                  duly executed and accompanied by payment of the Exercise Price

                  certificates representing such Option Shares shall not then be
                  actually delivered to the Optionee.

                           (b) Payment of Exercise  Price.  Except as  otherwise
                  provided  below,  payment of the aggregate  Exercise Price for

                  shall be made (i) in cash, by check, or cash equivalent,  (ii)
                  by tender to the Company, or attestation to the ownership,  of
                  whole Shares owned by the Optionee  having a fair market value
                  (as   determined  by  the  Company   without   regard  to  any
                  restrictions on  transferability  applicable to such Shares by
                  reason of federal or state  securities laws or agreements with
                  an  underwriter  for the Company) not less than the  aggregate
                  Exercise  Price,  (iii) by means of a  Cashless  Exercise,  as
                  defined in Section 4(c)(ii), or (iv) by any combination of the
                  foregoing.

                           (c) Limitations on Forms of Consideration.

                                    (i)  Tender of Shares.  Notwithstanding  the
                           foregoing,  the Option may not be exercised by tender
                           to the Company,  or attestation to the ownership,  of
                           Shares to the extent such tender,  or  attestation to
                           the ownership, of Shares would constitute a violation
                           of the provisions of any law, regulation or agreement
                           restricting  the redemption of the Company's  Shares.
                           (The  Option  may not be  exercised  by tender to the
                           Company,  or attestation to the ownership,  of Shares
                           unless  such Shares  beneficially  have been owned by
                           the Optionee for more than six (6) months).

                                    (ii)   Cashless   Exercise.    A   "Cashless
                           Exercise"  means the assignment in a form  acceptable
                           to the Company of the proceeds of a sale or loan with
                           respect  to some or all of the Shares  acquired  upon
                           the  exercise of the Option  pursuant to a program or
                           procedure approved by the Company (including, without
                           limitation,  through an exercise  complying  with the
                           provisions of Regulation T as  promulgated  from time
                           to time by the  Board  of  Governors  of the  Federal
                           Reserve System). The Company reserves, at any and all
                           times,  the right, in the Company's sole and absolute
                           discretion,  to decline to approve or  terminate  any
                           such  program or  procedure.  Generally,  and without
                           limiting  the  Company's   absolute   discretion,   a
                           Cashless  Exercise  will  only be  permitted  at such
                           times during which the Shares  underlying this Option
                           are publicly traded.

                           (d) Undertaking With Respect to Tax  Obligations.  At
                  the time of exercise of this Option,  in whole or in part,  or
                  at any time  thereafter as requested by the  Corporation,  the
                  Optionee shall undertake to be responsible  for, to pay any to
                  hold the Corporation harmless from and against any liabilities
                  for any sums  required to satisfy any  federal,  state,  local
                  and/or   foreign  tax   obligations   (including   withholding
                  obligations, if any) arising upon the exercise, in whole or in
                  part, of this Option,  the transfer,  in whole or in party, of
                  any  Shares  acquired  upon  exercise  of this  Option  or the
                  operation of any law or  regulation  applicable to this Option
                  or the exercise thereof, in whole or in part. Such undertaking
                  by  the  Option  shall  be  in  writing  in  form   reasonably
                  satisfactory  to the Corporation and shall be submitted by the
                  Optionee  to the  Corporation  at such  time  as the  Optionee
                  exercises this Option, in whole or in part.

                           (e)   Condition   to   Grant   and    Exercisability.
                  Notwithstanding  anything contained herein to the contrary, in
                  order  to  satisfy  certain   relevant  legal  and  regulatory
                  requirements,  the grant and vesting of this  Option  shall be
                  subject  to  ratification  and  approval  by the  holders of a
                  majority of the Corporation's then outstanding  Shares, and if
                  the  holders  of  such  majority  of  the  Corporation's  then
                  outstanding Shares do not ratify and approve the grant of this
                  Option at the next Annual or Special  Meeting of  Shareholders
                  of the  Corporation  within  twelve (12) months after the date
                  hereof,   the  Options  granted  hereby  shall   automatically
                  terminate,  be canceled  in their  entirety  and the  Optionee
                  shall  forfeit all rights with  respect  thereto or  otherwise
                  under this  Agreement  and this Option  shall be of no further
                  force of effect.  Prior to  ratification  and  approval by the
                  Corporation's   Shareholders  as  hereinabove  provided,  this
                  Option shall not be exercisable, in whole or in part.

         SECTION 5. EXCHANGE OR LOSS OF OPTION.

                           (a) This Option is exchangeable,  without expense, at
                  the option of the Optionee,  upon  presentation  and surrender
                  hereof to the Corporation at its principal  office,  or at the
                  office of its stock transfer  agent, if any, for other Options
                  of different denominations entitling the Optionee to purchase,
                  in the  aggregate,  the  same  number  of  Shares  purchasable
                  hereunder.

                           (b) Upon receipt by the  Corporation  of an affidavit
                  of loss which shall  constitute  evidence  satisfactory to the
                  Corporation of the loss, theft, destruction,  or mutilation of
                  this Option and (in the case of loss,  theft,  or destruction)
                  of reasonably satisfactory  indemnification,  and (in the case
                  of mutilation) upon surrender and cancellation of this Option,
                  the Corporation  will execute and deliver a new Option,  which
                  shall constitute an additional  contractual  obligation on the
                  part of the  Corporation,  whether or not this Option so lost,
                  stolen,   destroyed,   or  mutilated  shall  be  at  any  time
                  enforceable by anyone.

         SECTION 6. NON-TRANSFER AND TERMINATION OF THE OPTION.

<PAGE>

                           (a)  Nontransferability of the Option. The Option may
                  be exercised  during the lifetime of the Optionee  only by the
                  Optionee or the  Optionee's  guardian or legal  representative
                  and may not be assigned or transferred in any manner except by
                  will or by the laws of descent and distribution. Following the
                  death of the Optionee,  the Option,  to the extent provided in
                  Section  6(c),  may  be  exercised  by  the  Optionee's  legal
                  representative  or by any person  empowered to do so under the
                  deceased  Optionee's will or under the then applicable laws of
                  descent and distribution.

                           (b)  Termination  of the  Option.  The  Option  shall
                  terminate  and may no longer  be  exercised  after the  Option
                  Termination Date.

         SECTION  7.  RIGHTS OF THE  OPTIONEE.  Except as  provided  in the last
         sentence of Section 1, the  Optionee  shall not, by virtue  hereof,  be
         entitled to any rights as a shareholder in the  Corporation,  either at
         law or  equity.  The  rights  of the  Optionee  are  limited  to  those
         expressed  in  this  Option  and  are  not   enforceable   against  the
         Corporation except to the extent set forth herein.

         SECTION 8. ANTI-DILUTION PROVISIONS.  The number and kind of securities
         purchasable  upon the  exercise of this Option and the  Exercise  Price
         shall be subject to adjustment from time to time as follows:

                           (a)   Reclassification   of   Shares.   In  case  the
                  Corporation shall (i) pay a dividend or make a distribution on
                  the outstanding  Shares payable in Shares,  (ii) subdivide the
                  outstanding  Shares  into a greater  number of  Shares,  (iii)
                  combine the outstanding Shares into a lesser number of Shares,
                  or  (iv)  issue  by  reclassification  of  the  Shares  of the
                  Corporation,  the Optionee of this Option shall  thereafter be
                  entitled,  upon  exercise,  to receive  the number and kind of
                  Shares which,  if this Option had been  exercised  immediately
                  prior to the happening of such event,  the Optionee would have
                  owned upon such  exercise  and been  entitled to receive  upon
                  such  dividend,  distribution,  subdivision,  combination,  or
                  reclassification.  Such adjustment  shall become  effective on
                  the day next following (x) the record date of such dividend or
                  distribution  or (y)  the day  upon  which  such  subdivision,
                  combination, or reclassification shall become effective.

                           (b) Consolidation,  Merger or Sale of the Corporation
                  or its Assets.  In case the Corporation  shall  consolidate or
                  merge  into  or  with  another  corporation,  or in  case  the
                  Corporation  shall  sell or  convey  to any  other  person  or
                  persons  all  or   substantially   all  the  property  of  the
                  Corporation,  the Optionee shall thereafter be entitled,  upon
                  exercise,  to receive  the kind and  amount of common  shares,
                  other  securities,  cash,  and property  receivable  upon such
                  consolidation,  merger, sale, or conveyance by a holder of the
                  number of Common Shares which might have been  purchased  upon
                  exercise   of   this   Option   immediately   prior   to  such
                  consolidation,  merger, sale, or conveyance, and shall have no
                  other  conversion   rights.  In  any  such  event,   effective
                  provision  shall be made,  in the  certificate  or articles of
                  incorporation  of the resulting or surviving  corporation,  in
                  any contracts of sale and conveyance, or otherwise so that, so
                  far as  appropriate  and as nearly as  reasonably  may be, the
                  provisions  set forth herein for the  protection of the rights
                  of the  Optionee  of  this

<PAGE>

                  Option shall thereafter be made applicable.

                           (c) Adjustment of Exercise Price. Whenever the number
                  of Shares purchasable upon exercise of this Option is adjusted
                  pursuant to this Section 8, the Exercise Price per Share shall
                  be adjusted  simultaneously by multiplying that Exercise Price
                  per Share in effect  immediately prior to such adjustment by a
                  fraction, of which the numerator shall be the number of Shares
                  purchasable upon exercise of this Option  immediately prior to
                  such  adjustment,  and of which the  denominator  shall be the
                  number  of  Shares  so  purchasable   immediately  after  such
                  adjustment,  so that  the  aggregate  exercise  price  of this
                  Option remains the same.

                           (d) Fractional Shares. No adjustment in the number of
                  Shares  which may be  purchased  upon  exercise of this Option
                  shall be required  unless  such  adjustment  would  require an
                  increase or decrease of more than .50 of a share in the number
                  of the Shares  which may be so  purchased  provided,  however,
                  that any  adjustment  which by reason of this  Section 8(d) is
                  not required to be made shall be carried forward  cumulatively
                  and taken into  account  in any  subsequent  calculation.  All
                  calculations under this Section 8 shall be made to the nearest
                  cent or to the nearest  one-hundredth  of a share, as the case
                  may be.

                           (e) Distributions.  In the event that at any time, as
                  a result of an adjustment made pursuant to this Section 8, the
                  Optionee  shall become  entitled to receive  upon  exercise of
                  this Option cash,  property,  or securities other than Shares,
                  then references to Shares in this Section 8 shall be deemed to
                  apply,  so far as appropriate and as nearly as may be, to such
                  cash, property, or other securities.

                           (f) Form of Options.  Irrespective of any adjustments
                  in the  Exercise  Price  or in the  number  or kind of  Shares
                  purchasable upon exercise of this Option,  the form of Options
                  theretofore  or thereafter  issued may continue to express the
                  same price and number and kind of Shares as are stated in this
                  Option.

         SECTION  9.  OFFICER'S  CERTIFICATE.  Whenever  the  number  or kind of
         securities  purchasable  upon  exercise of this Option or the  Exercise
         Price shall be adjusted as required by the provisions of Section 8, the
         Corporation  shall  forthwith  file  with its  Secretary  or  Assistant
         Secretary at its principal office and with its stock transfer agent, if
         any, an officer's  certificate  showing the adjusted number and kind of
         securities  purchasable  upon  exercise of this Option and the adjusted
         Exercise  Price  determined  as herein  provided  and setting  forth in
         reasonable  detail such facts as shall be  necessary to show the reason
         for and the manner of computing such  adjustments.  Each such officer's
         certificate  shall  be  made  available  at all  reasonable  times  for
         inspection by the Optionee and the Corporation  shall,  forthwith after
         each such adjustment, mail by certified mail a copy of such certificate
         to the Optionee.

         SECTION  10.  NOTICES  TO  OPTIONEE.  So long as this  Option  shall be
         outstanding,  if the Corporation  shall propose to take any action that
         would  cause  an  adjustment  to be made  pursuant  to  Section  8, the
         Corporation shall mail by certified mail to the Optionee, before, or no
         later than 15 days after, the day on which such adjustment would become
         effective,  a notice  setting forth in reasonable  detail the action so
         taken.

         SECTION  11. (A)  RESTRICTIONS  ON GRANT OF THE OPTION AND  ISSUANCE OF
         SHARES.  The  grant

<PAGE>

         of the Option and the  issuance of Shares  upon  exercise of the Option
         shall be subject to  compliance  with all  applicable  requirements  of
         federal,  state or foreign  law with  respect to such  securities.  The
         Option may not be  exercised  if the  issuance of Shares upon  exercise
         would  constitute  a  violation  of any  applicable  federal,  state or
         foreign securities laws or other law or regulations or the requirements
         of any stock  exchange or market  system upon which the Shares may then
         be listed.  In addition,  the Option may not be exercised  unless (i) a
         registration  statement  under the  Securities Act shall at the time of
         exercise of the Option be in effect with respect to the Shares issuable
         upon  exercise of the Option or (ii) in the opinion of legal counsel to
         the Company,  the Shares  issuable  upon  exercise of the Option may be
         issued in accordance with the terms of an applicable exemption from the
         registration  requirements  of the  Securities  Act.  THE  OPTIONEE  IS
         CAUTIONED  THAT THE OPTION MAY NOT BE  EXERCISED  UNLESS THE  FOREGOING
         CONDITIONS ARE SATISFIED.  ACCORDINGLY, THE OPTIONEE MAY NOT BE ABLE TO
         EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED.  The
         inability  of the  Company to obtain  from any  regulatory  body having
         jurisdiction  the  authority,  if any,  deemed by the  Company's  legal
         counsel to be necessary  to the lawful  issuance and sale of any Shares
         subject to the Option  shall  relieve the Company of any  liability  in
         respect of the  failure  to issue or sell such  Shares as to which such
         requisite authority shall not have been obtained. As a condition to the
         exercise of the Option, the Company may require the Optionee to satisfy
         any  qualifications  that may be necessary or appropriate,  to evidence
         compliance  with  any  applicable  law or  regulation  and to make  any
         representation  or warranty with respect thereto as may be requested by
         the Company.

                       (B)  It is  intended  that  this  Option  and  all of the
         Underlying Shares shall be included in the Corporation's  existing Form
         S-8  Registration  Statement  or if  not so  included,  such  Form  S-8
         Registration Statement is to be amended for that purpose (or a separate
         Form S-8 Registration  Statement (or its successor Form) is to be filed
         by the  Corporation) and rendered under the Securities Act by not later
         than  three  business  days after the date of  convening  the Annual or

                                SPATIALIGHT, INC.

                  TIME ACCELERATED RESTRICTED STOCK AWARD PLAN

                                   ("TARSAP")

TARSAP (this  "Agreement" or the "Option  Agreement")  made as of the 7th day of
July,   2003   between   SPATIALIGHT,   INC.,  a  New  York   corporation   (the
"Corporation"),  whose  principal  place of  business  is  located at 5 Hamilton
Landing,  Suite 100,  Novato,  California  94949,  and  Theodore H. Banzhaf (the
"Optionee") whose principal residence is located at 1801 Gough Street #403 , San
Francisco, CA 94109

                                    Preamble

         The Corporation and Optionee have entered into an Employment  Agreement
effective as of the date of this Agreement (the  "Effective  Date")  pursuant to
which  Optionee  will serve as the  Corporation's  Executive  Vice  President of
Strategic   Planning  upon  the  terms  set  forth   therein  (the   "Employment
Agreement").  As a material  inducement  for Optionee to become  employed as the
Corporation's  Executive Vice President of Strategic  Planning,  the Corporation
has agreed to grant  Optionee  options to purchase its Common  Shares,  $.01 par
value per share  (the  "Shares")  subject  to the terms and  conditions  of this
Agreement.

         1.       Grant of Options.

                  (a) Upon the terms and subject to the  conditions  hereinafter
         set forth, the Corporation  hereby grants to the Optionee the right and
         option  to  purchase  from the  Corporation  a total  of Eight  Hundred
         Thousand  (800,000)  Shares of the  Corporation  at an exercise  (i.e.,
         purchase)  price  determined by the provisions of Section 6 hereof (the
         "Options"). The Options granted hereby shall be exercisable as provided
         in  Sections 2 and 3 hereof  unless  terminated  at an earlier  date in
         accordance  with the  terms of this  Agreement.  If the  Options  shall
         terminate for any reason  without  having been  exercised in full,  the
         Corporation may use any then remaining  unpurchased Shares reserved for
         the grant of options to any other  employee  or party  selected  by the
         Board of Directors of the  Corporation  (the  "Board") or for any other
         appropriate  corporate purpose, as determined in the sole discretion of
         the Board.  The  Options  shall  become  exercisable  immediately  upon
         vesting.

                  (b) The Options  granted by this  Agreement are not, and shall
         not be deemed, to have been granted under the Corporation's  1999 Stock
         Option Plan (the "1999 Plan"),  the  Corporation's  1993  Non-Statutory
         Stock  Option Plan (the "1993  Plan") or any other stock option plan of
         the  Corporation  in effect as of the date hereof or hereafter  adopted
         (the "Other Plans"), and the number of Shares which may be reserved for
         the  Optionee's  exercise of the Options  granted  hereunder  shall not
         reduce the number of Shares reserved under the 1999 Plan, the 1993 Plan
         or any Other  Plans and,  in the event the  Options  granted  hereunder
         shall  terminate for any reason  without having been exercised in full,
         none of any then  remaining  unpurchased  Shares subject to the Options
         shall  increase the total  number of Shares then  reserved for purchase
         under  the  1999  Plan,  the  1993  Plan  or  any  Other  Plan  of  the
         Corporation.

                  (c) It is intended both by the  Corporation  and Optionee that
         the Options granted hereby shall be Non-Statutory Stock Options.

         2.       Exercise of Option.

                  (a) Subject to the  limitations  set forth in this  Agreement,
         the Optionee may  exercise  the  Options,  in whole or in part,  to the
         extent  then   exercisable  in  accordance  with  this  Agreement,   by
         forwarding to the  Corporation  written  notice  stating the Optionee's
         election  of such  exercise  right and

<PAGE>

         specifying  the number of whole Shares to be purchased,  accompanied by
         the  Optionee's  payment in full of the  aggregate  option price of the
         Shares being purchased in cash, by check,  or, in the discretion of the
         Board,  by the delivery of Shares  (such Shares to be credited  against
         the option  price in an amount  equal to their  aggregate  Fair  Market
         Value as defined in Section 13 hereof on the date of  exercise)  or any
         combination  thereof  ("Notice of  Exercise").  The  Optionee  shall be
         responsible  for and shall pay to the  Corporation  all withholding and
         other  similar taxes which may be payable by the Optionee upon exercise
         of the Options, if applicable.

                  (b) As soon as practicable after receipt by the Corporation of
         the Notice of Exercise and of full  payment of the  exercise  price for
         all Shares with  respect to which the Options  are being  exercised,  a
         certificate or certificates  representing the purchased Shares shall be
         registered  in the  records  of the  Corporation  in  the  name  of the
         Optionee or his successor and shall be delivered to the Optionee or his
         successor at the Optionee's address shown in the payroll records of the
         Corporation or at such other address as may be designated in writing by
         the Optionee in the Optionee's Notice of Exercise. Neither the Optionee
         nor his  successor or legal  representative  shall have any rights as a
         shareholder of the  Corporation in respect of any Shares  issuable upon
         the  exercise  of this  Option  prior  to the  record  date as of which
         certificates  for such Shares shall have been issued by the Corporation
         as hereinabove provided.

                  (c) Unless the Options are  terminated  earlier in  accordance
         with the terms  hereof,  the  Options and all rights  thereunder  shall
         expire  on,  and may no  longer be  exercised  after,  the third  (3rd)
         anniversary   after  each  of  the  respective  dates  upon  which  the
         percentages of the Options to purchase the number of Shares  designated
         herein  have  vested  and become  exercisable  in  accordance  with the
         provisions of Section 3.

                                    under Section 3(b)(i) above, or in the event
                                    that the  Shares  achieve

                                    the Fair  Market  Value  test  set  forth in
                                    Section  3(b)(iii)  above before  satisfying
                                    the Fair  Market  Value test  under  Section
                                    3(b)(ii),  then the Options to purchase  the

                                    cumulatively  at  the  respective   exercise
                                    prices  set  forth  in   Sections   3(b)(i),
                                    3(b)(ii) and/or  3(b)(iii),  as the case may
                                    be; and

                                    (B)  As  used  in  this  Section  3(b),  for
                                    purposes  of  determining  the  twenty  (20)
                                    trading days comprising the FMV Period,  any
                                    business  day upon which  there  shall be no
                                    trading  in the  Shares  of the  Corporation
                                    shall not be counted.

                  (c) In no event  shall any of the  Options  granted  hereunder
         vest and be  exercisable  unless the  Optionee  is an  Employee  of the
         Corporation  or any of its  Subsidiaries  on  any  such  vesting  date;
         provided, however, in the event the Employee's employment is terminated
         by the Corporation or any of its Subsidiaries without Cause pursuant to
         Section  2(b)(iv) of the Employment  Agreement,  the Options shall vest
         and be exercisable to the extent any of the performance tests set forth
         in Section 3(b)(i) through (iii),  inclusive,  are satisfied during the
         ninety (90) day period  immediately  succeeding the date of termination
         of his employment.

                  (d)  Notwithstanding any of the provisions of Sections 3(a) or
         (b), none of the Options granted hereunder, including any Options which
         have vested and therefore  become  exercisable,  may be exercised until
         the shareholders of the Corporation  shall, if required by New York law
         or the  regulations of any exchange or  inter-dealer  system upon which
         the  Company's  Shares will be listed or in which such Shares  shall be
         traded,  approve the grant of the Options which are the subject of this
         Agreement as provided in Section 15(a) of this Agreement.

         4.       Exercise After Termination of Service.

         After the Optionee  ceases to be an Employee of the  Corporation or any
         Subsidiary of the Corporation,  as the case may be, whether as a result
         of  voluntary  termination,  termination  by the  Corporation  or  such
         Subsidiary or by the normal retirement,  early retirement or disability
         (excluding  Permanent  Disability as defined in Section 5 below) of the
         Optionee,  only such Options that have vested and become exercisable on
         or  before  the  Date of  Termination  (as  defined  in the  Employment
         Agreement) may be exercised by the Optionee,  his attorney-in-fact,  or
         his guardian,  as appropriate,  at any time after the date on which the
         Optionee  ceases to be an  Employee  but no later  than the  earlier of
         ninety  (90) days  after the  Optionee  ceases  to be  employed  by the
         Corporation or such Subsidiary or the last day of the fixed term of the
         Option;  provided,  however,  that, in the event that the employment of
         Optionee  is  terminated  for  Cause  (as  defined  in  the  Employment
         Agreement),  any then outstanding Options held by Optionee,  whether or
         not  vested  and  exercisable  by  Optionee  as of  the  date  of  such
         termination  of employment for Cause,  shall  thereupon be canceled and
         terminated  in their  entirety and be of no further force or effect and
         Optionee  shall have no further  rights  thereto or thereunder or under
         this Agreement.

         5.       Exercise In Case of Death or Permanent Disability.

         If the Optionee shall die or become  permanently  and totally  disabled
         within the meaning of relevant  provisions of the Employment  Agreement
         (hereinafter  referred to as  "Permanently  Disabled"  or a  "Permanent
         Disability")  while an employee of the  Corporation  or of a Subsidiary
         thereof, and Optionee, at the time of the Optionee's death or Permanent
         Disability,  shall have been entitled to exercise all or any portion of
         the Options granted hereby, then the Options may be so exercised by the
         Optionee  or his  legal  representative,  as the case may be, or by his
         estate,  or by a person who  acquires the right to exercise the Options
         by  bequest  or  inheritance,  at any time  after  the date of death or
         Permanent  Disability  but no later than the earlier of (a) twelve (12)
         months after the date of death, Permanent Disability of the Optionee or
         (b) the last day of the fixed term of the Options.

         any of the events set forth in Section 7 hereof), shall equal:

         this Agreement,  the Fair Market Value of the Shares as of July 3, 2003

         of this Agreement, Five Dollars ($5.00) per Share.

         per Share.

         7.       Adjustments Upon Change of Shares.

                  (a) In the event of a reorganization,  merger,  consolidation,
         reclassification,  recapitalization,  any  combination  or  exchange of
         Shares,  stock split,  stock  dividend,  rights offering or other event
         affecting the  capitalization of the Corporation,  the number and class
         of Shares  then  subject  to the  Options as of the  effective  date or
         record date of any such  event,  and the price per Share  payable  upon
         exercise of the Options,  shall be  equitably  adjusted by the Board to
         reflect any such event.

                  (b) Upon the effective  date of any merger,  consolidation  or
         reorganization  of the  Corporation  with one or more  corporations  or
         other legal  entities  in which the  Corporation  is not the  surviving
         corporation or entity, or upon the effective date of any liquidation of
         the Corporation or of a transfer of substantially  all of the assets or
         transfer  of more  than  fifty  percent  (50%) of the then  outstanding
         Shares of the  Corporation  to a theretofore  unaffiliated  third party
         (hereinafter  collectively  referred  to  as  the  "Transaction"),  any
         Options  granted  hereby  which have not vested and become  exercisable
         (prior to or by  reason  of the  Transaction)  shall  terminate  unless
         provisions  have  been  made in  writing  in  connection  with any such
         Transaction  for  the  assumption  of  such  unvested  Options  by such
         successor  employer   corporation  or  other  entity  or  a  parent  or
         subsidiary  thereof or for the substitution of such unvested Options by
         new options covering shares or other equity interests of such successor
         corporation  or other entity,  with  appropriate  adjustments as to the
         number,  kind and prices of shares or other equity interests,  in which
         event the unvested Options or the new options substituted  therefor, as
         the case may be,  shall  continue to be  exercisable  in the manner and
         upon  the  terms  set  forth  in  this  Agreement.  Prior  to any  such
         termination of any then unvested Options upon the effective date of any
         such Transaction,  the Board may, in its sole discretion,  grant to the
         Optionee  the right  immediately  prior to the  effective  date of such
         Transaction to exercise the Options, in whole or in part, provided that
         all conditions  precedent to the vesting thereof (prior to or by reason
         of the Transaction)  set forth herein,  other than the passage of time,
         shall have been satisfied. In any such event, the Corporation will mail
         or cause to be  mailed  to the  Optionee  a notice  (the  "Acceleration
         Notice")  specifying  the date  which  is to be  fixed as of which  all
         holders of record of the Shares  shall be entitled  to  exchange  their
         Shares for securities,  cash or other property  issuable or deliverable
         pursuant to such Transaction.  The Acceleration  Notice shall be mailed
         at least fifteen (15) days prior to such  specified  date. In the event
         that  any  then  outstanding  Options  which  have  vested  and  become
         exercisable  (prior  to  or by  reason  of  the  Transaction)  are  not
         exercised in their entirety on or before the date specified therefor in
         the  Acceleration  Notice,  all such Options and all rights  thereunder
         shall  terminate  and be canceled as of said date and any Options which
         have not so vested  and become  exercisable  as of said date shall also
         terminate and be canceled in their entirety.

                  (c) Upon any  adjustment  made pursuant to this Section 7, the
         Corporation  will,  upon  request,  deliver  to  the  Optionee  or  his
         successor a certificate or the Corporation's  Secretary or an Assistant

                                      -4-

<PAGE>

         Secretary  setting forth the adjusted Option price thereafter in effect
         and the number and kind of shares,  other  securities or other property
         thereafter purchasable upon the exercise of the Options.

                  (d)  The  determination  of  the  Board  with  respect  to any
         adjustments effected pursuant to this Section 7 shall be conclusive and
         binding on the Optionee.

         8.       Non-Transferability of Options

         This Option Agreement shall be binding upon and inure to the benefit of
         the  parties   hereto  and  any   successor  to  the  business  of  the
         Corporation,  but none of the  Options  nor any  rights  granted to the
         Optionee hereunder shall be transferable or assignable,  in whole or in
         part, by the Optionee  otherwise than by will or by the laws of descent
         and distribution, and, during the lifetime of the Optionee, the Options
         and rights  granted to the Optionee  hereunder may be exercised only by
         his except as otherwise expressly provided for herein.

         9.       Registration or Qualification of Shares.

         The Options  shall be subject to the  requirement  that, if at any time
         the Board shall determine,  in its sole  discretion,  that the listing,
         registration or qualification of the Shares subject to the Options upon
         any securities exchange,  inter-dealer quotation market system or under
         any state or federal law,  including  the  Securities  Act of 1933,  as
         amended  (the  "Securities  Act"),  or the  consent or  approval of any
         governmental  regulatory body, is necessary or desirable as a condition
         of, or in connection  with, the granting of the Options or the issue or
         purchase of Shares hereunder, then the Options may not be exercised, in
         whole or in part,  unless such  listing,  registration,  qualification,
         consent or approval  shall have been  effected or obtained  free of any
         conditions not  acceptable to the Board.  The  Corporation  may, in its
         sole  discretion,  at any time and from time to time, file (or maintain
         the  effectiveness  of) a registration  statement  under the Securities
         Act,  and list,  register  or qualify  under any other state or federal
         law, all or any portion of the Options and the Shares issuable upon the
         exercise  thereof,  but nothing set forth  herein  shall  obligate  the
         Corporation  to  file  or  effect  any  such  registration   under  the
         Securities  Act  or  listing  or  qualification   upon  any  securities
         exchange,  inter-dealer  quotation  market  system  or under  any other
         federal or state securities law.

         10.      Compliance with Securities and Other Applicable Law.

         The grant of Options and the  issuance  of Shares upon the  exercise of
         Options shall be subject to compliance with all applicable requirements
         of  federal,  state and foreign  law with  respect to such  securities.
         Options may not be exercised  if the  issuance of Shares upon  exercise
         would  constitute  a  violation  of any  applicable  federal,  state or
         foreign securities laws or other law or regulations or the requirements
         of any stock  exchange or  inter-dealer  quotation  market  system upon
         which the Shares may then be listed.  In  addition,  no Options  may be
         exercised unless (a) a registration  statement under the Securities Act
         shall at the time or exercise of the Options be in effect with  respect
         to the  Shares  issuable  upon  exercise  of the  Options or (b) in the
         opinion of legal counsel to the  Corporation,  the Shares issuable upon
         exercise of the Options may be issued in  accordance  with the terms of
         an  applicable  exemption  from the  registration  requirements  of the
         Securities  Act. The  inability of the  Corporation  to obtain from any
         regulatory body having  jurisdiction  the authority,  if any, deemed by
         the Corporation's  legal counsel to be necessary to the lawful issuance
         and sale of any Shares  hereunder  shall relieve the Corporation of any
         liability  in respect of the failure to issue or sell such shares as to
         which  such  requisite  authority  shall not have been  obtained.  As a
         condition to the exercise of any of the Options,  the  Corporation  may
         require  the  Optionee  to  satisfy  any  qualifications  that  may  be
         necessary or  appropriate,  to evidence  compliance with any applicable
         law or  regulation  and to make any  representation  or  warranty  with
         respect hereto as may be requested by the Corporation.

         11.      Representations at Time of Exercise: Legend.

         The Board may  require,  as a condition  to the exercise of the Options
         granted  pursuant  to this  Agreement,  in whole  or in part,  that the
         Corporation   receive   from   Optionee   or   his   successor,    such
         representations,

                                      -5-

<PAGE>

         warranties and  agreements,  at the time of any such  exercise,  to the
         effect that all Shares  acquired upon  exercise of the Options,  or any
         part thereof,  shall be sold, transferred or otherwise disposed of only
         upon  compliance with the  registration  requirements of the Securities
         Act or in reliance on an exemption therefrom which is the subject of an
         opinion from the Corporation's legal counsel. The certificate issued to
         evidence such Shares shall bear  appropriate  legends  summarizing such
         restrictions on the disposition thereof.

         12.      Reservation of Shares.

         The  Corporation  shall be under no  obligation  to  reserve  Shares to
         satisfy the Options granted  pursuant to this  Agreement.  The grant of
         Options to the Optionee  hereunder shall not be construed to constitute
         the  establishment  of a trust of such Shares and no particular  Shares
         shall  be   identified  as  optioned  and  reserved  for  the  Optionee
         hereunder.  The  Corporation  shall be deemed to have complied with the
         terms of this Agreement if, at the time of issuance and delivery of the
         Shares  pursuant  to the  exercise  of an option,  it has a  sufficient
         number of Shares  authorized and unissued (or held in its treasury) for
         purposes of this  Agreement,  irrespective of the date when such Shares
         were authorized.

         13.      Definitions.

         Except as otherwise  defined in this  Agreement,  the  following  terms
         shall have the following meanings:

                  (c)  "Employee"  means  any  person  treated  as  an  Employee
         (including an officer or director of the Corporation) who is treated as
         an Employee on the  records of the  Corporation  and is deemed to be an
         Employee at Common Law and as interpreted by the U.S.  Internal Revenue
         Service under the Code.

                  (d) "Fair Market  Value" means as of any date the value of the
         Shares of the Corporation as determined by the Board in its discretion,
         or by the Corporation in its discretion, subject to the following:

                           If, on such date, the Shares are listed on a national
                   or regional  securities  exchange or quoted in a inter-dealer
                   quotation market system,  the Fair Market Value of each Share
                   shall be the  closing  price of a Share (or the mean  between

                   quoted instead) as quoted on the NASDAQ National Market,  the
                   NASDAQ  Small Cap Market or such other  national  or regional
                   securities  exchange or inter-dealer  quotation market system
                   constituting the primary market for the Shares as reported in
                   the  Wall  Street  Journal  or  such  other  sources  as  the
                   Corporation  deems  reliable.  If the relevant  date does not
                   fall on a date on which the Shares  have been  traded on such
                   securities exchange or been quoted in such market system, the
                   date on which Fair Market Value shall be established shall be
                   the last date on which the Shares were so traded prior to the
                   relevant  date,  or such other  appropriate  date as shall be
                   determined  by the Board in its sole  discretion;  and, if on
                   such date, there is no public market for the Shares, the Fair
                   Market Value of a Share shall be as  determined  by the Board
                   in good faith without regard to any restriction  other than a
                   restriction which, by its terms, will never lapse.

                  (e)  "Non-Statutory  Stock  Option"  means a stock  option not
         intended to be, or which does not qualify, as an Incentive Stock Option
         within the meaning of Section 422 et seq. of the Code.

                  (f)  "Subsidiary" or  "Subsidiaries"  means any corporation or

15.      Miscellaneous.

                  (a)  Termination.  Anything  contained  herein to the contrary
         notwithstanding,  in the event that the shareholders of the Corporation
         do not  ratify and  approve  the grant of the  Options to the  Optionee
         pursuant  to  this  Agreement  within  twelve  (12)  months  after  the
         Effective Date at the next Annual or Special Meeting of Shareholders of
         the  Corporation,  unless  shareholders  approval  of the  grant of the
         Options to Optionee  under this  Agreement is no longer  required under
         the New York Business  Corporation Law or any other applicable New York
         or California  statute,  law or regulation and/or by the record date of
         any such Shareholders Meeting,  subject,  however, to the provisions of
         Section 162(m) of the Code, then this Agreement and the Options granted
         hereby shall automatically terminate, be canceled in their entirety and
         the Optionee shall forfeit all rights with respect thereto or otherwise
         under this Agreement and be of no further force of effect.

                  (b) Acknowledgment.  The Options may not be exercised,  to the
         extent  vested and  exercisable,  until the Optionee  dates,  signs and
         returns a copy of this Agreement to the Corporation.

                  (c) No Right as  Shareholder.  Neither  the  Optionee  nor his
         successor  shall have any rights as a  shareholder  of the  Corporation
         with  respect to any Shares  subject to the Options  before the date of
         issuance to the  Optionee of a  certificate  or  certificates  for such
         Shares in the name of the Optionee or such successor.

                  (d) No Right to Continued  Employment.  The Options  shall not
         confer upon the Optionee  any express or implied  right with respect to
         continuance of employment by the Corporation or any Subsidiary thereof,
         for any  specific  or  minimum  period  of time  under  the  Employment
         Agreement  or  otherwise,  nor  shall the  grant or  existence  of such
         Options  interfere in any way with the right of the Corporation or such
         Subsidiary to terminate such employment at any time.

                  (e)  Counterparts.  This  Agreement  may be executed in two or
         more counterparts,  each of which shall be deemed to be an original and
         all of which together shall  constitute but one and the same instrument
         provided that each of the parties hereto executes such counterpart.

                  (f) Choice of Law. This  Agreement and the  respective  rights
         and obligations of the Optionee and the Corporation  hereunder shall be
         governed  by the  laws  of  the  State  of New  York  with  respect  to
         agreements to be performed  wholly in the State of New York and without
         giving  effect to the  conflicts of law,  statutes and doctrines of New
         York  (except for Section  5-1401 of the New York  General  Obligations
         Law) or of any other jurisdiction.
