                           AMERICA SERVICE GROUP INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 1999

1.       BASIS OF PRESENTATION

The interim consolidated financial statements as of March 31, 1999 and for the
quarter then ended are unaudited, but in the opinion of management, have been
prepared in conformity with generally accepted accounting principles applied on
a basis consistent with those of the annual audited consolidated financial
statements. Such interim consolidated financial statements reflect all
adjustments (consisting of normal recurring accruals) necessary for a fair
presentation of the financial position and the results of operations for the
quarter presented. The results of operations for the three months presented are
not necessarily indicative of the results to be expected for the year ending
December 31, 1999. The interim consolidated financial statements should be read
in connection with the audited consolidated financial statements for the year
ended December 31, 1998.

2.       RECLASSIFICATIONS

Certain reclassifications have been made to the March 1998 Condensed
Consolidated Income Statement relating to the presentation of the MedPartners
Release and Settlement Agreement as discussed in Note 4. Specifically, $0.4
million of reimbursements relating to healthcare and lease costs are now
reflected in healthcare expenses and $0.7 million of costs and associated with
the failed merger are included in selling, general and administrative expenses.
The reclassifications increased the nonrecurring gain by $1.1 million to $1.6
million. The reclassifications did not impact net income or earnings per share
calculations and were discussed in conjunction with the Company's March 1998
10-Q's Management's Discussion and Analysis of Financial Condition and Results
of Operations.

3.       ACQUISITION OF GOVERNMENT SERVICES DIVISION

On January 26, 1999, the Company purchased all of the outstanding stock of EMSA
Government Services, Inc. ("EMSA") from InPhyNet Administrative Services, Inc.
("InPhyNet") for $67.0 million in cash pursuant to a Stock Purchase Agreement,
dated as of December 18, 1998 (the "Stock Purchase Agreement"), as amended by
the First Amendment to Stock Purchase Agreement, dated as of January 26, 1999
(the "First Amendment"), between the Company and InPhyNet. InPhyNet is a
wholly-owned subsidiary of MedPartners, Inc. ("MedPartners").

EMSA conducts its operations through two wholly-owned subsidiaries, EMSA
Correctional Care, Inc. and EMSA Military Services, Inc., each of which became
indirect subsidiaries of the Company pursuant to its acquisition of EMSA. EMSA
Correctional provides comprehensive managed healthcare solutions to state and
local correctional facilities, managing healthcare for approximately 70,000
inmates. Following the EMSA acquisition, the Company, through EMSA Correctional
and Prison Health Services, Inc. ("PHS"), manages healthcare for approximately



                                       6
<PAGE>   7

133,000 inmates in 25 states. EMSA Military contracts with the U.S. Department
of Defense (the "DOD") and the Veterans Administration (the "VA") to provide
emergency medicine and primary healthcare services to active and retired
military personnel and their dependents at medical facilities operated by the
DOD and the VA.

The purchase price paid to InPhyNet was subject to increase or decrease on a
dollar-for-dollar basis by an amount equal to the amount by which EMSA's working
capital, as defined, and as reflected on its balance sheet as of January 25,
1999 (the "Closing Date Balance Sheet"), was in excess of or was less than $27.6
million. The Closing Date Balance Sheet reflected working capital, as defined,
of $24.0 million. Accordingly, the Company received $3.6 million in March 1999
as part of the purchase price adjustment. The Company will account for the EMSA
acquisition using the purchase method of accounting.

In connection with the EMSA acquisition: (i) the Company and all of its
subsidiaries, including EMSA, EMSA Military and EMSA Correctional, entered into
an Amended and Restated Credit Agreement, dated as of January 26, 1999, with
NationsBank, N.A., as Administrative Agent and Issuing Bank ("NationsBank"),
which provides for a revolving credit facility of up to $52.0 million (the
"Credit Facility") through July 26, 1999, at which time availability is reduced
as defined within the Credit Facility and (ii) the Company entered into a
Securities Purchase Agreement, dated as of January 26, 1999 (the "Securities
Purchase Agreement") with Health Care Capital Partners L.P. ("Capital Partners")
and Health Care Executive Partners L.P. ("Executive Partners"), investment funds
managed by Ferrer Freeman Thompson & Co. (collectively, with Capital Partners
and Executive Partners, "FFT"). On January 26, 1999, pursuant to the Securities
Purchase Agreement, the Company issued to Capital Partners and Executive
Partners (i) $15.0 million aggregate principal amount of the Company's 12%
Subordinated Convertible Bridge Notes due January 26, 2000 (the "Notes") with
detachable warrants (the "Warrants") to purchase an aggregate 135,000 shares of
the Company's common stock, par value $0.01 per share (the "Common Stock"), and
(ii) 50,000 shares of the Company's Series A Convertible Preferred Stock, par
value $0.01 per share (the "Preferred Stock"), for $5.0 million. The Preferred
Stock is subject to mandatory redemption on July 26, 2005. The Notes, Warrants
and Preferred Stock are referred to collectively as the "Convertible Shares."

The Company used $47.0 million in borrowings under the Credit Facility and the
aggregate $20.0 million in proceeds received from its issuance of the
Convertible Securities to Capital Partners and Executive Partners to finance, in
part, the EMSA acquisition, which consisted of assets acquired of $89.2 million,
including cash of $0.9 million and $46.4 million of cost in excess of net assets
acquired and the assumption of $22.2 million in liabilities. The following
unaudited pro forma results of operations give effect to the operations of the
Company as if the acquisition had occurred effective January 1, 1999:

4.       RELEASE AND SETTLEMENT AGREEMENT

On October 1, 1997, the Company entered into a Plan and Agreement of Merger (the
"Merger Agreement") with MedPartners, Inc., a Delaware corporation
("MedPartners"), and a wholly-owned subsidiary of MedPartners, pursuant to which
the Company would have been acquired by MedPartners (the "Merger"). In
connection with the Merger, each issued and outstanding share of the Company's
Common Stock, $0.01 par value per share (the "Company's Common Stock") would
have been converted into the right to receive 0.71 of a share of MedPartners'
Common Stock. On October 28, 1997, MedPartners entered into a Plan and Agreement
of Merger (the "PhyCor Merger Agreement") with PhyCor, Inc., a Delaware
corporation ("PhyCor"), pursuant to which MedPartners would have been acquired
by PhyCor and each issued and outstanding share of MedPartners' Common Stock
would have been converted into the right to receive 1.18 shares of PhyCor Common
Stock.

The Company mailed a Proxy Statement to the holders of its Common Stock on
November 20, 1997. The Proxy Statement related to a special meeting of the
Company's stockholders scheduled to be held on December 29, 1997, for the
purpose of considering and voting upon the Merger. On December 29, the Company
postponed the special meeting at the request of MedPartners until January 20,
1998.

On January 20, 1998, the Company announced that it would not hold the special
meeting of its stockholders originally scheduled for December 29, 1997, and that
it was engaged in discussions with MedPartners regarding the Merger Agreement.
On February 26, 1998, the Company announced the termination of the Merger
Agreement and the execution of a Release and Settlement Agreement (the
"Settlement Agreement") with MedPartners relating to the Merger Agreement.
Pursuant to the Settlement Agreement, MedPartners agreed to pay the Company
approximately $3.5 million in cash and to reimburse or assume certain other
costs incurred by the Company in connection with the Merger in the amount of
approximately $2.0 million.

ITEM 2. -- MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

This quarterly report on Form 10-Q contains and incorporates by reference
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended. Those statements include, among other things, discussions of the
Company's business strategy and expectations concerning the Company's position
in the industry, future operations, margins, profitability, liquidity and



                                       8
<PAGE>   9

capital resources. All these forward-looking statements are based on estimates
and assumptions made by management of the Company that, although believed to be
reasonable, are inherently uncertain. Therefore, undue reliance should not be
placed on such statements and estimates. No assurance can be given that any of
such estimates or statements will be realized, and it is likely that actual
results may differ materially from those contemplated by such forward-looking
statements. Factors that may cause such differences include, but are not limited
to, those set forth in the Company's Annual Report on Form 10-K for the fiscal
year ended December 31, 1998 (the "1998 Form 10-K") under the heading "Item 1.
Business - Cautionary Statements," which cautionary statements are hereby
incorporated herein by reference. All forward-looking statements attributable to
the Company or persons acting on behalf of the Company are expressly qualified
in their entirety by the cautionary statements set forth in the 1998 Form 10-K.
In light of these and other uncertainties, the inclusion of forward-looking
statements herein or in any statement made by the Company should not be regarded
as a representation by the Company that the Company's plans and objectives will
be achieved.

RESULTS OF OPERATIONS

FIRST QUARTER MARCH 1999 VERSUS FIRST QUARTER MARCH 1998

Healthcare revenues for the quarter March 1999 increased to $58.3 million from
$27.6 million in the first quarter 1998. The $30.7 million increase is
attributable to both the acquisition of EMSA and an increase in inmate
population and automatic pricing adjustments of existing PHS contracts. Revenue
from EMSA was $28.4 million, while existing PHS contracts increased $2.3 million
or 8.3% as compared to March 1998.

Healthcare expenses during the first quarter 1999 were $52.5 million or 90.0% of
revenue versus $24.8 million or 89.9% of revenue for the same period in 1998.
The $27.7 million increase is mainly attributable to the EMSA acquisition.

Selling, general and administrative expenses for the quarter ended March 1999
increased $0.3 million as compared to March 1998, due to the additional costs
related to the EMSA acquisition. Selling, general and administrative expenses
for the quarter ended March 1998 include $0.7 million of costs to related the
failed merger with MedPartners. As a percent of revenue, selling, general and
administrative expenses are 5.2% for March 1999 versus 7.6% for March 1998,
exclusive of the costs associated with the failed merger. The percentage
decrease demonstrates the leverage on selling, general and administrative
expense provided by the EMSA acquisition.

Depreciation and amortization increased $0.4 million to $0.7 million for March
1999. The increase is due to the amortization of cost in excess of net assets
relating to the EMSA acquisition, which is being amortized over twenty years.

Net interest expense of $1.0 million for March 1998 relates to the financing of
the EMSA acquisition through the Senior Revolving Credit Facility of $47.0
million and the $15.0 million



                                       9
<PAGE>   10

Convertible Subordinated Notes. Interest expense of $1.1 million was offset by
$0.1 million of interest income.

Income taxes for March 1999 were $0.6 million, which equates to a 56.0%
effective tax rate. The significant effective rate is directly related to the
non-deductibility of interest related to the Convertible Subordinated Notes. The
March 1998 financial statements have no provision for income taxes due to the
utilization of income tax loss carryforwards.

The Company recorded a gain of $1.6 million in the first quarter of 1998 related
to the Settlement Agreement between the Company and MedPartners. As part of the
Settlement Agreement, the Company received payments totaling $2.2 million in
February and April 1998, of which $1.0 million reimbursed the Company for costs
directly associated with the terminated merger transaction. In addition to the
$1.2 million recognized from payments from MedPartners, an additional $0.4
million in employee healthcare and lease costs were reimbursed by MedPartners
for the quarter ended March 1998.

LIQUIDITY AND CAPITAL RESOURCES

The Company's cash, cash equivalents and short-term investments at March 31,
1999, were $1.5 million, compared with cash, cash equivalents and investments of
$7.2 million at December 31, 1998. Cash provided by operating activities during
the three months ended March 31, 1999 was $3.6 million compared to cash used in
operations of $.7 million for the comparable 1998 period. The overall increase
in cash from operating activities was due to the transitioning of corporate
finance during the first quarter, including processing of vendor and medical
claims invoices and accounts receivable. The transition delayed the processing
of both vendor and medical providers' claims, as well as billing and collections
of certain contracts' monthly base fees, whereby the net impact was to increase
cash. The decrease in cash is attributable to the paydown of $10.0 million of
the Senior Revolving Credit Facility offset by cash from operating activities.

Management believes that the current levels of cash, when coupled with
internally generated funds and the line of credit, are sufficient to meet the
Company's foreseeable cash needs.

YEAR 2000 UPDATE

The Year 2000 problem is the result of two potential malfunctions that could
have an impact on the Company's operations. The first is computer systems and
software being programmed to use two rather than four digits to define the
applicable year. The second is the use of embedded chips that have been designed
using two rather than four digits to define the applicable year. These chips are
often used in medical equipment used in certain Company sites.

The Company has completed the evaluation of all computer systems and software it
currently utilizes and has determined that 85% of all computer systems and
software will be in compliance without modification. The Company is currently in
the process of modifying or replacing the remaining 15% of its computer systems
and software. The general ledger, accounts payable and 


                                       10
<PAGE>   11

accounts receivable systems have been upgraded, tested and are in production.
Timekeeping software is currently being upgraded and is currently 87% complete.
The timekeeping upgrades will be completed by July 1, 1999. The Company's most
significant outsourcing contract is for medical claims processing and payment
and that vendor has certified that all Year 2000 modifications will be completed
by December 31, 1999.

The Company has undertaken a program to inventory, assess and correct or replace
the equipment that contains embedded chips. The Company has a plan to inventory
its sites, contact vendors, analyze information provided and replace or modify
devices or equipment that will have a direct impact on patient safety and
health. The Company anticipates completion in all material respects of this
portion of its Year 2000 assessment program by July 1999.

The Company is relying on information that is being provided by equipment and
medical device manufacturers regarding the Year 2000 compliance status of their
products. While the Company is attempting to evaluate information provided by
its present vendors, there can be no assurances that in all instances accurate
information is being provided. The Company also cannot in all instances
guarantee that the repair, replacement or upgrade of all items of equipment and
medical device systems will occur on a timely basis. Contingency planning will
be established and implemented in an effort to minimize any impact from Year
2000-related failures of such equipment. The Company anticipates its contingency
planning for this aspect of its Year 2000 assessment to be completed by July 31,
1999. Costs as a result of these types of occurrences are in the process of
being determined.

The Company has also initiated communications with suppliers and vendors whose
supplies are essential for day-to-day operations regarding their state of Year
2000 readiness. The Company is continuing its efforts to obtain such information
from all critical suppliers and vendors and feels that it will be able to
determine its vendors' status by July 31, 1999. Failure of certain suppliers and
vendors to remain in business without interruptions following December 31, 1999
could have a material impact on operations or the Company's ability to provide
healthcare services. Contingency plans may include stockpiling medical supplies
and materials, increasing inventory levels and securing alternate sources of
supply. The Company anticipates its contingency planning for this aspect of its
Year 2000 assessment to be completed by July 31, 1999. Costs as a result of
these types of occurrences are in the process of being determined.

Because the Company's physical sites are located within facilities owned and
operated by other entities whose Year 2000 readiness efforts it does not
control, there will be issues that arise which are dependent on these clients'
efforts. The Company has initiated communications with its clients on these
matters. The Company anticipates its contingency planning for this aspect of its
Year 2000 assessment to be completed by July 31, 1999 and feels costs related to
this phase will be immaterial.

The Company expects to expend approximately $0.1 million in connection with
evaluating, modifying and replacing its computer systems and software and
expects to fund such expenditures through operating cash flows. However, there
can be no guarantees that these estimates will be achieved and actual results
could differ materially from those anticipated.
