ITEM 1. DESCRIPTION OF BUSINESS

The Company
Diagnostic  Health Services, Inc. ("DHS" or the "Company")  is  a
leading  outsource  provider of medical  services  to  hospitals,
physicians'  offices  and  other  healthcare  facilities  in  the
Midwest,  West  and South Central United States.   DHS  primarily
provides  radiology  and  cardiology  diagnostic   services   and
equipment,  as  well  as  departmental  management  services,  to
healthcare  facilities  on an in-house  and  shared  basis.   The
Company   also  provides  skilled  allied  healthcare  personnel,
including  radiology  technologists,  physical  and  occupational
therapists  and  other healthcare professionals, on  a  temporary
basis  to perform a variety of functions in  hospitals, long-term
care facilities, physicians' offices, clinics and home healthcare
settings.

The   Company  was  incorporated  in  Texas  in  1983   and   was
reincorporated in Delaware in 1992.  The Company is headquartered
in  Dallas,  Texas,  and provides services  in  Texas,  Oklahoma,
Illinois, Indiana, Louisiana, Mississippi, Missouri, Iowa,  Ohio,
Michigan,   Arkansas,  Georgia,  Alabama,  Virginia,   Tennessee,
Kansas,  New  Mexico,  Arizona, Nevada,  California  and  in  the
greater Mexico City area.

In  addition  to  significant internal growth,  the  Company  has
expanded its business through numerous acquisitions.  Information
regarding acquisitions in the past three fiscal years is included
in the footnotes to the audited financial statements appearing at
Item 7 below.


The  following  chart sets forth the corporate structure  of  the
Company and its subsidiaries at March 21, 1997:

Business Operations

Shared Services
- ---------------
The   Company  operates  a fleet of specially  equipped  vehicles
(vans   and  trucks)  to  transport  its  imaging  equipment   to
hospitals,   clinics,  long- term  care  facilities   and   other
healthcare  settings.   The services provided   via  the   shared
services  mechanism are predominantly diagnostic ultrasound,  for
which  the equipment is portable and service  is rendered  on  an
"as  needed" basis.  This  includes a large number of regular and
routed  schedules as well as "on call"  services to customers  in
response to emergent  demand.

At  year- end  1996,  the  Company provided  shared  services  to
approximately  311  hospitals  and approximately  566  additional
clients  across  the healthcare  spectrum, including  physicians'
offices,  sub acute and long-term  care facilities, managed  care
systems,  and government facilities.

In-House  Services  (also referred to as Fixed Site Services)
- -------------------------------------------------------------
In  addition  to  the  shared  services,   the  Company  provides 
diagnostic  services  within  hospitals  and  clinical  radiology 
or cardiology departments.  These  services include the provision 
of the  allied healthcare  professional  (technologist) who staff 
the  equipment  and  is  responsible  for  image acquisition; the 
provision  and  management  of  diagnostic   equipment  or  other
related instrumentation; the management and  processing  of  data  
for the procedures conducted within  the  respective  department;  
and in some instances  the  provision,  via   subcontracting,  of  
the  professional  component  (interpretation)  of the  data by a 
physician.

These   in-house  services  may  include  any  or  all   of   the
aforementioned  responsibilities.  The imaging  modalities  under
management   include,   but  are  not  limited   to,   diagnostic
ultrasound, computerized tomography,  MRI, nuclear medicine,  and
cardiac catherization services.

Generally,  the  Company  is  responsible  for  various   quality
assurance  programs  related  to the  services  it  provides  and
assumes documentation responsibility and management oversight  of
departmental  compliance  issues,   licenses,  accreditation  and
certification requirements.

 At December 31, 1996,  the Company provided in-house services at
96 hospitals  throughout its operational  markets.

Ancillary Services
- ------------------
During  1996,  the  Company  reorganized  its  former  "TempTech"
division  into an operating unit that included (i) the provision
of  contract occupational and physical therapists on  a  long  or
short  term basis to healthcare facilities throughout the  United
States;  (ii) the provision of therapists and nurses  in  a  home
healthcare setting in Mexico City and surrounding areas, and (iii)
the  provision  of cardiac monitoring services,  such  as  Holter
monitoring, pacemaker monitoring and  event recording to patients
in several of the Company's markets.

                                       4

Customers
Each  of  the Company's customers, irrespective of the method  by
which  they  are served, has an agreement or contract  specifying
the  terms of service, including the nature of services, pricing,
payment  and other material terms.  The Company's agreements  for
in-house services typically have durations of three to five years
and  specify equipment and personnel requirements, the scope  and
types  of  services  to be provided and the pricing  and  payment
structure.

In  1995  and 1996, no single customer of the Company accounted
for  more than 10% of the Company's total revenues and the  three
largest  customers of the Company accounted in the aggregate  for
approximately  9%  of  the  Company's  revenues   in   1995   and
approximately  6%  of the Company's revenues in  1996.   In  most
cases,  the  hospital  or  healthcare  facility  (which  is   the
Company's  customer)  is the responsible  payment  party.   Third
party  payors  accounted for approximately  7%  and  15%  of  the
Company's revenue in  1995 and 1996, respectively.  Although  the
Company  is  not  substantially reliant upon third-party  payment
mechanisms, many of the Company's customers are reliant on third-
party  payment and delays or difficulties in third-party payments
could adversely affect the receipt and timing of payments to  the
Company.

From 1991 to 1996, the Company's customer base increased from 323
(including  seven  in-house agreements)  to  approximately  1,200
(including  96 in-house agreements).  Customers in 1996  included
409 hospitals and 711 physicians' offices, clinics and healthcare
facilities in 12 states.

   In  1996,  the Company's revenues were attributable to  shared
services,  in-house   services and  ancillary  services,  in  the
following approximate proportions:

</TABLE>

Operating Structure
Through   the   implementation  of  a  deliberate   and   prudent
acquisition  strategy, the Company has established a  network  of
operational  facilities throughout the country.   These  division
offices,  located  in  Arlington, San  Antonio  and  Houston, TX,
Los Angeles and San Diego, CA,  Albuquerque, NM, Phoenix, AZ, Las 
Vegas and  Reno, NV, Tulsa  and  Oklahoma  City OK, St. Louis MO, 
Chicago IL,  Atlanta,  GA and Monroe LA,  serve  as an operations 
base for both clinical staff,  local  management  and  sales.  By  
keeping these  functions  local, the  Company  remains responsive 
to its customer base as  well  as  to opportunities for expansion 
and development within the  Company's markets.

The  Company  provides local personnel with a comprehensive range
of  support  services,  including  financial  and  administrative
services,  and  employs a system which carefully  monitors  local
operations  through  an extensive system of  controls,  including
regular  financial  reporting, accounts receivable  analysis  and
customer   tracking.    The   Company   provides   administrative
functions   at   the   corporate  level,  including   receivables
management,   purchasing,   human   resources   and    accounting
thereby eliminating the need for these services locally.

                                       5

Management Information Systems
The  Company has configured an information technology system that
provides  real-time monitoring of services, procedures and  other
business  activities  at all of the Company's divisional offices.
This  enables the Company to monitor services, revenues and costs
on  a  Company-wide  basis.   The Company  has  made  substantial
investments  in  the development of this system and  all  of  the
Company's  business  offices are networked into  the  information
technology  system and integrated with the Company's  centralized
processing system.  This system also contributes to the Company's
sales  and  marketing  efforts by enabling  the  sales  force  to
formulate realistic quotations and pricing proposals to potential
customers and to provide management with information specific  to
existing  customers.  The Company believes that  its  information
technology   system  can  support  substantial   growth   without
requiring significant capital expenditures.

Sales and Marketing
The  Company directs its sales and marketing activities from  its
Dallas  headquarters, and out of each of its operating divisions.
Each  operating division has at least one, and in some  instances
more  than  one,  sales  representative  devoted  full  time   to
promotion of the Company's business and maintenance and expansion
of  existing relationships.  Additionally, each division  manager
as  well as the regional vice presidents devote portions of their
time to customer relations and marketing functions.

Competition
Radiology  and  cardiology diagnostic services, as  well  as  the
provision  of  allied healthcare professionals, are characterized
by  a high degree of competition.  This competition comes from  a
number of independent local operators specializing in one or  two
clinical   applications,  and  from  a  few   large   diversified
healthcare  companies  (primarily  larger  hospitals  having  the
resources and capability to provide shared diagnostic services to
other healthcare facilities) which provide these services as part
of their overall business.  Although the Company believes that it
has  a  competitive  advantage over most of the  small  operators
(primarily because most of them do not provide the full range  of
services offered by the Company, and do not have the same  volume
of  revenues  to  absorb  necessary fixed  overhead  costs),  the
Company  may  be  vulnerable  to  competition  from  the   larger
healthcare companies, at least one of which can be found in  each
of  the  Company's  geographic markets,  and  all  of  which  are
substantially larger and possess greater financial resources than
the company.  There can be no assurance that the Company will  be
able to compete successfully in its markets.

Seasonality
The  Company's results of operations have, in some years,  varied
significantly from quarter to quarter, for reasons particular  to
each  quarter.   For  instance, hospital  admissions  and  doctor
visits  (and,  therefore,  the Company's  imaging  revenues)  are
typically  lower during holiday periods, and at other times  when
physicians  traditionally take their own vacations.   Conversely,
revenues  from  the  Company's Ancillary Services  Division  have
generally  increased in holiday periods, due to increased  demand
for temporary personnel when regular staff is away.

Suppliers
Although  the  Company  has historically  acquired  most  of  its
imaging  and  other equipment through finance leases from  Acuson
Corporation and a small number of other suppliers, the Company is
not dependent upon any one supplier or group of suppliers.  While
the   Company  has  a  preference  for  the  for  the   equipment
manufactured  by  certain manufacturers, there are  a  number  of
manufacturers  of  imaging equipment adequate for  the  Company's
purposes, and an even greater number of companies from whom  such
equipment  can  be leased.  The Company believes  that  alternate
sources  for its equipment and supply needs are readily available
at   comparable  costs,  and  that  its  relationships  with  its
suppliers are satisfactory.

Patents or Trademarks
Although   the  Company  relies  upon  sophisticated   equipment,
instrumentation and technology, the Company does not own, license
or  otherwise  rely  upon  any  patents  or  trademarks  for  the
operation  of its business.  Other than corporate names  and  the
"TempTech Services" tradename for the Company's allied healthcare
services  business,  the  Company does not  own  or  utilize  any
trademarks in its business.

Government Regulation
Many aspects of the healthcare industry in the United States  are
presently  subject  to  extensive  federal and  state  government
regulation.  Certain of these laws and regulations are applicable
to  the Company's business.  The Company is also subject to  laws
and  regulations  relating to business corporations  in  general.
The   Company  believes  that  its  operations  are  in  material
compliance with all applicable laws.

Federal Law
Federal law prohibits the offer, solicitation, payment or receipt
of any remuneration (direct or indirect, overt or covert, in cash
or in kind) which is intended to induce, or is in return for, the
referral  of patients for, or the ordering of, items or  services
reimbursable  by  Medicare or Medicaid.  The law  also  prohibits
remuneration  intended to induce the purchasing of, or  arranging
for,  or  recommending the purchase or order of any  item,  good,
facility or service for which payment may be in whole or in  part
under those programs.  Under this statute, known as the "kickback
law,"  an offense may be punished by criminal prosecution  or  by
excluding  any  of the parties to the transaction or  arrangement
from  participation in Medicare and Medicaid.  The  law  is  very
broad  and  has been interpreted to apply to otherwise legitimate
investment  interests  if  one  purpose  of  the  offer   of   an
opportunity to invest is to induce referrals from the  investors.
Regulations  implemented under the kickback law  provide  certain
"safe  harbors"  giving  protection  for  certain  categories  of
relationships.

Federal   law   also  prohibits  physicians  from   ordering   or
prescribing  certain designated healthcare services or  items  if
the  service or item is reimbursable by Medicare or Medicaid  and
is provided by an entity with which the physician has a financial
relationship  (including  investment interests  and  compensation
arrangements).  Because of the breadth of this law, known as  the
"Stark  Law," a number of exceptions are included in the statute.
In  addition,  the Stark Law does not restrict a  physician  from
ordering  an  item  or service not reimbursable  by  Medicare  or
Medicaid.   Further,

                                       7
<PAGE>
 
payment for a service  provided in violation of the Stark Law may
be denied or money paid may be recouped.

Many  of  the services that the Company performs are reimbursable
by  Medicare or Medicaid and are included in the Stark Law's list
of designed healthcare services.  Therefore, the Company believes
that   the   Stark  law  applies  to  certain  of  its   business
relationships,  as does the federal kickback  law.   The  Company
believes that it is in  compliance with these laws.

Kickback Law
The  breadth  of  the  kickback law is such  that  virtually  any
financial  relationship between a practitioner and  a  healthcare
provider,   such  as  an  independent  physiological  laboratory,
involving  the  offering of Medicare and  Medicaid  services  may
trigger  the  application  of  the  law.   For  example,  if  the
opportunity  for a physician to provide interpretations  pursuant
to a personal services agreement with the Company was conditioned
upon  agreement  that  the  physician would  refer  his  Medicare
patients  for  diagnostic services to the Company,  the  personal
services  agreement could be construed as an inducement  for  the
physician's referrals.  However, the Company does not enter  into
any  professional services agreements for interpretation services
with  physicians who refer to the Company for diagnostic testing.
Further,  when  physicians contract with the Company  to  provide
diagnostic  testing, excluding any interpretation  services,  the
Company often bills for the technical component itself.  In  that
case,  nothing  of  value  is  exchanged  between  the  referring
physician  and the Company and the kickback law does  not  apply.
In  the  alternative, when the referring physicians purchase  the
diagnostic  service from the Company, the Company does  not  bill
the  Medicare  or Medicaid programs for the technical  component.
In  these  cases,  the physicians are required  to  disclose  the
amount charged by the Company for the technical component and the
physicians  are  reimbursed the amount charged  or  the  Medicare
RBRVS (resource-based relative value scale) amount, whichever  is
less.   The  Company believes that there is little, if any,  risk
that   its   purchased  diagnostic  testing   arrangements   with
physicians violate the federal kickback law.

A  substantial  portion  of the Company's  business  arrangements
involve  the  management  and  staffing  of  in-house  diagnostic
laboratories at hospitals.  The Company does not lease space from
the hospitals with which it contracts and does not bill any third-
party payors (including Medicare or Medicaid) or individuals  for
the  technical  services provided at the hospitals' laboratories.
Therefore,  the  Company believes that the federal  kickback  law
does not apply to its contractual arrangements with hospitals  to
operate diagnostic laboratories.

Stark Law
The  Stark  Law prohibits physicians from referring  Medicare  or
Medicaid  patients to entities with which they have  a  financial
relationship  for the provision of certain designated  healthcare
services.   The  services  specified by  the  Stark  Law  include
ultrasound  procedures which are provided by the Company  as  the
result  of referrals from physicians who purchase the tests  from
the  Company.   This relationship between the physician  and  the
Company  constitutes a compensation relationship under the  Stark
Law.   However, the Company believes that its relationships  with
referring  physicians qualify for the Stark Law's  exception  for
compensation  relationships  which  involve  payments   made   by
physicians for items or services at prices consistent  with  fair
market value.

                                       8
<PAGE>
 
State Law
A  number  of states, including states in which the Company  does
business,  have  laws  and regulations  similar  to  the  federal
kickback laws and Stark Law.  The Company believes that it is  in
compliance with all of such laws, although, as is the  case  with
federal law, there can be no assurance that changes in such  laws
or  the interpretation or enforcement of such laws  will not have
a material effect on the Company

The  Company  also operates in states that regulate  and  license
independent  physiological laboratories (IPLs).   In  all  states
that currently have such licensing requirements, the Company  has
received  such  licensure.  Further, for the last several  years,
the Health Care Financing Administration (HCFA) has considered  a
federal  requirement  that  all IPLs that  provide  services   to
individuals  covered under the Medicare or Medicaid  programs  be
required  to obtain certification by HCFA.  Currently,  HCFA  has
not  initiated  the  formal rulemaking process  for  federal  IPL
certification and the Company does not anticipate that HCFA  will
require  federal  certification  of  IPLs  in  the  near  future.
However,   in   the   event  that  HCFA  will   require   federal
certification  of IPLs in order to provide services  to  Medicare
beneficiaries of Medicaid recipients, the Company expects that it
will  meet  the  requirements  to obtain  federal  certification.
However,  the  Company cannot guarantee with  absolute  certainty
that  its  IPLs  will meet any future federal  IPL  certification
requirements.  Failure to obtain federal certification could have
a severe adverse impact on the operations of the Company.

Potential National Healthcare Reform
Both   the   Clinton   Administration  and  the   Congress   have
periodically  asserted a need to overhaul or reform the  nation's
healthcare  system.  Such  legislative initiatives,  if  enacted,
could  impose  pressures on the pricing structures applicable  to
the  Company's  services. In particular, there is  a  possibility
that  a  significant  portion  of  healthcare  services  will  be
rendered  and administered through "managed care" systems,  which
could  have  the  effect  of  forcing  pricing  concessions   and
reductions on the part of service providers such as the  Company.
Moreover, healthcare reform could also entail a greater  analysis
of  each patient's need for diagnostic testing, with the  aim  of
reducing  the  total volume of testing and the  overall  cost  of
medical  care. The Company is unable to predict whether, when  or
to  what  extent any new laws or regulations may be  enacted,  or
existing laws or regulations may be modified, any of which  could
have  a  material  adverse  effect  on  the  Company's  revenues,
operating margins and profitability.

Environmental Matters
With  the exception of the nuclear imaging services performed  by
the   Company,  the  Company's  operations  do  not  entail   the
handling,  storage, use, transport or disposal of  any  hazardous
substances  or  hazardous materials within  the  meaning  of  any
environmental  laws.  The Company is not aware  of  any  asbestos
abatement   activity  required  with  respect  to  any   of   its
facilities,  or  any  underground storage tanks  on  any  of  the
properties on which the Company's facilities are located.

The  Company's nuclear imaging services require the handling  of
radioactive  materials,  either  in  the  form  of  FDA-approved
single-dose  prepackaged  isotopes,  or  small  lots   of   bulk
materials  which  the  Company mixes  with  other  materials  to
expand  the  half-life  of the isotopes. These  nuclear  imaging
operations  are  conducted in the States of  Illinois,  Indiana,
Michigan  and  Louisiana.  The  State  of  Illinois  requires  a
separate  permit for the handling of these radioactive materials
and  Indiana,  Michigan and

                                       9
<PAGE>
 
Louisiana  are  so  called  "agreement states"  which  recognize
compliance with applicable  guidelines of  the  federal  Nuclear
Regulatory   Commission.  The  Company  believes  that  it holds
all necessary permits required by  state and   federal  law  and
that  it  is  in   compliance  with   all applicable  laws   and 
regulations relating to  the handling, storage,  use,  transport
and disposal  of  nuclear materials. Based  on advice  from  its 
insurance  carriers,  the  Company believes  that  this  limited
handling of radioactive  materials does not  warrant any special
insurance.

The  Company  has  not  experienced any environmental  regulatory
problems  in  the  past and has not been subject  to  any  fines,
penalties  or other liabilities under any environmental  laws  or
regulations.  However,  no assurance can  be  given  that  future
changes  in such laws or regulations, or interpretations thereof,
or  in  the nature of the Company's operations, will not  have  a
material impact on the Company.

Employees
As of  March 21, 1997, the Company had 367 full-time employees,
41 part-time employees, and 81 contract employees for a total of
489 employees  (including  operations in Mexico).  None of the

ITEM 2.  DESCRIPTION OF PROPERTY

Property
The  Company  maintains its headquarters in  approximately  8,781
square  feet  of  leased office  space  in Dallas,  Texas.   Base
rental at that facility is $12 per square foot per year, and  the
lease  expires  in  January  1999.  The  Company  also  maintains
divisional offices at 15 leased locations, ranging in  size  from
approximately  1,200 square feet to approximately  11,300  square
feet,  at  rentals generally ranging  from $4 to $15  per  square
foot  per  year (although rental at the Company's newly  acquired
Los  Angeles  office  is approximately $32 per  square  foot  per
year).   The  Company  believes that its existing  premises  will
provide   the  Company  with  adequate  space  for  its   current
operations for the foreseeable future.

Investment Policies
The  Company  generally acquires its assets for  the  purpose  of
producing  income  from the use of such assets in  the  Company's
operations.  The Company invests excess cash on hand primarily in
short-term  certificates of deposit and  United  States  Treasury
instruments.

The Company does not have any real estate-related investments and
does  not intend to make or acquire any such investments  in  the
foreseeable future.

ITEM 3.  LEGAL PROCEEDINGS

The Company is a party to litigation arising in the normal course
of  its  business.  No pending litigation involving  the  Company
(taken singly or in the aggregate) is expected to have a material
adverse  effect  on  the  Company or its  consolidated  financial
position.   The  Company is not aware of any  contemplated  legal
proceedings that may be brought against the Company in the future
and which would, if adversely determined, have a material adverse
effect on the Company or its consolidated financial position.

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

No  matters were submitted to a vote of security holders  in  the
fourth quarter of 1996.

In   prior  years,  the  Company  held  its  annual  meeting   of
stockholders  in late November.  However, in 1996, the  Board  of
Directors  determined to amend the Company's  by-laws  so  as  to
provide for the annual meeting of stockholders to be held  during
the  last  week  of  May  in  each year,  to  coincide  with  the
publication  of  the  Company's annual financial  statements  and
annual   report.   As  a  result,  the  term  of  each   existing
directorship  of  the Company was extended by  approximately  six
months, to coincide with such rescheduled annual meeting.

</TABLE>

On  March  21, 1997, the last reported sale price for the  Common
Stock was $8.625,  and the Company had 163 stockholders of record
as  of that date.  The Company believes that there are more  than
1,200 beneficial owners of Common Stock.

Recent Sales of Unregistered Securities
In the past three years, in addition to options granted under the
Company's  various  stock option plans (see Item  10  below)  and
securities  issued  in  connection with  the  Company's  business
acquisitions  (see the notes to the audited financial  statements
included  in  Item  7 below), the Company consummated  a  private
placement  in April 1996 of unregistered promissory notes  in  an
aggregate  amount  of  $1,000,000 (the "Bridge  Notes"),  and  in
connection  therewith, issued , to the purchasers of such  Bridge
Notes,  warrants  (the "Bridge Warrants") entitling  the  holders
thereof to purchase, at any time through April 15, 2001, up to an
aggregate of 50,000 shares of common stock of the Company  at  an
exercise price of $6.25 per share, subject to adjustment

                                       12
<PAGE>
 
upon  the  occurrence  of  any  stock dividends,  stock  splits,
combinations  of shares or reclassifications of the Common Stock,
or upon  any consolidation or merger of the Company with or into
another corporation. Commencing October 15, 1997, the Company has
the right to call the Bridge Warrants for redemption at $.01 per
Bridge Warrant on 30 days' written notice if the average market
price of the Common Stock equals or exceed $9.00 per share
(subject to adjustments in respect of the aforedescribed events)
for any 20 trading days within a period of 30 consecutive trading
days ending on the fifth trading day prior to the date of the
notice of redemption. As of the date of this report, an aggregate
of 35,000 Bridge Warrants have been exercised, although
certificates for only 2,500 of such shares have been issued. The
issuance of the Bridge Notes and the Bridge Warrants was exempt
from registration under Regulation D promulgated under the
Securities Act of 1933, as amended (the "Act"), based upon
representations and warranties made by the eighteen purchasers
thereof as to their status as "accredited investors."

Simultaneously  with  the issuance of the Bridge  Notes  and  the
Bridge  Warrants,  the Company borrowed an additional  $1,000,000
from  Texas Commerce Bank National Association  (TCB"),  in
conjunction with which the Company issued to TCB warrants  ("Bank
Warrants") entitling the holders thereof to purchase up to 50,000
shares   of   Common  Stock.   The  exercise  price,   adjustment
provisions, call provisions and other terms and conditions of the
Bank  Warrants are identical to the terms and conditions of   the
Bridge  Warrants.  The issuance of The Bank Warrants  was  exempt
from registration pursuant to Regulation D promulgated under  the
Act  based  upon TCB's representations and warranties as  to  its
status as an "accredited investor."

In connection with the Company's acquisition of Advanced Clinical
Technology,  Inc.  and  Horizon  MDS  Corporation  (collectively,
"ACT")  in  November 1996 (see Note 11 to the  audited  financial
statements included in Item 7 below), the Company issued  to  ACT
642,857 shares of Series A Convertible Redeemable Preferred Stock
of the Company ("Series A Preferred Stock"), having  an aggregate
liquidation  preference of $4,500,000.  The shares  of  Series  A
Preferred  Stock  bear dividends at the rate of 7.25%  per  annum
(payable  in  kind  in additional shares of  Series  A  Preferred
Stock),  and  all outstanding shares of Series A Preferred  Stock
(including accrued dividends) are convertible, at the  option  of
the holder thereof,  into Common Stock of the Company at the rate
of one share of Series A Preferred Stock for each share of Common
Stock.   In  addition,  in the event that,  commencing  with  the
Company's  fiscal  quarter ending December  31,  1997,  the  mean
average  daily last reported sale price of the Common Stock  (the
"Average  Closing Price") in any fiscal quarter  of  the  Company
shall  be  less than $7.00 per share, then, at any time and  from
time  to  time during the next succeeding fiscal quarter  of  the
Company, each outstanding share of Series A Preferred Stock  will
be  convertible into a number of shares of Common Stock equal  to
$7.00  divided by the Average Closing Price during the  preceding
fiscal  quarter.   The Company has reserved the  right  to  limit
ACT's  holdings  of  conversion  shares  to  4.9%  of  the  total
outstanding   common  stock (or 9.9% in the event  of  and  after
giving  effect to any conversion at the reduced price  under  the
immediately  preceding sentence).  The issuance of the  Series  A
Preferred   Stock  was  exempt  from  registration  pursuant   to
Regulation D and  promulgated under the Act, and based  on  ACT's
warranty as to the acquisition of such shares for investment  and
not for resale or distribution.

Dividend Policy
The  Company has not previously paid any dividends on its  common
stock  and  for  the foreseeable future intends to  continue  its
policy  of retaining any earnings to finance the development  and
expansion  of  its  business.  In addition,  the  Company's  loan
agreement  with Texas Commerce Bank National Association  ("TCB")
prohibits  the payment of dividends without TCB's prior  consent.
In  the  future, the payment of dividends by the Company  on  its
Common   Stock  will  also  depend  on  the  Company's  financial
condition,  results of operations and such other factors  as  the
Board of Directors of the Company may consider relevant.

NOTE:  Numbers may not add due to rounding.

Year  Ended  December 31, 1996 Compared With Year Ended  December
31, 1995

Gross revenues increased by 41.5% to approximately $24,171,000 in
1996  from approximately $17,083,00 in 1995.  Excluding  revenues
attributable to acquired businesses, gross revenues increased  by
25.5%  to  approximately $18,791,000 for 1996 from  approximately
$14,966,000 for 1995.

The  Company's  operating expenses increased  from  approximately
$15,336,000 in 1995 to approximately $20,268,000 in 1996.   As  a
percentage of net sales, operating expenses decreased from  89.9%
to  83.9%.   The  decrease  was  due  to  increased  efficiencies
realized   through   consolidation  of   various   overhead   and
administrative functions, and absorption of fixed costs  over  an
increased revenue base.

Income  from  operations  increased by  123.4%  to  approximately
$3,903,540 in 1996 from approximately $ 1,747,035  in 1995.  As a
percentage  of  gross revenues, income from operations  increased
from 10.2% in 1995 to 16.2% in 1996.

Interest  expense increased by 96.8% from approximately  $442,000
in  1995 to approximately $870,000 in 1996, primarily as a result
of   new   obligations  acquired  in  connection  with  the   ACT

                                       15
<PAGE>
 
acquisition.   As  a  percentage of net sales,  interest  expense
increased from 2.5% in 1995 to 3.6% in 1996.

"Other   income"   is  primarily  interest   earned   on   liquid
investments.

Net  income  approximately doubled from  $1,227,000  in  1995  to
$2,459,000 in 1996.  This increase is primarily due to  continued
consolidation  of  the  Company's administrative  functions,  and
increased   sales.   As  a  percentage  of  sales,  all   expense
categories  were  down  in  1996,  except  for  depreciation  and
amortization.

Liquidity and Capital Resources
In  July 1996, the Company and its subsidiaries entered in to  an
amended  and  restated  revolving credit and term  loan  facility
with  TCB,  providing for up to $2,500,000 in available revolving
credit  (or,  if less, 75% of the Company's and its subsidiaries'
eligible  accounts  receivable  from  time  to  time),   and   an
acquisition  term loan facility of up to $17,500,000 in  original
principal   amount.    At  December  31,  1996,   the   Company's
outstanding  borrowings under the loan agreement were  $1,572,000
under  the  revolving credit facility, and $8,569,573  under  the
term  loan facility.  These loans bear interest at varying rates,
depending on the Company's relative leverage from time  to  time.
The  Company and its subsidiaries have also entered into  various
financing  arrangements  with commercial  leasing  companies  and
equipment suppliers, bearing interest ranging from 6% to 11%  per
annum.

In  July  1996, the Company also completed a public  offering  of
Common Stock, pursuant to which the Company realized net proceeds
of approximately $17,504,500.  The proceeds of this offering have
been  and  continue to be utilized to retire debt (including  the
Bridge  Notes)  and  lease financing liabilities,  to  consummate
acquisitions, and for working capital.

At December 31, 1996, the Company had approximately $5,220,000 in
cash, cash equivalents and  short-term investments and additional
unused  availability  of  $928,000  under  its  revolving  credit
facility.   From  February  1  to March  20,  1997,  the  Company
received  approximately  $4,379,000  from  the  exercise  of  its
publicly  traded  warrants and certain of  the  Bridge  Warrants.
Based  on the Company's operating plan, management believes  that
available resources and funds generated from operations  will  be
sufficient  to meet the Company's operating requirements  through
the close of the Company's fiscal  year ending December 31, 1997.

The Company has retained Prudential Securities, Inc. to effect  a
private   placement   of  $20,000,000  of   senior   subordinated
promissory  notes, in connection with (a) the Company's  proposed
acquisition  of  four  magnetic  resonance  imaging  centers   in
California  from Diagnostic Imaging Services, Inc.  ("DIS"),  and
(b) to retire a $5,500,000 advance made to the Company by TCB  in
connection  with  the  Company's acquisition  of  the  ultrasound
division of DIS consummated in March 1997.

Trends and Uncertainties
The  Company's future revenues and results of operations  may  be
substantially  affected  by  proposed  reforms  of  the  nation's
healthcare  system and by potential reductions  in  reimbursement
rates  and  policies  imposed by Medicare and  other  third-party
reimbursement programs (from which the Company derives a material
portion  of  its  receipts).   Continuing  pressures  on  pricing
structures  applicable to the Company's services could  have  the
effect  of  reducing the Company's revenues and operating  profit
margins.   The Company is unable to predict the nature or  extent
of  any  such  policy changes and/or the effects thereof  on  the
Company.

                Independent Auditors' Report



The Board of Directors
Diagnostic Health Services, Inc.

We  have audited the accompanying consolidated balance sheets  of
Diagnostic Health Services, Inc. and Subsidiaries as of  December
31,  1996  and  1995, and the related consolidated statements  of
operations,  stockholders' equity and cash flows  for  the  years
then  ended.   These  consolidated financial statements  are  the
responsibility  of the Company's management.  Our  responsibility
is   to  express  an  opinion  on  these  consolidated  financial
statements based on our audits.

We  conducted  our  audit in accordance with  generally  accepted
auditing  standards.  These standards require that  we  plan  and
perform  the  audit to obtain reasonable assurance about  whether
the  consolidated  financial  statements  are  free  of  material
misstatement.   An  audit includes examining, on  a  test  basis,
evidence   supporting  the  amounts  and   disclosures   in   the
consolidated  financial  statements.   An  audit  also   includes
assessing   the   accounting  principles  used  and   significant
estimates  made by management, as well as evaluating the  overall
consolidated  financial statement presentation.  We believe  that
our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to
above  present  fairly, in all material respects,  the  financial
position of Diagnostic Health Services, Inc. and Subsidiaries  at
December  31, 1996 and 1995, and the results of their  operations
and  cash  flows  for  the years then ended  in  conformity  with
generally accepted accounting principles.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- ---------------------------------------------------

Revenue  Recognition -- Revenues are recognized when  services  are
performed  and are recorded at published charges, net of  discounts
and  contractual allowances.  Revenues received under the  Medicare
program are subject to audit and possible adjustment by third party
reimbursement agencies.

Prepaid  Expenses  -- Prepaid expenses represent  advance  payments
made  or  liabilities incurred on various contracts and  agreements
with  initial  terms of one year or less.  The carrying  amount  of
prepaid expenses is determined by comparing the remaining period of
the agreement to its initial cost.

Property and Equipment -- Property and equipment are stated at cost
and  are  depreciated  using  the  straight-line  method  over  the
estimated  useful lives of the related assets or terms  of  leases,
ranging from 3 to 7 years, whichever is less.

Contracts  Receivable  --  Contracts receivable  represents  future
payments   due  on  long-term  equipment  and  service  agreements.
Expected  profits or losses on contracts are based on the Company's
estimates   of  total  revenue  values  and  related   costs   upon
installation.    These   estimates   are   reviewed   and   revised
periodically throughout the lives of the contracts, and adjustments
resulting from such revisions are recorded in the periods in  which
the  revisions are made.  Losses on contracts will be  recorded  in
full as they are identified.

Goodwill  --  The excess of the aggregate purchase price  over  the
fair  market value of net assets of businesses acquired is included
in  the  accompanying balance sheet as goodwill, and  is  amortized
over  a  twenty-year  period using the straight-line  method.   The
Company  periodically evaluates whether changes have occurred  that
would  require revision of the remaining estimated useful  life  of
the  assigned goodwill or impair the recoverability of the carrying
value  of  the goodwill.  If such circumstances arise, the  Company
records  an impairment loss as the difference between the  estimate
of  the  related  after-tax income contribution,  on  a  discounted
basis, and the carrying value of the goodwill.  Any impairment loss
would  be  reported  as  a  component  of  income  from  continuing
operations before tax.

Noncompete  Agreements -- Noncompete agreements are amortized  over
the life of the agreements, which range from two to five years.

Cash  Equivalents -- For purposes of the statement of  cash  flows,
the  Company  considers  any  short-term  cash  investment  with  a
maturity of three months or less to be a cash equivalent.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)
- ---------------------------------------------------------------

Long-Lived  Assets -- In accordance with SFAS No. 121,  "Accounting
for  the Impairment of Long-Lived Assets and for Long-Lived  Assets
to  be  Disposed  of" ("SFAS 121"), the Company records  impairment
loses  on  long-lived assets used in operations, including goodwill
and  intangible assets, when events and circumstances indicate that
the  assets  might  be  impaired and the  undiscounted  cash  flows
estimated  to  be  generated by those  assets  are  less  than  the
carrying amounts of those assets.  The adoption of SFAS 121 has had
no  material impact on the Company's financial condition or results
of operations.

Income Taxes -- The Company accounts for income taxes in accordance
with   Statement  of  Financial  Accounting  Standards   No.   109,
"Accounting  for  Income  Taxes," which requires  the  use  of  the
"liability  method" of accounting for income taxes. Deferred  taxes
are provided using the liability method whereby deferred tax assets
are  recognized for deductible temporary differences  and  deferred
tax  liabilities are recognized for taxable temporary  differences.
Temporary  differences  are the differences  between  the  reported
amounts  of  assets and liabilities and their tax bases.   Deferred
tax  assets and liabilities are adjusted for the effects of changes
in  tax laws and rates on the date of enactment.  The Company files
consolidated income tax returns.

Earnings  Per  Share  -- Earnings per share has  been  computed  by
dividing  net income  by the weighted average number of shares plus  
common stock equivalents outstanding during the period. The primary
weighted  average  common shares and common  share  equivalents  at
December   31,   1996  and  1995  were  7,740,622  and   5,408,643,
respectively.

Use of Estimates and Assumptions -- Management  uses  estimates and 
assumptions in preparing its financial statements.  Those estimates 
and   assumptions  affect   the  reported  amounts  of  assets  and 
liabilities, the  disclosure of  contingent assets and liabilities, 
and the reported amounts of revenues and expenses.   Actual results 
may vary from the estimates that were used.

New Accounting Standards -- In October 1995, Statement of Financial 
Accounting   Standards   No.   123,   "Accounting  for  Stock-based 
Compensation" ("SFAS 123"), was issued. This statement requires the 
fair  value  of  stock  options  and other stock-based compensation 
issued to employees, to  either be included as compensation expense 
in  the  income statement or the pro forma effect on net income and 
earnings  per share of such compensation expense to be disclosed in 
the  footnotes  to  the Company's financial statements,  commencing 
with the Company's 1996  fiscal  year.   DHS  adopted SFAS  123  on 
January 1, 1996.  The Company will continue to measure compensation 
costs using  the  "intrinsic  value based method" of accounting for 
stock issued to employees.

NOTE 4 - NOTES PAYABLE (Continued)
- ----------------------------------

The  Company's  revolving credit and term note  agreements  contain
certain  restrictive  covenants  which,  among  other  things,  (1)
require the maintenance of a minimum current ratio, (2) provide for
a  maximum  funded  debt ratio (as defined in the loan  agreement),
(3)  require  the  maintenance of a minimum fixed  charge  coverage
ratio  (as  defined in the loan agreement), and (4)  place  certain
restrictions on the Company's ability to declare or pay  dividends,
make  certain loans, advances or investments, or incur,  create  or
assume additional debt or other obligations.

At December 31, 1995, the Company was not in compliance with one of
these  restrictive covenants, namely the requirement to maintain  a
minimum current ratio of 1.20 to 1.00. The Company's current  ratio
at December 31, 1995 was 1.12 to 1.00.  However, the bank granted a
waiver of such noncompliance as of December 31, 1995.

goodwill   of  approximately  $136,000  in  connection   with   the
acquisition.  Concurrent with the acquisition, the Company  entered
into a non-competition and non-disclosure agreement with the former
owner of Reliascan valued at approximately $80,000.

On  September 6, 1994, through a reverse triangular merger  between
MDI  Acquisition  Corp. (a wholly-owned subsidiary  of  DHSMS)  and
Mobile Diagnostic Imaging, Inc. ("Mobile"),  DHSMS acquired 100% of
the issued and outstanding capital stock of Mobile and, indirectly,
of  its wholly-owned subsidiary, St. Louis Mobile Ultrasound,  Inc.
(collectively, with Mobile, "MDI").  The business of  MDI  consists
primarily    of   performing   and   rendering   sonographic    and
neurodiagnostic testing services for various medical  applications,
primarily  on  a  mobile  basis  to hospitals,  clinics  and  other
healthcare  facilities  in  the  greater  St.  Louis,  Chicago  and
Indianapolis metropolitan areas.

The  Company  acquired  net  assets of  approximately  $497,000  in
exchange  for  488,889  shares of DHS common stock  and  three-year
warrants  (expiring September 6, 1997) for the purchase  of  75,000
additional shares of DHS common stock at an exercise price of $3.00
per  share.  Simultaneous with the closing of the acquisition,  the
Company entered into an employment agreement with James R. Angelica
(formerly  the  principal  stockholder  and  President  of  Mobile)
pursuant to which he has agreed to serve as Vice President-Sales of
the  Company through August 31, 1997, at a base salary  of  $85,000
per  annum  plus  customary benefits.  Also simultaneous  with  the
closing  of  the acquisition, Mobile entered into a non-competition
and  non-disclosure agreement with Mr. Angelica pursuant to  which,
among  other  things, Mr. Angelica has agreed not to  compete  with
Mobile  or the Company for a period of five years, in consideration
of  which Mobile has agreed to pay Mr. Angelica a total of  $90,000
in  equal  monthly  installments from September  30,  1994  through
August  31, 1997.  The Company recognized goodwill of approximately
$1,011,000 in connection with the acquisition.

NOTE 11 - ACQUISITIONS (Continued)
- ----------------------------------

Upon  closing of the acquisition, Mr. Angelica was elected  to  the
Board  of Directors of the Company for a term expiring on or  about
November 15, 1994.  Additionally, Mr. Angelica and his spouse  have
granted  to Max W. Batzer (the Chairman and Chief Executive Officer
of  the Company) a three-year proxy (expiring September 5, 1997) to
vote the 370,252 shares of common stock of the Company acquired  by
them  in  the  transaction.  Such proxy directs  that  the  subject
shares  be voted (a) with respect to election of directors  of  the
Company,  in  such  manner  as  Mr. Batzer  may  determine  in  his
discretion, and (b) as to all other matters, in the same manner  as
the   greatest   plurality  of  votes,  consents  or  ratifications
otherwise cast or given with respect to the particular matter.  Mr.
Batzer  voted such shares, as well as his own shares, in  favor  of
Mr.  Angelica's reelection as a Director at the 1994 annual meeting
of stockholders held on November 23, 1994.

On March 9, 1995, effective as of January 1, 1995, DHSMS (through a
new  wholly-owned subsidiary, HDI Acquisition Corp.)  acquired  the
businesses of three San Antonio, Texas-based companies which are in
similar  lines  of  business as the Company.  The  acquisitions  of
Sector-Echos   Inc.   ("SEI"),  Cardio-Graphic  Consultants,   Inc.
("CGCI")  and Heart Diagnostic Institutes, Inc. ("HDII") were  made
for  a  combination of $352,000 in cash and 84,211  shares  of  DHS
common  stock.   The Company acquired net assets  of  approximately
$659,000 including goodwill of approximately $399,000 in connection
with  the acquisitions.  The Company merged the acquired businesses
into another wholly-owned subsidiary of DHSMS in 1996.

On   July  31,  1995,  the  Company,  through  DHSMS'  wholly-owned
subsidiary SIS, purchased substantially all of the operating assets
(exclusive   of  cash  and  accounts  receivable)  of  the   mobile
ultrasound and nuclear imaging division of MICA Imaging, Inc.   The
purchase  included  approximately  $5,034,000  of  various   assets
including goodwill of approximately $2,528,000.  The purchase price
was  approximately $3,746,000 in cash, and SIS assumed  liabilities
of approximately $1,288,000.

Simultaneous with the closing of the acquisition, the  Company  and
its  subsidiaries entered into a loan agreement with Texas Commerce
Bank National Association, providing for an acquisition loan in the
principal amount of $3,750,000, a term loan in the principal amount
of  $1,000,000, and a revolving credit facility of up to $1,000,000
(or,  if  less, 75% of the Company's and its subsidiaries' eligible
accounts receivable from time to time).  In connection with the ADI
acquisition (see Note 12 below), the Company obtained an additional
$600,000  term  loan under the loan agreement.  All  of  the  loans
under  this loan agreement were refinanced with the same lender  in
June 1996, as described in Note 4 above.

NOTE 11 - ACQUISITIONS (Continued)
- ----------------------------------

In January 1996, Mobile Diagnostic Systems, Inc. ("MDS", a wholly-
owned subsidiary of DHSMS) acquired all of the outstanding
capital stock of two affiliated Dallas, Texas-based businesses,
Neonatal Pediatric Echocardiography, Inc. ("NPE") and Pediatric
Echocardiagraphic Diagnostic Imaging, Inc. ("PEDI"), in exchange
for an aggregate of 85,200 shares of DHS common stock.  The
Company acquired net assets of approximately $426,000 including
goodwill of approximately $248,000 in connection with the
acquisitions.  In December 1996, NPE was merged into MDS.

On June 28, 1996, MDS acquired all of the outstanding capital
stock of Cardiac Concepts, Inc.  ("CCI").  The purchase price
consisted of 22,785 shares of the Company's common stock, in
consideration of which the Company received net assets valued 
at approximately $150,000 including goodwill of approximately 
$657,000. On the date of the acquisition, the Company also 
issued 26,861 shares of common stock in payment of approximately 
$177,000 of the debt and liabilities of CCI.  The acquisition of 
CCI has been accounted for under the purchase method of accounting 
with the purchase price being allocated to assets and liabilities 
based upon their fair market value at the date of acquisition.  

Effective  October  31, 1996, MDS acquired by  merger  all  of  the
outstanding capital  stock of Dysrythmic Data, Inc. ("DDI), a Texas-
based    provider  of  ambulatory  electrocardiographic  monitoring
services.   The  consideration paid for  DDI  consisted  of  39,521
shares of common stock of the Company.

On  November 13, 1996,  DHSMS purchased substantially  all  of  the
operating  assets  (exclusive of cash and mobile x-ray  assets)  of
Advanced  Clinical  Technology, Inc.  and  Horizon/MDS  Corporation
(collectively "ACT"). The consideration paid for ACT  consisted  of
approximately  $12,620,000 in cash and $4,500,000 in  the  form  of
642,857  shares of Series A Convertible Redeemable Preferred  Stock
of  the  Company,  with  an  aggregate  liquidation  preference  of
$4,500,000.   The Company also assumed approximately $4,727,000  of
liabilities.

NOTE 12 - POOLING OF INTERESTS
- ------------------------------

On  December  7,  1995, the Company issued 240,000  shares  of  its
common stock in exchange for all of the outstanding common stock of
ADI.   The  transaction has been accounted  for  as  a  pooling  of
interests  and,  accordingly, the Company's consolidated  financial
statements   have  been  restated  to  include  the  accounts   and
operations  of  ADI  for  all  periods  presented  prior   to   the
consummation of the transaction.

ADI  was  a  Subchapter S corporation for income tax purposes  and,
therefore,  did not pay federal income taxes.  ADI is  included  in
the  Company's  federal  income tax return effective  November  30,
1995.   Deferred  income  taxes related  to  acquired  net  taxable
temporary differences were not material.

For  the eleven months ended November 30, 1995, ADI reported  gross
revenues  and  net income of $1,421,273 and $493,294, respectively.
Adjustments to the accounts of ADI to adopt accounting practices of
the  Company resulted in adjusted gross revenues of $1,391,902  and
adjusted  net  income of $463,923 for the year ended  December  31,
1995.  Substantially all of the required adjustments related to the
conversion  to the accrual basis of accounting.  During  1995,  ADI
distributed $350,000 to its sole shareholder.

NOTE 13 - RELATED PARTY TRANSACTIONS
- ------------------------------------

A stockholder of the Company is a principal in a firm that provides
financial  consulting services to the Company.  Fees  paid  to  the
firm in 1996 and 1995 were $63,740 and $51,432, respectively.

The  accounts  receivable from stockholders consist of  $13,543  of
other  advances made to three of the Company's stockholders  as  of
December  31, 1996 and 1995, and $26,910 and $20,700, respectively,
of accrued interest on the stockholder receivables.

NOTE 14 - STOCK OPTION PLANS
- ----------------------------

On  April  15,  1992, DHS adopted a stock option  plan  (the  "1992
Plan")  that  authorizes  the  granting  of  options  to  officers,
directors and selected key employees and/or consultants to  acquire
shares  of  DHS common stock.  The aggregate number of shares  with
respect  to which qualified incentive options may be granted  shall
not  exceed 180,702 shares, with the exercise price being not  less
than  the  fair  market value at the date of grant.  The  aggregate
number of shares with respect to which non-qualified options may be
granted  shall not exceed 722,807 shares.  The exercise  price  for
the  non-qualified options shall not be less than 85% of  the  fair
market  value  at  the  date of grant.  Substantially  all  of  the
available  options  under  the 1992 Plan  have  been  granted,  and
659,935  of  such awarded options contain optional price  reduction
provisions in connection with any change in control of the Company.

In  April 1995, in response to the substantial increase in the size
of  the Company and its labor force, the Board of Directors of  the
Company adopted and approved the Company's 1995 Non-Qualified Stock
Option  Plan  ( the "1995 Non-Qualified Plan"), pursuant  to  which
officers, directors, and/or key employees and/or consultants of the
Company can receive non-qualified stock options to purchase  up  to
an aggregate of 500,000 shares of  the Company's common stock.  The
exercise  price,  expiration date and other terms  of  any  options
granted under the 1995 Non-Qualified Plan are substantially similar
to  the requirements applicable to non-qualified options under  the
1992  Plan.   Through  December 31, 1995, the  Company's  Board  of
Directors had awarded, under the 1995 Non-qualified Plan, (a) stock
options  for  an aggregate of 133,000 shares, all of which  provide
for   an  exercise  price  of  $1.9375  per  share,  are  currently
exercisable  and  expire  on  April  4,  2003  (subject  to   prior
termination  in  accordance  with  the  application  stock   option
agreements),  and (b) additional stock options for an aggregate  of
36,000 shares, all of which provide for an exercise price of  $4.25
per  share, are currently exercisable and expire on August 20, 2003
(subject  to prior termination in accordance with applicable  stock
option   agreements).   98,000  of  such  awarded  options  contain
optional  price reduction provisions in connection with any  change
in control of the Company.

In  November  1995, the stockholders of DHS approved the  Company's
1995  Incentive  Stock Option Plan (the "1995 Incentive  Plan")  as
previously adopted by DHS' Board of Directors.  A total of  500,000
incentive  stock  options may be issued from time to  time  to  key
employees  of the Company under the 1995 Incentive Plan,  on  terms
and  conditions  (including an exercise price not  less  than  fair
market  value on the date of grant) satisfying the requirements  of
the  Internal Revenue Code with respect to incentive stock options.
Through  December 31, 1995, no options had been granted  under  the
1995 Incentive Plan.

Vesting  varies  by  agreement  ranging  from  zero th three years.      
Compensation  costs  will  be  recognized  as  an  expense over the       
periods  of  employment attributable to the options  at  an  amount
equal  to the excess of the fair market value of the stock  at  the
date  of  measurement over the amount the employee must  pay.   The
measurement  date is generally the grant date.  As of December  31,
1996 and 1995, no compensation cost was recognized as expense.  Had
compensation  cost for the Company's stock-based compensation  been
determined on the fair value at the grant dates for awards with the
method  of FASB Statement 123,  the Company's net income would have 
been $2,410,489  for the year ended December 31, 1996.  Accordingly, 
primary and fully-diluted earnings per share would have amounted to 
$0.31 per share and $0.30 per share respectively, as of December 31,

NOTE 15 - SUBSEQUENT EVENTS
- ---------------------------
     
In January 1997, the Company, through its Heart Institute of Tulsa,
Inc.  subsidiary,  acquired  Ultrasound Diagnostic  Services,  Ltd.
("UDS"),  an  Arizona-based  provider  of  non-invasive  diagnostic
ultrasound  testing  services.   The  consideration  paid  for  UDS
consisted  of  86,520 shares of DHS's common stock and  a  $400,000
cash payment to the former stockholders of UDS.

Effective  March 1, 1997, the Company, through its SoCal Diagnostic
Services,  Inc.  subsidiary, purchased  substantially  all  of  the
operating  assets of the ultrasound division of Diagnostic  Imaging
Services,   Inc.  ("DISI").   The  acquired  business  includes   a
mobile/fixed  ultrasound business serving  clients  in  San  Diego,
Orange  and  Los Angeles counties.  The acquisition  of  DISI  will
provide  DHS  with  a  firm foundation in the  southern  California
market,  which is contiguous with the Company's existing operations
in  Arizona  and Nevada, as well as departmental access to  leading
hospitals  in  this market.  Pursuant to long-term contracts,  DISI
provides  ultrasound services to 26 facilities and numerous  shared
service  accounts.   Simultaneous  with  such  acquisition,   DHSMS
received an option to purchase four hospital-based MRI centers from
the same seller.

On February 14, 1997, the SEC declared effective the Company's Form
S-3  Registration  Statement relating to an offering  of  1,791,150
Warrant  Shares, which are issuable upon exercise of (i)  1,375,000
Redeemable  Common Stock Purchase Warrants (the "Public  Warrants")
issued  in  connection  with  the  company's  1993  initial  public
offering  (the "IPO"), (ii) 316,150 underwriter warrants issued  in
connection with the IPO (the "Underwriters' Warrants"),  and  (iii)
100,000  warrants  issued in connection with DHS's  equity  private
placement in April 1996 (the "Bridge Warrants") of which 2,500  had
been exercised prior to the effectiveness of the registration.   On
February  18,  1997, the Company called all of the Public  Warrants
for redemption.

The Warrants are exercisable at prices ranging from $7.50 per share
to  $5.48  per  share.  On February 25, 1997, the last  sale  price
quoted on NASDAQ for a share of DHS's common stock was $9.375.  The
Company  will not receive any proceeds from the sale of the Warrant
Shares,  although  it has received, and will continue  to  receive,
proceeds  from the exercise of the Warrants, if and to  the  extent
exercised.   In the event that all of the unexercised Warrants  are
exercised, the maximum aggregate net proceeds to the Company  would
be  approximately  $11.2  million.  To the  extent  received,  such
proceeds   may  be  utilized  to  repay  a  portion   of   existing
indebtedness  for  working capital, for general corporate  purposes
and  for possible acquisitions (none of which have been identified)
at the discretion of the Company's management.

amount, as to each person, which is less than the lesser of $50,000
or 10% of the total salary and bonus for the subject year.

employment on September 6, 1994.

A  table indicating the stock options granted to Named Officers and
directors is included under the heading "Stock Option Plans" below.

The Company does not pay directors' fees.  Rather, the Compensation
Committee  of  the  Company's Board of Directors is  authorized  to
consider the grant of non-qualified stock options to members of the
Board,  consistent with the Company's philosophy  of  incentivizing
directors to foster, contribute to and participate in the Company's
growth.

Employment Agreements
The  Company  has  an  employment agreement  with  Max  W.  Batzer,
pursuant  to which Mr. Batzer is to serve as Chairman of the  Board
and  Chief  Executive Officer of the Company through  December  31,
2001.   The employment agreement provides for a minimum base salary
of $360,000 per annum, and benefits comparable to those provided to
other Company employees.  Although Mr. Batzer presently devotes his
full business time to the Company, his employment agreement permits
him to engage in other business activities that are not competitive
with  the  business  of  the Company and  that  do  not  materially
interfere  with  his performance of his duties and responsibilities
to the Company.


                                23

The  Company  has  an  employment agreement with  Brad  A.  Hummel,
pursuant  to  which Mr. Hummel is to serve as President  and  Chief
Operating  Officer of the Company through December  31,  2001.   In
February  1994,  Mr.  Hummel  also  assumed  the  duties  of  Chief
Financial Officer of the Company, upon the resignation of the prior
CFO.   The employment agreement provides for a minimum base  salary
of $270,000 per annum, and benefits comparable to those provided to
other  Company employees.  The agreement further provides  for  Mr.
Hummel  to  devote substantially all of his business  time  to  the
performance of his duties and responsibilities to the Company.

Each  of Mr. Batzer's and Mr. Hummel's employment agreements grants
to  the subject employee the right to elect, within one year  after
any  change  in control of the Company, to terminate his employment
on  not  less  than 90 days' prior written notice,  and  thereafter
receive his salary and benefits for a period of 24 months or to the
scheduled  expiration date of such employment agreement  (whichever
is  later).   Such  salary continuation is also applicable  in  the
event  that  the  Company  terminates such individual's  employment
(other  than  "for  cause") within one year  after  any  change  in
control of the Company.  For purposes of such agreements, a "change
in  control"  is deemed to occur at such time as 40% of  the  total
outstanding votes eligible to vote for directors of the Company are
owned  (legally or beneficially) by any person (or group of persons
acting in concert) who was not a stockholder of the Company  as  of
December 5, 1994.

The  Company also has employment agreements with James R. Angelica,
Bonnie  G. Lankford and Carol J. Gannon.  Mr. Angelica's employment
agreement  (as  amended) calls for him to serve as  a  Senior  Vice
President of the Company through August 31, 1997, at a base  salary
of  $85,000 per annum, and benefits comparable to those provided to
other  Company employees.  Ms. Lankford's employment agreement  (as
amended) calls for her to serve as Senior Vice President-Operations
of  the Company through December 31, 1999, at a minimum base salary
of $110,000 per annum, and benefits comparable to those provided to
other  Company employees.  Ms. Gannon's employment agreement  calls
for  her  to serve as Senior Vice President - Clinical Services  of
the  Company  through December 31, 1998, and provides for  a  fixed
annual  salary  of  $85,000 per annum, and benefits  comparable  to
those provided  to other Company employees.

Any  increases  in  the  annual rates of  compensation  of  Messrs.
Batzer, Hummel and Angelica under their employment agreements  must
be  approved by a majority of both the disinterested directors  and
the Compensation Committee of the Company's Board of Directors.

Stock Option Plans
On  April  15,  1992, the stockholders of the Company approved  the
Company's  1992  Stock Option Plan, as previously  adopted  by  the
Company's Board of Directors (the "1992 Plan"), pursuant  to  which
officers, directors, and/or key employees and/or consultants of the
Company can receive incentive stock options and non-qualified stock
options  to  purchase up to an aggregate of 903,509 shares  of  the
Company's Common Stock (of which no more than 180,702 shares may be
pursuant  to  qualified incentive stock options, and no  more  than
722,807  shares  may be pursuant to non-qualified  stock  options).
There are currently outstanding, under the 1992 Plan, stock options
for  an  aggregate  of 859,085 shares of common stock  at  exercise
prices  ranging  from  $.93 to $7.50 per  share,  and  expiring  at
various  times from January 1998 through April 2003.  The  weighted
average  exercise  price under such options is approximately  $1.80
per  share.   The


                                24
<PAGE>
 
exercise prices applicable under such outstanding
stock  options  represent not less than 100 % of  the  fair  market
value  of  the  underlying Common Stock as of the  date  that  such
options were granted, as determined from the closing bid price most
recently  quoted in the over-the-counter "pink sheets"  or  on  the
National   Association  of  Securities  Dealers,  Inc.    Automated
Quotation  System  ("NASDAQ") prior to the date that  such  options
were granted.

With  respect  to incentive stock options, the 1992  Plan  provides
that  the exercise price of each such option must be at least equal
to  100 % of the fair market value of the Common Stock on the  date
that such option is granted (and 110 % of fair market value in  the
case  of  stockholders who, at the time the option is granted,  own
more  than 10% of the total outstanding Common Stock), and requires
that  all such options have an expiration date not later than  that
date  which is one day before the tenth anniversary of the date  of
the grant of such options (or the fifth anniversary of the date  of
grant  in  the  case of 10 % stockholders).  However, with  certain
limited  exceptions, in the event that the option holder ceases  to
be  associated with the Company, or engages in or is involved  with
any  business similar to that of the Company, such option  holder's
incentive  options  immediately terminate.  Pursuant  to  the  1992
Plan, the aggregate fair market value, determined as of the date(s)
of  grant,  for which incentive stock options are first exercisable
by  an  option  holder during any one calendar year  cannot  exceed
$100,000.

With respect to non-qualified stock options, the 1992 Plan requires
that  the  exercise price of all such options be at least equal  to
100%  of the fair market value of the Common Stock on the date such
option  is  granted,  provided that non-qualified  options  may  be
issued at a lower exercise price (but in no event less than 85%  of
fair market value) if the net pre-tax income of the Company in  the
full  fiscal  year immediately preceding the date of the  grant  of
such  option  (the "Prior Year") exceeded 125% of the  mean  annual
average  net  pre-tax income of the Company for  the  three  fiscal
years immediately preceding such Prior Year.  Non-qualified options
must have an expiration date not later than that date which is  the
day  before the eighth anniversary of the date of the grant of  the
subject option.  However, with certain limited exceptions,  in  the
event  that  the  option holder ceases to be  associated  with  the
Company,  or  engages  in  or becomes involved  with  any  business
similar  to that of the Company, such option holder's non-qualified
options immediately terminate.

The  1992 Plan further provides that non-qualified options may (but
need  not) include a provision that, in the event of any change  in
control  and management of the Company or any sale of the  business
of the Company, except to the extent that the subject option holder
affirmatively  elects, during a limited period  of  time  following
such  event,  to permanently revoke and terminate the subject  non-
qualified  option (in whole or in part) and/or to reaffirm  all  or
any  portion of such non-qualified option without giving effect  to
the   reduction  in  exercise  price  herein  described,  then  the
otherwise  applicable exercise price in respect of such option  may
thereafter be reduced (but not by more than 50%) in the event that,
and  at  such  time(s)  as,  the subject option  holder  thereafter
exercises  such  option  (or  the  non-revoked  and  non-reaffirmed
portion  thereof,  as  the case may be).  All  but  39,000  of  the
690,935  outstanding   non-qualified options under  the  1992  Plan
contain  such provision, and this could have the effect of delaying
or  hindering  potential change in control  or  sale  transactions,
and/or  providing additional compensation or consideration  to  the
subject option holders in connection with any such transaction that
may be consummated.

In  April 1995, in response to the substantial increase in the size
of  the Company and its labor force, the Board of Directors of  the
Company adopted and approved the Company's 1995 Non-Qualified Stock
Option  Plan  (the  "1995 Non-Qualified Plan"), pursuant  to  which
officers, directors, and/or key employees and/or consultants of the
Company can receive non-qualified stock options to purchase  up  to
an  aggregate of 500,000 shares of the Company's common stock.  The
exercise  price,  expiration date and other terms  of  any  options
granted under the 1995 Non-Qualified Plan are substantially similar
to  the requirements applicable to non-qualified options under  the
1992  Plan.  There are currently outstanding, under the  1995  Non-
Qualified Plan, stock options for an aggregate of 454,625 shares of
common  stock  at exercise prices ranging from $1.93 to  $6.25  per
share,  and  expiring at various times from December  2000  through
January  2005.   The  weighted average exercise  price  under  such
options  is $4.14 per share.  Of the outstanding options under  the
1995  Non-Qualified Plan, 60,000 (exercisable at $5.25  per  share)
are  subject  to  certain contingencies relating to  the  Company's
earnings,   and  225,000  other  options  contain  price  reduction
provisions similar to those described in the immediately  preceding
paragraph.

The Company also maintains a 1995 Incentive Stock Option Plan ("the
1995 Incentive Plan"), as approved by the Company's stockholders on
November  22, 1995, pursuant to which key employees of the  Company
can  receive incentive stock options to purchase up to an aggregate
of 500,000 shares of common stock of the Company.  The requirements
of  the  1995  Incentive Plan are substantially  identical  to  the
provisions  of  the 1992 Plan which are specifically applicable  to
incentive  stock options, except that the 1995 Incentive Plan  will
expire on August 31, 2005 (after which date no further options  may
be  granted  under the 1995 Incentive Plan).  On the date  of  this
report,  61,750  options are  outstanding  under the 1995 Incentive 
Plan  at an  exercise price of $6.25 per share and expiring on July 
17, 2001.

In  January 1997, the Board of Directors of the Company adopted the
Company's  1997  Non-Qualified Stock Option Plan  (the  "1997  Non-
Qualified Plan"), pursuant to which officers, directors and/or  key
employees  and/or  consultants  of the  Company  can  receive  non-
qualified stock options to purchase up to an aggregate of 1,000,000
shares   of  the  Company's  Common  Stock.   The  exercise  price,
expiration  date and other terms of any options granted  under  the
1997   Non-Qualified  Plan  are  substantially   similar   to   the
requirements  applicable to non-qualified options  under  the  1992
Plan.   Options for an aggregate of 345,000 shares of Common  Stock
have  been issued and are outstanding  under the 1997 Non-Qualified 
Plan  at  an  exercise  price  of  $7.44 per  share and expiring on 
January 2,  2005.   235,000 of such options contain price reduction 
provisions similar to those described above.

Prior  to  April  16, 1993, the 1992 Plan was administered  by  the
Company's  Board  of  Directors.   Beginning  on  April  16,  1993,
administration  of the 1992 Plan was delegated to the  Compensation
Committee  of  the  Company's Board of Directors,  which  has  wide
discretion in determining the recipients of options, the amounts of
options  awarded, and various other terms and conditions applicable
to  options  granted  under the 1992 Plan.  The 1995  Non-Qualified
Plan,  the 1995 Incentive Plan and the 1997 Non-Qualified Plan  has
at all times been administered by the Compensation Committee, which
has  similar  wide  discretion in the administration  thereof.   In
determining  whether  and  to  what extent  specific  employees  or
consultants  will  be  awarded options, the Compensation  Committee
takes  into account the value of the specific individual's services
to  the  Company, the individual's time in service,  the  long-term
prospects  for the individual to handle additional responsibilities
within  the  Company,  and such other factors as  the  Compensation
Committee  may  deem relevant in order to reward and  motivate  the
Company's employees and consultants.

ITEM 12.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

In October 1989, Max W. Batzer, Thomas M. Sestak and Brad A. Hummel
borrowed  $66,000,  $10,000  and $33,000,  respectively,  from  the
Company.   The  proceeds of these loans were  utilized  by  Messrs.
Batzer, Sestak and Hummel to purchase shares of common stock.   The
loans  were amended and restated as of January 1, 1993,  such  that
the  loans now bear simple interest at a certain bank's prime  rate
(adjusted annually for purposes of the loans), with payment of  all
principal  and  accrued  interest due on December  31,  1997.   Mr.
Sestak's loan was repaid in full in October 1993.  Mr. Batzer's and
Mr.  Hummel's  loans are non-recourse, and are  secured  solely  by
shares  of common stock of the Company  having an aggregate  market
value  equal  to 50% of the outstanding loan obligations  (provided
that  the number of shares pledged as collateral will never  exceed
the number of shares (185,265 in the case of Mr. Batzer, and 92,633
in  the  case  of  Mr. Hummel) purchased with the proceeds  of  the
loans.   The  Company  has retained a right  of  first  refusal  in
connection with any proposed sale of the pledged shares while  they
remain  subject to such pledge, although the Company is prohibited,
under its loan agreement with TCB, to redeem or purchase any shares
of its common stock without TCB's prior consent.

In  April  1996, in connection with the Company's private placement
of the Bridge Notes and Bridge Warrants, an aggregate of $50,000 of
Bridge  Notes and 2,500 Bridge Warrants were purchased by James  R.
Angelica,  $100,000 of Bridge Notes and 5,000 Bridge Warrants  were
purchased   by  Thomas M. Sestak, and $50,000 of Bridge  Notes  and
2,500 Bridge Warrants were purchased by Carol J. Gannon.

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

                      1997 NONQUALIFIED STOCK OPTION PLAN
                      -----------------------------------



     1.   Purposes.
          -------- 

          The purposes of the Diagnostic Health Services, Inc. 1997 Nonqualified
Stock Option Plan (this "Plan") are to aid Diagnostic Health Services, Inc. (the
"Company") and its subsidiaries in attracting and retaining capable management
and employees and to enable officers, directors, employees and/or consultants of
the Company and its subsidiaries to acquire or increase ownership interest in
the Company on a basis that will encourage them to perform at increasing levels
of effectiveness and use their best efforts to promote the growth and
profitability of the Company and its subsidiaries.  Consistent with these
objectives, this Plan authorizes the granting to officers, directors, employees
and/or consultants of options (collectively, "Options") to acquire shares of the
Company's common stock, $.001 par value per share ("Common Stock"), pursuant to
the terms and conditions hereinafter set forth.  As used herein, the term
"subsidiary" has the same meaning as is ascribed to the term "subsidiary
corporation" under Section 425 of the Internal Revenue Code of 1986, as amended
(the "Code").

          Options granted hereunder are not intended to be and shall not be
treated as "incentive stock options" within the meaning of Section 422 of the
Code.
<PAGE>
 
     2.   Effective Date.
          -------------- 

          This Plan shall become effective upon the adoption and approval hereof
by the Board of Directors of the Company (the "Board").

     3.   Administration.
          -------------- 

          (a) This Plan shall be administered by the Compensation Committee
of the Board, or, if no Compensation Committee shall then be constituted, a
committee consisting of three members of the Board who are selected by the Board
(in either case, the "Committee"); provided, however, that in the event that,
                                   --------  -------  
and for so long as, the entire Board shall consist of only three members, then
the Board shall constitute the Committee hereunder. If, at any time, there are
less than three members of the Committee eligible to serve in such capacity, the
Board shall appoint one or more other eligible members of the Board to serve on
the Committee. All Committee members shall serve, and may be removed, at the
pleasure of the Board.

          (b) A majority of the members of the Committee (but not less than two)
shall constitute a quorum, and any action taken by a majority of such members
present at any meeting at which a quorum is present, or acts approved in writing
by all such members, shall be the acts of the Committee.

          (c) Subject to the other provisions of this Plan, the Committee shall 
have full authority to decide the date or dates on which Options will be granted
under this Plan (in each instance, the "Date of Grant"), to select the officers,
directors, employees and/or consultants to whom Options will be granted, to
determine the number of shares of Common Stock to be covered by each Option, the
price at which such shares may be purchased upon the exercise of such Option
(the "Exercise Price") and other terms and conditions of such purchase.  In
making such determinations, the Committee shall solicit the recommendations of
the Chairman and President of the Company and may take into account each
proposed optionee's present and potential contributions to the Company's
business and any other factors which the Committee may deem relevant.  Subject
to the other provisions of this Plan, the Committee shall also have full
authority to (i) interpret this Plan and any stock option agreements evidencing
Options granted

                                      -2-
<PAGE>
 
hereunder ("Option Agreements"), (ii) issue rules for administering this Plan,
(ii) change, alter, amend or rescind such rules, and (iv) make all other
determinations necessary or appropriate for the administration of this Plan. All
determinations, interpretations and constructions made by the Committee pursuant
to this Section 3 shall be final and conclusive. No member of the Board or the
Committee shall be liable for any action, determination or omission taken or
made in good faith with respect to this Plan or any Option granted hereunder.

     4.   Eligibility.
          ----------- 

          (a) All officers, directors, employees and/or consultants of the
Company (as determined by the Committee) shall be eligible to receive Options
under this Plan.

          (b) Anything elsewhere contained in this Plan to the contrary
notwithstanding, in no event and under no circumstances shall any Options be
granted under this Plan providing for an Exercise Price less than 100% of the
fair market value per share on the Date of Grant if the net pre-tax income of
the Company in the full fiscal year immediately preceding the Date of Grant of
such Option (the "Prior Year") did not exceed 125% of the mean average annual
net pre-tax income of the Company for the three fiscal years immediately
preceding the Prior Year; and in no event and under no circumstances (other than
by reason of any adjustment authorized herein to take place following the Date
of Grant) shall the Exercise Price under any Option on the Date of Grant of such
Option be less than 85% of the fair market value per share on such Date of
Grant.  For purposes hereof, the Company's net pre-tax income for any fiscal
year shall be the consolidated net pre-tax income of the Company and its
subsidiaries as reflected in the Company's consolidated audited financial
statements for such fiscal year, which shall be prepared in accordance with
generally accepted accounting principles applied on a consistent basis
throughout all periods in question.

                                      -3-
<PAGE>
 
     5.   Option Shares.
          ------------- 

          (a) The shares subject to Options granted under this Plan shall be
shares of Common Stock and, except as otherwise required or permitted by Section
5(b) below, the aggregate number of shares with respect to which Incentive
Options may be granted hereunder shall not exceed 1,000,000 shares. If an Option
expires, terminates or is otherwise surrendered, in whole or in part, the shares
allocable to the unexercised portion of such Option shall again become available
for grants of Options hereunder. As determined from time to time by the Board,
the shares available under this Plan for grants of Options may consist either in
whole or in part of authorized but unissued shares of Common Stock or shares of
Common Stock which have been reacquired by the Company or a subsidiary following
original issuance.

          (b) The aggregate number of shares of Common Stock as to which
Options may be granted hereunder (as provided in Section 5(a) above), the number
of shares covered by each outstanding Option, and the Exercise Price applicable
to each outstanding Option shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a stock
split, recapitalization or other subdivision or consolidation of shares or other
adjustment, or the payment of a stock dividend in respect of the Common Stock;
provided, however, that any fractional shares resulting from any such adjustment
- --------  -------                                                               
shall be eliminated.

     6.   Terms and Conditions of Options.
          ------------------------------- 

          Each Option granted pursuant to this Plan shall be evidenced by an
Option Agreement between the Company and the officer, director, employee and/or
consultant to whom the Option is granted (the "Optionee") in such form or forms
as the Committee, from time to time, shall prescribe, which agreements may but
need not be identical to each other, but shall comply with and be subject to the
following terms and conditions:

                                      -4-
<PAGE>
 
     (a) Exercise Price.  The Exercise Price at which each share of Common
         --------------
Stock may be purchased pursuant to an Option shall be determined by the
Committee in accordancw with the requirements of this Plan, but shall in no
event be less than 85% of the fair market value for each such share on the Date
of Grant of such Option, determined by the Committee as aforesaid; provided,
                                                                   -------- 
however, that the Option Agreement in respect of any or all Options may (but
- -------      
need not) provide that, in the event of any change in control and management of
the Company or any sale of the business of the Company, except to the extent
that the subject Optionee (or other person entitled to exercise such Option)
affirmatively elects, during a limited period of time after receiving notice of
such event, to permanently revoke and terminate the subject Option (in whole or
in part) and/or to reaffirm all or any portion of such Option without giving
effect to the reduction in Exercise Price hereinafter described, then the
otherwise applicable Exercise Price in respect of such Option may thereafter be
reduced (but not by more than 50%) in the event that, and at such time(s) as,
the subject Optionee (or other person entitled to exercise such Option)
thereafter exercises such Option (or the non-revoked and non-reaffirmed portion
thereof, as the case may be). Anything contained in this Section 6(a) to the
contrary notwithstanding, in the event that the number of shares of Common Stock
subject to any Option is adjusted pursuant to Section 5(b) above, a
corresponding adjustment shall be made in the Exercise Price per share.

          (b) Duration of Options.  The duration of each Option granted
              ------------------- 
hereunder shall be determined by the Committee, but shall in no event be later
than that date which is the day before the eighth anniversary of the Date of
Grant of such Option, subject to extension by mutual written agreement of the
Company and the subject Optionee (in each instance, the "Expiration Date").

          (c) Vesting of Options.  The vesting of each Option granted hereunder
              ------------------                                               
shall be determined by the Committee, provided that, if no vesting requirements
are specified at the time of the granting of any Option hereunder, then the
subject Option shall be deemed to be fully vested and exercisable on the Date of
Grant.  Only the vested portion(s) of any Option may be exercised.

                                      -5-
<PAGE>
 
          (d) Merger, Consolidation, etc.  In the event that the Company shall,
              ---------------------------                                      
pursuant to action by the Board, at any time propose to merge into, consolidate
with, or sell or otherwise transfer all or substantially all of its assets to,
another corporation and provision is not made pursuant to the terms of such
transaction for (i) the assumption by the surviving, resulting or acquiring
corporation of all outstanding Options granted pursuant to this Plan, (ii) the
substitution of new options therefor, or (iii) the payment of cash or other
consideration in respect thereof, then the Committee shall cause written notice
of the proposed transaction to be given to each Optionee not less than thirty
(30) days prior to the anticipated effective date of the proposed transaction.
On a date which the Committee shall specify in such notice, which date shall be
not less than ten (10) days prior to the anticipated effective date of the
proposed transaction, each Optionee's Options shall become fully (100%) vested
and each Optionee shall have the right to exercise his or her Options to
purchase any or all shares then subject to such Options; and if the proposed
transaction is consummated, each Option, to the extent not previously exercised
prior to the effective date of the transaction, shall terminate on such
effective date.  If the proposed transaction is abandoned or otherwise not
consummated, then to the extent that any Option not exercised prior to such
abandonment shall have vested solely by operation of this Section 6(d), such
vesting shall be annulled and be of no further force or effect and the vesting
period otherwise established for or applicable to such Option pursuant to
Section 6(c) above shall be reinstituted as of the date of such abandonment;
provided, however, that nothing herein contained shall be deemed to
- --------  -------                                                  
retroactively affect or impair any exercise of any such vested Option prior to
the date of such abandonment.

          (e) Exercise of Options.  A person entitled to exercise an Option,
              ------------------- 
or any portion thereof, may exercise it (or such vested portion thereof) in
whole at any time, or in part from time to time, by delivering to the Company at
its principal office, directed to the attention of the President of the Company
or such other duly elected officer as shall be designated in writing by the
Committee to the Optionee, written notice specifying the number of shares of
Common Stock with respect to which the Option is being exercised, together with
payment in full of the aggregate Exercise Price for such shares. Such payment

                                      -6-
<PAGE>
 
shall be made in cash or by certified check or bank draft to the order of the
Company; provided, however, that the Committee may, in its sole discretion,
         --------  -------                                                 
authorize such payment, in whole or in part, in any other form, including
payment by personal check or by the exchange of shares of Common Stock owned of
record by the person entitled to exercise the Option and having a fair market
value on the date of exercise equal to the price for which the shares of Common
Stock may be purchased pursuant to the Option.

          (f) Non-Transferability.  Any Option granted hereunder may, if so
              -------------------
provided in the subject Option Agreement, be transferable to members of the
Optionee's immediate family or by will or by the laws of decent and
distribution, and may, if so provided in the subject Option Agreement, be
pledged as collateral security in favor of another permitted holder of an Option
hereunder, solely as collateral for a loan made by such other holder to the
person making such pledge.

          (g) Termination of Employment; Competition.  The following provisions
              --------------------------------------                           
shall apply in the event of an Optionee's engaging in competition with the
Company, or in the event of the termination of an Optionee's employment with the
Company or any of its subsidiaries:

               (i) In the event that an Optionee shall engage or participate in,
     or become involved with, in any manner or capacity (whether as employee,
     agent, consultant, advisor, officer, director, manager, partner, joint
     venturer, investor, shareholder (other than passive investments in less
     than 5% of the outstanding securities of any company) or otherwise), any
     business enterprise which is engaged in the rendering of diagnostic
     ultrasound services, nuclear imaging, cardiac lab management, paramedical
     personnel placement, or any other business conducted or operated by the
     Company on the date on which such Optionee first became involved with such
     other business enterprise, or in the event that an Optionee's employment
     with the Company or any of its subsidiaries shall be terminated either (A)
     by the Company or any of its subsidiaries for "Cause" (as defined in any
     applicable employment agreement to which such Optionee is a party), or (in
     the absence of a definition contained in any applicable employment
     agreement) for fraud, dishonesty,

                                      -7-
<PAGE>
 
     habitual drunkenness or drug use, for willful disregard of assigned duties
     or instructions by such Optionee, or for concrete actions causing
     substantial harm to the Company, or for other material breach by the
     Optionee of any applicable employment agreement to which the Optionee is a
     party, or (B) by the Optionee voluntarily and without the written consent
     of the Company, then all outstanding Options granted hereunder to such
                     ----                        
     Optionee shall automatically and immediately terminate at the time that
     notice of termination of employment is given, and shall not then or
     thereafter be exercisable in whole or in part; provided, however, that
                                                    --------  -------
     nothing herein contained shall be deemed to modify or amend the terms and
     conditions of any applicable employment agreement, including but not
     limited to the grounds upon which any Optionee's employment may be
     terminated.

               (ii) In the event that an Optionee's employment with the Company
     or any of its subsidiaries shall terminate (A) by reason of retirement, or
     (B) under circumstances other than those specified in Section 6(g)(i) above
     and for other than death or disability, then all outstanding Options
                                             ----     
     granted hereunder to such Optionee shall terminate three (3) months after
     the date of such termination of employment or on the Expiration Date,
     whichever shall first occur; provided, however, that if such Optionee
                                  --------  -------    
     dies within such three (3) month period, then all outstanding Options
     granted hereunder to such Optionee shall terminate on the first anniversary
     of such Optionee's death or on the Expiration Date, whichever shall first
     occur.

               (iii) In the event of the death or disability of an Optionee

               (iv) Anything contained in this Section 6 to the contrary
     notwithstanding, an Option granted pursuant to this Plan may only be
     exercised following the subject Optionee's termination of employment with
     the Company or any of its subsidiaries for reasons other than death,
     disability or retirement if, and to the extent that, such Option was
     exercisable immediately prior to such termination of employment.

               (v) An Optionee's transfer of employment between the Company and
     any of its subsidiaries or between subsidiaries shall not constitute a
     termination of employment, and the Committee shall determine in each case
     whether an authorized leave of absence for professional education, military
     service or otherwise shall constitute a termination of employment.

               (vi) Nothing contained in this Section 6(g) shall be deemed to
     modify or affect any vesting schedule provided in any Option Agreement,
     which vesting schedule shall continue in effect and be applied and enforced
     notwithstanding any modification of the exercise period arising by reason
     of the application of this Section 6(g).

          (h) No Rights as a Stockholder or to Continued Employment.  No
              ----------------------------------------------------- 
Optionee shall have any rights as a stockholder of the Company with respect to
any shares covered by an Option prior to the date of issuance to such Optionee
of the certificate or certificates for such shares. Neither this Plan nor any
Option granted hereunder shall confer upon an Optionee any right to continued
employment by the Company or any of its subsidiaries or interfere in any way
with the right of the Company or its subsidiaries to terminate the employment of
such Optionee (subject to the terms and conditions of any applicable employment
agreement between the Company or any of its subsidiaries and the subject
Optionee).

          (i) Designation.  Each Option Agreement entered into pursuant to this
              -----------   
Plan shall specify therein that the subject Option has been granted under this
Plan.

              --------------------------                                    
pursuant to this Plan may contain such further terms and conditions (including a
right of first refusal in favor of the Company in the event that the Optionee
shall seek to transfer any shares acquired upon exercise of the subject Option)
as the Committee may determine, provided that such other terms and conditions
are not in violation of, in conflict with or otherwise inconsistent with the
requirements of this Plan.

     7.   Issuance of Shares; Restrictions.
          -------------------------------- 

          (a) Subject to the conditions, restrictions and other qualifications
provided in this Section 7, the Company shall, within thirty (30) business days
after an Option has been duly exercised in whole or in part, deliver to the
person who exercised the Option one or more certificates, registered in the name
of such person, for the number of shares of Common Stock with respect to which
the Option has been exercised.  The Company may legend any stock certificate
issued hereunder to reflect any restrictions provided for in this Section 7,
including but not limited to a "stop transfer" legend pursuant to Section 7(b)
below.

          (b) Unless the shares subject to Options granted under the Plan have
been registered under the Securities Act of 1933, as amended (the "Act") (and,
if the person exercising the Option may be deemed an "affiliate" of the Company
as such term is defined in Rule 405 under the Act, such shares have been
registered under the Act for resale by such person), or the Company has
determined that an exemption from registration under the Act is available, the
Company may require, prior to and as a condition of the issuance of any shares
of Common Stock upon exercise of any Option, that the person exercising such
Option hereunder furnish the Company with a written representation in a form
prescribed by the Committee to the effect that such person is acquiring such
shares solely with a view to investment for his or her own account and not with
a view to the resale or distribution of all or any part thereof, and that such
person will not dispose of any of such shares otherwise than in accordance with
the provisions of Rule 144 under the Act unless and until either the sale or
distribution of such shares is registered under the Act or the Company is
satisfied that an exemption from such registration is available.

                                      -10-
<PAGE>
 
          (c) Anything herein contained to the contrary notwithstanding, the
Company shall not be obligated to sell or issue any shares of Common Stock
pursuant to the exercise of an Option granted hereunder unless and until the
Company is satisfied that such sale or issuance complies with all applicable
provisions of the Act and all other laws and/or regulations by which the Company
is bound or to which the Company or such shares may be subject; and the Company
reserves the right to delay the issuance and/or delivery of shares of Common
Stock for such period of time as may be required in order to effect compliance
with the applicable provisions of the Act and all other applicable laws and/or
regulations as aforesaid.

     8.   Substitute Options.
          ------------------ 

          Anything herein contained to the contrary notwithstanding, Options
may, at the discretion of the Board, be granted under this Plan in substitution
for options to purchase shares of capital stock of another corporation which is
merged into, consolidated with or all or a substantial portion of the property
or stock of which is acquired by, the Company or a subsidiary.  The terms,
provisions and benefits to each Optionee under such substitute Options shall in
all respects be identical to the terms, provisions and benefits to such Optionee
of his or her options of the other corporation on the date of substitution,
except that such substitute Options shall provide for the purchase of shares of
Common Stock of the Company instead of shares of such other corporation.

     9.   Term of this Plan.
          ----------------- 

          Unless this Plan has been sooner terminated pursuant to Section 10
below, this Plan shall terminate on, and no Options hereunder shall be granted
after, the tenth (10th) anniversary of the date of the adoption and approval of
this Plan by the Board.  Notwithstanding any such Plan termination, the
provisions of this Plan shall nonetheless continue thereafter to govern all
Options theretofore granted (including but not limited to any Options the
Expiration Date of which is extended to any date subsequent to the termination
of this Plan) until the exercise, expiration or cancellation of such Options.

     10.  Amendment and Termination of Plan.
          --------------------------------- 

          The Board may at any time terminate this Plan, or amend this Plan from
time to time in such respects as the Board deems desirable; provided, however,
                                                            --------  ------- 
that, subject to the provisions of Sections 6 and 7 above, no termination hereof
or amendment hereto shall adversely affect the rights of an Optionee or other
person holding an Option theretofore granted hereunder without the consent of
such Optionee or other person, as the case may be.

     issued or accepted by banks and other financial institutions for account of
     Borrower or a Guarantor; (v) capital lease obligations; and (vi) Funded
     Debt of others guaranteed by Borrower or a Guarantor.

     calculated as if the proposed Acquisition then under consideration has been
     consummated on the date of calculation on the terms proposed by Borrower or
     the subject Guarantor.

               For purposes of determining the commitment fees earned and
     payable in accordance with Section 7 and the Eurodollar Margin and the
     Prime Rate Margin (each a "Margin," and, collectively, the "Margins"), the
     Funded Debt Ratio is subject to adjustment quarterly (by increase or
     decrease, as appropriate), effective only as of the first day of the
     calendar month next following the month in which Borrower delivers a
     Compliance Certificate (in the form of ExhibitD) contemporaneously with the
     quarterly financial information delivered to Bank pursuant to Section
     11(a)(ii) (each such day, an "Adjustment Date"). (For example, the
     commitment fee and the Margins shall adjust effective September 1, 1997
     based on financial information for the fiscal quarter ending June 30, 1997
     delivered to Bank on or about August 14, 1997.) After each adjustment of
     the commitment fee or the Margins resulting from an adjustment in the
     Funded Debt Ratio, in accordance herewith, each such commitment fee shall
     thereafter apply, or each such Margin shall thereafter apply to all Loans
     then outstanding or made (i.e., with no retroactivity), until the next
     Adjustment Date that a Compliance Certificate delivered contemporaneously
     with quarterly financial information required pursuant to Section 11(a)(ii)
     demonstrates a change in the Funded Debt Ratio such that other commitment
     fees or Margins apply. Upon request of Bank, Borrower shall demonstrate to
     the reasonable satisfaction of Bank the numerically required applicable
     ratio in order to obtain an adjustment to a lower applicable commitment fee
     or Margin. If Borrower fails to furnish to Bank any Compliance Certificate
     by the date required by this Agreement, then the maximum commitment fees
     shall thereafter apply, or the maximum Margins shall thereafter apply to
     all Loans then outstanding or made (i.e., with no retroactivity), until
     Borrower furnishes the required Compliance Certificate to Bank.

               For purposes of this Agreement, as of the date hereof, the Prime
     Rate Margin is one-half of one percent (0.50%) and the Eurodollar Rate
     Margin is two percent (2.00%) and each will remain such until an adjustment
     to the Margins is made in accordance with

     principal and, to the extent permitted by law, past due interest in respect
     to a Prime Rate Loan, shall bear interest, payable on demand, at a rate per
     annum equal to the Prime Rate plus four percent (4%).
                                   ----                   

(ii) Eurodollar Loans.  With respect to the unpaid principal amount of a
     ----------------                                                   
     Eurodollar Loan, Borrower agrees to pay interest calculated on the basis of
     the actual days elapsed (including the first day but excluding the last
     day) in a year consisting of 360 days (unless such calculation would result
     in a usurious rate, in which case interest shall be calculated on the basis
     of a year or 365 or 366 days, as the case may be) from the date the
     proceeds thereof are made available to Borrower until

AMENDED AND RESTATED LOAN AGREEMENT - Page 20
<PAGE>
 
      maturity (whether by acceleration or otherwise), at a varying rate per 
      annum equal to the lesser of (i) the Maximum Rate, or (ii) the 
      Eurodollar Rate plus the Eurodollar Margin.  Past due principal and, to 
                      ----               
     the extent permitted by law, past due interest shall bear interest, payable
     on demand, at a rate per annum equal to the Prime Rate plus four percent
                                                            ----         
     (4%).

(iii)  Exercise of Option.  No more than a total of three (3) Eurodollar Loans
       ------------------                                                     
shall be outstanding at any one time in respect of the Advance Term Loan and the
Revolving Loan.  In addition, the principal amount of each Eurodollar Loan shall
be at least $1,000,000.  Without Bank's prior written consent, no continuation
or conversion, as applicable, shall be made of a Eurodollar Loan if in
connection with required regular principal payments on the Advance Term Note,
such continuation or conversion would cause Borrower to be required to make
payments pursuant to Section 5(g).

(b)  Interest Rate Determination.  Bank shall determine each interest rate
     ---------------------------                                          
     applicable to the Notes hereunder in accordance with this Section 4.  Bank
     shall give prompt notice to Borrower of each Eurodollar Rate so determined
     and its determination thereof shall be conclusive absent manifest error.

(c)  Initial Option/Conversion/Continuation Option.  With respect to each new
     ---------------------------------------------                           
     Advance, Borrower shall in writing request that the same be a Eurodollar
     Loan, or a Prime Rate Loan, at the time Borrower submits an Advance Request
     therefor.  Thereafter, subject to Section 5 and Borrower's and Guarantors'
     compliance with their other obligations under this Agreement, Borrower may
     elect from time to time:

          (i) to convert a Eurodollar Loan to a Prime Rate Loan by giving Bank
irrevocable notice of such election (in writing in the form of an Interest
Option Request in the form of Exhibit E) prior to 10:00 a.m. (Dallas, Texas
time) on the conversion date and such conversion shall be made on the requested
conversion date, provided that any such conversion of a Eurodollar Loan shall
only be made on the last day of the Eurodollar Interest Period with respect
thereto; or

          (ii) to convert a Prime Rate Loan to a Eurodollar Loan, or continue a
Eurodollar Loan as a Eurodollar Loan, by giving Bank irrevocable notice of such
election (in writing in the form of an Interest Option Request in the form of
ExhibitE) three (3) Eurodollar Business Days prior to the proposed conversion
and, subject to Section5 and Borrower's and Guarantors' compliance with their
other obligations under this Agreement, such conversion shall be made on the
requested conversion date, or if such requested conversion date is not a
Eurodollar Business Day, on the next succeeding Eurodollar Business Day.


AMENDED AND RESTATED LOAN AGREEMENT - Page 21
<PAGE>
 
     Any such conversion shall not be deemed to be a prepayment of any of the
Loans for purposes of this Agreement.  If Bank shall not have received timely
notice as herein provided with respect to the continuation or conversion of an
expiring Eurodollar Interest Period, then Borrower shall be deemed to have
elected to convert any maturing Eurodollar Loan to a Prime Rate Loan.

(d)  Recoupment.  If at any time the applicable rate of interest selected
     ----------                                                          
     pursuant to Sections 4(a)(i) or 4(a)(ii) above shall exceed the Maximum
     Rate, thereby causing the interest on one or more of the Notes to be
     limited to the Maximum Rate, then any subsequent reduction in the interest
     rate so selected or subsequently selected shall not reduce the rate of
     interest on such Notes below the Maximum Rate until the total amount of
     interest accrued on such Notes equals the amount of interest that would
     have accrued on the Note if the rate or rates selected pursuant to Sections
     4(a)(i) or 4(a)(ii), as the case may be, had at all times been in effect.

5.   Special Provisions Relating to Eurodollar Loans.

(a)  Unavailability of Funds or Inadequacy of Pricing.  If, in connection with
     ------------------------------------------------                         
     any proposed Eurodollar Loan, Bank (i) shall have determined that U.S.
     Dollar deposits of the relevant amount and for the relevant Eurodollar
     Interest Period for any Eurodollar Loan are not available to Bank in the
     London interbank market; or (ii) in good faith determines that the
     Eurodollar Interest Rate will not adequately reflect the cost to Bank of
     maintaining or funding a Eurodollar Loan for such Interest Period, then in
     either case the obligations of Bank to make a Eurodollar Loan shall be
     suspended until such time as Bank in its sole discretion reasonably
     exercised determines that the event resulting in such suspension has ceased
     to exist.  If Bank shall make such determination it shall promptly notify
     Borrower in writing and Borrower shall either repay any outstanding
     Eurodollar Loan owed to Bank, without penalty, on the last day of the
     current Eurodollar Interest Period, or convert the same to a Prime Rate
     Loan on the last day of the then current Eurodollar Interest Period for
     such Eurodollar Loan.

(b)  Reserve Requirements.  Upon any change in any applicable law, treaty or
     --------------------                                                   
     regulation or in the interpretation or administration thereof, or if any
     central bank or other fiscal monetary or other authority having
     jurisdiction over Bank or the loans contemplated by this Agreement shall
     impose, modify or deem applicable any reserve requirement of the Board of
     Governors of the Federal Reserve System on any Eurodollar Loan, or any
     other reserve, special deposit, or similar requirements against assets or
     deposits with or for the account of, or credit extended by, Bank or shall
     impose on Bank, Eurodollar interbank markets in general or the London
     interbank market specifically, as the case may be, any other condition
     affecting this Agreement or any Eurodollar Loan and the result of any of
     the foregoing is to increase the cost to Bank in making or maintaining a
     Eurodollar Loan or to reduce any amount (or the effective return on any
     amount) received by Bank hereunder, then Borrower shall either (i) pay to
     Bank upon


AMENDED AND RESTATED LOAN AGREEMENT - Page 22
<PAGE>
 
     demand of Bank as additional interest on the Advance Term Note or the
     Revolving Note, as the case may be, evidencing a Eurodollar Loan such
     additional amount or amounts as will reimburse Bank for such additional
     cost or such reduction or (ii) convert such Eurodollar Loan to a Prime Rate
     Loan. Bank shall give notice to Borrower upon becoming aware of any such
     change or imposition which may result in any such increase or reduction. A
     certificate of Bank setting forth the basis for the determination of such
     amount necessary to compensate Bank as aforesaid shall be delivered to
     Borrower and shall be conclusive as to such determination and such amount,
     absent manifest error.

(c)  Taxes.  Both principal and interest on the Advance Term Note or the
     -----                                                              
     Revolving Note, as the case may be, evidencing any Eurodollar Loan are
     payable without withholding or deduction for or on account of any taxes.
     If any taxes (other than taxes based on the overall net income of Bank) are
     levied or imposed on or with respect to the Advance Term Note or the
     Revolving Note, as the case may be, evidencing a Eurodollar Loan or on any
     payment on the Advance Term Note or the Revolving Note, as the case may be,
     evidencing a Eurodollar Loan made to Bank, then, and in any such event,
     Borrower shall pay to Bank upon demand of Bank such additional amounts as
     may be necessary so that every net payment of principal and interest on the
     Advance Term Note or the Revolving Note, as the case may be, evidencing a
     Eurodollar Loan, after withholding or deduction for or on account of any
     such taxes, will not be less than any amount provided for herein.  In
     addition, if at any time when any Eurodollar Loan is outstanding any laws
     enacted or promulgated, or any court of law or governmental agency
     interprets or administers any law, that, in any such case, materially
     changes the basis of taxation of payments to Bank of principal of or
     interest on the Advance Term Note or the Revolving Note, as the case may
     be, evidencing a Eurodollar Loan by reason of subjecting such payments to
     double taxation or otherwise (except through an increase in the rate of tax
     on the overall net income of Bank) then Borrower will pay upon demand by
     Bank the amount of loss to the extent that such loss is caused by such a
     change.  Bank shall give notice to Borrower upon becoming aware of the
     amount of any loss incurred by Bank through enactment or promulgation of
     any such law that materially changes the basis of taxation of payments to
     Bank.  Bank shall also give notice on becoming aware of any such enactment
     or promulgation that may result in such payments becoming subject to double
     taxation or otherwise.  A certificate of Bank setting forth the basis for
     the determination of such loss and the computation of such amounts shall be
     delivered to Borrower and shall be conclusive of such determination and
     such amount, absent manifest error.

(d)  Change in Laws.  If at any time any new law or any change in existing laws
     --------------                                                            
     or in the interpretation of any new or existing laws shall make it unlawful
     for Bank to maintain or fund a Eurodollar Loan hereunder, then Bank shall
     promptly notify Borrower in writing and Borrower shall either (i) repay any
     outstanding Eurodollar Loan owed to Bank, without penalty, on the last day
     of the current Eurodollar Interest Period (or, if Bank may not lawfully
     continue to maintain and fund such Eurodollar Loan,

AMENDED AND RESTATED LOAN AGREEMENT - Page 23
<PAGE>
 
     immediately), or (ii) Borrower may convert such Eurodollar Loan at such
     appropriate time to a Prime Rate Loan.

(e)  Option to Fund.  Bank shall have the option if Borrower elects a Eurodollar
     --------------                                                             
     Loan, to purchase one or more deposits in order to fund or maintain its
     funding of the principal balance of a Note to which such Eurodollar Loan is
     applicable during the Eurodollar Interest Period in question; it being
     understood that the provisions of this Agreement relating to such funding
     are included only for the purpose of determining the rate of interest to be
     paid under such Eurodollar Loan and any amounts owing hereunder.  Bank
     shall be entitled to fund and maintain its funding of all or any part of
     that portion of the principal balance of either Note in any manner it sees
     fit, but all such determinations hereunder shall be made as if Bank have
     actually funded and maintained that portion of the principal balance of
     either Note to which a Eurodollar Loan is applicable during the applicable
     Eurodollar Interest Period through the purchase of deposits in an amount
     equal to the principal balance of the Note to which such Eurodollar Loan is
     applicable and having a maturity corresponding to such Eurodollar Interest
     Period.  Bank may fund the outstanding principal balance of either Note
     which is to be subject to any Eurodollar Loan from any branch or office of
     Bank as Bank may designate from time to time.

(f)  Indemnity.  Borrower shall indemnify and hold harmless Bank against all
     ---------                                                              
     reasonable and necessary out-of-pocket costs and expenses (which costs and
     expenses are not intended to include, without limitation, any loss
     sustained by Bank in connection with the borrowing or reemployment of funds
     with respect to any Eurodollar Loan) which Bank may sustain (i) if (other
     than as a result of a default by Bank hereunder) the making of any loan or
     loans as a Eurodollar Loan does not occur on the date, if any, specified
     therefor in the notice given by Borrower pursuant to Section 4(c), (ii) as
     a consequence of any default by Borrower under this Section 5, or (iii) any
     other loss suffered by Bank as a result of the making of any Loan as a
     Eurodollar Loan.

(g)  Payments Not at End of Eurodollar Interest Period.  If Borrower makes any
     -------------------------------------------------                        
     payment of principal with respect to any Eurodollar Loan on any day other
     than the last day of the Eurodollar Interest Period applicable to such
     Eurodollar Loan, then, except in connection with a mandatory prepayment in
     accordance with Section 8(b), Borrower shall reimburse Bank on demand for
     any loss, cost or expense incurred by Bank as a result of the timing of
     such payment or in redepositing such principal amount, including the sum of
     (i) the cost of funds to Bank in respect of such principal amount so paid,
     for the remainder of the Eurodollar Interest Period applicable to such sum,
     reduced, if Bank is able to redeposit such principal amount so paid for the
     balance of the Eurodollar Interest Period, by the interest earned by Bank
     as a result of so redepositing such principal amount, plus (ii) any expense
     or penalty incurred by Bank in redepositing such principal amount.  A
     certificate of Bank setting forth the basis for the determination

AMENDED AND RESTATED LOAN AGREEMENT - Page 24
<PAGE>
 
     of the amount owed by Borrower pursuant to this Section 5(g) shall be
     delivered to Borrower and shall be conclusive in the absence of manifest
     error.

6.   Collateral Security and Guaranties.  Borrower and each Guarantor hereby
confirm and acknowledge that the Liens previously granted to Bank in connection
with the Prior Agreement, to secure the performance of their obligations
thereunder, also secure the Obligations, whether now or hereafter incurred,
matured or unmatured, direct or contingent, joint or several, or joint and
several, including extensions, modifications and renewals thereof, and
substitutions therefor, and as such remain in force and full effect.
Additionally, Borrower acknowledges that in the Prior Agreement Borrower pledged
and delivered to Bank one hundred percent (100%) of the issued and outstanding
shares of the capital stock of DHS Management Services, Inc. ("DHSMS") and
ninety-nine percent (99%) of the issued and outstanding capital stock of
Diagnostic Health Services De Mexico, S.A. de C.V., and DHSMS pledged and
delivered, or caused its appropriate Subsidiary to pledge and deliver, to Bank
one hundred percent (100%) of the issued and outstanding shares of the capital
stock of each of its Subsidiaries (other than (i) Homecare International De
Mexico, S.A. de C.V., as to which DHSMS pledged and delivered its shares thereof
constituting one percent (1%) of the issued and outstanding shares thereof, and
caused Diagnostic Health Services de Mexico, S.A. de C.V., to pledge and deliver
shares thereof constituting ninety-nine percent (99%) (including after-acquired
shares) of the issued and outstanding shares thereof, and (ii) Diagnostic Health
Services De Mexico, S.A. de C.V., as to which DHSMS pledged and delivered its
shares thereof constituting one percent (1%) of the issued and outstanding
shares thereof).  Borrower and each Guarantor hereby confirm that each such
pledge secures the Obligations, whether now or hereafter incurred, matured or
unmatured, direct or contingent, joint or several, or joint and several,
including extensions, modifications and renewals thereof, and substitutions
therefor, and as such remain in force and full effect.  All collateral in which
Borrower or any Guarantor has herewith granted or hereafter grants to Bank a
Lien (to the satisfaction of Bank) in accordance with this Section 6, as such
properties and interests are from time to time constituted, are hereinafter
collectively called the "Collateral."  Bank's Lien on the Collateral shall be a
first and prior Lien, subject only to such priority as may be afforded a
Permitted Lien under applicable law.

     In addition to the grant of Liens against the Collateral in favor of Bank,
Guarantors acknowledge the execution and delivery of the Guaranties to Bank in
connection with the Prior Agreement and confirm that the Guaranties apply to the
Obligations to the same extent as they applied to the "Obligations" under and as
defined in the Prior Agreement.  Without limiting the foregoing, each Guarantor
hereby acknowledges and consents to this Loan Agreement and (a) acknowledges
that its obligations under that certain Guaranty dated on or before the date of
this Agreement in favor of Bank includes a guaranty of all of the obligations,
indebtedness and liabilities of Borrower under (i) this Agreement and (ii) the
Notes, (b) represents to Bank that such Guaranty remains in full force and
effect, and (c) agrees that this Agreement and all documents executed in
connection herewith do not operate to reduce or discharge its obligations under
such Guaranty.

7.   Fees.  In addition to the fees payable to Bank as set forth in that certain
fee letter agreement dated May 2, 1996 between Borrower and Bank, Borrower shall
pay to Bank the following commitment fees:

          (i) a commitment fee on the daily average unused amount of Bank's
Advance Term Loan Commitment for the period from and including the date hereof
to and including December 31, 1997, at a rate per annum of one quarter of one
percent (0.25%) whenever the Funded Debt Ratio is less than 2.0:1.0 and three-
eighths of one percent (0.375%) whenever the Funded Debt Ratio is equal to or
greater than 2.0:1.0 (the "Advance Commitment Fee"); and

          (ii) a commitment fee on the daily average unused amount of Bank's
Revolving Loan Commitment for the period from and including the date hereof to
but not including the Revolving Maturity Date, at a rate per annum of one
quarter of one percent (0.25%) whenever the Funded Debt Ratio is less than
2.0:1.0 and three-eighths of one percent (0.375%) whenever the Funded Debt Ratio
is equal to or greater than 2.0:1.0 (the "Revolving Commitment Fee").

Accrued Advance Commitment Fees shall be payable quarterly in arrears on the
first day of each February, May, August and November with respect to the
preceding quarter and on the Advance Maturity Date.  Accrued Revolving
Commitment Fees shall be payable quarterly in arrears on the first day of each
February, May, August and November with respect to the preceding quarter and on
the Revolving Maturity Date.

8.   Prepayments.

(a)  Voluntary Prepayments.  Borrower may at any time and from time to time,
     ---------------------                                                  
     without penalty or premium, prepay any of the Notes, in whole or in part;
     provided, however, that any prepayment of any Eurodollar Loan on any day
     other than an Interest Payment Date must include a payment for all breakage
     costs and funding losses, if any.  Each prepayment of the Advance Term Note
     shall be made on at least one (1) Business Day's notice to Bank and shall
     be in a minimum amount of $100,000 or the unpaid balance of the Advance
     Term Note, whichever is less, and shall be applied to amounts of
     outstanding principal, in reverse order of maturity.

(b)  Mandatory Prepayment of Advance Term Loan.  On or before April 15 of each
     -----------------------------------------                                
     year, beginning April 15, 1997, Borrower shall make a mandatory prepayment
     of the Advance Term Loan in an amount equal to fifty percent (50%) of
     Excess Cash Flow attributable to Borrower's immediately preceding fiscal
     year, calculated on the basis of the annual audited consolidated financial
     statements for such fiscal year delivered pursuant to Section 11(a)(i).
     All such prepayments of the Advance Term Loan shall be accompanied with
     accrued interest to the date of prepayment on the amount so prepaid and
     shall be applied to the installments due thereunder in the inverse order of
     maturity.

AMENDED AND RESTATED LOAN AGREEMENT - Page 26
<PAGE>
 
     Concurrently with the making of any such payment, Borrower shall deliver to
     Bank a certificate in the form of Exhibit D attached hereto demonstrating
     its calculation of the amount required to be paid.

(c)  Mandatory Prepayment of Revolving Loan.  If at any time the then-
     --------------------------------------                          
     outstanding principal balance of the Revolving Loan exceeds the Borrowing
     Base, then Borrower shall immediately pay Bank the amount of such excess as
     a prepayment of principal of the Revolving Loan.

9.   Representations and Warranties.  In order to induce Bank to enter into this
Agreement, Borrower and, to the extent applicable, each Guarantor hereby
represents and warrants to Bank (which representations and warranties will
survive the execution and delivery of this Agreement and the Notes) that:

     organized, validly existing and in good standing under the laws of the
     jurisdiction of its organization and is duly qualified to conduct business
     in all jurisdictions wherein the failure to qualify could result in a
     Material Adverse Effect.

     create and issue the Notes; and Borrower and Guarantors are duly authorized
     and empowered to execute, deliver and perform this Agreement and the other
     Loan Documents to which each is a party; and all action on Borrower's and
     Guarantors' part requisite for the due creation and issuance of the Notes

     Documents upon their creation, issuance, execution and delivery will,
     constitute valid and binding obligations of Borrower and Guarantors, as the
     case may be, enforceable in accordance with their terms (except that
     enforcement may be subject to any applicable bankruptcy, insolvency, or
     similar debtor relief laws now or hereafter in effect and relating to or

     principles of equity).

<PAGE>
 
(e)  No Consent.  The execution, delivery and performance by Borrower and
     ----------                                                          
     Guarantors of the Notes and the other Loan Documents, including this

     obtained by Borrower or such Guarantor as to which such consent may be
     applicable).

(f)  Financial Condition.  The consolidated balance sheets of Borrower and its
     -------------------                                                      
     consolidated Subsidiaries as at December 31, 1995 and the related
     consolidated statements of income and of cash flows for the fiscal year
     ended on such date, reported on by Moore Stephens Simonton, L.L.P., copies
     of which have heretofore been furnished to Bank, present fairly the
     consolidated financial condition of Borrower and its consolidated
     Subsidiaries as at such dates, and the consolidated results of their
     operations and cash flows for the fiscal year then ended.  The two
     unaudited consolidated balance sheets of Borrower and its consolidated
     Subsidiaries as at March 31, 1996 and as at May 31, 1996, and the related
     unaudited consolidated statements of income and of cash flows for the
     three-month and five-month periods ended on such respective dates, copies
     of which have heretofore been filed with the Securities and Exchange
     Commission (in the case of such statements as at March 31, 1996 and for the
     three-month period then ended) and furnished to Bank (in the case of all
     such statements), present fairly the consolidated financial condition of
     Borrower and its consolidated Subsidiaries as at such respective dates, and

     including the related schedules and notes thereto, have been prepared in
     accordance with GAAP applied consistently throughout the periods involved
     (except as approved by such accountants, and as disclosed therein and
     except that the quarterly statements and the statements as at May 31, 1996
     and for the five-month period then ended are unaudited and do not include

     rate or foreign currency swap of exchange transaction, that is not
     reflected in the foregoing statements or in the notes thereto and which, in
     the aggregate, would be material to Borrower and Guarantors, taken as a
     whole, except as set forth on Schedule 9(f).  Since December 31, 1995, no
     change has occurred in the condition, financial or otherwise, of Borrower
     or a Subsidiary thereof that could have a Material Adverse Effect, except
     as set forth in Schedule 9(f).

(g)  Liabilities.  As of the date of this Agreement, neither Borrower nor any
     -----------                                                             
     Guarantor has any material (individually or in the aggregate) liability,
     direct or contingent, except as disclosed in the financial statements
     referenced in Section 9(f) or on Schedule 9(g) attached hereto.  No unusual
     or unduly burdensome restrictions, restraint,

     relative to the business, assets or properties of Borrower or any Guarantor

     financial statements, or as otherwise disclosed to Bank in Schedule 9(h)
     attached hereto, there is no litigation, legal or administrative

     tax returns and reports required to be filed and have paid all taxes,
     assessments, fees and other governmental charges levied upon them or their
     assets, properties or income which are due and payable, including interest
     and penalties, the failure of which to pay could have a Material Adverse
     Effect, except such as are being contested in good faith by appropriate
     proceedings and for which adequate reserves for the payment thereof as
     required by GAAP have been provided and with respect to which levy and
     execution thereon have been stayed and continue to be stayed.

(j)  Titles, Liens.  Borrower and each Guarantor have good and marketable title
     -------------

     circumstance has occurred that, but for the passage of time or the giving
     of notice, or both, would constitute a default under any loan or credit
     agreement, indenture, mortgage, deed of trust, security agreement or other
     agreement or instrument to which Borrower or any Guarantor is a party that
     could in any respect have a Material Adverse Effect.  No Event of Default

     Effect) as a result of any fire, explosion, earthquake, flood, drought,
     windstorm, accident, strike or other labor disturbance, embargo,
     requisition or taking of property or cancellation of contracts, permits or

     business(es), and the payment of transaction expenses in connection with
     such Acquisitions). Borrower will use the proceeds of the Revolving Loan

     any Guarantor is engaged principally or as one of its important activities
     in the business of extending credit for the purpose of purchasing or
     carrying any "margin stock" as defined in Regulation U of the Board of
     Governors of the Federal Reserve System (12 C.F.R. Part 221), or for the

     business, except where the failure to do so does not and will not have a
     Material Adverse Effect. Without limiting the foregoing, Borrower will
     preserve and maintain, and will cause each Subsidiary to preserve and
     maintain, to the extent necessary or desirable in the ordinary conduct of
     its business, its status as an approved provider with all governmental
     authorities (including, without limitation, all agencies administering or
     enforcing health care laws and regulations). Borrower will conduct, and
     will cause each Subsidiary to conduct, its business in an orderly and
     efficient manner in accordance with good business practices.

     Default) shall result or have occurred and be continuing.

     otherwise dispose of any of its assets except for Inventory and obsolete

     ----------------------------                                          
     enter into any transaction with any affiliate, except transactions
     previously disclosed in Borrower's most recent reports on Form 10-KSB and
     Form 10-QSB and otherwise upon terms no less favorable to it than would be
     obtained in a transaction negotiated at arm's length with an unrelated
     third party.

(o)  Acquisitions.  Borrower shall not consummate any Acquisition except in
     ------------                                                          
     accordance with the following conditions: (i) with respect to any single
     Acquisition (or series of related Acquisitions) for which the consideration
     to be paid or given by Borrower and Guarantors exceeds $2,000,000, Borrower
     shall have obtained Bank's written consent to such Acquisition (which may
     be given or withheld by Bank in its discretion); (ii) with respect to any
     single Acquisition (or series of related Acquisitions) for which the
     consideration paid or given by Borrower and Guarantors is less than
     $2,000,000 but for which cumulative consideration paid and to be paid and
     given or to be given is $5,000,000 or more, within the six (6) month period
     then ending, Borrower shall have obtained Bank's prior written consent to
     such Acquisition (which may be given or withheld by Bank in its
     discretion); (iii) Borrower shall notify Bank in writing and with
     reasonable specificity of each such proposed or contemplated Acquisition as
     soon as practical and in any event no later than three (3) Business Days
     after the earlier of (y) the execution and delivery by Borrower or a
     Guarantor, as applicable, of a letter of intent or similar instrument or
     document relating to such Acquisition and (z) the execution and delivery by
     Borrower or a Guarantor, as applicable, of definitive agreements relating
     to such Acquisition (and in the case of either (y) or (z) contemporaneously
     provide Bank with copies thereof); and (iv) if the consideration allocated
     to a covenant or covenants not to compete in connection with any such
     Acquisition is in excess of forty percent (40%) of the dollar amount sum of
     (w) salaries and (x) payments in consideration of a covenant or covenants
     not to compete in both cases agreed to be paid by Borrower or a Guarantor
     (or an affiliate thereof) in connection with such acquisition, then such
     excess shall be subordinated to the Obligations pursuant to subordination
     provisions in form and substance satisfactory to Bank.  For purposes of the
     foregoing sentence, (A) if common stock of Borrower paid or issued (or to
     be paid or issued) to the seller of such stock, security, interest or
     assets, or otherwise issued as part of an Acquisition transaction, is the
     only consideration in such Acquisition transaction, then consideration
     shall not include the value of such common stock, (B) consideration shall
     include obligations incurred or assumed in such acquisition that are
     liabilities on a balance sheet, prepared in accordance with GAAP, of the
     acquiring entity after giving effect to such incurrence or


AMENDED AND RESTATED LOAN AGREEMENT - Page 45
<PAGE>
 
     assumption (but excluding any accounts payable so assumed), (C) without
     limiting the effect of clause (B) above, debt secured by Liens on assets
     acquired in such acquisition, and the principal component of obligations
     under capital leases of assets, which leases are assigned in such
     acquisition (whether or not such assignment requires prior notice or
     consent, or both), in all cases shall be viewed as consideration paid as of
     the closing of such acquisition, (D) payments made or payment obligations
     established in consideration of a covenant not to compete shall be
     considered consideration paid as of the closing of such acquisition, and
     (E) the value of any consideration not expressly denominated in dollars
     shall be the fair market value thereof; provided, however, that nothing in
                                             --------  ------- 
     this sentence shall be construed to limit the prohibitions established by
     Section 12(f).

(p)  Regulation U.  Neither Borrower, any Guarantor, nor any Person acting on
     ------------                                                            
     behalf of Borrower or any of Guarantors has taken or will take any action
     which might cause the loans hereunder or any of the Loan Documents,
     including this Agreement, to violate Regulation U or any other regulation
     of the Board of Governors of the Federal Reserve System or to violate the
     Securities Exchange Act of 1934, as amended, or any rule or regulation
     thereunder, in each case as now in effect or as the same may hereafter be
     in effect.

(q)  Subsidiary Stock.  Except for a sale of all of the capital stock of a
     ----------------                                                     
     Subsidiary, which sale complies with Section 11(n), Borrower shall not
     permit any of its Subsidiaries to, at any time, issue, sell, assign or
     otherwise dispose of (a) any of its capital stock, (b) any securities
     exchangeable for or convertible into or carrying any rights to acquire any
     of its capital stock, or (c) any option, warrant, or other right to acquire
     any of its capital stock, except, in each case, to Borrower or a wholly-
     owned Subsidiary of Borrower.

(r)  Fiscal Year.  Neither Borrower nor any Guarantor shall change its fiscal
     -----------                                                             
     year.

considered an "Event of Default" as that term is used herein:

(a)  Borrower or, to the extent applicable, any Guarantor shall fail to pay when
     due or declared due the principal of, and the interest on any of, the
     Obligations, including the Notes or any fee or any other indebtedness of

     other Security Instruments or any of the other Loan Documents; or

(b)  Any representation or warranty made under this Agreement, or in any
     certificate or statement furnished or made to Bank pursuant hereto, or in

     on which such representation or warranty is


AMENDED AND RESTATED LOAN AGREEMENT - Page 46
<PAGE>
 
     made (or deemed made), or any representation, statement (including
     financial statements), certificate, report or other data furnished or to be
     furnished or made by Borrower or any Guarantor under any of the Loan
     Documents, including this Agreement, proves to have been untrue in any
     material respect, as of the date as of which the facts therein set forth
     were stated or certified; or

(c)  Borrower or a Guarantor (i) shall fail to perform or to observe any
     covenant contained in Sections 11(a), (b), (c), (h), (n), (o), (p), (q), or
     (s) or any provision of Section 12; or (ii) shall fail to perform or to
     observe any covenant or agreement contained herein or in any of the other
     Loan Documents, other than covenants referred to in Sections 13(a), (b) and
     (c) (i) above, and, if such failure is subject to being remedied, such
     failure shall remain unremedied for twenty (20) days after the earlier of
     an officer of such corporation becoming aware thereof or notice thereof
     being given by Bank to Borrower; or

(d)  Default shall be made in respect of (i)(A) any payment obligation
     (regardless of amount) for borrowed money, other than the Notes, for which
     Borrower or any Guarantor is liable (directly, by assumption, as guarantor
     or otherwise) in an aggregate principal amount in excess of $100,000, (B)
     any payment obligation (regardless of amount) secured by any Lien on any

     (C) any lease payment (regardless of amount) relating to a capital lease
     obligation of Borrower or a Guarantor in an aggregate principal amount in
     excess of $100,000, or (ii) any performance obligation (other than a
     payment obligation) with respect to an agreement involving $100,000 or
     more; provided, however, that such default, (i) if a payment default, shall
           --------  -------                                                    
     continue beyond the greater of (A) ten days and (B) the lesser of (x)
     thirty days and (y) the applicable grace period, if any, and (ii) if a non-
     payment default, shall continue beyond the greater of (C) ten days and (D)
     the applicable grace period, if any; provided, further, however, that the
                                          --------  -------  -------          
     foregoing proviso shall apply only if Borrower promptly gives Bank notice
     of such default; or

(e)  Borrower or any Guarantor shall commence a voluntary case or other
     proceedings seeking liquidation, reorganization or other relief with
     respect to itself or its debts under any bankruptcy, insolvency or other
     similar law now or hereafter in effect or seeking an appointment of a
     trustee, receiver, liquidator, custodian or other similar official of it or

AMENDED AND RESTATED LOAN AGREEMENT - Page 47
<PAGE>
 
     respect to it or its debts under any bankruptcy, insolvency or similar law
     now or hereafter in effect or seeking the appointment of a trustee,
     receiver, liquidator, custodian or other similar official of it or any
     substantial part of its property, and such involuntary case or other
     proceeding shall remain undismissed and unstayed for a period of sixty (60)
     days; or an order for relief shall be entered against Borrower or any
     Guarantor under the federal bankruptcy laws as now or hereinafter in
     effect; or

(g)  A final judgment or order for the payment of money in excess of $100,000
     (or judgments or orders for the payment of money aggregating in excess of
     $100,000), exclusive of amounts covered by insurance (as the applicability
     of insurance coverage is determined by Borrower in good faith, but in any
     event excluding from coverage matters as to which the applicable insurance
     company has stated specific grounds for denying, or for reserving its right
     to deny, coverage (excluding any such reservation of rights that is
     customary for such insurance company)) shall be rendered against Borrower
     or any Guarantor and such judgments or orders shall continue unsatisfied or
     unstayed for a period of thirty (30) days; or

(h)  Borrower shall fail to comply in any respect with the mandatory prepayment
     provisions set forth in Section 8;

(i)  A Change of Control shall occur;

(k)  Any Loan Document or any provision thereof shall be alleged by Borrower or
     confirmed by any court of competent jurisdiction to be unenforceable in any
     respect.

     Upon occurrence of any Event of Default specified in Subsections 13(e) and
(f), the Revolving Loan Commitment shall terminate and the entire principal
amount due under the Notes and all interest then accrued thereon, and any other
liabilities of Borrower and any Guarantor hereunder and under the other Loan
Documents, shall become immediately due and payable, all without notice and
without presentment, demand, protest, notice of protest or dishonor, notice of
intent to accelerate, notice of acceleration, or any other notice of any kind,
all of which are hereby expressly waived by Borrower and each Guarantor.  Upon
any other Event of Default that has occurred and is continuing, Bank may by
notice to Borrower terminate the Revolving Loan Commitment and declare the
principal of, and all interest then accrued on, the Notes and any other
liabilities of Borrower and any Guarantor and under the other Loan Documents
hereunder to be forthwith due and payable, whereupon the same shall forthwith
become due and payable without presentment, demand, protest, notice of protest
or dishonor, notice of intent to accelerate, notice of acceleration or any other
notice of any kind, all of which Borrower and each Guarantor hereby expressly
waive, anything contained herein or in the Notes

AMENDED AND RESTATED LOAN AGREEMENT - Page 48
<PAGE>
 
to the contrary notwithstanding. Nothing contained in this Section 13 shall be
construed to limit or amend in any way events of default enumerated in any other
Loan Documents.

     Upon the occurrence and during the continuance of any Event of Default,
Bank is hereby authorized at any time and from time to time, without notice to
Borrower and Guarantors (any such notice being expressly waived by Borrower and
each Guarantor), to set-off and apply any and all deposits (general or special,
time or demand, provisional or final, or otherwise) at any time held and other
indebtedness at any time owing by Bank to or for the credit or the account of
Borrower and Guarantors (other than amounts specifically held in trust for
others) against any and all of the indebtedness of Borrower and Guarantors under
the Notes and the other Loan Documents, including this Agreement, irrespective
of whether or not Bank shall have made any demand under the Loan Documents,
including this Agreement or the Notes and although such indebtedness may be
unmatured.  Any amount set-off by Bank shall be applied against the indebtedness
owed Bank by Borrower or Guarantors pursuant to this Agreement and the Notes.
Bank agrees promptly to notify Borrower and Guarantors after any such set-off
and application, provided that the failure to give such notice shall not affect
the validity of such set-off and application.  The rights of Bank under this
Section 13 are in addition to other rights and remedies (including, without
limitation, other rights of set-off) that Bank may have, including at common
law.

14.   Exercise of Rights.  No failure to exercise, and no delay in exercising, 
on the part of Bank, any right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right. The rights of Bank
hereunder shall be in addition to all other rights provided by law. No
modification or waiver of any provision of the Loan Documents, including this
Agreement, or the Notes, nor consent to departure therefrom, shall be effective
unless in writing, and no such consent or waiver shall extend beyond the
particular case and purpose involved. No notice or demand given in any case
shall constitute a waiver of the right to take other action in the same, similar
or other circumstances without such notice or demand.

15.   Notices.  Any notices or other communications required or permitted to be
given by this Agreement or any other Loan Documents must be given in writing
(which may be by facsimile transmission) and must be personally delivered,
telecopied or mailed by prepaid certified or registered mail to the party to
whom such notice or communication is directed at the address of such party as

such change to the other party pursuant to this Section 15.


AMENDED AND RESTATED LOAN AGREEMENT - Page 49

16.   Expenses.  Borrower and Guarantors, jointly and severally, shall pay (i)
all reasonable and necessary out-of-pocket expenses of Bank, including
reasonable fees and disbursements of special counsel for Bank, in connection
with (A) the negotiation, preparation, execution, filing, recording, re-filing,
recording, re-filing, re-recording, modification, amendment, supplementation and
waiver of any one or more of the Loan Documents, and (B) any default or Event of
Default hereunder, (ii) all reasonable and necessary out-of-pocket expenses of
Bank, including reasonable fees and disbursements of special counsel for Bank,
in connection with the preparation of any participation agreement for a
participant or participants requested by Borrower or any amendment thereof and
(iii) if a default or an Event of Default occurs, all reasonable and necessary
out-of-pocket expenses incurred by Bank, including fees and disbursements of
counsel, in connection with such default or Event of Default, as applicable, and
collection and other enforcement proceedings resulting therefrom.  Borrower
shall indemnify Bank against any transfer taxes, document taxes, and other like
assessments and charges, made by any governmental authority by reason of the
execution and delivery of this Agreement or the Notes.  The obligation of
Borrower and Guarantors set forth in this Section 16 shall survive any
termination of this Agreement, the expiration of the Loans and the payment of
all indebtedness of Borrower to Bank hereunder and under the Notes and the other
Loan Documents.


AMENDED AND RESTATED LOAN AGREEMENT - Page 50

17.   Indemnity; Capital Adequacy.

(a)  Borrower and each Guarantor agree to indemnify and hold harmless Bank and
     its officers, employees, agents, attorneys and representatives (singularly,
     an "Indemnified Party", and collectively, the "Indemnified Parties") from
     and against any loss, cost, liability, damage or expense (including the
     reasonable fees and out-of-pocket expenses of counsel to Bank, including
     all local counsel hired by such counsel) ("Claim") incurred by Bank in
     investigating or preparing for, defending against, or providing evidence,
     producing documents or taking any other action in respect of any commenced
     or threatened litigation, administrative proceeding or investigation under
     any federal securities law, federal or state environmental law, or any
     other statute of any jurisdiction, or any regulation, or at common law or
     otherwise, which is alleged to arise out of or is based upon any acts,
     practices or omissions or alleged acts, practices or omissions of Borrower,
     any of Guarantors or their agents or arises in connection with the duties,
     obligations or performance of the Indemnified Parties in negotiating,
     preparing, executing, accepting, keeping, completing, countersigning,
     issuing, selling, delivering, releasing, assigning, handling, certifying,
     processing or receiving or taking any other action with respect to the Loan
     Documents and all documents, items and materials contemplated thereby, even
     if any of the foregoing arises out of an Indemnified Party's ordinary
     negligence.  The indemnity set forth herein shall be in addition to any
     other obligations or liabilities of Borrower and Guarantors to Bank
     hereunder or at common law or otherwise, and shall survive any termination
     of this Agreement, the expiration of the Loans and the payment of all
     indebtedness of Borrower to Bank hereunder and under the Notes, provided
     that neither Borrower nor any Guarantor shall have any obligation under
     this Section 17 to Bank with respect to any of the foregoing arising out of
     the gross negligence or willful misconduct of Bank or any other Indemnified
     Party.  If any Claim is asserted against any Indemnified Party, the
     Indemnified Party shall endeavor to notify Borrower of such Claim (but
     failure to do so shall not affect the indemnification herein made except to
     the extent of the actual harm caused by such failure).  The Indemnified
     Party shall have the right to employ, at Borrower's expense, counsel of the
     Indemnified Parties' choosing and to control the defense of the Claim.
     Borrower may at its own expense also participate in the defense of any
     Claim.  Each Indemnified Party may at Borrower's expense employ separate
     counsel in connection with any Claim to the extent such Indemnified Party
     believes it reasonably prudent to protect such Indemnified Party.

     The parties intend for the provisions of this Section 17(a) to apply to and
protect each Indemnified Party from the consequences of its own negligence,
whether or not that negligence is the sole, contributing, or concurring cause of
any Claim.

(b)  (i)  In addition to, and without limiting Section5, if after the date of
this Agreement, Bank shall have determined that the adoption of any applicable
law, rule or regulation regarding capital adequacy, or any change therein, or
any change in the interpretation or administration thereof, or compliance by
Bank with

AMENDED AND RESTATED LOAN AGREEMENT - Page 51
<PAGE>
 
any request or directive regarding capital adequacy (whether or not having the
force of law) of any such authority, central bank or comparable agency, has or
would have the effect of reducing the rate of return on Bank's capital as a
consequence of its obligations hereunder to a level below that which Bank could
have achieved but for such adoption, change or compliance (taking into
consideration Bank's policies with respect to capital adequacy) by an amount
deemed by Bank to be material, then from time to time, Borrower shall pay to
Bank such additional amount or amounts as will compensate Bank for such
reduction.

(i)  A certificate of Bank setting forth such amount or amounts as shall be
     necessary to compensate Bank as specified in paragraph(i) above shall be
     delivered as soon as practicable to Borrower and shall be conclusive and
     binding, absent manifest error.  Borrower shall pay Bank the amount shown
     as due on any such certificate within 15 days after Bank delivers such
     certificate.  In preparing such certificate, Bank may employ such
     assumptions and allocations of costs and expenses as it shall in good faith
     deem reasonable and may use any reasonable averaging and attribution
     method.


18.   GOVERNING LAW.  THIS AGREEMENT IS BEING EXECUTED AND DELIVERED, AND IS
INTENDED TO BE PERFORMED, IN DALLAS, DALLAS COUNTY, TEXAS, AND THE APPLICABLE
LAWS OF THE UNITED STATES OF AMERICA AND THE SUBSTANTIVE LAWS OF TEXAS SHALL
GOVERN THE VALIDITY, CONSTRUCTION, ENFORCEMENT AND INTERPRETATION OF THIS
AGREEMENT AND ALL OTHER LOAN DOCUMENTS, UNLESS OTHERWISE SPECIFIED THEREIN.

19.   Invalid Provisions.  If any provision of this Agreement is held to be
illegal, invalid, or unenforceable under present or future laws effective during
the term of this Agreement, then such provisions shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision had never comprised a part of this Agreement, and the
remaining provisions of this Agreement shall remain in full force and effect and
shall not be affected by the illegal, invalid or unenforceable provision or by
its severance from this Agreement.

20.   Maximum Interest Rate.  Regardless of any provisions contained in this
Agreement or in any other Loan Documents, Bank shall never be deemed to have
contracted for or be entitled to receive, collect or apply as interest on the
Notes or otherwise any amount in excess of the maximum rate of interest
permitted to be charged by applicable law, and if Bank ever receives, collects
or applies as interest any such excess, or if acceleration of the maturity of
the Notes or if any prepayment by Borrower results in Borrower having paid any
interest in excess of the maximum rate, such amount which would be excessive
interest shall be applied to the reduction of the unpaid principal balance of
the Notes for which such excess was received,


AMENDED AND RESTATED LOAN AGREEMENT - Page 52
<PAGE>
 
collected or applied, and, if the principal balances of Notes are paid in full,
any remaining excess shall forthwith be paid to Borrower. All sums paid or
agreed to be paid to Bank for the use, forbearance or detention of the
indebtedness evidenced by the Notes and/or this Agreement shall, to the extent
permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term of such indebtedness until payment in full so that the
rate or amount of interest on account of such indebtedness does not exceed the
maximum lawful rate permitted under applicable law. In determining whether or
not the interest paid or payable under any specific contingency exceeds the
maximum rate of interest permitted by law, Borrower and Bank shall, to the
maximum extent permitted under applicable law, (i) characterize any non-
principal payment as an expense, fee or premium, rather than as interest; and
(ii) exclude voluntary prepayments and the effect thereof; and (iii) compare the
total amount of interest contracted for, charged or received with the total
amount of interest which could be contracted for, charged or received throughout
the entire contemplated term of the Notes at the maximum lawful rate under
applicable law.

21.   Amendments.  This Agreement may be amended only by an instrument in 
writing executed by an authorized officer of the party against whom such
amendment is sought to be enforced.

22.   Multiple Counterparts, Etc.  This Agreement may be executed in a number of
identical separate counterparts, each of which for all purposes is to be deemed
an original, but all of which shall constitute, collectively, one agreement.  No
party to this Agreement shall be bound hereby until a counterpart of this
Agreement has been executed by all parties hereto.  References herein to
Sections are references to Sections of this Agreement unless the context
indicates to the contrary.

23.   Conflict.  If any term or provision of this Agreement is inconsistent with
or conflicts with any provision of the other Loan Documents, then the terms or
provisions contained in this Agreement shall be controlling.

24.   Survival.  All covenants, agreements, undertakings, representations and
warranties made in the Loan Documents, including this Agreement and the Notes,
shall survive all closings hereunder and shall not be affected by any
investigation made by any party.

25.   Parties Bound.  This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors, assigns, heirs,
legal representatives and estates; provided, however, that neither Borrower nor
                                   --------  -------                           
any Guarantor may, without the prior written consent of Bank, assign any rights,
powers, duties or obligations hereunder.

26.   Participations.  Bank shall have the right at any time and from time to
time to sell one or more participations in the Notes or any Advance or other
portion thereof; provided, however, that Bank will not at any time retain less
                 --------  -------                                            
than a fifty percent (50%) interest in the indebtedness represented by the
Notes.  To the extent of any such participation the provisions of

AMENDED AND RESTATED LOAN AGREEMENT - Page 53
<PAGE>
 
this Agreement shall inure to the benefit of, and be binding on, each
participant, including, but not limited to, any indemnity from Borrower to Bank.
Borrower shall have no obligation or liability to and no obligation to negotiate
or confer with, any participant, and Borrower shall be entitled to treat Bank as
the sole owner of the Notes without regard to notice or actual knowledge of any
such participation. Upon the occurrence of a default or an Event of Default,
each participant will have and is hereby granted the right to setoff against and
to appropriate and apply from time to time, without prior notice to Borrower or
any other party, any such notice being hereby expressly waived, any and all
deposits (general or special or other indebtedness or claims, direct or
indirect, contingent or otherwise), at any time held or owing by the participant
to or for the credit or account of Borrower against the payment of the Notes and
any other obligations of Borrower hereunder or under the other Loan Documents;
provided, however, that none of the rights granted in this Section 26 shall 
- -------   -------                                                             
apply to any deposits held by any participant constituting trust funds and so
identified to such participant at the time the applicable deposit account is
created. Immediately after such setoff or appropriation by a participant, that
participant shall give Borrower and Bank written notice thereof. However, a
failure to give such notice will not affect the validity of such setoff or
appropriation.

27.  WAIVER OF TRIAL BY JURY.  EACH OF BORROWER AND GUARANTORS WAIVES ANY AND
ALL RIGHTS THAT IT MAY HAVE TO A TRIAL BY JURY ON ANY CLAIM, COUNTERCLAIM OR
OTHER ACTION, OF ANY NATURE WHATSOEVER, RELATING TO OR ARISING OUT OF THIS
AGREEMENT, ANY OF THE OTHER LOAN DOCUMENTS OR THE OBLIGATIONS.  EACH OF BORROWER
AND GUARANTORS ACKNOWLEDGES THAT THE FOREGOING JURY TRIAL WAIVER IS A MATERIAL
INDUCEMENT TO BANK'S ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
AND THAT BANK IS RELYING ON SUCH WAIVER IN ITS FUTURE DEALINGS WITH SUCH
CORPORATION.  EACH SUCH CORPORATION WARRANTS AND REPRESENTS TO BANK THAT SUCH
CORPORATION HAS REVIEWED THE FOREGOING JURY TRIAL WAIVER WITH ITS LEGAL COUNSEL
AND HAS KNOWINGLY AND VOLUNTARILY WAIVED ITS JURY TRIAL RIGHTS FOLLOWING
CONSULTATION WITH SUCH LEGAL COUNSEL.  IN THE EVENT OF LITIGATION, THE FOREGOING
JURY TRIAL WAIVER MY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

28.  DTPA WAIVER.  EACH OF BORROWER AND GUARANTORS HEREBY WAIVES ALL PROVISIONS
OF THE TEXAS DECEPTIVE TRADE PRACTICES CONSUMER PROTECTION ACT (TEX. BUS. & COM.
CODE (S) 17.01 ET SEQ.), OTHER THAN (S) 17.555 THEREOF, AND REPRESENTS AND
WARRANTS TO BANK THAT SUCH CORPORATION (A) HAS ASSETS OF $5,000,000 OR MORE
(EXCEPT THAT ONLY BORROWER AND DHS MANAGEMENT SERVICES, INC. MAKE THE
REPRESENTATION IN THIS CLAUSE (A)), (B) HAS KNOWLEDGE AND EXPERIENCE IN
