                         JACLYN, INC. AND SUBSIDIARIES


       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

     1.    The condensed consolidated balance sheet as of December 31, 1998 and
           the condensed consolidated statements of operations for the three and
           six month periods ended December 31, 1998 and 1997, and the condensed
           consolidated statement of cash flows for the six month periods ended
           December 31, 1998 and 1997, have been prepared by the Company and are
           unaudited. In the opinion of management, all adjustments (which
           include only normal recurring adjustments) have been made that are
           necessary to present fairly the financial position, results of
           operations and cash flows for all periods presented. It is suggested
           that these condensed consolidated financial statements be read in
           conjunction with the audited financial statements and notes thereto
           included in the Company's 1998 Annual Report to Stockholders. The
           results of operations for the period ended December 31, 1998 are not
           necessarily indicative of operating results for the full fiscal year.

     2.    In June 1998, the Financial Accounting Standards Board issued SFAS
           No. 133, "Accounting for Derivative Instruments and Hedging
           Activities". This statement establishes accounting and reporting
           standards requiring that derivative instruments (including certain
           derivative instruments embedded in other contracts) be recorded in
           the balance sheet as either an asset or liability measured at fair
           value. The Company is not presently involved in hedging activities or
           in using derivative instruments.

     3.    In June 1997, the Financial Accounting Standards Board issued SFAS
           No. 131, "Disclosure about Segments of an Enterprise and Related
           Information." SFAS No. 131 requires disclosure about operating
           segments in complete sets of financial statements and in 

                                      -6-
<PAGE>
 
           condensed financial statements of interim periods issued to
           shareholders. The new standard also requires that the Company report
           certain information about their products and services, the geographic
           areas in which they operate, and major customers. In addition, they
           issued SFAS No. 132 "Employer Disclosures about Pension and Other
           Post Retirement Benefits." These statements, both of which may be in
           effect for the Company for the year ended June 30, 1999, expand and
           modify disclosures and, accordingly will have no impact on the
           Company's Consolidated Balance Sheet or Statement of Operations.

     4.    Effective September 30,1998 the Company adopted SFAS No. 130
           "Reporting Comprehensive Income." This statement established
           methodology for reporting the types of income that would not be shown
           in a condensed consolidated statement of operations.

           December 31, 1998 and 1997, respectively but were not included in the
           computation of diluted earnings per share because they would have 
           been anti dilutive.

     6.    Subsequent Event:
           As previously announced on January 11, 1999, the Company completed
           the acquisition of certain assets of Banner Industries of New York,
           Inc., which manufacturers and distributes its products to catalog
           companies. The aggregate purchase price for the acquisition was
           $3,406,736 which will be paid for out of current working capital
           funds.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                      FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES
The Company's cash and cash equivalents increased during the six-month period
ended December 31, 1998 to $5,447,000 from $2,176,000 at June 30, 1998. The
increase this period was due mostly to a net increase in cash provided by
operating activities of $2,304,000, primarily from decreases in inventory and
prepaid expenses and other current assets, offset by a decrease in accounts
payable and other current liabilities. In addition, net cash provided by
investing activities totaling $937,000, mostly from maturities of securities
available for sale, added to the increase in cash and cash equivalents. The
Company believes that funds provided by operations, existing working capital and
the Company's current bank lines will be sufficient to meet foreseeable working
capital needs. There are no plans for significant capital expenditures in the
near term.

RESULTS OF OPERATIONS
Net sales were $13,134,000 and $28,779,000 during the three and six-month
periods ended December 31, 1998, compared to $21,369,000 and $40,699,000 in the
three and six-month periods ended December 31, 1997, respectively. The decrease
in sales for the quarter ended December 31, 1998 was primarily due to lower net
sales from the Company's Sleepwear division and its Children's division. Gross
profit was lower at 22.4% for the three-month period ended December 31, 1998
compared to the prior year comparable period of 25.6% due to lower Children's
division gross profit as well as much lower gross profit for the Company's
medium priced handbag business; both the result of discontinuing certain
inventory lines. For the six month period, net sales were lower mainly due to
overall lower anticipated shipping in two handbag divisions as well as lower
volume for the Company's Children's division, due to reduced demand for non-
branded merchandise. The gross profit of 25.1% for the six-month period ended
December 31, 1998 was slightly lower than the 25.4% gross profit achieved in the
prior year's six-month period, resulting, for the most part, from lower
Children's division gross profit.

Shipping, selling and administrative expenses decreased mainly due to lower
volume related expenses in the second quarter ended December 31, 1998 and for
this year's six-month period versus last year. As a percentage of net sales,
however, the three-month period increased from 24.5% to 27.9% and the six-month
period was higher by 3.8%, to 27.3%, from last year's six-month comparable
period due to the relative level of fixed costs.

                                      -9-
<PAGE>
 
Interest expense was much lower in both the second quarter and first six months
of fiscal 1999 versus the same fiscal 1998 periods, resulting from a lower
average level of borrowing and the utilization of available investment funds in
lieu of borrowing in the current fiscal year to date periods compared to last
year's same periods.

Interest income was lower by $5,000 and $29,000 in the second quarter and first
half of the current fiscal year, respectively, compared to the fiscal 1998
comparable periods due to the utilization of investment funds for current
working capital needs.

The loss before income taxes in the three-month and six-month periods as
compared to the earnings before taxes in the equivalent periods of fiscal 1998
was due mainly to the decrease in sales and gross profit which was not entirely
offset by lower shipping, selling and administrative expenses. Net loss for the
quarter and six month periods ended December 31, 1998 was $434,000 and $351,000,
respectively, compared to net earnings for the same periods last year of
$147,000 and $436,000.

YEAR 2000 COMPLIANCE
The Company has completed its assessment of the changes that are needed to make
its critical and other data processing systems Year 2000 compliant. The changes,
which include a combination of software modifications and upgrades and hardware
changes, have substantially been completed, with significant customer testing
underway. The company's internal target date to be fully compliant and tested is
May 1999. The Company has targeted May 1999 in an effort to provide it with
sufficient time to continue to test its systems, thereby minimizing the risks
associated with Year 2000 systems changes.

Existing data processing personnel are being utilized to implement Year 2000
changes. To date, total costs incurred have been approximately $8,000, with
total aggregate costs to become Year 2000 compliant not expected to exceed
$20,000.

Most of the Company's major customers have already indicated that they are or
will be Year 2000 compliant by the end of calendar year 1998. The Company is not
computer interdependent with its significant suppliers and, accordingly, does
not believe that the failure of suppliers to be Year 2000 compliant will pose
any significant risk to the Company's business operations. In any event, the
Company presently has and expects it will have alternative sources of supply if
existing vendors are unable to supply the Company if they are not Year 2000
compliant.

The foregoing contains forward looking statements based upon management's best
estimates concerning future events. Actual results could differ as a result of a
number of factors, including future costs of Year 2000 compliance, success of
