                           NONSTATUTORY STOCK OPTION

Roger Warren, Optionee:

         Bolder Technologies Corporation (the "Company") has granted to you,
the optionee named above, an option to purchase shares of the Common Stock of
the Company ("Common Stock"). This option is not intended to qualify and will
not be treated as an "incentive stock option" within the meaning of Section 422
of the Code.

         The details of your option are as follows:

         1. TOTAL NUMBER OF SHARES SUBJECT TO THIS OPTION. The total number of
shares of Common Stock subject to this option is twenty-two thousand (22,000).

         2. VESTING. Subject to the limitations contained herein, all of the
shares granted hereunder will vest (become exercisable) on September 30, 2006,
subject to acceleration upon achievement of performance objectives to be
established at the beginning of each year by the Company's Board of Directors,
unless and until you cease to provide services to the Company for any reason.

         3. EXERCISE PRICE AND METHOD OF PAYMENT.

                  (a) EXERCISE PRICE. The exercise price of this option is
$10.375 per share.

                  (b) METHOD OF PAYMENT. Payment of the exercise price per
share is due in full upon exercise of all or any part of each installment which
has accrued to you. You may elect, to the extent permitted by applicable
statutes and regulations, to make payment of the exercise price under one of
the following alternatives:

                           (i) Payment of the exercise price per share in cash
(including check) at the time of exercise; or

                           (ii) Payment pursuant to a program developed under
Regulation T as promulgated by the Federal Reserve Board which, prior to the
issuance of Common Stock, results in either the receipt of cash (or check) by
the Company or the receipt of irrevocable instructions to pay the aggregate
exercise price to the Company from the sales proceeds.

         4. WHOLE SHARES. This option may not be exercised for any number of
shares which would require the issuance of anything other than whole shares.

         5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, this option may not be exercised unless the shares issuable
upon exercise of this option are then registered under the Securities Act, or,
if such shares are not then so registered, the Company has determined that such
exercise and issuance would be exempt from the registration requirements of the
Securities Act.

         6. TERM. The term of this option commences on October 1, 1999, the
date of grant, and expires on September 30, 2009 (the "Expiration Date"),
unless this option expires sooner as

                                      1.

set forth below. In no event may this option be exercised on or after the
Expiration Date. Notwithstanding the foregoing, this option shall terminate
three (3) months after the termination of your Continuous Status as an
Employee, Director or Consultant for any reason and for no reason unless:

                  (a) such termination of Continuous Status as an Employee,
Director or Consultant is due to your disability (within the meaning of Section
422(c)(6) of the Code), in which event the option shall expire on the earlier
of the Expiration Date set forth above or twelve (12) months following such
termination of Continuous Status as an Employee, Director or Consultant; or

                  (b) such termination of Continuous Status as an Employee,
Director or Consultant is due to your death or your death occurs within three
(3) months following your termination for any other reason, in which event the
option shall expire on the earlier of the Expiration Date set forth above or
twelve (12) months after your death; or

                  (c) during any part of such three (3) month period the option
is not exercisable solely because of the condition set forth in paragraph 5
above, in which event the option shall not expire until the earlier of the
Expiration Date set forth above or until it shall have been exercisable for an
aggregate period of three (3) months after the termination of Continuous Status
as an Employee, Director or Consultant; or

                  (d) exercise of the option within three (3) months after
termination of your Continuous Status as an Employee, Director or Consultant
would result in liability under Section 16(b) of the Exchange Act, in which
case the option will expire on the earlier of (i) the Expiration Date set forth
above, (ii) the tenth (10th) day after the last date upon which exercise would
result in such liability or (iii) six (6) months and ten (10) days after the
termination of your Continuous Status as an Employee, Director or Consultant.

         However, this option may be exercised following termination of
Continuous Status as an Employee, Director or Consultant only as to that number
of shares as to which it was exercisable on the date of termination of
Continuous Status as an Employee, Director or Consultant under the provisions
of paragraph 2 of this option.

         7. EXERCISE.

                  (a) This option may be exercised, to the extent specified
above, by delivering a notice of exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require
pursuant to paragraph 7(b) below.

                  (b) The Company may require you, as a condition of exercising
this option: (i) to give written assurances satisfactory to the Company as to
your knowledge and experience in financial and business matters, and that you
are capable of evaluating the merits and risks of exercising this option; and
(ii) to give written assurances satisfactory to the Company that you are
acquiring the shares subject to the option for your own account and not with
any present


                                       2.
<PAGE>   3


intention of selling or otherwise distributing such shares. The foregoing
requirements, and any assurances given pursuant to such requirements, shall be
inoperative if (x) the issuance of the shares upon the exercise of this option
has been registered under a then currently effective registration statement
under the Securities Act, or (y) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued upon exercise of this option as such counsel deems
necessary or appropriate in order to comply with applicable securities laws,
including, but not limited to, legends restricting the transfer of the stock.

                  (c) By exercising this option, you agree that as a
precondition to the completion of any exercise of this option, the Company may
require you to enter an arrangement providing for the payment by you to the
Company of any tax withholding obligation of the Company arising by reason of:
(i) the exercise of this option; (ii) the lapse of any substantial risk of
forfeiture to which the shares are subject at the time of exercise; or (iii)
the disposition of shares acquired upon such exercise. You also agree that any
exercise of this option has not been completed and that the Company is under no
obligation to issue any Common Stock to you until such an arrangement is
established or the Company's tax withholding obligations are satisfied, as
determined by the Company.

         8. TRANSFERABILITY. This option is not transferable, except by will or
by the laws of descent and distribution or pursuant to a qualified domestic
relations order satisfying the requirements of Rule 16b-3 of the Exchange Act
(a "QDRO"), and is exercisable during your life only by you or a transferee
pursuant to a QDRO. Notwithstanding the foregoing, by delivering written notice
to the Company, in a form satisfactory to the Company, you may designate a
third party who, in the event of your death, shall thereafter be entitled to
exercise this option.

         9. ADJUSTMENTS UPON CHANGES IN STOCK.

                  (a) If any change is made in the shares subject to this
option without the receipt of consideration by the Company (through merger,
consolidation, reorganization, recapitalization, reincorporation, stock
dividend, dividend in property other than cash, stock split, liquidating
dividend, combination of shares, exchange of shares, change in corporate
structure or other transaction not involving the receipt of consideration by
the Company), the option will be appropriately adjusted in the class(es) and
number of shares and price per share of the stock subject thereto. Such
adjustments shall be made by the Board of Directors of the Company, the
determination of which shall be final, binding and conclusive. The conversion
of any convertible securities of the Company shall not be treated as a
"transaction not involving the receipt of consideration by the Company".

                  (b) In the event of: (i) a dissolution, liquidation or sale
of substantially all of the assets of the Company; (ii) a merger or
consolidation in which the Company is not the surviving corporation; or (iii) a
reverse merger in which the Company is the surviving corporation but the shares
of Common Stock of the Company outstanding immediately preceding the merger are
converted by virtue of the merger into other property, whether in the form of
securities, cash or otherwise, then to the extent permitted by applicable law:
(x) any surviving corporation or an Affiliate of such surviving corporation
shall


                                      3.
<PAGE>   4


assume this option or shall substitute a similar option therefor, or (y) this
option shall continue in full force and effect. In the event any surviving
corporation and its Affiliates refuse to assume or continue this option, or to
substitute a similar option therefor, then the time during which this option
may be exercised shall be accelerated and the option terminated if not
exercised prior to such event.

         10. OPTION NOT A SERVICE CONTRACT. This option is not an employment
contract and nothing in this option shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the
Company, or of the Company to continue your employment with the Company. In
addition, nothing in this option shall obligate the Company or any Affiliate,
or their respective stockholders, Boards of Directors, officers or employees to
continue any relationship which you might have as a Director or Consultant for
the Company or Affiliate.

         11. NOTICES. Any notices provided for in this option shall be given in
writing and shall be deemed effectively given upon receipt or, in the case of
notices delivered by the Company to you, five (5) days after deposit in the
United States mail, postage prepaid, addressed to you at the address specified
below or at such other address as you hereafter designate by written notice to
the Company.

         12. MISCELLANEOUS. The Board shall have the power to accelerate the
time at which this stock option may first be exercised or the time during which
this stock option or any part thereof will vest pursuant to section 2,
notwithstanding the provisions in this stock option stating the time at which
it may first be exercised or the time during which it will vest. Neither an
Employee, a Director, a Consultant nor any person to whom this stock option is
transferred in accordance with the terms hereof shall be deemed to be the
holder of, or to have any of the rights of a holder with respect to, any shares
subject to this stock option unless and until such person has satisfied all
requirements for exercise of this stock option pursuant to the terms hereof.
The Board of Directors at any time, and from time to time, may amend the terms
of this stock option; provided, however, that the rights and obligations under
this stock option shall not be impaired by any such amendment unless (i) the
Company requests the consent of the person to whom this stock option was
granted and (ii) such person consents in writing.

         13. DEFINITIONS.

                  (a) "AFFILIATE" means any parent corporation or subsidiary
corporation, whether now or hereafter existing, as those terms are defined in
Sections 424(e) and (f) respectively, of the Code.

                  (b) "CODE" means the Internal Revenue Code of 1986, as
amended.

                  (c) "CONSULTANT" means any person, including an advisor,
engaged by the Company or an Affiliate to render consulting services and who is
compensated for such services, provided that the term "Consultant" shall not
include Directors who are paid only directors' fee by the Company or who are
not compensated by the Company for their services as Directors.

                  (d) "CONTINUOUS STATUS AS AN EMPLOYEE, DIRECTOR OR
CONSULTANT" means the employment or relationship as a Director or Consultant is
not interrupted or terminated. The Board of Directors of the Company, in its
sole discretion, may determine whether Continuous


                                      4.

Status as an Employee, Director or Consultant shall be considered interrupted

as amended.

                  (h) "SECURITIES ACT" means the Securities Act of 1933, as
