                NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                    (UNAUDITED)

                                  OCTOBER 31, 1998

1.   ACCOUNTING POLICIES

     The Company's unaudited condensed consolidated financial statements have
     been prepared by the Company in accordance with generally accepted
     accounting principles for interim financial reporting and the regulations
     of the Securities and Exchange Commission for quarterly reporting. 
     Accordingly, they do not include all information and footnotes required by
     generally accepted accounting principles for complete financial statements.
     In the opinion of the Company, the statements include all adjustments,
     consisting only of normal recurring adjustments, which are necessary for a
     fair presentation of the financial position, results of operations and cash
     flows for the interim periods.  Operating results for the nine month period
     ended October 31, 1998 are not necessarily indicative of the results that
     may be expected for the year ending January 31, 1999.  Seasonal
     fluctuations in sales of the Company's products result primarily from the
     purchasing patterns of individual consumers during the Christmas holiday
     season.  These patterns tend to moderately concentrate sales in the latter
     half of the year, particularly in the fourth quarter.  For further
     information, refer to the financial statements and footnotes thereto
     included in the Company's Annual Report to Stockholders for the year ended
     January 31, 1998.  

2.   PRINCIPLES OF CONSOLIDATION

     The unaudited condensed consolidated financial statements include the
     accounts of all subsidiaries.  All intercompany accounts and transactions
     have been eliminated upon consolidation.

3.   MERGER

     On June 27, 1997, the Company completed a merger in which the Company
     acquired all of the outstanding shares of Audio King Corporation ("Audio
     King").  Audio King, a consumer specialty electronics company, operated 11
     retail stores; eight in Minnesota, two in Iowa and one in South Dakota.
     The purchase price consisted of $2.5 million in cash, 986,432 shares of
     Ultimate's common stock valued at $2.6 million, assumed debt of $7.2
     million, and other expenses and severance costs of $1.2 million.  The
     transaction was accounted for as a purchase, whereby the purchase price has
     been allocated to the acquired assets and liabilities based on estimated
     fair value at the acquisition date.  The transaction resulted in the
     Company recording goodwill in the amount of $2.5 million.  The results of
     operations since the acquisition date are included in the accompanying
     condensed consolidated financial statements.

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

Management's discussion and analysis of financial condition and results of 
operations and the financial statements and accompanying notes contain 
forward-looking information which is subject to risks and uncertainties that 
may cause future results to vary materially.  Such information includes 
reference to future profitability and steps being taken to achieve that 
result.   Factors that may cause these results not to be achieved include, 
without limitation, risks regarding increases in promotional activities of 
competitors, changes in consumer buying, the presence or absence of new 
products or product features in the Company's merchandise categories, changes 
in the distribution strategy of the Company's vendors, changes in vendor 
support for advertising and promotional programs, changes in the Company's 
merchandise sales and mix as well as general economic conditions.  Please 
refer to a discussion of these and other factors in the Company's Annual 
Report on Form 10-K for the year ended January 31, 1998 and other filings 
with the Securities and Exchange Commission.  The Company disclaims any 
intent or obligation to update publicly these forward-looking statements, 
whether as a result of new information, future events or otherwise.

RESULTS OF OPERATIONS

Net sales for the three months ended October 31, 1998 decreased 3% to $79.4 
million from $82.0 million for the three months ended October 31, 1997.  The 
sales decrease was the result of the Company's previously announced plan to 
reduce its mix of computer products.  This planned reduction of computer 
hardware selection to one computer vendor and one printer vendor resulted in 
significantly lower computer sales.  Excluding the computer category, sales 
increased by 4% for the quarter over the same period in the prior year.  Net 
sales for the nine months ending October 31, 1998 increased 11% to $221.5 
million from $199.4 million for the nine months ended October 31, 1997.  The 
increase in sales for the nine months was due primarily to the acquisition of 
Audio King effective June 27, 1997.  Sales of comparable stores were down 3% 
and 7%, respectively, for the  quarter and nine months ended October 31, 
1998. Excluding the computer category, comparable store sales were up 4% for 
the quarter and decreased 2% for the nine months ended October 31, 1998.    

Gross profit for the three months ended October 31, 1998 increased 7% to 
$24.4 million (30.7% of net sales) from $22.9 million (27.9% of net sales) 
for the three months ended October 31, 1997.  Gross profit for the nine 
months ended October 31, 1998 increased 19% to $64.6 million (29.1% of net 
sales) from $54.2 million (27.2% of net sales) for the nine months ended 
October 31, 1997.  During the quarter, sales of higher margin products in the 
Company's core categories of audio, television and mobile electronics 
contributed to the increase in gross margins.    

Selling, general and administrative expenses for the three months ended 
October 31, 1998 decreased to $21.5 million (27.0% of net sales) from $21.9 
million (26.8% of net sales) for the same period in the prior year and down 
from 29.0% of sales for the second quarter ended July 31, 1998.  Selling, 
general, and administrative expenses for the nine months ending October 31, 
1998 increased to $62.8 million (28.3% of net sales) from $52.7 million 
(26.4% of net sales) for the nine months ended October 31, 1997.  Selling, 
general and administrative expenses for the nine months were impacted by 
higher store and advertising expenses associated with the Company's strategic 
initiatives to increase the sales in the stores acquired through the Audio 
King merger.

As a result of the foregoing, income from operations increased to $3.0 
million (3.7% of net sales) for the three months ended October 31, 1998, 
compared to income from operations of $927,000 (1.1% of net sales) for the 
three months ended October 31, 1997.  Income from operations was $1.7 million 
(0.8% of net sales) for the nine months ended October 31, 1998 compared to 
income from operations of $1.5 million (0.8% of net sales) for the nine 
months ended October 31, 1997. 

Interest expense decreased to $1.0 million for the three months ended October 
31, 1998 from $1.1 million for the three months ended October 31, 1997, 
primarily due to lower amounts outstanding under the Company's revolving line 
of credit.  Interest expense increased to $3.2 million for the nine months 
ended October 31, 1998

from $2.9 million for the nine months ended October 31, 1997 due to the 
additional borrowings required as a result of the acquisition of Audio King. 

LIQUIDITY AND CAPITAL RESOURCES

Historically, the Company's primary sources of liquidity for funding 
expansion and growth have been net cash from operations, revolving credit 
lines, term loans and issuance of common stock. The Company's initial public 
offering in October 1993 resulted in proceeds of $17.8 million (net of all 
offering costs).  The Company completed a second offering of its common stock 
in November 1995 and received net proceeds of $12.5 million (net of all 
offering costs).  With the addition of Audio King, the Company now operates a 
total of 30 stores in nine states.  

In March 1995, the Company received proceeds of $12.3 million (net of the 
underwriting discount and other associated costs) from the sale of $13.0 
million aggregate principal amount of 10.25% First Mortgage Bonds (the "Bond 
Offering").  The proceeds of the Bond Offering were used to fund a 
substantial portion of the construction of the Company's warehouse, office, 
service and store facility in Thornton, Colorado (the "Thornton Facility"). 
Interest on the bonds accrues at the rate of 10.25% per year until maturity 
or earlier redemption.  The Company is required to redeem $3.25 million 
aggregate principal amount of the bonds annually (reduced to the extent of 
the bonds previously purchased or redeemed by the Company) on January 31, 2002 
and on January 31 of each of the three years thereafter, at a redemption 
price equal to par plus accrued interest to the date of redemption.  The 
bonds are not redeemable prior to March 31, 2000 and are secured by the 
Thornton Facility. 

Net cash provided by operations was $6.2 million for the nine months ended 
October 31, 1998 compared to $4.6 million for the nine months ended 
October 31, 1997.

The Company intends to continue its expansion into select metropolitan areas 
in the Rocky Mountain, Midwest and Southwest regions with its larger format 
stores.  The Company has begun analyzing new store opportunities in existing 
markets to replace some of the Company's smaller locations.  The Company 
completed the conversion of its County Line store from an outlet store to a 
regular store on September 4, 1998.  The Company expects to relocate and 
expand two to five of its locations within the next three years along with 
the possibility of adding new stores.  At the present time, no firm 
commitments for relocated or new stores have been made.  The Company 
currently anticipates these events to occur after fiscal 1999.  The size of 
these future stores is anticipated to be approximately 24,000 to 36,000 
square feet at a projected cost of $30 to $55 per square foot.  The inventory 
requirement for the Company's new larger format stores averages approximately 
$1.8 million per store, approximately $900,000 of which is financed through 
credit. 

The Company's primary capital requirements are directly related to 
expenditures for new store openings and the remodeling and upgrading of 
existing store locations.  With the exception of the Thornton Facility, all 
stores are leased.  Capital expenditures to relocate and expand existing 
stores are expected to average $1.3 million per store, excluding preopening 
expenses averaging $250,000.  Preopening costs include such items as 
advertising prior to opening, recruitment and training of new employees and 
any costs of early termination of store leases.  

On September 30, 1998, the Company executed a new three year $40 million 
credit agreement with Foothill Capital Corporation (a wholly owned subsidiary 
of Norwest Bank).  This new facility replaced the Company's $35 million line 
of credit with Norwest Bank Colorado, N.A.  Borrowings under the Company's 
new revolving line of credit are limited to the lesser of $40 million or 80% 
of eligible inventory and a portion of accounts receivable. Borrowings bear 
interest, payable monthly, based on a blend of LIBOR plus 2.0% or Norwest 
Bank's prime rate minus 3/8%.  Borrowings under this credit facility in the 
amount of $24.0 million were outstanding as of October 31, 1998.  Borrowings 
are secured by inventories, accounts receivable, equipment and intangibles.  
The Company was in compliance with all borrowing covenants at October 31, 1998.

The Company believes that its cash flow from operations and borrowings under 
its new credit facility will be sufficient to fund the Company's operations 
and debt repayment for fiscal 1999.

To fund the capital requirements for its anticipated expansion plans beyond 
fiscal 1999, the Company may be required to seek additional financing, which 
may take the form of expansion of its new credit facility, or possibly 
additional debt or equity financings.  There can be no assurance that the 
Company will be able to obtain such funds on favorable terms, if at all.

SEASONALITY

The Company's business is affected by seasonal consumer buying patterns. As 
is the case with many other retailers, the Company's sales and profits have 
been greatest in the fourth quarter (which includes the holiday selling 
season).  Operating results are dependent upon a number of factors, including 
discretionary consumer spending, which is affected by local, regional or 
national economic conditions affecting disposable consumer income, such as 
employment, business conditions, interest rates and taxation.  The Company's 
quarterly results of operations may fluctuate significantly as a result of a 
number of factors, including the timing of new or relocated and expanded 
store openings and related expenses, the success of new stores and the impact 
of new stores on existing stores, among others.  As the Company has opened 
additional stores or relocated and expanded stores within markets it already 
serves, sales at existing stores have been adversely affected.  Such adverse 
effects may occur in the future.  The Company's quarterly operating results 
also may be affected by increases in merchandise costs, price changes in 
response to competitive factors, new and increased competition, product 
availability and the costs associated with the opening of new stores.

YEAR 2000 ISSUE

Until recently most computer programs were written to store only two digits 
of date related information in order to more efficiently handle and sort 
data.  As a result, these programs were unable to properly distinguish 
between dates occurring in the year 1900 and dates occurring in the year 
2000.  This is referred to as the "Year 2000 Issue".  During fiscal 1999, the 
Company has begun to review all applications and equipment to evaluate the 
Company's exposure to the Year 2000 Issue.  The required modifications to 
existing systems have been identified and plans have been developed for 
upgrades or remediation.  The Company anticipates that the upgrades and 
remediation will be completed by August 31, 1999.  The Company's primary 
information system software is provided by Tyler Retail Systems, Inc. 
("Tyler") of Clearwater, FL.  This software operates the vast majority of the 
Company's systems and has been evaluated for Year 2000 compliance.  Tyler has 
assured the Company that the software version currently in use by the company 
will be Year 2000 compliant during the first quarter of 1999.  The Company 
believes that no significant modifications to the Tyler software will be 
necessary.  The Company's system review also identified that some older 
hardware and software may not currently be Year 2000 compliant.  These items 
are few in number and will be replaced on an accelerated basis to ensure Year 
2000 compliance.  In the opinion of the Company, costs of these upgrades are 
not material to the financial condition or operation of the Company.  The 
Company is also in communication with third parties with whom it does 
significant business in order to assess their Year 2000 compliance and 
minimize the potential for adverse consequences, if any, that could result 
from failure of such entities to address this issue.  Year 2000 issues do 
present risks that are outside of the control of the Company, including but 
not limited to, the failure of utility companies to provide electricity, the 
failure of telecommunications companies to provide voice and data transfer 
services, the failure of financial services companies to process transactions 
or transfer funds, and the failure of third party vendors or suppliers to 
become Year 2000 compliant. The Company can make no assurances that Year 2000 
issues will not have an adverse effect on the Company's business, financial 
condition, or future operations.
