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  the day that is Three (3) years after the date that is the earlier of

shares of Common  Stock,  $.00001  par value,  of the Company  (hereinafter  the
"Warrants")  at an Exercise  Price per share  initially  equal to $_______.  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

<PAGE>

         (c) 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.

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

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

<PAGE>

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.

Dated:   _________2, 200___         VERTICAL COMPUTER SYSTEMS, INC.

                                LOCK-UP AGREEMENT

         The undersigned  individual hereby agrees,  for a period of twelve (12)
months from __________, ___, 200__ (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 be bound by the terms of these Lock-Up provisions;
         (iii)    in a brokerage  transaction,  for all persons  holding  shares
                  subject  to these  Lock-Up  Provisions,  of (a) no more on any
                  trading day than ______  shares (which amount is calculated by
                  dividing  the number of shares,  __________  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)__________  shares (which amount is
                  calculated by dividing the __________ shares currently held by
                  undersigned  individual  by 12  months);  in  the  event  that
                  Grantee  does not sell shares  above the monthly  limit in any
                  one month,  these  remaining  amounts shall be cumulative  and
                  carry on to subsequent months thereby increasing the allowable
                  amounts to be sold;  however,  in the event that these  shares
                  are subject to a stock  split or a reverse  stock  split,  the

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
against the box) or any purchase,  sale or grant of any right (including without
limitation  any put or call  option)  with  respect  to any  Securities  or with
respect to any security  (other than a broad-based  market basket or index) that
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
transfer of the Securities  held by the  undersigned  except in compliance  with
this Agreement,  and (ii) to furnish the Company brokerage account statements or
trade confirmations which evidence compliance with this Agreement.

4. DEFAULT;  REMEDIES.  Each of the following  occurrences and conditions  shall

obligation to pay money, as and when performance of such obligation is due under
this Note or Loan Documents which failure  continues for fifteen (15) days after
notice thereof from Promissee to Promissor; or

         c.  Promissor's  making or at any time having made any  representation,

anything to the contrary  herein or  elsewhere,  the entire  amount of principal
then  outstanding  under this Note and all interest,  fees,  charges,  and other
amounts  owing  and then  unpaid  hereunder  shall  become  immediately  due and
payable,  and  Promissee  may exercise any and all rights that it may have under
