                                    WARRANT

Warrant No.[   ]                                         Dated: March 21, 2000


      Cel-Sci  Corporation,  a  Colorado  corporation  (the  "Company"),  hereby
certifies that, for value received,  [ ] or its registered and permitted assigns
("Holder"), is entitled,  subject to the terms set forth below, to purchase from
the Company the total number of shares of Common Stock, $.01 par value per share
(the "Common Stock"), of the Company (each such share, a "Warrant Share" and all
such shares,  the  "Warrant  Shares")  calculated  pursuant to Section 3 of this
Warrant  (subject to  adjustment  for certain  events as set forth herein) at an
exercise  price  equal to $.001  per  share  (as  adjusted  from time to time as
provided in Section 8, the "Exercise  Price"),  from the date hereof through and
including  the 30th Trading Day following  March 21, 2003 (such later date,  the
"Expiration  Date"), and subject to the following terms and conditions  (certain
terms used herein are defined in Exhibit A attached hereto):

      1. Registration of Warrant. The Company shall register this Warrant,  upon
records  to be  maintained  by  the  Company  for  that  purpose  (the  "Warrant
Register"),  in the name of the  record  Holder  hereof  from time to time.  The
Company may deem and treat the registered Holder of this Warrant as the absolute
owner hereof for the purpose of any exercise  hereof or any  distribution to the
Holder,  and for all other  purposes,  and the Company  shall not be affected by
notice to the contrary.

      2.  Registration of Transfers.  The Company shall register the transfer of
any portion of this  Warrant in the Warrant  Register,  upon  surrender  of this
Warrant,  with the Form of Assignment attached hereto duly completed and signed,
to the Transfer Agent or to the Company at the address  specified in Section 13.
Upon any such registration or transfer,  a new warrant to purchase Common Stock,
in  substantially  the  form of this  Warrant  (any  such  new  warrant,  a "New
Warrant"), evidencing the portion of this Warrant so transferred shall be issued
to the  transferee and a New Warrant  evidencing  the remaining  portion of this
Warrant not so transferred,  if any, shall be issued to the transferring Holder.
The acceptance of the New Warrant by the transferee  thereof shall be deemed the

<PAGE>

acceptance of such  transferee of all of the rights and  obligations of a holder
of this  Warrant and of the original  holder of this Warrant  under the Purchase
Agreement (as defined in Exhibit A).

      3.    Duration, Vesting and Exercise of Warrant.

(a) The vesting of the Warrant  Shares which the Holder may acquire  pursuant to
this Warrant shall occur on the dates (each a "Vesting  Date") set forth in this
Section 3. On each such date,  this Warrant  shall vest with respect to a number
of Warrant  Shares  calculated  pursuant to Section 3(b). The first vesting date
(the "First Vesting Date") shall be the 360th day following the Closing Date (as
defined in Exhibit  A). An  additional  Vesting  Date shall  occur on each sixth
month  anniversary  of the First  Vesting Date through and  including  March 16,
2003.  The Company and the Holder  agree that the number of Warrant  Shares that
the Holder may acquire  hereunder  may only be increased,  and never  decreased,
from and after the First Vesting Date.

            (b) Except as  otherwise  set forth in this  Warrant,  this  Warrant
shall vest and become exercisable on a Vesting Date as described in Section 3(a)
for the number of Warrant  Shares  calculated in  accordance  with the following
formula:

                                     [(C x PA) / A] - C

          C           = Shares  (as  defined in Exhibit A) held by the Holder on
                      the Vesting Date less any hedged Shares.
          PA          = The  Adjustment  Price  from the  immediately  preceding
                      Vesting Date or, with respect to the First  Vesting  Date,
                      $6.52   (which   number  shall  be  subject  to  equitable
                      adjustments for stock splits,  recombinations  and similar
                      events) (the "Initial Closing Price").
          A           = "Adjustment  Price," which is equal to the lesser of (y)
                      $6.52,  or (z) the  average  of the 10  lowest  Per  Share
                      Market  Values  during  the 30  Trading  Days  immediately
                      preceding the Vesting Date.

          If the number  calculated in accordance with the foregoing  formula is
zero or a  negative  number,  no Warrant  Shares  shall vest (in the case of the
First Vesting Date) or no  additional  Warrant  Shares will vest (in the case of
any  subsequent  Vesting  Dates) for such Vesting Date. In addition,  the Holder
shall not be obligated to transfer any shares of Common Stock to the Company and
the number  Warrant Shares  exercisable  hereunder  which shall have  previously
vested will not decrease.

            (c) The  occurrence  of any of the  following  events  shall also be
deemed a Vesting Date under this Warrant.  The  calculation set forth in Section
3(b) shall be made on the date of the occurrence of such events and  "Adjustment
Price"  shall be deemed to mean the  average of the 10 lowest  Per Share  Market
Values  during  the 30  Trading  Days  immediately  preceding  the  date of such
occurrence:

<PAGE>

(i)  upon the occurrence of any of (i) an  acquisition  after the date hereof by
     an individual or legal entity or "group" (as described in Rule  13d-5(b)(1)
     promulgated  under the  Securities  Exchange  Act of 1934,  as amended (the
     "Exchange  Act"))  of in  excess  of 1/3 of the  voting  securities  of the
     Company,  (ii) a  replacement  of more than  one-half of the members of the
     Company's board of directors which is not approved by those individuals who
     are members of the board of directors on the date hereof in one or a series
     of  related  transactions,  (iii) the  merger of the  Company  with or into
     another entity,  consolidation or sale of all or  substantially  all of the
     assets of the  Company in one or a series of related  transactions,  unless
     following such  transaction or series of  transactions,  the holders of the
     Company's  securities prior to the first such transaction  continue to hold
     at least 2/3 of the securities of the surviving  entity or acquirer of such
     assets or (iv) the  execution  by the Company of an  agreement to which the
     Company is a party or by which it is bound, providing for any of the events
     set forth above in (i), (ii) or (iii);

(ii) immediately  prior to an  assignment  by the  Company  for the  benefit  of
     creditors or  commencement of a voluntary case under Title 11 of the United
     States Code, or an entering  into of an order for relief in an  involuntary
     case under Title 11 of the United  States Code,  or adoption by the Company
     of a plan of liquidation or dissolution;

(iii)five (5) Business Days prior to the proposed  consummation  with respect to
     the  Company of a "Rule 13e-3  transaction"  as defined in Rule 13e-3 under
     the Exchange Act (or, if necessary,  such earlier date as the Company shall
     determine  in good faith to be  required in order for the Holder to be able
     to participate in such  transaction),  it being agreed that the Holder will
     receive actual notice of the 13e-3  Statement  filed with the Commission on
     the date filed and actual notice of the date of  acceleration  hereunder no
     later than such date;

(iv) The Common  Stock fails to be listed or quoted for trading on the AMEX or a
     Subsequent  Market for a period of five (5) Trading Days (which need not be
     consecutive Trading Days);

(v)  A holder of Registrable  Securities (as defined in the Registration  Rights
     Agreement)  is not  permitted  to sell  Registrable  Securities  under  the
     Underlying  Shares  Registration  Statement  for any reason for five (5) or
     more Trading Days (whether or not consecutive); or

(vi) The Company shall fail or default in the timely performance of any material
     obligation  under the  Transaction  Documents  and such  failure or default
     shall  continue  uncured for a period of five (5)  Business  Days after the
     date on which  notice of such  failure  or  default  is first  given to the
     Company (it being  understood  that no prior notice need be provided in the
     case of defaults which cannot reasonably be cured within a 5-day period).

        (d)     Additional Vesting Dates shall also occur on such dates, if any,
on which the Company or any subsidiary thereof, shall, except in connection with
(A) the  granting  of shares  of Common  Stock or stock  options  to  employees,
officers and directors pursuant to any stock bonus plan or employee benefit plan
heretofore  or  hereinafter  duly  adopted by the  Company  and (B) a  Strategic
Transaction  (as  defined  below),  issue  shares  of  Common  Stock or  rights,
warrants,  options  or other  securities  or debt  that is  convertible  into or

<PAGE>

exchangeable for shares of Common Stock ("Common Stock Equivalents"),  entitling
any person or entity to acquire shares of Common Stock at a price per share less
than the  Initial  Closing  Price (if the holder of the  Common  Stock or Common
Stock  Equivalent so issued shall at any time,  whether by operation of purchase
price adjustments, reset provisions,  floating conversion,  exercise or exchange
prices or otherwise, or due to warrants,  options or rights issued in connection
with such  issuance,  be entitled to receive  shares of Common  Stock at a price
less than the  Initial  Closing  Price,  such  issuance  shall be deemed to have
occurred for less than the Initial  Closing  Price),  either in one  transaction
resulting in gross  proceeds to the Company in excess of  $1,000,000 or a series
of  transactions  resulting in aggregate gross proceeds to the Company in excess
of $1,000,000  (any such  transaction or series of  transactions,  a "Discounted
Offering" and the date of a Discounted  Offering, a "Discounted Offering Date"),
then in addition to any other  vesting of Warrant  Shares  pursuant to the terms
hereof,  on a Discounted  Offering Date, this Warrant shall vest with respect to
the number of Warrant Shares calculated in accordance with the formula set forth
below:

                                    [(C x I) / DOAP] - C

          C =   Shares  held by the Holder on the Vesting Date less any
                hedged Shares
          I  =  Initial  Closing  Price
       DOAP  =  "Discounted   Offering Adjustment Price," equal to the lessor of
                (x) $6.52, (y) the average of the Per Share Market Values for
                 the 10 trading days  immediately  preceding the Discounted
                 Offering  Date, or (z) the price per share of Common Stock
                 or Common  Stock  Equivalent  (as the case may be)  issued
                 pursuant to the Discounted  Offering  (taking into account
                 all actual or implied discounts).

            If the number calculated in accordance with the foregoing formula is
zero or a negative  number,  no Warrant  Shares shall vest pursuant to the terms
hereof and the Holder  shall not be  obligated  to transfer any shares of Common
Stock to the Company.  For purposes of this Section,  a "Strategic  Transaction"
shall mean a transaction or  relationship  in which the Company issues shares of
Common  Stock to an entity  which is,  itself or through  its  subsidiaries,  an
operating  company in a business  related to the  business of the Company and in
which the Company  receives  material  benefits in addition to the investment of
funds,  but shall not  include a  transaction  in which the  Company  is issuing
securities primarily for the purpose of raising capital.


            (e)  Subject  to  Sections  3(a)  and  (b),  this  Warrant  shall be
exercisable by the  registered  Holder on any Business Day before 5:00 P.M., New
York City time, at any time and from time to time on or after the date hereof to
and  including  the  Expiration  Date.  At 5:00 P.M.,  New York City time on the
Expiration  Date, the portion of this Warrant not exercised  prior thereto shall
be and become void and of no value.

            (f)  Subject  to  Sections  3(a)  and  (b),  this  Warrant  shall be
exercisable,  either in its entirety or, from time to time, for a portion of the
number of Warrant  Shares.  If less than all of the Warrant  Shares which may be
purchased  under this Warrant are exercised at any time, the Company shall issue
or cause to be issued,  at its expense,  a New Warrant  evidencing  the right to
purchase the remaining  number of Warrant  Shares for which no exercise has been
evidenced by this Warrant.

<PAGE>

      4.    Delivery of Warrant Shares.

            (a) Upon  surrender  of this  Warrant,  with the Form of Election to
Purchase  attached  hereto  duly  completed  and  signed,  to the Company at its
address  for notice set forth in  Section  13 and upon  payment of the  Exercise
Price  multiplied  by the number of Warrant  Shares  that the Holder  intends to
purchase hereunder,  in the manner provided  hereunder,  all as specified by the
Holder in the Form of Election to Purchase,  the Company shall  promptly (but in
no event later than four (4) Trading Days after the Date of Exercise (as defined
herein))  issue or cause to be issued and cause to be  delivered  to or upon the
written  order  of the  Holder  and in such  name or  names  as the  Holder  may
designate,  a certificate  for the Warrant  Shares  issuable upon such exercise,
free of  restrictive  legends,  except when an  Underlying  Shares  Registration
Statement  is  not  then  effective  and  the  Warrant  Shares  are  not  freely
transferable  pursuant to Rule 144 promulgated under the Securities Act of 1933,
as amended (the  "Securities  Act").  Any person so  designated by the Holder to
receive  Warrant  Shares shall be deemed to have become holder of record of such
Warrant  Shares as of the Date of Exercise of this Warrant.  The Company  shall,
upon  request  of the  Holder,  if  available,  use its best  efforts to deliver
Warrant Shares hereunder electronically through the Depository Trust Corporation
or another  established  clearing  corporation  performing similar functions.  A
"Date of Exercise"  means the date on which the Company  shall have received (i)
this Warrant (or any New Warrant,  as applicable),  with the Form of Election to
Purchase  attached  hereto  (or  attached  to such  New  Warrant)  appropriately
completed and duly signed, and (ii) payment of the Exercise Price for the number
of Warrant Shares to be purchased so indicated by the Holder hereof.

            (b) If the  Company  fails to deliver to the Holder to an address in
the United States  certificate or certificates  representing  the Warrant Shares
pursuant  to Section  4(a) by the  fourth  (4th)  Trading  Day after the Date of
Exercise,  the Company shall pay to such Holder, in cash, as liquidated  damages
and not as a penalty,  the lesser of (A) $5,000 and (B) $0.10 per Warrant  Share
for which a certificate was not timely  delivered  pursuant to the terms hereof,
for each day after such fourth  (4th)  Trading Day until such  certificates  are
delivered.  Nothing  herein  shall  limit the  Holder's  right to pursue  actual
damages for the Company's failure to deliver certificates representing shares of
Common Stock upon  exercise  within the period  specified  herein and the Holder
shall have the right to pursue all remedies  available to it at law or in equity
including,   without  limitation,   a  decree  of  specific  performance  and/or
injunctive relief. The exercise of any such rights shall not prohibit the Holder
from seeking to enforce  damages  pursuant to any other Section  hereof or under
applicable law.

            (c) In addition to any other rights available to the Holder,  if the
Company fails to deliver to the Holder certificate or certificates  representing
the Warrant  Shares  pursuant to Section  4(a) by the fourth  (4th)  Trading Day
after the Date of  Exercise,  and if after such  fourth  (4th)  Trading  Day the
Holder purchases (in an open market  transaction or otherwise)  shares of Common
Stock to deliver in  satisfaction  of a sale by the Holder of the Warrant Shares
which the Holder anticipated receiving upon such exercise (a "Buy-In"), then the
Company shall pay (1) in cash to the Holder the amount by which (x) the Holder's
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the

<PAGE>

number of Warrant  Shares that the Company was  required to deliver  pursuant to
Section 4(b) to the Holder in  connection  with the exercise at issue by (B) the
Per Share Market Value on the Date of Exercise and (2) deliver to the Holder the
number of shares of Common  Stock that would  have been  issued had the  Company
timely complied with its exercise and delivery  obligations  under Section 4(b).
For example,  if the Holder purchases Common Stock having a total purchase price
of $11,000 to cover a Buy-In with respect to an attempted  exercise of shares of
Common Stock with a market price on the date of exercise which totaled  $10,000,
under clause (A) of the  immediately  preceding  sentence  the Company  shall be
required to pay the Holder $1,000.  The Holder shall provide the Company written
notice indicating the amounts payable to the Holder in respect of the Buy-In.

            (d) The Company's obligations to issue and deliver Warrant Shares in
accordance with the terms hereof are absolute and unconditional, irrespective of
any action or inaction by the Holder to enforce the same,  any waiver or consent
with respect to any provision  hereof,  the recovery of any judgment against any
Person  or  any  action  to  enforce  the  same,  or any  setoff,  counterclaim,
recoupment,  limitation or  termination,  or any breach or alleged breach by the
Holder or any other Person of any  obligation to the Company or any violation or
alleged violation of law by the Holder or any other Person,  and irrespective of
any other  circumstance  which  might  otherwise  limit such  obligation  of the
Company to the Holder in connection with the issuance of Warrant Shares.  If the
Company  breaches its obligations  under this Warrant,  then, in addition to any
other  liabilities the Company may have hereunder and under  applicable law, the
Company  shall pay or reimburse the Holder on demand for all costs of collection
and enforcement (including reasonable attorneys fees and expenses).

      5.  Payment of Taxes.  The Company  will pay all  documentary  stamp taxes
attributable  to the  issuance  of  Warrant  Shares  upon the  exercise  of this
Warrant;  provided,  however,  that the Company shall not be required to pay any
tax which may be payable in respect of any transfer involved in the registration
of any  certificates for Warrant Shares or Warrants in a name other than that of
the Holder. The Holder shall be responsible for all other tax liability that may
arise as a result of holding or transferring  this Warrant or receiving  Warrant
Shares upon exercise hereof.

      6. Replacement of Warrant.  If this Warrant is mutilated,  lost, stolen or
destroyed,  the  Company  shall  issue or cause to be  issued  in  exchange  and
substitution for and upon  cancellation  hereof,  or in lieu of and substitution
for this Warrant,  a New Warrant,  but only upon receipt of evidence  reasonably
satisfactory to the Company of such loss, theft or destruction and customary and
reasonable  indemnity,  if  requested.  Applicants  for a New Warrant under such
circumstances  shall also  comply  with such other  reasonable  regulations  and
procedures and pay such other reasonable charges as the Company may prescribe.

      7.  Reservation of Warrant Shares.  The Company  covenants that it will at
all times reserve and keep  available out of the aggregate of its authorized but
unissued  Common  Stock,  solely for the purpose of enabling it to issue Warrant
Shares upon exercise of this Warrant as herein  provided,  the number of Warrant
Shares which are then issuable and deliverable  upon the exercise of this entire
Warrant,  free from preemptive  rights or any other actual  contingent  purchase
rights of persons other than the Holder (taking into account the adjustments and
restrictions  of Section 8). The Company  covenants that all Warrant Shares that
shall be so issuable and deliverable shall, upon issuance and the payment of the
applicable  Exercise  Price in  accordance  with the terms  hereof,  be duly and
validly authorized, issued and fully paid and nonassessable.

<PAGE>

      8. Certain  Adjustments.  The Exercise  Price and number of Warrant Shares
issuable upon  exercise of this Warrant are subject to  adjustment  from time to
time as set forth in this  Section.  Upon each such  adjustment  of the Exercise
Price  pursuant  to this  Section,  the  Holder  shall  thereafter  prior to the
Expiration  Date be entitled to purchase,  at the Exercise Price  resulting from
such  adjustment,  the number of Warrant  Shares  obtained  by  multiplying  the
Exercise Price in effect  immediately  prior to such adjustment by the number of
Warrant  Shares  issuable  upon  exercise of this Warrant  notwithstanding  such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

            (i) If the Company,  at any time while this Warrant is  outstanding,
(i) shall pay a stock dividend (except  scheduled  dividends paid on outstanding
preferred  stock as of the date hereof which contain a stated  dividend rate) or
otherwise make a distribution or  distributions on shares of its Common Stock or
on any other  class of capital  stock  payable in shares of Common  Stock,  (ii)
subdivide  outstanding shares of Common Stock into a larger number of shares, or
(iii)  combine  outstanding  shares of  Common  Stock  into a smaller  number of
shares,  the  Exercise  Price  shall be  multiplied  by a fraction  of which the
numerator  shall be the  number of shares of Common  Stock  (excluding  treasury
shares, if any) outstanding before such event and of which the denominator shall
be the number of shares of Common  Stock  (excluding  treasury  shares,  if any)
outstanding after such event. Any adjustment made pursuant to this Section shall
become  effective  immediately  after the record date for the  determination  of
stockholders  entitled to receive such dividend or distribution and shall become
effective  immediately  after the effective date in the case of a subdivision or
combination, and shall apply to successive subdivisions and combinations.

            (ii) In case of any  reclassification  of the  Common  Stock  or any
compulsory  share exchange  pursuant to which the Common Stock is converted into
other  securities,  cash or  property,  then the  Holder  shall  have the  right
thereafter  to  exercise  this  Warrant  only into the shares of stock and other
securities  and  property  receivable  upon or deemed to be held by  holders  of
Common Stock following such  reclassification,  transfer or share exchange,  and
the  Holder  shall be  entitled  upon  such  event to  receive  such  amount  of
securities or property  equal to the amount of Warrant  Shares such Holder would
have been entitled to had such Holder exercised this Warrant  immediately  prior
to such  reclassification,  transfer  or share  exchange.  The terms of any such
consolidation, merger, sale, transfer or share exchange shall include such terms
so as to continue to give to the Holder the right to receive the  securities  or
property set forth in this Section  8(b) upon any  exercise  following  any such
reclassification, transfer or share exchange.

            (iii) If the Company, at any time while this Warrant is outstanding,
shall  distribute  to all  holders  of Common  Stock (and not to holders of this
Warrant)  evidences  of its  indebtedness  or assets or  rights or  warrants  to
subscribe for or purchase any security  (excluding those referred to in Sections
8(i),  (ii) and  (iv)),  then in each  such  case the  Exercise  Price  shall be
determined by multiplying the Exercise Price in effect  immediately prior to the
record date fixed for  determination  of  stockholders  entitled to receive such
distribution by a fraction of which the denominator  shall be the Exercise Price
determined  as of the record date  mentioned  above,  and of which the numerator

<PAGE>

shall be such Exercise Price on such record date less the then fair market value
at such record date of the portion of such assets or evidence of indebtedness so
distributed applicable to one outstanding share of Common Stock as determined by
the Company's  independent  certified public accountants that regularly examines
the financial statements of the Company (an "Appraiser").

            (iv) In case of any (1) merger or  consolidation of the Company with
or into another Person,  or (2) sale by the Company of more than one-half of the
assets of the  Company (on a market  value  basis) in one or a series of related
transactions,  or (3) tender or other offer or exchange  (whether by the Company
or another  Person)  pursuant to which  holders of Common Stock are permitted to
tender or exchange their shares for other securities, stock, cash or property of
the Company or another Person;  then the Holder shall have the right  thereafter
to (A) exercise this Warrant for the shares of stock and other securities,  cash
and  property  receivable  upon or deemed to be held by holders of Common  Stock
following such merger,  consolidation  or sale, and the Holder shall be entitled
upon  such  event or  series  of  related  events  to  receive  such  amount  of
securities,  cash and property as the Common Stock for which this Warrant  could
have been exercised  immediately  prior to such merger,  consolidation  or sales
would have been entitled, (B) in the case of a merger or consolidation,  require
the  surviving  entity to issue to the Holder a warrant  entitling the Holder to
acquire  shares of such entity's  common  stock,  which warrant shall have terms
identical mutatis mutandis  (including with respect to exercise) to the terms of
this Warrant and shall be entitled to all of the rights and privileges set forth
herein and the agreements  pursuant to which this Warrant was issued (including,
without limitation,  as such rights relate to the acquisition,  transferability,
registration and listing of such shares of stock other securities  issuable upon
exercise  thereof),  or (C) in the event of an exchange or tender offer or other
transaction  contemplated by clause (3) of this Section, tender or exchange this
Warrant for such securities,  stock, cash and other property  receivable upon or
deemed to be held by holders of Common  Stock that have  tendered  or  exchanged
their shares of Common Stock  following such tender or exchange,  and the Holder
shall be  entitled  upon  such  exchange  or tender to  receive  such  amount of
securities,  cash and  property  as the  shares of Common  Stock for which  this
Warrant could have been exercised  immediately  prior to such tender or exchange
would have been  entitled as would have been issued.  In the case of clause (B),
the exercise  price  applicable for the newly issued warrant shall be based upon
the amount of  securities,  cash and  property  that each share of Common  Stock
would receive in such  transaction and the Exercise Price  immediately  prior to
the  effectiveness or closing date for such  transaction.  The terms of any such
merger, sale,  consolidation,  tender or exchange shall include such terms so as
continue  to give the  Holder  the right to  receive  the  securities,  cash and
property set forth in this Section upon any  conversion or redemption  following
such event. This provision shall similarly apply to successive such events.

            (v) For the purposes of this Section 8, the following  clauses shall
also be applicable:

                  (i) Record  Date.  In case the Company  shall take a record of
            the holders of its Common  Stock for the purpose of  entitling  them
            (A) to receive a dividend  or other  distribution  payable in Common
            Stock or in securities  convertible or  exchangeable  into shares of
            Common Stock,  or (B) to subscribe  for or purchase  Common Stock or

<PAGE>

            securities  convertible or exchangeable into shares of Common Stock,
            then such record date shall 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)  Treasury  Shares.  The number of shares of Common  Stock
            outstanding at any given time shall not include shares owned or held
            by or for the account of the  Company,  and the  disposition  of any
            such shares shall be considered an issue or sale of Common Stock.

            (vi) All  calculations  under  this  Section  8 shall be made to the
nearest cent or the nearest 1/100th of a share, as the case may be.

            (vii)  Whenever the Exercise  Price is adjusted  pursuant to Section
8(iii) above, the Holder,  after receipt of the  determination by the Appraiser,
shall  have the  right to  select  an  additional  appraiser  (which  shall be a
nationally  recognized  accounting  firm), in which case the adjustment shall be
equal to the average of the adjustments recommended by each of the Appraiser and
such  appraiser.  The Holder  shall  promptly  mail or cause to be mailed to the
Company,  a notice  setting forth the Exercise  Price after such  adjustment and
setting forth a brief  statement of the facts  requiring such  adjustment.  Such
adjustment  shall become effective  immediately  after the record date mentioned
above.

            (viii) If (i)the  Company  shall  declare a  dividend  (or any other
distribution)  on its Common  Stock;  (ii) the Company  shall  declare a special
nonrecurring  cash dividend on or a redemption  of its Common  Stock;  (iii) the
Company  shall  authorize the granting to all holders of the Common Stock rights
or warrants to  subscribe  for or  purchase  any shares of capital  stock of any
class or of any rights;  (iv) the  approval of any  stockholders  of the Company
shall be required in connection with any  reclassification  of the Common Stock,
any  consolidation  or  merger  to which  the  Company  is a party,  any sale or
transfer  of all or  substantially  all of the  assets  of the  Company,  or any
compulsory  share  exchange  whereby the Common  Stock is  converted  into other
securities,  cash or property;  or (v) the Company shall authorize the voluntary
dissolution,  liquidation or winding up of the affairs of the Company,  then the
Company shall cause to be mailed to each Holder at their last  addresses as they
shall appear upon the Warrant  Register,  at least twenty calendar days prior to
the applicable record or effective date hereinafter  specified, a notice stating
(x) the date on which a record is to be taken for the purpose of such  dividend,
distribution,  redemption, grant of rights or warrants, or if a record is not to
be taken,  the date as of which  the  holders  of  Common  Stock of record to be
entitled to such dividend, distributions,  redemption, rights or warrants are to
be  determined  or (y) the date on which such  reclassification,  consolidation,
merger,  sale,  transfer or share  exchange is expected to become  effective  or
close,  and the date as of which it is expected  that holders of Common Stock of
record  shall  be  entitled  to  exchange  their  shares  of  Common  Stock  for
securities,  cash or other  property  deliverable  upon  such  reclassification,
consolidation,  merger, sale, transfer, share exchange, dissolution, liquidation
or winding up;  provided,  however,  that the failure to mail such notice or any
defect  therein or in the mailing  thereof  shall not affect the validity of the
corporate action required to be specified in such notice.

9.   Payment of Exercise Price.  The Holder may pay the Exercise Price in one of
     the following manners:

(a)  Cash Exercise. The Holder shall deliver immediately available funds; or

(b)  Cashless  Exercise.  The Holder may  surrender  this Warrant to the Company
     together  with a notice of  cashless  exercise,  in which event the Company
     shall  issue to the  Holder  the number of  Warrant  Shares  determined  as
     follows:

                        X = Y (A-B)/A where:
                        X = the  number  of  Warrant  Shares to be issued to the
Holder.

                        Y = the number of Warrant  Shares with  respect to which
                        this Warrant is being exercised.

                        A = the average of the closing sale prices of the Common
                        Stock on the AMEX or a  Subsequent  Market  for the five
                        (5)  trading   days   immediately   prior  to  (but  not
                        including) the Date of Exercise as reported by Bloomberg
                        Information  Systems,  Inc.  (or  any  successor  to its
                        function of reporting stock prices).

                        B = the Exercise Price.

For purposes of Rule 144  promulgated  under the Securities Act, it is intended,
understood  and  acknowledged  that the  Warrant  Shares  issued  in a  cashless
exercise  transaction  shall be deemed to have been acquired by the Holder,  and
the  holding  period  for the  Warrant  Shares  shall  be  deemed  to have  been
commenced, on the issue date of this Warrant.

      10.   Certain Exercise Restrictions.

(a) A Holder may not  exercise  this Warrant to the extent such  exercise  would
result in the Holder,  together with any affiliate thereof,  beneficially owning
(as  determined  in  accordance  with Section  13(d) of the Exchange Act and the
rules  promulgated  thereunder)  in  excess of  9.999%  of the then  issued  and
outstanding  shares of Common Stock,  including  shares of Common Stock issuable
upon such  exercise and held by such Holder after  application  of this Section.
Since the Holder  will not be  obligated  to report to the Company the number of
shares of Common Stock it may hold at the time of an exercise hereunder,  unless
the  exercise at issue would result in the issuance of shares of Common Stock in
excess of 9.999% of the then  outstanding  shares of Common Stock without regard
to any other  shares  of Common  Stock  which may be  beneficially  owned by the
Holder  or an  affiliate  thereof,  the  Holder  shall  have the  authority  and
obligation to determine  whether the restriction  contained in this Section will
limit any  particular  exercise  hereunder  and to the  extent  that the  Holder
determines  that  the  limitation   contained  in  this  Section  applies,   the

<PAGE>

determination  of which  portion  of this  Warrant is  exercisable  shall be the
responsibility  and obligation of the Holder. If the Holder has delivered a Form
of Election to Purchase for a number of Warrant  Shares that would result in the
issuance in excess of the permitted amount  hereunder,  the Company shall notify
the Holder of this fact and shall honor the exercise for the maximum  portion of
this Warrant  permitted  to be exercised on such Date of Exercise in  accordance
with the  periods  described  herein and  disregard  the balance of such Form of
Election to Purchase,  as if never  delivered The provisions of this Section may
be waived by a Holder (but only as to itself and not to any other  Holder)  upon
not less than 61 days'  prior  notice to the  Company.  Other  Holders  shall be
unaffected by any such waiver.

            (b) If the Company  Stock is then listed for trading on the AMEX and
the Company has not obtained the Shareholder  Approval (as defined below),  then
the Company may not issue in excess of the Issuable  Maximum (as defined herein)
Warrant  Shares upon  exercise of this Warrant at a price per share that is less
than the closing sale price of the Common  Stock on the Trading Day  immediately
preceding the Original Issue Date. The Issuable  Maximum equals 3,400,297 (which
number shall be subject to adjustment  pursuant to the anti-dilution  provisions
set  forth in  Sections  8(i)-(iii))  multiplied  by the  quotient  obtained  by
dividing (x) the number of Shares issued and sold to the original  Holder on the
Closing  Date by (y) the number of Shares  issued and sold by the Company on the
Closing Date.  The Parties  agree that the Issuable  Maximum shall be lowered by
the number of shares of Common  Stock,  if any,  issued at a price less than the
closing  price of the Common Stock on December 8, 1999  pursuant to the Warrants
to  Advantage  Fund II Ltd and  Koch  Investment  Group  Ltd.  If on any Date of
Exercise  (such date, the "Trigger  Date"):  (A) the Company Stock is listed for
trading on the AMEX,  (B) the  aggregate  number of shares of Common  Stock that
would then be issuable upon exercise in full of this Warrant,  together with any
shares of Common Stock  previously  issued upon exercise of this Warrant,  would
equal or  exceed  the  Issuable  Maximum,  and (C) the  Company  shall  not have
previously obtained the vote of shareholders,  if any, as may be required by the
applicable  rules and  regulations of the American Stock Exchange to approve the
issuance of shares of Common Stock in excess of the Issuable Maximum pursuant to
the terms hereof (the "Shareholder  Approval"),  then the Company shall issue to
the Holder a number of shares of Common Stock equal to the Issuable Maximum and,
with respect to the shares whose  issuance would result in an issuance of shares
of  Common  Stock in  excess  of the  Issuable  Maximum,  (the  "Excess  Warrant
Shares"),  the Company shall, within three (3) Trading Days of the Trigger Date,
provide the Holder with  written  notice of its  intention to either (1) use its
best efforts to obtain the Shareholder  Approval  applicable to such issuance as
soon as possible, but in any event no later than 60 days (or 90 days in case the
Commission  provides the Company with comments to its proxy  material) after the
Trigger Date (such 60th day or 90th day, if  applicable,  the "Target  Date") or
(2) pay to the Holder,  within three (3) Trading Days from the Trigger  Date, an
amount in cash equal to the product of (x) the Excess Warrant Shares  multiplied
by (y) the closing sales price of the Common Stock on (a) the Target Date or (b)
the Trigger Date,  whichever is greater (the "Cash  Payment").  A failure by the
Company to timely  provide  the Holder  with a written  notice  pursuant  to the
immediately  preceding  sentence,  shall  entail an  automatic  election  by the
Company  to pay the Cash  Payment to the  Holder  pursuant  to clause (2) of the
immediately preceding sentence. In the event the Company has elected to seek the
Shareholder  Approval  pursuant  to the terms  hereof and the  Company  does not
obtain the  Shareholder  Approval on or prior to the Target Date,  then,  on the
Target  Date,  the  Company  shall pay the Cash  Payment to the  Holder.  If the
Company  fails to pay the Cash Payment in full  pursuant to this Section  within
seven (7) days after the date  payable,  the Company  will pay  interest on such

<PAGE>

amount  at a rate of 18%  per  annum,  or such  lesser  maximum  amount  that is
permitted to be paid by applicable  law, to the Holder,  accruing daily from the
date payable until such amount, plus all such interest thereon, is paid in full.
The Company  and the Holder  understand  and agree that  shares of Common  Stock
issued upon exercise of this Warrant and then held by the Holder or an affiliate
thereof may not be used to cast votes or be deemed  outstanding  for purposes of
any vote to obtain  the  Shareholder  Approval.  In the event  the  Company  has
elected to seek the  Shareholder  Approval  pursuant  to the terms  hereof,  the
Company  shall not be required  to make any  payments  pursuant to Section  4(b)
hereof prior to the date the Company has obtained the Shareholder Approval.

      11.   [intentionally left bank]

      12. Fractional Shares. The Company shall not be required to issue or cause
to be issued  fractional  Warrant  Shares on the exercise of this  Warrant.  The
number of full Warrant  Shares which shall be issuable upon the exercise of this
Warrant shall be computed on the basis of the aggregate number of Warrant Shares
purchasable  on  exercise of this  Warrant so  presented.  If any  fraction of a
Warrant Share would,  except for the  provisions of this Section 12, be issuable
on the exercise of this  Warrant,  the Company shall pay an amount in cash equal
to the Exercise Price multiplied by such fraction.

      13.  Notices.  Any and all notices or other  communications  or deliveries
hereunder  shall be in writing and shall be deemed  given and  effective  on the
earliest of (i) the date of  transmission,  if such notice or  communication  is
delivered  via  facsimile at the facsimile  telephone  number  specified in this
Section  prior to 5:00 p.m.  (New York City  time) on a Business  Day,  (ii) the
Business Day after the date of transmission,  if such notice or communication is
delivered  via  facsimile at the facsimile  telephone  number  specified in this
Section  later than 5:00 p.m.  (New York City time) on any date and earlier than
11:59 p.m.  (New York City time) on such date,  (iii) the Business Day following
the date of mailing, if sent by nationally  recognized overnight courier service
with next day delivery  specified  thereon,  or (iv) upon actual  receipt by the
party to whom  such  notice is  required  to be given.  The  addresses  for such
communications  shall be: (i) if to the Company, to 8229 Boone Boulevard,  Suite
802, Vienna,  Virginia 22182;  facsimile number (703) 506-9471,  attention Geert
Kersten,  or (ii) if to the Holder,  to the Holder at the  address or  facsimile
number  appearing  on the Warrant  Register or such other  address or  facsimile
number as the Holder may provide to the Company in accordance  with this Section
13.

      14.   Warrant Agent.

Upon  thirty  (30) days'  notice to the  Holder,  the  Company may appoint a new

            (c) The  corporate  laws of the State of Colorado  shall  govern all
