ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         As of the date hereof, (i) Whittier Ventures has invested $1 million in
49,519 shares of Chaparral's Common Stock, (ii) Whittier Energy has invested
$250,000 in 5,820 shares of Chaparral's Common Stock, (iii) Whittier Opportunity
has invested $10,000 in 158 shares of Chaparral's Common Stock, (iv) James A.

David A. Dahl has invested $10,000 in 167 shares of Chaparral's Common Stock,
all as described in Item 5 below. The source of these funds was the working
capital or personal funds of each of Whittier Ventures, Whittier Energy,
Whittier Opportunity, James A. Jeffs and David A. Dahl, as the case may be.

         On July 2, 1998, Whittier Ventures was granted warrants to purchase 334
shares of Chaparral's common stock at an exercise price of $0.60 per share. On
July 24, 1998, James A. Jeffs transferred to Whittier Opportunity options to
purchase 4,167 shares of Chaparral's common stock at an exercise price of $45
per share and 4,167 shares at an exercise price of $90 per share. On June 17,

Chaparral's outstanding 8.0% Non-Negotiable Convertible Subordinated Promissory
Notes (the "Notes") held by Whittier Ventures plus accrued interest owed on the
Notes into 2,255,004 shares of Chaparral's common stock at a conversion price of
$1.86 per share.

ITEM 4. PURPOSE OF TRANSACTION.

         With respect to the 2,255,004 shares of Chaparral's common stock
acquired by Whittier Ventures pursuant to the conversion of the Notes, Whittier
Ventures converted the Notes and accrued interest to facilitate Chaparral's
efforts to satisfy an equity infusion commitment to Shell Capital Limited
("Shell") under a $24.0 million loan agreement between Chaparral and Shell (the
"Loan"). In connection with the Loan, Chaparral committed to Shell to raise $6.0
million in equity or subordinated debt financing by June 30, 2000. Chaparral
failed to fulfill this obligation before June 30, 2000. Shell agreed to extend
the time deadline for Chaparral's commitment to raise the equity or debt
financing from June 30, 2000 to September 30, 2000, but increased the amount of
Chaparral's obligation from $6.0 million to $10.0 million. All other securities
reported herein were acquired for investment purposes.
