           AND RIGHTS OF SERIES D CONVERTIBLE PREFERRED STOCK

      Cel-Sci Corporation (the "Company"),  a corporation organized and existing
under the Colorado  Corporation  Code,  does hereby  certify  that,  pursuant to
authority  conferred  upon  the  Board  of  Directors  of  the  Company  by  the
Certificate  of  Incorporation,  as amended,  of the  Company,  and  pursuant to
Section  7-106-102 of the Colorado  Corporation  Code, the Board of Directors of
the Company at a meeting duly held, adopted resolutions (i) authorizing a series
of the  Company's  previously  authorized  preferred  stock,  par value $.01 per
share,  and (ii)  providing  for the  designations,  preferences  and  relative,
participating, optional or other rights, and the qualifications,  limitations or
restrictions  thereof,  of Ten  Thousand  (10,000)  shares of Series D Preferred
Stock of the Company, as follows:

      RESOLVED,  that the Company is authorized  to issue Ten Thousand  (10,000)
shares of Series D Preferred Stock (the "Preferred Shares"),  par value $.01 per
share,  which shall have the following  powers,  designations,  preferences  and
other special rights:

      1.  Dividends.  The  Preferred  Shares  shall pay a dividend  equal to two
percent (2%) per month,  payable on the first day of each month with appropriate
proration for partial months. Such dividend shall only be payable if, and during
such time as, (i) the Registration  Statement has not been declared effective by
the SEC prior to the date  that is 120 days  after the  Closing  Date;  (ii) the
Registration Statement does not cover the resale of all of the Conversion Shares
or the Company gives notice that Common Stock issued or issuable upon conversion
of the Preferred Shares cannot be sold under the Registration  Statement for any
period of thirty (30) consecutive days after the date the Registration Statement
has been declared  effective by the SEC; (iii) the Common Stock is not listed on
the Nasdaq  National  Market,  the Nasdaq  Small Cap Market,  The New York Stock
Exchange,  Inc. or The American Stock Exchange, Inc. for a period of twenty (20)
consecutive trading days.

      2. Holder's  Conversion of Preferred  Shares. A holder of Preferred Shares
shall have the right, at such holder's  option,  to convert the Preferred Shares
into shares of the Company's common stock, $.01 par value per share (the "Common
Stock"), on the following terms and conditions:


            (a)  Conversion  Right.  At any time or times after the Closing Date
until 3 years after Closing, any holder of Preferred Shares shall be entitled to
convert any whole number of Preferred  Shares into fully paid and  nonassessable
shares  (rounded to the nearest  whole share in  accordance  with  Section  2(i)
below) of Common Stock,  at the Conversion  Rate (as defined  below);  provided,
however,  that in no event  shall any holder be  entitled  to convert  Preferred
Shares in excess of that number of Preferred Shares which, upon giving effect to
such  conversion,  would cause the  aggregate  number of shares of Common  Stock
beneficially  owned by the  holder  and its  affiliates  to  exceed  4.9% of the
outstanding  shares of the Common Stock following such conversion and,  provided
further,  a holder may elect,  upon sixty one (61) days prior written  notice to
the Company,  not to be bound by such  provision.  For purposes of the foregoing
proviso,  the aggregate number of shares of Common Stock  beneficially  owned by
the holder and its affiliates shall include the number of shares of Common Stock
issuable  upon  conversion  of the  Preferred  Shares with  respect to which the
determination of such proviso is being made, but shall exclude the



number of shares of Common Stock which would be issuable upon (i)  conversion of
the remaining,  nonconverted  Preferred Shares  beneficially owned by the holder
and its  affiliates  and (ii)  exercise  or  conversion  of the  unexercised  or
unconverted portion of any other securities of the Company  (including,  without
limitation,  any  warrants)  subject to a limitation  on  conversion or exercise
analogous to the limitation  contained herein  beneficially  owned by the holder
and its affiliates.  Except as set forth in the preceding sentence, for purposes
of this paragraph,  beneficial  ownership shall be calculated in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended.  Any Preferred
Shares  outstanding  on 3 year  anniversary  of Closing will be  converted  into
shares of Common Stock at the applicable Conversion Price (as defined below).

            (b) Conversion  Price. The number of shares of Common Stock issuable
upon conversion of each of the Preferred Shares shall be determined according to
the following formula (the "Conversion Rate"):

                                    1000
                            Conversion Price

                  (i) At any time or times on and prior to the Anniversary Date,
the "Conversion Price" means the Fixed Conversion
Price.

                  (ii) At any time or times on and  following  the  trading  day
following the  Anniversary  Date or upon occurrence of a Triggering  Event,  the
"Conversion  Price"  means the lesser of (a) the  Market  Price or (b) the Fixed
Conversion Price.

For purposes of this Certificate of Designations, the following terms shall have
the following meanings:

                        (1)   "Anniversary  Date"  means the  earlier of
(A) 270 days after the Closing Date, or the first trading day  thereafter or (B)
the trading day  immediately  following a period of 5  consecutive  trading days
during  which the Closing Bid Price (as  defined  below) of the Common  Stock is
equal to or less than 50% of the Closing Price.

                        (2)   "Fixed  Conversion  Price"  means  120% of
the Closing Price, subject to adjustment as provided herein;

                        (3)   "Market  Price"  means the  average of the
weighted  average prices on AMEX (as currently  shown by the ticker symbol HIV.A
as reported by  Bloomberg  Financial  Markets  ("Bloomberg"))  of the  Company's
Common Stock for any two consecutive  trading days, chosen by the holder, in the
ten trading  day period  ending on the day prior to a holder's  submission  of a
Conversion  Notice less one half of the difference  between the average  Closing
Ask Price and average  Closing Bid Price of the  Company's  Common  Stock during
such two trading days;

                        (4)   "Average   Market   Price"   means,   with
respect to any  security  for any period,  that price which shall be computed as
the  arithmetic  average of the Closing  Bid Prices (as defined  below) for such
security for each trading day in such period;

                        (5)   "Closing  Bid  Price" or  "Closing  Asked
Price"  means,  for any  security as of any date,  the last closing bid price or
asked price,  respectively,  for such  security on the American  Stock  Exchange
("AMEX") as reported  by  Bloomberg,  as  currently  shown by the ticker  symbol
HIV.A,  or, if the AMEX is not the principal  trading  market for such security,
the last closing bid price or asked price, respectively, of such security on the
principal securities exchange or trading market where such security is listed or
traded as reported by  Bloomberg,  or if the  foregoing  do not apply,  the last
closing  bid  price  or  asked  price,  respectively,  of such  security  in the
over-the-counter



market  on the  electronic  bulletin  board for such  security  as  reported  by
Bloomberg, or, if no closing bid price or asked price, respectively, is reported
for such security by Bloomberg, the last closing trade price of such security as
reported by  Bloomberg,  or, if no last closing trade price is reported for such
security  by  Bloomberg,  the  average  of  the  bid  prices  or  asked  prices,
respectively,  of any market  makers for such  security as reported in the "pink
sheets" by the National  Quotation Bureau,  Inc. If the Closing Bid Price or the
Closing Asked Price cannot be  calculated  for such security on such date on any
of the  foregoing  bases,  the  Closing Bid Price or the  Closing  Asked  Price,
respectively,  of such  security on such date shall be the fair market  value as
mutually  determined by the Company and the holders of Preferred  Shares. If the
Company  and the holders of  Preferred  Shares are unable to agree upon the fair
market value of the Common Stock,  then such dispute shall be resolved  pursuant
to Section  2(e)(iii)  below with the term "Closing Bid Price" or "Closing Asked
Price,"  respectively,  being  substituted  for the term "Average Market Price."
(All such  determinations  to be appropriately  adjusted for any stock dividend,
stock, split or other similar transaction during such period).

                        (6)   "Closing  Price"  means the average of the
Closing  Bid  Price of the  Common  Stock  for  five  consecutive  trading  days
immediately proceeding the Closing Date; and

                        (7) "Closing Date" means the initial date of
issuance of the Preferred Shares.

                  (c)  Adjustment  to  Conversion  Price --  Dilution  and Other
Events.  In  order  to  prevent  dilution  of  the  rights  granted  under  this
Certificate of Designations,  the Conversion Price will be subject to adjustment
from time to time as provided in this Section 2(c).

                  (i)  Adjustment  of Fixed  Conversion  Price upon  Issuance of
Common Stock.  If and whenever on or after the date of issuance of the Preferred
Shares,  the Company  issues or sells,  or is deemed to have issued or sold, any
shares of Common  Stock  (other than shares of Common  Stock deemed to have been
issued by the  Company in  connection  with an  Approved  Stock Plan (as defined
below)) for a consideration per share less than the lesser of the Average Market
Price of the Common Stock for the previous five (5) consecutive  trading days or
the twenty (20) consecutive trading days immediately  preceding the date of such
issuance or sale (the "Applicable Price"),  then immediately after such issue or
sale,  the Fixed  Conversion  Price  shall be reduced to an amount  equal to the
product of (x) the Fixed  Conversion Price in effect  immediately  prior to such
issue or sale and (y) the quotient determined by dividing (1) the sum of (I) the
product derived by multiplying  the Applicable  Price by the number of shares of
Common Stock Deemed  Outstanding  (as defined below)  immediately  prior to such
issue or sale, and (II) the consideration,  if any, received by the Company upon
such issue or sale, by (2) the product derived by multiplying (I) the Applicable
Price  by  (II)  the  number  of  shares  of  Common  Stock  Deemed  Outstanding
immediately  after such issue or sale. For purposes of determining  the adjusted
Fixed  Conversion  Price under this  Section  2(c)(i),  the  following  shall be
applicable:

                        (A)   Issuance of Rights or Options.      If
the  Company in any manner  grants or sells any Option and the lowest  price per
share for which any one share of Common  Stock is issuable  upon the exercise of
any such Option,  or upon  conversion  or exchange of any  Convertible  Security
issuable upon exercise of any such Option, is less than the Applicable Price (as
defined  above)  in  effect  on the day  immediately  prior  to the  time of the
granting or sale of such Option, then such share of Common Stock shall be deemed
to be outstanding and to have been issued and sold by the Company at the time of
the  granting or sale of such Option for such price per share.  For  purposes of
this  paragraph,  the "lowest  price per share for which any one share of Common
Stock is issuable" shall be equal to the sum of the lowest



amount of  consideration  (if any)  received or  receivable  by the Company with
respect  to any one  share of  Common  Stock  upon the  granting  or sale of the
Option,  upon  exercise  of the Option and upon  conversion  or  exchange of any
Convertible   Security  issuable  upon  exercise  of  such  Option.  No  further
adjustment of the Fixed  Conversion Price shall be made upon the actual issue of
such Common Stock or such Convertible Security upon the exercise of such Options
or upon the actual  issue of such Common  Stock upon  conversion  or exchange of
such Convertible Security.

                        (B)   Issuance of Convertible Securities. If
the  Company  in any manner  issues or sells any  Convertible  Security  and the
lowest price per share for which any one share of Common Stock is issuable  upon
conversion or exchange thereof,  calculated on the date of such issue or sale of
such convertible  security, is less than the Applicable Price (as defined above)
in effect on the day immediately prior to the time of such issue or sale of such
convertible  security,  then such  share of Common  Stock  shall be deemed to be
outstanding  and to have been  issued and sold by the Company at the time of the
issuance or sale of such  Convertible  Securities for such price per share.  For
the purposes of this  paragraph,  the "lowest  price per share for which any one
share of  Common  Stock  is  issuable"  shall be equal to the sum of the  lowest
amounts of  consideration  (if any)  received or  receivable by the Company with
respect  to any one  share of  Common  Stock  upon the  issuance  or sale of the
Convertible  Security and upon the  conversion  or exchange of such  Convertible
Security. No further adjustment of the Fixed Conversion Price shall be made upon
the  actual  issue of such  Common  Stock upon  conversion  or  exchange  of any
Convertible Security, and if any such issue or sale of such Convertible Security
is made upon  exercise of any Options for which  adjustments  of the  Conversion
Price had been or are to be made  pursuant to other  provisions  of this Section
2(c)(i),  no further  adjustment of the Conversion Price shall be made by reason
of such issue or sale.

                        (C)   Change in Option Price or Conversion Rate.
If the purchase price provided for in any Option,  the additional  consideration
(if any)  payable  upon the issue,  conversion  or exchange  of any  Convertible
Security or the rate at which any  Convertible  Security is convertible  into or
exchangeable for Common Stock changes at any time, the Fixed Conversion Price in
effect at the time of such  change  shall be adjusted  immediately  to the Fixed
Conversion Price which would have been in effect at such time had such Option or
Convertible  Security  originally  provided  for such  changed  purchase  price,
additional  consideration  or  conversion  rate, as the case may be, at the time
initially  granted,  issued or sold.  If the terms of any Option or  Convertible
Security which was  outstanding as of the Closing Date are changed in the manner
described in the immediately preceding sentence, then such Option or Convertible
Security and the Common Stock  deemed  issuable  upon  exercise,  conversion  or
exchange  thereof  shall be deemed  to have  been  issued as of the date of such
change;  provided  that no  such  change  shall  at any  time  cause  the  Fixed
Conversion  Price hereunder to be increased,  except that, in the event any such
Options or Convertible  Securities  expire,  the Fixed Conversion Price shall be
readjusted to remove the effect of such Options or Convertible Securities.

                        (D)   Certain   Definitions.   For  purposes  of
determining the adjusted Fixed Conversion Price under this Section 2(c)(i),  the
following terms have meanings set forth below:

                              (I)         "Options"  means  any  rights,
warrants  or  options  to  subscribe  for or  purchase  Common  Stock or
Convertible Securities.

                              (II)  "Convertible  Securities"  means any
stock or securities (other than Options) directly or indirectly convertible into
or exchangeable for Common Stock.

                              (III) "Approved  Stock  Plan"  shall  mean
any  contract,  plan or  agreement  which  has  been  approved  by the  Board of
Directors  of the Company,  pursuant to which the  Company's  securities  may be
issued to any employee, officer, director, consultant or other service provider.




                              (IV)  "Common  Stock  Deemed  Outstanding"
means,  at any given  time,  the  number of  shares  of  Common  Stock  actually
outstanding at such time, plus the number of shares of Common Stock deemed to be
outstanding pursuant to Section 2(c)(i) hereof regardless of whether the Options
or Convertible  Securities are actually  exercisable at such time, but excluding
any shares of Common Stock issuable upon conversion of the Preferred Shares.


                        (E)   Effect  on  Fixed  Conversion  Price  of
Certain   Events.   For  purposes  of  determining  the  adjusted  Fixed
Conversion  Price under this Section  2(c)(i),  the  following  shall be
applicable:

                              (I)         Calculation of  Consideration
Received.  If any Common Stock, Options or Convertible  Securities are issued or
sold or deemed to have been issued or sold for cash, the consideration  received
therefor  will be deemed  to be the  amount  received  by the  Company  therefor
calculated  on the date of  issuance  or sale  without  giving  effect  to sales
commission or offering expenses,  if any, upon the sale,  conversion or exercise
of such securities.  In case any Common Stock, Options or Convertible Securities
are  issued or sold for a  consideration  other  than  cash,  the  amount of the
consideration  other than cash received by the Company will be the fair value of
such consideration,  except where such consideration consists of securities,  in
which case the  amount of  consideration  received  by the  Company  will be the
Average Market Price of such securities for the twenty (20) consecutive  trading
days  immediately  preceding  the date of  receipt.  In case any  Common  Stock,
Options or Convertible  Securities are issued to the owners of the non-surviving
entity in  connection  with any  merger in which the  Company  is the  surviving
entity the amount of consideration  therefor will be deemed to be the fair value
of such portion of the net assets and business of the non-surviving entity as is
attributable  to such Common Stock,  Options or Convertible  Securities,  as the
case may be. The fair value of any  consideration  other than cash or securities
will be  determined  jointly by the Company and the holders of a majority of the
Preferred Shares then outstanding. If such parties are unable to reach agreement
within ten (10) days after the occurrence of an event  requiring  valuation (the
"Valuation  Event"),  the fair value of such  consideration  will be  determined
within  forty-eight  (48) hours of the tenth (10th) day  following the Valuation
Event by an  independent,  reputable  appraiser  selected  by the  Company.  The
determination  of such appraiser shall be deemed binding upon all parties absent
manifest error.

                              (II)  Integrated  Transactions.   In  case
any Option is issued in connection with the issue or sale of other securities of
the Company, together comprising one integrated transaction in which no specific
consideration is allocated to such Options by the parties thereto, consideration
given upon the grant of such Option will be deemed to be $.01.

                              (III) Treasury   Shares.   The  number  of
shares of Common  Stock  outstanding  at any given time does not include  shares
owned or held by or for the account of the Company,  and the  disposition of any
shares so owned or held will be considered an issue or sale of Common Stock.

                              (IV)  Record  Date.  If the Company  takes
a record of the holders of Common Stock for the purpose of entitling them (1) to
receive a dividend or other distribution  payable in Common Stock, Options or in
Convertible Securities or (2) to subscribe for or purchase Common Stock, Options
or Convertible Securities, then such



record  date will be deemed to be the date of the issue or sale of the shares of
Common  Stock  deemed to have been issued or sold upon the  declaration  of such
dividend or the making of such other distribution or the date of the granting of
such right of subscription or purchase, as the case may be.

                  (ii) Adjustment of Fixed  Conversion Price upon Subdivision or
Combination of Common Stock. If the Company at any time subdivides (by any stock
split, stock dividend, recapitalization or otherwise) one or more classes of its
outstanding  shares of Common Stock into a greater  number of shares,  the Fixed
Conversion  Price  in  effect  immediately  prior  to such  subdivision  will be
proportionately  reduced.  If the Company at any time combines (by  combination,
reverse stock split or otherwise) one or more classes of its outstanding  shares
of Common Stock into a smaller number of shares,  the Fixed  Conversion Price in
effect immediately prior to such combination will be proportionately increased.

                  (iii)  Adjustment of Market Price upon Issuance of Convertible
Securities.  If the Company in any manner issues or sells Convertible Securities
that are  convertible  into more than 500,000 shares of Common Stock (subject to
adjustment   for   stock   splits,    stock    dividends,    consolidation    or
recapitalizations)  at a price which  varies with the market price of the Common
Stock (the  formulation for such variable price being herein referred to as, the
"Variable  Price")  and such  Variable  Price is not  calculated  using the same
formula used to calculate  the Market Price in effect  immediately  prior to the
time of such issue or sale, the Company shall provide written notice thereof via
facsimile  and  overnight  courier  to  each  holder  of  the  Preferred  Shares
("Variable Notice") on the date of issuance of such Convertible  Securities.  If
the holders of Preferred  Shares  representing at least  two-thirds (2/3) of the
Preferred  Shares then  outstanding  provide  written  notice via  facsimile and
overnight  courier (the "Variable Price Election  Notice") to the Company within
five (5) business days of receiving a Variable  Notice that such holders  desire
to replace the Market Price then in effect with the Variable Price  described in
such  Variable  Notice,  the Company shall prepare and deliver to each holder of
the Preferred Shares via facsimile and overnight  courier a copy of an amendment
to this  Certificate of  Designations  (the  "Variable  Price  Amendment")  that
substitutes  the  Variable  Price  for the  Market  Price  (together  with  such
modifications  to this  Certificate of  Designations  as may be required to give
full effect to the  substitution  of the  Variable  Price for the Market  Price)
within five (5) business days after receipt of the requisite  number of Variable
Price  Election  Notices set forth above.  The Company  shall file such Variable
Price Amendment with the Secretary of State of the State of Colorado within five
(5) business days after delivery of the Variable Price  Amendment to the holders
of the Preferred Shares;  provided that in the event that the Company receives a
notice prior to the filing of the Variable  Price  Amendment from any holder who
has delivered a Variable Price Election  Notice in connection with such Variable
Price  Amendment  that such  holder  objects to the form of the  Variable  Price
Amendment,  the Company shall not file such Variable Price  Amendment until such
time  as the  Variable  Price  Amendment  has  been  revised  to the  reasonable
satisfaction  of such  holder and  approved  in  writing  by the  holders of the
Preferred Shares  representing at least two-thirds (2/3) of the Preferred Shares
then  outstanding.  Except as  provided  in the  preceding  proviso,  a holder's
delivery of a Variable Price Election Notice shall serve as the consent required
to amend this Certificate of Designations pursuant to Section 12 below.

                  (iv) Reorganization,  Reclassification,  Consolidation, Merger
or Sale. Any recapitalization,  reorganization, reclassification, consolidation,
merger,  sale of all or  substantially  all of the  Company's  assets to another
Person (as defined below) or other  transaction  which is effected in such a way
that holders of Common Stock are  entitled to receive  (either  directly or upon
subsequent  liquidation)  stock,  securities  or assets  with  respect  to or in
exchange  for Common Stock is referred to herein as "Organic  Change."  Prior to
the consummation of any Organic Change, the Company



will make  appropriate  provision  (in form and  substance  satisfactory  to the
holders of a majority of the Preferred  Shares then  outstanding) to insure that
each of the holders of the Preferred  Shares will  thereafter  have the right to
acquire and receive in lieu of or addition to (as the case may be) the shares of
Common  Stock  immediately   theretofore  acquirable  and  receivable  upon  the
conversion of such holder's Preferred Shares,  such shares of stock,  securities
or assets as may be issued or payable  with  respect to or in  exchange  for the
number  of  shares  of  Common  Stock  immediately  theretofore  acquirable  and
receivable  upon the  conversion  of such  holder's  Preferred  Shares  had such
Organic  Change  not  taken  place.  In any such  case,  the  Company  will make
appropriate  provision (in form and substance  satisfactory  to the holders of a
majority of the Preferred Shares then outstanding) with respect to such holders'
rights and  interests  to insure that the  provisions  of this  Section 2(c) and
Section  2(d)  below will  thereafter  be  applicable  to the  Preferred  Shares
(including,  in the case of any such consolidation,  merger or sale in which the
successor  entity or purchasing  entity is other than the Company,  an immediate
adjustment  of the Fixed  Conversion  Price to the value  for the  Common  Stock
reflected by the terms of such  consolidation,  merger or sale,  if the value so
reflected is less than the Fixed Conversion Price in effect immediately prior to
such  consolidation,  merger or sale).  The  Company  will not  effect  any such
consolidation,  merger or sale,  unless prior to the consummation  thereof,  the
successor  entity (if other than the Company)  resulting from  consolidation  or
merger or the entity purchasing such assets assumes,  by written  instrument (in
form and  substance  satisfactory  to the holders of a majority of the Preferred
Shares then outstanding),  the obligation to deliver to each holder of Preferred
Shares such shares of stock,  securities  or assets as, in  accordance  with the
foregoing  provisions,  such holder may be entitled to acquire.  "Person"  shall
mean an individual, a limited liability company, a partnership, a joint venture,
a corporation,  a trust, an unincorporated  organization and a government or any
department or agency thereof.

                  (v)  Certain   Events.   If  any  event  occurs  of  the  type
contemplated  by the provisions of this Section 2(c) but not expressly  provided
for by such provisions  (including,  without  limitation,  the granting of stock
appreciation rights, phantom stock rights or other rights with equity features),
then the Company's Board of Directors will make an appropriate adjustment in the
Conversion  Price so as to protect  the rights of the  holders of the  Preferred
Shares;  provided that no such adjustment will increase the Conversion  Price as
otherwise determined pursuant to this Section 2(c).

                  (vi) Notices.

                        (A)   Immediately  upon  any  adjustment  of the
Conversion Price, the Company will give written notice thereof to each holder of
Preferred  Shares,  setting  forth  in  reasonable  detail  and  certifying  the
calculation of such adjustment.

                        (B)   The Company  will give  written  notice to
each holder of  Preferred  Shares at least twenty (20) days prior to the date on
which the  Company  closes its books or takes a record  (I) with  respect to any
dividend or  distribution  upon the Common  Stock,  (II) with respect to any pro
rata  subscription  offer to  holders of Common  Stock or (III) for  determining
rights to vote with respect to any Organic  Change,  dissolution or liquidation;
provided  that in no event shall such notice be provided to such holder prior to
such information being made known to the public.

                        (C) The Company will also give written notice
to each holder of  Preferred  Shares at least twenty (20) days prior to the date
on which any Organic Change, dissolution or liquidation will take place.

                  (vii)  Notwithstanding  the  above,  the  provisions  of  this
Section 2(c) shall not apply to (i) shares of Common Stock issued in  connection
with any  underwritten  public  offering  (ii)  any  transaction  involving  the
Company's issuance of securities in



connection with any  partnership or joint venture,  the primary purpose of which
is not to raise equity capital,  (iii) issuance of securities by a subsidiary of
the Company, and (iv) any issuance of securities by the Company as consideration
for the acquisition of technology or rights to technology.

            (d)  Purchase  Rights.   In  addition  to  any  adjustments  of  the
Conversion  Price  pursuant to Section  2(c)  above,  if at any time the Company
grants,  issues  or sells  any  Options,  Convertible  Securities  or  rights to
purchase  stock,  warrants,  securities or other property pro rata to the record
holders of any class of Common Stock (the "Purchase  Rights"),  then the holders
of Preferred  Shares will be entitled to acquire,  upon the terms  applicable to
such Purchase Rights, the aggregate Purchase Rights which such holder could have
acquired if such holder had held the number of shares of Common Stock acquirable
upon complete  conversion of the Preferred Shares immediately before the date on
which a record is taken for the grant, issuance or sale of such Purchase Rights,
or, if no such  record is taken,  the date as of which  the  record  holders  of
Common Stock are to be determined for the grant,  issue or sale of such Purchase
Rights.

            (e) Mechanics of Conversion.  Subject to the Company's  inability to
fully satisfy its  obligations  under a Conversion  Notice (as defined below) as
provided for in Section 4 below:

                  (i)  Holder's  Delivery  Requirements.  To  convert  Preferred
Shares into full shares of Common Stock on any date (the "Conversion Date"), the
holder  thereof  shall (A) deliver or transmit by  facsimile,  for receipt on or
prior to 11:59  p.m.,  Central  Time on such  date,  a copy of a fully  executed
notice of conversion in the form attached  hereto as Exhibit I (the  "Conversion
Notice"),  to the  Company  along with a printout  from  Bloomberg  L.P.  of the
weighted  average  prices over the  relevant  ten  trading  day period,  and (B)
surrender to a common carrier for delivery to the Company as soon as practicable
following such date, the original certificates representing the Preferred Shares
being converted (or an  indemnification  undertaking with respect to such shares
in the  case  of  their  loss,  theft  or  destruction)  (the  "Preferred  Stock
Certificates") and the originally executed Conversion Notice.

                  (ii)  Company's  Response.  Upon  receipt by the  Company of a
facsimile  copy of a Conversion  Notice,  the Company shall use its best efforts
to, by the end of the following business day send, via facsimile, a confirmation
of receipt of such Conversion Notice to such holder. Upon receipt by the Company
of the Preferred  Stock  Certificates  to be converted  pursuant to a Conversion
Notice,  together with the originally  executed  Conversion  Notice, the Company
shall,  on the third  business  day  following  the date of receipt of the faxed
Conversion  Notice (or the fourth  business day following the date of receipt of
the faxed  Conversion  Notice if  received  after  11:00 a.m.  local time of the
Company), provided that the Company receives the original documents listed above
prior to such  issue  date,  (I) issue and  surrender  to a common  carrier  for
overnight  delivery to the address as  specified  in the  Conversion  Notice,  a
certificate,  registered  in the name of the  holder  or its  designee,  for the
number of shares of Common Stock to which the holder shall be entitled,  or (II)
credit such aggregate number of shares of Common Stock to which the holder shall
be  entitled  to the  holder's  or  its  designee's  balance  account  with  The
Depository Trust Company.  If the number of Preferred Shares  represented by the
Preferred  Stock  Certificate(s)  submitted  for  conversion is greater than the
number of Preferred Shares being converted,  then the Company or Transfer Agent,
as the case may be,  shall,  as soon as  practicable  and in no event later than
three (3) business days after receipt of the Preferred Stock  Certificate(s) and
at its  own  expense,  issue  and  send  to the  holder  a new  Preferred  Stock
Certificate representing the number of Preferred Shares not converted.

                  (iii) Dispute  Resolution.  In the case of a dispute as to the
determination  of the Average Market Price or the arithmetic  calculation of the
Conversion  Rate,  the Company shall  promptly issue to the holder the number of
shares of Common Stock that is not disputed



the holder the number of shares of Common  Stock that is not  disputed and shall
submit the disputed  determinations or arithmetic calculations to the holder via
facsimile  within one (1)  business day of receipt of such  holder's  Conversion
Notice,  provided  that the holder has provided  the Company with the  Bloomberg
printout required in Section 2(e)(i).  If such holder and the Company are unable
to agree  upon the  determination  of the  Average  Market  Price or  arithmetic
calculation of the Conversion  Rate within one (1) business day of such disputed
determination or arithmetic  calculation being submitted to the holder, then the
Company  shall within one (1) business day submit via facsimile (A) the disputed
determination  of  the  Average  Market  Price  to  an  independent,   reputable
investment  bank or (B) the disputed  arithmetic  calculation  of the Conversion
Rate to its  independent,  outside  accountant.  The Company  shall use its best
efforts to cause the investment bank or the  accountant,  as the case may be, to
perform the determinations or calculations and notify the Company and the holder
of the  results no later than four (4)  business  days from the time it receives
the  disputed   determinations  or  calculations.   Such  investment  bank's  or
accountant's determination or calculation,  as the case may be, shall be binding
upon all parties absent manifest error.

                  (iv) Record Holder.  The person or persons entitled to receive
the shares of Common Stock issuable upon a conversion of Preferred  Shares shall
be treated for all  purposes  as the record  holder or holders of such shares of
Common Stock on the Conversion Date, provided the Company receives the Preferred
Stock Certificates within two (2) business days of the Conversion Notice.

                  (v) Company's Failure to Timely Convert.  If the Company shall
fail to issue and  deliver  to a courier  for  delivery  to a holder on a timely
basis as described in this Section  2(e)(ii),  a  certificate  for the number of
shares of Common  Stock to which  such  holder is  entitled  upon such  holder's
conversion of Preferred Shares or a new Preferred Stock Certificate representing
the number of shares of Common  Stock to which such holder is entitled  pursuant
to Section  2(e)(ii) except as provided in Section  4(a)(y),  in addition to all
other  available  remedies which such holder may pursue  hereunder and under the
Securities Purchase Agreement between the Company and the initial holders of the
Preferred   Shares   (the   "Securities    Purchase    Agreement")    (including
indemnification pursuant to Section 8 thereof), the Company shall pay additional
damages to such holder on each date such conversion is not timely effected in an
amount  equal to 1.0% of the product of (A) the number of shares of Common Stock
not issued to the holder on a timely  basis and to which such holder is entitled
and,  in the  event the  Company  has  failed to  deliver  the  Preferred  Stock
Certificate  to the holder on a timely basis pursuant to Section  2(e)(ii),  the
number of shares of Common  Stock  issuable  upon  conversion  of the  Preferred
Shares represented by such Preferred Stock Certificate,  and (B) the Closing Bid
Price of the Common Stock on the last possible date which the Company could have
issued such Common Stock and the Preferred  Stock  Certificate,  as the case may
be, to such holder without violating this Section 2(e).

            (f)  Taxes.  The  Company  shall pay any and all taxes  which may be
imposed  upon it with  respect to the issuance and delivery of Common Stock upon
the conversion of the Preferred Shares.

      (3)   Redemption at Option of Holders.

                   (a) Redemption Option Upon Major Transaction.  In addition to
all other rights of the holders of Preferred  Shares contained  herein,  after a
Major Transaction (as defined below), each holder of Preferred Shares shall have
the right,  at such holder's  option,  to require the Company to redeem all or a
portion of such holder's  Preferred  Shares at a price per Preferred Share equal
to



greater of (i) $1,250 and (ii) the  product of (A) the  Conversion  Rate at such
time and (B) the  Closing  Bid Price on the date of the public  announcement  of
such Major Transaction or the next date on which the exchange or market on which
the Common Stock is traded is open if such public announcement is made (X) after
12:00  p.m.,  Central  Time,  time on such  date or (Y) on a date on  which  the
exchange  or  market  on which the  Common  Stock is  traded  is closed  ("Major
Transaction Redemption Price").

            (b)  Redemption  Option Upon  Triggering  Event.  In addition to all
other  rights of the  holders of  Preferred  Shares  contained  herein,  after a
Triggering Event (as defined below),  each holder of Preferred Shares shall have
the right,  at such holder's  option,  to require the Company to redeem all or a
portion of such holder's  Preferred  Shares at a price per Preferred Share equal
to the greater of (i) $1,250 and (ii) the product of (A) the Conversion  Rate at
such time and (B) the Closing Bid Price  calculated  as of the date  immediately
preceding  such  Triggering  Event on which the  exchange or market on which the
Common  Stock is  traded  is open  ("Triggering  Event  Redemption  Price"  and,
collectively with "Major Transaction Redemption Price," the "Redemption Price").

            (c) "Major  Transaction".  A "Major  Transaction" shall be deemed to
have  occurred  at such  time as any of the  following  events  occur  with  the
recommendation and approval of the Company's Board of Directors:

                  (i) the consolidation,  merger, reorganization,  restructuring
or similar  transaction  of the Company with or into another  Person (other than
pursuant to a migratory  merger  effected solely for the purpose of changing the
jurisdiction of incorporation  of the Company or any such transaction  where the
Company is the survivor); or

                  (ii) the sale or transfer of  substantially  all of the assets
of the Company or all of its material subsidiaries or any similar transaction or
related transactions which effectively results in a sale of all or substantially
all of the assets of the Company and/or its subsidiaries (other than a public or
private  offering of Viral  Technologies,  Inc.  ("VTI") if the Company  owns at
least 50% of the voting  control and 50% of the  economic  interest in VTI after
such offering).

            (d) "Triggering Event". A "Triggering Event" shall be deemed to have
occurred at such time as any of the following events:

                  (i) the  Company's  notice to any holder of Preferred  Shares,
including by way of public  announcement,  at any time,  of its intention not to
comply with proper  requests for conversion of any Preferred  Shares into shares
of Common  Stock,  including due to any of the reasons set forth in Section 4(a)
below;

                  (ii) the Company, with the approval of its Board of Directors,
fails to continue to own,  directly or  indirectly,  all of the capital stock of
all of its material subsidiaries (other than due to a merger or consolidation of
any subsidiary  into the Company or a wholly-owned  subsidiary of the Company or
in the case of a public or private  offering  of VTI where the  Company  owns at
least  50% of the  voting  control  and  50% of  the  economic  interest  in VTI
following such Offering);

                  (iii) if for any  reason,  the  Company  fails to  perform  or
observe any, agreement or other provision  contained herein or in the Securities
Purchase Agreement or the Registration Rights Agreement, and such failure is not
cured within ten (10)  business  days after the Company has been notified of the
occurrence thereof, and such failure



has had, or could  reasonably be expected to have, a material  adverse effect on
(A)  the  financial  condition,   operating  results,  business,  properties  or
operation  of the  Company  and its  subsidiaries  taken  as a whole  or (B) the
Preferred Shares; or

                  (iv)  any   representation   or  warranty   contained  in  the
Securities  Purchase Agreement or the Registration  Rights Agreement is false or
misleading  on or as of the date made and  which  either  reflects  or has had a
material  adverse  effect on (A) the  financial  condition,  operating  results,
business,  properties or operations of the Company and its subsidiaries taken as
a whole or (B) the Preferred Shares.

            (e)   Mechanics  of   Redemption  at  Option  of  Buyer  Upon  Major
Transaction.  No  sooner  than 15 days  nor  later  than  10 days  prior  to the
consummation of a Major Transaction, but not prior to the public announcement of
such Major  Transaction,  the Company shall deliver  written  notice thereof via
facsimile and overnight  courier ("Notice of Major  Transaction") to each holder
of Preferred Shares. At any time after receipt of a Notice of Major Transaction,
the  holders  of  at  least  two-thirds  (2/3)  of  the  Preferred  Shares  then
outstanding  may  require the  Company to redeem all of the  holder's  Preferred
Shares then  outstanding by delivering  written notice thereof via facsimile and
overnight  courier  ("Notice  of  Redemption  at  Option  of  Buyer  Upon  Major
Transaction") to the Company, which Notice of Redemption at Option of Buyer Upon
Major  Transaction  shall indicate (i) the number of Preferred  Shares that such
holders  are  voting  in favor of  redemption  and  (ii)  the  applicable  Major
Transaction Redemption Price, as calculated pursuant to Section 3(a) above.

            (f)  Mechanics  of  Redemption  at Option of Buyer  Upon  Triggering
Event.  Within  three (3)  business  days after the  occurrence  of a Triggering
Event,  the Company  shall  deliver  written  notice  thereof via  facsimile and
overnight  courier  ("Notice of  Triggering  Event") to each holder of Preferred
Shares.  At any time after receipt of a Notice of Triggering  Event, the holders
of at least  two-thirds  (2/3) of the  Preferred  Shares  then  outstanding  may
require the Company to redeem all of the Preferred Shares by delivering  written
notice  thereof via facsimile and  overnight  courier  ("Notice of Redemption at
Option  of Buyer  Upon  Triggering  Event")  to the  Company,  which  Notice  of
Redemption  at Option of Buyer Upon  Triggering  Event  shall  indicate  (i) the
number of Preferred  Shares that such holders are voting in favor of  redemption
and (ii)  the  applicable  Triggering  Event  Redemption  Price,  as  calculated
pursuant to Section 3(b) above.

            (g) Payment of Redemption  Price.  Upon the  Company's  receipt of a
Notice(s) of Redemption at Option of Buyer Upon Major Transaction or a Notice(s)
of Redemption at Option of Buyer Upon Triggering Event, as the case may be, from
the  holders  of  at  least  two-thirds  (2/3)  of  the  Preferred  Shares  then
outstanding,  the Company shall  immediately  notify each holder by facsimile of
the Company's receipt of such requisite notices necessary to affect a redemption
and each holder of Preferred Shares shall thereafter promptly send such holder's
Preferred  Stock  Certificates  to be redeemed  to the  Company or its  Transfer
Agent. The Company shall deliver the applicable  Redemption Price to such holder
within 30 days after the Company's  receipt of the requisite notices required to
affect a redemption; provided that a holder's Preferred Stock Certificates shall
have been so delivered to the Company or its Transfer  Agent;  provided  further
that if the Company is unable to redeem all of the Preferred Shares, the Company
shall  redeem an amount  from each  holder  of  Preferred  Shares  equal to such
holder's  pro-rata amount (based on the number of Preferred  Shares held by such
holder relative to the number of Preferred Shares  outstanding) of all Preferred
Shares being redeemed.



If the Company  shall fail to redeem all of the Preferred  Shares  submitted for
redemption (other than pursuant to a dispute as to the arithmetic calculation of
the Redemption Price), in addition to any remedy such holder of Preferred Shares
may have under this  Certificate of  Designations  and the  Securities  Purchase
Agreement, the applicable Redemption Price payable in respect of such unredeemed
Preferred  Shares shall bear  interest at the rate of 1.75% per month  (prorated
for partial months) until paid in full or until voided as provided herein. Until
the Company pays such unpaid applicable Redemption Price in full to each holder,
holders of at least two-thirds  (2/3) of the Preferred Shares then  outstanding,
including shares of Preferred  Shares submitted for redemption  pursuant to this
Section 3 and for which the applicable Redemption Price has not been paid, shall
have  the  option  (the  "Void  Optional  Redemption  Option")  to,  in  lieu of
redemption,  require the  Company to  promptly  return to each holder all of the
Preferred  Shares that were  submitted for  redemption by such holder under this
Section 3 and for which the  applicable  Redemption  Price has not been paid, by
sending  written notice thereof to the Company via facsimile (the "Void Optional
Redemption Notice"). Upon the Company's receipt of such Void Optional Redemption
Notice(s) and prior to payment of the full applicable  Redemption  Price to each
holder, (i) the Notice(s) of Redemption at Option of Buyer Upon Triggering Event
or the Notice(s) of Redemption at Option of Buyer Upon Major Transaction, as the
case may be,  shall be null and void  with  respect  to those  Preferred  Shares
submitted for redemption and for which the applicable  Redemption  Price has not
been paid,  (ii) the  Company  shall  immediately  return any  Preferred  Shares
submitted to the Company by each holder for  redemption  under this Section 3(i)
and for which the applicable  Redemption  Price has not been paid, and (iii) the
Fixed  Conversion  Price of such returned  Preferred Shares shall be adjusted to
the lesser of (A) the Fixed  Conversion  Price as in effect on the date on which
the Void  Optional  Redemption  Notice(s is delivered to the Company and (B) the
lowest  Closing Bid Price  during the period  beginning on the date on which the
Notice(s)  of  Redemption  of  Option of Buyer  Upon  Major  Transaction  or the
Notice(s) of Redemption at Option of Buyer Upon  Triggering  event,  as the case
may be, is  delivered  to the  Company  and ending on the date on which the Void
Optional  Redemption  Notice(s) is delivered  to the Company;  provided  that no
adjustment  shall be made if such adjustment  would result in an increase of the
Fixed Conversion  Price then in effect.  Notwithstanding  the foregoing,  in the
event of a  dispute  as to the  determination  of the  Closing  Bid Price or the
arithmetic  calculation of the Redemption  Price, such dispute shall be resolved
pursuant to Section  2(c)(iii)  above with the term  "Closing  Bid Price"  being
substituted for the term "Average Market Price" and the term "Redemption  Price"
being substituted for the term "Conversion  Rate." Payments provided for in this
Section 3 shall have  priority to payments to other  stockholders  in connection
with a Major Transaction.

            (4)   Inability to Fully Convert.

                  (a) Holder's Option if Company Cannot Fully Convert.  If, upon
the Company's receipt of a Conversion  Notice,  the Company can not issue shares
of Common Stock registered for resale under the  Registration  Statement for any
reason, including,  without limitation,  because the Company (x) does not have a
sufficient  number of shares of Common Stock  authorized and  available,  (y) is
otherwise  prohibited by applicable  law or by the rules or  regulations  of any
stock  exchange,   interdealer   quotation   system  or  other   self-regulatory
organization  with  jurisdiction  over the Company or its Securities,  including
without  limitation the Common Share Limit, from issuing all of the Common Stock
which is to be issued to a holder of Preferred  Shares  pursuant to a Conversion
Notice or (z)  fails to have a  sufficient  number  of  shares  of Common  Stock
registered for resale under the Registration  Statement,  then the Company shall
issue as many shares of Common Stock as it is able to issue in  accordance  with
such  holder's  Conversion  Notice and pursuant to Section 2(e) above and,  with
respect to the unconverted Preferred Shares, the holder, solely at such holder's
option, can elect to:

                        (i)   require  the  Company to redeem  from such
holder  those  Preferred  Shares for which the Company is unable to issue Common
Stock  in  accordance   with  such  holder's   Conversion   Notice   ("Mandatory
Redemption") at a price per Preferred Share (the "Mandatory  Redemption  Price")
equal to the Redemption Price as of such Conversion Date;




                        (ii)  if  the   Company's   inability  to  fully
convert  Preferred  Shares is pursuant  to Section  4(a)(z)  above,  require the
Company  to issue  restricted  shares of Common  Stock in  accordance  with such
holder's Conversion Notice and pursuant to Section 2(e) above;

                        (iii) void its  Conversion  Notice and retain or
have returned,  as the case may be, the nonconverted  Preferred Shares that were
to be converted pursuant to such holder's Conversion Notice.

                  (b) Mechanics of  Fulfilling  Holder's  Election.  The Company
shall  immediately  send via  facsimile  to a holder of Preferred  Shares,  upon
receipt of a facsimile copy of a Conversion Notice from such holder which cannot
be fully satisfied as described in Section 4(a) above, a notice of the Company's
inability to fully satisfy such holder's  Conversion  Notice (the  "Inability to
Fully Convert  Notice").  Such  Inability to Fully Convert Notice shall indicate
(i) the  reason  why the  Company  is  unable  to fully  satisfy  such  holder's
Conversion Notice, (ii) the number of Preferred Shares which cannot be converted
and (iii) the applicable  Mandatory  Redemption  Price.  Such holder must within
five (5)  business  days of receipt of such  Inability to Fully  Convert  Notice
deliver  written  notice via  facsimile  to the Company  ("Notice in Response to
Inability to Convert") of its election pursuant to Section 4(a) above.

                  (c) Payment of Redemption Price. If such holder shall elect to
have its shares redeemed  pursuant to Section  4(a)(i) above,  the Company shall
pay the  Mandatory  Redemption  Price in cash to such holder  within thirty (30)
days of the Company's receipt of the holder's Notice in Response to Inability to
Convert.  If the Company shall fail to pay the applicable  Mandatory  Redemption
Price to such holder on a timely  basis as described in this Section 4(c) (other
than pursuant to a dispute as to the determination of the arithmetic calculation
of the  Redemption  Price),  in addition to any remedy such holder of  Preferred
Shares  may have under  this  Certificate  of  Designations  and the  Securities
Purchase Agreement,  such unpaid amount shall bear interest at the rate of 1.75%
per month  (prorated  for  partial  months)  until paid in full.  Until the full
Mandatory  Redemption Price is paid in full to such holder, such holder may void
the Mandatory  Redemption with respect to those  Preferred  Shares for which the
full  Mandatory  Redemption  Price  has not been  paid  and  receive  back  such
Preferred Shares. Notwithstanding the foregoing, if the Company fails to pay the
applicable  Mandatory  Redemption Price within such thirty (30) days time period
due to a dispute as to the  determination  of the arithmetic  calculation of the
Redemption  Price,  such dispute shall be resolved pursuant to Section 2(e)(iii)
above  with  the  term  "Redemption   Price"  being  substituted  for  the  term
"Conversion Rate".

                  (d)  Pro-rata  Conversion  and  Redemption.  In the  event the
Company  receives a  Conversion  Notice  from more than one holder of  Preferred
Shares on the same day and the Company can convert and redeem some, but not all,
of the  Preferred  Shares  pursuant to this Section 4, the Company shall convert
and redeem  from each holder of  Preferred  Shares  electing  to have  Preferred
Shares  converted  and  redeemed at such time an amount  equal to such  holder's
pro-rata  amount  (based on the number of  Preferred  Shares held by such holder
relative to the number of Preferred Shares  outstanding) of all Preferred Shares
being converted and redeemed at such time.

            (5)  Reissuance  of  Certificates.  In the event of a conversion  or
redemption  pursuant to this Certificate of Designations of less than all of the
Preferred Shares represented by a particular  Preferred Stock  Certificate,  the
Company  shall  promptly  cause to be issued and delivered to the holder of such
Preferred  Shares a  preferred  stock  certificate  representing  the  remaining
Preferred Shares which have not been so converted or redeemed.




            (6) Reservation of Shares.  The Company shall, so long as any of the
Preferred  Shares  are  outstanding,  reserve  and  keep  available  out  of its
authorized  and unissued  Common Stock,  solely for the purpose of effecting the
conversion  of the  Preferred  Shares,  such number of shares of Common Stock as
shall from time to time be  sufficient  to effect the  conversion  of all of the
Preferred Shares then outstanding;  provided that the number of shares of Common
Stock so reserved  shall at no time be less than 200% of the number of shares of
Common  Stock  for  which  the  Preferred  Shares  are at any time  convertible;
provided further that such shares of Common Stock so reserved shall be allocated
for issuance upon  conversion of Preferred  Shares pro rata among the holders of
Preferred  Shares  based on the number of  Preferred  Shares held by such holder
relative to the total number of then outstanding Preferred Shares.

            (7) Voting Rights.  Holders of Preferred Shares shall have no voting
rights,  except as  required  by law,  including  but not limited to the General
Corporation  Law of the State of  Colorado,  and as  expressly  provided in this
Certificate of Designations.

            (8)  Liquidation,  Dissolution,  Winding-Up.  In  the  event  of any
voluntary or involuntary liquidation,  dissolution or winding up of the Company,
the holders of the Preferred  Shares shall be entitled to receive in cash out of
the assets of the Company,  whether from capital or from earnings  available for
distribution  to its  stockholders  (the "Preferred  Funds"),  before any amount
shall be paid to the holders of any of the  capital  stock of the Company of any
class junior in rank to the Preferred Shares in respect of the preferences as to
the distributions and payments on the liquidation, dissolution and winding up of
the Company,  an amount per Preferred Share equal to the sum of $1,000 (such sum
being referred to as the "Liquidation  Value");  provided that, if the Preferred
Funds are  insufficient  to pay the full amount due to the holders of  Preferred
Shares and holders of shares of other  classes or series of  preferred  stock of
the Company that are of equal rank with the  Preferred  Shares as to payments of
Preferred Funds (the "Pari Passu Shares"),  then each holder of Preferred Shares
and Pari Passu Shares shall receive a percentage of the Preferred Funds equal to
the full  amount of  Preferred  Funds  payable to such  holder as a  liquidation
preference,  in accordance with their  respective  Certificate of  Designations,
Preferences  and Rights,  as a percentage of the full amount of Preferred  Funds
payable to all holders of Preferred  Shares and Pari Passu Shares.  The purchase
or redemption by the Company of stock of any class,  in any manner  permitted by
law,  shall  not,  for  the  purposes  hereof,  be  regarded  as a  liquidation,
dissolution or winding up of the Company. Neither the consolidation or merger of
the  Company  with or into any other  Person,  nor the sale or  transfer  by the
Company of less than  substantially  all of its assets,  shall, for the purposes
hereof, be deemed to be a liquidation, dissolution or winding up of the Company.
No holder of  Preferred  Shares  shall be entitled  to receive any amounts  with
respect thereto upon any  liquidation,  dissolution or winding up of the Company
other than the amounts provided for herein.

            (9)  Preferred  Rank.  All shares of Common Stock shall be of junior
rank to all Preferred  Shares in respect to the preferences as to  distributions
and payments upon the  liquidation,  dissolution  and winding up of the Company.
The rights of the shares of Common Stock shall be subject to the preferences and
relative  rights of the  Preferred  Shares.  Without the prior  express  written
consent of the holders of not less than two-thirds (2/3) of the then outstanding
Preferred Shares, the Company shall not hereafter  authorize or issue additional
or other capital  stock that is of senior or equal rank to the Preferred  Shares
in  respect  of the  preferences  as to  distributions  and  payments  upon  the
liquidation,  dissolution  and  winding  up of the  Company.  Without  the prior
express written consent of the holders of not less than two-thirds  (2/3) of the
then outstanding  Preferred Shares, the Company shall not hereafter authorize or
make any amendment to the Company's  Certificate of Incorporation or bylaws,  or
file any  resolution  of the board of directors of the Company with the Delaware
Secretary of State  containing any provisions,  which would adversely  affect or
otherwise impair the rights or relative priority of the holders of the Preferred
Shares  relative to the holders of the Common  Stock or the holders of any other
class of  capital  stock.  In the event of the  merger or  consolidation  of the
Company with or into another  corporation,  the Preferred  Shares shall maintain
their relative powers,  designations and preferences  provided for herein and no
merger shall result inconsistent therewith.

            (10)  Restriction  on Redemption  and Cash Dividends with respect to
Other Capital  Stock.  Until all of the Preferred  Shares have been converted or
redeemed as provided  herein,  the Company  shall not,  directly or  indirectly,
redeem, or declare or pay any cash dividend or distribution on, its Common Stock
without  the prior  express  written  consent  of the  holders  of not less than
two-thirds (2/3) of the then outstanding Preferred Shares.

            (11)  Limitation on Number of Conversion  Shares.  The Company shall
not be obligated  to issue,  in the  aggregate,  more than  2,243,782  shares of
Common Stock (such amount to be proportionately and equitably adjusted from time
to time in the event of stock splits,  stock  dividends,  combinations,  reverse
stock  splits,  reclassification,  capital  reorganizations  and similar  events
relating to the Common Stock) (the "Common Share Limit") upon  conversion of the
Preferred Shares, if issuance of a larger number of shares of Common Stock would
constitute a breach of the Company's  obligations under the rules or regulations
of The American Stock  Exchange or any other  principal  securities  exchange or
market upon which the Common Stock becomes traded.  The Common Share Limit shall
be allocated  among the holders of Preferred  Shares pro rata based on the total
number of Preferred Shares issued on the Closing Date. The remaining  portion of
the Common Share Limit  attributable to any holder of Preferred  Shares,  all of
whose Preferred Shares has been converted or redeemed,  shall be allocated among
the  remaining  holders  of  Preferred  Shares  pro rata  based on the number of
Preferred Shares then outstanding.

            (12) Vote to Change the Terms of Preferred  Shares.  The affirmative
vote at a meeting duly called for such purpose or the written  consent without a
meeting,  of  the  holders  of not  less  than  two-thirds  (2/3)  of  the  then
outstanding  Preferred  Shares,  shall  be  required  for  any  change  to  this
Certificate of Designations or the Company's  Certificate of Incorporation which
would  amend,  alter,  change  or  repeal  any  of  the  powers,   designations,
preferences and rights of the Preferred Shares.

            (13) Lost or Stolen  Certificates.  Upon  receipt by the  Company of
evidence  satisfactory  to  the  Company  of the  loss,  theft,  destruction  or
mutilation  of any  Preferred  Stock  Certificates  representing  the  Preferred
Shares,  and, in the case of loss, theft or destruction,  of any indemnification
undertaking  by the holder to the Company and, in the case of  mutilation,  upon
surrender and  cancellation of the Preferred Stock  Certificate(s),  the Company
shall execute and deliver new preferred stock  certificate(s)  of like tenor and
date;  provided,  however,  the  Company  shall  not be  obligated  to  re-issue
preferred  stock  certificates  if the  holder  contemporaneously  requests  the
Company to convert such Preferred Shares into Common Stock.

      IN  WITNESS   WHEREOF,   the  Company  has  caused  this   Certificate  of
Designations to be signed by Geert Kersten,  its Chief Executive Officer,  as of
the 22nd day of December 1997.
