                                        PART I


ITEM 1.   BUSINESS.

GENERAL

    Alliance Imaging, Inc. (the Company) 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 health care providers.   The Company's magnetic resonance imaging 
("MRI") services include the provision of high technology diagnostic imaging 
systems, highly-trained technologists to operate the imaging systems, 
equipment maintenance and upgrades, the management of day-to-day operations, 
educational and marketing support, patient scheduling, billing and collection 
services, managed care contracting and professional liability insurance.  The 
Company's MRI services are provided on both a mobile, shared-user basis and 
on a full-time basis to single customers.  Since its introduction in the 
early 1980's, MRI experienced rapid growth due to wide clinical acceptance 
and is now the preferred imaging modality for many diagnostic imaging 
procedures.  The sophisticated diagnostic imaging systems provided by the 
Company produce highly detailed images of a patient's internal anatomical 
structures to aid in the diagnosis of disease or injury and the selection of 
therapy by health care providers.  The Company believes that it is one of the 
largest providers of hospital based fixed-site and shared-user MRI services 
and imaging systems in the United States.  The Company also provides computed 
axial tomography ("CT") services and imaging systems, primarily in 
California; revenues from such services and imaging systems accounted for 
approximately 5% of the Company's revenues for the year ended December 31, 
1996.

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.  Many health care providers, however, lack sufficient scan 
volume or financial resources to justify the purchase of an MRI system.  Such 
providers contract for mobile, shared-user systems or single-user, full-time 
systems to gain access to MRI technology and to provide comprehensive MRI 
services to their patients.  In addition, many health care providers, 
regardless of whether their patient utilization levels and financial 
resources justify the purchase of an MRI system, prefer to contract with the 
Company for full-time or shared-user imaging systems to:  (i) obtain the use 
of an MRI system without any capital investment or financial risk; (ii) 
retain the ability to switch system types and avoid technological risk; (iii) 
obtain MRI services in jurisdictions in which the use of the Company's 
services facilitates the procurement of regulatory approvals; (iv) avoid 
future uncertainty as to reimbursement policies; (v) eliminate the need to 
recruit, train and manage qualified technologists; (vi) outsource their 
entire MRI service to obtain 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 
December 31, 1996, the Company provided imaging systems and related 
technologists and support services to 371 customers (316 for MRI services and 
70 for CT services; some customers contract for both modalities) consisting 
primarily of medium-sized hospitals (i.e., hospitals with 100-250 beds).  
Currently, the Company provides services and equipment to customers in 36 
states.

    The Company's strategy includes providing new or upgraded MRI systems to 
both mobile and single user customers under long-term contracts, expanding 
the number of systems in fixed-site locations, replacing certain older mobile 
systems with more technologically advanced systems and increasing the 
utilization of its existing systems.  The Company's business plan calls for 
targeting customers in smaller and medium-sized cities and towns because the 
Company believes that customers in those locations have a desire or need for 
MRI services and systems but generally do not have the same access to MRI 
services and systems as customers in larger metropolitan areas.  The Company 
actively targets smaller and medium-sized hospitals, clinics, multi-physician 
specialty groups, health maintenance organizations and governmental 
installations for future business.  The Company also plans to expand into 
regions of the country not currently served via internal growth as well as by 
acquisition of regional MRI providers.

    New applications for MRI technology are continuously being researched. 
Several contrast agents for use in imaging of the abdomen and the central 
nervous system are in various stages of Food and Drug Administration 
approval. Management anticipates that such developments will significantly 
broaden the technical capabilities of MRI.  MRI is also becoming an 
increasingly viable diagnostic tool in the field of angiography and 
cardiology. New applications may increase usage of MRI by

                                       2

<PAGE>

hospitals and other health care facilities, including health maintenance 
organizations and multi-physician specialty groups.  Smaller clinics or 
medical centers, which may not be able to afford to purchase, install and 
operate MRI systems, provide another potential customer base.

    The profitability of the Company is based substantially on the degree to 
which the Company can utilize its imaging systems.  Currently, the Company 
has its MRI systems 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.

    Part of the Company's strategy is to retain existing customers with high 
scan volumes and system usage by providing them with full-time MRI systems 
under long-term, fee-per-scan contracts in either existing mobile vans or 
relocatable, modular buildings.  Because initiation of MRI services at a new 
customer's location is generally associated with lower scan volume and 
revenue, the Company's financial performance is temporarily adversely 
affected by non-renewal or early termination of customer contracts even if 
such contracts are replaced relatively quickly.  The Company is subject to 
the risk that customers will cease using the Company's MRI services in order 
to purchase or lease their own MRI systems.  The Company disposed of most of 
its older MRI systems in 1994 and 1995 and had no systems out of service at 
December 31, 1996.  While most of the Company's business is provided on a 
contract basis to health care providers, a portion is being performed in a 
provider, or direct patient billing, mode.  For the year ended December 31, 
1996, no single contract customer accounted for more than three percent of 
revenues.

JOINT VENTURE

    The Company, through a subsidiary, is a partner in a joint venture at 
December 31, 1996. This partnership operates a fixed-site MRI system at a 
large hospital in Georgia.  It is supervised by a radiology medical group.

MARKETING

    Currently, the Company's sales force consists of 14 members who identify 
and contact candidates for the Company's services.  Direct marketing plays a 
primary role in the Company's development of new customers.  Each of the 
sales managers reports to one of five senior corporate managers who each have 
overall management and sales responsibility for a specific region of the 
country.  The Company believes that having senior managers involved in sales 
and contract negotiations enhances its ability to obtain new contracts.

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 healthcare customers and provide problem-solving 
services.  These specialists play a central role in the Company's retention 
of accounts and building of scan volume.  Management believes that targeted 
direct marketing at each hospital with assigned responsibility for support 
services is a key element for broadening the awareness of MRI technology, 
building scan volume and obtaining contract renewals.

OPERATIONS AND SCHEDULING

    The Company's seven regional offices market, manage and staff the 
operation of its imaging systems.  The Company's regional offices are located 
in:  Orange and Roseville, California; Chicago, Illinois; Colorado Springs, 
Colorado; Burlington, Connecticut; Pittsburgh, Pennsylvania; and Macon, 
Georgia.  Each region has individuals responsible for sales and operations 
management.  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, if required, are assigned to each of the 
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.

                                       3

CONTRACTS AND FEES

    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, contracts billed on a fee-per-scan 
or fee-per-day basis include the provision of technologists by the Company, 
while contracts billed on a fee-per-month basis generally do not.  Although a 
typical contract offers daily flat-rate options, most customers currently pay 
on a fee-per-scan basis.  The amount of fees under this billing method 
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 exam 
volume, or to terminate the contract if the Company is unable to realize a 
profit on the services provided.

IMAGING SYSTEMS

    The Company purchases 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 suites.  The trailers and relocatable modular
suites are designed jointly by the imaging system manufacturer and the housing
manufacturer and are designed to provide image quality identical to those found
in full-time health care facilities.

    At December 31, 1996, the Company operated 86 MRI systems and nine CT 
systems.  Of the 86 MRI systems, 67 are high-field or mid-field premium 
systems, 17 are other mid-field systems, and two are older systems (which the 
Company expects to dispose of in the next 12 to 24 months as they complete 
current contract assignments).  Further, of the 86 MRI systems, 76 are housed 
in mobile coaches and 10 are housed in relocatable modular buildings, 
generally on hospital campuses.

    Substantially all imaging systems are owned by the Company.  The Company 
periodically reviews the depreciable value of its imaging systems at least 
annually and more frequently if the facts and circumstances suggest it may be 
impaired.

    Under its arrangements with manufacturers to trade in older MRI systems 
as partial consideration for new systems, the Company sometimes operates the 
system traded-in for a period of up to several months after the new system is 
placed in service by the Company to allow the Company to fulfill existing 
contractual obligations.  Revenue associated with such traded-in systems was 
not significant in 1996.

    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.

REIMBURSEMENT AND REGULATION

    HEALTH CARE ENVIRONMENT
    National attention has been focused on rising health care costs and 
various plans have been proposed which attempt to improve the cost 
effectiveness of health care delivery in the United States.  Both government 
and private third party payers continue to seek means of reducing the cost of 
health care delivery.  The Company expects that some of the resulting 
governmental and private initiatives may benefit the Company while other 
initiatives may be detrimental to the Company.  The full impact of the 
anticipated new initiatives cannot be assessed at this time.

    REIMBURSEMENT
    The majority of the Company's revenues are derived directly from health 
care providers rather than from private insurers, other third party 
reimbursers 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 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 8% of revenue in 1996.

    Most private health care insurers, including Blue Cross and Blue Shield, 
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.  Since patient reimbursement

                                          4
<PAGE>

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").  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.  However, it is possible that DRG payment rates or other 
limits might be implemented with respect to outpatient services in the 
future.  President Clinton has proposed, as part of the fiscal year 1998 
federal budget, establishment of a prospective payment system for outpatient 
services.

    Because payments have generally been less restricted in non-hospital 
outpatient settings, there has been rapid growth in MRI units at non-hospital 
free-standing facilities which provide outpatient services.  The Department 
of Health and Human Services ("HHS"), as required by statute, has issued fee 
schedules for reimbursing physicians who treat Medicare patients.  Under 
these fee schedules, physician reimbursement for professional services is 
based on a value 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 where furnished by hospitals or 
certain other limited types of health care providers.  The Company believes 
that approximately 15% to 20% of its customers' MRI revenues are currently 
derived from Medicare patients.

    REGULATION
    Many aspects of the medical industry in the United States 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 federal government has announced its desire to reform 
America's health care system; the extent to which such reform and any new 
regulations will affect the Company's business cannot be assessed at this 
time.

    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 
respecting the rebate or division of fees.

    The Company is subject to federal and state laws which govern financial 
and other arrangements between healthcare providers.  These include the 
federal Medicare and Medicaid anti-kickback statute which prohibits 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 
or arranging of services, items or equipment for which payment may be made in 
whole or in part under the Medicare, Medicaid or federal healthcare program.  
Violation of the anti-kickback statute may result in criminal penalties and 
exclusion from the Medicare and other federal healthcare 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 
healthcare 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 healthcare 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.

                                          5
<PAGE>

    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 
statutes.  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 has structured its 
operations to comply with these federal and state physician self-referral 
laws.

    The Company believes that the Medicare and Medicaid anti-kickback 
statute, as interpreted by HHS (including through the "safe harbor" 
regulations), and the physician self-referral laws may enhance the Company's 
competitive position since many MRI service partnerships have been or may be 
required to be restructured, significantly, altered or discontinued from 
providing MRI services altogether.  In addition, especially in the last 
circumstance, the Company may be presented with attractive opportunities to 
acquire MRI systems.  However, because the anti-kickback and self-referral 
statutes are broad,  the "safe harbor" regulations narrow and the absence of 
regulations to implement Stark overall are subject to pending and future 
judicial interpretation, there is limited authority on which the Company may 
rely.  There can be no assurance that such laws will not be interpreted in 
the future in a manner inconsistent with the Company's interpretation and 
operations.

    In some states, a certificate of need ("CON") or similar regulatory 
approval is required prior to the acquisition of high-cost medical imaging 
systems or provision of medical services by the Company or its customers.  
CON regulations can limit or preclude the Company from providing diagnostic 
imaging services or systems.  The CON application process may be lengthy and 
costly.  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, since obtaining a CON provides the Company 
with a competitive advantage in obtaining and retaining customers in such 
jurisdictions.  However, to the extent states retain or expand CON 
regulations, this could provide an advantage to the Company in states where 
it operates under CON regulations or is able to provide additional services 
pursuant to such CON regulations.  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.

EXPANSION INTO NEW MODALITIES AND SERVICES

    The Company plans to expand the scope of its outsourcing offerings in 
1997 by entering new diagnostic and therapeutic modalities which can be cross 
sold to the existing customer base.  In addition, the Company manages a large 
portfolio of imaging systems providing management, operational and 
information services. The Company believes that asset management services may 
present opportunities for future expansion.

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.

EMPLOYEES

    As of December 31, 1996, the Company had 383 employees, of whom 
approximately 320 were trained diagnostic imaging technologists, patient 
coordinators, technical support staff or other field operations personnel.  
None of the Company's employees are represented by a labor organization and 
the Company is not aware of any actively seeking such organization.  
Relations with employees have been good.

COMPETITION

    The market for diagnostic imaging services and imaging systems is highly 
competitive.  In addition to direct competition from other contract 
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 imaging equipment 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 and employ the necessary technologists.  The 
Company competes against other contract providers on the basis of quality of 
services, quality and magnetic field strength of imaging systems, price, 
availability and reliability.

COMPANY HISTORY

    The Company's predecessors, an English partnership and an affiliated 
California corporation, began operation in 1983 by providing mobile CT 
services in southern California.  Mobile MRI services commenced in 1985.  The 
Company's predecessors were merged into Alliance Imaging plc, an English 
public limited company, in 1985.  The Company was incorporated in Delaware in 
May 1987 and in July 1987 acquired all the outstanding stock of Alliance 
Imaging plc.

    The Company's common stock was publicly traded from August 1987 until 
November 1988, when the Company was acquired in a going-private transaction 
(the "Acquisition").  The Acquisition was accomplished through stock purchase 
agreements with individual stockholders and a cash tender offer by Casper 
Acquisition Corp., a wholly-owned subsidiary of CTFG Acquisition Corp., which 
was formed and owned by DLJ Capital Corp. and certain of the Company's 
current stockholders and members of management, including Richard N. Zehner, 
the Company's Chairman, President and Chief Executive Officer.  In November 
1991, the Company completed its second initial public offering of common 
stock and has been a publicly traded company since that time.

ITEM 2.  PROPERTIES.

    For its executive and principal administrative offices, the Company 
occupies approximately 13,500 square feet of space in an office building in 
Orange, California.  The Company also leases space for its regional offices, 
and 15,600 square foot operations warehouse in California.  The Company has 
entered into an agreement to lease approximately 15,000 square feet of office 
space in Anaheim, California and will move its executive and principal 
administrative offices in May 1997.

ITEM 3.  LEGAL PROCEEDINGS.

    The Company is from time to time involved in routine litigation 
incidental to the conduct of its business.  The Company believes that no 
litigation pending against it will have a material adverse effect on its 
consolidated financial position or results of operations.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

    No matters were submitted to a vote of the Company's stockholders during 
the fourth quarter of 1996.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

    The Company's financial performance depends substantially upon the scan 
volume of its magnetic resonance imaging (MRI) systems.  Revenues are 
generally derived from one to eight year contracts with health care 
providers.  Since a majority of the Company's expenses are fixed, increased 
revenues as a result of higher scan volumes significantly improve the 
Company's profitability. Conversely, lower scan volumes result in lower 
profitability.

    Among other things, the Company is subject to the risk that customers 
will cease using the Company's MRI services upon expiration of contracts to 
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.

    The health care industry is highly regulated and very competitive.  The 
current health care environment is characterized by cost containment 
pressures which management 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.  However, in many 
cases higher scan volumes associated with new customer contracts justify 
lower scan prices and such contracts do not adversely impact the Company's 
revenues and profitability.  Although the Company has experienced increased 
scan volumes in 1995 and 1996, it has also had periods of declining volumes 
in prior years, and there can be no assurance that the recent positive trends 
will continue.

    The Company has implemented numerous cost containment and efficiency 
measures to reduce operating, payroll and selling, general and administrative 
costs.  It has also developed a new marketing plan to refocus and expand its 
sales and marketing efforts, and has substantially upgraded its MRI systems 
over the last three years.  Additionally, the Company continues to evaluate 
the profitability of certain existing customer relationships with a view 
toward eliminating unprofitable accounts and redeploying or otherwise 
disposing of certain equipment.

    The Company intends to continue its ongoing equipment trade-in and 
upgrade program which has substantially improved the marketability and 
productivity of its MRI and computed axial tomography (CT) systems.  The 
Company intends to either trade in older, less marketable MRI systems in 
connection with new system purchases, or to upgrade them with new computers, 
software and coils to enable its MRI systems to remain competitive in the 
marketplace.

    On April 26, 1996, the Company acquired all of the outstanding shares of 
Royal Medical Health Services, Inc. (Royal) of Pittsburgh, Pennsylvania, and 
certain related assets.  Like the Company, Royal is a provider of 
comprehensive MRI services to hospitals. The Company issued 3,876 shares of 
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.  
The acquisition has been accounted for as a purchase and, accordingly, the 
results of operations of Royal have been included in the Company's 
consolidated financial statements from the date of acquisition.  In addition, 
the Company completed several smaller acquisitions in 1995 and 1996, which 
were also accounted for as purchases.

COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995 
- --Revenues for 1996 were $68,482,000, an increase of $10,417,000, or 17.9%, 
over 1995.  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 revenue 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 revenue 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 
from 5.8 in 1995.  Management attributes the non-Royal 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 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 payers; obtaining contracts with customers 
that have high scan volumes which justify lower scan prices; and many 
customers achieving discount price levels by virtue of attaining higher scan 
volumes.  Revenue under fixed fee contracts increased $893,000, or 43.8%, 
resulting from an increased number of MRI systems under such arrangements.  
Other revenue increased $891,000 primarily as a result of the Company selling 
its investment in London-based Alliance Medical, Ltd. and recording a gain of 
$750,000.  CT revenue increased $632,000, or 21.8%, primarily as a result of 
the third quarter 1995 and fourth quarter 1996 acquisitions of two CT 
businesses.

    The Company 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 the Company was 85 during 1996, compared to 74 during 1995.

                                       10

    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 $1,781,000, or 15.2%, which was in line with the 
revenue increase. Equipment rental expense increased $898,000, or 60.4%.  The 
increase resulted from a higher number of rented MRI systems in operation and 
the Company's leasing of 20 new tractors in 1996.  Other operating expenses 
increased $759,000, 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 the Company'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 borrowings related to 
equipment additions.

    An income tax provision of $1,060,000 was recorded in 1996.  The 
Company's pre-tax income in 1996 is substantially offset by net operating 
loss carryforwards; however, certain federal alternative minimum taxes and 
state tax liabilities apply 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.  The Company's 1996 effective tax rate of approximately 14% of 
pre-tax income before extraordinary gains was comparable with the 1995 rate.  
At December 31, 1996, the Company 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 available to reduce future income 
tax provisions.  The Company expects its future effective tax rate to 
increase as these net operating loss carryovers are fully utilized.

    The Company'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.  Earnings per common share directly related to operations 
(excluding gains on sales of assets) totaled $0.43 in 1996, compared to $0.26 
for 1995, an increase of 65.4%.  Earnings per common share in 1996 also 
included $0.05 related to the Company's fourth quarter sale of its investment 
in Alliance Medical, Ltd.  The Company reported extraordinary gains, net of 
income taxes, in the fourth quarter of 1996 of approximately $6,300,000, or 
$0.55 per common share, on early extinguishment of debt.  In addition the 
Company recorded earnings of $0.15 per common share related to the excess of 
the carrying amount of the Series A 6% cumulative preferred stock repurchased 
over the consideration paid and other charges.  Earnings per common share 
totaled $1.18 in 1996.  The earnings per common share calculations reflect 
preferred dividend requirements of $943,000 in 1996 and $930,000 for 1995.

COMPARISON OF YEAR ENDED DECEMBER 31, 1995 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 revenue under fixed 
fee contracts and an increase in CT and other revenue totaling $125,000, 
offset by a $1,492,000, or 2.9%, decrease in scan-based MRI revenue.  The 
decrease in scan-based MRI revenue resulted from a 5.8% increase in scan 
volume offset by an 8.2% decrease in average revenue realized per MRI scan.  
Management attributes the volume increases 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.  The average number 
of scans per day for each MRI system remained steady 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 payers, as well as obtaining contracts 
with customers that have high scan volumes which justify lower scan prices.  
The increase in MRI revenue 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.

                                       11

CT and other revenue 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 the Company's full-service imaging center in Fresno, 
California as of September 30, 1995.

    The Company operated 76 MRI systems at December 31, 1995, compared to 72 
systems at December 31, 1994.  The average number of MRI systems operated by 
the Company was 74 in 1995, compared with 68.5 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 $302,000, or 2.4%, to $12,086,000 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 $54,000, or 0.6%, to $9,313,000, 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 $931,000, or 38.1%, to $1,515,000, as 
operating leases expired and the Company returned the related equipment to 
the lessor.  The leased equipment was generally replaced with low cost used 
MRI systems purchased by the Company.  Professional medical services, 
supplies, site fees and repairs expenses collectively decreased $1,387,000, 
or 31.6%, to $3,000,000, primarily as a result of reduced physician staffing 
and other cost control efforts at the Company'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 
$627,000, or 15.6%, as a result of long-term deferred incentive compensation 
costs and inflationary pressures.  Bad debt expense decreased $590,000, or 
96.9%, to $19,000 in 1995 as a result of revised billing practices and 
continuing intensive collection efforts, primarily with respect to the 
Company's retail accounts receivable.

    Interest expense of $5,053,000 in 1995 was $5,705,000, or 53.0%, lower 
than 1994 primarily as a result of the Company's comprehensive debt 
restructuring, effective as of December 31, 1994, and lower average 
outstanding debt balances in 1995.

    The Company recorded special charges totaling $13,339,000 in the fourth 
quarter of 1994 (see note 1 to financial statements).  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.  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.  The Company's 
pre-tax income in 1995 is substantially offset by net operating loss 
carryforwards; however, certain federal alternative minimum taxes and state 
tax liabilities apply 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 the 
Company'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, the Company 
had approximately $33,000,000 in federal net operating loss carryforwards 
available to offset future taxable income, subject to certain limitations.

    The Company'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 1994's net loss without the effect of the special charges and 
related tax impact.  This increase is attributable to 1995's higher operating 
profit and lower interest expense.  Earnings per common share totaled $.28 in 
1995, compared to a loss per common share of ($2.68) in 1994 (which includes 
($1.94) net loss per common share for special charges).  The 1995 earnings 
per common share calculation reflects preferred dividend requirements 
totaling $930,000 which arose as part of the Company's financial 
restructuring, effective December 31, 1994.  There were no preferred dividend 
requirements in 1994.

LIQUIDITY AND CAPITAL RESOURCES -- At December 31, 1996, cash and short-term 
investments were $10,867,000 compared to $11,128,000 at December 31, 1995, 
and the aggregate of the Company's long-term debt and senior subordinated 
debentures was $72,702,000 compared to $65,932,000 at December 31, 1995.  The 
Company maintains a $3,000,000 revolving line of credit secured by accounts 
receivable. This line, which has not been utilized, is intended to act as a 
temporary supplement to fund working capital needs.

    The Company generated $21,731,000 in net cash from operating activities 
during 1996, compared to $18,043,000 during 1995, an increase of $3,688,000, 
or 20.4%.  This cash flow was sufficient to meet the Company's debt service 
obligations and capital expenditures not financed.  During 1996, the Company 
financed $23,889,000 of capital expenditures and repaid $13,630,000 of 
long-term debt.  In addition, the Company assumed $5,532,000 of long-term 
debt in connection with the Royal acquisition and $1,135,000 of long-term 
debt in connection with the acquisition of Sun MRI Services, Inc. (see 
"Capital Expenditures" below). The Company believes its continuing cash flow 
from operations as well as its cash balances and other credit sources will be 
adequate for anticipated operating, debt service, preferred dividend and 
capital expenditure requirements.

    In November 1996, the Company arranged for the sale of all of its senior 
notes by the original holders to new owners.  In connection with the sale, 
the Company prepaid $5,300,000 of the senior notes at a discount of 
$1,810,000.  In addition, the new holders and the Company 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, the Company may (and currently expects 
to) make voluntary monthly principal and interest payments of $335,000 
through October 2002 to fully retire the notes.  The Company may also prepay 
the notes at any month end at specified discounts from their face amount.  At 
December 31, 1996 the Company's senior notes had a balance of $19,866,000.

    On December 31, 1996, the Company entered into a Bridge Loan Agreement 
(enabling the Company 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 4% convertible preferred stock.  On December 31, 1996, the Company 
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 6% redeemable preferred stock at a discount (plus 
related accrued interest and dividends).  In connection with this 
transaction, on January 2, 1997, the Company 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).  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 convertible preferred stock on or after January 1, 1998.  The 
senior note agreement contains limitations on equipment additions, incurrence 
of debt and other similar items.

    In connection with the Company's debt refinancing effective December 31, 
1996, the Company 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.  Unpaid dividends accumulate and are 
payable quarterly by the Company 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 the Company after 
December 31, 2006 .

    In connection with the Royal acquisition, the Company 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 the Company's 
option. Holders of Series C convertible preferred stock may convert their 
stock into common stock at a price of $5 per common share.

    In the event of liquidation, dissolution or winding up of the Company, 
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 Series C, D or E convertible preferred 
stock.

CAPITAL EXPENDITURES -- The Company purchased 15 new high-field MRI systems 
and upgraded 20 other MRI systems at a total approximate cost of $26,500,000 
during 1996.  Over 90% of this amount was financed by long-term 
secured loans. During 1996 the Company also disposed of 15 less 
technologically advanced mid-field MRI systems.

    In February 1996, the Company acquired four MRI systems and associated 
MRI contracts from Mobile M.R. Venture, Ltd.  In connection with the Royal 
acquisition, the Company acquired six MRI systems.  In August, the Company 
acquired all of the outstanding shares of Sun MRI Services, Inc., a northern 
California based MRI service provider.  In connection with this transaction, 
the Company obtained one MRI system and six hospital contracts. In late 
September 1996, the Company acquired certain assets and associated contracts 
from West Coast Mobile Imaging, a southern California based CT service 
provider. Although the acquisition was comparatively small, it added 16 new 
CT customers. These transactions were primarily funded with $2,850,000 from 
existing cash reserves, debt assumed and issuance of equity securities.   
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 long-term secured or unsecured financing, if 
available.

    The Company currently plans to purchase 18 new high-field MRI systems in 
1997 and plans to upgrade several existing systems, subject to obtaining 
related MRI service contracts with customers and obtaining financing for the 
equipment acquisitions.  The Company intends to use a combination of existing 
cash reserves, cash flow from operations and long-term secured equipment 
financing to finance its capital expenditures, although there can be no 
assurance that such financing will be available to the Company.  The Company 
intends to continue focusing on acquiring state-of-the-art equipment while 
disposing of older systems, and expects to dispose of most of its remaining 
older systems during 1997.

    If the Company adds MRI systems at a more rapid rate than is currently 
planned, or if it acquires additional business entities, or if the net cash 
generated by operations declines from current or anticipated levels, the 
Company could be required to raise additional capital.  However, there can be 
no assurance that the Company would be able to raise such capital, or do so 
on terms acceptable to the Company, or that consents from present lenders, if 
required, could be obtained.

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                  DECEMBER 31, 1996

1.  DESCRIPTION OF THE COMPANY AND BASIS OF FINANCIAL STATEMENT PRESENTATION

DESCRIPTION OF THE COMPANY  -- Alliance Imaging, Inc. (the Company) 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 health care providers.  Diagnostic imaging 
services are provided on both a mobile, shared-user basis as well as on a 
full-time basis to single customers.  The Company operates entirely within 
the United States and is one of the largest providers of magnetic resonance 
imaging (MRI) and computed tomography (CT) services in the country.  The 
equipment used by the Company is sophisticated and subject to accelerated 
obsolescence in the event of significant technological change.

BASIS OF FINANCIAL STATEMENT PRESENTATION  --  The accompanying consolidated 
financial statements include the accounts of Alliance Imaging, Inc. and its 
consolidated subsidiaries.  Significant intercompany transactions have been 
eliminated.  The Company has an interest in a partnership whose operations 
are similar to the Company's.  A subsidiary of the Company owns 49% of this 
partnership as a general and limited partner; this partnership is accounted 
for under the equity method.

USE OF ESTIMATES  --  The preparation of financial statements in conformity 
with generally accepted accounting principles requires management to make 
estimates and assumptions that affect the amounts reported in the financial 
statements and accompanying notes.  Actual results could differ from those 
estimates.

DEBT RESTRUCTURING  --  Effective December 31, 1994, the Company 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, the Company recorded 
special charges totaling $13,339,000 related to an equipment exchange 
transaction, the impairment of certain equipment, debt restructuring and 
employee severances.  The Company 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.  The Company 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.  The Company 
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, the Company 
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  --  The Company considers short-term 
investments with original maturities of three months or less to be cash 
equivalents.

ACCOUNTS RECEIVABLE  --  The Company provides shared and single-user 
diagnostic imaging equipment and technical support services to the health 
care industry and directly to patients on an outpatient basis.  Substantially 
all of the Company's accounts receivable are due from hospitals, other health 
care providers and health insurance providers located throughout the United 
States.  Services are generally provided pursuant to long-term contracts 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.

                                       20
<PAGE>

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 the Company continues to operate the 
equipment beyond its initial estimated life, the residual value is then 
depreciated to a nominal salvage value over three years.

Routine maintenance and repairs are charged to expense as incurred.  Major 
repairs and purchased software and hardware upgrades, which extend the life 
or add value to the equipment, are capitalized and depreciated over the 
remaining useful life.

With the exception of a small amount of office furniture and equipment, 
substantially all of the property owned by the Company relates to diagnostic 
imaging equipment, tractors and trailers used in the business.

GOODWILL  -- The Company amortizes goodwill 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 issued Statement of Financial Accounting 
Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and 
for Long-Lived Assets to be Disposed Of" (SFAS No. 121), in March 1995.  SFAS 
No. 121 requires long-lived assets and certain intangibles held and used by 
the Company 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.  The Company adopted SFAS No. 121 in the first quarter of 
1996 with no material effect on the Company's financial statements.

REVENUE RECOGNITION  --  The majority of the Company's revenues are derived 
directly from health care providers.  To a lesser extent, revenues are 
generated from direct billings to patients or their medical 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 8%, 10% and 13% of revenues 
in the years ended December 31, 1996, 1995 and 1994, 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  --  The Company calculates deferred taxes and related income 
tax expense using the liability method.  This method determines deferred 
taxes by applying the current tax rate to the cumulative temporary 
differences between recorded carrying amounts and the corresponding tax basis 
of assets and liabilities.  A valuation allowance is established for deferred 
tax assets unless their realization is considered more likely than not.  The 
Company's provision for income taxes is the sum of the change in the balance 
of deferred taxes between the beginning and the end of the period plus income 
taxes currently payable.

INVESTMENT TAX CREDITS  --  The Company accounts for investment tax credits 
under the flow through method.

FAIR VALUES OF FINANCIAL INSTRUMENTS  --  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 the Company.

The following methods and assumptions were used by the Company in estimating 
its fair value disclosures for financial instruments:

CASH AND SHORT-TERM INVESTMENTS:  The carrying amount reported in the balance 
sheet for cash and cash equivalents approximates its fair value.

LONG-TERM DEBT:  The fair values of the Company's long-term debt are 
estimated using discounted cash flow analyses, based on the Company's current 
incremental rates for similar types of borrowing arrangements.

                                       21

    The carrying amounts and estimated fair values of the Company's financial 
instruments are as follows:

Redeemable preferred stock              4,694,000      2,788,000     16,430,000     (See Below)

</TABLE>

As more fully discussed in Note 4, the Company has repurchased all of its 
redeemable preferred stock.  The Company 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 the Company'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, the 
Company believes the $16,430,000 carrying amount at December 31, 1995, which 
represents the original fair value of the preferred stock increased for the 
1995 cumulative dividend, reasonably approximates its fair value at that date.

EARNINGS PER COMMON SHARE  --  Earnings per common share have been computed 
based on the weighted average number of shares outstanding during each year 
and 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 the Company's common stock.

    The net change in the Company'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, the 
Company 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,  the 
Company has approximately $6,700,000 of operating loss carryovers available 
in 1997 for federal regular income tax purposes.  Future changes in the 
ownership of the Company could result in additional limitations on the 
utilization of its operating loss carryovers.

    A reconciliation of the expected total provision for income taxes, 
computed using the federal statutory rate on income before extraordinary 
gains, is as follows:

</TABLE>

    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, the Company entered into a Bridge Loan Agreement 
(enabling the Company 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, the 
Company 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, the Company 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, the Company 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, the Company 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).  The effects of  
the conversion of the senior bridge loan into Series D convertible preferred 
stock and the January 2, 1997 senior bridge loan and related securities 
repurchase transactions, are presented on a pro forma basis as of December 
31, 1996 in the accompanying pro forma consolidated balance sheet.  
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 the 
Company's 1996 historical results of operations.

    In November 1996, the Company arranged for the sale of all of its  senior 
notes by the original holders to new owners.  In connection with the sale, 
the Company 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 the Company 
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, the Company may make 
voluntary monthly principal and interest payments of $335,000 through October 
2002 to fully retire the notes.  The Company 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 the Company's senior notes, and 
excluding the senior bridge loan, which was converted to preferred stock in 
March 1997, and the debentures refinanced thereby):

    Year ending December 31:
        1997                               $16,323,000
        1998                                17,263,000
        1999                                14,914,000

    Of the Company's total indebtedness at December 31, 1996, $83,552,000 is 
an obligation of the Company and $5,473,000 is an obligation of the Company's 
consolidated subsidiaries.

    The Company has a $3 million revolving line of credit with a bank.  The 
line bears interest at the bank's prime rate (8.25% at December 31, 1996 and 
8.5% at December 31, 1995) plus two percent, with a commitment fee of 0.375% 
per year on the unused balance, and is secured by substantially all of the 
Company's accounts receivable.  The line of credit had not been utilized 
through December 31, 1996.

5.  PREFERRED AND COMMON STOCK

PREFERRED STOCK  --  The Company 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 the Company's debt refinancing effective December 31, 
1996 (SEE NOTE 4), the Company 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 the Company 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 the Company after 
December 31, 2006.

    In connection with the Royal acquisition (NOTE 8), the Company 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 
the Company's option. Holders of Series C convertible preferred stock may 
convert their stock into common stock at a price of $5 per common share.

    In the event of liquidation, dissolution or winding up of the Company, 
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.

                                       25
<PAGE>

    The holders of shares of preferred stock are not entitled to any voting 
rights with respect to any matters voted upon by the common stockholders. 
However, a majority of preferred stockholders (with each series voting as a 
single class) must approve certain corporate transactions including the 
authorization of additional classes or series of stock ranking prior to their 
stock, any increase in the number of authorized shares of their preferred 
stock series, any amendment to the terms of such preferred stock series and 
similar actions.

STOCK OPTIONS AND AWARDS  --  The Company has elected to follow Accounting 
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" 
(APB 25) and related Interpretations in accounting for its employee stock 
options because, as discussed below, the alternative fair value accounting 
provided for under FASB Statement No. 123, "Accounting for Stock-Based 
Compensation," requires use of option valuation models that were not 
developed for use in valuing employee stock options.  Under APB 25, because 
the exercise price of the Company's employee stock options equals the market 
price of the underlying stock on the date of grant, no compensation expense 
is recognized.

    The Company's 1991 Stock Option Plan provides that up to 2,000,000 shares 
may be granted to management and key employees.  Options are granted at their 
fair market value at the date of grant. All options granted have 10 year 
terms and vest and become fully exercisable at the end of 3 to 4 years of 
continued employment.  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 the Company has accounted for its employee stock options 
granted subsequent to December 31, 1994 under the fair value method of that 
Statement.  The fair value for these options was estimated as of the date of 
grant using 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 the 
Company's common stock of .43; and a weighted-average expected life of the 
option of 7 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 the Company's employee stock 
options have characteristics significantly different from those of traded 
options, and because changes in the subjective input assumptions can 
materially affect the fair value estimate, in management's opinion, the 
existing models do not necessarily provide a reliable single measure of the 
fair value of its employee stock options.

    For purposes of pro forma disclosures, the estimated fair value of the 
options is amortized to expense over the options' maximum vesting period.  
The Company's pro forma information for the year ended December 31, 1996 
follows:

         Pro forma net income                             $12,577,000
         Pro forma earnings per share                           $1.17

    At December 31, 1996 the Company had 328,900 warrants outstanding to 
purchase common stock with exercise prices ranging from $2.50 to $5.00 per 
share over terms of three to ten years.  The weighted-average grant-date fair 
value of the warrants was $2.13.

6.  COMMITMENTS

The Company 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 the Company under certain circumstances.  Contract payments are 
approximately $9,200,000 per year.  At December 31, 1996, the Company had 
binding equipment purchase commitments totaling approximately $29,200,000.

    The Company 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:

    Year ending December 31:
                   1997                $1,478,000

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

    The Company's total rental expense, which includes short-term equipment 
rentals, for the years ended December 31, 1996, 1995 and 1994 was $3,380,000, 
$1,923,000 and $2,781,000, respectively.

7.  401(K)  SAVINGS  PLAN

The Company established a 401(k) Savings Plan in January 1990.  All employees 
of the Company are eligible to participate after a six month waiting period. 
Employees may contribute between 1% and 15% of their annual compensation.  
The Company 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.  The Company may also make discretionary contributions 
depending on profitability.  The Company incurred and charged to expense 
$157,000, $140,000 and $119,000 during 1996, 1995 and 1994, respectively, 
related to the plan.

8.  ACQUISITION

    On April 26, 1996, the Company acquired all of the outstanding shares of 
Royal Medical Health Services, Inc. (Royal) of Pittsburgh, Pennsylvania.  
Like the Company, Royal is a provider of comprehensive MRI services.  The 
Company issued 3,876 shares of Series C convertible preferred stock valued at 
$388,000, 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 the 
Company's consolidated financial statements from the date of acquisition.

    The unaudited pro forma information below presents combined results of 
operations as if the Royal acquisition had occurred at the beginning of the 
respective periods presented.  The unaudited pro forma information is not 
necessarily indicative of the results of operations of the combined company 
had the acquisition actually occurred at the beginning of the periods 
presented, nor is it necessarily indicative of future results.

                            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, 1996 and 1995 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.  Our audits also included the 
financial statement schedules listed in the Index at Item 14(a).  These 
financial statements and schedules are the responsibility of the Company'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, 1996 and 1995, 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.  Also, in our opinion, the related financial statement 
schedules, when considered in relation to the basic financial statements taken 
as a whole, present fairly in all material respects the information set forth 
therein.

be managed by or under the direction of the Board of Directors.  In addition 
to the powers and authority expressly conferred upon them by the DGCL or by 
this Certificate of Incorporation or the Bylaws of this corporation, the 
directors are hereby empowered to exercise all such powers and do all such 
acts and things as may be exercised or done by this corporation.

                      B.   The Board of Directors may adopt, amend or repeal 
the Bylaws of this corporation.

                      C.   Election of directors need not be by written 
ballot.

                 SIX: The officers of this corporation shall be chosen in

                                                                        Page 3

                 SEVEN:    No director of this corporation shall be 
personally liable to this corporation or its stockholders for monetary 
damages for any breach of fiduciary duty by such a director as a director.  
Notwithstanding the foregoing sentence, a director shall be liable to the 
extent provided by applicable law (i) for any breach of the director's duty 
of loyalty to this corporation or its stockholders, (ii) for acts or 
omissions not in good faith or which involve intentional misconduct or a 
knowing violation of law, (iii) pursuant to Section 174 of the DGCL or (iv) 
for any transaction from which such director derived an improper personal 
benefit.  This Article SEVEN is also contained in Article V, Section 5.1 of 
this corporation's Bylaws.  No amendment to or repeal of this Article SEVEN 
shall apply to or have any effect on the liability or alleged liability of 
any director of this corporation for or with respect to any acts or omissions 
of such director occurring prior to such amendment or repeal.  If the DGCL is 
amended hereafter to further eliminate or limit the personal liability of 
directors, the liability of a director of this corporation shall be limited 
or eliminated to the fullest extent permitted by the DGCL, as amended.

                 EIGHT:    A.   RIGHT TO INDEMNIFICATION.  Each person who 
was or is made a party to or is threatened to be made a party to or is 
involuntarily involved in any action, suit or proceeding, whether civil, 
criminal, administrative or investigative (a "Proceeding"), by reason of the 
fact that he or she is or was a director or officer of this corporation, or 
is or was serving (during his or her tenure as director and/or officer) at 
the request of this corporation as a director, officer, employee or agent of 
another corporation or of a partnership, joint venture, trust or other 
enterprise, whether the basis of such Proceeding is an alleged action or 
inaction in an official capacity as a director or officer or in any other 
capacity while serving as a director or officer, shall be indemnified and 
held harmless by this corporation to the fullest extent authorized by the 
DGCL (or other applicable law), as the same exists or may hereafter be 
amended, against all expense, liability and loss (including attorneys' fees, 
judgments, fines, ERISA excise taxes or penalties and amounts paid or to be 
paid in settlement) reasonably incurred or suffered by such person in 
connection with such Proceeding.  Such director or officer shall have the 
right to be paid by this corporation for expenses incurred in defending any 
such Proceeding in advance of its final disposition; provided, however, that, 
if the DGCL (or other applicable law) requires, the payment of such expenses 
in advance of the final disposition of any such Proceeding shall be made only 
upon receipt by this corporation of an undertaking by or on behalf of such 
director or officer to repay all amounts so advanced if it should be 
determined ultimately that he or she is not entitled to be indemnified under 
this Article EIGHT or otherwise.

                      B.   RIGHT OF CLAIMANT TO BRING SUIT.  If a claim under 
paragraph A of this Article EIGHT is not paid in full by this corporation 
within ninety (90) days after a written claim has been received by this 
corporation, the claimant may at any time thereafter bring suit against this 
corporation to recover the unpaid amount of the claim, together with interest 
thereon, and, if successful in whole or in part, the claimant shall also be 
entitled to be paid the expense of prosecuting such claim, including 
reasonable attorneys' fees incurred in connection therewith.  It shall be a 
defense to any such action (other than an action brought to enforce a claim 
for 

<PAGE>

                                                                        Page 4

expenses incurred in defending any Proceeding in advance of its final 
disposition where the required undertaking, if any is required, has been 
tendered to this corporation) that the claimant has not met the standards of 
conduct which make it permissible under the DGCL (or other applicable law) 
for this corporation to indemnify the claimant for the amount claimed, but 
the burden of proving such defense shall be on this corporation.  Neither the 
failure of this corporation (or of its full Board of Directors, its directors 
who are not parties to the Proceeding with respect to which indemnification 
is claimed, its stockholders, or independent legal counsel) to have made a 
determination prior to the commencement of such action that indemnification 
of the claimant is proper in the circumstances because he or she has met the 
applicable standard of conduct set forth in the DGCL (or other applicable 
law), nor an actual determination by any such person or persons that such 
claimant has not met such applicable standard of conduct, shall be a defense 
to such action or create a presumption that the claimant has not met the 
applicable standard of conduct.

                      C.   NON-EXCLUSIVITY OF RIGHTS.  The rights conferred 
by this Article EIGHT shall not be exclusive of any other right which any 
director, officer, representative, employee or other agent may have or 
hereafter acquire under the DGCL or any other statute, or any provision 
contained in this corporation's Certificate of Incorporation or Bylaws, or 
any agreement, or pursuant to a vote of stockholders or disinterested 
directors, or otherwise.

                      D.   INSURANCE AND TRUST FUND.  In furtherance and not in
limitation of the powers conferred by statute:

                           (1)  this corporation may purchase and maintain 
insurance on behalf of any person who is or was a director, officer, employee 
or agent of this corporation, or is serving at the request of this 
corporation as a director, officer, employee or agent of another corporation, 
partnership, joint venture, trust or other enterprise, against any liability 
asserted against him and incurred by him in any such capacity, or arising out 
of his status as such, whether or not this corporation would have the power 
to indemnify him against such liability under the provisions of law; and

                           (2)  this corporation may create a trust fund, 
grant a security interest and/or use other means (including, without 
limitation, letters of credit, surety bonds and/or other similar 
arrangements), as well as enter into contracts providing indemnification to 
the fullest extent permitted by law and including as part thereof provisions 
with respect to any or all of the foregoing, to ensure the payment of such 
amount as may become necessary to effect indemnification as provided therein, 
or elsewhere.

                      E.   INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THIS 
CORPORATION.  This corporation may, to the extent authorized from time to 
time by the Board of Directors, grant rights to indemnification, including 
the right to be paid by this corporation the expenses incurred in defending 
any Proceeding in advance of its


<PAGE>

                                                                        Page 5

final disposition, to any employee or agent of this corporation to the 
fullest extent of the provisions of this Section or otherwise with respect to 
the indemnification and advancement of expenses of directors and officers of 
this corporation.

                      F.   AMENDMENT.   This Article EIGHT is also contained 
in Article V, Sections 5.2 through 5.7 of this corporation's Bylaws.  Any 
repeal or modification of this Article EIGHT shall not change the rights of 
an officer or director to indemnification with respect to any action or 
omission occurring prior to such repeal or modification.

                 NINE:     This corporation reserves the right to alter, 
amend, rescind or repeal any provision contained in this Certificate of 
Incorporation, in the manner now or hereafter prescribed by statute, and all 
rights conferred on stockholders herein are granted subject to this 
reservation.

Trigger Date                                                        3%
- -------------------------------------------------------------------------------
     Fourth full calendar month after Special 
Dividend Event Trigger Date and all time periods

     than all) of the outstanding shares of Series D Preferred Stock owned by 
     each holder at a purchase price per share equal to the Face Amount per

     Trigger Date to each holder either electing to repurchase such holder's 
     shares pursuant to the provisions of this Section 4(b)(3) or declining 
     to so elect (the "Special Dividend Event Repurchase Offer").  

<PAGE>

                                                                        Page 8

            (4)  Within 10 days after receipt of a Special Dividend Event 
     Repurchase Offer, each holder shall send a written notice to the Company 
     either accepting or rejecting such Special Dividend Event Repurchase 
     Offer.  The Company shall purchase all of the shares of each holder 
     accepting the Special Dividend Event Repurchase Offer within 10 days 
     after receipt of the notice from the holder referred to in the previous 
     sentence at a purchase price per share equal to the Face Amount per 
     share plus Accumulated Dividends.  

            (5)  With respect to the shares held by any holder of shares of 
     Series D Preferred Stock that does not accept a Special Dividend 
     Repurchase Offer, Special Dividends with respect to such shares shall 
     cease to accrue as of the first day of the first calendar month 
     following the date of the Special Dividend Event Repurchase Offer 
     (subject to Section 4(b)(6) below).  Any holder of shares of Series D 
     Preferred Stock that does not timely send a written notice to the 
     Company either accepting or rejecting a Special Dividend Event 
     Repurchase Offer shall be deemed to have rejected such offer.  

            (6)  Notwithstanding any holder's rejection or deemed rejection 
     of a Special Dividend Repurchase Offer, upon any later Special Dividend 
     Event Trigger Date Special Dividends on the shares of Series D Preferred 
     Stock owned by such holder shall accrue as set forth in Section 4(b)(2) 
     above.

         c.   TIME OF PAYMENT.  

            (1)  Regular Dividends shall be cumulative from the Issue Date 
     and shall be payable in arrears, when and as declared by the Board, on 
     March 31, June 30, September 30, and December 31 of each year (each such 
     date being herein referred to as a "Dividend Payment Date"), commencing 
     on June 30, 1997.  The quarterly period between consecutive Dividend 
     Payment Dates shall hereinafter be referred to as a "Dividend Period."  
     Each such Regular Dividend shall be paid to the holders of record of the 
     Series D Preferred Stock as their names appear on the share register of 
     the Company on the corresponding Record Date.  As used above, the term 
     "Record Date" means, with respect to the Regular Dividend payable on 
     March 31, June 30, September 30 and December 31, respectively, of each 
     year, the preceding March 15, June 15, September 15 and December 15, or 
     such other record date designated by the Board of the Company with 
     respect to the Regular Dividend payable on such respective Dividend 
     Payment Date.  Regular Dividends on account of arrears for any past 
     Dividend Periods may be declared and paid at any time, without reference 
     to any Dividend Payment Date, to holders of record on such date, not 
     exceeding 50 days preceding the payment date thereof, as may be fixed by 
     the Board.

            (2)  Special Dividends shall be cumulative from the date of the 
     first day of the first full calendar month after any Special Dividend 
     Event Trigger Date and shall be payable in arrears, when and as declared 
     by the Board, on each Dividend Payment Date.  Each such Special Dividend 
     shall be paid to the holders of record of the Series D Preferred Stock 
     as their names appear on the share register of the Company on the 
     corresponding Record Date.  Special Dividends on account of arrears for 
     any past Dividend Periods may be declared and paid at any time, without 
     reference to any Dividend Payment Date, to holders of record on such 
     date, not exceeding 50 days preceding the payment date thereof, as may 
     be fixed by the Board.

         d.   ACCUMULATION.  In the event that full cash Regular Dividends 
(and any full cash Special Dividends) are not paid to the holders of all 
outstanding shares of Series D Preferred Stock, and funds available shall be 
insufficient to permit payment in full in cash to all such holders of the 
preferential amounts to which they are they entitled, the entire amount 
available for payment of cash dividends shall be distributed among the 
holders of the Series D Preferred Stock ratably in proportion to the full 
amount to which they would otherwise be respectively entitled, and any 
remainder not paid in cash to the holders of the Series D Preferred Stock 
shall cumulate as provided in this subsection 4(d). If, on any Dividend 
Payment Date, the holders of the Series D Preferred Stock shall not have 
received the full Regular Dividends and full Special Dividends provided for 
in this Section 4, then such dividends shall cumulate, whether or not earned 
or declared, with additional dividends thereon to accrue at the rate of eight 

<PAGE>

                                                                        Page 9

percent (8%) per annum for each succeeding full Dividend Period during which 
such dividends shall remain unpaid.  Unpaid dividends for any period less 
than a full Dividend Period shall cumulate on a day-to-day basis and shall be 
computed on the basis of a 360 day year.  "Accumulated Dividends" shall mean, 
as of any date, all Regular Dividends and Special Dividends that are either 
undeclared or unpaid as of such date.

         e.   RESTRICTIONS WITH RESPECT TO JUNIOR SECURITIES.  

            (1)  So long as any Series D Preferred Stock shall remain 
     outstanding, no regular periodic cash dividend whatsoever shall be 
     declared or paid upon or set apart for payment on any class of Junior 
     Securities, unless in each instance at such time no Accumulated 
     Dividends, Change in Control Dividend A or Change in Control Dividend B 
     shall be accrued but unpaid.  

            (2)  So long as any Series D Preferred Stock shall remain 
     outstanding, no shares of Junior Securities shall be redeemed or 
     purchased for cash by the Company or any parent or subsidiary thereof 
     nor shall any moneys be paid to or made available for a sinking fund for 
     redemption or purchase of any shares of Junior Securities.

            (3)  The restrictions set forth in Sections 4(e)(1) and 4(e)(2) 
     above shall not apply to (i) up to $100,000 per calendar year applied to 
     redemption or purchase by the Company of Junior Securities owned by 
     employees of the Company in connection with the separation of such 
     employees from their employment with the Company, or (ii) any particular 
     cash dividend, redemption or purchase if the holders of a majority of 
     then outstanding shares of Series D Preferred Stock consent in writing 
     to the declaration or payment of such cash dividend, redemption or 
     purchase, as the case may be.

    5.   LIQUIDATION PREFERENCE.

         a.   GENERAL.  Upon a Liquidation Event, the holders of Series D 
Preferred Stock then outstanding shall be entitled to be paid, out of the 
assets of the Company available for distribution to its shareholders, whether 
from capital, surplus or earnings ("Available Assets"), before any payment 
shall be made in respect of any Junior Security, an amount equal to the Face 
Amount per share PLUS an amount equal to all Accumulated Dividends, if any 
(in the aggregate, the "Liquidation Preference Amount").  If upon a 
Liquidation Event, the Available Assets shall be insufficient to pay the 
holders of the Series D Preferred Stock the full Liquidation Preference 
Amount, the holders of the Series D Preferred Stock shall share ratably in 
any distribution of assets according to the respective amounts which would be 
payable in respect of the shares held by them upon such distribution if all 
amounts payable on or with respect to said shares were paid in full.  

         b.   NOTICE REQUIRED.  Written notice of any voluntary or 
involuntary Liquidation Event, stating the payment date and the place where 
the distributable amount shall be payable, shall be given by mail, postage 
prepaid, not less than thirty (30) days prior to the payment date stated 
therein, to the holders of record of the Series D Preferred Stock at their 
respective addresses as the same shall then appear on the books of the 
Company.  

    6.   CONVERSION. 

         a.   EXERCISE OF CONVERSION RIGHT.  Each holder of Series D 
Preferred Stock shall have the right, at its option, at any time from the 
Issue Date through December 31, 2006, to convert, subject to the terms and 
provisions of this Section 6, all or any portion of its Series D Preferred 
Stock then outstanding into such number of fully paid and non-assessable 
shares of Common Stock as results from dividing (i) the sum of (A) the Face 
Amount of all shares of Series D Preferred Stock to be converted plus (B) any 
Accumulated Dividends on such shares, by (ii) the applicable Conversion Price 

<PAGE>

                                                                        Page 10


(as defined below) on the Conversion Date (as defined below).   Such 
conversion shall be deemed to have been made at the close of business on the 
date that the certificate or certificates for shares of Series D Preferred 
Stock shall have been surrendered for conversion and written notice shall 
have been received as provided in Section 6(b) (the "Conversion Date"), so 
that the person or persons entitled to receive the shares of Common Stock 
upon conversion of such shares of Series D Preferred Stock shall be treated 
for all purposes as having become the record holder or holders of such shares 
of Common Stock at such time and such conversion shall be at the Conversion 
Price in effect at such time.  Upon conversion of any shares of Series D 
Preferred Stock pursuant to this Section 6, the rights of the holder of such 
shares upon the Conversion Date shall be the rights of a holder of Common 
Stock only, and each such holder shall not have any rights in its former 
capacity as a holder of shares of Series D Preferred Stock. 

         b.   NOTICE TO COMPANY.  In order to convert all or any portion of 
its outstanding Series D Preferred Stock into shares of Common Stock, the 
holder of such Series D Preferred Stock shall deliver the shares of Series D 
Preferred Stock to be converted to the Company at its principal office, 
together with written notice that it elects to convert those shares of Series 
D Preferred Stock into shares of Common Stock in accordance with the 
provisions of this Section 6.  Such notice shall specify the number of shares 
of Series D Preferred Stock to be converted and the name or names in which 
the holder wishes the certificates for shares of Common Stock to be 
registered, together with the address or addresses of the person or persons 
so named, and, if so required by the Company, shall be accompanied by a 
written instrument or instruments of transfer in form satisfactory to the 
Company, duly executed by the registered holder of the shares of Series D 
Preferred Stock to be converted or by its attorney duly authorized in writing.

         c.   DELIVERY OF CERTIFICATE.  As promptly as practicable after the 
surrender as hereinabove provided of shares of Series D Preferred Stock for 
conversion into shares of Common Stock, the Company shall deliver or cause to 
be delivered to the holder, or the holder's designees, certificates 
representing the number of fully paid and non-assessable shares of Common 
Stock into which the shares of Series D Preferred Stock are entitled to be 
converted, together with a cash adjustment in respect of any fraction of a 
share to which the holder shall be entitled as provided in Section 6(d), and, 
if less than the entire number of shares of Series D Preferred Stock 
represented by the certificate or certificates surrendered is to be 
converted, a new certificate for the number of shares of Series D Preferred 
Stock not so converted.  So long as any shares of Series D Preferred Stock 
remain outstanding, the Company shall not close its Common Stock transfer 
books.  The issuance of certificates for shares of Common Stock upon the 
conversion of shares of Series D Preferred Stock shall be made without charge 
to the holder for any tax in respect of the issuance of such certificates 
(other than any transfer, withholding or other tax if the shares of Common 
Stock are to be registered in a name different from that of the registered 
holder of Series D Preferred Stock).

         d.   FRACTIONAL SHARES.  No fractional shares of Common Stock or 
scrip representing fractional shares of Common Stock shall be issued upon any 
conversion of any shares of Series D Preferred Stock, but, in lieu thereof, 
there shall be paid an amount in cash equal to the same fraction of the 
Market Price of a whole share of Common Stock as of the Conversion Date. 

<PAGE>

                                                                        Page 11

         e.   RESERVATION OF SHARES.  The Company shall at all times reserve 
and keep available out of its authorized but unissued shares of Common Stock, 
solely for the purpose of effecting the conversion of shares of Series D 
Preferred Stock, the full number of whole shares of Common Stock then 
deliverable upon the conversion of all shares of Series D Preferred Stock 
then outstanding.  The Company shall take at all times such corporate action 
as shall be necessary in order that the Company may validly and legally issue 
fully paid and non-assessable shares of Common Stock upon the conversion of 
shares of Series D Preferred Stock in accordance with the provisions of this 
Section 6.

         f.   REGISTRATION.  If any shares of Common Stock to be reserved for 
the purpose of conversion of Series D Preferred Stock require registration or 
listing with, or approval of, any governmental authority, stock exchange or 
other regulatory body under any federal or state law or regulation or 
otherwise, before such shares may be validly issued or delivered upon 
conversion, the Company shall, in good faith and as expeditiously as 
possible, endeavor to secure such registration, listing or approval, as the 
case may be.

         g.   SHARES VALIDLY ISSUED AND NON-ASSESSABLE.  All shares of Common 
Stock that may be issued upon conversion of the Series D Preferred Stock 
shall upon issuance by the Company be validly issued, fully paid and 
nonassessable and free from all taxes, liens and charges with respect to the 
issuance thereof.

         h.   RETIREMENT OF SHARES.  Any shares of Series D Preferred Stock 
converted pursuant to the provisions of this Section 6 shall be retired and 
given the status of authorized and unissued Preferred Stock, undesignated as 
to series, subject to reissuance by the Company as shares of Preferred Stock 
of one or more series, as may be determined from time to time by the Board.

    7.   CONVERSION PRICE.  As used herein, the "Conversion Price" shall 
initially be $6.00 per share of Common Stock, subject to adjustment as set 
forth below.  No payment or adjustment shall be made for any dividends on the 
Common Stock issuable in such conversion.  The Conversion Price shall be 
subject to adjustment from time to time as follows: 

         a.   COMMON STOCK ISSUED AT LESS THAN THE CONVERSION PRICE.  If the 
Company shall issue any Common Stock other than Excluded Stock (as 
hereinafter defined) without consideration or for a consideration per share 
less than the Conversion Price in effect immediately prior to such issuance, 
the Conversion Price in effect immediately prior to each such issuance shall 
immediately be reduced to the price determined by dividing (i) an amount 
equal to the sum of (A) the number of shares of Common Stock outstanding 
immediately prior to such issuance multiplied by the Conversion Price in 
effect immediately prior to such issuance and (B) the consideration, if any, 
received by the Company upon such issuance, by (ii) the total number of 
shares of Common Stock outstanding immediately after such issuance.  For the 
purposes of any adjustment of the Conversion Price pursuant to this Section 
7(a), the following provisions shall be applicable:

             (1)  CASH.  In the case of the issuance of Common Stock for 
     cash, the amount of the consideration received by the Company shall be 
     deemed to be the amount of the cash proceeds received by the Company for 
     such Common Stock before deducting therefrom any discounts, commissions, 
     taxes or other expenses allowed, paid or incurred by the Company for any

     underwriting or otherwise in connection with the issuance and sale 
     thereof.

             (2)  CONSIDERATION OTHER THAN CASH.  In the case of the issuance 
     of Common Stock (otherwise than upon the conversion of shares of capital 
     stock or other securities of the Company) for a consideration in whole 
     or in part other than cash, including securities acquired in exchange 
     therefor (other than securities by their terms so exchangeable), the 
     consideration other than cash shall be deemed to be the fair value 
     thereof as determined by the Board; provided that such fair value as 
     determined by the Board shall not exceed the aggregate Market Price of 
     the shares of Common Stock being issued as of the date the Board 
     authorizes the issuance of such shares.

             (3)  OPTIONS AND CONVERTIBLE SECURITIES.  In the case of the 
     issuance of (i) options, warrants or other rights to purchase or acquire 
     Common Stock (whether or not at the time exercisable), (ii) securities 
     by their terms convertible into or exchangeable for Common Stock 
     (whether or not at the time so convertible or exchangeable) or (iii) 
     options, warrants or rights to purchase such convertible or exchangeable 
     securities (whether or not at the time exercisable):

                 (A)  the aggregate maximum number of shares of Common Stock 
          deliverable upon exercise of such options, warrants or other rights 
          to purchase or acquire Common Stock shall be deemed to have been 
          issued at the time such options, warrants or rights were issued and 
          for a consideration equal to the consideration (determined in the 
          manner provided in subsections (1) and (2) above), if any, received 
          by the Company upon the issuance of such options, warrants or 
          rights plus the minimum purchase price provided in such options, 
          warrants or rights for the Common Stock covered thereby;

                 (B)  the aggregate maximum number of shares of Common Stock 
          deliverable upon conversion of or in exchange for any such 
          convertible or exchangeable securities, or upon the exercise of 
          options, warrants or other rights to purchase or acquire such 
          convertible or exchangeable securities and the subsequent 
          conversion or exchange thereof, shall be deemed to have been issued 
          at the time such securities were issued or such options, warrants 
          or rights were issued and for a consideration equal to the 
          consideration, if any, received by the Company for any such 
          securities and related options, warrants or rights (excluding any 
          cash received on account of accrued interest or accrued dividends), 
          plus the additional consideration (determined in the manner 
          provided in subsections (1) and (2) above), if any, to be received 
          by the Company upon the conversion or exchange of such securities, 
          or upon the exercise of any related options, warrants or rights to 
          purchase or acquire such convertible or exchangeable securities and 
          the subsequent conversion or exchange thereof; 

                 (C)  on any change in the number of shares of Common Stock 
          deliverable upon exercise of any such options, 

<PAGE>

                                                                        Page 13


          warrants or rights or conversion or exchange of such convertible or 
          exchangeable securities or any change in the consideration to be 
          received by the Company upon such exercise, conversion or exchange, 
          including, but not limited to, a change resulting from the 
          anti-dilution provisions thereof, the Conversion Price as then in 
          effect shall forthwith be readjusted to such Conversion Price as 
          would have been obtained had an adjustment been made upon the 
          issuance of such options, warrants or rights not exercised prior to 
          such change, or of such convertible or exchangeable securities not 
          converted or exchanged prior to such change, upon the basis of such 
          change;

                 (D)  on the expiration or cancellation of any such options, 
          warrants or rights, or the termination of the right to convert or 
          exchange such convertible or exchangeable securities, if the 
          Conversion Price shall have been adjusted upon the issuance 
          thereof, the Conversion Price shall forthwith be readjusted to such 
          Conversion Price as would have been obtained had an adjustment been 
          made upon the issuance of such options, warrants, rights or such 
          convertible or exchangeable securities on the basis of the issuance 
          of only the number of shares of Common Stock actually issued upon 
          the exercise of such options, warrants or rights, or upon the 
          conversion or exchange of such convertible or exchangeable 
          securities, if any; and

                 (E)  if the Conversion Price shall have been adjusted upon 
          the issuance of any such options, warrants, rights or convertible 
          or exchangeable securities, no further adjustment of the Conversion 
          Price shall be made for the actual issuance of Common Stock upon 
          the exercise, conversion, or exchange thereof;

          provided, however, that no increase in the Conversion Price shall 
be made pursuant to subsections (A) or (B) of this subsection (3).

         b.   EXCLUDED STOCK.  For purposes of Section 7(a), "Excluded Stock" 
shall mean (i) shares of Common Stock issued or reserved for issuance by the 
Company as a stock dividend payable in shares of Common Stock, or upon any 
subdivision or split up of the outstanding shares of Common Stock or Series D 
Preferred Stock, or upon conversion of shares of the Series D Preferred 
Stock, (ii) under options and warrants outstanding on the date hereof, (iii) 
750,000 shares of Common Stock reserved for issuance to key employees and 
directors of the Company pursuant to the Company's employee stock option plan 
in effect as of the date hereof; (iv) shares of Series E Preferred Stock and 
shares of Common Stock issuable upon the conversion thereof, and (v) 77,520 
shares of Common Stock issuable upon the conversion of the shares of Series C 
Convertible Preferred Stock outstanding on the date hereof.

         c.   STOCK DIVIDENDS, SUBDIVISIONS, RECLASSIFICATIONS OR 
COMBINATIONS.  If the Company shall (i) declare a dividend or make a 
distribution on its Common Stock in shares of its Common Stock, (ii) 
subdivide or reclassify the 

<PAGE>

                                                                        Page 14

outstanding shares of Common Stock into a greater number of shares, or (iii) 
combine or reclassify the outstanding Common Stock into a smaller number of 
shares, the Conversion Price in effect at the time of the record date for 
such dividend or distribution or the effective date of such subdivision, 
combination or reclassification shall be proportionately adjusted so that the 
holder of any shares of Series D Preferred Stock surrendered for conversion 
after such date shall be entitled to receive the number of shares of Common 
Stock which he would have owned or been entitled to receive had such shares 
of Series D Preferred Stock been converted immediately prior to such date.  
Successive adjustments in the Conversion Price shall be made whenever any 
event specified above shall occur.

         d.   OTHER DISTRIBUTIONS.  In case the Company shall fix a record 
date for the making of a distribution to all holders of shares of its Common 
Stock (i) of shares of any class other than its Common Stock, (ii) of 
evidence of indebtedness of the Company or any subsidiary of the Company, 
(iii) of assets, or (iv) of rights or warrants, in each such case the 
Conversion Price in effect immediately prior thereto shall be reduced 
immediately thereafter to the price determined by dividing (1) an amount 
equal to the difference resulting from (A) the number of shares of Common 
Stock outstanding on such record date multiplied by the Conversion Price per 
share on such record date, less (B) the fair market value (as determined by 
the Board) of said shares or evidences of indebtedness or assets or rights or 
warrants to be so distributed, by (2) the number of shares of Common Stock 
outstanding on such record date; PROVIDED, HOWEVER, that, so long as there 
are no Accumulated Dividends on the Series D Preferred Stock or the Series E 
Preferred Stock then outstanding for any previous Dividend Payment Date, the 
provisions of this Section 7(d) shall not apply to distributions consisting 
of cash dividends on the shares of Common Stock up to an amount equal to 50% 
of consolidated net income of the Company and its Majority-Owned Subsidiaries 
as of the calendar year immediately preceding the proposed record date for 
such dividend.  Any adjustment provided for by this Section 7(d) shall be 
made successively whenever such a record date is fixed.  

         e.   CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE.  In case of 
any consolidation with or merger of the Company with or into another 
corporation or other entity, or in case of any sale, lease or conveyance to 
another entity of the assets of the Company as an entirety or substantially 
as an entirety, each share of Series D Preferred Stock shall after the date 
of such consolidation, merger, sale, lease or conveyance be convertible into 
the number of shares of stock or other securities or property (including 
cash) to which the Common Stock issuable (at the time of such consolidation, 
merger, sale, lease or conveyance) upon conversion of such share of Series D 
Preferred Stock would have been entitled upon such consolidation, merger, 
sale, lease or conveyance; and in any such case, if necessary, the provisions 
set forth herein with respect to the rights and interests thereafter of the 
holders of the shares of Series D Preferred Stock shall be appropriately 
adjusted so as to be applicable, as nearly as may reasonably be, to any 
shares of stock or other securities or property thereafter deliverable on the 
conversion of the shares of Series D Preferred Stock.  Nothing in this 
Section 7(e) shall be construed in any way to derogate from the right of the 
holders of the Series D Preferred Stock to require the Company to repurchase 
their shares at the Change in Control Repurchase Price upon a Change in 
Control, as set forth in Section 8(c) hereof.

                                                                        Page 15

         f.   NOTICE TO HOLDERS.  In the event the Company shall propose to 
take any action of the type described in subsections (a), (c), (d), and (e) 
of this Section 7, the Company shall give notice to each holder of shares of 
Series D Preferred Stock, which notice shall specify the record date, if any, 
with respect to any such action and the approximate date on which such action 
is to take place.  Such notice shall also set forth such facts with respect 
thereto as shall be reasonably necessary to indicate the effect of such 
action on the Conversion Price and the number, kind or class of shares or 
other securities or property which shall be deliverable upon conversion of 
shares of Series D Preferred Stock.  In the case of any action which would 
require the fixing of a record date, such notice shall be given at least 10 
days prior to the date so fixed, and in the case of all other action, such 
notice shall be given at least 15 days prior to the taking of such proposed 
action.

         g.   STATEMENT REGARDING ADJUSTMENTS.  Upon the occurrence of each 
adjustment or readjustment of the Conversion Price of the Series D Preferred 
Stock pursuant to this Section 7, the Company shall compute such adjustment 
or readjustment in accordance with the terms hereof and prepare and furnish 
to each holder a certificate setting forth such adjustment or readjustment 
and showing in detail the facts upon which such adjustment or readjustment is 
based.  Each such statement shall be signed by the Company's public 
accountants.

         h.   TREASURY STOCK.  For the purposes of this Section 7, the sale 
or other disposition of any Common Stock theretofore held in the Company's 
treasury shall be deemed to be an issuance thereof.

         i.   GOOD FAITH.  The Company shall not, by amendment of its 
Certificate of Incorporation or through any reorganization, transfer of 
assets, consolidation, merger, dissolution, issuance or sale of securities or 
any other voluntary action, avoid or seek to avoid the observance or 
performance of any of the terms to be observed or performed hereunder by the 
Company, but shall at all times in good faith assist in the carrying out of 
all the provisions of this Section 7 and in the taking of all such action as 
may be necessary or appropriate in order to protect the conversion rights of 
the holders of the shares of Series D Preferred Stock shares against 
impairment of any kind.

    8.   VOTING RIGHTS; PROTECTIVE PROVISIONS; CHANGE OF CONTROL; SPECIAL 
REPURCHASE EVENTS.

         a.   GENERAL.  Except as specifically set forth in the DGCL or 
provided in the balance of this Section 8, the holders of shares of Series D 
Preferred Stock shall not be entitled to any voting rights with respect to 
any matters voted upon by stockholders.

         b.   PROTECTIVE PROVISIONS.  So long as any shares of Series D 
Preferred Stock are outstanding, the written consent or the affirmative vote 
at a meeting called for that purpose of the holders of a majority of the 
shares of Series D Preferred Stock then outstanding, voting separately as a 
class, shall be necessary to validate or effectuate any of the following: (i) 
amend, repeal, alter or change any of the rights, preferences or privileges 
of the shares of Series D Preferred Stock; (ii) create (by reclassification 
of an existing class or series, or otherwise) any new class or series of 
shares of the Company's capital stock, except for classes or series of shares 
ranking, with respect to dividend rights and rights on any Liquidation Event, 
junior to the Series D Preferred Stock and the Series E Preferred Stock; 
(iii) issue any shares of the 

<PAGE>

                                                                        Page 16

Company's capital stock, except for classes or series of shares ranking, with 
respect to dividend rights and rights on any Liquidation Event, junior to the 
Series D Preferred Stock and the Series E Preferred Stock; or (iv) take any 
action that materially and adversely affects the legal rights, preferences or 
privileges of the shares of Series D Preferred Stock.  At any time when there 
are any Accumulated Dividends or any Change in Control Special Dividend A 
accrued but unpaid for any reason, the holders of a majority of the shares of 
Series D Preferred Stock then outstanding, voting separately as a class, 
shall be necessary to validate or effectuate (i) any acquisition by the 
Company of all or substantially all of the assets of another Person, (ii) any 
acquisition by the Company of all or substantially all of the equity 
interests in any Person, and (iii) any merger or recapitalization transaction 
to which the Company is a party.

         c.   HOLDER'S ELECTION UPON CHANGE OF CONTROL.  

             (1)  GENERALLY.  In the event of any Change in Control, each 
     holder of shares of Series D Preferred Stock shall have the right, at 
     such holder's election as set forth below, to receive in respect of each 
     share owned by such holder a sum equal to (i) the then applicable Face 
     Value, PLUS (ii) Accumulated Dividends, PLUS (iii) a "Change of Control 
     Special Dividend A" equal to 18% of the then applicable Face Value.  

             (2)  COMPANY'S NOTIFICATION OBLIGATION.  

                 (A)  The Company shall notify each holder of shares of 
          Series D Preferred Stock in writing within 15 days before any 
          Change in Control pursuant to a transaction to which the Company is 
          a party (a "Company Change of Control Transaction") setting forth a 
          description of the nature of the Change in Control and the date at 
          which such Change in Control is anticipated to take place.  

                 (B)  The Company shall notify each holder of shares of 
          Series D Preferred Stock in writing as soon as the Company has 
          Knowledge of any Change of Control pursuant to a transaction that 
          is not a Company Change of Control Transaction (an "Other Change of 
          Control Transaction") setting forth a description of the nature of 
          the Change in Control and the date at which such Change in Control 
          took place or is anticipated to take place.  

                 (C)  The notices described in clauses (A) and (B) above are 
          collectively denominated "Change in Control Notices".

             (3)  HOLDER'S ELECTION.  Within five (5) days after receipt of 
     the Change of Control Notice, each holder shall notify the Company in 
     writing whether or not such holder will require such holder's shares of 
     Series D Preferred Stock to be redeemed by the Company pursuant to this 
     Section.  If a holder does not timely notify the Company in writing 
     pursuant to the previous sentence, such holder will be deemed to have 
     waived its right to require such holder's shares of Series D Preferred 
     Stock to be redeemed by the Company pursuant to this Section; provided, 
     however, that such waiver shall only apply to the Change of Control 
     relating to the relevant Change of Control Notice, and not any 
     subsequent Change of Control or Change of Control Notice.

             (4)  COMPANY CHANGE OF CONTROL.  The Company shall redeem the 
     shares of each holder of Series D Preferred Stock so electing such a 
     redemption in connection with a Company Change of Control Transaction by 

<PAGE>

                                                                        Page 17

     making cash payments to such holder in respect of each share owned by 
     such holder as follows: (i) a sum equal to the then applicable Face 
     Value PLUS Accumulated Dividends on or prior to the date of the Company 
     Change in Control Transaction as a condition precedent to the 
     effectiveness of such Company Change in Control Transaction, and (ii) a 
     sum equal to the Change in Control Special Dividend A as soon as funds 
     are legally available for payment thereof after the date of the Company 
     Change in Control Transaction.  Any Company Change of Control 
     Transaction shall be void and of no force and effect if the payments set 
     forth in clause (i) of this Section 8(c)(4) are not made on or prior to 
     the date of such Company Change in Control Transaction.

             (5)  OTHER CHANGES OF CONTROL.  The Company shall redeem the 
     shares of each holder of Series D Preferred Stock so electing such a 
     redemption in connection with an Other Change of Control Transaction as 
     promptly as practicable after receipt of such holder's notice of such 
     election by making cash payments to such holder in respect of each share 
     owned by such holder as follows: (i) a sum equal to the then applicable 
     Face Value PLUS Accumulated Dividends plus a sum equal to the Change in 
     Control Special Dividend A as soon as funds are legally available for 
     payment thereof after the date of the Other Change in Control 
     Transaction.  

         d.   SPECIAL REPURCHASE EVENTS.

             (1)  REPRESENTATIONS.  The Company represents and warrants to 
     each holder of shares of Series D Preferred Stock as follows:

                   (d)  knowingly and willfully offering, paying, soliciting 
          or receiving any remuneration (including any kickback, bribe or 
          rebate), directly or indirectly, overtly or covertly, in cash or in 
          kind (i) in return for referring, or to induce the referral of, an 
          individual to a Person for the furnishing or arranging for the 
          furnishing of any item or service for which payment may be made in

     of Series E Preferred Stock that does not timely send

     Dividend Event Repurchase Offer shall be deemed to have rejected such
     offer.

              (6)  Notwithstanding any holder's rejection or deemed rejection

          c.  TIME OF PAYMENT.

     and shall be payable in arrears, when and as declared by the Board, on
     March 31, June 30, September 30, and December 31 of each year (each such
     date being herein referred to as a "Dividend Payment Date"), commencing on
     the first such date immediately following the Issue Date.  The quarterly
     period between consecutive Dividend Payment Dates shall hereinafter be
     referred to as a "Dividend Period."  Each such Regular Dividend shall be
     paid to the holders of record of the Series E Preferred Stock as their
     names appear on the share register of the Company on the corresponding
     Record Date.  As used above, the term "Record Date" means, with respect to
     the Regular Dividend payable on March 31, June 30, September 30 and
     December 31, respectively, of each year, the preceding March 15, June 15,
     September 15 and December 15, or such other record date designated by the
     Board of the Company with respect to the Regular Dividend payable on such
     respective Dividend Payment Date.  Dividends on account of arrears for any
     past Dividend Periods may be declared and paid at any time, without
     reference to any Dividend Payment Date, to holders of record on such date,
     not exceeding 50 days preceding the payment date thereof, as may be fixed
     by the Board.

              (2)  Special Dividends shall be cumulative from the date of the
     first day of the first full calendar month after any Special Dividend Event
     Trigger Date and shall be payable in arrears, when and as declared by the
     Board, on each Dividend Payment Date.  Each such Special Dividend shall be
     paid to the holders of record of the Series E Preferred Stock as their
     names appear on the share register of the Company on the corresponding
     Record Date.  Special Dividends on account of arrears for any past Dividend
     Periods may be declared and paid at any time, without reference to any
     Dividend Payment Date, to holders of record on such date, not exceeding 50
     days preceding the payment date thereof, as may be fixed by the Board.

          d.   ACCUMULATION.  In the event that full cash Regular Dividends (and
any full cash Special Dividends) are not paid to the holders of all outstanding
shares of Series E Preferred Stock, and funds available shall be insufficient to
permit payment in full in cash to all such holders of the preferential amounts
to which they are they entitled, the entire amount available for payment of cash
dividends shall be distributed among the holders of the Series E Preferred Stock
ratably in proportion to the full

<PAGE>

                                                                         Page 12

amount to which they would otherwise be respectively entitled, and any 
remainder not paid in cash to the holders of the Series E Preferred Stock 
shall cumulate as provided in this subsection 4(d). If, on any Dividend 
Payment Date, the holders of the Series E Preferred Stock shall not have 
received the full Regular Dividends and full Special Dividends provided for 
in this Section 4, then such dividends shall cumulate, whether or not earned 
or declared, with additional dividends thereon to accrue at the rate of eight 
percent (8%) per annum for each succeeding full Dividend Period during which 
such dividends shall remain unpaid.  Unpaid dividends for any period less 
than a full Dividend Period shall cumulate on a day-to-day basis and shall be 
computed on the basis of a 360 day year.  "Accumulated Dividends" shall mean, 
as of any date, all Regular Dividends and Special Dividends that are either 
undeclared or unpaid as of such date.

          e.  RESTRICTION WITH RESPECT TO JUNIOR SECURITIES. 

              (1)  So long as any Series E Preferred Stock shall remain
     outstanding, no regular periodic cash dividend whatsoever shall be declared
     or paid upon or set apart for payment on any class of Junior Securities,
     unless in each instance at such time no Accumulated Dividends, Change in
     Control Dividend A or Change in Control Dividend B shall be accrued but
     unpaid. 

              (2)  So long as any Series E Preferred Stock shall remain
     outstanding, no shares of Junior Securities shall be redeemed or purchased
     for cash by the Company or any parent or subsidiary thereof nor shall any
     moneys be paid to or made available for a sinking fund for redemption or
     purchase of any shares of Junior Securities.
     
              (3)  The restrictions set forth in Sections 4(e)(1) and 4(e)(2)
     above shall not apply to (i) up to $100,000 per calendar year applied to
     redemption or purchase by the Company of Junior Securities owned by
     employees of the Company in connection with the separation of such
     employees from their employment with the Company, or (ii) any particular
     cash dividend, redemption or purchase if the holders of a majority of then
     outstanding shares of Series E Preferred Stock consent in writing to the
     declaration or payment of such cash dividend, redemption or purchase, as
     the case may be.

     5.   LIQUIDATION PREFERENCE.

          a.  GENERAL.  Upon a Liquidation Event, the holders of Series E 
Preferred Stock then outstanding shall be entitled to be paid, out of the 
assets of the Company available for distribution to its shareholders, whether 
from capital, surplus or earnings ("Available Assets"), before any payment 
shall be made in respect of any Junior Security, an amount equal to the Face 
Amount per share PLUS an amount equal to all Accumulated Dividends, if any 
(in the aggregate, the "Liquidation Preference Amount").  If upon a 
Liquidation Event, the Available Assets shall be insufficient to pay the 
holders of the Series E Preferred Stock the full Liquidation Preference 
Amount, the holders of the Series E Preferred Stock shall share ratably in 
any distribution of assets according to the respective amounts which would be 
payable in respect of the shares

<PAGE>

                                                                         Page 13

held by them upon such distribution if all amounts payable on or with respect 
to said shares were paid in full.  

          b.   NOTICE REQUIRED.  Written notice of any voluntary or 
involuntary Liquidation Event, stating the payment date and the place where 
the distributable amount shall be payable, shall be given by mail, postage 
prepaid, not less than thirty (30) days prior to the payment date stated 
therein, to the holders of record of the Series E Preferred Stock at their 
respective addresses as the same shall then appear on the books of the 
Company.  

     6.   CONVERSION. 

          a.   EXERCISE OF CONVERSION RIGHT.  Each holder of Series E 
Preferred Stock shall have the right, at its option, at any time from the 
Issue Date through December 31, 2006, to convert, subject to the terms and 
provisions of this Section 6, all or any portion of its Series E Preferred 
Stock then outstanding into such number of fully paid and non-assessable 
shares of Common Stock as results from dividing (i) the sum of (A) the Face 
Amount of all shares of Series E Preferred Stock to be converted plus (B) any 
Accumulated Dividends on such shares, by (ii) the applicable Conversion Price 
(as defined below) on the Conversion Date (as defined below).   Such 
conversion shall be deemed to have been made at the close of business on the 
date that the certificate or certificates for shares of Series E Preferred 
Stock shall have been surrendered for conversion and written notice shall 
have been received as provided in Section 6(b) (the "Conversion Date"), so 
that the person or persons entitled to receive the shares of Common Stock 
upon conversion of such shares of Series E Preferred Stock shall be treated 
for all purposes as having become the record holder or holders of such shares 
of Common Stock at such time and such conversion shall be at the Conversion 
Price in effect at such time.  Upon conversion of any shares of Series E 
Preferred Stock pursuant to this Section 6, the rights of the holder of such 
shares upon the Conversion Date shall be the rights of a holder of Common 
Stock only, and each such holder shall not have any rights in its former 
capacity as a holder of shares of Series E Preferred Stock. 

          b.   NOTICE TO COMPANY.  In order to convert all or any portion of 
its outstanding Series E Preferred Stock into shares of Common Stock, the 
holder of such Series E Preferred Stock shall deliver the shares of Series E 
Preferred Stock to be converted to the Company at its principal office, 
together with written notice that it elects to convert those shares of Series 
E Preferred Stock into shares of Common Stock in accordance with the 
provisions of this Section 6.  Such notice shall specify the number of shares 
of Series E Preferred Stock to be converted and the name or names in which 
the holder wishes the certificates for shares of Common Stock to be 
registered, together with the address or addresses of the person or persons 
so named, and, if so required by the Company, shall be accompanied by a 
written instrument or instruments of transfer in form satisfactory to the 
Company, duly executed by the registered holder of the shares of Series E 
Preferred Stock to be converted or by its attorney duly authorized in writing.

<PAGE>

                                                                         Page 14

          c.   DELIVERY OF CERTIFICATE.  As promptly as practicable after the 
surrender as hereinabove provided of shares of Series E Preferred Stock for 
conversion into shares of Common Stock, the Company shall deliver or cause to 
be delivered to the holder, or the holder's designees, certificates 
representing the number of fully paid and non-assessable shares of Common 
Stock into which the shares of Series E Preferred Stock are entitled to be 
converted, together with a cash adjustment in respect of any fraction of a 
share to which the holder shall be entitled as provided in Section 6(d), and, 
if less than the entire number of shares of Series E Preferred Stock 
represented by the certificate or certificates surrendered is to be 
converted, a new certificate for the number of shares of Series E Preferred 
Stock not so converted.  So long as any shares of Series E Preferred Stock 
remain outstanding, the Company shall not close its Common Stock transfer 
books.  The issuance of certificates for shares of Common Stock upon the 
conversion of shares of Series E Preferred Stock shall be made without charge 
to the holder for any tax in respect of the issuance of such certificates 
(other than any transfer, withholding or other tax if the shares of Common 
Stock are to be registered in a name different from that of the registered 
holder of Series E Preferred Stock).

          d.   FRACTIONAL SHARES.  No fractional shares of Common Stock or 
scrip representing fractional shares of Common Stock shall be issued upon any 
conversion of any shares of Series E Preferred Stock, but, in lieu thereof, 
there shall be paid an amount in cash equal to the same fraction of the 
Market Price of a whole share of Common Stock as of the Conversion Date. 

          e.   RESERVATION OF SHARES.  The Company shall at all times reserve 
and keep available out of its authorized but unissued shares of Common Stock, 
solely for the purpose of effecting the conversion of shares of Series E 
Preferred Stock, the full number of whole shares of Common Stock then 
deliverable upon the conversion of all shares of Series E Preferred Stock 
then outstanding.  The Company shall take at all times such corporate action 
as shall be necessary in order that the Company may validly and legally issue 
fully paid and non-assessable shares of Common Stock upon the conversion of 
shares of Series E Preferred Stock in accordance with the provisions of this 
Section 6.

          f.   REGISTRATION.  If any shares of Common Stock to be reserved 
for the purpose of conversion of Series E Preferred Stock require 
registration or listing with, or approval of, any governmental authority, 
stock exchange or other regulatory body under any federal or state law or 
regulation or otherwise, before such shares may be validly issued or 
delivered upon conversion, the Company shall, in good faith and as 
expeditiously as possible, endeavor to secure such registration, listing or 
approval, as the case may be.

          g.   SHARES VALIDLY ISSUED AND NON-ASSESSABLE.  All shares of 
Common Stock that may be issued upon conversion of the Series E Preferred 
Stock shall upon issuance by the Company be validly issued, fully paid and 
nonassessable and free from all taxes, liens and charges with respect to the 
issuance thereof.

          h.   RETIREMENT OF SHARES.  Any shares of Series E Preferred Stock 
converted pursuant to the provisions of this Section 6 shall be retired and 
given the status of authorized and unissued Preferred Stock, undesignated as 
to series, subject to reissuance by the Company as shares of Preferred Stock 
of one or more series, as may be determined from time to time by the Board.

     7.   CONVERSION PRICE.  As used herein, the "Conversion Price" shall 
initially be the greater of (i) the Average Market Price as of the Issue Date 
and (ii) the Base Conversion Price, subject to adjustment as set forth below. 
The "Base Conversion Price" shall be $6.00 per share of Common Stock (as such 
Common Stock is constituted as of the date of this Certificate, such amount 
to be proportionately adjusted in the event of any stock dividend, stock 
split, subdivision, reclassification, combination or similar event with 
respect to the Common Stock).  No payment or adjustment shall be made for any 
dividends on the Common Stock issuable in such conversion.  The Conversion 
Price shall be subject to adjustment from time to time as follows: 

          a.  COMMON STOCK ISSUED AT LESS THAN THE CONVERSION PRICE.  If the 
Company shall issue any Common Stock other than Excluded Stock (as 
hereinafter defined) without consideration or for a consideration per share 
less than the Conversion Price in effect immediately prior to such issuance, 
the Conversion Price in effect immediately prior to each such issuance shall 
immediately be reduced to the price determined by dividing (i) an amount 
equal to the sum of (A) the number of shares of Common Stock outstanding 
immediately prior to such issuance multiplied by the Conversion Price in 
effect immediately prior to such issuance and (B) the consideration, if any, 
received by the Company upon such issuance, by (ii) the total number of 
shares of Common Stock outstanding immediately after such issuance.  For the 
purposes of any adjustment of the Conversion Price pursuant to this Section 
7(a), the following provisions shall be applicable:

              (1) CASH.  In the case of the issuance of Common Stock for cash,
     the amount of the consideration received by the Company shall be deemed to
     be the amount of the cash proceeds received by the Company for such Common
     Stock before deducting therefrom any discounts, commissions, taxes or
     other expenses allowed, paid or incurred by the Company for any
     underwriting or otherwise in connection with the issuance and sale
     thereof.

              (2) CONSIDERATION OTHER THAN CASH.  In the case of the issuance
     of Common Stock (otherwise than upon the conversion of shares of capital
     stock or other securities of the Company) for a consideration in whole or
     in part other than cash, including securities acquired in exchange
     therefor (other than securities by their terms so exchangeable), the
     consideration other than cash shall be deemed to be the fair value thereof
     as determined by the Board; provided that such fair value as determined by
     the Board shall not exceed the aggregate Market Price of the shares of
     Common Stock being issued as of the date the Board authorizes the issuance
     of such shares.

                                                                         Page 16

              (3)  OPTIONS AND CONVERTIBLE SECURITIES.  In the case of the
     issuance of (i) options, warrants or other rights to purchase or acquire
     Common Stock (whether or not at the time exercisable), (ii) securities by
     their terms convertible into or exchangeable for Common Stock (whether or
     not at the time so convertible or exchangeable) or (iii) options, warrants
     or rights to purchase such convertible or exchangeable securities (whether
     or not at the time exercisable):

              (A)  the aggregate maximum number of shares of Common Stock
              deliverable upon exercise of such options, warrants or other
              rights to purchase or acquire Common Stock shall be deemed to
              have been issued at the time such options, warrants or rights
              were issued and for a consideration equal to the consideration
              (determined in the manner provided in subsections (1) and (2)
              above), if any, received by the Company upon the issuance of
              such options, warrants or rights plus the minimum purchase
              price provided in such options, warrants or rights for the
              Common Stock covered thereby;

              (B)  the aggregate maximum number of shares of Common Stock
              deliverable upon conversion of or in exchange for any such
              convertible or exchangeable securities, or upon the exercise of
              options, warrants or other rights to purchase or acquire such
              convertible or exchangeable securities and the subsequent
              conversion or exchange thereof, shall be deemed to have been
              issued at the time such securities were issued or such options,
              warrants or rights were issued and for a consideration equal to
              the consideration, if any, received by the Company for any such
              securities and related options, warrants or rights (excluding
              any cash received on account of accrued interest or accrued
              dividends), plus the additional consideration (determined in
              the manner provided in subsections (1) and (2) above), if any,
              to be received by the Company upon the conversion or exchange
              of such securities, or upon the exercise of any related
              options, warrants or rights to purchase or acquire such
              convertible or exchangeable securities and the subsequent
              conversion or exchange thereof; 

              (C)  on any change in the number of shares of Common Stock
              deliverable upon exercise of any such options, warrants or
              rights or conversion or exchange of such convertible or
              exchangeable securities or any change in the consideration to
              be received by the Company upon such exercise, conversion or
              exchange, including, but not limited to, a change resulting
              from the anti-dilution provisions thereof, the Conversion Price
              as then in effect shall forthwith be readjusted to such
              Conversion Price as

<PAGE>

                                                                         Page 17

              would have been obtained had an adjustment been made upon the 
              issuance of such options, warrants or rights not exercised prior 
              to such change, or of such convertible or exchangeable securities
              not converted or exchanged prior to such change, upon the basis 
              of such change;

              (D)  on the expiration or cancellation of any such options,
              warrants or rights, or the termination of the right to convert
              or exchange such convertible or exchangeable securities, if the
              Conversion Price shall have been adjusted upon the issuance
              thereof, the Conversion Price shall forthwith be readjusted to
              such Conversion Price as would have been obtained had an
              adjustment been made upon the issuance of such options,
              warrants, rights or such convertible or exchangeable securities
              on the basis of the issuance of only the number of shares of
              Common Stock actually issued upon the exercise of such options,
              warrants or rights, or upon the conversion or exchange of such
              convertible or exchangeable securities, if any; and

              (E)  if the Conversion Price shall have been adjusted upon
              the issuance of any such options, warrants, rights or
              convertible or exchangeable securities, no further adjustment
              of the Conversion Price shall be made for the actual issuance
              of Common Stock upon the exercise, conversion, or exchange
              thereof;

     provided, however, that no increase in the Conversion Price shall be made
     pursuant to subsections (A) or (B) of this subsection (3).

          b.   EXCLUDED STOCK.  For purposes of Section 7(a), "Excluded 
Stock" shall mean (i) shares of Common Stock issued or reserved for issuance 
by the Company as a stock dividend payable in shares of Common Stock, or upon 
any subdivision or split-up of the outstanding shares of Common Stock or 
Series E Preferred Stock, or upon conversion of shares of Series E Preferred 
Stock; (ii) shares of Common Stock reserved for issuance under options and 
warrants outstanding on the date hereof; (iii) 750,000 shares of Common Stock 
reserved for issuance to key employees and directors of the Corporation 
pursuant to the Company's employee stock option plan in effect as of the date 
hereof; (iv) shares of Series E Preferred Stock and shares of Common Stock 
issuable upon the conversion thereof, and (v) 77,520 shares of Common Stock 
issuable upon the conversion of the shares of Series C Convertible Preferred 
Stock outstanding on the date hereof.

          c.   STOCK DIVIDENDS, SUBDIVISIONS, RECLASSIFICATIONS OR 
COMBINATIONS. If the Company shall (i) declare a dividend or make a 
distribution on its Common Stock in shares of its Common Stock, (ii) 
subdivide or reclassify the outstanding shares of Common Stock into a greater 
number of shares, or (iii) combine or reclassify the outstanding Common Stock 
into a smaller number of shares, the Conversion Price in effect at the time 
of the record date for such dividend or distribution 

<PAGE>

                                                                         Page 18

or the effective date of such subdivision, combination or reclassification 
shall be proportionately adjusted so that the holder of any shares of Series 
E Preferred Stock surrendered for conversion after such date shall be 
entitled to receive the number of shares of Common Stock which he would have 
owned or been entitled to receive had such shares of Series E Preferred Stock 
been converted immediately prior to such date.  Successive adjustments in the 
Conversion Price shall be made whenever any event specified above shall occur.

          d.   OTHER DISTRIBUTIONS.  In case the Company shall fix a record 
date for the making of a distribution to all holders of shares of its Common 
Stock (i) of shares of any class other than its Common Stock, (ii) of 
evidence of indebtedness of the Company or any subsidiary of the Company, 
(iii) of assets, or (iv) of rights or warrants, in each such case the 
Conversion Price in effect immediately prior thereto shall be reduced 
immediately thereafter to the price determined by dividing (1) an amount 
equal to the difference resulting from (A) the number of shares of Common 
Stock outstanding on such record date multiplied by the Conversion Price per 
share on such record date, less (B) the fair market value (as determined by 
the Board) of said shares or evidences of indebtedness or assets or rights or 
warrants to be so distributed, by (2) the number of shares of Common Stock 
outstanding on such record date; PROVIDED, HOWEVER, that, so long as there 
are no Accumulated Dividends on the Series E Preferred Stock or the Series E 
Preferred Stock then outstanding for any previous Dividend Payment Date, the 
provisions of this Section 7(d) shall not apply to distributions consisting 
of cash dividends on the shares of Common Stock up to an amount equal to 50% 
of consolidated net income of the Company and its Subsidiaries as of the 
calendar year immediately preceding the proposed record date for such 
dividend. Any adjustment provided for by this Section 7(d) shall be made 
successively whenever such a record date is fixed.  

          e.   CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE.  In case of 
any consolidation with or merger of the Company with or into another 
corporation or other entity, or in case of any sale, lease or conveyance to 
another entity of the assets of the Company as an entirety or substantially 
as an entirety, each share of Series E Preferred Stock shall after the date 
of such consolidation, merger, sale, lease or conveyance be convertible into 
the number of shares of stock or other securities or property (including 
cash) to which the Common Stock issuable (at the time of such consolidation, 
merger, sale, lease or conveyance) upon conversion of such share of Series E 
Preferred Stock would have been entitled upon such consolidation, merger, 
sale, lease or conveyance; and in any such case, if necessary, the provisions 
set forth herein with respect to the rights and interests thereafter of the 
holders of the shares of Series E Preferred Stock shall be appropriately 
adjusted so as to be applicable, as nearly as may reasonably be, to any 
shares of stock or other securities or property thereafter deliverable on the 
conversion of the shares of Series E Preferred Stock.  Nothing in this 
Section 7(e) shall be construed in any way to derogate from the right of the 
holders of the Series E Preferred Stock to require the Company to repurchase 
their shares at the Change in Control Repurchase Price upon a Change in 
Control, as set forth in Section 8(c) hereof.

                                                                         Page 19

          f.   NOTICE TO HOLDERS.  In the event the Company shall propose to 
take any action of the type described in subsections (a), (c), (d), and (e) 
of this Section 7, the Company shall give notice to each holder of shares of 
Series E Preferred Stock, which notice shall specify the record date, if any, 
with respect to any such action and the approximate date on which such action 
is to take place.  Such notice shall also set forth such facts with respect 
thereto as shall be reasonably necessary to indicate the effect of such 
action on the Conversion Price and the number, kind or class of shares or 
other securities or property which shall be deliverable upon conversion of 
shares of Series E Preferred Stock.  In the case of any action which would 
require the fixing of a record date, such notice shall be given at least 10 
days prior to the date so fixed, and in the case of all other action, such 
notice shall be given at least 15 days prior to the taking of such proposed 
action.

          g.   STATEMENT REGARDING ADJUSTMENTS.  Upon the occurrence of each 
adjustment or readjustment of the Conversion Price of the Series E Preferred 
Stock pursuant to this Section 7, the Company shall compute such adjustment 
or readjustment in accordance with the terms hereof and prepare and furnish 
to each holder a certificate setting forth such adjustment or readjustment 
and showing in detail the facts upon which such adjustment or readjustment is 
based.  Each such statement shall be signed by the Company's public 
accountants.

          h.   TREASURY STOCK.  For the purposes of this Section 7, the sale 
or other disposition of any Common Stock theretofore held in the Company's 
treasury shall be deemed to be an issuance thereof.

          i.   GOOD FAITH.  The Company shall not, by amendment of its 
Certificate of Incorporation or through any reorganization, transfer of 
assets, consolidation, merger, dissolution, issuance or sale of securities or 
any other voluntary action, avoid or seek to avoid the observance or 
performance of any of the terms to be observed or performed hereunder by the 
Company, but shall at all times in good faith assist in the carrying out of 
all the provisions of this Section 7 and in the taking of all such action as 
may be necessary or appropriate in order to protect the conversion rights of 
the holders of the shares of Series E Preferred Stock shares against 
impairment of any kind.

     8.  VOTING RIGHTS; PROTECTIVE PROVISIONS; CHANGE OF CONTROL; REPURCHASE 
UPON CERTAIN EVENTS.

          a.   GENERAL.  Except as specifically set forth in the DGCL or 
provided in the balance of this Section 8, the holders of shares of Series E 
Preferred Stock shall not be entitled to any voting rights with respect to 
any matters voted upon by stockholders.

          b.   PROTECTIVE PROVISIONS.  So long as any shares of Series E 
Preferred Stock are outstanding, the written consent or the affirmative vote 
at a meeting called for that purpose of the holders of a majority of the 
shares of Series E Preferred Stock then outstanding, voting separately as a 
class, shall be necessary to validate or

<PAGE>

                                                                         Page 20

effectuate any of the following: (i) amend, repeal, alter or change any of 
the rights, preferences or privileges of the shares of Series E Preferred 
Stock; (ii) create (by reclassification of an existing class or series, or 
otherwise) any new class or series of shares of the Company's capital stock, 
except for classes or series of shares ranking, with respect to dividend 
rights and rights on any Liquidation Event, junior to the Series E Preferred 
Stock and the Series E Preferred Stock; (iii) issue any shares of the 
Company's capital stock, except for classes or series of shares ranking, with 
respect to dividend rights and rights on any Liquidation Event, junior to the 
Series E Preferred Stock and the Series E Preferred Stock; or (iv) take any 
action that materially and adversely affects the legal rights, preferences or 
privileges of the shares of Series E Preferred Stock.  At any time when there 
are any Accumulated Dividends or any Change in Control Special Dividend A 
accrued but unpaid for any reason, the holders of a majority of the shares of 
Series E Preferred Stock then outstanding, voting separately as a class, 
shall be necessary to validate or effectuate (i) any acquisition by the 
Company of all or substantially all of the assets of another Person, (ii) any 
acquisition by the Company of all or substantially all of the equity 
interests in any Person, and (iii) any merger or recapitalization transaction 
to which the Company is a party.

          c.   HOLDER'S ELECTION UPON CHANGE OF CONTROL.

              (1)  GENERALLY.  In the event of any Change in Control, each
     holder of shares of Series E Preferred Stock shall have the right, at such
     holder's election as set forth below, to receive in respect of each share
     owned by such holder a sum equal to (i) the then applicable Face Value,
     PLUS (ii) Accumulated Dividends, PLUS (iii) a "Change of Control Special
     Dividend A" equal to 18% of the then applicable Face Value.

              (2)  COMPANY'S NOTIFICATION OBLIGATION.

          (A)  The Company shall notify each holder of shares of Series E
          Preferred Stock in writing within 15 days before any Change in Control
          pursuant to a transaction to which the Company is a party (a "Company
          Change of Control Transaction") setting forth a description of the
          nature of the Change in Control and the date at which such Change in
          Control is anticipated to take place.  

          (B)  The Company shall notify each holder of shares of Series E
          Preferred Stock in writing as soon as the Company has Knowledge of any
          Change of Control pursuant to a transaction that is not a Company
          Change of Control Transaction (an "Other Change of Control
          Transaction") setting forth a description of the nature of the Change
          in Control and the date at which such Change in Control took place or
          is anticipated to take place.  

          (C)  The notices described in clauses (A) and (B) above are
          collectively denominated "Change in Control Notices".

<PAGE>

                                                                         Page 21

              (3)  HOLDER'S ELECTION.  Within five (5) days after receipt of
     the Change of Control Notice, each holder shall notify the Company in
     writing whether or not such holder will require such holder's shares of
     Series E Preferred Stock to be redeemed by the Company pursuant to this
     Section.  If a holder does not timely notify the Company in writing
     pursuant to the previous sentence, such holder will be deemed to have
     waived its right to require such holder's shares of Series E Preferred
     Stock to be redeemed by the Company pursuant to this Section; provided,
     however, that such waiver shall only apply to the Change of Control
     relating to the relevant Change of Control Notice, and not any subsequent
     Change of Control or Change of Control Notice.

              (4)  COMPANY CHANGE OF CONTROL.  The Company shall redeem the
     shares of each holder of Series E Preferred Stock so electing such a
     redemption in connection with a Company Change of Control Transaction by
     making cash payments to such holder in respect of each share owned by such
     holder as follows: (i) a sum equal to the then applicable Face Value PLUS
     Accumulated Dividends on or prior to the date of the Company Change in
     Control Transaction as a condition precedent to the effectiveness of such
     Company Change in Control Transaction, and (ii) a sum equal to the Change
     in Control Special Dividend A as soon as funds are legally available for
     payment thereof after the date of the Company Change in Control
     Transaction.  Any Company Change of Control Transaction shall be void and
     of no force and effect if the payments set forth in clause (i) of this
     Section 8(c)(4) are not made on or prior to the date of such Company Change
     in Control Transaction.

              (5)  OTHER CHANGES OF CONTROL.  The Company shall redeem the
     shares of each holder of Series E Preferred Stock so electing such a
     redemption in connection with an Other Change of Control Transaction as
     promptly as practicable after receipt of such holder's notice of such
     election by making cash payments to such holder in respect of each share
     owned by such holder as follows: (i) a sum equal to the then applicable
     Face Value PLUS Accumulated Dividends plus a sum equal to the Change in
     Control Special Dividend A as soon as funds are legally available for
     payment thereof after the date of the Other Change in Control Transaction.

          d.  SPECIAL REPURCHASE EVENTS.

              (1)  REPRESENTATIONS.  The Company represents and warrants to
     each holder of shares of Series E Preferred Stock as follows:

          (A)  Except as otherwise disclosed in the Disclosure Schedule to the
          Stock Purchase Agreement (as such term is defined therein), neither
          the Company nor any of its Affiliates since inception has provided any
          research, educational or study grants or other financial support of
          any kind to any hospital, physician, or health care provider.

          (B)  Neither the Company nor any of its Affiliates since inception has
          received notice that the Company or any Subsidiary has been, or to the
          Company's knowledge has been, the subject of any investigative
          proceeding before any federal or state regulatory authority or the
          agent of any such authority, including without limitation federal and
          state health authorities.

          (C)  Neither the Company nor any Affiliate, nor the officers,
          directors, employees or agents of any of the Company or any Affiliate,
          and none of the Persons who provide professional services under
          agreements with any of the Company or any Affiliate as agents of such
          entities have engaged in any activities which are prohibited, or are

          Health and Medical Plan of the Uniformed Services statute ("CHAMPUS"),

          regulations or related state or local statutes or which are prohibited
          by any private accrediting organization from which the Company or any

          to the following activities:

              (a)  knowingly and willfully making or causing to be made a false
          statement or representation of a material fact in any application for
          any benefit or payment;

              (b)  knowingly and willfully making or causing to be made any
          false statement or representation of a material fact for use in

     of Series E Preferred Stock are outstanding:

          (A)  The operations of the Company and its Affiliates will be
          conducted in accordance with all Applicable Laws, including, without

          have a Material Adverse Effect on the Company or any Subsidiary.

          (B)  Without limiting the generality of the foregoing, the operations

     be true on the Issue Date in any material respect, or the Company's breach
     of any of the covenants set forth in Section 8(d)(2), shall be a "Special

          shall send copies of such Holder Special Repurchase Event Notice to
          all other holders, if any, of shares of Series E Preferred Stock.  A
          Company Special Repurchase Event Notice or a Holder Special Repurchase
          Event Notice shall be denominated herein a "Special Repurchase Event
          Notice".  

          (B)  Within ten (10) days after receipt of any Special Repurchase
          Event Notice (or a copy thereof), each holder shall send a written
          notice to the Company either electing to have such holder's shares
          repurchased pursuant to the provisions of this Section 8(d) or
          declining to so elect (the "Special Repurchase Event Election"). 
          Within 10 days after receipt of each holder's Special Repurchase Event
          Election, the Company shall repurchase each share of Series E
          Preferred Stock of each such holder electing to have such holder's
          shares repurchased pursuant to the provisions of this Section 8(d) at
          a price per share equal to the Face Amount per share plus Accumulated

     shares of Series E Preferred Stock set forth in this Section 8(d) with
     respect to any misrepresentation or breach of covenant contained herein
     shall be without prejudice to any other remedies of such holders for such
     misrepresentation or breach, including without limitation (in the case of
     General Electric) any remedies of General Electric under the Stock Purchase
     Agreement.

                                    RECITALS

     WHEREAS, the Company and GE desire to amend the Note Purchase Agreement and
GE's Notes, as they relate to the Company and GE only (and not as they relate to
DVI), to permit the conversion of such Notes into shares of the Company's Series
E Preferred Stock (as defined below), on the terms and conditions as set forth
below; and

     WHEREAS, the Company and the Holders desire to amend certain covenants and
definitions in the Note Purchase Agreement;

     NOW, THEREFORE, in consideration of the premises and the agreements,
provisions and covenants herein contained, the applicable parties hereto (as
specified below) agree as follows:


<PAGE>

     SECTION 1.     CONVERSION OF GE'S NOTES
     
     The Company and GE (including, for all purposes of this Section 1, GE's
Affiliates, as such term is defined in that certain Bridge Loan Agreement, dated
as of December 31, 1996, between the Company and GE), and not DVI, which is not
a party to the agreements contained in this Section 1, agree as follows:
     
     1.1  CONVERSION OF NOTES.  GE shall have the right, at its option, at any
time from and after January 1, 1998, to convert, subject to the terms and
provisions of this Section 1, all or any portion of the face amount of its Notes
into such number of fully paid and non-assessable shares of the Company's Series
E Preferred Stock, with the rights and privileges as set forth in the attached
Exhibit 1 (the "SERIES E PREFERRED STOCK"), as results from dividing (i) the
Notional Amount (as defined below) corresponding to the face amount of the Notes
to be converted, by (ii) the Face Amount (as defined in the Series E Preferred
Stock) of the Series E Preferred Stock.  For purposes of this Eleventh
Amendment, with respect to the Notes, "Notional Amount" shall mean the principal
amount of a note (the "NOTIONAL OBLIGATION") in the initial notional principal
amount of $9,000,000 as of November 6, 1996 bearing an annual interest rate of
10.00%, compounded monthly, that would remain unpaid as of the Notes Conversion
Date (as defined below) if all payments actually made under the Notes to the
Holder after November 6, 1996 through the Notes Conversion Date, including
payments of both interest and principal, were applied to the Notional
Obligation, applying such payments first to interest on the Notional Obligation
and then to principal of the Notional Obligation, with negative amortization
reflected, if applicable.  Such conversion shall be deemed to have been made at
the close of business on the date that a Note or Notes representing the Notional
Amount of Notes to be converted shall have been surrendered for conversion (it
being understood that each dollar in Notional Amount of Notes is represented by
a principal amount of Notes equal to the result of dividing (x) the number 1, by
(y) the ratio of the aggregate remaining Notional Amount of the Notes to the
aggregate remaining face amount of the Notes at the Notes Conversion Date, as
such remaining face amount is calculated from time to time in accordance with
the provisions of the Note Purchase Agreement) and written notice shall have
been received as provided in Section 1.2 (the "NOTES CONVERSION DATE"), so that
the person or persons entitled to receive the shares of Series E Preferred Stock
upon conversion of the Notes shall be treated for all purposes as having become
the record holder or holder of such shares of Series E Preferred Stock at such
time.

     1.2  NOTICE TO COMPANY.  In order to convert all or any portion of its
Notes into shares of Series E Preferred Stock, GE shall deliver the Notes to be
converted to the Company at its principal office, together with written notice
that it elects to convert those Notes into shares of Series E Preferred Stock in
accordance with the provisions of this Section 1.  Such notice shall specify the
amount of Notes to be converted and the name or names in which GE wishes


                                      -2-


<PAGE>

the certificates for shares of Series E Preferred Stock to be registered, 
together with the address or addresses of the person or persons so named, and, 
if so required by the Company, be accompanied by a written instrument or 
instruments of transfer in form satisfactory to the Company, duly executed by GE
or by its attorney duly authorized in writing.

     1.3  DELIVERY OF CERTIFICATE.  As promptly as practicable after the
surrender as hereinabove provided of Notes for conversion into shares of Series
E Preferred Stock, the Company shall deliver or cause to be delivered GE, or
GE's designees, certificates representing the number of fully paid and
non-assessable shares of Series E Preferred Stock into which the Notes are
entitled to be converted, together with a cash adjustment in respect of any
fraction of a share to which GE shall be entitled (as provided below), and, if
less than the entire face amount of a Note surrendered is to be converted, a new
Note for the balance of the Note not so converted.  So long as any Notes remain
unpaid, the Company shall not close its Series E Preferred Stock transfer books.
The issuance of certificates for shares of Series E Preferred Stock upon the
conversion of Notes shall be made without charge to GE for any tax in respect of
the issuance of such certificates (other than any tax if the shares of Series E
Preferred Stock are to be registered in a name different from that of the
registered holder of the Note).

     1.4  FRACTIONAL SHARES.  No fractional shares of Series E Preferred Stock
or scrip representing fractional shares of Series E Preferred Stock shall be
issued upon any conversion of any Notes, but, in lieu thereof, there shall be
paid an amount in cash equal to the Market Price (as defined in the Series E
Preferred Stock) of the number shares of Common Stock into which such fraction
of a share of Series E Preferred Stock would be otherwise convertible into
according to the terms of the Series E Preferred Stock with any resulting
fractions of Common Stock being paid cash in accordance with the Series E
Preferred provisions pertaining to fractional shares.

     1.5  RESERVATION OF SHARES.  The Company shall at all times reserve and
keep available out of its authorized but unissued shares of Series E Preferred
Stock, solely for the purpose of effecting the conversion of Notes, the full
number of whole shares of Series E Preferred Stock then deliverable upon the
conversion of all the Notes.  The Company shall take at all times such corporate
action as shall be necessary in order that the Company may validly and legally
issue fully paid and non-assessable shares of Series E Preferred Stock upon the
conversion of the Notes in accordance with the provisions of this Section 1.

     1.6  RETIREMENT OF NOTES.  Any Notes converted pursuant to the provisions
of this Section 1 shall be deemed retired, repaid and fully satisfied.


                                      -3-


<PAGE>

     1.7  RIGHTS AS EQUITY HOLDER.  GE shall not be entitled to any rights as a
stockholder of the Company pursuant to the Note Purchase Agreement until, and to
the extent that, the Notes have been converted into shares of Series E Preferred
Stock in accordance with the provisions hereof.

     1.8  NOTES.  GE's Notes shall be restated to reflect the provisions of this
Section 1 in substantially the form attached as Exhibit 2.

     1.9  TRANSFERABILITY.  The conversion rights provided by this Section 1 of
this Eleventh Amendment may be exercised only by GE or one or more Affiliates
(as defined above) of GE and no other transferee or assignee of the Note may

Purchase Agreement:

          "Capital Expenditure Adjustment Amount" shall mean, for any Capital
Expenditure Period corresponding to a capital raising transaction described in
clause (i) following, the positive amount, if any, of (i) net cash proceeds from
issuances of Common Stock or other securities convertible into Common Stock or
other non-redeemable equity securities of the Company minus (ii) cash expended
during such Capital Expenditure Period by the Company or its Majority-Owned
Subsidiaries in connection with business acquisitions (including without
limitation acquisitions of substantially all of the assets of a Person permitted
under this Agreement); PROVIDED, HOWEVER, that any cash expenditures
constituting Capital Expenditures for such Capital Expenditure Period that are
already included in the calculation of the total amount of Capital Expenditures
for such Capital Expenditure Period for purposes of determining compliance with
Section 10.08 hereof (without considering the Capital Expenditure Adjustment
Amount) shall only be included once in such total amount, regardless of whether
such Capital Expenditures arise in connection with a business acquisition.  If
the Company could properly include a Capital Expenditure within the general
limitation under Section 10.08 hereof and/or under an available Capital
Expenditure Adjustment Amount, the Company shall be entitled in its discretion
to select the allocation of such Capital Expenditure.  To the extent that
amounts expended are included under clause (ii) of the foregoing definition,
such amounts shall be deducted from the amount described in clause (i) on a
chronological basis (I.E., the first such amount deducted will be the first of
such amounts expended, and so on).

          "Capital Expenditure Period" means, with respect to each capital
raising transaction described in clause (i) of the definition of Capital
Expenditure Adjustment Amount, the two-year period beginning with the date that
net proceeds with respect to such transaction are received by the Company.

     (ii) The definition of "Fiscal Year" in Section 11.01 of the Note Purchase
Agreement is deleted and replaced with the following definition:

          "Fiscal Year" shall mean the fiscal year of the Company, which shall
be the twelve (12) month period ending on December 31 in each year or such other
period as the Board of Directors of the Company may adopt."


                                      -9-

     (iii)     The definitions of "Consolidated Net Tangible Assets,"
"Consolidated Operating Income Before Depreciation," "Current Equipment
Obligations," "Currently Owned-Equipment," and "Permitted Investments" in
Section 11.01 of the Note Purchase Agreement are deleted.

     SECTION 3.     CONSIDERATION FOR AMENDMENT

     date being herein referred to as a "Dividend Payment Date"), commencing 
     on June 30, 1997.  The quarterly period between consecutive Dividend 
     Payment Dates shall hereinafter be referred to as a "Dividend Period."

(and any full cash Special Dividends) are not paid to the holders of all 
outstanding shares of Series D Preferred Stock, and funds available shall be 
insufficient to permit payment in full in cash to all such holders of the 
preferential amounts to which they are they entitled, the entire amount

holders of the Series D Preferred Stock ratably in proportion to the full 
amount to which they would otherwise be respectively entitled, and any 
remainder not paid in cash to the holders of the Series D Preferred Stock

or declared, with additional dividends thereon to accrue at the rate of eight

                                                                        Page 9

percent (8%) per annum for each succeeding full Dividend Period during which 
such dividends shall remain unpaid.  Unpaid dividends for any period less 
than a full Dividend Period shall cumulate on a day-to-day basis and shall be 
computed on the basis of a 360 day year.  "Accumulated Dividends" shall mean, 
as of any date, all Regular Dividends and Special Dividends that are either 
undeclared or unpaid as of such date.

         e.   RESTRICTIONS WITH RESPECT TO JUNIOR SECURITIES.  

            (1)  So long as any Series D Preferred Stock shall remain 
     outstanding, no regular periodic cash dividend whatsoever shall be 
     declared or paid upon or set apart for payment on any class of Junior 
     Securities, unless in each instance at such time no Accumulated 
     Dividends, Change in Control Dividend A or Change in Control Dividend B 
     shall be accrued but unpaid.  

            (2)  So long as any Series D Preferred Stock shall remain 
     outstanding, no shares of Junior Securities shall be redeemed or 
     purchased for cash by the Company or any parent or subsidiary thereof 
     nor shall any moneys be paid to or made available for a sinking fund for 
     redemption or purchase of any shares of Junior Securities.

            (3)  The restrictions set forth in Sections 4(e)(1) and 4(e)(2) 
     above shall not apply to (i) up to $100,000 per calendar year applied to 
     redemption or purchase by the Company of Junior Securities owned by 
     employees of the Company in connection with the separation of such 
     employees from their employment with the Company, or (ii) any particular 
     cash dividend, redemption or purchase if the holders of a majority of 
     then outstanding shares of Series D Preferred Stock consent in writing 
     to the declaration or payment of such cash dividend, redemption or 
     purchase, as the case may be.

    5.   LIQUIDATION PREFERENCE.

         a.   GENERAL.  Upon a Liquidation Event, the holders of Series D 
Preferred Stock then outstanding shall be entitled to be paid, out of the 
assets of the Company available for distribution to its shareholders, whether 
from capital, surplus or earnings ("Available Assets"), before any payment 
shall be made in respect of any Junior Security, an amount equal to the Face 
Amount per share PLUS an amount equal to all Accumulated Dividends, if any 
(in the aggregate, the "Liquidation Preference Amount").  If upon a 
Liquidation Event, the Available Assets shall be insufficient to pay the 
holders of the Series D Preferred Stock the full Liquidation Preference 
Amount, the holders of the Series D Preferred Stock shall share ratably in 
any distribution of assets according to the respective amounts which would be 
payable in respect of the shares held by them upon such distribution if all 
amounts payable on or with respect to said shares were paid in full.  

         b.   NOTICE REQUIRED.  Written notice of any voluntary or 
involuntary Liquidation Event, stating the payment date and the place where 
the distributable amount shall be payable, shall be given by mail, postage 
prepaid, not less than thirty (30) days prior to the payment date stated 
therein, to the holders of record of the Series D Preferred Stock at their 
respective addresses as the same shall then appear on the books of the 
Company.  

    6.   CONVERSION. 

         a.   EXERCISE OF CONVERSION RIGHT.  Each holder of Series D 
Preferred Stock shall have the right, at its option, at any time from the 
Issue Date through December 31, 2006, to convert, subject to the terms and 
provisions of this Section 6, all or any portion of its Series D Preferred 
Stock then outstanding into such number of fully paid and non-assessable 
shares of Common Stock as results from dividing (i) the sum of (A) the Face 
Amount of all shares of Series D Preferred Stock to be converted plus (B) any 
Accumulated Dividends on such shares, by (ii) the applicable Conversion Price 

<PAGE>

                                                                        Page 10


(as defined below) on the Conversion Date (as defined below).   Such 
conversion shall be deemed to have been made at the close of business on the 
date that the certificate or certificates for shares of Series D Preferred 
Stock shall have been surrendered for conversion and written notice shall 
have been received as provided in Section 6(b) (the "Conversion Date"), so 
that the person or persons entitled to receive the shares of Common Stock 
upon conversion of such shares of Series D Preferred Stock shall be treated 
for all purposes as having become the record holder or holders of such shares 
of Common Stock at such time and such conversion shall be at the Conversion 
Price in effect at such time.  Upon conversion of any shares of Series D 
Preferred Stock pursuant to this Section 6, the rights of the holder of such 
shares upon the Conversion Date shall be the rights of a holder of Common 
Stock only, and each such holder shall not have any rights in its former 
capacity as a holder of shares of Series D Preferred Stock. 

         b.   NOTICE TO COMPANY.  In order to convert all or any portion of 
its outstanding Series D Preferred Stock into shares of Common Stock, the 
holder of such Series D Preferred Stock shall deliver the shares of Series D 
Preferred Stock to be converted to the Company at its principal office, 
together with written notice that it elects to convert those shares of Series 
D Preferred Stock into shares of Common Stock in accordance with the 
provisions of this Section 6.  Such notice shall specify the number of shares 
of Series D Preferred Stock to be converted and the name or names in which 
the holder wishes the certificates for shares of Common Stock to be 
registered, together with the address or addresses of the person or persons 
so named, and, if so required by the Company, shall be accompanied by a 
written instrument or instruments of transfer in form satisfactory to the 
Company, duly executed by the registered holder of the shares of Series D 
Preferred Stock to be converted or by its attorney duly authorized in writing.

         c.   DELIVERY OF CERTIFICATE.  As promptly as practicable after the 
surrender as hereinabove provided of shares of Series D Preferred Stock for 
conversion into shares of Common Stock, the Company shall deliver or cause to 
be delivered to the holder, or the holder's designees, certificates 
representing the number of fully paid and non-assessable shares of Common 
Stock into which the shares of Series D Preferred Stock are entitled to be 
converted, together with a cash adjustment in respect of any fraction of a 
share to which the holder shall be entitled as provided in Section 6(d), and, 
if less than the entire number of shares of Series D Preferred Stock 
represented by the certificate or certificates surrendered is to be 
converted, a new certificate for the number of shares of Series D Preferred 
Stock not so converted.  So long as any shares of Series D Preferred Stock 
remain outstanding, the Company shall not close its Common Stock transfer 
books.  The issuance of certificates for shares of Common Stock upon the 
conversion of shares of Series D Preferred Stock shall be made without charge 
to the holder for any tax in respect of the issuance of such certificates 
(other than any transfer, withholding or other tax if the shares of Common 
Stock are to be registered in a name different from that of the registered 
holder of Series D Preferred Stock).

         d.   FRACTIONAL SHARES.  No fractional shares of Common Stock or 
scrip representing fractional shares of Common Stock shall be issued upon any 
conversion of any shares of Series D Preferred Stock, but, in lieu thereof, 
there shall be paid an amount in cash equal to the same fraction of the 
Market Price of a whole share of Common Stock as of the Conversion Date. 

<PAGE>

                                                                        Page 11

         e.   RESERVATION OF SHARES.  The Company shall at all times reserve 
and keep available out of its authorized but unissued shares of Common Stock, 
solely for the purpose of effecting the conversion of shares of Series D 
Preferred Stock, the full number of whole shares of Common Stock then 
deliverable upon the conversion of all shares of Series D Preferred Stock 
then outstanding.  The Company shall take at all times such corporate action 
as shall be necessary in order that the Company may validly and legally issue 
fully paid and non-assessable shares of Common Stock upon the conversion of 
shares of Series D Preferred Stock in accordance with the provisions of this 
Section 6.

         f.   REGISTRATION.  If any shares of Common Stock to be reserved for 
the purpose of conversion of Series D Preferred Stock require registration or 
listing with, or approval of, any governmental authority, stock exchange or 
other regulatory body under any federal or state law or regulation or 
otherwise, before such shares may be validly issued or delivered upon 
conversion, the Company shall, in good faith and as expeditiously as 
possible, endeavor to secure such registration, listing or approval, as the 
case may be.

         g.   SHARES VALIDLY ISSUED AND NON-ASSESSABLE.  All shares of Common 
Stock that may be issued upon conversion of the Series D Preferred Stock 
shall upon issuance by the Company be validly issued, fully paid and 
nonassessable and free from all taxes, liens and charges with respect to the 
issuance thereof.

         h.   RETIREMENT OF SHARES.  Any shares of Series D Preferred Stock 
converted pursuant to the provisions of this Section 6 shall be retired and 
given the status of authorized and unissued Preferred Stock, undesignated as 
to series, subject to reissuance by the Company as shares of Preferred Stock 
of one or more series, as may be determined from time to time by the Board.

    7.   CONVERSION PRICE.  As used herein, the "Conversion Price" shall 
initially be $6.00 per share of Common Stock, subject to adjustment as set 
forth below.  No payment or adjustment shall be made for any dividends on the 
Common Stock issuable in such conversion.  The Conversion Price shall be 
subject to adjustment from time to time as follows: 

         a.   COMMON STOCK ISSUED AT LESS THAN THE CONVERSION PRICE.  If the 
Company shall issue any Common Stock other than Excluded Stock (as 
hereinafter defined) without consideration or for a consideration per share 
less than the Conversion Price in effect immediately prior to such issuance, 
the Conversion Price in effect immediately prior to each such issuance shall 
immediately be reduced to the price determined by dividing (i) an amount 
equal to the sum of (A) the number of shares of Common Stock outstanding 
immediately prior to such issuance multiplied by the Conversion Price in 
effect immediately prior to such issuance and (B) the consideration, if any, 
received by the Company upon such issuance, by (ii) the total number of 
shares of Common Stock outstanding immediately after such issuance.  For the 
purposes of any adjustment of the Conversion Price pursuant to this Section 
7(a), the following provisions shall be applicable:

             (1)  CASH.  In the case of the issuance of Common Stock for 
     cash, the amount of the consideration received by the Company shall be 
     deemed to be the amount of the cash proceeds received by the Company for 
     such Common Stock before deducting therefrom any discounts, commissions, 
     taxes or other expenses allowed, paid or incurred by the Company for any 

<PAGE>

                                                                        Page 12

     underwriting or otherwise in connection with the issuance and sale 
     thereof.

             (2)  CONSIDERATION OTHER THAN CASH.  In the case of the issuance 
     of Common Stock (otherwise than upon the conversion of shares of capital 
     stock or other securities of the Company) for a consideration in whole 
     or in part other than cash, including securities acquired in exchange 
     therefor (other than securities by their terms so exchangeable), the 
     consideration other than cash shall be deemed to be the fair value 
     thereof as determined by the Board; provided that such fair value as 
     determined by the Board shall not exceed the aggregate Market Price of 
     the shares of Common Stock being issued as of the date the Board 
     authorizes the issuance of such shares.

             (3)  OPTIONS AND CONVERTIBLE SECURITIES.  In the case of the 
     issuance of (i) options, warrants or other rights to purchase or acquire 
     Common Stock (whether or not at the time exercisable), (ii) securities 
     by their terms convertible into or exchangeable for Common Stock 
     (whether or not at the time so convertible or exchangeable) or (iii) 
     options, warrants or rights to purchase such convertible or exchangeable 
     securities (whether or not at the time exercisable):

                 (A)  the aggregate maximum number of shares of Common Stock 
          deliverable upon exercise of such options, warrants or other rights 
          to purchase or acquire Common Stock shall be deemed to have been 
          issued at the time such options, warrants or rights were issued and 
          for a consideration equal to the consideration (determined in the 
          manner provided in subsections (1) and (2) above), if any, received 
          by the Company upon the issuance of such options, warrants or 
          rights plus the minimum purchase price provided in such options, 
          warrants or rights for the Common Stock covered thereby;

                 (B)  the aggregate maximum number of shares of Common Stock 
          deliverable upon conversion of or in exchange for any such 
          convertible or exchangeable securities, or upon the exercise of 
          options, warrants or other rights to purchase or acquire such 
          convertible or exchangeable securities and the subsequent 
          conversion or exchange thereof, shall be deemed to have been issued 
          at the time such securities were issued or such options, warrants 
          or rights were issued and for a consideration equal to the 
          consideration, if any, received by the Company for any such 
          securities and related options, warrants or rights (excluding any 
          cash received on account of accrued interest or accrued dividends), 
          plus the additional consideration (determined in the manner 
          provided in subsections (1) and (2) above), if any, to be received 
          by the Company upon the conversion or exchange of such securities, 
          or upon the exercise of any related options, warrants or rights to 
          purchase or acquire such convertible or exchangeable securities and 
          the subsequent conversion or exchange thereof; 

                 (C)  on any change in the number of shares of Common Stock 
          deliverable upon exercise of any such options, 

<PAGE>

                                                                        Page 13


          warrants or rights or conversion or exchange of such convertible or 
          exchangeable securities or any change in the consideration to be 
          received by the Company upon such exercise, conversion or exchange, 
          including, but not limited to, a change resulting from the 
          anti-dilution provisions thereof, the Conversion Price as then in 
          effect shall forthwith be readjusted to such Conversion Price as 
          would have been obtained had an adjustment been made upon the 
          issuance of such options, warrants or rights not exercised prior to 
          such change, or of such convertible or exchangeable securities not 
          converted or exchanged prior to such change, upon the basis of such 
          change;

                 (D)  on the expiration or cancellation of any such options, 
          warrants or rights, or the termination of the right to convert or 
          exchange such convertible or exchangeable securities, if the 
          Conversion Price shall have been adjusted upon the issuance 
          thereof, the Conversion Price shall forthwith be readjusted to such 
          Conversion Price as would have been obtained had an adjustment been 
          made upon the issuance of such options, warrants, rights or such 
          convertible or exchangeable securities on the basis of the issuance 
          of only the number of shares of Common Stock actually issued upon 
          the exercise of such options, warrants or rights, or upon the 
          conversion or exchange of such convertible or exchangeable 
          securities, if any; and

                 (E)  if the Conversion Price shall have been adjusted upon 
          the issuance of any such options, warrants, rights or convertible 
          or exchangeable securities, no further adjustment of the Conversion 
          Price shall be made for the actual issuance of Common Stock upon 
          the exercise, conversion, or exchange thereof;

          provided, however, that no increase in the Conversion Price shall 
be made pursuant to subsections (A) or (B) of this subsection (3).

         b.   EXCLUDED STOCK.  For purposes of Section 7(a), "Excluded Stock" 
shall mean (i) shares of Common Stock issued or reserved for issuance by the 
Company as a stock dividend payable in shares of Common Stock, or upon any 
subdivision or split up of the outstanding shares of Common Stock or Series D 
Preferred Stock, or upon conversion of shares of the Series D Preferred 
Stock, (ii) under options and warrants outstanding on the date hereof, (iii) 
750,000 shares of Common Stock reserved for issuance to key employees and 
directors of the Company pursuant to the Company's employee stock option plan 
in effect as of the date hereof; (iv) shares of Series E Preferred Stock and 
shares of Common Stock issuable upon the conversion thereof, and (v) 77,520 
shares of Common Stock issuable upon the conversion of the shares of Series C 
Convertible Preferred Stock outstanding on the date hereof.

         c.   STOCK DIVIDENDS, SUBDIVISIONS, RECLASSIFICATIONS OR 
COMBINATIONS.  If the Company shall (i) declare a dividend or make a 
distribution on its Common Stock in shares of its Common Stock, (ii) 
subdivide or reclassify the 

<PAGE>

                                                                        Page 14

outstanding shares of Common Stock into a greater number of shares, or (iii) 
combine or reclassify the outstanding Common Stock into a smaller number of 
shares, the Conversion Price in effect at the time of the record date for 
such dividend or distribution or the effective date of such subdivision, 
combination or reclassification shall be proportionately adjusted so that the 
holder of any shares of Series D Preferred Stock surrendered for conversion 
after such date shall be entitled to receive the number of shares of Common 
Stock which he would have owned or been entitled to receive had such shares 
of Series D Preferred Stock been converted immediately prior to such date.  
Successive adjustments in the Conversion Price shall be made whenever any 
event specified above shall occur.

         d.   OTHER DISTRIBUTIONS.  In case the Company shall fix a record 
date for the making of a distribution to all holders of shares of its Common 
Stock (i) of shares of any class other than its Common Stock, (ii) of 
evidence of indebtedness of the Company or any subsidiary of the Company, 
(iii) of assets, or (iv) of rights or warrants, in each such case the 
Conversion Price in effect immediately prior thereto shall be reduced 
immediately thereafter to the price determined by dividing (1) an amount 
equal to the difference resulting from (A) the number of shares of Common 
Stock outstanding on such record date multiplied by the Conversion Price per 
share on such record date, less (B) the fair market value (as determined by 
the Board) of said shares or evidences of indebtedness or assets or rights or 
warrants to be so distributed, by (2) the number of shares of Common Stock 
outstanding on such record date; PROVIDED, HOWEVER, that, so long as there 
are no Accumulated Dividends on the Series D Preferred Stock or the Series E 
Preferred Stock then outstanding for any previous Dividend Payment Date, the 
provisions of this Section 7(d) shall not apply to distributions consisting 
of cash dividends on the shares of Common Stock up to an amount equal to 50% 
of consolidated net income of the Company and its Majority-Owned Subsidiaries 
as of the calendar year immediately preceding the proposed record date for 
such dividend.  Any adjustment provided for by this Section 7(d) shall be 
made successively whenever such a record date is fixed.  

         e.   CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE.  In case of 
any consolidation with or merger of the Company with or into another 
corporation or other entity, or in case of any sale, lease or conveyance to 
another entity of the assets of the Company as an entirety or substantially 
as an entirety, each share of Series D Preferred Stock shall after the date 
of such consolidation, merger, sale, lease or conveyance be convertible into 
the number of shares of stock or other securities or property (including 
cash) to which the Common Stock issuable (at the time of such consolidation, 
merger, sale, lease or conveyance) upon conversion of such share of Series D 
Preferred Stock would have been entitled upon such consolidation, merger, 
sale, lease or conveyance; and in any such case, if necessary, the provisions 
set forth herein with respect to the rights and interests thereafter of the 
holders of the shares of Series D Preferred Stock shall be appropriately 
adjusted so as to be applicable, as nearly as may reasonably be, to any 
shares of stock or other securities or property thereafter deliverable on the 
conversion of the shares of Series D Preferred Stock.  Nothing in this 
Section 7(e) shall be construed in any way to derogate from the right of the 
holders of the Series D Preferred Stock to require the Company to repurchase 
their shares at the Change in Control Repurchase Price upon a Change in 
Control, as set forth in Section 8(c) hereof.

                                                                        Page 15

         f.   NOTICE TO HOLDERS.  In the event the Company shall propose to 
take any action of the type described in subsections (a), (c), (d), and (e) 
of this Section 7, the Company shall give notice to each holder of shares of 
Series D Preferred Stock, which notice shall specify the record date, if any, 
with respect to any such action and the approximate date on which such action 
is to take place.  Such notice shall also set forth such facts with respect 
thereto as shall be reasonably necessary to indicate the effect of such 
action on the Conversion Price and the number, kind or class of shares or 
other securities or property which shall be deliverable upon conversion of 
shares of Series D Preferred Stock.  In the case of any action which would 
require the fixing of a record date, such notice shall be given at least 10 
days prior to the date so fixed, and in the case of all other action, such 
notice shall be given at least 15 days prior to the taking of such proposed 
action.

         g.   STATEMENT REGARDING ADJUSTMENTS.  Upon the occurrence of each 
adjustment or readjustment of the Conversion Price of the Series D Preferred 
Stock pursuant to this Section 7, the Company shall compute such adjustment 
or readjustment in accordance with the terms hereof and prepare and furnish 
to each holder a certificate setting forth such adjustment or readjustment 
and showing in detail the facts upon which such adjustment or readjustment is 
based.  Each such statement shall be signed by the Company's public 
accountants.

         h.   TREASURY STOCK.  For the purposes of this Section 7, the sale 
or other disposition of any Common Stock theretofore held in the Company's 
treasury shall be deemed to be an issuance thereof.

         i.   GOOD FAITH.  The Company shall not, by amendment of its 
Certificate of Incorporation or through any reorganization, transfer of 
assets, consolidation, merger, dissolution, issuance or sale of securities or 
any other voluntary action, avoid or seek to avoid the observance or 
performance of any of the terms to be observed or performed hereunder by the 
Company, but shall at all times in good faith assist in the carrying out of 
all the provisions of this Section 7 and in the taking of all such action as 
may be necessary or appropriate in order to protect the conversion rights of 
the holders of the shares of Series D Preferred Stock shares against 
impairment of any kind.

    8.   VOTING RIGHTS; PROTECTIVE PROVISIONS; CHANGE OF CONTROL; SPECIAL 
REPURCHASE EVENTS.

         a.   GENERAL.  Except as specifically set forth in the DGCL or 
provided in the balance of this Section 8, the holders of shares of Series D 
Preferred Stock shall not be entitled to any voting rights with respect to 
any matters voted upon by stockholders.

         b.   PROTECTIVE PROVISIONS.  So long as any shares of Series D 
Preferred Stock are outstanding, the written consent or the affirmative vote 
at a meeting called for that purpose of the holders of a majority of the 
shares of Series D Preferred Stock then outstanding, voting separately as a 
class, shall be necessary to validate or effectuate any of the following: (i) 
amend, repeal, alter or change any of the rights, preferences or privileges 
of the shares of Series D Preferred Stock; (ii) create (by reclassification 
of an existing class or series, or otherwise) any new class or series of 
shares of the Company's capital stock, except for classes or series of shares 
ranking, with respect to dividend rights and rights on any Liquidation Event, 
junior to the Series D Preferred Stock and the Series E Preferred Stock; 
(iii) issue any shares of the 

<PAGE>

                                                                        Page 16

Company's capital stock, except for classes or series of shares ranking, with 
respect to dividend rights and rights on any Liquidation Event, junior to the 
Series D Preferred Stock and the Series E Preferred Stock; or (iv) take any 
action that materially and adversely affects the legal rights, preferences or 
privileges of the shares of Series D Preferred Stock.  At any time when there 
are any Accumulated Dividends or any Change in Control Special Dividend A 
accrued but unpaid for any reason, the holders of a majority of the shares of 
Series D Preferred Stock then outstanding, voting separately as a class, 
shall be necessary to validate or effectuate (i) any acquisition by the 
Company of all or substantially all of the assets of another Person, (ii) any 
acquisition by the Company of all or substantially all of the equity 
interests in any Person, and (iii) any merger or recapitalization transaction 
to which the Company is a party.

         c.   HOLDER'S ELECTION UPON CHANGE OF CONTROL.  

             (1)  GENERALLY.  In the event of any Change in Control, each 
     holder of shares of Series D Preferred Stock shall have the right, at 
     such holder's election as set forth below, to receive in respect of each 
     share owned by such holder a sum equal to (i) the then applicable Face 
     Value, PLUS (ii) Accumulated Dividends, PLUS (iii) a "Change of Control 
     Special Dividend A" equal to 18% of the then applicable Face Value.  

             (2)  COMPANY'S NOTIFICATION OBLIGATION.  

                 (A)  The Company shall notify each holder of shares of 
          Series D Preferred Stock in writing within 15 days before any 
          Change in Control pursuant to a transaction to which the Company is 
          a party (a "Company Change of Control Transaction") setting forth a 
          description of the nature of the Change in Control and the date at 
          which such Change in Control is anticipated to take place.  

                 (B)  The Company shall notify each holder of shares of 
          Series D Preferred Stock in writing as soon as the Company has 
          Knowledge of any Change of Control pursuant to a transaction that 
          is not a Company Change of Control Transaction (an "Other Change of 
          Control Transaction") setting forth a description of the nature of 
          the Change in Control and the date at which such Change in Control 
          took place or is anticipated to take place.  

                 (C)  The notices described in clauses (A) and (B) above are 
          collectively denominated "Change in Control Notices".

             (3)  HOLDER'S ELECTION.  Within five (5) days after receipt of

     writing whether or not such holder will require such holder's shares of 
     Series D Preferred Stock to be redeemed by the Company pursuant to this 
     Section.  If a holder does not timely notify the Company in writing 
     pursuant to the previous sentence, such holder will be deemed to have 
     waived its right to require such holder's shares of Series D Preferred 
     Stock to be redeemed by the Company pursuant to this Section; provided, 
     however, that such waiver shall only apply to the Change of Control 
     relating to the relevant Change of Control Notice, and not any 
     subsequent Change of Control or Change of Control Notice.

             (4)  COMPANY CHANGE OF CONTROL.  The Company shall redeem the 
     shares of each holder of Series D Preferred Stock so electing such a 
     redemption in connection with a Company Change of Control Transaction by

     making cash payments to such holder in respect of each share owned by 
     such holder as follows: (i) a sum equal to the then applicable Face 
     Value PLUS Accumulated Dividends on or prior to the date of the Company 
     Change in Control Transaction as a condition precedent to the 
     effectiveness of such Company Change in Control Transaction, and (ii) a 
     sum equal to the Change in Control Special Dividend A as soon as funds 
     are legally available for payment thereof after the date of the Company 
     Change in Control Transaction.  Any Company Change of Control 
     Transaction shall be void and of no force and effect if the payments set 
     forth in clause (i) of this Section 8(c)(4) are not made on or prior to 
     the date of such Company Change in Control Transaction.

             (5)  OTHER CHANGES OF CONTROL.  The Company shall redeem the 
     shares of each holder of Series D Preferred Stock so electing such a 
     redemption in connection with an Other Change of Control Transaction as 
     promptly as practicable after receipt of such holder's notice of such 
     election by making cash payments to such holder in respect of each share 
     owned by such holder as follows: (i) a sum equal to the then applicable 
     Face Value PLUS Accumulated Dividends plus a sum equal to the Change in 
     Control Special Dividend A as soon as funds are legally available for 
     payment thereof after the date of the Other Change in Control 
     Transaction.

          Repurchase Event Notice, the Company shall send copies of such 
          Holder Special Repurchase Event Notice to all other holders, if 
          any, of shares of Series D Preferred Stock.  A Company Special 
          Repurchase Event Notice or a Holder Special Repurchase Event Notice 
          shall be denominated herein a "Special Repurchase Event Notice".  

                 (B)  Within ten (10) days after receipt of any Special 
          Repurchase Event Notice (or a copy thereof), each holder shall send

          holder's shares repurchased pursuant to the provisions of this 
          Section 8(d) or declining to so elect (the "Special Repurchase 
          Event Election").  Within 10 days after receipt of each holder's 
          Special Repurchase Event Election, the Company shall repurchase 
          each share of Series D Preferred Stock of each such holder electing 
          to have such holder's shares repurchased pursuant to the provisions

redeemed will cease to accrue on the Redemption Date.  No defect in any such 
notice to any holder of Series D Preferred Stock shall affect the validity of 
the proceedings for the redemption of any other shares of such Series D 
Preferred Stock.

         f.   RETIREMENT OF SHARES.  Any shares of Series D Preferred Stock 
redeemed pursuant to the provisions of this Section 9 shall be retired and

to pay all amounts payable to the holders of shares of Series D Preferred 
Stock due in respect of a redemption pursuant to Section 9(b) hereof prior on

              (1)  Regular Dividends shall be cumulative from the Issue Date
     and shall be payable in arrears, when and as declared by the Board, on
     March 31, June 30, September 30, and December 31 of each year (each such
     date being herein referred to as a "Dividend Payment Date"), commencing on
     the first such date immediately following the Issue Date.  The quarterly
     period between consecutive Dividend Payment Dates shall hereinafter be
     referred to as a "Dividend Period."  Each such Regular Dividend shall be
     paid to the holders of record of the Series E Preferred Stock as their
     names appear on the share register of the Company on the corresponding
     Record Date.  As used above, the term "Record Date" means, with respect to
     the Regular Dividend payable on March 31, June 30, September 30 and
     December 31, respectively, of each year, the preceding March 15, June 15,
     September 15 and December 15, or such other record date designated by the
     Board of the Company with respect to the Regular Dividend payable on such
     respective Dividend Payment Date.  Dividends on account of arrears for any
     past Dividend Periods may be declared and paid at any time, without
     reference to any Dividend Payment Date, to holders of record on such date,
     not exceeding 50 days preceding the payment date thereof, as may be fixed
     by the Board.

              (2)  Special Dividends shall be cumulative from the date of the
     first day of the first full calendar month after any Special Dividend Event
     Trigger Date and shall be payable in arrears, when and as declared by the
     Board, on each Dividend Payment Date.  Each such Special Dividend shall be
     paid to the holders of record of the Series E Preferred Stock as their
     names appear on the share register of the Company on the corresponding
     Record Date.  Special Dividends on account of arrears for any past Dividend
     Periods may be declared and paid at any time, without reference to any
     Dividend Payment Date, to holders of record on such date, not exceeding 50
     days preceding the payment date thereof, as may be fixed by the Board.

          d.   ACCUMULATION.  In the event that full cash Regular Dividends (and
any full cash Special Dividends) are not paid to the holders of all outstanding
shares of Series E Preferred Stock, and funds available shall be insufficient to
permit payment in full in cash to all such holders of the preferential amounts
to which they are they entitled, the entire amount available for payment of cash
dividends shall be distributed among the holders of the Series E Preferred Stock
ratably in proportion to the full

<PAGE>

                                                                         Page 12

amount to which they would otherwise be respectively entitled, and any 
remainder not paid in cash to the holders of the Series E Preferred Stock 
shall cumulate as provided in this subsection 4(d). If, on any Dividend 
Payment Date, the holders of the Series E Preferred Stock shall not have 
received the full Regular Dividends and full Special Dividends provided for 
in this Section 4, then such dividends shall cumulate, whether or not earned 
or declared, with additional dividends thereon to accrue at the rate of eight 
percent (8%) per annum for each succeeding full Dividend Period during which 
such dividends shall remain unpaid.  Unpaid dividends for any period less 
than a full Dividend Period shall cumulate on a day-to-day basis and shall be 
computed on the basis of a 360 day year.  "Accumulated Dividends" shall mean, 
as of any date, all Regular Dividends and Special Dividends that are either 
undeclared or unpaid as of such date.

          e.  RESTRICTION WITH RESPECT TO JUNIOR SECURITIES. 

              (1)  So long as any Series E Preferred Stock shall remain
     outstanding, no regular periodic cash dividend whatsoever shall be declared
     or paid upon or set apart for payment on any class of Junior Securities,
     unless in each instance at such time no Accumulated Dividends, Change in
     Control Dividend A or Change in Control Dividend B shall be accrued but
     unpaid. 

              (2)  So long as any Series E Preferred Stock shall remain
     outstanding, no shares of Junior Securities shall be redeemed or purchased
     for cash by the Company or any parent or subsidiary thereof nor shall any
     moneys be paid to or made available for a sinking fund for redemption or
     purchase of any shares of Junior Securities.
     
              (3)  The restrictions set forth in Sections 4(e)(1) and 4(e)(2)
     above shall not apply to (i) up to $100,000 per calendar year applied to
     redemption or purchase by the Company of Junior Securities owned by
     employees of the Company in connection with the separation of such
     employees from their employment with the Company, or (ii) any particular
     cash dividend, redemption or purchase if the holders of a majority of then
     outstanding shares of Series E Preferred Stock consent in writing to the
     declaration or payment of such cash dividend, redemption or purchase, as
     the case may be.

     5.   LIQUIDATION PREFERENCE.

          a.  GENERAL.  Upon a Liquidation Event, the holders of Series E 
Preferred Stock then outstanding shall be entitled to be paid, out of the 
assets of the Company available for distribution to its shareholders, whether 
from capital, surplus or earnings ("Available Assets"), before any payment 
shall be made in respect of any Junior Security, an amount equal to the Face 
Amount per share PLUS an amount equal to all Accumulated Dividends, if any 
(in the aggregate, the "Liquidation Preference Amount").  If upon a 
Liquidation Event, the Available Assets shall be insufficient to pay the 
holders of the Series E Preferred Stock the full Liquidation Preference 
Amount, the holders of the Series E Preferred Stock shall share ratably in 
any distribution of assets according to the respective amounts which would be 
payable in respect of the shares

<PAGE>

                                                                         Page 13

held by them upon such distribution if all amounts payable on or with respect 
to said shares were paid in full.  

          b.   NOTICE REQUIRED.  Written notice of any voluntary or 
involuntary Liquidation Event, stating the payment date and the place where 
the distributable amount shall be payable, shall be given by mail, postage 
prepaid, not less than thirty (30) days prior to the payment date stated 
therein, to the holders of record of the Series E Preferred Stock at their 
respective addresses as the same shall then appear on the books of the 
Company.  

     6.   CONVERSION. 

          a.   EXERCISE OF CONVERSION RIGHT.  Each holder of Series E 
Preferred Stock shall have the right, at its option, at any time from the 
Issue Date through December 31, 2006, to convert, subject to the terms and 
provisions of this Section 6, all or any portion of its Series E Preferred 
Stock then outstanding into such number of fully paid and non-assessable 
shares of Common Stock as results from dividing (i) the sum of (A) the Face 
Amount of all shares of Series E Preferred Stock to be converted plus (B) any 
Accumulated Dividends on such shares, by (ii) the applicable Conversion Price 
(as defined below) on the Conversion Date (as defined below).   Such 
conversion shall be deemed to have been made at the close of business on the 
date that the certificate or certificates for shares of Series E Preferred 
Stock shall have been surrendered for conversion and written notice shall 
have been received as provided in Section 6(b) (the "Conversion Date"), so 
that the person or persons entitled to receive the shares of Common Stock 
upon conversion of such shares of Series E Preferred Stock shall be treated 
for all purposes as having become the record holder or holders of such shares 
of Common Stock at such time and such conversion shall be at the Conversion 
Price in effect at such time.  Upon conversion of any shares of Series E 
Preferred Stock pursuant to this Section 6, the rights of the holder of such 
shares upon the Conversion Date shall be the rights of a holder of Common 
Stock only, and each such holder shall not have any rights in its former 
capacity as a holder of shares of Series E Preferred Stock. 

          b.   NOTICE TO COMPANY.  In order to convert all or any portion of 
its outstanding Series E Preferred Stock into shares of Common Stock, the 
holder of such Series E Preferred Stock shall deliver the shares of Series E 
Preferred Stock to be converted to the Company at its principal office, 
together with written notice that it elects to convert those shares of Series 
E Preferred Stock into shares of Common Stock in accordance with the 
provisions of this Section 6.  Such notice shall specify the number of shares 
of Series E Preferred Stock to be converted and the name or names in which 
the holder wishes the certificates for shares of Common Stock to be 
registered, together with the address or addresses of the person or persons 
so named, and, if so required by the Company, shall be accompanied by a 
written instrument or instruments of transfer in form satisfactory to the 
Company, duly executed by the registered holder of the shares of Series E 
Preferred Stock to be converted or by its attorney duly authorized in writing.

<PAGE>

                                                                         Page 14

          c.   DELIVERY OF CERTIFICATE.  As promptly as practicable after the 
surrender as hereinabove provided of shares of Series E Preferred Stock for 
conversion into shares of Common Stock, the Company shall deliver or cause to 
be delivered to the holder, or the holder's designees, certificates 
representing the number of fully paid and non-assessable shares of Common 
Stock into which the shares of Series E Preferred Stock are entitled to be 
converted, together with a cash adjustment in respect of any fraction of a 
share to which the holder shall be entitled as provided in Section 6(d), and, 
if less than the entire number of shares of Series E Preferred Stock 
represented by the certificate or certificates surrendered is to be 
converted, a new certificate for the number of shares of Series E Preferred 
Stock not so converted.  So long as any shares of Series E Preferred Stock 
remain outstanding, the Company shall not close its Common Stock transfer 
books.  The issuance of certificates for shares of Common Stock upon the 
conversion of shares of Series E Preferred Stock shall be made without charge 
to the holder for any tax in respect of the issuance of such certificates 
(other than any transfer, withholding or other tax if the shares of Common 
Stock are to be registered in a name different from that of the registered 
holder of Series E Preferred Stock).

          d.   FRACTIONAL SHARES.  No fractional shares of Common Stock or 
scrip representing fractional shares of Common Stock shall be issued upon any 
conversion of any shares of Series E Preferred Stock, but, in lieu thereof, 
there shall be paid an amount in cash equal to the same fraction of the 
Market Price of a whole share of Common Stock as of the Conversion Date. 

          e.   RESERVATION OF SHARES.  The Company shall at all times reserve 
and keep available out of its authorized but unissued shares of Common Stock, 
solely for the purpose of effecting the conversion of shares of Series E 
Preferred Stock, the full number of whole shares of Common Stock then 
deliverable upon the conversion of all shares of Series E Preferred Stock 
then outstanding.  The Company shall take at all times such corporate action 
as shall be necessary in order that the Company may validly and legally issue 
fully paid and non-assessable shares of Common Stock upon the conversion of 
shares of Series E Preferred Stock in accordance with the provisions of this 
Section 6.

          f.   REGISTRATION.  If any shares of Common Stock to be reserved 
for the purpose of conversion of Series E Preferred Stock require 
registration or listing with, or approval of, any governmental authority, 
stock exchange or other regulatory body under any federal or state law or 
regulation or otherwise, before such shares may be validly issued or 
delivered upon conversion, the Company shall, in good faith and as 
expeditiously as possible, endeavor to secure such registration, listing or 
approval, as the case may be.

          g.   SHARES VALIDLY ISSUED AND NON-ASSESSABLE.  All shares of 
Common Stock that may be issued upon conversion of the Series E Preferred 
Stock shall upon issuance by the Company be validly issued, fully paid and 
nonassessable and free from all taxes, liens and charges with respect to the 
issuance thereof.

<PAGE>

                                                                         Page 15

          h.   RETIREMENT OF SHARES.  Any shares of Series E Preferred Stock 
converted pursuant to the provisions of this Section 6 shall be retired and 
given the status of authorized and unissued Preferred Stock, undesignated as 
to series, subject to reissuance by the Company as shares of Preferred Stock 
of one or more series, as may be determined from time to time by the Board.

     7.   CONVERSION PRICE.  As used herein, the "Conversion Price" shall 
initially be the greater of (i) the Average Market Price as of the Issue Date 
and (ii) the Base Conversion Price, subject to adjustment as set forth below. 
The "Base Conversion Price" shall be $6.00 per share of Common Stock (as such 
Common Stock is constituted as of the date of this Certificate, such amount 
to be proportionately adjusted in the event of any stock dividend, stock 
split, subdivision, reclassification, combination or similar event with 
respect to the Common Stock).  No payment or adjustment shall be made for any 
dividends on the Common Stock issuable in such conversion.  The Conversion 
Price shall be subject to adjustment from time to time as follows: 

          a.  COMMON STOCK ISSUED AT LESS THAN THE CONVERSION PRICE.  If the 
Company shall issue any Common Stock other than Excluded Stock (as 
hereinafter defined) without consideration or for a consideration per share 
less than the Conversion Price in effect immediately prior to such issuance, 
the Conversion Price in effect immediately prior to each such issuance shall 
immediately be reduced to the price determined by dividing (i) an amount 
equal to the sum of (A) the number of shares of Common Stock outstanding 
immediately prior to such issuance multiplied by the Conversion Price in 
effect immediately prior to such issuance and (B) the consideration, if any, 
received by the Company upon such issuance, by (ii) the total number of 
shares of Common Stock outstanding immediately after such issuance.  For the 
purposes of any adjustment of the Conversion Price pursuant to this Section 
7(a), the following provisions shall be applicable:

              (1) CASH.  In the case of the issuance of Common Stock for cash,
     the amount of the consideration received by the Company shall be deemed to
     be the amount of the cash proceeds received by the Company for such Common
     Stock before deducting therefrom any discounts, commissions, taxes or
     other expenses allowed, paid or incurred by the Company for any
     underwriting or otherwise in connection with the issuance and sale
     thereof.

              (2) CONSIDERATION OTHER THAN CASH.  In the case of the issuance
     of Common Stock (otherwise than upon the conversion of shares of capital
     stock or other securities of the Company) for a consideration in whole or
     in part other than cash, including securities acquired in exchange
     therefor (other than securities by their terms so exchangeable), the
     consideration other than cash shall be deemed to be the fair value thereof
     as determined by the Board; provided that such fair value as determined by
     the Board shall not exceed the aggregate Market Price of the shares of
     Common Stock being issued as of the date the Board authorizes the issuance
     of such shares.

<PAGE>

                                                                         Page 16

              (3)  OPTIONS AND CONVERTIBLE SECURITIES.  In the case of the
     issuance of (i) options, warrants or other rights to purchase or acquire
     Common Stock (whether or not at the time exercisable), (ii) securities by
     their terms convertible into or exchangeable for Common Stock (whether or
     not at the time so convertible or exchangeable) or (iii) options, warrants
     or rights to purchase such convertible or exchangeable securities (whether
     or not at the time exercisable):

              (A)  the aggregate maximum number of shares of Common Stock
              deliverable upon exercise of such options, warrants or other
              rights to purchase or acquire Common Stock shall be deemed to
              have been issued at the time such options, warrants or rights
              were issued and for a consideration equal to the consideration
              (determined in the manner provided in subsections (1) and (2)
              above), if any, received by the Company upon the issuance of
              such options, warrants or rights plus the minimum purchase
              price provided in such options, warrants or rights for the
              Common Stock covered thereby;

              (B)  the aggregate maximum number of shares of Common Stock
              deliverable upon conversion of or in exchange for any such
              convertible or exchangeable securities, or upon the exercise of
              options, warrants or other rights to purchase or acquire such
              convertible or exchangeable securities and the subsequent
              conversion or exchange thereof, shall be deemed to have been
              issued at the time such securities were issued or such options,
              warrants or rights were issued and for a consideration equal to
              the consideration, if any, received by the Company for any such
              securities and related options, warrants or rights (excluding
              any cash received on account of accrued interest or accrued
              dividends), plus the additional consideration (determined in
              the manner provided in subsections (1) and (2) above), if any,
              to be received by the Company upon the conversion or exchange
              of such securities, or upon the exercise of any related
              options, warrants or rights to purchase or acquire such
              convertible or exchangeable securities and the subsequent
              conversion or exchange thereof; 

              (C)  on any change in the number of shares of Common Stock
              deliverable upon exercise of any such options, warrants or
              rights or conversion or exchange of such convertible or
              exchangeable securities or any change in the consideration to
              be received by the Company upon such exercise, conversion or
              exchange, including, but not limited to, a change resulting
              from the anti-dilution provisions thereof, the Conversion Price
              as then in effect shall forthwith be readjusted to such
              Conversion Price as

<PAGE>

                                                                         Page 17

              would have been obtained had an adjustment been made upon the 
              issuance of such options, warrants or rights not exercised prior 
              to such change, or of such convertible or exchangeable securities
              not converted or exchanged prior to such change, upon the basis 
              of such change;

              (D)  on the expiration or cancellation of any such options,
              warrants or rights, or the termination of the right to convert
              or exchange such convertible or exchangeable securities, if the
              Conversion Price shall have been adjusted upon the issuance
              thereof, the Conversion Price shall forthwith be readjusted to
              such Conversion Price as would have been obtained had an
              adjustment been made upon the issuance of such options,
              warrants, rights or such convertible or exchangeable securities
              on the basis of the issuance of only the number of shares of
              Common Stock actually issued upon the exercise of such options,
              warrants or rights, or upon the conversion or exchange of such
              convertible or exchangeable securities, if any; and

              (E)  if the Conversion Price shall have been adjusted upon
              the issuance of any such options, warrants, rights or
              convertible or exchangeable securities, no further adjustment
              of the Conversion Price shall be made for the actual issuance
              of Common Stock upon the exercise, conversion, or exchange
              thereof;

     provided, however, that no increase in the Conversion Price shall be made
     pursuant to subsections (A) or (B) of this subsection (3).

          b.   EXCLUDED STOCK.  For purposes of Section 7(a), "Excluded 
Stock" shall mean (i) shares of Common Stock issued or reserved for issuance 
by the Company as a stock dividend payable in shares of Common Stock, or upon 
any subdivision or split-up of the outstanding shares of Common Stock or 
Series E Preferred Stock, or upon conversion of shares of Series E Preferred 
Stock; (ii) shares of Common Stock reserved for issuance under options and 
warrants outstanding on the date hereof; (iii) 750,000 shares of Common Stock 
reserved for issuance to key employees and directors of the Corporation 
pursuant to the Company's employee stock option plan in effect as of the date 
hereof; (iv) shares of Series E Preferred Stock and shares of Common Stock 
issuable upon the conversion thereof, and (v) 77,520 shares of Common Stock 
issuable upon the conversion of the shares of Series C Convertible Preferred 
Stock outstanding on the date hereof.

          c.   STOCK DIVIDENDS, SUBDIVISIONS, RECLASSIFICATIONS OR 
COMBINATIONS. If the Company shall (i) declare a dividend or make a 
distribution on its Common Stock in shares of its Common Stock, (ii) 
subdivide or reclassify the outstanding shares of Common Stock into a greater 
number of shares, or (iii) combine or reclassify the outstanding Common Stock 
into a smaller number of shares, the Conversion Price in effect at the time 
of the record date for such dividend or distribution 

<PAGE>

                                                                         Page 18

or the effective date of such subdivision, combination or reclassification 
shall be proportionately adjusted so that the holder of any shares of Series 
E Preferred Stock surrendered for conversion after such date shall be 
entitled to receive the number of shares of Common Stock which he would have 
owned or been entitled to receive had such shares of Series E Preferred Stock 
been converted immediately prior to such date.  Successive adjustments in the 
Conversion Price shall be made whenever any event specified above shall occur.

          d.   OTHER DISTRIBUTIONS.  In case the Company shall fix a record 
date for the making of a distribution to all holders of shares of its Common 
Stock (i) of shares of any class other than its Common Stock, (ii) of 
evidence of indebtedness of the Company or any subsidiary of the Company, 
(iii) of assets, or (iv) of rights or warrants, in each such case the 
Conversion Price in effect immediately prior thereto shall be reduced 
immediately thereafter to the price determined by dividing (1) an amount 
equal to the difference resulting from (A) the number of shares of Common 
Stock outstanding on such record date multiplied by the Conversion Price per 
share on such record date, less (B) the fair market value (as determined by 
the Board) of said shares or evidences of indebtedness or assets or rights or 
warrants to be so distributed, by (2) the number of shares of Common Stock 
outstanding on such record date; PROVIDED, HOWEVER, that, so long as there 
are no Accumulated Dividends on the Series E Preferred Stock or the Series E 
Preferred Stock then outstanding for any previous Dividend Payment Date, the 
provisions of this Section 7(d) shall not apply to distributions consisting 
of cash dividends on the shares of Common Stock up to an amount equal to 50% 
of consolidated net income of the Company and its Subsidiaries as of the 
calendar year immediately preceding the proposed record date for such 
dividend. Any adjustment provided for by this Section 7(d) shall be made 
successively whenever such a record date is fixed.  

          e.   CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE.  In case of 
any consolidation with or merger of the Company with or into another 
corporation or other entity, or in case of any sale, lease or conveyance to 
another entity of the assets of the Company as an entirety or substantially 
as an entirety, each share of Series E Preferred Stock shall after the date 
of such consolidation, merger, sale, lease or conveyance be convertible into 
the number of shares of stock or other securities or property (including 
cash) to which the Common Stock issuable (at the time of such consolidation, 
merger, sale, lease or conveyance) upon conversion of such share of Series E 
Preferred Stock would have been entitled upon such consolidation, merger, 
sale, lease or conveyance; and in any such case, if necessary, the provisions 
set forth herein with respect to the rights and interests thereafter of the 
holders of the shares of Series E Preferred Stock shall be appropriately 
adjusted so as to be applicable, as nearly as may reasonably be, to any 
shares of stock or other securities or property thereafter deliverable on the 
conversion of the shares of Series E Preferred Stock.  Nothing in this 
Section 7(e) shall be construed in any way to derogate from the right of the 
holders of the Series E Preferred Stock to require the Company to repurchase 
their shares at the Change in Control Repurchase Price upon a Change in 
Control, as set forth in Section 8(c) hereof.

                                                                         Page 19

          f.   NOTICE TO HOLDERS.  In the event the Company shall propose to 
take any action of the type described in subsections (a), (c), (d), and (e) 
of this Section 7, the Company shall give notice to each holder of shares of 
Series E Preferred Stock, which notice shall specify the record date, if any, 
with respect to any such action and the approximate date on which such action 
is to take place.  Such notice shall also set forth such facts with respect 
thereto as shall be reasonably necessary to indicate the effect of such 
action on the Conversion Price and the number, kind or class of shares or 
other securities or property which shall be deliverable upon conversion of 
shares of Series E Preferred Stock.  In the case of any action which would 
require the fixing of a record date, such notice shall be given at least 10 
days prior to the date so fixed, and in the case of all other action, such 
notice shall be given at least 15 days prior to the taking of such proposed 
action.

          g.   STATEMENT REGARDING ADJUSTMENTS.  Upon the occurrence of each 
adjustment or readjustment of the Conversion Price of the Series E Preferred 
Stock pursuant to this Section 7, the Company shall compute such adjustment 
or readjustment in accordance with the terms hereof and prepare and furnish 
to each holder a certificate setting forth such adjustment or readjustment 
and showing in detail the facts upon which such adjustment or readjustment is

     holder of shares of Series E Preferred Stock shall have the right, at such
     holder's election as set forth below, to receive in respect of each share
     owned by such holder a sum equal to (i) the then applicable Face Value,
     PLUS (ii) Accumulated Dividends, PLUS (iii) a "Change of Control Special
     Dividend A" equal to 18% of the then applicable Face Value.

              (2)  COMPANY'S NOTIFICATION OBLIGATION.

          (A)  The Company shall notify each holder of shares of Series E
          Preferred Stock in writing within 15 days before any Change in Control
          pursuant to a transaction to which the Company is a party (a "Company
          Change of Control Transaction") setting forth a description of the
          nature of the Change in Control and the date at which such Change in
          Control is anticipated to take place.  

          (B)  The Company shall notify each holder of shares of Series E
          Preferred Stock in writing as soon as the Company has Knowledge of any

          Transaction") setting forth a description of the nature of the Change

              (3)  HOLDER'S ELECTION.  Within five (5) days after receipt of
     the Change of Control Notice, each holder shall notify the Company in
     writing whether or not such holder will require such holder's shares of
     Series E Preferred Stock to be redeemed by the Company pursuant to this
     Section.  If a holder does not timely notify the Company in writing
     pursuant to the previous sentence, such holder will be deemed to have
     waived its right to require such holder's shares of Series E Preferred
     Stock to be redeemed by the Company pursuant to this Section; provided,
     however, that such waiver shall only apply to the Change of Control
     relating to the relevant Change of Control Notice, and not any subsequent

     holder as follows: (i) a sum equal to the then applicable Face Value PLUS
     Accumulated Dividends on or prior to the date of the Company Change in
     Control Transaction as a condition precedent to the effectiveness of such
     Company Change in Control Transaction, and (ii) a sum equal to the Change
     in Control Special Dividend A as soon as funds are legally available for
     payment thereof after the date of the Company Change in Control
     Transaction.  Any Company Change of Control Transaction shall be void and
     of no force and effect if the payments set forth in clause (i) of this
     Section 8(c)(4) are not made on or prior to the date of such Company Change
     in Control Transaction.

              (5)  OTHER CHANGES OF CONTROL.  The Company shall redeem the
     shares of each holder of Series E Preferred Stock so electing such a
     redemption in connection with an Other Change of Control Transaction as

     election by making cash payments to such holder in respect of each share
     owned by such holder as follows: (i) a sum equal to the then applicable
     Face Value PLUS Accumulated Dividends plus a sum equal to the Change in
     Control Special Dividend A as soon as funds are legally available for
     payment thereof after the date of the Other Change in Control Transaction.

          Election, the Company shall repurchase each share of Series E
          Preferred Stock of each such holder electing to have such holder's

                    AMENDED AND RESTATED STANDSTILL AGREEMENT

     This Amended and Restated Standstill Agreement (the "Agreement") is 
entered into as of December 31, 1996, between Alliance Imaging, Inc., a 
Delaware corporation (the "Company"), and each of the entities identified on 
the signature pages hereto (each a "Holder" and collectively the "Holders").

                                    RECITALS

     A.   As of the date of this Agreement, the Company and the holders of 
the Company's issue of 7.50% Senior Subordinated Debentures due 2005 and 
Series A 6.0% Cumulative Preferred Stock (together, the "Securities") are 
completing transactions whereby the Securities are being repurchased by the 
Company for cash (the "Refinancing Transaction").

     B.   Each of the Holders is the owner, as of the date hereof, of the 
number of shares (including shares issuable upon the exercise of warrants 
currently held by each such Holder) (the "Restricted Shares") of Common 
Stock, $.01 par value per share (the "Stock"), set forth beneath its name on 
the signature pages hereto.

     C.   The parties acknowledge and agree that the Company and its 
subsidiaries, as of the date hereof and after giving effect to previous 
restructuring transactions and the Refinancing Transaction, will have the 
right to certain valuable federal and state net operating loss tax 
carryforwards (collectively, the "NOL").

     D.   The parties desire to enter into this Agreement in order to set 
forth their agreement concerning certain restrictions on the purchase, sale 
or transfer of the Restricted Shares and other shares of Stock, in order to 
minimize the potential that a purchase, sale or transfer would result in a 
limitation on the use or otherwise affect adversely the value of the NOL.

     E.   Concurrently with the execution of this Agreement, the Company is 
offering to enter into those certain Amended and Restated Standstill 
Agreements with the previous holders of the Company's Securities, Richard N. 
Zehner and DLJ Capital Corporation (the "Other Standstill Agreements").  This 
Agreement amends, restates and supersedes in its entirety that certain 
Standstill Agreement between the Company and the Holders dated as of December 
31, 1994, and, to the extent that the parties to the Other Standstill 
Agreements elect to enter into their respective Amended and Restated 
Standstill Agreements, then such Amended and Restated Standstill Agreements 
shall likewise amend, restate and supersede in their entirety the preexisting 


<PAGE>

Standstill Agreements between the Company and the applicable counterparties 
dated as of December 31, 1994 (the "Preexisting Standstill Agreements").

     NOW, THEREFORE, in consideration of the foregoing and other good and 
valuable consideration, receipt of which hereby is acknowledged, the parties 
hereby agree as follows:

     1.   STANDSTILL PROVISIONS.  Each Holder agrees that, at all times from 
and after the date of this Agreement and through January 31, 1998, it shall 
not, except as permitted in Section 2 hereof, take any of the following 
actions, and it shall not cause its respective shareholders, officers, 
directors, Subsidiaries and other Affiliates (as such terms are defined in 
Section 3 below) to take any of the following actions in such Holder's name 
or on such Holder's behalf, and shall cause its respective Subsidiaries and 
Affiliates not to, in all instances whether directly or indirectly and 
whether alone, jointly or collectively:

          (a)  acquire, agree to acquire, offer to acquire or own or 
otherwise hold any Stock of the Company or any other Voting Stock (as defined 
below) of the Company, excluding only the continued holding of the Restricted 
Shares; or

          (b)  sell or otherwise transfer, agree to sell or otherwise transfer
or offer to sell or otherwise transfer any of the Restricted Shares or other
shares of Voting Stock.

     2.   PERMITTED TRANSFERS.  Notwithstanding the provisions of Section 1,
this Agreement does not prohibit the following:

          (a)  a transfer of Restricted Shares by any Holder to any Person in 
connection with (i) a sale of all or substantially all of the assets of the 
Company and its subsidiaries to a Person which is not an Affiliate of the 
Company or (ii) a reorganization, merger, consolidation or other transaction 
or transactions (whether or not the Company is a party thereto and 
specifically including, without limitation, open market purchases of 
securities) as a result of which any person or entity or "group" of persons 
and/or entities becomes the "beneficial owner" (as those terms are defined in 
and construed by judicial authority under Rule 13d-3 promulgated under the 
Exchange Act, as that Rule may be amended from time to time) of Stock and/or 
options, warrants or other rights to acquire Stock and/or securities 
convertible into or exchangeable or exercisable for Stock, representing in 
the aggregate greater than 50% of the ordinary voting power of the Company in 
the election of directors (any such event described in clauses (i) and (ii) 
of this Section 2 being a "Change of Control"), provided that such transfer 
is effective no earlier than the consummation date of such Change of Control; 
PROVIDED, HOWEVER, that prior to such transfer becoming effective or any 
agreement or commitment for such 

                                       -2-

<PAGE>

transfer being made or becoming effective, the Holder shall give written 
notice to the Company, in order to provide the Company with the opportunity 
to analyze the effects of the proposed transfer on the NOL and to discuss the 
same with the Holder, and such proposed transfer shall not become effective 
earlier than ten (10) business days following the date that such written 
notice is delivered. Notwithstanding anything in the foregoing to the 
contrary, nothing herein shall prohibit any transfer of Restricted Shares by 
any Holder to the Company;

          (b)  the sale by any Holder of not more than one percent (1%) of 
such Holder's Restricted Shares during any calendar month, beginning with 
January 1997; or

          (c)  the purchase of Stock by any Holder issuable upon exercise of 
warrants currently held by such Holder.

as amended, including the rules and regulations thereunder.

          (c)  "Person" shall mean any individual, partnership, firm,

of the Company which are entitled to vote generally in the election of 
directors of the Company and the term "Voting Stock" shall also mean all 
other securities which are convertible into, exchangeable for or exercisable

<PAGE>

provision therein which is substantially identical to a provision contained

the Company also offers concurrently to amend this Agreement in a like manner.

          4.5  SUCCESSORS AND ASSIGNS.  No party shall be entitled to assign 
any of its rights or obligations hereunder.  Subject to the foregoing, this

or more counterparts, and by each party on a separate counterpart, each of

                    AMENDED AND RESTATED STANDSTILL AGREEMENT

     This Amended and Restated Standstill Agreement (the "Agreement") is 
entered into as of December 31, 1996, between Alliance Imaging, Inc., a 
Delaware corporation (the "Company"), and Richard N. Zehner (the "Holder").

                                    RECITALS

     A.   As of the date of this Agreement, the Company and the holders of 
the Company's issue of 7.50% Senior Subordinated Debentures due 2005 and 
Series A 6.0% Cumulative Preferred Stock (together, the "Securities") are 
completing transactions whereby the Securities are being repurchased by the 
Company for cash (the "Refinancing Transaction").

     B.   The Holder is the owner, as of the date hereof, of 267,139 shares 
(the "Restricted Shares") of Common Stock, $.01 par value per share (the 
"Stock"), which represent approximately 2.45% of the issued and outstanding 
Stock as of the date hereof.

     C.   The parties acknowledge and agree that the Company and its 
subsidiaries, as of the date hereof and after giving effect to previous 
restructuring transactions and the Refinancing Transaction, will have the 
right to certain valuable federal and state net operating loss tax 
carryforwards (collectively, the "NOL").

     D.   The parties desire to enter into this Agreement in order to set 
forth their agreement concerning certain restrictions on the purchase, sale 
or transfer of the Restricted Shares and other shares of Stock, in order to 
minimize the potential that a purchase, sale or transfer would result in a 
limitation on the use or otherwise affect adversely the value of the NOL.

     E.   Concurrently with the execution of this Agreement, the Company is 
offering to enter into those certain Amended and Restated Standstill 
Agreements with the previous holders of the Company's Senior Notes due 2003, 
the previous holders of the Securities and DLJ Capital Corporation (the 
"Other Standstill Agreements").  This Agreement amends, restates and 
supersedes in its entirety that certain Standstill Agreement between the 
Company and Holder dated as of December 31, 1994, and, to the extent that the 
parties to the Other Standstill Agreements elect to enter into their 
respective Amended and Restated Standstill Agreements, then such Amended and 
Restated Standstill Agreements shall likewise amend, restate and supersede in 
their entirety the preexisting Standstill Agreements between the Company and 
the applicable counterparties dated as of December 31, 1994 (the "Preexisting 
Standstill Agreements").

options, warrants or other rights to acquire Stock and/or securities

transfer shall not become effective earlier than ten (10) business days 
following the date that such written notice is delivered;

          (b)  the purchase of Stock pursuant to the exercise of options

not, without the consent of the Holder, amend any Other Standstill Agreement

expressly provides a period of time within which such right or remedy must be 
exercised and such period has expired, or unless such party has expressly 
waived the same in writing.  The waiver by a party of a right or remedy 
hereunder shall not be deemed to be a waiver of any other right or remedy or

Agreement shall be applicable only to the extent that they do not violate any 
applicable law, and are intended to be limited to the extent necessary so

expressly provides a period of time within which such right or remedy must be 
exercised and such period has expired, or unless such party has expressly 
waived the same in writing.  The waiver by a party of a right or remedy 
hereunder shall not be deemed to be a waiver of any other right or remedy or

or more counterparts, and by each party on a separate counterpart, each of

                                                       (DLJ CAPITAL CORPORATION)

                    AMENDED AND RESTATED STANDSTILL AGREEMENT

     This Amended and Restated Standstill Agreement (the "Agreement") is entered
into as of December 31, 1996, between Alliance Imaging, Inc., a Delaware
corporation (the "Company"), and DLJ Capital Corporation (the "Holder").

                                    RECITALS

     A.   As of the date of this Agreement, the Company and the holders of the
Company's issue of 7.50% Senior Subordinated Debentures due 2005 and Series A
6.0% Cumulative Preferred Stock (together, the "Securities") are completing
transactions whereby the Securities are being repurchased by the Company for
cash (the "Refinancing Transaction").

     B.   The Holder is the owner, as of the date hereof, of the number of
shares (including shares issuable upon the exercise of warrants currently held
by the Holder) (the "Restricted Shares") of Common Stock, $.01 par value per
share (the "Stock"), set forth beneath its name on the signature pages hereto.

     C.   The parties acknowledge and agree that the Company and its
subsidiaries, as of the date hereof and after giving effect to previous
restructuring transactions and the Refinancing Transaction, will have the right
to certain valuable federal and state net operating loss tax carryforwards
(collectively, the "NOL").

     D.   The parties desire to enter into this Agreement in order to set forth
their agreement concerning certain restrictions on the purchase, sale or
transfer of the Restricted Shares and other shares of Stock, in order to
minimize the potential that a purchase, sale or transfer would result in a
limitation on the use or otherwise affect adversely the value of the NOL.

     E.   Concurrently with the execution of this Agreement, the Company is
offering to enter into those certain Amended and Restated Standstill Agreements
with the previous holders of the Company's Senior Notes due 2003, the previous
holders of the Securities and Richard N. Zehner (the "Other Standstill
Agreements").  This Agreement amends, restates and supersedes in its entirety
that certain Standstill Agreement between the Company and the Holder dated as of
December 31, 1994, and, to the extent that the parties to the Other Standstill
Agreements elect to enter into their respective Amended and Restated Standstill
Agreements, then such Amended and Restated Standstill Agreements shall likewise
amend, restate and supersede in their entirety the preexisting Standstill
Agreements between the Company and the 

<PAGE>

applicable counterparties dated as of
December 31, 1994 (the "Preexisting Standstill Agreements").

     NOW, THEREFORE, in consideration of the foregoing and other good and
valuable consideration, receipt of which hereby is acknowledged, the parties
hereby agree as follows:

     1.   STANDSTILL PROVISIONS.  The Holder agrees that, at all times from and
after the date of this Agreement and through January 31, 1998, it shall not,
except as permitted in Section 2 hereof, take any of the following actions, and
it shall not cause its respective shareholders, officers, directors,
Subsidiaries and other Affiliates (as such terms are defined in Section 3 below)
to take any of the following actions in such Holder's name or on such Holder's
behalf, and shall cause its respective Subsidiaries and Affiliates not to, in
all instances whether directly or indirectly and whether alone, jointly or
collectively:

          (a)  acquire, agree to acquire, offer to acquire or own or otherwise
hold any Stock of the Company or any other Voting Stock (as defined below) of
the Company, excluding only the continued holding of the Restricted Shares; or 

          (b)  sell or otherwise transfer, agree to sell or otherwise transfer
or offer to sell or otherwise transfer any of the Restricted Shares or other
shares of Voting Stock.

     2.   PERMITTED TRANSFERS.  Notwithstanding the provisions of Section 1,
this Agreement does not prohibit the following: 

          (a)  a transfer of Restricted Shares by the Holder to any Person in
connection with (i) a sale of all or substantially all of the assets of the
Company and its subsidiaries to a Person which is not an Affiliate of the
Company or (ii) a reorganization, merger, consolidation or other transaction or
transactions (whether or not the Company is a party thereto and specifically
including, without limitation, open market purchases of securities) as a result
of which any person or entity or "group" of persons and/or entities becomes the
"beneficial owner" (as those terms are defined in and construed by judicial
authority under Rule 13d-3 promulgated under the Exchange Act, as that Rule may
be amended from time to time) of Stock and/or options, warrants or other rights
to acquire Stock and/or securities convertible into or exchangeable or
exercisable for Stock, representing in the aggregate greater than 50% of the
ordinary voting power of the Company in the election of directors (any such
event described in clauses (i) and (ii) of this Section 2 being a "Change of
Control"), provided that such transfer is effective no earlier than the
consummation date of such Change of Control; PROVIDED, HOWEVER, that prior to
such transfer becoming effective or any agreement or commitment for such
transfer being made or becoming effective, the Holder shall give written notice


                                       -2-

<PAGE>

to the Company, in order to provide the Company with the opportunity to analyze
the effects of the proposed transfer on the NOL and to discuss the same with the
Holder, and such proposed transfer shall not become effective earlier than ten
(10) business days following the date that such written notice is delivered; 

          (b)  the sale by the Holder of not more than one percent (1%) of such
Holder's Restricted Shares during any calendar month, beginning with January
1997; 

          (c)  the purchase of Stock by the Holder issuable upon exercise of
warrants currently held by the Holder; or

          (d)  (i) a transfer by the Holder or its Affiliates (which are
registered under the Exchange Act) of Stock (other than Restricted Shares) in
connection with its normal trading activities as a broker-dealer; (ii) a
transfer by the Holder or its Affiliates of Stock (other than Restricted Shares)
which are held by the Holder or its Affiliates for the account of any other
person or entity or in the name of a customer account; (iii) a transfer of Stock
(other than Restricted Shares) by the Holder or its Affiliates which are held in
an investment advisory account; (iv) a transfer of Stock (other than Restricted
Shares) by Donaldson, Lufkin & Jenrette Securities Corporation, as Custodian
under a Custody Agreement dated December 15, 1992; (iv) a transfer of Restricted
Shares or other Stock to any DLJ Entity.

Notwithstanding anything in the foregoing to the contrary, nothing herein shall
prohibit any transfer of Restricted Shares by the Holder to the Company.

          4.4  AMENDMENT OF OTHER STANDSTILL AGREEMENTS.  The Company will not,
without the consent of the Holder, amend any Other Standstill Agreement or
Preexisting Standstill Agreement, as applicable, such that any provision therein

favorable to the other party or parties thereto, unless the Company also offers
concurrently to amend this Agreement in a like manner.

of its rights or obligations hereunder.  Subject to the foregoing, this

right or remedy that it has under this Agreement unless this Agreement expressly
provides a period of time within which such right or remedy must be exercised
and such period has expired, or unless such party has expressly waived the same
in writing.  The waiver by a party of a right or remedy hereunder shall not be
deemed to be a waiver of any other right or remedy or of any subsequent right or
remedy of the same kind.

          4.9  COUNTERPARTS; NUMBER.  This Agreement may be executed in two or
more counterparts, and by each party on a separate counterpart, each of which
shall be deemed an original, but all of which taken together shall constitute

Capital Stock of the Borrower.  Except as provided in this Agreement, the 
Borrower is not a party or subject to any agreement or understanding, and, to 
the Borrower's Knowledge, there is no agreement or understanding between any 
persons and/or entities, that affects or relates to the voting or giving of 
written consents with respect to any of the Borrower's voting securities.

          4.3  SUBSIDIARIES.  SCHEDULE 4.3 sets forth a correct and complete 
list of:  (i) the name, number of shares, partnership interests or other 
equity interests held, and percentage ownership by the Borrower in each 
corporation, partnership, joint venture or other entity in which the Borrower 
has, directly or indirectly, any equity interest in the capital stock 
thereof, any partnership interest, or any other equity interest therein 
(individually a "SUBSIDIARY" and collectively "SUBSIDIARIES".)  Except as 
specifically set forth in SCHEDULE 4.3, the Borrower owns of record and 
beneficially all of the outstanding capital stock of each of the Subsidiaries 
free and clear of all Liens.  Each of the Subsidiaries is duly organized, 
validly existing and in good standing under the laws of its jurisdiction of 
incorporation, is entitled to own, lease or operate the properties and assets 
it now owns, leases or operates, and is qualified to do business, is in good

failure to obtain or maintain such qualification, good standing or licensing, 
or group of the foregoing, would have a Material Adverse Effect on such 
Subsidiary.  The shares of capital stock of each Subsidiary shown in SCHEDULE 
4.3 to be issued and outstanding have been validly authorized and issued and 
are validly outstanding, fully paid and non assessable.  No Subsidiary holds 
shares of its capital stock in its treasury, and there are not outstanding 
(i) any options, warrants or other rights with respect to the capital stock 
of any of the Subsidiaries, (ii) any securities convertible into or 
exchangeable for shares of such stock or (iii) any other commitments of any 
kind for the issuance of additional shares of capital stock or options, 
warrants or other securities of any of them.  The Borrower has provided or 
made available to the Lender copies of the certificates of incorporation, 
articles of incorporation, partnership agreements, limited liability company 
operating agreements, joint venture agreements, or other governing documents 
with respect to each Subsidiary.

          4.4  AUTHORIZATION.

          (a)  The Borrower has all corporate and other requisite authority 
to execute, deliver and carry out and perform its obligations under the terms 
of the Loan Documents and the other agreements referred to herein, and all of 
the transactions contemplated hereunder and thereunder, including the sale 
and issuance of the Securities.  The execution and delivery of the Loan 
Documents, and the consummation of the transactions contemplated hereby and 
thereby, have been duly authorized by all necessary action on the part of the 
Borrower and, except as set forth herein, no other approval is required for 
the performance by the Borrower of its obligations hereunder, or thereunder.  
The Loan Documents and the other agreements referred to herein have been, and 
at Closing will be, duly executed and delivered by the Borrower.

          (b)  The Loan Documents and the other agreements referred to 
herein, when executed and delivered by the Borrower, will constitute valid 
and binding obligations of the Borrower, enforceable against the Borrower in 
accordance with their respective terms.

          (c)  The Board of Directors of the Borrower, by a unanimous written 
consent, has in light of and subject to the terms and conditions set forth 
herein, (i) determined that the Loan Documents, the other agreements referred 
to herein, and the transactions contemplated hereby and thereby, taken 
together, are in the best interest of the Borrower and its shareholders and 
(ii) approved the Loan Documents, the other agreements referred to herein, 
and the transactions contemplated hereby and thereby.  All required notices 
to, and approvals and consents of, the Borrower's shareholders for the Loan 
Documents and the other agreements referred to herein, and the consummation 
of the transactions contemplated hereby and thereby, have been validly given 
and obtained.

          4.5  GOVERNMENTAL AND OTHER CONSENTS; NO VIOLATION.  No consent, 
approval, order or authorization of, or registration, qualification, 
designation, declaration or filing with, any Governmental Authority or any 
other Person is required on the part of the Borrower in connection with the 
Borrower's valid execution, delivery or performance

of the Loan Documents or the other agreements referred to herein.  The 
execution, delivery and performance by Borrower of each Loan Document to 
which it is party, and the consummation of the transactions contemplated 
thereby, do not and will not (a) violate any provision of the Borrower's 
Certificate of Incorporation or Bylaws as currently in effect, (b) conflict 
with, result in a breach of, or constitute (or, with the giving of notice or 
lapse of time or both, would constitute) a default under, or, except for 
consents that have been obtained and are in full force and effect, require 
the approval or consent of any Person pursuant to, any Contractual Obligation 
of Borrower, or (c) result in the creation or imposition of any Lien upon any 
asset of Borrower.

          4.6  LITIGATION.  There is no action, suit, claim, arbitration, 
litigation, legal, administrative or other proceeding, or investigation (by 
any Governmental Authority or otherwise) pending against or affecting the 
Borrower, any Subsidiary or the assets, products or business of any of them 
or, to the Knowledge of the Borrower, any reasonable basis therefor or threat 
thereof, other than disputes and claims arising in the ordinary course of the 
Borrower's business that could not in the aggregate have a Material Adverse 
Effect on the Borrower and its Subsidiaries.  Neither the Borrower nor any 
Subsidiary is a party or subject to the provisions of any order, writ, 
injunction, judgment or decree of any court or other Governmental Authority.  
There is no action, suit, claim, arbitration, litigation, legal, 
administrative or other proceeding, or investigation by the Borrower or any 
Subsidiary currently pending or that the Borrower or any Subsidiary currently 
intends to initiate.  There are no judicial or administrative actions, 
proceedings or investigations pending or, to the Borrower's Knowledge, 
threatened, against the Borrower, any Subsidiary or any of their respective 
businesses, assets or products that seek to enjoin, question the validity of, 
or rescind the transactions contemplated by this Agreement or any of the 
other agreements referred to herein or otherwise prevent the Borrower from 
complying with the terms and provisions of this Agreement or any of such 
other agreements.

with generally accepted accounting principles ("GAAP") applied on a

that the Financial Statements may not contain all footnotes required by GAAP) 
and fairly present the consolidated financial condition of the Borrower and 
the Subsidiaries and the consolidated results of operations as of such dates 
and for such periods indicated. Since September 30, 1996, there has not been 
any material adverse change to the financial condition of the Borrower or any 
Subsidiary as set forth in the Financial Statements.  There are no 
Liabilities required by GAAP to be disclosed in the Financial Statements that

or indemnitor of any indebtedness of any other Person.  The Borrower

                                                                        Page  20

          (c)  Since January 1, 1994, there has been no material disagreement

Liabilities.  Since January 1, 1996 no Current Customers of the business have 
canceled or terminated their Contracts, or notified the Borrower or any 
Subsidiary in writing or, to the Knowledge of the Borrower or any Subsidiary, 
orally, of their specific intent to cancel or terminate their contract, 
except any such cancellations, terminations or notifications that in the 
aggregate could not have a Material Adverse Effect (taking into account 
revenue generated from replacement customers) on the Borrower and its 
Subsidiaries.

          (b)  SCHEDULE 4.10(b) contains a correct and complete list of all

<PAGE>
                                                                        Page  21

agreements, contracts, indebtedness, liabilities and other obligations to 
which the Borrower or any Subsidiary is a party or by which it is bound that 
are material to the conduct and operations of its business and properties, 
which provide for payments to or by the Borrower or any Subsidiary in excess 
of $500,000 annually or $2,000,000 in the aggregate, which obligate the 
Borrower or any Subsidiary to share, license or develop any product or 
technology, or which involve transactions or proposed transactions between 
the Borrower and any Subsidiary on the one hand, and the officers, directors, 
Affiliates or any Affiliate of the Borrower or any Subsidiary, on the other

Contracts that are contracts with Current Customers.

          (c)  The Borrower and the Subsidiaries have in all material

obligations under, and are not in default (or to the Borrower's Knowledge, 
would by the lapse of time and/or the giving of notice or otherwise be in 
default) in respect of, any of the Material Contracts.  To the Borrower's 
Knowledge, each of the Material Contracts is in full force and effect and is 
a valid and enforceable obligation against the Borrower or a Subsidiary, as 
applicable, and the other party thereto, in accordance with its terms.

          4.11 ABSENCE OF CHANGES.  Since January 1, 1996, except as

Knowledge, incurred or suffered any other event or condition of any character 
that could reasonably be expected to result in a Material Adverse Effect on 
the Borrower or any Subsidiary.

          4.12 INTELLECTUAL PROPERTY..  The Borrower and each of the 
Subsidiaries owns or possesses adequate rights to use all material patents, 
patent applications, trademarks, service marks, trade names, trademark 
registrations, service mark registrations, copyrights, technology, software, 
trade secrets, know-how and licenses necessary for the conduct of their 
respective businesses and have no reason to believe that the conduct of their 
respective businesses will conflict with, and have not received any notice of 
any claim of conflict with, any such rights of others.

          4.13 COMPLIANCE WITH OTHER INSTRUMENTS.  Neither the Borrower nor 
any Subsidiary is in violation or default of any provisions of its Charter or

Neither the Borrower nor any Subsidiary is in violation or default of any 
instrument, judgment, order, writ, decree or oral or written contract or 
other agreement to which it is a party or by which it is bound, except with 
respect to any such defaults which could not have a Material Adverse Effect 
on the Borrower or the relevant Subsidiary, as the case may be.  The 
execution, delivery and performance of the Loan Documents and the other 
agreements referred to in this Agreement, and the consummation of the 
transactions contemplated hereby and thereby, will not result in any such 
violation or be in conflict with any provision of the Charter Documents or 
Applicable Law, or any instrument, judgment, order, writ, decree, contract or 
other agreement, and will not be an event that results in the creation of any 
Lien upon any assets of the Borrower or any Subsidiary or constitute a 
default under or give rise to any right of termination, cancellation or 
acceleration of, or to a loss of any benefit to which the Borrower or any 
Subsidiary is entitled, under any contract or any license, franchise, permit 
or similar authorization relating to the Borrower or any Subsidiary or by 
which its business or assets may be bound.

          4.14 COMPLIANCE WITH LAW; APPROVALS.

Medicare and Medicaid), environmental protection, fire, zoning and building

future will not, have a Material Adverse Effect on the Borrower or any 
Subsidiary.

          (b)  Neither the Borrower nor any Affiliate has received notice of 
any violation (or of any investigation, inspection, audit, or other 
proceeding by any Governmental Authority involving allegations of any 
violation ) of any Applicable Law, or is in material default with respect to 
any Applicable Law, and to the best Knowledge of the Borrower and all 
Affiliates, no investigation, inspection, audit, or other proceeding by any 
Governmental Authority involving allegations of violation of any Applicable 
Law is threatened or contemplated.

          (c)  Neither the Borrower nor any Affiliate has any Knowledge of 
any proposed change in any Applicable Law that would materially adversely 
affect the transactions contemplated by this Agreement or all or any material

professional employees or agents of each of the Borrower and its Affiliates 
have, all licenses, franchises, permits, authorizations, including

Borrower and its Affiliates and the occupancy and operation, for its present 
uses, of the real and personal property which each of the Borrower and its 
Affiliates owns or leases, except where the failure to have such Approvals

conducted, including all material tangible assets reflected in the Borrower's 
most recent balance sheet included in the Financial Statements and all 
material tangible assets purchased or otherwise acquired by the Borrower or

practice).  None of such material tangible assets is subject to any material 
Lien except for Permitted Encumbrances.

              4.16 PLANT, PROPERTY, AND EQUIPMENT.  To the Borrower's

with no material defects; are in good operating condition and repair 
(ordinary wear and tear excepted); and are adequate in all material respects

              4.17 ACCOUNTS AND NOTES RECEIVABLE.  Except to the extent of 
applicable reserves for doubtful accounts and contract reserves shown on the 
Borrower's most recent balance sheet included in the Financial Statements, 
all of the accounts, notes and other receivables owed to the Borrower or any 
Subsidiary as of the date hereof or thereafter acquired or arising prior to 
the Closing Date, constitute, and as of the Closing Date will constitute, 
valid and enforceable claims (subject, as to the enforcement of remedies, to 
applicable bankruptcy, reorganization, insolvency, moratorium and similar 
laws affecting creditors' rights, and, with respect to the remedy of specific 
performance, equitable doctrines applicable thereto) arising from bona fide 
transactions on the part of the Borrower and the Subsidiaries and, to the 
Borrower's Knowledge, bona fide transactions for parties other than the 
Borrower and the Subsidiary in the ordinary course, and there are no claims, 
refusals to pay or other rights of set-off against any thereof (other than 
ordinary course disputes that could not in the aggregate have a Material 
Adverse Effect on the Borrower and its Subsidiaries, taken as a whole).  None 
of such accounts is pledged to any third party.  The reserve for doubtful

Financial Statements is in accordance with GAAP.

Knowledge, all the Lease Agreements are in full force and effect and are 
valid and enforceable against the other parties thereto in accordance with 
their terms (subject, as to the enforcement of remedies, to applicable 
bankruptcy, reorganization, insolvency, moratorium and similar laws affecting 
creditors' rights, and, with respect to the remedy of specific performance, 
equitable doctrines applicable thereto).  Neither the Borrower nor any 
Subsidiary is in default under any of the Lease Agreements.  To the 
Borrower's Knowledge, no other Person party to the Lease Agreements is in 
default under any of the Lease Agreements.  There are no other agreements 
that concern any right, title or interest in or to the Leased Real Property 
or grant to a third party the right to occupy the premises used in the 
business, other than Permitted Liens.  The Closing will not affect the rights 
to the continued use and possession of the Leased Real Property on the terms

such property is now used in the business.

              (c)  LEASES OF REAL PROPERTY TO OTHERS.  To the Borrower's

proceeding with respect to any Leased Real Property, (iii) any proposal by a 
tax authority to change materially the assessed value or assessment rates of 
any Leased Real Property, or (iv) any other claim, suit, proceeding, order or 
demand of any Governmental Authority or any Persons that could have a 
material adverse impact on the value, right to develop, use or condition of 
any Leased Real Property.

              (e)  DISPUTES.  There is no currently pending material claim, 
dispute or controversy with respect to any of the Lease Agreements.  To the 
Borrower's Knowledge, no Person has raised any material claim, dispute or 
controversy with respect to any of the Lease Agreements since January 1, 1995.

for any such claim. No officer, director or employee of the Borrower or any 
ERISA Affiliate has committed a material breach of any responsibility or 
obligation imposed upon fiduciaries by Title I of ERISA with respect to any 
Employee Benefit Plan, with respect to which breach the Borrower is or could 
be directly or indirectly liable.

              (g)  Other than routine uncontested claims for benefits, there 
is no claim pending involving any Benefit Plan by any Person against such 
plan or the Borrower or any ERISA Affiliate, nor, to the knowledge of the

always been so qualified, and either has received a favorable determination 
letter with respect to such qualified status from the IRS or has filed a 
request for such a determination letter with the IRS within the remedial 
amendment period such that such determination of qualified status will apply 
from and after the effective date of any such Employee Benefit Plan.

              (j)  With respect to any Group Health Plans maintained by the 
Borrower or its ERISA Affiliates, whether or not for the benefit of the 
Borrower's employees, the Borrower and its ERISA Affiliates have complied in 
all material respects with the provisions of COBRA.  The Borrower is not 
obligated to provide health care benefits of any kind to its retired or 
former employees or their dependents pursuant to any agreement or 
understanding.

              (k)  Except pursuant to the provisions of COBRA, neither the 
Borrower nor any ERISA Affiliate maintains any Employee Benefit Plan that

expected to have any material Liability to any former employee or individual 
who provided services to the Borrower in a capacity other than as an employee 
in circumstances where such Liability arises or would arise under the express 
terms of a Benefit Plan.  No charges of employment or labor law violations 
exist or, to the Borrower's Knowledge, are threatened, before any

proceeding, hearing, study or investigation (1) under any Environmental Law, 
(2) based on or related to the manufacture, processing, distribution, use, 
treatment, storage, disposal, transport or handling, or the emission,

validity or amount thereof is being contested in good faith and by 
appropriate proceedings and so long as any reserves or other appropriate 
provisions as may be required by GAAP shall have been made therefor.

              5.3 MAINTENANCE OF PROPERTIES.  The Borrower shall maintain or 
cause to be maintained in good repair, working order and condition (ordinary

              5.5 EXPENSES.  Borrower shall immediately pay Lender upon 
demand all reasonable costs and expenses incurred by Lender in connection 
with:  (a) the preparation of this Agreement (and all Exhibits and Schedules 
thereto), the Senior Note, the Series D Certificate of Designation, and the 
Series E Certificate of Designation; PROVIDED, HOWEVER, that the Borrower's 
maximum responsibility therefore shall be $81,000; and (b) following a 
Default, the enforcement or satisfaction by Lender of any of Borrower's 
obligations under this Agreement or the Senior Note.

              5.6  CONVERSION STOCK.   The Borrower shall at all times keep 
available out of its authorized but unissued shares of Common Stock, for the 
purpose of effecting the conversion of the shares of Series D Preferred Stock 
and the shares of Series E Preferred Stock, such number of its duly 
authorized shares of Common Stock as shall be sufficient to effect the 
conversion of the shares of Series D Preferred Stock and Series E Preferred 
Stock from time to time outstanding.  If at any time the number of authorized 
but unissued shares of Common Stock shall not be sufficient to effect the 
conversion of the then outstanding shares of Series D Preferred Stock and 
Series E Preferred Stock, the Borrower shall forthwith take such corporate 
action as may be necessary to increase its authorized but unissued shares of 
Common Stock to such number of shares as shall be sufficient for such purpose.

              5.7  COMPLIANCE WITH NOTE PURCHASE AGREEMENT.  So long as any 
portion of the Obligations has not been indefeasibly satisfied in full, 
Borrower shall comply in all respects with the terms of the Note Purchase 
Agreement dated as of April 14, 1989, as amended to the date hereof (the 
"NOTE PURCHASE AGREEMENT"). Without limiting the foregoing, the Borrower 
shall comply with all affirmative and negative covenants contained in the 
Note Purchase Agreement.

              5.8  CERTAIN REGULATORY MATTERS.    

              (a)  The operations of the Borrower and its Affiliates will be

limitation, all such laws, regulations, orders and requirements promulgated 
by or relating to consumer protection, equal opportunity, health, third party 
reimbursement (including Medicare and Medicaid), environmental protection, 
fire, zoning and building and occupational safety matters, except for 
violations that individually or in the aggregate would not and, insofar as 
may reasonably be foreseen, in the future will not, have a Material Adverse 
Effect on the Borrower or any Subsidiary.

              (b)  Without limiting the generality of the foregoing, the 
Borrower and all Affiliates shall comply in all material respects with all 
directives, orders, instructions, bulletins and other announcements received

in a bulletin from Blue Shield of California ("BSC") limiting reimbursement 
of the services of independent physiological laboratories to Medicare 
beneficiaries in BSC's region to cardiovascular studies, diagnostic 
ultrasound studies, and non-invasive vascular studies, all conducted 
according to the common procedural terminology ("CPT") codes listed in the 
most recent version of the CPT codebook for such studies, and shall refrain 
from submitting claims for Medicare reimbursement for MRI or CT studies to 
BSC until and unless written approval to submit such claims is received from 
the medical director of BSC, unless the Borrower or any Affiliate identifies 
an alternative proper resolution of such matter that is acceptable to the 
Lender, in its sole discretion.  Nothing in this Section 5.8 shall be 
construed as or is intended to create any third party beneficiaries.

              6.1 DEFAULT.  The occurrence of any one or more of the 
following shall constitute an event of default (hereinafter, "DEFAULT") under 
this Agreement and the other Loan Documents:

              (a)  Borrower (i) shall fail to pay as and when due any 
         scheduled installment of principal due hereunder or under the 
         Senior Note; or (ii) shall fail to pay within one day after the 
         due date thereof any interest, any fees or any other amount

         or covenant in any Section of Article V, including without

         Purchase Agreement in Section 5.7 (provided, however, that with 
         respect to the covenants incorporated by reference in Section 5.7, 
         no Default shall be deemed to have occurred until the expiration 
         of any grace or cure period provided for in the Note Purchase 
         Agreement with respect to such covenant); or
         
              (c)  Borrower shall fail to perform any other obligation 
         under any of the Loan Documents (other than those referred to in 
         Sections 6.1(a) and 6.1(b) above) for a period of thirty (30) days 
         after receipt of written notice of such failure (or, if delivery 
         of such notice is stayed or prohibited by applicable law, for a 
         period of thirty (30) days after such failure to perform); or
         
              (d)  the failure of any representation or warranty of 
         Borrower in any of the Loan Documents to be true on each date made 
         or deemed made; or
         
              (e)  (i) the filing of a petition by Borrower for relief 
         under the Bankruptcy Code, or under any other present or future 
         state or federal law regarding bankruptcy, reorganization or other 
         debtor relief law; (ii) the filing of any pleading or an answer by 
         Borrower in any involuntary proceeding under the Bankruptcy Code 
         or other debtor relief law which admits the jurisdiction of the 
         court or the petition's material allegations regarding Borrower's 
         insolvency; (iii) a general assignment by Borrower for the benefit 
         of creditors; or (iv) Borrower applying for, 

<PAGE>
                                                                       Page 37
         
         or the appointment of, a receiver, trustee, custodian or liquidator 
         of Borrower or any of its assets; or
         
              (f)  the failure of Borrower to effect a full dismissal of 
         any involuntary petition under the Bankruptcy Code or under any 
         other debtor relief law that is filed against Borrower or in any 
         way restrains or limits Borrower or Lender regarding the Loan 
         prior to the earlier of (i) the entry of any court order granting 
         relief sought in such involuntary petition or (ii) thirty (30) 
         days after the date of filing of such involuntary petition; 
         
              (g)  there shall occur any default or event of default under 
         the Note Purchase Agreement; or

     (h)  there shall occur any Change in Control.

              6.2  ACCELERATION UPON DEFAULT.  Upon the occurrence and during 
the continuance of a Default specified in Section 6.1(e) or (f), all sums 
owing to Lender under the Loan Documents immediately shall be due and 
payable.  Upon the occurrence and during the continuance of any Default 
specified in this Article VII (other than those referred to in the 
immediately preceding sentence), Lender may, at its sole option, declare all 
sums owing to Lender under the Loan Documents immediately due and payable.  

              6.3  REPAYMENT OF FUNDS ADVANCED.  Any funds expended by Lender 
in the exercise of its rights or remedies under this Agreement and the other 
Loan Documents shall be payable to Lender upon demand, together with interest 
at the rate applicable to the principal balance of the Senior Note from the 
date the funds were expended.  

              6.4  RIGHTS CUMULATIVE, NO WAIVER.  All Lender's rights and 
remedies provided in this Agreement and the other Loan Documents, together 
with those granted by law or at equity, are cumulative and may be exercised 
by Lender at any time.  Lender's exercise of any right or remedy shall not 
constitute a cure of any Default unless all sums then due and payable to 
Lender under the Loan Documents are repaid and Borrower has cured all other 
Defaults.  No waiver shall be implied from any failure of Lender to take, or 
any delay by Lender in taking, action concerning any Default or failure of 
condition under the Loan Documents, or from any previous waiver of any 
similar or unrelated Default or failure of condition.  Any waiver or approval 
under any of the Loan Documents must be in writing and shall be limited to 
its specific terms.

            ARTICLE VII.  LENDER'S OPTION TO EXTEND MATURITY DATE; 
                       OPTIONAL CONVERSION OF SENIOR LOAN

              7.1 LENDER'S OPTION TO EXTEND MATURITY DATE.  At any time prior 
to the original Maturity Date, Lender shall have the option to extend the 
Maturity Date to March 31, 1997.  If Lender determines, in its sole 
discretion, to extend the Maturity Date to March 31, 1997, Lender shall 
deliver written notice of such election to Borrower no later than ten (10) 
Business Days prior to the original Maturity Date.  Upon delivery of such 


<PAGE>
                                                                       Page 38


notice, the Maturity Date for all purposes under this Agreement (including 
without limitation, with respect to Sections 7.2, 7.3, 7.4, and 7.5) shall be 
deemed to be March 31, 1997.

              7.2 CONVERSION OF SENIOR LOAN PRIOR TO MATURITY DATE.  At any 
time at or prior to the Maturity Date, Lender shall have the option, in its 
sole discretion, to convert the Senior Loan into shares of Series D Preferred 
Stock, and to enter into certain transactions with Borrower related thereto, 
as further provided in this Section 7.2.  

              (a)  If Lender determines, in its sole discretion, to convert 
the Senior Loan into shares of Series D Preferred Stock, and to enter into 
the other Conversion Transactions (as defined below), Lender shall deliver 
written notice of such election to Borrower no later than two (2) Business 
Days prior to the Maturity Date in substantially the form set forth as 
EXHIBIT F hereto (the "CONVERSION NOTICE"); PROVIDED, HOWEVER, that a 
Conversion Notice delivered after February 26, 1997 will not be effective if 
the Maturity Date is extended to March 31, 1997 solely as a result of the 
Lender's not delivering the Conversion Notice prior to the original Maturity 
Date (rather than the Lender's exercise of its extension election under 
Section 7.1 above).  The Conversion Notice shall set forth the effective date 
of the Conversion Transactions (as defined below) (the "CONVERSION DATE"), 
which date shall not be earlier than five (5) nor later than ten (10) 
Business Days following the date of the Conversion Notice.

              (b)  If Lender timely delivers the Conversion Notice to 
Borrower, then Lender and Borrower shall consummate the following 
transactions (collectively, the "CONVERSION TRANSACTIONS") as soon as 
practicable after the date of the Conversion Notice, but in any event no 
later than the Conversion Date:

                   (i)  Lender and Borrower shall enter into a Series D 
     Preferred Stock Purchase Agreement substantially in the form 
     attached hereto as EXHIBIT G (with all Exhibits and Schedules 
     thereto, and all documents to be delivered thereunder (including 
     without limitation any legal opinions), to be satisfactory to 
     Lender, in its sole discretion), and Lender and Borrower shall 
     consummate the transactions contemplated thereby;

                   (ii)  Borrower shall pay to Lender on the Conversion 
     Date all accrued interest on the Senior Loan in cash (including 
     without limitation any interest accrued at the Default Rate);
     
                  (iii)  Borrower and Lender shall enter into an Eleventh 
     Amendment to the Note Purchase Agreement, substantially in the form 
     attached hereto as EXHIBIT H, and Lender and Borrower shall 
     consummate the transactions contemplated thereby.
     
              (c)  If Lender does not timely deliver the Conversion Notice to 
Borrower pursuant to this Section 7.2, then the Maturity Date shall be 
extended automatically to March 31, 1997, and the Maturity Date for all 
purposes under this Agreement (including without limitation, with respect to 
Sections 7.2, 7.3, 7.4, and 7.5) shall be deemed to be March 31, 1997.

              7.3  CONVERSION OF SENIOR LOAN AFTER MATURITY DATE.  If for any 
reason all or part of the Senior Loan is still outstanding after the Maturity 
Date, then Lender shall have the option, in its sole discretion, to convert 
the Senior Loan into shares of Series D Preferred Stock, and to enter into 
the other Conversion Transactions, as further provided in this Section 7.3.

              (a)  If Lender determines, in its sole discretion, to convert 
the Senior Loan into shares of Series D Preferred Stock, and to enter into 
the other Conversion Transactions, after the Maturity Date, Lender may 
deliver a Conversion Notice at any such time to Borrower.  The Conversion 
Notice shall set forth the Conversion Date.

              (b)  After delivery of the Conversion Notice to Borrower, 
Lender and Borrower shall consummate the Conversion Transactions as soon as 
practicable after the date of the Conversion Notice, but in any event no 
later than the Conversion Date.  

              7.4 ACKNOWLEDGEMENT.  Lender and Borrower acknowledge and agree 
that Lender shall under no circumstances be under any obligation to exercise 
its right to elect to enter into the Conversion Transactions contemplated by 
this Article 7,  that notwithstanding the provisions of this Article 7, if 
Lender does not deliver the Conversion Notice, Lender shall have the absolute 
right at and at any time after the Maturity Date to repayment of the Senior 
Loan and all other amounts due and payable to Lender from Borrower under the 
Loan Documents.

                   ARTICLE VIII.  MISCELLANEOUS PROVISIONS

              8.1  INDEMNITY.  Borrower hereby agrees to defend, indemnify 
and hold harmless Lender, and its directors, officers, employees, agents, 
successors and assigns from and against any and all losses, damages, 
liabilities, claims, actions, judgments, costs and reasonable legal or other 
expenses (including, without limitation, reasonable attorneys' fees and 
expenses) ("CLAIMS") such indemnified party may incur as a direct or indirect 
consequence of:  (a) the transactions contemplated hereby; (b) the purpose to 
which Borrower applies the proceeds of the Loan; (c) the failure of Borrower 
to perform any obligations as and when required by this Agreement or any of 
the other Loan Documents; or (d) any failure at any time of any of Borrower's 
representations or warranties to be true and correct.  Borrower shall 
immediately pay to Lender upon demand any amounts owing under this indemnity, 
together with interest from the date the indebtedness arises until paid at 
the rate of interest applicable to the principal balance of the Senior Note.  
BORROWER'S DUTY TO INDEMNIFY LENDER HEREUNDER SHALL SURVIVE THE REPAYMENT OF 
THE LOAN.

              8.2  NOTICES.  All notices, demands, or other communications 
under this Agreement and the other Loan Documents shall be in writing and 
shall be delivered via confirmed facsimile, overnight courier, by hand 
delivery or by certified mail, return receipt requested, to the appropriate

three (3) days after the deposit in the United States Postal Service mail, 
postage prepaid and addressed to the address of Borrower or Lender at the 
address specified or, if transmitted via facsimile, upon electronic 
confirmation of receipt; PROVIDED, HOWEVER, that non-receipt of any 
communication as the result of any change of address or facsimile number of 
which the sending party was not notified or as the result of a refusal to 
accept delivery shall be deemed receipt of such communication.

              8.3  ATTORNEYS' FEES AND EXPENSES; ENFORCEMENT.  If any 
attorney is engaged by Lender to interpret, administer, enforce or defend any 
provision of this Agreement or any of the other Loan Documents, or as a 
consequence of any Default under the Loan Documents, with or without the 
filing of any legal action or proceeding, Borrower shall immediately pay to 
Lender, upon demand, the amount of all reasonable attorneys' fees and 
expenses and all costs incurred by Lender in connection therewith, together 
with interest thereon from the date of such demand until paid at the rate of 
interest applicable to the principal balance of the Senior Note as specified 
therein. 

              8.4  IMMEDIATELY AVAILABLE FUNDS.  Unless otherwise expressly 
provided for in this Agreement, all amounts payable by Borrower to Lender 
shall be payable only in United States currency, immediately available funds.

              8.5  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding 
upon and inure to the benefit of the parties hereto and their respective 
successors and permitted assigns.  Borrower may not assign or transfer any 
interest hereunder without the prior written consent of Lender.

              8.6  PARTICIPATIONS.  Lender may, at any time, sell, assign or 
grant participations in all or any portion of its rights and obligations 
under the Loan Documents to one or more Affiliates of Lender, with Borrower's 
consent and approval (which consent and approval will not be unreasonably 
withheld, conditioned or delayed).  Borrower further agrees that, in 
connection with any such sale, assignment or participation, Lender may 
disseminate to any such actual or potential servicer(s), purchaser(s), 
assignee(s) or participant(s) all documents and information (including, 
without limitation, all financial information) which has been or is hereafter 
provided to or known to Lender with respect to:  (a) any Property and its 
operation; (b) any party connected with the Loan (including, without 
limitation, Borrower; and/or (c) any relationship other than the Loan which 
Lender may have with any party connected with the Loan.  Borrower shall 
supply to Lender all reasonably requested information and execute and deliver 
all such instruments and take all such further action Lender may reasonably 
request in connection with any such sale, assignment or participation.  In 
the event of any such sale, assignment or participation, Lender and the 
parties to such transaction shall share in the rights and obligations of 
Lender as set forth in the Loan Documents only as and to the extent they 
agree among themselves.  In connection with any such sale, assignment or 
participation, Borrower further agrees that the Loan Documents shall be 
sufficient evidence of the obligations of Borrower to each purchaser, 
assignee, or participant, and upon written request by Lender, Borrower shall 
enter into such amendments or modifications to the Loan Documents as may be 

<PAGE>
                                                                       Page 41


reasonably required in order to evidence any such sale, assignment or 
participation.  The indemnity obligations of Borrower under the Loan 
Documents shall also apply with respect to any purchaser, assignee or 
participant.

              8.7 SEVERABILITY.  If any provision or obligation under this 
Agreement and the other Loan Documents shall be determined by a court of 
competent jurisdiction to be invalid, illegal or unenforceable, that 
provision shall be deemed severed from the Loan Documents and the validity, 
legality and enforceability of the remaining provisions or obligations shall 
remain in full force as though the invalid, illegal, or unenforceable 
provision had never been a part of the Loan Documents, PROVIDED, HOWEVER, 
that if the rate of interest or any other amount payable under the Senior 
Note or this Agreement or any other Loan Document, or the right of 
collectability therefore, are declared to be or become invalid, illegal or 
unenforceable, Lender's obligations to make advances under the Loan Documents 
shall not be enforceable by Borrower.

              8.8  NO WAIVER; SUCCESSORS.  No waiver shall be implied from 
any failure of Lender to take, or any delay by Lender in taking, action 
concerning any Default or failure of condition, or from any previous waiver 
of any similar or unrelated Default or failure of condition.  Any waiver or 
approval hereunder must be in writing and shall be limited to its specific 
terms.  No amendment of any provision of this Agreement or any other Loan 
Document (including a waiver thereof or consent relating thereto) shall be 
effective unless the same shall be in writing and signed by Borrower and 
Lender.

              8.9  TIME.  Time is of the essence of each and every term of 
this Agreement.

              8.10  HEADINGS.  All article, section or other headings 
appearing in this Agreement and any of the other Loan Documents are for 
convenience of reference only and shall be disregarded in construing this 
Agreement and any of the other Loan Documents.

              8.11  GOVERNING LAW.  This Agreement shall be governed by, and 
construed and enforced in accordance with the laws of the State of New York.  
Borrower and all persons and entities in any manner obligated to Lender under 
the Loan Documents consent to the jurisdiction of any Federal or State Court 
within the State of New York and also consent to service of process by any 
means authorized by New York or Federal Law.

              8.12  INTEGRATION; INTERPRETATION.  The Loan Documents contain 
or expressly incorporate by reference the entire agreement of the parties 
with respect to the matters contemplated therein and supersede all prior 
negotiations or agreements, written or oral.  Any reference to the Loan 
Documents includes any amendments, renewals or extensions now or hereafter 
approved by Lender in writing.

              8.13  WAIVER OF ALLOCATION RIGHTS.  Borrower hereby irrevocably 
waives, disclaims and renounces any right to designate the portion of the 
Obligations satisfied, or deemed to be satisfied, upon payment of any of the 
Obligations by any guarantor or surety of all or any portion of the 
Obligations, it being the understanding and agreement 

<PAGE>
                                                                       Page 42


of Borrower, Lender and any such guarantor or surety that Lender may allocate 
any and all payments on the Obligations so as to maximize Lender's recovery 
against Borrower and all guarantors or sureties.

              8.14  USURY SAVINGS.  It is the intention of the parties hereto 
to conform strictly to the usury and other laws relating to interest from 
time to time in force, and all agreements between Borrower and Lender, 
whether now existing or hereafter arising and whether oral or written, are 
hereby expressly limited so that in no contingency or event whatsoever, 
whether by acceleration or maturity or otherwise, shall the amount paid or 
agreed to be paid to Lender, or collected by Lender for the use, forbearance 
or detention of the money to be loaned under the Senior Note, this Agreement 
or otherwise, or for the payment or performance of any covenant or obligation 
contained herein or in any of the other Loan Documents or in any other 
security agreement given to secure the Loan or in any other document 
evidencing, securing or pertaining to the Loan, exceed the maximum amount of 
interest allowable under applicable law (the "MAXIMUM AMOUNT").  If under any 
circumstances whatsoever fulfillment of any provision hereof or any other 
Loan Document, at the time performance of such provision shall be due, shall 
involve transcending the Maximum Amount, then IPSO FACTO, the obligation to 
be fulfilled shall be reduced to the Maximum Amount.  For the purposes of 
calculating the actual amount of interest paid and or payable, in respect of 
laws pertaining to usury or such other laws, all sums paid or agreed to be 
paid to the holder of the Senior Note for the use, forbearance or detention 
of the Loan shall, to the extent permitted by applicable law, be amortized, 
allocated and spread from the date of disbursement of the proceeds of the 
Loan until payment in full of the Loan, so that the actual rate of interest 
on account of the Loan is uniform throughout the term hereof.  If under any 
circumstances Lender shall ever receive an amount deemed interest by 
applicable law, which would exceed the Maximum Amount, such amount that would 
be excessive interest under applicable usury laws shall be deemed a payment 
in reduction of the principal amount owing under the Senior Note and shall be 
so applied to principal and not to the payment of interest, or if such 
excessive interest exceeds the outstanding principal balance of the Loan, 
such excessive interest shall be deemed to have been a payment made by 
mistake and shall be refunded to Borrower or to any other person making such 
payment on Borrower's behalf.

              8.15  REVIVAL.  To the extent Borrower makes a payment to 
Lender, which payment or the proceeds or any part thereof are subsequently 
invalidated, declared to be fraudulent or preferential, set aside or required 
to be repaid to a trustee, receiver or any other party having requisite 
authority under the Bankruptcy Code or any bankruptcy law, state or federal 
law, common law or equitable cause, then, to the extent of such payment or 
proceeds received, the obligation hereunder or part thereof intended to be 
satisfied shall be revived and continue in full force and effect, as if such 
payment or proceeds had not been received.<PAGE>

              8.16  COUNTERPARTS.  This Agreement, any of the other Loan 
Documents (except for the Senior Note), and any subsequent modifications, 
amendments, waivers, consents or supplements thereof, if any, may be executed 
in any number of counterparts, each of which when executed and delivered 
shall be deemed to be an original and all such counterparts together, shall

                                                               December 31, 1996

FOR VALUE RECEIVED, the undersigned, Alliance Imaging, Inc., a Delaware
corporation ("BORROWER"), promises to pay to the order of General Electric
Company, a New York corporation or its assigns ("LENDER"), in New York, New
York, or at such other place as may be designated in writing by the holder of
this Senior Bridge Note (together with all supplements, amendments or
modifications hereto or renewals hereof, the "NOTE"), on February 28, 1997 (the
"Maturity Date"), the principal sum of Eighteen Million Dollars
($18,000,000.00), with interest (computed on the basis of a 360-day year of
twelve 30-day months) on the unpaid principal hereof at the rate of 10% per
annum from December 31, 1996, payable on the Maturity Date, and thereafter to
pay interest (so computed) at the rate of 14% per annum on any overdue principal
and, to the extent permitted by applicable law, on any overdue interest, until
the same shall be paid.  All sums owing hereunder are payable in lawful money of
the United States of America, in immediately available funds.  The loan
evidenced hereby (the "LOAN") has been extended by Lender to Borrower pursuant
to the Bridge Loan Agreement between Borrower and Lender dated as of December
31, 1996 (the "LOAN AGREEMENT").  All of the terms, covenants and conditions of
the Loan Agreement and all other instruments evidencing the indebtedness
hereunder are hereby made a part of this Note and are deemed incorporated herein
in full.  In particular, but without limitation of the foregoing, the Maturity
Date is subject to extension in the circumstances described in the Loan
Agreement.

Notwithstanding the previous paragraph, at any time after the occurrence and
during the continuation of a Default, interest shall accrue on this Note at the
rate of 14% per annum.

1.   PRINCIPAL PAYMENTS.  The principal amount of the indebtedness from time to
     time evidenced hereby shall be payable in the amounts and on the dates
     specified in the Loan Agreement and, if not sooner paid in full, the
     outstanding principal balance of this Note, together with all accrued and
     unpaid interest, shall be due and payable in full on the Maturity Date.

2.   PREPAYMENT.  Borrower shall not have the right to prepay the Loan.

3.   LENDER'S OPTION TO ACCELERATE.  If:  (a) Borrower shall fail to pay when
     due any sums payable hereunder; OR (b) a Default occurs, THEN Lender may,
     at its sole option, declare all sums owing under this Note immediately due
     and payable.

4.   LENDER'S OPTION TO CONVERT.  Lender may, at its sole option, convert
     principal amounts owing under this Note to shares of the Borrower's Series
     D 4% Cumulative Redeemable Convertible Preferred Stock, on the terms and as
     set forth in the Loan Agreement.

5.   ATTORNEYS' FEES.  If any attorney is engaged by Lender to enforce or defend
     any provision of this Note or the Loan Agreement, or as a consequence of
     any Default, with or without the filing of any legal action or proceeding,
     then Borrower shall pay to Lender immediately upon demand all attorneys'
     fees and all costs incurred by Lender in connection therewith, together
     with interest thereon from the date of such demand until paid at the rate
     of interest applicable to the principal balance owing hereunder as if such
     unpaid attorneys' fees and costs had been added to the principal.

6.   NO WAIVER.  No previous waiver and no failure or delay by Lender in acting
     with respect to the terms of this Note or any Loan Document shall
     constitute a waiver of any breach, default, or failure of condition under
     this Note, such Loan Document or the obligations secured thereby.  A waiver
     of any term of this Note, any Loan Document or of any of the obligations
     secured thereby must be made in writing and shall be limited to the express
     written terms of such waiver.  In the event of any inconsistencies between
     the terms of this Note and the terms of any other document related to the
     Loans, the terms of this Note shall prevail.

7.   BORROWER WAIVERS.  Except as otherwise provided in any agreement executed
     in connection with this Note, Borrower waives: presentment; demand; notice
     of dishonor; notice of default or delinquency; notice of acceleration;
     notice of protest and nonpayment; notice of costs, expenses or losses and
     interest thereon; notice of late charges; and diligence in taking any
     action to collect any sums owing under this Note.

8.   TIME OF THE ESSENCE.  Time is of the essence with respect to every
     provision hereof.

9.   GOVERNING LAW.  This Note is made and delivered in New York, New York, and
     shall be governed by the laws of the State of New York.

                                   ASSIGNMENT


     THIS ASSIGNMENT (the "Assignment") is made this 31th day of December, 1996
by the holders listed on the signature page hereto (each a "Holder" and together
the "Holders"), with reference to the 7.50% Senior Subordinated Debentures due
2005 (the "Debentures") and the Series A 6.0% Cumulative Preferred Stock (the
"Preferred Stock"; collectively, the Debentures and the Preferred Stock are
referred to as the "Securities") of Alliance Imaging, Inc. (the "Company") held
by the Holders, and issued pursuant to an Amended and Restated Purchase
Agreement dated as of December 31, 1994, as amended by that certain First
Amendment to Amended and Restated Purchase Agreement dated as of December 31,
1994, as amended by that certain Second Amendment to Amended and Restated

Agreement"), to the Company. 

     NOW, THEREFORE, in consideration of the payment hereinafter provided, the
undersigned does hereby agree as follows:

     1.   REPURCHASE OF SECURITIES.  Each of the Holders, severally and not
jointly, does hereby sell and transfer to the Company all of its right, title
and interest in and to all of such Holder's (i) Debentures (including principal,
accrued and unpaid interest thereon through the date hereof and any and all
other obligations of the Company under such Debentures) and (ii) Preferred Stock
(including, with respect to each share of Preferred Stock, the face amount
thereon, accumulated and unpaid dividends through the date hereof and any and
all other obligations of the Company under such Preferred Stock).  Said sales
and transfers (the "Repurchase Transaction") are being made in consideration of
the payment in cash to the Holder of the amount set forth opposite its
respective name on Schedule 1 hereto (the "Purchase Price"), which amount is
being paid by the Company to the respective Holder simultaneously with the
execution and delivery of this Assignment.  In the case of each Holder, that
portion of the Purchase Price equal to the principal amount of the Debentures
and all accrued and unpaid interest thereon through the date hereof is being
paid in consideration of the Debentures and the other rights described in clause
(i) above, and the balance of the Purchase Price is being paid in consideration
of the Preferred Stock and the other rights described in clause (ii) above. 
Payments are being made by wire transfer of immediately available federal funds
to accounts specified by the respective Holders prior to the date hereof, or by
bank cashiers check, as previously specified by such Holder.  Each Holder,
severally and not jointly, is hereby delivering or causing to be delivered to
the Company all of such Holder's certificates representing such Holder's
Debentures and Preferred Stock, in each case duly endorsed for transfer or
accompanied by duly executed instruments of transfer separate from certificates.

<PAGE>

     Upon the closing of the Repurchase Transaction, all of the Company's
obligations and indebtedness to each Holder under the Purchase Agreement, the
Debentures and the Preferred Stock, and the obligations of the Company's
subsidiaries under the Guaranty (as defined in the Purchase Agreement), shall be
deemed fully satisfied and repaid, and such instruments and agreements shall be
of no further force or effect.

     2.   REPRESENTATIONS AND WARRANTIES.  Each Holder, severally and not
jointly, does hereby represent and warrant to the Company as follows:

          2.1  DUE AUTHORIZATION, NO CONFLICT, ETC.  The Holder has all
requisite power and authority to enter into this Assignment and to transfer the
Securities and to perform each other provision hereof.  The execution, delivery

against it in accordance with its terms.  None of the execution, delivery and
performance of this Assignment conflicts with the charter documents of the
Holder or any law or regulation applicable to the Holder, and none of the

or notice to any governmental authority, other than any such consent or notice
that has been obtained or given.

          2.2  SECURITIES.  The Holder is the registered and beneficial owner of
the Securities in the aggregate outstanding principal or, as the case may be,
face amount as set forth opposite its name on Schedule 2 hereto.  The Holder has
not heretofore sold or otherwise transferred any right, title or interest in or
to any of the Securities, and the Securities being sold and transferred to the
Company hereby are free and clear of any and all liens, claims, security
interests and encumbrances whatsoever.  To the knowledge of the Holder, no
action or suit by any party is pending or threatened concerning ownership of or
compliance with the terms of the Securities.  Upon payment of the purchase price
by the Company pursuant to this Assignment, the Company will be the legal and
beneficial owner of all of the Securities, free and clear of all liens, claims,

Subsidiary is in default under any of the Lease Agreements.  To the Company's

any of the Lease Agreements.  There are no other agreements that concern any 
right, title or interest in or to the Leased Real Property or grant to a 
third party the right to occupy the premises used in the business, other than

full and there is outstanding no Indebtedness incurred to finance such 
purchase price, it being understood that the cross-collateralization 
permitted by the immediately preceding proviso shall immediately cease and 
terminate as to any Unit upon payment of the purchase price (or related 
purchase money Indebtedness) of such Unit; and (ii) in the case of 
newly-acquired Financed Equipment, any such Lien shall be created within six 
(6) months after the acquisition thereof;

                         (f)  Liens on property or assets of any 
Majority-Owned Subsidiary to secure Debt For Money Borrowed of a 
Majority-Owned Subsidiary to the Company or to another Majority-Owned 
Subsidiary in existence on the Seventh Amendment Effective Date;

                         (g)  Liens securing Indebtedness of the Company and 
its Majority-Owned Subsidiaries existing on the Seventh Amendment Effective 
Date;

Majority-Owned Subsidiary to secure Indebtedness permitted by Section 8.9(f)
hereof;

                         (i)  Subject to the limitations set forth in Section 
8.9(d) hereof, any Lien created to secure any Indebtedness incurred or 
assumed after the Seventh Amendment Effective Date to pay all or any part of 
the purchase price of an improvement to or upgrade of a Unit owned by the 
Company or a Majority-Owned Subsidiary, PROVIDED that (i) any such Lien shall 
be confined solely to the improved or upgraded Unit subject to such Lien; 
PROVIDED, HOWEVER, that in the case of a Unit owned by the Company or a 
Majority-Owned Subsidiary that is, at the time of acquisition of an 
improvement or upgrade to a Unit, already subject to a Lien in favor of the 
same secured party financing the purchase price of such improvement or 
upgrade, such Lien securing the Indebtedness relating to the newly-improved 
or upgraded Unit may extend to the Unit already owned and such Lien securing 
the Indebtedness relating to the Unit already owned may extend to the 
newly-improved Unit; PROVIDED, FURTHER, that notwithstanding the immediately 
preceding proviso no such Lien shall extend to any Unit as to which (A) the 
purchase price thereof (and of any improvement thereto or upgrade thereof) is 
paid in full and (B) there is outstanding no Indebtedness incurred to finance 
such purchase price, it being understood that the cross-collateralization 
permitted by the immediately preceding proviso shall immediately cease and 
terminate upon payment of the purchase price (or related purchase money 
Indebtedness) of each Unit and any improvement to or upgrade thereof, and 
(ii) any such Lien shall be created within six months after the completion or 
installation of such improvement or upgrade;

                         (j)  Any Lien created to secure Indebtedness incurred 
to finance equipment pursuant to the terms of Section 8.9(d) hereof; and

                         (k)  Any extension, renewal or replacement (or 
successive extensions, renewals or replacements), in whole or in part, of (a) 
through (j) above, so long as the outstanding principal amount of the 
Indebtedness secured by such Lien at the time of such extension, renewal or 
replacement is not increased, nor the periodic debt service payment 
(principal and interest) payable with respect thereto increased, and the 
renewed or extended-Lien does not cover any property which is not covered by 
the existing Lien renewed or extended thereby.

                    8.9. INDEBTEDNESS.  The Company covenants and agrees that 
so long as, and at any time that, (i) any shares of Preferred Stock are held 
by the Investor or any Eligible Holder, and (ii) the IRR Trigger Date has not 
occurred, the Company will not create, incur or assume or permit to exist, 
and will not permit any Majority-Owned Subsidiary to create, incur or assume 
or permit to exist or remain liable with respect to Indebtedness, other than 
the following:

                         (a)  The Company may become and remain liable with 
respect to Indebtedness for working capital purposes under the Working 
Capital Facility as provided for in Section 9.06 of the Note Purchase 
Agreement or any renewal, extension or replacement thereof, provided that the 
indebtedness thereunder does not at any time exceed 75% of the net accounts 
receivable of the Company (determined in accordance with GAAP) and the terms 
and conditions thereof are not, in the aggregate,

                                                                        Page 49


materially more burdensome than under the preexisting Working Capital 
Facility and reflect current market conditions;

                         (b)  The Company may become and remain liable with 
respect to Indebtedness evidenced by the Senior Secured Notes; and any 
Majority-Owned Subsidiary may become and remain liable with respect to 
Indebtedness evidenced by a guaranty thereof (each, a "Guaranty");

                         (c)  The Company or any Majority-Owned Subsidiary, 
as appropriate, may remain liable with respect to any Indebtedness in 
existence on the Seventh Amendment Effective Date;

                         (d)  Subject to the limitations on incurrence of 
Capital Expenditures set forth in Section 8.11 hereof, the Company or any 
Majority-Owned Subsidiary may become and remain liable with respect to 
Indebtedness incurred to acquire equipment (including CT Scanners and MRI 
Units and related additions, parts and improvements);

                         (e)  Any Majority-Owned Subsidiary may become and 
remain liable with respect for Debt for Money Borrowed of such Majority-Owned 
Subsidiary owing to the Company or to a Majority-Owned Subsidiary consisting 
of (i) Indebtedness arising out of an Investment by the Company or such 
Majority-Owned Subsidiary as permitted by Section 8.10(a) through (c) or (ii) 
intercompany operating advances incurred in the ordinary course of business;

                         (f)  In addition to (a) through (e) above, the 
Company or any Majority-Owned Subsidiary may incur and remain liable with 
respect to other Indebtedness not to exceed an aggregate amount of $5,000,000 
at any time outstanding; and

                         (g)  Indebtedness which is a renewal, extension or 
replacement of existing Indebtedness permitted under this Section 8.9; 
provided that the principal amount of the Indebtedness is less than or equal 
to the principal amount outstanding immediately prior to such renewal, 
extension or replacement and that the periodic debt payment with respect 
thereto is less than or equal to the periodic debt payment currently payable 
with respect to such Indebtedness.

                    8.10 INVESTMENTS.   The Company covenants and agrees that 
so long as, and at any time that, (i) any shares of Preferred Stock are held 
by the Investor or any Eligible Holder, and (ii) the IRR Trigger Date has not 
occurred, the Company will not, and will not permit any of its Majority-Owned 
Subsidiaries to, make any Investments other than the following: (a) capital 
contributions and funded loans to any Majority-Owned Subsidiary, and any 
partnership or other joint venture (including a corporate joint venture); 
PROVIDED that the aggregate outstanding amount of all Investments made 
pursuant to this clause (a) does not exceed $5,000,000 at any time; (b) loans 
and advances to employees in the ordinary course of business for a proper 
corporate purpose not to exceed $250,000 in the aggregate at any time 
outstanding

                                                                        Page 50


(excluding notes received from option holders in payment of the exercise 
price of stock options issued pursuant to a stock option plan of the Company 
approved by the Company's Board of Directors); (c) Investments with respect 
to hedging the Company's exposure to foreign currency fluctuations to the 
extent that the Company has sales denominated in such foreign currency; (d) 
Investments in Interest Rate Protection Agreements; (e) short-term operating 
advances described in Section 8.9(f)(ii), to the extent such advances 
constitute Investments; and (f) Investments where the consideration paid by 
the Company consists of equity securities of the Company, to the extent that 
consideration was or is paid in that form.  For purposes of computing the 
amount subject to the $5,000,000 limitation in clause (a) above, (I) there 
shall be excluded Investments where the consideration paid by the Company 
consists of equity securities of the Company, to the extent that 
consideration was or is paid in that form, and (II) there shall be included 
Investments made only from and after the Effective Date of the Tenth Amendment
to the Note Purchase Agreement, and not Investments made prior thereto.

                    8.11 CAPITAL EXPENDITURES.  The Company covenants and 
agrees that so long as, and at any time that, (i) any shares of Preferred 
Stock are held by the Investor or any Eligible Holder, and (ii) the IRR 
Trigger Date has not occurred, the Company will not, and will not permit any 
of its Majority-Owned Subsidiaries to, make Capital Expenditures, unless, 
after including such Capital Expenditures in the aggregate amount of Capital 
Expenditures incurred by the Company and its Majority-Owned Subsidiaries 
during the current Fiscal Year, the aggregate Capital Expenditures for such 
Fiscal Year do not exceed an amount equal to $30,000,000 plus the Capital 
Expenditure Adjustment Amount; PROVIDED, HOWEVER, that the Company or any of 
its Majority-Owned Subsidiaries may dispose of equipment and within 180 days 
purchase replacement equipment with only the net incremental amount being 
deemed to be a Capital Expenditure; PROVIDED, FURTHER, that to the extent the 
Company receives credit against the purchase price of newly-acquired 
equipment as a result of a trade-in of currently-owned equipment, the amount 
of such credit shall not be included in determining the amount of Capital 
Expenditures permitted to be incurred hereunder; and PROVIDED, FURTHER, that 
if the amount of permitted Capital Expenditures for any Fiscal Year is not 
fully utilized, then the unutilized portion (up to 50% of the permitted 
amount for such Fiscal Year) may be carried forward and made in the following 
Fiscal Year, in addition to the amount otherwise permitted for such following 
Fiscal Year.

                         For purposes of this Section 8.11 the incurrence of 
a Capital Expenditure shall be deemed to have occurred when the Company (or 
any of its Majority-Owned Subsidiaries) enters into a binding commitment to 
purchase the applicable equipment as evidenced by a written agreement or 
accepted purchase order between the Company and the manufacturer or seller of 
such equipment. 

                    8.12 TRANSACTIONS WITH AFFILIATES.  The Company covenants 
and agrees that so long as, and at any time that, any shares of Preferred 
Stock are held by the Investor or any Eligible Holder, the Company will not, 
and will not permit any of its Majority-Owned Subsidiaries to, directly or 
indirectly, engage in any transaction with any Affiliate of the Company, 
including, without limitation, the purchase, sale or exchange of 

<PAGE>
                                                                        Page 51


assets or the rendering of any service, except in the ordinary course of 
business and pursuant to the reasonable requirements of the Company's or such 
Majority-Owned Subsidiary's business and upon fair and reasonable terms that 
are no less favorable to the company or such Majority-Owned Subsidiary, as 
the case may be, than those which might be obtained in an arm's-length 
transaction at the time from Persons which are not such an Affiliate.  

                    8.13 LIMITATION ON DISPOSITION OF ASSETS.  The Company 
covenants and agrees that so long as, and at any time that, (i) any shares of 
Preferred Stock are held by the Investor or any Eligible Holder, and (ii) the 
IRR Trigger Date has not occurred, other than as permitted and subject to the 
limitations set forth in Section 8.7 through 8.10 hereof, the Company will 
not, and will not permit any of its Majority-Owned Subsidiaries to, directly 
or indirectly, sell, lease, transfer or otherwise dispose of (other than in 
the ordinary course of business) any of its properties unless (i) after 
giving effect to any such sale, lease, transfer or other disposition by the 
Company or any Majority-Owned Subsidiary, the aggregate net book value of the 
properties involved in such dispositions during any Fiscal Year of the 
Company does not exceed $2,000,000 and in the aggregate at any time after the 
Effective Date of the Tenth Amendment does not exceed $4,000,000 and (ii) 
prior to and after giving effect to any such sale, lease, transfer or other 
disposition by the Company or any Majority-Owned Subsidiary, no Default or 
Event of Default has occurred or is continuing; PROVIDED that the foregoing 
restrictions do not apply to a transfer of properties by a Majority-Owned 
Subsidiary to the Company.

               Notwithstanding the foregoing, the Company or a Majority-Owned 
Subsidiary may make any such disposition and the properties involved in any 
such disposition shall be excluded from the foregoing computation set forth 
in (i) above if within one hundred eighty (180) days after such disposition 
the Company or a Majority-Owned Subsidiary reinvests the proceeds in assets 
substantially similar to those which are disposed of, or applies the net 
proceeds (after deducting direct costs and expenses incurred as a result of 
such disposition and discharging any underlying debt which is secured by such 
property) to the prepayment or redemption of the Secured Obligations or the 
Senior Secured Notes or other Indebtedness of the Company, or retains the 
proceeds in cash or cash-equivalent investments; PROVIDED, FURTHER, that the 
aggregate net book value of properties disposed of under this Section 8.13 
the net proceeds of which are so applied shall not exceed the greater of 
$10,000,000 or fifteen percent (15%) of the net book value of the then 
existing MRI Units.

                    8.14 LIMITATION RELATING TO SUBSIDIARIES.  The Company 
covenants and agrees that so long as, and at any time that, any shares of 
Preferred Stock are held by the Investor or any Eligible Holder, the Company 
will not and will not permit any Majority-Owned Subsidiary to:

                         (a)  transfer any stock of any Majority-Owned 
Subsidiary, or permit any Majority-Owned Subsidiary to issue or transfer its 
stock or transfer the stock of any other Subsidiary, if as a result thereof, 
the Company would own, directly or 

<PAGE>
                                                                        Page 52


indirectly, less than 95% of the Capital Stock or Voting Stock of any 
Majority-Owned Subsidiary, provided that no transfer of any such stock shall 
be permitted unless such transfer is made for fair value, as determined in 
good faith by the Board of Directors of the Company; or

                         (b)  permit any Majority-Owned Subsidiary to enter 
into an agreement restricting it from paying dividends to the Company.

               Notwithstanding the provisions of clause (a) above, all of the 
shares of Capital Stock of all classes of any Majority-Owned Subsidiary owned 
by the Company and/or its Majority-Owned Subsidiaries may be sold for fair 
market value as an entirety if the following conditions are met:

                 (i)    the Majority-Owned Subsidiary whose stock is so sold  
               does not own any shares of capital stock of any other 
               Majority-Owned Subsidiary not being simultaneously sold;
               
                 (ii)   after giving effect to the sale, any Indebtedness of
               the Company or any remaining Majority-Owned Subsidiary owing to
               the Majority-Owned Subsidiary whose stock is so sold could then
               be incurred by the Company or such remaining Majority-Owned
               Subsidiary, as the case may be, under the terms and conditions of
               this Agreement;
               
               (iii)    such sale would be permissible under Section 8.13
               hereunder; and
               
               (iv)     prior to and immediately after giving effect to such
               sale, no Default or Event of Default shall have occurred and be
               continuing under this Agreement or the Senior Secured Notes.
               
                    8.15.LIMITATIONS ON LEASES.  Except as set forth in the 
next sentence, the Company covenants and agrees that so long as, and at any 
time that, (i) any shares of Preferred Stock are held by the Investor or any 
Eligible Holder and (ii) the IRR Trigger Date has not occurred, the Company 
will not, and will not permit any Majority-Owned Subsidiary to, enter into 
any Long-Term Lease, unless, after including in Consolidated Rental 
Obligations the amount of all minimum or guaranteed net rentals the Company 
or such Majority-Owned Subsidiary is directly or indirectly liable for (as 
lessee or as a guarantor or other surety) under such Long-Term Lease which 
will accrue during the 12-month period following the date upon which the 
Company or its Subsidiary enters into such Long-Term Lease, the Consolidated 
Rental Obligations for such 12-month period will not exceed the applicable 
amount set forth below based upon the Fiscal Year in which such Long-Term 
Lease is proposed to be entered into:

               1996                $2,700,000
               1997                $2,500,000
               1998                $2,200,000
               1999                $1,750,000


<PAGE>
                                                                        Page 53


               2000                $1,500,000

                    Notwithstanding the foregoing, there shall be 
excluded from the calculation of Consolidated Rental Obligations pursuant to 
the preceding sentence any and all variable lease payments (i.e., payments 
made pursuant to a Long-Term Lease or otherwise that are based solely upon 
usage or other operating criteria rather than being fixed in amount and as to 
which there are no minimum and no guaranteed periodic payment obligations).  
Notwithstanding the foregoing, for the purposes of this Section 8.15, there 
shall be excluded from the coverage of "Long-Term Leases" and "Consolidated 
Rental Obligations" any lease or other contract or commitment, and payments 
required thereunder, with respect to MRI, CT or other medical equipment and 
related trailers or buildings and related improvements.

                    8.16.BOARD OBSERVATION RIGHTS.   The Company covenants 
and agrees that so long as, and at any time that, any shares of Preferred 
Stock are held by the Investor, the Investor shall be entitled to appoint one 
observer (who may be, but shall not be required to be, an employee of 
Investor) to attend each meeting of the Board of Directors of the Company, 
and shall be entitled to a copy of all written materials (including Board 
meeting agendas and background materials) distributed to each member of the 
Board of Directors of the Company as and when so distributed, subject in each 
case to reasonable safeguards with respect to (i) the protection of the 
Company's highly confidential information (such safeguards to be deemed 
satisfied by the execution of a confidentiality agreement in form and 
substance reasonably satisfactory to the parties) and (ii) conflict of 
interest situations with respect to the business of the Medical Systems 
Division of the Investor.  

                    8.17.NO FUNDED DEBT DEFAULTS.    The Company shall not 
commit or suffer to exist any Funded Debt Default; provided, however, that 
the Company shall not be deemed to have breached this covenant with respect 
to any particular Funded Debt Default if the Investor shall have exercised 
its right under the Series D Certificate of Designation or the Series E 
Certificate of Designation to decline to accept (or shall have been deemed to 
have declined to accept) the Special Dividend Event Repurchase Offer (as 
defined in the Series D Certificate of Designation or the Series E 
Certificate of Designation, as the case may be) related to such Funded Debt 
Default.

                    8.18.NO CHANGE IN BUSINESS.  The Company shall not 
substantially and materially engage in any business other than the business 
of providing diagnostic and therapeutic medical equipment and related 
services to the healthcare industry.

               9.   INDEMNIFICATION
                         
                    9.1  SURVIVAL OF REPRESENTATIONS, WARRANTIES AND 
COVENANTS.  The warranties, representations and covenants of the Company 
contained in or made pursuant to this Agreement shall forever survive the 
execution and delivery of this Agreement and the Closing and shall in no way 
be affected by any investigation of the subject matter thereof made by or on 
behalf of the Investor or the Company; provided, however, that the warranties 
and representations contained in Sections 4.8, 4.9, 4.10, 

<PAGE>
                                                                        Page 54


4.11, 4.12, 4.13, 4.15, 4.16, 4.17, 4.18, 4.19, 4.20, 4.21 and 4.22 shall 
survive for a period of two (2) years after the Closing Date.  As of the 
Closing Date, upon consummation of the transactions contemplated by this 
Agreement, the representations, warranties and covenants contained in the 
Bridge Loan Agreement shall be deemed to be superseded by the provisions of 
this Agreement and shall be of no further force and effect.

                    9.2  INDEMNIFICATION.
                              
                         (a)  The Company shall indemnify and hold harmless 
the Investor and its Affiliates, partners, directors, officers, employees, 
agents and attorneys, in respect of any losses, expenses or Liabilities 
(including any legal and other out-of-pocket expenses for investigating, 
settling or defending any actions or threatened actions) (collectively, 
"Damages") incurred, directly or indirectly, by any of the foregoing in 
connection with any misrepresentation, breach or alleged breach of any 
representation, warranty, covenant or agreement made by the Company in this 
Agreement, the other agreements referred to in this Agreement (except the 
Bridge Loan Agreement), or in any certificate, instrument, schedule or 
document given by the Company to the Investor in connection herewith or 
therewith.

                         (b)  Whenever a representation or warranty contained 
herein is qualified as to materiality, the Company shall have the burden to 
prove by a preponderance of the evidence that the effect of any occurrence, 
event, condition or other factor that makes any representation or warranty 
untrue is not material or was not expected to be material at the time the 
representation or warranty is made.

                         (c)  No Person shall be entitled to indemnification 
pursuant to this Section 9 for any Damages incurred unless the aggregate 
amount for which indemnification is sought is in excess of $50,000, based on 
all Damages from the first dollar and without regard to any materiality 
qualifier (the "Threshold"), whether represented by one or more claims.  If 
the amount of claims for Damages exceeds the Threshold, then the Person 
entitled to indemnification pursuant to this Section 9 shall be entitled to 
indemnification for all Damages, including without limitation the first 
$50,000 of such Damages incurred.

                    9.3  CLAIMS FOR INDEMNIFICATION.  Whenever any claim 
shall arise for indemnification, the indemnified party shall notify the 
Company of the claim in writing and, when known, the facts constituting the 
basis for such claim and the amount or an estimate of the amount of the 
Liability arising from such claim.  The indemnified party shall not settle or 
compromise any claim by a third party that is entitled to indemnification 
hereunder without the prior written consent of the Company unless (i) suit 
shall have been instituted against the indemnified party and (ii) the Company 
shall not have taken control of such suit within fifteen (15) Business Days 
after notification thereof as provided in Section 9.4.

                    9.4  DEFENSE BY THE COMPANY.  In connection with any 
claim giving rise to indemnity hereunder resulting from or arising out of any 
claim or legal 


<PAGE>
                                                                        Page 55


proceeding by a Person other than the Investor, the Company or their 
respective Affiliates, partners, directors, officers, employees, agents or 
attorneys, the Company at its sole cost and expense, may, upon written notice 
to the Investor, assume the defense of any such claim or legal proceeding 
without prejudice to the right of the Company thereafter to contest its 
obligation to indemnify such Person in respect of the claims asserted 
therein.  If the Company assumes the defense of any such claim or legal 
proceeding, the Company shall select counsel to conduct the defense of such 
claims or legal proceedings at its sole cost and expense and shall take all 
steps necessary in the defense or settlement thereof. The Company shall not 
consent to a settlement of, or the entry of any judgment arising from, any 
such claims or legal proceeding, without the prior written consent of the 
indemnified party, unless the Company admits in writing its Liability to hold 
the indemnified party harmless from and against any loss, damages, expenses 
and Liabilities arising out of such settlement and concurrently with such 
settlement the Company pays into court the full amount of all losses, 
damages, expenses and Liabilities to be paid by the Company in connection 
with such settlement.  The indemnified party shall be entitled to participate 
in (but not control) the defense of any such action, with its own counsel and 
at its own expense.  If the Company does not assume the defense of any such 
claim or litigation resulting therefrom in accordance with the terms hereof, 
the indemnified party may defend against such claim or litigation in such 
manner as it may deem appropriate, including settling such claim or 
litigation, after giving notice of the same to the Company, on such terms as 
the indemnified party may deem appropriate.  The Company shall be entitled to 
participate in the defense of any action by the indemnified party, which 
participation shall be limited to contributing information to the defense and 
being advised of its status.  In any action by the indemnified party seeking 
indemnification from the Company in accordance with the provisions of this 
paragraph, the Company shall not be entitled to question the manner in which 
the indemnified party defended such claim or litigation or the amount of or 
nature of any such settlement, except to the extent that the indemnified 
party has breached the provisions of this Section 9.

                    9.5  MATERIALITY.  The parties agree that for all 
purposes of this Agreement, unless specifically stated to the contrary, the 
dollar amounts set forth in various provisions hereof, other than the

                    WITH SECURITIES ACT; REGISTRATION RIGHTS.
                         
                    10.1 RESTRICTIONS ON TRANSFERABILITY.  The Securities 
shall not be sold, assigned, transferred or pledged except upon satisfaction 
of the conditions specified in this Section 10, which conditions are intended 
to ensure compliance with the provisions of the Securities Act.  The Investor 
will cause any proposed purchaser, assignee, transferee, or pledgee of the

                    10.2 RESTRICTIVE LEGEND.  Each certificate representing

following form (in addition to any legend required under applicable state 
securities laws):

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED.  SUCH SHARES MAY NOT BE
          SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN
          EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT
          OR AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH
          REGISTRATION IS NOT REQUIRED.  COPIES OF THE AGREEMENT COVERING THE
          PURCHASE OF THESE SHARES AND RESTRICTING THEIR TRANSFER MAY BE
          OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF
          THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION AT THE PRINCIPAL
          EXECUTIVE OFFICES OF THE CORPORATION.
          
                    10.3 REQUESTED REGISTRATION.
                              
                         (a)  REQUEST FOR REGISTRATION.  In case the Company 
shall receive from the Investor a written request that the Company effect a 
registration under the Securities Act with respect to not less than 3,000,000 
shares of Registrable Securities, the Company will, as soon as practicable, 
use its best efforts to effect such registration (including, without 
limitation, appropriate qualification under applicable blue sky or other 
state securities laws and appropriate compliance with applicable regulations 
issued under the Securities Act and any other governmental requirements or 
regulations) as may be so requested and as would permit or facilitate the 
sale and distribution of all or such portion of such Registrable Securities 
as are specified in such request; PROVIDED, HOWEVER, that the Company shall 
not be obligated to take any action to effect any such registration, 
qualification or compliance pursuant to this Section 10.3 in any particular 
jurisdiction in which the Company would be required to execute a general 
consent to service of process or become subject to taxation in effecting such 
registration, qualification or compliance unless the Company is already subject 
to service or taxation in such jurisdiction.  The Company shall be obligated 
to effect only three such registrations pursuant to this Section 10.3.

                         (b)  UNDERWRITING.  In the event that a registration 
pursuant to this Section 10.3 is for a registered public offering involving 
an underwriting, the Investor shall so advise the Company as a part of its 
request made pursuant to Section 10.3(a).  In such event, the right of the 
Investor to registration pursuant to this Section 10.3 shall be conditioned 
upon the Investor's participation in the underwriting arrangements required 
by this Section 10.3(b), and the inclusion of the Investor's Registrable 
Securities in the underwriting to the extent requested shall be limited as 
provided herein. The Company and the Investor shall enter into an 
underwriting agreement in customary form with managing underwriter(s) 
selected for such underwriting by the Investor, but subject to the Company's 
reasonable approval.  Notwithstanding any other provision of this Section 
10.3, if the managing underwriter(s) advise(s) the Company in writing that 
marketing factors require a limitation of the 


<PAGE>
                                                                        Page 57


number of shares to be underwritten, then the Company shall so advise the 
Investor and the number of shares of Registrable Securities that may be 
included in the registration and underwriting shall be so limited.  If the 
Investor disapproves of the terms of the underwriting, the Investor may elect 
to withdraw therefrom by written notice to the Company.

                         (c)  DEFERRAL BY COMPANY.  Notwithstanding the 
foregoing, the Company shall not be obligated to effect a registration 
pursuant to this Section 10.3 if the Company shall furnish to the Investor a 
certificate signed by the President of the Company stating that in the good 
faith judgment of the Board of Directors of the Company it would be seriously 
detrimental to the Company and its shareholders for the Company to comply 
with such request, and it is therefore essential to defer the filing of the 
registration statement relating thereto.  Any such deferral shall be for a 
period of not more than 90 days after receipt of the Investor's request for 
registration pursuant to Section 10.3(a); PROVIDED, HOWEVER, that the Company 
may not exercise this deferral right more than once in any 12-month period; 
PROVIDED, FURTHER, that any requested registration deferred by the Company 
pursuant to the provisions of this Section 10.3(c) shall thereafter not be 
deemed to be a requested registration for purposes of the limitation to three 
requested registrations pursuant to Section 10.3(a), until such deferral 
expires and the Company effects the related registration. 

                    10.4 COMPANY REGISTRATION.
                              
                         (a)  NOTICE OF REGISTRATION.  If at any time or from 
time to time the Company shall determine to register any of its securities, 
whether or not for its own account, the Company will promptly give to the 
Investor written notice thereof, and include in such registration (and any 
related qualification under blue sky laws or other compliance), and in any 
underwriting involved therein, all the Registrable Securities specified in a 
written request or requests, made within 20 days after receipt of such 
written notice from the Company, by the Investor.

                         (b)  UNDERWRITING.  If the registration of which the 
Company gives notice under this Section 10.4 is for a registered public 
offering involving an underwriting, the Company shall so advise the Investor 
as a part of the written notice given pursuant to Section 10.4(a).  In such 
event the right of the Investor to registration pursuant to this Section 10.4 
shall be conditioned upon the Investor's participation in such underwriting 
and the inclusion of the Investor's Registrable Securities in the 
underwriting to the extent provided herein.  The Investor and the Company 
shall enter into an underwriting agreement in customary form with the 
managing underwriter selected for such underwriting by the Company.  
Notwithstanding any other provision of this Section 10.4, if the managing 
underwriter determines that marketing factors require a limitation of the 
number of shares to be underwritten, the managing underwriter may limit the 
Registrable Securities to be included in such registration, and the Company 
shall include in such registration: (i) first, 100% of the securities the 
Company proposes to sell for its own account, and (ii) second, such number of 
Registrable Securities which the Investor has requested to be included in 
such registration and such number of securities which other holders have 
requested to be included in such registration which, 


<PAGE>
                                                                        Page 58


in the opinion of such managing underwriter, can be sold without having an 
adverse effect on the marketing of the securities referred to above, such 
number of Registrable Securities and securities of other holders described in 
this clause (ii) to be included on a pro rata basis among the Investor and 
all other holders.  To facilitate the allocation of shares in accordance with 
the above provisions, the Company may round the number of shares allocated to 
the Investor or other holders to the nearest 100 shares.  If the Investor 
disapproves of the terms of any such underwriting, he may elect to withdraw 
therefrom by written notice to the Company and the managing underwriter.  

                         (c)  RIGHT TO TERMINATE REGISTRATION.  The Company 
shall have the right to terminate or withdraw any registration initiated by 
it under this Section 10.4 prior to the effectiveness of such registration 
whether or not the Investor has elected to include securities in such 
registration.

                    10.5 REGISTRATION ON FORM S-3.  If the Investor requests 
that the Company file a registration statement on Form S-3 (or any successor 
form to Form S-3) for a non-underwritten public offering of the Registrable 
Securities, the reasonably anticipated aggregate price to the public of 
which, net of discounts and commissions, would exceed $12,000,000 and the 
Company is then entitled to use Form S-3 under applicable SEC rules to 
register the Registrable Securities for such an offering, the Company shall 
use its best efforts to cause such Registrable Securities to be registered 
for the offering on such form and to cause such Registrable Securities to be 
qualified in such jurisdictions as the Investor may reasonably request; 
provided, however, that the Company shall not be required to effect more than 
one registration pursuant to this Section 10.5 in any twelve (12) month 
period or in excess of three (3) registrations under this Section 10.5; 
PROVIDED, HOWEVER, that the Company shall not be obligated to take any action 
to effect any such registration, qualification or compliance pursuant to this 
Section 10.5 in any particular jurisdiction in which the Company would be 
required to execute a general consent to service of process or become subject 
to taxation in effecting such registration, qualification or compliance 
unless the Company is already subject to service or taxation in such 
jurisdiction.  The substantive provisions of Section 10.3(b) shall be 
applicable to each registration initiated under this Section 10.5.

                    10.6 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS.  From 
and after the Closing Date, the Company shall not enter into any agreement 
granting any holder or prospective holder of any securities of the Company 
registration rights with respect to such securities unless (i) such new 
registration rights are on a pari passu basis with those rights of the 
Investor hereunder, or (ii) such new registration rights are subordinate to 
the registration rights granted to the Investor hereunder.  

                    10.7 EXPENSES OF REGISTRATION.  All expenses (other than 
underwriting discounts and commissions relating to Registrable Securities and 
fees and disbursements of counsel for the Investor), including without 
limitation all registration, filing, and qualification fees, printing and 
accounting fees and legal fees and expenses of counsel to the Company 
incurred in connection with any registration pursuant to Section 10.3, 10.4 
or 10.5 shall be borne by the Company.

                    10.8 SECURITIES INDEMNIFICATION.  The Company will 
indemnify the Investor, each of its officers, directors and partners, and 
each Person controlling such Investor within the meaning of Section 15 of the 
Securities Act, with respect to which registration, qualification or 
compliance has been effected pursuant to this Section 10, and each 
underwriter, if any, and each Person who controls any underwriter within the 
meaning of Section 15 of the Securities Act, against all expenses, claims, 
losses, damages or liabilities (or actions in respect thereof), including any 
of the foregoing incurred in settlement of any litigation, commenced or 
threatened, arising out of or based on any untrue statement (or alleged 
untrue statement) of a material fact contained in any registration statement, 
prospectus, offering circular or other document, or any amendment or 
supplement thereto, incident to any such registration, qualification or 
compliance, or based on any omission (or alleged omission) to state therein a 
material fact required to be stated therein or necessary to make the 
statements therein, in light of the circumstances in which they were made, 
not misleading, or any violation by the Company of the Securities Act or any 
rule or regulation promulgated under the Securities Act applicable to the 
Company in connection with any such registration, qualification or 
compliance, and the Company will reimburse the Investor, each of its officers 
and directors, and each Person controlling the Investor, each such 
underwriter and each Person who controls any such underwriter, for any legal 
and any other expenses reasonably incurred in connection with investigating, 
preparing or defending any such claim, loss, damage, liability or action, 
provided that the Company will not be liable in any such case to the extent 
that any such claim, loss, damage, liability or expense arises out of or is 
based on any untrue statement or omission or alleged untrue statement or 
omission, made in reliance upon and in conformity with written information 
furnished to the Company by an instrument duly executed by the Investor, 
controlling Person or underwriter and stated to be specifically for use 
therein. The procedures governing the securities indemnification obligations 
of the Company under this Section 10.8 shall be as set forth in Section 9.  
The indemnification obligations of the Company under this Section 10.8 shall 
be in addition to the indemnification obligations of the Company under 
Section 9.

                    10.9 TRANSFER OF REGISTRATION RIGHTS.  The rights to 
cause the Company to register securities granted to Investor under Sections 
10.3, 10.4, and 10.5 may be assigned to a transferee or assignee reasonably 
acceptable to the Company in connection with any transfer or assignment of 
Registrable Securities by the Investor provided that such transfer may 
otherwise be effected in accordance with applicable securities laws.  

               11.  MISCELLANEOUS.
                         
                    11.1 EXPENSES.  At Closing, the Company shall promptly pay 
the Investor all of the Investor's reasonable out-of-pocket expenses incurred in
connection with this transaction, including legal fees and expenses, accounting

maximum responsibility therefor shall be Ninety Thousand Dollars ($90,000).
