                        DIAMOND TRIUMPH AUTO GLASS, INC.
                    NOTES TO FINANCIAL STATEMENTS (Unaudited)
                 (Dollars in thousands except per share amounts)



NOTE 1.   SIGNIFICANT ACCOUNTING POLICIES

          These interim financial statements are unaudited but, in the opinion
          of management, reflect all adjustments (consisting only of normal
          recurring adjustments) necessary to present fairly the data for the
          interim periods presented. The interim financial statements should be
          read in conjunction with the audited financial statements and notes
          thereto contained in Diamond's Annual Report on Form 10-K for the
          fiscal year ended December 31, 2001. Diamond's results for interim
          periods are not normally indicative of results to be expected for the
          fiscal year. Weather has historically affected Diamond's sales, net
          income and EBITDA, with severe weather generating increased sales, net
          income and EBITDA and mild weather resulting in lower sales, net
          income and EBITDA. In addition, Diamond's business is somewhat
          seasonal, with the first and fourth calendar quarters traditionally
          its slowest periods of activity.

          Preferred Stock - At June 30, 2002 and December 31, 2001, the
          liquidation value of the Preferred Stock recorded on Diamond's Balance
          Sheet was $57,850 and $54,530, respectively, which includes dividends
          of $22,850 and $19,530, respectively, added to the liquidation value.

          Long-Term Debt:

          Credit Facility - On March 27, 2000, Diamond entered into a revolving
          credit facility (the "Credit Facility"). The Credit Facility has an
          initial term of four years and provides for revolving advances of up
          to the lesser of: (1) $25,000; (2) the sum of 85% of Diamond's
          Eligible Accounts Receivable (as defined in the Credit Facility) plus
          85% of Diamond's Eligible Inventory (as defined in the Credit
          Facility), less certain reserves; or (3) an amount equal to 1.5 times
          Diamond's EBITDA (as defined in the Credit Facility) for the prior
          twelve months. A portion of the Credit Facility, not to exceed $5,000,
          is available for the issuance of letters of credit, which generally
          have an initial term of one year or less. Borrowings under the Credit
          Facility bear interest, at Diamond's discretion, at either the Chase
          Manhattan Bank Rate (as defined in the Credit Facility) or LIBOR, plus
          a margin of 0.25% for the Chase Manhattan Rate and 2.0% for the LIBOR
          Rate. In addition, a commitment fee of 0.25% is charged against any
          unused balance of the Credit Facility. Interest rates are subject to
          increases or reductions based upon Diamond meeting certain EBITDA
          levels. The proceeds of the Credit Facility are available for working
          capital requirements and for general corporate purposes. The Credit
          Facility is secured by first priority security interests in all of
          Diamond's tangible and intangible assets. In addition, the Credit
          Facility contains certain restrictive covenants including, among other
          things, the maintenance of a minimum EBITDA level for the prior twelve
          months, as well as restrictions on additional indebtedness, dividends
          and certain other significant transactions. Diamond was in compliance
          with these covenants at June 30, 2002. At June 30, 2002, Diamond did
          not have any borrowings outstanding under the Credit Facility.


NOTE 2.   RECENT ACCOUNTING PRONOUNCEMENTS

          In April 2002 Diamond implemented Statement of Financial Accounting
          Standards ("SFAS") No. 145, "Rescission of FASB Statements No. 4, 44
          and 64, Amendment of FASB Statement No. 13 and Technical Corrections".
          This statement rescinds Statements No. 4 and 64 and establishes APB
          Opinion No. 30 as the criteria to be used in reporting gains and
          losses from extinguishment of debt. Statement No. 145 rescinds
          Statement No. 44, which dealt with accounting requirements for the
          effects of transition to the provisions of the Motor Carrier Act of
          1980. Statement No. 145 also requires that certain lease modifications
          that have economic effects similar to sale-leaseback transactions be
          accounted for in the same manner as sale-leaseback transactions.
          Diamond does not expect adoption of SFAS No. 145 to have a material
          impact on its financial statements.

                        DIAMOND TRIUMPH AUTO GLASS, INC.
                    NOTES TO FINANCIAL STATEMENTS (Unaudited)
                 (Dollars in thousands except per share amounts)


          In 2001, Statement of Financial Accounting Standards ("SFAS") No. 144,
          "Accounting for the Impairment or Disposition of Long-Lived Assets"
          was issued. This standard establishes one accounting model to be used
          for measuring impairment of long-lived assets. Diamond does not expect
          adoption of SFAS No. 144 to have a material impact on its financial
          statements.


NOTE 3.   EXECUTIVE COMPENSATION

          On June 1, 2002, Diamond entered into an employment agreement with
          Norman Harris (the "Executive") pursuant to which Mr. Harris agreed to
          serve as the Chief Executive Officer of Diamond at an annual salary of
          $400 (the "Base Salary"), subject to annual review based on Diamond's
          and the Executive's performance. The employment agreement provides for
          an initial term of four years beginning on June 1, 2002 and ending on
          June 1, 2006. In addition to the Base Salary, the Executive is
          eligible to receive a bonus based upon the achievement of certain
          criteria to be mutually agreed upon by the Executive and the Board of
          Directors of Diamond. The employment agreement also contains various
          severance, non-competition, non-solicitation provisions,
          non-disclosure and assignment of inventions provisions.

          On June 1, 2002 (the "Grant Date"), the Executive and Diamond entered
          into a Restricted Stock Agreement (the "Agreement") pursuant to which
          the Executive purchased from Diamond 26,366 shares (the "Restricted
          Shares") of Diamond's common stock, par value $0.01 per share, for
          nominal consideration. The Agreement generally restricts the sale or
          transferability of shares of Common Stock held by the Executive before
          the Restrictions (as defined in the Agreement) have lapsed. The
          Executive has all rights and privileges of a stockholder with respect
          to the Restricted Shares, including voting rights and the right to
          receive dividends paid with respect to the Restricted Shares.
          Generally, the Restricted Shares vest and the Restrictions lapse: (i)
          with respect to 20% of the Restricted Shares on the Grant Date and;
          (ii) with respect to 20% of the Restricted Shares on each subsequent
          anniversary of the Grant Date until the Restricted Shares are fully
          vested. Compensation expense, unearned restricted stock compensation,
          and proceeds from common stock issued have been recognized based on
          the vesting periods and an estimated fair market value of $20 per
          share.

NOTE 4.   LEGAL PROCEEDINGS

          On May 2, 2002, Diamond filed an amended Complaint with the United
          States District Court, Middle District of Pennsylvania against
          Safelite Glass Corporation (the "Defendant"). Diamond alleges, among
          other things, that the Defendant's conduct as (i) an operator of
          national telephone call centers which takes first notice of loss calls
          from insureds of several of the largest automobile insurers in the
          United States (the "Insurers"); (ii) a provider of various claims
          processing services to the Insurers as a third-party administrator
          and; (iii) an operator of a network of retail repair and replacement
          facilities who perform work for the Insurers as Safelite affiliates,
          violated certain federal and state laws and give rise to other legal
          and equitable claims against the Defendant. Diamond alleges that the
          Defendant engaged in various practices designed to divert customers
          away from Diamond to the Defendant, and that Diamond has suffered
          damages as a result of this conduct in an amount to be determined at
          trial.

NOTE 5.   INCOME TAXES

          As disclosed in the Company's 10-K for the year ended December 31,
          2001, on February 20, 2002 the Internal Revenue Service issued a
          notice of proposed adjustments, which included disallowance of
          Diamond's tax deductible goodwill from Diamond's March 31, 1998
          recapitalization Transaction (as defined in the Company's 10-K for
          the year ended December 31, 2001).

          The proposed adjustments by the Internal Revenue Service would result
          in $3.8 million of federal tax deficiencies owed by Diamond for the
          period December 31, 1998 through December 31, 2000, plus possible
          interest and penalties and any resultant increases in current state
          tax expense for this period. Additionally, the deferred tax asset
          established in 1998 would be eliminated, as well as net operating loss
          carryforwards from previous deductions of the tax goodwill. The
          carrying amount of these assets at December 31, 2001 is approximately
          $39.1 million. In addition, Diamond would be responsible to fund a
          current federal tax liability for 2001 and for the six months ended
          June 30, 2002 of approximately $2.8 million and $1.3 million,
          respectively, plus possible interest and penalties, and any resultant
          increases in current state tax expense for 2001 and 2002.

          Diamond continues to strongly believe that the Transaction was
          properly accounted for, and plans to appeal the Internal Revenue
          Service's proposed adjustment. If such appeal were ultimately
          unsuccessful, the Internal Revenue Service's proposed adjustment would
          have a material adverse affect on Diamond's liquidity, cash flows,
          balance sheet and results of operations.

(1)  EBITDA represents income before taxes, interest expense, depreciation and
     amortization expense. While EBITDA is not intended to represent cash flow
     from operations as defined by GAAP and should not be considered as an
     indicator of operating performance or an alternative to cash flow (as
     measured by GAAP), as a measure of liquidity, it is included herein to
     provide additional information with respect to Diamond's ability to meet
     its future debt service, capital expenditure and working capital
     requirements.


SIX MONTHS ENDED JUNE 30, 2002 COMPARED TO SIX MONTHS ENDED JUNE 30, 2001

     Net Sales. Net sales for the six months ended June 30, 2002 decreased by
$3.3 million, or 3.1%, to $102.6 million from $105.9 million for the six months
ended June 30, 2001. For the six months ended June 30, 2002, installation units
decreased 3.9% and revenue per installation unit increased an average of 0.8%.
The decrease in units sold is primarily due to the historically mild winter
weather conditions experienced throughout a large portion of the United States
and the recessionary economic climate, which resulted in weaker industry demand.
The increase in Diamond's average revenue per installation unit is attributable
to general price increases and to Diamond's sales mix.

     Gross Profit. Gross profit for the six months ended June 30, 2002 decreased
by $2.2 million, or 2.9%, to $73.9 million from $76.1 million for the six months
ended June 30, 2001. Gross profit increased as a percentage of sales to 72.0%
for the six months ended June 30, 2002 from 71.9% for the six months ended June
30, 2001. The decrease in gross profit for the six months ended June 30, 2002
was primarily due to a decrease in net sales compared to the six months ended
June 30, 2001 which was partially offset by the increased average revenue per
installation unit.


                                       10

     Operating Expenses. Operating expenses for the six months ended June 30,
2002 increased by $3.4 million, or 5.5%, to $65.1 million from $61.7 million
for the six months ended June 30, 2001. Operating expenses increased as a
percentage of sales to 63.5% for the six months ended June 30, 2002 from 58.3%
for the six months ended June 30, 2001. The increase in operating expense
during the six months ended June 30, 2002 compared to the six months ended June
30, 2001 was primarily due to an increase in service center costs related to
expansion, primarily for wages and wage related expenses, advertisement and
promotional expenses and occupancy costs. The increase in operating expenses
was also due to a general increase in wages and wage related expenses
experienced primarily at service centers combined with an increase in insurance
expense due to rising insurance premiums and an increase in advertisement and
promotional expenses.

     Depreciation and amortization expense for the six month period ended June
30, 2002 increased by $0.2 million, or 16.7%, to $1.4 million from $1.2 million
for the six months ended June 30, 2001. This increase was primarily due to the
amortization and depreciation expense related to certain sales, billing and
financial systems software and computer hardware implemented in the latter half
of 2001 and the first half of 2002. This increase was partially offset by a
decrease in expense due to the increased use of a master fleet leasing program
for the lease of mobile installation and distribution service vehicles.

     Income From Operations. Income from operations for the six months ended
June 30, 2002 decreased by $5.6 million, or 38.9%, to $8.8 million from $14.4
million for the six months ended June 30, 2001. This decrease was primarily due
to the decrease in net sales and increase in operating expenses as discussed
above.

     Interest Expense. Interest expense for the six months ended June 30, 2002
decreased $0.1 million to $5.1 million from $5.2 million for the six months
ended June 30, 2001. Cash interest expense was $4.7 million for the six months
ended June 30, 2002 and June 30, 2001. The decrease was primarily due to a
reduction in outstanding borrowings under the Company's Credit Facility during
the six months ended June 30, 2002 compared to the six months ended June 30,
2001.

     Net Income. Net income for the six months ended June 30, 2002 decreased by
$3.4 million to $2.2 million from $5.6 million for the six months ended June 30,
2001. Net income as a percentage of sales decreased to 2.1% for the six months
ended June 30, 2002 from 5.3% for the six months ended June 30, 2001. The
decrease in net income and net income margin during the six months ended June
30, 2002 compared to the six months ended June 30, 2001 was primarily due to the
impact of decreased net sales and increased operating expenses.

     EBITDA. EBITDA for the six months ended June 30, 2002 decreased by $5.4
million, or 34.4%, to $10.3 million from $15.7 million for the six months ended
June 30, 2001. EBITDA as a percentage of sales decreased to 10.0% for the six
months ended June 30, 2002 from 14.8% for the six months ended June 30, 2001.
The decrease in EBITDA and EBITDA margin for the six months ended June 30, 2002
was primarily due to the decrease in net sales and increase in operating
expenses as discussed above.


THREE MONTHS ENDED JUNE 30, 2002 COMPARED TO THREE MONTHS ENDED JUNE 30, 2001

     Net Sales. Net sales for the three months ended June 30, 2002 decreased by
$1.4 million, or 2.5%, to $54.4 million from $55.8 million for the three months
ended June 30, 2001. During the three months ended June 30, 2002, installation
units decreased by 2.9% and revenue per installation unit increased an average
of 0.5%. The decrease in units sold is primarily due to the historically mild
winter weather conditions experienced throughout a large portion of the United
States and the recessionary economic climate, which resulted in weaker industry
demand. The increase in Diamond's average revenue per installation unit is
attributable to general price increases and to Diamond's sales mix.

     Gross Profit. Gross profit for the three months ended June 30, 2002
decreased by $0.9 million, or 2.2%, to $39.4 million from $40.3 million for the
three months ended June 30, 2001. Gross profit increased as a percentage of
sales to 72.4% for the three months ended June 30, 2002 from 72.2% for the three

                                       11
<PAGE>

months ended June 30, 2001. The decrease in gross profit for the three months
ended June 30, 2002 was primarily due to a decrease in net sales compared to the
three months ended June 30, 2001, which was partially offset by the increased
average revenue per installation unit.

     Operating Expenses. Operating expenses for the three months ended June 30,
2002 increased by $1.5 million, or 4.7%, to $33.3 million from $31.8 million
for the three months ended June 30, 2001. Operating expenses increased as a
percentage of sales to 61.2% for the three months ended June 30, 2002 from
57.0% for the three months ended June 30, 2001. The increase in operating
expense during the three months ended June 30, 2002 compared to the three
months ended June 30, 2001 was primarily due to an increase in service center
costs related to expansion, primarily for wages and wage related expenses,
advertisement and promotional expenses and occupancy costs. The increase in
operating expenses was also due to a general increase in wages and wage related
expenses experienced primarily at service centers combined with an increase in
insurance expense due to rising insurance premiums and an increase in
advertisement and promotional expenses.

     Depreciation and amortization expense for the period ended June 30, 2002
increased by $0.1 million, or 16.7%, to $0.7 million from $0.6 million for the
three months ended June 30, 2001. This increase was primarily due to the
amortization and depreciation expense related to certain sales, billing and
financial systems software and computer hardware implemented in the latter half
of 2001 and the first half of 2002. This increase was partially offset by a
decrease in expense due to the increased use of a master fleet leasing program
for the lease of mobile installation and distribution service vehicles.

     Income From Operations. Income from operations for the three months ended
June 30, 2002 decreased by $2.4 million, or 28.2%, to $6.1 million from $8.5
million for the three months ended June 30, 2001. This decrease was primarily
due to the decrease in net sales and increase in operating expenses as discussed
above.

     Interest Expense. Interest expense remained at $2.6 million for the three
months ended June 30, 2002 and 2001. Cash interest expense also remained at $2.3
million for the three months ended June 30, 2002 and 2001.

     Net Income. Net income for the three months ended June 30, 2002 decreased
by $1.6 million to $2.0 million from $3.6 million for the three months ended
June 30, 2001. Net income as a percentage of sales decreased to 3.7% for the
three months ended June 30, 2002 from 6.5% for the three months ended June 30,
2001. The decrease in net income and net income margin during the three months
ended June 30, 2002 compared to the three months ended June 30, 2001 was
primarily due to the impact of decreased net sales and increased operating
expenses.

     EBITDA. EBITDA for the three months ended June 30, 2002 decreased by $2.4
million, or 26.1%, to $6.8 million from $9.2 million for the three months ended
June 30, 2001. EBITDA as a percentage of sales decreased to 12.5% for the three
months ended June 30, 2002 from 16.5% for the three months ended June 30, 2001.
The decrease in EBITDA for the three months ended June 30, 2002 was primarily
due to the decrease in net sales and increase in operating expenses as discussed
above.

 LIQUIDITY AND CAPITAL RESOURCES

     Diamond's need for liquidity will arise primarily from the interest payable
on its 9 1/4% Senior Notes (the "Notes"), its Credit Facility and the funding of
Diamond's capital expenditures and working capital requirements. There are no
mandatory principal payments on the Notes prior to their maturity on April 1,
2008 and, except to the extent that the amount outstanding under the Credit
Facility exceeds the borrowing base, no required payments of principal on the
Credit Facility prior to its expiration on March 27, 2004.

     Net Cash Provided by Operating Activities. Net cash provided by operating
activities for the six months ended June 30, 2002 decreased by $3.2 million to
$4.8 million from $8.0 million for the six months ended June 30, 2001. The
change was primarily attributable to a decrease in Diamond's net earnings and a
$4.6 million increase in accounts receivable which was partially offset by a
$1.3 million decrease in inventory and $1.6 million increase in accrued
expenses.

     Net Cash Used in Investing Activities. Net cash used in investing
activities for the six months ended June 30, 2002 increased $0.8 million to $2.2
million from $1.4 million used in investing activities for the six months ended
June 30, 2001. The primary reason for the variance was an increase in capital
expenditures.

     Net Cash Used in Financing Activities. Net cash used in financing
activities in the six months ended June 30, 2002 was $0.1 million compared to
$0.6 million used in financing activities in the six months ended June 30, 2001.
The primary reasons for this decrease in cash used by financing activities was
the lack of borrowing on the Credit Facility during the six months ended June
30, 2002.

     Capital Expenditures. Capital expenditures for the six months ended June
30, 2002 were $2.3 million, as compared to $1.5 million for the six months ended
June 30, 2001. Capital expenditures for the six months ended June 30, 2002 were
made primarily to fund the continued upgrade of Diamond's management information
systems.

     Liquidity. Management believes that Diamond will have adequate capital
resources and liquidity to satisfy its debt service obligations, working capital
needs and capital expenditure requirements, including those related to the
opening of new service centers and distribution centers for the foreseeable
future. Diamond's capital resources and liquidity are expected to be provided by
Diamond's net cash provided by operating activities and borrowings under the
Credit Facility. See "--Notes to Financial Statements -- Note 5 -- Income Tax"
for a discussion of the Internal Revenue Service's proposed adjustments with
respect to Diamond's tax treatment of its recapitalization Transaction (as
defined in the Company's 10-K for the year ended December 31, 2001) entered
into by Diamond and other parties in January 1998.

RELATED PARTY TRANSACTIONS

On June 1, 2002, Diamond entered into an employment agreement with Norman Harris
(the "Executive") pursuant to which Mr. Harris agreed to serve as the Chief
Executive Officer of Diamond at an annual salary of $400,000 (the "Base
Salary"), subject to annual review based on Diamond's and the Executive's
performance. The employment agreement provides for an initial term of four years
beginning on June 1, 2002 and ending on June 1, 2006. In addition to the Base
Salary, the Executive is eligible to receive a bonus based upon the achievement
of certain criteria to be mutually agreed upon by the Executive and the Board of
Directors of Diamond. The employment agreement also contains various severance,
non-competition, non-solicitation provisions, non-disclosure and assignment of
inventions provisions.

On June 1, 2002 (the "Grant Date"), the Executive and Diamond entered into a
Restricted Stock Agreement (the "Agreement") pursuant to which the Executive
purchased from Diamond 26,366 shares (the "Restricted Shares") of Diamond's
common stock, par value $0.01 per share, for nominal consideration. The
Agreement generally restricts the sale or transferability of shares of Common
Stock held by the Executive before the Restrictions (as defined in the
Agreement) have lapsed. The Executive has all rights and privileges of a
stockholder with respect to the Restricted Shares, including voting rights and
the right to receive dividends paid with respect to the Restricted Shares.
Generally, the Restricted Shares vest and the Restrictions lapse: (i) with
respect to 20% of the Restricted Shares on the Grant Date and; (ii) with
respect to 20% of the Restricted Shares on each subsequent anniversary of the
Grant Date until the Restricted Shares are fully vested. Compensation expense,
unearned restricted stock compensation, and proceeds from common stock issued
have been recognized based on the vesting periods and an estimated fair market
value of $20 per share.

ITEM 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

          Diamond has a revolving Credit Facility that provides for revolving
          advances of up to $25.0 million, and matures in March 2004. Borrowings
          under the Credit Facility bear interest, at Diamond's discretion, at
          either the Chase Manhattan Bank Rate (as defined in the Credit
          Facility) or LIBOR, plus a margin of 0.25% for the Chase Manhattan
          Rate and 2.0% for the LIBOR Rate. In addition, a commitment fee of
          0.25% is charged against any unused balance of the Credit Facility.
          Interest rates are subject to increases or reductions based upon
          Diamond meeting certain EBITDA levels. At June 30, 2002, Diamond did
          not have any borrowings outstanding under the Credit Facility.

ITEM 1. LEGAL PROCEEDINGS

     On May 2, 2002, Diamond filed an amended Complaint with the United States
District Court, Middle District of Pennsylvania against Safelite Glass
Corporation (the "Defendant"). Diamond alleges, among other things, that the
Defendant's conduct as (i) an operator of national telephone call centers which
takes first notice of loss calls from insureds of several of the largest
automobile insurers in the United States (the "Insurers"); (ii) a provider of
various claims processing services to the Insurers as a third-party
administrator and; (iii) an operator of a network of retail repair and
replacement facilities who perform work for the Insurers as Safelite affiliates,
violated certain federal and state laws and give rise to other legal and
equitable claims against the Defendant. Diamond alleges that the Defendant
engaged in various practices designed to divert customers away from Diamond to
the Defendant, and that Diamond has suffered damages as a result of this conduct
in an amount to be determined at trial.
