Item 4. Description of Securities Not applicable. Item 5. Interests of Named Experts and Counsel Counsel acts as a legal consultant for the Company from time to time. Item 6. Indemnification of Directors and Officers Section 102 of the Delaware General Corporation Law allows a corporation to eliminate the personal liability of directors of a corporation to the corporation or to any of its stockholders for monetary damage for a breach of his fiduciary duty as a director, except in the case where the director breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Calypte's Certificate of Incorporation contains a provision that eliminates directors' personal liability as set forth above. 3 Section 145 of the Delaware General Corporation Law, as amended, provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation or is or was serving at its request in such capacity in another corporation or business associated against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Article VII of the Company's Amended and Restated Certificate of Incorporation provides for the indemnification of its directors to the fullest extent permitted by the Delaware General Corporation Law. This provision in the Amended and Restated Certificate of Incorporation does not eliminate the fiduciary duty of the directors, and, in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware Law. In addition, each director will continue to be subject to liability for breach of the director's duty of loyalty to the Company for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for actions leading to improper personal benefit to the director and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law. The provision does not affect a director's responsibilities under any other law, such as the federal securities laws or state or federal environmental laws. Article VI of the Company's Bylaws provides for the indemnification of officers, directors and third parties acting on behalf of the corporation to the full extent permitted by Delaware law. The Company has entered into Indemnification Agreements with its executive officers and directors. The Indemnification Agreements provide the Company's officers and directors with further indemnification to the maximum extent permitted by the Delaware General Corporation Law. Item 7. Exemption from Registration Claimed Not applicable. Item 8. Exhibits The Exhibits to this registration statement are listed in the index to Exhibits on page 9. Item 9.

(2) That for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendments 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 mean of a post-effective amendment any of the securities being registered hereunder that remain unsold at the termination of the offering. (b) The undersigned Company hereby undertakes that for purposes of determining any liability under the Securities Act of 1933, each filing of the company's annual report pursuant to Section 13 (a) or Section 15 (d) of the Securities and 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 Company pursuant to the above-described provisions or otherwise, the Company has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company 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 Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. 5 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 a form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Alameda, State of California on November 26, 2002.

The Company will not take any action which would result in any adjustment in the number of shares of Common Stock purchasable hereunder if the total number of shares of Common Stock issuable pursuant to the terms of this Warrant after such action upon full exercise of this Warrant and, together with all shares of Common Stock then outstanding and all shares of Common Stock then issuable upon exercise of all options and other rights to purchase shares of Common Stock then outstanding, would exceed the total number of shares of Common Stock then authorized by the Company's Restated and Amended Articles of Incorporation, as then amended. 46 4. The Initial Exercise Price is $.05 per share of Common Stock ("Initial Exercise Price"). The Initial Exercise Price shall be adjusted as provided for below in this Section 4 (the Initial Exercise Price, and the Initial Exercise Price, as thereafter then adjusted, shall be referred to as the "Exercise Price") and the Exercise Price from time to time shall be further adjusted as provided for below in this Section 4. Upon each adjustment of the Exercise Price, the Holder shall thereafter be entitled to receive upon exercise of this Warrant, at the Exercise Price resulting from such adjustment, the number of shares of Common Stock obtained by (i) multiplying the Exercise Price in effect immediately prior to such adjustment by the number of shares of Common Stock purchasable hereunder immediately prior to such adjustment, and (ii) dividing the product thereof by the Exercise Price resulting from such adjustment. The Exercise Price shall be adjusted as follows: (i) In the case of any amendment to the Company's Articles of Incorporation to change the designation of the Common Stock or the rights, privileges, restrictions or conditions in respect to the Common Stock or division of the Common Stock, this Warrant shall be adjusted so as to provide that upon exercise thereof, the Holder shall receive, in lieu of each share of Common Stock theretofore issuable upon such exercise, the kind and amount of shares, other securities, money and property receivable upon such designation, change or division by the Holder issuable upon such exercise had the exercise occurred immediately prior to such designation, change or division. This Warrant shall be deemed thereafter to provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 4. The provisions of this Subsection 4(i) shall apply in the same manner to successive reclassifications, changes, consolidations and mergers. (ii) If the Company shall at any time subdivide its outstanding shares of Common Stock into a greater number of shares of Common Stock, or declare a dividend or make any other distribution upon the Common Stock payable in shares of Common Stock, the Exercise Price in effect immediately prior to such subdivision or dividend or other distribution shall be proportionately reduced, and conversely, in case the outstanding shares of Common Stock shall be combined into a smaller number of shares of Common Stock, the Exercise Price in effect immediately prior to such combination shall be proportionately increased. 47 (iii) If any capital reorganization or reclassification of the capital stock of the Company, or any consolidation or merger of the Company with or into another corporation or other entity, or the sale of all or substantially all of the Company's assets to another corporation or other entity shall be effected in such a way that holders of shares of Common Stock shall be entitled to receive stock, securities, other evidence of equity ownership or assets with respect to or in exchange for shares of Common Stock, then, as a condition of such reorganization, reclassification, consolidation, merger or sale (except as otherwise provided below in this Section 4), lawful and adequate provisions shall be made whereby the Holder shall thereafter have the right to receive upon the exercise hereof upon the basis and upon the terms and conditions specified herein, such shares of stock, securities, other evidence of equity ownership or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of Common Stock immediately theretofore purchasable and receivable upon the exercise of this Warrant under this Section 4 had such reorganization, reclassification, consolidation, merger or sale not taken place, and in any such case appropriate provisions shall be made with respect to the rights and interests of the Holder to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Exercise Price and of the number of shares of Common Stock receivable upon the exercise of this Warrant) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock, securities, other evidence of equity ownership or assets thereafter deliverable upon the exercise hereof (including an immediate adjustment, by reason of such consolidation or merger, of the Exercise Price to the value for the Common Stock reflected by the terms of such consolidation or merger if the value so reflected is less than the Exercise Price in effect immediately prior to such consolidation or merger). Subject to the terms of this Warrant, in the event of a merger or consolidation of the Company with or into another corporation or other entity as a result of which the number of shares of common stock of the surviving corporation or other entity issuable to holders of Common Stock, is greater or lesser than the number of shares of Common Stock outstanding immediately prior to such merger or consolidation, then the Exercise Price in effect immediately prior to such merger or consolidation shall be adjusted in the same manner as though there were a subdivision or combination of the outstanding shares of Common Stock. The Company shall not effect any such consolidation, merger or sale, unless, prior to the consummation thereof, the successor corporation (if other than the Company) resulting from such consolidation or merger or the corporation purchasing such assets shall assume by written instrument executed and mailed or delivered to the Holder, the obligation to deliver to the Holder such shares of stock, securities, other evidence of equity ownership or assets as, in accordance with the foregoing provisions, the Holder may be entitled to receive or otherwise acquire. If a purchase, tender or exchange offer is made to and accepted by the holders of more than fifty (50%) percent of the outstanding shares of Common Stock, the Company shall not effect any consolidation, merger or sale with the person having made such offer or with any affiliate of such person, unless prior to the consummation of such consolidation, merger or sale the Holder of this Warrant shall have been given a reasonable opportunity to then elect to receive upon the exercise of this Warrant the amount of stock, securities, other evidence of equity ownership or assets then issuable with respect to the number of shares of Common Stock in accordance with such offer. 48 (iv) In case the Company shall, at any time prior to exercise of this Warrant, consolidate or merge with any other corporation or other entity (where the Company is not the surviving entity) or transfer all or substantially all of its assets to any other corporation or other entity, then the Company shall, as a condition precedent to such transaction, cause effective provision to be made so that the Holder of this Warrant upon the exercise of this Warrant after the effective date of such transaction shall be entitled to receive the kind and amount of shares, evidences of indebtedness and/or other securities or property receivable on such transaction by a holder of the number of shares of Common Stock as to which this Warrant was exercisable immediately prior to such transaction (without giving effect to any restriction upon such exercise); and, in any such case, appropriate provision shall be made with respect to the rights and interest of the Holder of this Warrant to the end that the provisions of this Warrant shall thereafter be applicable (as nearly as may be practicable) with respect to any shares, evidences of indebtedness or other securities or assets thereafter deliverable upon exercise of this Warrant. Upon the occurrence of any event described in this Section 4(iv), the holder of this Warrant shall have the right to (i) exercise this Warrant immediately prior to such event at an Exercise Price equal to lesser of (1) the then Exercise Price or (2) the price per share of Common Stock paid in such event, or (ii) retain ownership of this Warrant, in which event, appropriate provisions shall be made so that the Warrant shall be exercisable at the Holder's option into shares of stock, securities or other equity ownership of the surviving or acquiring entity. Whenever the Exercise Price shall be adjusted pursuant to this Section 4, the Company shall issue a certificate signed by its President or Vice President and by its Treasurer, Assistant Treasurer, Secretary or Assistant Secretary, setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated (including a description of the basis on which the Board of Directors of the Company made any determination hereunder), and the Exercise Price after giving effect to such adjustment, and shall cause copies of such certificates to be mailed (by first-class mail, postage prepaid) to the Holder of this Warrant. The Company shall make such certificate and mail it to the Holder promptly after each adjustment. No fractional shares of Common Stock shall be issued in connection with any exercise of this Warrant, but in lieu of such fractional shares, the Company shall make a cash payment therefore equal in amount to the product of the applicable fraction multiplied by the Exercise Price then in effect. 5. In the event the Company grants rights (other than rights granted pursuant to a shareholder rights or poison pill plan) to all shareholders to purchase Common Stock, the Holder shall have the same rights as if this Warrant had been exercised immediately prior to such grant. 49 6. The shares of Common Stock issuable upon the exercise of this Warrant shall be registered by the Company pursuant to a Form S-8 to be filed with the Securities and Exchange Commission on or prior to December 2, 2002. 7. This Warrant need not be changed because of any change in the Exercise Price or in the number of shares of Common Stock purchased hereunder. 8. The terms defined in this paragraph, whenever used in this Warrant, shall, unless the context otherwise requires, have the respective meanings hereinafter specified. The term "Common Stock" shall mean and include the Company's Common Stock, $.001 par value per share, authorized on the date of the original issue of this Warrant and shall also include in case of any reorganization, reclassification, consolidation, merger or sale of assets of the character referred to in Section 4 hereof, the stock, securities or assets provided for in such paragraph. The term "Company" shall also include any successor corporation to Calypte Biomedical Corporation by merger, consolidation or otherwise. The term "outstanding" when used with reference to Common Stock shall mean at any date as of which the number of shares thereof is to be determined, all issued shares of Common Stock, except shares then owned or held by or for the account of the Company. The term "1933 Act" shall mean the Securities Act of 1933, as amended, or any successor Federal statute, and the rules and regulations of the Securities and Exchange Commission, or any other Federal agency then administering the 1933 Act, thereunder, all as the same shall be in effect at the time. 9. This Warrant is exchangeable, upon the surrender hereby by the Holder at the office or agency of the Company, for new Warrants of like tenor representing in the aggregate the right to subscribe for and purchase the number of shares of Common Stock which may be subscribed for and purchased hereunder, each of such new Warrants to represent the right to subscribe for and purchase such number of shares of Common Stock as shall be designated by the Holder at the time of such surrender. Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant or any such new Warrants and, in the case of any such loss, theft, or destruction, upon delivery of a bond of indemnity, reasonably satisfactory to the Company, or, in the case of any such mutilation, upon surrender or cancellation of this Warrant or such new Warrants, the Company will issue to the Holder a new Warrant of like tenor, in lieu of this Warrant or such new Warrants, representing the right to subscribe for and purchase the number of shares of Common Stock which may be subscribed for and purchased hereunder. 10. The Company will at no time close its transfer books against the transfer of this Warrant or of any shares of Common Stock issued or issuable upon the exercise of this Warrant in any manner which interferes with the timely exercise of this Warrant. This Warrant shall not entitle the Holder to any voting rights or any rights as a shareholder of the Company. The rights and obligations of the Company, of the Holder, and of any holder of shares of Common Stock issuable hereunder, shall survive the exercise of this Warrant. 50 11. This Warrant sets forth the entire agreement of the Company and the Holder of the Common Stock issuable upon the exercise of this Warrant with respect to the rights of the Holder and the Common Stock issuable upon the exercise of this Warrant, notwithstanding the knowledge of such Holder of any other agreement or the provisions of any agreement, whether or not known to the Holder, and the Company represents that there are no agreements inconsistent with the terms hereof or which purport in any way to bind the Holder of this Warrant or the Common Stock. 12. The validity, interpretation and performance of this Warrant and each of its terms and provisions shall be governed by the laws of the State of California. IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by its duly authorized officer under its corporate seal and dated as of November __, 2002.
