                   NOTES TO CONDENSED FINANCIAL STATEMENTS
                                JUNE 29, 1997
                                 (UNAUDITED)
                                      
1. BASIS OF PRESENTATION

The accompanying unaudited condensed financial statements have been prepared in
accordance with generally accepted accounting principles for interim financial
information and the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.
Operating results for the thirteen and twenty-six week periods ended June 29,
1997, are not necessarily indicative of the results that may be expected for
the fiscal year ending December 28, 1997.  The balance sheet at December 29,
1996, has been derived from the audited financial statements at that date but
does not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements.  For
additional information, refer to financial statements and footnotes thereto
included in the Company's annual report on Form 10-K for the year ended
December 29, 1996.

2. SHARE OWNERS' EQUITY AND EARNINGS PER SHARE

Net income per share amounts are computed based upon the weighted average
number of common shares and common share equivalents outstanding during each of
the periods presented.  In February 1997, the Financial Accounting Standards
Board issued SFAS No. 128 (Earnings per Share) which the Company is required to
adopt effective for the year ending December 28, 1997.  Had the Company adopted
SFAS No. 128 for the thirteen and twenty-six week periods ended June 29, 1997,
basic and comprehensive earnings per share would be the same as earnings per
share disclosed.

3. RELATED PARTY TRANSACTIONS

In February 1996, several shareholders of the Company sold an aggregate of
6,770,000 common shares in an underwritten public offering pursuant to a
registration rights agreement which was entered into by the Company and such
shareholders prior to the Company's initial public offering.  The offering
costs, totaling approximately $360,000, were paid by the Company and have been
classified under selling, general and administrative expenses for the
twenty-six week period ended June 30, 1996.  The Company did not receive any
proceeds from the sale of these common shares.

4. NOTES PAYABLE

In June 1997, the Company renegotiated its revolving credit facility (the
"credit facility") increasing borrowing capacity under the credit facility from
$40.0 million to $80.0 million.  Terms and conditions of the new agreement are
essentially the same as terms and conditions of the previous agreement.
Borrowings outstanding under the credit facility amounted to $21.5 million at
June 29, 1997.

               ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                                      
APAC TeleServices, Inc. provides telephone-based sales, marketing and customer
management solutions for corporate clients operating in the telecommunications,
insurance, financial services, parcel delivery, utilities and entertainment
industries throughout the United States.  The Company's client base is
comprised of large companies with growing needs for cost-effective means of
contacting and servicing current and prospective customers.   The Company has
two primary service offerings.  The Sales Solutions division provides outbound
sales support to consumers and businesses, database analysis and management,
market research, targeted marketing plan development and customer lead
generation, acquisition and retention.  The Service Solutions division provides
inbound customer service, direct mail response, "help" line support and
customer order processing.

APAC's results of operations in any single interim period should not be viewed
as an indication of future results of operations.  The Company may experience
quarterly variations in net revenue and operating income as a result of the
timing of clients' marketing campaigns and customer service programs, the
timing of additional selling, general and administrative expenses to acquire
and support such new business, and changes in the Company's revenue mix among
its various service offerings.  While the effects of seasonality on APAC's
business have been obscured by its growing net revenue, the Company's business
tends to be slower in the first and third quarters of its fiscal year due to
client marketing programs which are typically slower in the post-holiday and
summer months.

The following table sets forth income statement data as a percent of net
revenue from services provided by the Company for the thirteen and twenty-six
week periods ended June 29, 1997, and June 30, 1996.

RESULTS OF OPERATIONS

Net revenue for the quarter and six months ended June 29, 1997, increased $26.5
million or 40.7% and $68.7 million or 60.6%, respectively, compared to net
revenue in the same periods in 1996.  Net revenue for the Sales Solutions
division for the quarter and six months ended June 29, 1997, increased $15.8
million or 43.7% and $35.5 million or 57.1%, respectively, compared to the same
periods in 1996 as a result of increased call volume from new and existing
clients spread equitably over the Company's primary service industries, 
insurance, financial services and telecommunications.  The Service Solutions
division's net revenue for the quarter and six months ended June 29, 1997,
increased $10.7 million or 36.9% and $33.2 million or 65.0%, respectively,
compared to the same periods in 1996 as a result of  higher call volumes
associated with AT&T Corporation ("AT&T") inbound call activity and long-term
contracts to manage four United Parcel Services ("UPS") customer service
facilities and process customer orders for John H. Harland Company ("Harland").
Calls taken for UPS reached mature levels in the fourth quarter of 1996 while
the first half of 1997 reflects calls taken for new accounts with AT&T and
Harland which call volumes were not present a year ago.

Cost of services as a percent of net revenue increased to 72.1% in the second
quarter of 1997 compared to 70.3% in the second quarter of 1996.  For the first
six months of 1997 cost of services as a percentage of net revenue was 72.2% as
compared to 70.8% in the same period in 1996.  These increases primarily
reflect the mutual decision between UPS and the Company to change the staffing
requirements in the UPS customer service facilities.  UPS has the ability under
its facilities management agreement with the Company to determine service
levels.  During the first quarter of 1997, UPS reduced the number of billable
service representatives and support positions by approximately 20% resulting in
the Company absorbing payroll costs that otherwise would have been billed to
UPS.  The Company has taken steps to reduce payroll costs and improve margins
on the UPS contract in its third and fourth quarters of 1997 by eliminating
service representatives and other support positions.  For additional
information concerning the Company's relationship with UPS, see Other
Information on page 9.

Selling, general and administrative expenses for the quarter and six months
ended June 29, 1997, increased $3.8 million or 49.5% and $8.5 million or 61.8%,
respectively, compared to the same periods in 1996.  Selling, general and
administrative expenses as a percent of net revenue for the quarter and six
months increased to 12.4% and 12.3%, respectively, compared to 11.7% and 12.2%,
respectively, a year earlier.  The increases in expenses as a percent of
revenue is a result of growth in overhead due to continued investments in
systems and management to support the Company's increased revenue base and
expenses associated with long-term service contracts.

The $917,000 unfavorable change in interest from the first six months of 1996
to the first six months of 1997 reflects interest income earned on temporary
investments in 1996 with cash raised in the initial public offering of the
Company's common stock, compared to interest expense incurred on outstanding
borrowings in 1997 as a result of expansion of call center operations in the
fourth quarter of 1996 and the first half of 1997.

The provisions for income taxes of  $10.5 million for the six months ended June
29, 1997,  and $7.7 million for the same period in 1996 are based upon the
Company's estimated annual effective tax rate of 38.0 and 39.5%, respectively.
The decrease in the effective tax rate from 1996 to 1997 is due to tax planning
strategies initiated in the fourth quarter of 1996 which have reduced state
income taxes.

OTHER INFORMATION

UPS, the Company's largest client, was struck by the International Brotherhood
of Teamsters at 12:01 a.m. on August 4, 1997.  While the outcome of the labor
strike and negotiations at UPS is uncertain, an extended strike would have a
negative effect on the Company's revenues and earnings in its third and fourth
quarters of 1997.

In addition, the Company's second largest client, AT&T, has announced decisions
to reduce its investment in telephone-based sales and marketing for the last
half of 1997 and consolidate both its outbound and inbound teleservices
outsourcers.  While AT&T has informed APAC that the Company will remain as one
of its principal teleservices outsourcers, AT&T's cost reduction initiatives
also could have a negative impact on the Company's revenues and earnings during
the third and fourth quarters of 1997.  UPS and AT&T accounted for
approximately 50% of the Company's business in the first six months of 1997.

LIQUIDITY AND CAPITAL RESOURCES

Operations provided $15.9 million of cash in the first six months of 1997
compared to the use of $2.0 million of cash in the first six months of 1996.
Approximately 30% of the $17.9 million  increase in operating cash flow in 1997
was generated by an increase in net income, while the balance was due to higher
depreciation and related tax benefits arising from capital investment in 1996
and first six months of 1997.  Capital expenditures in the first six months of
1997 amounted to $29.9 million.  Funds used to expand call center operations
and the Company's data management systems were provided by cash from
operations, bank borrowings of $5.6 million and proceeds from the sale of $5.2
million in common stock to employees.  Investment in call center operations in
1996 of $25.2 million was funded primarily with proceeds from the sale of $20.3
million in short-term investments and liquidation of $4.2 million in cash
equivalent balances.

In June 1997, the Company amended its revolving credit facility (the "credit
facility") increasing borrowing capacity under the credit facility from $40.0   
million to $80.0 million.  The credit facility is available for general working
capital purposes and capital expenditures.  As of June 29, 1997, $21.5 million
was outstanding under the credit facility.  The Company expects that cash from
future operations and available borrowings will be sufficient to meet normal
operating needs as well as fund business growth for the balance of 1997.

FORWARD-LOOKING STATEMENTS

Statements contained herein regarding APAC's expected growth, prospective
business opportunities and future expansion plans are forward-looking
statements that involve substantial risks and uncertainties.  In accordance

not assure that the Company will generate a specific level of revenue, do not
designate the Company as the client's exclusive service provider, and are
terminable by the clients on relatively short notice.  In addition, the amount
of revenue the Company generates from a particular client generally is
dependent upon customers' interest in, and use of, the client's products or
services.  Readers are encouraged to review the section captioned "Information
Regarding Forward-Looking Statements" in its Annual Report on Form 10-K for the
year ended December 29, 1996, which describe other important factors that may
impact the Company's business, results of operations and financial condition.
