                            CALLOWAY'S NURSERY, INC.
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. BASIS OF PRESENTATION

     The interim financial statements contained herein have been prepared by
Calloway's Nursery, Inc. (the "Company") pursuant to the rules and regulations
of the Securities and Exchange Commission. In the opinion of management, all
adjustments considered necessary for a fair presentation of the financial
position at June 30, 1998, and the results of operations and cash flows for the
nine-month and three-month periods ended June 30, 1998 and 1997 have been made.
Such adjustments are of a normal recurring nature.

     Because of seasonal and other factors, the results of operations for the
nine-month and three-month periods ended June 30, 1998 and cash flows for the
six-month period ended June 30, 1998 are not necessarily indicative of expected
results of operations and cash flows for the fiscal year ending September 30,
1998.

     Certain information and footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted pursuant to the rules and regulations of the
Securities and Exchange Commission. Accordingly, these financial statements
should be read in conjunction with the audited financial statements and related
notes of the Company for the fiscal year ended September 30, 1997 included in
the Company's Form 10-K.

2. EARNINGS PER SHARE

     In February 1997 the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128 Earnings Per Share, ("SFAS 128"). SFAS
128 simplifies the standards for computing earnings per share ("EPS") previously
found in Accounting Principles Board Opinion No. 15, Earnings Per Share, ("APB
15"), and make them comparable to international EPS standards. SFAS 128 replaces
the presentation of primary EPS with a presentation of basic EPS. Basic EPS
excludes dilution and is computed by dividing income available to common
shareholders by the weighted average number of common shares outstanding for the
period. Diluted EPS reflects the potential dilution that could occur if
securities or other contracts to issue common stock were exercised or converted
into common stock or resulted in the issuance of common stock that then shared
in the earnings of the entity. Diluted EPS is computed similarly to fully
diluted EPS pursuant to APB 15. SFAS 128 also requires presentation of both
basic and diluted EPS on the face of the income statement for entities with
complex capital structures and a reconciliation of the numerator and denominator
of the basic EPS computation to the numerator and denominator of the diluted EPS
computation. SFAS 128 is effective for financial statements issued for periods
ending after December 15, 1997, including interim periods; earlier application
is not permitted. SFAS 128 requires restatement of all prior-period EPS data
presented.

Quarter Ended June 30, 1998 Compared with Quarter Ended June 30, 1997

     The Company's net sales hit record levels and pre-tax operating income rose
from $2.7 million to $2.8 million. Net income for the 1998 quarter was lower due
to an income tax provision of $1.1 million in 1998, compared to zero income tax
provision for the comparable quarter in 1997. The tax provision in 1998 was
recorded due to the adjustment of the valuation allowance recorded during the
fourth quarter of fiscal 1997.

     Net sales increased by 15% to $15,047,000 for the quarter ended June 30,
1998 from $13,108,000 for the quarter ended June 30, 1997. Same store (13
stores) sales were up 14% to $13,155,000 for the quarter ended June 30, 1998
from $11,497,000 for the quarter ended June 30, 1997. Sales were particularly
strong early in the quarter due to the Company's grand opening of its new
prototype retail store in April and to an expanded presentation of merchandise.
However, demand for living plants and related garden products in the Dallas-Fort
Worth area was lower in the later part of the season in 1998.

     Gross profit increased by 11% from $6,254,000 for the quarter ended June
30, 1997 to $6,964,000 for the quarter ended June 30, 1998. Gross margins
declined to 46% for the quarter ended June 30, 1998 from 48% for the quarter
ended June 30, 1997. The gross margin reduction resulted from higher late-season
markdowns in 1998 than in 1997.

     Operating expenses increased by 12% from $2,454,000 for the quarter ended
June 30, 1997 to $2,743,000 for the quarter ended June 30, 1998, primarily due
to increased payroll and related expenses.

     Occupancy expenses increased by 21% from $583,000 for the quarter ended
June 30, 1997 to $708,000 for the quarter ended June 30, 1998. The increase was
due to the 1997 rent reductions negotiated by the Company for certain of its
retail stores, which resulted in a benefit recognized during the 1997 quarter
that did not recur during the 1998 quarter.

     Advertising expenses increased by 22% from $510,000 for the quarter ended
June 30, 1997 to $621,000 for the quarter ended June 30, 1998. The increase was
primarily due to increased advertising in newspapers, television and radio.

     Other (net) expenses increased by 338% from $18,000 for the quarter ended
June 30, 1997 to $79,000 for the quarter ended June 30, 1998. The increase was
primarily due to interest expense on the increased long term debt in 1998 as
compared to 1997, partially offset by slightly lower depreciation expense for
the three months ended June 30, 1998 than for the three months ended June 30,
1997.

Nine months Ended June 30, 1998 Compared with Nine months Ended June 30, 1997

     The Company's net sales rose by 5%; however, pre-tax operating income
declined from $1,498,000 to $1,077,000. Net income for the 1998 period was lower
still, due to an income tax provision of $431,000 in 1998, compared to zero
income tax provision for the comparable period in 1997. The tax provision in
1998 was recorded due to the adjustment of the valuation allowance recorded
during the fourth quarter of fiscal 1997.

     Net sales increased by 5% to $23,769,000 for the nine months ended June 30,
1998 from $22,672,000 for the nine months ended June 30, 1997. Same store (13
stores) sales were up 6% to $20,899,000 for the nine months ended June 30, 1998
from $19,783,000 for the nine months ended June 30, 1997. The Company's enjoyed
strong sales increases during the peak of its spring selling season in 1998.
However, demand for living plants and related garden products in the Dallas-Fort
Worth area was lower in both the early and later parts of the season in 1998.

     Gross profit increased by 4% from $10,688,000 for the nine months ended
June 30, 1997 to $11,115,000 for the nine months ended June 30, 1998. Gross
margins of 47% were achieved for both of the nine-month periods ended June 30,
1998 and 1997.

     Operating expenses increased by 11% from $5,781,000 for the nine months
ended June 30, 1997 to $6,393,000 for the nine months ended June 30, 1998
primarily due to increased payroll expenses.

     Occupancy expenses increased by 1% from $2,082,000 for the nine months
ended June 30, 1997 to $2,112,000 for the nine months ended June 30, 1998. The
increase was due to the 1997 rent reductions negotiated by the Company for
certain of its retail stores, which resulted in a benefit recognized during the
1997 period that did not reoccur during the 1998 period.

     Advertising expenses increased by 7% from $1,138,000 for the nine months
ended June 30, 1997 to $1,222,000 for the nine months ended June 30, 1998. The
increase was primarily due to increased advertising in newspapers, television
and radio.

     Other (net) expenses increased by 64% from $190,000 for the nine months
ended June 30, 1997 to $311,000 for the nine months ended June 30, 1998 The
increase was primarily due to interest expense on long term debt that was higher
in 1998 than during the comparable period in 1997.

CAPITAL RESOURCES AND LIQUIDITY

     Cash flows provided by operating activities were $1,931,000, compared to
cash flows provided by operations of $4,428,000 for the nine months ended June
30, 1998. The reduced cash flows from operations for the period resulted from:

     1.   Lower pre-tax income for the period;

     2.   Higher inventory levels in the retail stores;

     3.   Investment in work-in-process and supplies inventories at Miller Plant
          Farms, the Company's newly acquired nursery production facility.

     In October 1997 the Company purchased land and constructed a new retail
store location in Fort Worth, Texas. The purchase and construction were
partially financed with an interim construction loan from a financial
institution. The Company has obtained a commitment from the financial
institution to provide permanent financing with a long-term note payable, and
expects to convert the interim construction loan into a permanent loan during
the fourth quarter of fiscal 1998. The new store opened on April 10, 1998. The
amount outstanding at June 30, 1998 was $1,125,000, and is reflected in the June
30, 1998 Condensed Consolidated Balance Sheet as long-term debt.

     The Company believes it has adequate working capital and lines of credit to
provide liquidity during future off-seasons.

BALANCE SHEET

     Cash and cash equivalents at June 30, 1998 were lower at June 30, 1998 than
at June 30, 1997 due to the factors noted above (See "Capital Resources and
Liquidity").

     Inventories at June 30, 1998 were higher at June 30, 1998 than at June 30,
1997 due to the factors noted above (See "Capital Resources and Liquidity").

     Deferred income taxes (current and long-term) at June 30, 1998 totaled
$592,000 compared to $34,000 at June 30, 1997. The increase was due to the
Company's recognition, in the fourth quarter of fiscal 1997, of the tax benefits
associated with net operating loss carryforwards generated in prior years, and
to a change in the valuation allowance for deferred tax assets, reduced by the
income tax provision of $431,000 for the nine month period ended June 30, 1998.

     Property and equipment at June 30, 1998 was higher than at June 30, 1997
due to the new store construction noted above (See "Capital Resources and
Liquidity"), as well as the acquisition of the nursery production facility
during the fourth quarter of fiscal 1997.

     Accounts receivable, accounts payable, and accrued expenses vary seasonally
along with sales activity. Accounts receivable at June 30, 1998 was not
significantly changed from the comparable period in 1997. Accounts payable at
June 30, 1998 was lower than for the comparable period in 1997. Since
approximately $700,000 of inventory sold in the retail stores was produced by
the Company's wholly owned nursery production facility, there were no accounts
payable associated with that merchandise. Accrued expenses were lower in 1998
than in 1997 since smaller bonus accruals were made due to the reduced pre-tax
operating profits.

     Prepaids and other assets (current and long-term), goodwill, and deferred
rent payable do not typically fluctuate seasonally. The amounts at June 30, 1998
were not significantly changed from the comparable period in 1997.

     Long-term debt (including current portion) at June 30, 1998 was $2,983,000
compared to $545,000 at June 30, 1997. The increase was due to long-term debt
incurred during 1997 and the new store construction noted above (See "Capital
Resources and Liquidity").
