ITEM 1. BUSINESS.
 
GENERAL
 
    Alliance Imaging, Inc. (the "Company") is a leading nationwide provider of
diagnostic imaging and therapeutic services and the largest operator of
state-of-the-art mobile diagnostic imaging systems and related outsourced
radiology services in the United States. Unless the context otherwise requires,
the term "Company" as used in this Form 10-K Annual Report refers to Alliance
Imaging, Inc., and its direct and indirect subsidiaries. The Company's
diagnostic imaging services include magnetic resonance imaging ("MRI"), computed
axial tomography ("CT"), nuclear medicine single photon emission computed
tomography ("SPECT") camera and ultrasound systems. The Company's therapeutic
services include lithotripsy, brachytherapy and microwave thermotherapy systems.
For the year ended December 31, 1998, 87.5% of the Company's revenues were
derived from MRI services.
 
    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 fixed, full-time MRI systems and services, as well as full-service
management of imaging operations for selected hospitals. The Company's MRI
services include the provision of high technology diagnostic imaging systems,
technologists to operate the imaging systems, equipment maintenance and
upgrades, the management of day-to-day operations, educational and marketing
support, patient scheduling, billing and collection services, managed care
contracting and professional liability insurance coverage. 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.
 
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 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
management expertise; or (vii) provide additional imaging services when patient
demand exceeds their in-house capability.
 
    The Company's MRI 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 December 31, 1998, the Company
provided imaging systems and related technologists and support services to 1,028
customers (873 for MRI services, 107 for CT services, and 136 for other imaging
and therapeutic modalities; some customers contract for multiple 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
December 31, 1998, the Company provided services and equipment to customers in
44 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
 
                                       2
<PAGE>
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 sales representatives
consistently seek to renew and extend contracts prior to expiration.
 
    SYSTEMS.  At December 31, 1998, the Company operated 244 MRI systems, 21 CT
systems, 11 nuclear medicine SPECT camera systems, 10 lithotripsy systems and 18
other diagnostic imaging and therapeutic systems. Of the 244 MRI systems, 191
are state-of-the-art, high-field 1.0 or 1.5 Tesla systems and 53 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
244 MRI systems, 229 are housed in mobile coaches and 15 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.
 
    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.
 
    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 or via third party vendors. 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 eight regional offices market, manage
and staff the operation of its imaging systems. The Company's regional offices
are located in Anaheim and Walnut Creek, California; Pittsburgh, Pennsylvania;
Chicago, Illinois; Colorado Springs, Colorado; Cleveland, Ohio; Berlin,
Connecticut; and Macon, Georgia. Each region has individuals responsible for
sales and operations management.
 
    LICENSING AND JCAHO ACCREDITATION.  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
 
                                       3
<PAGE>
hospitals with which it has contracted to maintain their permits, approvals and
accreditation. Each of the Company's regions has been awarded accreditation by
the JCAHO for its MRI, CT, lithotripsy and SPECT services.
 
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 volume and obtaining contract
renewals.
 
SALES AND MARKETING
 
    At December 31, 1998, the Company's sales force consisted of 15 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 also employs 40 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 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.
 
    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
 
    Most of 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, a small portion of the Company's
 
                                       4
<PAGE>
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 12.2% of the
Company's revenue in 1998.
 
    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. As described below, the Budget Reconciliation Act for 1998 mandates
implementation of a prospective payment system for hospital outpatient services.
 
    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. The
U.S. Department of Health and Human 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.
The fee schedule assigns relative value units ("RVUs") for various medical
procedures, including MRI scans. The 1994 amendments to the Social Security Act
and the 1997 Balanced Budget Act, required HHS to implement a new system for
RVUs attributable to practice expenses, with the intent of making such RVUs
reflect the relative costs actually incurred in providing various services. The
new RVUs are to be phased in over a four-year period beginning 1999. On November
2, 1998 HHS issued new RVUs, including those for MRI services; the RVUs for MRI
services are not materially different from those previously in effect.
 
    The 1998 Budget Reconciliation Act requires HHS to adopt and implement a
prospective payment system for hospital outpatient services beginning in 1999.
HHS has announced that because of the resources it is devoting to Y2K issues it
will not implement a prospective payment system for hospital outpatient services
until January 1, 2000 or later. On September 8, 1998 it issued proposed
regulations to effectuate prospective payments for hospital outpatient services.
The proposed rates could result in hospitals receiving significantly less
Medicare reimbursement for MRI services performed for Medicare outpatients
compared with reimbursement levels that would have prevailed absent any change
in law. The Company believes that approximately 15-20% of its hospital
customers' MRI revenues are derived from Medicare patients.
 
                                       5
<PAGE>
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 to 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 seven partnerships for the provision
of MRI services. The Company believes that the partnerships are 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
others, MRI services. While implementing regulations have been issued relating
to referrals for clinical laboratory services, only proposed, but not final,
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.
 
                                       6
<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.
 
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 December 31, 1998, the Company had 1,647 employees, of whom
approximately 619 were trained diagnostic imaging technologists, patient
coordinators or other technical support staff. 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.
 
COMPANY HISTORY
 
    The Company's predecessors, an English partnership and an affiliated
California corporation, began operation in 1983 by providing mobile CT services
in southern California. Mobile MRI services commenced in 1985. The Company's
predecessors were merged into Alliance Imaging plc, an English public limited
company, in 1985. The Company was incorporated in Delaware in May 1987 and in
July 1987 acquired all the outstanding stock of Alliance Imaging plc.
 
    The Company's common stock was publicly traded from August 1987 until
November 1988, when the Company was acquired in a going-private transaction. In
November 1991, the Company completed its second initial public offering of
common stock. At a Special Meeting of the Stockholders held on
 
                                       7
<PAGE>
December 17, 1997, the Company's stockholders approved the Recapitalization
Merger (as hereinafter defined) pursuant to which affiliates of Apollo
Management, L.P. ("Apollo") acquired control of the Company.
 
RECENT ACQUISITIONS
 
    On March 12, 1998, the Company acquired Mobile Technology Inc. ("MTI"), a
Los Angeles, California based provider of mobile MRI services, CT services and
other outsourced health care services. The MTI acquisition added 68 MRI systems,
3 CT systems, 9 lithotripsy systems, and 3 brachytherapy systems to the
Company's equipment fleet. The purchase price consisted of $58.3 million in cash
plus direct acquisition costs of approximately $2.0 million. In connection with
the acquisition, the Company also refinanced $37.4 million of MTI's outstanding
debt and paid MTI direct transaction costs of $3.5 million.
 
    On May 19, 1998, the Company acquired Medical Diagnostics, Inc. ("MDI"), a
Wilmington, Massachusetts based subsidiary of U.S. Diagnostic, Inc. The MDI
acquisition added 10 MRI systems (8 mobile and 2 fixed site) and 3 nuclear
medicine SPECT camera systems to the Company's equipment fleet. The purchase
price consisted of approximately $31 million in cash and the assumption of
approximately $7.4 million in financing arrangements.
 
    On November 13, 1998, two wholly owned subsidiaries of the Company acquired
all of the outstanding common stock of CuraCare, Inc. and all of the partnership
interests in American Shared-CuraCare (collectively, "American Shared") both of
which were operating subsidiaries of San Francisco, California based American
Shared Hospital Services ("ASHS"). This acquisition added 28 MRI systems, 14 CT
systems, 1 nuclear medicine SPECT camera system and 8 ultrasound systems to the
Company's equipment fleet. The purchase price included approximately $13.4
million in cash and the assumption of approximately $12.2 million in financing
arrangements, after retiring approximately $13.1 million in outstanding
indebtedness.
 
ITEM 2. PROPERTIES.
 
    The Company leases an aggregate of approximately 33,600 square feet of space
in two office buildings in Anaheim, California for its executive and principal
administrative offices. The Company also leases a 15,600 square foot operations
warehouse in Orange, California, as well as space for its other regional
offices.
 
ITEM 3. 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

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS.
 
    The Company is a leading nationwide provider of diagnostic imaging and
therapeutic 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's diagnostic imaging services include MRI, CT, SPECT
camera and ultrasound systems. The Company's therapeutic services include
lithotripsy, brachytherapy, and microwave thermotherapy systems. The Company
primarily provides MRI and CT 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 MRI services include
the provision of high technology diagnostic imaging systems, technologists to
operate the imaging systems, equipment maintenance and upgrades, the management
of day-to-day operations, educational and marketing support, patient scheduling,
billing and collection services, managed care contracting and professional
liability insurance. 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 244 MRI systems and services 1,028 customers in 44
states as of December 31, 1998.
 
    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, the Company has substantially increased
revenues by adding new customers and increasing scan volumes at existing
customer sites. The Company has also substantially increased revenue through
acquisitions. During the same period, the growth rate of the Company's EBITDA
(income before income taxes, plus depreciation, amortization and net interest
expense), excluding expenses associated with the Recapitalization Merger (as
hereinafter defined), has exceeded 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.
 
    The Company 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. The Company's ongoing equipment trade-in and upgrade
program has substantially improved the marketability and productivity of its MRI
systems. Because the Company 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. The Company currently maintains one of the
most advanced fleets in the industry.
 
    Revenues from CT services, lithotripsy services, SPECT camera services, and
other imaging services accounted for approximately 7% of the Company's revenues
for the year ended December 31, 1998.
 
                                       11

    On November 21, 1997, the Company acquired Medical Consultants Imaging Co.
("MCIC"), a Cleveland, Ohio based provider of mobile MRI services, CT services
and other outsourced health care services. The acquisition also included MCIC's
one-half interest in a limited liability company in Michigan. The purchase price
consisted of $12.3 million cash plus the assumption of approximately $5.5
million in financing arrangements. MCIC operated 14 mobile MRI systems and
several other diagnostic imaging systems, primarily in Ohio, Michigan, Indiana
and Pennsylvania.
 
    On December 18, 1997, after obtaining the approval of stockholders, the
Company completed a series of transactions contemplated by an Agreement and Plan
of Merger between Newport Investment LLC (the "Investor") and the Company (the
"Recapitalization Merger") whereby the Company: obtained proceeds from debt
financing aggregating $215.0 million; issued 150,000 shares of non-voting
redeemable Series F preferred stock to the Investor for proceeds of $15.0
million; issued 3,632,222 shares of its common stock in exchange for all of the
outstanding stock of Newport Acquisition Corporation, a subsidiary of the
Investor, and received net proceeds of $40.0 million from cash placed into
Newport Acquisition Corporation by the Investor; and converted all shares of its
common stock held by existing stockholders in excess of 411,358 shares that were
retained by electing existing stockholders into the right to receive $11 in
cash.
 
    As a result of these transactions, the Company experienced an approximate
90% ownership change. The Investor, which was formed and is wholly owned by
certain affiliates of Apollo obtained ownership of approximately 83.6% of the
Company's outstanding common stock, and the Company became highly leveraged.
 
    On March 12, 1998, the Company acquired MTI, which management believes was
the second largest provider of mobile MRI services in the United States, in a
transaction accounted for as a purchase. The Company has included the operations
of MTI in its consolidated financial statements from the date of acquisition.
This acquisition added 68 MRI systems operating in 31 states, 3 CT systems, 9
lithotripsy systems, and 3 brachytherapy systems to the Company's equipment
fleet. The purchase price consisted of $58.3 million for all of the equity
interests in MTI plus direct acquisition costs of approximately $2.0 million. In
connection with the acquisition, the Company also refinanced $37.4 million of
MTI's outstanding debt and paid MTI direct transaction costs of $3.5 million. To
finance these expenditures, the Company increased its existing term loan
facility by $20.0 million to provide total availability of $70.0 million,
established a new $50.0 million term loan facility and borrowed an aggregate of
$90.0 million thereunder, for which the Company incurred debt issuance costs of
approximately $2.8 million. The Company also borrowed $5.4 million under its
revolving loan facility and used $8.5 million of cash on hand at MTI to complete
the financing requirements. The goodwill recorded as a result of this
acquisition was $6.0 million which is being amortized on a straight-line basis
over 20 years. Additionally, the Company assigned $67.2 million of purchase
price to customer contracts and $2.9 million of purchase price to assembled work
force. The amounts are being amortized on a straight-line basis over 20 and four
years respectively. The allocation of the intangible assets acquired was based
on an independent valuation study.
 
    On May 19, 1998, the Company acquired MDI, a subsidiary of U. S. Diagnostic,
Inc. The purchase price consisted of approximately $31.0 million plus the
assumption of approximately $7.4 million in financing arrangements. The Company
borrowed $30.0 million under its revolving loan facility to finance the
transaction. The acquisition has been accounted for as a purchase and,
accordingly, the results of operations of MDI have been included in the
Company's consolidated financial statements from the date of acquisition. The
goodwill recorded as a result of this acquisition was $17.2 million which is
being amortized on a straight-line basis over 20 years. Additionally, the
Company assigned $8.3 million of purchase price to customer contracts and $0.4
million of purchase price to assembled work force. The amounts are being
amortized on a straight-line base over 20 and four years respectively. The
allocation of the intangible assets acquired was based on an independent
valuation study.
 
    On November 13, 1998, the Company acquired American Shared. The purchase
price consisted of approximately $13.4 million in cash plus the assumption of
approximately $12.2 million in financing
 
                                       12
<PAGE>
arrangements. In connection with the acquisition, the Company also refinanced
$13.1 million of American Shared's outstanding debt. The Company borrowed $30.0
million under a new tranche C term loan facility to finance the transaction. The
transaction has been accounted for as a purchase and, accordingly, the results
of operations of American Shared have been included in the Company's
consolidated financial statements from the date of acquisition. The goodwill
recorded as a result of this acquisition was approximately $30.4 million which
is being amortized on a straight-line basis over 20 years. The allocation of the
American Shared purchase price is tentative pending completion of fair value
determinations for the net assets acquired. The allocation may change with the
completion of these determinations.
 
RESULTS OF OPERATIONS
 
YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997
 
    Revenues for 1998 were $199.4 million, an increase of $112.9 million, or
130.6%, over 1997, primarily due to the MTI and MDI acquisitions. The remaining
increase reflects higher scan-based MRI revenue, MRI revenue under fixed fee
contracts and other revenue items (including revenue for other modalities).
Overall, MRI revenue increased $94.9 million, as a result of a 121.3% increase
in total scan volume partially offset by a 0.67% decrease in the average revenue
realized per MRI scan. The average daily scan volume per MRI system increased
15.3% to 8.3 from 7.2 in 1997. Management attributes the non-acquisition 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 continuing positive 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 in incremental scan volume; 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. Other revenue increased $18.0 million, or 251.5% partly due to a $6.2
million increase in lithotripsy revenue associated with the MTI acquisition, as
well as a $6.0 million increase in contract management service revenue as a
result of the Company commencing these service arrangements primarily in
connection with the MCIC acquisition. The remainder of the increase in other
revenue was primarily due to an increase in nuclear medicine revenue.
 
    The Company operated 244 MRI systems at December 31, 1998 compared to 121
MRI systems at December 31, 1997. The increase was primarily a result of the MTI
acquisition and to a lesser degree the American Shared and MDI acquisitions.
 
    Operating expenses, excluding depreciation, totaled $97.2 million in 1998,
an increase of $58.2 million, or 149.2% from 1997. Payroll and related employee
expenses increased $18.6 million, or 132.5%, primarily as a result of
acquisitions, an increase in operating staffing levels necessary to support new
units in operation and increased scans per unit. Preventative maintenance and
cryogen expense increased $9.0 million, or 97.7%, due to an increase in the
number of systems in service and the expiration of warranties on an increased
number of MRI systems. Equipment rental expense increased $8.6 million, or
276.5%, resulting from a higher number of leased MRI systems in operation and
the Company's leasing of 25 new tractors during the third quarter of 1997.
Medical supplies expense increased $2.7 million, or 334.5%, primarily as a
result of the increased level of nuclear medicine operations. Expenses
associated with contract management services increased $3.6 million as a result
of the Company commencing these service arrangements primarily in connection
with the MCIC acquisition.
 
    Depreciation expense during 1998 totaled $27.0 million, an increase of $11.0
million, or 68.6% from the 1997 level principally due to a higher amount of
depreciable assets associated with equipment additions and upgrades and
equipment acquired through acquisitions. Amortization expense during 1998
increased $5.6 million, or 230.2%, over 1997 as a result of the acquisitions
made during 1998.
 
    Selling, general and administrative expenses totaled $19.1 million in 1998,
an increase of $10.2 million or 115.6%, from 1997. Payroll and related expenses
increased $5.0 million, or 92.4%, primarily as a result
 
                                       13
<PAGE>
of increased employee compensation related to increased staffing levels
necessary to support the Company's increased level of operations. Bad debt
expense increased $3.3 million primarily as a result of the growth in revenues
and the application of the Company's more conservative bad debt reserve policy
to the acquired MTI and MDI operations.
 
    The transaction related costs primarily represent a special non-recurring
bonus paid in connection with the MTI acquisition, internal-use software
development costs associated with accounting and billing systems conversions of
the acquired companies, and a provision for bad debt conforming accounting
adjustment made in connection with the American Shared acquisition.
 
    Interest expense of $35.5 million in 1998 was $27.7 million, or 354.5%,
higher than 1997, as a result of higher average outstanding debt balances during
1998 as compared to 1997. This increase was primarily related to debt incurred
in connection with the Recapitalization Merger and the MTI and MDI acquisitions.
 
    An income tax provision of $5.0 million was recorded in 1998, resulting in
an effective tax rate of 50.5%. An income tax provision of $1.7 million was
recorded in 1997, primarily as a result of permanently non-deductible costs for
tax purposes associated with the Recapitalization Merger. At December 31, 1998,
the Company had approximately $104.4 million of net operating losses available
for federal tax purposes to offset future taxable income, subject to certain
limitations.
 
    The Company's income before extraordinary loss was $4.9 million in 1998
compared to loss before extraordinary gain of $5.7 million in 1997, an increase
of $10.6 million, primarily attributable to the non-recurring nature of the 1997
recapitalization merger costs partially offset by increased interest,
depreciation, and amortization costs and transaction related costs. The Company
reported an extraordinary loss of $2.3 million, net of income tax benefit, on
early extinguishment of debt in 1998. The Company reported an extraordinary
gain, net of income taxes, in 1997 of $1.8 million, on early extinguishment of
debt. The earnings per common share calculations reflect preferred dividend
requirements and financing fee accretion of $2.2 million in 1998 and $0.6
million in 1997.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
    Revenues for 1997 were $86.4 million, an increase of $18.0 million or 26.3%
($1.0 million, or 5.7%, as a result of the MCIC acquisition), over 1996. This
increase reflects a scan-based MRI revenue increase of $15.6 million, or 25.9%,
resulting from a 30.0% increase in total scan volume partially offset by a 3.2%
decrease in the average revenue realized per MRI scan. The average daily scan
volume per MRI system increased 8.4% to 7.24 from 6.68 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 in incremental scan volume; 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 $1.1 million, or 31.2%, as a result of internal
growth and the fourth quarter 1996 acquisition of a small CT business. Other
revenues increased $1.3 million 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, and the MCIC acquisition.
 
    The Company operated 121 MRI systems at December 31, 1997 compared to 86 MRI
systems at December 31, 1996. The average number of MRI systems operated by the
Company was 95 during 1997, compared to 85 during 1996.
 
    Operating expenses, excluding depreciation, totaled $39.0 million in 1997,
an increase of $6.7 million, or 20.6% from 1996. Payroll and related employee
expenses increased $3.1 million, or 23.3%, primarily as
 
                                       14
<PAGE>
a result of an increase in operating staffing levels necessary to support new
units in operation and increased scans per unit. Repairs and maintenance expense
increased $0.6 million, or 38.1%, due to an increased number of systems in
service, as well as costs associated with preparing additional sites. Fuel and
other vehicle expenses collectively increased $0.6 million, or 34.0%, primarily
due to addition of new MRI and other mobile systems. Preventative maintenance
and cryogen contract expense increased $0.6 million, or 6.3%, 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, employee and professional services) increased $1.8 million, or
25.8%, as a result of the increased level of operations.
 
    Depreciation expense during 1997 totaled $16.0 million, an increase of $3.3
million, or 25.6%, from the 1996 level principally due to a higher amount of
depreciable assets associated with equipment additions and upgrades.
Amortization expense during 1997 increased $0.5 million, or 24.3%, over 1996 as
a result of goodwill amortization associated with recent business acquisitions.
 
    Selling, general and administrative expenses totaled $8.9 million in 1997,
an increase of $0.7 million, or 8.9%, from 1996. Employee expenses increased
$0.4 million, or 96.8%, primarily as a result of the Company's recapitalization
effort. Professional services expenses increased $0.1 million, or 20.3%,
primarily due to costs associated with increased investor relations efforts and
merger and acquisition activity. Corporate office expenses increased $0.07
million, or 10.1%, over 1996 as a result of the Company relocating its
administrative office. Other expenses increased by $0.09 million primarily as a
result of expanded marketing programs.
 
    Interest expense of $7.8 million in 1997 was $2.1 million, or 35.6%, higher
than 1996, as a result of higher average outstanding debt balances during 1997
as compared to 1996. This increase was primarily related to the debt incurred in
connection with the Recapitalization Merger and to the financing of several new
imaging systems during 1997.
 
    An income tax provision of $1.7 million was recorded in 1997, primarily as a
result of permanently non-deductible costs for tax purposes associated with the
Recapitalization Merger. At December 31, 1997, the Company had approximately
$36.0 million of net operating losses available for federal tax purposes to
offset future taxable income, subject to certain limitations.
 
    The Company's loss before extraordinary gain was $5.7 million in 1997,
compared to income before extraordinary gain of $6.5 million in 1996, a decrease
of $12.2 million, primarily attributable to costs associated with the
Recapitalization Merger. The Company reported extraordinary gains, net of income
taxes, in 1997 of $1.8 million on early extinguishment of debt.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company generated $31.5 million, $12.9 million and $21.7 million from
operating activities in 1998, 1997, and 1996, respectively. Capital
expenditures, consisting primarily of new equipment purchases, totaled $68.7
million, $51.8 million, and $34.4 million in 1998, 1997, and 1996, respectively.
In 1998, the Company purchased 39 new MRI systems, including replacement
systems. The Company expects to purchase additional equipment under binding
commitments in 1999 and finance such purchases with the Company's Revolving Loan
Facility.
 
    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 expects capital expenditures to be
approximately $75.0 million in 1999, which primarily reflects the anticipated
purchase of 40 new MRI systems, including replacement systems, many of which
were acquired with American Shared. 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.
 
                                       15
<PAGE>
    As a result of the Recapitalization Merger, the Company issued $185.0
million of Notes (consisting of $140.0 million Senior Subordinated Notes due
2005, bearing interest at the rate of 9 5/8% per annum; and $45.0 million
Floating Interest Rate Subordinated Term Securities due 2005, bearing interest
at a rate per annum equal to LIBOR plus 4.19%) which are payable semiannually,
and require no principal repayments until maturity. The Company also entered
into a $125.0 million Credit Agreement consisting of a $50.0 million Term Loan
Facility and a $75.0 million Revolving Loan Facility, and carried over
approximately $12.7 million of other obligations. The Term Loan matures on the
sixth anniversary of the initial borrowing and requires annual principal
repayments of one percent per year during the first five years and the
outstanding principal amount in the sixth year. The Revolving Loan Facility
matures on the fifth anniversary of the initial borrowing and has mandatory
commitment reductions of $40.0 million on the fourth and fifth anniversaries of
the initial borrowing. The Credit Agreement contains restrictive covenants,
which, among other things, limit the incurrence of additional indebtedness,
dividends, transactions with affiliates, asset sales, acquisitions, mergers and
consolidations, liens and encumbrances, and prepayments of other indebtedness.
In addition, the Credit Agreement requires 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.
Subsequent amendments to the Credit Agreement are described below.
 
    Also as part of the Recapitalization Merger, the Company issued $15.0
million of Series F Preferred Stock. The Series F Preferred Stock pays dividends
at the rate of 13.5% per annum, payable quarterly in arrears, with such
dividends payable in kind for the first five years from the issue date and
thereafter in cash. 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 redeem the Series F Preferred Stock
prior to the mandatory redemption date.
 
    On November 21, 1997, the Company acquired MCIC, a Cleveland, Ohio based
provider of mobile MRI services, CT services and other outsourced health care
services. The acquisition also included MCIC's one-half interest in a limited
liability company in Michigan. The purchase price consisted of $12.3 million
cash plus the assumption of approximately $5.5 million in financing
arrangements. MCIC operated 14 mobile MRI systems and several other diagnostic
imaging systems, primarily in Ohio, Michigan, Indiana and Pennsylvania.
 
    On March 12, 1998, the Company acquired MTI, another nationwide provider of
diagnostic imaging services. The Company funded the MTI acquisition with $20.0
million of existing Term Loan availability under tranche A, $5.4 million of
revolver borrowings, a $20.0 million increase to the Term Loan Facility under
tranche A, and a new $50.0 million Term Loan Facility under tranche B. The
Credit Agreement was amended to provide for the increased Term Facilities.
 
    On May 19, 1998, the Company acquired MDI, a subsidiary of U. S. Diagnostic,
Inc. The Company borrowed $30.0 million under its Revolving Loan Facility to
finance the transaction.
 
    On September 24, 1998, the Company completed a $90.0 million expansion of
its Credit Agreement. The transaction added a new $85.0 million Term Loan
Facility under tranche C and increased the Revolving Loan Facility to $80.0
million ($22.4 million of which was funded at December 31, 1998). The total
amount outstanding under the Term Loan Facility at December 31, 1998 was $203.8
million. The increased Loan Facilities provided funds to complete the American
Shared acquisition and will also provide funds for future acquisitions and
capital expenditures.
 
    On November 13, 1998, the Company acquired American Shared. The purchase
price consisted of approximately $13.4 million plus the assumption of
approximately $12.2 million in financing arrangements.
 
                                       16
<PAGE>
In connection with the acquisition, the Company also refinanced $13.1 million of
American Shared's outstanding debt. The Company borrowed $30.0 million under the
tranche C Term Loan Facility to finance the transaction.
 
    The Company believes that 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.
 
    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.

YEAR 2000 COMPLIANCE
 
    The following disclosure is a Year 2000 readiness disclosure statement
pursuant to the Year 2000 Readiness and Disclosure Act. The Company has
implemented a process to address its Year 2000 compliance issues. The process
includes: (i) an inventory and assessment of the compliance of essential systems
and equipment of the Company and of Year 2000 mission critical suppliers,
customers, and other third parties, (ii) the remediation of non-compliant
systems and equipment, and (iii) contingency planning. The Company has completed
its inventory of imaging and therapeutic systems and has completed approximately
80% of its inventory of information systems. The Company has identified its
mission critical suppliers, customers and other third parties and is in the
process of communicating with them about their Year 2000 readiness plans and
progress. During 1998, the Company purchased Year 2000 compliant financial
reporting software which has been successfully implemented. As a result, the
Company does not believe that its financial reporting, wholesale billing, or
accounts receivable functions will be adversely affected by Year 2000 concerns.
The cost of this software was approximately $1.0 million, including
installation.
 
    The Company has also been working closely with the original equipment
manufacturers ("OEM") of its imaging and therapeutic systems to address Year
2000 concerns. Approximately 98% of the Company's MRI and CT systems will be
made compliant on a timely basis by the OEMs pursuant to the Company's existing
maintenance contracts. The Company can not currently estimate the additional
costs that will be incurred to address Year 2000 concerns. The Company's
analysis of its Year 2000 efforts are ongoing and its overall plan and cost
estimations will continue to evolve, as new information becomes available.
 
    The failure of the Company, its mission critical suppliers, customers or
third parties to be fully Year 2000 compliant for essential systems and
equipment by January 1, 2000 could result in interruptions in normal business
work operations. The Company's potential risks include: (i) the inability to
deliver
 
                                       17
<PAGE>
imaging and therapeutic services, (ii) the delayed receipt of payments from
clients or fiscal intermediaries, (iii) the failure of security systems,
elevators, heating systems and other operational systems in the Company's
offices and (iv) the inability to receive critical equipment from vendors. Each
of these events could have a material adverse effect on the Company's business,
results of operations and financial condition.
 
    Contingency plans for Year 2000 related issues continue to be developed and
include, but are not limited to, identification of alternate suppliers,
alternate equipment and manual systems. However, any contingency plan
implemented by the Company may not succeed or may not be adequate to meet the
Company's needs without materially affecting the Company's business, results of
operations or financial condition.

single industry segment, the provision of outsourced high technology diagnostic
imaging and therapeutic systems and related technical support services, as well
as management and information services, to hospitals and other health care
providers. Diagnostic imaging services are provided on both a mobile,
shared-user basis as well as on a full-time basis to single customers. The
Company 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 the Company 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 Imaging, Inc. and its
consolidated subsidiaries. Significant intercompany transactions have been
eliminated. The Company owns 49% of a partnership as a general and limited
partner and a 50% interest in two limited liability companies. These entities
provide services similar to the Company's activities and are accounted for under
the equity method.
 
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.
 
RECAPITALIZATION MERGER--On December 18, 1997, after obtaining the approval of
stockholders, the Company completed a series of transactions contemplated by an
Agreement and Plan of Merger between Newport Investment LLC (the "Investor") and
the Company (the "Recapitalization Merger") whereby the Company: obtained
proceeds from debt financing aggregating $215,000; issued 150,000 shares of non-
voting redeemable Series F preferred stock to the Investor for proceeds of
$15,000; issued 3,632,222 shares of its common stock in exchange for all of the
outstanding stock of Newport Acquisition Corporation, a subsidiary of the
Investor, and received net proceeds of $40,000 from cash placed into Newport
Acquisition Corporation by the Investor; and converted all shares of its common
stock held by existing stockholders in excess of 411,358 shares that were
retained by electing existing stockholders into the right to receive $11 in
cash. The Company used the cash proceeds from these transactions to fund: the
purchase of its common stock from existing stockholders--$162,500; repayment of
existing debt, net of $1,100 net discount on prepayment of debt--$73,900;
transaction costs charged to expense--$16,400; deferred debt financing fees and
redeemable preferred stock financing fees of $14,300; and an increase in the
Company's cash balance of $2,900.
 
    As a result of these transactions, the Company experienced an approximate
90% ownership change. The Investor, which was formed and is wholly owned by
certain affiliates of Apollo Management, L.P., ("Apollo") obtained ownership of
approximately 83.6% of the Company's outstanding common stock, and the Company
became highly leveraged. The Company paid $3,200 to Apollo for professional
services rendered in connection with the Recapitalization Merger. The
Recapitalization Merger and related transactions have been treated as a
leveraged recapitalization in which the issuance and retirement of debt have
been accounted for as financing transactions, the sales and purchases of the
Company's stock have been accounted for as capital transactions at amounts
received from or paid to stockholders, and no changes were made to the carrying
values of the Company's assets and liabilities that were not directly impacted
by the transactions.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
CASH AND SHORT-TERM INVESTMENTS--The Company considers short-term investments
with original maturities of three months or less to be cash equivalents.
 
ACCOUNTS RECEIVABLE--The Company provides shared and single-user diagnostic
imaging equipment and technical support services to the health care industry and
directly to patients on an outpatient basis. Substantially all of the Company's
accounts receivable are due from hospitals, other health care providers and
health insurance providers located throughout the United States. Services are
generally provided pursuant to long-term contracts with hospitals and other
health care providers or directly to patients, and generally collateral is not
required. Receivables generally are collected within industry norms for third-
party payors. Credit losses are provided for in the consolidated financial
statements and losses experienced have been within management's estimates.
 
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 between five and twenty percent of
original cost. If the Company 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 and
leasehold improvements, substantially all of the property owned by the Company
relates to diagnostic imaging equipment, tractors and trailers used in the
business.
 
GOODWILL--The Company amortizes goodwill using the straight-line method over a
period of one to twenty-five years. For acquired entities, the amortization
period selected is primarily based upon the estimated life of the customer
contracts, including expected renewals, and other related assets acquired, not
to exceed twenty years. The Company reviews its long-lived assets and related
intangibles for impairment whenever events or changes in circumstances indicate
that the carrying amount of an asset may not be recoverable. The recoverability
test is performed at the lowest level at which undiscounted net cash flows can
be directly attributable to long-lived assets.
 
REVENUE RECOGNITION--The majority of the Company's revenues are derived directly
from health care providers. To a lesser extent, 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 less than
established patient billing rates. Net revenues from direct patient billing
amounted to approximately 12%, 7% and 8% of revenues in the years ended December
31, 1998, 1997 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, 1998. All revenues are recognized at the time the service is
performed.
 
INCOME TAXES--The Company calculates deferred taxes and related income tax
expense using the liability method. This method determines deferred taxes by
applying the current tax rate to the cumulative temporary differences between
recorded carrying amounts and the corresponding tax basis of assets and
liabilities. A valuation allowance is established for deferred tax assets unless
their realization is considered

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
more likely than not. The Company'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--The Company accounts for investment tax credits under
the flow through method.
 
FAIR VALUES OF FINANCIAL INSTRUMENTS
 
    The following methods and assumptions were used by the Company 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 the Company's long-term debt are
estimated using discounted cash flow analyses, based on the Company's current
incremental rates for similar types of borrowing arrangements.
 
    REDEEMABLE PREFERRED STOCK:  As more fully discussed in Note 5, the Company
issued its Series F redeemable preferred stock in exchange for $15,000 cash on
December 18, 1997, in connection with the Recapitalization Merger. Although it
was not practicable to reevaluate the estimated fair value of the Series F
redeemable preferred stock as of December 31, 1998 and 1997 because of a lack of
a quoted market price and the inability to estimate fair value without incurring
excessive costs, the Company believes the carrying amounts as of December 31,
1998 and 1997 of $16,673 and $14,487, which represent the original fair value of
the preferred stock (less a $600 financing fee) increased for the 1998 and 1997
cumulative dividends and financing fee accretion, reasonably approximate its
fair value at those dates.
 
    Accordingly, the carrying amounts and estimated fair values of the Company's
financial instruments are as follows:

RECENT ACCOUNTING PRONOUNCEMENTS--Effective January 1, 1998, the Company adopted
Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" ("FAS 130"), which establishes standards for reporting and displaying
comprehensive income and its components in the financial statements. For the
years ended December 31, 1998 , 1997 and 1996, the Company did not have any
components of other comprehensive income as defined in FAS 130.
 
3. ACQUISITIONS
 
    On March 12, 1998, the Company acquired Mobile Technology Inc. ("MTI"),
which management believes was the second largest provider of mobile MRI services
in the United States, in a transaction accounted for as a purchase. The Company
has included the operations of MTI in its consolidated financial statements from
the date of acquisition. The purchase price consisted of $58,300 for all of the
equity interests in MTI plus direct acquisition costs of approximately $2,000.
In connection with the acquisition, the Company also refinanced $37,400 of MTI's
outstanding debt and paid MTI direct transaction costs of $3,500. The goodwill
recorded as a result of this acquisition was $5,979 which is being amortized on
a straight-line basis over 20 years. Additionally, the Company assigned $67,200
of purchase price to customer contracts and $2,870 of purchase price to
assembled work force. The amounts are being amortized on a straight-line basis
over 20 and four years respectively. The allocation of the intangible assets
acquired was based on an independent valuation study.

3. ACQUISITIONS (CONTINUED)
    On May 19, 1998, the Company acquired Medical Diagnostics, Inc. ("MDI"), a
subsidiary of U. S. Diagnostic, Inc. The purchase price consisted of
approximately $31,000 plus the assumption of approximately $7,400 in financing
arrangements. The transaction has been accounted for as a purchase and,
accordingly, the results of operations of MDI have been included in the
Company's consolidated financial statements from the date of acquisition. The
goodwill recorded as a result of this acquisition was $17,212 which is being
amortized on a straight-line basis over 20 years. Additionally, the Company
assigned $8,300 of purchase price to customer contracts and $350 of purchase
price to assembled work force. The amounts are being amortized on a
straight-line basis over 20 and four years respectively. The allocation of the
intangible assets acquired was based on an independent valuation study.
 
    On November 13, 1998, two wholly owned subsidiaries of the Company acquired
all of the outstanding common stock of CuraCare, Inc. and all of the partnership
interests in American Shared-CuraCare (collectively, "American Shared"). The
purchase price consisted of approximately $13,377 plus the assumption of
approximately $12,241 in financing arrangements. In connection with the
acquisition, the Company also refinanced $13,130 of American Shared's
outstanding debt. The transaction has been accounted for as a purchase and,
accordingly, the results of operations of American Shared have been included in
the Company's consolidated financial statements from the date of acquisition.
The goodwill recorded as a result of this acquisition was approximately $30,445
which is being amortized on a straight-line basis over 20 years. The allocation
of the American Shared purchase price is tentative pending completion of fair
value determinations for the net assets acquired. The allocation may change with
the completion of these determinations.
 
    On November 21, 1997, the Company acquired Medical Consultants Imaging Co.
("MCIC"), a Cleveland, Ohio based provider of mobile MRI services, CT services
and other outsourced health care services. The acquisition also included MCIC's
one-half interest in a limited liability company in Michigan. The purchase price
consisted of approximately $12,300 in cash (of which $2,000 has been placed in
escrow and is subject to certain reductions) plus the assumption of
approximately $5,500 in financing arrangements. The acquisition has been
accounted for as a purchase and, accordingly, the results of operations of MCIC
have been included in the Company's consolidated financial statements from the
date of acquisition. The goodwill recorded as a result of this acquisition was
$10,932, which is being amortized on a straight-line basis over 20 years.
 
    On April 26, 1996, the Company acquired all of the outstanding shares of
Royal Medical Health Services, Inc. ("Royal") of Pittsburgh, Pennsylvania. Like
the Company, Royal is a provider of comprehensive MRI services. The Company
issued 3,876 shares of Series C convertible preferred stock valued at $388,
common stock warrants valued at $212, and paid $1,914 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 the Company's consolidated financial statements from
the date of acquisition.
 
    The unaudited pro forma information below presents combined results of
operations as if the MTI, MDI and American Shared acquisitions had occurred at
the beginning of 1998 and 1997, and as if the MCIC acquisition had occurred at
the beginning of 1997 and 1996 and the Royal acquisition had occurred at the
beginning of 1996. The unaudited pro forma information is not necessarily
indicative of the results

of 9.625% senior subordinated notes and $45,000 of floating interest rate
subordinated term securities (collectively, the "Notes"). The Notes mature on
December 15, 2005 and are unsecured obligations of the Company ranking
subordinate in right of payment to all senior debt. Interest on the Notes is
payable semi-annually in cash on each June 15 and December 15 commencing on June
15, 1998. The interest rate on the floating interest rate subordinated term
securities was 9.2881% and 10.09625% at December 31, 1998 and 1997,
respectively.

4. INDEBTEDNESS (CONTINUED)
    The Notes are unconditionally guaranteed, on a senior subordinated basis,
jointly and severally, by all significant direct and indirect consolidated
subsidiaries of the Company, which consist of Royal Medical Health Services,
Inc., Alliance Imaging of Central Georgia, Inc., Alliance Imaging of Ohio, Inc.,
Alliance Imaging of Michigan, Inc., Mobile Technology Inc., Medical Diagnostics,
Inc., Central Massachusetts MRI Services, Inc., Western Massachusetts Magnetic
Resonance Services, Inc., Embarcadero Holding Corp. I, Embarcadero Holding Corp.
II and Curacare, 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 the
Company's obligations pursuant to the Notes, and the aggregate net assets,
earnings and equity of the Subsidiary 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 and other disclosures concerning the Subsidiary Guarantors
would not provide material information to users of its financial statements.
Combined summarized financial information for the Subsidiary Guarantors is set
forth below:

    In addition to the Notes, in December 1997 the Company also entered into a
Credit Agreement with a bank consisting of a $50,000 term loan facility and a
$75,000 revolving loan facility. On March 12, 1998, the Company increased its
term loan facility by $70,000 by increasing its existing tranche A term loan
facility by $20,000 and establishing a new $50,000 tranche B term loan facility.
In connection with this transaction, the Company recorded an extraordinary loss

debt. On September 24, 1998, the Company completed a $90,000 expansion of its
Credit Agreement. The transaction added a new $85,000 tranche C term loan
facility and increased the revolving loan facility to $80,000. In connection
with this transaction, the Company recorded an extraordinary loss of $1,471, net
of income tax benefit, on early extinguishment of debt. Interest under the term
loan facility and revolving loan facility is variable based on the Company's
leverage ratio and changes in specified published rates and the bank's prime
lending rate. The weighted average interest rate on the term loan facility was
7.68% and 8.41% at December 31, 1998 and 1997, respectively. The revolving loan
facility balance was $22,394 and zero at December 31, 1998 and 1997,
respectively. The weighted average interest rate on the revolving loan facility
was 7.47% at December 31, 1998.
 
    In addition to a variable per annum fee in respect of outstanding letters of
credit, the Company also pays a commitment fee equal to 1/2 of 1% per annum on
the undrawn portion available under the Credit Agreement subject to decreases in
certain circumstances. Certain mandatory prepayments are required from proceeds
of various transactions and are allocated first to the term loan facility.
Voluntary prepayments are permitted subject to certain limitations.
 
    The term loan facility, the revolving loan facility, and the obligations to
lending institutions are collateralized by all of the Company's equipment at
December 31, 1998 and 1997.

5. PREFERRED AND COMMON STOCK
 
PREFERRED STOCK--The Company is authorized to issue 500,000 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 the Recapitalization Merger (SEE NOTE 1), the Company
authorized 300,000 shares of a new Series F redeemable preferred stock on
December 18, 1997. The stock was recorded at $14,400 (liquidation value of
$15,000 less a financing fee of $600). The financing fee is being accreted on a
straight-line basis over the ten-year term of the stock. The holders of the
Series F redeemable preferred stock are entitled to receive cumulative dividends
at the rate of 13.5% per annum of the stated liquidation value. Unpaid dividends
accumulate and are payable quarterly by the Company in kind for the first five
years after issuance, and thereafter in cash.

                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
5. PREFERRED AND COMMON STOCK (CONTINUED)
    In the event of liquidation, dissolution or winding up of the Company, the
holders of Series F redeemable 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. The Series
F redeemable preferred stock is redeemable at the option of the Company at
stated redemption premiums from the date of issuance through December 31, 2007.
The Company is required to redeem all outstanding shares of Series F redeemable
preferred stock at 100% of liquidation value on December 31, 2007 out of funds
legally available. No sinking fund has been or will be established for the
retirement or redemption of the shares of Series F redeemable preferred stock.
Series F preferred stock is not convertible into shares of any other class or
series of capital 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--The Company 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" ("FAS 123") 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 the Company's employee stock options equals the market price
of the underlying stock on the date of grant, no compensation expense is
recognized.
 
    The Company'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 3 to 4 years of continued
employment. In connection with the Recapitalization Merger, the Company adopted
a new employee stock option plan pursuant to which options with respect to a
total of 454,545 shares of the Company's common stock will be available for
grant. Options are granted at their fair value at the date of grant. All options
have 10 year terms. Fifty percent of the options vest in equal increments over
four years and fifty percent vest over seven and one-half years (subject to
acceleration if certain per-share equity targets are achieved). The
weighted-average remaining contractual life of options outstanding as of

    At December 31, 1998, 30,000 of these options were exercisable at $3.5625;
10,969 were exercisable at $6.5625; 412,045 were exercisable at $11.00; and
38,500 were exercisable at $16.50.
 
    In addition, the Company had options on 40,000 shares of common stock
outstanding at December 31, 1996 at exercise prices of $1.125 to $8.25 and
granted options on an additional 100,000 shares of common stock in 1997 at
exercise prices of $6.5625 to $7.875 per share. These stock options were granted
to Company directors outside of the 1991 Stock Option Plan and were all redeemed
for cash in connection with the Recapitalization Merger (SEE NOTE 1).
 
    FAS 123 requires presentation of pro forma information regarding net income
and earnings per share determined as if the Company 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 the Black-Scholes option pricing model with the
following weighted-average assumptions for 1998, 1997 and 1996, respectively:
risk-free interest rates of 5.23%, 6.31% and 5.72%; no dividend yield;
volatility factors of the expected market price of the Company's common stock of
 .83, .41 and .43; and a weighted-average expected life of the options of 5.75, 7
and 7 years. The weighted-average fair value of options granted during 1998,
1997 and 1996 is $8.50, $4.60 and $1.93, respectively.
 
    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 the Company'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.
 
    For purposes of pro forma disclosures, the estimated fair value of the

8. INCOME TAXES (CONTINUED)
    In 1998, tax authorities concluded an examination of the Company's income
taxes for 1994. As a result of the conclusion of this examination, the Company
released approximately $500 of its contingency reserves for income taxes.
 
    In 1998, the Company acquired MTI, which had federal net operating loss
carryforwards of approximately $49,000. These loss carryforwards expire in years
2006 through 2011. Their utilization is subject to substantial limitations under
the Internal Revenue Code. The Company also has other net operating loss
carryforwards of approximately $55,428 and $38,336 for federal and state income
tax purposes, respectively. These loss carryforwards expire in years 2003
through 2018.
 
    The Company maintains a valuation allowance to reduce certain deferred tax
assets to amounts that are in management's estimation more likely than not to be
realized. This allowance primarily relates to the deferred tax assets
established for net operating loss carryforwards. The 1998 increase in the
valuation allowance of approximately $16,991 relates to the net operating loss
carryforwards of MTI. Any reductions in the valuation allowance resulting from
realization of the MTI net operating loss carryforwards will result in a
reduction of goodwill.
 
9. RELATED PARTY TRANSACTIONS
 
    The Company paid $3,200 to Apollo in 1997 in connection with the
Recapitalization Merger.
 
    In 1998, the Company paid Apollo an annual management fee of $500 and
expects to continue to receive financial advisory services from Apollo on an
ongoing basis, with compensation to be determined. In addition, the Company paid
to Apollo a fee of $1,000 and $460 as consideration for services rendered in
structuring and negotiating the acquisition of MTI and American Shared,
respectively, and also reimbursed Apollo for expenses of approximately $275
associated with these acquisitions.
 
    Apollo holds a controlling interest in SMT Health Services, Inc. ("SMT"), a
provider of mobile MRI services in the Mid-Atlantic region of the United States.
During 1998, a subsidiary of the Company purchased an MRI system from SMT for
$350 and a subsidiary of the Company sold an MRI system to SMT for $520. From
time to time during 1998, the Company rented MRI systems from SMT for an
aggregate of $60 and SMT rented MRI systems from the Company for an aggregate
$165. In addition, SMT assigned certain of its customer contracts to the Company
and received an aggregate assignment fee of $556 related to these contracts.

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, 1998 and 1997, and the related consolidated
statements of operations, cash flows, and preferred stock, common stock,
additional paid-in capital (deficit) and accumulated deficit for each of the

financial statement schedule listed in the Index at Item 14(a). These financial
statements and schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
schedule 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, 1998 and 1997, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended December 31, 1998, in conformity with generally accepted accounting

considered in relation to the basic financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.

    after seven and one half years (subject to acceleration if the Company
    achieves certain per-share equity targets).
 
(2) Options granted pursuant to the 1997 Stock Option Plan to the Named Officers
    were granted at an exercise price equal to the cash amount paid for shares
    of the Company's Common Stock in the Recapitalization Merger.
 
(3) Valuations based upon the assumed rates of stock price appreciation are
    based upon appreciation over a ten-year period from the $11.00 exercise
    price of the options. The 5% and 10% assumed annual rates of appreciation
    related to the options granted would result in the price of the Company's
    Common Stock increasing to $17.92 and $28.53 per share, respectively.

LONG-TERM INCENTIVE PLAN--AWARDS IN LAST FISCAL YEAR
 
    The Company instituted a long-term executive incentive plan ("LTIP") in 1995
to provide future awards in cash or equivalent amounts of Common Stock to key
executives. The objective of the plan was to advance the long-term interests of
the Company and its stockholders by providing substantial incentive to meet or
exceed certain cash-flow goals necessary to ensure that the Company 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, the Company 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 final
objective of the LTIP (the Company's actual earnings before depreciation,
amortization, interest, taxes and equipment charges, ("EBDIT") objective for
1998) was met in 1998 and final payments have been made pursuant to the LTIP.
All amounts previously earned under the LTIP were paid in cash at the time of
the Recapitalization Merger.
 
    The following awards under the plan were earned by the Named Officers in
1998:

401(K) PLAN
 
    The Company established a tax deferred savings plan (the "401(k) Plan") in
January 1990. The 401(k) Plan covers all employees who were hired before January
1, 1990 or who were subsequently employed by the Company for at least six
months. Employees contributed from 1% to 15% of their compensation to the 401(k)
Plan on a pre-tax basis, subject to statutory limitations. For up to 7% of an
employee's compensation, the Company contributed up to $0.333 for each $1.00 of
the employee's contribution. Effective August 1, 1998, the 401(k) Plan was
amended and restated in its entirety. Currently, all employees who are over 21
years of age are eligible to participate after attaining six months of service.
Employees may contribute between 1% and 15% of their annual compensation. The
Company matches 50 cents for every dollar of employee contributions up to 5% of
their compensation, subject to statutory limitations. The rates of pre-tax and
matching contributions may be reduced with respect to highly compensated
employees, as defined in the Code, so that the 401(k) Plan will comply with
Sections 401(k) and 401(m) of the Code. Pre-tax and matching contributions are
allocated to each employee's individual account, which are invested in selected
fixed income or stock managed accounts according to the directions of the
employee. An employee's pre-tax contributions are fully vested and
nonforfeitable at all times. Matching contributions vest over four years of
service. An employee may forfeit unvested amounts upon termination of
employment, unless the termination is because of death, disability or
retirement.
 
    Matching contributions made by the Company pursuant to the 401(k) Plan to
the Named Officers for the 1998, 1997 and 1996 fiscal years are included under
"All Other Compensation" in the Summary Compensation Table.

EMPLOYMENT AND CHANGE OF CONTROL ARRANGEMENTS
 
    The Company has entered into employment agreements with Messrs. Zehner, Pino
and Ord. Base compensation under these employment agreements for the year ending
December 31, 1999 has been set at $350,000 per year for Mr. Zehner, $298,000 per
year for Mr. Pino and $270,000 per year for Mr. Ord, subject in each case to
increase by the Board of Directors. In addition, Messrs. Zehner, Pino and Ord
are entitled to receive an annual cash bonus based upon the Company'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, 60% in the case of Mr. Pino and 50% in
the case of Mr. Ord). Such bonus plan will be adopted and administered by the
compensation committee of the Board of Directors.
 
    The Agreements 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. The Company may terminate Mr. Zehner's, Mr. Pino's or Mr.
Ord's employment at any time and for any reason and Mr. Zehner, Mr. Pino and Mr.
Ord may resign at any time and for any reason.
 
    The employment agreements for Messrs. Zehner and Pino were amended in
February 1998, to provide for, among other items, the payment of one-time lump
sum bonuses of $350,000 and $300,000, respectively, upon the closing of the
acquisition by the Company of MTI or another acquisition with an enterprise
valuation of $25,000,000 or more.
 
    The Company is also a party with Messrs. Andrues and Mericle and Ms. Ford to
written employment agreements. Each employment agreement remains in effect until
notice of termination is given by either party. Each contract provides that the
Named Officer will continue to receive his or her base salary and be entitled to
earn bonuses and participate in all benefit plans and programs at levels and
pursuant to terms that are substantially consistent with current levels and
terms, subject to periodic review and possible increases by the Board of
Directors or the Compensation Committee. In addition, each contract provides
that if the Named Officer is terminated by the Company other than for Just Cause
(as defined in the agreement) or if the Named Officer terminates his or her
employment as a result of a Constructive Discharge (as defined in the agreement)
(in either event, a "Severance"), then the Named Officer will be entitled to a
cash severance benefit equal to a specified number of months of salary at his or
her then current rate of salary, acceleration of the vesting of stock options
and certain other benefits identified in the contract. If such Severance were to
occur within one year prior to or following a Change of Control (as defined in
the agreement), then each employment agreement provides for an increased cash
severance benefit.
 
INDEPENDENT DIRECTOR COMPENSATION
 
    The independent directors of the Company (i.e., non-employee and non-Apollo
affiliated directors) receive a $1,000 monthly retainer; $500 for each Board or
committee meeting attended; and reimbursement of travel expenses.

                         Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware

                                 ---------------

         Alliance Imaging, Inc., a corporation organized and existing under 
the General Corporation Law of the State of Delaware (hereinafter called the 
"Corporation"), hereby certifies that the following resolution was duly 
adopted by the Board of Directors of the Corporation as required by Section 
151 of the Delaware General Corporation Law at a meeting duly called and held 
on December 18, 1997.

         RESOLVED, that one series of the class of authorized preferred 
stock, $.01 par value, of the Corporation is hereby created and that the 
designations, powers, preferences and relative, participating, optional or 
other special rights of the shares of such series, and qualifications, 
limitations or restrictions thereof, are hereby fixed as follows:

         1. NUMBER OF SHARES AND DESIGNATIONS.

         Three Hundred Thousand (300,000) of the shares of the Corporation's 
preferred stock, $.01 par value, are hereby designated the "Series F 
Preferred Stock." One Hundred Fifty Thousand (150,000) of such shares of 
Series F Preferred Stock shall be issued as of the date hereof, and the 
balance of such shares shall be authorized and reserved for issuance pursuant 
to Section 4 hereof.

         2. VOTING RIGHTS

or the Amended and Restated Certificate of Incorporation, holders of Series F

<PAGE>

         4. DISTRIBUTIONS

         The holders of shares of Series F Preferred Stock shall be entitled 
to receive when and as declared by the Board of Directors of the Corporation, 
out of funds legally available therefor, cumulative dividends on the shares 
of the Series F Preferred Stock, at the rate of 13.5% per annum on the 
Liquidation Value (as defined herein), payable quarterly in arrears on March 
31, June 30, September 30 and December 31 of each year. Dividends on the 
Series F Preferred Stock shall be payable in kind for the first five years 
after issuance, and thereafter in cash. Dividends on the Series F Preferred 
Stock shall be payable in preference to and in priority over dividends on any 
other class or series of capital stock of the Corporation, including the 
common stock of the Corporation (the "Common Stock"). Dividends shall be 
fully cumulative.

         Except as set forth in this Certificate of Designation, or to the 
extent approval is provided in writing by the holders of two-thirds of the 
outstanding shares of Series F Preferred Stock (voting as a separate class), 
the Corporation shall not, and shall not permit any Subsidiary (as defined 
herein) to, declare or pay any dividends, or purchase, redeem, retire, or 
otherwise acquire for value any shares of its capital stock (or rights, 
options or warrants to purchase such shares) now or hereafter outstanding, 
return any capital or make any distribution of assets to its stockholders, 
except that the Corporation may: (i) permit any wholly-owned Subsidiary to 
declare and make payment of cash and stock dividends, return capital and make 
distributions of assets solely to the Corporation or another wholly-owned 
Subsidiary; (ii) effect a stock split of, or declare or pay any dividend on, 
the Common Stock consisting solely of shares of Common Stock; (iii) comply 
with any specific provision of the terms of any subsequently designated 
series of Preferred Stock approved by the holders of the Series F Preferred 
Stock as provided for herein; or (iv) redeem or repurchase any stock of any 
director, officer, employee, consultant or other person or entity, pursuant 
to a stock repurchase agreement or stock restriction agreement approved by 
the board of directors under which the Corporation has the right or 
obligation to repurchase (in the event of death, termination of employment or 
of the consulting arrangement, or other similar discontinuation of a business 
relationship) vested shares at no more than their fair market value and 
unvested shares at no more than their initial issuance price. Unless 
otherwise specified herein, "Subsidiary" or "Subsidiaries" means any 
corporation, partnership or joint venture of which the Corporation or any of 
its other Subsidiaries (as herein defined) directly or indirectly owns at the 
time at least fifty percent (50%) of the outstanding voting shares or similar 
interests.

         5. LIQUIDATION, DISSOLUTION OR WINDING UP

         In the event of any liquidation, dissolution or winding up of the 
Corporation, whether voluntary or involuntary, or in the event of its 
insolvency, before any distribution or payment is made to any holders of 
Common Stock or any other class or series of capital stock of the Corporation 
designated to be junior to the Series F Preferred Stock in liquidation 
preference, and subject to the liquidation rights and preferences of any 
class or series of Preferred Stock designated in the future to be senior to, 
or on a parity with, the Series F Preferred Stock with respect to liquidation 
preference, the holders of each share of Series F Preferred Stock shall be 
entitled to be paid first out of the assets of the Corporation available for 
distribution to holders of the Corporation's capital stock of all classes, 
whether such assets are capital, surplus or earnings ("Available Assets"), an 
amount in respect of each share of Series F Preferred Stock equal to One 
Hundred Dollars ($100) plus accrued but unpaid dividends (the "Liquidation 
Value"); PROVIDED 

                                       2

<PAGE>

that such amount shall be subject to equitable adjustment for any stock 
dividend, stock split, combination, reorganization, recapitalization, 
reclassification or other similar event involving a change in the capital 
structure of the Preferred Stock.

         If, upon liquidation, dissolution or winding up of the Corporation, 
the Available Assets shall be insufficient to pay the holders of Series F 
Preferred Stock and of any other series of Preferred Stock on parity with the 
Series F Preferred Stock with respect to liquidation preference the full 
amounts to which they otherwise would be entitled, the holders of Series F 
Preferred Stock and such other series of Preferred Stock shall share ratably 
in any distribution of Available Assets pro rata in proportion to the 
respective liquidation preference amounts which would otherwise be payable 
upon liquidation with respect to the outstanding shares of the Series F 
Preferred Stock and such other series of Preferred Stock if all liquidation 
preference dollar amounts with respect to such shares were paid in full.

         6. TREATMENT OF REORGANIZATION, CONSOLIDATION, MERGER, OR SALE OF 
ASSETS.

         Any merger, consolidation or other corporate reorganization or 
combination to which the Corporation is a party, and any sale of all or 
substantially all of the assets or stock of the Corporation, shall be 
regarded, at the option of the holders of two-thirds of the outstanding 
shares of Series F Preferred Stock, as a liquidation, dissolution or winding 
up of the affairs of the Corporation for purposes of this Section 6.

         The provisions of this Section 6 shall not apply to (i) any 
reorganization, merger or consolidation involving only a change in the state 
of incorporation of the Corporation, (ii) a merger of the Corporation with or 
into a wholly-owned Subsidiary of the Corporation that is incorporated in the 
United States of America, or (iii) a merger, reorganization, consolidation or 
other combination in which the Corporation is the surviving corporation and 
operates as a going concern, with another corporation incorporated in the 
United States of America and which does not involve a recapitalization, 
reorganization, reclassification or other similar change in the capital 
structure of the Corporation after which the shareholders of the Corporation 
will own less than 50% of the capital stock of the Corporation.

         7. REDEMPTION

         The Series F Preferred Stock shall be redeemable at the option of 
the Corporation at the applicable premium to Liquidation Value set forth

               Certificate of Incorporation without the approval by vote or
               written consent of the holders of at least two-thirds of the then
               outstanding shares of Series F Preferred Stock, voting as a
               single class, each share of Series F Preferred Stock to be
               entitled to one vote in each instance, if such corporate action
               or amendment would change any of the rights, preferences,
               privileges of or limitations provided for herein for the benefit
               of any shares of Series F Preferred Stock. Without limiting the
               generality of the preceding sentence, the Corporation will not

               at least two-thirds of the then outstanding shares of Series F
               Preferred Stock, voting as a single class, if such corporate
               action would amend the Certificate of Incorporation of the
               Corporation in a way that would change any of the rights,
               preferences, privileges of or limitations provided for herein for
               the benefit of any shares of Series F Preferred Stock.

         9. NOTICES OF RECORD DATE. In the event of:

          (i)  any taking by the Corporation of a record of the holders of any
               class of securities for the purpose of determining the holders
               thereof who are entitled to receive any dividends or other
               distribution, or any right to subscribe for, purchase or
               otherwise acquire any shares of capital stock of any class or any
               other securities or property, or to receive any other right,

          (ii) any capital reorganization of the Corporation, any
               reclassification or recapitalization of the capital stock of the
               Corporation, any merger or consolidation of the Corporation, or
               any transfer of all or substantially all of the assets of the
               Corporation to any other corporation, or any other entity or
               person, or

         (iii) any voluntary or involuntary dissolution, liquidation or winding
               up of the Corporation, 

then and in each such event the Corporation shall mail or cause to be mailed 
to each holder of Preferred Stock a notice specifying (i) the date on which 
any such record is to be taken for the purpose of such dividend, distribution 
or right and a description of such dividend, distribution or right, (ii) the

                  The Corporation may from time to time, in its sole discretion,
         request that the Executive forfeit up to all of the New Options on the
         terms and conditions set forth in this Section 15.

                  (a) The Compensation Committee of the Board of Directors of

         one or more new employees of the Corporation or its subsidiaries (the
         "AGGREGATE FORFEITURE NUMBER"), and shall deliver a notice to the
         Executive to such effect.

                  (b) Immediately upon delivery of the notice referred to in 
         Section 15(a), the Executive shall be deemed to have forfeited New 
         Options (the "FORFEITED OPTIONS") as follows:

                  Options equal to the Aggregate Forfeiture Number, multiplied
                  by a fraction, the numerator of which is the number of New
                  Options held by the Executive and the denominator of which is
                  the number of options granted on the date hereof to and held
                  by Richard N. Zehner and Vincent S. Pino.

                           (ii) 50% of the Forfeited Options shall be Tranche A
                  Options, 25% of the Forfeited Options shall be Tranche B
                  Options and 25% of the Forfeited Options shall be Tranche C
                  Options.

                           (iii) Simultaneously with the delivery of the notice
                  referred to in Section 15(a), the Corporation (as directed by
                  the Compensation Committee of the Board of Directors) shall
                  cause to be issued to the Executive a number of replacement
                  options ("NON-PLAN OPTIONS") which will contain the same terms
                  and conditions as the New Options (including the continuation
                  of the same vesting schedule as the New Options) except that
                  the exercise price of the Non-Plan Options shall be equal to
                  (A) $11 plus (B) the absolute value of the difference between
                  the Fair Market Value of a Share on the date that the
                  Executive exercises the Non-Plan Option and the exercise price
                  of the option granted to another employee pursuant to Section
                  15(a) hereof which grant caused the issuance to the Executive
                  of such Non-Plan Option.

                           (iv) Promptly after receipt of the notice referred to
                  in Section 15(a), the Executive will deliver to the
                  Corporation its Option and the Corporation will cancel the
                  Option and reissue (A) a new option to the Executive for the
                  aggregate number of Options held by the Executive less the
                  number of Options forfeited by the Executive and (B) a
                  Non-Plan Option for a number of Shares equal to the number of
                  Options forfeited by the Executive.

                  Corporation the right to repurchase such Option for cash in an
                  amount equal to the Fair Market Value of each Share subject to

         2. For purposes of this letter agreement, a Competition Event shall

other business that becomes material to the Company's business during your 
employment by the Company (the "Company Business") within the United States;

have any direct or indirect financial interest, in any enterprise which has 
any material operations engaged in the Company Business within the United 
States; PROVIDED, HOWEVER, that nothing contained herein shall prohibit you

business opportunity, after obtaining approval of a majority of the Board of 
Directors of the Company and a majority of the independent members of the 
Board of Directors of the Company (if any); or (B) owning no more than five

         3. As a means reasonably designed to protect certain confidential 
information of the Company which would otherwise inherently be utilized in 
the following proscribed activities, and in partial consideration of the 
Company's covenant to make the payments described in Paragraph 5, you agree 
that you will not, prior to the date you cease to receive payments under 
Paragraph 5 below, solicit or make any other contact with, directly or 
indirectly, any customer of the Company as of the Date of Termination with 
respect to the provision of any service to any such customer that is the same 
or substantially similar to any service provided to such customer by the 
Company.

         4. In partial consideration of the Company's covenant to make the 
payments described in Paragraph 5, you agree that you will not, prior to the

the Date of Termination (or any person who was employed by the Company at any 
time during the three-month period prior to the Date of Termination) with 
respect to any employment, services or other business relationship.

         5. In partial consideration of your covenants contained herein, the 
Company shall, immediately following the Date of Termination, pay you an 
amount equal to (A) the sum of your base salary as of the Date of 
Termination, multiplied by (B) a fraction, the numerator of which is the 
greater of 365 and the number of days remaining in the Term as of the Date of 
Termination assuming the Term had not expired on the Date of Termination and 
the denominator of which is 365. All payments under this Paragraph 5 shall be 
made in equal installments on a bi-weekly basis over a period equal to the 
greater of the remaining Term (assuming the Term had not expired) or one 
year. Notwithstanding the foregoing, the Company shall not be obligated to 
make any payments under this Paragraph 5 to you if you (x) fail to cure a 
breach of this Agreement within fifteen days after receipt of notice of such 
breach from the Company, or (y) if your employment with the Company is 
terminated by reason of your death or disability or for Cause or by reason of 
your resignation other than for Good Reason.

         6. Notwithstanding paragraph 1 through 4 hereof, if the Company 
shall fail to make any payment to you that the Company is obligated to make 
pursuant to Paragraph 5 and such failure shall continue for more than five 
days after receipt of notice from you, all future payments to you under 
Paragraph 5 shall become immediately due and payable or you shall be relieved 
of all obligations under this Agreement.

shall include Alliance Imaging, Inc., its subsidiaries and/or its affiliates.

         8. You acknowledge that irreparable damage would occur in the event 
of a breach of the provisions of this Agreement by you. It is accordingly 
agreed that, in addition to any other remedy to which it is entitled at law 
or in equity, the Company shall be entitled to an injunction or injunctions 
to prevent breaches of this letter agreement and to enforce specifically the 
terms and provisions of this letter agreement.

         9. If, at the time of enforcement, any sentence, paragraph, clause, 
or combination of the same of this Agreement is in violation of the law of 
any state where applicable, such sentence, paragraph, clause, or combination 
of the same shall be void in the jurisdictions where it is unlawful, and the 
remainder of this Agreement shall remain binding on the parties. In the event 
that any part of any covenant of this Agreement is determined by a court of 
law to be overly broad thereby making the covenant unenforceable, the parties 
agree that such court shall substitute a judicially enforceable limitation in 
its place, and that as so modified, the covenants shall be binding upon the 
parties as if originally set forth in this Agreement.

                              EMPLOYMENT AGREEMENT


         THIS AGREEMENT is made and entered into as of April 29, 1998, by and 
between Alliance Imaging, Inc., a Delaware corporation (hereinafter called 
the "Corporation"), and Raymond M. Almieri (hereinafter called the 
"Executive"). For purposes of this Agreement, employment with the Corporation 
shall include employment with any of its affiliated companies.

                                WITNESSETH THAT:

         The Corporation desires to employ the Executive as a Senior Vice 
President (a "SVP"), and the Executive desires to accept such employment;

         NOW, THEREFORE, the Corporation and the Executive, each intending to 
be legally bound, hereby mutually covenant and agree as follows:

1. EMPLOYMENT AND TERM.

         (a) Employment. The Corporation shall employ the Executive as a SVP 
of the Corporation, and the Executive shall so serve, for the term set forth 
in Paragraph 1(b).

         (b) Term. The term of the Executive's employment under this 
Agreement shall commence on the date hereof (the "Effective Time") and shall 
end on the first anniversary of the Effective Time, subject to the extension 
of such term as hereinafter provided and subject to earlier termination as 
provided in Paragraph 8. The expiration of the term of this Agreement shall 
be extended automatically by an additional three months as of the last day of 
each quarterly period following the Effective Time unless either party 
desires to modify or terminate this Agreement and notifies the other party of 
its desire to modify or terminate this Agreement at least 30 days prior to 
any such quarterly renewal date. The period of employment as provided in this 
Paragraph 1(b) is sometimes referred to herein as the "Term".

2. DUTIES.

                  During the Term, the Executive shall serve as a SVP of the 
Corporation and have all powers and duties consistent with such position. The 
Executive shall devote substantially his entire time during reasonable 
business hours (reasonable sick leave and vacations excepted) and use 
diligent efforts to fulfill faithfully, responsibly and to the best of his 
ability his duties hereunder; PROVIDED, HOWEVER, that Executive may engage in 
and devote time to other non-competitive activities to the extent that such 
time spent is immaterial and does not interfere with Executive's obligations 
hereunder. During the Term, Executive shall report to an executive of the 
Corporation. Executive's duties shall be performed, initially, principally at 
the Corporation's current offices located in Anaheim, California, or such 
other locations agreed upon by the parties. Notwithstanding, the foregoing, 
Executive may be required to travel in the conduct of the Corporation's 
business and to discharge his duties hereunder, provided that the amount 

<PAGE>

and nature of such travel is reasonably consistent with the amount and nature 
of travel engaged in by Executive during the twelve-month period immediately 
preceding the date of this Agreement.

3. SALARY.

         The Corporation shall pay to the Executive as compensation for his 
services a salary of $137,000.00 per year, payable in accordance with the 
Corporation's payroll procedures. From time to time, the Board of Directors 
of the Corporation or a committee thereof (the "Board") will review the 
Executive's performance and compensation, and will consider adjustments 
thereto.

4. ANNUAL BONUSES.

         For each calendar year during the term of employment, the Executive 
shall be eligible to receive a cash bonus based on the Corporation's 
achievement of certain operating and/or financial or other goals established 
by the Board in its sole discretion, with an initial annual target bonus 
amount (based on the Corporation's achievement of a reasonable operating 
budget to be approved by the Board) equal to 50% (the "Target Bonus") of the 
Executive's then current annual base salary. The bonus plan shall be adopted 
and administered by the Compensation Committee of the Board.

5. EQUITY INCENTIVE COMPENSATION.

         During the term of employment hereunder the Executive shall be 
eligible to participate in the Corporation's Stock Option Plan in effect as 
of the date hereof.

6. OTHER BENEFITS.

         In addition to the compensation described in Paragraphs 3 through 5, 
above, the Executive shall also be entitled to the following:

         (a) Expense Reimbursement. Executive will be reimbursed all 
reasonable, ordinary and necessary business expenses, including expenses for 
entertainment, travel and similar items that are approved by the Corporation 
in accordance with its regular policy(ies) for business expense 
reimbursement. The Corporation will reimburse Executive for all expenses upon 
a presentation by Executive of itemized accounts of such expenditures in 
accordance and in the manner and on a form reasonably prescribed by the 
Corporation.

         (b) Car Allowance. The Corporation shall pay to the Executive, on 
the first day of each month during the term of employment, a monthly 
automobile allowance (the "Automobile Allowance") of not less than $470, to 
help defray the costs associated with Executive's acquisition or maintenance 
(by lease or otherwise) of an automobile and the related insurance and 
maintenance therefor.

         (c) Vacation. The Executive shall be entitled to all legal holidays, 
and paid vacation per annum, in accordance with the Corporation's current 
policies.

                                       2

<PAGE>

         (d) Insurance and Benefits. The Executive and his "dependents," to 
the extent eligible thereunder, shall be entitled to participate in all 
employee and executive benefit plans, programs and policies currently 
available to other Corporation employees of comparable status, title and 
experience, as well as any plans, programs and policies adopted by the 
Corporation during the Term of this Agreement.

         (e) Participation in Other Benefit Plans. In addition to the 
foregoing, the Executive shall be entitled to participate in all of the other 
various retirement, welfare, fringe benefit, executive perquisite, and 
expense reimbursement plans, programs and arrangements of the Corporation to 
the same extent that employees generally of the Corporation are eligible for 
participation under the terms of such plans, programs and arrangements.

7. CONFIDENTIALITY.

         In view of the fact that Executive's work as an executive of the 
Corporation will bring Executive into close contact with many confidential 
affairs of the Corporation, including matters of a business nature, such as 
information about customers (including pricing information), costs, profits, 
markets, sales, strategic plans for future development and any other 
information not readily available to the public, Executive hereby agrees:

         (a) To keep secret all confidential matters of the Corporation 
(including without limitation such matters which the Corporation notifies 
Executive are confidential) learned prior to the date of this Agreement and 
in the course of Executive's employment hereunder, and not to disclose them 
to anyone outside of the Corporation, either during or after Executive's 
employment with the Corporation, or both, until such time as the Corporation 
gives its written consent to such disclosure;

         (b) To deliver promptly to the Corporation on termination of 
Executive's employment by the Corporation or at any other time the 
Corporation may so request, all memoranda, notes, records, reports and other 
documents (and all copies thereof) relating to the Corporation's business 
which Executive may then possess or have under Executive's control; and

         (c) That violation of this Paragraph 7 would cause the Corporation 
irreparable damage for which the Corporation cannot be reasonably compensated 
in damages in an action at law, and therefore in the event of any breach or 
threatened breach by Executive of this Paragraph 7, the Corporation shall be 
entitled to make application to a court of competent jurisdiction for 
equitable relief by way of injunction or otherwise (without being required to 
post a bond). This provision shall not, however, be construed as a waiver of 
any of the rights which the Corporation may have for damages under this 
Agreement or otherwise, and all of the Corporation's rights and remedies 
shall be unrestricted and cumulative.

         (d) For purpose of this Paragraph 7, the term Corporation shall 
include Alliance Imaging, Inc., its subsidiaries and its affiliates.

                                       3

8. TERMINATION.

         Unless earlier terminated in accordance with the following 
provisions of this Paragraph 8, the Corporation shall continue to employ the 
Executive and the Executive shall remain employed by the Corporation during 
the entire Term. Paragraph 9 hereof sets forth certain obligations of the 
Corporation in the event that the Executive's employment hereunder is 
terminated. Certain capitalized terms used in this Paragraph 8, Paragraph 9 
and Paragraph 10 hereof are defined in Paragraph 8(d), below.

         (a) Death or Disability. Except to the extent otherwise provided in 
Paragraph 9 with respect to certain post-Date of Termination payment 
obligations of the Corporation, this Agreement shall terminate immediately as 
of the Date of Termination in the event of the Executive's death or in the 
event that the Executive becomes disabled. The Executive will be deemed to be 
disabled upon the earlier of (i) the end of a six (6)-consecutive month 
period during which, by reason of physical or mental injury or disease, the 
Executive has been unable to perform substantially all of his usual and 
customary duties under this Agreement or (ii) the date that a reputable 
physician selected by the Board, and as to whom the Executive has no 
reasonable objection, determines in writing that the Executive will, by 
reason of physical or mental injury or disease, be unable to perform 
substantially all of the Executive's usual and customary duties under this 
Agreement for a period of at least six (6) consecutive months. If any 
question arises as to whether the Executive is disabled, upon reasonable 
request therefor by the Board, the Executive shall submit to reasonable 
medical examination for the purpose of determining the existence, nature and 
extent of any such disability. In accordance with Paragraph 14, the Board 
shall promptly give the Executive written notice of any such determination of 
the Executive's disability and of any decision of the Board to terminate the 
Executive's employment by reason thereof.

         (b) Discharge for Cause. In accordance with the procedures 
hereinafter set forth, the Board may discharge the Executive from his 
employment hereunder for Cause. Except to the extent otherwise provided in 
Paragraph 9 with respect to certain post-Date of Termination obligations of 
the Corporation, this Agreement shall terminate immediately as of the Date of 
Termination in the event the Executive is discharged for Cause. Any discharge 
of the Executive for Cause shall be communicated by a Notice of Termination 
to the Executive given in accordance with Paragraph 14 of this Agreement. For 
purposes of this Agreement, a "Notice of Termination" means a written notice 
which (i) indicates the specific termination provision in this Agreement 
relied upon and (ii) if the Date of Termination is to be other than the date 
of receipt of such notice, specifies the termination date (which date shall 
in all events be within fifteen (15) days after the giving of such notice). 
In the case of a discharge of the Executive for Cause, the Notice of 
Termination shall include a copy of a resolution duly adopted by the Board at 
a meeting called and held for such purpose authorizing such action. No 
purported termination of the Executive's employment for Cause shall be 
effective without a Notice of Termination.

         (c) Termination for Other Reasons. The Corporation may discharge the 
Executive without Cause by giving written notice to the Executive in 
accordance with Paragraph 14 at least thirty (30) days prior to the Date of 
Termination. The Executive may resign from 

                                       4

<PAGE>

his employment by giving written notice to the Corporation in accordance with 
Paragraph 14 at least thirty (30) days prior to the Date of Termination. 
Except to the extent otherwise provided in Paragraph 9 with respect to 
certain post-Date of Termination obligations of the Corporation, this 
Agreement shall terminate immediately as of the Date of Termination in the 
event the Executive is discharged without Cause or resigns.

         (d) Definitions. For purposes of this Agreement, the following 
capitalized terms shall have the meanings set forth below:

         (i)      "Accrued Obligations" shall mean, as of the Date of
                  Termination, the sum of (A) the Executive's base salary under
                  Paragraph 3 through the Date of Termination to the extent not
                  theretofore paid, (B) the amount of any bonus, incentive
                  compensation, deferred compensation and other cash
                  compensation accrued by the Executive as of the Date of
                  Termination to the extent not theretofore paid and (C) any
                  vacation pay, expense reimbursements and other cash
                  entitlements accrued by the Executive as of the Date of
                  Termination to the extent not theretofore paid. For the
                  purpose of this Paragraph 8(d)(i), accrued bonus shall be
                  equal to (A) the amount up to, but not to exceed, the Target
                  Bonus, based upon the Executive's regional and personal
                  performance requirements contained in the Corporation's
                  incentive compensation plan (such calculation shall be made as
                  of the last completed month preceding the Date of
                  Termination), multiplied by (B) a fraction equal to the number
                  of days in such year preceding the Date of Termination divided
                  by 365, less (C) any payments previously made with respect to
                  such Target Bonus.

         (ii)     "Cause" means that any of the following has occurred with
                  respect to Executive: (A) Executive has committed a felony
                  (other than a motor vehicle moving violation); (B) Executive
                  has stolen funds or property from the Corporation or otherwise
                  engaged in fraudulent conduct against the Corporation; (C)
                  Executive has engaged in knowing and willful misconduct which
                  is materially injurious to the Corporation; (D) Executive has
                  failed or refused to comply with the directions of the Board
                  that are reasonably consistent with Executive's current
                  executive employee title and the terms of this Agreement, the
                  failure with which to comply is materially injurious to the
                  Corporation; or (E) Executive has repeatedly failed or refused
                  to comply with the directions of the Board that are reasonably
                  consistent with Executive's current executive employee title
                  and the terms of this Agreement. Notwithstanding clause (E) of
                  the preceding sentence, no act or omission by the Executive
                  shall constitute Cause hereunder unless the Corporation has
                  given detailed written notice thereof to the Executive, and
                  the Executive has failed to remedy such act or omission within
                  a reasonable time after receiving such notice.

         (iii)    "Date of Termination" shall mean (A) in the event of a
                  discharge of the Executive by the Board for Cause, the date
                  the Executive receives a Notice of Termination, or any later
                  date specified in such Notice of Termination, 

                                       5

<PAGE>

                  as the case may be, (B) in the event of a discharge of the 
                  Executive without Cause or a resignation by the 
                  Executive, the date specified in the written notice to 
                  the Executive (in the case of discharge) or the 
                  Corporation (in the case of resignation), which date 
                  shall be no less than thirty (30) days from the date of 
                  such written notice, (C) in the event of the Executive's 
                  death, the date of the Executive's death, and (D) in the 
                  event of termination of the Executive's employment by 
                  reason of disability pursuant to Paragraph 8(a), the date 
                  the Executive receives written notice of such termination 
                  (or, if earlier, six (6) months following the date the 
                  Executive's disability began).

         (iv)     "Good Reason" shall mean any of the following:

                  (A)      the Corporation reduces Executive's base salary; or

                  (B)      the assignment to the Executive of any duties
                           inconsistent in any material respect with the
                           Executive's positions with the Corporation as set
                           forth in this Agreement (including status, offices,
                           titles and reporting requirements), authority, duties
                           or responsibilities as contemplated by Paragraph 2;
                           or

                  (C)      any material failure by the Corporation to comply
                           with any of the provisions of this Agreement, which
                           is not remedied within 15 days after notice thereof
                           from the Executive.

                  (D)      the Corporation requires Executive to change the
                           location of his principal office or offices in a
                           manner inconsistent with Paragraph 2 hereof;

                  (E)      the Corporation or the Board shall notify the
                           Executive that it does not want to renew the Term
                           pursuant to Paragraph 1(b); or

                  (F)      the Corporation otherwise subjects Executive to
                           abusive, critical or adversarial conditions such that
                           there is a material worsening of the general quality
                           of Executive's job conditions immediately prior to
                           such change.

         The following provisions describe the obligations of the Corporation to
the Executive under this Agreement upon termination of his employment.

         (a) Death, Disability, Discharge for Cause, or Resignation Without Good
Reason. In the event this Agreement terminates pursuant to Paragraph 8(a) by
reason of the death or disability of the Executive, or pursuant to Paragraph
8(b) by reason of the discharge of the Executive by the Corporation for Cause,
or pursuant to Paragraph 8(c) by reason of the resignation of the Executive
other than for Good Reason, the Corporation shall pay to the Executive, or his
heirs or estate, in the event of the Executive's death, all Accrued 

                                       6

Obligations in a lump sum in cash within thirty (30) days after the Date of 
Termination; provided further that in the event this Agreement terminates 
pursuant to Paragraph 8(a) by reason of the disability of the Executive, the 
Corporation shall continue to provide to the Executive, for a period of 
twenty-four (24) months from the commencement of such disability, all health 
benefits at least equal to those which would have been provided to Executive 
in accordance with the plans, programs and arrangements referred to in 
Paragraph 7 of this Agreement, in addition to any other benefits or payments 
to which Executive is entitled hereunder or otherwise.

         (b) Discharge Without Cause or Resignation with Good Reason. In the 
event that this Agreement terminates pursuant to Paragraph 8(c) by reason of 
the discharge of the Executive by the Corporation other than for Cause, death 
or disability or by reason of the resignation of the Executive for Good 
Reason (any such termination, a "Severance"):

         (i)      The Corporation shall pay all Accrued Obligations to the
                  Executive in a lump sum in cash within thirty (30) days after
                  the Date of Termination;

         (ii)     For a period equal to the greater of one year and the
                  remainder of the Term (assuming the Term had not expired on
                  the Date of Termination), the Corporation shall continue to
                  provide benefits to the Executive and/or the Executive's
                  dependents at least equal to those which would have been
                  provided to them in accordance with the plans, programs and
                  arrangements referred to in Paragraph 6 of this Agreement; and

         (iii)    The Corporation shall, at its sole expense (not to exceed
                  $25,000), provide the Executive with outplacement services the
                  scope and provider of which shall be selected by the
                  Executive.

10. DEFRA LIMITATION.

         (a) Notwithstanding anything in this Agreement to the contrary, in 
the event that the provisions of the Deficit Reduction Act of 1984 ("DEFRA") 
relating to "excess parachute payments" shall be applicable to any payment or 
benefit received or to be received by Executive in connection with a 
termination of the Executive's employment with the Corporation, then the 
total amount of payments or benefits payable to Executive which are deemed to 
constitute parachute payments shall be reduced to the largest amount such 
that provisions of DEFRA relating to "excess parachute payment" shall no 
longer be applicable. Should such a reduction be required, the Executive 
shall determine, in the exercise of his sole discretion, which payment or 
benefit to reduce or eliminate. Pending such determination, the Corporation 
shall continue to make all other required payments to Executive at the time 
and in the manner provided herein and shall pay the largest portion of any 
parachute payments such that the provisions of DEFRA relating to "excess 
parachute payments" shall no longer be applicable.

                                       7

<PAGE>

         (b) Recharacterization of Payments. Due to the complexity in the 
application of Section 280(G) of the Internal Revenue Code of 1986, as 
amended (the "Code") it is possible that payments made or benefits received 
hereunder should not have been made under Paragraph 10(a) (an "Overpayment"). 
In the event that it is determined in writing by the Corporation's outside 
auditors in their reasonable good faith judgment or by any court of competent 
jurisdiction that an Overpayment has been made resulting in an "Excess 
Parachute Payment" as defined in Section 280G(b)(1) of the Code, then any 
such Overpayment shall be treated for all purposes as an unsecured, long-term 
loan from the Corporation to the Executive, his personal representative, his 
successors or assigns, as the case may be, that is payable, together with 
accrued interest from the date of the making of the Overpayment at the rate 
of 8% per annum on the later to occur of the third anniversary of the payment 
of such Overpayment, or 6 months following the date upon which it is 
determined an Overpayment was made. Should it be determined that such an 
Overpayment has been made, the Executive shall determine, in the exercise of 
his sole discretion, which payments or benefits shall be deemed to constitute 
the Overpayment.

11. NO SET-OFF OR MITIGATION.

         The Corporation's obligation to make the payments provided for in 
this Agreement and otherwise to perform its obligations hereunder shall not 
be affected by any set-off, counterclaim, recoupment, defense or other claim, 
right or action which the Corporation may have against the Executive or 
others. In no event shall the Executive be obligated to seek other employment 
or take any other action by way of mitigation of the amounts payable to the 
Executive under any of the provisions of this Agreement and such amounts 
shall not be reduced whether or not the Executive obtains other employment.

12. PAYMENT OF CERTAIN EXPENSES.

         The losing party in any suit or proceeding to enforce this Agreement 
shall reimburse the prevailing party for all reasonable costs and expenses 
incurred in connection with such suit or proceeding.

13. BINDING EFFECT.

         This Agreement shall be binding upon and inure to the benefit of the 
heirs and representatives of the Executive and the successors and assigns of 
the Corporation. The Corporation shall require any successor (whether direct 
or indirect, by purchase, merger, reorganization, consolidation, acquisition 
of property or stock, liquidation, or otherwise) to all or a substantial 
portion of its assets, by agreement in form and substance reasonably 
satisfactory to the Executive, expressly to assume and agree to perform this 
Agreement in the same manner and to the same extent that the Corporation 
would be required to perform this Agreement if no such succession had taken 
place. Regardless of whether such an agreement is executed, this Agreement 
shall be binding upon any successor of the Corporation in accordance with the 
operation of law, and such successor shall be deemed the "Corporation" for 
purposes of this Agreement.

by reference as if fully stated herein. For the purpose of this Agreement, 
any amendment to said certificate of incorporation or by-laws shall not be 
effective to reduce, qualify or otherwise limit the scope, benefit or 
enforceability of this provision; provided, however, if any such amendment

required to satisfy such withholding obligations and/or (c) make other 
satisfactory arrangements with the Executive to satisfy such withholding 
obligations.

Angeles, California in accordance with the laws of the State of California.

or other charge.

19. EXECUTION IN COUNTERPARTS.

         This Agreement may be executed by the parties hereto in two (2) or 
more counterparts, each of which shall be deemed to be an original, but all 
such counterparts shall constitute one and the same instrument, and all

21. SEVERABILITY.

         If any provision of this Agreement shall be adjudged by any court of

judgment shall not affect, impair or invalidate the remainder of this 
Agreement. Furthermore, if the scope of any restriction or requirement

requirement shall be enforced to the maximum extent permitted by law, and the

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT is made and entered into as of April 29, 1998, by and 
between Alliance Imaging, Inc., a Delaware corporation (hereinafter called 
the "Corporation"), and Russell D. Phillips, Jr. (hereinafter called the 
"Executive").

                                WITNESSETH THAT:

         The Corporation desires to employ the Executive as its General 
Counsel ("GC"), and the Executive desires to accept such employment;

         NOW, THEREFORE, the Corporation and the Executive, each intending to 
be legally bound, hereby mutually covenant and agree as follows:

1.       EMPLOYMENT AND TERM.

         (a) Employment. The Corporation shall employ the Executive as the GC 
of the Corporation, and the Executive shall so serve, for the term set forth 
in Paragraph 1(b).

         (b) Term. The term of the Executive's employment under this 
Agreement shall commence on the date hereof (the "Effective Time") and shall 
end on the second anniversary of the Effective Time, subject to the extension 
of such term as hereinafter provided and subject to earlier termination as 
provided in Paragraph 8. The expiration of the term of this Agreement shall 
be extended automatically by an additional three months as of the last day of 
each quarterly period following the Effective Time unless either party 
desires to modify or terminate this Agreement and notifies the other party of 
its desire to modify or terminate this Agreement at least 30 days prior to 
any such quarterly renewal date. The period of employment as provided in this 
Paragraph 1(b) is sometimes referred to herein as the "Term".

2.       DUTIES.

         During the Term, the Executive shall serve as GC of the Corporation 
and have all powers and duties consistent with such position. The Executive 
shall devote substantially his entire time during reasonable business hours 
(reasonable sick leave and vacations excepted) and use diligent efforts to 
fulfill faithfully, responsibly and to the best of his ability his duties 
hereunder; PROVIDED, HOWEVER, that Executive may engage in and devote time to 
other non-competitive activities to the extent that such time spent is 
immaterial and does not interfere with Executive's obligations hereunder. 
During the Term, Executive shall report to the Chairman and Chief Executive 
Officer of the Corporation. Executive's duties shall be performed, initially, 
principally at the Corporation's current offices located in Anaheim, 
California, unless Executive otherwise agrees in writing. Notwithstanding, 
the foregoing, Executive may be required to travel in the conduct of the 
Corporation's business and to discharge his duties hereunder, provided that 
the amount and nature of such travel is reasonably consistent with the amount 
and 

<PAGE>

nature of travel engaged in by other senior executives of the Corporation 
during the twelve-month period immediately preceding the date of this 
Agreement.

3.       SALARY.

         The Corporation shall pay to the Executive as compensation for his 
services a salary of $125,000 per year, payable in accordance with the 
Corporation's payroll procedures. From time to time, the Board of Directors 
of the Corporation or a committee thereof (the "Board") will review the 
Executive's performance and compensation, and will consider adjustments 
thereto.

4.       ANNUAL BONUSES.

         For each calendar year during the term of employment, the Executive 
shall be eligible to receive a cash bonus based on the Corporation's 
achievement of certain operating and/or financial or other goals established 
by the Board in its sole discretion, with an annual target bonus amount 
(based on the Corporation's achievement of a reasonable operating budget to 
be approved by the Board) equal to 30% (the "Target Bonus") of the 
Executive's then current annual base salary. The bonus plan shall be adopted 
and administered by the Compensation Committee of the Board.

5.       EQUITY INCENTIVE COMPENSATION.

         During the term of employment hereunder the Executive shall be 
eligible to participate in the Corporation's Stock Option Plan in effect as 
of the date hereof.

6.       OTHER BENEFITS.

         In addition to the compensation described in Paragraphs 3 through 5, 
above, the Executive shall also be entitled to the following:

         (a) Expense Reimbursement. Executive will be reimbursed all 
reasonable, ordinary and necessary business expenses, including expenses for 
entertainment, travel and similar items that are approved by the Corporation 
in accordance with its regular policy(ies) for business expense 
reimbursement. The Corporation will reimburse Executive for all expenses upon 
a presentation by Executive of itemized accounts of such expenditures in 
accordance and in the manner and on a form reasonably prescribed by the 
Corporation.

         (b) Car Allowance. The Corporation shall pay to the Executive, on 
the first day of each month during the term of employment, a monthly 
automobile allowance (the "Automobile Allowance") of not less than $400, to 
help defray the costs associated with Executive's acquisition or maintenance 
(by lease or otherwise) of an automobile and the related insurance and 
maintenance therefor.

         (c) Vacation. The Executive shall be entitled to all legal holidays, 
and three weeks paid vacation per annum, in accordance with the Corporation's 
policies.

                                       2

<PAGE>

         (d) Insurance and Benefits. The Executive and his "dependents," to 
the extent eligible thereunder, shall be entitled to participate in all 
employee and executive benefit plans, programs and policies currently 
available to other Corporation employees of comparable status, title and 
experience, as well as any plans, programs and policies adopted by the 
Corporation during the Term of this Agreement.

         (e) Participation in Other Benefit Plans. In addition to the 
foregoing, the Executive shall be entitled to participate in all of the other 
various retirement, welfare, fringe benefit, executive perquisite, and 
expense reimbursement plans, programs and arrangements of the Corporation to 
the same extent that employees generally of the Corporation are eligible for 
participation under the terms of such plans, programs and arrangements.

7.       CONFIDENTIALITY.

         In view of the fact that Executive's work as an executive of the 
Corporation will bring Executive into close contact with many confidential 
affairs of the Corporation, including matters of a business nature, such as 
information about customers (including pricing information), costs, profits, 
markets, sales, strategic plans for future development and any other 
information not readily available to the public, Executive hereby agrees:

         (a) To keep secret all confidential matters of the Corporation 
(including without limitation such matters which the Corporation notifies 
Executive are confidential) learned prior to the date of this Agreement and 
in the course of Executive's employment hereunder, and not to disclose them 
to anyone outside of the Corporation, either during or after Executive's 
employment with the Corporation, or both, until such time as the Corporation 
gives its written consent to such disclosure;

         (b) To deliver promptly to the Corporation on termination of 
Executive's employment by the Corporation or at any other time the 
Corporation may so request, all memoranda, notes, records, reports and other 
documents (and all copies thereof) relating to the Corporation's business 
which Executive may then possess or have under Executive's control; and

         (c) That violation of this Paragraph 7 would cause the Corporation 
irreparable damage for which the Corporation cannot be reasonably compensated 
in damages in an action at law, and therefore in the event of any breach or 
threatened breach by Executive of this Paragraph 7, the Corporation shall be 
entitled to make application to a court of competent jurisdiction for 
equitable relief by way of injunction or otherwise (without being required to 
post a bond). This provision shall not, however, be construed as a waiver of 
any of the rights which the Corporation may have for damages under this 
Agreement or otherwise, and all of the Corporation's rights and remedies 
shall be unrestricted and cumulative.

                                       3

<PAGE>

8.       TERMINATION.

         Unless earlier terminated in accordance with the following 
provisions of this Paragraph 8, the Corporation shall continue to employ the 
Executive and the Executive shall remain employed by the Corporation during 
the entire Term. Paragraph 9 hereof sets forth certain obligations of the 
Corporation in the event that the Executive's employment hereunder is 
terminated. Certain capitalized terms used in this Paragraph 8, Paragraph 9 
and Paragraph 10 hereof are defined in Paragraph 8(d), below.

         (a) Death or Disability. Except to the extent otherwise provided in 
Paragraph 9 with respect to certain post-Date of Termination payment 
obligations of the Corporation, this Agreement shall terminate immediately as 
of the Date of Termination in the event of the Executive's death or in the 
event that the Executive becomes disabled. The Executive will be deemed to be 
disabled upon the earlier of (i) the end of a six (6)-consecutive month 
period during which, by reason of physical or mental injury or disease, the 
Executive has been unable to perform substantially all of his usual and 
customary duties under this Agreement or (ii) the date that a reputable 
physician selected by the Board, and as to whom the Executive has no 
reasonable objection, determines in writing that the Executive will, by 
reason of physical or mental injury or disease, be unable to perform 
substantially all of the Executive's usual and customary duties under this 
Agreement for a period of at least six (6) consecutive months. If any 
question arises as to whether the Executive is disabled, upon reasonable 
request therefor by the Board, the Executive shall submit to reasonable 
medical examination for the purpose of determining the existence, nature and 
extent of any such disability. In accordance with Paragraph 14, the Board 
shall promptly give the Executive written notice of any such determination of 
the Executive's disability and of any decision of the Board to terminate the 
Executive's employment by reason thereof.

         (b) Discharge for Cause. In accordance with the procedures 
hereinafter set forth, the Board may discharge the Executive from his 
employment hereunder for Cause. Except to the extent otherwise provided in 
Paragraph 9 with respect to certain post-Date of Termination obligations of 
the Corporation, this Agreement shall terminate immediately as of the Date of 
Termination in the event the Executive is discharged for Cause. Any discharge 
of the Executive for Cause shall be communicated by a Notice of Termination 
to the Executive given in accordance with Paragraph 14 of this Agreement. For 
purposes of this Agreement, a "Notice of Termination" means a written notice 
which (i) indicates the specific termination provision in this Agreement 
relied upon and (ii) if the Date of Termination is to be other than the date 
of receipt of such notice, specifies the termination date (which date shall 
in all events be within fifteen (15) days after the giving of such notice). 
In the case of a discharge of the Executive for Cause, the Notice of 
Termination shall include a copy of a resolution duly adopted by the Board at 
a meeting called and held for such purpose authorizing such action. No 
purported termination of the Executive's employment for Cause shall be 
effective without a Notice of Termination.

Executive without Cause by giving written notice to the Executive in 
accordance with Paragraph 14 at least thirty (30) days prior to the Date of 
Termination. The Executive may resign from

his employment by giving written notice to the Corporation in accordance with 
Paragraph 14 at least thirty (30) days prior to the Date of Termination. 
Except to the extent otherwise provided in Paragraph 9 with respect to 
certain post-Date of Termination obligations of the Corporation, this 
Agreement shall terminate immediately as of the Date of Termination in the 
event the Executive is discharged without Cause or resigns.

         (d) Definitions. For purposes of this Agreement, the following 
capitalized terms shall have the meanings set forth below:

                  compensation, deferred compensation and other cash

                  vacation pay, expense reimbursements and other cash
                  entitlements accrued by the Executive as of the Date of
                  Termination to the extent not theretofore paid. For the
                  purpose of this Paragraph 8(d)(i), the amount of bonus accrued
                  shall be equal to (A) the Average Bonus, multiplied by (B) a
                  fraction equal to the number of days in such year preceding
                  the Date of Termination divided by 365.

         (ii)     "Average Bonus" means (A) if a termination of employment of

                  in which such termination occurs and (B) if a termination of
                  employment of the Executive occurs on or after January 1,
                  1999, the actual cash bonus earned by the Executive pursuant
                  to Section 4 for the calendar year completed immediately prior
                  to the time in question.

         (iii)    "Cause" means that any of the following has occurred with
                  respect to Executive: (A) Executive has committed a felony
                  (other than a motor vehicle moving violation); (B) Executive
                  has stolen funds or property from the Corporation or otherwise
                  engaged in fraudulent conduct against the Corporation; (C)
                  Executive has engaged in knowing and willful misconduct which
                  is materially injurious to the Corporation; (D) Executive has
                  failed or refused to comply with the directions of the Board
                  that are reasonably consistent with Executive's current
                  executive employee title and the terms of this Agreement, the
                  failure with which to comply is materially injurious to the
                  Corporation; or (E) Executive has repeatedly failed or refused
                  to comply with the directions of the Board that are reasonably
                  consistent with Executive's current executive employee title
                  and the terms of this Agreement. Notwithstanding clause (E) of
                  the preceding sentence, no act or omission by the Executive
                  shall constitute Cause hereunder unless the Corporation has
                  given detailed written notice thereof to the Executive, and
                  the Executive has failed to remedy such act or omission within
                  a reasonable time after receiving such notice.

                  discharge of the Executive by the Board for Cause, the date
                  the Executive receives a Notice of Termination, or any later
                  date specified in such Notice of Termination, as the case may
                  be, (B) in the event of a discharge of the Executive without
                  Cause or a resignation by the Executive, the date specified in
                  the written notice to the Executive (in the case of discharge)
                  or the Corporation (in the case of resignation), which date

                  receives written notice of such termination (or, if earlier,
                  six (6) months following the date the Executive's disability
                  began).

         (v)      "Good Reason" shall mean any of the following:

                  (A)      the Corporation reduces Executive's base salary; or

                  (B)      the assignment to the Executive of any duties
                           inconsistent in any material respect with the
                           Executive's positions with the Corporation as set
                           forth in this Agreement (including status, offices,
                           titles and reporting requirements), authority, duties
                           or responsibilities as contemplated by Paragraph 2;
                           or

                  (C)      any material failure by the Corporation to comply
                           with any of the provisions of this Agreement, which
                           is not remedied within 15 days after notice thereof
                           from the Executive.

                  (D)      the Corporation requires Executive to change the
                           location of his principal office or offices in a
                           manner inconsistent with Paragraph 2 hereof;

                  (E)      the Corporation or the Board shall notify the

                           pursuant to Paragraph 1(b); or

                  (F)      the Corporation otherwise subjects Executive to

                           of Executive's job conditions immediately prior to
                           such change.

9.       OBLIGATIONS OF THE CORPORATION UPON TERMINATION.

         The following provisions describe the obligations of the Corporation to
the Executive under this Agreement upon termination of his employment.

         (a) Death, Disability, Discharge for Cause, or Resignation Without Good
Reason. In the event this Agreement terminates pursuant to Paragraph 8(a) by
reason of the death or disability of the Executive, or pursuant to Paragraph
8(b) by reason of the discharge of 

                                       6

<PAGE>

the Executive by the Corporation for Cause, or pursuant to Paragraph 8(c) by 
reason of the resignation of the Executive other than for Good Reason, the 
Corporation shall pay to the Executive, or his heirs or estate, in the event 
of the Executive's death, all Accrued Obligations in a lump sum in cash 
within thirty (30) days after the Date of Termination; provided further that 
in the event this Agreement terminates pursuant to Paragraph 8(a) by reason 
of the disability of the Executive, the Corporation shall continue to provide 
to the Executive, for a period of twenty-four (24) months from the 
commencement of such disability, all health benefits at least equal to those 
which would have been provided to Executive in accordance with the plans, 
programs and arrangements referred to in Paragraph 7 of this Agreement, in 
addition to any other benefits or payments to which Executive is entitled 
hereunder or otherwise.

         (b) Discharge Without Cause or Resignation with Good Reason. In the 
event that this Agreement terminates pursuant to Paragraph 8(c) by reason of 
the discharge of the Executive by the Corporation other than for Cause, death 
or disability or by reason of the resignation of the Executive for Good 
Reason (any such termination, a "Severance"):

         (i)      The Corporation shall pay all Accrued Obligations to the
                  Executive in a lump sum in cash within thirty (30) days after
                  the Date of Termination;

         (ii)     For a period equal to the greater of two years and the
                  remainder of the Term (assuming the Term had not expired on
                  the Date of Termination), the Corporation shall continue to
                  provide benefits to the Executive and/or the Executive's
                  family at least equal to those which would have been provided
                  to them in accordance with the plans, programs and
                  arrangements referred to in Paragraph 6 of this Agreement; and

         (iii)    The Corporation shall, at its sole expense (not to exceed
                  $25,000), provide the Executive with outplacement services the
                  scope and provider of which shall be selected by the
                  Executive.

10. DEFRA LIMITATION.

         (a) Notwithstanding anything in this Agreement to the contrary, in 
the event that the provisions of the Deficit Reduction Act of 1984 ("DEFRA") 
relating to "excess parachute payments" shall be applicable to any payment or 
benefit received or to be received by Executive in connection with a 
termination of the Executive's employment with the Corporation, then the 
total amount of payments or benefits payable to Executive which are deemed to 
constitute parachute payments shall be reduced to the largest amount such 
that provisions of DEFRA relating to "excess parachute payment" shall no 
longer be applicable. Should such a reduction be required, the Executive 
shall determine, in the exercise of his sole discretion, which payment or 
benefit to reduce or eliminate. Pending such determination, the Corporation 
shall continue to make all other required payments to Executive at the time 
and in the manner provided herein and shall pay the largest portion 

                                       7

<PAGE>

of any parachute payments such that the provisions of DEFRA relating to 
"excess parachute payments" shall no longer be applicable.

         (b) Recharacterization of Payments. Due to the complexity in the 
application of Section 280(G) of the Internal Revenue Code of 1986, as 
amended (the "Code") it is possible that payments made or benefits received 
hereunder should not have been made under Paragraph 10(a) (an "Overpayment"). 
In the event that it is determined in writing by the Corporation's outside 
auditors in their reasonable good faith judgment or by any court of competent 
jurisdiction that an Overpayment has been made resulting in an "Excess 
Parachute Payment" as defined in Section 280G(b)(1) of the Code, then any 
such Overpayment shall be treated for all purposes as an unsecured, long-term 
loan from the Corporation to the Executive, his personal representative, his 
successors or assigns, as the case may be, that is payable, together with 
accrued interest from the date of the making of the Overpayment at the rate 
of 8% per annum on the later to occur of the third anniversary of the payment 
of such Overpayment, or 6 months following the date upon which it is 
determined an Overpayment was made. Should it be determined that such an 
Overpayment has been made, the Executive shall determine, in the exercise of 
his sole discretion, which payments or benefits shall be deemed to constitute 
the Overpayment.

11.      NO SET-OFF OR MITIGATION.

         The Corporation's obligation to make the payments provided for in 
this Agreement and otherwise to perform its obligations hereunder shall not 
be affected by any set-off, counterclaim, recoupment, defense or other claim, 
right or action which the Corporation may have against the Executive or 
others. In no event shall the Executive be obligated to seek other employment 
or take any other action by way of mitigation of the amounts payable to the 
Executive under any of the provisions of this Agreement and such amounts 
shall not be reduced whether or not the Executive obtains other employment.

12.      PAYMENT OF CERTAIN EXPENSES.

         The losing party in any suit or proceeding to enforce this Agreement 
shall reimburse the prevailing party for all reasonable costs and expenses 
incurred in connection with such suit or proceeding.

13.      BINDING EFFECT.

         This Agreement shall be binding upon and inure to the benefit of the 
heirs and representatives of the Executive and the successors and assigns of 
the Corporation. The Corporation shall require any successor (whether direct 
or indirect, by purchase, merger, reorganization, consolidation, acquisition 
of property or stock, liquidation, or otherwise) to all or a substantial 
portion of its assets, by agreement in form and substance reasonably 
satisfactory to the Executive, expressly to assume and agree to perform this 
Agreement in the same manner and to the same extent that the Corporation 
would be required to perform this Agreement if no such succession had taken 
place. Regardless of whether such an agreement is executed, this Agreement 
shall be binding upon any 

                                       8

<PAGE>

successor of the Corporation in accordance with the operation of law, and 
such successor shall be deemed the "Corporation" for purposes of this 
Agreement.

extent permitted by law for his services to, or on behalf of the Corporation,

other capacity in which he may serve the Corporation or its interests. In 
furtherance of such agreement to indemnify, but not by way of limitation, the 
terms of the Corporation's certificate of incorporation and by-laws providing 
for such indemnification and payment of expenses, as in effect on the date 
hereof (and, which are attached hereto as Exhibit A), are hereby incorporated 
by reference as if fully stated herein. For the purpose of this Agreement, 
any amendment to said certificate of incorporation or by-laws shall not be 
effective to reduce, qualify or 

                                       9

<PAGE>

otherwise limit the scope, benefit or enforceability of this provision; 
provided, however, if any such amendment extends or improves the scope, 
benefit or enforceability of the indemnification and payment of expenses 
contained in such certificate of incorporation or by-laws for any officer, 
director, employee or agent, such extended or improved provisions shall be 
deemed to be incorporated by reference herein for the benefit of the 
Executive without any further action by the Corporation or the Executive.

16.      TAX WITHHOLDING.

         The Corporation shall provide for the withholding of any taxes 
required to be withheld by federal, state, or local law with respect to any 
payment in cash, shares of stock and/or other property made by or on behalf 
of the Corporation to or for the benefit of the Executive under this 
Agreement or otherwise. The Corporation may, at its option: (a) withhold such 
taxes from any cash payments owing from the Corporation to the Executive, (b) 
require the Executive to pay to the Corporation in cash such amount as may be 
required to satisfy such withholding obligations and/or (c) make other 
satisfactory arrangements with the Executive to satisfy such withholding 
obligations.

17.      ARBITRATION.

         Except as to any controversy or claim which the Executive elects, by 
written notice to the Corporation, to have adjudicated by a court of 
competent jurisdiction, any controversy or claim arising out of or relating 
to this Agreement or the breach hereof shall be settled by arbitration in Los 
Angeles, California in accordance with the laws of the State of California. 
The arbitration shall be conducted in accordance with the rules of the 
American Arbitration Association. The costs and expenses of the arbitrator(s) 
shall be borne by the Corporation. The award of the arbitrator(s) shall be 
binding upon the parties. Judgment upon the award rendered by the 
arbitrator(s) may be entered in any court having jurisdiction.

18.      NO ASSIGNMENT.

         Except as otherwise expressly provided herein, this Agreement is not 
assignable by any party and no payment to be made hereunder shall be subject 
to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance 
or other charge.

19.      EXECUTION IN COUNTERPARTS.

         This Agreement may be executed by the parties hereto in two (2) or 
more counterparts, each of which shall be deemed to be an original, but all 
such counterparts shall constitute one and the same instrument, and all 
signatures need not appear on any one counterpart.

20.      JURISDICTION AND GOVERNING LAW.

         Except as provided in Paragraph 17, jurisdiction over disputes with 
regard to this Agreement shall be exclusively in the courts of the State of 
California, and this Agreement shall be construed and interpreted in 
accordance with and governed by the laws of the State of California, other 
than the conflict of laws provisions of such laws.

21.      SEVERABILITY.

         If any provision of this Agreement shall be adjudged by any court of 
competent jurisdiction to be invalid or unenforceable for any reason, such 
judgment shall not affect, impair or invalidate the remainder of this 
Agreement. Furthermore, if the scope of any restriction or requirement 
contained in this Agreement is too broad to permit enforcement of such 
restriction or requirement to its full extent, then such restriction or 
requirement shall be enforced to the maximum extent permitted by law, and the 
Executive consents and agrees that any court of competent jurisdiction may so 
modify such scope in any proceeding brought to enforce such restriction or 
requirement.

22.      PRIOR UNDERSTANDINGS.

         This Agreement embodies the entire understanding of the parties

                                    AGREEMENT

Russell:

         1. Reference is made to (i) the Alliance Imaging, Inc. 1997 Stock 
Option Plan (the "Option Plan") and (ii) the Stock Option Agreement (the 
"Option Agreement") between Alliance Imaging, Inc. (the "Company") and you, 
dated as of April 28, 1998. In consideration of the Company granting you 
options under the Option Plan, executing and delivering the Option Agreement 
and making the payments described in Paragraph 5 below, you agree that no 
Competition Event (as defined below) shall occur prior to two years after the 
Date of Termination (as defined in the employment agreement between the 
Company and you as of the date hereof (the "Employment Agreement")). Defined 
terms used but not defined herein shall have the meaning ascribed thereto in 
the Employment Agreement.

         2. For purposes of this letter agreement, a Competition Event shall 
occur if you directly or indirectly (i) engage in any imaging business or any 
other business that becomes material to the Company's business during your 
employment by the Company (the "Company Business") within the United States; 
(ii) compete or participate as agent, employee, consultant, advisor, 
representative or otherwise in any enterprise engaged in a business which has 
any operations engaged in the Company Business within the United States; or 
(iii) compete or participate as a stockholder, partner or joint venturer, or 
have any direct or indirect financial interest, in any enterprise which has 
any material operations engaged in the Company Business within the United 
States; PROVIDED, HOWEVER, that nothing contained herein shall prohibit you 
from (A) owning, operating or managing any business, or acting upon any 
business opportunity, after obtaining approval of a majority of the Board of 
Directors of the Company and a majority of the independent members of the 
Board of Directors of the Company (if any); or (B) owning no more than five 
percent (5%) of the equity of any publicly traded entity with respect to 
which you do not serve as an officer, director, employee, consultant or in 
any other capacity other than as an investor.

         3. As a means reasonably designed to protect certain confidential 
information of the Company which would otherwise inherently be utilized in 
the following proscribed activities, and in partial consideration of the 
Company's covenant to make the payments described in Paragraph 5, you agree 
that you will not, prior to the date you cease to receive payments under 
Paragraph 5 below, solicit or make any other contact with, directly or 
indirectly, any customer of the Company as of the Date of Termination with 
respect to the provision of any service to any such customer that is the same 
or substantially similar to any service provided to such customer by the 
Company.

         4. In partial consideration of the Company's covenant to make the 
payments described in Paragraph 5, you agree that you will not, prior to the 
date you cease to receive payments under paragraph 5, solicit or make any 
other contact with, directly or indirectly, any employee of the Company on 
the Date of Termination (or any person who was employed by the Company at any 
time during the three-month period prior to the Date of Termination) with 
respect to any employment, services or other business relationship.

         5. In partial consideration of your covenants contained herein, the 
Company shall, immediately following the Date of Termination, pay you an 
amount equal to (A) the sum of your base salary as of the Date of Termination 
and your Average Bonus, multiplied by (B) a fraction, the numerator of which 
is the greater of 730 and the number of days remaining in the Term as of the 
Date of Termination assuming the Term had not expired on the Date of 
Termination and the denominator of which is 365. All payments under this 
Paragraph 5 shall be made in equal installments on a bi-weekly basis over a 
period equal to the greater of the remaining Term (assuming the Term had not 
expired) or two years. Notwithstanding the foregoing, the Company shall not 
be obligated to make any payments under this Paragraph 5 to you if you (x) 
fail to cure a breach of this Agreement within fifteen days after receipt of 
notice of such breach from the Company, or (y) if your employment with the 
Company is terminated by reason of your death or disability or for Cause or 
by reason of your resignation other than for Good Reason.

         6. Notwithstanding paragraph 1 through 4 hereof, if the Company 
shall fail to make any payment to you that the Company is obligated to make 
pursuant to Paragraph 5 and such failure shall continue for more than five 
days after receipt of notice from you, all future payments to you under 
Paragraph 5 shall become immediately due and payable or you shall be relieved 
of all obligations under this Agreement.

         You acknowledge that irreparable damage would occur in the event of 
a breach of the provisions of this Agreement by you. It is accordingly agreed 
that, in addition to any other remedy to which it is entitled at law or in 
equity, the Company shall be entitled to an injunction or injunctions to 
prevent breaches of this letter agreement and to enforce specifically the 
terms and provisions of this letter agreement.

         7. If, at the time of enforcement, any sentence, paragraph, clause, 
or combination of the same of this Agreement is in violation of the law of 
any state where applicable, such sentence, paragraph, clause, or combination 
of the same shall be void in the

jurisdictions where it is unlawful, and the remainder of this Agreement shall 
remain binding on the parties. In the event that any part of any covenant of 
this Agreement is determined by a court of law to be overly broad thereby 
making the covenant unenforceable, the parties agree that such court shall 
substitute a judicially enforceable limitation in its place, and that as so 
modified, the covenants shall be binding upon the parties as if originally 
set forth in this Agreement.

         If you are in agreement with the foregoing, please sign a copy of 
this letter where indicated below.


                                       Very truly yours,

                                       Alliance Imaging, Inc.
