                    METROMEDIA FIBER NETWORK, INC. & SUBSIDIARIES
                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)


 1.  BASIS OF PRESENTATION
    
    The consolidated financial statements in this filing under Form 10-Q have
    been prepared in accordance with the United States Securities and Exchange
    Commission Regulation S-X and consequently do not include all disclosures
    required under generally accepted accounting principles.  The interim
    unaudited financial statements should be read in conjunction with the
    audited Consolidated Financial Statements and accompanying Notes of
    Metromedia Fiber Network, Inc. & Subsidiaries (the "Company") for the year
    ended December 31, 1996 contained in the Company's Form S-1, effective
    October 28, 1997.  The Form S-1 includes information with respect to the
    Company's significant accounting and financial reporting policies and other
    pertinent information. The Company believes that all adjustments of a
    normal recurring nature that are necessary for a fair presentation of the
    results of the interim periods presented in this filing have been made.  On
    April 29, 1997, the Company effected a 3 for one stock split of the
    outstanding shares of its common stock.  On September 24, 1997, the Company
    effected a .507 for one reverse stock split of the outstanding shares of
    its common stock.  The financial statements give retroactive effect to
    these stock splits.  The results of operations for interim periods are not
    necessarily indicative of the results of operations for the full year.
    Certain balances have been reclassified to conform to the current period
    presentation.  

2.  ACTIVITIES DURING THE PERIOD

    A.  NAME CHANGE
    On August 14, 1997, the name of the corporation was formally changed from
    National Fiber Network, Inc. to Metromedia Fiber Network, Inc. 
    
    B.  METROMEDIA INVESTMENT 
    On April 30, 1997, the Company sold an aggregate of 8,403.325 shares of
    Series B convertible preferred stock, par value $0.01 per share (the
    "Series B preferred stock"), to Metromedia Company and affiliates
    ("Metromedia") for an aggregate purchase price of $32.5 million (the
    "Metromedia Investment").  Each share of the Series B preferred stock was
    convertible into 507 shares of the Company's common stock.
    
    A portion of the proceeds from the Metromedia Investment was used to repay
    the Metromedia Loan, discussed below, and accrued interest thereon
    ($4,058,127), repay other short-term indebtedness ($3,485,000), and redeem
    (for $2,115,000) all outstanding shares of the Company's preferred stock
    (the "Series A preferred stock") and related warrants. 
    
    Through April 30, 1997, Metromedia loaned the Company an aggregate of
    $4,000,000 (the "Metromedia Loan").  A portion of the proceeds from the
    Metromedia Loan was used to fund an escrow account to repurchase, on behalf
    of the Company, 588,470 shares of common stock of the Company and warrants
    to purchase 207,883 shares of its common stock.  Pursuant to the escrow
    arrangement, such securities were pledged to Metromedia as security for the
    Metromedia Loan. Upon repayment of the Metromedia Loan, the purchased
    shares were released from escrow and delivered to the Company.

7.  NOTES PAYABLE
    
    A.  On April 18, 1995, the Company entered into a loan agreement with AT&T
    Wireless for $500,000, bearing interest at 11% per annum, originally due
    120 days from the date of the loan.  Pursuant to a supplemental agreement
    dated January 12, 1996, the parties agreed to extend the maturity date of
    this loan to November 18, 1996.  Pursuant to a second supplemental
    agreement dated March 1997, the parties agreed to extend the maturity date
    of the loan to June 30, 1997.  In July 1997, the note along with all
    accrued interest was paid in full. 

    On February 16, 1995, the Company issued to the above party a warrant
    entitling the holder to purchase a total of 669,167 shares of the Company's
    common stock.  This warrant was canceled and replaced by a new warrant
    issued on February 13, 1997 for 456,300 of shares of its common stock, with
    an exercise price of $4.85 per share.  The new warrant expires on February
    13, 2000.
    
    B.  On September 24, 1996, the Company entered into a loan agreement with
    Sterling Capital (the "Sterling Loan") for $550,000.   The loan bore
    interest at 10% per annum with an original maturity date of March 1, 1997. 
    The loan was secured by all of the Company assets and subordinated to a
    loan to U.S. One, discussed below.  As an incentive for the Sterling Loan,
    the Company issued to Sterling warrants to purchase 94,302 shares of common
    stock of the Company.  The warrants can be exercised on the later of (i)
    the third anniversary of the Sterling Loan or (ii) twelve months after the
    Company has completed an initial public offering.  On May 1, 1997, the loan
    along with all accrued interest was paid in full with a portion of the
    proceeds from the Metromedia Investment.
    
    C.   On April 16, 1996, the Company entered into an agreement with U.S. One
    Communications ("U.S. One") providing for exclusive usage rights for 8 to
    12 fibers of the Company's fiber optic transmission network. The initial
    term of the agreement was for a period beginning April 1996 and expiring
    December 2008.  The agreement was renewable, at the option of U.S. One, for
    an extended term of 13 years, expiring December 2021.  Concurrent with the

7.  NOTES PAYABLE (CONTINUED)

    usage rights for fiber, the Company and U.S. One entered into a bridge
    financing agreement (the "U.S. One Bridge Loan").
    
    On April 30, 1997, the Company and U.S. One amended the above agreement for
    exclusive usage rights for fiber (the "Amended Lease Agreement") to permit
    U.S. One the exclusive right to use 888 fiber miles of the Company's fiber
    optic network.  Additionally, pursuant to the Amended Lease Agreement, U.S.
    One received an option to acquire access from the Company of up to 1,620
    additional fiber miles upon payment of a predetermined amount. In
    accordance with the amended agreement, the following transactions occurred: 
    (i) all accrued interest from the inception of the U.S. One Bridge Loan was
    waived by U.S. One,  (ii) the $4,900,000 principal balance of the U.S. One
    Bridge Loan was offset against $3,530,000 in a scheduled payment due from
    U.S. One to the Company under the Amended Lease Agreement, and (iii) the
    Company paid to U.S. One the difference of $1,370,000 on April 30, 1997
    with a portion of the proceeds of the Metromedia Investment.
    
    In connection with the execution of the aforementioned agreements for
    exclusive usage rights for fiber and the U.S. One Bridge Loan, the Company
    entered into a letter agreement with U.S. One providing for the sale of a
    warrant to purchase common stock of the Company, subject to U.S. One
    exercising its option under the Amended Lease Agreement for additional
    fiber by a certain date.  Under this arrangement, the warrant, if delivered
    to U.S. One, is exercisable for a number of shares to be determined at the
    Company's discretion, subject to a minimum number of 76,050 shares and a
    maximum number of 456,300 shares.  The per share exercise price is to be
    determined pursuant to a formula, but in no event shall the aggregate
    purchase price exceed $1,250,000.
    
    On July 24, 1997, U.S. One filed for protection as a debtor-in-possession

9.  RELATED PARTY TRANSACTIONS

    In 1997, the Company paid in full the outstanding balance of a loan made to
    the Company in prior years by the Company's majority shareholder.

10. DEFERRED REVENUE

    The Company's revenues are primarily derived from the lease of dark fiber
    optic cable.  Lease payments are structured as either prepayments or
    monthly recurring charges.  Prepayments are accounted for as deferred
    revenue and recognized over the term of the respective customer lease
    agreement.  For nine months ended September 30, 1997, the Company has
    received prepaid lease payments totaling $9 million.

    share and expire ten years after date of grant.  The Company has recorded a
    non-cash charge of $19,124,453 to reflect the value of such grants.

13. COMMITMENTS AND CONTINGENCIES   

    A.  In February 1997, a former investment advisor to the Company asserted a
    claim against the Company in the amount of $305,731 pursuant to an
    agreement made on June 27, 1995, for the payment of certain fees and
    expenses.  In September 1997, the Company paid the former investment
    advisor  $250,000 in full settlement of such claim plus any and all related
    expenses.

    B. On or about April 18, 1997, Howard Katz, Realprop Capital Corporation
    and Evelyn Katz commenced an action against, among others, the Company,
    Stephen A. Garofalo, Peter Sahagen and Peter Silverman in the United States
    District Court for the Southern District Court of New York captioned KATZ,
    ET AL. V. NATIONAL FIBER NETWORK, INC., ET AL., No. 97 Civ. 2764 (JGK) (the
    "Katz Litigation").  On May 28, 1997, the plaintiffs filed an amended
    complaint and on September 15,

13. COMMITMENT AND CONTINGENCIES (CONTINUED)
    
    1997, the plaintiffs filed a second amended complaint.  The complaint as
    amended alleges causes of action for, among other things, common law fraud,
    violations of Section 10(b) of the Securities Exchange Act of 1934 and Rule
    10b-5 promulgated thereunder, breach of fiduciary duty and negligent
    misrepresentation for alleged misrepresentations and omissions made in
    connection with the repurchase of a right to purchase an aggregate of
    264,631 shares of Class A common stock of the Company, which class of
    shares was authorized in October 1997, as more fully described below under
    the footnote entitled, "Initial Public Offering", and an option to purchase
    warrants for the purchase of 207,888 shares of Class A common stock.  The
    amended complaint also contains allegations of corporate waste against the
    Company and Stephen A. Garofalo.  Plaintiffs seek, among other things,
    compensatory damages of not less than $12 million, punitive damages in the
    amount of $100 million and, in the alternative, rescission of the purchase
    of the common stock and warrants by the Company.  On June 11, 1997, various
    defendants, including the Company and Stephen A. Garofalo moved to dismiss
    the amended complaint.  The Company intends to vigorously defend itself
    against these allegations based on its belief that the Company acted
    appropriately in connection with the matters at issue in this litigation. 
    No assurance can be made, though, that the Company will not determine that
    the advantages of entering into a settlement outweigh the risk and expense
    of protracted litigation or that ultimately the Company will be successful
    in its defense of the allegations.  If the Company is unsuccessful in its
    defense of the allegations, an award of the magnitude being sought by the
    plaintiffs in the Katz Litigation would have a material adverse effect on
    the Company's financial condition or results of operations. 
    
    C.  On or about October 20, 1997, Vento & Company of New York, LLC ("VCNY")
    commenced an action against the Company, Stephen A. Garofalo, Peter
    Silverman, the law firm of Silverman, Collura, Chernis & Balzano, P.C.,
    Peter Sahagen, Sahagen Consulting Group of Florida (collectively, the
    "Sahagen Defendants") and Robert Kramer, Birdie Capital Corp, Lawrence
    Black, Sterling Capital LLC, Penrush Limited, Needham Capital Group, Arthur
    Asch, Michael Asch and Ronald Kuzon (the "Kramer Defendants") in the United
    States District Court for the Southern District of New York (No. 97 CIV
    7751) (the "VCNY Litigation").  The complaint alleges causes of action for,
    among other things, violation of Section 10(b) of the Securities Exchange
    Act of 1934 and Rule 10b-5 promulgated thereunder, fraud and fraudulent
    concealment, breach of fiduciary duty and negligent misrepresentation and
    omission made in connection with respect to the sale by VCNY of 1,368,900
    shares of Class A common stock to Peter Sahagen and the Kramer Defendants
    on January 13, 1997 (the "VCNY Sale").  The complaint also alleges a cause
    of action for declaratory judgement asserting that certain "piggyback"
    registration rights are applicable to shares of the Company's Class A
    common stock which VCNY owns (or which may be rescinded to VCNY pursuant to
    its requested remedies).  The complaint further requests a declaratory
    judgement that a stockholders' agreement between the Company, Stephen A.
    Garofalo and VCNY be declared operative, which agreement indirectly
    required VCNY, through designated directors, to approve significant
    transactions, and, accordingly, the Metromedia Loan and the Metromedia
    Investment should be rescinded and Mr. Vento should be reappointed as Chief
    Executive Officer of the  Company.  The Company believes, among other
    things, that the stockholder's agreement to which Mr. Vento was a party had
    terminated and, as a result, Mr. Vento had no such rights to approve the
    Metromedia Investment or the Metromedia Loan or to remain as Chief
    Executive Officer of the Company. Plaintiff seeks, among other things, (i)
    rescission of the VCNY Sale, or alternatively, damages in an amount not
    presently ascertainable, but believed to be in the excess of $36 million,
    together with interest thereon, (ii) punitive damages in the amount of $50
    million, and (iii) the declaratory judgements discussed above.  The Company
    intends to vigorously defend itself against

    these allegations based on its belief that it acted appropriately in
    connection with the matters at issue in this litigation.  However, no
    assurance can be made that the Company will not determine that the
    advantages of entering into a settlement outweigh the risk and expense of
    protracted litigation or that ultimately the Company will be successful in
    its defense of the allegations. If the Company is unsuccessful in its
    defense of the allegations, an award of the magnitude being sought by the
    plaintiffs in the VCNY Litigation would have a material adverse effect on
    the Company's financial condition or results of operations.

14. INITIAL PUBLIC OFFERING
    
    A.  On November 3, 1997, the Company completed the initial public offering
    (the "IPO") of 9,108,000 shares of its Class A common stock, par value
    $0.01 per share, at an offering price of $16 per share.  The net proceeds
    to the Company from the IPO, before deducting expenses of the IPO, were
    approximately  $135.5 million.

    B.   On October 28, 1997, the total authorized number of shares of common
    stock of the Company was increased to 200 million shares, par value $0.01
    per share, of which 180 million shares were designated Class A common stock
    and 20 million shares were designated Class B common stock. 
    
    In addition, on October 28, 1997, a total of 9,564,940 shares of the common
    stock of the Company, par value $0.01 per share, owned by stockholders
    prior to the IPO, were exchanged for an equal number of shares of Class A
    common stock.  Also, 8,403.325 shares of the Company's Series B convertible
    preferred stock, owned by stockholders prior to the IPO, were exchanged for
    4,260,486 shares of Class B common stock, par value $0.01 per share.  The
    Company also reserved for issuance 4,260,486 shares of Class A common stock
    for conversion of the Class B common stock and 1,000,000 shares of Class A
    common stock for future issuances pursuant to the Company's 1997 Incentive
    Stock Plan, also adopted on October 28, 1997, by a majority of the
    shareholders of record as of that date.  Further, on October 28, 1997, a
    total of 39,327 shares of Class B common stock outstanding were converted
    into an equivalent number of shares of Class A common stock.  
    
    As of October 28, 1997, no shares of the Company's Series A preferred stock
    remained outstanding.  In addition, immediately following the issuance of
    the Class B common shares in exchange for all of the Company's outstanding 
    Series B preferred stock, there were no shares of the Company's Series B
    preferred stock.  On November 7, 1997, both the Series A and Series B
    preferred stock of the Company were eliminated pursuant to actions by the
    Board of Directors.

15. SUBSEQUENT EVENT 

    On November 26, 1997, the Company entered into a joint venture with Racal
    Telecommunications, Inc. ("Racal") to form MFNRAC, L.L.C. (The "Joint
    Venture").  The Joint Venture will enable the Company and Racal to provide
    broadband transatlantic communication services to their respective
    customers. The Company anticipates that initial service through the Joint
    Venture, which will include fiber optic international leased lines, ranging
    in capacity from 2Mb to 45Mb, will be available by April 1998. Racal is
    part of the Racal Electronics Group which is headquartered in the United
    Kingdom, and is one of Europe's leading telecommunication providers of
    managed networks and support services.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

STATEMENT ON FORWARD-LOOKING INFORMATION
The following discussion of the financial condition and results of operations of
the Company should be read in conjunction with the consolidated financial
statements and related notes.  The following discussion contains certain
forward-looking statements that involve risks and uncertainties.  Factors that
could cause or contribute to such risks and uncertainties include, but are not
limited to, general economic and business conditions, competition, changes in
methods of marketing and technology and various other factors beyond the
Company's control.

RESULTS OF OPERATIONS
The Company is a facilities-based provider of technologically advanced,
high-bandwidth, fiber optic communications infrastructure to carrier and
corporate/government customers. The Company currently operates a 62 route fiber
optic mile network within the New York/New Jersey metropolitan area which
consists of 12,418 fiber miles. The Company plans to expand its existing network
within the next two years to encompass approximately 229,000 fiber miles, or 643
route miles, concentrated in the northeastern United States.  The planned
build-out will include intra-city fiber optic networks in Washington, D.C.,
Chicago and Philadelphia, as well as an inter-city network between New York City
and Washington, D.C.  The Company also intends to expand its network to link New
York City with London, England, thereby providing a valuable connection between
two of the world's most important financial centers. 

REVENUES
Revenues for the third quarter of 1997 were $1,202,621, or 1,093% greater than
revenues of $100,809 for the third quarter of 1996.  For the nine months ended
September 30, 1997, the Company recorded revenues of $1,744,507, which were 854%
higher than revenues of $182,844 for the nine months ended September 30, 1996. 
The increase in revenue for the three and nine months ended September 30, 1997
versus the three and nine months ended September 30, 1996 reflect higher one
time revenues associated with commencement of service to customers, as well as
an increase in the total number of customers served.

COST OF SALES 
Cost of sales were $1,310,207 in the third quarter of 1997, a 467% increase over
cost of sales of $230,879 for the third quarter of 1996.  For the nine months
ended September 30, 1997, cost of sales were $2,647,155, versus $665,880 for the
nine months ended September 30, 1996, an increase of 298%.  Cost of sales
increased for the three and nine months ended September 30, 1997 as compared to
1996 due to costs associated with the commencement of service to customers, as
well as higher fixed costs associated with the build-out of the Company's
network. Cost of sales as percentages of revenue for the third quarters of 1997
and 1996 were 109% and 229%, respectively.   For the nine months ended September
30, 1997 and September 30, 1996, cost of sales as percentages of revenue were
152% and 364%, respectively.  Management anticipates revenue will increase more
rapidly than fixed costs and, accordingly, expects that cost of sales as a
percentage of revenue will continue to improve.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS (CONTINUED)

SELLING, GENERAL AND ADMINISTRATIVE 
Selling, general and administrative expenses increased to $1,791,073 during the
third quarter of 1997, from $610,069 during the third quarter of 1996, an
increase of $1,181,004, or 194%. Selling, general and administrative expenses
for the nine months ended September 30, 1997 totaled $3,722,093, which was
$2,005,144, or 117%, higher than the $1,716,949 recorded for the nine months
ended September 30, 1996. The increase in selling, general and administrative
expenses for the three and nine months ended September 30, 1997 versus the three
and nine months ended September 30, 1996 resulted primarily from increased
overhead to accommodate the Company's anticipated growth. 

CONSULTING AND EMPLOYMENT INCENTIVES
Consulting and employment incentives expenses for the three and nine months
ended September 30, 1997 were $5,704,553 and $19,124,453, respectively, compared
with $3,651,442 for the nine months ended September 30, 1996.  There were no
such expenses for the three months ended September 30, 1996.  Consulting and
employment incentives expense incurred in 1997 reflects the value of stock
options issued to key employees, officers and directors in order to attract or
retain their services. For the nine months ended September 30, 1996, the amount
recorded reflects the expense associated with issuance of stock and warrants to
consultants in consideration for services rendered.

DEPRECIATION AND AMORTIZATION 
Depreciation and amortization expense of $193,748 was recorded during the three
months ended September 30, 1997, versus $148,814 during the three months ended
September 30, 1996, an increase of $44,934, or 30%.  For the nine months ended
September 30, 1997, depreciation and amortization expense was $566,683, versus
$441,133 for the nine months ended September 30, 1996, an increase of $125,550,
or 28%.  The increases in depreciation and amortization expense resulted from
increased investment in the Company's fiber optic network. 

INTEREST INCOME
Interest income was $287,159 and $491,334 during the three months ended
September 30, 1997 and the nine months ended September 30, 1997, respectively,
versus no interest income during the comparable 1996 periods.  Interest income
during 1997 was derived from investment of the Company's excess cash. In 1996,
the Company had no excess cash to invest and, accordingly, earned no interest
income.

INTEREST EXPENSE (INCLUDING FINANCING COSTS)
Interest expense (including financing costs) decreased in the three months ended
September 30, 1997 to $52,597, versus $1,312,208 for the three months ended
September 30, 1996.   For the nine months ended September 30, 1997 and 1996,
interest expense was $732,024 and $3,120,164, respectively. The decrease in
interest expense reflects the repayment of all of the Company's debt during the
nine months ended September 30, 1997 with the proceeds of the Metromedia
Investment, as well as lower financing costs.
 
NET LOSS
A net loss of $7,562,398 was recorded for the three months ended September 30,
1997, versus a net loss of $2,201,161 for the comparable period of 1996. For the
three months ended September 30, 1997 and 1996, the net loss per share was $0.61
and $0.17, respectively.  For the nine months ended September 30,

                                          12

<PAGE>


                    METROMEDIA FIBER NETWORK, INC. & SUBSIDIARIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS (CONTINUED)

1997 and 1996, the net loss was $24,556,567 and $9,412,724, respectively, or a
net loss per share of $1.96 and $0.82.  The increase in net losses was primarily
attributable to costs associated with organizing to meet the growth objectives
of the Company.  In particular, such costs include consulting and employment
incentives to attract and retain key employees, officers and directors, as well
as increased overhead to meet the Company's growth objectives. 
                                           
LIQUIDITY AND CAPITAL RESOURCES
On November 3, 1997, the Company raised $135.5 million in an initial public
offering of its common stock, before deducting estimated expenses of $1,000,000.
The Company anticipates spending approximately $140.0 million through 1998 on
the build-out of its network.  Management believes that the proceeds of the IPO,
plus cash on hand as of September 30, 1997 of $16,745,336, and cash generated
internally within the next fifteen months (including advance customer payments),
will be sufficient to fund the Company's planned build-out of its fiber optic
network and its other working capital needs through the year ended December 31,
1998.  The Company may also consider from time-to-time the private or public
sale of additional equity or debt securities of the Company, depending upon
market conditions.

For the nine months ended September 30, 1997, the Company's operating activities
required $3,868,344 of cash, versus an operating cash requirement of $2,725,200
during the comparable period of 1996. The increased cash requirement was
primarily due to the reduction of outstanding payables which originated during
1996, as well as increased prepaid and operating expenses.  For the nine months
ended September 30, 1997, operating cash requirements were in part funded by
$8,225,358 of advance payments received from customers. During the nine months
ended September 30, 1997, $1,747,644 of cash was utilized for investing
activities, $1,522,292 was expended on the build-out of the Company's network,
and $225,352 was expended on purchases of equipment. Cash flow from financing
activities during the nine months ended September 30, 1997 provided $21,897,000.
The Metromedia Investment of $32,500,000 on April 30, 1997 was utilized to repay
all the outstanding debt of the Company and to purchase all of the Company's
Series A preferred stock outstanding at April 30, 1997.

PART II  OTHER INFORMATION 

ITEM 1.  LEGAL PROCEEDINGS

a)  In February 1997, a former investment advisor to the Company asserted a
    claim against the Company in the amount of $305,731 pursuant to an
    agreement made on June 27, 1995, for the payment of certain fees and
    expenses.  In September 1997, the Company paid the former investment
    advisor  $250,000 in full settlement of such claim plus any and all related
    expenses.

b)  On or about April 18, 1997, Howard Katz, Realprop Capital Corporation and
    Evelyn Katz commenced an action against, among others, the Company, Stephen
    A. Garofalo, Peter Sahagen and Peter Silverman in the United States
    District Court for the Southern District Court of New York captioned KATZ,
    ET AL. V. NATIONAL FIBER NETWORK, INC., ET AL., No. 97 Civ. 2764 (JGK) (the
    "Katz Litigation").  On May 28, 1997, the plaintiffs filed an amended
    complaint and on September 15, 1997, the plaintiffs filed a second amended
    complaint.  The complaint as amended alleges causes of action for, among
    other things, common law fraud, violations of Section 10(b) of the
    Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder,
    breach of fiduciary duty and negligent misrepresentation for alleged
    misrepresentations and omissions made in connection with the repurchase of
    a right to purchase an aggregate of 264,631 shares of Class A common stock
    of the Company, which class of shares was authorized in October 1997, and
    an option to purchase warrants for the purchase of 207,888 shares of Class
    A common stock.  The amended complaint also contains allegations of
    corporate waste against the Company and Stephen A. Garofalo.  Plaintiffs
    seek, among other things, compensatory damages of not less than $12
    million, punitive damages in the amount of $100 million and, in the
    alternative, rescission of the purchase of the common stock and warrants by
    the Company.  On June 11, 1997, various defendants, including the Company
    and Stephen A. Garofalo moved to dismiss the amended complaint.  The
    Company intends to vigorously defend itself against these allegations based
    on its belief that the Company acted appropriately in connection with the
    matters at issue in this litigation.  No assurance can be made, though,
    that the Company will not determine that the advantages of entering into a
    settlement outweigh the risk and expense of protracted litigation or that
    ultimately the Company will be successful in its defense of the
    allegations.  If the Company is unsuccessful in its defense of the
    allegations, an award of the magnitude being sought by the plaintiffs in
    the Katz Litigation would have a material adverse effect on the Company's
    financial condition or results of operations. 

c)  On or about October 20, 1997, Vento & Company of New York, LLC ("VCNY")
    commenced an action against the Company, Stephen A. Garofalo, Peter
    Silverman, the law firm of Silverman, Collura, Chernis & Balzano, P.C.,
    Peter Sahagen, Sahagen Consulting Group of Florida (collectively, the
    "Sahagen Defendants") and Robert Kramer, Birdie Capital Corp, Lawrence
    Black, Sterling Capital LLC, Penrush Limited, Needham Capital Group, Arthur
    Asch, Michael Asch and Ronald Kuzon (the "Kramer Defendants") in the United
    States District Court for the Southern District of New York (No. 97 CIV
    7751) (the "VCNY Litigation").  The complaint alleges causes of action for,
    among other things, violation of Section 10(b) of the Securities Exchange
    Act of 1934 and Rule 10b-5 promulgated thereunder, fraud and fraudulent
    concealment, breach of fiduciary duty and negligent misrepresentation and
    omission made in connection with respect to the sale by VCNY of 1,368,900
    shares of Class A common stock to Peter Sahagen and the Kramer Defendants
    on January 13, 1997 (the "VCNY Sale").  The complaint also alleges a cause
    of action for declaratory judgement asserting that certain "piggyback"
    registration rights are applicable to shares of the Company's Class A
    common stock which VCNY owns (or which may be rescinded to VCNY pursuant to
    its requested  remedies).  The complaint further requests a declaratory
    judgement that a stockholders' agreement

ITEM 1. LEGAL PROCEEDINGS  (CONTINUED)

    between the Company, Stephen A. Garofalo and VCNY be declared operative,
    which agreement indirectly required VCNY, through designated directors to
    approve significant transactions, and, accordingly, the Metromedia Loan and
    the Metromedia Investment should be rescinded and Mr. Vento should be
    reappointed as Chief Executive Officer of the Company.  The Company
    believes, among other things, that the stockholder's agreement to which Mr.
    Vento was a party had terminated and, as a result, Mr. Vento had no such
    rights to approve the Metromedia Investment or the Metromedia Loan or to
    remain as Chief Executive Officer of the Company. Plaintiff seeks, among
    other things, (i) rescission of the VCNY Sale, or alternatively, damages in
    an amount not presently ascertainable, but believed to be in the excess of
    $36 million, together with interest thereon, (ii) punitive damages in the
    amount of $50 million, and (iii) the declaratory judgements discussed
    above.  The Company intends to vigorously defend itself against these
    allegations based on its belief that it acted appropriately in connection
    with the matters at issue in this litigation.  However, no assurance can be
    made that the Company will not determine that the advantages of entering
    into a settlement outweigh the risk and expense of protracted litigation or
    that ultimately the Company will be successful in its defense of the
    allegations. If the Company is unsuccessful in its defense of the
    allegations, an award of the magnitude being sought by the plaintiffs in
    the VCNY Litigation would  have a material adverse effect on the Company's
    financial condition or results of operations.
