              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.   FINANCIAL STATEMENTS

     The accompanying unaudited condensed consolidated financial statements have
     been prepared in accordance with generally accepted accounting principles
     for interim financial information, 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 quarter and six months ended December 31, 2000 are not necessarily
     indicative of the results that may be expected for the fiscal year ending
     June 30, 2001. For further information, refer to the consolidated financial
     statements and footnotes thereto included in the Company's Annual Report on
     Form 10-K for the year ended June 30, 2000.


2.   BASIS OF PRESENTATION

     The condensed consolidated financial statements include the accounts of the
     Company and its wholly-owned subsidiaries. All significant intercompany
     balances, transactions and stockholdings have been eliminated.

     Certain prior year balances have been reclassified to conform to the
     current year presentation and restated to reflect the contract
     manufacturing business as discontinued operations.


3.   DISCONTINUED OPERATIONS

     On October 25, 1999 (the measurement date), the Company announced the
     closing of its pinball and cabinets segment. Accordingly, this segment is
     accounted for as a discontinued operation in the accompanying condensed
     consolidated financial statements.

     Manufacturing activities for the pinball and cabinets segment were
     completed by January 2000. Sales of the pinball and cabinets segment were
     nil and $2.4 million in the quarter and six months ending December 31,
     2000, respectively, and $5.5 million and $13.9 million in the quarter and
     six months ending December 31, 1999, respectively. At December 31, 2000,
     the assets of the pinball and cabinets segment had been liquidated and all
     estimated liabilities had been settled, resulting in a pre-tax reversal of
     reserves for costs related to discontinuance of such operations of $2.5
     million.

     On August 10, 2000 (the measurement date), the Company announced the
     closing of its contract manufacturing segment. Accordingly, this segment is
     accounted for as a discontinued operation in the accompanying condensed
     consolidated financial statements. Manufacturing activities for the
     contract manufacturing segment were completed by September 2000. Any
     remaining assets, including inventory and equipment, are expected to be
     sold or disposed of at the earliest practical date.

     Sales of the contract manufacturing segment were nil and $1.0 million in
     the quarter and six months ending December 31, 2000, respectively, and $3.0
     million and $6.2 million in the quarter and six months ending December 31,
     1999, respectively. At December 31, 2000, the assets of the contract
     manufacturing segment consisted of trade receivables, inventories, plant
     and equipment amounting to $0.2 million after deducting an allowance of
     $1.6 million for write-offs to estimated realizable value.

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

As used in this quarterly report on form 10-Q, the terms "we", "us", "our" and
"WMS" mean WMS Industries Inc., a Delaware corporation, and its subsidiaries,
unless the context indicates a different meaning, and the term "common stock"
means our common stock, $0.50 par value per share.

This report contains certain forward looking statements concerning our future
business conditions and outlook based on currently available information that
involves risks and uncertainties. Our actual results could differ materially
from those anticipated in the forward looking statements as a result of these
risks and uncertainties, including, without limitation, the financial strength
of the gaming industry, the expansion of legalized gaming into new markets and
legislative and regulatory changes in existing gaming markets, the development,
introduction and success of new games and new technologies and the ability to
maintain the scheduling of such introductions, our ability to qualify for and
maintain gaming licenses and approvals and other risks more fully described
under "Item 1. Business - Risk Factors" in our Annual Report on Form 10-K for
the year ended June 30, 2000.

SIGNIFICANT EVENTS AND TRENDS

In August 2000, we announced the operations of our contract manufacturing
segment were being discontinued. We completed the windup of this segment in the
second quarter of fiscal 2001. In the fourth quarter of fiscal 2000, we recorded
a $2.8 million pre-tax loss on disposal, including cash expenses of $1.2 million
for severance pay and shut down expenses. We do not anticipate that this
discontinued operation will have a material effect on our liquidity or
operations in future periods. The loss on disposal included about $1.6 million
in non-cash losses from write-downs of receivables, inventory, plant and
equipment to net realizable value. Tax benefits related to the loss on disposal
were estimated to be $1.1 million. The exact amount of the proceeds received and
the loss ultimately recorded will depend upon several factors over the course of
the shut-down period and at the date the sale of the remaining assets is
consummated. Our consolidated financial statements have been restated to reflect
the contract manufacturing segment as a discontinued operation.

In August, 2000, we announced that we would convert our 131,000 square foot
corporate headquarters and manufacturing facility in Chicago to a creative
technology campus where we will conduct all engineering, graphic design and game
development functions. Our corporate headquarters and manufacturing operations
were relocated to our Waukegan, Illinois facility during the December 2000
quarter. We also consolidated our regional warehouses. We anticipate recording
total relocation related charges of $0.07 to $0.09 per diluted share during
fiscal 2001, of which $0.01 was incurred in the September 2000 quarter and
$0.05 was incurred in the December 2000 quarter.

The California marketplace for gaming machines opened in May 2000. In the
December 2000 quarter we received a sales order representing our 3,000th gaming
machine for placement in California. As of December 31, 2000, we had over 300
participation games installed in California.

In the September 2000 quarter, we introduced JUMBLE(R), the first game in our
new Puzzle Pays(TM) series of participation games that will also include
SCRABBLE(R) and PICTIONARY(R). By December 31, 2000, we had received regulatory
approvals for JUMBLE in all major North American gaming jurisdictions. As of
December 19, 2000, the total installed base of JUMBLE exceeded 1,000 units.

LIQUIDITY AND CAPITAL RESOURCES

We believe that cash and cash equivalents and short-term investments of $85.8
million at December 31, 2000, along with the $25.0 million bank revolving line
of credit that extends to August 1, 2001, the $2.0 million bank revolving line
of credit that extends to August 1, 2002, and cash flow from operations will be
adequate to fund the anticipated level of capital expenditures, cash invested in
gaming machines on participation or lease, and increases in the levels of
inventories and receivables required in the operation of our business.

Cash provided by operating activities before changes in operating assets and
liabilities was $34.2 million for the first six months of fiscal 2001, as
compared to cash provided of $6.2 million in the comparable period of fiscal
2000. The current period's increase in cash provided from operations before
changes in operating assets and liabilities relative to the comparable prior
year's period was due to increased net income in the current period and the
litigation settlement payment of $27.0 million that we made in the previous
period.

The changes in operating assets and liabilities resulted in $19.7 million of
cash outflow for the six months ended December 31, 2000, compared with a cash
outflow of $8.0 million during the comparable prior year period. Cash outflow
for the six months ended December 31, 2000 was primarily due to an increase in
receivables, inventories and current income tax payments, offset, in part, by an
increase in accounts payable from the comparable balances at June 30, 2000. The
increase in accounts receivable is due to significant shipments made in the last
month of the quarter, increased sales volume and higher participation and lease
revenues as compared to the prior year's quarter. We have not experienced
significant bad debt expense in any of the periods represented. The increase in
inventories is due to building a safety stock of finished goods to ensure we
were able to meet customer demand during our relocation to Waukegan, Illinois.
The increase in accounts payable was related to the increase in inventories. The
cash outflow for the six months ended December 31, 1999 was primarily due to an
increase in receivables and inventories offset, in part, by an increase in
accounts payable from the comparable balances at June 30, 1999.

Cash used by investing activities was $32.0 million for the six months ended
December 31, 2000, compared with cash used of $31.0 million for the comparable
prior year period. Cash used for the purchase of property, plant and equipment
for the six months ended December 31, 2000 was $1.5 million compared with $1.8
million for the comparable prior year period. Cash used for additions to gaming
machines on participation or lease was $12.6 million and $5.4 million for the
six months ended December 31, 2000 and 1999, respectively. The increase in the
six months ended December 31, 2000 resulted from an increase of 1,312 units on
participation or lease from June 30, 2000 to December 31, 2000. Net cash of
$17.9 million was used for the purchase of short-term investments for the six
months ended December 31, 2000 compared with $23.8 million used for the purchase
of short-term investments during the comparable prior year period.

Cash provided by financing activities, which was from the exercise of common
stock options, was $3.7 million for the six months ended December 31, 2000
compared with $1.0 million for the prior year's six month period due to a
greater number of option exercises.

For the six months ended December 31, 2000, the discontinued pinball and
cabinets segment provided $0.3 million of cash, and the contract manufacturing
segment provided $0.7 million of cash. For the six months ended December 31,
1999, the pinball and cabinets segment used $4.7 million of cash, and the
contract manufacturing segment provided $1.1 million of cash.


RESULTS OF OPERATIONS

THREE MONTHS ENDED DECEMBER 31, 2000 COMPARED WITH
THREE MONTHS ENDED DECEMBER 31, 1999

Consolidated revenues increased 30.1% to $67.4 million in the quarter ended
December 31, 2000 from $51.8 million in the quarter ended December 31, 1999.
Total revenue increased $15.6 million: $10.8 million from increased machine
sales and $4.8 million from increased participation and lease revenue. We
shipped 5,004 video and reel-type gaming devices in the current quarter,
resulting in product and parts sales of $45.6 million versus 4,301 gaming
devices and $34.8 million of product and parts sales in the comparable prior
year quarter due to the continued market acceptance of new models and the impact
of the opening of the California market. In addition, the average sales price
increased from $7,618 in the prior year's quarter to $8,332 in the current
year's quarter primarily due to a price increase implemented in August 2000 and
a change in sales mix to higher priced products.



                                       8
<PAGE>   10

The increase in participation and lease revenue was due to an increase in the
installed base of participation gaming devices for which we had a total of 5,268
units installed at December 31, 2000, compared to 3,518 units installed at
December 31, 1999. The installed base increased due to continued growth in
MONOPOLY(R) brand games and the rollout of the newly introduced
JUMBLE brand game in the December 2000 quarter. Average net win per day for
participation machines decreased from $45.76 in the December 1999 quarter to
$42.98 in the December 2000 quarter. This decrease resulted primarily from the
impact of first introducing JUMBLE in the state of Nevada, which accounted for a
majority of the JUMBLE revenues in the December 2000 quarter, and which, in our
experience, has the lowest average daily rate of any domestic gaming
jurisdiction.

Consolidated gross profit in the quarter ended December 31, 2000 rose 34.3% to
$38.2 million from $28.5 million in the quarter ended December 31, 1999. The
gross margin percentage increased from 54.9% in the quarter ended December 31,
1999 to 56.7% in the quarter ended December 31, 2000. The increase in gross
margin resulted from higher gross profit margins on machine sales, partially
offset by lower gross profit margins on participation and lease revenues. The
gross margin on gaming machine sales increased from 37.9% in the December 1999
quarter to 42.4% in the December 2000 quarter due mainly to increased average
sales prices. The gross profit margin on participation and lease revenues
decreased from 89.6% to 86.6% due to a lower average net win per day for
participation devices coupled with a government mandated decrease in the net win
percentage earned on our video lottery terminals placed in Rhode Island and
Delaware.

Research and development expenses increased $1.6 million, or 63.9%, in the
current quarter to $4.1 million from $2.5 million in the quarter ended December
31, 1999 as we continued to invest in enhancing our product pipeline and product
platform. The increase was primarily due to higher engineering expenditures,
including costs to adapt our games for distribution to international markets.

Selling and administrative expenses increased 18.4% from $11.2 million in the
prior year's quarter to $13.2 million in the current year's quarter as we
increased our cost structure to support our revenue growth.

Corporate relocation expenses of $2.5 million, or $0.05 per diluted share, in
the current year's quarter represent costs associated with the relocation and
centralization of our corporate headquarters, manufacturing, distribution and
warehousing facilities to Waukegan, Illinois. Of the relocation expenses, $2.0
million, or $0.04 per diluted share, was for non-cash charges related to the
writedown of facilities and equipment. These unusual charges are expected to be
partially offset by greater productivity and operating cost efficiencies
realized upon the completion of the relocation. We anticipate total charges
associated with this relocation in the current fiscal year to approximate $0.07
to $0.09 per diluted share.

Depreciation and amortization, which includes amortization of gaming machines
under participation and lease, increased during the current year's quarter to
$4.4 million from $3.8 million in the prior year's quarter due to the increase
in the installed base of participation machines. The average installed base was
4,784 units for the December 2000 quarter, compared to 3,371 units for the
December 1999 quarter.

Operating income was $14.0 million in the current year's quarter, compared to
operating income of $24.2 million in the prior year's quarter. The decrease was
a result of the $13.2 million gain due to the reversal of the excess accrual due
to settlement of litigation in the prior year's quarter, partially offset by
higher revenues and margins in the current year's quarter. In addition, the
financial results of the current year's quarter reflect the pre-tax charge of
$2.5 million from the costs associated with our relocation and centralization of
corporate offices, manufacturing, distribution and warehousing facilities to
Waukegan, Illinois. Operating income, prior to unusual items in both periods,
was $16.5 million in the December 2000 quarter, up 50% compared to $11.0 million
in the prior year quarter.

The provision for income taxes on continuing operations decreased to
$5.8 million in the current year's quarter from $9.4 million in the prior
year's quarter. The decrease was due primarily to higher pre-tax income in the
prior year's quarter due to the $13.2 million gain on the litigation settlement
discussed above. The effective rate was 38.0% in both quarters.


                                       9
<PAGE>   11
Income from continuing operations was $9.4 million, or $0.29 per diluted share,
in the current year's quarter, compared to income from continuing operations of
$15.4 million, or $0.49 per diluted share, in the prior year's quarter. The
decrease was a result of the $13.2 million gain due to the reversal of the
excess accrual due to the settlement of litigation in the prior year's quarter,
partially offset by higher revenues and margins in the current year's quarter.

Net income, which includes continuing operations and discontinued operations,
was $11.0 million, or $0.34 per diluted share, for the current year's quarter
compared to net income of $15.6 million, or $0.50 per diluted share, for the
prior year's quarter. The decrease was a result of the $13.2 million gain due to
the reversal of the excess accrual due to the settlement of litigation in the
prior year's quarter, partially offset by higher revenues and margins in the
current year's quarter.


SIX MONTHS ENDED DECEMBER 31, 2000 COMPARED WITH
SIX MONTHS ENDED DECEMBER 31, 1999

Consolidated revenues increased 27.4% to $127.3 million in the six months ended
December 31, 2000, from $99.9 million in the six months ended December 31, 1999.
Total revenue increased $27.4 million: $18.8 million from increased machine
sales and $8.6 million from increased participation and lease revenue. We
shipped 9,563 video and reel type gaming devices in the current six month
period, resulting in product and parts sales of $85.9 million versus 8,384
gaming devices and $67.1 million of product and parts sales in the comparable
prior year period due to the continued market acceptance of new models
introduced over the last twelve months and the impact of the opening of the
California market. In addition, the average sales price increased from $7,553 in
the prior year's six month period to $8,311 in the current year's period
primarily due to a price increase implemented in August 2000 and a change in
sales mix to higher priced products.

The increase in participation and lease revenue resulted from an increase in the
installed base of participation gaming devices for which we had a total of 5,268
units installed at December 31, 2000, compared to 3,518 units installed at
December 31, 1999. Average net win per day for participation machines decreased
from $47.40 for the six month period ended December 31, 1999 to $44.08 for the
six month period ended December 31, 2000 due to an expansion of the installed
base to lower performing locations and the impact of first introducing JUMBLE in
the State of Nevada, which accounted for a majority of the JUMBLE revenues in
the December 2000 quarter, and which, in our experience, has the lowest average
daily rate of any domestic gaming jurisdiction.

Consolidated gross profit in the six month period ended December 31, 2000 rose
28.7% to $72.4 million from $56.3 million in the six month period ended
December 31, 1999. The gross margin percentage increased from 56.3% in the six
month period ended December 31, 1999 to 56.9% in the six month period ended
December 31, 2000. The increase in gross margin resulted from the increase in
gross margin on gaming machine sales from 41.0% in the December 1999 period to
42.9% in the December 2000 period, partially offset by lower gross profit
margins on participation and lease revenues from 87.9% to 85.9% due to a lower
average participation net win per day coupled with a government mandated
decrease in the net win percentage earned on our video lottery terminals placed
in Rhode Island and Delaware.

Research and development expenses increased $2.6 million, or 51.1%, in the
current six month period to $7.6 million from $5.0 million in the six month
period ended December 31, 1999 as we continued to invest in enhancing our
product pipeline and product platform. The increase was primarily due to higher
engineering expenditures, including costs to adapt our games for distribution to
international markets.

Selling and administrative expenses increased 26.1% from $19.9 million in the
prior year's period to $25.1 million in the current year's period as we
increased our cost structure to support our revenue growth.

Corporate relocation expenses of $3.1 million, or $0.06 per diluted share, in
the current year's six month period represent costs associated with the
relocation and centralization of our corporate headquarters, manufacturing,
distribution and warehousing facilities to Waukegan, Illinois. Of the relocation
expenses, $2.0 million, or $0.04 per diluted share, was for non-cash charges
related to the writedown of facilities and equipment.

These unusual charges are expected to be partially offset by greater
productivity and operating cost efficiencies realized upon the completion of the
relocation. We anticipate total charges associated with this relocation in the
current fiscal year to approximate $0.07 to $0.09 per diluted share.

Depreciation and amortization, which includes amortization of gaming machines
under participation and lease, increased during the current year's six month
period to $8.4 million from $7.0 million in the prior year's period due to the
increase in the installed base of participation machines under lease. The
average installed base was 4,417 units for the December 2000 period, compared to
3,174 units for the December 1999 period.

Operating income was $28.2 million in the current year's period, compared to
operating income of $37.5 million in the prior year's period. The decrease was a
result of the $13.2 million gain due to the reversal of the excess accrual due
to the settlement of litigation in the prior year's period, partially offset by
higher revenues and margins in the current year's period. In addition, the
financial results of the current year's period reflect the pre-tax charge of
$3.1 million from the costs associated with our relocation and centralization of
corporate headquarters, manufacturing, distribution and warehousing facilities
to Waukegan, Illinois. Operating income, prior to unusual items in both periods,
was $31.3 million in the six months ended December 31, 2000, up 28.6% compared
to $24.3 million in the prior year period.

The provision for income taxes on continuing operations decreased to $11.6
million in the current year's period from $14.8 million in the prior year's
period. The decrease was due primarily to lower pre-tax income. The effective
rate was 38.0% in both periods.

Income from continuing operations was $18.9 million, or $0.59 per diluted share,
in the current year's period, compared to income from continuing operations of
$24.2 million, or $0.78 per diluted share, in the prior year's period. The
decrease was a result of the $13.2 million gain discussed above, partially
offset by higher revenues and margins in the current year's period.

Net income, which includes continuing operations and discontinued operations,
was $20.5 million, or $0.64 per diluted share, for the current year's six month
period compared to net income of $10.8 million, or $0.35 per diluted share, for
the prior year's six month period. The increase was a result of higher revenues
and margins in the current year period, together with the $13.2 million gain
discussed above offset by the loss from discontinued operations in the prior
year's period.
