     1. Sponsorship.

          (a)  In  consideration  of  the  payments,  through  the  issuance  of
securities  to AJR as provided for in Section 3 hereof,  AJR agrees to designate
XC as an associate sponsor and the "exclusive  technology  sponsor" for wearable
computer  technology" of the Team for the Season and grants to XC the rights and
benefits of such sponsorship as more fully set forth herein.

          (b) In order to publicly  reflect this  sponsorship and provide the XC
with the goodwill  associated  with the  sponsorship,  AJR shall  provide and XC
shall receive,  throughout the Term (as  hereinafter  defined) of this Agreement
the following:

                (i)     an XC logo shall be  prominently  displayed on the front
                        hoods  and rear  quarters  of the two (2) Le Mans  level
                        Porsche racing cars (the "Cars"), which will be raced by
                        Team throughout the Season,

                (ii)    a large XC logo  will be  prominently  displayed  on the
                        transporter vehicles for the Cars,

                (iii)   an XC logo shall be displayed  on the  dashboard of each
                        Car in a  prominent  and  conspicuous  place so that the
                        logo will be visible to




                        any in-car  camera which may be located in either of the
                        Cars.  XC  acknowledges   that  the   installation   and
                        operation of an in-car  camera is not within the control
                        of, or guaranteed by, AJR, and

                (iv)    XC logo patches (which will be furnished by XC) shall be
                        worn on a prominent  place on the uniforms of all of the
                        crew and Team members.

     The size and placement of the XC logos,  as mutually  agreed upon by XC and
AJR,  shall be the same size and placement as appearing in the first race of the
Season on the Cars, transport vehicles and crew uniforms. XC shall have approval
rights  over  use of its logo by AJR and  shall  designate  which  XC  trademark
identifications are utilized by AJR and how they are used in connection with the
logos.  The  costs  and  expenses  of  placing  the  XC  logos  on the  Cars  as
contemplated  by subsections  (ii), (ii) and (iii) of this Section 1(b) shall be
borne exclusively by AJR.

          (c) In  addition  to the logo  placements  described  in Section  1(b)
hereof,  as part of the  sponsorship  granted  hereby,  during  the Term of this
Agreement,  XC shall  also  receive  and AJR shall  provide,  at AJR's  cost and
expense (except as otherwise expressly provided), the following:

                        one (1) promotional event to be designated by XC.

                (ii)    If requested by XC, XC shall have the right to host XC's
                        employees  and  invitees  at a  hospitality  tent at the
                        various  race venues  during the Season,  the details of
                        each  hospitality  event to be  agreed  to by XC and AJR
                        (such details to include, without limitation, the amount
                        of costs to be paid by XC, the  drinks and food  service
                        at the event,  seating, the availability of VIP parking,
                        etc.).

                (iii)   If  requested by XC, in its sole  discretion,  AJR shall
                        make one of the drivers of the Cars  available to attend
                        promotional and media events hosted by XC; provided that
                        XC shall pay for the reasonable  out-of-pocket costs and
                        expenses  incurred by AJR in making the driver available
                        for such events.

                (iv)    AJR  shall  provide  a link  from  its  website  to XC's
                        website,  such  linking  to be  accomplished  as soon as
                        possible after the date of this Agreement. AJR shall not
                        make any  reference  to XC on its website (or modify any
                        approved reference) without XC's prior written approval.

                (v)     AJR  shall use its best  efforts  to  promote  the name,
                        image,  brand and  reputation of XC and the products and
                        services  of XC. In  addition,  AJR  shall  assist XC in
                        evaluating various applications of wearable and wireless
                        devices  to  automobile   racing   including

                                      -2-


                        potential  applications  for the use of  devices  at the
                        track,  in the pits,  in the  stands and  generally  for
                        crowd control.

                (vi)    Subject to the prior approval of Porsche,  XC shall have
                        the right to use  photographs  of the Cars,  the drivers
                        and  other   Team   members  in   connection   with  the
                        preparation  of  promotional  and  marketing  materials,
                        without paying any royalty or other fee. If clearance or
                        approvals are required to be obtained in connection with
                        the use of such photographs,  AJR shall use commercially
                        reasonable   efforts  to  obtain  such   clearances  and
                        approvals. The extent of the approvals to be sought from
                        the drivers  and other Team  members  shall  include the
                        right to use their name,  likeness,  approved  biography
                        and  sobriquet in  connection  with such  marketing  and
                        promotional materials.


     2. Other Rights of XC. During the Term of this Agreement, XC shall have the
right to identify  itself  with the Team and to  identify  itself as an official
"technology  sponsor for  wearable  computers"  of the Team in any  promotional,
marking or other materials used by XC.


     3. Consideration to AJR; Registration Rights.

          (a) In  consideration of the rights granted to XC pursuant to Sections
1 and 2 hereof and the provisions of this  Agreement,  XC shall issue to AJR (i)
125,000  shares  (the  "Shares")  of common  stock,  par value  $0.01 of XC (the
"Common  Stock");  and (ii)  warrants to purchase  50,000 shares of Common Stock
(the  "Warrants").  The Warrants shall have an exercise price of $1.18 per share
being the closing  market price for the Common Stock on April 30, 2002 and shall
be exercisable for a period of three (3) years from their date of issue.

          (b) In  addition  to the  Shares  and  Warrants  to be  issued  to AJR
pursuant to Section 3(a)  hereof,  XC agrees to provide to AJR five (5) to eight
(8) (as  determined by XC in its  discretion)  MAV(R)  wearable  computers  (the
"Units") to be used by AJR to promote XC's products and services as contemplated
by Section 1(c)(v). AJR shall have no liability for any damage to or loss of the
wearable computers issued to AJR under this Agreement, except to the extent such
damage  or loss  results  from the  intentional  abuse of the  equipment  by AJR
personnel.

          (c) XC shall provide a link from its website to AJR's website.

          (d) XC  hereby  grants to AJR  "piggyback"  registration  rights  with
respect to the Shares and the shares of Common  Stock  underlying  the  Warrants
(collectively,  the  "Registrable  Securities").  Pursuant  to such  "piggyback"
registration  rights, XC shall include all of the Registrable  Securities in any
registration  statement filed by XC with respect to its Common Stock (other than
on a  registration  statement  on Forms  S-8 or S-4 (or any  successors  to such
forms) or relating to any employee  stock option plan) with the  Securities  and
Exchange Commission.  In the event a registration  statement covering all of the
Registrable  Securities  has



                                      -3-


not been filed with the Securities and Exchange  Commission on or before July 1,
2002, XC agrees to pay to AJR $10,000. XC shall pay to AJR an additional $10,000
for each thirty-day  period  thereafter  (e.g.,  ending,  August 1, September 1,
etc.) in which a  registration  statement has not been filed with the Securities
and Exchange Commission for purposes of registering all Registrable  Securities.
All such  payments  due  hereunder  shall be payable on or before the 5th of the
month in which such payment  becomes due. In the event XC voluntarily  withdraws
any registration  statement submitted to the Securities and Exchange Commission,
XC shall be deemed to have  never  submitted  such  registration  statement  for
purposes of this paragraph.  Unless  otherwise agreed by XC and AJR, none of the
Registrable  Securities shall be sold as part of an underwritten public offering
in connection with the registration  statement filed pursuant to this paragraph,
but, instead, shall be delivered to AJR as unrestricted, freely trading Shares.

          (e) All costs and expenses  associated  with the  registration  of the
Registrable  Securities  shall be born by  XC.AJR  shall  provide  XC with  such
information  regarding AJR as XC shall request for inclusion in the registration
statement  and shall  indemnify the Company and hold it harmless with respect to
any material misstatement or material omission with respect to such information

          (f) All Registrable Securities that are registered pursuant to Section
3(d) hereof shall be subject to the "lock-up"  provided for in this Section 3(f)
(the  "Lock-Up"),  and AJR agrees to be bound by the  Lock-Up.  Pursuant  to the
Lock-Up,  AJR agrees that following the registration of Registrable  Securities,
it shall not directly or  indirectly,  sell,  transfer,  pledge,  assign,  gift,
hypothecate  or  otherwise  dispose of more than 25,000  shares of Common  Stock
during  any  five  (5)  consecutive  trading  days on the  principal  securities
exchange or securities market where XC's Common Stock is then traded.

     4. Accredited Investor Representations.  In order to induce XC to issue the
Shares and the  Warrants to AJR,  AJR hereby  represents  and  warrants to XC as
follows:

          (a) AJR is aware of what constitutes an "accredited  investor" as that
term is defined under Regulation D promulgated under the Securities Act of 1933,
as amended (the  "Securities  Act"), and under applicable state securities laws,
and AJR represents and warrants that is an "accredited investor" for purposes of
Regulation D and such state securities laws.

          (b) AJR acknowledges that an investment in the Shares and the Warrants
is a  speculative  investment  and  involves a high degree of risk,  and that XC
makes no assurances  whatsoever  concerning the present or prospective  value of
the  Shares  or the  Warrants.  AJR is able to bear  the  economic  risks  of an
investment in the Shares and the Warrants,  and, consequently,  without limiting
the generality of the foregoing, is able to hold the Shares and the Warrants for
an indefinite period of time and has a sufficient net worth to sustain a loss of
its entire  investment  in the Shares and the  Warrants in the event such a loss
should occur.

          (c) AJR has had an opportunity to review copies of XC's public filings
with  the  United  States   Securities  and  Exchange   Commission  (the  "SEC")
(collectively,  the "Public  Documents").  AJR has had the opportunity to obtain
any additional  information  necessary to verify the accuracy of the information
contained in the Public  Documents  and has been given the  opportunity  to meet
with representatives of XC and to have them answer any questions and



                                      -4-


provide any  additional  information  considered  relevant by AJR. In making its
decision  to invest in Shares and the  Warrants,  AJR has  relied  solely on the
Public Documents.

          (d) AJR is acquiring the Shares and the Warrants for AJR's own account
for  investment  and not with a view to or for  resale  in  connection  with any
distribution  of the  Shares or the  Warrants.  AJR has not  offered or sold any
portion of the Shares or the Warrants  and has no present  intention of dividing
the Shares or the Warrants with others or of selling,  distributing or otherwise
disposing of any portion of the Shares or the Warrants either currently or after
the passage of a fixed or determinable  period of time or upon the occurrence or
non-occurrence of any predetermined event or circumstance.  AJR is acquiring the
Shares and the Warrants for AJR's own account for investment and not with a view
to or for  resale  in  connection  with any  distribution  of the  Shares or the
Warrants.  AJR has not offered or sold any portion of the Shares or the Warrants
and has no present  intention of dividing the Shares or the Warrants with others
or of selling,  distributing or otherwise disposing of any portion of the Shares
or the Warrants either currently or after the passage of a fixed or determinable
period of time or upon the  occurrence or  non-occurrence  of any  predetermined
event or  circumstance.  Nothing in this Section 4(d) shall limit the ability of
the AJR to sell or transfer any of the Shares  following the  effectiveness of a
registration  statement  concerning  the Shares in accordance  with Section 3(d)
hereof.

          (e) AJR  understands  that the issuance of the Shares and the Warrants
has not been  registered  under the  Securities  Act and that the Shares and the
Warrants have been issued in reliance upon an exemption therefrom for non-public
limited offerings.  AJR acknowledges that the Shares and the Warrants constitute
"restricted  securities"  under  the  Securities  Act and  they may not be sold,
transferred,  assigned,  pledged or otherwise  disposed of, except pursuant to a
registration  statement that is declared  effective under the Securities Act, or
an exemption  from  registration  under the Securities Act as determined by XC's
legal  counsel.  AJR  further  acknowledges  and  agrees  that XC will  place an
appropriate  restrictive  legend  on the  certificates  for the  Shares  and the
Warrants,  as applicable,  to comply with the Securities Act and to identify the
Shares and the Warrants as "restricted securities".

          (f) AJR further acknowledges that no United States federal (including,
without  limitation,  the SEC),  or state agency or similar  agency of any other
country,  has  reviewed,  approved,  passed upon or made any  recommendation  or
endorsement regarding XC or the Shares or the Warrants.

          (g) AJR  acknowledges  that XC is  relying  on the  accuracy  of AJR's
representations  and warranties set forth in Section 4 in issuing the Shares and
the Warrants to AJR.

          (h)  AJR  acknowledges   that  the  certificate  for  the  Registrable
Securities  shall contain such legends as XC shall consider  necessary to ensure
compliance with the restrictions of the Securities Act and with the Lock-Up.

     5. Term. Subject to earlier termination as provided for herein, the term of
this Agreement  shall commence as of the date hereof and shall  terminate at the
end of the Season which is scheduled to end on October 12, 2002 (the "Term").



                                      -5-


     6. Licensed Materials.

          (a) XC does hereby  grant AJR a limited and  non-transferable  license
and  non-exclusive  right to use XC's logo and  trademarks and service marks set
forth on Schedule A attached hereto (the "Licensed  Materials")  during the Term
of this Agreement.  AJR shall only be permitted to use the Licensed Materials in
connection  with  the  Sponsorship  and  only in the  limited  manner  expressly
permitted as set forth on Schedule A attached hereto. No other use of any of the
Licensed  Materials by AJR shall be  permitted.  AJR shall not have the right to
modify,  alter or change any of the Licensed  Materials.  All Licensed Materials
shall remain the sole and exclusive  property of XC and AJR shall not obtain any
right,  title or interest  therein.  AJR shall not have any right to sub-license
any of the Licensed Materials to any third party.

          (b) Upon the  termination  of this  Agreement,  AJR shall  immediately
cease  using any of the  Licensed  Materials  and shall  comply with the written
directions of XC in connection therewith.

          (c) XC  represents  and warrants to AJR that XC has the right to grant
to AJR  the  right  to use  the  Licensed  Materials  as  contemplated  by  this
Agreement.

          (d) AJR shall not use any of the  Licensed  Materials  to  express  or
imply any  endorsement of any other sponsor of the Team by XC. AJR shall not use
any of the Licensed Materials in connection with, or in any way associated with,
the names, marks, trademarks,  servicemarks,  symbols, products, services, logos
or proprietary designations or properties of any third party.

          (e)  Notwithstanding  anything  to the  contrary  herein,  AJR  and/or
Porsche shall be permitted to use  photographs of the Cars,  transport  vehicles
and crew uniforms containing XC logos and Licensed Materials for any promotional
or marketing purposes during and forever after the term of this Agreement.


     7. Reputation. AJR shall not take any action or suffer any action to occur,
whether taken by the Team or others,  which could result in an adverse impact on
XC, its Licensed Materials and the goodwill associated  therewith as a result of
this Agreement.  Neither party shall have the right to use the corporate name of
the other.


     8. Representations and Warranties.

          (a) In order to induce  the  other  party  hereto  to enter  into this
Agreement,  each of XC and AJR hereby represents and warrants to the other party
as follows:  (i) it is duly  organized,  validly  existing and in good  standing
under the laws of the jurisdiction of the state of its incorporation,  with full
power to carry on its business as presently  conducted  and as  contemplated  by
this Agreement and to execute,  deliver and perform this Agreement in accordance
with its terms;  (ii) this Agreement  constitutes  its legal,  valid and binding
obligation,  enforceable  against it in accordance with its terms; and (iii) its
execution,  delivery and  performance  of this  Agreement  does not and will not
conflict with,  violate or breach any of its constituent  documents  (including,
without  limitation,  its articles of incorporation and by-laws) or



                                      -6-


any material  contract or agreement or any decree,  order or judgment or any law
or  regulation  to which it is a party or  subject  or by which it or any of its
properties or assets is bound.

          (b) AJR hereby further represents and warrants to XC as follows:

                (i)     that AJR entering into this  Agreement  does not violate
                        any rule or regulation of the entity and/or organization
                        that oversees the Season; and

                (ii)    AJR shall not make any  representation  or warranty that
                        the Cars are owned by or the property of XC.

     9. Confidentiality Covenant.

          (a)  As  a  consequence  of  this   Agreement  and  the   relationship
established  hereby,  each  party  may  obtain  from  the  other  party  certain
confidential and proprietary  and/or non-public  information with respect to the
other party,  including,  without limitation,  pricing terms, business plans and
prospects,  sales  and  marketing  techniques,   design  concepts,   information
regarding the  development,  composition  and  manufacture  of products,  ideas,
drawings,  product  specifications,  trade and industrial secrets,  intellectual
property rights,  financial  information,  the names and the nature of, business
dealings with, suppliers, customers and others, and the other party's structure,
organization,  commercial and business  affairs and financial  condition and the
other party's trade secrets (collectively "Confidential  Information").  Each of
XC and AJR acknowledges  that the  Confidential  Information it obtains from the
other party hereto  constitutes the trade secrets of the disclosing  party.  AJR
and XC each agrees that it shall keep the  Confidential  Information it receives
from the other party hereto strictly  confidential and shall not disclose any of
the Confidential  Information to any other person or entity,  or take or use any
of the Confidential Information for its own purposes,  except as may be required
in connection with the  performance of its  obligations  under this Agreement or
the enforcement of this Agreement.  Notwithstanding  the foregoing,  a party may
disclose the  Confidential  Information  of the other party hereto:  (i) if such
Confidential  Information  becomes  generally  known or available to the public,
other  than  due to a  breach  of this  Agreement  by the  party  receiving  the
Confidential  Information hereunder;  (ii) in connection with the enforcement of
this  Agreement;  (iii) pursuant to applicable law,  regulation or subpoena;  or
(iv) if such Confidential  Information was disclosed to either AJR or XC, as the
case may be,  by a source  that was not  bound,  to the  knowledge  of the party
receiving the Confidential Information,  to a confidentiality obligation for the
benefit of, or fiduciary  relationship  in favor of, the other party hereto.  In
furtherance of the confidentiality obligations set forth herein, AJR and XC will
adopt and implement appropriate  procedures intended to prevent the unauthorized
disclosure of  Confidential  Information  that it receives from the other party.
The  obligations  of the parties  pursuant to this  Section 9 shall  survive the
expiration or termination of this Agreement.

          (b) In the event  that XC and AJR,  as  applicable,  is  requested  or
required (by deposition,  interrogatory,  request for documents, subpoena, civil
investigative  demand or similar  legal,  judicial or  regulatory  process or as
otherwise  required by  applicable  law or  regulation)  to disclose  any of the
Confidential  Information  of the other  party  hereto,  such  person  shall (i)
provide the other party hereto with prompt prior written  notice of such request
or requirement,



                                      -7-


and (ii)  cooperate  with the  other  party so that the  other  party may seek a
protective  order  or  other  appropriate  remedy  or,  if  appropriate,   waive
compliance  with the terms and provisions of this  Agreement.  In the event that
such protective order or other remedy is not obtained, or the other party waives
compliance with the terms and provisions hereof, each of XC and AJR, as the case
may be, may disclose only that portion of the Confidential Information that such
person is  advised  by legal  counsel  in  writing  is  legally  required  to be
disclosed.

          (c)  Each  of XC and AJR  agree  that  money  damages  would  not be a

                (ii)    Any  representation  or  warranty  made  by AJR in  this

                        the date made; or

                (iii)   AJR  makes  a  general  assignment  for the  benefit  of
                        creditors  or  has  a  custodian,  receiver  or  similar

                (iv)    AJR shall commence any case,  proceeding or other action

                        AJR or its debts under any applicable  law,  domestic or
                        foreign,    relating    to    bankruptcy,    insolvency,
                        reorganization,  dissolution  or  relief of  debtors  or
                        seeking  the   appointment   of  a  receiver,   trustee,
                        custodian or other  similar  official for AJR or for all
                        or a substantial part of its properties or assets; or an
                        involuntary   case,   proceeding   or  other  action  is

                        or inconsistent  with, the limited rights granted to AJR
                        hereunder.

                (vi)    XC reasonably  determines that its continued involvement
                        with AJR or the Term will result in an adverse impact to
                        XC's reputation.

following events (each an "AJR Event of Default"):

                (i)     XC breaches any material term,  provision or covenant of
                        this  Agreement  on the  part  of XC to be  observed  or
                        performed  and such breach is not cured  within ten (10)
                        days after written notice of the breach is given by AJR;
                        or

                (ii)    Any  representation  or  warranty  made  by XC  in  this
                        Agreement shall be materially  false or misleading as of
                        the date made; or

                (iii)   XC  makes  a  general  assignment  for  the  benefit  of
                        creditors  or  has  a  custodian,  receiver  or  similar
                        official  appointed over it or all or substantially  all
                        of its properties or assets; or

                (iv)    XC shall  commence any case,  proceeding or other action
                        seeking  to have an  order  for  relief  entered  on its

                        commenced  against XC by any other party with respect to
                        any  of the  foregoing,  and in  the  case  of any  such

this  Agreement,  applicable  law, in equity or  otherwise  with  respect to the
actions or inactions  that gave rise to the AJR Event of Default or the XC Event
of Default, as the case may be. In addition, upon the occurrence of an AJR Event
of Default any of the Warrants which have not been exercised shall automatically
terminate  and be void and all of the  Shares  and any  shares of  Common  Stock

     11. Indemnification.

          (a) AJR shall  indemnify  each XC  Indemnified  Party and hold each XC

                (i)     any breach by AJR of any of its agreements, covenants or
                        obligations hereunder; or

                (ii)    the use of any of the  Licensed  Materials  in a  manner
                        that is not permitted hereby.

          (b) XC shall  indemnify AJR and its  directors,  officers,  employees,
agents and attorneys and their  respective  successors and assigns (each an "AJR
Indemnified  Party") and to hold each AJR  Indemnified  Party  harmless from and
against any and all Losses  incurred by any AJR Indemnified  Party,  directly or
indirectly, as a result of or based upon, any of the following:

                (i)     any breach by XC of any of its agreements,  covenants or
                        obligations hereunder; or

                (ii)    a claim by any third  party that the  permitted  uses of
                        any of the  Licensed  Materials  hereunder  violates  or
                        infringes   any   of   the    trademarks,    tradenames,
                        servicemarks,   servicenames   or   other   intellectual
                        property rights of such third party.

          (c) Either party seeking  indemnification  under this  Agreement  (the
"Indemnified  Party")  shall  give  notice  to the  party  required  to  provide
indemnification   hereunder  (the  "Indemnifying   Party")  promptly  after  the
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought hereunder,  and the Indemnified Party shall permit the Indemnifying Party
(at the sole cost and expense of the  indemnifying  Party) to assume the defense
of any claim or litigation resulting therefrom;  provided, that: (i) counsel for
the Indemnifying Party who shall conduct the defense of such claim or litigation
shall be reasonably  satisfactory to the Indemnified Party; (ii) the Indemnified
Party may participate in such defense,  but only at the Indemnified  Party's own
cost and expense; and (iii) the omission by the Indemnified Party to give notice
as  provided   herein   shall  not  relieve  the   Indemnifying   Party  of  its
indemnification  obligations hereunder,  except to the extent that such omission
results in a material impairment of the deficiencies to the Claims asserted.

          (d) The  Indemnifying  Party shall not,  except with the prior written
consent  of  the  Indemnified  Party,  consent  to  entry  of  any  judgment  or
administrative  order or enter  into any  settlement  that (i) could  affect the
intellectual  property  rights or other  business  interests of the  Indemnified
Party or (ii) does not include as an  unconditional  term  thereof the giving by
the  claimant  or  plaintiff  to the  Indemnified  Party of a  release  from all
liability with respect to such claim or litigation.

          (e) In the event  that  either  (i) the  Indemnifying  Party  does not
assume the  defense  of the claim  subject  to  indemnification  within ten (10)
business days after  receiving  written notice of the claim from the Indemnified
Party  pursuant  to Section  12(c)  hereof or (ii) the  Indemnified  Party shall
reasonably  and in good faith  determine  that the conduct of the defense of any
claim  subject to  indemnification  hereunder or any proposed  settlement of any
such claim by the  Indemnifying  Party might be expected to affect adversely the
Indemnified  Party's  intellectual  property rights or ability to conduct future
business,  the Indemnified  Party shall have the right at all times to take over
and  assume  control  over the  defense,  settlement,  negotiations  or  lawsuit
relating  to any such  claim at the sole cost and  expense  of the  Indemnifying
Party.



                                      -10-


          (f) For purposes hereof, the term "XC Indemnified Party" shall mean XC

respective successors and assigns.

          (g) For purpose  hereof the term  "Losses"  shall mean  out-of  pocket
costs and expenses.

          (h) Notwithstanding  anything herein to the contrary,  AJR's liability
under  this  Section  11 shall not exceed One  Hundred  Fifty  Thousand  Dollars
($150,000).  In addition,  AJR's  obligations  under  Section  11(a) above shall
survive  for a  period  of one (1)  year  after  the  date  of  this  Agreement.
Thereafter,  AJR's  obligations under Section 11(a) shall terminate and be of no
further force and effect,  except to the extent of any claims made thereunder by
XC  prior  to  such  date,  which  claims  shall  survive.  The  indemnification
obligations  described  in Section  11(a),  including  all  limitations  on such
obligations, shall be the exclusive remedy of the XC Indemnified Parties for any
Losses  resulting from or based upon any breach by AJR of any of its agreements,
covenants or obligations  hereunder or the use of any of the Licensed  Materials
in a manner that is not permitted hereby.

     12. Independent  Entities.  This Agreement is being entered into by two (2)
independent  corporations  and nothing herein shall create a partnership,  joint
venture,  fiduciary or other relationship.  Neither party has the right or shall
represent  to any other  person or entity that it has the right to legally  bind
the other party hereto.

     13.  Force  Majeure.  XC and AJR  shall  not be liable to the other for any
delay or failure to perform its  obligations  hereunder which is principally the
result of the occurrence of an Event of Force Majeure.  In the event of any such
delay or failure,  XC or AJR, as applicable,  shall immediately  furnish written
notice thereof and the reason therefor to the other party. The performance of XC
or AJR, as  applicable  shall be deemed  suspended  so long as and to the extent
that any such Event  Force  Majeure  continues.  XC or AJR,  as the case may be,
shall use its best  efforts to cure or correct  any such Event of Force  Majeure
and  resume  performance  of its duties and  obligations  hereunder,  within the
shortest  period of time  possible.  For  purposes of this  Agreement,  the term
"Event  of Force  Majeure"  shall  mean  any of the  following:  war,  sabotage,
insurrection,  riot,  the act of any  government  (de  facto  or de jure) or any
agency or subdivision thereof,  acts of terrorism,  accident,  fire,  explosion,
flood,  storm,  hurricane or other acts of God or other  similar acts beyond the
reasonable  control of XC or AJR, as the case may be, which  prevents XC or AJR,
as the case may be, from performing its obligations hereunder.

any proceeding to enforce this  Agreement and  unconditionally  and  irrevocably
waive the right to trial by jury in any such action,  suit or other  proceeding.

unenforceable,  the remainder of this  Agreement,  and the  application  of such
term,  provision or condition to persons or circumstances other than those as to
which it is held invalid,  illegal or unenforceable shall be unaffected thereby,

the fullest extent permitted by applicable law.

     19.  Further  Assurances.  The parties  agree to do such  further  acts and

provision  herein  contained  shall be deemed to be a waiver of any preceding or
succeeding  breach  thereof or of any other  agreement,  covenant  or  provision
herein  contained.  Any  waiver  granted  in  accordance  with the terms of this
Agreement shall be limited to the specific  instance and purpose for which it is
granted.
