connection with the Licensed Rights shall be marketed and provided in accordance
with all applicable laws. HSA shall fully comply with the marking provisions of

the express Licensed Rights granted herein, Holdco is the sole and exclusive
owner of all right, title and interest in, to or in connection with the Software

                              TERM AND TERMINATION

         7.1 Term. This Agreement shall be of no force or effect until the

                  (a) HSA attempts to use, sublicense, subcontract, assign or
convey any rights granted herein in any manner contrary to the terms of this
Agreement, or take any other action inconsistent with or in derogation of
Holdco's exclusive and proprietary rights in any of the intellectual property
subject to this Agreement;

any of the CMB Intellectual Property rights; or

                  (c) HSA commits a material breach of any term, covenant or
condition of this Agreement, unless said breach is cured to the reasonable
satisfaction of Holdco within ten (10) days after receipt by HSA of notice and a
description of the breach.

                  In addition, the Agreement shall immediately terminate if HSA
files a voluntary petition under the United States Bankruptcy Code or the
insolvency laws or any similar statute, law, rule or regulation of any country,
territory, province or state; or has an involuntary petition filed against it
under any such law, or a receiver appointed for its business, unless such
petition or appointment of a receiver is dismissed within thirty (30) days.

                  7.3 Consequences of Expiration or Termination. Upon expiration

                                  ARTICLE VIII
                                 CONFIDENTIALITY

         8.1 Confidential Information. Each party shall maintain in confidence
all Confidential Information disclosed to it by the other party in connection
with performing its obligations hereunder. The receiving party shall not
disclose or make available to any third party or use such Confidential
Information except for disclosure to such party's employees, vendors,
contractors, subsidiaries and representatives and use only to the extent
necessary to enable such party to exercise its rights hereunder or as otherwise


                                       5


expressly authorized by this Agreement. The receiving party will use at least
the same standard of care as it uses to protect its own most confidential
information, which in no event shall be less than reasonable care, and will take
reasonable steps to ensure that its employees, agents or consultants do not
disclose or make any unauthorized use of such Confidential Information. The
receiving party will promptly notify the disclosing party upon discovery of any
unauthorized use or disclosure of the Confidential Information of the disclosing
party. With respect to all information exchanged after the Closing and within a
reasonable time after disclosure, such information must be marked with an
appropriate proprietary legend or identified as proprietary in order to be
protected as Confidential Information hereunder unless the confidential nature
of the Confidential Information is otherwise readily apparent.

         8.2 Exceptions. The obligations of confidentiality contained in Section
8.1 will not apply to the extent that it can be established by the receiving
party that such Confidential Information:

                  (a) was already known to the receiving party, other than under
an obligation of confidentiality, at the time of disclosure by the disclosing
party; provided that this subparagraph (a) shall not apply to excuse HSA from
its obligation of confidentiality with respect to otherwise Confidential
Information included in the Licensed Rights;

                  (b) was generally available to the public or otherwise part of
the public domain at the time of its disclosure to the receiving party;

                  (c) became generally available to the public or otherwise part
of the public domain after its disclosure and other than through any act or
omission of the receiving party in breach of this Agreement;

                  (d) was disclosed to the receiving party, other than under an
obligation of confidentiality, by a third party who had no obligation to the
disclosing party not to disclose such information to others.

         8.3 No Derogation of Licensed Rights. Nothing herein or in any other
agreement between the parties shall prohibit HSA from using Confidential
Information of Holdco to the extent permitted by this Agreement or from
disclosing Confidential Information of Holdco to the extent reasonably necessary
in connection with the exercise of any of the Licensed Rights; provided that any
recipient of Confidential Information in such manner is bound by an obligation
of confidentiality with respect to such Confidential Information.

                                   ARTICLE IX
                             ASSIGNMENT AND TRANSFER

         9.1 Subject to the provisions of this Article IX, neither this
Agreement nor any of the rights, interests, obligations or privileges hereunder
(including, without limitation, the licenses granted by Holdco hereunder) may be
assigned, sold, transferred, shared or encumbered, by operation of law or
otherwise, by HSA without the prior written consent of Holdco (it being further
understood that, unless otherwise agreed in writing, no such assignment shall
release HSA from any of its obligations or liabilities hereunder). An assignment
or transfer requiring the prior written consent of Holdco shall be deemed to


                                       6


occur upon any merger of HSA with or into any third party, any sale or transfer
of twenty-five percent (25%) or more of any one class of stock, or any series of
mergers, sales or transfers totaling in the aggregate twenty-five percent (25%)
or more of any one class of stock, in HSA, except in the case of stock sales
among existing shareholders in connection with any of the foregoing. If Holdco
consents to any such assignment or transfer, Holdco agrees to engage in good
faith negotiations with respect to a reasonable transfer or license fee for its
requested consent to such assignment and/or renewal of the International
Software Tools License. Subject to the foregoing, this Agreement shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective successors and assigns.

         9.2 Upon expiration of the International Software Tools License or a
merger, acquisition or divestiture with or to a purchaser of substantially all
of the assets of the Retained International Business that is not a competitor of
Holdco or its Affiliates and if Holdco consents to a renewal of the license or
to the transaction, Holdco agrees to engage in good faith negotiations with
respect to a commercially reasonable license renewal or transfer fee for such
consent to renewal or transfer of the International Software Tools License,
provided that HSA shall not be required to pay license fees on enhancements it
may have created or derived from the International Intellectual Property Rights.

         9.3 Holdco shall not, directly or indirectly, sell, transfer, assign,
pledge, encumber, give, place in trust, or otherwise voluntarily or
involuntarily dispose of any or all of the Software Tools, other than to a
Person who agrees to be bound in writing by the terms of this Agreement (it
being understood that, unless otherwise agreed in writing, no such assignment
shall release Holdco from any of its obligations or liabilities hereunder).

         9.4 Any attempted assignment in violation of the provisions hereof
shall be void ab initio and the assignee shall obtain no rights by reason
thereof.

         9.5 Subject to the provisions of this Article X, this Agreement shall
be binding upon, inure to the benefit of and be enforceable by the parties and
their respective successors and permitted assigns.

                                    ARTICLE X
                                  MISCELLANEOUS

         10.1 Notices. All notices or other communications hereunder shall be in
