Upon the approval of the committee of two or more directors of the Company (the "Committee") responsible for administration of the Plan, some or all of a Participant's Stock Options may be transferred by such Participant pursuant to a domestic relations order. Each transfer must be made in accordance with the grant documents specifying the terms and conditions for transferring such Stock Options. This prospectus also relates to the offer and sale of Common Stock pursuant to such Stock Options to the beneficiaries of such permitted transferees, or the executors or administrators of their estates, or other persons duly authorized by law to administer the estate or assets of such persons. As set forth in the Assignment of Option to Purchase Common Stock and agreed to by each person who acquires a Participant's Stock Options pursuant to a domestic relations order, the Company reserves the right to suspend this offering at any time if, in the Company's judgment, a sale of Common Stock may violate federal securities laws. THE COMPANY Bone Care is a leader in the discovery and development of improved vitamin D-hormone ("D-hormone") therapies. D-hormones have a key role in secondary hyperparathyroidism leading to metabolic bone diseases in several patient populations, including end stage renal disease ("ESRD"), pre-dialysis and osteoporosis patients. D-hormones also have a role in certain hyperproliferative diseases, including prostate, breast and colon cancers, and psoriasis. In March 1998, the Company filed a New Drug Application ("NDA") with the United States Food and Drug Administration ("FDA") for an oral formulation of its lead product candidate, one-alpha D2 (Hectorol ), a synthetic D- hormone analog for the treatment of secondary hyperparathyroidism associated with ESRD. In February 1999, the Company submitted a NDA with the FDA for an intravenous formulation of Hectorol for the same indication. USE OF PROCEEDS The Company intends to use the net proceeds from the sale of the Common Stock for general corporate purposes. DESCRIPTION OF THE PLAN AND THE STOCK OPTIONS The Plan - -------- The purpose of the Plan is to provide incentives to officers, key employees and consultants of the Company and its subsidiaries and members of the Board of Directors to contribute to the success and prosperity of the Company by granting Stock Options to such persons. The Plan was initially adopted as of February 1, 1996. Under the Plan, a total of 1,000,000 shares of Common Stock were made available for grant. Only nonqualified stock options may be granted under the Plan. The option price per share of Common Stock purchasable upon exercise of an option is 100% of the fair market value of a share of Common Stock on the date of grant of such stock option. The Plan is administered by the Committee, which has the authority, subject to the terms of the Plan, to establish eligibility guidelines, select officers, key employees, consultants, and non-employee directors for participation in the Plan and determine the number of shares of Common Stock subject to a stock option, the exercise price for such shares of Common Stock, the time and conditions of vesting or exercise, and all other terms and conditions of the stock options. To the extent required under Section 162(m) of the Internal Revenue Code of 1986, and the rules and regulations thereunder, the maximum number of shares of Common Stock with respect to which options may be granted during any calendar year to any person is 200,000, subject to adjustment for changes in the Company's capitalization. The Plan may be amended by the Board of Directors in any respect, except that no amendment may be made without shareholder approval if such amendment would increase the maximum number of shares of Common Stock available under the Plan (other than certain adjustments for changes in the Company's capitalization) or would otherwise require shareholder approval. The Plan will terminate on February 1, 2006, unless earlier terminated by the Board of Directors. The Stock Options - ----------------- At the time of grant, the Committee establishes the exercise price, the expiration date and the times and installments in which the Stock Options may be exercised. As of the date of this prospectus, all Stock Options granted under the Plan have had expiration dates ten years from the date of grant with an exercise price equal to 100% of the fair market value of a share of Common Stock on the date of grant. Such grants generally have provided that the Stock Options become exercisable in equal annual installments over the three-year or five-year period following the date of grant. If any change shall occur in or affect shares of Common Stock or Stock Options on account of a merger, reorganization, stock dividend, stock split or similar changes, the Committee shall make adjustments in, among other things, (i) the number of shares exercisable under each Stock Option and (ii) the exercise price of the unexercised portion of each Stock Option. Transferability - --------------- The Plan provides that Stock Options are generally not transferable by a Participant except by will or the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company and are exercisable during the Participant's lifetime only by the Participant. Notwithstanding the foregoing, under certain circumstances, the Committee may consent to the transfer or transferability of any particular Stock Option in the manner approved by the Committee. The Committee has determined to allow the transfer of certain Stock Options pursuant to a domestic relations order. Any such permitted transferee of a Participant's Stock Options shall be referred to herein as a "Stock Option Transferee" and such Participant shall be referred to herein as a "Participant Transferor." This prospectus relates to up to 50,000 shares of Common Stock which may be offered and sold to Stock Option Transferees pursuant to Stock Options that may be transferred as described in the immediately preceding paragraph. This prospectus also relates to the offer and sale of Common Stock pursuant to such Stock Options to the beneficiaries of such Stock Option Transferees or the executors or administrators of their estates, or other persons duly authorized by law to administer the estate or assets of such persons. Upon transfer to a Stock Option Transferee, a Stock Option is governed by and subject to the terms and limitations of the Plan and the relevant grant, as such grant may be amended by the Committee in consenting to a transfer of the Stock Option, and, subject to any such amendment, the Stock Option Transferee is entitled to the same rights as the Participant Transferor, as if no transfer had taken place. ACCORDINGLY, THE RIGHTS OF THE STOCK OPTION TRANSFEREE ARE SUBJECT TO THE TERMS AND CONDITIONS OF THE ORIGINAL GRANT TO THE PARTICIPANT TRANSFEROR, AS AMENDED, INCLUDING PROVISIONS RELATING TO EXPIRATION DATE, EXERCISABILITY, EXERCISE PRICE AND FORTEITURE. FOR INFORMATION REGARDING THE TERMS OF A PARTICULAR STOCK OPTION GRANT, STOCK OPTION TRANSFEREES MAY CONTACT THE CORPORATE SECRETARY AT THE COMPANY'S PRINCIPAL EXECUTIVE OFFICES. Once a Stock Option has been transferred to a Stock Option Transferee, it may not be subsequently transferred by the Stock Option Transferee except with the consent of the Committee or by will or the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company. Exercise of Stock Options by Stock Option Transferees - ----------------------------------------------------- A Stock Option that has been validly transferred may be exercised by the Stock Option Transferee at any time from the time first set by the Committee in the original grant to the Participant Transferor until the close of business on the expiration date of the Stock Option, or the earlier date on which the Stock Option terminates due to the Participant Transferor's termination of employment or service as director, as discussed below. Stock Options generally become exercisable in equal annual installments over the three-year or five-year period following the date of grant. The exercise price of the shares as to which Stock Options are exercised shall be paid to the Company at the time of exercise in cash. A Stock Option will be deemed exercised on the date the Company's Corporate Secretary's office has received written notice of exercise of the Stock Option signed by the Stock Option Transferee specifying the number of shares of Common Stock being purchased pursuant to the Stock Option exercise (accompanied by a check in satisfaction of the exercise price). The Stock Option shares will generally be registered in the name of the Stock Option Transferee as of the first business day following the date the Company receives a properly completed notice of exercise and payment of the exercise price and an amount necessary to satisfy all income tax withholding obligations. Any required income tax withholding must be satisfied by the Stock Option Transferee as discussed below under the heading "CERTAIN FEDERAL INCOME TAX CONSEQUENCES." Once the exercise is completed as described above, stock certificates for the appropriate number of shares will be delivered as soon as practicable to the Stock Option Transferee or his or her estate or beneficiaries, or such shares shall otherwise be delivered in such manner as the person(s) entitled thereto may direct. Effect of Termination of Employment or Service - ---------------------------------------------- Because Stock Options transferred to Stock Option Transferees continue to be governed by the terms of the Plan and the original grant, their exercisability continues to be affected by the Participant Transferor's employment or service status. If a Participant Transferor terminates employment or service with the Company for any reason other than retirement after age 60 or death, all out- standing unexercised Stock Options granted to such Participant Transferor, including those transferred to a Stock Option Transferee, may be exercised during the 30-day period following the date of termination of employment or service, but only to the extent exercisable on the date of termination and in no event after the expiration dates of such Stock Options. If a Participant Transferor terminates employment or service by reason of retirement after age 60 or death, all outstanding unexercised Stock Options granted to such Participant Transferor, including those transferred to a Stock Option Transferee, may be exercised during the one-year period following the date of death or date of termination of employment or service, but only to the extent exercisable on the date of termination or death, and in no event after the expiration dates of such Stock Options. If a Participant Transferor dies during the 30-day period following termination of employment or service for any reason other than retirement after age 60, or if a Participant Transferor dies during the one-year period following termination of employment or service by reason of retirement after age 60, all outstanding unexercised Stock Options granted to such Participant Transferor, including those transferred to a Stock Option Transferee, may be exercised during the one-year period following the date of death, but only to the extent exercisable on the date of death, and in no event after the expiration dates of such Stock Options. The Company has no obligation to notify any Stock Option Transferee of the termination of employment or service of the Participant Transferor. Change in Control - ----------------- In the event of a change in control of the Company, any stock option not previously exercisable in full will become fully exercisable. A change in control generally is the acquisition, subject to certain exceptions, by any person of beneficial ownership of 50% or more of the outstanding shares of Common Stock, a change in the majority of the Board of Directors and approval by the shareholders of a reorganization, merger, consolidation, or sale of all or substantially all of the assets of the Company unless certain conditions are satisfied. CERTAIN FEDERAL INCOME TAX CONSEQUENCES Prior to making a transfer of a Stock Option, a Participant should consult with his or her personal tax advisors concerning the possible federal, state and local income and other tax consequences of such a transfer. A Stock Option Transferee should consult with his or her personal tax advisors concerning the possible federal, state and local income and other tax consequences of the exercise of a Stock Option. The federal income tax consequences of a transfer to a former spouse of a Stock Option pursuant to a domestic relations order and of the exercise of the Stock Option are summarized below. State and local income tax consequences are not addressed herein. Income Tax Consequences for Participant Transferor - -------------------------------------------------- A Participant who transfers a Stock Option to a Stock Option Transferee pursuant to a domestic relations order will not recognize income at the time of the transfer. As discussed in the following paragraph, where the Participant Transferor and the Stock Option Transferee both are domiciled in a community property state, such as Wisconsin, the Stock Option Transferee and not the Participant Transferor will recognize ordinary income at the time the Stock Option Transferee exercises the Stock Option. Income Tax Consequences for Stock Option Transferee - --------------------------------------------------- A Stock Option Transferee will not recognize income at the time a Stock Option is transferred to the Stock Option Transferee pursuant to a domestic relations order. Where the Participant Transferor and the Stock Option Transferee are both domiciled in a community property state, such as Wisconsin, upon exercise of a Stock Option that was transferred pursuant to a domestic relations order, the Stock Option Transferee will recognize ordinary income in an amount equal to the excess of the fair market value of the shares purchased on the date of exercise (which will not necessarily be equal to the price at which such shares are sold, even if sold on the same day as exercise) over the exercise price. If either the Participant Transferor or the Stock Option Transferee is not domiciled in a community property state, the Participant Transferor and Stock Option Transferee should consult their personal tax advisors. The Company will generally be entitled to claim a federal income tax deduction at such time and in the same amount that the Stock Option Transferee recognizes ordinary income. The Internal Revenue Service has ruled in private letter rulings that the amount required to be included in income by the Stock Option Transferee is subject to income tax withholding. Income Tax Consequences upon the Subsequent Sale of Stock - --------------------------------------------------------- If shares acquired upon exercise of a Stock Option that was transferred pursuant to a domestic relations order are later sold or exchanged, then the difference between the sale price and the Stock Option Transferee's tax basis for the shares will generally be taxable as long-term or short-term capital gain or loss (assuming that the stock is a capital asset of the taxpayer) depending upon whether the stock has been held for more than 12 months after the exercise date. The tax basis for the shares in the hands of the Stock Option Transferee would be the exercise price for the Stock Option plus the amount of income recognized by the Stock Option Transferee at the time of exercise. DESCRIPTION OF CAPITAL STOCK The authorized capital stock of the Company consists of 28,000,000 shares of Common Stock, no par value, and 2,000,000 shares of Preferred Stock, par value $.001 per share. The Board of Directors of the Company has designated 140,000 shares of the Preferred Stock as Series A Junior Participating Preferred Stock in connection with the Rights described below. The following summary description of the capital stock of the Company is qualified in its entirety by reference to the Articles of Incorporation and the By-Laws of the Company, which are filed as exhibits to the Registration Statement on Form S-3 (the "Registration Statement") filed by the Company with the Securities and Exchange Commission (the "SEC"). Common Stock - ------------ Holders of Common Stock are entitled to one vote for each share held on all matters submitted to a vote of shareholders. Holders of Common Stock do not have cumulative voting rights in the election of directors and have no preemptive, subscription or redemption rights. All outstanding shares of Common Stock are validly issued, fully paid and nonassessable, except for certain statutory liabilities which may be imposed by Section 180.0622 of the WBCL for unpaid employee wages. Section 180.0622 of the WBCL provides that shareholders of every corporation are personally liable to an amount equal to the par value of the shares owned by them and to the consideration for which their shares without par value were issued, for all debts owing to employees for services performed for such corporation, but not exceeding six months' service in the case of any individual employee. The Common Stock has no par value. Holders of Common Stock are entitled to such dividends as may be declared by the Board of Directors out of funds legally available therefor. Upon liquidation, dissolution or winding-up of the Company, the assets legally available for distribution to shareholders are distributable ratably among the holders of Common Stock at that time outstanding subject to prior distribution rights of creditors of the Company. Preferred Stock - --------------- The Articles of Incorporation provide that the Board of Directors of the Company is authorized, subject to certain limitations prescribed by law or the rules of The Nasdaq Stock Market, to issue, without further shareholder approval, up to 2,000,000 shares of Preferred Stock of the Company, to determine with respect to the Preferred Stock the preferences, limitations and relative rights, in whole or in part, before the issuance of any shares of Preferred Stock, to create one or more series of Preferred Stock, and, with respect to any series, to determine the number of shares of the series, the distinguishing designation and the preferences, limitations and relative rights, in whole or in part, before the issuance of any shares of that series. In connection with the adoption of the Company's shareholders rights plan, the Board of Directors of the Company designated 140,000 shares as the Series A Junior Participating Preferred Stock. Rights Agreement - ---------------- The Board of Directors has adopted a shareholders rights plan. Under the shareholders rights plan, each share of Common Stock has associated with it one preferred share purchase right (a "Right"). The terms of the Preferred Rights are set forth in a Rights Agreement (the "Rights Agreement") between the Company and Norwest Bank Minnesota, N.A. The following summary description of the Rights and the Rights Agreement is qualified in its entirety by reference to the Rights Agreement, which is filed as an exhibit to the Registration Statement. Under certain circumstances described below, each Right would entitle the holder thereof to purchase one two-hundredth of a share of Series A Junior Participating Preferred Stock for a price of $12.50 per one two-hundredth of a share, subject to adjustment. The Rights are not presently exercisable and are transferable only with the related shares of Common Stock. The Rights will not become exercisable or be evidenced by separate certificates or trade separately from the Common Stock prior to the occurrence of certain triggering events described below. In such an event, separate Rights certificates would be issued and distributed representing one Right for each share of Common Stock. There is no present market for the Rights separate from the Common Stock and the Company cannot predict whether a trading market would develop with respect to the Rights if the Rights ever become exercisable. The Rights would become exercisable at the specified exercise price upon the earliest to occur of (i) 10 business days after the first public announcement that any person or group (other than an Exempt Person, as defined below) has acquired beneficial ownership of 15% or more of the Company's outstanding shares of Common Stock (an "Acquiring Person") and (ii) 10 business days (unless delayed by the Board of Directors) after any person or group (other than an Exempt Person) has commenced, or announced the intention to commence, a tender or exchange offer which would, upon its consummation, result in such person or group being the beneficial owner of 15% or more of the outstanding shares of Common Stock (the earliest of such date is the "Distribution Date"). Rights certificates will be distributed as soon as practicable after the Distribution Date. Notwithstanding the foregoing, Rights may not be exercised following the occurrence of an event described below under the caption "Flip-In" prior to the expiration of the Company's right to redeem the Rights. An "Exempt Person" includes the Company, Dr. Mazess and certain persons and entities related to or affiliated with the Company or Dr. Mazess. FLIP-IN. After the Rights become exercisable and a person or group has become an Acquiring Person, the holders of the Rights (other than an Acquiring Person and certain transferees therefrom) would be entitled to purchase shares of Common Stock at a 50% discount. After the occurrence of a "Flip-In" event, the Rights of an Acquiring Person and such transferees become void. FLIP-OVER. In the event that, on or after the date on which an Acquiring Person has become such: (i) the Company merges into or consolidates with an Interested Shareholder (as defined below) or, unless all holders of the outstanding shares of Common Stock are treated the same, any other person (with limited designated exceptions), (ii) an Interested Shareholder or, unless all holders of the outstanding shares of Common Stock are treated the same, any other person (with limited designated exceptions) merges into the Company or (iii) the Company sells or transfers 50% or more of its consolidated assets or earning power to an Interested Shareholder or, unless all holders of the outstanding shares of Common Stock are treated the same, any other person (with limited designated exceptions), the holders of the Rights (other than Rights which have become void) would be entitled to purchase common shares of the acquiror (or a person affiliated therewith) at a 50% discount. In general, an "Interested Shareholder" is an Acquiring Person and certain persons affiliated, associated or acting on behalf of or in concert therewith. REDEMPTION OF RIGHTS. The Rights may be redeemed, in whole but not in part, at a redemption price of $.005 per Right, subject to adjustment, at the direction of the Board, at any time prior to the earliest of (i) 10 business days after the first public announcement that any person or group has become an Acquiring Person, (ii) the occurrence of any transaction described under the caption "Flip-Over" and (iii) April 13, 2006. Under certain circumstances set forth in the Rights Agreement, redemption requires that disinterested directors be in office and that the decision to redeem the Rights have the concurrence of at least a majority of the disinterested directors after the occurrence of an event. Such circumstances include redeeming the Rights (i) at a time at which there is an Acquiring Person or (ii) after the first public announcement that a person or group has become an Acquiring Person but prior to the occurrence of a transaction described under the caption "Flip-Over," but only (i) if the person who is the Acquiring Person shall have reduced its beneficial ownership of the then outstanding shares of Common Stock to less than 10% or (ii) in connection with any transaction described under the caption "Flip-Over" which does not involve an Interested Shareholder and in which all holders of the Common Stock are treated the same. EXCHANGE OF SHARES FOR RIGHTS. At any time after any person or group shall have become an Acquiring Person and before any person (other than an Exempt Person), together with its affiliates and associates, shall have become the beneficial owner of 50% or more of the outstanding shares of Common Stock, the Board of Directors may, at its option, exchange all or any part of the Rights (other than Rights which have become void) for shares of Common Stock at the exchange rate of one share of Common Stock (or one two-hundredth of a Preferred Share) per Right, subject to adjustment. Terms of Series A Junior Participating Preferred Stock - ------------------------------------------------------ The Series A Junior Participating Preferred Stock (the "Preferred Shares") which would be issuable upon exercise of the Rights (should the Rights become exercisable) would not be redeemable. Each Preferred Share would entitle the holder thereof to receive a preferential quarterly dividend equal to 200 times the aggregate per share amount of all cash dividends, plus 200 times the aggregate per share amount (payable in kind) of all non-cash dividends and other distributions (other than in shares of Common Stock), declared on the Common Stock during such quarter, adjusted to give effect to any dividend on the Common Stock payable in shares of Common Stock or any subdivision, combination or reclassification of the Common Stock (a "Dilution Event"). Each Preferred Share would entitle the holder thereof to 200 votes on all matters submitted to a vote of the shareholders of the Company, voting together as a single class with the holders of the Common Stock and the holders of any other class of capital stock having general voting rights, adjusted to give effect to any Dilution Event. In the event of liquidation of the Company, the holder of each Preferred Share would be entitled to receive a preferential liquidation payment equal to 200 times the aggregate per share amount to be distributed to the holders of the Common Stock, adjusted to give effect to any Dilution Event, plus an amount equal to accrued and unpaid dividends and distributions on such Preferred Share, whether or not declared, to the date of such payment. In the event of any merger, consolidation or other transaction in which the outstanding shares of Common Stock are exchanged for or converted into other capital stock, securities, cash and/or other property, each Preferred Share would be similarly exchanged or converted into 200 times the per share amount applicable to the Common Stock, adjusted to give effect to any Dilution Event. LEGAL MATTERS The validity of the shares of Common Stock offered hereby will be passed upon for the Company by Michael, Best & Friedrich, Milwaukee, Wisconsin.

Indemnification of Directors and Officers. - ---------------------------------------------------- Under the Company's By-Laws, directors and officers of the Company are entitled to mandatory indemnification from the Company against certain liabilities and expenses (a) to the extent such officers or directors are successful in the defense of a proceeding and (b) in proceedings in which the director or officer is not successful in the defense thereof, unless it is determined the director or officer breached or failed to perform such person's duties to the Company and such breach or failure constituted: (i) a willful failure to deal fairly with the Company or its shareholders in connection with a matter in which the director or officer had a material conflict of interest, (ii) a violation of criminal law, unless the director or officer had reasonable cause to believe his or her conduct was lawful or had no reasonable cause to believe his or her conduct was unlawful, (iii) a transaction from which the director or officer derived an improper personal profit, or (iv) willful misconduct. The Company's By-Laws provide that the Company may purchase and maintain insurance on behalf of an individual who is a director or officer of the Company against liability asserted against or incurred by such individual in his or her capacity as a director or officer regardless of whether the Company is required or authorized to indemnify or allow expenses to the individual against the same liability under the By-Laws. The Wisconsin Business Corporation Law contains provisions for mandatory indemnification of directors and officers against certain liabilities and expenses that are similar to those contained in the Company's By-Laws. Under Section 180.0828 of the Wisconsin Business Corporation Law, directors of the Company are not subject to personal liability to the Company, its shareholders or any person asserting rights on behalf thereof for damages, settlements, fees, fines, penalties or other monetary liabilities arising from breaches or failures to perform any duty resulting solely from their status as such directors, except in circumstances paralleling those in clauses (i) through (iv) in the preceding paragraph. These provisions pertain only to breaches of duty by directors as directors and not in any other corporate capacity, such as officers. As a result of such provisions, shareholders may be unable to recover monetary damages against directors for actions taken by them which constitute negligence or gross negligence or which are in violation of their fiduciary duties, although it may be possible to obtain injunctive or other equitable relief with respect to such actions. If equitable remedies are found not to be available to shareholders in any particular case, shareholders may not have any effective remedy against the challenged conduct. The Company has purchased directors and officers liability insurance, which would provide coverage against certain liabilities including liabilities under the Securities Act of 1933, as amended (the "Securities Act"). Item 16. Exhibits. - ------------------- A list of exhibits included as part of this Registration Statements is set forth in the Exhibit Index appearing elsewhere herein and is incorporated herein by reference. Item 17. 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 end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 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 in 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 that 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. (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 Section 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 foregoing provisions, 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 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by 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 Act and will be governed by the final adjudication of such issue. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Madison, State of Wisconsin, on this 3rd day of February, 1999.
