(including car allowance, health insurance and 401(k) plan benefits) for a
period of 30 months (24 months in the case of Mr. White) following the change
of control. Absent the May 15, 1997 amendments, such payments would have been
made, and such benefits would have been provided, only if (i) Alliance were to
take actions which constitute Constructive Discharge (as defined in such
agreements) or to terminate such executive without Just Cause (as defined in
such agreements) within one year before or one year after the change of
control, or (ii) the executive were to quit for any reason within one year
following a change of control.
 
  All of the employment agreements discussed above prohibit the provision of
payments and benefits to the extent such payments or benefits would cause
Alliance to be unable to deduct amounts pursuant to the provisions of Section
280G of the Internal Revenue Code of 1986, as amended (the "Code"), which
imposes a limit on certain payments made by a corporation that are contingent
upon a change of control. As a result of such limits, it is estimated that the
amount of payments that Alliance will make to Messrs. Zehner, Pino and White
as a result of the consummation of the Recapitalization pursuant to the
employment agreements (prior to federal and state income taxes) will be
reduced to equal $850,000, $500,000 and approximately $420,000, respectively.
 
  Agreements Not to Compete. Alliance, the Investor and Messrs. Zehner and
Pino have entered into an agreement that contains, among other things,
covenants not to compete with Alliance. Pursuant to these covenants, Alliance
will be required under certain circumstances to make payments to Messrs.
Zehner and Pino following the termination of their employment with Alliance.
See "CERTAIN RELATED AGREEMENTS--Employment Agreements and Agreement Not to
Compete."
 
  Indemnification and Insurance. All rights to indemnification and exculpation
(including the advancement of expenses) from liabilities for acts or omissions
occurring at or prior to the Recapitalization Effective Time in effect as of
the date of the Recapitalization Merger Agreement in favor of the current or
former directors, officers and employees of Alliance, shall continue in full
force and effect without amendment in accordance with their terms for a period
of not less than five years after the Recapitalization Effective Time.
Currently, Alliance indemnifies directors and officers to the fullest extent
permitted by law with respect to any claims or proceedings relating to or
arising out of their service as an officer or director. Directors and officers
have the right to be paid by Alliance for expenses incurred in defending any
such claim or proceeding in advance of its final disposition.
 
                                      47
<PAGE>
 
  In addition, for a period of at least five years after the Recapitalization
Effective Time, Alliance has agreed to maintain in effect standard policies of
directors' and officers' liability insurance in an aggregate coverage amount
not less than the coverage amounts maintained by Alliance as of the date of
the Recapitalization Merger Agreement, and including coverage with respect to
claims arising from facts or events which occurred before the Recapitalization
Effective Time to the extent available.
 
  New Option Plan. The Company intends to adopt the New Option Plan as of the
Recapitalization Effective Time. See "CERTAIN RELATED AGREEMENTS--The New
Option Plan."
 
EFFECT OF THE RECAPITALIZATION
 
  Pursuant to the Recapitalization Merger Agreement, Newco will be merged with
and into Alliance. At the Recapitalization Effective Time, the separate
corporate existence of Newco will cease, Alliance will continue as the
surviving corporation, the shares of common stock of Newco will be converted
into 3,632,222 shares of Alliance Common Stock, 411,358 shares of Alliance
Common Stock will be retained by Alliance's existing stockholders and the
balance of the shares of Alliance Common Stock issued and outstanding
immediately prior to the Recapitalization Effective Time (other than
Dissenting Shares) will be converted into the right to receive $11.00 in cash.
 
  The Recapitalization Merger Agreement provides that 411,358 shares of
Alliance Common Stock, or approximately 3% of the presently issued and
outstanding shares of Alliance Common Stock (assuming conversion of all shares
of preferred stock of Alliance), will be retained by Alliance's existing
stockholders and the remainder, approximately 97 % of the issued and
outstanding shares of Alliance Common Stock (assuming conversion of all shares
of preferred stock of Alliance and assuming there are no Dissenting Shares)
will be converted into the right to receive $11.00 per share in cash. The
Recapitalization Merger Agreement provides that an aggregate of 411,358 shares
of Alliance Common Stock will be retained by Alliance's existing stockholders.
Each stockholder of Alliance may elect to retain shares of Alliance Common
Stock by following the procedures set forth in "THE RECAPITALIZATION--
Proration." If Alliance's stockholders elect to retain more or less than
411,358 shares of Alliance Common Stock, the number of shares to be retained
will be prorated as described in "THE RECAPITALIZATION--Proration."
Consequently, at the time holders of shares of Alliance Common Stock vote in
respect of the Recapitalization Merger Agreement and decide whether to elect
to retain shares of Alliance Common Stock, they will not know if they will be
entitled to retain all of the shares they elect to retain or if they will be
required to retain shares of Alliance Common Stock which they do not elect to
retain. The Principal Stockholders will be entitled to participate in the
proration of the retained shares in the same manner as Alliance's other
stockholders, unless the Investor exercises the option (in which case, the
Principal Stockholders would receive cash for their shares and would not be
subject to proration). The Investor has advised the Company that it does not
currently intend to exercise the option and would do so only if a third party
sought to acquire Alliance prior to consummation of the Recapitalization or
the termination of the Recapitalization Merger Agreement. If the Investor does
exercise the options, all 411,358 of the retained shares would be prorated
among Alliance's existing public stockholders, who own approximately 34% of
the issued and outstanding shares of Alliance Common Stock (assuming the
conversion or exercise by the Principal Stockholders of all of their
securities which are convertible into or exercisable for shares of Alliance
Common Stock).
 
  Pursuant to the Recapitalization Merger Agreement, Apollo will receive a
total of 3,632,222 shares of Alliance Common Stock and 150,000 shares of
Alliance's Series F Preferred Stock. Consequently, immediately after the
Recapitalization, Alliance will have 4,043,580 shares of common stock
outstanding, of which Apollo will own 3,632,222 shares (or approximately 90%)
and Alliance's existing stockholders will own 411,358 shares (or approximately
10%). Immediately after consummation of the Recapitalization, Apollo intends
to sell 242,898 shares of Alliance Common Stock owned by Apollo to BT for
$11.00 per share (or approximately $2.7 million in the aggregate) in cash, the
amount paid to Alliance's existing stockholders for their shares of Alliance
Common Stock. In addition, options to acquire 524,545 shares of Alliance
Common Stock will be held by or issuable to management of Alliance after
consummation of the Recapitalization. Immediately after
 
                                      48
<PAGE>
 
consummation of the Transactions, Apollo also intends to sell to BT $0.9
million stated amount of the Series F Preferred Stock purchased by it for $0.9
million in cash. See "THE RECAPITALIZATION--Interests of Certain Persons in
the Recapitalization," "CERTAIN RELATED AGREEMENTS--The New Option Plan."
 
  The aggregate cash consideration to be received by Alliance's stockholders
in respect of shares of Alliance Common Stock (other than retained shares)
will be approximately $149.7 million. Assuming all securities convertible into
or exercisable for shares of Alliance Common Stock were converted or
exercised, the aggregate cash consideration to be received by Alliance's
stockholders would be approximately $161.7 million.
 
PROCEDURE FOR RETAINED SHARE ELECTION
 
  Each person who is a record holder of shares of Alliance Common Stock on or
prior to 5:00 p.m., New York City time, on the Record Date, will be entitled
to make a Retained Share Election with respect to all or any portion of his or
its shares of Alliance Common Stock. The Election Form for making a Retained
Share Election is being mailed to holders of record of shares of Alliance
Common Stock as of the Record Date, together with this Proxy
Statement/Prospectus. A RETAINED SHARE ELECTION SHALL HAVE BEEN VALIDLY MADE
ONLY IF THE EXCHANGE AGENT SHALL HAVE RECEIVED, ON OR PRIOR TO THE SPECIAL
MEETING DATE, AN ELECTION FORM, PROPERLY COMPLETED AND SIGNED IN ACCORDANCE
WITH SUCH RULES AS THE EXCHANGE AGENT MAY ESTABLISH PURSUANT TO THE
RECAPITALIZATION MERGER AGREEMENT, AND ACCOMPANIED BY EITHER (I) CERTIFICATES
FOR THE SHARES OF ALLIANCE COMMON STOCK TO WHICH SUCH ELECTION FORM RELATES,
DULY ENDORSED IN BLANK OR OTHERWISE IN FORM ACCEPTABLE FOR TRANSFER ON THE
BOOKS OF ALLIANCE, OR (II) AN APPROPRIATE NOTICE OF GUARANTEED DELIVERY OF
SUCH CERTIFICATES AS SET FORTH IN SUCH ELECTION FORM FROM A FIRM WHICH IS A
MEMBER OF A REGISTERED NATIONAL SECURITIES EXCHANGE OR OF THE NATIONAL
ASSOCIATION OF SECURITIES DEALERS, INC., OR FROM A COMMERCIAL BANK OR TRUST
COMPANY HAVING AN OFFICE OR CORRESPONDENT IN THE UNITED STATES.
Notwithstanding anything to the contrary contained herein, any Election Form
accompanied by a Notice of Guaranteed Delivery shall be deemed not validly
made if the certificate or certificates are in fact delivered to the Paying
Agent after three (3) Nasdaq SmallCap Market trading days after the date of
execution of such Notice of Guaranteed Delivery. The Exchange Agent may, with
the mutual agreement of the Investor and Alliance, make such rules as are
consistent with the Recapitalization Merger Agreement for the implementation
of the elections provided for herein as shall be necessary or desirable fully
to effect such elections.
 
REVOCATION OF RETAINED SHARE ELECTIONS
 
  Any Election Form may be revoked by the stockholder submitting such Election
Form if a written notice of revocation is received by the Exchange Agent prior
to 5:00 p.m., New York City time, on the Special Meeting Date. In addition,
all Election Forms will be revoked automatically if the Recapitalization
Merger Agreement is terminated pursuant to the terms of the Recapitalization
Merger Agreement. If an Election Form is revoked, the certificate or
certificates (or guarantees of delivery, as appropriate) for the shares of
Alliance Common Stock to which such Election Form relates will be returned by
the Exchange Agent to the stockholder submitting the same to the Exchange
Agent.
 
ROLE OF THE EXCHANGE AGENT
 
  The Exchange Agent will determine (i) whether or not Retained Share
Elections have been validly made or validly revoked and (ii) when elections
and revocations have been received by it. If the Exchange Agent determines
that any Retained Share Election was not validly made, then, subject to any
proration, such shares of Alliance Common Stock will be converted in the
Recapitalization into the right to receive the Cash Merger Price. The Exchange
Agent will also make all computations as to the allocation and the proration
described below. All determinations and calculations by the Exchange Agent
will be conclusive and binding on the holders of shares of Alliance Common
Stock.

PRORATION
 
  Pursuant to the Recapitalization Merger Agreement, if the Elected Retained
Share Number exceeds the Actual Retained Share Number, then the number of
shares of Alliance Common Stock which will be retained will be reduced by such
excess number of shares. In such event, each holder of Elected Retained Shares
shall be allocated Non-Elected Cash Shares in lieu of Elected Retained Shares
such that (after giving effect to adjustments for fractional shares) each such
holder shall be deemed to hold Non-Elected Cash Shares in an amount equal to
(x) the total number of Elected Retained Shares held by such holder less (y)
the product of (A) a fraction, the numerator of which is the Actual Retained
Share Number, and the denominator of which is the Elected Retained Share
Number, multiplied by (B) the total number of Elected Retained Shares held by
such holder.
 
  Pursuant to the Recapitalization Merger Agreement, if the Actual Retained
Share Number is greater than the Elected Retained Share Number, then the
aggregate number of shares of Alliance Common Stock which shall be converted
into the right to receive cash shall be decreased by a number of shares equal
to the excess of the Actual Retained Share Number over the Elected Retained
Share Number. In such event, each holder of Elected Cash Shares (other than
the Investor) shall be allocated a portion of the Non-Elected Retained Shares
in lieu of Elected Cash Shares (after giving effect to adjustments for
fractional shares) equal to (i) the number of Elected Cash Shares held by such
holder, multiplied by (ii) a fraction, the numerator of which is the number of
Non-Elected Retained Shares and the denominator of which is the aggregate
number of Elected Cash Shares held by all holders (other than the Investor).
 
  The following examples illustrate the potential effects of proration,
assuming 14,023,344 outstanding shares of Alliance Common Stock as of the time
of the Recapitalization (the number of shares of Alliance Common Stock
outstanding assuming conversion of all shares of preferred stock of Alliance).
 
A. HOLDER A OWNS 100 SHARES AND DOES NOT ELECT TO RETAIN ANY SHARES.
 
  (1) If Alliance's other stockholders elect to retain, in the aggregate, a
number of shares of Alliance Common Stock that is at least equal to the Actual
Retained Share Number, then Holder A would receive cash for all of its shares
of Alliance Common Stock.
 
  (2) If Alliance's other stockholders elect to retain, in the aggregate, a
number of shares of Alliance Common Stock that is less than the Actual
Retained Share Number, then Holder A would not be able to receive cash for all
100 of its shares and would be required to retain a number of Non-Elected
Retained Shares so that the aggregate number of shares to be retained by all
of Alliance's existing stockholders is equal to the Actual Retained Share
Number. However, even in the case of maximum proration (i.e., no stockholders
elect to retain shares), Holder A would be entitled to receive at least $1,078
in cash (98 shares at $11.00 per share) and would retain 2 shares of Alliance
Common Stock.
 
B. HOLDER B OWNS 100 SHARES AND ELECTS TO RETAIN ALL OF ITS SHARES.
 
  (1) If Alliance's stockholders (including Holder B) elect to retain, in the
aggregate, a number of shares of Alliance Common Stock that is less than the
Actual Retained Share Number, then Holder B would be able to retain all 100 of
its Elected Retained Shares. As described in example A.(2) above, if elections
to retain shares are received in respect of less than the Actual Retained
Share Number, non-electing stockholders would retain a number of Non-Elected
Retained Shares so that the aggregate number of shares to be retained by all
of Alliance's existing stockholders is equal to the Actual Retained Share
Number.
 
  (2) If Alliance's stockholders (including Holder B) elect to retain, in the
aggregate, a number of shares of Alliance Common Stock that is more than the
Actual Retained Share Number, then Holder B would not be able to retain all
100 of its Elected Retained Shares and would be required to receive some cash
so that the aggregate number of shares of Alliance Common Stock to be retained
by all of Alliance's existing stockholders is equal to the Actual Retained
Share Number. For example, if stockholders elect to retain 1,000,000 shares in
the aggregate, then each holder, including Holder B, would be able to retain
only approximately 43% of the shares sought to be
 
                                      50
<PAGE>
 
retained by such stockholder so that the number of shares of Alliance Common
Stock to be retained by all of Alliance's existing stockholders is equal to
the Actual Retained Share Number. Therefore, Holder B would be able to retain
only 43 Elected Retained Shares (or 43% of its 100 Elected Retained Shares)
and would receive $627 in cash (57 shares at $11.00 per share), after giving
effect to the cash payment for fractional shares. In the case of maximum
proration (i.e., all stockholders elect to retain their shares), Holder B
would be able to retain only 2 Elected Retained Shares (or 2%) and would
receive $1,078 in cash (or 98%).
 
C. HOLDER C OWNS 100 SHARES AND ELECTS TO RETAIN 50 OF ITS SHARES.
 
  (1) If Alliance's stockholders (including Holder C) elect to retain a number
of shares of Alliance Common Stock that is equal to the Actual Retained Share
Number, then Holder C would be able to retain exactly 50 of its Elected
Retained Shares and would receive $550 in cash (50 shares at $11.00 per
share).
 
  (2) If Alliance's stockholders (including Holder C) elect to retain, in the
aggregate, a number of shares of Alliance Common Stock that is more than the
Actual Retained Share Number, then Holder C would not be able to retain all 50
Elected Retained Shares and would be required to receive some cash in lieu of
some of such 50 Elected Retained Shares so that the aggregate number of shares
of Alliance Common Stock to be retained by all of Alliance's existing
stockholders is equal to (and not more than) the Actual Retained Share Number.
For example, if Alliance's stockholders elect to retain 1,000,000 shares in
the aggregate, then each stockholder, including Holder C, would be able to
retain only approximately 43% of its Elected Retained Shares so that the
aggregate number of shares of Alliance Common Stock to be retained by all of
Alliance's existing stockholders is equal to the Actual Retained Share Number.
Therefore, Holder C would be able to retain only 21 Elected Retained Shares
(or 42% of its 50 Elected Retained Shares) and would receive $869 in cash (79
shares at $11.00 per share). If the stockholders elect to retain more than
1,000,000 shares in the aggregate, then Holder C would receive fewer Elected
Retained Shares than in the example above, but would receive a greater amount
of cash.
 
  (3) If Alliance's stockholders (including Holder C) elect to retain, in the
aggregate, a number of shares less than the Actual Retained Share Number, then
Holder C would be required to retain a number of Non-Elected Retained Shares
(in addition to the 50 Elected Retained Shares) so that the aggregate number
of shares of Alliance Common Stock to be retained by all of Alliance's
existing stockholders is equal to (and not less than) the Actual Retained
Share Number. For example, if stockholders elected to retain 100,000 shares in
the aggregate, then all stockholders must collectively retain an additional
311,358 Non-Elected Retained Shares so that the aggregate number of shares of
Alliance Common Stock to be retained by all of Alliance's existing
stockholders is equal to the Actual Retained Share Number. In this example,
Holder C would be required to retain one additional Non-Elected Retained Share
(for a total of 51 Non-Elected Retained Shares) and would receive $539 in cash
(49 shares at $11 per share). The additional Non-Elected Retained Shares is
calculated by multiplying the 50 shares in respect of which Holder C wants to
receive cash by a fraction, the numerator of which is 311,358 and the
denominator of which is the total number of outstanding shares less the
100,000 shares for which an election to retain such shares is made. If the
stockholders elect to retain fewer than 100,000 Elected Retained Shares in the
aggregate, then Holder C would receive more shares than in the example above,
but would receive less cash.
 
  Fractional shares of Alliance Common Stock will not be issued in the
Recapitalization. Holders of Alliance Common Stock otherwise entitled to a
fractional share of Alliance Common Stock following the Recapitalization will
be paid cash in lieu of such fractional share determined and paid as described
under "--Fractional Shares" below.
 
  If a stockholder does not make a valid Retained Share Election prior to the
Special Meeting Date (or validly revokes such election) and receives cash as a
result of the proration procedures described above, such stockholder may
receive dividend treatment (rather than capital gain treatment) for any cash
received in the Recapitalization as a result of such proration procedures. See
"THE RECAPITALIZATION--Certain Tax Consequences of the Recapitalization--
Stockholders Receiving Cash" below.

EFFECTIVE TIME OF THE RECAPITALIZATION
 
  The Recapitalization will become effective upon the filing of a Certificate
of Merger with the Secretary of State of the State of Delaware or such later
date as is specified in such Certificate of Merger. The filing of the
Certificate of Merger for the Recapitalization will occur as soon as
practicable on or after the Special Meeting Date unless another date is agreed
to in writing by the Company and the Investor. Subject to certain limitations,
the Recapitalization Merger Agreement may be terminated by either party if,
among other reasons, the Recapitalization has not been consummated on or
before December 31, 1997. See "CERTAIN PROVISIONS OF THE RECAPITALIZATION
MERGER AGREEMENT--Conditions" and "CERTAIN PROVISIONS OF THE RECAPITALIZATION
MERGER AGREEMENT--Termination of the Recapitalization Merger Agreement."
 
RETENTION OF SHARES; PROCEDURES FOR EXCHANGING CERTIFICATES
 
  The retention of shares of Alliance Common Stock or the conversion of shares
of Alliance Common Stock into the right to receive cash (other than shares as
to which dissenters' rights are properly exercised) pursuant to the
Recapitalization will occur at the Recapitalization Effective Time.
 
  As soon as practicable as of or after the Recapitalization Effective Time,
the Exchange Agent will send a letter of transmittal to each holder of
Alliance Common Stock (other than holders who have made a valid Retained Share
Election). The letter of transmittal will contain instructions with respect to
the surrender of certificates representing shares of Alliance Common Stock in
exchange for cash and, under certain circumstances, certificates representing
shares of Alliance Common Stock to be retained in the Recapitalization and the
amount of cash in lieu of any fractional interest in a share of Alliance
Common Stock for which the shares represented by the certificates so
surrendered are exchangeable pursuant to the Recapitalization Merger
Agreement.
 
EXCEPT FOR CERTIFICATES REPRESENTING ALLIANCE COMMON STOCK SURRENDERED WITH AN
ELECTION FORM AS DESCRIBED ABOVE UNDER "--PROCEDURE FOR RETAINED SHARE
ELECTION," ALLIANCE'S STOCKHOLDERS SHOULD NOT FORWARD STOCK CERTIFICATES TO
THE EXCHANGE AGENT UNTIL THEY HAVE RECEIVED THE LETTER OF TRANSMITTAL.
 
  As soon as practicable after the Recapitalization Effective Time, each
holder of an outstanding certificate or certificates at such time which prior
thereto represented shares of Alliance Common Stock shall, upon surrender to
the Exchange Agent of such certificate or certificates and acceptance thereof
by the Exchange Agent, be entitled to the amount of cash, if any, into which
the number of shares of Alliance Common Stock previously represented by such
certificate or certificates surrendered shall have been converted pursuant to
the Recapitalization Merger Agreement and a certificate or certificates
representing the number of full shares of Alliance Common Stock, if any, to be
retained by the holder thereof pursuant to the Recapitalization Merger
Agreement. The Exchange Agent will accept such certificates upon compliance
with such reasonable terms and conditions as the Exchange Agent may impose to
effect an orderly exchange thereof in accordance with normal exchange
practices. After the Effective Time of the Recapitalization, there will be no
further transfer on the records of Alliance or its transfer agent of
certificates representing shares of Alliance Common Stock which have been
converted, in whole or in part, pursuant to the Recapitalization Merger
Agreement, into the right to receive cash, and if such certificates are
presented to Alliance for transfer, they will be canceled against delivery of
cash and, if appropriate, certificates for retained shares of Alliance Common
Stock. Until surrendered as contemplated by the Recapitalization Merger
Agreement, each certificate for shares of Alliance Common Stock will be deemed
at any time after the Recapitalization Effective Time to represent only the
right to receive upon such surrender the consideration contemplated by the
Recapitalization Merger Agreement. No interest will be paid or will accrue on
any cash payable as consideration in the Recapitalization or in lieu of any
fractional shares of retained Alliance Common Stock.
 
  No dividends or other distributions with a record date after the
Recapitalization Effective Time will be paid with respect to any shares of
retained Alliance Common Stock represented by an unsurrendered certificate,
and no cash payment in lieu of fractional shares shall be paid to any such
holder pursuant to the Recapitalization
 
                                      52
<PAGE>
 
Merger Agreement, until the surrender of such certificate in accordance with
the Recapitalization Merger Agreement. Subject to the effect of applicable
laws, following surrender of any such certificate, there shall be paid to the
holder of the certificate representing whole shares of retained Alliance
Common Stock issued in connection therewith, without interest, (1) at the time
of such surrender or as promptly after the sale of the Excess Shares (as
defined below) as practicable, the amount of any cash payable in lieu of a
fractional share of retained Alliance Common Stock to which such holder is
entitled pursuant to the Recapitalization Merger Agreement and the
proportionate amount of dividends or other distributions, if any, with a
record date after the Effective Time of the Recapitalization theretofore paid
with respect to such whole shares of retained Alliance Common Stock, and (2)
at the appropriate payment date, the proportionate amount of dividends or
other distributions, if any, with a record date after the Recapitalization
Effective Time but prior to such surrender and a payment date subsequent to
such surrender payable with respect to such whole retained shares of Alliance
Common Stock. The Company does not intend to pay dividends on shares of
Alliance Common Stock following consummation of the Recapitalization.
 
FRACTIONAL SHARES
 
  No certificates or scrip representing fractional shares of retained Alliance
Common Stock will be issued in connection with the Recapitalization, and such
fractional share interests will not entitle the owner thereof to vote or to
any rights of a stockholder of Alliance after the Recapitalization. Each
holder of shares of Alliance Common Stock exchanged pursuant to the
Recapitalization who would otherwise have been entitled to receive a fraction
of a share of retained Alliance Common Stock (after taking into account all
shares of Alliance Common Stock delivered by such holder) will receive, in
lieu thereof, a cash payment (without interest) representing such holder's
proportionate interest in the net proceeds from the sale by the Exchange Agent
(following the deduction of applicable transaction costs), on behalf of all
such holders, of the shares (the "Excess Shares") of retained Alliance Common
Stock representing such fractions. Such sale shall be made as soon as
practicable after the Recapitalization Effective Time.
 
CONDUCT OF BUSINESS PENDING THE RECAPITALIZATION
 
  Pursuant to the Recapitalization Merger Agreement, Alliance has agreed to
carry on its business and that of its subsidiaries prior to the
Recapitalization Effective Time in the ordinary course of business consistent
with past practice. See "CERTAIN PROVISIONS OF THE RECAPITALIZATION MERGER
AGREEMENT--Conduct of Business."
 
CONDITIONS TO THE CONSUMMATION OF THE RECAPITALIZATION
 
  The Recapitalization Merger Agreement contains various conditions, including
the receipt of the necessary stockholder approval and financing, the Investor
having received advice from Ernst & Young LLP that the Recapitalization
qualifies for recapitalization accounting treatment, Alliance having taken
appropriate steps to arrange the payment or prepayment of certain capital
leases and other financing obligations, the expiration or termination of the
waiting period under the HSR Act, which waiting period has expired, the
absence of any injunction or other legal restraint or prohibition preventing
the consummation of the Merger and there not having occurred any material
adverse change in respect of Alliance. The Recapitalization Merger Agreement
also contains certain customary conditions relating to the accuracy of the
representations and warranties, the performance of the covenants and
agreements, consents having been obtained or filings having been made and
holders of less than 10% of the outstanding shares of Alliance Common Stock
having validly elected to demand appraisal of their shares. Subject to
applicable law, each of the conditions other than the condition requiring
shareholder approval, may be waived. Alliance does not intend to resolicit a
vote of its shareholders on the Recapitalization Merger Agreement in the event
any material conditions are waived, unless such waiver results in a
fundamental change in the Recapitalization, including a material change in
accounting or tax treatment, in which event Alliance has undertaken to
resolicit the vote of its shareholders and would amend this Proxy
Statement/Prospectus. However, the Investor has agreed, pursuant to the
Stockholder Agreement, not to waive any condition so as to reduce the value of
the consideration payable in the Recapitalization, materially adverse
 
                                      53
<PAGE>
 
affect the timing of the closing of the Recapitalization, reduce the Cash
Merger Price or otherwise adversely affect the interests of the Principal
Stockholders. See "CERTAIN PROVISIONS OF THE RECAPITALIZATION MERGER
AGREEMENT--Conditions" and "REGULATORY APPROVALS."
 
ANTICIPATED ACCOUNTING TREATMENT
 
  The Recapitalization will be accounted for as a recapitalization.
Accordingly, the historical basis of Alliance's assets and liabilities will
not be impacted by the transaction.
 
EFFECT ON WARRANTS AND ALLIANCE STOCK OPTIONS
 
  Pursuant to the Recapitalization Merger Agreement, as soon as practicable
following the date of the Recapitalization Merger Agreement but in no event
later than the Recapitalization Effective Time, except as described below,
Alliance (or, if appropriate, the Board of Directors of Alliance or any
committee administering the Stock Option Plans (as defined below)) will take
action, including by adopting resolutions or taking any other actions, so as
to allow each outstanding option to purchase Shares (an "Alliance Stock
Option") heretofore granted under any stock option, stock appreciation rights
or stock purchase plan, program or arrangement of Alliance (collectively, the
"Stock Option Plans") and each outstanding warrant or other right or option to
purchase Shares (a "Warrant"), in each case outstanding immediately prior to
the date hereof, whether or not then exercisable, either (i) to be canceled at
the Recapitalization Effective Time in exchange for an amount in cash, payable
at the time of such cancellation, equal to the product of (x) the number of
shares of Alliance Common Stock subject to such Alliance Stock Option or
Warrant immediately prior to the Recapitalization Effective Time and (y) the
excess of the Cash Merger Price over the per share exercise price of such
Alliance Stock Option or Warrant (the "Net Amount") or (ii) to be converted
immediately prior to the Recapitalization Effective Time into the right solely
to receive the Net Amount; provided, that no such cash payment has been made.
The Company will continue to be obligated to pay the Net Amount to holders of
any Alliance Stock Options or Warrants converted in accordance with the
foregoing.
 
  Substantially all of the stock options held by Alliance's executive officers
will become fully vested at the Recapitalization Effective Time. Pursuant to
agreements entered into as of November 10, 1997, between Alliance and certain
of its executive officers, options to purchase 70,000 shares of Alliance
Common Stock with an aggregate value of approximately $0.5 million (the
"Rollover Amount") will not be cancelled but will instead remain outstanding
following the Recapitalization Effective Time. The value of each option was
calculated by subtracting the exercise price per share of Alliance Common
Stock from the Cash Merger Price.
 
  Such options are held by management and other Alliance employees, and
substantially all of Alliance's warrants are held by certain of Alliance's
current and former institutional lenders. The total value of the options and
warrants to be paid is approximately $9.9 million and $2.1 million,
respectively. See "THE RECAPITALIZATION--Interests of Certain Persons in the
Recapitalization."
 
EFFECT ON PREFERRED STOCK
 
  The Recapitalization Merger Agreement requires Alliance to cause all of its
currently outstanding shares of preferred stock (solely comprising 3,876
shares of Series C Preferred Stock and 18,000 shares of Series D Preferred
Stock) to be redeemed or converted into shares of Alliance Common Stock on or
prior to the Special Meeting Date. All of the Series C Preferred Stock was
converted into Alliance Common Stock prior to the Record Date and,
accordingly, holders thereof may vote on the Recapitalization. The Series C
Preferred Stock was converted into 80,206 shares of Alliance Common Stock
representing 0.6% of the outstanding Alliance Common Stock (assuming
conversion of all outstanding preferred stock). The holder of the Series D
Preferred Stock has agreed that its shares of Series D Preferred Stock shall
be automatically converted into Alliance Common Stock immediately prior to the
closing of the Recapitalization. The outstanding shares of Series D Preferred
Stock are convertible into 3,000,000 shares of Alliance Common Stock,
representing approximately 21.4% of the outstanding Alliance Common Stock
(assuming conversion of all outstanding preferred stock). As
 
                                      54
<PAGE>
 
of the Record Date, the holder of the Series D Preferred Stock did not convert
its Series D Preferred Stock into Alliance Common Stock. Accordingly, such
holder will not be entitled to vote on the Recapitalization.
 
  Prior to the conversion of the Series C Preferred Stock in September 1997,
10,943,138 shares of Alliance Common Stock were outstanding; 11,023,344 shares
of Alliance Common Stock were outstanding after conversion of all Series C
Preferred Stock. The conversion of the Series D Preferred Stock will increase
the number of outstanding shares of Alliance Common Stock to 14,023,344,
assuming no additional issuance of Alliance Common Stock from the exercise of
outstanding stock options.
 
  In connection with the Recapitalization, Apollo will purchase $15 million of
a new issue of Alliance's Series F Preferred Stock. Alliance decided to issue
the Series F Preferred Stock in connection with the Recapitalization because
additional equity financing was required in order for Alliance to consummate
the Recapitalization. The terms of the Series F Preferred Stock were
determined through negotiations between Alliance and Apollo. See "--Background
of the Recapitalization" and "DESCRIPTION OF ALLIANCE CAPITAL STOCK--Series F
Preferred Stock."
 
 
POSSIBLE DELISTING; TERMINATION OF SEC REPORTING
 
  Following the consummation of the Recapitalization, Alliance may be required
to or may seek to have the Alliance Common Stock, which is currently traded on
the Nasdaq SmallCap Market, delisted and may deregister under the Exchange
Act. See "RISK FACTORS--Possible Delisting; Loss of Liquidity" and "RISK
FACTORS--Termination of SEC Reporting."
 
RESALE OF ALLIANCE COMMON STOCK FOLLOWING THE RECAPITALIZATION
 
  Alliance Common Stock to be retained in connection with the Recapitalization
will be freely transferable, except that shares retained by any stockholder
who is an "affiliate" (as defined under the Securities Act and generally
including, without limitation, directors, certain executive officers and
beneficial owners of 10% or more of a class of capital stock) of Alliance for
purposes of Rule 145 under the Securities Act will not be transferable except
pursuant to an effective registration statement or an exemption from the
registration requirements of the Securities Act. This Proxy
Statement/Prospectus does not cover sales of Alliance Common Stock retained by
any person who is an affiliate of Alliance.
 
CONVERSION OF NEWCO STOCK
 
  By virtue of the Recapitalization, the shares of common stock, par value
$.01, of Newco that are issued and outstanding immediately prior to the
Recapitalization Effective Time will be converted into and become 3,632,222
shares of Alliance Common Stock.
 
CERTAIN TAX CONSEQUENCES OF THE RECAPITALIZATION
 
  This discussion contains a summary of the opinion of Irell & Manella LLP,
counsel to Alliance ("Counsel"), as to the material United States federal
income tax ("U.S. federal income tax") consequences of the Recapitalization.
Such opinion is not binding upon the Internal Revenue Service (the "Service")
and no assurance can be given that the Service will not take contrary
positions. If the Service were to assert positions contrary to the U.S.
federal income tax consequences described herein and in the opinion, the
consequences so described, if properly presented to a court, should prevail.
However, there is a risk that such contrary positions of the Service might
ultimately be sustained by the courts. The opinion of Counsel is not binding
on the courts, and should not be construed as a guarantee of ultimate results.
This discussion does not purport to be a complete analysis or discussion of
all potential tax considerations or consequences relevant to a decision
whether to vote for the approval of the Recapitalization. The discussion does
not address all aspects of U.S. federal income taxation that may be applicable
to Alliance stockholders in light of their status or personal investment
circumstances including, without limitation, the alternative minimum tax. In
particular, it does not address the
 
                                      55
<PAGE>
 
U.S. federal income tax consequences of the Recapitalization that are
applicable to Alliance's stockholders subject to special U.S. federal income
tax treatment including (without limitation) persons who are not U.S. citizens
or residents, foreign persons, insurance companies, tax-exempt entities,
retirement plans, dealers in securities, persons who acquired their Alliance
Common Stock pursuant to the exercise of employee stock options or otherwise
as compensation and persons who hold their Alliance Common Stock as part of a
"straddle," "hedge" or "conversion transaction."
 
  The discussion addresses neither the effect of any applicable state, local
or foreign tax laws, nor the effect of any federal tax laws other than those
pertaining to the U.S. federal income tax. THE FOLLOWING CONTAINS A SUMMARY OF
THE OPINION OF COUNSEL AS TO THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES
OF THE RECAPITALIZATION TO CERTAIN OF ALLIANCE'S STOCKHOLDERS. THE FOLLOWING
DISCUSSION DOES NOT TAKE INTO ACCOUNT THE PARTICULAR FACTS AND CIRCUMSTANCES
OF EACH STOCKHOLDER'S TAX STATUS AND ATTRIBUTES. AS A RESULT, THE U.S. FEDERAL
INCOME TAX CONSEQUENCES ADDRESSED IN THE FOLLOWING MAY NOT APPLY TO EACH OF
ALLIANCE'S STOCKHOLDERS. ACCORDINGLY, EACH STOCKHOLDER SHOULD CONSULT ITS OWN
TAX ADVISORS REGARDING THE SPECIFIC TAX CONSEQUENCES OF THE RECAPITALIZATION,
INCLUDING THE APPLICATION AND EFFECT OF FEDERAL, STATE, LOCAL AND FOREIGN TAX
LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL AND OTHER TAX LAWS.
 
  The discussion is based on the Code, the regulations proposed or promulgated
thereunder and current administrative interpretations and judicial precedents
relating thereto, all of which are subject to change. Any such change, which
may or may not be retroactive, could alter the tax consequences discussed
herein. The discussion is also based on certain customary assumptions
regarding the factual circumstances that will exist at the Recapitalization
Effective Time. If any of these factual assumptions is inaccurate, the tax
consequences of the Recapitalization could differ from those described herein.
The discussion assumes that shares of Alliance Common Stock are held as
capital assets (within the meaning of Section 1221 of the Code) at the
Recapitalization Effective Time.
 
  Characterization of the Recapitalization for U.S. Federal Income Tax
Purposes. Subject to the assumptions, limitations and qualifications set forth
elsewhere in "--Certain Tax Consequences of the Recapitalization," Counsel is
of the opinion that for U.S. federal income tax purposes, Newco will be
disregarded as a transitory entity, and the merger of Newco with and into
Alliance will be treated as a sale of a portion of a stockholder's Alliance
Common Stock to the Investor in connection with the Recapitalization and as a
redemption of a portion of such stockholder's Alliance Common Stock by
Alliance. The number of shares of Alliance Common Stock disposed of by a
stockholder pursuant to the Recapitalization that will be treated as sold in
the Recapitalization will be equal to the total number of shares surrendered
by the stockholder multiplied by (a) the amount of cash contributed to Newco
by the Investor in exchange for Newco stock (or otherwise) prior to the
Recapitalization Effective Time (and not attributable to expenses) divided by
(b) the aggregate amount of cash paid to stockholders pursuant to the
Recapitalization. The remainder of the stockholder's shares of Alliance Common
Stock disposed of in the Recapitalization will be treated as redeemed by
Alliance. Because the Actual Retained Share Number is limited to 411,358
shares of Alliance Common Stock and stockholders making a Retained Share
Election will be subject to pro rata reduction in the event the number of
shares of Alliance Stock for which elections to retain such shares are validly
made exceeds the Actual Retained Share Number, there can be no assurance that
a stockholder making an election will be able to retain all of its shares of
Alliance Common Stock. See "--Stockholders Receiving Cash" below for a
discussion of the consequences of cash being deemed paid in redemption of
Alliance Common Stock.
 
  Stockholders Receiving Cash. Subject to the assumptions, limitations and
qualifications set forth elsewhere in "--Certain Tax Consequences of the
Recapitalization," Counsel is of the opinion that the material U.S. federal
income tax consequences of the Recapitalization with respect to a particular
stockholder who receives cash (including cash paid to dissenters and cash in
lieu of fractional shares) are as set forth herein. As described more fully
below, the U.S. federal income tax consequences of the Recapitalization with
respect to a particular
 
                                      56
<PAGE>
 
stockholder who receives cash (including cash paid to dissenters and cash paid
in lieu of fractional shares) will depend upon, among other things, (i) the
extent to which a stockholder is deemed to have sold its Alliance Common Stock
in the Recapitalization or is deemed to have had its shares of Alliance Stock
redeemed by Alliance and (ii) whether the deemed redemption of a holder's
Alliance Common Stock by Alliance will qualify as a sale or exchange under
Section 302 of the Code. First, to the extent that a stockholder is considered
to have sold Alliance Common Stock in the Recapitalization, such stockholder
will recognize either capital gain or loss in an amount equal to the
difference between (x) the number of shares treated as sold in the
Recapitalization multiplied by $11.00 and (y) the stockholder's adjusted tax
basis in such shares. Such gain or loss generally will be mid-term capital
gain or loss, currently taxable at a maximum rate of 28% (for individuals), in
respect of Alliance Common Stock held by the stockholder for more than one
year and long-term capital gain or loss, currently taxable at a maximum rate
of 20% (for individuals; which rate may be 10% for individuals in lower tax
brackets), in respect of Alliance Common Stock held by the stockholder for
more than 18 months. Second, a stockholder also will recognize either capital
gain or loss equal to the difference between (x) the number of shares treated
as redeemed by Alliance multiplied by $11.00 and (y) the stockholder's
adjusted tax basis in such Common Stock, if such redemption is treated as a
sale or exchange under Section 302 of the Code with respect to such
stockholder. Such gain or loss will also generally be mid-term or long-term
capital gain or loss in respect of Alliance Common Stock held by an individual
stockholder for more than one year or 18 months, respectively.
 
  Under Section 302 of the Code, a redemption of Alliance Common Stock
pursuant to the Recapitalization will, as a general rule, be treated as a sale
or exchange if the redemption (a) results in a "complete termination" of the
stockholder's interest in Alliance, (b) is "substantially disproportionate"
with respect to the stockholder or (c) is "not essentially equivalent to a
dividend" with respect to the stockholder. In determining whether any of these
Section 302 tests is satisfied, stockholders must take into account not only
Alliance Common Stock that they actually own, but also any Alliance Common
Stock they are "deemed" to own under the constructive ownership rules set
forth in Section 318 of the Code. Pursuant to these constructive ownership
rules, a stockholder will be deemed to own stock that is actually or
constructively owned by certain members of his or her family (spouse,
children, grandchildren and parents) and other related parties including, for
example, certain entities in which such stockholder has a direct or indirect
interest (including partnerships, estates, trusts and corporations), as well
as shares of stock that such stockholder (or a related person) has the right
to acquire upon exercise of an option or conversion right. In addition, if a
stockholder lives in a community property state, the community property laws
of that state may have an effect on the constructive ownership rules.
Stockholders who live in a community property state should consult their own
advisors with respect to the impact of community property laws on the
constructive ownership rules. Section 302(c)(2) of the Code provides certain
exceptions to the family attribution rules for the purpose of determining a
"complete termination." If a stockholder intends to rely upon these
exceptions, the stockholder must file a "waiver of family attribution"
statement with his tax return and must comply with certain other requirements
set forth in the Code and Regulations.
 
  The redemption of a stockholder's shares of Alliance Common Stock will
result in a "complete termination" of a stockholder's interest in Alliance if
either (a) all Alliance Common Stock actually and constructively owned by the
stockholder is redeemed or sold pursuant to the Recapitalization or (b) all of
the Alliance Common Stock actually owned by the stockholder is redeemed or
sold pursuant to the Recapitalization and the stockholder is eligible to
waive, and does effectively waive in accordance with Section 302(c) of the
Code, attribution of all Alliance Common Stock which otherwise would be
considered to be constructively owned by such stockholder. Such waiver of
attribution applies only to Alliance Common Stock that would be attributed to
a stockholder from members of such stockholder's family. Stockholders should
consult their own tax advisors with respect to the application of the
"complete termination" test to their particular facts and circumstances.
 
  The redemption of a stockholder's Alliance Common Stock will be
"substantially disproportionate" with respect to such stockholder if the
percentage of Alliance Common Stock actually and constructively owned by such
stockholder immediately following the Recapitalization is less than 80% of the
percentage of Alliance Common Stock actually and constructively owned by such
stockholder immediately prior to the Recapitalization and is less than 50% of
the total Alliance Common Stock outstanding after the Recapitalization.
Stockholders
 
                                      57
<PAGE>
 
should consult their own tax advisors with respect to the application of the
"substantially disproportionate" test to their particular facts and
circumstances. Waiver of family attribution is not available in applying the
"substantially disproportionate" test.
 
  Even if the redemption of a stockholder's Alliance Common Stock fails to
satisfy the "complete termination" test and the "substantially
disproportionate" test described above, the redemption of a stockholder's
Alliance Common Stock may nevertheless satisfy the "not essentially equivalent
to a dividend" test if the stockholder's redemption of Alliance Common Stock
pursuant to the Recapitalization results in a "meaningful reduction" in such
stockholder's proportionate Alliance Common Stock interest in Alliance.
Whether the receipt of cash by a stockholder will be considered "not
essentially equivalent to a dividend" will depend upon such stockholder's
particular facts and circumstances. No general guidelines indicating the facts
and circumstances under which a redemption will be considered to produce a
meaningful reduction in proportionate interest have been provided by the
courts or issued by the Service. However, the Service has clearly stated its
position that if no reduction in percentage interest occurs, none of the
Section 302 tests will be satisfied. Stockholders should consult with their
own tax advisors as to the application of this test in their particular
situation. Waiver of family attribution is not available in the context of the
"not essentially equivalent to a dividend" test.
 
  In assessing whether the redemption of a stockholder's shares of Alliance
Common Stock satisfies the "substantially disproportionate" test or the "not
essentially equivalent to a dividend" test described above, stockholders
should consider the fact that the Recapitalization will substantially reduce
the number of outstanding shares of Alliance Common Stock. As a result, if a
stockholder elects to retain a portion of its Alliance Common Stock, the
stockholder's percentage interest in Alliance Common Stock of Alliance may not
be reduced even if the stockholder receives cash for a substantial portion of
its Alliance Common Stock. Stockholders should consult their own tax advisors
as to the impact of the reduction in the outstanding shares of Alliance Common
Stock on the application of the "substantially disproportionate" and "not
essentially equivalent to a dividend" tests described above.
 
  With respect to shares of Alliance Common Stock treated as redeemed, if a
stockholder cannot satisfy any of the three tests described above and to the
extent Alliance has sufficient current and/or accumulated earnings and
profits, such stockholder will be treated as having received a dividend which
will be includible in gross income (and treated as ordinary income) in an
amount equal to that portion of the cash received with respect to the deemed
redemption of the Alliance Common Stock. In addition, the stockholder's basis
in such Alliance Common Stock disposed of will not offset the amount of cash
received, but instead will be reallocated to shares of Alliance Common Stock
still held by such stockholder or, although the matter is not free from doubt,
if no shares are actually owned, reallocated to those shares constructively
owned, under certain circumstances. To the extent that a portion of the cash
received with respect to the deemed redemption of the shares of Alliance
Common Stock exceeds the current and/or accumulated earnings and profits of
Alliance attributable to the retained and (deemed) redeemed shares of Alliance
Common Stock, such excess will first be treated as a non-taxable return of
capital to the extent of the basis attributable to such retained and (deemed)
redeemed shares and then as a capital gain. Such capital gain will be short-
term, mid-term or long-term depending on the holding period for the retained
shares. If a stockholder acquired shares of Alliance Common Stock at different
times and/or at different prices, the application of the rules for basis
reduction, gain recognition and type of capital gain is unclear. Stockholders
in such situation should consult their tax advisors to determine an
appropriate methodology for determining the amounts of basis reduction and
gain recognition and type of capital gain, if any, recognized.
 
  To the extent that one of the three tests described above is satisfied, a
stockholder will be treated as having sold its Alliance Common Stock, which
will generally give rise to mid-term or long-term capital gain or loss in
respect of Alliance Common Stock held by the individual stockholder for more
than 12 or 18 months, respectively. While the marginal tax rates for dividends
and capital gains are the same for corporate stockholders, the current maximum
U.S. federal income tax rate on ordinary income and short-term capital gains
of individuals (39.6%) exceeds the maximum tax rate on mid-term capital gains
(28%) and on long-term capital gains (20%).
 
                                      58
<PAGE>
 
In addition, capital gain can generally be offset by any capital loss that an
individual stockholder may have incurred, whereas capital loss of a
corporation may not offset ordinary income, and capital loss of an individual
can only offset ordinary income to the extent of $3,000 per year (subject to
carryover).
 
  In the case of a corporate stockholder, if the cash paid is treated as a
dividend, such dividend income may be eligible for the 70% (or 80% if more
than 20% of the vote and value of Alliance Common Stock is held by such
corporate stockholder) dividends-received deduction. The dividends-received
deduction is subject to certain limitations, and may not be available if the
corporate stockholder does not satisfy certain holding period requirements
with respect to Alliance Common Stock or if Alliance Common Stock is treated
as "debt financed portfolio Stock" within the meaning of Code Section 246A(c).
Additionally, if a dividends-received deduction is available, the dividend may
be treated as an "extraordinary dividend" under Section 1059(a) of the Code,
in which case a corporate stockholder's adjusted tax basis in Alliance Common
Stock retained by such stockholder would be reduced, but not below zero, by
the amount of the nontaxed portion of such dividend. Any amount of the
nontaxed portion of the dividend in excess of the corporate stockholder's
adjusted tax basis generally will be subject to taxation when the
extraordinary dividend is received. Corporate stockholders are urged to
consult their own tax advisors as to the effect of Section 1059 of the Code.
 
  BECAUSE THE DETERMINATION OF WHETHER THE RECEIPT OF CASH WILL BE TREATED AS
HAVING THE EFFECT OF THE DISTRIBUTION OF A DIVIDEND WILL GENERALLY DEPEND UPON
THE FACTS AND CIRCUMSTANCES OF EACH ALLIANCE STOCKHOLDER, ALLIANCE'S
STOCKHOLDERS ARE STRONGLY ADVISED TO CONSULT THEIR OWN TAX ADVISORS REGARDING
THE TAX TREATMENT OF CASH RECEIVED IN THE RECAPITALIZATION.
 
  The ability to elect the type of consideration to be received pursuant to
the Recapitalization affords each stockholder some flexibility in selecting
the type of consideration that will best serve his or her personal tax and
financial planning needs. However, each stockholder should be aware that his
or her ability to satisfy (or, alternatively, fail to satisfy) any of the
foregoing tests and thereby avoid (or, alternatively, obtain) dividend
treatment may be affected by the various adjustments, pro-rations and
allocations of the Recapitalization consideration. Stockholders may receive
more or less cash than may be anticipated at the time an election to receive
cash or retain shares is made.
 
  Stockholders Retaining Alliance Common Stock and Receiving No Cash. Subject
to the assumptions, limitations and qualifications set forth elsewhere in "--
Certain Tax Consequences of the Recapitalization," Counsel is of the opinion
that the Recapitalization will have no U.S. federal income tax consequences
for stockholders who retain their Alliance Common Stock and receive no cash.
Accordingly, a stockholder will not recognize any gain or loss on any Alliance
Common Stock retained by such stockholder.
 
  Stockholders Retaining a Portion of their Alliance Common Stock and
Receiving Cash. Subject to the assumptions, limitations and qualifications set
forth elsewhere in "--Certain Tax Consequences of the Recapitalization,"
Counsel is of the opinion that to the extent that a stockholder elects to
retain a portion of its Alliance Common Stock and exchange a portion of its
Alliance Common Stock for cash and does receive cash, or to the extent a
stockholder receives cash in exchange for some portion of its Alliance Common
Stock as a result of proration, the tax treatment of the stockholder's receipt
of such cash will be the same as set forth above under "--Stockholders
Receiving Cash."
 
  Information Reporting and Backup Withholding. Alliance must report annually
to the Service and to each stockholder the amount of dividends paid to such
stockholder and the backup withholding tax, if any, withheld with respect to
such dividends. Backup withholding is a withholding tax imposed at the rate of
31% on certain payments to persons that fail to furnish certain information
under the United States information reporting requirements. Payment of the
proceeds of a sale of Alliance Common Stock by or through a United States
office of a broker is subject to both backup withholding and information
reporting unless the beneficial owner establishes an exemption. Any amounts
withheld under the backup withholding rules may be allowed as a refund or a
credit against the holder's U.S. federal income tax liability provided the
required information is furnished to the Service.

          CERTAIN PROVISIONS OF THE RECAPITALIZATION MERGER AGREEMENT
 
  The following is a brief summary of the Recapitalization Merger Agreement,
as amended, a copy of which appears as Annex A to this Proxy
Statement/Prospectus and is incorporated herein by reference. Such summary is
qualified in its entirety by reference to the Recapitalization Merger
Agreement, as amended.
 
  Pursuant to the Recapitalization Merger Agreement, if the Recapitalization
Merger Agreement is approved by the holders of a majority of Alliance's Common
Stock eligible to vote at the Special Meeting and the other conditions to the
Recapitalization are satisfied or waived, at the Recapitalization Effective
Time, the separate corporate existence of Newco will cease, the Company will
continue as the surviving corporation and each share of Alliance Common Stock
issued and outstanding immediately prior to the Recapitalization Effective
Time, other than shares of Alliance Common Stock held by stockholders of
Alliance, if any, who dissent from the Recapitalization and comply with all of
the provisions of the DGCL concerning the right of holders of shares of
Alliance Common Stock to seek appraisal of their shares of Alliance Common
Stock, either (1) will be converted into the right to receive $11.00 in cash
or (2) will be retained by such stockholder. See "THE RECAPITALIZATION."
 
  Termination of the Recapitalization Merger Agreement. The Recapitalization
Merger Agreement provides that it may be terminated at any time prior to the
Recapitalization Effective Time, whether before or after approval of the terms
of the Recapitalization Merger Agreement by the stockholders of Alliance, as
follows:
 
    (a) by mutual written consent of the Investor and Alliance; (b) by either
  the Investor or Alliance if the Recapitalization Effective Time shall not
  have occurred on or before December 31, 1997 (provided that the right to
  terminate the Recapitalization Merger Agreement under this clause (b) shall
  not be available to any party whose failure to fulfill any obligation under
  the Recapitalization Merger Agreement has been the cause of or resulted in
  the failure of the Recapitalization Effective Time to occur on or before
  such date); (c) by either the Investor or Alliance if any governmental
  entity shall have issued an order, decree or ruling or taken any other
  action permanently enjoining, restraining or otherwise prohibiting the
  Recapitalization and such order, decree or ruling or other action shall
  have become final and nonappealable; (d) by either the Investor or Alliance
  if the approval of the Recapitalization Merger Agreement and the
  Recapitalization by Alliance's stockholders is not obtained by reason of
  the failure to obtain the required vote upon a vote held at a duly called
  meeting of stockholders or at any adjournment thereof; (e) by the Investor,
  if (x) any of the representations and warranties of Alliance contained in
  the Recapitalization Merger Agreement shall fail to be true and correct in
  any material respect, in each case either when made or (except for
  representations and warranties made only as of a specific date) have since
  become, and at the time of termination remain, untrue in any material
  respect, or (y) Alliance shall have breached or failed to comply in any
  material respect with any of its obligations under the Recapitalization
  Merger Agreement (other than as a result of a breach by the Investor or
  Newco of any of their obligations under the Recapitalization Merger
  Agreement) and such breach or failure shall continue unremedied for ten
  (10) days after Alliance has received written notice from the Investor or
  the Newco of the occurrence of such breach or failure; provided, however,
  that in remedying any such breach or failure Alliance shall not have spent
  any money, incurred any liabilities or undertaken any obligations that,
  individually or together with the breach or failure so remedied, would
  itself constitute a breach of or failure to perform any representation,
  warranty or covenant of the Recapitalization Merger Agreement; (f) by the
  Investor if there shall have occurred any change or event that,
  individually or in the aggregate, with any other change or event, is
  materially adverse to the assets, properties, business, financial
  condition, results of operations or prospects of Alliance, taken as a
  whole; (g) by either the Investor or Alliance if, prior to the
  Recapitalization Effective Time, (i) the Board of Directors determines that
  a Third Party Proposal (as defined below) for an Alternative Transaction
  (as defined below) constitutes a Superior Proposal (as defined below), (ii)
  Alliance promptly notifies the Investor of its determination in writing,
  which writing shall set forth the terms and conditions of the Third Party
  Proposal and the identity of the person making the Third Party Proposal,
  (iii) ten days have elapsed following receipt by the Investor of such
  written notice, (iv) during such ten day period Alliance cooperates with
  the Investor with the intent of enabling, but not obligating, the Investor
  and Alliance to agree to a modification of the terms and conditions of the
  Recapitalization Merger Agreement so that the transactions contemplated
  thereby may be effected and (v) at the end of such ten day period, the
  Board of Directors continues to believe that such Third Party
 
                                      60
<PAGE>
 
  Proposal constitutes a Superior Proposal and Alliance pays to the Investor
  the amount specified under the section below entitled "Fees and Expenses"
  or (h) by Alliance if (i) any of the representations and warranties of the
  Investor or Newco contained in the Recapitalization Merger Agreement shall
  fail to be true and correct in any material respect, in each case either
  when made or (except for representations and warranties made only as of a
  specific date) have since become, and at the time of termination remain,
  untrue in any material respect, or (ii) the Investor or the Newco shall
  have breached or failed to comply in any material respect with any of its
  obligations under the Recapitalization Merger Agreement (other than as a
  result of a breach by Alliance of any of its obligations under the
  Recapitalization Merger Agreement) and such breach or failure shall
  continue unremedied for ten (10) days after the Investor or the Newco has
  received written notice from Alliance of the occurrence of such breach or
  failure; provided, however, that in remedying any such breach or failure
  neither the Investor nor Newco shall have spent any money, incurred any
  liabilities or undertaken any obligations that, individually or together
  with the breach or failure so remedied, would itself constitute a breach of
  or failure to perform any representation, warranty or covenant of the
  Recapitalization Merger Agreement.
 
  For purposes of the Recapitalization Merger Agreement, a "Superior Proposal"
means any Third Party Proposal to acquire, directly or indirectly, at least
80% of the shares of Alliance Common Stock or all or substantially all of the
assets of Alliance; provided that (i) the Board of Directors of Alliance
determines in its good faith judgment (following consultation with and the
receipt of the advice of Alliance's financial advisor) that such Third Party
Proposal is on terms that are more favorable to Alliance's stockholders than
the Recapitalization (taking into account all factors that the Board of
Directors reasonably deems relevant, including, in the judgment of the Board
of Directors, the amount and form of consideration to be received in respect
of shares of Alliance Common Stock, and the timing of, and likelihood of
closing such proposal and the relative value of any non-cash consideration)
and (ii) the Board of Directors of Alliance determines in its good faith
judgment (following receipt of the written advice of its outside counsel) that
the failure to recommend or accept such Third Party Proposal would violate the
fiduciary duties of the Board of Directors of Alliance to its stockholders
under applicable law.
 
  Alternative Transactions. The Recapitalization Merger Agreement provides
that Alliance shall, shall cause each Subsidiary to and shall direct and use
reasonable efforts to cause its and its Subsidiaries' officers, directors,
employees, representatives and agents to, immediately cease any discussions or
negotiations with any parties other than Investor and Newco that may be
ongoing with respect to an Alternative Transaction (as defined below). The
Recapitalization Merger Agreement further provides that Alliance shall not,
shall cause each of its Subsidiaries not to and shall not authorize and shall
direct and use reasonable efforts to cause its and its Subsidiaries' officers,
directors, employees and any investment banker, financial advisor, attorney,
accountant or other representative retained by it not to, directly or
indirectly, (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 may lead to an Alternative Transaction or (ii)
participate in any discussions or negotiations regarding any proposed
Alternative Transaction; provided, however, that if, during the 45 days
following the date of the Recapitalization Merger Agreement, the Board of
Directors determines in good faith, after consultation with its financial
advisors, and following receipt of written advice from outside counsel, that
action is required by reason of Alliance's Board of Directors' fiduciary
duties to Alliance's stockholders under applicable law, Alliance may (subject
to compliance with Alliance's notification obligations discussed below),
during such 45 day period, in response to an unsolicited Third Party Proposal
(as defined below), (A) furnish information with respect to Alliance to the
person making such Third Party Proposal pursuant to a confidentiality
agreement that is at least as protective of Alliance's interests as is the
Confidentiality Agreement (as defined below), (B) participate in negotiations
regarding such Third Party Proposal and (C) take any position (and disclose
such position to its stockholders) with regard to such Third Party Proposal
pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange Act;
provided, however, that in the case of clause (C), (x) Alliance shall have
provided the Investor and Newco with as much advance notice of its position
and proposed disclosure as is practicable under the circumstances and (y)
neither Alliance nor its Board of Directors nor any committee thereof shall,
except as permitted below, withdraw or modify its position with respect to the
Recapitalization or the Recapitalization Merger Agreement or approve or
recommend such Third Party Proposal.
 
                                      61
<PAGE>
 
  For purposes of the Recapitalization Merger Agreement, a "Third Party
Proposal" means a bona fide proposal from a third party, which proposal did
not result from a breach of the foregoing by Alliance and which third party
the Board of Directors of Alliance determines in good faith, taking into
account all factors that the Board of Directors reasonably deems relevant and
upon the advice of Alliance's financial advisor, has the capacity and is
reasonably likely to have the ability to consummate a Superior Proposal. For
purposes of the Recapitalization Merger Agreement, an "Alternative
Transaction" means any direct or indirect acquisition or purchase of assets of
Alliance or any subsidiary thereof outside the ordinary course of business or
any outstanding equity securities of Alliance or any subsidiary thereof, any
tender offer or exchange offer that if consummated would result in any person
beneficially owning equity securities of Alliance or any merger,
consolidation, business combination, sale of substantially all the assets,
recapitalization, liquidation, dissolution or similar transaction involving
Alliance, other than the transactions contemplated by the Recapitalization
Merger Agreement and other than the acquisition of shares of Alliance Common
Stock pursuant to the exercise of Alliance Stock Options or Warrants that are
issued and outstanding as of July 23, 1997 or the conversion of Alliance's
Series C preferred stock (the "Alliance Series C Shares") or Alliance's Series
D preferred stock (the "Alliance Series D Shares").
 
  Neither the Board of Directors nor any committee thereof shall (i) withdraw
or modify the approval or recommendation by such Board of Directors or such
committee of the Recapitalization Merger Agreement or the Recapitalization,
(ii) approve or recommend any Alternative Transaction or (iii) cause Alliance
to enter into any letter of intent, agreement in principle, acquisition
agreement or other agreement, including any exclusivity agreement (an
"Acquisition Agreement"), with respect to an Alternative Transaction unless
the Board of Directors of Alliance shall have previously terminated the
Recapitalization Merger Agreement pursuant to clause (g) under the Section
above entitled "Termination of the Recapitalization Merger Agreement."
 
  In addition to the obligations of Alliance set forth above, the
Recapitalization Merger Agreement requires Alliance (i) to immediately advise
the Investor orally and in writing of any request for information or of any
proposal or any inquiry regarding any Alternative Transaction, the material
terms and conditions of such request, proposal or inquiry and the identity of
the person making such request, proposal or inquiry and (ii) to keep the
Investor fully informed of the status and details (including amendments or
proposed amendments) of any such request, proposal or inquiry.
 
  Fees and Expenses. The Recapitalization Merger Agreement provides, in
general, that all fees and expenses incurred in connection with the
Recapitalization, the Recapitalization Merger Agreement and the transactions
contemplated by the Recapitalization Merger Agreement shall be paid by the
party incurring such fees or expenses, whether or not the Recapitalization is
consummated. However, certain termination fees and expenses are payable under
the Recapitalization Merger Agreement, as follows:
 
    (a) If the Recapitalization Merger Agreement is terminated (i) pursuant
  to clause (g) under the section above entitled "Termination of the
  Recapitalization Merger Agreement," (ii) by the Investor pursuant to clause
  (b) or clause (e) under the section above entitled "Termination of the
  Recapitalization Merger Agreement" as a result of any willful breach by
  Alliance of any covenant or agreement made in the Recapitalization Merger
  Agreement or (iii) by the Investor pursuant to clause (b) or clause (e)
  under the section above entitled "Termination of the Recapitalization
  Merger Agreement" as a result of any failure or failures to be true as of
  the date thereof of one or more of the representations and warranties made
  by Alliance in the Recapitalization Merger Agreement, which failures to be
  true are reasonably expected to have an aggregate negative impact on the
  value of Alliance and its subsidiaries, taken as a whole (a "Negative
  Impact"), of $25 million or more, Alliance shall pay to the Investor within
  90 days of such termination (except for any termination pursuant to clause
  (g), in which case payment shall be made promptly upon such termination),
  $10 million (or, in the case of clause (iii), $5 million) plus all Expenses
  (as defined below).
 
    (b) If the Recapitalization Merger Agreement is terminated (i) by the
  Investor pursuant to clause (b) or clause (e) under the section above
  entitled "Termination of the Recapitalization Merger Agreement" as a result
  of any breach by Alliance, other than a willful breach, of any covenant or
  agreement made in the Recapitalization Merger Agreement, (ii) by the
  Investor pursuant to clause (b) or clause (e) under the section
 
                                      62
<PAGE>
 
  above entitled "Termination of the Recapitalization Merger Agreement" as a
  result of any failure or failures to be true as of the date of the
  Recapitalization Merger Agreement of one or more representations and
  warranties made by Alliance in the Recapitalization Merger Agreement which
  failures to be true in the aggregate have a Negative Impact of less than
  $25 million, (iii) by the Investor pursuant to clause (b) or clause (e)
  under the section above entitled "Termination of the Recapitalization
  Merger Agreement" as a result of any failure or failures to be true as of
  the time of such termination one or more representations and warranties,
  which representations and warranties were true as of the date of the
  Recapitalization Merger Agreement, (iv) by the Investor pursuant to clause
  (b) under the section above entitled "Termination of the Recapitalization
  Merger Agreement" as a result of a failure to satisfy the condition to the
  Investor's and Newco's obligations of no material adverse change having
  occurred or (v) pursuant to clause (f) under the section above entitled
  "Termination of the Recapitalization Merger Agreement," Alliance shall
  promptly pay to the Investor all Expenses (as defined below), and, if,
  within 180 days of such termination either an Alternative Transaction shall
  be consummated or Alliance shall enter into an Acquisition Agreement
  providing for an Alternative Transaction (in either event, the "Tail
  Condition"), then Alliance shall pay to the Investor, upon the closing of
  such transaction, if and whenever it occurs, $5 million.
 
    (c) If the Recapitalization Merger Agreement is terminated by the
  Investor pursuant to clause (b) under the section above entitled
  "Termination of the Recapitalization Merger Agreement" as a result of a
  failure to obtain the approval of the Recapitalization Merger Agreement and
  the Recapitalization or pursuant to clause (d) under the section above
  entitled "Termination of the Recapitalization Merger Agreement," Alliance
  shall pay to the Investor all Expenses, and if the Tail Condition is
  subsequently satisfied, shall pay to the Investor upon the closing of the
  relevant transaction, if and whenever it occurs, $10 million; provided,
  however that no amounts whatsoever shall be payable to the Investor under
  this clause (c) if, at the Special Meeting or any adjournments or
  postponements thereof, the Investor fails to vote or cause to be voted, or
  fails to grant or to cause the granting of consent or approval with respect
  to, any shares of Alliance Common Stock owned by Alliance or any Affiliate
  thereof or as to which it or any Affiliate thereof has voting rights in
  favor of the Recapitalization Merger and the adoption by Alliance of the
  Recapitalization Merger Agreement and Recapitalization.
 
    (d) If the Recapitalization Merger Agreement is terminated (i) by the
  Investor pursuant to clause (b) under the section above entitled
  "Termination of the Recapitalization Merger Agreement" in connection with
  the failure of any of the conditions set forth in any of the following:
  clause (b), (c) or (d) under the conditions to each party's obligations to
  effect the Recapitalization as set forth below in the section entitled
  "Conditions" or clause (b), (d), (e), (f), (g), (h) or (i) under the
  conditions to the Investor's and Newco's obligations to effect the
  Recapitalization as set forth below in the section entitled "Conditions"
  and the Tail Condition is subsequently satisfied or (ii) by the Investor
  pursuant to clause (c) under the section above entitled "Termination of the
  Recapitalization Merger Agreement" and the Tail Condition is subsequently
  satisfied, Alliance shall pay to the Investor, upon the closing of the
  relevant transaction, if and wherever it occurs, $5 million plus Expenses.
 
  For purposes of the Recapitalization Merger Agreement, "Expenses" means all
reasonably documented out-of-pocket expenses incurred by the Investor and
Newco in connection with the Recapitalization Merger Agreement (including the
financing contemplated thereby), the Stockholder Agreement and the
transactions contemplated by the Recapitalization Merger Agreement and
thereby, including fees and expenses of its, and its financing sources',
printer, consultants, attorneys, accountants, and other advisors; provided,
however, that (i) such expenses shall not include any advisory or similar fees
paid to the Investor or any Affiliate thereof or to any investment banking
firm or placement agent retained in connection with the financing contemplated
by the Recapitalization Merger Agreement and (ii) unless Alliance has
previously agreed in writing to increase such amount, the aggregate amount of
such Expenses shall not exceed (i) $3 million if such termination occurs prior
to September 1, 1997, or (ii) $5 million if such termination occurs thereafter
(the parties further agreeing that such amounts shall be reduced, dollar for
dollar, to the extent that Alliance funds the expenses (excluding for the
services of Alliance's professionals) of filing or printing this Proxy
Statement/Prospectus or the solicitation of proxies with respect thereto).
 
 
                                      63

  Conditions. The Recapitalization Merger Agreement provides that the
respective obligations of each party to effect the Recapitalization are
subject to the satisfaction or waiver, where permissible, prior to the
Recapitalization Effective Time, of the following conditions:
 
    (a) Alliance's stockholders shall have approved the Recapitalization
  Merger Agreement and the Recapitalization as required by and in accordance
  with applicable law and Alliance's Second Restated Certificate of
  Incorporation.
 
    (b) No statute, rule, regulation, executive order, decree or injunction
  shall have been enacted, entered, promulgated or enforced by any court or
  governmental entity that prohibits or restricts the consummation of the
  Recapitalization or makes such consummation illegal (each party agreeing to
  use commercially reasonable efforts to have any such prohibition lifted).
 
    (c) The waiting period applicable to the consummation of the
  Recapitalization under the HSR Act shall have expired or been terminated.
 
    (d) The Registration Statement on Form S-4 (or an alternative form
  prescribed by the Commission) shall have been declared effective and shall
  not be the subject of any stop order, unless the parties shall have
  mutually determined that registration under the Securities Act is not
  required with respect to the Recapitalization.
 
  The Recapitalization Merger Agreement provides that the obligation of
Alliance to effect the Recapitalization shall be subject to the satisfaction
or waiver, prior to the proposed Recapitalization Effective Time, of the
following conditions: All of the representations and warranties of the
Investor and Newco set forth in the Recapitalization Merger Agreement shall be
true and correct in all material respects as of the date of the
Recapitalization Merger Agreement and (except for those that are expressly
made only as of another date) as of the Recapitalization Effective Time as
though made on and as of such time, and the Investor and Newco shall have
performed in all material respects all covenants and agreements required to be
performed by them under the Recapitalization Merger Agreement at or prior to
the Recapitalization Effective Time.
 
  The Recapitalization Merger Agreement provides that the obligations of the
Investor and Newco to effect the Recapitalization shall be subject to the
satisfaction or waiver by the Investor and Newco, prior to the proposed
Recapitalization Effective Time, of the following conditions:
 
    (a) All of the representations and warranties of Alliance set forth in
  the Recapitalization Merger Agreement shall be true and correct in all
  material respects as of the date thereof and (except for those that are
  expressly made only as of another date) as of the Recapitalization
  Effective Time as though made on and as of such time, and Alliance shall
  have performed in all material respects all covenants and agreements
  required to be performed by it under the Recapitalization Merger Agreement
  at or prior to the Recapitalization Effective Time.
 
    (b) None of the following shall have occurred: (i) any general suspension
  of trading in, or limitation on prices for, securities on the New York
  Stock Exchange or Nasdaq, (ii) a declaration of a banking moratorium or any
  suspension of payments in respect of banks in the United States or any
  limitation by federal or state authorities on the extension of credit by
  lending institutions, or a disruption of or material adverse change in
  either the syndication market for credit facilities or the financial,
  banking or capital markets, (iii) a commencement of a war or armed
  hostilities or other national or international calamity directly or
  indirectly involving the United States or (iv) in the case of any of the
  foregoing existing as of July 23, 1997, a material acceleration or
  worsening thereof.
 
    (c) There shall not have occurred any material adverse change.
 
    (d) The conditions set forth in the Financing Letters (as defined in the
  Recapitalization Merger Agreement) shall have been satisfied or waived and
  the funding referred to therein shall be available to the Investor and
  Newco on terms no less favorable to the Investor and Newco than are set
  forth in such Financing Letters, unless the failure of such conditions to
  be satisfied or waived, or the non-availability of such funds, is caused

    (e) All filings required to be made prior to the Recapitalization
  Effective Time with, and all consents, approvals, authorizations and
  permits required to be obtained prior to the Recapitalization Effective
  Time from, any governmental entity in connection with the consummation of
  the Recapitalization have been made and/or obtained, other than those the
  failure of which to be made and/or obtained would not reasonably be
  expected to have a material adverse effect on, or prevent or materially
  delay the consummation of, the Recapitalization.
 
    (f) All notices required to be given prior to the Recapitalization
  Effective Time with, and all consents, approvals, authorizations, waivers
  and amendments required to be obtained prior to the Recapitalization
  Effective Time from, any third party in connection with the consummation of
  the Recapitalization and the finances thereof have been made and/or
  obtained (or, if the notice, consent, approval, authorization, waiver or
  amendment that is not so made and/or obtained is required pursuant to the
  terms of any of Alliance's indebtedness or obligations for money borrowed,
  Alliance has repaid such indebtedness or obligation on or prior to the
  Recapitalization Effective Time), other than those the failure of which to
  be made and/or obtained would not reasonably be expected to have a material
  adverse effect on, or prevent or materially delay the consummation of, the
  Recapitalization; provided that Alliance shall have obtained the consents
  set forth on Schedule 7.3(f) of the Recapitalization Merger Agreement.
 
    (g) The Investor shall have received advice from Ernst & Young LLP that
  the Recapitalization will qualify for recapitalization accounting treatment
  in accordance with generally accepted accounting principles consistently
  applied.
 
    (h) Alliance shall have taken appropriate steps to arrange for the
  payment or prepayment of capital leases, promissory notes and other loan or
  financing obligations (collectively, "Obligations"; provided, that such
  term shall not include (i) obligations under operating leases classified as
  such in accordance with generally accepted accounting principles or (ii)
  any obligations incurred from and after October 1, 1997) to which Alliance
  or any subsidiary thereof is a party or by which the assets or properties
  of Alliance or any subsidiary thereof is a party or by which the assets or
  properties of Alliance or any subsidiary thereof are bound (including those
  in respect of MRI Units and CT Units), such that, immediately following the
  Recapitalization Effective Time (and assuming the receipt of equity and
  debt financing by Alliance in connection with the Recapitalization, as
  contemplated by the Recapitalization Merger Agreement), Alliance will be
  able to pay (or prepay) the aggregate amount of all such Obligations,
  including the amount of any prepayment penalties or similar payments
  related thereto (but excluding from such aggregate amount (i) no more than
  an aggregate principal amount of $10 million of Obligations that Alliance
  elects to leave outstanding (the "Carryover Obligations") and (ii) accrued
  interest on the Obligations being paid), for an amount not to exceed $76
  million (assuming that all regular payments due on or before October 1,
  1997 in respect of the Obligations have been paid); provided, further, that
  (x) the consummation of the Recapitalization Merger will neither give rise
  to a right of acceleration of, nor constitute an event of default under the
  terms of, any Carryover Obligations, except, in either case, as set forth
  in Schedule 7.3(h) of the Recapitalization Merger Agreement and (y)
  Alliance will not incur additional indebtedness or financing obligations
  (again, excluding operating leases) during the fourth quarter of 1997 in
  excess of an aggregate principal or face amount thereof equal to $11
  million.
 
    (i) The holders of less than 10% of the outstanding shares of Alliance
  Common Stock shall have validly elected to demand the appraisal of their
  shares of Alliance Common Stock pursuant to Section 262 of the DGCL.
 
  Subject to applicable law, each of the conditions, other than the condition
requiring stockholder approval, may be waived. Alliance does not intend to
resolicit a vote of its stockholders on the Recapitalization Merger Agreement
in the event any material conditions are waived. However, the Investor has
agreed, pursuant to the Stockholder Agreement, not to waive any condition so
as to reduce the value of the consideration payable in the Recapitalization,
materially adversely affect the timing of the closing of the Recapitalization,
reduce the Cash Merger Price or otherwise adversely affect the interests of
the Principal Stockholders.
 
  Conduct of Business. The Recapitalization Merger Agreement provides that
until the Recapitalization Effective Time, subject to certain exceptions,
Alliance shall, and shall cause each of its subsidiaries to, carry on
 
                                      65

reasonable efforts to preserve intact its current business organization, keep
available the services of its current officers and employees and preserve its
relationships with customers, suppliers, licensors, licensees and others
having significant business dealings with it. The Recapitalization Merger
Agreement further provides that without limiting the generality of the
foregoing, until the Recapitalization Effective Time, Alliance shall not and
shall cause each of its subsidiaries not to (except as expressly permitted by
the Recapitalization Merger Agreement or with the Investor's consent, which
consent shall be deemed given after Investor's receipt of Alliance's written
request for a waiver of a covenant, which request has not been rejected in
writing by the Investor within three days after Investor's signed receipt
thereof by overnight courier service):

<PAGE>
 
Investor has sufficient sources of liquid capital funds, and concurrently with
the Recapitalization Effective Time will fund, in cash, at least $55.0 million
in equity capital. The Investor delivered financing letters to the Company and
further represented and warranted that, assuming satisfaction of all
conditions set forth in such financing letters and full funding thereunder,
such financing, together with the New Equity Investment and proceeds from the
issuance of the Series F Preferred Stock and pursuant to a senior bank term
loan facility, will provide sufficient funds to finance the Recapitalization
and pay certain related fees and expenses.
 
  Indemnification, Exculpation and Insurance. The Investor has agreed that all
rights to indemnification and exculpation (including the advancement of
expenses) from liabilities for acts or omissions occurring at or prior to the

of the Recapitalization Merger Agreement in favor of the current or former
directors, officers and employees of Alliance, as provided in Alliance's or
any of its Subsidiaries' Certificate of Incorporation and/or its By-laws
and/or any indemnification agreements and pursuant to applicable law, shall be
assumed by the Recapitalized Company in the Recapitalization, without further
action, as of the Recapitalization Effective Time and shall survive the
Recapitalization and shall continue in full force and effect without

of not less than five years after the Recapitalization Effective Time;

all rights to indemnification (and to advancement of expenses) under the
Recapitalization Merger Agreement in respect of any such claims shall
continue, without diminution, until disposition of any and all such claims.
 
  The Recapitalization Merger Agreement provides that for a period of at least
five years after the Recapitalization Effective Time, the Recapitalized
Company shall cause to be maintained in effect standard policies of directors'

necessary, proper or advisable to consummate and make effective, in the most
expeditious manner practicable, the Recapitalization and the other
transactions contemplated by the Recapitalization Merger Agreement.
 
  Guaranty. AIF III has unconditionally and irrevocably guaranteed the
obligations of the Investor under the Recapitalization Merger Agreement in an
amount not to exceed $37.0 million. Such guaranty terminates upon the earlier
of (a) the consummation of the Recapitalization and (b) subject to certain
exceptions relating primarily to a breach of the Recapitalization Merger

                          CERTAIN RELATED AGREEMENTS
 
STOCKHOLDER AGREEMENT
 
  The following is a brief summary of certain provisions of the Stockholder
Agreement, a copy of which appears as Annex B to this Proxy
Statement/Prospectus and is incorporated herein by reference. Such summary is
qualified in its entirety by reference to this Stockholder Agreement.
 
  Pursuant to the Stockholder Agreement, Principal Stockholders owning
approximately 54.4% of the issued and outstanding shares of Alliance Common
Stock (66% assuming the exercise by such Principal Stockholders and no others
of all securities convertible into or exercisable for shares of Common Stock
immediately prior to the Recapitalization Effective Time) have granted to the
Investor the option to acquire (i) all shares of Alliance Common Stock owned
by such Principal Stockholders, (ii) any other shares of Alliance Common Stock
acquired by the Principal Stockholders during the term of the Stockholder
Agreement (including without limitation, through the conversion of any
convertible security or the exercise of any Alliance Stock Option or Warrants)
(collectively, the "Subject Shares") for a purchase price per share of $11.00
in cash. The option is currently exercisable and terminates, in general, upon
termination of the Stockholder Agreement, which, subject to certain
exceptions, will be December 31, 1997 or earlier if the Recapitalization
Merger Agreement is terminated.
 
  Each Principal Stockholder has further agreed (and the Stockholder Agreement
includes an irrevocable proxy for the benefit of the Investor with respect to
the shares of Alliance capital stock subject to the Stockholder Agreement
owned by each Principal Stockholder) (1) to vote all Subject Shares
beneficially owned by such persons at any meeting of Alliance's stockholders
or at any adjournment thereof or in any other circumstances upon which a vote,
consent or other approval (including by written consent) with respect to the
Recapitalization and the Recapitalization Merger Agreement is sought, in favor
of the adoption of the Recapitalization Merger Agreement and the
Recapitalization and (2) to vote such Subject Shares of Alliance Common Stock
at any meeting of stockholders of Alliance or at any adjournment thereof or in
any other circumstances upon which a stockholder's vote, consent or other
approval is sought, against (x) any Alternative Transaction, (y) any amendment
of Alliance's certificate of incorporation or by-laws or other proposal or
transaction involving Alliance, which amendment or other proposal or
transaction would be reasonably likely to impede, frustrate, prevent or
nullify the Recapitalization Merger Agreement, the Recapitalization or any of
the transactions contemplated by the Recapitalization Merger Agreement or
change in any manner the voting rights of each class of Alliance's capital
stock or (z) any action that would cause Alliance to breach any
representation, warranty or covenant contained in the Recapitalization Merger
Agreement.
 
  Each Principal Stockholder has also agreed, until the Stockholder Agreement
has terminated, among other things, not to: (1) sell, transfer, give, pledge
or otherwise dispose of, or enter into any contract, option or other
arrangement with respect to the sale, transfer, pledge, assignment or other
disposition of, the subject shares owned by such Principal Stockholder other
than pursuant to the terms of the Recapitalization Merger Agreement; (2) enter
into any voting arrangement, whether by proxy, voting agreement or otherwise,
in connection with, directly or indirectly, any Alternative Transaction; (3)
directly or indirectly solicit, initiate or encourage the submission of, any
proposal that may lead to an Alternative Transaction; or (4) directly or
indirectly participate in any discussions or negotiations regarding, or
furnish to any person any information with respect to, 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 Alternative
Transaction (or, in each case, permit any investment banker, financial
advisor, attorney, accountant or other representative retained by it to do any
of the foregoing).
 
EMPLOYMENT AGREEMENTS AND AGREEMENT NOT TO COMPETE
 
  The following are brief summaries of the Employment Agreements and the
Agreement Not to Compete, copies of which are filed as exhibits to the
Registration Statement on Form S-4. Such summaries are qualified in their
entirety by reference to such exhibits.
 
  Employment Agreements. Alliance has entered into an Employment Agreement
with Richard N. Zehner to act as Chief Executive Officer and with Vincent S.
Pino to act as Chief Operating Officer. Base compensation under the Employment
Agreements is $315,000 per year for Mr. Zehner and $275,000 per year for Mr.
Pino, subject in each case to increase by the Board of Directors. In addition,
Mr. Zehner and Mr. Pino are entitled to
 
                                      69
<PAGE>
 
receive an annual cash bonus based upon Alliance's achievement of certain
operating and/or financial goals, with an annual target bonus amount equal to
a specified percentage of their then current annual base salary (75% in the
case of Mr. Zehner and 60% in the case of Mr. Pino). Such bonus plan will be
adopted and administered by the compensation committee of the Board of
Directors (the "Compensation Committee"). In connection with the Employment
Agreements, Mr. Zehner and Mr. Pino are entitled to receive 145,000 and
130,000 options, respectively, under the New Stock Option Plan described
below.
 
  The term of each Employment Agreement is initially three years. After the
first year, the Agreements will have a term of two years, with automatic
extensions for additional three month periods if neither party gives notice
that the term will not be so extended. Alliance may terminate Mr. Zehner's or
Mr. Pino's employment at any time and for any reason and Mr. Zehner and Mr.
Pino may resign at any time and for any reason.
 
  Agreement Not to Compete. In connection with the Recapitalization Merger
Agreement, Mr. Zehner and Mr. Pino have entered into an agreement with the
Investor that contains, among other things, covenants not to compete with
Alliance. Pursuant to such covenants, Mr. Zehner and Mr. Pino have each agreed
that they will not, prior to the later of five years following the
Recapitalization Effective Time and two years after the date of their
termination, (i) engage in any Competitive Business in the United States or
(ii) compete or participate as an agent, consultant, advisor, representative,
owner, investor or otherwise in any enterprise engaged in a Competitive
Business in the United States. Ownership of less than 5% of a publicly-traded
entity engaged in a Competitive Business would not be a violation of the
covenant to compete. For these purposes, "Competitive Business" means any
imaging business or other business that becomes material to Alliance during
the term of Mr. Zehner's or Mr. Pino's employment.
 
  In addition, prior to 24 months after the later of the date of termination
of employment or the date of ceasing to receive payments under the agreement
not to compete, Mr. Zehner and Mr. Pino, as the case may be, have each agreed
not to make any contact with any customer of Alliance with respect to the
provision of any service that is the same or substantially similar to any
service provided to such customer by Alliance. Furthermore, prior to 12 months
after the later of the date termination of employment or the date of ceasing
to receive payments under the covenant not to compete, Mr. Zehner and Mr.
Pino, as the case may be, have each agreed not to solicit or make any contact
with any employee of Alliance with respect to any employment, service or other
business relationship. Pursuant to such agreement, Alliance has agreed to make
certain payments to Messrs. Zehner and Pino following the termination of their
employment. However, in the event of a termination for cause, or due to death
or disability or a resignation without good reason (as defined in the
Employment Agreements), Alliance will be under no obligation to make such
payments.
 
THE NEW OPTION PLAN
 
  After the consummation of the Recapitalization, the Company will adopt an
employee option plan pursuant to which options (the "New Options") with
respect to a total of 454,545 shares of Alliance Common Stock (the "New Option
Shares") will be available for grant. The New Option Shares will be allocated
in amounts agreed upon between the Investor and the Company. Richard Zehner
will be allocated New Options to acquire 145,000 New Option Shares; Vincent
Pino will be allocated New Options to acquire 130,000 New Option Shares. Fifty
percent of the New Option Shares will vest in equal increments over four
years. Fifty percent of the New Option Shares will vest after seven and one
half years (subject to acceleration if certain per-share equity targets are
achieved). Vesting of New Options occurs only during an employee's term of
employment. The exercise price for the New Options is $11.00 per share and the
New Options will expire ten years from the date of grant.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  At the Recapitalization Effective Time, Alliance will pay to Apollo
Management L.P. a fee of $2.5 million in connection with arranging the
transactions contemplated by the Recapitalization (including the financings
thereof). Thereafter, the Company will pay Apollo Management, L.P. an annual
management fee of $500,000 and will continue to receive financial advisory
services from Apollo Management L.P. on an ongoing basis, with compensation to
be determined. In connection with the Transactions, Apollo will purchase $15.0
million of the Company's Series F Preferred Stock and will receive a financing
fee of $600,000. Immediately after consummation of the Transactions, Apollo
intends to sell to BT $0.9 million stated amount of the Series F Preferred
Stock purchased by it for $0.9 million in cash. In connection with such sale,
Apollo will pay to BT $36,000 of the $600,000 financing fee.
 
  Pursuant to an engagement letter, Alliance will pay Salomon Brothers the
following fees: (a) $100,000, which was earned upon Alliance's execution of
the Recapitalization Merger Agreement; plus (b) an additional fee of $400,000,
which was earned upon the initial submission of Salomon Brothers' fairness
opinion to the Board of Directors on July 22, 1997; plus (c) an additional fee
of $2.4 million, which is contingent upon the consummation of the
Recapitalization and payable at the closing thereof. In addition, Salomon
Brothers will be an underwriter in the Offering and a lender under the Credit
Agreement.
 
  BT Alex. Brown Incorporated, an affiliate of BT, will be an underwriter in
the Offering, will be an agent and lender under the Credit Agreement. BT will
purchase approximately $2.7 million of Alliance Common Stock from Apollo
concurrently with the consummation of the Recapitalization.
 
 
  For a description of certain management arrangements in connection with the
Recapitalization, see "THE RECAPITALIZATION--Interests of Certain Persons in
the Recapitalization" and "MANAGEMENT--Employment and Related Agreements."
 
                             REGULATORY APPROVALS
 
  The Recapitalization is subject to the expiration or termination of the
applicable waiting period under the HSR Act. Certain aspects of the
Recapitalization will require notification to, and filings with, certain
governmental authorities, including jurisdictions where Alliance currently
operates.
 
ANTITRUST
 
  Under the HSR Act and the rules promulgated thereunder by the Federal Trade
Commission (the "FTC"), the Recapitalization may not be consummated until
notifications have been filed with the FTC and the Antitrust Division of the
Department of Justice (the "Antitrust Division") and the applicable waiting
period has expired or been terminated. On August 13, 1997, Alliance and the
Investor filed Notification and Report Forms for the Recapitalization under
the HSR Act with the FTC and the Antitrust Division and the waiting period
under the HSR Act has expired. At any time before or after the
Recapitalization Effective Time, notwithstanding that the waiting period under
the HSR Act has expired the Antitrust Division or the FTC could take such
action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking to enjoin the consummation of the
Recapitalization or seeking divestiture of substantial assets of Alliance. At
any time before or after the Recapitalization Effective Time, and
notwithstanding that the waiting period under the HSR Act has expired, any
state could take such action under the antitrust laws as it deems necessary or
desirable in the public interest. Such action could include seeking to enjoin
the consummation of the Recapitalization or seeking divestiture of substantial
assets of Alliance. Private parties may also seek to take legal action under
the antitrust laws under certain circumstances.
 
  Based on information available to them, Alliance and Newco believe that the
Recapitalization can be effected in compliance with federal and state
antitrust laws. However, there can be no assurance that a challenge to the
consummation of the Recapitalization on antitrust grounds will not be made or
that, if such a challenge were made, Alliance and Newco would prevail or would

  The obligations of the Investor under the Recapitalization Merger Agreement
are also subject to the receipt of all necessary licenses, permits, consents,
approvals, authorizations, qualifications and orders of governmental
authorities and other third parties as are necessary in connection with the
transactions contemplated by the Recapitalization.
 
                        DISSENTING STOCKHOLDERS' RIGHTS
 
  Holders of shares of Alliance Common Stock who do not vote in favor of the
Recapitalization Merger Agreement and who properly demand appraisal of their
shares will be entitled to appraisal rights in connection with the
Recapitalization under Section 262 of the DGCL.
 
  The obligations of the Investor under the Recapitalization Merger Agreement
are conditioned upon holders of less than 10% of the outstanding shares of
Alliance Common Stock having validly elected to demand the appraisal of their
shares pursuant to Section 262 of the DGCL.
 
  THE FOLLOWING DISCUSSION IS NOT A COMPLETE STATEMENT OF THE LAW PERTAINING
TO APPRAISAL RIGHTS UNDER THE DGCL AND IS QUALIFIED IN ITS ENTIRETY BY THE
FULL TEXT OF SECTION 262 WHICH IS ATTACHED TO THIS PROXY STATEMENT/PROSPECTUS
AS ANNEX D. ALL REFERENCES IN SECTION 262 AND IN THIS SUMMARY TO A
"STOCKHOLDER" ARE TO THE RECORD HOLDER OF THE SHARES OF ALLIANCE COMMON STOCK
AS TO WHICH APPRAISAL RIGHTS ARE ASSERTED. A PERSON HAVING A BENEFICIAL
INTEREST IN SHARES OF ALLIANCE COMMON STOCK HELD OF RECORD IN THE NAME OF
ANOTHER PERSON, SUCH AS A BROKER OR NOMINEE, MUST ACT PROMPTLY TO CAUSE THE
RECORD HOLDER TO FOLLOW THE STEPS SUMMARIZED BELOW PROPERLY AND IN A TIMELY
MANNER TO PERFECT APPRAISAL RIGHTS.
 
  Under the DGCL, holders of shares of Alliance Common Stock who follow the
procedures set forth in Section 262 will be entitled to have their shares of
Alliance Common Stock appraised by the Delaware Court of Chancery and to
receive payment of the "fair value" of such shares, exclusive of any element
of value arising from the accomplishment or expectation of the
Recapitalization, together with a fair rate of interest, as determined by such
court.
 
  Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the case of the Special Meeting, the
corporation, not less than 20 days prior to the meeting, must notify each of
its stockholders entitled to appraisal rights that such appraisal rights are
available and include in such notice a copy of Section 262. This Proxy
Statement/Prospectus shall constitute such notice to the holders of shares of
Alliance Common Stock, and the applicable statutory provisions are attached to
this Proxy Statement/Prospectus as Annex D. Any holder of shares of Alliance
Common Stock who wishes to exercise such appraisal rights or who wishes to
preserve such holder's right to do so should review the following discussion
and Annex D carefully because failure to timely and properly comply with the
procedures specified will result in the loss of appraisal rights under the
DGCL.
 
  A holder of shares of Alliance Common Stock wishing to exercise appraisal
rights must deliver to Alliance, before the vote on the Recapitalization at
the Special Meeting, a written demand for appraisal and must not vote in favor
of the Recapitalization. Because a duly executed proxy which does not contain
voting instructions will, unless revoked, be voted for the Recapitalization, a
holder of shares of Alliance Common Stock who votes by proxy and who wishes to
exercise appraisal rights must either (1) vote against the Recapitalization or
(2) abstain from voting on the Recapitalization. A vote against the
Recapitalization, in person or by proxy, will not in and of itself constitute
a written demand for appraisal satisfying the requirements of Section 262. In
addition, a holder of shares of Alliance Common Stock wishing to exercise
appraisal rights must hold of record such shares on the
 
                                      72
<PAGE>
 
date the written demand for appraisal is made and must continue to hold such
shares until the Recapitalization Effective Time. If any holder of shares of
Alliance Common Stock fails to comply with any of these conditions and the
Recapitalization becomes effective, the holder of shares of Alliance Common
Stock will be entitled to receive the consideration receivable with respect to
such shares in the absence of a valid assertion of appraisal rights in
accordance with the Recapitalization Merger Agreement.
 
  Only a holder of record of shares of Alliance Common Stock is entitled to
assert appraisal rights for the shares of Alliance Common Stock registered in
that holder's name. A demand for appraisal should be executed by or on behalf
of the holder of record, fully and correctly, as such holder of record's name
appears on such holder of record's stock certificates, and must state that the
stockholder intends thereby to demand appraisal of such stockholder's shares
in connection with the Recapitalization. If the shares of Alliance Common
Stock are owned of record in a fiduciary capacity, such as by a trustee,
guardian or custodian, execution of the demand should be made in that
capacity, and if the shares of Alliance Common Stock are owned of record by
more than one person, as in a joint tenancy and tenancy in common, the demand
should be executed by or on behalf of all joint owners. An authorized agent,
including two or more joint owners, may execute a demand for appraisal on
behalf of a holder of record; however, the agent must identify the record
owner or owners and expressly disclose the fact that, in executing the demand,
the agent is agent for such owner or owners. A record holder such as a broker
who holds shares of Alliance Common Stock as nominee for several beneficial
owners may exercise appraisal rights with respect to the shares of Alliance
Common Stock held for one or more beneficial owners while not exercising such
rights with respect to the shares of Alliance Common Stock held for other
beneficial owners. Stockholders who hold their shares of Alliance Common Stock
in brokerage accounts or other nominee forms and who wish to exercise
appraisal rights are urged to consult with their brokers to determine the
appropriate procedures for making of a demand for appraisal by such a nominee.
 
  All written demands for appraisal pursuant to Section 262 should be sent or
delivered to Alliance at 1065 North PacifiCenter Drive, Suite 200, Anaheim, CA
92806, Attention: Richard N. Zehner.
 
  Within 10 days after the Recapitalization Effective Time, Alliance, as the
surviving corporation, must notify each holder of shares of Alliance Common
Stock who has complied with Section 262 and has not voted in favor of or
consented to the Recapitalization of the date that the Recapitalization has
become effective. Within 120 days after the Recapitalization Effective Time,
but not thereafter, Alliance or any holder of shares of Alliance Common Stock
who is entitled to appraisal rights under Section 262 may file a petition in
the Delaware Court of Chancery demanding a determination of the fair value of
such holder's shares of Alliance Common Stock. Notwithstanding the foregoing,
at any time within 60 days after the Recapitalization Effective Time, any
stockholder has the right to withdraw his demand for appraisal and to accept
the terms offered in respect of the Recapitalization. Alliance is under no
obligation to and has no present intention to file such a petition.
Accordingly, it is the obligation of the holders of shares of Alliance Common
Stock to initiate all necessary action to perfect their appraisal rights
within the time prescribed in Section 262.
 
  Within 120 days after the Recapitalization Effective Time, any holder of
shares of Alliance Common Stock who has complied with the requirements for
exercise of appraisal rights will be entitled, upon written request, to
receive from Alliance a statement setting forth the aggregate number of shares
of Alliance Common Stock not voted in favor of the Recapitalization and with
respect to which demands for appraisal have been received and the aggregate
number of holders of such shares. Such statement must be mailed to the
stockholders within ten days after a written request therefor has been
received by Alliance or within ten days after the expiration of the period for
delivery of demands for appraisal, whichever is later.
 
  If a petition for an appraisal is timely filed by a holder of shares of
Alliance Common Stock and a copy thereof is served upon Alliance, Alliance
will then be obligated within 20 days to file with the Delaware Register in
Chancery a duly verified list containing the names and addresses of all
holders of shares of Alliance Common Stock who have demanded an appraisal of
their shares and with whom agreements as to the value of their shares have not
been reached. After notice to such stockholders as required by the Court, the
Delaware Court of Chancery is empowered to conduct a hearing on such petition
to determine those holders of shares of Alliance
 
                                      73
<PAGE>
 
Common Stock who have complied with Section 262 and who have become entitled
to appraisal rights thereunder. The Delaware Court of Chancery may require the
holders of shares of Alliance Common Stock who demanded payment for their
shares to submit their stock certificates to the Register in Chancery for
notation thereon of the pendency of the appraisal proceeding; and if any
stockholder fails to comply with such direction, the Court of Chancery may
dismiss the proceedings as to such stockholder.
 
  After determining the holders of shares of Alliance Common Stock entitled to
appraisal, the Delaware Court of Chancery will appraise the "fair value" of
their shares of Alliance Common Stock, exclusive of any element of value
arising from the accomplishment or expectation of the Recapitalization,
together with a fair rate of interest, if any, to be paid upon the amount
determined to be the fair value. Holders of shares of Alliance Common Stock
considering seeking appraisal should be aware that the fair value of their
shares of Alliance Common Stock as determined by Section 262 could be more
than, the same as or less than the consideration they would receive pursuant
to the Recapitalization if they did not seek appraisal of their shares of
Alliance Common Stock and that investment banking opinions as to fairness from
a financial point of view are not necessarily opinions as to fair value under
Section 262. The Delaware Supreme Court has stated that "proof of value by any
techniques or methods which are generally considered acceptable in the
financial community and otherwise admissible in court" should be considered in
the appraisal proceedings. In addition, Delaware courts have decided that the
statutory appraisal remedy, depending on factual circumstances, may or may not
be a dissenter's exclusive remedy. The Court of Chancery will also determine
the amount of interest, if any, to be paid upon the amounts to be received by
persons whose shares of Alliance Common Stock have been appraised. The costs
of the action may be determined by the Court and taxed upon the parties as the
Court deems equitable. The Court may also order that all or a portion of the
expenses incurred by any stockholder in connection with an appraisal,
including, without limitation, reasonable attorneys' fees and the fees and
expenses of experts utilized in the appraisal proceeding, be charged pro rata
against the value of all the shares of Alliance Common Stock entitled to be
appraised.
 
  Any holder of shares of Alliance Common Stock who has duly demanded an
appraisal in compliance with Section 262 will not, after the Effective Time,
be entitled to vote the shares of Alliance Common Stock subject to such demand
for any purpose or be entitled to the payment of dividends or other
distributions on those shares of Alliance Common Stock (except dividends or
other distributions payable to holders of record of shares of Alliance Common
Stock as of a date prior to the Recapitalization Effective Time).
 
  If any stockholder who demands appraisal of such stockholder's shares of
Alliance Common Stock under Section 262 fails to perfect, or effectively
withdraws or loses, such stockholder's right to appraisal, as provided in the
DGCL, the shares of Alliance Common Stock of such stockholder will be
converted into the right to receive the Cash Merger Price pursuant to the
Recapitalization Merger Agreement (without interest). A stockholder will fail
to perfect, or effectively lose or withdraw, such stockholder's right to
appraisal if no petition for appraisal is filed by such holder within 120 days
after the Recapitalization Effective Time, or if the stockholder delivers to
Alliance a written withdrawal of his, hers or its demand for appraisal and an
acceptance of the Recapitalization, except that any such attempt to withdraw
made more than 60 days after the Recapitalization Effective Time will require
the written approval of Alliance and, once a petition for appraisal is filed,
the appraisal proceeding may not be dismissed as to any holder absent court
approval. It is not necessary that each holder of shares of Alliance Common
Stock properly demanding appraisal file a petition for appraisal in the
Delaware Court of Chancery. Rather, a single valid petition suffices for the
petitioning and non-petitioning holders of shares of Alliance Common Stock who
have properly demanded appraisal.
 
  FAILURE TO FOLLOW THE STEPS REQUIRED BY SECTION 262 OF THE DGCL FOR
PERFECTING APPRAISAL RIGHTS MAY RESULT IN THE LOSS OF SUCH RIGHTS (IN WHICH
EVENT A STOCKHOLDER WILL BE ENTITLED TO RECEIVE THE CASH MERGER PRICE IN
ACCORDANCE WITH THE RECAPITALIZATION MERGER AGREEMENT FOR EACH SHARE OF
ALLIANCE COMMON STOCK OWNED BY SUCH STOCKHOLDER).

            UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
 
  The following unaudited pro forma combined consolidated balance sheet at
September 30, 1997 reflects the historical consolidated balance sheet of
Alliance adjusted to give effect to the Transactions as if they had occurred
at September 30, 1997. The Recapitalization will be treated as a leveraged
recapitalization in which there will be no changes to the carrying values of
Alliance's net assets and the sales and purchases of Alliance's common stock
will be accounted for as capital transactions at amounts received from or paid
to stockholders.
 
  The following unaudited pro forma consolidated statements of operations for
the nine months ended September 30, 1997 and the year ended December 31, 1996,
respectively, reflect the historical operations of Alliance adjusted to give
effect to the Transactions as if they had occurred as of January 1, 1997 for
the nine months ended September 30, 1997, and as of January 1, 1996 for the
year ended December 31, 1996.
 
  The unaudited pro forma consolidated financial information is based on the
consolidated financial statements of Alliance giving effect to the
Transactions under the assumptions and adjustments outlined in the
accompanying Notes to Unaudited Pro Forma Consolidated Financial Information.
Such pro forma adjustments are based upon available information and upon
certain assumptions that the Company's management believes are reasonable
under the circumstances. The unaudited pro forma consolidated balance sheet
and statements of operations are provided for comparative purposes only and do
not purport to represent the results that would have been obtained had the
Transactions occurred on the dates indicated or that may be achieved in the
future.

 * Alliance's Series D Convertible Preferred Stock will be converted into
  shares of Alliance Common Stock prior to the closing of the Transactions.
** Estimated cash used to settle outstanding employee stock options and change
  in control payments.
 
  The gross amount to be paid for Alliance Common Stock is $154.3 which
represents the $11.00 per share repurchase price multiplied by 14,023,344
total shares. The total of 14,023,344 shares is comprised of the sum of: (1)
11,023,344 shares of Alliance Common Stock outstanding as of September 30,
1997; and (2) 3,000,000 shares of Alliance Common Stock to be issued with
respect to the conversion of all outstanding shares of Alliance Series D
Convertible Preferred Stock. The gross amount is then increased by $2.1
million in payment of the net value of warrants canceled and reduced by $4.5
million (411,358 shares at $11.00 per share) with respect to the retained
shares, and $18.0 million related to the carrying value of Alliance's
preferred equity converted to common shares, resulting in a net payment for
Alliance equity of $133.8 million.
 
  (f) Reflects the sale of $15.0 million of the Company's Series F Preferred
Stock to the Investor. The Series F Preferred Stock is required to be redeemed
by the Company ten years from its issue date at its stated value plus accrued
and unpaid dividends. It may also be redeemed at the option of the Company at
any time after its issue date at premiums declining over ten years from 13.5%
(expressed as a percentage of the accreted face value) to 0%.

    administrative cost savings, primarily related to investor relations and
    board of directors fees and expenses.
 
(b) Non-recurring charges aggregating $20.9 million (comprised of $11.7
    million used to settle outstanding employee stock options and other change
    in control payments and $13.8 million of transaction costs net of $1.0
    million gain on repayment of debt and $3.6 million of estimated tax

(c) Reflects amortization of deferred financing fees associated with the
    Transactions.
 
(d) Interest expense, as adjusted, reflects the elimination of historical

  A 1/8% variance in interest rates would change annual interest expense by
     approximately $246,000.
 
(e) Income tax adjustments reflect estimated effective tax rates applied to
    the pro forma adjustments excluding book/tax differences associated with
    nondeductible amortization expense. In accordance with FAS 109,
    "Accounting for Income Taxes," due to the occurrence of losses before
    income taxes and extraordinary items, no tax benefits have been recorded.
 
(f) The preferred stock dividend is calculated based on a 13.50% paid-in-kind
    rate compounded quarterly, plus amortization of $0.6 million of related
    financing fees over the ten year term of the preferred stock.
 
(g) The weighted average common shares outstanding includes 4,043,580 common
    share issued in connection with the Transactions (3,632,222 to the
    Investor and 411,358 to the existing shareholders), and excludes 70,000
    rollover option shares, net of 22,670 shares repurchased using the
    treasury stock method because such shares would be anti-dilutive.
 
(h) Pro forma earnings were insufficient to cover fixed charges by $8.3
    million for the year ended December 31, 1996, and $0.7 million for the
    nine months ended September 30, 1997.

    it is a widely accepted financial indicator of a company's ability to
    service and/or incur indebtedness. However, EBITDA should not be
    considered as an alternative to net income as a measure of operating
    results or to cash flows as a measure of liquidity in accordance with
    generally accepted accounting principles.
(3) EBITDA margin is defined herein as EBITDA divided by revenues. The Company

    interest factor. Earnings were insufficient to cover fixed charges by
    $20.0 million and $18.0 million for the years ended December 31, 1993 and
    1994, respectively.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion of the results of operations and financial
condition of Alliance should be read in conjunction with Alliance's
consolidated financial statements and notes thereto included elsewhere in this
Proxy Statement/Prospectus.
 
OVERVIEW
 
  The Company is a leading nationwide provider of diagnostic imaging services
and the largest operator of state-of-the-art mobile diagnostic imaging systems
and related outsourced radiology services in the United States. The Company
primarily provides MRI systems and services to hospitals and other health care
providers on a mobile, shared user basis. The Company also provides dedicated,
full-time MRI systems and services as well as full-service management of
imaging operations for selected hospitals. The Company's services enable small
to mid-size hospitals to gain access to advanced diagnostic imaging technology
and related value-added services without making a substantial investment in
equipment and personnel. The Company operates a fleet of 98 MRI systems and
services 356 MRI customers in 36 states under exclusive contracts with an
average remaining length of approximately 24 months as of September 30, 1997.
 
  The Company's revenues are principally a function of the number of systems
in service, scan volumes and fees per scan. The Company generates
substantially all of its revenues under exclusive one to eight-year contracts
with hospitals and health care providers. The Company's contracts typically
offer tiered pricing with lower fees per scan on incremental scans, allowing
customers to benefit from increased scan volumes and the Company to benefit
from the operating leverage associated with increased scan volumes. The
Company expects modest continuing downward pressure on pricing levels as a
result of cost containment measures in the health care industry. However, in
many cases higher scan volumes justify lower prices on incremental scans.
 
  The principal components of the Company's operating costs include salaries
paid to technologists and drivers, annual system maintenance costs, insurance
and transportation costs. Because a majority of these expenses are fixed,
increased revenues as a result of higher scan volumes significantly improve
the Company's profitability while lower scan volumes result in lower
profitability.
 
  Since the beginning of 1995, Alliance has substantially increased revenues
by adding new customers and increasing scan volumes at existing customer
sites. During the same period, the growth rate of Alliance's EBITDA and net
income increased more rapidly than the growth rate of revenues as a result of
spreading costs (which are primarily fixed) over a larger revenue base and
implementing cost reduction and containment measures.
 
  Alliance has historically focused on maximizing cash flow and return on
invested capital nationwide, deploying new and upgraded systems in high volume
markets and redeploying older, less advanced systems with lower carrying
values in lower volume markets. Alliance's ongoing equipment trade-in and
upgrade program has substantially improved the marketability and productivity
of its MRI systems. Because Alliance owns substantially all of its MRI
systems, it periodically evaluates its older, less marketable MRI systems to
determine if it is more beneficial to continue to use such systems in lower
volume markets, which are profitable but produce less revenue, or to trade in
such equipment in connection with new system purchases. Since January 1, 1995,
Alliance has invested approximately $78 million to upgrade and expand its
fleet and currently maintains one of the most advanced fleets in the industry.
 
  The Company also provides CT services and imaging systems. Revenues from CT
services and imaging systems accounted for less than 5% of the Company's
revenues for the year ended December 31, 1996.
 
  On July 23, 1997, Alliance entered into the Recapitalization Merger
Agreement, pursuant to which, among other things, a subsidiary of the
Investor, subject to the terms and conditions of the Recapitalization Merger
Agreement, will be merged with and into Alliance. Immediately following the
Recapitalization, Apollo will own
 
                                      85
<PAGE>
 
approximately 84% of the issued and outstanding common stock of Alliance and
Alliance's existing shareholders will own approximately 10%. See "THE
RECAPITALIZATION." The pro forma effect of the Transactions is set forth under
"UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION" and the notes thereto
included elsewhere in this Proxy Statement/Prospectus.
 
  On October 20, 1997, the Company announced execution of a definitive
agreement to acquire MCIC, a Cleveland, Ohio based provider of mobile MRI
services, CT services and other outsourced healthcare services. The
acquisition also includes MCIC's one-half interest in an operating joint
venture in Michigan. The purchase price consists of $13 million cash plus the
assumption of approximately $5 million in financing arrangements. MCIC
operates 14 mobile MRI systems and several other diagnostic imaging systems,
primarily in Ohio, Michigan, Indiana and Pennsylvania. The transaction was
completed on November 21, 1997. This transaction will be primarily funded from
existing cash reserves and debt assumed. Additional investments of this nature
may be made in the future (subject to certain conditions contained in the
Company's long-term financing arrangements) from a combination of cash
reserves, cash flow from operations, common or preferred equity and the
Revolving Loan Facility.
 
RESULTS OF OPERATIONS
 
NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1996.
 
  Revenues for the first nine months of 1997 were $62,285,000, an increase of
$13,188,000 or 26.9%, over 1996. This increase reflects a scan-based MRI
revenue increase of $11,706,000, or 26.9% ($2,515,000 or 5.8% as a result of
MRI operations acquired subsequent to the first quarter of 1996), resulting
from a 29.2% increase in total scan volume partially offset by a 1.8% decrease
in the average revenue realized per MRI scan. The average daily scan volume
per MRI system increased 7.5% to 7.2 from 6.7 in 1996. Management attributes
the volume increase to the Company's continuing MRI systems upgrade program,
which has enabled the Company to obtain new, long-term contracts from both
existing and new customers, and to the effect of marketing programs
implemented in early 1997. Management believes the decrease in average revenue
realized per scan is the result of: many customers achieving discount price
levels on incremental scan volumes; obtaining contracts with customers that
have high scan volumes which justify lower scan prices; and continuing
competitive pressure in the MRI service industry and cost containment efforts
by health care payors. CT revenues increased $782,000, or 29.4%, as a result
of internal growth and the fourth quarter 1996 acquisition of a small CT
business. Other revenues increased $548,000 primarily as a result of the
implementation in late 1996 of a program providing management services for a
large portfolio of imaging systems owned by others.
 
  The Company operated 98 MRI systems at September 30, 1997 compared to 86 MRI
systems at September 30, 1996. The average number of MRI systems operated by
the Company was 89 during the first nine months of 1997, compared to 84 during
the first nine months of 1996.
 
  Operating expenses, excluding depreciation, totaled $27,499,000 in the first
nine months of 1997, an increase of $3,950,000, or 16.8%, from the first nine
months of 1996. Payroll and related employee expenses increased $2,028,000, or
19.1%, primarily as a result of an increase in operating staffing levels
necessary to support revenue growth. Repairs and maintenance expense increased
$477,000, or 40.0%, due to an increased number of systems in service. Fuel and
other vehicle expenses collectively increased $387,000, or 36.8%, primarily
due to increasing fuel prices and the addition of new mobile MRI systems.
Preventative maintenance and cryogen contract expense increased $186,000, or
2.8%, due to the expiration of the warranties on an increased number of MRI
systems. Other operating expenses (including insurance, site fees, office
expenses, equipment rental, supplies and professional services) increased
$872,000, or 21.0%, as a result of the increased level of operations.
 
  Depreciation expense during the first nine months of 1997 totaled
$11,222,000, an increase of $2,052,000, or 22.4%, from the 1996 level
principally due to a higher amount of depreciable assets associated with
equipment additions and upgrades. Amortization expense during the first nine
months of 1997 increased $458,000, or 35.0%, over the 1996 period as a result
of goodwill amortization associated with recent business acquisitions.
 
                                      86
<PAGE>
 
  Selling, general and administrative expenses totaled $6,251,000 in the first
nine months of 1997, an increase of $1,372,000, or 28.1%, from the same period
in 1996. Professional services expenses increased $566,000, or 147.0%,
primarily due to costs associated with increased investor relations efforts
and merger and acquisition activity. Payroll and related expenses increased
$436,000, or 12.0%, primarily as a result of increased staffing levels
necessary to support the Company's increased level of operations. Other
expenses increased primarily as a result of expanded marketing programs and
costs associated with relocating the Company's corporate offices.
 
  Interest expense of $5,315,000 in the first nine months of 1997 was
$1,131,000, or 27.0%, higher than the same period in 1996, as a result of
higher average outstanding debt balances during 1997 as compared to 1996. This
increase was primarily related to the senior bridge loan (which was converted
into Series D convertible preferred stock on March 26, 1997) and to the
financing of several new imaging systems during the first nine months of 1997.
 
  An income tax provision of $3,480,000 was recorded in the first nine months
of 1997, which was higher than the tax provision recorded in the same period
in 1996 by $2,525,000, or 264.4%. The increase resulted from the increase in
income before taxes and an increase in the Company's effective tax rate. The
effective income tax rate increased to 34.0% in 1997 from 15.9% in 1996
because the Company's taxable income in 1997 is expected to exceed remaining
available net operating loss carryforwards.
 
  The Company's income before extraordinary gain was $6,751,000 in the first
nine months of 1997 compared to net income of $5,051,000 in the first nine
months of 1996, an increase of $1,700,000, or 33.7%, primarily attributable to
the increase in revenues achieved without a proportionate increase in costs
and administrative expenses. The Company reported an extraordinary gain, net
of income taxes, in the first quarter of 1997 of $1,332,000 on early
extinguishment of debt in January 1997.
 
  Earnings per common share directly related to operations totaled $0.48 in
the first nine months of 1997, compared to earnings per common share of $0.38
for the same period in 1996, an increase of 26.3%. Alliance reported an
extraordinary gain, net of income taxes, in the first quarter of 1997 of
$1,332,000, or $0.11 per common share, on early extinguishment of debt in
January 1997. In addition, Alliance recorded $1,906,000 or $0.16 per common
share related to the excess of the carrying amount of the Series A 6%
cumulative preferred stock repurchased over the consideration period in
January 1997. Although the preceding earnings per share amounts for the first
nine months of 1997 are not representative of operating performance in
accordance with generally accepted accounting principles ("GAAP"), they have
been provided to highlight the significant non-recurring elements contained
within the GAAP earnings per share calculation. Earnings per common share
totaled $0.71 in the first nine months of 1997. The earnings per common share
calculations reflect preferred dividend requirements of $706,000 in the first
nine months of 1996 and none in 1997.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  Revenues for 1996 were $68,482,000, an increase of $10,417,000, or 17.9%,
over 1995. On April 26, 1996, Alliance acquired all of the outstanding shares
of Royal Medical Health Services, Inc. ("Royal") and certain related assets.
Excluding revenues of $2,895,000 from operations which were sold in the second
half of 1995, the increase in revenues was $13,312,000, or 24.1%, with Royal
accounting for $4,694,000, or 8.5% of the increase. This increase reflects a
scan-based MRI revenues increase of $10,897,000, or 22.0%, ($4,532,000, or
9.2%, as a result of the Royal acquisition), resulting from a 23.4% increase
in total scan volume partially offset by a 1.1% decrease in the average
revenues realized per MRI scan. Royal accounted for 9.8% of the scan volume
increase and 0.1% of the offsetting price per scan decrease. The average
number of scans per day for each MRI system increased 15.5% to 6.7 in 1996
from 5.8 in 1995. Management attributes the non-Royal volume increase to
Alliance's continuing MRI systems upgrade program, which has enabled Alliance
to obtain new long-term contracts from both existing and new customers, and to
the effect of some smaller acquisitions. Management believes the decrease in
average revenues realized per scan is the result of: continuing competitive
pressure in the MRI service industry and cost containment efforts by health
care payors; obtaining contracts with customers that have high scan volumes
which justify lower scan prices; and many customers achieving discount price
levels on incremental scan volumes. Revenues under fixed fee contracts
increased $893,000, or 43.8%, resulting from an increased number of MRI
systems under such arrangements. Other revenues increased $891,000 primarily
as
 
                                      87
<PAGE>
 
a result of Alliance selling its investment in London-based Alliance Medical,
Ltd. and recording a gain of $750,000. CT revenues increased $632,000, or
21.8%, primarily as a result of the third quarter 1995 and fourth quarter 1996
acquisitions of two CT businesses.
 
  Alliance operated 86 MRI systems at December 31, 1996 compared to 76 MRI
systems at December 31, 1995. The average number of MRI systems operated by
Alliance was 85 during 1996, compared to 74 during 1995.
 
  Operating expenses, excluding depreciation, totaled $32,344,000 in 1996, an
increase of $4,002,000, or 14.1%, from 1995. Excluding expenses of $1,008,000
related to operations which were sold in the second half of 1995, the increase
in operating expenses was $5,010,000, or 18.3%, with Royal contributing
$2,333,000, or 8.5% of the increase. Payroll and related employee expenses
increased $1,789,000, or 15.0%, which was in line with the revenue increase.
Equipment rental expense increased $898,000, or 60.4%. The increase resulted
from higher number of rented MRI systems in operation and Alliance's leasing
of 20 new tractors in 1996. Other operating expenses increased $751,000, which
was offset by a $761,000 decrease in preventive maintenance contract and
cryogen expense, primarily as a result of more efficient systems and lower
contract rates associated with Alliance's equipment upgrade program.
 
  Depreciation expense during 1996 totaled $12,737,000, an increase of
$535,000, or 4.4%. Excluding depreciation expense of $638,000 related to
operations which were sold in the second half of 1995, depreciation expense
increased $1,173,000, or 10.1%, from the 1995 level principally due to a
higher amount of depreciable assets associated with equipment additions and
upgrades and the Royal acquisition. Amortization expense in 1996 increased
$607,000, or 45.1%, over the 1995 period as a result of the Royal acquisition
and four smaller acquisitions in late 1995 and 1996.
 
  Selling, general and administrative expenses totaled $8,130,000 in 1996, an
increase of $1,836,000, or 29.2%, from 1995. Excluding expenses of $369,000
related to operations sold in the second half of 1995, selling, general and
administrative expenses increased $2,205,000, or 37.2%. Payroll and related
expenses increased $1,457,000, primarily as a result of increased employee
compensation related to increased sales commissions, performance compensation
in connection with the increase in net income, early achievement of long term
incentive plan objectives and increased staffing levels. Bad debt expense
increase $567,000 in 1996 compared to 1995.
 
  Interest expense of $5,758,000 in 1996 was $705,000, or 14.0%, higher than
1995, primarily as a result of higher average outstanding debt balances during
1996 as compared to 1995. This increase related to debt assumed in connection
with the Royal acquisition and additional borrowing related to equipment
additions.
 
  An income tax provision of $1,060,000 was recorded in 1996. Alliance's pre-
tax income in 1996 was substantially offset by net operating loss
carryforwards; however, certain federal alternative minimum taxes and state
tax liabilities applied to this income, giving rise to the tax provision
recorded. In 1995, an income tax provision of $727,000 was recorded, also
related to certain federal alternative minimum taxes and state tax
liabilities. Alliance's 1996 effective tax rate of approximately 14% of pre-
tax income before extraordinary gains was comparable to the 1995 rate. At
December 31, 1996, Alliance had approximately $26,400,000 of net operating
loss carryovers available for federal regular income tax purposes to offset
future taxable income, subject to certain limitations. Approximately
$4,500,000 of this amount is not subject to such limitations; consequently,
approximately $6,700,000 of operating loss carryovers is available in 1997 for
regular federal income tax purposes. Alliance expects its future effective tax
rate to increase as these net operating loss carryovers are fully utilized.
 
  Alliance's net income before extraordinary gains was $6,501,000 in 1996
compared to net income of $4,102,000 in 1995, an increase of $2,399,000, or
58.5%, primarily attributable to the increase in revenues achieved without a
proportionate increase in operating and selling, general and administrative
expenses. Alliance reported extraordinary gains, net of income taxes, in the
fourth quarter of 1996 of approximately $6,300,000 on early extinguishment of
debt.
 
  Earnings per common share directly related to operations (excluding gains on
sales of assets) totaled $0.43 in 1996, compared to $0.26 for 1995, an
increase of 65.4%. Earnings per common share in 1996 also included $0.05
related to Alliance's fourth quarter sale of its investment in Alliance
Medical, Ltd. Alliance reported
 
                                      88
<PAGE>
 
extraordinary gains, net of income taxes, in the fourth quarter of 1996 of
approximately $6,300,000, or $0.55 per common share, on early extinguishment
of debt. In addition, Alliance recorded earnings of $0.15 per common share
related to the excess of the carrying amount of the Series A 6% cumulative
preferred stock repurchased over the consideration paid and other charges.
Although the preceding earnings per share amounts for 1996 are not
representative of operating performance in accordance with GAAP, they have
been provided to highlight the significant non-recurring elements contained
within the GAAP earnings per share calculation. Earnings per common share
totaled $1.18 in 1996. The earnings per common share calculations reflect
preferred dividend requirements of $943,000 in 1996 and $930,000 for 1995.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
  Revenues for 1995 were $58,065,000, an increase of $190,000, or 0.3%, over
1994. This increase reflects a $1,557,000 increase in MRI revenues under fixed
fee contracts and an increase in CT and other revenues totaling $125,000,
offset by a $1,492,000, or 2.9%, decrease in scan-based MRI revenues. The
decrease in scan-based MRI revenues resulted from a 5.8% increase in scan
volume offset by an 8.2% decrease in average revenues realized per MRI scan.
Management attributes the volume increases to Alliance's continuing MRI
systems upgrade program, which has enabled Alliance to obtain new long-term
contracts from both existing and new customers. The average number of scans
per day for each MRI system remained unchanged at 5.8. Management believes the
decrease in average revenues realized per scan is the result of continuing
competitive pressure in the MRI service industry and cost containment efforts
by health care payors, as well as obtaining contracts with customers that have
high scan volumes which justify lower scan prices on incremental scan volume.
The increase in MRI revenues under fixed fee contracts is a result of a higher
number of systems deployed in full-time temporary assignments, including
several older systems awaiting trade-in on new equipment. CT and other
revenues increases are generally associated with the acquisition of a mobile
CT business and the gain on sale of equipment and a related service contract,
offset by lower other imaging revenue resulting from the disposition of
Alliance's full-service imaging center in Fresno, California as of September
30, 1995. Alliance operated 76 MRI systems at December 31, 1995, compared to
72 systems at December 31, 1994. The average number of MRI systems operated by
Alliance was 74 in 1995, compared with 73 during 1994.
 
  Operating expenses, excluding depreciation, totaled $28,342,000 in 1995, a
decrease of $2,751,000, or 8.8%, from 1994. Payroll and related employee
expenses decreased $336,000, or 2.7%, to $12,153,000 due to more efficient
staffing associated with cost reduction efforts and a larger number of systems
staffed by customer personnel in 1995. Maintenance and cryogen contract
expense declined $288,000, or 3.1%, to $9,079,000, as a result of an increased
number of newer, efficiently-operating systems in the fleet in 1995 and lower
contract rates, partially offset by an increased number of systems. Equipment
rental expense decreased $828,000, or 33.9%, to $1,618,000, as operating
leases expired and Alliance returned the related equipment to the lessor. The
leased equipment was generally replaced with low cost used MRI systems
purchased by Alliance. Professional medical services, supplies, site fees and
repairs expenses collectively decreased $1,443,000 or 40.0%, to $2,805,000,
primarily as a result of reduced physician staffing and other cost control
efforts at Alliance's full-service imaging center in Fresno, California, which
was disposed of effective September 30, 1995.
 
  Depreciation expense during 1995 decreased $1,222,000, or 9.1%, from the
1994 level due to a lower amount of depreciable assets, resulting from
equipment write-downs in late 1994, partially offset by equipment additions in
1995. Amortization expense in 1995 increased $402,000, or 42.6%, over 1994
because of the revision of the amortization period for goodwill from 40 to 25
years, effective October 1, 1994, and a small business acquisition in 1995.
 
  Selling, general and administrative expenses were essentially unchanged from
the prior year. Payroll and related employee expenses increased $629,000, or
15.7%, as a result of long-term deferred incentive compensation costs and
inflationary pressures. Bad debt expense decreased $609,000, or 100.0%, to
zero in 1995 as a result of revised billing practices and continuing intensive
collection efforts, primarily with respect to Alliance's retail accounts
receivable.
 
  Interest expense of $5,053,000 in 1995 was $5,705,000, or 53.0%, lower than
in 1994 primarily as a result of Alliance's comprehensive debt restructuring,
effective as of December 31, 1994, and lower average outstanding debt balances
in 1995.
 
                                      89

  Alliance recorded special charges totaling $13,339,000 in the fourth quarter
of 1994. No such charges were incurred in 1995. Including these charges, the
loss before taxes totaled ($17,966,000) in 1994, compared to income before
taxes of $4,829,000 in 1995, an improvement of $22,795,000. Although the
preceding amounts before taxes are not representative of operating performance
in accordance with GAAP, they have been provided to highlight the significant
non-recurring element contained within the GAAP net income measurement. This
improvement resulted from significantly reduced operating expenses (including
depreciation), substantially lower interest expense and the absence of special
charges in 1995. Income before taxes in 1995 increased $9,456,000 over 1994's
loss before taxes without the effects of special charges.
 
  An income tax provision of $727,000 was recorded in 1995. Alliance's pre-tax
income in 1995 was substantially offset by net operating loss carryforwards;
however, certain federal alternative minimum taxes and state tax liabilities
applied to this income, giving rise to the tax provision recorded. In 1994, an
income tax provision of $1,100,000 was recorded as a result of federal
alternative minimum tax and certain state income taxes related to cancellation
of debt income for tax purposes associated with Alliance's financial
restructuring, as well as increased valuation allowances for deferred tax
assets. However, these reserved tax assets may be available to reduce future
income tax provisions. At December 31, 1995, Alliance had approximately
$33,000,000 in federal net operating loss carryforwards available to offset
future taxable income, subject to certain limitations.
 
  Alliance's net income was $4,102,000 in 1995, compared to a net loss of
($19,066,000) in 1994, an increase of $23,168,000, primarily attributable to
the increased operating profits, lower interest expense and absence of special
charges in 1995, as explained above. Net income in 1995 increased $9,354,000
over the net loss in 1994 without the effect of the special charges and
related tax impact. Although the preceding amount of net loss excludes the
effects of special charges and income taxes is not representative of operating
performance in accordance with GAAP, it has been provided to highlight the
significant non-recurring element contained within the GAAP net loss
measurement. This increase is attributable to higher operating profit and
lower interest expense in 1995.
 
  Earnings per common share totaled $0.28 in 1995, compared to a loss per
common share of ($2.68) in 1994 (which includes ($1.94) net loss per common
share for special charges). Although the preceding earnings per share amount
for 1994 is not representative of operating performance in accordance with
GAAP, it has been provided to highlight the significant non-recurring element
contained within the GAAP earnings per share calculation. The 1995 earnings
per common share calculation reflects preferred dividend requirements totaling
$930,000 which arose as part of Alliance's financial restructuring, effective
December 31, 1994. There were no preferred dividend requirements in 1994.
 
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Alliance generated $12.8 million, $18.0 million and $21.7 million from
operating activities in 1994, 1995 and 1996, respectively, and $17.3 million
and $22.1 million in the first nine months of 1996 and 1997, respectively. The
increase in cash provided by operating activities reflects the increase in
scan volumes and improved operating performance. Capital expenditures,
consisting primarily of new equipment purchases, totaled $22.4 million, $11.4
million and $34.4 million in 1994, 1995 and 1996, respectively, and $34.2
million in the first nine months of 1997. Since January 1, 1995, Alliance has
upgraded 23 MRI systems and purchased 35 new MRI systems, including
replacement systems. As of December 31, 1996, Alliance had binding equipment
purchase commitments totalling approximately $29.2 million. Alliance expects
to purchase the equipment under these commitments in 1997 and finance such
purchases with installment debt primarily provided by the equipment
manufacturers.
 
  The Company's primary cash needs consist of capital expenditures and debt
service. The Company incurs capital expenditures for the purposes of (i)
providing routine upgrades of its MRI systems; (ii) replacing or making major
upgrades to older, less advanced systems with new state-of-the-art systems;
and (iii) purchasing
 
                                      90
<PAGE>
 
new systems. The Company estimates that routine annual upgrade expenditures
average approximately $25,000 per system or approximately $2.4 million in the
aggregate, based on the fleet size at September 30, 1997. In addition to these
routine expenditures, the Company expects capital expenditures to be
approximately $12 million in the last three months of 1997 which reflects the
anticipated purchase of eight new MRI systems, including replacement systems.
The Company expects capital expenditures to be approximately $20 million in
1998, which includes the anticipated purchase of 10 new MRI systems and
routine upgrade expenditures. The Company's decision to purchase a new system
is typically predicated on obtaining new or extending existing customer
contracts which serve as the basis of demand for the new system.
   
  After giving effect to the Transactions, the Company will be capitalized
with $165.0 million of Notes, a $125.0 million Credit Agreement consisting of
a $50.0 million Term Loan Facility and a $75.0 million Revolving Loan
Facility, $6.9 million of other obligations and $15.0 million of Series F
Preferred Stock. The Notes will bear interest, payable semiannually, and will
require no principal repayments until maturity. The Term Loan will mature on
the sixth anniversary of the initial borrowing and will require annual
principal repayments of $0.5 million per year during the first five years and
$47.5 million in the sixth year. The Revolving Loan Facility will mature on
the fifth anniversary of the initial borrowing and will have mandatory
commitment reductions of $37.5 million on the fourth and fifth anniversaries
of the initial borrowing. The interest rate under the Credit Agreement is
expected to be based on LIBOR. The Credit Agreement will contain restrictive
covenants which, among other things, limit the incurrence of additional
indebtedness, dividends, transactions with affiliates, asset sales,
acquisitions, mergers and consolidations, liens and encumbrances, and
prepayments of other indebtedness. In addition, the Credit Agreement will
require loans to be prepaid with 100% of the net proceeds of non-ordinary-
course asset sales or other dispositions of property, issuances of debt
obligations and certain preferred stock and certain insurance proceeds, 75% of
annual excess cash flow and 50% of the net proceeds from common equity and
certain preferred stock issuances, in each case subject to limited exceptions.
Voluntary prepayments are permitted in whole or in part. See "Description of
the Credit Agreement". The Series F Preferred Stock will pay dividends at the
rate of 13.5% per annum, payable quarterly in arrears, with such dividends
payable in kind at the option of the Company for the first five years from the
issue date. The Series F Preferred Stock is mandatorily redeemable for its
liquidation preference plus accrued and unpaid dividends on the 10th
anniversary of the issue date. The Series F Preferred Stock is redeemable at
the option of the Company prior to the 10th anniversary at premiums (expressed
as a percentage of the accreted face value) declining over ten years from
13.5% to 0%. See "ALLIANCE CAPITAL STOCK--Series F Preferred Stock." The
Company does not currently intend to pay dividends in cash on the Series F
Preferred Stock prior to the fifth anniversary of the issue date and does not
currently intend to redeem the Series F Preferred Stock prior to the mandatory
redemption date.     
 
  The Company believes that after giving effect to the Transactions and the
incurrence of indebtedness related thereto, based on current levels of
operations and anticipated growth, its cash from operations, together with
other available sources of liquidity, including borrowings available under the
Revolving Loan Facility, will be sufficient over the next several years to
fund anticipated capital expenditures and make required payments of principal
and interest on its debt, including payments due on the Notes and obligations
under the Credit Agreement. In addition, the Company continually evaluates
potential acquisitions and expects to fund such acquisitions from its
available sources of liquidity, including borrowings under the Revolving Loan
Facility.
 
  The Company's expansion and acquisition strategy may require substantial
capital, and no assurance can be given that the Company will be able to raise
any necessary additional funds through bank financing or the issuance of
equity or debt securities on terms acceptable to the Company, if at all.

                                   INDUSTRY
 
  Diagnostic Imaging. Diagnostic imaging involves the use of non-surgical
techniques to generate representations of internal organs on film or video.
Diagnostic imaging systems have evolved from conventional x-rays to the
advanced technologies of MRI, CT, ultrasound, nuclear medicine, mammography,
positron emission tomography ("PET") and fluoroscopy. The market for
diagnostic imaging services in the United States is estimated to be in excess
of $50 billion annually, or 5% to 6% of total health care spending. MRI
services constituted approximately $6 to $7 billion of the diagnostic imaging
industry in 1996.
 
  Patients are typically billed for diagnostic imaging services by their
hospitals. The bill consists of a technical fee or charge for use of the
equipment as well as a professional fee for the services of the radiologist
who interprets the data. Hospitals which outsource diagnostic imaging
equipment and services pay providers directly and collect fees for service and
technical charges from payors.
 
  Magnetic Resonance Imaging. Magnetic resonance imaging involves the use of
high strength magnetic fields to produce computer-processed cross-sectional
images of the anatomy. MRI services are provided by hospitals with in-house
systems, independent fixed site operators and independent mobile operators.
The approximately 4,000 MRI systems in the United States include 2,400
hospital owned systems, 1,000 independent fixed site systems and approximately
600 mobile systems. The MRI industry has experienced rapid growth as a result
of increased physician acceptance of diagnostic imaging, substitution of MRI
for other imaging modalities (including x-ray based techniques), expanding
applications for MRI technology and health care reform which encourages
outpatient services. Total scan volumes have increased from 5.4 million in
1990 to 8.8 million in 1996. According to an industry consultant, scan volumes
are projected to grow at approximately 7% to 8% per year through 1999 and at
5% per year thereafter.
 
  The MRI services industry is highly fragmented. Recently, however, the
industry has begun to undergo consolidation. The Company believes such
consolidation is primarily the result of (i) economies of scale in the
provision of services to a larger customer base; (ii) cost-effective
purchasing of equipment, supplies and services by larger companies; and (iii)
the decision by many smaller, capital constrained operators to sell their MRI
businesses rather than make substantial investments in new imaging systems.
Despite the recent trend, management estimates that as of September 30, 1997,
the top eight MRI service providers operated only 13% of the total MRI systems
in the United States.
 
  The history of the MRI industry can be divided into three periods: (i)
initial growth from 1984-1992; (ii) downturn in 1993-1994; and (iii) renewed
growth and consolidation beginning in 1995-1996. The increased use of MRI as a
diagnostic tool between 1984 and 1992 resulted from a variety of factors
including falling equipment costs, increased physician acceptance of the
technology, increased number of clinical applications and Medicare reform
enacted by Congress in 1983, which encouraged outpatient treatment.
 
  Changes in the health care industry and legislative reform between 1992 and
1994 slowed the growth of the MRI industry. The threat of health care reform
and the desire to control medical costs and pricing, placed physicians under
tremendous scrutiny to control costs and further contributed to the decrease
in use of MRI by the medical profession. Simultaneously, the shift towards
health maintenance organizations and the trend to decrease utilization of
outpatient services and accept declining reimbursement rates (a 20% decline in
reimbursement rates was experienced between 1992-1994) led to a period in
which the use of MRI as a diagnostic tool was limited.
 
  Despite the new cost-conscious environment in which hospitals and physicians
operated, the advantages of MRI as compared to other forms of diagnostic
imaging, development of new practical uses of MRI and increased Medicare
reimbursement (1%-2% increase per year between 1994-1996) resulted in
increased MRI use beginning in 1995-1996. See "Business--Reimbursement."

  Imaging Systems and Technology. MRI technology dates back to 1971 when Dr.
Raymond Damadian began applying principles of magnetic resonance to the field
of diagnostic imaging. In 1984, the FDA approved the sale of MRI systems to
community hospitals and private clinics. A principal element underlying
magnetic resonance imaging is that atoms in various kinds of body tissue
behave differently in response to a magnetic field, enabling the
differentiation of internal organs and structures and normal and diseased
tissue. MRI facilitates the diagnosis of diseases and disorders at an early
state, often minimizing the cost and amount of care needed and frequently
eliminates the need for invasive diagnostic procedures. MRI is the preferred
imaging modality for the brain, the spine and other internal organs because it
produces a superior image of soft tissue, without artifacts from bony
structures that are sometimes apparent with x-ray based imaging techniques. In
addition, unlike x-rays and CT, MRI does not expose patients to ionizing
radiation. Applications for MRI include detection of brain lesions, such as
multiple sclerosis, tumors, strokes and infections, spinal injuries, diseases
and congenital disorders, and heart, chest, abdomen, ligament, tendon and
joint injuries or diseases.
 
  The major components of an MRI system are a large magnet, radio wave
equipment, and a computer for data storage and image processing. During an MRI
study, a patient lies on a table which is then placed into the magnet. The
patient spends approximately 15 to 45 minutes inside the magnet, depending
upon the type of MRI system and diagnostic study, during which time images of
multiple planes are acquired. Images obtained from an MRI examination are
displayed on a computer screen in the form of a cross-section of the organ or
tissue. This information can be stored on magnetic media for future access or
printed on film for interpretation by a physician and retention in the
patient's files.
 
  Depending upon type, features and options selected, an MRI system and
related housing and installation generally cost between $1.6 million and $2.2
million. The largest manufacturers of MRI systems are General Electric Medical
Systems, Siemens Medical Systems, Phillips N.V. and Picker International.
These manufacturers also supply maintenance and service under warranties and
contracts. Industry participants typically enter into contracts with the
manufacturers after the expiration of the warranty for comprehensive
maintenance programs on equipment to minimize downtime (the period of time
equipment is unavailable during scheduled use hours because of malfunctions).
 
  Research and Contrast Enhancement. Research is currently being conducted for
additional uses of MRI and the Company believes more applications for MRI may
be developed in the future. Contrast agents enhance the use of MRI in the
detection of neurological lesions, including specific types of brain tumors.
Contrast agents also enhance images of the post-operative spine, and are under
investigation for use in the liver and other organ systems. MRI's role in the
evaluation of cardiac disease and diseases of the bone marrow and joints is
also on the increase. New technological developments are expected to extend
the clinical uses of this technology and to increase the number of scans
performed by the Company's customers. In October 1995, Medicare began to
reimburse MRA procedures on a limited basis. MRA utilizes MRI technology to
view blood flow of the head and neck. Prior to October 1995, MRA procedures
were considered experimental and were not reimbursed by Medicare. Some MRA
procedures have been approved by Medicare; it is expected that additional MRA
procedures will be approved in the near future.
 
  Mobile MRI. Mobile MRI operators provide a cost-effective alternative
enabling hospitals to access MRI technology. Mobile MRI operators use
specially designed vans or trailers to transport MRI systems to hospitals and
provide trained technologists to perform the scans. Operators typically enter
into long-term contracts to provide a scheduled amount of service on a fee-
per-scan basis. Operators then design schedules for each system to rotate
among multiple hospitals in a manner that optimizes the utilization of each
system.
 
  Mobile MRI systems typically operate in non-metropolitan areas, targeting
small to mid-sized hospitals that do not own imaging systems. These hospitals
often cannot afford the significant capital investment associated with MRI
systems or lack the patient volume to utilize the systems in a cost-effective
manner. In addition, CON and other licensing requirements in many states have
further limited hospitals' ability to purchase MRI systems. However, such
hospitals need state-of-the-art diagnostic imaging technology to remain
competitive. In addition, many medical professionals have become increasingly
aware of the risks of medical malpractice suits and believe that such risks
would be reduced by utilizing state-of-the-art medical technology and related
services.

                                   BUSINESS
 
GENERAL
 
  The Company is a leading nationwide provider of diagnostic imaging services
and the largest operator of state-of-the-art mobile diagnostic imaging systems
and related outsourced radiology services in the United States. The Company
primarily provides MRI systems and services to hospitals and other health care
providers on a mobile, shared user basis. The Company also provides dedicated,
full-time MRI systems and services as well as full-service management of
imaging operations for selected hospitals. The Company's services enable small
to mid-size hospitals to gain access to advanced diagnostic imaging technology
and related value-added services without making a substantial investment in
equipment and personnel. The Company operates a fleet of 98 MRI systems and
services 356 MRI customers in 36 states under exclusive contracts with an
average remaining length of approximately 24 months as of September 30, 1997.
 
  Since the beginning of 1995, Alliance has substantially increased revenues
by adding new customers and increasing scan volumes at existing customer
sites. During the same period, the growth rate of Alliance's EBITDA and net
income has exceeded the growth rate of revenues principally as a result of
spreading costs (which are primarily fixed) over a larger revenue base and
implementing cost reduction and containment measures.
 
COMPETITIVE STRENGTHS
 
  The Company attributes its market leadership and its significant
opportunities for continued growth and increased profitability to the
following strengths:
 
  Largest Provider of Mobile MRI Services. The Company operates 98 MRI systems
in 36 states. The Company believes that the next largest mobile operator has a
fleet of approximately 70 MRI systems. Compared to its smaller competitors,
the Company believes it benefits from (i) significant equipment purchasing
savings; (ii) attractive service and maintenance contracts from its primary
equipment suppliers; (iii) strong name recognition and a reputation for
quality service; (iv) substantial financial flexibility and access to lower-
cost capital; and (v) the ability to efficiently deploy systems in a manner
which maximizes fleet utilization while satisfying customer requirements.
 
  Technologically Advanced MRI Fleet. The Company has invested approximately
$78 million since January 1, 1995 to replace and upgrade existing systems and
to purchase new systems. As a result, the Company believes that it has
upgraded substantially all of its systems and expects most of its capital
expenditures for at least the next three to five years to relate to new system
purchases. Of the Company's 98 MRI systems, 73 are state-of-the-art, high-
field 1.0 or 1.5 Tesla systems and 13 are state-of-the-art, mid-field 0.5
Tesla systems. The Company believes its fleet is among the newest and most
advanced in the industry, enabling the Company to perform a wider variety and
greater volume of scans and produce higher quality images, which the Company
believes provides a significant competitive advantage. Moreover, all of the
Company's state-of-the-art systems are designed to facilitate hardware and
software upgrades. As a result, the Company's systems should remain on the
leading edge of technological developments. In addition, while many of its
competitors lease their systems, the Company owns the vast majority of its
systems, generally providing greater flexibility and lower costs over the life
of the systems.
 
  Exclusive, Long-Term Contracts in Attractive Markets. The Company generates
substantially all of its revenues from exclusive, long-term contracts with
hospitals and other health care providers, with the price for its services
determined on a fee-per-scan basis. The Company has 20, 84 and 77 contracts
that will expire, if not renewed or extended, in the fourth quarter of 1997,
and the years 1998 and 1999, respectively. The Company anticipates that it
will renew or extend substantially all of these contracts. The Company's
contracts typically offer tiered pricing with lower fees on incremental scans,
allowing customers to benefit from increased scan volumes and the Company to
benefit from the operating leverage associated with increased scan volumes.
Accordingly, tiered pricing enables the Company to retain customers who may be
considering purchasing their own MRI systems rather than renewing a contract
with a mobile provider. As of September 30, 1997, the
 
                                      94
<PAGE>
 
Company had 356 MRI customers under exclusive contracts which averaged
approximately 24 months in remaining length. Most of the Company's contracts
are with hospitals that have fewer than 200 beds, many of which may lack the
financial resources or patient volume to justify the purchase of an MRI
system.
 
  Superior Customer Service and Strong Customer Relationships. The Company
positions itself as a service company rather than solely as an equipment
provider and competes on the basis of value-added services in addition to
price. The Company differentiates itself from competitors by aggressively
marketing its services to referring physicians, radiologists and hospital
administrators and by having the advanced imaging systems, trained
technologists, fleet management capabilities and fleet size to accommodate the
growing needs of its customers. Value-added services offered by the Company
include patient scheduling and pre-screening, insurance pre-authorization,
appointment confirmation, billing, managed care contracting, and management
reporting services. The Company often provides two technologists per mobile
system per shift and is therefore able to accommodate higher patient volume
and operate with greater efficiency, resulting in high customer satisfaction
levels. As a result, the Company enjoys strong customer relationships, having
added 146 net new MRI customers from January 1, 1995 through September 30,
1997 and renewed or extended 197 of its customer contracts in this period.
 
  Substantial Operating Leverage. Because of the significant amount of fixed
costs associated with operating an MRI system, MRI service providers benefit
from operating leverage, with increased utilization rates resulting in
significant increases in operating earnings and operating margins. The
Company's average scans per system per day increased to 7.2 for the nine
months ended September 30, 1997 from 6.7 for the nine months ended September
30, 1996.
 
  Favorable Payment Terms. Approximately 92% of the Company's billings are
direct to hospitals. The hospitals, in turn, generally pay the Company prior
to collecting from patients and third party payors. Accordingly, the Company's
exposure to uncollectible patient receivables is minimized. In addition,
management believes that the Company's average number of DSO of receivables,
which was 45 days as of September 30, 1997, is among the most favorable in the
mobile MRI industry and more favorable than the DSO of many health care
companies.
 
  Experienced Management Team. The Company's senior management team has an
average of nine years of industry experience and six years of experience with
Alliance. The Company's senior and operating managers have successfully
developed and implemented sophisticated marketing, fleet management and
financial strategies which have enabled the Company to become the largest and
among the most efficient and profitable mobile MRI operators. Upon
consummation of the Recapitalization and after giving effect to the Company's
option plans, management will own in excess of 11% of the capital stock of the
Company on a fully diluted basis.
 
BUSINESS STRATEGY
 
  The Company's management team has developed and implemented a business
strategy designed to maximize return on invested capital and in turn increase
revenues and cash flow. The Company's revenues for the nine months ended
September 30, 1997 increased to $62.3 million from $49.1 million for the nine
months ended September 30, 1996. In addition, the Company's income before
extraordinary gain for the nine months ended September 30, 1997 increased to
$6.8 million from $5.1 million for the nine months ended September 30, 1996.
The Company achieved comparable customer revenue growth of 25.9% and 8.8%,
respectively, in the first nine months of 1997 and in the year ended December
31, 1996. In addition, during the three months ended September 30, 1997, the
Company added a total of eight net mobile MRI systems. Management believes
that the recent financial performance of the Company does not yet fully
reflect the benefit of these new systems.
 
  The primary components of the Company's business strategy are to (i)
increase scan volumes; (ii) maximize return on invested capital; (iii) expand
the scope of services provided and (iv) pursue strategic acquisitions.
 
 
                                      95
<PAGE>
 
  Increase Scan Volumes. The Company believes that the demand for MRI
procedures will continue to grow as new applications are developed and MRI
continues to gain acceptance and replace other imaging modalities. The Company
has an opportunity to significantly increase its scan volumes by both adding
new customers and increasing scans performed for existing customers. In
response to the growing demand for MRI procedures, the Company added 26 net
MRI systems and 146 net new MRI customers from January 1, 1995 to September
30, 1997. The Company expects to add 14 net MRI systems by the end of 1998.
The Company's decision to purchase new systems is typically predicated on
obtaining new customer contracts which serve as the basis of demand for the
new MRI systems.
 
  Maximize Return on Invested Capital. The Company actively manages the
utilization of its MRI systems to maximize its return on invested capital
(i.e., the amount of cash flow generated by each system relative to the
carrying value of such system). In the nine months ended September 30, 1997,
the Company generated an annualized return on invested capital of 42.9%. The
Company typically upgrades the quality of its fleet in markets where demand is
greatest and redeploys less advanced systems in markets where demand is lower
in order to generate incremental cash flow. The Company estimates that, on
average, a system can be utilized in a high demand market for approximately
eight years when properly maintained and upgraded, after which time the system
can either be utilized in a market with less demand or traded in for a new
system.
 
  Expand the Scope of Services Provided. The Company intends to leverage its
national presence and customer service capabilities by introducing new
services, the demand for which management believes will increase as hospitals
continue to outsource departments and cost centers and seek incremental
revenue sources. The Company expects to expand into open MRI services,
lithotripsy services (which involves the utilization of sound waves to
eliminate kidney stones and urinary calculus in the bladder) and full-service
management of hospital radiology departments. Open MRI systems are used on
claustrophobic patients and patients whose size prohibits them from entering
traditional MRI systems. Management believes that with the introduction of its
first open MRI system in the fourth quarter of 1997, the Company will be the
first operator to offer mobile open MRI service.
 
  Pursue Strategic Acquisitions. Management has designed an acquisition
strategy for the Company which capitalizes on the consolidation occurring in
the industry as well as the Company's ability to (i) access substantial and
lower cost financial resources; (ii) realize significant synergies, operating
expense reductions and overhead cost savings; (iii) apply its consolidation
strategy to expand outside of diagnostic imaging in related services; (iv)
utilize the Company's expertise in logistics and fleet management; and (v)
leverage the Company's existing customer relationships to expand into new
modalities.
 
  On October 20, 1997, Alliance announced the execution of a definitive
agreement to acquire MCIC, a Cleveland, Ohio based provider of mobile MRI
services, CT services and other outsourced healthcare services. The
acquisition also includes MCIC's one-half interest in an operating joint
venture in Michigan. The purchase price consists of $13 million cash plus the
assumption of approximately $5 million in financing arrangements. MCIC
operates 14 mobile MRI systems and several other diagnostic imaging systems,
primarily in Ohio, Michigan, Indiana and Pennsylvania. The transaction was
completed on November 21, 1997. In addition, the Company is currently engaged
in acquisition discussions with several other MRI service providers.
Management believes future acquisitions will enable the Company to redeploy
systems in overlapping markets, resulting in higher utilization rates and the
opportunity to increase penetration in other markets.
 
OPERATIONS
 
  Customer Base. The Company believes that many hospitals and other health
care providers require access to MRI services to remain competitive in the
health care marketplace. Regulatory and licensing requirements in many states
may also limit access to MRI systems. In addition, many health care providers
lack sufficient patient volume or financial resources to justify the purchase
of an MRI system. Such providers contract for mobile, shared-user systems or
single-user, full-time systems to gain access to MRI technology and to provide
comprehensive MRI services to their patients. In addition, many health care
providers, regardless of whether their patient utilization levels and
financial resources justify the purchase of an MRI system, prefer to contract
with
 
                                      96
<PAGE>
 
the Company for full-time or shared-user imaging systems to (i) obtain the use
of an MRI system without any capital investment or financial risk; (ii) retain
the ability to switch system types and avoid technological risk; (iii) obtain
MRI services in jurisdictions in which the use of the Company's services
facilitates the procurement of regulatory approvals; (iv) avoid future
uncertainty as to reimbursement policies; (v) eliminate the need to recruit,
train and manage qualified technologists; (vi) outsource their entire MRI
service to obtain access to needed technology while avoiding financial
investment or risk and obtaining management expertise; or (vii) provide
additional imaging services when patient demand exceeds their in-house
capability.
 
  The Company's MRI and CT services, which include imaging systems,
technologists and support services, are provided on both a mobile, shared-user
basis and on a full-time basis to single customers. As of September 30, 1997,
the Company provided imaging systems and related technologists and support
services to 389 customers (356 for MRI services and 60 for CT services; some
customers contract for both modalities) consisting primarily of small to mid-
sized hospitals (i.e., hospitals with 50-200 beds). The Company believes that
many of such hospitals lack the patient volume or financial resources to
justify the purchase of an MRI system. As of September 30, 1997, the Company
provided services and equipment to customers in 36 states.
 
  Typically, the Company's MRI systems are contracted on average for five to
six days a week. The Company believes that as customers become familiar with
the basic or expanded technology and its applications, the corresponding MRI
system's rate of usage generally increases, causing the number of scans per
day to increase and eventually leading to requests for additional days of
usage.
 
  Contract Terms. Contract fees are charged on a fee-per-scan, fee-per-day or
fee-per-month basis (with numerous variations within each billing method to
accommodate particular customers' needs). Generally, the Company provides
technologists under contracts billed on a fee-per-scan or fee-per-day basis
but not under contracts billed on a fee-per-month basis. Although a typical
contract offers daily flat-rate options, most customers currently pay on a
fee-per-scan basis. The amount of fees paid on this basis depends upon the
type of imaging system provided, the term of the contract, the types and
number of scans performed as well as the day of the week on which scans are
performed. The contracts typically allow the Company to reduce the number of
days of service provided based upon the customer's scan volume, or to
terminate the contract if the Company is unable to realize a profit on the
services provided. The Company typically enters into exclusive, one to eight
year contracts that include automatic renewal provisions. In addition, the
Company's marketing representatives consistently seek to renew and extend
contracts prior to expiration. From January 1, 1995 through September 30,
1997, the Company renewed or extended 197 of its customer contracts. As of
September 30, 1997, the Company's contracts averaged approximately 24 months
in remaining length.
 
  Imaging Systems. At September 30, 1997, the Company operated 98 MRI systems
and 14 CT systems. Of the 98 MRI systems, 73 are state-of-the-art, high-field
1.0 or 1.5 Tesla systems and 13 are state-of-the-art, mid-field 0.5 Tesla
systems. These systems are designed to facilitate hardware and software
upgrades. As a result, the Company's systems should remain at the leading edge
of technological developments. Further, of the 98 MRI systems, 86 are housed
in mobile coaches and 12 are housed in relocatable modular buildings on
hospital campuses or installed in the hospital facility. Substantially all of
the imaging systems are owned by the Company. One of such systems is a fixed-
site system at a large hospital in Georgia operated by a partnership of which
a subsidiary of the Company is a partner.
 
  The Company orders substantially all of its imaging systems from major
medical device manufacturers, primarily General Electric Medical Systems,
Siemens Medical Systems and Picker International. Generally, the Company
orders its imaging systems from such major manufacturers while simultaneously
contracting with health care providers for their use, thereby reducing the
Company's system utilization risk. The Company's MRI systems are installed in
specially-designed trailers or relocatable, modular buildings. The trailers
and relocatable modular buildings are designed jointly by the imaging system
manufacturer and the housing manufacturer and are designed to provide image
quality identical to those installed in hospital facilities.
 
 
                                      97
<PAGE>
 
  Fleet Management. The Company seeks to maximize cash flow and return on
assets by actively managing its fleet to maximize utilization. The Company
employs logistics management systems and redeploys or trades in older MRI
systems when it purchases new MRI systems. MRI systems are currently scheduled
for as little as one-half day and up to seven days per week at any particular
facility. Generally, technologists and a driver are assigned to each of the
mobile operating systems. Movement of the systems typically occurs at night
via a fleet of Company-owned or leased tractors. The drivers move the systems
and activate them upon arrival at each imaging site so that the systems are
operational when the Company's technologists arrive on the following scheduled
imaging day.
 
  Regional Management. The Company's seven regional offices market, manage and
staff the operation of its imaging systems. The Company's regional offices are
located in Anaheim and Roseville, California; Pittsburgh, Pennsylvania;
Chicago, Illinois; Colorado Springs, Colorado; Burlington, Connecticut; and
Macon, Georgia. Each region has individuals responsible for sales and
operations management.
 
  Licensing and JCAHO Accreditation. Most states do not currently license MRI
providers such as the Company, although many do subject such providers to CON
requirements. Hospitals with which the Company has contracted are subject to a
variety of regulations and standards of state licensing and other authorities
and accrediting bodies such as the Joint Commission on Accreditation of
Healthcare Organizations ("JCAHO"). As an outside vendor, the Company may be
required to comply with such regulations and standards to enable the hospitals
with which it has contracted to maintain their permits, approvals and
accreditation. Alliance is in the process of seeking accreditation from JCAHO.
 
CUSTOMER SUPPORT
 
  As part of its full service package, the Company provides several levels of
support to a hospital or health care provider. The Company's technologists who
staff the MRI systems regularly work with the hospital radiologists, referring
physicians and nursing staff to perform the scans. The technologists also work
with regional technical advisors who are specialists in MRI technology and
consult on specialized technical problems, hold periodic training sessions for
the technologists, radiologists, referring physicians and health care
customers and provide problem-solving services. These specialists play a
central role in the Company's retention of accounts and building of scan
volumes. Management believes that targeted direct marketing at each hospital
with assigned responsibility for support services is a key element for
broadening the awareness of MRI technology, building scan volumes and
obtaining contract renewals.
 
SALES AND MARKETING
 
  Currently, the Company's sales force consists of 13 members who identify and
contact candidates for the Company's services each with the overall management
and sales responsibility for a specific region of the country. Direct
marketing plays a primary role in the Company's development of new customers.
The Company employs 18 full-and part-time marketing representatives who
develop scan volumes at existing and new customer locations by introducing the
Company's services to referring physicians and keeping such physicians
apprised of the Company's MRI service capabilities. In addition, certain of
the Company's executive officers and regional vice presidents spend a portion
of their time marketing the Company's services. The Company believes that
having senior managers involved in sales and contract negotiations enhances
its ability to obtain new and retain existing customers.
 
MAINTENANCE
 
  For its MRI and CT systems, the Company primarily relies upon the
manufacturer to provide maintenance and service under warranties and service
contracts. These service contracts require the Company to pay fixed monthly
fees or variable fees on a risk-sharing basis.
 
  Timely, effective service is essential to maintaining high utilization rates
on the Company's MRI systems. If the Company experiences greater than
anticipated malfunctions of its equipment or if it is unable to promptly
obtain the service necessary to keep its systems functioning effectively, its
business could be adversely affected.
 
                                      98
<PAGE>
 
  The Company contracts with the MRI equipment manufacturers for comprehensive
maintenance programs on its systems to minimize downtime (the period of time
equipment is unavailable during scheduled use hours because of malfunctions).
These maintenance contracts commence upon the expiration of the applicable
warranty period. The systems are generally warranted by the systems
manufacturer for a specified period of time, usually one year to eighteen
months from the date of purchase. During the warranty period and maintenance
contract term, the Company receives uptime guarantees (a guarantee that
equipment will function for a specified percentage of scheduled use hours.)
However, these guarantees are not expected to substantially compensate the
Company for loss of revenue for downtime.
 
REIMBURSEMENT
 
  Substantially all the Company's revenues are derived directly from health
care providers rather than from private insurers, other third party payors or
governmental entities. Consequently, the Company historically has not had
material direct exposure to, or direct connection with, patient billing,
collections or reimbursement by insurance companies, other third parties or
Medicare. However, to a lesser extent, the Company's revenues are generated
from direct billings to patients or their third party payors which are
recorded net of contractual discounts and other arrangements for providing
services at less than established patient billing rates. Net revenues from
direct patient billing amounted to approximately 8% of the Company's revenue
in 1996.
 
  Most private health care insurers, including various Blue Cross and Blue
Shield Plans, reimburse approximately 70% to 100% of the health care
provider's charge for MRI and CT scans. Such insurers may impose limits on
reimbursement for imaging services or deny reimbursement for tests that do not
follow recommended diagnostic procedures. Because patient reimbursement may
indirectly affect the levels of fees the Company can charge its customers by
constricting the health care providers' profit margin, widespread application
of restricted or denied reimbursement schedules could adversely affect the
Company's business. Conversely, at lower reimbursement rates, a health care
provider might find it financially unattractive to own an MRI or CT system,
but could benefit from purchasing the Company's services.
 
  Congress has attempted to restrict rising federal reimbursement costs under
the Medicare program by setting predetermined payment amounts for
reimbursement of inpatient services according to each patient's diagnosis
related group ("DRG"). Because a DRG rate compensates a hospital for all
services rendered to a patient, a hospital cannot be separately reimbursed by
Medicare for an MRI scan or other procedure performed on an inpatient. DRG
payment rates for inpatient services became effective in the early 1980's and
have been adjusted downward since then. Currently, those payment rates are not
applicable to outpatient services; instead, Medicare reimbursement for imaging
services furnished in a hospital outpatient setting is subject to alternative,
generally more favorable, payment limits tied to the physician fee schedule
described below. However, it is possible that DRG payment rates or other
limits might be implemented with respect to outpatient services in the future.
 
  Because payments have generally been less restricted in non-hospital
outpatient settings, in prior years there has been rapid growth in MRI systems
at non-hospital free-standing facilities which provide outpatient services.
HHS, as required by statute, has issued fee schedules for reimbursing
physicians who treat Medicare patients. Under these fee schedules, physician
reimbursement for professional services is based on a set of values assigned
to each service provided by a physician. The fee schedules also generally
apply to reimbursement for technical services (such as those provided by the
Company) except in limited circumstances. There can be no assurance that
Medicare payments will remain comparable to present levels. In particular, on
June 18, 1997, the Health Care Financing Administration ("HCFA") issued a
proposed rule affecting, among other things, the practice expense component of
the physician fee schedule, physician supervision requirements for certain
diagnostic tests and the adoption of a new definition of an independent
diagnostic testing facility. Under the proposed rule, the Relative Value Units
("RVU") for MRI scans would be relatively unchanged, but the RVUs for MRI
scans with contrast would be reduced significantly. The proposed effective
date of the rule is January 1, 1998. However, as part of federal budget
legislation recently signed into law, implementation of the practice expense
changes will be delayed until January 1, 1999, with a three year transition
period for implementing the new
 
                                      99
<PAGE>
 
method for calculating practice expenses. While the impact of the proposed
changes is dependent on numerous factors, including whether the proposed rule
is adopted substantially in the proposed form and whether the Company's
hospital customers will seek similar adjustments in payments to the Company
for scans with contrast agents to the extent they are currently charged
additional amounts for contrast exams, there can be no assurance that such
practice expense changes will not, directly or indirectly, have a material
adverse effect on the Company's business or results of operations.
 
  The Budget Reconciliation Act for 1998 that was recently signed into law
contains a number of changes to the Medicare program which will adversely
affect hospitals and which could therefore potentially have an impact on
suppliers of goods and services to hospitals, including the Company. In
particular, among other things, the Act requires implementation of a
prospective payment system for outpatient services beginning in 1999; and
reduces hospital inpatient reimbursement for both operating and capital
expenses compared with reimbursement levels that would have prevailed absent
any change in law. The Company believes that approximately 15% to 20% of its
hospital customers' MRI revenues are derived from Medicare patients.
 
REGULATION
 
  Many aspects of the health care industry in the United States, including the
Company's business, are subject to extensive federal and state government
regulation. Although the Company believes that its operations comply with
applicable regulations, there can be no assurance that subsequent adoption of
laws or interpretations of existing laws will not regulate, restrict or
otherwise adversely affect the Company's business.
 
  The marketing and operation of the Company's MRI and CT systems are subject
to state laws prohibiting the practice of medicine by non-physicians and the
rebate or division of fees between physicians and non-physicians. Management
believes that its operations do not involve the practice of medicine because
all professional medical services relating to its operations, such as the
interpretation of the scans and related diagnoses, are separately provided by
licensed physicians not employed by the Company. Further, the Company believes
that its operations do not violate state laws with respect to the rebate or
division of fees.
 
  The Company is subject to federal and state laws which govern financial and
other arrangements between health care providers. These include the federal
Medicare and Medicaid anti-kickback statutes which prohibit bribes, kickbacks,
rebates and any other direct or indirect remuneration in return for or to
induce the referral of an individual to a person for the furnishing, directing
or arranging of services, items or equipment for which payment may be made in
whole or in part under the Medicare, Medicaid or other federal health care
programs. Violation of the anti-kickback statute may result in criminal
penalties and exclusion from the Medicare and other federal health care
programs. Many states have enacted similar statutes which are not necessarily
limited to items and services paid for under the Medicare or a federally
funded health care program. In recent years, there has been increasing
scrutiny by law enforcement authorities, HHS, the courts and Congress of
financial arrangements between health care providers and potential sources of
patient and similar referrals of business to ensure that such arrangements are
not designed as mechanisms to pay for patient referrals. HHS interprets the
anti-kickback statute broadly to apply to distributions of partnership and
corporate profits to investors who refer federal health care program patients
to a corporation or partnership in which they have an ownership interest and
to payments for service contracts and equipment leases that are designed to
provide direct or indirect remuneration for patient referrals or similar
opportunities to furnish reimbursable items or services. In July 1991, HHS
issued "safe harbor" regulations that set forth certain provisions which, if
met, will assure that health care providers and other parties who refer
patients or other business opportunities, or who provide reimbursable items or
services, will be deemed not to violate the anti-kickback statute. The Company
is also subject to separate laws governing the submission of false claims. The
Company is a party to a partnership for the provision of MRI services. The
Company believes that the partnership is in compliance with the anti-kickback
statute. The Company believes that its other operations likewise comply with
the anti-kickback statutes.
 
  A federal law, commonly known as the "Stark Law," also imposes civil
penalties and exclusions for referrals for "designated health services" by
physicians to certain entities with which they have a financial
 
                                      100
<PAGE>
 
relationship subject to certain exceptions. "Designated health services"
include, among others, MRI services. While implementing regulations have been
issued relating to referrals for clinical laboratory services, no implementing
regulations have been issued regarding the other designated health services,
including MRI services. In addition, several states in which the Company
operates have enacted or are considering legislation that prohibits "physician
self-referral" arrangements or requires physicians to disclose any financial
interest they may have with a health care provider to their patients to whom
they recommend that provider. Possible sanctions for violating these
provisions include loss of licensure and civil and criminal sanctions. Such
state laws vary from state to state and seldom have been interpreted by the
courts or regulatory agencies. Nonetheless, strict enforcement of these
requirements is likely. The Company believes its operations comply with these
federal and state physician self-referral laws.
 
  In some states, a CON or similar regulatory approval is required prior to
the acquisition of high-cost capital items, including diagnostic imaging
systems or provision of diagnostic imaging services by the Company or its
customers. CON regulations may limit or preclude the Company from providing
diagnostic imaging services or systems. A significant increase in the number
of states regulating the Company's business within the CON or state licensure
framework could adversely affect the Company. Conversely, repeal of existing
CON regulations in jurisdictions where the Company has obtained or operates
under a CON could also adversely affect the Company. This is an area of
continuing legislative activity, and there can be no assurance that the
Company will not be subject to CON and licensing statutes in other states in
which it operates or may operate in the future.
 
LIABILITY INSURANCE
 
  While the Company's imaging systems are at a customer's facility, they
operate only under the direction of licensed physicians on the customer's
staff who direct the procedures, supervise the Company's technologists and
interpret the results of the examinations. Currently, there are no known
biological hazards associated with MRI. However, there is a risk of harm to a
patient who has a ferrous material or certain types of cardiac pacemakers
within his or her body. Patients are carefully screened to safeguard against
this risk. To protect against possible exposure for professional liability,
the Company maintains professional liability insurance.
 
COMPETITION
 
  The market for diagnostic imaging services and imaging systems is highly
competitive. In addition to direct competition from other mobile providers,
the Company competes with free-standing imaging centers and health care
providers that have their own diagnostic imaging systems and with equipment
manufacturers that sell or lease imaging systems to health care providers for
full-time installation. Some of the Company's direct competitors which provide
contract MRI services may have access to greater financial resources than the
Company. In addition, some of the Company's customers are capable of providing
the same services to their patients directly, subject only to their decision
to acquire a high-cost diagnostic imaging system, assume the associated
financial risk, employ the necessary technologists and satisfy applicable
licensure and CON requirements, if any. The Company competes against other MRI
service providers on the basis of quality of services, quality and magnetic
field strength of imaging systems, price, availability and reliability.
 
EMPLOYEES
 
  As of September 30, 1997, the Company had 501 employees, of whom
approximately 405 were trained diagnostic imaging technologists, patient
coordinators, technical support staff or other field operations personnel. Of
the Company's employees, 153 are employed on a part-time or "as needed" basis.
None of the Company's employees are represented by a labor organization and
the Company is not aware of any activity seeking such organization. The
Company considers its relations with its employees to be satisfactory.
 
 
                                      101
<PAGE>
 
PROPERTIES
 
  The Company leases approximately 15,000 square feet of space in an office
building in Anaheim, California for its executive and principal administrative
offices. This office will be expanded to a total of approximately 24,500
square feet during the fourth quarter of 1997. The Company also leases a
15,600 square foot operations warehouse in Orange, California, as well as
space for its other regional offices.
 
LEGAL PROCEEDINGS
 
  The Company from time to time is involved in routine litigation incidental
to the conduct of its business. The Company believes that no litigation

                          EXECUTIVE COMPENSATION PLAN
 
  Alliance compensates its executive officers using a plan that includes a
predetermined target level of annual cash compensation for each officer. The
plan is set by the Compensation Committee of Alliance's Board of Directors
(the "Compensation Committee") at the beginning of the fiscal year. The actual
total level of compensation for the fiscal year is determined after the end of
the fiscal year based on the level of achievement of various criteria. The
compensation plan establishes a minimum annual remuneration (i.e., base
salary), a maximum compensation level and a target compensation amount.
 
  The annual minimum, target and maximum compensation levels established for
Alliance's Named Executive Officers for 1996 is presented in the following
table, together with the total actual cash compensation earned.

</TABLE>
 
  The actual amounts of cash compensation to Mr. Zehner, Mr. Pino and Mr.
White, Alliance's Chief Executive Officer, Chief Operating Officer and Chief
Financial Officer, respectively, were determined by the Compensation Committee
based on its evaluation of the extent to which Alliance's 1996 earnings per
share and cash flow budgets and individual objectives applicable to each
executive were achieved. The actual amounts of cash compensation to executives
responsible for the Company's various operating regions were determined by the
Compensation Committee based on its evaluation of the extent to which regional
operating profit budgets and individual objectives applicable to each such
executive were achieved. These amounts were generally more than the target
amounts because Alliance significantly exceeded its earnings per share, cash
flow and regional operating budgets. A predetermined percentage of the
possible compensation award above the minimum amount is determined with
respect to each of the criteria mentioned above for the respective officers.

    reported by Nasdaq: $4.75--25%; $5.50--50%; $6.25--75%; $7.00--100%;
    subject to a maximum vesting of one-third per year from February 29, 1996
    regardless of stock price (no limits after year three). As of March 15,
    1997, Alliance's stock price had achieved the first three accelerated
    vesting hurdles, and the 1996 options were two-thirds vested at such date.

    based upon appreciation over a ten-year period from the $3.5625 exercise
    price of the options. The 5% and 10% assumed annual rates of appreciation
    would result in the price of the Alliance's common stock increasing to
    $5.80 and $9.24 per share, respectively.

             LONG-TERM INCENTIVE PLAN--AWARDS IN LAST FISCAL YEAR
 
  In addition to the annual plan described above under "--Executive
Compensation Plan," Alliance instituted a long-term executive incentive plan
("LTIP") in 1995 to provide future awards in cash or equivalent amounts of
Alliance common stock to key executives. The objective of the plan is to
advance the long-term interests of Alliance and its stockholders by providing
substantial incentives to meet or exceed certain cash flow goals necessary to
ensure that Alliance would be able to service its long-term obligations on a
continuing basis, and that it would be able to pay certain preferred stock
dividends in cash, thereby avoiding the substantial dilution to existing
common stockholders if such dividends were paid in common stock equivalents.
As of January 2, 1997, Alliance had retired all of its Series A 6% Redeemable
Preferred Stock (the "Series A Preferred Stock"), thereby fully satisfying the
second objective of the LTIP.
 
  The following awards under the plan were earned by the Named Executive
Officers in 1996:

(1) Under the LTIP, amounts may be accrued with respect to each of the fiscal
    years from 1995 to 1998 based upon two factors: (a) the extent to which
    Alliance's actual earnings before depreciation, amortization, interest,
    taxes and equipment charges (as more precisely defined in the LTIP,
    "EBDIT") exceeds targeted EBDIT for such year and (b) the extent to which
    Alliance pays dividends on its Series A Preferred Stock in cash for such
    year (thereby avoiding the potential dilution to holders of common stock
    from the payment of dividends in common stock equivalents). As noted
    above, Alliance retired all of the Series A Preferred Stock as of January
    2, 1997, thereby satisfying the Series A Preferred Stock dividend criteria
    of the LTIP. Therefore, the cumulative amount of the dividend component of
    the award was deemed earned and was accrued in fiscal 1996. Amounts
    accrued under the LTIP are allocated to specified senior officers. Amounts
    in the table reflect the potential pool amounts accrued in 1996 allocable
    to each of Alliance's Named Executive Officers based upon the two criteria
    summarized above as applied to fiscal 1996.

                            PRINCIPAL STOCKHOLDERS
 
  Immediately after the Recapitalization and giving effect to the New Option
Plan, Apollo will own approximately 84% of the outstanding shares of Alliance
Common Stock (approximately 74% on a fully diluted basis), BT will own
approximately 6% of the outstanding shares of Alliance Common Stock
(approximately 5% on a fully diluted basis) and management of Alliance will
own in excess of 11% of the shares of Alliance Common Stock on a fully diluted
basis. Following the consummation of the Recapitalization, and depending on
the number of stockholders remaining, Alliance anticipates that it may be
necessary and/or desirable to have Alliance's Common Stock, which is currently
traded on The Nasdaq SmallCap Market, delisted and deregistered from the
reporting requirements of the Exchange Act. See "RISK FACTORS--Possible
Delisting; Loss of Liquidity."
 
  The following table sets forth information regarding the beneficial
ownership of Alliance Common Stock as of November 7, 1997, for each person
known to the Company to beneficially own more than 5% of such stock, each
director and director nominee of the Company, each of the executive officers
and all executive officers and directors of the Company as a group. Unless
otherwise specified, the address of each such person is 1065 North

                     DESCRIPTION OF ALLIANCE CAPITAL STOCK
 
GENERAL
 
  Alliance is authorized by its Restated Certificate of Incorporation, as
amended, to issue an aggregate of 50,000,000 shares of Alliance Common Stock
and 1,000,000 shares of preferred stock. The following is a summary of certain
of the rights and privileges pertaining to the Alliance Common Stock. For a
full description of Alliance Common Stock, reference is made to Alliance's
Restated Certificate of Incorporation, as amended, a copy of which is filed as
an exhibit to the Registration Statement of which this Proxy
Statement/Prospectus forms a part.
 
VOTING RIGHTS
 
  The holders of the Alliance Common Stock are entitled to one vote per share
on all matters submitted for action by the stockholders. There is no provision
for cumulative voting with respect to the election of directors. Accordingly,
the holders of more than 50% of the shares of Alliance Common Stock can, if
they choose to do so, elect all of the directors. In such event, the holders
of the remaining shares will not be able to elect any directors.
 
DIVIDEND RIGHTS
 
  All shares of Alliance Common Stock are entitled to share in such dividends
as the Board of Directors may from time to time declare from sources legally
available therefor.
 
LIQUIDATION RIGHTS
 
  Upon liquidation or dissolution of Alliance, whether voluntary or
involuntary, all shares of Alliance Common Stock are entitled to share equally
in the assets available for distribution to stockholders after payment of all
prior obligations of Alliance.
 
AMENDED AND RESTATED CERTIFICATE OF INCORPORATION
 
  If the Recapitalization Merger Agreement is approved by the requisite vote
of the holders of shares of Company Common Stock at the Special Meeting,
promptly after the Recapitalization Effective Time, Alliance's Restated
Certificate of Incorporation, as amended, will be amended and restated so as
to read in its entirety in the form set forth as an exhibit to Amendment No. 1
to the Recapitalization Merger Agreement, which is included in Annex A and, as
so amended, until thereafter further amended as provided therein and under the
DGCL, will be the certificate of incorporation of Alliance following the
Recapitalization Effective Time. The Amended and Restated Certificate of
Incorporation will decrease the total number of shares of Alliance Common
Stock that Alliance is authorized to issue from 50,000,000 to 9,000,000 and
will decrease the total number of authorized shares of preferred stock that
Alliance is authorized to issue from 1,000,000 to 500,000. Of the 9,000,000
shares of common stock, 500,000 will be non-voting common stock (but will
otherwise be substantially identical to the voting common stock). The voting
common stock will be convertible into non-voting common stock at any time and
from time to time at the election of the holder thereof.
 
  Promptly after the Recapitalization Effective Time, the Company expects to
file a Certificate of Elimination with respect to the Company's Series C 5%
Cumulative Convertible Redeemable Preferred Stock, Series D 4% Cumulative
Redeemable Convertible Preferred Stock and Series E 4% Cumulative Redeemable
Convertible Preferred Stock.
 
  In addition, the Bylaws of Newco as in effect at the Recapitalization
Effective Time will be the Bylaws of Alliance following the Recapitalization
until thereafter changed or amended as provided therein or by applicable law.
 
PREFERRED STOCK
 
  Alliance is authorized by its Restated Certificate of Incorporation, as
amended, to issue an aggregate of 1,000,000 shares of preferred stock. The
Amended and Restated Certificate of Incorporation, to be adopted in connection
with the Recapitalization, authorizes the issuance of an aggregate of 500,000
shares of preferred stock.
 
                                      109
<PAGE>
 
SERIES F PREFERRED STOCK
 
  Alliance will issue 150,000 shares ($15.0 million stated amount) of Series F
Preferred Stock in connection with the Recapitalization. Holders of Series F
Preferred Stock are entitled to receive, when and as dividends on the Series F
Preferred Stock are declared by the Board of Directors out of funds legally
available therefor, cash dividends, at the rate per share of 13.5% per annum,
payable quarterly in arrears; provided, however, that the Company may, at its
option, pay such dividends in kind for the first five years from the issue
date. The Series F Preferred Stock has a liquidation preference of $100 per
share, is not convertible and carries no voting rights. The Series F Preferred
Stock is required to be redeemed for its liquidation preference plus accrued
but unpaid dividends 10 years from the issue date. The Series F Preferred
Stock is redeemable at the option of the Company at the following premiums,
expressed as a percentage of the accreted face value:

</TABLE>
 
The Series F Preferred Stock will rank senior to other capital stock of the
Company, including the shares of Alliance Common Stock to be retained by
stockholders in the Recapitalization. The Series F Preferred Stock will be
entitled, upon any liquidation or sale of the Company (including a sale of
assets, sale of stock, merger or otherwise), to a distribution of the
Company's assets prior to any payment to any other equity holders of the
Company. The purchasers of the Series F Preferred Stock in the
Recapitalization will be entitled to registration rights. Amendments to the
rights, preferences or privileges of the Series F Preferred Stock may be
effected only by obtaining the approval of the holders of two-thirds of the
outstanding Series F Preferred Stock.
 
                                 LEGAL MATTERS
 
  The validity of the shares of Alliance Common Stock being retained in the
Recapitalization is being passed upon for Alliance by Irell & Manella LLP, Los
Angeles, California.
 
  Irell & Manella LLP has delivered an opinion concerning certain Federal
Income tax consequences of the Recapitalization. See "THE RECAPITALIZATION--
Certain Tax Consequences of the Recapitalization."

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Alliance Imaging, Inc.
 
  We have audited the accompanying consolidated balance sheets of Alliance
Imaging, Inc. as of December 31, 1995 and 1996 and the related consolidated
statements of operations, cash flows and preferred stock, common stock,
additional paid-in capital and accumulated deficit for each of the three years
in the period ended December 31, 1996. These financial statements are the
responsibility of Alliance's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Alliance Imaging, Inc. at December 31, 1995 and 1996, and the consolidated
results of its operations and its cash flows for each of the three years in
the period ended December 31, 1996, in conformity with generally accepted
accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
       (INFORMATION AT SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1996 AND 1997 IS UNAUDITED)
 
 
1.  DESCRIPTION OF ALLIANCE AND BASIS OF FINANCIAL STATEMENT PRESENTATION
 
  DESCRIPTION OF ALLIANCE--Alliance Imaging, Inc. (Alliance) provides
outsourced radiology services and high technology diagnostic imaging systems
and related technical support services, as well as management and information
services, to hospitals and other healthcare providers. Diagnostic imaging
services are provided on both a mobile, shared-user basis as well as on a
full-time basis to single customers. Alliance operates entirely within the
United States and is one of the largest providers of magnetic resonance
imaging (MRI) and computed tomography (CT) services in the country. The
equipment used by Alliance is sophisticated and subject to accelerated
obsolescence in the event of significant technological change.
 
  BASIS OF FINANCIAL STATEMENT PRESENTATION--The accompanying consolidated
financial statements include the accounts of Alliance and its consolidated
subsidiaries. The accompanying unaudited consolidated financial statements
have been prepared by Alliance in accordance with generally accepted
accounting principles for interim financial information and with the
instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities
and Exchange Commission. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of Alliance, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation have been included. Operating results for the nine month period
ended September 30, 1997 are not necessarily indicative of the results that
may be expected for the year ending December 31, 1997.
 
  USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements
and accompanying notes. Actual results could differ from those estimates.
 
  DEBT RESTRUCTURING--Effective December 31, 1994, Alliance completed a
comprehensive debt restructuring with the holders of its senior notes and
senior subordinated debentures. The restructuring included a reduction in
interest rates, an exchange of a portion of the debentures for issuance of
redeemable preferred and common stock and the extension of the repayment terms
on all of the remaining debt. These transactions were accounted for as a
troubled debt restructuring. Supplemental loss per common share for the year
ended December 31, 1994, based on historical loss per share adjusted to give
effect to the issuance of common shares in exchange for debt in the debt
restructuring and a reduction of related interest expense assuming the
exchange had occurred on January 1, 1994, is ($1.77) based on 10,614,000
weighted average common shares outstanding.
 
  SPECIAL CHARGES--During the fourth quarter of 1994, Alliance recorded
special charges totaling $13,339,000 related to an equipment exchange
transaction, the impairment of certain equipment, debt restructuring and
employee severances. Alliance entered into an agreement with one of its major
equipment vendors to exchange several older MRI scanners for more
technologically advanced scanners which had been refurbished. The fair value
of the assets received, net of related debt incurred, was less than the net
book value of the assets exchanged, resulting in a non-cash pre-tax charge of
$2,156,000. Alliance also evaluated the carrying values of all of its
remaining older mid-field mobile MRI scanners. An impairment analysis of these
scanners resulted in an $8,670,000 non-cash pre-tax charge to reduce the net
book values to their estimated current market value. Alliance then identified
assets to be held for sale or other disposition and recorded a non-cash pre-
tax charge of $1,831,000 to write these assets down to their estimated net
realizable value on disposition. In addition, Alliance recorded pre-tax
special charges of $440,000 related to debt restructuring and $242,000 for
employee severances.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
       (INFORMATION AT SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1996 AND 1997 IS UNAUDITED)
 
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  CASH AND SHORT-TERM INVESTMENTS--Alliance considers short-term investments
with original maturities of three months or less to be cash equivalents.
 
  ACCOUNTS RECEIVABLE--Alliance provides shared and single-user diagnostic
imaging equipment and technical support services to the healthcare industry
and directly to patients on an outpatient basis. Substantially all of
Alliance's accounts receivable are due from hospitals, other healthcare
providers and health insurance providers located throughout the United States.
Services are generally provided pursuant to long-term contracts and directly
to patients, and generally collateral is not required. Receivables generally
are collected within industry norms for third-party payers. Credit losses are
provided for in the consolidated financial statements.
 
  EQUIPMENT--Equipment is stated at cost and is generally depreciated using
the straight-line method over an initial estimated life of three to eight
years to an estimated residual value, generally approximating between five and
20 percent of original cost. If Alliance continues to operate the equipment
beyond its initial estimated life, the residual value is then depreciated to a
nominal salvage value over three years.
 
  Routine maintenance and repairs are charged to expense as incurred. Major
repairs and purchased software and hardware upgrades, which extend the life or
add value to the equipment, are capitalized and depreciated over the remaining
useful life.
 
  With the exception of a small amount of office furniture and equipment,
substantially all of the property owned by Alliance relates to diagnostic
imaging equipment, tractors and trailers used in the business.
 
  GOODWILL--Alliance amortizes goodwill over a period of one to 25 years. For
acquired entities, the amortization period selected is primarily based upon
the estimated life of the customer contracts, including expected renewals, and
related other assets acquired, not to exceed 20 years. The Financial
Accounting Standards Board (FASB) issued Statement No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of", in March 1995. Statement 121 requires long-lived assets and certain
intangibles held and used by Alliance to be reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an
asset may not be recoverable. The recoverability test is to be performed at
the lowest level at which undiscounted net cash flows can be directly
attributable to long-lived assets. Alliance adopted Statement 121 in the first
quarter of 1996 with no material effect on Alliance's financial statements.
 
  REVENUE RECOGNITION--The majority of Alliance's revenues are derived
directly from healthcare providers. To a lesser extent, revenues are generated
from direct billings to patients or their medical payers which are recorded
net of contractual discounts and other arrangements for providing services at
less than established patient billing rates. Net revenues from direct patient
billing amounted to approximately 13%, 10% and 8% of revenues in the years
ended December 31, 1994, 1995 and 1996, respectively. No single customer
accounted for 3% or more of consolidated revenues in each of the three years
in the period ended December 31, 1996. All revenues are recognized at the time
the service is performed.
 
  INCOME TAXES--Alliance calculates deferred taxes and related income tax
expense using the liability method. This method determines deferred taxes by
applying the current tax rate to the cumulative temporary differences between
recorded carrying amounts and the corresponding tax basis of assets and
liabilities. A

valuation allowance is established for deferred tax assets unless their
realization is considered more likely than not. Alliance's provision for
income taxes is the sum of the change in the balance of deferred taxes between
the beginning and the end of the period plus income taxes currently payable.
 
  INVESTMENT TAX CREDITS--Alliance accounts for investment tax credits under
the flow through method.
 
  FAIR VALUES OF FINANCIAL INSTRUMENTS--FASB Statement No. 107, "Disclosures
about Fair Value of Financial Instruments," requires disclosure of fair value
information about financial instruments, whether or not recognized in the
balance sheet, for which it is practicable to estimate that value. In cases
where quoted market prices are not available, fair values are based on
estimates using present value or other valuation techniques. Those techniques
are significantly affected by the assumptions used, including the discount
rate and estimates of future cash flows. In that regard, the derived fair
value estimated cannot be substantiated by comparison to independent markets
and, in many cases, could not be realized in immediate settlement of the
instrument. Statement 107 excludes certain financial instruments and all
nonfinancial instruments from its disclosure requirements. Accordingly, the
aggregate fair value amounts presented do not represent the underlying value
of Alliance.
 
  The following methods and assumptions were used by Alliance in estimating
its fair value disclosures for financial instruments:
 
  Cash and short-term investments--The carrying amount reported in the balance
sheet for cash and cash equivalents approximates its fair value.
 
  Long-term debt--The fair values of Alliance's long-term debt are estimated
using discounted cash flow analyses, based on Alliance's current incremental
rates for similar types of borrowing arrangements.
 
    The carrying amounts and estimated fair values of Alliance's financial
                          instruments are as follows:

  As more fully discussed in Note 4, Alliance has repurchased all of its
redeemable preferred stock. Alliance paid approximately $2,788,000 to retire
the December 31, 1996 balance and consequently believes $2,788,000 reasonably
approximates the fair value of its redeemable preferred stock balance at
December 31, 1996. The original fair value of Alliance's redeemable preferred
stock of $15,500,000 was determined by independent valuation consultants as of
December 31, 1994. Although it was not practicable to reevaluate the estimated
fair value of the preferred stock as of December 31, 1995 because of the lack
of a quoted market price and the inability to estimate fair value without
incurring excessive costs, Alliance believes the $16,430,000 carrying amount
at December 31, 1995, which represents the original fair value of the
preferred stock increased for the 1995 cumulative dividend, reasonably
approximates its fair value at that date.

  EARNINGS PER COMMON SHARE--Earnings per common share have been computed
based on the weighted average number of shares outstanding during each period
plus the weighted average number of common equivalent shares outstanding that
are determined by the assumed exercise of dilutive stock options and warrants
less the number of treasury shares assumed to be purchased from the proceeds
using the average market price of Alliance's common stock. For the nine month
period ended September 30, 1997 common equivalent shares also include the
assumed conversion of the Series D convertible preferred stock into common
shares. Supplemental earnings per share for the nine months ended September
30, 1997 based on historical earnings per share adjusted assuming the
conversion of the senior bridge loan into Series D convertible preferred stock
had occurred on January 1, 1997 is $0.47 per share. This calculation ignores
amounts reported in the 1997 historical results as gain arising from the
repurchase of the senior subordinated debentures and as the earnings per share
benefit arising from the excess of carrying value of the preferred stock
repurchased over the consideration paid. Therefore, this supplemental earnings
per share calculation is the most comparable to the $0.48 per share "income
before items below" reported in Alliance's nine months ended September 30,
1997 historical results of operations. In February 1997, the FASB issued
Statement No. 128, "Earnings per Share", which is required to be adopted on
December 31, 1997. At that time, Alliance will be required to change the
method currently used to compute earnings per share and to restate all prior
periods. Under the new requirements for calculating basic earnings per share,
the dilutive effect of stock options, warrants and the Series D convertible
preferred stock will be excluded. The impact is expected to result in an
increase to basic earnings per share for the nine months ended September 30,
1996 and 1997 of $0.02 and $0.10 per share, respectively.

  The net change in Alliance's valuation allowance on deferred tax assets
during the year ended December 31, 1996 totaled $4,664,000 and $1,774,000 for
federal and state purposes, respectively.
 
  At December 31, 1996, for federal regular income tax purposes, Alliance had
approximately $26,400,000 of operating loss carryovers expiring through 2006.
Due to a change in ownership in November 1991, utilization of $19,700,000 of
these net operating losses is subject to an annual limitation of approximately
$2,200,000. Any unutilized annual limitation may be carried forward to future
years. The annual limitation may be increased if built-in gains which existed
on the date of the change in ownership are recognized by sale or other
disposal of equipment. As a result of these limitations, Alliance has
approximately $6,700,000 of operating loss carryovers available in 1997 for
federal regular income tax purposes. Future changes in the ownership of
Alliance could result in additional limitations on the utilization of its
operating loss carryovers.

  Installment obligations to lending institutions and the senior notes are
collateralized by equipment with a net book value of $77,339,000 at December
31, 1996.
 
  On December 31, 1996, Alliance entered into a Bridge Loan Agreement
(enabling Alliance to borrow up to $18,000,000) and borrowed $12,872,000 under
a senior bridge loan; an additional $5,128,000 was borrowed on January 2,
1997. The senior bridge loan is convertible into 18,000 shares of a new Series
D convertible preferred stock (see Note 5). On December 31, 1996, Alliance
used the proceeds of the senior bridge loan to repurchase $11,345,000 carrying
value of its senior subordinated debentures (debentures) and $11,071,000 of
its Series A redeemable preferred stock at a discount (plus related accrued
interest and dividends). As a result, in the fourth quarter of 1996, Alliance
recorded an extraordinary gain of $4,935,000, net of taxes of $560,000, from
this early extinguishment of debt. In addition, the excess of carrying amount
of preferred stock repurchased over consideration paid and other charges
amounted to $1,764,000, which has been recognized as an increase in additional
paid-in capital. In connection with this transaction, on January 2, 1997,
Alliance used the additional senior bridge loan proceeds to repurchase the
remaining balance of its debentures and Series A redeemable preferred stock at
a discount (plus related accrued interest and dividends). Accordingly, in
January 1997, Alliance

       (INFORMATION AT SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1996 AND 1997 IS UNAUDITED)
 
recorded an extraordinary gain of $1,332,000, net of taxes of $920,000, from
this early extinguishment of debt. The excess of carrying amount of preferred
stock repurchased over consideration paid in January 1997 amounted to
$1,906,000.
 
  On March 26, 1997, the holder of the senior bridge loan exercised its option
to convert the senior bridge loan into 18,000 shares of Series D convertible
preferred stock. At that time, senior notes not to exceed $9,000,000 held by
the same lender become convertible into a new Series E preferred stock on or
after January 1, 1998 (see Note 5). Supplemental earnings per share for the
year ended December 31, 1996, based on historical earnings per share adjusted
to give effect to (1) the issuance of the Series D preferred stock, and (2)
the use of the $18 million proceeds therefrom on a pro rata basis to
repurchase the debentures and Series A redeemable preferred stock repurchased
in December 1996 and January 1997, and assuming the transactions had occurred
on January 1, 1996, is $0.45 per share. This calculation ignores amounts
reported in the historical results for 1996 as gains arising from the
repurchase of the senior notes and debentures and as the earnings per share
benefit arising from the excess of the carrying value of the preferred stock
repurchased over the consideration paid. Therefore, this supplemental earnings
per share calculation is most comparable to the $0.48 per share "income before
items below" reported in Alliance's 1996 historical results of operations.
 
  In November 1996, Alliance arranged for the sale of all of its senior notes
by the original holders to new owners. In connection with the sale, Alliance
prepaid $5,300,000 of the senior notes at a discount and recorded an
extraordinary gain of $1,365,000, net of taxes of $155,000, from this early
extinguishment of debt. In addition, the new holders and Alliance agreed to
remove or modify various restrictive covenants contained in the note purchase
agreement governing the senior notes. The amended senior notes bear interest
at a stated annual rate of 7.5%, with interest payable monthly, and require
minimum mandatory quarterly principal payments of $150,000 in 1997 increasing
to $1,800,000 in 2003. Alternatively, Alliance may make voluntary monthly
principal and interest payments of $335,000 through October 2002 to fully
retire the notes. Alliance may also prepay the notes at any month end at
specified discounts from their face amount. The senior notes agreement
contains limitations on equipment additions, incurrence of debt and other
similar items.
 
  The carrying amount of long-term debt as of December 31, 1996 is due as
follows (assuming voluntary prepayments of Alliance's senior notes, and
excluding the senior bridge loan, which was converted to preferred stock in
March 1997, and the debentures refinanced thereby):

  Alliance has a $3 million revolving line of credit with a bank. The line
bears interest at the bank's prime rate (8.5% at December 31, 1995 and 8.25%
at December 31, 1996) plus two percent, with a commitment fee of 0.375% per
year on the unused balance, and is secured by substantially all of Alliance's
accounts receivable. The line of credit had not been utilized through December
31, 1996.
 
5. PREFERRED AND COMMON STOCK
 
  PREFERRED STOCK--Alliance is authorized to issue 1,000,000 shares of
preferred stock, undesignated as to series. The Board of Directors has the
authority to establish the voting powers, designations, preferences and other
special rights for each series of preferred stock issued.
 
  In connection with Alliance's debt refinancing effective December 31, 1996
(see Note 4), Alliance authorized 18,000 shares of a new Series D convertible
preferred stock and 9,000 shares of a new Series E convertible preferred
stock. The holders of the Series D and E convertible preferred stock, when
issued, are entitled to receive cumulative dividends at the rate of 4% per
annum of the stated liquidation value (subject to increase, to a maximum of
8%, under certain circumstances). Unpaid dividends accumulate and are payable
quarterly by Alliance in cash. Shares of Series D convertible preferred stock
are convertible at the option of the holder at any time on or before December
31, 2006 into shares of common stock at a conversion price of $6.00 per common
share, subject to adjustment. Shares of Series E convertible preferred stock
are convertible at the option of the holder at any time on or before December
31, 2006 into shares of common stock at a conversion price of the greater of
$6.00 per share of common stock or the market price (as defined) per common
share at date of issuance of the Series E convertible preferred stock. Shares
of Series D and E convertible preferred stock are subject to redemption at the
option of Alliance after December 31, 2006.
 
  In connection with the Royal acquisition (Note 8), Alliance issued 3,876
shares of a new Series C convertible preferred stock. The Series C convertible
preferred stock bears a dividend of 5% of its original liquidation value
($388,000) payable annually in cash and is redeemable at Alliance's option.
Holders of Series C convertible preferred stock may convert their stock into
common stock at a price of $5.00 per common share.
 
  In the event of liquidation, dissolution or winding up of Alliance, the
holders of Series C, D and E convertible preferred stock shall be entitled to
receive an amount equal to the stated liquidation value per share (plus
accumulated but unpaid dividends) prior to any distributions to common
stockholders. No sinking fund has been or will be established for the
retirement or redemption of shares of Series C, D or E convertible preferred
stock.
 
  The holders of shares of preferred stock are not entitled to any voting
rights with respect to any matters voted upon by the common stockholders.
However, a majority of preferred stockholders (with each series voting as a
single class) must approve certain corporate transactions including the
authorization of additional classes or series of stock ranking prior to their
stock, any increase in the number of authorized shares of their preferred
stock series, any amendment to the terms of such preferred stock series and
similar actions.
 
  STOCK OPTIONS AND AWARDS--Alliance has elected to follow Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees"
(APB 25) and related Interpretations in accounting for its employee stock
options because, as discussed below, the alternative fair value accounting
provided for under FASB Statement No. 123, "Accounting for Stock-Based
Compensation," requires use of option valuation models that were not developed
for use in valuing employee stock options. Under APB 25, because the exercise
price of Alliance's employee stock options equals the market price of the
underlying stock on the date of grant, no compensation expense is recognized.

  Alliance's 1991 Stock Option Plan provides that up to 2,000,000 shares may
be granted to management and key employees. Options are granted at their fair
market value at the date of grant. All options granted have 10 year terms and
vest and become fully exercisable at the end of three to four years of
continued employment. The weighted-average remaining contractual life of
options outstanding as of December 31, 1996 is 9.6 years. The following table
summarizes the activity under this plan.

  At December 31, 1996, 430,700 of these options were exercisable at $0.4375,
121,050 were exercisable at $3.5625, and 12,667 were exercisable at prices
between $1.6875 and $2.375.
 
  In 1991, options for 30,000 shares not covered by the 1991 Stock Option Plan
were granted to three non-employee directors at an exercise price of $8.25 per
share. In 1993, options for 40,000 shares were granted at exercise prices
ranging from $1.125 to $2.50 per share. In 1995, options for an additional
10,000 shares were granted at an exercise price of $1.6875 per share. These
options vest over a four year period. At December 31, 1996, options for 40,000
shares had been canceled and options for 30,000 shares were exercisable.
 
  Pro forma information regarding net income and earnings per share is
required by Statement 123, which also requires that the information be
determined as if Alliance has accounted for its employee stock options granted
subsequent to December 31, 1994 under the fair value method of that Statement.
The fair value for these options was estimated as of the date of grant using a
Black-Scholes option pricing model with the following weighted-average
assumptions for 1996: risk-free interest rate of 5.72%; no dividend yield;
volatility factor of the expected market price of Alliance's common stock of
 .43; and a weighted-average expected life of the option of seven years. The
weighted-average fair value of options granted during 1996 is $1.93.
 
  The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because Alliance's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a
reliable single measure of the fair value of its employee stock options.

terms of three to ten years. The weighted-average grant-date fair value of the
warrants was $2.13.
 
6. COMMITMENTS
 
  Alliance has contracts with its equipment vendors for comprehensive
maintenance and cryogen coverage for its MRI and CT systems. The contracts are
between one and five years and extend through December 2001, but may be
canceled by Alliance under certain circumstances. Contract payments are
approximately $9,200,000 per year. At December 31, 1996, Alliance had binding
equipment purchase commitments totaling approximately $29,200,000.
 
  Alliance leases office and warehouse space and certain equipment under non-
cancelable operating leases. The office and warehouse leases generally call
for minimum monthly payments plus maintenance and inflationary increases. The
future minimum payments under such leases are as follows:

</TABLE>
 
  Alliance's total rental expense, which includes short-term equipment
rentals, for the years ended December 31, 1994, 1995 and 1996 was $2,781,000,
$1,923,000 and $3,380,000, respectively.
 
7. 401(K) SAVINGS PLAN
 
  Alliance established a 401(k) Savings Plan in January 1990. All employees of
Alliance are eligible to participate after a six month waiting period.
Employees may contribute between 1% and 15% of their annual compensation.
Alliance matches 33.3 cents for every dollar of employee contributions up to
7% of their compensation, subject to the limitations imposed by the Internal
Revenue Code. Alliance may also make discretionary contributions depending on
profitability. Alliance incurred and charged to expense $119,000, $140,000 and
$157,000 during 1994, 1995 and 1996, respectively, related to the plan.
 
8. ACQUISITION
 
  On April 26, 1996, Alliance acquired all of the outstanding shares of Royal
Medical Health Services, Inc. (Royal) of Pittsburgh, Pennsylvania. Like
Alliance, Royal is a provider of comprehensive MRI services. Alliance issued
3,876 shares of Series C convertible preferred stock valued at $388,000,
common stock warrants valued at $212,000, and paid $1,914,000 in cash as
consideration for the acquisition of Royal and certain related assets. The
acquisition has been accounted for as a purchase and, accordingly, the results
of operations of Royal have been included in Alliance's consolidated financial
statements from the date of acquisition.

9. SUBSEQUENT EVENTS     
 
  On July 23, 1997, Alliance entered into an Agreement and Plan of Merger as
amended, (the "Recapitalization Merger Agreement"). Under the terms of the
Recapitalization Merger Agreement, an entity formed by affiliates of Apollo
Management, L.P. (collectively, "Apollo") will merge with and into Alliance
(the "Recapitalization"). Each share of Alliance common stock, par value $.01
per share, issued and outstanding immediately prior to the effective time of
the Recapitalization, other than dissenting shares, either (1) will be
converted into the right to receive $11.00 in cash or (2) will be retained by
such stockholder. The Recapitalization Merger Agreement requires that 411,358
shares in the aggregate of common stock be retained by Alliance's existing
shareholders; therefore, the right to receive either $11.00 in cash for each
share or to retain that share of Alliance common stock is subject to
proration.
 
  The proposed Recapitalization is subject to stockholder approval. However,
pursuant to a Stockholder Agreement, stockholders representing beneficial
ownership of not less than 54.4% of Alliance common stock (the "Stockholders")
have agreed to vote all shares beneficially owned by them in favor of the
approval of the Recapitalization Merger Agreement and the Recapitalization and
to convert or exercise all securities they hold that are convertible into or
exercisable for shares of Alliance common stock prior to the time of the
special meeting of shareholders called in connection with the
Recapitalization. In addition, each Stockholder has granted to Apollo an
option to acquire their shares of common stock, and a proxy to vote such
shares in favor of the Recapitalization. At the closing of the
Recapitalization, significant new sources of financing will be provided to
Alliance for the purchase of shares of common stock in the Recapitalization,
repayment of indebtedness, and for working capital purposes, among other uses.
 
  The Recapitalization Merger Agreement originally contemplated that, in
connection with the closing of the Recapitalization, Alliance would also
acquire all of the capital stock of the parent corporation of SMT Health
Services, Inc. ("SMT") from Apollo, in exchange for additional shares of
Alliance common stock. The Recapitalization Merger Agreement has been amended
to eliminate that transaction; as a result, SMT will not be acquired by
Alliance in connection with the Recapitalization, and instead will remain an
independent company owned by Apollo.
 
  After the consummation of the Recapitalization, the Company will adopt a new
employee stock option plan pursuant to which options (the "New Options") with
respect to a total of 454,545 shares of Alliance common

stock (the "New Option Shares") will be available for grant. The New Option
Shares will be allocated in amounts agreed upon between Apollo and the
Company. Of the New Option Shares, 50% will vest in equal increments over four
years ending on the fourth anniversary of the last day of the consummation of
the Recapitalization. The remaining 50% will vest seven and one-half years
after the date of grant, subject to acceleration if certain per-share equity
targets are achieved. Vesting of New Options occurs only during an employee's
term of employment. The exercise price for the New Options is expected to be
at the fair market value at a grant date (i.e., $11.00 per share at the
consummation of the Recapitalization)."
   
  As a part of the new financing to be provided, Alliance plans to sell $165
million of Senior Subordinated Notes (the "Notes") in an underwritten public
offering. The Notes are to be unconditionally guaranteed, on a senior
subordinated basis, jointly and severally, by all significant direct and
indirect consolidated subsidiaries of Alliance, which consist of Royal Medical
Health Services, Inc., Alliance Imaging of Central Georgia, Inc., Alliance
Imaging of Ohio, Inc. and Alliance Imaging of Michigan, Inc. (collectively,
the "Subsidiary Guarantors"). Separate financial statements of the Subsidiary
Guarantors are not included herein because such guarantors are jointly and
severally liable with respect to Alliance's obligations pursuant to the Notes,
and the aggregate net assets, earnings and equity of the Subsidiary Guarantors
and Alliance are substantially equivalent to the net assets, earnings and
equity of Alliance on a consolidated basis. Accordingly, management has
determined that separate financial statements and other disclosures concerning
the Subsidiary Guarantors would not provide material information to
prospective purchasers of the Notes. Combined summarized financial information
for the Subsidiary Guarantors is set forth below (in thousands):

  AGREEMENT AND PLAN OF MERGER (this "Agreement") dated as of July 23, 1997,
between NEWPORT INVESTMENT LLC, a Delaware limited liability company
("Investor"), and ALLIANCE IMAGING, INC., a Delaware corporation (the
"Company").
 
  WHEREAS, the Board of Directors of the Company has determined that it is
fair and in the best interests of its stockholders for a corporation to be
formed, and wholly-owned, by Investor, to merge with and into the Company (the
"Merger") pursuant to Section 251 of the Delaware General Corporation Law
("DGCL") upon the terms and subject to the conditions set forth herein;
 
  WHEREAS, the Board of Directors of the Company has adopted resolutions
approving the Merger, this Agreement and the transactions to which the Company

approve the Merger and this Agreement;
 
  WHEREAS, the parties have agreed (subject to the terms and conditions of
this Agreement), as soon as practicable following the approval by the
stockholders of the Company, to effect the Merger, as more fully described
herein;
 
  WHEREAS, it is intended that the Merger be treated as a recapitalization of
the Company for financial reporting purposes;
 
  WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Investor to enter into this Agreement, Investor and certain
stockholders of the Company are entering into a Stockholder Agreement (the
"Stockholder Agreement") pursuant to which such stockholders have, among other
things, granted to Investor an irrevocable proxy to vote their Shares (as
hereinafter defined) in favor of the Merger and all other actions necessary to
consummate the Merger, upon the terms and subject to the conditions set forth
in the Stockholder Agreement;
 
  WHEREAS, concurrently with the execution of this Agreement and as an
inducement to Investor to enter into this Agreement, the Company and certain
members of the Company's senior management are executing and delivering the
Employment Agreements, in substantially the form attached hereto as EXHIBIT A
(the "Employment Agreements") pursuant to which such persons have, among other
things, agreed to certain confidentiality and non-solicitation covenants; and
 
  WHEREAS Investor and the Company desire to make certain representations,
warranties, covenants and agreements in connection with the Merger and also to
prescribe various conditions to the Merger.
 
  NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements herein contained, and intending to be legally bound hereby,

                                  THE MERGER
 
1.1 THE MERGER.
 
  Prior to the Effective Time (as defined below), Investor shall form a new

Newco shall be merged with and into the Company as soon as practicable
following the satisfaction or waiver, if permissible, of the conditions set
forth in Article VII hereof. The Company shall be the surviving corporation in
the Merger (the "Surviving Corporation") and shall continue its existence
under the laws of Delaware. The separate corporate existence of Newco shall
cease.
 
1.2 CONSUMMATION OF THE MERGER.
 
  Subject to the provisions of this Agreement, the parties hereto shall cause
the Merger to be consummated by filing with the Secretary of State of the
State of Delaware a duly executed and verified certificate of merger, as
required by the DGCL, and shall take all such other and further actions as may
be required by law to make the Merger effective as promptly as practicable.
Prior to the filing referred to in this Section, a closing (the "Closing")
will be held at the offices of O'Sullivan Graev & Karabell, LLP, 30
Rockefeller Plaza, 41st Floor, New York, New York (or such other place as the
parties may agree) for the purpose of confirming all the foregoing. The time
the Merger becomes effective in accordance with applicable law is referred to
as the "Effective Time."
 
1.3 EFFECTS OF THE MERGER.
 
  The Merger shall have the effects set forth in the applicable provisions of
the DGCL and set forth herein.
 
1.4 CERTIFICATE OF INCORPORATION AND BYLAWS.
 
  (a) The Restated Certificate of Incorporation of the Company (the
"Certificate of Incorporation"), as in effect immediately prior to the
Effective Time, shall be the certificate of incorporation of the Surviving
Corporation until thereafter changed or amended as provided therein or by
applicable law.
 
  (b) The by-laws of Newco (the "By-laws") as in effect immediately prior to
the Effective Time shall be the by-laws of the Surviving Corporation, until
thereafter changed or amended as provided therein or by applicable law.
 
1.5 DIRECTORS AND OFFICERS.
 
  The directors of Newco immediately prior to the Effective Time and the
officers of the Company immediately prior to the Effective Time shall be the
directors and officers, respectively, of the Surviving Corporation until their
respective successors are duly elected and qualified.
 
1.6 COMPANY ACTIONS.
 
  The Company hereby represents and warrants that (a) its Board of Directors
(at a meeting duly called and held), has (i) determined that the Merger (upon
the terms and subject to the conditions of this Agreement) is fair to and in
the best interests of the stockholders of the Company, (ii) resolved to
approve this Agreement, the Merger, the issuance of shares of common stock of
the Company, par value $0.01 per share (the "Shares") to the Investor as sole
shareholder of Newco in connection with the Merger, and to recommend (subject
to Section 5.2 of this Agreement) approval of the Merger and this Agreement by
the stockholders of the Company, (iii) taken all necessary steps to render
Section 203 of the DGCL inapplicable to the Merger and the transactions
 
                                     A-I-5
<PAGE>
 
contemplated by this Agreement, and (iv) resolved to elect not to be subject,
to the extent permitted by law, to any state takeover law other than Section
203 of the DGCL that may purport to be applicable to the Merger, or the
transactions contemplated by this Agreement, and (b) Salomon Brothers Inc (the
"Financial Advisor") has advised the Company's Board of Directors that, in its
opinion, the consideration to be received and retained by the Company's
stockholders in the Merger is fair, from a financial point of view, to such
stockholders.
 
                                  ARTICLE II
 
                             EFFECTS OF THE MERGER
 
2.1 STOCKHOLDERS' MEETING.
 
  (a) Subject to Section 5.2 of this Agreement, the Company, acting through
its Board of Directors, shall, in accordance with applicable law, duly call,
give notice of, convene and hold a special meeting (the "Special Meeting") of
its stockholders as soon as practicable for the purpose of obtaining the
approval of this Agreement, include in the registration statement on Form S-4
that includes a proxy statement relating to any required approval by or
meeting of the Company's stockholders with respect to this Agreement and the
Merger (the "Proxy Statement/Prospectus") for use in connection with the
Special Meeting, the recommendation of the Company's Board of Directors that
stockholders of the Company vote in favor of the Merger and approve this
Agreement. The Investor and, subject to Section 5.2 of this Agreement, the
Company agree to use commercially reasonable efforts to cause the Special
Meeting to occur as soon as possible under applicable law and the Company's
Bylaws after the Company has responded to all SEC comments with respect to the
preliminary Proxy Statement/Prospectus as provided in Section 6.1.
 
  (b) Prior to the mailing of the Proxy Statement/Prospectus, Newco shall
appoint an independent bank or trust company to act as paying agent (the
"Paying Agent"), which Paying Agent shall be reasonably satisfactory to the
Company, for the payment of the cash portion of the Merger Consideration.
 
2.2 RETAINED SHARE ELECTIONS.
 
  (a) Each person who is a record holder of Shares on or prior to 5:00 p.m.,
New York City time, on the date of the Special Meeting or the date of any
meeting of stockholders held pursuant to any adjournment of the Special
Meeting (the "Election Date") will be entitled, with respect to all or any
portion of his or its Shares, to make an election to retain Shares as set
forth in, and subject to the provisions of this Section 2.2.
 
  (b) The Company shall prepare and mail a form of election, which form shall
be subject to the approval of Investor (the "Election Form"), with the Proxy
Statement/Prospectus to the record holders of Shares as of the record date for
the Special Meeting, which Election Form shall be used by each record holder
of Shares who wishes to elect to retain Shares in lieu of such Shares being
converted into the right to receive the Cash Merger Price (as defined below)
for each such Share. Notwithstanding anything to the contrary contained in
this Agreement, any such election shall be subject to proration as set forth
below. The Company will use commercially reasonable efforts to make the
Election Form and the Proxy Statement/Prospectus available to all persons who
become holders of Shares during the period between such record date and the
Election Date. Any such holder's election to retain Shares shall have been
validly made only if the Paying Agent shall have received at its designated
office, on or prior to the Election Date, an Election Form properly completed
and signed in accordance with such rules as the Paying Agent may establish
pursuant to Section 2.2(e), and accompanied by either (i) certificates for the
Shares to which such Election Form relates, duly endorsed in blank or
otherwise in form acceptable for transfer on the books of the Company or (ii)
an appropriate guarantee of delivery of such certificates as set forth in such
Election Form from a firm which is a member of a registered national
securities exchange or of the National Association of Securities Dealers,
Inc., or a commercial bank or trust company having an office or correspondent
in the United States (a "Notice of Guaranteed Delivery"). Notwithstanding
anything to the contrary contained herein, any Election Form accompanied by a
Notice of Guaranteed Delivery shall be deemed not validly made if the
certificate or certificates are in fact delivered to the Paying Agent after
three (3) Nasdaq Stock Market trading days after the date of execution of such
guarantee of delivery.
 
                                     A-I-6
<PAGE>
 
  (c) Any Election Form may be revoked by the stockholder submitting such
Election Form if a written notice of revocation is received by the Paying
Agent prior to 5:00 p.m., New York City time, on the Election Date. In
addition, all Election Forms shall be revoked automatically if this Agreement
is terminated pursuant to Section 8.1. If an Election Form is revoked, the
certificate or certificates (or guarantees of delivery, as appropriate) for
the Shares to which such Election Form relates shall be returned by the Paying
Agent to the stockholder submitting the same to the Paying Agent.
 
  (d) For purposes of this Agreement, (i) "Elected Retained Share" shall mean
a Share in respect of which an election to retain such Share is validly made
and not validly revoked prior to the Election Date and (ii) "Elected Cash
Share" shall mean a Share in respect of which either an election to retain
such Share is not validly made prior to the Election Date or an election to
retain such Share is validly revoked prior to the Election Date.
 
  (e) The Paying Agent may, with the mutual agreement of the Investor and the
Company, make such rules as are consistent with this Section 2.2 for the
implementation of the elections provided for herein as shall be necessary or
desirable fully to effect such elections.
 
  (f) The Paying Agent shall determine (i) whether or not elections to retain
Shares have been validly made or validly revoked pursuant to this Section 2.2
and (ii) when elections and revocations have been received by it. If the
Paying Agent determines that any election to retain Shares was not validly
made, such Shares shall be converted in the Merger into the right to receive
the Cash Merger Price (as defined below). The Paying Agent shall also make all
computations as to the allocation and the proration contemplated by Section
2.4. All determinations and calculations by the Paying Agent shall be
conclusive and binding on the holders of Shares.
 
2.3 CONVERSION OF SHARES.
 
  (a) All Shares held in the treasury of the Company (the "Excluded Shares")
shall be canceled and shall cease to exist as of the Effective Time, without
any consideration being payable therefore.
 
  (b) Notwithstanding anything in this Agreement to the contrary, Shares which
would otherwise constitute Elected Cash Shares or Non-Elected Cash Shares
hereunder, which are issued and outstanding immediately prior to the Effective
Time and which are held by stockholders who did not vote in favor of the
Merger and who comply with all of the relevant provisions of Section 262 of
the DGCL (the "Dissenting Shares") shall not be converted into or be
exchangeable for the right to receive the Cash Merger Price (as defined
below), but instead shall be converted into the right to receive payment from
the Surviving Corporation with respect to such Dissenting Shares in accordance
with the DGCL, unless and until such holders shall have effectively withdrawn
or lost their rights to appraisal under the DGCL. If any such holder shall
have effectively withdrawn or lost such right, such holder's Shares shall be
converted into the right to receive the Cash Merger Price (as defined below).
The Company shall give prompt notice to the Investor of any demands received
by the Company for appraisal of Shares, and the Investor shall have the right
to participate in and direct all negotiations and proceedings with respect to
such demands. The Company shall not, except with the prior written consent of
the Investor, make any payment with respect to, or settle or offer to settle,
any such demands.
 
  (c) By virtue of the Merger, each Share issued and outstanding immediately
prior to the Effective Time, other than Excluded Shares and Dissenting Shares,
shall be retained or converted into the right to receive cash as follows:
 
    (i) Each Share that is an Elected Retained Share and each Share that is a
  Non-Elected Retained Share (as defined in Section 2.4(c)) (in either case,
  a "Retained Share") shall be retained by the holder thereof following the
  Effective Time, shall remain outstanding and shall represent one share of
  Common Stock, par value $.01 per share, of the Surviving Corporation; and
 
    (ii) Each Share that is an Elected Cash Share and each Share that is a
  Non-Elected Cash Share (as defined in Section 2.4(b)) shall be converted
  into the right to receive from the Surviving Corporation $11.00 in cash
  (the "Cash Merger Price").
 
                                     A-I-7
<PAGE>
 
2.4 PRORATION.
 
  (a) Notwithstanding anything in this Agreement to the contrary, the
aggregate number of Retained Shares (the "Actual Retained Share Number") shall
be equal to 727,273 Shares.
 
  (b) If the aggregate number of Shares constituting Elected Retained Shares
(the "Elected Retained Share Number") exceeds the Actual Retained Share
Number, then the number of Shares which shall be Retained Shares pursuant to
Section 2.3(c)(i) shall be reduced by such excess number of Shares (each such
Share included among such excess, a "Non-Elected Cash Share"). In such event,
each holder of Elected Retained Shares shall be allocated Non-Elected Cash
Shares in lieu of Retained Shares such that (after giving effect to Section
2.6(e)) each such holder shall be deemed to hold Non-Elected Cash Shares in an
amount equal to (x) the total number of Elected Retained Shares held by such
holder less (y) the product of (A) a fraction, the numerator of which is the
Actual Retained Share Number, and the denominator of which is the Elected
Retained Share Number, multiplied by (B) the total number of Elected Retained
Shares held by such holder.
 
  (c) If the Actual Retained Share Number is greater than the Elected Retained
Share Number, then the aggregate number of Shares which shall be converted
into the right to receive cash pursuant to Section 2.3(c)(ii) shall be
decreased by a number of Shares equal to the excess of the Actual Retained
Share Number over the Elected Retained Share Number (each Share included among
such excess, a "Non-Elected Retained Share"). In such event, each holder of
Elected Cash Shares (other than the Investor) shall be allocated a portion of
the Non-Elected Retained Shares in lieu of Elected Cash Shares (after giving
effect to Section 2.6(e)) equal to (i) the number of Elected Cash Shares held
by such holder, multiplied by (ii) a fraction, the numerator of which is the
number of Non-Elected Retained Shares and the denominator of which is the
aggregate number of Elected Cash Shares held by all holders (other than the
Investor).
 
2.5 CONVERSION OF COMMON STOCK OF NEWCO.
 
  (a) The shares of common stock, par value $.01 per share ("Newco Share"), of
Newco, issued and outstanding immediately prior to the Effective Time shall,
by virtue of the Merger and without any action on the part of the holder
thereof, be converted into and become at the Effective Time 3,363,636 shares
of Common Stock of the Surviving Corporation.
 
  (b) If the Investor shall purchase Shares prior to the Effective Time
pursuant to the Stockholder Agreement, a number of such Shares, to be
determined in Investor's discretion, may be contributed by the Investor to
Newco immediately prior to the Effective Time and shall be cancelled and shall
cease to exist as of the Effective Time without any consideration being
payable therefor. Any other Shares purchased by the Investor shall be retained
by the Investor and shall be entitled to receive the Cash Merger Price (but
shall not be treated as Retained Shares).
 
2.6 EXCHANGE OF CERTIFICATES.
 
  (a) As soon as reasonably practicable as of or after the Effective Time of
the Merger, Newco shall deposit with the Paying Agent, for the benefit of the
holders of Shares, for payment in accordance with this Article II, the funds
necessary to pay the Cash Merger Price for each Share.
 
  (b) As soon as practicable after the Effective Time of the Merger, each
holder of an outstanding certificate or certificates which prior thereto
represented Shares, upon surrender to the Paying Agent of such certificate or
certificates and acceptance thereof by the Paying Agent, shall be entitled to
a certificate or certificates representing the number of full Retained Shares
of the Surviving Corporation, if any, to be retained by the holder thereof as
Retained Shares pursuant to this Agreement and the amount of cash, if any,
into which the number of Shares previously represented by such certificate or
certificates surrendered shall have been converted pursuant to this Agreement.
The Paying Agent shall accept such certificates upon compliance with such
reasonable terms and conditions as the Paying Agent may impose to effect an
orderly exchange thereof in accordance with normal
 
                                     A-I-8
<PAGE>
 
exchange practices. After the Effective Time of the Merger, there shall be no
further transfer on the records of the Company or its transfer agent of
certificates representing Shares which have been converted, in whole or in
part, pursuant to this Agreement, into the right to receive cash, and if such
certificates are presented to the Company for transfer, they shall be canceled
against delivery of such cash. If any certificate for Retained Shares is to be
issued in, or if cash is to be remitted to, a name other than that in which
the certificate for Shares surrendered for exchange is registered, it shall be
a condition of such exchange that the certificate so surrendered shall be
properly endorsed, with signature guaranteed or otherwise in proper form for
transfer and that the person requesting such exchange shall pay to the Company
or its transfer agent any transfer or other taxes required by reason of the
issuance of certificates for such Retained Shares in a name other than that of
the registered holder of the certificate surrendered, or establish to the
satisfaction of the Company or its transfer agent that such tax has been paid
or is not applicable. Until surrendered as contemplated by this Section
2.6(b), each certificate for Shares shall be deemed at any time after the
Effective Time of the Merger to represent only the right to receive upon such
surrender the Cash Merger Price for each Share (other than any Retained Share)
and a new certificate for each Retained Share, as contemplated by Section 2.1.
 
  (c) No dividends or other distributions with respect to Retained Shares with
a record date after the Effective Time of the Merger shall be paid to the
holder of any certificate for Shares not surrendered with respect to the
Retained Shares represented thereby and no cash payment in lieu of fractional
Shares shall be paid to any such holder pursuant to Section 2.6(e) until the
surrender of such certificate in accordance with this Article II. Subject to
applicable law, following surrender of any such certificate, there shall be
paid to the holder of the certificate representing whole Retained Shares
issued in connection therewith, without interest (i) at the time of such
surrender, the amount of any cash payable in lieu of a fractional retained
share to which such holder is entitled pursuant to Section 2.6(e) and the
proportionate amount of dividends or other distributions with a record date
after the Effective Time of the Merger therefor paid with respect to such
Retained Shares, and (ii) at the appropriate payment date, the proportionate
amount of dividends or other distributions with a record date after the
Effective Time of the Merger but prior to such surrender and a payment date
subsequent to such surrender payable with respect to such whole Retained
Shares.
 
  (d) All cash paid upon the surrender for exchange of certificates
representing Shares in accordance with the terms of this Article II (including
any cash paid pursuant to Section 2.6(e)) shall be deemed to have been paid in
full satisfaction of all rights pertaining to the Shares exchanged for cash
theretofore represented by such certificates.
 
  (e) Notwithstanding any other provision of this Agreement, each holder of
Shares retained pursuant to the Merger who would otherwise have been entitled
to retain a fraction of a Retained Share (after taking into account all Shares
delivered by such holder) shall receive, in lieu thereof, a cash payment
(without interest) equal to such fraction multiplied by the Cash Merger Price.
 
  (f) Any cash deposited with the Paying Agent pursuant to this Section 2.6
(the "Exchange Fund") which remains undistributed to the holders of the
certificates representing Shares 180 days after the Effective Time of the
Merger shall be delivered to the Surviving Corporation at such time and any
holders of Shares prior to the Merger who have not theretofore complied with
this Article II shall thereafter look only to the Surviving Corporation and
only as general unsecured creditors thereof for payment of their claim for
cash, if any.
 
  (g) None of Newco or the Company or the Paying Agent shall be liable to any
person in respect of any cash from the Exchange Fund delivered to a public
office pursuant to any applicable abandoned property, escheat or similar law.
If any certificates representing Shares shall not have been surrendered prior
to one year after the Effective Time of the Merger (or immediately prior to
such earlier date on which any cash in respect of such certificate would
otherwise escheat to or become the property of any Governmental Entity (as
defined below)), any such cash in respect of such certificate shall, to the
extent permitted by applicable law, become the property of the Surviving
Corporation, free and clear of all claims or interest of any person previously
entitled thereto.
 
                                     A-I-9
<PAGE>

  (a) The Company has filed with the SEC all reports, forms, schedules and

complied in all material respects with the requirements of the Securities Act,
or the Exchange Act, as the case may be, and the rules and regulations of the
SEC promulgated thereunder applicable to such SEC Documents, and (ii) none of
the SEC Documents contained any untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary in order

Management of the Company has no reason to believe that with respect to its
and its Subsidiaries' long-lived assets and intangible assets which are

undiscounted future cash flows related to such assets did not exceed the

indebtedness has an existing right, contingent or otherwise, to be secured)
any Lien on property or assets of the Company or any Subsidiary, capital lease
obligations, and obligations in respect of guarantees of any of the foregoing
or any "keep well" or other agreement to maintain any financial statement
condition of another person, in each case, whether or not matured, liquidated,
fixed, contingent, or disputed.

schedule that includes a general description of each MRI Unit and CT unit
(including upgrades thereto) owned or subject to capital lease obligations by
the Company or any Subsidiary as of that date, and (ii) as of the date of this
Agreement, a list (the "Commitments List") of all outstanding commitments by

of accounting other than GAAP), and fairly present, in all material respects,
the financial position of GMIC as of the dates thereof and the results of its
operations and cash flows (except the June 30, 1997 financial statements,
which do not contain a statement of cash flows) for the periods then ended
(subject, in the case of unaudited statements, to normal year end
adjustments).

  (c) Schedule 3.14(c) or the Recent SEC Documents sets forth a description of
all transactions between the Company or its Subsidiaries, on the one hand, and
any of their respective Affiliates, directors, officers, employees, or
consultants, on the other hand, in each case consummated at any time since
January 1, 1996 (except for ordinary course commercial transactions involving
MRI Units, CT Units and related equipment, and the maintenance thereof, with
General Electric Company and its Affiliates (a "GE Transaction")). Except as
set forth on Schedule 3.14(c) or reflected in the Recent SEC Documents, or
pursuant to a GE Transaction, there are no agreements or arrangements between
the Company or its Subsidiaries, on the one hand, and any of their respective
Affiliates, directors, officers, employees or consultants, on the other hand,
with respect to any such transactions. No Affiliate, director, officer,
employee or consultant of the Company owns any interest in any asset or
property (real or personal, tangible or intangible), business or contract used
or intended for use or otherwise relating to the business currently conducted
or proposed to be conducted by the Company or any Subsidiary, other than
pursuant to a GE Transaction or reflected in the Recent SEC Documents.
 
3.15 ERISA COMPLIANCE.
 
  (a) Schedule 3.15(a) contains a list of all "employee pension benefit plans"
(as defined in Section 3(2) of the Employee Retirement Income Security Act of
1974, as amended ("ERISA")) (sometimes referred to herein as "Pension Plans"),
"employee welfare benefit plans" (as defined in Section 3(1) of ERISA) and all
other benefit plans maintained or contributed to by the Company or any other
person or entity that, together with the Company, is treated as a single
employer under Section 414(b), (c), (m) or (o) of the Internal Revenue Code of
1986, as amended (the "Code") (the Company and each such other person or
entity, a "Commonly Controlled Entity"), for the benefit of any current or
former employees, officers or directors of the Company or dependents of any
such person (collectively, "Benefit Plans"). The Company has delivered or made
available to Investor or Newco, or their respective counsel, representatives
or advisors, true, complete and correct copies of (i) each Benefit Plan (or,
in the case of any unwritten Benefit Plans, descriptions thereof), (ii) the
most recent annual report on Form 5500 filed with the Internal Revenue Service
with respect to each Benefit Plan (if any such report was required), (iii) the
most recent summary plan description for each Benefit Plan for which such
summary plan description is required and (iv) each trust agreement and group
annuity contract relating to any Benefit Plan. None of the following have
occurred which could have a material adverse effect: (A) any failure to
administer any Benefit Plan in all material respects in accordance with its
terms, (B) any failure by the Company or any Subsidiary or any Benefit Plan to
comply in all material respects, or any failure of any Benefit Plan to be
operated and administered in all material respects, in accordance with the
applicable provisions of ERISA and the Code, (C) any "reportable event" or
"prohibited transaction" (as such terms are defined in ERISA and the Code),
(D) any termination of any Benefit Plan which results in a "reportable event,"
or (E) the consummation of the transactions entered into pursuant to this
Agreement if such transactions result in a "reportable event."
 
  (b) Except as disclosed in Schedule 3.15(b), all Pension Plans intended to
qualify under Section 401(a) of the Code have been the subject of
determination letters from the Internal Revenue Service to the effect that
such Pension Plans are qualified and exempt from Federal income taxes under
Section 401(a) and 501(a), respectively, of the Code, and no such
determination letter has been revoked nor has any such Pension Plan been
amended since the date of its most recent determination letter or application
therefor in any respect, and no event has occurred that would adversely affect
its qualification or materially increase its costs in a manner which would
constitute a material adverse effect. There have been no material violations
of ERISA or the Code with respect to the filing of applicable documents,
notices or reports (including, without limitation, annual reports filed on IRS
Form 5500) relating to any Benefit Plan maintained by the Company or any
Commonly Controlled Entity with any Governmental Authority or the furnishing
of such required documents to the participants or beneficiaries of such
Benefit Plans.
 
  (c) Neither the Company nor any Commonly Controlled Entity has within the
five year period immediately preceding the date hereof maintained, contributed
to or been obligated to contribute to any Benefit Plan that is subject to
Title IV of ERISA or Section 412 of the Code. Neither the Company nor any
Commonly Controlled Entity is required to contribute to any "multiemployer
plan" (as defined in Section 4001(a) (3) of ERISA) or
 
                                    A-I-17
<PAGE>
 
has withdrawn from any multiemployer plan where such withdrawal has resulted
or would result in any "withdrawal liability" (within the meaning of Section
4201 of ERISA) that has not been fully paid.
 
  (d) With respect to any Benefit Plan that is an employee welfare benefit
plan, except as disclosed in Schedule 3.15(d), (1) no such Benefit Plan is
funded through a "welfare benefits fund", as such term is defined in Section
419 (e) of the Code, (2) each such Benefit Plan that is a "group health plan",
as such term is defined in Section 5000 (b)(1) of the Code, complies
substantially with the applicable requirements of Section 4980B(f) of the Code
and (3) except as provided in writing in such plan, there are no
understandings, agreements or undertakings, written or oral, that would
prevent any such plan (including any such plan covering retirees or other
former employees) from being amended or terminated without material liability
to the Company or any Subsidiary on or at any time after the Effective Time.
Except as set forth in Schedule 3.15(d), no Benefit Plan that is a welfare
benefit plan provides for post-retirement medical or life insurance benefits
coverage to any current or former employee, officer, or director of the
Company or any dependent of any such individual except as may be required
under Section 4980B of the Code.
 
  (e) Except as set forth on Schedule 3.15(e) and except with respect to the
Company Stock Options, no employee or director of the Company will be entitled
to any additional compensation or benefits or any acceleration of the time of
payment or vesting of any compensation or benefits under any Benefit Plan as a
result of the transactions contemplated by this Agreement. It shall be assumed
for purposes of the preceding sentence that no payments will be received by,
or accelerated to, any such employee or director as a result of the
termination of such individual's employment/service relationship by the
Surviving Corporation after the Effective Time.
 
  (f) All contributions due and payable on or before the Closing Date in
respect of any Benefit Plan have been made in full and proper form, or
adequate accruals have been provided for in the financial statements contained
in the SEC Documents, in accordance with GAAP, for all other contributions or
amounts in respect of the Benefit Plans for periods ending on the Closing
Date, or, in the case of any contributory Benefit Plan, amounts have been
contributed to such Benefit Plan within the time prescribed by the Code,
ERISA, or any regulations thereunder or interpretations thereof by the
Internal Revenue Service or the Department of Labor.
 
  (g) As of the Closing Date, there are no actions, suits, disputes,
arbitrations or claims pending (other than routine claims for benefits) and
the Company has received no notice of any legal, administrative or other
proceedings or governmental investigations pending or, to the knowledge of the
Company and any Commonly Controlled Entity, threatened against any Benefit
Plan or against the assets of any Benefit Plan.
 
3.16 TAXES.
 
  (a) The Company has filed all tax returns and reports required to be filed
by it (which returns are true and complete in all material respects) and has
paid all taxes due and required to be paid by it. The most recent financial
statements contained in the SEC Documents reflect an adequate reserve for all
taxes payable by the Company or any Subsidiary for all taxable periods and
portions thereof through the date of such financial statements. No
deficiencies for any taxes have been proposed, asserted or assessed against
the Company or any Subsidiary that have not either been fully paid or
specifically reserved against in the financial statements included in the SEC
Documents, and, except as set forth on Schedule 3.16, no requests for waivers
of the time to assess any such taxes are pending. Except as disclosed in
Schedule 3.16, none of the income tax returns of the Company or any Subsidiary
have been or is currently being examined by the United States Internal Revenue
Service or any other Governmental Entity. Schedule 3.16 sets forth the periods
during which the Company's and its Subsidiaries' Consolidated Federal net
operating loss carryforwards (the "NOL Carryforwards") arose and the
expiration dates of the NOL Carryforwards, identifies which portions thereof
are currently limited under Section 382 of the Code or the "separate return
limitation year" ("SRLY") rules of the consolidated return regulations, and,
in the case of NOL Carryforwards currently limited under Section 382 of the
Code, the relevant Section 382 limitation (within the meaning of Section
382(b) (1) of the Code). As used in this Agreement, "taxes" shall mean all
Federal, state, local and foreign income, property, sales, payroll,
employment, excise, withholding and
 
                                    A-I-18
<PAGE>
 
other taxes, tariffs or other governmental charges in the nature of a tax as
well as any interest, penalties and additions to tax.
 
  (b) Except as set forth on Schedule 3.16, no amount that could be received
pursuant to the Benefit Plans or any executed and delivered agreements between
the Company or any Subsidiary and any officer, director or employee thereof in
effect as of the date hereof (whether in cash or property or the vesting of
property) as a result of any of the transactions contemplated by this
Agreement by any employee, officer or director of the Company or any
Subsidiary who is a "disqualified individual" (as such term is defined in
proposed Treasury Regulation Section 1.280G-1) under any employment,
severance, change-in-control or termination agreement, other compensation
arrangement or Benefit Plan currently in effect would either alone, or in
combination with any other amounts to be paid, be an "excess parachute
payment" (as such term is defined in Section 280G(b) (1) of the Code). No
officer, director or employee of the Company or any Subsidiary is entitled to
receive any additional payment from the Company, any Subsidiary, the Surviving
Corporation, or any other person referred to in Q&A 10 under proposed Treasury
Regulation Section 1.280G-1 (a "Parachute Gross-Up Payment") in the event that
the 20 per cent parachute excise tax of Section 4999(a) of the Code is imposed
on such person.
 
  (c) All Company Stock Options granted under any Stock Option Plan qualify,
under Section 162(m)(4) of the Code, as an exception from "applicable employee
remuneration," and as such, no deduction of the Company or any Subsidiary
relating to the Company Stock Options, shall be disallowed by reason of
Section 162(m) of the Code.
 
3.17 [Intentionally Omitted]
 
3.18 TITLE TO PROPERTIES; CONDITION OF ASSETS.
 
  (a) Except as set forth in Schedule 3.18, the Company and each Subsidiary
has good and marketable title to, or valid leasehold interests in, all its
material properties and assets except for such as are no longer used in the
conduct of its businesses or as have been disposed of in the ordinary course
of business. All such material assets and properties are free and clear of all
Liens other than those set forth in Schedule 3.18 and except for Liens that,
individually or in the aggregate, do not interfere with the ability of the
Company or any Subsidiary to conduct its business as currently conducted and
do not adversely affect the value of, or the ability to sell, in any material
respect, such assets and properties.
 
  (b) The properties and assets of the Company and its Subsidiaries are in
reasonably good repair and operating condition, ordinary wear and tear
excepted and are sufficient for the conduct of the business of the Company and
Subsidiaries as presently conducted.
 
  (c) Except as set forth in Schedule 3.18, the Company and each Subsidiary
has complied in all material respects with the terms of all material leases to

possession under all such material leases.
 
  (d) Neither the Company nor any Subsidiary owns any real property.

rights, trademarks, trademark rights, trade names, trade name rights, service
marks, service mark rights, copyrights and other proprietary intellectual
property rights and computer programs that are used in the conduct of the
business of the Company as now operated (collectively, "Intellectual Property
Rights"). Schedule 3.19 sets forth a description of all patents, trademarks
and copyrights and applications therefor owned by or licensed to the Company
that are used in the conduct of the business of the Company as now operated
(excluding
 
                                    A-I-19
<PAGE>
 
customary commercial software licenses). Except as set forth in Schedule 3.19,
no claims are pending or, to the knowledge of the Company, threatened that the
Company is, and to the knowledge of the Company, neither the Company nor any
Subsidiary is, infringing or otherwise adversely affecting the rights of any
person with regard to any Intellectual Property Right. To the knowledge of the
Company, except as set forth in Schedule 3.19, no person is infringing the
rights of the Company with respect to any Intellectual Property Right. The
Company has not licensed, or otherwise granted, to any third party, any rights
in or to any Intellectual Property Rights.
 
3.20 NON-COMPETE.
 
  Except for local vicinity covenants provided to certain healthcare customers
of the Company or a Subsidiary or as set forth in Schedule 3.20, neither the
Company nor any Subsidiary is subject to any agreement, covenant or
understanding that restricts the Company or any Subsidiary from entering or
conducting any line of business in any location at any time.

  The affirmative vote of the holders of a majority of the outstanding Shares

capital stock necessary to approve this Agreement and the Merger.
 
3.22 STATE TAKEOVER STATUTES.
 
  The Board of Directors of the Company has approved the Merger and this

Merger and this Agreement, the provisions of Section 203 of the DGCL to the
extent, if any, such Section is applicable to the Merger, this Agreement and
the transactions contemplated by this Agreement and the Stockholder Agreement.
No other state takeover statute or similar statute or regulation applies or

respective Affiliates (other than, after the Merger, the Company) will be
liable in connection with the execution of this Agreement by the Company or
the performance by the Company or its Subsidiaries of the Company's
obligations hereunder. The fees and expenses incurred and to be incurred by or

shareholders), shall not exceed, in the aggregate, the applicable amount set

employees, representatives and agents to, immediately cease any discussions or
negotiations with any parties other than Investor and Newco that may be
ongoing with respect to an Alternative Transaction (as hereinafter defined).
The Company shall not, shall cause each Subsidiary not to and shall not
authorize and shall direct and use reasonable efforts to cause its and its
Subsidiaries' officers, directors, employees and any investment banker,
financial advisor, attorney, accountant or other representative retained by it
not to, directly or indirectly, (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 may lead to an Alternative
Transaction or (ii) participate in any discussions or negotiations regarding
any proposed Alternative Transaction; provided, however, that if, during the

action is required by reason of the Board of
 
                                    A-I-26
<PAGE>
 
Directors' fiduciary duties to the Company's stockholders under applicable
law, the Company may (subject to compliance with Section 5.2(c)), during such
45 day period, in response to an unsolicited Third Party Proposal (as defined
herein), (A) furnish information with respect to the Company to the person

of the restrictions set forth in the preceding sentence by any director,
officer or employee of the Company or any Subsidiary or any investment banker,

any merger, consolidation, business combination, sale of substantially all the
assets, recapitalization, liquidation, dissolution or similar transaction
involving the Company or any Subsidiary, other than the transactions
contemplated by this Agreement and other than the acquisition of Shares
pursuant to the exercise of Company Stock Options or Warrants that are issued
and outstanding as of the date hereof or conversion of Series C Shares or
Series D Shares.
 
  (b) Neither the Board of Directors of the Company nor any Committee thereof
shall (i) withdraw or modify, the approval or recommendation by such Board of
Directors or such committee of this Agreement or the Merger, (ii) approve or
recommend, any Alternative Transaction or (iii) cause the Company to enter
into any letter of intent, agreement in principle, acquisition agreement or
other agreement, including any exclusivity agreement (an "Acquisition
Agreement") with respect to an Alternative Transaction unless the Board of
Directors of the Company shall have previously terminated this Agreement
pursuant to Section 8.1(g).
 
  (c) In addition to the obligations of the Company set forth in paragraphs
(a) and (b) of this Section 5.2, the Company shall immediately advise Investor
orally and in writing of any request for information or of any proposal or any
inquiry regarding any Alternative Transaction, the material terms and
conditions of such request, proposal or inquiry and the identity of the person
making such request, proposal or inquiry. The Company will keep Investor fully
informed of the status and details (including amendments or proposed
amendments) of any such request, proposal or inquiry.

Company's or any Subsidiary's tax liabilities or tax attributes.
 
5.4 OTHER ACTIONS.
 
  The Company shall not, and shall cause each Subsidiary not to, take or omit

expected to result in (a) any of the representations and warranties of the
Company set forth in this Agreement becoming untrue or inaccurate or (b) any
of the conditions set forth in Section 7.2 not being satisfied (subject to the
Company's right to take actions specifically permitted by Section 5.1, Section
5.2 or Section 8.1).

failure or failures to be true as of the date hereof of one or more of the

failures to be true are reasonably expected to have an aggregate negative
impact on the value of the Company and its Subsidiaries taken as a whole (a
"Negative Impact"), of $25 million or more, the Company shall pay to Investor
within 90 days of such termination (except for any termination pursuant to

all Expenses (as defined below).
 
  (c) If this Agreement is terminated (i) by Investor pursuant to Section

failures to be true as of the time of such termination one or more
representations and warranties, which representations and warranties were true

Expenses, and, if, within 180 days of such termination either an Alternative
Transaction shall be consummated or the Company shall enter into an
Acquisition Agreement providing for an Alternative Transaction (in either
event, the "Tail Condition") then the Company shall pay to Investor, upon the
closing of such transaction, if and whenever it occurs, $5,000,000.
 
  (d) If this Agreement is terminated by Investor pursuant to 8.1(b) as a
result of a failure of the condition set forth in Section 7.1(a) to be
satisfied or pursuant to Section 8.1(d), the Company shall pay to Investor all
Expenses, and if the Tail Condition is subsequently satisfied, shall pay to
Investor upon the closing of the relevant transaction, if and whenever it
occurs, $10,000,000; provided, however that no amounts whatsoever shall be
payable to Investor under this Section 6.9(d) if, at the Special Meeting or

Condition is subsequently satisfied, the Company shall pay to Investor, upon
the closing of the relevant transaction, if and whenever it occurs, $5,000,000
plus Expenses.
 
  (f) The Company acknowledges that the agreements contained in this Section
6.9 are an integral part of the transactions contemplated by this Agreement,
and that, without these agreements, Investor would not enter into this
Agreement. Accordingly, if the Company fails promptly to pay any amount due
pursuant to this Section 6.9, and, in order to obtain such payment, Investor
commences a suit which results in a judgment against the Company for the
amounts set forth in this Section 6.9, the Company shall pay to Investor all
costs and expenses (including attorneys' fees and expenses) in connection with
such suit, together with interest on such amounts (excluding Investor's costs
and expenses) at the prime rate of the Bankers Trust Company in effect on the
date

against Investor and/or Newco, Investor shall pay to the Company all costs and
expenses (including attorney's fees and expenses) in connection with such
suit. "Expenses" shall mean all reasonably documented out-of-pocket expenses
incurred by Investor and Newco in connection with this Agreement (including

has previously agreed in writing to increase such amount, the aggregate amount
of such Expenses shall not exceed (i) $3,000,000 if such termination occurs
prior to September 1, 1997, or (ii) $5,000,000 if such termination occurs
thereafter (the parties further agreeing that such amounts shall be reduced,
dollar for dollar, to the extent that the Company funds the expenses
(excluding for the services of the Company's professionals) of filing or
printing the Proxy Statement/Prospectus or the solicitation of proxies with
respect thereto).
 
  (g) After the Effective Time, the Company will pay to an Affiliate of
Investor a fee of $2,500,000 in connection with arranging the transactions
contemplated hereby (including the financings thereof) and an annual
management fee of $500,000 and agree to continue to receive financial advisory
services from such Affiliate on an ongoing basis with compensation to be
determined.
 
6.10 PUBLIC ANNOUNCEMENTS.

Company, on the other hand, will consult with each other before issuing, and
provide each other the opportunity to review and comment upon, any press
release or other public statements with respect to the transactions

                           TERMINATION AND AMENDMENT
 
8.1 TERMINATION.
 
  This Agreement may be terminated at any time prior to the Effective Time,
whether before or after approval of the terms of this Agreement by the
stockholders of the Company as follows:
 
  (a) By mutual written consent of Investor and the Company.
 
  (b) By either Investor or the Company if the Effective Time shall not have
occurred on or before December 31, 1997 (provided that the right to terminate
this Agreement under this Section 8.1(b) shall not be available to any party
whose failure to fulfill any obligation under this Agreement has been the
cause of or resulted in the failure of the Effective Time to occur on or
before such date).
 
  (c) By either Investor or the Company if any Governmental Entity shall have
issued an order, decree or ruling or taken any other action permanently
enjoining, restraining or otherwise prohibiting the Merger and such order,
decree or ruling or other action shall have become final and nonappealable.
 
  (d) By either Investor or the Company if the Company Stockholder Approval is
not obtained by reason of the failure to obtain the required vote upon a vote
held at a duly called meeting of stockholders or at any adjournment thereof.
 
  (e) By Investor, if (x) any of the representations and warranties of the
Company contained in this Agreement shall fail to be true and correct in any
material respect, in each case either as of when made or (except for
representations and warranties made only as of a specific date) have since
become, and at the time of termination remain, untrue in any material respect,
or (y) the Company shall have breached or failed to comply in any material
respect with any of its obligations under this Agreement (other than as a
result of a breach by the Investor or the Newco of any of their obligations
under this Agreement) and such breach of failure shall continue unremedied for
ten (10) days after the Company has received written notice from the Investor
or the Newco of the occurrence of such breach or failure; provided, however,
that in remedying any such breach or failure the Company shall not have spent
any money, incurred any liabilities or undertaken any obligations that,
individually or together with the breach or failure so remedied, would itself
constitute a breach of or failure to perform any representation, warranty or
covenant of this Agreement.
 
  (f) By Investor if there shall have occurred any material adverse change.
 
  (g) By either Investor or the Company if, prior to the Effective Time, (i)
the Board of Directors of the Company determines that a Third Party Proposal
for an Alternative Transaction constitutes a Superior Proposal (as defined
below), (ii) the Company promptly notifies Investor of its determination in
writing, which writing shall set forth the terms and conditions of the Third
Party Proposal and the identity of the person making the Third Party Proposal,
(iii) ten days have elapsed following receipt by Investor of such written
notice, (iv) during such ten day period the Company cooperates with Investor
with the intent of enabling, but not obligating, Investor and the Company to
agree to a modification of the terms and conditions of this Agreement so that
the transactions contemplated hereby may be effected, and (v) at the end of
such ten day period, the Board of Directors of the Company continues to
believe that such Third Party Proposal constitutes a Superior Proposal and the
Company pays to Investor the amount specified under Section 6.9(b) pursuant to
the terms thereof. For purposes of this Agreement, a "Superior Proposal" means
any Third Party Proposal to acquire, directly or indirectly at least 80% of
the Shares or all or substantially all of the assets of the Company; provided
that (i) the Board of Directors of the Company determines in its good faith
judgment (following consultation with and the receipt of the advice of the
Company's financial advisor) that such Third Party Proposal is on terms that
are more favorable to the Company's stockholders than the Merger (taking into
account all factors that the Board of Directors reasonably deems relevant,
including, in the judgment of the Board of Directors, the amount and form
 
                                    A-I-37
<PAGE>
 
of consideration to be received in respect of Shares, and the timing of, and
likelihood of closing such proposal and the relative value of any non-cash
consideration) and (ii) the Board of Directors of the Company determines in
its good faith judgment (following receipt of the written advice of its
outside counsel) that the failure to recommend or accept such Third Party
Proposal would violate the fiduciary duties of the Board of Directors of the
Company to stockholder under applicable law.
 
  (h) by the Company if (i) any of the representations and warranties of the
Investor or the Newco contained in this Agreement shall fail to be true and
correct in any material respect, in each case either when made or (except for
representations and warranties made only as of a specific date) have since
become, and at the time of termination remain, untrue in any material respect,
or (ii) Investor or the Newco shall have breached or failed to comply in any
material respect with any of its obligations under this Agreement (other than
as a result of a breach by the Company of any of its obligations under this
Agreement) and such breach or failure shall continue unremedied for ten (10)
days after the Investor or the Newco has received written notice from the
Company of the occurrence of such breach or failure; provided, however, that
in remedying any such breach or failure neither Investor nor Newco shall have
spent any money, incurred any liabilities or undertaken any obligations that,
individually or together with the breach or failure so remedied, would itself
constitute a breach of or failure to perform any representation, warranty or
covenant of this Agreement.
 
8.2 EFFECT OF TERMINATION.
 
  In the event of a termination of this Agreement by either the Company or
Investor as provided in Section 8.1, this Agreement shall forthwith become
void and there shall be no liability or obligation on the part of Investor,
Newco or the Company or their respective officers or directors, except with
respect to Section 4.6, the last sentence of Section 6.2, Section 6.9, Section
8.1, this Section 8.2 and Article IX; provided, however, that nothing herein
shall relieve any party for liability for any breach hereof.

or authorized by their respective Boards of Directors, may, to the extent
legally allowed, (i) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (ii) waive any
inaccuracies in the representations and warranties contained herein or in any
document delivered pursuant hereto or (iii) subject to Section 8.3, waive
compliance with any of the agreements or conditions contained herein. Any
agreement on the part of a party hereto to any such extension or waiver shall
be valid only if set forth in a written instrument signed on behalf of such
party. The failure of any party to this Agreement to assert any of its rights
under this Agreement or otherwise shall not constitute a waiver of those
rights.
 
8.5 AMENDMENT.
 
  To the extent permitted by applicable law, this Agreement may be amended by
action taken by or on behalf of the Boards of Directors of the Company,
Investor and Newco at any time before or after obtaining Company Stockholder
Approval. After obtaining Company Stockholder Approval, no amendment shall be
made which decreases the Merger Consideration or which materially and
adversely affects the rights of the Company's stockholders hereunder without
the approval of the stockholders of the Company. This Agreement may not be
amended except by an instrument in writing signed on behalf of all of the
parties.

                            ALLIANCE IMAGING, INC.
                            A DELAWARE CORPORATION

  THREE: The nature of the business or purposes to be conducted or promoted is
to engage in any lawful act or activity for which corporations may be

corporation shall have authority to issue is Ten Million Five Hundred Thousand
(10,500,000), consisting of:
 
    (i) Ten Million (10,000,000) shares of Common Stock (hereinafter referred
  to as "Common Stock") consisting of:
 
      (a) Nine Million Five Hundred Thousand (9,500,000) shares of voting
    common stock of the par value of one cent ($.01) (hereinafter referred
    to as "Voting Common"); and
 
      (b) Five Hundred Thousand (500,000) shares of non-voting common stock
    of the par value of one cent ($.01) (hereinafter referred to as "Non-
    Voting Common") each.

  value of one cent ($.01) (hereinafter referred to as the "Preferred

  A. Common Stock
 
  Except where otherwise provided by law, by this Amended and Restated
Certificate of Incorporation, or by resolution of the Board of Directors
pursuant to this Article FOUR, all shares of Common Stock shall be identical
in all respects and shall entitle the holders thereof to the same rights and
privileges, subject to the same qualifications, limitations and restrictions.
All holders of Common Stock issued and outstanding shall have and possess the
exclusive right to notice of stockholders' meetings.
 
  1. Voting Rights
 
  Except as otherwise required by applicable law or as set forth herein, the
holders of shares Non-Voting Common shall not be entitled to vote and the
holders of shares of Voting Common shall be entitled to vote as a single class
on all matters to be voted on by this corporation's shareholders. Except as

  FIVE: The following provisions are inserted for the management of the
business and the conduct of the affairs of this corporation, and for further
definition, limitation and regulation of the powers of this corporation and of
its directors and stockholders:
 
  A. The business and affairs of this corporation shall be managed by or under
the direction of the Board of Directors. In addition to the powers and
authority expressly conferred upon them by the DGCL or by this Amended and
Restated Certificate of Incorporation or the Bylaws of this corporation, the
directors are hereby empowered to exercise all such powers and do all such
acts and things as may be exercised or done by this corporation.
 
  B. The Board of Directors may adopt, amend or repeal the Bylaws of this
corporation.
 
  C. Election of directors need not be by written ballot.
 
  SIX: The officers of this corporation shall be chosen in such a manner,
shall hold their offices for such terms and shall carry out such duties as are
determined solely by the Board of Directors, subject to the right of the Board
of Directors to remove any officer or officers at any time with or without
cause.
 
  SEVEN: No director of this corporation shall be personally liable to this
corporation or its stockholders for monetary damages for any breach of
fiduciary duty by such a director as a director. Notwithstanding the foregoing
sentence, a director shall be liable to the extent provided by applicable law
(i) for any breach of the director's duty of loyalty to this corporation or
its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) pursuant
to Section 174 of the DGCL or (iv) for any transaction from which such
director derived an improper personal benefit. This Article SEVEN is also
contained in Article V, Section 5.1 of this corporation's Bylaws. No amendment
to or repeal of this Article SEVEN shall apply to or have any effect on the
liability or alleged liability of any director of this corporation for or with
respect to any acts or omissions of such director occurring prior to such
amendment or repeal. If the DGCL is amended hereafter to further eliminate or
limit the personal liability of directors, the liability of a director of this
corporation shall be limited or eliminated to the fullest extent permitted by
the DGCL, as amended.
 
  EIGHT: A. RIGHT TO INDEMNIFICATION. Each person who was or is made a party
to or is threatened to be made a party to or is involuntarily involved in any
action, suit or proceeding, whether civil, criminal, administrative or
investigative (a "Proceeding"), by reason of the fact that he or she is or was
a director or officer of this corporation, or is or was serving (during his or
her tenure as director and/or officer) at the request of this corporation as a
director, officer, employee or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, whether the basis of
such Proceeding is an alleged action or inaction in an official capacity as a
director or officer or in any other capacity while serving as a director or
officer, shall be indemnified and held harmless by this corporation to the
fullest extent authorized by the DGCL (or other applicable law), as the same
exists or may hereafter be amended, against all expense, liability and loss
(including attorneys' fees, judgments, fines, ERISA excise taxes or penalties
and amounts paid or to be paid in settlement) reasonably incurred or suffered
by such person in connection with such Proceeding. Such director or officer
shall have the right to be paid by this corporation for expenses incurred in
defending any such Proceeding in advance of its final disposition; provided,
however, that, if the DGCL (or other applicable law) requires, the payment of
 
                                A-II--Exhibit-2
<PAGE>
 
such expenses in advance of the final disposition of any such Proceeding shall
be made only upon receipt by this corporation of an undertaking by or on
behalf of such director or officer to repay all amounts so advanced if it
should be determined ultimately that he or she is not entitled to be
indemnified under this Article EIGHT or otherwise.
 
  B. RIGHT OF CLAIMANT TO BRING SUIT. If a claim under paragraph A of this
Article EIGHT is not paid in full by this corporation within ninety (90) days
after a written claim has been received by this corporation, the claimant may
at any time thereafter bring suit against this corporation to recover the
unpaid amount of the claim, together with interest thereon, and, if successful
in whole or in part, the claimant shall also be entitled to be paid the
expense of prosecuting such claim, including reasonable attorneys' fees
incurred in connection therewith. It shall be a defense to any such action
(other than an action brought to enforce a claim for expenses incurred in
defending any Proceeding in advance of its final disposition where the
required undertaking, if any is required, has been tendered to this
corporation) that the claimant has not met the standards of conduct which make
it permissible under the DGCL (or other applicable law) for this corporation
to indemnify the claimant for the amount claimed, but the burden of proving
such defense shall be on this corporation. Neither the failure of this
corporation (or of its full Board of Directors, its directors who are not
parties to the Proceeding with respect to which indemnification is claimed,
its stockholders, or independent legal counsel) to have made a determination
prior to the commencement of such action that indemnification of the claimant
is proper in the circumstances because he or she has met the applicable
standard of conduct set forth in the DGCL (or other applicable law), nor an
actual determination by any such person or persons that such claimant has not
met such applicable standard of conduct, shall be a defense to such action or
create a presumption that the claimant has not met the applicable standard of
conduct.
 
  C. NON-EXCLUSIVITY OF RIGHTS. The rights conferred by this Article EIGHT
shall not be exclusive of any other right which any director, officer,
representative, employee or other agent may have or hereafter acquire under
the DGCL or any other statute, or any provision contained in this
corporation's Amended and Restated Certificate of Incorporation or Bylaws, or
any agreement, or pursuant to a vote of stockholders or disinterested
directors, or otherwise.
 
  D. INSURANCE AND TRUST FUND. In furtherance and not in limitation of the
powers conferred by statute:
 
    (1) this corporation may purchase and maintain insurance on behalf of any
  person who is or was a director, officer, employee or agent of this
  corporation, or is serving at the request of this corporation as a
  director, officer, employee or agent of another corporation, partnership,
  joint venture, trust or other enterprise, against any liability asserted
  against him and incurred by him in any such capacity, or arising out of his
  status as such, whether or not this corporation would have the power to
  indemnify him against such liability under the provisions of law; and
 
    (2) this corporation may create a trust fund, grant a security interest
  and/or use other means (including, without limitation, letters of credit,
  surety bonds and/or other similar arrangements), as well as enter into
  contracts providing indemnification to the fullest extent permitted by law
  and including as part thereof provisions with respect to any or all of the
  foregoing, to ensure the payment of such amount as may become necessary to
  effect indemnification as provided therein, or elsewhere.
 
  E. INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THIS CORPORATION. This
corporation may, to the extent authorized from time to time by the Board of
Directors, grant rights to indemnification, including the right to be paid by
this corporation the expenses incurred in defending any Proceeding in advance
of its final disposition, to any employee or agent of this corporation to the
fullest extent of the provisions of this Section or otherwise with respect to
the indemnification and advancement of expenses of directors and officers of
this corporation.
 
 
                                A-II--Exhibit-3
<PAGE>
 
  F. AMENDMENT. This Article EIGHT is also contained in Article V, Sections
5.2 through 5.7 of this corporation's Bylaws. Any repeal or modification of

and agreements herein contained, and intending to be legally bound hereby, the
parties hereby agree as follows:

    Three Rivers Holding Corp. outstanding following the SMT/Three Rivers
    Merger and no subsequent stock splits, stock dividends or similar
    changes to the capital structure of Three Rivers Holding Corp.):
 
        Options attributable to rollover of SMT Options, with an average
      exercise price of $36.00 per share: 22,500 shares.
 
        Options attributable to new Three Rivers option plan, with an
      exercise price of $100.00 per share: not to exceed 35,000 shares.
 
    (d) The Investor covenants and agrees that if Three Rivers Acquisition

  purchase common stock, par value $.01, of Three Rivers Holding Corp. shall
  be convertible into options to purchase Alliance Shares only as set forth
  in this paragraph: each such option shall be convertible into an option to
  purchase 9.0909 Shares of Alliance and the exercise price for each such
  option to purchase Alliance Shares shall be equal to 0.11 times the
  exercise price of the corresponding option to purchase common stock, par
  value $.01, of Three Rivers Holding Corp. (such procedure assumes 335,600
  shares of Three Rivers Holding Corp. outstanding following the SMT/Three
  Rivers Merger and no subsequent stock splits, stock dividends or similar
  changes to the capital structure of Three Rivers Holding Corp.). If,
  following such conversion, any holder of such an option holds an option to
  purchase a fractional Alliance Share, the portion of the option
  representing the right to purchase a fractional Alliance Share shall be
  cancelled in exchange for the payment by the Company to the holder thereof
  of an amount equal to the Cash Merger Price times such fraction. The
  Investor shall make reasonable efforts to cause all outstanding options to
  purchase common stock, par value $.01, of Three Rivers Holding Corp. to be
  converted into options to purchase Alliance Shares on the basis described
  above.
 
  1.4 Sections 6.4(a) and (b) of the Agreement are amended and restated in
their entirety as follows:
 
    "(a) As soon as practicable following the date hereof but in no event
  later than the Effective Time, the Company (or, if appropriate, the Board
  of Directors of the Company or any committee administering the Stock Option
  Plans (as defined below)) shall (except as set forth in the last sentence
  of Section 6.4(b) below) take action, including by adopting resolutions or
  taking any other actions, so as to allow each outstanding option to
  purchase Shares (a "Company Stock Option") heretofore granted under any
  stock option, stock appreciation rights or stock purchase plan, program or
  arrangement of the Company (collectively, the "Stock Option Plans") and
  each outstanding warrant or other right or option to purchase Shares (a
  "Warrant") in each case outstanding immediately prior to the date hereof,
  whether or not then exercisable, either (i) shall be canceled at the
  Effective Time in exchange for an amount in cash, payable at the time of
  such cancellation, equal to the product of (x) the number of Shares subject
  to such Company Stock Option or Warrant immediately prior to the Effective
  Time and (y) the excess of the Cash Merger Price over the per Share
  exercise price of such Company Stock Option or Warrant (the "Net Amount")
  or (ii) shall be converted immediately prior to the Effective Time into the
  right solely to receive the Net Amount; provided, that no such cash payment
  has been made. The Company shall not make, or agree to make, any payment of
  any kind to any holder of a Company Stock Option or a Warrant (except for
  the payment described above) without the consent of Investor (which consent
  will not be unreasonably withheld).
 
    (b) All Stock Option Plans (except for the Company's 1991 Amended and
  Restated Stock Option Plan, as amended) shall be terminated as of the
  Effective Time and the provisions in any other Benefit Plan providing for
  the issuance, transfer or grant of any capital stock of the Company or any

  Time. The Company shall ensure that following the Effective Time, no holder
  of a Company Stock Option or Warrant or any participant in any Stock Option
  Plan shall have any right thereunder to acquire any capital stock of the
  Company, Investor or the Surviving Corporation, except as set forth in the
  next sentence or as agreed to otherwise by the Investor. Notwithstanding
  the foregoing, stock options representing the right to purchase Alliance
  Shares shall remain outstanding following the Effective Time as follows:
  (i) 150,581 of the Company Stock Options with an exercise price of $3.5625
  shall remain outstanding; (ii) 53,878 of the Company Stock Options with an
  exercise price of $0.4375 shall remain outstanding; and (iii) 56,122 of the
  Company Stock Options with an exercise price of $6.5625 shall remain

                                 "Investor") and the individuals listed on
                                 SCHEDULE A attached hereto (each, a
                                 "Stockholder" and, collectively, the

  Whereas, each Stockholder owns Company Stock Options or Warrants pursuant to
which such Stockholder has the right to acquire the number of shares of Common
Stock set forth opposite his or its name on SCHEDULE A attached hereto;

1. REPRESENTATIONS AND WARRANTIES OF EACH STOCKHOLDER.
 
  Each Stockholder hereby represents and warrants, severally and not jointly,
to the Investor as of the date hereof in respect of himself or itself as
follows:
 
    (A) Authority. The Stockholder has all requisite power and authority to
  enter into this Agreement and to consummate the transactions contemplated
  hereby. The execution, delivery and performance of this Agreement by the
  Stockholder, and the consummation of the transactions contemplated hereby,
  have been duly authorized by all necessary action on the part of the
  Stockholder. This Agreement has been duly executed and delivered by the
  Stockholder and constitutes a valid and binding obligation of the
  Stockholder enforceable against the Stockholder in accordance with its
  terms. Except for the expiration or termination of the waiting periods
  under the HSR Act, informational filings wit h the SEC, and compliance with
  any applicable state securities laws, the execution and delivery of this
  Agreement do not, and the consummation of the transactions contemplated
  hereby and compliance with the terms hereof will not, (i) conflict with, or
  result in any violation of, or default (with or without notice or lapse of
  time or both) under any provision of, any certificate or articles of
  incorporation, bylaws, certificate or articles of limited partnership,
  limited partnership agreement, trust agreement, loan or credit agreement,
  note, bond, mortgage, indenture, lease or other agreement, instrument,
  permit, concession, franchise, license, judgment, order, notice, decree,
  statute,

  Stockholder's property or assets, including the Subject Shares, (ii) to
  such Stockholder's knowledge, require any filing with, or permit,
  authorization, consent or approval of, or notice to, any federal, state or
  local government or any court, tribunal, administrative agency or
  commission or other governmental or regulatory authority or agency,
  domestic, foreign or supranational, or (iii) to such Stockholder's
  knowledge, violate any order, writ, injunction, decree, statute, rule or
  regulation applicable to the Stockholder or any of the Stockholder's
  properties or assets, including the Subject Shares. If the Stockholder is a
  natural person and is married, and the Stockholder's Subject Shares
  constitute community property or otherwise need spousal or other approval
  for this Agreement to be legal, valid and binding, this Agreement has been
  duly authorized, executed and delivered by, and constitutes a valid and
  binding agreement of, the Stockholder's spouse, enforceable against such
  spouse in accordance with its terms. No trust of which such Stockholder is
  a trustee requires the consent of any beneficiary to the execution and
  delivery of this Agreement or to the consummation of the transactions
  contemplated hereby.
 
    (B) The Subject Shares. The Stockholder is the record and beneficial
  owner of, and has good and marketable title to, the Subject Shares, Company

  into record ownership of such Stockholder as soon as practicable after the
  date hereof). The Stockholder does not own, of record or beneficially, any
  shares of capital stock of the Company or any Subsidiary or any option,
  warrants, rights or other securities convertible into or exercisable for
  shares of capital stock of the Company other than the Subject Shares,
  Company Stock Options and Warrants set forth opposite his or its name on
  Schedule A attached hereto, and other than the Company's Senior Notes which
  are convertible into shares of the Company's Series E Cumulative Redeemable
  Convertible Preferred Stock, par value $.01, none of which Senior Notes are
  so convertible prior to January 1, 1998. Except as set forth on Schedule

  retained by such Stockholder is entitled to any brokerage, finder's or
  other fee or commission in connection with the execution of this Agreement
  by such Stockholder or the performance by such Stockholder of its
  obligations hereunder (it being understood that Salomon Brothers Inc may be
  entitled to certain fees and expenses in connection with the transactions
  contemplated by the Merger Agreement, which fees and expenses shall be paid
  by the Company as set forth in the Merger Agreement).
 
2. OPTION TO PURCHASE SHARES.
 
  Each Stockholder hereby severally grants to the Investor an option to
purchase (the "Option"), in the Investor's sole discretion, all Subject Shares
set forth opposite such Stockholder's name on SCHEDULE A hereto, at a price
per Share equal to the Cash Merger Price or, in respect of a share of Series D
Stock, an amount in cash equal to the Cash Merger Price for each Share that
would have been received had such share of Series D Stock been converted into
Shares immediately prior to such purchase (the "Exercise Price"). The Option
shall be exercisable by the Investor, as to all Stockholders, at any time
prior to the termination of this Agreement, by delivery of a notice of
exercise to all Stockholders at the address of each Stockholder set forth in
SCHEDULE A. The Subject Shares shall be delivered (with any appropriate
executed stock power) by each Stockholder to Irell & Manella (the "Escrow

Stockholder of the purchase price payable therefor; upon such receipt the
Subject Shares shall be delivered by the Escrow Agent to Investor. Within ten

Stockholder a cash amount equal to the aggregate Exercise Price payable in
respect of such Stockholder's Subject Shares against delivery of certificates
representing such Subject Shares.

that is registered pursuant to the Securities Act of 1933, as amended (the

<PAGE>
 
                                                             November 10, 1997
 
Board of Directors
Alliance Imaging, Inc.
1065 Pacific Center Drive
Suite 200
Anaheim, CA 92806
 
Ladies and Gentlemen:
 
  You have requested our opinion as investment bankers as to the fairness,
from a financial point of view, to the holders of shares of common stock, par
value $.01 per share ("Company Common Stock"), of Alliance Imaging, Inc. (the
"Company") of the consideration to be received and retained by such
stockholders in connection with the proposed merger of the Company with
Newport Acquisition Corp. ("Newco"), a new corporation to be incorporated and
wholly owned by Newport Investment LLC ("Investor"), pursuant to the Agreement
and Plan of Merger (the "Agreement"), dated as of July 23, 1997, between
Investor and the Company, as amended through the date hereof.
 
  As more specifically set forth in the Agreement, and subject to the terms
and conditions thereof, Newco will merge with and into the Company (the
"Proposed Merger"), and all but 411,358 of the outstanding shares of Company
Common Stock (other than shares held by Investor, Newco or any of their
subsidiaries, shares held in treasury of the Company, or shares as to which
appraisal rights have been properly exercised under applicable law) will be
converted in the Proposed Merger into the right to receive $11.00 per Share in
cash and the remaining 411,358 outstanding Shares will remain outstanding as
stock of the Company upon consummation of the Proposed Merger ("Surviving
Common Stock") and will represent approximately 10.2% of the Surviving Common
Stock. Prior to the consummation of the Proposed Merger all shares of
convertible preferred stock of the Company will be redeemed or converted into
Company Common Stock, in which case such shares will be converted in the
Proposed Merger as set forth in the preceding sentence, and all options and
warrants of the Company shall be cashed out for, or converted into the right
to receive, an amount equal to the net value of $11.00 per share less the
exercise price of such option or warrant. The actual consideration received
and retained by each individual holder of Company Common Stock will depend on
whether such holder elects, and whether other holders elect, to retain Shares
and the application of pro rationing provisions contained in the Agreement. As
part of the Proposed Merger, the shares of capital stock of Newco will be
converted into an aggregate of 3,632,222 shares of Surviving Common Stock,
representing the approximately 89.8% of the remaining outstanding shares of
Surviving Common Stock.
 
  As you are aware, Salomon Brothers Inc has acted as financial advisor to the
Company in connection with the Proposed Merger and will receive a fee for our
services, a substantial portion of which is contingent upon consummation of
the Proposed Merger. In addition, as you are aware Salomon Brothers Inc may
propose to participate as syndication agent and as a member of the syndicate
providing senior debt financing, and to participate as co-manager in the
offering of high yield debt financing, to fund the cash payments to be made in
the Proposed Merger. Additionally, Salomon Brothers Inc has previously
rendered certain investment banking and financial advisory services to the
Company and certain affiliates of Investor, for which we have received
customary compensation. In addition, in the ordinary course of business, we
may actively trade the debt and equity securities of the Company for our own
account and for the accounts of customers and, accordingly, may at any time
hold a long or short position in such securities.
 
  In connection with rendering our opinion we have reviewed and analyzed, and
relied solely upon, the following: (i) the Agreement, including the amendments
thereto; (ii) certain publicly available information concerning the Company,
including the Annual Reports on Form 10-K of the Company for each of the years
in the three year period ended December 31, 1996 and the Quarterly Report on
Form 10-Q of the Company for the quarter ended September 30, 1997; (iii)
certain other internal information, primarily financial in nature, including
projections, concerning the business and operations of the Company furnished
to us by the Company for purposes of our analysis; (iv) certain publicly
available information concerning the trading of, and the trading market for,
 
                                      C-1
<PAGE>
 
the Company Common Stock; (v) certain publicly available information with
respect to certain other companies that we believe to be comparable to the
Company and the trading markets for certain of such other companies'
securities; and (vi) certain publicly available information concerning the
nature and terms of certain other transactions that we consider relevant to
our inquiry. We have also considered such other information, financial
studies, analyses, investigations and financial, economic and market criteria
that we deemed relevant. We have also discussed the foregoing, as well as
other matters we believe relevant to our inquiry, with the management of the
Company and officers of Investor.
 
  In our review and analysis and in arriving at our opinion, we have assumed
and relied upon the accuracy and completeness of all of the financial and
other information provided us or publicly available and have neither attempted
independently to verify nor assumed responsibility for verifying any of such
information. We have not conducted a physical inspection of any of the
properties or facilities of the Company, nor have we made or obtained or
assumed any responsibility for making or obtaining any independent evaluations
or appraisals of any of such properties or facilities. With respect to
projections, we have assumed that they have been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
management of the Company and officers of the Investor as to the future
financial performance of the Company and we express no view with respect to
such projections or the assumptions on which they were based. We have assumed
that the definitive Agreement will not, when executed, contain any terms or
conditions that differ materially from the terms and conditions contained in
the draft of such document we have reviewed, the conditions precedent to the
Proposed Merger contained in the Agreement will be satisfied and the Proposed
Merger will be consummated in accordance with the terms of the Agreement.
 
  In conducting our analysis and arriving at our opinion as expressed herein,
we have considered such financial and other factors as we have deemed
appropriate under the circumstances including, among others, the following:
(i) the historical and current financial position and results of operations of
the Company; (ii) the business prospects of the Company; (iii) the historical
and current market for the Company Common Stock and for the equity securities
of certain other companies that we believe to be comparable to the Company;
and (iv) the nature and terms of certain other acquisition transactions that
we believe to be relevant. We have also taken into account our assessment of
general economic, market and financial conditions as well as our experience in
connection with similar transactions and securities valuation generally. We
have also considered the process that resulted in the negotiation of the
Agreement, including discussions with other potential acquirors. Our opinion
necessarily is based upon conditions as they exist and can be evaluated on the
date hereof and we assume no responsibility to update or revise our opinion
based upon circumstances or events occurring after the date hereof. Our
opinion as expressed below does not constitute an opinion or imply any
conclusion as to the likely trading range for the Surviving Common Stock
following consummation of the Proposed Merger. Our opinion is, in any event,
limited to the fairness, from a financial point of view, of the consideration
to be received and retained by the holders of Company Common Stock in the
Proposed Merger and does not address the Company's underlying business
decision to effect the Proposed Merger or constitute a recommendation to any
holder of Company Common Stock as to how such holder should vote with respect
to the Proposed Merger, or what election such holder should make with respect
to the retention of such holder's shares of Company Common Stock.
 
  This opinion is intended solely for the benefit and use of the Company
(including its management and directors) in considering the transaction to
which it relates and may not be used for any other purpose or reproduced,
disseminated, quoted or referred to at any time, in any manner or for any
purpose, without the prior written consent of Salomon Brothers Inc.
 
  Based upon and subject to the foregoing, we are of the opinion as investment
bankers that the consideration to be received and retained by holders of
Company Common Stock in the Proposed Merger is fair, from a financial point of
view, to such stockholders.
 
                                          Very truly yours,
 
                                          SALOMON BROTHERS INC

<PAGE>
 
                                                                        ANNEX D
 
(S) 262. APPRAISAL RIGHTS.
 
  (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares
through the effective date of the merger or consolidation, who has otherwise
complied with subsection (d) of this section and who has neither voted in
favor of the merger or consolidation nor consented thereto in writing pursuant
to (S) 228 of this title shall be entitled to an appraisal by the Court of
Chancery of the fair value of his shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the work "stockholder" means a holder of record of stock in a stock
corporation and also a member of record of a nonstock corporation; the word
"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), 252, 254, 257, 258, 263 or 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 fights 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 holders 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 me terms or an agreement of merger or consolidation pursuant to (S)(S)
  251,252, 254, 257, 258, 263 or 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 at the
  effective date of the merger or consolidation will be either listed on a
  national securities exchange or designated as a national market system
  security on an interdealer quotation system by the National Association of
  Securities Dealers, Inc. or held of record by more than 2,000 holders;
 
    c. Cash in lieu of fractional shares or fractional depository receipts
  described in the foregoing subparagraphs a. and b. of this paragraph; or
 
    d. Any combination of the shares of stock, depository 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
 
                                      D-1
<PAGE>
 
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 fights are
  available pursuant to subsections (b) or (c) hereof that appraisal rights
  are available for any or all of the shares of the constituent corporations,
  and shall include in such notice a copy of this section. Each stockholder
  electing to demand the appraisal of his shares shall deliver to the
  corporation, before the taking of the vote on the merger or consolidation,
  a written demand for appraisal of his shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of his shares. A proxy or vote against the merger or
  consolidation shall not constitute such a demand. A stockholder electing to
  take such action must do so by a separate written demand as herein
  provided. Within 10 days after the effective date of such merger or
  consolidation, the surviving or resulting corporation shall notify each
  stockholder of each constituent corporation who has complied with this
  subsection and has not voted in favor of or consented to the merger or
  consolidation of the date that the merger or consolidation has become
  effective; or
 
    (2) If the merger or consolidation was approved pursuant to (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 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
 
                                      D-2
<PAGE>
 
entitled to appraisal right, may file a petition in the Court of Chancery
demanding a determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the
merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting
from the consolidation a statement setting forth the aggregate number of
shares not voted in favor of the merger or consolidation and with respect to
which demands for appraisal have been received and the aggregate number of
holders of such shares. Such written statement shall be mailed to the
stockholder within 10 days after his written request for such a statement is
received by the surviving or resulting corporation or within 10 days after
expiration of the period for delivery of demands for appraisal under
subsection (d) hereof, whichever is later.
 
  (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mall to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.
 
  (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates
to submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.
 
  (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court
may, in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on
the list filed by the surviving or resulting corporation pursuant to
subsection (f) of this section and who has submitted his certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that he is not entitled to
appraisal rights under this section.
 
  (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and in the case of holders
of shares represented by certificates upon the surrender to the corporation of
the certificates representing such stock. The Courts 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.
 
                                      D-3
<PAGE>
 
  (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
  (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection
(d) of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation);
provided, however, that if no petition for an appraisal shall be filed within
the time provided in subsection (e) of this section, or if such stockholder
shall deliver to the surviving or resulting corporation a written withdrawal
of his demand for an appraisal and an acceptance of the merger or
consolidation, either within 60 days after the effective date of the merger or
consolidation as provided in subsection (e) of this section or thereafter with
the written approval of the corporation, then the right of such stockholder to
an appraisal shall cease. Notwithstanding the foregoing, no appraisal
proceeding in the Court of Chancery shall be dismissed as to any stockholder
without the approval of the Court, and such approval may be conditioned upon
such terms as the Court deems just.
 
  (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.

                    INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Company's Restated Certificate of Incorporation, Bylaws and
indemnification agreements with the Company's officers and directors provide
for indemnification to the fullest extent permitted by the laws of the State
of Delaware against and with respect to threatened, pending or completed
actions, suits or proceedings arising from or alleged to arise from, a party's
actions or omissions as a director, officer, employee or agent of the Company
or of any other corporation, partnership, joint venture, trust or other
enterprise serving in such capacity at the request of the Company if such acts
or omissions occurred or were or are alleged to have occurred, while said
party was a director or officer of the Company; provided, however, the Company
shall not indemnify any director or officer in an action against the Company
unless the Company shall have consented to such action. Generally, under
Delaware law, indemnification will only be available where an officer or
director can establish that he/she acted in good faith and in a manner which
was reasonably believed to be in or not opposed to the best interests of the
Company.
 
  Section 145 of the Delaware Law provides that a corporation may indemnify a
director, officer, employee or agent made a party to an action by reason of
the fact that such person was a director, officer, employee or agent of the
corporation or was serving at the request of the corporation against expenses
actually incurred by such person in connection with such action if such person
acted in good faith and in a manner such person reasonably believed to be in,
or not opposed to, the best interest of the corporation with respect to any
criminal action, and had no reasonable cause to believe his conduct was
unlawful. Delaware Law does not permit a corporation to eliminate a director's
duty of care, and the provisions of the Company's Amended and Restated
Certificate of Incorporation have no effect on the availability of equitable
remedies such as injunction or rescission, based upon a director's breach of
the duty of care. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers or persons controlling
the Company pursuant to the foregoing provisions and agreements, the Company
has been informed that in the opinion of the Staff of the Securities and
Exchange Commission such indemnification is against policy as expressed in the
Securities Act and is therefore unenforceable.

ITEM 22. UNDERTAKINGS.
 
  The undersigned registrant hereby undertakes:
 
  (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
 
    (i) To include any prospectus required by section 10(a)(3) of the
  Securities Act of 1933;
 
                                     II-3
<PAGE>
 
    (ii) To reflect in the prospectus any facts or events arising after the
  effective date of the registration statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the
  registration statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range
  may be reflected in the form of prospectus filed with the Commission
  pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
  price represent no more than a 20% change in the maximum aggregate offering
  price set forth in the "Calculation of Registration Fee" table in the
  effective registration statement.
 
    (iii) To include any material information with respect to the plan of
  distribution not previously disclosed in the registration statement or nay
  material change to such information in the registration statement.
 
  (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.
 
  (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.
 
  (4) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the DGCL, the Certificate of Incorporation and By-laws,
or otherwise, the Registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities Act, and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  (5) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
 
  (6) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
  (7) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
  (8) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent
or given, the latest annual report, to security holders that is incorporated
by reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information
 
                                     II-4
<PAGE>
 
required to be presented by Article 3 of Regulation S-X is not set forth in
the prospectus, to deliver, or cause to be delivered to each person to whom
the prospectus is sent or given, the latest quarterly report that is
specifically incorporated by reference in the prospectus to provide such
interim financial information.
 
  (9) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c),
the issuer undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.
 
  (10) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (6) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.

                    Re: Registration Statement on Form S-4
 
Ladies and Gentlemen:
   
  We have examined the Registration Statement on Form S-4 to be filed by you
with the Securities and Exchange Commission on November 25, 1997 (the
"Registration Statement"), in connection with the registration of 411,358
shares (the "Shares") of the Common Stock, $.01 par value, of Alliance
Imaging, Inc. (the "Company") to be retained by Company shareholders in
connection with the recapitalization merger described therein (the "Merger").
As your counsel in connection with this transaction, we have examined the
proceedings proposed to be taken in connection with the retention of Shares in
connection with the Merger.     
   
  Based on these examinations, it is our opinion that upon completion of the
Merger, the Shares to be retained in the manner referred to in the
Registration Statement will be legally and validly issued, fully paid and non-
assessable.     
   
  We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name, whenever appearing in
the Registration Statement, including the Proxy Statement/Prospectus
constituting a part thereof and any amendments thereto.     
 
                                          Sincerely yours,

                        [IRELL & MANELLA LLP LETTERHEAD]

                                                               November 25, 1997

Alliance Imaging, Inc.
1065 North PacifiCenter Drive
Suite 200
Anaheim, California 92806

Gentlemen:

     We have acted as counsel for Alliance Imaging, Inc., a Delaware corporation
(the "Company"), in connection with the preparation, execution and delivery of
the Agreement and Plan of Merger, as amended to date (the "Merger Agreement"),
dated as of July 23, 1997, between Newport Investment LLC and the Company
(collectively, the "Parties"), and certain documents related or incidental
thereto and transactions to be effected thereunder. You have requested our
opinion concerning certain United States federal income tax ("U.S. federal
income tax") consequences of the transactions to be effected pursuant to the
Merger Agreement (the "Recapitalization"). Unless otherwise defined, capitalized
terms used herein have the meanings assigned to them in the Merger Agreement.

     In connection with this opinion, we have reviewed such documents as we have
found necessary or appropriate, including the Proxy Statement/Prospectus
included in the Registration Statement of which this opinion is an exhibit, the
Merger Agreement, and related documents pertaining to the Merger.  In expressing
our opinion, we are relying upon, and the opinion stated in this letter is
expressly based upon, the information and representations contained in the
documents provided to us by the Parties and the information and representations
provided in our discussions with representatives of the Parties.  We assume that
the documents and information provided to us present an accurate and complete
description of all of the facts relevant to the Merger.

     Based upon the foregoing, and assuming that the transactions contemplated
by the documents referred to above are consummated in accordance with their
terms and descriptions, we are of the opinion that, subject to all the
qualifications, limitations, the assumptions set forth herein, the material U.S.
federal income tax considerations generally applicable to the Recapitalization
are as set forth herein.

     Our opinion does not address all aspects of U.S. federal income tax that
may be applicable to Alliance stockholders in light of their status or personal
investment circumstances including, without limitation, the alternative minimum
tax. In particular, it does not address the U.S. federal income tax consequences
of the Recapitalization that are applicable to
<PAGE>
 
Alliance's stockholders subject to special U.S. federal income tax treatment
including (without limitation) persons who are not United States citizens or
residents, foreign persons, insurance companies, tax-exempt entities, retirement
plans, dealers in securities, persons who acquired their Alliance Common Stock
pursuant to the exercise of employee stock options or otherwise as compensation
and persons who hold their Alliance Common Stock as part of a "straddle,"
"hedge" or "conversion transaction." Moreover, our opinion does not take into
account the particular facts and circumstances of each stockholder's tax status
and attributes. As a result, the U.S. federal income tax consequences addressed
in our opinion may not apply to each of Alliance's stockholders. Our opinion
addresses neither the effect of any applicable state, local or foreign tax laws,
nor the effect of any federal tax laws other than those pertaining to the U.S.
federal income tax. Accordingly, we recommend that each stockholder consult its
own tax advisors regarding the specific tax consequences of the
recapitalization, including the application and effect of federal, state, local
and foreign tax laws and the possible effects of changes in federal and other
tax laws.

     Our opinion is based on certain customary assumptions regarding the factual
circumstances that will exist at the Recapitalization Effective Time.  If any of
these factual assumptions is inaccurate, the U.S. federal income tax
consequences of the Recapitalization could differ from those described herein.
Our opinion assumes that shares of Alliance Common Stock are held as capital
assets (within the meaning of Section 1221 of the Internal Revenue Code of 1986,
as amended (the "Code")) at the Recapitalization Effective Time.

     Characterization of the Recapitalization for U.S. Federal Income Tax
     --------------------------------------------------------------------
Purposes.  For U.S. federal income tax purposes, Newco will be disregarded as a
- --------                                                                       
transitory entity, and the merger of Newco with and into Alliance will be
treated as a sale of a portion of a stockholder's Alliance Common Stock to the
Investor in connection with the Recapitalization and as a redemption of a
portion of such stockholder's Alliance Common Stock by Alliance.  The number of
shares of Alliance Common Stock disposed of by a stockholder pursuant to the
Recapitalization that will be treated as sold in the Recapitalization will be
equal to the total number of shares surrendered by the stockholder multiplied by
(a) the amount of cash contributed to Newco by the Investor in exchange for
Newco stock (or otherwise) prior to the Recapitalization Effective Time (and not
attributable to expenses) divided by (b) the aggregate amount of cash paid to
stockholders pursuant to the Recapitalization.  The remainder of the
stockholder's shares of Alliance Common Stock disposed of in the
Recapitalization will be treated as redeemed by Alliance.

     Stockholders Receiving Cash.  As described more fully below, the U.S.
     ---------------------------                                          
federal income tax consequences of the Recapitalization with respect to a
particular stockholder who 

                                       2
<PAGE>
 
receives cash (including cash paid to dissenters and cash paid in lieu of
fractional shares) will depend upon, among other things, (i) the extent to which
a stockholder is deemed to have sold its Alliance Common Stock in the
Recapitalization or is deemed to have had its shares of Alliance Stock redeemed
by Alliance and (ii) whether the deemed redemption of a holder's Alliance Common
Stock by Alliance will qualify as a sale or exchange under Section 302 of the
Code. First, to the extent that a stockholder is considered to have sold
Alliance Common Stock in the Recapitalization, such stockholder will recognize
either capital gain or loss in an amount equal to the difference between (x) the
number of shares treated as sold in the Recapitalization multiplied by $11.00
and (y) the stockholder's adjusted tax basis in such shares. Such gain or loss
generally will be mid-term capital gain or loss, currently taxable at a maximum
rate of 28% (for individuals), in respect of Alliance Common Stock held by the
stockholder for more than one year and long-term capital gain or loss, currently
taxable at a maximum rate of 20% (for individuals; which rate may be 10% for
individuals in lower tax brackets), in respect of Alliance Common Stock held by
the stockholder for more than 18 months. Second, a stockholder also will
recognize either capital gain or loss equal to the difference between (x) the
number of shares treated as redeemed by Alliance multiplied by $11.00 and (y)
the stockholder's adjusted tax basis in such Common Stock, if such redemption is
treated as a sale or exchange under Section 302 of the Code with respect to such
stockholder. Such gain or loss will also generally be mid-term or long-term
capital gain or loss in respect of Alliance Common Stock held by an individual
stockholder for more than one year or 18 months, respectively.

     Under Section 302 of the Code, a redemption of Alliance Common Stock
pursuant to the Recapitalization will, as a general rule, be treated as a sale
or exchange if the redemption (a) results in a "complete termination" of the
stockholder's interest in Alliance, (b) is "substantially disproportionate" with
respect to the stockholder or (c) is "not essentially equivalent to a dividend"
with respect to the stockholder.  In determining whether any of these Section
302 tests is satisfied, stockholders must take into account not only Alliance
Common Stock that they actually own, but also any Alliance Common Stock they are
"deemed" to own under the constructive ownership rules set forth in Section 318
of the Code.  Pursuant to these constructive ownership rules, a stockholder will
be deemed to own stock that is actually or constructively owned by certain
members of his or her family (spouse, children, grandchildren and parents) and
other related parties including, for example, certain entities in which such
stockholder has a direct or indirect interest (including partnerships, estates,
trusts and corporations), as well as shares of stock that such stockholder (or a
related person) has the right to acquire upon exercise of an option or
conversion right. In addition, if a stockholder lives in a community property
state, the community property laws of that

                                       3
<PAGE>
 
state may have an effect on the constructive ownership rules. Section 302(c)(2)
of the Code provides certain exceptions to the family attribution rules for the
purpose of determining a "complete termination." If a stockholder intends to
rely upon these exceptions, the stockholder must file a "waiver of family
attribution" statement with his tax return and must comply with certain other
requirements set forth in the Code and the Income Tax Regulations promulgated
thereunder (the "Regulations").

     The redemption of a stockholder's shares of Alliance Common Stock will
result in a "complete termination" of a stockholder's interest in Alliance if
either (a) all Alliance Common Stock actually and constructively owned by the
stockholder is redeemed or sold pursuant to the Recapitalization or (b) all of
the Alliance Common Stock actually owned by the stockholder is redeemed or sold
pursuant to the Recapitalization and the stockholder is eligible to waive, and
does effectively waive in accordance with Section 302(c) of the Code,
attribution of all Alliance Common Stock which otherwise would be considered to
be constructively owned by such stockholder.  Such waiver of attribution applies
only to Alliance Common Stock that would be attributed to a stockholder from
members of such stockholder's family.

     The redemption of a stockholder's Alliance Common Stock will be
"substantially disproportionate" with respect to such stockholder if the
percentage of Alliance Common Stock actually and constructively owned by such
stockholder immediately following the Recapitalization is less than 80% of the
percentage of Alliance Common Stock actually and constructively owned by such
stockholder immediately prior to the Recapitalization and is less than 50% of
the total Alliance Common Stock outstanding after the Recapitalization.  Waiver
of family attribution is not available in applying the "substantially
disproportionate" test.

     Even if the redemption of a stockholder's Alliance Common Stock fails to
satisfy the "complete termination" test and the "substantially disproportionate"
test described above, the redemption of a stockholder's Alliance Common Stock
may nevertheless satisfy the "not essentially equivalent to a dividend" test if
the stockholder's redemption of Alliance Common Stock pursuant to the
Recapitalization results in a "meaningful reduction" in such stockholder's
proportionate Alliance Common Stock interest in Alliance.  Whether the receipt
of cash by a stockholder will be considered "not essentially equivalent to a
dividend" will depend upon such stockholder's particular facts and
circumstances. No general guidelines indicating the facts and circumstances
under which a redemption will be considered to produce a meaningful reduction in
proportionate interest have been provided by the courts or issued by the
Internal Revenue Service (the "Service"). However, the Service has clearly
stated its position that if no reduction in percentage interest occurs, 

                                       4
<PAGE>
 
none of the Section 302 tests will be satisfied. Waiver of family attribution is
not available in the context of the "not essentially equivalent to a dividend"
test.

     In assessing whether the redemption of a stockholder's shares of Alliance
Common Stock satisfies the "substantially disproportionate" test or the "not
essentially equivalent to a dividend" test described above, it should be
emphasized that the Recapitalization will substantially reduce the number of
outstanding shares of Alliance Common Stock.  As a result, if a stockholder
elects to retain a portion of its Alliance Common Stock, the stockholder's
percentage interest in Alliance Common Stock of Alliance may not be reduced even
if the stockholder receives cash for a substantial portion of its Alliance
Common Stock.

     With respect to shares of Alliance Common Stock treated as redeemed, if a
stockholder cannot satisfy any of the three tests described above and to the
extent Alliance has sufficient current and/or accumulated earnings and profits,
such stockholder will be treated as having received a dividend which will be
includible in gross income (and treated as ordinary income) in an amount equal
to that portion of the cash received with respect to the deemed redemption of
the Alliance Common Stock.  In addition, the stockholder's basis in such
Alliance Common Stock disposed of will not offset the amount of cash received,
but instead will be reallocated to shares of Alliance Common Stock still held by
such stockholder or, although the matter is not free from doubt, if no shares
are actually owned, reallocated to those shares constructively owned, under
certain circumstances.  To the extent that a portion of the cash received with
respect to the deemed redemption of the shares of Alliance Common Stock exceeds
the current and/or accumulated earnings and profits of Alliance attributable to
the retained and (deemed) redeemed shares of Alliance Common Stock, such excess
will first be treated as a non-taxable return of capital to the extent of the
basis attributable to such retained and (deemed) redeemed shares and then as a
capital gain.  Such capital gain will be short-term, mid-term or long-term
depending on the holding period for the retained shares.  If a stockholder
acquired shares of Alliance Common Stock at different times and/or at different
prices, the application of the rules for basis reduction, gain recognition and
type of capital gain is unclear.

     To the extent that one of the three tests described above is satisfied, a
stockholder will be treated as having sold its Alliance Common Stock, which will
generally give rise to mid-term or long-term capital gain or loss in respect of
Alliance Common Stock held by the individual stockholder for more than 12 or 18
months, respectively. While the marginal tax rates for dividends and capital
gains are the same for corporate stockholders, the current maximum U.S. federal
income tax rate on ordinary income and short-term capital gains of individuals
(39.6%) exceeds the maximum tax rate on mid-term capital gains

                                       5
<PAGE>
 
(28%) and on long-term capital gains (20%). In addition, capital gain can
generally be offset by any capital loss that an individual stockholder may have
incurred, whereas capital loss of a corporation may not offset ordinary income,
and capital loss of an individual can only offset ordinary income to the extent
of $3,000 per year (subject to carryover).

     In the case of a corporate stockholder, if the cash paid is treated as a
dividend, such dividend income may be eligible for the 70% (or 80% if more than
20% of the vote and value of Alliance Common Stock is held by such corporate
stockholder) dividends-received deduction.  The dividends-received deduction is
subject to certain limitations, and may not be available if the corporate
stockholder does not satisfy certain holding period requirements with respect to
Alliance Common Stock or if Alliance Common Stock is treated as "debt financed
portfolio Stock" within the meaning of Code Section 246A(c).  Additionally, if a
dividends-received deduction is available, the dividend may be treated as an
"extraordinary dividend" under Section 1059(a) of the Code, in which case a
corporate stockholder's adjusted tax basis in Alliance Common Stock retained by
such stockholder would be reduced, but not below zero, by the amount of the
nontaxed portion of such dividend.  Any amount of the nontaxed portion of the
dividend in excess of the corporate stockholder's adjusted tax basis generally
will be subject to taxation when the extraordinary dividend is received.

     Stockholders Retaining Alliance Common Stock and Receiving No Cash.  The
     ------------------------------------------------------------------      
Recapitalization will have no U.S. federal income tax consequences for
stockholders who retain their Alliance Common Stock and receive no cash.
Accordingly, a stockholder will not recognize any gain or loss on any Alliance
Common Stock retained by such stockholder.

     Stockholders Retaining a Portion of their Alliance Common Stock and
     -------------------------------------------------------------------
Receiving Cash.  To the extent that a stockholder elects to retain a portion of
- --------------                                                                 
its Alliance Common Stock and exchange a portion of its Alliance Common Stock
for cash and does receive cash, or to the extent a stockholder receives cash in
exchange for some portion of its Alliance Common Stock as a result of proration,
the tax treatment of the stockholder's receipt of such cash will be the same as
set forth above under "Stockholders Receiving Cash."

     Information Reporting and Backup Withholding.  Alliance must report
     --------------------------------------------                       
annually to the Service and to each stockholder the amount of dividends paid to
such stockholder and the backup withholding tax, if any, withheld with respect
to such dividends. Backup withholding is a withholding tax imposed at the rate
of 31% on certain payments to persons that fail to furnish certain information
under the United States information reporting requirements. Payment of the
proceeds of a sale of Alliance Common Stock by or through a United States office
of a broker is subject to both backup 

                                       6
<PAGE>
 
withholding and information reporting unless the beneficial owner establishes an
exemption. Any amounts withheld under the backup withholding rules may be
allowed as a refund or a credit against the holder's U.S. federal income tax
liability provided the required information is furnished to the Service.

     In expressing our opinion, we mean that, if the Service were to assert a
position contrary to the conclusions described herein, the conclusions described
herein, if properly presented to a court, should prevail.  The Service may take
positions contrary to the conclusions expressed herein, and there is a risk that
such positions of the Service might ultimately be sustained by the courts.  Our
opinion is not binding on the Service or the courts, and should not be construed
as a guarantee of ultimate results.

     We hereby consent to the use of the name of our firm under the caption
"Certain Tax Consequences of the Recapitalization" and "Legal Matters" in the
Registration Statement and the related Proxy Statement/Prospectus and consent to
the filing of this opinion as an exhibit to the Registration Statement.

     In giving the above consents, we do not thereby admit that we come within
the category of persons whose consent is required under Section 7 of the
Securities Act or the rules and regulations of the Commission promulgated
thereunder.

     The opinion set forth herein is based on our interpretation of the
applicable provisions of the Code, the Regulations and administrative and
judicial interpretations of the Code and the Regulations, all as currently in
effect.  Any and all of these could change, and any such change could require a
conclusion or conclusions different from the opinion expressed herein.  We do
not undertake to advise you as to any future changes in the Code, the
Regulations, or administrative or judicial interpretations of either that may
affect our opinion unless we are specifically retained to do so.
