     2.   Registration Rights under the Securities Act.

          (a) Demand Registration Rights.

               (i) At anytime after the Effective  Time, upon receipt by MDSI of
          a written request therefor from the Shareholder delivered on or before
          the  first   anniversary  of  the  Effective   Time,  MDSI  shall  use
          commercially   reasonable   efforts  to  prepare  and  file  with  the
          Commission  as soon as  practicable  (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, the choice of which such form shall
          be in MDSI's sole discretion,  (or, in MDSI 's sole discretion, on any
          appropriate  form under the Securities Act as may then be available to
          MDSI )  relating  to the resale of up to twenty  percent  (20%) of the
          Registrable  Securities  held by the  Shareholder  as of the Effective
          Time,  such  number of  Registrable  Securities  to be  reduced by the
          number of MDSI  Common  Shares  sold by the  Shareholder  prior to the
          effective date of such registration  statement) in accordance with the
          methods  of  distribution  set  forth in such  registration  statement
          (which  shall not  include,  without the consent of MDSI (which may be
          granted  or  withheld  in  MDSI '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) MDSI shall be  obligated  to  prepare,  file and cause to be
          effective  only  one (1)  Shelf  Registration  Statement  pursuant  to
          Section 2(a)(i).

               (iii) MDSI agrees to use commercially  reasonable efforts to keep
          the Shelf  Registration  Statement  continuously  effective for ninety
          (90)  days  or  until  the   distribution   described   in  the  Shelf
          Registration  Statement  has  been  completed,   whichever  period  is
          shorter,  provided  that the period  for which the Shelf  Registration
          Statement  is to 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 2(a)(iv) hereof.

               (iv) Without  limiting the provisions of Section  2(a)(iii),  the
          Shareholder  agrees,  if so requested by MDSI, not to effect any offer
          or sale of MDSI 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 MDSI  or any  underwriter  in  connection  with  any
          registered offering of MDSI Common Shares; provided however, that such
          period shall not be in excess of 180 days after the effective  date of
          such  registration   statement  or  such  shorter  period  as  may  be
          applicable to directors and executive officers at MDSI with respect to
          such offering or (y) by MDSI in  connection  with any proposal or plan
          by MDSI to engage in any material financing or material acquisition or
          disposition by MDSI or any subsidiary  thereof of the capital stock or
          substantially  all the assets of 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 MDSI and its subsidiaries taken as
          a whole;  provided,  however,  that any such  period  shall  not be in
          excess of 120 days.  Any period  within the  Effective  Period  during
          which MDSI fails to keep the Shelf  Registration  Statement  effective
          and usable for resales of MDSI Common Shares,  or requires pursuant to
          this Section  2(a)(iv) that the  Shareholder  not effect sales of MDSI
          Common  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 MDSI to
          the  Shareholder  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 MDSI Shares or, in the
          case of a  suspension  pursuant  to this  Section  2(a)(iv)  the  date
          specified in the notice delivered by MDSI

                                       2
<PAGE>

          pursuant to this Section 2(a)(iv), and shall end on the date when each
          Shareholder  covered  by  the  Shelf  Registration   Statement  either
          receives  the  copies  of  the  supplemented  or  amended   prospectus
          contemplated by Section 2(c)(ii) or is advised in writing by MDSI that
          use  of the  prospectus  or  sales  may be  resumed.  The  undersigned
          Shareholder  also  agrees  that (i) in the event that any  Registrable
          Securities  held by the Shareholder are registered by MDSI pursuant to
          this Agreement,  the Shareholder  will not effect any offer or sale of
          MDSI  Common  Shares,  except  pursuant to an  effective  registration
          statement  filed pursuant to Section 2(a) or (b) hereof,  prior to the
          twelve month  anniversary  of the Effective  Time and (ii) at any time
          such  Shareholder  is an employee,  consultant  or a director of MDSI,
          such  Shareholder  will be subject to and comply with the  policies of
          MDSI  regarding  purchases  and sales of MDSI Common  Shares copies of
          which have been provided to the  Shareholder  in connection  with this
          Agreement.  The  Shareholder  acknowledges  that  such  policy  may be
          changed by MDSI from time to time.

          (b) Piggyback Registration Rights.

               (i) Each time MDSI 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 cash
          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),  MDSI  will  give  written  notice  of  their
          determination  to the  Shareholder.  Upon the  written  request of the
          Shareholder given within thirty (30) days after the date of mailing of
          any such notice from MDSI, MDSI will, except as herein provided, cause
          up to twenty percent (20%) of the  Registrable  Securities held by the
          Shareholder  (less  the  number  of  MDSI  Common  Shares  sold by the
          Shareholder pursuant to any registration statement),  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 Shareholder to be so registered;  provided,  however, that nothing
          herein shall prevent MDSI from, at any time,  with or without  notice,
          abandoning or delaying any registration.

               (ii)  If any  registration  pursuant  to  this  Section  2(b)  is
          underwritten   in  whole  or  in  part,  MDSI  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 MDSI or  interfere  with the  successful  marketing  of the
          shares  offered by MDSI,  the number of  Registrable  Securities to be
          included in the  Offering may be reduced pro rata among the holders of
          all   Registrable   Securities   proposed   to  be   included  in  the
          registration,  in the proportion that the number of MDSI Common Shares
          held by each holder  proposing  to include  MDSI Common  Shares in the
          registration statement bears to the total number of common shares held
          by all such holders.  MDSI does hereby  represent that,  other than as
          provided in this Agreement,  there are no holders of shares of capital
          stock of MDSI that have any  registration  rights superior to those of
          the Registrable  Securities.  MDSI hereby  covenants that it shall not
          grant any person registration rights with respect to shares of capital
          stock  of  MDSI  that  are  superior  to the  rights  of  the  Holders
          hereunder.

          (c) Registration  Procedures.  If and whenever MDSI is required by the
     provisions  of  Sections  2(a)  and  2(b) to  effect  the  registration  of
     Registrable Securities under the Securities Act, MDSI will use commercially
     reasonable  efforts to effect the registration and sale of such Registrable
     Securities in accordance with such reasonable methods of disposition as may
     be specified in writing by the Shareholder  participating therein.  Without
     limiting the foregoing, MDSI 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

                                       3
<PAGE>

          required  to be stated  therein or  necessary  to make the  statements
          therein  in  the  light  of  all  the  facts  and   circumstances  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 Shareholder or shareholders  thereof set
          forth in the registration statement (which shall not include,  without
          the  consent of MDSI  (which may be granted or withheld in MDSI's sole
          discretion)  an  underwritten   offering)  or  a  date  calculated  as
          described in Section 2(a)(iii)  hereof;  provided that if the Board of
          Directors  of  MDSI  in its  judgment  determines  that  amending  the
          registration  statement or supplementing  the prospectus would require
          disclosure of information at a time that would be detrimental to MDSI,
          then  notwithstanding  this  Section  2(c)(ii)  MDSI  may  defer  such
          amendment or supplement  for up to 120 days,  provided  that: (a) MDSI
          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  MDSI is  required  to keep  the
          registration  statement  effective  shall be extended by the number of
          days for which MDSI shall have used such right of deferral;

               (iii)  furnish  to the  Shareholder  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);

               (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  Shareholder  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  2(a)),  except that MDSI 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  2(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  the  Shareholder,  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  2(a)(iv) and Section  2(c)(ii)  hereof)  promptly
          thereafter prepare and furnish to such Shareholder 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 facts and  circumstances
          then existing;  provided,  however,  that the Shareholder  agrees that
          such Shareholder will not sell any Registrable  Securities pursuant to
          the registration  statement during the time that MDSI 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

                                       4
<PAGE>

               (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 and cause all such Registrable  Securities
          to be listed on such national  securities exchange or automated system
          on which the class of Registrable Securities is then listed.

         The Shareholder  shall furnish to MDSI such information  regarding such
         Shareholder and the distribution of such Registrable Securities as MDSI
         may from time to time reasonably request in connection  therewith,  and
         if the  Shareholder  fails to do so within a reasonable time after MDSI
         requests  such  information,   MDSI  may  exclude  such   Shareholder's
         Registrable Securities from such registration.

          (d) Transfer of Registration  Rights.  The rights of Shareholder under
     this Agreement may not be transferred except (i) to a transferee who is the
     heir of Shareholder, the personal representative of Shareholder's estate or
     a revocable trust voluntarily established by such Shareholder primarily for
     his benefit,  and (ii) by  Shareholder  to any Affiliate of  Shareholder to
     which any of the shares owned by  Shareholder  are  transferred;  provided,
     however,  that (x) MDSI is given written notice by such  Shareholder at the
     time of such  assignment  and transfer  stating the name and address of the
     transferee and  identifying the securities with respect to which the rights
     under  this  Agreement  are being  assigned  and  transferred,  and (y) the
     transferee  executes  such  documents  as MDSI may request  evidencing  the
     transferee's agreement to be bound by the restrictions herein.

          (e) General  Indemnification.  In connection with any  registration or
     qualification  of the Registrable  Securities under this Agreement (i) MDSI
     shall  indemnify  and hold  harmless  the  Shareholder,  including  but not
     limited to each person or entity,  if any,  who  controls  the  Shareholder
     within the meaning of Section 15 of the Securities Act, against all losses,
     claims,  damages,  liabilities  and expenses  (including but not limited to
     reasonable  expenses  incurred in  investigating,  preparing  and defending
     against any claim) to which the Shareholder or such controlling  person may
     become  subject  under the  Securities  Act, the Exchange Act or otherwise,
     insofar  as the same  arise out of or are based  upon or are  caused by any
     untrue  statement or alleged untrue  statement of a material fact contained
     in any registration  statement or prospectus (as amended or supplemented if
     MDSI shall have furnished any amendments or supplements  thereto) furnished
     pursuant  to this  Agreement  or insofar as the same arise out of are based
     upon or are caused by any omission or alleged  omission to state  therein a
     material  fact  require  to be  stated  therein  or  necessary  to make the
     statement  therein not misleading,  except insofar as such losses,  claims,
     damages,  liabilities or expenses are ultimately  determined to have arisen
     out of or were based upon or were caused by any untrue statement or alleged
     untrue  statement  or  omission  or alleged  omission  based  upon  written
     information  furnished to MDSI by or on behalf of  Shareholder  or any such
     control  person for inclusion in any  registration  statement or prospectus
     (and any amendments or supplements thereto);  provided,  however, that MDSI
     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  Shareholder  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 MDSI had  furnished  such  Shareholder  with a
     sufficient number of copies thereof in a manner and at a time sufficient to
     permit delivery of the same by such Shareholder, and (ii) Shareholder shall
     indemnify  MDSI,  its  affiliates,  any person who signed any  registration
     statement,  and their  respective  officers,  directors and control persons
     against  all  such  losses,  claims,  damages,   liabilities  and  expenses
     (including   but  not   limited  to   reasonable   expenses   incurred   in
     investigating,  preparing and defending  against any claim)  insofar as the
     same  arise  out of or are  based  upon or are  caused  by any such  untrue
     statement  or alleged  untrue  statement  or any such  omission  or alleged
     omission based on written information  furnished to MDSI by or on behalf of
     such  Shareholder  or any such  control  person  for the  inclusion  in any
     registration  statement or prospectus  (and any  amendments or  supplements
     thereto).

          (f)  Notice  of,  and  Procedures  for,  Collecting   Indemnification.
     Promptly upon receipt by a party indemnified under this Agreement of notice
     of the commencement of any action against such indemnified party in respect
     of which indemnity or reimbursement may be sought against any indemnifying

                                       5
<PAGE>

     party  under  this  Agreement,  such  indemnified  party  shall  notify the
     indemnifying  party in writing of the commencement of such action,  but the
     failure to so notify the  indemnifying  party  shall not  relieve it of any
     liability which it may have to any  indemnified  party otherwise than under
     this Agreement  unless such failure shall  materially and adversely  affect
     the  defense of such  action.  In case notice of  commencement  of any such
     action  shall be given to the  indemnifying  party as above  provided,  the
     indemnifying  party shall be entitled to  participate in and, to the extent
     it may wish, jointly with any other indemnifying party similarly  notified,
     to assume  the  defense of such  action at its own  expense,  with  counsel
     chosen by it and reasonably  satisfactory to such  indemnified  party.  The
     indemnified  party shall have the right to employ separate legal counsel in
     any such action and  participate in the defense  thereof,  but the fees and
     expenses  of such  counsel  (other  than  reasonable  expenses  incurred in
     investigating,  preparing and defending against any claim) shall be paid by
     the indemnified  party unless (a) the indemnifying  party agrees to pay the
     same, (b) the indemnifying party fails to assume the defense of such action
     with counsel reasonably satisfactory to the indemnified party (in such case
     the  indemnifying  party  shall not have the right to assume the defense of
     such action on behalf of such indemnified  party), or (c) the named parties
     to any such action  (including any impleaded  parties) have been advised by
     such  counsel  that  representation  of  such  indemnified  party  and  the
     indemnifying  party  by the  same  counsel  would  be  inappropriate  under
     applicable   standards   of   professional   conduct  (in  which  case  the
     indemnifying  party  shall not have the right to assume the defense of such
     action on behalf of such  indemnified  party).  In the event that either of
     the  circumstances  described  in  clauses  (b)  and  (c) of  the  sentence
     immediately  preceding shall occur,  the  indemnified  party shall have the
     right to select a separate  counsel  and to assume  such legal  defense and
     otherwise  to  participate  in the  defense  of any such  action,  with the
     expenses and fees of such separate  counsel and other  expenses  related to
     such  participation to be reimbursed by the indemnifying party as incurred.
     No indemnifying  party shall be liable for any settlement entered into with
     its consent, which consent shall not be unreasonably withheld or delayed.

     3. Agreement to Vote Shares.  At every meeting of the  shareholders  of the
Company  called,  and at  every  adjournment  thereof,  and on every  action  or
approval by written consent of the shareholders of the Company,  the undersigned
Shareholder  (in his or her capacity as such) shall cause the Shares to be voted
in favor of approval of the Reorganization Agreement and the Merger; in favor of
each of the other transactions  contemplated by the Reorganization Agreement; in
favor of any matter that could  reasonably be expected to facilitate the Merger;
and against any matter that is inconsistent with the prompt  consummation of the
Merger and other transactions contemplated by the Reorganization Agreement.

     4. Irrevocable  Proxy.  Concurrently  with the execution of this Agreement,
Shareholder  agrees to execute and deliver to MDSI a proxy in the form  attached
hereto as Exhibit A (the  "Proxy"),  which shall be  irrevocable  to the fullest
extent permissible by law, with respect to the Shares.

     5.  Representations  and Warranties of the Shareholder.  Shareholder (a) is
the sole beneficial owner of the Shares and the options and warrants to purchase
Shares  indicated  on the final  page of this  Agreement,  free and clear of any
liens,  claims,  options,  rights of first refusal (except as may be held by the
Company), co-sale rights, charges or other encumbrances;  and (b) has full power
and authority to make,  enter into and carry out the terms of this Agreement and
the Proxy.

     6.  Additional  Documents.  Shareholder  (in his or her  capacity  as such)
hereby  covenants  and agrees to execute and deliver  any  additional  documents
necessary or  desirable,  in the  reasonable  opinion of MDSI,  to carry out the
intent of this Agreement.

     7.  Consent and Waiver.  Shareholder  (not in his capacity as a director or
officer of the Company) hereby gives any consents or waivers that are reasonably
required for the consummation of the Merger under the terms of any agreements to
which Shareholder is a party or pursuant to any rights Shareholder may have.

     8. Legending of Shares.  If so requested by MDSI,  Shareholder  agrees that
the Shares shall bear a legend  stating that they are subject to this  Agreement
and to an  irrevocable  proxy.  Shareholder  agrees that  Shareholder  shall not
Transfer the Shares  without first having the  aforementioned  legend affixed to
the certificates representing the Shares.

     9. Miscellaneous.

          (a) Severability.  If any term, provision,  covenant or restriction of
     this Agreement is held by a court of competent  jurisdiction to be invalid,
     void  or  unenforceable,  then  the  remainder  of the  terms,  provisions,
     covenants and restrictions of this Agreement shall remain in full force and
     effect and shall in no way be affected, impaired or invalidated.

          (b)  Binding  Effect and  Assignment.  This  Agreement  and all of the
     provisions  hereof  shall be binding  upon and inure to the  benefit of the
     parties hereto and their respective  successors and permitted assigns, but,
     except as otherwise  specifically  provided herein,  neither this Agreement
     nor any of the rights,  interests or  obligations of the parties hereto may
     be assigned by either of the parties  without prior written  consent of the
     other.

          (c) Amendments and  Modification.  This Agreement may not be modified,
     amended,  altered or supplemented except upon the execution and delivery of
     a written agreement executed by the parties hereto.

          (d)  Waiver.  No  waiver,  alteration  or  modification  of any of the
     provisions of this Agreement  shall be binding unless in writing and signed
     by the parties  hereto.  No failure or delay by any party in executing  any
     right,  power or privilege  hereunder shall operate as a waiver hereof, nor
     shall any single or partial  exercise  hereof  preclude any other or future
     exercise  hereof or the  exercise of any other  right,  power or  privilege
     hereof.

          (e)  Specific  Performance;  Injunctive  Relief.  The  parties  hereto
     acknowledge  that MDSI shall be irreparably  harmed and that there shall be
     no  adequate  remedy  at law for a  violation  of any of the  covenants  or
     agreements of Shareholder set forth herein.  Therefore,  it is agreed that,
     in addition to any other  remedies  that may be  available to MDSI upon any
     such  violation,  MDSI shall have the right to enforce such  covenants  and
     agreements by specific performance, injunctive relief or by any other means
     available to MDSI at law or in equity.

          (f)  Notices.  All notices and other  communications  pursuant to this
     Agreement shall be in writing and deemed to be sufficient if contained in a
     written  instrument  and  shall be  deemed  given  to a party if  delivered
     personally,  telecopied, sent by nationally recognized overnight courier or

                                IRREVOCABLE PROXY

     The  undersigned   Shareholder  of  Connectria   Corporation,   a  Missouri
corporation (the "Company"), hereby irrevocably (to the fullest extent permitted
by law) appoints Kenneth Miller, Robert Cruickshank and Glenn Kumoi, and each of

full power of substitution and  resubstitution,  to vote and exercise all voting
and related  rights (to the full extent that the  undersigned  is entitled to do
so) with  respect to all of the shares of capital  stock of the Company that now
are or hereafter may be beneficially  owned by the undersigned,  and any and all
other shares or securities of the Company issued or issuable in respect  thereof
on or after the date hereof (collectively,  the "Shares") in accordance with the
terms  of  this  Proxy.  The  Shares   beneficially  owned  by  the  undersigned
Shareholder  of the Company as of the date of this Proxy are listed on the final
page of this Proxy. Upon the undersigned's  execution of this Proxy, any and all
prior  proxies  given by the  undersigned  with respect to any Shares are hereby
revoked and the  undersigned  agrees not to grant any  subsequent  proxies  with
respect to the Shares until after the Expiration Date (as defined below).

     This Proxy is  irrevocable  (to the fullest  extent  permitted  by Missouri
law), is coupled with an interest and is granted pursuant to that certain Voting

Company,  and certain Principal  Shareholders of the Company. The Reorganization
Agreement  provides  for the merger of Merger  Sub with and into the  Company in
accordance with its terms (the "Merger").  As used herein,  the term "Expiration
Date"  shall  mean  the  earlier  to  occur  of (i)  such  date  and time as the
Reorganization  Agreement shall have been validly terminated pursuant to Section
8 thereof or (ii) such date and time as the Merger  shall  become  effective  in
accordance  with the  terms  and  provisions  of the  Reorganization  Agreement.
Capitalized terms not defined herein shall have the meanings ascribed to them in
the Reorganization Agreement.

     The  attorneys  and  proxies  named  above,  and each of them,  are  hereby
authorized and empowered by the undersigned, at any time prior to the Expiration
Date, to act as the undersigned's  attorney and proxy to vote the Shares, and to
exercise all voting,  consent and similar rights of the undersigned with respect
to the Shares (including,  without limitation,  the power to execute and deliver
written consents) at every annual,  special or adjourned meeting of Shareholders
of the Company and in every written  consent in lieu of such meeting in favor of
approval of the Reorganization Agreement and the Merger, in favor of each of the
other transactions contemplated by the Reorganization Agreement, in favor of any
matter that could  reasonably be expected to  facilitate  the Merger and against
any matter that is  inconsistent  with the prompt  consummation of the Merger or
other transactions contemplated by the Reorganization Agreement.

     The  attorneys  and proxies  named above may not exercise this Proxy on any
other matter except as provided above. The undersigned  Shareholder may vote the
Shares on all other matters.

     Any  obligation  of the  undersigned  hereunder  shall be binding  upon the
successors and assigns of the undersigned.

     This Proxy is irrevocable (to the fullest extent permitted by Missouri law)
as it is coupled  with an  interest.  This Proxy shall  terminate,  and be of no
further force and effect, automatically upon the Expiration Date.

                  REPRESENTATIONS AND WARRANTIES OF INVESTOR

The Investor represents and warrants to the Company that:

      Section 3.1. Intent. The Investor is entering into this Agreement for its
own account, and the Investor has no view to the distribution of the Registrable
Securities, the Convertible Notes or the Warrants and has no present arrangement
(whether or not legally binding) at any time to sell, assign, transfer, pledge,
encumber, hypothecate or otherwise dispose of the Registrable Securities, the
Convertible Notes or the Warrants to or through any person or entity; provided,
however, that by making the representations herein, the Investor does not agree
to hold the Registrable Securities, the Convertible Notes or the Warrants for
any minimum or other specific term and reserves the right to dispose of the
Registrable Securities, the Convertible Notes or the Warrants at any time
pursuant to the Registration Statement and in accordance with federal and state
securities laws applicable to such disposition.

      Section 3.2. Sophisticated Investor. The Investor is a sophisticated
investor (as described in Rule 506(b)(2)(ii) of Regulation D) and an accredited
investor (as defined in Rule 501 of Regulation D), and the Investor has such
experience in business and financial matters that it is capable of evaluating
the merits and risks of an investment in the Common Stock and the Convertible
Notes. The Investor acknowledges that an investment in the Common Stock and the
Convertible Note is speculative and involves a high degree of risk.

      Section 3.3. Authority. Each of this Agreement and the Registration Rights
Agreement has been duly authorized by all necessary corporate action, and no
further consent or authorization of the Investor, or its Board of Directors or
stockholders is required. Each of this Agreement and the Registration Rights
Agreement was validly executed and delivered by the Investor and each is a valid
and binding agreement of the Investor enforceable against it in accordance with
its terms, subject to applicable bankruptcy, insolvency, or similar laws
relating to, or affecting generally the enforcement of, creditors' rights and
remedies or by other equitable principles of general application.

      Section 3.4. Not an Affiliate. The Investor is not an officer, director or
"affiliate" (as that term is defined in Rule 405 of the Securities Act) of the
Company.

      Section 3.5. Organization and Standing. Investor is duly organized,
validly existing, and in good standing under the laws of Bermuda.

      Section 3.6. Absence of Conflicts. The execution and delivery of this
Agreement and any other document or instrument contemplated hereby, and the
consummation of the transactions contemplated thereby, and compliance with the
requirements thereof, will not (a) violate any law, rule, regulation, order,
writ, judgment, injunction, decree or award binding on Investor, or, to the
Investor's knowledge, (b) violate any provision of any indenture, instrument or
agreement to which Investor is a party or is subject, or by which Investor or
any of its assets is bound, (c) conflict with or constitute a material default
thereunder, (d) result in the creation or imposition of any lien pursuant to the
terms of any such indenture, instrument or agreement, or constitute a breach of
any fiduciary duty owed by Investor to any third party, or (e) require the
approval of any third-party (that has not been obtained) pursuant to any
material contract to which Investor is subject or to which any of its assets,
operations or management may be subject.

      Section 3.7. Disclosure; Access to Information. Investor has received or
had access to all documents, records, books and other information pertaining to
Investor's investment in the Company that have been requested by Investor. The
Investor has received and reviewed copies of the SEC Documents.

      Section 3.8. Manner of Sale. At no time was Investor presented with or
solicited by or through any leaflet, public promotional meeting, television
advertisement or any other form of general solicitation or advertising.

      Section 3.9. Resale Restrictions. Investor acknowledges that any
Registrable Securities, the Convertible Notes and Warrants to be acquired by
Investor have not been registered under the federal securities laws or any
applicable state securities laws in reliance upon exemptions available for
non-public or limited offerings. Investor understands that it must bear the
economic risk of the investment in the Registrable Securities, the Convertible
Notes and Warrants because the Registrable Securities, the Convertible Notes and
Warrants have not been so registered and therefore are subject to restrictions
upon transfer such that they may not be sold or otherwise transferred unless
registered under the applicable securities laws or an exemption from such
registration is available. The Investor will not reoffer, sell, assign,
transfer, pledge, encumber, hypothecate or otherwise dispose of any Registrable
Securities, the Convertible Notes or Warrants in the absence of an effective
registration statement, qualification or authorization relating thereto under
federal and applicable state securities laws or an opinion of qualified counsel
satisfactory to the Company to the effect that the proposed transaction in the
Registrable Securities, the Convertible Notes or Warrants will neither
constitute or result in any violation of the federal or state securities laws.
Subject to Section 8.1 of this Agreement, any certificate or other document that
may be issued representing any shares of Registrable Securities, the Convertible
Notes or Warrants may be endorsed with a legend to this effect.

      Section 3.10. Short Sales. In the thirty (30) Trading Days preceding the
Subscription Date, the Investor has not directly or indirectly engaged in any
Short Sale of the Common Stock.

ledgers and other similar records of the Company and the subsidiaries as made
available to Investor prior to the execution of this Agreement accurately

obligations convertible into or exchangeable for or giving any right to
subscribe for any shares of capital stock of the Company. All of the outstanding
shares of Common Stock of the Company have been duly and validly authorized and
issued and are fully paid and nonassessable.

      Section 4.6. Registration and Listing of Common Stock. The Company has

this Agreement by the Company and the consummation by the Company of the
transactions contemplated hereby, including without limitation the issuance of
the Put Shares, the Convertible Notes, the Note Conversion Shares, the Warrants
and the Warrant Shares do not and will not (i) result in a violation of the
Articles or By-Laws or (ii) conflict with, or constitute a material default (or
an event that with notice or lapse of time or both would become a default)

cancellation of, any material agreement, indenture, instrument or any "lock-up"
or similar provision of any underwriting or similar agreement to which the

stated therein or necessary to make the statements therein not misleading, and
that in the case of the related prospectus, it will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; (v) the declaration by
the SEC of the effectiveness of a Registration Statement; and (vi) the Company's
reasonable determination that a post-effective amendment to the Registration
Statement would be appropriate, and the Company shall promptly make available to
the Investor any such supplement or amendment to the related prospectus. The
Company shall not deliver to the Investor any Put Notice during the continuation
of any of the foregoing events. While in possession of material non-public
information received from the Company, the Investor shall not dispose of any
Registrable Securities until such information is disclosed to the public (a
"Restricted Period"); provided that, if such Restricted Period exceeds one
hundred twenty (120) days, the liquidated damages described in Section 1.1(c) of
the Registration Rights Agreement shall be increased to three percent (3.0%)
until such Restricted Period shall have elapsed.

      Section 6.9. Consolidation; Merger. The Company shall not, at any time
after the date hereof, effect any merger or consolidation of the Company with or
into, or a transfer of all or substantially all of the assets of the Company to,
another entity unless the resulting successor or acquiring entity (if not the
Company) assumes by written instrument the obligation to deliver to the Investor
such shares of stock and/or securities as the Investor is entitled to receive
pursuant to this Agreement and the Warrants.

      Section 6.10. Issuance of Put Shares, Note Conversion Shares, Warrant
Shares and Additional Shares. The sale of the Put Shares, the issuance of the
Convertible Notes, the issuance of the Warrant Shares pursuant to exercise of
the Warrants, and the issuance of Note Conversion Shares upon conversion of the
Convertible Notes shall be made in accordance with the provisions and
requirements of Regulation D and any applicable state law. Issuance of the
Warrant Shares pursuant to exercise of the Warrants through a cashless exercise
shall be made in accordance with the provisions and requirements of Section
3(a)(9) under the Securities Act and any applicable state law.

      Section 6.11. Legal Opinions on Subscription Date. The Company's
independent Nevada counsel shall deliver to the Investor on the Subscription
Date an opinion in the form of Exhibit E-1 hereto. The Company's special New
York counsel shall deliver to the Investor on the Subscription Date an opinion
in the form of Exhibit E-2 hereto.

      Section 6.12. No Similar Arrangement; Right of First Refusal. The Company
shall refrain from entering into any other agreements, arrangements or
understandings granting to the Company the right to sell shares of its
securities to one or more investors in placements exempt from registration under
the Securities Act until thirty (30) calendar days after this Agreement is
terminated pursuant to Section 2.5 hereof (the "Exclusivity Period"). If the
Company, for the purpose of obtaining any additional financing, wishes to sell
shares of its securities in placements exempt from registration under the
Securities Act during the Exclusivity Period (a "Sale") to a party other than a
Strategic Investor and other than the Investor (the "Third Party"), the Company
shall first offer (the "Offer") to the Investor, in writing, the right to
purchase such shares (the "Offered Shares") at the bona fide price offered by
the Third Party (the "Offer Price"). The Offer shall grant the Investor the
right during the five (5) Trading Days immediately following the date of the
Offer to elect to purchase any or all of the Offered Shares. The Company, in
connection with such a Sale, shall refrain from circumventing or attempting to
circumvent the Investor's right of first refusal by way of making such a Sale to
any of its Affiliates without first making an Offer to the Investor. If the
Investor so exercises its right to purchase any or all of the Offered Shares,
the purchase will be treated as a Put except that the purchase price for the
Offered Shares shall be the Offer Price. The closing and method of payment shall
be as provided for in Section 2.3 hereof and the Closing Date shall be seven (7)
Trading Days after the Investor exercises such right. If the Investor fails to
exercise its right to purchase any or all of the Offered Shares, then during the
sixty (60) calendar days immediately following the expiration of such right, the
Company shall be free to sell any or all of the Offered Shares to a purchaser
for a purchase price not lower than the Offer Price payable on terms and
conditions that are not more favorable to such purchaser than those contained in
the Offer. In the event that the Company effects a Sale to a Third Party, the
Investor may immediately terminate this Agreement. Notwithstanding the
foregoing, the Company shall be permitted to issue shares of its securities in
connection with an acquisition of another entity or assets related to the
Company's current or future business.

      Section 6.13. Confidential Information. The Company will hold, and will
use its best efforts to cause its Affiliates, and each of their respective
Representatives to hold, in strict confidence from any Person (other than any
such Affiliate or Representative), unless (i) compelled to disclose by judicial
or administrative process (including without limitation in connection with
obtaining the necessary approvals of this Agreement and the transactions
contemplated hereby of governmental or regulatory authorities) or by other
requirements of law or (ii) disclosed in an action or proceeding brought by a
party hereto in pursuit of its rights or in the exercise of its remedies
hereunder, all documents and information concerning the other party or any of
its Affiliates furnished to it by the other party or such other party's
Representatives in connection with this Agreement or the transactions
contemplated hereby, except to the extent that such documents or information can
be shown to have been (a) previously known by the party receiving such documents
or information, (b) in the public domain (either prior to or after the
furnishing of such documents or information hereunder) through no fault of such
receiving party or (c) later acquired by the receiving party from another source
if the receiving party is not aware that such source is under an obligation to
another party hereto to keep such documents and information confidential.

      Section 6.14. Public Announcements At all times at or before the Closing,
the Company, its Representatives and legal advisors, and the Investor will not
issue or make any reports, statements or releases to the public or to any third
party with respect to this Agreement or the transactions contemplated hereby
without the consent of both the Company and the Investor, which consent shall
not be unreasonably withheld. The Company, its Representatives and legal
advisors, and the Investor will also obtain both the Company's and the
Investor's prior approval of any press release to be issued announcing the
consummation of the transactions contemplated by this Agreement or in any way
referring to the other party or Affiliates of the other party. If either party
is unable to obtain the approval of its public report, statement, or press or
other release from the other party and such report, statement, or press or other
release is, in the opinion of legal counsel to such party, required by
applicable law in order to discharge such party's disclosure obligations, then
such party may make or issue the legally required report, statement, or press or
other release and promptly furnish the other party with a copy thereof.

      Section 6.15. Acquisition of Xtal Fibras Opticas, S.A. The Company shall
use commercially reasonable efforts to ensure that by July 31, 2000 the
acquisition by the Company or its Subsidiary of 90% of the issued and
outstanding capital stock of Xtal Fibras Opticas S.A. from Algar S.A. will be
consummated, and by such date, all necessary consents, authorizations and
approvals pertaining thereto will be obtained by the Company.

      Section 6.16. Berliner Bank Credit Facilities. The Company shall at no
time borrow any funds under, or otherwise make use of, (i) the Letter of Credit
(Kreditvertrag) dated November 13, 1996 between FiberCore Glasfaser Jena GmbH,
currently FiberCore Jena GmbH, and Berliner Bank, AG , or (ii) the Loan
Agreement (Darlehenvertrag) dated September 6, 1996 between the Company and
Berliner Bank AG.

                                  ARTICLE VII

                            CONDITIONS TO DELIVERY OF
                          PUT NOTICES AND CONDITIONS TO
                   INITIAL CLOSING AND SUBSEQUENT CLOSINGS

      Section 7.1. Conditions Precedent to the Obligation of the Company to
Issue and Sell Common Stock. The obligation hereunder of the Company to issue
and sell the Put Shares to the Investor incident to each Closing is subject to
the satisfaction, at or before each such Closing, of each of the conditions set
forth below.

            (a) Accuracy of the Investor's Representation and Warranties. The
representations and warranties of the Investor shall be true and correct in all
material respects as of the date of this Agreement and as of the date of each
such Closing as though made at each such time.

            (b) Performance by the Investor. The Investor shall have performed,
satisfied and complied in all respects with all covenants, agreements and
conditions required by this Agreement to be performed, satisfied or complied
with by the Investor at or prior to such Closing.

      Section 7.2. Conditions Precedent to the Right of the Company to Deliver a
Put Notice and the Obligation of the Investor to Purchase Convertible Notes and
Put Shares. The obligation of the Investor to pay for the Convertible Notes, the
right of the Company to deliver a Put Notice and the obligation of the Investor
hereunder to acquire and pay for the Put Shares incident to a Closing is subject
to the satisfaction, on (i) the Subscription Date, (ii) the applicable Put Date
and (iii) the applicable Closing Date (each, a "Condition Satisfaction Date"),
of each of the following conditions; provided, however, that with respect to the
initial Closing occurring on the Subscription Date only, the Investor waives the
conditions set forth in paragraphs (a), (b) and (l) of this Section 7.2:

            (a) Registration of the Registrable Securities with the SEC. As set
forth in the Registration Rights Agreement, the Company shall have filed with
the SEC a Registration Statement covering the resale of Registrable Securities
relating to the Early Put and Note Conversion Shares that shall have been
declared effective by the SEC in no event later than ninety (90) days after the
Subscription Date, and a Registration Statement covering the resale of
Registrable Securities relating to all subsequent Puts that shall have been
declared effective by the SEC prior to any subsequent Put.

            (b) Effective Registration Statement. As set forth in the
Registration Rights Agreement, the Registration Statement(s) shall have
previously become effective and shall remain effective on each Condition
Satisfaction Date and (i) neither the Company nor the Investor shall have
received notice that the SEC has issued or intends to issue a stop order with
respect to a Registration Statement or that the SEC otherwise has suspended or
withdrawn the effectiveness of a Registration Statement, either temporarily or
permanently, or intends or has threatened to do so (unless the SEC's concerns
have been addressed and the Investor is reasonably satisfied that the SEC no
longer is considering or intends to take such action), (ii) no other suspension
of the use or withdrawal of the effectiveness of such Registration Statement or
related prospectus shall exist, and (iii) with respect to the second Put only,
the Company shall have notified the Investor in accordance with Section 6.8
hereof that the Registration Statement covering the Registrable Securities
relating to the Early Put and Note Conversion Shares has been declared effective
by the SEC, and (iv) at least twenty-two (22) Trading Days shall have elapsed
since the Initial Registration Statement (as defined in the Registration Rights
Agreement) has been declared effective by the SEC.

            (c) Accuracy of the Company's Representations and Warranties. The
representations and warranties of the Company shall be true and correct as of
each Condition Satisfaction Date as though made at each such time (except for
representations and warranties specifically made as of a particular date).

            (d) Performance by the Company. The Company shall have performed,
satisfied and complied in all respects with all covenants, agreements and
conditions required by this Agreement, the Registration Rights Agreement, the
Convertible Notes and the Warrants to be performed, satisfied or complied with
by the Company at or prior to each Condition Satisfaction Date.

            (e) No Injunction. No statute, rule, regulation, executive order,
decree, ruling or injunction shall have been enacted, entered, promulgated or
adopted by any court or governmental authority of competent jurisdiction that
prohibits the transactions contemplated by this Agreement or otherwise has a
Material Adverse Effect, and no actions, suits or proceedings shall be in
progress, pending or threatened by any Person, that seek to enjoin or prohibit
the transactions contemplated by this Agreement or otherwise could reasonably be
expected to have a Material Adverse Effect. For purposes of this paragraph (e),
no proceeding shall be deemed pending or threatened unless one of the parties
has received written or oral notification thereof prior to the applicable
Closing Date.

            (f) No Suspension of Trading in or Delisting of Common Stock. The
trading of the Common Stock shall not have been suspended by the SEC, the
Principal Market or the NASD and the Common Stock shall have been approved for
listing or quotation on and shall not have been delisted from the Principal
Market. The issuance of shares of Common Stock with respect to the applicable
Closing, if any, shall not violate the shareholder approval requirements of the
Principal Market.

            (g) Legal Opinions. The Company shall have caused to be delivered to
the Investor, within five (5) Trading Days of the effective date of a
Registration Statement, an opinions of the Company's special New York counsel in
the forms of Exhibit E-2 and Exhibit E-3 hereto, addressed to the Investor.

            (h) Due Diligence. No dispute between the Company and the Investor
shall exist pursuant to Section 7.3 as to the adequacy of the disclosure
contained in the Registration Statement.

            (i) Ten Percent Limitation. On each Closing Date, the number of Put
Shares then to be purchased by the Investor shall not exceed the number of such
shares that, when aggregated with all other shares of Common Stock and
Registrable Securities then owned by the Investor beneficially or deemed
beneficially owned by the Investor, as determined in accordance with the
definition of beneficial ownership in Rule 13d-3 promulgated under the Exchange
Act, would result in the Investor owning more than 9.9% of all of such Common
Stock as would be outstanding on such Closing Date. For purposes of this
Section, in the event that the amount of Common Stock outstanding as determined
in accordance with Section 13(d) of the Exchange Act and the regulations
promulgated thereunder is greater on a Closing Date than on the date upon which
the Put Notice associated with such Closing Date is given, the amount of Common
Stock outstanding on such Closing Date shall govern for purposes of determining
whether the Investor, when aggregating all purchases of Common Stock made
pursuant to this Agreement and, if any, Incentive Warrant Shares would own more
than 9.9% of the Common Stock following such Closing Date.

            (j) [INTENTIONALLY OMITTED].

            (k) No Knowledge. The Company shall have no knowledge of any event
more likely than not to have the effect of causing any Registration Statement to
be suspended or otherwise ineffective (which event is more likely than not to
occur within the fifteen Trading Days following the Trading Day on which such
notice is deemed delivered).

            (l) Minimum Time Interval. The Minimum Time Interval shall have
elapsed since the immediately preceding Put Date.

            (m) Shareholder Vote. The issuance of shares of Common Stock and the
Convertible Notes with respect to the applicable Closing, if any, shall not
violate the shareholder approval requirements of the Principal Market. Following
each Put Notice, the Company shall promptly provide the Investor with a written
schedule stating as of such applicable Put Date (i) the total number of shares
of Outstanding Common Stock, (ii) the number of Put Shares issuable with respect
to the applicable Closing, (iii) the number of Early Put Shares issued, (iv) the
number of Early Put Warrant Shares issued, if any, (v) the number of Incentive
Warrant Shares issued, if any, (vi) the number of Note Conversion Shares issued,
if any, and (vii) the number of Note Conversion Shares issuable, calculated
based upon the conversion price on such Put Date as set forth in Section 3.1 of
each of the Convertible Notes. If the issuance by the Company of a number of
shares of Common Stock equal to the sum of the amounts stated in clauses (ii)
through (vii), inclusive, hereof would result in a violation by the Company of
the shareholder approval requirements of the Principal Market, the applicable
Put Notice shall be deemed null and void.

            (n) Other. On each Condition Satisfaction Date, the Investor shall
have received and been reasonably satisfied with such other certificates and
documents as shall have been reasonably requested by the Investor in order for
the Investor to confirm the Company's satisfaction of the conditions set forth
in this Section 7.2, including, without limitation, a certificate in
substantially the form and substance of Exhibit F hereto, executed in either
case by an executive officer of the Company and to the effect that all the
conditions to such Closing shall have been satisfied as at the date of each such
certificate; provided, however, that such certificate shall not be required to
be delivered with respect to the initial Closing occurring on the Subscription
Date.

      Section 7.3. Due Diligence Review; Non-Disclosure of Non-Public
Information.

            (a) The Company shall make available for inspection and review by
the Investor, advisors to and representatives of the Investor (who may or may
not be affiliated with the Investor and who are reasonably acceptable to the
Company), and any Underwriter, any Registration Statement or amendment or
supplement thereto or any blue sky, NASD or other filing, all financial and
other records, all SEC Documents and other filings with the SEC, and all other
corporate documents and properties of the Company as may be reasonably necessary
for the purpose of such review, and cause the Company's officers, directors and
employees to supply all such information reasonably requested by the Investor or
any such representative, advisor or Underwriter in connection with such
Registration Statement (including, without limitation, in response to all
questions and other inquiries reasonably made or submitted by any of them),
prior to and from time to time after the filing and effectiveness of such
Registration Statement for the sole purpose of enabling the Investor and such
representatives, advisors and Underwriters and their respective accountants and
attorneys to conduct initial and ongoing due diligence with respect to the
Company and the accuracy of such Registration Statement.

            (b) None of the Company, its officers, directors, employees and
agents shall in any event disclose material non-public information to the
Investor, advisors to or representatives of the Investor unless prior to
disclosure of such information the Company identifies such information as being
material non-public information and provides the Investor, such advisors and
representatives with the opportunity to accept or refuse to accept such
non-public information for review. The Company may, as a condition to disclosing
any non-public information hereunder, require the Investor's advisors and
representatives to enter into a confidentiality agreement in form reasonably
satisfactory to the Company and the Investor.

            (c) Nothing herein shall require the Company to disclose non-public
information to the Investor or its advisors or representatives, and the Company
represents that it does not disseminate material non-public information to any
investors who purchase stock in the Company in a public offering, to money
managers or to securities analysts; provided, however, that notwithstanding
anything herein to the contrary, the Company shall, as hereinabove provided,
immediately notify the advisors and representatives of the Investor and any
Underwriters of any event or the existence of any circumstance (without any
obligation to disclose the specific event or circumstance) of which it becomes
aware, constituting non-public information (whether or not requested of the
Company specifically or generally during the course of due diligence by such
persons or entities), which, if not disclosed in the prospectus included in the
applicable Registration Statement would cause such prospectus to include a
material misstatement or to omit a material fact required to be stated therein
in order to make the statements, therein, in light of the circumstances in which
they were made, not misleading. Nothing contained in this Section 7.3 shall be
construed to mean that such persons or entities other than the Investor (without
the written consent of the Investor prior to disclosure of such information) may
not obtain non-public information in the course of conducting due diligence in
accordance with the terms and conditions of this Agreement and nothing herein
shall prevent any such persons or entities from notifying the Company of their
opinion that based on such due diligence by such persons or entities, that such
Registration Statement contains an untrue statement of a material fact or omits
a material fact required to be stated in such Registration Statement or
necessary to make the statements contained therein, in light of the
circumstances in which they were made, not misleading.

                                  ARTICLE VIII

                                     LEGENDS

      Section 8.1. Legends. Each of the Warrants, the Convertible Notes and,
unless otherwise provided below, each certificate representing Registrable
Securities will bear the following legend (the "Legend"):

      "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
      OR ANY OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE
      UPON AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT
      AND SUCH OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR
      PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED,
      PLEDGED, ENCUMBERED, HYPOTHECATED OR OTHERWISE DISPOSED OF, EXCEPT
      PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT
      OR PURSUANT TO A TRANSACTION THAT IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH
      REGISTRATION. THE HOLDER OF THIS CERTIFICATE IS THE BENEFICIARY OF CERTAIN
      OBLIGATIONS OF THE COMPANY SET FORTH IN A SECURITIES PURCHASE AGREEMENT,
      DATED AS OF JUNE 9, 2000, BETWEEN FIBERCORE, INC. AND CRESCENT
      INTERNATIONAL LTD. A COPY OF THE PORTION OF THE AFORESAID AGREEMENT
      EVIDENCING SUCH OBLIGATIONS MAY BE OBTAINED FROM FIBERCORE, INC.'S
      EXECUTIVE OFFICES."

      On the Subscription Date, the Company shall issue to the transfer agent
for its Common Stock (and to any substitute or replacement transfer agent for
its Common Stock upon the Company's appointment of any such substitute or
replacement transfer agent) instructions in substantially the form of Exhibit G
hereto, with a copy to the Investor. Other than as required as a result of
change in law, such instructions shall be irrevocable by the Company from and
after the date hereof or from and after the issuance thereof to any such
substitute or replacement transfer agent, as the case may be, except as
otherwise expressly provided in the Registration Rights Agreement. It is the
intent and purpose of such instructions, as provided therein, to require the
transfer agent for the Common Stock from time to time upon transfer of
Registrable Securities by the Investor to issue certificates evidencing such
Registrable Securities free of the Legend during the following periods and under
the following circumstances and without consultation by the transfer agent with
the Company or its counsel and without the need for any further advice or
instruction or documentation to the transfer agent by or from the Company or its
counsel or the Investor:

            (a) At any time after the applicable Effective Date, upon surrender
of one or more certificates evidencing Common Stock that bear the Legend, to the
extent accompanied by a notice requesting the issuance of new certificates free
of the Legend to replace those surrendered; provided that (i) the applicable
Registration Statement shall then be effective and (ii) if reasonably requested
by the transfer agent, the Investor confirms to the transfer agent that the
Investor has transferred the Registrable Securities pursuant to such
Registration Statement and has complied with the prospectus delivery
requirement.

            (b) At any time upon any surrender of one or more certificates
evidencing Registrable Securities that bear the Legend, to the extent
accompanied by a notice requesting the issuance of new certificates free of the
Legend to replace those surrendered and containing representations that the
Investor is permitted to dispose of such Registrable Securities without
limitation as to amount or manner of sale pursuant to Rule 144 under the
Securities Act.

      Section 8.2. No Other Legend or Stock Transfer Restrictions. No legend
other than the one specified in Section 8.1 has been or shall be placed on the
share certificates representing the Common Stock, and no instructions or "stop
transfer orders," so called, "stock transfer restrictions," or other
restrictions have been or shall be given to the Company's transfer agent with
respect thereto other than as expressly set forth in this Article VIII.

      Section 8.3. Investor's Compliance. Nothing in this Article VIII shall
affect in any way the Investor's obligations to comply with all applicable
securities laws.

                                   ARTICLE IX

                          INDEMNIFICATION; ARBITRATION

      Section 9.1. Indemnification. The Company agrees to indemnify and hold
harmless the Investor, its partners, Affiliates, officers, directors, employees,
and duly authorized agents, and each Person or entity, if any, who controls the
Investor within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act, together with its controlling persons from and against any
Damages, joint or several, and any action in respect thereof to which the
Investor, its partners, Affiliates, officers, directors, employees, and duly
authorized agents, and any such controlling person becomes subject to, resulting
from, arising out of or relating to any misrepresentation, breach of warranty or
nonfulfillment of or failure to perform any covenant or agreement on the part of
Company contained in this Agreement, as such Damages are incurred, unless such
Damages result primarily from the Investor's gross negligence, recklessness or
bad faith in performing its obligations under this Agreement; provided, however,
that the maximum aggregate liability of the Company shall be limited to the
amount actually invested by the Investor under this Agreement, and provided,
further, that in no event shall this provision be deemed to limit any rights to
indemnification arising under the Registration Rights Agreement.

      Section 9.2. Method of Asserting Indemnification Claims. All claims for
indemnification by any Indemnified Party (as defined below) under Section 9.1
shall be asserted and resolved as follows:

            (a) In the event any claim or demand in respect of which any person
claiming indemnification under any provision of Section 9.1 (an "Indemnified
Party") might seek indemnity under Section 9.1 is asserted against or sought to
be collected from such Indemnified Party by a person other than the Company, the
Investor or any Affiliate of the Company (a "Third Party Claim"), the
Indemnified Party shall deliver a written notification, enclosing a copy of all
papers served, if any, and specifying the nature of and basis for such Third
Party Claim and for the Indemnified Party's claim for indemnification that is
being asserted under any provision of Section 9.1 against any person (the
"Indemnifying Party"), together with the amount or, if not then reasonably
ascertainable, the estimated amount, determined in good faith, of such Third
Party Claim (a "Claim Notice") with reasonable promptness to the Indemnifying
Party. If the Indemnified Party fails to provide the Claim Notice with
reasonable promptness after the Indemnified Party receives notice of such Third
Party Claim, the Indemnifying Party shall not be obligated to indemnify the
Indemnified Party with respect to such Third Party Claim to the extent that the
Indemnifying Party's ability to defend has been irreparably prejudiced by such
failure of the Indemnified Party. The Indemnifying Party shall notify the
Indemnified Party as soon as practicable within the period ending thirty (30)
calendar days following receipt by the Indemnifying Party of either a Claim
Notice or an Indemnity Notice (as defined below) (the "Dispute Period") whether
the Indemnifying Party disputes its liability or the amount of its liability to
the Indemnified Party under Section 9.1 and whether the Indemnifying Party
desires, at its sole cost and expense, to defend the Indemnified Party against
such Third Party Claim.

            (i) If the Indemnifying Party notifies the Indemnified Party within
            the Dispute Period that the Indemnifying Party desires to defend the
            Indemnified Party with respect to the Third Party Claim pursuant to
            this Section 9.2(a), then the Indemnifying Party shall have the
            right to defend, with counsel reasonably satisfactory to the
            Indemnified Party, at the sole cost and expense of the Indemnifying
            Party, such Third Party Claim by all appropriate proceedings, which
            proceedings shall be vigorously and diligently prosecuted by the
            Indemnifying Party to a final conclusion or will be settled at the
            discretion of the Indemnifying Party (but only with the consent of
            the Indemnified Party in the case of any settlement that provides
            for any relief other than the payment of monetary damages or that
            provides for the payment of monetary damages as to which the
            Indemnified Party shall not be indemnified in full pursuant to
            Section 9.1). The Indemnifying Party shall have full control of such
            defense and proceedings, including any compromise or settlement
            thereof; provided, however, that the Indemnified Party may, at the
            sole cost and expense of the Indemnified Party, at any time prior to
            the Indemnifying Party's delivery of the notice referred to in the
            first sentence of this clause (i), file any motion, answer or other
            pleadings or take any other action that the Indemnified Party
            reasonably believes to be necessary or appropriate to protect its
            interests; and provided further, that if requested by the
            Indemnifying Party, the Indemnified Party will, at the sole cost and
            expense of the Indemnifying Party, provide reasonable cooperation to
            the Indemnifying Party in contesting any Third Party Claim that the
            Indemnifying Party elects to contest. The Indemnified Party may
            participate in, but not control, any defense or settlement of any
            Third Party Claim controlled by the Indemnifying Party pursuant to
            this clause (i), and except as provided in the preceding sentence,
            the Indemnified Party shall bear its own costs and expenses with
            respect to such participation. Notwithstanding the foregoing, the
            Indemnified Party may take over the control of the defense or
            settlement of a Third Party Claim at any time if it irrevocably
            waives its right to indemnity under Section 9.1 with respect to such
            Third Party Claim.

            (ii) If the Indemnifying Party fails to notify the Indemnified Party
            within the Dispute Period that the Indemnifying Party desires to
            defend the Third Party Claim pursuant to Section 9.2(a), or if the
            Indemnifying Party gives such notice but fails to prosecute
            vigorously and diligently or settle the Third Party Claim, or if the
            Indemnifying Party fails to give any notice whatsoever within the
            Dispute Period, then the Indemnified Party shall have the right to
            defend, at the sole cost and expense of the Indemnifying Party, the
            Third Party Claim by all appropriate proceedings, which proceedings
            shall be prosecuted by the Indemnified Party in a reasonable manner
            and in good faith or will be settled at the discretion of the
            Indemnified Party (with the consent of the Indemnifying Party, which
            consent will not be unreasonably withheld). The Indemnified Party
            will have full control of such defense and proceedings, including
            any compromise or settlement thereof; provided, however, that if
            requested by the Indemnified Party, the Indemnifying Party will, at
            the sole cost and expense of the Indemnifying Party, provide
            reasonable cooperation to the Indemnified Party and its counsel in
            contesting any Third Party Claim which the Indemnified Party is
            contesting. Notwithstanding the foregoing provisions of this clause
            (ii), if the Indemnifying Party has notified the Indemnified Party
            within the Dispute Period that the Indemnifying Party disputes its
            liability or the amount of its liability hereunder to the
            Indemnified Party with respect to such Third Party Claim and if such
            dispute is resolved in favor of the Indemnifying Party in the manner
            provided in clause (iii) below, the Indemnifying Party will not be
            required to bear the costs and expenses of the Indemnified Party's
            defense pursuant to this clause (ii) or of the Indemnifying Party's
            participation therein at the Indemnified Party's request, and the
            Indemnified Party shall reimburse the Indemnifying Party in full for
            all reasonable costs and expenses incurred by the Indemnifying Party
            in connection with such litigation. The Indemnifying Party may
            participate in, but not control, any defense or settlement
            controlled by the Indemnified Party pursuant to this clause (ii),
            and the Indemnifying Party shall bear its own costs and expenses
            with respect to such participation.

            (iii) If the Indemnifying Party notifies the Indemnified Party that
            it does not dispute its liability or the amount of its liability to
            the Indemnified Party with respect to the Third Party Claim under
            Section 9.1 or fails to notify the Indemnified Party within the
            Dispute Period whether the Indemnifying Party disputes its liability
            or the amount of its liability to the Indemnified Party with respect
            to such Third Party Claim, the Damages in the amount specified in
            the Claim Notice shall be conclusively deemed a liability of the
            Indemnifying Party under Section 9.1 and the Indemnifying Party
            shall pay the amount of such Damages to the Indemnified Party on
            demand. If the Indemnifying Party has timely disputed its liability
            or the amount of its liability with respect to such claim, the
            Indemnifying Party and the Indemnified Party shall proceed in good
            faith to negotiate a resolution of such dispute, and if not resolved
            through negotiations within the period of thirty (30) calendar days
            immediately following the Dispute Period, such dispute shall be
            resolved by arbitration in accordance with Section 9.3.

            (b) In the event any Indemnified Party should have a claim under
Section 9.1 against the Indemnifying Party that does not involve a Third Party
Claim, the Indemnified Party shall deliver a written notification of a claim for
indemnity under Section 9.1 specifying the nature of and basis for such claim,
together with the amount or, if not then reasonably ascertainable, the estimated
amount, determined in good faith, of such claim (an "Indemnity Notice") with
reasonable promptness to the Indemnifying Party. The failure by any Indemnified
Party to give the Indemnity Notice shall not impair such party's rights
hereunder except to the extent that the Indemnifying Party demonstrates that it
has been irreparably prejudiced thereby. If the Indemnifying Party notifies the
Indemnified Party that it does not dispute the claim or the amount of the claim
described in such Indemnity Notice or fails to notify the Indemnified Party
within the Dispute Period whether the Indemnifying Party disputes the claim or
the amount of the claim described in such Indemnity Notice, the Damages in the
amount specified in the Indemnity Notice will be conclusively deemed a liability
of the Indemnifying Party under Section 9.1 and the Indemnifying Party shall pay
the amount of such Damages to the Indemnified Party on demand. If the
Indemnifying Party has timely disputed its liability or the amount of its
liability with respect to such claim, the Indemnifying Party and the Indemnified
Party shall proceed in good faith to negotiate a resolution of such dispute, and
if not resolved through negotiations within the period of thirty (30) calendar
days immediately following the Dispute Period, such dispute shall be resolved by
arbitration in accordance with

      Section 9.3. Arbitration. Any dispute under this Agreement (including,
without limitation, pursuant to Section 9.2) the Convertible Notes or the
Warrants shall be submitted to arbitration and shall be finally and conclusively
determined by the decision of a board of arbitration consisting of three (3)
members (the "Board of Arbitration") selected as hereinafter provided. Each of
the Company, on the one hand, and the Investor and/or any other Indemnified
Party, on the other hand, shall select one (1) member, and the third member
shall be selected by mutual agreement of the other members, or if the other
members fail to reach agreement on a third member within twenty (20) days after
their selection, such third member shall thereafter be selected by the American
Arbitration Association upon application made to it for such purpose by the
other members. The Board of Arbitration shall meet on consecutive business days
in New York City, New York or such other place as a majority of the members of
the Board of Arbitration determines more appropriate, and shall reach and render
a decision in writing (concurred in by a majority of the members of the Board of
Arbitration). In connection with rendering its decision, the Board of
Arbitration shall adopt and follow such rules and procedures as a majority of
the members of the Board of Arbitration deems necessary or appropriate. To the
extent practicable, decisions of the Board of Arbitration shall be rendered no
more than thirty (30) calendar days following commencement of proceedings with
respect thereto. The Board of Arbitration shall cause its written decision to be
delivered to the Company and the Investor and/or any other Indemnified Party.
Any decision made by the Board of Arbitration (either prior to or after the
expiration of such thirty (30) calendar day period) shall be final, binding and
conclusive on the Company and the Investor and/or any other Indemnified Party
and entitled to be enforced to the fullest extent permitted by law and entered
in any court of competent jurisdiction. The non-prevailing party to any
arbitration shall bear the expense of both parties in relation thereto,
including but not limited to the parties' attorneys' fees, if any, and the
expenses and fees of the Board of Arbitration.

Agreement or the transactions contemplated hereby.
