                                  ESPS, Inc.
                             Employment Agreement

To Henry Hill:

     This Agreement establishes the terms of your employment with ESPS, Inc., a
Delaware corporation (the "Company").

Employment and Duties    You and the Company agree to your employment as Senior
                         Vice President, Client Services on the terms contained
                         herein. You agree to perform whatever duties the
                         Company's Board of Directors (the "Board") or person
                         the Board or the Company's Chief Executive Officer
                         specifies as your direct report (the "Direct Report")
                         may assign you from time to time that are reasonably
                         consistent with your position as Senior Vice President,
                         Client Services. During your employment, you agree to
                         devote your full business time, attention, and energies
                         to performing those duties (except as your Direct
                         Report otherwise agrees from time to time). You agree
                         to comply with the noncompetition, secrecy, and other
                         provisions of Exhibit A to this Agreement.

Term of Employment       Your employment under this Agreement begins as of your
                         execution of this Agreement (the "Effective Date").
                         Unless sooner terminated under this Agreement, your
                         employment ends at 6:00 p.m. Eastern Time on the second
                         anniversary of the Effective Date.

                         The period running from the Effective Date to the
                         second anniversary of the Effective Date in the
                         preceding sentence is the "Term."

                         Termination or expiration of this Agreement ends your
                         employment but does not end your obligation to comply
                         with Exhibit A or the Company's obligation, if any, to
                         make payments

                                                                   Page 1 of 24

                         under the Payments on Termination and Severance
                         provisions as specified below.

Compensation

     Salary              The Company will pay you an annual salary (the
                         "Salary") from the Effective Date at the rate of not
                         less than $180,000 in accordance with its generally
                         applicable payroll practices. The Board or your Direct
                         Report will review your Salary annually and consider
                         you for increases.

     Bonus               You will be eligible for an annual bonus equal to up to
                         $75,000. The Board or your Direct Report will review
                         your bonus annually and consider you for increases.
                         This bonus will be calculated according to annual
                         incentive plan formulas adopted on an annual basis by
                         the Company. It is the Company's good faith intention
                         to provide formulas for future fiscal years within 90
                         days of the commencement of such fiscal year.

     Car Allowance       You will receive a car allowance equal to $500 per
                         month.

     Relocation Expenses In the event the Company relocates your principal place
                         of business in excess of 25 miles, but not more than 50
                         miles from Fort Washington, Pennsylvania, the Company
                         will reimburse you for reasonable and necessary
                         relocation expenses, not to exceed $15,000.

     Vacation            You will be eligible for four weeks vacation per annum.
                         In addition, you will be eligible for personal days and
                         sick days the Company makes generally available from
                         time to time to the Company's employees, as those
                         benefits are amended or terminated from time to time.

     Employee Benefits   While the Company employs you under this Agreement, the
                         Company will provide you with the same benefits as it
                         makes generally available from time to time to the
                         Company's employees, as those benefits are amended or
                         terminated from time to time. Your participation in the
                         Company's benefit plans

                                                                   Page 2 of 24
<PAGE>

                         will be subject to the terms of the applicable plan
                         documents and the Company's generally applied policies,
                         and the Company in its sole discretion may from time to
                         time adopt, modify, interpret, or discontinue such
                         plans or policies. It is the Company's good faith
                         intention to provide information on additional
                         executive benefits, if any, within 90 days of the
                         execution of this agreement.

Place of Employment      Your principal place of employment will be within 50
                         miles of Fort Washington, Pennsylvania.

Expenses                 The Company will reimburse you for reasonable and
                         necessary travel and other business-related expenses
                         you incur for the Company in performing your duties
                         under this Agreement. You must itemize and substantiate
                         all requests for reimbursements. You must submit
                         requests for reimbursement in accordance with the
                         policies and practices of the Company.

No Other Employment      While the Company employs you, you agree that you will
                         not, directly or indirectly, provide services to any
                         person or organization for which you receive
                         compensation or otherwise engage in activities that
                         would conflict or interfere significantly with your
                         faithful performance of your duties as an employee
                         without the Board's prior written consent. (This
                         prohibition excludes any work performed at the
                         Company's direction.) You may manage your personal
                         investments, as long as the management takes only
                         minimal amounts of time and is consistent with the
                         provisions of the No Conflicts of Interest Section and
                         the No Competition Section in Exhibit A.

                         You represent to the Company that you are not subject
                         to any agreement, commitment, or policy of any third
                         party that would prevent you from entering into or
                         performing your duties under this Agreement, and you
                         agree that you will not enter into any agreement or
                         commitment or agree to any policy that would prevent or
                         hinder your performance of duties and obligations under
                         this Agreement, including Exhibit A.

                                                                   Page 3 of 24

No Conflicts of Interest You confirm that you have fully disclosed to the
                         Company, to the best of your knowledge, all
                         circumstances under which you, your spouse, and other
                         persons who reside in your household have or may have a
                         conflict of interest with the Company. You further
                         agree to fully disclose to the Company any such
                         circumstances that might arise during your employment
                         upon your becoming aware of such circumstances. You
                         agree to fully comply with the Company's policy and
                         practices relating to conflicts of interest.

No Improper              You will neither pay nor permit payment of any
                         remuneration to or

Payments                 on behalf of any governmental official other than
                         payments required or permitted by applicable law. You
                         will comply fully with the Foreign Corrupt Practices
                         Act of 1977, as amended. You will not, directly or
                         indirectly,

                              make or permit any contribution, gift, bribe,
                              rebate, payoff, influence payment, kickback, or
                              other payment to any person or entity, private or
                              public, regardless of what form, whether in money,
                              property, or services

                                   to obtain favorable treatment for business
                                   secured,

                                   to pay for favorable treatment for business
                                   secured,

                                   to obtain special concessions or for special
                                   concessions already obtained, or

                                   in violation of any legal requirement, or

                              establish or maintain any fund or asset related to
                              the Company that is not recorded in the Company's
                              books and records, or

                              take any action that would violate (or would be
                              part of a series of actions that would violate)
                              any U.S. law relating to international trade or
                              commerce, including those laws

                                                                   Page 4 of 24

                              relating to trading with the enemy, export
                              control, and boycotts of Israel or Israeli
                              products (as is sought by certain Arab countries).

Termination         Subject to the provisions of this section, you and the
                    Company agree that it may terminate your employment, or you
                    may resign, except that, if you voluntarily resign, you must
                    provide the Company with 90 days' prior written notice
                    (unless the Board or your Direct Report has previously
                    waived such notice in writing or authorized a shorter notice
                    period).

     For Cause      The Company may terminate your employment for "Cause" if
                    you:

                         (i)    commit a material breach of your obligations or
                         agreements under this Agreement, including Exhibit A;

                         (ii)   commit an act of gross negligence with respect
                         to the Company or otherwise act with willful disregard
                         for the Company's best interests, or materially violate
                         the Company's business practices and policies as set
                         forth in its Employee Handbook;

                         (iii)  fail or refuse to perform any duties delegated
                         to you that are reasonably consistent with the duties
                         of similarly-situated senior executives or are
                         otherwise required under this Agreement, provided that
                         these duties do not conflict with any other provision
                         of this Agreement;

                         (iv)   seize a corporate opportunity for yourself
                         instead of offering such opportunity to the Company if
                         within the scope of the Company's or its subsidiaries'
                         business; or

                         (v)    are convicted of or plead guilty or no contest
                         to a felony (or to a felony charge reduced to
                         misdemeanor), or, with respect to your employment,
                         commit either a

                                                                   Page 5 of 24
<PAGE>

                         material dishonest act or common law fraud or knowingly
                         violate any federal or state securities or tax laws.

                    Your termination for Cause will be effective immediately
                    upon the Company's mailing or written transmission of notice
                    of such termination.  Before terminating your employment for
                    Cause under clauses (i) - (iv) above, the Company will
                    specify in writing to you the nature of the act, omission,
                    refusal, or failure that it deems to constitute Cause and,
                    unless the Board or your Direct Report reasonably concludes
                    the situation could not be corrected, give you 30 days after
                    you receive such notice to correct the situation (and thus
                    avoid termination for Cause), unless the Company agrees to
                    extend the time for correction.  You agree that the Board or
                    your Direct Report will have the discretion to determine in
                    good faith whether your correction is sufficient, provided
                    that this decision does not foreclose you from using the
                    Dispute Resolution provisions of Exhibit B.

     Without Cause  Subject to the provisions below under Payments on
                    Termination and Severance, the Company may terminate your
                    employment under this Agreement before the end of the Term
                    without Cause.

     Disability     If you become "disabled" (as defined below), the Company may
                    terminate your employment. You are "disabled" if you are
                    unable, despite whatever reasonable accommodations the law
                    requires, to render services to the Company because of
                    mental disability, incapacity, or illness, for more than the
                    sum of:

                         a)   90 consecutive days,
                         b)   the number of earned but unused vacation days (see
                              the Vacation paragraph of this Agreement for the
                              number of vacation days available per year), and
                         c)   the number of earned but unused personal and sick
                              days generally available from time to time to the
                              Company's employees, as those benefits are amended
                              or terminated from time to time.

                                                                   Page 6 of 24
<PAGE>

                    You are also disabled if you are found to be disabled within
                    the meaning of the Company's long-term disability insurance
                    coverage as then in effect (or would be so found if you
                    applied for the coverage), and you have no remaining:

                         a)   earned but unused vacation days (see the Vacation
                              paragraph of this Agreement for the number of
                              vacation days available per year), and
                         b)   earned but unused personal and sick days generally
                              available from time to time to the Company's
                              employees, as those benefits are amended or
                              terminated from time to time.

     Good Reason    You may resign for Good Reason with 45 days' advance written
                    notice. "Good Reason" for this purposes means, without your
                    consent, (i) the Company materially breaches this Agreement
                    or (ii) the Company relocates your primary office by more
                    than 50 miles from Fort Washington, Pennsylvania.

                    You must give notice to the Company of your intention to
                    resign for Good Reason within 30 days after the occurrence
                    of the event that you assert entitles you to resign for Good
                    Reason.  In that notice, you must state the condition that
                    you consider provides you with Good Reason and, if such
                    reason relates to clause (i) above, must give the Company an
                    opportunity to cure the condition within 30 days after your
                    notice.  Before or during the 30 day period, either party
                    may request mediation under Exhibit B to resolve any such
                    disputes, and, if so requested, the parties agree to
                    cooperate to arrange a prompt mediation during no more than
                    a 30 day period.  If the Company fails to cure the
                    condition, your resignation will be effective on the 45th
                    day after your notice (unless the Board has previously
                    waived such notice period in writing or agreed to a shorter
                    notice period or unless mediation is proceeding in good
                    faith), in which case such resignation will become effective
                    15 days after the end of such mediation, if not previously
                    cured.

                                                                   Page 7 of 24

                    You will not be treated as resigning for Good Reason if the
                    Company already had given notice of termination for Cause as
                    of the date of your notice of resignation.

                    In addition, you will not be treated as resigning for Good
                    Reason if the Company changes your position as Senior Vice
                    President, Client Services, to another Senior Vice President
                    position suitable for your skills, provided that the terms
                    of such position do not violate any other provisions of this
                    Agreement.

     Death          If you die during the Term, the Term will end as of the date
                    of your death.

     Payments on    If you resign or the Company terminates your employment with
     Termination    or without Cause or because of disability or death, the
                    Company will pay you any unpaid portion of your Salary pro-
                    rated through the date of actual termination (and any annual
                    bonuses already determined by such date but not yet paid
                    unless your employment is terminated with Cause), reimburse
                    any substantiated but unreimbursed business expenses, pay
                    any accrued and unused vacation time (to the extent
                    consistent with the Company's policies), and provide such
                    other benefits as applicable laws or the terms of the
                    benefits require. Except to the extent the law requires
                    otherwise or as provided in the Severance paragraph or in
                    your option agreements, neither you nor your beneficiary or
                    estate will have any rights or claims under this Agreement
                    or otherwise to receive severance or any other compensation,
                    or to participate in any other plan, arrangement, or
                    benefit, after such termination or resignation.

     Severance      In addition to the foregoing payments, if the Company
                    terminates your employment without Cause or you resign for
                    Good Reason, the Company will

                              pay you severance equal to your Salary, as then in
                              effect, for six months on the same schedule as
                              though you had remained employed during such
                              period, even though you are no longer employed;

                                                                   Page 8 of 24

                              pay the after-tax premium cost for you to receive
                              any group health coverage the Company must offer
                              you under Section 4980B of the Internal Revenue
                              Code of 1986 ("COBRA Coverage") for the period of
                              such coverage (unless the coverage is then
                              provided under a self-insured plan);

                              pay you, at the time the Company would otherwise
                              pay your annual bonus, your pro rata share of the
                              bonus for the year of your termination, where the
                              pro rata factor is based on days elapsed in your
                              year of termination till date of termination over
                              365, less any portion of the bonus for the year of
                              your termination already paid; and

                         It is the Company's good faith intention to provide
                         you, within 90 days of this agreement, a proposal of
                         the number of unvested options that will be subject to
                         accelerated vesting upon either termination without
                         cause, resignation for good reason, or as a result of a
                         change of control.  In the event you do not find such
                         proposal acceptable, you will be entitled to cancel
                         this agreement within 30 days of receipt of the
                         Company's proposal, provided such cancellation is
                         effected according to the Notices paragraph of this
                         Agreement.  In the event of such cancellation, the
                         provisions of your previous employment agreement, if
                         any, will be reinstated, and you will not be eligible
                         for any additional compensation or benefits offered
                         under this Agreement.

                         You are not required to mitigate amounts payable under
                         the Severance paragraph by seeking other employment or
                         otherwise, nor must you return to the Company amounts
                         earned under subsequent employment.

Change of Control        A Change of Control for this purpose means the
                         occurrence of any one or more of the following events:
                         a

                                                                   Page 9 of 24

                         person, entity, or group (other than the Company, any
                         Company subsidiary, any Company benefit plan, or any
                         underwriter temporarily holding securities for an
                         offering of such securities) acquires ownership of more
                         than 50% of the undiluted total voting power of the
                         Company's then-outstanding securities eligible to vote
                         to elect members of the Board ("COMPANY VOTING
                         SECURITIES"); consummation of a merger or consolidation
                         of the Company with or into any other entity -- unless
                         the holders of the Company Voting Securities
                         outstanding immediately before such consummation,
                         together with any trustee or other fiduciary holding
                         securities under a Company benefit plan, hold
                         securities that represent immediately after such merger
                         or consolidation at least 50% of the combined voting
                         power of the then outstanding voting securities of
                         either the Company or the other surviving entity or its
                         parent; or the stockholders of the Company approve (i)
                         a plan of complete liquidation or dissolution of the
                         Company or (ii) an agreement for the Company's sale or
                         disposition of all or substantially all the Company's
                         assets, AND such liquidation, dissolution, sale, or
                         disposition is consummated.


Expiration          Expiration of this Agreement, whether because of notice of
                    non-renewal or otherwise, does not constitute termination
                    without Cause nor provide you with Good Reason and does not
                    entitle you to Severance, unless the Company's general
                    severance practices entitle you to severance in that
                    situation.

                    This Agreement shall automatically renew for an additional
                    two year period unless, no less than 90 days before the end
                    of the Term, either party to this Agreement notifies the
                    other party, in accordance with the Notices paragraph, of
                    its intention to not renew the contract upon expiration of
                    the Term.

                                                                  Page 10 of 24
<PAGE>

                    If you remain employed at the end of the Term and your
                    employment then ends as a result of the Company's non-
                    renewal of this Agreement with substantially similar terms
                    to this Agreement, the Company will pay you severance equal
                    to your Salary, as then in effect, for 6 months on the same
                    schedule as though you had remained employed during such
                    period, even though you are no longer employed, which
                    payments you agree compensate you for the restrictions under
                    Exhibit A upon contract expiration.

Severability        If the final determination of an arbitrator or a court of
                    competent jurisdiction declares, after the expiration of the
                    time within which judicial review (if permitted) of such
                    determination may be perfected, that any term or provision
                    of this Agreement, including any provision of Exhibit A, is
                    invalid or unenforceable, the remaining terms and provisions
                    will be unimpaired, and the invalid or unenforceable term or
                    provision will be deemed replaced by a term or provision
                    that is valid and enforceable and that comes closest to
                    expressing the intention of the invalid or unenforceable
                    term or provision.

Amendment; Waiver   Neither you nor the Company may modify, amend, or waive the
                    terms of this Agreement other than by a written instrument
                    signed by you and an executive officer of the Company duly
                    authorized by the Board.  Either party's waiver of the other
                    party's compliance with any provision of this Agreement is
                    not a waiver of any other provision of this Agreement or of
                    any subsequent breach by such party of a provision of this
                    Agreement.

Withholding         The Company will reduce its compensatory payments to you for
                    withholding and FICA taxes and any other withholdings and
                    contributions required by law.


Governing Law       The laws of the State of Pennsylvania (other than its
                    conflict of laws provisions) govern this Agreement.

                                                                   Page 11 of 24

Notices             Notices must be given in writing by personal delivery, by
                    certified mail, return receipt requested, by telecopy, or by
                    overnight delivery. You should send or deliver your notices
                    to the Company's corporate headquarters.  The Company will
                    send or deliver any notice given to you at your address as
                    reflected on the Company's personnel records.  You and the
                    Company may change the address for notice by like notice to
                    the others.  You and the Company agree that notice is
                    received on the date it is personally delivered, the date it
                    is received by certified mail, the date of guaranteed
                    delivery by the overnight service, or the date the fax
                    machine confirms effective transmission.

Superseding Effect  This Agreement supersedes any prior oral or written
                    employment, severance, or fringe benefit agreements between
                    you and the Company, except with respect to:

                       a)   your eligibility for generally applicable employee
                            benefit plans

                       b)   any guaranteed, unpaid incentive pay or signing
                            bonus in accordance with your original offer latter
                            dated October 26, 2000, and

                       c)   other than with respect to any previously executed
                            option agreements between you and the Company.

                    This Agreement supersedes all prior or contemporaneous
                    negotiations, commitments, agreements, and writings with
                    respect to the subject matter of this Agreement, except as
                    noted in (a) through (c) above.  All such other
                    negotiations, commitments, agreements, and writings will
                    have no further force or effect; and the parties to any such
                    other negotiation, commitment, agreement, or writing will
                    have no further rights or obligations thereunder.

                         By:  /s/ R. Richard Dool



I accept and agree to the terms of employment set
forth in this Agreement:

/s/ Henry Hill

Dated: December 28, 2000

                                                                   Page 13 of 24

                                   Exhibit A
                                   ---------

No Competition      You agree to the provisions of this Exhibit A in
                    consideration of your employment by the Company and salary
                    and benefits under this Agreement and the training you will
                    receive in connection with such employment, and you agree
                    that Exhibit A should be considered ancillary to the option
                    agreements by which you will receive options from the
                    Company.  While the Company (or its successor or transferee)
                    employs you and to the end of the Restricted Period (as
                    defined below), you agree as follows:

                    You will not, directly or indirectly, be employed by, lend
                    money to, or engage in any Competing Business within the
                    Market Area (each as defined below).  That prohibition
                    includes, but is not limited to, acting, either singly or
                    jointly or as agent for, or as an employee of or consultant
                    to, any one or more persons, firms, entities, or
                    corporations directly or indirectly (as a director,
                    independent contractor, representative, consultant, member,
                    or otherwise) that constitutes such a Competing Business.
                    You also will not invest or hold equity or options in any
                    Competing Business, provided that you may own up to 3% of
                    the outstanding capital stock of any corporation that is
                    actively publicly traded without violating this No
                    Competition covenant, so long as you have no involvement
                    beyond passive investing in such business and you comply
                    with the second sentence of this paragraph.

                    If, during the Restricted Period, you are offered and want
                    to accept employment with a business that engages in
                    activities similar to the Company's, you will inform your
                    Direct Report in writing of the identity of the business,
                    your proposed duties with that business, and the proposed
                    starting date of that employment.  You will also inform that
                    business of the terms of this Exhibit A.  The Company will
                    analyze the proposed employment and make a good faith
                    determination as to whether it would threaten the Company's
                    legitimate competitive interests.  If the Company

                                                                   Page 14 of 24
<PAGE>

                    the Company Group  (including its predecessors) was used and
                    that was developed entirely on your own time, unless (a) the
                    invention relates (i) directly to the business of the
                    Company Group, or (ii) the Company Group's actual or then
                    reasonably anticipated research or development, or (b) the
                    invention results from any work you performed for the
                    Company Group or any predecessor.

Maximum Limits      If any of the provisions of Exhibit A are ever deemed to
                    exceed the time, geographic area, or activity limitations
                    the law permits, you and the Company agree to reduce the
                    limitations to the maximum permissible limitation, and you
                    and the Company authorize a court or arbitrator having
                    jurisdiction to reform the provisions to the maximum time,
                    geographic area, and activity limitations the law permits;
                    provided, however, that such reductions apply only with
                    respect to the operation of such provision in the particular
                    jurisdiction with respect to which such adjudication is
                    made.

Injunctive Relief   Without limiting the remedies available to the Company, you
                    acknowledge

                         that a breach of any of the covenants in this Exhibit A
                         may result in material irreparable injury to the
                         Company and  Company Group for which there is no
                         adequate remedy at law, and

                         that it will not be possible to measure damages for
                         such injuries precisely.

                    You agree that, if there is a breach or threatened breach,
                    the Company or any member of the Company Group may be
                    entitled to obtain a temporary restraining order and/or a
                    preliminary or permanent injunction restraining you from
                    engaging in activities prohibited by any provisions of this
                    Exhibit A or such other relief as may be required to
                    specifically enforce any of the covenants in this Exhibit A.
                    The Company or any member of the Company Group will, in
                    addition to the remedies provided in this

                                                                   Page 21 of 24

                    Agreement, be entitled to avail itself of all such other
                    remedies as may now or hereafter exist at law or in equity
                    for compensation and for the specific enforcement of the
                    covenants contained in this Agreement. Resort to any remedy
                    provided for in this Section or provided for by law will not
                    prevent the concurrent or subsequent employment of any other
                    appropriate remedy or remedies, or preclude the Company's or
                    the Company Group's recovery of monetary damages and
                    compensation. You also agree that the Restricted Period or
                    such longer period during which the covenants hereunder by
                    their terms survive will extend for any and all periods for
                    which a court with personal jurisdiction over you finds that
                    you violated the covenants contained in this Exhibit A.


                                   Exhibit B
                                   ---------
                               Dispute Resolution

Mediation      If either party has a dispute or claim relating to this Agreement
               or their relationship and except as set forth in Alternatives,
               the parties must first seek to mediate the same before an
               impartial mediator the parties mutually designate, and the
               parties must equally share the expenses of such proceeding (other
               than their respective attorneys' fees).  Subject to the
               mediator's schedule, the mediation must occur within 45 days of
               either party's written demand.  However, in an appropriate
               circumstance, a party may seek emergency equitable relief from a
               court of competent jurisdiction notwithstanding this obligation
               to mediate.

Binding        If the mediation reaches no solution or the parties agree to
Arbitration    forego mediation, the parties will promptly submit their
               disputes to binding arbitration before one or more arbitrators
               (collectively or singly, the "Arbitrator") the parties agree to
               select (or whom, absent agreement, a court of competent
               jurisdiction selects). The arbitration must follow applicable law
               related to arbitration proceedings and, where appropriate, the
               Commercial Arbitration Rules of the American Arbitration
               Association.

                                                                   Page 22 of 24

Arbitration    All statutes of limitations and substantive laws applicable to a
Principles     court proceeding will apply to this proceeding. The Arbitrator
               will have the power to grant relief in equity as well as at law,
               to issue subpoenas duces tecum, to question witnesses, to
               consider affidavits (provided there is a fair opportunity to
               rebut the affidavits), to require briefs and written summaries of
               the material evidence, and to relax the rules of evidence and
               procedure, provided that the Arbitrator must not admit evidence
               it does not consider reliable. The Arbitrator will not have the
               authority to add to, detract from, or modify any provision of
               this Agreement. The parties agree (and the Arbitrator must agree)
               that all proceedings and decisions of the Arbitrator will be
               maintained in confidence, to the extent legally permissible, and
               not be made public by any party or the Arbitrator without the
               prior written consent of all parties to the arbitration, except
               as the law may otherwise require.

Discovery;       The parties have selected arbitration to expedite the
Evidence;        resolution of disputes and to reduce the costs and burdens
Presumptions     associated with litigation. The parties agree that the
                 Arbitrator should take these concerns into account when
                 determining whether to authorize discovery and, if so, the
                 scope of permissible discovery and other hearing and pre-
                 hearing procedures. The Arbitrator may permit reasonable
                 discovery rights in preparation for the arbitration, provided
                 that it should accelerate the scheduling of and responses to
                 such discovery so as not to unreasonably delay the arbitration.
                 Exhibits must be marked and left with the Arbitrator until it
                 has rendered a decision. Either party may elect, at its
                 expense, to record the proceedings by audiotape or stenographic
                 recorder (but not by video). The Arbitrator may conclude that
                 the applicable law of any foreign jurisdiction would be
                 identical to that of Texas on the pertinent issue(s), absent a
                 party's providing the Arbitrator with relevant authorities (and
                 copying the opposing party) at least five business days before
                 the arbitration hearing.

Nature of Award  The Arbitrator must render its award, to the extent feasible,
                 within 30 days after the close of the hearing. The award must
                 set forth the material findings of fact and legal conclusions
                 supporting the award. The parties agree that it will be final,
                 binding, and enforceable by any court of competent
                 jurisdiction. Where necessary or appropriate to

                                                                   Page 23 of 24

               effectuate relief, the Arbitrator may issue equitable orders as
               part of or ancillary to the award. The Arbitrator must equitably
               allocate the costs and fees of the proceeding and may consider in
               doing so the relative fault of the parties. The Arbitrator may
               award reasonable attorneys' fees to the prevailing party to the
               extent a court could have made such an award.

Appeal         The parties may appeal the award based on the grounds allowed by
               statute, as well as upon the ground that the award misapplies the
               law to the facts, provided that such appeal is filed within the
               applicable time limits law allows.  If the award is appealed, the
               court may consider the ruling, evidence submitted during the
               arbitration, briefs, and arguments but must not try the case de
               novo.  The parties will bear the costs and fees associated with
               the appeal in accordance with the arbitration award or, in the
               event of a successful appeal, in accordance with the court's
               final judgment.

Alternatives   This Dispute Resolution provision does not preclude a party from
               seeking equitable relief from a court (i) to prevent imminent or
               irreparable injury or (ii) pending arbitration, to preserve the
               last peaceable status quo, nor does it preclude the parties from
               agreeing to a less expensive and faster means of dispute
               resolution.  It does not prevent the Company from immediately
               seeking in court an injunction or other remedy with respect to
               Exhibit A.
