Liability of such Party in all prior periods, is less than it would have been if
such Income Tax Liability  were  determined  without regard to such Tax Item. In

deemed to create Tax Benefit in the year of such Final  Determination (and in no
other year) in an amount equal to the total  amount of the present  value of the
present and future  anticipated tax reductions from such Tax Item,  applying for
this  purpose an  assumption  that the Tax Item will be  absorbed in full as and
when it first becomes deductible or creditable under applicable law and applying
for this purpose a discount rate equal to the prevailing five-year United States
Treasury rate (as published in the Wall Street Journal) plus 105 basis points as
of the date of such Final  Determination.  A Tax Item that results in additional
tax basis to a  non-depreciable,  non-amortizable  asset shall not be treated as
resulting in a Tax Benefit until a reduction in Income Tax Liability is actually
realized on a Tax Return.

     1.49 "Tax Detriment"  shall mean an increase in the Income Tax Liability of
a Party to this Agreement (or any member of the Affiliated  Group of which it is
a  member)  for  any  taxable  period.  Except  as  otherwise  provided  in this
Agreement,  a Tax  Detriment  shall be deemed to have been  realized or suffered
from a Tax Item in a taxable  period,  only if and to the extent that the Income
Tax Liability of the Party (or any member of the Affiliated Group of which it is
a member) for such period,  after taking into account the effect of the Tax Item
on the Income Tax Liability of such Party in all prior periods,  is greater than
it would have been if such Income Tax Liability were  determined  without regard
to such Tax Item.

     1.50 "Tax  Item"  shall  mean any item of income,  gain,  loss,  deduction,
credit,  recapture  of  credit,  or any other  item which may have the effect of

commencing  on or before the  September 1, 2000 and ending on December 31, 2000;

estimated tax, information statements and returns relating to, or required to be

returns or reports  with  respect to backup  withholding  and other  payments to
third Parties.

Detriment to the other Party.  Subject to the provisions of this Agreement,  all
decisions  relating to the  preparation of Tax Returns shall be made in the sole
discretion of the Party responsible under this Agreement for such preparation.


                                       10

Section 5.        SHARING OF INCOME TAXES.

     5.1 General Tax Sharing  Principles.  Controlled  shall pay to Distributing
(and shall indemnify and hold harmless  Distributing  against) the  Consolidated
Tax Amount at such times and in such  amounts  specified in Sections 5.2 and 5.3
hereof.

     5.2 Estimated Payments.  No later than 5 days prior to the date on which an
estimated  Federal  Income Tax  installment  or an  estimated  State  Income Tax
installment of the  Distributing  Group is due,  Controlled  shall determine the
Estimated Tax Amount. No later than the Federal Income Tax estimated tax payment
date for any Tax Period or the State Income Tax  estimated  tax payment date for
any Tax Period,  as the case may be,  Controlled  shall pay to Distributing  the
Estimated Tax Amount.

     5.3   Payment of Taxes After Year-End.

     (a)  No later than 15 days prior to the due date  (including all applicable
          and  valid  extensions)  for  the  Distributing  Group's  consolidated
          Federal  Income  Tax  Return  for each Tax  Period,  Controlled  shall
          deliver  to  Distributing  a pro forma  Federal  Income  Tax Return of
          Controlled  reflecting  Controlled's  Consolidated Tax Amount for such
          Tax Period prepared by Controlled in good faith. Each pro forma return
          prepared by  Controlled  shall  include the  information  required for
          subsidiaries  pursuant to Treas.  Reg. Section 1.1502-75 or such other
          information as may be reasonably  requested by Distributing.  No later
          than 15 days prior to the due date (including all applicable and valid
          extensions) for each State Income Tax Return that includes  Controlled
          and  another  member of the  Distributing  Group for each Tax  Period,
          Controlled  shall deliver to Distributing a pro forma State Income Tax
          Return  reflecting  Controlled's  Consolidated Tax Amount for such Tax
          Period prepared by Controlled in good faith. Each pro forma Tax Return
          shall be delivered  together with a statement showing a calculation of
          the amount to be paid pursuant to Section 5.1 hereof.

     (b)  Upon receipt of a pro forma Federal  Income Tax Return or State Income
          Tax Return from Controlled,  Distributing may adjust such return if it
          determines  that  the  calculation  of  the  Consolidated  Tax  Amount
          reflected on such return or returns is incorrect  or  incomplete.  Any
          adjustment  made by  Distributing  under this Section  5.3(b) shall be
          treated  as  though it had  always  been  reflected  on such pro forma
          return.  Controlled  shall  not be  permitted  to invoke  the  dispute
          resolution  procedures in Section 12 of this Agreement  until it shall
          have paid any amounts required under Section 5.1 hereof.

     (c)  No later than the due date for any  Distributing Tax Return to which a
          pro forma Return prepared pursuant to Section 5.3(a) of this Agreement
          is attributable  (i), if the Consolidated Tax Amount reflected on such
          pro forma  Income Tax Return is greater than the  aggregate  Estimated
          Tax Amount paid by Controlled  with respect to such Tax Return and Tax
          Period under Section 5.2 hereof,  Controlled shall pay to Distributing
          an amount equal to the difference  between the Consolidated Tax Amount
          reflected on such pro forma Income Tax Return for the  applicable  Tax
          Period and the aggregate  Estimated Tax Amount paid by Controlled with
          respect to such Tax Return and Tax Period under Section 5.2 hereof; or


                                       11

          (ii),  if the  Consolidated  Tax  Amount  reflected  on such pro forma
          Income Tax Return is less than the aggregate Estimated Tax Amount paid
          by  Controlled  with  respect to such Tax Return and Tax Period  under
          Section 5.2 hereof,  Distributing  shall pay to  Controlled  an amount
          equal to the  difference  between the  aggregate  Estimated Tax Amount
          paid by  Controlled  with  respect  to such Tax  Return and Tax Period
          under Section 5.2 hereof and the  Consolidated Tax Amount reflected on
          such pro forma Income Tax Return for the applicable Tax Period.

     (d)  If a pro forma Tax Return  described in Section 5.3 of this  Agreement
          reflects a Tax Asset that may under  applicable law be used to produce
          a Tax Benefit to Distributing, Distributing shall pay to Controlled an
          amount  equal to the Tax Benefit  produced by such Tax Asset within 30
          days of the realization by  Distributing of such Tax Benefit,  and the
          pro forma Tax Returns of Controlled and other relevant  determinations
          hereunder  shall  thereafter  reflect such use.  Without  limiting the
          generality of the foregoing,  the determination of the Tax Benefit for
          purposes  of this  Section  5.3(d)  shall  take into  account  any net
          decrease in the foreign tax credits and business  credits  which would
          otherwise  have been  available  to, and  usable by, the  Distributing
          Group by reason of the use of such Tax Asset.

     5.4  Consolidated   Overall  Foreign  Losses  and   Consolidated   Separate
Limitation  Losses.  If: (i) an overall foreign loss (as defined in Treas.  Reg.
Section 1.904(f)-1(c)(1)) ("OFL") account is generated in Controlled's pro forma
Tax  Return  calculation  of the  Consolidated  Tax Amount in respect of any Tax
Period,  (ii) such OFL has not been  recaptured by  Controlled  in  Controlled's
calculation of the  Consolidated  Tax Amount for any subsequent Tax Period,  and
(iii)  such  OFL  will  not  be  available   for   recapture   in   Controlled's
post-Distribution actual tax calculation, Controlled shall, on or before the due
date for filing  Controlled's  United States  Federal  income tax return for the
period that includes the  Distribution  Date, pay to Distributing  the amount of
any Tax Detriment  incurred by Distributing as a result of Distributing's  prior
inclusion of such OFL in its calculation of its Consolidated  Federal Income Tax
liability,  plus interest  calculated  thereon at a rate equal to the prevailing
five-year  United States  Treasury rate as published in the Wall Street  Journal
plus 105 basis points from the  Distribution  Date to the date of actual payment
of such  amount.  If pursuant to Treas.  Reg.  Section  1.1502-9  Controlled  is
required  to  succeed to any  portion of a  consolidated  overall  foreign  loss
("COFL")  (as  defined  in  Treas.  Reg.  Section   1.1502-9(b)(3))  account  or
consolidated  separate  limitation  loss  ("CSLL")  (as  defined in Treas.  Reg.
Section  1.1502-9(b)(1))  account,  that was not reflected in its calculation of
the Consolidated Tax Amount for any Tax Period,  Distributing  shall,  within 60
days after the Distribution Date, pay Controlled the amount of any Tax Detriment
incurred by Controlled as a result.

     5.5 Carryback Reporting.  If the Income Taxes of the Distributing Group are
reduced for a taxable period beginning  before the Distribution  Date, by reason
of a  Controlled  Group  loss  or  other  Tax  Asset  arising  on or  after  the
Distribution  Date  (a  "Controlled   Carryback")   Distributing  shall  pay  to
Controlled an amount equal to the portion of the Distributing Tax Reduction that
is attributable to the Controlled Carryback.  If both a Controlled Carryback and
a Distributing loss or other Tax Asset arising on or after the Distribution Date
(a  "Distributing  Carryback")  exists,  the  absorption  rules of  Treas.  Reg.
1.1502-21(b)(1),  shall be applied to determine the portion of the  Distributing
Tax  Reduction  that  is  attributable  to  the  Controlled  Carryback  and  the
Distributing  Carryback,  respectively.  Nothing  herein  shall  require  either


                                       12

Distributing  or  Controlled  to carry back a loss or other Income Tax attribute
that it generates.  Any payment  required  pursuant to this Section 5.5 shall be
made no later  than ten (10)  days  after  the  Distributing  Tax  Reduction  is
actually realized by Distributing.

     5.6 Treatment of  Adjustments.  (a) If any Adjustment of a Tax Item is made
to a Tax Return  relating to Federal or State Taxes of the  Distributing  Group,
after the filing  thereof,  in which income or loss of any  Controlled or any of
its  Subsidiaries is included,  then within 30 days of a Final  Determination of
such Adjustment, Controlled shall pay to Distributing, or Distributing shall pay
to Controlled, as the case may be and as appropriate, (i) the difference between
(A) all payments  actually made,  net of all refunds or recoupments  received or
otherwise  realized,  by  Controlled  or  Distributing,  as the  case may be (or
treated  as such) in  accordance  with the  principles  of this  Section  5 with
respect  to such Tax Item for the Tax  Period or fiscal  period  covered by such
Return,  and (B) all  payments  that  would  have  been  made by  Controlled  or
Distributing,  as the case may be (or  treated as such) in  accordance  with the
principles under this Article 5 with respect to such Tax Item for the Tax Period
or fiscal period covered by such Return taking such  Adjustment into account and
(ii) related penalties and interest.

     5.7 Earnings and Profits. Except as otherwise specifically provided herein,
pre-Distribution earnings and profits shall be allocated in accordance with Code
Section 312(h) and Treas. Reg. Section 1.312-10(b).

Section 6.        AUDITS AND TAX CONTROVERSIES AND ADJUSTMENTS.

     6.1 Audit Responsibility and Control.  Except as otherwise provided in this
Agreement,  Distributing shall have sole responsibility for and control over all
audits,  appeals or  litigation  with  respect to any  Income Tax  Returns  that
include periods through August 31, 2000, whether or not those periods constitute
fiscal  periods,  and any Tax  Return  that it is  required  to file  under this
Agreement.  Controlled  shall  have sole  responsibility  and  control  over all
audits, appeals or litigation with respect to any Tax Return that it is required
to file under this Agreement.

     6.2  Notice;  Contest.  Whenever  Distributing  or  Controlled  receives in
writing from the IRS or any other taxing authority notice of an Adjustment which
may  give  rise  to a  payment  from  the  other  Party  under  this  Agreement,
Distributing  or  Controlled  (as the  case may be)  shall  give  notice  of the
Adjustment to the other Party within 10 business days of becoming  aware of such
receipt, but in no case less than 30 days before Distributing or Controlled,  as
the case may be, is  required to respond to the IRS or other  taxing  authority.
The  Indemnifying  Party shall,  at its cost and expense,  have control over all
matters  with  respect  to which such  Party has an  indemnification  or payment
obligation  pursuant  to this  Agreement.  The  foregoing  notwithstanding,  the
Indemnified Party and its  representatives,  at the Indemnified Party's expense,
shall be entitled to participate in all conferences,  meetings,  and proceedings
with  respect  thereto and shall be entitled  to consult  with the  Indemnifying
Party with respect to all such matters. If the IRS or any other taxing authority
proposes to disallow any of the  deductions  required to be taken by a member of
the  Distributing  or Controlled  Group pursuant to Section 7 of this Agreement,
Distributing  or  Controlled,  as the case may be, shall  contest such  proposed
disallowance,  or shall  cause  such  disallowance  to be  contested  to a Final
Determination unless otherwise agreed by the Parties in writing.


                                       13

     6.3 Consultation with Controlled. Distributing may consult with Controlled,
and Controlled agrees to fully cooperate with Distributing,  in the negotiation,
settlement,  or  litigation  of any  liability  for  taxes of any  member of the
Distributing Group regardless of the effect of any such negotiation, settlement,
or litigation on the liability for taxes of any member of the Controlled Group.

     6.4   Consultation   with   Distributing.   Controlled   may  consult  with
Distributing, and Distributing agrees to fully cooperate with Controlled, in the
negotiation,  settlement, or litigation of any liability for taxes of any member
of the  Controlled  Group  regardless  of the  effect  of any such  negotiation,
settlement,  or  litigation  on the  liability  for  taxes of any  member of the
Distributing Group.

     6.5  Cooperation  and  Exchange  of  Information  for  Audits,  Appeals and
Litigation.  The parties  shall  cooperate  and exchange  information  needed to
respond to audits,  appeals and litigation in accordance  with the provisions of
Section 10 of this Agreement.

     6.6 Certain Adjustments. Except as otherwise provided in this Agreement, if
a  Final  Determination  with  respect  to  any  Tax  Item  (including,  without
limitation,  any Tax Item relating to depreciation or amortization) of one Party
(the "First  Party")  results in a Tax Detriment to the First Party and, if as a
result of such Final Determination, (i) the other Party becomes entitled to take
a reporting  position with respect to the same Tax Item that may result in a Tax
Benefit to such other Party, on an appropriate Tax Return,  including an amended
Tax  Return,  or (ii) the other Party has  already  taken a  reporting  position
consistent with such Final  Determination on an appropriate tax return,  and, in
the case of both (i) and  (ii),  such  reporting  position  will  result  in the
realization  of a Tax Benefit for the other Party,  then such other Party shall,
within 30 days after notification and documentation of such Final Determination,
pay to the First Party the aggregate amount of such Tax Detriment (not including
interest or penalties)  suffered by the First Party but limited to an amount not
greater than the Tax Benefit to be realized by the other Party.  For purposes of
this  Section,  Party  may  refer to any  member  of the  Distributing  Group or
Controlled Group.

     Section 7. TAXABILITY AND REPORTING OF STOCK OPTIONS.  Each of Distributing
and Controlled  shall be responsible for making all reports  required to be made
to any relevant tax  authority  with respect to any grants or exercises of stock
options  with  respect  to  their  respective   stocks.   Distributing  (or  the
appropriate  member of the  Distributing  Group)  shall take all tax  deductions
arising by reason of  exercises  of such stock  options  to  purchase  shares of
Distributing  stock.  Controlled  (or the  appropriate  member of the Controlled
Group)  shall take all tax  deductions  arising by reason of  exercises of stock
options  to  purchase  shares  of  Controlled  stock.  If,  pursuant  to a Final
Determination, all or any part of a tax deduction taken pursuant to this Section
7 is  disallowed  to  Distributing,  then,  to the extent  permitted by law, the
appropriate  member of the  Controlled  Group  shall take such  deduction.  If a
member of the Controlled  Group receives a Tax Benefit in any period as a result
of any deduction taken by a member of the Controlled Group in respect of options
exercised against  Distributing  stock,  Controlled shall pay the amount of such
Tax Benefit to Distributing.  If, pursuant to a Final Determination,  all or any
part of a tax  deduction  taken  pursuant  to this  Section 7 is  disallowed  to
Controlled,  then, to the extent permitted by law, the appropriate member of the
Distributing  Group shall take such deduction.  If a member of the  Distributing
Group receives a Tax Benefit in any period as a result of any deduction taken by
a member of the  Distributing  Group in  respect of  options  exercised  against
Controlled  stock,  Distributing  shall pay the  amount of such Tax  Benefit  to
Controlled.


                                       14

     Section  8.  LIABILITY  OF  CONTROLLED   GROUP  FOR   UNDERTAKING   CERTAIN
TRANSACTIONS.  Controlled  shall,  and shall cause each member of the Controlled
Group to, comply with each  representation and statement made, or to be made, to
any taxing authority.  Controlled represents that at no time during the two-year
period preceding the Distribution Date, has Controlled had any plan,  agreement,
arrangement,  substantial  negotiation,  or  other  intention  to  enter  into a
transaction (or series of related  transactions)  whereby a person or entity, or
persons or entities acting in concert,  would acquire greater than 50 percent of
the vote or value of any class of stock of  Controlled,  or more than 50 percent
of Controlled's assets, in each case within the meaning of Section 355(e) of the
Code.  Controlled shall indemnify and hold Distributing harmless against any Tax
or other loss arising from  Controlled's  breach of any  representation  in this
Section 8 or if it takes any action that causes  Distributing  to have liability
with respect to the  Distribution  under Section  355(e) of the Code,  provided,
however, that Controlled shall not be considered in breach of any representation
or to have caused  Distributing  liability  under Section  355(e) of the Code if
such liability would not have arisen but for actions taken by Distributing  with
respect to which Controlled had no actual  knowledge prior to Controlled  taking
its  action or  entering  into a  definitive  agreement  with  respect  thereto.
Distributing  shall, and shall cause each member of the  Distributing  Group to,
comply with each  representation  and written  statement made, or to be made, to
any taxing authority. Distributing shall reasonably cooperate with Controlled to
provide  information  sufficient to allow  Controlled to analyze or  determinate
whether  Distributing's  activities  could  contribute  to cause  Controlled  to
trigger a liability under Section 355(e) of the Code.

Section 9.        INDEMNIFICATION.

     9.1 Timing in General.  Unless otherwise  specified in this Agreement,  all
indemnification  and other payments to be made pursuant to this Agreement  shall
be made  within 30 days of written  notice of a request for  indemnification  or
payment  by the  Indemnified  Party,  which  notice  shall be  accompanied  by a
computation of the amount due.

     9.2  Special  Timing  Rules.  If any  indemnification  or other  payment is
required  to be made under  Section 5 and Section 6 of this  Agreement  upon the
actual or deemed  realization by the Indemnifying  Party of a Tax Benefit,  such
payment  shall be made no later than 30 days after the earlier of (a) the filing
or (b) the due date  (including  extensions)  of the Tax Return with  respect to
which such Tax Benefit is realized. The Parties shall cooperate in good faith in
enforcing the  provisions of this Section 9.2, which  cooperation  shall include
the provision of reasonable access to the Tax Returns of the Indemnifying  Party
by the Indemnified Party in order to determine the amount of any indemnification
or other payment to be made pursuant to this Section 9.2.

     9.3 Interest.  Except as otherwise  specifically  provided  herein,  if any
indemnification  payment  required to be made pursuant to this  agreement is not
made  when  due,  such  payment  shall  bear  interest  at a rate  equal  to the
prevailing five-year United States Treasury rate as published in the Wall Street
Journal plus 105 basis points.

     9.4 Treatment of Tax Indemnity and Tax Benefit Payments.  In the absence of
any change in tax treatment under the Code or other  applicable Tax Law, any Tax
indemnity  payments or Tax Benefit payments made by a Party under this Agreement
shall  be  reported  for  Tax  purposes  by  the  payor  and  the  recipient  as
distributions or capital  contributions,  as appropriate,  occurring immediately


                                       15

before the Distribution, but only to the extent the payment does not relate to a
Tax allocated to the payor in accordance with Treas.  Reg. Section  1.1502-33(d)
(or under corresponding principles of other applicable Tax Laws).

     9.5 Tax Gross Up. If,  notwithstanding  the  manner in which Tax  indemnity
payments and Tax Benefit  payments were reported,  there is an adjustment to the
Tax  liability  of a Party as a result of its  receipt of a payment  pursuant to
this Agreement,  such payment shall be appropriately adjusted so that the amount
of such payment,  reduced by the amount of all Income Taxes payable with respect
to the receipt  thereof  (but taking into account all  correlative  Tax Benefits
resulting from the payment of such Income Taxes),  shall equal the amount of the
payment which the party  receiving  such payment would  otherwise be entitled to
receive pursuant to this Agreement.

     9.6  Interest  Under  This  Agreement.  Anything  herein  to  the  contrary
notwithstanding, to the extent an Indemnifying Party makes a payment of interest
to an Indemnified Party under this Agreement with respect to the period from the
date that the Indemnified  Party made a payment of Tax to a Tax authority to the
date that the Indemnifying  Party reimbursed the Indemnified  Party for such Tax
payment, or with respect to the period from the date that the Indemnifying Party
received a Tax  Benefit to the date  Indemnifying  Party paid the Tax Benefit to
the Indemnified Party, the interest payment shall be treated as interest expense
to the  Indemnifying  Party  (deductible  to the extent  provided by law) and as
interest  income by the  Indemnified  Party  (includible in income to the extent
provided by law).

Section 10.       COOPERATION AND EXCHANGE OF INFORMATION

     10.1 Information from  Controlled.  Controlled  shall, and shall cause each
appropriate member of the Controlled Group to, provide (at Controlled's cost and
expense)  Distributing  with all  information  and other  assistance  reasonably
requested by  Distributing  to enable the members of the  Distributing  Group to
prepare and file the Tax Returns  required or authorized to be filed by them for
any Tax Period pursuant to this Agreement and to respond to audits,  appeals and
litigation  with  respect to such  Returns to the extent  that  Distributing  is
responsible for such audits under Section 6 of this Agreement.

     10.2 Information  from  Distributing.  Distributing  shall, and shall cause
each appropriate member of the Distributing Group to, provide (at Distributing's
cost  and  expense)   Controlled  with  all  information  and  other  assistance
reasonably requested by Controlled to enable the members of the Controlled Group
to file the Tax Returns  required to be filed by them pursuant to this Agreement
and to respond to audits, appeals and ligitation with respect to such Returns to
the extent that  Controlled  is  responsible  for such audits under Section 6 of
this Agreement.

     10.3 Tax Return Information.  Within 5 days before filing a Tax Return that
affects the  liability or the  determination  of the  liability for Taxes of any
member of the  Controlled  Group by a member  of the  Distributing  Group,  such
member of the  Distributing  Group shall provide  Controlled with a copy of only
that portion of such Tax Return which is relevant to the Controlled Group.

     10.4  General  Cooperation.  Distributing  and  Controlled  agree  to fully
cooperate with each other in connection  with the preparation of all Tax Returns


                                       16
required to be filed by them and in connection with responses to audits, appeals
and litigation  with respect to such Returns  consistent  with the assignment of
responsibility  for audits under Section 6 of this Agreement.  Such  cooperation
shall include making personnel and records available promptly and within 20 days
(or such other  period as may be  reasonable  under the  circumstances)  after a
request for such  personnel  or records is made by the taxing  authority  or the
other Party. If any member of Distributing Group or the Controlled Group, as the
case may be, unreasonably fails to provide any information  required pursuant to
this  Section,  then the  requesting  Party  shall  have the  right to engage an
independent   certified   public   accountant  of  its  choice  to  gather  such
information.  Distributing  or Controlled,  as the case may be, agrees to permit
any such independent  certified public  accountant full access to the Tax Return
information  in the  possession  of any  member  of the  Distributing  Group  or
Controlled Group, as the case may be, during  reasonable  business hours, and to
reimburse  or pay  directly  all  costs  and  expenses  in  connection  with the
engagement of such independent certified public accountant.

     10.5  Indemnification.  Distributing shall indemnify and hold harmless each
member of the Controlled  Group and its officers and  employees,  and Controlled
shall indemnify and hold harmless each member of the Distributing  Group and its
officers and employees,  against any cost, fine,  penalty,  or other expenses of
any kind attributable to the negligence of a member of the Distributing Group or
the  Controlled  Group,  as the case may be, in  supplying a member of the other
group  with  inaccurate  or  incomplete  information,  in  connection  with  the
preparation of any Tax Return.

     10.6 Controlled  Payroll and  Unemployment  Compensation  Taxes For Periods
Ending On or After the Distribution  Date.  Distributing shall make available to
Controlled  sufficient data to facilitate a determination of the desirability of
the transfer to the Controlled  Group of any payroll tax  experience  and/or any
favorable unemployment  compensation tax experience rating of Distributing;  and
at Controlled's  election,  Distributing shall cooperate to effect a transfer of
such payroll tax  experience  and/or such  favorable  unemployment  compensation
experience  rating  (including  state  unemployment  reserves) to the Controlled
Group  within one  hundred  and twenty  (120)  days after  Controlled's  written
request therefor.

     10.7  Research  Tax  Credit   Information.   Upon   Controlled's   request,
Distributing  will timely furnish to Controlled the base period  information the
Controlled Group will need,  pursuant to Code Section 41 and similar statements,
to properly compute its research tax credits for years beginning after or on the
Distribution Date.

Section 11.       RETENTION OF RECORDS.

     11.1 General.  Distributing  and Controlled agree to retain the appropriate
records  which may affect the  determination  of the  liability for taxes of any
member of the Distributing  Group or the Controlled Group,  respectively,  until
such time as there has been a Final Determination with respect to such liability
for taxes.

     11.2 Notice of Waivers.  Distributing and Controlled will notify each other
in writing of any waivers or extensions of the applicable statute of limitations
that may affect the period for which any materials,  records,  or documents must
be retained.

Section 12.  RESOLUTION OF DISPUTES.  The Parties  hereto shall attempt in good
faith to resolve any dispute  arising out of, or relating to, this  Agreement (a


                                       17

"Dispute")  and shall  attempt in good faith to  negotiate a  settlement  of any
Dispute.  If,  after the filing of any Tax  Return  under  this  Agreement,  the
Parties  hereto are unable to resolve any  disagreement  or Dispute  relating to
such Tax Return or the  calculation  of any payment under this  Agreement,  such
Dispute shall be submitted for  resolution  by the certified  public  accounting
firms  then  acting  as  independent   auditors  of  each  of  Distributing  and
Controlled. If the independent auditors cannot agree to a resolution,  then such
Dispute shall be submitted for resolution by a third certified public accounting
firm to be  appointed  by mutual  agreement  of the  independent  auditors.  Any
decision by such third certified public  accounting firm shall be binding on the
Parties to this Agreement without further recourse.

Section  13.  TERMINATION  OF  PRIOR  INTERCOMPANY  TAX  ALLOCATION  AGREEMENTS.
Immediately  prior to the close of  business  on the  Distribution  Date (i) all
written or oral agreements or any other  arrangements  relating to allocation of

     14.1 Term of the Agreement. This Agreement shall become effective as of the
date of its execution and, except as otherwise expressly provided herein,  shall
continue in full force and effect until the expiration of the latest  applicable
statute of limitations period.

     14.2 Severability. If any term, provision, covenant, or restriction of this
Agreement is held by a court of competent  jurisdiction to be invalid,  void, or
unenforceable,   the  remainder  of  the  terms,   provisions,   covenants,  and
restrictions  set forth herein shall remain in full force and effect,  and shall
in no way be affected,  impaired,  or invalidated.  It is hereby  stipulated and
declared to be the  intention of the Parties  that they would have  executed the
remaining terms,  provisions,  covenants, and restrictions without including any
of such which may be hereafter declared invalid, void, or unenforceable.  In the
event that any such term,  provision,  covenant,  or  restriction  is held to be
invalid, void, or unenforceable, the Parties hereto shall use their best efforts
to find and employ an alternate means to achieve the same or  substantially  the
same  result  as  that  contemplated  by  such  term,  provision,  covenant,  or
restriction.

     14.3 Assignment.  Except by operation of law or in connection with the sale
of all or substantially  all the assets of a Party hereto,  this Agreement shall
not be assignable,  in whole or in part,  directly or  indirectly,  by any Party
hereto without the advance written  consent of the other Party;  and any attempt
to assign any rights or obligations  arising under this  Agreement  without such


                                       18

consent shall be void; provided,  however, that the provisions of this Agreement
shall be binding  upon,  inure to the  benefit  of, and be  enforceable  by, the
Parties hereto and their respective successors and permitted assigns.

     14.4 Further  Assurances.  Subject to the  provisions  hereof,  the Parties
hereto shall make, execute,  acknowledge, and deliver such other instruments and
documents,  and take all such other  actions,  as may be reasonably  required in
order to  effectuate  the  purposes  of this  Agreement  and to  consummate  the
transactions  contemplated hereby. Subject to the provisions hereof, each of the
Parties shall, in connection  with entering into this Agreement,  performing its
obligations  hereunder and taking any and all actions  relating  hereto,  comply
with all applicable laws, regulations,  orders, and decrees, obtain all required
consents  and  approvals  and make all required  filings  with any  governmental
agency,  other  regulatory  or  administrative  agency,  commission  or  similar
authority,  and promptly  provide the other Parties with all such information as
they may reasonably request in order to be able to comply with the provisions of
this sentence.

     14.5 Parties in Interest. Except as herein otherwise specifically provided,
nothing in this  Agreement  expressed or implied is intended to confer any right
or benefit  upon any person,  firm,  or  corporation  other than the Parties and
their respective successors and permitted assigns.

     14.6  Waivers,  Etc.  No  failure  or delay on the part of the  Parties  in
exercising any power or right hereunder  shall operate as a waiver thereof,  nor
shall  any  single  or  partial  exercise  or any such  right or  power,  or any
abandonment or discontinuance of steps to enforce such right or power,  preclude
any other or further  exercise  thereof or the  exercise  of any other  right or
power.  No modification or waiver of any provision of this Agreement nor consent
to any departure by the Parties therefrom shall in any event be effective unless
the same shall be in writing, and then such waiver or consent shall be effective
only in the specific instance and for the purpose for which given.

     14.7  Setoff.  All  payments to be made by any Party  under this  Agreement
shall be made without setoff,  counterclaim,  or  withholding,  all of which are
expressly waived.

     14.8 Change of Law. If, due to any change in applicable  law or regulations
or their  interpretation  by any  court of law or other  governing  body  having
jurisdiction  subsequent  to the  date of  this  Agreement,  performance  of any
provision of this Agreement or any transaction contemplated thereby shall become
impracticable or impossible,  the Parties hereto shall use their best efforts to
find and employ an alternative  means to achieve the same or  substantially  the
same result as that contemplated by such provision.

     14.9  Confidentiality.  Subject to any contrary  requirement of law and the
right of each Party to enforce its rights  hereunder in any legal  action,  each
Party agrees that it shall keep strictly confidential,  any information which it
or any of its  employees or agents may require  pursuant to, or in the course of
performing its obligations  under,  any provision of this  Agreement;  provided,
however,  that the Parties hereby consent to disclosure of this Agreement to the
IRS in  connection  with any ruling  request made or to be made  relating to the
Distribution.
