ITEM 24.   INDEMNIFICATION OF DIRECTORS AND OFFICERS

Section 145 of the Delaware  General  Corporation  Law permits a corporation  to
include in its charter documents,  and in agreements between the corporation and
its directors and officers,  provisions  expanding the scope of  indemnification
beyond that specifically provided by the current law.

Article VIII of the Registrant's  Certificate of Incorporation  provides for the
indemnification  of directors to the fullest extent  permissible  under Delaware
law.

Article  VI of the  Registrant's  Bylaws  provides  for the  indemnification  of
officers,  directors and third parties  acting on behalf of the  corporation  if
such person acted in good faith and in a manner reasonably believed to be in and
not opposed to the best  interest of the  corporation,  and, with respect to any
criminal action or proceeding,  the  indemnified  party had no reason to believe
his conduct was unlawful.

Calypte has entered  into  indemnification  agreements  with its  directors  and
executive  officers,  in addition to  indemnification  provided for in Calypte's
Bylaws,  and  intends  to enter  into  indemnification  agreements  with any new
directors and executive officers in the future.

ITEM 26.    RECENT SALES OF UNREGISTERED SECURITIES`

Private Placements of Common Stock

On January 22, 2001, the Company signed an agreement to place up to $1.1 million
in convertible short-term debentures. Under this arrangement, the Company issued
two convertible  debentures to the debenture  holders in the principal amount of
$550,000,  pursuant to Regulation S of the Securities Act. Each debenture had an
interest rate of 6% and was issued at an original  issue  discount of 9.1%.  The
Company  issued the first  debenture on January 26, 2001 and the second on March
13, 2001. Each debenture matured 90 days from the date of issuance,  or on April
26, 2001 and June 11, 2001, respectively. Under the terms of the debentures, the
debenture  holder  could  elect at any time prior to  maturity  to  convert  the
balance  outstanding on the debentures into shares of the Company's common stock
at a fixed price that  represented a 5% discount to the average trading price of
the shares for the 10 trading days preceding the issuance of each debenture.  If
the Company chose not to redeem the debentures upon maturity,  as in the case of
the second debenture,  the conversion discount to the debenture holder increased
to 15% of the average low bid price for the Company's common stock for any three
of the 22 trading  days  prior to the date of  conversion.  Concurrent  with the
issuance  of the first  debenture,  the  Company  also  issued a warrant  to the
debenture  holder for 6,667 shares of common stock at an exercise  price of $45.
The shares  underlying the debentures and warrant were  registered  using a Form
S-3 Registration Statement. The Company received aggregate net proceeds from the
issuance of the two debentures of $925,000 during the first quarter of 2001.


                                      II-1



On January 24, 2001, the Company amended a common stock purchase  agreement with
a private investment fund for the issuance and purchase of its common stock. The
initial  closing of the  transaction  took place on November 2, 2000.  The stock
purchase agreement established what is sometimes termed an equity line of credit
or an equity  draw down  facility.  The  facility  generally  operated  with the
investor  committed to purchase up to $25 million or up to 20% of the  Company's
outstanding shares of common stock over a twelve-month  period. Once during each
draw down pricing period, the Company could request a draw, subject to a formula
based on the Company's  average stock price and average  trading  volume setting
the maximum  amount of the request for any given draw.  The amount of money that
the investor provided to the Company and the number of shares the Company issued
to the  investor  in return for that money was  settled  during a 22 day trading
period  following  the draw  down  request  based on the  formula  in the  stock
purchase agreement.  The investor received a 5% discount to the market price for
the 22 day period and the Company  received the settled amount of the draw down.
By June 30, 2001, the Company had issued 169,500 shares of its common stock, the
total number  registered  for the equity line with the  Securities  and Exchange
Commission,  at an  average  price of  $12.60  per share  and had  received  net
proceeds  of   approximately   $2,014,000   after  deducting   expenses  of  the
transaction.  There are no further  funds  available  to the Company  under this
equity line.

In August 2001,  the Company and the same private  investment  fund mentioned in
the preceding  paragraph signed a common stock purchase agreement for the future
issuance and purchase of up to $10 million of the Company's  common stock over a
twenty-four  month period.  The initial closing of the  transaction  occurred in
October 2001. Under this arrangement, the Company, at its sole discretion, could
draw down on this facility,  sometimes termed an equity line, from time to time,
and the investment fund was obligated to purchase shares of the Company's common
stock.  The purchase  price of the common stock  purchased  pursuant to any draw
down  was  equal  to 88% of the  daily  volume  weighted  average  price  of the
Company's  common stock on the applicable  date. In conjunction with the signing
of the stock  purchase  agreement,  in October 2001, the Company issued a 7-year
fully-vested  warrant to the investment fund to purchase up to 139,742 shares of
common  stock at an  exercise  price of $8.23 per share and 3,833  shares of its
common stock as additional fees to the investment fund. The private placement of
the related warrants was exempt from registration pursuant to Regulation S. From
the time the  Registration  statement  became effective in November 2001 through
the  expiration of the facility in October 2003,  the Company  issued a total of
855,776  shares of its common  stock at an average  price of $3.93 per share and
received proceeds of approximately  $3.2 million after deducting expenses of the
transactions.  At the time the facility expired,  633 registered shares remained
available for sale under this facility.

In  November  2001,  the  Company  sold  52,528  shares  of common  stock  under
Regulation D of the  Securities  Act of 1933 ("the  Securities  Act") to various
investors in a private  placement at $5.70 per share,  receiving net proceeds of
$295,000. The private placement did not include registration rights.  Therefore,
pursuant to Rule 144 of the  Securities  Act,  the  transfer  of the  securities
purchased by the  investors  was  restricted  for twelve months from the date of
purchase. Three former members of the Company's Board of Directors,  Nancy Katz,
Mark Novitch and David Collins,  purchased an aggregate of 24,038 shares of this
offering.  The proceeds of this offering were used to fund the Company's current
operations.  The purchase  transactions by the Company's Board members were on a
fair and reasonable  basis and on terms more favorable to the Company than could
have been  obtained  with  non-affiliated  parties  as a result  of the  tenuous
financial condition of the Company at the time.


The following table summarizes the Company's  financing  activities from January
2002  through  December  16, 2004 by major  category  and the  subsequent  table
provides the details of these financings.  All amounts are in thousands,  except
per share closing  prices in the second  table.  All share amounts and per share
prices reflect the post-split  basis of the 1:30 reverse stock split approved by
our  stockholders  on May 20, 2003 and which became  effective on May 28, 2003.)
The  proceeds of all of these  financings  have been used to fund the  Company's
current operations.

        (1)  At December 16, 2004, the holders have converted all but $60,000 of
             principal of the  convertible  debentures  issued  since  September
             2002. Based on current market prices,  we estimate that we would be
             required to issue  approximately  0.4 million  additional shares of
             our common  stock if the holders  elected to convert the  remaining
             principal  and accrued  interest of their  debentures at this time.
             The holders of these 12% convertible debentures claim a transaction
             date which we dispute. These debentures have not yet been converted
             pending  resolution  of the  transaction  date  dispute,  which may
             impact  the  number of  shares of our stock to which the  holder is
             entitled upon conversion. See Note 12 to Detail of Financings.

                                      II-7



- ---------------------

       (1) The Bristol  Debentures and Warrants,  the 8% Convertible  Notes, the
Other Restart Financings,  the Mercator 12% and 10% Debentures and warrants, and
ther Common Stock underlying MTBV's 2003 PIPE's,  the May 2004 and the July 2004
PIPEs were issued under  exemptions  provided by  Regulation S or  Regulation D.
With the  exception  of Marr  Technologies  B.V.,  which is an  affiliate of the
Company  based  on  its  August  and  September   2003  PIPE   investments   and
participation  in the May 2004 PIPE, none of the entities listed above is or has
been an affiliate of the Company. Other than Marr Technologies B.V. , all of the
listed  investors  were  subject  to  ownership  limitations  restricting  their
ownership  of our stock to a maximum of 4.9% or 9.9%,  depending on the specific
agreement.

        (2) At December 16, 2004,  the holders have converted all but $60,000 of
principal of the convertible  debentures  issued since September 2002.  Based on
current  market  prices,  we  estimate  that  we  would  be  required  to  issue
approximately  0.4 million  additional shares of our common stock if the holders
elected to  convert  the  remaining  principal  and  accrued  interest  of their
debentures at this time. See also Note 12.


        (3) On July 18, 2003, the registration  statement for 52,500,000  shares
underlying the 8% Convertible Notes, the Other Restart Financings and $1,300,000
of the Mercator 12% and 10% Convertible  Debentures  became  effective (File No.
333-106862).  As a  result  of a  decline  in the  market  price  of  our  stock
subsequent to the effective date of the July 2003  registration  statement,  the
number of shares  registered was insufficient to permit the complete  conversion
of the notes and  debentures  into  registered  shares.  The  shares  underlying
certain of the convertible securities have become eligible for resale under Rule
144,  and certain  investors  have availed  themselves  of that  eligibility  to
convert  restricted  shares issued  pursuant to  conversions  into  free-trading
shares.  On July 8, 2004,  the  registration  statement  for  83,056,050  shares
underlying Marr Private  Placements,  the May 2004 PIPE, certain of the Mercator
12%  Convertible  Debentures,   approximately  12.2  million  additional  shares
attributable to financings included in the July 2003 registration  statement and
approximately  3.3 million shares issued or issuable to vendors  consultants and
other  parties who agreed to accept  shares of our Common  Stock in lieu of cash
became  effective  (File No.  333-116491).  On July 28, 2004,  the  registration
statement for 6,472,800 shares of our Common Stock underlying the July 2004 PIPE
and related warrants became effective (File No. 333-117439).

        (4) Includes fee shares.

        (5) On April 30,  2003,  when the market  price of the common  stock was
$0.75,  we and BNC Bach amended the  conversion  price to eliminate a conversion
price ceiling of $1.50 per share and to increase the discount  applicable to the
conversion  price  from  40% to 50%.  In  return  for this  modification  of the
conversion  price,  BNC Bach agreed to extend the maturity of the note until May
10, 2004. BNC Bach subsequently  converted the outstanding principal and accrued
interest into shares of our common stock.


        (6)  Reflects  a 10%  cash  commitment  fee on  the  entire  $2  million
commitment  paid to The Mercator  Group less  additional  fees and expenses.  We
registered  shares underlying  $1,300,000 of the total $2,000,000  commitment in
July 2003 and the shares  underlying the final $700,000 of this  commitment were
included in our June 2004 registration statement.


        (7) In conjunction  with the issuance of the $1 million 10%  convertible
debenture to Mercator  Focus Fund,  L.P., we used the proceeds to repay the $0.3
million  outstanding   principal  balance  of  the  12%  convertible   debenture
previously  issued to Mercator  Momentum Fund, L.P. plus accrued  interest.  The
balance of costs incurred represents transactional and legal fees.

        (8) On March 31,  2003,  when the market  price of our Common  Stock was
$0.885, we amended the conversion price to eliminate a conversion price floor of
$1.50 per share in return  for an  extension  of time in which to  register  the
shares of common stock underlying the various Mercator financings.

        (9) The Securities Purchase Agreements for both transactions between the
Company  and  Marr   Technologies   B.V.  require  that  we  provide   cost-free
registration  rights to Marr;  however,  Marr is subject  to a one-year  lock-up
provision following the transaction date with respect to the shares purchased.

        (10) On January 14, 2004,  when the market price of our common stock was
$0.60, we extended the maturity date of the following  debentures until July 14,
2004:

            o     10%  Convertible  Debenture  dated  January 14, 2003 issued to
                  Mercator Focus Fund, LP

            o     10%  Convertible  Debenture  dated  January 30, 2003 issued to
                  Mercator Momentum Fund, LP

            o     10%  Convertible  Debentures  dated  March 13,  2003 issued to
                  Mercator Focus Fund, and

            o     12%  Convertible  Debenture  dated  April 29,  2003  issued to
                  Mercator Momentum Fund, LP.

In return for the  extension  of the  maturity  dates,  we have agreed to pay an
additional  extension fee equal to 2% of the outstanding  principal  balance per
month  until the  earlier  of the  extended  maturity  date or  conversion.  The
extension  fee is  payable  1% in cash and 1% in  shares  of our  common  stock.
Additionally,  we agreed to file a registration  statement  including the shares
potentially  applicable to the conversion of the outstanding  debenture balances
by no later than April 29, 2004. On April 23, 2004, when the market price of our
Common  Stock was $0.625,  we and the various  Mercator  Funds  agreed to extend


                                      II-8



until May 14, 2004 the period for filing the  registration  statement  including
the shares issued or potentially issuable upon conversion.  On May 7, 2004, when
the market  price of our common  stock was $0.48 per share,  we and the  various
Mercator  Funds  agreed  to  further  extend  from  May 14,  2004  until 21 days
following  the closing of a private  placement  of equity  financing of at least
$5,000,000,  but in any case to no later than June 30, 2004, the period in which
we are required to file a registration  statement including shares of our common
stock issued or potentially issuable upon conversion.  Such shares were included
in our June 15, 2004  registration  statement,  which was declared  effective on
July 8, 2004. All of the subject convertible  debentures were converted prior to
the extended maturity date.

        (11) On January 23, 2004,  when the market price of our common stock was
$0.695, we and Marr agreed to extend the registration rights period attributable
to  5,181,818  shares of our common  stock  issued in  conjunction  with  Marr's
conversion  of  $570,000  principal  amount  of the  Company's  12%  Convertible
Debentures  from  February  27,  2004 to  April  29,  2004.  In  return  for the
extension,  we agreed to include in our next registration statement an aggregate
of 28,333,333  shares of our common stock purchased by Marr in PIPE transactions
in the third  quarter of 2003.  On April 23 2004,  when the market  price of the
Common Stock was $0.625,  we MTBV agreed to extend until May 14, 2004 the period
for filing the registration  statement  including the shares issued to MTBV upon
conversion of the 12% convertible  debenture and in the 2003 PIPE  transactions.
On May 7 2004,  when the market  price of our common  stock was $0.48 per share,
MTBV  agreed to further  extend from May 14,  2004 until 21 days  following  the
closing of a private placement of equity financing of at least  $5,000,000,  but
in any case to no later than June 30, 2004,  the period in which we are required
to file a registration  statement including shares of our common stock issued to
MTBV  upon  conversion  of the 12%  convertible  debenture  and in the 2003 PIPE
transactions.  Such  shares  were  included  in our June 15,  2004  registration
statement, which was declared effective on July 8, 2004.

        (12) The holders  claim an earlier  transaction  date with  respect to a
conversion of the debentures,  which we dispute.  These  debentures have not yet
been  converted.   Assuming  immediate  conversion  at  the  earlier,   disputed
transaction  date,  the number of shares of common stock issuable to Logisticorp
and Southwest Resource Preservation would be 213,903 and 427,807,  respectively.
While  reserving  our rights with repect to the number of shares  calculated  as
issuable based on the disputed  transaction  date, we registered  that number of
shares of  Common  Stock in our June 15,  2004  registration  statement  pending
resolution  of the dispute.  The ultimate  resolution  of the  transaction  date
dispute may  determine  the number of shares of our stock to which the holder is
entitled upon conversion.

        (13) The shares  issued  pursuant to the May 2004 PIPE and the July 2004
PIPE and the related warrants for each have an  anti-dilution  feature that will
require us to issue  additional  shares to the PIPE  investors  and modify their
warrants if we subsequently issue additional equity at a per share price of less
than $0.40 for a period of one year from the respective  closing  dates,  except
under the provisions of previously  outstanding  convertible debt, option plans,
or option or warrant agreements.

Marr Credit Facility

On November  13,  2003,  when the market price of our common stock was $0.88 per
share, we and Marr, our largest stockholder,  entered into an agreement in which
Marr agreed to provide us up to an  aggregate of  $10,000,000  (the "Marr Credit
Facility")  pursuant  to  promissory  notes  that  we may  issue  to  Marr on an
as-needed  basis (the  "Notes").  Each Note will bear interest at the rate of 5%
per annum and will have a 12-month term. The Marr Credit  Facility was available
during the period beginning on February 28, 2004 and ending on May 31, 2004. The
aggregate  amount  available  under the Marr Credit  Facility is  proportionally
reduced by the amount of any equity financing obtained by the Company during the
term of the Marr  Credit  Facility.  Marr has  participation  rights in any such
equity  financing  on the same  terms as the other  investors.  The Marr  Credit
Facility provided for earlier  termination as of March 31, 2004, if we failed to
have our common  stock  listed on an  established  stock  exchange by that date.
Moreover,   upon  the  failure  to  obtain  such  stock  exchange  listing,  any
outstanding  Notes would be due and payable on April 30, 2004. As  consideration
for the Marr Credit Facility,  we issued to a party designated by Marr a warrant
to purchase 375,000 shares of our common stock at an exercise price of $0.80 per
share.  The  warrant is  immediately  exercisable  and  expires  two years after
issuance on November 12, 2005.

On March 19,  2004,  when the market  price of our  common  stock was $0.575 per
share,  we and Marr amended the Marr Credit  Facility to increase the  aggregate
amount  available under the Marr Credit Facility to $15,000,000 and to eliminate
the  termination  provision  upon  failure to have the common stock listed on an
established  stock exchange by March 31, 2004. As additional  consideration  for
the amendment of the Marr Credit  Facility,  we issued to a party  designated by
Marr an additional  warrant to purchase 400,000 shares of our common stock at an
exercise price of $0.46 per share.  This warrant is immediately  exercisable and
expires two years from its date of issuance on March 18, 2006.


                                      II-9




On May 26, 2004,  when the market price of the Common Stock was $0.46 per share,
we and MTBV again amended the Marr Credit Facility whereby MTBV has committed to
subscribe for up to  $5,000,000  of  Promissory  Notes that we may issue through
December  31,  2004,  should  our Board of  Directors  unanimously  approve  the
issuance of one or more such notes before the commitment  period  expires.  Marr
currently has two designated  representatives serving on our Board of Directors.
Any Notes issued pursuant to this second  amendment will bear interest at 9% per
annum and will have a  maturity  date of May 31,  2005.  The  $5,000,000  amount
available under the amended Marr Credit Facility is reduced by the amount of any
equity  financing  obtained by the Company after the May 26, 2004 effective date
of the second  amendment  and through the December 31, 2004  commitment  period,
exclusive of the proceeds from the May 2004 Private Placement.  Accordingly, the
commitment  has been  reduced to  approximately  $3.6 million as a result of the
closing  of the July  2004  PIPE.  As  consideration  for the  extension  of the
commitment period reflected in the second amendment of the Marr Credit Facility,
we issued to MTBV a warrant to purchase 500,000 shares of our Common Stock at an
exercise price of $0.40 per share.  This warrant is immediately  exercisable and
expires  two  years  from its  date of  issuance  on May 26,  2006.  The  shares
underlying these three warrants were included in our June 15, 2004  registration
statement.  At December 16, 2004,  we have issued no Notes under the Marr Credit
Facility.


Warrants, Options and Stock Grants


Since January 2002, we have entered into various  contracts and agreements  with
consultants  who have agreed to accept payment for their services in the form of
warrants,  options and/or stock grants.  We have obtained various services under
these arrangements,  including legal,  financial,  business advisory,  and other
services  including  business  introductions  and  arrangements  with respect to
potential  domestic and  international  product placement and the development of
potentially  synergistic  relationships with appropriate public service or other
governmental and  non-governmental  organizations.  We have generally issued the
warrants at a discount to the then-current  market price and have registered the
shares   underlying  the  warrants,   options  and  stock  grants  on  Form  S-8
Registration  Statements for resale by the  consultants.  We have, since January
2002, issued  approximately  10.5 million shares of our common stock as a result
of warrant or option  exercises  and stock  grants  related to these  consulting
agreements, of which approximately 7.9 million shares were issued during 2003.


In May 2002, we issued  warrants and options to purchase  633,333  shares of our
common stock under  agreements  with  consultants to perform  legal,  financial,
business  advisory  and  other  services  associated  with  the  restart  of our
operations.  The warrants were issued at $0.45 per share on May 9, 2002 when the
market price of our common stock was $0.90 per share.  The option was granted at
$0.90 per share on May 10,  2002,  when the market price of our common stock was
$0.90 per share. All of the warrant and option grants were  non-forfeitable  and
fully-vested  at the date of  issuance  and were  registered  for  resale by the
consultants  under Form S-8.  The  consultants  exercised  all the  warrants and
options and we issued 633,333 shares and received proceeds of $292,500.  All but
one of the consulting  agreements  discussed above expired in August 2002 and we
entered  into  new  agreements  with  certain  of  the  consultants  for  legal,
financial,  business advisory,  and other services  including  introductions and
arrangements  with  respect to  potential  domestic  and  international  product
development  of  synergistic   relationships  with  appropriate  public  service
organizations.  In November 2002, we issued warrants to purchase  950,000 shares
of our  common  stock  and  stock  grants  for  70,000  shares  of our  stock to
consultants under the terms of these new agreements.  We issued 350,000 warrants
at an exercise  price of $1.50 per share on  November  1, 2002,  when the market
price of our stock was $4.20 per share. We issued an additional 600,000 warrants
at an exercise price of $1.50 on November 20, 2002, when the market price of our
common  stock was $2.70.  All of the  warrant  grants  were  non-cancelable  and
fully-vested  at the date of  issuance  and were  registered  for  resale by the
consultants  under Form S-8. By February 2003, the consultants had exercised all
the warrants and we had received aggregate proceeds of $1.425 million. We issued
986,667  shares of our common  stock  pursuant to the  exercises of the November
2002 warrant and stock grants.

In January and February 2003, we entered into new contracts and extended certain
other  contracts  with  existing  consultants  to perform  services as described
above.  On February 14, 2003,  when the market price of our stock was $2.01,  we
issued warrants exercisable at $1.50 per share and stock grants for an aggregate
of 975,216 shares of our common stock as compensation  for these  services.  The
warrants were  non-cancelable  and fully-vested at the date of issuance.  By May
31, 2003, the consultants  had exercised  warrants to purchase all of the shares
granted to them and we had received proceeds of $0.8 million.


                                     II-10



During March 2003, when the market price of our stock ranged from $1.32 to $1.50
per share,  we issued  warrants  exercisable at $0.75 per share and stock grants
for an aggregate of 1,350,400 as compensation for services under new or extended
contracts.  The warrants were  non-cancelable  and  fully-vested  at the date of
issuance.  By May 31, 2003, the consultants  had exercised  warrants to purchase
all of the shares granted to them and we had received  proceeds of approximately
$0.9 million.

In April  2003,  when the price of our stock  ranged  from  $0.81 to $0.885  per
share, we entered into additional  contracts,  extended certain  contracts,  and
modified certain other contracts with existing  consultants who agreed to settle
a portion of the  outstanding  balance due for services under their contracts in
stock.  We issued  warrants at $0.75 per share and stock grants for an aggregate
of 1,490,600  shares of our common stock as compensation or settlement for these
services.  The warrants  were  non-cancelable  and  fully-vested  at the date of
issuance.  By May 31, 2003, the consultants  had exercised  warrants to purchase
all of the shares granted to them and we had received  proceeds of approximately
$0.1 million.

In May 2003, when the price of our stock ranged from $0.552 to $0.576 per share,
we again entered into new contracts,  extended certain  contracts,  and modified
certain other contracts with existing consultants who agreed to settle a portion
of the  outstanding  balance due for services under their contracts in shares of
stock.  We issued  warrants at $0.30 per share and stock grants for an aggregate
of 2,080,305  shares of our common stock as compensation or settlement for these
services.  The warrants  were  non-cancelable  and  fully-vested  at the date of
issuance.  By September 30, 2003,  the  consultants  had  exercised  warrants to
purchase  all of the shares  granted  to them and we had  received  proceeds  of
approximately $0.5 million.

In July 2003,  when the price of our stock ranged from $0.11 to $0.30 per share,
we  extended a contract  for  consulting  and other  services  and  granted  the
consultant  a warrant to purchase  722,500  shares of our common stock at 50% of
the closing market price on the date of any exercise as  compensation  under the
contract.  The warrant was granted as fully-vested  and expired on September 30,
2003. By September 30, 2003,  the consultant had exercised the entire warrant at
prices  ranging  from $0.08 to $0.61 per share and we had  received  proceeds of
approximately  $0.4  million.  Also during July 2003,  we issued stock grants to
consultants  for  an  aggregate  of  356,344  shares  of  our  common  stock  as
compensation under their contracts.


On August 20, 2003,  when the price of our stock was $0.18 per share,  we issued
consulting contracts to two new consultants pursuant to which we issued warrants
for 100,000  shares each,  exercisable  at $0.18 per share.  The  warrants  were
non-cancelable  and fully-vested at the date of issuance.  In December 2004, one
of the consultants  exercised  warrants to purchase 100,000 shares of our common
stock.  At December 16, 2004, the other  consultant has not exercised any of the
warrants granted to him.


In  September  2003,  when the price of our stock ranged from $0.50 to $1.80 per
share,  we  issued  an  aggregate  of  800,000  shares  of our  common  stock to
consultants  and other  service  providers who agreed to take shares of stock in
lieu of cash as compensation under their contracts.

In October and November  2003,  when the price of our stock ranged from $0.53 to
$1.65 per share, we issued an aggregate of 125,000 shares of our common stock to
consultants  and other  service  providers who agreed to take shares of stock in
lieu of cash as compensation under their contracts.

In  February  2004,  when the price of our stock was $0.67 per share,  we issued
500,000  shares of our  common  stock to a  consultant  who had agreed to accept
shares of stock as a portion of its compensation  under a consulting  agreement.
We issued  approximately 67,000 additional shares of our common stock during the
first  quarter  of 2004 to  another  consultant  under the terms of a  long-term
consulting agreement.

In May  2004,  when the  price of our  stock was  $0.465  per  share,  we issued
warrants to purchase  150,000 shares of our common stock at an exercise price of
$0.50 as a portion of the compensation under a consulting contract. The warrants
were exercisable immediately and remain so for a period of five years.

In June 2004, when the price of our stock was $0.52 per share, we issued 250,000
shares of our common  stock to a consultant  who had agreed to accept  shares of
stock as a portion of its compensation under a consulting agreement.


                                     II-11



To conserve cash and to obtain goods and  services,  the Company may continue to
issue  options and warrants at discounts to market or issue direct stock grants.
In the event that the Company  issues  additional  options and  warrants,  it is
anticipated that the securities will contain cost-free registration rights which
will be granted to holders of the  options and  warrants,  and that there may be
dilution to the Company's existing stockholders.

Capital Lease

In September  2004,  when the price of our stock was $0.38 per share, we entered
into  a  lease  for  $500,000  of  equipment  used  in our  Rockville,  Maryland
manufacturing  facility.  The  lease  has a  minimum  term  of 3  years  with an
extension  option of 3 months,  and requires  monthly payments of $17,250 during
the initial term and extension periods. In conjunction with the lease, we issued
to the lessor a warrant to purchase 55,000 shares of our common stock at a price
of $0.4060 per share. The warrant is exercisable for a period of three years.


Intellectual  Property  and  Equipment
Purchase Using Stock

On September  30, 2004,  when the market price of our common stock was $0.39 per
share and  pursuant  to  Regulation  S, we entered  into the  License  Agreement
pursuant  to  which  we are  required  to pay to Ani  Biotech  an  aggregate  of
1,232,840 Euros (approximately US $1,500,000) in either our common stock or cash
to acquire certain licenses and manufacturing  equipment. On September 30, 2004,
we issued 1,172,205  restricted shares of our common stock to Ani,  representing
the first  installment  under the  License  Agreement.  These  shares  are being
registered in this registration  statement.  Subsequent  installments  under the
License  Agreement  are due over the next several  months,  beginning  five days
following the effectiveness of this registration statement. Such payments may be
paid  in  registered  shares  of our  common  stock,  or in  cash,  at our  sole
discretion.  Should  we  elect  to  file  a  subsequent  registration  statement
registering such shares, the License Agreement provides that we would issue such
shares  of our  Common  Stock to Ani  Biotech  at a price  equal to the  average
closing price of our Common Stock as quoted on the American  Stock  Exchange for
the five days immediately preceding the transfer, but not at less than $0.40 per
share.

 ITEM 28.    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, as amended;

            (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% change in the maximum  aggregate
                  offering price set forth in the  "Calculation  of Registration
                  Fee" table in the effective registration statement; and

            (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.

      2.    That,  for the  purpose  of  determining  any  liability  under  the
            Securities  Act  of  1933,  as  amended,  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.

      4.    The undersigned  Registrant  hereby undertakes that, for purposes of
            determining  any  liability  under the  Securities  Act of 1933,  as
            amended,  each filing of the Registrant's  Annual Report pursuant to
            Section  13(a) or Section  15(d) of the  Securities  Exchange Act of
            1934,  as  amended,   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.


                                     II-20



      5.    Insofar  as  indemnification   for  liabilities  arising  under  the
            Securities Act of 1933, as amended (the "Act"),  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.

       6.    The undersigned registrant hereby undertakes to deliver or cause to
             be  delivered  with  the  prospectus,  to each  person  to whom the
             prospectus  is sent or given,  the latest annual report to security
             holders that is  incorporated  by reference in the  prospectus  and
             furnished  pursuant to and meeting the requirements of Rule 14-a or
             Rule 14c-3 under the  Securities  Exchange Act of 1934, as amended;
             and, where interim financial  information  required to be presented
             by  Article  3  of  Regulations  S-X  are  not  set  forth  in  the
             prospectus,  to deliver, or cause to be delivered to each person to
             whom the prospectus is sent or given,  the latest  quarterly report
             that is specifically incorporated by reference in the prospectus to
             provide such interim financial information.
