                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

A.  Pursuant to the rules and regulations of the Securities and Exchange
Commission, certain financial information has been condensed and certain
footnote disclosures have been omitted.  Such information and disclosures are
normally included in financial statements prepared in accordance with generally
accepted accounting principles.

These condensed financial statements should be read in conjunction with the
financial statements and notes thereto in the Company's latest report on Form
10-K.

The financial statements as of April 30, 1998 and for the three and six month
periods then ended are unaudited; however, in the opinion of management, such
statements include all adjustments (consisting solely of normal and recurring
adjustments) necessary or present fairly the financial information included
therein.

B.  The consolidated statements of operations for the three and six months 
ended April 30, 1998, are not necessarily indicative of the operating results
to be expected for the full year.

C.  The Company adopted SFAS No. 128, "Earnings per Share" in November 1997.
This statement, which replaces APB Opinion No. 15, "Earnings per Share",
establishes simplified accounting standards for computing earnings per share
("EPS") and makes them comparable to international EPS standards.

Basic EPS is computed by dividing net earnings by the weighted-average number
of common shares outstanding during each period of 24,909,616 shares and
24,822,798 shares for 1998 and 1997, respectively.  Diluted EPS is computed by
dividing net earnings by the weighted-average number of common shares and
common stock equivalents outstanding during the period of  25,167,060 and
24,863,635 for 1998 and 1997, respectively.  All prior-period EPS amounts
presented conform to the provisions of SFAS No. 128.

D.  On January 14, 1998, the Company signed a definitive agreement to exchange
the assets of selected TCA Cable Partners systems in Oklahoma, serving
approximately 15,000 subscribers, for  the assets of selected Cable ONE systems
in Texas, serving approximately 14,000 subscribers.  Cable ONE is a Washington
Post subsidiary.  The exchange is expected to close on June 15, 1998.

E.  On February 2, 1998, the Company formed a partnership, TCA Cable Partners
II (the "TCI Transaction") with TCI American Holdings IV, L.P. (the "TCI
Affiliate"), an affiliate of TCI Communications, Inc.  The Company contributed
certain cable systems in Texas and New Mexico serving approximately 155,000
subscribers and $46.6 million in unsecured debt and the TCI affiliate
contributed its cable systems in north Texas and western Louisiana, serving
approximately 150,000 subscribers and $247.9 million in unsecured debt, in
exchange for an 80% and 20% partnership interest, respectively, in TCA Cable
Partners II. The cable systems contributed by the Company and the TCI
Affiliate are each valued at approximately $315 million. The Company financed
the TCI Transaction with a portion of the proceeds from a $150 million increase
in the Company's primary credit facility and the issuance of $200 million in
public debt. TCA Cable Partners II will be consolidated in the financial
statements of the Company and 20% of the estimated fair value of TCA Cable
Partners II net assets will be recorded by the Company as a redeemable minority
interest at the acquisition date. The TCI Affiliate has the right to require
the Company to purchase the TCI Affiliate's 20% partnership interest at fair
market value beginning February 2003 through February 2023 (the "Put and Call
Period"), the termination date of the partnership agreement.  The Company has a
corresponding right to require the TCI Affiliate to sell its 20% partnership
interest in TCA Cable Partners II to the Company at fair market value during
the Put and Call Period.  TCA Cable Partners II  will be managed by the
Company.  At the closing of the TCI Transaction, the Company  served
approximately  860,000 subscribers. In connection with the TCI transaction, the
Company recorded a deferred tax liability and a corresponding intangible asset
of $53 million.                                          

F.  On February 2, 1998, the Company issued $200 million in bonds with a coupon
of 6.53% to finance the TCI transaction.  On July 24, 1997, the Company
filed a shelf registration with the SEC for a public debt offering of up to
$300 million. The bondholders have the option to require the Company to
repurchase the bonds on the tenth anniversary date at face value.

G.  On April 1, 1998, the Company acquired Web International, Inc., doing
business as Internet Tyler, an internet service provider serving the Tyler,
Texas area.  The Company issued 19,242 shares of common stock valued at
$962,100 and paid approximately $260,000 in cash.

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

THREE MONTHS ENDED APRIL 30, 1998 COMPARED TO THREE MONTHS ENDED APRIL 30,
1997.

       REVENUES.  Revenues increased by $21.6 million, or 28.8%, during the
three months ended April 30, 1998 compared to the three months ended April 30,
1997.  Management attributes approximately $2.4 million, or 11.3%, of the
revenue increase to internal growth in cable systems, $16.3 million, or 75.5%
to cable system acquisitions, $3.3 million, or 15.1%, to internal growth in the
Company's advertising insertion business, $0.6 million, or 2.8% to the
acquisition of two internet service providers and $0.1 million, or 0.4% to
internal growth in the Company's internet access business.  These increases in
revenue were offset by a decrease of $1.1 million, or 5.1% resulting from the
Company's sale of its long distance business.

       Revenues from basic and expanded basic cable television subscriptions
increased $15.1 million, or 31.6%, during the three months ended April 30, 1998

primarily due to the properties contributed by the TCI Affiliate in the TCI
Transaction.

1997 as a result of a $247.9 million increase in debt from the TCI Transaction,
offset by a net repayment of debt of $9.9 million.  The Company's weighted

1998 compared to 699,684 at April 30, 1997.  The increase in subscribers
resulted from 148,436 additional subscribers acquired in the TCI Transaction
and  19,435 subscribers, or a 2.8% increase, from internal growth.

LIQUIDITY AND CAPITAL RESOURCES

       The Company has historically been able to meet its current and long-term
liquidity and capital requirements, including dividends and fixed charges,
through cash flow generated from operating activities, existing cash, bank
lines of credit, and other external financing.

       Net cash flow from operating activities increased 21.7% to $62.0 million
in 1998 from $50.9 million in 1997.  The increase was principally due to cable
system acquisitions and internal growth in cable operations and advertising..

       At April 30, 1998, the Company had $231.0 million in borrowings under
its bank credit facilities.  The Company had $190.0 million borrowed under its
primary credit facility which provides for up to $350 million in borrowings by
the Company and expires on January 31, 2003.  The primary credit facility
provides for interest to be paid quarterly at prime or LIBOR plus an applicable
margin .  At April 30, 1998 the Company also had $41.0 million borrowed under
additional credit facilities with two banks.  The additional bank credit
facilities provide for up to $40.0 million and $4.0 million in borrowings by
the Company and expire June 1999 and April 1999, respectively.  During the six
months ended April 30, 1998 and  1997, the Company borrowed approximately
$605.6 million and $61.7 million respectively and repaid approximately $373.6
million and $47.9 million, respectively.  In the six months  ended April
30,1998, the Company's bank debt carried a weighted average interest rate of
6.6%.

       On September 27, 1989 the Company completed a $100 million private
placement of debt securities due August 1999 bearing an interest  rate of 9.0%.
The terms of the securities call for the repayment of principal in semiannual
installments beginning February 1993.  In addition on June 23, 1995, the
Company completed a $100 million private placement of debt securities due June
2005 bearing an interest rate of 7.26%.  The terms of these securities call for
the repayment of principal in annual installments beginning in June 1999.

       The Company believes that EBITDA, defined as earnings before interest,
taxes, depreciation and amortization, and related measures of cash flow serve
as important financial analysis tools for measuring and comparing cable
television companies in several areas , such as liquidity, operating
performance and leverage.  The Company's  ratio of indebtedness to EBITDA was
3.4x and 2.6x for the three months ended April 30, 1998 and 1997, respectively.
The Company's interest coverage ratio, defined as the ratio of EBITDA to total
interest expense, was 6.1x and 5.9x for the three months ended April 30, 1998
and 1997 respectively.

       The Company's capital expenditures totaled $26.5 million and  $23.9
million in the six months ended April 30, 1998 and 1997, respectively.  Funds
were applied primarily toward the upgrade of the Company's cable systems and
the purchase of subscriber equipment, including converter boxes.  The Company
has principally financed its capital






                                       10
<PAGE>   11

expenditures through funds generated by its operating activities, and to a
lesser extent, bank borrowings and private placements of debt securities.  The
Company expects to continue the upgrade of its cable systems in 1998 and
anticipates total capital expenditure requirements in fiscal 1998 to be
approximately 10% more than in 1997.

       As a part of the Company's growth strategy the Company has been actively
acquiring cable systems which meet the Company's acquisition criteria.  The
Company has funded its acquisitions through internally generated funds, private
placements of debt securities, bank financing and capital contributions from DR
Partners and TCI.  The Company anticipates the acquisitions of additional
systems in selected markets in the future.

       The Company paid dividends on its common stock totaling approximately
$4.0 million, or $0.16 per share  in the three months ended April 30, 1998 and
1997, respectively.

       The Company believes that net cash provided by operating activities,
borrowings under its bank credit facilities and the Company's ability to obtain
financing will provide adequate sources of short-term and long-term liquidity
in the future.

       On February 2, 1998, the Company formed a partnership, TCA Cable
Partners II ( the "TCI Transaction"),  with TCI American Holdings IV, L.P.( the
"TCI Affiliate") , an affiliate of  TCI Communications Inc.  The Company
contributed certain cable systems in Texas and New Mexico serving approximately
155,000 subscribers and  $46.6 million in unsecured debt and the TCI Affiliate
contributed its cable systems in north Texas and western Louisiana, serving
approximately 150,000 subscribers and $247.9 million in unsecured debt, in
exchange for an 80% and 20% partnership interest, respectively, in TCA Cable
Partners II.  The cable systems contributed by the Company and the TCI
Affiliate are each valued at approximately $315 million. The Company financed
the TCI Transaction with a portion of the proceeds from a $150 million increase
in the Company's primary credit facility and the issuance of $200 million in
public debt.  TCA Cable Partners II will be consolidated in the financial
statements of the Company and 20% of the estimated fair value of TCA Cable
Partners II net assets will be recorded by the Company as a redeemable minority
interest at the acquisition date. The TCI Affiliate has the right to require
the Company to purchase the TCI Affiliate's 20% partnership interest at fair
market value beginning February 2003 through February 2023 (the "Put and Call
Period"), the termination date of the partnership agreement.  The Company has a
corresponding right to require the TCI Affiliate to sell its 20% partnership
interest in TCA Cable Partners II to the Company at fair market value during
the Put and Call Period.  TCA Cable Partners II  will be managed by the
Company.  At the closing of the TCI Transaction, the Company  served
approximately  860,000 subscribers. In connection with the TCI transaction, the
Company recorded a deferred tax liability and a corresponding intangible asset
of $53 million.                                          

       On July 24, 1997, the Company filed a shelf registration with the SEC
for a public debt offering of up to $300 million.  On February 2, 1998, the
Company issued $200 million in bonds with a coupon of 6.53% and a 10 year put
to finance the TCI Transaction.  The Company has received a rating of BBB+ from
Standard & Poor's and Baa2 from Moody's.  In August 1997, the Company entered
into treasury lock transactions ( the "Treasury Locks") with a notional amount
of $100 million as a hedge against interest rate changes prior to the closing
of the debt offering.  In January 1998, the Treasury Locks were terminated at a
cost of $7.9 million.  The cost will be amortized over the term of the public
debt as an interest rate yield adjustment.
