      1.3 ADMINISTRATION.

      1.3.1 Subject to Section 1.3.4, the Plan shall be administered by the
Board or the Committee, whose members shall serve at the pleasure of the Board.
To the extent required for transactions under the Plan to qualify for the
exemptions available under Rule 16b-3 promulgated under the Exchange Act, all
actions relating to Awards to persons subject to Section 16 of the Exchange Act
may be taken by the Board or the Committee composed of two or more members, each
of whom is a "non-employee director" within the meaning of Exchange Act Rule
16b-3. To the extent required for compensation realized from Awards under the
Plan to be deductible by Calypte pursuant to Section 162(m) of the Code, such
Awards may be granted by the Committee composed of two or more members, each of
whom is an "outside director" within the meaning of Code Section 162(m).

      1.3.2 Subject to Section 3.1, the Committee shall have complete control
over the administration of the Plan and shall have the authority in its
discretion to (a) exercise all of the powers granted to it under the Plan, (b)
construe, interpret and implement the Plan and any Award Agreements, (c)
prescribe, amend and rescind rules and regulations relating to the Plan,
including rules governing its own operations, (d) make all determinations
necessary or advisable in administering the Plan, (e) correct any defect, supply
any omission and reconcile any inconsistency in the Plan, (f) amend the Plan to
reflect changes in applicable law, (g) amend any outstanding Award Agreement in
any respect, including, without limitation, to accelerate the time or times at
which the Award becomes vested, unrestricted or may be exercised, waive or amend
any goals, restrictions or conditions set forth in such Award Agreement, or
impose new goals, restrictions and conditions, or reflect a change in the
grantee's circumstances (e.g., a change to part-time employment status), and (h)
determine whether, to what extent and under what circumstances and method or
methods (1) Awards may be (A) settled in cash, shares of Common Stock, other
securities, other Awards or other property, (B) exercised or (C) canceled,
forfeited or suspended, (2) shares of Common Stock, other securities, other
Awards or other property, and other amounts payable with respect to an Award may
be deferred either automatically or at the election of the grantee thereof or of
the Committee, (3) loans (whether or not secured by Common Stock) may be
extended by the Company with respect to any Awards and (4) Awards may be settled
by Calypte, any of its subsidiaries or affiliates or any of its or their
designees.

      1.3.3 Actions of the Committee may be taken by the vote of a majority of
its members. Any action may be taken by a written instrument signed by a
majority of the Committee members, and action so taken shall be fully as
effective as if it had been taken by a vote at a meeting. The determination of
the Committee on all matters relating to the Plan or any Award Agreement shall
be final, binding and conclusive. The Committee may allocate among its members
and delegate to any person who is not a member of the Committee any of its
administrative responsibilities.

      1.3.4 No member of the Board or the Committee or any employee of the
Company shall be liable for any action or determination made in good faith with
respect to the Plan or any Award thereunder. Each such person shall be
indemnified and held harmless by Calypte against and from any loss, cost,
liability, or expense that may be imposed upon or incurred by such person in
connection with or resulting from any action, suit or proceeding to which such
person may be a party or in which such person may be involved by reason of any
action taken or failure act under the Plan or any Award Agreement and against
and from any and all amounts paid by such person, with Calypte's approval, in
settlement thereof, or paid by such person in satisfaction of any judgment in
any such action, suit or proceeding against such person, provided that Calypte
shall have the right, at its own expense, to assume and defend the same. The
foregoing right of indemnification shall not be available to a person to the
extent that a final judgment or other final adjudication binding upon such
person establishes that the acts or omissions of such person giving rise to the
indemnification claim resulted from such person's bad faith, fraud or willful
criminal act or omission. The foregoing right of indemnification shall not be
exclusive of any other rights of indemnification to which such persons may be
entitled under Calypte's Certificate of Incorporation or Bylaws, as a matter of
law, or otherwise, or any other power that Calypte may have to indemnify such
persons or hold them harmless.

1.4   PERSONS ELIGIBLE FOR AWARDS.

      Awards under the Plan may be made to such officers, employees (including
prospective employees), consultants and other individuals who may perform
services for the Company, as the Committee may select.

1.5   TERMINATION OF EMPLOYMENT.

      The Committee may impose on any Award or the exercise or settlement
thereof, at the date of grant or, subject to the provisions of Section 3.1,
thereafter, such additional terms and conditions not inconsistent with the
provisions of the Plan as the Committee shall determine, including terms
requiring forfeiture, acceleration or pro-rata acceleration of Awards in the
event of a Termination of Employment. Except as otherwise determined by the
Committee, all Options that have not been exercised, or any other Awards that
remain subject to a risk of forfeiture or which are not otherwise vested, or
which have outstanding Performance Periods, at the time of a Termination of
Employment shall be forfeited to the Company.

      1.5.2 TERMINATION FOR CAUSE. If a grantee's Employment is terminated for
Cause, then all Options and other Awards that remain subject to a risk of
forfeiture or which are not otherwise vested held by such grantee shall
immediately be terminated and cancelled upon Termination of Employment.

      1.5.3 DEATH, DISABILITY, TERMINATION WITHOUT CAUSE. Except as otherwise
provided in the applicable Award Agreement, upon the grantee's death, Disability
or Termination of Employment for any reason other than for Cause, the grantee:

            1.5.3.1 shall forfeit all Awards that have not previously vested or
      remain subject to a risk of forfeiture;

            1.5.3.2 shall have thirty (30) days to exercise the grantee's Awards
      that are vested on the Termination of Employment if such termination is
      for any reason other than the grantee's Disability or death; and

            1.5.3.3 shall have one (1) year to exercise the grantee's Awards
      that are vested on the date of Disability or death if the grantee's
      Termination of Employment is due to the grantee's Disability or death.

      1.5.4 TERMINATION AFTER CHANGE IN CONTROL. Except as otherwise provided by
the Committee or in the applicable Award Agreement, if any grantee's Employment
is terminated by the Company for any reason other than for Cause within six (6)
months after a "change in control" as defined in Section 3.7, then all unvested
Awards and other Awards remaining subject to a risk of forfeiture held by such
grantee shall become fully vested for exercise upon the Termination of
Employment.

      1.5.5 Any Awards not exercised within the permissible period of time shall
be forfeited by the grantee. Notwithstanding any of the foregoing, the grantee
shall not be permitted to exercise any Option at a time beyond the initial
option term.

1.6   TYPES OF AWARDS UNDER PLAN.

      Awards may be made under the Plan in the form of (a) Options, (b) stock
appreciation rights, (c) dividend equivalent rights, (d) restricted stock, (e)
restricted stock units, (f) other equity-based or equity-related Awards which
the Committee determines to be consistent with the purpose of the Plan and the
interests of the Company, and (g) Incentive Awards. No Incentive Stock Option
(other than an Incentive Stock Option that may be assumed or issued by Calypte
in connection with a transaction to which Section 424(a) of the Code applies)
may be granted to a person who is not eligible to receive an Incentive Stock
Option under the Code.

1.7   SHARES AVAILABLE FOR AWARDS.

      1.7.1 TOTAL SHARES AVAILABLE. Subject to adjustment pursuant to Section
1.7.2, the total number of shares of Common Stock which may be delivered
pursuant to Awards granted under the Plan shall be 30,000,000, of which
8,000,000 shall be available for delivery as restricted stock and restricted
stock units. If, after the effective date of the Plan, any Award is forfeited or
otherwise terminated or canceled without the delivery of shares of Common Stock
or is settled for cash, any shares of Common Stock are surrendered or withheld
from any Award to satisfy a grantee's income tax or other withholding
obligations, or any shares of Common Stock owned by a grantee are tendered to
pay the exercise price of any Award granted under the Plan, then the shares
covered by such forfeited, terminated or canceled Award or which are equal to
the number of shares settled, surrendered, withheld or tendered shall again
become available for transfer pursuant to Awards granted or to be granted under
this Plan.

      1.7.2 ADJUSTMENTS. The Committee shall adjust the number of shares of
Common Stock authorized pursuant to Section 1.7.1 and adjust (including, without
limitation, by payment of cash) the terms of any outstanding Awards (including,
without limitation, the number of shares of Common Stock covered by each
outstanding Award, the type of property to which the Award is subject and the
exercise or strike price of any Award), in such manner as necessary to preserve
the benefits or potential benefits intended to be made available to grantees of
Awards, for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
spinoff, splitup, combination or reclassification of the Common Stock, or any
other event the Committee determines in its sole discretion affects the
capitalization of Calypte, including any extraordinary dividend or distribution.
After any adjustment made pursuant to this Section 1.7, the number of shares of
Common Stock subject to each outstanding Award shall be rounded to the nearest
whole number.

      1.7.3 MAXIMUM AWARDS. Subject to adjustment as provided in Section 1.7.2,
(a) the maximum number of shares of Common Stock with respect to which Options
or stock appreciation rights may be granted to an individual grantee during any
calendar year shall equal 8,000,000 shares of Common Stock, (b) the maximum
number of shares of Common Stock with respect to which restricted stock or
restricted stock units may be granted to an individual grantee during any
calendar year shall equal 8,000,000 shares of Common Stock, (c) the total value
of any Incentive Award awarded to an individual grantee during any calendar year
shall not exceed $1,000,000. Any shares of Common Stock (a) delivered by
Calypte, (b) with respect to which Awards are made by Calypte and (c) with
respect to which Calypte becomes obligated to make Awards, in each case through
the assumption of, or in substitution for, outstanding awards previously granted
by an acquired entity, shall not be counted against the shares of Common Stock
available for Awards under this Plan. Shares of Common Stock which may be
delivered pursuant to Awards may be authorized but unissued Common Stock or
authorized and issued Common Stock held in Calypte's treasury or otherwise
acquired for the purposes of the Plan.

                                   ARTICLE II
                              AWARDS UNDER THE PLAN

2.1   AGREEMENTS EVIDENCING AWARDS.

      Each Award granted under the Plan shall be evidenced by a written document
which shall contain such provisions and conditions as the Committee deems
appropriate. The Committee may grant Awards in tandem with or in substitution
for any other Award or Awards granted under this Plan or any award granted under
any other plan of the Company. By accepting an Award pursuant to the Plan, a
grantee thereby agrees that the Award shall be subject to all of the terms and
provisions of the Plan and the applicable Award Agreement.

2.2   NO RIGHTS AS A SHAREHOLDER.

      No grantee of an Award shall have any of the rights of a shareholder of
Calypte with respect to shares subject to such Award until the delivery of such
shares. Except as otherwise provided in Section 1.7.2, no adjustments shall be
made for dividends, distributions or other rights (whether ordinary or
extraordinary, and whether in cash, Common Stock, other securities or other
property) for which the record date is prior to the date such shares are
delivered.

2.3   GRANT OF OPTIONS.

The Committee may grant Options to purchase shares of Common Stock from Calypte,
in such amounts and subject to such terms and conditions as the Committee may
determine. The price of an Option under this Plan shall be determined in the
sole discretion of the Committee; provided, however, if the Committee designates
an Option as an Incentive Stock Option, then such Option shall be granted only
to an employee of the Company, shall have a per share price not less than 100%
of the Fair Market Value of a share of Common Stock on the date of grant of the
Option, and, if granted to a person who owns capital stock (including stock
treated as owned under Section 424(d) of the Code) possessing more than 10% of
the total combined voting power of all classes of capital stock of the Company
(a "10% Owner"), have a per share price not less than 110% of the Fair Market
Value of a share of Common Stock on the date of grant, and shall be for a period
of not more than 10 years (five years if the Grantee is a 10% Owner) from the
date of grant. Notwithstanding designation as an Incentive Stock Option, if the
shares of Common Stock subject to a grantee's Incentive Stock Options (granted
under all plans of the Company), which become exercisable for the first time
during any calendar year, have a Fair Market Value in excess of $100,000, the
Options accounting for the excess will be treated as Nonqualified Stock Options.
Incentive Stock Options will be taken into account in the order in which they
were granted, and the Fair Market Value of the shares of Common Stock will be
determined as of the date of grant.

2.4   STOCK APPRECIATION RIGHTS.

      The Committee may grant Stock Appreciation Rights in conjunction with all
or part of an Option granted under the Plan. In the case of a Nonqualified Stock
Option, such rights may be granted either at or after the date of grant of such
Option. In the case of an Incentive Stock Option, such rights may be granted
only at the date of grant of such Option. A Stock Appreciation Right shall
terminate and no longer be exercisable upon the termination or exercise of the
related Option. In either case, the terms and conditions of a Stock Appreciation
Right shall be set forth in the Award Agreement for the related Option or an
amendment thereto. Stock Appreciation Rights shall be exercisable only at such
time or times and to the extent that the Options to which they relate. Upon
exercise of a Stock Appreciation Right, a grantee shall be entitled to receive
an amount equal to the product of (a) the excess of the Fair Market Value of one
share of Common Stock over the exercise price per share specified in the related
Option times (b) the number of shares in respect of which the Stock Appreciation
Right shall have been exercised, in cash, shares of Common Stock or both, with
the Committee having the right to determine the form of payment.

2.5   EXERCISE OF OPTIONS AND STOCK APPRECIATION RIGHTS.

      2.5.1 Any acceptance by the Committee of a grantee's written notice of
exercise of an Option shall be conditioned upon payment for the shares being
purchased. Such payment may be made in cash or by such other method as the
Committee may from time to time prescribe.

      2.5.2 After receiving payment from the grantee of the full Option exercise
price, or after receiving notice from the grantee of the exercise of a stock
appreciation right for which payment will be made by Calypte partly or entirely
in shares of Common Stock, Calypte shall, subject to the provisions of the Plan
or any Award Agreement, deliver the shares of Common Stock.

2.6   GRANT OF DIVIDEND EQUIVALENT RIGHTS.

      The Committee may include in the Award Agreement with respect to any Award
a dividend equivalent right entitling the grantee to receive amounts equal to
all or any portion of the dividends that would be paid on the shares of Common
Stock covered by such Award if such shares had been delivered pursuant to such
Award. The grantee of a dividend equivalent right will have only the rights of a
general unsecured creditor of Calypte until payment of such amounts is made as
specified in the applicable Award Agreement. In the event such a provision is
included in an Award Agreement, the Committee shall determine whether such
payments shall be made in cash, in shares of Common Stock or in another form,
whether they shall be conditioned upon the exercise of the Award to which they
relate, the time or times at which they shall be made, and such other terms and
conditions as the Committee shall deem appropriate.

2.7   GRANT OF RESTRICTED STOCK.

      The Committee may grant or offer for sale restricted shares of Common
Stock in such amounts and subject to such terms and conditions as the Committee
shall determine, including restrictions based upon the achievement of
Performance Goals, time-based restrictions on vesting following the attainment
of the Performance Goals; provided, that such restrictions may lapse, if so
determined by the Committee, in the event of the Grantee's Termination of
Employment due to death, Disability or Termination of Employment by the Company
without Cause. Upon the delivery of restricted shares of Common Stock, the
grantee shall have the rights of a shareholder with respect to the restricted
stock, subject to any restrictions and conditions as the Committee may include
in the applicable Award Agreement. In the event that a Certificate is issued in
respect of restricted shares of Common Stock, such Certificate may be registered
in the name of the grantee but shall be held by Calypte or its designated agent
until the time the restrictions lapse.

2.8   GRANT OF RESTRICTED STOCK UNITS.

      The Committee may grant Awards of restricted stock units in such amounts
and subject to such terms and conditions as the Committee shall determine. A
grantee of a restricted stock unit will have only the rights of a general
unsecured creditor of Calypte until delivery of shares of Common Stock or cash
is made as specified in the applicable Award Agreement. On the delivery date,
the grantee of each restricted stock unit not previously forfeited shall receive
one share of Common Stock or cash equal in value to a share of Common Stock or a
combination thereof, as specified by the Committee.

2.9   GRANT OF OTHER STOCK-BASED AWARDS.

      The Committee may grant other types of equity-based or equity-related
Awards (including the grant or offer for sale of unrestricted shares of Common
Stock) in such amounts and subject to such terms and conditions as the Committee
shall determine. Such Awards may entail the transfer of actual shares of Common
Stock to Plan participants, or payment in cash or otherwise of amounts based on
the value of shares of Common Stock.

2.10  GRANT OF INCENTIVE AWARDS.

      The Committee may grant Incentive Awards in such amounts and subject to
the achievement of Performance Goals during Performance Periods and other terms
and conditions as the Committee shall determine. Incentive Awards shall be
granted and administered to comply with the requirements of Section 162(m) of
the Code. After the applicable Performance Period has ended, the grantee shall
be entitled to payment based on the level of achievement of the Performance
Goals set by the Committee. The Committee shall certify the achievement of the
Performance Goals in writing before the Incentive Award is settled. At the
discretion of the Committee, the settlement of Incentive Awards may be in cash,
shares of Common Stock, or in some combination thereof, as set forth in the
Award Agreement. If a grantee is promoted or demoted during a Performance
Period, then, to the extent the Committee determines that the Award, the
Performance Goals or the Performance Period are no longer appropriate, the
Committee may adjust, change, eliminate or cancel the Award, the Performance
Goals or the applicable Performance Period, as it deems appropriate in order to
make them appropriate and comparable to the initial Award, the Performance Goals
or the Performance Period.

2.11  TAX OFFSET BONUSES.

      At the time an Award is made hereunder or at any time thereafter, the
Committee may grant to the grantee receiving such Award the right to receive a
cash payment in an amount specified by the Committee, to be paid at such time or
times (if ever) as the Award results in compensation income to the grantee, for
the purpose of assisting the grantee to pay the resulting taxes, all as
determined by the Committee, and on such other terms and conditions as the
Committee shall determine.

                                  MISCELLANEOUS

3.1   AMENDMENT OF THE PLAN.

      3.1.1 The Board may from time to time alter, suspend, discontinue, revise,
amend or terminate the Plan in any respect whatsoever, provided, that no
termination, amendment, or modification of the Plan shall adversely affect in
any material way any Award previously granted under the Plan, without the
written consent of the grantee of such Award, except as otherwise specifically
permitted in the Plan or such Award Agreement.

      3.1.2 Unless otherwise determined by the Board, shareholder approval of
any suspension, discontinuance, revision or amendment shall be obtained only to
the extent necessary to comply with any applicable law, rule or regulation or
stock exchange requirement.

3.2   TAX WITHHOLDING.

      3.2.1 As a condition to the delivery of any shares of Common Stock
pursuant to any Award or the lifting or lapse of restrictions on any Award, or
in connection with any other event that gives rise to a federal or other
governmental tax withholding obligation on the part of Calypte or any of its
subsidiaries or affiliates relating to an Award (including, without limitation,
FICA tax), (a) Calypte may deduct or withhold (or cause to be deducted or
withheld) from any payment or distribution to a grantee whether or not pursuant
to the Plan or (b) the Committee shall be entitled to require that the grantee
remit cash to Calypte or any of its subsidiaries or affiliates (through payroll
deduction or otherwise), in each case in an amount sufficient in the opinion of
Calypte to satisfy such withholding obligation.

      3.2.2 If the event giving rise to the withholding obligation involves a
transfer of shares of Common Stock, then, unless the applicable Award Agreement
provides otherwise, at the discretion of the Committee, the grantee may satisfy
the withholding obligation described under Section 3.2.1 by electing to have
Calypte withhold shares of Common Stock (which withholding will be at a rate not
in excess of the statutory minimum rate) or by tendering previously owned shares
of Common Stock, in each case having a Fair Market Value equal to the amount of
tax to be withheld (or by any other mechanism as may be required or appropriate
to conform with local tax and other rules). For this purpose, Fair Market Value
shall be determined as of the date on which the amount of tax to be withheld is
determined (and Calypte may cause any fractional share amount to be settled in
cash).

3.3   REQUIRED CONSENTS AND LEGENDS.

      3.3.1 If the Committee shall at any time determine that any consent (as
hereinafter defined) is necessary or desirable as a condition of, or in
connection with, the granting of any Award, the delivery of shares of Common
Stock or the delivery of any cash, securities or other property under the Plan,
or the taking of any other action thereunder (each such action being hereinafter
referred to as a "plan action"), then such plan action shall not be taken, in
whole or in part, unless and until such consent shall have been effected or
obtained to the full satisfaction of the Committee. The Committee may direct
that any Certificate evidencing shares delivered pursuant to the Plan shall bear
a legend setting forth such restrictions on transferability as the Committee may
determine to be necessary or desirable, and may advise the transfer agent to
place a stop order against any legended shares.

3.3.2 The term "consent" as used herein with respect to any plan action includes
(a) any and all listings, registrations or qualifications in respect thereof
upon any securities exchange or under any federal, state, or local law, or law,
rule or regulation of a jurisdiction outside the United States, (b) any and all
written agreements and representations by the grantee with respect to the
disposition of shares, or with respect to any other matter, which the Committee
may deem necessary or desirable to comply with the terms of any such listing,
registration or qualification or to obtain an exemption from the requirement
that any such listing, qualification or registration be made, (c) any and all
other consents, clearances and approvals in respect of a plan action by any
governmental or other regulatory body or any stock exchange or self-regulatory
agency and (d) any and all consents or authorizations required to comply with,
or required to be obtained under, applicable local law or otherwise required by
the Committee. Nothing herein shall require Calypte to list, register or qualify
the shares of Common Stock on any securities exchange.

3.4   NONASSIGNABILITY.

      Except to the extent otherwise expressly provided in the applicable Award
Agreement, no Award (or any rights and obligations thereunder) granted to any
person under the Plan may be sold, exchanged, transferred, assigned, pledged,
hypothecated or otherwise disposed of (including through the use of any
cash-settled instrument) (each such action being hereinafter referred to as an
"assignment"), whether voluntarily or involuntarily, other than by will or by
the laws of descent and distribution, and all such Awards (and any rights
thereunder) shall be exercisable during the life of the grantee only by the
grantee or the grantee's legal representative. Notwithstanding the immediately
preceding sentence, the Committee may permit, under such terms and conditions
that it deems appropriate in its sole discretion, a grantee to transfer any
Award to any person or entity that the Committee so determines. Any assignment
in violation of the provisions of this Section 3.4 shall be void. All of the
terms and conditions of this Plan and the Award Agreements shall be binding upon
any such permitted successors and assigns.

3.5   REQUIREMENT OF CONSENT AND NOTIFICATION OF ELECTION UNDER SECTION 83(B) OF
      THE CODE OR SIMILAR PROVISION.

      No election under Section 83(b) of the Code (to include in gross income in
the year of transfer the amounts specified in Code Section 83(b)) or under a
similar provision of the law of a jurisdiction outside the United States may be
made unless expressly permitted by the terms of the Award Agreement or by action
of the Committee in writing prior to the making of such election. If a grantee
of an Award, in connection with the acquisition of shares of Common Stock under
the Plan or otherwise, is expressly permitted under the terms of the Award
Agreement or by such Committee action to make any such election and the grantee
makes the election, the grantee shall notify the Committee of such election
within ten (10) days of filing notice of the election with the Internal Revenue
Service or other governmental authority, in addition to any filing and
notification required pursuant to regulations issued under Code Section 83(b) or
other applicable provision.

3.6   REQUIREMENT OF NOTIFICATION UPON DISQUALIFYING DISPOSITION UNDER SECTION
      421(B) OF THE CODE.


      If any grantee shall make any disposition of shares of Common Stock
delivered pursuant to the exercise of an Incentive Stock Option under the
circumstances described in Section 421(b) of the Code (relating to certain
disqualifying dispositions), such grantee shall notify Calypte of such
disposition within 10 days thereof.

3.7   CHANGE IN CONTROL.

      3.7.1 The Committee may provide in any Award Agreement for provisions
relating to a "change in control" of Calypte (as such term is defined by the
Committee in any such Award Agreement), including, without limitation, the
acceleration or extension of the exercisability of, or the lapse of restrictions
or deemed satisfaction of goals with respect to, any outstanding Awards.

      3.7.2 Unless otherwise provided in the applicable Award Agreement, in the
event of a merger, consolidation, mandatory share exchange or other similar
business combination of Calypte with or into any other entity ("successor
entity") or any transaction in which another person or entity acquires all of
the issued and outstanding Common Stock of Calypte, or all or substantially all
of the assets of Calypte, outstanding Awards may be assumed or an equivalent
Award may be substituted by such successor entity or a parent or subsidiary of
such successor entity.

3.8   RIGHT OF DISCHARGE RESERVED.

      Nothing in the Plan or in any Award Agreement shall confer upon any
grantee the right to continued Employment by the Company or affect any right
which the Company may have to terminate such Employment.

3.9   NATURE OF PAYMENTS.

      3.9.1 Any and all grants of Awards and deliveries of Common Stock, cash,
securities or other property under the Plan shall be in consideration of
services performed or to be performed for the Company by the grantee. Awards
under the Plan may, in the discretion of the Committee, be made in substitution
in whole or in part for cash or other compensation otherwise payable to an
Employee.

      3.9.2 All such grants and deliveries shall constitute a special
discretionary incentive payment to the grantee and shall not be required to be
taken into account in computing the amount of salary or compensation of the
grantee for the purpose of determining any contributions to or any benefits
under any pension, retirement, profit-sharing, bonus, life insurance, severance
or other benefit plan of the Company or under any agreement with the grantee,
unless the Company specifically provides otherwise.

3.10  NON-UNIFORM DETERMINATIONS.

      The Committee's determinations under the Plan and Award Agreements need
not be uniform and may be made by it selectively among persons who receive, or
are eligible to receive, Awards under the Plan (whether or not such persons are
similarly situated). Without limiting the generality of the foregoing, the
Committee shall be entitled, among other things, to make non-uniform and
selective determinations under Award Agreements, and to enter into non-uniform
and selective Award Agreements, as to (a) the persons to receive Awards, (b) the
terms and provisions of Awards and (c) whether a grantee's Employment has been
terminated for purposes of the Plan.

3.11  OTHER PAYMENTS OR AWARDS.

      Nothing contained in the Plan shall be deemed in any way to limit or
restrict Calypte from making any award or payment to any person under any other
plan, arrangement or understanding, whether now existing or hereafter in effect.

3.12  PLAN HEADINGS.

      The headings in this Plan are for the purpose of convenience only and are
not intended to define or limit the construction of the provisions hereof.

3.13  DATE OF ADOPTION AND TERM OF PLAN.

The Plan was adopted by the Board on February 24, 2004, and made effective as of
June 22, 2004, the date of its approval by the Company's stockholders. Unless
sooner terminated by the Board, the Plan shall terminate on the day before the
tenth anniversary of the effective date of the Plan. The Board reserves the
right to terminate the Plan at any time; provided, however, that all Awards made
under the Plan prior to its termination shall remain in effect until such Awards
have been satisfied or terminated in accordance with the terms and provisions of
the Plan and the applicable Award Agreements.

3.14  GOVERNING LAW.

      ALL RIGHTS AND OBLIGATIONS UNDER THE PLAN AND EACH AWARD AGREEMENT SHALL
BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
DELAWARE, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS.

3.15  SEVERABILITY; ENTIRE AGREEMENT.

      If any of the provisions of this Plan or any Award Agreement is finally
held to be invalid, illegal or unenforceable (whether in whole or in part), such
provision shall be deemed modified to the extent, but only to the extent, of
such invalidity, illegality or unenforceability and the remaining provisions
shall not be affected thereby; provided, that if any of such provisions is
finally held to be invalid, illegal, or unenforceable because it exceeds the
maximum scope determined to be acceptable to permit such provision to be
enforceable, such provision shall be deemed to be modified to the minimum extent
necessary to modify such scope in order to make such provision enforceable
hereunder. The Plan and any Award Agreements contain the entire agreement of the
parties with respect to the subject matter thereof and supersede all prior
agreements, promises, covenants, arrangements, communications, representations
and warranties between them, whether written or oral with respect to the subject
matter thereof.

3.16  WAIVER OF CLAIMS.

      Each grantee of an Award recognizes and agrees that prior to being
selected by the Committee to receive an Award he or she has no right to any
benefits hereunder. Accordingly, in consideration of the grantee's receipt of
any Award hereunder, he or she expressly waives any right to contest the amount
of any Award, the terms of any Award Agreement, any determination, action or
omission hereunder or under any Award Agreement by the Committee, Calypte, or
the Board, or any amendment to the Plan or any Award Agreement (other than an
amendment to this Plan or an Award Agreement to which his or her consent is
expressly required by the express terms of an Award Agreement).

3.17  NO THIRD PARTY BENEFICIARIES.

      Except as expressly provided therein, neither the Plan nor any Award
Agreement shall confer on any person other than the Company and the grantee of
any Award any rights or remedies thereunder.

3.18  SUCCESSORS AND ASSIGNS OF CALYPTE.

      The terms of this Plan shall be binding upon and inure to the benefit of
Calypte and its successors and assigns.
