    THIS AGREEMENT AND PLAN OF MERGER (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

Sub be merged with and into Seller, with Seller being the surviving 
corporation (the "Merger").  Each of the foregoing Boards of Directors has 
approved this Agreement, and Parent, as the sole stockholder of Acquisition 
Sub, has likewise approved this Agreement, all in accordance with applicable 
corporate law.  

    D.     On or before the Closing (as hereinafter defined), the

(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 
assign any of such stockholder's right, title or interest in or to any of the 
capital stock of Seller (except pursuant to this Agreement) unless this

concerning the lack of an intention to resell securities of Parent, if any, 
acquired pursuant to the Merger.

setting forth certain terms and conditions of the Merger and the mode of 
carrying the same into effect, Parent, Acquisition Sub and Seller agree as

                                    -3-



the Pennsylvania Consolidated Statutes and the respective Articles of 
Incorporation and Bylaws of the Constituent Corporations, as soon as

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 
authorized to execute and deliver, in the name and on behalf of the 
Constituent Corporations, all such deeds, bills of sale, assignments and 
assurances and do, in the name and on behalf of the Constituent Corporations,

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-




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-



     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-





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-





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 
necessary to satisfy all the conditions of Closing set forth herein at the 
earliest possible time.

     D.  CONDUCT OF BUSINESS BY SELLER PENDING THE MERGER. Seller covenants 
and agrees that, prior to the Effective Date, unless Parent and Acquisition 
Sub shall otherwise agree in writing and except as contemplated by this 
Agreement:

         (1)  the business of Seller shall be conducted only in the ordinary 
and usual course and consistent with past practices, Seller shall not enter 
into any agreement or transaction other than in the ordinary and usual course 
of business, and Seller shall not purchase, lease or sell (or enter into any 
agreement to purchase, lease or sell) any material properties, service or 
cryogen contracts or other assets other than in the ordinary and usual course 
of business; PROVIDED, HOWEVER, that Seller shall not enter into any 
agreement or transaction for the acquisition (by purchase, lease, rental or 
otherwise) of a diagnostic imaging unit or equipment or for provision of 
equipment or services to a health-care provider client, whether or not such 
agreement or transaction is in the ordinary course of business. In 


                                    -10-





particular, but without limitation of the foregoing, Seller shall not (a) 
incur or assume any indebtedness for money borrowed, or (b) agree to any 
amendment, adjustment or modification of or to any Material Contract (as 
hereinafter defined). Parent and Acquisition Sub acknowledge that Seller is 
contemplating a transaction for a full-time unit at the Samaritan Medical 
Center in Watertown, New York; consistent with the terms of this clause (i), 
Seller agrees to obtain the consent of Parent and Acquisition Sub before 
entering into any agreements with respect to the acquisition of a unit or its 
provision to such customer for imaging services and the terms of such MRI 
services contracts. Parent and Acquisition Sub acknowledge that Seller will 
spend up to $30,000 (including costs incurred prior to the date hereof) on 
the renovation and refurbishing of the Seller's office space;

         (2)  Seller shall not (a) amend its Articles of Incorporation or

directly or indirectly, by redemption or otherwise, any shares of the capital 
stock or other securities of Seller, or (c) enter into or modify any 
contract, agreement, commitment or arrangement with respect to any of the 
foregoing;

         (4)  Seller shall use its best efforts to preserve intact the 
business organization of Seller and to preserve the goodwill of those having 
business relationships with it;

         (5)  Seller shall conduct its relations with employees, including 
termination and hiring practices, and their employee benefit plans only in 
the ordinary and usual course and consistent with the past practices and 
policies of Seller, and shall not increase or pay any employee salaries or 
compensation in any manner; in particular, but without 


                                    -11-





limitation of the foregoing, the salary of each of Mark J. Graham and Albert 
F. Calfo, II shall continue through the Closing at $122,000 per annum, with 
$8,000 per month of such salary for each accruing but not paid;

         (6)  Seller shall not assume, guarantee, endorse or otherwise become 
responsible for the obligations of any other individual, firm or corporation

any assumptions, guarantees, endorsements, loans advances or other 
obligations in the ordinary and usual course of its business, and which do 
not exceed $5,000 in the aggregate;

         (7)  Seller shall not make any investment of a capital nature either

         (8)  Seller shall not enter into an agreement or otherwise agree to 
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 
notice to Parent and Acquisition Sub of (a) any notice of, or other 
communication relating to, a default or event which, with notice or lapse of 
time or both, would become a default, received by Seller subsequent to the 
date of this Agreement and prior to the Effective Date, under any agreement, 
indenture or instrument material to the 


                                    -12-





financial condition, business, properties or results of operations of Seller, 
and (b) any notice or other communication from any third party alleging that

business or results of operations.

     G.  ACCESS TO BOOKS AND RECORDS. Seller shall afford Parent, Acquisition 
Sub and their attorneys, accountants and other agents and representatives 
(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 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 
and representatives of Seller; PROVIDED, HOWEVER, that the fees 


                                    -13-

of the other party to the proposed disclosure).

of the accrued and outstanding trade payable amounts owed by Seller to

           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-



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-



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-



    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-




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-



    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-



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-



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-



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 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 
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.  

                                   -23-



    Q.   LABOR CONTROVERSIES.  There are no material labor controversies 
pending or threatened between Seller and any of its employees and Seller does 
not know of any organizational efforts presently being made involving any of 
such employees. Seller's relations with its employees are generally good. 
Seller does not know of any executive or key employee of Seller who has any 
plans to terminate his or her employment with Seller.  

    R.   MANAGEMENT TRANSACTIONS.  Other than (a) the lease of Seller's 
offices at a monthly rate of $5,756 from a partnership in which stockholders 
of Seller have an interest and (b) the rental or lease of tractors from 
Trucking, and except as disclosed on Schedule 4.18 hereto, 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 (including, in the case of each of Mark J. 
Graham and Albert F. Calfo, II, accrued and unpaid gross salary in the amount 
of $95,000 through March 31, 1996, such amount increasing at the rate of 
$8,000 per month (prorated for partial months on a daily basis) thereafter) 
and other than notes payable to Mark J. Graham and Albert F. Calfo, II in the 
aggregate amount of $104,868 plus accrued interest of $21,364 through March 
31, 1996.  The foregoing accrued and unpaid salary shall be paid to each of 
Mr. Graham and Mr. Calfo at the Closing.  Schedule 4.18 hereto lists all 
affiliates and related entities of Seller, Mr. Graham and Mr. Calfo which own 
assets related to, or engage in activities related to, the diagnostic medical 
imaging business, in each case including the name of the entity and its type 
and jurisdiction of organization, the nature and amount of the interest 
therein of Seller and each of Mr. Graham and Mr. Calfo, and a brief 
description of each agreement or transaction currently in effect or in effect 
at any time during the last twelve months between such entity and Seller.  
Since December 31, 1995, Seller has not (i) declared, set aside or paid any 
dividend or other distribution or payment in cash, stock or property in 
respect of any of its 

                                   -24-



shares of capital stock, or (ii) paid any amounts to Mark J. Graham or Albert 
F. Calfo II as salary, bonus or other compensation except in accordance with 
Section 3.4(v) hereof.

    S.   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 Parent and Acquisition Sub harmless from 
and against damages or cost incurred by reason of any such assertions.

    T.   NO UNDISCLOSED LIABILITIES.  Except as set forth in Schedule 4.20, 
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.

    U.   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 Parent 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 the financial condition, results of 
operations or prospects of Seller.

                                   -25-



VI.

                    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

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-



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-



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

                               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.



     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-



          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-



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-


          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-




     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-



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-



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

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.



     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-



          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-



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-



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-



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-



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-




          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-



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.

          A.  SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  All

Effective Date (as defined in the Merger Agreement) shall survive the 
completion of the Merger.

          B.  NOTICES.  All notices and other communications hereunder shall 
be in writing and shall be deemed to have been  duly given if delivered by 
messenger, transmitted by telecopy, telex or telegram or mailed by registered

The date of any such notice shall be deemed the date hand delivered or 
transmitted by telecopy, telex or telegram (in each case provided written 
confirmation of sending is retained) or three (3) days after being mailed as 
provided above.  Any party may change its address for notice by sending a 
notice to that effect as herein provided to the other parties.

          C.  AMENDMENT; ENTIRE AGREEMENT; BENEFICIARIES.  This Agreement 
(including the documents and instruments referred to herein) (a) constitutes 
the entire agreement and supersedes all other prior agreements and 
understandings, both written and oral, among the parties with respect to the 
subject matter hereof and (b) is not intended to confer upon any other person 
any rights or remedies hereunder.  This Agreement may be amended or modified 
in whole or in part by an agreement in writing executed in the same manner as 
this Agreement after authorization to do so, as applicable, by the Boards of 
Directors of Parent and Acquisition Sub and Stockholder.

          D.  WAIVER.  Any agreement on the part of a party hereto and any

forth in an instrument in writing signed on behalf of the party making the 
agreement or providing the extension or waiver.  

          E.  HEADINGS.  The headings contained in this Agreement are for 
reference purposes only and shall not affect in any way the meaning or 
interpretation of this Agreement.  

          F.  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon 
and inure to the benefit of and be enforceable by the respective successors 
and permitted assigns of the parties hereto.  The rights of Parent and 
Acquisition Sub hereunder may be transferred in whole or in part to any 
direct or indirect wholly-owned subsidiary of Parent.  

                                   -10-



          G.  GOVERNING LAW.  This Agreement shall be governed by and 
construed in accordance with the laws of the State of California, without 
giving effect to the choice of law provisions thereof.

          H.  COUNTERPARTS.  This Agreement may be executed in two or more 
counterparts, each of which shall be an original, but all of which together 
shall constitute one and the same agreement.

          I.  ATTORNEYS' FEES.  Should Parent or Acquisition Sub (or, 
following 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 applicable, court costs, incurred in 
connection with such matter. 

     IN WITNESS WHEREOF the parties have executed this Agreement by their 
duly authorized officers as of the date first above written.
