     THIS WARRANT  AGREEMENT (this  "Agreement")  dated May 22, 1997 is made and
entered into by and between Casdim  International  Systems,  Inc., a corporation
organized under the laws of the State of Delaware (the  "Company"),  and Lydford
Ltd.(the "Warrant Holder").

     Subject to the terms and conditions  hereof, the Company agrees to issue to
the Warrant  Holder,  warrants as  hereinafter  described  (the  "Warrants")  to
purchase up to an aggregate  of 200,000  shares of the common  stock,  par value
$.01 per share (the  "Common  Stock"),  of the  Company at a price of $.0001 per
Share. As used herein, the terms "Share" or "Shares" shall mean collectively the
Common Stock  issuable  upon  exercise of the Warrants  together  with any other
securities  issuable  upon  such  exercise  as  provided  in  Section  8 of this
Agreement.  Terms which are  capitalized  but not defined  herein shall have the
same meanings as in the Placement Agreement.

     For the purpose of defining  the terms and  provisions  of the Warrants and
the respective  rights and obligations  thereunder,  the Company and the Warrant
Holder, for value received, hereby agree as follows:

     Section 1. Transferability and Form of Warrants.

     1.1.  Registration.  The Warrants shall be numbered and shall be registered
on the books of the Company when issued,  in accordance with Delaware  corporate
practice.

     1.2. Transfer.  The Warrants shall be transferable only on the books of the
Company  maintained at its principal  office in New York,  New York, or wherever
its principal office may then be located, upon delivery thereof duly endorsed by
the  Warrantholder  seeking such transfer or by its duly authorized  attorney or
representative,  accompanied  by proper  evidence of  succession,  assignment or
authority to transfer.  Upon any  registration  of transfer,  the Company  shall
execute and deliver new Warrants to the person entitled thereto.

     1.3.  Form of Warrants.  The form of  certificate  evidencing  the Warrants
shall be substantially  as set forth in Exhibit A attached hereto.  Certificates
evidencing  the  Warrants  shall be  executed  on behalf of the  Company  by its
Chairman or by any Vice President,  shall be attested to by its Secretary or any
Assistant Secretary, and shall be dated as of the date of execution thereof.

     1.4.  Legend on Common  Stock.  The  Warrants  and the Shares have not been
registered  under the  Securities  Act of 1933,  as amended  (the  "Act").  Each
certificate  for Shares shall bear the following  legend unless,  at the time of
exercise,  such  Shares are the subject of a  currently  effective  registration
statement under the Act:









          "THE SECURITIES  REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED  UNDER THE UNITED STATES  SECURITIES ACT OF 1933 OR
          THE SECURITIES  LAWS OF ANY STATE OF THE UNITED  STATES.  SUCH
          SECURITIES MAY NOT BE SOLD, ASSIGNED, EXCHANGED,  HYPOTHECATED
          OR OTHERWISE  TRANSFERRED  IN ANY MANNER  EXCEPT IN COMPLIANCE
          WITH SECTION 11 OF THE AGREEMENT BY AND BETWEEN THE ISSUER AND
          LYDFORD LTD. DATED MAY 22, 1997."

     Any  certificate  issued at any time in  exchange or  substitution  for any
certificate bearing such legend (except a new certificate issued upon completion
of a public distribution  pursuant to a registration  statement under the Act of
the securities  represented thereby) shall also bear the above legend unless, in
the opinion of the Company's counsel, the securities represented thereby need no
longer be subject to such restrictions.

     Section 2. Exchange of Warrant Certificate.  Any Warrant certificate may be
exchanged for another  certificate or certificates  entitling a Warrantholder to
purchase a like aggregate  number of Shares as the  certificate or  certificates
surrendered  then entitles such  Warrantholder  to purchase.  Any  Warrantholder
desiring to exchange a Warrant  certificate  shall make such  request in writing
delivered  to  the  Company,  and  shall  surrender,   properly  endorsed,   the
certificate  evidencing the Warrant to be so exchanged.  Thereupon,  the Company
shall  execute  and  deliver  to  the  person  entitled  thereto  a new  Warrant
certificate as so requested.

     Section 3. Term of Warrants; Exercise of Warrants

     (a) Subject to the terms of this Agreement,  each Warrantholder  shall have
the right, at any time during the period commencing at 9:00 a.m.,  Eastern Time,
on May 22, 1997 (the "Commencement Date") and ending at 5:00 p.m., Eastern Time,
on May 21, 2002 (the "Termination Date"), to purchase from the Company up to the
number of fully paid and  nonassessable  Shares which such  Warrantholder may at
the time be entitled to purchase  pursuant to this Agreement,  upon surrender to
the Company at its principal office of the certificates  evidencing the Warrants
to be exercised,  with the purchase form on the reverse  thereof duly  completed
and signed,  and upon payment to the Company of the Warrant Price (as defined in
and determined in accordance  with the provisions of this Section 3 and Sections
7 and 8 hereof) for the number of Shares in respect of which such  Warrants  are
then exercised,  but in no event for fewer than 100 Shares (unless fewer than an
aggregate of 100 Shares are then purchasable under all outstanding Warrants held
of record by a  Warrantholder).  Payment of the aggregate Warrant Price shall be
made in cash or by  certified  or  cashier's  check,  in next day funds,  or any
combination thereof.



                                       -2-







     (b) Upon surrender of Warrant  certificates,  payment of the Warrant Price,
the Company shall issue and cause to be delivered with all  reasonable  dispatch
to or upon the  written  order of a  Warrantholder,  and  (subject to Section 11
hereof) in such name or names as such Warrantholder may designate, a certificate
or  certificates  for the number of full Shares so acquired upon the exercise of
the Warrant,  together with cash, as provided in Section 9 hereof, in respect of
any fractional Shares otherwise  issuable upon such surrender.  Such certificate
or certificates shall be deemed to have been issued and any person so designated
to be named  therein  shall be deemed to have  become a holder of record of such
Shares as of the date of surrender of the Warrants  being  exercised  payment of
the  Warrant  Price   notwithstanding   that  the  certificate  or  certificates
representing  such securities shall not actually have been delivered or that the
stock transfer books of the Company shall then be closed.  The Warrants shall be
exercisable  at the election of a  Warrantholder  either in full or from time to
time in part  and,  in the  event  that a  certificate  evidencing  Warrants  is
exercised  in respect of fewer than all of the Shares  specified  therein at any
time prior to the Termination  Date, a new certificate  evidencing the remaining
portion of the Warrants shall be issued by the Company.

     Section 4. Payment of Taxes.  The Company  will pay all taxes and fees,  if
any,  attributable  to the initial  issuance of the  Warrants or the issuance of
Shares upon  exercise of the  Warrants;  provided  that the Company shall not be
required to pay any tax or fee which may be payable in respect of any  secondary
transfer of the Warrants or such Shares.

     Section  5.  Mutilated  or Missing  Warrants.  In case the  certificate  or
certificates  evidencing  any  Warrants  shall be  mutilated,  lost,  stolen  or
destroyed,  the Company  shall,  at the request of the  affected  Warrantholder,
issue and deliver in exchange and substitution for and upon  cancellation of the
mutilated  certificate or  certificates,  or in lieu of and substitution for the
certificate or certificates lost, stolen or destroyed, a new Warrant certificate
or certificates of like tenor and  representing an equivalent right or interest,
but only upon receipt of evidence satisfactory to the Company of the loss, theft
or destruction of such Warrant and, if requested, at the cost and expense of the
Warrantholder,  a bond of  indemnity  in form  and  amount  satisfactory  to the
Company.  Applicants for such substitute Warrants  certificate shall also comply
with such other reasonable regulations as the Company may prescribe.

     Section 6.  Reservation of Common Stock.  There has been reserved,  and the
Company  shall  at all  times  keep  reserved  so  long as any  Warrants  remain
outstanding, out of its authorized share capital, such number of Common Stock as
shall be subject to purchase  under all  outstanding  Warrants.  Every  transfer
agent for the Common Stock and other securities of the Company issuable upon the
exercise of Warrants will be irrevocably authorized and directed at all times to
reserve such number of authorized shares of Common Stock and other securities as
shall be  requisite  for such  purpose.  The  Company  will  keep a copy of this
Agreement  on file with  every  transfer  agent for the  Common  Stock and other
securities  of the  Company  issuable  upon the  exercise of the  Warrants.  The
Company will supply every such transfer agent with duly executed

                                       -3-







stock and other certificates,  as appropriate, for such purpose and will provide
or otherwise make available any cash which may be payable as provided in Section
9 hereof.

     Section 7. Warrant Price. "Warrant Price" shall mean the price per Share at
which Shares shall at any time be purchasable upon the exercise of the Warrants.
The initial  Warrant  Price shall be $1.00,  subject to  adjustment  pursuant to
Section 8 hereof.

     Section 8. Adjustment of Number and Kind of Securities. The number and kind
of  securities  purchasable  upon the  exercise of the  Warrants and the Warrant
Price shall be subject to  adjustment  from time to time upon the  happening  of
certain events, as follows:

         8.1.  Adjustments.

               (a) In case the Company  shall (i) pay a dividend in Common Stock
          or make a distribution in Common Stock, (ii) subdivide its outstanding
          Common  Stock,  (iii)  combine  its  outstanding  Common  Stock into a
          smaller  number  of  shares  of  Common  Stock,   or  (iv)  issue,  by
          reclassification of its Common Stock, other securities of the Company,
          the number of Shares or other securities  purchasable upon exercise of
          the Warrants  immediately prior thereto shall be adjusted so that each
          Warrantholder  shall be  entitled  to  receive  the kind and number of
          shares of Common  Stock or other  securities  of the Company  which it
          would have owned or would have been  entitled  to receive  immediately
          after the  happening  of any of the events  described  above,  had the
          Warrants  been  exercised  immediately  prior to the happening of such
          event or any record date with respect  thereto.  Any  adjustment  made
          pursuant to this subsection 8.1(a) shall become effective  immediately
          on the effective date of such event retroactive to the record date, if
          any, for such event.

               (b) In case the Company shall issue rights, options,  warrants or
          convertible  securities  to all or  substantially  all  holders of its
          Common Stock  without any charge to such  holders,  entitling  them to
          subscribe for or purchase  shares of Common Stock at a price per share
          which,  at the record  date  mentioned  below,  is lower than the then
          effective Warrant Price  (calculated  pursuant to this Section 8), the
          number of Shares  thereafter  purchasable  upon the  exercise  of each
          Warrant  shall be  determined  by  multiplying  the  number  of Shares
          theretofore purchasable upon exercise of the Warrant by a fraction, of
          which the  numerator  shall be the  number  of shares of Common  Stock
          outstanding immediately prior to the issuance of such rights, options,
          warrants  or  convertible  securities  plus the  number of  additional
          Common Stock offered for  subscription  or purchase,  and of which the
          denominator  shall be the number of shares of Common Stock outstanding
          immediately prior to the issuance of such rights, options, warrants or
          convertible  securities  plus the number of shares which the aggregate
          offering price of the total number of shares offered would purchase at
          such then  effective  Warrant  Price.  Such  adjustment  shall be made
          whenever such rights, options,  warrants or convertible securities are
          issued, and shall become effective  immediately and retroactive to the
          record date for the determination of

                                       -4-







         shareholders  entitled to receive  such  rights,  options,  warrants or
         convertible  securities,  provided no such adjustment shall be made for
         rights issued in connection  with what is customarily  referred to as a
         "poison pill" or "shareholder rights plan."

               (c) In case the Company shall  distribute to all or substantially
          all  holders of its Common  Stock  evidences  of its  indebtedness  or
          assets  (excluding cash dividends or distributions out of earnings) or
          rights,  options,  warrants or convertible  securities  containing the
          right to subscribe for or purchase Shares (excluding those referred to
          in subsection 8.1(b) above and rights in connection with a shareholder
          rights  plan),  then in each  case the  number  of  Shares  thereafter
          purchasable  upon the exercise of the Warrants  shall be determined by
          multiplying the number of Shares theretofore purchasable upon exercise
          of the  Warrants by a fraction,  of which the  numerator  shall be the
          then  effective  Warrant  Price  as of the  date of such  distribution
          calculated  pursuant to this  Section 8, and of which the  denominator
          shall be such then effective Warrant Price on such date minus the then
          fair value  (determined as provided in subparagraph  (f) below) of the
          portion of the assets or evidences of  indebtedness  so distributed or
          of  such  subscription  rights,   options,   warrants  or  convertible
          securities  applicable  to one share.  Such  adjustment  shall be made
          whenever any such  distribution is made and shall become  effective on
          the  date of  distribution  retroactive  to the  record  date  for the
          determination of shareholders entitled to receive such distribution.

               (d) No adjustment in the number of Shares purchasable pursuant to
          the Warrants shall be required unless such adjustment would require an
          increase  or  decrease of at least one percent in the number of Shares
          then purchasable upon the exercise of the Warrants or, if the Warrants
          are not then  exercisable,  the number of Shares  purchasable upon the
          exercise  of the  Warrants  on the  first  date  thereafter  that  the
          Warrants become  exercisable;  provided that any adjustments  which by
          reason  of  this  subsection  8.1(d)  are  not  required  to  be  made
          immediately  shall be carried  forward  and taken into  account in any
          subsequent adjustment.

               (e) Whenever the number of Shares  purchasable  upon the exercise
          of a Warrant  is  adjusted,  as herein  provided,  the  Warrant  Price
          payable upon exercise of such Warrant shall be adjusted by multiplying
          such Warrant Price immediately prior to such adjustment by a fraction,
          of which the numerator shall be the number of Shares  purchasable upon
          the exercise of the Warrant immediately prior to such adjustment,  and
          of which the denominator  shall be the number of Shares so purchasable
          upon the exercise of the Warrant immediately thereafter.

               (f) Whenever the number of Shares  purchasable  upon the exercise
          of Warrants is adjusted as herein provided, the Company shall cause to
          be promptly mailed to the  Warrantholders by first class mail, postage
          prepaid,  notice of such  adjustment  and a  certificate  of the chief
          financial officer of the Company setting forth the number of Shares

                                       -5-







         purchasable upon the exercise of the Warrants after such adjustment,  a
         brief  statement  of  the  facts  requiring  such  adjustment  and  the
         computation by which such adjustment was made.

               (g) For the purpose of this subsection 8.1, the term Common Stock
          shall  mean (i) the class of Common  Stock  designated  as the  Common
          Stock of the Company at the date of this Agreement,  or (ii) any other
          class of shares resulting from successive changes or  reclassification
          of such Common  Stock  consisting  solely of changes in par value,  or
          from par value to no par value,  or from no par value to par value. In
          the event that at any time, as a result of an adjustment made pursuant
          to this Section 8, a  Warrantholder  shall become entitled to purchase
          any  securities  of the Company  other than Common  Stock,  (i) if the
          Warrantholders'  right to  purchase  is on any other  basis  than that
          available to all holders of the Common Stock, the Company shall obtain
          an opinion of an  independent  investment  banking  firm  valuing such
          other  securities  and  (ii)  thereafter  the  number  of  such  other
          securities  so  purchasable  upon  exercise of the  Warrants  shall be
          subject  to  adjustment  from time to time in a manner and on terms as
          nearly equivalent as practicable to the provisions with respect to the
          Common Stock contained in this Section 8.

               (h) Upon the  expiration  of any  rights,  options,  warrants  or
          conversion  privileges,  if such  shall not have been  exercised,  the
          number of Shares  purchasable  upon exercise of the  Warrants,  to the
          extent the Warrants  have not then been  exercised,  shall,  upon such
          expiration,  be readjusted and shall  thereafter be such as they would
          have  been had they  been  originally  adjusted  (or had the  original
          adjustment not been required,  as the case may be) on the basis of (A)
          the fact  that the only  shares of  Common  Stock so  issued  were the
          shares  of  Common  Stock,  if any,  actually  issued or sold upon the
          exercise of such rights,  options,  warrants or conversion privileges,
          and (B) the fact that such shares of Common Stock, if any, were issued
          or sold for the  consideration  actually  received by the Company upon
          such exercise plus the consideration, if any, actually received by the
          Company for the issuance,  sale or grant of all such rights,  options,
          warrants or conversion privileges whether or not exercised;  provided,
          however, that no such readjustment shall have the effect of decreasing
          the number of Shares  purchasable  upon exercise of the Warrants by an
          amount in excess of the  amount of the  adjustment  initially  made in
          respect  of the  issuance,  sale or  grant  of such  rights,  options,
          warrants or conversion privileges.

     8.2. No Adjustment for Dividends.  Except as provided in subsection 8.1, no
adjustment to the Warrants or any  provision or condition  thereof in respect of
any dividends or distributions  out of earnings shall be made during the term of
the Warrants or upon the exercise of Warrants.

     8.3. No Adjustment in Certain Cases.  No adjustments to the Warrants or any
provision or condition  thereof shall be made pursuant to Section 3 or Section 8
hereof in connection with (i) the issuance of any Securities sold as part of the
Offering  pursuant to the Placement  Agreement,  or the issuance of Common Stock
upon exercise of the Warrants, or (ii) the grant or exercise of

                                       -6-







the options to purchase  Common Stock under the  Company's  Share Option Plan or
any future  option  plan for the sole  benefit of the  Company's  employees  and
directors.

     8.4. Preservation of Purchase Rights upon Reclassification,  Consolidation,
etc. In case of any  consolidation  of the Company with or merger of the Company
into another  entity or in case of any sale or conveyance  to another  entity of
the property,  assets or business of the Company as an entirety or substantially
as an entirety,  the Company or such successor or purchasing entity, as the case
may  be,  shall  execute  with  the   Warrantholders   an  agreement   that  the
Warrantholders  shall have the right  thereafter,  upon exercise of the Warrants
and  payment  of  the  Warrant  Price  in  effect   immediately  prior  to  such
consolidation,  merger or sale,  to  purchase  the kind and amount of shares and
other securities and property which it would have been entitled to receive after
the happening of such consolidation, merger, sale or conveyance had the Warrants
been exercised  immediately prior thereto. In the event of a merger described in
Section  368(a)(2)(E)  of the Internal  Revenue  Code of 1986 (or any  successor
provision),  in which the  Company is the  surviving  corporation,  the right to
purchase  Shares under the Warrants  shall  terminate on the date of such merger
and  thereupon  the  Warrants  shall  become  null  and  void,  but  only if the
controlling  corporation  (after such event) shall agree to  substitute  for the
Warrants  its  warrants  entitling  the holder  thereof to purchase the kind and
amount of shares  and other  securities  and  property  which it would have been
entitled to receive had the Warrants been  exercised  immediately  prior to such
merger. Any such agreements referred to in this subsection 8.4 shall provide for
adjustments,  which shall be as nearly  equivalent as may be  practicable to the
adjustments  provided for in Section 8 hereof,  and shall contain  substantially
the same terms,  conditions and provisions as are contained  herein  immediately
prior to such event. The provisions of this subsection 8.4 shall similarly apply
to successive consolidations, mergers, sales or conveyances.

     8.5.  Nominal Value of Common  Stock.  Before taking any action which would
cause an  adjustment  effectively  reducing  the  portion of the  Warrant  Price
allocable to each Share below the then  nominal  value per Share  issuable  upon
exercise of the Warrants,  the Company will take any corporate action which may,
in the  opinion of its  counsel,  be  necessary  in order that the  Company  may
validly and legally issue fully paid and  nonassessable  Shares upon exercise of
the Warrants.

     8.6.  Independent  Public  Accountants.  The  Company  may retain a firm of
independent  public accountants in the United States (which may be any such firm
regularly  employed by the Company) to make any computation  required under this
Section  8, and a  certificate  signed by such  firm  shall be  evidence  of the
correctness of any computation made under this Section 8.

     8.7. Statement on Warrant Certificates.  Irrespective of any adjustments in
the  number  of  securities   issuable   upon  exercise  of  Warrants,   Warrant
certificates  theretofore or thereafter  issued may continue to express the same
number of securities as are stated in the similar Warrant certificates initially
issuable  pursuant to this Agreement.  However,  the Company may, at any time in
its reasonable  discretion,  make any change in the form of Warrant  certificate
that it may deem

                                       -7-







appropriate  and that does not affect the  substance  thereof;  and any  Warrant
certificate  hereafter  issued,  whether upon registration of transfer of, or in
exchange or substitution for, an outstanding Warrant certificate,  may be in the
form so changed.

     Section 9.  Fractional  Interests;  Market Price.  The Company shall not be
required to issue  fractional  Shares upon the exercise of any  Warrant.  If any
fraction  of a Share  would,  except for the  provisions  of this  Section 9, be
issuable on the  exercise of any Warrant (or  specified  portion  thereof),  the
Company shall pay an amount in cash equal to the Market Price multiplied by such
fraction.  For all purposes of this  Agreement,  the term Market Price as of any
specified date shall mean (i) if the Common Stock is traded in the United States
over-the-counter  market  and not on the Nasdaq  System or on any United  States
national securities exchange,  the average of the mean between the bid and asked
prices  of the  Common  Stock  on  each of the  five  consecutive  trading  days
immediately  preceding  the  date  in  question,  as  reported  by the  National
Quotation  Bureau  Incorporated or an equivalent  generally  accepted  reporting
service, or (ii) if the Common Stock is traded on the Nasdaq System or on one or
more United States  national  securities  exchanges,  the average,  for the five
consecutive  trading days  immediately  preceding  the date in question,  of the
daily  closing  price of the  Common  Stock on the  Nasdaq  System  or the daily
closing  price for  consolidated  transactions  on the  principal  United States
national  securities  exchange on which the Common Stock is listed,  or (iii) if
the Common Stock is not traded in the United States over-the-counter market, the
Nasdaq System or any United States national  securities  exchange,  the average,
for  the  five  consecutive  trading  days  immediately  preceding  the  date in
question,  of the  daily  closing  price of the  Common  Stock on the  principal
non-United  States  exchange  on which the  Common  Stock is  listed.  The daily
closing  price  referred  to in clauses  (ii) and (iii)  above shall be the last
reported  sale price on the day in question or, if no reported  sale takes place
on such day, the average of the reported closing bid and asked prices.

     Section 10. No Rights as Shareholder;  Notices to  Warrantholders.  Nothing
contained in this  Agreement or in the Warrants shall be construed as conferring
upon  the  Warrantholder  or  any  transferee  of  a  Warrant  any  rights  as a
shareholder of the Company,  including  (without  limitation) the right to vote,
receive dividends, consent or receive notices as a shareholder in respect of any
meeting of  shareholders  for the  election of  directors  of the Company or any
other matter.  If, however,  at any time prior to the expiration of the Warrants
and prior to their  exercise in full,  any one or more of the  following  events
shall occur:

               (a) any action  which  would  require an  adjustment  pursuant to
          Section 8.1 or 8.4; or

               (b) a  dissolution,  liquidation  or  winding  up of the  Company
          (other than in connection with a consolidation,  merger or sale of its
          property,  assets and business as an entirety or  substantially  as an
          entirety) shall be proposed;


                                       -8-







then the  Company  shall  give  notice in  writing  of such event to each of the
Warrantholders,  as provided in Section 14 hereof, at least 20 days prior to the
date fixed as a record  date or the date of closing the  transfer  books for the
determination   of  the   shareholders   entitled  to  any  relevant   dividend,
distribution,  subscription  rights or other rights or for the  determination of
shareholders  entitled  to vote on such  proposed  dissolution,  liquidation  or
winding up. Such notice  shall  specify  such record date or the date of closing
the transfer  books,  as the case may be. Failure to mail or receive such notice
or any defect  therein  shall not affect the  validity of any action  taken with
respect thereto.

     Section 11. Restrictions on Transfer; Registration Rights.

     (a) The Warrant Holder agrees and undertakes that if it proposes to sell or
otherwise transfer any Warrants or Shares and if such Warrants or Shares are not
then registered for resale pursuant to an effective registration statement under
the Act, the  Warrantholder  proposing to make such transfer  shall give written
notice to the Company  describing  briefly the manner in which any such proposed
transfer is to be made;  and no such  transfer  shall be made unless the Company
shall  notify  such   Warrantholder  that  in  the  opinion  counsel  reasonably
satisfactory to such  Warrantholder,  registration under the Act is not required
with respect to such transfer.

     (b)  Within  30 days of the date of this  Agreement  the  Company  shall be
obligated to the Warrant Holder to file a Registration  Statement  under the the
Act covering the Shares  issuable  upon  exercise of the Warrants in  conformity
with the provisions of a certain  Registration  Rights Agreement entered into by
the Warrant Holder and the Company on May 21, 1997.

     (c) In  connection  with  any  Registration  Statement  filed  pursuant  to
paragraph  (b) of this Section 11, the Company  shall take such action as may be
necessary or  appropriate to comply with the securities or blue sky laws of such
states of the United  States as shall  reasonably  be  requested  by the Warrant
Holder,  and shall do any and all other acts which may be necessary or advisable
to permit  the  proposed  sale or other  disposition  of the  Shares in any such
state;  provided  that in no event shall the Company be obligated in  connection
therewith to qualify as a foreign corporation or as a dealer in any jurisdiction
where it is not  already  so  qualified,  or to  execute a general  consent  for
service of process in suits  other than those  arising out of the offer and sale
of the Shares,  or to take any action which would  subject it to taxation in any
jurisdiction where it is not then so subject.

     (d) The Company's  obligations  under paragraph (b) of this Section 11 with
respect to the Warrant  Holder shall be  conditioned  in each  instance upon the
timely  receipt by the Company in writing of (i)  information  from such Warrant
Holder as to the proposed plan of distribution  of such Warrant  Holder's Shares
to be included in a Registration  Statement,  (ii) such other information as may
be required by law from such holder, or its underwriter or other agent,

                                       -9-







for inclusion in such  Registration  Statement,  and (iii) if such holder is not
the Warrant  Holder,  an agreement to be bound by the  provisions of Sections 12
and 13 of this Agreement.

     (e) The Warrant  Holder  will not make any sale of the Shares,  pursuant to
the registration  statement  referred to in this Section 11 without  effectively
causing the  prospectus  delivery  requirements  under the  Securities Act to be
satisfied.  The Warrant Holder acknowledges that there may occasionally be times
when the Company  must suspend the use of the  prospectus  forming a part of the
Registration  Statement  until such time as an  amendment  to such  registration
statement has been field by the Company and declared effective by the Commission
or until the Company has amended or supplemented  such  prospectus.  The Company
will use its best  efforts to cause such  amended  registration  statement to be
declared effective and/or to deliver such amended or supplemented  prospectus as
soon as possible.  The Warrant Holder hereby covenants that it will not sell any
Shares pursuant to said prospectus  during the period  commencing at the time at
which the Company gives the Warrant  Holder notice of the  suspension of the use
of said  prospectus  and ending at the time the Company gives the Warrant Holder
notice that the Warrant  Holder may  thereafter  effect  sales  pursuant to said
prospectus.

     (f)  The  Company  shall  pay all  fees,  disbursements  and  out-of-pocket
expenses  (other than the Warrant  Holder's  brokerage fees and  commissions and
legal fees)  payable in connection  with (i) any  Registration  Statement  filed
under paragraph 11(b) and (ii) compliance with applicable  state  securities and
blue sky laws.  The  Company at its expense  will supply the Warrant  Holders of
Shares  included in a Registration  Statement  with copies of such  Registration
Statement and the prospectus  included  therein and other related  documents and
opinions  and  no-action  letters,  in  such  quantities  as may  be  reasonably
requested  by  such   Warrantholders.   In  connection  with  each  Registration
Statement,  the Company shall furnish to holders of Shares included therein such
opinions of counsel,  comfort  letters of  accountants,  certificates  and other
documents that are customary in connection with  underwritten  public  offerings
and that are reasonably requested by such Warrantholders.

     Section 12. Indemnification.

     (a) In the event  that any  Registration  Statement  is filed  pursuant  to
Section  11  hereof,   the  Company  will   indemnify   and  hold  harmless  the
Warrantholder  identified as a selling security holder therein, and each person,
if any, who controls such  Warrantholder  within the meaning of the Act, against
any and all losses, claims, damages or liabilities,  joint or several (including
any reasonable  investigation,  legal and other expenses  incurred in connection
with,  and any amount paid in settlement  of, any action,  suit or proceeding or
any claim  asserted),  to which they or any of them may become subject under the
Act, the  Securities  Exchange Act of 1934, as amended (the  "Exchange  Act") or
other federal or state 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 (i) any  untrue  statement  or  alleged  untrue
statement of a material fact contained in any such Registration  Statement,  any
related preliminary prospectus, final prospectus,

                                      -10-







or amendment thereof or supplement  thereto,  or any related blue sky filing, or
(ii) the omission or alleged  omission to state therein a material fact required
to be stated  therein or necessary to make the statements  therein,  in light of
the circumstances under which they were made, not misleading;  provided that the
Company  shall not be liable  under this  section  12(a) in any such case to the
extent that any such losses,  claims, damages or liabilities arise solely out of
or are based upon an untrue  statement of a material  fact  contained in, or any
omission  of a material  fact from,  such  Registration  Statement,  preliminary
prospectus,  final  prospectus  or amendment  thereof or  supplement  thereto in
reliance upon, and in conformity with,  information  furnished in writing to the
Company by such Warrant Holder specifically for use therein. This indemnity will
be in addition to any liability which the Company may otherwise have.

     (b) The Warrant Holder will  indemnify and hold harmless the Company,  each
other person  referred to in subparts  (1), (2) and (3) of Section  11(a) of the
Act in respect of the  Registration  Statement,  and each  person,  if any,  who
controls the Company or any such person  within the meaning of Section 15 of the
Act, against any and all losses,  claims,  damages or liabilities (including any
reasonable investigation,  legal and other expenses incurred in connection with,
and any amount paid in  settlement  of, any action,  suit or  proceeding  or any
claim  asserted),  to which they, or any of them,  may become  subject under the
Act,  the Exchange Act or other  federal or state 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 (i) any  untrue
statement  or alleged  untrue  statement  of a material  fact  contained in such
Registration Statement, any related preliminary prospectus,  final prospectus or
amendment thereof or supplement thereto, or any related blue sky filing, or (ii)
the omission or alleged omission to state therein a material fact required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances  under which they were made, not  misleading,  in each case to the
extent, but only to the extent,  that such untrue statement or omission was made
in such  Registration  Statement,  preliminary  prospectus,  final prospectus or
amendment  thereof or  supplement  thereto in reliance  upon,  and in conformity
with,  information  furnished in writing to the Company by such  Warrant  Holder
specifically  for  use  therein.  This  indemnity  will  be in  addition  to any
liability which the Warrant Holder may otherwise have to the Company.

     (c) Any party that  proposes  to assert the right to be  indemnified  under
this Section 12 shall,  promptly after receipt of notice of the  commencement of
any action, suit or proceeding against such party in respect of which a claim is
to be made against an indemnifying  party or parties under this Section,  notify
each such indemnifying  party of the commencement  thereof,  enclosing a copy of
all papers  served.  No  indemnification  provided for in Section 12(a) or 12(b)
shall be  available  to any party who shall fail to give  notice as  provided in
this Section  12(c) if the party to whom notice was not given was unaware of the
proceeding to which such notice would have related and was materially prejudiced
by the  failure  to  give  such  notice,  but the  omission  so to  notify  such
indemnifying  party of any such action,  suit or proceeding shall not relieve it
from any liability  that it may have to any  indemnified  party  otherwise  than
under this Section 12 or Section 13. In case any such action, suit or proceeding
is brought against any

                                      -11-







indemnified  party and it notifies the  indemnifying  party of the  commencement
thereof, such indemnifying party will be entitled to participate in, and, to the
extent that it may wish,  jointly with any other  indemnifying  party  similarly
notified, to assume the defense thereof with counsel reasonably  satisfactory to
such indemnified  party,  and, after notice from the indemnifying  party to such
indemnified  party of its  election  so to assume the  defense  thereof  and the
approval by the  indemnified  party of such counsel  (which  approval  shall not
unreasonably be withheld),  the  indemnifying  party shall not be liable to such
indemnified party for any legal or other expenses,  except as provided below and
except for the reasonable costs of investigation  subsequently  incurred by such
indemnified party in connection with the defense thereof.  The indemnified party
shall  have the right to employ  its own  counsel  in any such  action,  suit or
proceeding  but the fees and expenses of such counsel shall be at the expense of
such indemnified  party unless (i) the employment of counsel by such indemnified
party has been  authorized  in writing  by the  indemnifying  parties,  (ii) the
indemnified party shall have reasonably concluded that there may be differing or
additional  defenses  available to it and not to one or more of the indemnifying
parties in such  action,  suit or  proceeding  (in which  case the  indemnifying
parties  shall not have the right to direct the defense of such action,  suit or
proceeding  on  behalf of the  indemnified  party),  or (iii)  the  indemnifying
parties  shall not have  employed  counsel to assume the  defense of such action
within a reasonable time after notice of the  commencement  thereof,  in each of
which cases the fees and expenses of the indemnified party's counsel shall be at
the expense of the indemnifying  parties;  however, the indemnifying party shall
not, in connection with any one such action,  suit or proceeding or separate but
substantially  similar  or related  actions,  suits or  proceedings  in the same
jurisdiction  arising out of the same general  allegations or circumstances,  be
liable for the  reasonable  fees and expenses of more than one separate  firm of
attorneys for the Warrant Holders and controlling  persons,  which firm shall be
designated  in writing by a majority  in interest  of such  Warrant  Holders and
controlling  persons  (based  upon  the  value  of the  Shares  included  in the
Registration  Statement).  An  indemnifying  party  shall not be liable  for any
settlement of any action, suit, proceeding or claim effected without its written
consent.

     Section  13.  Contribution.  In order  to  provide  for just and  equitable
contribution  in  circumstances  in which the  indemnification  provided  for in
Section 12 is due in accordance  with its terms but for any reason is held to be
unavailable or insufficient to hold harmless an indemnified  party,  the Company
(including for this purpose any controlling person of the Company,  any director
of the  Company  and any  officer of the  Company  who  signed the  Registration
Statement) on the one hand, and the Warrant Holders  (including for this purpose
any  controlling  persons  thereof)  on  the  other  hand,  shall,  in  lieu  of
indemnifying such indemnified party, contribute to the aggregate losses, claims,
damages  or  liabilities   referred  to  in  Section  12  above  (including  any
investigation,  legal and other expenses reasonably incurred in connection with,
and any amount paid in  settlement  of, any action,  suit or  proceeding  or any
claims asserted,  but after deducting any contribution received by or payable to
the Company from other  persons  other than the Warrant  Holders,  such as other
selling  securityholders,  persons who control the Company within the meaning of
the Act,  officers  of the Company who signed the  Registration  Statement,  and
directors of the Company),  (a) in such  proportion as is appropriate to reflect
the

                                      -12-







relative  benefits  received by the Company  and the  Warrant  Holders  from the
offering  or  offerings  covered by the  Registration  Statement  or, (b) if the
allocation  provided by clause (a) above is not permitted by applicable  law, in
such  proportion  as is  appropriate  to reflect not only the relative  benefits
referred to in clause (a) above but also the  relative  fault of the Company and
the  Warrant  Holders in  connection  with the  statements  or  omissions  which
resulted in such losses,  claims,  damages,  liabilities or expenses, as well as
any other relevant equitable  considerations.  The relative benefits received by
the  Company on the one hand and the  Warrant  Holder on the other hand shall be
deemed to be in the same  proportion as (x) the total proceeds (if any) received
by the  Company  from the  offering  or  offerings  covered by the  Registration
Statement  (net of  underwriting  discounts but before  deducting  expenses,  if
applicable), plus all cash proceeds received by the Company from the exercise of
the Warrants for the Shares of such Warrant Holder included in the  Registration
Statement,  bear to (y) the total proceeds  received by such Warrant Holder from
the sale of Shares included in the Registration Statement. The relative fault of
the Company and the Warrant  Holder shall be  determined  by reference to, among
other things,  whether the untrue or alleged untrue statement of a material fact
or omission  related to  information  supplied  by the  Company or such  Warrant
Holder,  and  their  relative  intent,  knowledge,  access  to  information  and
opportunity  to correct or prevent such  statement or omission.  The Company and
the Warrant Holder agree that it would not be just and equitable if contribution
pursuant to this Section 13 were determined by pro rata allocation  (even if the
Warrant  Holders  were  treated as one entity for such  purpose) or by any other
method of allocation which does not take account of the equitable considerations
referred to above. Notwithstanding the provisions of this Section 13, in no case
shall the Warrant Holder (except as may be provided by agreement  among them) be
liable or responsible for any amount in excess of the proceeds  received by such
Warrant  Holder  from  the  sale  of the  Shares  included  in the  Registration
Statement;  provided  that no  person  guilty  of  fraudulent  misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation.  For purposes of this  Section 13, each  person,  if any, who
controls  the  Warrant  Holder  within  the  meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act shall have the same rights to  contribution as
such Warrant  Holder,  and each person,  if any, who controls the Company within
the meaning of the Section 15 of the Act or Section  20(a) of the Exchange  Act,
each  director  of the  Company  and each  officer of the Company who shall have
signed the Registration Statement, shall have the same rights to contribution as
the  Company,  subject in each case to clauses  (i) and (ii) in the  immediately
preceding  sentence of this Section 13. Any party entitled to contribution will,
promptly  after  receipt  of  notice  of  commencement  of any  action,  suit or
proceeding  against such party in respect of which a claim for  contribution may
be made against  another  party or parties  under this  Section 13,  notify such
party or parties from whom  contribution  may be sought,  and the omission so to
notify such party or parties from whom  contribution may be sought shall relieve
the party or  parties  from whom  contribution  may be sought (if such party was
unaware of such action, suit or proceeding and was materially prejudiced by such
omission)  from any  liability  under  this  Section  13, but not from any other
obligation  it or they may have  hereunder or otherwise  than under this Section
13. No party shall be liable for contribution  with respect to any settlement of
an action, suit, proceeding or claim effected without

                                      -13-







its  written  consent.  The  obligations  of the Warrant  Holders to  contribute
pursuant to this Section 13 are several in proportion to their respective number
of Shares included in the Registration Statement, and not joint.

     Section 14.  Notices.  Any notice  pursuant to this  Agreement  shall be in
writing  and shall be deemed to have been duly  given (i) if given by  facsimile
transmission  on the  business  day on  which  such  transmission  is  sent  and
confirmed, (ii) if given by air courier, two business days following the date it
was sent or (iii) if mailed by certified  mail,  return receipt  requested,  ten
business  days  following  the date it was mailed,  to the  following  addresses
(unless another address is herein specified):

Each  party may from time to time  change  the  address  or fax  number to which
notices to it are to be  delivered or mailed  hereunder by notice in  accordance
herewith to the other party.

     Section 15. Successors.  All the covenants and provisions of this Agreement
by or for the benefit of the Company, the Warrant Holder shall bind and inure to
the benefit of their respective successors and assigns.

     Section 16. Merger or Consolidation  of the Company.  The Company shall not
merge  or  consolidate  with or  into  any  other  corporation  or  sell  all or
substantially all of its property to another corporation,  unless the provisions
of Section 8.4 are complied with.

     Section 17.  Applicable  Law;  Submission to  Jurisdiction.  THIS AGREEMENT
SHALL BE DEEMED TO BE A  CONTRACT  MADE  UNDER THE LAWS OF THE STATE OF NEW YORK
AND FOR ALL PURPOSES SHALL BE CONSTRUED IN ACCORDANCE  WITH THE INTERNAL LAWS OF
SAID SATE (WITHOUT  REFERENCE TO ITS RULES AS TO CONFLICTS OF LAWS). The Company
hereby  agrees to the exclusive  jurisdiction  of the courts of the State of New
York  sitting in the  County of New York or the  federal  courts  sitting in the
County of New York in connection with any action arising out of this Agreement.

     Section 18. Benefits of this Agreement.  Nothing in this Agreement shall be
construed  to give to any  person or  corporation  other than the  Company,  the
Warrantholder any legal or

                                      -14-







equitable right,  remedy or claim under this Agreement.  This Agreement shall be
for the sole and exclusive benefit of the Company and the Warrant Holders.

     IN WITNESS  WHEREOF,  the parties  have caused  this  Agreement  to be duly
executed, all as of the date and year first above written.

                                                       Warrant Certificate No. 1


                       Casdim International Systems, Inc.

                            (ORGANIZED UNDER THE LAWS
                            OF THE STATE OF DELAWARE)

                        WARRANTS TO PURCHASE COMMON STOCK

     This certifies that, for value received, Lydford Ltd. (the "Warrantholder")
is the registered  owner of 200,000  warrants (the  "Warrants") to purchase from
Casdim  International  Systems,  Inc.  (the  "Company"),  at any time during the
period commencing at 9:00 a.m., Eastern Time, on May 22, 1997 and ending at 5:00
p.m.,  Eastern Time, on May 21, 2002, at an initial  purchase price per share of
$1.00 (the "Warrant  Price"),  an aggregate of 200,000 shares of Common Stock of
the Company. The Warrants are subject to, and each Warrantholder,  by acceptance
of this  certificate,  consents to all the terms and  provisions  of the Warrant
Agreement dated as of May 22, 1997,  between the Company and the  Warrantholder,
pursuant to which the  Warrants  evidenced  hereby  were  issued  (the  "Warrant
Agreement").

     The  Warrants  evidenced  hereby  may be  exercised  in whole or in part by
presentation  of this Warrant  Certificate  with the  Purchase  Form herein duly
executed  (with a signature  guarantee as provided  therein),  and  simultaneous
payment of the Warrant Price for each Warrant exercised, at the principal office
of the Company. Payment of such price shall be made at the option of each

                                     







Warrantholder in cash or by certified or cashier's check, in next day funds. The
Warrantholder  may  also  receive  Common  Stock  without  any cash  payment  by
presentation of this Warrant  Certificate with the Cashless Exercise Form herein
duly executed (with a signature  guarantee as provided therein) at the principal
office of the Company.

     Upon any partial exercise of the Warrants evidenced hereby,  there shall be
signed and issued to the  Warrantholder  effecting  such partial  exercise a new
Warrant  Certificate  in respect of the  Common  Stock as to which the  Warrants
evidenced hereby shall not have been exercised.  These Warrants may be exchanged
at the office of the Company by surrender of this Warrant  Certificate  properly
endorsed for one or more new Warrants of the same aggregate  number of shares of
Common  Stock  as here  evidenced  by the  Warrant  or  Warrants  exchanged.  No
