Guiding Principles Univar and Pakhoed wish to permit Pakhoed to evaluate (solely for purposes of the proposed transaction) environmental and product, toxic tort and similar liabilities related to Univar on the schedule set forth in the Protocol, while preserving the confidentiality of the proposed transaction and of the information collected during due diligence. Therefore, except as otherwise consented to by Univar, information shall be gathered only from the sources and in accordance with the procedures specified in this Due Diligence Approach and not from Univar facilities (other than its Kirkland headquarters) or through contacts with regulatory agencies. It is expected that some information will be needed from excluded sources, but Univar will make that information available only as agreed by the parties, for example by having Univar personnel or counsel obtain the information in a manner designed to protect confidentiality. Subject to the limitations in this Due Diligence Approach, the due diligence shall cover all known active and inactive Univar sites, in the US and elsewhere, including offsite locations where Univar may be a responsible/liable party. It has been estimated that this due diligence should take six weeks, but the Protocol requires that the due diligence be completed by May 24, 1996, which is expected to allow less than a month for due diligence. Therefore, both parties will make appropriate personnel and resources available on a priority basis to accomplish the due diligence by May 24, 1996. The due diligence will be conducted in a cooperative fashion designed to limit to the extent possible the need to obtain information from excluded sources while providing as much information as possible, keeping in mind the practical limitations imposed by the time available and the need for confidentiality. B. Personnel Graham and James ("G&J") will retain Harding Lawson Associates ("HLA"). Pakhoed's due diligence will be conducted by representatives of Pakhoed, HLA and G&J (the "Pakhoed team"). While Pakhoed retains the right to designate its team, it is expected that those representatives will for most purposes include: Rino Wong (Pakhoed); Vic Johnson ("VJ"), Larry Floyd ("LF") and Jim Briedlow ("JB") (HLA); and Maureen Bennett and either Andy Port or A-1 7 Rupert Hansen (G&J). Others who may be involved on a less frequent basis include Sjoerd Eikelboom, Roy Wansik and Jean Warren (Pakhoed) and Nick Unkovic (G&J). The Pakhoed team will have its primary contacts with Wayne Grotheer ("WG") and Joel Summer ("JS") (Univar) and Scott Vokey ("SRV") of Preston Gates & Ellis ("PG&E"), but may also have contacts with Jim Wiborg, Paul Hough, Gary Pruitt, Bill Butler and Rick Dodd (PG&E). C. Information Sources Univar will make available in an offsite data room at a site to be designated by Pakhoed: 1) all relevant and reasonably accessible information located in Univar's Kirkland headquarters or headquarters storage or under PG&E's control, 2) Univar's FY 1997 capital budget, 3) to the extent reasonably available, existing lists of known active and inactive Univar sites, including third party sites where Univar may be a responsible/liable party, and 4) on a priority basis, the assistance of the Univar personnel and representatives described above. The Pakhoed team will also have access to information: 1) contained in the files of Pakhoed, G&J and HLA (provided that HLA personnel other than VJ, LF and JB who have worked for Univar may not be informed of this project or that such information is being used), 2) available from commercially available data bases such as commercial electronic due diligence services (such as EDR) and from commercial serial photograph services, city directory services and historical mapping services (such as Sanborn), 3) available from other sources with prior permission of Univar, and 4) derived from discussions with the Univar personnel and representatives described above. Except as described above, the Pakhoed team will not, with respect to Univar and without prior permission from Univar A-2 8 1) contact any present or former Univar officers, directors, employees, attorneys, consultants, agents or other advisors, including without limitation present or former project managers, 2) contact any regulatory agency or its present or former personnel, contractors, consultants, attorneys or advisors, or review or request copies of any regulatory agency file, 3) visit, or request from any third person information concerning, (a) any present or former Univar leased or owned site or (b) any third party site at which Univar is or may be a potentially responsible/liable party, or 4) review (a) the files of project managers or (b) files located at Univar facilities. It is nevertheless expected that, with respect to a limited number of sites or pending or threatened litigation, information will be required from one or more of the above excluded sources. It is also expected that information that cannot now reasonably be anticipated will be required. The Pakhoed team will limit requests for such information to the extent possible, and Univar will cooperate to obtain such information in a manner agreeable to both Univar and Pakhoed. With respect to regulatory agency contacts, due to the difficulty in scheduling appointments with such agencies, the parties will use their best efforts to identify and pursue any such required contacts as early as possible in the process. D. Due Diligence Process and Schedule The due diligence process will commence upon execution of this agreement and agreement on the minimum acceptable tender offer price per Section 2.3 of the Protocol, extending the Pakhoed standstill period to two years. These conditions are expected to be fulfilled on April 26, 1996. Univar will make the information it is to provide (described above) available in the data room on April 29, 1996. The due diligence will commence that day with interviews of WG, JS and SRV, and will be completed no later than May 24, 1996. The parties will make available the personnel and resources necessary to accomplish this schedule. E. Uses of Due Diligence Information Neither Pakhoed, G&J, nor HLA will use any information developed during the due diligence for any purpose other than evaluation of the potential transaction, including but not limited to any attempt to require Univar to set environmental reserves, change any accounting policy, force Univar to make any disclosure, or in connection with any Univar project. Univar will not be required to develop any new cost estimates, and Pakhoed, G&J and HLA will keep confidential and not disclose to Univar or to any third parties any cost estimates or A-3 9 other information that Pakhoed, G&J or HLA may develop, in the course of the due diligence investigation. Pakhoed, HLA and G&J shall destroy all information developed pursuant to this due diligence protocol, including without limitation notes, schedules, and reports, if the potential transaction does not close in accordance with the Confidentiality and Standstill Agreement dated April 12, 1996.
