TRIAX MIDWEST ASSOCIATES, L.P. NOTES TO FINANCIAL STATEMENTS December 31, 1997 and 1998 and June 30, 1999 (All amounts related to the June 30, 1998 and 1999 periods are unaudited) (1) THE PARTNERSHIP Organization and Capitalization Triax Midwest Associates, L.P. (the "Partnership") is a Missouri limited partnership originally formed for the purpose of acquiring, constructing and operating cable television properties, located primarily in Indiana, Illinois, Iowa, Minnesota and Wisconsin. The Partnership was capitalized and commenced operations on June 1, 1988. The non-managing general partner is Triax Cable General Partner, L.P. ("Triax Cable GP"), a Missouri limited partnership. The general partner of Triax Cable GP is Midwest Partners, L.L.C. The managing general partner of the Partnership is Triax Midwest General Partner, L.P., a Delaware limited partnership, and its general partner is Triax Midwest, L.L.C. Partnership Recapitalization On August 30, 1996 (the "Contribution Date"), the Partnership completed a recapitalization of the Partnership in which new credit facilities were put in place (Note 4), additional partnership interests were issued and selected partnership interests were redeemed. Under the terms of a partnership amendment and other related documents, the Partnership received approximately $50.3 million in cash from new limited partners in exchange for limited partnership interests ("New Cash Partners"). Approximately $38.3 million in cash was then utilized to redeem the special limited partnership interest and certain other existing limited partnership interests. For financial reporting purposes, this portion of the Partnership Recapitalization was accounted for as an equity transaction with no effect on the carrying value of the Partnership's assets. However, for tax purposes, even though the New Cash Partners assumed the redeemed limited partners' tax basis capital accounts, they will be entitled to additional outside tax basis reflecting the amount invested. In addition, the Partnership purchased certain net assets of DD Cable Partners, L.P. and DD Cable Holdings, Inc. ("DD Cable") through the net issuance of approximately $55.6 million in limited partnership interests. For financial reporting purposes, the acquisition was accounted for under the purchase method of accounting at fair market value. For tax purposes, the basis in the acquired net assets was recorded at DD Cable's historical tax basis. This results in a built-in gain on these assets based on the difference between the fair market value and tax basis of the assets at August 30, 1996. In connection with the Partnership Recapitalization, the general partnership interest of Triax Cable GP was converted to a non-managing general partnership interest. Triax Cable GP then contributed an additional $1.1 million to maintain its approximate 1% proportionate interest in the Partnership. Triax Midwest General Partner, L.P. ("Midwest GP" or the "Managing General Partner") was appointed the managing general partner. The general partner of Midwest GP is Triax Midwest, L.L.C., a wholly-owned subsidiary of Triax Telecommunications Company, L.L.C. ("TTC"). Midwest GP made no partnership equity contributions to the Partnership and received only a residual interest in the Partnership, as discussed below under "Allocations of Profits, Losses, Distributions and Credits Subsequent to Partnership Recapitalization". As provided for in the Partnership Agreement, as amended, certain of the New Cash Partners (the "Committed Partners") committed to fund additional monies totaling $50.0 million for future acquisitions of the Partnership through August 1999. In conjunction with the Partnership's Indiana and Illinois Acquisitions during 1997 and the Illinois acquisition of September 30, 1998 (Note 3), certain limited partners contributed approximately $13.0 million and $15.0 million, respectively. Of these total contributions, approximately $27.0 million was contributed by the Committed Partners, which reduced their total funding commitment to approximately $23.0 million. F-7

TRIAX MIDWEST ASSOCIATES, L.P. NOTES TO FINANCIAL STATEMENTS--(Continued) December 31, 1997 and 1998 and June 30, 1999 (All amounts related to the June 30, 1998 and 1999 periods are unaudited) During 1997, TTC and certain officers of TTC (the "Officers") purchased limited partner interests in Triax Investors Midwest, L.P. ("Investors Midwest"), which holds a limited partner interest in the Partnership. Subsequent to TTC's and the Officers' purchase of these Investors Midwest interests, Investors Midwest elected to distribute its interest in the Partnership to certain of its partners, resulting in TTC owning a direct limited partner interest in the Partnership. The Partnership Agreement, as amended, provides that on August 30, 2001 each limited partner has the option to sell its interest to the Partnership for fair market value at the time of the sale. The fair market value is to be determined by appraised value approved by a majority vote of the Advisory Committee. In accordance with the Partnership Agreement, if the Partnership is unable to finance the acquisition of such interests, such selling limited partners can cause the liquidation of the Partnership. Allocation of Profits, Losses, Distributions and Credits Subsequent to Partnership Recapitalization Distributions Cash distributions are to be made to both the limited partners and Triax Cable GP equal to their adjusted capital contributions, then to the limited partners and Triax Cable GP in an amount sufficient to yield a return of 13% per annum, compounded annually (the "Priority Return"), then varying rates of distribution to the Managing General Partner (17% to 20%) and to the limited partners and Triax Cable GP (83% to 80%) based on internal rates of return earned by the New Cash Partners, as set forth in the Amended and Restated Partnership Agreement, on their adjusted capital contributions. Losses from Operations The Partnership will allocate its losses to the limited partners and Triax Cable GP according to their proportionate interests in the book value of the Partnership, except losses will not be allocated to any limited partner which would cause the limited partner's capital account to become negative by an amount greater than an amount which the limited partners are obligated to contribute to the Partnership. Profits and Gains Generally, the Partnership will allocate its profits according to the limited partners' and Triax Cable GP's proportionate interests in the book value of the Partnership until profits allocated to limited partners equal losses previously allocated to them. A special allocation of gain equal to the difference between the fair value and tax basis of contributed property will be made, with respect to partners contributing property to the Partnership, upon the sale of the contributed Partnership assets. (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. F-8

TRIAX MIDWEST ASSOCIATES, L.P. NOTES TO FINANCIAL STATEMENTS--(Continued) December 31, 1997 and 1998 and June 30, 1999 (All amounts related to the June 30, 1998 and 1999 periods are unaudited) Revenue Recognition Revenues are recognized in the period the related services are provided to the subscribers. Income Taxes No provision has been made for federal, state or local income taxes because they are the responsibility of the individual partners. The principal difference between tax and financial reporting results from different depreciable tax basis in various assets acquired (Note 1). Property, Plant and Equipment Property, plant and equipment are stated at cost. Replacements, renewals and improvements are capitalized and costs for repairs and maintenance are charged directly to expense when incurred. The Partnership capitalized a portion of technician and installer salaries to property, plant and equipment, which amounted to $1,134,000 in 1996, $1,196,132 in 1997, $1,333,296 in 1998 and $601,889 and $590,351 for the six months ended June 30, 1998 and 1999, respectively.

SOP 98-5 broadly defines start-up activities and requires the costs of such start-up activities and organization costs to be expensed as incurred. SOP 98-5 is effective for fiscal years beginning after December 15, 1998 and the initial application is reported as a cumulative effect of a change in accounting principle. Effective January 1, 1999, the Partnership recognized a cumulative effect of an accounting change adjustment related to net deferred organization costs totaling approximately $660,000 as of December 31, 1998. Reclassifications Certain amounts in the accompanying financial statements have been reclassified to conform to the current year presentation. (3) ACQUISITIONS/SALES On August 30, 1996, the Partnership purchased certain cable television system assets, located in Illinois, Minnesota, Wisconsin and Iowa, from DD Cable, including the assumption of certain liabilities of the acquired business. The acquisition was financed by issuing net limited partnership interests valued at approximately $55.6 million.

A commitment fee is charged on the daily unused portion of the available commitment. This fee ranges from 1/4% to 3/8% per annum based on the Partnership's leverage ratio, as defined. The Revolving Credit Loan and each of the Term A, B, and C Loans are collateralized by all of the property, plant and equipment of the Partnership, as well as the rights under all present and future permits, licenses and franchises. On June 24, 1998, the Partnership completed a restructuring of the Revolving Credit Loan and the Term A, B and C Loans. Under the terms of the restructuring agreement, the total availability of this facility increased from $375 million to $475 million, in order to complete certain planned acquisitions (see Note 3) and to provide for future growth. The Partnership entered into LIBOR interest rate agreements with the lenders related to the Revolving Credit Loan and the Term A and Term B Loans. The Partnership fixed the interest rate for the Revolving Credit Loan on $71 million at 7.38% for the period from April 6, 1999 to July 6, 1999 and on $25 million at 7.38% for the period from April 26, 1999 to July 26, 1999. The Term A Loan and Term B Loans are fixed at 7.38% and 7.50%, respectively, for the period from April 26, 1999 to July 26, 1999. In addition, the Partnership has entered into various interest rate swap transactions covering $195 million in notional amount as of June 30, 1999, which fixes the weighted average three- month variable rate at 5.6%. These swap transactions expire at various dates through October 2000. The Term A Loan requires principal payments to be made quarterly, beginning in September 2000. The quarterly payments begin at $1,375,000 per quarter and increase each September 30th thereafter. The Term B and Term C Loans require total quarterly principal payments of $177,083 for the quarters ending September 2000 and December 2000. Quarterly principal payments totaling $88,542 are then required through December 31, 2005, at which time the quarterly payments increase to $3,187,500 through December 31, 2006 and $35,062,500 at March 31, 2007. The Loans are due in full on June 30, 2007. F-14

TRIAX MIDWEST ASSOCIATES, L.P. NOTES TO FINANCIAL STATEMENTS--(Continued) December 31, 1997 and 1998 and June 30, 1999 (All amounts related to the June 30, 1998 and 1999 periods are unaudited) The loan agreements contain various covenants, the most restrictive of which relate to maintenance of certain debt coverage ratios, meeting cash flow goals and limitations on indebtedness. Debt maturities required on all debt as of December 31, 1998 are as follows (amounts in thousands): Year Amount ---- -------- 1999.............................................................. $ 775 2000.............................................................. 3,861 2001.............................................................. 16,375 2002.............................................................. 31,417 2003.............................................................. 39,407 Thereafter........................................................ 312,583 -------- $404,418 ======== (5) RELATED PARTY TRANSACTIONS During the eight month period ending August 31, 1996, TTC provided management services to the Partnership for a fee equal to 5% of gross revenues, as defined. Charges for such management services amounted to approximately $1,567,000. TTC also allocated certain overhead expenses to the Partnership which primarily relate to employment costs. These overhead expenses amounted to approximately $371,000 for the eight months ended August 31, 1996. Commencing August 30, 1996, the Partnership entered into an agreement with TTC to provide management services to the Partnership for a fee equal to 4% of gross revenues, as defined. The agreement also states the Partnership will only be required to pay a maximum fixed monthly payment of $275,000, which can be adjusted for any acquisitions or dispositions by the Partnership at a rate of $.8333 per acquired/disposed subscriber. Charges for such management services provided by TTC amounted to approximately $1,100,000, $3,573,000 and $4,048,000 in 1996, 1997 and 1998, respectively, and $1,933,000 and $2,218,000 for the six months ended June 30, 1998 and 1999, respectively. The remainder of the management fees earned but unpaid will be distributable to TTC only after Triax Cable GP and the limited partners have been distributed their original capital investments and then the deferred and unpaid portion of the management fee will be paid pari passu with the first 7.5% of the Priority Return, as defined. The earned but unpaid fees totaled approximately $62,000, $488,000 and $738,000 in 1996, 1997 and 1998, respectively, and $353,000 and $422,000 for the six months ended June 30, 1998 and 1999, respectively. The cumulative unpaid fees totaled approximately $62,000, $550,000, $1,288,000 and $1,760,000 as of December 31, 1996, 1997, 1998 and June 30, 1999, respectively. These amounts have been reflected in the statement of partners' deficit as "accumulated residual equity interest of TTC", which has been allocated to the non-managing General Partner. Commencing August 30, 1996, the Partnership entered into a programming agreement with InterMedia Capital Management II, L.P. ("InterMedia"), an affiliate of DD Cable, to purchase programming at InterMedia's cost, which includes volume discounts InterMedia might earn. Included in this agreement is a provision that requires the Partnership to remit to InterMedia an administrative fee, based on a calculation stipulated in the agreement, which amounted to approximately $444,000, $1,482,000 and $1,826,000 in 1996, 1997 and 1998, respectively, and $843,000 and $1,040,000 for the six months ended June 30, 1998 and 1999, respectively.

NOTES TO FINANCIAL STATEMENTS--(Continued) December 31, 1997 and 1998 and June 30, 1999 (All amounts related to the June 30, 1998 and 1999 periods are unaudited) (6) LEASES The Partnership leases office facilities, headend sites and other equipment under noncancelable operating lease agreements, some of which contain renewal options. Total rent expense, including month-to-month rental arrangements, was approximately $364,000, $583,000 and $737,000 in 1996, 1997 and 1998, respectively, and $336,000 and $413,000 for the six months ended June 30, 1998 and 1999, respectively. Pole attachment fees totaled approximately $496,000, $798,000 and $970,000 in 1996, 1997 and 1998, respectively, and $473,000 and $538,000 for the six months ended June 30, 1998 and 1999, respectively. Future minimum rental commitments under noncancelable operating leases subsequent to December 31, 1998 are as follows (amounts in thousands): Year Amount ---- ------ 1999................................................................ $685 2000................................................................ $511 2001................................................................ $377 2002................................................................ $298 2003................................................................ $238 Thereafter.......................................................... $757 (7) FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying amounts of cash and cash equivalents approximates fair value because of the nature of the investments and the length of maturity of the investments. The estimated fair value of the Partnership's debt instruments are based on borrowing rates that would be substantially equivalent to existing rates, therefore, there is no material difference in the fair market value and the current value. (8) REGULATORY MATTERS In October 1992, Congress enacted the Cable Television Consumer and Competition Act of 1992 (the "1992 Cable Act") which greatly expanded federal and local regulation of the cable television industry. In April 1993, the Federal Communications Commission ("FCC") adopted comprehensive regulations, effective September 1, 1993, governing rates charged to subscribers for basic cable and cable programming services (other than programming offered on a per-channel or per-program basis). The FCC implemented regulation, which allowed cable operators to justify regulated rates in excess of the FCC benchmarks through cost of service showings at both the franchising authority level for basic service and to the FCC in response to complaints on rates for cable programming services. On February 22, 1994, the FCC issued further regulations which modified the FCC's previous benchmark approach, adopted interim rules to govern cost of service proceedings initiated by cable operators, and lifted the stay of rate regulations for small cable systems, which were defined as all systems serving 1,000 or fewer subscribers. On November 10, 1994, the FCC adopted "going forward" rules that provided cable operators with the ability to offer new product tiers priced as operators elect, provided certain limited conditions are met, permit cable operators to add new channels at reasonable prices to existing cable programming service tiers, and created an additional option pursuant to which small cable operators may add channels to cable programming service tiers. F-16

TRIAX MIDWEST ASSOCIATES, L.P. NOTES TO FINANCIAL STATEMENTS--(Continued) December 31, 1997 and 1998 and June 30, 1999 (All amounts related to the June 30, 1998 and 1999 periods are unaudited) In May 1995, the FCC adopted small company rules that provided small systems regulatory relief by implementing an abbreviated cost of service rate calculation method. Using this methodology, for small systems seeking to establish rates no higher than $1.24 per channel, the rates are deemed to be reasonable. In February 1996, the Telecommunications Act of 1996 ("1996 Act") was enacted which, among other things, deregulated cable rates for small systems on their programming tiers. Federal law is expected to eliminate the regulation of rates for non-basic cable programming service tiers after March 31, 1999. Management of the Partnership believes they have complied in all material respects with the provisions of the 1992 Cable Act and the 1996 Act, including rate setting provisions. To date, the FCC's regulations have not had a material adverse effect on the Partnership due to the lack of certifications by the local franchising authorities. Several rate complaints have been filed against the Partnership with the FCC. However, management does not believe this matter will have a material adverse impact on the Partnership. (9) COMMITMENTS AND CONTINGENCIES The Partnership has been named as a defendant in a class action lawsuit in the state of Illinois, challenging the Partnership's policy for charging late payment fees when customers fail to pay for subscriber services in a timely manner. The Partnership is currently in settlement negotiations with the plaintiffs and expects the litigation to be settled by the end of the year. However, management does not believe the ultimate outcome of this matter will have a material adverse effect on its financial condition. (10) EVENTS SUBSEQUENT TO DATE OF AUDITOR'S REPORT (UNAUDITED) On April 29, 1999, the Partnership entered into a definitive agreement to sell its cable television system assets to Mediacom LLC for $740 million, subject to adjustment for subscriber benchmarks and other pro-rations in the normal course. The sale is expected to occur in the fourth quarter of 1999 subject to regulatory and other customary approvals. On July 31, 1999, the Partnership acquired certain cable television system assets, located in Illinois, including certain liabilities of the acquired business, from an unrelated third party. The purchase price of approximately $4.0 million was accounted for by the purchase method of accounting. Effective September 30, 1999, the Partnership acquired certain cable television system assets, located in Illinois, including certain liabilities of the acquired business, from an unrelated third party. The purchase price of $1.1 million was accounted for by the purchase method of accounting. In September 1999, the Partnership's independent billing company notified the Partnership of its intent to assess additional charges should the Partnership terminate the existing contract between the parties prior to the contractual termination date of June 24, 2004. Mediacom LLC intends to change the billing service provider for subscribers obtained in connection with its asset purchase from the Partnership. The Partnership intends to vigorously defend against any claims by the billing company, and believes the ultimate resolution of this matter will not have a material adverse impact on its financial position or results of operations.
