                                  ----------
   
  Alliance Imaging, Inc. ("Alliance" or the "Company") is offering (the
"Offering") $125,000,000 aggregate principal amount of its    % Senior
Subordinated Notes due 2005 (the "Fixed Rate Notes") and $40,000,000 aggregate
principal amount of its Senior Subordinated Floating Rate Notes due 2005 (the
"Floating Rate Notes" and, together with the Fixed Rate Notes, the "Notes").
The Offering is part of the financing that will be used to consummate the
recapitalization of Alliance (the "Recapitalization"). The Recapitalization
will be effected pursuant to an Agreement and Plan of Merger (the
"Recapitalization Merger Agreement"). Under the terms of the Recapitalization
Merger Agreement, an entity formed by affiliates of Apollo Management, L.P.
(collectively, "Apollo") will merge with and into Alliance upon the completion
of the Offering, with Alliance as the surviving corporation. The consummation
of the Offering, the Recapitalization and the transactions contemplated thereby
will be concurrent, and the Offering is conditioned upon the other Transactions
(as defined).     
   
  Interest on the Notes will be payable semi-annually on each and , commencing
, 1998, at the rate of    % per annum in the case of the Fixed Rate Notes, and
at a rate per annum equal to LIBOR (as defined) plus   % in the case of the
Floating Rate Notes. Interest on the Floating Rate Notes will be reset semi-
annually. The Fixed Rate Notes will be redeemable, in whole or in part, at the
option of the Company, on or after , 2001, and the Floating Rate Notes will be
redeemable, in whole or in part, at the option of the Company, at any time, in
each case at the redemption prices set forth herein plus accrued interest to
the date of redemption. In addition, on or prior to , 2000, the Company may, at
its option, redeem up to 40% of the aggregate principal amount of the Fixed
Rate Notes with the net cash proceeds of one or more Equity Offerings (as
defined), at the redemption price set forth herein plus accrued interest to the
date of redemption; provided, however, that after any such redemption, 60% of
the aggregate principal amount of the Fixed Rate Notes issued must remain
outstanding.     
 
  The Notes will be general unsecured obligations of the Company and will be
subordinated in right of payment to all Senior Debt (as defined) of the
Company, including indebtedness under the Credit Agreement (as defined). The
Notes will be unconditionally guaranteed (the "Guarantees") on a senior
subordinated basis by substantially all of Alliance's domestic subsidiaries
(the "Guarantors"). The Guarantees will be general unsecured obligations of the
Guarantors and will be subordinated in right of payment to all Guarantor Senior
Debt (as defined) of the Guarantors. As of September 30, 1997, after giving pro
forma effect to the Transactions, the Company would have had approximately
$56.9 million of Senior Debt outstanding (excluding unused commitments of $75.0
million under the Credit Agreement).
   
  Upon a Change of Control (as defined), each holder of the Notes will have the
right to require the Company to repurchase such holder's Notes at a price equal
to 101% of their principal amount plus accrued interest to the date of
repurchase. There can be no assurance that the Company will have the financial
ability or will be permitted by the Credit Agreement to repurchase the Notes.
See "Risk Factors--Repurchase of Notes upon a Change of Control." In addition,
the Company will be obligated to offer to repurchase the Notes at 100% of their
principal amount plus accrued interest to the date of repurchase in the event
of certain asset sales.     
 
  There is no existing market for the Notes, and there can be no assurance as
to the liquidity of any markets that may develop for the Notes, the ability of
the holders of the Notes to sell their Notes or the price at which such holders
would be able to sell their Notes. The Company does not intend to apply for
listing of the Notes on any securities exchange. See "Risk Factors--Absence of
Public Market."
 
  SEE "RISK FACTORS" BEGINNING ON PAGE 10 FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED IN EVALUATING AN INVESTMENT IN THE NOTES.
 
THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES AND
EXCHANGE  COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS  THE SECURITIES
 AND EXCHANGE  COMMISSION OR ANY  STATE SECURITIES COMMISSION  PASSED UPON THE
 ACCURACY OR  ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION  TO THE CONTRARY
  IS A CRIMINAL OFFENSE.

                                  THE COMPANY
 
  The Company is a leading nationwide provider of diagnostic imaging services
and the largest operator of state-of-the-art mobile diagnostic imaging systems
and related outsourced radiology services in the United States. The Company
primarily provides magnetic resonance imaging ("MRI") systems and services to
hospitals and other health care providers on a mobile, shared user basis. The
Company also provides dedicated, full-time MRI systems and services as well as
full-service management of imaging operations for selected hospitals. The
Company's services enable small to mid-size hospitals to gain access to
advanced diagnostic imaging technology and related value-added services without
making a substantial investment in equipment and personnel. The Company
operates a fleet of 98 MRI systems and services 356 MRI customers in 36 states
under exclusive contracts with an average remaining length of approximately 24
months as of September 30, 1997.
 
  Since the beginning of 1995, Alliance has substantially increased revenues by
adding new customers and increasing scan volumes at existing customer sites.
During the same period, the growth rate of Alliance's EBITDA (as defined
herein) and net income has exceeded the growth rate of revenues principally as
a result of spreading costs (which are primarily fixed) over a larger revenue
base and implementing cost reduction and containment measures.
 
                               INDUSTRY OVERVIEW
 
  The diagnostic imaging industry, which involves the use of non-surgical
techniques to generate representations of internal structures and organs on
film or video, generates annual revenues in excess of $50 billion in the United
States, or 5% to 6% of total health care spending. MRI services, which involve
the use of high strength magnetic fields to produce cross-sectional images of
the anatomy, constituted approximately $6 to $7 billion of the diagnostic
imaging industry in 1996. The approximately 4,000 MRI systems in the United
States include approximately 2,400 hospital owned systems, 1,000 independent
fixed site systems and 600 mobile systems.
 
  MRI facilitates the early diagnosis of diseases and disorders, often
minimizing the cost and amount of care needed and frequently eliminating the
need for invasive diagnostic procedures. MRI is the preferred imaging modality
for the brain, the spine and soft tissue because it produces a superior image
and does not expose patients to ionizing radiation. As a result of the cost
efficiency and clinical effectiveness of MRI, hospitals and other health care
providers are facing competitive pressures to provide MRI technology and
related services despite budgetary limitations. Increasingly, such providers
are utilizing third parties such as the Company to provide the necessary
imaging systems and related services to avoid substantial equipment and
operating costs. Mobile MRI operators employ systems housed in specially
designed trailers and typically enter into long-term contracts to provide a
specified schedule of service on a fee-per-scan basis. Operators then design
schedules for each system to rotate among multiple hospitals in a manner that
optimizes system utilization.
 
                                       1
<PAGE>
 
 
  The MRI services industry has experienced substantial growth in demand as
measured by total scan volumes, which have increased from 5.4 million in 1990
to 8.8 million in 1996. According to an industry consultant, scan volumes are
projected to grow at approximately 7% to 8% per year through 1999 and at 5% per
year thereafter. Growth in the MRI industry is attributable to increased
physician acceptance, substitution of MRI for other imaging modalities
(including x-ray based techniques), expanding applications for MRI technology
and health care reform which encourages outpatient services.
 
  The MRI services industry is highly fragmented. Recently, however, the
industry has begun to undergo consolidation. The Company believes such
consolidation is primarily the result of (i) economies of scale in the
provision of services to a larger customer base; (ii) cost-effective purchasing
of equipment, supplies and services by larger companies; and (iii) the decision
by many smaller, capital constrained operators to sell their MRI businesses
rather than make substantial investments in new imaging systems. Despite the
recent trend, management estimates that as of September 30, 1997, the top eight
MRI service providers operated only 13% of total MRI systems in the United
States.
 
                             COMPETITIVE STRENGTHS
 
  The Company attributes its market leadership and its significant
opportunities for continued growth and increased profitability to the following
strengths:
 
  Largest Provider of Mobile MRI Services. The Company operates 98 MRI systems
in 36 states. The Company believes that the next largest mobile operator has a
fleet of approximately 70 MRI systems. Compared to its smaller competitors, the
Company believes it benefits from (i) significant equipment purchasing savings;
(ii) attractive service and maintenance contracts from its primary equipment
suppliers; (iii) strong name recognition and a reputation for quality service;
(iv) substantial financial flexibility and access to lower-cost capital; and
(v) the ability to efficiently deploy systems in a manner which maximizes fleet
utilization while satisfying customer requirements.
 
  Technologically Advanced MRI Fleet. The Company has invested approximately
$78 million since January 1, 1995 to replace and upgrade existing systems and
to purchase new systems. As a result, the Company believes that it has upgraded
substantially all of its systems and expects most of its capital expenditures
for at least the next three to five years to relate to new system purchases. Of
the Company's 98 MRI systems, 73 are state-of-the-art, high-field 1.0 or 1.5
Tesla systems and 13 are state-of-the-art, mid-field 0.5 Tesla systems. The
Company believes its fleet is among the newest and most advanced in the
industry, enabling the Company to perform a wider variety and greater volume of
scans and produce higher quality images, which the Company believes provides a
significant competitive advantage. Moreover, all of the Company's state-of-the-
art systems are designed to facilitate hardware and software upgrades. As a
result, the Company's systems should remain on the leading edge of
technological developments. In addition, while many of its competitors lease
their systems, the Company owns the vast majority of its systems, generally
providing greater flexibility and lower costs over the life of the systems.
 
  Exclusive, Long-Term Contracts in Attractive Markets. The Company generates
substantially all of its revenues from exclusive, long-term contracts with
hospitals and other health care providers, with the price for its services
determined on a fee-per-scan basis. The Company has 20, 84 and 77 contracts
that will expire, if not renewed or extended, in the fourth quarter of 1997,
and the years 1998 and 1999, respectively. The Company anticipates that it will
renew or extend substantially all of these contracts. The Company's contracts
typically offer tiered pricing with lower fees on incremental scans, allowing
customers to benefit from increased scan volumes and the Company to benefit
from the operating leverage associated with increased scan volumes.
Accordingly, tiered pricing enables the Company to retain customers who may be
considering purchasing their own MRI systems rather than renewing a contract
with a mobile provider. As of September 30, 1997, the Company had 356 MRI
customers under exclusive contracts which averaged approximately 24 months in
remaining length. Most of the Company's contracts are with hospitals that have
fewer than 200 beds, many of which may lack the financial resources or patient
volume to justify the purchase of an MRI system.
 
                                       2
<PAGE>
 
 
  Superior Customer Service and Strong Customer Relationships. The Company
positions itself as a service company rather than solely as an equipment
provider and competes on the basis of value-added services in addition to
price. The Company differentiates itself from competitors by aggressively
marketing its services to referring physicians, radiologists and hospital
administrators and by having the advanced imaging systems, trained
technologists, fleet management capabilities and fleet size to accommodate the
growing needs of its customers. Value-added services offered by the Company
include patient scheduling and pre-screening, insurance pre-authorization,
appointment confirmation, billing, managed care contracting, and management
reporting services. The Company often provides two technologists per mobile
system per shift and is therefore able to accommodate higher patient volume and
operate with greater efficiency, resulting in high customer satisfaction
levels. As a result, the Company enjoys strong customer relationships, having
added 146 net new MRI customers from January 1, 1995 through September 30, 1997
and renewed or extended 197 of its customer contracts in this period.
 
  Substantial Operating Leverage. Because of the significant amount of fixed
costs associated with operating an MRI system, MRI service providers benefit
from operating leverage, with increased utilization rates resulting in
significant increases in operating earnings and operating margins. The
Company's average scans per system per day increased to 7.2 for the nine months
ended September 30, 1997 from 6.7 for the nine months ended September 30, 1996.
 
  Favorable Payment Terms. Approximately 92% of the Company's billings are
direct to hospitals. The hospitals, in turn, generally pay the Company prior to
collecting from patients and third party payors. Accordingly, the Company's
exposure to uncollectible patient receivables is minimized. In addition,
management believes that the Company's average number of days sales outstanding
("DSO") of receivables, which was 45 days as of September 30, 1997, is among
the most favorable in the mobile MRI industry and more favorable than the DSO
of many health care companies.
 
  Experienced Management Team. The Company's senior management team has an
average of nine years of industry experience and six years of experience with
Alliance. The Company's senior and operating managers have successfully
developed and implemented sophisticated marketing, fleet management and
financial strategies which have enabled the Company to become the largest and
among the most efficient and profitable mobile MRI operators. Upon consummation
of the Transactions and after giving effect to the Company's option plans,
management will own in excess of 11% of the capital stock of the Company on a
fully diluted basis.
 
                               BUSINESS STRATEGY
 
  The Company's management team has developed and implemented a business
strategy designed to maximize return on invested capital and in turn increase
revenues and cash flow. The Company's revenues for the nine months ended
September 30, 1997 increased to $62.3 million from $49.1 million for the nine
months ended September 30, 1996. In addition, the Company's income before
extraordinary gain for the nine months ended September 30, 1997 increased to
$6.8 million from $5.1 million for the nine months ended September 30, 1996.
The Company achieved comparable customer revenue growth of 25.9% and 8.8%,
respectively, in the first nine months of 1997 and in the year ended December
31, 1996. In addition, during the three months ended September 30, 1997 the
Company added a total of eight net mobile MRI systems. Management believes that
the recent financial performance of the Company does not yet fully reflect the
benefit of these new systems.
 
  The primary components of the Company's business strategy are to (i) increase
scan volumes; (ii) maximize return on invested capital; (iii) expand the scope
of services provided; and (iv) pursue strategic acquisitions.
 
  Increase Scan Volumes. The Company believes that the demand for MRI
procedures will continue to grow as new applications are developed and MRI
continues to gain acceptance and replace other imaging modalities.
 
                                       3
<PAGE>
 
The Company has an opportunity to significantly increase its scan volumes by
both adding new customers and increasing scans performed for existing
customers. In response to the growing demand for MRI procedures, the Company
added 26 net MRI systems and 146 net new MRI customers from January 1, 1995 to
September 30, 1997. The Company expects to add 14 net new MRI systems by the
end of 1998. The Company's decision to purchase new systems is typically
predicated on obtaining new customer contracts which serve as the basis of
demand for the new MRI systems.
 
  Maximize Return on Invested Capital. The Company actively manages the
utilization of its MRI systems to maximize its return on invested capital
(i.e., the amount of cash flow generated by each system relative to the
carrying value of such system). In the nine months ended September 30, 1997,
the Company generated an annualized return on invested capital of 42.9%. The
Company typically upgrades the quality of its fleet in markets where demand is
greatest and redeploys less advanced systems in markets where demand is lower
in order to generate incremental cash flow. The Company estimates that, on
average, a system can be utilized in a high demand market for approximately
eight years when properly maintained and upgraded, after which time the system
can either be utilized in a market with less demand or traded in for a new
system.
 
  Expand the Scope of Services Provided. The Company intends to leverage its
national presence and customer service capabilities by introducing new
services, the demand for which management believes will increase as hospitals
continue to outsource departments and cost centers and seek incremental revenue
sources. The Company expects to expand into open MRI services, lithotripsy
services and full-service management of hospital radiology departments. Open
MRI systems are used on claustrophobic patients and patients whose size
prohibits them from entering traditional MRI systems. Management believes that
with the introduction of its first open MRI system in the fourth quarter of
1997, the Company will be the first operator to offer mobile open MRI service.
 
  Pursue Strategic Acquisitions. Management has designed an acquisition
strategy for the Company which capitalizes on the consolidation occurring in
the industry as well as the Company's ability to (i) access substantial and
lower cost financial resources; (ii) realize significant synergies, operating
expense reductions and overhead cost savings; (iii) apply its consolidation
strategy to expand outside of diagnostic imaging in related services; (iv)
utilize the Company's expertise in logistics and fleet management; and (v)
leverage the Company's existing customer relationships to expand into new
modalities.
 
  On October 20, 1997, Alliance announced the execution of a definitive
agreement to acquire Medical Consultants Imaging Co. ("MCIC"), a Cleveland,
Ohio based provider of mobile MRI services, CT services and other outsourced
healthcare services. The acquisition also includes MCIC's one-half interest in
an operating joint venture in Michigan. The purchase price consists of $13
million cash (subject to certain reductions) plus the assumption of
approximately $5 million in financing arrangements. MCIC operates 14 mobile MRI
systems and several other diagnostic imaging systems primarily in Ohio,
Michigan, Indiana and Pennsylvania. The transaction was completed on November
21, 1997. In addition, the Company is currently engaged in acquisition
discussions with several other MRI service providers. Management believes
future acquisitions will enable the Company to redeploy systems in overlapping
markets, resulting in higher utilization rates and the opportunity to increase
penetration in other markets.

                                THE TRANSACTIONS
 
  In connection with the completion of the Offering, Alliance intends to
consummate the Recapitalization pursuant to the Recapitalization Merger
Agreement. In connection with the Transactions, the Company expects to enter
into an agreement (the "Credit Agreement") providing for a $50 million term
loan facility (the "Term Loan Facility") and a $75 million revolving loan
facility (the "Revolving Loan Facility"), which will be available for the
Company's working capital requirements and to finance acquisitions.
 
  In connection with the Transactions, Apollo will invest $37.3 million and BT
Capital Partners, an affiliate of BT Alex. Brown Incorporated (the "BT
Investor"), will invest $2.7 million of cash equity in the Company
(collectively, the "Equity Investment"). Immediately following consummation of
the Transactions, Apollo will own approximately 84% of the outstanding common
stock of the Company (approximately 74% on a fully diluted basis) and the BT
Investor will own approximately 6% of the outstanding common stock of the
Company (approximately 5% on a fully diluted basis). In addition, Apollo and
the BT Investor will purchase $14.1 million and $0.9 million, respectively, of
the Company's Series F Preferred Stock. As part of the Recapitalization, common
stock of Alliance with a value of approximately $4.5 million will be retained
by existing stockholders of the Company, representing approximately 10% of the
outstanding common stock of the Company. In addition, immediately following
consummation of the Transactions, through a combination of (i) the continuation
of existing options (having an option value of approximately $0.5 million) to
purchase common stock of Alliance and (ii) the issuance of options pursuant to
the Company's new option plan (the "New Option Plan"), management will own in
excess of 11% of the equity of the Company on a fully-diluted basis.
 
  The Offering, the Recapitalization, the Equity Investment and the related
borrowings under the Credit Agreement are collectively referred to herein as
the "Transactions." The consummation of the Transactions will be concurrent,
and the Offering is conditioned upon the other Transactions. The approximate
sources and uses of funds in connection with the Transactions are presented in
the following table, assuming the Transactions occurred as of September 30,
1997 (dollars in millions):

                              financial resources or be permitted under the
                              terms of its other indebtedness to repurchase the
                              Notes. In addition, the Credit Agreement will
                              restrict the Company's ability to repurchase the
                              Notes, including pursuant to a Change of Control
                              Offer. The occurrence of a default under the
                              Indenture (as defined) will also cause a default
                              under the Credit Agreement. See "Description of
                              the Notes--Change of Control."
       
Certain Covenants...........  The indenture pursuant to which the Notes will be
                              issued (the "Indenture") will contain certain
                              covenants that, among other things, limit the
                              ability of the Company and its Restricted
                              Subsidiaries (as defined) to: incur additional
                              indebtedness, incur liens, pay dividends or make
                              certain other restricted payments, consummate
                              certain asset sales, enter into certain
                              transactions with affiliates, merge or
                              consolidate with any other person or sell,
                              assign, transfer, lease, convey or otherwise
                              dispose of all or substantially all of the assets
                              of the Company and impose restrictions on the
                              ability of a Restricted Subsidiary to pay certain
                              dividends or make certain payments to the
                              Company. See "Description of the Notes--Certain
                              Covenants."
 
Offers to Purchase..........
                              In the event of certain asset sales, the Company
                              will be required to offer to repurchase the Notes
                              at a price equal to 100% of their principal
                              amount plus accrued interest to the date of
                              purchase. See "Description of the Notes--Certain
                              Covenants--Limitation on Asset Sales."
 
Use of Proceeds.............  The Company intends to use the net proceeds from
                              the Offering to partially fund the Transactions.
                              See "Use of Proceeds."

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

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

                                 RISK FACTORS
 
  Prospective purchasers of the Notes should consider carefully the
information set forth below as well as all other information set forth in this
Prospectus, in evaluating an investment in the Notes.
 
SUBSTANTIAL LEVERAGE
 
  After giving effect to the Transactions, the Company's consolidated
indebtedness will be approximately $221.9 million. This high level of
indebtedness in comparison to historical indebtedness may reduce the
flexibility of the Company to respond to changing business and economic
conditions, as well as limit capital expenditures of the Company. The Credit
Agreement and the Indenture will include significant operating and financial
restrictions, such as limits on the Company's ability to incur indebtedness.
On a pro forma basis, after giving effect to the Transactions, the Company's
earnings would have been insufficient to cover fixed charges by $8.3 million
for the year ended December 31, 1996, and by $0.7 million for the nine months
ended September 30, 1997.
 
  The Company's high degree of leverage may have important consequences for
the Company, including: (i) the ability of the Company to obtain additional
financing for acquisitions, working capital, capital expenditures or other
purposes, if necessary, may be impaired or such financing may not be on terms
favorable to the Company; (ii) a substantial portion of the Company's cash
flow will be used to pay the Company's interest expense, which will reduce the
funds that would otherwise be available to the Company for its operations and
future business opportunities; (iii) a substantial decrease in net operating
cash flows or an increase in expenses of the Company could make it difficult
for the Company to meet its debt service requirements and force it to modify
its operations; (iv) the Company may be more highly leveraged than its
competitors which may place it at a competitive disadvantage; and (v) the
Company's high degree of leverage may make it more vulnerable to a downturn in
its business or the economy generally. Any inability of the Company to service
its indebtedness or obtain additional financing, as needed, would have a
material adverse effect on the Company. A significant portion of the
indebtedness to be incurred by the Company to finance the Transactions will
bear interest at variable rates. Any increase in the interest rates on the
Company's indebtedness will reduce funds available to the Company for its
operations and future business opportunities and will exacerbate the
consequences of the Company's leveraged capital structure.
 
RESTRICTIVE DEBT COVENANTS
 
  The Indenture will contain certain covenants that, among other things, limit
the ability of the Company and its Restricted Subsidiaries to incur additional
indebtedness, incur liens, pay dividends or make certain other restricted
payments, consummate certain asset sales, enter into certain transactions with
affiliates, incur indebtedness that is subordinate in right of payment to any
Senior Debt and senior in right of payment to the Notes, merge or consolidate
with any other person or sell, assign, transfer, lease, convey or otherwise
dispose of all of or substantially all of the assets of the Company and impose
restrictions on the ability of a Restricted Subsidiary to pay certain
dividends or make certain payments to the Company. See "Description of the
Notes--Certain Covenants." In addition, the Credit Agreement is expected to
contain a number of significant covenants that, among other things, will
restrict the ability of the Company to (i) declare dividends or redeem or
repurchase capital stock; (ii) prepay, redeem or purchase debt, including the
Notes; (iii) incur liens and engage in sale-leaseback transactions; (iv) make
loans and investments; (v) incur additional indebtedness; (vi) amend or
otherwise alter debt and other material agreements; (vii) make capital
expenditures; (viii) engage in mergers, acquisitions and asset sales; (ix)
enter into transactions with affiliates; and (x) alter the business it
conducts. The indebtedness outstanding under the Credit Agreement will be
guaranteed by substantially all of the Company's domestic subsidiaries and
will be secured by a first priority lien on substantially all of the
properties and assets of the Company and its subsidiaries, now owned or
acquired later, including a pledge of all of the shares of the Company's
existing and future subsidiaries and up to 65% of the shares of the Company's
future foreign subsidiaries which are owned by the Company or one of its
subsidiaries. In addition, under the Credit Agreement, the Company will also
be required to comply with financial covenants with respect to (i) a maximum
leverage
 
                                      10
<PAGE>
 
ratio; (ii) a minimum consolidated EBITDA; (iii) a minimum interest coverage
ratio; and (iv) a minimum fixed charge coverage ratio. If the Company were
unable to borrow under the Credit Agreement due to a default, it would be left
without sufficient liquidity. See "Description of the Credit Agreement."
 
REGULATION
 
  Many aspects of the medical industry in the United States, including the
Company's business, are subject to extensive federal and state government
regulation. Although the Company believes that its operations comply with
applicable regulations, there can be no assurance that subsequent adoption of
laws or interpretations of existing laws will not regulate, restrict or
otherwise adversely affect the Company's business.
 
  The marketing and operation of the Company's MRI and computed axial
tomography ("CT") systems are subject to state laws prohibiting the practice
of medicine by non-physicians. Management believes that its operations do not
involve the practice of medicine because all professional medical services
relating to its operations, such as the interpretation of the scans and
related diagnoses, are separately provided by licensed physicians not employed
by the Company. Further, the Company believes that its operations do not
violate state laws with respect to the rebate or division of fees.
 
  The Company is subject to federal and state laws which govern financial and
other arrangements between health care providers. These include the federal
Medicare and Medicaid anti-kickback statutes which prohibit bribes, kickbacks,
rebates and any other direct or indirect remuneration in return for or to
induce the referral of an individual to a person for the furnishing, directing
or arranging of services, items or equipment for which payment may be made in
whole or in part under Medicare, Medicaid or other federal health care
programs. Violation of the anti-kickback statute may result in criminal
penalties and exclusion from the Medicare and other federal health care
programs. Many states have enacted similar statutes which are not necessarily
limited to items and services paid for under Medicare or a federally funded
health care program. In recent years, there has been increasing scrutiny by
law enforcement authorities, the U.S. Department of Health and Human Services
("HHS"), the courts and Congress of financial arrangements between health care
providers and potential sources of patient and similar referrals of business
to ensure that such arrangements are not designed as mechanisms to pay for
patient referrals. HHS interprets the anti-kickback statute broadly to apply
to distributions of partnership and corporate profits to investors who refer
federal health care program patients to a corporation or partnership in which
they have an ownership interest and to payments for service contracts and
equipment leases that are designed to provide direct or indirect remuneration
for patient referrals or similar opportunities to furnish reimbursable items
or services. In July 1991, HHS issued "safe harbor" regulations that set forth
certain provisions which, if met, will assure that health care providers and
other parties who refer patients or other business opportunities, or who
provide reimbursable items or services, will be deemed not to violate the
anti-kickback statute. The Company is also subject to separate laws governing
the submission of false claims. The Company is a party to a partnership for
provision of MRI services. The Company believes that the partnership is in
compliance with the anti-kickback statute. The Company believes that its other
operations likewise comply with the anti-kickback statutes.
 
  A federal law, commonly known as the "Stark Law," also imposes civil
penalties and exclusions for referrals for "designated health services" by
physicians to certain entities with which they have a financial relationship
(subject to certain exceptions). "Designated health services" include, among
other things, MRI services. While implementing regulations have been issued
relating to referrals for clinical laboratory services, no implementing
regulations have been issued regarding the other designated health services,
including MRI services. In addition, several states in which the Company
operates have enacted or are considering legislation that prohibits "physician
self-referral" arrangements or requires physicians to disclose any financial
interest they may have with a health care provider to their patients to whom
they recommend that provider. Possible sanctions for violating these
provisions include loss of licensure and civil and criminal sanctions. Such
state laws vary from state to state and seldom have been interpreted by the
courts or regulatory agencies. Nonetheless, strict enforcement of these
requirements is likely. The Company believes its operations comply with these
federal and state physician self-referral laws.
 
                                      11

  In some states, a certificate of need ("CON") or similar regulatory approval
is required prior to the acquisition of high-cost capital items, including
diagnostic imaging systems or provision of diagnostic imaging services by the
Company or its customers. CON regulations may limit or preclude the Company
from providing diagnostic imaging services or systems. A significant increase
in the number of states regulating the Company's business within the CON or
state licensure framework could adversely affect the Company. Conversely,
repeal of existing CON regulations in jurisdictions where the Company has
obtained or operates under a CON could also adversely affect the Company. This
is an area of continuing legislative activity, and there can be no assurance
that the Company will not be subject to CON and licensing statutes in other
states in which it operates or may operate in the future. See "Business--
Regulation."
 
REIMBURSEMENT OF HEALTH CARE COSTS; COST CONTAINMENT PRESSURES; CONTRACTS
 
  The majority of payments to the Company are received directly from health
care providers, rather than from private insurers, other third party payors or
governmental entities. To a lesser extent, the Company's revenues are
generated from direct billings to patients or their medical payors which are
recorded net of contractual discounts and other arrangements for providing
services at discounted prices. Under current reimbursement regulations, the
Company is prohibited from billing the insurer or the patient directly for
services provided for hospital inpatients or outpatients. Payment to health
care providers by third party payors for the Company's diagnostic services
depends substantially upon such payors' reimbursement policies. Consequently,
those policies have a direct effect on health care providers' ability to pay
for the Company's services and an indirect effect on the Company's level of
charges. Ongoing concerns about rising health care costs may cause more
restrictive reimbursement policies to be implemented in the future.
Restrictions on reimbursements to health care providers may affect such
providers' ability to pay for the services offered by the Company and could
indirectly adversely affect the Company's financial performance. See
"Business--Reimbursement."
 
  The current health care environment is characterized by cost containment
pressures which the Company believes have resulted in decreasing revenues per
scan. Although scan prices appear to have stabilized, the Company expects
modest continuing downward pressure on pricing levels. Although the Company
has experienced increased scan volumes in 1995, 1996 and 1997, it has also had
periods of declining volumes in prior years, and there can be no assurance
that the recent positive trends will continue. Among other things, the Company
is subject to the risk that customers will cease using the Company's MRI
services upon expiration of contracts and purchase or lease their own MRI
systems. In the past, when this has occurred, the Company has generally been
able to obtain replacement customers. However, it is not always possible to
immediately obtain replacement customers, and some replacement customers have
been smaller facilities and have had lower scan volumes.
 
ACQUISITION STRATEGY
 
  The Company's expansion and acquisition strategy may require substantial
capital, and no assurance can be given that the Company will be able to raise
any necessary additional funds through bank financing or the issuance of
equity or debt securities. Sufficient funds may not be available on terms
acceptable to the Company, if at all. There can be no assurance that the
Company will be able to successfully integrate the operations of any future
acquisitions.
 
TECHNOLOGICAL CHANGE AND OBSOLESCENCE
 
  The Company's services require the use of state-of-the-art medical equipment
that has been characterized by rapid technological advances. Although the
Company believes that substantially all the MRI and CT systems it provides can
be upgraded to maintain their state-of-the-art character, the development of
new technologies or refinements of existing ones might make the Company's
existing systems technologically or economically obsolete, or cause a
reduction in the value of, or reduce the need for, the Company's systems. MRI
systems are currently manufactured by numerous companies. Competition among
manufacturers for a greater share of the MRI systems market may result in
technological advances in the capacity of these new systems. Consequently,
 
                                      12
<PAGE>
 
the obsolescence of the Company's systems may be accelerated. Although the
Company is aware of no substantial technological change, should such change
occur, there can be no assurance that the Company will be able to acquire the
new or improved systems which may be required to service its customers.
 
SUBORDINATION OF NOTES AND THE GUARANTEES
 
  The Notes and the Guarantees will be unsecured and subordinated to the prior
payment in full of all Senior Debt of the Company and all Guarantor Senior
Debt of the Guarantors, respectively. As of September 30, 1997, on a pro forma
basis after giving effect to the Transactions, the aggregate outstanding
principal amount of all Senior Debt would have been approximately $56.9
million. In the event of a bankruptcy, liquidation or reorganization of the
Company, the assets of the Company or the Guarantors will be available to pay
obligations on the Notes only after all Senior Debt of the Company or all
Guarantor Senior Debt of the Guarantors, as the case may be, has been paid in
full, and there may not be sufficient assets remaining to pay amounts due on
any or all of the Notes. In addition, the Company may not pay principal or
premium, if any, or interest on the Notes if any Senior Debt is not paid when
due or any other default on any Senior Debt occurs and the maturity of such
Senior Debt is accelerated in accordance with its terms, unless, in either
case, such amount has been paid in full or the default has been cured or
waived and such acceleration has been rescinded. In addition, if any default
occurs with respect to certain Senior Debt and certain other conditions are
satisfied, the Company may not make any payments on the Notes for a designated
period of time. Finally, if any judicial proceeding is pending with respect to
any such default in payment on any Senior Debt or other default with respect
to certain Senior Debt, or if the maturity of the Notes is accelerated because
of a default under the Indenture and such default constitutes a default with
respect to any Senior Debt, the Company may not make any payment on the Notes.
See "Description of the Notes--Subordination."
 
FRAUDULENT TRANSFER CONSIDERATIONS
 
  The payment of the consideration in the Recapitalization to the stockholders
of Alliance and the related financing (including the issuance of the Notes and
the Guarantees) may be subject to review under federal or state fraudulent
transfer laws. While the relevant laws may vary from state to state, under
such laws, if a court in a lawsuit by a creditor or a representative of
creditors of Alliance, such as a trustee in bankruptcy or one of such entities
as debtor-in-possession, were to find that, at the time of or after and giving
effect to the Transactions, Alliance (i) was insolvent or rendered insolvent
thereby, (ii) was engaged in a business or transaction for which its remaining
assets constituted unreasonably small capital, (iii) intended to incur, or
believed that it would incur, debts beyond its ability to pay as they matured,
or (iv) intended to hinder, delay or defraud creditors and, in the case of
clauses (i), (ii) and (iii), that Alliance did not receive reasonably
equivalent value or fair consideration in the Recapitalization, such court
could avoid all or a part of the payment of the consideration in the
Recapitalization and require that the stockholders, including stockholders
exercising appraisal rights, return such consideration to Alliance or to a
fund for the benefit of their respective creditors. In addition, if a court
were to find that Alliance came within any of clauses (i) through (iv) above,
Alliance, or its respective creditors or trustees in bankruptcy, could seek to
avoid the grant of security interests to the lenders under the Credit
Agreement or to subordinate or void altogether the Notes and the Guarantees.
This would result in an event of default with respect to such indebtedness
which, under the terms of such indebtedness (subject to applicable law), would
allow the lenders to terminate their obligations thereunder and to accelerate
payment of such indebtedness.
 
  The measure of insolvency for purposes of the foregoing will vary depending
upon the law of the jurisdiction which is being applied. There can be no
certainty as to what law a court would apply pursuant to applicable choice of
law provisions, although it is likely that a court would apply the law of the
state of incorporation of Alliance, federal bankruptcy law, the law of the
jurisdiction in which the headquarters of Alliance is located or the law of
the jurisdiction in which the Recapitalization is deemed to have occurred.
Generally, however, a company would be considered insolvent for purposes of
the foregoing if the sum of such company's debts is greater than all such
company's property at a fair valuation, or if the present fair saleable value
of such company's assets is less than the amount that will be required to pay
its probable liability on its existing debts as they become absolute and
matured. There can be no assurance, however, that a court would not
 
                                      13
<PAGE>
 
determine that Alliance was insolvent at the time of or after and giving
effect to the Recapitalization. In addition, there can be no assurance that a
court would not determine, regardless of whether Alliance was solvent, that
the Recapitalization constituted a fraudulent transfer on another of the
grounds listed above. Management believes that Alliance will be solvent
following the consummation of the Transactions.
 
REPURCHASE OF NOTES UPON A CHANGE OF CONTROL
 
  In the event of a Change of Control, the Company will be required to offer
to repurchase all of the outstanding Notes at a purchase price equal to 101%
of the aggregate principal amount thereof, plus accrued and unpaid interest,
if any, to the repurchase date. The Credit Agreement will prohibit the
repurchase of the Notes upon a Change of Control unless and until the
indebtedness under the Credit Agreement is repaid in full. There can be no
assurance that the Company will have sufficient funds available or will be
permitted by the Credit Agreement and any other indebtedness to repurchase the
Notes upon the occurrence of a Change of Control. The Change of Control
purchase feature of the Notes may in certain circumstances make more difficult
or discourage a takeover of the Company and, thus, the removal of incumbent
management. See "Description of the Notes--Change of Control."
 
RELIANCE ON KEY PERSONNEL
 
  The Company's success depends in large part upon a number of key management
personnel, principally Messrs. Zehner and Pino. The loss of the service of one
or more of its executive officers or other key management personnel could have
a material adverse effect on the Company. Messrs. Zehner and Pino have entered
into employment agreements and an agreement not to compete with Alliance which
will become effective at the effective time of the Recapitalization. See
"Management--Employment and Related Agreements."
 
COMPETITION
 
  The market for diagnostic imaging services and imaging systems is highly
competitive. In addition to direct competition from other mobile providers,
the Company competes with free-standing imaging centers and health care
providers that have their own diagnostic imaging systems and with equipment
manufacturers that sell or lease imaging systems to health care providers for
full-time installation. Some of the Company's direct competitors that provide
contract MRI services may have access to greater financial resources than the
Company. In addition, some of the Company's customers are capable of providing
the same services to their patients directly, subject only to their decision
to acquire a high-cost diagnostic imaging system, assume the associated
financial risk, employ the necessary technologists and satisfy applicable
licensure and CON requirements, if any.
 
CONTROL BY APOLLO; POTENTIAL CONFLICTS OF INTEREST
 
  Upon consummation of the Transactions, Apollo will own approximately 84% of
the outstanding common stock of the Company (approximately 74% on a fully
diluted basis). Accordingly, Apollo and its general partner will control the
Company and have the power to elect all of its directors, appoint new
management and approve any action requiring the approval of the holders of
shares of Alliance common stock, including adopting amendments to the
Company's certificate of incorporation and approving mergers or sales of
substantially all of the Company's assets. Apollo also holds a controlling
interest in SMT Health Services Inc. ("SMT"), a leading provider of mobile MRI
services in the Mid-Atlantic region of the United States and a competitor of
the Company. If acquisition or other opportunities in the MRI industry are
presented to Apollo, no assurance can be given that Apollo will offer such
opportunities to Alliance and not to SMT.
 
ABSENCE OF PUBLIC MARKET
 
  The Notes are a new issue of securities which have no established trading
market. It is expected that the Notes will be sold to a limited number of
investors. The Company has been advised by the Underwriters that they intend
to make a market in the Notes after the consummation of this Offering;
however, the Underwriters are not obligated to do so, and any such market-
making, if commenced, may be terminated at any time without notice. No
assurance can be given as to the liquidity of the trading market, if any, that
may develop for the Notes.

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

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

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

million (411,358 shares at $11.00 per share) with respect to the retained
shares, and $18.0 million related to the carrying value of Alliance's
preferred equity converted to common shares, resulting in a net payment for

(1) Net income (loss) includes special charges of $13.3 million for the year
    ended December 31, 1994 related to an equipment exchange transaction, the
    impairment of certain equipment, debt restructuring and employee
    severances; extraordinary gains (net of tax) of $6.3 million for the year
    ended December 31, 1996 related to the early extinguishment of debt; and
    an extraordinary gain (net of tax) of $1.3 million for the nine months
    ended September 30, 1997 related to the early extinguishment of debt.
(2) EBITDA is defined herein as income before income taxes, plus depreciation,
    amortization, net interest expense and other non-recurring items
    (principally non-cash). EBITDA is presented because the Company believes
    it is a widely accepted financial indicator of a company's ability to
    service and/or incur indebtedness. However, EBITDA should not be
    considered as an alternative to net income as a measure of operating
    results or to cash flows as a measure of liquidity in accordance with
    generally accepted accounting principles.
(3) EBITDA margin is defined herein as EBITDA divided by revenues. The Company
    believes EBITDA margin provides a comparative reference to measure EBITDA
    performance from period to period and against comparable sized companies
    in the industry and, as such, provides a supplemental mechanism to
    evaluate efficiency and overall operating performance.
(4) The substantial majority of historical capital expenditures have related
    to either major upgrades to existing systems or the replacement of older,
    less-advanced systems with new, state-of-the-art technologically advanced
    systems. As a result of these historical investments, the Company believes
    that it has upgraded substantially all of its systems and expects most of
    its capital expenditures for at least the next three to five years to
    relate to net fleet additions through new system purchases.
(5) Represents period over period revenue growth for customers that generated
    revenues for the entire term of both periods.
(6) For purposes of computing this ratio, earnings consist of income before
    income taxes plus fixed charges. Fixed charges consist of interest expense
    and one-third of the rent expense from long-term equipment operating
    leases, which management believes is a reasonable approximation of an
    interest factor. Earnings were insufficient to cover fixed charges by
    $20.0 million and $18.0 million for the years ended December 31, 1993 and
    1994, respectively.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion of the results of operations and financial
condition of Alliance should be read in conjunction with Alliance's
consolidated financial statements and notes thereto included elsewhere in this
Prospectus.
 
OVERVIEW
 
  The Company is a leading nationwide provider of diagnostic imaging services
and the largest operator of state-of-the-art mobile diagnostic imaging systems
and related outsourced radiology services in the United States. The Company
primarily provides MRI systems and services to hospitals and other health care
providers on a mobile, shared user basis. The Company also provides dedicated,
full-time MRI systems and services as well as full-service management of
imaging operations for selected hospitals. The Company's services enable small
to mid-size hospitals to gain access to advanced diagnostic imaging technology
and related value-added services without making a substantial investment in
equipment and personnel. The Company operates a fleet of 98 MRI systems and
services 356 MRI customers in 36 states under exclusive contracts with an
average remaining length of approximately 24 months as of September 30, 1997.
 
  The Company's revenues are principally a function of the number of systems
in service, scan volumes and fees per scan. The Company generates
substantially all of its revenues under exclusive one to eight-year contracts
with hospitals and health care providers. The Company's contracts typically
offer tiered pricing with lower fees per scan on incremental scans, allowing
customers to benefit from increased scan volumes and the Company to benefit
from the operating leverage associated with increased scan volumes. The
Company expects modest continuing downward pressure on pricing levels as a
result of cost containment measures in the health care industry. However, in
many cases higher scan volumes justify lower prices on incremental scans.
 
  The principal components of the Company's operating costs include salaries
paid to technologists and drivers, annual system maintenance costs, insurance
and transportation costs. Because a majority of these expenses are fixed,
increased revenues as a result of higher scan volumes significantly improve
the Company's profitability while lower scan volumes result in lower
profitability.
 
  Since the beginning of 1995, Alliance has substantially increased revenues
by adding new customers and increasing scan volumes at existing customer
sites. During the same period, the growth rate of Alliance's EBITDA and net
income increased more rapidly than the growth rate of revenues as a result of
spreading costs (which are primarily fixed) over a larger revenue base and
implementing cost reduction and containment measures.
 
  Alliance has historically focused on maximizing cash flow and return on
invested capital nationwide, deploying new and upgraded systems in high volume
markets and redeploying older, less advanced systems with lower carrying
values in lower volume markets. Alliance's ongoing equipment trade-in and
upgrade program has substantially improved the marketability and productivity
of its MRI systems. Because Alliance owns substantially all of its MRI
systems, it periodically evaluates its older, less marketable MRI systems to
determine if it is more beneficial to continue to use such systems in lower
volume markets, which are profitable but produce less revenue, or to trade in
such equipment in connection with new system purchases. Since January 1, 1995,
Alliance has invested approximately $78 million to upgrade and expand its
fleet and currently maintains one of the most advanced fleets in the industry.
 
  The Company also provides CT services and imaging systems. Revenues from CT
services and imaging systems accounted for less than 5% of the Company's
revenues for the year ended December 31, 1996.
 
  On July 23, 1997, Alliance entered into the Recapitalization Merger
Agreement, pursuant to which, among other things, a subsidiary of the
Investor, subject to the terms and conditions of the Recapitalization Merger
Agreement, will be merged with and into Alliance. Immediately following the
Recapitalization, Apollo will own
 
                                      27
<PAGE>
 
approximately 84% of the issued and outstanding common stock of Alliance and
Alliance's existing shareholders will own approximately 10%. See "The
Transactions." The pro forma effect of the Transactions is set forth under
"Unaudited Pro Forma Consolidated Financial Information" and the notes thereto
included elsewhere in this Prospectus.
 
  On October 20, 1997, the Company announced execution of a definitive
agreement to acquire MCIC, a Cleveland, Ohio based provider of mobile MRI
services, CT services and other outsourced healthcare services. The
acquisition also includes MCIC's one-half interest in an operating joint
venture in Michigan. The purchase price consists of $13 million cash plus the
assumption of approximately $5 million in financing arrangements. MCIC
operates 14 mobile MRI systems and several other diagnostic imaging systems,
primarily in Ohio, Michigan, Indiana and Pennsylvania. The transaction was
completed on November 21, 1997. This transaction will be primarily funded from
existing cash reserves and debt assumed. Additional investments of this nature
may be made in the future (subject to certain conditions contained in the
Company's long-term financing arrangements) from a combination of cash
reserves, cash flow from operations, common or preferred equity and the
Revolving Loan Facility.
 
RESULTS OF OPERATIONS
 
NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1996.
 
  Revenues for the first nine months of 1997 were $62,285,000, an increase of
$13,188,000 or 26.9%, over 1996. This increase reflects a scan-based MRI
revenue increase of $11,706,000, or 26.9% ($2,515,000 or 5.8% as a result of
MRI operations acquired subsequent to the first quarter of 1996), resulting
from a 29.2% increase in total scan volume partially offset by a 1.8% decrease
in the average revenue realized per MRI scan. The average daily scan volume
per MRI system increased 7.5% to 7.2 from 6.7 in 1996. Management attributes
the volume increase to the Company's continuing MRI systems upgrade program,
which has enabled the Company to obtain new, long-term contracts from both
existing and new customers, and to the effect of marketing programs
implemented in early 1997. Management believes the decrease in average revenue
realized per scan is the result of: many customers achieving discount price
levels on incremental scan volumes; obtaining contracts with customers that
have high scan volumes which justify lower scan prices; and continuing
competitive pressure in the MRI service industry and cost containment efforts
by health care payors. CT revenues increased $782,000, or 29.4%, as a result
of internal growth and the fourth quarter 1996 acquisition of a small CT
business. Other revenues increased $548,000 primarily as a result of the
implementation in late 1996 of a program providing management services for a
large portfolio of imaging systems owned by others.
 
  The Company operated 98 MRI systems at September 30, 1997 compared to 86 MRI
systems at September 30, 1996. The average number of MRI systems operated by
the Company was 89 during the first nine months of 1997, compared to 84 during
the first nine months of 1996.
 
  Operating expenses, excluding depreciation, totaled $27,499,000 in the first
nine months of 1997, an increase of $3,950,000, or 16.8%, from the first nine
months of 1996. Payroll and related employee expenses increased $2,028,000, or
19.1%, primarily as a result of an increase in operating staffing levels
necessary to support revenue growth. Repairs and maintenance expense increased
$477,000, or 40.0%, due to an increased number of systems in service. Fuel and
other vehicle expenses collectively increased $387,000, or 36.8%, primarily
due to increasing fuel prices and the addition of new mobile MRI systems.
Preventative maintenance and cryogen contract expense increased $186,000, or
2.8%, due to the expiration of the warranties on an increased number of MRI
systems. Other operating expenses (including insurance, site fees, office
expenses, equipment rental, supplies and professional services) increased
$872,000, or 21.0%, as a result of the increased level of operations.
 
  Depreciation expense during the first nine months of 1997 totaled
$11,222,000, an increase of $2,052,000, or 22.4%, from the 1996 level
principally due to a higher amount of depreciable assets associated with
equipment additions and upgrades. Amortization expense during the first nine
months of 1997 increased $458,000, or 35.0%, over the 1996 period as a result
of goodwill amortization associated with recent business acquisitions.
 
 
                                      28
<PAGE>
 
  Selling, general and administrative expenses totaled $6,251,000 in the first
nine months of 1997, an increase of $1,372,000, or 28.1%, from the same period
in 1996. Professional services expenses increased $566,000, or 147.0%,
primarily due to costs associated with increased investor relations efforts
and merger and acquisition activity. Payroll and related expenses increased
$436,000, or 12.0%, primarily as a result of increased staffing levels
necessary to support the Company's increased level of operations. Other
expenses increased primarily as a result of expanded marketing programs and
costs associated with relocating the Company's corporate offices.
 
  Interest expense of $5,315,000 in the first nine months of 1997 was
$1,131,000, or 27.0%, higher than the same period in 1996, as a result of
higher average outstanding debt balances during 1997 as compared to 1996. This
increase was primarily related to the senior bridge loan (which was converted
into Series D convertible preferred stock on March 26, 1997) and to the
financing of several new imaging systems during the first nine months of 1997.
 
  An income tax provision of $3,480,000 was recorded in the first nine months
of 1997, which was higher than the tax provision recorded in the same period
in 1996 by $2,525,000, or 264.4%. The increase resulted from the increase in
income before taxes and an increase in the Company's effective tax rate. The
effective income tax rate increased to 34.0% in 1997 from 15.9% in 1996
because the Company's taxable income in 1997 is expected to exceed remaining
available net operating loss carryforwards.
 
  The Company's income before extraordinary gain was $6,751,000 in the first
nine months of 1997 compared to net income of $5,051,000 in the first nine
months of 1996, an increase of $1,700,000, or 33.7%, primarily attributable to
the increase in revenues achieved without a proportionate increase in costs
and administrative expenses. The Company reported an extraordinary gain, net
of income taxes, in the first quarter of 1997 of $1,332,000 on early
extinguishment of debt in January 1997.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  Revenues for 1996 were $68,482,000, an increase of $10,417,000, or 17.9%,
over 1995. On April 26, 1996, Alliance acquired all of the outstanding shares
of Royal Medical Health Services, Inc. ("Royal") and certain related assets.
Excluding revenues of $2,895,000 from operations which were sold in the second
half of 1995, the increase in revenues was $13,312,000, or 24.1%, with Royal
accounting for $4,694,000, or 8.5% of the increase. This increase reflects a
scan-based MRI revenues increase of $10,897,000, or 22.0%, ($4,532,000, or
9.2%, as a result of the Royal acquisition), resulting from a 23.4% increase
in total scan volume partially offset by a 1.1% decrease in the average
revenues realized per MRI scan. Royal accounted for 9.8% of the scan volume
increase and 0.1% of the offsetting price per scan decrease. The average
number of scans per day for each MRI system increased 15.5% to 6.7 in 1996
from 5.8 in 1995. Management attributes the non-Royal volume increase to
Alliance's continuing MRI systems upgrade program, which has enabled Alliance
to obtain new long-term contracts from both existing and new customers, and to
the effect of some smaller acquisitions. Management believes the decrease in
average revenues realized per scan is the result of: continuing competitive
pressure in the MRI service industry and cost containment efforts by health
care payors; obtaining contracts with customers that have high scan volumes
which justify lower scan prices; and many customers achieving discount price
levels on incremental scan volumes. Revenues under fixed fee contracts
increased $893,000, or 43.8%, resulting from an increased number of MRI
systems under such arrangements. Other revenues increased $891,000 primarily
as a result of Alliance selling its investment in London-based Alliance
Medical, Ltd. and recording a gain of $750,000. CT revenues increased
$632,000, or 21.8%, primarily as a result of the third quarter 1995 and fourth
quarter 1996 acquisitions of two CT businesses.
 
  Alliance operated 86 MRI systems at December 31, 1996 compared to 76 MRI
systems at December 31, 1995. The average number of MRI systems operated by
Alliance was 85 during 1996, compared to 74 during 1995.
 
                                      29

  Operating expenses, excluding depreciation, totaled $32,344,000 in 1996, an
increase of $4,002,000, or 14.1%, from 1995. Excluding expenses of $1,008,000
related to operations which were sold in the second half of 1995, the increase
in operating expenses was $5,010,000, or 18.3%, with Royal contributing
$2,333,000, or 8.5% of the increase. Payroll and related employee expenses
increased $1,789,000, or 15.0%, which was in line with the revenue increase.
Equipment rental expense increased $898,000, or 60.4%. The increase resulted
from higher number of rented MRI systems in operation and Alliance's leasing
of 20 new tractors in 1996. Other operating expenses increased $751,000, which
was offset by a $761,000 decrease in preventive maintenance contract and
cryogen expense, primarily as a result of more efficient systems and lower
contract rates associated with Alliance's equipment upgrade program.
 
  Depreciation expense during 1996 totaled $12,737,000, an increase of
$535,000, or 4.4%. Excluding depreciation expense of $638,000 related to
operations which were sold in the second half of 1995, depreciation expense
increased $1,173,000, or 10.1%, from the 1995 level principally due to a
higher amount of depreciable assets associated with equipment additions and
upgrades and the Royal acquisition. Amortization expense in 1996 increased
$607,000, or 45.1%, over the 1995 period as a result of the Royal acquisition
and four smaller acquisitions in late 1995 and 1996.
 
  Selling, general and administrative expenses totaled $8,130,000 in 1996, an
increase of $1,836,000, or 29.2%, from 1995. Excluding expenses of $369,000
related to operations sold in the second half of 1995, selling, general and
administrative expenses increased $2,205,000, or 37.2%. Payroll and related
expenses increased $1,457,000, primarily as a result of increased employee
compensation related to increased sales commissions, performance compensation
in connection with the increase in net income, early achievement of long term
incentive plan objectives and increased staffing levels. Bad debt expense
increase $567,000 in 1996 compared to 1995.
 
  Interest expense of $5,758,000 in 1996 was $705,000, or 14.0%, higher than
1995, primarily as a result of higher average outstanding debt balances during
1996 as compared to 1995. This increase related to debt assumed in connection
with the Royal acquisition and additional borrowing related to equipment
additions.
 
  An income tax provision of $1,060,000 was recorded in 1996. Alliance's pre-
tax income in 1996 was substantially offset by net operating loss
carryforwards; however, certain federal alternative minimum taxes and state
tax liabilities applied to this income, giving rise to the tax provision
recorded. In 1995, an income tax provision of $727,000 was recorded, also
related to certain federal alternative minimum taxes and state tax
liabilities. Alliance's 1996 effective tax rate of approximately 14% of pre-
tax income before extraordinary gains was comparable to the 1995 rate. At
December 31, 1996, Alliance had approximately $26,400,000 of net operating
loss carryovers available for federal regular income tax purposes to offset
future taxable income, subject to certain limitations. Approximately
$4,500,000 of this amount is not subject to such limitations; consequently,
approximately $6,700,000 of operating loss carryovers is available in 1997 for
regular federal income tax purposes. Alliance expects its future effective tax
rate to increase as these net operating loss carryovers are fully utilized.
 
  Alliance's net income before extraordinary gains was $6,501,000 in 1996
compared to net income of $4,102,000 in 1995, an increase of $2,399,000, or
58.5%, primarily attributable to the increase in revenues achieved without a
proportionate increase in operating and selling, general and administrative
expenses. Alliance reported extraordinary gains, net of income taxes, in the
fourth quarter of 1996 of approximately $6,300,000 on early extinguishment of
debt.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
  Revenues for 1995 were $58,065,000, an increase of $190,000, or 0.3%, over
1994. This increase reflects a $1,557,000 increase in MRI revenues under fixed
fee contracts and an increase in CT and other revenues totaling $125,000,
offset by a $1,492,000, or 2.9%, decrease in scan-based MRI revenues. The
decrease in scan-based MRI revenues resulted from a 5.8% increase in scan
volume offset by an 8.2% decrease in average revenues
 
                                      30

realized per MRI scan. Management attributes the volume increases to
Alliance's continuing MRI systems upgrade program, which has enabled Alliance
to obtain new long-term contracts from both existing and new customers. The
average number of scans per day for each MRI system remained unchanged at 5.8.
Management believes the decrease in average revenues realized per scan is the
result of continuing competitive pressure in the MRI service industry and cost
containment efforts by health care payors, as well as obtaining contracts with
customers that have high scan volumes which justify lower scan prices on
incremental scan volume. The increase in MRI revenues under fixed fee
contracts is a result of a higher number of systems deployed in full-time
temporary assignments, including several older systems awaiting trade-in on
new equipment. CT and other revenues increases are generally associated with
the acquisition of a mobile CT business and the gain on sale of equipment and
a related service contract, offset by lower other imaging revenue resulting
from the disposition of Alliance's full-service imaging center in Fresno,
California as of September 30, 1995. Alliance operated 76 MRI systems at
December 31, 1995, compared to 72 systems at December 31, 1994. The average
number of MRI systems operated by Alliance was 74 in 1995, compared with 73
during 1994.
 
  Operating expenses, excluding depreciation, totaled $28,342,000 in 1995, a
decrease of $2,751,000, or 8.8%, from 1994. Payroll and related employee
expenses decreased $336,000, or 2.7%, to $12,153,000 due to more efficient
staffing associated with cost reduction efforts and a larger number of systems
staffed by customer personnel in 1995. Maintenance and cryogen contract
expense declined $288,000, or 3.1%, to $9,079,000, as a result of an increased
number of newer, efficiently-operating systems in the fleet in 1995 and lower
contract rates, partially offset by an increased number of systems. Equipment
rental expense decreased $828,000, or 33.9%, to $1,618,000, as operating
leases expired and Alliance returned the related equipment to the lessor. The
leased equipment was generally replaced with low cost used MRI systems
purchased by Alliance. Professional medical services, supplies, site fees and
repairs expenses collectively decreased $1,443,000 or 40.0%, to $2,805,000,
primarily as a result of reduced physician staffing and other cost control
efforts at Alliance's full-service imaging center in Fresno, California, which
was disposed of effective September 30, 1995.
 
  Depreciation expense during 1995 decreased $1,222,000, or 9.1%, from the
1994 level due to a lower amount of depreciable assets, resulting from
equipment write-downs in late 1994, partially offset by equipment additions in
1995. Amortization expense in 1995 increased $402,000, or 42.6%, over 1994
because of the revision of the amortization period for goodwill from 40 to 25
years, effective October 1, 1994, and a small business acquisition in 1995.
 
  Selling, general and administrative expenses were essentially unchanged from
the prior year. Payroll and related employee expenses increased $629,000, or
15.7%, as a result of long-term deferred incentive compensation costs and
inflationary pressures. Bad debt expense decreased $609,000, or 100.0%, to
zero in 1995 as a result of revised billing practices and continuing intensive
collection efforts, primarily with respect to Alliance's retail accounts
receivable.
 
  Interest expense of $5,053,000 in 1995 was $5,705,000, or 53.0%, lower than
in 1994 primarily as a result of Alliance's comprehensive debt restructuring,
effective as of December 31, 1994, and lower average outstanding debt balances
in 1995.
 
  Alliance recorded special charges totaling $13,339,000 in the fourth quarter
of 1994. No such charges were incurred in 1995. Including these charges, the
loss before taxes totaled ($17,966,000) in 1994, compared to income before
taxes of $4,829,000 in 1995, an improvement of $22,795,000. Although the
preceding amounts before taxes are not representative of operating performance
in accordance with GAAP, they have been provided to highlight the significant
non-recurring element contained within the GAAP net income measurement. This
improvement resulted from significantly reduced operating expenses (including
depreciation), substantially lower interest expense and the absence of special
charges in 1995. Income before taxes in 1995 increased $9,456,000 over 1994's
loss before taxes without the effects of special charges.
 
  An income tax provision of $727,000 was recorded in 1995. Alliance's pre-tax
income in 1995 was substantially offset by net operating loss carryforwards;
however, certain federal alternative minimum taxes and
 
                                      31
<PAGE>
 
state tax liabilities applied to this income, giving rise to the tax provision
recorded. In 1994, an income tax provision of $1,100,000 was recorded as a
result of federal alternative minimum tax and certain state income taxes
related to cancellation of debt income for tax purposes associated with
Alliance's financial restructuring, as well as increased valuation allowances
for deferred tax assets. However, these reserved tax assets may be available
to reduce future income tax provisions. At December 31, 1995, Alliance had
approximately $33,000,000 in federal net operating loss carryforwards
available to offset future taxable income, subject to certain limitations.
 
  Alliance's net income was $4,102,000 in 1995, compared to a net loss of
($19,066,000) in 1994, an increase of $23,168,000, primarily attributable to
the increased operating profits, lower interest expense and absence of special
charges in 1995, as explained above. Net income in 1995 increased $9,354,000
over the net loss in 1994 without the effect of the special charges and
related tax impact. Although the preceding amount of net loss excludes the
effects of special charges and income taxes is not representative of operating
performance in accordance with GAAP, it has been provided to highlight the
significant non-recurring element contained within the GAAP net loss
measurement. This increase is attributable to higher operating profit and
lower interest expense in 1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Alliance generated $12.8 million, $18.0 million and $21.7 million from
operating activities in 1994, 1995 and 1996, respectively, and $17.3 million
and $22.1 million in the first nine months of 1996 and 1997, respectively. The
increase in cash provided by operating activities reflects the increase in
scan volumes and improved operating performance. Capital expenditures,
consisting primarily of new equipment purchases, totaled $22.4 million, $11.4
million and $34.4 million in 1994, 1995 and 1996, respectively, and $34.2
million in the first nine months of 1997. Since January 1, 1995, Alliance has
upgraded 23 MRI systems and purchased 35 new MRI systems, including
replacement systems. As of December 31, 1996, Alliance had binding equipment
purchase commitments totalling approximately $29.2 million. Alliance expects
to purchase the equipment under these commitments in 1997 and finance such
purchases with installment debt primarily provided by the equipment
manufacturers.
 
  The Company's primary cash needs consist of capital expenditures and debt
service. The Company incurs capital expenditures for the purposes of (i)
providing routine upgrades of its MRI systems; (ii) replacing or making major
upgrades to older, less advanced systems with new state-of-the-art systems;
and (iii) purchasing new systems. The Company estimates that routine annual
upgrade expenditures average approximately $25,000 per system or approximately
$2.4 million in the aggregate, based on the fleet size at September 30, 1997.
In addition to these routine expenditures, the Company expects capital
expenditures to be approximately $12 million in the last three months of 1997
which reflects the anticipated purchase of eight new MRI systems, including
replacement systems. The Company expects capital expenditures to be
approximately $20 million in 1998, which includes the anticipated purchase of
10 new MRI systems and routine upgrade expenditures. The Company's decision to
purchase a new system is typically predicated on obtaining new or extending
existing customer contracts which serve as the basis of demand for the new
system.
 
  After giving effect to the Transactions, the Company will be capitalized
with $165.0 million of Notes, a $125.0 million Credit Agreement consisting of
a $50.0 million Term Loan Facility and a $75.0 million Revolving Loan
Facility, $6.9 million of other obligations and $15.0 million of Series F
Preferred Stock. The Notes will bear interest at the rate per annum set forth
on the cover page of this Prospectus, payable semiannually, and will require
no principal repayments until maturity. The Term Loan will mature on the sixth
anniversary of the initial borrowing and will require annual principal
repayments of $0.5 million per year during the first five years and $47.5
million in the sixth year. The Revolving Loan Facility will mature on the
fifth anniversary of the initial borrowing and will have mandatory commitment
reductions of $37.5 million on the fourth and fifth anniversaries of the
initial borrowing. The interest rate under the Credit Agreement is expected to
be based on LIBOR. The Credit Agreement will contain restrictive covenants
which, among other things, limit the incurrence of additional
 
                                      32
<PAGE>
 
indebtedness, dividends, transactions with affiliates, asset sales,
acquisitions, mergers and consolidations, liens and encumbrances, and
prepayments of other indebtedness. In addition, the Credit Agreement will
require loans to be prepaid with 100% of the net proceeds of non-ordinary-
course asset sales or other dispositions of property, issuances of debt
obligations and certain preferred stock and certain insurance proceeds, 75% of
annual excess cash flow and 50% of the net proceeds from common equity and
certain preferred stock issuances, in each case subject to limited exceptions.
Voluntary prepayments are permitted in whole or in part. See "Description of
the Credit Agreement". The Series F Preferred Stock will pay dividends at the
rate of 13.5% per annum, payable quarterly in arrears, with such dividends
payable in kind at the option of the Company for the first five years from the
issue date. The Series F Preferred Stock is mandatorily redeemable for its
liquidation preference plus accrued and unpaid dividends on the 10th
anniversary of the issue date. The Series F Preferred Stock is redeemable at
the option of the Company prior to the 10th anniversary at premiums (expressed
as a percentage of the accreted face value) declining over ten years from
13.5% to 0%. The Company does not currently intend to pay dividends in cash on
the Series F Preferred Stock prior to the fifth anniversary of the issue date
and does not currently intend to redeem the Series F Preferred Stock prior to
the mandatory redemption date.
 
  The Company believes that after giving effect to the Transactions and the
incurrence of indebtedness related thereto, based on current levels of
operations and anticipated growth, its cash from operations, together with
other available sources of liquidity, including borrowings available under the
Revolving Loan Facility, will be sufficient over the next several years to
fund anticipated capital expenditures and make required payments of principal
and interest on its debt, including payments due on the Notes and obligations
under the Credit Agreement. In addition, the Company continually evaluates
potential acquisitions and expects to fund such acquisitions from its
available sources of liquidity, including borrowings under the Revolving Loan
Facility.
 
  The Company's expansion and acquisition strategy may require substantial
capital, and no assurance can be given that the Company will be able to raise
any necessary additional funds through bank financing or the issuance of
equity or debt securities on terms acceptable to the Company, if at all.

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

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

                                   BUSINESS
 
GENERAL
 
  The Company is a leading nationwide provider of diagnostic imaging services
and the largest operator of state-of-the-art mobile diagnostic imaging systems
and related outsourced radiology services in the United States. The Company
primarily provides MRI systems and services to hospitals and other health care
providers on a mobile, shared user basis. The Company also provides dedicated,
full-time MRI systems and services as well as full-service management of
imaging operations for selected hospitals. The Company's services enable small
to mid-size hospitals to gain access to advanced diagnostic imaging technology
and related value-added services without making a substantial investment in
equipment and personnel. The Company operates a fleet of 98 MRI systems and
services 356 MRI customers in 36 states under exclusive contracts with an
average remaining length of approximately 24 months as of September 30, 1997.
 
  Since the beginning of 1995, Alliance has substantially increased revenues
by adding new customers and increasing scan volumes at existing customer
sites. During the same period, the growth rate of Alliance's EBITDA and net
income has exceeded the growth rate of revenues principally as a result of
spreading costs (which are primarily fixed) over a larger revenue base and
implementing cost reduction and containment measures.
 
COMPETITIVE STRENGTHS
 
  The Company attributes its market leadership and its significant
opportunities for continued growth and increased profitability to the
following strengths:
 
  Largest Provider of Mobile MRI Services. The Company operates 98 MRI systems
in 36 states. The Company believes that the next largest mobile operator has a
fleet of approximately 70 MRI systems. Compared to its smaller competitors,
the Company believes it benefits from (i) significant equipment purchasing
savings; (ii) attractive service and maintenance contracts from its primary
equipment suppliers; (iii) strong name recognition and a reputation for
quality service; (iv) substantial financial flexibility and access to lower-
cost capital; and (v) the ability to efficiently deploy systems in a manner
which maximizes fleet utilization while satisfying customer requirements.
 
  Technologically Advanced MRI Fleet. The Company has invested approximately
$78 million since January 1, 1995 to replace and upgrade existing systems and
to purchase new systems. As a result, the Company believes that it has
upgraded substantially all of its systems and expects most of its capital
expenditures for at least the next three to five years to relate to new system
purchases. Of the Company's 98 MRI systems, 73 are state-of-the-art, high-
field 1.0 or 1.5 Tesla systems and 13 are state-of-the-art, mid-field 0.5
Tesla systems. The Company believes its fleet is among the newest and most
advanced in the industry, enabling the Company to perform a wider variety and
greater volume of scans and produce higher quality images, which the Company
believes provides a significant competitive advantage. Moreover, all of the
Company's state-of-the-art systems are designed to facilitate hardware and
software upgrades. As a result, the Company's systems should remain on the
leading edge of technological developments. In addition, while many of its
competitors lease their systems, the Company owns the vast majority of its
systems, generally providing greater flexibility and lower costs over the life
of the systems.
 
  Exclusive, Long-Term Contracts in Attractive Markets. The Company generates
substantially all of its revenues from exclusive, long-term contracts with
hospitals and other health care providers, with the price for its services
determined on a fee-per-scan basis. The Company has 20, 84 and 77 contracts
that will expire, if not renewed or extended, in the fourth quarter of 1997,
and the years 1998 and 1999, respectively. The Company anticipates that it
will renew or extend substantially all of these contracts. The Company's
contracts typically offer tiered pricing with lower fees on incremental scans,
allowing customers to benefit from increased scan volumes and the Company to
benefit from the operating leverage associated with increased scan volumes.
Accordingly, tiered pricing enables the Company to retain customers who may be
considering purchasing their
 
                                      36
<PAGE>
 
own MRI systems rather than renewing a contract with a mobile provider. As of
September 30, 1997, the Company had 356 MRI customers under exclusive
contracts which averaged approximately 24 months in remaining length. Most of
the Company's contracts are with hospitals that have fewer than 200 beds, many
of which may lack the financial resources or patient volume to justify the
purchase of an MRI system.
 
  Superior Customer Service and Strong Customer Relationships. The Company
positions itself as a service company rather than solely as an equipment
provider and competes on the basis of value-added services in addition to
price. The Company differentiates itself from competitors by aggressively
marketing its services to referring physicians, radiologists and hospital
administrators and by having the advanced imaging systems, trained
technologists, fleet management capabilities and fleet size to accommodate the
growing needs of its customers. Value-added services offered by the Company
include patient scheduling and pre-screening, insurance pre-authorization,
appointment confirmation, billing, managed care contracting, and management
reporting services. The Company often provides two technologists per mobile
system per shift and is therefore able to accommodate higher patient volume
and operate with greater efficiency, resulting in high customer satisfaction
levels. As a result, the Company enjoys strong customer relationships, having
added 146 net new MRI customers from January 1, 1995 through September 30,
1997 and renewed or extended 197 of its customer contracts in this period.
 
  Substantial Operating Leverage. Because of the significant amount of fixed
costs associated with operating an MRI system, MRI service providers benefit
from operating leverage, with increased utilization rates resulting in
significant increases in operating earnings and operating margins. The
Company's average scans per system per day increased to 7.2 for the nine
months ended September 30, 1997 from 6.7 for the nine months ended September
30, 1996.
 
  Favorable Payment Terms. Approximately 92% of the Company's billings are
direct to hospitals. The hospitals, in turn, generally pay the Company prior
to collecting from patients and third party payors. Accordingly, the Company's
exposure to uncollectible patient receivables is minimized. In addition,
management believes that the Company's average number of DSO of receivables,
which was 45 days as of September 30, 1997, is among the most favorable in the
mobile MRI industry and more favorable than the DSO of many health care
companies.
 
  Experienced Management Team. The Company's senior management team has an
average of nine years of industry experience and six years of experience with
Alliance. The Company's senior and operating managers have successfully
developed and implemented sophisticated marketing, fleet management and
financial strategies which have enabled the Company to become the largest and
among the most efficient and profitable mobile MRI operators. Upon
consummation of the Transactions and after giving effect to the Company's
option plans, management will own in excess of 11% of the capital stock of the
Company on a fully diluted basis.
 
BUSINESS STRATEGY
 
  The Company's management team has developed and implemented a business
strategy designed to maximize return on invested capital and in turn increase
revenues and cash flow. The Company's revenues for the nine months ended
September 30, 1997 increased to $62.3 million from $49.1 million for the nine
months ended September 30, 1996. In addition, the Company's income before
extraordinary gain for the nine months ended September 30, 1997 increased to
$6.8 million from $5.1 million for the nine months ended September 30, 1996.
The Company achieved comparable customer revenue growth of 25.9% and 8.8%,
respectively, in the first nine months of 1997 and in the year ended December
31, 1996. In addition, during the three months ended September 30, 1997, the
Company added a total of eight net mobile MRI systems. Management believes
that the recent financial performance of the Company does not yet fully
reflect the benefit of these new systems.
 
  The primary components of the Company's business strategy are to (i)
increase scan volumes; (ii) maximize return on invested capital; (iii) expand
the scope of services provided; and (iv) pursue strategic acquisitions.
 
  Increase Scan Volumes. The Company believes that the demand for MRI
procedures will continue to grow as new applications are developed and MRI
continues to gain acceptance and replace other imaging modalities.
 
                                      37
<PAGE>
 
The Company has an opportunity to significantly increase its scan volumes by
both adding new customers and increasing scans performed for existing
customers. In response to the growing demand for MRI procedures, the Company
added 26 net MRI systems and 146 net new MRI customers from January 1, 1995 to
September 30, 1997. The Company expects to add 14 net MRI systems by the end
of 1998. The Company's decision to purchase new systems is typically
predicated on obtaining new customer contracts which serve as the basis of
demand for the new MRI systems.
 
  Maximize Return on Invested Capital. The Company actively manages the
utilization of its MRI systems to maximize its return on invested capital
(i.e., the amount of cash flow generated by each system relative to the
carrying value of such system). In the nine months ended September 30, 1997,
the Company generated an annualized return on invested capital of 42.9%. The
Company typically upgrades the quality of its fleet in markets where demand is
greatest and redeploys less advanced systems in markets where demand is lower
in order to generate incremental cash flow. The Company estimates that, on
average, a system can be utilized for approximately eight years in a high
demand market when properly maintained and upgraded, after which time the
system can either be utilized in a market with less demand or traded in for a
new system.
 
  Expand the Scope of Services Provided. The Company intends to leverage its
national presence and customer service capabilities by introducing new
services, the demand for which management believes will increase as hospitals
continue to outsource departments and cost centers and seek incremental
revenue sources. The Company expects to expand into open MRI services,
lithotripsy services (which involves the utilization of sound waves to
eliminate kidney stones and urinary calculus in the bladder) and full-service
management of hospital radiology departments. Open MRI systems are used on
claustrophobic patients and patients whose size prohibits them from entering
traditional MRI systems. Management believes that with the introduction of its
first open MRI system in the fourth quarter of 1997, the Company will be the
first operator to offer mobile open MRI service.
 
  Pursue Strategic Acquisitions. Management has designed an acquisition
strategy for the Company which capitalizes on the consolidation occurring in
the industry as well as the Company's ability to (i) access substantial and
lower cost financial resources; (ii) realize significant synergies, operating
expense reductions and overhead cost savings; (iii) apply its consolidation
strategy to expand outside of diagnostic imaging in related services; (iv)
utilize the Company's expertise in logistics and fleet management; and (v)
leverage the Company's existing customer relationships to expand into new
modalities.
 
  On October 20, 1997, Alliance announced the execution of a definitive
agreement to acquire MCIC, a Cleveland, Ohio based provider of mobile MRI
services, CT services and other outsourced healthcare services. The
acquisition also includes MCIC's one-half interest in an operating joint
venture in Michigan. The purchase price consists of $13 million cash plus the
assumption of approximately $5 million in financing arrangements. MCIC
operates 14 mobile MRI systems and several other diagnostic imaging systems,
primarily in Ohio, Michigan, Indiana and Pennsylvania. The transaction was
completed on November 21, 1997. In addition, the Company is currently engaged
in acquisition discussions with several other MRI service providers.
Management believes future acquisitions will enable the Company to redeploy
systems in overlapping markets, resulting in higher utilization rates and the
opportunity to increase penetration in other markets.
 
OPERATIONS
 
  Customer Base. The Company believes that many hospitals and other health
care providers require access to MRI services to remain competitive in the
health care marketplace. Regulatory and licensing requirements in many states
may also limit access to MRI systems. In addition, many health care providers
lack sufficient patient volume or financial resources to justify the purchase
of an MRI system. Such providers contract for mobile, shared-user systems or
single-user, full-time systems to gain access to MRI technology and to provide
comprehensive MRI services to their patients. In addition, many health care
providers, regardless of whether their patient utilization levels and
financial resources justify the purchase of an MRI system, prefer to contract
with
 
                                      38
<PAGE>
 
the Company for full-time or shared-user imaging systems to (i) obtain the use
of an MRI system without any capital investment or financial risk; (ii) retain
the ability to switch system types and avoid technological risk; (iii) obtain
MRI services in jurisdictions in which the use of the Company's services
facilitates the procurement of regulatory approvals; (iv) avoid future
uncertainty as to reimbursement policies; (v) eliminate the need to recruit,
train and manage qualified technologists; (vi) outsource their entire MRI
service to obtain access to needed technology while avoiding financial
investment or risk and obtaining management expertise; or (vii) provide
additional imaging services when patient demand exceeds their in-house
capability.
 
  The Company's MRI and CT services, which include imaging systems,
technologists and support services, are provided on both a mobile, shared-user
basis and on a full-time basis to single customers. As of September 30, 1997,
the Company provided imaging systems and related technologists and support
services to 389 customers (356 for MRI services and 60 for CT services; some
customers contract for both modalities) consisting primarily of small to mid-
sized hospitals (i.e., hospitals with 50-200 beds). The Company believes that
many of such hospitals lack the patient volume or financial resources to
justify the purchase of an MRI system. As of September 30, 1997, the Company
provided services and equipment to customers in 36 states.
 
  Typically, the Company's MRI systems are contracted on average for five to
six days a week. The Company believes that as customers become familiar with
the basic or expanded technology and its applications, the corresponding MRI
system's rate of usage generally increases, causing the number of scans per
day to increase and eventually leading to requests for additional days of
usage.
 
  Contract Terms. Contract fees are charged on a fee-per-scan, fee-per-day or
fee-per-month basis (with numerous variations within each billing method to
accommodate particular customers' needs). Generally, the Company provides
technologists under contracts billed on a fee-per-scan or fee-per-day basis
but not under contracts billed on a fee-per-month basis. Although a typical
contract offers daily flat-rate options, most customers currently pay on a
fee-per-scan basis. The amount of fees paid on this basis depends upon the
type of imaging system provided, the term of the contract, the types and
number of scans performed as well as the day of the week on which scans are
performed. The contracts typically allow the Company to reduce the number of
days of service provided based upon the customer's scan volume, or to
terminate the contract if the Company is unable to realize a profit on the
services provided. The Company typically enters into exclusive, one to eight
year contracts that include automatic renewal provisions. In addition, the
Company's marketing representatives consistently seek to renew and extend
contracts prior to expiration. From January 1, 1995 through September 30,
1997, the Company renewed or extended 197 of its customer contracts. As of
September 30, 1997, the Company's contracts averaged approximately 24 months
in remaining length.
 
  Imaging Systems. At September 30, 1997, the Company operated 98 MRI systems
and 14 CT systems. Of the 98 MRI systems, 73 are state-of-the-art, high-field
1.0 or 1.5 Tesla systems and 13 are state-of-the-art, mid-field 0.5 Tesla
systems. These systems are designed to facilitate hardware and software
upgrades. As a result, the Company's systems should remain at the leading edge
of technological developments. Further, of the 98 MRI systems, 86 are housed
in mobile coaches and 12 are housed in relocatable modular buildings on
hospital campuses or installed in the hospital facility. Substantially all of
the imaging systems are owned by the Company. One of such systems is a fixed-
site system at a large hospital in Georgia operated by a partnership of which
a subsidiary of the Company is a partner.
 
  The Company orders substantially all of its imaging systems from major
medical device manufacturers, primarily General Electric Medical Systems,
Siemens Medical Systems and Picker International. Generally, the Company
orders its imaging systems from such major manufacturers while simultaneously
contracting with health care providers for their use, thereby reducing the
Company's system utilization risk. The Company's MRI systems are installed in
specially-designed trailers or relocatable, modular buildings. The trailers
and relocatable modular buildings are designed jointly by the imaging system
manufacturer and the housing manufacturer and are designed to provide image
quality identical to those installed in hospital facilities.
 
                                      39
<PAGE>
 
  Fleet Management. The Company seeks to maximize cash flow and return on
assets by actively managing its fleet to maximize utilization. The Company
employs logistics management systems and redeploys or trades in older MRI
systems when it purchases new MRI systems. MRI systems are currently scheduled
for as little as one-half day and up to seven days per week at any particular
facility. Generally, technologists and a driver are assigned to each of the
mobile operating systems. Movement of the systems typically occurs at night
via a fleet of Company-owned or leased tractors. The drivers move the systems
and activate them upon arrival at each imaging site so that the systems are
operational when the Company's technologists arrive on the following scheduled
imaging day.
 
  Regional Management. The Company's seven regional offices market, manage and
staff the operation of its imaging systems. The Company's regional offices are
located in Anaheim and Roseville, California; Pittsburgh, Pennsylvania;
Chicago, Illinois; Colorado Springs, Colorado; Burlington, Connecticut; and
Macon, Georgia. Each region has individuals responsible for sales and
operations management.
 
  Licensing and JCAHO Accreditation. Most states do not currently license MRI
providers such as the Company, although many do subject such providers to CON
requirements. Hospitals with which the Company has contracted are subject to a
variety of regulations and standards of state licensing and other authorities
and accrediting bodies such as the Joint Commission on Accreditation of
Healthcare Organizations ("JCAHO"). As an outside vendor, the Company may be
required to comply with such regulations and standards to enable the hospitals
with which it has contracted to maintain their permits, approvals and
accreditation. Alliance is in the process of seeking accreditation from JCAHO.
 
CUSTOMER SUPPORT
 
  As part of its full service package, the Company provides several levels of
support to a hospital or health care provider. The Company's technologists who
staff the MRI systems regularly work with the hospital radiologists, referring
physicians and nursing staff to perform the scans. The technologists also work
with regional technical advisors who are specialists in MRI technology and
consult on specialized technical problems, hold periodic training sessions for
the technologists, radiologists, referring physicians and health care
customers and provide problem-solving services. These specialists play a
central role in the Company's retention of accounts and building of scan
volumes. Management believes that targeted direct marketing at each hospital
with assigned responsibility for support services is a key element for
broadening the awareness of MRI technology, building scan volumes and
obtaining contract renewals.
 
SALES AND MARKETING
 
  Currently, the Company's sales force consists of 13 members who identify and
contact candidates for the Company's services each with the overall management
and sales responsibility for a specific region of the country. Direct
marketing plays a primary role in the Company's development of new customers.
The Company employs 18 full- and part-time marketing representatives who
develop scan volumes at existing and new customer locations by introducing the
Company's services to referring physicians and keeping such physicians
apprised of the Company's MRI service capabilities. In addition, certain of
the Company's executive officers and regional vice presidents spend a portion
of their time marketing the Company's services. The Company believes that
having senior managers involved in sales and contract negotiations enhances
its ability to obtain new and retain existing customers.
 
MAINTENANCE
 
  For its MRI and CT systems, the Company primarily relies upon the
manufacturer to provide maintenance and service under warranties and service
contracts. These service contracts require the Company to pay fixed monthly
fees or variable fees on a risk-sharing basis.
 
  Timely, effective service is essential to maintaining high utilization rates
on the Company's MRI systems. If the Company experiences greater than
anticipated malfunctions of its equipment or if it is unable to promptly
obtain the service necessary to keep its systems functioning effectively, its
business could be adversely affected.
 
                                      40
<PAGE>
 
  The Company contracts with the MRI equipment manufacturers for comprehensive
maintenance programs on its systems to minimize downtime (the period of time
equipment is unavailable during scheduled use hours because of malfunctions).
These maintenance contracts commence upon the expiration of the applicable
warranty period. The systems are generally warranted by the systems
manufacturer for a specified period of time, usually one year to eighteen
months from the date of purchase. During the warranty period and maintenance
contract term, the Company receives uptime guarantees (a guarantee that
equipment will function for a specified percentage of scheduled use hours.)
However, these guarantees are not expected to substantially compensate the
Company for loss of revenue for downtime.
 
REIMBURSEMENT
 
  Substantially all the Company's revenues are derived directly from health
care providers rather than from private insurers, other third party payors or
governmental entities. Consequently, the Company historically has not had
material direct exposure to, or direct connection with, patient billing,
collections or reimbursement by insurance companies, other third parties or
Medicare. However, to a lesser extent, the Company's revenues are generated
from direct billings to patients or their third party payors which are
recorded net of contractual discounts and other arrangements for providing
services at less than established patient billing rates. Net revenues from
direct patient billing amounted to approximately 8% of the Company's revenue
in 1996.
 
  Most private health care insurers, including various Blue Cross and Blue
Shield Plans, reimburse approximately 70% to 100% of the health care
provider's charge for MRI and CT scans. Such insurers may impose limits on
reimbursement for imaging services or deny reimbursement for tests that do not
follow recommended diagnostic procedures. Because patient reimbursement may
indirectly affect the levels of fees the Company can charge its customers by
constricting the health care providers' profit margin, widespread application
of restricted or denied reimbursement schedules could adversely affect the
Company's business. Conversely, at lower reimbursement rates, a health care
provider might find it financially unattractive to own an MRI or CT system,
but could benefit from purchasing the Company's services.
 
  Congress has attempted to restrict rising federal reimbursement costs under
the Medicare program by setting predetermined payment amounts for
reimbursement of inpatient services according to each patient's diagnosis
related group ("DRG"). Because a DRG rate compensates a hospital for all
services rendered to a patient, a hospital cannot be separately reimbursed by
Medicare for an MRI scan or other procedure performed on an inpatient. DRG
payment rates for inpatient services became effective in the early 1980's and
have been adjusted downward since then. Currently, those payment rates are not
applicable to outpatient services; instead, Medicare reimbursement for imaging
services furnished in a hospital outpatient setting is subject to alternative,
generally more favorable, payment limits tied to the physician fee schedule
described below. However, it is possible that DRG payment rates or other
limits might be implemented with respect to outpatient services in the future.
 
  Because payments have generally been less restricted in non-hospital
outpatient settings, in prior years there has been rapid growth in MRI systems
at non-hospital free-standing facilities which provide outpatient services.
HHS, as required by statute, has issued fee schedules for reimbursing
physicians who treat Medicare patients. Under these fee schedules, physician
reimbursement for professional services is based on a set of values assigned
to each service provided by a physician. The fee schedules also generally
apply to reimbursement for technical services (such as those provided by the
Company) except in limited circumstances. There can be no assurance that
Medicare payments will remain comparable to present levels. In particular, on
June 18, 1997, the Health Care Financing Administration ("HCFA") issued a
proposed rule affecting, among other things, the practice expense component of
the physician fee schedule, physician supervision requirements for certain
diagnostic tests and the adoption of a new definition of an independent
diagnostic testing facility. Under the proposed rule, the Relative Value Units
("RVU") for MRI scans would be relatively unchanged, but the RVUs for MRI
scans with contrast would be reduced significantly. The proposed effective
date of the rule is January 1, 1998. However, as part of federal budget
legislation recently signed into law, implementation of the practice expense
 
                                      41
<PAGE>
 
changes will be delayed until January 1, 1999, with a three year transition
period for implementing the new method for calculating practice expenses.
While the impact of the proposed changes is dependent on numerous factors,
including whether the proposed rule is adopted substantially in the proposed
form and whether the Company's hospital customers will seek similar
adjustments in payments to the Company for scans with contrast agents to the
extent they are currently charged additional amounts for contrast exams, there
can be no assurance that such practice expense changes will not, directly or
indirectly, have a material adverse effect on the Company's business or
results of operations.
 
  The Budget Reconciliation Act for 1998 that was recently signed into law
contains a number of changes to the Medicare program which will adversely
affect hospitals and which could therefore potentially have an impact on
suppliers of goods and services to hospitals, including the Company. In
particular, among other things, the Act requires implementation of a
prospective payment system for outpatient services beginning in 1999; and
reduces hospital inpatient reimbursement for both operating and capital
expenses compared with reimbursement levels that would have prevailed absent
any change in law. The Company believes that approximately 15% to 20% of its
hospital customers' MRI revenues are derived from Medicare patients.
 
REGULATION
 
  Many aspects of the health care industry in the United States, including the
Company's business, are subject to extensive federal and state government
regulation. Although the Company believes that its operations comply with
applicable regulations, there can be no assurance that subsequent adoption of
laws or interpretations of existing laws will not regulate, restrict or
otherwise adversely affect the Company's business.
 
  The marketing and operation of the Company's MRI and CT systems are subject
to state laws prohibiting the practice of medicine by non-physicians and the
rebate or division of fees between physicians and non-physicians. Management
believes that its operations do not involve the practice of medicine because
all professional medical services relating to its operations, such as the
interpretation of the scans and related diagnoses, are separately provided by
licensed physicians not employed by the Company. Further, the Company believes
that its operations do not violate state laws with respect to the rebate or
division of fees.
 
  The Company is subject to federal and state laws which govern financial and
other arrangements between health care providers. These include the federal
Medicare and Medicaid anti-kickback statutes which prohibit bribes, kickbacks,
rebates and any other direct or indirect remuneration in return for or to
induce the referral of an individual to a person for the furnishing, directing
or arranging of services, items or equipment for which payment may be made in
whole or in part under the Medicare, Medicaid or other federal health care
programs. Violation of the anti-kickback statute may result in criminal
penalties and exclusion from the Medicare and other federal health care
programs. Many states have enacted similar statutes which are not necessarily
limited to items and services paid for under the Medicare or a federally
funded health care program. In recent years, there has been increasing
scrutiny by law enforcement authorities, HHS, the courts and Congress of
financial arrangements between health care providers and potential sources of
patient and similar referrals of business to ensure that such arrangements are
not designed as mechanisms to pay for patient referrals. HHS interprets the
anti-kickback statute broadly to apply to distributions of partnership and
corporate profits to investors who refer federal health care program patients
to a corporation or partnership in which they have an ownership interest and
to payments for service contracts and equipment leases that are designed to
provide direct or indirect remuneration for patient referrals or similar
opportunities to furnish reimbursable items or services. In July 1991, HHS
issued "safe harbor" regulations that set forth certain provisions which, if
met, will assure that health care providers and other parties who refer
patients or other business opportunities, or who provide reimbursable items or
services, will be deemed not to violate the anti-kickback statute. The Company
is also subject to separate laws governing the submission of false claims. The
Company is a party to a partnership for the provision of MRI services. The
Company believes that the partnership is in compliance with the anti-kickback
statute. The Company believes that its other operations likewise comply with
the anti-kickback statutes.
 
                                      42
<PAGE>
 
  A federal law, commonly known as the "Stark Law," also imposes civil
penalties and exclusions for referrals for "designated health services" by
physicians to certain entities with which they have a financial relationship
subject to certain exceptions. "Designated health services" include, among
others, MRI services. While implementing regulations have been issued relating
to referrals for clinical laboratory services, no implementing regulations
have been issued regarding the other designated health services, including MRI
services. In addition, several states in which the Company operates have
enacted or are considering legislation that prohibits "physician self-
referral" arrangements or requires physicians to disclose any financial
interest they may have with a health care provider to their patients to whom
they recommend that provider. Possible sanctions for violating these
provisions include loss of licensure and civil and criminal sanctions. Such
state laws vary from state to state and seldom have been interpreted by the
courts or regulatory agencies. Nonetheless, strict enforcement of these
requirements is likely. The Company believes its operations comply with these
federal and state physician self-referral laws.
 
  In some states, a CON or similar regulatory approval is required prior to
the acquisition of high-cost capital items, including diagnostic imaging
systems or provision of diagnostic imaging services by the Company or its
customers. CON regulations may limit or preclude the Company from providing
diagnostic imaging services or systems. A significant increase in the number
of states regulating the Company's business within the CON or state licensure
framework could adversely affect the Company. Conversely, repeal of existing
CON regulations in jurisdictions where the Company has obtained or operates
under a CON could also adversely affect the Company. This is an area of
continuing legislative activity, and there can be no assurance that the
Company will not be subject to CON and licensing statutes in other states in
which it operates or may operate in the future.
 
LIABILITY INSURANCE
 
  While the Company's imaging systems are at a customer's facility, they
operate only under the direction of licensed physicians on the customer's
staff who direct the procedures, supervise the Company's technologists and
interpret the results of the examinations. Currently, there are no known
biological hazards associated with MRI. However, there is a risk of harm to a
patient who has a ferrous material or certain types of cardiac pacemakers
within his or her body. Patients are carefully screened to safeguard against
this risk. To protect against possible exposure for professional liability,
the Company maintains professional liability insurance.
 
COMPETITION
 
  The market for diagnostic imaging services and imaging systems is highly
competitive. In addition to direct competition from other mobile providers,
the Company competes with free-standing imaging centers and health care
providers that have their own diagnostic imaging systems and with equipment
manufacturers that sell or lease imaging systems to health care providers for
full-time installation. Some of the Company's direct competitors which provide
contract MRI services may have access to greater financial resources than the
Company. In addition, some of the Company's customers are capable of providing
the same services to their patients directly, subject only to their decision
to acquire a high-cost diagnostic imaging system, assume the associated
financial risk, employ the necessary technologists and satisfy applicable
licensure and CON requirements, if any. The Company competes against other MRI
service providers on the basis of quality of services, quality and magnetic
field strength of imaging systems, price, availability and reliability.
 
EMPLOYEES
 
  As of September 30, 1997, the Company had 501 employees, of whom
approximately 405 were trained diagnostic imaging technologists, patient
coordinators, technical support staff or other field operations personnel. Of
the Company's employees, 153 are employed on a part-time or "as needed" basis.
None of the Company's employees are represented by a labor organization and
the Company is not aware of any activity seeking such organization. The
Company considers its relations with its employees to be satisfactory.

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

Jay A. Mericle..............................  126,000  226,800  176,400  196,691
</TABLE>
 
  The actual amounts of cash compensation to Mr. Zehner, Mr. Pino and Mr.
White, Alliance's Chief Executive Officer, Chief Operating Officer and Chief
Financial Officer, respectively, were determined by the Compensation Committee
based on its evaluation of the extent to which Alliance's 1996 earnings per
share and cash flow budgets and individual objectives applicable to each
executive were achieved. The actual amounts of cash compensation to executives
responsible for the Company's various operating regions were determined by the
Compensation Committee based on its evaluation of the extent to which regional
operating profit budgets and individual objectives applicable to each such
executive were achieved. These amounts were generally more than the target
amounts because Alliance significantly exceeded its earnings per share, cash
flow and regional operating budgets. A predetermined percentage of the
possible compensation award above the minimum amount is determined with
respect to each of the criteria mentioned above for the respective officers.
 
                                NEW OPTION PLAN
 
  After the consummation of the Recapitalization, the Company will adopt an
employee option plan pursuant to which options with respect to a total of
454,545 shares of Alliance common stock will be available for grant, and Mr.
Zehner and Mr. Pino will be granted options to purchase 145,000 and 130,000
shares of Alliance common stock, respectively. Fifty percent of the option
shares will vest in equal increments over four years. Fifty percent of the
option shares will vest after seven and one half years (subject to
acceleration if certain per share equity targets are achieved). Vesting of the
options occurs only during an employee's term of employment. The exercise
price for the options is $11.00 per share and the options will expire ten
years from the date of grant.

(1) All options granted in 1996 vest on March 1, 2003; however, vesting of the
    1996 option shares will be accelerated based on achievement of the
    following per share stock prices for 15 consecutive trading days, as
    reported by Nasdaq: $4.75--25%; $5.50--50%; $6.25--75%; $7.00--100%;
    subject to a maximum vesting of one-third per year from February 29, 1996
    regardless of stock price (no limits after year three). As of March 15,
    1997, Alliance's stock price had achieved the first three accelerated
    vesting hurdles, and the 1996 options were two-thirds vested at such date.
 
(2) All options were granted at market value (based on the closing price as
    reported on the Nasdaq SmallCap Market on the business day prior to the
    grant date) at the date of grant.
 
(3) Valuations based upon the assumed rates of stock price appreciation are
    based upon appreciation over a ten-year period from the $3.5625 exercise
    price of the options. The 5% and 10% assumed annual rates of appreciation
    would result in the price of the Alliance's common stock increasing to
    $5.80 and $9.24 per share, respectively.

             LONG-TERM INCENTIVE PLAN--AWARDS IN LAST FISCAL YEAR
 
  In addition to the annual plan described above under "--Executive
Compensation Plan," Alliance instituted a long-term executive incentive plan
("LTIP") in 1995 to provide future awards in cash or equivalent amounts of
Alliance common stock to key executives. The objective of the plan is to
advance the long-term interests of Alliance and its stockholders by providing
substantial incentives to meet or exceed certain cash flow
 
                                      48

goals necessary to ensure that Alliance would be able to service its long-term
obligations on a continuing basis, and that it would be able to pay certain
preferred stock dividends in cash, thereby avoiding the substantial dilution
to existing common stockholders if such dividends were paid in common stock
equivalents. As of January 2, 1997, Alliance had retired all of its Series A
6% Redeemable Preferred Stock (the "Series A Preferred Stock"), thereby fully
satisfying the second objective of the LTIP.
 
  The following awards under the plan were earned by the Named Executive
Officers in 1996:

(1) Under the LTIP, amounts may be accrued with respect to each of the fiscal
    years from 1995 to 1998 based upon two factors: (a) the extent to which
    Alliance's actual earnings before depreciation, amortization, interest,
    taxes and equipment charges (as more precisely defined in the LTIP,
    "EBDIT") exceeds targeted EBDIT for such year and (b) the extent to which
    Alliance pays dividends on its Series A Preferred Stock in cash for such
    year (thereby avoiding the potential dilution to holders of common stock
    from the payment of dividends in common stock equivalents). As noted
    above, Alliance retired all of the Series A Preferred Stock as of January
    2, 1997, thereby satisfying the Series A Preferred Stock dividend criteria
    of the LTIP. Therefore, the cumulative amount of the dividend component of
    the award was deemed earned and was accrued in fiscal 1996. Amounts
    accrued under the LTIP are allocated to specified senior officers. Amounts
    in the table reflect the potential pool amounts accrued in 1996 allocable
    to each of Alliance's Named Executive Officers based upon the two criteria
    summarized above as applied to fiscal 1996.
 
  Pursuant to the terms of the LTIP, at the effective time of the
Recapitalization, Messrs. Zehner, Pino, White, Andrues and Mericle will be
paid $543,750, $435,000 and $326,250, $217,500 and $217,500, respectively
(before federal and state income taxes) earned by them pursuant to the LTIP
through the date of the Recapitalization.
 
EMPLOYMENT AND RELATED AGREEMENTS
 
  Payments Under Existing Employment Agreements. Each of the Named Executive
Officers has an employment agreement with Alliance. The Recapitalization will
constitute a "change of control" for the purposes of such employment
agreements.
 
  The employment agreements for Messrs. Andrues and Mericle provide that (i)
if Alliance takes actions which constitute Constructive Discharge (as defined
in such agreements) or terminates such executive without Just Cause (as
defined in such agreements) within one year before or one year after a change
of control or (ii) the executive quits for any reason within one year
following a change of control, then such executive shall be entitled to
receive: (x) a cash amount equal to the sum of the executive's salary at the
time of termination and the executive's target bonus for the year of
termination and (y) a continuation of benefits (including car allowance,
health insurance and 401(k) plan benefits) for a period of 12 months following
termination.
 
  The existing employment agreements for Messrs. Zehner, Pino and White were
amended on May 15, 1997 to provide that upon the occurrence of a change in
control, such executives are entitled to receive (i) a cash amount equal to
2.5 times (two times in the case of Mr. White) the sum of the executive's
salary at the time of the change of control and the executive's target bonus
for the year in which the change of control occurs, and (ii) continuation of
benefits (including car allowance, health insurance and 401(k) plan benefits)
for a period of 30 months (24 months in the case of Mr. White) following the
change of control. Prior to the May 15, 1997 amendments, such payments would
have been made, and such benefits would have been provided, only if (i)
Alliance were to take actions which constitute constructive discharge (as
defined in such agreements) or to terminate such executive without just cause
(as defined in such agreements) within one year before or one year after the
change of control, or (ii) the executive were to quit for any reason within
one year following a change of control.
 
                                      49
<PAGE>
 
  Each of the employment agreements discussed above prohibit the provision of
payments and benefits to the extent such payments or benefits would cause
Alliance to be unable to deduct amounts pursuant to the provisions of Section
280G of the Internal Revenue Code of 1986, which imposes a limit on certain
payments made by a corporation that are contingent upon a change of control.
As a result of such limits, it is estimated that the amount of payments that
Alliance will make to Messrs. Zehner, Pino and White as a result of the
Recapitalization pursuant to the existing employment agreements (prior to
federal and state income taxes) will be reduced to approximately $850,000,
$500,000 and $420,000, respectively.
 
  New Employment Agreements for Messrs. Zehner and Pino. Alliance has entered
into employment agreements dated as of July 23, 1997 with Richard N. Zehner to
act as Chief Executive Officer and with Vincent S. Pino to act as Chief
Operating Officer (the "New Employment Agreements"). Base compensation under
the New Employment Agreements is $315,000 per year for Mr. Zehner and $275,000
per year for Mr. Pino, subject in each case to increase by the Board of
Directors. In addition, Mr. Zehner and Mr. Pino are entitled to receive an
annual cash bonus based upon Alliance's achievement of certain operating
and/or financial goals, with an annual target bonus amount equal to a
specified percentage of their then current annual base salary (75% in the case
of Mr. Zehner and 60% in the case of Mr. Pino). In connection with the New
Employment Agreements, Mr. Zehner and Mr. Pino are entitled to receive 145,000
and 130,000 options, respectively, under the New Stock Option Plan.
 
  The term of each New Employment Agreement is initially three years. After
the first year, the New Employment Agreements will have a term of two years,
with automatic extensions for additional three month periods if neither party
gives notice that the term will not be so extended. Alliance may terminate Mr.
Zehner's or Mr. Pino's employment at any time and for any reason and Mr.
Zehner and Mr. Pino may resign at any time and for any reason.
 
  Agreements Not to Compete. Mr. Zehner and Mr. Pino have also entered into an
agreement not to compete with Alliance. Pursuant to such agreement, Mr. Zehner
and Mr. Pino have each agreed that they will not, prior to the later of five
years following the Recapitalization and two years after the date of their
termination, (i) engage in any Competitive Business in the United States or
(ii) compete or participate as an agent, consultant, advisor, representative,
owner, investor or otherwise in any enterprise engaged in a Competitive
Business in the United States. Ownership of less than 5% of a publicly-traded
entity engaged in a Competitive Business would not be a violation of the
covenant to compete. For these purposes, "Competitive Business" means any
imaging business or other business that becomes material to Alliance during
the term of Mr. Zehner's or Mr. Pino's employment.
 
  In addition, prior to 24 months after the later of the date of his
termination or the date of ceasing to receive payments under the agreement not
to compete, Mr. Zehner and Mr. Pino, as the case may be, have each agreed not
to make any contact with any customer of Alliance with respect to the
provision of any service that is the same or substantially similar to any
service provided to such customer by Alliance. Furthermore, prior to 12 months
after the later of the date of their respective terminations of employment or
the date of ceasing to receive payments under the agreements not to compete,
Mr. Zehner and Mr. Pino, as the case may be, have each agreed not to solicit
or make any contact with any employee of Alliance with respect to any
employment, service or other business relationship. In consideration of the
non-competition and non-solicitation agreements of Mr. Zehner and Mr. Pino,
Alliance has agreed to make certain payments to Mr. Zehner and Mr. Pino
following the termination of their employment. However, in the event of a
termination with cause or a resignation without good reason (as defined in the
New Employment Agreements), Alliance will be under no obligation to make such
payments.

following consummation of the Transactions, through a combination of (i) the
rollover of existing options to purchase shares of Company Common Stock and
(ii) the issuance of options pursuant to the Company's New Option Plan,
management will own in excess of 11% of the shares of Company Common Stock on
a fully diluted basis.

of $400,000, which was earned upon the initial submission of Salomon's
fairness opinion to the Board of Directors on July 22, 1997; plus (c) an
additional fee of $2.4 million, which is contingent upon the consummation of
the Recapitalization and payable at the closing thereof. In addition, Salomon

                      DESCRIPTION OF THE CREDIT AGREEMENT
 
CREDIT AGREEMENT
 
  General. Pursuant to a commitment letter dated as of November 10, 1997 from
Bankers Trust Company (the "Agent") to Apollo (the "Commitment Letter") and
subject to the negotiation, execution and delivery of definitive
documentation, the Agent has committed to lend to the Company (the "Loans"),
$50 million in the form of the Term Loan Facility and up to $75 million in the
form of the Revolving Loan Facility for an aggregate principal amount of up to
$125 million (the "Commitment").
 
  Pursuant to the Commitment Letter, the Agent reserves the right to syndicate
all or a portion of the Commitment to one or more financial institutions
(including the Agent, each, a "Lender"), such institutions being subject to
the Company's approval. Upon the acceptance of the commitment of any Lender to
provide a portion of the Commitment, the Agent will be released from that
portion of the Commitment. In addition, the Agent agrees to serve as
administrative and syndication agent in connection with the Loans, as well as
fronting bank in connection with the letters of credit issued under the
Revolving Loan Facility.
 
  The following terms and descriptions of the Loans are based upon the terms
set forth in the Commitment Letter and are subject to the final negotiation
and execution of the Credit Agreement and related documents. As a result, the
final terms of the Loans may vary from those set forth below.
 
  Use of Proceeds; Maturity. The Loans are expected to be made available to
the Company to finance in part the Transactions and certain related costs and
expenses, and to refinance certain existing indebtedness of Alliance. The full
amount to be borrowed under the Term Loan Facility must be drawn in a single
drawing on the date the Term Loan Facility is closed, which is expected to be
the date on which the Transactions close (the "Closing Date"). The Revolving
Loan Facility is expected to be available at the Closing Date and thereafter
to finance (including through the making of revolving loans and the issuance
of letters of credit) working capital requirements and general corporate
purposes of the Company. The Term Loan Facility matures on the sixth
anniversary of the Closing Date. The Revolving Loan Facility will mature on
the fifth anniversary of the Closing Date. The Credit Agreement will require
the Company to reduce the commitments under the Revolving Loan Facility to
$37.5 million on the fourth anniversary of the Closing Date and to make annual
amortization payments with respect to the Term Loan Facility of $0.5 million
per year in the first five years and $47.5 million in the sixth year.
 
  Prepayments. Loans are required to be prepaid with (a) 100% of the net
proceeds of all non-ordinary-course asset sales or other dispositions of the
property by the Company and its subsidiaries, subject to limited exceptions,
(b) 100% of the net proceeds of issuances of debt obligations and certain
preferred stock by the Company and its subsidiaries, subject to limited
exceptions, (c) 50% of the net proceeds from common equity and certain
preferred stock issuances by the Company and its subsidiaries, subject to
limited exceptions, (d) 75% of annual excess cash flow and (e) 100% of certain
insurance proceeds, subject to limited exceptions. Such mandatory prepayments
will be allocated as follows: first, to the Term Loan Facility and second, to
the Revolving Loan Facility.
 
  Voluntary prepayments will be permitted in whole or in part, at the option
of the Company, in minimum principal amounts to be agreed upon, without
premium or penalty, subject to reimbursement of the Lender's re-deployment
costs in the case of prepayment of Reserve Adjusted Eurodollar Loans (as
defined in the Commitment Letter) other than on the last day of the relevant
interest period.
 
  Interest and Fees. The interest rates under the Loans will be as follows:
 
  (a) Term Loan Facility: At the option of the Company, (i) 1.50% in excess of
the higher of (A) 1/2 of 1% in excess of the Federal Reserve reported
certificate of deposit rate and (B) the rate that the Agent announces from
time to time as its prime lending rate, as in effect from time to time, and
(ii) 2.50% in excess of the Reserve Adjusted Eurodollar Rate, in each case,
subject to decreases based upon the Company's leverage ratio.
 
                                      53
<PAGE>
 
  (b) Revolving Loan Facility: At the option of the Company, (i) 1.25% in
excess of the higher of (A) 1/2 of 1% in excess of the Federal Reserve
reported certificate of deposit rate and (B) the rate that the Agent announces
from time to time as its prime lending rate, as in effect from time to time,
and (ii) 2.25% in excess of the Reserve Adjusted Eurodollar Rate, in each
case, subject to decreases based upon the Company's leverage ratio.
 
  The Company may elect interest periods of 1, 2, 3 or 6 months for Reserve
Adjusted Eurodollar Loans. With respect to Reserve Adjusted Eurodollar Loans,
interest will be payable at the end of each interest period and, in any event,
at least every 3 months. With respect to Base Rate Loans (as defined in the
Commitment Letter), interest will be payable quarterly on the last business
day of each fiscal quarter. In each case, calculation of interest will be on
the basis of actual number of days elapsed in a year of 360 days.
 
  The Commitment Letter provides for payment by the Company in respect of
outstanding letters of credit of (i) a per annum fee equal to the spread over
the Reserve Adjusted Eurodollar Rate for the Revolving Loan Facility from time
to time in effect, (ii) a fronting fee equal to 1/4 of 1% on the aggregate
outstanding stated amounts of such letters of credit, plus (iii) customary
administrative charges. The Company will also pay a commitment fee equal to
1/2 of 1% per annum on the undrawn portion of the available Commitment,
subject to decreases based on the Company's leverage ratio.
 
  Collateral and Guarantees. The Loans will be guaranteed by all of the
Company's existing and future direct and indirect wholly owned domestic
subsidiaries. The Loans will be secured by a first priority lien in
substantially all of the properties and assets of the Company and its direct
and indirect wholly owned domestic subsidiaries, now owned or acquired later,
including a pledge of all capital stock and notes owned by the Company and its
subsidiaries; provided that, in certain cases, no more than 65% of the stock
of foreign subsidiaries of the Company shall be required to be pledged.
 
  Representations and Warranties and Covenants. The Commitment Letter provides
that the Credit Agreement documentation will contain certain customary
representations and warranties by the Company. In addition, the Credit
Agreement is expected to contain customary covenants restricting the ability
of the Company to, among others (i) declare dividends or redeem or repurchase
capital stock; (ii) prepay, redeem or purchase debt; (iii) incur liens and
engage in sale-leaseback transactions; (iv) make loans and investments; (v)
incur additional indebtedness; (vi) amend or otherwise alter debt and other
material agreements; (vii) make capital expenditures; (viii) engage in
mergers, acquisitions and asset sales; (ix) transact with affiliates; and (x)
alter the business it conducts. It is also expected that the Company will be
required to indemnify the Agent and comply with specified financial covenants
and make certain customary affirmative covenants.
 
  Events of Default. Events of default under the Credit Agreement are expected
to include (i) the Company's failure to pay principal or interest when due;
(ii) the Company's material breach of any representation or warranty contained
in the loan documents; (iii) covenant defaults; (iv) events of bankruptcy; and
(v) a change of control of the Company.

<PAGE>
 
                           DESCRIPTION OF THE NOTES
   
  The Notes will be issued under an indenture (the "Indenture"), to be dated
as of      , 1997 by and among Alliance Imaging, Inc., the Guarantors and IBJ
Schroder Bank & Trust Company, as Trustee (the "Trustee"). The following
summary of certain provisions of the Indenture does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, the Trust
Indenture Act of 1939, as amended (the "TIA"), and to all of the provisions of
the Indenture (a copy of which has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part), including the
definitions of certain terms therein and those terms made a part of the
Indenture by reference to the TIA as in effect on the date of the Indenture.
The definitions of certain capitalized terms used in the following summary are
set forth below under "--Certain Definitions." For purposes of this section,
references to the "Company" include only Alliance Imaging, Inc. and not its
Subsidiaries.     
 
  The Notes will be unsecured obligations of the Company, ranking subordinate
in right of payment to all Senior Debt of the Company.
 
  The Notes will be issued in fully registered form only, without coupons, in
denominations of $1,000 and integral multiples thereof. Initially, the Trustee
will act as Paying Agent and Registrar for the Notes. The Notes may be
presented for registration or transfer and exchange at the offices of the
Registrar, which initially will be the Trustee's corporate trust office. The
Company may change any Paying Agent and Registrar without notice to holders of
the Notes (the "Holders"). The Company will pay principal (and premium, if
any) on the Notes at the Trustee's corporate office in New York, New York. At
the Company's option, interest may be paid at the Trustee's corporate trust
office or by check mailed to the registered address of Holders.
 
PRINCIPAL, MATURITY AND INTEREST
   
  The Notes are limited in aggregate principal amount to $265.0 million,
$125.0 million of which will be issued in the Offering as Fixed Rate Notes and
$40.0 million of which will be issued in the Offering as Floating Rate Notes,
and all of which will mature on      , 2005. Interest on the Notes will be
payable semi-annually in cash on each      and      (each an "Interest Payment
Date") commencing on      , 1998, for the period commencing on and including
the immediately preceding Interest Payment Date and ending on and including
the day next preceding the Interest Payment Date (an "Interest Period"), with
the exception that the first Interest Period will commence on and include
December  , 1997 and end on and include       , 1998. Interest is payable to
the persons who are registered Holders at the close of business on the
and        immediately preceding the applicable Interest Payment Date.     
 
  The Notes will not be entitled to the benefit of any mandatory sinking fund.
   
 Fixed Rate Notes     
   
  Interest on the Fixed Rate Notes will accrue at the rate of   % per annum.
       
 Floating Rate Notes     
   
  The Floating Rate Notes will bear interest at a rate per annum, reset semi-
annually, equal to LIBOR (as defined) plus   %, as determined by the
Calculation Agent (the "Calculation Agent"), which shall initially be the
Trustee.     
   
  "LIBOR", with respect to an Interest Period, will be the rate (expressed as
a percentage per annum) for deposits in United States dollars for a six-month
period beginning on the second London Banking Day (as defined) after the
Determination Date (as defined) that appears on Telerate Page 3750 (as
defined) as of 11:00 a.m., London time, on the Determination Date. If Telerate
Page 3750 does not include such a rate or is unavailable on a Determination
Date, LIBOR for the Interest Period shall be the arithmetic mean of the rates
(expressed as a percentage per annum) for deposits in a Representative Amount
(as defined) in United States     
 
                                      55

dollars for a six-month period beginning on the second London Banking Day
after the Determination Date that appears on Reuters Screen LIBO Page (as
defined) as of 11:00 a.m., London time, on the Determination Date. If Reuters
Screen LIBO Page does not include two or more rates or is unavailable on a
Determination Date, the Calculation Agent will request the principal London
office of each of four major banks in the London interbank market, as selected
by the Calculation Agent, to provide such bank's offered quotation (expressed
as a percentage per annum), as of approximately 11:00 a.m., London time, on
such Determination Date, to prime banks in the London interbank market for
deposits in a Representative Amount in United States dollars for a six-month
period beginning on the second London Banking Day after the Determination
Date. If at least two such offered quotations are so provided, LIBOR for the
Interest Period will be the arithmetic mean of such quotations. If fewer than
two such quotations are so provided, the Calculation Agent will request each
of three major banks in New York City, as selected by the Calculation Agent,
to provide such bank's rate (expressed as a percentage per annum), as of
approximately 11:00 a.m., New York City time, on such Determination Date, for
loans in a Representative Amount in United States dollars to leading European
banks for a six-month period beginning on the second London Banking Day after
the Determination Date. If at least two such rates are so provided, LIBOR for
the Interest Period will be the arithmetic mean of such rates. If fewer than
two such rates are so provided, then LIBOR for the Interest Period will be
LIBOR in effect with respect to the immediately preceding Interest Period.
       
  "Determination Date," with respect to an Interest Period, will be the second
London Banking Day preceding the first day of the Interest Period.     
   
  "London Banking Day" is any day in which dealings in United States dollars
are transacted or, with respect to any future date, are expected to be
transacted in the London interbank market.     
   
  "Representative Amount" means a principal amount of not less than U.S.
$1,000,000 for a single transaction in the relevant market at the relevant
time.     
   
  "Telerate Page 3750" means the display designated as "Page 3750" on the Dow
Jones Telerate Service (or such other page as may replace Page 3750 on that
service).     
   
  "Reuters Screen LIBO Page" means the display designated as page "LIBO" on
The Reuters Monitor Money Rates Service (or such other page as may replace the
LIBO page on that service).     
   
  The amount of interest for each day that the Floating Rate Notes are
outstanding (the "Daily Interest Amount") will be calculated by dividing the
interest rate in effect for such day by 360 and multiplying the result by the
principal amount of the Floating Rate Notes. The amount of interest to be paid
on the Floating Rate Notes for each Interest Period will be calculated by
adding the Daily Interest Amounts for each day in the Interest Period.     
   
  All percentages resulting from any of the above calculations will be
rounded, if necessary, to the nearest one hundred-thousandth of a percentage
point, with five one-millionths of a percentage point rounded upwards (e.g.,
9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all
dollar amounts used in or resulting from such calculations will be rounded to
the nearest cent (with one-half cent being rounded upwards).     
   
  The interest rate on the Floating Rate Notes will in no event be higher than
the maximum rate permitted by New York law as the same may be modified by
United States law of general application. Under current New York law, the
maximum rate of interest is 25% per annum on a simple interest basis. This
limit may not apply to Floating Rate Notes in which $2,500,000 or more has
been invested.     
   
  The Calculation Agent will, upon the request of the holder of any Floating
Rate Note, provide the interest rate then in effect with respect to the
Floating Rate Notes. All calculations made by the Calculation Agent in the
absence of manifest error will be conclusive for all purposes and binding on
the Company and the Holders of the Floating Rate Notes.

  Optional Redemption of Fixed Rate Notes upon Equity Offerings. At any time,
or from time to time, on or prior to       , 2000, the Company may, at its
option, use the net cash proceeds of one or more Equity Offerings (as defined
below) to redeem up to 40% in aggregate principal amount of the Fixed Rate
Notes at a redemption price equal to  % of the principal amount thereof plus
accrued and unpaid interest thereon, if any, to the date of redemption;
provided, however, that after any such redemption the aggregate principal
amount of the Fixed Rate Notes outstanding must equal at least 60% of the
aggregate amount of the Fixed Rate Notes issued in the Offering plus any
additional Fixed Rate Notes issued after the Issue Date pursuant to the
Indenture. In order to effect the foregoing redemption with the net cash
proceeds of any Equity Offering, the Company shall make such redemption not
more than 120 days after the consummation of any such Equity Offering.     
 
  As used in the preceding paragraph, "Equity Offering" means a public or
private offering of Qualified Capital Stock (other than public offerings with
respect to the Company's Common Stock on Form S-8) of the Company for
aggregate net cash proceeds to the Company of at least $25.0 million.
 
SELECTION AND NOTICE OF REDEMPTION
   
  In the event that less than all of the Notes are to be redeemed at any time,
selection of such Notes for redemption will be made by the Trustee in
compliance with the requirements of the principal national securities
exchange, if any, on which such Notes are listed or, if such Notes are not
then listed on a national securities exchange, on a pro rata basis, by lot or
by such method as the Trustee shall deem fair and appropriate; provided,
however, that no Notes of a principal amount of $1,000 or less shall be
redeemed in part; provided, further, that if a partial redemption is made with
the net cash proceeds of an Equity Offering, selection of the Fixed Rate Notes
or portions thereof for redemption shall be made by the Trustee only on a pro
rata basis or on as nearly a pro rata basis as is practicable (subject to DTC
procedures), unless such method is otherwise prohibited. Notice of redemption
shall be mailed by first-class mail at least 30 but not more than 60 days
before the redemption     
 
                                      57
<PAGE>
 
date to each Holder of Notes to be redeemed at its registered address. If any
Note is to be redeemed in part only, the notice of redemption that relates to
such Note shall state the portion of the principal amount thereof to be
redeemed. A new Note in a principal amount equal to the unredeemed portion
thereof will be issued in the name of the Holder thereof upon cancellation of
the original Note. On and after the redemption date, interest will cease to
accrue on Notes or portions thereof called for redemption as long as the
Company has deposited with the Paying Agent funds in satisfaction of the
applicable redemption price pursuant to the Indenture.
 
SUBORDINATION
 
  The payment of all Obligations on the Notes is subordinated in right of
payment to the prior payment in full in cash or Cash Equivalents of all
Obligations on Senior Debt. Upon any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or securities, to
creditors upon any liquidation, dissolution, winding up, reorganization,
assignment for the benefit of creditors or marshaling of assets of the Company
or in a bankruptcy, reorganization, insolvency, receivership or other similar
proceeding relating to the Company or its property, whether voluntary or
involuntary, all Obligations due or to become due upon all Senior Debt shall
first be paid in full in cash or Cash Equivalents, or such payment duly
provided for to the satisfaction of the holders of Senior Debt, before any
payment or distribution of any kind or character is made on account of any
Obligations on the Notes, or for the acquisition of any of the Notes for cash
or property or otherwise. If any default occurs and is continuing in the
payment when due, whether at maturity, upon any redemption, by declaration or
otherwise, of any principal of, interest on, unpaid drawings for letters of
credit issued in respect of, or regularly accruing fees with respect to, any
Senior Debt, no payment of any kind or character shall be made by or on behalf
of the Company or any other Person on its or their behalf with respect to any
Obligations on the Notes or to acquire any of the Notes for cash or property
or otherwise.
 
  In addition, if any other event of default occurs and is continuing with
respect to any Designated Senior Debt, as such event of default is defined in
the instrument creating or evidencing such Designated Senior Debt, permitting
the holders of such Designated Senior Debt then outstanding to accelerate the
maturity thereof and if the Representative for the respective issue of
Designated Senior Debt gives written notice of the event of default to the
Trustee (a "Default Notice"), then, unless and until all events of default
have been cured or waived or have ceased to exist or the Trustee receives
notice from the Representative for the respective issue of Designated Senior
Debt terminating the Blockage Period (as defined below), during the 180 days
after the delivery of such Default Notice (the "Blockage Period"), neither the
Company nor any other Person on its behalf shall (x) make any payment of any
kind or character with respect to any Obligations on the Notes or (y) acquire
any of the Notes for cash or property or otherwise. Notwithstanding anything
herein to the contrary, in no event will a Blockage Period extend beyond 180
days from the date the payment on the Notes was due and only one such Blockage
Period may be commenced within any 360 consecutive days. No event of default
which existed or was continuing on the date of the commencement of any
Blockage Period with respect to the Designated Senior Debt shall be, or be
made, the basis for commencement of a second Blockage Period by the
Representative of such Designated Senior Debt whether or not within a period
of 360 consecutive days, unless such event of default shall have been cured or
waived for a period of not less than 90 consecutive days (it being
acknowledged that any subsequent action, or any breach of any financial
covenants for a period commencing after the date of commencement of such
Blockage Period that, in either case, would give rise to an event of default
pursuant to any provisions under which an event of default previously existed
or was continuing shall constitute a new event of default for this purpose).
 
  By reason of such subordination, in the event of the insolvency of the
Company, creditors of the Company who are not holders of Senior Debt,
including the Holders of the Notes, may recover less, ratably, than holders of
Senior Debt.
 
  After giving effect to the Transactions, on a pro forma basis, at September
30, 1997, the Company would have had approximately $56.9 million of Senior
Debt outstanding.
 
 
                                      58

GUARANTEES
 
  Each Guarantor unconditionally guarantees, on a senior subordinated basis,
jointly and severally, to each Holder and the Trustee, the full and prompt
performance of the Company's obligations under the Indenture and the Notes,
including the payment of principal of and interest on the Notes. The
Guarantees will be subordinated to Guarantor Senior Debt on the same basis as
the Notes are subordinated to Senior Debt. The obligations of each Guarantor
are limited to the maximum amount which, after giving effect to all other
contingent and fixed liabilities of such Guarantor and after giving effect to
any collections from or payments made by or on behalf of any other Guarantor
in respect of the obligations of such other Guarantor under its Guarantee or
pursuant to its contribution obligations under the Indenture, will result in
the obligations of such Guarantor under the Guarantee not constituting a
fraudulent conveyance or fraudulent transfer under federal or state law. Each
Guarantor that makes a payment or distribution under a Guarantee shall be
entitled to a contribution from each other Guarantor in an amount pro rata,
based on the net assets of each Guarantor, determined in accordance with GAAP.
 
  Each Guarantor may consolidate with or merge into or sell its assets to the
Company or another Guarantor that is a Wholly Owned Restricted Subsidiary of
the Company without limitation, or with other Persons upon the terms and
conditions set forth in the Indenture. See "Certain Covenants--Merger,
Consolidation and Sale of Assets." In the event all of the Capital Stock of a
Guarantor is sold by the Company and the sale complies with the provisions set
forth in "Certain Covenants--Limitation on Asset Sales," the Guarantor's
Guarantee will be released.
 
  Separate financial statements of the Guarantors are not included herein
because such Guarantors are jointly and severally liable with respect to the
Company's obligations pursuant to the Notes, and the aggregate net assets,
earnings and equity of the Guarantors and the Company are substantially
equivalent to the net assets, earnings and equity of the Company on a
consolidated basis. Accordingly, management has determined that separate
financial statements of each Guarantor would not provide any material
information to prospective purchasers of the Notes.
 
CHANGE OF CONTROL
 
  The Indenture will provide that upon the occurrence of a Change of Control,
each Holder will have the right to require that the Company purchase all or a
portion of such Holder's Notes pursuant to the offer described below (the
"Change of Control Offer"), at a purchase price equal to 101% of the principal
amount thereof plus accrued interest to the date of purchase.
 
  The Indenture will provide that, prior to the mailing of the notice referred
to below, but in any event within 30 days following any Change of Control, the
Company covenants to (i) repay in full and terminate all commitments under
Indebtedness under the Credit Agreement and all other Senior Debt the terms of
which require repayment upon a Change of Control or offer to repay in full and
terminate all commitments under all Indebtedness under the Credit Agreement
and all other such Senior Debt and to repay the Indebtedness owed to each
lender which has accepted such offer or (ii) obtain the requisite consents
under the Credit Agreement and all other Senior Debt to permit the repurchase
of the Notes as provided below. The Company shall first comply with the
covenant in the immediately preceding sentence before it shall be required to
repurchase Notes pursuant to the provisions described below. The Company's
failure to comply with the covenant described in the immediately preceding
sentence shall constitute an Event of Default described in clause (iii) and
not in clause (ii) under "Events of Default" below.
 
  Within 30 days following the date upon which the Change of Control occurred,
the Company must send, by first class mail, a notice to each Holder, with a
copy to the Trustee, which notice shall govern the terms of the Change of
Control Offer. Such notice shall state, among other things, the purchase date,
which must be no earlier than 30 days nor later than 45 days from the date
such notice is mailed, other than as may be required by law (the "Change of
Control Payment Date"). Holders electing to have a Note purchased pursuant to
a Change of Control Offer will be required to surrender the Note, with the
form entitled "Option of Holder to Elect
 
                                      59
<PAGE>
 
Purchase" on the reverse of the Note completed, to the Paying Agent at the
address specified in the notice prior to the close of business on the third
business day prior to the Change of Control Payment Date.
 
  If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
purchase price for all the Notes that might be delivered by Holders seeking to
accept the Change of Control Offer. In the event the Company is required to
purchase outstanding Notes pursuant to a Change of Control Offer, the Company
expects that it would seek third party financing to the extent it does not
have available funds to meet its purchase obligations. However, there can be
no assurance that the Company would be able to obtain such financing.
 
  Neither the Board of Directors of the Company nor the Trustee may waive the
covenant relating to a Holder's right to redemption upon a Change of Control.
Restrictions in the Indenture described herein on the ability of the Company
and its Restricted Subsidiaries to incur additional Indebtedness, to grant
liens on its property, to make Restricted Payments and to make Asset Sales may
also make more difficult or discourage a takeover of the Company, whether
favored or opposed by the management of the Company. Consummation of any such
transaction in certain circumstances may require redemption or repurchase of
the Notes, and there can be no assurance that the Company or the acquiring
party will have sufficient financial resources to effect such redemption or
repurchase. Such restrictions and the restrictions on transactions with
Affiliates may, in certain circumstances, make more difficult or discourage
any leveraged buyout of the Company or any of its Restricted Subsidiaries by
the management of the Company. While such restrictions cover a wide variety of
arrangements which have traditionally been used to effect highly leveraged
transactions, the Indenture may not afford the Holders of Notes protection in
all circumstances from the adverse aspects of a highly leveraged transaction,
reorganization, restructuring, merger or similar transaction.
 
  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Change of Control Offer. To the extent that
the provisions of any securities laws or regulations conflict with the "Change
of Control" provisions of the Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the "Change of Control" provisions of the
Indenture by virtue thereof.
 
  The definition of "Change of Control" includes, among other transactions, a
disposition of all or substantially all of the property and assets of the
Company. With respect to the disposition of property or assets, the phrase
"all or substantially all" as used in the Indenture varies according to the
facts and circumstances of the subject transaction, has no clearly established
meaning under New York law (which is the choice of law under the Indenture)
and is subject to judicial interpretation. Accordingly, in certain
circumstances, there may be a degree of uncertainty in ascertaining whether a
particular transaction would involve a disposition of "all or substantially
all" of the property or assets of a Person, and therefore it may be unclear
whether a Change of Control has occurred and whether the Company is required
to make an offer to repurchase the Notes as described above.
 
CERTAIN COVENANTS
 
  The Indenture will contain, among others, the following covenants:
 
  Limitation on Incurrence of Additional Indebtedness. The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume, guarantee, acquire, become liable,
contingently or otherwise, with respect to, or otherwise become responsible
for payment of (collectively, "incur") any Indebtedness (other than Permitted
Indebtedness); provided, however, that if no Default or Event of Default shall
have occurred and be continuing at the time of or as a consequence of the
incurrence of any such Indebtedness, the Company or any of the Guarantors may
incur Indebtedness (including, without limitation, Acquired Indebtedness) and
Restricted Subsidiaries of the Company may incur Acquired Indebtedness, in
each case if on the date of the incurrence of such Indebtedness, after giving
effect to the incurrence thereof, the
 
                                      60
<PAGE>
 
Consolidated Fixed Charge Coverage Ratio of the Company is greater than 1.75
to 1.0 if such incurrence is on or prior to December 31, 1999 and 2.0 to 1.0
if such incurrence is thereafter.
 
  Limitation on Restricted Payments. The Company will not, and will not cause
or permit any of its Restricted Subsidiaries to, directly or indirectly, (a)
declare or pay any dividend or make any distribution (other than dividends or
distributions payable in Qualified Capital Stock of the Company) on or in
respect of shares of the Company's Capital Stock to holders of such Capital
Stock, (b) purchase, redeem or otherwise acquire or retire for value any
Capital Stock of the Company or any warrants, rights or options to purchase or
acquire shares of any class of such Capital Stock, (c) make any principal
payment on, purchase, defease, redeem, prepay, decrease or otherwise acquire
or retire for value, prior to any scheduled final maturity, scheduled
repayment or scheduled sinking fund payment, any Indebtedness of the Company
that is subordinate or junior in right of payment to the Notes or (d) make any
Investment (other than Permitted Investments) (each of the foregoing actions
set forth in clauses (a), (b), (c) and (d) being referred to as a "Restricted
Payment"), if at the time of such Restricted Payment or immediately after
giving effect thereto, (i) a Default or an Event of Default shall have
occurred and be continuing or (ii) the Company is not able to incur at least
$1.00 of additional Indebtedness (other than Permitted Indebtedness) in
compliance with the "Limitation on Incurrence of Additional Indebtedness"
covenant or (iii) the aggregate amount of Restricted Payments (including such
proposed Restricted Payment) made subsequent to the Issue Date (the amount
expended for such purposes, if other than in cash, being the fair market value
of such property as determined reasonably and in good faith by the Board of
Directors of the Company) shall exceed the sum of: (w) 50% of the cumulative
Consolidated Net Income (or if cumulative Consolidated Net Income shall be a
loss, minus 100% of such loss) of the Company earned subsequent to the Issue
Date and on or prior to the date the Restricted Payment occurs (the "Reference
Date") (treating such period as a single accounting period); plus (x) 100% of
the aggregate net cash proceeds received by the Company from any Person (other
than a Subsidiary of the Company) from the issuance and sale subsequent to the
Issue Date and on or prior to the Reference Date of Qualified Capital Stock of
the Company; plus (y) without duplication of any amounts included in clause
(iii)(x) above, 100% of the aggregate net cash proceeds of any equity
contribution received by the Company from a holder of the Company's Capital
Stock; plus (z) without duplication, the sum of (1) the aggregate amount
returned in cash on or with respect to Investments (other than Permitted
Investments) made subsequent to the Issue Date whether through interest
payments, principal payments, dividends or other distributions or payments,
(2) the net cash proceeds received by the Company or any Restricted Subsidiary
of the Company from the disposition of all or any portion of such Investments
(other than to a Subsidiary of the Company) and (3) upon redesignation of an
Unrestricted Subsidiary as a Restricted Subsidiary, the fair market value of
such Subsidiary; provided, however, that the sum of clauses (1), (2) and (3)
above shall not exceed the aggregate amount of all such Investments made
subsequent to the Issue Date.
 
  Notwithstanding the foregoing, the provisions set forth in the immediately
preceding paragraph do not prohibit: (1) the payment of any dividend within 60
days after the date of declaration of such dividend if the dividend would have
been permitted on the date of declaration; (2) if no Default or Event of
Default shall have occurred and be continuing, the acquisition of any shares
of Capital Stock of the Company, either (i) solely in exchange for shares of
Qualified Capital Stock of the Company or (ii) through the application of net
proceeds of a substantially concurrent sale for cash (other than to a
Subsidiary of the Company) of shares of Qualified Capital Stock of the
Company; (3) if no Default or Event of Default shall have occurred and be
continuing, the acquisition of any Indebtedness of the Company that is
subordinate or junior in right of payment to the Notes either (i) solely in
exchange for shares of Qualified Capital Stock of the Company, or (ii) through
the application of net proceeds of a substantially concurrent sale for cash
(other than to a Subsidiary of the Company) of (A) shares of Qualified Capital
Stock of the Company or (B) Refinancing Indebtedness; (4) so long as no
Default or Event of Default shall have occurred and be continuing, repurchases
by the Company of Common Stock of the Company from employees of the Company or
any of its Subsidiaries or their authorized representatives upon the death,
disability or termination of employment of such employees, in an amount not to
exceed $5.0 million in any calendar year or $15.0 million in the aggregate;
(5) so long as no Default or Event of Default shall have occurred or be
continuing, the declaration and payment of dividends to holders of any class
or series of Preferred
 
                                      61
<PAGE>
 
Stock (other than Disqualified Capital Stock) issued after the Issue Date,
provided that after giving effect to such issuance on a pro forma basis, the
Company would have had a Consolidated Fixed Charge Coverage Ratio of at least
1.75 to 1.00; (6) the payment of dividends on the Company's Common Stock,
following the first public offering of the Company's Common Stock after the
Issue Date, of up to 6% per annum of the net proceeds received by the Company
in such public offering, other than public offerings with respect to the
Company's Common Stock registered on Form S-8; (7) the repurchase, retirement
or other acquisition or retirement for value of equity interests of the
Company in existence on the Issue Date and from the persons holding such
equity interests on the Issue Date and which are not held by Apollo or any of
its Affiliates or members of management of the Company and its Subsidiaries on
the Issue Date (including any equity interests issued in respect of such
equity interests as a result of a stock split, recapitalization, merger,
combination, consolidation or similar transaction), provided, however, that
the Company shall be permitted to make Restricted Payments under this clause
only if after giving effect thereto, the Company would be permitted to incur
at least $1.00 of additional Indebtedness (other than Permitted Indebtedness)
pursuant to the "Limitation on Incurrence of Additional Indebtedness"
covenant; (8) so long as no Default or Event of Default shall have occurred
and be continuing, the repurchase, retirement or other acquisition or
retirement for value of the Company's Series F Preferred Stock, provided that
after giving effect to such repurchase, retirement or other acquisition or
retirement for value on a pro forma basis, the Company would have had a
Consolidated Fixed Charge Coverage Ratio of at least 2.5 to 1.0; and (9) other
Restricted Payments in an aggregate amount not to exceed $5.0 million. In
determining the aggregate amount of Restricted Payments made subsequent to the
Issue Date in accordance with clause (iii) of the immediately preceding
paragraph, amounts expended pursuant to clauses (1), (2), (4), (5), (6), (7),
(8) and (9) shall be included in such calculation.
 
  Not later than the date of making any Restricted Payment, the Company shall
deliver to the Trustee an officers' certificate stating that such Restricted
Payment complies with the Indenture and setting forth in reasonable detail the
basis upon which the required calculations were computed, which calculations
may be based upon the Company's latest available internal quarterly financial
statements.
 
  Limitation on Asset Sales. The Company will not, and will not permit any of
its Restricted Subsidiaries to, consummate an Asset Sale unless (i) the
Company or the applicable Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Sale at least equal to the fair market
value of the assets sold or otherwise disposed of (as determined in good faith
by the Company's Board of Directors), (ii) at least 75% of the consideration
received by the Company or the Restricted Subsidiary, as the case may be, from
such Asset Sale shall be in the form of cash or Cash Equivalents and is
received at the time of such disposition; provided that the amount of (a) any
liabilities (as shown on the Company's or such Restricted Subsidiary's most
recent balance sheet) of the Company or any Restricted Subsidiary (other than
liabilities that are by their terms subordinated to the Notes) that are
assumed by the transferee of any such assets, and (b) any notes or other
obligations received by the Company or any such Restricted Subsidiary from
such transferee that are converted by the Company or such Restricted
Subsidiary into cash within 180 days after such Asset Sale (to the extent of
the cash received) shall be deemed to be cash for the purposes of this
provision; and (iii) upon the consummation of an Asset Sale, the Company shall
apply, or cause such Restricted Subsidiary to apply, the Net Cash Proceeds
relating to such Asset Sale within 360 days of receipt thereof either (A) to
prepay any Senior Debt or Guarantor Senior Debt and, in the case of any Senior
Debt or Guarantor Senior Debt under any revolving credit facility, effect a
permanent reduction in the availability under such revolving credit facility,
(B) to make an Investment in properties and assets that replace the properties
and assets that were the subject of such Asset Sale or in properties and
assets that will be used in the business of the Company and its Restricted
Subsidiaries as existing on the Issue Date or in businesses the same, similar
or reasonably related thereto ("Replacement Assets"), or (C) a combination of
prepayment and investment permitted by the foregoing clauses (iii)(A) and
(iii)(B). On the 361st day after an Asset Sale or such earlier date, if any,
as the Board of Directors of the Company or of such Restricted Subsidiary
determines not to apply the Net Cash Proceeds relating to such Asset Sale as
set forth in clauses (iii)(A), (iii)(B) and (iii)(C) of the next preceding
sentence (each, a "Net Proceeds Offer Trigger Date"), such aggregate amount of
Net Cash Proceeds which have not been applied on or before such Net Proceeds
Offer Trigger Date as permitted in clauses (iii)(A), (iii)(B) and (iii)(C) of
the next preceding sentence (each a "Net
 
                                      62
<PAGE>
 
Proceeds Offer Amount") shall be applied by the Company or such Restricted
Subsidiary to make an offer to purchase (the "Net Proceeds Offer") on a date
(the "Net Proceeds Offer Payment Date") not less than 30 nor more than 45 days
following the applicable Net Proceeds Offer Trigger Date, from all Holders on
a pro rata basis, that amount of Notes equal to the Net Proceeds Offer Amount
at a price equal to 100% of the principal amount of the Notes to be purchased,
plus accrued and unpaid interest thereon, if any, to the date of purchase;
provided, however, that if at any time any non-cash consideration received by
the Company or any Restricted Subsidiary of the Company, as the case may be,
in connection with any Asset Sale is converted into or sold or otherwise
disposed of for cash (other than interest received with respect to any such
non-cash consideration), then such conversion or disposition shall be deemed
to constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall
be applied in accordance with this covenant. The Company may defer the Net
Proceeds Offer until there is an aggregate unutilized Net Proceeds Offer
Amount equal to or in excess of $5.0 million resulting from one or more Asset
Sales (at which time, the entire unutilized Net Proceeds Offer Amount, and not
just the amount in excess of $5.0 million, shall be applied as required
pursuant to this paragraph).
 
  In the event of the transfer of substantially all (but not all) of the
property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under "--Merger, Consolidation
and Sale of Assets," the successor corporation shall be deemed to have sold
the properties and assets of the Company and its Restricted Subsidiaries not
so transferred for purposes of this covenant, and shall comply with the
provisions of this covenant with respect to such deemed sale as if it were an
Asset Sale. In addition, the fair market value of such properties and assets
of the Company or its Restricted Subsidiaries deemed to be sold shall be
deemed to be Net Cash Proceeds for purposes of this covenant.
 
  Each Net Proceeds Offer will be mailed to the record Holders as shown on the
register of Holders within 25 days following the Net Proceeds Offer Trigger
Date, with a copy to the Trustee, and shall comply with the procedures set
forth in the Indenture. Upon receiving notice of the Net Proceeds Offer,
Holders may elect to tender their Notes in whole or in part in integral
multiples of $1,000 in exchange for cash. To the extent Holders properly
tender Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of
tendering Holders will be purchased on a pro rata basis (based on amounts
tendered). A Net Proceeds Offer shall remain open for a period of 20 business
days or such longer period as may be required by law.
 
  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the
provisions of any securities laws or regulations conflict with the "Asset
Sale" provisions of the Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the "Asset Sale" provisions of the Indenture by
virtue thereof.
 
  Limitation on Dividend and Other Payment Restrictions Affecting
Subsidiaries. The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause
or permit to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary of the Company to (a) pay dividends or
make any other distributions on or in respect of its Capital Stock; (b) make
loans or advances or to pay any Indebtedness or other obligation owed to the
Company or any other Restricted Subsidiary of the Company; or (c) transfer any
of its property or assets to the Company or any other Restricted Subsidiary of
the Company, except for such encumbrances or restrictions existing under or by
reason of: (1) applicable law; (2) the Indenture; (3) the Credit Agreement;
(4) customary non-assignment provisions of any contract or any lease governing
a leasehold interest of any Restricted Subsidiary of the Company; (5) any
instrument governing Acquired Indebtedness, which encumbrance or restriction
is not applicable to any Person, or the properties or assets of any Person,
other than the Person or the properties or assets of the Person so acquired;
(6) agreements existing on the Issue Date to the extent and in the manner such
agreements are in effect on the Issue Date; (7) purchase money obligations for
property acquired in the ordinary course of business that impose restrictions
of the nature discussed in clause (c) above on the property so acquired; (8)
contracts for the sale of assets, including, without limitation, customary
restrictions with respect to a Restricted Subsidiary of the Company pursuant
to an agreement that has been entered into for the sale or disposition of all
or substantially all
 
                                      63
<PAGE>
 
of the Capital Stock or assets of such Restricted Subsidiary; (9) secured
Indebtedness otherwise permitted to be incurred pursuant to the covenants
described under "Limitation on Incurrence of Additional Indebtedness" and
"Limitation on Liens" that limit the right of the debtor to dispose of the
assets securing such Indebtedness; (10) customary provisions in joint venture
agreements and other similar agreements entered into in the ordinary course of
business; (11) an agreement governing Indebtedness incurred to Refinance the
Indebtedness issued, assumed or incurred pursuant to an agreement referred to
in clauses (1) through (10) above; provided, however, that the provisions
relating to such encumbrance or restriction contained in any such Indebtedness
are no less favorable to the Company in any material respect as determined by
the Board of Directors of the Company in their reasonable and good faith
judgment than the provisions relating to such encumbrance or restriction
contained in agreements referred to in such clauses; or (12) an agreement
governing Indebtedness permitted to be incurred pursuant to the "Limitation on
Incurrence on Additional Indebtedness" covenant; provided that the provisions
relating to such encumbrance or restriction contained in such Indebtedness are
no less favorable to the Company in any material respect as determined by the
Board of Directors of the Company in their reasonable and good faith judgment
than the provisions contained in the Credit Agreement as in effect on the
Issue Date.
 
  Limitation on Liens. The Company will not, and will not cause or permit any
of its Restricted Subsidiaries to, directly or indirectly, create, incur,
assume or permit or suffer to exist any Liens of any kind against or upon any
property or assets of the Company or any of its Restricted Subsidiaries
whether owned on the Issue Date or acquired after the Issue Date, or any
proceeds therefrom, or assign or otherwise convey any right to receive income
or profits therefrom unless (i) in the case of Liens securing Indebtedness
that is expressly subordinate or junior in right of payment to the Notes, the
Notes are secured by a Lien on such property, assets or proceeds that is
senior in priority to such Liens and (ii) in all other cases, the Notes are
equally and ratably secured, except for (A) Liens existing as of the Issue
Date to the extent and in the manner such Liens are in effect on the Issue
Date; (B) Liens securing Senior Debt and Liens securing Guarantor Senior Debt;
(C) Liens securing the Notes and the Guarantees; (D) Liens of the Company or a
Wholly Owned Restricted Subsidiary of the Company on assets of any Restricted
Subsidiary of the Company; (E) Liens securing Refinancing Indebtedness which
is incurred to Refinance any Indebtedness which has been secured by a Lien
permitted under the Indenture and which has been incurred in accordance with
the provisions of the Indenture; provided, however, that such Liens (A) are no
less favorable to the Holders and are not more favorable to the lienholders
with respect to such Liens than the Liens in respect of the Indebtedness being
Refinanced and (B) do not extend to or cover any property or assets of the
Company or any of its Restricted Subsidiaries not securing the Indebtedness so
Refinanced; and (F) Permitted Liens.
 
  Prohibition on Incurrence of Senior Subordinated Debt. The Company and the
Guarantors will not incur or suffer to exist Indebtedness that is senior in
right of payment to the Notes or the Guarantees, as the case may be, and
subordinate in right of payment by its terms to any other Indebtedness of the
Company or such Guarantor, as the case may be.
 
  Merger, Consolidation and Sale of Assets. The Company will not, in a single
transaction or series of related transactions, consolidate or merge with or
into any Person, or sell, assign, transfer, lease, convey or otherwise dispose
of (or cause or permit any Restricted Subsidiary of the Company to sell,
assign, transfer, lease, convey or otherwise dispose of) all or substantially
all of the Company's assets (determined on a consolidated basis for the
Company and the Company's Restricted Subsidiaries) whether as an entirety or
substantially as an entirety to any Person unless (i) either (1) the Company
shall be the surviving or continuing corporation or (2) the Person (if other
than the Company) formed by such consolidation or into which the Company is
merged or the Person which acquires by sale, assignment, transfer, lease,
conveyance or other disposition the properties and assets of the Company and
of the Company's Restricted Subsidiaries substantially as an entirety (the
"Surviving Entity") (x) shall be a corporation organized and validly existing
under the laws of the United States or any State thereof or the District of
Columbia and (y) shall expressly assume, by supplemental indenture (in form
and substance satisfactory to the Trustee), executed and delivered to the
Trustee, the due and punctual payment of the principal of, and premium, if
any, and interest on all of the Notes and the performance of every covenant of
the Notes and the Indenture on the part of the Company to be performed or
observed; (ii)
 
                                      64
<PAGE>
 
immediately after giving effect to such transaction on a pro forma basis and
the assumption contemplated by clause (i)(2)(y) above (including giving effect
to any Indebtedness and Acquired Indebtedness incurred or anticipated to be
incurred in connection with or in respect of such transaction), the Company or
such Surviving Entity, as the case may be, shall be able to incur at least
$1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant
to the "Limitation on Incurrence of Additional Indebtedness" covenant; (iii)
immediately before and immediately after giving effect to such transaction and
the assumption contemplated by clause (i)(2)(y) above (including, without
limitation, giving effect to any Indebtedness and Acquired Indebtedness
incurred or anticipated to be incurred and any Lien granted in connection with
or in respect of the transaction), no Default or Event of Default shall have
occurred or be continuing; and (iv) the Company or the Surviving Entity, as
the case may be, shall have delivered to the Trustee an officers' certificate
and an opinion of counsel, each stating that such consolidation, merger, sale,
assignment, transfer, lease, conveyance or other disposition and, if a
supplemental indenture is required in connection with such transaction, such
supplemental indenture comply with the applicable provisions of the Indenture
and that all conditions precedent in the Indenture relating to such
transaction have been satisfied.
 
  Notwithstanding the foregoing, the merger of the Company with an Affiliate
incorporated solely for the purpose of reincorporating the Company in another
jurisdiction shall be permitted.
 
  For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties or assets of one or more Restricted
Subsidiaries of the Company the Capital Stock of which constitutes all or
substantially all of the properties and assets of the Company, shall be deemed
to be the transfer of all or substantially all of the properties and assets of
the Company.
 
  The Indenture will provide that upon any consolidation, combination or
merger or any transfer of all or substantially all of the assets of the
Company in accordance with the foregoing, in which the Company is not the
continuing corporation, the successor Person formed by such consolidation or
into which the Company is merged or to which such conveyance, lease or
transfer is made shall succeed to, and be substituted for, and may exercise
every right and power of, the Company under the Indenture and the Notes with
the same effect as if such Surviving Entity had been named as such.
 
  Each Guarantor (other than any Guarantor whose Guarantee is to be released
in accordance with the terms of the Guarantee and the Indenture in connection
with any transaction complying with the provisions of "--Limitation on Asset
Sales") will not, and the Company will not cause or permit any Guarantor to,
consolidate with or merge with or into any Person other than the Company or
any other Guarantor unless (i) the entity formed by or surviving any such
consolidation or merger (if other than the Guarantor) or to which such sale,
lease, conveyance or other disposition shall have been made is a corporation
organized and existing under the laws of the United States or any State
thereof or the District of Columbia; (ii) such entity assumes by supplemental
indenture all of the obligations of the Guarantor on the Guarantee; (iii)
immediately after giving effect to such transaction, no Default or Event of
Default shall have occurred and be continuing; and (iv) immediately after
giving effect to such transaction and the use of any net proceeds therefrom on
a pro forma basis, the Company could satisfy the provisions of clause (ii) of
the first paragraph of this covenant. Any merger or consolidation of a
Guarantor with and into the Company (with the Company being the surviving
entity) or another Guarantor that is a Wholly Owned Restricted Subsidiary of
the Company need only comply with clause (iv) of the first paragraph of this
covenant.
 
  Limitations on Transactions with Affiliates. (a) The Company will not, and
will not permit any of its Restricted Subsidiaries to, directly or indirectly,
enter into or permit to exist any transaction or series of related
transactions (including, without limitation, the purchase, sale, lease or
exchange of any property or the rendering of any service) with, or for the
benefit of, any of its Affiliates (each an "Affiliate Transaction"), other
than (x) Affiliate Transactions permitted under paragraph (b) below and (y)
Affiliate Transactions on terms that are no less favorable than those that
might reasonably have been obtained in a comparable transaction at such time
on an arm's-length basis from a Person that is not an Affiliate of the Company
or such Restricted Subsidiary. All
 
                                      65
<PAGE>
 
Affiliate Transactions (and each series of related Affiliate Transactions
which are similar or part of a common plan) involving aggregate payments or
other property with a fair market value in excess of $1.0 million shall be
approved by the Board of Directors of the Company or such Restricted
Subsidiary, as the case may be, such approval to be evidenced by a Board
Resolution stating that such Board of Directors has determined that such
transaction complies with the foregoing provisions. If the Company or any
Restricted Subsidiary of the Company enters into an Affiliate Transaction (or
a series of related Affiliate Transactions related to a common plan) that
involves an aggregate fair market value of more than $10.0 million, the
Company or such Restricted Subsidiary, as the case may be, shall, prior to the
consummation thereof, obtain a favorable opinion as to the fairness of such
transaction or series of related transactions to the Company or the relevant
Restricted Subsidiary, as the case may be, from a financial point of view,
from an Independent Financial Advisor and file the same with the Trustee.
 
  (b) The restrictions set forth in clause (a) shall not apply to (i)
reasonable fees and compensation paid to and indemnity provided on behalf of,
officers, directors, employees or consultants of the Company or any Restricted
Subsidiary of the Company as determined in good faith by the Company's Board
of Directors; (ii) transactions exclusively between or among the Company and
any of its Wholly Owned Restricted Subsidiaries or exclusively between or
among such Wholly Owned Restricted Subsidiaries, provided such transactions
are not otherwise prohibited by the Indenture; (iii) any agreement as in
effect as of the Issue Date or any amendment thereto or any transaction
contemplated thereby (including pursuant to any amendment thereto) in any
replacement agreement thereto so long as any such amendment or replacement
agreement is not more disadvantageous to the Holders in any material respect
than the original agreement as in effect on the Issue Date; (iv) Restricted
Payments permitted by the Indenture; (v) transactions in which the Company or
any of its Restricted Subsidiaries, as the case may be, delivers to the
Trustee a letter from an Independent Financial Advisor stating that such
transaction is fair to the Company or such Restricted Subsidiary from a
financial point of view or meets the requirements of the first sentence of
paragraph (a) above; (vi) the existence of, or the performance by the Company
or any of its Restricted Subsidiaries of its obligations under the terms of,
any stockholders agreement (including any registration rights agreement or
purchase agreement related thereto) to which it is a party as of the Issue
Date and any similar agreements which it may enter into thereafter; provided,
however, that the existence of, or the performance by the Company or any of
its Restricted Subsidiaries of obligations under, any future amendment to any
such existing agreement or under any similar agreement entered into after that
Issue Date shall only be permitted by this clause to the extent that the terms
of any such, amendment or new agreement are not otherwise disadvantageous to
the holders of the Notes in any material respect; (vii) loans to employees of
the Company and its Subsidiaries which are approved by the Board of Directors
of the Company in good faith; (viii) the payment of all fees and expenses
related to the Transactions; and (ix) transactions with customers, clients,
suppliers, or purchasers or sellers of goods or services, in each case in the
ordinary course of business and otherwise in compliance with the terms of the
Indenture, which are fair to the Company or its Restricted Subsidiaries, in
the reasonable determination of the Board of Directors of the Company or the
senior management thereof, or are on terms at least as favorable as might
reasonably have been obtained at such time from an unaffiliated party.
 
  Additional Subsidiary Guarantees. If the Company or any of its Restricted
Subsidiaries transfers or causes to be transferred, in one transaction or a
series of related transactions, any property to any domestic Restricted
Subsidiary that is not a Guarantor, or if the Company or any of its Restricted
Subsidiaries shall organize, acquire or otherwise invest in another domestic
Restricted Subsidiary having total equity value in excess of $1.0 million,
then such transferee or acquired or other Restricted Subsidiary shall (i)
execute and deliver to the Trustee a supplemental indenture in form reasonably
satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall
unconditionally guarantee all of the Company's obligations under the Notes and
the Indenture on the terms set forth in the Indenture and (ii) deliver to the
Trustee an opinion of counsel that such supplemental indenture has been duly
authorized, executed and delivered by such Restricted Subsidiary and
constitutes a legal, valid, binding and enforceable obligation of such
Restricted Subsidiary. Thereafter, such Restricted Subsidiary shall be a
Guarantor for all purposes of the Indenture.
 
 
                                      66

  Reports to Holders. The Indenture will provide that the Company will deliver
to the Trustee within 15 days after the filing of the same with the
Commission, copies of the quarterly and annual reports and of the information,
documents and other reports, if any, which the Company is required to file
with the Commission pursuant to Section 13 or 15(d) of the Exchange Act. The
Indenture further provides that, notwithstanding that the Company may not be
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company will file with the Commission, to the extent permitted, and
provide the Trustee and Holders with such annual reports and such information,
documents and other reports specified in Sections 13 and 15(d) of the Exchange
Act. The Company will also comply with the other provisions of TIA (S) 314(a).
 
EVENTS OF DEFAULT
 
  The following events are defined in the Indenture as "Events of Default":
 
    (i) the failure to pay interest on any Notes when the same becomes due
  and payable and the default continues for a period of 30 days (whether or
  not such payment shall be prohibited by the subordination provisions of the
  Indenture);
 
    (ii) the failure to pay the principal on any Notes, when such principal
  becomes due and payable, at maturity, upon redemption or otherwise
  (including the failure to make a payment to purchase Notes tendered
  pursuant to a Change of Control Offer or a Net Proceeds Offer) (whether or
  not such payment shall be prohibited by the subordination provisions of the
  Indenture);
 
    (iii) a default in the observance or performance of any other covenant or
  agreement contained in the Indenture which default continues for a period
  of 30 days after the Company receives written notice specifying the default
  (and demanding that such default be remedied) from the Trustee or the
  Holders of at least 25% of the outstanding principal amount of the Notes;
 
    (iv) the failure to pay at final stated maturity (giving effect to any
  applicable grace periods and any extensions thereof) the principal amount
  of any Indebtedness of the Company or any Restricted Subsidiary of the
  Company, or the acceleration of the final stated maturity of any such
  Indebtedness if the aggregate principal amount of such Indebtedness,
  together with the principal amount of any other such Indebtedness in
  default for failure to pay principal at final stated maturity or which has
  been accelerated, aggregates $5.0 million or more at any time;
 
    (v) one or more judgments in an aggregate amount in excess of $5.0
  million shall have been rendered against the Company or any of its
  Restricted Subsidiaries and such judgments remain undischarged, unpaid or
  unstayed for a period of 60 days after such judgment or judgments become
  final and non-appealable;
 
    (vi) certain events of bankruptcy affecting the Company or any of its
  Significant Subsidiaries; or
 
    (vii) any of the Guarantees ceases to be in full force and effect or any
  of the Guarantees is declared to be null and void and unenforceable or any
  of the Guarantees is found to be invalid or any of the Guarantors denies
  its liability under its Guarantee (other than by reason of release of a
  Guarantor in accordance with the terms of the Indenture).
 
  If an Event of Default (other than an Event of Default specified in clause
(vi) above with respect to the Company) shall occur and be continuing, the
Trustee or the Holders of at least 25% in principal amount of outstanding
Notes may declare the principal of and accrued interest on all the Notes to be
due and payable by notice in writing to the Company and the Trustee specifying
the respective Event of Default and that it is a "notice of acceleration" (the
"Acceleration Notice"), and the same (i) shall become immediately due and
payable or (ii) if there are any amounts outstanding under the Credit
Agreement, shall become immediately due and payable upon the first to occur of
an acceleration under the Credit Agreement or 5 business days after receipt by
the Company and the Representative under the Credit Agreement of such
Acceleration Notice. If an Event of Default specified in clause (vi) above
with respect to the Company occurs and is continuing, then all unpaid
principal of, and premium, if any, and accrued and unpaid interest on all of
the outstanding Notes shall ipso
 
                                      67
<PAGE>
 
facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder.
 
  The Indenture will provide that, at any time after a declaration of
acceleration with respect to the Notes as described in the preceding
paragraph, the Holders of a majority in principal amount of the Notes may
rescind and cancel such declaration and its consequences (i) if the rescission
would not conflict with any judgment or decree, (ii) if all existing Events of
Default have been cured or waived except nonpayment of principal or interest
that has become due solely because of the acceleration, (iii) to the extent
the payment of such interest is lawful, interest on overdue installments of
interest and overdue principal, which has become due otherwise than by such
declaration of acceleration, has been paid, (iv) if the Company has paid the
Trustee its reasonable compensation and reimbursed the Trustee for its
expenses, disbursements and advances and (v) in the event of the cure or
waiver of an Event of Default of the type described in clause (vi) of the
description above of Events of Default, the Trustee shall have received an
officers' certificate and an opinion of counsel that such Event of Default has
been cured or waived. No such rescission shall affect any subsequent Default
or impair any right consequent thereto.
 
  The Holders of a majority in principal amount of the Notes may waive any
existing Default or Event of Default under the Indenture, and its
consequences, except a default in the payment of the principal of or interest
on any Notes.
 
  Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture and under the TIA. Subject to the provisions of the
Indenture relating to the duties of the Trustee, the Trustee is under no
obligation to exercise any of its rights or powers under the Indenture at the
request, order or direction of any of the Holders, unless such Holders have
offered to the Trustee reasonable indemnity. Subject to all provisions of the
Indenture and applicable law, the Holders of a majority in aggregate principal
amount of the then outstanding Notes have the right to direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee.
 
  Under the Indenture, the Company is required to provide an officers'
certificate to the Trustee promptly upon any such officer obtaining knowledge
of any Default or Event of Default (provided that such officers shall provide
such certification at least annually whether or not they know of any Default
or Event of Default) that has occurred and, if applicable, describe such
Default or Event of Default and the status thereof.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS
 
  No director, officer, employee or stockholder of the Company, as such, shall
have any liability for any obligations of the Company under the Notes or the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives
and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
  The Company may, at its option and at any time, elect to have its
obligations and the obligations of the Guarantors discharged with respect to
the outstanding Notes ("Legal Defeasance"). Such Legal Defeasance means that
the Company shall be deemed to have paid and discharged the entire
indebtedness represented by the outstanding Notes, except for (i) the rights
of Holders to receive payments in respect of the principal of, premium, if
any, and interest on the Notes when such payments are due, (ii) the Company's
obligations with respect to the Notes concerning issuing temporary Notes,
registration of Notes, mutilated, destroyed, lost or stolen Notes and the
maintenance of an office or agency for payments, (iii) the rights, powers,
trust, duties and immunities of the Trustee and the Company's obligations in
connection therewith and (iv) the Legal Defeasance provisions of the
Indenture. In addition, the Company may, at its option and at any time, elect
to have the obligations of the Company released with respect to certain
covenants that are described in the Indenture ("Covenant Defeasance") and
thereafter any omission to comply with such obligations shall not constitute a
 
                                      68
<PAGE>
 
Default or Event of Default with respect to the Notes. In the event Covenant
Defeasance occurs, certain events (not including non-payment, bankruptcy,
receivership, reorganization and insolvency events) described under "Events of
Default" will no longer constitute an Event of Default with respect to the
Notes.
 
  In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders cash in U.S. dollars, non-callable U.S. government obligations,
or a combination thereof, in such amounts as will be sufficient, in the
opinion of a nationally recognized firm of independent public accountants, to
pay the principal of, premium, if any, and interest on the Notes on the stated
date for payment thereof or on the applicable redemption date, as the case may
be; (ii) in the case of Legal Defeasance, the Company shall have delivered to
the Trustee an opinion of counsel in the United States reasonably acceptable
to the Trustee confirming that (A) the Company has received from, or there has
been published by, the Internal Revenue Service a ruling or (B) since the date
of the Indenture, there has been a change in the applicable federal income tax
law, in either case to the effect that, and based thereon such opinion of
counsel shall confirm that, the Holders will not recognize income, gain or
loss for federal income tax purposes as a result of such Legal Defeasance and
will be subject to federal income tax on the same amounts, in the same manner
and at the same times as would have been the case if such Legal Defeasance had
not occurred; (iii) in the case of Covenant Defeasance, the Company shall have
delivered to the Trustee an opinion of counsel in the United States reasonably
acceptable to the Trustee confirming that the Holders will not recognize
income, gain or loss for federal income tax purposes as a result of such
Covenant Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case
if such Covenant Defeasance had not occurred; (iv) no Default or Event of
Default shall have occurred and be continuing on the date of such deposit or
insofar as Events of Default from bankruptcy or insolvency events are
concerned, at any time in the period ending on the 91st day after the date of
deposit; (v) such Legal Defeasance or Covenant Defeasance shall not result in
a breach or violation of, or constitute a default under the Indenture or any
other material agreement or instrument to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries is
bound; (vi) the Company shall have delivered to the Trustee an officers'
certificate stating that the deposit was not made by the Company with the
intent of preferring the Holders over any other creditors of the Company or
with the intent of defeating, hindering, delaying or defrauding any other
creditors of the Company or others; (vii) the Company shall have delivered to
the Trustee an officers' certificate and an opinion of counsel, each stating
that all conditions precedent provided for or relating to the Legal Defeasance
or the Covenant Defeasance have been complied with; (viii) the Company shall
have delivered to the Trustee an opinion of counsel to the effect that (A) the
trust funds will not be subject to any rights of holders of Senior Debt,
including, without limitation, those arising under the Indenture and (B)
assuming no intervening bankruptcy of the Company between the date of deposit
and the 91st day following the date of the deposit and that no Holder is an
insider of the Company, after the 91st day following the date of the deposit,
the trust funds will not be subject to the effect of any applicable
bankruptcy, insolvency, reorganization or similar laws affecting creditors'
rights generally; and (ix) certain other customary conditions precedent are
satisfied. Notwithstanding the foregoing, the opinion of counsel required by
clause (ii) above need not be delivered if all Notes not theretofore delivered
to the Trustee for cancellation (x) have become due and payable, (y) will
become due and payable on the maturity date within one year or (z) are to be
called for redemption within one year under arrangements satisfactory to the
Trustee for the giving of notice of redemption by the Trustee in the name, and
at the expense, of the Company.
 
SATISFACTION AND DISCHARGE
 
  The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights of registration or transfer or exchange of the
Notes, as expressly provided for in the Indenture) as to all outstanding Notes
when (i) either (a) all the Notes theretofore authenticated and delivered
(except lost, stolen or destroyed Notes which have been replaced or paid and
Notes for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust) have been delivered to the Trustee for
cancellation or (b) all Notes not theretofore delivered to the Trustee for
cancellation have become due and payable and the Company has irrevocably
deposited or caused to
 
                                      69
<PAGE>
 
be deposited with the Trustee funds in an amount sufficient to pay and
discharge the entire Indebtedness on the Notes not theretofore delivered to
the Trustee for cancellation, for principal of, premium, if any, and interest
on the Notes to the date of deposit together with irrevocable instructions
from the Company directing the Trustee to apply such funds to the payment
thereof at maturity or redemption, as the case may be; (ii) the Company has
paid all other sums payable under the Indenture by the Company; and (iii) the
Company has delivered to the Trustee an officers' certificate and an opinion
of counsel stating that all conditions precedent under the Indenture relating
to the satisfaction and discharge of the Indenture have been complied with.
 
MODIFICATION OF THE INDENTURE
 
  From time to time, the Company, the Guarantors and the Trustee, without the
consent of the Holders, may amend the Indenture for certain specified
purposes, including curing ambiguities, defects or inconsistencies, so long as
such change does not, in the opinion of the Trustee, adversely affect the
rights of any of the Holders in any material respect. In formulating its
opinion on such matters, the Trustee will be entitled to rely on such evidence
as it deems appropriate, including, without limitation, solely on an opinion
of counsel. Other modifications and amendments of the Indenture may be made
with the consent of the Holders of a majority in principal amount of the then
outstanding Notes issued under the Indenture, except that, without the consent
of each Holder affected thereby, no amendment may (i) reduce the amount of
Notes whose Holders must consent to an amendment; (ii) reduce the rate of or
change or have the effect of changing the time for payment of interest,
including defaulted interest, on any Notes; (iii) reduce the principal of or
change or have the effect of changing the fixed maturity of any Notes, or
change the date on which any Notes may be subject to redemption or repurchase,
or reduce the redemption or repurchase price therefor; (iv) make any Notes
payable in money other than that stated in the Notes; (v) make any change in
provisions of the Indenture protecting the right of each Holder to receive
payment of principal of and interest on such Note on or after the due date
thereof or to bring suit to enforce such payment, or permitting Holders of a
majority in principal amount of Notes to waive Defaults or Events of Default;
(vi) amend, change or modify in any material respect the obligation of the
Company to make and consummate a Change of Control Offer in the event of a
Change of Control which has occurred or make and consummate a Net Proceeds
Offer with respect to any Asset Sale that has been consummated or modify any
of the provisions or definitions with respect thereto after a Change of
Control has occurred or the subject Asset Sale has been consummated; (vii)
modify or change any provision of the Indenture or the related definitions
affecting the subordination or ranking of the Notes or any Guarantee in a
manner which adversely affects the Holders; or (viii) release any Guarantor
from any of its obligations under its Guarantee or the Indenture otherwise
than in accordance with the terms of the Indenture.
 
GOVERNING LAW
 
  The Indenture will provide that it, the Notes and the Guarantees will be
governed by, and construed in accordance with, the laws of the State of New
York but without giving effect to applicable principles of conflicts of law to
the extent that the application of the law of another jurisdiction would be
required thereby.
 
THE TRUSTEE
 
  The Indenture will provide that, except during the continuance of an Event
of Default, the Trustee will perform only such duties as are specifically set
forth in the Indenture. During the existence of an Event of Default, the
Trustee will exercise such rights and powers vested in it by the Indenture,
and use the same degree of care and skill in its exercise as a prudent man
would exercise or use under the circumstances in the conduct of his own
affairs.
 
  The Indenture and the provisions of the TIA contain certain limitations on
the rights of the Trustee, should it become a creditor of the Company, to
obtain payments of claims in certain cases or to realize on certain property
received in respect of any such claim as security or otherwise. Subject to the
TIA, the Trustee will be permitted to engage in other transactions; provided
that if the Trustee acquires any conflicting interest as described in the TIA,
it must eliminate such conflict or resign.

presently intend to make a market in the Notes, as permitted by applicable
laws and regulations. The Underwriters are not obligated, however, to make a
market in the Notes, and any such market making may be discontinued at any
time in the sole discretion of the Underwriters. There can be no assurance
that an active public market for the Notes will develop.

respect thereof.

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

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

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

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
       (INFORMATION AT SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1996 AND 1997 IS UNAUDITED)
 
valuation allowance is established for deferred tax assets unless their
realization is considered more likely than not. Alliance's provision for
income taxes is the sum of the change in the balance of deferred taxes between
the beginning and the end of the period plus income taxes currently payable.
 
  INVESTMENT TAX CREDITS--Alliance accounts for investment tax credits under
the flow through method.
 
  FAIR VALUES OF FINANCIAL INSTRUMENTS--FASB Statement No. 107, "Disclosures
about Fair Value of Financial Instruments," requires disclosure of fair value
information about financial instruments, whether or not recognized in the
balance sheet, for which it is practicable to estimate that value. In cases
where quoted market prices are not available, fair values are based on
estimates using present value or other valuation techniques. Those techniques
are significantly affected by the assumptions used, including the discount
rate and estimates of future cash flows. In that regard, the derived fair
value estimated cannot be substantiated by comparison to independent markets
and, in many cases, could not be realized in immediate settlement of the
instrument. Statement 107 excludes certain financial instruments and all
nonfinancial instruments from its disclosure requirements. Accordingly, the
aggregate fair value amounts presented do not represent the underlying value
of Alliance.
 
  The following methods and assumptions were used by Alliance in estimating
its fair value disclosures for financial instruments:
 
  Cash and short-term investments--The carrying amount reported in the balance
sheet for cash and cash equivalents approximates its fair value.
 
  Long-term debt--The fair values of Alliance's long-term debt are estimated
using discounted cash flow analyses, based on Alliance's current incremental
rates for similar types of borrowing arrangements.
 
    The carrying amounts and estimated fair values of Alliance's financial
                          instruments are as follows:

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

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

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

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

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

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

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

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

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

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

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

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
       (INFORMATION AT SEPTEMBER 30, 1997 AND FOR THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1996 AND 1997 IS UNAUDITED)
 
stock (the "New Option Shares") will be available for grant. The New Option
Shares will be allocated in amounts agreed upon between Apollo and the
Company. Of the New Option Shares, 50% will vest in equal increments over four
years ending on the fourth anniversary of the last day of the consummation of
the Recapitalization. The remaining 50% will vest seven and one-half years
after the date of grant, subject to acceleration if certain per-share equity
targets are achieved. Vesting of New Options occurs only during an employee's
term of employment. The exercise price for the New Options is expected to be
at the fair market value at a grant date (i.e., $11.00 per share at the
consummation of the Recapitalization)."
 
  As a part of the new financing to be provided, Alliance plans to sell $165
million of Senior Subordinated Notes (the "Notes") in an underwritten public
offering. The Notes are to be unconditionally guaranteed, on a senior
subordinated basis, jointly and severally, by all significant direct and
indirect consolidated subsidiaries of Alliance, which consist of Royal Medical
Health Services, Inc., Alliance Imaging of Central Georgia, Inc., Alliance
Imaging of Ohio, Inc. and Alliance Imaging of Michigan, Inc. (collectively,
the "Subsidiary Guarantors"). Separate financial statements of the Subsidiary
Guarantors are not included herein because such guarantors are jointly and
severally liable with respect to Alliance's obligations pursuant to the Notes,
and the aggregate net assets, earnings and equity of the Subsidiary Guarantors
and Alliance are substantially equivalent to the net assets, earnings and
equity of Alliance on a consolidated basis. Accordingly, management has
determined that separate financial statements and other disclosures concerning
the Subsidiary Guarantors would not provide material information to
prospective purchasers of the Notes. Combined summarized financial information
for the Subsidiary Guarantors is set forth below (in thousands):

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The Company's Restated Certificate of Incorporation, By-Laws and
indemnification agreements with officers and directors provide for
indemnification to the full extent permitted by the laws of the State of
Delaware against and with respect to threatened, pending or completed actions,
suits or proceedings arising from or alleged to arise from, a party's actions
or omissions as a director, officer, employee or agent of the Company or of
any other corporation, partnership, joint venture, trust or other enterprise
which has served in such capacity at the request of the Company if such acts
or omissions occurred or were or are alleged to have occurred, while said
party was a director or officer of the Company; provided, however, the Company
shall not indemnify any director or officer in an action against the Company
unless the Company shall have consented to such action. Generally, under
Delaware law, indemnification will only be available where an officer or
director can establish that he/she acted in good faith and in a manner which
was reasonably believed to be in or not opposed to the best interests of the
Company.
 
  Section 145 of the Delaware Law provides that a corporation may indemnify a
director, officer, employee or agent made a party to an action by reason of
the fact that such person was a director, officer, employee or agent of the
corporation or was serving at the request of the corporation against expenses
actually incurred by such person in connection with such action if such person
acted in good faith and in a manner such person reasonably believed to be in,
or not opposed to, the best interest of the corporation with respect to any
criminal action, and had no reasonable cause to believe his conduct was
unlawful. Delaware Law does not permit a corporation to eliminate a director's
duty of care, and the provisions of the Company's Amended and Restated
Certificate of Incorporation have no effect on the availability of equitable
remedies such as injunction or rescission, based upon a director's breach of
the duty of care. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers or persons controlling
the Company pursuant to the foregoing provisions and agreements, the Company
has been informed that in the opinion of the Staff of the Securities and
Exchange Commission such indemnification is against policy as expressed in the
Securities Act and is therefore unenforceable.
 
  Reference is made to the form of Underwriting Agreement filed as Exhibit 1
to this Registration Statement, which provides for indemnification of the
directors and officers of the Company signing the Registration Statement and
certain controlling persons of the Company against certain liabilities,
including those arising under the Securities Act, in certain instances by the
Underwriters.

ITEM 17. UNDERTAKINGS.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the DGCL, the Certificate of Incorporation and By-laws,
or otherwise, the Registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Securities Act, and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  The Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  registration statement in reliance upon Rule 430A and contained in the form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

     ---------
     it was or is declared effective, and including all financial schedules and
     exhibits thereto and including any information omitted therefrom pursuant
     to Rule 430A under the Act and included in the Prospectus (as hereinafter
     defined); the term "Preliminary Prospectus" means each prospectus, subject

     such Preliminary Prospectus or the Prospectus (all such incorporated

                                                     ---------

        (b)   The Commission has not issued any order preventing or suspending
     the use of any Preliminary Prospectus. When any Preliminary Prospectus was
     filed with the Commission it (x) complied in all material respects with the
     requirements of the Act and (y) did not include any untrue statement of a
     material fact or omit to state any material fact necessary in order to make

     thereto was or is declared effective, it (1) contained or will contain all
     statements required to be stated therein in accordance with, and complied
     or will comply in all material respects with, the requirements of the Act

     document incorporated by reference in any Preliminary Prospectus or the
     Prospectus, when filed with the Commission, (A) complied in all material
     respects with the requirements of the Act and the Exchange Act and (B) did
     not include any untrue statement of a material fact or omit to

                                      -5-

     state any material fact necessary to make the statements therein, in the
     light of the circumstances under which they were made, not misleading. The
     foregoing provisions of this paragraph (b) do not apply to statements or
     omissions made in any Preliminary Prospectus, the Registration Statement or
     any amendment thereto or the Prospectus or any amendment or supplement
     thereto in reliance upon and in conformity with written information
     furnished to Alliance by the Underwriters specifically for use therein or

     Statement.
     
        (c)   At the Closing Date after giving effect to the Transactions,
     Alliance will have the authorized, issued and outstanding capitalization
     set forth in the Prospectus under the caption "Pro Forma Capitalization";
     all of the outstanding shares of capital stock of Alliance are duly
     authorized and validly issued, fully paid and nonassessable and not issued
     in violation of any preemptive or similar rights. Except as described in
     the Prospectus, all of the outstanding shares of capital stock of Alliance
     when issued were free and clear of all liens, encumbrances, equities and
     claims or restrictions on transferability (other than those imposed by the
     Act and the securities or "Blue Sky" laws of certain jurisdictions), or
     voting; except as described in the Prospectus, there are no (i) options,
     warrants or other rights to purchase, (ii) agreements or other obligations
     to issue or (iii) other rights to convert any obligation into, or exchange
     any securities for, shares of capital stock of or ownership interests in
     Alliance. Except as described in the Registration Statement, Alliance does
     not own, directly or indirectly, any shares of capital stock or any other

     attached hereto (each, a "Subsidiary" and collectively, the "Subsidiaries")

     their respective jurisdictions of incorporation, with all requisite
     corporate power and authority (corporate or otherwise) to own or lease
     their properties and conduct their businesses as now conducted. Each of
     Alliance and the Subsidiaries is duly qualified to do business as a foreign
     corporation in good standing in all other jurisdictions where the ownership
     or leasing of its properties or the conduct of its businesses requires such
     qualification, except where the failure to be so qualified would not have a
     material adverse effect on the business, condition (financial or other) or
     results of operations or prospects of Alliance and the Subsidiaries, taken
     as a whole (any such event, a "Material Adverse Effect").
                                    -----------------------

          (e)   Alliance and each of the Guarantors has all requisite corporate
     power and authority to execute, deliver and perform its respective
     obligations under this Agreement and the other Operative Documents and to
     consummate the transactions contemplated hereby and thereby, including,
     without limitation, the power and authority to issue, sell and deliver the
     Securities as contemplated by this Agreement.

          (h)   The Guarantees have been duly and validly authorized for

          (k)   Alliance and each of the Guarantors has the requisite corporate
     power and authority to enter into the Transactions (to the extent each is a
     party thereto).

          (l)   Except as described in the Prospectus, no consent, approval,
     authorization or order of any court or governmental agency or body is
     required for the performance of the Operative Documents or the Transactions
     by Alliance and the Guarantors or of any of the transactions contemplated
     hereby or thereby, except such as have been obtained or are contemplated to
     be obtained by the Prospectus and such as may be required under the Act,
     the Trust Indenture Act or state securities or "Blue Sky" laws in
     connection with the purchase and distribution of the Securities by the
     Underwriters and in connection with the Transactions. Neither Alliance or
     any of the Subsidiaries is (i) in violation of its certificate of
     incorporation or bylaws, (ii) in violation of any statute, judgment,
     decree, order, rule or regulation applicable to any of them or any of their

     to which any 
<PAGE>
 
                                      -9-

     of them is subject (collectively, the "Contracts"), which default would
                                            ---------
     have a Material Adverse Effect.

          (m)   The execution, delivery and performance by Alliance and the
     Guarantors of the Operative Documents and the consummation of the
     Transactions (to the extent each such person is a party thereto) and the
     transactions contemplated hereby and thereby will not conflict with or
     constitute or result in a breach or violation of any of (x) the terms or
     provisions of, or constitute a default by any of them under, any of the
     Contracts, which conflict, breach, violation or default, individually or in
     the aggregate, would have a Material Adverse Effect, (y) the certificate of
     incorporation or bylaws of any such person, or (z) any statute, judgment,
     decree, order, rule or regulation (excluding state securities and "Blue
     Sky" laws) of any court or governmental agency or other body applicable to
     any such person, or any of their respective properties, which conflict,
     breach, violation or default, individually or in the aggregate, would have
     a Material Adverse Effect.

          (n)   Each of the Transactions conforms in all material respects to
     the description thereof in the Prospectus.

          (o)   The fair value and present fair saleable value of the assets of
     Alliance and each of the Guarantors exceeds the sum of its stated
     liabilities and identified contingent liabilities; and after giving effect
     to the Transactions and the consummation of the transactions contemplated
     thereby and by the Prospectus, Alliance and each of the Guarantors will not
     be (a) left with unreasonably small capital with which to carry on its
     business as it is proposed to be conducted, (b) unable to pay its debts
     (contingent or otherwise) as they mature or (c) insolvent.

          (p)   The audited and unaudited consolidated financial statements of
     Alliance and the related notes included in the Prospectus present fairly in
     all material respects the consolidated financial position, results of
     operations and cash flows of Alliance at the dates and for the periods to

     information (including the notes thereto) included in the Prospectus have
     been prepared in accordance with applicable requirements of Regulation S-X

     bases described therein.  The assumptions used in the preparation of the
     pro forma financial statements and other pro forma financial information

     referred to therein in all material respects.

     inquiry or investigation to which Alliance or the Guarantors or any of
     their respective property is subject, before or brought by any court or
     governmental agency or body, which could reasonably be expected to have a
     Material Adverse Effect.

          (t)   Alliance and the Guarantors have obtained all licenses, permits,
     franchises and other governmental authorizations necessary to conduct their
     respective business as described in the Prospectus and the lack of which

          (u)   Subsequent to the respective dates as of which information is
     given in the Registration Statement and the Prospectus and except as
     described therein or contemplated thereby, none of Alliance or the
     Guarantors has incurred

                                                          ------
     comparable state law, and (F) no property or facility of Alliance or any of
     the Guarantors is (i) listed or, to Alliance's knowledge, proposed for
     listing on the National Priorities List under CERCLA or is (ii) listed in
     the Comprehensive Environmental Response, Compensation, Liability
     Information System List promulgated pursuant to CERCLA, or, to Alliance's
     knowledge, on any comparable list maintained by any state or local
     governmental authority; except, in the case of clauses (A), (B) and (D) for
     such noncompliance with applicable Environmental Laws, failures to make
     filings and provide notices under applicable Environmental Laws and
     recording of liens, charges, encumbrances or restrictions under any
     Environmental Laws that, individually or in the aggregate, has not had a
     Material Adverse Effect and would 
<PAGE>
 
                                      -12-

     not reasonably be expected to have a Material Adverse Effect

     For purposes of this Agreement, "Environmental Laws" means the common law
                                      ------------------
     and all applicable federal, state and local laws or regulations, codes,

     or, to the knowledge of Alliance, threatened.

          (x)   Each of Alliance and the Guarantors carries insurance (including
     self-insurance) in such amounts and covering such risks as would be
     obtained by companies in the same or similar businesses in the ordinary
     course for the conduct of its business and the value of its properties.

          (y)   Each of Alliance and the Guarantors has good title to all
     personal property described in the Prospectus as being owned by it and good

     existence of such liens, 
<PAGE>
 
                                      -13-

     charges, encumbrances or restrictions would not, individually or in the
     aggregate, have a Material Adverse Effect.

          (z)   None of Alliance or the Guarantors has any liability for any
     prohibited transaction or accumulated funding deficiency (within the
     meaning of Section 412 of the Code) or any complete or partial withdrawal
     liability with respect to any pension, profit sharing or other plan which
     is subject to the Employee Retirement Income Security Act of 1974, as
     amended ("ERISA"), to which Alliance or any of the Guarantors makes or
               -----
     ever has made a contribution and in which any employee of Alliance or any
     of the Guarantors is or has ever been a participant. With respect to such
     plans, Alliance and each of the Guarantors is in compliance in all material
     respects with all applicable provisions of ERISA.

          (aa)   Neither Alliance nor any of the Guarantors or any agent acting
     on behalf of them, has taken or will take any action that might cause this
     Agreement or the issuance or sale of the Securities to violate Regulation
     G, T, U or X of the Board of Governors of the Federal Reserve System as in
     effect on the Closing Date.

          (bb)   Neither Alliance nor any of the Guarantors is now, and after

     the Investment Company Act of 1940, as amended.

          (cc)   All taxes, assessments, fees and other charges (including,
     without limitation, withholding taxes, penalties, and interest) due or
     claimed to be due from Alliance and the Guarantors that are due and payable
     have been paid, other than those being contested in good faith or those
     currently payable without penalty or interest and for which an adequate
     reserve or accrual has been established in accordance with generally
     accepted accounting principles, and except where the failure so to pay
     would not, individually or in the aggregate, have a Material Adverse
<PAGE>
 
                                      -14-

     Effect. Neither Alliance or any of the Guarantors knows of any actual or
     proposed additional tax assessments for any fiscal period against Alliance
     or the Guarantors, individually or in the aggregate, which would have a
     Material Adverse Effect.

          (dd)   Alliance has delivered to the Underwriters a true and correct
     copy of each of the documents contemplated by the Transactions, together
     with all related agreements and all schedules and exhibits thereto, and
     there shall have been no material amendments, alterations, modifications or
     waivers of any of the provisions of any such documents since their
     respective dates of execution, other than any such amendments, alterations,
     modifications and waivers as to which the Underwriters have been advised in
     writing and which would be required to be disclosed in the Prospectus; and
     to the best knowledge of Alliance and the Guarantors there exists no event
     or condition which would constitute a default or an event of default under
     any of the documents contemplated by the Transactions which would result in
     a Material Adverse Effect or materially adversely affect the ability of
     Alliance and the Guarantors to consummate the Transactions.

          Any certificate signed by any officer of Alliance or any of the
Guarantors and delivered to the Underwriters or to counsel for the Underwriters
shall be deemed a joint and several representation and warranty by Alliance and
the Guarantors to each Underwriter as to the matters covered thereby.

          4.    Offering by the Underwriters.  After the Registration Statement
                ----------------------------
becomes effective, the Underwriters propose to offer for sale to the public the
Securities at the price and  upon the terms set forth in the Prospectus.


          5.    Certain Covenants.  Each of the Issuers covenants and agrees 
                -----------------
with the Underwriters that:

          (a)   The Issuers will use all reasonable efforts to cause the
     Registration Statement, if not effective at the time of execution of this
     Agreement, and any amendments thereto, to become effective promptly. If, at
     the time the Registration Statement becomes effective, any information
     shall have been omitted therefrom in reliance upon Rule 430A of the rules
     and regulations of the Commission under the Act, then immediately following
     the execution of this Agreement, the Issuers will prepare, and thereafter
     the Issuers will file or transmit for filing with the Commission in
     accordance with such Rule 430A and Rule 424(b) of the rules and regulations
     of the Commission under the Act, copies of an amended Prospectus relating
     to such Registration Statement, or, if required by such Rule 430A, a 
<PAGE>
 
                                      -16-

     post-effective amendment to such Registration Statement (including an
     amended Prospectus), containing all information so omitted. The Issuers
     will give each Underwriter notice of their intention to file any amendment
     to any Registration Statement (including any post-effective amendment) or
     any amendment or supplement to any Prospectus (including any revised
     prospectus which the Issuers propose for use by the Underwriters in
     connection with the offering of the Securities which differs from any
     prospectus on file at the Commission at the time the Registration Statement
     including such prospectus becomes effective, whether or not such revised
     prospectus is required to be filed pursuant to Rule 424(b) of the rules and
     regulations of the Commission under the Act), will furnish the Underwriters
     with copies of any such amendment or supplement a reasonable amount of time
     prior to such proposed filing or use, as the case may be, and will not file
     any such amendment or supplement or use any such prospectus to which the
     Underwriters shall reasonably object in writing or which is not in
     compliance with the Act unless the Company is advised that in the opinion
     of counsel such filing is required by applicable law. The Issuers will
     advise the Underwriters, promptly after any of them receive notice thereof,
     of the time when the Registration Statement or any amendment thereto has
     been filed or declared effective or the Prospectus or any amendment or
     supplement thereto has been filed and will provide evidence satisfactory to
     the Underwriters of such filing or effectiveness.

          (b)   The Issuers will advise the Underwriters, promptly after
     receiving notice or obtaining knowledge thereof, of (i) the issuance by the
     Commission of any stop order suspending the effectiveness of the
     Registration Statement or any amendment thereto or any order preventing or
     suspending the use of any Preliminary Prospectus or any Prospectus, or any
     amendment or supplement thereto, (ii) the suspension of the qualification
     of the Securities for offering or sale in any jurisdiction, (iii) the
     institution, threatening or contemplation of any proceeding for any such
     purpose or (iv) any request made by the Commission 
<PAGE>
 
                                      -17-

     for amending any Registration Statement, for amending or supplementing the
     Prospectus or for additional information. The Issuers will use their best
     efforts to prevent the issuance of any such stop order and, if any such
     stop order is issued, to obtain the withdrawal thereof as promptly as
     possible.

          (c)   The Issuers will cooperate with the Underwriters in arranging
     for the qualification of the Notes for offering and sale under the
     securities or "Blue Sky" laws of such jurisdictions as the Underwriters may
     designate and will continue such qualifications in effect for as long as
     may be necessary to complete the initial distribution of the Notes by the
     Underwriters; provided, however, that in connection therewith the Issuers
                   --------  -------
     shall not be required to qualify as a foreign corporation or to execute a
     general consent to service of process in any jurisdiction, to take any
     other action that would subject it to general service of process or to
     taxation in respect of doing business.

          (d)   If, at any time when a Prospectus relating to the Securities is
     required to be delivered under the Act, any event shall occur as a result
     of which it is necessary, in the opinion of counsel for the Underwriters,
     to amend or supplement any Prospectus in order to make such Prospectus not
     misleading in the light of the circumstances existing at the time it is
     delivered to a purchaser, or if for any other reason it shall be necessary
     to amend or supplement the Prospectus in order to comply with the Act and
     the Exchange Act, the Issuers shall (subject to Section 5(a)) forthwith
     amend or supplement such Prospectus so that, as so amended or supplemented,
     such Prospectus will not include an untrue statement of a material fact or
     omit to state a material fact necessary in order to make the statements
     therein, in the light of the circumstances existing at the time it is
     delivered to a purchaser, not misleading and will comply with the Act and
     the Exchange Act, and the Issuers will furnish to the Underwriters a
     reasonable number of copies of such amendment or supplement.

                                      -18-

          (e)   The Issuers will without charge, provide (i) to each Underwriter
     and to counsel for the Underwriters a signed copy of each registration
     statement originally filed with respect to the Securities and each
     amendment thereto (in each case including exhibits thereto) and (ii) so
     long as a prospectus relating to the Securities is required to be delivered
     under the Act, as many copies of the Preliminary Prospectus or Prospectus
     or any amendment or supplement thereto as the Underwriters may reasonably
     request.

          (f)   Subject to Section 5(a), the Issuers will timely complete all
     required filings and otherwise comply fully in a timely manner with all
     provisions of the Exchange Act and promptly file all reports and any
     definitive proxy or information statements required to be filed by the
     Issuers with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d)
     of the Exchange Act subsequent to the date of the Prospectus and for so
     long as the delivery of a prospectus is required in connection with the
     offer or sale of any of the Notes.

          (g)   The Issuers will make generally available to its security
     holders as soon as practicable, but not later than 90 days after the close
     of the period covered thereby, an earning statement (in form complying with
     the provisions of Rule 158 of the rules and regulations of the Commission
     under the Act) covering a twelve-month period beginning not later than the
     first day of the fiscal quarter of the Issuers next following the
     "effective date" (as defined in Rule 158) of the Registration Statement.

          (h)   The Issuers will apply the net proceeds from the sale of the
     Securities as set forth in the Prospectus.

          (i)   Prior to the Closing Date, the Issuers will furnish to the
     Underwriters, as soon as they have been prepared by or are available to the
     Issuers, a copy of any unaudited interim financial statements of the

     with respect to this Agreement or the Transactions before any court or
     governmental authority.

        (n)   The Underwriters shall have received certificates, dated the
     Closing Date, of the appropriate officers of Alliance and each of the
     Guarantors as to such person, to the effect that:

        (A)  The representations and warranties of such person in this Agreement

<PAGE>
 
                                      -24-

        (p)   On the Closing Date, the Underwriters shall have received copies

          8.    Indemnification and Contribution.  (a)  Each of the Issuers 
                --------------------------------
agree, jointly and severally, to indemnify and hold harmless each Underwriter,
and each person, if any, who controls any Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act, against any losses,
claims, damages or liabilities, joint or several, to which such Underwriter or
such controlling person may become subject under the Act, the Exchange Act or
otherwise, insofar as any such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon:

          (i)   any untrue statement or alleged untrue statement of any material
     fact contained in the Registration Statement or any amendment thereto or
     any Preliminary Prospectus or any Prospectus or any amendment or supplement
     thereto or

          (ii)   the omission or alleged omission to state, in the Registration
     Statement or any amendment thereto, any 
<PAGE>
 
                                      -25-

     Preliminary Prospectus or any Prospectus or any amendment or supplement
     thereto, a material fact required to be stated therein or necessary to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading, and will reimburse, as incurred, each
     Underwriter and each such controlling person for any reasonable and
     documented out-of-pocket legal or other expenses reasonably incurred by the
     Underwriters or such controlling person in connection with investigating,
     defending against or appearing as a third-party witness in connection with
     any such loss, claim, damage, liability or action; provided, however, that
                                                        --------  -------
     none of the Issuers will be liable in any such case to an Underwriter to
     the extent that any such loss, claim, damage or liability arises out of or
     is based upon any untrue statement or alleged untrue statement or omission
     or alleged omission made in the Registration Statement or any amendment
     thereto, any Preliminary Prospectus or any Prospectus or any amendment or
     supplement thereto, or any Application in reliance upon and in conformity
     with written information furnished to the Issuers by or on behalf of any of
     such Underwriter specifically for use therein; and provided, further, that
                                                        --------  -------
     none of the Issuers will be liable to an Underwriter or any person
     controlling such Underwriter with respect to any such untrue statement or
     omission made in any Preliminary Prospectus that is corrected in the
     Prospectus (or any amendment or supplement thereto) if the person asserting
     any such loss, claim, damage or liability purchased Securities from such
     Underwriter in reliance upon the Preliminary Prospectus or Prospectus but
     was not sent or given a copy of the Prospectus (as amended or supplemented)
     at or prior to the written confirmation of the sale of such Securities to
     such person in any case where such delivery of such Prospectus or
     Prospectus (as so amended or supplemented) is required by the Act, unless
     such failure to deliver such Prospectus (as amended or supplemented) was a
     result of noncompliance by the Issuers with Section 5(e)(ii) of this
     Agreement. This indemnity agreement will be in addition to any liability
     that the Issuers may otherwise have to the indemnified parties. 
<PAGE>
 
                                      -26-

     None of the Issuers will, without the prior written consent of the
     Underwriters, settle or compromise or consent to the entry of any judgment
     in any pending or threatened claim, action, suit or proceeding in respect
     of which indemnification from the Underwriters may be sought hereunder
     (whether or not the Underwriters or any person who controls either of the
     Underwriters within the meaning of Section 15 of the Act or Section 20 of
     the Exchange Act is a party to such claim, action, suit or proceeding),
     unless such settlement, compromise or consent includes an unconditional
     release of the Underwriters and each such controlling person from all
     liability arising out of such claim, action, suit or proceeding.

          (b)   Each Underwriter will severally and not jointly indemnify and
     hold harmless the Issuers, their directors, officers who signed the
     Registration Statement and each person, if any, who controls any of the
     Issuers within the meaning of Section 15 of the Act or Section 20 of the
     Exchange Act against any losses, claims, damages or liabilities to which
     any of the Issuers or any such director, officer or controlling person may
     become subject under the Act, the Exchange Act, or otherwise, insofar as
     such losses, claims, damages or liabilities (or actions in respect thereof)
     arise out of or are based upon (i) any untrue statement or alleged untrue
     statement of any material fact contained in the Registration Statement or
     any amendment thereto, any Preliminary Prospectus or any Prospectus or any
     amendment or supplement thereto or (ii) the omission or the alleged
     omission to state therein a material fact required to be stated in the
     Registration Statement or any amendment thereto, any Preliminary Prospectus
     or any Prospectus or any amendment or supplement thereto, or necessary to
     make the statements therein (in the case of any Preliminary Prospectus, any
     Prospectus or any amendment or supplement thereto, in the light of the
     circumstances under which such statements were made) not misleading, in
     each case to the extent, but only to the extent, that such untrue statement
     or alleged untrue statement or omission or alleged omission was made in
     reliance upon and in conformity with written information furnished to the
     Issuers by or on behalf of such Underwriter specifically for use 
<PAGE>
 
                                      -27-

     therein; and, subject to the limitation set forth immediately preceding
     this clause, will reimburse, as incurred, any reasonable and documented 
     out-of-pocket legal or other expenses reasonably incurred by the Issuers or
     any such director, officer or controlling person in connection with
     investigating or defending against or appearing as a third-party witness in
     connection with any such loss, claim, damage, liability or action in
     respect thereof. This indemnity agreement will be in addition to any
     liability that the Underwriters may otherwise have to the indemnified
     parties. The Underwriters will not, without the prior written consent of
     the Issuers, settle or compromise or consent to the entry of any judgment
     in any pending or threatened claim, action, suit or proceeding in respect
     of which indemnification from the Issuers may be sought hereunder (whether
     or not any of the Issuers or any person who controls any of the Issuers
     within the meaning of Section 15 of the Act or Section 20 of the Exchange
     Act is a party to such claim, action, suit or proceeding), unless such
     settlement, compromise or consent includes an unconditional release any of
     the Issuers and each such controlling person from all liability arising out
     of such claim, action, suit or proceeding.

          (c)   Promptly after receipt by an indemnified party under this
     Section 8 of notice of the commencement of any action, such indemnified
     party will, if a claim in respect thereof is to be made against the
     indemnifying party under this Section 8, notify the indemnifying party of
     the commencement thereof; but the omission so to notify the indemnifying
     party will not relieve it from any liability which it may have to any
     indemnified party otherwise than under this Section 8 except to the extent
     that such omission results in the forfeiture by the indemnifying party of
     substantial rights and defenses. In case any such action is brought against
     any indemnified party, and it notifies the indemnifying party of the
     commencement thereof, the indemnifying party will be entitled to
     participate therein and, to the extent that it may wish, jointly with any
     other indemnifying party similarly notified, to assume the defense thereof,
     with counsel reasonably satisfactory to such indemnified party; provided,
                                                                     --------
     however, that if the defendants in any such action include both the
     -------
     indemnified party and the indemnifying
<PAGE>
 
                                      -28-

     party and the indemnified party shall have reasonably concluded that there
     may be one or more legal defenses available to it and/or other indemnified
     parties that are different from or in addition to those available to any
     such indemnifying party such that representation of both the indemnified
     parties and the indemnifying parties by the same counsel is inappropriate
     then the indemnifying parties shall not have the right to direct the
     defense of such action on behalf of such indemnified party or parties and
     such indemnified party or parties shall have the right to select separate
     counsel to defend such action on behalf of such indemnified party or
     parties. After notice from the indemnifying party to such indemnified party
     of its election so to assume the defense thereof and approval by such
     indemnified party of counsel appointed to defend such action, the
     indemnifying party will not be liable to such indemnified party under this
     Section 8 for any legal or other expenses, other than reasonable and
     documented out-of-pocket costs of investigation, subsequently incurred by
     such indemnified party in connection with the defense thereof, unless (i)
     the indemnified party shall have employed separate counsel in accordance
     with the proviso to the immediately preceding sentence (it being
     understood, however, that in connection with such action the indemnifying
     party shall not be liable for the expenses of more than one separate
     counsel (in addition to local counsel) in any one action or separate but
     substantially similar actions in the same jurisdiction arising out of the
     same general allegations or circumstances, designated by the Underwriters
     in the case of paragraph (a) of this Section 8 or Alliance in the case of
     paragraph (b) of this Section 8, representing the indemnified parties under
     such paragraph (a) or paragraph (b), as the case may be, who are parties to
     such action or actions) or (ii) the indemnifying party has authorized in
     writing the employment of counsel for the indemnified party at the expense
     of the indemnifying parties. After such notice from the indemnifying
     parties to such indemnified party (so long as the indemnified party shall
     have informed the indemnifying parties of such action in accordance with
     this Section 8 on a timely basis prior to the indemnified party seeking
     indemnification hereunder), the indemnifying parties will not be liable for
     the costs and expenses of any settlement of such action 
<PAGE>
 
                                      -29-

     effected by such indemnified party without the consent of the indemnifying
     party, unless such indemnified party waived its rights under this Section
     8, in which case the indemnified party may effect such a settlement without
     such consent.

        (d)   In circumstances in which the indemnity agreement provided for in
     the preceding paragraphs of this Section 8 is unavailable or insufficient
     to hold harmless an indemnified party in respect of any losses, claims,
     damages or liabilities (or actions in respect thereof), each indemnifying
     party, in order to provide for just and equitable contribution, shall
     contribute to the amount paid or payable by such indemnified party as a
     result of such losses, claims, damages or liabilities (or actions in
     respect thereof) in such proportion as is appropriate to reflect (i) the
     relative benefits received by the indemnifying party or parties on the one
     hand and the indemnified party on the other from the offering of the
     Securities or (ii) if the allocation provided by the foregoing clause (i)
     is not permitted by applicable law, not only such relative benefits but
     also the relative fault of the indemnifying party or parties on the one
     hand and the indemnified party on the other in connection with the
     statements or omissions or alleged statements or omissions that resulted in
     such losses, claims, damages or liabilities (or actions in respect
     thereof). The relative benefits received by the Issuers on the one hand and
     the Underwriters on the other shall be deemed to be in the same proportion
     as the total proceeds from the offering of the Securities (before deducting
     expenses other than underwriting discounts and commissions) received by the
     Issuers bear to the total underwriting discounts and commissions received
     by the Underwriters. The relative fault of the parties shall be determined
     by reference to, among other things, whether the untrue or alleged untrue
     statement of a material fact or the omission or alleged omission to state a
     material fact relates to information supplied by the Issuers on the one
     hand, or the Underwriters on the other, the parties' relative intent,
     knowledge, access to information and opportunity to correct or prevent such
     statement or omission, and any other equitable considerations appropriate
     in the circumstances. The Issuers and the Underwriters agree that it would
     not be equitable if the
<PAGE>
 
                                      -30-

     amount of such contribution were determined by pro rata or per capita
     allocation (even if the Issuers on the one hand and the Underwriters on the
     other hand were treated as one entity for such purpose) or by any other
     method of allocation that does not take into account the equitable
     considerations referred to in the first sentence of this paragraph (d).
     Notwithstanding any other provision of this paragraph (d), the Underwriters
     shall not be obligated to make contributions hereunder that in the
     aggregate exceed the total underwriting discounts and commissions received
     by the Underwriters under this Agreement, less the aggregate amount of any
     damages that the Underwriters have otherwise been required to pay by reason
     of the untrue or alleged untrue statements or the omissions or alleged
     omissions to state a material fact, and no person guilty of fraudulent
     misrepresentation (within the meaning of Section 11(f) of the Act) shall be
     entitled to contribution from any person who was not guilty of such
     fraudulent misrepresentation.  For purposes of this paragraph (d), each
     person, if any, who controls any of the Underwriters within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act shall have the same
     rights to contribution as the Underwriters, and each director and each
     officer of the Issuers who signed the Registration Statement and each
     person, if any, who controls the Issuers within the meaning of Section 15
     of the Act or Section 20 of the Exchange Act shall have the same rights to
     contribution as the Issuers.

          9.    Survival Clause.  The respective representations, warranties, 
                ---------------
agreements, covenants, indemnities and other statements of the Issuers, their
officers and the Underwriters set forth in this Agreement or made by or on
behalf of them, respectively, pursuant to this Agreement shall remain in full
force and effect, regardless of (i) any investigation made by or on behalf of
the Issuers, any of their officers or directors, the Underwriters or any
controlling person referred to in Section 8 hereof and (ii) delivery of and
payment for the Securities, and shall be binding upon and shall inure to the
benefit of, any successors, assigns, heirs, personal representatives of the
Issuers, the Issuers, the Underwriters and indemnified parties referred to in
Section 8 hereof. The respective agreements, covenants, indemnities and other
statements set 
<PAGE>
 
                                      -31-

forth in Sections 6 and 8 hereof shall remain in full force and effect,
regardless of any termination or cancellation of this Agreement.

          10.    Termination.  (a)  This Agreement may be terminated in the sole
                 -----------
discretion of the Underwriters by notice to Alliance given in the event that the
Issuers shall have failed, refused or been unable to satisfy all conditions on

              Form of Opinion of O'Sullivan Graev & Karabell, LLP
              ---------------------------------------------------

          1.  To the best of our knowledge, there is no action, suit, proceeding
or investigation pending or threatened against or affecting any of Alliance or
the Guarantors, any of their respective subsidiaries or any of their respective
properties or assets in any court or before any governmental authority or
arbitration board or tribunal that seeks to restrain, enjoin, prevent the
consummation of or otherwise challenge any of the Transactions.

          2.  Assuming due authorization, execution and delivery by Alliance and
the Guarantors, the Indenture is the valid and legally binding agreement of
Alliance and each of the Guarantors, enforceable against Alliance and each of
the Guarantors in accordance with its terms, except that the enforcement thereof
may be subject to (i) bankruptcy, insolvency, reorganization, moratorium or
other similar laws now or hereafter in effect relating to creditors' rights
generally and (ii) general principles of equity and the discretion of the court
before which any proceeding therefor may be brought (regardless of whether such
enforcement is considered in a proceeding in equity or at law).

          3.  Assuming due authorization, execution and delivery by Alliance,
the Notes will conform in all material respects to the description thereof in
the Registration Statement and will be the legally valid and binding obligations
of Alliance, enforceable against Alliance in accordance with their terms, except
that the enforcement thereof may be subject to (i) bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally and (ii) general principles of equity
and the discretion of the court before which any proceeding therefor may be
brought (regardless of whether such enforcement is considered in a proceeding in
equity or at law).
<PAGE>
 
                                      -2-

          4.  Assuming due authorization, execution and delivery by the
Guarantors, the Guarantees will conform in all material respects to the
description thereof in the Registration Statement and will be the legally valid
and binding obligations of each of the Guarantors, enforceable against each of
the Guarantors in accordance with their terms, except that the enforcement
thereof may be subject to (i) bankruptcy, insolvency, reorganization, moratorium
or other similar laws now or hereafter in effect relating to creditors' rights
generally and (ii) general principles of equity and the discretion of the court
before which any proceeding therefor may be brought (regardless of whether such
enforcement is considered in a proceeding in equity or at law).

          5.  To the best of our knowledge, no consent, approval, authorization
or order of, or filing with any or governmental entity or body is required for
the issuance and sale of the Securities by Alliance and the Guarantors pursuant
to the Underwriting Agreement or pursuant to the Indenture, except (i) such as
have been obtained or made under the Act or the Trust Indenture Act or
otherwise, and (ii) such as may be required under state securities laws in
connection with the purchase and distribution of the Securities by the
Underwriters.

          6.  The Indenture has been duly qualified under the Trust Indenture
Act.

          7.  The Registration Statement has become effective under the Act and,
to the best of our knowledge, no stop order suspending the effectiveness of the
Registration Statement has been issued under the Act and no proceedings therefor
have been initiated by the Commission. Any required filing of the Prospectus
pursuant to Rule 424(b) under the Act has been made in accordance with Rules
424(b) and 430A under the Act.

          8.  The Registration Statement and the Prospectus comply as to form in
all material respects with the applicable requirements for registration
statements on Form S-2 under the Act, the Trust Indenture Act and the rules and
regulations of the Commission thereunder; it being understood, however, that we
express no opinion with respect to the financial statements, 
<PAGE>
 
                                      -3-

schedules and other financial and statistical data included in or omitted from
the Registration Statement or Prospectus.

          9.  To the best of our knowledge, there are no contracts or documents
of a character required to be described in the Registration Statement or
Prospectus or to be filed as exhibits to the Registration Statement that are not
described or filed as required.

          10.  The Transactions conform in all material respects to the
descriptions thereof in the Prospectus.

          11.  Neither the Company nor any of its subsidiaries is subject to
registration and regulation as an "investment company" or a company "controlled
by" and "investment company" within the meaning of the Investment Company Act
and the rules and regulations of the Commission thereunder.

          12.  Neither the issuance or sale of the Notes nor the application of
the net proceeds thereof as set forth in the Prospectus will violate Regulation
G, T, U or X of the Board of Governors of the Federal Reserve System.

          In addition, we have participated in conferences with officers and
other representatives of Alliance and the Guarantors, representatives of the
independent public accountants for Alliance and the Guarantors and your
representatives, at which the contents of the Registration Statement and the
Prospectus and related matters were discussed and, although we are not passing
upon, and do not assume any responsibility for, the accuracy, completeness or
fairness of the statements contained in the Registration Statement or the
Prospectus and have not made any independent check or verification thereof,
during the course of such participation (relying as to materiality to a large
extent upon the statements of officers and other representatives of Alliance and
the Guarantors), no facts came to our attention that caused us to believe that
the Registration Statement, at the time it became effective, contained an untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
that the Prospectus, as 
<PAGE>
 
                                      -4-

of its date or as of the Closing Date, contained or contains an untrue statement
of a material fact or omitted or omits to state a material fact necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; it being understood that we express no opinion with
respect to the financial statements, schedules and other financial and
statistical data included in or omitted from the Registration Statement or the
Prospectus or with respect to the Form T-1.

                                                                       ---------

                     Form of Opinion of Irell & Manella LLP
                     --------------------------------------

          1.  Each of Alliance, Alliance of Ohio, Inc. and Alliance of Michigan,
Inc. (collectively, the "Delaware Companies") are corporations duly organized,
validly existing and in good standing under the laws of the State of Delaware
with corporate power and authority to own or lease their properties and to
conduct their businesses as now conducted as described in each Prospectus.

          2.  Each of Alliance and the Guarantors has the corporate power and
authority to execute, deliver and perform its respective obligations under the
Underwriting Agreement, the Indenture and the Securities and to issue the
Securities to be issued by it pursuant to the Indenture.

          3.  The Indenture has been duly authorized, executed and delivered by
the Delaware Companies.

          4.  The Notes have been duly and validly authorized by Alliance for
issuance.

          5.  The Guarantees have been duly authorized by each of Alliance
Imaging of Ohio, Inc. and Alliance Imaging of Michigan, Inc.

          6.  The Underwriting Agreement has been duly authorized, executed and
delivered by the Delaware Companies; the execution and delivery of the
Underwriting Agreement, the Indenture and the Securities by Alliance and the
Guarantors, and the issuance and sale of the Securities pursuant to the
Underwriting Agreement and the performance of the Transactions do not and will
not conflict with or constitute or result in a breach or a default under (or an
event which with notice or passage of time or both would constitute a default
under) or violation of or cause an acceleration of any obligation under, or on
any properties or assets of Alliance or any Guarantor with respect to (i) the
terms or provisions of any Contract set 
<PAGE>
 
                                      -2-

forth as an exhibit to such counsel's opinion, except for any such conflict,
breach, violation, default or event which would not, individually or in the
aggregate, have a Material Adverse Effect, or (ii) the certificate of
incorporation or bylaws of the Delaware Companies, or (iii) any statute, rule or
regulation known to such counsel to be of general applicability to, or any
judgment, decree or order known to such counsel to be applicable to, Alliance or
any Guarantor or any of their respective properties or assets, except for any
such conflict, breach or violation which would not, individually or in the
aggregate, have a Material Adverse Effect.

          7.  To the best of our knowledge, there are no contracts or documents
of a character required to be described in the Registration Statement or
Prospectus or to be filed as exhibits to the Registration Statement that are not
described or filed as required.

          In addition, we have participated in conferences with officers and
other representatives of Alliance and the Guarantors, representatives of the
independent public accountants for Alliance and the Guarantors and your

compliance with Section 4.04 and (y) immediately before and immediately after
giving effect to such designation, no Default or Event of Default shall have
occurred and be continuing. Any such designation by the Board of Directors shall
be evidenced to the Trustee by promptly filing with the Trustee a copy of the
Board Resolution giving effect to such designation and an officers' certificate
certifying that such designation complied with the foregoing provisions.

                                THE SECURITIES

SECTION 2.01.  Form and Dating.
               --------------- 

          The Fixed Rate Notes and the Trustee's certificate of authentication
shall be substantially in the form of Exhibit A and the Floating Rate Notes and
the Trustee's certificate of authentication shall be substantially in the form
of Exhibit B.  The Securities may have notations, legends or endorsements
required by law, stock exchange rule or usage.  The Company and the Trustee
shall approve the form of the Securities and any notation, legend or endorsement
on them.  Each Security shall be dated the date of its issuance and show the
date of its authentication.  Each Security shall have an executed Guarantee from
each of the Guarantors endorsed thereon substantially in the form of Exhibit C.
<PAGE>
 
                                      -33-

          The terms and provisions contained in the Securities and the
Guarantees shall constitute, and are hereby expressly made, a part of this
Indenture and, to the extent applicable, the Company, the Guarantors and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

SECTION 2.02.  Execution and Authentication.
               ---------------------------- 

          Two Officers, or an Officer and an Assistant Secretary, shall sign, or
one Officer shall sign and one Officer or an Assistant Secretary (each of whom
shall, in each case, have been duly authorized by all requisite corporate
actions) shall attest to, the Securities for the Company and the Guarantees for
each of the Guarantors by manual or facsimile signature.

          If an Officer whose signature is on a Security or Guarantee, as the
case may be, was an Officer at the time of such execution but no longer holds
that office at the time the Trustee authenticates the Security, the Security
shall nevertheless be valid.

          A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security.  The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

          The Trustee shall authenticate (i) Fixed Rate Notes for original issue
on the Issue Date in the aggregate principal amount of $125,000,000 and (ii)
Floating Rate Notes for original issue on the Issue Date in the aggregate
principal amount of $40,000,000, upon a written order of the Company in the form
of an Officers' Certificate.  In addition, the Trustee shall authenticate
Securities for original issue after the Issue Date in the aggregate principal
amount of up to $100,000,000 upon a written order of the Company in the form of
an Officers' Certificate.  Each such Officers' Certificate shall specify the
amount of Securities to be authenticated, the date on which the Securities are
to be authenticated and whether the Securities are to be Fixed Rate Notes or
Floating Rate Notes.  Such Securities 
<PAGE>
 
                                      -34-

shall initially be in the form of one or more Global Securities, which (i) shall
represent, and shall be denominated in an amount equal to the aggregate
principal amount of, the Securities to be issued, (ii) shall be registered in
the name of the Depository for such Global Security or Securities or its
nominee, (iii) shall be delivered by the Trustee to the Depository or pursuant
to the Depository's instruction and (iv) shall bear a legend substantially to
the following effect: "Unless and until this Global Security is exchanged in
whole or in part for the individual Securities represented hereby, this Global
Security may not be transferred except as a whole by the Depository to a nominee
of the Depository or by a nominee of the Depository to the Depository or by a
Depository or any such nominee to a successor Depository or a nominee of a
successor Depository." The aggregate principal amount of Securities outstanding
at any time may not exceed $265,000,000, except as provided in Section 2.07.

          The Trustee may appoint an authenticating agent reasonably acceptable
to the Company to authenticate Securities.  Unless otherwise provided in the
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so.  Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent.  An authenticating agent has the
same rights as an Agent to deal with the Company and Affiliates of the Company.

          The Securities shall be issuable only in registered form without
coupons in denominations of $1,000 and integral multiples thereof.
SECTION 2.03.  Registrar and Paying Agent.
               -------------------------- 

          The Company shall maintain an office or agency in the Borough of
Manhattan, The City of New York, where (a) Securities may be presented or
surrendered for registration of transfer or for exchange ("Registrar"), (b)
                                                           ---------       
Securities may be presented or surrendered for payment ("Paying Agent") and (c)
                                                         ------------          
notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served.  The Company may also from time to time designate one
or more other offices 
<PAGE>
 
                                      -35-

or agencies where the Securities may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided, 
                                                                   --------
however, that no such designation or rescission shall in
- -------                                                 
any manner relieve the Company of its obligation to maintain an office or agency
in the Borough of Manhattan, The City of New York, for such purposes.  The
Company may act as its own Registrar or Paying Agent except that for the
purposes of Articles Three and Eight and Sections 4.15 and 4.16, neither the
Company nor any Affiliate of the Company shall act as Paying Agent.  The
Registrar shall keep a register of the Securities and of their transfer and
exchange.  The Company, upon notice to the Trustee, may have one or more co-
Registrars and one or more additional paying agents  reasonably acceptable to
the Trustee.  The term "Paying Agent" includes any additional paying agent.  The
                        ------------                                            
Company initially appoints the Trustee as Registrar and Paying Agent until such
time as the Trustee has resigned or a successor has been appointed.

          The Company shall enter into an appropriate agency agreement with any
Agent not a party to this Indenture, which agreement shall implement the
provisions of this Indenture that relate to such Agent.  The Company shall
notify the Trustee, in advance, of the name and address of any such Agent.  If
the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act
as such.

SECTION 2.04.  Paying Agent To Hold Assets in Trust.
               ------------------------------------ 

          The Company shall require each Paying Agent other than the Trustee to
agree in writing that, subject to Article Four and Article Twelve, each Paying
Agent shall hold in trust for the benefit of Holders or the Trustee all assets
held by the Paying Agent for the payment of principal of, or interest on, the
Securities (whether such assets have been distributed to it by the Company or
any other obligor on the Securities), and shall notify the Trustee of any
Default by the Company (or any other obligor on the Securities) in making any
such payment.  If the Company or a Subsidiary acts as Paying Agent, it shall
segregate such assets and hold them as a separate trust fund.  The Company at
any time may require a Paying Agent to 
<PAGE>
 
                                      -36-

distribute all assets held by it to the Trustee and account for any assets
disbursed and the Trustee may at any time during the continuance of any payment
Default, upon written request to a Paying Agent, require such Paying Agent to
distribute all assets held by it to the Trustee and to account for any assets
distributed. Upon distribution to the Trustee of all assets that shall have been
delivered by the Company to the Paying Agent, the Paying Agent shall have no
further liability for such assets.

SECTION 2.05.  Holder Lists.
               ------------ 

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders.  If the Trustee is not the Registrar, the Company shall furnish to the
Trustee on or before each Interest Payment Date and at such other times as the
Trustee may request in writing a list in such form and as of such date as the
Trustee may reasonably require of the names  and addresses of Holders, which
list may be conclusively relied upon by the Trustee.

SECTION 2.06.  Transfer and Exchange.
               --------------------- 

          (a)  When Securities are presented to the Registrar or a co-Registrar
with a request to register the transfer of such Securities or to exchange such
Securities for an equal principal amount of Securities of other authorized
denominations, the Registrar or co-Registrar shall register the transfer or make
the exchange as requested if its requirements for such transaction are met;
provided, however, that the Securities surrendered for transfer or exchange
- --------  -------                                                          
shall be duly endorsed or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Registrar or co-Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.  To
permit registrations of transfers and exchanges, the Company shall execute and
the Trustee shall authenticate Securities at the Registrar's or co-Registrar's
request.  No service charge shall be made for any registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
transfer tax or 
<PAGE>
 
                                      -37-

similar governmental charge payable in connection therewith (other than any such
transfer taxes or similar governmental charge payable upon exchanges or
transfers pursuant to Sections 2.02, 2.10, 3.06, 4.15, 4.16 or 9.06). The
Registrar or co-Registrar shall not be required to register the transfer of or
exchange of any Security (i) during a period beginning at the opening of
business 15 days before the mailing of a notice of redemption of Securities and
ending at the close of business on the day of such mailing, (ii) selected for
redemption in whole or in part pursuant to Article Three, except the unredeemed
portion of any Security being redeemed in part, and (iii) during a Change of
Control Offer or an Net Proceeds Offer if such Security is tendered pursuant to
such Change of Control Offer or Net Proceeds Offer and not withdrawn. A Global
Security may be transferred, in whole but not in part, in the manner provided in
this Section 2.06(a), only to a nominee of the Depository for such Global
Security, or to the Depository, or a successor Depository for such Global
Security selected or approved by the Company, or to a nominee of such successor
Depository.

          (b)  If at any time the Depository for the Global Security or
Securities notifies the Company that it is unwilling or unable to continue as
Depository for such Global Security or Securities or the Company becomes aware
that the Depository has ceased to be a clearing agency registered under the
Exchange Act, the Company shall appoint a successor Depository with respect to
such Global Security or Securities.  If a successor Depository for such Global
Security or Securities has not been appointed within 120 days after the Company
receives such notice or becomes aware of such ineligibility, the Company shall
execute, and the Trustee, upon receipt of an Officers' Certificate for the
authentication and delivery of Securities, shall authenticate and deliver,
Securities in definitive form, in an aggregate principal amount at maturity
equal to the principal amount at maturity of the Global Security representing
such Securities, in exchange for such Global Security.  The Company shall
reimburse the Registrar, the Depository and the Trustee for expenses they incur
in documenting such exchanges and issuances of Securities in definitive form.
<PAGE>
 
                                      -38-

          The Company may at any time and in its sole discretion determine that
the Securities shall no longer be represented by such Global Security or
Securities.  In such event the Company will execute, and the Trustee, upon
receipt of a written order for the authentication and delivery of individual
Securities in exchange in whole or in part for such Global Security or
Securities, will authenticate and deliver individual Securities in definitive
form in an aggregate principal amount equal to the principal amount of such
Global Security or Securities in exchange for such Global Security or
Securities.

          In any exchange provided for in any of the preceding two paragraphs,
the Company will execute and the Trustee will authenticate and deliver
individual Securities in definitive registered form in authorized denominations.
Upon the exchange of a Global Security for individual Securities, such Global
Security shall be cancelled by the Trustee.  Securities issued in exchange for a
Global Security pursuant to this Section 2.06(b) shall be registered in such
names and in such authorized denominations as the Depository for such Global
Security, pursuant to instructions from its direct or indirect participants or
otherwise, shall instruct the Trustee.  The Trustee shall deliver such
Securities to the persons in whose names such Securities are so registered.

          None of the Company, the Trustee, any Paying Agent or the Registrar
will have any responsibility or liability for any aspect of the records relating
to or payments made on account of beneficial ownership interests of a Global
Security or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

SECTION 2.07.  Replacement Securities.
               ---------------------- 

          If a mutilated Security is surrendered to the Trustee or if the Holder
of a Security claims that the Security has been lost, destroyed or wrongfully
taken, the Company shall issue and the Trustee shall authenticate a replacement
Security if the Trustee's requirements are met.  If required by the Trustee or
the Company, such Holder must provide an indemnity bond or other indemnity,
sufficient in the judgment of both the 
<PAGE>
 
                                      -39-

Company and the Trustee, to protect the Company, the Trustee or any Agent from
any loss which any of them may suffer if a Security is replaced. The Company may
charge such Holder for its reasonable out-of-pocket expenses in replacing a
Security pursuant to this Section 2.07, including reasonable fees and expenses
of counsel.

          Every replacement Security is an additional obligation of the Company.

SECTION 2.08.  Outstanding Securities.
               ---------------------- 

          Securities outstanding at any time are all the Securities that have
been authenticated by the Trustee except those cancelled by it, those delivered
to it for cancellation and those described in this Section as not outstanding.
A Security does not cease to be outstanding because the Company, the Guarantors
or any of their respective Affiliates holds the Security.

          If a Security is replaced pursuant to Section 2.07 (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Security
is held by a bona fide purchaser.  A mutilated Security ceases to be outstanding
             ---- ----                                                          
upon surrender of such Security and replacement thereof pursuant to Section
2.07.  If the principal amount of any Security is considered paid under Section
4.01, it ceases to be outstanding and interest ceases to accrue.

          If on a Redemption Date or the Maturity Date the Paying Agent (other
than the Company or a Subsidiary) holds U.S. Legal Tender or U.S. Government
obligations sufficient to pay all of the principal and interest due on the
Securities payable on that date, then on and after that date such Securities
cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09.  Treasury Securities.
               ------------------- 

          In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, 
<PAGE>
 
                                      -40-

waiver or consent, Securities owned by the Company, any of its Subsidiaries or
any of their respective Affiliates shall be disregarded, except that, for the
purposes of determining whether the Trustee shall be protected in relying on any
such direction, waiver or consent, only Securities that the Trustee knows or has
reason to know are so owned shall be disregarded.

SECTION 2.10.  Temporary Securities.
               -------------------- 

          Until definitive Securities are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Securities.  Temporary
Securities shall be substantially in the form of definitive Securities but may
have variations that the Company considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate definitive Securities in exchange for temporary Securities.  Until
such exchange, temporary Securities shall be entitled to the same rights,
benefits and privileges as definitive Securities.  Notwithstanding the
foregoing, so long as the Securities are represented by a Global Security, such
Global Security may be in typewritten form.

SECTION 2.11.  Cancellation.
               ------------ 

          The Company at any time may deliver Securities to the Trustee for
cancellation.  The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for transfer, exchange or payment.  The
Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent
(other than the Company or a Subsidiary), and no one else, shall cancel and, at
the written direction of the Company, shall dispose of all Securities
surrendered for transfer, exchange, payment or cancellation.  Subject to Section
2.07, the Company may not issue new Securities to replace Securities that it has
paid or delivered to the Trustee for cancellation.  If the Company or any
Guarantor shall acquire any of the Securities, such acquisition shall not
operate as a redemption or satisfaction of the Indebtedness represented by such
Securities unless and until the same are surrendered to the Trustee for
cancellation pursuant to this Section 2.11.
<PAGE>
 
                                      -41-

SECTION 2.12.  Defaulted Interest.
               ------------------ 

          If the Company defaults in a payment of interest on the Securities, it
shall, unless the Trustee fixes another record date pursuant to Section 6.10,
pay the defaulted interest, plus (to the extent lawful) any interest payable on
the defaulted interest, in any lawful manner.  The Company may pay the defaulted
interest to the persons who are Holders on a subsequent special record date,
which date shall be the fifteenth day next preceding the date fixed by the
Company for the payment of defaulted interest or the next succeeding Business
Day if such date is not a Business Day.  At least 15 days before any such
subsequent special record date, the Company shall mail to each Holder, with a
copy to the Trustee, a notice that states the subsequent special record date,
the payment date and the amount of defaulted interest, and interest payable on
such defaulted interest, if any, to be paid.

SECTION 2.13.  CUSIP Number.
               ------------ 

          The Company in issuing the Securities may use a "CUSIP" number, and if
so, the Trustee shall use the CUSIP number in notices of redemption or exchange
as a convenience to Holders; provided, however, that any such notice may state
                             --------  -------                                
that no representation is made as to the correctness or accuracy of the CUSIP
number printed in the notice or on the Securities, and that reliance may be
placed only on the other identification numbers printed on the Securities.

                                 ARTICLE THREE

                                  REDEMPTION

SECTION 3.01.  Notices to Trustee.
               ------------------ 

          If the Company elects to redeem Securities pursuant to Paragraph 6 or
Paragraph 7 of the Securities, it shall notify the Trustee in writing of the
Redemption Date, the Redemption Price and the principal amount of Securities to
be redeemed.  
<PAGE>
 
                                      -42-

The Company shall give notice of redemption to the Paying Agent and Trustee at
least 30 days but not more than 60 days before the Redemption Date (unless a
shorter notice shall be agreed to by the Trustee in writing), together with an
Officers' Certificate stating that such redemption will comply with the
conditions contained herein.

SECTION 3.02.  Selection of Securities To Be Redeemed.
               -------------------------------------- 

          In the event that less than all of the Fixed Rate Notes or Floating
Rate Notes are to be redeemed at any time, selection of such Securities for
redemption will be made by the Trustee in compliance with the requirements of
the principal national securities exchange, if any, on which such Securities are
listed or, if such Securities are not then listed on a national securities
exchange, on a pro rata basis, by lot or by such method as the Trustee shall
               --- ----                                                     
deem fair and appropriate; provided, however, that no Securities of a principal

          At least 30 days but not more than 60 days before a Redemption Date,
the Company shall mail a notice of redemption by first class mail, postage
prepaid, to each Holder whose Securities are to be redeemed at its registered
address.  At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense.  Each notice for
redemption shall identify the Securities to be redeemed and shall state:

             (1)  the Redemption Date;

             (2) the Redemption Price and the amount of accrued interest, if
     any, to be paid;
<PAGE>
 
                                      -43-

             (3) the name and address of the Paying Agent;

             (4) that Securities called for redemption must be surrendered to
     the Paying Agent to collect the Redemption Price plus accrued interest, if
     any;

             (5) that, unless the Company defaults in making the redemption
     payment, interest on Securities called for redemption ceases to accrue on
     and after the Redemption Date, and the only remaining right of the Holders
     of such Securities is to receive payment of the Redemption Price upon
     surrender to the Paying Agent of the Securities redeemed;

             (6) if any Security is being redeemed in part, the portion of the
     principal amount of such Security to be redeemed and that, after the
     Redemption Date, and upon surrender of such Security, a new Security or
     Securities in aggregate principal amount equal to the unredeemed portion
     thereof will be issued;

             (7) if fewer than all the Securities are to be redeemed, the
     identification of the particular Securities (or portion thereof) to be
     redeemed, as well as the aggregate principal amount of Securities to be
     redeemed and the aggregate principal amount of Securities to be outstanding
     after such partial redemption; and

             (8) the Paragraph of the Securities pursuant to which the
     Securities are to be redeemed.

          The notice, if mailed in a manner herein provided, shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice.  In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Security designated for redemption in whole or
in part shall not affect the validity of the proceedings for the redemption of
any other Security.

SECTION 3.04.  Effect of Notice of Redemption.
               ------------------------------ 

          Once notice of redemption is mailed in accordance with Section 3.03,
Securities called for redemption become due and payable on the Redemption Date
and at the Redemption Price  plus accrued interest, if any.  Upon surrender to
the Trustee or Paying Agent, such Securities called for redemption shall be paid
at the Redemption Price (which shall include accrued interest thereon to the
Redemption Date), but installments of interest, the maturity of which is on or
prior to the Redemption Date, shall be payable to Holders of record at the close
of business on the relevant Record Dates.

SECTION 3.05.  Deposit of Redemption Price.
               --------------------------- 

          On or before 11:00 a.m New York time on the Redemption Date, the
Company shall deposit with the Paying Agent U.S. Legal Tender sufficient to pay
the Redemption Price plus accrued interest, if any, of all Securities to be
redeemed on that date.

          If the Company complies with the preceding paragraph, then, unless the
Company defaults in the payment of such Redemption Price plus accrued interest,
if any, interest on the Securities to be redeemed will cease to accrue on and
after the applicable Redemption Date, whether or not such Securities are
presented for payment.

SECTION 3.06.  Securities Redeemed in Part.
               --------------------------- 

          Upon surrender of a Security that is to be redeemed in part only, the
Trustee shall upon written instruction from the Company authenticate for the
Holder a new Security or Securities in a principal amount equal to the
unredeemed portion of the Security surrendered.

interest on the Securities shall be considered paid on the date it is due if the

give prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency.  If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the address of the Trustee set forth in Section 11.02.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations.  The
Company will give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

          The Company hereby initially designates the Corporate Trust Office of

from an unaffiliated party.

shall purchase, on a Business Day (the "Change of Control Payment Date") as
                                        ------------------------------     
described below, all of the then outstanding Securities at a purchase price

all other such Senior Debt and to repay the Indebtedness owed to each lender
which has accepted such offer or (ii) obtain the requisite consents under the

          (c)  Within 30 days following the date upon which a Change of Control
occurs (the "Change of Control Date"), the Company shall send, by first class

     any Security accepted for payment pursuant  to the Change of Control Offer
     shall cease to accrue interest after the Change of Control Payment Date;

     the Security completed, to the Paying Agent at the address specified in the
     notice prior to the close of business on the Change of Control Payment
     Date;

             (6) that Holders will be entitled to withdraw their election if the

     Change of Control Payment Date, a telegram, telex, facsimile transmission
     or letter setting forth the name of the Holder, the principal amount of the
     Securities the Holder delivered for purchase and a statement that such
     Holder is withdrawing his election to have such Security purchased;

             (7) that Holders whose Securities are purchased only in part will
     be issued new Securities in a principal amount equal to the unpurchased
     portion of the Securities surrendered; and

             (8) the circumstances and relevant facts regarding such Change of
     Control.

          On or before the Change of Control Payment Date, the Company shall (i)
accept for payment Securities or portions thereof tendered pursuant to the
Change of Control Offer, (ii) deposit with the Paying Agent U.S. Legal Tender
sufficient to pay the purchase price plus accrued interest, if any, of all
Securities so tendered and (iii) deliver to the Trustee Securities so accepted

by the Company or the Restricted Subsidiary, as the case may be, from such Asset
Sale shall be in the form of cash or Cash Equivalents and is received at the

                          --------

transferee of any such assets, and (b) any notes or other obligations received
by the Company or any such Restricted Subsidiary from such transferee that are

Asset Sale, the Company shall apply, or cause such Restricted Subsidiary to
apply, the Net Cash Proceeds relating to such Asset Sale within 360 days of
receipt thereof either (A) to prepay any Senior Debt or Guarantor

under such revolving credit facility, (B) to make an Investment in properties
and assets that replace the properties and assets that were the subject of such
Asset Sale or in properties and assets that will be used in the business of the
Company and its Restricted Subsidiaries as existing on the Issue Date or in
businesses the same, similar or reasonably related thereto ("Replacement

- ------
foregoing clauses (iii)(A) and (iii)(B). On the 361st day after an Asset Sale or
such earlier date, if any, as the Board of Directors of the Company or of such
Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to
such Asset Sale as set forth in clauses (iii)(A), (iii)(B) and (iii)(C) of the
next preceding sentence (each, a "Net Proceeds Offer Trigger Date"), such 
                                  -------------------------------    
aggregate amount of Net Cash Proceeds which have not been applied on or before
such Net Proceeds Offer Trigger Date as permitted in clauses (iii)(A), (iii)(B)

amount of Securities equal to the Net Proceeds Offer Amount at a price equal to
100% of the principal amount of the Securities to be purchased, plus accrued and
unpaid interest thereon, if any, to the date of purchase; provided, however,
                                                          --------  -------

Restricted Subsidiary of the Company, as the case may be, in connection with any
Asset Sale is converted into or sold or otherwise disposed of for cash (other
than interest received with respect to any such non-cash consideration), then
such conversion or disposition shall be deemed to constitute an Asset Sale
hereunder and the Net Cash Proceeds thereof shall be applied in accordance with
this covenant.  The Company may defer the Net Proceeds Offer until there is an
aggregate unutilized Net Proceeds Offer Amount equal to or in excess of $5.0
million resulting from one or more Asset Sales (at which time, the entire
unutilized Net Proceeds Offer Amount, and not just the amount in excess of $5.0
million, shall be applied as required pursuant to this paragraph).

permitted by Section 5.01, the successor corporation shall be deemed to have
sold the properties and assets of the Company and its Restricted Subsidiaries
not so transferred for purposes of this covenant, and shall comply with the
provisions of this covenant with respect to such deemed sale as if it were an
Asset Sale. In addition, the fair market value of such properties and assets of
the Company or its Restricted Subsidiaries deemed to be sold shall be deemed to
be Net Cash Proceeds for purposes of this covenant.

          Notice of each Net Proceeds Offer pursuant to this Section 4.16 shall
be mailed or caused to be mailed, by first class mail, by the Company within 25
days following the applicable Net Proceeds Offer Trigger Date to all Holders at
their last registered addresses, with a copy to the Trustee.  A Net Proceeds
Offer shall remain open for a period of 20 Business Days or such longer period
as may be required by law.  The notice shall contain all instructions and

     Section 4.16 and that all Securities tendered will be accepted for payment;

     be required by applicable law);

             (3) that any Security not tendered will continue to accrue
     interest;

     to the Net Proceeds Offer shall cease to accrue interest after the Net
     Proceeds Offer Payment Date;

             (5) that Holders electing to have a Security purchased pursuant to
     the Net Proceeds Offer will be required to surrender the Security, with the
     form entitled "Option of Holder to Elect Purchase" on the reverse of the
     Security completed, to the Paying Agent at the address specified in the
     notice prior to the close of business on the Net Proceeds Offer Payment
     Date;

     Holder delivered for purchase and a statement that such Holder is
     withdrawing his election to have such Security purchased; and

             (7) that Holders whose Securities are purchased only in part will
     be issued new Securities in a principal amount at maturity equal to the

Net Proceeds Offer, (ii) deposit with the Paying Agent U.S. Legal Tender
sufficient to pay the purchase price, plus accrued interest, if any, of all
Securities to be purchased and (iii) deliver to the Trustee Securities so
accepted together with an Officers' Certificate stating the Securities or
portions thereof being purchased by the Company.  The Paying Agent shall
promptly mail to the Holders of Securities so accepted payment in an amount
equal to the purchase price, plus accrued interest, if any, thereon.  Any
Security not so accepted shall be promptly mailed by the Company to the Holder
thereof.  For purposes of this Section 4.16, the Trustee shall act as the Paying

Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Securities pursuant to a Net Proceeds Offer.  To the extent that
the provisions of any securities laws or regulations conflict with the
provisions of this Section 4.16, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under this Section 4.16 by virtue thereof.

               Senior Subordinated Debt.
               -------------------------

          The Company and the Guarantors shall not incur or suffer to exist
Indebtedness that is senior in right of payment to the Securities or the
Guarantees, as the case may be, and subordinate in right of payment by its terms
to any other Indebtedness of the Company or such Guarantor, as the case may be.

transactions, any property to any domestic Restricted Subsidiary that is not a
Guarantor, or if the Company or any of its Restricted Subsidiaries shall
organize, acquire or otherwise invest in another domestic Restricted Subsidiary
having total equity value in excess of $1.0 million, then such transferee or
acquired or other Restricted Subsidiary shall (i) execute and deliver to the
Trustee a supplemental indenture in form reasonably satisfactory to the Trustee
pursuant to which such Restricted Subsidiary shall unconditionally guarantee all
of the Company's obligations under the Securities and this Indenture on the

Counsel that such supplemental indenture has been duly authorized, executed and
delivered by such Restricted Subsidiary and constitutes a legal, valid, binding
and enforceable obligation of such Restricted Subsidiary.  Thereafter, such
Restricted Subsidiary shall be a Guarantor for all purposes of this Indenture.

released in accordance with the terms of the Guarantee and this Indenture in
connection with any transaction complying with the provisions of Section 4.16)
shall not, and the Company shall not cause or permit any Guarantor to,

SECTION 6.02.  Acceleration.
               ------------ 

          If an Event of Default (other than an Event of Default specified in
clause (f) or (g) of Section 6.01 above with respect to the Company) shall occur
and be continuing, the Trustee or the Holders of at least 25% in principal
amount of outstanding Securities may declare the principal of and accrued
interest on all the Securities to be due and payable by notice in writing to the
Company and the Trustee specifying the respective Event of Default and that it
is a "notice of acceleration" 
<PAGE>
 
                                      -70-

(the "Acceleration Notice"), and the same (i) shall become immediately due and
      -------------------                    
payable or (ii) if there are any amounts outstanding under the Credit Agreement,
shall become immediately due and payable upon the first to occur of an
acceleration under the Credit Agreement or 5 business days after receipt by the
Company and the Representative under the Credit Agreement of such Acceleration
Notice. If an Event of Default specified in clause (f) or (g) of Section 6.01
above with respect to the Company occurs and is continuing, then all unpaid
principal of, and premium, if any, and accrued and unpaid interest on all of 
the outstanding Securities shall ipso facto become and be immediately due and 
                                 ---- -----
payable without any declaration or other act on the part of the Trustee or any
Holder.

          At any time after a declaration of acceleration with respect to the
Securities as described in the preceding paragraph, the Holders of a majority in
principal amount of the Securities may rescind and cancel such declaration and
its consequences (i) if the rescission would not conflict with any judgment or
decree, (ii) if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of the
acceleration, (iii) to the extent the payment of such interest is lawful,
interest on overdue installments of interest and overdue principal, which has
become due otherwise than by such declaration of acceleration, has been paid,
(iv) if the Company has paid the Trustee its reasonable compensation and
reimbursed the Trustee for its expenses, disbursements and advances and (v) in
the event of the cure or waiver of an Event of Default of the type described in
clause (f) or (g) of Section 6.01, the Trustee shall have received an Officers'
Certificate and an Opinion of Counsel that such Event of Default has been cured
or waived.  No such rescission shall affect any subsequent Default or impair any
right consequent thereto.

SECTION 6.03.  Other Remedies.
               -------------- 

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of or interest on 
<PAGE>
 
                                      -71-

the Securities or to enforce the performance of any provision of the Securities
or this Indenture.

          The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Securityholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative to the
extent permitted by law.

SECTION 6.04.  Waiver of Past Defaults.
               ----------------------- 

          Subject to Sections 2.09, 6.07 and 9.02, the Holders of not less than
a majority in principal amount of the outstanding Securities by notice to the
Trustee may waive an existing Default or Event of Default and its consequences,
except a Default in the payment of principal of or interest on any Security as
specified in clauses (a) and (b) of Section 6.01.  The Company shall deliver to
the Trustee an Officers' Certificate stating that the requisite percentage of
Holders have consented to such waiver and attaching copies of such consents.
When a Default or Event of Default is waived, it is cured and ceases.

SECTION 6.05.  Control by Majority.
               ------------------- 

          The Holders of not less than a majority in principal amount of the
outstanding Securities may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on it.  Subject to Section 7.01, however, the Trustee may refuse
to follow any direction that conflicts with any law or this Indenture, that the
Trustee determines may be unduly prejudicial to the rights of another
Securityholder, or that may involve the Trustee in personal liability; provided
                                                                       --------
that the Trustee may take any other action deemed proper by the Trustee which is
not inconsistent with such direction.
<PAGE>
 
                                      -72-

          In the event the Trustee takes any action or follows any direction
pursuant to this Indenture, the Trustee shall be entitled to indemnification
satisfactory to it in its sole discretion against any loss or expense caused by
taking such action or following such direction.

SECTION 6.06.  Limitation on Suits.
               ------------------- 
                  A Securityholder may not pursue any remedy with respect to
this Indenture or the Securities unless:

             (1) the Holder gives to the Trustee written notice of a continuing
     Event of Default;

             (2) the Holder or Holders of at least 25% in principal amount of
     the outstanding Securities make a written request to the Trustee to pursue
     the remedy;

             (3) such Holder or Holders offer and, if requested, provide to the
     Trustee indemnity satisfactory to the Trustee against any loss, liability
     or expense;

             (4) the Trustee does not comply with the request within 45 days
     after receipt of the request and the offer and, if requested, the provision
     of indemnity; and

             (5) during such 45-day period the Holder or Holders of a majority
     in principal amount of the outstanding Securities do not give the Trustee a
     direction which, in the opinion of the Trustee, is inconsistent with the
     request.

          A Securityholder may not use this Indenture to prejudice the rights of
another Securityholder or to obtain a preference or priority over such other
Securityholder.

SECTION 6.07.  Rights of Holders To Receive Payment.
               ------------------------------------ 

          Notwithstanding any other provision of this Indenture, the right of
any Holder to receive payment of principal of and interest on a Security, on or
after the respective due dates expressed in such Security, or to bring suit for
the enforcement of any such payment on or after such respective 
<PAGE>
 
                                      -73-

dates, shall not be impaired or affected without the consent of the Holder.

SECTION 6.08.  Collection Suit by Trustee.
               -------------------------- 

          If an Event of Default in payment of principal or interest specified
in clause (a) or (b) of Section 6.01 occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company or any other obligor on the Securities for the whole amount of principal
and accrued interest and fees remaining unpaid, together with interest on
overdue principal and, to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate per annum
                                                                       --- -----
borne by the Securities and such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09.  Trustee May File Proofs of Claim.
               -------------------------------- 

          The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Securityholders allowed in any judicial proceedings relating to the Company, its
creditors or its property and shall be entitled and empowered to collect and
receive any monies or other property payable or deliverable on any such claims
and to distribute the same, and any Custodian in any such judicial proceedings
is hereby authorized by each Securityholder to make such payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Securityholders, to pay to the Trustee any amount due to it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agent and counsel, and any other amounts due the Trustee under
Section 7.07.  Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to or accept or adopt on behalf of any Securityholder
any plan of reorganization, arrangement, adjustment or composition affecting 
<PAGE>
 
                                      -74-

the Securities or the rights of any Holder thereof, or to authorize the Trustee
to vote in respect of the claim of any Securityholder in any such proceeding.

SECTION 6.10.  Priorities.
               ---------- 
          If the Trustee collects any money or property pursuant to this Article
Six, it shall pay out the money or property in the following order:

             First:  to the Trustee for amounts due under Section 7.07;

             Second:  to Holders for interest accrued on the Securities,
     ratably, without preference or priority of any kind, according to the
     amounts due and payable on the Securities for interest;

             Third:  to Holders for principal amounts due and unpaid on the
     Securities, ratably, without preference or priority of any kind, according
     to the amounts due and payable on the Securities for principal; and

             Fourth:  to the Company or, if applicable, the Guarantors, as their
     respective interests may appear.

          The Trustee, upon prior notice to the Company, may fix a record date
and payment date for any payment to Securityholders pursuant to this Section
6.10.

SECTION 6.11.  Undertaking for Costs.
               --------------------- 

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section 6.11 does not apply to a suit by the Trustee, a suit by a

Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than
10% in principal amount of the outstanding Securities.

          (a)  If a Default or an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture and use the same degree of care and skill in their exercise
as a prudent person would exercise or use under the circumstances in the conduct
of his or her own affairs.

          (b)  Except during the continuance of a Default or an Event of 
Default:
             (1) The Trustee need perform only those duties as are specifically

     or obligations shall be implied in this Indenture against the Trustee.

             (2) In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates (including Officers'
     Certificates) or opinions (including Opinions of Counsel) furnished to the
     Trustee and conforming to the requirements of this Indenture.  However, the
     Trustee shall examine the certificates and opinions to determine whether or
     not they conform to the requirements of this Indenture.

          (c)  Notwithstanding anything to the contrary herein, the Trustee may
not be relieved from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

          (d)  No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture or take any action at the request or direction of Holders
if it shall have reasonable grounds for believing that repayment of such funds

     the proper Person. The Trustee need not investigate any fact or matter
     stated in the document.

             (b)  Before the Trustee acts or refrains from acting, it may
     require an Officers' Certificate and an Opinion of Counsel, which shall

     on such certificate or opinion.

             (c)  The Trustee may act through its attorneys and agents and shall

     security or indemnity against the costs, expenses and liabilities which may
     be incurred therein or thereby.

             (g)  The Trustee shall not be bound to make any investigation into
     the facts or matters stated in any resolution, certificate (including any
     Officers' Certificate), statement, instrument, opinion (including any
     Opinion of Counsel), notice, request, direction, consent, order, bond,
     debenture, or other paper or document, but the Trustee, 
<PAGE>
 
                                      -78-

     in its discretion, may make such further inquiry or investigation into such

SECTION 7.05.  Notice of Default.

Trustee receives actual notice of such Default or Event of Default, the Trustee
shall mail to each Securityholder notice of the uncured Default or Event of
Default within 60 days after such Default or Event of Default occurs.  Except in
the case of a Default or an Event of Default in payment of principal of, or
interest on, any Security, including an accelerated payment and the failure to

          Within 60 days after each May 15, beginning with the first May 15

SECTION 7.07.  Compensation and Indemnity.

<PAGE>
 
                                      -80-

Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable disbursements, expenses and advances (including
reasonable fees and expenses of counsel) incurred or made by it in addition to
the compensation for its services, except any such disbursements, expenses and
advances as may be attributable to the Trustee's negligence, bad faith or
willful misconduct. Such expenses shall include the reasonable fees and expenses
of the Trustee's agents and counsel.

          The Company shall indemnify the Trustee and its agents, employees,
officers, stockholders and directors for, and hold them harmless against, any
loss, liability or expense incurred by them except for such actions to the
extent caused by any negligence, bad faith or willful misconduct on their part,
arising out of or in connection with the acceptance or administration of this
trust including the reasonable costs and expenses of defending themselves
against or investigating any claim or liability in connection with the exercise
or performance of any of the Trustee's rights, powers or duties hereunder.  The

Trustee shall cooperate in the defense.  The Trustee and its agents, employees,

counsel and the Company shall pay the reasonable fees and expenses of such
counsel; provided, however, that the Company will not be required to pay such
         --------  -------                                                   
fees and expenses if it assumes the Trustee's defense and there is no conflict
of interest between the Company and the Trustee and its agents, employees,
officers, stockholders and directors subject to the claim in connection with
such defense as reasonably determined by the Trustee.  The Company need not pay
for any settlement made without its written consent.  The Company need not
reimburse any expense or indemnify against any loss or liability to the extent
incurred by the Trustee through its negligence, bad faith or willful misconduct.
<PAGE>
 
                                      -81-

          To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a senior claim prior to the Securities against all money or
property held or collected by the Trustee, in its capacity as Trustee, except
assets or money held in trust to pay principal of or interest on particular
Securities.

          When the Trustee incurs expenses or renders services after an Event of

the compensation for such services shall be paid to the extent allowed under any
Bankruptcy Law.

SECTION 7.08.  Replacement of Trustee.
               ---------------------- 

          The Trustee may resign at any time by so notifying the Company in
writing.  The Holders of a majority in principal amount of the outstanding

             (2) the Trustee is adjudged a bankrupt or an insolvent;

             (3) a receiver or other public officer takes charge of the Trustee
     or its property; or

             (4) the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall notify each Holder of such
event and shall promptly appoint a successor Trustee. Within one year after the
successor Trustee takes office, the Holders of a majority in principal amount of
the Securities may appoint a successor Trustee to replace the successor Trustee

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Immediately after that,
the retiring Trustee shall

transfer, after payment of all sums then owing to the Trustee pursuant to
Section 7.07, all property held by it as Trustee to the successor Trustee,
subject to the Lien provided in Section 7.07, the resignation or removal of the
retiring Trustee shall become effective, and the successor Trustee shall have
all the rights, powers and duties of the Trustee under this Indenture. A
successor Trustee shall mail notice of its succession to each Securityholder.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in principal amount of the outstanding Securities may
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

          If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

          Notwithstanding replacement of the Trustee pursuant to this Section
7.08, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

otherwise eligible hereunder, be the successor Trustee; provided that such
                                                        --------

     sufficient without consideration of reinvestment of such interest, to pay
     principal of, premium, if any, and interest on the outstanding Securities
     to maturity or redemption; provided that the Trustee shall have been
                                --------

                                      -85-

     stating that all conditions precedent providing for or relating to the
     termination of the Company's obligations under the Securities and this
     Indenture have been complied with. Such Opinion of Counsel shall also state
     that such satisfaction and discharge does not result in a default under the
     Credit Agreement or any other agreement or instrument then known to such
     counsel that binds or affects the Company.

          Notwithstanding the foregoing paragraph, the Company's obligations in
Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02, 7.07, 8.05 and 8.06 shall survive

be deemed to have paid and discharged the entire Indebtedness represented by the
outstanding Securities, which shall thereafter be deemed to be "outstanding"
only for the purposes of Section 8.04 hereof and 
<PAGE>
 
                                      -86-

the other Sections of this Indenture referred to in (i) and (ii) below, and to
have satisfied all its other obligations under such Securities and this
Indenture (and the Trustee, on demand of and at the expense of the Company,
shall execute proper instruments acknowledging the same), and Holders of the
Securities and any amounts deposited under Section 8.03 hereof shall cease to be
subject to any obligations to, or the rights of, any holder of Senior Debt under

obligations in connection therewith and (iv) this Article Eight. Subject to
compliance with this Article Eight, the Company may exercise its option under
this paragraph (b) notwithstanding the prior exercise of its option under
paragraph (c) hereof.

          (c)  Upon the Company's exercise under paragraph (a) hereof of the
option applicable to this paragraph (c), the Company shall, subject to the
satisfaction of the conditions set forth in Section 8.03 hereof, be released
from its obligations under the covenants contained in Sections 4.03, 4.04 and
Sections 4.12 through 4.18 and Article Five hereof with respect to the

                         -------------------                            
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes hereunder (it being understood that such
Securities shall not be deemed outstanding for accounting purposes) and Holders
of the Securities and any amounts deposited under Section 8.03 hereof shall
cease to be subject to any obligations to, or the rights

such Covenant Defeasance means that, with respect to the outstanding Securities,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such covenant, whether
directly or indirectly, by reason of any reference elsewhere herein to any such
covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a Default or an Event of Default under Section 6.01(c) hereof, but,
except as specified above, the remainder of this Indenture and such Securities
shall be unaffected thereby. In addition, upon the Company's exercise under
paragraph (a) hereof of the option applicable to this paragraph (c), subject to
the satisfaction of the conditions set forth in Section 8.03 hereof, Sections
6.01(c), 6.01(d) and 6.01(e) shall not constitute Events of Default.

     income tax purposes as a result of such Legal Defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such Legal Defeasance had
     not occurred;

             (c)  in the case of an election under Section 8.02(c) hereof, the

     Defeasance had not occurred;

             (d)  no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the incurrence of Indebtedness all or a portion of
     the proceeds of which will be used to defease the Securities pursuant to
     this Article Eight concurrently with such incurrence) or insofar as

     creditors of the Company or others;

             (g)  the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions

     or insolvency of the Company between the date of deposit and the 91st day
     following the deposit and that no Holder is an insider of the Company,

request any U.S. Legal Tender or U.S. Government Obligations held by it as
provided in Section 8.03 hereof which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are in excess of the amount thereof that would
then be required to be deposited to effect an equivalent Legal Defeasance or
Covenant Defeasance.

SECTION 8.05.  Repayment to the Company.
               ------------------------ 

          Subject to this Article Eight, the Trustee and the Paying Agent shall
promptly pay to the Company upon request any excess U.S. Legal Tender or U.S.
Government Obligations held by them at any time and thereupon shall be relieved
from all liability with respect to such money.  The Trustee and the Paying Agent
shall pay to the Company upon request any money held by them for the payment of
principal or interest that remains unclaimed for two years; provided that the
                                                            --------         
Trustee or such Paying Agent, before being required to make any payment, may at
the expense of the Company cause to be published once in a newspaper of general
circulation in the City of New York or mail to each Holder entitled to such
money notice that such money remains unclaimed and that after a date specified
therein which 
<PAGE>
 
                                      -91-

shall be at least 30 days from the date of such publication or mailing any
unclaimed balance of such money then remaining will be repaid to the Company.
After payment to the Company, Holders entitled to such money must look to the
Company for payment as general creditors unless an applicable law designates
another Person.

SECTION 8.06.  Reinstatement.
               ------------- 

          If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender or U.S. Government Obligations in accordance with this Article Eight by
reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to this Article Eight until such time as the Trustee or Paying Agent is
permitted to apply all such U.S. Legal Tender or U.S. Government Obligations in
accordance with this Article Eight; provided that if the Company has made any
                                    --------                                 
payment of interest on or principal of any Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment from the U.S. Legal
Tender or U.S. Government Obligations held by the Trustee or Paying Agent.

SECTION 9.01.  Without Consent of Holders.
               -------------------------- 

          The Company, the Guarantors and the Trustee, together, may amend or
supplement this Indenture, the Securities or the Guarantees without notice to or
consent of any Securityholder:

             (1) to cure any ambiguity, defect or inconsistency;
<PAGE>
 
                                      -92-

             (2) to evidence the succession in accordance with Article Five
     hereof of another Person to the Company and the assumption by any such
     successor of the covenants of the Company herein and in the Securities;

             (3) to provide for uncertificated Securities in addition to or in

             (5) to comply with any requirements of the Commission in connection
     with the qualification of this Indenture under the TIA; or

             (6) to add or release any Guarantor pursuant to the terms of this
     Indenture;

provided that the Company has delivered to the Trustee an Opinion of Counsel and
- --------                                                                        
an Officers' Certificate, each stating that such amendment or supplement
complies with the provisions of this Section 9.01.

SECTION 9.02.  With Consent of Holders.
               ----------------------- 

          Subject to Section 6.07, the Company, the Guarantors and the Trustee,
together, with the written consent of the Holder or Holders of at least a
majority in aggregate principal amount of the outstanding Securities, may amend
or supplement this Indenture, the Securities or the Guarantees, without notice
to any other Securityholders.  Subject to Section 6.07, the Holder or Holders of
a majority in aggregate principal amount of the outstanding Securities may waive
compliance by the Company with any provision of this Indenture, the Securities
or the Guarantees without notice to any other Securityholder.  Without the
consent of each Securityholder affected, however, no amendment, supplement or
waiver, including a waiver pursuant to Section 6.04, may:
<PAGE>
 
                                      -93-

             (1) reduce the amount of Securities whose Holders must consent to
     an amendment, supplement or waiver;

             (2) reduce the rate of or change or have the effect of changing the
     time for payment of interest, including default interest, on any Security;

             (3) reduce the principal of or change or have the effect of
     changing the fixed maturity of any Security, or change the date on which
     any Securities may be subject to redemption or repurchase, or reduce the
     redemption or purchase price therefor;

             (4) make any Securities payable in money other than that stated in
     the Securities;

             (5) make any change in provisions of this Indenture protecting the
     right of each Holder to receive payment of principal of and interest on
     such Security on or after the due date thereof or to bring suit to enforce
     such payment, or permitting Holders of a majority in principal amount of
     the Securities to waive Defaults or Events of Default;

             (6) make any changes in Section 6.04, 6.07 or this Section 9.02;

             (7) modify or change any provision of this Indenture or the related
     definitions affecting the subordination or ranking of the Securities or any
     Guarantee, in a manner which adversely affects the Holders;

             (8) amend, modify or change in any material respect the obligation
     of the Company to make and consummate a Change of Control Offer in the
     event of a Change of Control or make and consummate a Net Proceeds Offer
     with respect to any Asset Sale that has been consummated or, modify any of
     the provisions or definitions with respect thereto; or
<PAGE>
 
                                      -94-

             (9) release any Guarantor from any of its obligations under its
     Guarantee or this Indenture otherwise than in accordance with the terms of
     this Indenture.

          It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment, supplement or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

          After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver.  Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture.

SECTION 9.03.  Effect on Senior Debt.
               --------------------- 

          No amendment of this Indenture shall adversely affect the rights of
any holder of Senior Debt or Guarantor Senior Debt under Article Ten or Article
Twelve, as the case may be, of this Indenture, without the consent of such
holder.

SECTION 9.04.  Compliance with TIA.
               ------------------- 

          From the date on which this Indenture is qualified under the TIA,
every amendment, waiver or supplement of this Indenture, the Securities or the
Guarantees shall comply with the TIA as then in effect.

SECTION 9.05.  Revocation and Effect of Consents.
               --------------------------------- 

          Until an amendment, waiver or supplement becomes effective, a consent
to it by a Holder is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if notation of the consent is not made on
any Security.  However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of his Security by notice to the Trustee
or the Company received before 
<PAGE>
 
                                      -95-

the date on which the Trustee receives an Officers' Certificate certifying that
the Holders of the requisite principal amount of Securities have consented (and
not theretofore revoked such consent) to the amendment, supplement or waiver.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver which record date shall be at least 30 days prior to the
first solicitation of such consent.  If a record date is fixed, then
notwithstanding the last sentence of the immediately preceding paragraph, those
Persons who were Holders at such record date (or their duly designated proxies),
and only those Persons, shall be entitled to revoke any consent previously
given, whether or not such Persons continue to be Holders after such record
date.  No such consent shall be valid or effective for more than 90 days after
such record date.

          After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder, unless it makes a change described in any of clauses
(1) through (9) of Section 9.02, in which case, the amendment, supplement or
waiver shall bind only each Holder of a Security who has consented to it and
every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder's Security; provided that any such waiver
                                                   --------                     
shall not impair or affect the right of any Holder to receive payment of
principal of and interest on a Security, on or after the respective due dates
expressed in such Security, or to bring suit for the enforcement of any such
payment on or after such respective dates without the consent of such Holder.

SECTION 9.06.  Notation on or Exchange of Securities.
               ------------------------------------- 

          If an amendment, supplement or waiver changes the terms of a Security,
the Company may require the Holder of the Security to deliver it to the Trustee.
The Company may place an appropriate notation on the Security about the changed
terms and return it to the Holder.  Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Security shall issue and the
Trustee shall authenticate a new 
<PAGE>
 
                                      -96-

Security that reflects the changed terms. Failure to make the appropriate
notation or issue a new Security shall not affect the validity and effect of
such amendment, supplement or waiver.

SECTION 9.07.  Trustee To Sign Amendments, Etc.
               ------------------------------- 

          The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article Nine; provided that the Trustee may, but
                                          --------                          
shall not be obligated to, execute any such amendment, supplement or waiver
which affects the Trustee's own rights, duties or immunities under this
Indenture.  The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel and an Officers' Certificate
each stating that the execution of any amendment, supplement or waiver
authorized pursuant to this Article Nine is authorized or permitted by this
Indenture and constituted the legal, valid and binding obligations of the
Company enforceable in accordance with its terms.  Such Opinion of Counsel shall
be at the expense of the Company.

                          SUBORDINATION OF SECURITIES

SECTION 10.01.    Securities Subordinated to
                  Senior Debt.
                  ------------

          Anything herein to the contrary notwithstanding, the Company, for
itself and its successors, and each Holder, by his or her acceptance of
Securities, agrees that the payment of all Obligations owing to the Holders in
respect of the Securities is subordinated, to the extent and in the manner
provided in this Article Ten, to the prior payment in full in cash or Cash
Equivalents, or such payment duly provided for to the satisfaction of the
holders of Senior Debt, of all Obligations on Senior Debt.
<PAGE>
 
                                      -97-

          This Article Ten shall constitute a continuing offer to all Persons
who become holders of, or continue to hold, Senior Debt, and such provisions are
made for the benefit of the holders of Senior Debt and such holders are made
obligees hereunder and any one or more of them may enforce such provisions.

SECTION 10.02.  Suspension of Payment When Senior
                Debt Is in Default.
                -------------------

          (a)  Unless Section 10.03 shall be applicable, if any default occurs
and is continuing in the payment when due, whether at maturity, upon any
redemption, by declaration or otherwise, of any principal of, interest on,
unpaid drawings for letters of credit issued in respect of, or regularly
accruing fees with respect to, any Senior Debt (a "Payment Default"), then no
                                                   ---------------           
payment of any kind or character shall be made by or on behalf of the Company or
any other Person on its or their behalf with respect to any Obligations on the
Securities or to acquire any of the Securities for cash or property or otherwise
and until such Payment Default shall have been cured or waived or shall have
ceased to exist or such Senior Debt as to which such Payment Default relates
shall have been discharged or paid in full in cash or Cash Equivalents, after
which the Company shall resume making any and all required payments in respect
of the Securities, including any missed payments.

          (b)  Unless Section 10.03 shall be applicable, if any other event of
default (other than a Payment Default) occurs and is continuing with respect to
any Designated Senior Debt (as such event of default is defined in the
instrument creating or evidencing such Designated Senior Debt) permitting the
holders of such Designated Senior Debt then outstanding to accelerate the
maturity thereof (a "Non-payment Default") and if the Representative for the
                     -------------------                                    
respective issue of Designated Senior Debt gives notice of the event of default
to the Trustee (a "Default Notice"), then, unless and until all events of
                   --------------                                        
default have been cured or waived or have ceased to exist or the Trustee
receives notice thereof from the Representative for the respective issue of
Designated Senior Debt terminating the Payment Blockage Period (as defined
below), during the 180 days 
<PAGE>
 
                                      -98-

after the delivery of such Default Notice (the "Payment Blockage Period"),
                                                -----------------------
neither the Company nor any other Person on its behalf shall (x) make any
payment of any kind or character with respect to any Obligations on the
Securities or (y) acquire any of the Securities for cash or property or
otherwise. Notwithstanding anything herein to the contrary, (x) in no event will
a Payment Blockage Period extend beyond 180 days from the date the payment on
the Securities was due and (y) only one such Payment Blockage Period may be
commenced within any 360 consecutive days. For all purposes of this Section
10.02(b), no event of default which existed or was continuing on the date of the
commencement of any Payment Blockage Period with respect to the Designated
Senior Debt shall be, or be made, the basis for the commencement of a second
Payment Blockage Period by the Representative of such Designated Senior Debt
whether or not within a period of 360 consecutive days, unless such event of
default shall have been cured or waived for a period of not less than 90
consecutive days (it being acknowledged that any subsequent action, or any
breach of any financial covenants for a period commencing after the date of
commencement of such Payment Blockage Period that, in either case, would give
rise to an event of default pursuant to any provisions under which an event of
default previously existed or was continuing shall constitute a new event of
default for this purpose).

          (c)  In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee or any Holder when such payment is prohibited
by the foregoing provisions of this Section 10.02, such payment shall be held in
trust for the benefit of, and shall be paid over or delivered to, the holders of
Senior Debt (pro rata to such holders on the basis of the respective amount of
Senior Debt held by such holders) or their respective Representatives, as their
respective interests may appear.  The Trustee shall be entitled to rely on
information regarding amounts then due and owing on the Senior Debt, if any,
received from the holders of Senior Debt (or their Representatives) or, if such
information is not received from such holders or their Representatives, from the
Company and only amounts included in the information provided to the Trustee
shall be paid to the holders of Senior Debt.
<PAGE>
 
                                      -99-

          Nothing contained in this Article Ten shall limit the right of the
Trustee or the Holders of Securities to take any action to accelerate the
maturity of the Securities pursuant to Section 6.02 or to pursue any rights or
remedies hereunder; provided that all Senior Debt thereafter due or declared to
                    --------                                                   
be due shall first be paid in full in cash or Cash Equivalents before the
Holders are entitled to receive any payment of any kind or character with
respect to Obligations on the Securities.

SECTION 10.03.  Securities Subordinated to Prior Payment
                of All Senior Debt on Dissolution,
                Liquidation or Reorganization of Company.
                -----------------------------------------

          (a)  Upon any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities, to creditors upon
any liquidation, dissolution, winding-up, reorganization, assignment for the
benefit of creditors or marshaling of assets of the Company or in a bankruptcy,
reorganization, insolvency, receivership or other similar proceeding relating to
the Company or its property, whether voluntary or involuntary, all Obligations
due or to become due upon all Senior Debt shall first be paid in full in cash or
Cash Equivalents, or such payment duly provided for to the satisfaction of the
holders of Senior Debt, before any payment or distribution of any kind or
character is made on account of any Obligations on the Securities, or for the
acquisition of any of the Securities for cash or property or otherwise.  Upon
any such dissolution, winding-up, liquidation, reorganization, receivership or
similar proceeding, any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities, to which the Holders
of the Securities or the Trustee under this Indenture would be entitled, except
for the provisions hereof, shall be paid by the Company or by any receiver,
trustee in bankruptcy, liquidating trustee, agent or other Person making such
payment or distribution, or by the Holders or by the Trustee under this
Indenture if received by them, directly to the holders of Senior Debt (pro rata
to such holders on the basis of the respective amounts of Senior Debt held by
such holders) or their respective Representatives, 
<PAGE>
 
                                     -100-

or to the trustee or trustees under any indenture pursuant to which any of such
Senior Debt may have been issued, as their respective interests may appear, for
application to the payment of Senior Debt remaining unpaid until all such Senior
Debt has been paid in full in cash or Cash Equivalents after giving effect to
any concurrent payment, distribution or provision therefor to or for the holders
of Senior Debt.

          (b)  To the extent any payment of Senior Debt (whether by or on behalf
of the Company, as proceeds of security or enforcement of any right of setoff or
otherwise) is declared to be fraudulent or preferential, set aside or required
to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or
other similar Person under any bankruptcy, insolvency, receivership, fraudulent
conveyance or similar law, then, if such payment is recovered by, or paid over
to, such receiver, trustee in bankruptcy, liquidating trustee, agent or other
similar Person, the Senior Debt or part thereof originally intended to be
satisfied shall be deemed to be reinstated and outstanding as if such payment
had not occurred.

          (c)  In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, shall be received by any Holder when such payment or
distribution is prohibited by this Section 10.03(c), such payment or
distribution shall be held in trust for the benefit of, and shall be paid over
or delivered to, the holders of Senior Debt (pro rata to such holders on the
basis of the respective amount of Senior Debt held by such holders) or their
respective Representatives, or to the trustee or trustees under any indenture
pursuant to which any of such Senior Debt may have been issued, as their
respective interests may appear, for application to the payment of Senior Debt
remaining unpaid until all such Senior Debt has been paid in full in cash or
Cash Equivalents, after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of such Senior Debt.

          (d)  The consolidation of the Company with, or the merger of the
Company with or into, another corporation or the liquidation or dissolution of
the Company following the conveyance 
<PAGE>
 
                                     -101-

or transfer of all or substantially all of its assets, to another corporation
upon the terms and conditions provided in Article Five hereof and as long as
permitted under the terms of the Senior Debt shall not be deemed a dissolution,
winding-up, liquidation or reorganization for the purposes of this Section if
such other corporation shall, as a part of such consolidation, merger,
conveyance or transfer, assume the Company's obligations hereunder in accordance
with Article Five hereof.

SECTION 10.04. Payments May Be Paid Prior
               to Dissolution.
               ---------------

          Nothing contained in this Article Ten or elsewhere in this Indenture
shall prevent (i) the Company, except under the conditions described in Sections
10.02 and 10.03, from making payments at any time for the purpose of making
payments of principal of and interest on the Securities, or from depositing with
the Trustee any moneys for such payments, or (ii) in the absence of actual
knowledge by the Trustee that a given payment would be prohibited by Section
10.02 or 10.03, the application by the Trustee of any moneys deposited with it
for the purpose of making such payments of principal of, and interest on, the
Securities to the Holders entitled thereto unless at least two Business Days
prior to the date upon which such payment would otherwise become due and payable
a Trust Officer shall have actually received the written notice provided for in
the first sentence of Section 10.02(b) or in Section 10.07 (provided that,
                                                            ---------     
notwithstanding the foregoing, such application shall otherwise be subject to
the provisions of Section 10.02(a) and Section 10.03).  The Company shall give
prompt written notice to the Trustee of any dissolution, winding-up, liquidation
or reorganization of the Company.

SECTION 10.05.  Holders To Be Subrogated to Rights
                of Holders of Senior Debt.
                --------------------------

          Subject to the payment in full in cash or Cash Equivalents of all
Senior Debt, the Holders of the Securities shall be subrogated to the rights of
the holders of Senior Debt to receive payments or distributions of cash,
property or securities of the Company applicable to the Senior Debt until the
<PAGE>
 
                                     -102-

Securities shall be paid in full; and, for the purposes of such subrogation, no
such payments or distributions to the holders of the Senior Debt by or on behalf
of the Company, or by or on behalf of the Holders by virtue of this Article Ten,
which otherwise would have been made to the Holders shall, as between the
Company and the Holders, be deemed to be a payment by the Company to or on
account of the Senior Debt, it being understood that the provisions of this
Article Ten are and are intended solely for the purpose of defining the relative
rights of the Holders, on the one hand, and the holders of Senior Debt, on the
other hand.

SECTION 10.06. Obligations of the Company Unconditional.
               ---------------------------------------- 

          Nothing contained in this Article Ten or elsewhere in this Indenture
or in the Securities is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Debt, and the Holders, the obligation
of the Company, which is absolute and unconditional, to pay to the Holders the
principal of and any interest on the Securities as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders and creditors of the Company
other than the holders of the Senior Debt, nor shall anything herein or therein
prevent the Holder of any Security or the Trustee on its behalf from exercising
all remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, in respect of cash, property or
securities of the Company received upon the exercise of any such remedy.

SECTION 10.07. Notice to Trustee.
               ----------------- 

          The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Securities pursuant to the provisions of this
Article Ten.  Regardless of anything to the contrary contained in this Article
Ten or elsewhere in this Indenture, the Trustee shall not be charged with
knowledge of the existence of any default or event of default with respect to
any Senior Debt or of any other facts which would prohibit the making of any
payment to

                                     -103-

or by the Trustee unless and until the Trustee shall have received notice in
writing from the Company, or from a holder of Senior Debt or a Representative
therefor, together with proof satisfactory to the Trustee of such holding of
Senior Debt or of the authority of such Representative, and, prior to the
receipt of any such written notice, the Trustee shall be entitled to assume (in
the absence of actual knowledge to the contrary) that no such facts exist.

          In the event that the Trustee determines in good faith that any
evidence is required with respect to the right of any Person as a holder of
Senior Debt to participate in any payment or distribution pursuant to this
Article Ten, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amounts of Senior Debt held by
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article Ten, and if such evidence is not furnished the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.

SECTION 10.08. Reliance on Judicial Order or
               Certificate of Liquidating Agent.
               -------------------------------- 

          Upon any payment or distribution of assets of the Company referred to
in this Article Ten, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders of the Securities shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which any
insolvency, bankruptcy, receivership, dissolution, winding-up, liquidation,
reorganization or similar case or proceeding is pending, or upon a certificate
of the receiver, trustee in bankruptcy, liquidating trustee, assignee for the
benefit of creditors, agent or other person making such payment or distribution,
delivered to the Trustee or the Holders of the Securities, for the purpose of
ascertaining the persons entitled to participate in such payment or
distribution, the holders of the Senior Debt and other Indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
<PAGE>
 
                                     -104-

distributed thereon and all other facts pertinent thereto or to this Article
Ten.

SECTION 10.09. Trustee's Relation to Senior Debt.
               --------------------------------- 

          The Trustee and any agent of the Company or the Trustee shall be
entitled to all the rights set forth in this Article Ten with respect to any
Senior Debt which may at any time be held by it in its individual or any other
capacity to the same extent as any other holder of Senior Debt and nothing in
this Indenture shall deprive the Trustee or any such agent of any of its rights
as such holder.

          With respect to the holders of Senior Debt, the Trustee undertakes to
perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article Ten, and no implied covenants or
obligations with respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee.  The Trustee shall not be deemed to owe any
fiduciary duty to the holders of Senior Debt.

          Whenever a distribution is to be made or a notice given to holders or
owners of Senior Debt, the distribution may be made and the notice may be given
to their Representative, if any.


SECTION 10.10. Subordination Rights Not Impaired
               by Acts or Omissions of the Company
               or Holders of Senior Debt.
               --------------------------

          No right of any present or future holders of any Senior Debt to
enforce subordination as provided herein shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms of this Indenture, regardless of any
knowledge thereof which any such holder may have or otherwise be charged with.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Debt may, at any 
<PAGE>
 
                                     -105-

time and from time to time, without the consent of or notice to the Trustee,
without incurring responsibility to the Trustee or the Holders of the Securities
and without impairing or releasing the subordination provided in this Article
Ten or the obligations hereunder of the Holders of the Securities to the holders
of the Senior Debt, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Debt, or otherwise amend or supplement in any manner Senior Debt, or any
instrument evidencing the same or any agreement under which Senior Debt is
outstanding; (ii) sell, exchange, release or otherwise deal with any property
pledged, mortgaged or otherwise securing Senior Debt; (iii) release any Person
liable in any manner for the payment or collection of Senior Debt; and (iv)
exercise or refrain from exercising any rights against the Company and any other
Person.

SECTION 10.11. Securityholders Authorize Trustee To
               Effectuate Subordination of Securities.
               -------------------------------------- 

          Each Holder of Securities by its acceptance of them authorizes and
expressly directs the Trustee on its behalf to take such action as may be
necessary or appropriate to effectuate, as between the holders of Senior Debt
and the Holders of Securities, the subordination provided in this Article Ten,
and appoints the Trustee its attorney-in-fact for such purposes, including, in
the event of any dissolution, winding-up, liquidation or reorganization of the
Company (whether in bankruptcy, insolvency, receivership, reorganization or
similar proceedings or upon an assignment for the benefit of credits or
otherwise) tending towards liquidation of the business and assets of the
Company, the filing of a claim for the unpaid balance of its Securities and
accrued interest in the form required in those proceedings.

          If the Trustee does not file a proper claim or proof of debt in the
form required in such proceeding prior to 30 days before the expiration of the
time to file such claim or claims, then the holders of the Senior Debt or their
Representative are or is hereby authorized to have the right to file and are or
is hereby authorized to file an appropriate claim 
<PAGE>
 
                                     -106-

for and on behalf of the Holders of said Securities. Nothing herein contained
shall be deemed to authorize the Trustee or the holders of Senior Debt or their
Representative to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof, or to authorize
the Trustee or the holders of Senior Debt or their Representative to vote in
respect of the claim of any Holder in any such proceeding.

SECTION 10.12. This Article Ten Not To
               Prevent Events of Default.
               ------------------------- 

          The failure to make a payment on account of principal of or interest
on the Securities by reason of any provision of this Article Ten will not be
construed as preventing the occurrence of an Event of Default.

SECTION 10.13. Trustee's Compensation
               Not Prejudiced.
               ---------------

                  Nothing in this Article Ten will apply to amounts due to the
Trustee pursuant to other sections of this Indenture.

                                 ARTICLE ELEVEN

                            GUARANTEE OF SECURITIES

SECTION 11.01. Unconditional Guarantee.
               ----------------------- 

          Subject to the provisions of this Article Eleven, each of the
Guarantors hereby, jointly and severally, unconditionally and irrevocably
guarantees, on a senior subordinated basis (such guarantees to be referred to
herein as a "Guarantee") to each Holder of a Security authenticated and
             ---------                                                 
delivered by the Trustee and to the Trustee and its successors and assigns,
irrespective of the validity and enforceability of this Indenture, the
Securities or the obligations of the Company or any other Guarantors to the
Holders or the Trustee hereunder or thereunder, that:  (a) the principal of,
premium, 
<PAGE>
 
                                     -107-

if any, and interest on the Securities shall be duly and punctually paid in full
when due, whether at maturity, upon redemption at the option of Holders pursuant
to the provisions of the Securities relating thereto, by acceleration or
otherwise, and interest on the overdue principal and (to the extent permitted by
law) interest, if any, on the Securities and all other obligations of the
Company or the Guarantors to the Holders or the Trustee hereunder or thereunder
(including amounts due the Trustee under Section 7.07 hereof) and all other
obligations shall be promptly paid in full or performed, all in accordance with
the terms hereof and thereof; and (b) in case of any extension of time of
payment or renewal of any Securities or any of such other obligations, the same
shall be promptly paid in full when due or performed in accordance with the
terms of the extension or renewal, whether at maturity, by acceleration or
otherwise. Failing payment when due of any amount so guaranteed, or failing
performance of any other obligation of the Company to the Holders under this
Indenture or under the Securities, for whatever reason, each Guarantor shall be
obligated to pay, or to perform or cause the performance of, the same
immediately. An Event of Default under this Indenture or the Securities shall
constitute an event of default under this Guarantee, and shall entitle the
Holders of Securities to accelerate the obligations of the Guarantors hereunder
in the same manner and to the same extent as the obligations of the Company.

          Each of the Guarantors hereby agrees that its obligations hereunder
shall be unconditional, irrespective of the validity, regularity or
enforceability of the Securities or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Securities with
respect to any provisions hereof or thereof, any release of any other Guarantor,
the recovery of any judgment against the Company, any action to enforce the
same, whether or not a Guarantee is affixed to any particular Security, or any
other circumstance which might otherwise constitute a legal or equitable
discharge or defense of a Guarantor.  Each of the Guarantors hereby waives the
benefit of diligence, presentment, demand of payment, filing of claims with a
court in the event of insolvency 
<PAGE>
 
                                     -108-

or bankruptcy of the Company, any right to require a proceeding first against
the Company, protest, notice and all demands whatsoever and covenants that its
Guarantee shall not be discharged except by complete performance of the
obligations contained in the Securities, this Indenture and this Guarantee. This
Guarantee is a guarantee of payment and not of collection. If any Holder or the
Trustee is required by any court or otherwise to return to the Company or to any
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Company or such Guarantor, any amount paid by the
Company or such Guarantor to the Trustee or such Holder, this Guarantee, to the
extent theretofore discharged, shall be reinstated in full force and effect.
Each Guarantor further agrees that, as between it, on the one hand, and the
Holders of Securities and the Trustee, on the other hand, (a) subject to this
Article Eleven, the maturity of the obligations guaranteed hereby may be
accelerated as provided in Article Six hereof for the purposes of this
Guarantee, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the obligations guaranteed hereby, and (b) in
the event of any acceleration of such obligations as provided in Article Six
hereof, such obligations (whether or not due and payable) shall forthwith become
due and payable by the Guarantors for the purpose of this Guarantee.

          No stockholder, officer, director, employee or incorporator, past,
present or future, or any Guarantor, as such, shall have any personal liability
under this Guarantee by reason of his, her or its status as such stockholder,
officer, director, employee or incorporator.

          Each Guarantor that makes a payment or distribution under its
Guarantee shall be entitled to a contribution from each other Guarantor,
determined in accordance with GAAP.

SECTION 11.02. Limitations on Guarantees.
               ------------------------- 

          The obligations of each Guarantor under its Guarantee are limited to
the maximum amount which, after giving effect to all other contingent and fixed
liabilities of such Guarantor and after giving effect to any collections from or
payments 
<PAGE>
 
                                     -109-

made by or on behalf of any other Guarantor in respect of the obligations of
such other Guarantor under its Guarantee or pursuant to its contribution
obligations under this Indenture, will result in the obligations of such
Guarantor under the Guarantee not constituting a fraudulent conveyance or
fraudulent transfer under federal or state law. Each Guarantor that makes a
payment or distribution under a Guarantee shall be entitled to a contribution
from each other Guarantor in an amount pro rata, based on the net assets of each
                                       --- ----                                 
Guarantor, determined in accordance with GAAP.

SECTION 11.03. Execution and Delivery of Guarantee.
               ----------------------------------- 

          To further evidence the Guarantee set forth in Section 11.01, each
Guarantor hereby agrees that a notation of such Guarantee, substantially in the
form of Exhibit B hereto, shall be endorsed on each Security authenticated and
        ---------                                                             
delivered by the Trustee.  Such Guarantee shall be executed on behalf of each
Guarantor by either manual or facsimile signature of two Officers of each
Guarantor, each of whom, in each case, shall have been duly authorized to so
execute by all requisite corporate action.  The validity and enforceability of
any Guarantee shall not be affected by the fact that it is not affixed to any
particular Security.

          Each of the Guarantors hereby agrees that its Guarantee set forth in
Section 11.01 shall remain in full force and effect notwithstanding any failure
to endorse on each Security a notation of such Guarantee.

          If an Officer of a Guarantor whose signature is on this Indenture or a
Guarantee no longer holds that office at the time the Trustee authenticates the
Security on which such Guarantee is endorsed or at any time thereafter, such
Guarantor's Guarantee of such Security shall nevertheless be valid.

          The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of any Guarantee set forth in
this Indenture on behalf of each Guarantor.
<PAGE>
 
                                     -110-

SECTION 11.04. Release of a Guarantor.
               ---------------------- 

          (a)  If no Default exists or would exist under this Indenture, upon
the sale or disposition of all of the Capital Stock of a Guarantor by the
Company, in a transaction or series of related transactions that either (i) does
not constitute an Asset Sale or (ii) constitutes an Asset Sale the Net Cash
Proceeds of which are applied in accordance with Section 4.16, or upon the
consolidation or merger of a Guarantor with or into any Person in compliance
with Article Five (in each case, other than to the Company or an Affiliate of
the Company), or if any Guarantor is dissolved or liquidated in accordance with
this Indenture, such Guarantor's Guarantee will be automatically discharged and
released from all obligations under this Article Eleven without any further
action required on the part of the Trustee or any Holder.  Any Guarantor not so
released or the entity surviving such Guarantor, as applicable, shall remain or
be liable under its Guarantee as provided in this Article Eleven.

          (b)  The Trustee shall deliver an appropriate instrument evidencing
the release of a Guarantor upon receipt of a request by the Company or such
Guarantor accompanied by an Officers' Certificate and an Opinion of Counsel
certifying as to the compliance with this Section 11.04; provided, however, that
                                                         --------  -------      
the legal counsel delivering such Opinion of Counsel may rely as to matters of
fact on one or more Officers Certificates of the Company.

          The Trustee shall execute any documents reasonably requested by the
Company or a Guarantor in order to evidence the release of such Guarantor from
its obligations under its Guarantee endorsed on the Securities and under this
Article Eleven.

          Except as set forth in Articles Four and Five and this Section 11.04,
nothing contained in this Indenture or in any of the Securities shall prevent
any consolidation or merger of a Guarantor with or into the Company or another
Guarantor or shall prevent any sale or conveyance of the property of a 
<PAGE>
 
                                     -111-

Guarantor as an entirety or substantially as an entirety to the Company or
another Guarantor.

SECTION 11.05. Waiver of Subrogation.
               --------------------- 

          Until this Indenture is discharged and all of the Securities are
discharged and paid in full, each Guarantor hereby irrevocably waives and agrees
not to exercise any claim or other rights which it may now or hereafter acquire
against the Company that arise from the existence, payment, performance or
enforcement of the Company's obligations under the Securities or this Indenture
and such Guarantor's obligations under this Guarantee and this Indenture, in any
such instance including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution, indemnification, and any right to
participate in any claim or remedy of the Holders against the Company, whether
or not such claim, remedy or right arises in equity, or under contract, statute
or common law, including, without limitation, the right to take or receive from
the Company, directly or indirectly, in cash or other property or by set-off or
in any other manner, payment or security on account of such claim or other
rights.  If any amount shall be paid to any Guarantor in violation of the
preceding sentence and any amounts owing to the Trustee or the Holders of
Securities under the Securities, this Indenture, or any other document or
instrument delivered under or in connection with such agreements or instruments,
shall not have been paid in full, such amount shall have been deemed to have
been paid to such Guarantor for the benefit of, and held in trust for the
benefit of, the Trustee or the Holders and shall forthwith be paid to the
Trustee for the benefit of itself or such Holders to be credited and applied to
the obligations in favor of the Trustee or the Holders, as the case may be,
whether matured or unmatured, in accordance with the terms of this Indenture.
Each Guarantor acknowledges that it will receive direct and indirect benefits
from the financing arrangements contemplated by this Indenture and that the
waiver set forth in this Section 11.05 is knowingly made in contemplation of
such benefits.
<PAGE>
 
                                     -112-

SECTION 11.06. Immediate Payment.
               ----------------- 

          Each Guarantor agrees to make immediate payment to the Trustee on
behalf of the Holders of all Obligations owing or payable to the respective
Holders upon receipt of a demand for payment therefor by the Trustee to such
Guarantor in writing.

SECTION 11.07. No Set-Off.
               ---------- 

          Each payment to be made by a Guarantor hereunder in respect of the
Obligations shall be payable in the currency or currencies in which such
Obligations are denominated, and shall be made without set-off, counterclaim,
reduction or diminution of any kind or nature.

SECTION 11.08. Obligations Absolute.
               -------------------- 

          The obligations of each Guarantor hereunder are and shall be absolute
and unconditional and any monies or amounts expressed to be owing or payable by
each Guarantor hereunder which may not be recoverable from such Guarantor on the
basis of a Guarantee shall be recoverable from such Guarantor as a primary
obligor and principal debtor in respect thereof.

SECTION 11.09. Obligations Continuing.
               ---------------------- 

          The obligations of each Guarantor hereunder shall be continuing and
shall remain in full force and effect until all the obligations have been paid
and satisfied in full.  Each Guarantor agrees with the Trustee that it will from
time to time deliver to the Trustee suitable acknowledgments of this continued
liability hereunder and under any other instrument or instruments in such form
as counsel to the Trustee may advise and as will prevent any action brought
against it in respect of any default hereunder being barred by any statute of
limitations now or hereafter in force and, in the event of the failure of a
Guarantor so to do, it hereby irrevocably appoints the Trustee the attorney and
agent of such Guarantor to make, execute and deliver such written acknowledgment
or acknowledgments or other instruments as may from time to time become
necessary 
<PAGE>
 
                                     -113-

or advisable, in the judgment of the Trustee on the advice of counsel, to fully
maintain and keep in force the liability of such Guarantor hereunder.

SECTION 11.10. Obligations Not Reduced.
               ----------------------- 

          The obligations of each Guarantor hereunder shall not be satisfied,
reduced or discharged solely by the payment of such principal, premium, if any,
interest, fees and other monies or amounts as may at any time prior to discharge
of this Indenture pursuant to Article Eight be or become owing or payable under
or by virtue of or otherwise in connection with the Securities or this
Indenture.

SECTION 11.11. Obligations Reinstated.
               ---------------------- 

          The obligations of each Guarantor hereunder shall continue to be
effective or shall be reinstated, as the case may be, if at any time any payment
which would otherwise have reduced the obligations of any Guarantor hereunder
(whether such payment shall have been made by or on behalf of the Company or by
or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders
upon the insolvency, bankruptcy, liquidation or reorganization of the Company or
any Guarantor or otherwise, all as though such payment had not been made.  If
demand for, or acceleration of the time for, payment by the Company is stayed
upon the insolvency, bankruptcy, liquidation or reorganization of the Company,
all such Indebtedness otherwise subject to demand for payment or acceleration
shall nonetheless be payable by each Guarantor as provided herein.

SECTION 11.12. Obligations Not Affected.
               ------------------------ 

          The obligations of each Guarantor hereunder shall not be affected,
impaired or diminished in any way by any act, omission, matter or thing
whatsoever, occurring before, upon or after any demand for payment hereunder
(and whether or not known or consented to by any Guarantor or any of the
Holders) which, but for this provision, might constitute a whole or partial
defense to a claim against any Guarantor hereunder or 
<PAGE>
 
                                     -114-

might operate to release or otherwise exonerate any Guarantor from any of its
obligations hereunder or otherwise affect such obligations, whether occasioned
by default of any of the Holders or otherwise, including, without limitation:

             (a)  any limitation of status or power, disability, incapacity or
     other circumstance relating to the Company or any other Person, including
     any insolvency, bankruptcy, liquidation, reorganization, readjustment,
     composition, dissolution, winding-up or other proceeding involving or
     affecting the Company or any other Person;

             (b)  any irregularity, defect, unenforceability or invalidity in
     respect of any indebtedness or other obligation of the Company or any other
     Person under this Indenture, the Securities or any other document or
     instrument;

             (c)  any failure of the Company, whether or not without fault on
     its part, to perform or comply with any of the provisions of this Indenture
     or the Securities, or to give notice thereof to a Guarantor;

             (d)  the taking or enforcing or exercising or the refusal or
     neglect to take or enforce or exercise any right or remedy from or against
     the Company or any other Person or their respective assets or the release
     or discharge of any such right or remedy;

             (e)  the granting of time, renewals, extensions, compromises,
     concessions, waivers, releases, discharges and other indulgences to the
     Company or any other Person;

             (f)  any change in the time, manner or place of payment of, or in
     any other term of, any of the Securities, or any other amendment,
     variation, supplement, replacement or waiver of, or any consent to
     departure from, any of the Securities or this Indenture, including, without
     limitation, any increase or decrease in the principal amount of or premium,
     if any, or interest on any of the Securities;
<PAGE>
 
                                     -115-

             (g)  any change in the ownership, control, name, objects,
     businesses, assets, capital structure or constitution of the Company or a
     Guarantor;

             (h)  any merger or amalgamation of the Company or a Guarantor with
     any Person or Persons;

             (i)  the occurrence of any change in the laws, rules, regulations
     or ordinances of any jurisdiction by any present or future action of any
     governmental authority or court amending, varying, reducing or otherwise
     affecting, or purporting to amend, vary, reduce or otherwise affect, any of
     the Obligations or the obligations of a Guarantor under its Guarantee; and

             (j)  any other circumstance, including release of the Guarantor
     pursuant to Section 11.04 (other than by complete, irrevocable payment)
     that might otherwise constitute a legal or equitable discharge or defense
     of the Company under this Indenture or the Securities or of a Guarantor in
     respect of its Guarantee hereunder.

SECTION 11.13. Waiver.
               ------ 

          Without in any way limiting the provisions of Section 11.01 hereof,
each Guarantor hereby waives notice of acceptance hereof, notice of any
liability of any Guarantor hereunder, notice or proof of reliance by the Holders
upon the obligations of any Guarantor hereunder, and diligence, presentment,
demand for payment on the Company, protest, notice of dishonor or non-payment of
any of the Obligations, or other notice or formalities to the Company or any
Guarantor of any kind whatsoever.

SECTION 11.14. No Obligation To Take Action Against
               the Company.
               ------------

          Neither the Trustee nor any other Person shall have any obligation to
enforce or exhaust any rights or remedies or to take any other steps under any
security for the Obligations or against the Company or any other Person or any
property of 
<PAGE>
 
                                     -116-

the Company or any other Person before the Trustee is entitled to demand payment
and performance by any or all Guarantors of their liabilities and obligations
under their Guarantees or under this Indenture.

SECTION 11.15. Dealing with the Company and Others.
               ----------------------------------- 

          The Holders, without releasing, discharging, limiting or otherwise
affecting in whole or in part the obligations and liabilities of any Guarantor
hereunder and without the consent of or notice to any Guarantor, may

             (a)  grant time, renewals, extensions, compromises, concessions,
     waivers, releases, discharges and other indulgences to the Company or any

                          SUBORDINATION OF GUARANTEE

SECTION 12.01. Guarantee Obligations Subordinated
               to Guarantor Senior Debt.
               -------------------------

          Anything herein to the contrary notwithstanding, each of the
Guarantors, for itself and its successors, and each Holder, by his or her
acceptance of Guarantees, agrees that the payment of all Obligations owing to
the Holders in respect of its Guarantee (collectively, as to any Guarantor, its
"Guarantee Obligations") is subordinated, to the extent and in the manner
 ---------------------                                                   
provided in this Article Twelve, to the prior payment in full in cash or Cash
Equivalents, or such payment duly provided for to the satisfaction of the
holders of Guarantor Senior Debt, of all Obligations on Guarantor Senior Debt of
such Guarantor.

          This Article Twelve shall constitute a continuing offer to all Persons
who become holders of, or continue to hold, Guarantor Senior Debt, and such
provisions are made for the benefit of the holders of Guarantor Senior Debt and
such holders are made obligees hereunder and any one or more of them may enforce
such provisions.

SECTION 12.02. Suspension of Guarantee Obligations
               When Guarantor Senior Debt Is in Default.
               -----------------------------------------

          (a)  Unless Section 12.03 shall be applicable, if any Payment Default
occurs and is continuing with respect to any Guarantor Senior Debt, then no
payment of any kind or character shall be made by or on behalf of such Guarantor
or any other Person on its behalf with respect to any Guarantee Obligations or
to acquire any of the Securities for cash or property or 
<PAGE>
 
                                     -120-

otherwise and until such Payment Default shall have been cured or waived or
shall have ceased to exist or such Guarantor Senior Debt shall have been
discharged or paid in full in cash or Cash Equivalents, after which such
Guarantor shall resume making any and all required payments in respect of its
obligations under this Guarantee, including any missed payments.

          (b)  Unless Section 12.03 shall be applicable, if any Non-payment
Default occurs and is continuing with respect to any Designated Senior Debt
under which a Guarantor is a primary obligor or which is guaranteed by a
Guarantor (which obligation or guarantee constitutes Guarantor Senior Debt of
such Guarantor) (as such event of default is defined in the instrument creating
or evidencing such Designated Senior Debt) and if the Representative for the
respective issue of Designated Senior Debt gives a Default Notice to the
Trustee, then, unless and until all events of default have been cured or waived
or have ceased to exist or the Trustee receives notice thereof from the
Representative for the respective issue of Designated Senior Debt terminating
the Guarantor Payment Blockage Period (as defined below), during the 180 days
after the delivery of such Default Notice (the "Guarantor Payment Blockage
                                                --------------------------
Period"), neither such Guarantor nor any other Person on its behalf shall (x)
- ------                                                                       
make any payment of any kind or character with respect to any Obligations on its
Guarantee or (y) acquire any of the Securities for cash or otherwise.
Notwithstanding anything herein to the contrary, (x) in no event will a
Guarantor Payment Blockage Period extend beyond 180 days from the date the
payment on a Guarantee was due and (y) only one such Guarantor Payment Blockage
Period may be commenced within any 360 consecutive days.  For all purposes of
this Section 12.02(b), no event of default which existed or was continuing on
the date of the commencement of any Guarantor Payment Blockage Period with
respect to the Designated Senior Debt of a Guarantor shall be, or be made, the
basis for the commencement of a second Guarantor Payment Blockage Period by the
Representative of such Designated Senior Debt whether or not within a period of
360 consecutive days, unless such event of default shall have been cured or
waived for a period of not less than 90 consecutive days (it being acknowledged
that any subsequent action, or any 
<PAGE>
 
                                     -121-


breach of any financial covenants for a period commencing after the date of
commencement of such Guarantor Payment Blockage Period that, in either case,
would give rise to an event of default pursuant to any provisions under which an
event of default previously existed or was continuing shall constitute a new
event of default for this purpose).

          (c)  In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee or any Holder when such payment is prohibited
by the foregoing provisions of this Section 12.02, such payment shall be held in
trust for the benefit of, and shall be paid over or delivered to, the holders of
Guarantor Senior Debt (pro rata to such holders on the basis of the respective
amount of Guarantor Senior Debt held by such holders) or their respective
Representatives, as their respective interests may appear.  The Trustee shall be
entitled to rely on information regarding amounts then due and owing on the
Guarantor Senior Debt, if any, received from the holders of Guarantor Senior
Debt (or their Representatives) or, if such information is not received from
such holders or their Representatives, from a Guarantor and only amounts
included in the information provided to the Trustee shall be paid to the holders
of Guarantor Senior Debt.

SECTION 12.03. Guarantee Obligations Subordinated
               to Prior Payment of All Guarantor
               Senior Debt on Dissolution, Liquidation
               or Reorganization of Such Guarantor.
               ------------------------------------

          (a)  Upon any payment or distribution of assets of any Guarantor of
any kind or character, whether in cash, property or securities, to creditors
upon any liquidation, dissolution, winding-up, reorganization, assignment for
the benefit of creditors or marshaling of assets of such Guarantor or in a
bankruptcy, reorganization, insolvency, receivership or other similar proceeding
relating to such Guarantor or its property, whether voluntary or involuntary,
all Obligations due or to become due upon all Guarantor Senior Debt shall first
be paid in full in cash or Cash Equivalents, or such payment duly provided for
to the satisfaction of the holders of Guarantor Senior Debt, before any payment
or distribution of any kind or character 
<PAGE>
 
                                     -122-

is made on account of any Guarantee Obligations or for the acquisition of any of
the Securities for cash or property or otherwise. Upon any such dissolution,
winding-up, liquidation, reorganization, receivership or similar proceeding, any
payment or distribution of assets of such Guarantor of any kind or character,
whether in cash, property or securities, to which the Holders or the Trustee
under this Indenture would be entitled, except for the provisions hereof, shall
be paid by such Guarantor or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making such payment or distribution, or by the
Holders or by the Trustee under this Indenture if received by them, directly to
the holders of Guarantor Senior Debt (pro rata to such holders on the basis of
the respective amounts of Guarantor Senior Debt held by such holders) or their
respective Representatives, or to the trustee or trustees under any indenture
pursuant to which any of such Guarantor Senior Debt may have been issued, as
their respective interests may appear, for application to the payment of
Guarantor Senior Debt remaining unpaid until all such Guarantor Senior Debt has
been paid in full in cash or Cash Equivalents after giving effect to any
concurrent payment, distribution or provision therefor to or for the holders of
Guarantor Senior Debt.

          (b)  To the extent any payment of Guarantor Senior Debt (whether by or
on behalf of a Guarantor, as proceeds of security or enforcement of any right of
setoff or otherwise) is declared to be fraudulent or preferential, set aside or
required to be paid to any receiver, trustee in bankruptcy, liquidating trustee,
agent or other similar Person under any bankruptcy, insolvency, receivership,
fraudulent conveyance or similar law, then, if such payment is recovered by, or
paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent
or other similar Person, the Guarantor Senior Debt or part thereof originally
intended to be satisfied shall be deemed to be reinstated and outstanding as if
such payment had not occurred.

          (c)  In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of 
<PAGE>
 
                                     -123-

any kind or character, whether in cash, property or securities, shall be
received by any Holder when such payment or distribution is prohibited by this
Section 12.03(c), such payment or distribution shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Guarantor
Senior Debt (pro rata to such holders on the basis of the respective amount of
Guarantor Senior Debt held by such holders) or their respective Representatives,
or to the trustee or trustees under any indenture pursuant to which any of such
Guarantor Senior Debt may have been issued, as their respective interests may
appear, for application to the payment of Guarantor Senior Debt remaining unpaid
until all such Guarantor Senior Debt has been paid in full in cash or Cash
Equivalents, after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of such Guarantor Senior Debt.

          (d)  The consolidation of any Guarantor with, or the merger of any
Guarantor with or into, another corporation or the liquidation or dissolution of
a Guarantor following the conveyance or transfer of all or substantially all of
its assets, to another corporation upon the terms and conditions provided in
Article Five hereof and as long as permitted under the terms of the Guarantor
Senior Debt shall not be deemed a dissolution, winding-up, liquidation or
reorganization for the purposes of this Section if such other corporation shall,
as a part of such consolidation, merger, conveyance or transfer, assumes the
Guarantee of such Guarantor hereunder in accordance with Article Five hereof.

SECTION 12.04. Payments May Be Paid Prior
               to Dissolution.
               ---------------

          Nothing contained in this Article Twelve or elsewhere in this
Indenture shall prevent (i) any Guarantor, except under the conditions described
in Sections 12.02 and 12.03, from making payments at any time for the purpose of
making payments on Guarantee Obligations, or from depositing with the Trustee
any moneys for such payments, or (ii) in the absence of actual knowledge by the
Trustee that a given payment would be prohibited by Section 12.02 or 12.03, the
application by the Trustee 
<PAGE>
 
                                     -124-

of any moneys deposited with it for the purpose of making such payments on
Guarantee Obligations to the Holders entitled thereto unless at least two
Business Days prior to the date upon which such payment would otherwise become
due and payable a Trust Officer shall have actually received the written notice
provided for in the first sentence of Section 12.02(b) or in Section 12.07
(provided that, notwithstanding the foregoing, such application shall otherwise

be subject to the provisions of Section 12.02(a) and Section 12.03). Each
Guarantor shall give prompt written notice to the Trustee of any dissolution,
winding-up, liquidation or reorganization of such Guarantor.

SECTION 12.05. Holders of Guarantee Obligations
               To Be Subrogated to Rights of
               Holders of Guarantor Senior Debt.
               ---------------------------------

          Subject to the payment in full in cash or Cash Equivalents of all
Guarantor Senior Debt, the Holders of Guarantee Obligations of any Guarantor
shall be subrogated to the rights of the holders of Guarantor Senior Debt of
such Guarantor to receive payments or distributions of cash, property or
securities of such Guarantor applicable to such Guarantor Senior Debt until all
amounts owing on or in respect of the Guarantee Obligations shall be paid in
full; and, for the purposes of such subrogation, no such payments or
distributions to the holders of such Guarantor Senior Debt by or on behalf of
such Guarantor, or by or on behalf of the Holders by virtue of this Article
Twelve, which otherwise would have been made to the Holders shall, as between
such Guarantor and the Holders, be deemed to be a payment by such Guarantor to
or on account of such Guarantor Senior Debt, it being understood that the
provisions of this Article Twelve are and are intended solely for the purpose of
defining the relative rights of the Holders, on the one hand, and the holders of
Guarantor Senior Debt, on the other hand.

SECTION 12.06.   Obligations of the Guarantors Unconditional.
                 ------------------------------------------- 

          Nothing contained in this Article Twelve or elsewhere in this

Guarantors, their creditors other than the 
<PAGE>
 
                                     -125-

holders of Guarantor Senior Debt, and the Holders, the obligation of the
Guarantors, which is absolute and unconditional, to pay to the Holders all
amounts due and payable under the Guarantees as and when the same shall become
due and payable in accordance with their terms, or is intended to or shall
affect the relative rights of the Holders and creditors of the Guarantors other
than the holders of the Guarantor Senior Debt, nor shall anything herein or
therein prevent any Holder or the Trustee on its behalf from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, in respect of cash, property or
securities of the Guarantors received upon the exercise of any such remedy.

SECTION 12.07. Notice to Trustee.
               ----------------- 

          Each Guarantor shall give prompt written notice to the Trustee of any
fact known to such Guarantor which would prohibit the making of any payment to
or by the Trustee in respect of the Guarantees pursuant to the provisions of
this Article Twelve.  Regardless of anything to the contrary contained in this
Article Twelve or elsewhere in this Indenture, the Trustee shall not be charged
with knowledge of the existence of any default or event of default with respect
to any Guarantor Senior Debt or of any other facts which would prohibit the
making of any payment to or by the Trustee unless and until the Trustee shall
have received notice in writing from a Guarantor, or from a holder of Guarantor
Senior Debt or a Representative therefor, together with proof satisfactory to
the Trustee of such holding of Guarantor Senior Debt or of the authority of such
Representative, and, prior to the receipt of any such written notice, the
Trustee shall be entitled to assume (in the absence of actual knowledge to the
contrary) that no such facts exist.

          In the event that the Trustee determines in good faith that any
evidence is required with respect to the right of any Person as a holder of
Guarantor Senior Debt to participate in any payment or distribution pursuant to
this Article Twelve, the Trustee may request such Person to furnish evidence to
the reasonable satisfaction of the Trustee as to the amounts 
<PAGE>
 
                                     -126-

of Guarantor Senior Debt held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article Twelve, and if such
evidence is not furnished the Trustee may defer any payment to such Person
pending judicial determination as to the right of such Person to receive such
payment.

SECTION 12.08. Reliance on Judicial Order or
               Certificate of Liquidating Agent.
               -------------------------------- 

          Upon any payment or distribution of assets of a Guarantor referred to
in this Article Twelve, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders shall be entitled to rely upon any order or decree made
by any court of competent jurisdiction in which any insolvency, bankruptcy,
receivership, dissolution, winding-up, liquidation, reorganization or similar
case or proceeding is pending, or upon a certificate of the trustee in
bankruptcy, liquidating trustee, receiver, assignee for the benefit of
creditors, agent or other person making such payment or distribution, delivered
to the Trustee or the Holders, for the purpose of ascertaining the persons
entitled to participate in such payment or distribution, the holders of the
Guarantor Senior Debt and other Indebtedness of such Guarantor, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article Twelve.

SECTION 12.09. Trustee's Relation to Guarantor Senior Debt.
               ------------------------------------------- 

          The Trustee and any agent of a Guarantor or the Trustee shall be
entitled to all the rights set forth in this Article Twelve with respect to any
Guarantor Senior Debt which may at any time be held by it in its individual or
any other capacity to the same extent as any other holder of Guarantor Senior
Debt and nothing in this Indenture shall deprive the Trustee or any such agent
of any of its rights as such holder.

          With respect to the holders of Guarantor Senior Debt, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in 
<PAGE>
 
                                     -127-

this Article Twelve, and no implied covenants or obligations with respect to the
holders of Guarantor Senior Debt shall be read into this Indenture against the
Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Guarantor Senior Debt.

          Whenever a distribution is to be made or a notice given to holders or
owners of Guarantor Senior Debt, the distribution may be made and the notice may
be given to their Representative, if any.

SECTION 12.10. Subordination Rights Not Impaired
               by Acts or Omissions of the Guarantors
               or Holders of Guarantor Senior Debt.
               ------------------------------------

          No right of any present or future holders of any Guarantor Senior Debt
to enforce subordination as provided herein shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of any Guarantor
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by any Guarantor with the terms of this Indenture, regardless of
any knowledge thereof which any such holder may have or otherwise be charged
with.

          Without in any way limiting the generality of the foregoing paragraph,
the holders of Guarantor Senior Debt may, at any time and from time to time,
without the consent of or notice to the Trustee, without incurring
responsibility to the Trustee or the Holders of the Securities and without
impairing or releasing the subordination provided in this Article Twelve or the
obligations hereunder of the Holders of the Securities to the holders of
Guarantor Senior Debt, do any one or more of the following:  (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, Guarantor Senior Debt, or otherwise amend or supplement in any manner
Guarantor Senior Debt, or any instrument evidencing the same or any agreement
under which Guarantor Senior Debt is outstanding; (ii) sell, exchange, release
or otherwise deal with any property pledged, mortgaged or otherwise securing
Guarantor Senior Debt; (iii) release any Person liable in any manner for the
payment or collection of Guarantor Senior Debt; and 
<PAGE>
 
                                     -128-

(iv) exercise or refrain from exercising any rights against the Guarantors and
any other Person.

SECTION 12.11. Holders Authorize Trustee To Effectuate
               Subordination of Guarantee Obligations.
               ---------------------------------------

          Each Holder of Guarantee Obligations by its acceptance of them
authorizes and expressly directs the Trustee on its behalf to take such action
as may be necessary or appropriate to effectuate, as between the holders of
Guarantor Senior Debt and the Holders, the subordination provided in this
Article Twelve, and appoints the Trustee its attorney-in-fact for such purposes,
including, in the event of any dissolution, winding-up, liquidation or
reorganization of any Guarantor (whether in bankruptcy, insolvency,
receivership, reorganization or similar proceedings or upon an assignment for
the benefit of credits or otherwise) tending towards liquidation of the business
and assets of any Guarantor, the filing of a claim for the unpaid balance under
its Guarantee Obligations and accrued interest in the form required in those
proceedings.

          If the Trustee does not file a proper claim or proof of debt in the
form required in such proceeding prior to 30 days before the expiration of the
time to file such claim or claims, then the holders of the Guarantor Senior Debt
or their Representative are or is hereby authorized to have the right to file
and are or is hereby authorized to file an appropriate claim for and on behalf
of the Holders of said Guarantee Obligations.  Nothing herein contained shall be
deemed to authorize the Trustee or the holders of Guarantor Senior Debt or their
Representative to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Guarantee Obligations or the rights of any Holder thereof, or to
authorize the Trustee or the holders of Guarantor Senior Debt or their
Representative to vote in respect of the claim of any Holder in any such
proceeding.

on the Guarantees by reason of any provision of this Article Twelve will not be
construed as preventing the occurrence of an Event of Default.

          The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000.  A Holder shall
register the transfer of or exchange Securities in accordance with the
Indenture.  The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture.  The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any security being redeemed in part.

12. Persons Deemed Owners.
    --------------------- 

                  The registered Holder of a Security shall be treated as the
owner of it for all purposes.

13. Unclaimed Funds.
    --------------- 

          If funds for the payment of principal or interest remain unclaimed for
one year, the Trustee and the Paying Agent will repay the funds to the Company
at its request.  After that, all liability of the Trustee and such Paying Agent
with respect to such funds shall cease.

14. Discharge Prior to Redemption or Maturity.
    ----------------------------------------- 

          The Company and the Guarantors may be discharged from their
obligations under the Indenture, the Securities and the Guarantees except for
certain provisions thereof, and may be discharged from obligations to comply
with certain covenants contained in the Indenture, the Securities and the
Guarantees, 
<PAGE>
 
in each case upon satisfaction of certain conditions specified in the Indenture.

15. Amendment; Supplement; Waiver.
    ----------------------------- 

          Subject to certain exceptions, the Indenture, the Securities and the
Guarantees may be amended or supplemented with the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities
then outstanding, and any existing Default or Event of Default or compliance
with any provision may be waived with the consent of the Holders of a majority
in aggregate principal amount of the Securities then outstanding.  Without
notice to or consent of any Holder, the parties thereto may amend or supplement
the Indenture, the Securities and the Guarantees to, among other things, cure
any ambiguity, defect or inconsistency, provide for uncertificated Securities in
addition to or in place of certificated Securities or comply with any
requirements of the Commission in connection with the qualification of the
Indenture under the TIA, or make any other change that does not materially
adversely affect the rights of any Holder of a Security.

16. Restrictive Covenants.
    --------------------- 

          The Indenture contains certain covenants that, among other things,
limit the ability of the Company and its Restricted Subsidiaries to make
restricted payments, to incur indebtedness, to create liens, to sell assets, to
permit restrictions on dividends and other payments by Restricted Subsidiaries
of the Company to the Company, to consolidate, merge or sell all or
substantially all of its assets or to engage in transactions with affiliates.
The limitations are subject to a number of important qualifications and
exceptions.  The Company must annually report to the Trustee on compliance with
such limitations.
<PAGE>
 
17. Defaults and Remedies.
    --------------------- 

          If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in aggregate principal amount of Securities then
outstanding may declare all the Securities to be due and payable immediately in
the manner and with the effect provided in the Indenture.  Holders of Securities
may not enforce the Indenture, the Securities or the Guarantees except as
provided in the Indenture.  The Trustee is not obligated to enforce the
Indenture, the Securities or the Guarantees unless it has received indemnity
satisfactory to it.  The Indenture permits, subject to certain limitations
therein provided, Holders of a majority in aggregate principal amount of the
Securities then outstanding to direct the Trustee in its exercise of any trust
or power.  The Trustee may withhold from Holders of Securities notice of certain
continuing Defaults or Events of Default if it determines that withholding
notice is in their interest.

18. Trustee Dealings with Company.
    ----------------------------- 

          The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities and may otherwise deal
with the Company, its Subsidiaries or their respective Affiliates as if it were
not the Trustee.

19. No Recourse Against Others.
    -------------------------- 

          No stockholder, director, officer, employee or incorporator, as such,
of the Company shall have any liability for any obligation of the Company under
the Securities or the Indenture or for any claim based on, in respect of or by
reason of, such obligations or their creation.  Each Holder of a Security by
accepting a Security waives and releases all such liability.  The waiver and
release are part of the consideration for the issuance of the Securities.

20. Authentication.
    -------------- 
<PAGE>
 
          This Security shall not be valid until the Trustee or authenticating
agent signs the certificate of authentication on this Security.

21. Abbreviations and Defined Terms.
    ------------------------------- 

          Customary abbreviations may be used in the name of a Holder of a
Security or an assignee, such as:  TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

22. Governing Law.
    ------------- 

          This Security shall be governed by, and construed in accordance with,
the laws of the State of New York without giving effect to applicable principles
of conflicts of laws to the extent that the application of the laws of another
jurisdiction would be required thereby.

23. CUSIP Numbers.
    ------------- 

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities as a convenience to the Holders of the Securities.  No

Securities and reliance may be placed only on the other identification numbers
printed hereon.

                             ALLIANCE IMAGING, INC.
                Senior Subordinated Floating Rate Note due 2005

1.  Interest.
    -------- 

          ALLIANCE IMAGING, INC., a Delaware corporation (the "Company"),
promises to pay interest on the principal amount of this Security at the rate
per annum, reset semi-annually equal to LIBOR (as defined below) plus [     ]%,
as determined by the Calculation Agent.  Interest on the Floating Rate Notes (as
defined below) will accrue from the most recent date on which interest has been
paid or, if no interest has been paid, from           , 1997.  The Company will
pay interest semi-annually on each               and              (each, an
"Interest Payment Date") for the period commencing on and including the
immediately preceding Interest Payment Date and ending on and including the day
next preceding the Interest Payment Date (an "Interest Period"), with the
exception that the first Interest Period shall commence on and include December
, 1997 and end on and include             , 1998, and at stated maturity,
commencing on               , 1998.

          The Company shall pay interest on overdue principal and on overdue
installments of interest from time to time on demand at the rate borne by the
Floating Rate Notes and on overdue installments of interest (without regard to
any applicable grace periods) to the extent lawful.

          "LIBOR", with respect to an Interest Period, shall be the rate
(expressed as a percentage per annum) for deposits in United States dollars for
a six-month period beginning on the second London Banking Day (as defined) after
the Determination Date (as defined) that appears on Telerate Page 3750 (as
defined) as of 11:00 a.m., London time, on the Determination Date.  If Telerate
Page 3750 does not include such a rate or is 
<PAGE>
 
                                      -6-


unavailable on a Determination Date, LIBOR for the Interest Period shall be the
arithmetic mean of the rates (expressed as a percentage per annum) for deposits
in a Representative Amount (as defined) in United States dollars for a six-month
period beginning on the second London Banking Day after the Determination Date
that appears on Reuters Screen LIBO Page (as defined) as of 11:00 a.m., London
time, on the Determination Date. If Reuters Screen LIBO Page does not include
two or more rates or is unavailable on a Determination Date, the Calculation
Agent will request the principal London office of each of four major banks in
the London interbank market, as selected by the Calculation Agent, to provide
such bank's offered quotation (expressed as a percentage per annum), as of
approximately 11:00 a.m., London time, on such Determination Date, to prime
banks in the London interbank market for deposits in a Representative Amount in
United States dollars for a six-month period beginning on the second London
Banking Day after the Determination Date. If at least two such offered
quotations are so provided, LIBOR for the Interest Period will be the arithmetic
mean of such quotations. If fewer than two such quotations are so provided, the
Calculation Agent will request each of three major banks in New York City, as
selected by the Calculation Agent, to provide such bank's rate (expressed as a
percentage per annum), as of approximately 11:00 a.m., New York City time, on
such Determination Date, for loans in a Representative Amount in United States
dollars to leading European banks for a six-month period beginning on the second
London Banking Day after the Determination Date. If at least two such rates are
so provided, LIBOR for the Interest Period will be the arithmetic mean of such
rates. If fewer than two such rates are so provided, then LIBOR for the Interest
Period will be LIBOR in effect with respect to the immediately preceding
Interest Period.

          "Determination Date," with respect to an Interest Period, will be the
second London Banking Day preceding the first day of the Interest Period.

          "London Banking Day" is any day in which dealings in United States
dollars are transacted or, with respect to any 
<PAGE>
 
                                      -7-


future date, are expected to be transacted in the London interbank market.

          "Representative Amount"  means a principal amount of not less than
U.S. $1,000,000 for a single transaction in the relevant market at the relevant
time.

          "Telerate Page 3750" means the display designated as "Page 3750" on
the Dow Jones Telerate Service (or such other page as may replace Page 3750 on
that service).

          "Reuters Screen LIBO Page" means the display designated as page "LIBO"
on The Reuters Monitor Money Rates Service (or such other page as may replace
the LIBO page on that service).

          The amount of interest for each day that the Floating Rate Notes are
outstanding (the "Daily Interest Amount") will be calculated by dividing the
interest rate in effect for such day by 360 and multiplying the result by the
principal amount of the Floating Rate Notes.  The amount of interest to be paid
on the Floating Rate Notes for each Interest Period will be calculated by adding
the Daily Interest Amounts for each day in the Interest Period.

          All percentages resulting from any of the above calculations will be
rounded, if necessary, to the nearest one hundred-thousandth of a percentage
point, with five one-millionths of a percentage point rounded upwards (e.g.,
9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)) and all dollar
amounts used in or resulting from such calculations will be rounded to the
nearest cent (with one-half cent being rounded upwards).

          The interest rate on the Floating Rate Notes will in no event be
higher than the maximum rate permitted by New York law as the same may be
modified by United States law of general application.  Under current New York
law, the maximum rate of interest is 25% per annum on a simple interest basis.
This limit may not apply to Floating Rate Notes in which $2,500,000 or more has
been invested.
<PAGE>
 
                                      -8-

          The Calculation Agent will, upon the request of the holder of any
Floating Rate Note, provided the interest rate then in effect with respect to
the Floating Rate Notes.  All calculations made by the Calculation Agent in the
absence of manifest error shall be conclusive for all purposes and binding on
the Company and the Holders of the Floating Rate Notes.

2. Method of Payment.
   ----------------- 

          The Company shall pay interest on the Securities (except defaulted
interest) to the persons who are the registered Holders at the close of business
on the Record Date immediately preceding the Interest Payment Date even if the
Securities are cancelled on registration of transfer or registration of exchange
after such Record Date.  Holders must surrender Securities to a Paying Agent to
collect principal payments.  The Company shall pay principal and interest in
money of the United States that at the time of payment is legal tender for
payment of public and private debts ("U.S. Legal Tender").  However, the Company
may pay principal and interest by wire transfer of Federal funds, or interest by
check payable in such U.S. Legal Tender.  The Company may deliver any such
interest payment to the Paying Agent or to a Holder at the Holder's registered
address.

3. Paying Agent, Registrar and 
   Calculation Agent.
   ----------------------------

          Initially, IBJ Schroder Bank & Trust Company (the "Trustee") will act
as Paying Agent, Registrar and Calculation Agent.  The Company may change any
Paying Agent, Registrar, co-Registrar or Calculation Agent without notice to the
Holders.  The Company or any of its Subsidiaries may, subject to certain
exceptions, act as Registrar or co-Registrar.

4. Indenture.
   --------- 

          The Company issued the Securities under an Indenture, dated as of
December   , 1997 (the "Indenture"), among the Company, each of the Guarantors
named therein and the Trustee.  
<PAGE>
 
                                      -9-


This Security is one of a duly authorized issue of Securities of the Company
designated as its Senior Floating Rate Notes due 2005 (the "Floating Rate
Notes"). The Securities include the Floating Rate Notes and the Fixed Rate Notes

terms of the Securities include those stated in this Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C.
(S)(S) 77aaa-77bbbb) (the "TIA"), as in effect on the date of this Indenture
until such time as the Indenture is qualified under the TIA. Notwithstanding
anything to the contrary herein, the Securities are subject to all such terms,
and Holders of Securities are referred to the Indenture and the TIA for a
statement of them. The Securities are general obligations of the Company limited
in aggregate principal amount to $265,000,000.

5. Subordination.
   ------------- 

          The Securities are subordinated in right of payment, in the manner and
to the extent set forth in the Indenture, to the prior payment in full in cash
or Cash Equivalents of all Senior Debt of the Company, whether outstanding on
the date of the Indenture or thereafter created, incurred, assumed or
guaranteed.  Each Holder by his acceptance hereof agrees to be bound by such
provisions and authorizes and expressly directs the Trustee, on his behalf, to
take such action as may be necessary or appropriate to effectuate the
subordination provided for in the Indenture and appoints the Trustee his
attorney-in-fact for such purposes.

in whole at any time or in part from time to time, upon not less than 30 nor
more than 60 days' notice, at the following redemption prices (expressed as
percentages of the principal amount thereof) if redeemed during the twelve-

7. Notice of Redemption.
   -------------------- 

          Notice of redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each Holder of Securities to be redeemed
at such Holder's registered address.  Securities in denominations larger than
$1,000 may be redeemed only in whole.  The Trustee may select for redemption
portions (equal to $1,000 or any integral multiple thereof) of the principal of
Securities that have denominations larger than $1,000.

          If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed.  A new Security in a principal amount
equal to the unredeemed portion thereof will be issued in the name of the Holder
thereof upon cancellation of the original Security.  On and after the Redemption
Date, interest will cease to accrue on Securities or portions thereof called for
redemption.

8. Change of Control Offer.
   ----------------------- 

          Upon the occurrence of a Change of Control, the Company will be
required to offer to purchase all of the outstanding Securities at a purchase

10. Denominations; Transfer; Exchange.
    --------------------------------- 

          The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000.  A Holder shall
register the transfer of or exchange Securities in accordance with the
Indenture.  The Registrar may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and to pay certain transfer
taxes or similar governmental charges payable in connection therewith as
permitted by the Indenture.  The Registrar need not register the transfer of or
exchange any Securities or portions thereof selected for redemption, except the
unredeemed portion of any security being redeemed in part.

11. Persons Deemed Owners.
    --------------------- 

           The registered Holder of a Security shall be treated as the
owner of it for all purposes.

12. Unclaimed Funds.
    --------------- 

          If funds for the payment of principal or interest remain unclaimed for
one year, the Trustee and the Paying Agent will repay the funds to the Company
at its request.  After that, all liability of the Trustee and such Paying Agent
with respect to such funds shall cease.

13. Discharge Prior to Redemption or Maturity.
    ----------------------------------------- 

          The Company and the Guarantors may be discharged from their
obligations under the Indenture, the Securities and the Guarantees except for

Guarantees may be amended or supplemented with the written consent of the
Holders of at least a majority in aggregate principal amount of the Securities
then outstanding, and any existing Default or Event of Default or compliance
with any provision may be waived with the consent of the Holders of a majority
in aggregate principal amount of the Securities then outstanding.  Without
notice to or consent of any Holder, the parties thereto may amend or supplement
the Indenture, the Securities and the Guarantees to, among other things, cure
any ambiguity, defect or inconsistency, provide for uncertificated Securities in
addition to or in place of certificated Securities or comply with any
requirements of the Commission in connection with the qualification of the
Indenture under the TIA, or make any other change that does not materially
adversely affect the rights of any Holder of a Security.

15. Restrictive Covenants.
    ---------------------

limit the ability of the Company and its Restricted Subsidiaries to make
restricted payments, to incur indebtedness, to create liens, to sell assets, to

exceptions.  The Company must annually report to the Trustee on compliance with
such limitations.

16. Defaults and Remedies.
    --------------------- 

          If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in aggregate principal 
<PAGE>
 
                                     -13-


amount of Securities then outstanding may declare all the Securities to be due
and payable immediately in the manner and with the effect provided in the
Indenture. Holders of Securities may not enforce the Indenture, the Securities
or the Guarantees except as provided in the Indenture. The Trustee is not
obligated to enforce the Indenture, the Securities or the Guarantees unless it
has received indemnity satisfactory to it. The Indenture permits, subject to
certain limitations therein provided, Holders of a majority in aggregate
principal amount of the Securities then outstanding to direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of
Securities notice of certain continuing Defaults or Events of Default if it
determines that withholding notice is in their interest.

17. Trustee Dealings with Company.
    ----------------------------- 

          The Trustee under the Indenture, in its individual or any other
capacity, may become the owner or pledgee of Securities and may otherwise deal
with the Company, its Subsidiaries or their respective Affiliates as if it were
not the Trustee.

18. No Recourse Against Others.
    -------------------------- 

          No stockholder, director, officer, employee or incorporator, as such,
of the Company shall have any liability for any obligation of the Company under
the Securities or the Indenture or for any claim based on, in respect of or by
reason of, such obligations or their creation.  Each Holder of a Security by
accepting a Security waives and releases all such liability.  The waiver and
release are part of the consideration for the issuance of the Securities.

19. Authentication.
    -------------- 

          This Security shall not be valid until the Trustee or authenticating
agent signs the certificate of authentication on this Security.

20. Abbreviations and Defined Terms.
    ------------------------------- 
<PAGE>
 
                                     -14-

          Customary abbreviations may be used in the name of a Holder of a
Security or an assignee, such as:  TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

21. Governing Law.
    ------------- 

          This Security shall be governed by, and construed in accordance with,
the laws of the State of New York without giving effect to applicable principles
of conflicts of laws to the extent that the application of the laws of another
jurisdiction would be required thereby.

22. CUSIP Numbers.
    ------------- 

          Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities as a convenience to the Holders of the Securities.  No
representation is made as to the accuracy of such numbers as printed on the
Securities and reliance may be placed only on the other identification numbers
printed hereon.

Ladies and Gentlemen:

                We have acted as counsel to Alliance Imaging, Inc., a Delaware 
corporation (the "Company"), in connection with the preparation and filing with 
the Securities and Exchange Commission (the "Commission") of the Registration 
Statement of the Company on Form S-2, as amended (File No. 333-33817) (as so 
amended, the "Registration Statement"), under the Securities Act of 1933, as 
amended (the "Act").

                This opinion is being furnished in accordance with the 
requirements of Item 601(b)(5) of Regulation S-K under the Act.

                In connection with this opinion, we have examined originals, or
copies certified or otherwise identified to our satisfaction, of such documents,
corporate records and other instruments as we have deemed necessary for the
purposes of rendering the opinions set forth below including, without
limitation, (i) the Registration Statement, (ii) the form of Indenture (the
"Indenture") to be entered into among the Company, the subsidiary guarantors of
the Company party thereto (the "Guarantors") and IBJ Schroder Bank & Trust
Company, as trustee (the "Trustee"), governing the Company's Senior Subordinated
Notes due 2005 and the Senior Subordinated Floating Rate Notes due 2005
(collectively, the "Notes"), (iii) the form of Underwriting Agreement (the
"Underwriting Agreement") to be entered into among the Company, the Guarantors
and BT Alex. Brown Incorporated and Salomon Brothers Inc (collectively, the
"Underwriters"), (iv) the Amended and Restated Certificate of Incorporation of
the Company, as amended through the date hereof, (v) the By-laws of the Company,
as amended through the date hereof, and (vi) resolutions adopted by the Board of
Directors of the Company by unanimous written consent in lieu of meetings dated
August 8, 1997 and October 10, 1997. As to certain questions of fact material to
the opinions contained herein, we have relied upon certificates or statements of
officers of the Company and certificates of public officials.

                In our examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals and
the conformity to authentic originals of all documents submitted to us as
certified or photostatic copies. In making our examination of documents executed
by parties other than the Company, we have assumed that such parties had the
power, corporate or other, to enter into and perform all obligations thereunder
and have also assumed the due

authorization by all requisite action, corporate or other, and execution and 
delivery by such parties of such documents and the validity and binding effect 
thereof.

                Based upon the foregoing, we are of the opinion as follows:

                1.  The Company is a validly existing corporation under the laws
of the State of Delaware.

                2.  The Notes have been duly authorized and, when issued and
sold to the Underwriters and paid for by them in accordance with the terms of
the Underwriting Agreement, will be validly issued and, assuming due 
authorization, execution and delivery by the Trustee, will be valid and binding 
obligations of the Company, enforceable against the Company in accordance with 
their terms, except that enforcement thereof may be subject to (i) bankruptcy, 
involvency, fradulent conveyance, reorganization, moratorium and other similar 
laws now or hereafter in effect relating to or affecting creditors' rights 
generally and (ii) general principles of equity (regardless of whether 
enforceability is considered in a proceeding in equity or at law).

                Members of our firm are admitted to the Bar of the State of New 
York and we express no opinion as to the laws of any other jurisdiction other 
than the Delaware General Corporation Law.

                We hereby consent to the filing of this opinion with the 
Commission as an exhibit to the Registration Statement.  We also consent to the 
reference to our firm under "Legal Matters" in the Registration Statement. In 
giving this consent, we do not thereby admit that we are included in the 
category of persons whose consent is required under Section 7 of the Act or the 
rules and regulations of the Commission.

                                      Very truly yours,

     specifically provided in Section 1.10(b), all Term Loans made as part of
     the same Borrowing shall at all times consist of Term Loans of the same

     thereto on such date pursuant to Section 3.03(b)(i) but after giving effect
     to any reductions thereto on or prior to such date pursuant to Section

          (i) shall be denominated in U.S. Dollars;

          (ii) shall, at the option of the Borrower, be incurred and
     maintained as, and/or converted into, Base Rate Loans or Eurodollar Loans,
     provided that (x) except as otherwise specifically provided in Section

     Loans referred to below), each of which Borrowings of Eurodollar Loans may
     only have an Interest Period of one month, and the first of which
     Borrowings may only be made on the same date as the initial Borrowing of
     Term Loans that are maintained as Eurodollar Loans, the second of which
     Borrowings may only be made on the last day of the Interest Period of the
     first such Borrowing and the third of which Borrowings may only be made on

            (iii)   may be repaid and reborrowed in accordance with the
     provisions hereof;

                                      -2-
<PAGE>
 
            (iv) shall not exceed for any Bank at any time outstanding that
     aggregate principal amount which, when added to the product of (x) such
     Bank's Adjusted RL Percentage and (y) the sum of (I) the amount of all
     Letter of Credit Outstandings (exclusive of Unpaid Drawings which are
     repaid with the proceeds of, and simultan eously with the incurrence of,
     the respective incurrence of Revolving Loans) at such time and (II) the
     aggregate principal amount of all Swingline Loans (exclusive of Swingline
     Loans which are repaid with the proceeds of, and simultaneously with the
     incurrence of, the respective incurrence of Revolving Loans) then
     outstanding, equals the Revolving Loan Commitment of such Bank at such
     time; and

            (v) shall not exceed for all Banks at any time outstanding that
     aggregate principal amount which, when added to (x) the amount of all
     Letter of Credit Outstandings (exclusive of Unpaid Drawings which are
     repaid with the proceeds of, and simultaneously with the incurrence of, the
     respective incurrence of Revolving Loans) at such time and (y) the
     aggregate principal amount of all Swingline Loans (exclusive of Swingline
     Loans which are repaid with the proceeds of, and simultan eously with the
     incurrence of, the respective incurrence of Revolving Loans) then
     outstanding, exceeds an amount equal to the Total Revolving Loan Commitment
     then in effect.

            (c)  Subject to and upon the terms and conditions herein set forth,
BTCo in its individual capacity agrees to make at any time and from time to time
on and after the Initial Borrowing Date and prior to the Swingline Expiry Date,
a loan or loans to the Borrower (each, a "Swingline Loan" and, collectively, the
"Swingline Loans"), which Swingline Loans:

            (i) shall be denominated in U.S. Dollars;

            (ii) shall be made and maintained as Base Rate Loans;

            (iii)  may be repaid and reborrowed in accordance with the
     provisions hereof;

            (iv) shall not exceed in aggregate principal amount at any time
     outstand ing, when combined with the aggregate principal amount of (x) all
     Revolving Loans made by Non-Defaulting Banks then outstanding and (y) the
     Letter of Credit Outstandings at such time, an amount equal to the Adjusted
     Total Revolving Loan Commitment at such time (after giving effect to any
     changes thereto on such date); and

            (v) shall not exceed in aggregate principal amount at any time
     outstanding the Maximum Swingline Amount.

                                      -3-
<PAGE>
 
BTCo shall not be obligated to make any Swingline Loans at a time when a Bank
Default exists unless BTCo has entered into arrangements satisfactory to it and
the Borrower to eliminate BTCo's risk with respect to the Defaulting Bank's or
Banks' participation in such Swingline Loans, including by cash collateralizing
such Defaulting Bank's or Banks' RL Percentage of the outstanding Swingline
Loans.  BTCo will not make a Swingline Loan after it has received written notice
from the Borrower or the Required Banks stating that a Default or an Event of
Default exists until such time as BTCo shall have received a written notice of
(i) rescission of such notice from the party or parties originally delivering
the same or (ii) a waiver of such Default or Event of Default from the Required
Banks.

          (d)  On any Business Day, BTCo may, in its sole discretion, give
notice to the RL Banks that its outstanding Swingline Loans shall be funded with
a Borrowing of Revolving Loans (provided that each such notice shall be deemed
                                --------                                      
to have been automatic ally given upon the occurrence of a Default or an Event
of Default under Section 10.05 or upon the exercise of any of the remedies
provided in the last paragraph of Section 10), in which case a Borrowing of
Revolving Loans constituting Base Rate Loans (each such Bor rowing, a "Mandatory
Borrowing") shall be made on the immediately succeeding Business Day by all RL
Banks pro rata based on each RL Bank's Adjusted RL Percentage, and the proceeds
      --- ----                                                                 
thereof shall be applied directly to repay BTCo for such outstanding Swingline
Loans.  Each RL Bank hereby irrevocably agrees to make Base Rate Loans upon one
Business Day's notice pursuant to each Mandatory Borrowing in the amount and in
the manner specified in the preceding sentence and on the date specified in
writing by BTCo notwithstanding (i) that the amount of the Mandatory Borrowing
may not comply with the Minimum Borrowing Amount otherwise required hereunder,

Unless the Agent shall have been notified by any Bank prior to the date of
Borrowing that such Bank does not intend to make available to the Agent its
portion of the Borrowing or Borrowings to be made on such date, the Agent may
assume that such Bank has made such amount available to the Agent on such date
of Borrowing, and the Agent, in reliance upon such assumption, may (in its sole
dis cretion and without any obligation to do so) make available to the Borrower
a correspond ing amount.  If such corresponding amount is not in fact made
available to the Agent by such Bank and the Agent has made available same to the
Borrower, the Agent shall be enti tled to recover such corresponding amount on
demand from such Bank.  If such Bank does not pay such corresponding amount
forthwith upon the Agent's demand therefor, the Agent shall promptly notify the
Borrower, and the Borrower shall immediately pay such corre sponding amount to
the Agent.  The Agent shall also be entitled to recover on demand from such Bank
or the Borrower, as the case may be, interest on such corresponding amount in

overnight Federal Funds Rate or (y) if paid by the Borrower, the then applicable
rate of interest, calculated in accordance with Section 1.08.

          (b) Nothing in this Agreement shall be deemed to relieve any Bank from
its obligation to fulfill its commitments hereunder or to prejudice any rights
which the Borrower may have against any Bank as a result of any default by such
Bank hereunder.

     preceding Business Day;

            (v) no Interest Period for a Borrowing under a Tranche shall be
     selected which would extend beyond the respective Maturity Date for such

     Periods which will expire after such date, when added to the Stated Amount
     of all Letters of Credit which by their terms expire after such date, will
     be in excess of the Total Revolving Loan Commitment as the same will be in
     effect after giving effect to the respective Scheduled Commitment
     Reduction; and

     principal amount of such Term Loans which have Interest Periods which will
     expire after such date will be in excess of the aggregate principal amount
     of such Term Loans then outstanding less the aggregate amount of such
     required Scheduled Repayment.

Borrowing of Eurodollar Loans, the Borrower has failed to elect, or is not
permitted to elect, a new Interest Period to be applicable to the respective
Borrowing of Eurodollar Loans as provided above, the Borrower shall be deemed to
have elected to convert such Borrowing into a Borrowing of Base Rate Loans
effective as of the expiration date of such current Interest Period.

     order or request (whether or not hav ing the force of law), or in the
     interpretation or administration thereof and including the introduction of
     any new law or governmental rule, regulation, guideline, order or request,
     such as, for example, but not limited to, (A) a change in the basis of
     taxation of payment to any Bank of the principal of or interest on such
     Eurodollar Loans or any other amounts payable hereunder (except for changes
     with respect to any tax imposed on, or determined by reference to, the net
     income, net profits or capital (including branch profits tax) of such Bank
     or any franchise tax based on the net income or net profits of such Bank
     pursuant to the laws of the jurisdiction in which such Bank is organized,
     or in which such Bank's principal office or applicable lending office is
     located or any subdivision thereof or therein), or (B) a change in official
     reserve requirements, but, in all events, excluding reserves required under
     Regulation D to the extent included in the computation of the Eurodollar
     Rate and/or (y) other circumstances affecting such Bank, the interbank
     Eurodollar market or the position of such Bank in such market; or

            (iii)  at any time since the date of this Agreement, that the making
     or con tinuance of any Eurodollar Loan has become unlawful by compliance by
     such Bank with any law, governmental rule, regulation, guideline or order
     (or would conflict with any governmental rule, regulation, guideline,
     request or order not having the force of law but with which such Bank
     customarily complies even though the failure to comply therewith would not
     be unlawful), or has become impracticable as a result of a contingency
     occurring after the date of this Agreement which materially and adversely
     affects the interbank Eurodollar market;

then, and in any such event, such Bank (or the Agent in the case of clause (i)
above) shall promptly give notice (by telephone confirmed in writing) to the
Borrower and (except in the case of clause (i)) to the Agent of such
determination (which notice the Agent shall promptly transmit to each of the
other Banks).  Thereafter, (x) in the case of clause (i) above, Eurodollar Loans
shall no longer be available until such time as the Agent notifies the Borrower
and the Banks that the circumstances giving rise to such notice by the Agent no
longer exist, and any Notice of Borrowing or Notice of Conversion given by the
Bor rower with respect to Eurodollar Loans which have not yet been incurred
(including by way of conversion) shall be deemed rescinded by the Borrower, (y)
in the case of clause (ii)

above, the Borrower agrees, subject to the provisions of Section 13.18 (to the
extent applicable), to pay to such Bank, upon written demand therefor, such
additional amounts (in the form of an increased rate of, or a different method
of calculating, interest or otherwise as such Bank in its sole discretion shall
determine) as shall be required to com pensate such Bank for such increased
costs or reductions in amounts received or receivable hereunder but without
duplication of any payments due under Section 4.04 (a written notice as to the
additional amounts owed to such Bank, showing in reasonable detail the basis for
the calculation thereof, submitted to the Borrower by such Bank shall, absent
manifest error, be final and conclusive and binding upon all parties hereto,
although the failure to give any such notice shall not release or diminish any
of the Borrower's obligations to pay additional amounts pursuant to this Section
1.10(a) upon the subsequent receipt of such notice) and (z) in the case of
clause (iii) above, the Borrower shall take one of the actions specified in
Section 1.10(b) as promptly as possible and, in any event, within the time
period required by law.

          (b)  At any time that any Eurodollar Loan is affected by the
circumstances described in Section 1.10(a)(ii) or (iii), the Borrower may (and
in the case of a Eurodollar Loan affected pursuant to Section 1.10(a)(iii), the
Borrower shall) either (i) if the affected Eurodollar Loan is then being made
pursuant to a Borrowing, cancel said Borrowing by giving the Agent telephonic
notice (confirmed promptly in writing) thereof on the same date that the
Borrower was notified by a Bank pursuant to Section 1.10(a)(ii) or (iii)), or
(ii) if the affected Eurodollar Loan is then outstanding, upon at least three
Business Days' notice to the Agent, require the affected Bank to convert each
such Eurodollar Loan into a Base Rate Loan (which conversion, in the case of the
circumstance described in Section 1.10(a)(iii), shall occur no later than the
last day of the Interest Period then applicable to such Eurodollar Loan or such
earlier day as shall be required by applicable law); provided, that if more than
                                                     --------                   
one Bank is affected at any time, then all affected Banks must be treated the
same pursuant to this Section 1.10(b).

          (c)  If any Bank shall have determined that after the date hereof, the
adop tion or effectiveness of any applicable law, rule or regulation regarding
capital adequacy, or any change therein, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by such Bank or any corporation controlling such Bank with any request or
directive regarding capital adequacy (whether or not having the force of law) of
any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Bank's or such other corporation's
capital or assets as a consequence of such Bank's Commitment or Commitments
hereunder or its obligations hereunder to a level below that which such Bank or
such other corporation could have achieved but for such adoption, effectiveness,
change or compliance (taking into con sideration such Bank's or such other
corporation's policies with respect to capital ade quacy), then from time to
time, upon written demand by such Bank (with a copy to the

                                      -13-

Agent), accompanied by the notice referred to in the last sentence of this
clause (c), the Borrower agrees, subject to the provisions of Section 13.18 (to
the extent applicable), to pay to such Bank such additional amount or amounts as
will compensate such Bank or such other corporation for such reduction in the
rate of return to such Bank or such other corporation.  Each Bank, upon
determining in good faith that any additional amounts will be payable pursuant
to this Section 1.10(c), will give prompt written notice thereof to the Borrower
(a copy of which shall be sent by such Bank to the Agent), which notice shall
set forth in reasonable detail the basis of the calculation of such additional
amounts, although the failure to give any such notice shall not release or
diminish the Borrower's obligations to pay additional amounts pursuant to this
Section 1.10(c) upon the subsequent receipt of such notice.  A Bank's reasonable
good faith determination of compensation owing under this Section 1.10(c) shall,
absent manifest error, be final and conclusive and binding on all the parties
hereto.

          1.11  Compensation.  The Borrower agrees, subject to the provisions of
                ------------                                                    
Section 13.18 (to the extent applicable), to compensate each Bank, promptly upon
its writ ten request (which request shall set forth in reasonable detail the
basis for requesting such compensation), for all losses, expenses and
liabilities (including, without limitation, any loss, expense or liability
incurred by reason of the liquidation or reemployment of deposits or other funds
required by such Bank to fund its Eurodollar Loans) which such Bank may sustain:
(i) if for any reason (other than a default by such Bank or the Agent) a
Borrowing of, or conversion from or into, Eurodollar Loans does not occur on a
date specified there for in a Notice of Borrowing or Notice of Conversion given
by the Borrower (whether or not withdrawn by the Borrower or deemed withdrawn
pursuant to Section 1.10(a)); (ii) if any repayment (including any repayment
made pursuant to Section 4.01 or 4.02 or as a result of an acceleration of the
Loans pursuant to Section 10 or as a result of the replacement of a Bank
pursuant to Section 1.13 or 13.12(b)) or conversion of any Euro dollar Loans of
the Borrower occurs on a date which is not the last day of an Interest Period
applicable thereto; (iii) if any prepayment of any Eurodollar Loans is not made
on any date specified in a notice of prepayment given by the Borrower; or (iv)
as a con sequence of (x) any other default by the Borrower to repay its
Eurodollar Loans when required by the terms of this Agreement or (y) an election
made by the Borrower pursuant to Section 1.10(b).  Each Bank's calculation of
the amount of compensation owing pursuant to this Section 1.11 shall be made in
good faith.  A Bank's basis for requesting compensation pursuant to this Section
1.11 and a Bank's calculation of the amount thereof, shall, absent manifest
error, be final and conclusive and binding on all parties hereto.

          1.12  Change of Lending Office.  Each Bank agrees that, upon the occur
                ------------------------                                        
rence of any event giving rise to the operation of Section 1.10(a)(ii) or (iii),
1.10(c), 2.05 or 4.04 with respect to such Bank, it will, if requested by the
Borrower, use reasonable efforts (subject to overall policy considerations of
such Bank) to designate another lending office for any Loans or Letters of
Credit affected by such event; provided, that such desig-
                               --------

nation is made on such terms that, in the sole judgment of such Bank, such Bank
and its lending office suffer no economic, legal or regulatory disadvantage,
with the object of avoid ing the consequences of the event giving rise to the
operation of any such Section.  Nothing in this Section 1.12 shall affect or
postpone any of the obligations of the Borrower or the right of any Bank
provided in Section 1.10, 2.05 or 4.04.

          1.13  Replacement of Banks.  (x)  If any Bank becomes a Defaulting
                --------------------                                        
Bank, (y) upon the occurrence of any event giving rise to the operation of
Section 1.10(a)(ii) or (iii), Section 1.10(c), Section 2.05 or Section 4.04 with
respect to any Bank which results in such Bank charging to the Borrower
increased costs in a material amount in excess of those being generally charged
by the other Banks or (z) in the case of a refusal by a Bank to consent to a
proposed change, waiver, discharge or termination with respect to this Agreement
which has been approved by the Required Banks as provided in Section 13.12(b),
the Borrower shall have the right, in accordance with Section 13.04(b), if no
Default or Event of Default then exists or would exist after giving effect to
such replace ment, to replace such Bank (the "Replaced Bank") with one or more
other Eligible Transferee or Transferees, none of whom shall constitute a
Defaulting Bank at the time of such replacement (collectively, the "Replacement
Bank") and each of whom shall be reason ably acceptable to the Agent or, at the
option of the Borrower, to replace only (a) the Revolving Loan Commitment (and
outstandings pursuant thereto) of the Replaced Bank with an identical Revolving
Loan Commitment provided by the Replacement Bank or (b) in the case of a
replacement as provided in Section 13.12(b) where the consent of the respective
Bank is required with respect to less than all Tranches of its Loans or
Commitments, the Commitments and/or outstanding Loans of such Bank in respect of
each Tranche where the consent of such Bank would otherwise be individually

     connection therewith, shall pay to (x) the Replaced Bank in respect thereof
     an amount equal to the sum of (A) an amount equal to the principal of, and

     respective Tranche or Tranches being replaced) of the Replaced Bank, (B) an
     amount equal to all Unpaid Drawings (unless there are no Unpaid Drawings

     Bank (other than those (a) specifically described in clause (i) above in
     respect of which the assignment purchase price has been, or is concurrently
     being, paid, but including all amounts, if any, owing under Section 1.11 or
     (b) relating to any Tranche of Loans and/or Commitments of the respective

          SECTION 2.  Letters of Credit.
                      -----------------

          2.01  Letters of Credit.  (a)  Subject to and upon the terms and
                -----------------                                         
conditions herein set forth, the Borrower may request a Letter of Credit Issuer
at any time and from time to time on or after the Initial Borrowing Date and
prior to the tenth Business Day (or

                                      -16-
<PAGE>
 
the 30th day in the case of Trade Letters of Credit) preceding the Revolving
Loan Maturity Date to issue, (x) for the account of the Borrower and for the
benefit of any holder (or any trustee, agent or other similar representative for
any such holders) of L/C Supportable Indebtedness, irrevocable standby letters
of credit in a form customarily used by such Letter of Credit Issuer or in such
other form as has been approved by such Letter of Credit Issuer (each such
standby letter of credit, a "Standby Letter of Credit") in support of such L/C
Supportable Indebtedness and (y) for the account of the Borrower and for the
benefit of sellers of goods to the Borrower or any Subsidiary Guarantor in the
ordinary course of business, irrevocable sight trade letters of credit in a form
customarily used by such Letter of Credit Issuer or in such other form as has
been approved by such Letter of Credit Issuer (each such trade letter of credit,
a "Trade Letter of Credit," and each such Standby Letter of Credit and Trade
Letter of Credit, a "Letter of Credit" and, collectively, the "Letters of
Credit").

          (b)  Subject to and upon the terms and conditions set forth herein,
each Letter of Credit Issuer hereby agrees that it will, at any time and from
time to time on and after the Initial Borrowing Date and prior to the tenth
Business Day (or the 30th day in the case of Trade Letters of Credit) preceding
the Revolving Loan Maturity Date, following its receipt of the respective Letter
of Credit Request, issue for the account of the Borrower one or more Letters of
Credit, (x) in the case of Trade Letters of Credit, in support of trade
obligations of the Borrower or any Subsidiary Guarantor that arise in the
ordinary course of business or (y) in the case of Standby Letters of Credit, in
support of such L/C Support able Indebtedness as is permitted to remain
outstanding hereunder.  Notwithstanding the foregoing, no Letter of Credit
Issuer shall be under any obligation to issue any Letter of Credit if at the
time of such issuance:

            (i) any order, judgment or decree of any governmental authority or
     arbi trator shall purport by its terms to enjoin or restrain such Letter of
     Credit Issuer from issuing such Letter of Credit or any requirement of law
     applicable to such Letter of Credit Issuer or any request or directive
     (whether or not having the force of law) from any governmental authority
     with jurisdiction over such Letter of Credit Issuer shall prohibit, or
     request that such Letter of Credit Issuer refrain from, the issuance of
     letters of credit generally or such Letter of Credit in particular or shall
     impose upon such Letter of Credit Issuer with respect to such Letter of
     Credit any restriction or reserve or capital requirement (for which such
     Letter of Credit Issuer is not otherwise compensated) not in effect on the
     date hereof, or any unreimbursed loss, cost or expense which was not
     applicable, in effect or known to such Letter of Credit Issuer as of the
     date hereof and which such Letter of Credit Issuer in good faith deems
     material to it; or

            (ii) such Letter of Credit Issuer shall have received written notice
     from the Borrower or the Required Banks prior to the issuance of such
     Letter of Credit

                                      -17-
<PAGE>
 
     of the type described in clause (vi) of Section 2.01(c) or the last
     sentence of Section 2.02(b).

          (c)  Notwithstanding the foregoing, (i) no Letter of Credit shall be
issued the Stated Amount of which, when added to the Letter of Credit
Outstandings (exclusive of Unpaid Drawings which are repaid on the date of, and
prior to the issuance of, the respective Letter of Credit) at such time, would
exceed either (x) $15,000,000 or (y) when added to the aggregate principal
amount of all Revolving Loans made by the Non-Defaulting Banks and then
outstanding and all Swingline Loans then outstanding, the Adjusted Total
Revolving Loan Commitment at such time; (ii) (x) each Standby Letter of Credit
shall have an expiry date occurring not later than one year after such Standby
Letter of Credit's date of issuance, provided, that any such Standby Letter of
                                     --------                                 
Credit may be extendable for successive periods of up to one year, but not
beyond the tenth Business Day preceding the Revolving Loan Maturity Date, on
terms acceptable to the Letter of Credit Issuer and (y) each Trade Letter of
Credit shall have an expiry date occurring not later than 180 days after such
Trade Letter of Credit's date of issuance; (iii) (x) no Standby Letter of Credit
shall have an expiry date occurring later than the tenth Business Day preceding
the Revolving Loan Maturity Date and (y) no Trade Letter of Credit shall have an
expiry date occurring later than 30 days prior to the Revolving Loan Maturity
Date; (iv) each Letter of Credit shall be denominated in U.S. Dollars; (v) the
Stated Amount of each Letter of Credit shall not be less than $100,000 or such
lesser amount as is acceptable to the respective Letter of Credit Issuer; and
(vi) no Letter of Credit Issuer will issue any Letter of Credit after it has
received written notice from the Borrower or the Required Banks stating that a
Default or an Event of Default exists until such time as such Letter of Credit
Issuer shall have received a written notice of (x) rescission of such notice
from the party or parties originally delivering the same or (y) a waiver of such
Default or Event of Default by the Required Banks.

          (d)  Notwithstanding the foregoing, in the event a Bank Default
exists, no Letter of Credit Issuer shall be required to issue any Letter of
Credit unless the respective Letter of Credit Issuer has entered into
arrangements satisfactory to it and the Borrower to eliminate such Letter of
Credit Issuer's risk with respect to the participation in Letters of Credit of
the Defaulting Bank or Banks, including by cash collateralizing such Defaulting
Bank's or Banks' Adjusted RL Percentage of the Letter of Credit Outstandings, as
the case may be.

          2.02  Letter of Credit Requests.  (a)  Whenever the Borrower desires
                -------------------------                                     
that a Letter of Credit be issued, the Borrower shall give the Agent and the
respective Letter of Credit Issuer written notice thereof prior to 12:00 Noon
(New York time) at least five Business Days (or such shorter period as may be
acceptable to the respective Letter of Credit Issuer) prior to the proposed date
of issuance (which shall be a Business Day) which written notice shall be in the
form of Exhibit C (each, a "Letter of Credit Request").  Each

                                      -18-
<PAGE>
 
Letter of Credit Request shall include any other documents as such Letter of
Credit Issuer customarily requires in connection therewith.

          (b)  The making of each Letter of Credit Request shall be deemed to be
a representation and warranty by the Borrower that such Letter of Credit may be
issued in accordance with, and it will not violate the requirements of, Section
2.01(c).  Unless the respective Letter of Credit Issuer has received notice from
the Required Banks before it issues a Letter of Credit that one or more of the
applicable conditions specified in Section 5 or 6, as the case may be, are not
then satisfied, or that the issuance of such Letter of Credit would violate
Section 2.01(c), then such Letter of Credit Issuer may issue the requested
Letter of Credit for the account of the Borrower in accordance with such Letter
of Credit Issuer's usual and customary practice.

          2.03  Letter of Credit Participations.  (a)  Immediately upon the
                -------------------------------                            
issuance by a Letter of Credit Issuer of any Letter of Credit, such Letter of
Credit Issuer shall be deemed to have sold and transferred to each other RL
Bank, and each such RL Bank (each, a "Participant") shall be deemed irrevocably
and unconditionally to have purchased and re ceived from such Letter of Credit
Issuer, without recourse or warranty, an undivided inter est and participation,
to the extent of such Participant's Adjusted RL Percentage, in such Letter of
Credit, each substitute Letter of Credit, each drawing made thereunder and the
obligations of the Borrower under this Agreement with respect thereto (although
Letter of Credit Fees shall be payable directly to the Agent for the account of
the RL Banks as provided in Section 3.01(b) and the Participants shall have no
right to receive any portion of any Facing Fees with respect to such Letters of
Credit) and any security therefor or guaranty pertaining thereto.  Upon any
change in the Revolving Loan Commitments or the Adjusted RL Percentages of the
RL Banks pursuant to Section 1.13 or 13.04(b) or as a result of a Bank Default,
it is hereby agreed that, with respect to all outstanding Letters of Credit and
Unpaid Drawings with respect thereto, there shall be an automatic adjustment to
the participations pursuant to this Section 2.03 to reflect the new Adjusted RL
Percentages of the assigning and assignee Bank or of all RL Banks, as the case
may be.

          (b)  In determining whether to pay under any Letter of Credit, no
Letter of Credit Issuer shall have any obligation relative to the Participants
other than to determine that any documents required to be delivered under such
Letter of Credit have been delivered and that they appear to substantially
comply on their face with the requirements of such Letter of Credit.  Any action
taken or omitted to be taken by any Letter of Credit Issuer under or in
connection with any Letter of Credit issued by it if taken or omitted in the
absence of gross negligence or willful misconduct, shall not create for such
Letter of Credit Issuer any resulting liability.

          (c)  In the event that any Letter of Credit Issuer makes any payment
under any Letter of Credit issued by it and the Borrower shall not have
reimbursed such amount

                                      -19-
<PAGE>
 
in full to the Letter of Credit Issuer pursuant to Section 2.04(a), such Letter
of Credit Issuer shall promptly notify the Agent, and the Agent shall promptly
notify each Participant of such failure, and each such Participant shall
promptly and unconditionally pay to the Agent for the account of such Letter of
Credit Issuer, the amount of such Participant's Adjusted RL Percentage of such
payment in U.S. Dollars and in same day funds.  If the Agent so notifies any
Participant required to fund a payment under a Letter of Credit prior to 11:00
A.M. (New York time) on any Business Day, such Participant shall make available
to the Agent at the Payment Office for the account of the respective Letter of
Credit Issuer such Participant's Adjusted RL Percentage of the amount of such
payment on such Business Day in same day funds (and, to the extent such notice
is given after 11:00 A.M. (New York time) on any Business Day, such Participant
shall make such payment on the immediately following Business Day).  If and to
the extent such Participant shall not have so made its Adjusted RL Percentage of
the amount of such payment available to the Agent for the account of the
respective Letter of Credit Issuer, such Participant agrees to pay to the Agent
for the account of such Letter of Credit Issuer, forthwith on demand such
amount, together with interest thereon, for each day from such date until the
date such amount is paid to the Agent for the account of the Letter of Credit
Issuer at the overnight Federal Funds Rate.  The failure of any Participant to
make available to the Agent for the account of the respective Letter of Credit

Credit on the date required, as specified above, but no Participant shall be
responsible for the failure of any other Participant to make available to the

bursement obligation as to which the Agent has received for the account of such
Letter of Credit Issuer any payments from the Participants pursuant to clause
(c) above, such Letter of Credit Issuer shall pay to the Agent and the Agent
shall promptly pay to each Participant which has paid its Adjusted RL Percentage
thereof, in U.S. Dollars and in same day funds, an amount equal to such
Participant's Adjusted RL Percentage of the principal amount thereof and
interest thereon accruing after the purchase of the respective participations.

          (e)  Each Letter of Credit Issuer shall, promptly after each issuance
of, or amendment or modification to, a Standby Letter of Credit issued by it,
give the Agent, each Participant and the Borrower written notice of the issuance
of, or amendment or modification to, such Standby Letter of Credit, which notice
shall be accompanied by a copy of the Standby Letter of Credit or Standby
Letters of Credit issued by it and each such amendment or modification thereto.

each Participant a report setting forth for such preceding calendar month the
aggregate daily Stated Amount available to be drawn under all outstanding Trade

          (g)  The obligations of the Participants to make payments to the Agent
for the account of the respective Letter of Credit Issuer with respect to
Letters of Credit issued by it shall be irrevocable and not subject to
counterclaim, set-off or other defense or any other qualification or exception
whatsoever and shall be made in accordance with the terms and conditions of this
Agreement under all circumstances, including, without limitation, any of the
following circumstances:

     Agent, any Letter of Credit Issuer, any Bank, or other Person, whether in
     connection with this Agreement, any Letter of Credit, the transactions
     contemplated herein or any unrelated transactions (including any underlying
     transaction between the Borrower or any of its Subsidiaries and the
     beneficiary named in any such Letter of Credit);

             (iii)  any draft, certificate or other document presented under the
     Letter of Credit proving to be forged, fraudulent, invalid or insufficient
     in any respect or any statement therein being untrue or inaccurate in any
     respect;

             (iv) the surrender or impairment of any security for the
     performance or observance of any of the terms of any of the Credit
     Documents; or

issued by it (each such amount so paid or disbursed until reimbursed, an "Unpaid
Drawing") immediately after,

                                      -21-

and in any event on the date of such payment or disbursement, with interest on
the amount so paid or disbursed by such Letter of Credit Issuer, to the extent
not reimbursed prior to 1:00 P.M. (New York time) on the date of such payment or
disbursement, from and including the date paid or disbursed to but not including
the date such Letter of Credit Issuer is reimbursed therefor at a rate per annum
which shall be the Applicable Margin for Revolving Loans maintained as Base Rate
Loans as in effect from time to time (plus an additional 2% per annum if not
reimbursed by the third Business Day after the date of such payment or
disbursement), such interest also to be payable on demand; provided, that it is
                                                           --------

clause (a) shall not be required to be given if a Default or an Event of Default
under such Section 10.05 shall have occurred and be continuing (in which case

disbursement made by it under any Letter of Credit issued by it, although the
failure of, or delay in, giving any such notice shall not release or diminish
the obligations of the Borrower under this Section 2.04(a) or under any other
Section of this Agreement.

          (b)  The Borrower's obligation under this Section 2.04 to reimburse
the respective Letter of Credit Issuer with respect to drawings on Letters of
Credit (including, in each case, interest thereon) shall be absolute and
unconditional under any and all circum stances and irrespective of any setoff,
counterclaim or defense to payment which the Borrower or any of its Subsidiaries
may have or have had against such Letter of Credit Issuer, the Agent or any
Bank, including, without limitation, any defense based upon the failure of any
drawing under a Letter of Credit issued by it to conform to the terms of the
Letter of Credit or any nonapplication or misapplication by the beneficiary of
the proceeds of such drawing; provided, however, that the Borrower shall not be

obligated to reimburse such Letter of Credit Issuer for any wrongful payment
made by such Letter of Credit Issuer under a Letter of Credit issued by it as a
result of acts or omissions constituting willful mis conduct or gross negligence
on the part of such Letter of Credit Issuer as determined by a court of
competent jurisdiction.

          2.05  Increased Costs.  If after the Effective Date, any Letter of
                ---------------                                             
Credit Issuer or any Participant determines that the adoption or effectiveness
of any applicable law, rule or regulation, order, guideline or request or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority, central bank or com parable agency charged with the
interpretation or administration thereof, or compliance by any Letter of Credit
Issuer or any Participant with any request or directive (whether or not having
the force of law) by any such authority, central bank or comparable agency shall
either (i) impose, modify or make applicable any reserve, deposit, capital

Issuer or such Participant's participation therein (except as contemplated by
Section 4.04), or (ii) impose on any Letter of Credit Issuer or any Participant
any other conditions directly or indirectly affecting this Agreement, any Letter
of Credit or such Participant's participation therein; and the result of any of
the foregoing is to increase the cost to such Letter of Credit Issuer or such
Participant of issuing, maintaining or participating in any Letter of Credit, or
to reduce the amount of any sum received or receivable by such Letter of Credit
Issuer or such Participant hereunder or reduce the rate of return on its capital
with respect to Letters of Credit, then, upon written demand to the Borrower by
such Letter of Credit Issuer or such Participant (a copy of which notice shall
be sent by such Letter of Credit Issuer or such Participant to the Agent),
accompanied by the certificate described in the last sentence of this Section
2.05, the Borrower agrees, subject to the provisions of Section 13.18 (to the
extent applicable), to pay to such Letter of Credit Issuer or such Participant
such additional amount or amounts as will compensate such Letter of Credit

as the case may be (a copy of which certificate shall be sent by such Letter of
Credit Issuer or such Participant to the Agent), setting forth in reasonable
detail the basis for the determination of such additional amount or amounts
necessary to compensate such Letter of Credit Issuer or such Participant as
aforesaid shall be final and conclusive and binding on the Borrower absent
manifest error, although the failure to deliver any such certificate shall not
release or diminish the Borrower's obliga tions to pay additional amounts
pursuant to this Section 2.05 upon subsequent receipt of such certificate.

Facing Fee with respect to each Letter of Credit be less than $500; it being
agreed that (x) on the date of issuance of any Letter of Credit and on each
anniversary thereof prior to the termination of such Letter of Credit, if $500
will exceed the amount of Facing Fees that will accrue with respect to such
Letter of Credit for the immediately succeeding 12-month  period, the full $500
shall be payable on the date of issuance of such Letter of Credit and on each
such anniversary thereof prior to the termination of such Letter of Credit and
(y) if on the date of the termination of any Letter of Credit, $500 actually
exceeds the amount of Facing Fees paid or payable with respect to such Letter of
Credit for the period beginning on the date of the issuance thereof (or if the
respective Letter of Credit has been outstanding for more than one year, the
date of the last anniversary of the issuance thereof occurring prior to the
termination of such Letter of Credit) and ending on the date of the termination
thereof, an amount equal to such excess shall be paid as additional Facing Fees
with respect to such Letter of Credit on the next date upon which Facing Fees
are payable in accordance with the immediately succeeding sentence.  Except as
provided in the immediately preceding sentence, accrued Facing Fees shall be due
and payable quarterly in arrears on each Quarterly Payment Date and upon the
first day on or after the termination of the Total Revolving Loan Commitment
upon which no Letters of Credit remain outstanding.

          (d)  The Borrower shall pay directly to each Letter of Credit Issuer
upon each issuance of, payment under, and/or amendment of, a Letter of Credit
issued by such Letter of Credit Issuer such amount as shall at the time of such
issuance, payment or amendment be the administrative charge which such Letter of
Credit Issuer is customarily charging for issuances of, payments under or
amendments of, letters of credit issued by it.

          (e)  The Borrower shall pay to the Agent, for its own account, such
other fees as may be agreed to in writing from time to time between the Borrower
and the Agent, when and as due.

             (f)  All computations of Fees shall be made in accordance with
Section 13.07(b).

Bank as in effect immediately before giving effect to such reduction minus (B)
such RL Bank's Adjusted RL Percentage of the aggregate principal amount of
Swingline Loans then outstanding and (z) any partial reduction to the Total

this Section 4.02(f) in the form des cribed in clause (x) above and also
certifying its determination as required by preceding clause (b) and certifying
the sufficiency of business interruption insurance as required by succeeding
clause (d), and (d) an Authorized Officer of the Borrower has delivered to the
Agent such evidence as the Agent may reasonably request in form and substance
reasonably satisfactory to the Agent establishing that the Borrower has
sufficient business interruption insurance and that the Borrower will receive
payment thereunder in such amounts and at such times as are necessary to satisfy

Event and continuing through the completion of the replacement or restoration of
respective properties or assets, then the entire amount of the proceeds of such
Recovery Event and not just the portion in excess of $2,500,000 shall be
deposited with the Agent pursuant to a cash collateral arrangement reasonably
satisfactory to the Agent whereby such proceeds shall be disbursed to the
Borrower from time to time as needed to pay or reimburse the Borrower or such
Subsidiary actual costs incurred by it in connection with the replacement or
restoration of the respective properties or assets (pursuant to such
certification requirements as may be established by the Agent), provided further

Required Banks may direct the Agent (in which case the Agent shall, and is

used within 360 days after the date of the respective Recovery Event or (B) if
committed to be used within 360 days after the date of receipt of such net
proceeds and not so used within 18 months after the date of respective Recovery
Event then, in either such case, such remaining portion not used or committed to
be used in the case of preceding clause (A) and not used in the case of
preceding clause (B) shall be applied on the date occurring 360 days after the
date of the respective Recovery Event in the case of clause (A) above or the
date occurring 18 months after the date of the respec tive Recovery Event in the
case of clause (B) above as a mandatory repayment and/or commitment reduction in

(d), (e), (f) and (g) in accordance with this Section 4.02(h) shall be applied
(i) first, to repay the outstanding principal amount of Term Loans and (ii)
second, to the extent in excess of the amounts required to be applied pursuant
to preceding clause (i), to reduce the Total Revolving Loan Commitment (it being
understood and agreed that (x) the amount of any reduction to the Total
Revolving Loan Commitment shall be deemed to be an application of proceeds for
purposes of this Section 4.02(h) even though cash is not actually applied and
(y) any cash received by the Borrower or such Subsidiary will be retained by
such Person except to the extent that such cash is otherwise required to be
applied as provided

                                      -33-

in Section 4.02(a) as a result of any reduction to the Total Revolving Loan
Commitment).  All repayments or commitment reductions, as the case may be, of
(x) outstanding Term Loans on the one hand and (y) Revolving Loan Commitments,
on the other hand, pursuant to Sections 4.02(c), (d), (e), (f) or (g) shall be
applied to reduce the then remaining Scheduled Repayments (in the case of
preceding clause (x)) or Scheduled Commitment Reductions (in the case of
preceding clause (y)), on a pro rata basis (based upon the then remaining

          (i)  With respect to each repayment of Loans required by this Section
4.02, the Borrower may designate the Types of Loans of the respective Tranche
which are to be repaid and, in the case of Eurodollar Loans, the specific
Borrowing or Borrowings of the respective Tranche pursuant to which made,
provided that:  (i) repayments of Eurodollar Loans pursuant to this Section 4.02

may only be made on the last day of an Interest Period applicable thereto unless
(x) all Eurodollar Loans of the respective Tranche with Interest Periods ending
on such date of required repayment and all Base Rate Loans of the respective
Tranche have been paid in full and/or (y) concurrently with such repayment, the
Borrower pays all breakage costs and other amounts owing to each Bank pursuant
to Section 1.11; (ii) if any repayment of Eurodollar Loans made pursuant to a
single Borrow ing shall reduce the outstanding Eurodollar Loans made pursuant to
such Borrowing to an amount less than the Minimum Borrowing Amount applicable
thereto, such Borrowing shall be converted at the end of the then current
Interest Period into a Borrowing of Base Rate Loans; and (iii) each repayment of
any Tranche of Loans made pursuant to a Borrowing shall be applied pro rata
                                                                   --- ----
among such Tranche of Loans.  In the absence of a designation by the Borrower as
described in the preceding sentence, the Agent shall, subject to the above, make
such designation in its sole discretion with a view, but no obligation, to
minimize breakage costs owing under Section 1.11.  Notwithstanding the foregoing
provisions of this Section 4.02, if at any time the mandatory repayment of Loans
pursuant to Section 4.02(c), (d), (e), (f) or (g) would result, after giving
effect to the procedures set forth in this clause (i) above, in the Borrower
incurring breakage costs under Section 1.10 as a result of Eurodollar Loans
being repaid other than on the last day of an Interest Period applicable thereto
(any such Eurodollar Loans, "Affected Loans"), the Borrower may elect, by
written notice to the Agent, to have the provisions of the following sentence be
applicable.  At the time any Affected Loans are otherwise required to be prepaid
the Borrower may elect to deposit 100% (or such lesser percentage elected by the
Borrower as not being repaid) of the principal amounts that otherwise would have
been paid in respect of the Affected Loans with the Agent to be held as security
for the obligations of the Borrower hereunder pursuant to a cash collateral
agreement to be entered into in form and substance satisfactory to the Agent,
with such cash collateral to be released from such cash collateral account (and
applied to repay the principal amount of such Eurodollar Loans) upon each
occurrence thereafter of the last day of an Interest Period applicable to
Eurodollar Loans of the respective Facility (or such earlier date or dates as
shall be

                                      -34-

requested by the Borrower), with the amount to be so released and applied on the
last day of each Interest Period to be the amount of such Eurodollar Loans to
which such Interest Period applies (or, if less, the amount remaining in such
cash collateral account).

          (j)  Notwithstanding anything to the contrary contained elsewhere in
this Agreement, (i) all then outstanding Swingline Loans shall be repaid in full
on the Swingline Expiry Date and (ii) all other then outstanding Loans shall be
repaid in full on the respective Maturity Date for such Loans.

          4.03  Method and Place of Payment.  Except as otherwise specifically
                ---------------------------                                   
pro vided herein, all payments under this Agreement or any Note shall be made to
the Agent for the ratable account of the Bank or Banks entitled thereto not
later than 12:00 Noon (New York time) on the date when due and shall be made in
immediately available funds and in U.S. Dollars at the Payment Office.  Any
payments under this Agreement or under any Note which are made later than 12:00
Noon (New York time) shall be deemed to have been made on the next succeeding
Business Day.  Whenever any payment to be made here under or under any Note
shall be stated to be due on a day which is not a Business Day, the due date
thereof shall be extended to the next succeeding Business Day and, with respect
to payments of principal, interest shall be payable during such extension at the
applicable rate in effect immediately prior to such extension.

          4.04  Net Payments.  (a)  All payments made by the Borrower hereunder
                ------------                                                   
or under any Note will be made without setoff, counterclaim or other defense.
Except as provided in Section 4.04(b), all such payments will be made free and
clear of, and without deduction or withholding for, any present or future taxes,
levies, imposts, duties, fees, assessments or other charges of whatever nature
now or hereafter imposed by any jurisdic tion or by any political subdivision or
taxing authority thereof or therein with respect to such payments (but
excluding, except as provided in the second succeeding sentence, any tax imposed
on or measured by the net income, net profits or capital (including branch
profits tax) of a Bank pursuant to the laws of the jurisdiction in which it is
organized or the jurisdiction in which the principal office or applicable
lending office of such Bank is located or any subdivision thereof or therein)
and all interest, penalties or similar liabilities with respect to such
nonexcluded taxes, levies, imposts, duties, fees, assessments or other charges
(all such nonexcluded taxes, levies, imposts, duties, fees, assessments or other
charges being referred to collectively as "Taxes").  If any Taxes are so levied
or imposed, the Borrower agrees to pay the full amount of such Taxes, and such
additional amounts as may be necessary so that every payment of all amounts due
under this Agreement or under any Note, after withholding or deduction for or on
account of any Taxes, will not be less than the amount provided for herein or in
such Note.  If any amounts are payable in respect of Taxes pursuant to the
preceding sentence, the Borrower agrees to reimburse each Bank, upon the written
request of such Bank, for taxes imposed on or measured by the net income, net
profits or capital (including branch profits tax) of such Bank pursuant to the

                                      -35-
<PAGE>
 
laws of the jurisdiction in which such Bank is organized or in which the
principal office or applicable lending office of such Bank is located or under
the laws of any political subdivision or taxing authority of any such
jurisdiction in which such Bank is organized or in which the principal office or
applicable lending office of such Bank is located and for any withholding of
taxes as such Bank shall determine are payable by, or withheld from, such Bank
in respect of such amounts so paid to or on behalf of such Bank pursuant to the
preceding sentence and in respect of any amounts paid to or on behalf of such
Bank pursuant to this sentence.  The Borrower will furnish to the Agent within
45 days after the date the payment of any Taxes is due pursuant to applicable
law certified copies of tax receipts evidencing such payment by the Borrower.
The Borrower agrees to indemnify and hold harmless each Bank, and reimburse such
Bank upon its written request, for the amount of any Taxes so levied or imposed
and paid by such Bank.

          (b)  Each Bank party to this Agreement on the Effective Date hereby
represents that, as of the Effective Date, all payments of principal, interest,
and fees to be made to it by the Borrower pursuant to this Agreement will be
totally exempt from withholding of United States federal tax.  Each Bank that is
not a United States person (as such term is defined in Section 7701(a)(30) of
the Code) for U.S. Federal income tax purposes agrees to deliver to the Borrower
and the Agent on or prior to the Effective Date, or in the case of a Bank that
is an assignee or transferee of an interest under this Agreement pursuant to
Section 1.13 or 13.04 (unless the respective Bank was already a Bank hereunder
immediately prior to such assignment or transfer), on the date of such
assignment or transfer to such Bank, (i) two accurate and complete original
signed copies of Internal Revenue Service Form 4224 or 1001 (or successor forms)
certifying to such Bank's entitlement to a complete exemption from United States
withholding tax with respect to payments to be made under this Agreement and
under any Note, or (ii) if the Bank is not a "bank" within the meaning of
Section 881(c)(3)(A) of the Code and cannot deliver either Internal Revenue
Service Form 1001 or 4224 pursuant to clause (i) above, (x) a certificate
substantially in the form of Exhibit D (any such certificate, a "Section
4.04(b)(ii) Certificate") and (y) two accurate and complete original signed
copies of Internal Revenue Service Form W-8 (or successor form) certifying to
such Bank's entitlement to a complete exemption from United States withholding
tax with respect to payments of interest to be made under this Agreement and
under any Note.  In addition, each Bank agrees that from time to time after the
Effective Date, when a lapse in time or change in circumstances renders the
previous certification obsolete or inaccurate in any material respect, and that
upon the Borrower's reasonable request after the occurrence of any other event
requiring the delivery of a Form 1001 and Form 4224 in addition to or in
replacement of the forms previously delivered, it will deliver to the Borrower
and the Agent two new accurate and complete original signed copies of Internal
Revenue Service Form 4224 or 1001, or Form W-8 and a Section 4.04(b)(ii)
Certificate, as the case may be, and such other forms as may be required in
order to confirm or establish the entitlement of such Bank to a continued
exemption from or reduction in United States withholding tax with respect to
payments

                                      -36-
<PAGE>
 
under this Agreement and any Note, or it shall immediately notify the Borrower
and the Agent of its inability to deliver any such Form or Certificate in which
case such Bank shall not be required to deliver any such Form or Certificate
pursuant to this Section 4.04(b).  Notwithstanding anything to the contrary
contained in Section 4.04(a), but subject to Section 13.04(b) and the
immediately succeeding sentence, (x) the Borrower shall be entitled, to the
extent it is required to do so by law, to deduct or withhold income or similar
taxes imposed by the United States (or any political subdivision or taxing
authority thereof or therein) from interest, fees or other amounts payable
hereunder for the account of any Bank which is not a United States person (as
such term is defined in Section 7701(a)(30) of the Code) for U.S. Federal income
tax purposes to the extent that such Bank has not provided to the Borrower U.S.
Internal Revenue Service Forms that establish a complete exemption from such
deduction or withholding and (y) the Borrower shall not be obligated pursuant to
Section 4.04(a) hereof to gross-up payments to be made to a Bank in respect of
income or similar taxes imposed by the United States if (I) such Bank has not
provided to the Borrower the Internal Revenue Service Forms required to be
provided to the Borrower pursuant to this Section 4.04(b) or (II) in the case of
a payment, other than interest, to a Bank described in clause (ii) above, to the
extent that such Forms do not establish a complete exemption from withholding of
such taxes.  Notwithstanding anything to the contrary contained in the preceding
sentence or elsewhere in this Section 4.04 and except as set forth in Section
13.04(b), the Borrower agrees to pay additional amounts and to indemnify each
Bank in the manner set forth in Section 4.04(a) (without regard to the identity
of the jurisdiction requiring the deduction or withholding) in respect of any
Taxes deducted or withheld by them as described in the immediately preceding
sentence as a result of any changes after the Effective Date in any applicable
law, treaty, governmental rule, regulation, guideline or order, or in the
interpretation thereof, relating to the deducting or withholding of such Taxes
(or, if later, the date such Bank became party to this Agreement).  The Borrower
shall not be required to pay any additional amounts or indemnification under
Section 4.04(a) to any Bank to the extent that the obligation to pay such
additional amounts or indemnification would not have arisen but for the
representation set forth in the first sentence of Section 4.04(b) above made by
the Bank not being true.

          (c)  If the Borrower pays any additional amount under this Section
4.04 to a Bank and such Bank determines in its sole discretion that it has
actually received or realized in connection therewith any refund or any
reduction of, or credit against, its Tax liabilities in or with respect to the
taxable year in which the additional amount is paid, such Bank shall pay to the
Borrower an amount that the Bank shall, in its sole discretion, determine is
equal to the net benefit, after tax, which was obtained by the Bank in such year
as a consequence of such refund, reduction or credit.

          (d)  Each Bank shall use reasonable efforts (consistent with legal and
regulatory restrictions and subject to overall policy considerations of such
Bank) (i) to file any certificate or document or to furnish any information as
reasonably requested by the

                                      -37-
<PAGE>
 
Borrower pursuant to any applicable treaty, law or regulation or (ii) to
designate a different applicable lending office of such Bank, if the making of
such filing or the furnishing of such information or the designation of such
other lending office would avoid the need for or reduce the amount of any
additional amounts payable by the Borrower and would not, in the sole discretion
of such Bank, be disadvantageous to such Bank.

          (e) The provisions of this Section 4.04 are subject to the provisions
of Section 13.18 (to the extent applicable).

case of the Pro Forma Balance Sheet, presents a good faith estimate of the

consolidated pro forma financial condition of the Borrower (after giving effect

financial statements, to normal year-end adjustments.  All such financial
statements (other than the aforesaid Pro Forma Balance Sheet) have been prepared
                                     --- -----

incurred in the ordinary course of business and commitments to purchase
Healthcare Units) with respect to the Borrower or any of its Subsidiaries of any
nature whatsoever (whether absolute, accrued, contingent or otherwise and
whether or not due) which, either individually or in the aggregate, could
reasonably be expected to be material to the Borrower and its Subsidiaries taken
as a whole or the Borrower and (ii) the Borrower does not know of any basis for
the assertion against the Borrower or any of its Subsidiaries of any such
liability or obligation which, either individually or in the aggregate, are or
would be reasonably likely to have, a Material Adverse Effect.

finan cial statements referred to in Section 7.10(b), and are based on good
faith estimates and assumptions made by the management of the Borrower.  On the
Initial Borrowing Date, such management believed that the Projections were
reasonable and attainable.  There is no fact known to the Borrower or any of its
Subsidiaries which could reasonably be expected to have a Material Adverse

Section 9.03), in favor of the Collateral Agent.  No filings or recordings are
required in order to perfect the security interests created under any Security
Document except for filings or recordings required in connection with any such
Security Document which shall have been made on or prior to the Initial
Borrowing Date as contemplated by Section 5.11 or on or prior to the execution
and delivery thereof as contemplated by Sections 8.11, 8.12 and 9.15.

the Credit Parties agree to jointly and severally reimburse the Agent or the
Collateral Agent, as the case may be, for all costs and expenses of procuring
such insurance.

cause each of its Subsidiaries to, comply with all applicable statutes,
regulations and orders of, and all applicable restrictions imposed by, all

Subsidiaries, or transport or permit the transportation of Hazardous Materials
to or from any such Real Property, unless the failure to comply with the
requirements specified in clause (i) or (ii) above, either individually or in
the aggregate, would not reasonably be expected to have a Material Adverse
Effect.  If the Borrower or any of its Subsidiaries, or any tenant or occupant
of any Real Property owned or operated by the Borrower or any of its
Subsidiaries, cause or permit any intentional or unintentional act or omission
resulting in the presence or Release of any Hazardous Material (except in
compliance with applicable Environmental Laws), the Borrower agrees to
undertake, and/or to cause any of its Subsidiaries, tenants or occupants to
undertake, at their sole expense, any clean up, removal, remedial or other
action required pursuant to Environmental Laws to remove and clean up any
Hazardous Materials from any Real Property except where the failure to do so

hereafter owned or operated by the Borrower or any of its Subsidiaries, prepared
by an environmental consulting firm approved by the Agent, addressing the

more of the total combined voting power of all classes of capital stock of such
Foreign Subsidiary entitled to vote, (ii) the entering into by such Foreign
Subsidiary of a security agreement in substantially the form of the Security
Agreement and (iii) the entering into by such Foreign Subsidiary of a guaranty
in substantially the form of the Subsidiaries Guar anty, in any such case could
reasonably be expected to cause (I) the undistributed earnings of such Foreign
Subsidiary as determined for Federal income tax purposes to be treated as a
deemed dividend to such Foreign Subsidiary's United States parent for Federal
income tax purposes or (II) other material adverse Federal income tax
consequences to the Credit Parties, then in the case of a failure to deliver the
evidence described in clause (i) above, that portion of such Foreign
Subsidiary's outstanding capital stock so issued by such Foreign Subsidiary, in
each case not theretofore pledged pursuant to the Pledge Agreement shall be
pledged to the Collateral Agent for the benefit of the Secured Creditors

similar form, if needed), granting the Secured Creditors a security interest in
all of such Foreign Subsidiary's assets and securing the Obligations of the
Borrower under the Credit Documents and under any Interest Rate Protection Agree
ment or Other Hedging Agreement and, in the event the Subsidiaries Guaranty

Foreign Subsidiary there under, and in the case of a failure to deliver the
evidence described in clause (iii) above, such Foreign Subsidiary shall execute
and deliver the Subsidiaries Guaranty (or another

                                      -66-

guaranty in substantially similar form, if needed), guaranteeing the Obligations
of the Borrower under the Credit Documents and under any Interest Rate
Protection Agreement or Other Hedging Agreement, in each case to the extent that
the entering into of such Security Agreement or Subsidiaries Guaranty is
permitted by the laws of the respective foreign jurisdiction and with all
documents delivered pursuant to this Section 8.12 to be in form and substance
reasonably satisfactory to the Agent.

Banks, each Credit Party shall directly or indirectly own 100% of the capital
stock or other equity interests of each of their respective Subsidiaries.

          8.14  Permitted Acquisitions.  (a)  Subject to the provisions of this
                ----------------------

to time effect Permitted Acquisitions, so long as (in each case except to the
extent the Required Banks otherwise specifically agree in writing in the case of
a specific Permitted Acquisition):  (i) no Default or Event of Default shall be
in existence at the time of the consummation of the proposed Permitted
Acquisition or immediately after giving effect thereto; (ii) the Borrower shall

(in the case of Section 9.11, giving effect to the last sentence appearing
therein) for the period of four (except in the case of any determination of
Consolidated EBITDA for purposes of such Sections, which shall be measured on a
two-quarter annualized basis as provided in the definition thereof) consecutive
fiscal quarters (taken as one accounting period) most recently ended prior to
the date of such Permitted Acquisition (each, a "Calculation Period"), on a Pro
                                                                            ---

Permitted Acquisitions theretofore consummated after the first day of such
Calculation Period) had occurred on the first day of such Calculation Period,
and such recalculations shall show that such financial covenants would have been
complied with if the Permitted Acquisition had occurred on the first day of such
Calculation Period (for this purpose, if the first day of the respective
Calculation Period occurs prior to the Initial Borrowing Date, calculated as if
the covenants contained in said Sections 9.08, 9.09, 9.10 and 9.11 (in the case
of Section 9.11, giving effect to the last sentence appearing therein) had been
applicable from the first day of the Calculation Period); (iv) based on good
faith projections prepared by the Borrower for the period from the date of the

extent that any of the foregoing is not paid by the Borrower or any of its
Subsidiaries; provided, that no Bank shall be liable to the Agent for the
              --------                                                   
payment of any portion of such liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
solely from the gross negligence or willful misconduct of the Agent.  If any
indemnity furnished to the Agent for any purpose shall, in the opinion of the
Agent be insufficient or become impaired, the Agent may call for additional
indemnity and cease, or not commence, to do the acts indem nified against until
such additional indemnity is furnished.  The agreements in this Section 12.07
shall survive the payment of all Obligations.

        12.08  Agent in its Individual Capacity.  The Agent and its affiliates
               --------------------------------                               
may make loans to, accept deposits from and generally engage in any kind of
business with the Borrower and its Subsidiaries as though the Agent were not the
Agent hereunder.  With respect to the Loans made by it and all Obligations owing
to it, the Agent shall have the same rights and powers under this Agreement as
any Bank and may exercise the same as though it were not the Agent and the terms
"Bank" and "Banks" shall include the Agent in its individual capacity.

        12.09  Holders.  The Agent may deem and treat the payee of any Note as
               -------                                                        
the owner thereof for all purposes hereof unless and until a written notice of
the assignment, transfer or endorsement thereof, as the case may be, shall have
been filed with the Agent.  Any request, authority or consent of any Person or
entity who, at the time of making such request or giving such authority or
consent, is the holder of any Note shall be conclusive and binding on any
subsequent holder, transferee, assignee or indorsee, as the case may be, of such
Note or of any Note or Notes issued in exchange therefor.

        12.10  Resignation of the Agent.  (a)  The Agent may resign from the
               ------------------------                                     
performance of all its functions and duties hereunder and/or under the other
Credit Documents at any time by giving 30 Business Days' prior written notice to
the Borrower and the Banks.  Such resignation shall take effect upon the
appointment of a successor Agent pursuant to clauses (b) and (c) below or as
otherwise provided below.

        (b)  Upon any such notice of resignation, the Required Banks shall
appoint a successor Agent hereunder or thereunder who shall be a commercial bank
or trust company reasonably acceptable to the Borrower.

        (c)  If a successor Agent shall not have been so appointed within such
30 Business Day period, the Agent, with the consent of the Borrower (which
consent shall not be unreasonably withheld or delayed), shall then appoint a
successor Agent who shall serve as Agent hereunder or thereunder until such
time, if any, as the Required Banks appoint a successor Agent as provided above.

        (d)  If no successor Agent has been appointed pursuant to clause (b) or
(c) above by the 30th Business Day after the date such notice of resignation was
given by the Agent, the Agent's resignation shall become effective and the
Required Banks shall thereafter perform all the duties of the Agent hereunder
and/or under any other Credit Document until such time, if any, as the Banks
appoint a successor Agent as provided above.

        13.02  Right of Setoff.  In addition to any rights now or hereafter
               ---------------

        13.04  Benefit of Agreement.  (a)  This Agreement shall be binding upon

and inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto; provided, however, the Borrower may not assign or
                               --------  -------                                
transfer any of its rights, obligations or interest hereunder or under any other
Credit Document without the prior written consent of the Banks and, provided
                                                                    --------
further, that, although any Bank may transfer, assign or grant participations in
- -------                                                                         
its rights hereunder, such Bank shall remain a "Bank" for all purposes hereunder
(and may not transfer or assign all or any portion of its Commitments hereunder
except as provided in Section 13.04(b)) and the transferee, assignee or
participant, as the case may be, shall not constitute a "Bank" hereunder and,
                                                                             
provided further, that no Bank shall transfer or grant any participation under
- ----------------                                                              
which the participant shall have rights to approve any amendment to or waiver of
this Agreement or any other Credit Document except to the extent such amendment
or waiver would (i) extend the final scheduled maturity of any Loan, Note or
Letter of Credit (unless such Letter of Credit is not extended beyond the
Revolving Loan Maturity Date) in which such participant is participating, or
reduce the rate or extend the time of payment of interest or Fees thereon
(except in connection with a waiver of applicability of any post-default
increase in interest rates) or reduce the principal amount thereof, or increase
the amount of the participant's participation over the amount thereof then in
effect (it being understood that a waiver of any Default or Event of Default or
of a mandatory reduction in the Total Commitment shall not constitute a change
in the terms of such participation, that an increase in any Commitment or Loan
shall be permitted without the consent of any participant if the participant's
parti cipation is not increased as a result thereof and that any amendment or
modification to the financial definitions in this Agreement shall not constitute
a reduction in any rate of interest or fees for purposes of this clause (i)),
(ii) consent to the assignment or transfer by the Borrower of any of its rights
and obligations under this Agreement or (iii) release all or substantially all
of the Collateral under all of the Security Documents (except as expressly
provided in the Security Documents) supporting the Loans hereunder in which such
parti cipant is participating.  In the case of any such participation, the
participant shall not have any rights under this Agreement or any of the other
Credit Documents (the participant's rights against such Bank in respect of such
participation to be those set forth in the agreement executed by such Bank in
favor of the participant relating thereto) and all amounts payable by the
Borrower hereunder shall be determined as if such Bank had not sold such
participation.

        (b)  Notwithstanding the foregoing, any Bank (or any Bank together with
one or more other Banks) may (x) assign all or a portion of its Revolving Loan
Commitment (and related outstanding Obligations hereunder) and/or its
outstanding Term Loans to (i) its parent company and/or any affiliate of such
Bank which is at least 50% owned by such Bank or its parent company or to one or
more Banks or (ii) in the case of any Bank that is a fund that invests in bank
loans, any other fund that invests in bank loans and is managed by the same
investment advisor of such Bank or by an Affiliate of such investment advisor or
(y) assign all, or if less than all, a portion equal to at least $5,000,000 in
the aggregate for the assigning Bank or assigning Banks, of such Revolving Loan
Commitments (and related outstanding Obligations hereunder) and outstanding
principal amount of Term Loans to one or more Eligible Transferees (treating (x)
any fund that invests in bank loans and (y) any other fund that invests in bank
loans and is managed by the same investment advisor as such fund or by an
Affiliate of such investment advisor, as a single Eligible Transferee), each of
which assignees shall become a party to this Agreement as a Bank by execution of
an Assignment and Assumption Agreement, provided that (i) at such time Schedule
                                        --------                               
I shall be deemed modified to reflect the Revolving Loan Commitments and/or
outstanding Term Loans, as the case may be, of such new Bank and of the existing
Banks, (ii) upon surrender of the old Notes (or the furnishing of a standard
indemnity letter from the respective assigning Bank in respect of any lost
Notes), new Notes will be issued, at the Borrower's expense, to such new Bank
and to the assigning Bank, such new Notes to be in conformity with the
requirements of Section 1.05 (with appropriate modifications) to the extent
needed to reflect the revised Revolving Loan Commitments and/or outstanding Term
Loans, as the case may be, (iii) the consent of the Agent and, so long as no
Default or Event of Default is then in existence, the Borrower shall be required
in connection with any assignment to an Eligible Transferee pursuant to clause
(y) of this Section 13.04(b) (which consent, in each case, shall not be
unreasonably withheld or delayed), (iv) the consent of each Letter of Credit
Issuer shall be required in connection with any Revolving Loan Commitments
pursuant to clause (y) of this Section 13.04(b) (which consent shall not be
unreasonably withheld or delayed) and (v) the Agent shall receive at the time of
each assignment, from the assigning or assignee Bank, the payment of a non-
refundable assignment fee of $3,500 and, provided further, that such transfer or
                                         -------- -------                       
assignment will not be effective until recorded by the Agent on the Register
pursuant to Section 13.17.  To the extent of any assignment pursuant to this
Section 13.04(b), the assigning Bank shall be relieved of its obligations
hereunder with respect to its assigned Revolving Loan Commitment and/or
outstanding Term Loans.  At the time of each assignment pursuant to this Section
13.04(b) to a Person which is not already a Bank hereunder and which is not a
United States person (as such term is defined in Section 7701(a)(30) of the
Code) for Federal income tax purposes, the respective assignee Bank shall
provide to the Borrower and the Agent the appropriate Internal Revenue Service
Forms (and, if applicable a Section 4.04(b)(ii) Certificate) described in
Section 4.04(b).  To the extent that an assignment of all or any portion of a
Bank's Revolving Loan Commitment and outstanding Obligations pursuant to Section
1.13 or this Section 13.04(b) would, due to circumstances existing at

                                     -137-
<PAGE>
 
the time of such assignment, result in increased costs under Section 1.10, 1.11,
2.05 or 4.04 from those being charged by the respective assigning Bank prior to
such assignment, then the Borrower shall not be obligated to pay such increased
costs (although the Borrower shall be obligated to pay any other increased costs
of the type described above resulting from changes after the date of the
respective assignment).  Notwithstanding anything to the contrary contained
above, at any time after the termination of the Total Revolving Loan Commitment,
if any Revolving Loans or Letters of Credit remain outstanding, assignments may
be made as provided above, except that the respective assignment shall be of a
portion of the outstanding Revolving Loans of the respective RL Bank and its
participation in Letters of Credit and its obligation to make Mandatory
Borrowings, although any such assignment effected after the termination of the
Total Revolving Loan Commitment shall not release the assigning RL Bank from its
obligations as a Participant with respect to outstanding Letters of Credit or to
fund its share of any Mandatory Borrowing (although the respective assignee may
agree, as between itself and the respective assigning RL Bank, that it shall be
responsible for such amounts).

        (c)  Nothing in this Agreement shall prevent or prohibit any Bank or
BTCo from pledging its Loans and Notes hereunder to a Federal Reserve Bank in
support of borrowings made by such Bank from such Federal Reserve Bank and, with
the consent of the Agent, any Bank which is a fund may pledge all or any portion
of its Notes or Loans to its trustee in support of its obligations to its
trustee.  No pledge pursuant to this clause (c) shall release the transferor
Bank from any of its obligations hereunder.

        13.05  No Waiver; Remedies Cumulative.  No failure or delay on the part
               ------------------------------                                  
of the Agent or any Bank in exercising any right, power or privilege hereunder
or under any other Credit Document and no course of dealing between any Credit
Party and the Agent or any Bank shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, power or privilege hereunder or under
any other Credit Document preclude any other or further exercise thereof or the
exercise of any other right, power or privilege hereunder or thereunder.  The
rights and remedies herein expressly provided are cumulative and not exclusive
of any rights or remedies which the Agent or any Bank would otherwise have.  No
notice to or demand on any Credit Party in any case shall entitle any Credit
Party to any other or further notice or demand in similar or other circumstances
or constitute a waiver of the rights of the Agent or the Banks to any other or
further action in any circum stances without notice or demand.

        13.06  Payments Pro Rata.  (a)  The Agent agrees that promptly after its
               -----------------                                                
receipt of each payment from or on behalf of any Credit Party in respect of any
Obligations of such Credit Party, it shall, except as otherwise provided in this
Agreement, distribute such payment to the Banks (other than any Bank that has
consented in writing to waive its pro rata share of such payment) pro rata based
                                  --- ----                        --- ----      
upon their respective shares, if any, of the Obligations with respect to which
such payment was received.

                                     -138-
<PAGE>
 
        (b)  Each of the Banks agrees that, if it should receive any amount
hereunder (whether by voluntary payment, by realization upon security, by the
exercise of the right of setoff or banker's lien, by counterclaim or cross
action, by the enforcement of any right under the Credit Documents, or
otherwise) which is applicable to the payment of the princi pal of, or interest
on, the Loans, Unpaid Drawings or Fees, of a sum which with respect to the
related sum or sums received by other Banks is in a greater proportion than the
total of such Obligation then owed and due to such Bank bears to the total of
such Obligation then owed and due to all of the Banks immediately prior to such
receipt, then such Bank receiving such excess payment shall purchase for cash
without recourse or warranty from the other Banks an interest in the Obligations
of the respective Credit Party to such Banks in such amount as shall result in a
proportional participation by all of the Banks in such amount; provided, that if
                                                               --------         
all or any portion of such excess amount is thereafter recovered from such Bank,
such purchase shall be rescinded and the purchase price restored to the extent
of such recovery, but without interest.

        13.07  Calculations; Computations.  (a)  The financial statements to be
               --------------------------                                      
furnished to the Banks pursuant hereto shall be made and prepared in accordance
with GAAP consistently applied throughout the periods involved (except as set
forth in the notes thereto or as otherwise disclosed in writing by the Borrower
to the Banks); provided, that except as otherwise specifically provided herein,

all computations determining compliance with Sections 4.02, 8.14 and 9,
including definitions used therein shall, in each case, utilize accounting
principles and policies in effect at the time of the preparation of, and in
conformity with those used to prepare, the December 31, 1996 financial
statements of the Borrower delivered to the Banks pursuant to Section 7.10(b);
provided further, that (i) to the extent expressly required pursuant to the
- ----------------                                                           
provisions of this Agreement, certain calcu lations shall be made on a Pro Forma
                                                                       --- -----
Basis, (ii) to the extent compliance with any of Sections 9.08, 9.09, 9.10 or
9.11 would include periods occurring prior to the Initial Borrowing Date, such
calculation shall be adjusted on a Pro Forma Basis to give effect to the
                                   --- -----                            
Transaction as if same had occurred on the first day of the respective period
and (iii) in the case of any determinations of Consolidated Interest Expense for
any portion of any Test Period which ends prior to the Initial Borrowing Date,
all computations determining compliance with Section 9.10 shall be calculated in
accordance with the definition of Test Period contained herein.

        (b)  All computations of interest and Fees hereunder shall be made on
the actual number of days elapsed over a year of 360 days.

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

Agreement or any other Credit Document may be brought in the courts of the State
of New York or of the United States for the Southern District of New York, and,

behalf, and in respect of its property, service of any and all legal process,
summons, notices and documents which may be served in any such action or

be available to act as such, the Borrower agrees to designate a new designee,
appointee and agent in New York City on the terms and for the purposes of this
provision satisfactory to the Agent under this Agreement.  The Borrower hereby
further irrevocably waives any claim that any such courts lack jurisdiction over
the Borrower, and agrees not to plead or claim, in any legal action or
proceeding with respect to this Agreement or any other Credit Document brought

Borrower.  The Borrower further irrevocably consents to the service of process
in any such action or proceeding by the mailing of copies thereof by registered

pursuant to Section 13.03, such service to become effective 30 days after such
mailing.  The Borrower hereby irrevocably waives any objection to such service
of process and further irrevocably waives and agrees not to plead or claim in
any action or proceeding commenced hereunder or under any other Credit Document
that service of process was in any way invalid or ineffective.  Nothing herein
shall affect the right of the Agent, any Bank or the holder of any Note to serve
process in any other manner permitted by law or to commence legal proceedings or
otherwise proceed against any Credit Party in any other jurisdiction.

        (b)  The Borrower hereby irrevocably waives any objection which it may

proceedings arising out of or in connection with this Agreement or any other
Credit Document brought in the courts referred to in clause (a) above and hereby
further irrevocably waives and agrees not to plead or claim in any such court

or more Replacement Banks pursuant to Section 1.13 so long as at the time of
such replacement, each such Replacement Bank consents to the proposed change,
waiver, discharge or termination or (B) terminate such non-consenting Bank's
Revolving Loan Commitment (if such Bank's consent is required as a result of its
Revolving Loan Commitment) and/or repay each Tranche of outstanding Loans of

repaid pursuant to preceding clause (B) are immediately replaced in full at such
time through the addition of new Banks or the increase of the Revolving Loan
Commitments and/or outstanding Loans of existing Banks (who in each case must
specifically consent thereto), then in the case of any action pursuant to

proposed action) shall specifically consent thereto, provided further, that the
                                                     ----------------

not be responsible for costs arising under Section 1.10, 1.11, 2.05 or 4.04

Bank's holding or parent company in its sole discretion determines that any such

Federal regulatory body having or claiming to have jurisdiction over such Bank
or to the Federal Reserve Board or the Federal Deposit Insurance Corporation or

successors or (y) in connection with any request or requirement of any such
regulatory body, (c) as may be required or appropriate in response to any
summons or subpoena or in connection with any litigation, (d) to comply with any

               --------                                                        
this Section 13.15 to the same extent as such Bank.

        13.16  Waiver of Jury Trial.  EACH OF THE PARTIES TO THIS AGREEMENT

OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER CREDIT
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

               --------                                                       
the Borrower's agent, solely for purposes of this Section 13.17, to maintain a
register (the "Register") on which it will record the Commitments from time to
time of each of the Banks, the Loans made by each of the Banks and each
repayment in respect of the principal amount of the Loans of each Bank.  Failure
to make any such recordation, or any error in such recordation shall not affect
the Borrower's obligations in respect of such Loans.  With respect to any Bank,
the transfer of the Revolving Loan Commitment of such Bank and the rights to the
principal of, and interest on, any Loan shall not be effective until such
transfer is recorded on the Register maintained by the Agent with respect to
ownership of such Revolving Loan Commitment and Loans and prior to such
recordation all amounts owing to the transferor with respect to such Revolving
Loan Commitment and Loans shall remain

                                     -143-

part of any Revolving Loan Commitment and Loans shall be recorded by the Agent

Coincident with the delivery of such an Assignment and Assumption Agreement to
the Agent for acceptance and registration of assignment or transfer of all or
part of a Loan, or as soon thereafter as practicable, the assigning or
transferor Bank shall surrender the Note evidencing such Loan, and thereupon one
or more new Notes in the same aggregate principal amount shall be issued to the
assigning or transferor Bank and/or the new Bank.  The Borrower agrees to
indemnify the Agent from and against any and all losses, claims, damages and
liabilities of whatsoever nature which may be imposed on, asserted against or
incurred by the Agent in performing its duties under this Section 13.17.

        13.18  Limitation on Additional Amounts, etc.  Notwithstanding anything
               --------------------------------------                          
to the contrary contained in Section 1.10, 1.11, 2.05 or 4.04 of this Agreement,
unless a Bank gives notice to the Borrower that it is obligated to pay an amount
under such Section within six months after the later of (x) the date the Bank
incurs the respective increased costs, Taxes, loss, expense or liability,
reduction in amounts received or receivable or reduction in return on capital or
(y) the date such Bank has actual knowledge of its incurrence of the respective
increased costs, Taxes, loss, expense or liability, reductions in amounts
received or receivable or reduction in return on capital, then such Bank shall
only be entitled to be compensated for such amount by the Borrower pursuant to
said Section 1.10, 1.11, 2.05 or 4.04, as the case may be, to the extent of the
costs, Taxes, loss, expense or liability, reduction in amounts received or
receivable or reduction in return on capital that are incurred or suffered on or
after the date which occurs six months prior to such Bank giving notice to the
Borrower that it is obligated to pay the respective amounts pursuant to said
Section 1.10, 1.11, 2.05 or 4.04, as the case may be.  This Section 13.18 shall
have no applicability to any Section of this Agreement other than said Sections
1.10, 1.11, 2.05 and 4.04.

warranties, covenants, events of default and other agreements herein and
therein) shall be deemed modified to the extent necessary to effect the
foregoing (and to permit the taking of the actions described above within the

have been, taken within the rele vant time periods referred to in this Section

In answering any item in this Statement of Eligibility which relates to matters
peculiarly within the knowledge of the obligor and its directors or officers,
the trustee has relied upon information furnished to it by the obligor.

is based on incomplete information.

Item 2, may, however, be considered as correct unless amended by an amendment to
this Form T-1.

Pursuant to General Instruction B, the trustee has responded to Items 1, 2 and

13, the obligor is not in default under any indenture under which the applicant
is trustee.
