                          COMMON STOCK PURCHASE WARRANT


                To Purchase 157,895 Shares of Common Stock of

                               Cytogen Corporation

     THIS COMMON STOCK PURCHASE  WARRANT  CERTIFIES  that,  for value  received,
_____________  (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  June 6,  2003 (the  "Initial  Exercise  Date") and on or prior to the
close of business on the fifth  anniversary  of the Initial  Exercise  Date (the
"Termination  Date") but not  thereafter,  to subscribe  for and  purchase  from
Cytogen  Corporation,  a corporation  incorporated in the State of Delaware (the
"Company"),  up to 157,895  shares (the "Warrant  Shares") of Common Stock,  par
value $0.01 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
$6.91,  subject to adjustment  hereunder.  The Exercise  Price and the number of
Warrant  Shares  for  which the  Warrant  is  exercisable  shall be  subject  to
adjustment as provided herein.  Capitalized terms used and not otherwise defined
herein shall have the meanings  set forth in that  certain  Securities  Purchase
Agreement (the "Purchase  Agreement"),  dated June 6, 2003,  between the Company
and the purchasers signatory thereto.


                                       1



     1.  Title  to  Warrant.  Prior  to the  Termination  Date  and  subject  to
compliance with applicable laws and Section 7 of this Warrant,  this Warrant and
all rights hereunder are  transferable,  in whole but not 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.  The transferee shall sign an investment  letter in form and
substance reasonably satisfactory to the Company.

     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  pursuant to Section  3(d),  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  within  seven (7) Trading  Days after the date on
     which this Warrant  shall have been  exercised as  aforesaid.  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 seventh  Trading Day
     after the date of exercise,  then the Holder will have the right to rescind
     such  exercise.  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

                                       2


     this Warrant,  which new Warrant  shall in all other  respects be identical
     with this Warrant.

          (c) 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  beneficially owned by
     such Holder, together with any affiliate thereof (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
     4.9999%  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(c).  As used herein,
     beneficial  ownership  shall be determined in accordance with Section 13(d)
     of the Exchange  Act and the rules  promulgated  thereunder.  To the extent
     that  the   limitation   contained  in  this  Section  3(c)  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(c).
     The  provisions  of this Section 3(c) may be waived by the Holder upon,  at
     the  election  of the Holder,  not less than 61 days'  prior  notice to the
     Company,  and the  provisions of this Section 3(c) shall  continue to apply
     until such 61st day (or such later date, as  determined  by the Holder,  as
     may be specified in such notice of waiver).  No exercise of this Warrant in
     violation  of this  Section  3(c) but  otherwise  in  accordance  with this
     Warrant  shall affect the status of the Warrant  Shares as validly  issued,
     fully-paid and nonassessable.

          (d) If at any time  after one year from the date of  issuance  of this
     Warrant there is no effective Registration Statement registering the resale
     of the Warrant Shares by the Holder,  this Warrant may also be exercised at
     such time 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  VWAP  on the  Trading  Day  preceding  the  date  of  such
               election;

          (B)  = the Exercise Price of the Warrants, as adjusted; and

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

     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

                                       3


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.  The Company will not close its  stockholder  books or
records in any  manner  which  prevents  the timely  exercise  of this  Warrant,
pursuant to the terms hereof.

     7. Transfer, Division and Combination.

          (a) Subject to compliance with any applicable  securities laws and the
     conditions set forth in Sections 1 and 7(d) hereof and to the provisions of
     Section  4.1 of  the  Purchase  Agreement,  this  Warrant  and  all  rights
     hereunder are  transferable,  in whole but not in part,  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.  Upon such surrender and, if required,  such payment, the Company
     shall  execute and deliver a new Warrant in the name of the assignee and in
     the  denomination  specified in such  instrument of  assignment,  and shall
     issue to the  assignor a new Warrant  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) The Company  shall  prepare,  issue and deliver at its own expense
     (other than transfer  taxes) the new Warrant or Warrants under this Section
     7.

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

          (d) If, at the time of the  surrender  of this  Warrant in  connection
     with any transfer of this  Warrant,  the transfer of this Warrant shall not
     be registered  pursuant to an effective  registration  statement  under the
     Securities Act and under  applicable state securities or blue sky laws, the
     Company may require,  as a condition of allowing such transfer (i) that the
     Holder or transferee of this  Warrant,  as the case may be,  furnish to the
     Company a written  opinion  of  counsel  (which  opinion  shall be in form,
     substance  and scope  customary  for  opinions  of  counsel  in  comparable
     transactions)  to  the  effect  that  such  transfer  may be  made  without
     registration under the Securities Act and under applicable state securities
     or blue sky laws, (ii) that the holder or transferee execute and deliver to

                                       4


     the Company an investment  letter in form and  substance  acceptable to the
     Company  and (iii)  that the  transferee  be an  "accredited  investor"  as
     defined in Rule 501(a) promulgated under the Securities Act.

     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, in
the case of the  Warrant,  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;  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.


                                       5


     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,  at
the option of the Holder, 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
give  notice  thereof to the  Holder,  which  notice  shall  state 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.


                                       6


     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 Trading Market upon
which the Common Stock may be listed.

     Except  and to the  extent as waived or  consented  to by the  Holder,  the
Company shall not by any action,  including,  without  limitation,  amending its
certificate of incorporation or through any reorganization,  transfer of assets,

7


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 as set forth in this
Warrant 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
     any  affirmative  action by Holder to  exercise  this  Warrant or  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

                                       8


     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.
