Abbott Laboratories and Subsidiaries Notes to Condensed Consolidated Financial Statements March 31, 2000 (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 (which include only normal 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, 1999. Note 2 - Supplemental Financial Information (dollars in thousands) Three Months Ended March 31 ------------------------ 2000 1999 -------- -------- Net interest expense: Interest expense................... $ 32,215 $ 40,348 Interest income.................... (20,181) (14,496) -------- -------- Total................................. $ 12,034 $ 25,852 ======== ======== Note 3 - Taxes on Earnings Taxes on earnings reflect the estimated annual effective tax rates. The effective tax rates are less than the statutory U.S. Federal income tax rate principally due to the domestic dividend exclusion and tax incentive grants related to subsidiaries operating in Puerto Rico, the Dominican Republic, Ireland, and the Netherlands. Note 4 - Litigation and Environmental Matters Abbott is involved in various claims and legal proceedings including numerous 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 and at least one mail-order pharmacy company as defendants. The cases seek treble damages, civil penalties, and injunctive and other relief. Abbott has filed or intends to file a response to each of the remaining complaints denying all substantive allegations. In addition, there are several lawsuits and one investigation pending in connection with the sales of HYTRIN. These suits and the investigation allege that Abbott violated state or federal antitrust laws and, in some cases, unfair competition laws by signing separate 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. Abbott has also 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 expects that within the next year, legal proceedings will occur that may result in a change in the estimated reserves recorded by Abbott. While it is not feasible to predict the outcome of such pending claims, proceedings, investigations and remediation activities 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. 5

Notes to Condensed Consolidated Financial Statements March 31, 2000 (Unaudited), continued The matters above are discussed more fully in Note 14 to the financial statements included in Abbott's Annual Report on Form 10-K, which is available upon request. Note 5 - U.S. Food and Drug Administration Consent Decree In November 1999, Abbott reached agreement with the U.S. Food and Drug Administration to have a consent decree entered to settle issues involving Abbott's diagnostics manufacturing operations in Lake County, Ill. The decree requires Abbott to ensure its diagnostics manufacturing processes in Lake County, Ill., conform with the FDA's current Quality System Regulation. The decree allows for the continued manufacture and distribution of medically necessary diagnostic products made in Lake County, Ill. However, Abbott is prohibited from manufacturing or distributing certain diagnostic products until Abbott ensures the processes in its Lake County, Ill., diagnostics manufacturing operations conform with the current Quality System Regulation. Under the terms of the consent decree, among other actions, Abbott has submitted to the FDA a proposed master compliance and validation plan to ensure its processes conform with the current Quality System Regulation. The decree requires Abbott to ensure its facilities are in conformance with the current Quality System Regulation within one year from the date of the consent decree. The consent 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.

Notes to Condensed Consolidated Financial Statements March 31, 2000 (Unaudited), continued Note 7 - 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 and services. Abbott's products are generally sold directly to retailers, wholesalers, hospitals, health care facilities, laboratories, physicians' offices and government agencies throughout the world. Segments are identified as those revenue divisions that report directly to the chief operating officer of Abbott. 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 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. 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 segments at predetermined rates which approximate cost. Remaining costs, if any, are not allocated to revenue segments. The following segment information has been prepared in accordance with the internal accounting policies of Abbott, as described above, and may not be presented in accordance with generally accepted accounting principles.

Notes to Condensed Consolidated Financial Statements March 31, 2000 (Unaudited), continued Note 8 -- Sale of Agricultural Products Business On January 20, 2000, Abbott sold its agricultural products business to Sumitomo Chemical Co., Ltd., resulting in a $46 million gain recorded in the first quarter 2000. In addition, under the terms of the agreement, upon Sumitomo achieving a specified sales milestone, an additional $80 to $90 million would be due to Abbott. This could occur as early as the second quarter of 2000. Under the transaction, Sumitomo acquired research and development, sales, marketing, and support operations for Abbott's entire line of naturally occurring biopesticides, plant growth regulators and other products for agriculture, public health and forestry. Bulk active ingredient manufacturing rights were retained by Abbott. For the full year 1999, Abbott recorded approximately $102 million in sales from this business. 8

FINANCIAL REVIEW RESULTS OF OPERATIONS - FIRST QUARTER 2000 COMPARED WITH FIRST QUARTER 1999 The following table details sales by segment for the first quarter 2000: (dollars in millions) Net Sales to Percentage External Customers Change (a) ------------------- ----------- Three Months Ended March 31 --------------------------------------- 2000 1999 ------ ------ Pharmaceutical (b).............................. $ 607 $ 624 (2.7) Diagnostics..................................... 708 715 (1.1) Hospital (b).................................... 570 576 (1.1) Ross............................................ 550 501 9.7 International................................... 852 832 2.5 ------ ------ Total Reportable Segments....................... 3,287 3,248 1.2 Other........................................... 66 65 ------ ------ Net Sales....................................... $3,353 $3,313 1.2 ====== ====== Total U.S....................................... $2,061 $2,055 0.3 ====== ====== Total International............................. $1,292 $1,258 2.7 ====== ====== (a) Percentage changes are based on unrounded numbers. (b) In 2000, management of the cardiovascular medicine franchise was transferred from the Pharmaceutical segment to the Hospital segment. Net sales for 1999 have been restated to reflect this reclassification. Worldwide sales for the first quarter reflect primarily unit growth. Excluding the negative effect of the relatively stronger U.S. dollar, sales increased 2.8 percent over the first quarter 1999. Pharmaceutical segment sales decreased primarily due to volume shortfalls for HYTRIN. Diagnostics segment sales decreased primarily due to the effect of the consent decree as discussed in Note 5 and due to the negative effect of the relatively stronger U.S. Dollar. Excluding exchange, Diagnostics and International segment sales increased 1.9 and 6.3 percent, respectively. Diluted earnings per common share for the quarter rose to 44 cents, up 2.3 percent from 43 cents a year ago. Net earnings increased 3.6 percent to $693 million, from $669 million in the first quarter of 1999. In late 1998, the U.S. Food and Drug Administration (FDA) suspended its approval of the release of production lots of Abbott's pharmaceutical product ABBOKINASE due to Current Good Manufacturing Practice concerns raised by the FDA following inspections of Abbott and its raw material supplier. On December 10, 1999, Abbott met with the FDA to review Abbott's plan for the qualification of new raw materials and reinitiation of manufacturing. In the future, Abbott will sell only ABBOKINASE that is manufactured with new raw materials that meet the FDA's criteria. Abbott cannot predict, however, whether it will be successful in qualifying new raw material sources or the effect of this matter on future sales of ABBOKINASE. It is anticipated, however, that sales of ABBOKINASE will resume after 2000. In 1999, sales of ABBOKINASE were approximately $47 million, all of which were recorded in the first quarter. In August 1999, Geneva Pharmaceuticals, Inc. began shipments of generic HYTRIN in the United States, which has adversely impacted Abbott's HYTRIN sales. Full year U.S sales of HYTRIN amounted to $466 million in 1999. For the first quarter 2000, U.S. Sales of HYTRIN were $34 million. As a result of the consent decree entered into with the U.S. Food and Drug Administration in 1999, as discussed in Note 5, Abbott is prohibited from manufacturing or distributing certain diagnostic products until Abbott ensures the processes in its Lake County, Ill., diagnostics manufacturing operations conform with the current Quality System Regulation. The consent decree resulted in a one-time charge of $168 million in 1999. In addition, Abbott estimates that 2000 sales may be negatively impacted up to $250 million and earnings per share may be negatively impacted up to 10 cents per share. Gross profit margin (sales less cost of products sold, including freight and distribution expenses) was 55.4 percent for the 2000 first quarter, compared to 56.1 percent for the 1999 first quarter. This decrease was primarily due to unfavorable product mix, primarily lower sales of pharmaceuticals. 9

FINANCIAL REVIEW (continued) Research and development expenses for the first quarter 2000 increased 19.2 percent over the comparable 1999 period and includes charges relating to several research and development collaboration agreements entered into in the first quarter 2000. 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 2000 increased 6.5 percent over the comparable 1999 period, due primarily to increased selling and marketing support for new and existing products. SALE OF AGRICULTURAL PRODUCTS BUSINESS On January 20, 2000, Abbott sold its agricultural products business to Sumitomo Chemical Co., Ltd., resulting in a $46 million gain recorded in the first quarter 2000. In addition, under the terms of the agreement, upon Sumitomo achieving a specified sales milestone, an additional $80 to $90 million would be due to Abbott. This could occur as early as the second quarter of 2000. Under the transaction, Sumitomo acquired research and development, sales, marketing, and support operations for Abbott's entire line of naturally occurring biopesticides, plant growth regulators and other products for agriculture, public health and forestry. Bulk active ingredient manufacturing rights were retained by Abbott. For the full year 1999, Abbott recorded approximately $102 million in sales from this business. INTEREST (INCOME) EXPENSE, NET Net interest expense decreased in 2000 due primarily to a lower level of borrowings as a result of the termination of the common share purchase program. TAXES ON EARNINGS The effective income tax rate was 27.0 percent in 2000 and 28.0 percent in 1999. The tax rate for 2000 was reduced primarily due to the domestic dividend exclusion. LIQUIDITY AND CAPITAL RESOURCES AT MARCH 31, 2000 COMPARED WITH DECEMBER 31, 1999 Net cash from operating activities for the first quarter 2000 totaled $380 million. Abbott expects annual cash flow from operating activities to continue to approximate or exceed Abbott's capital expenditures and cash dividends. Abbott has maintained its favorable bond ratings (AAA by Standard & Poor's Corporation and Aa1 by Moody's Investors Service) and continues to have readily available financial resources, including unused domestic lines of credit of $2.505 billion at March 31, 2000. These lines of credit support domestic commercial paper borrowing arrangements. Abbott may issue up to $521 million of securities in the future under a registration statement filed with the Securities and Exchange Commission in 1999. Of the $521 million, Abbott may issue up to $271 million either in the form of debt securities or common shares without par value. The remaining $250 million may only be issued in the form of debt securities. LEGISLATIVE ISSUES Abbott's primary markets are highly competitive and subject to substantial 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 discussion of these factors is contained in Item 1, Business, in the Annual Report on Form 10-K, which is available upon request. 10

FINANCIAL REVIEW (continued) RECENTLY ISSUED ACCOUNTING STANDARD In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement requires the recognition of the fair value of derivatives as either assets or liabilities. The statement is effective for fiscal years beginning after June 15, 2000. Adoption of the provisions of this statement will not have a material effect on the financial statements of Abbott. 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. 11

PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS Abbott is involved in various claims and legal proceedings, including those described below. In its 1999 Annual Report on Securities and Exchange Commission Form 10-K (the "1999 Form 10-K"), Abbott reported that two lawsuits were pending involving Abbott's patents for divalproex sodium. Three additional lawsuits have been filed. On March 9, 2000, after having been notified that Andrx Corporation had filed an abbreviated new drug application to market a generic divalproex sodium, Abbott filed a patent infringement lawsuit against Andrx Corporation, Andrx Pharmaceutical, and Andrx Pharmaceutical, L.L.C. in the United States District Court for the Northern District of Illinois. The defendants have filed a motion to dismiss this complaint. On April 14, 2000, Abbott filed patent infringement lawsuits against these three Andrx companies in the United States District Court for the Southern District of Florida and against Andrx L.L.C. in the United States District Court for the Eastern District of Virginia. As of April 14, 2000, 17 antitrust lawsuits and one antitrust investigation involving Abbott's patents for terazosin hydrochloride, a drug that Abbott sells under the trademark Hytrin-Registered Trademark-, were pending. The final patent infringement lawsuit involving Abbott's patents for terazosin hydrochloride was resolved during the first quarter of 2000. As previously reported, Abbott sued Mylan Pharmaceuticals, Inc. ("Mylan") alleging patent infringement. Mylan contended that Abbott's patent which covers their version of terazosin hydrochloride is invalid and unenforceable. On October 4, 1999, Mylan's motion in the appellate court for Summary Affirmance was granted. In February 2000, the United States Supreme Court denied Abbott's petition for a writ of certiorari. In its 1999 Form 10-K, Abbott reported that 13 lawsuits were pending relating to Abbott's agreements with Geneva Pharmaceuticals, Inc. ("Geneva") and Zenith Laboratories, Inc. ("Zenith") regarding terazosin hydrochloride. During the first quarter of 2000, two of these lawsuits, SCAFANI V. ABBOTT and VALENTINE V. ABBOTT, were removed from state court to the United States District Court for the Southern District of Florida. In addition, four new lawsuits were filed. Three of these new lawsuits are pending in the United States District Court for the Southern District of Florida: on January 19, 2000, William Mednick filed a lawsuit on behalf of himself and others; on January 27, 2000, Clarence Reid filed a lawsuit on behalf of himself and others; and, on April 7, 2000, Blue Cross and Blue Shield of Alabama filed a lawsuit on behalf of itself and others. The plaintiffs in the REID and MEDNICK lawsuits allege Abbott violated antitrust and/or consumer protection laws and seek actual damages, treble damages, civil penalties and other relief. The plaintiffs in the BLUE CROSS case allege Abbott violated federal racketeering statutes and seek unspecified damages. The BLUE CROSS case purports to be a class action.

Finally, on April 10, 2000, Merit Aid Pharmacy filed a lawsuit on behalf of itself and others in San Diego Superior Court, San Diego, California, alleging Abbott violated antitrust laws and seeking actual damages, treble damages, civil penalties and other relief. Abbott also reported that the Federal Trade Commission was conducting an investigation regarding Abbott's agreements with Geneva and Zenith. On March 13, 2000, Abbott and the Federal Trade Commission entered into a consent agreement regarding this matter which has been placed in the public record for comments. In its 1999 Form 10-K, Abbott reported that eighteen lawsuits, including five derivative lawsuits, were pending relating to Abbott's alleged noncompliance with the Food and Drug Administration's Quality System Regulation at Abbott's Diagnostics Division facilities in Lake County, Illinois. During the first quarter of 2000, the plaintiff in SEINFELD V. ABBOTT filed a lawsuit in the United States District Court for the Northern District of Illinois, where it was consolidated with the three other shareholder derivative lawsuits that were already pending in that court as IN RE ABBOTT LABORATORIES DERIVATIVE SHAREHOLDER LITIGATION and then voluntarily dismissed his lawsuit that was pending in Illinois state court. The fifth shareholder derivative suit was filed by Craig Heneghan and Marjory Motiaytis in the Circuit Court for the Nineteenth Judicial Circuit, Lake County, Illinois. On April 6, 2000, the Lake County Circuit Court granted Abbott's motion to stay the Heneghan/Motiaytis lawsuit until the shareholder derivative suits pending in federal court are decided. One new case relating to the alleged regulatory noncompliance was filed in the first quarter of 2000. On February 7, 2000, Lena Gallagher sued Abbott and Miles White, Abbott's Chief Executive Officer, claiming the defendants violated Sections 10(b) and 20(a) of the Securities and Exchange Act of 1934 by allegedly misrepresenting or omitting material information about the alleged regulatory noncompliance. The complaint, which was filed in the United States District Court for the Eastern District of Illinois, purports to be a class action on behalf of purchasers of ALZA Corporation stock between June 22, 1999 and November 1, 1999, and seeks unspecified monetary damages and relief. The United States Department of Justice is investigating the marketing and sales practices of TAP Pharmaceutical Products Inc. for leuprolide acetate depot suspension (a drug TAP markets as Lupron Depot-Registered Trademark-). Various state and federal agencies including the Office of the Inspector General, the United States Department of Justice and the Texas Attorney General, are also investigating the pricing practices of TAP with respect to Lupron Depot and/or of Abbott with respect to certain other Medicare and Medicaid reimbursable products. These investigations seek to determine whether these practices resulted in any violations of civil and/or criminal laws, including the Federal False Claims Act and the Anti-Kickback Act, or fraud in connection with the Medicare and/or Medicaid reimbursement paid to third parties. Abbott owns 50 percent of TAP. 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 the Company's financial position, cash flows, or results of operations.

The address of the registered office may be changed from time to time by the Board of Directors. ARTICLE II SHAREHOLDERS SECTION 1. ANNUAL MEETING; TRANSACTION OF BUSINESS, NOMINATION OF DIRECTORS. The annual meeting of the shareholders shall be held in the month of April in each year on such date and at such time as the Board of Directors shall provide. The meeting shall be held for the purpose of electing Directors and for the transaction of such other business as is properly brought before the meeting in accordance with these By-Laws. If the election of Directors shall not be held on the day designated for any annual meeting, or at any adjournment thereof, the Board of Directors shall cause the election to be held at a meeting of the shareholders as soon thereafter as conveniently may be. To be properly brought before the meeting, business must be either (a) specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors, (b) otherwise properly brought before the meeting by or at the direction of the Board of Directors or (c) otherwise properly brought before the meeting by a shareholder. In addition to any other applicable requirements, for business to be properly brought before an annual meeting by a shareholder, the shareholder must have given timely notice thereof in writing to the Secretary. To be timely, a shareholder's notice must be delivered to or mailed and received at the principal office of the Corporation, not earlier than October 1 nor later than the first business day of January immediately prior to the date of the meeting; PROVIDED, HOWEVER, that in the event that the date of such meeting is not in the month of April and less than sixty-five days' notice or prior public disclosure of the date of the meeting is given or made to shareholders, notice by the shareholder to be timely must be so received not later than the close of business on the fifteenth day following the day on which such notice of the date of the annual meeting was mailed or such public disclosure was made, whichever first occurs. A shareholder's notice to the Secretary shall set forth as to each matter the shareholder proposes to bring before the annual meeting (i) a brief

BY-LAWS description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (ii) the name and record address of the shareholder proposing such business, (iii) the class and number of shares of the Corporation which are beneficially owned by the shareholder and (iv) any material interest of the shareholder in such business. Notwithstanding anything in these By-Laws to the contrary, no business shall be conducted at the annual meeting except in accordance with the procedures set forth in this Section 1, PROVIDED, HOWEVER, that nothing in this Section 1 shall be deemed to preclude discussion by any shareholder of any business properly brought before the annual meeting. The Chairman of an annual meeting shall, if the facts warrant, determine and declare to the meeting that business was not properly brought before the meeting in accordance with the provisions of this Section 1, and if he should so determine, he shall so declare to the meeting and such business not properly brought before the meeting shall not be transacted. Only persons who are nominated in accordance with the following procedures shall be eligible for election as directors. Nominations of persons for election to the Board of Directors of the Corporation at the annual meeting may be made at such annual meeting of shareholders by or at the direction of the Board of Directors, by any nominating committee or person appointed by the Board of Directors, or by any shareholder of the Corporation entitled to vote for the election of directors at such meeting who complies with the notice procedures set forth in this Section 1. Such nominations, other than those made by or at the direction of the Board of Directors or by a committee or person appointed by the Board of Directors, shall be made pursuant to timely notice in writing to the Secretary. To be timely, a shareholder's notice shall be delivered to or mailed and received at the principal office of the Corporation not earlier than October 1 nor later than the first business day of January immediately prior to the date of the meeting; PROVIDED, HOWEVER, that in the event that the date of such meeting is not in the month of April and less than sixty-five days' notice or prior public disclosure of the date of the meeting is given or made to shareholders, notice by the shareholder to be timely must be so received not later than the close of business on the fifteenth day following the day on which such notice of the date of the meeting was mailed or such public disclosure was made, whichever first occurs.

The Corporation may require any proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine the eligibility of such proposed nominee to serve as

BY-LAWS director of the Corporation. No person shall be eligible for election as a director of the Corporation unless nominated in accordance with the procedures set forth herein. The Chairman of the meeting shall, if the facts warrant, determine and declare to the meeting that a nomination was not made in accordance with the foregoing procedure, and if he should so determine, he shall so declare to the meeting and the defective nomination shall be disregarded. SECTION 2. SPECIAL MEETINGS. Special meetings of the shareholders may be called by the Chairman of the Board, the Chief Executive Officer, the President, the Board of Directors or by the holders of not less than one-fifth of all the outstanding shares entitled to vote on the matter for which the meeting is called. SECTION 3. PLACE OF MEETING. The Board of Directors may designate any place, either within or without the State of Illinois, as the place of meeting for any annual meeting or for any special meeting called by the Board of Directors. If no designation is made, or if a special meeting be otherwise called, the place of meeting shall be the principal office of the Corporation in the State of Illinois. SECTION 4. NOTICE OF MEETINGS. Written notice stating the place, day and hour of the meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered not less than ten nor more than sixty days before the date of the meeting, or in the cases of a merger, consolidation, share exchange, dissolution or sale, lease or exchange of assets not less than twenty nor more than sixty days before the meeting, either personally or by mail, by or at the direction of the Chairman of the Board, the Chief Executive Officer, the President, or the Secretary or the persons calling the meeting, to each shareholder of record entitled to vote at such meeting. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail, addressed to the shareholder at his or her address as it appears on the records of the Corporation, with postage thereon prepaid. SECTION 5. FIXING RECORD DATE. For the purpose of determining shareholders entitled to notice of or to vote at any meeting of shareholders, or shareholders entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other proper purpose, the Board of Directors of the Corporation may fix in advance a date as the record date for any such determination of shareholders, such date in any case to be not more than sixty days and, for a meeting of shareholders, not less than ten days, or in the case of a merger, consolidation, share exchange, dissolution or sale, lease or exchange of assets not less than twenty days, immediately preceding such meeting. SECTION 6. VOTING LISTS. The Secretary shall make, or cause to have made, within twenty days after the record date for a meeting of shareholders or ten days before such meeting, whichever is earlier, a complete list of the shareholders entitled to vote at such meeting, arranged in alphabetical order, with the address of and the number of shares held by each, which list, for a period of ten days prior to such meeting, shall be kept on file at the registered office of the

BY-LAWS Corporation and shall be subject to inspection by any shareholder and to copying at the shareholder's expense, at any time during usual business hours. Such list shall also be produced and kept open at the time and place of the meeting and shall be subject to the inspection of any shareholder during the whole time of the meeting. The original share ledger or transfer book, or a duplicate thereof kept in this State, shall be prima facie evidence as to who are the shareholders entitled to examine such list or share ledger or transfer book or to vote at any meeting of shareholders. SECTION 7. QUORUM. A majority of the outstanding shares of the Corporation entitled to vote on a matter, represented in person or by proxy, shall constitute a quorum for consideration of such matter at a meeting of shareholders. If a quorum is present, the affirmative vote of the majority of the shares represented at the meeting and entitled to vote on a matter shall be the act of the shareholders, unless the vote of a greater number or voting by classes is required by The Business Corporation Act of 1983 or the Articles of Incorporation, as in effect on the date of such determination. If a quorum is not present, a majority of the shares of the Corporation entitled to vote on a matter and represented in person or by proxy at such meeting may adjourn the meeting from time to time without further notice. SECTION 8. PROXIES. A shareholder may appoint a proxy to vote or otherwise act for the shareholder by delivering a valid appointment to the person so appointed or such person's agent; PROVIDED, HOWEVER, no shareholder may name more than three persons as proxies to attend and to vote the shareholder's shares at any meeting of shareholders. Without limiting the manner in which a shareholder may appoint such a proxy pursuant to these By-Laws, the following shall constitute valid means by which a shareholder may make such an appointment: (a) A shareholder may sign a proxy appointment form. The shareholder's signature may be affixed by any reasonable means, including, but not limited to, by facsimile signature. (b) A shareholder may transmit or authorize the transmission of a telegram, cablegram, or other means of electronic transmission; provided that any such transmission must either set forth or be submitted with information from which it can be determined that the telegram, cablegram, or other electronic transmission was authorized by the shareholder. If it is determined that the telegram, cablegram, or other electronic transmission is valid, the inspectors or, if there are no inspectors, such other persons making that determination shall specify the information upon which they relied. No proxy shall be valid after the expiration of eleven months from the date thereof unless otherwise provided in the proxy. Each proxy continues in full force and effect until revoked by the person appointing the proxy prior to the vote pursuant thereto, except as otherwise provided by law. Such revocation may be effected by a writing delivered to the secretary of the Corporation stating that the proxy is revoked or by a subsequent delivery of a valid proxy by, or

BY-LAWS by the attendance at the meeting and voting in person by the person appointing the proxy. The dates of the proxy shall presumptively determine the order of appointment. SECTION 9. VOTING OF SHARES. Each outstanding share, regardless of class, shall be entitled to one vote in each matter submitted to a vote at a meeting of shareholders and, in all elections for Directors, every shareholder shall have the right to vote the number of shares owned by such shareholder for as many persons as there are Directors to be elected, or to cumulate such votes and give one candidate as many votes as shall equal the number of Directors multiplied by the number of such shares or to distribute such cumulative votes in any proportion among any number of candidates; provided that, vacancies on the Board of Directors may be filled as provided in Section 9, Article III of these By-Laws. A shareholder may vote either in person or by proxy. SECTION 10. VOTING OF SHARES BY CERTAIN HOLDERS. Shares of this Corporation held by the Corporation in a fiduciary capacity may be voted and shall be counted in determining the total number of outstanding shares entitled to vote at any given time. Shares registered in the name of another corporation, domestic or foreign, may be voted by any officer, agent, proxy or other legal representative authorized to vote such shares under the law of incorporation of such corporation. Shares registered in the name of a deceased person, a minor ward or a person under legal disability may be voted by his or her administrator, executor, or court appointed guardian, either in person or by proxy without a transfer of such shares into the name of such administrator, executor, or court appointed guardian. Shares registered in the name of a trustee may be voted by him or her, either in person or by proxy. Shares registered in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without the transfer thereof into his or her name if authority so to do is contained in an appropriate order of the court by which such receiver was appointed. A shareholder whose shares are pledged shall be entitled to vote such shares until the shares have been transferred into the name of the pledgee, and thereafter the pledgee shall be entitled to vote the shares so transferred. SECTION 11. VOTING BY BALLOT. Voting on any question or in any election may be viva voce unless the presiding officer shall order that voting be by ballot. SECTION 12. INSPECTORS OF ELECTION. The Board of Directors in advance of any meeting of shareholders may appoint inspectors to act at such meeting or any adjournment thereof. If inspectors of election are not so appointed, the officer or person acting as chairman at any such meeting may, and on the request of any shareholder or his proxy, shall make such appointment. In case any person appointed as inspector shall fail to appear or to act, the vacancy

BY-LAWS may be filled by appointment made by the Board of Directors in advance of the meeting or at the meeting by the officer or person acting as chairman. Such inspectors shall ascertain and report the number of shares represented at the meeting, based upon their determination of the validity and effect of proxies; count all votes and report the results; and do such other acts as are proper to conduct the election and voting with impartiality and fairness to all the shareholders. Each report of an inspector shall be in writing and signed by him or her or by a majority of them if there be more than one inspector acting at such meeting. If there is more than one inspector, the report of a majority shall be the report of the inspectors. The report of the inspector or inspectors on the number of shares represented at the meeting and the results of the voting shall be prima facie evidence thereof. ARTICLE III DIRECTORS SECTION 1. GENERAL POWERS. The business and affairs of the Corporation shall be managed under the direction of the Board of Directors. SECTION 2. NUMBER, TENURE AND QUALIFICATIONS. The number of Directors of the Corporation shall be twelve. The terms of all Directors shall expire at the next annual meeting of shareholders following their election.

The Board of Directors may provide, by resolution, for the holding of the regular monthly meetings at a different time and place, either within or without the State of Illinois, or for the omission of the regular monthly meeting altogether. Where the Board of Directors has, by resolution, changed or omitted regular meetings, no other notice than such resolution shall be given. SECTION 4. SPECIAL MEETINGS. Special meetings of the Board of Directors may be called by or at the request of the Chairman of the Board, the Chairman of the Executive Committee, the Chief Executive Officer, the President, or of any four Directors.

BY-LAWS SECTION 5. NOTICE. Notice of any special meeting shall be given: (i) at least one day prior thereto if the notice is given personally or by an electronic transmission, (ii) at least two business days prior thereto if the notice is given by having it delivered by a third party entity that provides delivery services in the ordinary course of business and guarantees delivery of the notice to the Director no later than the following business day, and (iii) at least seven days prior thereto if the notice is given by mail. For this purpose, the term "electronic transmission" may include, but shall not be limited to, a telex, facsimile, or other electronic means. Notice shall be delivered to the Director's business address and/or telephone number and shall be deemed given upon electronic transmission, upon delivery to the third party delivery service, or upon being deposited in the United States mail with postage thereon prepaid. Any Director may waive notice of any meeting by signing a written waiver of notice either before or after the meeting. Attendance of a Director at any meeting shall constitute a waiver of notice of such meeting, except where a Director attends a meeting for the express purpose of objecting to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Board of Directors need to be specified in the notice or waiver of notice of such meeting. SECTION 6. QUORUM. A majority of the number of Directors fixed by these By-Laws shall constitute a quorum for transaction of business at any meeting of the Board of Directors; provided, that if less than a majority of such number of Directors are present at said meeting, a majority of the Directors present may adjourn the meeting from time to time without further notice. SECTION 7. MANNER OF VOTING. The act of the majority of the Directors present at a meeting at which a quorum is present shall be the act of the Board of Directors. SECTION 8. INFORMAL ACTION BY DIRECTORS. Any action required to be taken at a meeting of the Board of Directors, or any other action which may be taken at a meeting of the Board of Directors or a committee thereof, may be taken without a meeting if a consent in writing, setting forth the action so taken, shall be signed by all of the Directors entitled to vote with respect to the subject matter thereof, or by all the members of such committee, as the case may be. The consent shall be evidenced by one or more written approvals, each of which sets forth the action taken and bears the signature of one or more Directors. All the approvals evidencing the consent shall be delivered to the Secretary of the Corporation to be filed in the corporate records. The action taken shall be effective when all the Directors have approved the consent unless the consent specifies a different effective date. Any such consent signed by all the Directors or all the members of a committee shall have the same effect as a unanimous vote. SECTION 9. VACANCIES. Any vacancy occurring in the Board of Directors and any directorship to be filled by reason of an increase in the number of Directors, may be filled by

BY-LAWS election at an annual meeting or at a special meeting of shareholders called for that purpose. A Director elected to fill a vacancy shall serve until the next annual meeting of shareholders. A majority of Directors then in office may also fill one or more vacancies arising between meetings of shareholders by reason of an increase in the number of Directors or otherwise, and any Director so selected shall serve until the next annual meeting of shareholders, provided that at no time may the number of Directors selected to fill vacancies in this manner during any interim period between meetings of shareholders exceed 33-1/3 per cent of the total membership of the Board of Directors. SECTION 10. PRESUMPTION OF ASSENT. A Director of the Corporation who is present at a meeting of the Board of Directors or any committee thereof at which action on any corporate matter is taken is conclusively presumed to have assented to the action taken unless his or her dissent is entered in the minutes of the meeting or unless he or she files his or her written dissent to such action with the person acting as the secretary of the meeting before the adjournment thereof or forwards such dissent by registered or certified mail to the Secretary of the Corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to a Director who voted in favor of such action. SECTION 11. APPOINTMENT OF AUDITORS. Upon the recommendation of the Audit Committee, the Board of Directors shall appoint annually a firm of independent public accountants as auditors of the Corporation. Such appointment shall be submitted to the shareholders for ratification at the Annual Meeting next following such appointment. Should the holders of a majority of the shares represented at the meeting fail to ratify the appointment of any firm as auditors of the Corporation, or should the Board of Directors for any reason determine that such appointment be terminated, the Board of Directors shall appoint another firm of independent public accountants to act as auditors of the Corporation and such appointment shall be submitted to the shareholders for ratification at the Annual or Special Shareholders Meeting next following such appointment. ARTICLE IV COMMITTEES SECTION 1. APPOINTMENT. A majority of the Board of Directors may create one or more committees and appoint members of the Board to serve on the committee or committees.
