                   HEALTHWORLD CORPORATION AND SUBSIDIARIES
                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                                March 31, 1998
                                  (UNAUDITED)

1.    ORGANIZATION AND BASIS OF PRESENTATION

         On November 12, 1997, Healthworld Corporation (the "Company")
         acquired (the "Consolidation"), in exchange for shares of its Common
         Stock, all of the issued and outstanding common stock of each of (i)
         Girgenti, Hughes, Butler & McDowell, Inc. and its affiliated entities
         ("GHB&M") and (ii) Milton Marketing Group Limited and its
         subsidiaries ("Milton"). Unless otherwise indicated, all references
         herein to the "Company" include GHB&M and Milton and give effect to
         the Consolidation. The Consolidation was accounted for under the
         pooling of interests method of accounting. Accordingly, the Company's
         consolidated financial statements and notes thereto have been
         restated to include the results of GHB&M and Milton for all periods
         presented.

         The Company is an international marketing and communications services
         company specializing in health care. The Company provides many of the
         world's largest pharmaceutical and other health care companies with a
         comprehensive range of integrated strategic marketing services
         designed to accelerate the market acceptance of new products and to
         sustain marketability throughout their life-cycles. The Company's
         services include advertising and promotion, contract sales,
         consulting, publishing, medical education, public relations,
         interactive multimedia, database marketing and marketing research
         services. The Company offers its clients global reach and expertise
         through its operations in the United States and the United Kingdom,
         and through Healthworld B.V., a world-wide network of licensed
         independent marketing and communications agencies located in 13 other
         countries, of which the Company is a founding licensee.

         The accompanying consolidated financial statements include the
         accounts of the Company and all of its subsidiaries. All intercompany
         balances and transactions have been eliminated in consolidation.

         Certain amounts in the financial statements for prior years have been
         reclassified to conform to the current year presentations for
         comparative purposes.

         The accompanying unaudited consolidated financial statements reflect
         all adjustments, consisting only of normal recurring accruals, which
         are, in the opinion of the Company's management, necessary to present
         fairly the financial position as of March 31, 1998 and the results of
         operations and cash flows for the interim periods ended March 31,
         1997 and 1998. Interim results are not necessarily indicative of
         results for a full year. For further information, refer to the
         consolidated financial statements and the accompanying footnotes

         included in the Company's annual report on form 10-K for the year
         ended December 31, 1997.

2.    NET INCOME PER COMMON SHARE

         Effective December 15, 1997, the Company adopted Statement of
         Financial Accounting Standards ("SFAS") No. 128, "Earnings Per Share"
         ("SFAS No. 128"). This statement establishes standards for computing
         and presenting Earnings Per Share ("EPS"), replacing the presentation
         of primary EPS with a presentation of basic EPS. For companies with
         complex capital structures, the statement requires dual presentation
         of both basic EPS and diluted EPS on the face of the statement of
         income. In accordance with SFAS No. 128, basic earnings per common
         share amounts were computed by dividing net earnings by the weighted
         average number of common shares outstanding, excluding any potential
         dilution. Diluted earnings per common share amounts were computed by
         reflecting potential dilution from the exercise of stock options.

         The following chart provides a reconciliation of information used in
         calculating the per share amounts, for the three month period ended
         March 31, 1998:

3.    INCOME TAXES

         Income taxes have been provided using the liability method in
         accordance with SFAS No. 109, "Accounting for Income Taxes." The
         provision for income taxes (recorded at an effective rate of 40.9%
         for the quarter ended March 31, 1998) reflects management's
         estimation of the effective tax rate expected to be applicable for
         the fiscal year. This estimate is evaluated by management each
         quarter based on estimated tax expenses for the year. Prior to the
         Consolidation, certain of the entities comprising GHB&M were treated

         as S Corporations and not subject to Federal corporate income taxes.
         Such entities were subject to certain corporate level state and local
         income taxes which are provided for in the quarter ended March
         31,1997.

4.    COMPREHENSIVE INCOME

         The Financial Accounting Standards Board issued SFAS No. 130,
         "Reporting Comprehensive Income", which establishes standards for
         reporting and display of comprehensive income and its components in a
         full set of general-purpose financial statements. This Statement is
         effective for fiscal years beginning after December 15, 1997,
         including interim periods.

                                      5

          Comprehensive income is as follows:

                                                     ===========  ==========

5.    NEW ACCOUNTING STANDARDS

         The Financial Accounting Standards Board issued SFAS No. 131,
         "Disclosures About Segments of an Enterprise and Related Information"
         ("SFAS No. 131"), which establishes standards for the way that public
         business enterprises report information about operating segments in
         financial statements issued to shareholders. It also establishes
         standards for related disclosures about products and services,
         geographic areas, and major customers. SFAS No. 131 is effective for

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


         This March 31, 1998 Quarterly Report on Form 10-Q contains statements
         which constitute forward-looking statements within the meaning of
         Section 27A of the Securities Act of 1933, as amended, and Section
         21E of the Securities Exchange Act of 1934, as amended. Those
         statements include statements regarding the intent, belief or current
         expectations of the Company and its management team. The Company's
         stockholders and prospective investors are cautioned that any such
         forward-looking statements are not guarantees of future performance
         and involve risks and uncertainties, and that actual results may
         differ materially from those projected in the forward-looking
         statements. Such risks and uncertainties include, among other things,
         competitive, economic and regulatory factors in the health care
         marketing and communications industry and the pharmaceutical and
         health care industry, general economic conditions, the ability of the
         Company to manage its growth and successfully implement its business
         strategy and other risks and uncertainties that are discussed herein.

         The following discussion should be read in conjunction with the
         attached unaudited consolidated financial statements and notes
         thereto and with the Company's audited financial statements, notes to
         the consolidated financial statements and Management's Discussion and
         Analysis of Financial Condition and Results of Operations relating
         thereto included or incorporated by reference in the Company's Annual
         Report on Form 10-K for the fiscal year ended December 31, 1997.

         Results of Operations

         Fiscal Three Months Ended March 31, 1998 Compared to Fiscal Three 
         Months Ended March 31, 1997

         Revenues

         Revenues for the first three months of 1998 were $14.0 million, an
         increase of $7.7 million, or 122.8%, from $6.3 million for the first
         three months of 1997. Contract sales revenues increased to $8.5
         million, an increase of 280.7% from $2.3 million in the prior year's
         quarter. This was attributable to the growth of the contract sales
         operation in the United Kingdom, which resulted primarily from
         additional business from new clients. Communications revenue for the
         quarter ended March 31, 1998 increased to $5.5 million, an increase
         of 35.1% from $4.0 million in the first quarter of 1997.
         Approximately $1.0 million was attributable to the growth of
         advertising and promotion services, which resulted primarily from new
         projects from existing clients.

         Salaries and Related Costs

         Salaries and related costs for the first three months of 1998 were
         $11.5 million, an increase of $6.8 million, or 143.0%, from $4.7
         million for the first three months of 1997. Salaries and related
         costs include all compensation and related benefits for all employees
         and contracted talent. Such increase was primarily attributable to
         (i) $5.1 million of labor and


                                      7
<PAGE>

         other direct costs relating to the growth of the Company's contract
         sales operations, (ii) approximately $500,000 relating to the
         additional support staff hired to handle the increased level of
         contract sales business activity, and salaries related to the
         start-up of the U.S. contract sales division, and (iii) approximately
         $900,000 relating to staffing costs attributable to communications
         services. Salaries and related costs represented 82.5% of revenues in
         the first three months of 1998, compared to 75.6% in the first three
         months of 1997. Such increase, as a percentage of revenues, was
         primarily attributable to growth of the Company's contract sales
         operations and the corresponding increase in labor costs and
         increased staffing costs for such operations. Generally, labor costs
         associated with contract sales operations are greater as a percentage
         of corresponding revenues than those for the Company's other
         services.

         Other Operating Expenses

         Other operating expenses for the first three months of 1998 were $2.1
         million, an increase of $809,000, or 61.6%, from $1.3 million for the
         first three months of 1997. Other operating expenses primarily
         include occupancy and related costs, client development and other
         related administrative costs. Such increase includes increased
         spending to support (i) increased occupancy and related costs of
         approximately $218,000 as a result of increased rent and occupancy
         related costs, (ii) increased business development costs of $422,000,
         and (iii) increased professional costs of $127,000 relating to the
         transition of the Company from being a private to a public company.
         Other operating expenses represented 15.2% of revenues in the first
         three months of 1998, compared to 20.9% of the revenues in the first
         three months of 1997. The decrease in other operating expenses, as a
         percentage of revenues, was primarily attributable to such expenses
         generally being fixed relative to increases in the Company's
         revenues.

         Income From Operations

         Income from operations for the first three months of 1998 was
         $324,000, an increase of $108,000 or 50.0%, from $216,000 for the
         first three months of 1997. Income from operations represented 2.3%
         of revenues in the first three months of 1998, compared to 3.4% in
         the first three months of 1997.

         Interest Income

         Interest income, net, in the first three months of 1998 was $190,000,
         an increase of $170,000 or 850% from $20,000 for the first three
         months of 1997, primarily due to higher cash and cash equivalents for
         the first three months of 1998. Such increase was attributable to the
         receipt of the net proceeds from the Company's initial public
         offering ("IPO") of common stock which was consummated in November

         1997.

         Provision for Income Taxes

         The provision for income taxes for the first three months of 1998 was
         $210,000, an increase of $205,000 from $5,000 for the first three
         months of 1997. Such increase was primarily attributable to the
         Company being taxed as a C corporation for the first three months of
         1998. During the first three months of 1997, certain of the companies
         comprising GHB&M were treated as S Corporations, pursuant to which
         income or loss of each of such companies was allocated to its
         stockholders by inclusion in their respective individual income tax
         returns.

         Net Income

         Net Income for the first three months of 1998 was $304,000, an
         increase of $113,000 or 59.2% from $191,000 for the first three
         months of 1997. This was primarily attributable to the earnings from
         operations relating to the $6.3 million increased sales in contract
         sales and the increase in interest income relating to the increased
         cash and cash equivalents from the IPO, offset by the increase in the
         provision for income taxes which was not provided for in the first
         three months of 1997. Net Income represented 2.2% of revenues in the
         first three months of 1998 compared to 3.0% in the first three months
         of 1997.

         Liquidity and Capital Resources

         At March 31, 1998 and December 31, 1997, the Company had cash and
         cash equivalents of approximately $16.7 million and $18.1 million,
         respectively, a decrease of $1.4 million. The decrease in cash and
         cash equivalents was commensurate with the growth in the business
         during the quarter ended March 31, 1998. The Company's working
         capital was $19.4 million and $19.0 million at March 31, 1998 and
         December 31, 1997, respectively. The increase in working capital is
         primarily attributable to the Company's income from operations of
         approximately $324,000.

         Bank borrowings for the Company's U.S. operations from Chase
         Manhattan Bank , N.A. (the "GHB&M Credit Facility") consist of (i) an
         uncommitted line of credit (the "GHB&M Line of Credit") which expires
         on June 30, 1998 and bears interest at the bank's prime rate (8.5% as
         of March 31, 1998) plus 1.0% per annum, pursuant to which GHB&M may
         request borrowings of, but the bank is not obligated to lend, up to
         $3.5 million, (ii) a term note in the principle amount of $300,000
         (the "GHB&M Term Note"), and (iii) a letter of credit in the amount
         of $200,000 (the "GHB&M Letter of Credit"). The GHB&M Credit Facility
         is secured by a first security interest in GHB&M's personal property
         and is personally guaranteed by certain of GHB&M's stockholders. The

         GHB&M Term Note had $100,000 outstanding as of March 31, 1998 and
         bears interest at 7.75% per annum and is payable in 36 equal monthly
         installments with the last installment due February 1999. No amounts
         were outstanding under the GHB&M Line of Credit as of March 31, 1998.

         Borrowings for the Company's U.K. operations consist of an overdraft
         facility (the "Milton Overdraft Facility") with Bank of Scotland for
         an aggregate amount of up to $1.25million. Amounts drawn under the
         Milton Overdraft Facility bear interest payable at the United

                                      9
<PAGE>
 
         Kingdom base rate (7.25% as of March 31, 1998) plus 2.0% per annum
         (the "Prevailing Rate"). As of March 31, 1998, Milton had an
         outstanding balance of approximately $203,000 under the facility. In
         addition, as of March 31, 1998, the Company had the following
         outstanding indebtedness with respect to its U.K. operations: (i) a
         term loan from Bank of Scotland (the "Milton Term Loan") in the
         principle amount of $588,000 (of which $351,000 was outstanding on
         March 31, 1998) which bears interest payable at the Prevailing Rate
         with principle payable in installments of $58,000 each May and
         November through November 2000; (ii) a term loan in the principle
         amount of $460,000 (all of which was outstanding on March 31,1998),
         which bears interest at the rate of 4% per annum, under which
         principle is due and payable in July 1998: and (iii) a term loan from
         National Westminster Bank plc in the principle amount of $75,000
         ($3,000 of which was outstanding as of March 31,1998, which bears
         interest at 10.5% per annum payable in monthly installments, with the
         final payment due in April 1998.

PART II

Item 2.   Changes in Securities and Use of proceeds

          On November 21, 1997, the Company commenced an IPO of 2,415,000
         shares of its Common Stock, par value $.01 per share. The Company's
         registration statement on form S-1 (File No. 333-34571) filed with
         the Securities and Exchange Commission (the "Commission") with
         respect to the IPO was declared effective by the Commission on
         November 21, 1997. All of the shares of the Common Stock included in

         The aggregate net proceeds received by the Company from the Offering,
         after deducting underwriting discounts and commissions and expenses,
         was approximately $16,445,000. Through December 31, 1997, the Company
