2.   Purchase and Sale of Target Shares.

     (a)  Basic Transaction.  On and subject to the terms and conditions of this
Agreement, the Buyer agrees:

          (i)       to  purchase  from  each  of the  Sellers,  and  each of the
                    Sellers agrees to sell to the Buyer, all of his, hers or its
                    Target  Shares for the  consideration  specified  in Section
                    2(b) below;

          (ii)      to purchase all, but not less than all, of the Target Shares
                    owned by  Shareholders  (other than the  Sellers) at Closing
                    for the Shareholders consideration specified in Section 2(b)
                    below; and




                                      -6-
<PAGE>

          (iii)     to ensure that certain  holders of unvested  Target  Options
                    will receive Buyer Options having the  attributes  described
                    in Section 2(e) below.

     (b)  Purchase   Price.   The  purchase  price  for  the  Target  Shares  is
US$20,000,000 (the "Purchase Price").  Subject to the balance of this Article 2,
the Buyer shall pay the  Purchase  Price to the  Shareholders  at the Closing by
delivery of a certain number of Buyer Shares (the "Closing  Shares")  determined
by dividing US$20,000,000 by the weighted average of the closing price per share
of Buyer  Shares as  reported  by the  Nasdaq  National  Market for the ten (10)
consecutive  trading day period  ending two business days prior to the Effective
Date;  provided that, if such weighted average price per share as so calculated,
is greater than  US$66.67  per share,  such price shall be deemed to be US$66.67
per share,  and if such weighted  average price per share, as so calculated,  is
less than  US$36.36  per share,  such price shall be deemed to be  US$36.36  per
share (the  weighted  average  price per share as  determined  pursuant  to this
sentence being referred to herein as the "Closing Value").  For the avoidance of
doubt,  "weighted  average" is calculated by multiplying the daily closing price
by the daily trading volume for each relevant day and dividing the total of such
sums by the total trading volume over the ten-day period. The Buyer shall not be
required to issue fractional  shares of Buyer Shares,  including as Buyer Shares
are  released  to the  Sellers  under the Escrow  Agreement,  and any  resulting
fractional shares shall be ignored.

     (c)  Exercise of Warrants and Options. The Sellers shall exercise and shall
use their commercially reasonable efforts to cause all other holders to exercise
all Target Warrants and vested Target Options.

     (d)  Allocation of Purchase  Price Among  Shareholders.  The Closing Shares
shall  be  allocated  among  the  Shareholders  as set  out in  the  Schedule  2
Allocation  Schedule.  The  parties  acknowledge  and agree that the  Allocation
Schedule  has  been  crystalized  and  fixed  as of May 16,  2000  and  that the
calculation of whether options have vested and the  determination of the accrual
by the Shareholders of all rights to dividends and liquidation preferences cease
and are determined as of that date.

     (e)  Treatment of Unvested Target  Options.  The parties agree to amend the
terms and  conditions  of all of the Target  Options that are unvested as at the
Closing, to the effect that such unvested Target Options:

          (i)       will  constitute  options  to  acquire  Buyer  Shares  at  a
                    conversion  ratio of 13  Target  Options  for  every 1 Buyer
                    Option;

          (ii)      will have an exercise  price equal to the exercise  price of
                    the underlying Target Options multiplied by 13;

          (iii)     will vest in  accordance  with the  vesting  schedule of the
                    underlying Target Options; and

          (iv)      in all other respects,  will continue to be issued under the
                    Option Plan and which  Option Plan will be amended  prior to
                    Closing to have terms and conditions  substantially  similar
                    to those  contained  in the  Pivotal

their  respective  Proportional  Shares  shall be held in escrow (the  "Escrowed
Shares")  under  the terms of the  Escrow  Agreement  until  one year  after the
Closing Date (or if an indemnity claim by the Buyer remains  unsatisfied on such
one year  anniversary  date,  then until such claim is satisfied).  All Escrowed
Shares  shall be valued at the Closing  Value for  purposes of  determining  the
extent to which an indemnity obligation is satisfied, irrespective of the market
price of the Escrowed Shares at the time of the indemnity payment. To the extent
there are Escrowed Shares available, they shall be released back to the Buyer in
satisfaction (or partial  satisfaction)  of any indemnity  payment under Article
8(b)  below,  as more  particularly  set  forth  in and  subject  to the  Escrow
Agreement.

Agreement  (the  "Closing")  shall  take place at the  offices of Borden  Ladner
Gervais in Vancouver,  British  Columbia,  commencing at 9:00 a.m. local time on

to the  obligations of the Parties to consummate the  transactions  contemplated
hereby (other than  conditions  with respect to actions the  respective  Parties
will take at the Closing itself) or such other date as the Buyer and the Sellers
may mutually determine (the "Closing Date").

6.   Post-Closing Covenants.

     The  Parties  agree as follows  with  respect to the period  following  the
Closing.

     (a)  General.  In case at any time after the Closing any further  action is
necessary to carry out the purposes of this Agreement,  each of the Parties will
take such further  action  (including the execution and delivery of such further
instruments and documents) as any other Party reasonably may request, all at the
sole cost and expense of the requesting  Party (unless the  requesting  Party is
entitled  to  indemnification  therefor  under  Section  8 below).  The  Sellers
acknowledge and agree that from and after the Closing the Buyer will be entitled
to  possession  of  all  documents,  books,  records  (including  Tax  records),
agreements,  and  financial  data of any sort  belonging  to the  Target and its
Subsidiaries.

     (b)  Litigation Support. In the event and for so long as any Party actively
is  contesting  or  defending  against any action,  suit,  proceeding,  hearing,
investigation,  charge,  complaint,  claim, or demand in connection with (i) any
transaction  contemplated  under  this  Agreement  or (ii) any fact,  situation,
circumstance,  status, condition,  activity, practice, plan, occurrence,  event,
incident, action, failure to act, or transaction on or prior to the Closing Date
involving any of the Target and its Subsidiaries, each of the other Parties will
cooperate with him or it and his or its counsel in the contest or defense,  make
available their personnel,  and provide such testimony and access to their books
and records as shall be necessary in connection with the contest or defense, all
at the sole cost and expense of the  contesting  or defending  Party (unless the
contesting  or defending  Party is entitled to  indemnification  therefor  under
Section 8 below).

     (c)  Transition.  None of the Sellers will take any action that is designed
or intended to have the effect of discouraging any lessor,  licensor,  customer,
licenses,  supplier,  or other  business  associate of any of the Target and its
Subsidiaries  from maintaining the same business  relationships  with the Target
and its Subsidiaries  after the Closing as it maintained with the Target and its
Subsidiaries  prior to the Closing.  Each of the Sellers will refer all customer
inquiries  relating to the businesses of the Target and its  Subsidiaries to the
Buyer from and after the Closing.

     (d)  Confidentiality.  Each of the Sellers  will treat and hold as such all
of the  Confidential  Information,  refrain  from using any of the  Confidential
Information  except in connection with this Agreement,  and deliver  promptly to
the Buyer or  destroy,  at the  request  and option of the Buyer,  all  tangible
embodiments (and all copies) of the Confidential Information which are in his or
its possession and that belong to the Target or its  Subsidiaries.  In the event
that any of the Sellers is requested  or required  (by oral  question or request
for information or documents in any legal proceeding,  interrogatory,  subpoena,
civil  investigative  demand,  or similar  process) to disclose any Confidential
Information,  that  Seller  will  notify the Buyer  promptly  of the  request or
requirement so that the Buyer may seek an appropriate  protective order or waive
compliance  with the  provisions of this Section  6(d).  If, in the absence of a
protective order or the receipt of a waiver hereunder, any of the Sellers is, on
the advice of counsel, compelled to disclose any Confidential Information to any
tribunal  or else stand  liable for  contempt,  that  Seller  may  disclose  the
Confidential Information to the tribunal; provided, however, that the disclosing
Seller  shall use his or its  reasonable  efforts to obtain,  at the  reasonable
request of the Buyer,  an order or other assurance that  confidential  treatment
will be




                                      -31-
<PAGE>

accorded  to  such  portion  of  the  Confidential  Information  required  to be
disclosed as the Buyer shall designate.

     (e)  Covenant Not to Compete.  For a period from and after the Closing Date
and  expiring  one year after the later of the Closing Date and the last date of
employment  of Seller  with Buyer (if such  Seller  becomes an employee of Buyer
upon Closing),  none of the Employee  Sellers will engage directly or indirectly
in  any  business  anywhere  in  the  world  that  any of  the  Target  and  its
Subsidiaries  conducts  or has made plans to engage in as of the  Closing  Date;
provided, however, that no owner of less than 1% of the outstanding stock of any
publicly-traded  corporation  shall be deemed to engage solely by reason thereof
in any of its businesses.  If an arbitrator  declares that any term or provision
of this Section  6(e) is invalid or  unenforceable,  the Parties  agree that the
arbitrator  shall have the power to reduce the scope,  duration,  or area of the
term or  provision,  to delete  specific  words or  phrases,  or to replace  any
invalid or  unenforceable  term or provision  with a term or  provision  that is
valid and  enforceable and that comes closest to expressing the intention of the

                    of the  Sellers  agrees to  severally  indemnify  the Seller
                    Indemnified Parties, from and against its Proportional Share
                    of any  Adverse  Consequences  they may suffer  through  and
                    after the date of the claim for  indemnification  (including
                    any Adverse  Consequences the Seller Indemnified Parties may
                    suffer  after  the end of any  applicable  survival  period)
                    resulting  from,  arising out of, relating to, in the nature
                    of,   or   caused   by  the   breach   provided   that  such
                    indemnification  shall  not  exceed  a  cumulative  total of
                    US$2,000,000  (the "General Cap") in respect of all Sellers;
                    provided further,  however,  that the Sellers shall not have
                    any  obligation  to indemnify the Buyer from and against any
                    Adverse   Consequences   resulting  from,  arising  out  of,
                    relating  to, in the  nature  of, or caused by the breach of
                    any  representation,  warranty  or  covenant  of the Sellers
                    contained   in  this   Agreement   above  until  the  Seller
                    Indemnified  Parties  have  collectively   suffered  Adverse
                    Consequences  by reason of all such  breaches in excess of a
                    US$100,000  aggregate  threshold (at which point the Sellers
                    will be obligated  to

                    Consequences relating back to the first dollar).

          (ii)      In the event:  (A) any of the Sellers  breaches any of their
                    representations,  warranties,  and  covenants  contained  in
                    Sections 4(m), 4(u), 4(v) and 4(aa) above,  and, if there is
                    an  applicable  survival  period  pursuant  to Section  8(a)
                    above,  provided  that the Buyer  makes a written  claim for
                    indemnification  against  any of  the  Sellers  pursuant  to
                    Section  11(h) below  within such  survival  period;  or (B)
                    Adverse  Consequences  are  suffered  by any  of the  Seller
                    Indemnified  Parties in connection  with the Tools  Business
                    Shut-Down,  then each of the  Sellers  agrees  to  severally
                    indemnify the Seller Indemnified  Parties,  from and against
                    its Proportional Share of any Adverse  Consequences they may
                    suffer   through  and  after  the  date  of  the  claim  for
                    indemnification  (including  any  Adverse  Consequences  the
                    Seller  Indemnified  Parties may suffer after the end of any
                    applicable  survival period) resulting from, arising out of,
                    relating  to, in the  nature  of, or caused by the breach or
                    the   Tools   Business    Shut-Down   provided   that   such
                    indemnification  shall not exceed a cumulative  total of the
                    General Cap plus an additional  US$4,000,000  (the "IP Cap")
                    for a  total  amount  of  US$6,000,000  (the  "Total  Cap");
                    provided further,  however,  that the Sellers shall not have
                    any  obligation  to indemnify the Buyer from and against any
                    Adverse   Consequences   resulting  from,  arising  out  of,
                    relating  to, in the  nature  of, or caused by the breach of
                    any  representation,  warranty  or  covenant  of the Sellers
                    contained   in  this   Agreement   above  until  the  Seller
                    Indemnified  Parties  have  collectively   suffered  Adverse
                    Consequences  by reason of the  events in  sub-subparagraphs
                    8(b) (ii) (A)  and/or  (B)  above in excess of an  aggregate
                    threshold of US$200,000 plus any net cash proceeds  received
                    by the Target upon the  closing of a sale to a purchaser  of
                    the Tools Business  prior to July 31, 2000 and  specifically
                    including cash royalty payments forming part of the purchase
                    price for the Tools Business received from such purchaser by
                    the  Target  during the  period  for which the  Sellers  are
                    obligated  to  indemnify  the  Purchaser  under this Section
                    8(b)(ii)  (at which point the Sellers  will be  obligated to
                    indemnify  the  Buyer  from and  against  all  such  Adverse
                    Consequences relating back to the first dollar).

                    For greater  certainty,  the total  amount of all  indemnity
                    payments to be made  pursuant to Sections  8(b) (i) and (ii)
                    hereunder  shall at no time  exceed the Total Cap.  However,
                    any  indemnity   claims  made  by  the  Buyer   pursuant  to
                    subparagraph  8(b) (ii)  above  shall not  reduce  the total
                    amount of the  indemnity  available  for  payment  under the
                    General Cap until a total of  US$4,000,000  has been claimed
                    against the Total Cap. In addition,  the first  US$2,000,000
                    in aggregate of indemnity  claims made by the Buyer pursuant
                    to  either or both of  subparagraphs  8(b)(i)  and  8(b)(ii)
                    shall be satisfied by claiming  against the Escrowed  Shares
                    pursuant to the Escrow Agreement.

          (iii)     In the event any of the Sellers  breaches  any of his or its
                    covenants  in  Section  2(a)  above  or  any  of  his or its
                    representations  and warranties in Section 3(a) above,  and,
                    if  there  is an  applicable  survival  period  pursuant  to
                    Section  8(a) above,  provided  that the Seller  Indemnified
                    Parties  makes a written claim for  indemnification  against
                    the Seller  pursuant  to Section  11(h)  below  within  such
                    survival  period,  then the Seller  agrees to indemnify  the
                    Seller Indemnified  Parties from and against the entirety of
                    any Adverse  Consequences the Seller Indemnified Parties may
                    suffer   through  and  after  the  date  of  the  claim  for
                    indemnification  (including  any  Adverse  Consequences  the
                    Buyer may suffer  after the end of any  applicable  survival
                    period) resulting from,  arising out of, relating to, in the
                    nature  of,  or  caused by the  breach;  provided  that such
                    indemnification  shall not exceed a cumulative  total amount
                    for each Seller equal to such Seller's Proportional Share of
                    the  Purchase  Price less any amounts paid by such Seller to
                    any Seller  Indemnified  Parties pursuant to Section 8(b)(i)
                    and (ii).

     (c)  Indemnification  Provisions  for Benefit of the Sellers.  In the event
the  Buyer  breaches  any  of its  representations,  warranties,  and  covenants
contained herein or any certificate,  document or agreement delivered or entered
into at the Closing,  and, if there is an applicable survival period pursuant to
Section 8(a) above,  provided  that any of the Sellers makes a written claim for
indemnification  against the Buyer  pursuant to Section  11(h) below within such
survival period, then the Buyer agrees to indemnify each of the Sellers from and
against the entirety of any Adverse  Consequences  the Seller may suffer through
and  after  the date of the claim for  indemnification  (including  any  Adverse
Consequences  the  Seller may suffer  after the end of any  applicable  survival
period) resulting from, arising out of, relating to, in the nature of, or caused
by the breach (or the alleged breach).

     (d)  Matters Involving Third Parties.

          (i)       If any third party shall notify any Party (the  "Indemnified
                    Party") with  respect to any matter (a "Third Party  Claim")
                    which may give rise to a claim for  indemnification  against
                    any  other  Party  (the  "Indemnifying  Party")  under  this
                    Section 8, then the Indemnified  Party shall promptly notify
                    each  Indemnifying  Party  thereof  in  writing;   provided,
                    however,  that no delay on the part of the Indemnified Party
                    in  notifying  any  Indemnifying  Party  shall  relieve  the
                    Indemnifying Party from any obligation hereunder unless (and
                    then solely to the extent) the Indemnifying Party thereby is
                    prejudiced.

          (ii)      Any  Indemnifying  Party  will have the right to defend  the
                    Indemnified Party against the Third Party Claim with counsel
                    of its choice  reasonably  satisfactory  to the  Indemnified
                    Party so long as (A) the  Indemnifying  Party  notifies  the
                    Indemnified  Party  in  writing  within  15 days  after  the
                    Indemnified  Party has given notice of the Third Party Claim
                    that the  Indemnifying  Party will indemnify the Indemnified
                    Party  from  and  against   the   entirety  of  any  Adverse
                    Consequences  the  Indemnified  Party may




                                      -40-

                    suffer  resulting from,  arising out of, relating to, in the
                    nature  of,  or caused by the  Third  Party  Claim,  (B) the
                    Indemnifying  Party  provides  the  Indemnified  Party  with
                    evidence reasonably acceptable to the Indemnified Party that
                    the Indemnifying Party will have the financial  resources to
                    defend  against  the  Third  Party  Claim  and  fulfill  its
                    indemnification  obligations hereunder,  (C) the Third Party
                    Claim  involves  only  money  damages  and  does not seek an
                    injunction or other equitable relief,  (D) settlement of, or
                    an adverse  judgment  with respect to, the Third Party Claim
                    is not, in the good faith judgment of the Indemnified Party,
                    likely  to  establish  a  presidential  custom  or  practice
                    materially  adverse to the continuing  business interests of
                    the  Indemnified  Party,  and  (E)  the  Indemnifying  Party
                    conducts  the defense of the Third Party Claim  actively and
                    diligently.

          (iii)     So long as the Indemnifying  Party is conducting the defense
                    of the Third Party Claim in accordance with Section 8(d)(ii)
                    above,  (A)  the  Indemnified   Party  may  retain  separate
                    co-counsel at its sole cost and expense and  participate  in
                    the defense of the Third Party  Claim,  (B) the  Indemnified
                    Party will not consent to the entry of any judgment or enter
                    into any  settlement  with  respect to the Third Party Claim
                    without the prior written consent of the Indemnifying  Party
                    (not to be withheld unreasonably),  and (C) the Indemnifying
                    Party will not consent to the entry of any judgment or enter
                    into any  settlement  with  respect to the Third Party Claim
                    without the prior written consent of the  Indemnified  Party
                    (not to be withheld unreasonably).

          (iv)      In the event any of the conditions in Section 8(d)(ii) above
                    is or  becomes  unsatisfied,  however,  (A) the  Indemnified
                    Party may defend  against,  and  consent to the entry of any
                    judgment or enter into any  settlement  with respect to, the
                    Third  Party  Claim in any  manner  it  reasonably  may deem
                    appropriate  (and the  Indemnified  Party  need not  consult
                    with, or obtain any consent from, any Indemnifying  Party in
                    connection  therewith),  (B) the  Indemnifying  Parties will
                    reimburse the  Indemnified  Party promptly and  periodically
                    for the costs of  defending  against  the Third  Party Claim
                    (including reasonable attorneys' fees and expenses), and (C)
                    the  Indemnifying  Parties will remain  responsible  for any
                    Adverse   Consequences  the  Indemnified  Party  may  suffer
                    resulting  from,  arising out of, relating to, in the nature
                    of, or caused by the Third Party Claim to the fullest extent
                    provided in this Section 8.

     (e)  Treatment of Payments. All indemnification payments under this Section
8 shall be deemed adjustments to the Purchase Price.

     (f)  Exclusive  Remedy.  Without prejudice to Sections 10(c) and 11(o), the
Parties  hereto  acknowledge  and  agree  that  the  foregoing   indemnification
provisions in this Section 8 shall be the exclusive  remedy of the Buyer and the
Seller  with  respect to the  Target,  its  Subsidiaries,  and the  transactions
contemplated  by this  Agreement.  Each of the Sellers hereby




                                      -41-
<PAGE>

releases  each,  and  agrees  that he,  she or it will not  make any  claim  for
indemnification against any, of the Target and its Subsidiaries by reason of the
fact  that he or it was a  director,  officer,  employee,  or  agent of any such
entity or was serving at the  request of any such entity as a partner,  trustee,
director,  officer,  employee, or agent of another entity (whether such claim is
for judgments,  damages,  penalties,  fines, costs,  amounts paid in settlement,
losses,  expenses,  or  otherwise  and  whether  such claim is  pursuant  to any
statute,  charter  document,  bylaw,  agreement,  or  otherwise),  and,  without
limiting the generality of the foregoing,  including with respect to any action,
suit, proceeding,  complaint, claim, or demand brought by the Buyer against such
Seller (whether such action, suit,  proceeding,  complaint,  claim, or demand is
pursuant to this Agreement, Applicable Law, or otherwise).

9.   Tax Matters.

     The following  provisions shall govern the allocation of  responsibility as
between Buyer and Sellers for certain Tax matters following the Closing Date:

     (a)  Tax Returns.  Buyer shall  prepare or cause to be prepared and file or
cause to be filed all Tax  Returns for the Target and its  Subsidiaries  for all
periods ending on or prior to the Closing Date which are filed after the Closing
Date.

     (b)  Cooperation on Tax Matters.

          (i)       The Buyer and the Sellers shall  cooperate  fully, as and to
                    the  extent  reasonably  requested  by the other  party,  in
                    connection  with the filing of Tax Returns  pursuant to this
                    Section and any audit,  litigation or other  proceeding with
                    respect  to  Taxes.   Such  cooperation  shall  include  the
                    retention and (upon the other party's request) the provision
                    of records and information which are reasonably  relevant to
                    any such audit,  litigation or other  proceeding  and making
                    employees  available  on  a  mutually  convenient  basis  to
                    provide  additional   information  and  explanation  of  any
                    material  provided  hereunder.  The  Buyer  and the  Sellers
                    agree, or shall cause the Target and its  Subsidiaries,  (A)
                    to retain all books and records  with respect to Tax matters
                    pertinent to the Target and its Subsidiaries relating to any
                    taxable period  beginning  before the Closing Date until the
                    expiration of the statute of limitations (and, to the extent
                    notified by Buyer or Sellers, any extensions thereof) of the
                    respective  taxable  periods,  and to  abide  by all  record
                    retention agreements entered into with any taxing authority,
                    and (B) to give the other party  reasonable  written  notice
                    prior to  transferring,  destroying or  discarding  any such
                    books and records and, if the other party so  requests,  the
                    Target and its Subsidiaries or Sellers,  as the case may be,
                    shall allow the other party to take possession of such books
                    and records.

          (ii)      Buyer and Seller further agree,  upon request,  to use their
                    best  efforts to obtain any  certificate  or other  document
                    from any  governmental  authority or any other Person as may
                    be necessary to mitigate,  reduce or eliminate




                                      -42-
<PAGE>

                    any Tax that could be imposed  (including,  but not  limited
                    to, with respect to the transactions contemplated hereby).

     (c)  Tax Sharing  Agreements.  The Sellers represent and warrant that there
are no tax sharing agreements or similar agreements with respect to or involving
the Target and its Subsidiaries.

     (d)  Certain  Taxes.  All  transfer,   documentary,   sales,   use,  stamp,
registration  and  other  such  Taxes  and fees  (including  any  penalties  and
interest)  incurred  by any one or more of the Sellers in  connection  with this
Agreement are the  responsibility of and shall be paid by such Sellers when due,
and Sellers will, at their own expense, file all necessary Tax Returns and other
documentation with respect to all such transfer, documentary, sales, use, stamp,
registration and other Taxes and fees, and, if required by Applicable Law, Buyer
will,  and will cause its  affiliates  to, join in the execution of any such Tax
Returns and other documentation.

     (e)  Section 116  Certificate.  If each of the Sellers that is not resident
in Canada (collectively the "Non-Resident  Sellers") has not provided Buyer with
a certificate  (the  "Certificate")  issued by the Minister of National  Revenue
evidencing compliance with the provisions of Section 116 of the ITA prior to the
Closing,  Buyer will  withhold an amount  equal to 33 1/3 % of the  Non-Resident
Sellers' collective proportional share of the Purchase Price payable pursuant to
paragraph 2(b) hereof until the earlier of:

          (i)       the last day of the month  following  the month in which the
                    Closing occurs (the "Filing Date"); or

          (ii)      the  date  upon  which  each  of  the  Non-Resident  Sellers
                    delivers a Certificate to Buyer.

Upon receipt of the Certificate prior to the Filing Date, Buyer will be required
to immediately  pay the withheld  amounts to Clark,  Wilson who will receive the
same on  behalf  of each of the  Non-Resident  Sellers.  In the  event  that the
Certificate  is not  delivered as aforesaid  prior to the Filing Date Buyer will
remit the withheld amounts to the Receive General of Canada,  whose receipt will
discharge  Buyer from any liability to the  Non-Resident  Sellers or any of them
for the funds so remitted.

10.  Termination.

     (a)  Termination  of Agreement.  Certain of the Parties may terminate  this
Agreement as provided below:

          (i)       the Buyer and the Sellers may  terminate  this  Agreement by
                    mutual written consent at any time prior to the Closing;

          (ii)      the Buyer may  terminate  this  Agreement by giving  written
                    notice to the  Sellers at any time prior to the  Closing (A)
                    in the event any of the Sellers has  breached  any  material
                    representation,  warranty,  or  covenant  contained  in this
                    Agreement  in any material  respect,  the Buyer has notified
                    the  Seller of the  breach,  and the  breach  has  continued
                    without  cure for a period of 10




                                      -43-
<PAGE>

                    days after the notice of breach or (B) if the Closing  shall
                    not have  occurred on or before June 30, 2000,  by reason of
                    the failure of any  condition  precedent  under Section 7(a)
                    hereof (unless the failure results  primarily from the Buyer
                    itself breaching any representation,  warranty,  or covenant
                    contained in this Agreement);

          (iii)     Sellers holding  collectively greater than 66% of the Target
                    Common  Shares,  but not  individually,  may terminate  this
                    Agreement  with  respect  to all of the  Sellers  by  giving
                    written notice to the Buyer at any time prior to the Closing
                    (A) in  the  event  the  Buyer  has  breached  any  material
                    representation,  warranty,  or  covenant  contained  in this
                    Agreement in any material respect, the Sellers have notified
                    the  Buyer  of the  breach,  and the  breach  has  continued
                    without  cure for a period of 10 days  after  the  notice of
                    breach or (B) if the Closing  shall not have  occurred on or
                    before  June 30,  2000,  by  reason  of the  failure  of any
                    condition  precedent  under Section 7(b) hereof  (unless (i)
                    the condition precedent in Section 7(a)(xiii) shall not have
                    been  satisfied or waived by the Buyer by that time in which
                    case the Sellers' right to terminate this Agreement pursuant
                    to  this  Section  10(a)(iii)(B)  shall  only  arise  if the
                    Closing  shall not have  occurred on or before July 31, 2000
                    rather  than  June 30,  2000;  or (ii) the  failure  results
                    primarily from any of the Sellers  themselves  breaching any
                    representation,  warranty,  or  covenant  contained  in this
                    Agreement); and

          (iv)      the Buyer may  terminate  this  Agreement by giving  written
                    notice to the  Sellers at any time prior to 5:00 p.m. on the
                    tenth day after execution by the Buyer of this Agreement, if
                    the Buyer is not  reasonably  satisfied  with the results of
                    its continuing business,  legal and accounting due diligence
                    regarding the Target and its Subsidiaries.

     (b)  Effect of  Termination.  Subject to Section 10(c) below,  if any Party
terminates  this  Agreement  pursuant  to Section  10(a)  above,  all rights and
obligations of all the Parties  hereunder shall terminate  without any liability
of any Party to any other Party;  provided,  however,  that the  confidentiality
provisions contained in Section 5(e) above shall survive termination.

     (c)  Breakup  Fee.  As the sole and  exclusive  remedy  to the  terminating
Party:

          (i)       if  the  Buyer   terminates  this  Agreement  under  Section
                    10(a)(ii)(A) above for any reason, and the Sellers could not
                    themselves    terminate   this   Agreement   under   Section
                    10(a)(iii)(A)  above each of the Sellers shall pay the Buyer
                    their respective Proportional Share of US$500,000; or

          (ii)      if  the  Sellers  terminate  this  Agreement  under  Section
                    10(a)(iii)(A)  above for any reason, and the Buyer could not
                    itself  terminate this Agreement under Section  10(a)(ii)(A)
                    above, the Buyer shall pay the Sellers  collectively and not
                    individually US$500,000.




                                      -44-
<PAGE>

     Any payment  required to be made  pursuant to this  Section  10(c) shall be
     made not later than two business days after delivery to the of the relevant
     termination  notice,  and  shall be made by wire  transfer  of  immediately
     available funds to an account designated by terminating  Party,  payment by
     the buyer to the  designated  Seller  described  in  Section  2(i) shall be
     deemed to be payment to all the Sellers.

11.  Miscellaneous.

     (a)  Nature of Certain Obligations.

          (i)       The  covenants  of each of the Sellers in Section 2(a) above
                    concerning  the sale of his, her or its Target Shares to the
                    Buyer and the  representations and warranties of each of the
                    Sellers in Section 3(a) above concerning the transaction are
                    several  obligations.  This means that the particular Seller
                    making the  representation,  warranty,  or covenant  will be
                    solely responsible to the extent provided in Section 8 above
                    for any  Adverse  Consequences  the  Buyer  may  suffer as a
                    result of any breach thereof.

          (ii)      The  remainder  of  the  representations,   warranties,  and
                    covenants   in  this   Agreement   are  joint  and   several
                    obligations. This means that each Seller will be responsible
                    to the extent  provided in Section 8 above for the  entirety
                    of any Adverse Consequences the Buyer may suffer as a result
                    of any breach thereof.

     (b)  Press  Releases  and Public  Announcements.  The Sellers  agree not to
issue any press release or make any public announcement  relating to the subject
matter of this Agreement prior to the Closing without the prior written approval
of the Buyer;  provided,  however, that any Seller which is a public company may
make any public  disclosure that is required by Applicable Law or any listing or
trading agreement concerning its publicly-traded  securities (in which case such
Seller will consult with the Buyer prior to making the disclosure). In addition,
the Sellers agree to allow the Buyer to dictate the positioning,  whether verbal
or written, of all public announcements related to this transaction.

     (c)  No  Third-Party  Beneficiaries.  This  Agreement  shall not confer any
rights or remedies  upon any Person other than the Parties and their  respective
successors  and permitted  assigns and, for purposes of Section 8(b) above,  the
Target,  Affiliates of the Buyer and the Target, and their officers,  directors,
employees and agents.

     (d)  Entire Agreement.  This Agreement (including the documents referred to
herein)  constitutes  the entire  agreement among the Parties and supersedes any
prior  understandings,  agreements,  or representations by or among the Parties,
written or oral,  to the extent they  related in any way to the  subject  matter
hereof.

     (e)  Succession and  Assignment.  This Agreement  shall be binding upon and
inure to the benefit of the Parties named herein and their respective successors
and permitted  assigns.  No Party may assign either this Agreement or any of his
or its rights,  interests,  or obligations  hereunder  without the prior written
approval of the Buyer and the Sellers; provided, however, that the Buyer may (i)
assign any or all of its rights and  interests  hereunder  to one or more of its




                                      -45-
<PAGE>

Affiliates,  and (ii)  designate  one or more of its  Affiliates  to perform its
obligations  hereunder (in any or all of which cases the Buyer nonetheless shall
remain responsible for the performance of all of its obligations hereunder).

     (f)  Counterparts.   This   Agreement  may  be  executed  in  one  or  more
counterparts (including separate signature pages by fax), each of which shall be
deemed an original but all of which  together will  constitute  one and the same
instrument.

     (g)  Headings.  The  section  headings  contained  in  this  Agreement  are
inserted  for  convenience  only and shall not affect in any way the  meaning or
interpretation of this Agreement.

     (h)  Notices.   All  notices,   requests,   demands,   claims,   and  other
communications hereunder will be in writing. Any notice, request, demand, claim,
or other  communication  hereunder  shall be deemed  duly given if (and then two

requested, postage prepaid, and addressed to the intended recipient as set forth

Any Party may send any notice,  request,  demand,  claim, or other communication
hereunder  to the  intended  recipient  at the address set forth above using any
other means (including personal delivery,  expedited courier, messenger service,
telecopy,  telex,  ordinary  mail,  or  electronic  mail),  but no such  notice,
request, demand, claim, or other communication shall be deemed to have been duly
given  unless and until it actually is received by the intended  recipient.  Any
Party may change the address to which notices,  requests,  demands,  claims, and
other  communications  hereunder are to be delivered by giving the other Parties
notice in the manner herein set forth.

     (i)  Governing  Law. This  Agreement  shall be governed by and construed in
accordance  with the laws of the province of British  Columbia,  and the laws of
Canada  applicable  therein,  without giving effect to any choice or conflict of
law provision or rule (whether of the province of British  Columbia or any other
jurisdiction)  that would cause the application of the laws of any  jurisdiction
other than the province of British Columbia.

     (j)  Dispute Resolution.  Any dispute,  controversy or claim arising out of
or relating to this  Agreement,  or the breach,  termination or invalidity of it
shall be settled by  arbitration  in  accordance  with the UNCITRAL  Arbitration
Rules in effect on the date of this Agreement. The appointing authority shall be
the British Columbia  International  Commercial Arbitration Centre. The place of
arbitration  shall  be  Vancouver,  British  Columbia,  Canada.  The  number  of
arbitrators  shall be one. The arbitrator shall be fully fluent in English.  The
arbitrator  will issue findings of fact and conclusions of law to support his or
her opinion.  Judgment upon the award  rendered by the arbitrator may be entered
by any court having jurisdiction thereof and enforced as any other judgment. The
arbitrator shall have the power,  but not the obligation,  to hire an



                                      -47-
<PAGE>

accounting firm or other professional  within the financial services industry as
an expert in order to assist the  arbitrator  in issuing  findings of fact.  The
arbitration  proceedings  and all discovery  shall be  confidential  and neither
party shall release any decision  rendered by the arbitrator to any third party.
Discovery  shall be limited to that which is  directly  relevant to the claim or
controversy  and to  key  documents  and  witnesses  that  are  substantive  and
reasonably  necessary  to  establish  a  party's  claim  or  defense.   Whenever
reasonably possible and unless manifestly prejudicial or unfair, affidavits will
be substituted for direct testimony.  Notwithstanding any of the foregoing,  the
Parties  recognize that certain  business  relationships  could give rise to the
need for one or more of the Parties to seek  emergency,  provisional  or summary
injunctive  relief.  Immediately  following the issuance of any such relief, the
Parties agree to the stay of any judicial proceedings pending arbitration of all
underlying claims between the parties.

     (k)  Amendments  and  Waivers.  No  amendment  of  any  provision  of  this
Agreement  shall be valid  unless the same shall be in writing and signed by the
Buyer and the Sellers. No waiver by any Party of any default, misrepresentation,
or breach of warranty or covenant  hereunder,  whether intentional or not, shall
be deemed to extend to any prior or subsequent  default,  misrepresentation,  or
breach of warranty or covenant hereunder or affect in any way any rights arising
by virtue of any prior or subsequent such occurrence.

     (l)  Severability.  Any term or provision of this Agreement that is invalid
or  unenforceable  in any  situation  in any  jurisdiction  shall not affect the
validity or  enforceability  of the remaining terms and provisions hereof or the
validity or  enforceability  of the  offending  term or  provision  in any other
situation or in any other jurisdiction.

     (m)  Expenses.  Each of the Parties,  the Target, and its Subsidiaries will
bear his or its own costs  and  expenses  (including  legal  fees and  expenses)
incurred in connection  with this  Agreement and the  transactions  contemplated
hereby.  Notwithstanding the foregoing, Target may pay reasonable legal fees and
expenses of the Shareholders  incurred in connection with this Agreement and the
transactions contemplated hereby.

     (n)  Construction. The Parties have participated jointly in the negotiation
and drafting of this Agreement.  In the event an ambiguity or question of intent
or  interpretation  arises,  this  Agreement  shall be  construed  as if drafted
jointly  by the  Parties  and no  presumption  or  burden of proof  shall  arise
favoring  or  disfavoring  any Party by virtue of the  authorship  of any of the
provisions of this Agreement. The language used in this Agreement will be deemed
to be the language chosen by the Parties to express their mutual intent,  and no
rule of strict  construction will be applied.  Any reference to any law shall be
deemed also to refer to all rules and regulations promulgated thereunder, unless
the  context  requires  otherwise.  The word  "including"  shall mean  including
without  limitation.  Singular  words,  terms and usage  shall be  construed  to
include the  plural,  and vice versa,  as the context  permits.  The phrase "the
Target and its Subsidiaries" and variations of such phrase shall be construed to
include,  as the context  permits any of such  Persons and not merely the Target
and its Subsidiaries taken as a whole (unless expressly so stated).  The Parties
intend that each representation,  warranty,  and covenant contained herein shall
have  independent  significance.  If any Party has breached any  representation,
warranty,  or  covenant  contained  herein in any  respect,  the fact that there
exists  another  representation,  warranty,  or  covenant  relating  to the same
subject matter  (regardless  of




                                      -48-
<PAGE>

the relative levels of  specificity)  which the Party has not breached shall not
detract  from or  mitigate  the fact  that the  Party is in  breach of the first
representation, warranty, or covenant.

     (o)  Specific Performance. Each of the Parties acknowledges and agrees that
the  other  Parties  would  be  damaged  irreparably  in  the  event  any of the
provisions of this Agreement are not performed in accordance with their specific
terms or otherwise are breached.  Accordingly,  each of the Parties  agrees that
the other Parties shall be entitled to an injunction or  injunctions  to prevent
breaches of the  provisions of this Agreement and to enforce  specifically  this
Agreement and the terms and provisions  hereof,  in addition to any other remedy
to which they may be entitled, at law or in equity.

     (p)  Time of Essence.  With regard to all dates and time  periods set forth
in the Agreement, time is of the essence.

     (q)  Incorporation of Exhibits and Schedules.  The Schedules  identified in
this Agreement are incorporated herein by reference and made a part hereof.


     IN WITNESS WHEREOF,  the Parties hereto have executed this Agreement on the
date first above written.

     THIS SHARE PURCHASE AGREEMENT made between PIVOTAL CORPORATION  ("Pivotal")
and the undersigned  (the "Seller"),  a shareholder of Simba  Technologies  Inc.
("Simba");

     WITNESSES THAT WHEREAS the Seller owns the outstanding shares of Simba (the
"Simba Shares") as set out in Part 1 of the attached Schedule A;

     NOW THEREFORE in consideration  of the mutual promises and  representations
contained in this Agreement, the parties hereto agree as follows:

1.   Purchase and Sale Transaction

1.1  On and  subject  to the terms and  conditions  of this  Agreement,  Pivotal
agrees to purchase  from the Seller and the Seller agrees to sell to Pivotal all
of the  Seller's  Simba  Shares  for  the  purchase  price  set out in Part 1 of
Schedule A (the "Purchase Price").

1.2  The  Purchase  Price  shall be paid by Pivotal to the Seller by delivery of
the number of shares of Pivotal  set out in Part 1 of  Schedule A (the  "Pivotal
Shares") at a closing (the "Closing") to be held simultaneously with the closing

Agreement").

2.   Appointment of Representative Seller

2.1  The Seller hereby irrevocably appoints Kirk Herrington (the "Representative
Seller") as the  Seller's  agent for the  purposes of: (a) delivery of the Simba
Shares to Pivotal; (b) the delivery of the Pivotal Shares to the Seller; and (c)
negotiating  and  executing  the  Registration  Rights  Agreement  (attached  as

authority and delegates the responsibility to the Representative  Seller to make
such decisions and take such actions as may be necessary or desirable to effect:

including  the  waiver  of any term or  condition  of  Closing  in favour of the
Seller,  other than  payment of the  Purchase  Price;  and (b) the  Registration

3.   Representations and Warranties of the Seller

     The Seller represents and warrants to Pivotal that the statements contained
in this Section 3 are correct and  complete as of the date of execution  hereof,
and shall be correct  and  complete  as of the  Closing,  as though  made at the
Closing:

     (a)  Organization of Certain Sellers.  If the Seller is a corporation,  the
          Seller is duly organized, validly existing, and in good standing under
          the laws of the jurisdiction of its incorporation.

     (b)  Authorization of Transaction.  The Seller has full power and authority
          (including,  if the Seller is a corporation,  full corporate power and
          authority)  to execute and deliver this  Agreement and to perform his,
          her or its obligations hereunder. This Agreement constitutes the valid
          and  legally  binding  obligation  of the  Seller.  The  Seller is not
          required  to obtain any  authorization,  consent,  or  approval of any
          person,  including  any  court  or  governmental  agency,  in order to
          complete the transactions contemplated by this Agreement.

     (c)  Noncontravention.  Neither  the  execution  and the  delivery  of this
          Agreement, nor the completion of the transactions contemplated hereby,
          will violate any injunction,  judgment, order, decree, ruling, charge,
          or other restriction of any governmental  agency or court to which the
          Seller is subject or, if the Seller is a corporation, any provision of
          its charter or bylaws.

     (d)  Simba  Shares.  The Seller owns the number of Simba  Shares set out in
          Schedule  A free and  clear of  security  interests,  liens,  charges,
          encumbrances, spousal or community property rights, options, warrants,
          purchase rights, contracts, commitments,  equities, claims, demands or
          any other  restrictions on transfer (other than any restrictions under
          applicable laws relating to securities).  The Seller is not a party to
          any option,  warrant,  purchase right, or other contract or commitment
          that could require the Seller to sell, transfer,  or otherwise dispose
          of any Simba Shares to any other person.  The Seller is not a party to
          any voting trust,  proxy,  or other  agreement or  understanding  with
          respect to the voting of any shares of Simba.

     (e)  Options. The Seller has exercised, or will on or prior to Closing have
          exercised,  all of the vested options or warrants  described in Part 2
          of Schedule A to this  Agreement,  and the Simba  Shares to be sold to
          Pivotal  under this  Agreement  include the Simba  Shares  received or
          receivable  on such  exercise.  The number of options or warrants  set
          forth next to the  Seller's  name in Part 3 of  Schedule A  accurately
          reflects all of the Seller's other options, warrants, purchase rights,
          subscription  rights,  conversion  rights,  exchange rights,  or other
          contracts or commitments  that could require Simba to issue any of its
          securities.

     (f)  Residency.  The Seller  [please check one of the following] [ ---- is]
          [---- is not] a non-resident  of Canada for purposes of the Income Tax
          Act (Canada).

          representations and warranties set out in Schedule B-2.

4.   Representations and Warranties of Pivotal

     Pivotal  agrees that the same  representations  and  warranties  concerning
Pivotal  that are made to the  Simba  shareholders  in the  Main  Agreement  are
extended to the Seller with respect to Pivotal and the Pivotal Shares.

5.   Section 116 Certificate

     If the Seller has  indicated  in Section 3(f) above that it is not resident
in  Canada  (a  "Non-Resident  Seller")  and has  not  provided  Pivotal  with a
certificate  (the  "Certificate")  issued by the  Minister of  National  Revenue
evidencing  compliance  with the provisions of Section 116 of the Income Tax Act
(Canada) prior to the Closing, Pivotal will withhold an amount equal to 33 1/3 %
of the Purchase  Price payable to the Seller  pursuant to Section 1 hereof until
the earlier of:

     (i)  the last day of the month  following  the  month in which the  Closing
          occurs (the "Filing Date"); or

     (ii) the date upon which the Non-Resident  Seller delivers a Certificate to
          Pivotal.

Upon  receipt of the  Certificate  prior to the  Filing  Date,  Pivotal  will be
required to immediately pay the withheld  amounts to Clark,  Wilson,  Barristers
and Solicitors  who will receive the same on behalf of the Seller.  In the event
that the  Certificate  is not  delivered as aforesaid  prior to the Filing Date,
Pivotal will remit the withheld amounts to the Receive General of Canada,  whose
receipt will discharge Pivotal from any liability to the Seller for the funds so
remitted.

6.   Maximum Liability

     The maximum aggregate  liability of the Seller to the Buyer for claims made
by the Buyer  that  arise as a result  of a breach  by the  Seller of any of its
representations  and warranties  contained in Section 3 above,  is limited to an
amount equal to the Purchase Price.

7.   Conditions to Closing

     The Closing will  indirectly be subject to all the terms and  conditions of
closing that are set out in the Main Agreement,  in that no purchase and sale of
the Simba  Shares will be  completed  unless and until the purchase of shares of
Simba under the Main Agreement is




                                      -3-
<PAGE>

completed.  The Closing will also be subject to the Seller's representations and
warranties set out in section 3 above being true and correct as at the Closing.

8.   Legends

     Each  certificate  of  Pivotal  Shares  delivered  at the  Closing  will be
imprinted with legends substantially in the following form:

     (a)  U.S. Legend

          The  securities  represented  hereby  have  not  been  and will not be
          registered under the United States  Securities Act of 1933, as amended
          (the  "Securities   Act").  The  holder  hereof,  by  purchasing  such
          securities, agrees for the benefit of the company that such securities
          may be offered, sold or otherwise transferred only (a) to the company,
          (b)  outside  the  United  States  in  accordance  with  Rule  904  of
          Regulation S under the Securities Act, (c) inside the United States in
          accordance with Rule 144 under the Securities  Act, if applicable,  or
          (d) in a transaction that is otherwise exempt from registration  under
          the Securities Act and applicable state securities laws, provided that
          prior to such sale the  company  shall  have  received  an  opinion of
          counsel of recognized standing, in form and substance  satisfactory to
          it, as to the availability of an exemption.  The holder hereof further
          agrees  for the  benefit  of the  company  that it may not  engage  in
          hedging   transactions  with  respect  to  the  securities  except  in
          compliance with the Securities Act.  Delivery of this  certificate may
          not constitute  "good delivery" in settlement of transactions on stock
          exchanges in Canada.  Provided that the company is a "foreign  issuer"
          within the meaning of  Regulation  S under the  Securities  Act at the
          time of sale, a new certificate,  bearing no legend, delivery of which
          will constitute  "good  delivery," may be obtained from American Stock
          Transfer & Trust Company upon delivery of this  certificate and a duly
          executed  declaration,  in  a  form  satisfactory  to  American  Stock
          Transfer & Trust Company and the company,  to the effect that the sale
          of the securities  represented hereby is being made in compliance with
          rule 904 of Regulation S under the Securities Act.

     (b)  Canadian Legend

          The  shares  represented  by this  certificate  are  subject to a hold
          period and may not be traded in British  Columbia  until [date] except
          as permitted by the  Securities  Act (British  Columbia) and the rules
          thereunder.

Each holder desiring to transfer  Pivotal Shares first must furnish Pivotal with
(i) a written opinion  reasonably  satisfactory to Pivotal in form and substance
from counsel  reasonably  satisfactory to Pivotal by reason of experience to the
effect  that the  holder  may  transfer  Pivotal  Shares  as  desired  without a
prospectus under the Securities Act (British Columbia) or registration under the
U.S.  Securities  Act of 1933 and (ii) a  written  undertaking  executed  by the
desired  transferee  reasonably  satisfactory  to Pivotal in form and  substance
agreeing to be bound by the restrictions on transfer contained herein.

9.   Termination

     This Agreement may not be unilaterally terminated by either party but shall
be automatically terminated,  without any other steps or advance notices, in the
event that the Main Agreement is terminated for any reason by any party thereto.
Pivotal  will,  however  provide  notice  to  Seller's  Representative  of  such
termination.  Neither  party shall have any liability or  responsibility  of any
nature whatsoever to the other party in connection with any such termination.

10.  Standstill Agreement

     The Seller  agrees  that until two full days  following  the earlier of the
Closing or receipt from Seller's Representative of notice of termination of this
Agreement, the Seller shall not purchase or sell any shares of Pivotal.

     The Seller agrees to keep strictly confidential the existence and nature of
this Agreement and the Main Agreement. Notwithstanding this obligation of strict
confidentiality,  the Seller may consult with his, her or its legal,  accounting
or financial advisor with respect to this transaction provided that such advisor
is made aware of the Seller's obligation of confidentiality.

12.  Notices and Delivery

     All notices, deliveries and other communications pursuant to this Agreement
must  be  in  writing  and  will  be  validly  delivered  if  delivered  to  the
Representative  Seller  at the  head  office  of  Simba  in  Vancouver,  British
Columbia.

13.  Miscellaneous

     (a)  Entire Agreement.  This Agreement (including the documents referred to
          herein)  constitutes  the  entire  agreement  among  the  parties  and
          supersedes any prior understandings, agreements, or representations by
          or among the parties,  written or oral,  to the extent they related in
          any way to the subject matter hereof.

     (b)  Succession and  Assignment.  This Agreement  shall be binding upon and
          inure to the benefit of the parties  and their  respective  successors
          and permitted assigns. The Seller may not assign this Agreement or any
          of the Seller's rights,  interests,  or obligations  hereunder without
          the prior written  approval of Pivotal.  Pivotal may (i) assign any or
          all of its  rights  and  interests  hereunder  to one or  more  of its
          Affiliates,  and  (ii)  designate  one or  more of its  Affiliates  to
          perform  its  obligations  hereunder  (in  any or all of  which  cases
          Pivotal  nonetheless  shall remain  responsible for the performance of
          all of its obligations hereunder).

          accordance with the laws of the province of British Columbia,  and the
          laws of Canada applicable therein.

     (d)  Amendments  and  Waivers.  No  amendment  of  any  provision  of  this
          Agreement  shall be valid  unless  the same  shall be in  writing  and
          signed by Pivotal  and the  Seller or the  Representative  Seller.  No
          waiver of any  default,  misrepresentation,  or breach of  warranty or
          covenant  hereunder,  whether  intentional  or not, shall be deemed to
          extend  to any  prior or  subsequent  default,  misrepresentation,  or
          breach of  warranty  or  covenant  hereunder  or affect in any way any
          rights arising by virtue of any prior or subsequent occurrence.

     (e)  Expenses.  Each of the  parties  will bear its own costs and  expenses
          incurred  in  connection  with  this  Agreement  and the  transactions
          contemplated hereby.

     Section 2. Restrictions on Transfer.

     (a)  Restrictions.  Each  Holder  agrees  that such  Holder  will not sell,
assign, transfer or otherwise dispose of (each, a "Transfer") any of the Pivotal
Shares (or any interest therein) except upon the terms and conditions  specified
herein,  and such  Holder  will  cause any  subsequent  holder of such  Holder's
Pivotal Shares to agree to take and hold the Pivotal Shares subject to the terms
and  conditions of this Agreement if such Pivotal Shares are required to include
a legend pursuant to Section 2(b) hereof.

     (b) Legend.  Each  certificate  representing  Pivotal  Shares issued to the
Holders or to any  subsequent  holder of such shares  shall  include a legend in

be  required if (i) a Transfer  is being made (a) in  connection  with a sale of
Pivotal Shares  registered  under the Securities  Act, (b) in connection  with a
sale of Pivotal  Shares in compliance  with Rule 144 under the Securities Act or
(c) in connection  with a sale of Pivotal Shares in compliance  with Rule 904 of
Regulation  S under the  Securities  Act (each,  a "Public  Sale"),  or (ii) the
opinion of counsel  referred to in Section 2(d) hereof is to the further  effect
that neither such legend nor the  restrictions on transfer in this Section 2 are
required in order to ensure compliance with the Securities Act:

     THE SECURITIES  REPRESENTED HEREBY HAVE NOT BEEN AND WILL NOT BE REGISTERED
     UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
     ACT").  THE HOLDER HEREOF,  BY PURCHASING SUCH  SECURITIES,  AGREES FOR THE
     BENEFIT  OF THE  COMPANY  THAT  SUCH  SECURITIES  MAY BE  OFFERED,  SOLD OR
     OTHERWISE  TRANSFERRED  ONLY (A) TO THE  COMPANY,  (B)  OUTSIDE  THE UNITED
     STATES IN  ACCORDANCE  WITH RULE 904 OF  REGULATION S UNDER THE  SECURITIES

<PAGE>

     ACCORDANCE WITH RULE 144 UNDER THE SECURITIES ACT, IF APPLICABLE, OR (D) IN
     A  TRANSACTION  THAT  IS  OTHERWISE  EXEMPT  FROM  REGISTRATION  UNDER  THE
     SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, PROVIDED THAT PRIOR TO
     SUCH SALE THE  COMPANY  SHALL  HAVE  RECEIVED  AN  OPINION  OF  COUNSEL  OF
     RECOGNIZED  STANDING,  IN FORM AND SUBSTANCE  SATISFACTORY TO IT, AS TO THE
     AVAILABILITY  OF AN  EXEMPTION.  THE HOLDER HEREOF  FURTHER  AGREES FOR THE
     BENEFIT OF THE COMPANY THAT IT MAY NOT ENGAGE IN HEDGING  TRANSACTIONS WITH
     RESPECT TO THE SECURITIES  EXCEPT IN COMPLIANCE  WITH THE  SECURITIES  ACT.
     DELIVERY  OF  THIS  CERTIFICATE  MAY  NOT  CONSTITUTE  "GOOD  DELIVERY"  IN
     SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.  PROVIDED THAT THE
     COMPANY IS A "FOREIGN  ISSUER" WITHIN THE MEANING OF REGULATION S UNDER THE
     SECURITIES ACT AT THE TIME OF SALE, A NEW  CERTIFICATE,  BEARING NO LEGEND,
     DELIVERY OF WHICH WILL  CONSTITUTE  "GOOD  DELIVERY,"  MAY BE OBTAINED FROM
     AMERICAN STOCK  TRANSFER & TRUST COMPANY UPON DELIVERY OF THIS  CERTIFICATE
     AND A DULY EXECUTED  DECLARATION,  IN A FORM SATISFACTORY TO AMERICAN STOCK
     TRANSFER & TRUST  COMPANY AND THE  COMPANY,  TO THE EFFECT THAT THE SALE OF
     THE SECURITIES REPRESENTED HEREBY IS BEING MADE IN COMPLIANCE WITH RULE 904
     OF REGULATION S UNDER THE SECURITIES ACT.

     (c)  Notices of  Transfer.  Prior to any  proposed  Transfer of any Pivotal
Shares other than pursuant to an offering  registered  under the Securities Act,
the Holder  proposing to make such Transfer shall give written notice to Pivotal
of such Holder's intention to effect such Transfer, which notice shall set forth
the date of such  proposed  Transfer.  Such Holder also shall furnish to Pivotal
(i) a written agreement by the proposed Transferee that it is taking and holding
the same subject to the terms and conditions specified in this Agreement, except
with  respect to any  Pivotal  Shares  which are being sold in a Public Sale and
(ii) except with respect to any Pivotal Shares which have been registered  under
the  Securities  Act,  a  written  opinion  of such  Holder's  counsel,  in form
reasonably satisfactory to Pivotal, to the effect that the proposed Transfer may
be effected without registration under the Securities Act.

     (d)  Termination of  Restrictions.  Except as provided in Section 2(a), the
restrictions  set  forth  in this  Section  2 shall  terminate  and  cease to be
effective  with  respect to any of the  Pivotal  Shares (i) upon the sale of any
such Pivotal Shares,  if the Pivotal Shares in respect of which such sale occurs
have been  registered  under the Securities Act and the sale is made pursuant to
the  Registration  Statement,  (ii) upon  receipt  by  Pivotal  of an opinion of
counsel  (in form and  substance  satisfactory  to  Pivotal)  to the effect that
compliance  with such  restrictions is not necessary in order to comply with the
Securities  Act with respect to the Transfer of such  Pivotal  Shares,  or (iii)
upon the expiration of the two-year  period referred to in Rule 144(k) under the
Securities Act (as such Rule may be amended from time to time),  if, pursuant to
Rule  144(k),  such  Holder was not an  "Affiliate"  of Pivotal (as such term is
defined in Rule 144(a) under the Securities  Act) at the time of the sale of the
Pivotal  Common  Shares  and has not been an  Affiliate  of  Pivotal  during the
preceding three months.

     Section 3. Registration under Securities Act; Indemnification.

     (a) Shelf-Registration.

          (i)  After  Pivotal  becomes  eligible  to  file a  short-form  resale
     registration  statement on Form F-3 or Form S-3,  Pivotal shall prepare and
     file with the Commission before September 30, 2000 (the date of such filing
     being hereinafter referred to as the "Filing Date"), a "shelf" registration
     statement on Form F-3 or Form S-3, in Pivotal's  sole  discretion,  (or, in
     Pivotal's sole discretion, on any appropriate form under the Securities Act
     as may then be available to Pivotal)  relating to the resale of the Pivotal
     Shares by the Holders in accordance  with the methods of  distribution  set
     forth in such registration statement (which shall not include,  without the
     consent of Pivotal  (which may be granted or  withheld  in  Pivotal's  sole
     discretion) an underwritten offering) and Rule 415 under the Securities Act
     (hereafter, the "Shelf Registration Statement"), and shall use commercially
     reasonable efforts to cause the Shelf Registration Statement to be declared
     effective by the Commission as soon as reasonably practicable thereafter.

          (ii) Restrictions on Eligibility to Participate in Shelf-Registration.
     If at the time of filing of the  shelf-registration  statement  pursuant to
     Section  3(a)(i),  Pivotal  is listed  for  trading  on The  Toronto  Stock
     Exchange  and an  individual  Holder is eligible to sell his or her Pivotal
     Shares pursuant to the exclusion from registration  provided by Rule 904 of
     Regulation S under the Securities  Act, that Holder will not be eligible to
     participate  in  the  shelf-registration  statement  described  in  Section
     3(a)(i).

          (iii)  Pivotal  shall be  obligated  to prepare,  file and cause to be
     effective only one (1) Shelf  Registration  Statement,  pursuant to Section
     3(a)(i).

          (iv) Effective Period.  Pivotal agrees to use commercially  reasonable
     efforts to keep the Shelf Registration Statement continuously effective for
     at least one hundred eighty (180) days or until the distribution  described
     in the  registration  statement has been  completed,  whichever is shorter,
     provided that the period for which the Shelf Registration Statement must be
     kept  effective  shall  be  extended  by one day for  every  day  sales  of
     securities  pursuant  to the Shelf  Registration  Statement  are  suspended
     pursuant to Section 3(a)(v) hereof.

          (v)  Black-out  Period.  Without  limiting the  provisions  of Section
     3(a)(iii),  each  holder  of  Registrable  Securities  agrees  that,  if so
     requested  by  Pivotal,  not to effect any offer or sale of Pivotal  Shares
     pursuant to the Shelf Registration  Statement,  or otherwise,  or engage in
     any hedging or other transaction intended to reduce or transfer the risk of
     ownership for any period deemed necessary (x) by Pivotal or any underwriter
     in connection  with the offering of Pivotal  Common Shares  pursuant to any
     demand  registration  rights granted to any other person or to the offering
     of Pivotal  Common  Shares by Pivotal for its own account or (y) by Pivotal
     in  connection  with any  proposal  or plan by  Pivotal  to  engage  in any
     material financing or material acquisition or disposition by Pivotal or any
     subsidiary thereof of the capital stock or substantially all the assets of




                                      -4-
<PAGE>


     any other  person  (other than in the  ordinary  course of  business),  any
     tender  offer  or  any  merger,  consolidation,  corporate  reorganization,
     strategic  partnership   arrangement  or  restructuring  or  other  similar
     transaction  (each, a "Business  Combination")  material to Pivotal and its
     subsidiaries  taken as a whole.  Any  period  within the  Effective  Period
     during  which  Pivotal  fails  to keep  the  Shelf  Registration  Statement
     effective and usable for resales of Pivotal Shares, or requires pursuant to
     this Section  3(a)(v)  that the Holders not effect sales of Pivotal  Shares
     pursuant to the Shelf Registration Statement, is hereafter referred to as a
     "Suspension  Period".  A Suspension  Period shall  commence on the date set
     forth in a  written  notice  by  Pivotal  to the  Holders  that  the  Shelf
     Registration  Statement  is no  longer  effective  or that  the  prospectus
     included  in the  Shelf  Registration  Statement  is no longer  usable  for
     resales of Pivotal Shares or, in the case of a suspension  pursuant to this
     Section  3(a)(v)  the date  specified  in the notice  delivered  by Pivotal
     pursuant  to this  Section  3(a)(v),  and  shall  end on the date when each
     Holder of Pivotal Shares covered by the Shelf Registration Statement either
     receives the copies of the supplemented or amended prospectus  contemplated
     by Section  3(c)(v)  or is  advised  in writing by Pivotal  that use of the
     prospectus  or sales may be  resumed.  Each  Holder also agrees that at any
     time such Holder is an employee of Pivotal,  such Holder will be subject to
     and comply with the policies of Pivotal  regarding  purchases  and sales of
     Pivotal  Common  Shares.  The Holders  acknowledge  that such policy may be
     changed by Pivotal from time to time.

     (b)  Piggyback Registration.

          (i) Each time  Pivotal  shall  determine  to  proceed  with the actual
     preparation and filing of a registration statement under the Securities Act
     in  connection  with the  proposed  offer  and sale for money of any of its
     securities by it or any of its security  holders (other than a registration
     statement on Form S-8, Form S-4 or other  limited  purpose  form),  Pivotal
     will give  written  notice of its  determination  to all record  holders of
     Registrable Securities.  Upon the written request of a record holder of any
     shares of  Registrable  Securities  given  within 30 days after the date of
     mailing of any such notice from  Pivotal,  Pivotal  will,  except as herein
     provided,  cause all the Registrable Securities,  the registration of which
     is  requested  to be included in such  registration  statement,  all to the
     extent requisite to permit the sale or other disposition by the prospective
     seller  or  sellers  of the  Registrable  Securities  to be so  registered;
     provided,  however,  that nothing herein shall prevent Pivotal from, at any
     time,  abandoning or delaying any  registration;  and provided further that
     Pivotal's  obligation under this Section 3(b) shall be subject to Pivotal's
     obligations  to any holder of  securities  which  shall  have  registration
     rights which limit or forbid the inclusion of the Registrable Securities in
     any Registration Statement.

          (ii) If any registration pursuant to this Section 3(b) is underwritten
     in whole or in part,  Pivotal may require that the  Registrable  Securities
     included in the  registration  be included in the  underwriting on the same
     terms and  conditions as the  securities  otherwise  being sold through the
     underwriters. If, in the good faith judgment of the managing underwriter of
     the Public  Offering,  the inclusion of all of the  Registrable  Securities
     originally  covered by requests for registration would reduce the number of
     shares to be offered by Pivotal or interfere with the successful  marketing
     of the shares offered by




                                      -5-
<PAGE>

     Pivotal,  the  number  of  Registrable  Securities  to be  included  in the
     Offering  may be  reduced  pro rata  among the  holders  of all  securities
     proposed to be included in this  registration,  in the proportion  that the
     number of common shares of Pivotal held by each holder proposing to include
     common shares in the  registration  statement  bears to the total number of
     common shares held by all such holders.

     (c)  Registration  Procedures.  If and whenever  Pivotal is required by the
provisions  of Sections  3(a) and 3(b) to effect the  registration  of shares of
Registrable  Securities  under the Securities Act, Pivotal will use commercially
reasonable  efforts  to effect  the  registration  and sale of such  Registrable
Securities in accordance with the intended  methods of disposition  specified by
the holders participating  therein.  Without limiting the foregoing,  Pivotal in
each such case will, as expeditiously as is commercially reasonable:

          (i) cause the  registration  statement and the related  prospectus and
     any  amendment  or  supplement  thereto,  as of the  effective  date of the
     registration statement,  or such amendment or supplement,  (A) to comply in
     all material  respects with the applicable  requirements  of the Securities
     Act and the rules and regulations of the Commission  promulgated  under the
     Securities  Act and (B) not to contain any untrue  statement  of a material
     fact or omit to state a  material  fact  required  to be stated  therein or
     necessary to make the statements therein not misleading;

          (ii) promptly prepare and file with the Commission such amendments and
     supplements  to the  registration  statement  and  the  prospectus  used in
     connection with the registration  statement as may be necessary to keep the
     registration  statement  effective and to comply with the provisions of the
     Securities  Act  with  respect  to  the   disposition  of  all  Registrable
     Securities covered by the registration  statement until the earlier of such
     time as all such Registrable Securities have been disposed of in accordance
     with the intended  methods of disposition by the Holder or Holders  thereof
     set forth in the registration  statement (which shall not include,  without
     the consent of Pivotal  (which may be granted or withheld in Pivotal's sole
     discretion) an underwritten  offering) or a date calculated as described in
     Section  3(a)(iii)  hereof;  provided  that if the  Board of  Directors  of
     Pivotal   determines   that   amending   the   registration   statement  or
     supplementing  the  prospectus  might  be  detrimental  to  Pivotal,   then
     notwithstanding  this Section  3(c)(ii) Pivotal may defer such amendment or
     supplement  for up to 120 days,  provided  that:  (a) Pivotal shall not use
     such right of deferral with respect to any registration  statement for more
     than an aggregate of 120 days in any 12-month period; and (b) the number of
     days Pivotal is required to keep the registration statement effective shall
     be  extended by the number of days for which  Pivotal  shall have used such
     right of deferral;

          (iii)  furnish  to each  Holder  of such  Registrable  Securities  one
     conformed copy of the registration statement and of each such amendment and
     supplement  thereto (in each case  including  all exhibits) and one of each
     document incorporated by reference therein and such number of copies of the
     prospectus  included in the registration  statement  (including any summary
     prospectus);




                                      -6-
<PAGE>

          (iv) use its best  efforts  to  register  or qualify  all  Registrable
     Securities and other securities covered by the registration statement under
     such securities or Blue Sky laws of the states of the United States as each
     Holder of such Registrable  Securities shall  reasonably  request,  to keep
     such   registration  or   qualification  in  effect  for  so  long  as  the
     registration  statement  remains in effect  (subject to the  limitations in
     Section  3(a)),  except  that  Pivotal  shall not for any such  purpose  be
     required to qualify  generally to do business as a foreign  corporation  in
     any jurisdiction in which it is not and would not, but for the requirements
     of this Section  3(c)(iv),  be obligated to be so qualified,  or to subject
     itself to  taxation  in any such  jurisdiction,  or to  consent  to general
     service of process in any such jurisdiction;

          (v) immediately  notify each Holder of Registrable  Securities covered
     by the registration  statement, at any time when a prospectus or prospectus
     supplement   relating  thereto  is  required  to  be  delivered  under  the
     Securities  Act, upon discovery that, or upon the happening of any event as
     a result of which, the prospectus  included in the registration  statement,
     as then in effect, includes an untrue statement of a material fact or omits
     to state any material  fact  required to be stated  therein or necessary to
     make  the   statements   therein  not   misleading  in  the  light  of  the
     circumstances  then existing  which untrue  statement or omission  requires
     amendment  of  the  registration   statement  or   supplementation  of  the
     prospectus,  and (subject to Section 3(a)(v) and Section  3(c)(ii)  hereof)
     promptly  thereafter prepare and furnish to such Holder a reasonable number
     of copies of a supplement  to or an amendment of such  prospectus as may be
     necessary  so that,  as  thereafter  delivered  to the  purchasers  of such
     Registrable   Securities  such  prospectus  shall  not  include  an  untrue
     statement of a material  fact or omit to state a material  fact required to
     be  stated  therein  or  necessary  to  make  the  statements  therein  not
     misleading  in the  light of the  circumstances  then  existing;  provided,
     however, that each Holder of Registrable  Securities registered pursuant to
     the  registration  statement  agrees  that  such  Holder  will not sell any
     Registrable  Securities  pursuant to the registration  statement during the
     time that Pivotal is preparing and filing with the  Commission a supplement
     to or an amendment of such prospectus or registration statement;

          (vi) otherwise use commercially  reasonable efforts to comply with all
     applicable rules and regulations of the Commission; and

          (vii)  provide  and  cause  to be  maintained  a  transfer  agent  and
     registrar  for  all  Registrable  Securities  covered  by the  registration
     statement  from and after a date not later than the  effective  date of the
     registration statement.

Each Holder of  Registrable  Securities  as to which any  registration  is being
effected shall furnish to Pivotal such information regarding such Holder and the
distribution  of such  Registrable  Securities  as Pivotal may from time to time
reasonably  request in  connection  therewith,  and if any holder fails to do so
within a reasonable time after Pivotal  requests such  information,  Pivotal may
exclude such Holder's Registrable Securities from such registration.

     (d) Indemnification.

          (i)  Indemnification  by Pivotal.  Pivotal  shall  indemnify  and hold
     harmless  each Holder  (including  the  trustee(s)  of any such  Holder) of
     Registrable  Securities  whose  securities are covered by the  registration
     statement  from and  against  any  demands,  claims,  actions  or causes of
     action, assessments, losses, damages, liabilities,  interest and penalties,
     costs and expenses  (including,  without limitation,  reasonable legal fees
     and  disbursements   incurred  in  connection   therewith  and  in  seeking
     indemnification  therefor,  and any amounts or expenses required to be paid
     or incurred in connection with any action, suit, proceeding, claim, appeal,
     demand,  assessment or judgment) (individually,  a "Loss" and, collectively
     "Losses"),  joint or several, to which such Holder may become subject under
     the Securities Act or otherwise  insofar as such Losses (or related actions
     or proceedings)  arise out of or are based upon (A) any untrue statement or
     alleged untrue statement of any material fact contained in the registration
     statement,   final  prospectus  or  summary  prospectus  contained  in  the
     registration  statement, or any amendment or supplement to the registration
     statement,  or any document  incorporated by reference in the  registration
     statement  or (B) any  omission  or  alleged  omission  to state  therein a
     material  fact  required  to be stated  therein  or  necessary  to make the
     statements therein not misleading;  provided,  however,  that Pivotal shall
     not be liable  in any such  case to the  extent  that any such  Losses  (or
     actions or proceedings  in respect  thereof) arise out of or are based upon
     an untrue  statement  or alleged  untrue  statement  or omission or alleged
     omission made in the registration  statement, or any such final prospectus,
     summary  prospectus,  amendment  or  supplement,  as the  case  may be,  in
     reliance  upon and in  conformity  with  written  information  furnished to
     Pivotal  by a  Holder  specifically  for  use in the  preparation  of  such
     registration  statement;  and provided  further,  that Pivotal shall not be
     liable in any such case to the extent that any such Losses  arise out of or
     are based upon an untrue  statement or alleged untrue statement or omission
     or alleged  omission in the final  prospectus,  if such untrue statement or
     alleged untrue statement or omission or alleged omission is corrected in an
     amendment or supplement to the final prospectus and such Holder  thereafter
     fails to deliver such final prospectus as so amended or supplemented  prior
     to or concurrently with the sale of the Registrable  Securities  covered by
     the  registration  statement  to the person  asserting  such  Losses  after
     Pivotal  had  furnished  such  Holder  with a  sufficient  number of copies
     thereof in a manner and at a time sufficient to permit delivery of the same
     by such Holder.

          (ii)  Indemnification by the Holders.  As a condition to including any
     Registrable  Securities in the registration  statement,  Pivotal shall have
     received an undertaking reasonably satisfactory to it from each prospective
     Holder  of such  Registrable  Securities,  severally  and not  jointly,  to
     indemnify  and hold  harmless (in the same manner and to the same extent as
     set forth in Section  3(d)(i)  hereof)  Pivotal,  each director of Pivotal,
     each officer of Pivotal who shall sign the registration  statement and each
     other person, if any, who controls Pivotal within the meaning of Section 15
     of the  Securities  Act or Section 20 of the  Exchange  Act, and each other
     Holder of Registrable  Securities  included in the  registration  statement
     with respect to any untrue statement in or omission from such  registration
     statement,   final  prospectus  or  summary  prospectus   included  in  the
     registration statement, or any amendment or supplement to the




                                      -8-
<PAGE>

     registration  statement,  as the case may be,  of a  material  fact if such
     statement  or omission  was made in reliance  upon and in  conformity  with
     information furnished to Pivotal by such Holder specifically for use in the
     preparation  of  the  registration  statement,  final  prospectus,  summary
     prospectus, amendment or supplement, as the case may be.

          (iii) Notice of Claims,  etc. In the event that any of the indemnified
     parties under Sections  3(d)(i) or 3(d)(ii) (each, an "Indemnified  Party")
     is made a defendant  in or party to any action or  proceeding,  judicial or
     administrative,  instituted  by any third  party for the  liability  or the
     costs or  expenses  of which are  Losses  (any such third  party  action or
     proceeding  being referred to as a "Claim"),  the  Indemnified  Party shall
     give the party hereto  obligated to indemnify such  Indemnified  Party (the
     "Indemnifying  Party")  prompt  notice  thereof.  The  failure to give such
     notice  shall  not  affect  any   Indemnified   Party's   ability  to  seek
     reimbursement unless such failure has materially and adversely affected the
     Indemnifying   Party's  ability  to  defend   successfully  a  Claim.   The
     Indemnifying  Party  shall be  entitled  to contest  and defend such Claim.
     Notice of the  intention  so to contest  and  defend  shall be given by the
     Indemnifying  Party to the Indemnified  Party within 20 business days after
     the Indemnified  Party's notice of such Claim (but, in all events, at least
     five business days prior to the date that an answer to such Claim is due to
     be filed).  Such  contest  and  defense  shall be  conducted  by  reputable
     attorneys  employed by the Indemnifying  Party. The Indemnified Party shall
     be entitled at any time, at its own cost and expense  (which  expense shall
     not constitute a Loss unless the Indemnified  Party  reasonably  determines
     that the  Indemnifying  Party,  because of a conflict of interest,  may not
     adequately  represent,   any  interests  of  the  Indemnified  Parties,  to
     participate  in such contest and defense and to be represented by attorneys
     of its or their own choosing,  provided that the  Indemnifying  Party shall
     not be required to bear the fees and expenses of counsel to all Indemnified
     Parties  in  any  one  action  or  any  action  arising  out  of  the  same
     registration  statement.  If the Indemnified Party elects to participate in
     such defense,  the Indemnified  Party will cooperate with the  Indemnifying
     Party in the conduct of such defense. Neither the Indemnified Party nor the
     Indemnifying Party may concede,  settle or compromise any Claim without the
     consent  of the  other  party,  which  consents  will  not be  unreasonably
     withheld.

          (iv) Contribution. If the indemnification provided for in this Section
     3(d) is unavailable or insufficient  to hold harmless an Indemnified  Party
     in respect of any Losses,  then each  Indemnifying  Party shall, in lieu of
     indemnifying  such  Indemnified  Party,  contribute  to the amount  paid or
     payable  by such  Indemnified  Party as a  result  of such  Losses  in such
     proportion as appropriate to reflect the relative fault of Pivotal,  on the
     one hand, and such Holder of Registrable Securities, on the other hand, and
     to the parties'  relative  intent,  knowledge,  access to  information  and
     opportunity  to correct or mitigate the damage in respect of or prevent any
     untrue   statement  or  omission   giving  rise  to  such   indemnification
     obligation. Pivotal and the Holders of Registrable Securities agree that it
     would not be just and equitable if  contributions  pursuant to this Section
     3(d)(iv)  were  determined by pro rata  allocation  (even if the Holders of
     Registrable  Securities  were treated as one entity for such purpose) or by
     any other method of allocation  which did not take account of the equitable
     considerations referred to above in this Section 3(d)(iv). No person guilty
     of fraudulent misrepresentation (within the




                                      -9-
<PAGE>

     meaning of  Section  11(f) of the  Securities  Act)  shall be  entitled  to
     contribution  from  any  person  who  is  not  guilty  of  such  fraudulent
     misrepresentation.

     (e) Registration Expenses. Pivotal shall bear all Registration Expenses.

     Section 4.  Termination.  The rights and  obligations  under this Agreement
(other than under Sections 3(d) and 3(e) hereof) shall  automatically  terminate
upon the earlier to occur of (a) the sale of all  Registrable  Securities by the
Holders  and (b) the date on which the  Registrable  Securities  shall have been
outstanding  for two years. No holder shall have the right to request to include
Registrable  Securities  in any  registration  statement if (a) the  Registrable
Securities are eligible for sale pursuant to Rule 144(k), or (b) the Registrable
Securities  are  eligible  for sale  pursuant  to Rule 144 and the  Holder  owns
Registrable  Securities  in the amount of less than 1% of Pivotal's  outstanding
Common Shares.

     Section  5.  Amendments  and  Waivers.  This  Agreement  may be  amended or
modified and Pivotal may take any action herein  prohibited,  or omit to perform
any act herein  required  to be  performed  by it,  only if  Pivotal  shall have
obtained the written consent to such amendment, modification, action or omission
to act,  of the holder or holders  (at such time) of a majority of the shares of
Registrable Securities (and, in the case of any amendment,  modification, action
or omission to act which  adversely  affects any specific  holder of Registrable
Securities or a specific group of holders of Registrable Securities, the written
consent  of each  such  holder  or  holders  of a  majority  of the  Registrable
Securities held by such group). Each holder of any Registrable Securities at the
time shall be bound by any consent  authorized by this Section 5, whether or not
such Registrable Securities shall have been marked to indicate such consent.

     Section 7. Notices.  All notices,  demands and other  communications  to be
given or delivered  under or by reason of the  provisions of this Agreement will
be in writing and will be deemed to have been given when personally delivered or
three days after being mailed by first class mail, return receipt requested,  or

transmission  device.  Notices,  demands and  communications  to Pivotal and the
