A.       GENERAL

         The accompanying unaudited consolidated financial statements of
         Gibraltar Packaging Group, Inc. ("Gibraltar" or the "Company") have
         been prepared in accordance with Rule 10-01 of Regulation S-X for
         interim financial statements required to be filed with the Securities
         and Exchange Commission and do not include all information and
         footnotes required by accounting principals generally accepted in the
         United States of America for complete financial statements. However, in
         the opinion of management, the accompanying unaudited consolidated
         financial statements contain all adjustments, consisting only of normal
         recurring adjustments, necessary to present fairly the financial
         position of the Company as of September 30, 2001, and the results of
         its operations and cash flows for the periods presented herein. Results
         of operations for the three months ended September 30, 2001 are not
         necessarily indicative of the results to be expected for the full
         fiscal year. The financial statements should be read in conjunction
         with the audited financial statements for the year ended June 30, 2001
         and the notes thereto contained in the Company's Annual Report on Form

C.       RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

         In June 2001, the Financial Accounting Standards Board ("FASB")
         approved the issuance of SFAS No. 141, "Business Combinations," and
         SFAS No. 142, "Goodwill and Other Intangible Assets." These standards
         establish accounting and reporting for business combinations, goodwill
         and other intangibles. SFAS No. 141 requires all business combinations
         entered into subsequent to June 30, 2001 to be accounted for using the
         purchase method of accounting. SFAS No. 142 provides that goodwill and
         other intangible assets with indefinite lives will not be amortized,
         but will be tested for impairment on an annual basis. SFAS No. 142 is
         effective for the Company beginning July 1, 2002. The Company has not
         quantified the impact resulting from the adoption of these standards
         including the impact, if any, of completion of the annual impairment
         test. However, the historical impact of not amortizing goodwill would
         have been to increase net income for the three months ended September
         30, 2001 and September 30, 2000 by $34,000 and $35,000, respectively.

         In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset
         Retirement Obligations". This standard addresses financial accounting
         and reporting for obligations related to the retirement of

                                       4

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)


         tangible long-lived assets and the related asset retirement costs. SFAS
         143 is effective for fiscal years beginning after June 15, 2002. The
         Company does not expect its adoption of this standard in fiscal 2003 to
         have a significant impact on the financial statements.

         In addition, in August 2001, the FASB issued SFAS No. 144, "Accounting
         for Impairment or Disposal of Long-Lived Assets". The standard
         addresses financial accounting and reporting for the impairment or
         disposal of long-lived assets and is effective for fiscal years
         beginning after December 15, 2001. The Company does not expect its
         adoption of this standard in fiscal 2003 to have a significant impact
         on the financial statements.

D.       RECLASSIFICATION

         Certain amounts in the fiscal 2001 financial statements have been
         reclassified to conform with the fiscal 2002 presentation.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

         Results of Operations

         Three Months Ended September 30, 2001 Compared to
         Three Months Ended September 30, 2000
         -------------------------------------

         In the first quarter of fiscal 2002, the Company had net sales of $15.4
         million compared with $16.4 million in the corresponding period of
         fiscal 2001, a decrease of $1.0 million or 6.3%. Sales continue to be
         negatively impacted by the overall slow-down in the economy.

         Gross profit for the first quarter of fiscal 2002 decreased to 19.5% of
         net sales from 21.6% in the corresponding period of fiscal 2001. This
         decrease was due primarily to spreading fixed manufacturing costs over
         a smaller revenue base, partially offset by continuing cost control
         efforts. Cost of goods sold decreased $0.5 million or 4.0% to $12.4
         million in the first quarter of fiscal 2002 compared to $12.9 million
         in the first quarter of fiscal 2001, primarily as a result of the
         reduction in net sales.

         Income from operations for the first quarter of fiscal 2002 was $1.1
         million compared with $1.5 million in the corresponding period of
         fiscal 2001, a decrease of $0.4 million or 28.1%. This decrease was
         primarily a result of the reduction in net sales, partially offset by
         continuing cost control efforts. Selling, general and administrative
         expenses decreased $0.1 million or 5.9% to $1.9 million in the first
         quarter of fiscal 2002, compared to $2.0 million in the corresponding
         period of fiscal 2001. This decrease was primarily the result of
         reduced personnel costs and continuing cost control efforts.

         Total interest expense decreased $0.3 million or 37.8% to $0.4 million
         in the first quarter of fiscal 2002 from $0.7 million in the
         corresponding period of fiscal 2001. The decrease is primarily the
         result of $3.9 million in lower average borrowings and lower average
         interest rates.

         The income tax provision as a percentage of pre-tax income for the
         first quarter of fiscal 2002 was 42.2%, compared with an income tax
         provision of 27.8% for the corresponding period in fiscal 2001. The
         effective tax rate typically differs from the statutory rate primarily
         as a result of non-deductible amortization of goodwill. However, as a
         result of earnings improvements, the Company reduced its deferred
         income tax asset valuation allowance by $0.1 million in the first
         quarter of fiscal 2001 to reflect a change in estimate related to the
         realizability of its deferred income tax assets.

         Net income for the first quarter of fiscal 2002 was $0.4 million or
         $0.07 per share, compared to $0.6 million or $0.11 per share in the
         first quarter of fiscal 2001. Net income for the first quarter of
         fiscal 2001 includes the effect of reducing the deferred income tax
         asset valuation allowance by $0.1 million, as a result of earnings
         improvements. Excluding the impact of the change in the deferred income
         tax asset valuation allowance, net income for the first quarter of
         fiscal 2001 would have been $0.5 million or $0.09 per share. The
         following table illustrates the effect of the income tax asset
         valuation allowance on the first quarter of fiscal 2001 (in thousands,
         except per share data):

         Financial Condition

         The Company's credit facility with First Source Financial LLP ("First
         Source"), as amended, provides for a five-year $25 million term loan
         and a five-year $12 million working capital revolving line of credit
         ("Revolver"). The loan requires monthly principal payments of $229,167
         through April 2003, with the balance of $9,692,435 due on July 31,
         2003. The credit facility is secured by a first priority perfected
         security interest in and lien on all assets (real and personal,
         tangible and intangible) of the Company excluding its Burlington, North
         Carolina property.

         The Revolver provides for a revolving line of credit under a borrowing
         base commitment subject to certain loan availability requirements. Loan
         availability under the Revolver may not exceed the lesser of (1) $12
         million or (2) the sum of (a) up to 85% of the Company's eligible
         accounts receivable plus (b) up to 60% of the Company's eligible
         inventory. At no time may the sum of aggregated loan advances
         outstanding under the Revolver plus the aggregate amount of extended
         letter of credit guarantees exceed loan availability. The Company had
         available to it unused borrowing capacity of $3.0 million as of
         September 30, 2001.

         The Revolver currently bears interest at First Source's prime rate plus
         1.25% or the London Interbank Offered Rate ("LIBOR") plus 3.25%. The
         term loan currently bears interest at First Source's prime rate plus
         1.75% or LIBOR plus 3.75%. The Company also pays a commitment fee of
         0.5% on the unused portion of the Revolver. The interest rates at
         September 30, 2001 were a combination of prime and LIBOR. First
         Source's prime and LIBOR rates were 6.00% and 3.58%, respectively, at
         September 30, 2001.

         As of September 30, 2001, all outstanding letters of credit were
         guaranteed by First Source. The Company pays a letter of credit fee of
         2.75% to guarantee availability under the Revolver. Outstanding letters
         of credit at September 30, 2001 amounted to $160,000 and relate to
         workman's compensation insurance policies.

         The First Source credit facility contains certain restrictive covenants
         including financial covenants related to net worth, minimum interest
         coverage ratio, capital expenditures, debt ratio and fixed charge
         coverage. As of September 30, 2001, the Company was in compliance with
         all financial covenants. In addition, the Company's credit facility
         restricts the ability of the Company to pay dividends.

         At September 30, 2001, the Company had working capital of $1.5 million,
         as compared to $2.4 million at June 30, 2001. Historically, the
         Company's liquidity requirements have been met by a combination of
         funds provided by operations and its revolving credit agreements. Funds
         provided by operations during the three months ended September 30, 2001
         were $1.9 million compared with funds provided of $1.4 million in the
         corresponding period in fiscal 2001.

         During the three months ended September 30, 2001, capital expenditures
         totaled $0.3 million compared with $0.2 million in the corresponding
         period in fiscal 2001, and consisted primarily of additions to
         machinery and equipment. The Company makes capital improvements to
         improve efficiency and product quality, and periodically upgrades its
         equipment by purchasing or leasing new or previously used equipment.

         The Company's current strategy is to continue to focus its efforts on
         its core business of folding cartons, as well as the supporting product
         lines of flexible, litho-laminated, and corrugated products. The
         Company intends to expand these product lines by utilizing the maximum
         capacity at each facility, while continually identifying, researching,
         and when applicable, implementing new technologies and equipment that
         will enable the Company to continue to improve performance,
         productivity, and profitability.

         Under the current strategy, management believes that future funds
         generated by operations and borrowings available under its credit
         facility with First Source will be sufficient to meet working capital
         and capital expenditure requirements in the near term.

         Recently Issued Accounting Pronouncements

         In June 2001, the Financial Accounting Standards Board ("FASB")
         approved the issuance of SFAS No. 141, "Business Combinations," and
         SFAS No. 142, "Goodwill and Other Intangible Assets." These standards
         establish accounting and reporting for business combinations, goodwill
         and other intangibles. SFAS No. 141 requires all business combinations
         entered into subsequent to June 30, 2001 to be accounted for using the
         purchase method of accounting. SFAS No. 142 provides that goodwill and
         other intangible assets with indefinite lives will not be amortized,
         but will be tested for impairment on an annual basis. SFAS No. 142 is
         effective for the Company beginning July 1, 2002. The Company has not
         quantified the impact resulting from the adoption of these standards
         including the impact, if any, of completion of the annual impairment
         test. However, the historical impact of not amortizing goodwill would
         have been to increase net income for the three months ended September
         30, 2001 and September 30, 2000 by $34,000 and $35,000, respectively.

         In July 2001, the FASB issued SFAS No. 143, "Accounting for Asset
         Retirement Obligations". This standard addresses financial accounting
         and reporting for obligations related to the retirement of

                                       8

         tangible long-lived assets and the related asset retirement costs. SFAS
         143 is effective for fiscal years beginning after June 15, 2002. The
         Company does not expect its adoption of this standard in fiscal 2003 to
         have a significant impact on the financial statements.

         In addition, in August 2001, the FASB issued SFAS No. 144, "Accounting
         for Impairment or Disposal of Long-Lived Assets". The standard
         addresses financial accounting and reporting for the impairment or
         disposal of long-lived assets and is effective for fiscal years
         beginning after December 15, 2001. The Company does not expect its
         adoption of this standard in fiscal 2003 to have a significant impact
         on the financial statements.

         Forward-Looking Statements

         Statements that are not historical facts, including statements about
         our confidence in the Company's prospects and strategies and our
         expectations about the Company's sales expansion, are forward-looking
         statements that involve risks and uncertainties. These risks and
         uncertainties include, but are not limited to: (1) softened demand for
         the Company's products due to overall economic conditions; (2) the
         Company's ability to execute its business plan; (3) market acceptance
         risks, including whether or not the Company will be able to
         successfully gain market share against competitors, many of which have
         greater financial and other resources than the Company, and the
         continuing trend of customers to increase their buying power by
         consolidating the number of vendors they maintain; (4) manufacturing
         capacity constraints, including whether or not, as the Company

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

         The Company's primary market risk is fluctuation in interest rates. All
         of the Company's debt at September 30, 2001 was at variable interest
         rates. A hypothetical 10% change in interest rates would have had an
         immaterial impact on interest expense for the three months ended
         September 30, 2001.

PART II. OTHER INFORMATION

Item 1.  Legal Proceedings

         From time to time, the Company is a party to certain lawsuits and
         administrative proceedings that arise in the conduct of its business.
         While the outcome of these lawsuits and proceedings cannot be predicted
         with certainty, management believes that, if adversely determined, the
         lawsuits and proceedings, either singularly or in the aggregate, would
         not have a material adverse effect on the financial condition, results
         of operations or net cash flows of the Company.

         On April 28, 1999, the Company filed a lawsuit captioned Gibraltar
         Packaging Group, Inc. v. Anthem Health Plans, d.b.a. Anthem Blue Cross
         and Blue Shield of Connecticut ("Anthem"), in the United States
         District Court for the District of Connecticut. The Company is seeking
         damages for Anthem's alleged breach of a contract for health insurance
         for employees of the Company. In October 2000, Anthem filed a
         counterclaim for unpaid premiums. The amount of the counterclaim is
         unknown. Discovery has revealed that a third party may be liable to
         indemnify the Company for all or part of the counterclaim, and the
         Company has brought a third party claim against this party in the
         litigation. There can be no assurances that the outcome of the
         litigation would not have an adverse impact on the Company. The parties
         participated in a settlement mediation in December 1999. The parties
         determined to gather additional information through depositions, ___
         which are ongoing. The Company anticipates another settlement mediation
         will be scheduled before the end of 2001.

Item 4.   Submission of Matters to a Vote of Security Holders

     No matters were submitted to a vote of Gibraltar's stockholders in the
     quarter ended September 30, 2001.

Item 6.   Exhibits and Reports on Form 8-K.

     (a)  Exhibits:

            None

     (b)  Reports on Form 8-K:
