                                  ----------
 
  Alliance Imaging, Inc. ("Alliance" or the "Company") is offering $165,000,000
(the "Offering") aggregate principal amount of its    % Senior Subordinated
Notes due 2005 (the "Notes"). The Offering is part of the financing that will
be used to consummate the recapitalization of Alliance (the
"Recapitalization"). The Recapitalization will be effected pursuant to an
Agreement and Plan of Merger (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 upon the completion of the Offering, with Alliance as the
surviving corporation. The consummation of the Offering, the Recapitalization
and the transactions contemplated thereby will be concurrent, and the Offering
is conditioned upon the other Transactions (as defined).
 
  Interest on the Notes will be payable semi-annually on each and , commencing
, 1998, at the rate of    % per annum. The Notes will be redeemable, in whole
or in part, at the option of the Company on or after , 2001 at the redemption
prices set forth herein plus accrued interest to the date of redemption. In
addition, on or prior to , 2000, the Company may, at its option, redeem up to
40% of the aggregate principal amount of the Notes with the net cash proceeds
of one or more Equity Offerings (as defined), at the redemption price set forth
herein plus accrued interest to the date of redemption; provided, however, that
after any such redemption, 60% of the aggregate principal amount of the Notes
issued must remain outstanding.
 
  The Notes will be general unsecured obligations of the Company and will be
subordinated in right of payment to all Senior Debt (as defined) of the
Company, including indebtedness under the Credit Agreement (as defined). The
Notes will be unconditionally guaranteed (the "Guarantees") on a senior
subordinated basis by substantially all of Alliance's domestic subsidiaries
(the "Guarantors"). The Guarantees will be general unsecured obligations of the
Guarantors and will be subordinated in right of payment to all Guarantor Senior
Debt (as defined) of the Guarantors. As of September 30, 1997, after giving pro
forma effect to the Transactions, the Company would have had approximately
$56.9 million of Senior Debt outstanding (excluding unused commitments of $75.0
million under the Credit Agreement).
 
  Upon a Change of Control (as defined), each holder will have the right to
require the Company to repurchase such holder's Notes at a price equal to 101%
of their principal amount plus accrued interest to the date of repurchase.
There can be no assurance that the Company will have the financial ability or
will be permitted by the Credit Agreement to repurchase the Notes. See "Risk
Factors--Repurchase of Notes upon a Change of Control." In addition, the
Company will be obligated to offer to repurchase the Notes at 100% of their
principal amount plus accrued interest to the date of repurchase in the event
of certain asset sales.
 
  There is no existing market for the Notes, and there can be no assurance as
to the liquidity of any markets that may develop for the Notes, the ability of
the holders of the Notes to sell their Notes or the price at which such holders
would be able to sell their Notes. The Company does not intend to apply for
listing of the Notes on any securities exchange. See "Risk Factors--Absence of
Public Market."

made to, and this summary is qualified in its entirety by, the more detailed
information contained elsewhere in this Prospectus and in the documents

                                  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.
 
  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 (as defined
herein) 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.
 
                               INDUSTRY OVERVIEW
 
  The diagnostic imaging industry, which involves the use of non-surgical
techniques to generate representations of internal structures and organs on
film or video, generates annual revenues in excess of $50 billion in the United
States, or 5% to 6% of total health care spending. MRI services, which involve
the use of high strength magnetic fields to produce cross-sectional images of
the anatomy, constituted approximately $6 to $7 billion of the diagnostic
imaging industry in 1996. The approximately 4,000 MRI systems in the United
States include approximately 2,400 hospital owned systems, 1,000 independent
fixed site systems and 600 mobile systems.
 
  MRI facilitates the early diagnosis of diseases and disorders, often
minimizing the cost and amount of care needed and frequently eliminating the
need for invasive diagnostic procedures. MRI is the preferred imaging modality
for the brain, the spine and soft tissue because it produces a superior image
and does not expose patients to ionizing radiation. As a result of the cost
efficiency and clinical effectiveness of MRI, hospitals and other health care
providers are facing competitive pressures to provide MRI technology and
related services despite budgetary limitations. Increasingly, such providers
are utilizing third parties such as the Company to provide the necessary
imaging systems and related services to avoid substantial equipment and
operating costs. Mobile MRI operators employ systems housed in specially
designed trailers and typically enter into long-term contracts to provide a
specified schedule 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 system utilization.
 
                                       1
<PAGE>
 
 
  The MRI services industry has experienced substantial growth in demand as
measured by total scan volumes, which 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. Growth in the MRI industry is attributable to increased
physician acceptance, 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.
 
  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 total MRI systems in the United
States.
 
                             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 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.
 
                                       2
<PAGE>
 
 
  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 days sales outstanding
("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 Transactions 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.
 
  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.
 
                                       3
<PAGE>
 
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 new 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 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 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 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, 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.

                                THE TRANSACTIONS
 
  In connection with the completion of the Offering, Alliance intends to
consummate the Recapitalization pursuant to the Recapitalization Merger
Agreement. In connection with the Transactions, the Company expects to enter
into an agreement (the "Credit Agreement") providing for a $50 million term
loan facility (the "Term Loan Facility") and a $75 million revolving loan
facility (the "Revolving Loan Facility"), which will be available for the
Company's working capital requirements and to finance acquisitions.
 
  In connection with the Transactions, Apollo will invest $37.3 million and BT
Capital Partners, an affiliate of BT Alex. Brown Incorporated (the "BT
Investor"), will invest $2.7 million of cash equity in the Company
(collectively, the "Equity Investment"). Immediately following consummation of
the Transactions, Apollo will own approximately 84% of the outstanding common
stock of the Company (approximately 74% on a fully diluted basis) and the BT
Investor will own approximately 6% of the outstanding common stock of the
Company (approximately 5% on a fully diluted basis). In addition, Apollo and
the BT Investor will purchase $14.1 million and $0.9 million, respectively, of
the Company's Series F Preferred Stock. As part of the Recapitalization, common
stock of Alliance with a value of approximately $4.5 million will be retained
by existing stockholders of the Company, representing approximately 10% of the
outstanding common stock of the Company. In addition, immediately following
consummation of the Transactions, through a combination of (i) the continuation
of existing options (having an option value of approximately $0.5 million) to
purchase common stock of Alliance and (ii) the issuance of options pursuant to
the Company's new option plan (the "New Option Plan"), management will own in
excess of 11% of the equity of the Company on a fully-diluted basis.
 
  The Offering, the Recapitalization, the Equity Investment and the related
borrowings under the Credit Agreement are collectively referred to herein as
the "Transactions." The consummation of the Transactions will be concurrent,
and the Offering is conditioned upon the other Transactions. The approximate
sources and uses 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):

(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.

                                 RISK FACTORS
 
  Prospective purchasers of the Notes should consider carefully the
information set forth below as well as all other information set forth in this
Prospectus, in evaluating an investment in the Notes.
 
SUBSTANTIAL LEVERAGE
 
  After giving effect to the Transactions, the Company's consolidated
indebtedness will be approximately $221.9 million. This high level of
indebtedness in comparison to historical indebtedness may reduce the
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 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 Transactions 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.
 
RESTRICTIVE DEBT COVENANTS
 
  The Indenture will contain certain covenants that, among other things, limit
the ability of the Company and its Restricted Subsidiaries to incur additional
indebtedness, incur liens, pay dividends or make certain other restricted
payments, consummate certain asset sales, enter into certain transactions with
affiliates, incur indebtedness that is subordinate in right of payment to any
Senior Debt and senior in right of payment to the Notes, merge or consolidate
with any other person or sell, assign, transfer, lease, convey or otherwise
dispose of all of or substantially all of the assets of the Company and impose
restrictions on the ability of a Restricted Subsidiary to pay certain
dividends or make certain payments to the Company. See "Description of the
Notes--Certain Covenants." In addition, 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
 
                                      10
<PAGE>
 
ratio; (ii) a 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 "Description of the Credit Agreement."
 
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 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.
 
                                      11
<PAGE>
 
  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."
 
  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.
 
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,
 
                                      12
<PAGE>
 
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.
 
SUBORDINATION OF NOTES AND THE GUARANTEES
 
  The Notes and the Guarantees will be unsecured and subordinated to the prior
payment in full of all Senior Debt of the Company and all Guarantor Senior
Debt of the Guarantors, respectively. As of September 30, 1997, on a pro forma
basis after giving effect to the Transactions, the aggregate outstanding
principal amount of all Senior Debt would have been approximately $56.9
million. In the event of a bankruptcy, liquidation or reorganization of the
Company, the assets of the Company or the Guarantors will be available to pay
obligations on the Notes only after all Senior Debt of the Company or all
Guarantor Senior Debt of the Guarantors, as the case may be, has been paid in
full, and there may not be sufficient assets remaining to pay amounts due on
any or all of the Notes. In addition, the Company may not pay principal or
premium, if any, or interest on the Notes if any Senior Debt is not paid when
due or any other default on any Senior Debt occurs and the maturity of such
Senior Debt is accelerated in accordance with its terms, unless, in either
case, such amount has been paid in full or the default has been cured or
waived and such acceleration has been rescinded. In addition, if any default
occurs with respect to certain Senior Debt and certain other conditions are
satisfied, the Company may not make any payments on the Notes for a designated
period of time. Finally, if any judicial proceeding is pending with respect to
any such default in payment on any Senior Debt or other default with respect
to certain Senior Debt, or if the maturity of the Notes is accelerated because
of a default under the Indenture and such default constitutes a default with
respect to any Senior Debt, the Company may not make any payment on the Notes.
See "Description of the Notes--Subordination."
 
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 Guarantees) 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.
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
 
                                      13
<PAGE>
 
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.
 
REPURCHASE OF NOTES UPON A CHANGE OF CONTROL
 
  In the event of a Change of Control, the Company will be required to offer
to repurchase all of the outstanding Notes at a purchase price equal to 101%
of the aggregate principal amount thereof, plus accrued and unpaid interest,
if any, to the repurchase date. The Credit Agreement will prohibit the
repurchase of the Notes upon a Change of Control unless and until the
indebtedness under the Credit Agreement is repaid in full. There can be no
assurance that the Company will have sufficient funds available or will be
permitted by the Credit Agreement and any other indebtedness to repurchase the
Notes upon the occurrence of a Change of Control. The Change of Control
purchase feature of the Notes may in certain circumstances make more difficult
or discourage a takeover of the Company and, thus, the removal of incumbent
management. See "Description of the Notes--Change of Control."
 
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 employment agreements and an agreement not to compete with Alliance which
will become effective at the effective time of the Recapitalization. See
"Management--Employment and Related Agreements."
 
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.
 
CONTROL BY APOLLO; POTENTIAL CONFLICTS OF INTEREST
 
  Upon consummation of the Transactions, Apollo will own approximately 84% of
the outstanding common stock of the Company (approximately 74% on a fully
diluted basis). Accordingly, Apollo and its general partner will control the
Company 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 the
Company's certificate of incorporation and approving mergers or sales of
substantially all of the Company'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.
 
ABSENCE OF PUBLIC MARKET
 
  The Notes are a new issue of securities which have no established trading
market. It is expected that the Notes will be sold to a limited number of
investors. The Company has been advised by the Underwriters that they intend
to make a market in the Notes after the consummation of this Offering;
however, the Underwriters are not obligated to do so, and any such market-
making, if commenced, may be terminated at any time without notice. No
assurance can be given as to the liquidity of the trading market, if any, that
may develop for the Notes.

                               THE TRANSACTIONS
 
  In connection with the completion of the Offering, Alliance intends to
consummate the Recapitalization pursuant to the Recapitalization Merger
Agreement. In connection with the Transactions, the Company expects to enter
into the Credit Agreement providing for the $50 million Term Loan Facility and
the $75 million Revolving Loan Facility which will be available to provide for
the Company's working capital requirements and to finance acquisitions.
 
  In connection with the Transactions, Apollo will invest $37.3 million and
the BT Investor will invest $2.7 million of cash equity in the Company.
Immediately following consummation of the Transactions, Apollo will own
approximately 84% of the outstanding common stock of the Company
(approximately 74% on a fully diluted basis) and the BT Investor will own
approximately 6% of the outstanding common stock of the Company (approximately
5% on a dully diluted basis). As part of the Recapitalization, common stock of
Alliance with a value of approximately $4.5 million will be retained by
existing stockholders of the Company, representing approximately 10% of the
outstanding common stock of the Company. In addition, immediately following
consummation of the Transactions, through a combination of (i) the
continuation of existing options (having an option value of approximately $0.5
million) to purchase common stock of Alliance and (ii) the issuance of options
pursuant to the Company's New Option Plan, management will own in excess of
11% of the equity of the Company on a fully-diluted basis.
 
  Also in connection with the Transactions, Apollo and the BT Investor will
purchase $14.1 million and $0.9 million, respectively, of the Company's Series
F Preferred Stock. The Series F Preferred Stock has a dividend rate of 13.50%
per annum, payable quarterly in arrears, is redeemable at the option of the
Company at stated redemption premiums and matures in 2007. Dividends on the
Series F Preferred Stock are payable in kind for the first five years and
thereafter in cash, subject to compliance with the Company's then-existing
debt agreements. Apollo and the BT Investor will receive financing fees equal
to 4% of their respective investments in the Series F Preferred Stock.
 
  A more detailed description of the Transactions is contained in Alliance's
registration statement on Form S-4 (File No. 333-33787). See "Available
Information."

                                USE OF PROCEEDS
 
  The net proceeds of the Company from the sale of the Notes are estimated to
be $160.0 million. The Company intends to use the net proceeds, together with
borrowings under the Credit Agreement, to fund the Transactions, to repay
certain outstanding indebtedness and to pay fees and expenses relating to the
Transactions. The indebtedness being repaid consists of approximately $76.2
million (comprising Alliance's senior notes and debt incurred to purchase
equipment) that bears interest at rates of 8.0% to 11.4% per annum and matures
from 1997 to 2002. See Note 4 of Notes to Alliance's Consolidated Financial
Statements.

Transactions are set forth in the following table, assuming the Transactions
occurred as of September 30, 1997.

            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.
 
  The unaudited pro forma consolidated balance sheet and statements of
operations and accompanying notes should be read in conjunction with the
historical consolidated financial statements of Alliance included elsewhere in
this Prospectus. See "Index to Consolidated Financial Statements."

 * 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

(a) Reflects an annual management fee payable to Apollo Management, L.P. of
    $0.5 million; does not reflect an equal amount of expected general and
    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
    benefits) will be charged to operations upon the closing of the
    Transactions. These amounts have not been reflected in the unaudited pro
    forma consolidated statements of operations.
 
(c) Reflects amortization of deferred financing fees associated with the
    Transactions.
 
(d) Interest expense, as adjusted, reflects the elimination of historical
    interest expense due to the retirement of substantially all of the
    existing debt obligations and assumes that the following indebtedness and
    cash balance was outstanding as of the beginning of the respective
    reporting periods:

  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) 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
    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.
(4) The substantial majority of 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.
(5) Represents period over period revenue growth for customers that generated
    revenues for the entire term of both periods.
(6) 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. 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
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
 
                                      27
<PAGE>
 
approximately 84% of the issued and outstanding common stock of Alliance and
Alliance's existing shareholders will own approximately 10%. See "The
Transactions." 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 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.
 
 
                                      28
<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.
 
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 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.
 
                                      29
<PAGE>
 
  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.
 
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
 
                                      30
<PAGE>
 
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.
 
  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
 
                                      31
<PAGE>
 
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.
 
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 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 at the rate per annum set forth
on the cover page of this Prospectus, 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
 
                                      32
<PAGE>
 
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%. 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
 
                                      36
<PAGE>
 
own MRI systems rather than renewing a contract with a mobile provider. As of
September 30, 1997, the 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 Transactions 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.
 
  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.
 
                                      37
<PAGE>
 
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 for approximately eight years in a high
demand market 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
 
                                      38
<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.
 
                                      39
<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.
 
                                      40
<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
 
                                      41
<PAGE>
 
changes will be delayed until January 1, 1999, with a three year transition
period for implementing the new 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.
 
                                      42
<PAGE>
 
  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 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.
 
 
                                      43
<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
pending against it will have a material adverse effect on its consolidated
financial position or results of operations.

                          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.

  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.
 
                                NEW OPTION PLAN
 
  After the consummation of the Recapitalization, the Company will adopt an
employee option plan pursuant to which options with respect to a total of
454,545 shares of Alliance common stock will be available for grant, and Mr.
Zehner and Mr. Pino will be granted options to purchase 145,000 and 130,000
shares of Alliance common stock, respectively. Fifty percent of the option
shares will vest in equal increments over four years. Fifty percent of the
option shares will vest after seven and one half years (subject to
acceleration if certain per share equity targets are achieved). Vesting of the
options occurs only during an employee's term of employment. The exercise
price for the options is $11.00 per share and the options will expire ten
years from the date of grant.

(1) All options granted in 1996 vest on March 1, 2003; however, vesting of the
    1996 option shares will be accelerated based on achievement of the
    following per share stock prices for 15 consecutive trading days, as
    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.
 
(2) All options were granted at market value (based on the closing price as
    reported on the Nasdaq SmallCap Market on the business day prior to the
    grant date) at the date of grant.
 
(3) Valuations based upon the assumed rates of stock price appreciation are
    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
 
                                      48
<PAGE>
 
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.
 
  Pursuant to the terms of the LTIP, at the effective time of the
Recapitalization, Messrs. Zehner, Pino, White, Andrues and Mericle will be
paid $543,750, $435,000 and $326,250, $217,500 and $217,500, respectively
(before federal and state income taxes) earned by them pursuant to the LTIP
through the date of the Recapitalization.
 
EMPLOYMENT AND RELATED AGREEMENTS
 
  Payments Under Existing Employment Agreements. Each of the Named Executive
Officers has an employment agreement with Alliance. The Recapitalization will
constitute a "change of control" for the purposes of such employment
agreements.
 
  The employment agreements for Messrs. Andrues and Mericle 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 existing 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) 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. Prior to 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.
 
                                      49
<PAGE>
 
  Each 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, 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
Recapitalization pursuant to the existing employment agreements (prior to
federal and state income taxes) will be reduced to approximately $850,000,
$500,000 and $420,000, respectively.
 
  New Employment Agreements for Messrs. Zehner and Pino. Alliance has entered
into employment agreements 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 "New Employment Agreements"). Base compensation under
the New 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 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). In connection with the New
Employment Agreements, Mr. Zehner and Mr. Pino are entitled to receive 145,000
and 130,000 options, respectively, under the New Stock Option Plan.
 
  The term of each New Employment Agreement is initially three years. After
the first year, the New Employment 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.
 
  Agreements Not to Compete. Mr. Zehner and Mr. Pino have also entered into an
agreement not to compete with Alliance. Pursuant to such agreement, Mr. Zehner
and Mr. Pino have each agreed that they will not, prior to the later of five
years following the Recapitalization 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 his
termination 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 of their respective terminations of employment or
the date of ceasing to receive payments under the agreements 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. In consideration of the
non-competition and non-solicitation agreements of Mr. Zehner and Mr. Pino,
Alliance has agreed to make certain payments to Mr. Zehner and Mr. Pino
following the termination of their employment. However, in the event of a
termination with cause or a resignation without good reason (as defined in the
New Employment Agreements), Alliance will be under no obligation to make such
payments.

  Immediately after the Transactions, Apollo will own approximately 84% of the
outstanding shares of common stock of the Company (the "Company Common Stock")
(approximately 74% on a fully diluted basis) and the BT Investor will own
approximately 6% of the outstanding shares of Company Common Stock
(approximately 5% on a fully diluted basis). In addition, immediately
following consummation of the Transactions, through a combination of (i) the
rollover of existing options to purchase shares of Company Common Stock and
(ii) the issuance of options pursuant to the Company's New Option Plan,
management will own in excess of 11% of the shares of Company Common Stock on
a fully diluted basis.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  At the effective time of the Recapitalization, 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 $14.1
million of the Company's Series F Preferred Stock and will receive a financing
fee of $564,000.
 
  Pursuant to an engagement letter, Alliance will pay Salomon Brothers Inc
("Salomon") 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's
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
will be a lender under the Credit Agreement.
 
  Smith Barney Inc. ("Smith Barney") acted as an advisor to an affiliate of
Apollo with respect to the Recapitalization of Alliance, for which Smith
Barney will receive a fee of $1.75 million.
 
  The BT Investor, an affiliate of BT Alex. Brown Incorporated, will invest
approximately $2.7 million in the Company's Common Stock concurrently with the
consummation of the Transactions. Bankers Trust Company, also an affiliate of
BT Alex. Brown Incorporated, will be an agent and lender under the Credit
Agreement. In connection with the Transactions, the BT Investor will purchase
$0.9 million of the Company's Series F Preferred Stock and will receive a
financing fee of $36,000.

                      DESCRIPTION OF THE CREDIT AGREEMENT
 
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.
 
  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 Transactions 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 with respect to the Term Loan Facility 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.
 
                                      53
<PAGE>
 
  (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 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.

                           DESCRIPTION OF THE NOTES
 
  The Notes will be issued under an indenture (the "Indenture"), to be dated
as of      , 1997 by and among Alliance Imaging, Inc., the Guarantors and
    , as Trustee (the "Trustee"). The following summary of certain provisions
of the Indenture does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, the Trust Indenture Act of 1939, as
amended (the "TIA"), and to all of the provisions of the Indenture (a copy of
which has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part), including the definitions of certain terms therein and
those terms made a part of the Indenture by reference to the TIA as in effect
on the date of the Indenture. The definitions of certain capitalized terms
used in the following summary are set forth below under "--Certain
Definitions." For purposes of this section, references to the "Company"
include only Alliance Imaging, Inc. and not its Subsidiaries.
 
  The Notes will be unsecured obligations of the Company, ranking subordinate
in right of payment to all Senior Debt of the Company.
 
  The Notes will be issued in fully registered form only, without coupons, in
denominations of $1,000 and integral multiples thereof. Initially, the Trustee
will act as Paying Agent and Registrar for the Notes. The Notes may be
presented for registration or transfer and exchange at the offices of the
Registrar, which initially will be the Trustee's corporate trust office. The
Company may change any Paying Agent and Registrar without notice to holders of
the Notes (the "Holders"). The Company will pay principal (and premium, if
any) on the Notes at the Trustee's corporate office in New York, New York. At
the Company's option, interest may be paid at the Trustee's corporate trust
office or by check mailed to the registered address of Holders.
 
PRINCIPAL, MATURITY AND INTEREST
 
  The Notes are limited in aggregate principal amount to $265.0 million, of
which $165.0 million will be issued in the Offering, and will mature on      ,
2005. Interest on the Notes will accrue at the rate of   % per annum and will
be payable semiannually in cash on each      and      commencing on      ,
1998, to the persons who are registered Holders at the close of business on
the     and     immediately preceding the applicable interest payment date.
Interest on the Notes will accrue from the most recent date to which interest
has been paid or, if no interest has been paid, from and including the date of
issuance.
 
  The Notes will not be entitled to the benefit of any mandatory sinking fund.
 
REDEMPTION
 
  Optional Redemption. The Notes will be redeemable, at the Company's option,
in whole at any time or in part from time to time, on and after      , 2001,
upon not less than 30 nor more than 60 days' notice, at the following
redemption prices (expressed as percentages of the principal amount thereof)
if redeemed during the twelve-month period commencing on       of the year set
forth below, plus, in each case, accrued and unpaid interest thereon, if any,
to the date of redemption:
 
<TABLE>

      YEAR                                                            PERCENTAGE
      ----                                                            ----------

  Optional Redemption upon Equity Offerings. At any time, or from time to
time, on or prior to       , 2000, the Company may, at its option, use the net
cash proceeds of one or more Equity Offerings (as defined below) to redeem up
to 40% in aggregate principal amount of the Notes at a redemption price equal
to  % of the principal amount thereof plus accrued and unpaid interest
thereon, if any, to the date
 
                                      55
<PAGE>
 
of redemption; provided, however, that after any such redemption the aggregate
principal amount of the Notes outstanding must equal at least 60% of the
aggregate amount of the Notes issued in the Offering plus any additional Notes
issued after the Issue Date pursuant to the Indenture. In order to effect the
foregoing redemption with the net cash proceeds of any Equity Offering, the
Company shall make such redemption not more than 120 days after the
consummation of any such Equity Offering.
 
  As used in the preceding paragraph, "Equity Offering" means a public or
private offering of Qualified Capital Stock (other than public offerings with
respect to the Company's Common Stock on Form S-8) of the Company for
aggregate net cash proceeds to the Company of at least $25.0 million.
 
SELECTION AND NOTICE OF REDEMPTION
 
  In the event that less than all of the Notes are to be redeemed at any time,
selection of such Notes for redemption will be made by the Trustee in
compliance with the requirements of the principal national securities
exchange, if any, on which such Notes are listed or, if such Notes are not
then listed on a national securities exchange, on a pro rata basis, by lot or
by such method as the Trustee shall deem fair and appropriate; provided,
however, that no Notes of a principal amount of $1,000 or less shall be
redeemed in part; provided, further, that if a partial redemption is made with
the net cash proceeds of an Equity Offering, selection of the Notes or
portions thereof for redemption shall be made by the Trustee only on a pro
rata basis or on as nearly a pro rata basis as is practicable (subject to DTC
procedures), unless such method is otherwise prohibited. Notice of redemption
shall be mailed by first-class mail at least 30 but not more than 60 days
before the redemption date to each Holder of Notes to be redeemed at its
registered address. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in a principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof
upon cancellation of the original Note. On and after the redemption date,
interest will cease to accrue on Notes or portions thereof called for
redemption as long as the Company has deposited with the Paying Agent funds in
satisfaction of the applicable redemption price pursuant to the Indenture.
 
SUBORDINATION
 
  The payment of all Obligations on the Notes is subordinated in right of
payment to the prior payment in full in cash or Cash Equivalents of all
Obligations on Senior Debt. Upon any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any liquidation, dissolution, winding up, reorganization,
assignment for the benefit of creditors or marshaling of assets of the Company
or in a bankruptcy, reorganization, insolvency, receivership or other similar
proceeding relating to the Company or its property, whether voluntary or
involuntary, all Obligations due or to become due upon all Senior Debt shall
first be paid in full in cash or Cash Equivalents, or such payment duly
provided for to the satisfaction of the holders of Senior Debt, before any
payment or distribution of any kind or character is made on account of any
Obligations on the Notes, or for the acquisition of any of the Notes for cash
or property or otherwise. If any default occurs and is continuing in the
payment when due, whether at maturity, upon any redemption, by declaration or
otherwise, of any principal of, interest on, unpaid drawings for letters of
credit issued in respect of, or regularly accruing fees with respect to, any
Senior Debt, no payment of any kind or character shall be made by or on behalf
of the Company or any other Person on its or their behalf with respect to any
Obligations on the Notes or to acquire any of the Notes for cash or property
or otherwise.
 
  In addition, if any other event of default occurs and is continuing with
respect to any Designated Senior Debt, as such event of default is defined in
the instrument creating or evidencing such Designated Senior Debt, permitting
the holders of such Designated Senior Debt then outstanding to accelerate the
maturity thereof and if the Representative for the respective issue of
Designated Senior Debt gives written notice of the event of default to the
Trustee (a "Default Notice"), then, unless and until all events of default
have been cured or waived or have ceased to exist or the Trustee receives
notice from the Representative for the respective issue of Designated
 
                                      56
<PAGE>
 
Senior Debt terminating the Blockage Period (as defined below), during the 180
days after the delivery of such Default Notice (the "Blockage Period"),
neither the Company nor any other Person on its behalf shall (x) make any
payment of any kind or character with respect to any Obligations on the Notes
or (y) acquire any of the Notes for cash or property or otherwise.
Notwithstanding anything herein to the contrary, in no event will a Blockage
Period extend beyond 180 days from the date the payment on the Notes was due
and only one such Blockage Period may be commenced within any 360 consecutive
days. No event of default which existed or was continuing on the date of the
commencement of any Blockage Period with respect to the Designated Senior Debt
shall be, or be made, the basis for commencement of a second Blockage Period
by the Representative of such Designated Senior Debt whether or not within a
period of 360 consecutive days, unless such event of default shall have been
cured or waived for a period of not less than 90 consecutive days (it being
acknowledged that any subsequent action, or any breach of any financial
covenants for a period commencing after the date of commencement of such
Blockage Period that, in either case, would give rise to an event of default
pursuant to any provisions under which an event of default previously existed
or was continuing shall constitute a new event of default for this purpose).
 
  By reason of such subordination, in the event of the insolvency of the
Company, creditors of the Company who are not holders of Senior Debt,
including the Holders of the Notes, may recover less, ratably, than holders of
Senior Debt.
 
  After giving effect to the Transactions, on a pro forma basis, at September
30, 1997, the Company would have had approximately $56.9 million of Senior
Debt outstanding.
 
GUARANTEES
 
  Each Guarantor unconditionally guarantees, on a senior subordinated basis,
jointly and severally, to each Holder and the Trustee, the full and prompt
performance of the Company's obligations under the Indenture and the Notes,
including the payment of principal of and interest on the Notes. The
Guarantees will be subordinated to Guarantor Senior Debt on the same basis as
the Notes are subordinated to Senior Debt. The obligations of each Guarantor
are limited to the maximum amount which, after giving effect to all other
contingent and fixed liabilities of such Guarantor and after giving effect to
any collections from or payments made by or on behalf of any other Guarantor
in respect of the obligations of such other Guarantor under its Guarantee or
pursuant to its contribution obligations under the Indenture, will result in
the obligations of such Guarantor under the Guarantee not constituting a
fraudulent conveyance or fraudulent transfer under federal or state law. Each
Guarantor that makes a payment or distribution under a Guarantee shall be
entitled to a contribution from each other Guarantor in an amount pro rata,
based on the net assets of each Guarantor, determined in accordance with GAAP.
 
  Each Guarantor may consolidate with or merge into or sell its assets to the
Company or another Guarantor that is a Wholly Owned Restricted Subsidiary of
the Company without limitation, or with other Persons upon the terms and
conditions set forth in the Indenture. See "Certain Covenants--Merger,
Consolidation and Sale of Assets." In the event all of the Capital Stock of a
Guarantor is sold by the Company and the sale complies with the provisions set
forth in "Certain Covenants--Limitation on Asset Sales," the Guarantor's
Guarantee will be released.
 
  Separate financial statements of the Guarantors are not included herein
because such Guarantors are jointly and severally liable with respect to the
Company's obligations pursuant to the Notes, and the aggregate net assets,
earnings and equity of the Guarantors and the Company are substantially
equivalent to the net assets, earnings and equity of the Company on a
consolidated basis. Accordingly, management has determined that separate
financial statements of each Guarantor would not provide any material
information to prospective purchasers of the Notes.
 
CHANGE OF CONTROL
 
  The Indenture will provide that upon the occurrence of a Change of Control,
each Holder will have the right to require that the Company purchase all or a
portion of such Holder's Notes pursuant to the offer described
 
                                      57
<PAGE>
 
below (the "Change of Control Offer"), at a purchase price equal to 101% of
the principal amount thereof plus accrued interest to the date of purchase.
 
  The Indenture will provide that, prior to the mailing of the notice referred
to below, but in any event within 30 days following any Change of Control, the
Company covenants to (i) repay in full and terminate all commitments under
Indebtedness under the Credit Agreement and all other Senior Debt the terms of
which require repayment upon a Change of Control or offer to repay in full and
terminate all commitments under all Indebtedness under the Credit Agreement
and all other such Senior Debt and to repay the Indebtedness owed to each
lender which has accepted such offer or (ii) obtain the requisite consents
under the Credit Agreement and all other Senior Debt to permit the repurchase
of the Notes as provided below. The Company shall first comply with the
covenant in the immediately preceding sentence before it shall be required to
repurchase Notes pursuant to the provisions described below. The Company's
failure to comply with the covenant described in the immediately preceding
sentence shall constitute an Event of Default described in clause (iii) and
not in clause (ii) under "Events of Default" below.
 
  Within 30 days following the date upon which the Change of Control occurred,
the Company must send, by first class mail, a notice to each Holder, with a
copy to the Trustee, which notice shall govern the terms of the Change of
Control Offer. Such notice shall state, among other things, the purchase date,
which must be no earlier than 30 days nor later than 45 days from the date
such notice is mailed, other than as may be required by law (the "Change of
Control Payment Date"). Holders electing to have a Note purchased pursuant to
a Change of Control Offer will be required to surrender the Note, with the
form entitled "Option of Holder to Elect Purchase" on the reverse of the Note
completed, to the Paying Agent at the address specified in the notice prior to
the close of business on the third business day prior to the Change of Control
Payment Date.
 
  If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
purchase price for all the Notes that might be delivered by Holders seeking to
accept the Change of Control Offer. In the event the Company is required to
purchase outstanding Notes pursuant to a Change of Control Offer, the Company
expects that it would seek third party financing to the extent it does not
have available funds to meet its purchase obligations. However, there can be
no assurance that the Company would be able to obtain such financing.
 
  Neither the Board of Directors of the Company nor the Trustee may waive the
covenant relating to a Holder's right to redemption upon a Change of Control.
Restrictions in the Indenture described herein on the ability of the Company
and its Restricted Subsidiaries to incur additional Indebtedness, to grant
liens on its property, to make Restricted Payments and to make Asset Sales may
also make more difficult or discourage a takeover of the Company, whether
favored or opposed by the management of the Company. Consummation of any such
transaction in certain circumstances may require redemption or repurchase of
the Notes, and there can be no assurance that the Company or the acquiring
party will have sufficient financial resources to effect such redemption or
repurchase. Such restrictions and the restrictions on transactions with
Affiliates may, in certain circumstances, make more difficult or discourage
any leveraged buyout of the Company or any of its Restricted Subsidiaries by
the management of the Company. While such restrictions cover a wide variety of
arrangements which have traditionally been used to effect highly leveraged
transactions, the Indenture may not afford the Holders of Notes protection in
all circumstances from the adverse aspects of a highly leveraged transaction,
reorganization, restructuring, merger or similar transaction.
 
  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Change of Control Offer. To the extent that
the provisions of any securities laws or regulations conflict with the "Change
of Control" provisions of the Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the "Change of Control" provisions of the
Indenture by virtue thereof.
 
  The definition of "Change of Control" includes, among other transactions, a
disposition of all or substantially all of the property and assets of the
Company. With respect to the disposition of property or assets,
 
                                      58
<PAGE>
 
the phrase "all or substantially all" as used in the Indenture varies
according to the facts and circumstances of the subject transaction, has no
clearly established meaning under New York law (which is the choice of law
under the Indenture) and is subject to judicial interpretation. Accordingly,
in certain circumstances, there may be a degree of uncertainty in ascertaining
whether a particular transaction would involve a disposition of "all or
substantially all" of the property or assets of a Person, and therefore it may
be unclear whether a Change of Control has occurred and whether the Company is
required to make an offer to repurchase the Notes as described above.
 
CERTAIN COVENANTS
 
  The Indenture will contain, among others, the following covenants:
 
  Limitation on Incurrence of Additional Indebtedness. The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume, guarantee, acquire, become liable,
contingently or otherwise, with respect to, or otherwise become responsible
for payment of (collectively, "incur") any Indebtedness (other than Permitted
Indebtedness); provided, however, that if no Default or Event of Default shall
have occurred and be continuing at the time of or as a consequence of the
incurrence of any such Indebtedness, the Company or any of the Guarantors may
incur Indebtedness (including, without limitation, Acquired Indebtedness) and
Restricted Subsidiaries of the Company may incur Acquired Indebtedness, in
each case if on the date of the incurrence of such Indebtedness, after giving
effect to the incurrence thereof, the Consolidated Fixed Charge Coverage Ratio
of the Company is greater than 1.75 to 1.0 if such incurrence is on or prior
to December 31, 1999 and 2.0 to 1.0 if such incurrence is thereafter.
 
  Limitation on Restricted Payments. The Company will not, and will not cause
or permit any of its Restricted Subsidiaries to, directly or indirectly, (a)
declare or pay any dividend or make any distribution (other than dividends or
distributions payable in Qualified Capital Stock of the Company) on or in
respect of shares of the Company's Capital Stock to holders of such Capital
Stock, (b) purchase, redeem or otherwise acquire or retire for value any
Capital Stock of the Company or any warrants, rights or options to purchase or
acquire shares of any class of such Capital Stock, (c) make any principal
payment on, purchase, defease, redeem, prepay, decrease or otherwise acquire
or retire for value, prior to any scheduled final maturity, scheduled
repayment or scheduled sinking fund payment, any Indebtedness of the Company
that is subordinate or junior in right of payment to the Notes or (d) make any
Investment (other than Permitted Investments) (each of the foregoing actions
set forth in clauses (a), (b), (c) and (d) being referred to as a "Restricted
Payment"), if at the time of such Restricted Payment or immediately after
giving effect thereto, (i) a Default or an Event of Default shall have
occurred and be continuing or (ii) the Company is not able to incur at least
$1.00 of additional Indebtedness (other than Permitted Indebtedness) in
compliance with the "Limitation on Incurrence of Additional Indebtedness"
covenant or (iii) the aggregate amount of Restricted Payments (including such
proposed Restricted Payment) made subsequent to the Issue Date (the amount
expended for such purposes, if other than in cash, being the fair market value
of such property as determined reasonably and in good faith by the Board of
Directors of the Company) shall exceed the sum of: (w) 50% of the cumulative
Consolidated Net Income (or if cumulative Consolidated Net Income shall be a
loss, minus 100% of such loss) of the Company earned subsequent to the Issue
Date and on or prior to the date the Restricted Payment occurs (the "Reference
Date") (treating such period as a single accounting period); plus (x) 100% of
the aggregate net cash proceeds received by the Company from any Person (other
than a Subsidiary of the Company) from the issuance and sale subsequent to the
Issue Date and on or prior to the Reference Date of Qualified Capital Stock of
the Company; plus (y) without duplication of any amounts included in clause
(iii)(x) above, 100% of the aggregate net cash proceeds of any equity
contribution received by the Company from a holder of the Company's Capital
Stock; plus (z) without duplication, the sum of (1) the aggregate amount
returned in cash on or with respect to Investments (other than Permitted
Investments) made subsequent to the Issue Date whether through interest
payments, principal payments, dividends or other distributions or payments,
(2) the net cash proceeds received by the Company or any Restricted Subsidiary
of the Company from the disposition of all or any portion of such Investments
(other than to a Subsidiary of the Company) and (3) upon redesignation of an
Unrestricted Subsidiary as a Restricted Subsidiary, the fair market value of
such Subsidiary; provided, however, that the sum
 
                                      59
<PAGE>
 
of clauses (1), (2) and (3) above shall not exceed the aggregate amount of all
such Investments made subsequent to the Issue Date.
 
  Notwithstanding the foregoing, the provisions set forth in the immediately
preceding paragraph do not prohibit: (1) the payment of any dividend within 60
days after the date of declaration of such dividend if the dividend would have
been permitted on the date of declaration; (2) if no Default or Event of
Default shall have occurred and be continuing, the acquisition of any shares
of Capital Stock of the Company, either (i) solely in exchange for shares of
Qualified Capital Stock of the Company or (ii) through the application of net
proceeds of a substantially concurrent sale for cash (other than to a
Subsidiary of the Company) of shares of Qualified Capital Stock of the
Company; (3) if no Default or Event of Default shall have occurred and be
continuing, the acquisition of any Indebtedness of the Company that is
subordinate or junior in right of payment to the Notes either (i) solely in
exchange for shares of Qualified Capital Stock of the Company, or (ii) through
the application of net proceeds of a substantially concurrent sale for cash
(other than to a Subsidiary of the Company) of (A) shares of Qualified Capital
Stock of the Company or (B) Refinancing Indebtedness; (4) so long as no
Default or Event of Default shall have occurred and be continuing, repurchases
by the Company of Common Stock of the Company from employees of the Company or
any of its Subsidiaries or their authorized representatives upon the death,
disability or termination of employment of such employees, in an amount not to
exceed $5.0 million in any calendar year or $15.0 million in the aggregate;
(5) so long as no Default or Event of Default shall have occurred or be
continuing, the declaration and payment of dividends to holders of any class
or series of Preferred Stock (other than Disqualified Capital Stock) issued
after the Issue Date, provided that after giving effect to such issuance on a
pro forma basis, the Company would have had a Consolidated Fixed Charge
Coverage Ratio of at least 1.75 to 1.00; (6) the payment of dividends on the
Company's Common Stock, following the first public offering of the Company's
Common Stock after the Issue Date, of up to 6% per annum of the net proceeds
received by the Company in such public offering, other than public offerings
with respect to the Company's Common Stock registered on Form S-8; (7) the
repurchase, retirement or other acquisition or retirement for value of equity
interests of the Company in existence on the Issue Date and from the persons
holding such equity interests on the Issue Date and which are not held by
Apollo or any of its Affiliates or members of management of the Company and
its Subsidiaries on the Issue Date (including any equity interests issued in
respect of such equity interests as a result of a stock split,
recapitalization, merger, combination, consolidation or similar transaction),
provided, however, that the Company shall be permitted to make Restricted
Payments under this clause only if after giving effect thereto, the Company
would be permitted to incur at least $1.00 of additional Indebtedness (other
than Permitted Indebtedness) pursuant to the "Limitation on Incurrence of
Additional Indebtedness" covenant; (8) so long as no Default or Event of
Default shall have occurred and be continuing, the repurchase, retirement or
other acquisition or retirement for value of the Company's Series F Preferred
Stock, provided that after giving effect to such repurchase, retirement or
other acquisition or retirement for value on a pro forma basis, the Company
would have had a Consolidated Fixed Charge Coverage Ratio of at least 2.5 to
1.0; and (9) other Restricted Payments in an aggregate amount not to exceed
$5.0 million. In determining the aggregate amount of Restricted Payments made
subsequent to the Issue Date in accordance with clause (iii) of the
immediately preceding paragraph, amounts expended pursuant to clauses (1),
(2), (4), (5), (6), (7), (8) and (9) shall be included in such calculation.
 
  Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustee an officers' certificate stating that such Restricted
Payment complies with the Indenture and setting forth in reasonable detail the
basis upon which the required calculations were computed, which calculations
may be based upon the Company's latest available internal quarterly financial
statements.
 
  Limitation on Asset Sales. The Company will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless (i) the
Company or the applicable Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market
value of the assets sold or otherwise disposed of (as determined in good faith
by the Company's Board of Directors), (ii) at least 75% of the consideration
received by the Company or the Restricted Subsidiary, as the case may be, from
such Asset Sale shall be in the form of cash or Cash Equivalents and is
received at the time of such disposition; provided that the amount of (a) any
liabilities (as shown on the Company's or such Restricted Subsidiary's most
recent balance sheet) of the Company or any Restricted Subsidiary (other than
liabilities that are by their terms
 
                                      60
<PAGE>
 
subordinated to the Notes) that are assumed by the transferee of any such
assets, and (b) any notes or other obligations received by the Company or any
such Restricted Subsidiary from such transferee that are converted by the
Company or such Restricted Subsidiary into cash within 180 days after such
Asset Sale (to the extent of the cash received) shall be deemed to be cash for
the purposes of this provision; and (iii) upon the consummation of an Asset
Sale, the Company shall apply, or cause such Restricted Subsidiary to apply,
the Net Cash Proceeds relating to such Asset Sale within 360 days of receipt
thereof either (A) to prepay any Senior Debt or Guarantor Senior Debt and, in
the case of any Senior Debt or Guarantor Senior Debt under any revolving
credit facility, effect a permanent reduction in the availability under such
revolving credit facility, (B) to make an Investment in properties and assets
that replace the properties and assets that were the subject of such Asset
Sale or in properties and assets that will be used in the business of the
Company and its Restricted Subsidiaries as existing on the Issue Date or in
businesses the same, similar or reasonably related thereto ("Replacement
Assets"), or (C) a combination of prepayment and investment permitted by the
foregoing clauses (iii)(A) and (iii)(B). On the 361st day after an Asset Sale
or such earlier date, if any, as the Board of Directors of the Company or of
such Restricted Subsidiary determines not to apply the Net Cash Proceeds
relating to such Asset Sale as set forth in clauses (iii)(A), (iii)(B) and
(iii)(C) of the next preceding sentence (each, a "Net Proceeds Offer Trigger
Date"), such aggregate amount of Net Cash Proceeds which have not been applied
on or before such Net Proceeds Offer Trigger Date as permitted in clauses
(iii)(A), (iii)(B) and (iii)(C) of the next preceding sentence (each a "Net
Proceeds Offer Amount") shall be applied by the Company or such Restricted
Subsidiary to make an offer to purchase (the "Net Proceeds Offer") on a date
(the "Net Proceeds Offer Payment Date") not less than 30 nor more than 45 days
following the applicable Net Proceeds Offer Trigger Date, from all Holders on
a pro rata basis, that amount of Notes equal to the Net Proceeds Offer Amount
at a price equal to 100% of the principal amount of the Notes to be purchased,
plus accrued and unpaid interest thereon, if any, to the date of purchase;
provided, however, that if at any time any non-cash consideration received by
the Company or any Restricted Subsidiary of the Company, as the case may be,
in connection with any Asset Sale is converted into or sold or otherwise
disposed of for cash (other than interest received with respect to any such
non-cash consideration), then such conversion or disposition shall be deemed
to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall
be applied in accordance with this covenant. The Company may defer the Net
Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer
Amount equal to or in excess of $5.0 million resulting from one or more Asset
Sales (at which time, the entire unutilized Net Proceeds Offer Amount, and not
just the amount in excess of $5.0 million, shall be applied as required
pursuant to this paragraph).
 
  In the event of the transfer of substantially all (but not all) of the
property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under "--Merger, Consolidation
and Sale of Assets," the successor corporation shall be deemed to have sold
the properties and assets of the Company and its Restricted Subsidiaries not
so transferred for purposes of this covenant, and shall comply with the
provisions of this covenant with respect to such deemed sale as if it were an
Asset Sale. In addition, the fair market value of such properties and assets
of the Company or its Restricted Subsidiaries deemed to be sold shall be
deemed to be Net Cash Proceeds for purposes of this covenant.
 
  Each Net Proceeds Offer will be mailed to the record Holders as shown on the
register of Holders within 25 days following the Net Proceeds Offer Trigger
Date, with a copy to the Trustee, and shall comply with the procedures set
forth in the Indenture. Upon receiving notice of the Net Proceeds Offer,
Holders may elect to tender their Notes in whole or in part in integral
multiples of $1,000 in exchange for cash. To the extent Holders properly
tender Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of
tendering Holders will be purchased on a pro rata basis (based on amounts
tendered). A Net Proceeds Offer shall remain open for a period of 20 business
days or such longer period as may be required by law.
 
  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the
provisions of any securities laws or regulations conflict with the "Asset
Sale" provisions of the Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the "Asset Sale" provisions of the Indenture by
virtue thereof.

  Limitation on Dividend and Other Payment Restrictions Affecting
Subsidiaries. The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause
or permit to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary of the Company to (a) pay dividends or
make any other distributions on or in respect of its Capital Stock; (b) make
loans or advances or to pay any Indebtedness or other obligation owed to the
Company or any other Restricted Subsidiary of the Company; or (c) transfer any
of its property or assets to the Company or any other Restricted Subsidiary of
the Company, except for such encumbrances or restrictions existing under or by
reason of: (1) applicable law; (2) the Indenture; (3) the Credit Agreement;
(4) customary non-assignment provisions of any contract or any lease governing
a leasehold interest of any Restricted Subsidiary of the Company; (5) any
instrument governing Acquired Indebtedness, which encumbrance or restriction
is not applicable to any Person, or the properties or assets of any Person,
other than the Person or the properties or assets of the Person so acquired;
(6) agreements existing on the Issue Date to the extent and in the manner such
agreements are in effect on the Issue Date; (7) purchase money obligations for
property acquired in the ordinary course of business that impose restrictions
of the nature discussed in clause (c) above on the property so acquired; (8)
contracts for the sale of assets, including, without limitation, customary
restrictions with respect to a Restricted Subsidiary of the Company pursuant
to an agreement that has been entered into for the sale or disposition of all
or substantially all of the Capital Stock or assets of such Restricted
Subsidiary; (9) secured Indebtedness otherwise permitted to be incurred
pursuant to the covenants described under "Limitation on Incurrence of
Additional Indebtedness" and "Limitation on Liens" that limit the right of the
debtor to dispose of the assets securing such Indebtedness; (10) customary
provisions in joint venture agreements and other similar agreements entered
into in the ordinary course of business; (11) an agreement governing
Indebtedness incurred to Refinance the Indebtedness issued, assumed or
incurred pursuant to an agreement referred to in clauses (1) through (10)
above; provided, however, that the provisions relating to such encumbrance or
restriction contained in any such Indebtedness are no less favorable to the
Company in any material respect as determined by the Board of Directors of the
Company in their reasonable and good faith judgment than the provisions
relating to such encumbrance or restriction contained in agreements referred
to in such clauses; or (12) an agreement governing Indebtedness permitted to
be incurred pursuant to the "Limitation on Incurrence on Additional
Indebtedness" covenant; provided that the provisions relating to such
encumbrance or restriction contained in such Indebtedness are no less
favorable to the Company in any material respect as determined by the Board of
Directors of the Company in their reasonable and good faith judgment than the
provisions contained in the Credit Agreement as in effect on the Issue Date.
 
  Limitation on Liens. The Company will not, and will not cause or permit any
of its Restricted Subsidiaries to, directly or indirectly, create, incur,
assume or permit or suffer to exist any Liens of any kind against or upon any
property or assets of the Company or any of its Restricted Subsidiaries
whether owned on the Issue Date or acquired after the Issue Date, or any
proceeds therefrom, or assign or otherwise convey any right to receive income
or profits therefrom unless (i) in the case of Liens securing Indebtedness
that is expressly subordinate or junior in right of payment to the Notes, the
Notes are secured by a Lien on such property, assets or proceeds that is
senior in priority to such Liens and (ii) in all other cases, the Notes are
equally and ratably secured, except for (A) Liens existing as of the Issue
Date to the extent and in the manner such Liens are in effect on the Issue
Date; (B) Liens securing Senior Debt and Liens securing Guarantor Senior Debt;
(C) Liens securing the Notes and the Guarantees; (D) Liens of the Company or a
Wholly Owned Restricted Subsidiary of the Company on assets of any Restricted
Subsidiary of the Company; (E) Liens securing Refinancing Indebtedness which
is incurred to Refinance any Indebtedness which has been secured by a Lien
permitted under the Indenture and which has been incurred in accordance with
the provisions of the Indenture; provided, however, that such Liens (A) are no
less favorable to the Holders and are not more favorable to the lienholders
with respect to such Liens than the Liens in respect of the Indebtedness being
Refinanced and (B) do not extend to or cover any property or assets of the
Company or any of its Restricted Subsidiaries not securing the Indebtedness so
Refinanced; and (F) Permitted Liens.
 
  Prohibition on Incurrence of Senior Subordinated Debt. The Company and the
Guarantors will not incur or suffer to exist Indebtedness that is senior in
right of payment to the Notes or the Guarantees, as the case may be, and
subordinate in right of payment by its terms to any other Indebtedness of the
Company or such Guarantor, as the case may be.
 
                                      62

  Merger, Consolidation and Sale of Assets. The Company will not, in a single
transaction or series of related transactions, consolidate or merge with or
into any Person, or sell, assign, transfer, lease, convey or otherwise dispose
of (or cause or permit any Restricted Subsidiary of the Company to sell,
assign, transfer, lease, convey or otherwise dispose of) all or substantially
all of the Company's assets (determined on a consolidated basis for the
Company and the Company's Restricted Subsidiaries) whether as an entirety or
substantially as an entirety to any Person unless (i) either (1) the Company
shall be the surviving or continuing corporation or (2) the Person (if other
than the Company) formed by such consolidation or into which the Company is
merged or the Person which acquires by sale, assignment, transfer, lease,
conveyance or other disposition the properties and assets of the Company and
of the Company's Restricted Subsidiaries substantially as an entirety (the
"Surviving Entity") (x) shall be a corporation organized and validly existing
under the laws of the United States or any State thereof or the District of
Columbia and (y) shall expressly assume, by supplemental indenture (in form
and substance satisfactory to the Trustee), executed and delivered to the
Trustee, the due and punctual payment of the principal of, and premium, if
any, and interest on all of the Notes and the performance of every covenant of
the Notes and the Indenture on the part of the Company to be performed or
observed; (ii) immediately after giving effect to such transaction on a pro
forma basis and the assumption contemplated by clause (i)(2)(y) above
(including giving effect to any Indebtedness and Acquired Indebtedness
incurred or anticipated to be incurred in connection with or in respect of
such transaction), the Company or such Surviving Entity, as the case may be,
shall be able to incur at least $1.00 of additional Indebtedness (other than
Permitted Indebtedness) pursuant to the "Limitation on Incurrence of
Additional Indebtedness" covenant; (iii) immediately before and immediately
after giving effect to such transaction and the assumption contemplated by
clause (i)(2)(y) above (including, without limitation, giving effect to any
Indebtedness and Acquired Indebtedness incurred or anticipated to be incurred
and any Lien granted in connection with or in respect of the transaction), no
Default or Event of Default shall have occurred or be continuing; and (iv) the
Company or the Surviving Entity, as the case may be, shall have delivered to
the Trustee an officers' certificate and an opinion of counsel, each stating
that such consolidation, merger, sale, assignment, transfer, lease, conveyance
or other disposition and, if a supplemental indenture is required in
connection with such transaction, such supplemental indenture comply with the
applicable provisions of the Indenture and that all conditions precedent in
the Indenture relating to such transaction have been satisfied.
 
  Notwithstanding the foregoing, the merger of the Company with an Affiliate
incorporated solely for the purpose of reincorporating the Company in another
jurisdiction shall be permitted.
 
  For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties or assets of one or more Restricted
Subsidiaries of the Company the Capital Stock of which constitutes all or
substantially all of the properties and assets of the Company, shall be deemed
to be the transfer of all or substantially all of the properties and assets of
the Company.
 
  The Indenture will provide that upon any consolidation, combination or
merger or any transfer of all or substantially all of the assets of the
Company in accordance with the foregoing, in which the Company is not the
continuing corporation, the successor Person formed by such consolidation or
into which the Company is merged or to which such conveyance, lease or
transfer is made shall succeed to, and be substituted for, and may exercise
every right and power of, the Company under the Indenture and the Notes with
the same effect as if such Surviving Entity had been named as such.
 
  Each Guarantor (other than any Guarantor whose Guarantee is to be released
in accordance with the terms of the Guarantee and the Indenture in connection
with any transaction complying with the provisions of "--Limitation on Asset
Sales") will not, and the Company will not cause or permit any Guarantor to,
consolidate with or merge with or into any Person other than the Company or
any other Guarantor unless (i) the entity formed by or surviving any such
consolidation or merger (if other than the Guarantor) or to which such sale,
lease, conveyance or other disposition shall have been made is a corporation
organized and existing under the laws of the United States or any State
thereof or the District of Columbia; (ii) such entity assumes by supplemental
indenture all of the obligations of the Guarantor on the Guarantee; (iii)
immediately after giving
 
                                      63
<PAGE>
 
effect to such transaction, no Default or Event of Default shall have occurred
and be continuing; and (iv) immediately after giving effect to such
transaction and the use of any net proceeds therefrom on a pro forma basis,
the Company could satisfy the provisions of clause (ii) of the first paragraph
of this covenant. Any merger or consolidation of a Guarantor with and into the
Company (with the Company being the surviving entity) or another Guarantor
that is a Wholly Owned Restricted Subsidiary of the Company need only comply
with clause (iv) of the first paragraph of this covenant.
 
  Limitations on Transactions with Affiliates. (a) The Company will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly,
enter into or permit to exist any transaction or series of related
transactions (including, without limitation, the purchase, sale, lease or
exchange of any property or the rendering of any service) with, or for the
benefit of, any of its Affiliates (each an "Affiliate Transaction"), other
than (x) Affiliate Transactions permitted under paragraph (b) below and (y)
Affiliate Transactions on terms that are no less favorable than those that
might reasonably have been obtained in a comparable transaction at such time
on an arm's-length basis from a Person that is not an Affiliate of the Company
or such Restricted Subsidiary. All Affiliate Transactions (and each series of
related Affiliate Transactions which are similar or part of a common plan)
involving aggregate payments or other property with a fair market value in
excess of $1.0 million shall be approved by the Board of Directors of the
Company or such Restricted Subsidiary, as the case may be, such approval to be
evidenced by a Board Resolution stating that such Board of Directors has
determined that such transaction complies with the foregoing provisions. If
the Company or any Restricted Subsidiary of the Company enters into an
Affiliate Transaction (or a series of related Affiliate Transactions related
to a common plan) that involves an aggregate fair market value of more than
$10.0 million, the Company or such Restricted Subsidiary, as the case may be,
shall, prior to the consummation thereof, obtain a favorable opinion as to the
fairness of such transaction or series of related transactions to the Company
or the relevant Restricted Subsidiary, as the case may be, from a financial
point of view, from an Independent Financial Advisor and file the same with
the Trustee.
 
  (b) The restrictions set forth in clause (a) shall not apply to (i)
reasonable fees and compensation paid to and indemnity provided on behalf of,
officers, directors, employees or consultants of the Company or any Restricted
Subsidiary of the Company as determined in good faith by the Company's Board
of Directors; (ii) transactions exclusively between or among the Company and
any of its Wholly Owned Restricted Subsidiaries or exclusively between or
among such Wholly Owned Restricted Subsidiaries, provided such transactions
are not otherwise prohibited by the Indenture; (iii) any agreement as in
effect as of the Issue Date or any amendment thereto or any transaction
contemplated thereby (including pursuant to any amendment thereto) in any
replacement agreement thereto so long as any such amendment or replacement
agreement is not more disadvantageous to the Holders in any material respect
than the original agreement as in effect on the Issue Date; (iv) Restricted
Payments permitted by the Indenture; (v) transactions in which the Company or
any of its Restricted Subsidiaries, as the case may be, delivers to the
Trustee a letter from an Independent Financial Advisor stating that such
transaction is fair to the Company or such Restricted Subsidiary from a
financial point of view or meets the requirements of the first sentence of
paragraph (a) above; (vi) the existence of, or the performance by the Company
or any of its Restricted Subsidiaries of its obligations under the terms of,
any stockholders agreement (including any registration rights agreement or
purchase agreement related thereto) to which it is a party as of the Issue
Date and any similar agreements which it may enter into thereafter; provided,
however, that the existence of, or the performance by the Company or any of
its Restricted Subsidiaries of obligations under, any future amendment to any
such existing agreement or under any similar agreement entered into after that
Issue Date shall only be permitted by this clause to the extent that the terms
of any such, amendment or new agreement are not otherwise disadvantageous to
the holders of the Notes in any material respect; (vii) loans to employees of
the Company and its Subsidiaries which are approved by the Board of Directors
of the Company in good faith; (viii) the payment of all fees and expenses
related to the Transactions; and (ix) transactions with customers, clients,
suppliers, or purchasers or sellers of goods or services, in each case in the
ordinary course of business and otherwise in compliance with the terms of the
Indenture, which are fair to the Company or its Restricted Subsidiaries, in
the reasonable determination of the Board of Directors of the Company or the
senior management thereof, or are on terms at least as favorable as might
reasonably have been obtained at such time from an unaffiliated party.
 
                                      64

  Additional Subsidiary Guarantees. If the Company or any of its Restricted
Subsidiaries transfers or causes to be transferred, in one transaction or a
series of related transactions, any property to any domestic Restricted
Subsidiary that is not a Guarantor, or if the Company or any of its Restricted
Subsidiaries shall organize, acquire or otherwise invest in another domestic
Restricted Subsidiary having total equity value in excess of $1.0 million,
then such transferee or acquired or other Restricted Subsidiary shall (i)
execute and deliver to the Trustee a supplemental indenture in form reasonably
satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall
unconditionally guarantee all of the Company's obligations under the Notes and
the Indenture on the terms set forth in the Indenture and (ii) deliver to the
Trustee an opinion of counsel that such supplemental indenture has been duly
authorized, executed and delivered by such Restricted Subsidiary and
constitutes a legal, valid, binding and enforceable obligation of such
Restricted Subsidiary. Thereafter, such Restricted Subsidiary shall be a
Guarantor for all purposes of the Indenture.
 
  Reports to Holders. The Indenture will provide that the Company will deliver
to the Trustee within 15 days after the filing of the same with the
Commission, copies of the quarterly and annual reports and of the information,
documents and other reports, if any, which the Company is required to file
with the Commission pursuant to Section 13 or 15(d) of the Exchange Act. The
Indenture further provides that, notwithstanding that the Company may not be
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company will file with the Commission, to the extent permitted, and
provide the Trustee and Holders with such annual reports and such information,
documents and other reports specified in Sections 13 and 15(d) of the Exchange
Act. The Company will also comply with the other provisions of TIA (S) 314(a).
 
EVENTS OF DEFAULT
 
  The following events are defined in the Indenture as "Events of Default":
 
    (i) the failure to pay interest on any Notes when the same becomes due
  and payable and the default continues for a period of 30 days (whether or
  not such payment shall be prohibited by the subordination provisions of the
  Indenture);
 
    (ii) the failure to pay the principal on any Notes, when such principal
  becomes due and payable, at maturity, upon redemption or otherwise
  (including the failure to make a payment to purchase Notes tendered
  pursuant to a Change of Control Offer or a Net Proceeds Offer) (whether or
  not such payment shall be prohibited by the subordination provisions of the
  Indenture);
 
    (iii) a default in the observance or performance of any other covenant or
  agreement contained in the Indenture which default continues for a period
  of 30 days after the Company receives written notice specifying the default
  (and demanding that such default be remedied) from the Trustee or the
  Holders of at least 25% of the outstanding principal amount of the Notes;
 
    (iv) the failure to pay at final stated maturity (giving effect to any
  applicable grace periods and any extensions thereof) the principal amount
  of any Indebtedness of the Company or any Restricted Subsidiary of the
  Company, or the acceleration of the final stated maturity of any such
  Indebtedness if the aggregate principal amount of such Indebtedness,
  together with the principal amount of any other such Indebtedness in
  default for failure to pay principal at final stated maturity or which has
  been accelerated, aggregates $5.0 million or more at any time;
 
    (v) one or more judgments in an aggregate amount in excess of $5.0
  million shall have been rendered against the Company or any of its
  Restricted Subsidiaries and such judgments remain undischarged, unpaid or
  unstayed for a period of 60 days after such judgment or judgments become
  final and non-appealable;
 
    (vi) certain events of bankruptcy affecting the Company or any of its
  Significant Subsidiaries; or
 
    (vii) any of the Guarantees ceases to be in full force and effect or any
  of the Guarantees is declared to be null and void and unenforceable or any
  of the Guarantees is found to be invalid or any of the Guarantors denies
  its liability under its Guarantee (other than by reason of release of a
  Guarantor in accordance with the terms of the Indenture).
 
                                      65
<PAGE>
 
  If an Event of Default (other than an Event of Default specified in clause
(vi) above with respect to the Company) shall occur and be continuing, the
Trustee or the Holders of at least 25% in principal amount of outstanding
Notes may declare the principal of and accrued interest on all the Notes to be
due and payable by notice in writing to the Company and the Trustee specifying
the respective Event of Default and that it is a "notice of acceleration" (the
"Acceleration Notice"), and the same (i) shall become immediately due and
payable or (ii) if there are any amounts outstanding under the Credit
Agreement, shall become immediately due and payable upon the first to occur of
an acceleration under the Credit Agreement or 5 business days after receipt by
the Company and the Representative under the Credit Agreement of such
Acceleration Notice. If an Event of Default specified in clause (vi) above
with respect to the Company occurs and is continuing, then all unpaid
principal of, and premium, if any, and accrued and unpaid interest on all of
the outstanding Notes shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.
 
  The Indenture will provide that, at any time after a declaration of
acceleration with respect to the Notes as described in the preceding
paragraph, the Holders of a majority in principal amount of the Notes may
rescind and cancel such declaration and its consequences (i) if the rescission
would not conflict with any judgment or decree, (ii) if all existing Events of
Default have been cured or waived except nonpayment of principal or interest
that has become due solely because of the acceleration, (iii) to the extent
the payment of such interest is lawful, interest on overdue installments of
interest and overdue principal, which has become due otherwise than by such
declaration of acceleration, has been paid, (iv) if the Company has paid the
Trustee its reasonable compensation and reimbursed the Trustee for its
expenses, disbursements and advances and (v) in the event of the cure or
waiver of an Event of Default of the type described in clause (vi) of the
description above of Events of Default, the Trustee shall have received an
officers' certificate and an opinion of counsel that such Event of Default has
been cured or waived. No such rescission shall affect any subsequent Default
or impair any right consequent thereto.
 
  The Holders of a majority in principal amount of the Notes may waive any
existing Default or Event of Default under the Indenture, and its
consequences, except a default in the payment of the principal of or interest
on any Notes.
 
  Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture and under the TIA. Subject to the provisions of the
Indenture relating to the duties of the Trustee, the Trustee is under no
obligation to exercise any of its rights or powers under the Indenture at the
request, order or direction of any of the Holders, unless such Holders have
offered to the Trustee reasonable indemnity. Subject to all provisions of the
Indenture and applicable law, the Holders of a majority in aggregate principal
amount of the then outstanding Notes have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.
 
  Under the Indenture, the Company is required to provide an officers'
certificate to the Trustee promptly upon any such officer obtaining knowledge
of any Default or Event of Default (provided that such officers shall provide
such certification at least annually whether or not they know of any Default
or Event of Default) that has occurred and, if applicable, describe such
Default or Event of Default and the status thereof.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS
 
  No director, officer, employee or stockholder of the Company, as such, shall
have any liability for any obligations of the Company under the Notes or the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives
and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
  The Company may, at its option and at any time, elect to have its
obligations and the obligations of the Guarantors discharged with respect to
the outstanding Notes ("Legal Defeasance"). Such Legal Defeasance
 
                                      66
<PAGE>
 
means that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by the outstanding Notes, except for (i) the rights
of Holders to receive payments in respect of the principal of, premium, if
any, and interest on the Notes when such payments are due, (ii) the Company's
obligations with respect to the Notes concerning issuing temporary Notes,
registration of Notes, mutilated, destroyed, lost or stolen Notes and the
maintenance of an office or agency for payments, (iii) the rights, powers,
trust, duties and immunities of the Trustee and the Company's obligations in
connection therewith and (iv) the Legal Defeasance provisions of the
Indenture. In addition, the Company may, at its option and at any time, elect
to have the obligations of the Company released with respect to certain
covenants that are described in the Indenture ("Covenant Defeasance") and
thereafter any omission to comply with such obligations shall not constitute a
Default or Event of Default with respect to the Notes. In the event Covenant
Defeasance occurs, certain events (not including non-payment, bankruptcy,
receivership, reorganization and insolvency events) described under "Events of
Default" will no longer constitute an Event of Default with respect to the
Notes.
 
  In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders cash in U.S. dollars, non-callable U.S. government obligations,
or a combination thereof, in such amounts as will be sufficient, in the
opinion of a nationally recognized firm of independent public accountants, to
pay the principal of, premium, if any, and interest on the Notes on the stated
date for payment thereof or on the applicable redemption date, as the case may
be; (ii) in the case of Legal Defeasance, the Company shall have delivered to
the Trustee an opinion of counsel in the United States reasonably acceptable
to the Trustee confirming that (A) the Company has received from, or there has
been published by, the Internal Revenue Service a ruling or (B) since the date
of the Indenture, there has been a change in the applicable federal income tax
law, in either case to the effect that, and based thereon such opinion of

bound; (vi) the Company shall have delivered to the Trustee an officers'

MODIFICATION OF THE INDENTURE
 
  From time to time, the Company, the Guarantors and the Trustee, without the
consent of the Holders, may amend the Indenture for certain specified
purposes, including curing ambiguities, defects or inconsistencies, so long as
such change does not, in the opinion of the Trustee, adversely affect the
rights of any of the Holders in any material respect. In formulating its
opinion on such matters, the Trustee will be entitled to rely on such evidence
as it deems appropriate, including, without limitation, solely on an opinion
of counsel. Other modifications and amendments of the Indenture may be made
with the consent of the Holders of a majority in principal amount of the then
outstanding Notes issued under the Indenture, except that, without the consent
of each Holder affected thereby, no amendment may (i) reduce the amount of
Notes whose Holders must consent to an amendment; (ii) reduce the rate of or
change or have the effect of changing the time for payment of interest,
including defaulted interest, on any Notes; (iii) reduce the principal of or

or reduce the redemption or repurchase price therefor; (iv) make any Notes

Control has occurred or the subject Asset Sale has been consummated; (vii)
modify or change any provision of the Indenture or the related definitions
affecting the subordination or ranking of the Notes or any Guarantee in a
manner which adversely affects the Holders; or (viii) release any Guarantor
from any of its obligations under its Guarantee or the Indenture otherwise
than in accordance with the terms of the Indenture.
 
GOVERNING LAW
 
  The Indenture will provide that it, the Notes and the Guarantees will be
governed by, and construed in accordance with, the laws of the State of New
York but without giving effect to applicable principles of conflicts of law to
the extent that the application of the law of another jurisdiction would be
required thereby.
 
THE TRUSTEE
 
  The Indenture will provide that, except during the continuance of an Event
of Default, the Trustee will perform only such duties as are specifically set
forth in the Indenture. During the existence of an Event of
 
                                      68
<PAGE>
 
Default, the Trustee will exercise such rights and powers vested in it by the
Indenture, and use the same degree of care and skill in its exercise as a
prudent man would exercise or use under the circumstances in the conduct of
his own affairs.
 
  The Indenture and the provisions of the TIA contain certain limitations on
the rights of the Trustee, should it become a creditor of the Company, to
obtain payments of claims in certain cases or to realize on certain property
received in respect of any such claim as security or otherwise. Subject to the
TIA, the Trustee will be permitted to engage in other transactions; provided
that if the Trustee acquires any conflicting interest as described in the TIA,
it must eliminate such conflict or resign.

limitation of the foregoing, for purposes of this definition, "Consolidated
EBITDA" and "Consolidated Fixed Charges" shall be calculated after giving
effect on a pro forma basis for the period of such calculation to (i) the
incurrence or repayment of any Indebtedness of such Person or any of its

Stock) paid, accrued or scheduled to be paid or accrued during such period
times (y) a fraction, the numerator of which is one and the denominator of
which is one minus the then current effective consolidated federal, state and
local tax rate of such Person, expressed as a decimal.
 
  "Consolidated Interest Expense" means, with respect to any Person for any
period, the sum of, without duplication (i) the aggregate of the interest
expense of such Person and its Restricted Subsidiaries for such period

Subsidiary of that income is restricted by a contract, operation of law or
otherwise, (e) the net income of any Person, other than a Restricted
Subsidiary of the referent Person, except to the extent of cash dividends or
distributions paid to the referent Person or to a Wholly Owned Restricted

  Alliance does not intend to apply for listing of the Notes on a national
securities exchange. Alliance has been advised by the Underwriters that they
presently intend to make a market in the Notes, as permitted by applicable
laws and regulations. The Underwriters are not obligated, however, to make a
market in the Notes, and any such market making may be discontinued at any
time in the sole discretion of the Underwriters. There can be no assurance
that an active public market for the Notes will develop.
 
  Alliance and the Guarantors have agreed to indemnify the Underwriters
against certain liabilities, including liabilities under the Securities Act,
or to contribute to payments that the Underwriters may be required to make in
respect thereof.

  In connection with the Offering, certain persons participating in the
Offering may engage in transactions that stabilize, maintain or otherwise
affect the price of the Notes. Specifically, the Underwriters may bid for and
purchase Notes in the open market to stabilize the price of the Notes. The
Underwriters may also overallot the Offering, creating a syndicate short
position, and may bid for and purchase Notes in the open market to cover the
syndicate short position. In addition, the Underwriters may bid for and
purchase the Notes in market making transactions and impose penalty bids.
These activities may stabilize or maintain the market price of the Notes above
market levels that may otherwise prevail. The Underwriters are not required to
engage in these activities, and may end these activities at any time.

                        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.

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

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

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
       (INFORMATION AT SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1996 AND 1997 IS UNAUDITED)
 
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:

</TABLE>
 
  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.

                   SEPTEMBER 30, 1996 AND 1997 IS UNAUDITED)
 
 
  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

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
       (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

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

  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.

  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:

  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

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
       (INFORMATION AT SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1996 AND 1997 IS UNAUDITED)
 
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):
