Section II Situation Analysis

Summary After an intense period of expansion following the deregulatory 1996 Telecom Act and the increased demand derived from the initial growth of the Internet, the telecommunications industry is undergoing a significant contraction. During the 1990s, driven by the advent of wireless and the Internet, telecom industry revenues grew at a 10% CAGR, more than twice its historical rate. Excluding the impact of bankruptcies, telecom industry revenues shrank 3% in 2002. U.S. Wireline annual capital expenditures grew three-fold to over $100 billion in 2000. Spending declined 20% in 2001, and 53% in 2002. Outlook for 2003 calls for an additional 10% retraction. Valuations for every communications related concern have retracted significantly. The NASDAQ Telecom Index is down 90% over the last three years versus declines of 70%, 40% and 23% for the NASDAQ Composite S&P500 and DOW30 respectively. TELECOM FUNDAMENTALS

Performance The NASDAQ Telecom Index is down 90% over the last three years versus declines of 70%, 40% and 23% for the NASDAQ Composite S&P500 and DOW30 respectively. The sell off is largely broad based with little variation from long distance providers, wireless carriers, to equipment vendors. Even the larger more stable regional bell operating companies (VZ, BLS, SBC, Q) are suffering, with earnings down 40%. TELECOM FUNDAMENTALS

Wireline Communications TELECOM FUNDAMENTALS 2002 US Wireline CAPx came in 55% below 2001, the outlook for 2003 does not look promising. Between 1996 and 2001, fiber miles deployed by all carriers doubled, in 2002 more fiber went dark then was lit. The bankruptcy filings by WorldCom, Global Crossing and others, coupled with high debt loads at other major carriers has sent the entire sector into a nosedive. Competitive entry following the 1996 Telecom Act has reversed. Mergers and to a larger degree bankruptcy filings has driven the number of public telcos from 48 in 1999 to 20 in 2002. 1996 1997 1998 1999 2000 2001 2002E Total US 37881 44735 54306 77387 102835 81836 38187 Y/Y Change 0.22 0.18 0.21 0.43 0.33 -0.2 -0.53 1995 1996 1997 1998 1999 2000 2001 2002 Total US 21 27 31 35 48 43 26 20

ILECs TELECOM FUNDAMENTALS After growing revenues at 5% CAGR between 1996 and 2001, revenues at the incumbent local exchange carriers (ILECs) declined 3% in 2002, despite a reduction in competition and their expansion into long distance markets . Through a combination of customer spending reductions and competition, largely from resellers, ILEC phone lines in service are shrinking at a 3% annualized rate. Responding to competition, ILECs increased capital spending to $32 billion in 2000, representing 20% of revenues. In 2002, CAPx fell 38% to $18 billion or 11% of revenues - in line with historical averages. 1996 1997 1998 1999 2000 2001 2002 Total US 16471 20501 21514 26417 32158 30082 18661 Y/Y Change 0.05 0.24 0.05 0.23 0.22 -0.06 -0.38 1Q01 2Q01 3Q01 4Q01 1Q02 2Q02 3Q02 4Q02 Lines 199 198.4648 198.1672 197.8804 197.26 196.3084 195.1552 194.1552 Y/Y -0.003 -0.005 -0.007 -0.008 -0.009 -0.011 -0.015 -0.019

IXCs TELECOM FUNDAMENTALS Heading into the Internet boom, long distance competitors, or interexchange carriers (IXCs) deployed over $200 billion in capital to lay some 60,000 route miles of new fiber. Following initial deregulation and entry of the first LD competitors (MCI et al.) LD prices plummeted. As the industry consolidated and demand ramped, prices recovered briefly before the entry of next-wave fiber competitors. The convergence of oversupply, contraction in demand and price erosion, led to the Chapter 11 filings of 360, Worldcom, Global Crossing, and Williams. Remaining players remain over-levered with respect to earnings prospects. 1996 1997 1998 1999 2000 2001 2002 Total US 19893 21381 27441 42225 57222 44220 16309 Y/Y Change 0.29 0.07 0.28 0.54 0.36 -0.23 -0.63 Interstate 1984 100 1985 97 1986 87.3 1987 76.9986 1988 75.3816294 1989 74.1001417 1990 74.02604156 1991 73.06370302 1992 73.79434005 1993 76.59852497 1994 81.27103499 1995 81.35230603 1996 81.92177217 1997 88.3116704 1998 87.95842372 1999 89.98146746 2000 86.11226436 2001 79.22328321 2002 75.26211905

CLECs From 1996, the year of the Telecommunications Act, to 2001, competitive local exchange carriers (CLECs) deployed $40 billion in capital expenditures. During that period CLECs raised over $50 billion in debt & Equity. At the end of 2000 34 CLECs were listed on the NASDAQ national market. CLEC revenues, which included local, long-distance, and data services grew to $12 billion in 2001, representing 5% of the total US Telecom services market. In 2001 and 2002 the majority of CLECs restructured or went out of business. Surviving entities have eliminated expansion, and have closed numerous networks. 1996 1997 1998 1999 2000 2001 2002E Total US 1024 1998 3811 6788 11394 5809 1718 Y/Y Change 1.23 0.95 0.91 0.78 0.68 -0.49 -0.7 1996 1997 1998 1999 2000 2001 2002E Revenue 2 3 5.5 8 10.4 12.3 5.08 Share 0.01 0.02 0.03 0.03 0.04 0.05 0.018 TELECOM FUNDAMENTALS

Information Technology Technology Fundamentals Market research firm IDC recently lowered its IT forecast for 2003 to 3.7% and lowered long-term growth expectations to 6.5% - 7% from its previous target of 8% to 9%. According to the monthly CIO Magazine survey, the IT spending outlook took a jump this year with firms reporting a 4.4% increase over the last 12 months - the first positive indicator since May 2002. Not surprisingly, network security remains a top concern for IT managers, with 53% of managers looking to spend more in that area.

Customer Concentration With 56% of revenues derived from the telecom sector, Lexent's business is highly correlated to the downturn in that market. Lexent's corporate business, 29% of revenues, is also highly correlated with the IT spending slowdown. Top 5 customer accounted for 57% of revenues. The company's two largest customers are both telecoms and are both under financial pressure.

Lexent Business Conditions Fiber Networks Lexent's plan to build and operate a fiber ring in New York will likely meet stiff competition and very narrow margins. In addition to incumbent provider Verizon, seven competitors have already built fiber rings in New York.

Discounted Cash Flow Lexent's annual free cash flow was estimated for 2003- 2007 based on projections developed by Rodman with the Company's assistance. Terminal value in 2007 was calculated by applying a 6.0 multiple to 2007 EBITDA less the balance of the restructuring reserve and long-term incentive compensation. Rodman applied discount rates between 15% and 25%. The implied price is largely driven by Lexent's current cash position

Conclusion Based on the foregoing analysis, it is our conclusion that the transaction price of $1.50 per share in cash is fair, from a financial point of view to the stockholders of Lexent (other than the Management Group).
