                                 PART I

ITEM 1. BUSINESS

Mid  Atlantic  Medical  Services,  Inc.  ("MAMSI")  is  a  holding  company  for
subsidiaries  active in managed health care and other life and health  insurance
related activities.  MAMSI and its subsidiaries (the "Company") have developed a
broad range of managed  health care and related  ancillary  products and deliver
these services  through health  maintenance  organizations  ("HMOs"),  preferred
provider  organizations  ("PPOs"),  a life and health insurance  company, a home
health care company,  a  pharmaceutical  services company and a hospice company.
The Company also has a partnership interest in an outpatient surgery center.


GENERAL DEVELOPMENT OF BUSINESS

MAMSI was  incorporated in Delaware in 1986 to serve as a holding company for MD
- - Individual Practice Association,  Inc. ("M.D. IPA") and Physicians Health Plan
of  Maryland,  Inc.  ("PHP-  MD").  MAMSI made an exchange  offer for all of the
issued and outstanding shares of common stock of M.D. IPA and PHP-MD in 1987.

M.D. IPA, a Federally qualified HMO, was organized as a nonstock  corporation in
1979. M.D. IPA operated as a non-profit  organization until 1985 when it amended
its articles of incorporation and was reorganized into a stock corporation.

PHP-MD, an individual practice  association ("IPA"), was organized as a nonstock
corporation in 1979 to provide  physician and other medical services to M.D. IPA
enrollees.  PHP-MD  operated  as a non-stock  organization  until it amended its
articles of incorporation and was reorganized into a stock corporation in 1984.

MANAGED HEALTH ORGANIZATIONS

MAMSI's primary business is providing access to and managing health care through
its HMOs and its life and health insurance  company.  MAMSI currently offers HMO
coverage through four licensed HMO subsidiaries - M.D. IPA, Optimum Choice, Inc.
("OCI"), Optimum Choice of the Carolinas, Inc. ("OCCI") and Optimum Choice, Inc.
of  Pennsylvania  ("OCIPA") and offers life and health  insurance  through MAMSI
Life and Health Insurance Company ("MAMSI Life").

M.D. IPA became a licensed HMO in Maryland in 1981 and in Virginia in 1985. M.D.
IPA's present  service area (which  includes all geographic  areas where the HMO
has received  regulatory  approval to provide health care services) includes the
entire state of Maryland,  the District of Columbia and most counties and cities
in Virginia  including  the Northern  Virginia,  Richmond/Tidewater  and Roanoke
areas ("HMO Service Area"). In addition to serving governmental entities such as
the Office of Personnel  Management  of the United States  Government  under the
Federal  Employees Health Benefit Plan, M.D. IPA generally  provides coverage to
the larger commercial group market.

OCI, a  non-Federally  qualified HMO, became a licensed HMO in Maryland in 1988,
in Virginia  in 1990,  in  Delaware  in 1993 and in West  Virginia in 1994.  OCI
generally operates within the small business market segment,  which is comprised
of both small and large group  employers  and also covers  Medicaid and Medicare
recipients.  OCI's present commercial service area includes the entire states of
Maryland and  Delaware,  the District of Columbia,  most  counties and cities in
Virginia,  and certain areas of West Virginia.  For the Medicare Program, OCI is
licensed in Northern Virginia, Maryland, Delaware and the District of Columbia.

OCCI, a non-Federally  qualified HMO, became a licensed HMO in North Carolina in
1995 and South Carolina in 1996. OCCI operates in both the small and large group
commercial  market.  OCCI's present service area includes certain areas of North
Carolina and South Carolina.







<PAGE> 5


OCIPA, a  non-Federally  qualified HMO, became a licensed HMO in Pennsylvania in
1996.  OCIPA  operates  in both the  small and large  group  commercial  market.
OCIPA's   present   service  area  includes   five  counties  in   south-central
Pennsylvania.

MAMSI Life, a life and health insurance  company,  is licensed in over 30 states
and actively markets in the states in which MAMSI has licensed HMO's. MAMSI Life
sells group health  insurance as well as a preferred point of service product to
large and small employers and individuals. MAMSI Life also sells group term life
insurance as well as short-term disability insurance.

GENERAL

HMOs  typically  provide or arrange for the provision of  comprehensive  medical
care (including  physician and hospital care) to enrollees for a fixed,  prepaid
premium regardless of the amount of care provided.  Enrollees  generally receive
care from participating primary care physicians ("PCPs") who, as required, refer
enrollees to participating  specialists and hospitals.  HMOs require patients to
utilize participating  physicians and other participating health care providers.
This allows HMOs to  negotiate  favorable  rates and  control  utilization  to a
greater extent than traditional health insurers,  while monitoring and enhancing
the quality of care provided to enrollees.

The goal of an HMO is to combine  quality health care with  management  controls
designed to encourage efficient and economical use of health care services. Such
controls include monitoring physician services,  hospital admissions and lengths
of stay and maximizing the use of non-hospital  based medical services.  Because
an HMO generally  receives fixed monthly premiums from its enrollees  regardless
of the health care  services  provided,  an HMO has an incentive to maintain the
health  of its  enrollees,  while  carefully  monitoring  expenses  through  the
implementation of various cost control strategies and effective management.

MAMSI's HMO provider network is organized as an Individual Practice  Association
("IPA").  Under the IPA model, the HMO contracts with a broadly  dispersed group
of physicians to provide  medical  services to enrollees in the  physicians' own
offices and in hospitals;  the physicians are generally paid on a capitated or a
negotiated fee maximum basis.  Physicians may contract  directly with the HMO or
through a designated organization that, in turn, contracts with the HMO.

MAMSI'S HMO PRODUCTS

MAMSI's  HMOs  offer a range of  benefit  plans  for  providing  health  care to
enrollees.  Generally,  enrollees  arrange for coverage  through their employer.
However,  group  enrollees can convert their coverage to an individual  contract
upon separation  from their employer.  There is no assurance that HMO agreements
with employers will be renewed annually or that, within each employer group, the
HMO will not experience disenrollment by individual enrollees. MAMSI's HMOs also
offer individual coverage to the commercial, Medicaid and Medicare markets.

Under  traditional  HMO  coverage,  the  enrollee  selects  a PCP from the HMO's
provider  network.  All medical care provided to the enrollee must be authorized
and coordinated by the PCP. Generally, the enrollee pays a copayment for all PCP
and  specialist  office  visits and may also be required to pay a copayment  for
hospital  admissions  and  emergency  room  services.   Except  in  emergencies,
enrollees   are   generally   required  to  utilize  only  those   participating
professional and  institutional  health care providers that have contracted with
the IPA (see further  discussion  under "HMO  Arrangements  with  Physician  and
Institutional Providers").

MAMSI's  HMOs,  in  cooperation  with MAMSI Life, a wholly owned  subsidiary  of
MAMSI, also offer  point-of-service  coverage (the "preferred  plan"),  which is
marketed to appeal to the following customers:






<PAGE> 6


  1.  Individuals  who  will  not  consider  a  closed  delivery  system.  These
individuals  prefer the  flexibility of the  traditional  indemnity plan but are
also seeking a lower-cost alternative such as an HMO.

  2. Small to mid-sized  employers who are looking to limit the number of health
care  plan  options.  In this  case,  the HMO  would  seek to be  offered  as an
exclusive health care provider.

In the preferred plan, enrollees have the choice of seeking care from the PCP or
from any physician of their choice (point-of-service  option).  Whenever care is
provided under the  point-of-service  option and the enrollee  visits a provider
outside  of the HMO  network,  MAMSI  Life,  which  underwrites  this  indemnity
benefit,  generally  covers  the  lesser  of 80%  of the  bill  or  100%  of the
established  fee maximum for the service  provided.  The enrollee is responsible
for the remainder of the charge.

Additionally,  MAMSI, through its subsidiaries,  offers hybrid products to large
employer groups. These products offer the ability to tailor employee health care
offerings by varying benefit designs, funding methods and insurance risk. Hybrid
products   generally  compete  in  the  so-called   self-funded   employer  plan
marketplace.  A typical MAMSI hybrid product  combines the use of capitated PCPs
to serve as gatekeepers, employer funding of specialist and institutional claims
on an "as paid"  basis and  MAMSI's  underwriting  of risk of loss on a specific
and/or aggregate stop loss basis.

OCI  offers  HMO  coverage  to  recipients  of  Title  XIX  Medical   Assistance
("Medicaid") in certain  states.  The Medicaid plan operates in a manner similar
to the  traditional  HMO plan. The  participating  states pay a monthly  premium
based upon the age, sex and geographic  location of the recipients for which OCI
provides  comprehensive medical coverage. At December 31, 1997, MAMSI's Medicaid
service area includes certain areas of Virginia,  nine counties in West Virginia
and Mecklenburg and Gaston Counties in North Carolina.

Effective  January 1, 1997,  because of insufficient  reimbursement  rates,  OCI
withdrew from the mandated  Medicaid  Program in the Tidewater  area of Virginia
which reduced the Company's membership by approximately 26,000 members. In July,
1997,  OCI declined to participate  in the State of Maryland  mandated  Medicaid
program,  again due to  insufficient  rates,  which  resulted in OCI's  Maryland
Medicaid  membership of  approximately  38,000 being reassigned to other managed
care  organizations.  Effective  January 1, 1998, OCI withdrew from the Northern
Virginia area due to insufficient  reimbursement  rates. It is anticipated  that
this will reduce OCI's  Virginia  Medicaid  membership  by  approximately  6,000
members.

Under all coverage  options,  enrollees  receive the following  basic  benefits:
primary and specialist physician services;  hospital services such as diagnostic
tests, x-rays,  drugs,  medication,  nursing and maternity services;  outpatient
diagnostic  tests such as  laboratory  tests,  x-rays,  and allergy  testing and
injections.

OCI also offers  health  coverage to Title XVIII  Medicare  recipients.  Under a
contractual   arrangement   with  the  United  States   Health  Care   Financing
Administration  ("HCFA"),  OCI receives a monthly  premium  based upon age, sex,
county of residence and enrollment  status for which OCI provides  comprehensive
medical coverage to those individuals.  Currently, approximately only 11% of the
Medicare  recipients in MAMSI's Medicare service area (which includes  Delaware,
the District of Columbia, several counties in Northern Virginia, and most of the
State of Maryland) are covered through MAMSI or other HMOs. Effective January 1,
1997,  OCI reduced the size of its  Medicare  service  area.  This  reduction in
service area reduced the Company's  Medicare  membership by approximately  5,000
members.  Effective  January 1, 1998,  the Company again reduced the size of its
service area and changed the benefit  structure.  It is  anticipated  that these
changes will further reduce MAMSI's Medicare membership.

The  Company's  total health plan  (managed  care full risk and hybrid,  ASO and
indemnity health  insurance)  membership in the HMOs and MAMSI Life decreased to
approximately  691,000 at December 31, 1997 from 745,000 at December 31, 1996, a
decrease of 7 percent.

The following table sets forth information relevant to MAMSI's HMO and indemnity
health plans as of December 31, 1997:

Employer Groups Served              30,500
Population of Aggregate HMO
  Service Area                  33,500,000
Service Area Penetration               2.1%
Primary Care Physicians              5,200
Specialist Physicians               14,200
Other Affiliated Health
  Care Providers                     7,500
Hospitals and Outpatient
  Facilities                         1,500
Pharmacies                           8,800

A significant  portion of the Company's premium revenue is derived from Federal,
state  and  local  government  agencies  including  governmental  employees  and
Medicaid and Medicare  recipients.  For the years ended December 31, 1997,  1996
and 1995,  approximately 11%, 11% and 7%,  respectively,  of premium revenue was
derived from Federal  government  agencies,  and approximately 25%, 26% and 21%,
respectively,  was derived from state and local  government  agencies located in
the Company's service area.

HMO ARRANGEMENTS WITH PHYSICIAN AND INSTITUTIONAL PROVIDERS

M.D. IPA and OCI  contract  with PHP-MD to provide  physician  services to their
enrollees   while  OCCI  (North   Carolina   and  South   Carolina)   and  OCIPA
(Pennsylvania)   generally  contract  directly  with  providers.  The  HMOs  are
ultimately  responsible  for ensuring that an adequate  number of physicians and
other health care providers are maintained in order to service enrollees.

The  Company  contracts  with many  different  kinds of health  care  providers,
including  primary care and specialist  physicians,  dentists,  social  workers,
psychologists,  physical  therapists  and  podiatrists.  PCPs are paid a monthly
capitation  payment for each enrollee who has chosen that PCP.  This  capitation
payment varies according to the age and sex of the enrollee and according to the
primary care  designation  of the provider  chosen by the enrollee.  The primary
care  designations  on which premiums are based fall into one of two types:  (1)
family  and  general  practice,   pediatrics  and  internal  medicine,  and  (2)
obstetrics and gynecology.

PCPs may  receive,  in  addition  to  capitation  payments,  fees for  specified
procedures   and  an  annual   payment  that  is  based  on  a  Quality   Review
Reconciliation. This payment generally does not exceed 3 percent of their annual
capitation  payments.  The  reconciliation  evaluates the  physician's  practice
performance  as well as quality  issues such as  grievance  rates from  members,
sanctions  by a MAMSI HMO,  and member  transfer  rate.  As part of the  Quality
Review Reconciliation,  the Company provides a quarterly report to each PCP that
compares the physician's  practice performance based on outpatient and inpatient
expenses  to those of his/her  peers and allows the PCP not only to monitor  the
number of referrals  consistent  with  quality  medical  standards,  but also to
evaluate  the  most  cost-effective   consultants  and  facilities  within  each
specialty area.

Prior to July, 1, 1995,  specialist  providers and  participating  non-physician
providers were compensated on a discounted fee maximum basis.  This compensation
was  limited to an  established  maximum  rate that  reflected  the amount  that
similar providers of a similar service would typically charge. Effective July 1,
1995, the Company  modified the method used to compensate  providers and adopted
the Medicare Resource Based Relative Value Scale

methodology of provider reimbursement. This methodology, which applies generally
to specialist health claims,  has resulted in the lowering of some reimbursement
levels,  mainly  those having to do with office and  hospital-based  procedures,
while increasing  payments for many evaluation and management tasks.  Management
believes that this change has allowed the Company to continue to be  competitive
within its marketplace.

The  HMOs  have  contractual   arrangements  with  a  combined  total  of  1,500
facilities, consisting of 300 hospitals and 1,200 non-hospital facilities, as of
December 31, 1997.  These  facilities  are located in the  Company's HMO Service
Area. Contracts with facilities are renewable annually.

HMO ARRANGEMENTS FOR OTHER SERVICES

The HMOs have  contracted with a number of entities to arrange for the provision
of other services:

EMERGENCY CARE - Enrollees may receive urgent care services as an alternative to
hospital  emergency room treatment.  Enrollees can use local urgent care centers
and any hospital emergency room in emergency situations.

HOME HEALTH  CARE - A number of medical  care  providers  are engaged to provide
health  care  services  (such  as  nursing,  pediatric,   neonatal,  orthopedic,
psychiatric,  geriatric,  dialysis treatments,  physical therapy, speech therapy
and respiratory  therapy) at the home of the enrollee.  MAMSI's home health care
subsidiary, HomeCall, Inc. ("HomeCall"), provides these services throughout much
of the Company's service area.

PHARMACEUTICAL  ASSISTANCE  - The Company has  arrangements  with  participating
pharmacies so that an enrollee is only  responsible for the  deductibles  and/or
copayments  that are  indicated on his or her  enrollment  card.  The  Company's
pharmaceutical  company,  HomeCall  Pharmaceutical  Services, Inc. provides home
infusion,  delivery of drugs to  physician  offices and mail order  prescription
services to its members and other payors.

LABORATORY  TESTING - The  Company has an  arrangement  with a  laboratory  that
conducts much of the  laboratory  work required by HMO  providers.  Enrollees in
MAMSI's PPO are similarly referred to this laboratory for testing.

DENTAL - The Company has several dental  products  available  including a dental
indemnity   product   available   from  MAMSI  Life,   subcontracted   capitated
arrangements with a dental HMO, and a discount dental services network through a
dental PPO.

QUALITY ASSESSMENT/IMPROVEMENT AND COST CONTAINMENT

MAMSI conducts a  multidisciplinary  approach to its Quality  Assessment/Quality
Improvement   ("QA/QI")   Program,   utilizing  the  resources  of  all  of  its
subsidiaries  to ensure the provision of quality health care and services to its
HMO enrollees in an appropriate and cost-efficient manner.

MAMSI recognizes the importance of a Continuous Quality  Improvement  Program to
determine and allocate appropriate  resources that will have the greatest impact
for the  members.  The QA/QI  Program is designed to meet and serve the needs of
employers,  members  and  providers  as  well  as  to  monitor  the  timeliness,
appropriateness and effectiveness of services via ongoing and systematic reviews
of key  indicators  and  aspects  of care.  The QA/QI  Program  conducts  member
satisfaction  surveys,  identifies  opportunities  for improvements in providing
care,  adopts  strategies to improve  outcomes and monitors the  improvement  to
report progress.









<PAGE> 9


MAMSI's QA/QI  Committee,  which  operates  under the direction and oversight of
MAMSI's  Board of  Directors,  includes  administrative,  clinical  and provider
representation.  The Committee  evaluates  numerous  quality  related issues and
outcomes measuring overall services provided to enrollees.

In addition,  MAMSI utilizes several cost control and quality review mechanisms.
Provider  applications  are  reviewed  by a  Credentials  Committee  in order to
determine  whether  the  applicant  meets  MAMSI's  criteria,   including  Board
Certification or eligibility.

MAMSI  maintains  a physician  review  process to  determine  whether the needed
levels of medical  service are being provided in a timely and efficient  manner.
The Company  conducts  medical  reviews to monitor the quality of care provided.
The Company  also  monitors the hospital  and  out-of-plan  referrals  issued by
primary care providers.

In most  situations,  prior  authorization  must be obtained  for  non-emergency
hospital  admissions.  Failure to secure prior  authorization  for non-emergency
hospital  admissions  of enrollees  may cause  claims to be denied,  and in some
situations,  providers may be sanctioned.  Prior to admission for  non-emergency
hospital  services,  MAMSI  applies  certain  medical  criteria to authorize the
admission.

After  admission  of an HMO  enrollee,  MAMSI  monitors  the course of  hospital
treatment and coordinates  discharge planning in the hope of preventing unneeded
use of medical  resources.  Although  the  Utilization  Management  staff is not
permitted to interfere with a physician's  medical judgment regarding the course
of treatment,  if the physician decides to extend an enrollee's stay beyond that
authorized,  the physician must provide medical  justification for the necessity
of such proposed action and obtain specific approval.

The HMOs have  established  a grievance  procedure  to respond to  enrollee  and
provider  complaints.  Enrollees  are  encouraged to use this  procedure  before
proceeding  further with a complaint.  Once this  procedure  is  exhausted,  any
unresolved  complaint or grievance may be settled by binding  arbitration rather
than through the courts.  There is a similar  grievance  procedure for physician
complaints.

In 1993, MAMSI invited the National Committee for Quality Assurance ("NCQA"),  a
private, non-profit organization,  to evaluate the Company's methodologies in an
effort to receive NCQA accreditation. NCQA accreditation is a voluntary process.
In the 1993  review,  the Company did not meet certain of NCQA's  criteria  and,
therefore,  did not receive  NCQA  accreditation.  In  response,  MAMSI  adopted
methodologies  and programs designed to respond to concerns and questions raised
in  NCQA's  assessment.  The  Company  requested  the  NCQA to  perform  another
accreditation  review which took place in December of 1996. In May,  1997,  NCQA
informed the Company that its flagship HMOs received one year accreditation. The
Company has  implemented  the Health Plan and Employer Data and  Information Set
("HEDIS") 3.0 which represents a core set of performance  measures  developed by
NCQA to serve the employer as a purchaser.  In  addition,  in October,  1997 the
Maryland  Health  Care  Access  and Cost  Commission  released  the  results  of
Maryland's first ever statewide HMO report card.  MAMSI's Maryland HMOs exceeded
the state wide average in overall  satisfaction,  accessibility and quality.  In
another  survey of member  satisfaction  taken by the U.S.  Office of  Personnel
Management,   federal  employees  expressed   satisfaction  with  the  Company's
federally qualified HMO.

The  Company's  home  health  care  and  home  infusion  subsidiaries  underwent
voluntary  accreditation  review by the Joint  Commission  on  Accreditation  of
Healthcare  Organizations  ("JCAHO") during 1995. Full accreditation  status was
awarded as a result of this process.

COMPETITION AND MARKETING STRATEGY

The  health  care  industry  is  characterized  by  intense  competition.  MAMSI
recognizes the possibility that other entities with greater  resources may enter
into competition with MAMSI






<PAGE> 10


in  the  future  by  either  entering  its  HMO  Service  Area  or by  designing
alternative health care delivery systems.  HMOs compete not only with other HMOs
and managed care  organizations such as provider  sponsored  organizations,  but
also with insurance companies that offer indemnity insurance products.

MAMSI's HMOs compete with  approximately  21 HMOs or other  prepaid  alternative
health care delivery  systems that have a presence in at least one of the cities
or counties in MAMSI's non expansion  service  areas.  The following  table sets
forth  MAMSI's best  estimate of 1997  enrollment  of HMOs  operating in its non
expansion HMO Service Areas. Certain of the HMOs are part of a larger entity and
the enrollees estimated herein include only those in MAMSI's HMO Service Area.

MAMSI's  HMOs compete  with other HMOs and  insurance  companies on the basis of
price, network and range of services offered to enrollees.  PHP-MD competes with
the same entities and with other IPAs for physician  services.  PHP-MD  believes
that  its  capitation  payments  to PCPs  and the fee for  service  payments  to
specialists  are  competitive  with other HMOs.  MAMSI believes that the freedom
IPA-model  HMOs offer  their  enrollees  in  choosing  from a greater  number of
physicians  constitutes a competitive  advantage over group or staff model HMOs.
The ability to retain and attract enrollees will depend, in part, on how present
enrollees assess their benefit packages,  quality of service,  provider network,
rates and the HMOs' responsiveness to enrollee needs.

MAMSI subsidiaries employed  approximately 455 full-time individuals who provide
marketing  services for the Company's  products as of December 31, 1997. MAMSI's
marketing  strategy  includes  identifying  and contacting  employers in its HMO
Service  Area.  In addition,  the Company  employs  prospecting,  telemarketing,
employer group consultation,  referrals by consultants, and the use of a minimum
number of selected  brokers to acquire new accounts.  Since 1994,  the Company's
strategy  has  included  reducing  the use of  brokers  for new  business  while
increasing  its internal  sales  force.  New members  acquired by the  Company's
dedicated  sales force accounted for 48 percent of total large group new members
and 97 percent of total small group new members in 1997.

RISK MANAGEMENT

With the  exception  of  certain  small  group  markets,  OCI uses  underwriting
criteria as a part of its risk management  efforts.  Underwriting is the process
of  analyzing  the risk of  enrolling  employer  groups in order to establish an
appropriate premium rate. Utilizing  underwriting  criteria,  OCI seeks to avoid
contracting  with employers that are likely to experience an actuarially  higher
than  expected need for medical care.  OCI's use of  underwriting  techniques is
restricted in certain  situations by state small group reform  legislation  (see
further discussion under "Government Regulation").

The  Company  maintains  professional,   directors  and  officers,   errors  and
omissions, general liability and property insurance coverage in amounts believed
to be  adequate.  The  Company  requires  participating  hospitals  to  maintain
professional  liability coverage and physicians to have malpractice insurance. A
professional  liability  insurance  policy  provides  coverage in the event that
legal  action is taken  against  any entity as a result of  medical  malpractice
committed by a physician.

In addition,  MAMSI's HMOs reduce the financial impact of catastrophic losses by
maintaining  reinsurance coverage for hospital costs. The reinsurer  indemnifies
80% of the  eligible in and out of service  area  medical  expenses in excess of
$200,000  per  enrollee  per year up to a  lifetime  maximum  of  $2,000,000  in
eligible medical costs.

Through June 30, 1996,  PHP-MD generally placed 5% to 15% of the payments due to
participating  physicians in a Claims Reserve Risk Pool. The Claims Reserve Risk
Pool constitutes a financial  risk-sharing  arrangement  among the participating
physicians  and  PHP-MD.  Amounts  held in the  Claims  Reserve  Risk  Pool were
distributed from time to time by PHP-MD to  participating  physicians if, in the
judgment of PHP-MD's Board of Directors,  PHP-MD's  financial  condition permits
such distribution.  Effective July 1, 1996, Maryland regulations  eliminated the
use of such risk pools by HMOs, therefore,  commencing on that date the majority
of PHP-MD  payments to physicians  are not reduced.  Amounts placed in such risk
pools, in jurisdictions  where it is still  permitted,  are minor. The following
table sets forth  information  regarding the portion of the amount in the Claims
Reserve  Risk Pool that was  distributed  to  participating  physicians  in each
calendar year.

GOVERNMENT REGULATION

MAMSI's HMOs are subject to state and, in some  instances,  Federal  regulation.
Among the areas regulated are: (i) premium rate setting; (ii) benefits provided;
(iii) marketing;  (iv) provider contracts; (v) quality assurance and utilization
review  programs;   (vi)  adherence  to  confidentiality   and  medical  records
requirements;  (vii) enrollment requirements;  and (viii) financial reserves and
other fiscal solvency requirements.









<PAGE> 12


Under  applicable  law,  HMOs  must  generally  provide  services  to  enrollees
substantially  on a fixed,  prepaid basis without regard to the actual degree of
utilization of services.  The Company  generally  fixes the premiums  charged to
employers  for a 12 month period and revises the premium with each  renewal.  In
setting  premiums,  the Company forecasts health care utilization rates based on
the relevant  demographics  and also  considers  competitive  conditions and the
average  number  of  enrollees  in the  employer  group.  In  addition  to these
premiums, enrollees also make copayments to providers as required.

Although premiums established may vary from account to account through composite
rate  factors and  special  treatment  of certain  broad  classes of  enrollees,
Federal regulations generally prohibit Federally qualified HMOs from traditional
experience  rating of accounts on a  retrospective  basis.  Consistent  with the
practices of other Federally qualified HMOs, M.D. IPA, in some situations, bases
the  premiums  it  charges  employers  in part on the  age,  sex and  geographic
location of the enrolled  employees.  M.D.  IPA  believes  that its premiums are
competitive  with other HMOs and health  insurers  and its health  coverage is a
better  value  for  members  because  of the  range of  physician  and  hospital
selection and other benefits provided.

M.D. IPA contracts with the Office of Personnel Management ("OPM") to provide or
arrange health  services  under the Federal  Employees  Health  Benefit  Program
("FEHBP"). The contract with OPM and applicable government regulations establish
premium rating  requirements for the FEHBP. The premiums  established  under the
OPM contract are subject to periodic  review and audit to determine if they were
established in compliance with the community rating and other requirements under
the program.

MAMSI's HMOs must file periodic reports with, and are subject to periodic review
by,  state  regulatory  authorities.  Although  MAMSI's  HMOs are not  regulated
specifically as insurance companies, they must comply with certain provisions of
state  insurance  laws as well as other laws  specifically  enacted to  regulate
HMOs.

MAMSI Life, the Company's insurance subsidiary,  is domiciled in Maryland and is
licensed  in  over 30  states.  MAMSI  Life  is  subject  to  regulation  by the
department of insurance in each state in which it is licensed. These regulations
subject  MAMSI  Life  to  extensive  review  of the  terms,  administration  and
marketing  of  insurance  products  offered  and  minimum  net worth and deposit
requirements.  In addition,  MAMSI Life is required to file periodic reports and
is subject to periodic audits and continuing oversight.  The offering of certain
new insurance products may require the approval of regulatory agencies.

The Company's  home health care  operations  are regulated  principally  in four
areas:  home health care licensing;  certification  for participation in private
insurance and government reimbursement programs; employee licensure and training
requirements;  and Federal occupational safety guidelines.  The Company believes
that  it is  in  compliance  with  all  applicable  regulations,  which  include
possessing  the  required  Certificates  of Need in all  locations in which such
certificates are required.  Additionally,  the Company's infusion and mail order
prescription  businesses  have  obtained the  necessary  licenses and permits to
operate as a full service retail pharmacy.

MAMSI's  customers include employee health benefit plans subject to the Employee
Retirement Income Security Act of 1974 ("ERISA"). To the extent that the Company
has  discretionary  authority in the operation of these plans, the Company could
be considered a plan fiduciary  under ERISA.  Plan  fiduciaries  are barred from
engaging in various prohibited  transactions,  including self-dealing.  They are
also required to conduct the operations of employee  benefit plans in accordance
with each plan's terms.

Due to the  continued  increase in health care costs and the  inability  of many
individuals  to obtain health care  insurance,  numerous  proposals  relating to
health care reform have been made, and  additional  proposals may be introduced,
in the United States  Congress and the  legislatures  of the states in which the
Company operates or may seek to operate.






<PAGE> 13


Recently,  the "Health  Insurance  Portability and  Accountability  Act of 1996,
Public Law 104- 191", commonly called the Kennedy-Kassebaum Bill for its primary
sponsors,  was enacted.  This bill establishes certain Federal  requirements for
large group,  small group, and individual  health benefit plans, and applies not
only to insurers and HMOs but also to ERISA plans.

Kennedy-Kassebaum  is intended to make  coverage  more portable and available by
limiting  pre-existing  condition  requirements;  providing  special  enrollment
periods for  employees who lose other  coverage or whose family status  changes;
prohibiting group plans from denying an individual coverage or charging a higher
premium based on the individual's health status or history;  and by guaranteeing
coverage  availability  and  renewability in certain  circumstances in the small
group  and   individual   markets.   Kennedy-Kassebaum   also   allows  for  the
establishment  of Medical Savings  Accounts;  increases the penalties for health
care fraud and abuse;  and calls for  standardized  health care  information  in
order to reduce administrative costs.

The  effect of  Kennedy-Kassebaum  differs  from  state to  state.  In the group
market,  state laws remain in effect unless they prevent the  application of the
new federal requirements, and in the individual market, state laws govern if the
Health and Human Services Secretary  determines that they provide an "acceptable
alternative  mechanism"  to the  federal  requirement.  This means that in those
states,  like  Maryland,  where state  reforms have already  been  enacted,  the
legislation has little,  if any, effect in the small group market,  but may have
some effect in the individual  market.  In other states,  the  legislation has a
greater effect.

Most of the  provisions of  Kennedy-Kassebaum  took effect on July 1, 1997,  but
some, like the provisions  pertaining to Medical Savings  Accounts,  took effect
earlier and others, like administrative simplification, took effect later.

In recent years,  state  legislatures  in the  Company's  service area have been
active in health care  reform  legislation  targeted at the small group  market,
i.e., usually for groups of 2 to 50 employees. This small group reform is now in
place  in  Maryland,   Virginia,   Delaware  and  North  Carolina,  but  not  in
Pennsylvania,  Washington,  D.C. or West Virginia. Although different in many of
the details,  this type of legislation  generally requires all HMOs and insurers
that offer small  group  coverage  to accept all small  employers  who apply for
coverage  and  to  guarantee   coverage  to  their  employees  seeking  coverage
regardless of their health  status.  The  legislation  also requires  renewal of
these small  group  employer  plans,  limits rate  renewal  increases,  mandates
adjusted  community  rating and eliminates  pre-existing  condition  limitations
either  entirely  or  within a short  period of time,  usually  six  months.  In
addition,  many states have begun to legislate  certain  mandated  benefits like
minimum hospital length of stays and required coverages.

The Company believes that the current political environment in which it operates
will result in continued legislative scrutiny of health care reform and may lead
to  additional  legislative  initiatives.  The  Company is unable to predict the
ultimate  impact on the  Company of any  Federal or state  restructuring  of the
health care delivery or health care  financing  systems,  but such changes could
have a material adverse impact on the operations and financial  condition of the
Company.

The District of  Columbia,  which has not  previously  regulated  HMOs,  enacted
legislation  effective July 1, 1997,  providing for regulatory oversight similar
to that currently  provided by other states. The Company does not anticipate any
significant  negative  impact on its  operations  because of the new  regulatory
oversight in the District of Columbia.

PREFERRED PROVIDER ORGANIZATIONS

MAMSI  offers  PPO  coverage  through  two  subsidiaries:   Alliance  PPO,  Inc.
("Alliance") and Mid Atlantic Psychiatric Services, Inc. ("MAPSI").






<PAGE> 14


PPOs  allow  enrollees  to  receive  care  from   participating   physicians  at
contractually  negotiated  rates.  A PPO is different  from an HMO in that a PPO
does  not  assume  any  financial  risk  from  medical  utilization  nor does it
typically  process claims  payments to providers.  All medical  charges are paid
directly by the payor,  which can be a self-funded  employer,  a health benefits
trust  fund or another  health  insurance  company.  In return for access to the
PPO's  network,  the PPO  charges  the  payor  either a per  employee  rate or a
percentage of the savings of actual claims processed for the services  accessed.
MAMSI's  PPOs  provide  access to  substantially  the same  provider  network as
MAMSI's HMOs.

A PPO operates by being incorporated into an employer's current benefit program,
and offers  some or all of the  following:  access to  physician,  hospital  and
facility  services;  utilization  management and quality  assurance;  and claims
screening and repricing.  The employer  determines the level of the benefits and
any applicable copayments.

Alliance is marketed  primarily to and through  insurance  companies,  insurance
brokers,   consultants,   third  party  administrators  ("TPAs"),   self-insured
employers and union  trusts.  The  advantages  of a TPA  marketing  approach are
minimized  marketing  costs and maximized  market coverage  through  established
TPA-employer  relationships.  Alliance also works  directly  with  employers and
unions  that are  self-insured  and uses  direct  marketing  efforts.  The major
competition comes from other PPOs and individual insurance carriers. At December
31, 1997, Alliance had contracts with approximately  20,900 employer groups that
had access to the entire IPA provider network.

The MAPSI PPO is  comprised  of  providers  specializing  in mental  health  and
substance  abuse  care.   MAPSI's  products  are  marketed   directly  to  TPAs,
self-insured groups, brokers,  indemnity plans, union funds and consultants.  In
addition,  MAPSI  contracts with indemnity  insurers that want to offer groups a
managed  care  mental  health  product.  MAPSI  believes  it  has a  competitive
advantage  with its unique  mental  health  screening  process  that  offers the
employer the benefit of enhanced coordinated  treatment for employees as well as
increased  cost savings.  MAPSI's  major  competitors  include Merit  Behavioral
Health,  Inc.,  Green  Spring  Mental  Health and MCC Inc. At December 31, 1997,
MAPSI  had  a   provider   network   of   approximately   4,000   psychiatrists,
psychologists,  social  workers,  and other  affiliated  licensed  mental health
providers.

Alliance and MAPSI are most often marketed jointly and the prospective purchaser
usually also purchases the MAPSI PPO if the Alliance PPO is purchased. The total
number of lives  covered  under one or both of these PPO products as of December
31, 1997 was approximately 1,006,000.

PPOs are not subject to HMO  regulations by virtue of their  business.  However,
PPOs are subject to certain  state  regulations  governing  the provision of PPO
services such as mandatory state  registration.  It is possible that PPOs may be
subject to increased regulatory oversight in the future.

OTHER PRODUCTS

MAMSI Life currently  underwrites the indemnity  coverage of the HMO's preferred
plans in addition to offering stand-alone indemnity health and dental insurance,
aggregate and specific stop loss insurance for  self-insured  groups,  and group
life,  accidental death and short-term disability policies. In addition, in 1995
MAMSI Life began  providing an  administrative  services only ("ASO") product to
the State of  Maryland.  ASO  business  consists of  allowing  access to MAMSI's
provider network,  without gatekeeper PCPs, and the payment of claims. MAMSI has
no insurance risk on this product.  MAMSI Life holds insurance  licenses in over
30 jurisdictions  including Maryland,  Virginia, the District of Columbia,  West
Virginia,  Delaware  and North  Carolina.  MAMSI Life also  became  licensed  in
Pennsylvania in 1995.








<PAGE> 15


In October,  1994,  MAMSI acquired all of the outstanding  stock of HomeCall and
its wholly owned subsidiary,  FirstCall,  Inc. ("FirstCall"),  for approximately
$10 million, including direct expenses.  HomeCall is a state licensed,  Medicare
certified home health agency. The combined  operations of HomeCall and FirstCall
include 17 branch  locations that serve virtually all of Maryland,  the District
of Columbia, Northern Virginia and the Panhandle area of West Virginia. HomeCall
achieved  full  accreditation  from the Joint  Commission  of  Accreditation  of
Healthcare  Organizations  ("JCAHO"),  following  its survey of all  services in
November, 1995.

Also during 1994, the Company formed a home infusion services company,  HomeCall
Pharmaceutical  Services, Inc. ("HCPS"),  which received its pharmacy license in
1994 and its Federal license from the Drug Enforcement Agency in 1995.

HomeCall,  FirstCall and HCPS provide  services  that are  generally  lower cost
alternatives to  institutional  treatment and care. The Company believes that it
will  provide  better  care to its  members  and  reduce  its  medical  costs by
substituting,  where  medically  appropriate,  in- home  medical  treatment  for
treatment in an institutional setting.

Medical  services  provided by  HomeCall,  FirstCall  and HCPS  include  skilled
nursing,  advanced  nursing  in  support of  infusion  therapy,  maternal/infant
nursing,  physical,  speech  and  occupational  therapy,  medical  social  work,
nutrition  consultation  and home health care aides.  Services  provided by HCPS
include a comprehensive range of in home drug infusion  therapies,  the delivery
of infusion ready drugs for physician office based infusion therapy,  mail order
pharmacy (as described below) and some hospice (as described below).

In April,  1996,  HCPS started a mail-order  pharmacy,  HomeCall  Mail Rx, which
received its pharmacy license and its Federal license in 1996.  HomeCall Mail Rx
fills and delivers  prescription oral medications via common carrier to patients
in their homes. Approximately 12,000 prescriptions are filled each month.

In  November,   1996,  the  Company  started  HomeCall  Hospice  Services,  Inc.
("Hospice"),  which  received  its Maryland  state  license to operate a general
hospice care program on December 3, 1996. Based in Columbia,  Maryland,  Hospice
was  organized  to  address  the  needs of  terminally  ill  patients  and their
families.  This  hospice  program will provide  services to  individuals  in the
comfort of their homes.

Hospice currently serves the Baltimore and Washington,  D.C. metropolitan areas.
It is  the  goal  of  Hospice  to  extend  its  service  delivery  area  to  all
geographical areas served by MAMSI. The addition of hospice services complements
MAMSI's other home care products by having a full range of services available to
its members.

In  addition  to  providing  in-home  medical  care  to the  Company's  members,
HomeCall, FirstCall, Hospice and HCPS will continue to provide services to other
payors, including insurance companies, other HMOs and individuals.

The Company also has an equity interest in an ambulatory  surgery center located
in Rockville,  Maryland.  The surgery  center  conducts  outpatient  surgery and
services to HMO enrollees and other patients.

INVESTMENTS

The  majority  of the  Company's  investments  are held by its  state  regulated
subsidiaries  to  provide  capital  for those  subsidiaries'  operations  and to
satisfy capital,  surplus and deposit requirements of the HMO and insurance laws
of the various  states in which the Company is licensed.  HMO and insurance laws
generally  protect  consumers of insurance  products  with one of the  principal
focuses being on financial  solvency of the companies that underwrite  insurance
risk. These laws and regulations limit the types of investments that can be made
by the regulated  entities with appropriate  investments  being deemed "admitted
assets."  Admitted  assets are those assets that can be used to fulfill  capital
and surplus  requirements.  The Company's  current  investment  policy generally
prohibits  investments  that would be  "non-admitted"  for  statutory  reporting
purposes. The Company has no investments in derivative financial instruments and
has no current intention of owning such investments.

EMPLOYEES

As of December 31, 1997, the Company had a total of 2,639  employees,  including
2,041  full-time  and  598  part-time   employees.   MAMSI's  home  health  care
subsidiaries  employed 733 of these  employees (284 on a full-time basis and 449
on a  part-time  basis).  None  of the  Company's  employees  are  covered  by a
collective  bargaining  agreement and the Company has not  experienced  any work
stoppage  since  its  inception.  The  Company  believes  that  it  has  a  good
relationship with its employees.

ITEM 2. PROPERTIES

To  accommodate  the  Company's  rapid growth,  the Company has purchased  seven
office  buildings  since 1988.  These  buildings  are located in  Rockville  and
Frederick,  Maryland and total  approximately  453,000 square feet of office and
warehouse  space.  The  Company's  headquarters  is  located  at 4  Taft  Court,
Rockville, Maryland 20850.

In addition,  the Company  leases  approximately  163,000  square feet of office
space  and  approximately  5,200  square  feet of  warehouse  space  in  various
locations  within  its  service  areas  to  support  sales  and   administrative
operations.

During 1997, the Company purchased an office building in Frederick,  Maryland in
order to consolidate  existing office space needs and plan for future growth. As
a result,  the  Company  intends to sell and is  actively  marketing  two office
buildings it currently owns.

ITEM 3. LEGAL PROCEEDINGS

The Company has been named as the  defendant in a suit filed by certain  medical
providers  on March  26,  1997 in the  Circuit  Court for Anne  Arundel  County,
Maryland,  which  alleges  that  the  Company  improperly  reduced  payments  to
participating  providers  in the  form  of  "withhold".  It is  the  plaintiffs'
allegation that certain payments should not have been reduced in this manner and
seek unspecified  damages.  This matter has been filed as a class action against
the Company.  On August 18, 1997,  the court stayed  further  proceedings in the
litigation pending  plaintiff's pursuit of arbitration as provided for under the
contract.

The Company is involved in other  various  legal  actions  arising in the normal
course of  business,  some of which seek  substantial  monetary  damages.  After
review, including consultation with legal counsel,  management believes that any
ultimate liability that could arise from these other actions will not materially
affect the Company's consolidated financial position or results of operations.

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

There were no matters  submitted for  shareholder  vote in the fourth quarter of
1997.

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

FORWARD-LOOKING INFORMATION

All forward-looking  information  contained in this Management's  Discussion and
Analysis  of  Financial   Condition  and  Results  of  Operations  is  based  on
management's  current knowledge of factors  affecting MAMSI's business.  MAMSI's
actual  results  may  differ  materially  if these  assumptions  prove  invalid.
Significant risk factors, while not all-inclusive, are:

1. The  possibility  of increasing  price  competition  in the Company's  market
place.

2. The  possibility  of state or Federal  budget  related  mandates  that reduce
premiums for Medicaid or Medicare recipients.

3.  The potential for increased medical expenses due to: - Increased utilization
    by the  Company's  membership.  - Inflation in provider  and  pharmaceutical
    costs.
    - Federal or state  mandates that  increase  benefits or limit the Company's
      oversight ability.

4. The possibility that the Company is not able to expand its service  territory
as  planned  due  to  regulatory   delays  and/or  inability  to  contract  with
appropriate providers.

5. The possibility  that the Company is not able to increase its market share at
the anticipated premium rates.

GENERAL

During the three year period ended  December 31, 1997,  the Company  experienced
rapid expansion through 1996,  followed by a year of relative  stability.  While
membership in certain products  continues to grow, others have shown substantial
decreases  when compared with 1996. The Company has achieved its overall size by
continually  expanding its product lines which include  point-of-service,  small
group, indemnity health, hybrid products, Medicaid and Medicare, group term-life
and through  expansion  into new geographic  markets.  Premium rates during this
time have remained at or near competitive levels for the Company's market place.
During 1997, the Company's  consolidated  operating margin showed a profit after
being slightly  negative in 1996. The Company achieved 1997's results,  in part,
by implementing  product price increases and reducing  membership in products or
effectively   terminating   groups  that  had  the   potential   for   continued
unprofitability.  The  Company  anticipates  that it will  continue  to increase
premium  rates  during  1998.   This  is  a   forward-looking   statement.   See
"Forward-Looking Information" above for a description of those risk factors.

The Company generally receives a fixed premium amount per member per month while
the majority of medical  expenses are  variable  and  significantly  affected by
spontaneous member utilization. Even with managed care controls, unusual medical
conditions  can occur,  such as an outbreak of influenza or a higher than normal
incidence of high cost cases (such as premature births,  complex  surgeries,  or
rare diseases).  As a result, the Company's  quarterly results can be materially
effected and irregular.  However,  over the longer business  cycle,  the Company
believes that its managed care control  systems,  underwriting  procedures (when
allowed) and network of providers will result in continued profitability.

Due to the  continued  escalation of health care costs and the inability of many
individuals  to obtain health care  insurance,  numerous  proposals  relating to
health care reform have been made, and  additional  proposals may be introduced,
in the United States  Congress and the  legislatures  of the states in which the
Company operates or may seek to operate.







<PAGE> 21


Recently,  the "Health  Insurance  Portability and  Accountability  Act of 1996,
Public Law 104- 191", commonly called the Kennedy-Kassebaum Bill for its primary
sponsors,  was enacted.  This bill establishes certain Federal  requirements for
large group,  small group, and individual  health benefit plans, and applies not
only to insurers and HMOs but also to ERISA plans.

Kennedy-Kassebaum  is intended to make  coverage  more portable and available by
limiting  pre-existing  condition  requirements;  providing  special  enrollment
periods for  employees who lose other  coverage or whose family status  changes;
prohibiting group plans from denying an individual coverage or charging a higher
premium based on the individual's health status or history;  and by guaranteeing
coverage  availability  and  renewability in certain  circumstances in the small
group  and   individual   markets.   Kennedy-Kassebaum   also   allows  for  the
establishment  of Medical Savings  Accounts,  increases the penalties for health
care fraud and abuse,  and calls for  standardized  health care  information  in
order to reduce administrative costs.

The  effect of  Kennedy-Kassebaum  differs  from  state to  state.  In the group
market,  state laws remain in effect unless they prevent the  application of the
new federal requirements, and in the individual market, state laws govern if the
Health and Human Services  Secretary  determines that it provides an "acceptable
alternative  mechanism"  to the  federal  requirement.  This means that in those
states like  Maryland,  where state  reforms  have  already  been  enacted,  the
legislation has little,  if any, effect in the small group market,  but may have
some effect on the  individual  market.  In other states,  the  legislation  has
greater effect.

Most of the  provisions of  Kennedy-Kassebaum  took effect on July 1, 1997,  but
some, like the provisions  pertaining to Medical Savings  Accounts,  took effect
earlier and some, like administrative simplification, take effect later.

In recent years,  state  legislatures  in the  Company's  service area have been
active in health care  reform  legislation  targeted at the small group  market,
i.e., usually for groups of 2 to 50 employees. This small group reform is now in
place  in  Maryland,   Virginia,   Delaware  and  North  Carolina,  but  not  in
Pennsylvania,  Washington,  D.C. or West Virginia. Although different in many of
the details,  this type of legislation  generally requires all HMOs and insurers
that offer small  group  coverage  to accept all small  employers  who apply for
coverage  and  to  guarantee   coverage  to  their  employees  seeking  coverage
regardless of their health  status.  The  legislation  also requires  renewal of
these small  group  employer  plans,  limits rate  renewal  increases,  mandates
adjusted  community  rating and eliminates  pre-existing  condition  limitations
either  entirely  or  within a short  period of time,  usually  six  months.  In
addition,  many states have begun to legislate  certain  mandated  benefits like
minimum hospital length of stays and required coverages.

The Company believes that the current political environment in which it operates
will result in continued legislative scrutiny of health care reform and may lead
to  additional  legislative  initiatives.  The  Company is unable to predict the
ultimate  impact upon the Company of any Federal or state  restructuring  of the
health care delivery or health care  financing  systems,  but such changes could
have a material adverse impact on the operations and financial  condition of the
Company.


The District of  Columbia,  which has not  previously  regulated  HMOs,  enacted
legislation effective July 1, 1997 providing for regulatory oversight similar to
that  currently  provided by other states.  The Company does not  anticipate any
significant  negative  impact on its  operations  because of the new  regulatory
oversight in the District of Columbia.

RESULTS OF OPERATIONS

Consolidated  net income (loss) of the Company was $14,489,000 and  $(2,768,000)
in 1997 and 1996,  respectively.  Net earnings (loss) per share was $.31 in 1997
as  compared  to  $(.06)  in  1996.   The  increase  in  earnings  is  primarily
attributable  to a decrease in the medical  loss ratio for  commercial  products
which was slightly  offset by an increase in the  administrative  expense ratio.
The medical loss ratio  decreased  principally  due to increased  efforts by the
Company to control  medical costs through  utilization  review,  enhanced  claim
adjudication,  and  increased  claims audit and claims  reversal  activity.  The
Company  has  priced  its  products  competitively  in  order  to  increase  its
membership base and thereby enhance its strategic  position in its market place.
The Company  currently  has one of the largest HMO and managed care  enrollments
and also the  largest  network of  contract  providers  of  medical  care in its
service area (which  includes the entire  states of Maryland and  Delaware,  the
District of Columbia,  most counties and cities in Virginia and certain areas of
West Virginia, North Carolina and Pennsylvania).

Revenue for the year ended  December  31,  1997  decreased  approximately  $22.1
million or 2.0 percent  over the year ended  December  31,  1996.  A 4.4 percent
decrease in net average HMO and indemnity  enrollment  resulted in a decrease of
approximately  $47.5  million  in health  premium  revenue  while a 2.0  percent
increase in the average monthly premium per enrollee, combined for all products,
resulted in a $20.2 million increase in health premium revenue. The net decrease
in  revenue is mainly  related to the  Company's  withdrawal  from the  Maryland
Medicaid program and from certain areas of the Virginia  Medicaid program due to
inadequate  premiums paid by the states.  Management  believes  that  commercial
health  premiums  should  increase  over the next  twelve  months as the Company
increases its commercial  membership and as new and renewing  groups are charged
higher premium rates due to  legislatively  mandated  benefit  enhancements  and
general price increases initiated by the Company. Effective January 1, 1998, the
Company has modified its Medicare product  offering.  This  modification has the
potential to significantly  reduce the Company's Medicare membership and related
premium  revenue.  This is a  forward-looking  statement.  See "Forward  Looking
Information"  above for a description of the risk factors that may effect health
premiums per member.

The Company has implemented  increased  premium rates across  essentially all of
its  commercial  products  which  began to take  effect  in July,  1996.  As the
Company's  contracts  are  generally  for a one year period,  increased  pricing
cannot be initiated until a contract reaches its renewal date. Therefore,  price
increases  cannot be made  across  the  Company's  membership  at the same time.
Additionally,  the  Company  received  an  approximate  5 percent  premium  rate
increase in its Virginia Medicaid program effective July 1, 1997, an approximate
8 percent premium rate decrease in its North Carolina Medicaid program effective
August 1, 1997,  and an  approximate  2 percent  premium  rate  increase  in its
Medicare  program,  effective  January 1,  1998.  Management  believes  that the
commercial  premium rate  increases may have the effect of slowing the Company's
future  membership growth as compared to membership growth in 1994 through 1996.
In addition,  management  reevaluated premium reimbursement rates with regard to
its  Medicare  and  Medicaid  participation  and reduced or  eliminated  certain
service areas.  Specifically,  effective January 1, 1997, 59 counties and cities
were eliminated from the Company's  Medicare service area.  Effective January 1,
1998,  the Company again reduced its Medicare  service  area,  modified  certain
benefits  and began  charging  an  additional  premium  in certain  areas.  Also
effective  January  1,  1997,  the  Company  discontinued  participation  in the
mandated  portion  of  the  Virginia  Medicaid  program  which  serves  Medicaid
eligibles  in the  Tidewater  area of  Virginia.  In  addition,  the Company has
withdrawn  from the  Maryland  Medicaid  program  due to changes to premium  and
benefit  levels and other  requirements  made by the State of Maryland  after it
obtained  an 1115  waiver and became a mandated  state.  As the  Company was the
largest provider of managed care Medicaid in Maryland,  the Company continued to
provide  services  in 1997 until an orderly  transition  was  accomplished.  The
Company was compensated  during the transition  period at a rate higher than the
mandated  program allows but lower than historical  reimbursement.  In 1996, the
Company became  licensed to serve  portions of the Medicaid  populations in West
Virginia and North Carolina. The Company's

future  membership  growth depends on several  factors such as relative  premium
prices and product availability,  future increases or decreases in the Company's
service area, increased competition in the Company's service area and changes in
state  mandated  enrollment  in  Medicaid  HMO  programs  in which  the  Company
participates.  Enrollment  may also  decrease  if the  Company  determines  that
premium  reimbursement  rates  related to certain  state  Medicaid  programs are
inadequate,   which  would  cause  the  Company  to  voluntarily  withdraw  from
participation.   As  previously  described,   this  determination  was  made  in
connection with the Maryland  Medicaid program and part of the Virginia Medicaid
program.

Service revenue from non-MAMSI  affiliated entities earned by the Company's home
health  care  subsidiaries  contributed  $21.0  million  in  revenue  in 1997 as
compared to $20.5  million in 1996.  This  increase is the result of  increasing
business volume for these subsidiaries,  particularly in the home infusion area,
which is  largely  offset  by an  increasing  relative  percentage  of  business
conducted  for  MAMSI  HMO  and   indemnity   members  which  is  eliminated  in
consolidation.  Revenue from life and short-term disability products contributed
$5.3 million in 1997 as compared to $3.2 million in 1996.

In 1993, MAMSI invited the National Committee for Quality Assurance ("NCQA"),  a
private, non-profit organization,  to evaluate the Company's methodologies in an
effort to receive NCQA accreditation. NCQA accreditation is a voluntary process.
In the 1993  review,  the Company did not meet certain of NCQA's  criteria  and,
therefore,  did not receive  NCQA  accreditation.  In  response,  MAMSI  adopted
methodologies  and programs designed to respond to concerns and questions raised
in  NCQA's  assessment.  The  Company  requested  the  NCQA to  perform  another
accreditation  review which took place in December of 1996. In May,  1997,  NCQA
informed the Company that its flagship HMOs received one year accreditation. The
Company has  implemented  the Health Plan and Employer Data and  Information Set
("HEDIS") 3.0 which represents a core set of performance  measures  developed by
NCQA to serve the employer as a purchaser.  In  addition,  in October,  1997 the
Maryland  Health  Care  Access  and Cost  Commission  released  the  results  of
Maryland's first ever statewide HMO report card.  MAMSI's Maryland HMOs exceeded
the state wide average in overall  satisfaction,  accessibility and quality.  In
another  survey of member  satisfaction  taken by the U.S.  Office of  Personnel
Management,   federal  employees  expressed   satisfaction  with  the  Company's
federally qualified HMO.

Medical  expenses as a  percentage  of health  premium  revenue  ("medical  loss
ratio")  decreased to 89.4 percent for 1997 as compared to 92.4 percent for 1996
and, on a per member per month basis,  medical  expenses  decreased 1.4 percent.
This decrease is due to a combination of factors including continuing efforts by
the Company to implement  product specific cost containment  controls,  expanded
activity  in  specialized  subrogation  areas and claims  review for dual health
coverage,  the adoption of  regionalized  and product  specific fee maximums for
health  services,  and the  identification  and possible  termination of certain
providers  and  specialists  from the  delivery  network  following a continuing
intensified  peer  review  analysis.  In  addition,  during  1997,  the  Company
identified certain claims which had been overpaid and recorded as a reduction of
medical expenses  approximately $12 million relating to claims incurred and paid
in 1996.  The  Company  believes  that it has taken the  appropriate  action and
implemented  appropriate  controls to ensure that future  claims are paid at the
appropriate  amounts although the complexity of paying claims and the increasing
sophistication of providers  requires constant  evaluation of historical payment
patterns which might indicate improper payments.  Additionally,  the Company has
greatly  expanded its initial health  assessments of new Medicare  members after
they have enrolled and has also increased its case management  personnel.  These
initiatives  should  help to control  the  Company's  medical  loss  ratio.  The
statements in the preceding  paragraphs regarding future utilization rates, cost
containment  initiatives,  total  medical  costs and future  increases in health
premiums  per  member  are  forward-looking   statements.  See  "Forward-Looking
Information"  above for a  description  of risk factors that may affect  medical
expenses per member and the medical loss ratio.

The administrative  expense ratio for 1997 increased to 11.7 percent as compared
to 10.7 percent for 1996.  This increase is due primarily to increased  salaries
and  expenses  in  certain  administrative  areas  of  the  Company,   including
utilization management,  claims audit, and customer service departments, as well
as reduced revenue.  Management  believes that the administrative  expense ratio
will remain near the current level over the next year. Management's expectations
concerning the administrative expense ratio are forward-looking  statements. The
administrative  expense  ratio is  affected  by changes in health  premiums  per
member,   development   of  the   Company's   expansion   areas  and   increased
administrative activity related to business volume.

The net margin rate  increased from (.2) percent in 1996 to 1.3 percent in 1997.
This increase is primarily due to the decrease in the medical loss ratio.

THE YEAR ENDED DECEMBER 31, 1996 COMPARED TO THE YEAR ENDED DECEMBER 31, 1995
- -----------------------------------------------------------------------------

RESULTS OF OPERATIONS

Consolidated  net income (loss) of the Company was  $(2,768,000) and $61,124,000
in 1996 and 1995, respectively. Diluted net earnings (loss) per share was $(.06)
in 1996 as compared to $1.28 in 1995.  The  reduction  in earnings is  primarily
attributable to a significant  increase in the medical loss ratio for commercial
products, continuing losses in the Company's Medicare product and lower earnings
from  the  Company's  Medicaid  products.   The  medical  loss  ratio  increased
principally due to increased member utilization.

Revenue for the year ended  December  31, 1996  increased  approximately  $178.8
million or 18.7  percent  over the year ended  December  31,  1995. A 19 percent
increase in net average HMO and indemnity  enrollment resulted in an increase of
approximately $171.5 million in health premium revenue while the average monthly
premium per enrollee,  combined for all  products,  remained  approximately  the
same.

Service revenue from non-MAMSI  affiliated entities earned by the Company's home
health  care  subsidiaries  contributed  $20.5  million  in  revenue  in 1996 as
compared to $18.9  million for 1995.  This  increase is the result of increasing
business volume for these subsidiaries,  particularly in the home infusion area,
which is  largely  offset  by an  increasing  relative  percentage  of  business
conducted  for  MAMSI  HMO  and   indemnity   members  which  is  eliminated  in
consolidation.  Revenue from life and short-term disability products contributed
$3.2 million in 1996 as compared to $1.0 million in 1995.

Medical  expenses as a  percentage  of health  premium  revenue  ("medical  loss
ratio")  increased  to 92.4 percent in 1996 as compared to 81.9 percent for 1995
and, on a per member per month basis,  medical expenses  increased 12.8 percent.
This  significant  increase is due to a combination of factors  including  lower
commercial  premiums  charged due to  competitive  forces,  higher than expected
utilization by commercial members, cost increases due to legislatively  mandated
benefits and extremely high medical expenses  related to the Company's  Medicare
enrollment.

The  administrative  expense ratio for 1996  increased to 10.7 percent from 10.5
percent in 1995.  This  increase is due  primarily  to  increased  salaries  and
expenses in certain  administrative areas of the Company,  including utilization
management  and  customer  service  departments,  as  well as  additional  sales
expenses in new expansion areas in 1996.

Investment  income  increased  $2.4  million or 20 percent  primarily  due to an
increase  of $1.5  million  in  realized  gains on sales  of  marketable  equity
securities.

The net margin rate  decreased from 6.4 percent in 1995 to (.2) percent in 1996.
This decrease is primarily due to the increase in the medical loss ratio.

LIQUIDITY AND CAPITAL RESOURCES

The  Company's  business  is not  capital  intensive  and  the  majority  of the
Company's  expenses are payments to health care providers,  which generally vary
in direct  proportion to the health  premium  revenues  received by the Company.
Although  medical  utilization  rates  vary by  season,  the  payments  for such
expenses  lag behind cash inflow  from  premiums  because of the lag in provider
billing  procedures.  In the past, the Company's cash requirements have been met
principally  from operating  cash flow and it is  anticipated  that this source,
coupled with the Company's  operating line of credit,  will be sufficient in the
future.

Accounts  receivable  increased from $77.0 million at December 31, 1996 to $84.7
million at December 31, 1997.  This $7.7  million  increase is primarily  due to
amounts  due  from the  Federal  government  related  to the  Company's  Federal
Employees Health Benefit Program participation.

Prepaid expenses, advances and other current assets decreased from $32.3 million
at December 31, 1996 to $19.3 million at December 31, 1997,  principally  due to
the receipt of 1996 tax refunds for net  operating  loss  carrybacks.  Statutory
deposits  increased  from $9.1 million at December 31, 1996 to $14.9  million at
December 31, 1997 due to the increase in state  regulatory  deposits  related to
certain of the Company's regulated subsidiaries.

Property  and  equipment  increased  from $45.2  million at December 31, 1996 to
$57.0 million at December 31, 1997 due to the purchase of a new office  building
for  existing  and future  office  space  needs as well as the  replacement  and
upgrade of certain of the Company's computer equipment.

Short-term  investments are marked to market at the end of every quarter and the
resulting  unrealized  gain or loss is  reflected  in the  ending  stockholders'
equity balance. Accordingly,  stockholders' equity at December 31, 1997 reflects
an  unrealized  gain of $.9  million,  net of tax, on the  Company's  short-term
investments.

Medical  claims  payable  decreased  from $118.7 million at December 31, 1996 to
$98.3  million at  December  31, 1997  primarily  due to  decreased  membership,
decreased member utilization and related claims accruals and reversals of claims
previously paid.

Additional paid-in capital decreased from $173.3 million at December 31, 1996 to
$162.9  million  at  December  31,  1997,  principally  due to  activity  in the
Company's stock compensation  trust. This trust is used to provide shares of the
Company's stock to meet its stock option plan obligations.

Deferred tax assets are recognized for deductible temporary differences that, in
management's  opinion, are more likely than not to be realized in the current or
future periods.  The Company's  history of operating  revenue and income growth,
and expectation of future operating  income,  provides strong positive  evidence
that these deferred tax assets will be realized.  A valuation allowance has been
recorded for net operating loss carryforwards  generated by certain subsidiaries
that are not  deductible on a  consolidated  tax return.  Management  intends to
continue to monitor the  realizability of deferred tax assets in light of future
circumstances and assess the reasonableness of the valuation allowance.

The Company  currently has access to total revolving credit  facilities of $24.0
million,  which is used to provide short-term capital resources for routine cash
flow  fluctuations.  At December 31, 1997,  approximately $2.5 million was drawn
against these facilities.

Certain MAMSI  subsidiaries  that are subject to  regulation by state  insurance
departments must notify state regulators  before the payment of any dividends to
MAMSI and, in certain circumstances,  must receive positive affirmation prior to
such  payment.  The  Company  does  not  perceive  these  requirements  to  be a
significant  restriction on the subsidiaries'  ability to pay appropriate future
dividends to the parent company.

The Company does not anticipate  any adverse  impact on future  liquidity due to
medical malpractice issues because the Company carries substantial  professional
liability insurance.

The Company  believes that cash generated from operations along with its current
liquidity and borrowing  capabilities  are adequate for both current and planned
expanded  operations.  Certain capital  expenditures  will be made over the next
year  to  enhance  the  Company's  computer  systems,   and  to  make  necessary
improvements to new and existing administrative offices.

In  1997,  the  Company  began  the  process  of  identifying,   evaluating  and
implementing  changes to computer  programs  necessary  to address the year 2000
issue.  This issue affects  computer systems that have  time-sensitive  programs
that may not properly recognize the year 2000. This could result in major system
failures or  miscalculations.  The Company is currently  addressing its internal
year 2000 issue with  modifications  to existing  programs.  The Company is also
communicating with vendors, financial institutions,  software vendors and others
with which it conducts  business to help them identify and resolve the year 2000
issue.  While the Company has determined  that certain of its software  programs
require  modification,  it does not anticipate any future material impact on its
financial statements.  The total cost associated with the required modifications
and  conversions  is not known at this time,  however,  it is not expected to be
material to the  Company's  results of  operations  or financial  position.  The
statements in the preceding  paragraph regarding future effects of the year 2000
issue is a forward looking statement.  See  "Forward-Looking  Information" for a
description of risk factors.

At its February  1998 meeting,  the Board of Directors  authorized a $20 million
stock repurchase program. The Company may purchase its stock on the open market,
through block trades, or in private  transactions  over the next 12 months.  The
program may be discontinued at any time.

                   Mid Atlantic Medical Services, Inc.
              Notes to Consolidated Financial Statements

NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Mid  Atlantic  Medical  Services,  Inc.  ("MAMSI")  is a holding  company  whose

PRINCIPLES OF CONSOLIDATION

The  consolidated  financial  statements  include the  accounts of MAMSI and its
subsidiaries.  All  significant  intercompany  balances have been  eliminated in
consolidation.











<PAGE> 33


MAJOR CUSTOMERS

The  Company's   operations  are  conducted  within  one  business  segment.   A
significant  portion of the Company's  premium  revenue is derived from federal,
state  and local  government  agencies,  including  governmental  employees  and
Medicaid and Medicare  recipients.  For the years ended December 31, 1997,  1996
and 1995,  approximately 11%, 11% and 7%,  respectively,  of premium revenue was
derived from federal  government  agencies,  and approximately 25%, 26% and 21%,
respectively, was derived from state and local government agencies.

CASH EQUIVALENTS

Floating rate municipal  putable bonds,  which possess an insignificant  risk of
loss from changes in interest rates, that have been held less than three months,
are classified as cash equivalents.

SHORT-TERM INVESTMENTS

Short-term investments,  consisting principally of marketable equity securities,
municipal bonds and tax-free bond funds,  are classified as  available-for-sale.
These  securities are carried at fair market value plus accrued interest and any
unrealized   gains  and  losses  are   reported  as  a  separate   component  of
stockholders'  equity,  net of the  related  tax  effect.  Gains and  losses are
reported in earnings when realized.  Gains and losses on sales of securities are
computed using the specific identification method.

PROPERTY AND EQUIPMENT

Property  and  equipment  is  stated  at  cost  less  accumulated  depreciation.
Depreciation  is provided on a  straight-line  basis over the  estimated  useful
lives of the property and equipment.  Leasehold  improvements are amortized on a
straight-line  basis over the lesser of the life of the  improvement or the term
of the related lease.

STATUTORY DEPOSITS

Statutory deposits, consisting principally of municipal bonds and treasury notes
held in custodial  accounts by state  regulatory  agencies,  are  classified  as
held-to-maturity. These securities are stated at amortized cost.

GOODWILL

The excess of cost over the fair value of net assets of the acquired  company in
the 1994 purchase  transaction  is recorded as goodwill and is classified in the
consolidated  balance  sheets as an other  asset.  Goodwill  is  amortized  on a
straight-line basis over 15 years.

HEALTH PREMIUM

Amounts  charged for health care services are  recognized as premium  revenue in
the month for which enrollees are entitled to receive care.  Included in premium
revenue are amounts due from  customers  that  utilize the  Company's  capitated
primary care physician network, its medical utilization  management services and
other services related to health  management and who self-fund,  generally up to
specified limits, certain elements of medical costs, such as hospitalization and
specialist  physicians.  Premium  revenue  received  in advance is  recorded  as
deferred premium revenue.











<PAGE> 34


FEE AND OTHER

Amounts  charged to third party payors solely for use of the Company's  provider
network and its discounted  fee-for-service rate structure are recognized as fee
revenue. Amounts charged for administrative services only arrangements entailing
only claims payment  services and  utilization of the provider  network  without
utilization  of the Company's  primary care  physician  network and  utilization
management  services and under which the Company  bears no insurance  risk,  are
recognized as fee revenue.

HOME HEALTH SERVICES

Amounts  charged to  patients,  third  party  payors and others for home  health
services  are  recorded  at  net  realizable  amounts,   including   retroactive
adjustments under cost reimbursement agreements with third party payors.

MEDICAL EXPENSE

Medical  expense  consists  principally of medical claims and capitation  costs.
Medical claims include  payments to be made on claims reported as of the balance
sheet date and  estimates  of health care  services  incurred  but not  reported
("IBNR")  to the Company as of the balance  sheet  date.  The IBNR is  estimated
using an expense forecasting model that is based on historical claims incurrence
patterns modified to consider current trends in enrollment,  member  utilization
patterns,  timeliness of claims  submissions  and other  factors.  This estimate
includes  medical costs to be incurred  beyond the premium  paying date that are
contractually required.

Capitation costs represent  monthly fixed fees to  participating  physicians and
other medical providers as retainers for providing continuing medical care.

Medical claims reversals result from the determination that the Company has paid
claims in excess of contractually obligated amounts. Amounts recognized (through
specific  identification  or  estimation)  are recorded at their net  realizable
value as a  reduction  of medical  expense  in the  consolidated  statements  of
operations  and as a reduction  of medical  claims  payable in the  consolidated
balance sheets.

The  Company  believes  that its claims  reserves  are  adequate  to satisfy its
ultimate  claims  liabilities;  however,  the liability as established  may vary
significantly from actual claims amounts, both negatively or positively,  and as
such adjustments are deemed necessary,  they are included in current operations.
Establishment of claims estimates is an inherently  uncertain  process and there
can be no certainty that currently  established  reserves will prove adequate to
cover actual ultimate  expenses.  Subsequent  actual  experience could result in
reserves being too high or too low which could  positively or negatively  impact
the Company's earnings in future periods.

COORDINATION OF BENEFITS

Coordination of benefits ("COB") results from the determination that the Company
has paid for  medical  claims  expenses  for  which an  enrollee  has  duplicate
coverage and for which another insurer is primarily  liable. In the consolidated
statements of operations,  such identified amounts are classified as a reduction
of hospitalization expense and, in the consolidated balance sheets, such amounts
are classified as a reduction of medical claims payable.

INCOME TAXES

The income tax provision  includes Federal and state income taxes both currently
payable and deferred because of differences  between financial reporting and tax
bases of assets  and  liabilities.  Deferred  tax  assets  and  liabilities  are
measured  using the  enacted  tax rates and laws that will be in effect when the
differences are expected to reverse.

EARNINGS (LOSS) PER COMMON SHARE

The Company has adopted  Statement of Financial  Accounting  Standards  No. 128,
"Earnings Per Share", resulting in the restatement of earnings per share for all
prior  periods.  Basic  earnings  per common  share are based upon the  weighted
average  shares  outstanding.  Outstanding  stock  options are treated as common
stock equivalents for purposes of computing  diluted earnings per share.  Shares
held in the Company's Stock  Compensation  Trust (see Note 11) are excluded from
the calculation of basic and diluted earnings per share.

FAIR VALUE OF FINANCIAL INSTRUMENTS

Statement of Financial  Accounting  Standards  No. 107,  "Disclosure  about Fair
Value of Financial  Instruments"  ("Statement No. 107"),  requires disclosure of
fair value information about financial instruments, whether or not recognized in
the balance sheet, for which it is practicable to estimate that value. Statement
No. 107 excludes certain financial instruments and all nonfinancial  instruments
from its disclosure  requirements.  The following  methods and assumptions  were
used by the  Company in  estimating  its fair value  disclosures  for  financial
instruments:

Cash and cash  equivalents - The carrying  amount  reported in the  consolidated
balance sheets approximates fair value.

Short-term investments - Fair values are based on quoted market prices.

Statutory deposits - Fair values are based on quoted market prices.

Short-term borrowings - The carrying amount reported in the consolidated balance
sheets approximates fair value.

ESTIMATES

The  preparation  of the  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  effect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting  period.  Such estimates and assumptions could change in the future as
more  information  becomes  known,  which could impact the amounts  reported and
disclosed herein.

STOCK OPTION PLANS

The Company has elected to follow  Accounting  Principles  Board Opinion No. 25,
"Accounting   for  Stock   Issued  to   Employees"   ("APB   25")  and   related
interpretations  in accounting for its stock option plans. Under APB 25, because
the exercise  price of the Company's  employee  stock options  equals the market
value of the underlying  stock on the date of grant, no compensation  expense is
recognized.

NEW ACCOUNTING STANDARDS

In June, 1997, the Financial Accounting Standards Board issued Statement No. 130
"Reporting  Comprehensive  Income"  ("Statement  130")  and  Statement  No.  131
"Disclosure About Segments of an Enterprise and Related Information" ("Statement
131").  Statement  130  establishes  standards  for  reporting  and  display  of
comprehensive income in a full set of general purpose financial statements,  and
Statement 131 significantly changes the way companies report segment information
in annual financial statements.  Because Statement 131 concerns itself only with
how  supplemental  financial  statement  information  is disclosed in annual and
interim  reports,  the adoption will not have a material impact on the Company's
consolidated financial






<PAGE> 36


statements.  The Company is currently  evaluating the effect of Statement 130 on
its  financial  statements.  Each of these  statements  is effective for periods
beginning after December 15, 1997.

NOTE 2 - INVESTMENTS

Effective January 1, 1994, the Company adopted Statement of Financial Accounting
Standards  No.  115,  "Accounting  for  Certain  Investments  in Debt and Equity
Securities"  ("Statement  No.  115").  Under  this  statement,   securities  are
classified  into  categories  and  are  valued  based  upon  this   designation.
Securities  classified  as  available-for-sale,  which  include  debt and equity
securities  that  the  Company  does not have  the  positive  intent  to hold to
maturity,  are  marked  to market  with the  resulting  unrealized  gain or loss
reflected in stockholders'  equity.  Securities  classified as held-to-maturity,
which are debt  securities  that the  Company has both the  positive  intent and
ability  to hold to  maturity,  are  carried  at  amortized  cost.  The  Company
classifies  its  statutory  deposits as  held-to-maturity  with no effect on the
recorded  value.  All other  investments  are classified as  available-for-sale.
Management  re-evaluates these  designations  annually.  During 1997,  statutory
deposit  investments with an amortized cost of $3,001,000 were released by state
regulatory  agencies and  transferred  to the  Company's  short-term  investment
portfolio. The unrealized gain at the date of transfer was $94,000.

The following is a summary of available-for-sale and held-to-maturity securities
at December 31, 1997:

The  amortized  cost and  estimated  fair  value of debt and  marketable  equity
securities  at December  31, 1997,  by  contractual  maturity,  are shown below.
Actual maturities may differ from contractual  maturities because the issuers of
the  securities  may have the right to  prepay  obligations  without  prepayment
penalties.

</TABLE>

The  noncurrent  portion of notes at December 31, 1997 mature in future years as
follows (in thousands):

  1999                       $60
  2000                        14

The Company has access to total line-of-credit and  letter-of-credit  facilities
of $24 million, which are subject to annual renewal. Borrowings bear interest at
a rate based on either the bank's prime rate or the Federal Funds rate plus .75%
and are secured by certain cash balances and short-term investments. At December
31,  1997,   approximately   $2.25  million  was   outstanding  on  one  of  the
lines-of-credit  at an interest  rate of 7.43% and  approximately  $225,000  was
outstanding in letters-of-credit.

Interest  expense  paid in cash  during  1997,  1996 and 1995 was  approximately
$538,000, $688,000, and $1,541,000, respectively.

NOTE 6 - REINSURANCE

M.D.  IPA, OCI,  OCCI,  OCIPA and MAMSI Life  maintain  reinsurance  coverage to
provide for reimbursement of claims in excess of certain limits. Reinsurance for
health  claims  generally  covers  80% of all  hospital  costs  in  excess  of a
deductible  amount  per  enrollee  per year  (subject  to a  $2,000,000  maximum
lifetime  reinsurance limit per person) but excludes coverage of costs in excess
of certain per diem rates.  The deductible per enrollee was raised from $100,000
to $200,000 effective October 1, 1994. Reinsurance for life and accidental death






<PAGE> 40


claims  generally covers all settlements in excess of $50,000 per person subject
to a $1,000,000  maximum  recovery per person.  Reinsurance  recoveries  for the
years ended  December 31,  1997,  1996 and 1995 were  approximately  $2,045,000,
$2,288,000  and  $128,000,  respectively.  In  the  consolidated  statements  of
operations, reinsurance premiums are shown net of the related recoveries.

NOTE 7 - INCOME TAXES

At December 31, 1997, the Company has net federal  operating loss  carryforwards
of  approximately  $1.3 million for income tax  purposes  that expire in various
years  beginning  in  the  year  2002.   Approximately  $1.2  million  of  these
carryforwards relate to HomeCall,  Inc. operations prior to MAMSI's acquisition.
The  Company's  ability to utilize  these net operating  loss  carryforwards  is
limited.

Deferred  income  taxes  reflect  the net tax effects of  temporary  differences
between the carrying  amounts of assets and liabilities for financial  reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's  deferred tax liabilities and assets are as follows as of December
31:

Total tax deposits made by the Company in 1997, 1996 and 1995 were approximately
$2,461,000, $10,320,000 and $27,266,000, respectively.

NOTE 8 - RISK POOL WITHHOLDINGS

Prior to July 1, 1996,  contracts  with  participating  physicians  allowed  for
withholdings  generally  ranging from 5% to 15% from primary care physicians and
participating  specialists  on  capitation  and  fee-for-service  payments.  The
withheld  amounts  ultimately  paid back to providers is generally less than the
total amount  withheld.  Withheld  liabilities and related medical expenses were
reduced  by  $14,535,000  and  $22,802,000  in 1996 and 1995,  respectively,  to
reflect amounts not returned to providers. Commencing July 1, 1996, the Company,
pursuant  to state  law  changes,  discontinued  withholding  from  payments  in
substantially  all areas of operations.  Amounts  placed in such risk pools,  in
jurisdictions where it is still permitted, were insignificant in 1997.

NOTE 9 - RELATED PARTIES

For the years ended  December 31, 1997,  1996 and 1995,  certain  members of the
Boards  of  Directors  of  MAMSI  and  subsidiary   corporations  who  are  also
participating   physicians  provided  medical  services  to  enrollees  totaling
$6,103,000,   $8,406,000  and   $9,699,000,   respectively,   which   represents
approximately  1% in  1997  and  2% in  all  other  years  of  payments  to  all
physicians.  Board members are remunerated at the same contractual  level as all
other  participating  physicians and are selected by enrollees to render medical
services under the same guidelines as all other participating physicians.

NOTE 10 - EMPLOYEE BENEFIT PLANS

PENSION PLANS

The  Company  has a  defined  contribution  401(k)  savings  plan  covering  all
full-time  employees.  Employees  are allowed to  contribute  up to 10% of their
pre-tax earnings  annually and the Company makes a matching  contribution of 50%
on the first 4% of contributions  made by employees.  Employees vest immediately
in the  employee  contributions  and  ratably  over  six  years  in the  Company
contributions.  During 1997,  1996 and 1995, the Company's  contribution  to the
401(k) plan aggregated $577,000, $540,000 and $433,000, respectively.

Effective  December  31, 1994,  the Company  discontinued  its  non-contributory
defined benefit pension plan (the "Plan"). Benefits earned under the Plan, which
covered  substantially  all  employees,  were  fully  vested at that  date.  The
obligation  to provide  these  benefits  was  satisfied  as of December 31, 1995
through a  combination  of purchases of annuity  contracts,  transfers of vested
funds into the 401(k) plan and cash withdrawals.  The Company  recognized a gain
on  the  curtailment  of the  defined  benefit  pension  plan  of  approximately
$345,000.

In accordance with a personal  service contract  negotiated by the Company,  its
Chairman  is  entitled  to  supplemental  pension  benefits  based upon years of
service and attained salary levels.  Expense recognized related to this plan was
$818,000  and  $1,682,000  for the  years  ended  December  31,  1996 and  1995,
respectively.  During 1997, the service contract was renegotiated, at which time
the supplemental pension benefits package was amended to include a fixed payment
benefit of  $450,000  per year for a fixed term of 15 years.  The  reduction  in
pension expense recognized in 1997 related to this change was approximately $1.1
million.

STOCK OPTION PLANS

In October 1995, the Financial  Accounting  Standards Board issued  Statement of
Financial   Accounting   Standards   No.  123,   "Accounting   for   Stock-Based
Compensation"   ("Statement  123").  Statement  123  prescribes  accounting  and
reporting  standards  for all stock  based  compensation  plans.  Statement  123
requires that the company  either adopt the fair value method of accounting  for
its stock option plans or continue to apply the  existing  accounting  rules but
provide supplemental pro forma disclosures as if the new rules had been adopted.
The Company elected to follow the existing rules and make the required pro forma
disclosures for the first time, in its 1996 consolidated  financial  statements.
Although  Statement 123 first became effective in 1996, it requires that the pro
forma  disclosures  include  the effects of all awards  granted in fiscal  years
beginning  after  December 15, 1994, the majority of which were issued under the
Company's 1995 and 1996 stock option plans.

Pro forma  information  regarding net income and earnings per share are required
by Statement  123, and has been  determined  as if the Company had accounted for
its employee  stock options under the fair value method of that  statement.  The
fair  value  for  these  options  was  estimated  at the date of  grant  using a
Black-Scholes   option   pricing  model  with  the  following   weighted-average
assumptions for 1997, 1996 and 1995,  respectively:  risk-free interest rates of
6.4%,  6.3% and 6.7%;  volatility  factors of the  expected  market price of the
Company's  common stock of .42,  .47 and .53 and a weighted  average life of the
options of 3 years. The Company anticipates that it will declare no dividends.






<PAGE> 43

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded  options which have no vesting  restrictions  and are fully
transferable.  In addition,  option valuation models require the input of highly
subjective  assumptions  including the expected stock price volatility.  Because
the  Company's  employee  stock  options  have   characteristics   significantly
different from those of traded  options,  and because  changes in the subjective
input assumptions can materially effect the fair value estimate, in management's
opinion,  the  existing  models do not  necessarily  provide a  reliable  single
measure of the fair value of its employee stock options.

For purposes of pro forma  disclosures,  the estimated fair value of the options
is amortized to expense over the option's  vesting  period.  The  Company's  pro
forma information follows (in thousands except share amounts):

                                                 1997        1996         1995
                                                ------     -------      -------

Pro forma net income (loss)                     $9,007     $(8,409)     $58,670
Pro forma basic earnings (loss) per share          .19        (.18)        1.28
Pro forma diluted earnings (loss) per share        .19        (.18)        1.23

The effects of  applying  Statement  123 as computed  above are not likely to be
representative  of the pro forma  effects on reported net income in future years
as the above only considers options granted in 1997, 1996 and 1995.

In each year 1990 through 1996, MAMSI  implemented a non-qualified  stock option
plan  whereby  options for the purchase of shares of common stock may be granted
to directors, officers and employees of the Company. Shares authorized under the
plans total 15,500,000. Options under the plans generally vest over a three-year
period and are  exercisable  at 100% of the fair  market  value per share on the
date the options are granted. The Company accounts for these stock option grants
in accordance with APB 25, and, accordingly,  recognizes no compensation expense
for these stock option  grants.  Transactions  relating to the 1990 - 1996 plans
through 1997 are summarized as follows:

The  Company  has an  incentive  compensation  plan  whereby  officers  and  key
employees  receive  bonuses  based  upon the  annual  operating  results  of the
Company.  No  management  bonus was earned in 1997,  1996 or 1995.  In addition,
certain  individuals  receive a cash bonus based upon the achievement of certain
measurable  criteria  other than the annual  operating  results of the  Company.

On April 17, 1995, the  stockholders of MAMSI approved an increase in the number
of authorized shares of common stock from 60,000,000 to 100,000,000.

On August 26, 1996, the Company  established the MAMSI Stock  Compensation Trust
("SCT") to fund its  obligations  arising  from its various  stock  compensation
plans.  MAMSI funded the SCT with 9,130,000  shares of newly issued MAMSI stock.
In exchange,  the SCT has delivered a promissory note to MAMSI for approximately
$129.9 million which  represents the purchase price of the shares.  Amounts owed
by the SCT to  MAMSI  will be  repaid  by  cash  received  by the SCT or will be
forgiven  by MAMSI,  which will  result in the SCT  releasing  shares to satisfy
MAMSI obligations for stock compensation.

For financial reporting  purposes,  the SCT is consolidated with MAMSI. The fair
market  value  of  the  shares  held  by the  SCT is  shown  as a  reduction  to
stockholders'   equity  in  the  Company's   consolidated   balance  sheet.  All
transactions  between the SCT and MAMSI are eliminated.  The difference  between
the cost and fair  value of  common  stock  held in the SCT is  included  in the
consolidated financial statements as additional paid-in capital. At December 31,
1997 and 1996, the SCT held 7,959,375 and 9,020,700  shares of common stock at a
fair market value of approximately $101.5 and $120.7 million, respectively.

Shares held by the SCT are excluded from  weighted  average  shares  outstanding
used in the computation of income or loss per common share.

NOTE 12 - COMMITMENTS AND CONTINGENCIES

The  Company  leases  certain  equipment  and  office  space  under the terms of
noncancellable  operating leases that expire at various dates through 2000. Rent
expense relating to these operating leases approximated  $3,552,000,  $3,316,000
and $2,593,000 in 1997, 1996 and 1995, respectively.

Future minimum lease  commitments under  non-cancelable  operating leases are as
follows for the years ended December 31 (in thousands):

1998                   $ 3,428
1999                     2,687

The Company has been named as the  defendant in a suit filed by certain  medical
providers  on March  26,  1997 in the  Circuit  Court for Anne  Arundel  County,
Maryland,  which  alleges  that  the  Company  improperly  reduced  payments  to
participating  providers  in the  form  of  "withhold".  It is  the  plaintiffs'
allegation that certain payments should not have been reduced in this manner and
seek unspecified  damages.  This matter has been filed as a class action against
the Company.  On August 18, 1997,  the court stayed  further  proceedings in the
litigation pending  plaintiff's pursuit of arbitration as provided for under the
contract. While the Company believes that no significant liability exists, it is
too early to assess the final outcome.

The Company is involved in other  various  legal  actions  arising in the normal
course of  business,  some of which seek  substantial  monetary  damages.  After
review,  including  consultation  with legal  counsel,  management  believes any
ultimate liability that could arise from these other actions will not materially
affect the Company's consolidated financial position or results of operations.

NOTE 13 - STATUTORY REQUIREMENTS

M.D. IPA, OCI, OCCI and OCIPA are subject to insurance department regulations in
the states in which  they are  licensed.  MAMSI  Life is  subject  to  insurance
department regulations in Maryland, its state of domicile.

M.D.  IPA,  OCI,  OCCI,  OCIPA and  MAMSI  Life were in  compliance  with  state
depository  rules at  December  31,  1997 and 1996.  OCCI failed to meet its net
worth  requirement  of $2.5  million and  working  capital  requirement  of $1.6
million at December 31, 1997. In February, 1998, additional capital was provided
so that each of these  requirements  was met.  In  addition,  MAMSI  Life was in
compliance  with the applicable  risk-based  capital  requirements  for life and
health  insurance   companies  at  December  31,  1997  and  1996.  These  MAMSI
subsidiaries must notify state regulators before the payment of any dividends to
MAMSI and, in certain circumstances,  must receive positive affirmation prior to
such payment.

NOTE 14 - RISK CONCENTRATIONS

Financial  instruments  that  potentially  subject  the  Company to credit  risk
consist  primarily of  investments  in marketable  securities  (including  money
market funds, floating rate municipal putable bonds, intermediate term municipal
bonds, and common stocks) and premiums  receivable.  The Company receives advice
through or assigns  direct  management of short-term  investments  in marketable
securities to professional  investment  managers selected for their expertise in
various markets, within guidelines established by the Board of Directors.  These
guidelines  include broad  diversification  of  investments.  Concentrations  of
credit risk and business volume with respect to commercial  premiums  receivable
are generally  limited due to the large number of employer groups comprising the
Company's  customer base. As of December 31, 1997,  approximately 24% of premium
and home health service  receivables were due from federal government  agencies.
The Company performs ongoing credit  evaluations of customers and generally does
not require collateral.

                         Report of Independent Auditors

Board of Directors and Stockholders
Mid Atlantic Medical Services, Inc.


We have audited the  accompanying  consolidated  balance  sheets of Mid Atlantic
Medical  Services,  Inc. and  subsidiaries as of December 31, 1997 and 1996, and
the related  consolidated  statements of  operations,  changes in  stockholders'
equity and cash flows for each of the three years in the period  ended  December
31, 1997. Our audits also included the financial  statement  schedule  listed in
the  Index at Item  14(a).  These  financial  statements  and  schedule  are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements and schedule based on our audits.

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

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material  respects,  the consolidated  financial  position of Mid
Atlantic Medical Services,  Inc. and subsidiaries at December 31, 1997 and 1996,
and the  consolidated  results of their operations and their cash flows for each
of the three years in the period ended  December 31, 1997,  in  conformity  with
generally  accepted  accounting  principles.  Also, in our opinion,  the related
financial  statement  schedule,  when  considered  in relation to the  financial
statements  taken as a whole,  presents  fairly  in all  material  respects  the
information set forth therein.

         SECTION 2.1 PLACE OF MEETINGS.  - Meetings of the  stockholders  may be
held at such place or places within or without the State of Delaware as shall be
fixed by the Board of Directors and stated in the notice of the meeting.

         SECTION 2.2 ANNUAL MEETING. - An annual meeting of stockholders for the

         SECTION 2.3 SPECIAL  MEETINGS.  - Special  meetings of the stockholders
for any  purpose(s)  may be called by the Board of Directors or by the President
stating the purpose(s) of the meeting. No matters, except those set forth in the
notice of special meeting, may be considered at the special meeting.

         SECTION 2.4 NOTICE OF  MEETINGS.  - Notice  stating the time and place,
and in the case of a special meeting the purpose(s)  thereof and by whom called,
shall  be  delivered  to each  stockholder  entitled  to  vote,  not  less  than
twenty-five (25) nor more than sixty (60) days prior to the meeting.  If mailed,
notice shall be directed to each such  stockholder  at his address as it appears
on the  records of the  stockholders  of the  corporation,  unless he shall have

become a stockholder of record after the mailing of such notice and prior to the
meeting,  or to any stockholder who attends such meeting, in person or by proxy,
for purposes other than solely to object to the lack of proper notice, or to any
stockholder who, in person or by proxy, submits a signed waiver of notice either
before or after such meeting.  Notice of any adjourned  meeting of  stockholders
need not be given, unless otherwise required by statute.

         SECTION  2.5  QUORUM  AND  ACTION.  - (a) At any duly held  meeting  of
stockholders,  the  presence in person or by proxy of  stockholders  entitled to
cast a  majority  of the votes  thereat  shall  constitute  a quorum,  except as
otherwise provided by law or the Certificate of Incorporation.

         (b) A majority of the votes cast at a duly held meeting of stockholders
at which a quorum is present (stockholders  represented by proxy shall be deemed
present),  shall be sufficient to take or authorize action upon any matter which
may  properly  come  before the  meeting,  unless a greater  vote,  or voting by
classes,  is required by law or by the Certificate of  Incorporation or by these
By-Laws on any  question,  and except  that in  elections  of  directors,  those
receiving the greatest  number of votes shall be deemed  elected even though not
receiving a majority.

         Notwithstanding  the above,  at all meetings of the  stockholders,  any
vacancy  in the Board of  Directors  by reason of an  increase  in the number of
directors,  the resignation of a director, or for any other cause other than the
removal of a director by the  stockholders,  may be filled only the  affirmative
vote of three-quarters (3/4) of the votes cast at the meeting.

         SECTION 2.6 VOTING. - At each meeting of the stockholders, every holder
of stock then entitled to vote may vote in person or by proxy and, except as may
be otherwise  provided by the Certificate of Incorporation,  shall have one vote
for each share of stock  registered  in his name.  No proxy shall be valid after
eleven  (11) months from the date of its  execution,  unless a longer  period is
provided for in the proxy.  Proxies  shall be exhibited to the  Secretary at the
meeting and filed with the records of the corporation.

         SECTION 2.7  ADJOURNED MEETINGS. - Any duly called meeting
of stockholders may, by announcement thereat, be adjourned to a
designated time and place by the vote of the holders of a


                                                     - 2 -

majority of the shares  present and entitled to vote  thereat,  even though less
than a quorum is so present. If a meeting is adjourned to another time, not more
than thirty days thereafter,  and/or to another place, and if an announcement of
the  adjourned  time  and/or  place  is made at the  meeting,  it  shall  not be
necessary to give notice of the adjourned meeting unless the Board of Directors,
after adjournment, fixes a new record date for the adjourned meeting.

         SECTION 2.8  ACTION BY WRITTEN CONSENT IN LIEU OF MEETING OF
STOCKHOLDERS. - See Section 6.6 of the By-Laws.

         SECTION 2.9 NEW  BUSINESS  AND  NOMINATIONS.  - (a) Only such  business
shall be conducted  as shall have been  brought  before the meeting (i) by or at
the  direction  of the Board of  Directors,  or (ii) by any  stockholder  of the
corporation  who is entitled to vote with respect  thereto and who complies with
the notice procedures set forth in this Section 2.9. For business to be properly
brought  before an annual meeting by a stockholder,  the  stockholder  must have
given timely notice thereof in writing to the Secretary of the  corporation.  To
be timely, a stockholder's notice must be delivered or mailed to and received at
the principal  executive  offices of the  corporation  not less than thirty (30)
days prior to the date of the annual meeting;  provided,  however,  that, in the
event that less than forty (40) days' notice or prior public  disclosure  of the
date of the meeting is given or made to stockholders,  notice by the stockholder
to be timely must be received  not later than the close of business on the tenth

2.9(a). The officer of the corporation or other person presiding over the annual
meeting  shall,  if the facts so warrant,  determine  and declare to the meeting
that business was not properly brought before the meeting in accordance with the
provisions of this Section  2.9(a) and, if he or she should so determine,  he or
she shall so declare to the meeting and any such  business so  determined  to be
not properly brought before the meeting shall not be transacted.  This provision
shall not prevent the  consideration  and approval or  disapproval at the annual
meeting of stockholders of reports of officers,  directors, and committees, but,
in  connection  with such reports,  no new business  shall be acted upon at such
annual meeting unless stated and filed as herein provided.

         (b) At any  special  meeting of the  stockholders,  only such  business
shall be conducted  as shall have been  brought  before the meeting by or at the
direction of the Board of Directors.

         (c) Only persons who are  nominated in accordance  with the  procedures
set  forth  in these  Bylaws  shall  be  eligible  for  election  as  directors.
Nominations of persons for election to the Board of Directors of the corporation
may be made at a meeting of  stockholders  at which  directors are to be elected
only  (i) by or at the  direction  of the  Board  of  Directors,  or (ii) by any
stockholder of the corporation entitled to vote for the election of directors at
the meeting who complies  with the notice  procedures  set forth in this Section
2.9(c).  Such  nominations,  other than those made by or at the direction of the
Board of  Directors,  shall be made by timely notice in writing to the Secretary
of the corporation.  To be timely, a stockholder's  notice shall be delivered or
mailed to and received at the principal executive offices of the corporation not
less than thirty (30) days prior to the date of the meeting; provided,  however,
that, in the event that less than forty (40) days' notice or prior disclosure of
the  date  of the  meeting  is  given  or made to  stockholders,  notice  by the
stockholder  to be  timely  must be so  received  not  later  than the  close of
business on the tenth (10th) day  following  the day on which such notice of the
date of the meeting was mailed or such public disclosure was made.

         Such  stockholder's  notice  shall set forth (i) as to each person whom
such stockholder proposes to nominate for election or re-election as a director,
all  information  relating to such person  that is required to be  disclosed  in
solicitations of proxies for election of directors, or is otherwise required, in
each case pursuant to Regulation 14A under the Securities


                                                     - 4 -

Exchange Act of 1934, as amended  (including  such person's  written  consent to
being named in the proxy  statement as a nominee and to serving as a director if
elected);  and (ii) as to the  stockholder  giving  the  notice (A) the name and
address, as they appear on the corporation's books, of such stockholder, and (B)
the class and  number of shares  of the  corporation's  capital  stock  that are
beneficially  owned  by  such  stockholder.  At  the  request  of the  Board  of
Directors,  any person  nominated  by the Board of  Directors  for election as a
director  shall  furnish to the  Secretary of the  corporation  the  information
required to be set forth in a  stockholder's  notice of nomination that pertains
to the nominee.

         No  person  shall  be  eligible  for  election  as a  director  of  the
corporation  unless  nominated in accordance with the provisions of this Section
2.9(c).  The officer of the corporation or other person presiding at the meeting
shall,  if the facts so warrant,  determine  that a  nomination  was not made in
accordance with such provisions and, if he or she should so determine, he or she
shall  so  declare  to  the  meeting  and  the  defective  nomination  shall  be
disregarded.

                                    DIRECTORS

         SECTION 3.1 NUMBER AND QUALIFICATION.  (a) The first Board of Directors
shall be comprised of  twenty-three  (23)  directors  who shall serve a one-year
term and until their  successors  are elected and  qualified at the first annual
meeting.  Thereafter,  the  number  of  directors  shall be set by the  Board of
Directors;  provided,  however,  that,  except for the first Board, the Board of
Directors  shall be  comprised of no more than twelve (12) and no less than five
(5)  directors,  each of whom shall serve a three-year  staggered term and until
his or her successor is elected and qualified.

         Notwithstanding the above, if the Board of Directors elects a Chairman,
pursuant to Sections 4.1 and 4.3 of the By-Laws, and/or a President, pursuant to
Sections 4.1 and 4.4 of these  ByLaws,  said  Chairman  and/or  President  shall
automatically  become  a  director  of  the  corporation.  The  Chairman  and/or
President  shall remain a director only as long as he or she continues to be the
Chairman and/or President of the Corporation.  As provided for in Section 4.1 of
the By-Laws,  the Chairman and the President  hold office at the pleasure of the
Board, and may be removed and/or replaced at any time, with or without cause.

first  Board of  Directors,  the  successor  directors  shall be  elected by the
stockholders at the first stockholder meeting in members as equally as possible,
into three groups.  Group A directors will have a term of office  expiring after
one year and until the election and  qualification of their successors chosen at
the next annual  shareholders  meeting  ensuing;  Group B directors shall have a
term of  office  expiring  one  year  thereafter  and  until  the  election  and
qualification of their successors; Group C directors shall have a term of office

         (c) Each  successor  to a Group A, B, and C director  shall hold office
until the third annual meeting of the stockholders next succeeding his election,
and until his  successor  is elected and  qualified,  or until his prior  death,
resignation  or  removal;  except  however,  if  additional   directorships  are
established,  the initial term for such  directorships  shall be for one or more
years not greater than three as determined by the Board of Directors in order to
ensure that  approximately  one-third  (1/3) of all the directors are elected at
each annual meeting of the stockholders.

         (d)  Notwithstanding the above, an individual is not qualified to serve
as a  director  if the  individual  is  concurrently  also a  director  of  M.D.
Individual Practice  Association,  Inc., and Physicians Health Plan of Maryland,
Inc.

         SECTION 3.2 POWERS. - The management of all the business,  property and
affairs of the corporation shall be vested in the Board of Directors.  The Board
may  exercise  all of the powers of the  corporation  and do all lawful acts and
things  (including the adoption of such rules and regulations for the conduct of
its meetings, the exercise of its powers, and the management of the corporation,
as it may deem proper),  consistent with the Delaware  General  Corporation law,
the Articles of Incorporation, and these By-Laws, and not thereby conferred upon
or reserved to the stockholders.

         SECTION 3.3  MEETINGS.  - The annual  meeting of the Board of Directors
may be held  without  notice  within four (4) weeks after the annual  meeting of
stockholders. Regular meetings and the time and place of regular meetings of the

meeting at a time more than four (4) weeks after the

annual meeting of the stockholders,  or changes the time or place of any regular
meeting,  notice of such meeting, in accordance with the By-Law requirements for
notice of special meetings,  shall be given to each director who was not present
at the meeting at which such action was taken. Special meetings of the Board may
be called by the Chairman of the Board (if any) or the  President,  and shall be
called at the written request of three of more  directors.  Five (5) days notice
of  special  meetings  shall be given by mail,  or two (2) days  notice if given
personally  or by  telegraph  or cable,  to each  director.  Notice  of  special
meetings  need not state the  purpose(s)  thereof.  A majority of the  Directors
present at the time and place of any regular or special  meeting,  although less
than a quorum,  may adjourn the same from time to time without  notice,  until a
quorum shall be present.  Notice of any special meeting shall not be required to
be given to any  director who shall attend a meeting  without  protesting  prior
thereto  or at its  commencement  the lack of  notice to him,  or who  submits a
signed  waiver of notice,  whether  before or after the  meeting.  Notice of any
adjourned  meeting  shall be required to be given.  Meetings of the Board may be
held at any place within or outside of the State of Delaware.

         A  director  may  attend a meeting  of the Board of  Directors,  or any
committee  thereof,  either  in  person or by means of a  telephone  or  similar
communications  medium which allows all persons  participating in the meeting to
hear and be heard by all others  participating,  and  participation  pursuant to
this subsection shall constitute presence in person at the meeting.

         SECTION  3.4 QUORUM AND  ACTION.  - A majority  of the  directors  then
serving  (but in no event less than  one-third  of the total number of directors
which  the  corporation  would  then  have if  there  were no  vacancies)  shall
constitute a quorum for the transaction of business. At any duly held meeting at
which a quorum is present,  the affirmative  vote of a majority of the directors
present shall be the act of the Board of Directors on any question, except where
the act of a greater number is required by these By-Laws,  by the Certificate of
Incorporation, or by statute.

         SECTION 3.5  ACTION BY WRITTEN CONSENT IN LIEU OF MEETINGS
OF DIRECTORS. - See Section 6.6 of these By-Laws.

         SECTION 3.6  VACANCIES; REMOVAL. - (a)  Any vacancy
occurring in the Board of Directors by reason of an increase in
the number of directors comprising the Board or for any other


                                                     - 7 -


<PAGE>



reason shall be filled by action of a majority of the remaining directors,  even
if less than a quorum,  or by the sole remaining  director.  Vacancies  shall be
filled for the  unexpired  portion of the term of the director  whose vacancy is
being filled.

         (b) Except where the Certificate of Incorporation  provides  otherwise,
contains provisions authorizing cumulative voting or the election of one or more
directors by class or their election by holders of bonds, or requires all action
by stockholders to be by a greater vote, any one or more of the directors may be
removed,  (1) either  for or without  cause,  at any time,  by the  holders of a
majority of the shares then  entitled to vote at an election of directors (a) at
any regular meeting or (b) at any special meeting of the stockholders the notice
of which  announces  that a purpose of such meeting is to seek removal,  or, (2)
for  cause,  by the  affirmative  vote of a  majority  of the  entire  Board  of
Directors at any regular or special  meeting of the Board.  Three (3)  unexcused
absences  within one (1) calendar year from Board of Directors  meetings  and/or
committee  meetings for committees on which such director sits shall  constitute
cause for removal.  The Chairman of the Board,  if a Chairman be elected,  shall
determine  whether an absence is "excused" for purposes of this  paragraph,  but
this  decision  may be  overruled  by an  affirmative  vote of a majority of the
directors at any duly held meeting at which a quorum is present.  If no Chairman
is then serving, the Board members at any duly held meeting at which a quorum is
present shall determine whether an absence is excused.

         SECTION 3.7 COMMITTEES. - The Board of Directors, by resolution adopted
by a majority  of the entire  Board (the  total  number of  directors  which the
Corporation  would  have if there were no  vacancies),  may  designate  from its
members an Executive Committee,  and such other committees as it shall choose to
create,  consisting of one or more directors, with such powers and authority (to
the extent permitted by law) as may be provided in said resolution.

         SECTION 3.8 REMUNERATION.  - (a) Unless otherwise expressly provided by
resolution  adopted by the Board of Directors,  none of the directors  shall, as
such,  receive  any  stated  remuneration  for these  services  but the Board of
Directors  may at any time and from time to time by  resolution  provide  that a
specified sum shall be paid to a director of the Corporation,  either as his/her
annual  remuneration as such director or member of any committee of the Board of
Directors or as  remuneration  for such directors  attendance at each meeting of
the Board of Directors or any such


                                                     - 8 -


<PAGE>



committee. The Board of Directors may also likewise provide that the Corporation
shall  reimburse  each  director for any expenses  paid by him/her on account of
such  attendance  at any meeting.  Nothing in this section shall be construed to
preclude any director  from serving the  Corporation  in any other  capacity and
receiving remuneration thereof.

         (b)  Notwithstanding  the above,  if any director is also a director of
another  corporation  either directly or indirectly owned,  controlled by and/or
under  common   control  of  the   corporation,   such  director  shall  receive
remuneration  as a director  from only one  corporation.  The director  shall be
remunerated  by the  corporation  for which he or she would  receive the greater
remuneration.

vacancies  occurring  among any of the officers shall be filled by the Board for
the unexpired  portion of the  officer's  term and may be filled at a meeting of
the Board  other than its annual  meeting.  Any  officer  may be removed  and/or
replaced  at any time,  with or  without  cause,  by the  affirmative  vote of a
majority (unless the Certificate of Incorporation requires a larger vote) of the
directors  present at a regular  meeting of directors or at a special meeting of
directors called for the purpose.

         SECTION 4.2 OTHER OFFICERS. - The Board may appoint, remove and replace
such other officers,  including  assistant officers and agents, with such powers
and duties as it shall deem necessary. The Board may by resolution authorize the

instruments)  may be exercised on behalf of the  corporation by the President or
such other person as the Board of Directors may authorize.

         1. PURPOSE.  The purpose of this 1993 Non-Qualified Stock Plan ("Plan")
is to advance the interests of Mid Atlantic Medical Services, Inc. ("MAMSI") and
its  subsidiaries  (collectively  referred to as "Company") by  encouraging  and
providing  for the  acquisition  of an equity  interest  in the  Company  by key
employees  through the grant of stock options to purchase Common Stock of MAMSI.
Such Plan will enable the Company to retain the services of key  employees  upon
whose  judgment,  interest,  and special  effort the  successful  conduct of its
operations  is  largely   dependent  and  to  compete   effectively  with  other
enterprises for the services of key employees as may be needed for the continued
improvement of the business.

         2.  STOCK  SUBJECT  TO  PLAN.  The  stock  to  be  subject  to  options
("Options")  under the Plan shall be shares of Mid  Atlantic  Medical  Services,
Inc.  Common  Stock,  par  value  of $.01 per  share  ("Common  Stock"),  either
authorized and unissued or treasury  shares.  The aggregate  number of shares of
Common  Stock for which  Options may be granted  under the Plan shall not exceed
650,000  shares,  subject to  adjustment in  accordance  with the  provisions of
Section  7  hereof.  The  shares  subject  to  the  unexercised  portion  of any
terminated  or expired  Options  under the Plan may again be  available  for new
grants of Options under the Plan.

         3.  ADMINISTRATION.  The Plan shall be  administered  by the  Committee
referred to in Section 4.  Subject to the express  provisions  of the Plan,  the
Committee shall have complete authority,  in its discretion,  to determine those
key employees to whom Options shall be granted.  In making such  determinations,
the Committee  may take into account the nature of the services  rendered by the
respective  key  employees,  their  present and potential  contributions  to the
success  of the  Company,  and  such  other  factors  as the  Committee,  in its
discretion,  shall deem relevant. Subject to the express provisions of the Plan,
the  Committee  shall also have  complete  authority to interpret  the Plan,  to
prescribe,  amend,  and rescind rules and  regulations  relating to the Plan, to
determine the terms and provisions of the respective  Option  agreements  (which
need not be identical),  to determine whether the shares delivered upon exercise
of Options will be treasury shares or will be authorized but previously unissued
shares  and to make all other  determinations  necessary  or  advisable  for the
administration of the Plan; provided,  however,  that no action of the Committee
will be effective  if it  contravenes  or amends this Plan in any  respect.  The
Committee's determinations on the matters referred to in this paragraph shall be
conclusive.

         4. COMMITTEE.  The Committee shall consist of at least three members of
the Board of MAMSI.  No member of the Committee shall be or, during the one year
prior to service as a member,  have been  granted or awarded  equity  securities
pursuant to the Plan or any other plan of the  Company,  except as  permitted by
Rule 16b-3(c) (2) (i). The Committee  shall be appointed,  from time to time, by
the Board of  Directors,  which may, from time to time,  appoint  members of the
Committee  in  substitution  for  members  previously  appointed  and  may  fill
vacancies,  however  caused,  in the  Committee.  A majority of the  Committee's
members shall constitute a quorum. All determinations of the Committee shall


<PAGE>



be made by a majority vote of its members. Any decision or determination reduced
to writing and signed by all of the members shall be fully as effective as if it
had been  made by a  majority  vote at a  meeting  duly  called  and  held.  The
Committee shall also have express  authorization  to hold Committee  Meetings by
conference,  telephone, or similar communication equipment by means of which all
persons  participating in the meeting can hear each other. The Committee may, in
its sole discretion,  delegate all or any portion of its authority, with respect
to Options to be granted to eligible employees who are not officers or directors
of MAMSI, to the President of MAMSI, or any member of the Committee, as it deems
appropriate,  provided that the  Committee  shall  regularly  review all actions
taken pursuant to such delegation of authority.

         5.  ELIGIBILITY.  Options may be granted to such key  employees  of the
Company as the Committee  shall select from time to time. No director who is not
an employee of the Company shall be eligible to receive  Options under the Plan.
An individual may hold more than one Option.

         6. GRANT TERMS AND CONDITIONS OF OPTIONS. Options may be granted at any
time  after the  effective  date of the Plan and from time to time  prior to the
termination  of the  Plan.  Except  as  hereinafter  provided,  Options  granted
pursuant to the Plan shall be subject to the following terms and conditions:

                  a. Price. The purchase price of the shares of stock covered by
all Options granted  pursuant to this Plan shall be no less than the Fair Market
Value of the  Common  Stock of  MAMSI as of the date of grant of the  Option  as
determined by the  Committee.  In the event a public market for the Common Stock
exists,  Fair Market Value shall mean the most recent  closing price  quotation,
or, if none,  the average of the bid and asked prices,  as reported with respect
to  Common  Stock on the most  recent  available  date,  on any  national  stock
exchange on which the Common Stock is then listed,  or if not so listed,  on the
NASDAQ National Market System, or other consolidated  reporting system reporting
trades of the Common  Stock.  If the Common Stock is not so listed,  Fair Market
Value  shall mean the  average of the bid and the asked  prices as quoted by all
market makers in the Common Stock.  In the event that a market for the Company's
Common Stock does not exist, the Committee may determine,  in any case or cases,
that Fair Market Value shall be determined on the basis of the opinion of one or
more  independent and reputable  appraisers  qualified to value companies in the
Company's line of business.

                  b.  Payment Upon  Exercise.  Upon  exercise of an Option,  the
Option Price shall be payable to the Company in cash,  in shares of Common Stock
valued  at the  Fair  Market  Value  thereof  on the  date of  payment,  or in a
combination  of cash and  shares of Common  Stock.  However,  any stock used for
payment must have been held by the Option holder for at least six months.

                  c.  Duration and Exercise of Options.  The Committee may grant
Options for such term as it  determines,  provided  that the term of any Options
shall not exceed 5

                                                         2

<PAGE>



years after the date of the grant.  Each  Option  shall be  exercisable  in such
installments and at such times as designated by the Committee. To the extent not
exercised,  installments  shall  accumulate and be  exercisable,  in whole or in
part, at any time after  becoming  exercisable,  but not later than the date the
Option expires.  Except as hereafter  provided,  all Options granted pursuant to
the Plan shall be  nontransferable,  except by will or the laws of  descent  and
distribution or pursuant to a qualified  domestic  relations order as defined by
the  Internal  Revenue  Code of 1986,  as  amended,  or Title I of the  Employee
Retirement Income Security Act, or the rules thereunder.

                  d. Exercise after  Termination  of Employment.  Subject to the
condition  that no Option  granted  under this Plan shall be  exercisable  after
expiration  of 5 years from the date of the  grant,  or such  shorter  period as
provided in any Option  agreement with an optionee,  the optionee shall have the
following rights upon death, disability or other termination of employment:

     (1) Death. If the optionee's  employment is terminated by death, his estate
or the person  who  acquired  the right to  exercise  such  Option by bequest or
inheritance  from the  optionee  shall  be  entitled,  for a period  of one year
following  the date of his death,  to exercise the Option with respect to all or
any part of the  shares  subject  thereto,  whether or not the Option had become
exercisable at the time of death.

     (2)  Disability.   If  the  optionee's  employment  terminates  because  of
disability  within the meaning of Section  22(e)(3) of the Internal Revenue Code
of 1986, as amended,  the optionee shall have the right for a period of one year
following  the date of such  termination  to exercise the Option with respect to
all or any part of the  shares  subject  thereto,  whether or not the Option had
become exercisable at the time of his disability or termination.

     (3) Other  Reasons.  If the  optionee's  employment is  terminated  for any
reason other than death or disability,  as provided above,  the optionee holding
an Option  under  the Plan  shall  have the  right for a period of three  months
following  such  termination  to exercise  any Option with respect to all or any
part of the  shares  subject  thereto,  to the  extent  the  Option  had  become
exercisable at the time of such termination.

                  e. Other Terms and  Conditions.  The Committee may provide for
such other terms and conditions which shall not be inconsistent  with any of the
terms herein with respect to any Option grant as it shall deem appropriate.  Any
award under the Plan shall be evidenced by an agreement,  which,  subject to the
provisions of the Plan, may contain such terms and conditions as may be approved
by the  Committee,  and shall be executed by an officer on behalf of the Company
and by the  recipient  of the  award.  The  Committee  may  use a  stock  option
agreement  substantially  in the form  attached  to this Plan or any other  form
approved by the Committee.



                                                         3

<PAGE>



                  f.  Restriction  on  Resale.   To  the  extent  the  Committee
determines that any  restrictions on a resale of the shares issued upon exercise
of an Option  is  required  under any rule  promulgated  by the  Securities  and
Exchange  Commission,  the Committee may include in any stock option agreement a
provision  requiring  that the stock  issued on exercise  of the Option  granted
under such agreement  cannot be resold for a specified  period of time after the
date of exercise.

                  g. Effect of Expiration,  Termination or Surrender of Options.
If an Option shall expire or  terminate  unexercised  as to any shares of Common
Stock  covered  thereby,  such shares of Common Stock shall not be deducted from
the number available under Section 2 hereof.

         7.  ADJUSTMENT OF AND CHANGES IN STOCK. In the event that the shares of
Common Stock, as presently constituted, shall be changed into or exchanged for a
different  number  or kind of shares  of stock of MAMSI or of  another  employer
corporation (whether by reason of corporate merger,  consolidation,  acquisition
of property or stock separation, reorganization or liquidation) or if the number
of such  shares of Common  Stock  shall be  changed  through  payment of a stock
dividend,  stock split,  or otherwise,  then there shall be  substituted  for or
added to each share of stock theretofore  appropriated or thereafter  subject or
which may become  subject to an Option  under this Plan,  the number and kind of
such shares of stock into which each outstanding  share of Common Stock shall be
so changed,  or for which each such shares shall be exchanged,  or to which such
shares shall be entitled,  as the case may be. Outstanding Options shall also be
appropriately amended as to price and other terms as may be necessary to reflect
the foregoing events.

         8. CHANGES IN CONTROL.  Upon dissolution or liquidation of the Company,
or upon a  reorganization,  merger or  consolidation in which the Company is not
the surviving corporation, or upon the sale of substantially all of the property
of the  Company  to  another  corporation,  the  Plan  and  the  Options  issued
thereunder shall terminate,  unless  provisions are made in connection with such
transaction  for the  assumption  of  Options  theretofore  granted,  or for the
substitution  for  such  Options  of  new  options  of  the  successor  employer
corporation or a parent or subsidiary thereof, with appropriate adjustment as to
the number and kinds of shares and the per share exercise  prices.  In the event
of such termination, all outstanding Options shall be exercisable in full for at
least 30 days prior to the termination  date whether or not  exercisable  during
such period.  This  acceleration  for vesting will also occur if at least 50% or
more of the voting stock of the Company is sold either through a tender offer or
otherwise  to a party or an  affiliated  group of parties.  For purposes of this
Section 8, Company refers to MAMSI,  MD-Individual  Practice Association,  Inc.,
Optimum Choice,  Inc., and/or Physicians Health Plan of Maryland,  Inc., jointly
and/or separately.

         9. AMENDMENT, MODIFICATION, AND TERMINATION OF THE PLAN. The Committee,
without further approval of the stockholders, but with the approval of the Board
of Directors,  may at any time  terminate  this Plan or any part thereof and may
from time to time amend this Plan as it may deem  advisable.  The termination or
amendment of

                                                         4

<PAGE>



the Plan shall not, without the consent of the employee,  affect such employee's
rights under an award previously granted.

         10. TERM OF THE PLAN.  The Plan shall become  effective on May 1, 1993.
The Plan shall  terminate 5 years after its  effective  date, or on such earlier
date as may be determined by the Board of  Directors.  Termination  of the Plan,
however,  shall not affect the right of the optionees  under Options  previously
granted to them, and all unexpired Options shall continue in force and operation
after termination of the Plan except as they may lapse or be terminated by their
own terms and conditions.

         11.      MISCELLANEOUS PROVISIONS.

     a. Right to Awards.  No  employee or other  person  shall have any claim or
right to be granted any award under the Plan.

     b. Rights as Stockholders.  An optionee shall have no rights as a holder of
Common  Stock by reason of  Options  granted  under the Plan,  unless  and until
certificates for shares of Common Stock are issued to the optionee.

     c. No  Assurance  of  Employment.  Neither  the Plan nor any  action  taken
thereunder shall be construed as giving any employee any right to be retained in
the employ of the Company or any subsidiary.

     d. Costs and Expenses. All costs and expenses incurred in administering the
Plan shall be borne by the Company.

     e.  Unfunded  Plan.  The Plan shall be unfunded.  The Company  shall not be
required  to  establish  any  special  or  separate  fund nor to make any  other
segregation of assets to assure the payment of any award under the Plan.

     f. Withholding  Taxes. Each optionee shall arrange with the Company a means
of paying any federal,  state,  local or foreign  withholding tax as required by
law upon the exercise of an Option under the Plan.  Amounts to which the Company
is entitled  pursuant to  Paragraph  11(f) may be paid,  at the  election of the
optionee,  either  (i) in cash  withheld  from the  employee's  salary  or other
compensation payable by the Company, (ii) with the approval of the Committee, in
shares of Common Stock  otherwise  issuable to the employee  upon exercise of an
Option that have a Fair  Market  Value on the date on which the amount of tax to
be withheld is determined ("Tax Date") equal to the amount of tax the Company is
entitled  to  withhold,  or (iii) cash paid to the Company by the  optionee.  An
optionee's  election to have withheld  shares of Common Stock that are otherwise
issuable  shall  be in  writing,  shall  be  irrevocable  upon  approval  by the
Committee,  and shall be  delivered  to the  Company  prior to the Tax Date with
respect to the exercise of an Option.



                                                         5

<PAGE>


     g.  Assignment or Transfer.  Options or other awards granted under the Plan
or any rights or interests  therein shall not be assignable or  transferable  by
the recipient  thereof except by will or the laws of descent and distribution or
pursuant  to a qualified  domestic  relations  order as defined by the  Internal
Revenue Code of 1986, as amended,  or Title I of the Employee  Retirement Income
Security Act, or the rules thereunder.

     h. Investment Representation.  The Committee may, in its discretion, demand
that any employee  awarded an Option shall  deliver to the Committee at the time
of exercise of such  Option a written  representation  that the shares of Common
Stock to be acquired upon exercise are to be acquired for investment and not for
resale or with a view to the distribution thereof. Upon such demand, delivery of
such written  representation by the employee prior to the delivery of any shares
of Common  Stock  pursuant to the  exercise  of his Option  shall be a condition
precedent to the employee's  right to purchase or otherwise  acquire such shares
of Common Stock by such exercise. The Company is not legally obligated hereunder
if fulfillment of its obligations  under the Plan would violate federal or state
securities laws.

     i. Nature of Benefits.  Awards under the Plan,  and payments  made pursuant
thereto,  are not a part  of  salary  or  base  compensation,  and  will  not be
considered in  determining  an employee's  benefits or  contributions  under any
retirement plan.

     j.  Registration.  Management is directed to register stock issued pursuant
to this plan with the Securities and Exchange Commission.

Re:      1993 Non-Qualified Stock Option Plan

Dear ________:

         Mid Atlantic Medical Services, Inc. (the "Corporation") has adopted the
1993  Non-Qualified  Stock Option Plan (the "Plan") which provides for the grant
of options to purchase  shares of the  Corporation's  common stock  ("stock") to
certain key employees of the  Corporation  and its  subsidiaries.  Since you are
considered a key employee,  and since the Corporation desires you to remain, you
are  being  provided  with a means to  acquire  a  proprietary  interest  in the
Corporation's success. You have been granted, subject to the following terms and
conditions,  the right to acquire shares of the Corporation's stock. The date of
grant will be _______,  1993. The terms and  conditions  governing this grant to
you are set forth below.

1.       Subject to the terms and conditions of the Plan (a copy of
         which is attached hereto and made a part hereof) and this
         letter, the Corporation grants to you the option to purchase
         from the Corporation all or any part of an aggregate number
         of two thousand one hundred (2,100) shares of stock
         (hereinafter such shares of stock are referred to as the
         "optioned shares" and the option to purchase the optioned
         shares is referred to as the "option").

2.       The price to be paid for the optioned  shares shall be 100% of the fair
         market value of the stock as of ______, 1993.

3.       Subject to the terms and  conditions  of the Plan and this letter,  the
         options may be exercised by you while in the employ of the Corporation,
         in whole or in part, from time to time. You can exercise options for up
         to seven hundred (___) shares  beginning  June 1, 1994, for up to seven
         hundred (___) shares beginning June 1, 1995 and for up to seven hundred
         (___) shares beginning June 1, 1996. The


<PAGE>



         Corporation  will use its best  efforts to  register  option  shares of
         stock under the  Securities  Act of 1933, as amended,  using a Form S-8
         registration statement.
                                                     

         Optioned  shares  must be  purchased  within  5 years  from the date of
         grant,  _______,  1993.  That is,  all  options  must be  exercised  by
         _______,  1998,  provided you remain an employee.  Upon  termination of
         your  employment,  option  shares must be  purchased as provided for in
         Section  6d of the  Plan  for any  shares  which  you  have a right  to
         purchase as of the date of termination.

4.       In the event that the shares of the  Corporation's  stock, as presently
         constituted,  shall be  changed,  as  provided  for in Section 7 of the
         Plan, the number of options issued to you will be adjusted accordingly.

5.        The options may be  exercised  only by written  notice,  delivered  or
          mailed by registered or certified  mail  addressed to the Treasurer of
          the Corporation at the Corporation's  principal business office.  Such
          notice shall be  accompanied  by payment of the entire option price of
          the  optioned  shares  being  purchased  either  (i)  in  cash  or its
          equivalent,  (ii) by  tendering  previously  acquired  shares of stock
          valued at their Fair  Market  Value at the time of exercise as long as
          the tendered shares have been held by you for at least six months,  or
          (iii) by any  combination of (i) and (ii).  Fair Market Value shall be
          determined  as provided  in  Paragraph  6a of the Plan.  Any shares of
          stock  tendered in payment for optioned  shares shall be duly endorsed
          in blank or accompanied  by stock powers duly endorsed in blank.  Upon
          receipt of the payment of the entire price of the  optioned  shares so
          purchased,  certificates  representing  such optioned  shares shall be
          issued to you.  The optioned  shares so purchased  shall be fully paid
          and nonassessable except insofar as statutory liability may be imposed
          under any applicable law.

6.       Upon  dissolution  or  liquidation  of  the  Corporation,   or  upon  a
         reorganization, merger or consolidation in which the Corporation is not
         the surviving corporation, or upon the


<PAGE>



         sale of substantially all of the property of the Corporation to another
         corporation,   the  Plan  and  the  options  issued   thereunder  shall
         terminate,   unless   provisions  are  made  in  connection  with  such
         transaction for the assumption of options  theretofore  granted, or for
         the  substitution  for such  options of new  options  of the  successor
         employer   corporation  or  a  parent  or  subsidiary   thereof,   with
         appropriate  adjustments  as to the  number and kinds of shares and the
         per  share  exercise  prices.  In the  event of such  termination,  all
         outstanding  options shall be  exercisable in full for at least 30 days
         prior to the termination  date whether or not  exercisable  during such
         period.  This  acceleration for vesting will also occur if at least 50%
         or more of the voting stock of the Corporation is sold either through a
         tender offer or otherwise to a party or an affiliated group of parties.
         For purposes of this  Paragraph 6,  Corporation  refers to Mid Atlantic
         Medical  Services,  Inc.,  MD-Individual  Practice  Association,  Inc.,
         and/or  Physicians  Health  Plan  of  Maryland,  Inc.,  jointly  and/or
         separately.

                                                        -3-

7.       You shall not be deemed for any  purposes  to be a  stockholder  of the
         Corporation with respect to any shares which may be acquired  hereunder
         except to the extent that the options shall have been exercised and the
         stock certificate issued with respect thereto.

8.       The options herein granted shall not be  transferable  by you otherwise
         than by will, by the laws of descent and  distribution or pursuant to a
         qualified  domestic  relations order as defined by the Internal Revenue
         Code of 1986, as amended,  or Title I of the Employee Retirement Income
         Security Act, or the rules thereunder.

9.       You agree for yourself and your heirs, legatees, and legal
         representatives, with respect to all shares of stock
         acquired pursuant to the terms and conditions of the Plan
         and this letter (or any other shares of stock issued
         pursuant to a stock dividend or stock split thereon or any
         securities issued in lieu thereof or in substitution or
         exchange therefore), that you and your heirs, legatees and
         legal representatives will not sell or otherwise dispose of
         these shares except pursuant to an effective registration
         statement under the Securities Act of 1933, as amended ("the
         Act"), or except in a transaction which, in the opinion of
         counsel for the Corporation, is exempt from registration
         under the Act.  Further, the Corporation shall not be
         required to sell or issue any shares under an outstanding
         option if, in the opinion of the Corporation, (a) the
         issuance of such shares would constitute a violation by you
         or the Corporation of any applicable law of regulation of
         any government authority or (b) the consent or approval of
         any governmental body is necessary or desirable as
         condition of, or in connection with, the issuance of such
         shares.

10.      The existence of the options herein granted shall not affect
         in any way the right or power of the Corporation or its
         directors or stockholders to make or authorize any or all
         adjustments, recapitalizations, reorganizations, or other
         changes in the Corporation's capital structure or its
         business, or any merger or consolidation of the Corporation,
         or any issuance of bonds, debentures, preferred or prior
         preferences stock ahead of or affecting the stock or the
         rights thereof, or dissolution or liquidation of the
         Corporation, or any sale or transfer of all or any part of
         its assets or business, or any other corporation act or

                      1998 NON-QUALIFIED STOCK OPTION PLAN

Article I.  Purpose, Adoption and Term of the Plan

         1.01 Purpose.  The purpose of the Mid Atlantic Medical  Services,  Inc.
1998 NonQualified  Stock Option Plan (hereinafter  referred to as the "Plan") is
to advance  the  interests  of the  Company  (as  hereinafter  defined)  and its
Subsidiaries  (as  hereinafter  defined) by  encouraging  and  providing for the
acquisition  of an equity  interest  in the Company by  non-employee  directors,
officers and key employees through the grant of options to purchase Common Stock
(as  hereinafter  defined).  The Plan will  enable  the  Company  to retain  the
services  of  non-employee  directors  and key  employees  upon whose  judgment,
interest, and special effort the successful conduct of its operations is largely
dependent and to compete  effectively with other enterprises for the services of
non-employee  directors,  officers  and key  employees  as may be needed for the
continued improvement of its business.

         1.02 Adoption and Term. The Plan shall become effective on May 1, 1998,
subject to the prior  approval  of a simple  majority  of the  holders of Common
Stock  represented,  by person or by proxy, and entitled to vote at an annual or
special  meeting of the holders of Common  Stock.  The Plan shall  terminate  on
April 30, 2003,  or such earlier  date as shall be  determined  by the Board (as
hereinafter  defined);  provided,  however,  that,  in the event the Plan is not
approved by a simple  majority of the holders of Common  Stock  represented,  by
person or by proxy,  and entitled to vote at an annual or special  meeting at or
before the Company's  1998 annual  meeting of holders of Common Stock,  the Plan
shall terminate on such date and any Options (as hereinafter defined) made under
the Plan prior to such date shall be void and of no force and effect.

Article II.  Definitions

         For purposes of the Plan,  capitalized  terms shall have the  following
meanings:

         2.01 "Beneficiary" means an individual, trust or estate who or that, by
will or the  laws of  descent  and  distribution,  succeeds  to the  rights  and

Participant's death.

         2.02     "Board" means the Board of Directors of the Company.

         2.03 "Cause" means, with respect to a Participant who is a Non-Employee
Director,  removal as a director by the holders of Common  Stock or by the Board
for cause; provided, however, that, if a Non-Employee Director is not a director

Subsidiary  on whose  Board of  Directors  he or she  serves or by such Board of
Directors for cause.

time to time,  or any  successor  thereto.  References  to a section of the Code
shall include that section and any comparable  section or sections of any future
legislation that amends, supplements, or supersedes said section.

         2.05  "Committee"  means a committee of the Board as may be  appointed,
from time to time, by the Board.

                  (a)  The  Board  may  appoint  more  than  one   Committee  to
         administer  the  Plan.  If it  appoints  more than one  Committee,  one
         Committee  (the "Stock Option  Committee")  shall have the authority to
         grant Options to a Participant  who is either,  at the Date of Grant of
         the Option, a "covered employee" as defined in Section 162(m) or who is
         subject to Section 16 of the  Exchange  Act;  however,  such  Committee
         shall also have the authority to grant  Options to other  Participants.
         The Stock Option  Committee shall be composed of at least two directors
         of the Company, each of whom is a "non-employee director" as defined in
         Rule 16b-3 and an  "outside  director"  within  the  meaning of Section
         162(m).  If, however,  at least two of the Company's  directors are not
         both  "non-employee  directors" and "outside  directors," the Board may
         grant  Options to a Participant  who is either a "covered  employee" or
         subject to Section 16 of the Exchange  Act, in which case the Board may
         also administer the Plan and the term  "Committee" as used herein shall
         also include the Board.  The other  Committee (the "Select  Committee")
         shall be  composed of at least one  director,  who may be an officer of
         the Company. The Select Committee shall have authority to grant Options
         to a Participant who is not, at the Date of Grant of the Option, either
         a "covered employee" as defined in Section 162(m) or subject to Section
         16 of the Exchange Act.

                  (b) The Board may, from time to time,  appoint members of each
         Committee  in  substitution  for  those  members  who  were  previously
         appointed and may fill vacancies, however caused, in the Committee.

                  (c) The Stock Option  Committee and the Select Committee shall
         each have the power and authority to administer  the Plan in accordance
         with Article III with respect to particular classes of Participants (as
         specified  in  Section  2.05(a))  and,  when  used  herein,   the  term
         "Committee"  shall mean either the Stock Option Committee or the Select
         Committee if the Board  appoints  more than one Committee to administer
         the Plan. If, however,  there is a conflict between the  determinations
         made by the  Stock  Option  Committee  and the  Select  Committee,  the
         determinations made by the Stock Option Committee shall control.

         2.06 "Common Stock" means the Common Stock, par value $.01 per share, 
         of the Company.

be  computed  as of the  last  date  preceding  such  date on  which a sale  was
reported;  provided,  further, that, if any such exchange or quotation system is
closed on any day on which Fair Market  Value is to be  determined,  Fair Market
Value shall be determined as of the first date  immediately  preceding such date
on which such  exchange or quotation  system was open for trading.  In the event
the Common Stock is not admitted to trade on a securities  exchange or quoted on

shall be as determined in good faith by the Committee,  in its sole and absolute
discretion, which determination may be based on, among other things, the opinion
of one or more independent and reputable appraisers qualified to value companies
in the  Company's  line of business.  Notwithstanding  the  foregoing,  the Fair
Market  Value of a share of Common  Stock shall never be less than par value per

Article V.  Participation

such  officers  and other key  employees  of the  Company  or its  Subsidiaries,
whether or not  directors  of the  Company,  as the  Committee,  in its sole and
absolute   discretion,   may  designate  from  time  to  time.  In  making  such
designation,  the  Committee  may take into  account the nature of the  services
rendered  by the  officers  and  key  employees,  their  present  and  potential
contributions  to the  success of the  Company,  and such  other  factors as the
Committee,  in  its  sole  and  absolute  discretion,  may  deem  relevant.  The
Committee's designation of an Employee Participant in any year shall not require
the Committee to designate such person to receive Options in any other year. The
Committee  shall  consider  such  factors  as it deems  pertinent  in  selecting
Employee Participants and in determining the type and

                                                     - 5 -

amount of their respective  Options. A Participant may hold more than one Option
granted under the Plan. During the term of the Plan, no Employee Participant may
receive  Options to purchase more than one million  shares of Common Stock under
the Plan.

         Non-Employee  Directors shall receive Non-Employee  Director Options in
accordance  with  Article  VII,  the  provisions  of  which  are  automatic  and
non-discretionary in operation.  Non-Employee Directors shall not be eligible to
receive any other Options under the Plan unless they are no longer  Non-Employee
Directors on the Date of Grant of such Options.

Article VI.  Stock Options

         6.01 Grant of Option. Any Option granted under the Plan shall have such
terms as the  Committee  may,  from  time to time,  approve,  and the  terms and
conditions of Options need not be the same with respect to each Participant.

         6.02 Terms of Options.  Options granted under the Plan shall be subject
to the following terms and conditions and shall be in such form and contain such
additional terms and conditions, not inconsistent with the terms of the Plan, as
the Committee shall deem desirable:

                  (a) Option  Price.  The option price per share of Common Stock
         purchasable under an Option shall be determined by the Committee at the
         time of grant but shall not be less than 100% of the Fair Market  Value
         of a share of  Common  Stock on the Date of Grant;  provided,  however,
         that, except as required by Rule 16b- 3 with respect to Options granted
         to persons  subject to Section 16 of the Exchange  Act, no amendment of
         an Option  shall be deemed to be the grant of a new Option for purposes
         of this Section  6.02(a).  Notwithstanding  the  foregoing,  the option
         price per share of Common  Stock of an Option  shall never be less than
         par value per share.

                  (b) Option Term. The term of each Option shall be fixed by the
         Committee,  but no Option  shall be  exercisable  more than five  years
         after the Date of Grant.

                  (c)  Exercisability.  An  Option  Agreement  with  respect  to
         Options may contain such performance targets, waiting periods, exercise
         dates and  restrictions on exercise  (including,  but not limited to, a
         requirement  that an Option is exercisable  in periodic  installments),
         and restrictions on transfer of the underlying  shares of Common Stock,
         if any, as may be determined by the Committee at the time of grant.  To
         the  extent  not   exercised,   installments   shall  cumulate  and  be
         exercisable,   in  whole  or  in  part,  at  any  time  after  becoming
         exercisable,  subject to the limitations set forth in Sections 6.02(b),
         (f) and (g).

                  (d)  Method  of  Exercise.  Subject  to  whatever  installment
         exercise and waiting  period  provisions  that apply under Section 6.02
         (c) above,  Options  may be  exercised  in whole or in part at any time
         during the term of the Option,  by giving written notice of exercise to
         the  Company  specifying  the  number of  shares of Common  Stock to be
         purchased.  Such notice shall be  accompanied by payment in full of the
         purchase  price in such form as the  Committee  may  accept  (including
         payment in accordance with a cashless  exercise program approved by the
         Committee).  If and to the extent the Committee  determines in its sole
         and absolute  discretion at or after grant,  payment in full or in part
         may also be made in the form of shares of Common Stock already owned by
         the Participant (and for which the Participant has good title, free and
         clear of any liens or  encumbrances)  based on the Fair Market Value of
         the  shares  of  Common  Stock  on the date the  Option  is  exercised;
         provided, however, that any already owned Common Stock used for payment
         must have  been held by the  Participant  for at least six  months.  No
         Common Stock shall be issued on exercise of an Option until payment, as
         provided herein,  therefor has been made. A Participant shall generally
         have the  right to  dividends  or other  rights of a  stockholder  with
         respect to Common  Stock  subject to the Option only when  certificates
         for shares of Common Stock are issued to the Participant.

                  (e)   Non-Transferability  of  Options.  No  Option  shall  be
         transferable by the Participant  otherwise than by will, by the laws of
         descent and distribution, or pursuant at a qualified domestic relations
         order as defined by the Code, Title I of ERISA or the rules thereunder.

                  (f) Acceleration or Extension of Exercise Time. The Committee,
         in its sole and  absolute  discretion,  shall have the right (but shall
         not in any case be  obligated)  to  permit  purchase  of  Common  Stock
         subject to any Option granted to an Employee  Participant  prior to the
         time such Option would otherwise become  exercisable under the terms of
         the Option  Agreement.  In  addition,  the  Committee,  in its sole and
         absolute discretion, shall have the right (but shall not in any case be
         obligated) to permit any Option  granted to an Employee  Participant to
         be  exercised  after  its  expiration  date,  subject,  however  to the
         limitation set forth in Section 6.02(b).

                  (g) Exercise of Options Upon  Termination of  Employment.  The
         following provisions apply to Options granted to Employee Participants:

               (i) Exercise of Vested Options Upon Termination of
                  Employment.

                                    (A)  Termination.  Unless the Committee,  in
                           its  sole and  absolute  discretion,  provides  for a
                           shorter  or  longer  period  of  time  in the  Option
                           Agreement  or a longer  period of time in  accordance
                           with Section 6.02(f), upon an Employee  Participant's
                           Termination of Employment other than by

                                                     - 7 -

                           reason   of  death  or   Disability,   the   Employee
                           Participant may, within three months from the date of
                           such  Termination of Employment,  exercise all or any
                           part of his or her Options as were exercisable at the
                           date  of  Termination  of  Employment.  In no  event,
                           however,  may any Option be exercised  later than the
                           date determined pursuant to Section 6.02(b).

                                    (B) Disability. Unless the Committee, in its
                           sole and absolute discretion,  provides for a shorter
                           or longer period of time in the Option Agreement or a
                           longer  period  of time in  accordance  with  Section
                           6.02(f),  upon an Employee  Participant's  Disability
                           Date, the Employee  Participant  may, within one year
                           after the Disability Date,  exercise all or a part of
                           his or her  Options,  whether or not such  Option was
                           exercisable on the  Disability  Date, but only to the
                           extent  not  previously   exercised.   In  no  event,
                           however,  may any Option be exercised  later than the
                           date determined pursuant to Section 6.02(b).

                                    (C) Death. Unless the Committee, in its sole
                           and  absolute  discretion,  provides for a shorter or
                           longer  period of time in the Option  Agreement  or a
                           longer  period  of time in  accordance  with  Section
                           6.02(f),  in the  event of the  death of an  Employee
                           Participant  while  employed  by  the  Company  or  a
                           Subsidiary,  the right of the Employee  Participant's
                           Beneficiary  to exercise the Option in full  (whether
                           or not all or any part of the Option was  exercisable
                           as of the date of death of the Employee  Participant,
                           but  only to the  extent  not  previously  exercised)
                           shall expire upon the expiration of one year from the
                           date of the  Employee  Participant's  death or on the
                           date of expiration of the Option determined  pursuant
                           to Section 6.02(b), whichever is earlier.

                            (ii) Expiration of Unvested Options Upon Termination
                  of Employment.  Subject to Sections 6.02(f) and  6.02(g)(i)(B)
                  and (C), to the extent all or any part of an Option granted to
                  an Employee  Participant was not exercisable as of the date of
                  Termination of Employment, such right shall expire at the date
                  of  such  Termination  of  Employment.   Notwithstanding   the
                  foregoing,  the Committee, in its sole and absolute discretion
                  and under  such terms as it deems  appropriate,  may permit an
                  Employee  Participant who will continue to render  significant
                  services  to the  Company  or a  Subsidiary  after  his or her
                  Termination  of Employment to continue to accrue  service with
                  respect to the right to exercise his or her Options during the
                  period in

                                                     - 8 -

                  which the individual continues to render such services.

Article VII.  Non-Employee Director Options

         7.01 Grant of Non-Employee  Director Options;  Exercise Price; Term. On
May 1, 1998,  each person who is a  Non-Employee  Director on such date shall be
granted a  Non-Employee  Director  Option to  purchase  the  number of shares of
Common Stock determined in accordance with Section 7.02. A Non-Employee Director
shall only receive one  Non-Employee  Director Option on May 1, 1998, even if he
or she serves as a Non-Employee Director of the Company and/or of one or more of
its Subsidiaries.

         The exercise price per share for Non-Employee Director Options shall be
the Fair  Market  Value of a share of  Common  Stock on the Date of  Grant.  All
Non-Employee Director Options shall have a five year term.

         7.02 Number of Shares. Each Non-Employee  Director Option shall entitle
the holder to purchase 3,000 shares of Common Stock; provided, however, that, if
a  Non-Employee  Director is not a  Non-Employee  Director of the Company on the
Date of Grant of the Option, his or her Non- Employee Director Option shall only
entitle him or her to purchase 2,400 shares of Common Stock.


                  (a) Adjustments. Such number of shares is, however, subject to
         increase  (but not  decrease)  based on the  application  of the factor
         described in Section 7.02(b) below; provided,  however, that the number
         of shares of Common Stock  covered by a  Non-Employee  Director  Option
         shall be  increased  by one or two  shares of Common  Stock so that the
         number of covered  shares is divisible  by three and provided  further,
         however,  that a  Non-Employee  Director  Option  shall not entitle the
         holder  to  purchase   more  than  6,000  shares  (4,800  shares  if  a
         Non-Employee  Director is not a Non-Employee Director of the Company on
         the Date of Grant of the Option) of Common Stock.

                  (b) Number of Years of  Service.  Each  Non-Employee  Director
         Option shall  entitle the holder to purchase an  additional  150 shares
         (120 shares if a Non- Employee Director is not a Non-Employee  Director
         of the Company on the Date of Grant of the Option) of Common  Stock for
         each calendar year the  Non-Employee  Director has served as a director
         of the Company or of one of its Subsidiaries, but only if such calendar
         year has been completed prior to the Date of Grant of the Non- Employee
         Director Option.  The following rules shall apply in calculating  years
         of service as a director:

                           (i)  Partial  Service.  If a person  has  served as a
                  director  of  the  Company  or as a  director  of  any  of its
                  Subsidiaries at any time during a calendar year, that calendar
                  year shall count as one year of service even if the person did
                  not serve as such for a full year;

                                                     - 9 -

<PAGE>





                           (ii) Multiple Service. Notwithstanding the foregoing,
                  service as a director of the  Company  and/or as a director of
                  one or more of its Subsidiaries during any calendar year shall
                  not be double counted.  Accordingly, if a person has served as
                  a director  of the Company and as a director of one or more of
                  its  Subsidiaries  during a calendar year,  that calendar year
                  shall count as only one year of service; and

                           (iii)  Service as an  Employee.  Notwithstanding  the
                  foregoing, if a Non-Employee Director served as an employee of
                  the Company or of one of its Subsidiaries at any time during a
                  calendar year, that calendar year shall not count as a year of
                  service.

         7.03  Exercisability.  Each  Non-Employee  Director Option shall become
exercisable  cumulatively  in three equal  installments on June 1, 1999, June 1,
2000 and June 1, 2001; provided,  however,  that, if a Non-Employee  Director is
removed for Cause, any Option held by such Non- Employee Director shall cease to
continue to become exercisable on or after the date of such removal.

         7.04 Termination. If a Non-Employee Director's service with the Company
terminates  for  any  reason  or if  such  person  ceases  to be a  Non-Employee
Director,  such Option shall continue to become  exercisable in accordance  with
Section 7.03 and may be exercised until the expiration of the stated term of the
Option.  Accordingly, if a Non-Employee Director is removed for Cause, he or she
may  continue to exercise  his or her  Non-Employee  Director  Option  until the
expiration  of the stated term of such  Option,  but only to the extent that (a)
such Option became  exercisable prior to the date of such removal and (b) it was
not previously exercised.

         7.05 Other  Plan  Provisions.  All  applicable  provisions  of the Plan
(other than  Sections  6.02(f) and (g)) not  inconsistent  with this Article VII
shall apply to Options granted to Non-Employee Directors.

         Article VIII.  Terms Applicable to All Options Granted Under the Plan

         8.01 Plan Provisions  Control Option Terms. The terms of the Plan shall
govern all Options  granted under the Plan,  and in no event shall the Committee
have the  power to grant to a  Participant  any  Option  under  the Plan that is
contrary to any provisions of the Plan. In the event any provision of any Option
granted  under  the Plan  shall  conflict  with any of the  terms in the Plan as
constituted  on the  Date of  Grant  of such  Option,  the  terms in the Plan as
constituted on the Date of Grant of such Option shall control.

         8.02 Option Agreement. No person shall have any rights under any Option
granted under the Plan unless and until the Company and the  Participant to whom
such Option shall have been granted  shall have executed and delivered an Option
Agreement  authorized  by the  Committee  expressly  granting the Option to such
person and containing provisions setting forth the terms of the

                                                     - 10 -


<PAGE>




Option.  If there is any conflict between the provisions of an Option Agreement 
and the terms of the Plan, the terms of the Plan shall control.

         8.03  Modification  of Option  After  Grant.  Except as provided by the
Committee,  in its sole and absolute  discretion,  in the Option Agreement or as
provided in Section 8.05, no Option granted under the Plan to a Participant  may
be modified (unless such modification does not materially  decrease the value of
the Option) after the Date of Grant except by express written  agreement between
the Company and the Participant,  provided that any such change (a) shall not be
inconsistent  with the  terms of the  Plan,  and (b)  shall be  approved  by the
Committee.

         8.04 Taxes.  The Company shall be entitled,  if the Committee  deems it
necessary or desirable,  to withhold (or secure payment from the  Participant in
lieu of withholding)  the amount of any withholding or other tax required by law
to be withheld or paid by the Company with respect to any Common Stock  issuable
under such  Participant's  Option,  and the Company may defer issuance of Common
Stock  upon  the  grant or  exercise  of an  Option  unless  indemnified  to its
satisfaction  against  any  liability  for any  such  tax.  The  amount  of such
withholding  or tax payment shall be determined by the Committee or its delegate
and  shall  be  payable  by the  Participant  at  such  time  as  the  Committee
determines.  A  Participant  shall be  permitted  to  satisfy  his or her tax or
withholding obligation by (a) having cash withheld from the Participant's salary
or other compensation payable by the Company or a Subsidiary, (b) the payment of
cash by the  Participant  to the  Company,  (c) the  payment in shares of Common
Stock already owned by the Participant  valued at Fair Market Value,  and/or (d)
the withholding from the Option,  at the appropriate time, of a number of shares
of Common  Stock  sufficient,  based upon the Fair  Market  Value of such Common
Stock, to satisfy such tax or withholding  requirements.  The Committee shall be
authorized,  in its  sole  and  absolute  discretion,  to  establish  rules  and
procedures  relating  to any such  withholding  methods  it deems  necessary  or
appropriate  (including,  without  limitation,  rules and procedures relating to
elections by Participants who are subject to the provisions of Section 16 of the
Exchange Act to have shares of Common Stock withheld from an Award to meet those
withholding obligations).

         8.05     Adjustments to Reflect Capital Changes; Change in Control.

                  (a) Recapitalization. The number and kind of shares subject to
         outstanding  Options,  the  purchase  price or  exercise  price of such
         Options,  the amount of Non- Employee Director Options to be granted on
         any date under Section  7.02,  the limit set forth in the last sentence
         of the first  paragraph of Section 5.01 of the Plan, and the number and
         kind of shares  available  for Options  subsequently  granted under the
         Plan shall be  appropriately  adjusted to reflect  any stock  dividend,
         stock split,  combination or exchange of shares, merger,  consolidation
         or other change in  capitalization  with a similar  substantive  effect
         upon the Plan or the  Options  granted  under the Plan.  The  Committee
         shall have the power and sole and absolute  discretion to determine the
         nature and amount of the adjustment to be made in each case.

                  (b)  Sale or Reorganization.  After any reorganization,
 merger, or

                                                     - 11 -

<PAGE>





         consolidation  in which  the  Company  is the  surviving  entity,  each
         Participant shall, at no additional cost, be entitled upon the exercise
         of an Option outstanding prior to such event to receive (subject to any
         required  action by  stockholders),  in lieu of the number of shares of
         Common Stock receivable on exercise pursuant to such Option, the number
         and  class  of  shares  of  stock or  other  securities  to which  such
         Participant  would  have  been  entitled  pursuant  to the terms of the
         reorganization,  merger,  or  consolidation  if,  at the  time  of such
         reorganization, merger, or consolidation, such Participant had been the
         holder of record  of a number  of shares of Common  Stock  equal to the
         number of shares of Common  Stock  receivable  on exercise  pursuant to
         such Option.  Comparable rights shall accrue to each Participant in the
         event of successive reorganizations,  mergers, or consolidations of the
         character described above.

                  (c) Options to Purchase Stock of Acquired Companies. After any
         reorganization,  merger, or consolidation in which the Company shall be
         a surviving entity,  the Committee may grant substituted  Options under
         the provisions of the Plan,  replacing old options granted under a plan
         of another party to the reorganization,  merger, or consolidation whose
         stock subject to the old options may no longer be issued following such
         reorganization, merger, or consolidation. The foregoing adjustments and
         manner of application of the foregoing  provisions  shall be determined
         by  the  Committee  in its  sole  and  absolute  discretion.  Any  such
         adjustments may provide for the elimination of any fractional shares of
         Common Stock that might otherwise become subject to any Options.

                  (d)  Changes  in  Control.   (i)  Upon  the   dissolution   or
         liquidation  of the Company,  (ii) upon a  reorganization,  merger,  or
         consolidation  in which the Company is not the  surviving  corporation,
         (iii) upon the sale of  substantially  all of the property or assets of
         the Company to another corporation,  or (iv) if at least 50% or more of
         the voting  stock of the Company is sold either  through a tender offer
         or otherwise  to a party or an  affiliated  group of parties,  then the
         Plan  and  the  Options  issued  thereunder  shall  terminate,   unless
         provisions  are  made  in  connection  with  such  transaction  for the
         assumption of Options theretofore  granted, or for the substitution for
         such Options of new options of the successor corporation or a parent or
         subsidiary  thereof,  with appropriate  adjustment as to the number and

         date on which Options may become  exercisable  pursuant to this Section
         8.05(d).

every Option at any time  granted  under the Plan shall be  interpreted  in such
manner as to be effective and valid under  applicable  law, but if any provision

         authority  to  amend  the Plan at any time it is  deemed  necessary  or
         appropriate;  provided,  however, that the Board shall not, without the
         affirmative  approval  of a simple  majority  of the  holders of Common
         Stock,  represented,  by person or by proxy, and entitled to vote at an
         annual or special  meeting of the  holders  of Common  Stock,  make any
         amendment that requires  stockholder  approval under  applicable law or
         rule, unless the Board determines that compliance with such law or rule
         is no  longer  desired  with  respect  to the  Plan as a  whole  or the
         provision to be amended.  No  termination or amendment of the Plan may,
         without  the  consent  of the  Participant  to whom  any  Option  shall
         theretofore  have been  granted  under the Plan,  adversely  affect the
         right of such individual under such Option; provided, however, that the
         Committee may, in its sole and absolute  discretion,  make provision in
         an Option  Agreement for such amendments that, in its sole and absolute
         discretion, it deems appropriate.

                  (b) Termination.  The Board shall have the right and the power
         to terminate the Plan at any time. No Option shall be granted under the
         Plan after the termination of the Plan, but the termination of the Plan
         shall not have any other effect and any

         Option  outstanding  at the time of the  termination of the Plan may be
         amended and exercised and may vest after termination of the Plan at any
         time prior to the  expiration  date of such  Option to the same  extent
         such Option could have been amended or would have been  exercisable  or
         vest had the Plan not terminated.

         8.17  Costs  and   Expenses.   All  costs  and  expenses   incurred  in
administering the Plan shall be borne by the Company.

                        1998 SENIOR MANAGEMENT BONUS PLAN
                  

Participants  in the 1998 Senior  Management  Bonus Plan  ("Bonus  Plan")  shall
include all full-time  non-sales  positions  Level 17 and above,  which includes
those  individuals  who could  possibly  be  affected  by Section  162(m) of the
Internal  Revenue Code,  including  but not limited to the CEO. This  definition
includes  all  full-time  non-sales  employees  who are Level 17 and above as of
March 1, 1998 and all full-time non-sales employees who are promoted to or hired
at a Level 17 or above after March 1, 1998. Bonuses will be solely predicated on
the consolidated  earnings  performance of Mid Atlantic Medical  Services,  Inc.
(MAMSI) and will be accrued on at least a quarterly  basis as  documented by the
year end audited financial statements.

Bonuses shall be paid according to the following guidelines:

1.       Minimum  Bonus-  Minimum  bonuses  shall  be  paid  if  MAMSI  and  its
         consolidated  subsidiaries (the "Company")  achieve a profit of $33.750
         million before income taxes,  expansion or acquisition costs, and prior
         to the  physicians'  return of  withhold  and  payment  of  physicians'
         bonuses.

2.       Maximum Bonus- Maximum bonuses shall be paid if the Company  achieves a
         profit of $52.50 million before income taxes,  expansion or acquisition
         costs,  and prior to the physicians'  return of withhold and payment of
         physicians' bonuses.

3.       Pro-ration- In the event that the Company earns between $33.750 million
         and $52.50 million, bonus payments will be pro-rated accordingly.

4.       Bonus Base- In general, bonus payments will be calculated based on the 
         salary level on March 1, 1998.  With respect to new participants who 
         are hired or initially promoted to a full-time non-sales position Level
         17 or higher after March 1, 1998, the bonus will be calculated at the 
         initial Level 17 or higher salary.  With respect to new participants 
         who are hired or initially promoted to a full-time non-sales position 
         Level 17 or higher after March 1, 1998, the bonus will be calculated
         at the initial Level 17 or higher salary.With respect to a participant
         who is demoted during 1998, the amount will be calculated on a pro-rata
         basis based on the portion of the year that the employee was employed
         in a full-time non-sales position Level 17 or higher.

5.       New Employees-  New full-time  employees or those who are promoted to a
         full-time  non-sales  position  Level  17 or  higher  during  1998  are
         eligible to  participate  in the Bonus Plan.  The bonus payment will be
         pro-rated accordingly for the portion of the year that the employee was
         employed in a full-time non-sales position Level 17 or higher.

6.       Termination- No bonus shall be paid to bonus participants who terminate
         or are terminated by the Company prior to the year end. In the event of
         retirement or death, the employee or his\her beneficiary will receive a
         pro-rated portion of the bonus.

7.       Time of  Payment-  Bonus  payments  shall  be  distributed  immediately
         following  the receipt of the audited  financial  statement(s)  for the
         Company for the year 1998.

8.       Bonus   Percentages-   The   distribution  of  the  bonus  payments  to
         participants  shall be limited  according to the  following  percentage
         ranges:

         CEO                                                          12.5 - 50%
         Executive Staff (Level 18 & above, excluding CEO)             6.0 - 35%
         Senior Staff (Level 17)                                       5.5 - 30%

9.       Relationship  to Other  Bonus  Plan- This  Bonus Plan is  substantially
         similar  to the 1998  Management  Bonus  Plan for  full-time  non-sales
         employees  Level 10 to Level 16. The  primary  differences  between the
         Bonus  Plan  and the 1998  Management  Bonus  Plan  are the  percentage
         payments available to personnel and the personnel covered.

10.      Interpretation  of the  Bonus  Plan by the  Board  of  Directors-  If a
         question as to the the  interpretation  of the Bonus Plan  arises,  the
         Board of Directors may  interpret  the Bonus Plan.  The decision of the
         Board is final.

11.      Amendment-  The Board of  Directors  may not  amend  the Bonus  Plan to
         materially increase the amounts payable thereunder to participants.




                           1998 MANAGEMENT BONUS PLAN

Participants  in the 1998  Management  Bonus Plan shall  include  all  full-time
non-sales  positions  from  Level  10 up to Level  16.  Bonuses  will be  solely
predicated on the  consolidated  earnings  performance  of Mid Atlantic  Medical
Services,  Inc.  (MAMSI)  and will be accrued on at least a  quarterly  basis as
documented by the year end audited financial statements.

Bonuses shall be paid according to the following guidelines:

1.       Minimum  Bonus-  Minimum  bonuses  shall  be  paid  if  MAMSI  and  its
         consolidated  subsidiaries (the "Company")  achieve a profit of $33.750
         million before income taxes,  expansion or acquisition costs, and prior
         to the  physicians'  return of  withhold  and  payment  of  physicians'
         bonuses.

2.       Maximum Bonus- Maximum bonuses shall be paid if the Company  achieves a
         profit of $52.50 million before income taxes,  expansion or acquisition
         costs,  and prior to the physicians'  return of withhold and payment of
         physicians' bonuses.

3.       Pro-ration- In the event that the Company earns between $33.750 million
         and $52.50 million, bonus payments will be pro-rated accordingly.

4.       Bonus Base- In general,  bonus  payments will be calculated on cash
         payments  made during the year for base salary,  which would take into
         account salary  increases due to promotion or merit  increases  (other
         than those to Level 17 or higher). Pro-rated calculations will be made
         at each salary level for the portion of the year that the new level is
         in effect.  If a participant  is demoted to under a Level 10 position,
         and remains in an under Level 10 position until December 31, 1998, the
         employee  will  received a pro-rata  bonus payment based upon the time
         the  participant  was in a  full-time  non-sales  Level  10 or  higher
         position  during  1998.   Similarly,   the  employee  is  promoted  or
         re-promoted  to a Level 10 or higher,  the  employee  is  eligible  to
         participate  in the Bonus  Plan on a  pro-rata  basis for all the time
         periods  during  which the  participant  was in a full-time  non-sales
         Level 10 or higher position during 1998.

5.       New  Employees-  New  full-time  non-sales  employees  are  eligible to
         participate  in the Bonus Plan.  The bonus  payment  will be  pro-rated
         accordingly  for the portion of the year that the employee was employed
         at a full-time non-sales Level 10 or higher position.

6.       Termination- No bonus shall be paid to bonus  participants  who 
         terminate or are terminated by the Company prior to year end. In the 
         event of retirement or death, the employee or his/her  beneficiary will
         receive a pro-rated  portion of the bonus.

         Level 15                                                      4.5 - 21%
         Level 14                                                      4.0 - 16%
         Level 12 & 13                                                 3.5 - 12%
         Level 10 & 11                                                 2.5 -  7%
 
9.       Relationship  to Other  Bonus  Plan- This  Bonus Plan is  substantially
         similar  to  the  1998  Senior  Management  Bonus  Plan  for  full-time
         non-sales  employees  Level  17 to Level  20,  including  the CEO.  The
         primary  differences  between  the  Bonus  Plan  and  the  1998  Senior

Amendment of 1994 Non-Qualified Stock Option Plan

         FURTHER RESOLVED,  that Section 4 of the Mid Atlantic Medical Services,
Inc.  1994  Non-Qualified  Stock Option Plan ("1994 Plan") be, and it hereby is,
amended to read in its entirety as follows:

                  4.       COMMITTEE.  The "Committee" means a committee of the
         Board of Directors of MAMSI ("Board") as may be appointed, from time to
         time, by the Board.

                  a. The Board may appoint more than one Committee to administer
         the Plan. If it appoints more than one  Committee,  one Committee  (the
         "Stock Option  Committee") shall have the authority to grant Options to
         a key  employee  who is either,  at the date of grant of the Option,  a
         "covered employee" as defined in Section 162(m) of the Internal Revenue
         Code of 1986,  as  amended  ("Code"),  and the  regulations  thereunder
         (collectively, "Section 162(m)") or who is subject to Section 16 of the
         Securities Exchange Act of 1934, as amended ("Exchange Act");  however,
         such Committee  shall also have the authority to grant Options to other
         key employees. The Stock Option Committee shall be composed of at least
         two directors of MAMSI,  each of whom is a  "non-employee  director" as
         defined in Rule 16b-3 as  promulgated  by the  Securities  and Exchange
         Commission  under  Section 16 of the  Exchange Act  (together  with any
         successor  rule,  "Rule  16b-3") and an "outside  director"  within the
         meaning  of  Section  162(m).  If,  however,  at least  two of  MAMSI's
         directors   are  not  both   "non-employee   directors"   and  "outside
         directors," the Board may grant Options to a key employee who is either
         a "covered  employee" or subject to Section 16 of the Exchange  Act, in
         which  case  the  Board  may  also  administer  the  Plan  and the term
         "Committee"  as used herein  shall also  include  the Board.  The other
         Committee  (the "Select  Committee")  shall be composed of at least one
         director  of MAMSI,  who may be an officer of the  Company.  The Select
         Committee  shall have  authority to grant Options to a key employee who
         is not, at the date of grant of the Option, either a "covered employee"
         as defined in Section  162(m) or subject to Section 16 of the  Exchange
         Act.

                  b. The Board may, from time to time,  appoint  members of each
         Committee  in  substitution  for  those  members  who  were  previously
         appointed and may fill vacancies, however caused, in the Committee.


<PAGE>



                  c. The Stock Option  Committee and the Select  Committee shall
         each have the power and authority to administer  the Plan in accordance
         with Section 3 with respect to particular  classes of key employees (as
         specified in Section 4(a)) and, when used herein,  the term "Committee"
         shall mean either the Stock Option Committee or the Select Committee if
         the Board  appoints more than one Committee to administer the Plan. If,
         however,  there is a conflict  between the  determinations  made by the
         Stock Option  Committee and the Select  Committee,  the  determinations
         made by the Stock Option Committee shall control.

                  d.  Except  when  the   "Committee"  is  the  "Board"  in  the
         circumstance  described  in Section  4(a),  all  determinations  of the
         Committee  shall be made by a majority vote of its members.  A majority
         of a  Committee's  members shall  constitute a quorum.  Any decision or
         determination reduced to writing and signed by all of the members shall
         be fully as  effective  as if it had been made by a majority  vote at a
         meeting  duly called and held.  The  Committee  shall also have express
         authorization to hold Committee  meetings by conference  telephone,  or
         similar   communication   equipment  by  means  of  which  all  persons
         participating in the meeting can hear each other.

and it was

         FURTHER RESOLVED, that Section 9 of the 1994 Plan be, and it hereby is,
amended to read in its entirety as follows:

                  9.       AMENDMENT AND TERMINATION.

                  a.  Amendment.   The  Board  shall  have  complete  power  and
         authority  to  amend  the Plan at any time it is  deemed  necessary  or
         appropriate;  provided,  however, that the Board shall not, without the
         affirmative  approval  of a simple  majority  of the  holders of Common
         Stock,  represented,  by person or by proxy, and entitled to vote at an
         annual or special  meeting of the  holders  of Common  Stock,  make any
         amendment that requires  stockholder  approval under  applicable law or
         rule, unless the Board determines that compliance with such law or rule
         is no  longer  desired  with  respect  to the  Plan as a  whole  or the
         provision to be amended.  No  termination or amendment of the Plan may,
         without the consent of the person to whom any Option shall  theretofore
         have been granted  under the Plan,  adversely  affect the right of such
         individual  under such Option;  provided,  however,  that the Committee
         may, in its sole and absolute  discretion,  make provision in an Option
         Agreement  for  such   amendments   that,  in  its  sole  and  absolute
         discretion, it deems appropriate.

                  b.  Termination.  The Board shall have the right and the power
         to terminate the Plan at any time. No Option shall be granted under the
         Plan after the termination of the Plan, but the termination of the Plan
         shall not have any other effect and any Option  outstanding at the time
         of the  termination  of the Plan may be amended and  exercised  and may
         vest after  termination of the Plan at any time prior to the expiration
         date of such  Option to the same  extent  such  Option  could have been
         amended  or  would  have  been  exercisable  or vest  had the  Plan not
         terminated.

and it was

         FURTHER RESOLVED, that Section 11(k) be, and it hereby is, added to the
1994 Plan in the following form:

                  k.  Compliance  with Rule  16b-3  and  Section  162(m).  It is
         intended that the Plan be applied and  administered  in compliance with
         Rule 16b-3 and with Section 162(m).  If any provision of the Plan would
         be in violation of Section 162(m) if applied as written, such provision
         shall not have  effect as  written  and shall be given  effect so as to
         comply with Section  162(m) as  determined by the Committee in its sole
         and absolute discretion.  The Board is authorized to amend the Plan and
         the Committee is authorized  to make any such  modifications  to Option
         Agreements to comply with Rule 16b-3 and Section 162(m), as they may be
         amended  from time to time,  and to make any other such  amendments  or
         modifications  deemed necessary or appropriate to better accomplish the
         purposes of the Plan in light of any amendments  made to Rule 16b-3 and
         Section 162(m).  Notwithstanding the foregoing, the Board may amend the
         Plan so that it (or certain of its  provisions)  no longer  comply with
         either  or  both  of  Rule  16b-3  or  Section   162(m)  if  the  Board
         specifically  determines  that such compliance is no longer desired and
         the  Committee  may grant  Options  that do not comply  with Rule 16b-3
         and/or  Section  162(m) if the  Committee  determines,  in its sole and
         absolute  discretion,  that it is in the  interest of the Company to do
         so.

of the  option,  either a "covered  employee"  as  defined in Section  162(m) or
subject to Section 16; and it was

Amendment of 1995 Non-Qualified Stock Option Plan

         FURTHER RESOLVED,  that Section 4 of the Mid Atlantic Medical Services,
Inc.  1995  Non-Qualified  Stock Option Plan ("1995 Plan") be, and it hereby is,
amended to read in its entirety as follows:

                  4.       COMMITTEE.  The "Committee" means a committee of the
         Board of Directors of MAMSI ("Board") as may be appointed, from time to
         time, by the Board.

                  a. The Board may appoint more than one Committee to administer
         the Plan. If it appoints more than one  Committee,  one Committee  (the
         "Stock Option  Committee") shall have the authority to grant Options to
         a key  employee  who is either,  at the date of grant of the Option,  a
         "covered employee" as defined in Section 162(m) of the Internal Revenue
         Code of 1986,  as  amended  ("Code"),  and the  regulations  thereunder
         (collectively, "Section 162(m)") or who is subject to Section 16 of the
         Securities Exchange Act of 1934, as amended ("Exchange Act");  however,
         such Committee  shall also have the authority to grant Options to other
         key employees. The Stock Option Committee shall be composed of at least
         two directors of MAMSI,  each of whom is a  "non-employee  director" as
         defined in Rule 16b-3 as  promulgated  by the  Securities  and Exchange
         Commission  under  Section 16 of the  Exchange Act  (together  with any
         successor  rule,  "Rule  16b-3") and an "outside  director"  within the
         meaning  of  Section  162(m).  If,  however,  at least  two of  MAMSI's
         directors   are  not  both   "non-employee   directors"   and  "outside
         directors," the Board may grant Options to a key employee who is either
         a "covered  employee" or subject to Section 16 of the Exchange  Act, in
         which  case  the  Board  may  also  administer  the  Plan  and the term
         "Committee"  as used herein  shall also  include  the Board.  The other
         Committee  (the "Select  Committee")  shall be composed of at least one
         director  of MAMSI,  who may be an officer of the  Company.  The Select
         Committee  shall have  authority to grant Options to a key employee who
         is not, at the date of grant of the Option, either a "covered employee"
         as defined in Section  162(m) or subject to Section 16 of the  Exchange
         Act.

                  b. The Board may, from time to time,  appoint  members of each
         Committee  in  substitution  for  those  members  who  were  previously
         appointed and may fill vacancies, however caused, in the Committee.


<PAGE>



                  c. The Stock Option  Committee and the Select  Committee shall
         each have the power and authority to administer  the Plan in accordance
         with Section 3 with respect to particular  classes of key employees (as
         specified in Section 4(a)) and, when used herein,  the term "Committee"
         shall mean either the Stock Option Committee or the Select Committee if
         the Board  appoints more than one Committee to administer the Plan. If,
         however,  there is a conflict  between the  determinations  made by the
         Stock Option  Committee and the Select  Committee,  the  determinations
         made by the Stock Option Committee shall control.

                  d.  Except  when  the   "Committee"  is  the  "Board"  in  the
         circumstance  described  in Section  4(a),  all  determinations  of the
         Committee  shall be made by a majority vote of its members.  A majority
         of a  Committee's  members shall  constitute a quorum.  Any decision or
         determination reduced to writing and signed by all of the members shall
         be fully as  effective  as if it had been made by a majority  vote at a
         meeting  duly called and held.  The  Committee  shall also have express
         authorization to hold Committee  meetings by conference  telephone,  or
         similar   communication   equipment  by  means  of  which  all  persons
         participating in the meeting can hear each other.

and it was

         FURTHER RESOLVED, that Section 9 of the 1995 Plan be, and it hereby is,
amended to read in its entirety as follows:

                  9.       AMENDMENT AND TERMINATION.

                  a.  Amendment.   The  Board  shall  have  complete  power  and
         authority  to  amend  the Plan at any time it is  deemed  necessary  or
         appropriate;  provided,  however, that the Board shall not, without the
         affirmative  approval  of a simple  majority  of the  holders of Common
         Stock,  represented,  by person or by proxy, and entitled to vote at an
         annual or special  meeting of the  holders  of Common  Stock,  make any
         amendment that requires  stockholder  approval under  applicable law or
         rule, unless the Board determines that compliance with such law or rule
         is no  longer  desired  with  respect  to the  Plan as a  whole  or the
         provision to be amended.  No  termination or amendment of the Plan may,
         without the consent of the person to whom any Option shall  theretofore
         have been granted  under the Plan,  adversely  affect the right of such
         individual  under such Option;  provided,  however,  that the Committee
         may, in its sole and absolute  discretion,  make provision in an Option
         Agreement  for  such   amendments   that,  in  its  sole  and  absolute
         discretion, it deems appropriate.




<PAGE>


                  b.  Termination.  The Board shall have the right and the power
         to terminate the Plan at any time. No Option shall be granted under the
         Plan after the termination of the Plan, but the termination of the Plan
         shall not have any other effect and any Option  outstanding at the time
         of the  termination  of the Plan may be amended and  exercised  and may
         vest after  termination of the Plan at any time prior to the expiration
         date of such  Option to the same  extent  such  Option  could have been
         amended  or  would  have  been  exercisable  or vest  had the  Plan not
         terminated.

and it was

         FURTHER RESOLVED, that Section 11(k) be, and it hereby is, added to the
1995 Plan in the following form:

                  k.  Compliance  with Rule  16b-3  and  Section  162(m).  It is
         intended that the Plan be applied and  administered  in compliance with
         Rule 16b-3 and with Section 162(m).  If any provision of the Plan would
         be in violation of Section 162(m) if applied as written, such provision
         shall not have  effect as  written  and shall be given  effect so as to
         comply with Section  162(m) as  determined by the Committee in its sole
         and absolute discretion.  The Board is authorized to amend the Plan and
         the Committee is authorized  to make any such  modifications  to Option
         Agreements to comply with Rule 16b-3 and Section 162(m), as they may be
         amended  from time to time,  and to make any other such  amendments  or
         modifications  deemed necessary or appropriate to better accomplish the
         purposes of the Plan in light of any amendments  made to Rule 16b-3 and
         Section 162(m).  Notwithstanding the foregoing, the Board may amend the
         Plan so that it (or certain of its  provisions)  no longer  comply with
         either  or  both  of  Rule  16b-3  or  Section   162(m)  if  the  Board
         specifically  determines  that such compliance is no longer desired and
         the  Committee  may grant  Options  that do not comply  with Rule 16b-3
         and/or  Section  162(m) if the  Committee  determines,  in its sole and
         absolute  discretion,  that it is in the  interest of the Company to do
         so.

After a motion was made and seconded, and with a majority of the Board voting,

     administer the Plan. If it appoints more than one Committee,  one Committee
     (the Stock Option Committee) shall have the authority to grant Options to a
     Participant  who is either,  at the Date of Grant of the Option,  a covered
     employee  as defined  in Section  162(m) or who is subject to Section 16 of
     the Exchange Act; however,  such Committee shall also have the authority to
     grant Options to other  Participants.  The Stock Option  Committee shall be
     composed  of at  least  two  directors  of the  Company,  each of whom is a
     "non-employee  director" as defined in Rule 16b-3 and an "outside director"
     within the  meaning of Section  162(m).  If,  however,  at least two of the
     Company's  directors  are  not  both  non-employee  directors  and  outside
     directors,  the Board may grant  Options to a  Participant  who is either a
     covered  employee  or subject to Section 16 of the  Exchange  Act, in which

     herein  shall also  include  the Board.  The other  Committee  (the  Select
     Committee)  shall be  composed  of at  least  one  director,  who may be an
     officer of the Company.  The Select Committee shall have authority to grant
     Options to a  Participant  who is not,  at the Date of Grant of the Option,

     Section 16 of the Exchange Act.

                  (b) The Board may, from time to time,  appoint members of each
     Committee in substitution  for those members who were previously  appointed
     and may fill vacancies, however caused, in the Committee.

                  (c) The Stock Option  Committee and the Select Committee shall
     each have the power and authority to administer the Plan in accordance with
     Article  III  with  respect  to  particular  classes  of  Participants  (as
     specified in Section  2.05(a))  and, when used herein,  the term  Committee
     shall mean either the Stock Option Committee or the Select Committee if the
     Board appoints more than one Committee to administer the Plan. If, however,
     there is a conflict  between the  determinations  made by the Stock  Option
     Committee and the Select Committee,  the  determinations  made by the Stock
     Option Committee shall control.

     in the  circumstance  described in the last sentence of Section  2.05,  all
     determinations  of the  Committee  shall be made by a majority  vote of its

     decision  or  determination  reduced  to  writing  and signed by all of the
     members  shall be fully as  effective  as if it had been made by a majority
     vote at a meeting  duly  called  and held.  The  Committee  shall also have

     Section  162(m).  If any  provision  of the Plan would be in  violation  of
     Section 162(m) if applied as written,  such provision shall not have effect
     as written and shall be given effect so as to comply with Section 162(m) as
     determined by the Committee in its sole and absolute discretion.  The Board

     necessary or appropriate  to better  accomplish the purposes of the Plan in
     light  of  any   amendments   made  to  Rule  16b-3  and  Section   162(m).

     certain of its  provisions)  no longer  comply  with either or both of Rule
     16b-3 or  Section  162(m) if the Board  specifically  determines  that such
     compliance is no longer desired and the Committee may grant Options that do
     not  comply  with  Rule  16b-3  and/or  Section  162(m)  if  the  Committee

     authority  to  amend  the  Plan  at any  time  it is  deemed  necessary  or
     appropriate;  provided,  however,  that the Board  shall not,  without  the

     requires  stockholder  approval under  applicable  law or rule,  unless the
     Board determines that compliance with such law or rule is no longer desired

     termination  or  amendment  of the Plan may,  without  the  consent  of the
     Participant  to whom any Option shall  theretofore  have been granted under
     the Plan,  adversely affect the right of such individual under such Option;

extent of Executive  participation  in the  Management  Bonus  Program  shall be
calculated in a similar manner to the bonus paid to other senior staff, but that
the  minimum  bonus  amount will equal 25 percent of that year's base salary and
the maximum amount will equal 50 percent of base salary.

were Executive=s only item of taxable income and Executive was entitled to claim
no credits with respect thereto, but such Tax Indemnity Payment shall be the net
of the  maximum  reduction  in federal  income  taxes that could be  obtained by
Executive  from  reduction of the state and local income taxes  applicable  with
respect to such amount. Upon request, the Executive shall provide to the Company
one copy of all individual  federal,  state,  and local income tax returns filed
for the year preceding  that for which the Income Tax Indemnity  Payment is due.

Company=s  Stock  Option  Committee,  with an  exercise  price equal to the fair
market value on the date of grant,  to the Executive  options to acquire 200,000
shares of Company  stock as a one time signing  bonus.  It is  anticipated  that

Stock Option Committee would grant an additional 200,000 shares in April 1998 as
the Executive annual stock option grant.

         Assuming continued performance, Executive will be granted an additional
200,000 shares with an exercise price equal to the fair market value on the date

signed statement  itemizing the expenses so incurred in accordance with policies
adopted by the Company for reimbursement of their executives.

shall on a regular basis reimburse the Executive for normal up-keep,  insurance,

business purposes of the Company or any subsidiary  company.  To the extent that
the Company  expenditures  for such  automobile are determined by the Company to
result in taxable  income to Executive,  the Company will also pay to Executive,
as an Income Tax  Indemnity  Payment,  to be computed  and paid as  described in

<PAGE>

executive employee of Company.

         6.       Death or Incapacity.

                  In the event of the  death of the  Executive  during  the term
hereof,  this Agreement  shall terminate and the Company shall not be subject to
any further  obligation  to such  deceased  Executive  hereunder,  or his estate

including  without  limitation any vested  benefits  under the Company  employee
benefit  programs  and  any  incentive  payment  which  may be due  pursuant  to
subsections 3.2 and 3.9 hereof.

duties  contemplated by this Agreement for a total of 90 days or more within any
12 consecutive  calendar months, the Company may, upon 30 days written notice to
the Executive, reassign the Executive in accordance with Section 10.

         7.       Covenant Not to Compete.

                  In carrying out his duties under this Agreement, the Executive

business  activities  of the Company  and its  subsidiaries  including,  without
limitation,  financial  projections and models,  cost and sales data,  marketing
plans  and  programs,  and  methods  of  operation.  In  order  to  protect  the
confidentiality  of information  acquired by the Executive  heretofore or in the
future in the course of his employment, the Executive hereby agrees that, during
the term of this  Agreement  and for a period of one year after any  termination
hereof,  he will not,  in any area of service  by the  Company or in any area in
which the Executive knows the Company,  or any direct or indirect  subsidiary or
affiliate  (including  but not  limited to the  Company,  or any  subsidiary  or
affiliate thereof) intends to extend its service, unless acting as an officer or
employee  of the  Company,  or with the prior  written  consent  of the Board of
Directors or the Company,  directly or indirectly manage,  operate,  control, or
own a 5 percent or more interest in or serve as an officer, director,  employee,

accordance with the amount of care actually provided. This covenant by Executive
shall be construed as an agreement  independent  of any other  provision of this
Agreement;  and the  existence of any claim or cause of action of the  Executive
against the Company or any of its subsidiaries whether or not predicated on this
Agreement,  shall not constitute a defense to the  enforceability by the Company
or any of its  subsidiaries  of this  Section 7. Any  violation  of this Section
would constitute a basis for termination with cause by the Company.

                  In  consideration  of  the  Executive=s  covenant  under  this
Section  7.1 not to compete for a period of one year after  termination  of this
Agreement,  as set forth  above,  the Company  shall  retain the  Executive as a
Consultant  for a  period  beginning  at the  conclusion  of the  term  of  this
Agreement  and not to exceed  one year.  The  Executive  shall be paid an amount
equal to the  Executive  pre-termination  base salary in  consideration  of this
covenant. The Company shall enforce this Section 7.1 through all available legal
means.

         8.       Termination.

                  Either of the employers or the  Executive  may terminate  this
Agreement in the event of a material  breach  thereof by the Executive or either
of the  employers,  respectively,  and the Executive may also be terminated  for
cause by either employer;  provided, however, that termination of this Agreement
by the  Company  for  either  material  breach  or cause  shall not  affect  any
obligation  arising under this  Agreement.  Termination by any party shall be by
notice  in  writing  specifying  such  material  breach  or cause  and  shall be
effective  on the date of such  notice,  without  prejudice to the rights of the
party to whom such notice is given to contest such  termination  by  appropriate
judicial means.



<PAGE>



                  For purposes of  termination of this Agreement by the Company,
the following  events shall be considered  cause under the preceding  subsection
8.1 for which Executive may be terminated:

         (a)  failure  or  refusal  by   Executive  to  perform  his  duties  in
              accordance with this Agreement,  including without  limitation the
              duty to keep the  Board of  Directors  of the  Company  adequately
              informed  and to  submit  to it  such  written  reports  as it may
              reasonably require;
         (b)  any material act of  self-dealing  between the  Executive  and the
              Company=s  business that is not disclosed in full to, and approved
              by, the Board of Directors of the Company;
         (c)  misrepresentation  of the  performance  and affairs of the Company
              and other matters affecting the Company;
         (d)  deliberate  falsification  by  the  Executive  of any  records  or
              reports; (e) fraud on the part of the Executive;
         (f)  theft, embezzlement, or misappropriation by the Executive of any 
              funds of the Company, or conviction of the Executive for any
              felony;
         (g)  execution  by  the  Executive  or  any  document  transferring  or
              creating any material lien or  encumbrance  on any property of the
              Company without authorization of its Board of Directors.
         (h)  such other act as should  cause  material  harm to the business or
              property of the Company unless action was taken in good faith such
              as with a reasonable belief that such act was in the best interest
              of the Company.

All  references  to the Company in this Section 8 shall be deemed to include any
parent, subsidiaries, and affiliates of the Company.

                  At the  meeting  of the  Board of  Directors  of the  Company,
occurring during the fourth quarter of each year at what has been referred to as
the Planning  Session the Board shall, in the absence of the Executive,  discuss
the Executive performance, and take an affirmative vote to retain the Executive.
Should the Executive fail to receive the  affirmative  vote of more than half of
the  Directors  present and voting,  the Executive  duties under this  Agreement
shall  terminate,  and the  Executive  shall be entitled to  compensation  in an
amount equal to that determined under Section 10 of this Agreement,  however the
Executive  stock option vesting will not accelerate as described in Section 10.3
in such a situation.

                  Executive  should have the right to terminate  the contract by
providing  to the  Board of  Directors  notice of such  termination  6 months in
advance of such  termination or such other period of time as may be agreed to by
the parties. Termination pursuant to this Section 8.4 is not considered a change
in contract and no payments  will be made under  Section 10 after such notice is
provided by Executive.

         9.       Reassignment.

                   The Company may with cause  reassign the  Executive  from the
position of chairman, president, and chief executive officer to another position
in the Company.  Upon  reassignment,  Executive shall be entitled to continue to
receive his salary and any current bonus accrued, but no incentive  compensation
unless such position to which Executive is assigned is otherwise  covered by the
Company Management Bonus Program or any subsequent  incentive program adopted by
the  Company.  Should  such  reassignment  be  unacceptable  to  the  Executive,
Executive may elect to treat such  reassignment as a change in control under the
provision of Section 10.

         10.      Change in Control.

                  For purposes of this Agreement, a Achange in control@ shall be
deemed to have occurred if, at any time (a)  substantially all the assets of the
Company have been sold or transferred by sale,  merger, or otherwise,  or if any
person (as such term is used in Sections  13(d) or 14(d) of the Exchange Act) is
or becomes the beneficial  owner,  directly or indirectly,  of securities of the
Company representing 50 percent or more of the combines voting power of the then
issued and  outstanding  securities  of the  Company;  and (b) the  Executive is
reassigned pursuant to subsection 9.1 within six months of such sale, merger, or
other event; provided, however, that no Achange in control


<PAGE>



shall be deemed to have  occurred  unless such  reassignment  is coupled  with a
significant diminution of the duties,  compensation and/or privileges previously
attaching to the Executive position as president,  chairman, and chief executive
officer of the Company. No change in control shall be deemed to have occurred if
the  reassignment   under  subsection  9.1  is  on  a  temporary  basis  and  is
attributable to the Executive  illness or other physical,  mental,  or emotional
disability or incapacity.

                  In the event of a change in control  as defined in  subsection
10.1  Executive  shall be entitled to a lump sum payment which shall be equal to
two times the Executive base salary for the year in which such change in control
occurs.  Upon payment of the lump sum provided under this  subsection  10.2, the
obligations of the Company to employ Executive under this Agreement shall cease.
However, if the event which triggers the application of this provision occurs in
calendar year 2001, the Executive shall receive, under this Section 10.2 no more
than the number of months remaining under the terms of the Agreement  multiplied
by an amount equal to two months base  salary.  Notwithstanding  the above,  the
Company shall continue to be responsible for the payment of life insurance under
Section 3.5 and payment of the Company retirement obligations under Section 3.9.

                  In the event of a change in control  as defined in  subsection
10.1, all stock options to which  Executive is entitled shall  immediately  vest
and become exercisable.  Such acceleration of the vesting of stock options shall
be in  addition  to,  and shall  have no effect on,  any  payments  pursuant  to
subsection.

                  The value of all payments,  benefits,  and other consideration
received  pursuant to subsections  10.2 and 10.3 and contingent upon a change in
control, and any additional payments in the nature of compensation  described by
Section  280G(b)(2)  of the Internal  Revenue  Code,  shall not exceed an amount
which is equal to three times the average taxable  compensation from the Company
for the base  period  as that  term is  defined  in  Section  280G(d)(2)  of the
Internal Revenue Code. The parties agree to review the impact of the termination
of this  Agreement  pursuant to Section 10, and to negotiate  modifications,  if
mutually  acceptable in situations where the results to the Executive and to the
Company are not compatible.

         11.      Notices.
