Notes to Condensed Consolidated Financial Statements
March 31, 2003
(Unaudited)

Note 1—Basis of Presentation

        The accompanying unaudited, condensed consolidated financial statements have been prepared pursuant to rules and regulations of the Securities and Exchange Commission and, therefore, do not include all information and footnote disclosures normally included in audited financial statements. However, in the opinion of management, all adjustments necessary to present fairly the results of operations, financial position and cash flows have been made. It is suggested that these statements be read in conjunction with the financial statements included in Abbott's Annual Report on Form 10-K for the year ended December 31, 2002.

Note 2—Supplemental Financial Information
(dollars in thousands)

			Three Months Ended March 31
			2003			2002
Net interest expense:
	Interest expense		$	48,181		$	62,941
	Interest income			(10,891	)		(10,055	)
Total			$	37,290		$	52,886

Note 3—Taxes on Earnings

        Taxes on earnings reflect the estimated annual effective rates. The effective tax rates are less than the statutory U.S. Federal income tax rate principally due to the benefit of tax exemptions in several taxing jurisdictions and the domestic dividend exclusion.

Note 4—Litigation and Environmental Matters

        Abbott is involved in various claims and legal proceedings including a number of antitrust suits and investigations in connection with the pricing of prescription pharmaceuticals. These suits and investigations allege that various pharmaceutical manufacturers have conspired to fix prices for prescription pharmaceuticals and/or to discriminate in pricing to retail pharmacies by providing discounts to mail-order pharmacies, institutional pharmacies and HMOs in violation of state and federal antitrust laws. The suits have been brought on behalf of individuals and retail pharmacies and name both Abbott and certain other pharmaceutical manufacturers and pharmaceutical wholesalers as defendants. The cases seek treble damages, civil penalties, and injunctive and other relief. Abbott has filed a response to each of the complaints denying all substantive allegations.

        There are several lawsuits pending in connection with the sales of Hytrin. These suits allege that Abbott violated state or federal antitrust laws and, in some cases, unfair competition laws by signing patent settlement agreements with Geneva Pharmaceuticals, Inc. and Zenith Laboratories, Inc. Those agreements related to pending patent infringement lawsuits between Abbott and the two companies. Some of the suits also allege that Abbott violated various state or federal laws by filing frivolous patent infringement lawsuits to protect Hytrin from generic competition. The cases seek treble damages, civil

penalties and other relief. Abbott has filed or intends to file a response to each of the complaints denying all substantive allegations.

        The U.S. Attorney's office in the Southern District of Illinois is conducting an industry-wide investigation of the enteral nutritional business, including Abbott's Ross division. Abbott is cooperating with the investigation and is responding to subpoenas that have been issued. The investigation is both civil and criminal in nature. While it is not feasible to predict the outcome of this investigation with certainty, an adverse outcome in this investigation could have a material adverse effect on Abbott's cash flows and results of operations in a given year, but should not have a material adverse effect on Abbott's financial position.

        Abbott has been identified as a potentially responsible party for investigation and cleanup costs at a number of locations in the United States and Puerto Rico under federal and state remediation laws and is investigating potential contamination at a number of company-owned locations. Abbott has recorded an estimated cleanup cost for each site for which management believes Abbott has a probable loss exposure. No individual site cleanup exposure is expected to exceed $3 million, and the aggregate cleanup exposure is not expected to exceed $20 million.

        Within the next year, legal proceedings may occur that may result in a change in the estimated reserves recorded by Abbott. Abbott is unable to estimate the reasonably probable range of loss for the claims and investigations discussed above and in Note 5. Except for the enteral nutritional investigation, Abbott has recorded reserves of approximately $150 million for its legal proceedings and environmental exposure including those discussed above and in Note 5. These reserves represent management's best estimate of probable loss, as defined by Statement of Financial Accounting Standards No. 5, "Accounting for Contingencies." While it is not feasible to predict the outcome of such proceedings with certainty, management believes that their ultimate disposition should not result in a loss materially different than the amount recorded, and should not have a material adverse effect on Abbott's financial position, cash flows, or results of operations, except as noted above with respect to the enteral nutritional investigation.

Note 5—TAP Pharmaceutical Products Inc.

        TAP and Abbott have been named as defendants in several lawsuits alleging violations of various state or federal laws in connection with TAP's marketing and pricing of Lupron. Abbott has filed or intends to file a response to each of the lawsuits denying all substantive allegations.

        Within the next year, legal proceedings may occur that may result in a change in the estimated reserves recorded by TAP and Abbott. While it is not feasible to predict the outcome of such pending claims, proceedings, and investigations with certainty, management is of the opinion that their ultimate disposition should not have a material adverse effect on Abbott's financial position, cash flows, or results of operations.

Note 6—U.S. Food and Drug Administration Consent Decree

        In November 1999, Abbott reached agreement with the U.S. government to have a consent decree entered to settle issues involving Abbott's diagnostics manufacturing operations in Lake County, Ill. The decree, which was amended in December 2000, requires Abbott to ensure its diagnostics manufacturing processes in Lake County conform with the U.S. Food and Drug Administration's (FDA) Quality System Regulation (QSR). The decree allows for the continued manufacture and distribution of medically necessary diagnostic products made in Lake County. However, Abbott is prohibited from manufacturing or distributing certain diagnostic products until Abbott ensures the processes in its Lake County diagnostics manufacturing operations conform with the QSR. The decree allows Abbott to export diagnostic products and components for sale and distribution outside the United States if they meet the export requirements of the Federal Food, Drug and Cosmetic Act.

6

---

Under the terms of the amended consent decree, Abbott was to ensure its diagnostics manufacturing operations are in conformance with the QSR by January 15, 2001. The FDA performed an inspection of Abbott's Lake County, Ill. diagnostics manufacturing operations during the fourth quarter of 2001 and first quarter of 2002 to determine whether those operations are in conformity with the QSR. In May 2002, these operations were found not to be in conformity. Accordingly, Abbott was required to make additional payments to the government and continue its efforts to achieve full compliance. A pretax charge of $129 million related to this matter was recorded in the second quarter of 2002. The FDA will determine Abbott's conformance with the QSR after a re-inspection of Abbott's facilities. If the FDA concludes that the operations are not in conformance with the QSR, Abbott may continue to be subject to additional costs and loss of revenue.

Note 8—Segment Information (dollars in millions)

        Revenue Segments—Abbott's principal business is the discovery, development, manufacture and sale of a broad line of health care products. Abbott's products are generally sold directly to retailers, wholesalers, hospitals, health care facilities, laboratories, physicians' offices and government agencies throughout the world. Abbott's reportable segments are as follows:

        Pharmaceutical Products—U.S. sales of a broad line of pharmaceuticals.

        Diagnostic Products—Worldwide sales of diagnostic systems and tests for blood banks, hospitals, consumers, commercial laboratories and alternate-care testing sites.

        Hospital Products—U.S. sales of intravenous and irrigation fluids and related administration equipment, drugs and drug-delivery systems, anesthetics, critical care products, and other medical specialty products for hospitals and alternate-care sites.

        Ross Products—U.S. sales of a broad line of adult and pediatric nutritional products, pediatric pharmaceuticals and consumer products.

7

---

        International—Non-U.S. sales of all of Abbott's pharmaceutical, hospital and nutritional products. Products sold by International are manufactured by domestic segments and by international manufacturing locations.

        Abbott's underlying accounting records are maintained on a legal entity basis for government and public reporting requirements. Segment disclosures are on a performance basis consistent with internal management reporting. Intersegment transfers of inventory are recorded at standard cost and are not a measure of segment operating earnings. The cost of some corporate functions and the cost of certain employee benefits are sold to reportable segments at predetermined rates that approximate cost. Remaining costs, if any, are not allocated to reportable segments. Intangible assets and related amortization from business acquisitions are not allocated to segments. The following segment information has been prepared in accordance with the internal accounting policies of Abbott, as described above, and are not presented in accordance with generally accepted accounting principles applied to the consolidated financial statements.

        In 2001 and 2002, Abbott implemented restructuring plans related primarily to the operations of the acquired pharmaceutical business of BASF. The following summarizes the restructuring activity:

Note 10—Sale of Product Rights

        In the first quarter 2003, Abbott completed the sale of its U.S. eye and ear care product lines and in the first quarter 2002, Abbott sold its U.S. Selsun Blue product rights and recorded these transactions in net sales in accordance with Abbott's revenue recognition accounting policies as discussed in Note 1 to the financial statements included on Abbott's Annual Report in Form 10-K.

Note 11—Incentive Stock Programs

        Abbott measures compensation cost using the intrinsic value-based method of accounting for stock options and replacement stock options granted to employees. Had compensation cost been determined using the fair market value-based accounting method, pro forma net income (in millions) and earnings per share (EPS) amounts would have been as follows:

Percentage changes are based on unrounded numbers.

        Worldwide sales for the first quarter 2003 reflect unit growth and the positive effect of the relatively weaker U.S. dollar. Excluding the effect of the relatively weaker U.S. dollar, consolidated sales increased 6.3 percent and international sales increased 4.6 percent over the first quarter 2002. In addition, excluding the effect of the relatively weaker U.S. dollar, international Anti-Infectives product sales decreased 4.4 percent. The acquisition of the pharmaceutical business of BASF in 2001 favorably impacted the Diabetes/Metabolism product sales of the Pharmaceutical Products segment and the Other Pharmaceuticals product sales of the International segment for 2002. Increased sales of TriCor favorably impacted the Cardiology product sales of the Pharmaceutical Products segment for both 2003 and 2002, and Neuroscience product sales for 2003 were unfavorably impacted by wholesaler buying patterns for Depakote. Increased sales of Ultane favorably impacted the Anesthesia product sales of the Hospital Products segment in 2003. On December 31, 2002, the FDA approved Humira for the treatment of rheumatoid arthritis. U.S. sales of Humira in the first quarter 2003 were $24 million and international sales of Humira from sales through patient named basis programs were $2 million in the first quarter 2003. Worldwide sales of Humira in 2003 are forecasted to be more than $200 million based on the U.S. launch and an expected European launch later in 2003.

        Gross profit margin (sales less cost of products sold, including freight and distribution expenses) was 52.0 percent for the first quarter 2003, compared to 54.7 percent for the first quarter 2002. This decrease was due primarily to unfavorable product mix, unfavorable exchange and higher manufacturing costs.

        Research and development expenses for the first quarter 2003 increased 13.8 percent over the comparable 2002 period due, in part, to increased spending to support pipeline programs, such as the follow-on indications for Humira. The majority of research and development expenditures continues to be concentrated on pharmaceutical and diagnostic products.

        Selling, general and administrative expenses for the first quarter 2003 increased 11.7 percent over the comparable 2002 period. The increase is due primarily to increased selling and marketing support for new and existing products, including accelerated spending for the launch of Humira, due to its earlier-than-expected FDA approval, as well as spending on other marketed pharmaceutical products.

        In November 1999, Abbott reached agreement with the U.S. government to have a consent decree entered to settle issues involving Abbott's diagnostics manufacturing operations in Lake County, Ill. The decree, which was amended in December 2000, requires Abbott to ensure its diagnostics manufacturing processes in Lake County conform with the U.S. Food and Drug Administration's (FDA) Quality System Regulation (QSR). The decree allows for the continued manufacture and distribution of medically necessary diagnostic products made in Lake County. However, Abbott is prohibited from manufacturing or distributing certain diagnostic products until Abbott ensures the processes in its Lake County diagnostics manufacturing operations conform with the QSR. The decree allows Abbott to export diagnostic products and components for sale and distribution outside the United States if they meet the export requirements of the Federal Food, Drug and Cosmetic Act. Under the terms of the amended consent decree, Abbott was to ensure its diagnostics manufacturing operations are in conformance with the QSR by January 15, 2001. The FDA performed an inspection of Abbott's Lake County, Ill. diagnostics manufacturing operations during the fourth quarter of 2001 and first quarter of 2002 to determine whether those operations are in conformity with the QSR. In May 2002, these operations were found not to be in conformity. Accordingly, Abbott was required to make additional payments to the government and continue its efforts to achieve full compliance. A pretax charge of $129 million related to this matter was recorded in the second quarter of 2002. The FDA will determine Abbott's conformance with the QSR after a re-inspection of Abbott's facilities. If the FDA concludes that the operations are not in conformance with the QSR, Abbott may continue to be subject to additional costs and loss of revenue. The consent decree affects the sales and margin of the Immunochemistry products of the Diagnostic Products segment.

        The U.S. Attorney's office in the Southern District of Illinois is conducting an industry-wide investigation of the enteral nutritional business, including Abbott's Ross division. Abbott is cooperating with the investigation and is responding to the subpoenas that have been issued. The investigation is both civil and criminal in nature. While it is not feasible to predict the outcome of this investigation with certainty, an adverse outcome in this investigation could have a material adverse effect on Abbott's cash flows and results of operations for a given year, but should not have a material adverse effect on Abbott's financial position.

Restructuring Charges
(dollars in millions)

        In October 2002, Abbott announced restructuring plans to align Abbott's global manufacturing operations with its scientific focus and to achieve greater operating efficiencies in its Diagnostics and International segments. The following summarizes the restructuring activity:

        In 2001 and 2002, Abbott implemented restructuring plans related primarily to the operations of the acquired pharmaceutical business of BASF. The following summarizes the restructuring activity:

Net Interest Expense

        Net interest expense decreased in the first quarter of 2003 due primarily to lower interest rates and a lower level of debt.

Sale of Product Rights

        In the first quarter 2003, Abbott completed the sale of its U.S. eye and ear care product lines and in the first quarter 2002, Abbott sold its U.S. Selsun Blue product rights and recorded these transactions in net sales in accordance with Abbott's revenue recognition accounting policies as discussed in Note 1 to the financial statements included in Abbott's Annual Report on Form 10-K. Related gains recorded in net sales were not significant to consolidated net sales.

Taxes on Earnings

        Taxes on earnings reflect the estimated annual effective rates. The effective tax rates are less than the statutory U.S. Federal income tax rate principally due to the benefit of tax exemptions in several taxing jurisdictions and the domestic dividend exclusion.

Liquidity and Capital Resources at March 31, 2003 Compared with December 31, 2002

        Net cash from operating activities for the first quarter 2003 totaled $943 million. Abbott expects annual cash flow from operating activities to continue to exceed Abbott's capital expenditures and cash dividends.

        At March 31, 2003, Abbott had working capital of approximately $2.5 billion compared to working capital of approximately $2.1 billion at December 31, 2002. The increase in working capital in 2003 was primarily due to operating cash flows used to increase cash and cash equivalents.

        At March 31, 2003, Abbott's bond ratings were AA by Standard & Poor's Corporation and Aa3 by Moody's Investors Service. Abbott has readily available financial resources, including unused lines of credit of $3.0 billion, which support commercial paper borrowing arrangements.

        In June 2000, the Board of Directors authorized the purchase of 25 million shares of Abbott's common stock and Abbott purchased 10.6 million shares from this authorization in 2001 and 2000. Common stock purchases were temporarily suspended in January 2001, following Abbott's announced acquisition of the pharmaceutical business of BASF. In 2003, Abbott announced that it plans to purchase the remaining 14.4 million shares from time to time on the open market. During the first quarter 2003, Abbott purchased 2.7 million of its common shares at a cost of $98 million. As of March 31, 2003, an additional 11.7 million shares may be purchased in future periods under the June 2000 authorization by the Board of Directors.

        In the first quarter 2003, $200 million was funded to Abbott's main domestic pension plan.

        In 2003, Abbott established a yen denominated line of credit of approximately $1 billion. Borrowings outstanding at March 31, 2003 were approximately $1 billion. Proceeds from this line of credit were used to pay off an existing yen denominated credit facility of approximately $280 million and to pay down domestic commercial paper borrowings. The new line of credit expires in August 2003, and Abbott plans to replace this facility with long-term yen denominated debt.

        In 2003, Abbott entered into interest rate hedge contracts totaling $800 million to manage its exposure to changes in the fair value of $800 million of fixed-rate debt due in July 2006. These contracts are designated as fair value hedges of the variability of the fair value of fixed-rate debt due to changes in the long-term bench-mark interest rates. The effect of the hedge is to change a fixed-rate interest obligation to a variable rate for that portion of the debt. Under a registration statement filed with the Securities and Exchange Commission in February 2001, Abbott may issue up to $250 million of securities in the future in the form of debt securities or common shares without par value.

Legislative Issues

        Abbott's primary markets are highly competitive and subject to comprehensive government regulation. Abbott expects debate to continue at both the federal and the state levels over the availability, method of delivery, and payment for health care products and services. Abbott believes that if legislation is enacted, it could have the effect of reducing prices, or reducing the rate of price increases for medical products and services. International operations are also subject to a significant degree of government regulation. It is not possible to predict the extent to which Abbott or the health care industry in general might be adversely affected by these factors in the future. A more complete

14

---

discussion of these factors is contained in Item 1, Business, in the Annual Report on Form 10-K, which is available upon request.

Private Securities Litigation Reform Act of 1995—A Caution Concerning Forward-Looking Statements

        Under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, Abbott cautions investors that any forward-looking statements or projections made by Abbott, including those made in this document, are subject to risks and uncertainties that may cause actual results to differ materially from those projected. Economic, competitive, governmental, technological and other factors that may affect Abbott's operations are discussed in Exhibit 99.1 to the Annual Report on Form 10-K.

Item 4.    Controls and Procedures.

(a)

Evaluation of disclosure controls and procedures. The Chief Executive Officer, Miles D. White, and Chief Financial Officer, Thomas C. Freyman, evaluated the effectiveness of Abbott Laboratories' disclosure controls and procedures as of a date within 90 days of the filing of this report (Evaluation Date), and concluded that, as of the Evaluation Date, Abbott Laboratories' disclosure controls and procedures were effective to ensure that information Abbott is required to disclose in its filings with the Securities and Exchange Commission under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms, and to ensure that information required to be disclosed by Abbott in the reports that it files under the Exchange Act is accumulated and communicated to Abbott's management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.



(b)

Changes in internal controls. There were no significant changes to Abbott's internal controls or in other factors that could significantly affect these controls subsequent to the Evaluation Date.

PART II.    OTHER INFORMATION

Item 1.    Legal Proceedings

        Abbott is involved in various claims, legal proceedings and investigations, including (as of March 31, 2003) those described below.

        In its 2002 Form 10-K, Abbott reported that the United States District Court for the Northern District of Illinois had dismissed the shareholder derivative actions filed in 1999 against Abbott's then current directors and certain former directors in connection with Abbott's consent decree with the FDA regarding Abbott's diagnostic manufacturing operations in Lake County, Illinois. The actions had been consolidated as In re Abbott Laboratories Derivative Shareholder Litigation. The plaintiffs alleged the directors breached their duty of care by failing to prevent Abbott's alleged regulatory noncompliance and sought unspecified damages from the directors. Plaintiffs appealed to the United States Court of Appeals for the Seventh Circuit. In March 2003, the Seventh Circuit reversed the District Court's dismissal.

        In its 2002 Form 10-K, Abbott reported that three cases were pending in which Abbott sought to protect its patents for divalproex sodium (a drug that Abbott sells under the trademark Depakote®), including a case brought by Abbott against Alra Laboratories, Inc. ("Alra") and a case brought by Abbott against Andrx Corporation, Andrx Pharmaceuticals, Inc., and Andrx Pharmaceuticals, LLC (the "Andrx case"). As previously reported, the United States District Court for the Northern District of Illinois granted Abbott's motions for summary judgment against Alra, finding Alra's product infringed Abbott's patents. Alra appealed the decision to the Federal Circuit Court of Appeals. In March 2003, the Court of Appeals issued an order providing that the appeal would not be resolved on the merits and remanding the case to the lower court for a determination as to whether the lower court's judgment should stand or be vacated. As previously reported, the Andrx case had been stayed by the United States District Court for the Southern District of Florida at the request of the parties. In March 2003, Abbott moved to dismiss the action as moot.

        In its 2002 Form 10-K, Abbott reported that a number of antitrust cases are pending in federal court and various state courts in connection with the settlement of patent litigation by Abbott involving terazosin hydrochloride, a drug sold by Abbott under the trademark Hytrin®. These cases (which were brought against Abbott, Geneva Pharmaceuticals, Inc., and Zenith Goldline Pharmaceuticals, Inc.) seek actual damages, treble damages, and other relief and allege Abbott violated state and/or federal

16

---

antitrust laws and, in some cases, unfair competition laws. On January 8, 2003, one of the previously reported cases, Hopper, was remanded to the Superior Court of Pitt County, North Carolina.

        In its 2002 Form 10-K, Abbott reported that a number of cases, brought as purported class actions or representative actions on behalf of individuals or entities, are pending that allege generally that Abbott and numerous other pharmaceutical companies reported false pricing information in connection with certain drugs that are reimbursable under Medicare and Medicaid. Four cases have been brought by state Attorney Generals (California, Montana, Nevada and West Virginia). These cases generally seek damages, treble damages, disgorgement of profits, restitution and attorneys' fees. The federal court cases have been consolidated in the United States District Court in Massachusetts under the Multidistrict Litigation Rules as In re: Pharmaceutical Industry Average Wholesale Price Litigation, MDL 1456. The following four previously reported cases have now been transferred to MDL 1456: Rice, Thompson, Congress of California Seniors, and County of Suffolk, et al. As of March 31, 2003, transfers to MDL 1456 were pending for the following four previously reported cases, which have all been removed to federal court: Turner, Swanston, individually and on behalf of himself and all others similarly situated, Digel, and State of California ex rel. Ven-A-Care of the Florida Keys, Inc. Abbott has filed or intends to file a response in each case denying all substantive allegations.

        In its 2002 Form 10-K, Abbott reported that a number of cases have been brought against TAP Pharmaceutical Products Inc., Abbott and Takeda Chemical Industries, Ltd. in various courts that generally allege that TAP reported false pricing information in connection with Lupron®, a product reimbursable under Medicare. One of the previously reported cases Swanston, filed in March 2002 in Maricopa County, Arizona, was amended to include claims against numerous pharmaceutical companies. That case was removed to federal court and a transfer to In re: Pharmaceutical Industry Average Wholesale Price Litigation, MDL 1456, is pending.

        In its 2002 Form 10-K, Abbott reported that four cases were pending in which Abbott seeks to protect its patents for fenofibrate (a drug Abbott sells under the trademark TriCor®). Two of these cases, Novopharm Limited and IMPAX Laboratories, Inc., involve Abbott's capsule product. In Novopharm Limited, the United States Court of Appeals for the Federal Circuit affirmed the lower court's grant of summary judgment in favor of Novopharm. Abbott is seeking a rehearing before the Federal Circuit. In the second proceeding, IMPAX Laboratories, Inc., the United States District Court for the Northern District of Illinois granted summary judgment of non-infringement in favor of IMPAX. In addition to the previously reported cases, on February 24, 2003, Abbott filed a lawsuit against Par Pharmaceuticals, Inc., in the United States District Court for New Jersey alleging infringement of patents with respect to Abbott's tablet product.

        In its 2002 Form 10-K, Abbott reported that Abbott is a defendant in numerous lawsuits involving the drug oxycodone (a drug sold under the trademark OxyContin®), which is manufactured by Purdue Pharma. Abbott promotes OxyContin to certain specialty physicians, including surgeons and anesthesiologists under a co-promotion agreement with Purdue Pharma. Purdue Pharma is a defendant in each lawsuit and, pursuant to the co-promotion agreement, Purdue is required to indemnify Abbott in each lawsuit. Most of the lawsuits allege generally that plaintiffs suffered personal injuries as a result of taking OxyContin. Some of the lawsuits allege consumer protection violations and unfair trade practices. One suit by a third party payor alleges antitrust pricing violations and overpricing of the drug. As of March 31, 2003, there were a total of 238 lawsuits pending in which Abbott is a party. 101 cases were pending in federal court. 137 cases were pending in state court. 212 cases were brought by individual plaintiffs, and 25 cases were brought as purported class action lawsuits. One case has been brought by the Attorney General for the State of West Virginia.

        In its 2002 Form 10-K, Abbott reported that the U.S. Attorney's Office in the Southern District of Illinois is conducting an industry-wide investigation of the enteral nutritional business, including Abbott's Ross division. Abbott is cooperating with the investigation and is responding to subpoenas

17

which have been issued. The investigation is both civil and criminal in nature. While it is not feasible to predict the outcome of this investigation with certainty, an adverse outcome in this investigation could have a material adverse effect on Abbott's cash flows and results of operations in a given year, but should not have a material adverse effect on Abbott's financial position.

        While it is not feasible to predict the outcome of such pending claims, proceedings and investigations with certainty, management is of the opinion that their ultimate dispositions should not have a material adverse effect on Abbott's financial position, results of operation or cash flows, except as noted above with respect to the enteral nutritional investigation.

Item 4.    Submission of Matters to a Vote of Security Holders

        Abbott Laboratories held its Annual Meeting of Shareholders on April 25, 2003. The following is a summary of the matters voted on at that meeting.

        (a)   The shareholders elected Abbott's entire Board of Directors. The persons elected to Abbott's Board of Directors and the number of shares cast for and the number of shares withheld, with respect to each of these persons, were as follows:

        (b)   The shareholders ratified the appointment of Deloitte & Touche LLP as Abbott's auditors. The number of shares cast in favor of the ratification of Deloitte & Touche LLP, the number against, and the number abstaining were as follows:

        (c)   The shareholders rejected a shareholder proposal regarding executive compensation. The number of shares cast in favor of the shareholder proposal, the number against, the number abstaining, and the number of broker non-votes were as follows:
