     thirty (30) calendar days after the Closing Date, the Reoffer  Registration
     Statement  with  respect  to the  offer and sale of the  Securities  by the

<PAGE>

     Company is acting in good faith to cause the Reoffer Registration Statement
     to be declared effective such date will be extended to 90 days after filing
     thereof.

(b)  The Company  shall use its best  efforts to keep the  Reoffer  Registration
     Statement  continuously effective in order to permit the Prospectus forming
     part  thereof  to be usable by  Holders  for a period of two years from the

     Commission.  The Company  shall be deemed not to have used its best efforts
     to keep the Reoffer  Registration  Statement effective during the requisite
     period if it  voluntarily  takes any action that would result in Holders of
     securities covered thereby not being able to offer and sell such securities
     during that period, unless (i) such action is required by applicable law or
     (ii)  such  action  is taken by the  Company  in good  faith  and for valid

     hereunder),  including,  without limitation, the acquisition or divestiture

     Reoffer  Registration  Statement  is not filed with the  Commission  or the
     Reoffer Registration Statement is not declared effective, in each instance,
     within the time  periods  prescribed  in Section  2(a) or (iii) the Reoffer
     Registration  Statement  ceases  to be  effective  so that  the  Prospectus
     contained  therein is not usable by the Holders for offers and sales of the
     Securities  during the time period prescribed in Section 2(b); or (iii) any
     of the  Securities  remain  Registrable  Securities  following  the Reoffer
     Registration  Period,  then if any  Holder  so  requests  with  respect  to
     Securities which remain Registrable Securities the following will apply:

         (a)      The Company shall as promptly as practicable  (but in no event
                  not  more  than 30  days  after  so  requested  by any  Holder
                  pursuant  to this  Section  3) file  with the  Commission  and
                  thereafter  shall use its best efforts to cause to be declared
                  effective  under the Act,  at the  election  of the  Holder so
                  requesting,   a  Demand  Registration  Statement  or  a  Shelf
                  Registration  Statement  relating to the offer and sale of the
                  Securities  or  any  other   Registrable   Securities  by  the
                  requesting Holder from time to time in accordance with the

                                            5

<PAGE>

                  methods of  distribution  elected by such Holder and set forth
                  in such Demand  Registration  Statement or Shelf  Registration
                  Statement;  provided,  that if permitted  under the Act and by
                  the  Commission,  the Company may file a pre or post effective
                  amendment or supplement to the Reoffer Registration  Statement
                  if such action would completely  fulfil its obligations  under
                  this Section 3.

(b)  The  Company  shall use its best  efforts  to keep the  Shelf  Registration
     Statement  continuously effective in order to permit the Prospectus forming
     part  thereof  to be usable by  Holders  for a period of two years from the
     date  the  Shelf  Registration  Statement  is  declared  effective  by  the
     Commission  or  such  shorter  period  that  will  terminate  when  all the
     Securities  or any  other  Registrable  Securities  covered  by  the  Shelf
     Registration  Statement  have been sold pursuant to the Shelf  Registration
     Statement  (in  any  such  case,   such  period  being  called  the  "Shelf
     Registration  Period").  The  Company  shall be deemed not to have used its
     best efforts to keep the Shelf Registration  Statement effective during the
     requisite  period if it  voluntarily  takes any action that would result in
     Holders of securities covered thereby not being able to offer and sell such
     securities  during  that  period,  unless (i) such  action is  required  by
     applicable  law or (ii) such  action is taken by the  Company in good faith
     and for valid business  reasons (not  including  avoidance of the Company's
     obligations hereunder),  including,  without limitation, the acquisition or
     divestiture of assets, so long as the Company promptly  thereafter complies
     with the requirements of Section 4(k) hereof, if applicable.

(c)  The  Company  shall use its best  efforts to keep the  Demand  Registration
     Statement  continuously effective in order to permit the Prospectus forming
     part thereof to be usable by Holders until all the  Securities or any other
     Registrable  Securities covered by the Demand  Registration  Statement have
     been sold pursuant to the Demand Registration  Statement (in any such case,
     such period being  called the "Demand  Registration  Period").  The Company
     shall  be  deemed  not to have  used its best  efforts  to keep the  Demand
     Registration   Statement  effective  during  the  requisite  period  if  it
     voluntarily  takes any action  that would  result in Holders of  securities
     covered thereby not being able to offer and sell

                                        6

<PAGE>

     such securities  during that period,  unless (i) such action is required by
     applicable  law or (ii) such  action is taken by the  Company in good faith
     and for valid business  reasons (not  including  avoidance of the Company's
     obligations hereunder),  including,  without limitation, the acquisition or
     divestiture of assets, so long as the Company promptly  thereafter complies
     with the requirements of Section 4(k) hereof, if applicable.

     under  which  they  were  made)  not  misleading  (which  advice  shall  be
     accompanied by an  instruction  to suspend the use of the Prospectus  until

     Company  may from time to time  reasonably  require for  inclusion  in such
     Registration   Statement  (and  shall  promptly   correct  any  information
     previously   furnished  if  the  inclusion  of  such  information  in  such
     Registration Statement would be materially misleading), and the Company may
     exclude from such Registration  Statement the Securities of any Holder that
     fails to furnish such information after receiving a request therefor.

(o)  The Company  shall,  if  requested,  promptly  incorporate  in a Prospectus
     supplement or post-effective  amendment to a Registration  Statement,  such
     information as the Managing  Underwriter,  if applicable,  and the Majority
     Holders  agree  should be  included  therein  and shall  make all  required
     filings of such Prospectus  supplement or post-effective  amendment as soon
     as notified of the matters to be incorporated in such Prospectus supplement
     or post-effective amendment.

(p)  In the case of any  Registration  Statement,  the Company  shall enter into
     such agreements and take all other appropriate actions in order to expedite
     or facilitate the registration or the disposition of the Securities, and in
     connection therewith,  if an underwriting  agreement is entered into, cause
     the same to  contain  indemnification  provisions  and  procedures  no less
     favourable  than  those  set  forth  in  Section  6 hereof  (or such  other
     provisions  and  procedures  acceptable  to the  Majority  Holders  and the
     Managing Underwriters, if any),

                         11

     with respect to all parties to be indemnified  pursuant to Section 6 hereof
     from Holders of Securities to the Company.

(q)  In the case of any Shelf  Registration  Statement  or  Demand  Registration
     Statement,  the Company shall (i) make reasonably  available for inspection
     by the Holders of securities to be registered  thereunder,  any underwriter

     such  underwriter  all  relevant  financial  and other  records,  pertinent
     corporate  documents and  properties  of the Company and its  subsidiaries;
     (ii) cause the  Company's  officers,  directors and employees to supply all
     relevant  information  reasonably  requested  by the  Holders  or any  such
     underwriter,  attorney,  accountant or other agent in  connection  with any

     examinations;  provided , however,  that any information that is designated
     in writing by the Company,  in good faith,  as  confidential at the time of
     delivery of such information  shall be kept  confidential by the Holders or
     any such  underwriter,  attorney,  accountant  or other agent,  unless such
     disclosure  is made in  connection  with a court  proceeding or required by
     law, or such  information  becomes  available  to the public  generally  or
     through   a   third   party   without   an   accompanying   obligation   of
     confidentiality;  (iii) make such  representations  and  warranties  to the
     Holders of securities registered  thereunder and the underwriters,  if any,
     in  form,  substance  and  scope  as are  customarily  made by  issuers  to
     underwriters  in primary  underwritten  offerings;  (iv) obtain opinions of
     counsel to the Company  (which  counsel and  opinions  (in form,  scope and
     substance) shall be reasonably  satisfactory to the Managing  Underwriters,

     each selling Holder and the underwriters,  if any, covering such matters as
     are customarily covered in opinions requested in underwritten offerings and
     such other  matters as may be  reasonably  requested  by such  Holders  and
     underwriters;  (v) obtain  "cold  comfort"  letters (or, in the case of any
     person that does not satisfy the conditions for receipt of a "cold comfort"

     procedures  letter")  and updates  thereof from the  independent  certified
     public accountants of the Company (and, if necessary, any other independent
     certified public accountants of

                                       12

<PAGE>

     any  subsidiary  of the Company or of any business  acquired by the Company
     for which  financial  statements and financial data are, or are required to
     be,  included in the  Registration  Statement),  addressed  to each selling
     Holder of securities registered thereunder and the underwriters, if any, in
     customary  form and  covering  matters of the type  customarily  covered in
     "cold comfort" letters in connection with primary  underwritten  offerings;
     and (vi) deliver  such  documents  and  certificates  as may be  reasonably
     requested by the Majority  Holders and the Managing  Underwriters,  if any,
     including  those to  evidence  compliance  with  Section  4(k) and with any
     customary  conditions  contained  in the  underwriting  agreement  or other
     agreement  entered into by the Company.  The foregoing actions set forth in
     clauses  (iii),  (iv), (v) and (vi) of this Section 4(q) shall be performed
     at  (A)  the  effective  date  of  such  Registration  Statement  and  each
     post-effective   amendment   thereto  and  (B)  each   closing   under  any
     underwriting or similar agreement as and to the extent required thereunder.

(r)  In the case of the Reoffer  Registration  Statement,  the Company shall (i)

     and other  records,  pertinent  corporate  documents and  properties of the
     Company and its subsidiaries;  (ii) cause the Company's officers, directors
     and employees to supply all relevant  information  reasonably  requested by
     such Holder or any such  attorney,  accountant or other agent in connection
     with the Reoffer  Registration  Statement as is  customary  for similar due
     diligence  examinations;  provided,  however,  that any information that is
     designated in writing by the Company, in good faith, as confidential at the
     time of delivery of such  information  shall be kept  confidential  by such
     Holder  or any such  attorney,  accountant  or  other  agent,  unless  such
     disclosure  is made in  connection  with a court  proceeding or required by
     law, or such  information  becomes  available  to the public  generally  or
     through   a   third   party   without   an   accompanying   obligation   of
     confidentiality;  (iii) make such  representations  and  warranties  to the
     Holders, in form, substance and scope as are customarily made by issuers to
     underwriters  in primary  underwritten  offerings;  (iv) obtain opinions of
     counsel to the Company,  which  counsel and  opinions  (in form,  scope and
     substance) shall be reasonably

                         13

<PAGE>

     satisfactory  to the Majority  Holders and their counsel,  addressed to all
     Holders,  covering  such  matters as are  customarily  covered in  opinions
     requested  in  underwritten  offerings  and such  other  matters  as may be
     reasonably  requested by the Majority Holders or their counsel;  (v) obtain

     business  acquired  by the  Company  for  which  financial  statements  and
     financial  data are, or are  required to be,  included in the  Registration
     Statement),  addressed  to the  Holders,  in  customary  form and  covering
     matters  of the type  customarily  covered  in "cold  comfort"  letters  in
     connection  with  primary  underwritten  offerings,  or if requested by the
     Majority  Holders or their counsel in lieu of a "cold comfort"  letter,  an

     covering matters  requested by the Majority  Holders or their counsel;  and
     (vi) deliver such documents and certificates as may be reasonably requested
     by the  Majority  Holders or their  counsel,  including  those to  evidence

     (iv),  (v),  and  (vi) of this  Section  4(r)  shall  be  performed  at the
     effective date of the Reoffer Registration Statement and the effective date
     of any post-effective amendment to the Reoffer Registration Statement.

5.   Registration  Expenses.  The Company  shall bear all  expenses  incurred in
     connection with the performance of its obligations  under Sections 2, 3 and
     4 hereof and, in the event of the Reoffer  Registration  Statement  and any
     Shelf  Registration  Statement  or  Demand  Registration  Statement,   will
     reimburse the Holders for the reasonable fees and disbursements of one firm
     or counsel (in addition to one local counsel in each relevant jurisdiction)
     designated  by the  Majority  Holders  to act as  counsel  for  Holders  in
     connection therewith ("Holders' Counsel") up to $20,000.

6.   Indemnification and Contribution.

(a)  In connection with any  Registration  Statement,  the Company,  jointly and
     severally,  agree to indemnify  and hold harmless each Holder of securities
     covered thereby, the directors, officers, employees and agents of each such
     Holder and each other person, if any, who

                          14

<PAGE>

(1)  controls  any such  Holder  within  the  meaning  of  Section 15 the Act or
     Section 20 of the Exchange Act against any and all losses,  claims, damages
     or liabilities,  joint or several,  to which they or any of them may become
     subject under the Act, the Exchange Act or other federal or state statutory
     law or  regulation,  at common law or  otherwise,  insofar as such  losses,
     claims, damages or liabilities (or actions in respect thereof) arise out of
     or are based upon any untrue  statement  or alleged  untrue  statement of a
     material fact contained in the  Registration  Statement as originally filed
     or  in  any  amendment  thereof,  or  in  any  preliminary   Prospectus  or
     Prospectus, or in any amendment thereof or supplement thereto, or arise out
     of or are based upon the  omission or alleged  omission to state  therein a
     material  fact  required  to be stated  therein  or  necessary  to make the
     statements  therein  not  misleading,  and  agrees to  reimburse  each such
     indemnified party, as incurred,  for any legal or other expenses reasonably
     incurred by them in  connection  with  investigating  or defending any such
     loss, claim, damage, liability or action;  provided,  however, that (i) the
     Company  will not be liable in any case to the  extent  that any such loss,
     claim,  damage or liability  arises out of or is based upon any such untrue
     statement or alleged untrue  statement or omission or alleged omission made
     therein  in  reliance  upon  and in  conformity  with  written  information
     furnished  to the Company by or on behalf of any such  Holder  specifically
     for  inclusion  therein  and (ii) the  Company  shall  not be liable to any
     indemnified  party  under  this  indemnity  agreement  with  respect to the
     Registration  Statement  or  Prospectus  to the extent  that any such loss,
     claim, damage or liability of such indemnified party results solely from an
     untrue  statement  of a material  fact  contained  in, or the omission of a
     material fact from, the  Registration  Statement or Prospectus which untrue
     statement  or  omission  was  corrected  in  an  amended  or   supplemented
     Registration  Statement or  Prospectus,  if the person  alleging such loss,
     claim,  damage  or  liability  was not  sent or  given,  at or prior to the
     written  confirmation  of such sale, a copy of the amended or  supplemented
     Registration   Statement  or  Prospectus  if  the  Company  had  previously
     furnished  copies  thereof to such  indemnified  party and if delivery of a
     prospectus  is  required  by the Act and was not so  made.  This  indemnity
     agreement  will be in  addition  to any  liability  which the  Company  may
     otherwise have.

                                   15

<PAGE>

(b)  Each Holder of securities covered by a Registration Statement severally but
     not jointly agrees to indemnify and hold harmless (i) the Company (ii) each
     of the Company's directors,  (iii) each of the Company's officers who signs
     such  Registration  Statement  and (iv)  each  other  person,  if any,  who
     controls the Company within the meaning of Section 15 of the Act or Section
     20 of the Exchange Act to the same extent as the foregoing  indemnity  from
     the  Company  to each such  Holder,  but only  with  reference  to  written
     information  relating  to such  Holder  furnished  to the  Company by or on
     behalf of such Holder  specifically for inclusion in the documents referred
     to in the foregoing indemnity. This indemnity agreement will be in addition
     to any liability which any such Holder may otherwise have.

(c)  Promptly  after  receipt by an  indemnified  party under this  Section 6 of
     notice of the commencement of any action, such indemnified party will, if a
     claim in respect thereof is to be made against the indemnifying party under
     this  Section  6,  notify  the   indemnifying   party  in  writing  of  the
     commencement  thereof;  but the failure so to notify the indemnifying party
     (i) will not relieve it from  liability  under  paragraph  (a) or (b) above
     unless and to the extent it did not otherwise learn of such action and such
     failure results in the forfeiture by the indemnifying  party of substantial
     rights  and  defences  and  (ii)  will  not,  in  any  event,  relieve  the
     indemnifying party from any obligations to any indemnified party other than
     the indemnification  obligation provided in paragraph (a) or (b) above. The
     indemnifying  party  shall be  entitled  to appoint as counsel  one firm of
     attorneys of the indemnifying  party's choice at the  indemnifying  party's
     expense,   which   counsel,   together  with  one  local  counsel  in  each
     jurisdiction,  shall act on behalf of all the  indemnified  parties  in any
     action for which indemnification is sought (in which case the indemni-fying
     party shall not thereafter be responsible  for the fees and expenses of any
     separate counsel  retained by the  indem-nified  party or parties except as
     set forth below); provided,  however, that such counsel shall be reasonably
     satisfactory to the indemnified  party.  Notwithstanding  the  indemnifying
     party's  election to appoint counsel to represent the indemnified  party in
     an action,  the  indemnified  party shall have the right to employ separate
     counsel  (including local counsel),  and the indemnifying  party shall bear
     the reasonable fees, costs and expenses of such separate

                                      16

<PAGE>

     counsel  (and  local  counsel)  if (i) the  use of  counsel  chosen  by the
     indemnifying  party to represent the  indemnified  party would present such
     counsel  with  a  conflict  of  interest,  (ii)  the  actual  or  potential
     defendants in, or targets of, any such action include both the  indemnified
     party and the  indemnifying  party and the  indemnified  party  shall  have
     reasonably  concluded  that  there may be legal  defences  available  to it
     and/or other indemnified  parties which are different from or additional to
     those available to the indemnifying  party,  (iii) the  indemnifying  party
     shall not have employed counsel reasonably  satisfactory to the indemnified
     party to represent  the  indemnified  party within a reasonable  time after
     notice of the  institution  of such action or (iv) the  indemnifying  party
     shall  authorize the indemnified  party to employ  separate  counsel at the
     expense of the  indemnifying  party. No indemnifying  party shall be liable
     for any settlement of any such action effected  without its written consent
     (which consent shall not be unreasonably withheld), but if settled with its
     written  consent or if there be a final  judgment for the  plaintiff in any
     such action,  the indemnifying  party agrees to indemnify and hold harmless
     any  indemnified  party from and against any loss or liability by reason of
     such settlement or judgment.  An indemnifying  party will not,  without the
     prior written consent of the indemnified  parties,  settle or compromise or
     consent  to the  entry of any  judgment  with  respect  to any  pending  or
     threatened  claim,   action,   suit  or  proceeding  in  respect  of  which
     indemnification or contribution may be sought hereunder (whether or not the
     indemnified  parties  are  actual or  potential  parties  to such  claim or
     action)  unless  such   settlement,   compromise  or  consent  includes  an
     unconditional  release of each indemnified party from all liability arising
     out of such claim, action, suit or proceeding.

(d)  In the event that the  indemnity  provided in paragraph  (a) or (b) of this
     Section 6 is unavailable to or insufficient to hold harmless an indemnified
     party for any reason,  then each applicable  indemnifying party, in lieu of
     indemnifying  such  indemnified  party,  shall  have a  joint  and  several
     obligation  to  contribute to the  aggregate  losses,  claims,  damages and
     liabilities  (including  legal or other  expenses  reasonably  incurred  in
     connection with investigating or defending same) (collectively "Losses") to
     which  such  indemnified  party may be  subject  in such  proportion  as is
     appropriate to reflect the relative benefits received

                                       17

<PAGE>

(1)  by such indemnifying party, on the one hand, and such indemnified party, on
     the other hand, from the Initial  Placement and the Registration  Statement
     which resulted in such Losses; provided, however, that in no case shall any
     Purchaser or any subsequent  Holder of any Security be responsible,  in the
     aggregate,  for any amount in excess of the purchase discount or commission
     applicable  to such  Security  as set forth on the cover  page of the Final
     Memorandum,  nor shall any  underwriter  be  responsible  for any amount in
     excess  of  the  underwriting  discount  or  commission  applicable  to the
     securities  purchased by such underwriter under the Registration  Statement
     which  resulted  in  such  Losses.  If  the  allocation   provided  by  the
     immediately   preceding   sentence  is  unavailable  for  any  reason,  the
     indemnifying  party and the  indemnified  party  shall  contribute  in such
     proportion as is appropriate to reflect not only such relative benefits but
     also the relative fault of such  indemnifying  party,  on the one hand, and
     such  indemnified  party,  on  the  other  hand,  in  connection  with  the
     statements or omissions  which resulted in such Losses as well as any other
     relevant equitable  considerations.  Benefits received by the Company shall
     be deemed to be equal to the total net proceeds from the Initial  Placement
     (before  deducting  expenses)  as set forth on the cover  page of the Final
     Memorandum.  Benefits  received  by BGs  shall be deemed to be equal to the
     total purchase  discounts and commissions as set forth on the cover page of
     the Final  Memorandum,  and benefits received by any other Holders shall be
     deemed to be equal to the value of receiving  Securities  registered  under
     the Act.  Benefits  received by any underwriter shall be deemed to be equal
     to the total  underwriting  discounts and commissions,  as set forth on the
     cover page of the Prospectus  forming a part of the Registration  Statement
     which  resulted  in such  Losses.  Relative  fault shall be  determined  by
     reference to whether any alleged  untrue  statement or omission  relates to
     information  provided by the indemnifying party, on the one hand, or by the
     indemnified  party,  on the other hand. The parties agree that it would not
     be  just  and  equitable  if  contribution  were  determined  by  pro  rata
     allocation or any other method of allocation which does not take account of
     the  equitable  considerations  referred  to  above.   Notwithstanding  the
     provisions  of  this   paragraph   (d),  no  person  guilty  of  fraudulent
     misrepresentation (within the meaning of Section 11(f) of the Act) shall be
     entitled to

                                     18

<PAGE>

(1)  contribution  from  any  person  who was  not  guilty  of  such  fraudulent
     misrepresentation. For purposes of this Section 6, each person who controls
     a Holder  within the meaning of either the Act or the Exchange Act and each
     director,  officer,  employee  and agent of such Holder shall have the same
     rights to  contribution  as such  Holder,  and each person who controls the
     Company  within the  meaning of either the Act or the  Exchange  Act,  each
     officer of the Company who shall have signed the Registration Statement and
     each director of the Company shall have the same rights to  contribution as
     the Company, subject in each case to the applicable terms and conditions of
     this paragraph (d).

(e)  The  provisions  of this  Section 6 will  remain in full force and  effect,
     regardless  of any  investigation  made by or on behalf of any Holder,  the
     Company or any of the officers,  directors or controlling  persons referred
     to in Section 6 hereof, and will survive the sale by a Holder of securities
     covered by a Registration Statement.

7.   Miscellaneous.

(a)  No  Inconsistent  Agreements.  The Company has not, as of the date  hereof,
     entered into,  nor shall it, on or after the date hereof,  enter into,  any
     agreement  with respect to its  securities  that is  inconsistent  with the
     rights  granted  to the  Holders  herein or  otherwise  conflicts  with the
     provisions hereof.

(b)  Amendments  and Waivers.  The provisions of this  Agreement,  including the
     provisions of this  sentence,  may not be amended,  qualified,  modified or
     supplemented,  and waivers or consents to  departures  from the  provisions
     hereof may not be given,  unless  the  Company  has  obtained  the  written
     consent  of the  Holders  of at least a  majority  of the then  outstanding
     Securities;  provide  that,  with  respect to any matter  that  directly or
     indirectly  affects the rights of any Holder  hereunder,  the Company shall
     obtain  the  written  consent  of  each  such  Holder  against  which  such
     amendment, qualification, supplement, waiver or consent is to be effective.
     Notwithstanding the foregoing (except the foregoing  proviso),  a waiver or
     consent to departure  from the  provisions  hereof with respect to a matter
     that relates  exclusively  to the rights of Holders  whose  securities  are
     being sold pursuant to a

                                             19

<PAGE>

     Registration  Statement and that does not directly or indirectly affect the
     rights of other Holders may be given by the Majority Holders, determined on
     the basis of  securities  being  sold  rather  than  registered  under such
     Registration Statement.

(c)  Notices.  All notices and other  communications  provided  for or permitted
     hereunder shall be made in writing by hand-delivery,  first-class mail, fax
     or air courier guaranteeing overnight delivery:

(1)  if to a Holder,  at the most  current  address  given by such holder to the
     Company in  accordance  with the  provisions  of this Section  7(c),  which
     address  initially  is, with  respect to each  Holder,  the address of such
     Holder maintained by the Company's registrar, with a copy in like manner to
     Beeson Gregory Limited;

(2)  if to BG,  initially at the  respective  addresses set forth in the Placing
     Agreement; and

(3)  if to the  Company,  initially  at its  address  set  forth in the  Placing

     All such  notices  and  communications  shall be have been duly  given when
     received.  BGs  or  the  Company  by  notice  to the  other  may  designate
     additional or different addresses for subsequent notices or communications.

(d)  Successors and Assigns. This Agreement shall inure to the benefit of and be
     binding upon the successors and assigns of each of the parties,  including,
     without  the need for an express  assignment  or any consent by the Company
     thereto,  subsequent Holders of Securities.  The Company each hereby agrees
     to extend the benefits of this  Agreement to any Holder of  Securities  and
     any such Holder may  specifically  enforce the provisions of this Agreement
     as if an original party hereto.

(e)  Counterparts.  This agreement may be executed in any number of counterparts
     and by the parties hereto in separate  counterparts,  each of which when so
     executed  shall be deemed to be an original and all of which taken together
     shall constitute one and the same agreement.

                            20

<PAGE>

(f)  Headings.  The headings in this agreement are for  convenience of reference
     only and shall not limit or otherwise affect the meaning hereof.

(g)  Governing  Law.  This  agreement  shall be  governed  by and  construed  in
     accordance  with the internal laws of the State of New York (without regard
     to the conflict of law provisions thereof).

(h)  Severability. In the event that any one or more of the provisions contained
     herein, or the application  thereof in any circumstances.  is held invalid,
     illegal or  unenforceable  in any  respect for any  reason,  the  validity,
     legality and  enforceability  of any such  provision in every other respect
     and of the remaining  provisions hereof shall not be in any way impaired or
     affected  thereby,  it being intended that all of the rights and privileges
     of the parties shall be enforceable to the fullest extent permitted by law.

(i)  Securities  Held by the Company.  etc.  Whenever the consent or approval of
     Holders of a specified  percentage  of  Securities  is required  hereunder,
     Securities,  as applicable,  held by the Company or its  Affiliates  (other
     than subsequent  Holders of Securities if such subsequent Holder are deemed
     to be  Affiliates  solely by reason of their  holdings of such  Securities)
     shall not be counted in  determining  whether  such consent or approval was
     given by the Holders of such required percentage.

(j)  Further Assurances.  Each party shall cooperate and take such action as may
     be  reasonably  requested  by  another  party in  order  to  carry  out the
     provisions and purposes of this Agreement and the transactions contemplated
     hereby.

(k)  Remedies.  In the event of a breach or a threatened  breach by any party to
     this Agreement of its obligations  under this Agreement,  any party injured
     or to be injured by such breach,  in addition to being entitled to exercise
     all rights granted by law, including recovery of damages,  will be entitled
     to specific performance of its rights under this Agreement, it being agreed
     by the parties  that the remedy at law,  including  monetary  damages,  for

(l)  Company Repurchase.  In the event that the Company fails to comply with any
     provision  of this  Agreement,  the Company  shall within 30 days after the
     date on which the Company  was  required to take any action or if such date
     is undeterminable,  the date of the receipt by the Company of a demand from
     any Holder (in either case, the "Initial Date"),  purchase from each Holder
     all Registrable  Securities  held by each respective  Holder for a purchase
     price (the "Purchase Price") equal to the product of (a) the average Market
     Value Per Share during the period  beginning on the Initial Date and ending
     on the date of payment of the Purchase  Price  multiplied by (b) the number
     of Registrable  Securities held by such Holder.  The Company shall also pay
     all reasonable costs (including all tranfer taxes,  stamp duty or SDRT) and
     fees associated with such purchase by the Company.  Payment of the Purchase
     Price shall be in immediately available funds. Each Holder may, in its sole
     discretion,  waive  its  right,  in whole or in part,  to have the  Company
     repurchase the Registrable  Securities held by him and retain the ownership
     of such Registrable Securities.  "Market Value Per Share" at any date shall
     be (i) the highest  reported  sale price on that date with  respect to each
     type of security in question listed on an international securities exchange
     or admitted  to  unlisted  trading  privileges  on such an exchange  or, if
     applicable,  (ii) the highest reported sale price on that date with respect
     to each type of security in question quoted on the National  Association of
     Securities  Dealers Automated  Quotations System ("NASDAQ") or the European
     Association of Securities Dealers Automated Quotation System ("EASDAQ") or,
     if  applicable,  (iii) if no such sale is made on such day, the mean of the
     closing bid and asked  prices for such day on such  exchange or reported by
     NASDAQ or EASDAQ.

THIS AGREEMENT is made on                                      January 2000
--------------                                             ---
BETWEEN:-

(1)  AUTHORISZOR  INC. a company  incorporated  and  registered  in the State of
     Delaware,  USA and whose  registered  office is at Suite 600,  8201 Preston
     Road, Dallas Texas TX 75225, USA ("Company");

(2)  BEESON  GREGORY  LIMITED a company  registered  in  England  and Wales with
     registered number 2316630 whose registered office is at The Registry, Royal
     Mint Court, London EC3N 4LB ("Beeson Gregory"); and

(3)  those persons whose names and addresses are set out in the schedule to this
     agreement ("Directors").

RECITALS

A.   At the date of this agreement, the Company has authorised 30,000,000 shares
     of common stock par value US0.01 each  ("Shares")  and 2,000,000  shares of
     preferred  stock par value US$0.01 each of which shares of common stock are
     in issue and a further  shares of common  stock are  subject to options and
     warrants issued by the Company.

B.   The  Company  proposes  to issue  ___________  new  Shares  under a placing
     ("Placing")  to be made by  Beeson  Gregory  on behalf  of the  Company  to
     institutional and other investors outside the USA.

C.   The  Company  and Beeson  Gregory  (as  financial  adviser to the  Company)
     believe, and each of the Directors acknowledge that, because of the size of
     their respective  shareholdings and/or their relationship with the Company,
     it is in the best  interests of the Company and of protecting the market in
     the Shares that the  Directors  refrain  from  disposing of Shares owned by
     them or by persons  connected with them for a period  following the date of
     this agreement.

NOW IT IS HEREBY AGREED as follows:-

1.       LOCK-UP

         below),  it will not,  without  the  prior  written  consent  of Beeson
         Gregory,  transfer or otherwise  dispose of any Shares in which he or a
         person  connected  with  him  is  directly  or  indirectly   interested

<PAGE>

         (including  those Shares the subject of options or warrants in which he
         or a person connected with him is directly or indirectly interested) on

         direct or indirect  interest in such  shares,  receipts or  securities)
         ("Relevant  Securities")  during the period from and including the date
         of this agreement  until the date six months  thereafter  ("Restriction
         Period");  provided  that any Director  shall be entitled to dispose or
         procure the disposal of Shares in which he or a person  connected  with
         him is directly or  indirectly  interested  to the extent  necessary to
         meet any claim made by Beeson  Gregory  against such Director under the
         terms of the placing agreement of even date and relating to the Placing
