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. 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 1933:


                                       4


         (ii) To reflect in the prospectus any facts or events arising after the
effective date of this 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 this Registration Statement:

           (iii) To include any material information with respect to the plan of
distribution not previously disclosed in this Registration Statement or any
material change to such information in this Registration Statement; provided,
however, that paragraph (1)(i) and (1)(ii) do not apply if the information
required to be included in a post-effective amendment by those paragraph is
contained in periodic reports filed by the Company pursuant to Section 13 or
Section 15 (d) of the Exchange Act that are incorporated by reference in this
Registration Statement.

     (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.

     Consultant for the Company and contains all the covenants and agreements
     between the parties with respect to the rendering of such services in any
     manner whatsoever. Each party to this agreement acknowledges that no

     Agreement will be the property of the Consultant, subject to the
     irrevocable right and license of the Company to make, use or sell products

               material in the Consultant's possession relating to the Company's
               business.

               14. The obligations regarding Proprietary Information extend to

               about which the Consultant may have gained knowledge as a result
               of performing services hereunder.

               15. The Consultant shall not, during the term of this agreement
               and for a period of one year immediately after the termination of
               this agreement, or any extension of it, either directly or
               indirectly (a) for purposes competitive with the products or
               services currently offered by the Company, call on, solicit, or
               take away any of the Company's customers or potential customers
               about whom the Consultant became aware as a result of the
               Consultant's services to the Company hereunder, either for the
               Consultant or for any other person or entity, or (b) solicit or
               take away or attempt to solicit or take away any of the Company's
               employees or consultants either for the Consultant or for any
               other person or entity.

                          Common Stock Purchase Warrant
                                       to
                         Purchase ______________ Shares
                                       of
                                  Common Stock

                This Common Stock Purchase Warrant is issued to:

                                     [Name]
                                    [Address]
                                [City, State Zip]

by CALYPTE BIOMEDICAL CORPORATION, a Delaware corporation (hereinafter called
the "Company", which term shall include its successors and assigns).

           FOR VALUE RECEIVED and subject to the terms and conditions
hereinafter set out, the registered holder of this Warrant as set forth on the
books and records of the Company (the "Holder") is entitled upon surrender of
this Warrant to purchase from the Company _____________ fully paid and
non-assessable shares of Common Stock, $.001 par value per share (the "Common
Stock"), at the Exercise Price (as defined below) per share.

           This Warrant shall expire at the close of business on _____________,
2003.


                                       45


     1. (a) The right to purchase shares of Common Stock represented by this
Warrant may be exercised by the Holder, in whole or in part, by the surrender of
this Warrant (properly endorsed if required) at the principal office of the
Company at 1265 Harbor Parkway, Alameda, California 94502 (or such other office
or agency of the Company as it may designate by notice in writing to the Holder
at the address of the Holder appearing on the books of the Company), and upon
payment to the Company, by cash or by certified check or bank draft, of the
Exercise Price for such shares. The Company agrees that the shares of Common
Stock so purchased shall be deemed to be issued to the Holder as the record
owner of such shares of Common Stock as of the close of business on the date on
which this Warrant shall have been surrendered and payment made for such shares
of Common Stock as aforesaid. Certificates for the shares of Common Stock so
purchased (together with a cash adjustment in lieu of any fraction of a share)
shall be delivered to the Holder within a reasonable time, not exceeding five
(5) business days, after the rights represented by this Warrant shall have been
so exercised, and, unless this Warrant has expired, a new Warrant representing
the number of shares of Common Stock, if any, with respect to which this Warrant
shall not then have been exercised, in all other respects identical with this
Warrant, shall also be issued and delivered to the Holder within such time, or,
at the request of the Holder, appropriate notation may be made on this Warrant
and the same returned to the Holder.

           (b) This Warrant may be exercised to acquire, from and after the date
hereof, the number of shares of Common Stock set forth on the first page hereof
(subject to adjustments described in this Warrant); provided, however, the right
hereunder to purchase such shares of Common Stock shall expire at 5:00 p.m.
Alameda, California time on _____________, 2003.

     2. This Warrant is being issued by the Company pursuant to the terms of the
Consulting Agreement dated ______________, 2002.

     3. The Company covenants and agrees that all Common Stock upon issuance
against payment in full of the Exercise Price by the Holder pursuant to this
Warrant will be validly issued, fully paid and non-assessable and free from all
taxes, liens and charges with respect to the issue thereof (except to the extent
resulting from the Holder's own circumstances, actions or omissions). The
Company covenants and agrees that during the period within which the rights
represented by this Warrant may be exercised, the Company will have at all times
authorized, and reserved for the purpose of issue or transfer upon exercise of
the rights evidenced by this Warrant, a sufficient number of shares of Common
Stock to provide for the exercise of the rights represented by this Warrant, and
will procure at its sole expense upon each such reservation of shares the
listing thereof (subject to issuance or notice of issuance) on all stock
exchanges on which the Common Stock is then listed or inter-dealer trading
systems on which the Common Stock is then traded. The Company will take all such
action as may be necessary to assure that such shares of Common Stock may be so
issued without violation of any applicable law or regulation, or of any
requirements of any national securities exchange upon which the Common Stock may
be listed or inter-dealer trading system on which the Common Stock is then
traded. 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.

Calypte Biomedical Corporation

Re:        Opinion of Counsel - Registration Statement on Form S-8

Gentleman:

           I have acted as counsel for Calypte Biomedical Corporation (the
"Company"), in connection with the preparation and filing of the Company's
Registration statement on Form S-8 under the Securities Act of 1933, as amended,
(the "Registration Statement"), relating to 30,550,000 shares of the Company's
common stock, $.001 par value, (the "common stock"), issuable pursuant to the
Company's Advisory and Consultants Agreements, (the "Plan").

           I have examined the Certificate of Incorporation, as amended, and the
By-Laws of the company and all amendments thereto, the Registration Statement
and originals, or copies certified to my satisfaction, of such records and
meetings, written actions in lieu of meetings, or resolutions adopted at
meetings, of the directors of the Company, and such other documents and
instruments as in my judgement are necessary or appropriate to enable me to
render the opinions expressed below.

           Based on the foregoing examination, I am of the opinion that the
shares of Common Stock issuable with the Plan are duly authorized and, when
issued in accordance with the Plan, will be validly issued, fully paid and
non-assessable.

           Further, I consent to the filing of this opinion as an exhibit to the
Registration Statement.

                     Very truly yours,

                     /s/ Owen Naccarato
                     ____________________
                     Owen Naccarato, Esq.

                    CONSENT OF KPMG LLP, INDEPENDENT AUDITORS

The Board of Directors
Calypte Biomedical Corporation:

We consent to the use of our report incorporated by reference herein.

Our report dated February 8, 2002 contains an explanatory paragraph that states
that the Company has suffered recurring losses from operations and has an
accumulated deficit that raise substantial doubt about its ability to continue
as a going concern. The consolidated financial statements do not include any
adjustments that might result from the outcome of this uncertainty.
