     THIS EXCHANGE  AGREEMENT (the  "Agreement")  is made and entered into as of
the 26th of June,  2002,  by and among (i) MDSI Mobile Data  Solutions,  Inc., a
Canadian corporation ("MDSI"); (ii) Richard S. Waidmann ("Waidmann") and Eric Y.
Miller ("Miller," and collectively with Waidmann, the "Shareholders"), residents
of  the  State  of  Missouri;  and  (iii)  Connectria  Corporation,  a  Missouri
corporation ("Connectria").

                                    RECITALS

     A.   Pursuant to an Agreement and Plan of  Reorganization,  dated as of May
9, 2000 (the "Reorganization  Agreement"),  MDSI acquired all of the outstanding
voting  securities  of  Connectria  by a merger of a subsidiary of MDSI with and
into Connectria as the surviving  corporation (the "Merger") in a reorganization
pursuant to Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code").

     B.   The  Shareholders,  who  collectively  owned 97.6% of the  outstanding
common  stock  of  Connectria  immediately  prior  to the  Merger,  received  an
aggregate of 824,700 shares of common stock of MDSI as the consideration for the
Merger (the "MDSI Shares").

     C.   MDSI  and  the  Shareholders  have  reached  a  mutual   understanding
concerning  the unwinding of MDSI's  acquisition  of  Connectria,  through (i) a
distribution  by MDSI to the  Shareholders  of one hundred percent (100%) of the
outstanding  voting  securities  of  Connectria  and  (ii) the  transfer  by the
Shareholders to MDSI of the MDSI Shares, in a transaction intended to qualify as
a tax-deferred transaction pursuant to Section 355 of the Code.

     D.   MDSI  and the  Shareholders  have  reached  additional  understandings
concerning (a) the terms of a mutual release among the parties, (b) the existing
indebtedness of Connectria to MDSI, (c) certain indebtedness of the Shareholders
to MDSI, (d) the options for common stock of MDSI held by the Shareholders,  and
(e) certain other matters,  all as more specifically set forth in this Agreement
or in the other  agreements  having  their  forms  attached  as exhibits to this
Agreement.

     NOW, THEREFORE,  in consideration of these premises,  the  representations,
warranties,  covenants  and  agreements  herein  contained,  and other  good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  hereby  are
acknowledged, the parties hereto agree as follows:

     1.   Amendment of Connectria's Articles of Incorporation and Bylaws. Within
five (5) days after the date of this Agreement,  MDSI shall take all appropriate
action to cause Article III of the Articles of Incorporation of Connectria to be
amended (i) to authorize  the issuance of up to one hundred  thousand  (100,000)
shares of preferred stock, par value .01 per share (the "Preferred Stock"),  and
(ii) to  authorize  the Board of  Directors  of  Connectria,  by  resolution  or
resolutions,  at any time and from time to time,  to divide and establish any or
all of the  unissued  shares of  Preferred  Stock into one or more  series  and,
without  limiting the  generality  of the  foregoing,  to fix and  determine the
designation of each such share, the number of shares which shall constitute such
series and certain powers,  preferences and relative participating,  optional or
other special rights and  qualifications,  limitations  and  restrictions of the
shares of each series so

<PAGE>

established (such amendment, the "Charter Amendment").  In addition, the parties
hereto  shall  cause the  bylaws of  Connectria  to be  amended to include a new
Article __ containing  restrictions on the transferability of shares of stock of
Connectria,  such Article to be in form and substance  mutually  satisfactory to
the parties hereto.

     2.   Establishment  of Series of Nonvoting  Preferred  Stock.  Concurrently
with or  immediately  following the proper filing of the Charter  Amendment with
the office of the Secretary of State of Missouri, MDSI shall cause Connectria to
establish,  by all appropriate board action, a series of Preferred Stock, with a
maximum issue of 50,380 shares, to be known as the "Series A Nonvoting Preferred
Stock," and having the  preferences  and relative  rights,  and  qualifications,
limitations and restrictions,  set forth in Exhibit A attached to this Agreement
(the "Series A Designations").

     3.   Capital  Contributions and Warrant.  Immediately  following the proper
filing of the Series A Designations with the office of the Secretary of State of
Missouri, MDSI shall take all appropriate action to contribute to the capital of
Connectria  the principal  amount of the $2,519,000  indebtedness  of Connectria
(the "Contributed Debt"). In recognition of such contribution,  MDSI shall cause
Connectria  to issue to MDSI a warrant to purchase up to 50,380 shares of Series
A Nonvoting  Preferred Stock,  such warrant to have the exercise price,  rights,
expiration  date and  other  terms  set  forth in  Exhibit  B  attached  to this
Agreement (the "Warrant").  Concurrently therewith, MDSI shall contribute to the
capital of  Connectria  all of MDSI's  right,  title and  interest in and to its
notes  receivable  from Waidmann (in the principal  amount of $150,000) and from
Miller (in the principal  amount of $100,000),  and no additional  securities of
Connectria shall be issued to MDSI in respect of such contribution.

     4.   Working Capital Loan and Services Agreement.  Immediately prior to the
Closing (as defined in Section 5 below), MDSI shall take the following actions:

          (a)  MDSI  shall  lend  to  Connectria  the sum of Two  Hundred  Fifty
Thousand Dollars  ($250,000),  which loan (i) shall be evidenced by a promissory
note of Connectria having the interest rate, repayment terms and other terms set
forth in Exhibit C attached to this Agreement (the "MDSI Note"),  and (ii) shall
be secured by a security  interest  in the assets of  Connectria  which shall be
subordinate   and  junior  in  right  of  payment  to  any  present  and  future
indebtedness of Connectria for borrowed money to a financial  institution taking
a  security  interest  or  other  lien on  substantially  all of the  assets  of
Connectria,  pursuant to a Subordinated  Security Agreement in the form attached
as Exhibit D to this Agreement (the "Subordinated Security Agreement").

          (b)  MDSI and  Connectria  shall enter into an  agreement  for hosting
services to be provided by Connectria  to MDSI (and  providing for the return of
certain servers and accounting  systems from Connectria to MDSI),  having a term
of five (5) years and otherwise  having the terms set forth in a mutually agreed
upon Services  Agreement at terms no less  favorable  than those provided to any
other customer of Connectria for such services, and MDSI shall pay to Connectria
the sum of  $250,000  in  prepayment  of the  services to be provided to MDSI by
Connectria during the term of the Services Agreement.

     5.   Exchange at Closing.  Subject to the terms and conditions set forth in
this  Agreement,  on July 15,  2002 or such  other  date (no later than July 31,
2002) as the parties shall

ordinary course of business consistent with past practice,  and each of MDSI and
the  Shareholders  shall  continue  to provide  the same level of  services  and
assistance  as has been  provided by such  parties to  Connectria  in the period
preceding the date of this Agreement.  Neither MDSI nor the  Shareholders  shall
take, or cause  Connectria to take,  any action to distribute any cash dividends
or other assets to MDSI or to repay any  indebtedness  of Connectria to MDSI, or
any other action that is  inconsistent  with the  purposes of this  Agreement or
that could reasonably be expected to have an adverse impact on Connectria or its
assets, liabilities, condition (financial or otherwise), business or prospects.

          (b)  Prior  to  Closing,   each  party  shall  use  all   commercially
reasonable  efforts to fulfill the  conditions to Closing  which are  reasonably
within such party's control.

          (c)  Prior to carrying out the actions  required in Sections 1 through
4 of this  Agreement,  MDSI shall furnish to  Shareholders  for their review and
approval  copies  of any  document  or  instruments  to be  executed  by MDSI or
Connectria in connection therewith (to the extent the forms of such documents or
instruments  are  not  attached  as  exhibits  to  this   Agreement),   and  the
Shareholders  shall not  unreasonably  withhold or delay their  approval of such
documents.

          (d)  From and after Closing,  the Shareholders  shall cause Connectria
to use all  commercially  reasonable  efforts  to  terminate,  or to obtain  the
release of MDSI from,  the $1,000,000 in loan  guarantees  and equipment  leases
made by MDSI on behalf of  Connectria,  as  identified in Schedule 6(g) attached
hereto.

          (e)  The  parties  acknowledge  that  the  transactions  occurring  at
Closing are intended to qualify as a tax-deferred  transaction under Section 355
of the Internal  Revenue Code of 1986, as amended (the "Code"),  and the parties
shall not take any  position  on any tax return or  information  return  that is
inconsistent with such position.  Notwithstanding the foregoing,  however,  each
party  acknowledges that such party is relying on its or his own tax advisors in
connection  with,  and is  solely  responsible  for  its or his  respective  tax
consequences arising from, the transactions  contemplated by this Agreement, and
no  party  makes  any  warranty  or  representation  with  respect  to  the  tax
consequences of such  transactions  to any party to this Agreement.  The parties
will  continue to take the position on all tax returns and  information  returns
that the Merger was a  tax-deferred  reorganization  under Section 368(a) of the
Code.

          (f)  Connectria  shall  withhold  all amounts  required to be withheld
under  United  States tax  withholding  laws with respect to (i) the stated five
percent (5%) dividend  payments on the Series A Nonvoting  Preferred Stock, (ii)
interest  payments under the MDSI Note, and (iii) other payments if (and only to
the extent that) changes in applicable tax laws, in published interpretations of
any applicable taxing authority or court, or in the United  States-Canada Income
Tax Treaty subsequent to the date of this Agreement impose a legal obligation

                                     - 9 -
<PAGE>

on  Connectria  to withhold.  If any amounts are withheld by  Connectria  on any
payment or transaction contemplated by this Agreement, the Warrant or the Series
A Nonvoting  Preferred  Stock  (other than  amounts  permitted to be withheld by
Connectria  as  provided  in  clauses  (i),  (ii) and  (iii) of the  immediately
preceding  sentence),  Connectria shall bear the full burden of such withholding
tax, and any such payment to MDSI shall not be reduced for such withholding tax.

          (g)  MDSI shall not withhold any amount under Canadian tax withholding
laws with respect to the distribution of Connectria Common Stock to Waidmann and
Miller  in  exchange  for their  shares of and  options  for MDSI  Common  Stock
pursuant to the transactions contemplated by this Agreement,  except only to the
extent  changes  in  applicable  tax laws and  interpretations  or in the United
States-Canada  Income Tax Treaty subsequent to the date of this Agreement impose
a legal  obligation on MDSI to withhold);  and if any amounts are required to be
withheld by MDSI on any such  distribution  or transaction  contemplated by this
Agreement  (other  than  amounts  permitted  to be  withheld  by MDSI  under the
foregoing  exception),  MDSI shall bear the full burden of such  withholding tax
and any such  distribution  to Waidmann and Miller shall not be reduced for such
withholding tax.

          (h)  MDSI  acknowledges  and  agrees  that (i) the  fair  value of the
Warrant to be received by it  pursuant  to this  Agreement  is not less than the
fair value of the  Contributed  Debt,  and (ii) the fair value of the Connectria
Common Stock to be  distributed to the  Shareholders  pursuant to this Agreement
has been  valued by MDSI not to  exceed  Four  Million  Eight  Hundred  Thousand
Dollars ($4,800,000).  No party to this Agreement shall take any position on any
tax return or  information  return  that is  inconsistent  with the  immediately
preceding  sentence.  Each party to this Agreement  acknowledges and agrees that
the  consideration  paid and to be paid to such party under this Agreement has a
fair value reasonably equivalent to the value of the securities and other rights
to be surrendered by such party under this Agreement.

          (i)  Connectria acknowledges and agrees that the trademark and service
mark "eService," the domain  "eService.com" and the items of equipment listed on
Schedule 10(i) hereto are the property of MDSI and all items of equipment  shall
be returned to MDSI upon request and will be maintained  in accordance  with the
Services Agreement.

     11.  Taxes, Returns and Adjustments.

          (a)  MDSI, at its expense (to the extent such expense is not reflected
in the Closing Financial Statements, as defined below), shall be responsible for
causing the  preparation,  signing and filing of all of Connectria's tax returns
for all tax periods ending after the closing date of the Merger and on or before
the Effective Date to the extent such tax returns are due prior to the Effective
Date  (with  regard  to   extensions).   Such  tax  returns  shall  be  prepared
consistently  with  MDSI's and  Connectria's  historical  practices.  MDSI shall
permit the Shareholders,  or their designee,  to review and comment on, prior to
filing,  any such tax return.  The preparation  and filing of any U.S.  federal,
state,  foreign or local  government  tax return for  Connectria for (i) any tax
period ending prior to the  Effective  Date to the extent such tax return is due
after the Effective  Date (taking into account any valid  extensions),  and (ii)
any tax period that straddles the Effective Date, shall be the responsibility of
Connectria and the  Shareholders.  Connectria shall not amend or modify, or take
any  position  inconsistent  with,  such tax returns  without the prior  written
consent  of  MDSI,  which  consent  may  be  withheld  in its  sole  discretion.

                                     - 10 -
<PAGE>

Connectria and the Shareholders  shall fully cooperate with MDSI with respect to
the preparation, signing and filing of such Connectria tax returns.

          (b)  To the extent  accrued  and  unpaid  taxes are not  reflected  on
Connectria's  financial  statements as of the Effective Date prepared by MDSI in
accordance with generally  accepted  accounting  principles in the United States
(the "Closing Financial Statements"),  MDSI shall be liable for, shall indemnify
and hold  Connectria  and the  Shareholders  harmless  against,  and shall  make
payment of, any foreign,  U.S.  federal,  state and local taxes,  including  any
interest and penalties,  payable by Connectria for all tax periods of Connectria
or portions thereof ending after the closing date of the Merger and on or before
the  Effective  Date,  whether or not such taxes were shown on any tax return of
Connectria for such periods, including any tax liability of Connectria resulting
from any audit or other adjustment by any taxing authority to any tax returns in
respect of such periods.  MDSI shall be entitled to any refunds of taxes for any
such tax period to the extent such refunds are paid to Connectria. MDSI shall be
liable for and shall indemnify Connectria for any interest and penalties imposed
by reason of any underpayment of estimated taxes in respect of any tax period of
Connectria  that  straddles the Effective  Date to the extent such estimated tax
payments  were due on or prior to the  Effective  Date.  Connectria  will  fully
cooperate  with MDSI,  and will  provide  MDSI with full access to  Connectria's
books and records,  with  respect to the  preparation  of the Closing  Financial
Statements.

          (c)  From and after the Effective Date, the  Shareholders,  Connectria
and MDSI  shall  give  prompt  notice  to each  other of any  proposed  audit or
adjustment by any taxing authority to taxes of Connectria for all tax periods of
Connectria  that end after the  closing  date of the Merger and on or before the
Effective Date or that straddle the Effective Date. MDSI, at its expense,  shall
be responsible for, and control, any audits of any returns filed (or required to
be filed) by Connectria  with respect to any tax period of Connectria  that ends
after the  closing  date of the  Merger  and on or before  the  Effective  Date,
provided that Connectria or the Shareholders,  at their expense, may participate
in any such audit.  MDSI shall not settle or  compromise  any such audit without
the prior  written  consent  of the  Shareholders,  which  consent  shall not be
unreasonably withheld. Connectria, at its expense, shall be responsible for, and
control,  any audits of any returns (i) for all tax periods of  Connectria  that
straddle the  Effective  Date and (ii) all tax periods of  Connectria  beginning
after the Effective  Date.  Connectria  shall not settle or compromise any audit
for any period referred to in clause (i) of the immediately  preceding  sentence
without  the  prior  written  consent  of  MDSI,  which  consent  shall  not  be
unreasonably withheld.

     12.  Limitation on Transfers of Securities.

          (a)  From and after the Closing Date, neither the Warrant,  the Series
A Nonvoting  Preferred Stock  receivable upon exercise  thereof nor any interest
therein (the "Securities") shall be transferable except upon satisfaction of the
relevant conditions  specified in this Section 11, which conditions are intended
to ensure  compliance  with the  provisions of the  Securities  Act of 1933 (the
"Securities  Act") in respect of the  transfer of any of the  Securities  or any
interest therein.  MDSI will cause any proposed transferee of the Securities (or
of any interest  therein)  held by it to agree to take and hold such  Securities
(or any interest  therein)  subject to the  provisions  and upon the  conditions
specified in this Section 12.

                                     - 11 -
<PAGE>

          (b)  Each certificate for Securities issued to MDSI or to a subsequent
transferee shall (unless  otherwise  permitted by the provisions of this Section
12) include a legend in  substantially  the  following  form, in addition to any
other legend that may be required by law:

     THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN  REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED,  OR QUALIFIED UNDER ANY STATE
     SECURITIES   LAWS.   SUCH   SECURITIES   MAY  NOT  BE  SOLD,   TRANSFERRED,
     HYPOTHE-CATED  OR OTHERWISE  ASSIGNED EXCEPT PURSUANT TO (i) A REGISTRATION
     STATEMENT  RELATING TO THE  SECURITIES  WHICH IS EFFECTIVE  UNDER SUCH ACT,
     (ii) RULE 144 OR 144A  UNDER  SUCH ACT,  OR (iii) AN  OPINION OF COUNSEL OR
     OTHER EVIDENCE  SATISFACTORY  TO THE  CORPORATION,  TO THE EFFECT THAT SUCH
     SALE, TRANSFER, HYPOTHECATION OR OTHER ASSIGNMENT IS IN COMPLIANCE WITH THE
     PROVISIONS OF SUCH ACT.

          (c)  Notice of Proposed  Transfers.  Not less than three business days
prior to any proposed transfer of any Securities  bearing the restrictive legend
set forth in Section  12(b) or any interest  therein,  the holder  thereof shall
give written  notice to  Connectria  of such  holder's  intention to effect such
transfer, setting forth the manner and circumstances of the proposed transfer in
reasonable  detail.  Any such proposed  transfer which is not made pursuant to a
registration  statement  filed under the  Securities Act may be effected only if
the MDSI shall have  received  such  notice of  transfer  accompanied  by (i) an
opinion of counsel,  representation  letter or other written evidence reasonably
satisfactory  to  Connectria,  addressed to  Connectria,  to the effect that the
proposed  transfer of such  Securities or such interest  therein may be effected
without  registration of such Securities  under the Securities Act. In addition,
if the holder of the  Securities  delivers to  Connectria  an opinion of counsel
reasonably   satisfactory  to  Connectria  that  subsequent  transfers  of  such
Securities will not require  registration  under the Securities Act,  Connectria
will promptly after such contemplated transfer deliver new certificates for such
Securities  that do not bear the legend set forth in Section 12(b) above. If the
foregoing  conditions entitling the holder to effect a proposed transfer of such
Securities without registration have not been satisfied, the holder in each case
will not transfer the Securities  proposed to be transferred.  Each  certificate
evidencing  the  Securities   transferred  as  above  provided  shall  bear  the
appropriate legend set forth in Section 12(b), and each agreement  purporting to
transfer any interest in any of the Securities shall bear a similar legend.

     13.  Miscellaneous.

          (a)  Notices.   All  notices  and  other   communications  under  this
Agreement  shall be in writing and shall be deemed given (a) when such notice is
personally  delivered,  (b)  five  (5)  days  after  dispatch  by  certified  or
registered  mail,  return  receipt  requested,  (c) two (2) business  days after
dispatch by a reputable  overnight delivery service, or (d) upon transmission by
facsimile machine,  provided an answerback is received and provided further that
notice is confirmed by any other permissible method.  Notices shall be addressed
to such party at its address hereinafter set forth or such other address as such
party may hereafter specify by notice given pursuant to this Section 13(a).

Company,  the Company shall pay to the holders of the Series A Preferred  Stock,
out of the assets of the Company  available  for the payment of dividends  under
the GBCL, preferential dividends at the times and in the amounts provided for in
this paragraph 2 and no more.  Dividends  shall be paid by mailing the Company's
good check in the proper  amount to each holder of the Series A Preferred  Stock
to such holder at such holder's address as it appears on the Company's  register

Funds and Assets")  shall be distributed  to the Company's  shareholders  in the
following manner:

          (a)  Priority.  The holders of Series A Nonvoting Preferred Stock then
outstanding shall be entitled to be paid, out of the Available Funds and Assets,
and prior and in preference to any payment or distribution (or any setting apart
of any payment or  distribution) of any Available Funds and Assets on any shares

recapitalizations  or the like) plus all  declared  but unpaid  dividends on the
shares of Series A Nonvoting  Preferred  Stock held by such  holder,  if any. If
upon any  liquidation,  dissolution or winding up of the Company,  the Available
Funds and Assets shall be  insufficient  to permit the payment to all holders of
the  Series  A  Nonvoting  Preferred  Stock of their  full  preferential  amount
described in this Section 3(a),  then all of the remaining  Available  Funds and
Assets shall be distributed among the holders of the then outstanding  shares of
Series A  Nonvoting  Preferred  Stock  pro  rata,  according  to the  number  of
outstanding  shares  of Series A  Nonvoting  Preferred  Stock  then held by each
holder thereof.

to be a liquidation, dissolution or winding up of the Company as those terms are
used in Section 3(a):  (i) An  acquisition  of the Company by another  entity by
means of any transaction or series of related transactions  (including,  without
limitation,  any reorganization,  merger or consolidation) pursuant to which the
Company's  shareholders  immediately  prior to such  transaction  or  series  of
related  transactions  own immediately  following such  transaction or series of
related  transactions,  less  than 50% of the  outstanding  voting  power of the
resulting entity, and (ii) the sale of all or substantially all of the assets of
the Company.  Holders of shares of Series A Nonvoting  Preferred  Stock shall be
given  notice of any such  transaction  set forth in this Section 3(b) not later
than the  earlier of (A) 10 days prior to the  shareholders'  meeting  called to
approve  the  transaction,  and  (B) 20  days  prior  to  the  closing  of  such
transaction  (such  notice  shall be deemed  given  upon the  earlier  of actual
receipt  thereof or deposit  thereof in the United  States mail, by certified or
registered mail, return receipt  requested,  postage prepaid,  addressed to each
holder of record at the  address of such  holder  appearing  on the books of the
Company).

          (c)  Non-Cash Consideration.  If any assets of the Company distributed
to shareholders in connection with any liquidation, dissolution or winding up of
the Company are other than cash, then the value of such non-cash assets shall be
deemed to be their fair market value as determined in good faith by the Board.

     4.   Voting  Rights.  Holders of  outstanding  shares of Series A Nonvoting
Preferred  Stock shall not be entitled to vote in the  election of  directors of
the Company or on any other matter coming to the  attention of the  shareholders
of the Company.

          (f)  The Board  shall  have full  power and  authority  subject to the
limitations and provisions herein contained to prescribe the manner in which and
the terms and conditions upon which the Series A Nonvoting Preferred Stock shall

          (g)  Any notice  required by the  provisions  of this  Section 5 to be

     (a) Ownership of this Warrant. The Company may deem and treat the person in
whose  name  this  Warrant  is   registered  as  the  holder  and  owner  hereof
(notwithstanding  any  notations of  ownership or writing  hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary, until presentation of this Warrant for registration or transfer
as provided in this Section 6.

     (b)  Exchange  and  Replacement.  This  Warrant  is  exchangeable  upon the
surrender hereof by the registered holder to the Company at its office described
in  Section  5, for new  Warrants  of like  tenor and date  representing  in the
aggregate  the right to  purchase  the  number  of  Warrant  Shares  that may be
purchased  hereunder,  each of such  new  Warrants  to  represent  the  right to
purchase such number of shares as shall be designated by said registered  holder
at the time of surrender. Subject to compliance with Section 6, this Warrant and
all rights  hereunder are transferable in whole or in part upon the books of the
Company  by the  registered  holder  hereof  in  person  or by  duly  authorized
attorney,  and a new Warrant shall be made and delivered by the Company,  of the
same  tenor  and  date  as  this  Warrant  but  registered  in the  name  of the
transferee, upon surrender of this Warrant, duly endorsed, to said office of the
Company.  Upon receipt by the Company of evidence reasonably  satisfactory to it
of the loss, theft,  destruction or mutilation of this Warrant,  and, in case of
loss, theft or destruction,  of indemnity or security reasonably satisfactory to
the Company,  and upon surrender and cancellation of this Warrant, if mutilated,
the Company  will make and deliver a new Warrant of like tenor,  in lieu of this
Warrant.  This  Warrant  shall be promptly  cancelled  by the  Company  upon the
surrender hereof in connection with any exchange,  transfer or replacement.  The
Company  shall pay all  expenses,  taxes (other than  transfer  taxes) and other
charges  payable in connection with the  preparation,  execution and delivery of
Warrants pursuant to this Section 6.

     Section 7. Transfer of Warrants or Warrant Shares.

     (a) Warrants and Warrant Shares Not Registered. The holder of this Warrant,
by accepting this Warrant, represents and acknowledges that this Warrant and the
Warrant  Shares  which may be  purchased  upon  exercise of this Warrant are not
being  registered  under the  Securities Act on the grounds that the issuance of
this Warrant and the  offering  and sale of such Warrant  Shares are exempt from
registration  under  the  Securities  Act  pursuant  to one or  more  exemptions
therefrom,  including Section 4(2) thereof,  and that the Company's  reliance on
such   exemption  is   predicated   in  part  on  the  initial   Warrantholder's
representations  and  agreements  made to and with the Company in the Securities
Purchase Agreement dated on or about the date hereof.

     Notwithstanding  any provisions  contained in this Warrant to the contrary,
this Warrant and the related  Warrant  Shares shall not be  transferable  except
upon the conditions  specified in this Section 7, which conditions are intended,
among other things,  to ensure  compliance with the provisions of the Securities
Act and  applicable  state  securities  laws in respect of the  transfer of this
Warrant or of such Warrant Shares.

     (b) Notice of Intention to Transfer; Opinion of Counsel. The holder of this
Warrant,  by accepting  this Warrant,  agrees that prior to any transfer of this
Warrant or any transfer of the related Warrant Shares, such holder will (i) give
written notice to the Company of its intention to effect such transfer, and (ii)
deliver to the  Company (A) an opinion of counsel for the Company or an opinion,
in form and substance  reasonably  satisfactory  to counsel for the Company,  of
counsel  skilled in securities  matters  (selected by such holder and reasonably
satisfactory  to the Company) as to the absence of the necessity of registration
under the Securities  Act, or (B) an  interpretative  letter from the Securities
and Exchange  Commission  to the effect that the  proposed  transfer may be made
without  registration  under the Securities  Act, in either case  accompanied by
evidence that such transfer will also be in  compliance  with  applicable  state
securities ("blue sky") laws;  provided,  however,  that the foregoing shall not
apply with  respect to any  Warrant  or  Warrant  Shares as to which  there is a
registration  statement  in effect under the  Securities  Act at the time of the
proposed transfer.

By accepting this Warrant, the Warrantholder agrees to indemnify the Company and
hold it harmless from and against all damages,  losses,  liabilities  (including
liability for rescission),  costs and expenses which the Company may incur under
the  Securities  Act or  otherwise  by  reason of any  misrepresentation  by the
Warrantholder  of facts  concerning it or any proposed  transfer of the Warrants
and/or  Warrant  Shares with respect to the  availability  of any exemption from
registration under the Securities Act.

     Section 8. Adjustment of Number of Shares and Purchase Price.

     (a)  Adjustments  for   Distributions,   Divisions  or   Consolidation   or
Combination of Shares. In the event of any increase or decrease in the number of
shares of issued Series A Preferred Stock by reason of a distribution,  division
or  consolidation or combination of such Shares at any time or from time to time
after the date hereof  such that the  holders of Series A Preferred  Stock shall
have had an adjustment made,  without payment therefor,  in the number of

                                     - 5 -
<PAGE>

shares of Series A Preferred Stock owned by them or, on or after any record date
fixed for the determination of eligible  holders,  shall have become entitled or
required  to have had an  adjustment  made in the  number of Series A  Preferred
Stock owned by them,  without payment  therefor,  there shall be a corresponding
adjustment  as to the number of shares of Series A  Preferred  Stock  covered by
this  Warrant  (and to the  Purchase  Price for each  Warrant  Share  under this
Warrant) with the result that the Warrantholder's  proportionate interest in the
shares of Series A Preferred  Stock shall be maintained as before the occurrence
of such event without  change in the aggregate  Purchase Price set forth in said
Warrant.

     (b) Adjustments for Recapitalization,  Reclassification,  Reorganization or
Other Like Capital  Transactions or for Merger and  Consolidation.  In the event
the Company (or any other  corporation  or other entity the  securities of which
are  receivable at the time upon exercise of the Warrant) shall effect a plan of
recapitalization,   reclassification,   reorganization  or  other  like  capital
transaction or shall merge or consolidate  with or into another entity or convey
all or  substantially  all of its assets to  another  entity at any time or from
time  to time  on or  after  the  date  hereof,  then  in  each  such  case  the
Warrantholder  upon  the  exercise  of  this  Warrant  at  any  time  after  the
consummation of such recapitalization, reclassification, reorganization or other
like capital transaction or of such merger, consolidation or conveyance shall be
entitled to receive (in lieu of the  securities or other  property to which such
holder  would  have  been  entitled  to  receive  upon  exercise  prior  to such
consummation), the securities or other property to which the Warrantholder would
have been entitled to have received upon consummation of the subject transaction
if the holder  hereof  had  exercised  this  Warrant  immediately  prior to such
consummation  without  adjustment to the aggregate  Purchase  Price set forth in
said  Warrant and all  subject to further  adjustment  pursuant to Section  8(a)
hereof.

     Section 9.  Elimination of Fractional  Interests.  The Company shall not be
required  to issue  certificates  representing  fractions  of shares of Series A
Preferred Stock upon exercise of this Warrant, nor shall it be required to issue
scrip or pay cash in lieu of  fractional  interests,  it being the intent of the
parties  that all  fractional  interests  shall be  eliminated  by rounding  any
fraction to the nearest  whole  number of shares of Series A Preferred  Stock or
other securities, properties or rights receivable upon exercise of this Warrant.

     Section 10. Special  Agreements of the Company.  The Company  covenants and
agrees that:

     (a) Reservation of Shares.  The Company will reserve and set apart and have
at all  times,  free  from  preemptive  rights,  a number  of shares of Series A
Preferred Stock deliverable upon the exercise of this Warrant,  and it will have
at all times any other rights or privileges  sufficient to enable it at any time
to fulfill all of its obligations hereunder.

     (b) Avoidance of Certain Actions. The Company will not, by amendment of its
Articles of Incorporation or Bylaws or through any  reorganization,  transfer of
assets,  consolidation,  merger, issue or sale of securities or otherwise, avoid
or take any action  which would have the effect of avoiding  the  observance  or
performance  of any of the terms to be observed or  performed  hereunder  by the
Company,  but will at all times in good faith  assist in

                                     - 6 -
<PAGE>

carrying  out all of the  provisions  of this  Warrant and in taking all of such
action as may be necessary or  appropriate in order to protect the rights of the
Warrantholder against impairment.

     (c) Successors. This Warrant shall be binding upon any corporation or other
entity  succeeding  to the Company by merger or  consolidation,  and the Company
will not enter into any such transaction without obtaining the written agreement
of any such successor to be bound by the terms of this Warrant as if it were the
issuer hereof.

     Section 11. Notifications by the Company. In case at any time:

          (a) the Company shall propose to make any  distribution to the holders
     of Series A Preferred Stock;

          (b) the Company shall make an offer for  subscription  pro rata to the
     holders of its Series A Preferred Stock of any additional securities of the
     Company;

          (c)  there  shall  be  any  reorganization,   merger,   consolidation,
     liquidation,  dissolution,  sale  of  assets,  equity  financing  or  other
     transaction  which would result in any  obligation of the Company to redeem
     outstanding  shares of Series A Preferred  Stock, or to make a distribution
     to holders of Series A Preferred Stock;

then, in any one or more of such cases, the Company shall give written notice to
Warrantholder  of the date on which (i) the books of the Company shall close, or
a record shall be taken for such  distribution or subscription  rights,  or (ii)
such reorganization,  merger, consolidation,  liquidation,  dissolution, sale of
assets,  equity financing or other transaction shall take place, as the case may
be. Such notice  shall also specify the date as of which the holders of Series A
Preferred Stock shall participate in such  distribution or subscription  rights,
or shall be entitled to exchange  their Series A Preferred  Stock for securities
or  other   property   deliverable   upon  any  such   reorganization,   merger,
consolidation,  liquidation,  dissolution,  sale of assets,  equity financing or
other  transaction,  as the case may be. Such written  notice shall be given not
less than 30 days and not more than 90 days prior to the action in question  and
not less than 30 days and not more than 90 days prior to the record  date or the
date on which the  Company's  transfer  books are closed in respect  thereto and
such notice may state that the record date is subject to the  effectiveness of a
registration  statement  under the Securities Act, or to a favorable vote of the
shareholders of the Company, if either is required.

     Section 12. Notices.  Any notice or other document required or permitted to
be  given or  delivered  to  Warrantholder  shall be  delivered  at,  or sent by
certified or registered mail to the Warrantholder at, the most recent address of
the Warrantholder  shown on the records of the Company, or to such other address
as shall have been  furnished  to the Company in writing by such  Warrantholder.
Any notice or other  document  required or permitted to be given or delivered to
the Company shall be sent by certified or registered  mail to the Company at its
address set forth in Section 4 (and notice shall be deemed  delivered  three (3)
business days after

deposit in the mail),  or such other address as shall have been furnished to the
Warrantholder by the Company.

     Section 13. No Voting Rights;  Limitation of Liability.  This Warrant shall
not entitle any  Warrantholder  to vote on any matter coming to the attention of
the  Shareholders of the Company or to any of the rights of a shareholder of the
Company.  No  provision  hereof,  in the  absence of  affirmative  action by the
Warrantholder  to  purchase  Series A  Preferred  Stock  hereunder,  and no mere
enumeration herein of the rights or privileges of the holder hereof,  shall give
rise to any  liability  of such holder for the  Purchase  Price or any rights of
such holder as a shareholder of the Company,  whether such liability is asserted
by the Company or by creditors of the Company.

     Section 14. Miscellaneous. This Warrant shall be governed by, and construed
and enforced in accordance with, the laws of the State of Missouri. This Warrant
and any provision hereof may be changed,  waived,  discharged or terminated only
by an instrument in writing signed by the party against which enforcement of the
same is sought.  The headings in this Warrant are for purposes of reference only
and shall not  affect  the  meaning  or  construction  of any of the  provisions
hereof.

terms and conditions:

     Interest.  The outstanding  principal  amount of this promissory note (this

in full, at the rate of 5.0% per annum.  All  computations  of interest shall be
made on the  basis  of a year of 365 (or  366,  as the case may be) days for the
actual  number of days  (including  the first day, but  excluding  the last day)
occurring in the period for which such interest is payable. No interest shall be

notice,  filing of suit and  diligence in  collecting  this Note,  and agrees to
remain bound for payment of this  obligation  notwithstanding  any  extension of
time,  substitution  or release of security or any other  indulgence  granted to

                               SECURITY AGREEMENT

From:    Connectria Corporation, a Missouri corporation ("Debtor"), whose chief
         executive office is located at 10845 Olive Boulevard, Suite 300, Creve
         Coeur, Missouri, 63141.

To:      MDSI Mobile Data Solutions Inc., a Canadian corporation (the "Secured
         Party").

(A)  Grant of Security Interest.

     In consideration  of financial  accommodations  given or continued,  Debtor
grants to the Secured Party a security  interest in the properties,  tangible or
intangible, described in the Property Schedule attached hereto as Exhibit A (the
"Collateral")  to secure payment and performance of all Debtor's  obligations to
the Secured Party,  whether currently existing or arising after the date hereof,
including, without limitation, the Debtor's obligations pursuant to the $250,000
Promissory  Note dated  June __,  2002,  made by Debtor in favor of the  Secured
Party (collectively, the "Indebtedness"). Unless otherwise defined herein, words
used in this  agreement  shall  have  the  meanings  given  them in the  Uniform
Commercial Code. An "Obligor" shall mean any person other than or in addition to
Debtor  who  now or  hereafter  is  indebted  or  obligated  on  sums  or  other
obligations secured hereby, including, without limitation, any guarantor.

(B)  Debtor's  Representations and Agreements.  Debtor warrants,  represents and
agrees:

     1.  Debtor  will  immediately  pay:  (a) any  Indebtedness  when due,  with
interest at the rate or rates provided for by any instrument or document  ("Loan
Document") evidencing the Indebtedness or from which the Indebtedness arises and
(b) the Secured  Party's  reasonable  costs of collecting the  Indebtedness  and
realizing on Collateral,  including  attorneys fees and expenses (whether or not
proceedings  are  instituted,  and  including  costs  relating to  bankruptcy or
insolvency  proceedings),  with interest from date of demand at the maximum rate
provided for by any Loan Document to which the Secured Party is a party.

     2. Debtor owns all Collateral  absolutely and no other person has or claims
any interest in any Collateral,  except for such interests of other persons that
exist as of the date of this  agreement or that arise in the ordinary  course of
business.  Debtor will defend any proceeding that may affect the Secured Party's
security  interest in any  Collateral,  and will indemnify the Secured Party for
all costs and  expenses  of the Secured  Party's  defense.  Notwithstanding  the
foregoing,  in connection with any financing  arrangement  entered into (and any
indebtedness  incurred by Debtor  thereunder,  including  future  advances made)
after the date  hereof with a  financial  institution,  Debtor may grant to such
financial  institution  a  security  interest  or  other  lien  on any or all of
Debtor's assets to secure such financing arrangement.

     3. Debtor will give the Secured Party 30 days' prior written  notice of any
change in Debtor's name, the location of any tangible Collateral or the Debtor's
jurisdiction of organization.

     4.  Debtor  will pay when due all  existing  or  future  charges,  liens or
encumbrances on and all taxes and assessments now or hereafter levied or imposed
on or affecting the Collateral.

     5. Debtor agrees that from time to time,  at the expense of Debtor,  Debtor
shall promptly  execute and deliver all further  instruments and documents,  and
take all further action,  that may be necessary or desirable in order to perfect
and protect any security  interest granted hereby or to enable the Secured Party
to exercise and enforce their rights and remedies  hereunder with respect to any
Collateral.  Debtor  hereby  authorizes  the  Secured  Party to file one or more
financing or continuation statements, and amendments thereto, relative to all or
any part of the  Collateral  without the signature of Debtor where  permitted by
law. A carbon,  photographic  or other  reproduction  of this  agreement  or any
financing  statement  covering  the  Collateral  or any  part  thereof  shall be
sufficient as a financing  statement where permitted by law. Debtor will provide
the Secured Party such information regarding the nature,  extent,  condition and
location of the Collateral as the Secured Party may request from time to time.

     6. The Secured Party is irrevocably appointed Debtor's  attorney-in-fact to
do any act which  Debtor is  obligated  hereby to do and fails to do within  ten
(10) days after demand  therefor,  and to execute and file in Debtor's  name any
financing  statements  and  amendments or other  filings,  notices and documents
thereto  required to protect

                                     - 1 -
<PAGE>

or perfect the Secured Party's security interest  hereunder,  all to protect and
preserve the Collateral and the Secured Party's rights hereunder. While an Event
of Default has occurred and is  continuing,  the Secured Party may: (a) endorse,
collect  and  receive   delivery  or  payment  of   instruments   and  documents
constituting  Collateral;  (b) make  extension  agreements  with  respect  to or
affecting Collateral,  exchange it for other Collateral,  release persons liable
thereon or take security for the payment  thereof,  and  compromise  disputes in
connection  therewith;  (c)  use  or  operate  Collateral  for  the  purpose  of
preserving Collateral or its value and for preserving or liquidating Collateral;
(d)  demand,  sue for,  collect,  receive and give  acquittance  for any and all
monies  due or to become  due  thereon  or by virtue  thereof;  and (e)  settle,
compromise,  compound,  prosecute or defend an action or proceeding with respect
thereto.

     7. The Debtor  waives (a) any right to require the Secured Party to proceed
against  any  Obligor  before the  Debtor,  or to pursue any other  remedy;  (b)
presentment,  protest  and  notice  of  protest;  (c) any  right to  direct  the
application  proceeds of the Secured  Party's  realization  on any Collateral to
particular  Indebtedness;  and (d) any right of subrogation to the Secured Party
until Indebtedness shall have been paid or performed in full.

(C)  Defaults and Remedies; Non-waiver.

     1. Each of the  following  shall  constitute  an "Event  of  Default:"  (a)
Debtor's failure to pay any sum secured hereby when the same is due; (b) failure
to  perform  or  comply  with any  agreement,  condition  or  provision  in this
agreement  or any Loan  Document  within 30 days after  written  notice from the
Secured Party  indicating that a failure to perform will constitute an "Event of
Default" hereunder;  (c) any warranty contained in this agreement shall prove to
have been  materially  inaccurate  when made;  or (d) the filing of any petition
under  bankruptcy or similar  debtors' relief laws by the Debtor or any Obligor,
the passage of 60 days after the filing of any such petition by another  against
the Debtor or any Obligor without the relevant  proceeding  being  discharged or
stayed,  or any  assignment  for the benefit of  creditors or  appointment  of a
receiver involving substantially all of the Debtor's assets.

     2. During the continuance of an Event of Default, the Secured Party may, by
notice to the  Debtor,  declare  that  they are  realizing  upon the  Collateral
hereunder.  Upon such notice, so long as an Event of Default is continuing:  (a)
the Secured  Party may declare all or any part of the  Indebtedness  owed to the
Secured  Party to be  immediately  due and (b) the Secured  Party shall have all
rights  provided by this  agreement  or provided by law,  including  the Uniform
Commercial  Code, and may sell Collateral in one or more sales,  and such rights
shall be exercised as determined by the Secured Party.  (The preceding  sentence
shall not limit the rights and  remedies  of the Secured  Party  pursuant to the
Loan Documents with respect to its Indebtedness.) Upon the occurrence and during
the  continuance  of an Event of Default,  the proceeds of any sale of, or other
realization  upon,  all or any part of the Collateral and any cash held shall be
applied by the Secured Party in the following order of priorities: (i) first, to
payment of the expenses of such sale or other realization,  including reasonable
compensation  to agents and  counsel for the Secured  Party,  and all  expenses,
liabilities  and advances  incurred or made by the Secured  Party in  connection
therewith;  (ii) second, to the payment of all indebtedness of any other secured
parties with respect to security  interests  (A) granted  prior to the effective
date of this Security Agreement for indebtedness incurred prior to the effective
date of this Security Agreement, or (B) granted pursuant to Section (B)2 of this
Security  Agreement,  until all such indebtedness of such parties have been paid
in full; (iii) third, to the payment of all Indebtedness to the Secured Party or
its respective  successors and assigns,  until all  Indebtedness  of the Secured
Party  shall  have been paid in full;  (v)  fourth,  to the  payment  of amounts
required by law; and (iv) finally, to payment to the Debtor or its successors or
assigns, or as a court of competent jurisdiction may direct, of any surplus then
remaining from such proceeds.  At the Secured Party's option,  any such sale may
be conducted in any locality where the Secured Party has an office.  The Secured
Party may  purchase  at such  sale.  The  Secured  Party may  require  Debtor to
assemble the  Collateral  and make it available to the Secured  Party at a place
designated by the Secured  Party that is reasonably  convenient to both parties.
The Secured Party's  acceptance of partial or delinquent  payments or failure of
the Secured  Party to  exercise  any right or remedy at any time shall not waive
any  obligation of any Debtor or Obligor,  or any right or remedy of the Secured
Party, or modify this agreement, or waive any other similar default.

(D)  Expenses.

     In the event that the Debtor  fails to comply  with the  provisions  of the
Loan Documents or this Security Agreement, such that the validity, perfection or
rank of any security interest is thereby  diminished or put at risk, the Secured
Party (i) may  deliver  written  notice  of such  non-compliance  to the  Debtor
requesting  that it cure such  non-compliance,  and (ii) if within ten  business
days  after  delivery  of such  notice  the  Debtor  has  failed  to  cure  such
non-compliance, the Secured Party may, but shall not be required to, effect such
compliance on behalf of the Debtor,  and the Debtor shall  reimburse the Secured
Party for the reasonable costs thereof on demand. All insurance expenses and all
expenses of protecting,  storing, warehousing,  appraising,  insuring, handling,
maintaining and shipping the Collateral,  any and all excise,  property,  sales,
and use taxes imposed by any state,  federal,  or local  authority on any of the
Collateral,  or in  respect  of  periodic  appraisals  and  inspections  of  the
Collateral  to the extent the same may  reasonably  be  requested by the Secured
Party from time to time, or in respect of the sale or other disposition thereof,
shall be borne and paid by the Debtor;  and if the Debtor  fails to promptly pay
any portion thereof when due, the Secured Party may, at their option,  but shall
not be required to, pay the same and charge the Debtor's account  therefor,  and
the Debtor  agrees to  reimburse  the  Secured  Party  therefor  on demand.  All
reasonable  sums  so  paid  or  incurred  by the  Secured  Party  for any of the
foregoing  and any and all other sums for which the  Debtor  may  become  liable
hereunder and all costs and expenses (including  attorneys' fees, legal expenses
and court  costs)  reasonably  incurred by the  Secured  Party in  enforcing  or
protecting the security  interests or any of their rights or remedies under this
Security Agreement,  shall, together with interest thereon for each day from the
date demanded until paid at the rate of 8% per annum, be obligations  secured by
this Security Agreement.

(E)  Subordination.

     Secured Party hereby agrees that in connection with Debtor's  entering into
any credit  facility or finance  arrangement  with a financial  institution  for
purposes of obtaining  working  capital and other general  corporate  financing,
Secured  Party  shall  execute  and  deliver  to such  financial  institution  a
subordination agreement subordinating in favor of such financial institution its
rights to payment of any  indebtedness  owed by Debtor to Secured  Party and all
security interests which Debtor has then granted to Secured Party. Secured Party
further agrees to execute and deliver to such financial  institution  such other
documents  as such  financial  institution  may  reasonably  request in order to
implement such subordination agreement.

(F)  General Provisions.

     1. On transfer of all or any part of the Indebtedness,  as permitted by the
Loan  Document,  Secured  Party  may  transfer  all or any part of the  Security
Interest securing such Indebtedness. This agreement benefits the Secured Party's
successors and assigns and binds Debtor's successors and assigns. Time is of the
essence.  This agreement and  supplementary  schedules hereto contain the entire
security agreement between the Secured Party and Debtor. Debtor will execute any
additional  agreements,   assignments  or  documents  which  the  Secured  Party
reasonably  may reasonably  request to effectuate  this agreement or perfect any
rights or interests of Secured Party hereunder. This agreement shall be governed
by, and construed in accordance with, the laws of the State of Washington.

     2. Beyond the  exercise of  reasonable  care in the  custody  thereof,  the
Secured  Party  shall have no duty as to any  Collateral  in its  possession  or
control  or in the  possession  or  control of any agent or bailee or any income
thereon or as to the  preservation  of rights against prior parties or any other
rights pertaining  thereto.  The Secured Party shall be deemed to have exercised
reasonable  care in the  custody  of the  Collateral  in its  possession  if the
Collateral is accorded  treatment  substantially  equal to that which it accords
its own property,  and shall not be liable or responsible for any loss or damage
to any of the Collateral,  or for any diminution in the value thereof, by reason
of the  act  or  omission  of  any  warehouseman,  carrier,  forwarding  agency,
consignee or other agent or bailee  selected by the Secured Party in good faith;
provided,  however,  nothing in this Section  shall be deemed to  prejudice  any
rights of the Debtor  against such  warehouseman,  carrier,  forwarding  agency,
consignee or other agent or bailee.

     3. Neither this Security Agreement nor any provision hereof may be changed,
waived,  discharged  or  terminated  orally,  but only in writing  signed by the
Debtor and the Secured Party.

                                     - 3 -
<PAGE>

     4. All notices, approvals, requests, demands and other communications shall
be given in accordance with the Loan Documents.

     5. Upon the repayment in full of the Indebtedness,  this Security Agreement
shall terminate and all rights to the Collateral shall revert to the Debtor.

     6. Captions, titles and section and paragraph divisions and arrangements in
this agreement and in any instruments and documents heretofore or hereafter made
or executed are for convenience and for reference only, and shall not affect the
meaning,  interpretation  or  construction  thereof.  Whenever  the  context  so
requires,  any gender shall include all other genders,  and the singular  number
shall include the plural.

ORAL AGREEMENTS OR ORAL COMMITMENTS TO LOAN MONEY,  EXTEND CREDIT, OR TO FORBEAR
FROM ENFORCING REPAYMENT OF A DEBT ARE NOT ENFORCEABLE UNDER WASHINGTON LAW.

                            NONCOMPETITION AGREEMENT

     This  Noncompetition  Agreement (this  "Agreement"),  is entered into as of
this ____ day of June, 2002 among Richard S. Waidmann ("Mr. Waidmann"),  Eric Y.
Miller ("Mr.  Miller"),  Connectria  Corporation,  a Missouri  corporation,  its
affiliates,  successors  and  assigns  ("Connectria"),   and  MDSI  Mobile  Data
Solutions Inc., a Canadian corporation, its affiliates,  successors, and assigns
("MDSI").  Mr. Waidmann and Mr. Miller are sometimes collectively referred to as
the  "Executives."  Mr.  Waidmann,  Mr.  Miller,  and  Connectria  are sometimes
referred to collectively as the "Covenantors."

                                 R E C I T A L S

     A.   Pursuant to an Agreement and Plan of  Reorganization,  dated as of May
9, 2000 (the "Reorganization  Agreement"),  MDSI acquired all of the outstanding
voting  securities  of  Connectria  by a merger of a subsidiary of MDSI with and
into Connectria as the surviving corporation (the "Merger"), and the Executives,
who  collectively  owned 97.6% of the  outstanding  common  stock of  Connectria
immediately  prior to the Merger,  received an  aggregate  of 824,700  shares of
common stock of MDSI as the consideration for the Merger (the "MDSI Shares").

     B.   Since  the  closing  of the  Merger,  the  Executives  have  served as
employees and executive  officers of MDSI and Mr. Waidmann has served a director
of MDSI.  In such  capacities,  the  Executives  have had  access to and  gained
knowledge of certain confidential  information of MDSI and specialized knowledge
of its business.

     C.   MDSI and the Executives have reached a mutual understanding concerning
the unwinding of MDSI's acquisition of Connectria,  as set forth in the Exchange
Agreement  among MDSI,  Connectria and the Executives  dated as of June __, 2002
(the  "Exchange  Agreement"),  to which this Agreement is attached as Exhibit F.
The  execution  and  delivery  of this  Agreement  by the  parties  hereto  is a
condition to the closing of the transactions described in the Exchange Agreement
and the receipt by the Executives and Connectria of the  consideration  provided
for therein.

     NOW,  THEREFORE,  in consideration of the foregoing mutual premises and the
following representations, warranties, covenants and agreements set forth herein
and in the Exchange  Agreement,  and for other good and valuable  consideration,
the receipt and  sufficiency of which are hereby  acknowledged,  the Covenantors
and MDSI, intending to be legally bound hereby, agree as follows:

                                A G R E E M E N T

     1.   ACKNOWLEDGEMENTS.  The parties represent,  warrant,  acknowledge,  and
agree that:

          a.   Business.  MDSI's business  consists of, among other things,  the
business   described  in  MDSI's   filings  with  the  Securities  and  Exchange
Commission,  including,

                                       1
<PAGE>

but not  limited  to, its Annual  Report on Form 10-K for the fiscal  year ended
December 31, 2001 (the "Business");

          b.   Specialized  Knowledge.  As a result of the  Covenantors'  active
participation in MDSI and the Business,  they have specialized  knowledge of the
Business,  including, but not limited to, the market in which MDSI operates, the
method by which MDSI earns revenue, key personnel of MDSI, key customer contacts
and prospects,  and other Confidential Information (defined below) ("Specialized
Knowledge");

          c.   Irreparable  Harm. MDSI would be irreparably  harmed and impaired
if the Covenantors  were to engage,  directly or indirectly,  in any Competitive
Services  (defined below) or disclose any Specialized  Knowledge in violation of
this Agreement.

          d.   Reasonable Covenants.  The Covenantors have been fully advised by
counsel in connection with the negotiation,  preparation, execution and delivery
of this Agreement, the Exchange Agreement, and the transactions  contemplated by
those agreements. The Covenantors agree that MDSI would not engage in any of the
transactions  contemplated by the Exchange  Agreement and this Agreement without
the  benefit  of each of the  restrictive  covenants  and  agreements  contained
herein.  Accordingly,  the Covenantors  agree to be bound by the  noncompetition
agreement and the other restrictive  covenants and agreements  contained in this
Agreement to the maximum extent permitted by law, it being the intent and spirit
of the  parties  that the  noncompetition  agreement  and the other  restrictive
covenants and agreements  contained herein shall be valid and enforceable in all
respects.

     2.   RESTRICTIVE COVENANTS.

          a.   Confidential Information.

               (i)  MDSI Information. The Covenantors agree to hold in strictest
confidence and not to use or disclose to any person, firm,  corporation or other
entity,  any  Confidential  Information of MDSI. If at any time the  Covenantors
become  involved  in a legal  proceeding  that may result in  disclosure  of any
Confidential  Information,  the  Covenantors  will promptly  notify MDSI of such
proceeding  prior to disclosing  any  Confidential  Information,  and will fully
cooperate  with MDSI in whatever  actions it deems are  necessary to protect the
Confidential Information.

               (ii) Third Party Information. The Covenantors recognize that MDSI
has received  confidential  information  from third parties subject to a duty on
MDSI's part to maintain the  confidentiality  of such  information and to use it
only  for  certain  limited  purposes.  The  Covenantors  agree to hold all such
confidential or proprietary  information in the strictest  confidence and not to
disclose it to any person, firm or corporation.

          b.   Non-Competition.  The  Covenantors  agree  that  until the second
anniversary  of the Closing  Date,  as defined in the  Exchange  Agreement  (the
"Closing Date"), the Covenantors will not as individuals, proprietors, partners,
stockholders,  officers,  employees,  directors,  consultants,  joint venturers,
investors,  lenders, or in any other capacity whatsoever, engage anywhere in the
world in any  Competitive  Services  (defined  below);  provided,  however,  the
Covenantors  may own,  directly or indirectly,  solely as a passive  investment,
securities of any

                                       2
<PAGE>

entity traded on any national  securities exchange or automated quotation system
if none of the Covenantors  are a controlling  person of, or a member of a group
which controls such entity,  and the Covenantors are not collectively,  directly
or indirectly,  the beneficial owners of one percent (1.0%) or more of any class
of  securities  of such  entity  (as  determined  pursuant  to Rule 13d-3 of the
Securities Exchange Act of 1934, as amended, provided, however, that in the case
of  rights  to  acquire  securities,  a  Covenantor  shall be  deemed  to be the
beneficial  owner of such  securities  without  regard to whether the rights are
exercisable   within   the  sixty   (60)  day   period   referred   to  in  Rule
13d-3(d)(1)(i)).

          c.   Solicitation of Employees, Consultants and Other Parties.

               (i)  Customers and Suppliers.  The  Covenantors  agree that until
the second  anniversary of the Closing Date, the Covenantors  shall not directly
or indirectly solicit, influence, induce, recruit or encourage (collectively, to
"Solicit") or attempt to Solicit any licensor, licensee, customer or supplier of
the MDSI or its products,  which the Covenantors or any employee,  consultant or
agent of Connectria had contact with while employed by or affiliated  with MDSI,
or that are  known to any such  persons,  in  order to  divert  his,  her or its
business away from MDSI or otherwise terminate his, her or its relationship with
MDSI.

               (ii) Employees.  The Covenantors  acknowledge and agree that they
possess  confidential  information  about  employees  of MDSI  relating to their
education,  experience, skills, abilities,  compensation and benefits, and their
interpersonal relationships with customers or suppliers of MDSI. The Covenantors
acknowledge and agree that the information  they possess about MDSI employees is
not generally known, is of substantial  value to MDSI in developing its business
and in securing and  retaining  customers,  and was acquired by the  Covenantors
because of their business position with MDSI. Accordingly, the Covenantors agree
that until the second  anniversary of the Closing Date, they will not,  directly
or indirectly, Solicit any employee or consultant of MDSI for the purpose of (i)
being employed by Connectria or by any person or entity engaged in the Business,
or (ii) interfering with or terminating his or her employment  relationship with
MDSI for any purpose or no purpose; and that the Covenantors will not convey any
such confidential  information or trade secrets about other employees of MDSI to
any other person or entity.

          d.   Returning MDSI Documents.  The Covenantors  represent and warrant
that,  except as otherwise  provided in the Exchange  Agreement or an Exhibit or
Schedule  thereto,  they have  delivered  or will  deliver to MDSI (and will not
keep,  recreate or deliver to anyone else) any and all devices,  records,  data,
notes, reports,  proposals,  lists,  correspondence,  specifications,  drawings,
blueprints,  sketches, laboratory notebooks,  materials, flow charts, equipment,
other tangible media or property,  or reproductions of any aforementioned  items
developed or otherwise  acquired by  Covenantors  for MDSI while  employed by or
affiliated with MDSI, or otherwise belonging to MDSI.

     3.   RIGHTS AND REMEDIES UPON BREACH BY THE  EXECUTIVES OR THE MDSI. If the
Covenantors  breach or threaten to commit a breach of any of the  provisions  of
this Agreement MDSI shall have the following rights and remedies,  each of which
shall be independent of the others and severally enforceable,  and each of which
shall be in  addition  to,  and not in lieu of,  any other  rights  or  remedies
available to MDSI:

                                       3
<PAGE>

          a.   Specific Performance. The right and remedy to have each and every
one of the covenants in this Agreement  specifically  enforced and the right and
remedy to obtain injunctive relief,  including a temporary restraining order and
a  preliminary  or  temporary  injunction,  it being  agreed  that any breach or
threatened breach of any of the  noncompetition  or other restrictive  covenants
and agreements  contained herein would cause irreparable injury to MDSI and that
money damages would not provide an adequate remedy at law to MDSI.

          b.   Accounting.  The right and remedy to require the  Covenantors  to
account for and pay over to MDSI all compensation,  profits,  monies,  accruals,
increments  or other  benefits  derived or  received by the  Covenantors  or any
Connected  Entity  (defined  below) that result from any transaction or activity
constituting a breach of this Agreement.

          c.   Severability of Covenants.  The Covenantors acknowledge and agree
that the noncompetition and other restrictive covenants and agreements contained
herein are  reasonable  and valid in  geographic  and temporal  scope and in all
other respects, and do not impose limitations greater than that are necessary to
protect the goodwill,  Confidential Information, and other business interests of
MDSI. If, however, any court subsequently  determines that any of such covenants
or agreements,  or any part thereof, is invalid or unenforceable,  the remainder
of such  covenants  and  agreements  shall not thereby be affected  and shall be
given full effect without regard to the invalid portions.

          d.   Blue-Penciling. If any court of competent jurisdiction determines
that any of the noncompetition  and other restrictive  covenants and agreements,
or any part  thereof,  is  unenforceable  because of the duration or  geographic
scope of such provision,  such court shall have the power to reduce the duration
or scope of such  provision,  as the case may be, and, in its reduced form, such
provision  shall  then  be  enforceable  to  the  maximum  extent  permitted  by
applicable law.

          e.   Enforceability in All Jurisdictions. The parties hereto intend to
and hereby  confer  jurisdiction  to enforce each and every one of the covenants
and agreements  contained herein upon the courts of any jurisdiction  within the
geographic  scope of such covenants and agreements.  If the courts of any one or
more of such jurisdictions hold any such covenant or agreement  unenforceable by
reason of the breadth or such scope or  otherwise,  it is the  intention  of the
parties hereto that such determination shall not bar or in any way affect MDSI's
right to the  relief  provided  above in the  courts of any  other  jurisdiction
within the geographic scope of such covenants and agreements,  as to breaches of
such  covenants and  agreements  in such other  respective  jurisdictions,  such
covenants and  agreements as they relate to each  jurisdiction  being,  for this
purpose, severable into diverse and independent covenants and agreements.

                               EXCHANGE AGREEMENT

     THIS AMENDMENT NO. 1 TO THE EXCHANGE  AGREEMENT  ("Amendment")  is made and
entered  into as of the 30th of June,  2002,  by and among (i) MDSI  Mobile Data
Solutions  Inc.,  a Canadian  corporation  ("MDSI");  (ii)  Richard S.  Waidmann
("Waidmann") and Eric Y. Miller ("Miller," and collectively  with Waidmann,  the
"Shareholders"),  residents  of the  State of  Missouri;  and  (iii)  Connectria
Corporation, a Missouri corporation ("Connectria").

                                    RECITALS

     A.   Pursuant to an Agreement and Plan of  Reorganization,  dated as of May
9, 2000 (the "Reorganization  Agreement"),  MDSI acquired all of the outstanding
voting  securities  of  Connectria  by a merger of a subsidiary of MDSI with and
into Connectria as the surviving  corporation (the "Merger") in a reorganization
pursuant to Section 368(a) of the Internal Revenue Code of 1986, as amended (the
"Code").

     B.   In order to unwind the Reorganization  Agreement, and the transactions
contemplated  thereby,  MDSI,  Connectria and the  Shareholders  entered into an
Exchange Agreement dated as of June 26, 2002 ("Exchange Agreement").

     C.   The parties wish to amend the  Exchange  Agreement as provided in this
Amendment.

     In  consideration  of the foregoing and the mutual covenants and agreements
contained  herein and in the  Exchange  Agreement,  the parties  hereto agree as
follows:

          1.   Capitalized Terms. Except as otherwise defined in this Amendment,
capitalized  terms used herein shall have the meanings  ascribed  thereto in the
Exchange Agreement.

          2.   Section 1. Section 1 of the Exchange  Agreement is hereby deleted
in its entirety and replaced with the following:

               1.   Amendment  of  Connectria's  Articles of  Incorporation  and
     Bylaws.  Prior to Closing (as defined in Section 5 below),  MDSI shall take
     all   appropriate   action  to  cause   Article  III  of  the  Articles  of
     Incorporation  of Connectria to be amended (i) to authorize the issuance of
     up to one hundred  thousand  (100,000) shares of preferred stock, par value
     .01 per share (the "Preferred  Stock"),  and (ii) to authorize the Board of
     Directors of Connectria, by resolution or resolutions, at any time and from
     time to time, to divide and establish any or all of the unissued  shares of
     Preferred  Stock  into  one  or  more  series  and,  without  limiting  the
     generality of the foregoing,  to fix and determine the  designation of each
     such share,  the number of shares  which shall  constitute  such series and
     certain powers,  preferences and relative participating,  optional or other
     special rights and  qualifications,  limitations  and  restrictions  of the
     shares  of  each  series  so  established  (such  amendment,  the  "Charter
     Amendment").  In  addition,  the parties  hereto  shall cause the bylaws of
     Connectria  to  be  amended  to  include  a  new  Article  XIII  containing
     restrictions on the transferability of shares of stock of Connectria,  such
     Article to be in form and substance  mutually  satisfactory  to the parties
     hereto.

          3.   Section 3. Section 3 of the Exchange  Agreement is hereby deleted
in its entirety and replaced with the following:

               3.   Capital Contributions and Warrant. Immediately following the
