NOTE C - CREDIT FACILITY

During July 1998, the Company entered into an agreement with a three bank
syndicate for an increased credit facility of $32,000.  The credit facility
provided $12,500 of term notes and up to $19,500 of revolving credit.  All debts
outstanding as of June 30, 1998 were repaid with proceeds from the new facility.
This new facility is for a three-year term and is secured by substantially all
of the assets of the Company.  Availability of funds under the new facility is
based on a multiple of trailing EBITDA.  As of March 31, 1999, the Company had
$3,649 of additional available credit.

ITEM 2.  MANAGEMENT'S DISCUSSION OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
(dollars in thousands)

Results of Operations - First Quarter 1999 as Compared to First Quarter 1998

Revenues for the first quarter of 1999 decreased $1,134, or 6%, from $18,476 in
the first quarter of 1998 to $17,342 in the first quarter of 1999.  Included in
revenues are certain costs, which are passed through to clients.  The nature of
client assignments in the first quarter of 1999 resulted in a lower level of
such costs than in the first quarter of 1998.  These pass-through costs were
$1,834 in the first quarter of 1999 and $3,657 in the first quarter of 1998.

Gross profit for the three months ended March 31, 1999 was $7,244, an increase
of $301, or 4%, over the same period in 1998.  The gross profit increase is
consistent with the revenue increase net of pass-through costs.

Selling, general and administrative expenses decreased to $4,791 from $4,892 for
the three months ended March 31, 1999 relative to the same period in 1998.  This
reflects cost reduction initiatives throughout the Company and a net cost
reduction in the Teleservices business segment ("Teleservices") resulting from
the opening of a new call center in 1999 and the closure of a call center in
1998.

Depreciation and amortization expense increased to $1,015 from $918 for the
three months ended March 31, 1999, relative to the same period in 1998.  $54 of
the increase is due to additional goodwill amortization on a $3,000 acquisition
payment in Teleservices; the remainder is principally due to the depreciation of
new capital investments made in 1998 and the first quarter of 1999.

Interest expense increased to $424 from $361 for the three months ended March
31, 1999 relative to the same period in 1998, primarily due to the increased
borrowing to fund the Teleservices acquisition in January 1998 and subsequent
earn-out payments in the first quarter of 1999.

As a result of all of the above, net income for the Company increased from $425
to $552 for the three months ended March 31, 1998 and 1999, respectively.

Liquidity and Capital Resources

Net cash used by operations for the first three months of 1999 was $1,378.
Included in the current period were payments of $1,948 related to the unusual
charge of $2,470 recorded in the fourth quarter of 1998 in relation to a
separation agreement with the Company's former Chairman and CEO and the buy-out
of his pre-existing employment contract.

Investing and financing activities for the first three months of 1999 included
capital expenditures of $1,109 and payments of $3,000 to the principals of an
acquired Teleservices business based on 1998 operating performance.  The Company
believes that 
<PAGE>
 
its current sources of liquidity and capital will be sufficient to fund its 
long-term obligations and working capital needs for the foreseeable future.

During July 1998, the Company entered into an agreement with a three bank
syndicate for an increased credit facility of $32,000.  The credit facility
provided $12,500 of term notes and up to $19,500 of revolving credit.  All debts
outstanding as of June 30, 1998 were repaid with proceeds from the new facility.
This new facility is for a three-year term and is secured by substantially all
of the assets of the Company.  Availability of funds under the new facility is
based on a multiple of trailing EBITDA.  As of March 31, 1999, the Company had
$3,649 of additional available credit.

On April 30, 1999, the Company signed a definitive agreement to acquire Macro
International, Inc.  Closing is expected in the second quarter of 1999.

Readiness for Year 2000

The Year 2000 issue concerns the inability of some computer hardware and
software to distinguish between the year 1900 and the year 2000.  If not
corrected, the potential exists for computer system failures or miscalculations.

The Company uses computer systems in many aspects of its business, and Year 2000
problems in such systems, if not corrected, could disrupt operations and have an
adverse impact on the Company's operating results.  The Company is also exposed
to the risk that one or more of its vendors or service providers could
experience Year 2000 problems that impact the ability of such vendor or service
provider to provide goods and services.  To date, the Company is not aware of
any vendor or service provider Year 2000 issue that would have a material
adverse impact on the Company's operations.

The implementation of Year 2000 compliance procedures at the Company has
consisted of: compiling information as to the information technology (IT) and
non-IT systems that are sensitive to the Year 2000 problem; coordinating with
clients, vendors, service providers, and other third parties who are affected
by, or may affect, the Company's plans to address the Year 2000 issue.
Additionally, analysis of critical systems to determine which systems are not
Year 2000 compliant and evaluating the costs to repair or replace those systems
have been undertaken by the Company.  As potential problems are identified,
affected programs have been modified, or are in the process of being modified by
the Company's system support group to ensure future compliance.

The Company intends to complete the testing of Year 2000 compliance of its
critical systems by the end of May 1999, and of the non-critical systems by July
31, 1999.  Incremental out-of-pocket costs incurred through March 31, 1999 have
not been significant.  The Company estimates that no more than $250 will be
needed to modify or replace its existing software and hardware in order to be
Year 2000 compliant.  All maintenance and modification costs are expensed as
incurred, while the costs of new systems are being capitalized according to
generally accepted accounting principles.
<PAGE>
 
Based upon its analysis to date, management believes that the Company will be
able to continue operations in the year 2000 and beyond without a material
adverse effect caused by the Year 2000 problems.  However, the Company may
identify unidentified problems during its Year 2000 readiness assessment that
could result in such an effect.  A worst case scenario resulting from one or
more of the Company's systems being non-compliant might be an inability to
service one or more of our clients until such problem was corrected.  The
Company believes that such Year 2000 difficulties experienced by the Company
would be isolated in nature and will not have a material adverse effect on the
Company's operations.
