with the  30,000  shares of  Vertical  Computer  Systems  Preferred  Series  "C"
Convertible Stock ("Vertical Preferred C Stock").

      Whereas Vertical issued the Vertical Preferred C Stock to Enfacet and
currently owns 100% of Enfacet,

         Whereas,  the parties wish to resolve any outstanding issues concerning
the Vertical Preferred C Stock.

The parties hereby agree as follows:

1. The 15,000 shares of Vertical Preferred C Stock set aside for employees shall
be cancelled and Vertical,  subject to the terms of this agreement,  shall issue
within 120 days of the date of this Agreement, 3,000,0000 shares of common stock

         a.  Chuck Kensicki                 750,000

2. BUYER'S REPRESENTATIONS AND WARRANTIES.

         Each Buyer represents and warrants, severally and not jointly, that:

         (a)  INVESTMENT  PURPOSE.  Each  Buyer  is  acquiring  the  Convertible
Debentures  and,  upon  conversion  of  Convertible  Debentures,  the Buyer will
acquire the Conversion Shares then issuable,  for its own account for investment
only and not with a view towards,  or for resale in connection  with, the public
sale or distribution  thereof,  except pursuant to sales  registered or exempted
under the 1933  Act;  provided,  however,  that by  making  the  representations
herein, such Buyer reserves the right to dispose of the Conversion Shares at any
time in  accordance  with or pursuant  to an  effective  registration  statement
covering such Conversion Shares or an available exemption under the 1933 Act.

         (b) ACCREDITED INVESTOR STATUS. Each Buyer is an "ACCREDITED  INVESTOR"
as that term is defined in Rule 501(a)(3) of Regulation D.

                                        2

<PAGE>

         (c) RELIANCE ON EXEMPTIONS. Each Buyer understands that the Convertible
Debentures  are being offered and sold to it in reliance on specific  exemptions
from the registration requirements of United States federal and state securities
laws and that the Company is relying in part upon the truth and accuracy of, and
such Buyer's  compliance  with,  the  representations,  warranties,  agreements,
acknowledgments  and  understandings  of such Buyer set forth herein in order to
determine the  availability of such exemptions and the eligibility of such Buyer
to acquire such securities.

(d) INFORMATION.  Each Buyer and its advisors (and his or, its counsel), if any,
have been  furnished with all materials  relating to the business,  finances and
operations  of the  Company  and  information  he deemed  material  to making an
informed   investment   decision  regarding  his  purchase  of  the  Convertible
Debentures and the Conversion  Shares,  which have been requested by such Buyer.
Each Buyer and its advisors,  if any, have been afforded the  opportunity to ask
questions  of the Company and its  management.  Neither such  inquiries  nor any
other due diligence  investigations  conducted by such Buyer or its advisors, if
any, or its representatives  shall modify, amend or affect such Buyer's right to
rely on the  Company's  representations  and  warranties  contained in Section 3
below. Each Buyer understands that its investment in the Convertible  Debentures
and the  Conversion  Shares  involves a high degree of risk.  Each Buyer is in a
position   regarding  the  Company,   which,   based  upon  employment,   family
relationship  or economic  bargaining  power,  enabled and enables such Buyer to
obtain information from the Company in order to evaluate the merits and risks of
this investment. Each Buyer has sought such accounting, legal and tax advice, as
it has considered necessary to make an informed investment decision with respect
to its acquisition of the Convertible Debentures and the Conversion Shares.

         (e) NO  GOVERNMENTAL  REVIEW.  Each  Buyer  understands  that no United
States federal or state agency or any other  government or  governmental  agency
has  passed on or made any  recommendation  or  endorsement  of the  Convertible
Debentures  or the  Conversion  Shares,  or the fairness or  suitability  of the
investment in the Convertible Debentures or the Conversion Shares, nor have such
authorities  passed  upon  or  endorsed  the  merits  of  the  offering  of  the
Convertible Debentures or the Conversion Shares.

         (f) TRANSFER OR RESALE.  Each Buyer understands that except as provided
in the Investor  Registration Rights Agreement:  (i) the Convertible  Debentures
have not been  and are not  being  registered  under  the 1933 Act or any  state
securities laws, and may not be offered for sale, sold,  assigned or transferred
unless (A)  subsequently  registered  thereunder,  or (B) such Buyer  shall have
delivered to the Company an opinion of counsel, in a generally  acceptable form,
to the effect that such  securities to be sold,  assigned or transferred  may be
sold,  assigned or transferred  pursuant to an exemption from such  registration
requirements;  (ii) any sale of such  securities  made in  reliance  on Rule 144
under the 1933 Act (or a successor  rule thereto)  ("RULE 144") may be made only
in  accordance  with  the  terms  of Rule  144 and  further,  if Rule 144 is not
applicable,  any  resale of such  securities  under  circumstances  in which the
seller  (or the  person  through  whom the sale is made)  may be deemed to be an
underwriter  (as that term is  defined in the 1933 Act) may  require  compliance
with some other exemption under the 1933 Act or the rules and regulations of the
SEC there under; and (iii) neither the Company nor any other person is under any
obligation  to  register  such  securities  under  the  1933  Act or  any  state
securities  laws or to comply  with the terms and  conditions  of any  exemption
there under. The Company reserves the right to place stop transfer  instructions
against the shares and certificates for the Conversion Shares.

                                        3

         (g) LEGENDS.  Each Buyer  understands  that the  certificates  or other
instruments representing the Convertible Debentures and or the Conversion Shares
shall bear a restrictive  legend in substantially the following form (and a stop
transfer order may be placed against transfer of such stock certificates):

                  THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE HAVE NOT BEEN
                  REGISTERED  UNDER THE SECURITIES  ACT OF 1933, AS AMENDED,  OR
                  APPLICABLE  STATE  SECURITIES  LAWS. THE SECURITIES  HAVE BEEN
                  ACQUIRED  SOLELY FOR  INVESTMENT  PURPOSES AND NOT WITH A VIEW
                  TOWARD  RESALE  AND  MAY  NOT  BE  OFFERED  FOR  SALE,   SOLD,
                  TRANSFERRED  OR  ASSIGNED  IN  THE  ABSENCE  OF  AN  EFFECTIVE
                  REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES

                  STATE SECURITIES LAWS.

The  legend set forth  above  shall be removed  and the  Company  within two (2)
business days shall issue a certificate without such legend to the holder of the
Conversion  Shares upon which it is stamped,  if, unless  otherwise  required by
state securities laws, (i) in connection with a sale  transaction,  provided the
Conversion Shares are registered under the 1933 Act or (ii) in connection with a
sale  transaction,  after such holder  provides  the Company  with an opinion of
counsel,  which  opinion  shall be in form,  substance  and scope  customary for
opinions  of counsel in  comparable  transactions,  to the effect  that a public
sale,  assignment  or  transfer  of the  Conversion  Shares may be made  without
registration under the 1933 Act.

         (h)  AUTHORIZATION,  ENFORCEMENT.  This  Agreement  has  been  duly and
validly  authorized,  executed  and  delivered  on behalf of such Buyer and is a
valid and binding  agreement of such Buyer  enforceable  in accordance  with its
terms,  except as such  enforceability  may be limited by general  principles of
equity  or  applicable  bankruptcy,  insolvency,   reorganization,   moratorium,
liquidation  and other  similar laws  relating to, or affecting  generally,  the

person, it has been formed and validly exists and has not been organized for the
specific purpose of purchasing the Convertible  Debentures and is not prohibited
from doing so.

         (k) NO LEGAL ADVICE FROM THE COMPANY. Each Buyer acknowledges,  that it
had the opportunity to review this Agreement and the  transactions  contemplated
by this  Agreement  with his or its own legal  counsel  and  investment  and tax

conducted.  Each of the  Company and its  subsidiaries  is duly  qualified  as a
foreign corporation to do business and is in good standing in every jurisdiction
in which the nature of the  business  conducted  by it makes such  qualification
necessary,  except to the extent  that the failure to be so  qualified  or be in
good standing  would not have a material  adverse  effect on the Company and its
subsidiaries taken as a whole.

         (b) AUTHORIZATION,  ENFORCEMENT, COMPLIANCE WITH OTHER INSTRUMENTS. (i)
The Company has the  requisite  corporate  power and authority to enter into and

their terms,  except as such enforceability may be limited by general principles
of equity or  applicable  bankruptcy,  insolvency,  reorganization,  moratorium,
liquidation or similar laws relating to, or affecting generally, the enforcement
of  creditors'  rights and  remedies.  The  authorized  officer  of the  Company
executing this Agreement, the Investor Registration Rights Agreement, the Escrow
Agreement,   the  Irrevocable   Transfer  Agent  Instructions  and  any  related

approve,  before  issuance any press release or any other public  statement with
