Kaufman & Broad. Total 16,597 options The options being irrevocable, this number may not be modified during the term of the options, except in the case of an adjustment of the number of shares and of the purchase price made necessary by the completion of the financial operations referred to in paragraph 5 below. 3. CHARACTERISTICS OF THE OPTIONS The granting of the options constitutes an irrevocable undertaking on the part of the company in favor of the beneficiary. The options may be exercised by the beneficiary personally. The options and the rights resulting from the options granted are not assignable and not attachable. However, in the event of the death of a beneficiary, and in accordance with Article 208-7 of the Law on commercial companies, such beneficiary's assigns may exercise the option within six months of the death, as indicated below. The exercise of the option is optional for the beneficiary. 4. ESTABLISHMENT OF THE PURCHASE PRICE OF THE SHARES The purchase price of the shares by the beneficiaries at the time such options are exercised has been determined on the basis of the consolidated equity at November 30, 1996 (US GAAP standards), i.e., FF 279,739,000. The price per share obtained therefrom is FF 1,440.90 (FF 279,739,000 divided by 194,412 shares). The above-mentioned price was defined by the extraordinary general meeting of October 30, 1997 in light of the report issued by the statutory 9 -4- auditor. The price as determined shall be paid as indicated in paragraph II-2 below. 5. ADJUSTMENT OF THE PURCHASE PRICE In accordance with the law, the purchase price of the shares may not be modified during the term of the option, i.e., until the term of the plan. However, if during such period the company carries out certain financial transactions having an impact on the capital, the Board of Directors will adjust the price of the shares subject to not as yet exercised options, so that the total value of the current options of the beneficiaries remains constant. The terms and conditions for the calculation of these adjustments are defined by the law. The financial transactions referred to above are the following: - issuance of shares to be subscribed for in cash; - issuance of bonds giving a right to shares (bonds with warrants, convertible or exchangeable into shares); - capitalization of reserves, profits or issuance premiums; - distribution of reserves in cash or in portfolio shares; - reduction of the capital because of losses. 6. FUTURE AWARDS The 2,817 shares remaining to be awarded after the initial distribution (i.e., the difference between the 19,414 authorized shares and the 16,597 shares awarded under paragraph I-2 above) may be awarded in the coming years. These future awards will be made between March 1 and June 30 of each year - subject to modifications of the law or the regulations limiting the periods during which the options may be awarded - the exercise price being determined on the basis of the consolidated equity of Kaufman & Broad France (US GAAP standards) at the previous November 30.

TERMS AND CONDITIONS FOR THE EXERCISE OF THE OPTIONS The options may be exercised partially or totally. The exercise of the option shall be notified by its beneficiary (or in the case of death, by his assigns) by registered letter with return receipt requested sent to the company (or to the body instructed by the latter) in a form stipulated by the company with the assistance of the option exercise form attached hereto. This form will be completed, dated and signed when the option is exercised. The form will be accompanied by the payment by check of the amount of the purchase price of the shares. However, to enable the accomplishment of the financial transactions reserved to shareholders, the company may reserve the option of suspending the exercise of the stock options granted during a maximum of three months. In this case, the beneficiaries will be informed of the dates of the suspension and resumption of the exercise of the options by letter sent at least fifteen days in advance. If an option is exercised partially, the balance will remain exercisable according to the same conditions. III. CHARACTERISTICS OF THE SHARES ACQUIRED 1. FORM - ACQUISITION OF RIGHTS The shares will obligatorily be in registered form, thus fulfilling all the conditions required to be able to benefit from the favorable tax regime granted to stock options. The shares acquired will acquire their rights as from the first day of the fiscal year during which the options are exercised, the date of the option exercise form attesting thereto. They will be entitled to the whole amount of the dividend paid for such fiscal year. They will be subject to all the provisions of the by-laws. 14 -9- 2. AVAILABILITY OF THE SHARES The shares acquired will be immediately transferable. IV. TAX AND SOCIAL SECURITY REGIME 1. The benefit gained by the beneficiary at the time the option is exercised (difference between the value of the shares when the option is exercised and the purchase price, hereinafter referred to as the "capital gain on the acquisition") is not taxed immediately and will only be subject to taxation at the time of the sale of the shares by the beneficiary of the purchase option. At this time, the "capital gain on the sale" equal to the difference between the actual selling price and the value of the share on the date the option is exercised will be subject to the regime governing capital gains on securities. In the current state of the legislation and in accordance with the combined provisions of Articles 92-B and B bis of the French Tax Code (CGI), this capital gain will only be subject to income tax (at the proportional rate of 16% increased by the social deduction of 2%, the CSG at the current rate of 7.5% and the CRDS at the current rate of 0.5%, i.e., a total deduction of 26%), in the event that the amount of the sales made by the beneficiary of the option plan exceeds an annual ceiling (fixed at FF 100,000 for 1997). To assess this taxation threshold, all of the sales of shares, whether they are listed or unlisted (other than those of partnerships and companies in which the transferor holds more than 25% of the shares) made by the tax household during the year concerned must be taken into account. The "capital gain on the acquisition" which had not been taxed at the time the option was exercised is, subject to reaching the capital gains taxation threshold, taxed at the time of the sale of the shares at the rate of 30% (increased by the social deduction of 2%, the CSG at the current rate of 7.5% and the CRDS at the current rate of 0.5%, i.e., a total deduction of 40%), if, in accordance with the provisions of Article 163-bis C of the CGI, the two following conditions have been met: - the shares acquired upon exercise of the option remained in registered form, 15 -10- - the period between the award date of the options and the date of sale of the shares is more than five years. The beneficiary may also, in this case, opt to have the "capital gain on the acquisition" taxed for income tax for the year of the sale of the shares, in the category of wages and salaries (without applying the system of the quotient). If the beneficiary does not respect one of the two above-mentioned conditions, the "capital gain on the acquisition", reduced however, by the amount of any capital loss on the sale constitutes for the beneficiary an additional compensation to be added to his taxable salary of the year of the sale. However, adding back is carried out by a system of quotients which takes into account the number of years that have elapsed between the offering and the sale. As an exception to the rule of unavailability, the shares may be sold before the expiration of the five-year period fixed by Article 163-bis C of the CGI without losing the benefit of the favorable tax regime provided for in such article in the following four cases: - dismissal of the holder provided that such shares have been acquired at least three months prior to the notification of dismissal; - the holder's being asked to retire provided that such shares have been acquired at least three months prior to his stopping work; - the holder's invalidity corresponding to the classification in the 2nd or 3rd category provided for in Article L 341-1 of the Social Security Code; - death of the holder. OBLIGATIONS OF THE COMPANY - For the year in which the option is exercised, the company will be required to deliver to the beneficiary, no later than February 15 of the following year, an individual statement mentioning its corporate name, the place of its principal place of business and the place of its registered office, if different, the dates of the award and exercise of 16 -11- the options, the number of shares acquired and their unit purchase price. Moreover, the company will send within the same period (no later than February 15) a duplicate of such statement to the local tax authorities on which it depends. - For the year in which the shares are sold, if this occurs prior to the end of the period of unavailability, the company must send, no later than February 15 of the following year, to the beneficiary and to the local tax authorities of the beneficiary's domicile, an individual statement mentioning the date of the sale (or the conversion into bearer shares) of the shares and the dates of the award and exercise of the option, the number of shares concerned, their purchase price and their value on the date on which the option is exercised. In the event of an exchange without a cash distribution (soulte) resulting from a public offering, merger, split-off, division or regrouping of shares carried out in accordance with the applicable regulations, the declaration obligations referred to above will be transferred to the company whose shares have been delivered in exchange for those acquired under the option and will henceforth cover these new shares. OBLIGATIONS OF THE BENEFICIARY For the year in which the option is exercised, the beneficiary must send with his tax declaration the individual statement delivered to him by the company. For the year in which the shares are sold, the beneficiary is required to indicate on his tax declaration of the year of the sale on the one hand the difference between the value of the shares on the date the option is exercised and their purchase price(1) and on the other hand the capital gain recorded on the date of the sale, equal to the difference between the sale price and the value of the shares on the date on which the option is exercised, if the conditions for taxation of this capital gain are met. The failure, both by the company and the beneficiary, to respect the declaration obligations mentioned above shall result in the forfeiture of the favorable tax regime of Article 163 bis C of the CGI and the taxation under - -------- (1) This capital gains being taxable either in the category of wages and salaries (sale before the expiration of the period of unavailability) or at the current rate of 40% (sale after the expiration of the period of unavailability). 17 -12- ordinary law conditions of the benefit obtained at the time the option is exercised. Moreover the company, with regard to the obligations it has not respected, is liable for the fiscal fines provided for in Articles 1725 and 1726 of the CGI. 2. THE SOCIAL SECURITY REGIME APPLICABLE TO THE BENEFIT OBTAINED FROM THE EXERCISE OF THE OPTION IS THE FOLLOWING: The benefit obtained from exercising the option (i.e., the difference between the value of the share on the date the option is exercised and the option price) is exempt from social security contributions, with the exception of the part of the discount exceeding 5% of the price of the share at the time the option is granted. However, pursuant to Article L 242-1 paragraph 2 of the Social Security Code, social security contributions are due in the event that the holder of the option sells the shares subscribed for or acquired pursuant to his right insofar as the conditions provided for in Article 163 bis C-I of the CGI are not met, i.e., in particular before the expiration of a five-year period which started on the award date of the option. Such benefit will then be considered as additional salary and will be subject as such to social security contributions when the conditions of form and time provided for in Article 163 bis C-I referred to above are not satisfied, i.e., when the shares are not in registered form or when, except for a special event concerning the beneficiary (dismissal, being asked to retire, invalidity or death), they are sold before the expiration of a five-year period as from the date of the award of the option, the principle of being subject to such contributions being applicable to both the employer and the employee share of the contributions, and extending to deductions whose base is aligned on that of the social security contributions, it being specified that the benefit obtained from the exercise of the option will in these cases be subject to the CSG and the CRDS as salaries and no longer as income from assets.
