                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)


Note 1 -  Basis of presentation
--------------------------------

The accompanying unaudited consolidated financial statements include the
accounts of Granite Broadcasting Corporation and its subsidiaries (the
"Company"), have been prepared in accordance with the instructions to Form 10-Q
and do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements.  Operating
results for the three month period ended March 31, 1997 are not necessarily
indicative of the results that may be expected for the year ended December 31,
1997.  For further information, refer to the Company's consolidated financial
statements and notes thereto for the year ended December 31, 1996 which were
included in the Company's Annual Report on Form 10-K for the year ended December
31, 1996. All significant intercompany accounts and transactions have been
eliminated. Data at and for the year ended December 31, 1996 are derived from
the Company's audited consolidated financial statements.

In the opinion of management, all adjustments of a normal recurring nature which
are necessary for a fair presentation of the results for the interim periods
have been made.

Note 2 - Acquisitions
---------------------

On January 31, 1997, the Company acquired substantially all of the assets of
WXON-TV, the WB affiliate serving Detroit, Michigan, for $175,000,000 and the
assumption of certain liabilities.  The Company financed the acquisition by
borrowing approximately $27,500,000 under its credit agreement and issuing
150,000 shares of its 12-3/4% Cumulative Exchangeable Preferred Stock, par value
$0.01 per share (the "New Preferred Stock"), at $1,000 per share.  Dividends on
the New Preferred Stock are payable semi-annually on April 1 and October 1 and
may be paid, at the Company's option, either in cash or by the issuance of
additional shares of New Preferred Stock.

Note 3 - Long term debt
-----------------------

In March 1997, the Company purchased $19,405,000 face amount of its 9-3/8%
Senior Subordinated Notes due December 1, 2005 (the "9-3/8% Notes") at a
discount. As a result, the Company recognized an extraordinary loss, after the
write-off of a portion of related deferred financing fees, of $320,804.

Note 4 -  Net loss per common share
-----------------------------------

Net loss per common share for the three months ended March 31, 1997 and 1996 is
calculated by dividing net loss attributable to common stockholders by the
weighted average number of shares of common stock outstanding. The inclusion of
additional shares assuming the exercise of outstanding stock options and the
conversion of certain preferred stock into Common Stock (Nonvoting) would have
been antidilutive for both periods presented.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128 "Earnings Per Share" (FAS 128),which establishes new standards for computing
and presenting earnings per share.  FAS 128 is effective for financial
statements issued for periods ending after December 15, 1997, including interim
periods.  Management does not believe that the implementation of FAS 128 will
have a material impact on the Company's per share amounts.

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

Introduction
------------

The consolidated financial statements of the Company reflect increases between
the three month periods ended March 31, 1997 and 1996 in substantially all line
items.  The principal reasons for such increases are the acquisition of WXON-TV
on January 31, 1997 and the operation of WLAJ-TV under a time brokerage
agreement which commenced in October 1996.   It is anticipated that the
Company's consolidated financial statements for the year ended December 31, 1997
will reflect significant increases in substantially all line items compared to
the prior year due to the acquisition of WXON-TV and the operation of WLAJ-TV.

The Company's revenues are derived principally from local and national
advertising and, to a lesser extent, from network compensation for the broadcast
of programming and revenues from studio rental and commercial production
activities.  The primary operating expenses involved in owning and operating
television stations are employee salaries, depreciation and amortization,
programming and advertising and promotion expenses.  Numbers referred to in the
following discussion have been rounded to the nearest thousand.

The following table sets forth certain operating data for the three months ended
March 31, 1997 and 1996:

</TABLE>

"Broadcast cash flow" means operating income plus time brokerage agreement fees,
depreciation, amortization, corporate expense and non-cash compensation. The
Company has included broadcast cash flow data because such data are commonly
used as a measure of performance for broadcast companies and are also used by
investors to measure a company's ability to service debt. Broadcast cash flow is
not, and should not be used as, an indicator or alternative to operating income,
net income or cash flow as reflected in the consolidated financial statements,
is not a measure of financial performance under generally accepted accounting
principles and should not be considered in isolation or as a substitute for
measures of performance prepared in accordance with generally accepted
accounting principles.

Three months ended March 31, 1997 and 1996
------------------------------------------

Net revenue for the three months ended March 31, 1997 totaled $32,298,000, an
increase of $3,668,000 or 13 percent compared to $28,630,000 for the three
months ended March 31, 1996.  Of this increase, $3,581,000 was due to the
inclusion of two months of operations of WXON-TV and three months of operations
of WLAJ-TV. The remaining increase was primarily due to increased local and
national advertising revenue and incremental revenue from the Company's various
internet ventures, partially offset by lower political advertising revenue in a
non-election year.



                                      -6-
<PAGE>
 
Station operating expenses totaled $19,797,000, an increase of $2,279,000 or 13
percent compared to $17,518,000 for the three months ended March 31, 1996.  Of
this increase, $1,367,000 was due to the inclusion of two months of operations
of WXON-TV and three months of operations of WLAJ-TV.  The remaining increase
was primarily due to increased news and administrative expenses, partially
offset by lower promotion expenses.

Depreciation and amortization increased $645,000, or 17% during the three months
ended March 31, 1997 compared to the same period a year earlier primarily due to
the inclusion of two months of operations of WXON-TV.  Corporate expense
increased $484,000 or 49% during the three months ended March 31, 1997 compared
to the same period a year earlier, primarily due to higher administrative costs
associated with the expansion of the Company's corporate office to manage its
expanded station group.  Non-cash compensation expense increased $77,000 or 67%
during the three months ended March 31, 1997 compared to the same period a year
earlier due to the granting of additional awards payable in Common Stock
(Nonvoting) to certain executive employees of the Company under the Management
Stock Plan.

The equity in net loss of investee of $400,000 for the three months ended March
31, 1997 resulted from the Company recognizing its pro rata share of the net
loss of Datacast, LLC under the equity method of accounting.

Net interest expense was $9,778,000 compared to $8,850,000 a year earlier, an
increase of 10 percent, primarily due to the fact that the Company's 9-3/8%
Notes, which were issued on February 22, 1996, were outstanding for a full
quarter.

Loss before extraordinary item for the three months ended March 31, 1997 totaled
$4,957,000 compared to a loss before extraordinary item of $3,454,000 for the
same period a year earlier, an increase of $1,503,000.  The increase was
primarily due to the changes in the line items discussed above.

During the three months ended March 31, 1997, the Company purchased $19,405,000
face amount of its 9-3/8% Notes at a discount and replaced it with borrowings
under its credit agreement which bear interest at a lower rate, thereby reducing
its cost of borrowing.  In conjunction with the repurchase of this debt, the
Company recognized an extraordinary loss, after the write-off of a portion of
related deferred financing fees, of $321,000. During the three months ended
March 31, 1996, the Company repaid all then outstanding term loan and revolving
credit borrowings under its then existing bank credit agreement using the
proceeds from the sales of its 9-3/8% Notes.  In connection with the repayment
of the term loan, the Company incurred an extraordinary loss on the early
extinguishment of debt of $3,510,000 related to the write-off of deferred
financing fees.

Liquidity and Capital Resources
-------------------------------

In October 1996, the Company entered into agreements with the owner of WLAJ-TV,
the ABC affiliate serving Lansing, Michigan, including a time brokerage
agreement pursuant to which the Company operates WLAJ-TV and an agreement to
acquire substantially all the assets used in the operation of WLAJ-TV for
approximately $19.4 million in cash and the assumption of certain liabilities.
The Company anticipates financing the acquisition of WLAJ-TV with borrowings
under its credit agreement's revolving working capital facility.  In connection
with these agreements, the Company agreed to provide a loan guarantee of up to
$12,000,000 in favor of the owner of WLAJ-TV.

On January 31, 1997, the Company acquired substantially all of the assets of
WXON-TV for $175,000,000 and the assumption of certain liabilities.  The Company
financed the acquisition through the sale of 150,000 shares of its New Preferred
Stock at $1,000 per share and borrowings of $27,500,000 under its credit
agreement.


                                      -7-
<PAGE>
 
The Company's existing credit agreement allows for revolving credit borrowings
of $200,000,000 and permits borrowings of up to $300,000,000 in the aggregate.
The revolving credit facility can be used to fund future acquisitions of
broadcast stations and for general corporate purposes.  As of May 10, 1997,
subject to compliance with financial covenants, the Company had $137,000,000 of
the revolving credit facility borrowings available under the credit agreement
available for acquisitions and working capital purposes.

Cash flows provided by operating activities were $8,698,000 during the three
months ended March 31, 1997 compared to cash flows provided by operating
activities of $6,365,000 during the three months ended March 31, 1996, an
increase of $2,333,000 or 37 percent.  The increase was primarily due to higher
broadcast cash flow and a decrease in net operating assets offset, in part, by
higher cash interest expense.

Cash flows used in investing activities were $173,621,000 during the three
months ended March 31, 1997 compared to $1,444,000 during the three months ended
March 31, 1996.  Cash flows used in investing activities during the three months
ended March 31, 1997 related primarily to the acquisition of WXON-TV while cash
flows used in investing activities during the three months ended March 31, 1996
were related entirely to capital expenditures.

Cash flows provided by financing activities were $165,748,000 during the three
months ended March 31, 1997 compared to cash flows used in financing activities
of $661,000 during the three months ended March 31, 1996.  The increase resulted
primarily from the issuance of the 12-3/4% Cumulative Exchangeable Preferred
Stock, an increase in net borrowings and a decrease in payments for deferred
financing fees.

The Company believes that internally generated funds from operations and
borrowings under its credit agreement's revolving working capital facility, if
necessary, will be sufficient to satisfy the Company's cash requirements for its
existing operations for the next twelve months and for the foreseeable future
thereafter.
