Exhibit 4.5

                            ORBIT SEMICONDUCTOR, INC.

                            1994 STOCK INCENTIVE PLAN

Section 1.  Purpose.

     The  purpose of this stock  incentive  plan (the  "Plan") is to promote the
interests of Orbit Semiconductor,  Inc., a Delaware corporation (the "Company"),
its  affiliates,   and  its  stockholders  by  providing  officers,   directors,
consultants,  and other key employees on whom rests the major responsibility for
the present and future success of the Company,  with an opportunity to acquire a
proprietary interest in the Company, and thereby develop a stronger incentive to
put forth maximum effort for the continued success and growth of the Company and
its affiliates. The opportunity to acquire a proprietary interest in the Company
will aid in attracting and retaining key personnel of outstanding ability.

     This Plan is an amendment and complete  restatement  of, and replaces,  the
former Share Option/Stock Issuance Plan of the Company in its entirety.

Section 2.  Administration.

     All administrative  duties hereunder shall rest with the Board of Directors
of the Company (the "Board"), except to the extent the Board appoints from among
its  members a  committee  to  administer  the Plan (in either  case,  the group
administering  the  Plan  is  hereinafter   referred  to  as  the  "Compensation
Committee" or  "Committee").  The Committee  shall have the duty and  authority,
subject to the provisions of the Plan, to:

     (a) determine which individuals shall receive awards under the Plan and the
nature of each award;

     (b) grant the awards under the Plan;  and issue shares in  connection  with
such awards, as provided in the Plan.

     (c)  determine the terms and  conditions  of the awards,  which need not be
identical, including exercise dates, limitations on exercise,  restrictions, and
the price and payment terms;

     (d)  determine  the  limitation,  if any, on the number of shares  acquired
under an award which may be sold by an awardee in any year;

     (e) prescribe the form or forms of the  instruments  evidencing  any awards
made under the Plan and of any of the  instruments  required under the Plan, and
to change such forms from time to time;

     (f) adopt,  amend and rescind  such rules and  regulations  and to make all
other  determinations  in connection with the  administration  of the Plan as it
deems necessary or appropriate; and

     (g)  correct  any  defect  or  supply  any   omission  or   reconcile   any
inconsistency  in the Plan or in any Award  agreement  in the  manner and to the
extent it shall deem expedient to carry the plan into effect.

In making the foregoing determinations,  the Committee may take into account the
nature of the services  rendered by the respective  awardees,  their present and
potential  contributions to the Company's success, and such other factors as the
Committee, in its discretion, shall deem relevant.

     The  construction  and  interpretation  by the  Committee  of the terms and
provisions of the Plan and the agreements entered into thereunder shall be final
and conclusive.  No Committee  member or director shall be liable for any action
or determination taken or made under or with respect to the Plan or any Award in
good faith.

<PAGE>

Section 3.  Awards.

     Awards made under the Plan  ("Awards")  may be in the form of share options
("Options"),  stock  appreciation  rights  ("SARs"),  grants of  Company  shares
subject  to  certain  restrictions  ("Restricted  Stock"),  or  any  combination
thereof, as described hereinafter.

Section 4.  Eligibility.

     (a)  Individuals  eligible  to  participate  in the  Plan  shall  be  those
officers, directors, executives,  supervisory personnel and consultants, as well
as other  employees  of the Company or an  Affiliate  (as defined in Section 18)
determined  in the sole  discretion of the  Committee,  who are in a position to
make a significant  contribution to the  profitability and growth of the Company
and its Affiliates.  In no event, however, may any person who is not an employee
of the Company or any of its  related  corporations  participate  in the Plan if
such  participation is (a) prohibited,  or (b) restricted  (either absolutely or
subject to various  securities  requirements,  whether legal or  administrative,
being complied with), in the jurisdiction in which such person is resident under
the relevant  securities laws of that jurisdiction.  Provided Always That in the
case of (b)  above,  the  relevant  person's  participation  in the  Plan may be
effected at the absolute  discretion  of the  Committee if  compliance  with the
relevant  securities  requirements  of the  jurisdiction in which such person is
resident is not impractical  (having regard to the nature of those requirements)
and would not involve  undue  expense.  An  individual  who is the grantee of an
Award shall be hereinafter known as a "Participant."

     (b) To the extent required by Rule 16b-3 of the Exchange Act (as defined in
Section 18) or Section  162(m) of the Internal  Revenue Code of 1986, as amended
(the  "Code"),  any person who is a  director  or officer of the  Company or any
Affiliate  shall be granted  Awards  only if such person has been  selected  for
participation  and the terms and provisions of such Awards have been  determined
solely by, and in the sole  discretion of, a Committee of two or more directors,
each of whom is a Disinterested  Person (defined below) and an Outside  Director
(defined  below).  The  foregoing  provision  does not apply to any grant  which
occurs prior to the date the Company  first  registers  its Ordinary  Shares (as
defined in Section 5) under Section 12 of the Securities Exchange Act of 1934.

     (c) Unless  otherwise  permitted under Rule 16b-3, any right of the Company
under the Plan regarding the determination or approval of the form of payment by
the  Company to the  participant  who is a director  or officer of the  Company,
shall be made solely by a Committee of two or more  directors  each of whom is a
"Disinterested Person."

     (d) For the purposes of the Plan,

          (i) a person  is a  "Disinterested  Person"  only  either  (x) if such
     director has not, during the one year prior to service as an  administrator
     of this Plan or during  such  service,  been  granted or awarded any Awards
     under this Plan or any equity  securities  (as defined in Rule 16a-4 of the
     Exchange  Act) of any other plan of the Company or an  Affiliate  or (y) if
     such person is not disqualified  from being a "disinterested  person" under
     paragraph (c)(2) of Rule 16b-2 of the Exchange Act; and

          (ii) the term  "officer"  shall have the same  meaning as in paragraph
     (f) of Rule 16a-1 of the Exchange Act.

          (iii) the term  "Outside  Director"  shall have the same meaning as in
     Section 162(m) of the Code and the regulations promulgated thereunder.

Section 5.  Shares Subject to the Plan.

     The shares that may be issued  pursuant  to Awards  under the Plan shall be
ordinary shares, S$0.01 par value, of the Company ("Ordinary Shares"). The total
shares subject to Awards issued pursuant to the grant of options pursuant to the
Plan shall not exceed 2,250,000 Ordinary Shares, and the total shares subject to
all Awards  issued  pursuant  to the Plan shall not  exceed,  in the  aggregate,
2,250,000 Ordinary Shares (one or more shares per Award).

<PAGE>

To the extent  required to satisfy the performance  goal  requirement of Section
162(m) of the Code, no employee may be granted more than 100,000  Options during
the term of the Plan. If any Award lapses or terminates  for any reason  without
having  been  exercised  in full prior to the lapse or  termination,  the shares
covered by such  Award or  portion  thereof  remaining  unexercised,  may become
subject to  subsequent  Awards made or to be made under the Plan.  Shares issued
under the Plan shall be authorized  but  previously  unissued  shares.  Ordinary
Shares issuable upon exercise of Awards granted under the Plan may be subject to
such  restrictions on transfer,  forfeitability,  repurchase  rights,  rights of
first refusal, or other restrictions as shall be determined by the Committee.

Section 6.  Options.

     (a) Granting of Options.  Subject to the terms and  conditions of the Plan,
the  Committee  may grant Options to purchase  Ordinary  Shares  subject to such
terms  and  conditions  as the  Committee  may  determine.  The day on which the
Committee  approves the granting of an Option shall be considered as the date on
which such Option is granted unless the Committee  approves a future date as the
date of grant.  Options shall be designated  as either  incentive  stock options
("ISOs") or nonstatutory stock options ("NSOs") at the time of grant. ISOs shall
comply  with the  requirements  of Section 422 of the Code.  No person  shall be
granted any ISO under the Plan  unless at the time such Option is granted,  such
person is an employee of the Company or of any Parent  Corporation or Subsidiary
(as such terms are  defined  in Section  18),  and  unless the  requirements  of
paragraph  (c) are  satisfied,  does not own,  directly  or  indirectly,  shares
possessing  more than 10% of the total  combined  voting power of all classes of
shares of the Company or of any Parent Corporation or Subsidiary.

     (b) Option  Price.  The  purchase  price per Ordinary  Share  subject to an
Option (the  "Option  Price")  shall be fixed by the  Committee  at the time the
Option is granted  Provided  Always That in no event may the  purchase  price be
less than the par value of an Ordinary Share. In the case of ISOs, such purchase
price  shall not be less than the fair market  value  ("Fair  Market  Value") of
Ordinary  Shares at the time the Option is granted.  Fair Market Value,  for all
applicable  purposes  under the Plan,  shall be  determined by the Board in good
faith taking into account any applicable requirements of law.

     (c)  Incentive  Stock  Options.  Options  granted  under the Plan which are
intended  to be ISOs  shall be  specifically  designated  as ISOs  and  shall be
subject to the following additional terms and conditions:

          (i) 10%  Stockholder.  If any employee to whom an ISO is to be granted
     under  the  Plan is at the  time of the  grant of such  option  the  owner,
     directly or  indirectly,  of shares  possessing  more than 10% of the total
     combined  voting  power of all  classes of shares of the  Company or of any
     Parent  Corporation  or any  Subsidiary  ("10%  Stock  Holder"),  then  the
     following special provisions shall be applicable to the ISO granted to such
     individual:

               (x) The Option Price per share shall not be less than 110% of the
          Fair Market Value of one Ordinary Share at the time of grant; and

               (y) The option  exercise  period  shall not exceed five (5) years
          from the date of grant.

     (d) Method of  Exercising  Options.  A  Participant  may exercise an Option
granted  hereunder  by  delivering  to the  Company  at its main  office (to the
attention  of the  Secretary)  written  notice of  exercise,  which notice shall
specify  the  number  of  shares  with  respect  to which  the  Option  is being
exercised, together with payment in cash of the Option Price in exchange for the
Company's issuance and delivery of certificates therefor. The Committee,  in its
discretion,  may permit cash payments of the Option Price to be in  installments
or  pursuant  to a  recourse  note  upon  such  terms  as  the  Committee  deems
appropriate.  At the request of a  Participant,  and to the extent  permitted by
applicable  law, the Committee may approve  arrangements  with a brokerage  firm
under which such firm, on behalf of the  Participant,  will pay the Option Price
to the  Company  and the Company  will  promptly  deliver to such firm the share
certificates in respect to the shares exercised,  so that the firm may sell such
shares, or a portion thereof,  for the account of the Participant subject to the
terms of the Option.

<PAGE>

     (e) Amount  Exercisable.  (i) Each  Option may be  exercised,  from time to
time,  in whole or in part, so long as it is valid and  outstanding,  subject to
any limitations with respect to the number of shares for which the Option may be
exercised at a particular time and to such other  conditions as the Committee in
its discretion may specify upon granting the Option.

          (ii) Ordinary Shares of the Company that are acquired  pursuant to the
     exercise  of an ISO which has been  granted to an  employee  under the Plan
     shall be deemed to be  acquired  pursuant to the  exercise of an  incentive
     stock option under Code Section 422,  only to the extent that the aggregate
     fair market value  (determined as of the respective date or dates of grant)
     of the  Ordinary  Shares  with  respect  to which  such ISO,  and all other
     incentive  stock options which are granted to such employee  under the Plan
     (and under any other  incentive  stock  option plans of the Company and any
     Parent  Corporation  and any Subsidiary) are exercisable for the first time
     by such employee in any one calendar year, does not exceed $100,000.

          (iii) To effectuate the provisions of paragraph (e)(ii), the Committee
     may designate the Ordinary Shares that are treated as acquired  pursuant to
     the exercise of an incentive stock option under Code Section 422 by issuing
     a separate certificate for such shares and identifying such certificates as
     incentive stock option shares in its statutory register.

Section 7.  Stock Appreciation Rights.

     (a) Each SAR is the right to  receive  payment  of an  amount  equal to the
increase, if any, in the Fair Market Value of one Ordinary Share over the period
of time between the date of grant of the SAR and the date of exercise.

     (b) SARs may be granted in conjunction  with an Option,  either at the time
of grant or thereafter, or separately.  SARs shall be credited to an SAR account
to be  maintained  for the  Participant.  An Award of an SAR shall not entitle a
Participant  to any  dividend,  voting or other rights of a  shareholder  of the
Company.

     (c) SARs issued in  conjunction  with an Option shall be exercisable to the
extent that such Option shall be exercisable and in lieu of the exercise of such
Option which, to the extent of the exercise of the SAR, shall lapse.  SARs which
are granted  independent of an Option shall be  exercisable  during the exercise
period set forth in the SAR agreement.

     (d) Upon the exercise of an SAR, the Participant shall receive,  in respect
thereof,  payment  in cash,  Ordinary  Shares  or a  combination  of both as the
Committee,  in its sole discretion,  shall determine, of the amount by which the
Fair Market Value of an Ordinary Share on the date of exercise  exceeds the Fair
Market value of such share on the date of the SAR's grant.

Section 8.  Restricted Stock Awards.

     (a) Restricted Stock means one or more shares of Ordinary Shares awarded to
a  Participant  pursuant  to this  Section  8,  which  are  subject  to  certain
limitations  during a specified  restriction  period.  Restricted Stock shall be
issued to a Participant without payment of any consideration.  A certificate for
Restricted  Stock so  awarded  shall be issued  in the name of each  Participant
receiving the Award and shall bear a restrictive  legend  prohibiting  the sale,
transfer,  pledge or  hypothecation  of the Restricted  Stock evidenced  thereby
until the expiration of the restriction period set forth therein.

     (b) Holders of  Restricted  Stock shall have the right to vote such shares.
In granting an Award of Restricted Stock, the Committee, in its sole discretion,
may authorize the  Participant to receive cash dividends or other  distributions
with respect to such Ordinary  Shares or may direct that they be retained by the
Company.

<PAGE>

     (c) Upon the expiration of the  restriction  period  contained in an Award,
all  restrictions  upon such Restricted  Stock shall lapse and a new certificate
representing such shares will be issued without the restrictive legend described
in (a) above.

Section 9.  Non-Transferability of Awards.

     Awards of Options and SARs and Awards of Restricted Stock to the extent the
restriction  period has not expired,  shall not be transferable by a Participant
other  than by will or under  the laws of  descent  and  distribution,  and with
respect to Options and SARs shall be exercisable during his lifetime only by him
except as provided in Section 10.

Section 10.  Exercise Period for Options and SARs.

     (a) Generally.  Each Award of an Option or SAR shall expire on such date as
the Committee shall determine on the date such Award is granted, but in no event
after the  expiration  of ten years  from the day on which such Award is granted
(or five  years in the case of ISOs  granted  to  persons  described  in Section
6(c)(i)  and  Participants  who are not  employees  of the Company or any of its
related corporations on the relevant date of grant), and in all cases each Award
shall be subject to earlier termination as provided in the Plan.

     (b) Effect of Termination  of Employment.  No Award of an Option or SAR may
be  exercised  by a  Participant  unless,  at the  time  of such  exercise,  the
Participant  is, and  continuously  since the date of grant of his or her Award,
has been an  employee or a director  of or a  consultant  for one or more of the
Company or an  Affiliate,  except that  subject to Section 11, and if and to the
extent the Award agreement or instrument so provides:

          (i) the Award may be exercised within the period of three months after
     the date  the  Participant  ceases  to be an  employee  or  director  of or
     consultant for any of the foregoing  entities (or within such lesser period
     as may be specified in the Award agreement or instrument);

          (ii) if the  Participant  dies while an employee or a director of or a
     consultant  for the Company or an  Affiliate,  or within three months after
     the  Participant  ceases to be such an employee or director or  consultant,
     the Award may be exercised by the person to whom it is  transferred by will
     or the laws of descent and distribution within the period of one year after
     the date of death (or within such lesser  period as may be specified in the
     Award agreement or instrument); and

          (iii) if the  Participant  becomes  disabled  (within  the  meaning of
     Section  22(e)(3)  of the  Code)  while an  employee  or a  director  of or
     consultant  for the  Company or an  Affiliate,  the Award may be  exercised
     within the period of one year after the date the  Participant  ceases to be
     an employee or director of or consultant for any of the foregoing  entities
     because  of  such  disability  (or  within  such  lesser  period  as may be
     specified in the Award agreement or instrument);

provided,  however,  that in no event may any such Award be exercised  after the
expiration date of the Award. Any Award or portion thereof that is not exercised
during  the  applicable  time  period  specified  above (or any  shorter  period
specified in Award  agreement or instrument)  shall be deemed  terminated at the
end of the applicable time period for purposes of Section 5 hereof.

     (c) Effective Date of Exercise. Subject to the provisions of paragraphs (a)
and (b) of this  paragraph and Section 11, the exercise of an Award of an Option
or SAR by a Participant for cash, in whole or in part,  shall take effect on the
date of receipt by the Company of written notice of exercise by the Participant,
together with any required payment for such exercise; provided, however, if, (i)
such Award is owned by an officer or director of the Company,  (ii) such date of
receipt  does not occur during the period  beginning  on the third  business day
following  the date of release of the  financial  data  specified  in  paragraph
(e)(1)(ii) of Rule 16b-3 and ending on the twelfth  business day following  such
date,  and (iii) the  Company  has not  received  a  no-action  letter  from the
Securities and Exchange  Commission that such Award or class of Awards is exempt
from the exercise  period  requirements of paragraph  (e)(3) of Rule 16b-3,  the
Company shall,  within 10 days of receipt of the notice of exercise,  notify the
Participant  in writing

<PAGE>

of the lack of a  no-action  letter,  and the  exercise  of the Award shall take
effect as of the first day of the  period  described  above in clause  (ii) next
following the date of such receipt, unless the Participant responds, in writing,
in substance and form  satisfactory to the Company,  within 5 days of receipt of
the Company's notification, that the date of receipt is to remain effective.

Section 11.  Vesting of Awards.

     (a) An Option or SAR may be  exercised,  and payment shall be made upon the
exercise of such Award,  only to the extent that such Award has vested. An Award
of Restricted Stock may also be subject to a vesting schedule.

     Awards shall vest in accordance with the schedule or terms set forth in the
Award agreement executed by the Participant and a duly authorized officer of the
Company.  An Award agreement may,  subject to compliance  with applicable  laws,
provide that an Award may be forfeited  for cause (as defined in the  agreement)
or that an  Award's  vested  status may be  accelerated  at any time in the sole
discretion of the Board of Directors.  Notwithstanding the foregoing, unless the
Board of Directors  specifically  authorizes a different  vesting  schedule with
respect to an Award, an Award shall vest based on the collective  number of full
years of service  that such  Participant  has  completed  with the  Company  and
Affiliates  since the Award's date of grant,  in  accordance  with the following
schedule:

     Number of Years of Service               Percentage of Award Available
         Since Date of Grant                    for Exercise (Cumulative)
     --------------------------               -----------------------------
                  1                                          25%
                  2                                          50%
                  3                                          75%
              4 or more                                     100%

     (b)  Notwithstanding  anything to the contrary in this Section 11, upon the
exercise  of an Option or SAR by a  director  or  officer  of the  Company,  the
Company shall  determine if such  exercise  complies  with  paragraph  (c)(1) or
(e)(4) of Rule 16b-3.  If such exercise does not so comply,  the Company  shall,
within 5 days of receipt of the notice of exercise,  notify the Participant,  in
writing,  of such  non-compliance  and such  exercise  shall not be given effect
unless the Participant  responds in writing,  in substance and form satisfactory
to the Company,  within 5 days of receipt of the  Company's  notification,  that
such exercise is to remain effective.

Section 12.  Capital Adjustments Affecting Ordinary Shares.

     In the  event  that the  outstanding  Ordinary  Shares of the  Company  are
changed  into or  exchanged  for a  different  number or kind of shares or other
securities of the Company by reason of any  recapitalization,  reclassification,
stock split, stock dividend, combination or subdivision,  merger, consolidation,
or other similar transaction, appropriate adjustment shall be made in the number
and kind of shares  available  under the Plan and under any Awards granted under
the Plan. Such adjustment to outstanding  Awards shall be made without change in
the total value  applicable to the unexercised  portion of such Awards as of the
date of the adjustment.  No such adjustment shall be made with respect to an ISO
which  would,  within the  meaning  of any  applicable  provisions  of the Code,
constitute a modification, extension or renewal of any such option or a grant of
additional benefits to the holder of such Option.

Section 13.  Change In Control.

     Notwithstanding  anything contained herein to the contrary, in the event of
a Chance In Control,  as hereinafter  defined,  (i) all Awards then  outstanding
shall become immediately  exercisable and (ii) any restrictions then outstanding
on any Award of Restricted Stock which have not lapsed shall immediately  lapse.
For  purposes of this  section,  a "Change In Control" is deemed to occur at the
time when either (i) any entity,  person or group  (other than the Company or an
Affiliate  or any  savings,  pension or other  benefit  plan for the  benefit of
employees of the Company) which theretofore  beneficially  owned less than forty
percent (40%) of the Ordinary Shares then

<PAGE>

outstanding acquires Ordinary Shares in a transaction or series of transactions,
not  previously  approved by the Board,  that results in such entity,  person or
group  erectly  or  indirectly  owning  forty  percent  (40s)  or  more  of  the
outstanding  Ordinary  Shares,  or (ii) the  election or  appointment,  within a
twelve (12) month  period,  of persons to the Board who are not Board members at
the beginning of such twelve (12) month period,  whose  election or  appointment
was not  approved by a majority of those  persons who were Board  members at the
beginning of such period,  and which newly  elected or appointed  Board  members
shall constitute a majority of the Board.

Section 14.  General Restrictions.

     (a) Investment Representations; Legends. The Company may require any person
to whom an Award is granted, as a condition of exercising such Award, to

          (i) give written assurances, in substance and form satisfactory to the
     Company,  that such person is acquiring the Ordinary  Shares subject to the
     Award for his own account for investment and not with any present intention
     of selling or otherwise distributing the same, and to such other effects as
     the Company deems  necessary or appropriate in order to comply with federal
     and applicable state securities laws;

          (ii)  if the  Participant  is a  director  or  officer,  give  written
     assurances,  in substance and form  satisfactory to the Company,  that such
     person  has  consulted  with  competent  counsel as to the  application  of
     Section 16(b) of the Securities Exchange Act of 1934 to such exercise.

     Certificates  representing  shares  issued upon exercise of the Award shall
bear a legend  prohibiting  transfer  of such shares  unless,  in the opinion of
competent   counsel,   such  transfer  is  not  inconsistent  with  any  of  the
requirements of any applicable securities law or such legend is not required.

     (b) Compliance With Securities Laws.

          (i) Each Award  shall be subject to the  requirement  that,  if at any
     time counsel to the Company shall determine that the listing,  registration
     or qualification of such Award or the shares subject to such Award upon any
     securities  exchange  or under any state or federal  law, or the consent or
     approval  of  any  governmental  or  regulatory  body,  is  necessary  as a
     condition of, or in connection with the grant of such Award or the issuance
     or purchase of shares  thereunder,  such Award shall not be  effective  and
     shall not be accepted or exercised in whole or in part unless such listing,
     registration,  qualification,  consent or approval shall have been effected
     or obtained on conditions  acceptable  to the Board of  Directors.  Nothing
     herein  shall be deemed to  require  the  Company to apply for or to obtain
     such listing, registration or qualification.

          (ii) The Company shall provide each Participant with such information,
     statements,  discussions  and analyses  with respect to the Company in such
     manner  and at  such  times  as may be  required  under  state  or  federal
     securities laws.

Section 15.  Tax Withholding.

     Tax withholding  obligations,  if any, in connection with an Award shall be
satisfied by a cash payment by the person  receiving the Ordinary Shares subject
to the Award to the Company.

Section 16.  No Rights as Shareholder.

     No recipient of an Award shall have rights as a shareholder with respect to
Ordinary  Shares  covered by his Award until the date of allotment  and issue of
such Ordinary Shares subject to any applicable restrictions thereon; and, except
as  otherwise  provided  in  Section  12  herein  or in an Award  agreement,  no
adjustment  for  dividends,  or  otherwise,  shall  be made if the  record  date
therefor is prior to the date of issuance of such shares.

amend  the  Plan  in any  respect,  except  that  without  the  approval  of the
shareholders of the Company,  the Board of Directors may not make any amendments
that require  approval of the  shareholders  under Rule 16b-3.  As of July 1994,
Rule 16b-3 required  shareholder approval of amendments that materially increase
the  benefits  accruing  to  individuals  who  participate  in  the  Plan,  (ii)
materially  increase the maximum  number of shares which may be issued under the

would require

<PAGE>

shareholder  approval  under Section 422 of the Internal  Revenue Code,  without
obtaining  such  approval,  if such  amendment  would  affect  the status of any
outstanding  ISO as an incentive  stock option under Section 422 of the Code. As
of  July  1994,  Section  422 of  the  Code  required  shareholder  approval  of
amendments  that (A) increase the aggregate  number of shares that may be issued
pursuant to ISOs (except for permissible  adjustments  provided in the Plan), or

not,  without the consent of a  Participant,  affect his or her rights  under an
Award  previously  granted to him or her.  With the  consent of the  Participant
affected,  the Committee may amend  outstanding Award agreements in a manner not
inconsistent with the Plan.

     (b) Notwithstanding the foregoing provisions of paragraph (a)(i) and (iii),
the Board of Directors shall have the right, but not the obligation, without the
consent  of the  Company's  shareholders,  to (i) amend or modify  the terms and
provisions of the Plan and of any outstanding ISOs granted under the Plan or any
shares to be issued  thereunder  to the extent  necessary  to qualify any or all
such  options  or  shares  for  such  favorable  federal  income  tax  treatment
(including  deferral of taxation upon  exercise),  as may be afforded  incentive
stock options under Section 422 of the Code;  and (ii) amend or modify the terms
and provisions of the Plan and of any  outstanding  Award granted under the Plan
or any shares to be issued thereunder to the extent necessary to comply with any
securities law to which,  in the opinion of counsel to the Company,  the Plan or
Award or shares is subject.

Section 21.  Governing Law.

     The Plan and all Award agreements issued hereunder shall be governed by the
laws of the State of Delaware.

Section 22.  Expenses of Administration.

     All costs and expenses incurred in the operation and administration of this
Plan shall be borne by the Company.

Section 23.  Effective Date and Duration of the Plan.

     (a) Effective  Date.  The Plan shall become  effective  when adopted by the
Board of  Directors.  Awards may be granted under the Plan at any time after the
effective date and before the date fixed for termination of the Plan.

     (b) Termination. The Plan shall terminate upon the earlier of (i) the close
of business on the day next  preceding the tenth  anniversary of the date of its
adoption  by the  Board of  Directors,  or (ii) the  date on  which  all  shares
available  for  issuance  under the Plan shall have been issued  pursuant to the
exercise  or  cancellation  of Awards  granted  under  the Plan.  If the date of
termination is determined under (i) above, then Awards  outstanding on such date
shall continue to have force and effect in accordance with the provisions of the
Plan as then in effect and with the instruments evidencing such Awards.Exhibit 4.6

                         KMOS SEMI-CUSTOM DESIGNS, INC.

                             1989 STOCK OPTION PLAN

1.   Purpose of the Plan.

     The purpose of the 1989 Stock  Option Plan (the "Plan) of KMOS  Semi-Custom
Designs, Inc. (the "Company") is to:

     (a) Furnish  incentive to certain key employees  chosen to receive  options
because they are  considered  capable of responding by improving  operations and
increasing profits;

     (b) Encourage selected employees to accept or continue  employment with the
Company or its Affiliates; and

     (c) Increases the interest of selected  employees in the Company's  welfare
through  their  participation  in the  growth in value of the  ordinary  shares,
S$0.01 par value, of the Company ("Ordinary Shares").

     To accomplish the foregoing objectives,  this Plan provides a means whereby
employees may receive options to purchase Ordinary Shares. Options granted under
this Plan ("Options") will be either nonqualified  options ("NQOs") or Incentive
Stock Options  ("ISOs") as defined in Section 422A of the Internal  Revenue Code
of 1986, as amended (the "Code").

2.   Eligible Persons.

     Every  person who at the date of grant is an  employee of the Company or of
any  Affiliate  of the Company is  eligible  to receive  NQOs or ISOs under this
Plan;  provided,  however,  that an ISO may to be granted under this Plan to any
person who owns, directly or indirectly, shares of the Company constituting more
than ten percent of the total combined voting power of the Company's Outstanding
Ordinary  Shares,  or the  stock of an  Affiliate  of the  Company,  unless  the
exercise  price of the ISO at the time the  option  is  granted  is at least 110
percent of the fair market  value of the shares  subject to the option,  and the
option is  exercisable  for no more than five years after the date of grant,  as
set forth in Section 6.2.  The term  "Affiliate"  as used in this Plan;  means a
parent or  subsidiary  corporation,  as  defined  in the  applicable  provisions
(currently  Section 425) of the Code. The term "employee" shall have the meaning
ascribed  for  purposes  of  Section  3401(c)  of  the  Code  and  the  Treasury
Regulations promulgated thereunder and shall include an office or a Director who
is also an employee.

3.   Shares Subject To This Plan.

     The total  number of shares that may be issued upon the exercise of Options
is Three Million (3,000,000)  Ordinary Shares. The shares covered by the portion
of any grant that expires  unexercised  under this Plan shall  become  available
again for grants  under this Plan.  All shares  issued  under this Plan shall be
counted against the Three Million  (3,000,000) share  limitation.  The number of
shares  reserved  for  purchase  under  this Plan is subject  to  adjustment  in
accordance  with the  provisions  for  adjustment in this Plan.  Shares shall be
issued from authorized but previously unissued shares.

4.   Administration.

     This Plan shall be  administrative by the Board of Directors of the Company
(the "Board") or by a committee appointed by the Board which shall not have less
than one Board member (in either case, the "Administrator").  No option shall be
granted to a director of the Company  except (i) by the Board when a majority of
the members of the Board,  and a majority of the directors acting in the matter,
are disinterested  persons,  or (ii) by the Administrator when the Administrator
is composed of three or more persons  having full authority to act in the

<PAGE>

matter and each member of the Administrator is a disinterested person. No Option
shall be granted to an officer of the Company  except (i) by the Board,  or (ii)
by the Administrator  when the Administrator is composed solely of three or more
directors,  or is composed of three or more persons having full authority to act
in the matter and each member of the  Administrator  is a disinterested  person.
"Disinterested  person" for this purpose, shall have the same meaning as in Rule
16b-3 or any successor rule ("Rule 16b-3") under the Securities  Exchange Act of
1934,  as  amended  (the  "Exchange  Act").  This   Administrator  may  delegate
nondiscretionary  administrative  duties to such  employees of the Company as it
deems proper.  Subject to the provisions of this Plan, the  Administrator  shall
have the authority to select the persons to receive  Options under this Plan, to
fix the number of shares that each optionee may  purchase,  to set the terms and
conditions of each Option  (including  whether each Option should be a NQO or an
ISO) and to determine  all other  matters  relating to this Plan.  To the extent
permitted  under all applicable  laws, no member of the  Administrator  shall be
liable for any act or  omission on such  member's  own part,  including  but not
limited to the  exercise of any power or  discretion  given to such member under
this Plan,  except for those acts or omissions  resulting from such member's own
gross  negligence  or  willful  misconduct.  All  questions  of  interpretation,
implementation,  and  application  of  this  Plan  shall  be  determined  by the
Administrator. Such determinations shall be final and binding on all persons.

5.   Granting of Rights.

     5.1 Ten-Year Limitation.  No Options shall be granted under this Plan after
ten years from the date of adoption of this Plan by the Board of Directors.

     5.2 Written Agreement;  Effect. Each Option shall be evidenced by a written
agreement, in form satisfactory to the Company,  executed by the Company and the
person to whom such Option is  Granted.  If the  agreement  relates to an ISO or
NQO, the agreement shall specify whether each option it evidence is an NQO or an
ISO. Failure of the grantee to execute an agreement shall not void or invalidate
the grant of an  Option;  the  Option ay not be  exercised,  however,  until the
agreement is executed.

     5.3  Annual  $100,000  Limitation.  In no  event  shall  an ISO be  granted
pursuant  to this Plan which  would  cause the  grantee to be in receipt of ISOs
covering  shares of the Company which are  exercisable for the first time during
any calendar  year having an aggregate  fair market value,  determined  for each
Option as of the date of grant thereof, in excess of $100,000.

     5.4 Advance  Approvals.  The Administrator may approve the grant of Options
under this Plan to persons who are expected to become  employees of the Company,
but are not employees at the date of approval.  In such cases,  the Option shall
be deemed granted (and the exercise price  determined with reference to the fair
market value of the underlying  shares),  without further approval,  on the date
the grantee becomes an employee and satisfies all  requirements of this Plan for
Options granted on that date.

6.   Terms and Conditions of Options.

     Each Option shall be designated as an ISO or an NQO and shall be subject to
the terms and conditions set forth in Section 6.1. NQOs shall also be subject to
the terms and  conditions  set forth in Section  6.2, but not those set forth in
Section 6.3. ISOs shall also be subject to the terms and conditions set forth in
Section 6.3, but not those set forth in Section 6.2.

     6.1 Terms and  Conditions  to Which All  Options Are  Subject.  All Options
shall be subject to the following terms and conditions:

     split, stock dividend, or recapitalization,  or converted into or exchanged
     for  other   securities  as  a  result  of  a  merger,   consolidation   or
     reorganization, appropriate adjustments shall be made in (A) the number and
     class of shares subject to this Plan and each Option outstanding under this
     Plan,  and (B) the exercise  price of each  outstanding  Option;  provided,
     however,  that the Company shall not be required to

<PAGE>

     issue  fractional  shares  as a result  of any such  adjustment.  Each such
     adjustment shall be determined by the Administrator in its sole discretion,
     which determination shall be final and binding on all persons.

          6.1.2 Corporate Transactions. New option rights may be substituted for
     the  Options  granted  under this Plan,  or the  Company's  obligations  to
     Options  outstanding  under  this  Plan  may  be  assumed,  by an  employer
     corporation  other than the Company,  or by a parent or  subsidiary of such
     employer  corporation,  in  connection  with  any  merger,   consolidation,
     acquisition, separation, reorganization,  liquidation or like occurrence in
     which the Company is  involved,  in such  manner that the then  outstanding
     Options which are ISOs will continue to be "incentive stock options" within
     the  meaning  of  Section  422A of the  Code to the full  extent  permitted
     thereby.  Notwithstanding the foregoing or the provisions of Section 6.1.1,
     if such  employer  corporation,  or parent or  subsidiary  of such employer
     corporation,  does not substitute new option rights for, and  substantially
     equivalent to, the Options granted hereunder, or assume the Options granted
     hereunder,  the Options shall terminate (A) upon dissolution or liquidation
     of  the  Company,   or  similar   occurrence,   or  (B)  upon  any  merger,
     consolidation,  acquisition,  separation, or similar occurrence,  where the
     Company  will  not in  economic  substance  be the  surviving  corporation;
     provided,  however,  that each optionee  shall be mailed notice at least 15
     days  prior  to  such  dissolution,   liquidation,  merger,  consolidation,
     acquisition,  separation, or similar occurrence, and shall have at least 10
     days after the  mailing of such  notice to exercise  any  unexpired  option
     rights granted  hereunder.  All Options are considered  100% vested in such
     event.

          6.1.3 Option Term.  Each Option  granted  under this Plan shall expire
     ten years from the date of its grant or such  earlier date as may be set by
     the Administrator on the date of its grant.

          6.1.4 Time of Option Exercise. Subject to Section 6.3.3, Options shall
     be  exercisable  in  accordance  with the terms of each  eligible  person's
     Option, and shall be exercisable in whole or in part.

          6.1.5  Option  Grant  Date.  Except in the case of  advance  approvals
     described  in Section  5.4,  the date of grant of an Option under this Plan
     shall be the date as of which the Administrator approves the grant.

          6.1.6 Nonassignability of Option Rights. No Option shall be assignable
     or otherwise  transferable by the optionee except by will or by the laws of
     descent and distribution.  During the life of the optionee, an Option shall
     be  exercisable  only by the optionee or the  optionee's  guardian or legal
     representative in the event of disability of the optionee.  In the event of
     voluntary termination of employment or disability,  the optionee must offer
     unexpired  options  to the  Company  under the  terms of any  shareholders'
     agreement in force on the date of such event.

          6.1.7 Payment.  Payment in full, in cash, shall be made for all shares
     purchased at the time  written  notice of exercise of an Option is given to
     the Company,  and proceeds of any payment shall constitute general funds of
     the Company.

          6.1.8 Termination of Employment.  Option rights granted to an optionee
     under this Plan,  to the extent such  rights have not then  expired or been
     exercised,  shall terminate three months after the optionee ceases, for any
     reason and with or without  cause,  to be an employee of the Company or any
     Affiliate of the Company (in either case,  "Employment  Termination"),  and
     shall not be exercisable on or after said date. In no event, however, shall
     any such option be exercisable  after the specified  expiration date of the
     option term.

          6.1.9 Other  Provisions.  Each Option may  contain  such other  terms,
     provisions,  and  conditions  not  inconsistent  with  this  Plan as may be
     determined by the Administrator, and each ISO granted under this Plan shall
     include such  provisions  and  conditions  as are  necessary to qualify the
     Option as an "incentive stock option" within the meaning of Section 422A of
     the Code.

     6.2 Terms and  Conditions to Which Only NQOs Are Subject.  Options  granted
under  this Plan  which are  designated  as NQOs or which  become  NQOs shall be
subject to the following terms and conditions:

          6.2.1 Exercise Price. The exercise price of an NQO shall be determined

terms and conditions:

          6.3.1  Exercise  Price.  The exercise  price of an ISO, which shall be
     approved by the Board of Directors,  shall be determined in accordance with
     the  applicable  provisions  of the Code and shall in no event be less than
     the fair market value  (determined  as described in this Section  6.3.1) of
     the shares  covered by the ISO at the time the ISO is granted,  except that
     the  exercise  price of an ISO granted to any person who owns,  directly or
     indirectly  (or is  treated  as  owning by  reason  of  attribution  rules,
     currently  set  forth  in  Code  Section   425),   shares  of  the  Company
     constituting  more than ten percent of the total  combined  voting power of
     the  Company's  outstanding  shares,  or the stock of any  affiliate of the
     Company,  shall in no event be less than 110  percent  of such fair  market
     value.  In the absence of an  established  market for the shares;  the fair
     market  value   thereof   shall  be   determined   in  good  faith  by  the
     Administrator,  with  reference  to the  Company's  net worth,  prospective
     earning  power,  dividend-paying  capacity,  and  other  relevant  factors,
     including  the  goodwill  of  the  Company,  the  economic  outlook  in the
     Company's  industry,  the  Company's  position  in  the  industry  and  its

     by a recognized  securities dealer, its fair market value shall be the mean
     between the closing high bid and low asked quotations for the shares on the
     date the ISO is granted  (or if there are no quoted  prices for the date of
     grant, then for the last preceding  business day on which there were quoted
     prices)  as  quoted  on the  National  Association  of  Securities  Dealers
     Automated  Quotation System ("NASDAQ"),  or any similar system of automated
     dissemination  of quotations  of  securities  prices then in common use, as
     reported in the Wall Street Journal or similar publication.

     If the shares of the Company are listed on any established  stock exchange,
     its fair  market  value  shall be the mean  between  the highest and lowest
     selling  price or the  closing bid if no sale  occurred,  as quoted on such
     exchange (or the largest such exchange) for the date the ISO is granted (or
     if there are no sales for such date of grant,  then for the last  preceding
     business  day on which  there were  sales),  as reported in the Wall Street
     Journal or similar publication.

          6.3.2  Expiration.  Unless an earlier  expiration date is specified by
     the  Administrator  at the time of grant,  each ISO granted under this Plan
     shall  expire  ten years  from the date of its  grant,  except  that an ISO
     granted to any person who owns,  directly or  indirectly  (or is treated as
     owning by reason of applicable  attribution  rules,  currently set forth in
     Code Section 425), shares of the Company constituting more than ten percent
     of the total combined voting power of the Company's  outstanding shares, or
     the stock of any Affiliate of the Company, shall expire five years from the
     date of its grant.

          6.3.3 Disqualifying Dispositions. If shares acquired by exercise of an
     ISO granted  pursuant to this Plan is disposed of within two years from the
     date of grant of the ISO or  within  one year  after  the  transfer  of the
     shares to the optionee,  the holder of the shares  immediately prior to the
     disposition  shall  promptly  notify the Company in writing of the date and
     terms of the disposition and shall provide such other information regarding
     the  disposition  as the Company may require.  Such holder shall pay to the
     Company any withholding and employment  taxes which the Company in its sole
     discretion  deems  applicable to such  disposition.  Any disposition not in
     accordance  with this  Section  6.3.3  shall be void and of no effect.  The
     Company  may  instruct  its shares  transfer  agent by  appropriate  means,
     including  placement  of legends  or stock  certificates,  not to  transfer
     shares  acquired by  exercise  of an ISO unless it has been  advised by the
     Company that the requirements of this Section 6.3.3 have been satisfied.

          6.3.4  Withholding and Employment  Taxes. At such time or times as the
     Administrator  determines,  at or following the time of exercise of an ISO,
     the  optionee  shall  remit to the  Company in cash all  federal  and state
     withholding  and  employment  taxes  which  the  Administrator  in its sole
     discretion deems applicable to the exercise of an ISO or the disposition of
     shares acquired by such exercise. The Administrator may, in the exercise of
     the Administrator's sole discretion,  permit an optionee to pay some or all
     of  such  taxes  by  means  of a  promissory  note  on  such  terms  as the
     Administrator deems appropriate.

<PAGE>

7.   Manner Of Exercise.

     An optionee  wishing to exercise an Option shall give written notice to the
Company at its principal  executive  office,  accomplished  by an executed stock
purchase  agreement  in form and  substance  satisfactory  to the Company and by
payment of the exercise price as provided in Section 6.1.7. The date the Company
receives written notice of an exercise hereunder  accomplished by payment of the
exercise  price  will be  considered  as the date  such  Option  was  exercised.
Promptly after receipt of written  notice of exercise of an option,  the Company
shall  allot and  issue  the  shares  in  respect  of which the  option is being
exercised  and deliver to the  optionee or such other  person a  certificate  or
certificates for the requisite number of shares.  An optionee shall not have any
privileges as shareholder with respect to any shares covered by the Option until
the date of allotment and issuance of the shares.

8.   Employment Relationship.

     Nothing in this Plan or any Option granted  hereunder  shall interfere with
or limit in any way the  right of the  Company  or of any of its  Affiliates  to
terminate  an  optionee's  employment  or status as a director at any time,  nor
confer  upon any  optionee  any  right to  continue  in the  employ  of, or as a
director of, the Company or any of its Affiliates.

9.   Amendment, Suspension, Or Termination of This Plan.

     The Board may at any time amend, alter,  suspend, or discontinue this Plan,
except to the extent that  shareholder  approval is required by applicable  law;
provided,  however,  no amendment,  alteration,  suspension,  or discontinuation
shall be made that  would  impair  the  rights of any  grantee  under any Option
theretofore  granted,  without the grantee's  consent.  The Board shall have the
power  to  make  such  changes  in  this  Plan  and  in  the   regulations   and
administrative  provisions  hereunder  or in any  outstanding  Option and in the
opinion of counsel for the Company may be necessary or appropriate  from time to
time to  enable  any  Option  granted  pursuant  to this Plan to  qualify  as an
incentive  stock option under Section 422A of the Code,  subject in al events to
the consent of the holder of such Option.  However,  in the event of a change of
control of the voting shares or the sale of  substantially  all of the assets of
the Company,  all Options issued under this Plan shall become  immediately  100%
