PARTIES TO THE MERGER NDC. NDC is a Delaware corporation that was incorporated in 1967. NDC is a leading provider of high-volume information services and application systems to the health care and payment systems markets. NDC serves a diverse customer base comprised of almost 120,000 health care providers, 3,500 health care plans, more than 750,000 merchant locations, 35,000 corporations and 400 banking institutions, as well as federal and state government agencies. NDC markets its services directly to merchants and health care providers and indirectly through business alliances with a wide range of banks, insurance companies and distributors. NDC is one of the largest independent providers of health care information services and integrated payment systems and services in the United States, processing transactions at an annualized rate of approximately 3 billion at the end of fiscal 1997. NDC provides electronic claims processing and adjudication services, practice management systems, electronic data interchange ("EDI") services, billing services, business office management services and clinical data base information for pharmacies, dentists, physicians, hospitals, health maintenance organizations, managed care companies, clinics and nursing homes, as well as other health care providers. Management believes that NDC is the largest independent processor of real-time health care transactions in the country, and that it is well positioned to capitalize on the growing demand for cost containment and improved patient care in the health care industry. By the end of fiscal 1997, approximately 41% of NDC's total revenue was derived from NDC's health care systems and services, which represent the fastest growing portion of NDC's business. NDC's Global Payment Systems LLC subsidiary ("Global Payment Systems" or "Global") offers such services as authorization, equipment deployment, customer support, back office processing, merchant accounting and card issuing services on an outsourcing basis for banks and other participants in the payment systems industry. Global also offers information reporting and EDI services, cash management systems and services and electronic tax filing and payment services to government and corporate customers. In recent years, NDC has expanded the range of payment instruments services offered and distribution channels. NDC recently introduced a purchase card processing program that provides electronic payment capabilities for business-to-business purchasing transactions. Approximately 29% of NDC's total revenue for fiscal 1997 was derived from Global. The Integrated Payment Systems business unit provides a broad range of payment acceptance services primarily in partnership with banks. Under its Bank Alliance Program, as well as through other distribution channels, it adds sales, marketing and risk management services to the range of services provided by Global Payment Systems. NDC's Integrated Payment Systems unit accounted for approximately 30% of NDC's total revenue for fiscal 1997. 6 For the year ended May 31, 1997, NDC reported total revenues of $433.9 million, and net income of $38.8 million. As of May 31, 1997, NDC had total consolidated assets of $521.7 million and consolidated stockholders' equity of $277.5 million. NDC's principal executive offices are located at National Data Plaza, Atlanta, Georgia 30329-2010, and its telephone number is (404) 728-2000. For additional information regarding NDC and its business, see "Available Information," "Incorporation of Certain Information by Reference" and "-- Selected Financial Data." Source. Source is a leading provider of proprietary health care information, technology and consulting services, primarily to the pharmaceutical and retail pharmacy markets. Source's services enable clients to better understand individual prescriber, payer, consumer, pharmaceutical manufacturer, pharmacy benefit manager and retail pharmacy behavior in order to compete more effectively in the market place. Source typically enters into significant, long-term relationships with its clients, providing integrated services to executives in the sales, marketing, market research and information technology areas of these organizations. Source provides a broad array of information, data mining and integrated marketing decision-making tools. The Source database is a repository of intelligence on managed care organizations, prescribers, retailers, prescriptions and non-personalized patient data. The principal database (the "Alpha Database") contains information on 1.6 billion prescriptions dispensed by retail and mail order pharmacies over the previous 12 months. Over 90% of the prescriptions in the Alpha Database are matched to over 1,000,000 prescribers, linking them at the individual script level. Source jointly exploits its databases in an operating venture with Pharmaceutical Marketing Services Inc. ("PMSI"). Simultaneously with the consummation of the Merger, NDC will acquire all of PMSI's interest in such operating venture ("Source US") through the acquisition of PMSI Database to which PMSI contributed all of its interest in Source US. See "The Merger--General." Source provides critical competitive intelligence for client companies' sales representatives, linking the dispensed prescriptions back to the prescribers in their territory. Source also provides sales force managers with direct and comparative benchmarks to measure sales force performance and determine compensation at the individual territory level. Source's services enable client companies to target prescribers by their overall prescribing habits or by the mode of payment for prescriptions they write. Clients can identify the highest potential prescribers and their specific characteristics, and access market intelligence on the prescriber's practice. Other services match prescriptions to more than 850 health care payment plans, profiling the individual managed care plans and providing insight into their strategies. Source has recently launched new database services to enable pharmaceutical company clients to measure market share activity at the individual pharmacy level. For the year ended June 30, 1997 Source generated total revenues of $59.9 million and net income of $6.5 million. Source has 400 employees. Source's principal executive offices are located at 2394 East Camelback Road, Phoenix, Arizona, 85016 and its telephone number is (602) 381-9500.

The Merger Agreement provides that upon consummation of the Merger: (a) Subject to a working capital adjustment (discussed below), each outstanding share of Source Common Stock (excluding shares held by Source or any of its subsidiaries or by NDC or any of its subsidiaries, and excluding shares of Source Common Stock as to which dissenters' rights are perfected) issued and outstanding immediately prior to the Effective Time (hereinafter defined) shall cease to be outstanding and shall be converted into and exchanged for the right to receive the following: (i) the amount (the "Common Cash Amount"), if any, equal to the quotient of (A) $31,750,000 (the "Aggregate Cash Amount") less the Preferred Stock Merger Consideration (hereinafter defined), and less Source's expenses directly associated with this transaction (the "Transaction Expenses"), and (B) the total number of shares of Source Common Stock outstanding as of the Closing Date; (ii) that fraction of a share of NDC Common Stock equal to the quotient of (A) 1,099,716 shares (the "Payment Shares") less the Option Shares (hereinafter defined), and (B) the total number of shares of Source Common Stock outstanding as of the Closing Date (the "Common Base Exchange Ratio"); provided, however, if the sum of the Preferred Stock Merger Consideration (hereinafter defined) and the Transaction Expenses exceeds the Aggregate Cash Amount (the "Excess Expense"), then the Payment 8 Shares will be reduced by that number of shares of NDC Common Stock equal to the Excess Expense divided by the average of the daily closing sale prices of NDC Common Stock as reported on the NYSE Composite Transactions reporting system (as reported by The Wall Street Journal or, if not reported thereby, another authoritative source as chosen by NDC) for the ten consecutive full trading days in which such shares are traded on the NYSE ending at the close of trading on the last such day (the "Average Closing Price"), as of the Closing Date; and (iii) that fraction of a share of NDC Common Stock equal to the quotient of 455,840 shares (the "Stock Escrow") divided by the total number of shares of Source Common Stock outstanding as of the Closing Date (the "Common Escrow Exchange Ratio"). The Stock Escrow will be utilized for working capital adjustments and for indemnification claims by NDC, all pursuant to the terms of the Merger Agreement and an escrow agreement (the "Escrow Agreement") by and among NDC, the representative of the holders of Source Common Stock (the "Stockholder Representative") and an escrow agent. At the Closing Date, Source shall prepare and deliver to NDC a schedule indicating the expenses incurred but unpaid as of the Closing Date which are directly associated with the transactions contemplated by the Merger Agreement, including, without limitation, all expenses incurred in connection with Source's termination of certain employment agreements and an executive pension plan (in the aggregate such expenses hereinafter the "Transaction Expenses"). In addition, also at the Closing Date, Source shall have secured the cancellation of all outstanding options and warrants to purchase shares of Source Common Stock and shall provide to NDC a schedule of the number of shares of NDC Common Stock (the "Option Shares") payable to the holders of such options and warrants in consideration of such cancellation. Pursuant to the NDC Rights Agreement, each share of NDC Common Stock issued in connection with the Merger upon conversion of Source Common Stock shall be accompanied by an NDC Right. Based on the market price of NDC Common Stock on , 1997 and an estimate of the Transaction Expenses on such date, each outstanding share of Source Common Stock would receive $ and shares of NDC Common Stock. These amounts may change, however, at the Closing Date since the Transaction Expenses and the Option Shares will be determined on or immediately prior to the Closing Date. In addition, the Preferred Stock Merger Consideration is subject to adjustment in certain circumstances, on or prior to the Closing Date. See "Certain Differences in the Rights of NDC and Source Stockholders." (b) Each share of Source Preferred Stock (excluding shares held by Source or any of its subsidiaries or by NDC or any of its subsidiaries, and excluding shares of Source Preferred Stock as to which dissenters' rights are perfected) issued and outstanding immediately prior to the Effective Time shall cease to be outstanding and shall be converted and exchanged for the right to receive an amount equal to $11.33, subject to adjustment to equal that amount that a holder of Source Preferred Stock would otherwise be entitled to receive for each share of Source Preferred Stock if the Source Preferred Stock were redeemed on the Closing Date pursuant to the Designation (such aggregate amount, as adjusted, the "Preferred Stock Merger Consideration"). The amount of cash and shares of NDC Common Stock to be paid to the holders of Source Common Stock was determined based on a per share value for the NDC Common Stock of $43.875, the market price for the NDC Common Stock at the time NDC, Source and PMSI commenced negotiations. See "The Merger--Background of the Merger." Common Exchange Ratio Adjustment. If, at the close of trading on the tenth trading day immediately preceding the Closing Date (the "Determination Date"), the Average Closing Price shall be greater than $50.50 (the "Upper Threshold Price"), the "Common Exchange Ratios" (defined to include the Common Base Exchange Ratio and the Common Escrow Exchange Ratio) shall each be adjusted to equal that fraction of a share of NDC Common Stock (rounded to the nearest ten thousandth of a share) obtained by dividing the product of the Common Base Exchange Ratio or the Common Escrow Exchange Ratio, as the case may be, and the Upper 9 Threshold Price by the Average Closing Price at the Determination Date. If the Average Closing Price on the Determination Date shall be less than $37.25 (the "Lower Threshold Price"), Source shall have the right to refuse to consummate the Merger provided that Source shall have given written notice of such refusal to NDC not later than two trading days following the Determination Date. During the five-day period commencing with its receipt of such notice, NDC shall have the option, in its sole discretion, to elect to revise the Common Exchange Ratios to equal that fraction of a share of NDC Common Stock (rounded to the nearest ten thousandth of a share) obtained by dividing the product of the Common Base Exchange Ratio or the Common Escrow Exchange Ratio, as the case may be, and the Lower Threshold Price by the Average Closing Price at the Determination Date. If NDC makes the election contemplated by the preceding sentence within such five-day period, it shall give prompt written notice to Source of such election and the revised Common Exchange Ratios, whereupon the Merger Agreement shall remain in effect in accordance with its terms (except that the Common Exchange Ratios shall have been so modified). If the Lower Threshold Price is not reached, the Board of Directors of Source will take such action as is required by law and its fiduciary obligations, including, if appropriate, obtaining the consent of the Source stockholders to proceed with the Merger. Working Capital Adjustment. The Stock Escrow shall be adjusted in the manner described below: Preliminary Balance Sheet. Source will cause to be prepared and delivered to NDC a balance sheet for Source as of the most recent month ending more than ten days prior to the Closing Date (the "Preliminary Balance Sheet") and a certificate based on such Preliminary Balance Sheet setting forth Source's calculation of Working Capital, Current Assets and Current Liabilities (hereinafter defined) as of such date ("Estimated Working Capital," "Estimated Current Assets" and "Estimated Current Liabilities," respectively). The Preliminary Balance Sheet shall include and fairly present the consolidated financial position of Source and its subsidiaries as of the close of business on the date of the Preliminary Balance Sheet in accordance with generally accepted accounting principles ("GAAP") applied on a basis consistent with those used in the preparation of the consolidated balance sheet of Source and its subsidiaries at March 31, 1997 (the "Source Balance Sheet"). As used herein, "Working Capital" shall mean the amount equal to Current Assets less Current Liabilities; "Current Assets" shall mean the amount equal to the sum of cash, accounts receivable (net of any reserves), inventories, prepaid expenses, work-in-process, and any other current assets recognized by GAAP; and "Current Liabilities" shall mean the amount equal to the sum of accounts payable, accrued current liabilities of Source (other than the current portion of capitalized lease obligations), accrued sales commissions (but only as to revenues realized and included in the Source statements of income prior to such date), accrued bonuses (the amount equal to that percentage of budgeted annual bonuses for Source's fiscal year 1998 equal to the ratio of the earnings of Source through the date of calculation to budgeted earnings for the full fiscal year), accrued vacation pay, current portion of long-term indebtedness, pre- billed revenues and any other current liabilities recognized by GAAP, but excluding all Transaction Expenses. NDC shall have five business days from the receipt of the Preliminary Balance Sheet and the calculation of Estimated Working Capital, Estimated Current Assets and Estimated Current Liabilities to review such statement and calculations and following such review such statements and calculations shall be final and binding. If Estimated Current Assets are less than the product of (i) 0.9416 times (ii) Estimated Current Liabilities (such amount, the "Estimated Working Capital Adjustment") as of the date of the Preliminary Balance Sheet, the Stock Escrow payable by NDC shall be decreased by the number of shares of NDC Common Stock equal to the Estimated Working Capital Adjustment divided by the Average Closing Price as of the Closing Date; provided, however, in the event this reduction of the Stock Escrow exceeds 113,960 shares, the Payment Shares shall then be decreased similarly in an amount equal to such excess. Closing Balance Sheet. As promptly as practicable, but not later than 30 days after the Closing Date, NDC will cause to be prepared and delivered to the Stockholder Representative a balance sheet for Source as of the Closing Date (the "Closing Balance Sheet") setting forth NDC's calculation of Working Capital, Current Assets and Current Liabilities, each as of the Closing Date ("Closing Working Capital," "Closing Current 10 Assets" and "Closing Current Liabilities," respectively). The Closing Balance Sheet shall include and fairly present the consolidated financial position of Source and its subsidiaries as of the close of business on the Closing Date in accordance with GAAP applied on a basis consistent with those used in the preparation of the Source Balance Sheet. The Closing Balance Sheet and the calculation of Closing Working Capital, Closing Current Assets and Closing Current Liabilities shall be deemed final upon the earliest of (i) the date on which NDC and the Stockholder Representative jointly agree that such documents are final, (ii) the 30th day after delivery of such documents, if the Stockholder Representative has not delivered a notice to expressing disagreement with such calculations and setting forth its calculation of such amount(s), and (iii) the date on which all disputes relating to such statements and calculations between the parties are resolved. If the Stockholder Representative shall deliver a notice of disagreement, the Stockholder Representative and NDC, during the 30 days following such delivery, shall use their reasonable efforts to reach agreement on the disputed items or amounts (the "Disputed Amounts"). If, during such period, the Stockholder Representative and NDC are unable to reach such agreement, they shall promptly thereafter cause Price Waterhouse LLP (or if said firm shall be unwilling to act thereunder, such other independent accountants of nationally recognized standing reasonably satisfactory to NDC and the Stockholder Representative), promptly to review the Merger Agreement and any other documents necessary to calculate the Disputed Amounts (including all work papers of the parties used in calculating the Disputed Amounts) and such accountants shall then deliver a report to NDC and the Stockholder Representative setting forth their calculations which shall be final and binding. "Final Current Assets" and "Final Current Liabilities" mean (i) NDC's calculation of Closing Current Assets and Closing Current Liabilities, if no notice of disagreement with respect thereto is duly delivered by Source; or (ii) if such a notice of disagreement is delivered, (a) as agreed by NDC and Source or (b) in the absence of such agreement, as shown in the independent accountant's calculation. If Final Current Assets are less than the product of 0.9416 and Final Current Liabilities, as defined below (the amount of such shortfall referred to as, the "Final Working Capital Deficit"), the holders of Source Common Stock (the "Stockholders") shall pay to NDC the amount of the Final Working Capital Deficit out of the Stock Escrow in the manner provided in the Escrow Agreement. If Final Current Assets are greater than the product of 0.9416 and Final Current Liabilities (the amount of such surplus referred to as, the "Final Working Capital Surplus"), NDC shall pay to the escrow agent, to be held in accordance with the Escrow Agreement, that number of shares of NDC Common Stock equal to the quotient of the Final Working Capital Surplus divided by the Average Closing Price as of the date Final Working Capital was determined. Allocation with PMSI. NDC, Source and PMSI have agreed to the following adjustment in order to properly allocate the working capital adjustment based on their respective Closing Balance Sheets. For purposes of such allocation, "Total Current Assets" shall mean the sum of Final Current Assets and "Final Current Assets" calculated pursuant to the Stock Purchase Agreement; "Total Current Liabilities" shall mean the sum of Final Current Liabilities and "Final Current Liabilities" calculated pursuant to the Stock Purchase Agreement; "Current Asset Allocation Amount" shall mean the product of (1) Final Current Assets divided by Total Combined Assets, and (2) the Total Working Capital Deficit or Total Working Capital Surplus, as the case may be; and "Total Combined Assets" shall mean the sum of Final Current Assets and "Final Current Assets" calculated under the Stock Purchase Agreement. If Total Current Assets are less than the product of (i) 0.9975 times (ii) Total Current Liabilities (the "Total Working Capital Deficit"), then the Stockholders shall pay to NDC the Current Asset Allocation Amount out of the Stock Escrow in the manner provided in the Escrow Agreement. If Total Current Assets are greater than the product of (i) 0.9975 times (ii) Total Current Liabilities (the "Total Working Capital Surplus"), then NDC shall pay to the Stockholders pursuant to the instructions of the Stockholder Representative that number of shares of 11 NDC Common Stock equal to the quotient of the Current Asset Allocation Amount and the Average Closing Price as of the date Final Working Capital was determined. For purposes of any adjustments based on the Closing Balance Sheet, the parties shall take into account any adjustment made at closing pursuant to the Preliminary Balance Sheet. Indemnification. Pursuant to the Merger Agreement, the Stockholders jointly and severally agree to indemnify, defend, and hold harmless NDC, Source, and their respective officers, directors, controlling persons, affiliates and representatives, and each of them (the "Indemnitees"), from, against, for and in respect of any and all losses asserted against, or paid, suffered or incurred by, an Indemnitee and resulting from, based upon, or arising out of: (a) the inaccuracy, untruth, incompleteness or breach of any representation or warranty of any Stockholder or Source contained in or made pursuant to the Merger Agreement or in any certificate, schedule, or exhibit furnished by the Stockholders or Source in connection therewith; (b) a breach of or failure to perform any covenant or agreement of the Stockholders or Source made in the Merger Agreement; (c) any and all taxes arising out of or associated with the Divestiture; (d) any and all taxes arising out of or associated with certain sales by Source; or (e) any and all losses relating to certain litigation ongoing as of the date of the Merger Agreement. The Stockholders will have no liability to the Indemnitees under or in connection with a breach of any of the representations, warranties, covenants or agreements made or to be performed by the Stockholders or Source contained in the Merger Agreement unless written notice asserting an indemnification claim based thereon is given to the Stockholder Representative prior to August 31, 1999. The Stockholders shall have no liability with respect to the matters described above until the total of all losses with respect thereto exceeds $200,000 in which event the Stockholders shall be obligated to indemnify the Indemnitees for all such losses; provided, however, that each individual claim of $10,000 or less shall not be indemnifiable, and shall not be included in determining whether the $200,000 threshold has been reached. In no event shall the aggregate liability of the Stockholders exceed the lesser of (i) the aggregate value of the Indemnification Escrow Amount (hereinafter defined), and (ii) $20,000,000. All disputes arising under the indemnification provisions of the Merger Agreement (other than claims in equity) shall be resolved by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association. Escrow Agreement. Pursuant to the terms of the Merger Agreement, the Stock Escrow (455,840 shares of NDC Common Stock decreased by the adjustment, if any, based on the Preliminary Balance Sheet discussed above), will be distributed to and will be held by the escrow agent pursuant to the terms of the Escrow Agreement, a copy of which is attached to this Proxy Statement/Prospectus as Annex C. Working Capital Escrow. A total of 113,960 of the Stock Escrow shares, less any shares paid to NDC as the result of an adjustment based on the Preliminary Balance Sheet, are reserved to cover an adjustment, if any, based on the Closing Balance Sheet (the "Working Capital Escrow Amount"). The Stockholder Representative, or the Stockholders with respect to their individual percentage interest, may direct the escrow agent to sell, from time to time, any or all of the shares of NDC Common Stock in the Working Capital Escrow Amount at such prices as are commercially reasonable at the time of sale. Any and all cash proceeds from the sale of such shares shall remain in escrow as part of the Working Capital Escrow Amount, except that at the end of each calendar month, if the aggregate value of the Working Capital Escrow Amount exceeds 133% of the aggregate value of the Stock Escrow as of the Closing Date, the Escrow Agent shall distribute to the Stockholders that amount in cash or shares of NDC Common Stock equal to their respective percentage interest in such surplus. 12 If, prior to the ninetieth day after the Effective Time (the "Distribution Date" with respect to the Working Capital Escrow Amount), NDC shall be entitled to an adjustment based on the Closing Balance Sheet, the escrow agent shall distribute to NDC from the Working Capital Escrow Amount an amount in cash, in immediately available funds, equal to such adjustment claim, and, if the Working Capital Escrow Amount does not contain any cash, or contains an amount of cash insufficient to satisfy the claim, then the escrow agent shall distribute to NDC from the Working Capital Escrow Amount that number of shares of NDC Common Stock equal to the quotient (rounded to the next highest whole number) obtained by dividing the amount of the claim not paid in cash by the Average Closing Price as of the date Final Working Capital was determined. If the adjustment based on the Closing Balance Sheet is pending as of the Distribution Date with respect to the Working Capital Escrow Amount, the escrow agent shall retain an amount equal to the disputed claim amount and promptly deliver to the Stockholders a distribution of cash, if any, in immediately available funds, and shares of NDC Common Stock from the Working Capital Escrow Amount equal to any remaining amounts in the Working Capital Escrow Amount. The disputed amount shall be paid to NDC or the Stockholders, as the case may be, upon the final resolution as agreed by NDC and the Stockholder Representative in writing of the amount of the adjustment claim. Indemnification Escrow. A total of 341,880 of the Stock Escrow shares are reserved to cover claims by NDC based on the indemnification provisions of the Merger Agreement (the "Indemnification Escrow Amount"). The Stockholder Representative, or the Stockholders with respect to their individual percentage interest, may direct the escrow agent to sell, from time to time, any or all of the shares of NDC Common Stock in the Indemnification Escrow Amount at such prices as are commercially reasonable at the time of sale. Any and all cash proceeds from the sale of such shares shall remain in escrow as part of the Indemnification Escrow Amount, except that at the end of each calendar month, if the aggregate value of the Indemnification Escrow Amount exceeds $20,000,000, the escrow agent shall distribute to the Stockholders that amount in cash or shares of NDC Common Stock equal to their respective percentage interest in such surplus. If, prior to August 31, 1999 (the "Distribution Date" with respect to the Indemnification Escrow Amount) NDC shall be entitled to a payment based on an indemnification claim, the escrow agent shall distribute to NDC from the Indemnification Escrow Amount an amount in cash, in immediately available funds, equal to such claim, and, if the Indemnification Escrow Amount does not contain any cash, or contains an amount of cash insufficient to satisfy the claim, then the escrow agent shall distribute to NDC from the Indemnification Escrow Amount that number of shares of NDC Common Stock equal to the quotient (rounded to the next highest whole number) obtained by dividing the amount of the claim not paid in cash by the Average Closing Price as of the date the notice of claim was received by the escrow agent. If an indemnification claim is pending as of the Distribution Date with respect to the Indemnification Escrow Amount, the escrow agent shall retain an amount equal to the disputed claim amount and promptly deliver to the Stockholders a distribution of cash, if any, in immediately available funds, and shares of NDC Common Stock from the Indemnification Escrow Amount, equal to any remaining amounts in the Indemnification Escrow Amount. The disputed amount shall be paid to NDC or the Stockholders, as the case may be, upon the final resolution as agreed by NDC and the Stockholder Representative in writing of the amount of the outstanding claim. General. Any and all cash dividends or other cash income with respect to the Stock Escrow shall be paid into and remain in escrow and shall be available for purposes of adjustments or distributions. Each Stockholder shall have the right to direct the escrow agent in writing as to the exercise of voting rights with respect to shares in the Stock Escrow held by the escrow agent on behalf of such Stockholder, and the escrow agent shall comply with any such directions if received in a timely manner. In the absence of such directions, the escrow agent shall not vote any such shares in the Stock Escrow. The escrow agent shall invest the cash amount, if any, included in the Working Capital and Indemnification Escrow Amounts as directed by the Stockholder Representative or the Stockholders, provided that should the Stockholder Representative or the Stockholders fail to so direct the escrow agent, NDC shall be authorized to so direct the escrow agent, and, 13 provided further that such investments shall be limited to (i) direct obligations of the United States of America, (ii) obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of principal and interest, (iii) commercial paper rated of the highest quality by Moody's Investors Service, Inc. ("Moody's") or Standard & Poor's Ratings Group, a division of McGraw-Hill Inc. ("S&P"), and (iv) certificates of deposit issued by a commercial bank (which may be the escrow agent or any affiliate of the escrow agent) whose long-term debt obligations are rated at least A2 by Moody's or at least A by S&P, in each case having a maturity not in excess of 90 days, or a money market fund that invests exclusively in said investments. The Stockholder Representative. The Stockholder Representative shall mean a committee comprised of Messrs. Dennis Turner, Handel Evans and Patrick Welsh. Mr. Turner is the Chief Executive Officer and a director of Source. Mr. Evans is the Chairman of the Board of Directors of Source. Mr. Welsh is a director of Source and a general partner of the respective sole general partners of several affiliated private investment funds, including Welsh, Carson, Anderson & Stowe V, L.P. and Welsh, Carson, Anderson & Stowe IV, L.P., that are stockholders of Source. The Stockholder Representative shall have the responsibility and authority to enforce any adjustment based on the Closing Balance Sheet, the indemnification provisions of the Merger Agreement, and the terms and conditions of the Escrow Agreement, all on behalf of the Stockholders. Votes Required. Adoption of the Merger Agreement and consummation of the transactions contemplated therein requires the affirmative vote of the holders of a majority of the outstanding shares of Source Common Stock and Source Preferred Stock entitled to vote at the Special Meeting, voting as a single class, and of the holders of a majority of the outstanding shares of Source Preferred Stock entitled to vote at the Special Meeting. As of the Record Date, Source's directors and executive officers, and their affiliates, held approximately 74.9% of the outstanding shares of Source Common Stock entitled to vote at the Special Meeting and 50% of the outstanding shares of Source Preferred Stock entitled to vote at the Special Meeting. Pursuant to the Voting Agreement (hereinafter defined), the holders of approximately 98% of the outstanding shares of Source Preferred Stock have agreed to vote all of their shares of Source Preferred Stock in favor of adoption of the Merger Agreement. See "General Information--Voting Agreement." As of the Record Date, NDC, its directors and executive officers, and their affiliates, held no shares of Source Common Stock or Source Preferred Stock. Recommendation of the Source Board of Directors. The Board of Directors of Source believes that the Merger is in the best interests of Source and its stockholders and has unanimously approved the Merger Agreement and the consummation of the transactions contemplated therein. The Source Board of Directors unanimously recommends that the stockholders vote FOR adoption of the Merger Agreement and the consummation of the transactions contemplated therein. In deciding to approve the Merger Agreement and the consummation of the transactions contemplated therein, Source's Board of Directors considered a number of factors, including the terms of the Merger, the compatibility of the operations of Source and NDC, and the financial condition, results of operations, and future prospects of Source and NDC. See "The Merger--Reasons for the Merger." Effective Time and Closing Date. If the Merger is adopted by the requisite votes of the Source stockholders, all required governmental and other consents and approvals are obtained, and the other conditions to the obligations of the parties to consummate the Merger are either satisfied or waived (as permitted), the Merger will be consummated and will become effective on the date and at the time that a Certificate of Merger, reflecting the Merger, becomes effective with the Secretary of State of the State of Delaware (the "Effective Time"). Assuming satisfaction of all conditions to consummation, the Merger is expected to become effective during the fourth quarter of calendar 1997. NDC and Source each has the right, acting unilaterally, to terminate the Merger Agreement should the Merger not be consummated by January 31, 1998. The closing of the Merger shall take place on the date the Effective Time occurs or such other date as the parties shall agree (the "Closing Date") which NDC and Source anticipate will be not more than five business days following the Special Meeting. See "The Merger--Effective Time and Closing Date" and "--Amendment, Waiver, and Termination." 14 Delivery of NDC Certificates. Promptly after the Effective Time, each record holder of shares of Source Common Stock and Source Preferred Stock ("Source Capital Stock") outstanding at the Effective Time will be mailed a transmittal letter (with instructions) to use in effecting the surrender and cancellation of Source Capital Stock certificates in exchange for NDC Common Stock and/or cash. NDC shall not be obligated to deliver the consideration to which any former holder of Source Capital Stock is entitled until such holder surrenders such holder's certificate or certificates representing such holder's shares of Source Capital Stock for exchange. The certificate or certificates so surrendered shall be duly endorsed as the exchange agent may require. See "The Merger--Distribution of NDC Certificates." Certain Federal Income Tax Consequences. The Merger is intended to be a tax- free reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"). No opinion of counsel or Internal Revenue Service regarding tax consequences of the Merger has been or will be secured in connection with the Merger. Assuming the Merger qualifies as a reorganization, no gain or loss should be recognized for federal income tax purposes by Source stockholders as a result of the Merger, except that gain or loss will be recognized with respect to cash received in lieu of fractional shares or as a result of the exercise of appraisal rights. If for any reason the Merger does not so qualify, exchanging stockholders will recognize gain or loss on a sale of their stock. A discussion of matters regarding qualification for tax free reorganization treatment is set forth below. Upon the sale or exchange of NDC Common Stock, a holder of such stock generally will recognize capital gain or loss equal to the difference between the amount of cash and the fair market value of any property received upon the sale or exchange and such holder's adjusted tax basis in the NDC Common Stock. Under recently enacted legislation, long-term capital gains recognized by certain non-corporate holders of NDC Common Stock generally will be subject to a maximum federal income tax rate of 20% if the shares sold or exchanged are held for more than 18 months, and to a maximum federal income tax rate of 28% if such shares are held for more than one year but are not held for more than 18 months. Tax consequences to dealers in NDC Common Stock, non-United States holders of NDC Common Stock or others who have a special tax status or to persons who received their shares through the exercise of employee stock options or otherwise as compensation may be different and such persons should consult their tax advisors as to the tax consequences of a sale or exchange of NDC Common Stock." See "The Merger--Certain Federal Income Tax Consequences." BECAUSE CERTAIN TAX CONSEQUENCES OF THE MERGER MAY VARY DEPENDING UPON THE PARTICULAR CIRCUMSTANCES OF EACH STOCKHOLDER AND OTHER FACTORS, AND BECAUSE VARIOUS FACTUAL MATTERS MUST BE RESOLVED FAVORABLY FOR TAX FREE REORGANIZATION TREATMENT TO APPLY, EACH HOLDER OF SOURCE CAPITAL STOCK IS URGED TO CONSULT SUCH HOLDER'S OWN TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE MERGER (INCLUDING THE APPLICATION AND EFFECT OF FOREIGN, STATE AND LOCAL INCOME AND OTHER TAX LAWS). Interests of Certain Persons in the Merger. Certain members of Source's management and the Board of Directors of Source have interests in the Merger in addition to their interests as stockholders of Source generally. These include, among other things, provisions in the Merger Agreement relating to indemnification and eligibility for certain NDC employee benefits and provisions regarding severance in agreements between Source and certain of its executive officers. See "The Merger--Management and Operations After the Merger" and "--Interests of Certain Persons in the Merger." Conditions To Consummation. Consummation of the Merger is subject to various conditions, including among other matters: (i) adoption of the Merger Agreement by the requisite votes of Source stockholders; (ii) receipt of all governmental and other consents and approvals necessary to permit consummation of the Merger, including expiration or termination of the statutory waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 ("HSR Act") (which expiration occurred on November 7, 1997); (iii) consummation of the Stock Purchase; (iv) the consummation of the Divestiture; (v) consummation of certain agreements related 15 to the Merger Agreement; (vi) cancellation by Source of all outstanding options and warrants; and (vii) satisfaction of certain other traditional conditions. The foregoing are the material conditions to the consummation of the Merger. See "The Merger--Conditions to Consummation" and "--Amendment, Waiver, and Termination." Regulatory Approvals. The statutory waiting period under the HSR Act expired on November 7, 1997. See "The Merger--Regulatory Approvals." Conduct Of Business Pending The Merger. Pursuant to the Merger Agreement, Source has agreed, among other things, to operate its business only in the ordinary course and to take no action that would adversely affect its ability to perform its covenants and agreements under the Merger Agreement. In addition, Source has agreed not to take certain actions relating to the operation of Source pending consummation of the Merger without the prior written consent of NDC, except as otherwise permitted by the Merger Agreement, including: (i) amending its Certificate of Incorporation or Bylaws; (ii) entering into, modifying, amending or terminating any material contract; (iii) repurchasing, redeeming or otherwise acquiring any shares of Source Capital Stock; (iv) subject to certain exceptions, issuing any additional shares of Source Capital Stock or giving any person the right to acquire any such shares, or issuing any long-term debt; (v) subject to certain exceptions, granting any increase in compensation or benefits, or paying any bonus, to any of its directors, officers or employees; or (vi) modifying or adopting any employee benefit plans, including any employment contract. Furthermore, Source has agreed that prior to the Effective Time, it shall (i) consummate the Divestiture; (ii) terminate certain employment agreements and its executive pension plan; and (iii) satisfy all intercompany accounts in connection with the Divestiture. See "The Merger--Conduct of Business Pending the Merger." Termination. The Merger Agreement may be terminated, and the Merger abandoned, at any time prior to the Effective Time by mutual consent of the Boards of Directors of Source and NDC. In addition, the Merger Agreement may be terminated, and the Merger abandoned, prior to the Effective Time by either NDC or Source if (i) the other party materially breaches and does not timely cure any representation, warranty, covenant or other agreement contained in the Merger Agreement, (ii) any consent or approval of certain regulatory authorities is denied by final nonappealable action of such authority or if any action taken by such authority is not appealed within the time limit for appeal, (iii) the Source stockholders fail to adopt the Merger Agreement and the transactions contemplated thereby at the Special Meeting, (iv) any of the conditions precedent to the obligations of the terminating party to consummate the Merger cannot be satisfied or fulfilled by January 31, 1998, or (v) the Merger has not been consummated by January 31, 1998. In addition, NDC may unilaterally terminate the Merger Agreement if the Source Board of Directors fails to reapprove or resolves not to affirm the Merger or recommends entering into a transaction other than the Merger involving a merger, share exchange, consolidation or transfer of substantially all of Source's assets. Furthermore, Source may unilaterally terminate the Merger Agreement in the event that the Average Closing Price of the shares of NDC Common Stock is less than the Lower Threshold Amount as of the Determination Date, subject to NDC's right to revise the Common Exchange Ratios based on the Lower Threshold Price. See "--Common Exchange Ratio Adjustment" and "The Merger--Amendment, Waiver and Termination." Expenses And Fees. The Merger Agreement provides that each party shall be responsible for its own costs and expenses incurred in connection with the negotiation and consummation of the transactions contemplated by the Merger Agreement, except that each of NDC and Source shall pay one-half of the filing fees payable in connection with the HSR filings, and NDC shall pay all costs associated with the Registration Statement and this Proxy Statement/Prospectus and printing costs incurred in connection with the Registration Statement and this Proxy Statement/Prospectus. If the Merger Agreement is terminated because (i) Source shall fail to call the Special Meeting, (ii) the stockholders of Source fail to approve the Merger, (iii) the Board of Directors of Source, to the exclusion of a competing proposal, shall fail to reaffirm its approval of the Merger or shall have affirmed, recommended or authorized another merger, share exchange, consolidation or transfer of substantially all of the assets of Source 16 (a "Competing Proposal"), or (iv) Source has entered a binding agreement with respect to a Competing Proposal, then Source shall promptly pay NDC all the out-of-pocket costs and expenses of NDC, including costs of counsel, investment brokers, actuaries and accountants up to a maximum of $750,000 (the "NDC Expenses"). In addition to the foregoing, if the Merger Agreement is terminated because (i) Source fails to call the Special Meeting, or (ii) the stockholders of Source fail to approve the Merger Agreement, then Source shall pay to NDC the NDC Expenses plus $3,000,000. Further, if within twelve months following the termination of this Agreement: (i) by NDC because Source's Board of Directors shall have failed to reaffirm its approval of the Merger or shall have affirmed, recommended or authorized the entering into any other merger, share exchange, consolidation or transfer of substantially all of the assets of Source; or, (ii) by Source because it has entered into negotiations with a third party relating to the foregoing and pursuant to the continuing fiduciary duties of Source's Board of Directors as required by applicable law, Source has entered into a binding agreement with such third party; any third-party shall acquire, merge with, combine with, purchase substantially all of the assets of, or engage in any other business combination with, or purchase any equity securities involving an acquisition of 50% or more of the voting stock of Source, or enter into any binding agreement to do any of the foregoing, such third-party that is a party to the business combination shall pay to NDC, as a condition to consummation of such business combination, an amount in cash equal to $3,000,000. Accounting Treatment. It is anticipated that the Merger will be accounted for under the "purchase" method of accounting. See "The Merger--Accounting Treatment." Resale of NDC Common Stock. The NDC Common Stock issued in connection with the Merger will be freely transferable by the holders of such shares, except for those holders who may be deemed to be "affiliates" (generally including directors, certain executive officers and holders of 10% or more of the outstanding capital stock) of Source or NDC under applicable federal securities laws. See "The Merger--Resale of NDC Common Stock." Voting Agreement. NDC and the holders of a majority of Source Preferred Stock (the "Preferred Stockholders") have entered into a voting agreement (the "Voting Agreement") which provides that the Preferred Stockholders will vote such Preferred Stockholder's shares of Source Preferred Stock in favor of the Merger, the execution and delivery by Source of the Merger Agreement and the approval of the terms thereof and each of the other transactions contemplated by the Merger Agreement, provided that the Merger Agreement has not been amended or waived so as to in any manner (i) affect the rights of the Preferred Stockholders or their representatives or increase the Preferred Stockholders' obligations thereunder or (ii) increase the consideration payable to the holders of Source Common Stock, without the prior consent of the Preferred Stockholders. The Voting Agreement also provides that the Preferred Stockholders shall vote (or cause to be voted) such Preferred Stockholder's shares of Source Preferred Stock against (i) any merger agreement or merger (other than the Merger Agreement and the Merger), consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by Source or (ii) any amendment of Source's Certificate of Incorporation or Bylaws or other proposal or transaction involving Source or any of its subsidiaries which amendment or other proposal or transaction would in any manner impede, frustrate, prevent or nullify the Merger, the Merger Agreement or any of the other transactions contemplated by the Merger Agreement. Each Preferred Stockholder has also agreed that such Stockholder shall not (i) transfer, or consent to any transfer of, any or all of the such stockholder's shares or any interest therein, except pursuant to the Merger; (ii) enter into any contract, option or other agreement or understanding with respect to any transfer of any or all of such shares or any interest therein, (iii) grant any proxy, power of attorney or other authorization in or with respect to such shares, except for the Voting Agreement, or (iv) deposit such shares into a voting trust or enter into a voting agreement or arrangement with respect to such shares, subject to certain limited exceptions. 17 The Voting Agreement will terminate upon the earlier of the Effective Time, the date upon which the Merger Agreement is terminated in accordance with its terms, or December 15, 1997. Appraisal Rights. Holders of Source Capital Stock have the right to demand appraisal of their shares of Source Capital Stock and, upon satisfaction of certain specified procedures, to receive cash in respect of the "fair value" (as defined by Delaware law) of their shares of Source Capital Stock in accordance with applicable Delaware law. The procedures to be followed by dissenting stockholders are summarized under "The Merger--Appraisal Rights" and a copy of the applicable Delaware statutory provisions is set forth in Annex B to this Proxy Statement/Prospectus. FAILURE TO FOLLOW SUCH PROVISIONS PRECISELY MAY RESULT IN LOSS OF APPRAISAL RIGHTS. In general, any dissenting stockholder who perfects his statutory appraisal rights to be paid the "fair value" of his Source Capital Stock in cash will recognize gain or loss for federal income tax purposes upon receipt of such cash. See "The Merger--Certain Federal Income Tax Consequences." DIVESTITURE OF SOURCE EUROPE Concurrent with the Merger, and as a condition of closing, Source will divest Source Europe. Source Europe is a development stage business focused on building a range of services similar to Source's United States operations ("Source US"), for clients in continental Europe. While Source Europe is currently developing software and databases to deliver prescriber-linked prescription services and has delivered initial services to certain clients, the business will need further funding to continue business development through cash flow selfsufficiency. Source Europe may also require additional investment in the event of problems with the development of the software and databases, delays in bringing products to market or delays in obtaining government approval to launch prescriber-based services in certain countries. Source Europe has incurred operating losses since inception in 1994. In June 1997, PMSI and Source commenced negotiations on a proposal for PMSI to acquire 100% of Source Europe. Source appointed investment bankers to negotiate on its behalf, and a specially formed committee of PMSI's independent directors not affiliated with Source retained investment bankers to negotiate for PMSI. On August 20, 1997, NDC, Source and PMSI executed definitive agreements whereby PMSI will acquire 100% of Source Europe and NDC will acquire 100% of Source US (including PMSI's interest in Source) together with the Over- the-Counter Physician Database business of PMSI (the "OTC Business"), for a total purchase price of $153.0 million, payable 75% in registered shares of NDC Common Stock and 25% in cash. The Merger Agreement and the Stock Purchase Agreement are subject to the approval of the stockholders of Source and PMSI. In negotiating the terms of the transfer of Source Europe to PMSI, Source acknowledged that the current value of Source Europe is inherently speculative, given the risks associated with such business, and that PMSI would be assuming significant risks in agreeing to complete the development and commercialization of Source Europe. Source also recognized that, if such risks could be overcome, the projections of Source Europe's cash flows prepared by Source's management would indicate a significantly higher discounted present value than the negotiated current value of Source Europe, which reflected the risks to achieving successful commercialization. Under all the circumstances, including the desire of Source's Board to take advantage of NDC's attractive proposal to acquire the rest of Source, the need for additional resources to complete the development and commercialization of Source Europe and the absence of any other offers to acquire Source Europe, the Source Board concluded that the terms of the transfer of Source Europe were fair to Source stockholders. See "The Merger--Background of the Merger" and "The Merger--Certain Federal Income Tax Consequences." 18 MARKET PRICES AND DIVIDENDS NDC Common Stock is traded on the NYSE under the symbol "NDC."

On November 10, 1997, the last reported sale prices per share of NDC Common Stock on the NYSE was $36.625. SOURCE STOCKHOLDERS SHOULD OBTAIN CURRENT MARKET QUOTATIONS FOR NDC COMMON STOCK. The Merger Agreement provides for the filing of a listing application with the NYSE covering the shares of NDC Common Stock issuable pursuant to the Merger. It is a condition to consummation of the Merger that NDC use its reasonable efforts to ensure that such shares of NDC Common Stock be authorized for listing on the NYSE effective upon official notice of issuance. See "The Merger--Conditions to Consummation." 19 COMPARISON OF CERTAIN UNAUDITED PER SHARE DATA The following summary presents selected comparative unaudited per share data for NDC and Source on a historical basis and on a pro forma combined basis assuming the Merger and the Stock Purchase had been effective during the period presented, and on an equivalent pro forma combined basis assuming the Merger and the Stock Purchase had been effective during the period presented.

RECENT DEVELOPMENTS On October 14, 1997, NDC signed a definitive agreement to acquire Physician Support Systems, Inc., a publicly-held Delaware corporation ("PSS"), in exchange for approximately 4,230,000 shares of NDC Common Stock. PSS provides business management services to physicians and hospitals in 29 states. For the year ended December 31, 1996 and the nine months ended September 30, 1997, PSS reported total revenues of $75.2 million and $81.7 million, respectively, and net loss of $9.7 million and pro forma net income of $2.7 million, respectively. As of September 30, 1997, PSS had total consolidated assets of $117.4 million and consolidated stockholders' equity of $52.0 million. The PSS transaction is subject to the approval of the PSS stockholders as well as other standard closing conditions and is expected to close by January 31, 1998. On November 6, 1997, NDC announced that Robert L. Walker will become chief financial officer of NDC effective December 1, 1997. Mr. Walker previously served as chief financial officer of Providian Corporation, a Louisville, Kentucky based insurance and financial services company whose business includes credit card and other consumer lending offerings. 20 SELECTED FINANCIAL DATA Set forth below is certain unaudited historical consolidated selected financial data relating to NDC and Source and certain unaudited pro forma combined selected financial data, giving effect to the Merger and the Stock Purchase on a purchase accounting basis.

The pro forma combined financial information represents the historical operations of NDC, Source and PMSI Database adjusted for the effects of the Merger and the Stock Purchase as well as the effects of NDC's acquisition of NDC Healthcare EDI Services, Inc. consummated in October 1996. This information has also been adjusted to conform presentation format and accounting policy to those of NDC. For comparability purposes, Source and PMSI Database's three months ended September 30, 1997 and twelve months ended June 30, 1997, respectively, are used in conjunction with the NDC three and twelve months ended August 31, 1997 and May 31, 1997. The weighted average common shares outstanding and related per share data has been adjusted to reflect the maximum number of shares of NDC Common Stock issuable in the Merger and the Stock Purchase. The pro forma combined financial information is provided for informational purposes only and is not necessarily indicative of actual results that would have been achieved had the Merger and the Stock Purchase been consummated at the beginning of the period presented or of future results. Historically, the financial results of Source US (the principal business of Source and PMSI Database, operated as a joint venture) have varied from quarter to quarter. These fluctuations are principally due to the timing of customer commitments to new products and services and the timing of delivery of Source US services. For example, many of the pharmaceutical manufacturing customers of Source US report results on a calendar year basis. In general, commitments are made by Source US's customers in the summer and fall for delivery in the first part of the next calendar year. Source US's fiscal year begins July 1. Source typically incurs expenses during the first half of its fiscal year (the last half of the calendar year) in preparation for roll-out of new products and services to meet customer requirements. Consequently, during Source US's first quarter, significant expense with respect to new products is incurred to generate revenues which should be recognized in future quarters. See "Source Informatics Inc.--Management's Discussion and Analysis of Financial Condition and Results of Operations." The selected pro forma combined financial information is derived from the Pro Forma Combined Financial Information attached to this Proxy Statement/Prospectus as Annex E. This information should be read in conjunction with the historical financial statements of NDC and Source, including the respective notes thereto, appearing elsewhere or incorporated by reference herein.

COMPETITION The markets for the applications systems and services offered by NDC are highly competitive. Competition in the health care transaction processing and payment systems markets affects NDC's ability to gain new customers and the prices it can charge. The key competitive factors for NDC are functionality of products, quality of service and price. Many of NDC's competitors have access to significant capital and management, marketing and technological resources that are equal to or greater than those of NDC, and there can be no assurance that NDC will continue to be able to compete successfully with them. In addition, NDC competes with businesses that internally perform data processing or other services offered by NDC. MARKETS AND APPLICATIONS NDC's future growth and profitability will depend, in part, upon the further expansion of the health care transaction processing and payment systems markets, the emergence of other markets for electronic transaction processing services and NDC's ability to penetrate such markets. Further expansion of these markets is dependent upon the continued growth in the number of transactions available to be processed and the continued automation of traditional paper-based processing systems. NDC's ability to penetrate such markets will depend, in turn, upon its ability to apply its existing technology, or to develop new technology, to meet the particular service needs of each new market. There can be no assurance that markets for NDC's services will continue to expand and develop or that NDC will be successful in its efforts, or have adequate financial, marketing and technological resources to penetrate new markets. INTEGRATED PAYMENT SYSTEMS BUSINESS NDC's merchant customers have liability for charges disputed by cardholders. However, in the case of merchant fraud, or insolvency or bankruptcy of the merchant, NDC may be liable for any of such charges disputed by cardholders. NDC requires cash deposits and other types of collateral by certain merchants to minimize any such contingent liability. Based on its historical loss experience, NDC has established reserves for estimated losses on transactions processed which management believes are adequate. There can be no assurance, however, that such reserves for losses will be adequate. Any such losses in excess of reserves could have a material adverse effect on the financial condition and results of operations of NDC. HEALTH CARE INFORMATION SERVICES Federal and state governments have recently focused significant attention on health care reform. It is not possible to predict which, if any, proposal that has been or will be considered will be adopted. There can be no assurance that the health care regulatory environment will not change so as to restrict the existing operations of, impose additional requirements on or limit the expansion of NDC. Costs of compliance with changes in government regulations may not be subject to recovery by NDC through price increases. Significant media and public attention has recently been focused on the health care industry due to ongoing federal and state investigations purportedly related to certain referral and billing practices. The Office of the Inspector General and the Department of Justice have initiated hospital and laboratory billing review projects in certain states and are expected to extend such projects to additional states, including states in which NDC, upon the consummation of its acquisition of PSS, will operate. These projects increase the likelihood of governmental investigations of hospitals, laboratories and other institutions for which NDC and PSS perform services. Although PSS currently monitors, and, upon the consummation of its acquisition of PSS, NDC intends to continue to monitor, billing practices and arrangements to ensure compliance with prevailing industry practices under applicable laws, such laws are complex and constantly evolving and there can be no assurance that governmental investigators will not take positions that are inconsistent with industry practices. 24 ACQUISITION RISKS NDC completed five acquisitions in fiscal 1997, and intends to seek additional acquisition opportunities and alliance relationships with other businesses that will allow it to increase its market penetration, technological capabilities, product offerings and distribution capabilities. There can be no assurance that NDC will be able successfully to identify suitable acquisition candidates, complete acquisitions, integrate acquired operations into its existing operations or expand into new markets. There can also be no assurance that future acquisitions will not have an adverse effect upon NDC's operating results, particularly in the fiscal quarters immediately following the completion of such acquisitions while the operations of the acquired business are being integrated into NDC's operations. Once integrated, acquired operations may not achieve levels of revenues, profitability or productivity comparable with those achieved by NDC's existing operations, or otherwise perform as expected. Specifically, with regard to the acquisition of Source, certain products currently under development may never reach technological feasibility which could have a material adverse effect upon NDC's operating results. See "Annex E--Pro Forma Financial Information." NDC may incur indebtedness in the future, including through borrowings under a credit facility, if a credit facility is available, to finance acquisitions. As a result, NDC expects to be subject to risks associated with debt financing, including the risk that interest rates may increase, the risk that NDC's cash flow will be insufficient to meet required payments on its debt and the risk that NDC may be unable to refinance or repay the debt as it comes due. In addition, NDC competes for acquisition and expansion opportunities with companies that have substantially greater resources. ANTI-TAKEOVER PROVISIONS OF DELAWARE LAW, CERTAIN CHARTER AND BY-LAW PROVISIONS AND STOCKHOLDER RIGHTS PLAN Certain provisions of NDC's Certificate of Incorporation and By-laws could delay, defer or prevent a takeover attempt that a stockholder might consider in its best interest. These provisions may adversely affect prevailing market prices for NDC Common Stock. These provisions, among other things, classify NDC's Board of Directors into three classes as nearly equal in number as the total number of directors permits, each of which serves for different three- year terms, and authorize the Board of Directors to issue preferred stock in one or more classes or series and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any action on the part of the stockholders. The rights of the holders of NDC Common Stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of the outstanding voting stock of NDC. NDC has no current plans to issue shares of preferred stock. NDC also maintains a stockholder rights plan which entitles its stockholders , upon the happening of certain events, to purchase preferred stock of NDC. These NDC Rights (hereinafter defined) may have certain anti-takeover effects because the rights will cause substantial dilution to a person or group that attempts to acquire NDC on terms not approved by the Board of Directors of NDC unless the offer is conditioned on a substantial number of NDC Rights being acquired. In addition, Section 203 of the Delaware General Corporation Law ("DGCL") prohibits certain persons from engaging in business combinations with NDC, which may also have the effect of delaying, deterring or preventing a change of control of NDC. NEW PRODUCT INTRODUCTIONS With NDC's acquisition of Source and PMSI Database, NDC plans to introduce products and services different from those NDC has traditionally provided. The market for these products and services is characterized by rapid technological change, frequent new product introductions, evolving industry standards and changing customer needs. There can be no assurance that NDC will be successful in developing and marketing these new products and services or that Source's current or new products and services will adequately meet the quickly changing demands of Source's pharmaceutical company customers. In addition, in order to meet its customers demands, Source has undertaken a number of development projects, including efforts to update its core mainframe-based products. Because it is generally not possible to predict the time required and costs involved in reaching certain research, development and engineering objectives, estimated product development schedules could require extensions. NDC believes that the future success of the Source business will depend in large part 25 on its ability to maintain and enhance its current product and service offerings and to continually develop and introduce new products and services that will keep pace with technological advances and satisfy evolving customer requirements. Further, there can be no assurance that NDC will not experience difficulties that could delay or prevent the successful development, introduction and marketing of these products and services. If NDC is unable to develop and introduce new products and services in a timely manner, or if a new or updated product does not achieve market acceptance, NDC's financial condition and results of operations could be materially adversely affected. FORWARD-LOOKING STATEMENTS When used in this Proxy Statement/Prospectus and elsewhere by management or NDC from time to time, the words "believes," "anticipates," "expects" and similar expressions are intended to identify forward-looking statements concerning NDC's operations, economic performance and financial condition, including in particular, the likelihood of NDC's success in developing and expanding its business. These statements are based on a number of assumptions and estimates which are inherently subject to significant uncertainties and contingencies, many of which are beyond the control of NDC, and reflect future business decisions which are subject to change. A variety of factors could cause actual results to differ materially from those anticipated in NDC's forward-looking statements, some of which include competition in the market for NDC's services, continued expansion of NDC's processing and payment systems markets, successfully completing and integrating acquisitions in existing and new markets and other risk factors that are discussed herein and from time to time in other NDC reports and other filings with the Commission. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date they are made. NDC undertakes no obligations to publicly release the results of any revisions to such forward- looking statements that may be made to reflect events or circumstances after the date hereof, or thereof, as the case may be, or to reflect the occurrence of unanticipated events. 26 GENERAL INFORMATION SPECIAL MEETING This Proxy Statement/Prospectus is being furnished by Source to its stockholders in connection with the Special Meeting of the stockholders of Source to be held at 9:30 a.m., local time, on , 1997, at The Lotos Club, 5 East 66th Street, New York, New York, and at any adjournments and postponements thereof, to consider and vote upon a proposal to adopt the Merger Agreement and consummation of the transactions contemplated therein, and to transact such other business as may properly come before the Special Meeting. This document is also being furnished by NDC to Source stockholders as a prospectus in connection with the issuance by NDC of shares of NDC Common Stock upon consummation of the Merger. The Merger Agreement provides for a transaction whereby a wholly-owned subsidiary of NDC will merge with and into Source, with Source as the surviving corporation of the Merger becoming a wholly-owned subsidiary of NDC. At the Effective Time, each share of issued and outstanding Source Capital Stock (excluding shares held by Source or any of its subsidiaries or by NDC or any of its subsidiaries, and excluding shares as to which dissenters' rights are perfected) shall cease to be outstanding and shall be converted into and exchanged for the right to receive shares of NDC Common Stock and/or cash. Pursuant to the NDC Rights Agreement, each share of NDC Common Stock issued in connection with the Merger upon conversion of Source Common Stock shall be accompanied by an NDC Right. See "The Merger--Exchange Ratios" and "Certain Differences in the Rights of NDC and Source Stockholders." If the Merger Agreement is adopted at the Special Meeting, all required governmental and other consents and approvals are obtained, and all of the other conditions to the obligations of the parties to consummate the Merger are either satisfied or waived (as permitted), the Merger will be consummated. See "The Merger--Conditions to Consummation." RECORD DATE The Source Board of Directors has fixed the close of business on November 3, 1997, as the record date for determining the Source stockholders entitled to receive notice of and to vote at the Special Meeting. Only holders of record of Source Capital Stock as of the Record Date are entitled to notice of and to vote at the Special Meeting. As of the Record Date, there were 5,800,193 shares of Source Common Stock issued and outstanding and held by 143 holders of record and 1,041,667 shares of Source Preferred Stock issued and outstanding and held by 52 holders of record. Holders of Source Common Stock are entitled to one vote on each matter considered and voted on at the Special Meeting for each share of Source Common Stock held of record at the close of business on the Record Date. Holders of Source Preferred Stock are entitled to one vote on each matter considered and voted on at the Special Meeting for each share of Source Preferred Stock held of record at the close of business on the Record Date. The presence, in person or by properly executed proxy, of the holders of a majority of the outstanding shares of Source Common Stock entitled to vote at the Special Meeting is necessary to constitute a quorum of the holders of Source Common Stock at the Special Meeting. The presence, in person or by properly executed proxy, of the holders of a majority of the outstanding shares of Source Preferred Stock entitled to vote at the Special Meeting is necessary to constitute a quorum of the holders of Source Preferred Stock at the Special Meeting. Abstentions will be counted as shares present for purposes of determining the presence of a quorum but will not be counted as votes cast for purposes of determining whether a proposal has received sufficient votes for adoption. Consequently, abstentions will have the effect of a vote against the Merger. VOTES REQUIRED Adoption of the Merger Agreement and consummation of the transactions contemplated therein requires the presence of a quorum and the affirmative vote of: (i) the holders of a majority of the outstanding shares of Source Common Stock and Source Preferred Stock entitled to vote thereon at the Special Meeting, voting as a single class, and (ii) the holders of a majority of the outstanding shares of Source Preferred Stock entitled to vote 27 thereon at the Special Meeting. Abstentions will have the effect of a vote against the Merger. The holders of approximately 98% of the outstanding shares of Source Preferred Stock have agreed to vote all of such shares in favor of the adoption of the Merger Agreement. See "The Merger--Voting Agreement." As of the Record Date, Source directors and executive officers, and their affiliates, beneficially owned approximately 74.9% of the outstanding shares of Source Common Stock entitled to vote at the Special Meeting and 50% of the outstanding shares of Source Preferred Stock entitled to vote at the Special Meeting. As of the Record Date, NDC and its directors and executive officers, and their affiliates, held no shares of Source Common Stock or Source Preferred Stock. See "The Merger--Voting Agreement." RECOMMENDATION OF SOURCE'S BOARD OF DIRECTORS For the reasons described below, the Board of Directors of Source has unanimously adopted the Merger Agreement, believes the Merger is in the best interests of Source and its stockholders, and unanimously recommends that stockholders of Source vote FOR adoption of the Merger Agreement and the consummation of the transactions contemplated therein. See "The Merger-- Reasons for the Merger." THE MERGER The following information describes certain information pertaining to the Merger. This description does not purport to be complete and is qualified in its entirely by reference to the Annexes hereto, including the Merger Agreement, a copy of which is set forth in Annex A to this Proxy Statement/Prospectus and is incorporated herein by reference. All stockholders are urged to read the Annexes in their entirely. GENERAL The Merger Agreement provides that Sub will merge with and into Source, which shall be the surviving corporation of the Merger and, as a result thereof, become a wholly-owned subsidiary of NDC. At the time the Merger becomes effective, each outstanding share of Source Capital Stock (excluding shares held by Source or any of its subsidiaries or by NDC or any of its subsidiaries, and excluding shares of Source Capital Stock as to which dissenter's rights are perfected) shall cease to be outstanding and shall be converted into and exchanged for the right to receive shares of NDC Common Stock and/or cash. Pursuant to the NDC Rights Agreement, each share of NDC Common Stock issued in connection with the Merger upon conversion of the Source Common Stock shall be accompanied by an NDC Right. If the Merger Agreement is adopted at the Special Meeting, all required governmental and other consents and approvals are obtained, and all other conditions of the obligations of the parties to consummate the Merger are either satisfied or waived (as permitted), the Merger will be consummated. BACKGROUND OF THE MERGER Source was formed in April 1996 as a spin-off from Walsh International, Inc. ("Walsh") immediately prior to Walsh's initial public offering. In May 1996, the Board of Directors of Source began considering a strategic direction for Source with a view to maximizing shareholder value and creating avenues to liquidity for Source stockholders. In May, June and July 1996, Source and its investment bankers had preliminary discussions regarding business combinations with several potentially interested parties. In addition, during this period the Source Board of Directors informally notified PMSI that it was evaluating strategic alternatives. From a business and strategic perspective, Source management believed that the acquisition of Source by PMSI might have been attractive given the significant business relationships between the two parties. In 1991, PMSI and Walsh, as the predecessor of Source, had entered into an operating venture to more fully exploit the databases produced by Source. More recently, PMSI and Source had also reached agreement in principle for PMSI's profit participation in Source's 28 efforts to build and commercialize similar databases in major European markets. After some negotiations, however, Source management was informed that PMSI was unwilling to pay a purchase price that the Source Board of Directors would accept. During the first half of calendar 1996, Source and NDC, which has been a significant data supplier to Source since inception of the operating venture between Source and PMSI, commenced discussions with regard to creating a new information service to deliver daily physician-level prescription data captured from NDC's health care transaction processing network to Source clients in the United States. During the course of these discussions, NDC management suggested that, due to the complementary nature of the businesses, there be a senior management meeting of all three companies to explore the potential for further cooperation. Commencing in November 1996, senior management from NDC, PMSI and Source met several times to explore the potential synergies among their businesses. While a possible transaction in which NDC would acquire all of PMSI and Source was discussed, NDC did not submit an acquisition proposal to PMSI and Source. NDC expressed the view that, since it had no significant operations outside the United States, it believed that the greatest benefits would be derived from cooperative ventures with Source's United States operations, the OTC Business and NDC's health care transaction processing network, all based and operating solely in the United States. In May 1997, NDC expressed an interest in acquiring these parts of the PMSI and Source businesses. NDC's proposal contemplated the acquisition by NDC of the OTC Business and all the outstanding capital stock of Source, subject to Source's divestiture of its interest in Source Europe. The Source Board of Directors determined that the transaction would substantially achieve its strategic goals. The Source Board also concluded that the transfer of Source Europe to PMSI was the best alternative to achieve satisfaction of the divestiture condition in NDC's proposal within the timeframe of such proposal. In exploring other possible business combinations, Source had not received any proposals to acquire Source Europe, which is still in the developmental stage. The Source Board recognized that the development and commercialization of Source Europe's data products and services would require capital beyond Source's current resources and that successful introduction of such products and services in various European markets would be subject to significant uncertainties. Source believed that the acquisition of Source Europe would be attractive to PMSI because it would complement PMSI's existing European businesses and would thereby enhance PMSI's future market position in Europe. In June 1997, NDC, PMSI and Source commenced negotiations and reached preliminary agreement for PMSI to acquire 100% of Source Europe and for NDC to acquire 100% of Source (including PMSI's interest in Source) together with the OTC Business, for a total purchase price payable to PMSI and the stockholders of Source consisting of $153 million, payable 75% in registered shares of NDC Common Stock and 25% in cash. Source appointed its investment bankers to negotiate on its behalf both the allocation between Source and PMSI of the total NDC consideration to be received in the Stock Purchase and the Merger and the terms of the transfer from Source to PMSI of Source Europe. PMSI was represented in these negotiations by its own investment bankers. To date, Source has made significant investments in Source Europe, which include researching the market potential and entry strategies, entering into contracts with data vendors, developing databases, gaining regulatory approval in certain markets, building infrastructure and entering into service contracts with pharmaceutical companies. From inception on January 1, 1994, through June 30, 1997, Source Europe incurred an aggregate net loss of $42 million and had revenues of $407,000, which were recognized in fiscal 1997. The Source Board believes that the creation of significant value by Source Europe is subject to a number of factors, including receipt of all required regulatory approvals, the availability of adequate capital resources to complete development of Source Europe's products and services and the successful introduction of such products and services in various national markets. In negotiating the terms of the transfer of Source Europe to PMSI, Source acknowledged that the current value of Source Europe is inherently speculative, given the risks associated with such business, and that PMSI 29 would be assuming significant risks in agreeing to complete the development and commercialization of Source Europe. Source also recognized that, if such risks could be overcome, the projections of Source Europe's cash flows prepared by Source's management would indicate a significantly higher discounted present value than the negotiated terms of the Source Divestiture Agreement, which reflected the risks to achieving successful commercialization. Under all the circumstances, including the desire of Source's Board to take advantage of NDC's attractive proposal to acquire the rest of Source, the need for additional resources to complete the development and commercialization of Source Europe and the absence of any other offers to acquire Source Europe, the Source Board concluded that the terms of the transfer of Source Europe were fair to Source stockholders. Through July and August 1997, Source, PMSI and NDC continued to negotiate the final terms of the Stock Purchase and the Merger. These negotiations did not result in any material changes in the economic terms of the Stock Purchase or the Merger, however, the negotiations did cover certain other terms of the Stock Purchase Agreement and the Merger Agreement, including the scope of representations and warranties, the scope and duration of indemnities and related escrow arrangements and the principal terms of ancillary agreements between the parties. On August 20, 1997, the Stock Purchase Agreement, the Source Divestiture Agreement and the Merger Agreement were executed. REASONS FOR THE MERGER The Source Board of Directors, after consideration of relevant business, financial, legal and market factors, approved the Merger Agreement. Source's Board did not assign any relative or specific weight to the factors considered. The factors considered included: (i) the expressed desire for liquidity of stockholders holding a majority of the outstanding Source Capital Stock; (ii) the prospective strategic benefits to the Source business of a combination with an acquiror that could facilitate expansion into other aspects of the health care information services industry; (iii) the fact that a variety of other strategic options had been explored since the inception of Source, without locating a strategic partner or buyer willing to offer the potential value offered in the Merger; (iv) the opinions, analyses and presentations of Montgomery Securities, Source's investment bankers; (v) the structure of the Merger may permit holders of Source Capital Stock to have their shares converted into NDC Common Stock on a tax free basis; and (vi) the financial condition, cash flows and results of operations of Source and NDC, both on an historical and a prospective basis. THE BOARD OF DIRECTORS OF SOURCE UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" ADOPTION OF THE MERGER AGREEMENT AND CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED THEREIN. The NDC Board of Directors, after consideration of relevant business, financial, legal and market factors, approved the Merger Agreement. The NDC Board of Directors did not assign any relative or specific weight to the factors considered. The factors considered included: (i) the prospective strategic benefits to NDC of a combination with Source and PMSI Database which could facilitate the growth of NDC's health care information services business; (ii) the potential to utilize certain in-process research and development projects of Source, including significant revisions and additions to the architecture and functionality of Source's systems, to build upon certain of NDC's own projects; and (iii) the potential costs and delays involved in independently developing service offerings similar to those currently provided and those under development by Source and PMSI Database; (iv) the financial condition, cash flows and results of operations of Source and NDC, both on an historical and a prospective basis. 30 EXCHANGE RATIOS The Merger Agreement provides that upon consummation of the Merger: (a) Subject to a working capital adjustment (discussed below), each outstanding share of Source Common Stock (excluding shares held by Source or any of its subsidiaries or by NDC or any of its subsidiaries, and excluding shares of Source Common Stock as to which dissenters' rights are perfected) issued and outstanding immediately prior to the Effective Time shall cease to be outstanding and shall be converted into and exchanged for the right to receive the following: (i) the amount, if any, equal to the quotient of (A) the Aggregate Cash Amount less the Preferred Stock Merger Consideration, and less the Transaction Expenses, and (B) the total number of shares of Source Common Stock outstanding as of the Closing Date; (ii) that fraction of a share of NDC Common Stock equal to the quotient of (A) the Payment Shares less the Option Shares, and (B) the total number of shares of Source Common Stock outstanding as of the Closing Date; provided, however, if the sum of the Preferred Stock Merger Consideration and the Transaction Expenses exceeds the Aggregate Cash Amount, then the Payment Shares will be reduced by that number of shares of NDC Common Stock equal to the Excess Expense divided by the Average Closing Price, as of the Closing Date; and (iii) that fraction of a share of NDC Common Stock equal to the quotient of the Stock Escrow divided by the total number of shares of Source Common Stock outstanding as of the Closing Date. The Stock Escrow will be utilized for working capital adjustments and for indemnification claims by NDC, all pursuant to the terms of the Merger Agreement and the Escrow Agreement. At the Closing Date, Source shall prepare and deliver to NDC a schedule indicating the Transaction Expenses incurred but unpaid as of the Closing Date including, without limitation, all expenses incurred in connection with Source's termination of certain employment agreements and an executive pension plan. In addition, also at the Closing Date, Source shall have secured the cancellation of all outstanding options and warrants to purchase shares of Source Common Stock and shall provide to NDC a schedule of the Option Shares payable to the holders of such options and warrants in consideration of such cancellation. Pursuant to the NDC Rights Agreement, each share of NDC Common Stock issued in connection with the Merger upon conversion of Source Common Stock shall be accompanied by an NDC Right. Based on the market price of NDC Common Stock on , 1997 and an estimate of the Transaction Expenses on such date, each outstanding share of Source Common Stock would receive $ and shares of NDC Common Stock. These amounts may change, however, at the Closing Date since the Transaction Expenses and the Option Shares will be determined on or immediately prior to the Closing Date. In addition, the Preferred Stock Merger Consideration is subject to adjustment, in certain circumstances, on or prior to the Closing Date. See "Certain Differences in the Rights of NDC and Source Stockholders." (b) Each share of Source Preferred Stock (excluding shares held by Source or any of its subsidiaries or by NDC or any of its subsidiaries, and excluding shares of Source Preferred Stock as to which dissenters' rights are perfected) issued and outstanding immediately prior to the Effective Time shall cease to be outstanding and shall be converted and exchanged for the right to receive an amount equal to the Preferred Stock Merger Consideration. The amount of cash and shares of NDC Common Stock to be paid to the holders of Source Common Stock was determined based on a per share value for the NDC Common Stock of $43.875, the market price for the NDC Common Stock at the time NDC, Source and PMSI commenced negotiations. See "The Merger--Background of the Merger." COMMON EXCHANGE RATIO ADJUSTMENT If, at the close of trading on the Determination Date, the Average Closing Price shall be greater than the Upper Threshold Price, the Common Exchange Ratios shall each be adjusted to equal that fraction of a share of NDC Common Stock (rounded to the nearest ten thousandth of a share) obtained by dividing the product of the Common Base Exchange Ratio or the Common Escrow Exchange Ratio, as the case may be, and the Upper Threshold Price by the Average Closing Price at the Determination Date. If the Average Closing Price on the 31 Determination Date shall be less than the Lower Threshold Price, Source shall have the right to refuse to consummate the Merger provided that Source shall have given written notice of such refusal to NDC not later than two trading days following the Determination Date. During the five-day period commencing with its receipt of such notice, NDC shall have the option, in its sole discretion, to elect to revise the Common Exchange Ratios to equal that fraction of a share of NDC Common Stock (rounded to the nearest ten thousandth of a share) obtained by dividing the product of the Common Base Exchange Ratio or the Common Escrow Exchange Ratio, as the case may be, and the Lower Threshold Price by the Average Closing Price at the Determination Date. If NDC makes the election contemplated by the preceding sentence within such five-day period, it shall give prompt written notice to Source of such election and the revised Common Exchange Ratios, whereupon the Merger Agreement shall remain in effect in accordance with its terms (except that the Common Exchange Ratios shall have been so modified). If the Lower Threshold Price is not reached, the Board of Directors of Source will take such action as is required by law and its fiduciary obligations, including, if appropriate, obtaining the consent of the Source stockholders to proceed with the Merger. WORKING CAPITAL ADJUSTMENT The Stock Escrow shall be adjusted in the manner described below: Preliminary Balance Sheet. Source will cause to be prepared and delivered to NDC the Preliminary Balance Sheet and a certificate based on such Preliminary Balance Sheet setting forth Source's calculation of Estimated Working Capital, Estimated Current Assets and Estimated Current Liabilities. The Preliminary Balance Sheet shall include and fairly present the consolidated financial position of Source and its subsidiaries as of the close of business on the date of the Preliminary Balance Sheet in accordance with GAAP applied on a basis consistent with those used in the preparation of the Source Balance Sheet. NDC shall have five business days from the receipt of the Preliminary Balance Sheet and the calculation of Estimated Working Capital, Estimated Current Assets and Estimated Current Liabilities to review such statement and calculations and following such review such statements and calculations shall be final and binding. If Estimated Current Assets are less than the product of (i) 0.9416 times (ii) Estimated Current Liabilities as of the date of the Preliminary Balance Sheet, the Stock Escrow payable by NDC shall be decreased by the number of shares of NDC Common Stock equal to the Estimated Working Capital Adjustment divided by the Average Closing Price as of the Closing Date; provided, however, in the event this reduction of the Stock Escrow exceeds 113,960 shares, the Payment Shares shall then be decreased similarly in an amount equal to such excess. Closing Balance Sheet. As promptly as practicable, but not later than 30 days after the Closing Date, NDC will cause to be prepared and delivered to the Stockholder Representative the Closing Balance Sheet setting forth NDC's calculation of Closing Working Capital, Closing Current Assets and Closing Current Liabilities. The Closing Balance Sheet shall include and fairly present the consolidated financial position of Source and its subsidiaries as of the close of business on the Closing Date in accordance with GAAP applied on a basis consistent with those used in the preparation of the Source Balance Sheet. The Closing Balance Sheet and the calculation of Closing Working Capital, Closing Current Assets and Closing Current Liabilities shall be deemed final upon the earliest of (i) the date on which NDC and the Stockholder Representative jointly agree that such documents are final, (ii) the 30th day after delivery of such documents, if the Stockholder Representative has not delivered a notice to expressing disagreement with such calculations and setting forth its calculation of such amount(s), and (iii) the date on which all disputes relating to such statements and calculations between the parties are resolved. If the Stockholder Representative shall deliver a notice of disagreement, the Stockholder Representative and NDC shall, during the 30 days following such delivery, use their reasonable efforts to reach agreement on the Disputed Amounts. If, during such period, the Stockholder Representative and NDC are unable to reach such agreement, they shall promptly thereafter cause Price Waterhouse LLP (or if said firm shall be unwilling to act thereunder, such other independent accountants of nationally recognized standing reasonably satisfactory to NDC and the Stockholder Representative), promptly to review the Merger Agreement and any other documents 32 necessary to calculate the Disputed Amounts (including all work papers of the parties used in calculating the Disputed Amounts) and such accountants shall then deliver a report to NDC and the Stockholder Representative setting forth their calculations which shall be final and binding. If Final Current Assets are less than the product of (i) 0.9416 times (ii) Final Current Liabilities, the Stockholders shall pay to NDC the amount of the Final Working Capital Deficit out of the Stock Escrow in the manner provided in the Escrow Agreement. If Final Current Assets are greater than the product of (i) 0.9416 times (ii) Final Current Liabilities, NDC shall pay to the escrow agent, to be held in accordance with the Escrow Agreement, that number of shares of NDC Common Stock equal to the quotient of the Final Working Capital Surplus divided by the Average Closing Price as of the date Final Working Capital was determined. Allocation with PMSI. NDC, Source and PMSI have agreed to the following adjustment in order to properly allocate the working capital adjustment based on their respective Closing Balance Sheets. If Total Current Assets are less than the product of 0.9975 and Total Current Liabilities, then the Stockholders shall pay to NDC the Current Asset Allocation Amount out of the Stock Escrow in the manner provided in the Escrow Agreement. If Total Current Assets are greater than the product of 0.9975 and Total Current Liabilities, then NDC shall pay to the Stockholders pursuant to the instructions of the Stockholder Representative that number of shares of NDC Common Stock equal to the quotient of the Current Asset Allocation Amount and the Average Closing Price as of the date Final Working Capital was determined. For purposes of any adjustments based on the Closing Balance Sheet, the parties shall take into account any adjustment made at closing pursuant to the Preliminary Balance Sheet. INDEMNIFICATION Pursuant to the Merger Agreement, the Stockholders jointly and severally agree to indemnify, defend, and hold harmless the Indemnitees, from, against, for and in respect of any and all losses asserted against, or paid, suffered or incurred by, an Indemnitee and resulting from, based upon, or arising out of: (a) the inaccuracy, untruth, incompleteness or breach of any representation or warranty of any Stockholder or Source contained in or made pursuant to the Merger Agreement or in any certificate, schedule, or exhibit furnished by the Stockholders or Source in connection therewith; (b) a breach of or failure to perform any covenant or agreement of the Stockholders or Source made in the Merger Agreement; (c) any and all taxes arising out of or associated with the Divestiture; (d) any and all taxes arising out of or associated with certain sales by Source; or (e) any and all losses relating to certain litigation ongoing as of the date of the Merger Agreement. The Stockholders will have no liability to the Indemnitees under or in connection with a breach of any of the representations, warranties, covenants or agreements made or to be performed by the Stockholders or Source contained in the Merger Agreement unless written notice asserting an indemnification claim based thereon is given to the Stockholder Representative prior to August 31, 1999. The Stockholders shall have no liability with respect to the matters described above until the total of all losses with respect thereto exceeds $200,000 in which event the Stockholders shall be obligated to indemnify the Indemnitees for all such losses; provided, however, that each individual claim of $10,000 or less shall not be indemnifiable, and shall not be included in determining whether the $200,000 threshold has been reached. In no event shall the aggregate liability of the Stockholders exceed the lesser of (i) the aggregate value of the Indemnification Escrow Amount, and (ii) $20,000,000. All disputes arising under the indemnification provisions of the Merger Agreement (other than claims in equity) shall be resolved by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association. 33 ESCROW AGREEMENT Pursuant to the terms of the Merger Agreement, the Stock Escrow (455,840 shares of NDC Common Stock decreased by the adjustment, if any, based on the Preliminary Balance Sheet discussed above), will be distributed to and will be held by the escrow agent pursuant to the terms of the Escrow Agreement, a copy of which is attached to this Proxy Statement/Prospectus as Annex C. Working Capital Escrow. The Working Capital Escrow Amount (a total of 113,960 of the Stock Escrow shares, less any shares paid to NDC as the result of an adjustment based on the Preliminary Balance Sheet), are reserved to cover an adjustment, if any, based on the Closing Balance Sheet. The Stockholder Representative, or the Stockholders with respect to their individual percentage interest, may direct the escrow agent to sell, from time to time, any or all of the shares of NDC Common Stock in the Working Capital Escrow Amount at such prices as are commercially reasonable at the time of sale. Any and all cash proceeds from the sale of such shares shall remain in escrow as part of the Working Capital Escrow Amount, except that at the end of each calendar month, if the aggregate value of the Working Capital Escrow Amount exceeds 133% of the aggregate value of the Stock Escrow as of the Closing Date, the Escrow Agent shall distribute to the Stockholders that amount in cash or shares of NDC Common Stock equal to their respective percentage interest in such surplus. If, prior to the Distribution Date with respect to the Working Capital Escrow Amount, NDC shall be entitled to an adjustment based on the Closing Balance Sheet, the escrow agent shall distribute to NDC from the Working Capital Escrow Amount an amount in cash, in immediately available funds, equal to such adjustment claim, and, if the Working Capital Escrow Amount does not contain any cash, or contains an amount of cash insufficient to satisfy the claim, then the escrow agent shall distribute to NDC from the Working Capital Escrow Amount that number of shares of NDC Common Stock equal to the quotient (rounded to the next highest whole number) obtained by dividing the amount of the claim not paid in cash by the Average Closing Price as of the date Final Working Capital was determined. If the adjustment based on the Closing Balance Sheet is pending as of the Distribution Date with respect to the Working Capital Escrow Amount, the escrow agent shall retain an amount equal to the disputed claim amount and promptly deliver to the Stockholders a distribution of cash, if any, in immediately available funds, and shares of NDC Common Stock from the Working Capital Escrow Amount, equal to any remaining amounts in the Working Capital Escrow Amount. The disputed amount shall be paid to NDC or the Stockholders, as the case may be, upon the final resolution as agreed by NDC and the Stockholder Representative in writing of the amount of the adjustment claim. Indemnification Escrow. The Indemnification Escrow Amount (a total of 341,880 of the Stock Escrow shares) are reserved to cover claims by NDC based on the indemnification provisions of the Merger Agreement. The Stockholder Representative, or the Stockholders with respect to their individual percentage interest, may direct the escrow agent to sell, from time to time, any or all of the shares of NDC Common Stock in the Indemnification Escrow Amount at such prices as are commercially reasonable at the time of sale. Any and all cash proceeds from the sale of such shares shall remain in escrow as part of the Indemnification Escrow Amount, except that at the end of each calendar month, if the aggregate value of the Indemnification Escrow Amount exceeds $20,000,000, the escrow agent shall distribute to the Stockholders that amount in cash or shares of NDC Common Stock equal to their respective percentage interest in such surplus. If, prior to the Distribution Date with respect to the Indemnification Escrow Amount, NDC shall be entitled to a payment based on an indemnification claim, the escrow agent shall distribute to NDC from the Indemnification Escrow Amount an amount in cash, in immediately available funds, equal to such claim, and, if the Indemnification Escrow Amount does not contain any cash, or contains an amount of cash insufficient to satisfy the claim, then the escrow agent shall distribute to NDC from the Indemnification Escrow Amount that number of shares of NDC Common Stock equal to the quotient (rounded to the next highest whole number) obtained by dividing the amount of the claim not paid in cash by the Average Closing Price as of the date the notice of claim was received by the escrow agent. 34 If an indemnification claim is pending as of the Distribution Date with respect to the Indemnification Escrow Amount, the escrow agent shall retain an amount equal to the disputed claim amount and promptly deliver to the Stockholders a distribution of cash, if any, in immediately available funds, and shares of NDC Common Stock from the Indemnification Escrow Amount, equal to any remaining amounts in the Indemnification Escrow Amount. The disputed amount shall be paid to NDC or the Stockholders, as the case may be, upon the final resolution as agreed by NDC and the Stockholder Representative in writing of the amount of the outstanding claim. General. Any and all cash dividends or other cash income with respect to the Stock Escrow shall be paid into and remain in escrow and shall be available for purposes of adjustments or distributions. Each Stockholder shall have the right to direct the escrow agent in writing as to the exercise of voting rights with respect to shares in the Stock Escrow held by the escrow agent on behalf of such Stockholder, and the escrow agent shall comply with any such directions if received in a timely manner. In the absence of such directions, the escrow agent shall not vote any such shares in the Stock Escrow. The escrow agent shall invest the cash amount, if any, included in the Working Capital and Indemnification Escrow Amounts as directed by the Stockholder Representative or the Stockholders, provided that should the Stockholder Representative or the Stockholders fail to so direct the escrow agent, NDC shall be authorized to so direct the escrow agent, and, provided further that such investments shall be limited to (i) direct obligations of the United States of America, (ii) obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of principal and interest, (iii) commercial paper rated of the highest quality by Moody's or S&P, and (iv) certificates of deposit issued by a commercial bank (which may be the escrow agent or any affiliate of the escrow agent) whose long-term debt obligations are rated at least A2 by Moody's or at least A by S&P, in each case having a maturity not in excess of 90 days, or a money market fund that invests exclusively in said investments. THE STOCKHOLDER REPRESENTATIVE The Stockholder Representative shall mean a committee comprised of Messrs. Dennis Turner, Handel Evans and Patrick Welsh. Mr. Turner is the Chief Executive Officer and a director of Source. Mr. Evans is the Chairman of the Board of Directors of Source. Mr. Welsh is a director of Source and a general partner of the respective sole general partners of several affiliated private investment funds, including Welsh, Carson, Anderson & Stowe V, L.P. and Welsh, Carson, Anderson & Stowe IV, L.P., that are stockholders of Source. The Stockholder Representative shall have the responsibility and authority to enforce any adjustment based on the Closing Balance Sheet, the indemnification provisions of the Merger Agreement, and the terms and conditions of the Escrow Agreement, all on behalf of the Stockholders. FRACTIONAL SHARES Pursuant to the terms of the Merger Agreement, each holder of shares of Source Common Stock exchanged pursuant to the Merger, who would otherwise have been entitled to receive a fraction of a share of NDC Common Stock shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of NDC Common Stock multiplied by the closing price per share of NDC Common Stock as reported on the NYSE on the last trading day immediately preceding the Effective Time. No such holder will be entitled to dividends, voting rights, or any other rights as a stockholder in respect of any fractional shares. TERMINATION OF STOCK OPTIONS The Merger Agreement provides that, at the Closing Date, Source shall have secured the cancellation of all outstanding options and warrants to purchase shares of Source Common Stock and shall provide to NDC a schedule of the Option Shares payable to the holders of such options and warrants in consideration of such cancellation. EFFECTIVE TIME AND CLOSING DATE If the Merger Agreement is adopted by the requisite votes of Source stockholders, and all other required governmental and other consents and approvals are received, and if the other conditions to the obligations of the 35 parties to consummate the Merger are satisfied or waived (as permitted), the Merger will be consummated and effected on the date and at the time a Certificate of Merger, reflecting the Merger, becomes effective with the Secretary of State of the State of Delaware. NDC and Source have mutually agreed to use their reasonable efforts to cause the Effective Time to occur on the first business day following the last to occur of: (i) the effective date (including expiration of any applicable waiting period) of the last required approval or clearance of any regulatory authority having authority over and approving or exempting the Merger, (ii) the date on which the stockholders of Source approve the Merger Agreement, and (iii) the date on which the stockholders of PMSI approve the Stock Purchase Agreement. Assuming satisfaction of all conditions to consummation of the Merger, the Merger is expected to be made effective during the fourth quarter of calendar 1997. Either NDC or Source may terminate the Merger Agreement if the Merger has not been consummated by January 31, 1998. The closing of the Merger shall take place on the date the Effective Time occurs or such other date as the parties shall agree which NDC and Source anticipate will be not more than five business days following the Special Meeting. See "--Conditions to Consummation" and "--Amendment, Waiver, and Termination." DISTRIBUTION OF NDC CERTIFICATES Promptly after the Effective Time, NDC and Source shall cause the exchange agent selected by NDC to mail appropriate transmittal materials to each record holder of Source Common Stock and Source Preferred Stock for use in effecting the surrender and cancellation of those certificates in exchange for NDC Common Stock and/or cash (which shall specify that delivery shall be effected, and risk of loss and title to the certificates theretofore representing shares of Source Common Stock and Source Preferred Stock shall pass, only upon proper delivery of such certificates to the exchange agent by the former stockholders of Source). SOURCE STOCKHOLDERS SHOULD NOT SURRENDER THEIR CERTIFICATES FOR EXCHANGE UNTIL THEY RECEIVE SUCH LETTER OF TRANSMITTAL AND INSTRUCTIONS. After the Effective Time, each holder of shares of Source Common Stock and Source Preferred Stock (excluding shares held by Source or any of its subsidiaries or by NDC or any of its subsidiaries, and excluding shares as to which dissenters' rights are perfected) issued and outstanding at the Effective Time shall surrender the certificate or certificates representing such shares to the exchange agent, and the certificates thus surrendered will be canceled. Unless otherwise designated by a Source stockholder on the transmittal letter, certificates representing shares of NDC Common Stock and/or cash issued or deliverable to Source stockholders in connection with the Merger will be issued and delivered to the tendering Source stockholder at the address on record with Source. NDC shall not be obligated to deliver the consideration to which any former holder of Source Common Stock and Source Preferred Stock is entitled until such holder surrenders such holder's certificate or certificates representing such holder's shares for exchange. The certificate or certificates so surrendered shall be duly endorsed as the exchange agent may require. No party shall be liable to a holder of Source Common Stock and Source Preferred Stock for any property delivered in good faith to a public official pursuant to any applicable abandoned property law. After the Effective Time, holders of Source certificates will have no rights with respect to the shares of Source Common Stock and Source Preferred Stock represented thereby other than the right to surrender such certificates and receive in exchange therefor the shares of NDC Common Stock and/or cash to which such holders are entitled, as described above. In addition, no dividend or other distribution payable to holders of record of NDC Common Stock will be paid to the holder of any Source certificates until such holder surrenders such certificates for exchange as instructed. Subject to applicable law, upon surrender of the certificates, such holder will receive the certificates representing the shares of NDC Common Stock and/or cash issuable or deliverable upon the exchange or conversion of such shares of Source Common Stock and Source Preferred Stock, all withheld dividends or other distributions (without interest), and any withheld cash payments (without interest) to which such stockholder is entitled. If any certificate for NDC Common Stock is to be issued in a name other than that in which the Source certificate surrendered for exchange is issued, the Source certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer, and the person requesting such exchange shall affix any requisite stock transfer tax stamps to the certificates surrendered, shall provide funds for their purchase, or shall establish to the exchange agent's satisfaction that such taxes are not payable. 36 CERTAIN FEDERAL INCOME TAX CONSEQUENCES The following is a discussion of the material federal income tax consequences of the Merger. This discussion is based on the provisions of the Code, the United States Department of the Treasury Regulations thereunder and rulings and court decisions as of the date hereof, all of which are subject to change, possibly retroactive. The discussion is included for general information purposes only, applies only to Source stockholders, if any, who hold their stock as a capital asset, and may not apply to Source stockholders, if any, who received their stock upon the exercise of employee stock options or otherwise as compensation or have a special tax status. NDC and Source have not requested a ruling from the Service and neither party is obtaining a tax opinion from counsel regarding the qualification of the Merger as a tax-free reorganization within the meaning of Section 368(a) of the Code. It is intended that the Merger will qualify as a tax-free reorganization within the meaning of Section 368(a) of the Code. In order to so qualify, various factual matters must be true. Among other things, qualification as a tax-free reorganization is based on Source holding substantially all of its properties and substantially all of Sub's properties after the Merger. The Service takes the position that the "substantially all" requirement will be satisfied if at least 90% of the fair market value of the net assets and at least 70% of the fair market value of the gross assets held by both Source and Sub immediately prior to the Merger are held by Source after the Merger. Case authorities apply somewhat different criteria. The relative values of the assets exchanged in all of the Source and PMSI transactions is a factor in determining whether the "substantially all" test has been satisfied. As part of the transactions contemplated by the Merger Agreement, Source is disposing of its ownership in Source Europe to PMSI. In connection with the preparation of a fairness opinion rendered to a special committee of PMSI's Board, PMSI's investment bankers performed a discounted cash flow analysis of the various business segments to be sold and acquired by PMSI as contemplated by the Stock Purchase Agreement and the Source Divestiture Agreement, including such an analysis of certain projections of the cash flows of Source Europe over the next five years prepared by Source management. The projections assumed receipt of all required regulatory approvals, the availability of adequate capital resources to complete development of Source Europe's products and services and the successful introduction of such products in various national markets. The analysis assumed a sale of Source Europe at the end of the projected period at an assumed exit multiple and then discounted the cash flows to present value at an assumed discount factor. Utilizing this methodology results in a mid- range value for Source Europe of approximately $29 million. NDC and Source believe that this value is substantially in excess of the value of Source Europe at the time of disposition. In addition, NDC and Source believe that the negotiated terms of the transactions are the proper basis for analyzing the "substantially all" test. However, there can be no assurance that the Internal Revenue would not adopt a different valuation methodology or otherwise challenge compliance with the "substantially all" test. If Source does not hold substantially all of its assets, as well as substantially all of Sub's assets immediately after the Merger, or the Merger failed to qualify as a tax free reorganization for any other reason, then the exchange of Source Common Stock for NDC Common Stock will be a taxable sale of stock and Source stockholders will recognize gain or loss on the transaction. If the Merger is treated as a taxable sale of stock, Source stockholders will be taxed in the same manner as is described below. If the Merger is treated as a reorganization as defined in Section 368(a) of the Code, the following will be the material federal income tax consequences to the Source stockholders: (i) No gain or loss will be recognized for federal income tax purposes by Source stockholders upon the exchange of their shares of Source Common Stock for shares of NDC Common Stock. (ii) The basis of the shares of NDC Common Stock to be received by Source stockholders will be the same as the basis of the Source Common Stock surrendered in exchange therefor. (iii) The holding period of the NDC Common Stock to be received by Source stockholders will include the period during which the shares of Source Capital Stock surrendered in exchange therefor had been held, provided such shares were held by such stockholders as a capital asset at the Effective Time. (iv) The payment of cash in lieu of fractional shares of NDC Common Stock will be treated as if the fractional shares were issued as part of the exchange and then redeemed by NDC. These cash payments 37 will be treated as having been received as distributions in full payment in exchange for the fractional shares of NDC Common Stock redeemed as provided in Section 302(a) of the Code. Generally, any gain or loss recognized upon such exchange will be capital gain or loss, provided the fractional share would constitute a capital asset in the hands of the exchanging stockholder. (v) The payment of cash in respect of shares of Source Capital Stock as to which dissenters' rights are perfected will be subject to capital gains (loss) treatment. Holders of Source Preferred Stock who receive solely cash in exchange for their stock will be treated as having received such payments as distributions in redemption of their shares of such stock subject to the provisions and limitations of Section 302 of the Code. After such distribution, if a former Source stockholder neither owns capital stock nor is deemed to own capital stock under constructive ownership rules, the redemption will be a complete termination of interest and will be treated as a distribution in full payment in exchange for shares of such stock. Accordingly, such stockholder will recognize gain or loss measured by the difference between the amount of cash received and such stockholder's adjusted basis in the stock surrendered. Upon the sale or exchange of NDC Common Stock, a holder of such stock generally will recognize capital gain or loss equal to the difference between the amount of cash and the fair market value of any property received upon the sale or exchange and such holder's adjusted tax basis in the NDC Common Stock. Under recently enacted legislation, long-term capital gains recognized by certain non-corporate holders of NDC Common Stock generally will be subject to a maximum federal income tax rate of 20% if the shares sold or exchanged are held for more than 18 months, and to a maximum federal income tax rate of 28% if such shares are held for more than one year but are not held for more than 18 months. Tax consequences to dealers in NDC Common Stock, non-United States holders of NDC Common Stock or others who have a special tax status or to persons who received their shares through the exercise of employee stock options or otherwise as compensation may be different and such persons should consult their tax advisors as to the tax consequences of a sale or exchange of NDC Common Stock. IN CONSIDERING THIS TRANSACTION STOCKHOLDERS SHOULD UNDERSTAND WHILE THE COMPANY AND SOURCE BELIEVE THIS TRANSACTION WILL BE TREATED AS A TAX FREE REORGANIZATION THERE IS NO ASSURANCE THAT THIS TRANSACTION WILL BE SO TREATED. IT MAY BE TREATED AS A TAXABLE SALE OF STOCK RESULTING IN IMMEDIATE TAX LIABILITY. EACH HOLDER OF SOURCE CAPITAL STOCK IS URGED TO CONSULT SUCH HOLDER'S OWN TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE MERGER (INCLUDING THE APPLICATION AND EFFECT OF FOREIGN, STATE AND LOCAL INCOME AND OTHER TAX LAWS). MANAGEMENT AND OPERATIONS AFTER THE MERGER Source will be the surviving corporation resulting from the Merger and will become a wholly-owned subsidiary of NDC. The Merger Agreement provides that from and after the Effective Time, the Board of Directors of Source shall consist of the directors of Sub immediately prior to the Effective Time. The Merger Agreement further provides that the officers of Source in office immediately prior to the Effective Time, together with such additional persons as may be elected, shall serve as the officers of Source from and after the Effective Time in accordance with the bylaws of Source. It is not expected that consummation of the Merger will result in any change in the Board of Directors or management of NDC or any of its other subsidiaries. INTERESTS OF CERTAIN PERSONS IN THE MERGER Other than as described herein, no director or executive officer of NDC or Source, and no associate of any such person, has any substantial interest, direct or indirect, in the Merger, other than an interest arising from the ownership of Source Capital Stock, in which case the director or officer receives no extra or special benefit not shared on a pro rata basis by all other holders of Source Capital Stock. See "Source Informatics, Inc.--Security Ownership of Directors, Executive Officers and Principal Securityholders of Source." 38 Certain members of Source's management and Board of Directors may be deemed to have interests in the Merger in addition to their interests as stockholders of Source generally. In each case, the Board of Directors of Source either was aware of these factors or, with respect to interests that arose subsequent to the Merger Agreement, was aware of their potential, and considered them, among other matters, in approving the Merger Agreement and the transactions contemplated thereby. Indemnification. The Merger Agreement provides that NDC shall for a period of six years after the Effective Time indemnify the present and former directors and officers of Source or any of its subsidiaries to the full extent permitted under the Delaware General Corporation Law (the "DGCL") and by Source's Certificate of Incorporation and Bylaws, as in effect on the date of the Merger Agreement, with respect to matters occurring at or prior to the Effective Time except that as a condition to the consummation of the Merger, each director and officer of Source shall execute and deliver a waiver of all claims under such indemnification provisions arising out of the Divestiture and the allocation of the total consideration between Source with respect to the Merger and PMSI with respect to the Stock Purchase. NDC shall use its reasonable efforts to maintain Source's existing directors' and officers' liability insurance policy (or a policy providing at least comparable coverage) for a period of three years after the Effective Time of the Merger; provided, that NDC shall not be obligated to make aggregate premium payments in respect of such policy which exceed, for the portion relating to Source's directors and officers, 150% of the annual premium payments on Source's current policy. Prior to the Closing Date, NDC shall provide Source with a third-party estimate of the costs associated with maintaining such policies, which amount shall constitute a liability of Source and shall be included as a Transaction Expense. Change In Control And Severance Arrangements. Handel E. Evans and Dennis M.J. Turner, directors and the Chairman of the Board and the Chief Executive Officer, respectively, of Source, are also directors and the Chairman of the Board and the Chief Executive Officer, respectively, of PMSI. In addition, Patrick J. Welsh, a director of Source, is also a director of PMSI and is a general partner of the general partner of a significant stockholder of PMSI ("WCAS") and, along with certain of its affiliated entities, is also the largest stockholder of Source. Assuming consummation of the Stock Purchase, Messrs. Evans and Turner are each to receive annual bonuses from PMSI of $570,000. In determining these bonuses, PMSI's Organization and Compensation Committee considered the successful completion of the Stock Purchase, the Divestiture and the Merger. At the consummation of the Merger, the employment by Source of Messrs. Evans and Turner will be terminated and they will each receive termination payments (to be paid jointly by PMSI and Source) under their respective employment agreements with Source aggregating $1.2 million and $880,000, respectively, after which Mr. Evans will enter into an employment agreement with PMSI as its full-time Chairman of the Board and Mr. Turner will enter into an employment agreement with PMSI as its full-time Chief Executive Officer. In the event that either Source or PMSI do not have sufficient cash available to consummate the Stock Purchase and the Merger, including related expenses, Messrs. Evans and Turner have agreed to receive partial payment of their respective termination payments in the form of registered NDC Common Stock. In addition, the annual bonuses of four other executives of Source, including Warren J. Hauser, Vice President and Secretary of PMSI, aggregating $565,000, will reflect the successful completion of the Stock Purchase. Mr. Evans, and trusts for the benefit of his family, currently own an aggregate 247,856 shares of Source Common Stock (representing approximately 3.6% of the Source Capital Stock outstanding and entitled to vote on the Merger) and options to purchase an additional 201,250 shares of Source Common Stock, all of which are currently exercisable or become exercisable upon consummation of the Merger. In addition, Mr. Evans beneficially owns an aggregate 134,652 shares of PMSI common stock and options to purchase an additional 300,000 shares of PMSI common stock, 250,000 of which are currently exercisable. Mr. Turner, and trusts for the benefit of his family, currently own an aggregate 242,584 shares of Source Common Stock (representing approximately 3.5% of the Source Capital Stock outstanding and entitled to vote on the Merger) and options to purchase an additional 151,250 shares of Source Common Stock, all of which are currently exercisable or become exercisable upon consummation of the Merger. In addition, Mr. Turner 39 beneficially owns an aggregate 133,879 shares of PMSI common stock and options to purchase an additional 300,000 shares of PMSI common stock, 250,000 of which are currently exercisable. Mr. Welsh owns 26,550 shares of Source Common Stock (less than 1% of the Source Capital Stock outstanding and entitled to vote on the Merger) and may be deemed to own the aggregate 2,544,147 shares of Source Common Stock (or approximately 37.19% of the Source Capital Stock outstanding and entitled to vote on the Merger) owned by WCAS and certain of its affiliated entities. Mr. Welsh also owns options to purchase an aggregate 7,500 shares of Source Common Stock all of which will become exercisable upon consummation of the Merger. In addition, Mr. Welsh owns 15,733 shares of PMSI common stock and may be deemed to beneficially own an aggregate 746,315 shares of PMSI common stock, owned by WCAS and related entitles. Mr. Welsh also owns options to purchase an aggregate 24,000 shares of PMSI common stock, 16,000 of which are currently exercisable. Post-Acquisition Compensation and Benefits. The Merger Agreement provides that, after the Effective Time, NDC will provide generally to officers and employees of Source and its subsidiaries, employee benefits under employee benefit plans, on terms and conditions that, when taken as a whole, are substantially similar to those currently provided by NDC and its subsidiaries to their similarly situated officers and employees. For purposes of participation and vesting and benefit accrual (other than benefit accrual under retirement plans) under such employee benefit plans, service with Source or its subsidiaries prior to the Effective Time will be treated as service with NDC or its subsidiaries. Subject to certain exceptions set forth in the Merger Agreement, NDC will honor all employment, severance, consulting and other compensation contracts previously disclosed to NDC between Source or any of its subsidiaries and any current or former director, officer or employee, and all provisions for vested amounts earned or accrued through the Effective Time under Source's benefit plans. CONDITIONS TO CONSUMMATION The obligations of Source and NDC to consummate the Merger are subject to the satisfaction or waiver (to the extent permitted) of the following conditions: (i) the stockholders of Source shall have adopted the Merger Agreement and the consummation of the transactions contemplated thereby by the requisite votes; (ii) the required regulatory approvals and clearances described under "--Regulatory Approvals" shall have been received and shall be in full force and effect with all waiting periods required by law having expired, and no such regulatory approval shall be conditioned or restricted in a manner which would, in the reasonable judgment of the Board of Directors of NDC, so materially adversely affect the economic or business benefits of the transactions contemplated by the Merger Agreement that had NDC known of such condition it would not, in its reasonable judgment, have entered into the Merger Agreement; (iii) each party shall have received any required consents of third parties; (iv) the absence of any law or order or any action taken by any court, governmental, or regulatory authority prohibiting, restricting, or making illegal the consummation of the Merger; (v) the Registration Statement of which this Proxy Statement/Prospectus is a part shall have been declared effective by the Commission and shall not be subject to a stop order or any threatened stop order, and the shares of NDC Common Stock issuable in connection with the Merger shall have been qualified, registered or otherwise approved for exchange under the securities laws of the various states in which such qualification, registration or approval is required; (vi) the shares of NDC Common Stock issuable pursuant to the Merger shall have been approved for listing on the NYSE, subject to effective notice of issuance; (vii) the accuracy, as of the date of the Merger Agreement and as of the Effective Time, of the representations and warranties of the other party as set forth in the Merger Agreement; (viii) prior to the Effective Time, the other party shall have performed in all material respects all of the agreements, covenants, acts and undertakings to be performed by it pursuant to the Merger Agreement; and (ix) each party shall have received customary closing documents, including, without limitation, an opinion of the other party's counsel, dated the closing date, as to certain matters. In addition, the obligations of NDC to consummate the Merger are subject to the satisfaction or waiver (to the extent permitted) of the following further conditions: (i) each of Messrs. Brown, Campbell, Douglass, McAferty, Silverberg, Strimbu, and Weintraub, and Ms. Vaughn, all executive officers of Source who shall continue in agreed capacities following the Merger, shall have executed and delivered an employment 40 agreement on terms substantially consistent with those set forth in an exhibit to the Merger Agreement, (ii) Messrs. Evans and Turner shall have executed and delivered to NDC a noncompetition agreement substantially in form attached to the Merger Agreement, (iii) the Stock Purchase shall have been consummated substantially simultaneously with the Effective Time; (iv) the Divestiture shall have been consummated; (v) less than 10% of the holders of Source Preferred Stock or Source Common Stock shall have perfected their dissenter's rights, (vi) each of the directors and officers of Source shall have executed and delivered the indemnification waivers discussed above under "-- Indemnification," (vii) Source shall have been released from any and all obligations under the contracts associated with Source's European business which is part of the Divestiture, (viii) the cancellation by Source of all outstanding options and warrants; and (ix) the following related agreements shall have been executed and delivered: (a) Source European License Agreement--provides for a license by Source to PMSI the rights to use certain technology and the Source trademark in certain European countries; (b) European Services Agreement--Source and NDC will provide certain transitional services to PMSI to support the European operations Source is conveying to PMSI in the Divestiture; (c) Lease Assignment/Subleases--various agreements transferring leases to Source for office space it currently utilizes and providing a sublease of certain portions of such space to Walsh International Inc.; and (d) Scott-Levin Services Agreement--provides for the transfer of data and services between PMSI Scott-Levin Inc., a subsidiary of PMSI, and Source. No assurances can be provided as to when or if all of the conditions precedent to the Merger can or will be satisfied or waived by the appropriate party. As of the date of this Proxy Statement/Prospectus, the parties have no reason to believe that any of the conditions set forth above will not be satisfied. The conditions to consummation of the Merger may be waived, in whole or in part, to the extent permissible under applicable law, by the party for whose benefit the condition has been imposed, without the approval of the Source stockholders. See "--Amendment, Waiver, and Termination." REGULATORY APPROVALS The obligations of NDC and Source to perform under the Merger Agreement and consummate the Merger are subject to the consent of, filings and registrations with, and notifications to, all regulatory authorities required for consummation of the Merger having been obtained or made and being in full force and effect and the expiration of all waiting periods required by law. Furthermore, no consent from any regulatory authority which is necessary to consummate the Merger shall be conditioned or restricted in a manner which in the reasonable judgment of the Board of Directors of NDC would so materially adversely impact the economic or business benefits of the Merger that, had such condition or requirement been known, NDC would not, in its reasonable judgment, have entered into the Merger Agreement. Under the HSR Act and the rules promulgated thereunder by the Federal Trade Commission (the "FTC"), the Merger may not be consummated until notifications have been given and certain information has been furnished to the FTC and the Antitrust Division of the Department of Justice (the "Antitrust Division") and the applicable waiting period has expired or been terminated. NDC and Source filed notification and report forms under the HSR Act with the FTC and the Antitrust Division on October 7, 1997. The statutory waiting period under the HSR Act expired on November 7, 1997. At any time before or after consummation of the Merger, the Antitrust Division or the FTC could take such action under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the consummation of the Merger or seeking divestiture of substantial assets of NDC or Source. At any time before or after the Effective Time, and notwithstanding that the waiting period under the HSR Act has expired, any state could take such action under the antitrust laws as it deems necessary or desirable in the public interest. Such action could include seeking to enjoin the 41 consummation for the Merger or seeking divestiture of substantial assets of NDC or Source. Private parties may also seek to take legal action under the antitrust laws under certain circumstances. NDC and Source believe that the Merger can be effected in compliance with federal and state antitrust laws; however, there can be no assurance that a challenge to the consummation of the Merger on antitrust grounds will not be made or that, if such a challenge were made, NDC and Source would prevail or would not be required to accept certain adverse conditions in order to consummate the Merger. AMENDMENT, WAIVER AND TERMINATION To the extent permitted by law, Source and NDC, with the approval of their respective Boards of Directors, may amend the Merger Agreement by written agreement at any time without the approval of the stockholders of Source, provided that after the adoption of the Merger Agreement by the Stockholders, no amendment can be made that, pursuant to Section 251 of the DGCL, requires further approval by the Stockholders. Prior to or at the Effective Time, either Source or NDC, acting through its respective Board of Directors, chief executive officer or other authorized officer, may waive any default in the performance of any term of the Merger Agreement by the other party, may waive or extend the time for the fulfillment by the other party of any of its obligations under the Merger Agreement, and may waive any of the conditions precedent to the Merger Agreement, except any condition that, if not satisfied, would result in the violation of an applicable law or governmental regulation. The Merger Agreement may be terminated, and the Merger abandoned, at any time prior to the Effective Time (a) by the mutual consent of the Boards of Directors of Source and NDC (b) in the event of any inaccuracy of any representation or warranty of the other party contained in the Merger Agreement which cannot be or has not been cured within 30 days after giving written notice to the breaching party of such inaccuracy and which inaccuracy would provide the terminating party the ability to refuse to consummate the Merger under the applicable standards set forth in the Merger Agreement (provided that the terminating party is not then in breach of any representation or warranty contained in the Merger Agreement under the applicable standards set forth in the Merger Agreement or in material breach of any covenant or other agreement contained in the Merger Agreement), (c) in the event of a material breach by the other party of any covenant or agreement contained in the Merger Agreement which cannot be or has not been cured within 30 days after the giving of written notice to the breaching party of such breach (provided that the terminating party is not then in breach of any representation or warranty contained in the Merger Agreement under the applicable standards set forth in the Merger Agreement or in material breach of any covenant or other agreement contained in the Merger Agreement), (d) if any approval of any regulatory authority required for consummation of the Merger and the other transactions contemplated by the Merger Agreement has been denied by final nonappealable action, or if any action taken by such authority is not appealed within the time limit for appeal (provided that the terminating party is not then in breach of any representation or warranty contained in the Merger Agreement under the applicable standards set forth in the Merger Agreement or in material breach of any covenant or other agreement contained in the Merger Agreement), (e) the stockholders of Source fail to vote their approval of the matters submitted for the approval by such stockholders at the Special Meeting (provided that the terminating party is not then in breach of any representation or warranty contained in the Merger Agreement under the applicable standards set forth in the Merger Agreement or in material breach of any covenant or other agreement contained in the Merger Agreement), (f) if the Merger is not consummated by January 31, 1998, provided that the failure to consummate is not due to the breach by the party electing to terminate, or (g) if any of the conditions precedent to the obligations of such party to consummate the Merger cannot be satisfied, fulfilled, or waived by the appropriate party by January 31, 1998 (provided that the terminating party is not then in breach of any representation or warranty contained in the Merger Agreement under the applicable standards set forth in the Merger Agreement or in material breach of any covenant or other agreement contained in the Merger Agreement). See "--Expenses and Fees." 42 In addition, NDC may unilaterally terminate the Merger Agreement if the Source Board of Directors fails to reapprove or resolves not to affirm the Merger or recommends entering into a transaction other than the Merger involving a merger, share exchange, consolidation or transfer of substantially all of Source's assets. Furthermore, Source may unilaterally terminate the Merger Agreement in the event that the Average Closing Price of the shares of NDC Common Stock is less than the Lower Threshold Amount as of the Determination Date, subject to NDC's right to revise the Common Exchange Ratios based on the Lower Threshold Price. See "--Common Exchange Ratio Adjustment." CONDUCT OF BUSINESS PENDING THE MERGER Source has agreed pursuant to the Merger Agreement, unless the prior consent of NDC is obtained, and except as otherwise contemplated by the Merger Agreement, to operate its business only in the ordinary course, to preserve its business organizations and assets and to maintain its rights and franchises and to take no action that would materially adversely affect either the ability of either party to perform its covenants and agreements under the Merger Agreement or the ability of either party to obtain any consents or approvals pursuant to any contract, law, order or permit that are required for the transactions contemplated by the Merger Agreement. Source also agreed to (i) complete the Divestiture, (ii) amend the Designation to provide that the holders of Source Preferred Stock shall receive the Preferred Stock Consideration upon consummation of the Merger, (iii) terminate certain employment agreements and an executive pension plan, (iv) transfer, to the extent not already accomplished, all trademark registrations for the Source trademark into the name of Source, and (v) satisfy all indebtedness or other obligations between any of the subsidiaries involved in the Divestiture or PMSI or its subsidiaries on the one hand and Source or its subsidiaries on the other. In addition, the Merger Agreement contains certain other restrictions applicable to the conduct of the business of Source prior to consummation of the Merger, as described below. Source has agreed pursuant to the Merger Agreement not to take certain actions relating to the operation of its business pending consummation of the Merger without the prior approval of NDC. Those actions generally include, without limitation: (i) amending its Certificate of Incorporation or Bylaws; (ii) subject to certain exceptions, incurring any additional debt or other obligation for borrowed money on any asset of Source; (iii) acquiring or exchanging any shares of Source Capital Stock or paying any dividend or other distribution in respect of Source Capital Stock; (iv) subject to certain exceptions, issuing, selling or pledging additional shares of any Source Capital Stock, any rights to acquire any such stock or any security convertible into such stock, except pursuant to the exercise of outstanding stock options; (v) adjusting or reclassifying any of Source Capital Stock; (vi) subject to certain exceptions, purchasing any securities of or acquiring control over any other entity; (vii) granting any increase in compensation or benefits to its employees or officers (except as previously disclosed to NDC or as required by law), paying any bonus (except as previously disclosed to NDC or in accordance with any existing program or plan), entering into or amending any severance agreements with its officers or granting any increase in compensation or other benefits to any of its directors (except as previously disclosed to NDC); (viii) entering into or amending any employment contract that it does not have the unconditional right to terminate without certain liability, except as previously disclosed to NDC and except for any amendment required by law; (ix) adopting any new benefit plan or program or materially changing any existing plan or program; (x) making any significant changes in tax or accounting methods, except for any change required by law; (xi) commencing any litigation other than in accordance with past practice or settling any litigation for material money damages; or (xii) materially amending or terminating any material contracts including, without limitation, the Source Divestiture Agreement. In addition, Source has agreed not to solicit, directly or indirectly, any acquisition proposal from any other person or entity. Source also has agreed not to negotiate with respect to any such proposal, to provide information to any party making such a proposal or to enter into any agreement with respect to any such proposal, except in compliance with its legal obligations or the fiduciary obligations of its Board of Directors. Source has also agreed to cause its advisors and other representatives not to engage in any of the foregoing activities. 43 Pursuant to the Merger Agreement, NDC has agreed that, prior to the Effective Time, it will continue to conduct its business and the business of its subsidiaries in a manner designed in its reasonable judgment to enhance the long-term value of the NDC Common Stock and the business prospects of NDC. NDC further agrees that it will take no action which would materially adversely affect either the ability of either NDC or Source to obtain the consents required by the Merger Agreement or the ability of either NDC or Source to perform its covenants and agreements contained in the Merger Agreement. EXPENSES AND FEES The Merger Agreement provides that each party shall be responsible for its own costs and expenses incurred in connection with the negotiation and consummation of the transactions contemplated by the Merger Agreement, except that each of NDC and Source shall pay one-half of the filing fees payable in connection with the HSR filings, and NDC shall pay all costs associated with the Registration Statement and this Proxy Statement/Prospectus and printing costs incurred in connection with the Registration Statement and this Proxy Statement/Prospectus. If the Merger Agreement is terminated because (i) Source shall fail to call the Special Meeting, (ii) the stockholders of Source fail to approve the Merger, (iii) the Board of Directors of Source, to the exclusion of a competing proposal, shall fail to reaffirm its approval of the Merger or shall have affirmed, recommended or authorized a Competing Proposal, or (iv) Source has entered a binding agreement with respect to a Competing Proposal, then Source shall promptly pay all of the NDC Expenses. In addition to the foregoing, if the Merger Agreement is terminated because (i) Source fails to call the Special Meeting, or (ii) the stockholders of Source fail to approve the Merger Agreement, then Source shall pay to NDC the NDC Expenses plus $3,000,000. Further, if within twelve months following the termination of this Agreement: (i) by NDC because Source's Board of Directors shall have failed to reaffirm its approval of the Merger or shall have affirmed, recommended or authorized the entering into any other merger, share exchange, consolidation or transfer of substantially all of the assets of Source; or, (ii) by Source because it has entered into negotiations with a third party relating to the foregoing and pursuant to the continuing fiduciary duties of Source's Board of Directors as required by applicable law, Source has entered into a binding agreement with such third party; any third-party shall acquire, merge with, combine with, purchase substantially all of the assets of, or engage in any other business combination with, or purchase any equity securities involving an acquisition of 50% or more of the voting stock of Source, or enter into any binding agreement to do any of the foregoing, such third-party that is a party to the business combination shall pay to NDC, as a condition to consummation of such business combination, an amount in cash equal to $3,000,000. ACCOUNTING TREATMENT The Merger is anticipated to be accounted for under the "purchase" method of accounting, pursuant to which the assets and liabilities of Source will be recorded at their respective fair values and added to those of NDC as of the Effective Time. Financial Statements of NDC issued after the Effective Time will reflect such values and will not be restated retroactively to reflect the historical financial position or results of operations of Source. See "Summary." VOTING AGREEMENT NDC and the Preferred Stockholders have entered into the Voting Agreement which provides that the Preferred Stockholders will vote such Preferred Stockholder's shares of Source Preferred Stock in favor of the Merger, the execution and delivery by Source of the Merger Agreement and the approval of the terms thereof and each of the other transactions contemplated by the Merger Agreement, provided that the Merger Agreement has not been amended or waived so as to in any manner (i) affect the rights of the Preferred 44 Stockholders or their representatives or increase the Preferred Stockholders' obligations thereunder or (ii) increase the consideration payable to the holders of Source Common Stock, without the prior consent of the Preferred Stockholders. The Voting Agreement also provides that the Preferred Stockholders shall vote (or cause to be voted) such Preferred Stockholder's shares of Source Preferred Stock against (i) any merger agreement or merger (other than the Merger Agreement and the Merger), consolidation, combination, sale of substantial assets, reorganization, recapitalization, dissolution, liquidation or winding up of or by Source or (ii) any amendment of Source's Certificate of Incorporation or Bylaws or other proposal or transaction involving Source or any of its subsidiaries which amendment or other proposal or transaction would in any manner impede, frustrate, prevent or nullify the Merger, the Merger Agreement or any of the other transactions contemplated by the Merger Agreement. Each Preferred Stockholder has also agreed that such Stockholder shall not (i) transfer, or consent to any transfer of, any or all of the such stockholder's shares or any interest therein, except pursuant to the Merger; (ii) enter into any contract, option or other agreement or understanding with respect to any transfer of any or all of such shares or any interest therein, (iii) grant any proxy, power of attorney or other authorization in or with respect to such shares, except for the Voting Agreement, or (iv) deposit such shares into a voting trust or enter into a voting agreement or arrangement with respect to such shares, subject to certain limited exceptions. The Voting Agreement will terminate upon the earlier of the Effective Time, the date upon which the Merger Agreement is terminated in accordance with its terms, or December 15, 1997. APPRAISAL RIGHTS The holders of Source Capital Stock are entitled to appraisal rights under Section 262 of the Delaware General Corporation Law ("Section 262"). If the Merger is consummated, holders of Source Capital Stock who wish to exercise their appraisal rights will be entitled to have the "fair value" of their shares of Source Capital Stock at the Effective Time (exclusive of any element of value arising from the accomplishment or expectation of the Merger) judicially determined and paid to them in cash, together with interest, if any, by complying with the provisions of Section 262. Stockholders of record who desire to exercise their appraisal rights must satisfy all of the following conditions. A written demand for appraisal of their Source Capital Stock must be delivered to Source before the taking of the vote of the Source stockholders on adoption of the Merger Agreement. Such demand will be sufficient if it reasonably informs Source of the stockholder's identity and that the stockholder intends thereby to demand appraisal of his shares. This written demand for appraisal of shares must be in addition to and separate from voting against, abstaining from voting, or failing to vote on adoption of the Merger Agreement. Voting against, abstaining from voting, or failing to vote on adoption of the Merger Agreement will not constitute a demand for appraisal within the meaning of Section 262. Stockholders electing to exercise their appraisal rights under Section 262 must not vote for adoption of the Merger Agreement. Voting for adoption of the Merger Agreement, or delivering a proxy in connection with the Special Meeting (unless the proxy specifies a vote against, or abstaining from voting on, adoption of the Merger Agreement), will constitute a waiver of a stockholder's right of appraisal and will nullify any written demand for appraisal submitted by the stockholder. A demand for appraisal must be executed by or for the stockholder of record, fully and correctly, as such stockholder's name appears on such stockholder's Source Capital Stock certificates. If the Source Capital Stock is owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, such demand must be executed by the fiduciary. If the Source Capital Stock is owned of record by more than one person, as in a joint tenancy in common, such demand must be executed by all joint owners. An authorized agent, including an agent for two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the 45 agent must identify the record owner and expressly disclose the fact that, in exercising the demand, he is acting as agent for the record owner. A record owner, such as a broker, who holds Source Capital Stock as a nominee for others may exercise appraisal rights with respect to the shares held for all or less than all beneficial owners of shares as to which the holder is the record owner. In such case, the written demand must set forth the number of shares covered by such demand. Where the number of shares is not expressly stated, the demand will be presumed to cover all shares of Source Capital Stock outstanding in the name of such record owner. Stockholders who elect to exercise appraisal rights should mail or deliver their written demands to: Source Informatics, Inc., 45 Rockefeller Plaza, Suite 912, New York, New York 10111 Attention: Warren Hauser, General Counsel. The written demand for appraisal should specify the stockholder's name and mailing address, the number of shares of Source Common Stock and Source Preferred Stock owned, and state that the stockholder is thereby demanding appraisal. Within ten days after the Effective Time, Source must provide notice of the Effective Time to all stockholders who have complied with Section 262 and have not voted for adoption of the Merger Agreement. Within 120 days after the Effective Time, either Source or any stockholder who has complied with the required conditions of subsections (a) and (d) of Section 262 and who is otherwise entitled to appraisal rights may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of shares of the dissenting stockholders. If a petition for an appraisal is timely filed, after a hearing on such petition, the Court of Chancery will determine which stockholders are entitled to appraisal rights and will appraise the shares of Source Capital Stock owned by such stockholders, determining the fair value of such shares, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining fair value, the court is to take into account all relevant factors. In Weinberger v. UOP, Inc., et al, decided February 1, 1983, the Delaware Supreme Court expanded the considerations that could be considered in determining fair value in an appraisal proceeding, stating that "... proof of value by any techniques or methods, which are generally considered acceptable in the financial community and otherwise admissible in court ..." should be considered, and that ". . .[f]air price obviously requires consideration of all relevant factors involving the value of a company. . .". The Delaware Supreme Court stated that in making this determination of fair value the court must consider ". . .market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts which were known or which could be ascertained as of the date of merger and which throw any light on future prospects of the merged corporation. . .". The court further stated that ". . .elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and note the product of speculation, may be considered. . .". However, the court noted that Section 262 provides that fair value is to be determined ". . .exclusive of any element of value arising from the accomplishment or expectation of the merger. . .". At the hearing on such petition filed in the Court of Chancery, the court will determine the stockholders who have complied with Section 262 and who have become entitled to appraisal rights. The court may require dissenting stockholders to submit their stock certificates to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings. Failure of a dissenting stockholder to submit his certificates may result in the dismissal of such stockholder's appraisal proceedings. Stockholders considering seeking appraisal should have in mind that the fair value of their shares determined under Section 262 could be more than, the same as, or less than the consideration they are entitled to receive pursuant to the Merger Agreement if they do not seek appraisal of their shares and that investment banking opinions as to fairness from a financial point of view are not necessarily opinions as to fair value under Section 262. The cost of the appraisal proceeding may be determined by the Court of Chancery and taxed against the parties as the court deems equitable in the circumstances. Upon application of a dissenting stockholder, the court may order that all or a portion of the expenses incurred by any dissenting stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys' fees and the fees and expenses of 46 experts, be charged pro rata against the value of all shares of Source Capital Stock entitled to appraisal. In the absence of such a determination or assessment, each party bears its own expenses. Any stockholder who has duly demanded appraisal in compliance with Section 262 will not, after the Effective Time, be entitled to vote for any purpose the shares of Source Capital Stock subject to such demand or to receive payment of dividends or other distributions, if any, on such shares, except for dividends or distributions payable to stockholders of record as of a date prior to the Effective Time. At any time within 60 days after the Effective Time, any former holder of Source Common Stock will have the right to withdraw a demand for appraisal and to accept the consideration offered in the Merger Agreement; after this period, such holder may withdraw his demand for appraisal only with the consent of NDC. If no petition for appraisal is filed with the Court of Chancery within 120 days after the Effective Time, stockholders' rights to appraisal shall cease and all stockholders will be entitled to receive the consideration provided in the Merger Agreement. Inasmuch as NDC has no obligation to file such a petition, and has no present intention to do so, any stockholder who desires such a petition to be filed is advised to file it on a timely basis. However, no petition timely filed in the Court of Chancery demanding appraisal will be dismissed as to any stockholder without the approval of the court, and such approval may be conditioned upon such terms as the court deems just. Within 120 days after the Effective Time of the Merger, any stockholder who has complied with subsections (a) and (d) of Section 262 is entitled, upon written request, to receive from Source a statement setting forth the aggregate number of shares not voted in favor of the Merger and the aggregate number of holders of shares who have demanded appraisal. Such written statement shall be mailed to such stockholder within ten days after such request is received by Source or within ten days of the expiration of the period for delivery of demand for appraisal under Section 262, whichever is later. THE FOREGOING IS ONLY A SUMMARY OF THE RIGHTS OF A DISSENTING HOLDER OF SOURCE CAPITAL STOCK. ANY HOLDER OF SOURCE CAPITAL STOCK WHO INTENDS TO DISSENT SHOULD CAREFULLY REVIEW THE TEXT OF THE DELAWARE STATUTORY LAW SET FORTH IN ANNEX B TO THIS PROXY STATEMENT/PROSPECTUS AND SHOULD ALSO CONSULT WITH HIS ATTORNEY. THE FAILURE OF A SOURCE STOCKHOLDER TO FOLLOW PRECISELY THE PROCEDURES SUMMARIZED ABOVE AND SET FORTH IN ANNEX B TO THIS PROXY STATEMENT/PROSPECTUS, MAY RESULT IN LOSS OF APPRAISAL RIGHTS. NO FURTHER NOTICE OF THE EVENTS GIVING RISE TO APPRAISAL RIGHTS OR ANY STEPS ASSOCIATED THEREWITH WILL BE FURNISHED TO HOLDERS OF SOURCE CAPITAL STOCK, EXCEPT AS INDICATED ABOVE OR OTHERWISE REQUIRED BY LAW. In general, any dissenting stockholder who perfects his right to be paid the "fair value" of his Source Capital Stock in cash will recognize taxable gain or loss for federal income tax purposes upon receipt of such cash. See "Certain Federal Income Tax Consequences." RESALES OF NDC COMMON STOCK The shares of NDC Common Stock issued in connection with the Merger will be freely transferable under the Securities Act, except for shares issued to any stockholder who may be deemed to be an "affiliate" (generally including, without limitation, directors, certain executive officers, and beneficial owners of 10% or more of any class of capital stock) of Source for purposes of Rule 145 under the Securities Act as of the date of the Special Meeting. Such affiliates may not sell their shares of NDC Common Stock acquired in connection with the Merger except pursuant to an effective registration statement under the Securities Act or other applicable exemption from the registration requirements of the Securities Act. NDC may place restrictive legends on certificates representing NDC Common Stock issued to all persons who are deemed to be "affiliates" of Source under Rule 145. In addition, Source has agreed to use its reasonable efforts to cause each person or entity that is an "affiliate" to enter into a written agreement in substantially the form attached to the Merger Agreement relating to such restrictions on sale or other transfer. This Proxy Statement/Prospectus does not cover resales of NDC Common Stock received by any person who may be deemed to be an affiliate of Source. 47 SOURCE INFORMATICS INC. BUSINESS Source is a leading provider of proprietary health care information, technology and consulting services, primarily to the pharmaceutical and retail pharmacy markets. Source's services enable clients to better understand individual prescriber, payer, consumer, pharmaceutical manufacturer, pharmacy benefit manager and retail pharmacy behavior in order to compete more effectively in the market place. Source typically enters into significant, long-term relationships with its clients, providing integrated services to executives in the sales, marketing, market research and information technology areas of these organizations. Source provides a broad array of information, data mining and integrated marketing decision-making tools. The Source database is a repository of intelligence on managed care organizations, prescribers, retailers, prescriptions and non-personalized patient data. The principal database (the "Alpha Database") contains information on 1.6 billion prescriptions dispensed by retail and mail order pharmacies over the previous 12 months. Over 90% of the prescriptions in the Alpha Database are matched to over 1,000,000 prescribers, linking them at the individual script level. Source jointly exploits its databases in an operating venture with Pharmaceutical Marketing Services Inc. ("PMSI"). Simultaneously with the consummation of the Merger, NDC will acquire all of PMSI's interest in such operating venture ("Source US") through the acquisition of PMSI Database to which PMSI contributed all of its interest in Source US. See "--The Merger--General." Source provides critical competitive intelligence for client companies' sales representatives, linking the dispensed prescriptions back to the prescribers in their territory. Source also provides sales force managers with direct and comparative benchmarks to measure sales force performance and determine compensation at the individual territory level. Source's services enable client companies to target prescribers by their overall prescribing habits or by the mode of payment for prescriptions they write. Clients can identify the highest potential prescribers and their specific characteristics, and access market intelligence on the prescriber's practice. Other services match prescriptions to more than 850 health care payment plans, profiling the individual managed care plans and providing insight into their strategies. Source has recently launched new database services to enable pharmaceutical company clients to measure market share activity at the individual pharmacy level. Source operates in the rapidly changing health care market and has an active research and development effort. This development effort is driven by the changing needs of its client base, the rapid advances in information systems technology and evolving industry standards. Source's development efforts include significant revisions and additions to the architecture and functionality of Source's systems. Specifically, these efforts involve the transition from mainframe to client server technologies, the creation of a new prescription database which provides an enhanced level of detail, and the development of advanced analysis tools which allows for expanded data manipulation and multi-variable capabilities through the use of artificial intelligence. For the year ended June 30, 1997 Source generated total revenues of $59.9 million and net income of $6.5 million. Source has 400 employees. Source's principal executive offices are located at 2394 East Camelback Road, Phoenix, Arizona, 85016 and its telephone number is (602) 381-9500.

Revenue for the quarter ended September 30, 1997 was $15.3 million, an increase of $1.8 million or 13.5% over revenue for the quarter ended September 30, 1996. The increase was driven by new product sales, particularly in the area of services to help pharmaceutical companies measure market share activity at the individual retail pharmacy level. Production Costs. Production costs for the quarter ended September 30, 1997 were $3.7 million, (25% of revenue) compared to $3.6 million (27% of revenue) for the quarter ended September 30, 1996. The decrease as a percentage of revenue was due to productivity improvements from continued utilization of technology to reduce unit costs. Selling, General and Administrative Expenses. Selling, general and administrative expenses were $11.2 million (73% of revenue) for the quarter ended September 30, 1997, compared to $8.9 million (66% of revenue) for the quarter ended September 30, 1996. During the quarter, the company made significant investments in developing technology based services and new retail pharmacy programs that have been purchased by customers. The increase in selling, general and administrative expense as a percentage of revenue in the quarter ended September 30, 1997 versus the prior year was primarily due to the increased investment in these two areas to fulfill the requirements of new contracts. The company expects to begin recognizing the revenue from these contracts in the second quarter of this fiscal year. Depreciation and Amortization. Depreciation and amortization expenses for the quarter ended September 30, 1997, were $1.4 million, an increase of $0.4 million or 38% over depreciation and amortization expenses for the quarter ended September 30, 1996. The increase was primarily attributable to depreciation of capital investments for new computer systems, particularly the company's continuing transition from a mainframe platform to client server technology. Interest and Other Income/Interest Expense. For the quarter ended September 30, 1997, Sources net interest expense was $0.1 million compared to $0.1 million for the same period in 1996. OPERATING RESULTS FOR THE YEARS ENDED JUNE 30, 1997, 1996 AND 1995 Revenue. Revenue for the year ended June 30, 1997, was $59.9 million, an increase of $8.1 million or 15.6% over revenue for the year ended June 30, 1996. Revenue grew significantly in the information services and research and consulting divisions. The growth in the information services division revenue was driven by increased subscription sales for the Source Alpha database. The growth in the research and consulting division was driven by sales of newly launched consulting services. In both divisions growth was driven by increased business from existing clients and the addition of new clients. Revenue for the year ended June 30, 1996, was $51.8 million, an increase of $3.1 million or 6.4% over revenue for the year ended June 30, 1995. This growth was driven primarily by increases in subscription sales for the Source Alpha database, in the information services division. Production Costs. Production costs for the year ended June 30, 1997, were $14.8 million (25% of revenue) compared to $14.7 million (28% of revenue) for the year ended June 30, 1996. The decrease as a percentage of revenue was due to continued implementation of restructuring programs launched during the prior year. These programs included streamlining the production process and more effective utilization of technology in order to reduce unit costs. Production costs for the year ended June 30, 1996, were $14.7 million (28% of revenue) compared to $15.5 million (32% of revenue) for the year ended June 30, 1995. The decrease as a percentage of revenue was primarily attributable to the implementation of new restructuring programs designed to reduce unit costs. These programs included streamlining the production process and more effective utilization of technology in order to reduce unit costs and improve operating efficiency. Selling, General and Administrative Expenses. Selling, general and administrative expenses were $33.2 million (55% of revenue) for the year ended June 30, 1997, as compared to $29.7 million (57% of revenue) for the 1996 fiscal year. The increase was greater than prior years primarily due to one- time charges for consultants 49 retained to help Source transition from mainframe to client server technology and the expansion of work units to support retail chain and pharmacy market niche development. Selling, general and administrative expenses were $29.7 million (57% of revenue) for the year ended June 30, 1996, as compared to $27.7 million (57% of revenue) for the 1995 fiscal year. The increase was consistent with the growth of the business and the launch of a market niche penetration strategy, to expand beyond the Source's traditional market focus. The decrease in expense as a percentage of revenue was driven by the effective leveraging of Source's fixed expense base which kept operating costs flat, combined with minimal increases in employment costs. Depreciation and Amortization. Computer equipment and software are valued at their cost on the date of purchase and depreciated over periods of up to five years. The cost of updating and maintaining Source's databases is expensed as incurred, as is the cost of developing software for internal use. Depreciation and amortization expenses for the year ended June 30, 1997, were $5.2 million, an increase of $2.1 million or 67.7% over depreciation and amortization expenses for the year ended June 30, 1996. This increase represented significant investment supporting Source's transition from a mainframe to client server technology platform. Depreciation and amortization expenses for the year ended June 30, 1996, were $3.1 million, an increase of $1.2 million or 63.2% over depreciation and amortization expenses for the year ended June 30, 1995. The increased cost was primarily attributable to Source's investment in expanded computing capacity. Interest and Other Income/Interest Expense. Source invests its excess cash with major banks, and cash equivalents and marketable securities in a professionally managed fund. For the year ended June 30, 1997, Source's net interest expense was $0.1 million as compared to $0.4 million for the same period in 1996. The decrease was due to reduced borrowing levels given Source's increase in cash flow. For the year ended June 30, 1996, Source's net interest expense was $0.4 million as compared to $0.9 million for the 1995 fiscal year. The decrease was due to reduced borrowing levels, given Source's increase in cash flow. Income Tax Provision. There were no tax provisions for the years ended June 30, 1995, 1996 and 1997 respectively, due to net operating losses generated in prior years and applied during this period. In connection with the purchase of Source and PMSI Database, NDC has allocated $67 million of the purchase price to in-process research and development ("R&D") projects related to Source US. The results of operations of PMSI Database include its proportionate share of the Source US results of operations (approximately 24%), and, as a result, approximately $51 million of this charge has been attributed by NDC to Source and $16 million to PMSI Database. These allocations represent NDC's estimated fair value based on risk adjusted cash flows related to the incomplete projects. The discount rate NDC used was commensurate with the risk of the cash flows and takes into consideration the likelihood of completing the projects successfully. The development of these projects had not yet reached technological feasibility, and the technology has no alternative future use. Accordingly, these costs were expensed as of the acquisition date. The technology acquired in these acquisitions will require substantial additional development by NDC estimated to cost approximately $10 million over the next three years. Source's development efforts include significant revisions and additions to the architecture and functionality of Source's systems, Specifically, these efforts involve the transition from mainframe to client server technologies, the creation of a new prescription database which provides an enhanced level of detail, and the development of advanced analysis tools which allows for expanded data manipulation and multi-variable capabilities through the use of artificial intelligence. These efforts are important because the systems are used by Source to produce its main products and services. Finally, Source, in conjunction with NDC, is developing a major new software system aimed at providing more timely pharmaceutical product information to the health care industry. These projects are necessitated by competitive pressures and rapid advances in information system technology and, thus, are critical to the future success of Source. 50 SEASONALITY OF THE BUSINESS Historically, Source's financial results have varied from quarter to quarter, principally due to the timing of customer investments to new products and services and the timing of delivery of Source US services. For example, many of the pharmaceutical manufacturing customers of Source US report results on a calendar year basis. In general commitments are made by Source US's customers in the summer and fall for delivery in the first part of the next calendar year. Source US's fiscal year begins July 1. Source typically incurs expenses during the first half of its fiscal year (the last half of the calendar year) in preparation for roll-out of new products and services to meet customer requirements. Consequently, during Source US's first quarter, significant expense with respect to new products is incurred to generate revenues which should be recognized in future quarters. LIQUIDITY AND CAPITAL RESOURCES At September 30, 1997, Source's cash and cash equivalents totaled $4.3 million. Excluding a parent company obligation which will be forgiven at the Effective Time, Source's current ratio was 0.53:1 at September 30, 1997. In comparison to the quarter ended September 30, 1996, cash and cash equivalents increased due to the growth in the company's business and resulting increase in cash flow. At June 30, 1997, Source's cash and cash equivalents and marketable securities totaled $2.8 million. Excluding a parent company obligation which will be forgiven at the Effective Time, Source's current ratio was 0.63:1. During the year ended June 30, 1997, cash and cash equivalents and short-term marketable securities decreased due to the timing in accounts receivable collection and investments in Source Europe. Source anticipates that existing cash, together with internally generated funds, will provide Source with the resources necessary to meet Source's working capital requirements in fiscal 1998 and subsequent years. 51 SECURITIES OWNERSHIP The following table sets forth certain information as of September 30, 1997, regarding the ownership of Source Common Stock and Preferred Stock by (i) certain stockholders or groups of related stockholders who, individually or as a group, are the beneficial owners of 5% or more of any class of the Source Capital Stock and (ii) the executive officers and directors of Source.

The following is a summary of the material differences in the rights of stockholders of NDC and Source. Both NDC and Source are Delaware corporations governed by the DGCL. Accordingly, except as set forth below, there are no material differences between the rights of an NDC stockholder under NDC's Certificate of Incorporation and Bylaws and the DGCL, on the one hand, and the rights of a Source stockholder under Source's Certificate of Incorporation and Bylaws and the DGCL, on the other hand. This summary does not purport to be a complete discussion of, and is qualified in its entirety by reference to, the DGCL and the Certificate of Incorporation and Bylaws of each corporation. AUTHORIZED CAPITAL STOCK NDC The authorized capital stock of NDC consists of 100,000,000 shares of Common Stock, par value $.125 per share, and 1,000,000 shares of Preferred Stock, par value $1.00 per share. The following description of the capital stock is qualified in all respects by reference to the Certificate of Incorporation, as amended, and Bylaws, as amended, of NDC, copies of which are on file at NDC's principal executive offices. NDC Common Stock. The holders of NDC Common Stock, subject to such rights as may be granted to the holders of NDC Preferred Stock, elect all directors and are entitled to one vote per share. All shares of NDC Common Stock participate equally in dividends when, as and if declared by the Board of Directors and share ratably, subject to the rights and preferences of any NDC Preferred Stock, in net assets on liquidation. The shares of NDC Common Stock outstanding are duly authorized, validly issued, fully paid and nonassessable. The shares of NDC Common Stock have no preference, conversion, exchange, preemptive or cumulative voting rights. Stock Purchase Rights. Pursuant to a Rights Agreement dated as of January 18, 1991, each share of NDC Common Stock is issued one NDC right (an "NDC Right") which entitles the registered holder to purchase from the NDC one one- hundredth of a share (a "Unit") of Series A Junior Participating Preferred Stock, par value $1.00 per share (the "NDC Participating Preferred"), at a purchase price of $45.00 per Unit, subject to adjustment. Until the Separation Date (as hereinafter defined, see "--Stockholder Rights Plan"), the NDC Rights are unexercisable and attach to and transfer with the NDC Common Stock certificates. The NDC Rights may have certain anti-takeover effects because the rights will cause substantial dilution to a person or group that attempts to acquire NDC on terms not approved by the Board of Directors of NDC unless the offer is conditioned on a substantial number of NDC Rights being acquired. However, the NDC Rights should not interfere with the Merger or any other business combination approved by a majority of the directors since the NDC Rights may be redeemed by NDC at $.01 per NDC Right at any time on or prior to a stock acquisition. Thus, the NDC Rights are intended to encourage persons who may seek to acquire control of NDC to initiate such an acquisition through negotiations with the Board of Directors. However, the effect of the NDC Rights may be to discourage a third party from making a partial tender offer or otherwise attempting to obtain a substantial equity position in the equity securities of, or seeking to obtain control of, NDC. To the extent any potential acquirers are deterred by the NDC Rights, the NDC Rights may have the effect of preserving incumbent management in office. NDC Preferred Stock. NDC is authorized to issue 1,000,000 shares of Preferred Stock, par value $1.00 per share, none of which is outstanding, although 300,000 shares of Preferred Stock have been reserved for issuance pursuant to the NDC Rights described above. NDC Preferred Stock may be issued from time to time by the Board of Directors of NDC, without stockholder approval, in such series and with such voting powers, full or limited, and such designations, preferences and relative, participating, optional or other special rights, qualifications, limitations or restrictions as may be fixed by the Board of Directors. The issuance of NDC Preferred Stock by the Board of Directors could adversely affect the rights of holders of shares of NDC Common 53 Stock since NDC Preferred Stock may be issued having preference over the NDC Common Stock with respect to dividends and in liquidation, and have voting rights, contingent or otherwise, that could dilute the voting rights, net income per share and net book value of the NDC Common Stock. In addition, while the Board of Directors has no current intention of doing so, the ability of the Board of Directors to issue shares of NDC Preferred Stock and to set the voting powers and such designations, preferences and relative, participating, optional or other special rights, qualifications, limitations or restrictions thereof without further stockholder action could help to perpetuate incumbent management of NDC or prevent a business combination involving NDC that is favored by NDC's stockholders. As of the date of this Proxy Statement/Prospectus, other than in connection with the NDC Rights described above, the Board of Directors has not authorized the issuance of any shares of NDC Preferred Stock, and NDC has no agreements, arrangements or understandings with respect to the issuance of any shares of NDC Preferred Stock. Source The authorized capital stock of Source consists of 12,000,000 shares of Source Common Stock, $.01 par value, and 2,000,000 shares of Source Preferred Stock, $1.00 par value. The following description of Source Capital Stock is qualified in all respects by reference to the Certificate of Incorporation, as amended, and Bylaws, as amended, of Source, copies of which are on file at Source's principal executive offices. Source Common Stock. The holders of Source Common Stock are entitled to one vote per share on all matters submitted to the stockholders for a vote. Subject to the preferences of the Source Preferred Stock, all shares of Source Common Stock participate equally in dividends when, as and if declared by the Board of Directors and share ratably subject to the rights and preferences of any Source Preferred Stock, in net assets on dissolution. The shares of Source Common Stock outstanding are duly authorized, validly issued, fully paid and nonassessable. The shares of Source Common Stock have no preference, conversion, exchange or cumulative voting rights. Source Preferred Stock. The Board of Directors, pursuant to Source's Certificate of Incorporation, has designated one series, consisting of 1,041,667 shares, of Source Preferred Stock (the "Source Preferred Stock"), all of which shares are outstanding. The Source Preferred Stock was issued in connection with the spin-off of Source from Walsh International Inc. ("Walsh") immediately prior to Walsh's initial public offering of securities in April 1996. The terms of the Source Preferred Stock are based upon and substantially reflect the terms of a series of preferred stock of Walsh that was issued to private investors in 1993. The terms of the Source Preferred Stock were negotiated with such investors in order to induce them to convert their Walsh preferred shares into Walsh common stock at the time of the public offering, and are intended to substantially preserve the originally negotiated rights of the Walsh preferred stock, including redemption rights and liquidation preference. Because several of such investors were subject to underwriters' "lock-up" agreements and could not liquidate their Walsh common stock immediately following the public offering, the Source Preferred Stock also includes provisions that, in effect, give limited price protection with respect to the Walsh common stock. See "-- Redemption." The number of shares designated as Source Preferred Stock may be increased or decreased (but not below the number then outstanding) by resolution of the Board of Directors. The rights of the holders of Source Preferred Stock are prior to those of the holders of Source Common Stock with respect to dividends and amounts distributable to stockholders upon liquidation. Redemption. The Source Preferred Stock is subject to mandatory redemption and, in certain circumstances, optional redemption at the election of the holder. In general, the redemption price of the Source Preferred Stock per share is the sum of (i) $11.33, plus (ii) any declared and undistributed dividends in respect of the Source Preferred Stock, plus (iii) on the date on which all outstanding shares of Source Preferred Stock are redeemed, the "Additional Redemption Amount." The Additional Redemption Amount is calculated, in the case of each holder of Source Preferred Stock, as (a) 74% of the initial public offering price of the Walsh common stock (i.e., $8.88) multiplied by the number of shares of Walsh common stock held by such holder on the date of consummation of the Walsh initial public offering, less (b) the net proceeds received by such holder from any sales of its shares of Walsh common stock, less (c) the aggregate value of any securities received by it in respect of its shares of Walsh common stock pursuant to a merger or other business combination involving 54 Walsh, less (d) the aggregate value of Walsh common stock otherwise transferred by it to unaffiliated third parties, less (e) 50% of the aggregate value of the shares of Walsh common stock held by it on the date of final redemption over the amount provided in clause (e). In effect, the Additional Redemption Amount is designed to compensate the holders of Source Preferred Stock to the extent that the value of (or proceeds received from disposition of) their Walsh common stock is less than $8.88 per share (74% of the initial public offering price of $12 per share). This level of price protection with respect to the Walsh common stock was a negotiated compromise between Source and Walsh, on the one hand, and the holders of the Walsh preferred stock, on the other hand. The market value of the Walsh common stock (calculated in accordance with the Source Certificate of Incorporation as the average closing price of the Walsh common stock for the ten trading days commencing twelve trading days before September 30) was $11.18. Pursuant to the formula determining the Additional Redemption Amount, 50% of this value ($5.59) would be deducted from the maximum $8.88 Additional Redemption Amount. As a result, in general, the Additional Redemption Amount will be zero unless, as of the date of determination, the market value of the Walsh common stock is less than $3.29. The closing price of the Walsh common stock on the Nasdaq National Market was $10.25 on November 6, 1997. Pursuant to the existing terms of the Source Certificate of Incorporation, the shares of Source Preferred Stock would be mandatorily redeemable as follows: 520,834 shares on September 30, 1997, and the remaining outstanding shares on June 30, 1998. In August 1997, the holders of the Source Preferred Stock consented to the deferral of the September 30, 1997 redemption until December 15, 1997. If the Merger is not consummated on or before such date, then the 520,834 shares of Source Preferred Stock originally scheduled for redemption on September 30, 1997 will be manditoraly redeemable. Upon the occurrence of a change of control event, each holder of Source Preferred Stock has the right to require Source to redeem such holder's Shares. The Merger constitutes such a change of control event. The merger consideration payable to the holders of the Source Preferred Stock equals the amount that such holders would be entitled to receive upon redemption as of the date of consummation of the Merger. See "Merger." DIVIDENDS. Holders of Source Preferred Stock are entitled to share ratably in all dividends declared and paid to the holders of Source Common Stock. Furthermore, no dividend may be declared, set aside, or paid to the holders of Source Common Stock or any other class or series of Source Capital Stock ranking junior to the Source Preferred Stock unless the full cumulative dividends (including the dividend, distribution, redemption, purchase or other acquisition) on all outstanding shares of Source Preferred Stock shall have been, or shall then be, paid. CONVERSION. The shares of Source Preferred Stock are convertible, at the option of the holder thereof, into an equal number of shares of Source Common Stock (the "Conversion Ratio"). The Conversion Ratio is automatically proportionately adjusted in the event of a stock split, stock dividend, issuance of warrants, issuance of convertible debt or securities, or reclassification with respect to shares of Source Common Stock. MERGER. In general, in case of any consolidation or share exchange of Source with, or merger of Source into, any other person, any merger of another person into Source (including the Merger, but excluding any other merger which does not result in any reclassification, conversion, exchange, or cancellation of outstanding shares of Source Common Stock) or any sale or transfer of all or substantially all of the assets of Source, the holders of shares of Source Preferred Stock are entitled to receive the same consideration as if such holder would have received had he converted his Source Preferred Stock into Source Common Stock immediately prior to such consolidation, merger, share exchange, sale or transfer. However, in the event of a merger (such as the Merger) that constitutes a "Change of Control Event" under the Designation, holders of the Source Preferred Stock have the right to elect to have their shares redeemed at a redemption price equal to the greater of (a) $11.33 and (b) the greater of the market price of the Source Common Stock and the price per share of Source Common Stock in the Change of Control transaction, plus, in the case of both (a) and (b), the Additional Redemption Amount and any declared but unpaid dividends or other distributions with respect to the Source Preferred Stock. The Merger Agreement accordingly provides that the holders of the Source Preferred Stock are entitled to receive merger 55 consideration of $11.33 per share, subject to adjustment to equal the amount that the holders would receive if their shares had been redeemed (i.e., an increase to the extent of any applicable Additional Redemption Amount and any declared but unpaid distributions). VOTING. Except as hereinafter described and as is required by law, holders of the Source Preferred Stock have the right and power to vote on any matter upon which, or in any proceeding at which, the holders of Source Common Stock are entitled to vote and to be represented at and to receive notice of any meeting of stockholders. Each holder of Preferred Stock shall be entitled to that number of votes for each share of Common Stock obtainable upon conversion of such Stock on the record date for the vote which is being taken, or if no such record date is established at the date such vote is taken of any written consent of the stockholders is solicited. The holders of shares of Preferred Stock and shares of Common Stock shall vote together and not as separate classes except as otherwise provided herein or by law. The holders of Series A Preferred Stock will vote as a separate class and approval of 51% of the holders will be required to create any additional class of preferred stock, create any class of common stock other than the class presently authorized for issuance, amend the Certificate of Incorporation or By-laws of the corporation or increase the number of shares of Series A Preferred Stock authorized for issuance. In addition, pursuant to the Stockholders Agreement, the consent of the holders of at least a majority of the outstanding Preferred Stock is required to approve the Merger. DIRECTORS AND CLASSES OF DIRECTORS NDC The Board of Directors of NDC is divided into three classes as nearly equal in number as the total number of directors permits. Directors are elected to each class at successive annual meetings to serve three-year terms. Any newly created or eliminated directorships resulting from an increase or decrease in the number of authorized directors are divided equally among the three classes so as to maintain such classes as nearly equal as possible. Any director or the entire Board of Directors of NDC may be removed from office only upon the affirmative vote of at least 80% of the holders of all classes of NDC stock, voting as a single class. The above-mentioned provisions (the "NDC Board Provisions") with regard to the Board of Directors of NDC may have certain anti-takeover effects by preventing or delaying a change in the membership of the Board of Directors of NDC. The NDC Board Provisions are intended to encourage persons who may seek to acquire control of NDC to initiate such an acquisition through negotiations with the Board of Directors of NDC. However, the effect of the NDC Board Provisions may be to discourage a third party from making a partial tender offer or otherwise attempting to obtain a substantial position in the equity securities of, or seeking to obtain control of, NDC. To the extent any potential acquirers are deterred by the NDC Board Provisions, the NDC Board Provisions may have the effect of preserving incumbent management in office. Source The Board of Directors of Source consists of 8 members, serving as a single class. Directors of Source serve until their successors are elected and qualified. Directors of Source may be removed, with or without cause, by the affirmative vote of the holders of a majority of the shares of Source Capital Stock entitled to vote at an election of directors. STOCKHOLDER MEETINGS NDC NDC's Bylaws provide for annual meetings of stockholders to be held on the fourth Thursday of October and for special meetings to be held on call of the Chairman or President or at the request of a majority of the members of the Board of Directors. The NDC Bylaws do not permit stockholders to call a special meeting of stockholders. Stockholders entitled to vote are entitled to written notice stating the place, date, hour and, in the case of a special meeting, the purpose of the meeting, not less than 10 nor more than 50 days before the date of the meeting. The holders of a majority of the stock issued and outstanding and entitled to vote at a meeting, present in person or represented by proxy, constitutes a quorum. When a quorum is present at 56 a meeting, the vote of the holders of a majority of the stock having voting power, present in person or by proxy, can approve any resolution properly brought before the meeting, except for resolutions: (i) increasing the number of authorized shares of capital stock; (ii) approving a Business Combination (as defined in NDC's Certificate of Incorporation; (iii) amending Article Fourth of NDC's Certificate of Incorporation (Business Combination provisions); (iv) removing any director or the entire Board of Directors; (v) amending Article Eighth, Thirteenth, or Fourteenth of NDC's Certificate of Incorporation (board classes, no stockholder action except at a meeting, and board authority to alter, amend or repeal bylaws without stockholder approval); or (vi) requiring a greater vote than is provided by applicable law. The foregoing resolutions must be approved by the affirmative vote of (i) 50%; (ii) 66.67%; (iii) 66.67%; (iv) 80%; and (v) 80%, respectively of the stockholders entitled to vote. Source Source's bylaws provide for annual meetings to be held on such dates and at such times as shall be designated by the Board of Directors and for special meetings to be held (i) at the request of the Chairman or a majority of the Board of Directors; or (ii) at the request of the President or the Secretary of Source. Stockholders entitled to vote are entitled to written notice stating the place, date, hour, and, in the case of a special meeting, the purpose of the meeting, not less than 10 nor more than 60 days before the date of the meeting. The holders of a majority of the stock issued and outstanding and entitled to vote at a meeting, present in person or represented by proxy, constitute a quorum. When a quorum is present at a meeting, the vote of the holders of a majority of the stock having voting power, present in person or by proxy, can approve any resolution properly brought before the meeting, except where a greater vote is required by applicable law. ANTI-TAKEOVER PROVISIONS NDC The provisions of NDC's Certificate, Bylaws, and the NDC Rights Agreement contain certain protective provisions, which are intended to facilitate stability of leadership and enhance the NDC Board of Directors' role in connection with attempts to acquire control of NDC so that the Board may further and protect the interests of NDC, its stockholders and its other constituencies as appropriate under the circumstances. In particular, if the Board determines that a sale of control is in the best interests of the stockholders, these protective provisions are designed to enhance the Board's ability to maximize the value to be received by the stockholders upon such a sale. Although NDC management believes that the protective provisions are beneficial to NDC's stockholders, such provisions may also discourage certain acquisition proposals, which may deprive NDC's stockholders of certain opportunities to sell their shares at a premium over prevailing market prices. Pursuant to its authority to issue different series of NDC Preferred Stock, the Board of Directors of NDC has established the NDC Rights Agreement and has designated the preferences and rights of the NDC Participating Preferred to include certain provisions which may have the effect of discouraging unsolicited offers to acquire NDC. See "--Stockholder Rights Plan." Source The provision of Source's Certificate of Incorporation granting the Source Board of Directors the authority to provide for the issuance of Source Preferred Stock in series may discourage certain acquisition proposals, which may deprive Source's stockholders of certain opportunities to sell their shares at a premium over prevailing market prices. See "--Source Preferred Stock." STOCKHOLDER RIGHTS PLAN NDC Each share of NDC Common Stock has attached to it an NDC Right issued pursuant to a Rights Agreement between NDC and Wachovia Bank of North Carolina, N.A., as Rights Agent (the "NDC Rights Agreement"). Each NDC Right entitles its registered holder to purchase one one-hundredth of a share of NDC Participating Preferred at a price of $45.00 (the "Rights Purchase Price"), as adjusted from time to time under certain circumstances, after the earlier of (i) the tenth day following the commencement of, or first public announcement 57 of an intention to commence, a tender offer or exchange offer which, if successful, would result in any person or group having beneficial ownership of 15% or more of the outstanding NDC Common Stock (an "Acquiring Person"), and (ii) the tenth day after the first date of a public announcement that a person or group has acquired, or obtained the right to acquire, beneficial ownership of 15% or more of the outstanding NDC Common Stock (the "Stock Acquisition Date") (in either case, the "Separation Date"). The NDC Rights will not trade separately from the NDC Common Stock unless and until the Separation Date occurs. The dividend, liquidation and voting rights of the shares of NDC Participating Preferred, are designed so that the value of the one one-hundredth of a share of NDC Participating Preferred purchasable upon the exercise of each NDC Right should approximate the value of one share of NDC Common Stock. In the event that any person or group becomes an Acquiring Person, each holder of an NDC Right, except an Acquiring Person or any affiliate or associate thereof, will be entitled to purchase at the then-current Rights Purchase Price shares of NDC Common Stock with a market value of two times the Rights Purchase Price. In the event that NDC is acquired in a merger or other business combination, or 30% or more of its assets or earning power is sold to any person or group other than NDC or its wholly-owned subsidiaries, then, in each such case, each holder of an NDC Right, except an Acquiring Person or an affiliate or an associate thereof, will be entitled to purchase shares of stock of the other party to the business combination with a market value of two times the Rights Purchase Price. Prior to the Stock Acquisition Date the NDC Rights are redeemable for one cent per NDC Right at the option of the Board of Directors. The NDC Rights will expire on January 18, 2001 or at an earlier date under certain circumstances. The NDC Rights will not prevent a takeover of NDC. The NDC Rights, however, may cause substantial dilution to a person or group that acquires 20% or more of the NDC Common Stock unless the NDC Rights are first redeemed or terminated by the Board of Directors of NDC. Nevertheless, the NDC Rights should not interfere with a transaction that is, in the opinion of NDC's Board of Directors, in the best interests of NDC and its stockholders because the NDC Rights can be redeemed or terminated, as hereinbefore described, before the consummation of such a transaction. Source Source has not adopted any rights or similar plan. EXPERTS The consolidated financial statements of NDC at May 31, 1996 and 1997, and for each of the years in the three-year period ended May 31, 1997, incorporated by reference from NDC's Annual Report on Form 10-K for the fiscal year ended May 31, 1997, have been audited by Arthur Andersen LLP, independent auditors, as set forth in their report thereon included therein and incorporated herein by reference in reliance upon such reports given on the authority of said firm as experts in accounting and auditing.

LEGAL MATTERS The legality of the shares of NDC Common Stock being offered hereby is being passed upon for NDC by Alston & Bird LLP, Atlanta, Georgia. Neil Williams, a partner of Alston & Bird LLP, is a director and stockholder of NDC. 58 ANNEX A AGREEMENT AND PLAN OF MERGER A-1 AGREEMENT AND PLAN OF MERGER BY AND AMONG NATIONAL DATA CORPORATION, DUNKIRK, INC., AND SOURCE INFORMATICS INC.

In addition, upon such adoption and upon execution and delivery of the Escrow Agreement by the Stockholder Representative, the Escrow Agreement shall constitute the legal, valid and binding obligations of each Stockholder. (b) The adoption of this Agreement by the holders of Source Preferred Stock shall constitute ratification of this Agreement. Upon such adoption, this Agreement shall constitute the legal, valid and binding obligation of each holder of Source Preferred Stock. ARTICLE 3 Manner of Converting Shares 3.1 Conversion of Shares. Subject to the provisions of this Article 3, at the Effective Time, by virtue of the Merger and without any action on the part of NDC, Source, Sub or the stockholders of any of the foregoing: (a) Each share of capital stock of NDC issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding from and after the Effective Time. (b) Each share of Sub Common Stock issued and outstanding immediately prior to the Effective Time shall cease to be outstanding and shall be converted into one share of Source Common Stock. (c) Each share of Source Common Stock (excluding shares held by any Source Entity or any NDC Entity, and excluding shares held by stockholders who perfect their statutory dissenters' rights as provided in Section 3.7) issued and outstanding immediately prior to the Effective Time shall cease to be outstanding and shall be converted into and exchanged for the right to receive (i) the Common Cash Amount, if any, and that fraction of a share of NDC Common Stock equal to 1,099,716 shares (the "Payment Shares") A-4 divided by the total number of shares of Source Common Stock outstanding at the Closing Date (the "Common Base Exchange Ratio"); provided, however, that the Payment Shares shall be first reduced by the Option Shares (as defined in Section 3.1(c)(4) below), and (ii) that fraction of a share of NDC Common Stock equal to 455,840 shares (the "Stock Escrow") divided by the total number of shares of Source Common Stock outstanding at the Closing Date, subject to the provisions of Section 3.2, Article 10 and the Escrow Agreement (the "Common Escrow Exchange Ratio"); (1) At the Closing Date, the "Common Cash Amount" shall be calculated by dividing $31,750,000, the aggregate cash consideration payable by NDC hereunder (the "Aggregate Cash Amount"), less the Preferred Stock Merger Consideration (as defined in Section 3.1(d)) and the Transaction Expenses (as defined in Section 3.1(c)(2) below), by the total number of shares of Source Common Stock outstanding at the Closing Date. (2) At the Closing Date, Source shall prepare and deliver to NDC a schedule substantially in the form of Schedule 1 attached hereto (the "Expense Schedule"), indicating the expenses incurred but unpaid as of the Closing Date which are of the type disclosed on Schedule 1 and which are directly associated with the transaction contemplated by this Agreement, including, without limitation, all expenses incurred in connection with Source's termination of certain employment agreements and an executive pension plan pursuant to Section 7.1(d) hereof (the "Transaction Expenses"); provided, however, if the sum of the Preferred Stock Merger Consideration and the Transaction Expenses exceed the Aggregate Cash Amount ("Excess Expense"), then the Payment Shares shall be reduced by that number of shares of NDC Common Stock equal to the quotient of (i) the Excess Expense divided by (ii) the Average Closing Price as of the Closing Date. (3) If, at the close of trading on the tenth trading day immediately preceding the Closing Date (the "Determination Date"), the Average Closing Price shall be greater than $50.50 (the "Upper Threshold Price"), the "Common Exchange Ratios" (defined to include the Common Base Exchange Ratio and the Common Escrow Exchange Ratio) shall each be adjusted to equal that fraction of a share of NDC Common Stock (rounded to the nearest ten thousandth of a share) obtained by dividing the product of the Common Base Exchange Ratio or the Common Escrow Exchange Ratio, as the case may be, and the Upper Threshold Price by the Average Closing Price at the Determination Date; provided further, that, in the event that the Average Closing Price on the Determination Date shall be less than $37.25 (the "Lower Threshold Price" and, together with the Upper Threshold Price, the "Threshold Prices"), the Common Exchange Ratios may, at the sole discretion of NDC, and in accordance with the provisions of Section 11.1(h), each be adjusted to equal that fraction of a share of NDC Common Stock (rounded to the nearest ten thousandth of a share) obtained by dividing the product of the Common Base Exchange Ratio or the Common Escrow Exchange Ratio, as the case may be, and the Lower Threshold Price by the Average Closing Price at the Determination Date. (4) At the Closing Date, Source shall have secured the cancellation of all outstanding options and warrants to purchase shares of Source Common Stock and shall provide to NDC a schedule of the number of shares of NDC Common Stock (the "Option Shares") payable to the holders of such options and warrants in consideration of such cancellation. (5) Pursuant to the NDC Rights Agreement, each share of NDC Common Stock issued in connection with the Merger upon conversion of Source Common Stock shall be accompanied by a NDC Right. (d) Each share of Source Preferred Stock (excluding shares held by any Source Entity or any NDC Entity, and excluding shares held by stockholders who perfect their statutory dissenters' rights as provided in Section 3.7) issued and outstanding immediately prior to the Effective Time shall cease to be outstanding and shall be converted and exchanged for the right to receive an amount equal to $11.33, subject to adjustment to equal that amount such holder's shares of Source Preferred Stock would otherwise receive if such holder were redeemed on the Closing Date pursuant to the Designation (such aggregate amount, as adjusted, the "Preferred Stock Merger Consideration"). A-5 3.2 Preliminary Balance Sheet. (a) Source will cause to be prepared and delivered to NDC a balance sheet for Source, pro forma giving effect to the Divestiture, as of the most recent month ending more than ten days prior to the Closing Date (the "Preliminary Balance Sheet") and a certificate based on such Preliminary Balance Sheet setting forth Source's calculation of Working Capital, Current Assets and Current Liabilities as of such date ("Estimated Working Capital," "Estimated Current Assets" and "Estimated Current Liabilities," respectively). The Preliminary Balance Sheet shall (w) include the consolidated financial position of Source and the Source Subsidiaries, (x) fairly present the financial position of Source and the Source Subsidiaries as at the close of business on such date in accordance with generally accepted accounting principles applied on a basis consistent with those used in the preparation of the balance sheet dated March 31, 1997 (the "Source Balance Sheet") previously delivered to NDC, (y) include no material increase in long-term indebtedness, and include line items substantially consistent with those in the Source Balance Sheet, and (z) be prepared in accordance with accounting policies and practices consistent with those used in the preparation of the Source Balance Sheet. As used in this Agreement, "Working Capital" shall mean the amount equal to Current Assets less Current Liabilities; "Current Assets" shall mean the amount equal to the sum of cash, accounts receivable (net of any reserves), inventories, prepaid expenses, work-in-process, and any other current assets recognized by GAAP; and "Current Liabilities" shall mean the amount equal to the sum of accounts payable, accrued current liabilities of Source (other than the current portion of capitalized lease obligations), accrued sales commissions (but only as to revenues realized and included in the Source and Source Subsidiaries' statements of income prior to such date), Accrued Bonuses, accrued vacation pay, current portion of long-term indebtedness, pre-billed revenues and any other current liabilities recognized by GAAP, but excluding all Transaction Expenses. (b) NDC shall have five (5) business days from the receipt of the Preliminary Balance Sheet and the calculation of Estimated Working Capital, Estimated Current Assets and Estimated Current Liabilities delivered pursuant to Section 3.2(a) to review such statement and calculations and following such review such shall be final and binding upon the parties hereto. (c) If Estimated Current Assets are less than the product of 0.9416 times Estimated Current Liabilities (such amount, the "Estimated Working Capital Adjustment") as of the date of the Preliminary Balance Sheet, the Escrow Shares payable by NDC pursuant to Section 3.1(c) shall be decreased by the number of shares of NDC Common Stock equal to the Estimated Working Capital Adjustment divided by the Average Closing Price as of the Closing Date; provided, however, in the event this reduction of the Escrow Shares exceeds 113,960 shares, the Payment Shares shall then be decreased similarly in an amount equal to such excess. 3.3 Closing Balance Sheet. (a) As promptly as practicable, but not later than 30 days after the Closing Date, NDC will cause to be prepared and delivered to the Stockholder Representative a balance sheet, giving effect to the Divestiture, for Source as of the Closing Date (the "Closing Balance Sheet") setting forth NDC's calculation of Working Capital, Current Assets and Current Liabilities as of the Closing Date ("Closing Working Capital", "Closing Current Assets" and "Closing Current Liabilities," respectively). The Closing Balance Sheet shall (w) include the consolidated financial position of Source and the Source Subsidiaries (x) fairly present the consolidated financial position of Source and the Source Subsidiaries as at the close of business on the Closing Date in accordance with generally accepted accounting principles applied on a basis consistent with those used in the preparation of the Source Balance Sheet, (y) include no material increase in long-term indebtedness, and include line items substantially consistent with those in the Source Balance Sheet, and (z) be prepared in accordance with accounting policies and practices consistent with those used in the preparation of the Source Balance Sheet. (b) The Closing Balance Sheet and the calculation of Closing Working Capital, Closing Current Assets and Closing Current Liabilities delivered pursuant to Section 3.3(a) shall be deemed final upon the earliest of (i) the date on which NDC and the Stockholder Representative jointly agree that such documents are final, (ii) the 30th day after delivery of such documents pursuant to Section 3.3(a), if the Stockholder Representative has not A-6 delivered a notice to expressing disagreement with such calculations and setting forth its calculation of such amount(s), and (iii) the date on which all disputes relating to such statements and calculations between the parties are resolved in accordance with Section 3.3(c). If the Stockholder Representative delivers a notice of disagreement pursuant to this Section 3.3(b) it shall specify those items or amounts as to which it disagrees, and it shall be deemed to have agreed with all other items and amounts contained in the Closing Balance Sheet and the calculation of Closing Working Capital delivered pursuant to Section 3.3(a) (except to the extent resolution of the items or amounts to which it expresses disagreement requires conforming changes to other items and amounts contained in the Closing Balance Sheet or the calculation of Closing Working Capital). (c) If the Stockholder Representative shall deliver a notice of disagreement pursuant to Section 3.3(b), the Stockholder Representative and NDC shall, during the 30 days following such delivery, use their reasonable efforts to reach agreement on the disputed items or amounts (the "Disputed Amounts"). If, during such period, the Stockholder Representative and NDC are unable to reach such agreement, they shall promptly thereafter cause Price Waterhouse LLP (or if said firm shall be unwilling to act thereunder, such other independent accountants of nationally recognized standing reasonably satisfactory to NDC and the Stockholder Representative), promptly to review this Agreement, the documents delivered pursuant to Section 3.3(a) and any other documents necessary to calculate the Disputed Amounts (including all work papers of the parties used in calculating the Disputed Amounts). In making such calculation, such independent accountants shall act as experts and not arbitrators and shall consider only the Disputed Amounts, solely in accordance with the terms of this Agreement. Such independent accountants shall deliver to the Stockholder Representative and NDC, as promptly as practicable, a report setting forth such calculation. Such report shall be final and binding upon the Stockholders and NDC. The cost of such review and report shall be borne by (i) the Stockholders if the difference between Final Working Capital (defined in Section 3.4 below) shown in the independent accountant's calculation and the Stockholder Representative's calculation of Closing Working Capital delivered pursuant to Section 3.3(b) is greater than the difference between Final Working Capital shown in the independent accountant's calculation and NDC's calculation of Closing Working Capital delivered pursuant to Section 3.3(a), (ii) by NDC if the difference between Final Working Capital shown in the independent accountant's calculation and the NDC's calculation of Closing Working Capital delivered pursuant to Section 3.3(a) is greater than the difference between the Final Working Capital Ratio shown in the independent accountant's calculation and the Stockholder Representative's calculation of the Closing Working Capital Ratio delivered pursuant to Section 3.3(b), and (iii) otherwise equally by the Stockholders and NDC. (d) The Stockholder Representative and NDC agree that they will, and will cause their respective independent accountants and Source and its Subsidiaries to, cooperate and assist in the preparation of the Closing Balance Sheet and the calculation of Closing Working Capital, Closing Current Assets and Closing Current Liabilities and in the conduct of the reviews referred to in this Section 3.3, including, without limitation, making available, to the extent necessary, relevant books, records, working papers, analyses and schedules, and permitting representatives of the parties to consult with the respective employees, auditors, actuaries, attorneys and agents of Source and its Subsidiaries. 3.4 Adjustment of Purchase Price. (a) Subject To Section 3.4(c) Below, (i) If Final Current Assets are less than the product of 0.9416 times Final Current Liabilities (the amount of such shortfall referred to as, the "Final Working Capital Deficit"), the Stockholders shall pay to NDC the amount of the Final Working Capital Deficit as an adjustment to the Purchase Price, out of the Stock Escrow in the manner provided in the Escrow Agreement. (ii) If Final Current Assets are greater than the product of 0.9416 times Final Current Liabilities (the amount of such surplus referred to as, the "Final Working Capital Surplus"), NDC shall pay to the escrow agent, to be held in accordance with the Escrow Agreement, that number of shares of NDC Common Stock equal to the quotient of the Final Working Capital Surplus divided by the Average Closing Price as of the date Final Working Capital is determined. A-7 (iii) "Final Working Capital" means Closing Working Capital (i) as shown in NDC's calculation delivered pursuant to Section 3.3(a), if no notice of disagreement with respect thereto is duly delivered pursuant to Section 3.3(b); or (ii) if such a notice of disagreement is delivered, (A) as agreed by NDC and the Stockholder Representative pursuant to Section 3.3(b) or (B) in the absence of such agreement, as shown in the independent accountant's calculation delivered pursuant to Section 3.3(c); provided that, in no event shall Final Working Capital be (i) more than the Stockholder Representative's calculation of Closing Working Capital delivered pursuant to Section 3.3(b), if any, or (ii) less than the lesser of NDC's calculation of Closing Working Capital delivered pursuant to Section 3.3(a) or the Stockholder Representative's calculation of Closing Working Capital delivered pursuant to Section 3.3(b), if any. (b) Subject to Section 3.4(c) below, (i) If Total Current Assets are less than the product of 0.9975 times Total Current Liabilities (the "Total Working Capital Deficit"), then the Stockholders shall pay to NDC the Current Asset Allocation Amount as a further adjustment to the Purchase Price, out of the Stock Escrow in the manner provided in the Escrow Agreement. (ii) If Total Current Assets are greater than the product of 0.9975 times Total Current Liabilities (the "Total Working Capital Surplus"), then NDC shall pay to the Stockholders pursuant to the instructions of the Stockholder Representative, as a further adjustment to the Purchase Price, that number of shares of NDC Common Stock equal to the quotient of the Current Asset Allocation Amount divided by the Average Closing Price as of the date Final Working Capital is determined. (iii) As used herein, "Total Current Assets" shall mean the amount equal to the sum of Final Current Assets in this Agreement and Final Current Assets calculated pursuant to the PMSI Agreement; "Total Current Liabilities" shall mean the amount equal to the sum of Final Current Liabilities in this Agreement and Final Current Liabilities calculated pursuant to the PMSI Agreement; "Current Asset Allocation Amount" shall mean the amount equal to the product of (A) the quotient of Final Current Assets in this Agreement divided by Total Combined Assets multiplied by (B) the Total Working Capital Deficit or Total Working Capital Surplus, as the case may be; and "Total Combined Assets" shall mean the sum of Final Current Assets under this Agreement and Final Current Assets calculated under the PMSI Agreement. (c) For purposes of any adjustments to the Purchase Price made pursuant to this Section, the parties shall take into account any adjustment made to the Purchase Price at Closing pursuant to Section 3.2(c) hereof. 3.5 Anti-Dilution Provisions. In the event NDC changes the number of shares of NDC Common Stock issued and outstanding prior to the Effective Time as a result of a stock split, stock dividend, or similar recapitalization with respect to such stock and the record date therefor (in the case of a stock dividend) or the effective date thereof (in the case of a stock split or similar recapitalization for which a record date is not established) shall be prior to the Effective Time, the Common Exchange Ratios shall be proportionately adjusted. 3.6 Shares Held by Source or NDC. Each of the shares of Source Common Stock and Source Preferred Stock held by any Source Entity or by any NDC Entity shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefor. 3.7 Dissenting Stockholders. Any holder of shares of Source Common Stock or Source Preferred Stock who perfects his dissenters' rights in accordance with and as contemplated by Section 262 of the DGCL shall be entitled to receive the value of such shares in cash as determined pursuant to such provision of Law; provided, that no such payment shall be made to any dissenting stockholder unless and until such dissenting stockholder has complied with the applicable provisions of the DGCL and surrendered to Source the certificate or certificates representing the shares for which payment is being made. In the event that after the Effective Time a dissenting stockholder of Source fails to perfect, or effectively withdraws or loses, his right to appraisal and of payment for his shares, NDC shall issue and deliver the consideration to which such holder of shares of Source Common Stock or Source Preferred Stock is entitled under this Article 3 (without interest) upon surrender by such holder of the certificate or certificates representing shares of Source Common Stock or Source Preferred Stock held by A-8 him. If and to the extent required by applicable Law, Source will establish (or cause to be established) an escrow account with an amount sufficient to satisfy the maximum aggregate payment that may be required to be paid to dissenting stockholders. Upon satisfaction of all claims of dissenting stockholders, the remaining escrowed amount, reduced by payment of the fees and expenses of the escrow agent, will be returned to the Surviving Corporation. 3.8 Fractional Shares. Notwithstanding any other provision of this Agreement, each holder of shares of Source Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of NDC Common Stock (after taking into account all certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of NDC Common Stock multiplied by the market value of one share of NDC Common Stock at the Effective Time. The market value of one share of NDC Common Stock at the Effective Time shall be the closing price of such common stock on the NYSE- Composite Transactions List (as reported by The Wall Street Journal or, if not reported thereby, any other authoritative source selected by NDC) on the last trading day preceding the Effective Time. No such holder will be entitled to dividends, voting rights, or any other rights as a stockholder in respect of any fractional shares. ARTICLE 4 Exchange of Shares 4.1 Exchange Procedures. Promptly after the Effective Time, NDC and Source shall cause the exchange agent selected by NDC (the "Exchange Agent") to mail to each holder of record of a certificate or certificates which represented shares of Source Common Stock and Source Preferred Stock immediately prior to the Effective Time (the "Certificates") appropriate transmittal materials and instructions (which shall specify that delivery shall be effected, and risk of loss and title to such Certificates shall pass, only upon proper delivery of such Certificates to the Exchange Agent). The Certificate or Certificates of Source Common Stock or Source Preferred Stock so delivered shall be duly endorsed as the Exchange Agent may require. In the event of a transfer of ownership of shares of Source Common Stock or Source Preferred Stock represented by Certificates that are not registered in the transfer records of Source, the consideration provided in Section 3.1 may be issued to a transferee if the Certificates representing such shares are delivered to the Exchange Agent, accompanied by all documents required to evidence such transfer and by evidence satisfactory to the Exchange Agent that any applicable stock transfer taxes have been paid. If any Certificate shall have been lost, stolen, mislaid or destroyed, upon receipt of (i) an affidavit of that fact from the holder claiming such Certificate to be lost, mislaid, stolen or destroyed, (ii) such bond, security or indemnity as NDC and the Exchange Agent may reasonably require and (iii) any other documents necessary to evidence and effect the bona fide exchange thereof, the Exchange Agent shall issue to such holder the consideration into which the shares represented by such lost, stolen, mislaid or destroyed Certificate shall have been converted. The Exchange Agent may establish such other reasonable and customary rules and procedures in connection with its duties as it may deem appropriate. After the Effective Time, each holder of shares of Source Common Stock and Source Preferred Stock (other than shares to be canceled pursuant to Section 3.6 or as to which statutory dissenters' rights have been perfected as provided in Section 3.7) issued and outstanding at the Effective Time shall surrender the Certificate or Certificates representing such shares to the Exchange Agent and shall promptly upon surrender thereof receive in exchange therefor the consideration provided in Section 3.1, together with all undelivered dividends or distributions in respect of such shares (without interest thereon) pursuant to Section 4.2. To the extent required by Section 3.8, each holder of shares of Source Common Stock and Source Preferred Stock issued and outstanding at the Effective Time also shall receive, upon surrender of the Certificate or Certificates, cash in lieu of any fractional share of NDC Common Stock to which such holder may be otherwise entitled (without interest). NDC shall not be obligated to deliver the consideration to which any former holder of Source Common Stock or Source Preferred Stock is entitled as a result of the Merger until such holder surrenders such holder's Certificate or Certificates for exchange as provided in this Section 4.1. Any other provision of this Agreement notwithstanding, neither NDC, the Surviving Corporation nor the Exchange Agent shall be liable to a holder of Source Common A-9 Stock or Source Preferred Stock for any amounts paid or property delivered in good faith to a public official pursuant to any applicable abandoned property, escheat or similar Law. Adoption of this Agreement by the stockholders of Source shall constitute ratification of the appointment of the Exchange Agent. 4.2 Rights Of Former Source Stockholders. At the Effective Time, the stock transfer books of Source shall be closed as to holders of Source Common Stock and Source Preferred Stock immediately prior to the Effective Time and no transfer of Source Common Stock or Source Preferred Stock by any such holder shall thereafter be made or recognized. Until surrendered for exchange in accordance with the provisions of Section 4.1, each Certificate theretofore representing shares of Source Common Stock or Source Preferred Stock (other than shares to be canceled pursuant to Section 3.6) shall from and after the Effective Time represent for all purposes only the right to receive the consideration provided in Sections 3.1 and 3.8 in exchange therefor, subject, however, to the Surviving Corporation's obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time which have been declared or made by Source in respect of such shares of Source Common Stock or Source Preferred Stock in accordance with the terms of this Agreement and which remain unpaid at the Effective Time. Whenever a dividend or other distribution is declared by NDC on the NDC Common Stock, the record date for which is at or after the Effective Time, the declaration shall include dividends or other distributions on all shares of NDC Common Stock issuable pursuant to this Agreement, but no dividend or other distribution payable to the holders of record of NDC Common Stock as of any time subsequent to the Effective Time shall be delivered to the holder of any Certificate until such holder surrenders such Certificate for exchange as provided in Section 4.1. However, upon surrender of such Certificate, both the NDC Common Stock certificate (together with all such undelivered dividends or other distributions without interest) and any undelivered dividends and cash payments payable hereunder (without interest) shall be delivered and paid with respect to each share represented by such Certificate. 4.3 Escrow Agreement. In connection with the Closing, NDC and the Stockholder Representative shall have executed and delivered to the other an escrow agreement (the "Escrow Agreement"), which shall be in the form of Exhibit 1. The Stock Escrow to be paid pursuant to Section 3.1(c) shall be paid to and held by the escrow agent pursuant to the terms of the Escrow Agreement.

Subject to such requisite stockholder approval, this Agreement represents a legal, valid, and binding obligation of Source, enforceable against Source in accordance with its terms (except in all cases as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, receivership, conservatorship, moratorium, or similar Laws affecting the enforcement of creditors' rights generally and except that the availability of the equitable remedy of specific performance or injunctive relief is subject to the discretion of the court before which any proceeding may be brought). (b) Neither the execution and delivery of this Agreement by Source, nor the consummation by Source of the transactions contemplated hereby, nor compliance by Source with any of the provisions hereof, will (i) conflict with or result in a breach of any provision of Source's Certificate of Incorporation or Bylaws or the certificate or articles of incorporation or bylaws of any Source Subsidiary or any resolution adopted by the board of directors or the stockholders of any Source Entity, or (ii) except as disclosed in Section 5.2 of the Source Disclosure Memorandum, constitute or result in a Default under, or require any Consent pursuant to, or result in the creation of any Lien on any Asset of any Source Entity under, any material Contract or Permit of any Source Entity or, (iii) subject to receipt of the requisite Consents referred to in Section 9.1(b), constitute or result in a Default under, or require any Consent pursuant to, any Law or Order applicable to any Source Entity or any of their respective material Assets.

Except as specifically contemplated by this Agreement, no Person has any Contract or any right or privilege (whether pre-emptive or contractual) capable of becoming a Contract or Equity Right for the purchase, subscription or issuance of any securities of Source from Source. 5.4 Source Subsidiaries. Source has disclosed in Section 5.4 of the Source Disclosure Memorandum all of the Source Subsidiaries that are corporations (identifying its jurisdiction of incorporation, each jurisdiction in A-11 which it is qualified and/or licensed to transact business, and the number of shares owned and percentage ownership interest represented by such share ownership) and all of the Source Subsidiaries that are general or limited partnerships, limited liability companies, or other non-corporate entities (identifying the Law under which such entity is organized, each jurisdiction in which it is qualified and/or licensed to transact business, and the amount and nature of the ownership interest therein). Except as disclosed in Section 5.4 of the Source Disclosure Memorandum, Source or one of its wholly-owned Subsidiaries owns all of the issued and outstanding shares of capital stock (or other equity interests) of each Source Subsidiary. No capital stock (or other equity interest) of any Source Subsidiary is or may become required to be issued (other than to another Source Entity) by reason of any Equity Rights, and there are no Contracts by which any Source Subsidiary is bound to issue (other than to another Source Entity) additional shares of its capital stock (or other equity interests) or Equity Rights or by which any Source Entity is or may be bound to transfer any shares of the capital stock (or other equity interests) of any Source Subsidiary (other than to another Source Entity). There are no Contracts relating to the rights of any Source Entity to vote or to dispose of any shares of the capital stock (or other equity interests) of any Source Subsidiary. All of the shares of capital stock (or other equity interests) of each Source Subsidiary held by a Source Entity are fully paid and nonassessable under the applicable corporation Law of the jurisdiction in which such Subsidiary is incorporated or organized and are owned by the Source Entity free and clear of any Lien, except for the pledge by Source of the stock of one of its Subsidiaries to PMSI pursuant to that certain Securities Transfer Agreement, between PMSI and Source, (the "Source Divestiture Agreement"), which pledge will be released at Closing. Except as disclosed in Section 5.4 of the Source Disclosure Memorandum, each Source Subsidiary is duly organized, validly existing, and (as to corporations) in good standing under the Laws of the jurisdiction in which it is incorporated or organized, and has the corporate or other power and authority necessary for it to own, lease, and operate its Assets and to carry on its business as now conducted. Each Source Subsidiary is duly qualified or licensed to transact business as a foreign corporation or other entity, and in good standing in the States of the United States and foreign jurisdictions where the character of its Assets or the nature or conduct of its business requires it to be so qualified or licensed, except for such jurisdictions in which the failure to be so qualified or licensed is not reasonably likely to have, individually or in the aggregate, a Source Material Adverse Effect. The minute book and other organizational documents for each Source Subsidiary have been made available to NDC for its review, and, except as disclosed in Section 5.4 of the Source Disclosure Memorandum, are true and complete in all material respects as in effect as of the date of this Agreement and accurately reflect in all material respects all amendments thereto and all proceedings of the Board of Directors and stockholders thereof. Source has no Subsidiaries other than the Source Subsidiaries and the Source Divestiture Subsidiaries. 5.5 Financial Statements and Projections. (a) Each Of The Source Financial Statements (including, in each case, any related notes) was prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes to such financial statements), and fairly presented in all material respects the consolidated financial position of Source and its Subsidiaries, or Source and the Source Subsidiaries, as the case may be, as at the respective dates and the consolidated results of operations and cash flows for the periods indicated, except that the unaudited interim financial statements do not contain certain financial statement footnotes otherwise required by GAAP in full fiscal year financial statements and were or are subject to normal and recurring year-end adjustments, which were not or are not expected to be material in amount or effect. (b) Each of the Joint Venture Financial Statements (including, in each case, any related notes) was prepared in accordance with GAAP applied on a consistent basis throughout the periods involved (except as may be indicated in the notes to such financial statements), and fairly presented in all material respects the pro forma financial position of the Joint Venture as at the respective dates and the combined results of operations and cash flows for the periods indicated, except that the unaudited interim financial statements do not contain certain financial statement footnotes otherwise required by GAAP in full fiscal year financial statements and were or are subject to normal and recurring year-end adjustments which were not or are not expected to be material in amount or effect. A-12 (c) Set forth in Section 5.5 of the Source Disclosure Memorandum is a true and correct copy of the financial projections prepared by Source with respect to its results of operations, cash flows and capital expenditures through June 30, 1998, including a list of the principal assumptions underlying such projections. Source has prepared the projections in good faith and does not have any reason to believe that the assumptions used in preparing the projections are unrealistic under the circumstances. NDC acknowledges that the assumptions are subject to significant business and competitive uncertainties and are dependent upon future business decisions. Accordingly, the projections cannot be viewed as a guarantee of future performance by Source and no assurance can be given that the actual results of operations of Source will be comparable to those reflected in the projections. 5.6 Absence of Undisclosed Liabilities. Neither the Joint Venture nor any Source Entity has any Liabilities that are reasonably likely to have, individually or in the aggregate, a Source Material Adverse Effect, except Liabilities which are accrued or reserved against in the consolidated balance sheets of Source as of March 31, 1997, included in the Source Financial Statements delivered prior to the date of this Agreement, or reflected in the notes thereto or in the Joint Venture Financial Statements or reflected in the notes thereto.

Without limiting the generality of the foregoing, Source did not at the time of the spin-off have any plans or intentions of further transferring, exchanging or otherwise selling all or any part of the capital stock of Source or the Assets of Source.

No Source Entity is in Default under any of its Source Intellectual Property licenses. No proceedings have been instituted, or are pending or to the Knowledge of Source threatened, which challenge the rights of any Source Entity with respect to Source Intellectual Property used, sold or licensed by such Source Entity in the course of its business, nor has any person claimed or alleged any rights to such Source Intellectual Property.

(a) Source has disclosed in Section 5.14 of the Source Disclosure Memorandum, and has delivered or made available to NDC prior to the execution of this Agreement copies in each case of, all pension, retirement, profit- sharing, deferred compensation, stock option, employee stock ownership, severance pay, vacation, bonus, or other incentive plan, all other written employee programs, arrangements, or agreements, all medical, vision, dental, or other health plans, all life insurance plans, and all other employee benefit plans or fringe benefit plans, including "employee benefit plans" as that term is defined in Section 3(3) of ERISA, which is currently, or within the six (6) years preceding the Closing Date has been, adopted, maintained by, sponsored in whole or in part by, or contributed to by any Source Entity or ERISA Affiliate (including any entity which was an ERISA Affiliate during such six (6) year period) thereof for the benefit of employees, retirees, dependents, spouses, directors, independent contractors, or other beneficiaries and under which employees, retirees, dependents, spouses, directors, independent contractors, or other beneficiaries are eligible to participate (collectively, the "Source Benefit Plans"). Any of the Source Benefit Plans which is an "employee pension benefit plan," as that term is defined in Section 3(2) of ERISA, is referred to herein as a "Source ERISA Plan." Each Source ERISA A-16 Plan which is also a "defined benefit plan" (as defined in Section 414(j) of the Internal Revenue Code) is referred to herein as a "Source Pension Plan." No Source Pension Plan is or has been a multiemployer plan within the meaning of Section 3(37) of ERISA. (b) All Source Benefit Plans are in compliance with the applicable terms of ERISA, the Internal Revenue Code, and any other applicable Laws the breach or violation of which are reasonably likely to have, individually or in the aggregate, a Source Material Adverse Effect.

No Source Entity has engaged in a transaction with respect to any Source Benefit Plan that, assuming the taxable period of such transaction expired as of the date hereof, would subject any Source Entity to a Tax imposed by either Section 4975 of the Internal Revenue Code or Section 502(i) of ERISA.

Since the date of the most recent actuarial valuation, there has been (i) no material change in the financial position of any Source Pension Plan, (ii) no change in the actuarial assumptions with respect to any Source Pension Plan, and (iii) no increase in benefits under any Source Pension Plan as a result of plan amendments or changes in applicable Law which is reasonably likely to have, individually or in the aggregate, a Source Material Adverse Effect or materially adversely affect the funding status of any such plan. Neither any Source Pension Plan nor any "single-employer plan," within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any Source Entity, or the single- employer plan of any entity which is considered one employer with Source under Section 4001 of ERISA or Section 414 of the Internal Revenue Code or Section 302 of ERISA (whether or not waived) (an "ERISA Affiliate") has an "accumulated funding deficiency" within the meaning of Section 412 of the Internal Revenue Code or Section 302 of ERISA. No Source Entity has provided, or is required to provide, security to a Source Pension Plan or to any single- employer plan of an ERISA Affiliate pursuant to Section 401(a)(29) of the Internal Revenue Code. (d) No Liability under Subtitle C or D of Title IV of ERISA has been or is expected to be incurred by any Source Entity with respect to any ongoing, frozen, or terminated single-employer plan or the single-employer plan of any ERISA Affiliate. No Source Entity has incurred any withdrawal Liability with respect to a multiemployer plan under Subtitle B of Title IV of ERISA (regardless of whether based on contributions of an ERISA Affiliate). No notice of a "reportable event," within the meaning of Section 4043 of ERISA for which the 30-day reporting requirement has not been waived, has been required to be filed for any Source Pension Plan or by any ERISA Affiliate within the 12-month period ending on the date hereof. (e) Except as disclosed in Section 5.14 of the Source Disclosure Memorandum, no Source Entity has any Liability for retiree health and life benefits under any of the Source Benefit Plans and there are no restrictions on the rights of such Source Entity to amend or terminate any such retiree health or benefit Plan without incurring any Liability thereunder. (f) Except as disclosed in Section 5.14 of the Source Disclosure Memorandum, neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will (i) result in any payment (including severance, unemployment compensation, golden parachute, or otherwise) becoming due to any director or any employee of any Source Entity from any Source Entity under any Source Benefit Plan or otherwise, (ii) increase any benefits otherwise payable under any Source Benefit Plan, or (iii) result in any acceleration of the time of payment or vesting of any such benefit. (g) The actuarial present values of all accrued deferred compensation entitlements (including entitlements under any executive compensation, supplemental retirement, or employment agreement) of employees and former employees of any Source Entity and their respective beneficiaries, other than entitlements accrued pursuant to funded retirement plans subject to the provisions of Section 412 of the Internal Revenue Code or A-17 Section 302 of ERISA, have been fully reflected on the Source Financial Statements to the extent required by and in accordance with GAAP. (h) Neither NDC nor any ERISA Affiliate of NDC shall have any liability or obligation with respect to (i) employment-related liabilities, whether contingent or otherwise, arising out of any individual's employment or working relationship with any ERISA Affiliate of Source or any other entity which participated in or contributed to any Source ERISA Plan other than Source or any Source Subsidiary; or (ii) any benefit plan, program, arrangement or policy maintained or contributed to by any ERISA Affiliate of Source other than Source or any Source Subsidiary. 5.15 Material Contracts.

A-24 7.3 Covenants of NDC. From the date of this Agreement until the earlier of the Effective Time or the termination of this Agreement, unless the prior written consent of Source shall have been obtained, and except as otherwise expressly contemplated herein, NDC covenants and agrees that it shall (a) continue to conduct its business and the business of its Subsidiaries in a manner designed, in its reasonable judgment, to enhance the long-term value of the NDC Common Stock and the business prospects of the NDC Entities and to the extent consistent therewith use all reasonable efforts to preserve intact the NDC Entities' core businesses and goodwill with their respective employees and the communities they serve, and (b) take no action which would (i) materially adversely affect the ability of any Party to obtain any Consents required for the transactions contemplated hereby without imposition of a condition or restriction of the type referred to in the last sentences of Section 9.1(b) or 9.1(c), or (ii) materially adversely affect the ability of any Party to perform its covenants and agreements under this Agreement; provided, that the foregoing shall not prevent any NDC Entity from acquiring any Assets or other businesses or from discontinuing or disposing of any of its Assets or business if such action is, in the judgment of NDC, desirable in the conduct of the business of NDC and its Subsidiaries, provided that such actions shall not materially delay the Effective Time or materially hinder consummation of the Merger. NDC further covenants and agrees that it will not, without the prior written consent of Source, which consent shall not be unreasonably withheld, amend the Certificate of Incorporation or Bylaws of NDC or, except as expressly contemplated by this Agreement, the NDC Rights Agreement, in each case, in any manner adverse to the holders of Source Common Stock as compared to rights of holders of NDC Common Stock generally as of the date of this Agreement. 7.4 Adverse Changes in Condition. Each Party agrees to give written notice promptly to the other Party upon becoming aware of the occurrence or impending occurrence of any event or circumstance relating to it or any of its Subsidiaries which (i) is reasonably likely to have, individually or in the aggregate, a Source Material Adverse Effect or a NDC Material Adverse Effect, as applicable, or (ii) would cause or constitute a material breach of any of its representations, warranties, or covenants contained herein, and to use its reasonable efforts to prevent or promptly to remedy the same. 7.5 Reports.

As of their respective dates, such reports filed with the SEC will comply in all material respects with the Securities Laws and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. Any financial statements contained in any other reports to another Regulatory Authority shall be prepared in accordance with Laws applicable to such reports.

Each Party shall use, and shall cause each of its Subsidiaries to use, its reasonable efforts to obtain all Consents necessary or desirable for the consummation of the transactions contemplated by this Agreement. 8.6 Investigation and Confidentiality.

Prior to the Effective Time, Source and NDC shall consult with each other as to the form and substance of any press release or other public disclosure materially related to this Agreement or any other transaction contemplated hereby; provided, that nothing in this Section 8.7 shall be deemed to prohibit any Party from making any disclosure which its counsel deems necessary or advisable in order to satisfy such Party's disclosure obligations imposed by Law. 8.8 Certain Actions. Except with respect to this Agreement and the transactions contemplated hereby, no Source Entity nor any Stockholder nor any Affiliate thereof nor any Representatives thereof retained by any Source Entity shall directly or indirectly solicit any Acquisition Proposal by any Person. Except to the extent the Board of Directors of Source, after having consulted with and considered the advice of outside counsel, reasonably determines in good faith that the failure to take such actions would constitute a breach of fiduciary duties of the members of such Board of Directors to Source's stockholders under applicable law, no Source Entity, any Stockholder or any Affiliate or Representative thereof shall furnish any non- public information that it is not legally obligated to furnish, negotiate with respect to, or enter into any Contract with respect to, any Acquisition Proposal, but Source may communicate information about such an Acquisition Proposal to its stockholders if and to the extent that it is required to do so in order to comply with its legal obligations as advised by outside counsel. Each Stockholder and Source shall promptly advise NDC following the receipt of any Acquisition Proposal and the details thereof, and advise NDC of any developments with respect to such Acquisition Proposal promptly upon the occurrence thereof. Each Stockholder and Source shall (i) immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Persons conducted heretofore with respect to any of the foregoing, and (ii) direct and use its reasonable efforts to cause all of its Affiliates and Representatives not to engage in any of the foregoing. 8.9 Tax Treatment. NDC undertakes and agrees to use its reasonable efforts to cause the Merger, and to take no action which would cause the Merger not, to qualify for or as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code for federal income tax purposes. 8.10 State Takeover Laws. Each Source Entity shall take all necessary steps to exempt the transactions contemplated by this Agreement from, or if necessary to challenge the validity or applicability of, any applicable Takeover Law, including Section 203 of the DGCL. 8.11 Charter Provisions. Each Source Entity shall take all necessary action to ensure that the entering into of this Agreement and the consummation of the Merger and the other transactions contemplated hereby do not and will not result in the grant of any rights to any Person under the Certificate of Incorporation, Bylaws or other governing instruments of any Source Entity or restrict or impair the ability of NDC or any of its A-27 Subsidiaries to vote, or otherwise to exercise the rights of a stockholder with respect to, shares of any Source Entity that may be directly or indirectly acquired or controlled by them. 8.12 Agreement of Affiliates. Source has disclosed in Section 8.12 of the Source Disclosure Memorandum all Persons whom it reasonably believes is an "affiliate" of Source for purposes of Rule 145 under the 1933 Act. Source shall use its reasonable efforts to cause each such Person to deliver to NDC not later than 30 days after the date of this Agreement, a written agreement, substantially in the form of Exhibit 3, providing that such Person will not sell, pledge, transfer, or otherwise dispose of the shares of Source Common Stock or Source Preferred Stock held by such Person except as contemplated by such agreement or by this Agreement and will not sell, pledge, transfer, or otherwise dispose of the shares of NDC Common Stock to be received by such Person upon consummation of the Merger except in compliance with applicable provisions of the 1933 Act and the rules and regulations thereunder. NDC shall be entitled to place restrictive legends upon certificates for shares of NDC Common Stock issued to affiliates of Source pursuant to this Agreement to enforce applicable provisions of Law. NDC shall not be required to maintain the effectiveness of the Registration Statement under the 1933 Act for the purposes of resale of NDC Common Stock by such affiliates. 8.13 Employee Benefits and Contracts. Following The Effective Time, NDC shall provide generally to officers and employees of the Source Entities employee benefits under employee benefit and welfare plans on terms and conditions which when taken as a whole are substantially similar to those currently provided by the NDC Entities to their similarly situated officers and employees. For purposes of participation, vesting and (except in the case of NDC retirement plans) benefit accrual under NDC's employee benefit plans, the service of the employees of the Source Entities prior to the Effective Time shall be treated as service with a NDC Entity participating in such employee benefit plans. NDC also shall cause the Surviving Corporation and its Subsidiaries to honor in accordance with their terms all employment, severance, consulting and other compensation Contracts disclosed in Section 8.13 of the Source Disclosure Memorandum to NDC between any Source Entity and any current or former director, officer, or employee thereof, and all provisions for vested benefits or other vested amounts earned or accrued through the Effective Time under the Source Benefit Plans. If so advised by NDC at least 30 days prior to the Effective Time, Source, on behalf of itself and each Source Entity, shall terminate its participation in the Source Informatics America, PMSI Scott-Levin, and Walsh America Retirement Plan (the "401(k) Plan"), effective no later than the day preceding the Effective Time. The amendment to the 401(k) Plan which effects such termination shall be adopted no later than ten (10) days prior to the Effective Time. Immediately following its adoption, Source shall provide NDC with a copy of such amendment which (i) terminates Source's participation in the plan, (ii) fully vests employees of each Source Entity in their account balances under the 401(k) Plan as of the effective date of the termination; and (iii) provides for lump sum distributions (which shall be "eligible rollover distributions," within the meaning of Section 402(c)(4) of the Internal Revenue Code) of the participants' accrued benefits as soon as practicable following Source's or its successor's receipt of a letter from the Internal Revenue Service to the effect that the Source Entities' termination of participation in the 401(k) Plan and the subsequent distribution of the participants' accounts thereunder does not adversely affect the 401(k) Plan's qualified status under Section 401(a) of the Internal Revenue Code. The effectiveness of Source's termination of its participation in the 401(k) Plan may be contingent upon the receipt of such a letter from the IRS. Under no circumstances may an employee of any Source Entity, prior to the receipt of such a determination letter, receive a distribution from the 401(k) Plan on account of Source's termination of its participation in the plan. 8.14 Indemnification. (a) Except as set forth in the Waivers, for a period of six years after the Effective Time, NDC shall, and shall cause the Surviving Corporation to, indemnify, defend and hold harmless the present and former directors, officers, employees and agents of the Source Entities (each, an "Indemnified Party") against all Liabilities arising out of actions or omissions arising out of the Indemnified Party's service or services as directors, officers, employees or agents of Source or, at Source's request, of another corporation, partnership, joint venture, trust or other enterprise occurring at or prior to the Effective Time to the fullest extent permitted under Delaware Law and by Source's Certificate of Incorporation and Bylaws as in effect on the date hereof, including provisions A-28 relating to advances of expenses incurred in the defense of any Litigation and whether or not any NDC Entity is insured against any such matter. Without limiting the foregoing, in any case in which approval by the Surviving Corporation is required to effectuate any indemnification, the Surviving Corporation shall direct, at the election of the Indemnified Party, that the determination of any such approval shall be made by independent counsel mutually agreed upon between NDC and the Indemnified Party. (b) NDC shall, or shall cause the Surviving Corporation to, use its reasonable efforts (and Source shall cooperate prior to the Effective Time in these efforts) to maintain in effect for a period of three years after the Effective Time Source's existing directors' and officers' liability insurance policy (provided that NDC may substitute therefor (i) policies of at least the same coverage and amounts containing terms and conditions which are substantially no less advantageous or (ii) with the consent of Source given prior to the Effective Time, any other policy) with respect to claims arising from facts or events which occurred prior to the Effective Time and covering persons who are currently covered by such insurance; provided, that neither NDC nor the Surviving Corporation shall be obligated to make aggregate premium payments for such three-year period in respect of such policy (or coverage replacing such policy) which exceed, for the portion related to Source's directors and officers, 150% of the annual premium payments on Source's current policy in effect as of the date of this Agreement (the "Maximum Amount"). If the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, NDC shall use its reasonable efforts to maintain the most advantageous policies of directors' and officers' liability insurance obtainable for a premium equal to the Maximum Amount. Prior to the Closing Date, NDC shall provide Source with an estimate of the costs associated with maintaining a directors' and officers' liability insurance policy as discussed above, which estimate shall have been prepared by an independent third party and which amount shall be listed as a Transaction Expense on Schedule 1 hereof. (c) Any Indemnified Party wishing to claim indemnification under paragraph (a) of this Section 8.14, upon learning of any such Liability or Litigation, shall promptly notify NDC thereof. In the event of any such Litigation (whether arising before or after the Effective Time), (i) NDC or the Surviving Corporation shall have the right to assume the defense thereof and neither NDC nor the Surviving Corporation shall be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if NDC or the Surviving Corporation elects not to assume such defense or counsel for the Indemnified Parties advises that there are substantive issues which raise conflicts of interest between NDC or the Surviving Corporation and the Indemnified Parties, the Indemnified Parties may retain counsel satisfactory to them, and NDC or the Surviving Corporation shall pay all reasonable fees and expenses of such counsel for the Indemnified Parties promptly as statements therefor are received; provided, that NDC and the Surviving Corporation shall be obligated pursuant to this paragraph (c) to pay for only one firm of counsel for all Indemnified Parties in any jurisdiction, (ii) the Indemnified Parties will cooperate in the defense of any such Litigation, and (iii) neither NDC nor the Surviving Corporation shall be liable for any settlement effected without its prior written consent; and provided further that neither NDC nor the Surviving Corporation shall have any obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction shall determine, and such determination shall have become final, that the indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable Law. (d) If NDC or the Surviving Corporation or any successors or assigns shall consolidate with or merge into any other Person and shall not be the continuing or surviving Person of such consolidation or merger or shall transfer all or substantially all of its assets to any Person, then and in each case, proper provision shall be made so that the successors and assigns of NDC or the Surviving Corporation shall assume the obligations set forth in this Section 8.14. (e) The provisions of this Section 8.14 are intended to be for the benefit of and shall be enforceable by, each Indemnified Party and its respective heirs and representatives. 8.15 Transaction Expenses. NDC agrees that it will cause Source to pay the Transaction Expenses when due and payable.

ARTICLE 10 Indemnification 10.1 Agreement of Indemnitors to Indemnify. Subject to the terms and conditions of this Article 10, Indemnitors jointly and severally agree to indemnify, defend, and hold harmless Indemnitees, and each of them, from, against, for and in respect of any and all Losses asserted against, or paid, suffered or incurred by, an Indemnitee and resulting from, based upon, or arising out of: (a) the inaccuracy, untruth, incompleteness or breach of any representation or warranty of any Indemnitor or Source contained in or made pursuant to this Agreement or in any certificate, Schedule, or Exhibit furnished by Indemnitors or Source in connection herewith (except that Source shall not be obligated to indemnify NDC for Losses arising out of the termination or cancellation of a Source Contract by a third party prior to Closing; provided that such termination or cancellation was not due to any breach of such Contract by Source), and for purposes of this Section 10.1(a) any qualification of such representations and warranties by reference to the materiality of matters stated therein or as to matters having or not having a "Material Adverse Effect,", and any limitation of such representations and warranties as being "to the knowledge of," or "known to" or words of similar effect, shall be disregarded, in determining any inaccuracy, untruth, incompleteness or breach thereof; (b) a breach of or failure to perform any covenant or agreement of Indemnitors or Source made in this Agreement; (c) any and all Taxes arising out of or associated with the Divestiture, as provided in Section 7.1(b) and determined as provided in Section 10.12; (d) any and all Taxes arising out of or associated with the matters set forth on Section 5.8(a)(ii) of the Source Disclosure Memorandum to the extent that, after using commercially reasonable efforts, NDC has been unable to collect such amounts from Walsh International Inc. or the customers involved in the transactions resulting in such Taxes; provided that NDC shall not pay such amounts to the applicable governmental authorities without direct assessment, or similar notice, from such authority directing payment thereof; or (e) any and all Losses relating to the matter set forth in Section 5.16(2) of the Source Disclosure Memorandum. 10.2 Procedures for Indemnification. (a) An Indemnification Claim shall be made by an Indemnitee by delivery of a written notice to the Stockholder Representative requesting indemnification and specifying the basis on which indemnification is sought and the amount of asserted Losses and, in the case of a Third Party Claim, containing (by attachment or otherwise) such other information as such Indemnitee shall have concerning such Third Party Claim. (b) If the Indemnification Claim involves a Third Party Claim the procedures set forth in Section 10.3 shall be observed by the Indemnitee and the Stockholder Representative. (c) If the Indemnification Claim involves a matter other than a Third Party Claim, the Stockholder Representative shall have 30 days to object to such Indemnification Claim by delivery of a written notice of such objection to such Indemnitee specifying in reasonable detail the basis for such objection. Failure to timely so object shall constitute a final and binding acceptance of the Indemnification Claim by the Stockholder Representative on behalf of all Indemnitors, and the Indemnification Claim shall be paid in accordance with subsection (d) hereof. If an objection is timely interposed by the Stockholder Representative and the dispute is A-33 not resolved by such Indemnitee and the Stockholder Representative within 15 days from the date the Indemnitee receives such objection, such dispute shall be resolved by arbitration as provided in Section 10.11. (d) Upon determination of the amount of an Indemnification Claim, whether by agreement between the Stockholder Representative and the Indemnitee or by an arbitration award or by any other final adjudication, such Indemnification Claim shall be paid out of the Stock Escrow pursuant to the provisions of the Escrow Agreement. 10.3 Third Party Claims. The obligations and liabilities of the parties hereunder with respect to a Third Party Claim shall be subject to the following terms and conditions: (a) The Indemnitee shall give the Stockholder Representative written notice of a Third Party Claim promptly after receipt by the Indemnitee of notice thereof, and the Stockholder Representative, on behalf of the Indemnitors, may undertake the defense, compromise and settlement thereof by representatives of its own choosing reasonably acceptable to the Indemnitee. The failure of the Indemnitee to notify the Stockholder Representative of such claim shall not relieve the Indemnitors of any liability that they may have with respect to such claim except to the extent the Stockholder Representative demonstrates that the defense of such claim is prejudiced by such failure. The assumption of the defense, compromise and settlement of any such Third Party Claim by the Stockholder Representative shall be an acknowledgment of the obligation of the Indemnitors to indemnify the Indemnitee with respect to such claim hereunder. If the Indemnitee desires to participate in, but not control, any such defense, compromise and settlement, it may do so at its sole cost and expense. If, however, the Stockholder Representative fails or refuses to undertake the defense of such Third Party Claim within ten (10) days after written notice of such claim has been given to the Stockholder Representative by the Indemnitee, the Indemnitee shall have the right to undertake the defense, compromise and settlement of such claim with counsel of its own choosing. In the circumstances described in the preceding sentence, the Indemnitee shall, promptly upon its assumption of the defense of such claim, make an Indemnification Claim as specified in Section 10.2 which shall be deemed an Indemnification Claim that is not a Third Party Claim for the purposes of the procedures set forth herein. For purposes of this paragraph, the Stockholder Representative shall be deemed to have received notice of the claim specified in Section 5.16(2) of the Source Disclosure Memorandum and to have agreed to assume the defense thereof following the Closing; provided, however, that such claim is still subject to the provisions of Section 10.7 hereof. (b) If, in the reasonable opinion of the Indemnitee, any Third Party Claim or the litigation or resolution thereof involves an issue or matter which could have a material adverse effect on the business, operations, assets, properties or prospects of the Indemnitee (including, without limitation, the administration of the tax returns and responsibilities under the tax laws of the Indemnitee), the Indemnitee shall have the right to control the defense, compromise and settlement of such Third Party Claim undertaken by the Stockholder Representative, and the costs and expenses of the Indemnitee in connection therewith shall be included as part of the indemnification obligations of the Indemnitors hereunder. If the Indemnitee shall elect to exercise such right, the Stockholder Representative shall have the right to participate in, but not control, the defense, compromise and settlement of such Third Party Claim at its sole cost and expense. (c) No settlement of a Third Party Claim involving the asserted liability of the Indemnitors under this Article shall be made without the prior written consent by or on behalf of the Stockholder Representative, which consent shall not be unreasonably withheld or delayed. Consent shall be presumed in the case of settlements of $20,000 or less where the Stockholder Representative has not responded within five business days of notice of a proposed settlement. If the Stockholder Representative assumes the defense of such a Third Party Claim, (a) no compromise or settlement thereof may be effected by the Stockholder Representative without the Indemnitee's consent unless (i) there is no finding or admission of any violation of law or any violation of the rights of any person and no effect on any other claim that may be made against the Indemnitee, (ii) the sole relief provided is monetary damages that are paid in full by the Indemnitors, and (iii) the compromise or settlement includes, as an unconditional term thereof, the giving by the claimant or the plaintiff to the Indemnitee of a release, in form and substance satisfactory to the Indemnitee, from all A-34 liability in respect of such Third Party Claim, and (b) the Indemnitee shall have no liability with respect to any compromise or settlement thereof effected without its consent. (d) In connection with the defense, compromise or settlement of any Third Party Claim, the parties to this Agreement shall execute such powers of attorney as may reasonably be necessary or appropriate to permit participation of counsel selected by any party hereto and, as may reasonably be related to any such claim or action, shall provide access to the counsel, accountants and other representatives of each party during normal business hours to all properties, personnel, books, tax records, contracts, commitments and all other business records of such other party and will furnish to such other party copies of all such documents as may reasonably be requested (certified, if requested). 10.4 Other Rights and Remedies Not Affected. The rights of the Indemnitees under this Article 10 are independent of and in addition to such rights and remedies as the Indemnitees may have at law or in equity or otherwise based upon any inaccuracy, untruth, incompleteness or breach of any representation or warranty of any Indemnitor contained herein or in any certificate, schedule or exhibit furnished by such party in connection herewith, or based upon the failure of an Indemnitor to perform any covenant, agreement or undertaking required by the terms hereof to be performed by such Indemnitor, including without limitation the right to seek specific performance, recession or restitution, none of which rights or remedies shall be affected or diminished hereby. 10.5 Survival. Subject to the time limitations set forth in Section 10.6 below, all representations, warranties and agreements contained in this Agreement or in any certificate delivered pursuant to this Agreement shall survive the Closing notwithstanding any investigation conducted with respect thereto or any knowledge acquired as to the accuracy or inaccuracy of any such representation or warranty. 10.6 Time Limitations. The Indemnitors will have no liability to the Indemnitees under or in connection with a breach of any of the representations, warranties, covenants or agreements made or to be performed by the Indemnitors or Source contained in this Agreement unless written notice asserting an Indemnification Claim based thereon is given to the Stockholder Representative prior to August 31, 1999. 10.7 Limitations as to Amount. (a) Indemnitors shall have no liability with respect to the matters described in Section 10.1 (other than the agreements in Sections 3.2 and 3.4) until the total of all Losses with respect thereto exceeds $200,000 in which event Indemnitors shall be obligated to indemnify the Indemnitees as provided in this Article 10 for all such Losses; provided, however, that each individual claim of $10,000 or less shall not be indemnifiable, and shall not be includable in determining whether the $200,000 threshold has been reached. (b) In no event shall the aggregate liability of the Indemnitors under this Article 10 exceed the lesser of (i) the Aggregate Value (as defined in the Escrow Agreement) of the Indemnification Escrow Amount (as defined in the Escrow Agreement), and (ii) $20,000,000. 10.8 Tax Effect and Insurance. The liability of the Indemnitors with respect to any Indemnification Claim shall be reduced by the tax benefit actually realized and any insurance proceeds received by the Indemnitees as a result of any Losses upon which such Indemnification Claim is based, and shall include any tax detriment actually suffered by the Indemnitees as a result of such Losses or the claims hereunder. The amount of any such tax benefit or detriment shall be determined by taking into account the effect, if any and to the extent determinable, of timing differences resulting from the acceleration or deferral of items of gain or loss resulting from such Losses and shall otherwise be determined so that payment by the Indemnitors of the Indemnification Claim, as adjusted to give effect to any such tax benefit or detriment, will make the Indemnitee as economically whole as is reasonably practical with respect to the Losses upon which the Indemnification Claim is based. Any dispute as to the amount of such tax benefit or detriment shall be resolved by arbitration as provided in Section 10.11 of this Agreement. A-35 10.9 Subrogation. Upon payment in full of any Indemnification Claim, whether such payment is effected by set-off or otherwise, or the payment of any judgment or settlement with respect to a Third Party Claim, the Indemnitors shall be subrogated to the extent of such payment to the rights of the Indemnitee against any person or entity with respect to the subject matter of such Indemnification Claim or Third Party Claim. 10.10 Appointment of Stockholder Representative. Each Indemnitor constitutes and appoints the Stockholder Representative as his or her true and lawful attorney-in-fact to act for and on behalf of such Indemnitor in all matters relating to or arising out of this Article 10 and the liability or asserted liability of such Indemnitor hereunder, including specifically, but without limitation, accepting and agreeing to the liability of such Indemnitor with respect to any Indemnification Claim, objecting to any Indemnification Claim, disputing the liability of such Indemnitor, or the amount of such liability, with respect to any Indemnification Claim and prosecuting and resolving such dispute as herein provided, accepting the defense, compromise and settlement of any Third Party Claim on behalf of such Indemnitor or refusing to accept the same, settling and compromising the liability of such Indemnitor hereunder, instituting and prosecuting such actions (including arbitration proceedings) as the Stockholder Representative shall deem appropriate in connection with any of the foregoing, retaining counsel, accountants, appraisers and other advisers in connection with any of the foregoing, all for the account of the Indemnitor, such Indemnitor agreeing to be fully bound by the acts, decisions and agreements of the Stockholder Representative taken and done pursuant to the authority herein granted. Each Indemnitor hereby agrees to indemnify and to save and hold harmless the Stockholder Representative from any liability incurred by the Stockholder Representative based upon or arising out of any act, whether of omission or commission, of the Stockholder Representative pursuant to the authority herein granted, other than acts, whether of omission or commission, of the Stockholder Representative that constitute gross negligence or willful misconduct in the exercise by the Stockholder Representative of the authority herein granted. 10.11 Arbitration. All disputes arising under this Article 10 (other than claims in equity) shall be resolved by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association. Arbitration shall be by a single arbitrator experienced in the matters at issue and selected by the Stockholder Representative and NDC in accordance with the Commercial Arbitration Rules of the American Arbitration Association. The arbitration shall be held in such place in Washington, D.C. as may be specified by the arbitrator (or any place agreed to by the Stockholder Representative, NDC and the arbitrator). The decision of the arbitrator shall be final and binding as to any matters submitted under this Article 10; provided, however, if necessary, such decision and satisfaction procedure may be enforced by either the Stockholder Representative or NDC in any court of record having jurisdiction over the subject matter or over any of the parties to this Agreement. All costs and expenses incurred in connection with any such arbitration proceeding (including reasonable attorneys fees) shall be borne by the party against which the decision is rendered, or, if no decision is rendered, such costs and expenses shall be borne equally by the Indemnitors as one party and the Indemnitees as the other party. If the arbitrator's decision is a compromise, the determination of which party or parties bears the costs and expenses incurred in connection with any such arbitration proceeding shall be made by the arbitrator on the basis of the arbitrator's assessment of the relative merits of the parties' positions. 10.12 Divestiture Taxes. (a) For purposes of 10.1(c) above, a "Tax" shall mean any federal, state, local or foreign Tax and shall be determined by assuming (i) that the only net operating loss available to offset income or gain related to the Divestiture is equal to 30% of the combined net operating loss of the Source Entities computed as of the Closing Date (determined by assuming that Tax Returns would have been filed for a period ending on the Closing Date and exclusive of any loss related to the Divestiture), and (ii) that such Tax attributable to the Divestiture is represented by the difference between (x) the Tax liability of Source for a hypothetical reporting period ending on the Closing Date and including the Divestiture computed based on the assumption contained in paragraph (i), and (y) the Tax liability of Source for such a period computed assuming that no taxable income or gain had resulted from the Divestiture. A-36 (b) Tax Returns for any period including the Divestiture shall be prepared by NDC and subject to review and approval of the Stockholder Representative with respect to the treatment of the Divestiture in the Tax Returns and the determination of the combined net operating loss of the Source Entities.

If Source elects to refuse to consummate the Merger pursuant to this Section 11.1(h), it shall give written notice thereof to NDC not later than two trading days following the Determination Date. During the five-day period commencing with its receipt of such notice, NDC shall have the option, in its sole discretion, to elect to revise the Common Exchange Ratios to equal that fraction of a share of NDC Common Stock (rounded to the nearest ten thousandth of a share) obtained by dividing the product of the Common Base Exchange Ratio or the Common Escrow Exchange Ratio, as the case may be, and the Lower Threshold Price by the Average Closing Price at the Determination Date. If NDC makes an election contemplated by the preceding sentence, within such five-day period, it shall give prompt written notice to Source of such election and the revised Common Exchange Ratios, whereupon the condition to consummation provided in this Section 11.1(h) shall be deemed to be satisfied and this Agreement shall remain in effect in accordance with its terms (except as the Common Exchange Ratios shall have been so modified), and any references in this Agreement to "Common Exchange Ratios" shall thereafter be deemed to refer to the Common Exchange Ratios as adjusted pursuant to this Section 11.1(h); or (i) By Source in the event that Source has entered into negotiations with a third party in accordance with Sections 8.1 and 8.8 of this Agreement, and pursuant to the continuing fiduciary duties of the Source's Board of Directors as required by applicable Law, Source has entered into a binding Acquisition Proposal with a third party. 11.2 Effect of Termination.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to Sections 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except: (a) shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof; (b) shares of stock of any other corporation or depository receipts in respect thereof, which shares of stock or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders; (c) cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or (d) any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph. (3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under Section 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation. (c) Any corporation may provide in its certificate of incorporation that appraisal rights under this Section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this Section, including those set forth in subsections (d) and (e), shall apply as nearly as is practicable. B-2 (d) Appraisal rights shall be perfected as follows: (1) If a proposed merger or consolidation for which appraisal rights are provided under this Section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsections (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this Section. Each stockholder electing to demand the appraisal of his shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of his shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of his shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or (2) If the merger or consolidation was approved pursuant to Section 228 or Section 253 of this title, each constituent corporation, either before the effective date of the merger or consolidation or within 10 days thereafter, shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all of the shares of the constituent corporation, and shall include in such notice a copy of this Section; provided that, if the notice is given on or after the effective date of the merger or consolidation, such notice shall be given by the surviving or resulting corporation to all such holders of any class or series of stock of a constituent corporation that are entitled to appraisal rights. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of the notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary and assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given. (e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with the provisions of subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw his B-3 demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after his written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later. (f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by one or more publications at least one week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publications shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation. (g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this Section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. (h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted his certificates of stock to the Register in Chancery, if such is required, may participate in all proceedings until it is finally determined that he is not entitled to appraisal rights under this section. (i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state. B-4 (j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal. (k) From and after the effective date of the merger or consolidation, no stockholder who has demanded his appraisal rights as provided in subsection (d) of this Section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this Section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of his demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this Section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just. (l) The shares of the surviving or resulting corporation into which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

The Escrow Amount subject to this Agreement shall be adjusted as follows: If, between the date of this Agreement and the Distribution Date with respect to the Working Capital Escrow Amount, NDC shall be entitled to an adjustment pursuant to Section 3.4 of the Merger Agreement (an "Adjustment Claim"), then NDC shall deliver to the Escrow Agent a notice thereof (a "Notice of Obligation") setting forth the Adjustment Claim amount, and upon receipt of such Notice of Obligation by the Escrow Agent, (i) the Escrow Agent shall distribute to NDC from the Escrow Amount an amount in cash, in immediately available funds, equal to such Adjustment Claim, and, if the Escrow Amount does not contain any cash, or contains an amount of cash insufficient to satisfy the Adjustment Claim, then C-3 (ii) the Escrow Agent shall distribute to NDC from the Escrow Amount that number of shares of NDC Common Stock equal to the quotient (rounded to the next highest whole number) obtained by dividing the amount of the Adjustment Claim not paid in cash pursuant to Section 3.2(i) above, by the Average Closing Price as of the date Final Working Capital is determined pursuant to Section 3.3(b) of the Merger Agreement. 3.3 Distribution of Working Capital Escrow Amount. If the adjustment provided for in Section 3.4 of the Merger Agreement is pending as of the Distribution Date with respect to the Working Capital Escrow Amount, the disputed Adjustment Claim (the "Disputed Working Capital Escrow Amount") for purposes of the calculations in the following sentence of this Section 3.3 shall be based on the Closing Balance Sheets prepared by NDC pursuant to Section 3.3(a) of the Merger Agreement and Section 1.3(a) of the PMSI Agreement, and equal to the sum of (i) the Final Working Capital Deficit, and (ii) the Current Asset Allocation Amount. Upon determination of the Disputed Working Capital Escrow Amount in accordance with the preceding sentence, the Escrow Agent shall promptly deliver to the Stockholders a distribution of cash, if any, in immediately available funds, and shares of NDC Common Stock from the Working Capital Escrow Amount, equal to the difference between the Aggregate Value as of the Distribution Date of the Working Capital Escrow Amount and the aggregate Disputed Working Capital Escrow Amount with respect to the pending Adjustment Claim (the "Undisputed Working Capital Escrow Amount"), and such amount shall be paid to the respective Stockholders in accordance with their respective Percentage Interests. Any delivery of NDC Common Stock to Stockholders shall be of full shares and any fractional portions shall be rounded to a whole number by the Escrow Agent so that the number of shares remaining in escrow to be delivered will be fully allocated among such Stockholders. Upon the final resolution as agreed by NDC and the Stockholder Representative in writing of the amount of the Adjustment Claim (the "Final Claim Amount") for which a Disputed Working Capital Escrow Amount was retained in escrow after the Distribution Date, the Escrow Agent shall promptly distribute to NDC an amount in cash, if any, in immediately available funds, and shares of NDC Common Stock from the Escrow Amount with an Aggregate Value as of the date of final resolution equal to the Final Claim Amount and shall deliver any remaining Disputed Working Capital Escrow Amount to the Stockholders in accordance with their respective Percentage Interests. 3.4 Adjustment of Indemnification Escrow Amount.

If there are Indemnification Claims pending as of the Distribution Date with respect to the Indemnification Escrow Amount, the amount of Losses under such disputed Indemnification Claims (the "Disputed Indemnification Escrow Amount") for purposes of the calculations in the following sentence of this Section 3.5 shall be as decided in writing by NDC and the C-4 Stockholder Representative; provided, that if NDC and the Stockholder Representative are not able to agree on the Disputed Indemnification Escrow Amount by such Distribution Date, the Disputed Indemnification Escrow Amount shall be the amount claimed by NDC in its notice of Indemnification Claim. Upon determination of the Disputed Indemnification Escrow Amount in accordance with the preceding sentence, the Escrow Agent shall promptly deliver to the Stockholders a distribution of cash, if any, in immediately available funds, and shares of NDC Common Stock from the Indemnification Escrow Amount, equal to the difference between the Aggregate Value as of the Distribution Date of the Indemnification Escrow Amount and the Disputed Indemnification Escrow Amount (the "Undisputed Indemnification Escrow Amount"), and such amount shall be paid to the respective Stockholders in accordance with their respective Percentage Interests. Any delivery of NDC Common Stock to Stockholders shall be of full shares and any fractional portions shall be rounded to a whole number by the Escrow Agent so that the number of shares remaining in escrow to be delivered will be fully allocated among such Stockholders. Upon the final resolution as agreed by NDC and the Stockholder Representative in writing of the amount of the Losses under Indemnification Claims pending as of the Distribution Date with respect to the Indemnification Escrow Amount (the "Final Indemnification Claim") for which a Disputed Indemnification Escrow Amount was retained in escrow, the Escrow Agent shall promptly distribute to NDC an amount in cash, if any, in immediately available funds, and shares of NDC Common Stock from the Indemnification Escrow Amount with an Aggregate Value as of the date of final resolution equal to the Final Indemnification Claim and shall deliver any remaining Disputed Indemnification Escrow Amount to the Stockholders in accordance with their respective Percentage Interests. 3.6 Effect of Final Delivery. This Agreement shall continue in full force and effect until the Escrow Agent has distributed all of the Escrow Amount pursuant to the terms hereof.

In the event of any disagreement or the presentation of adverse claims or demands in connection with or for any item affected hereby, the Escrow Agent shall, at its option, be entitled to refuse to comply with any such claims or demands during the continuance of such disagreement and may refrain from delivering any item affected hereby, and in so doing the Escrow Agent shall not become liable to the parties, or to any other person, due to its failure to comply with any such adverse claim or demand. The Escrow Agent shall be entitled to continue, without liability, to refrain and refuse to act until all of the rights of the adverse claimants have been either fully resolved among themselves, arbitrated to a final award, or finally adjudicated by a court having jurisdiction over the dispute. The Escrow Agent shall be held harmless and indemnified by the parties hereto in connection with any claims against it in connection with its service as escrow agent hereunder. Any action requested to be taken by the Escrow Agent hereunder and not otherwise specifically set forth herein shall require the agreement in writing of the Stockholder Representative, NDC and any successor Escrow Agent. 6.3 Successor.

The Escrow Agent and any successor Escrow Agent shall not be liable for any action taken in good faith in accordance with the advice of an attorney.

D-7 SOURCE INFORMATICS INC.'S UNITED STATES OPERATIONS NOTES TO FINANCIAL STATEMENTS JUNE 30, 1997 (AUDITED), 1996 (UNAUDITED), AND 1995 (UNAUDITED) 1. ORGANIZATION AND NATURE OF BUSINESS Walsh International Inc. ("Walsh") acquired a division of PCS Inc. in February 1990 that provided a range of data services, primarily based on a proprietary database of prescriptions dispensed, which are used by pharmaceutical companies in sales force compensation, territory realignment and focused promotion. On April 16, 1996, Walsh formed Source Informatics Inc. ("Source"), a Delaware corporation, for the purpose of creating the holding company for the entities engaged in such businesses (the "Source Business"). Effective as of that same date, Walsh transferred all of the assets and liabilities of the Source Business, together with cash, marketable securities, convertible preferred stock obligations, and other corporate assets to Source. In conjunction with the transfer of such assets and liabilities, all of the issued and outstanding capital stock of Source was spun off to the then current stockholders of Walsh. The financial statements and related footnotes contained herein reflect the operations of Source's United States Operations ("Source U.S."). As discussed in Note 9, Source entered into a stock purchase agreement with National Data Corporation ("NDC") in August 1997 to sell the stock of Source to NDC. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Presentation The financial statements of Source U.S. have been derived from the consolidated financial statements of Source and have been prepared to present its financial position, results of operations, and cash flows on a standalone basis. Accordingly, the accompanying financial statements include certain costs and expenses that have been allocated on a pro rata basis, primarily on distribution of management's time. In management's opinion, this allocation reflects the best estimate of the costs and expenses incurred by Source U.S. Such allocated expenses may not be indicative of what such expenses would have been had the United States operations been operated as a separate entity. The balance sheet as of June 30, 1996 and the related statements of operations, accumulated deficit, and cash flows for the two years ended June 30, 1996 are unaudited and, in the opinion of management, contain all adjustments (consisting of only normal recurring items) necessary for the fair presentation of the financial position and results of operations for such periods. Use Of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash And Cash Equivalents Source U.S. considers all highly liquid investments with maturity dates of three months or less from the date of acquisition by Source U.S. to be cash equivalents. Investments Source U.S. holds an investment in a one-year Treasury bill that is classified as a held-to-maturity security. The amount is restricted as the investment secures certain assets under capital lease. D-8 SOURCE INFORMATICS INC.'S UNITED STATES OPERATIONS NOTES TO FINANCIAL STATEMENTS--(CONTINUED) Revenue Recognition Revenue is recognized on the delivery of a product or as the service is rendered. Prebillings for products that have not yet been delivered or for services not yet rendered are classified as unearned revenue until the earnings process is complete. Credit Risk Financial instruments which potentially subject Source U.S. to concentrations of credit risk consist principally of cash balances and trade receivables. Source U.S. invests its excess cash with major banks. Source U.S.'s customer base principally comprises companies within the pharmaceutical industry. Source U.S. maintains reserves for potential credit losses, and such losses have been within management's expectations, given the generally strong credit ratings of the customers. Source U.S. does not require collateral from its customers. Property And Equipment Property and equipment are recorded at cost. All maintenance and repairs are expensed as incurred. Depreciation is provided using the straight-line method. Furniture, office equipment, and computer equipment are depreciated over five years. Leasehold improvements are amortized over the estimated lives of the assets or the lease terms, whichever are shorter. Upon disposal, cost and accumulated depreciation are removed from the accounts and gains (losses) are recognized in the statement of operations. Databases and Software Costs Costs associated with maintenance and updating of databases and all costs associated with internally developed software are expensed as incurred. Deferred Data Costs Deferred data costs consist of costs incurred by Source U.S. to obtain prescription data information used in Source U.S.'s products. Source U.S. purchases data monthly and delivers products based on this information in the following month. In order to match the cost of these products with the associated revenue, Source U.S. defers approximately one month's cost of prescription data. Income Taxes The income tax returns of Source include the operations of the United States business. For purposes of these financial statements, income taxes related to Source U.S. have been computed and recorded on a separate return basis based on the statutory rates in effect. Deferred income taxes are recorded using enacted tax laws and rates for the years in which the taxes are expected to be paid. Deferred income taxes are provided for items when there is a temporary difference in recording such items for financial reporting and income tax reporting. Long-Lived Assets Source U.S. periodically reviews the values assigned to long-lived assets such as property and equipment to determine whether any impairments are other than temporary. Management believes that the long-lived assets in the accompanying balance sheets are appropriately valued. D-9 SOURCE INFORMATICS INC.'S UNITED STATES OPERATIONS NOTES TO FINANCIAL STATEMENTS--(CONTINUED) Due to Parent Company "Due to parent company" represents the amount of net funds advanced to Source U.S. by Source. Advertising Source U.S. expenses all advertising costs as they are incurred. Concentration of Revenues Source U.S. derived approximately 49%, 47%, and 41% of its revenues from three customers in 1997, 1996, and 1995, respectively. 3. RELATED PARTY TRANSACTIONS Transactions With PMSI Source U.S. has a licensing agreement with Pharmaceutical Marketing Services, Inc. ("PMSI"), a company that shares certain management with Source, to market certain services. Additionally, Source U.S. provides certain services to PMSI and its subsidiaries. The principal agreements and terms are as follows: Alpha Database (Prescription) License Agreement The Alpha Database License Agreement, as amended and restated July 1, 1994, grants PMSI the sharing of revenue and expenses for a period of three years through June 30, 1997. Thereafter, the agreement will be automatically renewed for three additional five-year periods unless PMSI or Source U.S., for cause, terminates the agreement. The database license fee amounts received by Source U.S. were approximately $3,126,000, $3,094,000, and $2,663,000 for the years ended June 30, 1997, 1996, and 1995, respectively. Revenues earned under these agreements are allocated to both parties based upon historical percentages of revenue derived from Alpha Database. Data Processing Agreement Source provides specific data processing services to PMSI. Costs charged to PMSI totaled approximately $711,000, $1,191,000, and $1,883,000 for the years ended June 30, 1997, 1996, and 1995, respectively. Facilities Agreement PMSI sublets space from Source U.S. The revenue from PMSI under this sublet agreement was approximately $367,000, $492,000, and $259,000 for AND the years ended June 30, 1997, 1996, and 1995, respectively. Management Executive Services Agreement Source U.S. provides administrative, management, and executive services to PMSI. The costs charged by Source U.S. for these services are treated as a reduction of the related expenses. The amounts charged under this agreement were $1,384,000, $2,240,000, and $1,299,000 for the years ended June 30, 1997, 1996, and 1995. At June 30, 1997 and 1996, Source U.S. had a net current payable to PMSI of $1,208,000 and $377,000 respectively. Prior to the closing of the Acquisition (Note 9), all intercompany balances between PMSI and Source U.S. are expected to be paid in full. D-10 SOURCE INFORMATICS INC.'S UNITED STATES OPERATIONS NOTES TO FINANCIAL STATEMENTS--(CONTINUED) OTHER RELATED-PARTY TRANSACTIONS Transactions With Source Europe Source operates certain businesses in Europe to which the U.S. operations of Source provide certain services such as data processing, human resources, facilities, and finance. At June 30, 1997 and 1996, Source U.S. has a receivable from the Source Europe business of $11,299,000 and $3,566,000, respectively, included net within due from parent in the accompanying balance sheets.

The pro forma condensed consolidated financial information represents the historical operations of NDC, Source and PMSI Database adjusted for the effects of the Stock Purchase and the Merger as well as the effects of the acquisition of Health EDI completed in October 1997. This information has also been adjusted to conform to the presentation format and accounting policies of NDC. For comparability purposes, Source and PMSI Database's twelve months ended June 30, 1997 and three months ended September 30, 1997 are used in conjunction with the NDC twelve months ended May 31, 1997 and three months ended August 31, 1997. The pro forma financial information is provided for informational purposes only and is not necessarily indicative of actual results that would have been achieved had the Merger and the Stock Purchase been consummated at the beginning of the period presented or of future results. Historically, the financial results of Source US (the principal business of Source and PMSI Database, operated as a joint venture) have varied from quarter to quarter. These fluctuations are principally due to the timing of customer commitments to new products and services and the timing of delivery of Source US services. For example, many of the pharmaceutical manufacturing customers of Source US report results on a calendar year basis. Commitments are made by Source US's customers in the summer and fall for delivery in the first part of the next calendar year. Source US's fiscal year begins July 1. Source typically incurs expenses during the first half of its fiscal year (the last half of the calendar year) in preparation for roll-out of the products and services to meet customer requirements. Consequently, during Source US's first quarter, significant expense is incurred to generate revenues which should be recognized in future quarters. Unaudited pro forma financial information should be reviewed in conjunction with "Source Informatics Inc.--Management's Discussion and Analysis of Financial Condition and Results of Operations" located on pages 49 through 51 of this document.

(b) Reflects borrowings on NDC's line of credit to fund the cash portion of the purchase price ($38.25 million) and the payment of estimated acquisition costs of $4 million less the portion paid out of operating cash of $13.2 million.

(d) Reflects the excess of the purchase price over the net assets (liabilities) acquired in the acquisitions, net of a projected non- recurring charge based on preliminary results of a valuation study of approximately $67 million ($60.6 million after-tax) related to purchased in-process research and development. This charge relates entirely to the operations of Source U.S. Based on the allocation model of Source U.S. operations (76% to Source and 24% to PMSI), approximately $51 million of the charge can be attributable to Source and $16 million to PMSI. The purchase price equals $92 million and $48 million for Source and PMSI Database, respectively, based on 1,555,556 shares for Source and 1,059,829 shares for PMSI Database at $37.40 per share stock price plus $31.8 million and $6.5 million of cash for Source and PMSI Database, respectively, and $4 million in acquisition related expenses. Approximately $5.5 million in net liabilities are assumed to be acquired in the purchase of Source. Approximately $4.7 million of assets are assumed to be acquired in the purchase of PMSI Database. The intangibles and the related lives based on the preliminary results of the valuation study are as follows: Product technology................................. $17.3 million 5 years Assembled work force............................... 3.0 7 Customer relations/Goodwill........................ 53.5 20 The respective breakdown of the above identified components of the intangible asset can be attributed 76% to Source and 24% to PMSI based upon the aforementioned allocation model.

E-5 PART II INFORMATION NOT REQUIRED IN PROXY STATEMENT/PROSPECTUS ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS The Registrant's Bylaws provide for indemnification of directors and officers of the Registrant to the full extent permitted by Delaware law. Section 145 of the General Corporation Law of the State of Delaware provides generally that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at its request in such capacity in another corporation or business association, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. In addition, pursuant to the authority of Delaware law, the Certificate of Incorporation of the Registrant also eliminates the monetary liability of directors to the fullest extent permitted by Delaware law. Although the Certificate of Incorporation of the Registrant does not specifically address indemnification of directors for liabilities arising under federal securities laws, indemnification and any limitations or indemnification for such liabilities would be determined based upon the authority of Delaware law. Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the "Act") may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable.

ITEM 22. UNDERTAKINGS (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post- effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission II-2 pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;" provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at the time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form. (5) The registrant undertakes that every prospectus: (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post- effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the Registrant's Certificate of Incorporation or Bylaws, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefor, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment for the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. II-3 (d) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the Proxy Statement/Prospectus pursuant to Items 4, 10(b), 11, or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request. (e) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective. II-4 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant has duly caused this Amendment No. 2 to Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Atlanta, State of Georgia, on November 10, 1997.
