             TWEETER HOME ENTERTAINMENT GROUP, INC. AND SUBSIDIARIES
         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.   Basis of Presentation

     The unaudited condensed consolidated financial statements of Tweeter Home
Entertainment Group, Inc. and its subsidiaries ("Tweeter" or the "Company"),
included herein, should be read in conjunction with the consolidated financial
statements and notes thereto included in Tweeter's Annual Report on Form 10-K
for the fiscal year ended September 30, 1999.

2.   Accounting Policies

     The unaudited consolidated financial statements of Tweeter have been
prepared in accordance with U.S. generally accepted accounting principles. In
the opinion of management, all adjustments (consisting only of normal recurring
accruals) considered necessary for a fair presentation of the interim
consolidated financial statements have been included. Operating results for the
six-month period ended March 31, 2000 are not necessarily indicative of the
results that may be expected for the fiscal year ending September 30, 2000.
Tweeter typically records its highest revenue and earnings in the first fiscal
quarter.

3.   Earnings per Share

     Tweeter computed earnings per share in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 128, "Earnings Per Share." Basic
earnings per share is calculated based on the weighted average number of common
shares outstanding, adjusted, in 1999, for the nominal issuance of certain
warrants. Diluted earnings per share is based on the weighted average number of
common shares outstanding, adjusted for the nominal issuance of certain
warrants, and dilutive potential common shares (common stock options and
warrants).

     The following is a reconciliation of the numerators and denominators of the
basic and diluted earnings per share:

5.   Investment in Joint Venture

     On October 4, 1999, Tweeter formed a joint venture with Outpost.com,
organized as Tweeter.Outpost.com, LLC, to jointly market and sell consumer
electronics over the Internet. The joint venture is accounted for by the Company
under the equity method. The investment is presented on the balance sheet as
"Investment in joint venture." As of March 31, 2000, total assets and total
liabilities of the joint venture amounted to $6,882,459 and $1,485,790,
respectively. For the three and six months ended March 31, 2000, the joint
venture had total revenue of $1,541,525 and $3,080,377, respectively. Income
before income taxes for the joint venture for the three and six months ended
March 31, 2000 was $181,970 and $396,668, respectively.

6.   Sound Installations

     On November 1, 1999, the Company purchased certain assets and assumed
certain liabilities of Sound Installations, Inc., a custom home installation
company. Total purchase price and related costs amounted to approximately
$210,000, including the issuance of 5,124 shares of common stock with a market
value at issuance of $110,000. The purchase price was allocated primarily to
goodwill and property and equipment. This transaction has been accounted for as
a purchase. The results of operations for the acquired entity in this fiscal
quarter were not significant. Accordingly, pro forma information has not been
presented.

7.  Follow-on Offering

    On February 7, 2000, Tweeter completed a follow-on public offering of
2,550,000 shares of common stock. The primary purpose of the offering was to
raise cash for Tweeter's working capital and for potential acquisitions. The
Company sold 2,000,000 shares in the offering and selling stockholders sold
550,000 shares. Net proceeds to the Company from the offering were approximately
$60,100,000.

8.   Subsequent Events

     On April 1, 2000, Tweeter completed the acquisition of certain assets and
liabilities of United Audio Centers, Inc. This transaction will be accounted for
as a purchase and, accordingly, the results of operations of the Company's
business relating to United Audio Centers will be included in the consolidated
statements of operations from the acquisition date. The total purchase price was
approximately $6,500,000, all of which was paid through the issuance of 200,000
shares of the Company's common stock.

9.   New Accounting Pronouncements

     During 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for
Derivative Instruments and Hedging Activities". SFAS No. 133 was not required to
be implemented until fiscal year 2000. In June 1999, the FASB issued SFAS No.
137, "Accounting for Derivative Instruments and Hedging Activities-Deferral of
the Effective Date of FASB Statement No. 133 - an amendment of FASB Statement
No. 133." SFAS No. 137 delayed the original implementation date of SFAS No. 133
by one year. This will require that the Company implement this statement in
fiscal year 2001. Management is currently evaluating the effects that the
adoption of SFAS No. 133 will have on the consolidated financial statements.

     On December 3, 1999, the Securities and Exchange Commission published Staff
Accounting Bulletin ("SAB") No. 101, "Revenue Recognition in Financial
Statements." This SAB summarizes certain of the staff's views in applying
generally accepted accounting principles to revenue recognition in financial
statements. This SAB requires, among other things, that revenues derived from
products or services in which companies typically act as an agent be reported on
a net basis. This SAB is required to be implemented by the Company in fiscal
year 2001. Had SAB No. 101 been implemented for all periods presented, total
revenue and cost of sales would have decreased by approximately $1.5 million for
the three months ended March 31, 2000, $0.9 million for the three months ended
March 31, 1999, $2.8 million for the six months ended March 31, 2000 and $1.7
million for the six months ended March 31, 1999. The adoption of SAB No. 101 is
not expected to have any other impact on results of operations.

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

INTRODUCTION

     Tweeter is a specialty retailer of mid to high-end audio and video consumer
electronics products. Tweeter currently operates 83 stores under the Tweeter,
etc., Bryn Mawr Stereo & Video, HiFi Buys, Home Entertainment, Dow Stereo/Video
and United Audio Centers names.

RESULTS OF OPERATIONS

THREE MONTHS ENDED MARCH 31, 2000 AS COMPARED TO THREE MONTHS ENDED MARCH 31,
1999

     Total Revenue. Total revenue includes delivered sales, completed service
center work orders, insurance replacement and corporate sales. Total revenue
increased $25.3 million, or 40.5%, to $87.5 million for the three months ended
March 31, 2000 from $62.2 million for the three months ended March 31, 1999. The
increase was mainly comprised of $6.4 million from new stores, comparable store
sales increase of $7.8 million, $2.6 million from the acquisition of Home
Entertainment, and $8.4 million from the acquisition of Dow Stereo/Video.
Comparable store sales, excluding Home Entertainment and Dow Stereo/Video,
increased by 12.2%. The Home Entertainment stores had a total comparable store
sales increase of 50.7%, and the DOW Stereo/Video stores had a comparable store
sales decrease of 5.9%. New technology products contributed to the sales
increase for the second quarter of fiscal 2000. DVD players represented
approximately 6.3% of total revenue for the three months ended March 31, 2000,
as compared to 4.1% for the same period in the prior year. Camcorder business
was up 20.3% and digital camcorders accounted for 65.7% of the camcorder sales.
Digital televisions accounted for 62.8% of all projection television sets sold
in the fiscal quarter ended March 31, 2000.

     Gross Profit. Cost of sales includes merchandise, net delivery costs,
distribution costs, purchase discounts, and vendor volume rebates. Cost of sales
increased $15.4 million, or 38.5%, to $55.3 million for the three months ended
March 31, 2000 from $39.9 million for the three months ended March 31, 1999.
Gross profit increased $9.9 million, or 44.3%, to $32.2 million for the three
months ended March 31, 2000 from $22.3 million for the three months ended March
31, 1999. The gross margin percentage increased 90 basis points, to 36.8% for
the three months ended March 31, 2000, from 35.9% for the three months ended
March 31, 1999. The increase in margin was primarily due to increased sales of
new digital technology products, such as DVD players, digital televisions and
digital camcorders. These digital products realize higher gross margin and
higher average ticket than their analog counterparts. This increase was offset
by growth in the video category relative to other categories that Tweeter sells.


                                       8
<PAGE>   9

Video products generally realize lower gross margin than audio products.
Tweeter expects sales of digital televisions to accelerate over the next few
years, which will tend to increase video sales as a percentage of the Company's
overall mix. It is a particular challenge for Tweeter to enact strategies such
as its "Sell Audio with Video" strategy in order to offset the margin erosion
that could occur due to an increase in sales of video products relative to the
other categories of products that Tweeter sells.

     Selling Expenses. Selling expenses include the compensation of store
personnel, occupancy costs, store level depreciation, advertising expenses,
pre-opening expenses and credit card fees and excludes corporate, general and
administrative expenses. Selling expenses increased $6.4 million, or 38.9%, to
$22.8 million for the three months ended March 31, 2000 from $16.4 million for
the three months ended March 31, 1999. As a percentage of revenue, selling
expenses decreased to 26.1% for the three months ended March 31, 2000 from 26.4%
for the three months ended March 31, 1999. This decrease was primarily due to
lower net advertising costs resulting from additional coop advertising money
received from our vendors.

     Corporate, General and Administrative Expenses. Corporate, general and
administrative expenses include the costs of executive officers, finance,
merchandising, marketing, information systems, human resources, training, and
related support functions. Corporate, general and administrative expenses
increased 42.4% to $4.6 million for the three months ended March 31, 2000 from
$3.2 million for the three months ended March 31, 1999. As a percentage of total
revenue, corporate general and administrative expenses remained constant at
5.2%.

     Amortization of Goodwill. Amortization of goodwill increased to $338,000
for the three months ended March 31, 2000 from $255,000 for the three months
ended March 31, 1999. The increase was due to the completion of the Home
Entertainment acquisition on February 1, 1999 and the Dow Stereo/Video
acquisition on July 1, 1999.

    Interest Expense. Interest expense increased to $88,000 for the three months
ended March 31, 2000 from $37,000 for the three months ended March 31, 1999. The
increase was due to the incurrence of higher debt levels for the fiscal 2000
period in order to facilitate the building of new stores and the relocation of
existing stores.

     Income Taxes. The effective tax rate for the fiscal quarters ended March
31, 2000 and March 31, 1999 was 40.0%. Tweeter expects that the income tax rate
for the fiscal year ending September 30, 2000 will remain substantially
unchanged.

     Seasonality. Tweeter's operations, in common with other retailers, are
subject to seasonal influences. Historically, Tweeter has realized more of its
revenue and net earnings in the first fiscal quarter, which includes the holiday
season, than in any other fiscal quarter. The net earnings of any interim
quarter are seasonally disproportionate to net sales since certain selling
expenses and administrative expenses are relatively fixed during the year.
Therefore, interim results should not be relied upon as necessarily indicative
of results for the entire fiscal year.

SIX MONTHS ENDED MARCH 31, 2000 AS COMPARED TO SIX MONTHS ENDED MARCH 31, 1999

    Total Revenue. Total revenue increased $63.3 million, or 42.5%, to $212.3
million for the six months ended March 31, 2000 from $149.0 million for the six
months ended March 31, 1999. The increase was mainly comprised of $14.1 million
from new stores, $17.1 million from comparable store sales growth, $12.0 million
from the acquisition of Home Entertainment of Texas and $19.3 million from the
acquisition of Dow Stereo/Video. Comparable store sales increased by 12.0%
excluding the Home Entertainment and Dow Stereo/Video chains. New technology
products fueled sales performance for the first six months of fiscal 2000. DVD
players represented approximately 7.7% of total revenue for the six months ended
March 31, 2000 as compared to approximately 5.1% of total revenue for the six
months ended March 31, 1999.

    Gross Profit. Cost of sales increased $37.3 million, or 38.4% to $134.4
million for the six months ended March 31, 2000 from $97.1 million for the six
months ended March 31, 1999. Gross profit increased $26.0 million, or 50.1% to
$77.9 million for the six months ended March 31, 2000 from $51.9 million for the
six months ended March 31, 1999. The gross margin increased 190 basis points to
36.7% from 34.8% last year. The increase in margin is primarily due to increased
sales of new digital technology products, such as DVD players, digital
televisions and digital camcorders.


                                       9
<PAGE>   10
These digital products realize higher gross margin and higher average ticket
than their analog counterparts. This increase was offset by growth in the video
category relative to other categories that Tweeter sells. Video products
generally realize lower gross margin than audio products. The Company expects
sales of digital televisions to accelerate over the next few years, which will
tend to increase video sales as a percentage of the Company's overall mix.

    Selling Expenses. Selling expenses increased $15.9 million, or 46.8%, to
$49.8 million for the six months ended March 31, 2000 from $33.9 million for the
six months ended March 31, 1999. As a percentage of revenue, selling expenses
increased to 23.5% for the six months ended March 31, 2000 from 22.8% in the
prior year period. This increase was primarily the result of increased payroll
costs associated with higher gross margin sales, increased bank fees due to
extended credit card financing promotions offset by lower net advertising costs.

    Corporate, General and Administrative Expenses. Corporate, general and
administrative expenses for the six months ended March 31, 2000 increased 27.1%
to $9.2 million from $7.3 million for the six months ended March 31, 1999. As a
percentage of total revenue, corporate general and administrative expenses
decreased to 4.3% for the six months ended March 31, 2000 from 4.9% for the
prior year period. This decrease was the result of leveraging the additional
sales volume of new stores and the acquisitions of Home Entertainment and Dow
Stereo/Video.

    Amortization of Goodwill. Amortization of goodwill increased to $670,000 for
the six months ended March 31, 2000 from $471,000 for the six months ended March
31, 1999. The increase was due to the Home Entertainment acquisition on February
1, 1999, the Dow Stereo acquisition on July 1, 1999 as well as the acquisition
of two custom installation companies.

    Interest Expense. Interest expense increased to $346,000 for the six months
ended March 31, 2000 from $237,000 for the six months ended March 31, 1999. The
increase was due to the incurrence of higher debt levels for the fiscal 2000
period in order to facilitate the building of new stores and the relocation of
existing stores.

    Income Taxes. The effective tax rate for the six months ended March 31, 2000
and March 31, 1999 was 40.0%. Tweeter expects that the income tax rate for the
year ending September 30, 2000 will approximate 40.0%.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash used by operating activities was $586,000 for the six months ended
March 31, 2000 compared to $7.6 million in cash provided by operating activities
for the six months ended March 31, 1999. Cash used by operations in 2000 was
primarily the result of increases in inventory of $10.3 million and accounts
receivable of $4.4 million. Inventory was maintained at a higher level due to
the lack of availability of the newer digital products. This was offset by $10.8
million in net income, depreciation and amortization of $3.3 million and an
increase in customer deposits of $1.2 million, as well as minor changes in other
operating accounts.

     At March 31, 2000, working capital was $88.7 million, compared to $31.5
million at September 30, 1999. The increase was primarily due to the follow-on
public offering completed on February 7, 2000. The ratio of current assets to
current liabilities was 2.96 to 1 at March 31, 2000 and 1.72 to 1 at September
30, 1999. Capital expenditures for the six months ended March 31, 2000 were $7.8
million, primarily used for the building of new stores and the relocation of
existing stores.

     Net cash provided by financing activities during the six months ended March
31, 2000 was $52.7 million, comprised mainly of proceeds generated from the sale
of 2,000,000 shares of common stock on February 7, 2000. This was offset by
payments made for long-term debt of $5.7 million and an investment in our
Tweeter.Outpost.com joint venture of $2.7 million.

     The Company had available at March 31, 2000 a $50,000,000 revolving credit
facility, and there were no balances outstanding at March 31, 2000.


                                       10
<PAGE>   11

     On January 11, 2000, Tweeter filed a registration statement with the
Securities and Exchange Commission for a public offering of both primary shares
and shares that were sold by certain selling stockholders. The offering
consisted of 2,550,000 shares of common stock, 550,000 of which were offered by
selling stockholders and 2,000,000 of which were offered by the Company. The
Company raised proceeds of $60.1 million net of related expenses.

    On April 1, 2000, Tweeter completed the acquisition of certain assets and
liabilities of United Audio Centers, Inc. This transaction will be accounted for
as a purchase and, accordingly, the results of operations of the Company's
business relating to United Audio Centers will be included in the consolidated
statements of operations from the acquisition date. The total purchase price was
approximately $6,500,000, all of which was paid through the issuance of 200,000
shares of the Company's common stock.

    Tweeter believes that the net proceeds from the February 2000 offering,
together with cash generated by operations and available borrowings under its
credit facility will be sufficient to finance its working capital and capital
expenditure requirements for at least the next twelve months. If management
pursues additional acquisitions within this period, however, such acquisitions
could strain Tweeter's capital resources. Furthermore, due to the seasonality of
its business, Tweeter's working capital needs are significantly higher the
fiscal third and fourth quarters and there is the possibility that this could
cause unforeseen capital constraints in the future.

FORWARD-LOOKING STATEMENTS

     Certain statements contained in this Quarterly Report on Form 10-Q,
including, without limitation, statements containing the words "expects,"
"anticipates," "believes" and words of similar import, constitute "forward
looking statements" within the meaning of the Private Securities Litigation
Reform Act of 1995. These forward looking statements are subject to various
risks and uncertainties, including those relating to Company growth and
acquisitions, dependence on key personnel, the need for additional financing,
competition and seasonal fluctuations, and those referred to in Tweeter's
Registration Statement filed on Form S-3 (SEC file number 333-94433) on January
11, 2000 and in the Company's Annual Report on Form 10-K filed on December 10,
1999, that could cause actual future results and events to differ materially
from those currently anticipated. Readers are cautioned not to place undue
reliance on these forward-looking statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Tweeter's credit facility provides for borrowings which bear interest at
variable rates based on either (i) the higher of Fleet National Bank's Base Rate
or the Federal Funds rate plus 0.50% or (ii) the London Interbank Offering Rate
(LIBOR) plus an applicable margin varying from 100 to 175 basis points. Tweeter
had no borrowings outstanding pursuant to the credit facility as of March 31,
2000. Tweeter believes that the effect, if any, of reasonably possible near-term
changes in interest rates on Tweeter's financial position, results of
operations, and cash flows should not be material.

     At March 31, 2000, the Company had approximately $2.4 million in marketable
equity securities classified as "available-for-sale." Equity market fluctuations
can impact fair values (although not earnings, unless such equity positions are
actually liquidated). A 10% fluctuation in the value of such securities would
either reduce or increase total assets by approximately $240,000.

     Currently, Tweeter does not enter into financial instrument transactions
for speculative purposes or to manage interest rate exposure.
