I.       INTRODUCTION

         A.       Preliminary Statement

                  On the Petition Date, CellNet Data Systems, Inc. (the
"Parent") and its subsidiaries filed separate voluntary petitions for relief
under chapter 11 of the Bankruptcy Code (the "Cases"). This Disclosure
Statement and the accompanying Plan relate to all of the companies listed on
the signature page (collectively with Parent, the "Debtors").1 The Cases are
being jointly administered, with the Debtors managing their businesses and
affairs as debtors in possession, subject to the control and supervision of
the Court. On February 15, 2000, the United States Trustee for the District
of Delaware (the "United States Trustee") appointed the Creditors' Committee.
The Plan contemplates the substantive consolidation of the Debtors.

                  The Debtors submit this Disclosure Statement pursuant to
section 1125 of the Bankruptcy Code in connection with the solicitation of
acceptances of the Plan, a copy of which is annexed hereto as Exhibit A.

                  The Bankruptcy Court has approved this Disclosure Statement
as containing "adequate information" in accordance with section 1125(b) of
the Bankruptcy Code to enable a hypothetical, reasonable investor in each of
the relevant Classes to make an informed judgment about the Plan.

         C.       Purpose of this Disclosure Statement

                  The purpose of this Disclosure Statement is to provide holders
of Claims with such information as would enable a hypothetical, reasonable
individual or entity typical of the holders of Claims and Interests to make an
informed judgment related to voting on the Plan. This Disclosure Statement does

the Debtors, the applicable provisions of the Bankruptcy Code, or of other
matters that may be deemed significant by creditors or other parties in
interest. For further information you should examine the Plan directly, you may
want to consult your own legal and financial advisors,


                                      3

and you may want to examine the documents that the Parent has previously
filed with the Securities and Exchange Commission.

                  You are urged to read carefully the contents of this
Disclosure Statement and the Plan before making your decision to accept or
reject the Plan. Particular attention should be directed to the provisions of
the Plan affecting or impairing your rights as they existed before the
institution of the Debtors' Cases.

                  NO REPRESENTATIONS CONCERNING THE DEBTORS OR THE PLAN ARE
AUTHORIZED EXCEPT AS SET FORTH IN THIS DISCLOSURE STATEMENT. IN DECIDING TO
ACCEPT THE PLAN YOU SHOULD NOT RELY UPON ANY REPRESENTATIONS OF THE DEBTORS OR
ANY OTHER PARTY OTHER THAN THOSE IN THIS DISCLOSURE STATEMENT.

Section XI herein for the discussion of Voting Procedures.

                  5.       Ballot Calculations

                  In order for the Plan to be accepted by any class of
creditors, it must be accepted by creditors who hold at least two-thirds in
dollar amount of the Claims of such class to which votes are cast and who
comprise more then one-half of the voting creditors holding Claims of such
class. THESE CALCULATIONS ARE BASED ONLY ON THE CLAIM AMOUNTS AND NUMBER OF
CREDITORS WHO ACTUALLY VOTE. ANY BALLOT THAT IS VALIDLY EXECUTED THAT DOES NOT
CLEARLY INDICATE REJECTION OF THE PLAN SHALL BE DEEMED TO CONSTITUTE A VOTE FOR
ACCEPTANCE OF THE PLAN. THE VOTE OF EACH CREDITOR IS IMPORTANT. The Ballot Agent
will prepare and file with the Court a certification of the results of the
balloting with respect to the Plan.

II.      BACKGROUND

         A.       Debtors' Business

                  The Debtors designed, developed, marketed, deployed and
operated wireless communications networks capable of monitoring millions of
fixed endpoints. The primary commercial application of these networks has been
to provide commercial, industrial and residential network meter reading services
to electric, gas and water utility companies. The Debtors had contracts for the
installation of networks to monitor more than 7 million utility meters.


                                      6
<PAGE>

                  CellNet's business model projected substantial growth but
required substantial additional capital to finance that growth. The Debtors
estimated they needed at least $150,000,000 to $200,000,000 in additional equity
capital immediately and over the next several years at least $400,000,000 to
$500,000,000 in project finance would be also required. In the several months
preceding the filing of these Cases, the Debtors generated consistent negative
cash flow of approximately $10,000,000 per month.

         B.       Unsuccessful Search for Capital

                  In an effort to raise additional equity capital, the Parent
engaged Morgan Stanley Dean Witter ("MSDW") as its investment banker. Beginning
in the first quarter of 1999, the Parent and MSDW furnished information to more
than 90 potential financial and strategic investors and worked with a number of
such parties in significant detail in order to develop their interest further.
The amount of capital needed, the amount of leverage in the Debtors' existing
capital structure and investor uncertainty concerning the future pace of market
acceptance for the Debtors' utility meter reading and other services, among
other things, made it difficult to raise the equity capital required. After
extensive efforts, including detailed negotiations with several parties, MSDW
and the Parent concluded, in September 1999, that they could not arrange the
necessary financing without a financial restructuring. The Parent then retained
The Blackstone Group L.P. ("Blackstone") for this purpose. Blackstone
immediately began to solicit potential lenders and investors in order to secure
both the short-term funding required to maintain current operations and the
long-term capital required to fund growth over the next several years.
Blackstone contacted more than 60 potential investors in this effort. In spite
of the fact that the Debtors' financial structure could be transformed through a
chapter 11 reorganization, potential investors continued to be deterred by the
magnitude of capital required to bring the Debtors to the point that they could
fund their own operations. After an exhaustive search for additional capital
over nearly a year, the Debtors ultimately concluded that they could not attract
sufficient capital to finance a feasible stand-alone reorganization.

                  Prepetition, the Debtors and Blackstone successfully convinced
two existing constituencies to participate in resolving the Debtors' financial
needs. First, holders ("Noteholder Group") of approximately two-thirds in
principal amount of the Parent's unsecured 14% Senior Discount Notes due 2007
(the "Senior Discount Notes"), provided $22,200,000 in additional short-term
funding on a secured basis.

                  Secondly, Schlumberger Resource Management Services, Inc.
("Schlumberger"), a wholly owned subsidiary of Schlumberger, Ltd. and a
strategic partner with the Debtors in a contract to provide automated meter
reading services to PECO Energy Company, expressed an interest in providing a
portion of the additional long-term capital needed by the Debtors. In December,
1999, the Debtors began negotiations with these parties, yet were unable to
negotiate a long-term financing arrangement. By January, 2000, the Debtors
recognized that recapitalization and reorganization were unlikely given the
responses received from potential investors. Recognizing the possibility that
the sale of substantially all of their assets on a going concern would provide a
greater return to their creditors than a liquidation, the Debtors began
negotiating directly with Schlumberger to sell the Debtors' business to
Schlumberger.


                                      7
<PAGE>

                  In the weeks preceding the petition date, the Debtors
negotiated with Schlumberger to obtain postpetition financing and to finalize
the terms of the asset sale. Immediately prior to filing the Cases, the terms of
postpetition financing were finalized and the Debtors executed a summary of
terms (the "Term Sheet") with Schlumberger for the sale of substantially all of
the Debtors' assets.

         C.       Filing of the Debtors' Cases

                  On February 4, 2000, each of the Debtors filed with the
Bankruptcy Court a voluntary petition for relief under chapter 11 of the
Bankruptcy Code. Pursuant to an order of the Bankruptcy Court, these Cases were
consolidated for procedural purposes only and are being jointly administered.

                  On February 15, 2000, pursuant to sections 1102(a) and (b) of
the Bankruptcy Code, the United States Trustee appointed the Creditors'
Committee, comprised of: (i) HSBC Bank USA, as indenture trustee for holders of
the Senior Discount Notes (the "Indenture Trustee"); (ii) Victron, Inc.; and
(iii) Volt Viewtek, Inc. On February 18, 2000, Volt Viewtek, Inc. resigned from
the Creditors' Committee and General Dynamics Government Systems Corporation
became a member of the Creditors' Committee.

                  The Creditors' Committee retained Pryor Cashman Sherman &
Flynn LLP as its counsel, Connolly, Bove, Lodge & Hutz as Delaware counsel and
Crossroads LLC as its financial advisor.

         D.       Debtor-in-Possession Financing

                  Pursuant to a February 24, 2000 order entitled Final Order
(i) Authorizing Secured Postpetition Financing Pursuant To 11 U.S.C. section
364(C) And (D), (ii) Authorizing Use Of Cash Collateral Pursuant To 11 U.S.C.
section 363 and (iii) Granting Adequate Protection Pursuant To 11 U.S.C.
sections 361, 363, and 364, Schlumberger Technology Corporation (the
"Lender"), a subsidiary of Schlumberger, Ltd., agreed to provide
post-petition financing to the Debtors pursuant to the Post-Petition Credit
Agreement, dated as of February 4, 2000 (as amended, supplemented or
otherwise modified, the "DIP Agreement"). The DIP Agreement provided the
Debtors with sufficient funds to continue the Debtors' operations in the
ordinary course. By the terms of the DIP Agreement, the Lender forgave all of
the Debtors' obligations arising under the postpetition financing upon the
consummation of the Sale (defined herein).

         E.       Postpetition Sale Efforts

                  The Debtors and Schlumberger continued to negotiate the terms
of the asset sale throughout February, 2000. Consistent with the Term Sheet and
in contemplation of executing an asset purchase agreement, the Debtors submitted
a motion to the Bankruptcy Court seeking to grant certain bid protections to
Schlumberger and to establish competing bid procedures. The Asset Purchase
Agreement was finalized and executed on March 1, 2000 and the Bankruptcy Court
entered an order approving the bid protections and procedures on March 9, 2000.
While the Debtors were permitted to, and did, solicit competing bids, including
bids to fund a plan of


                                      8
<PAGE>

reorganization, no competing bids or recapitalization plans were submitted by
third parties by the deadline established by the Bankruptcy Court, or at any
time thereafter. Ultimately, on May 5, 2000, the Bankruptcy Court entered the
Order Pursuant To Sections 105, 363, 365 And 1146(c) And Fed. R. Bankr. P.
6004 and 6006 (A) Approving Asset Purchase Agreement With Schlumberger
Resource Management Services, Inc., And (B) Authorizing Sale Of Assets And
Assumption And Assignment Of Assumed Leases And Assumed Contracts Free And
Clear Of Liens, Claims, Encumbrances And Interests And Exempt From Any Stamp,
Transfer, Recording Or Similar Tax (the "Sale").

                  The Sale had a transaction value of approximately $235
million, which was composed of (a) a cash payment of $54,941,000; (b) repayment
or assumption of secured debt of approximately $118 million; (c) assumed
liabilities to employees and key vendors of approximately $26 million, and (d)
forgiveness/assumption of post-petition financing, which was approximately $36
million at the Sale closing. The Sale closed on May 16, 2000.

         F.       Post-Sale Assets of the Debtors

                  After the Sale, the Debtors' primary remaining asset is the
Cash received from Schlumberger pursuant to the Sale. Additionally, the Debtors
will realize additional Cash from the following transactions:

                  1.       The Estates will receive at least $2,250,000 and up
                           to $4,500,000 from the sale to Bechtel Enterprises,
                           Inc. of certain remaining assets not purchased by
                           Schlumberger. These assets include (i) the royalty
                           payments payable by BCN Data Systems L.L.C., a joint
                           venture limited liability company in which the Parent
                           and Bechtel Enterprises, Inc. hold equity interests,
                           in connection with the license of intellectual
                           property, and (ii) the Parent's equity interest in
                           the joint venture. On June 26, 2000, the Bankruptcy
                           Court entered an order approving this sale.

                  2.       The Estates may receive additional Cash, on account
                           of the assignment of certain leased property located
                           in San Ramon, California.

                  3.       Following the Sale, certain funds held in escrow for
                           the benefit of the holders of Preferred Stock in
                           CellNet Funding, L.L.C. were distributed to such
                           holders pursuant to a stipulation among the Debtors,
                           the Unofficial Committee of Holders of Preferred
                           Securities and Bank of New York, as Escrow Agent,
                           approved by the Bankruptcy Court on June 13, 2000.
                           Approximately $200,000 of such funds were distributed
                           to the Debtors.

         G.       Status of Claims of Itron, Inc.

                  Itron, Inc. ("Itron") has asserted claims in the U.S. District
Court for the District of Minnesota against the Parent for damages and
injunctive relief based on alleged patent infringement (Case Numbers 99-1500,
-1524). Such court entered a judgment in favor of the


                                      9
<PAGE>

Parent and Itron appealed; the appeal has been briefed and is awaiting oral
argument. The Parent believes the judgment in its favor will be affirmed and
it will not have any liability to Itron.

                  Itron has filed a Claim in these Cases for a contingent and
unliquidated amount based on such litigation, other ancillary costs and
attorneys' fees. The Debtors have objected to Itron's Claim, asserted their
rights of setoff and moved for disallowance of Itron's Claim and estimation of
Itron's Claim at zero for purposes of allowance and distribution. In any event,
the Debtors believe that, even in the event said judgment was reversed and Itron
prevailed, the amount of damages for which the Debtors would be liable is
negligible in light of the small amount of revenues generated by Debtors in the
history of their existence. Itron's request for injunctive relief is believed by
Debtors to be moot since they have stopped using the technology in dispute.
Itron contends that, if it is successful on the merits of its appeal, it would
be entitled to an administrative claim for the period from the petition date to
the date the Debtors sold the technology in question to Schlumberger. The Parent
believes that it will prevail in the appeal and, in any event, that the amount
of revenue generated from use of such technology during the postpetition period
is so small that the amount of such administrative claim would be negligible. If
Debtors were incorrect in the foregoing beliefs, the recovery of unsecured
creditors would be reduced, but not materially.

         H.       Source of Facts Presented Herein

                  The Debtors believe that the facts set forth herein are
accurate as of the date of this Disclosure Statement. These facts were derived
from internal company records, including unaudited financial statements.


III.     SUMMARY OF THE PLAN

         A.       Substantive Consolidation

                  The Plan contemplates entry of the Substantive Consolidation
Order, which will effect the substantive consolidation of the Cases into a
single chapter 11 case. On the Confirmation Date or such other date as may be
set by a Final Order of the Court, but subject to the occurrence of the
Effective Date: (i) all Intercompany Claims by and among the Debtors will be
eliminated; (ii) all assets and liabilities of the Debtors will be merged or
treated as though they were merged; (iii) all prepetition cross-corporate
guarantees of the Debtors will be eliminated; (iv) all Claims based upon
guarantees of collection, payment or performance made by one or more of the
Debtors as to the obligations of another Debtor or of any other Person will be
discharged, released and of no further force and effect; (v) all Interests of
any Debtor in any other Debtor shall be eliminated; and (vi) each and every
Claim filed in the Case of any one Debtor will be deemed filed against the
consolidated Debtors in the consolidated Cases and shall be deemed a single
obligation of all of the Debtors under the Plan on and after the Confirmation
Date.

                  The Plan will serve as a motion seeking entry of an order
substantively consolidating the Reorganization Cases. UNLESS AN OBJECTION TO
SUBSTANTIVE


                                      10
<PAGE>

CONSOLIDATION IS MADE IN WRITING BY ANY CREDITOR AFFECTED BY THE PLAN ON OR
BEFORE FIVE (5) DAYS PRIOR TO THE DATE THAT IS FIXED BY THE COURT AS THE LAST
DATE ON WHICH ACCEPTANCES TO THE PLAN MAY BE RECEIVED, OR SUCH OTHER DATE AS
MAY BE FIXED BY THE COURT, THE SUBSTANTIVE CONSOLIDATION ORDER MAY BE ENTERED
BY THE COURT. In the event any such objections are timely filed, a hearing
with respect thereto shall be scheduled by the Court, which hearing may, but
need not, coincide with the Confirmation Hearing.

                  Substantive consolidation is an equitable remedy which a
bankruptcy court is asked from time to time to apply in cases involving
affiliated debtors. As contrasted with procedural consolidation,2 substantive
consolidation affects the substantive rights and obligations of creditors and
debtors. Substantive consolidation involves the pooling and merging of the
assets and liabilities of the affected debtors; all of the debtors in the
substantively consolidated group are treated as if they were a single
corporate/economic entity. The consolidated assets create a single fund from
which all claims against the consolidated debtors are to be satisfied.
Consequently, a creditor of one of the substantively consolidated debtors is
treated as a creditor of the substantively consolidated group of debtors and
issues of individual corporate ownership of property and individual corporate
liability on obligations are ignored.

                  Section 105 of the Bankruptcy Code provides the basis for the
power to substantively consolidate interrelated chapter 11 cases. Within this
framework of a court exercising its equitable powers, the factors to which
courts have looked to determine the appropriateness of substantive consolidation
include: (a) whether creditors dealt with the debtor entities as a single
economic unit and did not rely on their separate identities in extending credit,
and (b) whether the affairs of the debtors are so entangled that the
consolidation will benefit all creditors of the debtors' estates. Additional
factors include: (i) the presence or absence of consolidated financial
statements; (ii) the existence of inter-company guarantees or loans; (iii) the
unity of interest and ownership between the various corporate entities; (iv) the
transfer of assets without observance of corporate formalities; (v) the degree
of difficulty in segregating and ascertaining individual assets and liabilities;
(vi) the parent, its affiliates and subsidiaries having common directors and/or
officers; (vii) the parent or its affiliates financing one another; and (viii)
the commingling of assets and business functions. Debtors clearly satisfied a
majority of

----------------
2        Procedural consolidation is the administrative process, pursuant to
         Bankruptcy Rule 1015(b), whereby the proceedings of two or more
         affiliated debtors are conducted as part of a single proceeding for the
         convenience of the bankruptcy court and parties in interest. Procedural
         consolidation does not affect the substantive rights of the debtors or
         their respective creditors and interest holders. The Cases were
         procedurally consolidated by order of the Court dated February 4, 2000.


                                      11
<PAGE>

these factors, specifically (i), (ii), (iii), (vi), (vii) and (viii). Courts
have ordered substantive consolidation where the proponents have demonstrated
(x) either a harm to be avoided or (y) a benefit to be effected generally
which, under the circumstances and considering whether the rights of third
parties would be unduly prejudiced thereby, it is equitable to effect.

                  The Debtors believe their creditors treated them as a single
economic unit, relying on consolidated financial information and not their
structurally separate corporate entities in determining their creditworthiness
and extending credit. The Debtors further believe that substantive consolidation
of the Estates will facilitate the implementation of the Plan, enabling the
Debtors to treat holders of Claims with greater similarity and fairness and save
administrative costs by simplifying administration of the remaining assets and
liabilities. The Debtors believe that, in addition to being justified pursuant
to applicable law, substantive consolidation is in the best interests of their
creditors. The Debtors' analysis, which will be introduced at the Confirmation
Hearing, shows that the recovery of virtually all creditors will be higher or
approximately equal, under the Plan, as it would be if there were no substantive
consolidation. The vast majority of Debtors' creditors are creditors of the
parent, CellNet Data Systems, Inc. and their recovery will be at least equal, if
not greater, under substantive consolidation as under a non-substantive
consolidation plan.

         B.       Objections to Claims

                  Any Claim not deemed filed pursuant to section 1111(a) of the
Bankruptcy Code or filed on or before the earlier of the Confirmation Date or
the time fixed by the Bankruptcy Court for filing such Claims, or as otherwise
provided herein, will be disallowed, expunged, and discharged.

         C.       Claims Resolution

                  The Debtors will be responsible for scheduling Disputed
Claims. Unless an objection is filed, the Confirmation Order will approve the
Estimated Allowed Claim Schedule, thus making such Claims Allowed at their
scheduled amount.

         D.       Distributions

                  The Debtors will distribute Cash from the Distribution Account
to holders of Allowed Class 3 Claims. The Debtors have established a nominal
threshold distribution level for individual Class 3 creditors and will not make
such Distributions in an amount less than $50.00. Funds that otherwise would
have been distributed in amounts less than $50.00 will be included in the Final
Distribution to holders of Allowed Class 3 Claims.

         E.       Liquidation of the Debtors

                  The Plan is a liquidating plan of reorganization. However,
while the Debtors have ceased to operate as a provider of services for their
customers following the Asset Purchase


                                      12
<PAGE>

Agreement, the Parent will continue to exist to consummate the Plan and
perform the other tasks and functions described therein.

         F.       Management of the Debtors

                  As of the Effective Date, the Debtors, other than Parent, will
dissolve pursuant to applicable state law. The Chief Operating Officer of the
Parent, John S. Dubel, and the Vice President and Secretary, David L. Perry,
will remain as officers and directors of the Debtors. The Chief Operating
Officer, and the Vice President and Secretary, at the direction of the Chief
Operating Officer, will be responsible for carrying out the provisions of the
Plan.

         G.       Treatment of Officers, Directors and Chief Operating Officer

                  With the exception of the Officers, the authority, power and
incumbency of the persons then acting as officers and directors of the Debtors
shall be terminated on the Effective Date and such officers and directors shall
be deemed to have resigned. The Plan will be administered and actions will be
taken in the name of the Debtors through the Chief Operating Officer. The Chief
Operating Officer will, among other things, manage the Debtors and administer
the wind-down of the Debtors' affairs, make all Distributions required to be
made under the Plan and facilitate the Debtors' holding of any undistributed
funds, pending distribution to creditors pursuant to the Plan, and direct the
Vice President and Secretary regarding the implementation of the Plan's
provisions.

         H.       Dissolution of Creditors' Committee

                  The Creditors' Committee will continue in existence until the
Effective Date, at which time the Creditors' Committee will dissolve and, except
for the limited purpose of filing necessary fee applications with the Bankruptcy
Court, its members deemed released of their duties, responsibilities and
obligations in connection with the Debtors' Cases or the Plan.

         I.       Cancellation of Notes/Stock/Instruments/Agreements

                  All Common Stock, Preferred Stock and other ownership
interests of any of the Debtors and all Senior Discount Notes, notes, bonds,
indentures, agreements, contracts or other instruments or documents evidencing
or creating any indebtedness, obligation or liability of any of the Debtors
shall be deemed canceled on the Effective Date and shall have no force and
effect against the Debtors, in each case except for the purpose of evidencing
the right to participate in the Distributions contemplated by the Plan.

         J.       Condition to Effectiveness

                  The following are conditions which must occur for the Plan to
become effective:

                  1.       the Bankruptcy Court has entered the Confirmation
                           Order and more than ten (10) days have elapsed since
                           the Confirmation Date, no stay of the


                                      13
<PAGE>

                           Confirmation Order is in effect and the Confirmation
                           Order has not been reversed, modified or vacated, and

                  2. the Operating Account and the Distribution Account have
been established by the Debtors.

         K.       Executory Contracts and Unexpired Leases

                  Effective as of the Confirmation Date, each executory contract
and unexpired lease that has not been assumed or rejected by the Debtors as of,
or prior to, the Confirmation Date with the approval of the Bankruptcy Court, if
any, will be deemed rejected pursuant to sections 365 and 1123 of the Bankruptcy
Code. Each entity that is a party to an executory contract or unexpired lease
rejected pursuant to the Plan (and only such entities) will be entitled to file,
not later than thirty (30) days following the Confirmation Date, a proof of
claim for damages alleged to have been suffered due to such rejection; provided,
however, that the opportunity afforded an entity whose executory contract or
unexpired lease is rejected pursuant to the Plan to file a proof of claim on or
before such date shall in no way apply to entities who may assert a claim on
account of an executory contract or unexpired lease that was previously rejected
by the Debtors for which a prior bar date was established. Any person or entity
that has a claim for damages as a result of the rejection of an executory
contract or unexpired lease pursuant to the terms of the Plan that does not file
a proof of claim in accordance with the terms and provisions of the Plan will be
forever barred from asserting that claim against any of the Debtors or any
property of the Estates.

         L.       Injunction

                  The Confirmation Order will provide, among other things, that
from and after the Confirmation Date, any holder of a Claim or Interest, any
trustee for any such holder, or any other party in interest, or any of their
respective agents, employees, representatives, financial advisors or attorneys,
or any of their successors or assigns are permanently enjoined from taking any
of the following actions against the Debtors, the Creditors' Committee, any of
their respective present or former members, directors, officers, employees,
advisors, attorneys or agents, for any act or omission in connection with,
relating to, or arising out of the Cases, the pursuit of confirmation of this
Plan, or the consummation of the Plan, except for their willful misconduct or
gross negligence: (a) commencing, conducting or continuing in any manner,
directly or indirectly, any suit, action or other proceeding of any kind
(including, without limitation, any proceeding in a judicial, arbitral,
administrative or other forum) (other than actions to enforce any rights or
obligations under the Plan); (b) enforcing, levying, attaching (including,
without limitation, any pre-judgment attachment), collecting or otherwise
recovering by any manner or means, whether directly or indirectly, any judgment,
award, decree or order; (c) creating, perfecting or otherwise enforcing in any
manner, directly or indirectly, any encumbrance of any kind; (d) asserting any
right of setoff of any kind, directly or indirectly; (e) acting or proceeding in
any manner, in any place whatsoever, that does not conform to or comply with the
provisions of the Plan; and (f) prosecuting or otherwise asserting any right,
claim or cause of action released pursuant to the Plan.


                                      14
<PAGE>

         M.       Exculpation

                  Except with respect to the express duties provided in the
Plan, none of the Debtors, the Creditors' Committee, or any of their respective
present or former members, directors, officers, employees, advisors, attorneys,
affiliates, subsidiaries or agents, shall have or incur any liability to any
holder of a Claim or Interest, or any other party in interest, or any of their
respective agents, employees, representatives, financial advisors or attorneys,
or any of their successors or assigns, for any act or omission in connection
with, relating to, or arising out of these Cases, the pursuit of confirmation of
the Plan, or the consummation of the Plan, except for their willful misconduct
or gross negligence, and in all respects shall be entitled to reasonably rely
upon the advice of counsel with respect to their duties and responsibilities
under the Plan or in the context of these Cases. Except with respect to the
express duties provided in the Plan, no holder of a Claim or Interest, or any
other party in interest, including their respective agents, employees,
representatives, financial advisors, or attorneys, shall have any right of
action against the Debtors, the Creditors' Committee, or any of their respective
present or former members, directors, officers, employees, advisors, attorneys,
affiliates, subsidiaries or agents, for any act or omission in connection with,
relating to, or arising out of, these Cases, the pursuit of confirmation of the
Plan, the consummation of the Plan or the administration of the Plan, except for
their willful misconduct or gross negligence.

         N.       Retention of Jurisdiction

                  The Bankruptcy Court will retain jurisdiction over the Cases,
pursuant to and for the purposes of sections 105(a) and 1127 of the Bankruptcy
Code, and all matters arising out of or relating to the Cases.


IV.      CLASSIFICATION AND TREATMENT OF CLAIMS

         A.       Administrative Claims

                  An Administrative Claim is a claim under section 503(b) of the
Bankruptcy Code that is entitled to priority under section 507(a)(1) of the
Bankruptcy Code for costs or expenses of administration of the Cases including,
without limitation, any actual and necessary expenses of preserving the estates
of the Debtors, any actual and necessary expenses of operating the business of
the Debtors, any indebtedness or obligations incurred or assumed by the Debtors
as debtors in possession in connection with their conduct of the businesses of
the Debtors, and all compensation or reimbursement of expenses of professionals
within the meaning of sections 327 and 1103 of the Bankruptcy Code to the extent
allowed by the Bankruptcy Court. Administrative Claims also include professional
fees and expenses that are accrued but unpaid as of the Effective Date.

                  Under the Plan, the Debtors will make a Distribution in an
amount equal to the amount of the Allowed Administrative Claim to each holder of
an Allowed Administrative Claim, if any. Such payment will be made on the First
Distribution Date or on the fifteenth (15th) day after such later date that such
Claim becomes an Allowed Administrative Claim, unless the holder shall


                                      15
<PAGE>

have agreed to different treatment of such Claim. The Debtors estimate that
Allowed Administrative Claims will approximate less than $1,000,000
(exclusive of professional fees and expenses (addressed below)).

                  Under the Plan, Allowed Claims for professional fees and
expenses will be paid in accordance with the Bankruptcy Court order allowing
such fees and expenses. The Debtors estimate that Allowed Claims for
professional fees and expenses that have not been paid pursuant to prior order
of the Bankruptcy Court and were not paid by Schlumberger pursuant to the Sale
will be less than $1,000,000.

         B.       Priority Tax Claims

                  Under the Plan, the Debtors will make a Distribution in an
amount equal to the amount of the Allowed Priority Tax Claim to each holder of
an Allowed Priority Tax Claim, if any. Such payment will be made on the First
Distribution Date or on the fifteenth (15th) day after such later date that such
Claim becomes an Allowed Priority Tax Claim, unless the holder shall have agreed
to different treatment of such Claim. The Debtors estimate that Allowed Priority
Tax Claims will amount to less than $400,000.

         C.       Class 1 - Priority Non-Tax Claims

                  Priority Claims consist of all Claims that are entitled to
priority pursuant to sections 507(a)(2)-(7) and (9) of the Bankruptcy Code,
including: (1) unsecured claims for accrued employee compensation earned within
ninety (90) days prior to the Petition Date, to the extent of $4,300 per
employee; (2) unsecured claims for contributions to employee benefit plans
arising from services rendered within one hundred eighty (180) days prior to the
Petition Date, but only to the extent of (a) the number of employees covered by
such plans multiplied by $4,300, less (b) the aggregate amount paid to such
employees from the estate for wages, salaries or compensation; and (3) unsecured
claims of individuals, to the extent of $1,950 for each such individual, arising
from the deposit, before the Petition Date, of money in connection with the
purchase, lease, or rental of property, or the purchase of services, or the
personal, family, or household use of such individuals, that were not delivered
or provided. The Debtors estimate that Allowed Priority Claims and allowed
Priority Non-Tax Claims, combined, will amount to less than $1,000,000.

                  Under the Plan, the legal, equitable, and contractual rights
of Allowed Priority Claims will be left unaltered and the Debtors will make a
Distribution in an amount equal to the amount of the Allowed Priority Claim to
each holder of an Allowed Priority Claim, if any. Such Distributions will be
made on the First Distribution Date or on the fifteenth (15th) day after such
later date that such Claim becomes an Allowed Claim, as applicable, whichever is
later, unless such holder shall have agreed to different treatment of such
Claim.

         D.       Class 2 - Secured Claims

                  Class 2 consists of all Secured Claims. The Debtors expect
there will be no Secured Claims.


                                      16
<PAGE>

                  Under the Plan, the legal, equitable, and contractual rights
of Allowed Secured Claims will be left unaltered and the Debtors will make a
Distribution in an amount equal to the amount of the Allowed Secured Claim to
each holder of an Allowed Secured Claim, if any. Such Distributions will be made
on the First Distribution Date or on the fifteenth (15th) day after such later
date that such Claim becomes an Allowed Claim, as applicable, whichever is
later, unless such holder shall have agreed to different treatment of such
Claim.

         E.       Class 3 - General Unsecured Claims

                  Class 3 consists of all Allowed Unsecured Claims. Each Allowed
Unsecured Claim in Class 3 shall be paid Cash equal to its Pro Rata share of the
Cash available to the Estates after satisfaction of Allowed Administrative
Claims, Allowed Priority Tax Claims and Allowed Priority Claims. Such Cash shall
be paid in a series of Distributions, beginning on the First Distribution Date.
The Debtors estimate that the amount of Class 3 Claims is approximately
$405,000,000; however, this amount is strictly an estimate as the Debtors have
not conducted a detailed analysis of such claims.

                  Under the plan, no Distribution shall be made to the holder of
a Disputed Class 3 Claim unless and until a Final Order providing that such
Claim has become an Allowed Claim has been entered by the Clerk of the
Bankruptcy Court.

         F.       Class 4 - Preferred Interests in the Debtors

                  Class 4 consists of all Interests in the Debtors arising from
the ownership of Preferred Stock. On the Effective Date, all Interests in the
Debtors and all related agreements shall be canceled. Holders of Allowed Class 4
Interests will receive no distribution and retain no rights or property on
account of their Allowed Class 4 Interests.

         G.       Class 5 - Common Interests in the Debtors

                  Class 5 consists of all Interests in the Debtors arising from
the ownership of Common Stock. On the Effective Date, all Interests in the
Debtors and all related agreements shall be canceled. Holders of Allowed Class 5
Interests will receive no distribution and retain no rights or property on
account of their Allowed Class 5 Interests.


V.       IDENTIFICATION OF CLASSES OF CLAIMS AND
         INTERESTS IMPAIRED AND NOT IMPAIRED BY THE PLAN

         A.       Classes Not Impaired by the Plan

                  Class 1 and Class 2 are not Impaired. Under section 1126(f) of
the Bankruptcy Code, holders of Allowed Claims in such classes are conclusively
presumed to have voted to accept the Plan, and therefore, the votes of such
holders will not be solicited.


                                      17
<PAGE>

         B.       Classes Impaired by the Plan

                  Class 3, Class 4 and Class 5 are Impaired by the Plan.  The
holders of Allowed Claims in Class 3 are entitled to vote to accept or reject
the Plan.

         C.       Classes Presumed to Reject the Plan

                  Class 4 and Class 5 will not receive any Distributions under
the Plan. Under Bankruptcy Code section 1126(g), holders of these Interests are
conclusively deemed to have rejected the Plan and, therefore, the votes of such
holders will not be solicited.


VI.      IMPLEMENTATION OF THE PLAN

                  Substantially all of the funds to effect the Distributions
provided under the Plan will be generated from proceeds from the Sale or other
dispositions of the Debtors' assets. As set forth in Section IV above, (i) the
Debtors will make Distributions to holders of Allowed Administrative Claims,
Allowed Priority Tax Claims, Class 1 Claims, and Class 2 Claims on the First
Distribution Date or on the fifteenth (15th) day after such later date that such
Claim becomes an Allowed Claim, as applicable, whichever is later, unless such
holder shall have agreed to different treatment of such Claim, (ii) in the case
of Class 3, Cash remaining after the aforementioned Distributions will be paid
in a series of distributions, beginning on the First Distribution Date, and
(iii) the Debtors will not make any Distributions to holders of Interests in
Class 4 and Class 5. All Distributions to holders of Senior Discount Notes shall
be made to the indenture trustee for the benefit of such holders.


VII.     THE PLAN CONFIRMATION PROCESS

         A.       Acceptance and Confirmation

                  At the Confirmation Hearing, the Bankruptcy Court will confirm
the Plan only if all the requirements of section 1129 of the Bankruptcy Code are
met. Section 1129 requires that the Plan is (i) accepted by the impaired class
of claims or, if rejected by the impaired class, that the Plan "does not
discriminate unfairly" and is "fair and equitable" as to the Class, (ii)
feasible, and (iii) in the best interests of creditors whose claims are impaired
under the Plan.

         B.       Acceptance of the Plan

                  In order for a plan to be accepted by any class, it must be
accepted by creditors who hold at least two-thirds in dollar amount of the
claims in such impaired class as to which votes are cast, and who comprise more
than one-half of the voting creditors holding claims in such class. A class is
impaired if the legal, equitable, or contractual rights attached to the claims
in that class are modified, other than by curing defaults and reinstating
maturity or payment in full in cash. Creditors whose claims are not impaired by
the Plan may not vote and are conclusively presumed, pursuant to the Bankruptcy
Code, to have accepted the Plan.


                                      18
<PAGE>

                  If any impaired class does not accept a plan, a debtor may
nevertheless seek confirmation of the plan. As set forth by section 1129(b) of
the Bankruptcy Code, to obtain such confirmation and "cram-down" on the
dissenting class or classes, a debtor must demonstrate to the Bankruptcy Court
that the Plan "does not discriminate unfairly" and is "fair and equitable" with
respect to each dissenting class. A plan does not discriminate unfairly if,
among other things, the dissenting class is treated substantially equally with
respect to other classes of equal rank. A debtor will satisfy the "fair and
equitable" test if a debtor can demonstrate to the Bankruptcy Court that either:
(a) each holder of a claim or interest in the dissenting classes receives or
retains, under the plan, property of a value equal to the allowed amount of its
claim or interest; or (b) the holders of Interests that are junior to the
interests of the holders of such dissenting class will not receive or retain any
property under the plan.

                  As holders of impaired Claims who will not receive any
Distributions under the Debtors' Plan, Class 4 and Class 5 are deemed to reject
the Plan and, therefore, are the dissenting classes. For the purposes of
"cramming down" on holders of Interests in Class 4 and Class 5, the Debtors must
show, pursuant to section 1129(b)(2)(C) of the Bankruptcy Code, that the Plan is
"fair and equitable" as to these dissenting classes of Interests. The Debtors
believe that they satisfy this "fair and equitable" test as to Class 4 and Class
5, as no class junior to Class 3 receives a Distribution. Accordingly, the
requirements of section 1129(b) of the Bankruptcy Code are satisfied and the
Debtors can "cram-down" on these dissenting classes.

         C.       Feasibility

                  As a condition to confirmation of a plan, section 1129(a) of
the Bankruptcy Code requires that the confirmation of the Plan is not likely to
be followed by the liquidation of the Debtors (unless, like here, such
liquidation is proposed in the Plan) or the need for further financial
reorganization. Since liquidation is proposed in the Plan, the Debtors believe
that the Plan meets the feasibility requirement and that it will be able to make
all payments required by the Plan without the necessity for further financial
reorganization.

         D.       Best Interests Test

                  Confirmation of a plan also requires that each claimant either
(a) accept the plan or (b) receive or retain under the plan property of a value,
as of the effective date of the plan, that is not less than the value such
claimant would receive or retain if the debtor was liquidated under chapter 7 of
the Bankruptcy Code.

                  To determine what creditors and holders of interests would
receive if a debtor was liquidated, the Bankruptcy Court must determine the
dollar amount that would be generated from the liquidation of the debtor's
assets and properties in the context of a chapter 7 liquidation case. Such cash
amount would be reduced by the cost and expenses of liquidation and by
additional administrative priority claims that would result from, in all
likelihood, a chapter 7 liquidation.

                  The cost of liquidation under chapter 7 would include the fees
payable to a trustee, as well as those that might be payable to additional
attorneys and other professionals that such


                                      19
<PAGE>

trustee may engage, plus any unpaid expenses incurred by the Debtors during
their Cases, such as compensation for attorneys, financial advisors, and
accountants.

                  The Debtors believe that all Unsecured Claims will receive
greater value under the Plan than in a chapter 7 liquidation and that the Plan
satisfies the "best interests of the creditors" test. In addition, Interest
holders would not be entitled to receive any distributions on account of their
Interests in either a chapter 7 or chapter 11 case since Unsecured Creditors
would not receive payment in full in either scenario.


VIII.    GENERAL FEDERAL INCOME TAX CONSIDERATIONS

                  The confirmation and execution of the Plan may have tax
consequences to holders of Claims and Interests. The Debtors do not offer an
opinion as to any federal, state, local, or other tax consequences to holders of
Claims and Interests as a result of the confirmation of the Plan. All holders of
Claims and Interests are urged to consult their own tax advisors with respect to
the federal, state, local, and foreign tax consequences of the Plan. THIS
DISCLOSURE STATEMENT IS NOT INTENDED, AND SHOULD NOT BE CONSTRUED, AS LEGAL OR
TAX ADVICE TO ANY CREDITOR.


IX.      ALTERNATIVES TO CONFIRMATION AND CONSUMMATION OF THE PLAN

                  If the Plan is not confirmed and consummated, the alternatives
include (a) liquidation of the Debtors under chapter 7 of the Bankruptcy Code,
or (b) dismissal of the Cases.

         A.       Liquidation Under Chapter 7

                  If no plan can be confirmed, the Cases may be converted to
cases under chapter 7 of the Bankruptcy Code, in which a trustee would be
elected or appointed to liquidate the assets of the Debtors for distribution to
their creditors in accordance with the priorities established by the Bankruptcy
Code. The Debtors believe that conversion of the Cases to cases under chapter 7
of the Bankruptcy Code would result in diminished distributions to all creditors
due to increased costs of administration and the resultant delay in distribution
on account of any such conversion.

                  Thus, the Debtors believe that holders of Unsecured Claims
would receive a lower distribution on account of the additional expenses
incurred from conversion of the Cases to chapter 7 cases.

         B.       Alternative Plan of Reorganization

                  If the Plan is not confirmed, the Debtors, the Creditors'
Committee, or any of the parties in interest could attempt to formulate a
different Plan. The Debtors believe that the Plan described herein will provide
the greatest and most expeditious return to creditors.


                                      20
<PAGE>

X.       FINANCIAL INFORMATION

         A.       Postpetition Financial Information

                  The Debtors have filed Statements of Financial Affairs and
Schedules of Assets and Liabilities with the Bankruptcy Court as required by the
Bankruptcy Code. As debtors in possession, the Debtors have filed monthly
operating reports with the United States Trustee. This financial information may
be examined in the Bankruptcy Court Clerk's Office.


XI.      VOTING PROCEDURES AND REQUIREMENTS

         A.       Ballots

                  1. Any Holder of a Class 3 Claim whose claim arises for
reasons other than the holding of Senior Discount Notes can vote by completing
and signing the ballot attached hereto as Exhibit C (the "Non-Noteholder
Ballot") and returning it directly to the Ballot Agent (using the enclosed
pre-addressed postage-paid envelope) so as to be received by the Ballot Agent
before the Voting Deadline. If no envelope was enclosed, contact the Ballot
Agent for instructions.

                  2. Any Holder of a Class 3 Claim who is a beneficial owner, as
of the Voting Record Date, of the Senior Discount Notes in his, her or its own
name can vote by completing and signing the ballot attached hereto as Exhibit D
(the "Beneficial Owner Ballot" or "Ballot") and returning it directly to the
Ballot Agent (using the enclosed pre-addressed postage-paid envelope) so as to
be received by the Ballot Agent before the Voting Deadline. If no envelope was
enclosed, contact the Ballot Agent for instructions.

                  3. Any beneficial owner holding, as of the Voting Record Date,
the Senior Discount Notes in "street name" through a transfer agent, broker,
financial institution, registrar, servicing agent, or other intermediary holding
Claims for or acting on behalf of record holders of Claims (each a "Nominee")
can vote by completing and signing the Ballot (unless the Ballot has already
been signed, or "prevalidated," by the Nominee), and returning it to the Nominee
in sufficient time for the Nominee to then forward the vote so as to be received
by the Ballot Agent before the Voting Deadline. Any Ballot submitted to a
Nominee will not be counted until such Nominee properly completes and timely
delivers a corresponding ballot attached hereto as Exhibit E ("Nominee Master
Ballot") to the Ballot Agent. If your Ballot has already been signed (or
"prevalidated" by your Nominee, you must complete the Ballot and return it
directly to the Ballot Agent so that it is received before the Voting Deadline.

                  4. A Nominee which, on the Voting Record Date, is the
registered holder of Senior Discount Notes for a beneficial owner can obtain
votes of the beneficial owners of such securities in one of the following two
ways:


                                      21
<PAGE>

                           The Nominee may "prevalidate" a Ballot by (i) signing
                  the Ballot; (ii) indicating on the Ballot the name of the
                  registered holder, the amount of securities held by the
                  Nominee for the beneficial owner, and the account numbers of
                  the accounts in which such securities are held by the Nominee;
                  and (iii) forwarding such Ballot, together with the Disclosure
                  Statement, return envelope and other materials requested to be
                  forwarded, to the beneficial owner for voting. The beneficial
                  owner must then complete the information requested by the
                  Ballot; review the certifications contained in the Ballot; and
                  return the Ballot directly to the Ballot Agent in the
                  pre-addressed, postage-paid envelope so that it is received by
                  the Ballot Agent before the Voting Deadline. A list of the
                  beneficial owners to whom "prevalidated" Ballots were
                  delivered should be maintained by Nominees for inspection for
                  at least one year from the Voting Deadline.

                                       OR

                           If the Nominee elects not to prevalidate Ballots, the
                  Nominee may obtain the votes of beneficial owners by
                  forwarding to the beneficial owners the unsigned Ballots,
                  together with the Disclosure Statement, a return envelope
                  provided by, and addressed to, the Nominee, and other
                  materials requested to be forwarded. Each such beneficial
                  owner must then indicate his, her or its vote on the Ballot,
                  complete the information requested in the Ballot, review the
                  certifications contained in the Ballot, execute the Ballot and
                  return the Ballot to the Nominee. After collecting the
                  Ballots, the Nominee should, in turn, complete a Nominee
                  Master Ballot compiling the votes and other information from
                  the Beneficial Owner Ballots, execute the Nominee Master
                  Ballot and deliver the Nominee Master Ballot to the Ballot
                  Agent so that it is received by the Ballot Agent before the
                  Voting Deadline. Please Note: the Nominee should advise the
                  beneficial owner to return his, her or its Ballot to the
                  Nominee by a date calculated by the Nominee to allow it to
                  prepare and return the Master Ballot to the Ballot Agent so
                  that it is received by the Ballot Agent before the Voting
                  Deadline.


         B.       Nominees

                  In accordance with Bankruptcy Rule 3017(d), the Debtors shall
send ballots to each Nominee. Each Nominee shall be entitled to receive, upon
request of the Debtors reasonably sufficient copies of ballots and other voting
materials to distribute to the beneficial owners of the Claims for which it is a
Nominee. Nominees shall follow the voting directions as set forth above.


                                      22
<PAGE>

                  The Debtors shall be responsible for and pay each Nominee's
reasonable costs and expenses associated with the distribution of copies of
ballots and other applicable voting materials to the beneficial owners of such
Claims and tabulation of the ballots.


XII.     CONCLUSION

                  The Debtors urge holders of impaired Claims to vote to accept
the Plan.
