                                   EXHIBIT 4.7

                              DATA DIMENSIONS, INC.

                       NONSTATUTORY STOCK OPTION AGREEMENT

     Data Dimensions, Inc., a Delaware corporation (the "Corporation"), through
its Board of Directors, has granted to Peter A. Allen ("Optionee") an option
(the "Option") to purchase 50,000 shares of the Corporation's Common Stock (the
"Option Shares") at a price of $13.25 per share (the "Option Price"). The Option
has been granted to Optionee on December 7, 1998 (the "Grant Date").

      1. NATURE OF THE OPTION. The Option is a nonstatutory option and is not
intended to qualify as an Incentive Stock Option as defined in Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code").

      2. DATE EXERCISABLE; VESTING.

         2.1 The Option shall become fully exercisable at the end of the twelve
(12) month period of Optionee's continuous employment with the Corporation
following the Grant Date (the "Vesting Date"). The right to purchase the Option
Shares shall continue for a period of five (5) years from the Vesting Date.
Subject to earlier termination as provided in Section 4 below, any portion of
the Option Shares not exercised at the close of business on the fifth (5th)
anniversary of the Vesting Date shall thereafter be cancelled and Optionee shall
have no further right to purchase such cancelled Option Shares.

         2.2 In the event Optionee for any reason ceases to be an employee of
the Corporation prior to the Vesting Date, whether by dismissal, resignation,
death, disability or otherwise, the Option shall not be exercisable.

         2.3 The Option shall become immediately exercisable for the full number
of Option Shares upon the occurrence of an event whereby any person or entity,
including any "person" as such term is used in Section 13(d)(3) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), becomes the
"beneficial owner," as defined in the Exchange Act, of Common Stock representing
fifty percent (50%) or more of the combined voting power of voting securities of
the Corporation.

      3. EXERCISE OF OPTION.

         3.1 The Option may be exercised in whole or in part by delivery to the
Corporation, from time to time, of written notice, signed by Optionee,
specifying the number of Option Shares that Optionee then desires to purchase,
together with cash or check payable to the order of the Corporation, or other
form of payment acceptable to the Corporation's Board of Directors, for an
amount of United States dollars equal to the Option Price of such Option Shares.

         3.2 As soon as practicable after any exercise in whole or in part of
the Option by Optionee, the Corporation shall deliver to Optionee or, at
Optionee's request, Optionee's designated broker, a certificate or certificates
for the number of shares of Common Stock with respect to which the Option was so
exercised, registered in Optionee's name.

      4. DURATION OF OPTION. The Option, to the extent not previously exercised,
shall terminate upon the earliest of the following dates:

         4.1 The close of business on the fifth (5th) anniversary of the Vesting
Date;

         4.2 Three (3) months after the date of Optionee's termination of
employment with the Corporation, in the event such termination is for any reason
other than Optionee's disability (as defined in the Employment Agreement between
Optionee and the Corporation) or death;

         4.3 One year after Optionee's termination of employment, if such
termination is by reason of Optionee's disability (as defined in the Employment
Agreement between Optionee and the Corporation) or death;

         4.4 The date of any sale, transfer or hypothecation, or any attempted
sale, transfer or hypothecation, of such Option in violation of Section 5; or

         4.5 Upon the occurrence of any Terminating Event as defined in the
Corporation's 1997 Stock Option Plan, as such Plan may be amended from time to
time (the "1997 Plan").

      5. NONTRANSFERABILITY.

         5.1 The Option is not transferable by Optionee otherwise than by
testamentary will, the laws of descent and distribution, or qualified domestic
relations order (as defined in the Plan) and, during Optionee's lifetime, may be
exercised only by Optionee or Optionee's guardian or legal representative or the
transferee pursuant to a qualified domestic relations order. No assignment or
transfer of the Option, whether voluntary, involuntary, or by operation of law
or otherwise, except by testamentary will, the laws of descent and distribution,
or qualified domestic relations order, shall vest in the

                                       40
<PAGE>

assignee or transferee any interest or right, but immediately upon any attempt
to assign or transfer the Option, the Option shall terminate and be of no
further force or effect.

         5.2 Whenever the word "Optionee" is used in any provision of this
Agreement under circumstances when the provision should logically be construed
to apply to the Optionee's guardian, legal representative, executor,
administrator, or the person or persons to whom the Option may be transferred by
testamentary will, the laws of descent and distribution, or qualified domestic
relations order, the word "Optionee" shall be deemed to include such person or
persons.

      6. NO RIGHTS AS SHAREHOLDER PRIOR TO EXERCISE. Optionee shall not be
deemed for any purpose to be a shareholder of the Corporation with respect to
any Option Shares as to which the Option has not been exercised.

      7. ADJUSTMENTS UPON RECAPITALIZATION OR REORGANIZATION.

         7.1 In the event of a material alteration in the capital structure of
the Corporation on account of a recapitalization, stock split, reverse stock
split, stock dividend or otherwise, the Option shall be subject to adjustment by
the Board of Directors on the same basis that options issued pursuant to the
1997 Plan are adjusted as a result of such event.

         7.2 In the event of a reorganization, as defined in the 1997 Plan, the
Option shall be assumed or an option substituted therefor on the same basis that
options issued pursuant to the 1997 Plan are assumed or substituted for as a
result of such reorganization.

      8. MISCELLANEOUS PROVISIONS.

         8.1 TAXATION UPON EXERCISE OF OPTION. Optionee understands that
pursuant to certain provisions of the Code, upon exercise of the Option,
Optionee may recognize income for tax purposes in an amount equal to the excess
of the then fair market value of the Option Shares over the Option Price. The
Corporation may be required to withhold tax from Optionee's current compensation
with respect to such income; to the extent that Optionee's current compensation
is insufficient to satisfy the withholding tax liability, the Company may
require the Optionee to make a cash payment to cover such liability as a
condition of exercise of the Option.

         8.2 GOVERNING LAW. This Agreement shall be administered, interpreted
and enforced under the internal laws of the State of Washington, without regard
to conflicts of laws thereof.

       IN PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH
       DEPOSITARY OR A NOMINEE THEREOF, EXCEPT IN THE LIMITED CIRCUMSTANCES
       DESCRIBED IN THE INDENTURE.

     BURLINGTON NORTHERN SANTA FE CORPORATION, a corporation duly organized and

Interest Payment Date to which interest has been paid or duly provided for,
semi-annually on January 15 and July 15 in each year, commencing January 15,
2002, at the rate of 6.750% per annum, until the principal hereof is paid or

option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register.

     Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes

shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

                                                                  As Trustee

This Security is one of a duly authorized issue of securities of the Company
(herein called the "Securities"), issued and to be issued in one or more series
under an Indenture, dated as of December 1, 1995 (herein called the "Indenture",
which term shall have the meaning assigned to it in such instrument), between
the Company and Bank One Trust Company, N.A., as successor to The First National
Bank of Chicago, as Trustee (herein called the "Trustee", which term includes
any successor trustee under the Indenture), and reference is hereby made to the
Indenture for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee and the Holders of
the Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Security is one of the series designated on
the face hereof and will initially be offered in the principal amount of
$400,000,000. The Company may, without the consent of the Holders, issue
additional Securities and thereby increase such principal amount in the future,
on the same terms and conditions and with the same CUSIP number as this
Security.

     The Securities of this series are subject to redemption upon not less than
30 and not more than 60 days' notice by mail, at any time, as a whole or in
part, at the election of the Company, at a redemption price equal to the greater
of (i) 100% of their principal amount or (ii) the sum of the present values of
the remaining scheduled payments of principal and interest thereon discounted to
the date of redemption on a semiannual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Rate (as defined in the Officers'
Certificate establishing the Securities of this series), plus 20 basis points,
plus in either case accrued interest to the date of redemption.

     In the event of redemption of this Security in part only, a new Security or
Securities of this series and of like tenor for the unredeemed portion hereof
will be issued in the name of the Holder, upon the cancellation hereof.

     The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Security or certain restrictive covenants and Events of
Default with respect to this Security, in each case upon compliance with certain
conditions set forth in the Indenture.

     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities of this series at the time Outstanding shall have made written
request to the Trustee to institute proceedings in respect of such Event of
Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee
shall not have received from the Holders of a majority in principal amount of
Securities of this series at the time Outstanding a direction inconsistent with
such request, and the Trustee shall have failed to institute any such
proceeding, for 60 days after receipt of such notice, request and offer of
indemnity. The foregoing shall not apply to any suit instituted by the Holder of
this Security for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed
herein.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Security at the times, place and rate, and in the coin or currency,
herein prescribed.

                                      E-3

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company in any place where the principal of and any premium and
interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series
and of like tenor, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Security is registered as the owner hereof for all
purposes, whether or not this Security is overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.
