                          THE STUDENT LOAN CORPORATION

                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
                                  JUNE 30, 1999



1.    SIGNIFICANT ACCOUNTING POLICIES

      INTERIM FINANCIAL INFORMATION

      The financial information of The Student Loan Corporation (the "Company")
      as of June 30, 1999 and for the three and six-month periods ended June 30,
      1999 and 1998 includes all adjustments (consisting of normal recurring
      adjustments) which, in the opinion of management, are necessary to fairly
      state the Company's financial position and results of operations in
      conformity with generally accepted accounting principles ("GAAP"). The
      accompanying financial statements should be read in conjunction with the
      financial statements and related notes included in the Company's 1998
      Annual Report and Form 10-K.

2.    USE OF ESTIMATES

      In preparing the financial statements in conformity with GAAP, management
      has used a number of estimates and assumptions relating to the reporting
      of assets and liabilities, the disclosure of contingent assets and
      liabilities and the reported amounts of revenues and expenses during the
      reporting period. Actual results could differ from those estimates and
      assumptions.

3.    COMMITMENTS AND CONTINGENCIES

      REGULATORY IMPACTS

      The Company's loan portfolio is primarily comprised of loans originated
      under the Federal Family Education Loan ("FFEL") program. Since 1992, a
      series of amendments to the Higher Education Act of 1965 (the "Act"),
      which governs the FFEL program, have increased costs and reduced interest
      payments to lenders. These legislative changes have progressively reduced
      the net interest margin of the Company's portfolio.

      The 1993 amendments to the Act also introduced a competitor program, the
      Federal Direct Student Loan program ("direct lending"), in which private
      lenders such as the Company do not participate. Direct lending currently
      accounts for approximately one-third of the student loans originated under
      federally sponsored programs.

4.    RESTRUCTURING PLAN

      In the fourth quarter of 1997, the Company announced a restructuring plan
      to realign its business and processing structure. The restructuring plan
      included the outsourcing of various parts of the Company's operations,
      which had been based in the Company's Pittsford, New York office, to
      affiliated companies. The restructuring plan was designed to take
      advantage of the larger economies of scale and more global operating
      systems configurations being employed by those affiliates. The Company
      expects to retain


                                       6
<PAGE>   7


      approximately 200 Pittsford-based employees, primarily in the technology
      and accounting functions, and employ approximately 100 employees in
      administration, finance, marketing, sales and other activities in
      Stamford, Connecticut and in field locations throughout the United States.

      In connection with the restructuring plan, the Company recorded a $20.5
      million pre-tax charge in the fourth quarter of 1997, including $16.2
      million relating to estimated severance benefits, $2.8 million relating to
      furniture and equipment write-downs and $1.5 million relating to other
      estimated exit costs. Additional costs, including $4.0 million of
      transition costs incurred in the first half of 1999 (of which $0.7 million
      was incurred in the second quarter), did not qualify for recognition in
      the initial $20.5 million charge and were expensed as incurred.

      Of the $20.5 million restructuring reserve, $17.4 million has been used
      through June 30, 1999, including $3.1 million used during the second
      quarter of 1999. Of the $3.1 million, severance and outplacement costs
      were $1.6 million and the remaining $1.5 million represents a reserve
      release that was offset to operating expenses. The total overall $17.4
      million usage includes $2.8 million in furniture and equipment
      write-downs, $4.2 million in severance and outplacement costs paid to the
      approximately 380 employees on job discontinuance, $1.4 million in other
      exit costs, and $9.0 million in reserve releases. The Company's
      restructuring plan is substantially complete at this time with
      approximately half of the $3.1 million reserve balance at June 30, 1999
      designated for the approximately 120 terminated employees still receiving
      severance benefits. The remainder of the reserve will be used for the
      estimated 35 employees yet to be placed on job discontinuance.
      Approximately 20 staff reductions were made in the second quarter of 1999,
      bringing the 1999 year-to-date total to 180.

      The expectations of the Company relating to the restructuring plan are
      forward-looking statements within the meaning of the Private Securities
      Litigation Reform Act. See "Forward-Looking Statements" on page 9.

5.    RELATED PARTY TRANSACTIONS

      Citibank (New York State) ("CNYS"), a wholly-owned subsidiary of Citicorp
      and Citigroup Inc., owns 80% of the outstanding common stock of the
      Company. A number of significant transactions are carried out between the
      Company on the one hand and Citigroup Inc. and its affiliates on the other
      hand. At June 30, 1999, the Company had outstanding short-term and
      long-term borrowings with CNYS of $4.1 billion and $4.6 billion,
      respectively, compared to $3.9 billion and $4.3 billion, respectively, at
      December 31, 1998. For the three and six-month periods ended June 30,
      1999, the Company incurred $116.6 million and $231.5 million,
      respectively, in interest expense payable to CNYS and its affiliates,
      compared to $113.6 million and $225.1 million, respectively, in interest
      expenses payable to CNYS and its affiliates for the same periods in 1998.
      In addition, Citigroup Inc. and its subsidiaries engage in other
      transactions and servicing activities with the Company, including cash
      management, data processing, income tax payments, loan servicing, employee
      benefits and facilities management. Management believes that the terms of
      these transactions are, in the aggregate, no less favorable to the Company
      than those which could be obtained from unaffiliated parties.

6.    INTEREST RATE SWAP AGREEMENTS

      The Company, from time to time, enters into interest rate swap agreements
      with related and third parties solely to hedge interest rate exposure on
      certain interest bearing liabilities. The swap agreements are intended to
      reduce the risk caused by differences between borrowing and lending rates.
      Entering into swap agreements to pay interest based on the interest rate
      characteristics of the Company's assets and to receive interest based on
      the characteristics of the Company's liabilities effectively limits the
      risk of potential interest rate variability. The counterparty for most of
      the interest rate swap agreements outstanding at June 30, 1999 was
      Citibank, N.A., an affiliate of CNYS.

      Interest rate swap agreements with a net carrying value of $2.1 million,
      representing accrued interest receivable, were determined to have an
      estimated fair value of $2.1 million receivable at June 30, 1999. At
      December 31, 1998, interest rate swap agreements with a carrying value of
      $0.2 million of interest receivable had an estimated fair value of $3.4
      million receivable. The fair values were based on approximate values
      obtained from Citibank, N.A., the Company's dealer in these financial
      instruments, and represent the estimated amounts which would be receivable
      upon termination of the agreements. Fair values vary from period to period
      based on changes in such factors as LIBOR and Treasury Bill interest rates
      and the timing of contractual settlements. The aggregate notional
      principal amounts of swap agreements outstanding at June 30, 1999 and
      December 31, 1998 were $4.8 billion and $6.4 billion, respectively. For
      the second quarter of 1999, the Company recorded a $2.1 million ($3.1
      million year-to-date) reduction of interest expense related to interest
      accrued on its swap agreements. The Company recorded $0.8 million ($1.0
      million year-to-date) in additional interest expense related to its swaps
      during the second quarter of 1998.

7.    SHORT AND LONG-TERM BORROWINGS

      In the first six months of 1999, short-term debt increased by $0.25
      billion to $4.1 billion and $0.01 billion was repaid. Also, long-term
      borrowings increased by $0.26 billion to $4.6 billion and none was repaid
      during the first half of 1999.


8.    IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

      In June 1999, the Financial Accounting Standards Board ("FASB") deferred
      the effective date of Statement of Financial Accounting Standards ("SFAS")
      No. 133, "Accounting for Derivative Instruments and Hedging Activities"
      for one year. As a result, SFAS No. 133 will become effective on January
      1, 2001 for calendar year companies such as the Company.

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

FORWARD-LOOKING STATEMENTS

Certain statements contained in this report that are not historical facts are
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act. The Student Loan Corporation's (the "Company's") actual
results may differ materially from those suggested by the forward-looking
statements, which are typically identified by the words or phrases "believe,"
"expect," "anticipate," "intend", "estimate," "may increase," "may result in,"
and similar expressions or future or conditional verbs such as "will", "should",
"would" and "could". These forward-looking statements involve risks and
uncertainties including, but not limited to, the following: the effects of
future legislative changes; actual credit losses experienced by the Company in
future periods compared to the estimates used in calculating reserves;
fluctuations in the interest rates paid by the Company for its funding and
received on its loan portfolio and the success of the Company's hedging
policies; the ability of the Company and third party vendors to modify computer
systems for the year 2000 date conversion in a timely manner; the ability of the
Company generally to achieve anticipated levels of cost-savings relating to its
restructuring plan; as well as general economic conditions, including the
performance of financial markets and the passage of regulatory changes.

RESTRUCTURING PLAN

In the fourth quarter of 1997, the Company announced a restructuring plan to
realign its business and processing structure. The restructuring plan included
the outsourcing of various parts of the Company's operations, which had been
based in the Company's Pittsford, New York office, to affiliated companies. The
restructuring plan was designed to take advantage of the larger economies of
scale and more global operating systems configurations being employed by those
affiliates. The Company expects to retain approximately 200 Pittsford-based
employees, primarily in the technology and accounting functions, and employ
approximately 100 employees in administration, finance, marketing, sales and
other activities in Stamford, Connecticut and in field locations throughout the
United States.

In connection with the restructuring plan, the Company recorded a $20.5 million
pre-tax charge in the fourth quarter of 1997, including $16.2 million relating
to estimated severance benefits, $2.8 million relating to furniture and
equipment write-downs and $1.5 million relating to other estimated exit costs.
Additional costs, including $4.0 million of transition costs incurred in the
first half of 1999 (of which $0.7 million was incurred in the second quarter),
did not qualify for recognition in the initial $20.5 million charge and were
expensed as incurred.

Of the $20.5 million restructuring reserve, $17.4 million has been used through
June 30, 1999, including $3.1 million used during the second quarter of 1999. Of
the $3.1 million, severance and outplacement costs were $1.6 million and the
remaining $1.5 million represents a reserve release that was offset to operating
expenses. The total overall $17.4 million usage includes $2.8 million in
furniture and equipment write-downs, $4.2 million in severance and outplacement
costs paid to the approximately 380 employees on job discontinuance, $1.4
million in other exit costs, and $9.0 million in reserve releases. The Company's
restructuring plan is substantially complete at this time with approximately
half of the $3.1 million reserve balance at June 30, 1999 designated for the
approximately 120 terminated employees still receiving severance benefits. The
remainder of the reserve will be used for the estimated 35 employees yet to be
placed on job

discontinuance. Approximately 20 staff reductions were made in the second
quarter of 1999, bringing the 1999 year-to-date total to 180.

The expectations of the Company relating to the restructuring plan are
forward-looking statements within the meaning of the Private Securities
Litigation Reform Act. See "Forward-Looking Statements" on page 9.

FINANCIAL CONDITION

During the six months ended June 30, 1999, the net insured student loan
portfolio of the Company grew by $471.9 million (5%) from the balance at
December 31, 1998. This growth was the result of loan disbursements totaling
$919.6 million and loan purchases of $308.1 million in the first six months of
1999, partially offset by $179.6 million in loan sales and $569.8 million in
loan reductions (attributable to repayments and claims paid by guarantors), and
other adjustments of $6.4 million. This compares to loan disbursements of $846.1
million, loan purchases of $48.7 million, loan reductions of $488.6 million,
loan sales of $33.8 million, and other adjustments of $4.4 million in the first
six months of 1998. CitiAssist loan purchases have increased significantly for
the first half of 1999 compared to the same period in 1998 primarily due to
greater CNYS CitiAssist originations. The increase in loan sales for the first
half of 1999 compared to the same period last year is primarily due to increases
in the volume of the federal direct student loan consolidation program.

The Company's loan disbursements and CitiAssist loan commitments for the first
half of 1999 of $1,027.0 million were $120.7 million (13%) more than those made
in the same period of 1998. This increase is attributable primarily to large
increases in CitiAssist loan commitments and Federal Family Education Loan
("FFEL") program disbursements. During the first six months of 1999 CitiAssist
loan commitments increased to $107.4 million, a $47.1 million (78%) increase
from the same period last year. FFEL program disbursements of $775.6 million in
the first six months of 1999 is 7% higher than the $726.4 million disbursed
during the same period of 1998. This $49.2 million increase in FFEL program
disbursements does not include originations made under the Federal Loan
Consolidation program. Consolidation loan originations of $144.0 million for the
first two quarters of 1999 have increased $24.4 million (20%) compared to the
same period of 1998.

During the first two quarters of 1999, the Company made $233.5 million in
interest payments, principally to CNYS or one of its affiliates, compared to
$214.5 million for the same period in 1998. The difference is due to changes in
both the size of the borrowings and interest rates, as well as timing of
interest payments. The Company paid $14.1 million in income taxes during the
first two quarters of 1999, compared to $20.1 million for the same period last
year. The difference in the amount of taxes paid is primarily due to a timing
difference in making intercompany tax payments, and does not reflect any
significant changes in applicable income tax rates.

Other assets increased $32.5 million (14%) from December 31, 1998, principally
as a result of additional interest receivable attributable to growth in the
student loan portfolio and timing of interest receipts.

In the first six months of 1999, short-term debt increased by $0.25 billion and
$0.01 billion was repaid. Also, long-term borrowings increased by $0.26 billion
and none was repaid during the first six months of 1999.


                                       10
<PAGE>   11


The Company paid a quarterly dividend of $0.45 per common share on June 1, 1999.
The Board of Directors declared an increase in the quarterly dividend on the
Company's common stock to $0.60 per share to be paid on September 1, 1999 to
stockholders of record on August 13, 1999.

MARKET RISK

The Company's primary market risk exposure is to movements in U.S. dollar
interest rates. The Company manages interest rate risk exposure through the use
of derivative instruments in the form of interest rate swap agreements in order
to better match the interest rate characteristics of its liabilities with that
of its assets. Under these agreements, the Company pays interest based on the
interest rate characteristics of the Company's assets and receives interest
based on the characteristics of its liabilities. All of the Company's derivative
agreements terminate within a year and none are used for trading purposes.

Market risk is measured using various tools, including Earnings-at-Risk which
reflects repricing gaps in the position embedded in the portfolio. The Company
prepares Earnings-at-Risk calculations to measure the discounted pre-tax
earnings impact of a two standard deviation shift in a short-term interest rate
over the four-week period required to defease the position. As of June 30, 1999
the rate shift over the defeasance period applied to the interest yield curve

The Earnings-at-risk calculation is one measure of analyzing exposures based
upon the Company's positions at particular points in time. The Company, through
its Asset/Liability Management Committee, actively manages these risks and sets
Earnings-at-Risk limits to take appropriate actions if interest rates move
against the existing structure.

YEAR 2000

The arrival of the year 2000 poses a unique worldwide challenge to the ability
of time-sensitive computer systems to correctly interpret dates in the year 2000
and beyond. The Company has assessed and has substantially completed
modifications to its computer systems and business processes to provide for
their continuing functionality and is also assessing the readiness of third
parties with which it interfaces.

The Company is highly dependent on computer systems and system applications for
conducting its ongoing business functions. The inability of systems to recognize
properly the year 2000 could result in major systems failure or miscalculations
that would disrupt the Company's ability to meet its customer and other
obligations on a timely basis, and the Company has engaged in a process of
identifying, assessing, and modifying its computer programs to address this
issue. As part of year 2000 compliance work, systems are subjected to a
validation process that tests modified programs before they can be used in
production.

The pre-tax cost associated with all of the required modifications and
conversions is expected to total approximately $5.1 million through 1999, funded
through a combination of a reprioritization


                                       11
<PAGE>   12


of technology development initiatives and incremental costs and is being
expensed as incurred. Of the total, approximately $4.2 million had been incurred
through June 30, 1999, including $1.0 million for the first six months of 1999
(of which approximately $0.5 million was incurred in the second quarter).

Substantially all of the required modification and internal testing work has
been completed, including modification of all critical systems, and the Company
continues to make satisfactory progress towards full completion of its year 2000
program. The remainder of 1999 will be spent primarily addressing completion of
the remaining external testing, integration testing, and production assurance.

The Company's year 2000 program is also addressing other issues, including
replacement of certain business applications and compliance of end-user
computing applications, networks, data center, desktops, facilities, business
processes, and external providers. Substantially all of the investigation and
necessary remediation of these matters has been completed and substantially all
are considered compliant.

The Company is also addressing year 2000 issues that may exist with other
significant third parties with which it interfaces, including customers and
counterparties and its utility infrastructure. Unreadiness by these parties
would expose the Company to the potential for loss and impairment of business
processes and activities. While these parties are generally engaged in efforts
intended to address and resolve their year 2000 issues on a timely basis, it is
possible that a series of failures by third parties could have a material
adverse effect on the Company's results of operations in future periods.

The Company is completing contingency plans intended to address perceived risks
associated with its year 2000 effort. These activities include business
resumption planning to address the possibility of systems failure, and market
resumption planning to address the possibility of the failure of systems or
processes outside the Company's control. Contingency planning and preparations
for the management of the date change will continue through 1999.
Notwithstanding these activities, the failure of efforts to address, in a timely
manner, the year 2000 issue, could have a material adverse effect on the
Company's results of operations in future periods.

The expectations of the Company with respect to remediation  of year 2000
issues constitute  forward-looking statements within the meaning of the
Private Securities Litigation Reform Act.  See "Forward-Looking Statements"
on page 9.

RESULTS OF OPERATIONS

Quarter Ended June 30, 1999

Net income was $22.6 million ($1.13 basic and diluted earnings per share) for
the second quarter of 1999. This was an increase of $5.2 million (30%) from
earnings for the same period last year. The increase in net income was primarily
attributable to higher interest income generated by a $1.1 billion increase in
the loan portfolio from the same quarter last year and better spreads between
the Company's lending and borrowing interest rates. Contributing to the increase
in net income was a $0.9 million ($1.5 million pre-tax) release of the
restructuring reserve, which was booked as an offset to operating expenses in
the second quarter of 1999. On a comparable basis, net income grew by 25% after
adjusting second quarter 1999 income for the restructuring reserve release.


                                       12
<PAGE>   13


The net interest margin for the second quarter of 1999 was 2.57%, 0.10% higher
than the 2.47% margin for the second quarter of 1998. The improvement in the
margin for the second quarter of 1999 was primarily attributable to lower
funding rates, partially offset by the impact of previously legislated lender
yield reductions on FFELP loans, effective for loans originated on or after July
1, 1998. However, for the remainder of 1999, management expects interest margins
to decrease, as variable-funding arrangements will begin to reflect current,
less attractive market rates.

Total operating expenses for the second quarter of 1999 decreased $0.6 million
(3%) from the same period last year, attributable to reductions in salary and
employee benefit costs related to the restructuring. Also, operating expenses as
a percentage of average insured student loans improved 0.13% to 0.81% from the
second quarter of 1998 expense ratio of 0.94%. The improvement in the expense
ratio is primarily attributable to efficiencies in operational and
administrative expenses.

Return on equity was 18.6% for the second quarter of 1999, 2.1% higher than the
16.5% return for the same period of 1998. The increase was attributed to higher
1999 earnings.

The provision for loan losses was $0.4 million higher for the second quarter of
1999, compared to that recorded for the same period last year. This increase
reflects the risk sharing loss estimates on greater potential future default
claims resulting from growth in the portion of the portfolio that is subject to
the 2% risk sharing provisions of the Federal Higher Education Act of 1965 ("the
Act"), as amended.


Six Months Ended June 30, 1999

The Company earned net income of $45.8 million ($2.29 basic earnings per share)
for the six months ended June 30, 1999, an increase of $11.5 million (34%) from
the first half of 1998. The increase was primarily due to higher interest income
resulting from an increased loan portfolio and better interest rate spreads
between lending and borrowing rates.

Total operating expenses for the first half of 1999 were $35.5 million,
unchanged from the same period last year, as decreases in salary costs resulting
from the restructuring were offset by increased external loan servicing costs.
Operating expenses as a percentage of average insured student loans for the
first half of 1999 decreased to 0.80%, an improvement of 0.10% compared to the
first half of 1998, primarily attributable to efficiencies in administrative and
operational expenses.

The provision for loan losses was $2.1 million, $0.4 million (23%) higher for
the first six months of 1999 than that reported for the same period last year.
The increase reflects the risk sharing loss estimates on greater potential
future default claims as a result of growth in the portion of the portfolio that
is subject to the 2% risk sharing provisions of the Omnibus Budget
Reconciliation Act of 1993.

The Company's effective tax rate was approximately 41.7% for the first six
months of 1999, compared to 41.0% for the same period in 1998.

REGULATORY IMPACTS

The Company's loan portfolio is primarily comprised of loans originated under
the FFEL program. Since 1992, a series of amendments to the Act, which governs
the FFEL program, has increased costs and reduced interest payments to lenders.
These legislative changes have progressively reduced the net interest margin of
the Company's portfolio.

The 1993 amendments to the Act also introduced a competitor program, the Federal
Direct Student Loan program ("direct lending"), in which private lenders such as
the Company do not participate. Direct lending currently accounts for
approximately one-third of the student loans originated under federally
sponsored programs, approximately the same as the prior two years.

Since 1994, the Company has aggressively pursued both new and existing marketing
programs, expanded its guarantor relationships and sought new ways to meet the
education finance needs of schools and students, including the implementation of
loan programs, such as the Company's CitiAssist product, that are not dependent
on Federal funding, guarantees and authorization.
