NOTE 3 - LONG - TERM DEBT AND WARRANTS

In August 1997, the Company obtained an additional term loan from its principal
senior lender with cash proceeds of $750,000. The new term loan bears interest
at 3% payable in-kind and is due in August 2002. In connection with this
transaction, the Company also issued warrants and repriced certain existing
warrants held by the lender. The total cash proceeds received were allocated
based on fair value to the new term loan and the related warrants, resulting in
a warrant value and equivalent debt discount of $609,900. The related debt
discount is amortized over the loan term.

In December 1997, the Company obtained an over-advance note of its revolving
credit facility under which the Company may borrow up to an additional
$1,300,000. Each advance under the new facility is subject to the lender's prior
approval. To date, the Company has drawn $800,000 however, further advances have
been denied. All advances will bear interest at 12% of which 3% will be payable
monthly in arrears and 9% may either be paid monthly or, at the Company's
option, deferred and paid (with interest on the deferred amount) at maturity.
All principal and unpaid interest is due December 17, 1999. The Company also
repriced certain existing warrants held by the lender which increased the
warrant value and related debt discount by $181,900.

The Company is currently in default of all debt with its principal lender. See
further discussion under "Management's Discussion and Analysis - Liquidity and
Sources of Capital."

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS:

RESULTS OF OPERATIONS

Net sales decreased 34.8% in the third quarter ended April 30, 1998 to
$3,477,430, a decrease of $1,853,136 over the same period of the prior year. Net
sales for the first nine months were $10,728,810, a decrease of 38.0% over the
same period of the prior year. Most of the quarterly and nine month net sales
decrease was attributed to the mutual cancellation of a food service contract at
the end of the third quarter of the prior fiscal year.

Gross profit as a percent of net sales in the third quarter was 42.8% versus
29.6% in the same period of the prior year. The increase in gross profit as a
percent of net sales reflects the impact of the higher margin from the branded
product sales, which were a higher portion of the sales mix in fiscal 1998, and
the manufacturing cost reduction programs implemented during fiscal 1998 to
lower the Company's break-even point. Manufacturing cost reduction measures have
included employee layoffs, decreased management salaries and personnel along
with improved manufacturing efficiencies. However, due to the lower sales
volume, gross profit decreased to $1,486,998 from $1,578,438 for the same period
of the prior year. Gross profit for the first nine months was $4,151,312, or
38.7% of net sales, versus 35.0% for the same period of the prior year.

For the third quarter ended April 30, 1998, distribution expense totaled
$265,793 or 7.6% of net sales versus 7.2% in the prior year. Distribution
expense for the nine months ended April 30, 1998 was 8.2% of net sales versus
7.6% for the same period of the prior year.

Selling, general and administrative expenses in the third quarter of 1998 were
$915,388, a decrease of $526,407 or 36.5% from the same period of the prior
year. The decrease reflects reduced salaries, travel, advertising, trade
allowance, and promotions. The lower salary expense is attributed to the
reduction of executive and management salaries and decreased numbers of
management personnel. Advertising, trade allowance, promotion and slotting
expense decreased 38.0% to $482,543 from $777,669 for the same period of the
prior year, while net branded sales, which account for the majority of such
costs, remained essentially unchanged. The Company has instituted a program of
selective advertising and promotional spending that focuses on market
penetration and profitability. In the first nine months, selling, general and
administrative expenses were $3,108,386, a decrease of $1,343,196 from the same
period of the prior year.

For the third quarter ended April 30, 1998, income from operations was $305,817
as compared to a loss from operations over the same period of the prior year of
$66,519 (which excluded an inventory adjustment of $181,239 related to the food
service contract.) Income from operations for the third quarter of 1998 also
improved $270,390 from the $35,427 income from operations in the second quarter
of fiscal 1998. This reflects the continued impact of the Company's aggressive
cost reduction steps. The improvement was accomplished with sales being
approximately the same as the second quarter of the current fiscal year.
However, these results are not necessarily indicative of the results that may be
expected in the future, especially in light of the fact we are entering into the
summer months and the consumer preference is mainly for hot dog and hamburger
rolls rather than bagels.

Interest expense in the third quarter ended April 30, 1998 increased $212,130
from $136,736 for the same period of the prior year and interest expense for the
nine months ended April 30, 1998 was $1,019,605 versus $395,290 for the same
period of the prior year. The principal reason for the increase is due to the
fact that there was no interest capitalized for the three and nine months ended
April 30, 1998, whereas, in the prior year interest was capitalized due to the
plant expansion project.

As a result of the factors described above, net loss for the third quarter ended
April 30, 1998 was $45,193 compared to a net loss of $377,355 for the same
period of the prior year. The net loss for the first nine months was $865,854
compared to a net loss of $94,031 for the same period of the prior year.


LIQUIDITY AND SOURCES OF CAPITAL

Cash used by operating activities was $991,504 for the nine months ended April
30, 1998, compared to cash provided by operating activities of $1,807,761 for
the same period of the prior year. The net loss and impact of an increase in
working capital accounts for this change.

Cash used by investing activities was $365,404 for the nine months ended April
30, 1998, a decrease of $2,335,338 over the same period of the prior year. The
primary uses of investment funds was payment for completing certain plant
projects.

Cash provided by financing activities was $1,395,500 for the nine months ended
April 30, 1998, primarily representing the proceeds from long term debt and
warrants.

In December 1997, the Company entered into agreements with its principal lender
pursuant to which (a) the lender waived all existing defaults under the credit
agreements, (b) the financial covenants were amended by removing existing
covenants and substituting a covenant requiring the Company to maintain certain
monthly levels of cash flow, and (c) the lender established a new credit
facility pursuant to which the Company may borrow up to an additional
$1,300,000. Each advance under the new facility is subject to the lender's prior
approval. To date, the Company has drawn $800,000. However, all advances
requested since January 1998 have been denied. All advances bear interest at
12%, of which 3% is payable monthly in arrears and 9% may either be paid monthly
or, if not paid, deferred and paid (with interest on the deferred amount) at
maturity. All principal and unpaid interest is due on December 17, 1999. Through
April 1998 the Company has complied with the defined cash flow covenants as set
forth by the lender.

The Company has not made scheduled monthly interest payments to the lender for
the period January through May 1998. The Company has experienced losses and
resulting cash flow difficulties which are a result of the factors described
under "Management's Discussion and Analysis - Results of Operations," primarily
the reduction in sales as a result of the mutual cancellation of a substantial
food service contract during the third quarter of fiscal 1997.

In order to manage its working capital, the Company has routinely extended
payment of certain trade creditors and trade payables beyond standard terms. To
date, this practice has not adversely affected the delivery of goods from
suppliers. The Company expects to continue the practice of extending payment of
payables over the near term. In the third quarter of fiscal 1998 the Company did
not extend the payment terms for its major suppliers.

                                  Page 8 of 11

The Company has implemented a number of steps to maintain adequate cash flow as
reported in Form 10-KSB for the year ended July 31, 1997. The Company has
engaged a management consulting firm to review and recommend ways to improve
performance and cash flow. As a result, the Company has implemented a number of
measures to improve manufacturing, operating direct labor efficiencies, and to
reduce selling expenses, salaried personnel and salaries of corporate officers.
These measures have significantly reduced the Company's operating costs and
improved its cash flow, as noted under "Results of Operations." The Company
continues to evaluate and implement, where economically feasible, additional
programs to reduce costs. The Company also continues to work with its
consultants on exploring possible additional approaches to improving the
Company's financial situation including possible mergers and acquisitions.

The Company and its management consultant also are continuing to evaluate
various possible alternatives to maximize the use and value of the Company's
capital and other assets. This review, when complete, could result in the sale
and/or write down of certain assets. If necessary, appropriate adjustments to
long-lived assets in accordance with FASB Statement 121, or any other necessary
accounting adjustments, would be recognized upon completion of the review which
is anticipated to be completed in the fourth quarter of fiscal 1998.

There can be no assurance as to the outcome of the current constraint on the
Company's cash flow. All advance requests since January 1998 under the over
advance note have been denied. The Company believes in the fourth quarter of
fiscal 1998 that cash flow will be more constrained due to lower sales volume
(seasonality) and increased promotion expenses, but should be sufficient to
allow the Company's liquidity needs to be met except for monthly interest
payments. At this time the Company does not intend to make any further interest
payments to its pricipal lender during the current fiscal year. The liquidity
needs include trade obligations continuing to be paid on extended payment terms
as noted above during the fourth quarter of fiscal 1998.

On May 19, 1998, the Company's lender gave written notice that the Company was
in default of its loan payments and that it would pursue its legal remedies and
the lender has demanded payment for all amounts due under the loan agreement. To
date, the lender has not attempted to implement any of its legal remedies, but
there can be no assurance it will not do so in the future.

The Company realizes that its capital structure must change and is discussing
possible approaches with its current lender. The outcome of these discussions
cannot be predicted at this time. The Company continues to evaluate and, where
appropriate, pursue other alternatives to restructure its debt, either with the
current lender or another group. However, there can be no assurance that the
Company will be successful in its efforts.
