                  EMPLOYEE RETENTION AGREEMENT


      THIS EMPLOYEE RETENTION AGREEMENT (the "Agreement") by  and
between  GEODYNAMICS CORPORATION, a California  corporation  (the
"Company")  and PAUL HENRIKSON (the "Employee"), is entered  into
on the date hereinafter set forth.

      The  Board  of Directors of the Company (the  "Board")  has
determined  that it is in the best interests of the  Company  and
its  shareholders  to  assure that  the  Company  will  have  the
continued   dedication  of  the  Employee,  notwithstanding   the
possibility,  threat  or occurrence of a Change  in  Control  (as
hereinafter  defined) of the Company.  The Board believes  it  is
imperative to diminish the inevitable distraction of the Employee
by  virtue of the personal uncertainties and risks created  by  a
pending  or  threatened  Change  in  Control,  to  encourage  the
Employee's full attention and dedication to the Company currently
and  in the event of any threatened or pending change in control,
and to provide the Employee with compensation arrangements upon a
Change  in  Control  which provide the Employee  with  individual
financial security and which are competitive with those of  other
corporations.  In order to accomplish these objectives, the Board
has  caused the Company to enter into this Agreement.   Should  a
Change  of  Control  occur  because of a  Management  Buyout  (as
hereinafter defined), then this Agreement will have no  force  or
effect.  This Agreement will automatically expire on May 1,  1996
if no Change in Control occurs by that time.

     1.   CERTAIN DEFINITIONS

           (a)   The  "Effective Date" shall be  the  first  date
     during the "Change in Control Period" (as defined in Section
     1(b)  below) on which a Change in Control occurs.   Anything
     in  this Agreement to the contrary notwithstanding,  if  the
     Employee's  employment with the Company is terminated  prior
     to  the date on which a Change in Control occurs, and it  is
     reasonably  demonstrated that such termination  was  at  the
     request  of  a  third party who has taken  steps  reasonably
     calculated to effect a Change in Control or otherwise  arose
     in  connection  with  or  in anticipation  of  a  Change  in
     Control,  then  for  all  purposes of  this  Agreement,  the
     Effective Date shall mean the date immediately prior to  the
     date of such termination.

           (b)   The  "Change in Control Period"  is  the  period
     commencing  on the Effective Date and ending  on  the  first
     anniversary of such date.

           (c)  A "Change in Control" shall occur or be deemed to
     have  occurred  only if any of the following  events  occur:
     (i) any "person", as such term is used in Sections 13(d) and
     14(d)  of  the Securities Exchange Act of 1934,  as  amended
     (the "Exchange Act") (other than the Company, any trustee or
     other fiduciary holding securities under an employee benefit
     plan  of  the Company, or any corporation owned directly  or
     indirectly   by   the  stockholders  of   the   Company   in
     substantially  the  same proportion as  their  ownership  of
     stock  of the Company) is or becomes the "beneficial  owner"
     (as  defined in Rule 13d-3 under the Exchange Act), directly
     or  indirectly,  of  securities of the Company  representing
     twenty percent (20%) or more of the combined voting power of
     the  Company's then outstanding securities (other than as  a
     result of acquisitions of such securities from the Company);
     (ii) individuals who, as of the date hereof, constitute  the
     Board  (as of the date hereof, the "Incumbent Board")  cease
     for  any  reason  to constitute at least a majority  of  the
     Board,   provided  that  any  person  becoming  a   director
     subsequent  to the date hereof whose election or  nomination
     for election by the Company's shareholders was approved by a
     vote of at least a majority of the directors then comprising
     the Incumbent Board (other than an election or nomination of
     an  individual  whose initial assumption  of  office  is  in
     connection  with  an actual or threatened  election  contest
     relating to the election of the Directors of the Company (as
     such  terms  are  used  in  Rule 14a-11  of  Regulation  14A
     promulgated  under the Exchange Act) shall be, for  purposes
     of  this Agreement, considered as though such person were  a
     member  of  the Incumbent  Board; (iii) the stockholders  of
     the Company approve a merger or consolidation of the Company
     with  any  other  corporation, other than (A)  a  merger  or
     consolidation which would result in the voting securities of
     the Company outstanding immediately prior thereto continuing
     to  represent (either by remaining outstanding or  by  being
     converted  into  voting securities of the surviving  entity)
     more  than fifty percent (50%) of the combined voting  power
     of  the  voting securities of the Company or such  surviving
     entity   outstanding  immediately  after  such   merger   or
     consolidation or (B) a merger or consolidation  effected  to
     implement  a  recapitalization of the  Company  (or  similar
     transaction)  in which no "Person" (as hereinafter  defined)
     acquires  more  than twenty percent (20%)  of  the  combined
     voting  power of the Company's then outstanding  securities;
     or  (iv)  the stockholders of the Company approve a plan  of
     complete liquidation of the Company or an agreement for  the
     sale  or  disposition by the Company of all or substantially
     all of the Company's assets.

           (d)  A "Management Buyout" shall occur when there  has
     been a Change of Control in which the Employee shall hold  a
     significant financial interest or management position.

     2.   EMPLOYMENT PERIOD

           The Company hereby agrees to continue the Employee  in
its  employ  and,  subject to Section 5(d) hereof,  the  Employee
hereby  agrees  to remain in the employ of the Company,  for  the
period  commencing on the Effective Date and ending on the  first
anniversary of such date (the "Employment Period").

     3.   TERMS OF EMPLOYMENT

          (a)  Position and Duties

                (i)   During  the  Employment  Period:   (A)  the
     Employee's  position (including status, offices, titles  and
     reporting     requirements),    authority,    duties     and
     responsibilities  shall  be  at least  commensurate  in  all
     material  respects with the most significant of those  held,
     exercised  and assigned at any time during the  ninety  (90)
     day  period immediately preceding the Effective Date and (B)
     the  Employee's services shall be performed at the  location
     where  the  Employee was employed immediately preceding  the
     Effective Date, or any office or location less than  fifteen
     (15)  miles from such location and less than ten (10)  miles
     in  commuting distance further than the Employee's commuting
     distance  to  the  location at which the Employee  performed
     such services prior to the Change in Control.

                (ii)  During the Employment Period, and excluding
     any periods of vacation and sick leave to which the Employee
     is  entitled,  the  Employee  agrees  to  devote  reasonable
     attention  and  time  during normal business  hours  to  the
     business  and  affairs  of  the  Company  and  to  use   the
     Employee's reasonable best efforts to perform faithfully and
     efficiently  such responsibilities.  During  the  Employment
     Period,  it  shall not be a violation of this Agreement  for
     the  Employee to (A) serve on corporate, civic or charitable
     boards or committees; (B) deliver lectures, fulfill speaking
     engagements  or teach at educational institutions;  and  (C)
     manage  personal investments, so long as such activities  do
     not  significantly  interfere with the  performance  of  the
     Employees' responsibilities as an employee of the Company in
     accordance  with this Agreement.  It is expressly understood
     and  agreed that to the extent that any such activities have
     been  conducted by the Employee prior to the Effective Date,
     the continued conduct of such activities (or the conduct  of
     activities  similar in nature and scope thereto)  subsequent
     to  the  Effective Date shall not thereafter  be  deemed  to
     interfere   with   the   performance   of   the   Employee's
     responsibilities to the Company.

          (b)  Compensation

               (i)    Base Salary.  During the Employment Period,
     the  Employee shall receive an annual base salary (the "Base
     Salary"), payable biweekly, at a weekly rate at least  equal
     to  the  highest weekly Base Salary paid or payable  to  the
     Employee by the Company during the twelve (12) month  period
     immediately preceding the month in which the Effective  Date
     occurs,  with  an annual increase in salary consistent  with
     the increases, if any, received for current periods over the
     previous annual calendar twelve (12) months.

                (ii)    Incentive, Savings and Retirement  Plans.
     In  addition to Base Salary payable as hereinabove provided,
     the  Employee  shall  be  entitled  to  receive  cash  sales
     incentives  and to participate during the Employment  Period
     in  all  other  incentive,  savings  and  retirement  plans,
     practices,  policies and programs applicable  to  other  key
     employees of the Company and its subsidiaries (including the
     Company's  employee  benefit plans, in each  case  providing
     benefits  which  are  the economic equivalent  to  those  in
     effect  or as subsequently amended).  Such plans, practices,
     policies  and programs, in the aggregate, shall provide  the
     Employee    with   compensation,   benefits    and    reward
     opportunities at least as favorable as the most favorable of
     such   compensation,   benefits  and  reward   opportunities
     provided  by the Company for the Employee under such  plans,
     practices,  policies and programs as in effect at  any  time
     during the ninety (90) day period immediately preceding  the
     Effective  Date  or, if more favorable to the  Employee,  as
     provided  at any time thereafter with respect to  other  key
     employees of the Company.

                (iii)      Welfare  Benefit  Plans.   During  the
     Employment   Period,  the  Employee  and/or  the  Employee's
     family,   as  the  case  may  be,  shall  be  eligible   for
     participation  in  and  shall  receive  all  benefits  under
     welfare  benefit  plans, practices,  policies  and  programs
     provided  by  the  Company (including,  without  limitation,
     medical,    prescription,   dental,    disability,    salary
     continuance, employee life, group life, accidental death and
     travel  accident insurance plans and programs), at least  as
     favorable  as  the most favorable of such plans,  practices,
     policies  and  programs in effect at  any  time  during  the
     ninety  (90) day period immediately preceding the  Effective
     Date  or,  if  more  favorable to the  Employee  and/or  the
     Employee's family, as in effect at any time thereafter  with
     respect to other key employees of the Company.

                (iv)    Expenses.  During the Employment  Period,
     the   Employee   shall  be  entitled   to   receive   prompt
     reimbursement  for all reasonable expenses incurred  by  the
     Employee  in  accordance with the most  favorable  policies,
     practices  and  procedures of the Company in effect  at  any
     time during the ninety (90) day period immediately preceding
     the Effective Date or, if more favorable to the Employee, as
     in  effect at any time thereafter with respect to other  key
     employees of the Company.

                (v)     Fringe  Benefits.  During the  Employment
     Period,  the  Employee shall be entitled to fringe  benefits
     and perquisites in accordance with the most favorable plans,
     practices, programs and policies of the Company in effect at
     any  time  during  the  ninety (90) day  period  immediately
     preceding  the Effective Date or, if more favorable  to  the
     Employee,  as in effect at any time thereafter with  respect
     to  other  key  employees of the Company, but  not  less  in
     dollar value than the Employee's present fringe package.

                (vi)    Office  and  Support Staff.   During  the
     Employment  Period, the Employee shall  be  entitled  to  an
     office  or offices of a size and with furnishings and  other
     appointments,  and to secretarial and other  assistance,  at
     least  equal to the most favorable of the foregoing provided
     to  the  Employee by the Company at any time during the  one
     hundred  eighty (180) day period immediately  preceding  the
     Effective  Date  or, if more favorable to the  Employee,  as
     provided  at any time thereafter with respect to  other  key
     employees of the Company.

               (vii)     Vacation.  During the Employment Period,
     the   Employee  shall  be  entitled  to  paid  vacation   in
     accordance with the most favorable plans, policies, programs
     and practices of the Company as in effect at any time during
     the   ninety  (90)  day  period  immediately  preceding  the
     Effective Date or, if more favorable to the Employee, as  in
     effect  at  any time thereafter with respect  to  other  key
     employees  of  the Company, and will pay all fees  or  costs
     incurred  to  protect  and  uphold  all  aspects   of   said
     agreement.

                 (viii)      Indemnity  Agreement.   During   the
     Employment Period, the Company shall keep in full force  and
     effect,  and  shall not purport to amend or  terminate,  any
     existing  indemnity agreement between the Employee  and  the
     Company.

          (c)  Payment in Lieu of Retaining Employee.  In lieu of
     retaining  the  Employee during the  Employment  Period  (or
     portion  thereof), the Company may pay to  the  Employee  an
     amount  equal to seventy-five percent (75%) of (b)(i)  above
     for a period of twelve (12) months to be paid on the date of
     termination of employment.  This payment is in excess of the
     amount due under the severance pay policy of the Company.

     4.   TERMINATION

            (a)   Death  or  Disability.   This  Agreement  shall
     terminate automatically upon the Employee's death.  If as  a
     result of incapacity due to physical or mental illness,  the
     Employee   shall  have  been  absent  from   the   full-time
     performance  of the Employee's duties with the  Company  for
     six  (6)  consecutive months, and within  thirty  (30)  days
     after  written  notice  of  termination  is  given  to   the
     Employee, the Employee shall not have returned to the  full-
     time  performance of the Employee's duties,  the  Employee's
     employment   may   be   terminated  for   "Disability"   (as
     hereinafter defined).  Any termination for Disability  under
     this Agreement shall not affect any rights the Employee  may
     otherwise  have.  If the Company determines  in  good  faith
     that  the  Disability of the Employee has occurred (pursuant
     to  the definition of "Disability" set forth below), it  may
     give  the  Employee  written  notice  of  its  intention  to
     terminate  the  Employee's employment.  In such  event,  the
     Employee's  employment  with  the  Company  shall  terminate
     effective on the thirtieth (30th) day after receipt of  such
     notice  by  the Employee (the "Disability Effective  Date"),
     provided,  that,  within the thirty  (30)  days  after  such
     receipt,  the Employee shall not have returned to  full-time
     performance of the Employee's duties.

           (b)   Cause.  The Company may terminate the Employee's
     employment  for  "Cause."  For purposes of  this  Agreement,
     "Cause"  shall  mean  termination (A)  upon  the  Employee's
     willful  and continued failure to substantially perform  the
     Employee's  with the Company up to his or her  normal  skill
     level (performance of the past) (other than any such failure
     resulting from the Employee's incapacity due to physical  or
     mental  illness  or  any such actual or anticipated  failure
     after  the  issuance  of  a Notice  of  Termination  by  the
     Employee,  provided  that a written demand  for  substantial
     performance  has  been  delivered to  the  Employee  by  the
     Company  specifically identifying the manner  in  which  the
     Company  believes  that the Employee has  not  substantially
     performed  the  Employee's duties and the Employee  has  not
     cured  such  failure  within ninety  (90)  days  after  such
     demand; (B) the Employee's willful violation of any material
     provision  of any confidentiality, nondisclosure, assignment
     of  invention,  noncompetition or similar agreement  entered
     into  by  the  Employee in connection  with  the  Employee's
     employment  by the Company.  For purposes of this paragraph,
     no  act  or failure to act on the Employee's part  shall  be
     deemed  "willful" unless done by the Employee  not  in  good
     faith and without the Employee's reasonable belief that  the
     Employee's  action was in the best interest of the  Company;
     or  (C) other than specifically identified herein, no  other
     termination   is  without  full  compensation   within   the
     Employee's  Employment Agreements for the life of  the  same
     without contest.

           (c)   Notice of Termination.  Any termination  by  the
     Company for Cause or by the Employee for any reason shall be
     communicated  by  Notice  of  Termination  (as   hereinafter
     defined) to the other party hereto given in accordance  with
     Section  12(b)  of  this Agreement.  For  purposes  of  this
     Agreement, a "Notice of Termination" means a written  notice
     which  (i)  indicates the specific termination provision  in
     this  Agreement relied upon, (ii) sets forth  in  reasonable
     detail  the  facts and circumstances claimed  to  provide  a
     basis for termination of the Employee's employment under the
     provision  so indicated and (iii) if the Date of Termination
     (as defined below) is other than the date of receipt of such
     notice  specifies the termination date (which date shall  be
     not  more  than fifteen (15) days after the giving  of  such
     notice.

           (d)  Date of Termination.  "Date of Termination" means
     the  date  of  receipt of the Notice of Termination  or  any
     later  date specified therein, as the case may be; provided,
     however, that (i) if the Employee's employment is terminated
     by  the Company other than for Cause or Disability, the Date
     of  Termination  shall  be the date  on  which  the  Company
     notifies  the Employee of such termination and (ii)  if  the
     Employee's  employment is terminated by reason of  death  or
     Disability,  the Date of Termination shall be  the  date  of
     death  of the Employee or the Disability Effective Date,  as
     the case may be.

     5.   OBLIGATIONS OF THE COMPANY UPON TERMINATION

          (a)  Death.  If the Employee's employment is terminated
     by  reason  of  the Employee's death, this  Agreement  shall
     terminate without further obligation to the Employee's legal
     representatives  under  this  Agreement,  other  than  those
     obligations accrued or earned and vested (if applicable)  by
     the  Employee  as  of  the Date of  Termination.   All  such
     Accrued  Obligations shall be paid to the Employee's  estate
     or  beneficiary, as applicable, in a lump sum in cash within
     thirty  (30)  days of the Date of Termination.  Anything  in
     this   Agreement   to  the  contrary  notwithstanding,   the
     Employee's  family shall be entitled to receive benefits  at
     least  equal to the most favorable benefits provided by  the
     Company  to  surviving families of employees of the  Company
     under  such plans, programs, practices and policies relating
     to  family  death benefits, if any, in accordance  with  the
     most  favorable plans, programs, practices and  policies  of
     the Company in effect at any time during the ninety (90) day
     period immediately preceding the Effective Date or, if  more
     favorable  to the Employee and/or the Employee's family,  as
     in  effect on the date of the Employee's death with  respect
     to other key employees of the Company and their families.

           (b)   Disability.   If  the Employee's  employment  is
     terminated  by  reason  of the Employee's  Disability,  this
     Agreement shall terminate without further obligations to the
     Employee, other than those obligations accrued or earned and
     vested  (if  applicable) by the Employee as of the  Date  of
     Termination,  including  for  this  purpose,   all   Accrued
     Obligations.  All such Accrued Obligations shall be paid  to
     the  Employee in a lump sum in cash within thirty (30)  days
     of  the Date of Termination.  Anything in this Agreement  to
     the   contrary  notwithstanding,  the  Employee   shall   be
     entitled,  after the Disability Effective Date,  to  receive
     disability  and other benefits at least equal  to  the  most
     favorable  of  those  provided by the  Company  to  disabled
     employees  and/or  their families in  accordance  with  such
     plans,   programs,  practices  and  policies   relating   to
     disability,  if  any, in accordance with the most  favorable
     plans,  programs, practices and policies of the  Company  in
     effect  at  any  time  during the  ninety  (90)  day  period
     immediately   preceding  the  Effective  Date  or,  if  more
     favorable  to the Employee and/or Employee's family,  as  in
     effect  at  any time thereafter with respect  to  other  key
     employees of the Company and their families.

           (c)   Cause.   If the Employee's employment  shall  be
     terminated for Cause, this Agreement shall terminate without
     further   obligations  to  the  Employee,  other  than   the
     obligation  to pay those obligations accrued or  earned  and
     vested  (if applicable) by the Employee through the Date  of
     Termination, plus the amount of any accrued vacation pay and
     any   compensation  previously  deferred  by  the   Employee
     (together with accrued interest thereon).

           (d)   Other Than for Cause, Death or Disability.   If,
     during  the  Employment Period, the Company shall  terminate
     the  Employee's employment other than for Cause,  Disability
     or  death,  or if the Employee shall terminate  his  or  her
     employment   for  any  reason,  the  payment  described   in
     Paragraph 3(c) shall be made.

     6.   NON-EXCLUSIVITY OF RIGHTS

           Nothing  in this Agreement shall prevent or limit  the
Employee's  continuing or future participation  in  any  benefit,
bonus,  stock  option, stock purchase incentive or  other  plans,
programs, policies or practices, provided by the Company  or  any
of  its subsidiaries and for which the Employee may qualify,  nor
shall  anything herein limit or otherwise affect such  rights  as
the  Employee may have under any stock option or other agreements
with  the Company or any of its subsidiaries.  Amounts which  are
vested  benefits or which the Employee is otherwise  entitled  to
receive  under  any  plan, policy, practice  or  program  of  the
Company, or any of its subsidiaries, at or subsequent to the Date
of  Termination, shall be payable in accordance with  such  plan,
policy, practice or program.

     7.   FULL SETTLEMENT

           The Company's obligation to make the payments provided
for  in  this Agreement, and otherwise to perform its obligations
hereunder,  shall  not be affected by any set-off,  counterclaim,
recoupment,  defense or other claim, right or  action  which  the
Company  may  have against the Employee or others.  In  no  event
shall the Employee be obligated to seek other employment or  take
any  other action by way of mitigation of the amounts payable  to
the Employee under any of the provisions of this Agreement.



     8.   ENFORCEMENT OF RIGHTS

          (a)  Any dispute or controversy between the Company and
     the  Employee  which the parties are unable  to  resolve  by
     negotiation  shall  be settled exclusively  by  arbitration,
     conducted  before  a  panel of one  (1)  arbitrator  in  Los
     Angeles, California, or at the direction of the Employee, in
     accordance  with  the  rules  of  the  American  Arbitration
     Association then in effect.  Judgment may be entered on  the
     arbitrator's award in any court having jurisdiction.

           (b)   The Company shall pay to the Employee all  legal
     fees  and  expenses incurred by the Employee as a result  of
     any  dispute under this Agreement (including all  such  fees
     and  expenses, if any, incurred in contesting  or  disputing
     any  such termination or in seeking to obtain or enforce any
     right or benefit provided by this Agreement or in connection
     with  any tax audit or proceeding to the extent attributable
     to  the  application of Section 4999 of the Internal Revenue
     Code  of  1986,  as amended (the "Code") to any  payment  or
     benefit provided hereunder).

     9.   CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY

           (a)   Anything  in  this  Agreement  to  the  contrary
     notwithstanding,  in the event it shall be  determined  that
     any payment (within the meaning of Section 380G(b)(2) of the
     Code)  or distribution by the Company to or for the  benefit
     of  the Employee, whether paid or payable or distributed  or
     distributable  pursuant to the terms of  this  Agreement  or
     otherwise  (a "Payment") would be subject to the excise  tax
     imposed  by  Section 4999 of the Code, or  any  interest  or
     penalties  to the Employee, with respect to such excise  tax
     (such  excise  tax,  together with  any  such  interest  and
     penalties, are hereinafter collectively referred to  as  the
     "Excise  Tax"),  then  the Employee  shall  be  entitled  to
     receive an additional payment under this Agreement (a "Gross-
     Up  Payment")  in an amount such that after payment  by  the
     Employee  of all taxes (including any interest or  penalties
     imposed  with respect to such taxes), including  any  Excise
     Tax, imposed upon the Gross-Up Payment, the Employee retains
     an  amount  of the Gross-Up Payment equal to the Excise  Tax
     imposed upon the Payments.

           (b)   Subject to the provisions of Section  9(c),  all
     determinations  required to be made under  this  Section  9,
     including  whether a Gross-Up Payment is  required  and  the
     amount of such Gross-Up Payment, shall be made by AA and Co.
     (the   "Accounting  Firm")  which  shall  provide   detailed
     supporting  calculations both to  the  Company  and  to  the
     Employee  within thirty (30) business days of  the  Date  of
     Termination,  if  applicable, or such  earlier  time  as  is
     requested by the Company.  The initial Gross-Up Payment,  if
     any,  as determined pursuant to this Section 9(b), shall  be
     paid to the Employee within five (5) days of the receipt  of
     the Accounting Firm's determination.  If the Accounting Firm
     determines that no Excise Tax is payable by the Employee, it
     shall  furnish the Employee with an opinion that failure  to
     report  the Excise Tax on the Employee's applicable  federal
     income  tax  return  would not result in the  imposition  of
     negligence  or  similar penalty.  Any determination  by  the
     Accounting  Firm shall be binding upon the Company  and  the
     Employee.  As a result of the uncertainty in the application
     of  Section  4999  of the Code at the time  of  the  initial
     determination  by  the  Accounting  Firm  hereunder,  it  is
     possible  that  Gross-Up Payments which will not  have  been
     made  by the Company should have been made ("Underpayment"),
     consistent  with  the  calculations  required  to  be   made
     hereunder.   In  the  event that the  Company  exhausts  its
     remedies  pursuant to Section 9(c) below, and  the  Employee
     thereafter  is required to make payment of any  Excise  Tax,
     the  Accounting  Firm  shall determine  the  amount  of  the
     Underpayment  that  has occurred and any  such  Underpayment
     shall  be promptly paid by the Company to or for the benefit
     of the Employee.

           (c)   The Employee shall notify the Company in writing
     of  any  claim  by  the Internal Revenue  Service  that,  if
     successful, would require the payment by the Company of  the
     Gross-Up Payment.  Such notification shall be given as  soon
     as  practicable,  but no later than ten (10)  business  days
     after  the  Employee knows of such claim and shall  appraise
     the  Company  of the nature of such claim and  the  date  on
     which  such  claim  is requested to be paid.   The  Employee
     shall  not  pay  such claim prior to the expiration  of  the
     thirty (30) day period following the date on which it  gives
     such notice to the Company (or such shorter period ending on
     the  date  that  any payment of taxes with respect  to  such
     claim  is  due).   If the Company notifies the  Employee  in
     writing  prior  to  the expiration of such  period  that  it
     desires to contest such claim, the Employee shall:

                (i)   give the Company any information reasonably
     requested by the Company relating to such claim;

                 (ii)   take  such  action  in  connection   with
     contesting  such  claim  as  the  Company  shall  reasonably
     request  in  writing, from time to time, including,  without
     limitation, accepting legal representation with  respect  to
     such  claim  by  an  attorney  reasonably  selected  by  the
     Company;

               (iii)  cooperate with the Company in good faith in
     order to effectively contest such claim; and

                (iv)  permit  the Company to participate  in  any
     proceedings relating to such claim.

     Provided,  however,  that the Company  shall  bear  and  pay
     directly   all  costs  and  expenses  (including  additional
     interest  and  penalties) incurred in connection  with  such
     contest  and shall indemnify and hold the Employee harmless,
     on  an  after-tax basis, for any Excise Tax or  income  tax,
     including  interest  and  penalties  with  respect  thereto,
     imposed  as  a result of such representation and payment  of
     costs  and  expenses.  Without limitation on  the  foregoing
     provisions  of this Section 9(c), the Company shall  control
     all  proceedings taken in connection with such contest  and,
     at  its  sole  option,  may pursue or  forego  any  and  all
     administrative    appeals,   proceedings,    hearings    and
     conferences  with the taxing authority in  respect  of  such
     claim  and  may,  at  its  sole option,  either  direct  the
     Employee  to  pay  the tax claimed and  sue  for  refund  or
     contest  the  claim  in  any  permissible  manner,  and  the
     Employee agrees to prosecute such contest to a determination
     before  any  administrative tribunal, in a court of  initial
     jurisdiction  and in one or more appellate  courts,  as  the
     Company  shall  determine; provided, however,  that  if  the
     Company  directs the Employee to pay such claim and sue  for
     refund, the Company shall advance the amount of such payment
     to  the  Employee,  on  an interest-free  basis,  and  shall
     indemnify  and hold the Employee harmless, on  an  after-tax
     basis, from any Excise Tax or income tax, including interest
     or  penalties with respect thereto, imposed with respect  to
     such  advance  or  with respect to any imputed  income  with
     respect  to  such  advance; and further  provided  that  any
     extension of the statute of limitations relating to  payment
     of  taxes for the taxable year of the Employee with  respect
     to  which  such contested amount is claimed  to  be  due  is
     limited  solely to such contested amount.  Furthermore,  the
     Company's control of the contest shall be limited to  issues
     with  respect to which a Gross-Up Payment would  be  payable
     hereunder  and the Employee shall be entitled to  settle  or
     contest, as the case may be, any other issue raised  by  the
     Internal Revenue Service or any other taxing authority.

          (d)  If, after the receipt by the Employee of an amount
     advanced by the Company pursuant to Section 9(c) above,  the
     Employee becomes entitled to receive any refund with respect
     to  such claim, the Employee shall (subject to the Company's
     complying  with  the requirements of Section 9(c))  promptly
     pay  to the Company the amount of such refund (together with
     any interest paid or credited thereon after taxes applicable
     thereto).   If,  after the receipt by  the  Employee  of  an
     amount  advanced by the Company pursuant to Section 9(c),  a
     determination  is  made  that  the  Employee  shall  not  be
     entitled to any refund with respect to such claim,  and  the
     Company  does  not  notify the Employee in  writing  of  its
     intent  to  contest  such  denial or  refund  prior  to  the
     expiration of sixty (60) days after such determination, then
     such advance shall be forgiven and shall not be required  to
     be  repaid  and the amount of such advance shall offset,  to
     the extent thereof, the amount of Gross-Up  Payment required
     to be paid.

     10.  CONFIDENTIAL INFORMATION

          The Employee shall hold in a fiduciary capacity for the
benefit  of  the Company all secret or confidential  information,
knowledge  or  data  relating  to the  Company,  or  any  of  its
subsidiaries, and their respective businesses, which  shall  have
been obtained by the Employee during the Employee's employment by
the  Company, or any of its subsidiaries, and which shall not  be
or become public knowledge (other than by acts by the Employee or
his  or  her  representatives in violation  of  this  Agreement).
After  termination of the Employee's employment with the Company,
the  Employee shall not, without the prior written consent of the
Company,  communicate or divulge any such information,  knowledge
or  data to anyone other than the Company and those designated by
it.  In no event shall an asserted violation of the provisions of
this  Section 10 constitute a basis for deferring or  withholding
any   amounts  otherwise  payable  to  the  Employee  under   the
Agreement.

     11.  SUCCESSORS

           (a)   This Agreement is personal to the Employee  and,
     without the prior written consent of the Company, shall  not
     be  assignable by the Employee otherwise than by will or the
     laws  of  descent  and distribution.  This  Agreement  shall
     inure to the benefit of and be enforceable by the Employee's
     legal representatives.

           (b)  This Agreement shall inure to the benefit of  and
     be binding upon the Company and its successors and assigns.

           (c)   The  Company will require any successor (whether
     direct  or  indirect, by purchase, merger, consolidation  or
     otherwise)  to  all  or substantially all  of  the  business
     and/or  assets of the Company to assume expressly and  agree
     to perform this Agreement in the same manner and to the same
     extent that the Company would be required to perform  it  if
     no  such  successor  had  taken  place.   As  used  in  this
     Agreement,  "Company" shall mean the Company as hereinbefore
     defined  and any successor to its business and/or assets  as
     aforesaid which assumes and agrees to perform this Agreement
     by operation of law or otherwise.

     12.  MISCELLANEOUS

           (a)  This Agreement shall be governed by and construed
     in  accordance  with  the laws of the State  of  California,
     without  reference to principles of conflict of  laws.   The
     captions  of  this Agreement are not part of the  provisions
     hereof  and  shall have no force or effect.  This  Agreement
     may  not  be amended or modified otherwise than by a written
     agreement executed by the parties hereto or their respective
     successors and legal representatives.

           (b)   All  notices and other communications  hereunder

     or  to  such  other  address  as  either  party  shall  have
     furnished  to  the other in writing in accordance  herewith.
     Notice  and communications shall be effective when  actually
     received by the addressee.

            (c)   The  invalidity  or  unenforceability  of   any
     provision of this Agreement shall not affect the validity or
     enforceability of any other provision of this  Agreement  or
     any  other  agreements by and between the  Company  and  the
     Employee.

           (d)  The Company may withhold from any amounts payable
     under  this Agreement such federal, state or local taxes  as
     shall  be required to be withheld pursuant to any applicable
     law or regulation.

           (e)   The  Employee's failure to  insist  upon  strict
     compliance with any provision hereof shall not be deemed  to
     be  a  waiver  of  such  provision or  any  other  provision
     thereof.

           (f)   This Agreement contains the entire understanding
     of  the Company and the Employee with respect to the subject
     matter   hereof,  and  the  Employee  waives  any  severance
     benefits  (but not pension benefits) that he  or  she  might
     otherwise be entitled to under other Company employee plans,
     excluding such provisions as may be contained in the form of
     Severance Agreement as may be in effect between the Employee
     and the Company.

           (g)   The  Employee and the Company acknowledge  that,
     except  as  provided  by  any other  agreement  between  the
     Employee and the Company, the employment of the Employee  by
     the  Company is "at will", and, prior to the Effective Date,
     may  be terminated by either the Employee or the Company  at
     any  time.   Upon a termination of the Employee's employment
     or  upon  the  Employee's ceasing to be an  officer  of  the
     Company,  in  each case, prior to the Effective Date,  there
     shall be no further rights under this Agreement.

     IN WITNESS WHEREOF, the Employee has hereunto set his or her
hand  and,  pursuant  to  the authorization  from  its  Board  of
Directors,  the Company has caused these presents to be  executed
in  its  name  on  its  behalf  all,  as  of  the  10th  day  of
August, 1995.
