                 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                     (Unaudited)

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Condensed Consolidated Financial Statements - The condensed consolidated
     balance sheet as of March  31, 1998, the condensed consolidated statements
     of income for the three month and nine month periods ended March 31, 1998
     and 1997 and the condensed consolidated statements of cash flows for the
     nine month periods then ended have been prepared by the Company, without
     audit.  In the opinion of management, all adjustments (which include only
     normal recurring adjustments) necessary to present fairly the financial
     position, results of operations and the cash flows at March 31, 1998 and
     for the periods then ended have been made.

     Certain information and footnote disclosures normally included in financial
     statements prepared in accordance with generally accepted accounting
     principles have been condensed or omitted.  It is suggested these condensed
     consolidated financial statements be read in conjunction with the financial
     statements and notes thereto included in the Company's June 30, 1997 annual
     report to shareholders.

3.   NET INCOME PER COMMON SHARE

     In February 1997, the Financial Accounting Standards Board issued Statement
     of Financial Accounting  Standards (SFAS) No. 128, "Earnings per Share".
     This statement specifies the computation, presentation, and disclosure
     requirements for earnings per share (EPS).  This Statement is effective for
     financial statements issued for periods ending after December 15, 1997,
     including interim periods and replaces the presentation of primary EPS
     with a presentation of basic EPS.  Basic EPS excludes dilution and is
     computed  by dividing income available to common stockholders by the
     weighted-average number of common shares outstanding for the period.  The
     difference between average common shares and average common and common
     equivalent shares is the result of outstanding stock options.

Item 2.

                         MANAGEMENT'S DISCUSSION AND ANALYSIS
                   OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
                      Nine Months Ended March 31, 1998 and 1997



CHANGES IN FINANCIAL CONDITION

Working capital at March 31, 1998 was $65.5 million, up 19% from the $55.0
million at June 30, 1997.  This includes cash and cash equivalents of $15.0
million compared to $17.9 million at June 30, 1997 and accounts receivable of
$87.4 million compared to $67.0 million at June 30, 1997.  Ratios of current
assets to current liabilities and total assets to total liabilities have
decreased slightly since June 30, 1997.

The Company's primary need for working capital is to support accounts receivable
resulting from the growth in its business and to fund the time lag between
payroll disbursement and receipt of fees billed to clients.  Over the past
years, the Company has been able to support the growth in its business with
internally generated funds.  The Company's sub-supplier contracts are not
expected to burden working capital. 

On December 18, 1997 the Board of Directors declared the regular quarterly
dividend of $.08 per share payable February 13, 1998 to shareholders of record
on January 31, 1998. 

On February 19, 1998 the Board of Directors declared the regular quarterly
dividend of $.08 per share payable May 15, 1998 to shareholders of record on 
April 30, 1998.

In January 1998 the Company entered into an agreement to build a facility for
use as its corporate headquarters and its Minneapolis branch operations.  The
Company expects construction and related costs will be approximately $17,000,000
and these costs will be financed through a combination of unsecured debt and use
of cash reserves.

The Company believes funds generated from its business and current cash balances
are adequate to meet demands placed upon its resources by its operations,
capital investments and the payment of quarterly dividends.

RESULTS OF OPERATIONS

Revenues provided directly for the nine months ended March 31, 1998 were $329.3
million, an increase of 33.0% over the same period a year ago.  Approximately
64% of this increase is the result of an increase in billed hours and 36% from
increases in hourly rates.  For the three months ended March 31, 1998 revenues
provided directly were $116.3 million, an increase of 31.7% over the same period
a year ago.  Approximately 66% of this increase is the result of an increase in
billed hours and 34% from increases in hourly rates.  Revenues provided through
sub-suppliers for the nine month period and quarter ended March 31, 1998 were
$97.2 million and $33.7 million, respectively.  This represents increases of
47.4% and 32.7% over the same periods a year ago.  These increases in
sub-supplier revenues resulted almost exclusively from increases in billable
hours of service rendered to clients. 

Personnel totalled 5,250 at March 31, 1998, compared to 4,400 at March 31, 1997,
an increase of 19.3%. Substantially all of the increase consists of billable
technical staff.

Salaries, contracted services and direct charges, which represent primarily the
Company's direct labor cost, were 77.9% of revenues for the nine months
ended March 31, 1998 compared to 77.3% for the same period a year ago.  These
costs were 78.2% of revenues for the three months ended March 31, 1998 and 77.6%
of revenues for the three months ended March 31, 1997.  The increase in this
expense category as a percentage of revenue is mostly a consequence of the
increase in business done through sub-suppliers, whose labor costs are higher
per hour than the labor costs of the Company's own employees.  The Company's
efforts to control these costs involve controlling labor costs, passing on labor
cost increases through increased billing rates where possible, and maintaining
productivity levels of its billable technical staff.  Labor costs, however, are
difficult to control because the highly skilled technical personnel the Company
seeks to hire and retain are in great demand and intense competition in the
industry makes it difficult to pass cost increases on to customers, while
unfavorable economic conditions could adversely affect productivity.  Although
the Company has taken steps to control this category of expense, there can be no
assurance the Company will be able to maintain or improve this level. 

Selling, administrative and other operating costs, which include commissions,
employee fringe benefits and location costs, represented 16.1% of revenues for
the nine months ended March 31, 1998 compared to 16.6% for the same period a
year ago. These costs were 15.9% of revenues for the three months ended March
31, 1998 and 16.5% of revenues for the three months ended March 31, 1997.  While
the Company has been successful in controlling selling, administrative and other
operating costs and is committed to careful cost management, there can be no
assurance the Company will be able to maintain these costs at their current
relationship to revenues.

Net income for the nine months ended March 31, 1998 increased 33.6% over the
same period a year ago.  As a percentage of revenue, net income has decreased
from 3.8% for the nine months ended March 31, 1997 to 3.7% for the nine months
ended March 31, 1998.  Net income, as a percentage of revenue, was 3.7% for the
quarters ended March 31, 1998 and 1997.  The Company's net income as a
percentage of revenues provided directly was 4.8% for the nine months ended
March 31, 1998 and 1997.  The Company's net income as a percentage of revenues
provided directly for the three months ended March 31, 1998 and 1997 was 4.8%
and 4.7%, respectively.
