                            EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT ("Agreement") is hereby entered into between Triton
SystemHouse Pte. Ltd. ("Employer") and Mark R. Weaser ("Employee").

     WHEREAS, the Employer is presently engaged in a business that requires the
assistance of individuals with Employee's executive qualifications, skills and
experience, and

     WHEREAS, the Employer desires to procure the services of Employee and
Employee is willing to enter into the employ of the Employer upon the terms and
subject to the conditions set forth herein, and

     WHEREAS, the parties believe it is in their mutual interest to address in
this Agreement certain of their rights and responsibilities arising out of such
employment relationship, including matters pertaining to compensation,
ownership and protection of valuable confidential and proprietary information
of Employer, certain restrictions on business practices of Employee reasonably
needed to protect the Employer's legitimate business interests and other
important considerations addressed herein.

     NOW THEREFORE, for adequate consideration and intending to be legally
bound, the Employer hereby employs Employee, and the Employee hereby accepts
such employment with the Employer, upon the following terms and conditions:

1.   EMPLOYMENT POSITION.

     (a)  INITIAL DUTIES.  Employer hereby employs Employee to render services
to the Employer in the capacity of a General Manager and, in connection with
those services, Employee agrees to devote its full-time attention and efforts
to perform such duties and any incidental or further services as would normally
be expected of an employee working in Employee's capacity, as reasonably
determined by the Employer (see attached Job Description).

     (b)  CHANGES IN DUTIES.  Employee hereby accepts employment with
Employer in the capacity described in the attached Job Description referenced
in 1(a). Employer may from time to time change Employee's duties or re-assign
Employee to another position or location, according to Employer's business
needs.

     (c)  OUTSIDE BUSINESS ACTIVITIES.  As a full-time employee, the Employee
is expected to devote full-time attention and effort to the furtherance of
Employer's business interests and not to engage in any outside business
activities that would interfere with such work.  Employee shall provide
Employer advance written notice and full disclosure of any outside business
activity that Employee desires to pursue ("Outside Business") to permit
Employer to determine whether the Outside Business relates to the Employer's
own business or to the actual or demonstrably anticipated research or
development of Employer's business.  If approved by Employer, the Employee may
conduct such Outside Business, but entirely on Employee's own time and without
using any of Employer's equipment, supplies, facilities or Confidential or
Proprietary Information.  Employer shall maintain in confidence any trade
secrets disclosed by Employee with respect to an Outside Business approved by
Employer.  The Employee's pursuit of any Outside Business in no way waives or
otherwise relaxes the requirements of Section 4 ("Confidential & Proprietary
Information"), Section 5 ("Restrictions on Certain Business Practices") or
Section 8 ("No Conflicts").

2.   TERM.  The term of this Agreement ("Term") shall commence July 31, 1996

Employer may grant other employees in comparable positions and (ii) at the sole
discretion of the Employer in accordance with Subsection (c)("Compensation
Review").

     (b) INCENTIVE COMPENSATION.  Any incentive compensation payable to the
Employee beyond Base Compensation shall be determined from time to time by
Employer in its sole judgment.


                                                                             1

     (b) NONCOMPETITION.  In addition to other restrictions imposed by this
Agreement, Employee covenants and agrees during the period of employment and
for six (6) months thereafter, not to engage, directly or indirectly, whether

     (c) SEVERANCE. If Employer terminates Employee without cause, Employer
will pay total compensations for six (6) months after the termination date.

6.   REMEDIES.  Employee acknowledges and agrees that the Employer would be
irreparably harmed and that remedies at law would be inadequate to redress
the actual or threatened violations of Section 4 ("Confidential & Proprietary
Information") or Section 5 ("Restrictions on Certain Business Practices") and
that, in addition to other relief, the foregoing restrictions may be enforced
by temporary and permanent injunctive relief. The time periods referenced in
the foregoing restrictions shall be extended by any period in which Employee
is in breach thereof. The Employer's breach of any provision of this
Agreement shall not constitute a defense for any violation by Employee of the
foregoing restrictions. Remedies referenced in this Agreement shall be
considered cumulative and not exclusive.  Employee agrees to pay all costs
and expenses (including reasonable attorneys' fees) incurred by Employer in
enforcing the foregoing restrictions.

7.   MINIMUM REQUIREMENTS OF LAW.  The Employee acknowledges that the
provisions of Section 4 ("Confidential & Proprietary Information"), Section 5
("Restrictions on Certain Business Practices") and Section 6 ("Remedies") are
agreed to on the basis of adequate and substantial consideration, are
reasonably designed to protect legitimate and essential business interests
of Employer and that such provisions should be given full force and effect.
If, however, any such provision is found by a tribunal of competent
jurisdiction to be illegal or unenforceable in whole or in part then, to such
extent, the parties desire that the offending provision shall automatically
be deemed modified and conformed to the minimum requirements of law and
thereupon, together with all other provisions hereof (whether in their
original form or as modified hereunder), be given full force and effect.

8.   NO CONFLICTS.  Except to the extent made known to Employer by Employee
prior to the effective date hereof, Employee represents and warrants that (i)
it possesses the knowledge and skill reasonably required to render the
services contemplated hereunder in a professional and workmanlike manner,
(ii) it is not restricted by any other contract or other limitation of any
kind that would prevent or otherwise inhibit Employee from rendering the
services contemplated hereunder, (iii) in rendering the services hereunder,
Employee will not use any pre-existing work or divulge any information of any
previous employer or third party that would violate or infringe any patent,
copyright, trade secret or other proprietary rights of such employer or third
party and agrees at its own expense to defend, indemnify and hold Employer
harmless from any claim to the contrary, (iv) if the services contemplated
herein require Employee to obtain or maintain security or other background
clearance, then the employment contemplated herein is expressly conditioned
upon Employee's timely obtaining and maintaining such clearance during the
Term hereof, (v) Employee shall abide by Employer's generally applicable
rules and regulations from time to time in effect.

9.   TERMINATION.  Either party may terminate this Agreement if the other
party breaches any material provision hereof and fails within ten (10) days
after receipt of notice of default to correct such default or to commence
corrective action reasonably acceptable to the aggrieved party and proceed
with due diligence to completion. IN ADDITION, IT IS AGREED THAT THIS
RELATIONSHIP CONSTITUTES "EMPLOYMENT AT WILL" AND THAT EITHER PARTY MAY AT
ANY TIME TERMINATE THIS AGREEMENT WITH OR WITHOUT CAUSE UPON TWO (2) WEEKS'
ADVANCE WRITTEN NOTICE OR EQUIVALENT COMPENSATION IN LIEU OF SUCH NOTICE.
Termination of this Agreement, whether for cause, without cause, upon
expiration of the Term or otherwise, shall have no effect on the parties'
rights and obligations with respect to Section 4 ("Confidential & Proprietary
Information"), Section 5 ("Restrictions on Certain Business Practices") or
Section 8 ("No Conflicts").

10.  DISPUTES, CHOICE OF LAW.  Except for certain emergency judicial relief
authorized under Section 6 ("Remedies") which may be brought at any time, the
parties agree that all disputes between them shall first be subject to the
notice procedures in Section 9 ("Termination"), Employee shall initiate any
action to enforce this Agreement within one (1) year after the occurrence of
the alleged breach. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE SUBSTANTIVE LAWS OF THE REPUBLIC OF SINGAPORE AND ANY
ACTION OR OTHER PROCEEDING SHALL BE INITIATED AND MAINTAINED IN A FORUM OF
COMPETENT JURISDICTION IN SUCH COUNTRY.


                                                                             3
