Why Should I Read This Notice? The purpose of this Notice is to inform you that there is now pending in this Court a class action on behalf of certain California employers who purchased workers compensation insurance from Pacific Rim Assurance Company. On April 29, 1999, this Court gave preliminary approval to a settlement of the class action. The purpose of 1

this Notice is to describe the settlement to you. You should read this Notice to determine whether you wish to participate in the class action settlement. 2. What Is A Class Action? A class action is a type of lawsuit in which one or a few named plaintiffs bring suit on behalf of all of the members of a similarly situated group to recover damages for all of the group, without the necessity of each member filing an individual lawsuit or appearing as an individual plaintiff. Class actions are used by the courts where the claims raise basic issues of law or fact that are common, making it fair to bind all class members to the orders and the judgment in the case, without the necessity of hearing essentially the same claims over and over again. Use of a class action eliminates the necessity of filing multiple suits, and assures that all class members are bound by the results of the lawsuit. 3. What Is This Lawsuit About? On July 12, 1996, a lawsuit was filed in Los Angeles County Superior Court, case No. BC 153695, entitled California Sample Services, Inc. v. Pacific Rim Assurance Company. The lawsuit was brought by the Class Representative (California Sample Services, Inc.) on behalf of itself and on behalf of the Class defined below. The Class Representative is represented by Roxborough, Pomerance, Gallegos & Nye LLP and Shernoff, Bidart, Darras & Dillon ( The Plaintiff Class Counsel ). The Class Representative is an employer that purchased workers compensation insurance from Pacific Rim Assurance Company (herein, Pacific Rim ) from at least 1991 through 1995. The Class Representative alleges that Pacific Rim misreported medical-legal cost information for its individual injured workers claims to the California Workers Compensation Insurance Rating Bureau ( WCIRB ) from January 1, 1984 to December 31, 1992. The Class Representative was affected by such misreporting in the form of artificially inflated workers compensation premiums. Through the course of extensive investigation into the issue of medical-legal misreporting, the Plaintiff Class Counsel discovered that The Class Representative could not have been the only employer which suffered similar damages. As a result, The Class Representative alleges that they and other employers, whose premiums were calculated using the California Experience Rating System, ended up paying higher premiums for their workers compensation insurance. The Class Representative seeks relief based upon theories of breach of the implied covenant of good faith and fair dealing, negligence and unfair business practices under Business & Professions Code sections 17200, et seq. Following the filing of the lawsuit, the California Department of Insurance requested that the parties mediate their dispute, monitored by the Department of Insurance. Thereafter, the parties reached a settlement, endorsed by the Department of Insurance and preliminarily approved by this Court. On April 29, 1999, the Los Angeles Superior Court issued an order preliminarily certifying this case as a class action for settlement purposes and defining The Plaintiff Class as follows: All persons or business entities within the State of California which purchased workers compensation insurance policies from Pacific Rim incepting January 1, 1984 through December 31, 1992, and which, during that time, had at least one indemnity claim filed against it and an earned premium of no less than $5,000. On the same date, the Los Angeles Superior Court also approved the sending of this Notice to all California employers who purchased workers compensation insurance policies from Pacific Rim from January 1, 1984 through December 31, 1992, which, during that time, had at least one indemnity claim filed against them and an individual earned premium of no less than $5,000, to allow them the opportunity to indicate whether they want 2

to accept the benefits of the settlement more fully described below. The Court has set the date of August 23, 1999 to have a hearing on whether to finally approve the settlement. You are not required to appear at this hearing in order to accept the benefits of the settlement and you are not required to send in any further information to the Court regarding the settlement, unless you want to exclude yourself from the settlement, in which case you are required to take the actions more fully described in section 11. 4. What Is The Workers Compensation Insurance Rating Bureau? The Workers Compensation Insurance Rating Bureau of California ( WCIRB ) is a legislatively mandated organization that collects data about injured workers claims and employers payroll, and uses this data to develop workers compensation premium rates. The WCIRB requires that all employer workers compensation information be reported pursuant to its Unit Statistical Plan. Another important part of the WCIRB s duties is computing experience modifications ( EX-MODS ) for employers whose workers compensation insurance premiums are subject to experience rating. Experience rating applies to all qualifying employers over a certain size (corresponding to an annual premium of approximately $5,000). Under the WCIRB s Experience Rating Plan, each employer s claim losses, claim expenses, and payroll are reported by its insurance carrier to the WCIRB on an annual basis. The WCIRB then uses this data to calculate the employer s EX-MOD, using a formula set forth in the rating plan. The EX-MOD is a percentage figure that is used to adjust the employer s workers compensation premium, based on claims experience. Generally, the higher the losses reported, the higher the resulting premium. The Unit Statistical Plan in effect from 1983 through 1992 required that medical costs incurred in the defense of a workers compensation claim be reported in a particular manner. The manner in which such information was reported had a direct impact on the employer s EX-MOD, which in turn determined that employer s future premium rate. In 1995, a system of open competitive rating incepted in California. Workers compensation carriers set their own premium rates, approved by the California Department of Insurance. Workers compensation carriers must still report certain statistical information to the WCIRB. 5. Who Is Included In This Class Action? On April 29, 1999, the Court certified for settlement purposes a preliminary statewide Plaintiff Class under California Code of Civil Procedure section 382 and Chapter 15 of the Los Angeles Superior Court Rules. The Plaintiff Class is defined as set forth in Section 3 above. The class settlement excludes from participation all persons who, in accordance with the terms of this Notice, execute a timely request for exclusion from the settlement, and thus, voluntarily opt-out of this class action proceeding. 6. What Are The Terms Of The Settlement? The terms of the settlement in this case, preliminarily approved by the Court on April 29, 1999, are as follows: a. Pacific Rim shall make available to The Plaintiff Class benefits totaling $487,500 in the form of policy premium credits to be dispersed to The Plaintiff Class. The policy premium credits shall be freely transferrable between Pacific Rim and the following workers compensation carriers also subject to proposed settlement approval before the Los Angeles Superior Court: California Compensation Insurance Company (Los Angeles Superior Class Action Case No. 157151) (herein, Cal Comp ) and Superior National Insurance Company (Los Angeles Superior Class Action Case No. BC 159813) (herein, Superior National ). The policy premium credits may be used to reduce premium owed by The Plaintiff Class upon renewal of a Pacific Rim, Cal Comp or Superior National workers compensation policy or upon inception of a new such policy, subject to the applicable carrier s underwriting standards ( the Class Benefit ). b. The policy premium credits will be sent to each policyholder for each policy issued from January 1, 1984 3

through December 31, 1992. The policy premium credits will be available for use for a period of thirty-six (36) months from the date of issuance. The value of the policy premium credit will be calculated following notification to the Plaintiff Class and opportunity to opt-out of the proposed settlement. c. After expiration the total thirty-six (36) month redemption period, Pacific Rim shall calculate the value of any unredeemed policy premium credits issued, and shall issue additional policy premium credits from the residuary of the class settlement. The second policy premium credit will be valid for a fourteen (14) month period from the date of issuance. d. In addition to the Class Benefit, Pacific Rim and The Class Representative agreed The Plaintiff Class Counsel shall receive $250,000 in attorneys fees and reimbursable costs not to exceed $12,500 to reimburse the time and expenses incurred by The Plaintiff Class Counsel in connection with the litigation against Pacific Rim. In addition, this amount reflects the benefit The Plaintiff Class Counsel conferred upon The Plaintiff Class. e. The settlement is more fully described in the papers and pleadings on file with this Court which can be obtained as set forth below. The Court will decide whether to finally approve this settlement at the hearing for final approval on August 23, 1999. f. If you elect not to use your policy premium credit by renewal of a current workers compensation policy or procurement of a new workers compensation policy with Pacific Rim, Cal Comp or Superior National, then you will not receive the Class Benefit conferred by this settlement. Thus you may consider the opt-out procedures explained more fully in paragraphs 11 and 12. 7. Do I Need To Do Anything In Order To Participate In The Settlement? No. If you wish to remain a member of The Plaintiff Class, you do not need to do anything at this time. 8. What Information Will Be Needed Concerning My Business? None.
