                        COMPAQ SUPPLIER COMPLIANCE POLICY

COMPAQ COMPUTER CORPORATION IS PROUD OF ITS REPUTATION FOR INTEGRITY AND HONESTY
IN ITS BUSINESS DEALINGS. OUR CORPORATE CULTURE OF FAIRNESS AND QUALITY IS ONE
OF OUR MOST VALUABLE ASSETS. MAINTAINING THIS REPUTATION IS AN ONGOING PROCESS,
AND COMPAQ CONSIDERS IT TO BE ONE OF ITS MOST IMPORTANT JOBS.

IT IS ESSENTIAL THAT THE HIGHEST STANDARDS OF CONDUCT BE OBSERVED BY COMPAQ, AS
WELL AS ITS SUPPLIERS. IN FACT, COMPAQ BELIEVES THAT IT SUPPLIERS MUST OPERATE
AT THE SAME HIGH LEVEL OF INTEGRITY AS COMPAQ. IN THIS REGARD, COMPAQ HAS
ADOPTED A SUPPLIER COMPLIANCE POLICY. AS PART OF THIS POLICY, COMPAQ SUPPLIERS
MUST COMPLY FULLY WITH THE REQUIREMENTS SET FORTH BELOW. THIS POLICY REQUIRES
THAT COMPAQ SUPPLIERS AND THEIR EMPLOYEES EXERCISE THE HIGHEST DEGREE OF HONESTY
AND INTEGRITY IN CONDUCTING THEIR BUSINESS WITH COMPAQ, AS WELL AS OTHER THIRD
PARTIES.

I.       ETHICAL STANDARDS Compaq expects its suppliers to avoid conflicts of
         interest that create opportunities for abuses and allegations of
         commercial bribery.

         A. Conflicts of Interest - Suppliers are expected to avoid any action
         which may involve, or appears to involve, a conflict of interest with
         Compaq.

         B. Business Courtesies - Business should be won or lost on the merits
         of the products and services being offered by its suppliers. Therefore,
         supplier funds or personal funds of its employees should not be used to
         provide a business courtesy unless the gift is commemorative,
         ceremonial or customary in nature and has an insubstantial value. Under
         no circumstances should a kickback or bribe ever be offered to Compaq
         or its employees.

II.      ENVIRONMENTAL STANDARDS Compaq expects its suppliers to conduct their
         business in a manner that provides a safe, healthy and environmentally
         friendly workplace and meets or exceeds all applicable environment and
         work place legal requirements.

         A. Hazardous Materials, Air Emissions & Waste Water Discharges - Compaq
         requires that each of its suppliers comply with all applicable
         environmental laws and regulations regarding hazardous materials, air
         emissions and waste water discharges, including those regarding the
         manufacture, transportation, storage, disposal, and release to the
         environment of such materials.

         B. Health & Safety - Compaq expects its suppliers to maintain their
         facilities in a safe and healthy manner and in compliance with all
         applicable laws and regulations.

III.     EMPLOYMENT STANDARDS Compaq expects its suppliers to foster human
         dignity by treating their employees fairly and with respect. Compaq
         requires that its suppliers comply with all applicable national, state
         and local employment laws.

         A. Child Labor - Compaq expect its suppliers to refrain from using
         child labor. Workers can be no less than 14 years of age and not
         younger than the compulsory age to be in school. Compaq supports the
         development of legitimate workplace apprenticeship programs for the
         educational benefit of young people.

         B. Prison Labor - Compaq expects its suppliers to refrain from
         utilizing prison or forced labor within their work forces.

         C. Disciplinary Practices - Compaq expects its suppliers to refrain
         from using corporal punishment or other forms of mental or physical
         coercion with their employees.

         D. Working Hours - Compaq expects its suppliers to comply with all
         applicable laws regarding compensation for overtime work performed by
         their employees. Additionally, employees should be allowed at least one
         day off in seven.

IV.      COMPETITIVE STANDARDS Compaq expects its suppliers to compete fairly
         and vigorously within the marketplace. Compaq discourages
         anti-competitive practices by its suppliers that inhibit the operation
         of a free-market economy. Compaq requires that its suppliers comply
         with all applicable competition laws.

         A. Price fixing - Compaq expects its suppliers to refrain from
         collaborating with competitors to fix prices for its goods.

         B. Anticompetitive Practices - Compaq will not tolerate anticompetitive
         practices by its suppliers, including efforts to allocate markets or
         customers among their competitors or to fix bids.

V.       CONFIDENTIALITY Compaq requires that its suppliers enforce a policy
         that ensures the confidentiality of all proprietary or confidential
         information provided by Compaq.

         A. Non-disclosure Agreement - Compaq requires that its suppliers comply
         with the terms of the Confidentiality and Non-disclosure Agreements
         that have been entered into with Compaq

         B. Other Confidentiality Obligations - Compaq requires its suppliers to
         refrain from making unauthorized disclosures to Compaq of third party
         confidential information.

VI.      COMPLIANCE WITH GOVERNMENT LAWS AND REGULATIONS Compaq expects its
         suppliers to comply with all applicable laws and regulations governing
         their business relationships with Compaq. In addition, Compaq requires
         that its Suppliers agree to implement and maintain a Small,
         Woman-Owned, Minority Business Enterprise (SWMBE) program in accordance
         with Federal Acquisition Regulations (FAR) 52.219-0(d)(ll)(iii). Upon
         request by Compaq, Suppliers agree to provide Compaq with written
         certification of its compliance with the SWMBE Federal Acquisition
         Regulations.

COMPAQ IS DEDICATED TO MAINTAINING ITS REPUTATION FOR FAIRNESS AND INTEGRITY. IN
MANY WAYS THE FUTURE SUCCESS OF BOTH COMPAQ AND ITS SUPPLIERS DEPENDS ON OUR
ABILITY TO BUILD ON THESE HIGH STANDARDS.

THE FOREGOING REQUIREMENTS ARE NOT INTENDED TO BE ALL-INCLUSIVE, AND COMPAQ
EXPECTS ITS SUPPLIERS TO EXERCISE ETHICAL JUDGMENT BEYOND STRICT COMPLIANCE WITH
THE LAW, AND TO BE RESPONSIVE TO THE CONCERNS OF THE COMMUNITIES IN WHICH THEY
OPERATE. FAILURE TO COMPLY WITH THE ABOVE REQUIREMENTS MAY RESULT IN REDUCTION
OF BUSINESS WITH COMPAQ, OR IN SOME INSTANCES, TERMINATION OF YOUR RELATIONSHIP
WITH COMPAQ. UNDERSTANDING AND COMPLYING WITH THE ABOVE REQUIREMENTS WILL HELP
TO ENSURE THAT OUR MUTUAL BUSINESS ACTIVITIES ARE CONDUCTED IN THE HIGHEST
ETHICAL AND PROFESSIONAL MANNER.

     terms. Any Electronic Interchange properly transmitted pursuant to this
     Agreement shall be considered a "writing" or "in writing" and any such

                        COMPAQ SUPPLIER COMPLIANCE POLICY

COMPAQ COMPUTER CORPORATION IS PROUD OF ITS REPUTATION FOR INTEGRITY AND HONESTY
IN ITS BUSINESS DEALINGS. OUR CORPORATE CULTURE OF FAIRNESS AND QUALITY IS ONE
OF OUR MOST VALUABLE ASSETS. MAINTAINING THIS REPUTATION IS AN ONGOING PROCESS,
AND COMPAQ CONSIDERS IT TO BE ONE OF ITS MOST IMPORTANT JOBS.

IT IS ESSENTIAL THAT THE HIGHEST STANDARDS OF CONDUCT BE OBSERVED BY COMPAQ, AS
WELL AS ITS SUPPLIERS. IN FACT, COMPAQ BELIEVES THAT IT SUPPLIERS MUST OPERATE
AT THE SAME HIGH LEVEL OF INTEGRITY AS COMPAQ. IN THIS REGARD, COMPAQ HAS
ADOPTED A SUPPLIER COMPLIANCE POLICY. AS PART OF THIS POLICY, COMPAQ SUPPLIERS
MUST COMPLY FULLY WITH THE REQUIREMENTS SET FORTH BELOW. THIS POLICY REQUIRES
THAT COMPAQ SUPPLIERS AND THEIR EMPLOYEES EXERCISE THE HIGHEST DEGREE OF HONESTY
AND INTEGRITY IN CONDUCTING THEIR BUSINESS WITH COMPAQ, AS WELL AS OTHER THIRD
PARTIES.

I.       ETHICAL STANDARDS Compaq expects its suppliers to avoid conflicts of
         interest that create opportunities for abuses and allegations of
         commercial bribery.

         A. Conflicts of Interest - Suppliers are expected to avoid any action
         which may involve, or appears to involve, a conflict of interest with
         Compaq.

         B. Business Courtesies - Business should be won or lost on the merits
         of the products and services being offered by its suppliers. Therefore,
         supplier funds or personal funds of its employees should not be used to
         provide a business courtesy unless the gift is commemorative,
         ceremonial or customary in nature and has an insubstantial value. Under
         no circumstances should a kickback or bribe ever be offered to Compaq
         or its employees.

II.      ENVIRONMENTAL STANDARDS Compaq expects its suppliers to conduct their
         business in a manner that provides a safe, healthy and environmentally
         friendly workplace and meets or exceeds all applicable environment and
         work place legal requirements.

         A. Hazardous Materials, Air Emissions & Waste Water Discharges - Compaq
         requires that each of its suppliers comply with all applicable
         environmental laws and regulations regarding hazardous materials, air
         emissions and waste water discharges, including those regarding the
         manufacture, transportation, storage, disposal, and release to the
         environment of such materials.

         B. Health & Safety - Compaq expects its suppliers to maintain their
         facilities in a safe and healthy manner and in compliance with all
         applicable laws and regulations.

III.     EMPLOYMENT STANDARDS Compaq expects its suppliers to foster human
         dignity by treating their employees fairly and with respect. Compaq
         requires that its suppliers comply with all applicable national, state
         and local employment laws.

         A. Child Labor - Compaq expect its suppliers to refrain from using
         child labor. Workers can be no less than 14 years of age and not
         younger than the compulsory age to be in school. Compaq supports the
         development of legitimate workplace apprenticeship programs for the
         educational benefit of young people.

         B. Prison Labor - Compaq expects its suppliers to refrain from
         utilizing prison or forced labor within their work forces.

         C. Disciplinary Practices - Compaq expects its suppliers to refrain
         from using corporal punishment or other forms of mental or physical
         coercion with their employees.

                                                CONFIDENTIAL TREATMENT REQUESTED

         D. Working Hours - Compaq expects its suppliers to comply with all
         applicable laws regarding compensation for overtime work performed by
         their employees. Additionally, employees should be allowed at least one
         day off in seven.

IV.      COMPETITIVE STANDARDS Compaq expects its suppliers to compete fairly
         and vigorously within the marketplace. Compaq discourages
         anti-competitive practices by its suppliers that inhibit the operation
         of a free-market economy. Compaq requires that its suppliers comply
         with all applicable competition laws.

         A. Price fixing - Compaq expects its suppliers to refrain from
         collaborating with competitors to fix prices for its goods.

         B. Anticompetitive Practices - Compaq will not tolerate anticompetitive
         practices by its suppliers, including efforts to allocate markets or
         customers among their competitors or to fix bids.

V.       CONFIDENTIALITY Compaq requires that its suppliers enforce a policy
         that ensures the confidentiality of all proprietary or confidential
         information provided by Compaq.

         A. Non-disclosure Agreement - Compaq requires that its suppliers comply
         with the terms of the Confidentiality and Non-disclosure Agreements
         that have been entered into with Compaq

         B. Other Confidentiality Obligations - Compaq requires its suppliers to
         refrain from making unauthorized disclosures to Compaq of third party
         confidential information.

VI.      COMPLIANCE WITH GOVERNMENT LAWS AND REGULATIONS Compaq expects its
         suppliers to comply with all applicable laws and regulations governing
         their business relationships with Compaq. In addition, Compaq requires
         that its Suppliers agree to implement and maintain a Small,
         Woman-Owned, Minority Business Enterprise (SWMBE) program in accordance
         with Federal Acquisition Regulations (FAR) 52.219-0(d)(ll)(iii). Upon
         request by Compaq, Suppliers agree to provide Compaq with written
         certification of its compliance with the SWMBE Federal Acquisition
         Regulations.

COMPAQ IS DEDICATED TO MAINTAINING ITS REPUTATION FOR FAIRNESS AND INTEGRITY. IN
MANY WAYS THE FUTURE SUCCESS OF BOTH COMPAQ AND ITS SUPPLIERS DEPENDS ON OUR
ABILITY TO BUILD ON THESE HIGH STANDARDS.

THE FOREGOING REQUIREMENTS ARE NOT INTENDED TO BE ALL-INCLUSIVE, AND COMPAQ
EXPECTS ITS SUPPLIERS TO EXERCISE ETHICAL JUDGMENT BEYOND STRICT COMPLIANCE WITH
THE LAW, AND TO BE RESPONSIVE TO THE CONCERNS OF THE COMMUNITIES IN WHICH THEY
OPERATE. FAILURE TO COMPLY WITH THE ABOVE REQUIREMENTS MAY RESULT IN REDUCTION
OF BUSINESS WITH COMPAQ, OR IN SOME INSTANCES, TERMINATION OF YOUR RELATIONSHIP
WITH COMPAQ. UNDERSTANDING AND COMPLYING WITH THE ABOVE REQUIREMENTS WILL HELP
TO ENSURE THAT OUR MUTUAL BUSINESS ACTIVITIES ARE CONDUCTED IN THE HIGHEST
ETHICAL AND PROFESSIONAL MANNER.

6.   SECURITY PROCEDURES AND CONFIDENTIALITY OF USER IDS. (a) Each Party shall
