                         Report of Independent Auditors


Administrative Committee
Jefferson Smurfit Corporation Retirement Plans

We have audited the accompanying statements of net assets available for plan
benefits of Jefferson Smurfit Corporation Savings Plan as of December 31, 1998
and 1997, and the related statements of changes in net assets available for plan
benefits for the years then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits at December
31, 1998 and 1997, and the changes in its net assets available for plan benefits
for the years then ended, in conformity with generally accepted accounting
principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
held for investment as of December 31, 1998 and schedule of reportable
transactions for the year then ended are presented for purposes of complying
with the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974 and are not
a required part of the financial statements. The fund information in the
statements of net assets available for plan benefits and the statements of
changes in net assets available for plan benefits is presented for purposes of
additional analysis rather than to represent the net assets available for plan
benefits and changes in net assets available for plan benefits of each fund. The
supplemental schedules and fund information have been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, are fairly stated in all material respects in relation to the financial
statements taken as a whole.

                          Notes to Financial Statements

                                December 31, 1998


1. SIGNIFICANT ACCOUNTING POLICIES

The financial statements of Jefferson Smurfit Corporation Savings Plan (the
Plan) are reported on the accrual basis. The current values of investments have
been determined by T. Rowe Price as trustee for 1998 and 1997 and have been
based on closing prices if traded on national stock exchanges or bid prices for
bonds. The immediate participation contracts and participant loans are valued at
cost which approximates market. The differences between the current value and
the cost of investments are reflected in the statements of changes in net assets
available for plan benefits as part of net realized and unrealized appreciation
(depreciation) of investments. The cost of securities sold is based on the
weighted average method.

As of January 1, 1997, the Plan changed the plan trustee from Mercantile Bank of
St. Louis to T. Rowe Price. As of October 1, 1996, funds were transferred into
an omnibus account, and investment options were changed from the various Arch
funds to T. Rowe Price funds.

Administrative expenses are paid by the Plan. In 1997, the Plan changed its
allocation of administrative expenses to participant accounts from a prorated
method to allocating expenses to a participant's most stable fund.

The preparation of financial statements in conformity with generally accepted
accounting principles requires plan management to make estimates and assumptions
that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

2. DESCRIPTION OF THE PLAN

On November 18, 1998, Jefferson Smurfit Corporation merged with Stone Container
Corporation (Stone) (the Merger) and changed its name from Jefferson Smurfit
Corporation to Smurfit-Stone Container Corporation (SSCC). A wholly owned
subsidiary of SSCC, Jefferson Smurfit (U.S.) (JSC (U.S.) is the plan sponsor.
Upon consummation of the Merger, JSC (U.S.) (the Company) and Stone approved the
merger of Stone Container Corporation Deferred Income Savings Plan into the Plan
as of July 1, 1999 (Plan Merger). There are not expected to be changes in the
operation or tax status of the Plan or benefits, eligibility, or vesting for
participants of the Plan.

The Plan is a contributory employee benefit plan of the Company and adopting
subsidiaries and affiliates. The Plan is composed of three components: (i) a
cash or deferred compensation component (401(k) component); (ii) an after-tax
voluntary contribution component (ATC component); and (iii) an employer matching
contribution component.


                                                                              24

                    Notes to Financial Statements (continued)


2. DESCRIPTION OF THE PLAN (CONTINUED)

The Plan is administered by an Administrative Committee (Committee) of SSCC
consisting of officers or other employees of the Company or its adopting
subsidiaries and affiliates. The Committee prescribes forms for use by
participants and may make administrative and procedural recommendations.

Employees eligible to participate in the Plan generally consist of all employees
of the Company and adopting subsidiaries and affiliates, except for (1) those
employees covered by a collective bargaining agreement which provides for
retirement benefits, (2) nonresident aliens, and (3) substantially all hourly
employees.

Under the 401(k) provisions, employees may elect to have a portion of their
salary deferred and contributed to the Plan to be invested in one or more of 15
investment options available under the Plan. The participants' ATC contributions
are invested in one or more of 15 investment options available under the Plan.
Contributions are made semimonthly.

Under the employer contribution provisions, each employer contributes, for each
of its employees who are participants, an amount equal to 65 percent of the
401(k) contributions authorized by such employee for 1998 and 1997,
respectively, to a maximum of $5,000 ($4,750 in 1997) in one calendar year, to
the extent the rate of such contributions, in effect from time to time, does not
exceed 3.9 percent of the participant's compensation (matching contributions).
The 401(k) contributions authorized by a participant in excess of 6 percent of
participant compensation for any pay period are disregarded for purposes of
matching contributions.

Participant contributions to the 401(k) plan which are made via payroll
withholdings are limited to the lesser of $10,000 and $9,500 or 15 percent of
participant compensation for calendar years 1998 and 1997. Participant
contributions to the ATC are limited to 15 percent of participant compensation,
not to exceed 20 percent of participant compensation in total when combined with
401(k) contributions. Total contributions credited to a participant's account
(combined 401(k), ATC, and matching contributions components) are limited to the
lesser of $30,000 or 25 percent of compensation. These limitations are
determined on a calendar year basis.

Terminating participants of the Plan are paid the current value of their 401(k)
account, their ATC account, and the vested portion of their employer match
account. Participants may elect a cash distribution or a stock distribution from
the SSCC Common Stock Fund or the Mobil Stock Fund. All other distributions are
in cash.


                                                                              25

                    Notes to Financial Statements (continued)


2. DESCRIPTION OF THE PLAN (CONTINUED)

Each participant has a fully vested and nonforfeitable interest in the value of
his or her proportional share of the investment funds in which his or her 401(k)
contributions and ATC contributions are invested. Employer contributions vest
over a five-year period based on participant years of service. The nonvested
portion of a terminating participant's account constitutes a forfeiture and is
applied to reduce future employer contributions.

If a participant, who has forfeited all or a part of his or her account, is
reemployed before 60 months have elapsed after his or her employment ended, any
amount he or she forfeited will be restored to his or her account from amounts
forfeited currently by other participants.

Upon enrollment in the Plan, contributions may be directed into the following
funds by the participant or employer:

4. PLAN TAX STATUS

The Internal Revenue Service ruled on May 30, 1996 that the Plan continues to
qualify under Section 401(a) and meets the requirements under Section 401(k) of
the Internal Revenue Code (IRC), and therefore, the related trust is not subject
to tax under present income tax law. The Committee is not aware of any course of
action or series of events that has occurred that might adversely affect the
Plan's qualified status.

Participants are not subject to federal income tax on amounts contributed to
their 401(k) or employer matching contribution accounts under the Plan or on
earnings attributable to such contributions, until such time as these amounts
are distributed to or withdrawn by them.

5. YEAR 2000 (UNAUDITED)

Computer programs which have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. Beginning in the year 2000,
this could result in a system failure or miscalculations causing disruptions of
operations, including a temporary inability to process transactions or engage in
normal business activities.

The Company has completed testing for its internal systems which impact the
processing of transactions on behalf of the Plan. The only major system related
to the Plan which is noncompliant is the payroll system, which is currently in
the process of being updated to a new year 2000-compliant system. The payroll
system and all other systems are expected to be year 2000-compliant by mid-1999.

The Plan has obtained formal communications with its service providers to
determine the extent to which the Plan's interface systems are vulnerable to
those third parties' failure to resolve their own year 2000 issues. The Plan's
review of this communication is expected to be complete by mid-1999.

Substantially all of the costs of the year 2000 inquiries and the systems
updates are being paid by the Company with no effect on plan assets. The Plan
believes the necessary modifications and replacement of computer systems will be
completed in a timely manner, and as a result, the year 2000 issue is not
expected to pose significant operational or financial problems for the Plan.

                         Report of Independent Auditors

Administrative Committee
Jefferson Smurfit Corporation
  Retirement Plans

We have audited the accompanying statements of net assets available for plan
benefits of Jefferson Smurfit Corporation Hourly Savings Plan as of December 31,
1998 and 1997, and the related statements of changes in net assets available for
plan benefits for the years then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits at December
31, 1998 and 1997, and the changes in its net assets available for plan benefits
for the years then ended, in conformity with generally accepted accounting
principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
held for investment as of December 31, 1998 and schedule of reportable
transactions for the year then ended are presented for purposes of complying
with the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974 and are not
a required part of the financial statements. The fund information in the
statements of net assets available for plan benefits and the statements of
changes in net assets available for plan benefits is presented for purposes of
additional analysis rather than to present the net assets available for plan
benefits and changes in net assets available for plan benefits of each fund. The
supplemental schedules and fund information have been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, are fairly stated in all material respects in relation to the financial
statements taken as a whole.

                          Notes to Financial Statements


                                December 31, 1998



1. SIGNIFICANT ACCOUNTING POLICIES

The financial statements of Jefferson Smurfit Corporation Hourly Savings Plan
(the Plan) are reported on the accrual basis. The current values of investments
have been determined by T. Rowe Price as trustee for 1998 and 1997 and have been
based on closing prices if traded on national stock exchanges or bid prices for
bonds. The differences between the current value and the cost of investments are
reflected in the statements of changes in net assets available for plan benefits
as part of net realized and unrealized appreciation (depreciation) of
investments. The cost of securities sold is based on the weighted average
method.

As of January 1, 1997, the Plan changed the plan trustee from Mercantile Bank of
St. Louis to T. Rowe Price. As of October 1, 1996, funds were transferred into
an omnibus account, and investment options were changed from the various Arch
funds to T. Rowe Price funds.

Administrative expenses are paid by the Plan. In 1997, the Plan changed the
allocation of administrative expenses to participant accounts from a prorated
method to allocating expenses to a participant's most stable fund.

The preparation of financial statements in conformity with generally accepted
accounting principles requires plan management to make estimates and assumptions
that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

2. DESCRIPTION OF THE PLAN

The Plan was established January 1, 1992 and is a contributory employee benefit
plan of Jefferson Smurfit Corporation (Company) and adopting subsidiaries and
affiliates. The Plan is composed of two components: (i) a cash or deferred
compensation component (401(k) component) and (ii) an employer matching
contribution component.


                                                                              22

                    Notes to Financial Statements (continued)


2. DESCRIPTION OF THE PLAN (CONTINUED)

The Plan is administered by an Administrative Committee (Committee) of the
Company consisting of officers or other employees of the Company or its adopting
subsidiaries and affiliates. The Committee prescribes forms for use by
participants and may make administrative and procedural recommendations.

Employees eligible to participate in the Plan consist of those hourly employees
of the Company and adopting subsidiaries and affiliates to whom the terms of the
Plan have been extended including those covered by a collective bargaining
agreement which provides for participation in the Plan.

Under the 401(k) provisions, employees may elect to have a portion of their
wages deferred and contributed to the Plan to be invested in one or more of 15
investment options available under the Plan. Contributions are made every two
weeks or weekly depending upon the plant location.

For those employee groups covered by a collective bargaining agreement providing
for employer contributions, each employer contributes, for each of its employees
who are participants, an amount equal to 50 percent of the 401(k) contributions
authorized by such employee to a maximum dollar amount during one calendar year,
as provided in the collective bargaining agreement.

Participant contributions to the 401(k) which are made via payroll withholdings
are limited to the lesser of $10,000 and $9,500 or 15 percent of participant
compensation for 1998 and 1997, respectively. Total contributions credited to a
participant's account (combined 401(k) and matching contributions components)
are limited to the lesser of $30,000 or 25 percent of compensation. These
limitations are determined on a calendar year basis.

Terminated participants of the Plan are paid the current value of their 401(k)
account and the vested portion of their employer match account. Participants may
elect a cash distribution or a stock distribution from the SSCC Common Stock
Fund. All other distributions are in cash.

Each participant has a fully vested and nonforfeitable interest in the value of
his or her proportional share of the investment funds in which his or her 401(k)
contributions are invested. Employer contributions vest over a five-year period
based on participant years

                                                                              23

of service. The nonvested portion of a terminating participant's account
constitutes a forfeiture and is applied to reduce future employer contributions.
If a participant, who has forfeited all or a part of his or her account, is

4. PLAN TAX STATUS

The Internal Revenue Service ruled on June 17, 1996 that the Plan continues to
qualify under Section 401(a) and meets the requirements under Section 401(k) of
the Internal Revenue Code (IRC), and therefore, the related trust is not subject
to tax under present income tax law. The Administrative Committee is not aware
of any course of action or series of events that has occurred that might
adversely affect the Plan's qualified status.

Participants are not subject to federal income tax on amounts contributed to
their 401(k) or employer matching contribution amounts under the Plan or on
earnings attributable to such contributions, until such time as these amounts
are distributed to or withdrawn by them.

5. YEAR 2000 (UNAUDITED)

Computer programs which have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. Beginning in the year 2000,
this could result in a system failure or miscalculations causing disruptions of
operations, including a temporary inability to process transactions or engage in
normal business activities.

The Company has completed testing for its internal systems which impact the
processing of transactions on behalf of the Plan. The only major system related
to the Plan which is noncompliant is the payroll system, which is currently in
the process of being updated to a new year 2000-compliant system. The payroll
system and all other systems are expected to be year 2000-compliant by mid-1999.

The Plan has obtained formal communications from its service providers to
determine the extent to which the Plan's interface systems are vulnerable to
those third parties' failure to resolve their own year 2000 issues. The Plan's
review of these communications is expected to be complete by mid-1999.

Substantially all of the costs of the year 2000 inquiries and the systems
updates are being paid by the Company with no effect on plan assets. The Plan
believes the necessary modifications and replacement of computer systems will be
completed in a timely manner, and as a result, the year 2000 issue is not
expected to pose significant operational or financial problems for the Plan.

                                                                              28

                         Report of Independent Auditors

Administrative Committee
Jefferson Smurfit Corporation Retirement Plans

We have audited the accompanying statements of net assets available for plan
benefits of Smurfit Packaging Corporation Savings Plan as of December 31, 1998
and 1997, and the related statements of changes in net assets available for plan
benefits for the years then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits at December
31, 1998 and 1997, and the changes in its net assets available for plan benefits
for the years then ended, in conformity with generally accepted accounting
principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
held for investment as of December 31, 1998 and schedule of reportable
transactions for the year then ended are presented for purposes of complying
with the Department of Labor's Rules and Regulations for Reporting and
Disclosure under the Employee Retirement Income Security Act of 1974 and are not
a required part of the financial statements. The fund information in the
statements of net assets available for plan benefits and the statements of
changes in net assets available for plan benefits is presented for purposes of
additional analysis rather than to represent the net assets available for plan
benefits and changes in net assets available for plan benefits of each fund. The
supplemental schedules and fund information have been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, are fairly stated in all material respects in relation to the financial
statements taken as a whole.

                          Notes to Financial Statements

                                December 31, 1998


1. SIGNIFICANT ACCOUNTING POLICIES

The financial statements of the Smurfit Packaging Corporation Savings Plan (the
Plan) are reported on the accrual basis. The current values of investments have
been determined by T. Rowe Price as trustee for 1998 and 1997 and have been
based on closing prices if traded on national stock exchanges or bid prices for
bonds. The immediate participation contracts and participant loans are valued at
cost which approximates market. The differences between the current value and
the cost of investments are reflected in the statements of changes in net assets
available for plan benefits as part of net realized and unrealized appreciation
(depreciation) of investments. The cost of securities sold is based on the
weighted average method.

As of January 1, 1997, the Plan changed the Plan's trustee from Mercantile Bank
of St. Louis to T. Rowe Price. As of October 1, 1996, funds were transferred
into an omnibus account, and investment options were changed from the various
Arch funds to T. Rowe Price funds.

Administrative expenses are paid by the Plan. In 1997, the Plan changed the
allocation of administrative expenses to participant accounts from a prorated
method to allocating expenses to a participant's most stable fund.

The preparation of financial statements in conformity with generally accepted
accounting principles requires plan management to make estimates and assumptions
that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

2. DESCRIPTION OF THE PLAN

The Plan is a contributory employee benefit plan of Smurfit Packaging
Corporation (Company) and adopting subsidiaries and affiliates. The Plan is
composed of three components: (i) a cash or deferred compensation component
(401(k) component); (ii) an after-tax voluntary contribution component (ATC
component); and (iii) an employer matching contribution component.

The Plan is administered by an Administrative Committee (Committee) consisting
of officers or other employees of the Company or its adopting subsidiaries and
affiliates. The Committee prescribes forms for use by participants and may make
administrative and procedural recommendations.

Employees eligible to participate in the Plan generally consist of all employees
of the Company and adopting subsidiaries and affiliates, except for (1) those
employees covered by a collective bargaining agreement which provides for
retirement benefits, (2) nonresident aliens, and (3) substantially all hourly
employees.

Under the 401(k) provisions, employees may elect to have a portion of their
salary deferred and contributed to the Plan to be invested in one or more of 15
investment options available under the Plan. The participants' ATC contributions
are invested in an immediate participation contract or in one or more of 15
investment options available under the Plan in 1998 and 1997. Contributions are
made bimonthly.

Under the employer contribution provisions, each employer contributes, for each
of its employees who are participants, an amount equal to 65 percent of the
401(k) contributions authorized by such employee for 1998 and 1997,
respectively, to a maximum of $5,000 ($4,750 in 1997) in one calendar year, to
the extent the rate of such contributions, in effect from time to time, does not
exceed 3.9 percent in 1998 and 1997 of the participant's compensation (matching
contributions). The 401(k) contributions authorized by a participant in excess
of 6 percent of participant compensation for any pay period are disregarded for
purposes of matching contributions. Effective November 18, 1998, employer
contributions are invested in the same manner as the employee's election.

Participant contributions to the 401(k) plan which are made via payroll
withholdings are limited to the lesser of $10,000 and $9,500 or 15 percent of
participant compensation for calendar years 1998 and 1997. Participant
contributions to the ATC are limited to 15 percent of participant compensation,
not to exceed 20 percent of participant compensation in total when combined with
401(k) contributions. Total contributions credited to a participant's account
(combined 401(k), ATC, and matching contribution components) are limited to the
lesser of $30,000 or 25 percent of compensation. These limitations are
determined on a calendar year basis.


                                                                             25

2. DESCRIPTION OF THE PLAN (CONTINUED)

Terminated participants of the Plan are paid the current value of their 401(k)
account, their ATC account, and the vested portion of their employer match
account. Participants may elect a cash distribution or a stock distribution from
the SSCC Common Stock Fund or the Mobil Stock Fund. All other distributions are
in cash.

Each participant has a fully vested and nonforfeitable interest in the value of
his or her proportional share of the investment funds in which his or her 401(k)
contributions and ATC contributions are invested. Employer contributions vest
over a five-year period based on participant years of service. The nonvested
portion of a terminating participant's account constitutes a forfeiture and is
applied to reduce future employer contributions. If a participant, who has
forfeited all or a part of his or her account, is reemployed before 60 months
have elapsed after his or her employment ended, any amount he or she forfeited
will be restored to his or her account from amounts forfeited currently by other
participants.

Upon enrollment in the Plan, contributions may be directed into the following
funds by the participant or employer:

     SSCC Common Stock Fund - Effective August 1, 1994 and prior to November 18,
     1998, all employer contributions are invested in shares of Jefferson
     Smurfit Corporation (JSC) common stock. On November 18, 1998, JSC merged
     with Stone Container Corporation, and the company was renamed Smurfit-Stone
     Container Corporation (SSCC). Effective November 18, 1998, employer
     contributions are invested in the same manner as the employee's election.

     JS Group Stock Fund - Employer contributions prior to August 1, 1994 were
     invested in Jefferson Smurfit Group plc common stock. After August 1, 1994,
     dividends received by the JS Group Stock Fund were invested in shares of
     SSCC common stock and transferred to the SSCC Common Stock Fund.


                                                                             26

4. PLAN TAX STATUS

The Internal Revenue Service ruled on May 30, 1996 that the Plan qualifies under
Section 401(a) and meets the requirements under Section 401(k) of the Internal
Revenue Code (IRC), and therefore, the related trust is not subject to tax under
present income tax law. Once qualified, the Plan is required to operate in
conformity with the IRC to maintain its qualification. The Committee is not
aware of any course of action or series of events that has occurred that might
adversely affect the Plan's qualified status.

Participants are not subject to federal income tax on amounts contributed to
their 401(k) or employer matching contribution amounts under the Plan or on
earnings attributable to all contributions, until such time as these amounts are
distributed to or withdrawn by participants.

5. YEAR 2000 (UNAUDITED)

Computer programs which have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. Beginning in the year 2000,
this could result in a system failure or miscalculations causing disruptions of
operations, including a temporary inability to process transactions or engage in
normal business activities.

The Company has completed testing for its internal systems which impact the
processing of transactions on behalf of the Plan. The only major system related
to the Plan which is noncompliant is the payroll system, which is currently in
the process of being updated to a new year 2000-compliant system. The payroll
system and all other systems are expected to be year 2000-compliant by mid-1999.

The Plan has obtained formal communications from its service providers to
determine the extent to which the Plan's interface systems are vulnerable to
those third parties' failure to resolve their own year 2000 issues. The Plan's
review of these communications is expected to be complete by mid-1999.

Substantially all of the costs of the year 2000 inquiries and the systems
updates are being paid by the Company with no effect on plan assets. The Plan
believes the necessary modifications and replacement of computer systems will be
completed in a timely manner, and as a result, the year 2000 issue is not
expected to pose significant operational or financial problems for the Plan.

                         Report of Independent Auditors

Administrative Committee
Stone Container Corporation
   Deferred Income Savings Plan

We have audited the accompanying statement of net assets available for plan
benefits of the Stone Container Corporation Deferred Income Savings Plan as of
December 31, 1998 and the related statement of changes in net assets available
for plan benefits for the year then ended. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audit. Other auditors have
audited the financial statements of the Plan for the year ended December 31,
1997. Their report dated June 23, 1998 expressed an unqualified opinion on those
statements.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for plan benefits of the Plan at
December 31, 1998 and the changes in its net assets available for plan benefits
for the year then ended, in conformity with generally accepted accounting
principles.

Our audit was performed for the purpose of forming an opinion on the financial
statements taken as a whole. The fund information in the statements of net
assets available for plan benefits and the statements of changes in net assets
available for plan benefits is presented for purposes of additional analysis
rather than to represent the net assets available for plan benefits and changes
in net assets available for plan benefits of each fund. The fund information has
been subjected to the auditing procedures applied in our audit of the financial
statements and, in our opinion, is fairly stated in all material respects in
relation to the financial statements taken as a whole.

            Stone Container Corporation Deferred Income Savings Plan

                          Notes to Financial Statements

                                December 31, 1998


1. SIGNIFICANT ACCOUNTING POLICIES

The financial statements of the Stone Container Corporation Deferred Income
Savings Plan (the Plan) are reported on the accrual basis. The Plan participates
in the Stone Container Corporation Defined Contribution Master Trust (the Master
Trust). The financial statements of the Plan disclose only the Plan's allocated
share of the assets and the investment earnings and losses of the Master Trust
(see Note 4) by fund. During 1998 and 1997, the Master Trust included four other
defined contribution plans also sponsored by Stone Container Corporation (the
Company).

The value of investments of the Master Trust in mutual funds is determined by
Bankers Trust Company (the Trustee) based on prices reported by the issuing
registered investment company. Investment contracts and pooled investment funds
are valued at cost plus accrued interest, which approximates fair value. The
differences between the fair value and the cost of investment in the Master
Trust are reflected in the statements of changes in net assets available for
plan benefits as part of net investment income. The cost of securities is based
on the weighted average method.

Investment manager expenses for the fixed income fund are paid by the Plan. The
investment manager expenses for the fixed income fund for the years ended
December 31, 1998 and 1997, were $54,043 and $23,815, respectively. The majority
of other administrative expenses are paid by the Company.

The preparation of financial statements in conformity with generally accepted
accounting principles requires plan management to make estimates and assumptions
that affect the amounts reported in the financial statements and accompanying
notes. Actual results could differ from those estimates.

2. DESCRIPTION OF THE PLAN

The Plan is a contributory employee benefit plan of the Company and adopting
subsidiaries. On November 18, 1998, the Company merged with a wholly owned
subsidiary of Jefferson Smurfit Corporation (JSC) (the Merger). Upon
consummation of the Merger, JSC changed its name to Smurfit-Stone Container
Corporation (SSCC). The Company and Jefferson Smurfit (U.S.), a wholly owned
subsidiary of SSCC, approved the merger of the Plan with the Jefferson Smurfit
Corporation Savings Plan (the JSC Plan) effective July 1, 1999 (the Plan
Merger). As a result of the Plan Merger, the Plan will be amended to conform to
the JSC Plan, and existing plan participant balances will be transferred into
the JSC Plan.

                          Notes to Financial Statements (continued)


2. DESCRIPTION OF THE PLAN (CONTINUED)

The Plan is administered by a committee (the Committee) appointed by the Company
consisting of officers or other employees of the Company or its adopting
subsidiaries. The Committee prescribes forms for use by participants and may
make administrative and procedural recommendations.

Employees eligible to participate in the Plan generally consist of all employees
of the Company and its adopting subsidiaries, except for (1) those employees
covered by a collective bargaining agreement which provides for retirement
benefits, (2) nonresident aliens, and (3) substantially all hourly employees.

The Plan is composed of two components: (i) a cash or deferred compensation
component (401(k) component) and (ii) an employer matching contribution
component. Under the 401(k) provisions, employees may elect to have a portion of
their salary deferred and contributed to the Plan to be invested in one or more
of the investment options available under the Plan.

Under the employer contribution provisions, each employer contributes, for each
of its employees who are participants, an amount equal to 50 percent of the
401(k) contributions authorized by such employee up to a maximum of $4,000 in
one calendar year, to the extent the rate of such contributions, in effect from
time to time, does not exceed 2.5 percent of the participant's compensation
(matching contributions). The 401(k) contributions authorized by a participant
in excess of 5 percent of the participant's compensation for any period are
disregarded for purposes of matching contributions. Participants must be
employed on the last day of the plan year to qualify for the employer matching
contribution, except in the case of death, permanent disability, or retirement
during the plan year. However, the Plan was amended to allow participants
involuntarily terminated as a result of the Merger to qualify for the employer
matching contributions even though they were not employed as of the last day of
the plan year.

Participant contributions to the 401(k) plan which are made via payroll
withholdings are limited to the lesser of $10,000 and $9,500 for 1998 and 1997,
respectively, or 15 percent of participant compensation for the year.

Terminating participants of the Plan are paid the current value of their 401(k)
account and the vested portion of their employer match account. Participant
balances in the Company stock fund are distributable in shares of SSCC common
stock. All other distributions are made in a lump-sum cash distribution or, upon
request, in the form of an annuity.




                                                                              11

                          Notes to Financial Statements (continued)



2. DESCRIPTION OF THE PLAN (CONTINUED)

Each participant has a fully vested and nonforfeitable interest in the value of
his or her proportional share of the investment funds in which his or her 401(k)
contributions are invested. Effective January 1, 1997, participants become fully
vested in the 1997 and subsequent plan year employer matching contributions
after completion of five years of service from their date of hire.
Notwithstanding the foregoing, if as of March 2, 1997, participants have three
or more years of service from their date of hire, they are fully vested in their
December 31, 1996 account balance and all future employer matching
contributions. Prior to January 1, 1997, participants were fully vested, at all
times, in the Company's matching contributions and earnings thereon. The
nonvested portion of a terminating participant's account constitutes a
forfeiture and is applied to reduce future employer contributions.

Upon enrollment in the Plan, contributions may be directed into one of the
following funds by the participant or employer:

         Fixed Income Fund - Employee contributions are invested in fixed income
         contracts and pooled investment funds which provide for a specified
         rate of investment income for a specified period of time and under
         which the payment of principal is guaranteed.

         Equity Fund - Employee contributions are invested in the shares of
         mutual funds of registered investment companies which invest primarily
         in common stock.

         Money Market Fund - Employee contributions prior to December 31, 1989
         were invested in money market and deposit accounts for a specified
         period of time and under which the payment of principal is guaranteed.

         Company Stock Fund - Employee contributions and the employer matching
         contributions are invested solely in the common stock of SSCC.

         Balanced Fund - Employee contributions are invested in the shares of
         mutual funds of registered investment companies investing in common
         stock, preferred stock, and corporate and government bonds.



                                                                              12

                          Notes to Financial Statements (continued)



2. DESCRIPTION OF THE PLAN (CONTINUED)

         Small Company Growth Fund - Employee contributions are invested in the
         shares of mutual funds of registered investment companies which invest
         primarily in common stock of smaller capitalized companies. Employee
         contributions into this fund are limited to 25 percent of total
         employee contributions in any one year under the terms of the Plan.

         International Equity Fund - Employee contributions are invested in the
         shares of mutual funds of registered investment companies which invest
         primarily in the common stock of companies outside of the United
         States.

3. PLAN TAX STATUS

The Internal Revenue Service ruled January 27, 1999 that the Plan continues to
qualify under Section 401(a) and meets the requirements under Section 401(k) of
the Internal Revenue Code (IRC), and therefore, the Plan is not subject to tax
under present income tax law. However, the Plan has been amended since receiving
this determination letter. The Plan's administrator and the Plan's counsel
believe that the Plan is designed and is currently being operated in compliance
with the applicable requirements of the IRC.

Participants are not subject to federal income tax on amounts contributed to
their 401(k) or employer matching contribution accounts under the Plan or on
earnings attributable to such contributions until such time as these amounts are
distributed to or withdrawn by them.




                                                                              13

4. PARTICIPATION IN THE MASTER TRUST

At December 31, 1998 and 1997, the Plan's interest in the net assets of the

The Trustee computes the beneficial interest in the Master Trust for each
participating defined contribution plan on a monthly basis. The current month's
Master Trust investment transactions are allocated based on each plan's computed
share in the Master Trust at the end of the month, adjusted for the current
month's contributions less payments to beneficiaries and certain administrative
expenses. These allocated amounts are added to or subtracted from the prior
month's computed shares, as adjusted, to determine computed shares at the end of
the current month. Master Trust investment transactions allocated to the Plan
include dividend and interest income and net appreciation (depreciation) in the
fair value of investments. These amounts, net of allocated administrative
expenses, represent the Plan's share of investment income in the Master Trust
and are presented on the statements of changes in net assets available for plan
benefits.

disbursement, in accordance with generally accepted accounting principles. Under
the rules for preparation of its Form 5500, the Plan reflects an accrual for the
amount to be paid to participants who have withdrawn from the Plan prior to

6. TRANSFER OF ASSETS WITH OTHER PLANS

Effective January 1, 1997, employees of S&G Packaging, LLC and US Forest
Industries, Inc. who were formerly participants in the Plan were transferred to
the S&G Packaging, LLC Employee Retirement Savings Plan and the US Forest
Industries, Inc. Salaried 401(k) Savings Plan, respectively. The net assets of
the Plan relating to these participants were transferred to the respective
plan's trustees.

7. YEAR 2000 (UNAUDITED)

Computer programs which have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. Beginning in the year 2000,
this could result in a system failure or miscalculations causing disruptions of
operations, including a temporary inability to process transactions or engage in
normal business activities.

The Company has completed testing for its internal systems which impact the
processing of transactions on behalf of the Plan. The only major system related
to the Plan which is noncompliant is the payroll system, which is currently in
the process of being updated to a new year 2000-compliant system. The payroll
system and all other systems are expected to be year 2000-compliant by mid-1999.

The Plan has obtained formal communications from its service providers to
determine the extent to which the Plan's interface systems are vulnerable to
those third parties' failure to resolve their own year 2000 issues. The Plan's
review of these communications is expected to be complete by mid-1999.

Substantially all of the costs of the year 2000 inquiries and the systems
updates are being paid by the Company with no effect on plan assets. The Plan
believes the necessary modifications and replacement of computer systems will be
completed in a timely manner, and as a result, the year 2000 issue is not
expected to pose significant operational or financial problems for the Plan.
