THIS AMENDMENT NO. 2 RELATES TO THE SCHEDULE 13D ORIGINALLY FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION ON JULY 31, 1997, WHICH WAS AMENDED BY
AMENDMENT NO. 1 THERETO FILED WITH THE SECURITIES AND EXCHANGE COMMISSION ON
JANUARY 16, 1998, ITEMS 3, 4, 5, 6 AND 7 OF WHICH ARE HEREBY FURTHER AMENDED BY
THE ADDITION OF THE FOLLOWING:

Item 3.  Source and Amount of Funds or Other Consideration:

         On September 21, 1999, JEDI II exchanged the 100,000 shares of the
Issuer's Preferred Stock, including $2.2 million of accumulated and unpaid
dividends thereon, for (i) 2,920,975 shares of the Issuer's Common Stock and
(ii) 121,973 shares of the Issuer's Series E Redeemable Preferred Stock (the
"Series E Preferred Stock"), pursuant to an Exchange Agreement dated as of
September 21, 1999, among the Issuer, Inland Production Company, a Texas
corporation, Inland Refining, Inc., a Utah corporation, Trust Company of the
West, a California trust company, 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., a California limited partnership ("Portfolio,"
and collectively with Fund V, "TCW"), Inland Holdings LLC, a California limited
liability company ("Holdings"), and JEDI II (the "Exchange Agreement"). Under
the Exchange Agreement, if any of the outstanding options and warrants of the
Issuer, which are exercisable for 1,291,651 shares of Common Stock are
exercised, JEDI II has been granted an option at the same exercise price to
acquire a number of shares of Common Stock equal to one-third of the shares
issued pursuant to such exercised option or warrant. In connection with the
Exchange Agreement, the Issuer paid to JEDI II $25,000 and all of its related
costs and expenses. The Exchange Agreement is incorporated herein by reference
to Exhibit 6.

Item 4.  Purpose of Transaction:

         On September 21, 1999, JEDI II exchanged the 100,000 shares of the
Issuer's Preferred Stock, including $2.2 million of accumulated and unpaid
dividends thereon, for (i) 2,920,975 shares of the Issuer's Common Stock and
(ii) 121,973 shares of Series E Preferred Stock, pursuant to the Exchange
Agreement. Under the Exchange Agreement, if any of the outstanding options and
warrants of the Issuer, which are exercisable for 1,291,651 shares of Common
Stock are exercised, JEDI II has been granted an option at the same exercise
price to acquire a number of shares of Common Stock equal to one-third of the
shares issued pursuant to such exercised option or warrant.

         The Series E Preferred Stock accrues dividends on a daily basis. At
the option of the Issuer, dividends shall accrue and be paid (i) at the rate of
$2.3125 per share per quarter if paid in cash on a current basis in arrears on
the dividend payment date for such quarter or (ii) at a rate of $2.875 per
share per quarter if accumulated and not paid on the dividend payment date of
the quarter in which accrued. Dividends shall be paid on each December 30,
March 30, June 29 and September 29, commencing December 30, 1999. Additional
dividends shall accrue and be payable on the amount of dividends accrued but
unpaid, whether or not declared, compounding quarterly, at a rate of 11.50% per
annum. No dividends may be declared or paid on the Issuer's Common Stock or
Series Z Preferred Stock while there are any accrued and unpaid dividends on
the Series E Preferred Stock and the Issuer's Series D Redeemable Preferred
Stock (the "Series D Preferred Stock"). The Series E Preferred Stock has
liquidation preference over all other classes and series of stock, except the
Issuer's Series D Preferred Stock, in an amount equal to $100.00 per share,
together with any accrued and unpaid dividends thereon. The Series E Preferred
Stock may be redeemed, in whole or in part, at any time by the Issuer at its
option by paying an amount in cash equal to $100.00 per share, together with
any accrued and unpaid dividends thereon (the "Series E Redemption Price"). On
the earlier of (i) September

                                  Page 4 of 8

<PAGE>   5



21, 2006 or (ii) the redemption of all outstanding shares of the Series D
Preferred Stock, all of the outstanding Series E Preferred Stock must be
redeemed by the Issuer at the Series E Redemption Price.

         The Series E Preferred Stock votes together with the Issuer's Common
Stock, Series D Preferred Stock and Series Z Convertible Preferred Stock (the
"Series Z Preferred Stock") as a single class and not as a separate voting
group or class, except as mandated by law or by the Issuer's Articles of
Incorporation as described below. Each share of the Series E Preferred Stock
and the Series D Preferred Stock is entitled to vote with the Common Stock on a
share-for-share basis on all matters submitted to the shareholders of the
Issuer for approval, and each share of the Series Z Preferred Stock is entitled
to vote with the Common Stock on a share-for-share basis, but is entitled to
the number of votes that 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 Issuer's Articles of Incorporation, the total number of votes
of the combined class of Common Stock, Series E Preferred Stock, Series D
Preferred Stock and Series Z Preferred Stock presently outstanding is
39,856,310 votes, of which 3,042,948 votes, representing approximately 7.63% of
the total, are owned by JEDI II.

         Pursuant to the Issuer's Articles of Incorporation, the holders of the
Series E Preferred Stock, acting separately as a class, have the right to elect
one of the members of the Board of Directors of the Issuer. If the number of
members of the Issuer's Board increases to a number greater than six, the
holders of the Series E Preferred Stock have the right to elect that number of
directors equal to one-sixth of the directors comprising the Board. The
approval of a majority of the outstanding shares of Series E Preferred Stock,
voting as a separate voting group, is required for the authorization or
issuance of any additional shares of the Issuer's Series D Preferred Stock or
Series E Preferred Stock or the designation of one or more additional series of
Class A preferred stock or any other class of stock of the Issuer with
dividend, liquidation or redemption rights pari passu with or having priority
over or having greater or more beneficial rights per share than the Series E
Preferred Stock. Additionally, the approval of 75% of the outstanding shares of
Series E Preferred Stock, voting as a separate voting group, is required for
the Issuer to: (i) consummate any merger where the Issuer is not the surviving
entity or any transaction where the holders of voting stock of the Issuer prior
to such transaction own less than 50% of the outstanding voting stock of the
Issuer after such transaction unless, in either case, the holders of the Series
E Preferred Stock shall receive shares with substantially the same rights and
preferences as the Series E Preferred Stock, (ii) consummate any merger in
which the holders of the Issuer's Common Stock receive any consideration in
exchange for their Common Stock other than common stock of the surviving
corporation or securities of the surviving corporation junior to the securities
issued to the holders of the Series E Preferred Stock, (iii) sell or transfer
substantially all of the Issuer's assets unless, so long as the Series D
Preferred Stock is outstanding, (A) at least 60% of the outstanding shares of
Series E Preferred Stock is redeemed or (B) holders of the Series E Preferred
Stock receive an amount equal to 60% of 10/85ths of the total consideration
received by the holders of the Series D Preferred Stock and the Series E
Preferred Stock in the same 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 upon the redemption of 20% of the outstanding shares of
Series E Preferred Stock, or (iv) modify any rights of the Series E Preferred
Stock in any way adverse to the holders of the Series E Preferred Stock.

         JEDI II intends to review its investment in the Issuer on a continuing
basis and, depending upon the price of, and other market conditions relating
to, the Common Stock, subsequent developments affecting the Issuer, the
Issuer's business and prospects, other investment and business opportunities
available to JEDI II, general stock market and economic conditions, tax
considerations and other factors deemed relevant, may decide to increase or
decrease the size of its investment in the Issuer.

         Other than the transactions described herein, none of the Reporting
Entities, nor to their knowledge, ECMLP II, ECC II, Enron North America Corp.,
a Delaware corporation formerly known as Enron Capital & Trade Resources Corp.
("ENA"), or any person listed on Schedule I hereto, has any plan or proposal
that would result in any of the consequences listed in paragraphs (a) - (j) of
Item 4 of Schedule 13D.

Item 5.  Interest in Securities of the Issuer:

         As of the date of this statement, JEDI II beneficially owns and has
the power to vote and dispose of (i) 2,920,975 shares of the Issuer's Common
Stock, representing approximately 12.65% of the Issuer's Common Stock
outstanding as of September 21, 1999, and (ii) 121,973 shares of the Issuer's
Series E Redeemable Preferred Stock. Because ECC II is an indirect, wholly
owned subsidiary of Enron, Enron may also be deemed to beneficially own such
shares. Enron disclaims beneficial ownership of all such shares.

         Other than the transactions described herein, none of the Reporting
Entities, nor to their knowledge, ECMLP II, ECC II, ENA, or any person listed
on Schedule I hereto, has effected any transactions in shares of Common Stock
of the Issuer during the preceding sixty days.

Item 6.  Contracts, Arrangements, Understandings or Relationships With
         Respect to Securities of the Issuer:

         Pursuant to the Exchange Agreement, JEDI II released the Issuer from
all claims, demands and causes of action under the Securities Purchase
Agreement dated July 21, 1997, the Registration Rights Agreement dated July 21,
1997 and the Tagalong Agreement dated July 21, 1997, which are filed as
Exhibits 1, 2 and 3, respectively.

         JEDI II entered into a Registration Rights Agreement dated as of
September 21, 1999 with the Issuer, Holdings, Portfolio, Pengo Securities
Corp., a Delaware corporation ("Pengo"), Smith Energy Partnership, a New York
general partnership ("SEP"), Randall D. Smith, Jeffrey A. Smith, Barbara
Stovall Smith, John W. Adams and Arthur J. Pasmas (collectively, the "Smith
Individuals")(Pengo, SEP and the Smith Individuals, together with any of their
respective affiliates, the "Smith Group")(the "Registration Rights Agreement").
Pursuant to the Registration Rights Agreement, the Issuer granted JEDI II
certain demand and piggyback registration rights relating to the Common Stock
acquired by JEDI II in the exchange described under Item 4 above. The
Registration Rights Agreement is incorporated herein by reference to Exhibit 7.

         In addition, JEDI II entered into a Shareholders Agreement dated as of
September 21, 1999 with the Issuer, Holdings, Fund V and the Smith Group.
Pursuant to the Shareholders Agreement, if Holdings or any of its affiliates
transfers, other than in an offering pursuant to a registration statement or
pursuant to Rule 144 under the Securities Act of 1933 (the "Securities Act"),
any shares of Common Stock or Series Z Preferred Stock held by such transferor
to any person other than an affiliate of Holdings 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 September 21, 1999, then each
of JEDI II and the Smith Group may sell to the transferee up to the number of
shares of Common Stock equal to the product of (i) the total number of shares
which JEDI II or the Smith Group, as the case may be, 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. If Holdings or any of its affiliates sells,
other than in an offering pursuant to a registration statement or pursuant to
Rule 144 under the Securities Act, shares of the Issuer's Common Stock or
Series Z Preferred Stock 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

                                  Page 6 of 8

<PAGE>   7



Series Z Preferred Stock, then Holdings and/or its affiliates may, at their
option, and subject to certain conditions, cause each of the members of JEDI II
and the Smith Group to sell to the transferee up to the number of shares of
Common Stock equal to the product of (i) the total number of shares of Common
Stock which JEDI II or the Smith Group, as the case may be, 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. If Holdings, Fund V or Portfolio (or their
affiliate transferees) endeavors to purchase shares of Common Stock from any
person (other than a party to the Shareholders Agreement or an affiliate),
Holdings has agreed to offer to buy a proportionate number of shares of Common
Stock from each member of the Smith Group and JEDI II equal in aggregate amount
to the amount they endeavor to purchase or the total number of shares of Common
Stock then held by members of the Smith Group and JEDI II, whichever is less,
based on the number of shares of Common Stock to be purchased by Holdings, Fund
V or Portfolio (or their affiliate transferees). Holdings, JEDI II and the
Smith Group also agreed with each other to vote their respective shares of
voting stock to ensure that (i) the Board of Directors of the Issuer consists
of six members and (ii) one member is designated for election to the Board by
the holders of Common Stock and Series Z Preferred Stock. Each of JEDI II and
Holdings further agreed that neither it nor its affiliates would vote their
shares of Common Stock and Series Z Preferred Stock in the election of such one
designated Board member so long as they own Series E Preferred Stock or Series
D 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, that if Holdings and its affiliates do not at such time hold enough
Series D Preferred Stock to entitle it and its affiliates to elect four members
to the Board, then Holdings may vote an amount of its Common Stock
proportionate to the reduction in number of directors it and its affiliates are
entitled to designate pursuant to the terms of the Series D Preferred Stock.
Each member of the Smith Group agreed not to vote its 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. If the Smith Group does not vote its shares of Common Stock
for the election of directors, then both Holdings and JEDI II and their
affiliates may vote their Common Stock and Series Z Preferred Stock for the
election of any director elected by the holders of Common Stock, in addition to
directors that may be elected by the holders of the Series D Preferred Stock or
the Series E Preferred Stock. The Shareholders Agreement is incorporated herein
by reference to Exhibit 8.

                  3.3 Information Regarding the Issuer.

                  (a) The audited consolidated financial statements of the
Issuer and its Subsidiaries as filed with the Commission in accordance with the
reporting requirements of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), for the three most recent fiscal years (and the unaudited
interim periods reported therein and through the date hereof) (collectively, the
"Financial Statements") fairly present in all material respects the financial
position of the Issuer and its Subsidiaries as of the respective dates of such
balance sheets and the results of the Issuer and its Subsidiaries operations for
the respective periods covered by such statements of operations, stockholders'
equity and cash flows, and have been prepared in accordance with GAAP
consistently applied throughout the periods involved. There are no material
liabilities, contingent or otherwise, of the Issuer and its Subsidiaries as of
the date hereof and as of the Closing Date required to be reflected in a balance
sheet prepared in accordance with GAAP which are not reflected in such balance
sheets. Since the date of the Issuer's most recent quarterly report on form 10-Q
(the "10-Q Filing Date"), there have been no changes in the assets, liabilities
or financial position of the Issuer and its Subsidiaries from that set forth in
the balance sheet as of such date, other than changes in the ordinary course of
business which have not, either individually or in the aggregate, had a Material
Adverse Effect on the Companies taken as a whole.

                  (b) As of their respective dates, the Financial Statements did
not contain any untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. Since the 10-Q Filing
Date, there has been no change in the business, properties, financial condition
or operations which has had a Material Adverse Effect on the Companies taken as
a whole.

                  3.4 Independent Engineering Report. The Companies have
delivered to the Purchasers, in form satisfactory to the Purchasers, results of
the Initial Independent Engineering Report on the fields and properties listed
therein or attached thereto (the "Evaluated Properties") in which the Companies
will have interests as of the Closing Date. The Initial Independent Engineering
Report is the latest engineering report available to the Companies relating to
the Evaluated Properties. To the knowledge of the Responsible Officers, the
Companies have provided no materially false or misleading information to and
have not withheld from the engineer preparing or who prepared the Initial
Independent Engineering Report any material information with respect to the
preparation of the Independent Engineering Report. The Responsible Officers and
the officers of Refining are not aware of any facts or circumstances that should
reasonably cause the Companies to conclude that (i) any of the information that
was supplied by the Companies to the Independent Engineer in connection with its
preparation of the Independent Engineering Report was not correct or (ii) the
Independent Engineering Report is incorrect in any material respect.

                  3.5 Litigation. Except as set forth in Schedule 3.5, (i) there
are no actions, suits, investigations or legal, equitable, arbitrative or
administrative proceedings pending or, to the knowledge of any Responsible
Officer of the Companies, currently threatened against the Companies or the
Subsidiaries before any Governmental Body which could cause a Material Adverse
Effect on the Companies , either individually or in the aggregate; and (ii)
there are no outstanding judgments, injunctions, writs, rulings or orders by any
Governmental Body against


                                       10
<PAGE>   15


any of the Companies, the Subsidiaries or their respective directors or officers
which could have a Material Adverse Effect on the Companies, either individually
or in the aggregate.

                  3.6 Absence of Undisclosed Liability. None of the Companies
nor any of the Subsidiaries has any material direct or indirect liability,
indebtedness, obligation, expense, claim, deficiency, guarantee or endorsement
of or by any person (other than endorsements of notes, bills and checks
presented to banks for collection deposit in the ordinary course of business) of
any type, whether accrued, absolute, contingent, matured, unmatured or otherwise
(a "Liability"), other than the Liabilities (i) that are reflected, accrued or
reserved for in the most recent quarterly balance sheet of the Issuer filed
pursuant to the Exchange Act with the Commission, or (ii) arising in the
ordinary course of the Companies' or the Subsidiaries' businesses consistent
with past practice which would not result in a Material Adverse Effect on the

evidence reasonably satisfactory to it of the ownership of and the loss, theft,
destruction or mutilation of any certificate or instrument evidencing any of the

parties hereto acknowledge and agree that the numbers of shares of Series Z
Preferred Stock and Common Stock of Issuer to be issued to Holdings and JEDI in
the Exchange have been agreed to by Holdings and JEDI based upon certain
understandings and agreements that such shares would represent certain
percentages of the fully diluted ownership of the Series Z Preferred Stock and
Common Stock of the Issuer which percentages would change if any of the options
or warrants listed on Schedule 8.12 (individually, a "Schedule 8.12 Option" and
collectively, the "Schedule 8.12 Options") are exercised. In consideration of
the agreement of Holdings and JEDI not to require an increase in the number of
shares of Series Z Preferred Stock and Common Stock to be


                                       24
<PAGE>   29


issued in the Exchange, the parties hereto agree that if at any time any
Schedule 8.12 Option is exercised by the holder thereof (an "Exercised 8.12
Option"), then within twenty (20) days after the date notice of such exercise is
received by the Issuer, the Issuer shall issue to Holdings and JEDI options to
purchase shares of Common Stock in the form attached hereto as Exhibit I (the
"Purchaser Adjustment Options") having the same per share exercise price and
termination date as the Exercised 8.12 Option, except that (a) the Purchaser
Adjustment Option issued to Holdings shall be for a number of shares equal to
200% of the number of shares issued with respect to the Exercised 8.12 Option,
(b) the Purchaser Adjustment Option issued to JEDI shall be for a number of
shares equal to 33.33% (rounding to the nearest whole number of shares) of the
number of shares issued with respect to the Exercised 8.12 Option, and (c) the
Purchaser Adjustment Options shall have a minimum term of not less than sixty
(60) days. In the event that any Schedule 8.12 Option is hereafter amended or
otherwise modified, then the Purchaser Adjustment Options issuable upon the
exercise thereof shall be similarly amended or modified; provided, that no
amendments to the Schedule 8.12 Options or the Purchaser Adjustment Options may
be made as to per share exercise price or shares issuable upon conversion
thereof. In addition, the voluntary cancellation or termination of any Schedule
8.12 Option either concurrently with or substantially contemporaneously with the
issuance to the holders of such cancelled or terminated Schedule 8.12 Options of
new options or rights to purchase securities of Issuer hereafter approved by the
Issuer's Board shall not be deemed or construed to be an amendment or
modification of the Schedule 8.12 Options for purposes of this section.

                  8.13 Bank Compliance Certificates. The Companies shall deliver
to Purchasers at the same time as the Companies deliver to the agent under the
Credit Agreement or the agent under any replacement credit agreement all
compliance certificates pursuant to Section 6.13 of the Credit Agreement
delivered to the agent under the Credit Agreement and any other similar notices
or reports pursuant to the Credit Agreement or a replacement credit agreement.

                  8.14 Management Controls. The failure by the Issuer to comply
with any of the covenants set forth below, unless specifically waived in writing
by Holdings, shall entitle Holdings to a right to specific performance, other
equitable remedies or damages available under applicable law. The holders of the
Series E Preferred Stock shall have no rights or remedies under this Section
8.14 other than the right to receive copies of the Annual Budget Plan, Approved
Annual Budget, Updated Budget and Approved Updated Budget pursuant to
subsections (a) and (b) hereof.

                  (a) The Issuer hereby agrees that, so long as Holdings
controls or holds Series D Preferred Stock with a liquidation preference of $25
million or more, the Issuer shall within thirty (30) days prior to the fiscal
year end deliver to Holdings, a proposed detailed budget plan (the "Annual
Budget Plan"), on both a consolidated and consolidating basis, for the
operations of the Companies and the Subsidiaries for the next fiscal year,
prepared by the Issuer's officers and employees and certified by the chief
financial officer of the Issuer, which Holdings shall have the right, in its
sole discretion to approve, modify or disapprove in whole or in part, including
on a "line item" basis. Any Annual Budget Plan (or any portion thereof) approved
in writing by Holdings is herein referred to as an "Approved Annual Budget". A
copy of the Annual Budget Plan and the Approved Annual Budget shall be provided
to holders of the Series E Preferred Stock holding in excess of 49% of the
outstanding Series E Preferred Stock, unless such holders request not to receive

Issuer's officers and employees and certified by the chief financial officer of
the Issuer, which Holdings shall have the right, in its sole discretion to

basis. Any Updated Budget (or any items therein or portion thereof) approved in
writing by Holdings is herein referred to as an "Approved Updated Budget" and
together with the Approved Annual Budget, the "Approved Budgets." A copy of the
Updated Budget and the Approved Updated Budget shall be provided to the holders
of the Series E Preferred Stock holding in excess of 49% of the outstanding
Series E Preferred Stock, unless such holders request not to receive copies of
such budgets. No actions on the part of the Issuer's Board or its officers or
employees shall be permitted without prior approval of Holdings after June 30 of
each year for which an Updated Budget for such year has not been approved (until
such time as an Updated Budget for such year has been approved in accordance
herewith).

                  (c) The Issuer hereby agrees that, so long as Holdings
controls or holds Series D Preferred Stock with a liquidation preference of $25
million, without the prior written approval of Holdings, the Issuer shall not,

                  provided, however, that nothing in this Section 8.14 shall be
                  construed to require the approval of Holdings for, or
                  otherwise render invalid, any action by any Company, taken or
                  directed by an officer or other employee of any Company in
                  good faith in or in response to explosion, fire, flood or
                  other emergency or exigent circumstances to prevent loss of
                  life or injury to persons or property or to comply with
                  applicable governmental or regulatory requirements including
                  without limitation Environmental Laws, but the Companies
                  shall, as promptly as possible, report such emergency or
                  exigent circumstances and the actions taken with respect
                  thereto to Holdings.

                  SECTION 9. INDEMNITY. The Companies jointly and severally
agree to indemnify each Indemnified 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 Indemnified Party growing out of,
resulting from or in any other way associated with this Agreement, the Exchange
or any of 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 Related Person or
any liabilities or duties of any Related Person or of any Indemnified Party 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 WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART,
UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR ARE IN ANY EXTENT CAUSED, IN
WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY
INDEMNIFIED PARTY,

provided only that no Indemnified 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. As used in this section the term
"Indemnified Party" refers to each of Fund V, Portfolio, TCW Asset Management
Company, a California corporation, Trust Company of the West, a California trust
company, Holdings, JEDI (and each of their affiliates) and each director,
officer, agent,

trustee, manager, member, partner, shareholder, principal, attorney, employee,
representative and affiliate of any such Person.


                  SECTION 10. MISCELLANEOUS

                  10.1 Notices.

                  (a) All communications under this Agreement shall be in
writing and shall be effective (a) upon hand delivery or delivery by telecopy or
facsimile, if delivered on a business day during normal business hours where
such notice is to be received or the first business day following such delivery
if delivered other than on a business day during normal business hours where
such notice is to be received or (b) on the second business day following the
date of mailing by first class mail, postage prepaid or by express courier
service, fully prepaid or upon actual receipt of such mailing, whichever shall
first occur:

                           (i) if to any party hereto, at its address for
                  notices specified beneath its name on the signature page
                  hereof, or at such other address as it may have furnished in
                  writing to the Issuer, or

                           (ii) if to any other Person who is the registered
                  holder of any New Securities, to the address for the purpose
                  of such holder as it appears in the stock ledger of the
                  Issuer.

                  10.2 Survival. All representations and warranties and
covenants made by the Companies herein or in any certificate or other instrument
delivered by them or on their behalf under this Agreement shall be considered to
have been relied upon by TCW and the Purchasers and shall survive the issuance
of the New Securities regardless of any investigation made by or on behalf of
TCW and/or the Purchasers.

                  10.3 Successors and Assigns. Except as otherwise expressly
provided herein, this Agreement shall inure to the benefit of and be binding
upon the successors and assigns of each of the parties whether so expressed or
not; provided, that the benefits of Section 8 shall inure to the benefit of
affiliates of the Purchasers or their transferees holding the Requisite
Ownership.

                  10.4 Amendment and Waiver, etc. This Agreement may be amended,
but only with the written consent of each of the Companies, TCW and the
Purchasers. No failure or delay on the part of any of TCW, the Purchasers or the
Companies in exercising any right, power or remedy hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise thereof or the exercise
of any other right, power or remedy. The remedies provided for herein are
cumulative and are not exclusive of any remedies that may be available to TCW
and/or the Purchasers at law or in equity or otherwise. No waiver of or consent
to any departure by the Companies from any provision of this Agreement shall be
effective unless signed in writing by each of the Purchasers who then holds
either five percent (5%) of the outstanding Common Stock and Series Z Preferred
Stock or any Series D Preferred Stock or Series E Preferred Stock.

                  10.5 Counterparts. Two or more duplicate originals of this
Agreement may be signed by the parties, each of which shall be an original but
all of which together shall constitute one and the same instrument.

                  10.6 Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

                  10.7 Governing Law. This Agreement shall be construed in
accordance with and governed by the law of the State of New York as applicable
to contracts.

                  10.8 Expenses. Whether or not the transactions contemplated by
this Agreement close, the 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 instruments evidencing the New Securities, (c) relating to any
amendments, waivers or consents under this Agreement to the same extent as set
forth in clause (a) and (b) above incident to the enforcement by the Purchasers
of, or the protection or preservation of any right or remedy of the Purchasers
under, this Agreement, or any other document or agreement furnished pursuant
hereto or thereto or in connection herewith or therewith (including, without
limitation, reasonable fees and expenses of counsel), (d) relating to third
party engineering and outside accounting costs, and (e) relating to any future
dealings associated with the transactions relating to this Agreement and the
Exchange (including any engineering, legal, and outside accounting costs). The
Companies shall pay such costs and expenses, to the extent then payable, on the
date of issuance of the New Securities or, with respect to those matters
described in clauses (b), (c), (d) and (e) above thereafter from time to time
upon demand by the Purchasers upon presentation, in each such case, of a
statement thereof. Additionally, the Companies shall pay an additional $25,000
to each of TCW and JEDI (in addition to any payments made for each party's costs
and expenses as set forth herein) at Closing.

                  10.9 Specific Performance. The Companies recognize that money
damages may be inadequate to compensate 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.

                  10.10 Arbitration. 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.


                                       29
<PAGE>   34


                  (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 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.

                  "Register," "registered" and "registration" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Securities Act and the declaration or ordering of
effectiveness of such registration statement.

                  "Registrable Common Stock" means, collectively, (a) the shares
of Common Stock issued to JEDI and Holdings pursuant to the Exchange Agreement,
(b) the shares of Common Stock acquirable upon the conversion of the Series Z
Preferred Stock issued to Holdings pursuant to the Exchange Agreement, (c) the
shares of Common Stock issuable upon exercise of any of the Purchaser Adjustment
Options, (d) the shares of Common Stock held by the Smith Group as of the date
hereof and (e) any shares of Common Stock or other securities issued with
respect to the Common Stock described in clauses (a), (b), (c) and (d) of this
definition whether by way of stock dividend or stock split or in connection with
a combination of shares, recapitalization, merger, consolidation, share
exchange, reorganization or otherwise held by Holdings, JEDI or the Smith Group;
provided, however, such Common Stock or other securities shall cease to be
Registrable Common Stock when (i) a registration statement with respect to the
disposition of such Common Stock or other securities shall have become effective
under the Securities Act and such securities shall have been disposed of in
accordance with the plan of distribution set forth in such registration
statement, (ii) such Common Stock or other securities shall have been sold
pursuant to Rule 144 (or any successor provision) under the Securities Act,
(iii) such Common Stock or other securities shall have ceased to be outstanding
or (vi) such Common Stock or other securities may be sold pursuant to Rule 144
(or a successor provision) under the Securities Act without being restricted by
the volume limitations or method of sale restrictions thereof.

                  "Securities Act" means the Securities Act of 1933, as amended,
and the rules and regulations promulgated thereunder.

                  "Series Z Preferred Stock" means the Series Z Convertible

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
Registrable Common Stock to be registered, will specify the intended methods of
disposition thereof and will specify whether the registration statement to be
filed is a "shelf" registration statement ("Shelf Registration Statement")
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.

                  (b) Number of Demand Registrations; Effective Registration;
Expenses. So long as (i) Holdings holds Registrable Common Stock, it (and its
transferees), shall be entitled to initiate and have effected an aggregate of
three (3) Demand Registrations; (ii) JEDI holds Registrable Common Stock, it
(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 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 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
such registration under this Agreement or under any registration rights
agreement in effect on the date hereof and (iii) third, the Common Stock
requested to be included in such registration by the holders thereof entitled to
participate in such registration under a registration rights agreement effective
after the date hereof and (B) if such registration was initiated as the result
of the exercise of a demand registration right of holders of Common Stock (i)
first, the shares of Common Stock requested to be included in such registration
by the demanding holders pro rata among those requesting such registration on
the basis of the number of shares of Common Stock requested to be included),
(ii) second, shares to be issued and sold by the Company and shares held by
Persons other than the demanding holders and requested to be included in such
registration either pursuant to this Agreement or pursuant to any registration
rights agreement in effect on the date hereof and (iii) third, the Common Stock
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 (A)(ii) or (B)(ii)
above, the allocation shall be made pro rata based on the 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 pursuant to clause
(A)(iii) or (B)(iii) above, the allocation shall be made pro rata based on the
number of shares of Common Stock that each shall such participant shall have
requested to include therein.

                  (b) The holders of Registrable Common Stock to be distributed
by such underwriters shall be parties to the underwriting agreement between the
Company and such underwriters. The representations and warranties by, and the
other agreements on the part of, the Company to and for the benefit of such
underwriters shall also be made to and for the benefit of the holders of
Registrable Common Stock to be distributed by such underwriters, and the
conditions precedent to the obligations of such holders of Registrable Common
Stock under such underwriting


                                       4

agreement shall be reasonably satisfactory to such holders. Such holders shall
not be required to make any representations or warranties to the Company or its
underwriters other than representations or warranties regarding such holder,
such holder's interest in the shares to be distributed and such holder's
intended method of distribution. The Company 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


                                       5
<PAGE>   8


                  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 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


                                       6
<PAGE>   9


                  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
                  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;

                  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

                  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

<PAGE>   10


                  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;

                      (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

                  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

                  (a) Indemnification by the Company. The Company agrees to
indemnify and hold harmless each holder of Registrable Common Stock, its

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,

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

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 indemnification 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 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 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


                                       11
<PAGE>   14


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 the Company, Holdings,
JEDI and the Smith Group; provided, however, at such time as any of Holdings,
JEDI or any member of the Smith Group no longer holds Registrable Common Stock,
this Agreement (other than Section 8) may be amended, modified or supplemented
without consent of the party no longer holding Registrable Common Stock.

                  Section 13. Notices. All communications under this Agreement
shall be in writing and shall be effective (a) upon hand delivery or delivery by
telecopy or facsimile, if delivered on a business day during normal business
hours where such notice is to be received or the first business day following
such delivery if delivered other than on a business day during normal business
hours where such notice is to be received or (b) on the second business day
following the date of mailing by first class mail, postage prepaid or by express
courier service, fully prepaid, or upon actual receipt of such mailing,
whichever shall first occur:

                         (i) if to a holder of Registrable Common Stock at the
                  most current address given by such holder to the Company in
                  writing;

                         (ii) if to the Company at its address set forth in the
                  Exchange Agreement.

                  Section 14. Counterparts. This Agreement may be executed in
any number of counterparts and by the parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and all of
which taken together shall constitute one and the same agreement.

                  Section 15. Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  Section 16. Governing Law. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York.

                  Section 17. Severability. In the event that any one or more of
the provisions contained herein, or the application thereof in any
circumstances, is held invalid, illegal or unenforceable in any respect for any
reason, the validity, legality and enforceability of any such provision in every
other respect and of the remaining provisions contained herein shall not be in
any way impaired thereby, it being intended that all of the rights and
privileges of the parties hereto shall be enforceable to the fullest extent
permitted by law.

                  SECTION 3. TAGALONG RIGHTS

                  3.1 If Holdings or any affiliate thereof ("Transferor")
transfers, 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 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 Transaction"), then each of the Smith Group and JEDI (each a "Tagalong
Party," 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). Each Tagalong Party


                                       4
<PAGE>   5


shall only be entitled to sell shares of Common Stock under this Section 3 that
it 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.



                                       5
<PAGE>   6

                  4.2 If any of the Drag-Along Parties proposes to Transfer to
any of its affiliates 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>   7


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).

affiliate transferees of Holdings' securities acquired under the Exchange
Agreement) endeavor to purchase shares of Common Stock from any Person not a

<PAGE>   9

Group and JEDI equal in aggregate amount to the amount Holdings, Fund V or
Portfolio endeavor to purchase or the total number of shares of Common Stock
then held by members of the Smith Group and JEDI, whichever is less, based on

                  SECTION 9. MISCELLANEOUS

                  9.1 Successors and Assigns; Termination. Except as otherwise
expressly provided herein, this Agreement shall inure to the benefit of and be
binding upon the permitted successors and assigns of the parties hereto;
provided, however, as to any particular Securities, this Agreement shall
terminate and not apply when such Securities are no longer held by any members
of the Smith Group, the Purchasers or their respective affiliates; provided
further that the provisions of Section 5.2 shall apply to Securities until all
outstanding Series Z Preferred Stock is converted to Common Stock; and provided
further, that the provisions of Section 8 shall apply to Holdings, Fund V and
Portfolio regardless of their holdings of Securities. Nothing herein shall be
construed to prohibit any future holder of the Securities from assuming the
rights and obligations under this Agreement.

                  9.2 Amendment and Waiver, etc. 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 shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right, power or remedy preclude
any other or further exercise thereof or the exercise of any other right, power
or remedy. The remedies provided for herein are cumulative and are not exclusive
of any remedies that may be available to the parties at law or in equity or
otherwise.

                  9.3 Counterparts. Two or more duplicate originals of this
Agreement may be signed by the parties, each of which shall be an original but
all of which together shall constitute one and the same instrument.

enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

                  9.5 Specific Performance. The parties recognize that money
damages may be inadequate to compensate for a breach of the obligations
hereunder, and irrevocably agree that the remedy of specific performance or the
granting of such other equitable remedies as may be appropriate may be granted
in order to afford the parties the benefits of this Agreement and the


                                       9
<PAGE>   10

parties shall not object and waive any right to object to such remedies on the
grounds that money damages will not be sufficient to compensate for a breach
hereof.

                  9.6 Notices. All communications under this Agreement shall be
in writing and shall be effective (a) upon hand delivery or delivery by telecopy
or facsimile, if delivered on a business day during normal business hours where
such notice is to be received or (b) on the second business day following the
date of mailing by first class mail, postage prepaid or by express or courier

                  other address as it may have furnished in writing to the
                  Issuer; or

         (ii)     if to any other Person who is the registered holder of any
                  Preferred Stock, to the address for the purpose of such holder
                  as it appears in the stock ledger of the Issuer.

                  9.7 Governing Law. This Agreement shall be construed in
accordance with and governed by the law of the State of Washington.
