             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)


NOTE 1  --  ORGANIZATION AND BASIS OF PRESENTATION
------                                            

         The accompanying unaudited condensed consolidated financial statements
include the consolidated operations, assets and liabilities of Crown Paper Co.,
and Crown Paper Co.'s consolidated subsidiaries. Crown Paper Co. and
subsidiaries  (the "Company") is a wholly owned subsidiary of Crown Vantage Inc.
("Crown Vantage" or "the Parent").  The Parent became an independent company
after James River Corporation of Virginia ("James River"), now known as Fort
James Corporation ("Fort James"), spun off the assets, liabilities and
operations which comprised a substantial part of James River's Communication
Papers Business and the paper-based part of its Food and Consumer Packaging
Business ("Predecessor Business").  At the close of business on August 25, 1995,
James River distributed to its common shareholders all of the outstanding shares
of the Parent (the "Distribution").  The Distribution was made in the form of a
tax-free dividend on the basis of one share of the Parent's common stock for
every ten shares of James River common stock.  A total of 8,446,362 shares of
the Parent's common stock was issued and began trading on NASDAQ on August 28,
1995.

     The accompanying condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X.  Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for annual
financial statements.  The condensed consolidated balance sheet as of December
28, 1997 was derived from audited financial statements, but does not include all
disclosures required by generally accepted accounting principles for annual
financial statements.  In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included.  Operating results for the quarter and nine months ended
September 27, 1998 are not necessarily indicative of the results that may be
expected for the year ended December 27, 1998.  For further information, refer
to the consolidated financial statements and footnotes thereto included in Crown
Paper Co.'s Form 10-K for the year ended December 28, 1997.  Certain 1997
amounts have been reclassified to conform with the 1998 presentation.

NOTE 2  --  INCOME TAX
------                

     The income tax benefits for the quarter and nine months ended September 27,
1998 and September 28, 1997 were provided based on the Company's estimated
annual tax rates of 35% and 36%, respectively.

</TABLE>

     On March 18, 1998, Crown Vantage and the Company entered into an agreement
with Fort James related to Crown Vantage's 11.45% Senior Pay-in-Kind Notes ("PIK
Notes") which are held by Fort James. The agreement provided for the delivery to
Crown Vantage and Crown Paper Co. of PIK Notes totaling $25 million and $8
million, respectively, in exchange for the mutual release from a variety of
claims that had arisen from prior transactions between Fort James, Crown Vantage
and the Company. On September 28, 1998 Crown Vantage, the Company and Fort James
consummated the settlement agreement whereby Fort James returned the $33 million
of PIK Notes. Crown Vantage has the right to purchase the remaining PIK Notes
and accrued interest (the notes having a face amount totaling $107 million at
September 27, 1998) at fair value (see Note 10 "Subsequent Events").

     Maturities of long-term debt, excluding the revolving credit, for the next
five fiscal year ends are:  1999 - $1.0 million; 2000 - $1.3 million; 2001 - $.8
million; 2002 - $47.0 million and 2003 - $47.5 million.

NOTE 5  --  LITIGATION AND ENVIRONMENTAL MATTERS
------                                          

   The Company is a party to various legal proceedings generally incidental to
its business and is subject to a variety of environmental protection statutes
and regulations.  As is the case with other companies in similar industries, the
Company faces exposure from actual or potential claims and legal proceedings
involving environmental matters.  Although the ultimate disposition of legal
proceedings cannot be predicted with certainty, it is the present opinion of the
Company's management that the outcome of any claim which is pending or
threatened, either individually or on a combined basis, will not have a
materially adverse effect on the consolidated financial position of the Company
but could materially affect consolidated results of operations in a given year.

                                       7
<PAGE>
   The Company has accrued estimated landfill site restoration, post-closure and
monitoring costs totaling $12.0 million at September 27, 1998 and December 28,
1997.  In addition, the Company has been identified as a potentially responsible
party ("PRP"), along with others, under the Comprehensive Environmental
Response, Compensation and Liability Act or similar federal and state laws
regarding the past disposal of wastes at 20 sites in the United States.  The
Company has previously settled its remediation obligations at 12 of those sites.
At 7 other sites, the Company is one of many potentially responsible parties and
its alleged contribution to the site and remediation obligation is not
considered significant.  At one other site, remedial investigation is underway
and a loss estimate for the potential remediation effort costs is not yet
possible.  However, the Company's accrual for the remediation investigation
effort was $.2 million at September 27, 1998 and $.6 million at December 28,
1997.  The liabilities can change substantially due to such factors as the
solvency of other potentially responsible parties, the Company's share of
responsibility, additional information on the nature or extent of contamination,
methods and associated costs of remediation required, and other actions by
governmental agencies or private parties.  While it is not feasible to predict
the outcome of all environmental liabilities, based on its most recent review,
management estimates the Company's share of the costs of investigation and
remediation of the known sites will not have a material adverse effect upon the
consolidated financial condition of the Company.

   Due to uncertainties associated with remediation activities, regulations,
technologies, and the allocation of costs among various other parties, actual
costs to be incurred at identified sites may vary from estimates.  Therefore,
management is unable to determine if the ultimate disposition of all known
environmental liabilities will have a material adverse effect on the Company's
consolidated results of operations in a given year.  As with most manufacturing
and many other entities, there can be no assurance that the Company will not be
named as a PRP or incur liabilities through other means at additional sites in
the future or that the costs associated with such additional sites would not be
material.

   The Environmental Protection Agency signed final rules affecting pulp and
paper industry discharges of wastewater and gaseous emissions ("Cluster Rules")
which became effective on April 15, 1998.  These Cluster Rules require changes
in the pulping, bleaching and/or wastewater treatment processes presently used
in some U.S. pulp and paper mills, including some of the Company's mills.  Based
on management's understanding of the rules, the Company estimates that
approximately $40 million of capital expenditures may be required to comply with
the rules with compliance dates beginning in 1999 and extending over the next
two to five years.  As of September 27, 1998 the Company has incurred $2.4
million in capital expenditures for compliance with the Cluster Rules.  There
are risks and uncertainties associated with the Company's estimate that could
cause total capital expenditures and timing of such expenditures to be
materially different from current estimates, including changes in technology,
interpretation of the rules by government agencies that is substantially
different from the Company's interpretation, or other items.

NOTE 6 -- STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 121
------                                                       

   Statement of Financial Accounting Standards No. 121 ("Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of")
requires that the Company assess the recoverability of its investments in long-
lived assets to be held and used in operations whenever events or circumstances
indicate that their carrying amounts may be impaired.  Such assessment requires
that the future cash flows expected to result from use of the assets are
estimated and an impairment loss recognized when future cash flows are less than
the carrying value of such assets.  Estimating future cash flows requires the
Company to estimate useful lives of its long-lived assets, future production
volumes and costs, future sales volumes, demand for the Company's product mix
and prices that reflect the use of its long-lived assets and market conditions.
Although the Company believes it has a reasonable basis for its estimates, it is
reasonably possible that the Company's estimate of future cash flows could
change from current estimates which could result in recognizing, in future
periods, a material impairment loss on its long-lived assets.

<PAGE>
NOTE 7 -- COMPREHENSIVE INCOME
------                        
 
   The Company adopted Statement of Financial Accounting Standards No. 130
("SFAS No. 130") "Reporting Comprehensive Income" in the first quarter of 1998.
SFAS No. 130 establishes standards for the reporting and displaying of
comprehensive income and its components; however, the adoption of SFAS No. 130
had no impact on the Company's net income or shareholder's equity.
Comprehensive income for the Company consists of net income, foreign currency
translation adjustments and minimum pension liability adjustments.

   During the third quarter of 1998 and 1997, the Company's total comprehensive
loss was $3.1 million and $5.8 million, respectively, and for the nine months
ended September 27, 1998 and September 28, 1997, the Company's total
comprehensive loss was $24.5 million and $23.6 million, respectively.

NOTE 8  WORK FORCE REDUCTION
------                      

   During the second quarter of 1998 the Company accrued approximately $2.5
million relating to the announced work force reduction of 5%. An additional $.5
million was accrued for the work force reduction effort during the third quarter
of 1998. The accrual is for anticipated expenses resulting from the work force
reduction primarily for severance and benefit payments to the approximately 230
affected employees. Employment classes affected include both hourly and salaried
employees from manufacturing, maintenance, and office staff. As of September 27,
1998 approximately $.9 million had been paid and the remainder will be paid
through the first half of 1999.

NOTE 9  SUBSEQUENT EVENTS
------                   

   On September 28, 1998 Crown Paper Co. received consents from holders of its
11% Senior Subordinated Notes due 2005 and Crown Vantage Inc. and Crown Paper
Co. consummated the settlement with Fort James Corporation for the return of $33
million of Crown Vantage's 11.45% Senior Pay-In-Kind Notes (the "PIK Notes").
The Company's bank lenders also provided their consent. The consents were for
amendments of certain terms of the related indentures and Credit Agreement to
permit the settlement to occur. The settlement involved the return of these PIK
Notes by Fort James in exchange for the mutual release from a variety of claims
that had arisen from prior intercompany transactions. The settlement also
amended the terms of the remaining PIK Notes allowing Crown Vantage the right to
call the remaining PIK Notes and accrued interest at fair value at any time
prior to their maturity.

     Crown Paper Co. expects to record a pretax extraordinary gain in the fourth
quarter of 1998 of approximately $8 million, which will be partially offset by
transaction fees. PIK Notes with combined face values of approximately $25
million were extinguished by Crown Vantage.  The remaining $8 million in
returned PIK Notes is carried on the books of Crown Paper at face value, but
will be eliminated in the consolidated Crown Vantage financial statements.

   Crown Vantage also announced on September 28, 1998 that it would not exercise
the option portion of the settlement agreement which would have allowed for the
return of the remaining PIK Notes with a face value of $107 million held by Fort
James.  The option, which expired on September 30, 1998, would have allowed 
Crown Vantage to purchase these notes for $80 million in cash.  However, Crown 
Vantage continues to hold the right to call these notes at any time prior to
maturity at fair value.

books, custom business forms and corporate communications and promotions (e.g.,
annual reports and stationery); and  (ii) specialty papers, principally for food
and retail packaging applications and conversion into such items as coffee
filters, cups and plates.

   The Company operates 10 facilities using 31 paper machines and its paper
production is approximately 75% integrated with the Company's pulp operations.
The Company's two largest facilities are integrated operations located in St.
Francisville, Louisiana and Berlin and Gorham, New Hampshire.  St. Francisville
produces coated groundwood papers for magazines and catalogs and uncoated
specialty converting papers.  Berlin-Gorham primarily produces uncoated printing
and publishing papers as well as  market pulp.  The Company also produces
uncoated printing and publishing papers at its non-integrated facilities in
Adams, Massachusetts; Ypsilanti, Michigan; and Dalmore and Guardbridge,
Scotland.  The Company's food and retail packaging papers are produced primarily
at non-integrated facilities in Port Huron and Parchment, Michigan, and Milford,
New Jersey.  In addition to its primary paper-making operations, the Company
operates a cast-coating facility in Richmond, Virginia.

NET SALES
---------

          The Company's net sales decreased 4.6% to $649.0 million for the nine
months ended September 27, 1998 as compared to $680.4 million for the same
period in 1997. The decrease in net sales is primarily due to a 3.3% decrease in
tons sold during the first nine months of 1998 compared to the first nine months
of 1997.  Net sales declined 6.6% during the third quarter of 1998 as compared
to the third quarter of 1997.  The decrease in net sales during the third
quarter of 1998 as compared to the same period in 1997 is primarily due to a
3.1% decrease in tons sold and a 3.7% decrease in average net sales price per
ton.

          Net sales of coated groundwood paper (which is used principally in the
production of magazines and catalogs) for the nine month period ending September
27, 1998 increased 20.3% as compared to the same period in 1997.  The increase
in net sales is primarily due to an 18.5% increase in average net sales price
per ton when comparing the first nine months of 1998 to the same period in 1997.
Net sales increased 14.4% during the third quarter of 1998 as compared to the
third quarter of 1997.  The increases in net sales during the third quarter of
1998 as compared to the third quarter of 1997 are primarily due to average net
sales price per ton increasing 9.6% and tons sold increasing by 3,100 tons or
4.4% during the comparable periods. While demand for coated groundwood papers
was strong in the third quarter of 1998, coated paper imports continued at high
levels resulting in industry-wide mill inventory builds and some price
discounting during the quarter.  The current oversupply poses a threat of
continued price discounting which may negatively impact prices of the Company's
coated groundwood paper in future periods.

          Net sales of uncoated printing and publishing papers in the first
three quarters of 1998 decreased 5.1% compared to the first three quarters of
1997.  The decrease in the first nine months of 1998 from the first nine months
of 1997 is primarily due to an average sales price per ton decrease of 3.9%.
Net sales during the third quarter of 1998 decreased 9.5% as compared to the
third quarter of 1997.  The decrease in net sales is primarily due to a 7.1%
decrease in average net sales price per ton and a decrease of approximately
1,500 tons (or 2.5%) during the third quarter of 1998 as compared to the third
quarter of 1997.  The current economic crisis in Asia coupled with a strong U.S.
Dollar and British Pound have 

                                       11
<PAGE>
 
resulted in lower exports by U.S. and U.K. paper producers and increased
imports into the U.S. and U.K. from Asia, Europe, and South America. This
abundance of uncoated freesheet paper supply has negatively impacted demand and
pricing for the Company's uncoated printing and publishing papers, resulting in
depressed prices for the Company's targeted grades. The current supply levels of
these papers in the market place have also resulted in the Company's partial
shift in mix to lower value added grades in order to maintain volume during this
period of supply/demand imbalance, which also negatively impacted the Company's
average net selling price.

          Food and retail packaging paper net sales declined $22.3 million
during the first nine months of 1998, as compared to the same period in 1997.
The 10.0% decrease in net sales is the result of an 8.5% decrease in tons sold
and a 1.6% decrease in average net sales price per ton during the nine months
ended September 27, 1998 as compared to the nine months ended September 28,
1997.  Net sales during the third quarter of 1998 decreased 9.8% or $7.1 million
as compared to the third quarter of 1997.  The decrease in net sales during the
third quarter of 1998 as compared to the same period in 1997 is due to a 8.8%
decrease in tons sold and a 1.1% decrease in average net sales price per ton.
The current economic crisis in Asia is indirectly affecting the Company's food
and retail packaging papers sector as large integrated mills are entering
otherwise non-traditional markets thereby disrupting supply/demand balance and
pricing for the Company's specialty packaging papers.

          Net sales of specialty converting papers decreased 29.2% during the
nine months ended September 27, 1998 compared to the nine months ended September
28, 1997.  Net sales decreased 27.4% to $27.2 million from $37.4 million for the
quarters ended September 27, 1998 and September 28, 1997, respectively.  The
decrease during the first three quarters of 1998 compared to the first three
quarters of 1997 is primarily the result of a 19.4% decrease in tons sold and a
decrease of 12.1% in average net sales price per ton.  The decrease in net sales
during the third quarter of 1998 compared to the third quarter of 1997 is due to
an average price per ton decrease of 12.9% and a decrease in tons sold of 16.6%.
The decreased volume is primarily due to the decision by certain customers
during the last half of 1997 to integrate backwards their operations, negatively
affecting our specialty converting papers sales.  The decrease in average net
sales price per ton is primarily due to the lower number of tons sold from the
Company's cast-coating operations whose papers generally command premium pricing
and the competitive pricing pressures for toweling and certain paper grades
produced at the Company's St. Francisville mill. The Company continues to
aggressively pursue replacing the lost tonnage with new product development and
trials of engineered papers in progress. However, demand for the cast-coated
products remains particularly weak with marginal improvement expected in the
fourth quarter of 1998 and 1999 as compared to the first three quarters of 1998.

          Net sales of pulp to external customers increased by $4.2 million
during the nine months ended September 27, 1998 as compared to the nine months
ended September 28, 1997.  Tons of pulp sold is a function of market demand as
well as managing, to the Company's best advantage, internal pulp integration.
Tons sold to external customers in the first nine months of 1998 increased 37.0%
or 15,000 tons when compared to the same period of 1997.  The increase in tons
sold is primarily due to the availability of pulp for sale that in the prior
period was used internally, primarily for the manufacturing of toweling, as well
as improved operating efficiencies at the pulping operations.  Net sales to
external customers increased 3.0% during the third quarter of 1998 as compared
to the third quarter of 1997.  The increase in net sales is primarily due to an
increase in tons sold of 3,200 tons, for the reasons discussed above, and was
partially offset by a decrease in net sales price per ton of 13.8%.

</TABLE>

          The Company had an operating loss of $2.9 million for the nine months
ended September 27, 1998 compared to operating income of $5.8 million for the
same period in 1997.  Lower volumes and the decrease in average net sales price
in the first nine months of 1998 increased the operating loss by $11.1 million
and $8.8 million, respectively, as compared to the same period in 1997.  The
negative volume and price variances were partially offset by $14.1 million of
favorable cost variances primarily caused by lower raw material costs and
improved operating efficiencies.  The improved cost variances were partially
offset by the workforce reduction accrual taken in the second and third quarters
of 1998 for a total of $3.0 million.  The 11.1% decrease in operating profit
when comparing the third quarter of 1998 to the third quarter of 1997 is
primarily due to the decrease in volume and average net sales price and is
partially offset by the favorable cost variances discussed above.

          Operating performance for printing and publishing papers improved by
$12.4 million to operating income of $4.1 million during the first nine months
of 1998 compared to an operating loss of $8.3 million for the same period in
1997.  The improved operating results were primarily due to the increase in
coated groundwood average price per ton that was partially offset by the
decrease in average price per ton for the Company's uncoated freesheet papers.
The improved operating performance was also negatively impacted by higher costs
due to the work force reduction accrual, and unexpected down time in the second
quarter of 1998 at St. Francisville caused by explosions of transformers owned
by a local utility company. Operating income increased by $4.6 million during
the third quarter of 1998 as compared to the third quarter of 1997 primarily due
to the increase in average net sales price per ton for coated groundwood paper.
The improved results for the third quarter of 1998 were partially offset by
lower uncoated freesheet prices and lower volumes, discussed above.

          Food and retail packaging operating income decreased $5.1 million to
$.8 million for the first nine months of 1998 compared to the first nine months
of 1997.  The decrease in operating income during this period is primarily
attributable to the decreases in volume and average sales price per ton
discussed previously in "Net Sales." The decreases in volumes and prices were
partially offset by favorable cost variances primarily from improved mill
efficiencies and lower raw material costs. Operating income decreased $1.4
million during the third quarter of 1998 as compared to the third quarter of
1997 for the reasons discussed above.

          Operating results for converting papers decreased $8.9 million in the
first nine months of 1998 as compared to the first nine months of 1997.
Operating results decreased $2.2 million during the third quarter of 1998
compared to the third quarter of 1997.  The decrease in operating results is
primarily attributable to the decrease in tons sold and the lower average price
per ton discussed previously.

     Operating results within the Company's pulp and miscellaneous sector
decreased approximately $ 7.1 million for the first nine months of 1998 compared
to the first nine months of 1997.  The decline in 

                                       13
<PAGE>
 
operating results was primarily the result of decreases in average net sales
price per ton and certain manufacturing difficulties encountered during the
first two quarters of 1998. Average net sales price per ton for pulp decreased
6.5% during the first nine months of 1998 as compared to the first nine months
of 1997. Operating results during the third quarter of 1998 compared to the
third quarter of 1997 decreased by $1.8 million primarily due to a 13.8%
decrease in average net sales price per ton.

          Selling and administrative expenses increased $2.8 million for the
first nine months of 1998 compared to the same period in 1997.  The increase in
selling and administrative expense when comparing the first nine months of 1998
to the first nine months of 1997 is primarily due to higher sales and marketing
costs and one time expenditures associated with certain of the Company's
strategic initiatives.  Selling and administrative expenses increased $1.8
million when comparing the third quarters of 1998 and 1997 primarily due to the
one time expenditures associated with certain of the Company's strategic
initiatives.

INTEREST EXPENSE
----------------

          Interest expense for the nine months ended September 27, 1998 and
September 28, 1997 was $36.9 million and $38.1 million, respectively.  Interest
expense for the third quarters of 1998 and 1997 was $12.5 million and $13.0
million, respectively.

LIQUIDITY AND SOURCES OF CAPITAL
--------------------------------

          In connection with the Spin-Off, the Company obtained $250 million in
financing through a public offering of Senior Subordinated Notes and $253
million initial borrowings under a $350 million credit facility from a group of
banks (collectively, the "Financing").  The net proceeds from the Financing were
paid to James River Corporation of Virginia, now known as Fort James Corporation
("Fort James"), together with $100 million Senior Pay-in-Kind Notes issued by
the Parent as a return of James River's capital investment.

     On March 18, 1998, Crown Vantage and the Company entered into an agreement
with Fort James related to Crown Vantage's 11.45% Senior Pay-in-Kind Notes ("PIK
Notes") which are held by Fort James. The agreement provided for the delivery to
Crown Vantage and Crown Paper Co. of PIK Notes totaling $25 million and $8
million, respectively, in exchange for the mutual release from a variety of
claims that had arisen from prior transactions between Fort James, Crown Vantage
and the Company. On September 28, 1998 Crown Vantage, Crown Paper Co. and Fort
James consummated the settlement agreement whereby Fort James returned the $33
million of PIK Notes. Crown Vantage has the right to purchase the remaining PIK
Notes and accrued interest (the notes having a face amount totaling $107 million
at September 27, 1998) at fair value (see "Subsequent Events").

     Under the bank credit facility the revolving credit available is in the
aggregate amount of $150 million with a $75 million sublimit for letters of
credit and can be used for general corporate purposes, working capital needs and
permitted investments.  At September 27, 1998, $70.0 million of the revolving
credit was outstanding, $37.9 million of the sublimit for letters of credit had
been used and $42.1 million of the aggregate line was available if needed.

          Cash flows provided by operating activities were $6.8 million for the
nine months ended September 27, 1998 compared to cash flows provided by
operating activities of $29.8 million for the nine months ended September 28,
1997.  The decrease in operating cash flows for the nine months ended September
27, 1998 compared to the same period in 1997 is mainly attributable to the $5.5
million increase in net loss, a $3.3 million reduction in the accounts
receivable securitization and fluctuations in 

                                       14
<PAGE>
 
working capital and other assets and liabilities. Earnings before interest,
taxes, depreciation and amortization (EBITDA) were $61.3 million for the first
nine months of 1998 as compared to $69.1 million for the comparable period in
1997.

          The Company's business is capital intensive.  Pulp and paper mills
generally consist of an extensive network of buildings, machinery, and
equipment, which require continual upgrades, replacement, modernization and
improvement.  The Company's capital expenditures for the nine months ended
September 27, 1998 were $34.1 million compared to $45.0 million in the same
period in 1997.  1998 expenditures primarily represented capital maintenance
projects.  Capital expenditure projects during the first nine months of 1997
related to capital maintenance projects and $7.9 million for cash payments on
the Company's rebuild of the Number 1 paper machine at the St. Francisville
mill.  The Company's capital spending plan for the remainder of 1998 is
approximately $6 million.  These capital expenditures are primarily for capital
maintenance and environmental projects and are expected to be financed by cash
flows from operations and available financing sources.

WORK FORCE REDUCTION
--------------------

          During the second quarter of 1998 the Company accrued $2.5 million
relating to the announced work force reduction of 5%. An additional $.5 million
was accrued for the work force reduction effort during the third quarter of
1998. The accrual is for anticipated expenses resulting from the work force
reduction primarily for severance and benefit payments to the approximately 230
affected employees. Employment classes affected include both hourly and salaried
employees from manufacturing, maintenance, and office staff. As of September 27,
1998 approximately $.9 million had been paid and the remainder will be paid
during the last quarter of 1998 and into the first half of 1999.

EURO CONVERSION
---------------

     The Company is in the process of addressing the issues raised by the
introduction of the Single European Currency ("Euro") as of January 1, 1999 and
during the transition period through January 1, 2002. The Company expects that
its internal systems that will be affected by the initial introduction of the
Euro will be Euro capable by January 1, 1999, and does not expect the costs of
system modifications to be material. While the Company will continue to evaluate
the impact of the Euro introduction over time, based on currently available
information, management does not believe that the introduction of the Euro
currency will have a material adverse impact on the Company's financial
condition or overall trends in results of operations.

YEAR 2000
---------

     The Year 2000 issue concerns the potential inability of computer
applications, other information technology systems, and certain software-based
"embedded" control systems to recognize and process properly date-sensitive
information as the Year 2000 approaches and beyond.  The Company could suffer
material adverse impacts on its operations and financial results if the
applications and systems used by the Company, or by third parties with whom the
Company does business, do not accurately or adequately process or manage dates
or other information as a result of the Year 2000 issue.

          The Company has completed a review of its financial accounting system
for purposes of evaluating the Year 2000 issue.  The Company's software provider
has indicated that it will certify this financial accounting system as Year 2000
compliant upon completion of the next scheduled upgrade.  This upgrade is
scheduled for completion during the first quarter of 1999.  Management expects
this upgrade will adequately address the Year 2000 issue in this system.
Independent testing will be 

                                       15
<PAGE>
 
performed by the Company. There can be no assurance that all Year 2000 issues in
this software will be adequately resolved by this or other future software
releases.

          The Company also uses a variety of other software applications,
business information systems, accounting subsystems, process control systems and
related software, communication devices, and networking and other operating
systems.  The Company has completed its inventory of all such systems and is
currently in the process of testing, upgrading, replacing, or otherwise
modifying these systems to adequately address the Year 2000 issue. The Company
believes it will be able to timely modify or replace its affected systems to
prevent any material detrimental effects on operations and financial results.
The Company anticipates this work will continue, with appropriate testing,
remediation and/or replacement taking place during the fourth quarter of 1998
and into the first half of 1999.   Possible risks of this process include but
are not limited to the ability of the Company's personnel and outside vendors to
adequately and timely identify and resolve all critical Year 2000 issues, and
the ability of the Company to secure additional Year 2000 expertise during this
time of high demand for this expertise if an unanticipated material problem
requires skills the Company or its third party vendors currently do not possess.
The Company can give no assurance that all critical Year 2000 issues will be
resolved in a timely manner or that potentially unresolved issues would not have
a material adverse impact on the results of operations.

     The Company has certain key relationships with customers, vendors and
outside service providers. Failure by the Company's key customers, vendors and
outside service providers to adequately address the Year 2000 issue could have a
material adverse impact on the Company's operations and financial results. The
Company is currently assessing the Year 2000 readiness of these key customers
and suppliers and, at this time, cannot determine what the impact of this
assessment will be on the Company.  This assessment includes but is not limited
to soliciting responses from each of these parties concerning their Year 2000
readiness and review of public documents filed by many of these parties.
Management expects to complete the assessment of these key suppliers during the
first quarter of 1999.  The Company is primarily relying upon the voluntary
disclosures from third parties for this review of their Year 2000 readiness.

     Since the Company anticipates that its affected systems will be remediated
or replaced to timely address the Year 2000 issue and is currently focusing its
resources in those areas, the Company has not yet developed any other
contingency plans regarding the Year 2000 issue for its internal systems.
However, the Company intends to develop contingency plans if at a later date
management determines that any of its systems will not be Year 2000 compliant
and that such noncompliance would be expected to have a material adverse impact
on the Company's operations or financial results.  Many of the identified risks
from key customers, vendors and outside service providers are both general and
speculative in nature, such as possible power or telecommunication failures,
breakdowns in transportation systems, inability to process financial
transactions, and similar events affecting general business services.  The
Company has not developed any contingency plans for these general risks, is not
currently able to ascertain the likelihood that any of these risks will actually
occur, and has not otherwise analyzed or identified possible "worst case"
scenarios relating to Year 2000 issues.  Once the Company has completed its
assessment of Year 2000 readiness of key customers, vendors and outside service
providers, management intends to develop contingency plans to mitigate material
known detrimental effects that may be caused by their Year 2000 noncompliance.
However, it is unlikely that any contingency plan would mitigate the adverse
impact to the financial condition or operations of the Company of any
catastrophic event due to the Year 2000 issue that leads to a prolonged
disruption of essential services.

                                       16

     Management believes that total Year 2000 costs will range between $2
million and $3 million, most of which will be incurred in 1998.  The costs
associated with this effort are incremental to the Company.   As of September
27, 1998 the Company has incurred costs related to the Year 2000 issue of
approximately $.7 million.  In addition to the costs mentioned above, the
Company's capital spending for planned upgrading of certain information systems
to enhance the capabilities of those systems was accelerated in part due to the
Year 2000 issue.  The total estimated increase in accelerated capital spending
for these systems is anticipated to be under $2 million.  The Company's current
estimates of the amount of time and costs necessary to remediate and test its
computer systems are based on the facts and circumstances existing at this time.
The estimates were made using assumptions of future events including the
continued availability of certain resources, Year 2000 readiness plans,
implementation success by key third party vendors, and other factors.  New
developments may occur that could increase the Company's estimates of the amount
of time and costs necessary to modify and test its various information and non-
information systems.  These potential developments include but are not limited
to the availability and increased cost of personnel trained in this area of
expertise, the ability to locate and correct all relevant computer codes and
equipment, and any unanticipated Year 2000 problems from key customers, vendors,
and outside service providers.

DEBT COVENANTS
--------------

     In connection with the bank credit facility as amended (the "Facility"),
the Company is required to comply with certain financial covenants that include
maintaining minimum quarterly cash flow to debt and interest coverage ratios as
well as minimum tangible net worth.  The Company is currently in compliance with
these covenant requirements.  Pursuant to the Facility, the covenant
requirements are scheduled to become significantly more onerous at the end of
the first quarter of fiscal year 1999.  Based on management's current forecasts,
it is probable that the Company will not be in compliance with the new financial
covenants referred to above at the end of the first quarter of 1998.  In
addition, should the current pricing environment for the Company's products not
sufficiently improve during the remainder of 1998, it is reasonably possible
that the Company will not be in compliance with certain of its financial
covenants at the end of the fourth quarter of 1998.  Management is currently in
the process of renegotiating its debt covenants with the bank group.  While
there can be no assurance of success, management believes that it will be
successful in amending the financial covenants in order to maintain compliance
with the Facility.

NEW ACCOUNTING PRONOUNCEMENTS
-----------------------------

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131 ("SFAS No. 131") "Disclosure about
Segments of an Enterprise and Related Information."  This statement will require
segment disclosure based on management's decision-making criteria.  SFAS No. 131
also requires disclosures about the products and services provided, the
countries in which material assets are held and material revenues are generated,
and significant customers.  Management has determined that the Company has two
reportable segments under SFAS 131: Specialty Papers and Printing and Publishing
Papers.  SFAS No. 131 is effective for the Company's 1998 fiscal year end.

SUBSEQUENT EVENTS
----------------- 

     On September 28, 1998 Crown Paper Co. received consents from holders of its
11% Senior Subordinated Notes due 2005 and Crown Vantage Inc. and Crown Paper
Co. consummated the settlement with Fort James Corporation for the return of $33
million of Crown Vantage's 11.45% Senior Pay-In-Kind Notes. The Company's bank
lenders also provided their consent. The consents were for amendments
of certain terms of the
                                       17
<PAGE>
 
related indentures and Credit Agreement to permit the settlement to occur. The
settlement involved the return of these PIK Notes by Fort James in exchange for
the mutual release from a variety of claims that had arisen from prior
intercompany transactions. The settlement also amended the terms of the
remaining PIK Notes allowing Crown Vantage the right to call the remaining PIK
Notes and accrued interest at fair value at any time prior to their maturity.

     Crown Paper Co. expects to record a pretax extraordinary gain in the fourth
quarter of 1998 of approximately $8 million, which will be partially offset by
transaction fees. PIK Notes with combined face values of approximately $25
million were extinguished by Crown Vantage.  The remaining $8 million in
returned PIK Notes is carried on the books of Crown Paper at face value, but
will be eliminated in the consolidated Crown Vantage financial statements.

          Crown Vantage also announced on September 28, 1998 that it will not
exercise the option portion of the settlement agreement for the return of the
remaining PIK Notes with a face value of $107 million held by Fort James.  The
option, which expired on September 30, 1998, would have allowed Crown Vantage to
purchase these notes for $80 million in cash. However, Crown Vantage continues
to hold the right to call these notes at any time prior to maturity at fair
value.

FORWARD LOOKING STATEMENTS
--------------------------

          Certain statements within Management's Discussion and Analysis and
elsewhere are forward looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995.  These statements are subject to
various risks and uncertainties that could cause the actual results to be
materially different from the Company's current expectations.  These forward-
looking statements can be identified by use of language such as plans, expects,
estimates, anticipates, believes, possible and other similar words or phrases.
In addition to the factors discussed above, there are other factors that could
cause the actual results to differ materially.  These other factors include but
are not limited to business conditions and the general economy both global and
domestic, prices for the Company's products, the duration and depth of the Asian
economic crisis, competitive factors, the effects of the spread of the Asian
economic crisis to other regions around the world, maintaining good labor
relations, the Company's ability to successfully implement its Year 2000 plans,
the Company's ability to renegotiate and comply with debt covenants and
maintaining good customer relations.
