BASIS OF PREPARATION

     The accompanying unaudited condensed consolidated financial statements 
have been prepared by Alliance Imaging, Inc. (the Company) in accordance with 
generally accepted accounting principles for interim financial information and 
with the instructions to Form 10-Q and Article 10 of Regulation S-X of the 
Securities and Exchange Commission.  Accordingly, they do not include all of 
the information and footnotes required by generally accepted accounting 
principles for complete financial statements.  In the opinion of the Company, 
all adjustments (consisting of normal recurring accruals) considered necessary 
for a fair presentation have been included.  Operating results for the three 
month period ended March 31, 1996, are not necessarily indicative of the 
results that may be expected for the year ending December 31, 1996.  For 
further information, refer to the consolidated financial statements and 
footnotes thereto included in the Company's annual report on Form 10-K for the 
year ended December 31, 1995.

     The earnings per common share for the three month period ended March 31, 
1996 calculation is based upon average common and common equivalent shares 
outstanding during the period, and reflects preferred dividend requirements 
totaling $233,000.  Common equivalent shares include vested stock options with 
an exercise price lower than current market value.

     The provision for income taxes for the three months ended March 31, 1996 
is less than the statutory federal rate due to utilization of certain net 
operating loss carryforwards during the period.

                    Management's Discussion and Analysis of
                 Financial Condition and Results of Operations


GENERAL

     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 increasing cost 
containment pressures which management believes have resulted in decreasing 
revenues per scan.  The Company expects pricing levels to continue to decline 
moderately in the immediate future.  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 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.

     In response to these operating challenges, the Company has implemented 
numerous cost containment and efficiency measures to reduce operating, payroll 
and selling, general and administrative costs.  It has also refocused and 
expanded its sales and marketing efforts and embarked on a major MRI fleet 
upgrade program.  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 fleet to remain competitive in the 
marketplace.

     Beginning in late 1993, the Company commenced a continuing review of the 
carrying value of certain older equipment and other assets, as well as its 
capital structure, in view of then current operating conditions.  As a result, 
the Company recorded non-cash asset impairment


                                      7

<PAGE>

charges in 1993 and 1994, and began an ongoing equipment trade-in and upgrade 
program to improve the marketability and productivity of the Company's MRI and 
CT systems.  In addition, the Company completed a comprehensive financial 
restructuring with the holders of its senior notes and senior subordinated 
debentures effective December 31, 1994.  For further details concerning these 
matters, please refer to the Company's 1995 Annual Report to Stockholders.

RESULTS OF OPERATIONS - COMPARISON OF QUARTER ENDED MARCH 31, 1996 TO QUARTER 
ENDED MARCH 31, 1995

     Revenues for the first three months of 1996 were $14,685,000, an increase 
of $204,000, or 1.4%, over 1995.  Excluding the revenues of $760,000 from 
operations which were sold in the second half of 1995, the increase in 
revenues was $964,000, or 7.0%.  This increase reflects a scan-based MRI 
revenue increase of $510,000, or 4.1%, resulting from a 7.6% increase in scan 
volume partially offset by a 3.3% decrease in the average revenue realized per 
MRI scan. Management attributes the volume increase to the Company's 
continuing fleet upgrade program, which has enabled the Company to obtain new 
long-term contracts from both existing and new customers.  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.  Revenue under fixed fee 
contracts increased $258,000, or 76.6%, resulting from an increased number of 
MRI systems under interim rental contracts. Other revenue increased $196,000, 
primarily as a result of the third quarter 1995 acquisition of a mobile CT 
business.

     The Company's fleet included 81 MRI systems at March 31, 1996 compared to 
72 MRI systems at March 31, 1995.  The average number of MRI systems operated 
by the Company was 80.5 during the first quarter of 1996, compared to 69 
during the first quarter of 1995.

     Operating expenses, excluding depreciation, totaled $7,181,000 in the 
first three months of 1996, an increase of $12,000, or 0.2%, from first 
quarter 1995.  Excluding expenses of $326,000 related to operations which were 
sold in the second half of 1995, the increase in operating expenses was 
$338,000, or 4.9%.  Payroll and related employee expenses increased $180,000, 
or 6.5%.  Maintenance and cryogen contract and repairs expense increased 
$160,000, or 6.4%.  These increases resulted from a higher number of MRI 
systems in operation in the 1996 first quarter.

     Depreciation expense during the first three months of 1996 decreased 
$126,000, or 4.2%, from the 1995 level due to a lower amount of depreciable 
assets, primarily resulting from asset sales in late 1995 partially offset by 
equipment additions in the first quarter of 1996. Amortization expense in the 
1996 first quarter increased $13,000, or 3.9%, over the 1995 period as a 
result of two acquisitions, one in the third quarter of 1995 and the other in 
the first quarter of 1996.

     Selling, general and administrative expenses totaled $1,507,000 in the 
first quarter of 1996, a decrease of $35,000, or 2.3%, from the first quarter 
of 1995.  Bad debt expense decreased


                                      8

<PAGE>

$34,000, or 45.3%, in the first three months of 1996 as a result of revised 
billing practices and continuing intensive collection efforts, primarily with 
respect to the Company's retail accounts receivable.  Other expense categories 
were essentially unchanged from the prior period.

     Interest expense of $1,185,000 in the first three months of 1996 was 
$69,000, or 5.5%, lower than the same period in 1995 primarily as a result of 
lower average outstanding debt balances during the first quarter of 1996 as 
compared to the first quarter of 1995.

     An income tax provision of $239,000 was recorded in the first quarter of 
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 the first quarter of 1995, an income tax provision of 
$172,000 was recorded, also related to certain federal alternative minimum 
taxes and state tax liabilities.  The Company's effective tax rate was 
approximately constant at 15% of pre-tax income.

     The Company's net income was $1,363,000 in the first quarter of 1996 
compared to net income of $1,021,000 in  the first quarter of 1995, an 
increase of $342,000, or 33.5%, primarily attributable to increased revenues 
and lower selling, general and administrative and depreciation and interest 
expense.  Earnings per common share totaled $.10 in the first quarter of 1996, 
compared to earnings per common share of $.07 for the same period in 1995, an 
increase of 42.9%.  The earnings per common share calculations reflect 
preferred dividend requirements of $233,000 in the first quarter of 1995 and 
1996.

LIQUIDITY AND CAPITAL RESOURCES

     At March 31, 1996, cash and short-term investments were $11,920,000 
compared to $11,128,000 at December 31, 1995, and the aggregate of the 
Company's long-term debt and senior subordinated debentures was $67,047,000 
compared to $65,932,000 at December 31, 1995.  The Company obtained a 
$3,000,000 revolving line of credit secured by accounts receivable in December 
1995.  This line, which has not been utilized, is intended to act as a 
temporary supplement to fund working capital needs. 

     The Company generated $4,619,000 in net cash from operating activities 
during the first three months of 1996, compared to $2,682,000 during 1995's 
first three months.  This cash flow was sufficient to meet the Company's debt 
service obligations and capital expenditures not financed.  During the first 
quarter of 1996, the Company financed $4.3 million of capital expenditures and 
repaid $2.5 million of long-term debt.  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.

     Debt service requirements on the Company's restructured senior notes, 
with a balance of $26,600,000 at March 31, 1996 require quarterly payments of 
interest at 7.5%, plus aggregate principal payments of $400,000 in 1996 
(gradually increasing to $7,200,000 in 2003).  The Company made an additional 
$1,000,000 principal payment in April 1996 in connection with the lender's 
agreement to increase capital expenditure limitations (see below).  The senior


                                      9

<PAGE>

subordinated debentures with a balance of $16,445,000 at March 31, 1996, 
require quarterly payments of $187,500 through 2003 (increasing to 
approximately $1,900,000 in 2004 and 2005) which, for financial statement 
purposes, are recorded as principal reductions; no interest expense will be 
recorded during the contractual term of the debentures, in accordance with 
generally accepted accounting principles.

     The Company's Series A preferred stock, with a balance of $16,663,000 
(including accumulated dividends of $1,163,000) at March 31, 1996, bears a 
dividend at 6% of its original liquidation value ($15,500,000) annually.  
However, dividends may be paid in cash only if certain defined operating cash 
flow levels are achieved or to the extent of proceeds from the sale of new 
common equity.  The Company's 1995 cash flow substantially exceeded the level 
required to pay the 1995 Series A preferred stock dividend in cash and such 
dividend was paid in April 1996 in the amount of $930,000.  Although the 
Company expects to be able to pay the Series A preferred stock dividends 
attributable to 1996 and subsequent years in cash, there can be no assurance 
that future cash flow levels will be sufficient to permit the payment of such 
future dividends in cash.  If annual cash dividends are not or cannot be paid, 
dividends will be payable in Series B preferred stock, which has no dividend 
requirement and is convertible into common stock at specified prices.  
Consequently, substantial amounts of common stock equivalents may be issued to 
the holders of the Series A preferred stock in the future, which would cause 
significant dilution to present common stockholders.  Both series of preferred 
stock have mandatory redemption requirements (in the case of Series B, if not 
previously converted to common stock) applicable after the senior notes and 
senior subordinated debentures are fully repaid.

     The senior notes, senior subordinated debentures and certain other credit 
agreements contain various covenants related to financial ratios and other 
matters.  The Company was in compliance with these covenants at March 31, 1996.

CAPITAL EXPENDITURES

     The Company purchased two new high-field MRI systems and upgraded five 
MRI systems at a total approximate cost of $6,200,000 during the first quarter 
of 1996.  The Company currently plans to purchase seven additional high-field 
MRI systems in 1996 and plans to upgrade several existing systems.  The 
Company's senior secured and subordinated lenders have recently agreed to 
increase the Company's allowable capital expenditures to a total of $34 
million in 1996 and 1997, an increase of $14 million from previous levels.  
Consequently, the Company may purchase or upgrade several more systems in 1996 
as opportunities to place new equipment into service arise as future contracts 
are signed and existing contracts are renewed.

     In addition, the Company expects to dispose of substantially all of its 
remaining less technologically advanced systems in 1996 in exchange for new or 
used MRI systems.  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.


                                      10

<PAGE>

     In February 1996, the Company acquired four MRI systems and associated 
MRI contracts from Mobile M.R. Venture, Ltd.  In April 1996, the Company 
acquired Royal Medical Health Services, Inc., including six MRI systems.  
These transactions were primarily funded from existing cash reserves.  
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 
and long-term secured or unsecured financing, if available.

     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.

criteria rather than being fixed in amount and as to which there are no minimum

     NOW, THEREFORE, in consideration of the premises and the agreements,

         the "Supplemental Mandatory Principal Prepayments"):

         (i)  The amount of each Excess Cash Cap Ex Payment (as 
         defined in Section 10.08).  Each prepayment pursuant to this 
         Section 6.02(i) shall be made in four equal quarterly

         prepayment pursuant to this Section 6.02(iii) shall be made 
         simultaneously with the closing of such acquisition.

         The payment of Supplemental Mandatory Principal Prepayments 
         shall be applied first against the last remaining unpaid 
         mandatory prepayment described in the first sentence of this 
         Section 6.02, then to the second to last remaining unpaid 
         mandatory prepayment, and so on (i.e., such payments will be 
         applied in reverse order of maturity)."

              and thereafter


 .3  REFINANCINGS.

     Section 10.03(h) of the Purchase Agreement is amended and restated to 
read in full as follows:  "Indebtedness which is a renewal, extension or 
replacement of existing Indebtedness permitted under this Section 10.03; 
provided that (A) in the case of such Indebtedness which is a renewal, 
extension or replacement of existing Indebtedness incurred to acquire

is less than or equal to the periodic debt payment currently payable with 
respect to the existing Indebtedness being renewed, extended or replaced,

payment currently payable with respect to such Indebtedness."

     .4  RESTRICTED PAYMENTS.

     Clause (a) of Section 10.05 of the Purchase Agreement, beginning with 
the first word of that clause and ending immediately prior to the first 
instance of "(i)" therein, is amended and restated to read as follows: 
"payments made by the Company to pay cash dividends on Preferred Stock issued 
to the holders of the Subordinated Debentures on the Seventh Amendment 
Effective Date and to pay cash dividends on the Series C 5% Cumulative 
Convertible Redeemable Preferred Stock of the Company (the "Series C 
Preferred Stock"), provided that 

                                     -3-

<PAGE>

in the case of such Series C Preferred Stock the amount of cash dividends 
shall not exceed $20,000 per year, and provided further that any such 
dividend payments shall be made".  Section 10.05(a) is also hereby amended to 
add thereto as two new final sentences the following:  "The Company shall be 
required to make mandatory prepayments on the Notes in connection with the 
making of cash dividends on the Series C Preferred Stock, as indicated in 
Section 6.02 of this Agreement.  In addition to the foregoing exceptions, the 
Company shall be permitted to make cash payments in lieu of issuing 
fractional shares in connection with a recapitalization of its Common Stock 
(including a reverse stock split thereof) or any similar event, provided that 
the aggregate amount expended therefor from and after the date of this Ninth 
Amendment and prior to the repayment in full of the Senior Notes shall not 
exceed the lesser of $25,000 and the actual amount expended to effect the 
first such recapitalization or similar event."

 .5  FIXED PAYMENT AND FIXED CHARGE COVERAGE RATIOS.

     Section 10.07 of the Purchase Agreement is amended by changing the 
figures under the columns "Minimum Fixed Payment Ratio" and "Fixed Charge 
Coverage Ratio" for the indicated years as follows:


                          Minimum Fixed           Fixed Charge 
                          Payment Ratio          Coverage Ratio 
                         ---------------        ----------------

           and thereafter 


In addition, the following new sentence is added at the end of Section 10.07: 
"The amount of Supplemental Mandatory Principal Prepayments (as defined in 
Section 6.02) shall be excluded from the computation of the Minimum Fixed 
Payment Ratio for purposes of this Section 10.07."

     .6  CAPITAL EXPENDITURES.

     The first sentence of Section 10.08 of the Purchase Agreement is amended 
to add the phrase "Except as set forth in the next sentence," to the 
beginning of such sentence.  Two new sentences, placed after the existing 
first sentence, of Section 10.08 are added as follows:  "During the two 
Fiscal Years

                                     -4-

<PAGE>

such excess Capital Expenditures shall not exceed $14,000,000 during the 
Special Cap Ex Period, and provided further that the aggregate amount of such 
excess cash payments made in respect of Capital Expenditures shall not exceed 
$3,500,000 during the Special Cap Ex Period (each cash payment made in 
reliance on this sentence is referred to herein as an "Excess Cash Cap Ex 
Payment").  The Company shall be required to make mandatory prepayments on 
the Notes in connection with each Excess Cash Cap Ex Payment, as indicated in 
Section 6.02 of this Agreement."

     .7  LIMITATION ON LEASES.

     The first sentence of Section 10.14 of the Purchase Agreement is amended 
to add the phrase "Except as set forth in the next sentence," to the 
beginning of such sentence.  The reference to "$1,500,000" at the end of such 
sentence is stricken and in lieu thereof the following text is inserted: 

             "the applicable amount set forth below based upon the 
             Fiscal Year in which such Long-Term Lease is proposed 
             to be entered into:

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)."

     SECTION 2.     CONSIDERATION FOR NINTH AMENDMENT

     In consideration of their agreement to enter into this Ninth Amendment, 
the Company agrees to pay the holders of the Notes an aggregate cash fee of 
$75,000, such amount to be paid to such holders pro rata in accordance with 
the respective remaining unpaid principal amounts of the Notes held by each 
of such holders as of the date of this Ninth Amendment ("Pro Rata").  Such 
payment will be made on the earliest date that all of the parties to this 
Ninth Amendment have executed and delivered it.  In addition, in 
consideration of their agreement to enter into this Ninth Amendment, on the 
same date referred to in the preceding sentence, the Company shall issue to 
the holders of the Notes warrants to purchase an aggregate of 11,200 shares

entitled to receive warrants may elect in lieu thereof (by written notice to 
the Company prior to the execution and delivery of this Ninth Agreement by 
such holder) to receive an additional cash payment calculated at the rate of 
$1.875 for each warrant to purchase one share of Common Stock foregone.

     SECTION 3.  APPROVAL OF ROYAL TRANSACTION

     In consideration of the Company's agreements in this Ninth Amendment,

Holders) by the Company or a Subsidiary thereof of the capital stock of Royal 
Medical Health Services, Inc., a Pennsylvania corporation, and the creation 
of a Subsidiary in order to accomplish such acquisition, for purposes of 
Section 10.17 of the Purchase Agreement.  The Company agrees that, not later 
than the closing of such acquisition, the Subsidiary created or acquired as a 
result of such acquisition or surviving any merger to accomplish such 
acquisition will execute and deliver to each of the holders of Notes a 
Guaranty.  Simultaneously with the execution and delivery of this Ninth 
Amendment by the Company, the Company shall provide or cause to be provided 
to the Holders certified resolutions of the Board of Directors of the entity 
providing such Guaranty approving such acquisition and authorizing the 
execution and delivery of such Guaranty and a legal opinion of Irell & 
Manella LLP as to the enforceability of such Guaranty against such entity in 
form and substance reasonably satisfactory to the Holders.

               OF SERIES C 5% CUMULATIVE CONVERTIBLE REDEEMABLE
                                PREFERRED STOCK

            (Pursuant to Section 151(g) of the General Corporation
                        Law of the State of Delaware.)



     Alliance Imaging, Inc., a corporation organized and existing under the
laws of the State of Delaware (the "COMPANY"), DOES HEREBY CERTIFY THAT,
pursuant to authority conferred upon the Board of Directors of the Company (the
"BOARD") by the Restated Certificate of Incorporation of the Company, as
amended (the "CERTIFICATE OF INCORPORATION"), the Board, pursuant to a
unanimous written consent dated as of April [__], 1996, adopted the following
resolutions authorizing the issuance of Series C 5% Cumulative Convertible
Redeemable Preferred Stock of the Company, which resolutions are still in full
force and effect and are not in conflict with any provisions of the Certificate
of Incorporation or Bylaws of the Company:

     RESOLVED, that pursuant to authority vested in the Board by the
Certificate of Incorporation, the Board does hereby establish a series of
Preferred Stock of the Company from the Company's authorized class of 1,000,000
shares of $0.01 par value preferred shares, such series to consist of 4000
shares, which number may be decreased (but not below the number of shares
thereof then outstanding) from time to time by the Board, and to the extent
that the voting rights, designation, powers, preferences and relative
participating, optional or other special rights and the qualifications,
limitations or restrictions of that series are not stated and expressed in the
Certificate of Incorporation, does hereby fix and state the voting rights,
designation, powers, preferences and relative participating, optional or other
special rights and the qualifications, limitations or restrictions thereof, as
follows:

<PAGE>

     1.  DEFINITIONS.  Unless otherwise specified herein, the following
capitalized terms shall have the meanings ascribed to them below:

         A.  COMMON STOCK.  "COMMON STOCK" shall mean the Company's Common
Stock, $0.01 par value per share.

         B.  DGCL.  "DGCL" shall mean the Delaware General Corporation Law.

         C.  FACE AMOUNT.  The "FACE AMOUNT" of each share of Series C Stock 
(as defined below), regardless of its par value, shall be One Hundred Dollars
($100.00), as the Series C Stock is presently constituted, such amount to be
proportionately adjusted to reflect any combination, consolidation,
reclassification or like adjustment to the Series C Stock.

         D.  MARKET PRICE.  The "MARKET PRICE" of a share of Common Stock on
or with respect to any day shall mean (i) the closing sales price on the
immediately preceding trading day of a share of Common Stock on the principal
national securities exchange or automated quotation system on which the shares
of Common Stock are listed or admitted to trading or, if not listed or admitted
to trading on any national securities exchange or automated quotation system,
the average of the last reported bid and asked prices on such immediately
preceding trading day in the over-the-counter market as furnished by the
National Association of Securities Dealers, Inc., or, if such firm is not then
engaged in the business of reporting such prices, as furnished by any similar
firm then engaged in such business selected in good faith by the Company or, if
there is no such firm, as furnished by any member of the National Association
of Securities Dealers, Inc., selected in good faith by the Company, or (ii) if
the shares of Common Stock are not then traded on any such exchange or system,
the amount determined in good faith by the Board to represent the fair value of
a share of Common Stock, which determination shall be conclusive.

     2.  DESIGNATION OF SERIES; ISSUANCE AND FACE AMOUNT.  This series of
Preferred Stock is designated "Series C 5% Cumulative Convertible Redeemable
Preferred Stock" (the "SERIES C STOCK"), and the number of shares which shall
constitute such series shall be 4000, which number may be 

                                     -2-

<PAGE>

decreased (but not below the number thereof then outstanding) from time to 
time by the Board.  The shares of Series C Stock shall be issued by the 
Company for their Face Amount (as herein defined), in such amounts, at such 
times and to such persons as shall be specified by the Board, from time to 
time.  Fractional shares of Series C Stock may be issued.

     3.  RANK; SENIOR AND JUNIOR SECURITIES.  The Series C Stock shall, with
respect to dividend rights and rights on liquidation, winding up and
dissolution, rank junior to all Senior Securities and senior to all Junior
Securities, all as more fully set forth herein.  For purposes hereof, "SENIOR
SECURITIES" shall mean the Company's Series A 6.0% Cumulative Preferred Stock
("SERIES A STOCK"), the Company's Series B Convertible Preferred Stock ("SERIES
B STOCK"), and all other classes and series of stock of the Company hereafter
authorized, issued or outstanding except for Junior Securities and any classes
or series of stock or other securities of the Company that are designated as
equal in rank to the Series C Stock with respect to dividend rights and rights
on liquidation, winding up and dissolution by (i) the Board pursuant to the
authority granted to it under Article FOUR of the Company's Certificate of
Incorporation or (ii) amendment to the Certificate of Incorporation duly
adopted by the Company and its stockholders as provided pursuant to the DGCL.
For purposes hereof, "JUNIOR SECURITIES" shall mean the Common Stock, any other
class or series of the Company's common equity, and such other classes or
series of stock and other securities of the Company as shall be designated as
junior to the Series C Stock with respect to dividend rights and rights on
liquidation, winding up and dissolution by (i) the Board pursuant to the
authority granted to it under Article FOUR of the Company's Certificate of
Incorporation or (ii) amendment to the Company's Certificate of Incorporation
duly adopted by the Company and its stockholders as provided pursuant to the
DGCL.

     4.  DIVIDENDS.

         A.  AMOUNT.  The holders of shares of the Series C Stock shall be
entitled to receive, when, as and if declared by the Board, out of funds
legally available therefor, cash dividends at the rate of 5% per annum of the
Face Amount per 

                                     -3-

<PAGE>

share, and no more.  Declared dividends shall be paid pro rata to the holders 
entitled thereto.

         B.  CUMULATION AND TIME OF PAYMENT.  The dividends indicated in
paragraph 4.a shall be cumulative and shall accrue from day to day, whether or
not earned or declared, commencing with the date of issue of the particular
shares of Series C Stock or from the most recent preceding Dividend Payment
Date (as defined below) through which all dividends have been paid, whichever
is later.  Dividends with respect to any year, as and if declared by the Board,
shall be payable annually at a date to be designated by the Board which falls
within the last fifteen days (or, if the Board of Directors has not designated
a day, the last day) of April of the succeeding year (each such date being a
"Dividend Payment Date"), the first such Dividend Payment Date being within the
last fifteen days of April 1997.  No undeclared or unpaid dividend shall bear
or accrue interest.

         C.  PAYMENT OF ACCUMULATED DIVIDENDS.  Accumulated dividends not
paid on prior Dividend Payment Dates may be declared by the Board and paid to
the holders of record of outstanding shares of Series C Stock as their names
shall appear on the stock register of the Company on a record date to be
established by the Board, which record date shall be not more than sixty (60)
nor less than thirty (30) days preceding the date of payment, whether or not
such date is a Dividend Payment Date.  Holders of outstanding shares of
Series C Stock shall not be entitled to receive any dividends in excess of the
full cumulative dividends to which such holders are entitled as herein
provided.  Any payment of accumulated dividends pursuant to this provision
shall be applied first to accumulated dividends relating to the earliest
Dividend Payment Date for which dividends were not paid, then to the next such
Dividend Payment Date, and so on, up to and including the most recent Dividend
Payment Date for which dividends were not paid.

         D.  PRIORITY OF CUMULATIVE DIVIDENDS.  In addition to certain other
restrictions contained herein, so long as any shares of Series C Stock are
outstanding, the Company shall not (i) declare, pay or set apart for payment
any dividend on, or make any distribution in respect of, the Junior Securities
or any warrants, rights, calls or options exercisable for or

                                     -4-

<PAGE>

convertible into any of the Junior Securities, either directly or indirectly, 
whether in cash, obligations or shares of the Company or other property 
(other than distributions or dividends of a particular class or series of 
Junior Securities, or warrants, rights or options exercisable for such Junior 
Securities, to holders of such Junior Securities), or (ii) make any payment 
on account of, or set apart for payment money for a sinking or other similar 
fund for, the purchase, redemption, retirement or other acquisition for value 
of any of, or redeem, purchase, retire or otherwise acquire for value any of, 
the Junior Securities (other than as a result of a reclassification of Junior 
Securities into other Junior Securities or the exchange or conversion of one 
class or series of Junior Securities for or into another class or series of 
Junior Securities) or any warrants, rights, calls or options exercisable for 
or convertible into any of the Junior Securities, or (iii) permit any 
corporation or other entity directly or indirectly controlled by the Company 
to purchase, redeem, retire or otherwise acquire for value any of the Junior 
Securities or any warrants, rights, calls or options exercisable for or 
convertible into any of the Junior Securities, unless, and in each such case, 
prior to or concurrently with such declaration, payment, setting apart for 
payment, purchase, redemption, retirement or other acquisition for value or 
distribution in respect of Junior Securities, all accumulated and unpaid 
dividends (including accumulated dividends, if any, not paid by reason of the 
terms and conditions of Section 4.e hereof), if any, on shares of Series C 
Stock shall have been paid through the most recent Dividend Payment Date or, 
if such declaration, payment, setting apart for payment, purchase, 
redemption, retirement, other acquisition for value or distribution occurs on 
a Dividend Payment Date, through such Dividend Payment Date; PROVIDED, 
HOWEVER, that the restrictions provided in this subparagraph d. shall not 
apply to the repurchase of shares of Common Stock held by any employee or 
consultant of the Company or any of its subsidiaries (or their permitted 
transferees) in connection with the termination of such employee's or 
consultant's services to the Company or any of its subsidiaries.

         E.  RESTRICTIONS ON PAYMENT OF DIVIDENDS.  Notwithstanding anything
contained herein to the contrary, no cash dividends on shares of Series C Stock
shall be declared

                                     -5-

<PAGE>

by the Board or paid or set apart for payment by the Company: (i) unless, 
prior to or concurrently with such declaration, payment or setting apart, all 
accrued and unpaid dividends, if any, on shares of Senior Securities shall 
have been paid or declared and set apart for payment through the dividend 
payment period with respect to such Senior Securities which immediately 
precedes or coincides with the date of declaration, payment or setting apart 
for payment by the Company of such cash dividends; or (ii) at such time as 
such declaration, payment or setting apart is prohibited by the DGCL; or 
(iii) at such time as the terms and provisions of any contract or other 
agreement of the Company or any of its subsidiaries entered into or assumed 
providing financing or working capital to the Company or any of its 
subsidiaries (whether entered into prior to, at or after the issuance of the 
Series C Stock), specifically prohibits such declaration, payment or setting 
apart for payment or provides that such declaration, payment or setting apart 
for payment would constitute a breach thereof or a default thereunder.

     5.  LIQUIDATION PREFERENCE.

         A.  GENERAL.  In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Company, the
holders of Series C Stock shall be entitled to receive, prior and in preference
to any distribution of any of the assets or surplus funds of the Company in
respect of any Junior Securities, but after all required distributions of
assets and surplus funds in respect of any Senior Securities, an amount equal
to the Face Amount per share plus accumulated and unpaid dividends to the date
fixed for liquidation, dissolution or winding up.  Upon any liquidation,
dissolution or winding up of the Company, after payment shall have been made in
full on the Series C Stock as provided in the preceding sentence, but not prior
thereto, the holders of Junior Securities shall, subject to the respective
terms and provisions applying thereto, if any, be entitled to receive any and
all assets and surplus funds remaining to be paid or distributed, and the
Series C Stock shall not be entitled to share therein.

         B.  DISTRIBUTIONS PRO RATA.  If upon any liquidation, dissolution or
winding up of the Company the amounts payable on or with respect to the Series
C Stock are 

                                     -6-


<PAGE>

not paid in full, the holders of shares of Series C Stock together
with all classes or series of stock ranking on a parity with the Series C Stock
as to distribution of assets and surplus funds 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 the Series C Stock and any other class or
series of stock that so ranks on a parity with the Series C Stock were paid in
full.

         C.  MERGER OR CONSOLIDATION.  Neither the merger nor consolidation
of the Company with another corporation nor the sale or lease of all or
substantially all of the assets of  the Company shall be deemed to be a
liquidation, dissolution or winding up of the Company.

         D.  NOTICE REQUIRED.  Written notice of any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Company, 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 C
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 C Stock
shall have the right, at his or her option, at any time and from time to time
after issuance of the Series C Stock, to convert, subject to the terms and
provisions of this Section 6, all or any portion of its Series C Stock then
outstanding into fully paid and non-assessable shares of Common Stock at a
conversion rate of twenty (20) shares of Common Stock for each one (1) share of
Series C Stock (the "CONVERSION RATE").  At the time of any such conversion,
any accumulated and unpaid dividends on the Series C Stock to be so converted
shall likewise be converted, at the Conversion Rate, into fully paid and non-
assessable shares of Common Stock.  Any 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 C Stock shall have been surrendered for
conversion and written notice shall have been

                                     -7-

<PAGE>

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 C Stock shall be treated for all purposes 
as having become the record holder or holders of such shares of Common Stock 
at such time.

         B.  NOTICE TO COMPANY.  In order to convert all or any portion of
its outstanding Series C Stock into shares of Common Stock, the holder of such
Series C Stock shall deliver the shares to be converted to the Company at its
principal office, together with written notice that it elects to convert those
shares of Series C 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 C 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, 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 C Stock to be converted or by his or
her attorney duly authorized in writing.

         C.  DELIVERY OF CERTIFICATE.  As promptly as practicable after the
surrender as hereinabove provided of shares of Series C 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 C Stock (and any accumulated and unpaid dividends thereon) are
entitled to be converted, together with a cash adjustment in respect of any
fraction of a share of Common Stock to which the holder would otherwise be
entitled, and, if less than the entire number of shares of Series C Stock
represented by the certificate or certificates surrendered is to be converted,
a new certificate for the number of shares of Series C Stock not so converted.
So long as any shares of Series C 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 C Stock shall be
made without charge to the holder for any tax in 

                                     -8-

<PAGE>

respect of the issuance of such certificates (other than any transfer tax if 
the shares of Common Stock are to be registered in a name different from that 
of the registered holder of Series C 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 C 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.  ADJUSTMENT TO CONVERSION RATE.  The Conversion Rate and other
terms of conversion shall be subject to adjustment from time to time as
follows:

             (1)  If, at any time or times after issuance of shares of Series C
Stock, the Company shall (x) declare and pay to the holders of Common Stock a
dividend or other distribution payable in shares of Common Stock or
(y) subdivide the outstanding shares of Common Stock into a greater number of
shares of Common Stock or combine the outstanding shares of Common Stock into a
lesser number of shares or issue by reclassification of its shares of Common
Stock any shares of the Company or other property, then in each such case the
Conversion Rate and other terms of conversion in effect immediately prior
thereto shall be adjusted so that the holders of Series C Stock thereafter
surrendered for conversion shall be entitled to receive the number of shares of
Common Stock or other securities or property which such holder would have owned

converted immediately prior to the record date for the determination of
stockholders entitled to receive the dividend or other distribution described
in clause (x) or the happening of the event described in clause (y) on the day
upon which such event becomes effective.

disposition of assets, shares of stock or other securities, property or 
assets of the Company (or the successor, transferee or affiliate of the 
Company) or cash are to be received by or distributed to the holders of 
Common Stock, then the holder of shares of Series C Stock shall have the 
right thereafter to receive, upon conversion of each share of Series C Stock, 
the number of shares of stock or other securities, property or assets of the 
Company (or the successor, transferee or affiliate of the Company), or cash

or disposition of assets by a holder of the number of shares of Common Stock 
into which a share of Series C Stock was convertible immediately prior to 
such event.  The provisions of this subparagraph (2) shall similarly apply to 
successive reorganizations, mergers, consolidations or dispositions of assets.

             (3)  Anything herein to the contrary notwithstanding, no
adjustments pursuant to this Section 6.e shall be made by reason of or in

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 C Stock in accordance with
the provisions of this Section 6.

                                     -10-

<PAGE>

         G.  RETIREMENT OF SHARES.  Any shares of Series C 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.  VOTING RIGHTS.

         A.  GENERAL.  Except as specifically set forth in the DGCL or
provided in the balance of this Section 7, the holders of shares of Series C
Stock shall not be entitled to any voting rights with respect to any matters
voted upon by stockholders.

         B.  VOTING BY CLASS ON CERTAIN MATTERS.  So long as any shares of
Series C 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 votes of
the shares of Series C Stock then outstanding, voting separately as a class,
shall be necessary to validate or effectuate any of the following: (i) the
amendment, alteration or repeal of the Certificate of Incorporation of the
Company so as to affect adversely the powers, preferences or special rights of
such Series C Stock, or (ii) any increase in the number of authorized shares of
Series C Stock.

thirty (30) days' prior notice to the holders of record of the Series C Stock
to be redeemed, given by mail, at a price per share of Series C Stock equal to
the Face Amount thereof plus accumulated and unpaid dividends thereon up to the
date of redemption.  The date of redemption shall be the date fixed therefor in
the notice of redemption.

         B.  PRO RATA REDEMPTION.  If less than all outstanding Series C
Stock is to be redeemed, the redemption may be made either pro rata or by lot
or in some other

<PAGE>

equitable manner as may be prescribed by resolution of the Board.

         C.  NOTICE OF REDEMPTION.  Any notice of redemption mailed to a

of redemption; the number of shares of Series C Stock to be redeemed, and, if
less than all shares of Series C Stock held by such holder are to be redeemed,
the number of such shares to be redeemed from him or her and the fact that a
new certificate or certificates representing any unredeemed shares shall be
issued without cost to such holder; the redemption price applicable to the
shares to be redeemed; the place or places where such shares are to be
surrendered; and that shares to be redeemed may be converted at any time prior
to the close of business on the business day immediately preceding the
redemption date pursuant to Section 6 hereof, giving the then applicable
Conversion Rate.  No defect in any such notice to any holder of Series C Stock
shall affect the validity of the proceedings for the redemption of any other
shares of such Series C Stock.

         D.  EFFECT OF REDEMPTION.  From and after the date of redemption,
all dividends on the Series C Stock called for redemption shall cease to
accumulate and all rights of the holders thereof as stockholders of the
Company, except the right to receive the redemption price, shall terminate.

         E.  RETIREMENT OF SHARES.  Any shares of Series C Stock redeemed
pursuant to the provisions of this Section 8 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.

     9.  NO SINKING FUND.

     No sinking fund shall be established for the retirement or redemption of
shares of Series C Stock.

16, 1996, by and among ALLIANCE IMAGING, INC., a Delaware corporation 
("Parent"), ALLIANCE IMAGING OF PENNSYLVANIA, INC., a Pennsylvania

(collectively, the "Stockholder Consents"), pursuant to which, among other 
things, such stockholder will (a) consent to the terms and conditions hereof, 
(b) join in certain provisions hereof, (c) agree not to sell, transfer or

II.

                         MERGER AND ORGANIZATION

the Pennsylvania Consolidated Statutes and the respective Articles of 
Incorporation and Bylaws of the Constituent Corporations, as soon as 
practicable after the conditions to the Merger set forth in Article 6 hereof

provided that this Agreement has not theretofore been terminated pursuant to 
Article 7 hereof, Parent, Acquisition Sub and Seller shall cause articles of 
merger which conform to the provisions of this Agreement (the "Certificate of 
Merger") to be executed and filed with the Department of State of the 
Commonwealth of Pennsylvania as provided in the Business Corporation Law of

Certificate of Merger with the Department of State of the Commonwealth of 
Pennsylvania (the date and time of such filing and Closing being referred to

of the parties, the "Terminal Date").  

                (7)   FURTHER ASSURANCES.  If at any time after the Effective 
Date, the Surviving Corporation shall consider or be advised that any deeds, 
bills of sale, assignments or assurances or any other acts or things are 
necessary, desirable or proper (a) to vest, perfect or confirm, of record or 
otherwise, in the Surviving Corporation, its right, title or interest in, to 
or under any of the rights, properties or assets of the Constituent 
Corporations acquired or to be acquired as a result of the Merger, or (b) 
otherwise to carry out the purposes of this Agreement, the Surviving 
Corporation and its officers and directors or their designees shall be

result of the Merger and otherwise to carry out the purposes of this 
Agreement.  

III.

                        CONVERSION OF SHARES
                       ON THE EFFECTIVE DATE

    A.    CONVERSION OF SHARES IN THE MERGER.    Each share of Common Stock, 
no par value, of Seller ("Seller Common Stock") that is issued and 
outstanding immediately prior to the Effective Date shall, by virtue of the 
Merger, be converted into the right to receive the Securities and Cash 
Consideration or the Cash Only Consideration, at the election of each holder 
of record of Seller Common Stock (subject to Section 2.4 below) as indicated 
in such holder's Stockholder Consent or by separate letter of instruction.  
"Cash Only Consideration" means Ten Dollars ($10.00) in cash per share of 
Seller Common Stock.  "Securities and Cash Consideration" means, per share of 
Seller Common Stock, a combination of (a) Eight Dollars ($8.00) in cash, (b) 
 .04 shares of Parent's Series C Cumulative Convertible Redeemable Preferred 
Stock, such stock to have rights, preferences and privileges and to be 
subject to restrictions substantially as indicated in the form of designation 
attached hereto as Exhibit 2.1A (the "Parent Preferred Stock"), and (c) a 
warrant to acquire one (1) share of Parent Common Stock for $5.00 in cash, 
such warrant to be evidenced by a Warrant Certificate substantially in the 
form attached hereto as Exhibit 2.1B (the "Parent Warrants"; together, the 
Parent Preferred Stock and the Parent Warrants are sometimes referred to 
herein as the "Parent Securities").

    B.    CANCELLATION OF SHARES OF SELLER COMMON STOCK. Notwithstanding 
anything in Section 2.1 to the contrary, each of the shares of Seller Common 
Stock held by Seller as treasury shares or which is owned by Parent or 
Acquisition Sub, if any, immediately prior to the Effective Date shall be 
cancelled.  

    C.    CONVERSION OF SHARES OF ACQUISITION SUB.  The shares of the capital 
stock of Acquisition Sub that are issued and outstanding immediately prior to 
the Effective Date shall, by virtue of the Merger and without any action of 
the part of 

                                    -5-

<PAGE>


the holder thereof, be converted into One Thousand (1,000) newly issued 
shares of capital stock of the Surviving Corporation.

    D.    NO FURTHER TRANSFERS OF STOCK.  On the date hereof, the stock 
transfer books of Seller shall be closed and, unless this Agreement has 
theretofore been terminated as provided herein, no transfers of shares of 
Seller Common Stock shall be made thereafter, nor shall any such attempted 
transfers be recognized by Seller on the stock transfer books or otherwise.  
If, after the Effective Date, certificates representing former shares of 
Seller Common Stock are properly presented to the Surviving Corporation, they 
shall be exchanged for the appropriate Securities and Cash Consideration or 
Cash Only Consideration and cancelled as provided in Section 2.5 below; 
provided, however, that notwithstanding anything herein to the contrary any 
such certificates surrendered after sixty (60) days following the Effective 
Date will be exchanged for the Cash Only Consideration, and the holder 
thereof will not have an election to select the Securities and Cash 
Consideration.

                                    -6-

<PAGE>

     E.  SURRENDER OF CERTIFICATES.

         (1)  On the Effective Date, each holder of former shares of Seller 
Common Stock (other than shares, if any, held by Parent or Acquisition Sub) 
who has executed a Stockholder Consent, shall surrender all certificates 
representing such shares to the Surviving Corporation for cancellation. All 
such shares shall be delivered to the  Surviving Corporation free and clear 
of all liens, claims and encumbrances of any party and of any nature 
whatsoever. Upon surrender of such certificates to the Surviving Corporation, 
each such holder of former shares of Seller Common Stock shall be entitled to 
receive in exchange therefor the applicable Securities and Cash Consideration 
or Cash Only Consideration in the form indicated in Section 2.1 above. No 
interest will accrue or be paid with respect to any Merger consideration, 
either with respect to the period from the date hereof to the  Effective Date 
or any period after the Effective Date. Until certificates representing 
former shares of Seller Common Stock are surrendered as provided herein, such 
certificates shall represent only the right to receive the applicable Merger 
consideration, and shall not represent any right, title or interest in or to 
the capital stock of Seller, either of the Constituent Corporations or the 
Surviving Corporation.

         (2)  Seller shall use its best efforts to advise Parent and 
Acquisition Sub, on a date that is at least five (5) business days prior to 
the Closing, of the names in which certificates for new Parent Securities to 
be issued in the Merger shall be issued and the names in which checks for the 
Cash Only Consideration shall be drawn. If any such issuance or payment is to 
be made in a name other than that of the registered holder of the former 
Seller Common Stock being converted in the Merger, then it shall be a 
condition of the issuance of the corresponding Parent Securities or payment 
of Cash Only Consideration that the holder of the former Seller Common Stock 
establish to the satisfaction of the Surviving Corporation that no transfer 
or other tax is payable by reason of such issuance or payment, or that all 
such taxes have been paid.


                                    -7-

IV.

                          ADDITIONAL AGREEMENTS IN
                         CONNECTION WITH THE MERGER

     A.  SELLER STOCKHOLDER APPROVAL.

         3.1.1  STOCKHOLDER APPROVAL. Between the date hereof and the 
Closing, Seller shall, in accordance with applicable requirements of the 
Pennsylvania Consolidated Statutes and any other applicable law, and its 
Articles of Incorporation and Bylaws, duly give notice of, and duly call, an 
annual or a special meeting of the stockholders of Seller to be held at the 
earliest practicable date for the purpose of voting on and approving this 
Agreement and the Merger in accordance with the requirements of the 
Pennsylvania Consolidated Statutes and any other applicable law. In 
connection with such annual or special meeting (or, as provided in the next 
sentence, written consent of stockholders), the Board of Directors of Seller 
shall recommend that all of Seller's stockholders approve such matters and 
shall otherwise use its best efforts to obtain such approval. Notwithstanding 
the first sentence of this Section, subject to applicable provisions of the 
Pennsylvania Consolidated Statutes and any other applicable law, Seller may 
dispense with the annual or special meeting referred to above and, in lieu of 
holding such a meeting, may provide for stockholder consent of this Agreement 
and the Merger pursuant a written consent of stockholders. Whether the 
approval of Seller's stockholders is obtained pursuant to a meeting or 
written consent as hereinabove provided, Seller agrees to use, in addition to 
any solicitation materials prepared by Seller (copies of which will be 
provided to Parent), the Private Placement Memorandum (as hereinafter 
defined) in connection with the solicitation of approval of its stockholders 
of this Agreement and the Merger.

         3.1.2  PRIVATE PLACEMENT MEMORANDUM. Promptly after the date hereof, 
Parent shall prepare a Private Placement Memorandum (the "Private Placement 
Memorandum") covering the issuance of shares of Parent Securities pursuant to 
the Merger as provided in this Agreement. Prior to finalizing the Private 
Placement Memorandum, Parent will 


                                    -8-


<PAGE>


provide a copy thereof to the Board of Directors of Seller to allow such 
Board to provide input concerning the substance thereof, for Parent's 
reasonable consideration. Parent represents and warrants to Seller, and 
Seller represents and warrants to Parent and Acquisition Sub, that none of 
the information with respect to it or them (in the case of Seller, including 
its directors, officers and stockholders and their respective affiliates) 
that is included in the Private Placement Memorandum will contain any untrue 
statement of a material fact or omit to state any material fact required to 
be stated therein or necessary in order to make the statements therein, in 
light of the circumstances under which they are made, not misleading.

         3.1.3  STATE SECURITIES APPROVALS. Parent, Acquisition Sub and 
Seller shall cooperate with one another in taking all such action as may be 
required under state blue-sky or securities laws in connection with the 
transactions contemplated by this Agreement.

     B.  NOTICE OF PROPOSALS; NO SHOP. If after the making of this Agreement 
any person or entity extends to Seller any offer, or Seller becomes aware of 
any offer, to acquire any shares of any capital stock of Seller or any assets 
or properties of Seller, directly or indirectly and regardless of the form of 
the transaction, or Seller becomes aware that any person or entity is seeking 
to conduct any discussions with respect to any such matters, then in each 
such case Seller shall promptly notify Parent and Acquisition Sub of such 
information, including the identity of such person or entity. Unless this 
Agreement has theretofore been terminated in accordance with Article 7 
hereof, Seller shall not, and shall not permit any of its officers, 
directors, employees, agents or representatives (including, without 
limitation, investment bankers, attorneys and accountants) to, directly or 
indirectly, initiate, solicit, encourage (including, without limitation, by 
way of furnishing any non-public information concerning Seller) or conduct or 
participate in any discussions with respect to any matter described in the 
preceding sentence.

     C.  REASONABLE EFFORTS. Subject to the terms and conditions hereof, each 
of the parties hereto agrees to use all its reasonable efforts to take, or 
cause to be taken, to 


                                    -9-


<PAGE>


do, or cause to be done, and to assist and cooperate with the other parties 
hereto in doing, all things necessary, proper or advisable under applicable 
laws and regulations to consummate and make effective, as soon as 
practicable, the transactions contemplated by this Agreement. Such actions 
shall include, without limitation, (a) using reasonable efforts to obtain any 
consents, amendments to or waivers under the terms of any borrowing 
arrangements of Parent, Acquisition Sub and Seller that are required or 
advisable as a result of the transactions contemplated by this Agreement, (b) 
using reasonable efforts to obtain consents, amendments to or waivers under 
the terms of Seller's other material contracts and arrangements that are 
required or advisable as a result of the transactions contemplated by this 
Agreement, and (c) using reasonable efforts to defend any lawsuits or other 
legal proceedings, whether judicial or administrative and whether brought 
derivatively or on behalf of third parties (including governmental agencies 
or officials), challenging this Agreement or the consummation of the 
transactions contemplated hereby. Subject to the terms and conditions hereof, 
each of the parties hereto agrees to use all its reasonable efforts to take, 
or cause to be taken, all actions and to do, or cause to be done, all things

do any of the things described in any of clauses (i) through (vii).

     E.  NOTICE OF ACTIONS AND PROCEEDINGS. Seller shall promptly notify 
Parent and Acquisition Sub of any claims, actions, proceedings or 
investigations commenced or, to the best of its knowledge, threatened, 
involving or affecting Seller or any of its properties or assets, or, to the 
best of its knowledge, against any employee, consultant, director, officer or 
stockholder of Seller in his, her or its capacity as such, which (a) if 
decided adversely to Seller or such other person, might reasonably be 
expected to materially and adversely affect the financial condition, 
business, properties or results of operations of Seller, or (b) relates to 
the consummation of the Merger or any of the other transactions or 
obligations contemplated hereby.

     F.  NOTIFICATION OF CERTAIN OTHER MATTERS. Seller shall give prompt

prompt notice to the other parties or party of any materially adverse change 
in, or any facts or circumstances that arise or become evident after the date

information concerning the business and properties of Seller as Parent, 
Acquisition Sub or their Representatives may request. Parent and Acquisition 
Sub will, and will cause their Representatives to, hold in confidence all 
confidential information, and will not use any such confidential information 
except in connection with the transactions contemplated hereby, until such 
time as (a) such information is otherwise publicly available, (b) they are 
advised by counsel that any such information is required by law or 
governmental process to be disclosed or (c) such information becomes known to 
any of them through a third party that is not known to them to be under a 
duty of confidentiality to Seller. In the event of the termination of this 
Agreement for any reason, Parent and Acquisition Sub will, and will cause 
their Representatives to, deliver to Seller all documents, work papers and 
other materials obtained by them or on their behalf as a result of this 
Agreement or in connection herewith, whether so obtained before or after the 
execution hereof.

     H.  FEES AND EXPENSES. If the Merger is completed, Parent will cause the 
Surviving Corporation to pay Seller's fees and expenses (including, without 
limitation, all fees and expenses of attorneys, accountants and other agents

to make disclosure shall nonetheless reasonably attempt to obtain approval 
of the other party to the proposed disclosure).

V.

                         REPRESENTATIONS AND WARRANTIES
                                   OF SELLER

     As an inducement to Parent and Acquisition Sub to enter into this 
Agreement, Seller represents and warrants to Parent and Acquisition Sub as 
follows:


                                    -14-


<PAGE>

    A.    EXISTENCE AND RIGHTS; COMPLIANCE WITH LAWS. 

           1.  EXISTENCE AND RIGHTS.  Seller (i) is a corporation duly 
organized and validly existing in good standing under the laws of the 
Commonwealth of Pennsylvania without limit as to the duration of its 
existence; (ii) has the corporate power and adequate authority, rights and 
franchises to own its properties and to carry on its business as now 
conducted and to make and carry out this Agreement; and (iii) is duly 
qualified and in good standing in each jurisdiction in which its owned or 
leased properties or the character of its business makes such qualification 
necessary. The copies of the Articles of Incorporation and Bylaws of Seller 
previously delivered to Parent and Acquisition Sub remain complete and in 
full force.  Schedule 4.1.1 hereto contains a complete list of all 
Certificates of Need and similar governmental approvals held by Seller or 
under which Seller operates any part of its business, in the latter case 
including the identity of the holder of such certificate or approval, and in 
each case indicating the status thereof and whether the approval is being 
actively used.  All such certificates and approvals are valid and in full 
force and effect.

           2.  COMPLIANCE WITH LAWS.  Seller's business has been and is being 
conducted in all material respects in accordance with all applicable federal, 
state and local laws and regulations and rules and regulations of all 
applicable private third party insurers and reimbursers of health care costs 
and expenses, including, without limitation, such laws, regulations and rules 
as relate to the practice of medicine and the provision of medical diagnostic 
mobile imaging services and otherwise. 

    B.    STOCK.  Seller's authorized capital stock consists of 100,000 
shares of a single class of stock, the Seller Common Stock, of which 100,000 
have been duly authorized and are validly issued and outstanding as of the 
date hereof and will be duly authorized and validly issued and outstanding as 
of the Effective Date.  All shares of such outstanding capital stock are 
fully paid and non-assessable and were issued in compliance with all 
applicable state and federal securities laws and other applicable laws.  
There are no outstanding securities convertible into, or options, warrants, 
rights, 

                                   -15-

<PAGE>

calls or other commitments of any nature relating to, the issuance of any 
securities of Seller.  Schedule 4.2 contains a true and correct list showing 
the shareholders of record of Seller as of the date hereof, the number of 
shares of Seller Common Stock owned of record by each such shareholder and, 
to the best of Seller's knowledge, the state of residence of each such 
shareholder.

    C.    AGREEMENT AUTHORIZED.  Except for obtaining stockholder approval as 
elsewhere provided in this Agreement, the execution, delivery and performance 
of this Agreement by Seller have been duly and validly authorized by all 
necessary corporate action (including, without limitation, approval by the 
Board of Directors and stockholders of Seller in accordance with applicable 
law) on the part of Seller and do not require notice to, or the consent or 
approval of, any governmental body or other regulatory authority.  This 
Agreement is a legal, valid and binding obligation of Seller, enforceable 
against Seller in accordance with its terms.  

    D.    SUBSIDIARIES.  Seller has no subsidiaries and no equity interests 
in any other entities nor any obligation, option or right to acquire any such 
interest, excepting solely six (6) limited partnership units of Western 
Pennsylvania Eye Laser Associates, L.P., an entity that operates a Summit eye 
laser in Pittsburgh, Pennsylvania.  Seller has supplied to Parent a copy of 
the private placement memorandum relating to such investment.

    E.    CONTRACTS.  All Material Contracts (or copies thereof) to which 
Seller is a party or by which it or any of its assets or properties are bound 
have been previously delivered to Parent or its counsel by Seller.  For the 
purpose of this Section 4.5, the term "Material Contracts" means (a) all 
contracts or commitments arising out of the ordinary and usual course of 
business; (b) all contracts or commitments involving an obligation which 
cannot or in reasonable probability will not be performed or terminated 
within six (6) months from the date hereof or providing for termination only 
upon the payment of a penalty or the equivalent thereof; (c) all contracts or 
commitments affecting ownership of, title to, use of, or any interest in real 
estate; (d) all bonuses, incentive compensation, pension, group insurance or 
employee welfare plans of any nature whatsoever; (e) all collective 

                                   -16-

<PAGE>

bargaining agreements or other contracts or commitments to or with any labor 
unions or other employee representatives or groups of employees; (f) 
employment contracts and all other contracts, agreements or commitments to or 
with individual employees or agents extending for a period of more than three 
(3) months from the date hereof or providing for earlier termination only 
upon the payment of a penalty or the equivalent thereof; (g) all other 
contracts or commitments providing for payments based in any manner upon the 
sales, purchases or profits of Seller; (h) all contracts or commitments, 
whether in the ordinary course of business or not, which involve future 
payments, performance of services or delivery of goods and/or materials, to 
or by Seller of an aggregate amount or value in excess of Twenty-Five 
Thousand Dollars ($25,000), including, without limitation, and whether or not 
meeting that numerical standard all such contracts or commitments relating to 
(x) the purchase, lease or other acquisition or use of medical diagnostic 
imaging equipment, or (y) the provision of equipment or services to health 
care providers or other customers or clients of Seller (in the case of this 
clause (4), Schedule 4.5 attached hereto listing all such Material Contracts 
and indicating which of them were entered into after February 1, 1996, if 
any); and (i) all patent licensing agreements and all other agreements and 
commitments with respect to patents, patent applications, trademarks, trade 
names, service marks, inventions, technical assistance, know-how, special 
processes, copyrights or other like items. There is no material default in 
any obligation to be performed by Seller under any Material Contract and 
Seller has not waived any material right under any Material Contract.  Seller 
does not have any outstanding contract, commitment or undertaking which will 
result in any material loss upon completion or performance thereof after 
allowance for general and administrative selling and distribution expenses or 
will be unreasonably adverse, onerous or harmful to its assets, business, 
operation or financial condition.  Seller is not in default nor is there any 
basis for any claim of default under any contract made or obligation owed to 
it, and Seller has not waived any material right under any such contract or 
obligation, except for defaults and waivers which are not material to the 
financial condition, properties, business or results of operations of Seller. 
Seller (including its employees) is not restricted by agreement from 
carrying on its business anywhere in the United States.

                                   -17-

<PAGE>

    F.    NO CONFLICT.  The execution, delivery and perform-ance of this 
Agreement will not (i) breach or constitute grounds for the occurrence or 
declaration of an acceleration of payment or a default or a right of 
termination under any agreement, indenture, undertaking or other instrument 
to which Seller is a party or by which it or any of its properties may be 
bound or affected; (ii) violate any provision of law or any regulation or any 
order, judgment or decree of any court or other agency of government, the 
violation of which could have a material adverse effect on the financial 
condition, properties, business or results of operations of Seller; (iii) 
result in a breach of, conflict with, or give to others any rights of 
termination, amendment, or cancellation of, any permit, franchise or license 
to which Seller is a party or by which it or any of its properties may be 
bound or affected or which is otherwise material to the operation of its 
business; (iv) violate any provision of the Articles of Incorporation or 
Bylaws of Seller; or (v) result in the creation or imposition of (or the 
obligation to create or impose) any lien, charge or encumbrance on, or 
security interest in or on, any of its properties.  Without limiting the 
generality of the foregoing, the execution, delivery and performance of this 
Agreement does not and will not require the consent of any third party under 
any Material Contract except as set forth on Schedule 4.6 hereto.

    G.    LITIGATION.  Except as set forth on Schedule 4.7, there is no 
litigation, investigation, arbitration or other proceedings (formal or 
informal) pending or, to the best knowledge of Seller, threatened against or 
affecting it or its properties; nor does Seller know of any reasonable basis 
for any litigation, investigation, arbitration or other pro-ceedings (formal 
or informal), the results of which could have a material adverse effect on 
its financial condition, properties, business or results of operations.  
Seller is not in default with respect to any order, writ, injunction, decree 
or demand of any court or other governmental or regulatory authority.  

    H.    FINANCIAL CONDITION.  The balance sheets of Seller as of June 30, 
1995, February 29, 1996 and March 31, 1996, and the related profit and loss 
and cash flow statements for the periods ended on those dates, and the 
related notes for such 

                                   -18-

<PAGE>


financial statements, copies of which have heretofore been or will be 
delivered to Parent and Acquisition Sub by Seller, and all other historical 
financial statements and data submitted in writing by Seller to Parent and 
Acquisition Sub at any time (collectively, the "Financial Statements"), are 
or, when delivered, will be true and correct as of the respective dates 
thereof, and the Financial Statements truly present and will truly present 
the financial condition of Seller as at the respective dates thereof and the 
results of the operations of Seller for the respective periods covered 
thereby, and have been and will have been prepared in all material respects 
in accordance with generally accepted accounting principles on a basis 
consistently maintained ("GAAP"); provided, however, with respect to 
technical GAAP issues relating to methods of depreciation, calculation of 
depreciation, capitalization of leases, carrying value of intangible assets 
and capitalization of equipment, Seller represents to the best of its 
knowledge that the Financial Statements have been and will have been prepared 
in all material respects in accordance with GAAP. Seller has no knowledge of 
any liabilities or guarantees, matured or unmatured, contingent or otherwise, 
as of the respective dates of the Financial Statements not accurately 
reflected in the Financial Statements, and none have arisen since those times 
except in the ordinary and usual course of business.  With respect to 
Seller's contracts, commitments and loss contingencies, the Financial 
Statements contain and reflect adequate reserves.  In addition to the 
Financial Statements, Seller has provided Parent and Acquisition Sub with 
financial projections relating to its 1996 fiscal year. Except as reflected 
in the notes or assumptions to the latest iteration of such projections 
delivered prior to the date hereof, Seller is not aware of any facts or 
contingencies that cast significant doubt on Seller's ability to achieve the 
financial results reflected in such projections nor does Seller otherwise 
have a basis for believing that the financial results that are reflected in 
such projections are not reasonably achievable.  As of March 31, 1996, there 
were no obligations or liabilities of Seller accrued and owing (or which 
should have been shown on Seller's financial statements as accrued and owing) 
other than those set forth on Schedule 4.8 (which Schedule provides a 
detailed listing of all such obligations and liabilities).

                                   -19-

<PAGE>

    I.    ACCOUNTANTS INDEPENDENT; BOOKS AND RECORDS.  To Seller's knowledge, 
the accountants who examined and reported on the Financial Statements, as 
applicable, are, with respect to Seller, independent certified public 
accountants within the meaning of the professional rules of the American 
Institute of Certified Public Accountants.  Seller maintains a system of 
internal accounting control sufficient to provide reasonable assurances that 
(i) transactions are executed in accordance with management's general or 
specific authorization, (ii) transactions are recorded as necessary to permit 
preparation of financial statements in conformity with GAAP, (iii) access to 
assets is permitted only in accordance with management's general or specific 
authorization, and (iv) the recorded accounting for assets is compared with 
the existing assets at reasonable intervals and appropriate action is taken 
with respect to any differences.  

    J.   NO SUBSEQUENT CHANGES.  Except as contemplated in this Agreement or 
reflected in any Schedule attached hereto, since the respective dates of the 
Financial Statements, (i) there have been no material adverse changes 
(whether by sale, destruction, pledge, lease or otherwise and whether or not 
covered by insurance) in the assets (including licenses, permits and 
franchises), liabilities or financial condition of Seller, and (ii) Seller 
has not entered into any commitments, contracts or transactions not reflected 
in the Financial Statements, as required in accordance with GAAP, except as 
specified on Schedule 4.10.  Since the respective dates of the Financial 
Statements, (a) Seller has not, directly or indirectly, paid, declared, or 
set aside any dividends or distributions with respect to, nor repurchased, 
any of its capital stock or securities of any class, and (b) to the knowledge 
of Seller, no events have occurred which have had or can reasonably be 
expected to have a material adverse effect on the financial condition, 
properties, business, results of operations or prospects of Seller.  Since 
December 31, 1995, each of Mark J. Graham and Albert F. Calfo, II has earned 
salary (including all cash compensation) at the rate of $122,000 per year and 
neither of them has received any dividend or other distribution on Seller 
Common Stock or any similar payment or distribution.  No later than the 
Closing, Seller shall have taken steps to terminate (without any cost to 
Seller) the existing employment agreements with each of Mr. Graham and Mr. 
Calfo, such agreements to be replaced by new 

                                   -20-

<PAGE>

employment agreements between each of Mr. Graham and Mr. Calfo, on the one 
hand, and the Parent, on the other.

    K.   TITLE TO AND CONDITION OF ASSETS.  Schedule 4.11 sets forth all 
interests in real property held by Seller, including all leases of real 
property.  Seller has good, clear and marketable title to its assets 
(including, without limitation, those shown in the Financial Statements, 
except as subsequently sold in the ordinary course of business and listed on 
Schedule 4.11 hereto) and the same are not subject to any mortgages, deeds of 
trust, pledges, security interests, leases, licenses or other encumbrances 
other than indicated in the Financial Statements or listed on Schedule 4.11 
hereto. Schedule 4.11 includes a schedule of all bank indebtedness and 
related liens currently in effect.  None of the assets of Seller, tangible or 
intangible, are located outside of the United States and Seller does not own 
or hold any stock or securities, or receivables from or claims against 
foreign entities.  All of the assets and currently used properties of Seller 
are in good operating condition, ordinary wear and tear excepted.  

    L.   ENVIRONMENTAL MATTERS.  Except as set forth on Schedule 4.12, Seller 
has all permits, licenses and other authorizations required for the operation 
of its business (as presently conducted) under federal, state, and local laws 
relating to pollution, protection of the environment and the storage, 
presence and discharge of chemicals and other substances (collectively, 
"Environmental Laws").  There is no civil, criminal or administrative action, 
suit, demand, claim, hearing, notice of violation, investigation, proceeding, 
notice or demand letter under the Environmental Laws pending, or to the best 
knowledge of Seller threatened, against Seller or any of its owned or leased 
real or personal property. Neither Seller nor, to the best knowledge of 
Seller, any other person or entity has placed, stored, buried, dumped or 
disposed of any regulated or prohibited substances or any materials produced 
by, or resulting from, any business, commercial or industrial activities, 
operations or processes on, beneath, or adjacent to any owned or leased real 
property of Seller, except to the extent handled or reported and remedied in 
all material respects in accordance with applicable Environmental Laws.  To 
the best knowledge of Seller, no employee of Seller has been exposed in the 
course 

                                   -21-

<PAGE>

of his or her employment with Seller to any regulated or prohibited 
substances or any materials produced or used by Seller in any manner that 
could give rise to any material liability under any applicable Environmental 
Law against Seller or its properties.  Seller has not received any notice 
from any governmental agency or private or public entity advising Seller that 
it is responsible or potentially responsible for actual or potential response 
costs with respect to a release, a threatened release or clean-up of 
materials (including hazardous substances as defined in any Environmental 
Laws) nor is Seller aware of any facts that might reasonably be expected to 
give rise to any such notice.

    M.   TAX STATUS.

           1.  RETURNS FILED.  Seller has timely filed all Tax Returns 
required to have been filed by it and has paid or accrued all Taxes due to 
any taxing authority with respect to all taxing periods ending on or prior to 
the date hereof; and all such Tax Returns are true, correct and complete in 
all material respects.  The Financial Statements include an adequate reserve 
for all Taxes not yet due or with respect to which Tax Returns, as of the 
Closing, are not required to have been filed, in each case to reflect the 
operations of Seller through the Closing.  There is no pending Tax audit by a 
governmental authority against or affecting Seller.  Seller has (or before 
the Closing will have) filed its federal and state income Tax Returns 
relating to its fiscal year ended June 30, 1995 and paid all Taxes shown as 
payable thereon. Seller has (or will) provide copies of such Tax Returns to 
Parent.  

           2.  COLLECTIONS AND PAYMENTS.  (a) All amounts that are required 
to be collected or withheld by Seller have been duly collected or withheld, 
and (b) all such amounts that are required to be remitted to any taxing 
authority (including license and other similar fees payable to the Department 
of Motor Vehicles and other governmental agencies) have been duly remitted.

           For purposes of this Agreement, "Taxes" means all taxes imposed of 
any nature including federal, state, commonwealth, local or foreign net 
income tax, alternative or add-on minimum tax, profits or excess profits tax, 
franchise 

                                   -22-

related tax (including employee withholding and employer payroll tax, FICA 
and FUTA), real and personal property tax or ad valorem tax, sales or use 
tax, excise tax, stamp tax or duty, any withholding or back up withholding 
tax, value added tax, severance tax, prohibited transaction tax, premiums 
tax, occupation tax, together with any interest or any penalty, in addition 
to any tax or additional amount imposed by any governmental authority 
(domestic or foreign) responsible for the imposition of such tax.  "Tax 
Return" means all returns, reports, forms or other information required to be 
filed with respect to any Taxes.

    N.   MARKS.  Seller owns or has the right to use its corporate name in 
all jurisdictions in which the business of Seller is conducted as of the date 
hereof.  Seller is not infringing on any trademark, trade name, service mark, 
copyright, patent, or license in the operation of its business, and Seller 
does not know of any third party who has asserted any claim concerning such 
an infringement.  

    O.   ERISA.  Neither Seller nor any affiliated company under common 
control of or with Seller within the meaning of the Employee Retirement 
Income Security Act of 1974, as amended ("ERISA"), maintains on the date 
hereof any employee benefit plan subject to the provisions of ERISA, nor 
contributes to any such plan (including any multi-employer plan) on behalf of 
its employees.  Seller does not have any unfunded pension, profit sharing or 
deferred compensation plans or arrangements.  Seller has complied in all 
respects with, and is currently in compliance with, the continuation of 
benefits provisions applicable to former employees under ERISA and similar 
federal and state laws and regulations.

    P.   INSURANCE.  Schedule 4.16 to this Agreement sets forth all insurance 
policies of Seller that are currently in effect, including in each case the 
type and amount of coverage and carrier.  All of the material properties and 
assets of Seller which are of an insurable character are insured against loss

                    REPRESENTATIONS AND WARRANTIES
                    OF PARENT AND ACQUISITION SUB 

    As an inducement to Seller to enter into this Agreement, Parent and 
Acquisition Sub, jointly and severally, represent and warrant to Seller as 
follows: 

    A.   EXISTENCE AND RIGHTS; COMPLIANCE WITH LAWS.  

           1.  EXISTENCE AND RIGHTS.  Parent is a corporation duly organized 
and validly existing in good standing under the laws of Delaware without 
limit as to the duration of its existence.  Acquisition Sub is a corporation 
duly organized and validly existing in good standing under the laws of the 
Commonwealth of Pennsylvania without limit as to the duration of its 
existence.  Acquisition Sub is a direct wholly-owned subsidiary of Parent.  
Each of Parent and Acquisition Sub (i) has the corporate power and adequate 
authority, rights and franchises to own its properties and to carry on its 
business as now conducted and to make and carry out this Agreement, and (ii) 
is duly qualified and in good standing in each jurisdiction in which its 
owned or leased properties or the character of its business makes such 
qualification necessary, or, if not so qualified, the failure to so qualify 
will not have a material adverse effect upon the consolidated financial 
condition of Parent. 

           2.  COMPLIANCE WITH LAWS.  Parent's business has been and is being 
conducted in all material respects in accordance with all applicable federal, 
state and local laws and regulations and rules and regulations of all 
applicable private third party insurers and reimbursers of health care costs 
and expenses, including, without limitation, such laws, regulations and rules 
as relate to the practice of medicine and the provision of medical diagnostic 
imaging services and otherwise. 

    B.    AGREEMENT AUTHORIZED.  The execution, delivery and performance of 
this Agreement by each of Parent and Acquisition Sub have been duly and 
validly authorized by all necessary corporate action on the part of each of 
them and do not require notice to, or the consent or approval of, any 

                                   -26-

<PAGE>

governmental body or other regulatory authority.  This Agreement is a legal, 
valid and binding obligation of each of Parent and Acquisition Sub, 
enforceable against each of them in accordance with its terms.  

    C.    NO CONFLICT.  The execution, delivery and performance of this 
Agreement will not (i) except as will be cured, waived or consented to 
pursuant to the Parent Debt Consents referred to in Section 6.1, breach or 
constitute grounds for the occurrence or declaration of a default under any 
agreement, indenture, undertaking or other instrument to Parent or 
Acquisition Sub is a party or by which it or any of its properties may be 
bound of affected, except any such breach or default which would not have a 
material adverse effect on the ability of Parent and Acquisition Sub to 
consummate the transactions contemplated by this Agreement; (ii) violate any 
provision of law or any regulation or any order, judgment or decree of any 
court of other agency of government, the violation of which could have a 
material adverse effect on the ability of Parent and Acquisition Sub to 
consummate the transactions contemplated by this Agreement; or (iii) violate 
any provision of the Certificate of Incorporation or Bylaws of Parent or the 
Articles of Incorporation or Bylaws of Acquisition Sub.  

    D.    LITIGATION.  There is no litigation, investigation, arbitration or 
other proceedings (formal or informal) pending or, to the best knowledge of 
Parent, threatened against or affecting it or its properties; nor does Parent 
know of any reasonable basis for any litigation, investigation, arbitration 
or other proceedings (formal or informal), in the case of any matter referred 
to in this Section 5.4 the results of which could have a material adverse 
effect on its financial condition, properties, business or results of 
operations.  Parent is not in default with respect to any order, writ, 
injunction, decree or demand of any court or other governmental or regulatory 
authority.  

    E.    FINANCIAL STATEMENTS.  The consolidated financial statements of 
Parent included in the Private Placement Memorandum (collectively, the 
"Parent Financial Statements"), are true and correct as of the respective 
dates thereof, and the Parent Financial Statements fairly present the 
consolidated financial condition of Parent as at the 

                                   -27-

<PAGE>

respective dates thereof and the consolidated results of the operations of 
Parent for the respective periods covered thereby, and have been prepared in 
accordance with GAAP. Parent has no knowledge of any liabilities or 
guarantees, matured or unmatured, contingent or otherwise, as of the 
respective dates of the Parent Financial Statements not accurately reflected 
in the Parent Financial Statements, and none have arisen since those times 
except in the ordinary and usual course of business.  With respect to 
Parent's contracts, commitments and loss contingencies, the Parent Financial 
Statements contain and reflect adequate reserves.

    F.    SHARES DULY AUTHORIZED.  The shares of Parent Preferred Stock to be 
issued in the Merger will, when issued pursuant to the terms and conditions 
of this Agreement, and the shares of Parent Common Stock issuable upon 
exercise of the Parent Warrants will, when issued pursuant to the terms and 
conditions of the Parent Warrants, be duly and validly issued, fully paid and 
non-assessable.

    G.    NO FINDER'S FEES.  None of Parent, Acquisition Sub nor any of their 
respective officers, directors, agents or employees have employed or incurred 
any liability to any broker, finder or agent for any brokerage fees, finder's 
fees, commissions or other amounts with respect to the transactions 
contemplated by this Agreement, and Parent and Acquisition Sub agree to hold 
Seller harmless from and against damages or cost incurred by reason of any 
such assertions.

                               JOINDER AND CONSENT


     THIS JOINDER AND CONSENT (the "Agreement") is dated as of April 16, 1996,
by and among ALLIANCE IMAGING, INC., a Delaware corporation ("Parent"), ALLIANCE
IMAGING OF PENNSYLVANIA, INC., a Pennsylvania corporation ("Acquisition Sub"),
and ___________________________________, an individual ("Stockholder").

                               W I T N E S S E T H

     A.   Parent, Acquisition Sub and Royal Medical Health Services Inc., a
Pennsylvania corporation ("Seller"), are parties to an Agreement and Plan of
Merger dated as of April 16, 1996 (the "Merger Agreement"), pursuant to which,
among other things, it is contemplated that Acquisition Sub will be merged with
and into Seller (the "Merger") and that all of the shares of Seller's capital
stock issued and outstanding will be converted into the right to receive either
the Cash Only Consideration or the Securities and Cash Consideration (both as
defined in and subject to the terms of the Merger Agreement).  A copy of the
Merger Agreement is attached hereto as Exhibit A.

     B.   Stockholder is the record, legal and beneficial owner of _________
shares (approximately ___% of the issued and outstanding capital stock of Seller
as of the date hereof) (the "Stockholder Shares") of the Common Stock, no par
value, of Seller ("Seller Common Stock").  Stockholder has approved of and
consented to the Merger Agreement and the Merger and the other transactions
contemplated by the Merger Agreement.  As a stockholder of Seller, Stockholder
will derive significant benefits from the closing of such transactions.

     C.   The execution and delivery of this Agreement by Stockholder is a
condition to the obligations of Parent and Acquisition Sub under the Merger
Agreement.  In order to induce Parent and Acquisition Sub to complete the Merger
and the other transactions contemplated by the Merger Agreement and to satisfy
such condition, Stockholder has agreed to the provisions herein.

<PAGE>

     NOW, THEREFORE, in consideration of the mutual covenants, agreements,
representations and warranties contained herein and, in the case of Parent and
Acquisition Sub, in the Merger Agreement, Parent, Acquisition Sub and
Stockholder agree as follows:

     II.   REPRESENTATIONS AND WARRANTIES.  Stockholder hereby represents and
warrants to Parent and Acquisition Sub as follows:  

                                     -2-

<PAGE>

          A.  OWNERSHIP OF SHARES.  Stockholder is the record, legal and
beneficial owner of all of the Stockholder Shares referred to in Recital B
above, and no other person or entity has any right, title or interest in or to
any of such shares.  Stockholder does not have any option, warrant or other
right to acquire any shares of capital stock of Seller.  At the Closing (as
defined in the Merger Agreement), in accordance with Section 2.5(i) of the
Merger Agreement, Stockholder will deliver to the Surviving Corporation (as
defined in the Merger Agreement) for cancellation all certificates representing
the Stockholder Shares, free and clear of all liens, claims and encumbrances of
any party and of any nature whatsoever.  

          B.  RESALE.  As of the date hereof and the Closing, Stockholder does
not have and will not have a present plan or intention of disposing of any
Parent Securities (as defined in the Merger Agreement) acquired pursuant to the
Merger, if any.  Assuming completion of the Merger, Stockholder will acquire
such Parent Securities for investment purposes and not for resale in any manner
that would violate any applicable federal or state securities law or other law
or regulation.  Stockholder is aware that the Parent Securities issued in the
Merger (including the Common Stock issuable upon exercise or conversion thereof)
will be "restricted securities" within the meaning of Rule 144 promulgated under
the Securities Act of 1933, as amended, and that no trading market for either
the Parent Warrants or the Parent Preferred Stock (both as defined in the Merger
Agreement) exists or is contemplated to exist.  Consequently, if Stockholder has
elected to receive the Securities and Cash Consideration, Stockholder has the
ability to hold the Parent Securities for an indefinite period of time. 
Pursuant to the Pennsylvania Securities Law any Pennsylvania purchaser hereby
agrees not to sell, transfer or otherwise dispose of the Parent Securities
within 12 months of the date of purchase.  

          C.  CONSENT.  Stockholder has carefully reviewed the Merger Agreement
and sought independent legal counsel as necessary to fully understand its terms
and conditions, and based upon such review and consultation approves of and
consents to the Merger Agreement and the Merger and the other transactions
contemplated by the Merger Agreement.  Stockholder has approved such agreement
and transactions in accordance with the Pennsylvania Consolidated Statutes and

                                     -3-

<PAGE>

other applicable laws and the Articles of Incorporation and Bylaws of Seller. 

     III.   ADDITIONAL AGREEMENTS.  

          A.  NO TRANSFER OF STOCK.  Unless and until the Merger Agreement 
shall have been terminated in accordance with its terms, Stockholder shall 
not sell, transfer or otherwise dispose of any right, title or interest in or 
to any of the Stockholder Shares.   

                                     -4-
<PAGE>

          B.  FEES AND EXPENSES.  If the Merger is completed and the legal fees
and legal expenses incurred by Seller in connection with the transactions
contemplated by the Merger Agreement exceed $25,000, then Stockholder agrees to
pay, in addition to the fees and expenses incurred by him in connection with the
Merger Agreement and this Agreement and the transactions contemplated thereby
and hereby, his Pro Rata Share (as hereinafter defined) of such fees and
expenses in excess of such amount.  If Parent or the Surviving Corporation pays
any such fees or expenses on behalf of Stockholder or Seller (which they shall
not be obligated to do), then Stockholder shall, promptly following notice
thereof from Parent or the Surviving Corporation, reimburse Parent or the
Surviving Corporation for such Stockholder's Pro Rata Share of such payment. 
"Pro Rata Share" means the number of shares of Seller Common Stock owned by
Stockholder as of the date hereof divided by the number of shares of Seller
Common Stock issued and outstanding as of the date hereof.  

          C.  COOPERATION; FURTHER ASSURANCES.  Stockholder agrees to use all
reasonable efforts (in all capacities, including, without limitation, as an
officer, director, employee and stockholder of Seller, as applicable) to take,
or cause to be taken, to do, or cause to be done, and to assist and cooperate
with Parent, Acquisition Sub and Seller in order to aid and facilitate the
completion of the Merger and the other transactions contemplated by the Merger
Agreement and this Agreement at the earliest practicable times.  In particular,
but without limitation, Stockholder agrees to use all reasonable efforts (in all
capacities, as provided above) to cause Seller to perform all of its agreements
in the Merger Agreement and to cause all of its representations and warranties
therein to be and remain true and correct.  In addition to the specific
provisions of the Merger Agreement, Stockholder further agrees to execute and
deliver such further documents and to perform such further actions as Parent or
the Surviving Corporation shall reasonably request from time to time, both
before and after the completion of the Merger, in connection with the
transactions contemplated by the Merger Agreement and this Agreement.


                                       -5-

          2.4  RELEASE.  Stockholder agrees and acknowledges that he has taken
all steps that he has deemed appropriate to fully inform himself of the
transactions contemplated by the Merger Agreement and to make an informed
decision to enter into this Agreement.  Stockholder further acknowledges that,
if he has elected to receive the Securities and Cash Consideration in the
Merger, (a) he has carefully reviewed the Private Placement Memorandum (as
defined in the Merger Agreement), and (b) he has not relied upon any
representation, warranty or other communication, written or oral, in electing to
receive Parent Securities, except for the information set forth in the Private
Placement Memorandum.  Further, Stockholder, on behalf of himself and his
affiliates, and for all of his and their respective affiliates, administrators,
trustees, beneficiaries and successors and assigns, does hereby fully, finally
and forever irrevocably and unconditionally release, acquit and discharge
Parent, Acquisition Sub and Seller, and all past, present and future parents,
subsidiaries and affiliates thereof, and all past, present and future officers,
directors, partners, employees, agents, attorneys, shareholders, accountants,
financial advisors, successors, heirs and assigns of such party or parties, of
and from any and all liabilities, claims or obligations, whensoever arising,
relating to or arising from the transactions contemplated by the Merger
Agreement (excluding from the foregoing only, if Stockholder has elected to
receive the Securities and Cash Consideration, any breach or default by or of
Parent under or with respect to the Parent Securities).  As further
consideration for this Agreement, each person granting or deemed to be granting
a release hereunder hereby agrees, represents and warrants that the matters
released herein are not limited to matters which are known or disclosed, and in
connection with the subject matter of this Agreement and the Merger Agreement,
each such person granting or deemed to be granting a release hereunder, hereby
waives any and all rights and benefits which it now has or in the future may
have conferred upon it by virtue of any provision of law of any jurisdiction
which may now exist or hereafter be enacted and which may be applicable to the
subject matter of this Agreement, purporting to grant to any such person fully
or partial relief from the releases contained in this Agreement, including,
without limitation, the provisions of Section 1542 of the Civil Code of the
State of California, or any similar or comparable provision of law of any
jurisdiction.  Said Section 1542 provides as follows:


                                       -6-

<PAGE>


     A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT
     KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE,
     WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE
     DEBTOR.

     IV.   INDEMNITY.

          A.  STOCKHOLDER INDEMNITIES.  Stockholder agrees to indemnify, hold
harmless and reimburse Parent, Acquisition Sub and Seller from and against any
and all losses, liabilities, damages, costs and expenses (including, without
limitation, reasonable attorneys' fees) (hereinafter "Losses"), actually
suffered or incurred by any of Parent, Acquisition Sub and/or Seller, or any
parent, subsidiary or affiliate thereof or any assignee or successor thereof,
and each officer and director of any of the foregoing, which is incurred as a
result of any breach of a representation, warranty or covenant of Stockholder in
this Agreement.

          B.  RECOVERIES.  The amount of any Loss suffered or incurred by any
person entitled to indemnification hereunder (an "Indemnified Person") shall be
reduced by the amount of any insurance proceeds or other cash receipts paid to
the Indemnified Person or any affiliate thereof as an offset against such Loss
(and no right of subrogation shall accrue to any insurer hereunder), including
any indemnification received by the Indemnified Person or such affiliate from an
unrelated party with respect to such Loss.

          C.  CLAIMS.  An Indemnified Person shall promptly give the
indemnifying party (an "Indemnifying Person") written notice of any matter which
such Indemnified Person has determined has given rise to a right of
indemnification under this Agreement, stating the amount of the Loss, if known,
and method of computation thereof, all with reasonable particularity (subject to
the last sentence of this paragraph).  The obligations and liabilities of any
party under this Section 3 with respect to Losses arising from claims,
assertions, events or proceedings of any third party (including, without
limitation, claims by any assignee or successor of the Indemnified Person or any
governmental agency), which are subject to the indemnification provided for in
this Section 3 ("Third Party Claims") shall be governed by and be subject to the
following additional terms and


                                       -7-

<PAGE>

conditions:  if any Indemnified Person shall receive written notice of any 
Third Party Claim, the Indemnified Person shall give the Indemnifying Person 
prompt written notice of such Third Party Claim (subject to the last sentence 
of this paragraph) and shall permit the Indemnifying Person, at its option, 
to participate in the defense of such Third Party Claim by counsel of its own 
choosing and at its expense.  Furthermore, if the Indemnifying Person 
acknowledges in writing its obligation to indemnify the Indemnified Person 
hereunder against any Loss (without limitation) that may result from such 
Third Party Claim, then the Indemnifying Person shall be entitled, at its 
option, to assume and control the defense against such Third Party Claim at 
its expense and through counsel of its choice if it gives prompt written 
notice of its intention to do so to the Indemnified Person unless, in the 
reasonable opinion of counsel for the Indemnified Person, there is a conflict 
or a potential conflict of interests between the Indemnified Person and the 
Indemnifying Person in such action, suit or proceeding, in which event the 
Indemnified Person shall be entitled to direct the defense with respect to, 
but only with respect to, those issues with respect to which such conflict 
exists. In the event the Indemnifying Person exercises its right to undertake 
the defense against any such Third Party Claim as provided above, the 
Indemnified Person shall, and it shall cause its affiliates to, cooperate 
with the Indemnifying Person in such defense and make available to he 
Indemnifying Person all pertinent records, materials and information in their 
possession or under their control relating thereto as is required by the 
Indemnifying Person.  No such Third Party Claim, except the settlement 
thereof which involves (i) the payment of money only for which any 
Indemnified Person is totally indemnified (without limitation) by the 
Indemnifying Person and (ii) the unconditional release from all related 
liability of the Indemnified Person, may be settled by the Indemnifying 
Person without the written consent of the Indemnified Person. Any settlement 
of a Third Party Claim by an Indemnified Person without the written consent 
of the Indemnifying Person shall discharge the Indemnifying Person from all 
liability hereunder with respect to the subject matter of such Third Party 
Claim.  The foregoing notwithstanding, the failure of any Indemnified Person 
to give any notice required to be given hereunder shall not affect such 
Indemnified Person's right to indemnification hereunder except to the extent 
the Indemnifying Person from whom such indemnity is sought shall have been 
actually and materially


                                      -8-

<PAGE>

prejudiced in its ability to defend the claim or action for which such 
indemnification is sought by reason of such failure.

the Merger, the Surviving Corporation) be required to engage counsel to seek to
enforce any of the provisions of this Agreement (whether or not a legal
proceeding is required to be filed), such party or parties shall be entitled, in
addition to its or their other remedies, to recover the fees and expenses of
counsel and, as

                               JOINDER AND CONSENT


     THIS JOINDER AND CONSENT (the "Agreement") is dated as of April 16, 
1996, by and among ALLIANCE IMAGING, INC., a Delaware corporation ("Parent"), 
ALLIANCE IMAGING OF PENNSYLVANIA, INC., a Pennsylvania corporation 
("Acquisition Sub"), and ________________ an individual ("Stockholder").

                               W I T N E S S E T H

     A.   Parent, Acquisition Sub and Royal Medical Health Services Inc., a 
Pennsylvania corporation ("Seller"), are parties to an Agreement and Plan of 
Merger dated as of April 16, 1996 (the "Merger Agreement"), pursuant to 
which, among other things, it is contemplated that Acquisition Sub will be 
merged with and into Seller (the "Merger") and that all of the shares of 
Seller's capital stock issued and outstanding will be converted into the 
right to receive either the Cash Only Consideration or the Securities and 
Cash Consideration (both as defined in and subject to the terms of the Merger 
Agreement).  A copy of the Merger Agreement is attached hereto as Exhibit A.

     B.   Stockholder is the record, legal and beneficial owner of 41,736 
shares (approximately 41.7% of the issued and outstanding capital stock of 
Seller as of the date hereof) (the "Stockholder Shares") of the Common Stock, 
no par value, of Seller ("Seller Common Stock").  Stockholder has approved of 
and consented to the Merger Agreement and the Merger and the other 
transactions contemplated by the Merger Agreement.  As a substantial 
stockholder of Seller, Stockholder will derive substantial benefits from the 
closing of such transactions.

     C.   The execution and delivery of this Agreement by Stockholder is a 
condition to the obligations of Parent and Acquisition Sub under the Merger 
Agreement.  In order to induce Parent and Acquisition Sub to complete the 
Merger and the other transactions contemplated by the Merger Agreement and to 
satisfy such condition, Stockholder has agreed to the provisions herein.

<PAGE>

     NOW, THEREFORE, in consideration of the mutual covenants, agreements, 
representations and warranties contained herein and, in the case of Parent 
and Acquisition Sub, in the Merger Agreement, Parent, Acquisition Sub and 
Stockholder agree as follows:

     II.   REPRESENTATIONS AND WARRANTIES.  Stockholder hereby represents and 
warrants to Parent and Acquisition Sub as follows:  









                                   -2-

<PAGE>

          A.  OWNERSHIP OF SHARES.  Stockholder is the record, legal and 
beneficial owner of all of the Stockholder Shares referred to in Recital B 
above, and no other person or entity has any right, title or interest in or 
to any of such shares.  Stockholder does not have any option, warrant or 
other right to acquire any shares of capital stock of Seller.  At the Closing 
(as defined in the Merger Agreement), in accordance with Section 2.5(i) of 
the Merger Agreement, Stockholder will deliver to the Surviving Corporation 
(as defined in the Merger Agreement) for cancellation all certificates 
representing the Stockholder Shares, free and clear of all liens, claims and 
encumbrances of any party and of any nature whatsoever.  

          B.  RESALE.  As of the date hereof and the Closing, Stockholder 
does not have and will not have a present plan or intention of disposing of 
any Parent Securities (as defined in the Merger Agreement) acquired pursuant 
to the Merger, if any.  Assuming completion of the Merger, Stockholder will 
acquire such Parent Securities for investment purposes and not for resale in 
any manner that would violate any applicable federal or state securities law 
or other law or regulation.  Stockholder is aware that the Parent Securities 
issued in the Merger (including the Common Stock issuable upon exercise or 
conversion thereof) will be "restricted securities" within the meaning of 
Rule 144 promulgated under the Securities Act of 1933, as amended, and that 
no trading market for either the Parent Warrants or the Parent Preferred 
Stock (both as defined in the Merger Agreement) exists or is contemplated to 
exist.  Consequently, if Stockholder has elected to receive the Securities 
and Cash Consideration, Stockholder has the ability to hold the Parent 
Securities for an indefinite period of time. Pursuant to the Pennsylvania 
Securities Law any Pennsylvania purchaser hereby agrees not to sell, transfer 
or otherwise dispose of the Parent Securities within 12 months of the date of 
purchase.  

          C.  CONSENT.  Stockholder has carefully reviewed the Merger 
Agreement and sought independent legal counsel as necessary to fully 
understand its terms and conditions, and based upon such review and 
consultation approves of and consents to the Merger Agreement and the Merger 
and the other transactions contemplated by the Merger Agreement.  Stockholder

other applicable laws and the Articles of Incorporation and Bylaws of Seller. 

          D.  SELLER REPRESENTATIONS AND WARRANTIES.  All of the 
representations and warranties of Seller in the Merger Agreement (including, 
without limitation, those in Article 4 of such agreement) were, are and will 
be, as of the respective dates made or deemed to have been made pursuant to 
the terms of the Merger Agreement, true and correct in all respects 
(qualified by materiality to the extent provided therein).  Stockholder 
agrees that the representation and warranty contained in this Section 1.4 
shall survive consummation of 

                                   -4-

<PAGE>

the Merger and shall remain in full force and effect for the period of 
limitations provided under applicable law.

     III.   ADDITIONAL AGREEMENTS.

          A.  NO TRANSFER OF STOCK.  Unless and until the Merger Agreement 
shall have been terminated in accordance with its terms, Stockholder shall 
not sell, transfer or otherwise dispose of any right, title or interest in or 
to any of the Stockholder Shares.  

          B.  FEES AND EXPENSES.  If the Merger is completed and the legal 
fees and legal expenses incurred by Seller in connection with the 
transactions contemplated by the Merger Agreement exceed $25,000, then 
Stockholder agrees to pay, in addition to the fees and expenses incurred by 
him in connection with the Merger Agreement and this Agreement and the 
transactions contemplated thereby and hereby, his Pro Rata Share (as 
hereinafter defined) of such fees and expenses in excess of such amount.  If 
Parent or the Surviving Corporation pays any such fees or expenses on behalf 
of Stockholder or Seller (which they shall not be obligated to do), then 
Stockholder shall, promptly following notice thereof from Parent or the 
Surviving Corporation, reimburse Parent or the Surviving Corporation for such 
Stockholder's Pro Rata Share of such payment. "Pro Rata Share" means the 
number of shares of Seller Common Stock owned by Stockholder as of the date 
hereof divided by the number of shares of Seller Common Stock issued and 
outstanding as of the date hereof.  

          C.  COOPERATION; FURTHER ASSURANCES; NAME CHANGES.  Stockholder 
agrees to use all reasonable efforts (in all capacities, including, without 
limitation, as an officer, director, employee and stockholder of Seller, as 
applicable) to take, or cause to be taken, to do, or cause to be done, and to 
assist and cooperate with Parent, Acquisition Sub and Seller in order to aid 
and facilitate the completion of the Merger and the other transactions 
contemplated by the Merger Agreement and this Agreement at the earliest 
practicable times. In particular, but without limitation, Stockholder agrees 
to use all reasonable efforts (in all capacities, as provided above) to cause 
Seller to perform all of its agreements in the Merger Agreement and to cause 
all of its representations and warranties therein to be and remain true and 
correct.  In addition to the specific provisions of the Merger Agreement, 
Stockholder further agrees to execute and 

                                   -5-

<PAGE>

deliver such further documents and to perform such further actions as Parent 
or the Surviving Corporation shall reasonably request from time to time, both 
before and after the completion of the Merger, in connection with the 
transactions contemplated by the Merger Agreement and this Agreement.  In 
addition, Stockholder agrees to cause all affiliated and related entities of 
Seller and all entities owned or controlled by Stockholder that are engaged 
in the diagnostic medical imaging business, to take all necessary steps to 
change their names as promptly following the Closing as is practicable (and 
in any event within 30 days thereof) to eliminate the word "Royal" and any 
derivative or similar word or phrase.

          2.4 RELEASE.  Stockholder agrees and acknowledges that he has taken 
all steps that he has deemed appropriate to fully inform himself of the 
transactions contemplated by the Merger Agreement and to make an informed 
decision to enter into this Agreement.  Stockholder further acknowledges 
that, if he has elected to receive the Securities and Cash Consideration in 
the Merger, (a) he has carefully reviewed the Private Placement Memorandum 
(as defined in the Merger Agreement), and (b) he has not relied upon any 
representation, warranty or other communication, written or oral, in electing 
to receive Parent Securities, except for the information set forth in the 
Private Placement Memorandum.  Further, Stockholder, on behalf of himself and 
his affiliates, and for all of his and their respective affiliates, 
administrators, trustees, beneficiaries and successors and assigns, does 
hereby fully, finally and forever irrevocably and unconditionally release, 
acquit and discharge Parent, Acquisition Sub and Seller, and all past, 
present and future parents, subsidiaries and affiliates thereof, and all 
past, present and future officers, directors, partners, employees, agents, 
attorneys, shareholders, accountants, financial advisors, successors, heirs 
and assigns of such party or parties, of and from any and all liabilities, 
claims or obligations, whensoever arising, relating to or arising from the 
transactions contemplated by the Merger Agreement (excluding from the 
foregoing only (i) any breach of an obligation under the employment agreement 
with Stockholder referred to therein and (ii) if Stockholder has elected to 
receive the Securities and Cash Consideration, any breach or default by or of 
Parent under or with respect to the Parent Securities).  As further 
consideration for this Agreement, each person granting or deemed to be 
granting a release 

                                   -6-

<PAGE>

hereunder hereby agrees, represents and warrants that the matters released 
herein are not limited to matters which are known or disclosed, and in 
connection with the subject matter of this Agreement and the Merger 
Agreement, each such person granting or deemed to be granting a release 
hereunder, hereby waives any and all rights and benefits which it now has or 
in the future may have conferred upon it by virtue of any provision of law of 
any jurisdiction which may now exist or hereafter be enacted and which may be 
applicable to the subject matter of this Agreement, purporting to grant to 
any such person fully or partial relief from the releases contained in this 
Agreement, including, without limitation, the provisions of Section 1542 of 
the Civil Code of the State of California, or any similar or comparable 
provision of law of any jurisdiction.  Said Section 1542 provides as follows:

     A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT  
     KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE       
     RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS 
     SETTLEMENT WITH THE DEBTOR.

     IV.   INDEMNITY.

          A.  STOCKHOLDER INDEMNITIES.  Stockholder agrees to indemnify, hold 
harmless and reimburse Parent, Acquisition Sub and Seller from and against 
any and all losses, liabilities, damages, costs and expenses (including, 
without limitation, reasonable attorneys' fees) (hereinafter "Losses"), 
actually suffered or incurred by any of Parent, Acquisition Sub and/or 
Seller, or any parent, subsidiary or affiliate thereof or any assignee or 
successor thereof, and each officer and director of any of the foregoing, 
which is incurred as a result of any breach of a representation, warranty or 
covenant of Stockholder in this Agreement.

          B.  RECOVERIES.  The amount of any Loss suffered or incurred by any 
person entitled to indemnification hereunder (an "Indemnified Person") shall 
be reduced by the amount of any insurance proceeds or other cash receipts 
paid to the Indemnified Person or any affiliate thereof as an offset against 
such Loss (and no right of subrogation shall accrue to any insurer 
hereunder), including any indemnification received by the Indemnified Person 
or such affiliate from an unrelated party with respect to such Loss.

                                   -7-


<PAGE>

          C.  CLAIMS.  An Indemnified Person shall promptly give the 
indemnifying party (an "Indemnifying Person") written notice of any matter 
which such Indemnified Person has determined has given rise to a right of 
indemnification under this Agreement, stating the amount of the Loss, if 
known, and method of computation thereof, all with reasonable particularity 
(subject to the last sentence of this paragraph).  The obligations and 
liabilities of any party under this Section 3 with respect to Losses arising 
from claims, assertions, events or proceedings of any third party (including, 
without limitation, claims by any assignee or successor of the Indemnified 
Person or any governmental agency), which are subject to the indemnification 
provided for in this Section 3 ("Third Party Claims") shall be governed by 
and be subject to the following additional terms and conditions:  if any 
Indemnified Person shall receive written notice of any Third Party Claim, the 
Indemnified Person shall give the Indemnifying Person prompt written notice 
of such Third Party Claim (subject to the last sentence of this paragraph) 
and shall permit the Indemnifying Person, at its option, to participate in 
the defense of such Third Party Claim by counsel of its own choosing and at 
its expense.  Furthermore, if the Indemnifying Person acknowledges in writing 
its obligation to indemnify the Indemnified Person hereunder against any Loss 
(without limitation) that may result from such Third Party Claim, then the 
Indemnifying Person shall be entitled, at its option, to assume and control 
the defense against such Third Party Claim at its expense and through counsel 
of its choice if it gives prompt written notice of its intention to do so to 
the Indemnified Person unless, in the reasonable opinion of counsel for the 
Indemnified Person, there is a conflict or a potential conflict of interests 
between the Indemnified Person and the Indemnifying Person in such action, 
suit or proceeding, in which event the Indemnified Person shall be entitled 
to direct the defense with respect to, but only with respect to, those issues 
with respect to which such conflict exists. In the event the Indemnifying 
Person exercises its right to undertake the defense against any such Third 
Party Claim as provided above, the Indemnified Person shall, and it shall 
cause its affiliates to, cooperate with the Indemnifying Person in such 
defense and make available to he Indemnifying Person all pertinent records, 
materials and information in their possession or under their control relating 
thereto as is required by the Indemnifying Person.  No such Third Party 
Claim, except the settlement thereof which involves (i) the 

                                   -8-

<PAGE>

payment of money only for which any Indemnified Person is totally indemnified 
(without limitation) by the Indemnifying Person and (ii) the unconditional 
release from all related liability of the Indemnified Person, may be settled 
by the Indemnifying Person without the written consent of the Indemnified 
Person. Any settlement of a Third Party Claim by an Indemnified Person 
without the written consent of the Indemnifying Person shall discharge the 
Indemnifying Person from all liability hereunder with respect to the subject 
matter of such Third Party Claim.  The foregoing notwithstanding, the failure 
of any Indemnified Person to give any notice required to be given hereunder 
shall not affect such Indemnified Person's right to indemnification hereunder 
except to the extent the Indemnifying Person from whom such indemnity is 
sought shall have been actually and materially prejudiced in its ability to 
defend the claim or action for which such indemnification is sought by reason 
of such failure.

     V.   GENERAL AGREEMENTS.

       3.   PURCHASE PRICE.
   
            .1  CONSIDERATION FOR PURCHASED ASSETS; ALLOCATION. 
   Subject to the terms and conditions of this Agreement, at the
   Closing, Buyer shall pay to Seller as consideration for the
   Purchased Assets the purchase price (the "Purchase Price")
   equal to (a) Six Hundred Twenty-Eight Thousand Dollars
   ($628,000) minus (b) the sum of (x) the excess (if any) of the
   amount of cash held by Seller at the Closing (including any
   cash transferred from Royal in respect of trade payables owed
   by Royal to Seller) over the amount of accrued and outstanding
   salary and payroll and employment taxes payable as of the
   Closing and (y) the excess (if any) of the amount of salary
   and distributions actually paid by Seller to Mr. Graham and
   Mr. Calfo prior to the Closing over the amount of pro-rated
   salary and distributions Seller is permitted to pay to Mr.
   Graham and Mr. Calfo with respect to periods prior to the
   Closing under part (y) of Section 5.10 hereof.  The Purchase
   Price shall be paid by Buyer in cash or by wire transfer of
   funds to an account designated by Seller.  The Purchase Price
   shall be allocated as follows:
   
             Tractors                     $150,000
   
             Accounts Receivable          Face Amount as of
             and Prepaid Amounts          Closing

             Intangibles                  Purchase Price.
   
   The parties agree to use such allocated amounts in reporting
   the transaction contemplated hereunder for all state, federal
   and local tax purposes, and not to take any inconsistent
   position in any tax filing.  Buyer will be responsible for
   paying any sales taxes required to be paid in connection with
   the purchase of the Purchased Assets, but Seller shall
   reasonably cooperate with Buyer to minimize the extent to
   which such taxes are legally required to be paid.
   
       4.   CLOSING.
   
            .1  TIME AND PLACE.  The closing hereunder (the

   counsel may reasonably deem to be necessary or desirable in
   order to effect or evidence the transfer of the Purchased
   Assets to Buyer.
   
       5.   REPRESENTATIONS AND WARRANTIES OF SELLER.  As an
   inducement for Buyer to enter into and consummate the
   transactions contemplated by this Agreement, the Company and

            .1  EXISTENCE AND RIGHTS; COMPLIANCE WITH LAWS. 
   
                 .1  EXISTENCE AND RIGHTS.  Seller (i) is a
   corporation duly organized and validly existing in good
   standing under the laws of the Commonwealth of Pennsylvania
   without limit as to the duration of its existence; (ii) has
   the corporate power and adequate authority, rights and
   franchises to own its properties and to carry on its business
   as now conducted and to make and carry out this Agreement; and
   (iii) is duly qualified and in good standing in each
   jurisdiction in which its owned or leased properties or the
   character of its business makes such qualification necessary,
   or, if not so qualified, the failure to so qualify will not
   have a materially adverse effect upon its financial condition,
   properties, or business or results of operation.  The copies
   of the Articles of Incorporation and Bylaws of Seller
   previously delivered to Buyer remain complete and in full
   force and effect.
   
                 .2  COMPLIANCE WITH LAWS.  Seller's business
   has been and is being conducted in all material respects in
   accordance with all applicable federal, state and local laws
   and regulations and rules and regulations of all applicable
   private third party insurers and reimbursers of health care
   costs and expenses, including, without limitation, such laws,
   regulations and rules as relate to the practice of medicine
   and the provision of medical diagnostic mobile imaging
   services and otherwise. 
   
       .2  STOCK.  Seller's authorized capital stock consists
   of 10,000 shares of a single class of stock, all of which have
   been duly authorized and are validly issued and outstanding as
   of the date hereof.  All shares of such outstanding capital
   stock are fully paid and non-assessable, are owned
   beneficially and of record by the Shareholders, and were
   issued in compliance with all applicable state and federal
   securities laws and other applicable laws.  There are no
   outstanding securities convertible into, or options, warrants,
   rights, calls or other commitments of any nature relating to,
   the issuance of any securities of Seller.
   
       .3  AGREEMENT AUTHORIZED.  The execution, delivery and
   performance of this Agreement by Seller have been duly and
   validly authorized by all necessary corporate action

                                       -6-

<PAGE>


   (including, without limitation, approval by the Board of
   Directors and stockholders of Seller in accordance with
   applicable law) on the part of Seller and do not require
   notice to, or the consent or approval of, any governmental
   body or other regulatory authority.  This Agreement is a
   legal, valid and binding obligation of Seller, enforceable
   against Seller in accordance with its terms.  
   
       .4  SUBSIDIARIES.  Seller has no subsidiaries and no
   equity interests in any other entities nor any obligation,
   option or right to acquire any such interest.  
   
       .5  CONTRACTS.  Schedule 5.5 attached hereto lists each
   of the rental and lease agreements, customer contracts and
   other agreements (including, without limitation, those
   relating to indebtedness or lease obligations secured by or
   relating to Equipment) (the "Assumed Contracts").  There is no
   material default in any obligation to be performed by Seller
   under any Assumed Contract and Seller has not waived any
   material right under any Assumed Contract, and, to Seller's
   knowledge, no counterparty to any Assumed Contract is in
   material default of any obligation thereunder.  Seller does
   not have any outstanding contract, commitment or undertaking
   which will result in any material loss upon completion or
   performance thereof after allowance for general and
   administrative selling and distribution expenses or will be
   unreasonably adverse, onerous or harmful to its assets,
   business, operation or financial condition.  Seller is not in
   default nor is there any basis for any claim of default under
   any Assumed Contract, and Seller has not waived any material
   right under any such Assumed Contract, except for defaults and
   waivers which are not material to the financial condition,
   properties, business or results of operations of Seller. 
   Seller (including its employees) is not restricted by
   agreement from carrying on its business anywhere in the United
   States.
   
       .6  NO CONFLICT.  The execution, delivery and perform-
   ance of this Agreement will not (i)  breach or constitute
   grounds for the occurrence or declaration of an acceleration
   of payment or a default or a right of termination under any
   agreement, indenture, undertaking or other instrument to which
   Seller is a party or by which it or any of its properties may
   be bound or affected; (ii) violate any provision of law or any

                                      -7-

<PAGE>

   regulation or any order, judgment or decree of any court or
   other agency of government, the violation of which could have
   a material adverse effect on the financial condition,
   properties, business or results of operations of Seller;
   (iii) violate any provision of the Articles of Incorporation
   or Bylaws of Seller; or (iv) result in the creation or
   imposition of (or the obligation to create or impose) any
   lien, charge or encumbrance on, or security interest in or on,
   any of its properties.  Without limiting the generality of the
   foregoing, the execution, delivery and performance of this
   Agreement does not and will not require the consent of any
   third party under any Assumed Contract except as set forth on
   Schedule 5.6 hereto.
   
       .7  LITIGATION.  Except as set forth on Schedule 5.7,
   there is no litigation, investigation, arbitration or other
   proceedings (formal or informal) pending or, to the best
   knowledge of Seller, threatened against or affecting it or its
   properties; nor does Seller know of any reasonable basis for
   any litigation, investigation, arbitration or other pro-
   ceedings (formal or informal), the results of which could have
   a material adverse effect on its financial condition,
   properties, business or results of operations.  Seller is not
   in default with respect to any order, writ, injunction, decree
   or demand of any court or other governmental or regulatory
   authority.  
   
       .8  FINANCIAL CONDITION.  The balance sheets of Seller
   as of December 31, 1995, February 29, 1996, and March 31, 1996
   and the related profit and loss and cash flow statements for
   the periods ended on those dates, and the related notes for
   such financial statements, copies of which have heretofore
   been or will be delivered to Buyer by Seller, and all other
   historical financial statements and data submitted in writing
   by Seller to Buyer at any time (collectively, the "Financial
   Statements"), are or, when delivered, will be true and correct
   as of the respective dates thereof, and the Financial
   Statements truly present and will truly present the financial
   condition of Seller as at the respective dates thereof and the
   results of the operations of Seller for the respective periods
   covered thereby, and have been and will have been prepared in
   accordance with generally accepted accounting principles on a
   basis consistently maintained ("GAAP").  Seller has no
   knowledge of any liabilities or guarantees, matured or

                                       -8-

<PAGE>

   unmatured, contingent or otherwise, as of the respective dates
   of the Financial Statements not accurately reflected in the
   Financial Statements, and none have arisen since those times
   except in the ordinary and usual course of business.  With
   respect to Seller's contracts, commitments and loss
   contingencies, the Financial Statements contain and reflect
   adequate reserves.
   
       .9  BOOKS AND RECORDS.  Seller maintains a system of
   internal accounting control sufficient to provide reasonable
   assurances that (i) transactions are executed in accordance
   with management's general or specific authorization,
   (ii) transactions are recorded as necessary to permit prepara-
   tion of financial statements in conformity with GAAP,
   (iii) access to assets is permitted only in accordance with
   management's general or specific authorization, and (iv) the
   recorded accounting for assets is compared with the existing
   assets at reasonable intervals and appropriate action is taken
   with respect to any differences.  
   
       .10 NO SUBSEQUENT CHANGES.  Except as contemplated in
   this Agreement or reflected in any Schedule attached hereto,
   since December 31, 1995, (i) there have been no material
   adverse changes (whether by sale, destruction, pledge, lease
   or otherwise and whether or not covered by insurance) in the
   assets (including licenses, permits and franchises),
   liabilities or financial condition of Seller, and (ii) Seller
   has not entered into any commitments, contracts or
   transactions not reflected in the Financial Statements, as
   required in accordance with GAAP, except in each case for
   changes in the ordinary and usual course of business.  Since
   the respective dates of the Financial Statements, (a) Seller
   has not, directly or indirectly, paid, declared, or set aside
   any dividends or distributions with respect to, nor
   repurchased, any of its capital stock or securities of any
   class, and (b) to the knowledge of Seller, no events have
   occurred which have had or can reasonably be expected to have
   a material adverse effect on the financial condition,
   properties, business, results of operations or prospects of
   Seller.  Since December 31, 1995, each of Mark J. Graham and
   Albert F. Calfo, II has earned salary (including all cash
   compensation) at the rate of $1,000 per month and neither of
   them has received any dividend or other distribution on Seller
   Common Stock or any other payment or distribution of any kind,


                                      -9-

<PAGE>


   except for (x) prior distributions totalling $14,500 to each
   of Mr. Graham and Mr. Calfo and (y) additional distributions
   of $1,687.50 per month (prorated for partial months on a daily
   basis through the Closing) to each of Mr. Graham and Mr.
   Calfo.
   
       .11 TITLE TO AND CONDITION OF ASSETS.  Seller has no
   interest in real property, including, without limitation, any
   leasehold interest.  Seller has good, clear and marketable
   title to its assets (including, without limitation, those
   shown in the Financial Statements, except as subsequently sold
   in the ordinary course of business) and the same are not
   subject to any mortgages, deeds of trust, pledges, security
   interests, leases, licenses or other encumbrances other than
   indicated in the Financial Statements or listed on Schedule
   5.5 or 5.11 hereto.  None of the assets of Seller, tangible or
   intangible, are located outside of the United States and
   Seller does not own or hold any stock or securities, or
   receivables from or claims against foreign entities.  All of
   the assets and currently used properties of Seller are in good
   operating condition, ordinary wear and tear excepted.  
   
       .12 ENVIRONMENTAL MATTERS.  Except as set forth on
   Schedule 5.12, Seller has all permits, licenses and other
   authorizations required for the operation of its business (as
   presently conducted) under federal, state, and local laws
   relating to pollution, protection of the environment and the
   storage, presence and discharge of chemicals and other
   substances (collectively, "Environmental Laws").  There is no
   civil, criminal or administrative action, suit, demand, claim,
   hearing, notice of violation, investigation, proceeding,
   notice or demand letter under the Environmental Laws pending,
   or to the best knowledge of Seller threatened, against Seller
   or any of its owned or leased real or personal property. 
   Neither Seller nor, to the best knowledge of Seller, any other
   person or entity has placed, stored, buried, dumped or
   disposed of any regulated or prohibited substances or any
   materials produced by, or resulting from, any business,
   commercial or industrial activities, operations or processes
   on, beneath, or adjacent to any owned or leased real property
   of Seller, except to the extent handled or reported and
   remedied in all material respects in accordance with
   applicable Environmental Laws.  To the best knowledge of
   Seller, no employee of Seller has been exposed in the course

                                     -10-

<PAGE>


   of his or her employment with Seller to any regulated or
   prohibited substances or any materials produced or used by
   Seller in any manner that could give rise to any material
   liability under any applicable Environmental Law against
   Seller or its properties.  Seller has not received any notice
   from any governmental agency or private or public entity
   advising Seller that it is responsible or potentially
   responsible for actual or potential response costs with
   respect to a release, a threatened release or clean-up of
   materials (including hazardous substances as defined in any
   Environmental Laws) nor is Seller aware of any facts that
   might reasonably be expected to give rise to any such notice.  

       .13 TAX STATUS.  
   
            .1  RETURNS FILED.  Seller has timely filed all
   Tax Returns required to have been filed by it and has paid or
   accrued all Taxes due to any taxing authority with respect to
   all taxing periods ending on or prior to the date hereof; and
   all such Tax Returns are true, correct and complete in all
   material respects.  The Financial Statements include an
   adequate reserve for all Taxes not yet due or with respect to
   which Tax Returns, as of the Closing, are not required to have
   been filed, in each case to reflect the operations of Seller
   through the Closing.  There is no pending Tax audit by a
   governmental authority against or affecting Seller.
   
            .2  COLLECTIONS AND PAYMENTS.  (a) All amounts
   that are required to be collected or withheld by Seller have
   been duly collected or withheld, and (b) all such amounts that
   are required to be remitted to any taxing authority (including
   license and other similar fees payable to the Department of
   Motor Vehicles and other governmental agencies) have been duly
   remitted.
   
            For purposes of this Agreement, "Taxes" means all
   taxes imposed of any nature including federal, state, local or
   foreign net income tax, alternative or add-on minimum tax,
   profits or excess profits tax, franchise tax, gross income,
   adjusted gross income or gross receipts tax, employment
   related tax (including employee withholding and employer
   payroll tax, FICA and FUTA), real and personal property tax or
   ad valorem tax, sales or use tax, excise tax, stamp tax or
   duty, any withholding or back up withholding tax, value added

   governmental authority (domestic or foreign) responsible for
   the imposition of such tax.  "Tax Return" means all returns,
   reports, forms or other information required to be filed with
   respect to any Taxes.
   
       .14 MARKS.  Seller owns or has the right to use its
   corporate name in all jurisdictions in which the business of
   Seller is conducted as of the date hereof.  Seller is not
   infringing on any trademark, trade name, service mark, copy-
   right, patent, or license in the operation of its business,
   and Seller does not know of any third party who has asserted
   any claim concerning such an infringement.  
   
       .15  ERISA.  Neither Seller nor any affiliated company
   under common control of or with Seller within the meaning of
   the Employee Retirement Income Security Act of 1974, as
   amended ("ERISA"), maintains on the date hereof any employee
   benefit plan subject to the provisions of ERISA, nor
   contributes to any such plan (including any multi-employer
   plan) on behalf of its employees.  Seller does not have any
   unfunded pension, profit sharing or deferred compensation
   plans or arrangements.  Seller has complied in all respects
   with, and is currently in compliance with, the continuation of
   benefits provisions applicable to former employees under ERISA
   and similar federal and state laws and regulations.
   
       .16 INSURANCE.  Schedule 5.16 to this Agreement sets
   forth all insurance policies of Seller that are currently in
   effect, including in each case the type and amount of coverage
   and carrier.  All of the material properties and assets of
   Seller which are of an insurable character are insured against
   loss or damage by fire, casualty and other risks, and Seller
   has general liability insurance with independent carriers, in
   each case to the extent and in the manner customary for
   companies engaged in a similar business or owning similar
   assets.  
       
       .17 LABOR MATTERS.  Except for Mark J. Graham and Albert
   F. Calfo, II, Seller has no employees.
   
                                     -12-

<PAGE>

       .18 MANAGEMENT TRANSACTIONS.  Other than the
   Shareholders' interest in Royal, none of Seller's officers,
   directors or stockholders (i) owns, directly or indirectly,
   individually or collectively, any interest in a corporation,
   partnership, firm or association which is a competitor,
   potential competitor, customer or supplier of Seller or has an
   existing contractual, business or financial relationship with
   Seller, or (ii) owes any money to or is owed any money by
   Seller, other than indebtedness for compensation earned and
   not yet paid in the ordinary course of business.    
   
       .19 NO FINDER'S FEES.  Neither Seller nor any of its
   officers, directors, agents or employees have employed or
   incurred any liability to any broker, finder or agent for any
   brokerage fees, finder's fees, commissions or other amounts
   with respect to the transactions contemplated by this
   Agreement, and Seller agrees to hold Buyer harmless from and
   against damages or cost incurred by reason of any such
   assertions.
   
       .20 NO UNDISCLOSED LIABILITIES.  Except as set forth in
   Schedule 5.20, to the best of Seller's knowledge, there is no
   outstanding claim, liability or obligation of any nature,
   whether absolute, accrued, known or unknown, contingent or
   otherwise, affecting Seller or its business, other than
   obligations incurred in the ordinary course of the business
   consistent with Seller's prior practices, none of which is
   materially adverse individually to the financial condition,
   results of operations or prospects of Seller and all of which
   are not materially adverse in the aggregate to the financial
   condition, results of operations or prospects of Seller.
   
       .21 DISCLOSURE.  This Agreement (including its Schedules
   and Exhibits) and each other document and certificate prepared
   or delivered by or on behalf of Seller and furnished or to be
   furnished to Buyer in connection herewith, as of their
   respective dates, did not, and as of the date hereof, do not
   (i) contain any untrue statement of a material fact, or
   (ii) omit to state a material fact necessary in order to make
   the statements contained herein and therein not misleading. 
   Except as disclosed in this Agreement (including its Schedules
   and Exhibits) and such other documents and certificates, there
   is no fact known to Seller (other than matters relating to
   economic conditions generally) which is materially adverse to

                                       -13-

<PAGE>

   the financial condition, results of operations or prospects of
   Seller.
   
       6.   REPRESENTATIONS AND WARRANTIES OF BUYER.  As an
   inducement for Seller and Shareholders to enter into and
   consummate the transactions contemplated by this Agreement,

   consolidated financial condition of Buyer.
   
            .2  COMPLIANCE WITH LAWS.  Buyer's business has

   affecting it or its properties; nor does Buyer know of any
   reasonable basis for any litigation, investigation,

   (collectively, "Representatives") access during normal
   business hours to all of the assets, properties, books and
   records of Seller and such additional information concerning
   the business and properties of Seller as Buyer or its

   contemplated hereby, until such time as (a) such information

   counsel that any such information is required by law or
   governmental process to be disclosed or (c) such information
   becomes known to any of them through a third party that is not

   with the bulk transfer provisions of the Uniform Commercial
   Code, if applicable, and Seller shall indemnify and hold Buyer
   harmless from any claims of Seller's creditors that result
   from such waiver (except to the extent that any such claim
   constitutes an Assumed Liability hereunder).  
   
       9.   CONDITIONS TO OBLIGATIONS OF BUYER.  The obligations

   (having been deemed to have been made again at and as of the
   Closing) shall be true and correct in all material respects as
   of the Closing; PROVIDED, HOWEVER, that if any such
   representation or warranty is already qualified by
   materiality, for purposes of determining whether this
   condition has been satisfied, such representation or warranty
   as so qualified must be true and correct in all respects. 
   Each obligation of Seller and the Shareholders under this
   Agreement required to be performed by it at or prior to the
   Closing shall have been duly performed and complied with in
   all material respects as of the Closing.  At the Closing,

   sentence of this clause (ii), with respect to any consent or
   waiver listed on Schedule 5.6 as being required from a
   provider of equipment financing under a "due on sale", change
   of control or similar provision, if such provider of equipment
   financing is not a Related Party Lender, the obtaining of the

            .7 SATISFACTION OF RMG RECEIVABLE. Royal Medical
   Group, Inc. ("RMG") shall have paid in full to Royal all
   amounts owed by RMG to Royal; provided, however, $104,107 of
   such amounts owed may be satisfied by the assignment to Royal
   by RMG of the $104,107 amount which Seller owes to RMG as of
   the date hereof (the "Trucking Payable") and the execution by
   RMG of a release of Buyer and Seller with respect to the
   Trucking Payable in form and substance satisfactory to Buyer;
   and

            .8 DUE DILIGENCE. Buyer shall have completed its

   respects as of the date hereof and (having been deemed to have
   been made again at and as of the Closing) shall be true and
   correct in all material respects as of the Closing; PROVIDED,
   HOWEVER, that if any such representation or warranty is
   already qualified by materiality, for purposes of determining
   whether this condition has been satisfied, such representation
   or warranty as so qualified must be true and correct in all
   respects. Each obligation of Buyer under this Agreement
   required to be performed by Buyer at or prior to the Closing
   shall have been duly performed and complied with in all
   material respects as of the Closing. At the Closing, Seller
   shall have received a certificate, dated the Closing Date and
   duly executed by the chief executive officer and the chief
   financial officer of Buyer, to the effect that the conditions
   set forth in this Section 10.1 have been satisfied;

   officers and others as Seller may have reasonably requested to
   evidence compliance with the conditions set forth in this
   Section 10.
   
       11.  COVENANTS AND AGREEMENTS OF THE PARTIES.  The
   parties mutually covenant and agree as follows:
   
            .1 CONDUCT AND PRESERVATION OF BUSINESS.  Until
   the Closing, Seller shall conduct the Business only in the
   ordinary and usual course of business consistent with past
   practices and, with respect to the Business, shall use its
   best efforts to (i) preserve its business organization intact,
   (ii) keep available the services of its employees,

   or investigation which is threatened or commenced against
   Seller, or against any officer, employee, agent, consultant or

   Purchased Assets, the Business, or this Agreement or the
   transactions contemplated hereby.  
   
            .3 EXPENSES OF SALE.  Seller and the Shareholders,
   on the one hand, and Buyer, on the other hand, shall each bear

                                       -21-

<PAGE>


   their own direct and indirect expenses incurred in connection
   with the negotiation and preparation of this Agreement and the
   consummation and performance of the transactions contemplated
   hereby.
   
            .4 ACTIONS WITH RESPECT TO CLOSING.  The parties
   agree to use their reasonable best efforts (not involving
   unreasonable expense) to bring about the satisfaction of the
   conditions precedent to the Closing and to cause the covenants
   and agreements contained in this Section 11 to be satisfied
   and performed hereunder by each of them.
   
       12.  INDEMNITY. 
   
            .1 SELLER'S INDEMNITY.  Buyer shall be
   indemnified, held harmless and reimbursed by each of Seller
   and the Shareholders, jointly and severally, for any and all
   losses, liabilities, damages, costs and expenses (including,
   without limitation, reasonable attorneys' fees) (hereinafter
   "Losses"), actually suffered or incurred by Buyer, or any
   parent, subsidiary or affiliate thereof or any assignee or
   successor thereof, and each officer and director of any of the
   foregoing, which is incurred as a result of (i) any breach of
   any representation, warranty or agreement made by Seller in
   this Agreement (including all Schedules and Exhibits hereto
   and all instruments and undertakings delivered or made in
   connection herewith), (ii) any Unassumed Liability, or (iii)
   except for Assumed Liabilities, the operation of the Business
   prior to the Closing.
   
            .2 BUYER'S INDEMNITY.  Seller and each of the
   Shareholders shall be indemnified, held harmless and
   reimbursed by Buyer for any and all Losses actually suffered
   or incurred by Seller or any assignee or successor thereof,
   which is incurred as a result of (i) any breach of any
   representation, warranty or agreement made by Buyer in this
   Agreement (including all Schedules and Exhibits hereto and all
   instruments and undertakings delivered or made in connection
   herewith), or (ii) any Assumed Liability.
   
            .3 RECOVERIES.  The amount of any Loss suffered or
   incurred by any person entitled to indemnification hereunder
   (an "Indemnified Person") shall be reduced by the amount of
   any insurance proceeds or other cash receipts paid to the

                                      -22-

<PAGE>


   Indemnified Person or any affiliate thereof as an offset
   against such Loss (and no right of subrogation shall accrue to
   any insurer hereunder), including any indemnification received
   by the Indemnified Person or such affiliate from an unrelated
   party with respect to such Loss.
   
            .4 CLAIMS.  An Indemnified Person shall promptly
   give the indemnifying party (an "Indemnifying Person") written
   notice of any matter which such Indemnified Person has
   determined has given rise to a right of indemnification under
   this Agreement, stating the amount of the Loss, if known, and
   method of computation thereof, all with reasonable
   particularity (subject to the last sentence of this
   paragraph).  The obligations and liabilities of any party
   under this Section 12 with respect to Losses arising from
   claims, assertions, events or proceedings of any third party
   (including, without limitation, claims by any assignee or
   successor of the Indemnified Person or any governmental
   agency), which are subject to the indemnification provided for
   in this Section 12 ("Third Party Claims") shall be governed by
   and be subject to the following additional terms and
   conditions:  if any Indemnified Person shall receive written
   notice of any Third Party Claim, the Indemnified Person shall
   give the Indemnifying Person prompt written notice of such
   Third Party Claim (subject to the last sentence of this
   paragraph) and shall permit the Indemnifying Person, at its
   option, to participate in the defense of such Third Party
   Claim by counsel of its own choosing and at its expense. 
   Furthermore, if the Indemnifying Person acknowledges in
   writing its obligation to indemnify the Indemnified Person
   hereunder against any Loss (without limitation) that may
   result from such Third Party Claim, then the Indemnifying
   Person shall be entitled, at its option, to assume and control
   the defense against such Third Party Claim at its expense and
   through counsel of its choice if it gives prompt written
   notice of its intention to do so to the Indemnified Person
   unless, in the reasonable opinion of counsel for the
   Indemnified Person, there is a conflict or a potential
   conflict of interests between the Indemnified Person and the
   Indemnifying Person in such action, suit or proceeding, in
   which event the Indemnified Person shall be entitled to direct
   the defense with respect to, but only with respect to, those
   issues with respect to which such conflict exists.  In the
   event the Indemnifying Person exercises its right to undertake

                                      -23-

<PAGE>


   the defense against any such Third Party Claim as provided
   above, the Indemnified Person shall, and it shall cause its
   affiliates to, cooperate with the Indemnifying Person in such
   defense and make available to the Indemnifying Person all
   pertinent records, materials and information in their
   possession or under their control relating thereto as is
   required by the Indemnifying Person.  No such Third Party
   Claim, except the settlement thereof which involves (i) the
   payment of money only for which any Indemnified Person is
   totally indemnified (without limitation) by the Indemnifying
   Person and (ii) the unconditional release from all related
   liability of the Indemnified Person, may be settled by the
   Indemnifying Person without the written consent of the
   Indemnified Person.  Any settlement of a Third Party Claim by
   an Indemnified Person without the written consent of the
   Indemnifying Person shall discharge the Indemnifying Person
   from all liability hereunder with respect to the subject
   matter of such Third Party Claim.  The foregoing
   notwithstanding, the failure of any Indemnified Person to give
   any notice required to be given hereunder shall not affect
   such Indemnified Person's right to indemnification hereunder
   except to the extent the Indemnifying Person from whom such
   indemnity is sought shall have been actually and materially
   prejudiced in its ability to defend the claim or action for
   which such indemnification is sought by reason of such
   failure.
   
       13.  TERMINATION.
   
            .1 TERMINATION.  This Agreement may be terminated
   by written notice from the party or parties indicated below
   under the following circumstances:
   
                    (i)    ADVERSE PROCEEDINGS.  By either Buyer

   injunction), decree or ruling or taken any other action
   restraining, enjoining or otherwise prohibiting any material

          FORM OF WARRANTS TO PURCHASE COMMON STOCK
                  OF ALLIANCE IMAGING, INC.

                     Warrant Certificate

     THIS CERTIFIES THAT _____________________________ ("Original Warrant
Holder") or registered assigns is the registered owner of the number of 
warrants set forth above (the "Warrants"), each of which entitles the owner
thereof to purchase, subject to the terms and conditions hereof, at any time
prior to 5:00 P.M. (Los Angeles time) on the Expiration Date (as hereinafter
defined) at the principal office of Alliance Imaging, Inc., a Delaware
corporation (the "Company"), one fully paid and non-assessable share of the
Common Stock, $.01 par value ("Common Stock"), of the Company, at a cash
purchase price which shall initially be $ 3.9375 per share (as such purchase
price may be adjusted pursuant to the terms hereof, the "Purchase Price") upon
presentation and surrender of this Warrant Certificate with the Form of
Election to Purchase duly executed and accompanied by payment of the Purchase
Price in the manner specified herein.  As provided herein, the Purchase Price
and the number of shares of Common Stock which may be purchased upon the 
exercise of the Warrants evidenced by this Warrant Certificate are, upon the
happening of certain events, subject to modification and adjustment.  The
holder or holders of these Warrants, whether the Original Warrant Holder or
registered assigns, shall be collectively referred to herein as the "Holder."

     1.  FORM OF WARRANT CERTIFICATES.  All certificates representing the
Warrants ("Warrant Certificates"), if any in addition to this Warrant
Certificate,

<PAGE>

which may hereinafter be issued and the forms of election to purchase shares 
and of assignment that accompany such Warrant Certificates shall be 
substantially in the form of this Warrant Certificate and may have such 
letters, numbers or other marks of identification or designation and such 
legends (including, without limitation, a legend referring to restrictions on 
resale by statutory underwriters), summaries or endorsements printed thereon 
as the Company may deem appropriate and as are not inconsistent with the 
provisions of this Warrant Certificate, or as may be required to comply with 
any law or with any rule or regulation made pursuant thereto.  All Warrant 
Certificates shall be executed on behalf of the Company by its President or a 
senior or executive vice president.

     2.  TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF WARRANT 
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN WARRANT CERTIFICATES.  
Subject to the provisions of Section 11 hereof, this Warrant Certificate may 
be transferred, split up, combined or exchanged for another Warrant 
Certificate or Warrant Certificates, entitling the Holder to purchase a like 
number of shares of Common Stock as the Warrant Certificate or Warrant 
Certificates surrendered then entitled him to purchase; provided, however, 
that (i) any Warrant Certificate with which this Warrant Certificate is 
combined shall have the same terms as this Warrant Certificate, and (ii) 
notwithstanding anything in this Warrant Certificate to the contrary, the 
Holder may transfer all or a portion of its right, title and interest in and 
to the Warrants to another person or entity.  If the Holder desires to 
transfer, split up, combine or exchange any Warrant Certificate, he or she 
shall make such request in writing delivered to the Company, and shall 
surrender the Warrant Certificate or Warrant Certificates to be transferred, 
split up, combined or exchanged at the principal office of the Company.  
Thereupon, the Company shall have such new Warrant Certificate or Warrant 
Certificates, as the case may be, signed as provided in Section 1 and 
delivered to the person entitled thereto, as so requested.  The Company may 
require payment by the Holder of a sum sufficient to cover any tax or 
governmental charge that may be imposed in connection with any transfer, 
split up, combination or exchange of Warrant Certificates.

     Upon receipt by the Company of evidence satisfactory to it of the loss, 
theft, destruction or mutilation of this Warrant Certificate, and, in case of 
loss, theft or destruction, of indemnity or security reasonably satisfactory 
to it (including with respect to the amount of such indemnity or security), 
and reimbursement by the Holder to the Company of all reasonable expenses 
incidental thereto, and upon surrender and cancellation of this Warrant 
Certificate if mutilated, the Company will make and deliver a new Warrant 
Certificate of like tenor to the Holder in lieu of the Warrant Certificate so 
lost, stolen, destroyed or mutilated.  Notwithstanding anything in the 
foregoing to the contrary, so long as the Holder is the Original Warrant 
Holder, the Company will not require security (other than its own 
indemnification referred to above) in connection with any such issuance of 
replacement Warrant Certificates.

                                   -2-

<PAGE>

     3.  SUBSEQUENT ISSUE OF WARRANT CERTIFICATES. Subsequent to the issuance 
of this Warrant Certificate, additional Warrant Certificates shall be issued, 
as necessary, in connection with (a) any transfer, combination, split up or 
exchange of Warrants pursuant to Section 2 hereof, (b) the replacement of 
mutilated, destroyed, lost or stolen Warrant Certificates pursuant to Section 
2 hereof, (c) the partial exercise of any Warrant Certificate to evidence the 
unexercised portion of such Warrant Certificate, pursuant to Section 4 
hereof, and (d) the exercise of the Company's election set forth in Section 
8(e) hereof.

    4.  EXERCISE OF WARRANTS; PURCHASE PRICE.

     (a)  Subject to the final sentence of this paragraph (a), the Holder of
this Warrant Certificate may exercise the Warrants evidenced hereby in whole or
in part at any time upon surrender of the Warrant Certificate with the form of
election to purchase attached hereto duly executed and accompanied by payment
of the Purchase Price for each share of Common Stock as to which the Warrants
are exercised, at or prior to 5:00 p.m. (Los Angeles time) on the Expiration
Date.  The "Expiration Date" shall be the date that is ten (10) years from the
date of the issuance of these Warrants.  The Purchase Price shall initially be
$3.9375 but shall be subject to adjustment as provided in Section 8 hereof, and
shall be payable only in the consideration specified in paragraph (b)
immediately below.

     (b)  Upon receipt of this Warrant Certificate, with the form of election
to purchase duly executed, accompanied by payment, in cash, or by certified
check or bank draft payable to the order of the Company, or by surrender of a
debt instrument of the Company held by the Holder (valued at the outstanding
principal amount thereof plus, at the option of the Holder, any accrued and
unpaid interest thereon) or a preferred stock instrument of the Company held by
the Holder (valued at the liquidation preference thereof, including, without
duplication, at the option of the Holder, any accumulated and unpaid dividends
thereon), of the Purchase Price for the shares to be purchased and an amount
equal to any applicable transfer tax, if any, the Company shall thereupon
promptly deliver to or upon the order of the Holder of a Warrant Certificate
(i) certificates for the number of whole shares of Common Stock to be
purchased, registered in such name or names as may be designated by the Holder
and (ii) when appropriate, the amount of cash to be paid in lieu of issuance of
fractional shares.

     (c)  In case the Holder of this Warrant Certificate shall exercise less
than all the Warrants evidenced hereby, a new Warrant Certificate evidencing
Warrants equivalent to the Warrants remaining unexercised shall be issued by
the Company to the Holder or to his duly authorized assigns, subject to the
provisions of Section 11 hereof.  In addition, if the Holder exercises Warrants
using debt or preferred stock instruments of the Company as hereinabove

                                   -3-

<PAGE>

provided, the Company shall return balance certificates representing such 
instruments to the Holder unless the full amount of such instruments is 
tendered as payment of the Purchase Price.

     (d)  All shares of Common Stock issued upon the exercise of Warrants 
shall be deemed to be Registrable Securities within the meaning of that 
certain Registration Rights Agreement dated as of December 31, 1994 among the 
Company and the Noteholders and Debentureholders named therein, with the same 
registration and other rights afforded to other Registrable Securities 
covered thereby.

     5.  CANCELLATION AND DESTRUCTION OF WARRANT CERTIFICATE.  Upon surrender 
of this Warrant Certificate for the purpose of exercise (in whole or in 
part), exchange, substitution or transfer, this Warrant Certificate shall be 
cancelled, and no Warrant Certificates shall be issued in lieu thereof except 
as expressly permitted by any of the provisions of this Warrant Certificate. 
If the Company purchases or acquires Warrants, the Company shall cancel and 
retire the Warrant Certificates evidencing such Warrants.

     6.  RESERVATION AND AVAILABILITY OF SHARES OF COMMON STOCK.  The Company 
covenants and agrees that it will cause to be reserved and kept available out 
of its authorized and unissued shares of Common Stock, the number of shares 
of Common Stock that will be sufficient to permit the exercise in full of all 
outstanding Warrants.

     The Company covenants and agrees that it will take all such action as 
may be necessary to ensure that all shares of Common Stock delivered upon the 
exercise of Warrants shall, at the time of delivery of the certificates for 
such shares (subject to payment of the Purchase Price and compliance with all 
other provisions of this Warrant Certificate), be duly and validly authorized 
and issued and fully paid and nonassessable shares.

     The Company further covenants and agrees that it will pay when due and 
payable any and all federal and state transfer taxes and charges which may be 
payable in respect of the issuance or delivery of Warrant Certificates or of 
any shares of Common Stock upon the exercise of Warrants.  The Company shall 
not, however, be required (i) to pay any tax or taxes based upon the income 
of the Holder or any tax or taxes which may be payable in respect of any 
transfer involved in the transfer or delivery of Warrant Certificates or the 
issuance or delivery of certificates for Common Stock in a name other than 
that of the Holder or (ii) to issue or deliver any certificates for shares of 
Common Stock upon the exercise of any Warrants until any such tax shall have 
been paid (any such tax being payable by the Holder of the Warrant 
Certificate at the time of surrender) or until it has been established to the 
Company's satisfaction that no such tax is due.

                                   -4-

<PAGE>

     7.  COMMON STOCK RECORD DATE.  Each person in whose name any certificate 
for shares of Common Stock is issued upon the exercise of the Warrants shall 
for all purposes be deemed to have become the holder of record of the Common 
Stock represented thereby, and such certificate shall be dated on the 
exercise date, which is the date upon which the Warrant Certificate 
evidencing such Warrants was duly surrendered and payment of the Purchase 
Price (and any applicable transfer taxes) was made; PROVIDED, HOWEVER, that 
if such exercise date is a date upon which the Common Stock transfer books of 
the Company are closed, such person shall be deemed to have become the record 
holder of such shares on, and such certificate shall be dated, the next 
succeeding business day on which the Common Stock transfer books of the 
Company are open.

     The Holder, as such, shall not be entitled to vote or receive dividends 
or be deemed for any purpose the holder of Common Stock or of any other 
securities of the Company which may at any time be issuable on the exercise 
of the Warrants, nor shall anything contained in this Warrant Certificate be 
construed to confer upon the Holder, as such, any of the rights of a 
shareholder of the Company or any right to vote upon any matter submitted to 
shareholders at any meeting thereof, or to give or withhold consent to any 
corporate action (whether upon any recapitalization, issuance of stock, 
reclassification of stock, change of par value, consolidation, merger, 
conveyance, or otherwise) or to receive notice of meetings, or to receive 
dividends or subscription rights or otherwise, until the Warrants shall have 
been exercised as provided in this Warrant Certificate.

     8.  ADJUSTMENT OF PURCHASE PRICE, NUMBER OF SHARES OR NUMBER OF 
WARRANTS. The Purchase Price and the number of shares covered by this Warrant 
Certificate are subject to adjustment from time to time upon the occurrence 
of the events enumerated in this Section 8.

     (a)  In case the Company shall at any time after the date of the 
issuance of this Warrant Certificate (i) declare a dividend on the Common 
Stock payable in shares of Common Stock, (ii) subdivide the outstanding 
Common Stock into a greater number of shares, (iii) combine the outstanding 
Common Stock into a smaller number of shares, or (iv) issue any shares of its 
capital stock in a reclassification of the Common Stock (including any such 
reclassification in connection with a consolidation or merger), the Purchase 
Price in effect at the time of the record date for such dividend, or such 
issuance,  or of the effective date of such subdivision, combination, 
distribution or reclassification, and the number and kind of shares of 
capital stock issuable on such date shall be proportionately adjusted so that 
upon the exercise after such time of any Warrant, the Holder shall be 
entitled to receive the aggregate number and kind of shares of capital stock 
which, if such Warrant had been exercised immediately prior to such date and 
at a time when the Common Stock transfer books of the Company were open, the 
Holder would have owned

                                   -5-
                                  
<PAGE>

upon such exercise and been entitled to receive by virtue of such dividend, 
subdivision, combination, distribution or reclassification, subject to the 
provisions of Section 8(c) hereof.  Such adjustment shall be made 
successively whenever any event listed above shall occur.

     (b)  In case after the date hereof the Company shall (except as 
hereinafter provided) issue any Additional Securities for a consideration 
less than (a) the then effective per share Purchase Price or (b) the Fair 
Market Value per share, then the per share Purchase Price upon each such 
issuance shall be adjusted to that price determined by multiplying the per 
share Purchase Price in effect immediately prior to such event by a fraction:

          (A)  if issued for a consideration per share less than the then 
effective per share Purchase Price:

               (1)  the numerator of which shall be the number of Outstanding 
Shares (as hereinafter defined) immediately prior to the issuance of such 
Additional Securities PLUS the number of shares of Common Stock which the 
aggregate consideration for the total number of such Additional Securities so 
issued would purchase at the then effective per share Purchase Price, and

               (2)  the denominator of which shall be the number of 
Outstanding Shares immediately after the issuance of such Additional 
Securities.

          (B)  if issued for a consideration per share less than the Fair 
Market Value per share of Common Stock:

               (1)  the numerator of which shall be the number of Outstanding 
Shares immediately prior to the issuance of such Additional Securities plus 
the number of shares of Common Stock which the aggregate consideration for 
the total number of such Additional Securities so issued would purchase at 
the Fair Market Value per share; and

               (2)  the denominator of which shall be the number of 
Outstanding Shares immediately after the issuance of such Additional 
Securities.

     If such additional Securities shall be issued at a price per share less 
than both the then effective per share Purchase Price and the Fair Market 
Value per share of Common Stock, the per share Purchase Price shall be 
adjusted in the manner which will result in a greatest reduction of the per 
share Purchase Price.  The provisions of this Section 8(b) shall not apply to 
any Additional Securities which are distributed to holders of Common Stock as 
a stock dividend or subdivision, for which an adjustment is provided for 
under Section 8(a). Such

                                   -6-

<PAGE>

adjustment shall be made successively whenever Additional Securities are 
issued, subject to Section 8(c) hereof.

          (i)  "Additional Securities" shall mean (A) shares of Common Stock 
and (B) options, warrants or rights to purchase Common Stock or securities 
convertible into or exchangeable for Common Stock ("Derivative Securities"); 
provided, however, that Additional Securities shall not include (A) shares of 
Common Stock issued upon exercise of any warrants, options or rights issued 
or granted on or prior to April 15, 1996 and any warrant certificates or 
similar instruments issued upon transfer, split up, combination or exchange 
of any of such warrants, options or rights, (B) Derivative Securities granted 
by the Company prior to the issuance date of these Warrants, (C) Derivative 
Securities granted to any investor in debt securities of the Company in order 
to induce such investor to purchase such debt securities, provided that such 
Derivative Securities represent the right to acquire not more than five 
percent (5%) of the Outstanding Shares in the aggregate, and the Common Stock 
issuable upon the exercise or conversion thereof or exchange therefor, (D) 
options to acquire Common Stock issued pursuant to a compensatory plan duly 
approved by the Board of Directors of the Company, and (E) shares of Common 
Stock issued in a secondary offering registered under the Securities Act of 
1933, as amended, provided that the public offering price in such offering is 
not less than 95% of the Fair Market Value of the Common Stock.

          (ii) "Consideration" shall mean (A) all consideration received by 
the Company upon the issuance or sale of Additional Securities and (B) the 
minimum amounts of consideration payable to the Company upon the exercise, 
conversion or exchange of any Derivative Securities that are Additional 
Securities.  For the purpose of calculating Consideration, the consideration 
received by the Company for any issue or sale of securities shall (A) to the 
extent it consists of cash, be computed at the net amount of cash received by 
the Company after any deduction of any expenses payable by the Company and 
any underwriting or similar commissions, compensation, or concessions paid or 
allowed by the Company in connection with such issue or sale, (B) to the 
extent it consists of property other than cash, be computed at the fair value 
of that property as determined in good faith by the Board of Directors of the 
Company, and (C) if Additional Securities are issued or sold together with 
other stock or securities or other assets of the Company for a consideration 
which covers both, be computed as the portion of the consideration so 
received that may be reasonably determined in good faith by the Board of 
Directors to be allocable to such Additional Securities.

          (iii)       "Outstanding Shares" shall, at any given time, mean (A) 
all shares of Common Stock outstanding at such time and (B) all shares of 
Common Stock that could be acquired through the exercise, conversion or 
exchange of Derivative Securities that are outstanding at such time.

                                   -7-
<PAGE>

          (iv)  "Fair Market Value" means, as of any date of determination, 
the closing sale price of the Common Stock on the principal national 
securities exchange on which the Common Stock is then traded on the last 
preceding trading day on which the Common Stock was traded (the "Last Trading 
Day"), or, if the Common Stock is not traded on a national securities 
exchange, the closing sale price of the Common Stock on the National Market 
System of NASDAQ on the Last Trading Day, or, if the Common Stock is not 
traded on a national securities exchange or the National Market System, the 
average of the last bid and asked prices of the Common Stock on the Small Cap 
market of the NASDAQ on the Last Trading Day, or, if the Common Stock is not 
then traded on any of the foregoing markets, the value of the Common Stock 
determined by the Board of Directors of the Company in good faith.  
Notwithstanding the foregoing, in the event that Additional Securities are 
issued pursuant to a private placement, Fair Market Value shall mean the 
average of the amounts described above on each of the 10 trading days 
immediately preceding the determination date.

          (v)  No adjustment of the Purchase Price under this Section 8(b) 
shall be made as a result of the actual issuance of Common Stock upon the 
exercise, conversion or exchange of any Derivative Securities, other than the 
adjustment made upon the issuance or sale of any such Derivative Securities. 
If an adjustment has been made upon the issuance or sale of Derivative 
Securities and the rights to acquire Common Stock under such Derivative 
Securities shall expire without having been exercised, the Purchase Price 
adjusted upon the issuance of such Derivative Securities shall be readjusted 
to the Purchase Price which would have been in effect had an adjustment been 
made on the basis that the only Additional Securities so issued were the 
shares of Common Stock, if any, actually issued or sold on the exercise, 
conversion or exchange of such Derivative Securities, and such shares of 
Common Stock, if any, were issued or sold for the consideration actually 
received by the Company for the granting of all such Derivative Securities, 
plus the consideration, if any, actually received by the Company upon the 
exercise or conversion or exchange of such Derivative Securities.

     (c)  Notwithstanding anything in this Section 8 to the contrary, no 
adjustment in the Purchase Price shall be required unless such adjustment, 
together with any amount being carried forward as hereinafter provided, would 
require an increase or decrease of at least 1% in such price; provided, 
however, that any adjustments which by reason of this Section 8(c) are not 
required to be made shall be carried forward and taken into account in any 
subsequent adjustment.  All calculations under this Section 8 shall be made 
to the nearest cent or to the nearest one-hundredth of a share, as the case 
may be.  Notwithstanding the first sentence of this Section 8(c), any 
adjustment required by this Section 8 shall be made no later than the earlier 
of one year from the date of the transaction which mandates such adjustment 
or the expiration of the right to exercise any Warrant.

                                   -8-

<PAGE>

     (d)  In the event that at any time, as a result of an adjustment made 
pursuant to Section 8(a) hereof, the Holder shall become entitled to receive 
any shares or units of capital stock of the Company other than shares of 
Common Stock upon the exercise or conversion of Warrants, thereafter the 
number of such other shares or units so receivable upon exercise of the 
Warrants shall be subject to adjustment from time to time in a manner and on 
terms as nearly equivalent as  practicable to the provisions with respect to 
the Common Stock contained in Section 8(a) hereof, and the provisions of this 
Warrant Certificate with respect to the shares of Common Stock shall apply on 
like terms to any such other shares or units.

     (e)  Irrespective of any adjustments in the Purchase Price or the number 
of shares of Common Stock issuable upon the exercise of Warrants, this 
Warrant Certificate or Warrant Certificates thereafter issued may continue to 
express the Purchase Price and the number of shares stated in this Warrant 
Certificate and the Purchase Price and such number of shares specified 
thereon shall be deemed to have been so adjusted.

     (f)  Upon each adjustment of the Purchase Price as a result of the 
calculations made in Section 8(b) hereof, each Warrant outstanding 
immediately prior to the making of such adjustment shall thereafter be deemed 
to evidence the right to purchase, at the adjusted Purchase Price, that 
number of shares (calculated to the nearest one-hundredth) obtained by (i) 
multiplying the number of shares covered by a Warrant immediately prior to 
the adjustment of the number of shares by the Purchase Price in effect 
immediately prior to such adjustment of the Purchase Price and (ii) dividing 
the product so obtained by the Purchase Price in effect immediately after 
such adjustment of the Purchase Price.

     (g)  The Company may elect to adjust the number of Warrants, in 
substitution for any adjustment in the number of shares of Common Stock 
purchasable upon the exercise of the Warrants as provided in Section 8(a) 
hereof, such that the total number of shares of Common Stock issuable upon 
exer cise of the Warrants is the same as if such adjustment had been made but 
such that each of the Warrants outstanding after such adjustment of the 
number of Warrants is exercisable for one share of Common Stock.  The Company 
shall notify the Holder in writing of such election.  Upon each adjustment of 
the number of Warrants pursuant to this subsection (g), the Company shall as 
promptly as practicable cause to be distributed to the Holder Warrant 
Certificates evidencing, subject to Section 11, the additional or substitute 
Warrants to which the Holder shall be entitled as a result of such 
adjustment; or, at the option of the Company, shall cause to be distributed 
to the Holder in substitution and replacement for the Warrant Certificates 
held by the Holder prior to the date of adjustment, and upon surrender 
thereof, if required by the Company, new Warrant Certificates evidencing all 
the Warrants

                                   -9-

<PAGE>

to which the Holder shall be entitled after such adjustment.  
Warrant Certificates so to be distributed shall be issued in the manner 
provided for herein (and shall bear the adjusted Purchase Price, if 
applicable) and shall be registered in the name of the Holder.

     (h)  In any case in which this Section 8 shall require that an adjustment
in the Purchase Price be made effective as of a record date for a specified
event, the Company may elect to defer until the occurrence of such event the
issuing to the Holder of any Warrant exercised after such record date the
shares of Common Stock and other capital stock of the Company, if any, issuable
upon such exercise over and above the shares of Common Stock and other capital
stock of the Company, if any, issuable upon such exercise on the basis of the
Purchase Price in effect prior to such adjustment; PROVIDED, HOWEVER, that the
Company shall deliver to the Holder a due bill or other appropriate instrument
evidencing the Holder's right to receive such additional shares upon the
occurrence of the event requiring such adjustment.

     9.  CERTIFICATION OF ADJUSTED PURCHASE PRICE AND NUMBER OF SHARES 
ISSUABLE.  Whenever the Purchase Price and the number of shares of Common 
Stock issuable upon the exercise of each Warrant are adjusted as provided in 
Section 8 above, the Company shall provide notice to the Holder in writing 
setting forth the Purchase Price as so adjusted, the number of shares of 
Common Stock issuable upon the exercise of each Warrant as so adjusted, and a 
brief statement of the facts accounting for such adjustment to the Holder.  
Failure to give such notice, or any defect therein, shall not affect the 
legality or validity of any action referred to in Section 8 hereof.

     10.  CONSOLIDATION, MERGER OR SALE OF ASSETS.  If (i) the Company shall 
at any time consolidate with or merge with or into another corporation and 
(ii) the Common Stock is exchanged, cancelled or reclassified in connection 
with such transaction, the Holder will thereafter receive, upon the exercise 
hereof in accordance with the terms of this Agreement, the securities, 
property or cash to which the holder of the number of shares of Common Stock 
deliverable upon the exercise of the Warrants immediately prior to such 
transaction would have been entitled upon such consolidation or merger, and 
the Company shall take such steps in connection with such consolidation or 
merger as may be necessary to assure that the provisions hereof shall 
thereafter be applicable, as nearly as reasonably may be, in relation to any 
securities or property thereafter deliverable upon the exercise of the 
Warrants.  A sale or lease of all or substantially all the assets of the 
Company for a consideration (apart from the assumption of obligations) 
consisting primarily of securities shall be deemed a consolidation or merger 
for the purposes of clause (i) of the first sentence of this Section 10.  The 
provisions of this Section 10 shall similarly apply to successive mergers or 
consolidations or sales or other transfers.

                                   -10-

<PAGE>

     11.  FRACTIONAL WARRANTS AND FRACTIONAL SHARES.

     (a)  Notwithstanding an adjustment pursuant to Section 8(e) hereof in 
the number of Warrants, the Company shall not be required to issue Warrant 
Certificates which evidence fractional Warrants.  If the Company so elects, 
in lieu of such fractional Warrants, there shall be paid to the Holder to 
whom such fractional Warrants would otherwise be issuable, an amount in cash 
equal to the same fraction of the current market value of a whole Warrant (as 
determined in good faith by the Board of Directors of the Company).

     (b)  Notwithstanding an adjustment pursuant to Section 8(a) hereof in 
the number of shares covered by a Warrant, the Company shall not be required 
to issue fractions of shares upon exercise of the Warrants or to distribute 
certificates which evidence fractional shares.  In lieu of fractional shares, 
at the Company's election, there shall be paid to the Holder at the time 
Warrants are exercised as herein provided an amount in cash equal to the same 
fraction of the current market value of a share of Common Stock (as 
determined in good faith by the Board of Directors of the Company).

     (c)  The Holder, by the acceptance of the Warrant, expressly waives his 
right to receive any fractional Warrant or any fractional share upon exercise 
of a Warrant.

     12.  RIGHT OF ACTION.  All rights of action in respect of this Warrant 
Certificate are vested in the Holder.

     13.  AGREEMENT OF WARRANT CERTIFICATE HOLDERS. The Holder of this 
Warrant Certificate by accepting the same consents and agrees with the

                       WARRANTS TO PURCHASE COMMON STOCK
                           OF ALLIANCE IMAGING, INC.

                              Warrant Certificate

     THIS CERTIFIES THAT _____________________________ ("Original Warrant
Holder") or registered assigns is the registered owner of the number of 
warrants set forth above (the "Warrants"), each of which entitles the owner
thereof to purchase, subject to the terms and conditions hereof, at any time
prior to 5:00 P.M. (Los Angeles time) on the Expiration Date (as hereinafter
defined) at the principal office of Alliance Imaging, Inc., a Delaware
corporation (the "Company"), one fully paid and non-assessable share of the
Common Stock, $.01 par value ("Common Stock"), of the Company, at a cash
purchase price which shall initially be $5.00 per 

<PAGE>

share (as such purchase price may be adjusted pursuant to the terms hereof, 
the "Purchase Price") upon presentation and surrender of this Warrant 
Certificate with the Form of Election to Purchase duly executed and 
accompanied by payment of the Purchase Price in the manner specified herein.  
As provided herein, the Purchase Price and the number of shares of Common 
Stock which may be purchased upon the exercise of the Warrants evidenced by 
this Warrant Certificate are, upon the happening of certain events, subject 
to modification and adjustment.  The holder or holders of these Warrants, 
whether the Original Warrant Holder or registered assigns, shall be 
collectively referred to herein as the "Holder."

      1.  FORM OF WARRANT CERTIFICATES.  All certificates representing the
Warrants ("Warrant Certificates"), if any in addition to this Warrant
Certificate, which may hereinafter be issued and the forms of election to
purchase shares and of assignment that accompany such Warrant Certificates
shall be substantially in the form of this Warrant Certificate and may have
such letters, numbers or other marks of identification or designation and such
legends (including, without limitation, a legend referring to restrictions on
resale by statutory underwriters), summaries or endorsements printed thereon as
the Company may deem appropriate and as are not inconsistent with the
provisions of this Warrant Certificate, or as may be required to comply with
any law or with any rule or regulation made pursuant thereto.  All Warrant
Certificates shall be executed on behalf of the Company by its President or a
senior or executive vice president.

     2.  TRANSFER, SPLIT UP, COMBINATION AND EXCHANGE OF WARRANT CERTIFICATES;
MUTILATED, DESTROYED, LOST OR STOLEN WARRANT CERTIFICATES.  Subject to the
provisions of Section 11 hereof, this Warrant Certificate may be transferred,
split up, combined or exchanged for another Warrant Certificate or Warrant
Certificates, entitling the Holder to purchase a like number of shares of
Common Stock as the Warrant Certificate or Warrant Certificates surrendered
then entitled him to purchase; provided, however, that (i) any Warrant
Certificate with which this Warrant Certificate is combined shall have the same
terms as this Warrant Certificate, and (ii) notwithstanding anything in this
Warrant Certificate to the contrary, the Holder may transfer all, but not less
than all, of its right, title and interest in and to the Warrants to 

                                     -2-

<PAGE>

another person or entity.  If the Holder desires to transfer, split up, 
combine or exchange any Warrant Certificate, he or she shall make such 
request in writing delivered to the Company, and shall surrender the Warrant 
Certificate or Warrant Certificates to be transferred, split up, combined or 
exchanged at the principal office of the Company.  Thereupon, the Company 
shall have such new Warrant Certificate or Warrant Certificates, as the case 
may be, signed as provided in Section 1 and delivered to the person entitled 
thereto, as so requested.  The Company may require payment by the Holder of a 
sum sufficient to cover any tax or governmental charge that may be imposed in 
connection with any transfer, split up, combination or exchange of Warrant 
Certificates.

     Upon receipt by the Company of evidence satisfactory to it of the loss,
theft, destruction or mutilation of this Warrant Certificate, and, in case of
loss, theft or destruction, of indemnity or security reasonably satisfactory to
it (including with respect to the amount of such indemnity or security), and
reimbursement by the Holder to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of this Warrant
Certificate if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor to the Holder in lieu of the Warrant Certificate so
lost, stolen, destroyed or mutilated.  In requesting a substitute Warrant
Certificate the Holder shall also comply with  such other regulations and pay
such other reasonable charges as the Company may prescribe.

     3.  SUBSEQUENT ISSUE OF WARRANT CERTIFICATES. Subsequent to the issuance
of this Warrant Certificate, additional Warrant Certificates shall be issued,
as necessary, in connection with (a) any transfer, combination, split up or
exchange of Warrants pursuant to Section 2 hereof, (b) the replacement of
mutilated, destroyed, lost or stolen Warrant Certificates pursuant to Section 2
hereof, (c) the partial exercise of any Warrant Certificate to evidence the
unexercised portion of such Warrant Certificate, pursuant to Section 4 hereof,
and (d) the exercise of the Company's election set forth in Section 8(e)
hereof.

                                     -3-

<PAGE>

     4.  EXERCISE OF WARRANTS; PURCHASE PRICE.

     (a)  Subject to the final sentence of this paragraph (a), the Holder of
this Warrant Certificate may exercise the Warrants evidenced hereby in whole or
in part at any time upon surrender of the Warrant Certificate with the form of
election to purchase attached hereto duly executed and accompanied by payment
of the Purchase Price for each share of Common Stock as to which the Warrants
are exercised, at or prior to 5:00 p.m. (Los Angeles time) on the Expiration
Date.  The "Expiration Date" shall be the date that is four (4) years from the
date of the issuance of these Warrants.  The Purchase Price shall initially be
$5.00 but shall be subject to adjustment as provided in Section 8 hereof, 
and shall be payable only in the consideration specified in paragraph 
(b) immediately below.

     (b)  Upon receipt of this Warrant Certificate, with the form of election
to purchase duly executed, accompanied by payment, in cash, or by certified
check or bank draft payable to the order of the Company, of the Purchase Price
for the shares to be purchased and an amount equal to any applicable transfer
tax, if any, the Company shall thereupon promptly deliver to or upon the order
of the Holder of a Warrant Certificate (i) certificates for the number of whole
shares of Common Stock to be purchased, registered in such name or names as may
be designated by the Holder and (ii) when appropriate, the amount of cash to be
paid in lieu of issuance of fractional shares.

     (c)  In case the Holder of this Warrant Certificate shall exercise less
than all the Warrants evidenced hereby, a new Warrant Certificate evidencing
Warrants equivalent to the Warrants remaining unexercised shall be issued by
the Company to the Holder or to his duly authorized assigns, subject to the
provisions of Section 11 hereof.

     5.  CANCELLATION AND DESTRUCTION OF WARRANT CERTIFICATE.  Upon surrender
of this Warrant Certificate for the purpose of exercise (in whole or in part),
exchange, substitution or transfer, this Warrant Certificate shall be
cancelled, and no Warrant Certificates shall be issued in lieu thereof except
as expressly permitted by any of the provisions of this Warrant Certificate.
If the Company purchases or acquires Warrants, 

                                     -4-

<PAGE>

the Company may cancel and retire the Warrant Certificates evidencing such 
Warrants.

     6.  RESERVATION AND AVAILABILITY OF SHARES OF COMMON STOCK.  The Company
covenants and agrees that it will cause to be reserved and kept available out
of its authorized and unissued shares of Common Stock, the number of shares of
Common Stock that will be sufficient to permit the exercise in full of all
outstanding Warrants.

     The Company covenants and agrees that it will take all such action as may
be necessary to ensure that all shares of Common Stock delivered upon the
exercise of Warrants shall, at the time of delivery of the certificates for
such shares (subject to payment of the Purchase Price and compliance with all
other provisions of this Warrant Certificate), be duly and validly authorized
and issued and fully paid and nonassessable shares.

     The Company further covenants and agrees that it will pay when due and
payable any and all federal and state transfer taxes and charges which may be
payable in respect of the issuance or delivery of Warrant Certificates or of
any shares of Common Stock upon the exercise of Warrants.  The Company shall
not, however, be required (i) to pay any tax or taxes based upon the income of
the Holder or any tax or taxes which may be payable in respect of any transfer
involved in the transfer or delivery of Warrant Certificates or the issuance or
delivery of certificates for Common Stock in a name other than that of the
Holder or (ii) to issue or deliver any certificates for shares of Common Stock
upon the exercise of any Warrants until any such tax shall have been paid (any
such tax being payable by the Holder of the Warrant Certificate at the time of
surrender) or until it has been established to the Company's satisfaction that
no such tax is due.

     7.  COMMON STOCK RECORD DATE.  Each person in whose name any certificate
for shares of Common Stock is issued upon the exercise of the Warrants shall
for all purposes be deemed to have become the holder of record of the Common
Stock represented thereby, and such certificate shall be dated on the exercise
date, which is the date upon which the Warrant Certificate evidencing such
Warrants was duly surrendered and payment of the Purchase Price (and any
applicable transfer 

                                     -5-

<PAGE>

taxes) was made; PROVIDED, HOWEVER, that if such exercise date is a date upon 
which the Common Stock transfer books of the Company are closed, such person 
shall be deemed to have become the record holder of such shares on, and such 
certificate shall be dated, the next succeeding business day on which the 
Common Stock transfer books of the Company are open.

     The Holder, as such, shall not be entitled to vote or receive dividends or
be deemed for any purpose the holder of Common Stock or of any other securities
of the Company which may at any time be issuable on the exercise of the
Warrants, nor shall anything contained in this Warrant Certificate be construed
to confer upon the Holder, as such, any of the rights of a shareholder of the
Company or any right to vote upon any matter submitted to shareholders at any
meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock, change of par value, consolidation, merger, conveyance, or otherwise) or
to receive notice of meetings, or to receive dividends or subscription rights
or otherwise, until the Warrants shall have been exercised as provided in this
Warrant Certificate.

     8.  ADJUSTMENT OF PURCHASE PRICE, NUMBER OF SHARES OR NUMBER OF WARRANTS.
The Purchase Price and the number of shares covered by this Warrant Certificate
are subject to adjustment from time to time upon the occurrence of the events
enumerated in this Section 8.

          In case the Company shall at any time after the date of the issuance
of this Warrant Certificate (i) declare a dividend on the Common Stock payable
in shares of Common Stock, (ii) subdivide the outstanding Common Stock into a
greater number of shares, (iii) combine the outstanding Common Stock into a
smaller number of shares, or (iv) issue any shares of its capital stock in a
reclassification of the Common Stock (including any such reclassification in
connection with a consolidation or merger), the Purchase Price in effect at the
time of the record date for such dividend, or such issuance,  or of the
effective date of such subdivision, combination, distribution or
reclassification, and the number and kind of shares of capital stock issuable
on such date shall be proportionately adjusted so that upon the exercise after
such time of any Warrant, the Holder shall be entitled to receive the 

                                     -6-

<PAGE>

aggregate number and kind of shares of capital stock which, if such Warrant 
had been exercised immediately prior to such date and at a time when the 
Common Stock transfer books of the Company were open, the Holder would have 
owned upon such exercise and been entitled to receive by virtue of such 
dividend, subdivision, combination, distribution or reclassification, subject 
to the provisions of Section 8(b) hereof.  Such adjustment shall be made 
successively whenever any event listed above shall occur.

     (b)  Notwithstanding anything in this Section 8 to the contrary, no
adjustment in the Purchase Price shall be required unless such adjustment,
together with any amount being carried forward as hereinafter provided, would
require an increase or decrease of at least 1% in such price; provided,
however, that any adjustments which by reason of this Section 8(b) are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment.  All calculations under this Section 8 shall be made to
the nearest cent or to the nearest one-hundredth of a share, as the case may
be.  Notwithstanding the first sentence of this Section 8(b), any adjustment
required by this Section 8 shall be made no later than the earlier of one year
from the date of the transaction which mandates such adjustment or the
expiration of the right to exercise any Warrant.

     (c)  In the event that at any time, as a result of an adjustment made
pursuant to Section 8(a) hereof, the Holder shall become entitled to receive
any shares or units of capital stock of the Company other than shares of Common
Stock upon the exercise or conversion of Warrants, thereafter the number of
such other shares or units so receivable upon exercise of the Warrants shall be
subject to adjustment from time to time in a manner and on terms as nearly
equivalent as  practicable to the provisions with respect to the Common Stock
contained in Section 8(a) hereof, and the provisions of this Warrant
Certificate with respect to the shares of Common Stock shall apply on like
terms to any such other shares or units.

     (d)  Irrespective of any adjustments in the Purchase Price or the number
of shares of Common Stock issuable upon the exercise of Warrants, this Warrant
Certificate or Warrant Certificates thereafter issued may continue to express
the Purchase Price and the number of shares stated in this Warrant 

                                     -7-

<PAGE>

Certificate and the Purchase Price and such number of shares specified 
thereon shall be deemed to have been so adjusted.

     (e)  The Company may elect to adjust the number of Warrants, in 
substitution for any adjustment in the number of shares of Common Stock 
purchasable upon the exercise of the Warrants as provided in Section 8(a) 
hereof, such that the total number of shares of Common Stock issuable upon 
exercise of the Warrants is the same as if such adjustment had been made but 
such that each of the Warrants outstanding after such adjustment of the 
number of Warrants is exercisable for one share of Common Stock.  The Company 
shall notify the Holder in writing of such election.  Upon each adjustment of 
the number of Warrants pursuant to this subsection (e), the Company shall as 
promptly as practicable cause to be distributed to the Holder Warrant 
Certificates evidencing, subject to Section 11, the additional or substitute 
Warrants to which the Holder shall be entitled as a result of such 
adjustment; or, at the option of the Company, shall cause to be distributed 
to the Holder in substitution and replacement for the Warrant Certificates 
held by the Holder prior to the date of adjustment, and upon surrender 
thereof, if required by the Company, new Warrant Certificates evidencing all 
the Warrants to which the Holder shall be entitled after such adjustment.  
Warrant Certificates so to be distributed shall be issued in the manner 
provided for herein (and shall bear the adjusted Purchase Price, if 
applicable) and shall be registered in the name of the Holder.

     (f)  In any case in which this Section 8 shall require that an adjustment
in the Purchase Price be made effective as of a record date for a specified
event, the Company may elect to defer until the occurrence of such event the
issuing to the Holder of any Warrant exercised after such record date the
shares of Common Stock and other capital stock of the Company, if any, issuable
upon such exercise over and above the shares of Common Stock and other capital
stock of the Company, if any, issuable upon such exercise on the basis of the
Purchase Price in effect prior to such adjustment; PROVIDED, HOWEVER, that the
Company shall deliver to the Holder a due bill or other appropriate instrument
evidencing the Holder's right to receive such additional shares upon the
occurrence of the event requiring such adjustment.

                                     -8-

<PAGE>

      9.  CERTIFICATION OF ADJUSTED PURCHASE PRICE AND NUMBER OF SHARES
ISSUABLE.  Whenever the Purchase Price and the number of shares of Common Stock
issuable upon the exercise of each Warrant are adjusted as provided in
Section 8 above, the Company shall provide notice to the Holder in writing
setting forth the Purchase Price as so adjusted, the number of shares of Common
Stock issuable upon the exercise of each Warrant as so adjusted, and a brief
statement of the facts accounting for such adjustment to the Holder.  Failure
to give such notice, or any defect therein, shall not affect the legality or
validity of any action referred to in Section 8 hereof.

     10.  CONSOLIDATION, MERGER OR SALE OF ASSETS.  If (i) the Company shall at
any time consolidate with or merge with or into another corporation and
(ii) the Common Stock is exchanged, cancelled or reclassified in connection
with such transaction, the Holder will thereafter receive, upon the exercise
hereof in accordance with the terms of this Agreement, the securities, property
or cash to which the holder of the number of shares of Common Stock deliverable
upon the exercise of the Warrants immediately prior to such transaction would
have been entitled upon such consolidation or merger, and the Company shall
take such steps in connection with such consolidation or merger as may be
necessary to assure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to any securities or property
thereafter deliverable upon the exercise of the Warrants.  A sale or lease of
all or substantially all the assets of the Company for a consideration (apart
from the assumption of obligations) consisting primarily of securities shall be
deemed a consolidation or merger for the purposes of clause (i) of the first
sentence of this Section 10.  The provisions of this Section 10 shall similarly
apply to successive mergers or consolidations or sales or other transfers.

     11.  FRACTIONAL WARRANTS AND FRACTIONAL SHARES.

     (a)  Notwithstanding an adjustment pursuant to Section 8(e) hereof in the
number of Warrants, the Company shall not be required to issue Warrant
Certificates which evidence fractional Warrants.  If the Company so elects, in
lieu of such fractional Warrants, there shall be paid to the Holder to whom
such fractional Warrants would otherwise be issuable, an amount in cash equal
to the same fraction of the current market value of a whole Warrant (as
determined in good faith by the Board of Directors of the Company).

     (b)  Notwithstanding an adjustment pursuant to Section 8(a) hereof in the
number of shares covered by a Warrant, the Company shall not be required to
issue fractions of shares upon exercise of the Warrants or to distribute
certificates which evidence fractional shares.  In lieu of fractional shares,
at the Company's election, there shall be paid to the Holder at the time
Warrants are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of a share of Common Stock (as determined
in good faith by the Board of Directors of the Company).

     (c)  The Holder, by the acceptance of the Warrant, expressly waives his
right to receive any fractional Warrant or any fractional share upon exercise
of a Warrant.

     12.  RIGHT OF ACTION.  All rights of action in respect of this Warrant
Certificate are vested in the Holder.

     13.  AGREEMENT OF WARRANT CERTIFICATE HOLDERS. The Holder of this Warrant
Certificate by accepting the same consents and agrees with the Company and with
every other holder of a Warrant Certificate that:

     (a)  the Warrant Certificates are transferable only on the registry books
of the Company if surrendered at the principal office of the Company; and

     (b) the Company may deem and treat the person in whose name each Warrant
Certificate is registered as the absolute owner thereof and of the Warrants
evidenced thereby (notwithstanding any notations of ownership or writing on the
Warrant Certificates made by anyone other than the Company) for all purposes
whatsoever, and the Company shall not be affected by any notice to the
