                        ENTEX INFORMATION SERVICES, INC.
              Notes to Condensed Consolidated Financial Statements

           1.  BASIS OF PRESENTATION

               The unaudited condensed consolidated financial statements
               included herein have been prepared by the Company pursuant to the
               rules and regulations of the Securities and Exchange Commission.
               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 such rules and regulations. However, in the opinion
               of management of the Company, the condensed consolidated
               financial statements include all adjustments, which consist only
               of normal recurring accruals, necessary to present fairly the
               financial information for such periods. These condensed
               consolidated financial statements should be read in conjunction
               with the consolidated financial statements and the notes thereto
               included in the Company's Annual Report on Form 10-K for the
               fiscal year ended June 27, 1999.

               Cash equivalents include short-term, highly liquid investments
               with a maturity of three months or less from the date of
               acquisition.

               Reclassifications of prior-year data have been made, where
               appropriate, to conform to the current year presentation.

               The results of operations for the three and six months ended
               December 26, 1999 are not necessarily indicative of the results
               to be expected for the fiscal year ending June 25, 2000.

           2.  COMPREHENSIVE INCOME

               Effective for the quarter ended September 27, 1998, the Company
               adopted Statement of Financial Accounting Standards No. 130,
               "Reporting Comprehensive Income" ("FAS 130"). Comprehensive
               income includes both net income and other comprehensive income.
               Included in other comprehensive income are foreign currency
               translation gains (losses). In accordance with the disclosure
               requirements of FAS 130, comprehensive loss for the three and six
               months ended December 26, 1999 and December 27, 1998 was $8,446
               and $7,849, and $34,795 and $48,566 respectively. Other
               comprehensive income (loss) for the three and six months ended
               December 26, 1999 and December 27, 1998 was $(8) and $(8), and $2
               and $31 respectively.

           3.  OBLIGATIONS RELATED TO DISCONTINUED OPERATIONS

               On May 10, 1999, the Company sold certain assets (inventory, land
               and building, and fixed assets) of its TAS Division to Compucom.
               The transaction was structured as an asset sale for cash. After
               giving effect to the proceeds of $137.4 million received by the
               Company for the transaction, and after accounting for the
               goodwill, inventories and fixed assets and deal-related expenses,
               the transaction resulted in a loss for ENTEX.

               The remaining obligations related to discontinued operations of
               $3.7 million at December 26, 1999 and $12.4 million at June 27,
               1999, respectively, relate to remaining severance payments ($1.5
               million and $6.3 million), future lease obligations ($1.0 million
               and $1.3 million), transition costs ($0 and $1.3 million) and
               allowance for uncollectible trade and vendor receivables ($1.2
               million and $3.5 million), and are classified as current
               liabilities in the consolidated balance sheet.

           4.  OBLIGATIONS RELATED TO RESTRUCTURING CHARGES

               In November 1998, the Company's Board of Directors authorized
               management actions that resulted in the reorganization of ENTEX's
               business to create two operating units: a TAS Division and a
               Services Division. The reorganization was intended to reduce
               costs and increase operational focus to respond to new market
               dynamics.

               As a result, a restructuring charge of $14 million ($12 million
               for discontinued operations and $2 million for continuing
               operations) was recorded during the second fiscal quarter ended
               December 27, 1998. The restructuring charge included $7 million
               to cover costs related to involuntary severance benefits in
               connection with a workforce reduction affecting approximately 450
               employees, all of whom left the Company at March 28, 1999. In
               addition, the restructuring charge included $7 million in
               connection with branch office consolidations, facilities
               reductions and other costs. As of June 27, 1999, $9.1 million of
               costs had been charged against the reserve. During the six months
               ended December 26, 1999, $3.1 million of costs were additionally
               charged against the reserve.

               The remaining liability of $1.8 million at December 26, 1999 and
               $4.9 million at June 27, 1999, respectively, primarily relates to
               future lease obligations, net of estimates of sublease income
               ($1.7 and $4.2 million) and remaining severance payments ($.1
               million and $.7 million), and is classified as current
               liabilities in the consolidated balance sheet.

           5.  SUBSEQUENT EVENT

               On January 24, 2000, the Company's Board of Directors authorized
               management actions that will result in the reorganization of
               ENTEX's business to create a more streamlined organization which
               will make the Company more competitive, increase the sales
               efforts and return the business to profitability.

                     Management's Discussion and Analysis of
                 Financial Condition and Results of Operations

THREE MONTHS ENDED DECEMBER 26, 1999 COMPARED TO THREE MONTHS ENDED DECEMBER 27,
1998

     Consolidated net loss for the three months ended December 26, 1999 was $8.4
million compared to consolidated net loss of $34.8 million in the three months
ended December 27, 1998. The results for the three months ended December 26,
1999 include income from discontinued operations of $3 million. Excluding this
income, the loss for the quarter ended December 26, 1999 would have been $11.4
million.The results for the three months ended December 27, 1998 include an
inventory charge, restructuring and non-recurring unusual items totaling $4.3
million and loss from discontinued operations of $12.9 million. Excluding these,
the net loss for the quarter ended December 27, 1998 would have been $17.6
million. The improved results are primarily driven by cost reductions in
selling, general and administrative expenses.

     Revenues: Revenues were $112.4 million for the three months ended December
26, 1999 as compared to $121.1 million for the three months ended December 27,
1998, a decrease of $8.7 million or 7.2%. The decline reflects softness in
consulting services as customers deferred non mandatory projects as a result of
concerns regarding Y2K.

     Gross margin: Gross margin was 21.7% or $24.3 million for the current
quarter as compared to 25.2% or $30.6 million for the three months ended
December 27, 1998. The decline is principally driven by revenue shortfall in
higher margin consulting services as well as the classification of direct
overhead costs for servicing large customers in cost of services provided in
1999 which costs were classified in SG&A in 1998.

     Selling, general and administrative expenses: Selling, general and
administrative expenses as a percentage of revenues decreased to 26.1% for the
quarter ended December 26, 1999 from 32.8% in the same period a year ago. For
the three months ended December 26, 1999, selling, general and administrative
expenses were $29.3 million as compared to $39.7 million for the quarter ended
December 27, 1998, a decrease of $10.4 million, primarily reflecting cost
reductions realized as a result of the reorganization announced in the second
quarter ended December 27, 1998 and classification of direct overhead costs of
servicing large customers to cost of services provided.

     Loss from operations: Loss from operations was $5.0 million for the three
months ended December 26, 1999 as compared to a loss from operations of $13.4
million in the quarter ended December 27, 1998. Excluding the inventory charge
of $1 million, the restructuring charge of $2 million and the non-recurring
unusual charge of $1.3 million, the loss in the quarter ended December 27, 1998,
would have been $9.1 million.

     Interest expense, net: Net interest expense decreased to $6.5 million for
the three months ended December 26, 1999 as compared to $9.0 million for the
three months ended December 27, 1998. The decrease is due to decreased working
capital needs as a result of the sale of the TAS Division, partially offset by
an increase in the IBM Credit Corporation ("IBMCC") borrowing rate.

     Other income: Other income for the quarter ended December 27, 1998,
represents a $575,000 gain on the early retirement of debt with maturity of less
than one year.

     Discontinued operations: Income from discontinued operations was $3.0
million for the three months ended December 26, 1999. This compares to loss from
discontinued operations of $12.9 million in the quarter ended December 27, 1998.
The income from discontinued operations of $3.0 million reflects better than
anticipated recovery on vendor receivables.

     Net income (loss): As a result of the factors mentioned above, the net loss
for the three months ended December 26, 1999 was $8.4 million as compared to net
loss of $34.8 million for the three months ended December 27, 1998.

                 Financial Condition and Results of Operations

SIX MONTHS ENDED DECEMBER 26, 1999 COMPARED TO SIX MONTHS ENDED DECEMBER 27,
1998

     Consolidated net loss for the six months ended December 26, 1999 was $7.8
million compared to consolidated net loss of $48.6 million in the six months
ended December 27, 1998. The results for the six months ended December 26, 1999
include income from discontinued operations of $5.8 million. Excluding this
income, the net loss for the six months ended December 26, 1999 would have been
$13.6 million. The results for the six months ended December 27, 1998 include an
inventory charge, restructuring charge and non-recurring unusual charge totaling
$4.3 million and loss from discontinued operations of $7.1 million, as
previously discussed. Excluding these, the net loss for the six months ended
December 27, 1998 would have been $37.2 million.

     Revenues: Revenues were $236.0 million for the six months ended December
26, 1999 as compared to $235.0 million for the six months ended December 27,
1998, an increase of $1.0 million or 0.4%. Revenue increase in the first fiscal
quarter due to increased demand from existing customers and the addition of new
large accounts was offset by revenue decline in the second fiscal quarter in
consulting services as customers deferred non mandatory projects as a result of
concerns regarding Y2K.

     Gross margin: Gross margin was 23.0% or $54.2 million for the six months as
compared to 26.1% or $61.3 million for the six months ended December 27, 1998.
The decline is principally due to classification of direct overhead costs for
servicing large customers in cost of services provided in 1999 which costs were
classified in SG&A in 1998.

     Selling, general and administrative expenses: Selling, general and
administrative expenses as a percentage of revenues decreased to 24.2% for the
six months ended December 26, 1999 from 34.2% in the same period a year ago. For
the six months ended December 26, 1999, selling, general and administrative
expenses were $57.0 million as compared to $80.4 million for the six months
ended December 27, 1998, a decrease of $23.4 million, primarily reflecting cost
reductions realized as a result of the reorganization announced in the second
quarter ended December 27, 1998 and classification of direct overhead costs of
servicing large customers to cost of services provided.

     Loss from operations: Loss from operations was $2.8 million for the six
months ended December 26, 1999 as compared to a loss from operations of $23.3
million in the six months ended December 27, 1998. The loss in 1998 includes the
inventory, restructuring and unusual charges as previously discussed. Excluding
these items, the loss for the six months ended December 27, 1998 would have been
$19.0 million.

     Interest expense, net: Net interest expense decreased to $12.1 million for
the six months ended December 26, 1999 as compared to $18.7 million for the six
months ended December 27, 1998. The decrease is due to decreased working capital
needs as a result of the sale of the TAS Division partially offset by higher
borrowing rates.

     Other income: Other income for the six months ended December 26, 1999 and
December 27, 1998 represents a $1.2 million and $575,000 gain on the early
retirement of debt with maturity of less than one year.

     Discontinued operations: Income from discontinued operations was $5.8
million for the six months ended December 26, 1999. This compares to loss from
discontinued operations of $7.1 million in the six months ended December 27,
1998. The income from discontinued operations of $5.8 million reflects better
than anticipated recovery on vendor receivables.

                 Financial Condition and Results of Operations

     Net income (loss): As a result of the factors mentioned above, the net loss
for the six months ended December 26, 1999 was $7.8 million as compared to net
loss of $48.6 million for the six months ended December 27, 1998.

LIQUIDITY AND CAPITAL RESOURCES

     The Company finances its operations principally with borrowings under a
working capital line of credit (the "IBM Working Capital Line of Credit") with
IBMCC. Cash provided by operating activities was $22.9 million for the six
months ended December 26, 1999 compared to $19.3 million for six months ended
December 27, 1998.

     Cash provided by operations during the six months ended December 26, 1999
resulted primarily from changes in operating assets and liabilities, principally
receivables of the TAS Division.

     Cash used in investing activities (capital expenditures) was $3.3 million
during the six months ended December 26, 1999 compared with $11.5 million during
the six months ended December 27, 1998.

     Cash used in financing activities was $27.6 million during the six months
ended December 26, 1999 compared to $2.4 million during the six months ended
December 27, 1998. During the six months ended December 26, 1999, cash received
from the winddown of TAS Division receivables was used to pay down interest
bearing debt. During July 1998, the Company issued $100 million of 12 1/2%
Senior Subordinated Notes due 2006. The net proceeds were used to repay
outstanding indebtedness of the Company, resulting in an increase in working
capital of approximately $74 million.

     As of December 26, 1999, the Company's primary source of liquidity
consisted of financing provided by IBMCC . The IBMCC Working Capital Line of
Credit is asset based, and provides for borrowings of up to $100 million subject
to available collateral. The interest bearing portion was $72.7 million as of
December 26, 1999. The amount of available borrowings and such line of credit
expire on July 31, 2001, and can be reduced or terminated by IBMCC upon 60 days'
prior notice. Amounts outstanding under the IBMCC Working Capital Line of Credit
bear interest at LIBOR plus 3.00% (8.6% at December 26, 1999). On December 21,
1999, the Company executed an amendment to the IBM Working Capital Line of
Credit to extend to March 31, 2000 its existing overadvance from its previously
scheduled termination date of December 21, 1999. The overadvance permits the
Company to borrow up to $20 million in excess of what would otherwise have been
allowed under the collateral formula in the IBM Working Capital Line of Credit.
The overadvance bears interest at LIBOR plus 5.5%, (11.1% at December 26,1999).
IBMCC also agreed to modifications of the financial covenants in the IBM Working
Capital Line of Credit requested by the Company. The Company is in negotiations
with IBMCC for an extension of such overadvance beyond March 31, 2000 if
required. Simultaneously with execution of the amendment of the IBM Working
Capital Line of Credit, the Company's principal stockholder, Mr. Dort A. Cameron
III, guaranteed up to $20 million of the Company's obligations to IBMCC, and
purchased from IBMCC an outstanding option to purchase from Mr. Cameron
1,851,850 shares of the Company's common stock. Mr. Cameron initially granted
this option to IBMCC in 1993. The purchase price for the option was $3 million
in cash, payable not later than March 31, 2000, and an additional amount equal
to the excess, if any, of 1,851,850 multiplied by the highest per-share price of
the Company's common stock obtained by Mr. Cameron or any of his affiliates
during the period ending one year after the execution of the option purchase
agreement over the initial $3 million amount. The additional amount, if any, is
payable upon the consummation of any subsequent transactions in which more than
50% of the Company's common stock is sold.

                 Financial Condition and Results of Operations

If no such sale occurs within one-year period, the original option will be
reinstated with the aggregate exercise price increased by $3 million.

     These transactions provide the Company with continued access to $20 million
in liquidity under the IBM Working Capital Line of Credit that otherwise would
have been unavailable and will enable the Company to support its ongoing
business and to fund its debt service obligations in the near term. The
continued availability of these working capital resources will also provide
additional time for the Company to complete the repositioning of its business to
one providing services only. The Company is in the process of pursuing various
alternatives to raise additional funds through public or private equity or debt
financing or from other sources to meet its liquidity needs. However, there can
be no assurance that the Company will be able to raise such additional funding.

     The IBMCC Financing Agreement contains restrictive covenants with respect
to maintenance of minimum tangible net worth, current ratio and fixed charge
coverage. In addition, the IBMCC Financing Agreement prohibits the Company from
paying cash dividends on common stock. At December 26, 1999, the Company was in
compliance with such covenants.

     At December 26, 1999, the Company had no material commitments other than
obligations under its credit facilities, term notes and operating lease
facilities.

YEAR 2000 UPDATE

     Operations of the Company have not been impacted to date by any Year 2000
related issues. To mitigate any future risk the Company's Year 2000 Team will
remain intact through March 31, 2000 to respond to any issues that may arise.

ITEM 3.        QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT
               MARKET RISK

               The Company is exposed to interest rate risk primarily through
               its asset based financing agreement. The Company utilizes these
               borrowings to meet its working capital needs. As of December 26,
               1999, the Company had borrowings of approximately $72.7 million
               outstanding, which have a variable interest rate of 8.6%. Using a
               yield to maturity analysis and assuming an increase in interest
               rate on these borrowings of 25 basis points, future annual cash
               flows would be effected by $.2 million. All other borrowings are
               at fixed interest rates and therefore market interest rate
               variability does not impact their future cash flows.

               Currently, the Company does not enter into financial instruments
               for trading or other speculative purposes or to manage interest
               rate exposure.
