                              AGREEMENT

Kenneth:

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

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

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

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

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

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

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

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

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

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

                               Very truly yours,
