and not later than 5:00 P.M. Los Angeles Time, on the Expiration Date,  exercise
this  Warrant  in whole or in part (but not as to a  fractional  share of Common

Purchase  Price.  In order to exercise  this  Warrant,  the holder  hereof shall
deliver  to the  Company  (i) a written  notice  of such  holder's  election  to
exercise this Warrant,  which notice shall be in  substantially  the form of the
Purchase Form appearing at the end of the Warrant  Certificate  attached to this
Warrant as Exhibit A, and (ii)  shall  make  payment of the  aggregate  purchase
price of the shares of Common Stock being purchased,  such payment to be made by
the  delivery  to the  Company  of a  certified  check or checks  payable to the
Company  in an amount  equal to such  Purchase  Price.  The  Company  shall,  as
promptly as practicable, and in any event within 30 days thereafter, execute and
deliver or cause to be executed and delivered, in accordance with said notice, a
certificate  or  certificates  representing  the  aggregate  number of shares of

therein  shall be deemed for all  purposes  to have become a holder of record of
such shares as of the date said notice is received by the Company as  aforesaid.
The  Company  shall  pay all  expenses,  taxes  and  other  charges  payable  in
connection  with the  preparation,  issuance and delivery of stock  certificates
under this Section.

      All shares of Common Stock issued upon the exercise of this Warrant  shall
be validly issued, fully paid and nonassessable.

      B. The Company  shall not be required upon any exercise of this Warrant to
issue a certificate  representing any fraction of a share of Common Stock,  but,
in lieu thereof, shall pay to the holder of this Warrant cash in an amount equal


                                                                     Exhibit 4.4
<PAGE>


to a fraction  corresponding to the fraction of a share involved  (calculated to
the nearest 1/100 of a share) of the current market price of one share of Common
Stock as of the date of receipt by the  Company  of notice of  exercise  of this
Warrant.

      Section 3. TRANSFER, DIVISION AND COMBINATION. This Warrant and all rights
hereunder are transferable.  Any such permitted transfer shall be entered on the
books of the Company to be maintained  for such purpose,  upon surrender of this
Warrant  at  the  principal  office  of the  Company,  together  with a  written
assignment  of this Warrant duly  executed by the holder  hereof or his agent or
attorney and funds  sufficient to pay any stock  transfer taxes payable upon the
making of such  transfer.  Upon such  surrender  and payment  the Company  shall
execute and deliver a new Warrant or Warrants,  dated as of the date of issuance
thereof,  in the name of the  assignee  or  assignees  and in the  denominations
specified in such  instrument of assignment,  and this Warrant shall promptly be
cancelled.

      The Company  shall pay all  expenses,  taxes  (other  than stock  transfer
taxes) and other charges payable in connection with the  preparation,  issue and
delivery of Warrants under this Section.

      The  Company  agrees to  maintain  at it  principal  office  books for the
registration and transfer of the Warrants.

      Section 4. COMPLIANCE WITH SECURITIES ACT; REGISTRATION THEREUNDER.

      A. NO TRANSFER IN VIOLATION OF  SECURITIES  ACT. The holder of the Warrant
agrees not to  transfer  the  related  Warrant  Stock in any manner  which would
result in a violation of the registration  provisions of the Securities Act, and
the  Company  shall not be  required  to take any action  hereunder  which would
result in a violation of such provisions.

      B.  REPRESENTATIONS AND COVENANTS OF THE HOLDER. The Holder represents and
warrants to the Company that the Warrant and the Warrant  Stock will be acquired
by the  Holder for its own  account  for  investment  and not with a view to the
distribution thereof,  except that this sentence shall not be deemed to prohibit
or restrict  transactions not in violation of this Agreement.  As a condition to
transfer  of the  Warrant or  exercise  of it the  Holder  will be  required  to
acknowledge  that this  Warrant  and the Warrant  Stock are being  issued by the
Company without registration under the Securities Act, and may not be offered or
sold unless registered or exempt from registration under the Securities Act. The
Holder will be required to covenant and agree that no Warrants or Warrant  Stock
will be offered or sold by or for the account of the Holder  except (i) pursuant
to an exemption from  registration  under the Securities Act (which exemption is
confirmed in a written opinion of the Holder's counsel  addressed to the Company
and  satisfactory  in form  and  substance  to the  Company's  counsel)  or (ii)
pursuant to an effective  registration  statement under the Securities Act. Each
certificate representing shares shall bear a legend making appropriate reference
to the foregoing restrictions.

      (1)  Unless and until removed as provided below, each Warrant Certificate
           and the certificates evidencing Warrant Stock shall bear a legend in
           substantially the following form:


                                                                     Exhibit 4.4
<PAGE>


           "The Securities have not been registered  under the Securities Act of
           1933,  as  amended,  and  may  not  be  sold,  pledged  or  otherwise
           transferred unless (A) covered by an effective registration statement
           under the Securities Act of 1933, as amended,  (B) in compliance with
           Rule 144 under such Act, or (C) the Company has been  furnished  with
           an opinion of counsel  reasonably  acceptable  to the  Company to the
           effect that no registration is required by such transfer."

      (2)  The Company shall issue a new certificate which does not contain such
           legend if (i) the shares  represented  by such  certificate  are sold
           pursuant to a registration statement (including a current Prospectus)
           which has become and is effective  under the Securities  Act, or (ii)
           the staff of the  Securities  and Exchange  Commission  (or any other
           Federal agency at the time  administering  the  Securities  Act) (the
           "Commission")  shall have  issued a "no  action"  letter,  reasonably
           satisfactory  to counsel  for the  Company,  to the effect  that such
           shares may be freely  sold and  thereafter  traded  publicly  without
           registration under the Securities Act, or (iii) counsel acceptable to
           the  Company  shall  have  rendered  an opinion  satisfactory  to the
           Company  to the  effect  that  such  shares  may be  freely  sold and
           thereafter traded publicly without  registration under the Securities
           Act.

      C.  "PIGGYBACK"  REGISTRATION.  If the  Company,  at any  time  after  the
Commencement  Date  and  prior  to  the  Expiration  Date,  decides  to  file  a
registration  statement  under the  Securities  Act  relating  to any  shares of
Xplorer,  S.A. Common Stock to be offered and sold by the Company pursuant to an
underwriting, (except with respect to registration statements filed with respect
to the issuance of Securities under employee  benefit plans),  the Company shall
give  written  notice to the Holder as  promptly as  possible  for the  proposed
filing of such  registration  statement and will use all  reasonable  efforts to
cause such number of Warrants or Warrant  Stock as the Holder  shall  request in
writing,  within fifteen days after the giving of such notice, to be included in
such registration statement for offering and sale upon the same terms and in the
same  manner as the  Company  proposes  to offer and to sell such  shares of its
Common  Stock  pursuant  thereto;  provided,  that (a) the Company  shall not be
required  to  include  any  Warrant or  Warrant  Stock in any such  registration
statement  if the  Company is advised by its  investment  banking  firm that the
inclusion of such shares may, in such firm's opinion, interfere with the orderly
sale and distribution of the shares of Xplorer,  S.A. Common Stock to be offered
and  sold by the  Company;  and (b) the  Company,  at its sole  discretion,  and
without the consent of the  Holder,  may decide not to file or to withdraw  such
registration statement and may abandon the proposed offering at any time.

      (1)  In  connection  with any  registration  of its shares by the  Company
           hereunder, the Company shall:

           (a)  furnish to sellers and the managing  underwriters such number of
                copies of any prospectus (including any preliminary  prospectus)
                as the  Holder  may  reasonably  request  in order to effect the
                offering and sale of the shares to be offered and sold, but only
                as long as the Company is required under the  provisions  hereof
                to cause the registration statement to remain current;


                                                                     Exhibit 4.4
<PAGE>


           (b)  use its best efforts to qualify  such shares for offering  under
                such  applicable  state  "blue  sky"  laws  as the  sellers  may
                reasonably request;  provided,  however,  that the Company shall
                not be  obligated  to  qualify  as a foreign  corporation  to do
                business under the laws of any  jurisdiction  in which it is not
                then so qualified  or to file any general  consent to service of
                process;

           (c)  instruct   the   transfer   agent  to   reissue  to  the  Holder
                certificates  without legends representing the shares being sold
                in  such  numbers  and   denominations   as  the  sellers  shall
                reasonably request;

           (d)  instruct the transfer  agent (or agents) and the  registrar  (or
                registrars) of the Warrant Stock to release any "stop  transfer"
                order with respect to the shares being sold.

      (2)  The Company,  at its option,  may require that the number of Warrants
           or  Warrant  Stock  offered  for  sale  pursuant  to  a  request  for
           registration under Section 4.C hereof be decreased if, in the opinion
           of the Company's investment banking firm, such reduction is desirable
           in  order  to  permit  the  orderly  distribution  and  sale  of  the
           securities  being  offered  thereunder.  If the Company shall require
           such a reduction,  the Holder  shall have the right to withdraw  from
           the offering.

      (3)  In connection  with any  registration  statement in which Warrants or
           the Warrant  Stock are included  pursuant to Section 4.C hereof,  the
           Company will pay all Commission and "blue sky" registration and other
           necessary  filing  fees,  underwriting  discounts,   commissions  and
           expenses,  printing expenses, fees and disbursements of legal counsel
           for  the  Company  and  "blue  sky"  counsel,  transfer  agents'  and
           registrars'  fees,  fees and  disbursements  of  experts  used by the
           Company in connection with such registration, and expenses incidental
           to any post-effective  amendment to such registration statement.  The
           Holder/Seller shall pay all other expenses  attributable to inclusion
           in the offering of Warrants or the Warrant Stock, including,  without
           limitation,   Commission  and  "blue  sky"   registration  and  other
           necessary  filing fees and  underwriting  discounts,  commissions and
           expenses  attributable  thereto  and  fees and  disbursements  of the
           Holder/Seller's counsel, accountants and experts, if any.

      (4)  In the case of each  registration  of shares  effected by the Company
           pursuant to Section 4.C hereof,  the Company  will agree to indemnify
           and hold harmless each Seller of Warrants or of Warrant Stock and its
           controlling  persons against any and all losses,  claims,  damages or
           liabilities to which they or any of them may become subject under the
           Securities  Act or any other  statute  or common law  (including  any
           amount paid in settlement of any litigation, commenced or threatened,
           if such  settlement is effected with the written  consent of Xplorer,
           S.A., and to reimburse them for any legal or other expenses  incurred
           by them in connection with investigating any claims and defending any
           actions, insofar as any such losses, claims, damages,  liabilities or
           actions  arise out of or are based upon (a) any untrue  statement  or


                                                                     Exhibit 4.4
<PAGE>


           alleged  untrue  statement  of  a  material  fact  contained  in  the
           registration   statement   relating  to  such   Securities,   or  any
           post-effective  amendment thereto or the omission or alleged omission
           to state  therein a material  fact  required to be stated  therein or
           necessary  to make the  statements  therein not  misleading,  (b) any
           untrue  statement  or alleged  untrue  statement  of a material  fact
           contained in any preliminary  prospectus relating to such Securities,
           if sued prior to the effective date of such  registration  statement,
           or contained in the final prospectus  relating to such Securities (as
           amended  or  supplement  if the  Company  shall  have  filed with the
           Commission any amendment  thereof or supplement  thereto);  provided,
           however, that the indemnification agreement contained in this Section
           4.C shall not (a) apply to any losses, claims,  damages,  liabilities
           or actions  arising out of, or based upon, any such untrue  statement
           or  alleged  untrue  statement,  or  any  such  omission  or  alleged
           omission,  which was made in  reliance  upon and in  conformity  with
           information   furnished   to  the  Company  by  the  seller  or  such
           underwriter for used in connection with the  registration  statement,
           any  preliminary  prospectus  or final  prospectus  contained in such
           registration  statement,  or any amendment or supplement  thereto, or
           (b) inure to the benefit of any underwriter or any person controlling
           such underwriter,  if such underwriter  failed to send or give a copy
           of the final prospectus to the person asserting the claim at or prior
           to the written  confirmation  of the sale of such  securities to such
           person and if the untrue  statement  or omission,  or alleged  untrue
           statement  or  omission,  in  question  was  corrected  in such final
           prospectus.

      (5)  In  case of each  registration  of  shares  effected  by the  Company
           pursuant to Section 4.C hereof,  the Seller and each  underwriter  of
           shares will  agree,  in the same manner and to the same extent as set
           forth in Section  4.C  above,  to  indemnify  and hold  harmless  the
           Company,  each person (if any) who  controls  the Company  within the
           meaning of Section 15 of the  Securities  Act,  the  directors of the
           Company  and those  officers of the Company who shall have signed any
           such registration statement,  with respect to any untrue statement or
           alleged  untrue  statement in, or omission or alleged  omission from,
           such registration  statement or any post-effective  amendment thereto
           or any  preliminary  prospectus  or final  prospectus  (as amended or
           supplemented,   if  amended  or   supplemented)   contained  in  such
           registration  statement,  which  was  made in  reliance  upon  and in
           conformity with information furnished to the Company by the Seller or
           any  underwriter   for  use  in  connection  with  the   registration
           statement,  any preliminary  prospectus or final prospectus contained
           in  such  registration  statement,  or any  amendment  or  supplement
           thereto.

      (6)  Each indemnified  party under Section 4.C(4) or Section 4.C(5) hereof
           will, with reasonable  promptness after its receipt of written notice
           of the commencement of any action against such  indemnified  party in
           respect of which indemnity may be sought from an  indemnifying  party
           on account of an indemnity  agreement  contained in Section 4.C(4) or
           4.C(5)  hereof,  notify  the  indemnifying  party in  writing  of the
           commencement  thereof,  the  indemnifying  party will be  entitled to


                                                                     Exhibit 4.4
<PAGE>


           participate  therein and to the extent it may wish,  jointly with any
           other  indemnifying party similarly  notified,  to assume the defense
           thereof with counsel  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, the indemnifying party
           will not be liable to such indemnified  party under Section 4.C(4) or
           4.C(5) hereof for any legal or other expenses  subsequently  incurred
           by such  indemnified  party in  connection  with the defense  thereof
           other  than  reasonable   costs  of   investigation.   The  indemnity
           agreements in Sections  4.C(4) and 4.C(5) hereof shall be in addition
           to any liabilities  which the indemnifying  parties may have pursuant
           to law.

      (7)  In addition to the rights above-provided,  the Company will cooperate
           with the then Holders of the  Securities in preparing and signing any
           registration  statement  in  addition to the  registration  statement
           discussed above, required in order to sell or transfer the Securities
           and  will  supply  all  information  required  therefore,   but  such
           additional  registration  statement  shall  be at the  then  Holders'
           expense,  unless the Company elects to register or qualify additional
           shares of the  Company's  Common  Stock,  in which  case the cost and
           expense of such registration  statement will be pro-rated between the
           Company  and the Holders of the  Securities  to the  aggregate  sales
           price of all the securities being issued.


      Section 5.  ADJUSTMENTS.  The number of shares of Warrant  Stock  shall be
subject to adjustment from time to time as follows:

      A.  ADJUSTMENT OF EXERCISE  PRICE IN THE EVENT OF STOCK  DIVIDENDS,  STOCK
SPLITS AND  REVERSE  STOCK  SPLITS.  Anything  in this  Section to the  contrary
notwithstanding,  in case the Company  shall at any time issue  Common  Stock or
Convertible  Securities by way of dividend or other distribution on any stock of
the  Company or effect a stock split or reverse  stock split of the  outstanding
shares of Common Stock, the Exercise Price shall be proportionately decreased in
the case of such stock split or  increased  in the case of such  reversed  stock
split (on the date that such stock split or reverse  stock  split  shall  become
effective), by multiplying the Exercise Price in effect immediately prior to the
stock dividend,  stock split or reverse stock split by a fraction, the numerator
of which is the number of shares of Common Stock  outstanding  immediately prior
to such stock dividend,  stock split or reverse stock split, and the denominator
of which is the number of shares of Common Stock  outstanding  immediately after
such stock dividend, stock split or reverse stock split.

      B. NO  ADJUSTMENT  FOR SMALL  AMOUNTS.  Anything  in this  Section  to the
contrary  notwithstanding,  the Company  shall not be required to give effect to
any  adjustment in the Exercise  Price unless and until the net effect of one or
more adjustments,  determined as above provided, shall have required a change of
the Exercise  Price by at least ten cents ($.10),  but when the  cumulative  net
effect of more than one  adjustment so determined  shall be to change the actual
Exercise Price by at least ten cents ($0.10),  such change in the Exercise Price
shall thereupon be given effect.


                                                                     Exhibit 4.4

      C. NUMBER OF SHARES  ADJUSTED.  Upon any adjustment of the Exercise Price,
the Holder  shall  thereafter  (until  another such  adjustment)  be entitled to
purchase,  at the new Exercise  Price,  the number of shares,  calculated to the
nearest  full  share,  obtained by  multiplying  the number of shares of Warrant
Stock  initially  issuable  upon exercise of any of the Warrants by the Exercise
Price in effect on the date hereof and  dividing  the product so obtained by the
new Exercise Price.

      D. STATEMENT ON WARRANTS.  Irrespective of any adjustments in the Exercise
Price or the  number  of kind of shares  purchasable  upon the  exercise  of the
Warrants, the Warrant Certificates theretofore or thereafter issued may continue
to  express  the same  price and  number and kind of shares as are stated in the
Warrants initially issuable pursuant to this Agreement.


      Section 6. OFFICER'S CERTIFICATE

      Whenever the Exercise Price shall be adjusted as required by the provision
of Section 5 hereof,  the  Company  shall  forthwith  file in the custody of its
Secretary  or an  Assistant  Secretary  at its  principal  office,  an officer's
certificate  showing the adjusted  Exercise Price  determined as herein provided
and setting forth in reasonable detail the facts requiring such adjustment. Each
such officer's  certificate  shall be made available at all reasonable times for
inspection  by the  Holders  and the Company  shall,  forthwith  after each such
adjustment,  deliver a copy of such  certificate  to each of the  Holders.  Such
certificate shall be conclusive as to the correctness of such adjustment.


      Section 7. NOTICES TO WARRANTHOLDERS

      So long as any Warrant shall be  outstanding  and  unexercised  (a) if the
Company shall pay any dividend or make any distribution upon the Common Stock or
(b) if the Company  shall offer to the holders of Common Stock for  subscription
or purchase by them any shares of stock of any class or any other  rights or (c)
if any capital  reorganization of the Company,  reclassification  of the capital
stock of the  Company,  consolidation  or  merger  of the  Company  with or into
another corporation,  sale, lease or transfer of all or substantially all of the
property  and assets of the  Company to another  corporation,  or  voluntary  or
involuntary  dissolution,  liquidation  or  winding up of the  Company  shall be
effected, then, in any such case, the Company shall cause to be delivered to the
Holders,  at least 30 days prior to the date specified in (i) or (ii) below,  as
the case may be, a notice  containing a brief description of the proposed action
and  stating  the date on which (i) a record is to be taken for the  purpose  of
such  dividend,   distribution  or  rights,   or  (ii)  such   reclassification,
reorganization,   consolidation,   merger,   conveyance,   lease,   dissolution,
liquidation or winding up is to take place and the date, if any, as of which the
holders of Common Stock of record shall be entitled to exchange  their shares of
Common Stock for securities or other property deliverable upon reclassification,
reorganization,  consolidation,  merger, conveyance, dissolution, liquidation or
winding up.


                                                                     Exhibit 4.4

      Section 8.  CLOSING OF TRANSFER  BOOKS.  The Company  will not at any time
(except on  dissolution,  liquidation  or winding up of the  Company)  close its
transfer  books  against the  transfer of any shares of Common  Stock  issued or
issuable  upon exercise of the Warrant in any manner which  interferes  with the
timely exercise of the Warrant.


      Section 9. TRANSFER OF WARRANT; WARRANT LEDGER.

      A. Subject to the provisions of this Agreement, the Warrant and all rights
hereunder  are  transferable,  in whole or in part  (but not as to a  fractional
share of Common Stock),  by written  assignment with  appropriate  notice to the
Company of any such transfer.

      B. The  Company  shall at all  times  maintain  a  ledger  indicating  the
ownership  of the Warrant  and the number of shares of Common  Stock as to which
the Warrant  has been  exercised  and the date of such  exercise  (the  "Warrant
Ledger"). Upon any transfer of any interest in the Warrant by the Holder or by a
transferee  of the Holder as provided in this  Section 9, the Company  shall (i)
note such transfer on the Warrant  Ledger,  (ii) issue and deliver a new Warrant
Certificate   (substantially   in  the  form  of   Exhibit  A  with  the  blanks
appropriately  completed)  evidencing such transferee's  interest in the Warrant
and  (iii) if the  Warrant  Certificate  surrendered  in  connection  with  such
transfer  evidenced  the right to  acquire a greater  number of shares of Common
Stock than the interest which was transferred,  issue a new Warrant  Certificate
(substantially in the form of Exhibit A with the blanks appropriately completed)
evidencing   the  right  to  acquire  shares  of  Common  Stock  which  was  not
transferred.


      Section 10. PAYMENT OF TAXES.  The Company will pay all documentary  stamp
taxes,  if any,  attributable  to the initial  issuance of the shares of Warrant
Stock upon the exercise of Warrants;  provided,  however, that the Company shall
not be  required  to pay any tax or taxes which may be payable in respect of any
transfer  involved in the issue or delivery of the Warrant  Certificates  or the
certificates  for the shares of  Warrant  Stock in a name other than that of the
registered  Warrantholder in respect of which such Warrants or shares of Warrant
Stock are issued.


      Section 11. MUTILATED OR MISSING WARRANT CERTIFICATES. In case any Warrant
Certificate shall be mutilated, lost, stolen or destroyed, the Company shall, at
the request of the holder of such  certificate,  issue and deliver,  in exchange
and  substitution  for and upon  cancellation  of the mutilated  certificate  or
certificates,  or in lieu of a 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 such loss, theft or destruction of such
Warrant  Certificate  or  Certificates,   and  indemnity,  if  requested,   also
satisfactory  (as to form and amount) to the Company.  An application for such a
substitute Warrant Certificate or Certificates shall also comply with such other
reasonable  regulations and pay such other reasonable charges as the Company may
prescribe.


                                                                     Exhibit 4.4

      Section  12.  RESERVATION  OF  SHARES  OF  WARRANT  STOCK.  There has been
reserved, and the Company shall at all times keep reserved so long as any of the
Warrants  remain  outstanding,  out of its  authorized  Common Stock a number of
shares of Common Stock  sufficient  to provide for the exercise of the rights of
purchase  represented by the  outstanding  Warrants.  The transfer agent for the
Common Stock and every subsequent transfer agent for any shares of the Company's
capital  stock  issuable  upon the  exercise  of any of the  rights of  purchase
aforesaid  will be  irrevocably  authorized and directed at all times to reserve
such number of authorized  as shall be requisite  for such purpose.  The Company
will  keep a copy of this  Agreement  on file  with the  transfer  agent for any
shares of the Company's  capital stock  issuable upon the exercise of the rights
of purchase  represented by the Warrants.  The Company will supply such transfer
agent with duly executed stock certificates for such purpose and will provide or
otherwise make available any cash which may be payable as provided in Section 13
hereof. All Warrant  Certificates  surrendered in exercise of the rights thereby
evidenced shall be cancelled by the Company.


      Section 13. FRACTIONAL SHARES.

      No  fractional  shares or scrip  representing  fractional  shares shall be
issued upon the  exercise of the  Warrants.  With  respect to any  fraction of a
share called for upon the exercise of any Warrant,  the Company shall pay to the
Warrantholder an amount in cash equal to such fraction multiplied by the current
market value of such fractional share, determined as follows:

           (i) If the Common Stock is listed on a national  securities  exchange
      or admitted to unlisted trading  privileges on such exchange,  the current
      value shall be the last  reported  sale price of the Common  Stock on such
      exchange  on the last  business  day prior to the date of  exercise of the
      Warrant or if no such sale is made on such day,  the  average  closing bid
      and asked prices for such day on such exchange; or

           (ii) If the Common  Stock is not so listed or  admitted  to  unlisted
      trading  privileges,  the  current  value  shall  be the  mean of the last
      reported bid and asked  prices  reported by the  National  Association  or
      Securities Dealers Quotation System  ("NASDAQ"),  (or, if not so quoted by
      NASDAQ, by the National  Quotation Bureau,  Inc.) on the last business day
      prior to the date of the exercise of the Warrant; or

           (iii) If the Common  Stock is not so listed or  admitted  to unlisted
      trading  privileges  and bid and asked  prices  are not so  reported,  the
      current value shall be an amount, not less than the book value, determined
      in such  reasonable  manner as may be prescribed by the board of directors
      of  the  Company,  such  determination  to be  final  and  binding  on the
      Warrantholder.


      Section 14. APPLICABLE LAW.

      This  Agreement and each Warrant  Certificate  issued  hereunder  shall be
deemed to be a contract made under the laws of the State of  California  and for
all purposes shall be construed in accordance with the laws of said state.


                                                                     Exhibit 4.4
