Item 1.   Changes in Control of Registrant
- ------    --------------------------------

     On September 21, 1999, Inland Resources Inc. ("Inland"), and its
subsidiaries, Inland Production Company ("IPC") and Inland Refining, Inc.
("Refining"), entered into an Exchange Agreement (the "Exchange Agreement") with
Trust Company of the West, as Sub-Custodian for Mellon Bank for the benefit of
Account No. CPFF 873-3032 ("Fund V"), TCW Portfolio No. 1555 DR V Sub-Custody
Partnership, L.P. ("Portfolio") (Portfolio and Fund V collectively being
referred to as "TCW"), Inland Holdings LLC ("Holdings") and Joint Energy
Development Investments II Limited Partnership ("JEDI"), pursuant to which Fund
V and Portfolio agreed to exchange certain indebtedness and warrants to purchase
shares of Inland's common stock, $.001 par value per share ("Common Stock"), for
shares of Common Stock and two new series of Preferred Stock of Inland, and JEDI
agreed to exchange 100,000 shares of Series C Preferred Stock of Inland for
shares of Common Stock and a third new series of Preferred Stock of Inland (the
"Recapitalization").

     Pursuant to the Exchange Agreement, Fund V agreed to exchange $75 million
in principal amount of subordinated indebtedness of IPC plus accrued interest of
$5.7 million and Portfolio agreed to exchange warrants to purchase 158,512
shares of Common Stock for the following securities of Inland issued to
Holdings, whose members are Fund V and Portfolio: (i) 10,757,747 shares of newly
designated Series D Redeemable Preferred Stock of Inland ("Series D Preferred
Stock"), (ii) 5,882,901 shares of newly designated Series Z Convertible
Preferred Stock of Inland ("Series Z Preferred Stock") and (iii) 11,642,949
shares of Common Stock; and JEDI agreed to exchange the 100,000 shares of
Inland's Series C Cumulative Convertible Preferred Stock ("Series C Preferred
Stock") owned by JEDI, together with all accumulated dividends thereon, for (i)
121,973 shares of newly designated Series E Redeemable Preferred Stock of Inland
("Series E Preferred Stock") and (ii) 2,920,975 shares of Common Stock.  The
Series C Preferred Stock had a liquidation preference of $100 per share and was
required to be redeemed at a price of $100 per share not later than January 21,
2008.  The Series C Preferred Stock also bore dividends at a rate of $10 per
share, and there were $2.2 million of accumulated dividends as of the date of
the Exchange Agreement.

     Inland, Holdings, Fund V and JEDI also entered into a Shareholders
Agreement (the "Shareholders Agreement") and a Registration Rights Agreement
(the "Registration Agreement") on September 21, 1999 with Pengo Securities
Corp., Smith Energy Partnership, Randall D. Smith, Jeffrey A. Smith, Barbara
Stovall Smith, John W. Adams and Arthur J. Pasmas (collectively the "Smith
Group").  The Shareholders Agreement sets forth certain rights among Holdings,
JEDI and the Smith Group relating to transfers of shares and certain voting
rights. The Registration Agreement provides Holdings, JEDI and the Smith Group
certain demand and piggy-back registration rights for the registration of their
respective shares under the Securities Act of 1933 (the "1933 Act"), at the
expense of Inland.

     Following closing of the Exchange Agreement, Holdings owns 11,642,949
shares of Common Stock, representing approximately 50.4% of the outstanding
shares of Common Stock, and JEDI owns 2,920,975 shares of Common Stock,
representing approximately 12.6% of the outstanding shares of Common Stock.  In
connection with the Exchange Agreement, the Articles of Incorporation

                                      -2-
<PAGE>

(the "Articles") of Inland were amended to designate the Series D Preferred
Stock, Series E Preferred Stock and Series Z Preferred Stock. The Articles, as
so amended, provide that the Common Stock, Series D Preferred Stock, Series E
Preferred Stock and Series Z Preferred Stock shall vote together as a single
class and not as a separate voting group or class, except as mandated by law or
as expressly set forth in the Articles. The Series D Preferred Stock and the
Series E Preferred Stock vote with the Common Stock on a share-for-share basis
and the Series Z Preferred Stock votes with the Common Stock on a share-for-
share basis, but is entitled to the number of votes which would be equal to the
total number of shares of Common Stock into which the Series Z Preferred Stock
would be convertible, which is presently one share of Common Stock for each
share of Series Z Preferred Stock. Pursuant to the Articles, as amended, the
total number of votes of the combined class of Common Stock, Series D Preferred
Stock, Series E Preferred Stock and Series Z Preferred Stock presently
outstanding is 39,856,310 votes, of which 28,283,597 votes (representing
approximately 71% of the total) are owned by Holdings, and 3,042,948 votes
(representing approximately 7.6% of the total) are owned by JEDI. TCW Asset
Management Company has the power, together with Trust Company of the West (as
sub-custodian for Mellon Bank), to vote and dispose of the securities owned by
Holdings.

     Under the Exchange Agreement, if any of the outstanding options and
warrants granted to Inland's management, which are exercisable for 1,291,651
shares of Common Stock, are exercised, Holdings will be granted an option at the
same exercise price to acquire 200% of the shares issued pursuant to such
exercised option or warrant, and JEDI will be granted an option at the same
exercise price to acquire one-third of the shares issued pursuant to such
exercised option or warrant.

     Inland has agreed that so long as Holdings controls or holds Series D
Preferred Stock with a liquidation preference of at least $25 million, Inland
will not engage in various activities without the prior written approval of
Holdings unless such activity had been contemplated by the latest budget
approved by Holdings, including making individual expenditures over $25,000,
conveying assets with a value exceeding $25,000, approving compensation and
benefit packages for officers and directors, borrowing money in excess of
$25,000, approving the hiring or termination of management employees and
commencing or settling any litigation in amounts in excess of $25,000. Inland
paid all of the expenses of Holdings and JEDI in connection with the Exchange
Agreement, and $25,000 collectively to Portfolio and Fund V and $25,000 to JEDI
as restructuring fees.

     One of the conditions to closing of the Exchange Agreement was that Inland
receive an opinion of an investment banking firm that the Series D Preferred
Stock, Series E Preferred Stock, Series Z Preferred Stock and Common Stock
issued to Holdings and JEDI (the "Restructuring Consideration") in exchange for
indebtedness, warrants and Series C Preferred Stock was fair, from a financial
point of view, to the existing public holders of Inland's Common Stock. McDonald
Investments Inc. delivered a fairness opinion to Inland's Board of Directors
dated September 14, 1999 stating that based on the assumptions and conditions
set forth in their opinion, it was McDonald's opinion as of that date that the
Restructuring Consideration was fair, from a financial point of view, to the
unaffiliated holders of Inland's Common Stock. McDonald's opinion was expressly
conditioned, among other things, upon consummation of an amendment to IPC's and
Inland's existing Amended and Restated Credit Agreement to, among

                                      -3-
<PAGE>

other things, increase IPC's and Inland's borrowing base from $70 million to
$83.5 million and to provide that no redetermination of the borrowing base would
be made prior to October 1, 2000. Such amendment to the Amended and Restated
Credit Agreement occurred September 21, 1999, concurrently with the closing of
the Recapitalization.

     Under the amended Articles, the Series D Preferred Stock accrues dividends
at a rate of $0.16875 per share per quarter if paid in cash on a current basis
or $0.2109375 per share per quarter if accumulated and not paid on a current
basis.  Dividends are required to be paid on each December 30, March 30, June 29
and September 29, commencing December 30, 1999.  Dividends also accrue and will
be payable on any unpaid dividends at a rate of 11.25% per annum.  No dividends
may be declared or paid on Common Stock or any other series of preferred stock
while there are any accrued and unpaid dividends on the Series D Preferred
Stock.  The Series D Preferred Stock also has liquidation preference over all
other classes and series of stock, in an amount equal to $7.50 per share.  The
Series D Preferred Stock may be redeemed at any time by Inland for a redemption
price of $7.50 per share and must be redeemed upon the earlier of September 21,
2004 or the repayment in full of Inland's existing senior credit facility.  In
addition to voting as a class with the Common Stock, Series E Preferred Stock
and Series Z Preferred Stock, as discussed above, holders of 75% of the
outstanding shares of Series D Preferred Stock, voting as a separate voting
group, must approve any modification to the dividend rates, liquidation
preferences or other privileges of the Series D Preferred Stock, any merger or
consolidation of Inland in which Inland is not the surviving entity, any
transaction which will result in the holders of voting stock of Inland
immediately prior to such transaction owning less than 50% of the outstanding
voting stock of Inland after the transaction or the sale or other transfer of
substantially all of the assets of Inland.  Further, a majority of the
outstanding shares of Series D Preferred Stock, voting as a separate voting
group, have the right to (i) elect four members of the Board for as long as at
least 37.5% of the original shares of Series D Preferred Stock remain
outstanding; (ii) three members of the Board for as long as at least 25%, but
less than 37.5% remain outstanding; (iii) two members of the Board for as long
as at least 12.5%, but less than 25% remain outstanding; and (iv) one member of
the Board for as long as any shares of Series D Preferred Stock remain
outstanding even though they are less than 12.5% of the original shares issued.
As the number of members that may be elected by holders of Series D Preferred
Stock decline, the holders of Common Stock are entitled to elect those members
to the Board.  Cumulative voting and preemptive rights are expressly denied to
the holders of Series D Preferred Stock.

     Under the amended Articles, the Series E Preferred Stock accrues dividends
at a rate of $2.3125 per share per quarter if paid in cash on a current basis or
$2.875 per share per quarter if accumulated and not paid on a current basis.
Dividends are required to be paid on each December 30, March 30, June 29 and
September 29, commencing December 30, 1999.  Dividends also accrue and will be
payable on any unpaid dividends at a rate of 11.50% per annum.  No dividends may
be declared or paid on Common Stock or the Series Z Preferred Stock while there
are any accrued and unpaid dividends on the Series E Preferred Stock.  The
Series E Preferred Stock also has liquidation preference over all other classes
and series of stock, except the Series D Preferred Stock, in an amount equal to
$100.00 per share.  The Series E Preferred Stock may be redeemed at any time by
Inland for a redemption price of $100.00 per share and must be redeemed upon the
earlier of

                                      -4-
<PAGE>

September 21, 2006 or the redemption of all outstanding shares of Series D
Preferred Stock. In addition to voting as a class with Common Stock, Series D
Preferred Stock and Series Z Preferred Stock, as discussed above, holders of 75%
of the outstanding shares of Series E Preferred Stock, voting as a separate
voting group, must approve any modification to the dividend rates, liquidation
preferences or other privileges of the Series E Preferred Stock; any merger or
consolidation of Inland in which Inland is not the surviving entity or any
transaction which will result in the holders of voting stock of Inland
immediately prior to such transaction owning less than 50% of the outstanding
voting stock of Inland after the transaction, unless, in either case, the
holders of Series E Preferred Stock receives shares with substantially the same
rights and preferences as correspond to the Series E Preferred Stock; any merger
in which the holders of Common Stock receive consideration in exchange for their
Common Stock other than Common Stock of the surviving corporation junior to the
securities issued to the holders of Series E Preferred Stock; or the sale or
other transfer of substantially all of the assets of Inland unless, so long as
the Series D Preferred Stock is outstanding, at least 60% of the Series E
Preferred Stock is redeemed or the holders of Series E Preferred Stock receive
an amount equal to 60% of 10/85ths of the total consideration received by the
holders of Series D Preferred Stock and Series E Preferred Stock in the same
form of consideration as that received by the holders of Series D Preferred
Stock. Further, a majority of the outstanding shares of Series E Preferred
Stock, voting as a separate voting group, have the right to elect one member of
the Board. Cumulative voting and preemptive rights are expressly denied to the
holders of Series E Preferred Stock.

     The Series Z Preferred Stock ranks on an equivalent basis with the Common
Stock with respect to all matters, except the Series Z Preferred Stock has a
liquidation preference of $.002 per share which ranks ahead of the Common Stock,
and after receiving this liquidation preference, the Series Z Preferred Stock
will share in any remaining assets on liquidation pro rata on an as-converted
basis with the holders of Common Stock.  Currently, the Series Z Preferred Stock
is convertible at a rate of one share of Common Stock for each share of Series Z
Preferred Stock and shall be deemed automatically converted into that number of
shares immediately upon the Articles being further amended to increase the
number of authorized shares of Common Stock to such a number that will permit
such conversion.  It is anticipated that Inland will call a meeting of
stockholders prior to the end of 1999 to vote on such amendment.

     Under the Shareholders Agreement, Holdings agreed to provide JEDI and the
Smith Group with certain rights to sell their shares if Holdings desires to sell
shares owned by it, and each of JEDI and the Smith Group granted Holdings the
right to require JEDI and the Smith Group to sell an equivalent number of their
shares on the same terms and conditions to any purchaser to whom Holdings
desires to sell a portion of its shares.  Holdings, Fund V and Portfolio also
agreed with JEDI and the Smith Group that if Holdings, Fund V or Portfolio
endeavored to purchase any shares of Common Stock from a person not a party to
the Shareholders Agreement, Holdings, Fund V and Portfolio will offer to
purchase on a pro rata basis from JEDI and the Smith Group an equal number of
shares which are being purchased from the person not a party to the Shareholders
Agreement. Holdings, JEDI and the Smith Group also agreed with each other to
vote their respective shares to ensure that the Board of Inland would consist of
six members and that one member would be

                                      -5-
<PAGE>

designated for election to the Board by the holders of Common Stock and Series Z
Preferred Stock. Each of JEDI and Holdings further agreed not to vote their
respective shares of Common Stock and Series Z Preferred Stock in the election
of such one designated Board member for as long as they owned Series D Preferred
Stock or Series E Preferred Stock and the Smith Group continued to hold 10% or
more of the combined outstanding shares of Common Stock and Series Z Preferred
Stock, provided, that if Holdings does not at such time hold enough Series D
Preferred Stock to entitle it to elect four members to the Board, Holdings will
be entitled to vote an amount of its common Stock proportionate to the reduction
in number of directors it is entitled to designate as a holder of Series D
Preferred Stock. Each member of the Smith Group agreed not to vote their shares
of Common Stock for the election of the one board member to be designated for
election by the holders of Common Stock and Series Z Preferred Stock as long as
it continued to hold 10% or more of the combined outstanding shares of Common
Stock and Series Z Preferred Stock.

     The current members of the Board are John D. Lomax (Chairman), Bill I.
Pennington (Chief Executive Officer and Chief Financial Officer of Inland), John
E. Dyer (President and Chief Operating Officer of Inland), Kyle R. Miller and T
Brooke Farnsworth.  Messrs. Lomax, Miller and Farnsworth were existing members
of the Board, and Messrs. Pennington and Dyer were appointed to the Board on
September 23, 1999 to fill two vacancies resulting from resignations from the
Board.

     In connection with the Exchange Agreement, Inland entered into the
Registration Agreement with Holdings, Portfolio, JEDI and the Smith Group
pursuant to which Inland granted Holdings, JEDI and the Smith Group piggy-back
registration rights to include their shares on any registration statement filed
by Inland under the 1933 Act, subject to standard underwriters' kick-out clauses
and other conditions.  Inland also granted to Holdings, JEDI and the Smith Group
demand registration rights which entitle Holdings to require Inland to file up
to three registration statements to register its shares, entitle JEDI to require
Inland to file up to two registration statements to register its shares and
entitle the Smith Group to require Inland to file one registration statement to
register its shares. Inland will be responsible for paying the costs and
expenses associated with all registration statements, including the fees of one
law firm acting as counsel to the holders requesting registration, but excluding
underwriting discounts and commissions and any other expenses of the party
requesting registration.

Item 5.   Other Events.
- ------    -------------

     One of the conditions to the closing of the Exchange Agreement was that
Inland's senior lenders would enter into a restructuring of the senior credit
facility acceptable to Holdings, JEDI and Inland.  As a result, effective as of
September 21, 1999, Inland and IPC entered into the Second Amended and Restated
Credit Agreement (the "ING Credit Agreement") with ING (U.S.) Capital
Corporation, U.S. Bank National Association and Meespierson Capital Corporation
(the "Senior Lenders") pursuant to which the Senior Lenders agreed to increase
the borrowing base under the ING Credit Agreement from $73.25 million to $83.5
million, and remove the amortization schedule and provide that the outstanding
principal balance shall be due and payable in full on October 1, 2001. Upon the
closing of the ING Credit Agreement, IPC borrowed $3.0 million, bringing the
total

                                      -6-
<PAGE>

outstanding principal balance to $73,915,000 at September 21, 1999. IPC has $4.0
million available for letters of credit within the $83.5 million borrowing base,
of which $2.34 million were outstanding at September 21, 1999. Interest accrues,
at IPC's option, at either (i) 2% (instead of 0.5%) above the prime rate or (ii)
3% (instead of 1.75%) above the LIBOR rate. At September 27, 1999, all
$73,915,000 outstanding principal was under the LIBOR option at an effective
rate of 8.52% through December 27, 1999. The borrowing base will be redetermined
on October 1, 2000 and April 1, 2001 and may be redetermined at the option of
the Senior Lenders one additional time after October 1, 2000. Upon
redetermination, if the borrowing base is lower than the outstanding principal
balance then drawn, IPC must immediately pay the difference. Within 30 days
after closing, IPC is required to enter into a hedge for at least 50% of its
projected oil and gas production through December 31, 2001 and 25% for the year
ended December 31, 2002. IPC paid a facility fee of $150,000 and an additional
fee of $208,000 to the Senior Lenders at closing. IPC must also pay a facility
fee equal to 0.50% of the borrowing base on April 1, 2001 and again on September
30, 2001. The Senior Lenders will also receive a fee equal to 1% of the
borrowing base on October 1, 2000 if ING (U.S.) Capital Corporation continues to
be a member of the Senior Lenders at September 30, 2000. The ING Credit
Agreement continues to contain standard affirmative, negative and financial
covenants.

                 automatically adjusted, such that the holders of the Series D

                              Articles of Incorporation of the Corporation for
                              which the holders of shares of Series E Preferred

                              of such event shall be automatically adjusted,
                              such that the holders of the Series E Preferred

                              contained herein and in addition to any special
                              voting provisions set forth in any applicable law,

                    form of consideration as that received by the holders of the
                    Series D Preferred Stock; provided that the consideration
                    received by holders of the Series E Preferred Stock under
                    this clause (iii)(B) shall not have a value less than the
                    amount holders of the Series E Preferred Stock would receive

                    separately as a voting group or class, to elect one of the

                    shares of Series E Preferred Stock remain outstanding, the
                    holders of the Corporation's Common Stock shall be entitled
                    to elect one (1) of the members of the Corporation's Board
                    theretofore elected by the holders of the Series E Preferred
                    Stock, subject to the right of any other class or series of
                    capital stock of the Corporation to elect one or more
                    members of the Corporation's Board.  If the number of
                    members of the Board increases to a number greater than six
                    (6) at any time or from time to time by action of the
                    Corporation or its shareholders while any shares of Series E

                    Preferred Stock shall have the right to elect that number of
                    directors equal to one-sixth of the directors comprising the

                    comprising the Board is not an integer, the next higher
                    integer).  A director elected by the holders of Series E

                           --------
                    time as no shares of Series E Preferred Stock remain
                    outstanding, immediately upon the election of his successor
                    by the holders of stock other than Series E Preferred Stock.
                    The holders of the Series E Preferred Stock shall be
                    entitled at any time or from time to time to remove any
                    director who was appointed by such holders for any reason or
                    no reason whatsoever. Any such removal or election shall be
                    effective upon written notice thereof to the Corporation.
                    Except as otherwise provided by law, vacancies and newly
                    created directorships resulting from any increase in the
                    authorized number of directors may be filled by election by
                    the holders of the Series E Preferred Stock or by a majority
                    of the directors elected by the holders of the Series E
                    Preferred Stock pursuant to this subparagraph (iv)(d).

                    (ii) The holders of the Series E Preferred Stock, in lieu of
                    appointing a director to the Corporation's Board, shall have
                    the right to (A) receive prior notice of any proposed action
                    by the Corporation's Board or a committee thereof, and to
                    receive reasonable notice of and to attend and receive all
                    materials distributed for or at any meeting (including
                    telephonic meetings) of the Board and (B) receive promptly
                    after they are produced, all management reports and
                    management accounts relating to the Corporation.  A Board
                    observer appointed by holders of the Series E Preferred
                    Stock shall receive no compensation from the Corporation for
                    services as an observer, but shall be entitled to be
                    reimbursed by the Corporation for all reasonable costs and
                    expenses incurred in connection with his or her
                    participation in meetings or other activities of the Board.

               (e)  Cumulative voting by holders of Series E Preferred Stock is
                    expressly denied.

          Stock shall be entitled as a matter of right to subscribe or receive
          additional shares of any class of stock of the Corporation, whether
          now or hereafter authorized, or any bonds, debentures or other
          securities convertible into such stock, but such additional shares of
          stock or other securities convertible into stock may be issued or
          disposed of to such persons and on such terms as in the Board's
          discretion the Board shall deem advisable.

               made pursuant to paragraph (iv) hereof) in the same form and at
               the same rate as dividends are paid with respect to the Common
               Stock (treating each share of Series Z Preferred Stock as being
               equal to the number of shares of Common Stock into which each
               such share of Series Z Preferred Stock could be converted
               pursuant to the provisions of paragraph (iv) hereof, with such
               number determined as of the record date for the determination of
               holders of Common Stock entitled to receive such dividend).

     (ii)      LIQUIDATION RIGHTS.
               ------------------

               (a) In the event of any liquidation, dissolution or winding up of
               the Corporation, whether voluntary or involuntary, and after the
               payment or distribution to the holders of the Series D Preferred
               Stock and the Series E Preferred Stock of their full preferential
               amounts, the holder of each share of Series Z Preferred Stock
               then outstanding shall be entitled to be paid out of the assets
               of the Corporation available for distribution to its
               shareholders, whether such assets are capital, surplus or
               earnings, before any payment or declaration and setting apart for
               payment of any amount shall be made in respect of the Common
               Stock, an amount in cash equal to $.002 for each share of such
               Series Z Preferred Stock (the "Liquidation Value"). Such

               Liquidation Value shall be in addition to, and not in lieu of,
               any amount which such holder shall be entitled to receive under
               subparagraph (ii)(b) below.

               (b) After the payment or distribution to the holders of the
               Series D Preferred Stock, the Series E Preferred Stock and the

                                      -14-
<PAGE>

               then outstanding shall together be entitled to receive ratably,
               based on the number of shares of Common Stock into which the
               Series Z Preferred Stock is then convertible, all the remaining
               assets of the Corporation.

               (c) A consolidation or merger of the Corporation with or into any
               other corporation or corporations shall not be deemed to be a
               liquidation, dissolution or winding up of the Corporation as
               those terms are used in this paragraph (ii).

               (d) If upon any liquidation, dissolution or winding up of the
               Corporation, whether voluntary or involuntary, after the payment
               or distribution to the holders of the Series D Preferred Stock
               and the Series E Preferred Stock and any other preferred stock
               senior to the Series Z Preferred Stock of their full preferential
               amounts, the remaining assets to be distributed among the holders
               of Series Z Preferred Stock pursuant to subparagraph (a) shall be
               insufficient to permit the payment to such shareholders of the
               full preferential amounts required by such subparagraph, then all
               of the assets of the Corporation to be distributed shall be
               distributed ratably to the holders of outstanding Series Z
               Preferred Stock based on the number of shares held by each
               holder, and the holders of Common Stock shall receive no
               distribution upon such liquidation, dissolution or winding up of
               the Corporation.

     (iii)     NO REDEMPTION. The Series Z Preferred Stock is not redeemable by
               -------------
               the Corporation.

     (iv)      CONVERSION.  Shares of Series Z Preferred Stock shall be
               ----------
               converted into shares of Common Stock, on the terms and
               conditions set forth below:

               (a) Automatic Conversion.  At such time as the Articles of
                   --------------------
               Incorporation of the Corporation are amended to increase the
               authorized shares of Common Stock to permit the conversion of all
               of the Series Z Preferred Stock (the "Authorization Date"), each
                                                     ------------------
               share of Series Z Preferred Stock shall be automatically
               converted into the number of shares of Common Stock which result
               from dividing the Liquidation Value by the Conversion Price per
               share (as defined herein) in effect at the time of such
               conversion.  The initial Conversion Price per share shall be
               $.002, and such initial Conversion Price shall be subject to
               adjustment from time to time as provided herein (the "Conversion
                                                                     ----------
               Price").  Upon conversion of the Series Z Preferred Stock, each
               -----
               holder thereof shall be entitled to receive that number of shares
               of Common Stock into which such holder's shares of Series Z
               Preferred Stock has been converted.

               (b) Mechanics of Conversion.  Promptly following the
                   -----------------------
               Authorization Date, the Corporation shall mail to record holders
               of the Series Z Preferred Stock at the address for such holders
               on the books of the Corporation, notice of conversion of the
               Series Z Preferred Stock.  After notification of conversion by
               the Corporation, a holder of Series Z Preferred Stock shall
               surrender all such holder's certificates therefor, duly endorsed,
               at the office of the Corporation or at the offices of any
               transfer agent for the Series Z Preferred Stock or Common Stock
               (or at such other

                                      -15-
<PAGE>

               place designated by the Corporation in the notice of conversion).
               Upon receipt by the Corporation of a holder's Series Z Preferred
               Stock, the Corporation shall promptly issue and deliver to such
               holder of Series Z Preferred Stock a certificate or certificates
               for the number of shares of Common Stock to which such holder
               shall be entitled as aforesaid. Such conversion shall be deemed
               to have been made immediately prior to the close of business on
               the Authorization Date, and the person or persons whom the
               Corporation's records indicate are entitled to receive the shares
               of Common Stock issuable upon such conversion shall be treated
               for all purposes as the record holder or holders of such shares
               of Common Stock on the day immediately following such date. The
               certificate or certificates representing the shares of Common
               Stock issued upon such conversion shall contain the same
               restrictive legends, if any, included on the certificate or
               certificates of Series Z Preferred Stock surrendered, unless the
               shares of Common Stock issuable upon such conversion have been
               registered under the Securities Act of 1933, as amended, and
               qualified or registered under applicable state securities laws.

               (c) Adjustment for Stock Splits, Distributions or Subdivisions.
                   ----------------------------------------------------------
               If the Corporation shall at any time or from time to time after
               the first issuance of the Series Z Preferred Stock (the "Issuance
                                                                        --------
               Date") issue additional shares of Common Stock to holders of
               ----
               Common Stock pursuant to a share dividend, share distribution,
               subdivision, share split or reclassification, then concurrently
               with the effectiveness of such event, the Conversion Price in
               effect immediately prior to such event shall be proportionately
               decreased and the number of shares issuable on conversion of a
               share of Series Z Preferred Stock (the "Series Z Conversion
                                                       -------------------
               Shares") immediately prior to such event shall be proportionately
               ------
               increased.

               (d) Adjustments for Combinations or Consolidations.  If the
                   ----------------------------------------------
               Corporation shall at any time or from time to time after the
               Issuance Date, combine or consolidate, by reclassification,
               reverse split or otherwise, into a lesser number of shares of
               Common Stock, then concurrently with the effectiveness of such
               event, the Conversion Price in effect immediately prior to such
               event shall be proportionately increased and the number of
               Conversion Shares issuable upon conversion of the Series Z
               Preferred Stock immediately prior to such event shall be
               proportionately decreased.

               (e) Reorganization, Mergers, Consolidations or Sales of Assets.
                   ----------------------------------------------------------
               If at any time or from time to time there shall be a capital
               reorganization of the Common Stock (other than a subdivision,
               combination, reclassification or exchange of shares provided for
               elsewhere in this paragraph (iv)) or a merger or consolidation of
               the Corporation with or into another corporation, or the sale of
               all or substantially all of the Corporation's properties and
               assets to any other person, or a compulsory share exchange, then,
               as a part of such reorganization, merger, consolidation, sale or
               share exchange, provision shall be made so that the holders of a
               share of Series Z Preferred Stock shall thereafter be entitled to
               receive, upon conversion of Series Z Preferred Stock, the number
               of shares of stock or other securities or property receivable
               upon such reorganization, merger, consolidation, sale or share
               exchange by holders of the number of shares of Common Stock into
               which such share of

                                      -16-
<PAGE>

               Series Z Preferred Stock might have been converted immediately
               prior to such reorganization, merger, consolidation, sale or
               share exchange.

               (f) Certificate of Adjustment.  In each case of an adjustment or
                   -------------------------
               readjustment of the Conversion Price or the number of shares of
               Common Stock or other securities issuable upon conversion of
               Series Z Preferred Stock, the Corporation, at its expense, shall
               cause independent public accountants of recognized standing
               selected by the Corporation (who may be the independent public
               accountants then auditing the books of the Corporation) or the
               chief financial officer of the Corporation, at the Board's
               option, to compute such adjustment or readjustment in accordance
               with the Corporation's Articles of Incorporation and prepare a
               certificate showing such adjustment or readjustments to be
               mailed, by first class mail, postage prepaid, to each registered
               holder of Series Z Preferred Stock at the holder's address as
               shown in the Corporation's books.  The certificates shall set
               forth such adjustment or readjustment, showing in detail the
               facts upon which such adjustment or readjustment is based.

               (g) Notices of Record Date.  In the event (i) any taking by the
                   ----------------------
               Corporation of a record of the holders of any class of securities
               for the purpose of determining the holders thereof who are
               entitled to receive any dividend or other distribution, or (ii)
               any capital reorganization of the Corporation, any
               reclassification or recapitalization of the capital stock of the
               Corporation or any compulsory share exchange or any transfer of
               all or substantially all of the assets of the Corporation to, or
               any merger or consolidation with, any other any other entity or
               person, or any voluntary or involuntary dissolution, liquidation
               or winding up of the Corporation, the Corporation shall mail to
               each holder of Series Z Preferred stock at least thirty (30) days
               prior to the record date specified therein, a notice specifying
               (A) the date on which any such record is to be taken for the
               purpose of such dividend or distribution and a description of
               such dividend or distribution, (B) the date on which any such
               reorganization, reclassification or recapitalization, compulsory
               share exchange, transfer, consolidation, merger, dissolution,
               liquidation or winding up is expected to become effective and a
               description of such transaction, and (C) the time, if any, that
               is to be fixed as to when the holders of record of Common Stock
               (or other securities) shall be entitled to exchange their shares
               of Common Stock (or other securities) for securities or other
               property deliverable upon such reorganization, reclassification
               or recapitalization, compulsory share exchange, transfer,
               consolidation, merger, dissolution, liquidation or winding up.

               (h) No Fractional Shares.  No fractional shares of Common Stock
                   --------------------
               shall be issued upon the happening of any event as set forth in
               this subparagraph (b) above. In lieu of any fractional shares to
               which the holder would otherwise be entitled, the Corporation
               shall pay cash equal to (i) the product of such fraction
               multiplied by the fair market value of one share of the
               Corporation's Common Stock on the date of conversion, as
               determined by the closing price (or "last trade" price, if
               applicable) on the day prior to the date of conversion, if such
               shares are listed and trading primarily on one or more national
               securities exchange or (ii) the product of such fraction
               multiplied by a value of one share of the Corporation's Common
               Stock

                                      -17-
<PAGE>

               on the date of conversion, as determined by the Board in good
               faith using methods it considers appropriate.

               (i) Reservation of Stock Issuable Upon Conversion or for
                   ----------------------------------------------------
               Dividends.  From and after the Authorization Date, the
               ---------
               Corporation shall at all times reserve and keep available out of
               the authorized but unissued shares of Common Stock, solely for
               the purpose of effecting the conversion of shares of Series Z
               Preferred Stock, such number of its shares of Common Stock as
               shall from time to time be sufficient to effect the conversion of
               all outstanding shares of Series Z Preferred Stock; and if at any
               time thereafter the number of authorized but unissued shares of
               Common Stock shall not be sufficient to effect the conversion of
               all then outstanding shares of Series Z Preferred Stock, the
               Corporation will take such reasonable corporate action as may, in
               the opinion of its counsel, be necessary to increase its
               authorized but unissued shares of Common Stock to such number of
               shares as shall be sufficient for such purpose.

               (j) Notices Deemed Given.  Any notice required by the provisions
                   --------------------
               of this paragraph (iv) to be given to the holders of shares of
               Series Z Preferred Stock shall be deemed given five (5) business
               days after the same has been deposited in the United States mail,
               certified or registered mail, return receipt requested, postage
               prepaid, and addressed to each holder of record at such holder's
               address appearing on the books of the Corporation.

          (v)  VOTING RIGHTS.  Each holder of a share of Series Z Preferred
               -------------
               Stock shall be entitled to vote with the Common Stock on a share-
               for-share basis on all matters submitted to the shareholders of
               the Corporation for approval.  Holders of the Series Z Preferred
               Stock shall be entitled to such number of votes with respect to
               their Series Z Preferred Stock as shall equal the total number of
               shares of Common Stock into which their shares of Series Z
               Preferred Stock are then convertible (regardless of whether the
               holder thereof is then permitted to effect such conversion),
               rounded up to the nearest whole share.  Except as otherwise
               expressly provided herein or as mandated by law, the holders of
               shares of Common Stock, the Series D Preferred Stock, the Series
               E Preferred Stock and the Series Z Preferred Stock shall vote
               together and not as separate voting groups or classes.  In the
               event voting as a separate voting group by the holders of Series
               Z Preferred Stock is expressly required by Washington law, any
               vote by the holders of Series Z Preferred Stock as a separate
               voting group shall be effective if approved by a majority of the
               outstanding shares of Series Z Preferred Stock.

          (vi) PREEMPTIVE RIGHTS.  Except as provided in paragraph (iv), no
               -----------------
               holder of any shares of Series Z Preferred Stock shall be
               entitled as a matter of right to subscribe or receive additional
               shares of any class of stock of the Corporation, whether now or
               hereafter authorized, or any bonds, debentures or other
               securities convertible into such stock, but such additional
               shares of stock or other securities convertible into stock may be
               issued or disposed of by the Board to such persons and on such
               terms as in the Board's discretion the Board shall deem
               advisable.

                             ARTICLE VI - DIRECTORS

   1.   The number of directors of the Corporation shall be fixed as provided
by the Bylaws and may be changed from time to time by amending the Bylaws, as
then provided, but the number of directors shall be not less than three (3).

   2.   If the office of any director becomes vacant by reason of death,
resignation, removal, disqualification, or otherwise, the directors may, by the
affirmative vote of the majority of the remaining directors, though less than a
quorum, choose a successor or successors who shall hold office for the unexpired
term.

                                      -19-
<PAGE>

The Board of Directors are authorized to increase the number of persons to
comprise the Board of Directors in any period between annual shareholders'
meetings by the affirmative vote of a majority of the directors; provided,
however, that without the unanimous consent of all directors, the number of
directors who comprise the Board of Directors shall not be increased by more
than two (2) persons within any twelve (12) month period.

If the Board of Directors is divided into classes and in the event of any
increase or decrease in the authorized number of directors, (1) each director
then serving as such shall nevertheless continue as a director of the class of
which he is a member until the expiration of his term, or upon his earlier
resignation, removal from office, or death, (2) the newly created or eliminated
directorships resulting from such increase or decrease shall be allocated by the
Board of Directors among the three classes of directors so as to maintain equal
classes to the extent possible, and (3) in the event such decrease in the
authorized number of directors makes the total number of directors less than
nine (9), then the Board of Directors shall become declassified and the
directors remaining in office shall continue their terms until the next annual
meeting of shareholders, at which time all of said remaining directors shall be
re-elected to one year terms or until their successors are duly elected and
qualified.

     3.   When the Board of Directors shall consist of nine (9) or more members,
in lieu of electing the entire number of directors annually, the Board of
Directors of the Corporation shall be divided into three classes.  The method of
classification shall be to assign the longest terms to those directors with the
most seniority as directors.  In the event there are more directors with
identical seniority than there are class positions to be filled, choices shall
be made by drawing of lots.  The classes shall be as follows: Class 1, Class 2,
and Class 3, which classifications shall be effective on the 1st day of the
month following the shareholders' meeting during which the number of members of
the Board of Directors is increased to nine (9) or more.  In such an event, the
term of office of directors in Class I shall expire at the first annual meeting
of shareholders after their election, that of Class 2 shall expire at the second
annual meeting after their election, and that of Class 3 shall expire at the
third annual meeting after their election.  At each annual meeting of
shareholders after such classification, the number of directors equal to the
number of the class whose term expires at the time of such meeting shall be
elected to hold office until the third succeeding annual meeting.  No
classification of directors shall be effective in the event the number of
members of the Board is reduced to fewer than nine (9).

     4.   In furtherance of and not in limitation of the powers conferred by the
laws of the State of Washington, the Board of Directors is expressly authorized
to make, alter, and repeal the Bylaws of the Corporation, subject to the power
of the shareholders of the Corporation to change or repeal such Bylaws.

     5.   The Corporation may enter into, contract, and otherwise transact
business as vendor, purchaser, or otherwise with its directors, officers, and
shareholders, and with the Corporation's association with firms and entities of
which they are or may become interested as directors, officers, shareholders,
members, or otherwise, as freely as if those such adverse interests did not
exist, even though the vote, action, or presence of such directors, officers, or
shareholders may be necessary to obligate the Corporation under such contracts
or transactions; and in the absence of fraud, no such contracts or transactions
shall be avoided and no such director, officer, or shareholder shall be held
liable to account to the Corporation, by reason of such adverse interests or by
reason of any fiduciary relationship to the Corporation arising out of such
office or stock ownership, for any profit or benefit realized by him through any
such contract or transaction; provided that in the case of directors and
officers of the Corporation (but not in the case of shareholders who are not
directors or officers), the nature of the interest of such directors or officers
be disclosed or known

                                      -20-
<PAGE>

to the Board of Directors of the Corporation at the meeting thereof at which
such contract or transaction was authorized or confirmed. A general notice that
a director or officer of the Corporation is interested in any Corporation,
association, firm, or entity, shall be sufficient disclosure as to such director
or officer with respect to all contracts and transactions with the Corporation,
association, fin-n, or entity.

     6.   Except as otherwise expressly set forth in these Articles, any
contract, transaction, or act of the Corporation or of the directors or of any
officers of the Corporation which shall be ratified by a quorum of the
shareholders of the Corporation at any annual meeting or any special meeting
called for such purpose, shall be as valid and binding as though ratified by
every shareholder of the Corporation.

     7.   A director of the Corporation shall not be personally liable to the
Corporation or its shareholders for monetary damages arising from any conduct as
a director, except this limitation on liability shall not apply to (i) acts or
omissions involving intentional misconduct by the director or a knowing
violation of law by the director, (ii) conduct violating Section 23A.08.450 of
the Washington Business Corporation Act, or (iii) any transaction from which the
director will personally receive a benefit in money, property, or services to
which the director is not legally entitled.  If the Washington Business
Corporation Act is amended to authorize corporate action further eliminating or
limiting the personal liability of directors, then the liability of a director
of the Corporation shall be eliminated or limited to the fullest extent
permitted by the Washington Business Corporation Act, as so amended.  Any repeal
or modification of the foregoing paragraph by the shareholders of the
corporation shall not adversely affect any right or protection of a director of
the Corporation existing at the time of such repeal or modification.

The Corporation has the power to indemnify, and to purchase and maintain
insurance for, its directors, officers, trustees, employees, and other persons
and agents.  Without limiting the generality of the foregoing, the Corporation
shall indemnify its directors against all liability, damages, and costs or
expenses (including attorney's fees) arising from or in connection with service
for employment by, or other affiliation with this Corporation to the maximum
extent and under all circumstances permitted by law.

     8.   The number of directors constituting the initial Board of Directors of
this Corporation is three (3).  The names and addresses of persons who are to
serve as directors until the first annual meeting of stockholders, or until
their successors are elected and qualified are:

          Name                Address

                              Veradale, Washington 99037

     9.   The Board of Directors shall have authority to divide any or all
classes of shares into series and to fix and determine the relative rights and
preferences of the shares of any series so established or established hereby.
All shares of the same class shall be identical except as to the following
relative rights

                                      -21-

and preferences as to which there may be variations between different series:

               and the terms and conditions of redemption.

               shares.

          e.   The terms and conditions, if any, on which shares may be
               converted.

                       ARTICLES VII - PREEMPTIVE RIGHTS

     The shareholders of the Corporation shall be denied preemptive rights.

                       ARTICLE VIII - CUMULATIVE VOTING

     Shareholders of the Corporation shall be denied the right to cumulate their
votes at the election of directors of the Corporation.

                                  ARTICLE IX

     The provisions of Section 6 of Substitute Senate Bill 3580 as enacted by
the 49th Legislature of the State of Washington in the 1985 regular session
shall not apply to this Corporation.

     IN WITNESS WHEREOF, these Articles of Incorporation have been executed in
duplicate.

date requested promptly remit to Agent at Agent's office in New York, New York
the amount of such Lender's new Loan in immediately available funds, and upon
receipt of such funds, unless to its actual knowledge any conditions precedent
to such Loans have been neither met nor waived as provided herein, Agent shall
promptly make such Loans available to Borrower. Unless Agent shall have received
prompt notice from a Lender that such Lender will not make available to Agent
such Lender's new Loan, Agent may in its discretion assume that such Lender has
made such Loan available to Agent in accordance with this section and Agent may
if it chooses, in reliance upon such assumption, make such Loan available to
Borrower. If and to the extent such Lender shall not so make its new Loan
available to Agent, such Lender and Borrower severally agree to pay or repay to
Agent within three days after demand the amount of such Loan together with
interest thereon, for each day from the date such amount was made available to
Borrower until the date such amount is paid or repaid to Agent, with interest at
(i) the Federal Funds Rate, if such Lender is making such payment and (ii) the
interest rate applicable at the time to the other new Loans made on such date,
if Borrower is making such repayment. If neither such Lender nor Borrower pay or
repay to Agent such amount within such three-day period, Agent shall in addition
to such amount be entitled to recover from such Lender and from Borrower, on
demand, interest thereon at the Default Rate applicable to Base Rate Loans,
calculated from the date such amount was made available to Borrower. The failure
of any Lender to make any new Loan to be made by it hereunder shall not relieve
any other Lender of its obligation hereunder, if any, to make its new Loan, but
no Lender shall be responsible for the failure of any other Lender to make any
new Loan to be made by such other Lender.

      Section 2.3. Continuations and Conversions of Existing Loans. Borrower
                   -----------------------------------------------
may make the following elections with respect to Loans already outstanding: to
convert Base Rate Loans to Eurodollar Loans, to convert Eurodollar Loans to Base
Rate Loans on the last day of the Interest Period applicable thereto, and to
continue Eurodollar Loans beyond the expiration of such Interest Period by
designating a new Interest Period to take effect at the time of such expiration.
In making such elections, Borrower may combine existing Loans made pursuant to
separate Borrowings into one new Borrowing or divide existing Loans made
pursuant to one Borrowing into separate new Borrowings, provided that Borrower
may have no more than six Borrowings of Eurodollar Loans outstanding at any
time. To make any such election, Borrower must give to Agent written notice (or
telephonic notice promptly confirmed in writing) of any such Conversion or
Continuation of existing Loans, with a separate notice given for each new
Borrowing. Each such notice constitutes a "Continuation/Conversion Notice"
hereunder and must:

                                      18
<PAGE>

          (a)  specify the existing Loans which are to be Continued or
     Converted;

          (b)  specify (i) the aggregate amount of any Borrowing of Base Rate
     Loans into which such existing Loans are to be continued or converted and
     the date on which such Continuation or Conversion is to occur, or (ii) the
     aggregate amount of any Borrowing of Eurodollar Loans into which such
     existing Loans are to be continued or converted, the date on which such
     Continuation or Conversion is to occur (which shall be the first day of the
     Interest Period which is to apply to such Eurodollar Loans), and the length
     of the applicable Interest Period; and

          (c)  be received by Agent not later than 1:00 p.m., New York, New
     York time, on (i) the day on which any such Continuation or Conversion to
     Base Rate Loans is to occur, or (ii) the third Business Day preceding the
     day on which any such Continuation or Conversion to Eurodollar Loans is to
     occur.

Each such written request or confirmation must be made in the form and substance
of the "Continuation/Conversion Notice" attached hereto as Exhibit C, duly
completed. Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by Borrower as to the matters which are
required to be set out in such written confirmation. Upon receipt of any such
Continuation/Conversion Notice, Agent shall give each Lender prompt notice of
the terms thereof. Each Continuation/Conversion Notice shall be irrevocable and
binding on Borrower. During the continuance of any Default, Borrower may not
make any election to convert existing Loans into Eurodollar Loans or continue
existing Loans as Eurodollar Loans. If (due to the existence of a Default or for
any other reason) Borrower fails to timely and properly give any
Continuation/Conversion Notice with respect to a Borrowing of existing
Eurodollar Loans at least three days prior to the end of the Interest Period
applicable thereto, such Eurodollar Loans shall automatically be converted into
Base Rate Loans at the end of such Interest Period. No new funds shall be repaid
by Borrower or advanced by any Lender in connection with any Continuation or
Conversion of existing Loans pursuant to this section, and no such Continuation
or Conversion shall be deemed to be a new advance of funds for any purpose; such
Continuations and Conversions merely constitute a change in the interest rate
applicable to already outstanding Loans.

      Section 2.4. Use of Proceeds. Borrower shall use the proceeds of all Loans
                   ---------------
to (i) continue the loans and letters of credit outstanding under the Existing
Credit Agreement, (ii) finance development and drilling activities with respect
to Proved Reserves of Borrower, (iii) provide working capital for Borrower's and
Inland Refining's operations, provided that the advances to Inland Refining,
plus Letters of Credit issued for the benefit of Inland Refining, plus any
amounts that have been advanced pursuant to any such Letter of Credit which have
not been reimbursed by Inland Refining to Borrower, shall not in the aggregate
(but without duplication) exceed the amount of $20,000,000 outstanding at any
one time, and (iv) refinance its Matured LC Obligations; provided, however, that
Borrower shall not use any Loans to make advances to Inland Refining, except as
specifically set forth in this Section 2.4. Borrower shall use all Letters of
Credit for its general corporate purposes and to support agreements for the
purchase by Inland Refining of refining feed stocks in the ordinary course of
business. In no event shall the funds

                                      19
<PAGE>

from any Loan or any Letter of Credit be used directly or indirectly by any
Person for personal, family, household or agricultural purposes or for the
purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or
carrying any "margin stock" or any "margin securities" (as such terms are
defined in Regulation U promulgated by the Board of Governors of the Federal
Reserve System) or to extend credit to others directly or indirectly for the
purpose of purchasing or carrying any such margin stock or margin securities.
Borrower represents and warrants that Borrower is not engaged principally, or as
one of Borrower's important activities, in the business of extending credit to
others for the purpose of purchasing or carrying such margin stock or margin
securities.

      Section 2.5. Interest Rates and Fees.
                   -----------------------

      (a)  Interest Rates. Each Base Rate Loan shall bear interest on each day
           -------------
outstanding at the Adjusted Base Rate in effect on such day. Each Eurodollar
loan shall bear interest on each day during the related Interest Period at the
related Adjusted Eurodollar Rate in effect on such day. Anything to the contrary
herein notwithstanding, if an Event of Default has occurred and is continuing,
all Loans shall bear interest on each day outstanding at the applicable Default
Rate. Past due payments of principal and interest shall bear interest at the
rates and in the manner set forth in the Notes.

      (b)  Commitment Fees. In consideration of each Lender's commitment to make
           ---------------
Loans, Borrower will pay to Agent for the account of each Lender a commitment
fee determined on a daily basis by applying a rate of one-half of one percent
(0.5%) per annum to such Lender's Percentage Share of the unused portion of the
Borrowing Base on each day until the Maturity Date, determined for each such day
by deducting from the amount of the Borrowing Base at the end of such day the
sum of (i) the Facility Usage and (ii) the amount of all LC Obligations
outstanding at the end of such day. This commitment fee shall be due and payable
in arrears on the last Business Day after the end of each Fiscal Quarter and on
the Maturity Date.

      (c)  Facility Fees. In consideration of each Lender's commitment to make
           -------------
Loans, Borrower will pay to Agent for the pro rata distribution to each Lender
in accordance with such Lender's Percentage Share, a facility fee in the
aggregate amount of $150,000, due and payable on the Effective Date. In addition
to the facility fee described in the immediately preceding sentence of this
Section 2.5(c), Borrower shall pay to Agent for the pro rata distribution to
each Lender in accordance with such Lender's Percentage Share (i) a facility fee
equal to one-half of the percent (0.50%) of such Lender's Percentage Share of
the Borrowing Base on March 31, 2001 due and payable on April 1, 2001, and (ii)
a facility fee equal to one-half of one percent (0.50%) of such Lender's
Percentage Share of the Borrowing Base on September 30, 2001 due and payable on
October 1, 2001. In addition to the foregoing, on the date hereof, Borrower will
pay to Agent for the distribution to each Lender based upon its outstanding
loans to Borrower from July 1, 1999 to the Effective Date a fee in the amount of
$208,322.92. In addition to the fees described above, Borrower will pay to Agent
for the pro rata distribution to each Lender in accordance with such Lender's
Percentage Share, a fee equal to one percent (1.00%) of such Lender's Percentage
Share of the Borrowing Base on September 30, 2000 due and payable on October 1,
2000; provided, however, the fee provided for in this sentence shall not be
payable to

                                      20
<PAGE>

any Lender if prior to September 30, 2000 Borrower has caused one or more
substitute financial institutions reasonably acceptable to the Lenders, to
purchase the full amount of the Loans made by ING (U.S.) Capital Corporation
("ING"), at par, plus all accrued unpaid interest, fees, and all other accrued
Obligations owing to ING, and assume all obligations and commitments of ING
hereunder.

      (d)  Agent's Fee. In addition to all other amounts due to Agent under the
           -----------
Loan Documents, Borrower will pay fees to Agent, for its own account, as
described in that certain letter agreement executed in connection with the
Existing Credit Agreement between Agent and Borrower.

      Section 2.6. Optional Prepayments. Borrower may, upon five Business Days'
                   --------------------
notice to each Lender, from time to time and without premium or penalty prepay
the Notes, in whole or in part, so long as the aggregate amounts of all partial
prepayments of principal on the Notes equals $1,000,000 or any higher integral
multiple of $1,000,000, so long as Borrower does not prepay any Eurodollar Loan,
and so long as Borrower does not make any prepayments which would reduce the
unpaid principal balance of any Loan to less than $100,000 without first either
(a) terminating this Agreement or (b) providing assurance satisfactory to Agent
in its discretion that Lenders' legal rights under the Loan Documents are in no
way affected by such reduction. Each prepayment of principal under this section
shall be accompanied by all interest then accrued and unpaid on the principal so
prepaid. Any principal or interest prepaid pursuant to this section shall be in
addition to, and not in lieu of, all payments otherwise required to be paid
under the Loan Documents at the time of such prepayment.

      Section 2.7. Mandatory Prepayments.
                   ---------------------

      (a)  If at any time the Facility Usage exceeds the Maximum Credit Amount,
Borrower shall immediately upon demand prepay the principal of the Loans in an
amount equal to such excess.

      (b)  If at any time the Facility Usage is less than the Maximum Credit
Amount but is in excess of the Borrowing Base (such excess being herein called a
"Borrowing Base Deficiency"), Borrower shall, within five Business Days after
Agent gives notice of such fact to Borrower, either:

              (i)  prepay the principal of the Loans in an aggregate amount at
     least equal to such Borrowing Base Deficiency, or

              (ii) give notice to Agent electing to prepay the principal of the
     Loans in up to three monthly installments in an aggregate amount at least
     equal to such Borrowing Base Deficiency, with each such installment equal
     to or in excess of one-third of such Borrowing Base Deficiency, and with
     the first such installment to be paid one month after the giving of such
     notice and the subsequent installments to be due and payable at one month
     intervals thereafter until such Borrowing Base Deficiency has been
     eliminated, or

                                      21
<PAGE>

              (iii)  give notice to Agent that Borrower desires to provide Agent
     with deeds of trust, mortgages, chattel mortgages, security agreements,
     financing statements and other security documents in form and substance
     satisfactory to Agent, granting, confirming, and perfecting first and prior
     liens or security interests in collateral acceptable to all Lenders, to the
     extent needed to allow all Lenders to increase the Borrowing Base (as they
     in their reasonable discretion deem consistent with prudent oil and gas
     banking industry lending standards at the time) to an amount which
     eliminates such Borrowing Base Deficiency, and then provide such security
     documents within thirty days after Agent specifies such collateral to
     Borrower. If, prior to any such specification by Agent, Required Lenders
     determine that the giving of such security documents will not serve to
     eliminate such Borrowing Base Deficiency, then, within five Business Days
     after receiving notice of such determination, Borrower will elect to make,
     and thereafter make, the prepayments specified in either of the preceding
     subsections (i) or (ii) of this subsection (b).

     (c)  Each prepayment of principal under this section shall be accompanied
by all interest then accrued and unpaid on the principal so prepaid. Any
principal or interest prepaid pursuant to this section shall be in addition to,
and not in lieu of, all payments otherwise required to be paid under the Loan
Documents at the time of such prepayment.

     Section 2.8. Initial Borrowing Base. During the period from the Effective
                  ----------------------
Date to the first Determination Date the Borrowing Base shall be $83,500,000.

     Section 2.9. Subsequent Determinations of Borrowing Base; Reduction of
                   ---------------------------------------------------------
Borrowing Base.
- --------------

     (a)  By October 1 and April 1 of each year, beginning October 1, 2000,
dated no earlier than the preceding August 1 and February 1, respectively,
Borrower shall furnish to each Lender all information, reports and data which
Agent has then requested concerning Restricted Persons' businesses and
properties (including their oil and gas properties and interests and the
reserves and production relating thereto), together with the Engineering Report
described in Section 6.2(d). By the Optional Redetermination Date prepared as of
the sixtieth day before such Optional Redetermination Date, Borrower shall
furnish to each Lender all information, reports and data which Agent has then
requested concerning Restricted Persons' businesses and properties (including
their oil and gas properties and interests and the reserves and production
relating thereto), together with the Engineering Report described in Section
6.2(e). Within thirty days after receiving such information, reports and data,
Required Lenders shall agree upon an amount for the Borrowing Base (provided
that all Lenders must agree to any increase in the Borrowing Base) and Agent
shall by notice to Borrower designate such amount as the new Borrowing Base
available to
Borrower hereunder, which designation shall take effect immediately on the date
such notice is sent (herein called a "Determination Date") and shall remain in
                                      ------------------
effect until but not including the next date as of which the Borrowing Base is
redetermined.  If Borrower does not furnish all such information, reports and
data by the date specified in the first sentence of this section, Agent may
nonetheless designate the Borrowing Base at any amount which Required Lenders
determine and may redesignate the Borrowing Base

                                      22
<PAGE>

from time to time thereafter until each Lender receives all such information,
reports and data, whereupon Required Lenders shall designate a new Borrowing
Base as described above. Required Lenders shall determine the amount of the
Borrowing Base based upon the loan collateral value which they in their
discretion assign to the various proved oil and gas properties of Restricted
Persons at the time in question and based upon such other credit factors
(including without limitation the assets, liabilities, cash flow, hedged and
unhedged exposure to price, foreign exchange rate, and interest rate changes,
business, properties, prospects, management and ownership of Borrower and its
Affiliates) as they in their discretion deem significant. It is expressly
understood that Lenders and Agent have no obligation to agree upon or designate
the Borrowing Base at any particular amount, whether in relation to the
aggregate face amount of the Notes or otherwise, and that Lenders' commitments
to advance funds hereunder is determined by reference to the Borrowing Base from
time to time in effect, which Borrowing Base shall be used for calculating
commitment fees under Section 2.5 and, to the extent permitted by Law and
regulatory authorities, for the purposes of capital adequacy determination and
reimbursements under Section 3.2.

     (b)  Until the Maturity Date, Borrower may at any time by notice to Agent
reduce the Borrowing Base then in effect to any lesser amount. Each such notice
shall take effect on the date specified therein, which may not be earlier than
the date on which such notice is received by Agent, and shall continue in effect
until the next date as of which the Borrowing Base is redetermined.

     (c)  The Borrowing Base shall be reduced in an amount equal to any
prepayment on the Loans made in accordance with Section 7.4. Each such reduction
shall take effect on the date of such prepayment, and shall continue in effect
until the next date as of which the Borrowing Base is redetermined.

     Section 2.10. Letters of Credit. Subject to the terms and conditions
                   -----------------
hereof, Borrower may until the Maturity Date request either LC Issuer to issue
one or more Letters of Credit, provided that, after taking such Letter of Credit
into account:

          (a)  the Facility Usage does not exceed the Borrowing Base at such
     time; and

          (b)  the aggregate amount of LC Obligations at such time does not
     exceed $4,000,000; and

          (c)  the expiration date of such Letter of Credit is prior to the
     Maturity Date.

     and further provided that:

          (d)  such Letter of Credit is to be used to support either (i)
     agreements for the purchase by Inland Refining of refinery feed stocks in
     the ordinary course of business and has an expiration date not more than
     seventy (70) days from the date of issuance or (ii) up to the aggregate
     amount of $400,000, the payment of diesel fuel and motor fuel taxes

                                      23
<PAGE>

     payable to the State of Utah and has an expiration date not more than three
     hundred sixty-five (365) days from the date of issuance;

          (e)  such Letter of Credit is not directly or indirectly used to
     assure payment of or otherwise support any Restricted Debt of any Person;

          (f)  the issuance of such Letter of Credit will be in compliance with
     all applicable governmental restrictions, policies, and guidelines and will
     not subject LC Issuer to any cost which is not reimbursable under Article
     III;

          (g)  the form and terms of such Letter of Credit are acceptable to
     such LC Issuer in its sole and absolute discretion; and

          (h)  all other conditions in this Agreement to the issuance of such
     Letter of Credit have been satisfied.

     LC Issuer will honor any such request if the foregoing conditions (a)
     through (h) (in the following Section 2.11 called the "LC Conditions") have
                                                            -------------
     been met as of the date of issuance of such Letter of Credit.  LC Issuer
     may choose to honor any such request for any other Letter of Credit but has
     no obligation to do so and may refuse to issue any other requested Letter
     of Credit for any reason which such LC Issuer in its sole discretion deems
     relevant.

     Section 2.11. Requesting Letters of Credit. Borrower must make written
                   ----------------------------
application for any Letter of Credit at least three Business Days before the
date on which Borrower desires such Letter of Credit to be issued, by delivering
such application to Agent. Agent shall promptly deliver such application to LC
Issuer. By making any such written application Borrower shall be deemed to have
represented and warranted to each Lender or LC Issuer that the LC Conditions
described in Section 2.10 will be met as of the date of issuance of such Letter
of Credit. Each such written application for a Letter of Credit must be made in
writing in the form and substance of Exhibit G, the terms and provisions of
which are hereby incorporated herein by reference (or in such other form as may
mutually be agreed upon by Agent, LC Issuer and Borrower). Two Business Days
after the LC Conditions for a Letter of Credit have been met as described in
Section 2.10 (or if an LC Issuer otherwise desires to issue such Letter of
Credit), LC Issuer will issue such Letter of Credit at LC Issuer's office, and
will provide Agent with a specimen copy of the Letter of Credit so issued. If
any provisions of any LC Application conflict with any provisions of this
Agreement, the provisions of this Agreement shall govern and control.

     Section 2.12. Reimbursement and Participations.
                   --------------------------------

          (a)  Reimbursement by Borrower. Each Matured LC Obligation shall
               -------------------------
     constitute a loan by LC Issuer to Borrower. Borrower promises to pay to LC
     Issuer, or to LC Issuer's order, on demand, the full amount of each Matured
     LC Obligation, together with interest thereon at the Default Rate
     applicable to Base Rate Loans.

                                      24
<PAGE>

          (b)  Letter of Credit Advances. If the beneficiary of any Letter of
               -------------------------
     Credit makes a draft or other demand for payment thereunder then Borrower
     may, during the interval between the making thereof and the honoring
     thereof by LC Issuer, request Lenders to make Loans to Borrower in the
     amount of such draft or demand, which Loans shall be made concurrently with
     LC Issuer's payment of such draft or demand and shall be immediately used
     by LC Issuer to repay the amount of the resulting Matured LC Obligation.
     Such a request by Borrower shall be made in compliance with all of the
     provisions hereof, provided that for the purposes of the first sentence of
     Section 2.1 the amount of such Loans shall be considered but the amount of
     the Matured LC Obligation to be concurrently paid by such Loans shall not
     be considered.

          (c)  Participation by Lenders. Each LC Issuer irrevocably agrees to
               ------------------------
     grant and hereby grants to each Lender, and -- to induce each LC Issuer to
     issue Letters of Credit hereunder -- each Lender irrevocably agrees to
     accept and purchase and hereby accepts and purchases from such LC Issuer,
     on the terms and conditions hereinafter stated and for such Lender's own
     account and risk, an undivided interest equal to such Lender's Percentage
     Share of such LC Issuer's obligations and rights under each Letter of
     Credit issued hereunder by such LC Issuer and the amount of each Matured LC
     Obligation paid by such LC Issuer thereunder. Each Lender unconditionally
     and irrevocably agrees with LC Issuer that, if a Matured LC Obligation is
     paid under any Letter of Credit for which such LC Issuer is not reimbursed
     in full by Borrower in accordance with the terms of this Agreement and the
     related LC Application (including any reimbursement by means of concurrent
     Loans or by the application of LC Collateral), such Lender shall (in all
     circumstances and without set-off or counterclaim) pay to such LC Issuer on
     demand, in immediately available funds at such LC Issuer's address for
     notices hereunder, such Lender's Percentage Share of such Matured LC
     Obligation (or any portion thereof which has not been reimbursed by
     Borrower). Each Lender's obligation to pay an LC Issuer pursuant to the
     terms of this subsection is irrevocable and unconditional. If any amount
     required to be paid by any Lender to an LC Issuer pursuant to this
     subsection is paid by such Lender to an LC Issuer within three Business
     Days after the date such payment is due, LC Issuer shall in addition to
     such amount be entitled to recover from such Lender, on demand, interest
     thereon calculated from such due date at the Federal Funds Rate. If any
     amount required to be paid by any Lender to LC Issuer pursuant to this
     subsection is not paid by such Lender to LC Issuer within three Business
     Days after the date such payment is due, LC Issuer shall in addition to
     such amount be entitled to recover from such Lender, on demand, interest
     thereon calculated from such due date at the Default Rate applicable to
     Base Rate Loans.

          (d)  Distributions to Participants. Whenever an LC Issuer has in
               -----------------------------
     accordance with this section received from any Lender payment of such
     Lender's Percentage Share of any Matured LC Obligation, if such LC Issuer
     thereafter receives any payment of such Matured LC Obligation or any
     payment of interest thereon (whether directly from Borrower or by
     application of LC Collateral or otherwise, and excluding only interest for
     any period prior to such LC Issuer's demand that such Lender make such
     payment of its Percentage Share), such LC Issuer will distribute to such
     Lender its Percentage Share of

                                      25
<PAGE>

     the amounts so received by such LC Issuer; provided, however, that if any
                                                --------  -------
     such payment received by an LC Issuer must thereafter be returned by such
     LC Issuer, such Lender shall return to such LC Issuer the portion thereof
     which such LC Issuer has previously distributed to it.

          (e)  Calculations. A written advice setting forth in reasonable
               ------------
     detail the amounts owing under this section, submitted by an LC Issuer to
     Borrower or any Lender from time to time, shall be conclusive, absent
     manifest error, as to the amounts thereof.

     Section 2.13. Letter of Credit Fees.  In consideration of LC Issuer's
                   ---------------------
issuance of any Letter of Credit, Borrower agrees to pay (a) to Agent, for the
account of all Lenders in accordance with their respective Percentage Shares, a
letter of credit fee at a rate equal to two percent (2.00%) per annum of the
amount of all Letters of Credit, and (b) to a LC Issuer for its own account, a
letter of credit fronting fee at a rate equal to fifteen one-hundredths of one
percent (0.15%) per annum of each Letter of Credit issued by such LC Issuer.
Each such fee will be calculated on a daily basis, on the face amount of Letters
of Credit outstanding on each day at the above applicable rate and will be
payable quarterly in arrears. In addition, Borrower will pay to an LC Issuer a
minimum administrative issuance fee of $200 for each Letter of Credit issued by
such LC Issuer and an amendment fee of $65 for each Letter of Credit, each such
fee to be payable upon issuance or amendment, respectively, of a Letter of
Credit.

      Section 2.14. No Duty to Inquire.
                    ------------------

          (a)  Drafts and Demands. LC Issuer is authorized and instructed to
               ------------------
     accept and pay drafts and demands for payment under any Letter of Credit
     without requiring, and without responsibility for, any determination as to
     the existence of any event giving rise to said draft, either at the time of
     acceptance or payment or thereafter. LC Issuer is under no duty to
     determine the proper identity of anyone presenting such a draft or making
     such a demand (whether by tested telex or otherwise) as the officer,
     representative or agent of any beneficiary under any Letter of Credit, and
     payment by LC Issuer to any such beneficiary when requested by any such
     purported officer, representative or agent is hereby authorized and
     approved. Borrower agrees to hold LC Issuer and each other Lender Party
     harmless and indemnified against any liability or claim in connection with
     or arising out of the subject matter of this section, WHICH INDEMNITY SHALL
     APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY
     EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY
     KIND BY ANY LENDER PARTY, provided only that no Lender Party shall be
     entitled to indemnification for that portion, if any, of any liability or
     claim which is proximately caused by its own individual gross negligence or
     willful misconduct, as determined in a final judgment.

          (b)  Extension of Maturity. If the maturity of any Letter of Credit
               ---------------------
     is extended by its terms or by Law or governmental action, if any extension
     of the maturity or time for presentation of drafts or any other
     modification of the terms of any Letter of Credit is

                                      26

<PAGE>

     made at the request of any Restricted Person, or if the amount of any
     Letter of Credit is increased at the request of any Restricted Person, this
     Agreement shall be binding upon all Restricted Persons with respect to such
     Letter of Credit as so extended, increased or otherwise modified, with
     respect to drafts and property covered thereby, and with respect to any
     action taken by LC Issuer, LC Issuer's correspondents, or any Lender Party
     in accordance with such extension, increase or other modification.

          (c)  Transferees of Letters of Credit. If any Letter of Credit
               --------------------------------
     provides that it is transferable, LC Issuer shall have no duty to determine
     the proper identity of anyone appearing as transferee of such Letter of
     Credit, nor shall LC Issuer be charged with responsibility of any nature or
     character for the validity or correctness of any transfer or successive
     transfers, and payment by LC Issuer to any purported transferee or
     transferees as determined by LC Issuer is hereby authorized and approved,
     and Borrower further agrees to hold LC Issuer and each other Lender Party
     harmless and indemnified against any liability or claim in connection with
     or arising out of the foregoing, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT
     ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE
     OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER
     PARTY, provided only that no Lender Party shall be entitled to
     indemnification for that portion, if any, of any liability or claim which
     is proximately caused by its own individual gross negligence or willful
     misconduct, as determined in a final judgment.

     Section 2.15. LC Collateral.
                   -------------

          (a)  LC Obligations in Excess of Borrowing Base. If, after the making
               ------------------------------------------
     of all mandatory prepayments required under Section 2.7, the outstanding LC
     Obligations will exceed the Borrowing Base, then in addition to prepayment
     of the Borrowing Base Deficiency Borrower will immediately pay to LC Issuer
     an amount equal to such excess. LC Issuer will hold such amount as security
     for the remaining LC Obligations (all such amounts held as security for LC
     Obligations being herein collectively called "LC Collateral") until such LC
                                                   -------------
     Obligations become Matured LC Obligations, at which time such LC Collateral
     may be applied to such Matured LC Obligations. Neither this subsection nor
     the following subsection shall, however, limit or impair any rights which
     LC Issuer may have under any other document or agreement relating to any
     Letter of Credit or LC Obligation, including any LC Application, or any
     rights which any Lender Party may have to otherwise apply any payments by
     Borrower and any LC Collateral under Section 3.1.

          (b)  Acceleration of LC Obligations. If the Obligations or any part
               ------------------------------
     thereof become immediately due and payable pursuant to Section 8.2 then,
     unless Required Lenders otherwise specifically elect to the contrary (which
     election may thereafter be retracted by Required Lenders at any time), all
     LC Obligations shall become immediately due and payable without regard to
     whether or not actual drawings or payments on the

                                      27
<PAGE>

     Letters of Credit have occurred, and Borrower shall be obligated to pay to
     LC Issuer immediately an amount equal to the aggregate LC Obligations which
     are then outstanding. All amounts so paid shall first be applied to Matured
     LC Obligations and then held by LC Issuer as LC Collateral until such LC
     Obligations become Matured LC Obligations, at which time such LC Collateral
     shall be applied to such Matured LC Obligations.

          (c)  Investment of LC Collateral. Pending application thereof, all LC
               ---------------------------
     Collateral shall be invested by LC Issuer in such investments as LC Issuer
     may choose in its sole discretion. All interest on such investments shall
     be reinvested or applied to Matured LC Obligations. When all Obligations
     have been satisfied in full, including all LC Obligations, all Letters of
     Credit have expired or been terminated, and all of Borrower's reimbursement
     obligations in connection therewith have been satisfied in full, LC Issuer
     shall release any remaining LC Collateral. Borrower hereby assigns and
     grants to LC Issuer a continuing security interest in all LC Collateral
     paid by it to LC Issuer, all investments purchased with such LC Collateral,
     and all proceeds thereof to secure its Matured LC Obligations and its
     Obligations under this Agreement, each Note, and the other Loan Documents,
     and Borrower agrees that such LC Collateral and investments and proceeds
     shall be subject to all of the terms and conditions of the Security
     Documents. Borrower further agrees that LC Issuer shall have all of the
     rights and remedies of a secured party under the Uniform Commercial Code as
     adopted in the State of New York with respect to such security interest and
     that an Event of Default under this Agreement shall constitute a default
     for purposes of such security interest.

          (d)  Payment of LC Collateral. When Borrower is required to provide
               ------------------------
     LC Collateral for any reason and fails to do so on the day when required,
     LC Issuer may without notice to Borrower or any other Restricted Person
     provide such LC Collateral (whether by application of proceeds of other
     Collateral, by transfers from other accounts maintained with LC Issuer, or
     otherwise) using any available funds of Borrower or any other Person also
     liable to make such payments. Any such amounts which are required to be
     provided as LC Collateral and which are not provided on the date required
     shall, for purposes of each Security Document, be considered past due
     Obligations owing hereunder, and LC Issuer is hereby authorized to exercise
     its respective rights under each Security Document to obtain such amounts.


                       ARTICLE III - Payments to Lenders
                                     -------------------

     Section 3.1. General Procedures. Borrower will make each payment which it
                  ------------------
owes under the Loan Documents to Agent for the account of the Lender Party to
whom such payment is owed, in lawful money of the United States of America,
without set-off, deduction or counterclaim, and in immediately available funds.
Each such payment must be received by Agent not later than 11:00 a.m., New York,
New York time, on the date such payment becomes due and payable. Any payment
received by Agent after such time will be deemed to have been made on the next
following Business Day. Should any such payment become due and payable

                                      28
<PAGE>

on a day other than a Business Day, the maturity of such payment shall be
extended to the next succeeding Business Day, and, in the case of a payment of
principal or past due interest, interest shall accrue and be payable thereon for
the period of such extension as provided in the Loan Document under which such
payment is due. Each payment under a Loan Document shall be due and payable at
the place provided therein and, if no specific place of payment is provided,
shall be due and payable at the place of payment of Agent's Note. When Agent
collects or receives money on account of the Obligations, Agent shall distribute
all money so collected or received, and each Lender Party shall apply all such
money so distributed, as follows:

          (a)  first, for the payment of all Obligations which are then due (and
     if such money is insufficient to pay all such Obligations, first to any
     reimbursements due Agent under Section 6.9 or 10.4 and then to the partial
     payment of all other Obligations then due in proportion to the amounts
     thereof, or as Lender Parties shall otherwise agree);

          (b)  then for the prepayment of amounts owing under the Loan Documents
     (other than principal on the Notes) if so specified by Borrower;

          (c)  then for the prepayment of principal on the Notes, together with
     accrued and unpaid interest on the principal so prepaid; and

          (d)  last, for the payment or prepayment of any other Obligations.

All payments applied to principal or interest on any Note shall be applied first
to any interest then due and payable, then to principal then due and payable,
and last to any prepayment of principal and interest in compliance with Sections
2.6 and 2.7. All distributions of amounts described in any of subsections (b),
(c), or (d) above shall be made by Agent pro rata to Agent and each Lender Party
then owed Obligations described in such subsection in proportion to all amounts
owed all Lender Parties which are described in such subsection; provided that if
any Lender then owes payments to Agent for the purchase of a participation under
Section 2.12(c) hereof, any amounts otherwise distributable under this section
to such Lender shall be deemed to belong to LC Issuer, or Agent, respectively,
to the extent of such unpaid payments, and Agent shall apply such amounts to
make such unpaid payments rather than distribute such amounts to such Lender.

     Section 3.2. Capital Reimbursement. If either (a) the introduction or
                  ---------------------
implementation of or the compliance with or any change in or in the
interpretation of any Law, or (b) the introduction or implementation of or the
compliance with any request, directive or guideline from any central bank or
other governmental authority (whether or not having the force of Law) affects or
would affect the amount of capital required or expected to be maintained by any
Lender Party or any corporation controlling any Lender Party, then, upon demand
by such Lender Party, Borrower will pay to Agent for the benefit of such Lender
Party, from time to time as specified by such Lender Party, such additional
amount or amounts which such Lender Party shall determine to be appropriate to
compensate such Lender Party or any corporation controlling such Lender Party in
light of such circumstances, to the extent that such Lender Party reasonably
determines that the amount of any such capital would be increased or the rate of
return on any

                                      29
<PAGE>

such capital would be reduced by or in whole or in part based on the existence
of the face amount of such Lender's Loans, commitments, or the provisions
concerning the issuance of Letters of Credit under this Agreement.

     Section 3.3. Increased Cost of Eurodollar Loans or Letters of Credit. If
                  -------------------------------------------------------
any applicable Law (whether now in effect or hereinafter enacted or promulgated,
including Regulation D) or any interpretation or administration thereof by any
governmental authority charged with the interpretation or administration thereof
(whether or not having the force of Law):

          (a) shall change the basis of taxation of payments to any Lender Party
     of any principal, interest, or other amounts attributable to any Eurodollar
     Loan or otherwise due under this Agreement in respect of any Eurodollar
     Loan or Letter of Credit (other than taxes imposed on the overall net
     income of such Lender Party or any lending office of such Lender Party by
     any jurisdiction in which such Lender Party or any such lending office is
     located); or

          (b) shall change, impose, modify, apply or deem applicable any
     reserve, special deposit or similar requirements in respect of any
     Eurodollar Loan or Letter of Credit (excluding those for which such Lender
     Party is fully compensated pursuant to adjustments made in the definition
     of Eurodollar Rate) or against assets of, deposits with or for the account
     of, or credit extended by, such Lender Party; or

          (c) shall impose on any Lender Party or the interbank eurocurrency
     deposit market any other condition affecting any Eurodollar Loan or Letter
     of Credit, the result of which is to increase the cost to any Lender Party
     of funding or maintaining any Eurodollar Loan or of issuing any Letter of
     Credit or to reduce the amount of any sum receivable by any Lender Party in
     respect of any Eurodollar Loan or Letter of Credit by an amount deemed by
     such Lender Party to be material,

     then such Lender Party shall promptly notify Agent and Borrower in writing
     of the happening of such event and of the amount required to compensate
     such Lender Party for such event (on an after-tax basis, taking into
     account any taxes on such compensation), whereupon (i) Borrower shall pay
     such amount to Agent for the account of such Lender Party and (ii) Borrower
     may elect, by giving to Agent and such Lender Party not less than three
     Business Days' notice, to convert all (but not less than all) of any such
     Eurodollar Loans into Base Rate Loans.

     Section 3.4. Availability. If (a) any change in applicable Laws, or in the
                  ------------
interpretation or administration thereof of or in any jurisdiction whatsoever,
domestic or foreign, shall make it unlawful or impracticable for any Lender
Party to fund or maintain Eurodollar Loans, or shall materially restrict the
authority of any Lender Party to purchase or take offshore deposits of dollars
(i.e., "eurodollars") or to issue Letters of Credit, (b) any Lender Party
determines that matching deposits appropriate to fund or maintain any Eurodollar
Loan are not available to it, or (c) any Lender Party determines that the
formula for calculating the Eurodollar Rate does not fairly reflect the cost to
such Lender Party of making or maintaining loans based on such rate,

                                      30
<PAGE>

then, upon notice by such Lender Party to Borrower and Agent, Borrower's right
to elect Eurodollar Loans or to apply for Letters of Credit from such Lender
Party shall be suspended to the extent and for the duration of such illegality,
impracticability or restriction and all Eurodollar Loans of such Lender Party
which are then outstanding or are then the subject of any Borrowing Notice and
which cannot lawfully or practicably be maintained or funded shall immediately
become or remain, or shall be funded as, Base Rate Loans of such Lender Party.
Borrower agrees to indemnify each Lender Party and hold it harmless against all
costs, expenses, claims, penalties, liabilities and damages which may result
from any such change in Law, interpretation or administration (other than taxes
imposed on the overall net income of such Lender Party or any lending office of
such Lender Party). Such indemnification shall be on an after-tax basis, taking
into account any taxes imposed on the amounts paid as indemnity.

     Section 3.5. Funding Losses. In addition to its other obligations
                  --------------
hereunder, Borrower will indemnify each Lender Party against, and reimburse each
Lender Party on demand for, any loss or expense incurred or sustained by such
Lender Party (including any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by a Lender
Party to fund or maintain Eurodollar Loans), as a result of (a) any payment or
prepayment (whether authorized or required hereunder or otherwise) of all or a
portion of a Eurodollar Loan on a day other than the day on which the applicable
Interest Period ends, (b) any payment or prepayment, whether required hereunder
or otherwise, of a Loan made after the delivery, but before the effective date,
of a Continuation/Conversion Notice, if such payment or prepayment prevents such
Continuation/Conversion Notice from becoming fully effective, (c) the failure of
any Loan to be made or of any Continuation/Conversion Notice to become effective
due to any condition precedent not being satisfied or due to any other action or
inaction of any Restricted Person, or (d) any Conversion (whether authorized or
required hereunder or otherwise) of all or any portion of any Eurodollar Loan
into a Base Rate Loan or into a different Eurodollar Loan on a day other than
the day on which the applicable Interest Period ends.  Such indemnification
shall be on an after-tax basis, taking into account any taxes imposed on the
amounts paid as indemnity.

     Section 3.6. Reimbursable Taxes.  Borrower covenants and agrees that:
                  ------------------

          (a)  Borrower will indemnify each Lender Party against and reimburse
     each Lender Party for all present and future income, stamp and other taxes,
     levies, costs and charges whatsoever imposed, assessed, levied or collected
     on or in respect of this Agreement or any Eurodollar Loans or Letters of
     Credit (whether or not legally or correctly imposed, assessed, levied or
     collected), excluding, however, any taxes imposed on or measured by the
     overall net income of Agent or such Lender Party or any lending office of
     such Lender Party by any jurisdiction in which such Lender Party or any
     such lending office is located (all such non-excluded taxes, levies, costs
     and charges being collectively called 'Reimbursable Taxes' in this
     section). Such indemnification shall be on an after-tax basis, taking into
     account any taxes imposed on the amounts paid as indemnity.

                                      31
<PAGE>

          (b)  All payments on account of the principal of, and interest on,
     each Lender Party's Loans and Note, and all other amounts payable by
     Borrower to any Lender Party hereunder, shall be made in full without
     set-off or counterclaim and shall be made free and clear of and without
     deductions or withholdings of any nature by reason of any Reimbursable
     Taxes, all of which will be for the account of Borrower. In the event of
     Borrower being compelled by Law to make any such deduction or withholding
     from any payment to any Lender Party, Borrower shall pay on the due date of
     such payment, by way of additional interest, such additional amounts as are
     needed to cause the amount receivable by such Lender Party after such
     deduction or withholding to equal the amount which would have been
     receivable in the absence of such deduction or withholding. If Borrower
     should make any deduction or withholding as aforesaid, Borrower shall
     within 60 days thereafter forward to such Lender Party an official receipt
     or other official document evidencing payment of such deduction or
     withholding.

          (c)  If Borrower is ever required to pay any Reimbursable Tax with
     respect to any Eurodollar Loan, Borrower may elect, by giving to Agent and
     such Lender Party not less than three Business Days' notice, to convert all
     (but not less than all) of any such Eurodollar Loan into a Base Rate Loan,
     but such election shall not diminish Borrower's obligation to pay all
     Reimbursable Taxes.

          (d)  Notwithstanding the foregoing provisions of this section,
     Borrower shall be entitled, to the extent it is required to do so by Law,
     to deduct or withhold (and not to make any indemnification or reimbursement
     for) income or other similar taxes imposed by the United States of America
     (other than any portion thereof attributable to a change in federal income
     tax Laws effected after the date hereof) from interest, fees or other
     amounts payable hereunder for the account of any Lender Party, other than a
     Lender Party (i) who is a U.S. person for Federal income tax purposes or
     (ii) who has the Prescribed Forms on file with Agent (with copies provided
     to Borrower) for the applicable year to the extent deduction or withholding
     of such taxes is not required as a result of the filing of such Prescribed
     Forms, provided that if Borrower shall so deduct or withhold any such
     taxes, it shall provide a statement to Agent and such Lender Party, setting
     forth the amount of such taxes so deducted or withheld, the applicable rate
     and any other information or documentation which such Lender Party may
     reasonably request for assisting such Lender Party to obtain any allowable
     credits or deductions for the taxes so deducted or withheld in the
     jurisdiction or jurisdictions in which such Lender Party is subject to tax.
     As used in this section, "Prescribed Forms" means such duly executed forms
     or statements, and in such number of copies, which may, from time to time,
     be prescribed by Law and which, pursuant to applicable provisions of (x) an
     income tax treaty between the United States and the country of residence of
     the Lender Party providing the forms or statements, or (y) the Internal
     Revenue Code, permit Borrower to make payments hereunder for the account of
     such Lender Party free of such deduction or withholding of income or
     similar taxes.

     Section 3.7. Change of Applicable Lending Office. Each Lender Party
                  -----------------------------------
agrees that, upon the occurrence of any event giving rise to the operation of
Sections 3.2 through 3.6 with respect

                                      32
<PAGE>

to such Lender Party, it will, if requested by Borrower, use reasonable efforts
(subject to overall policy considerations of such Lender Party) to designate
another Applicable Lending Office, provided that such designation is made on
such terms that such Lender Party and its Lending Office suffer no economic,
legal or regulatory disadvantage, with the object of avoiding the consequence of
the event giving rise to the operation of any such section. Nothing in this
section shall affect or postpone any of the obligations of Borrower or the
rights of any Lender Party provided in Sections 3.2 through 3.6.

     Section 3.8. Replacement of Lenders. If any Lender Party seeks
                  ----------------------
reimbursement for increased costs under Sections 3.2 through 3.6, then within
ninety days thereafter -- provided no Event of Default then exists -- Borrower
shall have the right (unless such Lender Party withdraws its request for
additional compensation) to replace such Lender Party by requiring such Lender
Party to assign its Loans and Notes and its commitments hereunder to an Eligible
Transferee reasonably acceptable to Agent and to Borrower, provided that: (a)
all Obligations of Borrower owing to such Lender Party being replaced (including
such increased costs, but excluding principal and accrued interest on the Notes
being assigned) shall be paid in full to such Lender Party concurrently with
such assignment, and (b) the replacement Eligible Transferee shall purchase the
Note being assigned by paying to such Lender Party a price equal to the
principal amount thereof plus accrued and unpaid interest thereon. In connection
with any such assignment Borrower, Agent, such Lender Party and the replacement
Eligible Transferee shall otherwise comply with Section 10.5. Notwithstanding
the foregoing rights of Borrower under this section, however, Borrower may not
replace any Lender Party which seeks reimbursement for increased costs under
Section 3.2 through 3.6 unless Borrower is at the same time replacing all Lender
Parties which are then seeking such compensation.

                  ARTICLE V - Representations and Warranties
                              ------------------------------

     To confirm each Lender's understanding concerning Restricted Persons and
Restricted Persons' businesses, properties and obligations and to induce each
Lender to enter into this Agreement and to extend credit hereunder, Borrower and
Parent each represent and warrant to each Lender that each of the following
statements is true and correct in all respects.

     Section 5.1. No Default.  No Restricted Person is in default in the
                  ----------
performance of any of the covenants and agreements contained in any Loan
Document. No event has occurred and is continuing which constitutes a Default.

     Section 5.2. Organization and Good Standing. Each Restricted Person is
                  ------------------------------
duly organized, validly existing and in good standing under the Laws of its
jurisdiction of organization, having all powers required to carry on its
business and enter into and carry out the transactions contemplated hereby. Each
Restricted Person is duly qualified, in good standing, and authorized to do
business in all other jurisdictions within the United States wherein the
character of the properties owned or held by it or the nature of the business
transacted by it makes such qualification necessary. Each Restricted Person has
taken all actions and procedures customarily taken in order to enter, for the
purpose of conducting business or owning property, each jurisdiction outside the
United States, if any, wherein the character of the properties owned or held by
it or the nature of the business transacted by it makes such actions and
procedures desirable.

     Section 5.3. Authorization. Each Restricted Person has duly taken all
                  -------------
action necessary to authorize the execution and delivery by it of the Loan
Documents to which it is a party and to authorize the consummation of the
transactions contemplated thereby and the performance of its obligations
thereunder.  Borrower is duly authorized to borrow funds hereunder.

     Section 5.4. No Conflicts or Consents. The execution and delivery by the
                  ------------------------
various Restricted Persons of the Loan Documents to which each is a party, the
performance by each of its obligations under such Loan Documents, and the
consummation of the transactions contemplated by the various Loan Documents, do
not and will not (a) conflict with any provision of (i) any Law, (ii) the
organizational documents of any Restricted Person, or (iii) any agreement,
judgment, license, order or permit applicable to or binding upon any Restricted
Person, (b) result in the acceleration of any Restricted Debt owed by any
Restricted Person, or (c) result in or require the creation of any Lien upon any
assets or properties of any Restricted Person except as expressly contemplated
in the Loan Documents. Except as expressly contemplated in the Loan Documents no
consent, approval, authorization or order of, and no notice to or filing with,
any Tribunal or third party is required in connection with the execution,
delivery or performance by any Restricted Person of any Loan Document or to
consummate any transactions contemplated by the Loan Documents.

                                      36
<PAGE>

     Section 5.5. Enforceable Obligations. This Agreement is, and the other
                  -----------------------
Loan Documents when duly executed and delivered will be, legal, valid and
binding obligations of each Restricted Person which is a party hereto or
thereto, enforceable in accordance with their terms except as such enforcement
may be limited by bankruptcy, insolvency or similar Laws of general application
relating to the enforcement of creditors' rights.

     Section 5.6. Initial Financial Statements. Borrower has heretofore
                  ----------------------------
delivered to each Lender true, correct and complete copies of the Initial
Financial Statements. The Initial Financial Statements fairly present each of
Inland Refining's and Parent's Consolidated financial position at the respective
dates thereof, the results of Inland Refining's operations and Inland Refining's
cash flows for the respective periods thereof, and the Consolidated results of
Parent's operations and Parent's Consolidated cash flows for the respective
periods thereof. Since the date of the annual Initial Financial Statements no
Material Adverse Change has occurred, except as reflected in the Disclosure
Schedule or a Disclosure Report. All Initial Financial Statements were prepared
in accordance with GAAP.

     Section 5.7. Other Obligations and Restrictions. As of the date hereof,
                  ----------------------------------
other than the Deferred Trade Payables, no Restricted Person has any outstanding
Debt of any kind (including obligations under farm-in agreements, other
obligations to make capital expenditures, contingent obligations, tax
assessments, and unusual forward or long-term commitments) which is, in the
aggregate, material to Borrower or material with respect to Parent's
Consolidated financial condition and not shown in the Initial Financial
Statements or disclosed in the Disclosure Schedule or a Disclosure Report. All
obligations of any Restricted Person to make capital expenditures to drill or
otherwise develop any oil, gas or mineral properties are specified in a
Disclosure Schedule or Disclosure Report (by well or project, describing the
dollar amount of each such obligation). Except as shown in the Initial Financial
Statements or disclosed in the Disclosure Schedule or a Disclosure Report, no
Restricted Person is subject to or restricted by any franchise, contract, deed,
charter restriction, or other instrument or restriction which is materially
likely to cause a Material Adverse Change. The Deferred Trade payables are in
the amounts set forth on Schedule 6 hereto as of the date hereof.

     Section 5.8. Full Disclosure. As of the date of delivery, no certificate,
                  ---------------
statement or other information delivered herewith or heretofore by any
Restricted Person to any Lender in connection with the negotiation of this
Agreement or in connection with any transaction contemplated hereby contains any
untrue statement of a material fact or omits to state any material fact known to
any Restricted Person (other than industry-wide risks normally associated with
the types of businesses conducted by Restricted Persons) necessary to make the
statements contained herein or therein not misleading as of the date made or
deemed made. There is no fact known to any Restricted Person (other than
industry-wide risks normally associated with the types of businesses conducted
by Restricted Persons) that has not been disclosed to each Lender in writing
which is materially likely to cause a Material Adverse Change. There are no
statements or conclusions in any Engineering Report which are based upon or
include misleading information or fail to take into account material information
regarding the matters reported therein, it being understood that each
Engineering Report is necessarily based upon professional opinions, estimates
and projections and that Borrower does not warrant that such opinions,

                                      37
<PAGE>

estimates and projections will ultimately prove to have been accurate. Borrower
has heretofore delivered to each Lender true, correct and complete copies of the
Initial Engineering Report.

     Section 5.9.  Litigation. Except as disclosed in the Initial Financial
                   ----------
Statements or in the Disclosure Schedule: (a) there are no actions, suits or
legal, equitable, arbitrative or administrative proceedings pending, or to the
knowledge of any Restricted Person threatened, against any Restricted Person
before any Tribunal which could cause a Material Adverse Change, and (b) there
are no outstanding judgments, injunctions, writs, rulings or orders by any such
Tribunal against any Restricted Person or any Restricted Person's stockholders,
partners, directors or officers which could cause a Material Adverse Change.

     Section 5.10. Labor Disputes and Acts of God. Except as disclosed in the
                   ------------------------------
Disclosure Schedule or a Disclosure Report, neither the business nor the
properties of any Restricted Person has been affected by any fire, explosion,
accident, strike, lockout or other labor dispute, drought, storm, hail,
earthquake, embargo, act of God or of the public enemy or other casualty
(whether or not covered by insurance), which could cause a Material Adverse
Change.

     Section 5.11. ERISA Plans and Liabilities. All currently existing ERISA
                   ---------------------------
Plans are listed in the Disclosure Schedule or a Disclosure Report. Except as
disclosed in the Initial Financial Statements or in the Disclosure Schedule or a
Disclosure Report, no Termination Event has occurred with respect to any ERISA
Plan and all ERISA Affiliates are in compliance with ERISA in all material
respects. No ERISA Affiliate is required to contribute to, or has any other
absolute or contingent liability in respect of, any "multiemployer plan" as
defined in Section 4001 of ERISA. Except as set forth in the Disclosure Schedule
or a Disclosure Report: (a) no "accumulated funding deficiency" (as defined in
Section 412(a) of the Internal Revenue Code) exists with respect to any ERISA
Plan, whether or not waived by the Secretary of the Treasury or his delegate,
and (b) the current value of each ERISA Plan's benefits does not exceed the
current value of such ERISA Plan's assets available for the payment of such
benefits by more than $500,000.

     all such permits, licenses and authorizations, and is also in compliance
     with all other limitations, restrictions, conditions, standards,
     prohibitions, requirements, obligations, schedules and timetables contained

using a generally accepted method of matching interest swap contracts to
declining principal balances, (ii) the floating rate index of each such contract
generally matches the index used to determine the floating rates of interest on
the corresponding indebtedness to be hedged by such contract and (iii) each such
contract is with a counterparty or have a guarantor of the obligation of the

covenant or agreement contained in any Loan Document, and each Lender Party may
enforce the payment of any Obligations due it or enforce any other legal or
equitable right which it may have. All rights, remedies and powers conferred
upon Lender Parties under the Loan Documents shall be deemed cumulative and not
exclusive of any other rights, remedies or powers available under the Loan
Documents or at Law or in equity.

                              ARTICLE IX - Agent
                                           -----

     Section 9.1  Appointment and Authority.  Each Lender Party hereby
                  -------------------------
irrevocably authorizes Agent, and Agent hereby undertakes, to receive payments
of principal, interest and other amounts due hereunder as specified herein and
to take all other actions and to exercise such powers under the Loan Documents
as are specifically delegated to Agent by the terms hereof or thereof, together
with all other powers reasonably incidental thereto. The relationship of Agent
to the other Lender Parties is only that of one commercial lender acting as
administrative agent for others, and nothing in the Loan Documents shall be
construed to constitute Agent a trustee or other fiduciary for any Lender Party
or any holder of any of the Notes or of any participation therein nor to impose
on Agent duties and obligations other than those expressly provided for in the
Loan Documents. With respect to any matters not expressly provided for in the
Loan Documents and any matters which the Loan Documents place within the
discretion of Agent, Agent shall not be required to exercise any discretion or
take any action, and it may request instructions from Lenders with respect to
any such matter, in which case it shall be required to act or to refrain from
acting (and shall be fully protected and free from liability to all Lender
Parties in so acting or refraining from acting) upon the instructions of
Required Lenders

                                      60

(including itself), provided, however, that Agent shall not be required to take
any action which exposes it to a risk of personal liability that it considers
unreasonable or which is contrary to the Loan Documents or to applicable Law.
Upon receipt by Agent from Borrower of any communication calling for action on
the part of Lenders or upon notice from any other Lender to Agent of any Default
or Event of Default, Agent shall promptly notify each other Lender thereof.

      Section 9.2  Exculpation, Agent's Reliance, Etc.  Neither Agent nor any of
                   ----------------------------------
its directors, officers, agents, attorneys, or employees shall be liable for any
action taken or omitted to be taken by any of them under or in connection with
the Loan Documents, INCLUDING THEIR NEGLIGENCE OF ANY KIND, except that each
shall be liable for its own gross negligence or willful misconduct. Without
limiting the generality of the foregoing, Agent (a) may treat the payee of any
Note as the holder thereof until Agent receives written notice of the assignment
or transfer thereof in accordance with this Agreement, signed by such payee and
in form satisfactory to Agent; (b) may consult with legal counsel (including
counsel for Borrower), independent public accountants and other experts selected
by it and shall not be liable for any action taken or omitted to be taken in
good faith by it in accordance with the advice of such counsel, accountants or
experts; (c) makes no warranty or representation to any other Lender and shall
not be responsible to any other Lender Party for any statements, warranties or
representations made in or in connection with the Loan Documents; (d) shall not
have any duty to ascertain or to inquire as to the performance or observance of
any of the terms, covenants or conditions of the Loan Documents on the part of
any Restricted Person or to inspect the property (including the books and
records) of any Restricted Person; (e) shall not be responsible to any other
Lender for the due execution, legality, validity, enforceability, genuineness,
sufficiency or value of any Loan Document or any instrument or document
furnished in connection therewith; (f) may rely upon the representations and
warranties of each Restricted Person or Lender Party in exercising its powers
hereunder; and (g) shall incur no liability under or in respect of the Loan
Documents by acting upon any notice, consent, certificate or other instrument or
writing (including any telecopy, telegram, cable or telex) believed by it to be
genuine and signed or sent by the proper Person or Persons.

      Section 9.3  Credit Decisions.  Each Lender Party acknowledges that it
                   ----------------
has, independently and without reliance upon any other Lender Party, made its
own analysis of Borrower and the transactions contemplated hereby and its own
independent decision to enter into this Agreement and the other Loan Documents.
Each Lender Party also acknowledges that it will, independently and without
reliance upon any other Lender Party and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under the Loan Documents.

      Section 9.4  Indemnification.  Each Lender agrees to indemnify Agent (to
                   ---------------
the extent not reimbursed by Borrower within ten (10) days after demand) from
and against such Lender's Percentage Share of any and all liabilities,
obligations, claims, losses, damages, penalties, fines, actions, judgments,
suits, settlements, costs, expenses or disbursements (including reasonable fees
of attorneys, accountants, experts and advisors) of any kind or nature
whatsoever (in this section collectively called "liabilities and costs") which
to any extent (in whole or in part) may be imposed on, incurred by, or asserted
against Agent growing out of, resulting from or in any other

                                      61
<PAGE>

way associated with any of the Collateral, the Loan Documents and the
transactions and events (including the enforcement thereof) at any time
associated therewith or contemplated therein (including any violation or
noncompliance with any Environmental Laws by any Person or any liabilities or
duties of any Person with respect to Hazardous Materials found in or released
into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM
OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT,

provided only that no Lender shall be obligated under this section to indemnify
Agent for that portion, if any, of any liabilities and costs which is
proximately caused by Agent's own individual gross negligence or willful
misconduct, as determined in a final judgment. Cumulative of the foregoing, each
Lender agrees to reimburse Agent promptly upon demand for such Lender's
Percentage Share of any costs and expenses to be paid to Agent by Borrower under
Section 10.4(a) to the extent that Agent is not timely reimbursed for such
expenses by Borrower as provided in such section.  As used in this section the
term "Agent" shall refer not only to the Person designated as such in Section
1.1 but also to each director, officer, agent, attorney, employee,
representative and Affiliate of such Person.

     Section 9.5  Rights as Lender.  In its capacity as a Lender, Agent shall
                  ----------------
have the same rights and obligations as any Lender and may exercise such rights
as though it were not Agent. Agent may accept deposits from, lend money to, act
as trustee under indentures of, and generally engage in any kind of business
with any Restricted Person or their Affiliates, all as if it were not Agent
hereunder and without any duty to account therefor to any other Lender.

     Section 9.6  Sharing of Set-Offs and Other Payments.  Each Lender Party
                  --------------------------------------
agrees that if it shall, whether through the exercise of rights under Security
Documents or rights of banker's lien, set off, or counterclaim against Borrower
or otherwise, obtain payment of a portion of the aggregate Obligations owed to
it which, taking into account all distributions made by Agent under Section 3.1,
causes such Lender Party to have received more than it would have received had
such payment been received by Agent and distributed pursuant to Section 3.1,
then (a)  it shall be deemed to have simultaneously purchased and shall be
obligated to purchase interests in the Obligations as necessary to cause all
Lender Parties to share all payments as provided for in Section 3.1, and (b)
such other adjustments shall be made from time to time as shall be equitable to
ensure that Agent and all Lender Parties share all payments of Obligations as
provided in Section 3.1; provided, however, that nothing herein contained shall
in any way affect the right of any Lender Party to obtain payment (whether by
exercise of rights of banker's lien, set-off or counterclaim or otherwise) of
indebtedness other than the Obligations. Borrower expressly consents to the
foregoing arrangements and agrees that any holder of any such interest or other
participation in the Obligations, whether or not acquired pursuant to the
foregoing arrangements, may to the fullest extent permitted by Law exercise any
and all rights of banker's lien, set-off, or

                                      62
<PAGE>

counterclaim as fully as if such holder were a holder of the Obligations in the
amount of such interest or other participation. If all or any part of any funds
transferred pursuant to this section is thereafter recovered from the seller
under this section which received the same, the purchase provided for in this
section shall be deemed to have been rescinded to the extent of such recovery,
together with interest, if any, if interest is required pursuant to Tribunal
order to be paid on account of the possession of such funds prior to such
recovery.

     Section 9.7  Investments.  Whenever Agent in good faith determines that it
                  -----------
is uncertain about how to distribute to Lender Parties any funds which it has
received, or whenever Agent in good faith determines that there is any dispute
among Lender Parties about how such funds should be distributed, Agent may
choose to defer distribution of the funds which are the subject of such
uncertainty or dispute. If Agent in good faith believes that the uncertainty or
dispute will not be promptly resolved, or if Agent is otherwise required to
invest funds pending distribution to Lender Parties, Agent shall invest such
funds pending distribution; all interest on any such Investment shall be
distributed upon the distribution of such Investment and in the same proportion
and to the same Persons as such Investment. All moneys received by Agent for
distribution to Lender Parties (other than to the Person who is Agent in its
separate capacity as a Lender Party) shall be held by Agent pending such
distribution solely as Agent for such Lender Parties, and Agent shall have no
equitable title to any portion thereof.

     Section 9.8  Benefit of Article IX.  The provisions of this Article (other
                  ---------------------
than the following Section 9.9) are intended solely for the benefit of Lender
Parties, and no Restricted Person shall be entitled to rely on any such
provision or assert any such provision in a claim or defense against any Lender.
Lender Parties may waive or amend such provisions as they desire without any
notice to or consent of Borrower or any Restricted Person.

     Section 9.9  Resignation.  Agent may resign at any time by giving written
                  -----------
notice thereof to Lenders and Borrower. Each such notice shall set forth the
date of such resignation. Upon any such resignation, Required Lenders shall have
the right to appoint a successor Agent. A successor must be appointed for any
retiring Agent, and such Agent's resignation shall become effective when such
successor accepts such appointment. If, within thirty days after the date of the
retiring Agent's resignation, no successor Agent has been appointed and has
accepted such appointment, then the retiring Agent may appoint a successor
Agent, which shall be a commercial bank organized or licensed to conduct a
banking or trust business under the Laws of the United States of America or of
any state thereof. Upon the acceptance of any appointment as Agent hereunder by
a successor Agent, the retiring Agent shall be discharged from its duties and
obligations under this Agreement and the other Loan Documents. After any
retiring Agent's resignation hereunder the provisions of this Article IX shall
continue to inure to its benefit as to any actions taken or omitted to be taken
by it while it was Agent under the Loan Documents.

     Section 10.  Waivers and Amendments; Acknowledgements.
                  ----------------------------------------

     (a)  Waivers and Amendments.  No failure or delay (whether by course of
          ----------------------
conduct or otherwise) by any Lender in exercising any right, power or remedy
which such Lender Party may have under any of the Loan Documents shall operate
as a waiver thereof or of any other right, power or remedy, nor shall any single
or partial exercise by any Lender Party of any such right, power or remedy
preclude any other or further exercise thereof or of any other right, power or
remedy. No waiver of any provision of any Loan Document and no consent to any
departure therefrom shall ever be effective unless it is in writing and signed
as provided below in this section, and then such waiver or consent shall be
effective only in the specific instances and for the purposes for which given
and to the extent specified in such writing. No notice to or demand on any
Restricted Person shall in any case of itself entitle any Restricted Person to
any other or further notice or demand in similar or other circumstances. This
Agreement and the other Loan Documents set forth the entire understanding
between the parties hereto with respect to the transactions contemplated herein
and therein and supersede all prior discussions and understandings with respect
to the subject matter hereof and thereof, and no waiver, consent, release,
modification or amendment of or supplement to this Agreement or the other Loan
Documents shall be valid or effective against any party hereto unless the same
is in writing and signed by (i) if such party is Borrower, by Borrower, (ii) if
such party is Agent, by such party, and (iii) if such party is a Lender, by such
Lender or by Agent on behalf of Lenders with the written consent of Required
Lenders (which consent has already been given as to the termination of the Loan
Documents as provided in Section 10.9). Notwithstanding the foregoing or
anything to the contrary herein, Agent shall not, without the prior consent of
each individual Lender, execute and deliver on behalf of such Lender any waiver
or amendment which would: (1) waive any of the conditions specified in Article
IV (provided that Agent may in its discretion withdraw any request it has made
under Section 4.3(f)), (2) reduce any fees payable to such Lender hereunder, or
the principal of, or interest on, such Lender's Note, (3) postpone any date
fixed for any payment of any such fees, principal or interest, (4) amend the
definition herein of "Required Lenders" or otherwise change the aggregate amount
of Percentage Shares which is required for Agent, Lenders or any of them to take
any particular action under the Loan Documents, (5) release Borrower from its
obligation to pay such Lender's Note or any Guarantor from its guaranty of such
payment.

     (b)  Acknowledgements and Admissions.  Borrower hereby represents,
          -------------------------------
warrants, acknowledges and admits that (i) it has been advised by counsel in the
negotiation, execution and delivery of the Loan Documents to which it is a
party, (ii) it has made an independent decision to enter into this Agreement and
the other Loan Documents to which it is a party, without reliance on any
representation, warranty, covenant or undertaking by Agent or any Lender,
whether written, oral or implicit, other than as expressly set out in this
Agreement or in another Loan Document delivered on or after the date hereof,
(iii) there are no representations, warranties, covenants, undertakings or
agreements by any Lender as to the Loan Documents except as expressly set out in
this Agreement or in another Loan Document delivered on or after the date
hereof, (iv) no Lender has any fiduciary obligation toward Borrower with respect
to any Loan

                                      64
<PAGE>

Document or the transactions contemplated thereby, (v) the relationship pursuant
to the Loan Documents between Borrower and the other Restricted Persons, on one
hand, and each Lender, on the other hand, is and shall be solely that of debtor
and creditor, respectively, (vi) no partnership or joint venture exists with
respect to the Loan Documents between any Restricted Person and any Lender,
(vii) Agent is not Borrower's Agent, but Agent for Lenders, (viii) should an
Event of Default or Default occur or exist, each Lender will determine in its
sole discretion and for its own reasons what remedies and actions it will or
will not exercise or take at that time, (ix) without limiting any of the
foregoing, Borrower is not relying upon any representation or covenant by any
Lender, or any representative thereof, and no such representation or covenant
has been made, that any Lender will, at the time of an Event of Default or
Default, or at any other time, waive, negotiate, discuss, or take or refrain
from taking any action permitted under the Loan Documents with respect to any
such Event of Default or Default or any other provision of the Loan Documents,
and (x) all Lenders have relied upon the truthfulness of the acknowledgements in
this section in deciding to execute and deliver this Agreement and to become
obligated hereunder.

     (c)  Representation by Lenders.  Each Lender hereby represents that it will
          -------------------------
acquire its Note for its own account in the ordinary course of its commercial
lending business; however, the disposition of such Lender's property shall at
all times be and remain within its control and, in particular and without
limitation, such Lender may sell or otherwise transfer its Note, any
participation interest or other interest in its Note, or any of its other rights
and obligations under the Loan Documents.

     (d)  Joint Acknowledgment.  This written Agreement and the other Loan
          --------------------
Documents represent the final agreement between the parties and may not be
contradicted by evidence of prior, contemporaneous, or subsequent oral
agreements of the parties.

     There are no unwritten oral agreements between the parties.

     Section 10.2. Survival of Agreements; Cumulative Nature.  All of Restricted
                   -----------------------------------------
Persons' various representations, warranties, covenants and agreements in the
Loan Documents shall survive the execution and delivery of this Agreement and
the other Loan Documents and the performance hereof and thereof, including the
making or granting of the Loans and the delivery of the Notes and the other Loan
Documents, and shall further survive until all of the Obligations are paid in
full to each Lender Party and all of Lender Parties' obligations to Borrower are
terminated. All statements and agreements contained in any certificate or other
instrument delivered by any Restricted Person to any Lender Party under any Loan
Document shall be deemed representations and warranties by Borrower or
agreements and covenants of Borrower under this Agreement. The representations,
warranties, indemnities, and covenants made by Restricted Persons in the Loan
Documents, and the rights, powers, and privileges granted to Lender Parties in
the Loan Documents, are cumulative, and, except for expressly specified waivers
and consents, no Loan Document shall be construed in the context of another to
diminish, nullify, or otherwise reduce the benefit to any Lender Party of any
such representation,

                                      65
<PAGE>

warranty, indemnity, covenant, right, power or privilege. In particular and
without limitation, no exception set out in this Agreement to any
representation, warranty, indemnity, or covenant herein contained shall apply to
any similar representation, warranty, indemnity, or covenant contained in any
other Loan Document, and each such similar representation, warranty, indemnity,
or covenant shall be subject only to those exceptions which are expressly made
applicable to it by the terms of the various Loan Documents.

     Section 10.3. Notices.  All notices, requests, consents, demands and other
                   -------
communications required or permitted under any Loan Document shall be in
writing, unless otherwise specifically provided in such Loan Document (provided
that Agent may give telephonic notices to the other Lender Parties), and shall
be deemed sufficiently given or furnished if delivered by personal delivery, by
telecopy or telex, by delivery service with proof of delivery, or by registered
or certified United States mail, postage prepaid, to Borrower and Restricted
Persons at the address of Borrower specified on the signature pages hereto and
to each Lender Party at its address specified on the signature pages hereto
(unless changed by similar notice in writing given by the particular Person
whose address is to be changed).  Any such notice or communication shall be
deemed to have been given (a) in the case of personal delivery or delivery
service, as of the date of first attempted delivery during normal business hours
at the address provided herein, (b) in the case of telecopy or telex, upon
receipt, or (c) in the case of registered or certified United States mail, three
days after deposit in the mail; provided, however, that no Borrowing Notice
shall become effective until actually received by Agent.

     Section 10.4.  Payment of Expenses; Indemnity.
                    ------------------------------

     (a)  Payment of Expenses.  Whether or not the transactions contemplated by
          -------------------
this Agreement are consummated, Borrower will promptly (and in any event, within
30 days after any invoice or other statement or notice) pay: (i) all transfer,
stamp, mortgage, documentary or other similar taxes, assessments or charges
levied by any governmental or revenue authority in respect of this Agreement or
any of the other Loan Documents or any other document referred to herein or
therein, (ii all reasonable costs and expenses incurred by or on behalf of Agent
(including attorneys' fees, consultants' fees and engineering fees, travel costs
and miscellaneous expenses) in connection with (1) the negotiation, preparation,
execution and delivery of the Loan Documents, and any and all consents, waivers
or other documents or instruments relating thereto, (2) the filing, recording,
refiling and re-recording of any Loan Documents and any other documents or
instruments or further assurances required to be filed or recorded or refiled or
re-recorded by the terms of any Loan Document, (3) the borrowings hereunder and
other action reasonably required in the course of administration hereof, (4)
monitoring or confirming (or preparation or negotiation of any document related
to) Borrower's compliance with any covenants or conditions contained in this
Agreement or in any Loan Document, and (ii all reasonable costs and expenses
incurred by or on behalf of any Lender Party (including attorneys' fees,
consultants' fees and accounting fees) in connection with the defense or
enforcement of any of the Loan Documents (including this Section) or the defense
of any Lender Party's exercise of its rights thereunder. In addition to the
foregoing, until and all Obligations have been paid in full, Borrower will also
pay or reimburse Agent for all reasonable out-of-pocket costs and expenses of
Agent or its agents or employees in connection with the continuing
administration of

                                      66
<PAGE>

the Loans and the related due diligence of Agent, including travel and
miscellaneous expenses and fees and expenses of Agent's outside counsel, reserve
engineers and consultants engaged in connection with the Loan Documents.

     (b)  Indemnity. Borrower and Parent each agree to indemnify each Lender
          ---------
Party, upon demand, from and against any and all liabilities, obligations,
claims, losses, damages, penalties, fines, actions, judgments, suits,
settlements, costs, expenses or disbursements (including reasonable fees of
attorneys, accountants, experts and advisors) of any kind or nature whatsoever
(in this section collectively called "liabilities and costs") which to any
extent (in whole or in part) may be imposed on, incurred by, or asserted against
such Lender Party growing out of, resulting from or in any other way associated
with any of the Collateral, the Loan Documents and the transactions and events
(including the enforcement or defense thereof) at any time associated therewith
or contemplated therein (including any violation or noncompliance with any
Environmental Laws by any Restricted Person or any liabilities or duties of any
Restricted Person or any Lender with respect to Hazardous Materials found in or
released into the environment).

The foregoing indemnification shall apply whether or not such liabilities and
costs are in any way or to any extent owed, in whole or in part, under any claim
or theory of strict liability, or are caused, in whole or in part, by any
negligent act or omission of any kind by any Lender Party,

provided only that no Lender Party shall be entitled under this section to
receive indemnification for that portion, if any, of any liabilities and costs
which is proximately caused by its own individual gross negligence or willful
misconduct, as determined in a final judgment. If any Person (including Borrower
or any of its Affiliates) ever alleges such gross negligence or willful
misconduct by any Lender, the indemnification provided for in this section shall
nonetheless be paid upon demand, subject to later adjustment or reimbursement,
until such time as a court of competent jurisdiction enters a final judgment as
to the extent and effect of the alleged gross negligence or willful misconduct.
As used in this section the term "Lender Party" shall refer not only to each
Person designated as such in Section 1.1 but also to each director, officer,
agent, attorney, employee, representative and Affiliate of such Person.

     Section 10.5. Joint and Several Liability; Parties in Interest;
                   -------------------------------------------------
Assignments.
- -----------

     (a)  All Obligations which are incurred by two or more Restricted Persons
shall be their joint and several obligations and liabilities.  All grants,
covenants and agreements contained in the Loan Documents shall bind and inure to
the benefit of the parties thereto and their respective successors and assigns;
provided, however, that no Restricted Person may assign or transfer any of its
rights or delegate any of its duties or obligations under any Loan Document
without the prior consent of Required Lenders.  Neither Borrower nor any
Affiliates of Borrower shall directly or indirectly purchase or otherwise retire
any Obligations owed to any Lender nor will any Lender accept any offer to do
so, unless each Lender shall have received substantially the

                                      67
<PAGE>

same offer with respect to the same Percentage Share of the Obligations owed to
it. If Borrower or any Affiliate of Borrower at any time purchases some but less
than all of the Obligations owed to all Lender Parties, such purchaser shall not
be entitled to any rights of any Lender under the Loan Documents unless and
until Borrower or its Affiliates have purchased all of the Obligations.

     (b)  No Lender shall sell any participation interest in its commitment
hereunder or any of its rights under its Loans or under the Loan Documents to
any Person other than an Eligible Transferee, and then only if the agreement
between such Lender and such participant at all times provides: (i) that such
participation exists only as a result of the agreement between such participant
and such Lender and that such transfer does not give such participant any right
to vote as a Lender or any other direct claims or rights against any Person
other than such Lender, (ii) that such participant is not entitled to payment
from any Restricted Person under Sections 3.2 through 3.6 of amounts in excess
of those payable to such Lender under such sections (determined without regard
to the sale of such participation), and (iii) unless such participant is an
Affiliate of such Lender, that such participant shall not be entitled to require
such Lender to take any action under any Loan Document or to obtain the consent
of such participant prior to taking any action under any Loan Document, except
for actions which would require the consent of all Lenders under subsection (a)
of Section 10.1. No Lender selling such a participation shall, as between the
other parties hereto and such Lender, be relieved of any of its obligations
hereunder as a result of the sale of such participation. Each Lender which sells
any such participation to any Person (other than an Affiliate of such Lender)
shall give prompt notice thereof to Agent and Borrower.

     (c)  Except for sales of participations under the immediately preceding
subsection (b), no Lender shall make any assignment or transfer of any kind of
its commitments or any of its rights under its Loans or under the Loan
Documents, except for assignments to an Eligible Transferee, and then only if
such assignment is made in accordance with the following requirements:

               (i)  Each such assignment shall apply to all Obligations owing to
     the assignor Lender hereunder and to the unused portion of the assignor
     Lender's commitments, so that after such assignment is made the assignor
     Lender shall have a fixed (and not a varying) Percentage Share in its Loans
     and Note and be committed to make that Percentage Share of all future
     Loans, the assignee shall have a fixed Percentage Share in such Loans and
     Note and be committed to make that Percentage Share of all future Loans,
     and the Percentage Share of the Borrowing Base of both the assignor and the
     assignee shall equal or exceed $5,000,000.

               (ii) The parties to each such assignment shall execute and
     deliver to Agent, for its acceptance and recording in the "Register" (as
     defined below in this section), an Assignment and Assumption in the form of
     Exhibit G, appropriately completed, together with the Note subject to such
     assignment and a processing fee payable to Agent of $2,500. Upon such
     execution, delivery, and payment and upon the satisfaction of the
     conditions set out in such Assignment and Assumption, then (i) Borrower
     shall issue new

                                      68
<PAGE>

     Notes to such assignor and assignee upon return of the old Notes to
     Borrower, and (ii) as of the "Settlement Date" specified in such Assignment
     and Assumption the assignee thereunder shall be a party hereto and a Lender
     hereunder and Agent shall thereupon deliver to Borrower and each Lender a
     schedule showing the revised Percentage Shares of such assignor Lender and
     such assignee Lender and the Percentage Shares of all other Lenders.

              (iii)  Each assignee Lender which is not a United States person
     (as such term is defined in Section 7701(a)(30) of the Internal Revenue
     Code) for Federal income tax purposes, shall (to the extent it has not
     already done so) provide Agent and Borrower with the "Prescribed Forms"
     referred to in Section 3.6(d).

     (d)  Nothing contained in this section shall prevent or prohibit any Lender
from assigning or pledging all or any portion of its Loans and Note to any
Federal Reserve Bank as collateral security pursuant to Regulation A of the
Board of Governors of the Federal Reserve System and any Operating Circular
issued by such Federal Reserve Bank; provided that no such assignment or pledge
shall relieve such Lender from its obligations hereunder.

     (e)  By executing and delivering an Assignment and Assumption, each
assignee Lender thereunder will be confirming to and agreeing with Borrower,
Agents and each other Lender Party hereunder that such assignee understands and
agrees to the terms hereof, including Article IX hereof.

     (f)  Agent shall maintain a copy of each Assignment and Assumption and a
register for the recordation of the names and addresses of Lenders and the
Percentage Shares of, and principal amount of the Loans owing to, each Lender
from time to time (in this section called the "Register"). The entries in the
Register shall be conclusive, in the absence of manifest error, and Borrower and
each Lender Party may treat each Person whose name is recorded in the Register
as a Lender hereunder for all purposes. The Register shall be available for
inspection by Borrower or any Lender Party at any reasonable time and from time
to time upon reasonable prior notice.

     Section 10.6. Confidentiality.  Each Lender Party agrees that it will take
                   ---------------
all reasonable steps to keep confidential any proprietary information given to
it by any Restricted Person, provided, however, that this restriction shall not
apply to information which (a) has at the time in question entered the public
domain, (b) is required to be disclosed by Law (whether valid or invalid) of any
Tribunal, (c) is disclosed to any Lender Party's Affiliates, auditors,
attorneys, or agents (provided such Persons are obligated to hold such
information in confidence on the terms provided in this section), (d) is
furnished to any other Lender Party or to any purchaser or prospective purchaser
of participations or other interests in any Loan or Loan Document (provided each
such purchaser or prospective purchaser first agrees to hold such information in
confidence on the terms provided in this section), or (e) is disclosed in the
course of enforcing its rights and remedies during the existence of an Event of

     Section 10.7. Governing Law; Submission to Process. Except to the extent
                   ------------------------------------
that the Law of another jurisdiction is expressly elected in a Loan Document,
the Loan Documents shall be deemed contracts and instruments made under the Laws
of the State of New York and shall be construed and enforced in accordance with
and governed by the Laws of the State of New York and the Laws of the United
States of America, without regard to principles of conflicts of law. Borrower
and Parent Each hereby agree that any legal action or proceeding against
Borrower or Parent with respect to this Agreement, the Notes or any of the Loan
Documents may be brought in the courts of the State of New York or of the United
States of America for the Southern District of New York as Lender Parties may
elect, and, by execution and delivery hereof, Each of Borrower and Parent
accepts and consents for itself and in respect to its property, generally and
unconditionally, the jurisdiction of the aforesaid courts, and further agrees to
a transfer of any such proceeding to a federal court sitting in the State of New
York to the extent that it has subject matter jurisdiction, and otherwise to a
state court in New York, New York, and agrees that such jurisdiction shall be
exclusive, unless waived by Lenders in writing, with respect to any action or
proceeding brought by it against Lender Parties and any questions relating to
usury. Each of parent and Borrower agrees that Sections 5-1401 and 5-1402 of the
General Obligations Law of the State of New York shall apply to the Loan
Documents and waives any right to stay or to dismiss any action or proceeding
brought before said courts on the basis of forum non conveniens. In furtherance
of the foregoing, Each of Parent and Borrower hereby irrevocably designates and
appoints CT Corporation System, 1633 Broadway, New York, New York, as Agent of
Borrower and Parent to receive service of all process brought against Borrower
or Parent with respect to any such proceeding in any such court in New York,
such service being hereby acknowledged by Borrower and Parent to be effective
and binding service in every respect. Copies of any such process so served shall
also, if permitted by Law, be sent by registered mail to Borrower at its address
set forth below, but the failure of Borrower to receive such copies shall not
affect in any way the service of such process as aforesaid. Borrower shall
furnish to Lender Parties a consent of CT Corporation System agreeing to act
hereunder prior to the effective date of this agreement. Nothing herein shall
affect the right of Lender Parties to serve process in any other manner
permitted by Law or shall limit the right of Lender Parties to bring proceedings
against Borrower or Parent in the courts of any other jurisdiction. If for any
reason CT Corporation System shall resign or otherwise cease to act as
Borrower's or Parent's agent, Borrower and Parent hereby irrevocably agree to
(a) immediately designate and appoint a new agent acceptable to Agent to serve
in such capacity and, in such event, such new agent shall be deemed to be
substituted for CT Corporation System for all purposes hereof and (b) promptly
deliver to Lenders the written consent (in form and substance satisfactory to
Agent) of such new agent agreeing to serve in such capacity.

     Section 10.8. Limitation on Interest. Lender Parties, Restricted Persons
                   ----------------------
and any other parties to the Loan Documents intend to contract in strict
compliance with applicable usury Law from time to time in effect. In furtherance
thereof such Persons stipulate and agree that none of the terms and provisions
contained in the Loan Documents shall ever be construed to create a contract to
pay, for the use, forbearance or detention of money, interest in excess of the
maximum amount of interest permitted to be charged by applicable Law from time
to time in effect. Neither any Restricted Person nor any present or future
guarantors, endorsers, or other Persons hereafter becoming liable for payment of
any Obligation shall ever be liable for unearned interest thereon or shall ever
be required to pay interest thereon in excess of the maximum amount that may be
lawfully contracted for, charged, or received under applicable Law from time to
time in effect, and the provisions of this section shall control over all other
provisions of the Loan Documents which may be in conflict or apparent conflict
herewith. Lender Parties expressly disavow any intention to contract for,
charge, or collect excessive unearned interest or finance charges in the event
the maturity of any Obligation is accelerated. If (a) the maturity of any
Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a
result any amounts held to constitute interest are determined to be in excess of
the legal maximum, or (c) any Lender or any other holder of any or all of the
Obligations shall otherwise collect moneys which are determined to constitute
interest which would otherwise increase the interest on any or all of the
Obligations to an amount in excess of that permitted to be charged by applicable
Law then in effect, then all sums determined to constitute interest in excess of
such legal limit shall, without penalty, be promptly applied to reduce the then
outstanding principal of the related Obligations or, at such Lender's or
holder's option, promptly returned to Borrower or the other payor thereof upon
such determination. In determining whether or not the interest paid or payable,
under any specific circumstance, exceeds the maximum amount permitted under
applicable Law, Lender Parties and Restricted Persons (and any other payors
thereof) shall to the greatest extent permitted under applicable Law, (i)
characterize any non-principal payment as an expense, fee or premium rather than
as interest, (ii exclude voluntary prepayments and the effects thereof, and (ii
amortize, prorate, allocate, and spread the total amount of interest throughout
the entire contemplated term of the instruments evidencing the Obligations in
accordance with the amounts outstanding from time to time thereunder and the
maximum legal rate of interest from time to time in effect under applicable Law
in order to lawfully contract for, charge, or receive the maximum amount of
interest permitted under applicable Law. As used in this section the term
"applicable Law" means the Laws of the State of New York or the Laws of the
United States of America, whichever Laws allow the greater interest, as such
Laws now exist or may be changed or amended or come into effect in the future.

      Section 10.9. Termination; Limited Survival. In its sole and absolute
                    -----------------------------
discretion Borrower may at any time that no Obligations are owing elect in a
written notice delivered to Agent to terminate this Agreement. Upon receipt by
Agent of such a notice, if no Obligations are then owing this Agreement and all
other Loan Documents shall thereupon be terminated and the parties thereto
released from all prospective obligations thereunder. Notwithstanding the
foregoing or anything herein to the contrary, any waivers or admissions made by
any Restricted Person in any Loan Document, any Obligations under Sections 3.2
through 3.6, and any obligations which any Person may have to indemnify or
compensate any Lender Party shall survive any termination of this Agreement or
any other Loan Document. At the request and

                                      71
<PAGE>

expense of Borrower, Agent shall prepare and execute all necessary instruments
to reflect and effect such termination of the Loan Documents. Agent is hereby
authorized to execute all such instruments on behalf of all Lenders, without the
joinder of or further action by any Lender.

      Section 10.10. Severability. If any term or provision of any Loan Document
                     ------------
shall be determined to be illegal or unenforceable all other terms and
provisions of the Loan Documents shall nevertheless remain effective and shall
be enforced to the fullest extent permitted by applicable Law.

      Section 10.11. Counterparts. This Agreement may be separately executed in
                     ------------
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to constitute one
and the same Agreement.

      Section 10.12. Waiver of Jury Trial, Punitive Damages, etc. To the extent
                     --------------------------------------------
permitted by Law, Lender Parties, Parent and Borrower hereby knowingly,
voluntarily, and intentionally waive any rights they may have to a trial by jury
in respect of any litigation based hereon, or directly or indirectly arising out
of, under, or in connection with, this Agreement or any other Loan Document, or
any course of conduct, course of dealing, statements (whether verbal or written)
or actions of such Persons, Parent or Borrower. This provision is a material
inducement for Lender Parties' entering into this Agreement and the other Loan
Documents. Parent, Borrower and each Lender Party hereby further (a) irrevocably
waives, to the maximum extent not prohibited by Law, any right it may have to
claim or recover in any such litigation any "Special Damages", as defined below,
(b) certifies that no party hereto nor any representative or agent or counsel
for any party hereto has represented, expressly or otherwise, or implied that
such party would not, in the event of litigation, seek to enforce the foregoing
waivers, and (c) acknowledges that it has been induced to enter into this
Agreement, the other Loan Documents and the transactions contemplated hereby and
thereby by, among other things, the mutual waivers and certifications contained
in this section. As used in this section, "Special Damages" includes all
special, consequential, exemplary, or punitive damages (regardless of how
named), but does not include any payments or funds which any party hereto has
expressly promised to pay or deliver to any other party hereto.

      Section 10.13. Amendment and Restatement. As of the Effective Date, this
                     -------------------------
Agreement amends and restates in its entirety the Existing Credit Agreement.
Borrower and Parent hereby represent and warrant that as of the Effective Date
all conditions under Section 4.1 of this Agreement have been met. Borrower and
Parent hereby agree that (i) the Loans outstanding under the Existing Credit
Agreement and all accrued and unpaid interest thereon, (ii) all Letters of
Credit issued and outstanding under the Existing Credit Agreement, and (iii) all
accrued and unpaid fees under the Existing Credit Agreement shall be deemed to
be outstanding under and payable by this Agreement; provided that changes in the
Percentage Shares, interest rates or fee rates shall not change the amounts
accrued and owing to each Lender under the Existing Credit

                                      72
<PAGE>

Agreement. The Percentage Shares and Commitments of the Lenders under this
Agreement are not the same as under the Existing Credit Agreement. To give
effect to such change, on the Effective Date, (i) Borrower hereby requests Loans
in the amount of $2,721,027.59 from MeesPierson Capital Corp., in the amount of
$747,225.19 from U.S. Bank National Association, (ii) subject to the terms and
conditions of this Agreement, each of MeesPierson Capital Corp. and U.S. Bank
National Association agrees to make such Loans to Borrower, (iii) Borrower
hereby requests the proceeds of such Loans be paid to ING (U.S.) Capital LLC
("ING"), in its capacity as a Lender hereunder, in order to reduce ING's
percentage share under the Existing Credit Agreement to the Percentage Share
listed on the Lender Schedule and (iv) Borrower will make such elections
regarding Interest Periods as Agent may request to cause each Lender to share in
each Eurodollar Loan based upon the Percentage Share under this Agreement as
soon as practical. By their execution hereof, each Lender consents to the
amendment or the amendment and restatement of the Security Documents under the
Existing Credit Agreement, as reflected in the documents listed on the Security
Schedule and consent to the execution and delivery by Agent of each of the
documents listed on the Security Schedule.

      Section 10.14. Release. As further consideration and to induce Agent and
                     -------
each Lender to enter into this Agreement, each of Borrower and Parent hereby
compromises, releases and discharges each Lender, Agent, and their respective
directors, members, managers, officers, shareholders, agents, employees,
representatives, attorneys, and their respective heirs, legal representatives,
successors and assigns (collectively, the "Lending Parties") from any and all
                                           ---------------
claims, demands, causes of action, remedies, suits, judgments, damages, expenses
and liabilities (collectively, "Claims") of any nature whatsoever, whether now
                                ------
know, suspected or claimed, whether arising under common law, in equity, or
under statute, which Borrower or Parent has against the Lending Parties which
may have arisen at any time on or prior to the Effective Date in connection
with, arising out of or related to the Loans, the Existing Credit Agreement, and
all instruments, documents, and agreements executed in connection therewith, or
the enforcement or attempted enforcement by Lending Parties of any of their
rights, remedies, or recourse related thereto.

     IN WITNESS WHEREOF, this Agreement is executed as of the date first written

Companies will pay all costs and expenses incurred by the Purchasers (a)
relating to the negotiation, execution and delivery of this Agreement and the
issuance of the New Securities (including, without limitation, reasonable fees,
office charges and expenses of counsel to TCW, Milbank, Tweed, Hadley & McCloy
LLP, and counsel to JEDI, Vinson & Elkins), (b) relating to printing the

the Purchasers for a breach by the Companies of their obligations hereunder, and
the Companies irrevocably agree that the Purchasers shall be entitled to the
remedy of specific performance or the granting of such other equitable remedies
as may be awarded pursuant to the arbitration described in Section 10.10 below
or by a court of competent jurisdiction after the arbitration in Section 10.10
below in order to afford the Purchasers the benefits of this Agreement and that
the Companies shall not object and hereby waive any right to object to such
remedy or such granting of other equitable remedies on the grounds that money
damages will not be sufficient to compensate the Purchasers.

  THE PARTIES AGREE THAT IF ANY DISPUTE SHOULD ARISE UNDER THE TERMS AND
PROVISIONS OF THIS AGREEMENT, EACH PARTY WAIVES ANY RIGHT TO COMMENCE LEGAL
ACTION OR ARBITRATION OTHER THAN AS PROVIDED UNDER THE TERMS OF THIS AGREEMENT,
AND THIS AGREEMENT SHALL PROVIDE THE SOLE AND EXCLUSIVE REMEDY FOR RESOLUTION OF
DISPUTES.

     (a)  THE DETERMINATION OF THE ARBITRATOR WILL BE FINAL AND BINDING UPON
EACH PARTY AND EACH PARTY SPECIFICALLY WAIVES ANY RIGHT TO CLAIM THAT THE
ARBITRATOR HAS EXCEEDED THE SCOPE OF THE ARBITRATION, HAS DISREGARDED EVIDENCE
OR PRINCIPLES OF LAW, AND FURTHER WAIVES ANY RIGHT TO DISCLAIM THE QUALIFICATION
OR FUNCTION OF THE ARBITRATOR IN ANY MANNER OR FASHION.

     (b)  IF SUCH A DISPUTE HAS ONLY TWO PARTIES, EACH PARTY SHALL SELECT
ONE ARBITRATOR, AND THOSE ARBITRATORS SHALL SELECT A THIRD ARBITRATOR.  IF THE
PARTIES DISPUTE THE SELECTION OF THE ARBITRATOR(S) AND CANNOT AGREE UPON THE
IDENTIFICATION OF THE ARBITRATOR(S) WITHIN THIRTY (30) DAYS FROM THE MAILING OF
THE OBJECTION, A PETITION FOR APPOINTMENT OF ARBITRATOR SHALL BE FILED WITH THE
SUPERIOR COURT OF THE COUNTY OF LOS ANGELES, CALIFORNIA.  IF SUCH A DISPUTE HAS
MORE THAN TWO PARTIES, ALL SUCH PARTIES SHALL WITHIN THIRTY (30) DAYS (i)
APPOINT TWO ARBITRATORS UPON AGREEMENT OF ALL SUCH PARTIES OR IF SUCH PARTIES
CANNOT SO AGREE (ii) APPROVE TWO ARBITRATOR'S SELECTED BY THE AMERICAN
ARBITRATION ASSOCIATION.  THE TWO ARBITRATORS SELECTED SHALL THEN SELECT A THIRD
ARBITRATOR.  THE ARBITRATION SHALL BE HELD IN LOS ANGELES, CALIFORNIA PURSUANT
TO THE COMMERCIAL ARBITRATION RULES OF THE AMERICAN ARBITRATION ASSOCIATION AND
THE NEW YORK CODE OF CIVIL PROCEDURE.

     (c)  THE ARBITRATOR'S FEES AND FEES AND COSTS OF PETITIONING FOR THE
APPOINTMENT OF THE ARBITRATOR SHALL BE PAID BY THE COMPANIES.  THE ARBITRATOR,
UPON RENDERING ITS AWARD, SHALL DETERMINE THE PARTY THAT PREVAILED BASED UPON
WRITTEN STATEMENTS MADE BY EACH PARTY AT THE COMMENCEMENT OF THE ARBITRATION AS
TO THE POSITION OF THE PARTIES AND THEIR ALTERNATIVES FOR SETTLING THE MATTER
AND THEREAFTER IN ACCORDANCE WITH THE RULES FOR THE FURTHER PRESENTATION OF
EVIDENCE AS SET FORTH BY THE ARBITRATOR.  A STATEMENT OF A PROPOSED SETTLEMENT
SHALL NOT BE BINDING UPON ANY PARTY AND SHALL NOT BE CONSIDERED AS EVIDENCE BY
THE ARBITRATOR EXCEPT TO THE EXTENT THAT THE ARBITRATOR UPON MAKING ITS SOLE AND
INDEPENDENT DETERMINATION SHALL DETERMINE THE PARTY WHICH PREVAILED BASED UPON
THE PROPOSALS FOR SETTLEMENT OF THE MATTER MADE BY EACH PARTY AND SHALL
DETERMINE THAT THE NON-PREVAILING PARTY SHALL PAY SOME OR ALL OF THE COSTS OF
ARBITRATION INCLUDING

35
<PAGE>

ANY COSTS INCURRED BY THE ARBITRATOR IN EMPLOYING EXPERTS TO ADVISE THE
ARBITRATOR IN REGARD TO SPECIFIC SUBJECTS OR QUESTIONS. THE ARBITRATOR MAY
FURTHER AWARD THE COST OF ATTORNEYS' FEES OR EXPERT WITNESSES CONSULTED OR
EMPLOYED IN THE PREPARATION OR PRESENTATION OF EVIDENCE TO THE ARBITRATOR BY THE
PREVAILING PARTY IF, IN THE ARBITRATOR'S DETERMINATION, THE POSITION OF THE
NONPREVAILING PARTY WAS NOT REASONABLY TAKEN OR MAINTAINED OR WAS BASED UPON A
FAILURE TO PROPERLY EXCHANGE OR COMMUNICATE INFORMATION WITH THE PREVAILING
PARTY IN REGARD TO THE SUBJECT SUBMITTED TO ARBITRATION.

     (d)  THE ARBITRATOR'S DETERMINATION MAY FURTHER PROVIDE FOR PROSPECTIVE
ENFORCEMENT AND DIRECTIONS FOR THE PARTIES TO COMPLY WITH INCLUDING WITHOUT
LIMITATION PERMANENT INJUNCTIVE RELIEF.  UNDER SUCH CIRCUMSTANCES, THE
ARBITRATOR'S AWARD SHALL BE BINDING UPON THE PARTIES AND SHALL BE UNDERTAKEN AND
PERFORMED BY EACH OF THE PARTIES UNTIL SUCH TIME AS THE ARBITRATOR'S DIRECTIONS
TO THE PARTY SHALL LAPSE BY THEIR TERM, OR THE ARBITRATOR SHALL NOTIFY THE
PARTIES THAT THOSE TERMS ARE NO LONGER IN FORCE OR EFFECT OR SHALL MODIFY THOSE
TERMS.

other than in an offering pursuant to a registration statement or pursuant to
Rule 144 (or any successor provision) under the Securities Act, any shares of
Common Stock or Series Z Preferred Stock held by such Transferor to any Person
SEP is the legal and beneficial holder of the Smith Securities
as set forth on Schedule A hereto next to its name.  SEP has neither previously
sold, assigned, conveyed, transferred or otherwise disposed of, in whole or in
part, its securities constituting all or a portion of the Smith Securities, nor,
as of the date hereof, has entered into any agreement to sell, assign,
other than an affiliate of Holdings (a "Transferee") in one transaction or a
                                        ----------
series of related transactions, which transfer or transfers constitute the
Transfer of a majority of the shares of Common Stock and Series Z Preferred
Stock held by Holdings and its affiliates as of the date hereof (a "Tag
                                                                    ---

- -----------                                                   --------------
and collectively, the "Tagalong Parties") shall have the right to sell to the
Transferee, on the same terms and conditions as provided with respect to the
sale by the Transferor to the Transferee, up to the number of shares of Common
Stock (rounded to the nearest whole share) equal to the product of (i) the total
number of shares of Common Stock which such Tagalong Party then owns and (ii) a
fraction with a numerator equal to the number of shares of Common Stock and
Series Z Preferred Stock then being sold by the Transferor and a denominator
equal to the total number of shares of Common Stock and Series Z Preferred Stock
owned by the Transferor. The right of the Transferor to sell shall be subject to
the condition that the Transferor shall cause the Transferee that proposes to
purchase the shares of the Transferor to offer to purchase, on such terms, such
number of shares from the Tagalong Parties; provided, however, that if the
Transferee is for any reason unwilling or unable to purchase the aggregate
number of shares from the Transferor together with the Tagalong Parties desiring
to Transfer shares in such transaction, then the number of shares to be sold by
each shall be proportionally reduced (based on the total number of shares
originally proposed to tag along or be sold) to such number as, when taken with
the number of shares to be sold by each other such party, shall be equal to the
number of shares which such Transferee is willing or able to purchase (provided
that such Transfer shall comply with the first sentence of this Section 3.1).

                                                           ---------
owns as of the date hereof; securities acquired after the date hereof in any
manner shall not be subject to the tagalong rights provided in this Section 3.
                                                                    ---------

     3.2       The Transferor shall give written notice to the Tagalong Parties
at least fifteen (15) business days prior to any proposed Transfer(s) of Common
Stock or Series Z Preferred Stock constituting a Tag Transaction. The notice
shall specify the proposed Transferee, the number of shares of Common Stock
and/or Series Z Preferred Stock to be sold, the amount and type of consideration
to be received therefor, and the place and date on which the sale is to be
consummated. If either, or both, of the Tagalong Parties desire to include
shares of Common Stock in such sale pursuant to Section 3.1, such Tagalong Party
                                                -----------
shall notify the Transferor not more than ten (10) business days after its
receipt of the notice from Transferor.

          3.3  The tagalong rights set forth in this Section 3 shall not be
                                                     ---------
transferable or assignable by JEDI or by members of the Smith Group, other than,
in each case, to their respective affiliates.

     SECTION 4.     DRAG-ALONG.

     4.1       If Transferor sells, other than in a public offering pursuant to
a registration statement or pursuant to Rule 144 (or any successor provision)
under the Securities Act, shares of Common Stock and/or Series Z Preferred Stock
held by such Transferor to a Transferee in one transaction or a series of
related transactions which constitute the transfer of a majority of the then
outstanding shares of Common Stock and Series Z Preferred Stock of the Issuer,
Holdings and/or its affiliates may, at their option, cause each of the members
of the Smith Group and JEDI (either party, and any affiliate thereof, being a
"Drag-Along Party" and collectively, the "Drag-Along Parties") to sell to the
 ----------------                         ------------------
Transferee, on the same terms and conditions as provided with respect to the
sale by Transferor to such Transferee, up to the number of shares of Common
Stock (rounded to the nearest whole share) equal to the product of (i) the total
number of shares of Common Stock which such Drag-Along Party then owns and (ii)
a fraction with a numerator equal to the number of shares of Common Stock and
Series Z Preferred Stock then being sold by the Transferor and a denominator
equal to the total number of shares of Common Stock and Series Z Preferred Stock
owned by the Transferor (such shares being "Drag-Along Shares" and such
                                            -----------------
transaction being a "Drag-Along Transaction"); provided however, that: (v)
                     ----------------------
Transferor shall only be entitled to drag along shares of Common Stock under
this Section 4 that the Drag-Along Party or Parties own as of the date hereof
     ---------
(securities acquired after the date hereof in any manner shall not be subject to
the drag-along rights provided in this Section 4); (w) Transferor may not
                                       ---------
receive more than the liquidation preference, plus accrued dividends thereon,
for the Series D Preferred Stock sold in a Drag-Along Transaction; (x) the price
for the Drag-Along Shares may not be lower than the price paid to other common
stockholders in the same or related transaction; (y) the consideration for the
Drag-Along Shares shall be paid in cash unless the relevant Drag-Along Party
consents to payment in a form other than cash; and (z)  if the Drag-Along
Transaction is a Merger Transaction, the provisions of this Section 4.1 shall
not apply to the Common Stock held by JEDI unless the Series E Preferred Stock
then held by JEDI is redeemed in cash as of or prior to the effective date of
the Merger Transaction.

     4.2       If any of the Drag-Along Parties proposes to Transfer to any of
its affiliates

                                       5
<PAGE>

any of the Common Stock held by such Drag-Along Party, then such Drag-Along
Party, as a condition to the exercise of such right of Transfer, shall cause
such Transferee to agree to be bound by this Section 4. The drag-along rights
                                             ---------
set forth in this Section 4 shall not be applicable to transferees of the Drag-
                  ---------
Along Parties other than to their respective affiliates.

     4.3       To exercise a drag-along right, Transferor shall give written
notice to the Drag-Along Party or Parties against whom the right is to be
enforced at least fifteen (15) business days prior to any proposed Transfer of
Common Stock and/or Series Z Preferred Stock.  The notice shall specify the
terms of such Transfer and certify as to the facts supporting exercise of the
drag-along right.  The Drag-Along Parties shall have ten (10) business days
after receipt of such notice (the "Drag-Along Notice Period") before such
                                   ------------------------
parties shall be required to Transfer their shares to the Transferee.  During
the Drag-Along Notice Period the Drag-Along Party or Parties in receipt of such
notice may not Transfer any Securities subject to Transferor's drag-along rights
under this Section 4 to any Person other than Transferor.
           ---------

     SECTION 5.     BOARD OF DIRECTORS REPRESENTATION; AUTHORIZATION AND
CONVERSION.

     5.1       Board of Directors Representation.  From and after the date
               ---------------------------------
hereof, each of Holdings, JEDI, the members of the Smith Group and any of their
respective affiliates who hold Voting Stock shall vote their respective shares
of voting stock (including any shares of Voting Stock hereafter acquired, owned
or controlled by such Holder), at any regular or special meeting of shareholders
of the Issuer called for the purpose of filling positions on the Board, or in
any written consent executed in lieu of such a meeting of shareholders, and
shall otherwise take all actions necessary to ensure that (i) the Board consists
of six (6) members, and (ii) that one (1) individual shall be designated for
election to the board by the holders of Common Stock and Series Z Preferred
Stock. Each of JEDI and Holdings agrees that neither it nor its respective
affiliates shall vote their respective shares of Common Stock and Series Z
Preferred Stock then owned by such parties in the election of the individual to
be elected to the Board by the holders of the Common Stock and the Series Z
Preferred Stock pursuant to clause 5.1(ii) above so long as such respective
party or its affiliates hold Series D Preferred Stock or Series E Preferred
Stock and the Smith Group continues to hold 10% or more of the combined
      ---
outstanding shares of Common Stock and Series Z Preferred Stock; provided,
however, that if Holdings and its affiliates shall not at such time hold Series
D Preferred Stock entitling it and its affiliates to elect four (4) members to
the Board, then Holdings may vote an amount of its Common Stock in the election
of directors in proportion to its reduction in number of directors it (and its
affiliates) are then entitled to appoint pursuant to the terms of the Series D
Preferred Stock. By way of example only, if Holdings (and its affiliates) may at
the time of an election elect only one (1) member to the Board pursuant to the
terms of their Series D Preferred Stock, then Holdings (and its affiliates)
shall be entitled to vote seventy-five percent (75%) of their Common Stock in
the election of directors by holders of the Common Stock. Each member of the
Smith Group agrees that it will not vote its respective shares of Common Stock
for the election of directors so long as the Smith Group continues to hold 10%
or more of the combined outstanding shares of Common Stock and Series Z
Preferred Stock; provided, further, that, notwithstanding the foregoing, if the
Smith Group does not for any reason vote its respective shares of Common Stock
for the election of directors, then both Holdings and JEDI and their affiliates
may vote their Common Stock and

                                       6
<PAGE>

Series Z Preferred Stock for the election of any director elected by holders of
Common Stock, in addition to directors that may be elected by holders of the
Series D Preferred Stock or the Series E Preferred Stock.

     5.2       Authorization and Conversion.  Until such time as all shares of
               -----------------------------
Series Z Preferred Stock is converted into Common Stock, each of Holdings, each
of the members of the Smith Group and JEDI, and each of their respective
affiliates and transferees, agree to vote their shares of Voting Stock at the
Issuer's next meeting of shareholders in favor of and otherwise cause the Issuer
to increase the number of shares of Common Stock authorized for issuance such
that the total number of authorized shares of Common Stock of the Issuer is
greater than or equal to the sum of (a) the number of outstanding shares of
Common Stock, (b) the number of shares required to convert to Common Stock all
outstanding shares of the Series Z Preferred Stock as provided in the Preferred
Stock Designation after giving effect to the Exchange, and (c) the number of
shares of Common Stock reserved for issuance pursuant to warrants and options
authorized for issuance under the Issuer's existing stock option plans or
agreements (the "Authorization") so that the Issuer can thereupon automatically
                 -------------
convert the Series Z Preferred Stock to Common Stock as provided in the
Preferred Stock Designation.  As soon as reasonably possible after obtaining the
Authorization, the Issuer shall cause the prompt filing of an amendment to the
Issuer's Articles of Incorporation with the Secretary of State of Washington to
give effect to the Authorization.

     SECTION 6.     WAIVER OF ANTI-TAKEOVER RIGHTS

          To the extent permitted by law, each of JEDI and its affiliates and
each of the members of the Smith Group and their affiliates, expressly waive all
rights and claims against Fund V, Holdings or the Issuer or otherwise with
respect to the transactions contemplated by the Exchange Agreement or any future
or subsequent transactions under any anti-takeover statutes of applicable law
including, but not limited to, Chapter 19 of the Washington Business Corporation
Act (RCW 23B.19.010 - 19.050).

     SECTION 7.     REPRESENTATIONS AND WARRANTIES; CONSENT TO EXCHANGE

          Each member of the Smith Group, respectively, hereby represents,
warrants and covenants as follows:


     7.1       Pengo is the legal and beneficial holders of the Smith Securities

               -------------------------

  This Agreement may be amended, and the observance of any term of this
Agreement may be waived only with the written consent of all parties adversely
effected or impacted by such waiver or amendment. No failure or delay on the
part of any of the parties in exercising any right, power or remedy hereunder

                   ----------------------------
Section 5 hereof, any holder of Registrable Common Stock may make a written
request to the Company for registration with the Commission under and in
accordance with the provisions of the Securities Act of the disposition of all
or part of the Registrable Common Stock (a "Demand Registration").  All requests
                                            -------------------
made pursuant to this Section 2(a) will specify the aggregate amount of

                                             ----------------------------
pursuant to Rule 415 under the Securities Act (or any similar rule that may be
adopted by the Commission).  If any holder intends to dispose of any of the
Registrable Common Stock pursuant to an underwritten offering, the holder will
have the right to select the underwriter.  No securities other than Registrable
Common Stock may be registered in connection with a Demand Registration without
the consent of the holders of a majority of the outstanding Registrable Common
Stock whose shares are subject to such Demand Registration.

(and its transferees) shall be entitled to initiate and have effected two (2)
Demand Registrations; and (iii) the Smith Group holds Registrable Common Stock,
it (and its transferees) shall be entitled to initiate and have effected one (1)
Demand Registration.  The Company shall pay all Registration Expenses of all
such Demand Registrations in accordance with Section 7 hereof.  The Company
shall not be deemed to have effected a Demand Registration unless and until (i)
the Company has filed a registration statement with the Commission and (ii) the
registration statement has been declared effective by the Commission.

          (c)      Grant of New Registration Rights.  From and after the date
                   --------------------------------
of this Agreement and until this Agreement is terminated, the Company shall not
grant any registration

2
<PAGE>

rights to any person that could adversely affect the rights of either of the
Purchasers hereunder or are inconsistent with the rights of either of the
Purchasers hereunder without the prior written consent of such Purchasers;
provided, however, that the granting of piggy-back registration rights that are
not superior to the registration rights granted under Section 4 hereof with
                                                      ---------
respect to cut-backs or reductions required by underwriters shall not, in and of
itself, be deemed to adversely affect the rights of either of the Purchasers or
be inconsistent with such rights.

          (d)  Termination of Prior Registration Rights.  By entering into this
               ----------------------------------------
Agreement JEDI, Portfolio and each of the members of the Smith Group, on behalf
of themselves and their affiliates,  expressly consents to and acknowledges that
any registration right(s) related to any securities of the Company held prior to
the date hereof by it is/are terminated as of the date hereof.

     Section 3.   Shelf Registration.
                  -------------------

The Company will, as soon as possible following a written request pursuant to
Section 2(a) for the registration of Registrable Common Stock by means of a
Shelf Registration Statement, file a shelf registration statement on Form S-3
covering the Registrable Common Stock and thereafter shall use its best efforts
to cause the Shelf Registration Statement to be declared effective as soon as
practicable following such filing and to take any and all reasonable action
within the Company's control, subject to and in accordance with Section 5, as
may be necessary or appropriate to maintain such effectiveness until such time
as neither any holder nor any of their assignees own any Registrable Common
Stock; provided however that the Company shall not be required to maintain the
effectiveness of any such Shelf Registration Statement for longer than (a) one
hundred and twenty days (120) from the effective date of such registration
statement for a Demand Registration initiated by the Smith Group; and (b) two
years from the effective date of such registration statement for a Demand
Registration initiated by either of the Purchasers.

     Section 4.   Piggy-back Registration.
                  ------------------------

(a)  If the Company proposes to file a registration statement under the
Securities Act with respect to an offering by the Company for its own account or
for the account of others (the "Initiating Shareholders") of any class of
                                -----------------------
security (other than pursuant to a registration statement on Forms S-4 or S-8
(or successor forms) or in connection with an exchange offer or an offering of
securities solely to the Company's existing stockholders), including a Demand
Registration Statement or a Shelf Registration Statement, then the Company shall
in each case give written notice of such proposed filing to the holders of
Registrable Common Stock (which notice shall indicate, to the extent then known,
the proposed managing underwriter or underwriters, if such offering is to be
underwritten, and such other terms of the proposed offering that the Company
reasonably believes to be material to the holders of Registrable Common Stock)
and shall include in such registration statement all or a portion of the
Registrable Common Stock owned by such holders which such holders shall request
to be so included by written notice given by such holders to the Company within
10 business days after such holder's receipt of such notice from the Company (a
"Piggy-back Registration").  The Company shall use its best efforts to effect
 -----------------------
the registration of all Registrable Common Stock requested to be so registered
in such offering on the same terms and conditions as any similar securities of
the Company included therein.  If the managing underwriter or underwriters of an
underwritten offering, if any, advise the holders of Registrable Common Stock in
writing that

3
<PAGE>

in its or their reasonable opinion or, in the case of a Piggyback Registration
not being underwritten, the Company shall reasonably determine (and notify the
holders of Registrable Common Stock of such determination), after consultation
with an investment banker of nationally recognized standing, that the number of
shares of Common Stock or other securities proposed to be sold in such
registration will adversely affect the success of such offering, the Company
will include in such registration the number of securities, if any, which, in
the opinion of such underwriter or underwriters, or the Company, as the case may
be, can be sold as follows: (A) if such registration was initiated by the
Company, (i) first, the shares the Company proposed to sell, (ii) second, the
             -----                                                ------
Registrable Common Stock and other shares of Common Stock requested to be
included in such registration by the holders thereof entitled to participate in

                                                        -----
requested to be included in such registration by the holders thereof entitled to
participate in such registration under registration rights agreements effective
after the date hereof.  To the extent that the privilege of including
Registrable Common Stock or other shares of Common Stock in any Piggyback
Registration must be allocated among the holders thereof pursuant to clause

number of shares of Common Stock that each such participant shall have requested
to include therein and to the extent that the privilege of including Common
Stock in any Piggyback Registration must be allocated among the holders thereof

shall have the right to discontinue any piggy-back registration under this
Section 4 at any time prior to the effective date of such registration if the
registration of the securities giving rise to such registration under this
Section 4 is discontinued by the Company, but no such discontinuation shall
preclude an immediate or subsequent request by the holders of Registrable Common
Stock for registration pursuant to Section

2 hereof if otherwise permitted.

     Section 5.  Restrictions on Dispositions and Demand Registrations.
                 ------------------------------------------------------

  Notwithstanding anything to the contrary contained herein, the Company shall
not be obligated to prepare and file any registration statement pursuant to a
Demand Registration or prepare or file any amendment or supplement thereto and
may suspend, by giving written notice to the holders of Registrable Common
Stock, such holders' rights to make dispositions of Registrable Common Stock
pursuant to a Shelf Registration Statement, at any time when the Company
reasonably believes that the filing thereof at the time requested, or the
offering or sale of securities pursuant thereto, would materially adversely
affect a pending or proposed public offering of the Company's securities, or an
acquisition, merger, recapitalization, consolidation, reorganization or similar
transaction or negotiations, discussions or pending proposals with respect
thereto.  The rights of holders of Registrable Common Stock to make dispositions
thereof pursuant to a Shelf Registration Statement may similarly be suspended by
the Company upon written notice to the holders of Registrable Common Stock that
the Shelf Registration Statement is unusable as a result of an event requiring a
post-effective amendment or supplement, which has not yet been filed, and will
remain unusable until the supplement is filed or post-effective amendment is
filed and declared effective. The filing of a registration statement, or any
amendment or supplement thereto, by the Company cannot be deferred, and the
holders' rights to dispose of Registrable Common Stock pursuant to a Shelf
Registration Statement cannot be suspended for more than 90 days, may not be so
deferred or suspended more than 180 days during any twelve month period unless
such deferral or suspension is agreed to in writing by the holders of
Registrable Common Stock subject to such suspension or deferral and, with
respect to suspended dispositions, the Company shall be obligated to maintain
the effectiveness of the applicable registration statement for an additional
period of time equal to the period of suspension(s).

     Section 6.  Registration Procedures.
                 -----------------------

          (a)    Certain Company Obligations.  Whenever Registrable Common
                 ---------------------------
Stock is to be registered pursuant to Sections 2 or 3 of this Agreement, the
Company will use reasonable diligence to effect the registration of such
Registrable Common Stock in accordance with the intended method of disposition
thereof as quickly as practicable, and in connection with any such request and
with the Piggy-back Registration or Demand Registration, the Company will as
expeditiously as possible:

               (i)       prepare and file with the Commission a registration
          statement which includes the Registrable Common Stock and use its best
          efforts to cause such registration statement to become effective
          (which registration statement, in the case of a Demand Registration,
          shall in all events be filed with the Commission within 60 days after
          the Company's receipt of the Demand Registration, subject to the
          limitations set forth in Section 5); provided that before filing a
          registration statement or prospectus or any amendments or supplements
          thereto, the Company will furnish to the holders of the Registrable
          Common Stock covered by such registration statement and the
          underwriters, if any, draft copies of all such documents proposed to
          be filed at least five (5) business days prior thereto, which
          documents will be subject to the reasonable review of such holders and
          underwriters, and provided further that if such registration statement
          refers to any holder of Registrable Common

3
<PAGE>

          Stock by name or otherwise as the holder of any securities of the
          Company, then such holder shall have the right to require (i) the
          insertion therein of language, in form and substance satisfactory to
          such holder, to the effect that the holding by such holder of such
          securities does not necessarily make such holder a "controlling
          person" of the Company within the meaning of the Securities Act and is
          not to be construed as a recommendation by such holder of the
          investment quality of the Company's securities covered thereby and
          that such holding does not imply that such holder will assist in
          meeting any future financial requirements of the Company, or (ii) in
          the event that such reference to such holder by name or otherwise is
          not required by the Securities Act or any rules and regulations
          promulgated thereunder, the deletion of the reference to such holder;

               (ii)   prepare and file as soon as reasonably practicable with
          the Commission such amendments and post-effective amendments to the
          registration statement as may be necessary to keep the registration
          statement effective for the period of time specified in Section 3 with
          respect to the Shelf Registration Statement and otherwise for 90 days
          (or such shorter period which will terminate when all Registrable
          Common Stock covered by such registration statement has been sold or
          withdrawn); cause the prospectus to be supplemented by any required
          prospectus supplement, and as so supplemented to be filed pursuant to
          Rule 424 under the Securities Act; and comply with the provisions of
          the Securities Act applicable to it with respect to the disposition of
          all securities covered by such registration statement during the
          applicable period in accordance with the intended methods of
          disposition by the holders thereof set forth in such registration
          statement or supplement to the prospectus;

               (iii)  furnish to any holder of Registrable Common Stock
          included in such registration statement and to the managing
          underwriter or underwriters, if any, without charge, at least one
          signed copy of the registration statement and any post-effective
          amendment thereto, upon request, and such number of conformed copies
          thereof and such number of copies of the prospectus (including each
          preliminary prospectus) and any amendments or supplements thereto, and
          any documents incorporated by reference therein, as such holder or
          underwriter may reasonably request in order to facilitate the
          disposition of the Registrable Common Stock being sold by such holder;

               (iv)   notify in writing each holder of Registrable Common
          Stock included in such registration statement, at any time when a
          prospectus relating-thereto is required to be delivered under the
          Securities Act, when the Company becomes aware of the happening of any
          event as a result of which the prospectus included in such
          registration statement (as then in effect) contains any untrue
          statement of a material fact or omits to state a material fact
          necessary to make the statements therein (in the case of the
          prospectus or any preliminary prospectus, in light of the
          circumstances under which they were made) not misleading and, as
          promptly as practicable thereafter, prepare and file with the
          Commission and furnish a supplement or amendment to such prospectus so
          that, as thereafter delivered to the purchasers of such Registrable
          Common Stock, such prospectus will not contain any

6
<PAGE>

          untrue statement of a material fact or omit to state a material fact
          necessary to make the statements therein, in light of the
          circumstances under which they were made, not misleading;

               (v)    use reasonable diligence to cause all Registrable
          Common Stock included in such registration statement to be listed, by
          the date of the first sale of Registrable Common Stock pursuant to
          such registration statement, on each securities exchange on which the
          Common Stock of the Company is then listed or proposed to be listed,
          if any, and use reasonable diligence to cause all Registrable Common
          Stock included in such Registration Statement to be quoted on The
          Nasdaq Stock Market (or other national or small-cap market), if the
          Common Stock of the Company is then quoted thereon;

               (vi)   make generally available to its security holders an
          earnings statement satisfying the provisions of Section 11(a) of the
          Securities Act as soon as practicable, which earnings statement shall
          cover the requisite 12-month period, which requirements will be deemed
          to be satisfied if the Company timely files complete and accurate
          information on Forms 10-Q, 10-K and 8-K under the Exchange Act and
          otherwise complies with Rule 158 under the Act as soon as feasible;

               (vii)  if requested by the managing underwriter or underwriters
          or any holder of Registrable Common Stock covered by the registration
          statement, promptly incorporate in a prospectus supplement or post-
          effective amendment such information as the managing underwriter or
          underwriters or such holder reasonably requests to be included
          therein, including, without limitation, with respect to the
          Registrable Common Stock being sold by such holder to such underwriter
          or underwriters, the purchase price being paid therefor by such
          underwriter or underwriters and with respect to any other terms of the
          underwritten offering of the Registrable Common Stock to be sold in
          such offering, and promptly make all required filings of such
          prospectus supplement or post-effective amendment;

               (viii) on or prior to the date on which the registration
          statement is declared effective, use reasonable diligence to register
          or qualify, and cooperate with the holders of Registrable Common Stock
          included in such registration statement, the underwriter or
          underwriters, if any, and their counsel, in connection with the
          registration or qualification of the Registrable Common Stock covered
          by the registration statement for offer and sale under the securities
          or blue sky laws of each state and other jurisdiction of the United
          States as any such holder or underwriter reasonably requests in
          writing, to use reasonable diligence to keep each such registration or
          qualification effective, including through new filings, or amendments
          or renewals, during the period such registration statement is required
          to be kept effective and to do any and all other acts or things
          necessary or advisable to enable the disposition in all such
          jurisdictions of the Registrable Common Stock covered by the
          applicable registration statement; provided that the Company will not
          be required to qualify generally to do business in any jurisdiction
          where it is not then so qualified or to take any action which would
          subject it to general service of process in any such jurisdiction
          where it is not then so subject;

7
<PAGE>

               (ix)   cooperate with the holders of Registrable Common Stock
          covered by the registration statement and the managing underwriter or
          underwriters, if any, to facilitate the timely preparation and
          delivery of certificates (not bearing any restrictive legends)
          representing securities to be sold under the registration statement,
          and enable such securities to be in such denominations and registered
          in such names as the managing underwriter or underwriters, if any, or
          such holders may request;

               (x)    enter into such customary agreements (including an
          underwriting agreement in customary form) and take all such other
          actions as the holders of the Registrable Common Stock being sold or
          the underwriters retained by holders participating in an underwritten
          public offering, if any, reasonably request in order to expedite or
          facilitate the disposition of such Registrable Common Stock;

               (xi)   make available for inspection by the holders, by any
          underwriter participating in any disposition to be effected pursuant
          to such registration statement and by any attorney, accountant or
          other agent retained by the holders or any such underwriter, all
          pertinent financial and other records, pertinent corporate documents
          and properties of the Company, and cause all of the Company's
          officers, directors and employees to supply all information,
          reasonably requested by the holders or any such seller, underwriter,
          attorney, accountant or agent in connection with such registration
          statement. In that connection, the Company may require the holders,
          such underwriter and such other persons to conduct their investigation
          in a manner which does not disrupt the operations of the Company and
          to execute such confidentiality agreements as the Company may
          reasonably determine to be advisable; and

               (xii)  notify each holder of Registrable Common Stock of any
          stop order issued or threatened by the Commission in connection with
          any registration statement covering Registrable Common Stock and take
          all reasonable actions required to prevent the entry of such stop
          order or to remove it if entered.

          (b)   Certain Obligations of Holders of Registrable Common Stock.
                ----------------------------------------------------------
Each holder of Registrable Common Stock shall provide the Company in writing
such information as the Company reasonably requests in order to effectuate the
registration and disposition of such holder's Registrable Common Stock pursuant
to this Agreement and such holder shall execute all consents, powers of
attorney, registration statements and other documents reasonably required to be
signed by such holder in order to effectuate the registration or disposition of
Registrable Common Stock by such holder.

     Section 7.  Registration Expenses.
                 ----------------------

  The Company shall pay all expenses incident to the Company's performance of or
compliance with its obligations hereunder, including, without limitation, all
registration, filing and National Association of Securities Dealers, Inc. fees,
all fees and expenses of complying with securities or blue sky laws, all word
processing, duplicating and printing expenses, messenger and delivery expenses,
and the reasonable fees and disbursements of the Company's independent public
accountants, of the Company's counsel and of one law firm acting as counsel to
the holders requesting registration of all or a portion of their Registrable
Common Stock.  Holders of Registrable Common Stock requesting registration will
be responsible for any other expenses incurred by them, including for their own
accountants and representatives, as well as any

underwriting discounts and commissions on the sale of the Registrable Common
Stock.

     Section 8.  Indemnification; Contribution.
                 ------------------------------

          (a)    Indemnification by the Company.
                 -------------------------------

The Company agrees to indemnify and hold harmless each holder of Registrable
Common Stock, its officers, directors, partners and members (and officers and
directors of such partners and members) and each person who controls such holder
(within the meaning of the Securities Act) against all losses, claims, damages
or liabilities arising out of or based upon any untrue or alleged untrue
statement of material fact contained in any registration statement registering
the disposition of Registrable Common Stock, any amendment or supplement
thereto, any prospectus or preliminary prospectus or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as the
same arise out of or are based upon, any such untrue statement or omission based
upon information furnished in writing to the Company by such indemnified person
expressly for use therein and will reimburse, as incurred, such holder, officer,
director, partner or controlling person for any legal or other expenses incurred
by such holder, officer, director, partner or controlling person in connection
with investigating, defending or appearing as a third party witness in
connection with any such loss, claim, damage, or liability.  In connection with
an underwritten offering, the Company will indemnify, and reimburse for
expenses, the underwriters thereof, their officers and directors and each person
who controls such underwriters (within the meaning of the Securities Act) to the
same extent as provided above with respect to holders of Registrable Common
Stock.
          (b)    Indemnification by Holders of Registrable Common Stock.  In
                 ------------------------------------------------------
connection with any registration statement in which a holder of Registrable
Common Stock is participating, such holder will furnish to the Company in
writing such information with respect to the name and address of such holder and
the amount of Registrable Common Stock held by such holder and such other
information as the Company shall reasonably request, for use in connection with
any such registration statement or prospectus and agrees to indemnify the
Company, its directors and officers, any underwriter (within the meaning of the
Securities Act) for the Company or other persons selling securities pursuant to
such registration statement, and each person who controls the Company, against
any losses, claims, damages, liabilities and expenses resulting from any untrue
statement of a material fact or any omission of a material fact required to be
stated in the registration statement or prospectus or any amendment thereof or
supplement thereto or necessary to make the statements therein not misleading,
to the extent, but only to the extent, that such untrue statement or omission is
contained in any information with respect to such holder so furnished in writing
by such holder expressly for inclusion in any prospectus or registration
statement.  In no event shall the liability of any selling holder of Registrable
Common Stock hereunder be greater in amount than the dollar amount of the
proceeds received by such holder upon the sale of the Registrable Common Stock
giving rise to such indemnification obligation.

          (c)    Conduct of Indemnification Proceedings.  Any person entitled
                 --------------------------------------
to indemnificaiton hereunder agrees to give prompt written notice to the
indemnifying party after the receipt by such person of any written notice of the
commencement of any action, suit, proceeding or investigation or threat thereof
made in writing as to which such person will claim indemnification or
contribution pursuant to this Agreement and, unless in the reasonable judgment
of such indemnified

9
<PAGE>

party a conflict of interest may exist between such indemnified party and the
indemnifying party with respect to such claim, permit the indemnifying party to
assume the defense of such claim with counsel reasonably satisfactory to such
indemnified party. The failure to notify the indemnifying party promptly of such
commencement or threat shall not relieve the indemnifying party of its
obligation to indemnify the indemnified party, except to the extent that the
indemnifying party is actually prejudiced by such failure. Whether or not such
defense is assumed by the indemnifying party, the indemnifying party will not be
subject to any liability for any settlement made without its consent (but such
consent will not be unreasonably withheld). No indemnifying party will consent
to entry of any judgment or enter into any settlement which does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect of such claim or
litigation. If the indemnifying party is not entitled to, or elects not to,
assume the defense of a claim, it will not be obligated to pay the fees and
expenses of more than one counsel for the indemnified party or parties with
respect to such claim, unless in the reasonable judgment of any indemnified
party an actual conflict of interest exists between such indemnified party and
any other of such indemnified parties with respect to such claim, in which event
the indemnified party shall be obligated to pay the fees and expenses of such
additional counsel or counsels.

          (d)    Contribution.  If the indemnification provided for in this
                 ------------
Section 8 from the indemnifying party is unavailable to an indemnified party
hereunder in respect of any losses, claims, damages, liabilities or expenses
referred to herein, then the indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or
expenses in such proportion as is appropriate to reflect the relative fault of
the indemnifying party and indemnified parties in connection with the actions
which resulted in such losses, claims, damages, liabilities or expenses, as well
as any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified parties shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact, has been made by, or related to
information supplied by, such indemnifying party or indemnified parties, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action. The amount paid or payable by a party as a
result of the losses, claims, damages, liabilities and expenses referred to
above shall be deemed to include, subject to the limitations set forth in
Section 8(b), any legal or other fees or expenses reasonably incurred by such
party in connection with any investigation or proceeding.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 8(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 8(d), no underwriter shall be
required to contribute any amount in excess of the amount by which the
underwriting discount applicable to the Registrable Common Stock purchased by it
and distributed to the public exceeds the amount of any damages which such
underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and no selling holder
shall be required to contribute any amount in excess of the amount by which the
total price at which the Registrable Common Stock of such selling holder was
offered to the public exceeds the amount of any damages which such selling
holder has otherwise been required to pay by reason of such untrue

10
<PAGE>

statement or omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

          The obligations of the Company pursuant to this Section 8 shall be
further subject to such additional express agreements of the Company as may be
required to facilitate an underwritten offering, provided that no such agreement
shall in any way limit the rights of the holders of Registrable Common Stock
under this Agreement, or create additional obligations of such holders not set
forth herein, except as otherwise expressly agreed in writing by any such
holders.  The obligations of the Company pursuant to this Section 8 shall be in
addition to any liability or obligation the Company may have at common law or
otherwise.

     Section 9.  Rule 144.
                 ---------

  The Company covenants that for so long as any Holder owns any Registrable
Common Stock that it will file, in a timely manner, the reports required to be
filed by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the Commission thereunder, and it will take such further
action as any holder of Registrable Common Stock may reasonably request, all to
the extent required from time to time to enable such holder to sell Registrable
Common Stock without registration under the Securities Act within the limitation
of the exemptions provided by (a) Rule 144 under the Securities Act, as such
Rule may be amended from time to time, or (b) any similar rule or regulation
hereafter adopted by the Commission.  Upon the request of any holder of
Registrable Common Stock, the Company will deliver to such holder a written
statement as to whether it has complied with such requirements.

     Section 10. Remedies.
                 ---------

   Each holder of Registrable Common Stock in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Agreement.  The
Company agrees that monetary damages would not be adequate compensation for any
loss incurred by reason of a breach by it of the provisions of this Agreement
and hereby agrees to waive the defense in any action for specific performance
that a remedy at law would be adequate.

     Section 11. Binding Effect; Transferees; Termination.
                 -----------------------------------------

  Except to the extent otherwise provided herein, the provisions of this
Agreement shall be binding upon and accrue to the benefit of the parties hereto
and their respective heirs, legal representatives, successors and assigns.  A
transferee of Registrable Common Stock, which acquires such securities from a
holder of Registrable Common Stock in a transfer, whether in a public
distribution or otherwise, which results in such transferred securities not
being Registrable Common Stock in the hands of such transferee, shall not be a
holder of Registrable Common Stock hereunder and shall not have any rights or
obligations hereunder as a result of such transfer of Registrable Common Stock.
Except as provided in the preceding sentence, a transferee of a holder of
Registrable Common Stock, whether becoming such by sale, transfer, assignment,
operation of law or otherwise, shall be deemed to be a holder of Registrable
Common Stock hereunder and such transferee shall be entitled to the rights, and
subject to the obligations, of such a holder hereunder. This Agreement shall
terminate at such time as there are no outstanding shares of Registrable Common
Stock.

     Section 12. Amendments and Waivers.
                 -----------------------

   Except as otherwise provided herein, the provisions of this Agreement may not
be amended, modified or supplemented without the written agreement of each of
