                             MHL DEVELOPMENT COMPANY

                THIS AGREEMENT is made as of _____ ___, 2000 (the "Grant Date")
between mHL Development Company, an Oregon corporation (the "Company"), and
________________________ (the "Optionee").

        1. Option Grant. Pursuant to the Company's 1998 Stock Incentive Plan
(the "Plan"), a copy of which is attached as Exhibit A, the Company hereby
grants to the Optionee the right and option (the "Option") to purchase all or
any part of an aggregate of________ shares of the Company's authorized but
unissued or reacquired Common Stock at a purchase price of _______ per share.
The Option is a Non-Statutory Stock Option, as defined in the Plan. This
Agreement contains the entire understanding of, and supersedes any prior or
contemporaneous agreements between the Optionee and the Company regarding rights
to receive the Company's stock.

        2. Terms of Option. The Option is granted on the following terms and the
Optionee acknowledges that the following terms summarize certain provisions of
the Plan, and that the terms of the Plan, as interpreted by the Board of
Directors, will govern any matter described in the Plan:

                2.1 Duration of Option. The Option shall continue in effect for
a period of ten years from the Grant Date (the "Option Period").

                2.2 Right to Exercise. Subject to Section 2.3 of this Agreement,
the Option may be exercised from time to time in the following amounts: (a) none
before the first anniversary of the Grant Date; (b) one-fifth of the total
number of shares covered by the Option shall become exercisable after the first
anniversary of the Grant Date; (c) an additional one-fifth of the total number
of shares covered by the Option shall become exercisable after the second
anniversary of the Grant Date; (d) an additional one-fifth of the total number
of shares covered by the Option shall become exercisable after the third
anniversary of the Grant Date; (e) an additional one-fifth of the total number
of shares covered by the Option shall become exercisable after the fourth
anniversary of the Grant Date; (f) the remaining one-fifth of the total number
of shares covered by the Option shall become exercisable after the fifth
anniversary of the Grant Date. The Option shall not be exercised for any
fractional shares. If the Optionee does not exercise the Option in any one year
with respect to the full number of shares to which the Optionee is entitled in
that year, the Optionee's rights shall be cumulative and the Optionee may
purchase those shares in any subsequent year during the term of the Option.

                2.3 Limitations on Right to Exercise. The Option may not be
exercised unless at the time of such exercise the Optionee is either employed by
or serving as a director or consultant to, the Company or any subsidiary of the
Company and has been so employed or has so served continuously since the date
the Option was granted.

                2.4 Nontransferability. The Option may not be assigned or
transferred by the Optionee, either voluntarily or by operation of law, and may
be exercised only by the Optionee.

                2.5 Purchase of Shares. Unless the Board of Directors determines
otherwise, the Option may be exercised only upon receipt by the Company of the
Option Exercise Form, in the form attached as Exhibit B, from the Optionee
stating the Optionee's intention to exercise, specifying the number of shares as
to which the Optionee desires to exercise the Option and the date on which the
Optionee desires to complete the transaction, and, unless in the opinion of
counsel for the Company such a representation is not required in order to comply
with the Securities Act of 1933, as amended, containing a representation that it
is the Optionee's intention to acquire the shares for investment and not with a
view to distribution. Unless the Board of Directors determines otherwise, on or
before the date specified for completion of the purchase of the shares, the
Optionee must pay the Company the full purchase price of such shares in cash. No
shares shall be issued until full payment has been made and the Optionee has
executed and delivered to the Company either the Stock Transfer Restriction
Agreement substantially in the form attached to this Agreement as Exhibit C (the
"Restriction Agreement") or at the Company's discretion any applicable
shareholders or stock transfer restriction agreement as in effect at that time
(which agreement may at the Company's discretion contain provisions similar to
the Restriction Agreement.) The Optionee shall have none of the rights of a
shareholder until a certificate for the shares is issued to the Optionee. Upon
notification of the amount due (if any), the Optionee shall pay to the Company
in cash amounts necessary to satisfy applicable federal, state and local
withholding tax requirements. If additional withholding becomes required beyond
any amount deposited before delivery of the certificates, the Optionee shall pay
such amount to the Company on demand. If the Optionee fails to pay the amount
demanded, the Company may withhold that amount from other amounts payable by the
Company to the Optionee, including salary, subject to applicable law.

                2.6 Stock Splits; Combinations; Dividends. If, during the term
of the Option, the outstanding Common Stock of the Company is hereafter
increased or decreased or changed into or exchanged for a different number or
kind of shares or other securities of the Company by reason of any stock split,
combination of shares, reclassification, or dividend payable in shares,
appropriate adjustment shall be made by the Board of Directors in the number and
kind of shares subject to the Option, or the unexercised portion thereof, so
that the Optionee's proportionate interest before and after the occurrence of
the event is maintained.

                                       2

Notwithstanding the foregoing, the Board of Directors shall have no obligation
to effect any adjustment that would or might result in the issuance of
fractional shares, and any fractional shares resulting from any adjustment may
be disregarded or provided for in any manner determined by the Board of
Directors. Any such adjustments made by the Board of Directors shall be
conclusive.

                2.7 Mergers, Reorganizations, Etc. In the event of a merger,
consolidation, plan of exchange, acquisition of property or stock, separation,
reorganization or liquidation to which the Company or a subsidiary is a party,
or a sale of all or substantially all of the Company's assets (each, a
"Transaction"), the Company, in its sole discretion and to the extent possible
under the structure of the Transaction, may provide a 30-day period prior to the
consummation of the Transaction during which the Optionee shall have the right
to exercise the Option to the extent shares subject to the Option are or would
be vested as of the date of consummation of the Transaction. Upon expiration of
such 30-day period all further rights to purchase shares pursuant to the Option
shall terminate.

        3. Stock Transfer Restriction Agreement. The Optionee agrees that any
shares acquired upon exercise of the Option shall be subject to a shareholder's
or stock transfer restriction agreement, a copy of which will be provided to the
Optionee at the time the Option is exercised. The exercise of the Option shall
not be effective until the Optionee has signed and delivered to the Company such
stock transfer restriction agreement.

        4. Approvals. The obligations of the Company under this Agreement are
subject to the approval of state and federal authorities or agencies with
jurisdiction in the matter. The Company will use its best efforts to take steps
required by state or federal law or applicable regulations, including rules and
regulations of the Securities and Exchange Commission and any stock exchange on
which the Company's shares may then be listed, in connection with issuance or
sale of any shares purchased upon exercise of the Option. The foregoing
notwithstanding, the Company shall not be obligated to issue or deliver Common
Stock under this Agreement if such issuance or delivery would violate applicable
state or federal securities laws.

        5. No Contract Rights. Nothing in the Plan or this Agreement shall
confer upon the Optionee any right to be retained by the Company or any
subsidiary or to the continuation, extension, renewal, or modification of any
compensation, contract, agreement, or arrangement with or by the Company or any
subsidiary, or alter, modify, change or terminate any right of the Company or
any subsidiary under any contract, agreement or arrangement with the Optionee.

        6. Successors. This Agreement shall be binding upon and shall inure to
the benefit of any successor or successors of the Company.

date written above until paid, all in accordance with the following terms and
conditions:
