                         VERTICAL COMPUTER SYSTEMS, INC.

                  Common Stock Purchase Warrant (the "Warrant")


            VERTICAL  COMPUTER  SYSTEMS,   INC.,  a  Delaware  corporation  (the
"Company"),  hereby  certifies that, for value  received,  Daniel  Benjamin,  or
registered assigns (the "Holder"),  is entitled,  subject to the terms set forth
below,  to purchase  from the Company at any time or from time to time up to and
including  Three (3) years  after the date  hereof,  and before  5:00 p.m.,  Los
Angeles  time,  on June 3, 2005,  One Million Two Hundred  Thousand  (1,200,000)
fully paid and nonassessable  shares of Common Stock,  $.00001 par value, of the
Company  (hereinafter  the  "Warrants") at an Exercise Price per share initially
equal to $0.003.  The  number of such  shares of Common  Stock and the  Exercise
Price are subject to adjustment as provided in this Warrant.

      1.  Conditions and Rights of Holder to Exercise Warrants.

      (a)   If,  from time to time,  the  Holder  acquires  any  shares of stock
pursuant to this Common Stock Purchase Warrant, the Holder accepts and agrees to
the  terms  of the  Lock  Up  Agreement,  attached  hereto  as  Exhibit  A,  and
incorporated herein by this reference.

      (b)   This  Warrant may be  exercised  by the Holder  hereof in full or in
part at any time or from time to time during the  exercise  period  specified in
the first paragraph  hereof,  by surrender of this Warrant and the  subscription
form annexed hereto (duly  executed) by such Holder to the Company and by making
payment,  in cash or by certified or official bank check payable to the order of
the Company or wire transfer to the Company's account or, with the prior written



consent of the Company,  through the surrender of previously  acquired shares of
Common  Stock at their fair  market  value on the  exercise  date or through the
execution of a  promissory  note  collateralized  by the shares  underlying  the
Warrant,  in the  amount  obtained  by  multiplying  (a) the number of shares of
Common  Stock  designated  by the  Holder  in the  subscription  form by (b) the
Exercise  Price  then in  effect.  On any  partial  exercise  the  Company  will
forthwith  issue and  deliver  to or upon the order of the  Holder  hereof a new
Warrant or Warrants of like tenor,  in the name of the Holder  hereof or as such
Holder  (upon  payment  by such  Holder of any  applicable  transfer  taxes) may
request,  providing  in the  aggregate  on the  face or  faces  thereof  for the
purchase  of the  number of shares of Common  Stock for which  such  Warrant  or
Warrants may still be exercised.

      2.    DELIVERY  OF  STOCK  CERTIFICATES,  ETC.,  ON  EXERCISE.  As soon as
practicable  after the  exercise of this  Warrant,  and in any event within five
business days thereafter,  the Company at its expense  (including the payment by
it of any  applicable  issue or stamp taxes) will cause to be issued in the name
of and delivered to the Holder  hereof,  or as such Holder (upon payment by such
Holder  of  any  applicable   transfer  taxes)  may  direct,  a  certificate  or
certificates  for the  number of fully paid and  nonassessable  shares of Common
Stock  to  which  such  Holder  shall  be  entitled  on such  exercise,  in such
denominations  as  may be  requested  by  such  Holder,  plus,  in  lieu  of any
fractional share to which such Holder would otherwise be entitled, cash equal to
such  fraction  multiplied  by the then  current  fair market  value of one full
share, together with any other stock or other securities any property (including
cash,  where  applicable)  to which such Holder is entitled  upon such  exercise
pursuant to Section 1 or otherwise.

      3.    DILUTION.

         a.    DIVIDENDS,  ETC. If the  Company  shall pay to the holders of its
Common Stock a dividend in shares of Common Stock or in  securities  convertible
into Common Stock, the Exercise Price in effect  immediately prior to the record
date fixed for the determination of the holders of Common Stock entitled to such
dividend  shall  be  proportionately  decreased,  effective  at the  opening  of
business on the next following full business day.

         b.    SPLITS,  COMBINATIONS,  ETC.  If  the  Company  shall  split  the
outstanding  shares  of its  Common  Stock  into a  greater  number of shares or
combine the  outstanding  shares into a smaller  number,  the Exercise  Price in
effect  immediately prior to such action shall be  proportionately  decreased in
the case of a split or increased in the case of a combination,  effective at the
opening of business on the full business day next  following the day such action
becomes effective.

      4.    PROTECTION  IN  CASE  OR  RECLASSIFICATION,  ETC.  In  case  of  any
reclassification  or change of the terms of the outstanding  shares of the class
of Common Stock  issuable upon the exercise of this Warrant,  then upon exercise
of this Warrant (other than a change  relating to par value, or as a result of a
subdivision or  combination),  or in case of any  consolidation or merger of the
Company with or into another  company  (other than a merger in which the Company
is the continuing  company or which does not result in any  reclassification  or



change of outstanding shares of Common Stock of the class issuable upon exercise
of this Warrant, other than a split or combination of shares), or in case of any
sale or conveyance to any other person or entity of all or substantially  all of
the assets of the Company,  the Company shall use its best efforts to execute an
agreement  providing  that the  holder  of this  Warrant  shall  have the  right
thereafter  to exercise  this Warrant for the kind and amount of shares of stock
and other securities and property receivable upon such reclassification, change,
dividend, distribution, consolidation, merger, sale or conveyance by a holder of
the number of shares of Common Stock of the Company for which this Warrant might
have  been  exercised  immediately  prior  to  such  reclassification,   change,
dividend, distribution,  consolidation, merger, sale or conveyance. This Section
4 shall apply to successive  reclassifications  and changes of and dividends and
distributions  on  shares  of Common  Stock  and to  successive  consolidations,
mergers,  sales  or  conveyances.  Notice  of the  execution  of  any  agreement
pertaining   to   such   reclassification,   change,   dividend,   distribution,
consolidation,  merger,  sale or conveyance shall be given to the holder of this
Warrant as soon as practicable  and in any event not less than ten (10) business
days before any such transaction is consummated.

      5.    RESERVATION OF STOCK,  ETC.,  ISSUABLE ON EXERCISE OF WARRANTS.  The
Company will at all times  reserve and keep  available,  solely for issuance and
delivery on the exercise of this  Warrant,  all shares of Common Stock from time

      6.    REGISTER OF WARRANTS.  The Company shall maintain,  at the principal

      7.    EXCHANGE  OF  WARRANT.  This  Warrant  is  exchangeable,   upon  the
surrender  hereof by the Holder  hereof at the  office or agency of the  Company
referred  to in  Section  6,  for  one  or  more  new  Warrants  of  like  tenor
representing in the aggregate the right to subscribe for and purchase the number
of shares of Common Stock which may be subscribed for purchase  hereunder,  each
of such new Warrants to represent  the right to subscribe  for and purchase such
number of shares as shall be  designated  by said  Holder  hereof at the time of
such surrender.

      8.    REPLACEMENT   OF  WARRANT.   On  receipt  of   evidence   reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this Warrant  and, in the case of any such loss,  theft or  destruction  of this
Warrant,   on  delivery  of  an  indemnity   agreement  or  security  reasonably
satisfactory  in form and  amount  to the  Company  or,  in the case of any such
mutilation,  on surrender and  cancellation of this Warrant,  the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor.

Common Stock on the exercise of this  Warrant  pursuant to Section 1,  redeeming
this Warrant  pursuant to Section 2, exchanging this Warrant pursuant to Section
7, and replacing  this Warrant  pursuant to Section 8, or any of the  foregoing,
and thereafter any such issuance,  exchange or replacement,  as the case may be,
shall be made at such office by such agent.

      10.   NO RIGHTS OR LIABILITIES  AS A  STOCKHOLDER.  This Warrant shall not
entitle the Holder  hereof to any voting rights or other rights as a stockholder
of the Company, until properly exercised.

      11.   NOTICES.  All notices and other  communications  from the Company to
the registered  Holder of this Warrant shall be mailed by first class  certified

in  writing  by such  Holder  or at the  address  shown  for such  Holder on the
register of Warrants referred to in Section 6.

      12.   Miscellaneous.  This  Warrant  and any terms  hereof may be changed,
waived,  discharged or terminated only by an instrument in writing signed by the
party against which enforcement or such change, waiver, discharge or termination
is sought.  This Warrant shall be construed and enforced in accordance  with and
governed by the  internal  laws of the State of  Delaware.  The headings in this
Warrant are for  purposes of  reference  only,  and shall not limit or otherwise
affect  any of the terms  hereof.  The  invalidity  or  unenforceability  of any
provision  hereof shall in no way affect the validity or  enforceability  of any
other provision.

      13.   "PIGGY-BACK" REGISTRATION.

      a.    Grant of Right.  The Holder of this Warrant shall have the right for
a period of five years from the date of grant of this  Warrant to include all or
any part of this Warrant and the shares of Common Stock  underlying this Warrant
(collectively,  the  "Registrable  Securities")  as part of any  registration of
securities  filed by the Company  (other than in  connection  with a transaction
contemplated by Rule 145(a) promulgated under the Act); provided,  however, that
if,  in  the  written   opinion  of  the  Company's   managing   underwriter  or
underwriters,  if any,  for such  offering  determines  that  marketing  factors
require a limitation  of the number of shares to be  underwritten,  the managing
underwriter  in  its  sole  discretion  may  limit  the  number  of  Registrable
Securities  to be  included  in the  registration,  or may  exclude  Registrable
Securities  entirely from such registration.  In such case, the Company shall so
advise Holder whose Registrable  Securities  otherwise would be included in such
registration  and  underwritten  offering shall be allocated among other selling
shareholders requesting registration in proportion, as nearly as practicable, to
the respective amounts of Registrable  Securities held by Holder and registrable
shares  each of such  other  selling  shareholders  at the date of filing of the
Registration Statement. If Holder disapproves of the terms and conditions of the
underwritten  offering,  Holder may withdraw  therefrom by written notice to the
Company and the managing underwriter(s).  Any Registrable Securities excluded or
withdrawn  from  such  underwritten   offering  shall  be  withdrawn  from  such
registration.

      b.    Lock Up.  Holder hereby agrees that, if requested by the Company and
the managing  underwriter(s),  it will enter into a customary  form of "lock-up"
agreement with the Company and the managing  underwriter(s)  with respect to any
Registrable  Securities then held by Holder,  which agreement shall contain such
Registrable  Securities  than those  contained in any other such agreements then
entered  into  by  the  Company  and  the  managing  underwriter(s)  with  other
comparable holders of the Company's Common Stock.

      c.    Terms.  The Company  shall bear all fees and  expenses  attendant to
registering the Registrable Securities, including any filing fees payable to the
National  Association of Securities  Dealers,  Inc. (NASD), but the Holder shall
pay any and all  underwriting  commissions and the expenses of any legal counsel
selected  by the  Holder  to  represent  it in  connection  with the sale of the
Registrable  Securities.  In the  event  of such a  proposed  registration,  the
Company shall furnish the then Holder of outstanding Registrable Securities with
prompt written notice prior to the proposed date of filing of such  registration
statement.  Such  notice  to the  Holder  shall  continue  to be given  for each
registration  statement  filed  by the  Company  until  such  time as all of the
Registrable  Securities  have  been  sold  by  the  Holder.  The  Holder  of the
Registrable  Securities  shall  exercise the  "piggy-back"  rights  provided for
herein by giving  written  notice,  within  twenty  days of the  receipt  of the
Company's  notice of its  intention to file a  registration  statement.  Nothing
contained in this Warrant shall be construed as requiring any Holder to exercise
this Warrant or any part thereof prior to the initial filing of any registration
statement  or the  effectiveness  thereof.  The Company  shall have the right to
terminate  or withdraw  any  registration  initiated  by the Company  under this
Section 5 prior to the effectiveness of such registration  whether or not Holder
has elected to include Registrable Securities in such registration.

IN WITNESS WHEREOF,  Vertical Computer  Systems,  Inc. has caused this Warrant
to be executed on its behalf by one of its officers thereunto duly authorized.

                                LOCK-UP AGREEMENT

      The undersigned  individual hereby agrees,  for a period of 12 (12) months
from June 3, 2002 (the  "LOCK-UP  PERIOD"),  not to offer to sell,  contract  to
sell,  or  otherwise  sell,  dispose of,  loan,  pledge or grant any rights with
respect to  (collectively,  a  "DISPOSITION")  any shares of  VERTICAL  COMPUTER
SYSTEMS,  INC.  ("Company"),  Common  Stock  ("Common  Stock"),  any  options or
warrants to purchase  any shares of Common Stock or any  securities  convertible
into or exchangeable  for shares of Common Stock  (collectively,  "SECURITIES"),
now owned or hereafter  acquired directly by the undersigned  individual or with
respect to which undersigned  individual has or hereafter  acquires the power of
disposition  pursuant to the warrant,  dated,  "Date of Grant>> (the "Warrant"),
otherwise than:

(i)         as a bona fide gift or gifts,  provided the donee or donees  thereof
            agree to be bound by these Lock-Up provisions;
(ii)        as a  distribution  to  limited  partners  or  shareholders  of  the
            undersigned, provided that the distributees thereof agree in writing

            to these Lock-Up Provisions,  of (a) no more on any trading day than
            15,000  shares (which amount is calculated by dividing the number of
            shares,  1,200,000 shares currently held by the undersigned employee
            pursuant to the Warrant by the number of trading  days in a 12 month
            period [240 days], and multiplying that resultant by three),  and no
            more during any calendar month than (b) 100,000 shares (which amount
            is  calculated by dividing the 1,200,000  shares  currently  held by
            undersigned  individual  by 12 months);  however,  in the event that
            these shares are subject to a stock split or a reverse  stock split,

Securities from engaging in any hedging or other  transaction  which is designed
to or reasonably  expected to lead to or result in a  Disposition  of Securities
during the  Lock-Up  Period,  even if such  Securities  would be  disposed of by
someone other than the undersigned individual.  Such prohibited hedging or other
transactions  would include  without  limitation  any short sale (whether or not

includes,  relates  to or  derives  any  significant  part of its value from the
Securities.

      The undersigned individual hereby agrees and consents: (i) to the entry of
stop  transfer  instructions  with the  Company's  transfer  agent  against  the

                        EXPLANATION OF LOCK-UP PROVISIONS

The Company is requesting all employees,  advisors and other  pertinent  parties
(collectively "Insiders") to execute the attached Lock-Up Provisions Document in
order to protect the  Company's  share price on its trading  market  (NASDAQ OTC
Bulletin Board) from being unduly depressed by sales transactions by insiders.

The provisions  are designed to allow  Insider-shareholders  to sell  reasonable
amounts of Company  shares  without  disrupting  the market for Company  shares.
Obviously,  if a significant number of shares are sold within a relatively short
period of time, the effect is to lower the Company's  market price. It is in the
best interest of the Company and all of its  shareholders  to assist in creating
an "orderly" market, where sales will not, in general,  significantly impact the
Company's share price. It is very difficult, indeed, to sustain the market price
of the Company's shares,  let alone increase the market price after an ill-timed
sell-off of Company shares by Insiders or others.

The attached provisions allow an Insider to sell shares (i.e., those eligible to
be sold in the stock  market) in equal monthly  amounts over a 24-month  period.
The provisions  further limit any  single-day  sale equal to 3 times the average
"permitted daily sale" of 1/20th of the permitted  monthly amount.  For example:
an Insider holding 1,000,000 shares eligible for sale would be permitted to sell
up to a total of 41,667 shares per month (1,000,000  shares/24 months),  limited
to an average daily sale of 2,083 shares (41,667  shares/20  days).  The highest
permitted daily sale in any month would be 6,250 shares (2,083 shares x 3).

Note that the provisions allow an Insider to sell more shares than are permitted
under the  formulae  with written  Company  permission  in order to  accommodate
emergency and hardship situations.
