1. Software License Grant. Subject to the terms of this Agreement, Authoria
   ----------------------
   grants to Licensee a nonexclusive license ("License") to use the Software
   identified in any Software Schedule attached to this Agreement at the
   Designated Location(s) during the Term. Licensee may transfer the Software to
   other locations owned or controlled by Licensee by providing prompt written
   notice to Authoria specifying the change in the Designated Location(s). The
   License shall extend to affiliates of Licensee to the extent provided in the
   Software Schedule, so long (and only so long) as Licensee owns or controls,
   directly or indirectly, stock or other interest in the affiliate representing
   more than fifty percent (50%) of the aggregate stock or other interest
   entitled to vote on decisions reserved to a vote by owners of such stock or
   other interest. Licensee's use of the Software shall be limited to Licensee's
   internal business purposes only, and, unless otherwise provided in the
   Software Schedule, Licensee may not use the Software to process accounts or
   records or to generate output data for the direct benefit of, or for purposes
   of rendering services to, any other business entities or organizations. In no
   event may Licensee allow timesharing, rental or use of the Software in
   service bureau.

2. Certain Restrictions. Licensee understands that the Software is a proprietary
   --------------------
   product of Authoria that contains trade secrets and is protected by copyright
   law. Authoria shall have sole and exclusive ownership of all right, title,
   and interest in and to the Software and documentation, all copies thereof,
   and all modifications and enhancements thereto (including ownership of all
   copyrights and other intellectual property rights pertaining thereto),
   subject only to the right and license expressly granted to Licensee herein.
   This Agreement does not provide Licensee with title or ownership of the
   Software, but only a right of limited use. Licensee may not use, copy,
   modify, or distribute the Software (electronically or otherwise), or any
   copy, adaptation, transcription, or merged portion thereof, except as
   expressly authorized by Authoria, an applicable Software Schedule, or a
   separate written agreement signed by Authoria. Licensee shall ensure that the
   Software is not modified, translated, examined, tested, subjected to
   simulated input, reverse engineered or decompiled or disassembled by
   attempted recreation of source code in any manner, for any reason including
   but not limited determining the mechanism, algorithms, processes or
   characteristics of the Software, provided Licensee may examine or test the
   Software only for authorized maintenance and error correction. Licensee shall
   further ensure that no person with access to the Software otherwise attempts
   to obtain or derive the object or source code of the Software or create any
   derivative works based on the Software or any software product or other work
   based on the mechanism, algorithms, processes or characteristics of the
   Software. Licensee agrees to keep the source code, object code, generic code
   and content of the Software confidential and not to disclose such codes to
   any other person or entity or to allow any other person or entity to copy or
   view such codes. Licensee agrees that it will not cause or permit the use of
   the Software and related documentation, or the ideas or concepts contained
   therein, as the basis of the development of any computer software products.
   For purposes of this Agreement, it will be presumed that any works developed
   or created by Licensee which involve the development of computer software
   performing substantially similar functions to the licensed Software, and are
   reduced to practice within three (3) years following the date of termination
   or expiration of the License granted hereunder, are the result of the breach
   of this Section and/or Section 3, Confidentiality, unless Licensee is able to
   establish otherwise by clear and convincing evidence. Notwithstanding
   anything to the contrary contained herein, this presumption will not apply in
   the event that Licensee independently develops products performing similar
   functions to the Software, so long as Licensee can show by clear and
   convincing documentary evidence, that (i) such products are developed for the
   benefit of individual clients of Licensee as part of an overall business
   solution, and are not generally marketed for commercial resale, (ii) neither
   the Software, nor the ideas or concepts contained therein, are used as the
   basis for development of such products, and (iii) no employee(s) of Licensee
   having access to the Software are involved, directly, or indirectly, in the
   development or design of such products. Licensee authorizes Authoria upon
   three (3) days' prior written notice to enter Licensee's premises in order to
   inspect the Software during regular business hours to verify compliance with
   the terms of this Agreement, provided that Licensee agrees not to conceal or
   destroy any software, materials or information after receiving such notice,
   through the completion of such inspection.

   ---------------
   which is identified as confidential and which is provided by one party to the
   other shall be considered "Confidential Information" under this Agreement.
   Each party shall take such measures to protect Confidential Information of
   the other party as it takes to protect its own similar proprietary and
   confidential information. This restriction shall not apply to any
   Confidential Information which is already known by the receiving party, is or
   becomes publicly available through no fault of the receiving party, or is
   required to be disclosed by government or judicial order. The terms of this
   Agreement shall be considered Confidential Information, and shall not be
   disclosed by either party without the prior written consent of the other. All
   Confidential Information provided to a party under this Agreement shall be
   returned to the disclosing party or destroyed promptly upon termination of
   this Agreement.

4. Authoria Services.  Subject to the terms of this Agreement, Authoria will
   -----------------
   provide Licensee with such Services as are described in any Services Schedule
   attached to this Agreement. Authoria may also make maintenance services
   available to Licensee under a separate maintenance agreement. In the event
   that Licensee requests consulting services that are beyond the scope of this
   Agreement and the maintenance agreement, Authoria may provide such services
   at is standard rates then in effect or recommend appropriate outside
   consultants. Any and all enhancements, modifications and corrections to the
   Software provided as part of any Authoria service will be considered part of

        data loss and/or a defect or malfunction that renders the Software or
        the computer systems on which they run nonoperational.

   Authoria reserves the right to charge additional service fees if an operator
seeks assistance with respect to such basic information or any other matters not
directly relating to the operation of the Software. Authoria does not hold
itself out as a professional expert and adviser regarding Licensee's computer or
information needs. Authoria is not responsible for obsolescence of the Software
that may result from changes in Licensee's requirements.

   to 1.5% per month (or, if less, the maximum rate allowable by law) on any
   balance remaining unpaid for more than thirty (30) days.

9. Limited Warranty.
   ----------------
   (a)  Authoria warrants that the Software shall not develop any faults due to
        the manipulation of data by the Software with dates prior to, through
        and including January 1, 2000. Notwithstanding the foregoing, Authoria
        makes no warranty whatsoever with respect to the Software's use or
        display of date related data, which may be read from third party
        systems.
   (b)  Authoria warrants that, prior to delivery of any media containing
        Software, it will take reasonable steps to test such media to ensure
        that the Software is free of programming devices (e.g., viruses, key

        Software or any system with which the Software operates, or destroy or
        damage data or make data inaccessible or delayed, except for file and
        purge routines necessary to the routine functioning of the Software.
   (c)  Authoria warrants that for a period of ninety (90) days following
        delivery, the Software will function substantially in accordance with
        the Specifications. Authoria does not warrant that the Software will be
        error free in all circumstances. As Licensee's exclusive remedy for any
        breach of this warranty, Authoria will, at its expense, replace or
        repair any Software that fails to meet this limited warranty. In the
        event that Authoria is unable to repair or replace the Software during
        the warranty period, Licensee may terminate its License and return the
        defective Software, and Authoria will provide Licensee with a refund of
        the License Fees paid for the Software in question. However, Authoria is
        not responsible for any defect or error not reported during the warranty
        period or any defect or error in Software that Licensee has modified,
        misused, or damaged.

   (d)  EXCEPT AS EXPRESSLY SET FORTH IN THIS SECTION, AUTHORIA MAKES NO
        WARRANTIES, EXPRESS, IMPLIED, STATUTORY, OR IN ANY OTHER PROVISION OF
        THIS AGREEMENT OR ANY OTHER COMMUNICATION. AUTHORIA SPECIFICALLY
        DISCLAIMS ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
        PURPOSE.

10. Limitation of Liability.  THE CUMULATIVE LIABILITY OF AUTHORIA TO LICENSEE
    -----------------------
    FOR ALL CLAIMS ARISING UNDER OR RELATED TO THIS AGREEMENT, WHETHER IN
    CONTRACT, TORT OR OTHERWISE, SHALL NOT EXCEED THE TOTAL AMOUNT OF ALL

    PARAGRAPH 11. IN NO EVENT WILL AUTHORIA OR ITS SUPPLIERS BE LIABLE TO
    LICENSEE FOR DAMAGES FOR LOSS OF DATA, LOST PROFITS, OR ANY INDIRECT,
    SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THIS AGREEMENT,
    EVEN IF AUTHORIA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR
    ANY CLAIM BY ANY THIRD PARTY. THE FOREGOING LIMITATION OF LIABILITY AND

    defend Licensee against such claim at Authoria's expense and pay all damages
    that a court finally awards, provided that Licensee promptly notifies
    Authoria in writing of the claim, allows Authoria to control, and cooperates
    with Authoria in, the defense or settlement of such action. If such a claim
    is made or appears possible, Authoria may, at its option, secure for
    Licensee the right to continue to use the Software, modify or replace the
    Software so they are noninfringing, or, if neither of the foregoing options
    is available in Authoria's judgment, require Licensee to return the Software
    for a credit equal to the portion of previously paid License fees allocable
    to the remaining term of the License. (If the License is perpetual, the
    License Fee will be amortized over a five-year useful life.) However,
    Authoria has no obligation for any claim based on a modified version of the
    Software or their combination, operation, or use with any product, data, or
    apparatus not provided by Authoria. THIS PARAGRAPH STATES AUTHORIA'S ENTIRE
    OBLIGATION TO LICENSEE WITH RESPECT TO ANY CLAIM OF INFRINGEMENT.

    any other agreement with Authoria, Authoria may, at its option, in addition
    to other available remedies, terminate the Software License granted under
    this Agreement and/or disable the Software, provided that it first gives
    Licensee fifteen (15) days' prior notice in order to permit Licensee to cure
    its default. Upon expiration or termination of any License, Licensee will
    promptly return or certify the destruction of all copies of the Software and
    all other materials pertaining to the Software, which are in Licensee's
    possession.

14. General.
    -------
    (a)  This Agreement, including any Schedule(s) attached hereto which have
         been signed by both parties, is the complete and exclusive statement of
         the agreement between the parties and supersedes all proposals or prior
         agreements, oral or written, and all other communications between the
         parties relating to the subject matter hereof. Any waiver or
         modification of the provisions of this Agreement will be effective only
         if in writing and signed by the party against whom it is to be
         enforced. In the event of a conflict with the provisions of any other
         document, the provisions of this Agreement will control.

    (b)  Persons and entities who have licensed software to Authoria for
         inclusion in the Software are third party beneficiaries to this
         Agreement as it applies to their respective software products included
         in the Software.
    (c)  Except for actions for nonpayment or breach of Authoria's proprietary
         rights in the Software, a delay or failure by either party to exercise
         any right or bring any action, within one (1) year of the event giving
         rise to such right or such cause of action, shall waive any and all
         rights relating to that action.
    (d)  All notices or other communications required to be given hereunder
         shall be in writing and delivered either personally or by U.S. mail,
         certified, return receipt requested, postage prepaid, and addressed as
         provided in this Agreement or as otherwise requested by the receiving
         party. Notices delivered personally shall be effective upon delivery
         and notices delivered by mail shall be effective upon their receipt by
         the party to whom they are addressed.
    (e)  This Agreement and the associated License may not be assigned by
         Licensee without Authoria's written consent, which shall not be
         unreasonably withheld. Licensee agrees that it shall not be considered
         unreasonable for Authoria to withhold Authoria's consent to an
         assignment to a party that is, or is likely to become, in Authoria's
         reasonable opinion, a competitor of Authoria.
    (f)  Licensee will be responsible for compliance with all legal requirements
         related to its use of the Software, including those related to the
         disclosure of data, and to any exports of Software made by Licensee.
    (g)  This Agreement shall be considered an agreement made in Massachusetts
         and shall be governed by and construed in accordance with the laws of
         the Commonwealth of Massachusetts.
