                             STOCK PURCHASE WARRANT


                   To Purchase 395,726 Shares of Common Stock of

                               CEL-SCI CORPORATION

            THIS CERTIFIES that, for value received, Rubicon Group Ltd. (the
"Holder"), is entitled, upon the terms and subject to the limitations on
exercise and the conditions hereinafter set forth, at any time on or after
September 16, 2003 (the "Initial Exercise Date") and on or prior to the close of
business on September 16, 2008 (the "Termination Date") but not thereafter, to
subscribe for and purchase from CEL-SCI Corporation, a corporation incorporated
in the State of Colorado (the "Company"), up to 395,726 shares (the "Warrant
Shares") of Common Stock, $0.01 par value per share, of the Company (the "Common
Stock"). The purchase price of one share of Common Stock (the "Exercise Price")
under this Warrant shall be $0.83, subject to adjustment herein. The Exercise
Price and the number of Warrant Shares for which the Warrant is exercisable
shall be subject to adjustment as provided herein. In the event of any conflict
between the terms of this Warrant and the Common Stock Purchase Agreement dated
as of September 16, 2003 pursuant to which this Warrant has been issued (the
"Purchase Agreement"), the Purchase Agreement shall control. Capitalized terms
used and not otherwise defined herein shall have the meanings set forth for such
terms in the Purchase Agreement.

   1.    Title  to  Warrant.  Prior  to the  Termination  Date  and  subject  to
compliance  with  applicable  laws,  this Warrant and all rights  hereunder  are
transferable, in whole or in part, at the office or agency of the Company by the
Holder in person or by duly authorized attorney,  upon surrender of this Warrant
together with the Assignment Form annexed hereto properly endorsed.

   2.    Authorization of Shares.  The Company covenants that all Warrant Shares
which may be issued upon the exercise of the purchase rights represented by this
Warrant will, upon exercise of the purchase rights  represented by this Warrant,
be duly authorized,  validly issued,  fully paid and nonassessable and free from
all taxes,  liens and charges in respect of the issue thereof  (other than taxes
in respect of any transfer occurring contemporaneously with such issue).




   3.    Exercise of Warrant.

(a)  Except as provided in Section 4 herein,  exercise  of the  purchase  rights
     represented  by this  Warrant  may be made at any time or times on or after
     the  Initial  Exercise  Date and on or before the  Termination  Date by the
     surrender  of this Warrant and the Notice of Exercise  Form annexed  hereto
     duly executed, at the office of the Company (or such other office or agency
     of the Company as it may  designate by notice in writing to the  registered
     Holder at the address of such Holder appearing on the books of the Company)
     and upon payment of the Exercise Price of the shares  thereby  purchased by
     wire transfer or cashier's  check drawn on a United States bank or by means
     of a  cashless  exercise,  the  Holder  shall  be  entitled  to  receive  a
     certificate for the number of Warrant Shares so purchased. Certificates for
     shares  purchased  hereunder shall be delivered to the Holder at an address
     in the United  States  specified in writing by the Holder  within three (3)
     Trading Days after the date on which this Warrant shall have been exercised
     as aforesaid;  provided, however, if a registration registering the sale of
     the Warrant Shares is then effective or the shares may be issue pursuant to
     Rule  144  without  a  legend  (and the  customary  documentation  has been
     provided for such sale), the Warrant Shares shall be delivered  directly to
     the  Holder's  or its  designee's  DTC account  via the DWAC  system.  This
     Warrant  shall be deemed to have been  exercised  and such  certificate  or
     certificates  shall be deemed to have been issued,  and Holder or any other
     person so  designated  to be named therein shall be deemed to have become a
     holder  of  record  of such  shares  for all  purposes,  as of the date the
     Warrant has been  exercised by payment to the Company of the Exercise Price
     and all  taxes  required  to be paid by the  Holder,  if any,  pursuant  to
     Section 5 prior to the  issuance  of such  shares,  have been paid.  If the
     Company  fails to  deliver  to the  Holder a  certificate  or  certificates
     representing  the Warrant Shares pursuant to this Section 3(a) by the third
     Trading Day after the date of exercise, then the Holder will have the right
     to rescind such exercise.  In addition to any other rights available to the
     Holder,  if the  Company  fails to deliver to the Holder a  certificate  or
     certificates representing the Warrant Shares pursuant to an exercise by the
     third  Trading  Day after the date of  exercise,  and if after  such  third
     Trading Day the Holder is  required  by its broker to purchase  (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 (1) pay 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 number of Warrant Shares that the Company was required
     to deliver to the Holder in connection with the exercise at issue times (B)
     the price at which the sell order giving rise to such  purchase  obligation
     was  executed,  and (2) at the option of the Holder,  either  reinstate the
     portion of the Warrant and  equivalent  number of Warrant  Shares for which
     such exercise was not honored or 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  hereunder.  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 an aggregate sale price giving rise to such purchase  obligation
     of $10,000,  under  clause (1) 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, together with applicable confirmations and
     other evidence  reasonably  requested by the Company.  Nothing herein shall
     limit a  Holder's  right to  pursue  any  other  remedies  available  to it
     hereunder, at law or in equity including,  without limitation,  a decree of
     specific performance and/or injunctive relief with respect to the Company's
     failure to timely deliver certificates  representing shares of Common Stock
     upon exercise of the Warrant as required pursuant to the terms hereof.

(b)  If this Warrant shall have been exercised in part,  the Company  shall,  at
     the  time of  delivery  of the  certificate  or  certificates  representing
     Warrant  Shares,  deliver to Holder a new Warrant  evidencing the rights of
     Holder to  purchase  the  unpurchased  Warrant  Shares  called  for by this
     Warrant,  which new Warrant shall in all other  respects be identical  with
     this Warrant.

(c)  If no  registration  statement  is effective  permitting  the resale of the
     Warrant  Shares at any time  commencing  one year after the  issuance  date
     hereof,  this  Warrant  shall also be  exercisable  by means of a "cashless
     exercise"  in which the Holder  shall be entitled to receive a  certificate
     for the number of Warrant Shares equal to the quotient obtained by dividing
     [(A-B) (X)] by (A), where:

                  (A) = the average of the high and low trading prices per share
                  of Common Stock on the Trading Day preceding the date of such
                  election on the Nasdaq Stock Market, or if the Common Stock is
                  not traded on the Nasdaq Stock Market, then the Principal
                  Market in terms of volume;

                  (B) = the Exercise Price of this Warrant; and

                  (X) = the number of Warrant Shares issuable upon exercise of
                  this Warrant in accordance with the terms of this Warrant and
                  the Notice of Exercise.

(d)  Notwithstanding  anything  herein to the  contrary,  in no event  shall the
     Holder be  permitted  to exercise  this  Warrant for Warrant  Shares to the
     extent  that (i) the number of shares of Common  Stock owned by such Holder
     (other than Warrant  Shares  issuable  upon  exercise of this Warrant) plus
     (ii) the number of Warrant  Shares  issuable upon exercise of this Warrant,
     would be equal to or exceed  4.9% of the  number of shares of Common  Stock
     then issued and  outstanding,  including  shares  issuable upon exercise of
     this Warrant held by such Holder after application of this Section 3(d). As
     used herein,  beneficial  ownership  shall be determined in accordance with
     Section  13(d) of the  Exchange  Act.  To the  extent  that the  limitation
     contained in this Section 3(d) applies,  the  determination of whether this
     Warrant  is  exercisable  (in  relation  to other  securities  owned by the
     Holder) and of which a portion of this Warrant is  exercisable  shall be in
     the sole  discretion  of such  Holder,  and the  submission  of a Notice of




     Exercise shall be deemed to be such Holder's  determination of whether this
     Warrant is  exercisable  (in  relation  to other  securities  owned by such
     Holder) and of which portion of this Warrant is  exercisable,  in each case
     subject to such aggregate percentage limitation, and the Company shall have
     no  obligation  to verify or confirm the  accuracy  of such  determination.
     Nothing  contained herein shall be deemed to restrict the right of a Holder
     to exercise this Warrant into Warrant  Shares at such time as such exercise
     will not violate the  provisions  of this Section 3(d).  The  provisions of
     this Section 3(d) may be waived by the Holder upon,  at the election of the
     Holder,  with not less than 61 days' prior notice to the  Company,  and the
     provisions of this Section 3(d) shall continue to apply until such 61st day
     (or such later  date as may be  specified  in such  notice of  waiver).  No
     exercise of this Warrant in violation of this Section 3(d) but otherwise in
     accordance with this Warrant shall affect the status of the Warrant Shares
      as validly issued, fully-paid and nonassessable.

   4.    No  Fractional   Shares  or  Scrip.  No  fractional   shares  or  scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant.  As to any fraction of a share which Holder would otherwise be entitled
to purchase  upon such  exercise,  the Company  shall pay a cash  adjustment  in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

   5.   Charges, Taxes and Expenses. Issuance of certificates for Warrant Shares
shall be made  without  charge to the  Holder for any issue or  transfer  tax or
other incidental expense in respect of the issuance of such certificate,  all of
which taxes and  expenses  shall be paid by the Company,  and such  certificates
shall be  issued  in the name of the  Holder  or in such name or names as may be
directed by the Holder;  provided,  however,  that in the event certificates for
Warrant  Shares are to be issued in a name  other  than the name of the  Holder,
this  Warrant  when  surrendered  for  exercise  shall  be  accompanied  by  the
Assignment Form attached hereto duly executed by the Holder; and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

   6.   Closing of Books. Unless required by law, the Company will not close its
stockholder books or records in any manner which prevents the timely exercise of
this Warrant.

   7.    Transfer, Division and Combination.

(a)  Subject to compliance with any applicable securities laws, transfer of this
     Warrant and all rights hereunder,  in whole or in part, shall be registered
     on the  books  of the  Company  to be  maintained  for such  purpose,  upon
     surrender of this Warrant at the principal office of the Company,  together
     with a  written  assignment  of  this  Warrant  substantially  in the  form
     attached  hereto duly  executed by the Holder or its agent or attorney  and
     funds  sufficient to pay any transfer taxes payable upon the making of such
     transfer. In the event that the Holder wishes to transfer a portion of this
     Warrant,  the Holder shall transfer at least 100,000 shares underlying this
     Warrant to any such transferee.  Upon such surrender and, if required, such
     payment, the Company shall execute and deliver a new Warrant or Warrants in
     the  name  of  the  assignee  or  assignees  and  in  the  denomination  or



     denominations  specified in such instrument of assignment,  and shall issue
     to the assignor a new Warrant evidencing the portion of this Warrant not so
     assigned,  and this Warrant  shall  promptly be  cancelled.  A Warrant,  if
     properly  assigned,  may be  exercised  by a new holder for the purchase of
     Warrant Shares without having a new Warrant issued.

(b)  This  Warrant  may  be  divided  or  combined  with  other   Warrants  upon
     presentation hereof at the aforesaid office of the Company, together with a
     written notice specifying the names and denominations in which new Warrants
     are to be issued, signed by the Holder or its agent or attorney. Subject to
     compliance  with Section 7(a), as to any transfer  which may be involved in
     such division or  combination,  the Company shall execute and deliver a new
     Warrant or Warrants  in exchange  for the Warrant or Warrants to be divided
     or combined in accordance with such notice.

(c)  The Company shall prepare, issue and deliver at its own expense (other than
     transfer taxes) the new Warrant or Warrants under this Section 7.

(d)  The Company  agrees to maintain,  at its  aforesaid  office,  books for the
     registration and the registration of transfer of the Warrants.

  8.    No Rights as Shareholder  until Exercise.  This Warrant does not entitle
the Holder to any voting rights or other rights as a shareholder  of the Company
prior to the exercise hereof. Upon the surrender of this Warrant and the payment
of the aggregate Exercise Price or by means of a cashless exercise,  the Warrant
Shares so  purchased  shall be and be deemed to be issued to such  Holder as the
record owner of such shares as of the close of business on the later of the date
of such surrender or payment.

   9.   Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants
that upon receipt by the Company of evidence  reasonably  satisfactory  to it of
the  loss,  theft,  destruction  or  mutilation  of this  Warrant  or any  stock
certificate  relating  to the  Warrant  Shares,  and in case of  loss,  theft or
destruction, of indemnity or security reasonably satisfactory to it (which shall
not include the posting of any bond),  and upon  surrender and  cancellation  of
such  Warrant or stock  certificate,  if  mutilated,  the Company  will make and
deliver a new  Warrant or stock  certificate  of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

  10.    Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the  expiration of any right  required or granted herein
shall be a Saturday, Sunday or a legal holiday, then such action may be taken or
such right may be exercised on the next succeeding day not a Saturday, Sunday or
legal holiday.

  11.     Adjustments of Exercise Price and Number of Warrant Shares.  (a) Stock
Splits, etc. The number and kind of securities  purchasable upon the exercise of
this Warrant and the Exercise Price shall be subject to adjustment  from time to
time upon the happening of any of the  following.  In case the Company shall (i)
pay a dividend  in shares of Common  Stock or make a  distribution  in shares of
Common Stock to holders of its  outstanding  Common  Stock,  (ii)  subdivide its
outstanding  shares  of Common  Stock  into a greater  number of  shares,  (iii)
combine its  outstanding  shares of Common Stock into a smaller number of shares
of  Common  Stock,  or  (iv)  issue  any  shares  of  its  capital  stock  in  a
reclassification  of the  Common  Stock,  then  the  number  of  Warrant  Shares
purchasable  upon  exercise of this Warrant  immediately  prior thereto shall be
adjusted so that the Holder  shall be entitled to receive the kind and number of




Warrant  Shares or other  securities of the Company which it would have owned or
have been  entitled  to  receive  had such  Warrant  been  exercised  in advance
thereof.  Upon each such  adjustment of the kind and number of Warrant Shares or
other  securities of the Company  which are  purchasable  hereunder,  the Holder
shall  thereafter be entitled to purchase the number of Warrant  Shares or other
securities resulting from such adjustment at an Exercise Price per Warrant Share
or  other  security  obtained  by  multiplying  the  Exercise  Price  in  effect
immediately prior to such adjustment by the number of Warrant Shares purchasable
pursuant hereto  immediately prior to such adjustment and dividing by the number
of  Warrant  Shares  or other  securities  of the  Company  resulting  from such
adjustment. An adjustment made pursuant to this paragraph shall become effective
immediately  after the effective  date of such event  retroactive  to the record
date, if any, for such event.

  12.    Reorganization,  Reclassification, Merger, Consolidation or Disposition
of Assets.  In case the Company shall  reorganize  its capital,  reclassify  its
capital stock,  consolidate or merge with or into another corporation (where the
Company  is not the  surviving  corporation  or where  there  is a change  in or
distribution with respect to the Common Stock of the Company), or sell, transfer
or  otherwise  dispose  of all or  substantially  all its  property,  assets  or
business   to  another   corporation   and,   pursuant  to  the  terms  of  such
reorganization,   reclassification,  merger,  consolidation  or  disposition  of
assets, shares of common stock of the successor or acquiring corporation, or any
cash,  shares of stock or other securities or property of any nature  whatsoever
(including  warrants or other subscription or purchase rights) in addition to or
in lieu of  common  stock of the  successor  or  acquiring  corporation  ("Other
Property"),  are to be received by or distributed to the holders of Common Stock
of the Company, then the Holder shall have the right thereafter to receive, upon
exercise of this Warrant,  the number of shares of Common Stock of the successor
or acquiring corporation or of the Company, if it is the surviving  corporation,
and  Other  Property  receivable  upon or as a  result  of such  reorganization,
reclassification,  merger, consolidation or disposition of assets by a Holder of
the  number of shares of Common  Stock for which  this  Warrant  is  exercisable
immediately   prior  to  such  event.  In  case  of  any  such   reorganization,
reclassification,  merger, consolidation or disposition of assets, the successor
or acquiring  corporation (if other than the Company) shall expressly assume the
due and  punctual  observance  and  performance  of each and every  covenant and
condition of this  Warrant to be  performed  and observed by the Company and all
the obligations and liabilities hereunder,  subject to such modifications as may
be deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for  adjustments of Warrant Shares
for which this Warrant is  exercisable  which shall be as nearly  equivalent  as
practicable to the adjustments  provided for in this Section 12. For purposes of
this Section 12, "common stock of the successor or acquiring  corporation" shall
include  stock of such  corporation  of any class which is not  preferred  as to
dividends or assets over any other class of stock of such  corporation and which
is  not  subject  to  redemption   and  shall  also  include  any  evidences  of
indebtedness,  shares of stock or other securities which are convertible into or
exchangeable  for any such stock,  either  immediately  or upon the arrival of a
specified  date or the happening of a specified  event and any warrants or other
rights to subscribe for or purchase any such stock. The foregoing  provisions of
this  Section  12  shall   similarly   apply  to   successive   reorganizations,
reclassifications, mergers, consolidations or disposition of assets.




  13.    Voluntary Adjustment by the Company. The Company may at any time during
the term of this Warrant  reduce the then current  Exercise  Price to any amount
and for any period of time deemed  appropriate  by the Board of Directors of the
Company.

  14.    Notice of  Adjustment.  Whenever the number of Warrant Shares or number
or kind of securities or other  property  purchasable  upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
promptly mail by registered or certified mail, return receipt requested,  to the
Holder  notice of such  adjustment  or  adjustments  setting forth the number of
Warrant Shares (and other securities or property)  purchasable upon the exercise
of this  Warrant  and the  Exercise  Price of such  Warrant  Shares  (and  other
securities or property) after such  adjustment,  setting forth a brief statement
of the facts  requiring  such  adjustment  and setting forth the  computation by
which such adjustment was made.  Such notice,  in the absence of manifest error,
shall be conclusive evidence of the correctness of such adjustment.

  15.    Notice of Corporate Action. If at any time:

                  (a) the Company shall take a record of the holders of its
      Common Stock for the purpose of entitling them to receive a dividend or
      other distribution, or any right to subscribe for or purchase any
      evidences of its indebtedness, any shares of stock of any class or any
      other securities or property, or to receive any other right, or

                  (b) there shall be any capital reorganization of the Company,
      any reclassification or recapitalization of the capital stock of the
      Company or any consolidation or merger of the Company with, or any sale,
      transfer or other disposition of all or substantially all the property,
      assets or business of the Company to, another corporation or,

                  (c) there shall be a voluntary or involuntary dissolution,
      liquidation or winding up of the Company;

then, in any one or more of such cases,  the Company shall give to Holder (i) at
least 20 days' prior written  notice of the date on which a record date shall be
selected for such dividend,  distribution or right or for determining  rights to
vote  in  respect  of  any  such   reorganization,   reclassification,   merger,
consolidation, sale, transfer, disposition,  liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
days'  prior  written  notice of the date when the same shall take  place.  Such
notice in accordance  with the foregoing  clause also shall specify (i) the date
on which  any such  record  is to be taken  for the  purpose  of such  dividend,
distribution  or right,  the date on which the holders of Common  Stock shall be
entitled  to any such  dividend,  distribution  or  right,  and the  amount  and
character  thereof,  and  (ii)  the  date  on  which  any  such  reorganization,
reclassification,    merger,   consolidation,   sale,   transfer,   disposition,
dissolution,  liquidation  or winding  up is to take place and the time,  if any
such  time is to be fixed,  as of which the  holders  of Common  Stock  shall be
entitled to exchange  their  Warrant  Shares for  securities  or other  property




deliverable upon such disposition,  dissolution, liquidation or winding up. Each
such written  notice shall be  sufficiently  given if addressed to Holder at the
last address of Holder  appearing  on the books of the Company and  delivered in
accordance with Section 17(d).

  16.     Authorized  Shares.  The Company  covenants that during the period the
Warrant is outstanding,  it will reserve from its authorized and unissued Common
Stock a  sufficient  number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant.  The Company
further  covenants  that its  issuance of this  Warrant  shall  constitute  full
authority  to its  officers  who are charged  with the duty of  executing  stock
certificates  to execute and issue the  necessary  certificates  for the Warrant
Shares upon the exercise of the purchase rights under this Warrant.  The Company
will take all such  reasonable  action as may be  necessary  to assure that such
Warrant  Shares  may be issued  as  provided  herein  without  violation  of any
applicable law or regulation,  or of any  requirements  of the Principal  Market
upon which the Common Stock may be listed.

     The  Company  shall  not  by any  action,  including,  without  limitation,
amending  its  certificate  of  incorporation  or  through  any  reorganization,
transfer  of  assets,  consolidation,  merger,  dissolution,  issue  or  sale of
securities or any other voluntary action,  avoid or seek to avoid the observance
or  performance  of any of the terms of this  Warrant,  but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or  appropriate to protect the rights of Holder
against  impairment.  Without  limiting the  generality  of the  foregoing,  the
Company  will (a) not  increase  the par value of any Warrant  Shares  above the
amount payable therefor upon such exercise immediately prior to such increase in
par value,  (b) take all such action as may be necessary or appropriate in order
that the Company may  validly  and  legally  issue fully paid and  nonassessable
Warrant  Shares upon the  exercise  of this  Warrant,  and (c) use  commercially
reasonable  efforts to obtain all such  authorizations,  exemptions  or consents
from any public regulatory body having jurisdiction  thereof as may be necessary
to enable the Company to perform its obligations under this Warrant.

     Before  taking any action which would result in an adjustment in the number
of Warrant  Shares for which this  Warrant  is  exercisable  or in the  Exercise
Price, the Company shall obtain all such  authorizations or exemptions  thereof,
or consents  thereto,  as may be necessary  from any public  regulatory  body or
bodies having jurisdiction thereof.

   17.     Miscellaneous.

(a)  Jurisdiction.  This Warrant shall  constitute a contract  under the laws of
     New York, without regard to its conflict of law, principles or rules.

(b)  Restrictions. The Holder acknowledges that the Warrant Shares acquired upon
     the exercise of this Warrant,  if not  registered,  will have  restrictions
     upon resale imposed by state and federal securities laws.

(c)  Nonwaiver  and  Expenses.  No course of  dealing or any delay or failure to
     exercise  any right  hereunder  on the part of Holder  shall  operate  as a
     waiver of such right or  otherwise  prejudice  Holder's  rights,  powers or
     remedies, notwithstanding all rights hereunder terminate on the Termination




     Date.  If the  Company  willfully  and  knowingly  fails to comply with any
     provision of this  Warrant,  which  results in any material  damages to the
     Holder, the Company shall pay to Holder such amounts as shall be sufficient
     to cover any costs and expenses  including,  but not limited to, reasonable
     attorneys'  fees,  including  those of appellate  proceedings,  incurred by
     Holder in  collecting  any  amounts  due  pursuant  hereto or in  otherwise
     enforcing any of its rights, powers or remedies hereunder.

(d)   Notices. Any notice, request or other document required or permitted to be
      given or delivered to the Holder by the Company shall be delivered in
      accordance with the notice provisions of the Purchase Agreement.

(e)  Limitation of Liability. No provision hereof, in the absence of affirmative
     action by Holder to purchase Warrant Shares,  and no enumeration  herein of
     the rights or  privileges  of Holder,  shall give rise to any  liability of
     Holder for the purchase  price of any Common Stock or as a  stockholder  of
     the  Company,  whether  such  liability  is  asserted  by the Company or by
     creditors of the Company.

(f)  Remedies.  Holder,  in  addition to being  entitled to exercise  all rights
     granted by law, including recovery of damages, will be entitled to specific
     performance  of its rights  under this  Warrant.  The  Company  agrees that
     monetary  damages would not be adequate  compensation for any loss incurred
     by reason of a breach by it of the  provisions  of this  Warrant and hereby
     agrees to waive the defense in any action for specific  performance  that a
     remedy at law would be adequate.

(g)  Successors and Assigns. Subject to applicable securities laws, this Warrant
     and the rights and obligations  evidenced hereby shall inure to the benefit
     of and be binding upon the successors of the Company and the successors and
     permitted assigns of Holder. The provisions of this Warrant are intended to
     be for the  benefit of all  Holders  from time to time of this  Warrant and
     shall be enforceable by any such Holder or holder of Warrant Shares.

(h)   Amendment. This Warrant may be modified or amended or the provisions
      hereof waived with the written consent of the Company and the Holder.

(i)   Severability. Wherever possible, each provision of this Warrant shall be
      interpreted in such manner as to be effective and valid under applicable
      law, but if any provision of this Warrant shall be prohibited by or
      invalid under applicable law, such provision shall be ineffective to the
      extent of such prohibition or invalidity, without invalidating the
      remainder of such provisions or the remaining provisions of this Warrant.

(j)   Headings. The headings used in this Warrant are for the convenience of
      reference only and shall not, for any purpose, be deemed a part of this
      Warrant.







      IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by
its officer thereunto duly authorized.

                    NOTICE OF EXERCISE OF COMMON STOCK WARRANT
                    PURSUANT TO CASHLESS EXERCISE PROVISIONS


To: Cel-SCI Corporation

Aggregate Price of Warrant Before Exercise:  $_______
Aggregate Price Being Exercised:  $______
Exercise Price:  $______ per share
Number of Shares of Common Stock to be Issued Under this Notice:  _______
Remaining Aggregate Price (if any) After Issuance:  $_______

Gentlemen:

     The  undersigned,  registered  Holder of the  Warrant  delivered  herewith,
hereby irrevocably exercises such Warrant for, and purchases thereunder,  shares
of the Common Stock of Cel-SCI Corporation, a Colorado corporation,  as provided
below.  Capitalized terms used herein,  unless otherwise  defined herein,  shall
have the meanings  given in the Warrant.  The portion of the Exercise  Price (as
defined in the  Warrant)  to be  applied  toward the  purchase  of Common  Stock
pursuant to this Notice of Exercise  is  $_______,  thereby  leaving a remaining
Exercise  Price (if any) equal to $________.  Such exercise shall be pursuant to
the cashless exercise provisions of Section 3 of the Warrant;  therefore, Holder
makes no payment with this Notice of Exercise. The number of shares to be issued
pursuant to this  exercise  shall be  determined  by reference to the formula in
Section 3 of the Warrant  which,  by reference to Section 3, requires the use of
the high and low trading price of the Company's  Common Stock on the Trading Day
preceding  the date of such  election.  The high  and low  trading  price of the
Company's  Common  Stock  has  been  determined  by  Holder  to be  $______  and
$_________,  respectively, which figure is acceptable to Holder for calculations
of the number of shares of Common  Stock  issuable  pursuant  to this  Notice of
Exercise.  Holder  requests that the  certificates  for the purchased  shares of
Common Stock be issued in the name of  _______________________  and delivered to
________________________________________.  To the extent the foregoing  exercise
is for less than the full Aggregate Price of the Warrant, a replacement  Warrant
representing  the remainder of the Aggregate  Price (and otherwise of like form,
tenor and effect) shall be delivered to Holder along with the share  certificate
evidencing the Common Stock issued in response to this Notice of Exercise.
