                                OPTION AGREEMENT

                                       AND

                      AGREEMENT AND PLAN OF REORGANIZATION

         THIS OPTION AGREEMENT AND AGREEMENT AND PLAN OF REORGANIZATION (this
"Agreement") is made as of February 7, 1996 among METRICOM, INC., a Delaware
corporation ("Metricom"), OVERALL WIRELESS COMMUNICATIONS CORPORATION, an
   
Oklahoma corporation ("Overall Wireless"), and Jean Warren, the sole stockholder
    
of Overall Wireless ("Stockholder").

                                    RECITALS

         A.       Overall Wireless is the holder of a Nationwide Commercial
license issued by the Federal Communications Commission (the "FCC"), assigned
the call sign WPCU 518, covering five 5-KHz channel pairs in the 220-222 MHz
frequency band for a total of 50 KHz of spectrum (the "FCC License").

         B.       Metricom desires to purchase an option to acquire Overall
Wireless, and Overall Wireless and Stockholder wish to sell such option to
Metricom, on the terms and subject to the conditions contained in this
Agreement.

         C.       The parties intend to effect such acquisition upon exercise of
such option through a merger (the "Merger") of Overall Wireless into a
wholly-owned subsidiary of Metricom ("Sub") in accordance with this Agreement,
the rules and regulations of the FCC and the laws of the State of Delaware and
the State of Oklahoma, or such state law as will be applicable to Overall
Wireless or its successor upon the date of the Merger (collectively, the
"Applicable Laws"). Upon consummation of the Merger, Overall Wireless will merge
into Sub, and Sub will remain a wholly-owned subsidiary of Metricom.

         D.       It is intended that the Merger qualify as a tax-free
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code").

                                    AGREEMENT

                  The parties to this Agreement agree as follows:

1.       PURCHASE AND SALE OF OPTION.

         1.1      OPTION.

         (a)      Metricom is hereby granted the option (the "Option") to
acquire 100% ownership of all outstanding equity securities of Overall Wireless
through the Merger, exercisable at any time after Forty Percent Completion (as
defined in Section 5.1(b)(2)) is achieved but not later than January 1, 1997 (or
such later date as may be determined pursuant to Section 1.4).

         (b)      Metricom will exercise the Option by giving Overall Wireless
and Stockholder written notice of its intent to exercise (the "Notice"). Within
ten days after delivery of the Notice, Overall Wireless will deliver a revised
Disclosure Schedule (as defined in Section 3) to Metricom. In the event such
Disclosure Schedule contains exceptions to the representations and warranties
contained in Section 3 of this Agreement that, in Metricom's reasonable
judgment, represent material adverse differences from the state of Overall
Wireless' business, financial condition, assets, liabilities, operations or
prospects (or in any aspect or portion thereof) from Metricom's knowledge
thereof upon Metricom's exercise of the Option, Metricom may rescind the Notice
by delivering written notice to Overall Wireless and the Stockholder within ten
days after delivery of the Disclosure Schedule. If the Option is exercised and
such exercise is not rescinded, the parties will consummate the Merger within
[*] after all of the conditions contained in Sections 6 and 7, including,
without limitation, FCC approval of the Merger, have been fulfilled or waived,
provided that this Agreement has not been terminated in accordance with the
provisions of Section 8 hereof.

         1.2      OPTION PURCHASE PRICE. As consideration for the Option,
Metricom will deliver $700,000 in cash to Stockholder upon the execution of this
Agreement.

         1.3      FURTHER ASSURANCES. Except as otherwise provided for herein,
(a) Stockholder will vote, if Metricom exercises and does not rescind its
exercise of the Option, all of her voting securities of Overall Wireless in
favor of the Merger, and against any proposal made in opposition to the
Agreement or the transactions contemplated thereby; (b) Stockholder will not
transfer, sell, exchange, pledge (other than pursuant to the Stock Pledge
Agreement (as defined in Section 5.1(b)(3)), offer or otherwise dispose of or
encumber any of her Overall Wireless securities, or make any offer or agreement
relating thereto, except through the Merger; and (c) Overall Wireless will not
permit any transfer or issuance of Overall Wireless securities. Promptly after
the achievement of Forty Percent Completion and the adoption of the Proposed FCC
Rule Changes (as defined below), the parties will complete and file with the FCC
an application for assignment or transfer of control of the FCC License by or
from Overall Wireless to Metricom.

         1.4      OPTION EXTENSION/TERMINATION.

                  (a)      If on January 1, 1997 [*], Metricom may extend the
Option exercise deadline to July 1, 1997 by delivering a written notice of
extension and $500,000 in cash to Stockholder in exchange for such extension.
Notwithstanding the foregoing, if Overall Wireless or Stockholder has committed
any material Breach, the Option exercise deadline will automatically extend to
the later of (1) July 1, 1997; and (2) such time as the Breach has been cured,
without any payment or further action by Metricom. For the purposes of this
Agreement, "Breach" means any inaccuracy in or breach of, or any failure to
comply with or perform, a representation, warrant, covenant, obligation or other
provision of this Agreement.

                  (b)      If on January 1, 1997 [*], then Metricom may either:

                           (1)      extend the Option term as set forth in
Section 1.4(a); or

                           (2)      terminate the Option by delivering notice
thereof to Overall Wireless and Stockholder, in which case Stockholder will
immediately refund $350,000 of the Option purchase price to Metricom.

                  (c)      If the Option expires, other than through Metricom's
exercise of its rights under Section 1.4(b)(2), this Agreement will terminate,
subject to the provisions of Section 8.3.

2.       MERGER.

         2.1      MERGER OF OVERALL WIRELESS INTO SUB. On the terms and subject
to the conditions contained in this Agreement, at the Effective Time (as defined
in Section 2.3), Overall Wireless will be merged into Sub and the separate
existence of Overall Wireless will cease. Sub will be the surviving corporation
in the Merger (the "Surviving Corporation").

         2.2      EFFECT OF THE MERGER. The Merger will have the effects set
forth in this Agreement and in the Applicable Laws.

         2.3      CLOSING; EFFECTIVE TIME. The consummation of the Merger (the
"Closing") will take place at the offices of Cooley Godward Castro Huddleson &
Tatum, One Maritime Plaza, 20th Floor, San Francisco, California on the fifth
calendar day following the date as of which each of the conditions set forth in
Sections 6 and 7 has been fulfilled or waived or on such other date as may be
jointly designated by Metricom and Overall Wireless (the "Closing Date"). As
soon as practicable after the Closing, a properly executed certificate of merger
in substantially the form attached hereto as EXHIBIT A-1 and conforming to the
requirements of the Applicable Laws (the "Certificate of Merger") will be filed
in accordance with the Applicable Laws, at which time the Merger will become
effective (the "Effective Time").

         2.4      CERTIFICATE OF INCORPORATION AND BYLAWS; DIRECTORS AND
OFFICERS. Unless otherwise determined by Metricom prior to the Effective Time,
(a) the Certificate of Incorporation of the Surviving Corporation will be
amended and restated as of the Effective Time to conform to the Certificate of
Incorporation of Sub; (b) the Bylaws of the Surviving Corporation will be the
Bylaws of Sub as in effect immediately prior to the Effective Time; (c) the
directors of the Surviving Corporation immediately after the Effective Time will
be Robert P. Dilworth, William D. Swain and Gary M. Green; and (d) the officers
of the Surviving Corporation will be Robert P. Dilworth (President and Chief
Executive Officer), William D. Swain (Chief Financial Officer and Secretary) and
Gary M. Green (Executive Vice President and Chief Operating Officer).

         2.5      CONVERSION OF SHARES.

                  (a)      At the Effective Time, by virtue of the Merger and 
without any action on the part of any party to this Agreement, each
outstanding share of Common Stock, $1.00 par value, of Overall Wireless
("Overall Wireless Common Stock") outstanding immediately prior to the
Effective Time will be converted into the right to receive, subject to any
decreases called for by Section 2.5(b), (1) cash in an amount equal to [*]
divided by the number of shares of Overall Wireless Common Stock outstanding
immediately prior to the Effective Time; and (2) that number of shares of
Common Stock, $0.001 par value, of Metricom ("Metricom Common Stock") equal to
the Conversion Number (as defined below). The "Conversion Number" will be
determined by dividing [*] by the product of Metricom Average Price (as defined
below) and the number of shares of Overall Wireless Common Stock outstanding
immediately prior to the Effective Time, and then rounding the resulting
quotient to three decimal places. The "Metricom Average Price" means [*].

                  (b)      To the extent liabilities of Overall Wireless at the
Effective Time exceed those incurred in constructing, maintaining and
operating the system of base stations and associated mobile stations
contemplated by Section 5.1 to the extent required to keep the FCC License
valid and in good standing, then the cash amount set forth in clause (1) of
Section 2.5(a) will be reduced by the amount of such liabilities. If the
aggregate amount of such liabilities exceeds such cash amount, the [*] amount
set forth in clause (2) of Section 2.5(a) will be reduced by the remaining
amount of such liabilities.

                  (c)      The fraction of a share of Metricom Common Stock into
which each outstanding share of Company Common Stock is to be converted pursuant
to clause (2) of Section 2.5(a) (as such fraction may be adjusted in accordance
with this Section 2.5(c)) is referred to as the "Exchange Ratio." If at any time
prior to the Closing Date, the outstanding shares of Metricom Common Stock are
changed into a different number or class of shares by reason of any stock
dividend, subdivision, reclassification, recapitalization, split-up, combination
or similar transaction, (1) the dollar amounts in the last clause of Section 
2.5(a) will be

appropriately adjusted, and (2) to the extent any such change occurs during the
15 consecutive days ending with the day immediately preceding the Closing Date,
the Exchange Ratio will be appropriately adjusted.

         2.6      CLOSING OF OVERALL WIRELESS' TRANSFER BOOKS. At the Effective
Time, Stockholder and any other holders of certificates representing shares of
Overall Wireless Common Stock will cease to have any rights as stockholders of
Overall Wireless, and the stock transfer books of Overall Wireless will be
closed with respect to all shares of Overall Wireless Common Stock outstanding
immediately prior to the Effective Time. No further transfer of any such shares
of Overall Wireless Common Stock will thereafter be made on such stock transfer
books. If, after the Effective Time, a valid certificate previously representing
any of such shares of Overall Wireless Common Stock (an "Overall Wireless Common
Stock Certificate") is presented to Metricom, such Overall Wireless Common Stock
Certificate will be canceled and exchanged as provided in Section 2.7.

         2.7      EXCHANGE OF CERTIFICATES.

                  (a)      As soon as practicable after the Effective Time,
Metricom will deliver to the holders of Overall Wireless Common Stock
Certificates (1) a letter of transmittal in customary form and containing such
provisions as Metricom may reasonably specify and (2) instructions for use in
effecting the surrender of Overall Wireless Common Stock Certificates in
exchange for certificates representing Metricom Common Stock. Upon surrender of
a Overall Wireless Common Stock Certificate to Metricom for exchange, together
with a duly executed letter of transmittal and such other documents as may be
reasonably required by Metricom, the holder of such Overall Wireless Common
Stock Certificate will be entitled to receive in exchange therefor cash and a
certificate representing the number of whole shares of Metricom Common Stock
that such holder has the right to receive pursuant to the provisions of this
Section 2, and the Overall Wireless Common Stock Certificate so surrendered will
be canceled. Until surrendered as contemplated by this Section 2.7, each Overall
Wireless Common Stock Certificate will be deemed, from and after the Effective
Time, to represent only the right to receive upon such surrender cash and a
certificate representing shares of Metricom Common Stock (and cash in lieu of
any fractional share of Metricom Common Stock) as contemplated by this Section 
2.

                  (b)      No dividends or other distributions declared or made
with respect to Metricom Common Stock with a record date after the Effective
Time will be paid to the holder of any unsurrendered Overall Wireless Common
Stock Certificate with respect to the shares of Metricom Common Stock
represented thereby, and no cash payment in lieu of any fractional share will be
paid to any such holder, until such holder surrenders such Overall Wireless
Common Stock Certificate in accordance with this Section 2.7 (at which time such
holder will

be entitled to receive all such dividends and distributions and such cash
payment) without interest.

                  (c)      No certificates or scrip for fractional shares of
Metricom Common Stock will be issued, but in lieu thereof each holder of shares
of Overall Wireless Common Stock who would otherwise be entitled to receive a
certificate or scrip for a fraction of a share of Metricom Common Stock will
receive from Metricom a cash amount equal to the product of the Metricom Average
Price and the fraction of a share of Metricom Common Stock to which such holder
would otherwise be entitled.

            
         2.8 ADDITIONAL PAYMENT.

                  (a)     If the FCC License or the stock or
other equity interest of its holder while under Metricom's control is sold for
consideration attributable to the FCC License greater than the Acquisition
Consideration (as defined below) in total consideration (valued as set forth in
Section 2.8(b), "Appraised Value") at any time prior to December 31, 1999,
Metricom will, upon the determination of the Appraised Value, pay to each person
or entity who held Overall Wireless Common Stock immediately prior to the
Effective Time cash (the "Additional Payment") in an amount equal to the product
of:

                        [*]
                  As used in this Section 2.8, "Acquisition Consideration"
means the sum of (A) [*], (B) any amount paid to extend the term of the Option
pursuant to Section 1.4, (C) the difference between the amount paid to the
holders of Overall Wireless Common Stock pursuant to Clause (1) of Section
2.5(a) and [*], and (D) interest at the annual rate of [*] on the sum of (A),
(B) and (C) above from the Closing Date until the date of sale.

                  (b)      Metricom will give Stockholder notice of the
disposition of the FCC License (the "Appraisal Notice") within 20 days after
the closing of the transaction. The Appraisal Notice will describe the
transaction in reasonable detail and set forth Metricom's estimate of the
Appraised Value. The Appraised Value may be established by written agreement
signed by Metricom and persons who held greater than 50% of the Overall
Wireless Common Stock outstanding immediately prior to the Effective Time. If
such agreement is not reached, then three independent third-party appraisers
will be selected for the purpose of determining the Appraised Value. The first
appraiser will be appointed by Metricom within 30 days after delivery of the
Appraisal Notice. The second appraiser will be appointed by persons who held
greater than 50% of the Overall Wireless Common Stock outstanding immediately
prior to the Effective Time within 30 days after delivery of the Appraisal
Notice. The third appraiser will be appointed by the first two appraisers
within ten days after the first two appraisers have been appointed. If either
side fails to appoint an independent third-party appraiser within the required
period, then the Appraised Value will be determined solely by the independent
third-party appraiser appointed by the other side. Within 30 days of their
selection, the appraisers will each determine the fair market value of the
consideration received by Metricom for the FCC License only. The Appraised
Value will be the average of the two appraisals closest in dollar amount. All
fees and expenses of the appraisers will be shared equally by Metricom and the
former holders of Overall Wireless Common Stock entitled to a payment under
Section 2.8(a).

                  (c)      If the tax basis of the FCC License, the stock of
Sub or any other asset of Metricom or its subsidiaries increased as a result of
the Additional Payment, the Applicable Percentage will be [*]. If not, the
Applicable Percentage will be [*].

                  (d)      This Section 2.8 will be of no force and effect if
the FCC License is sold as part of a "business" (whether or not in subsidiary
form) meeting the conditions for a "significant subsidiary" of Metricom within
the meaning of Rule 1-02 of Regulation S-X under the Securities Act.

                  2.9      FEDERAL INCOME TAX CONSEQUENCES. For federal income
tax purposes, the Merger is intended to constitute a tax-free reorganization
within the meaning of Section 368(a) of the Code. Neither Overall Wireless nor
Metricom will take a position inconsistent with this Section 2.9 on any tax
return.

                  2.10     ACCOUNTING CONSEQUENCES. For accounting purposes, the
Merger is intended to be treated as a "purchase."

                  2.11     FURTHER ACTION. If at any time after the Effective
Time any further action is determined by Metricom to be necessary to carry out
the purposes of this Agreement or to vest the Surviving Corporation with the
full right, title and possession of and to all assets, property, rights,
privileges, immunities, powers and franchises of Sub and Overall Wireless, the
officers and directors of the Surviving Corporation will be fully authorized (in
the name of Sub, in the name of Overall Wireless and otherwise) to take such
action.

                  2.12     STRUCTURE OF MERGER. In the event Overall Wireless
ceases to be a validly existing S Corporation (as defined in Section 3.1) prior
to the Effective Time, Metricom may, at its option, restructure the acquisition
into a merger of Sub into Overall Wireless. In such event, at the Effective
Time, (a) Sub will be merged into Overall Wireless and the separate existence of
Sub will cease; (b) Overall Wireless will be the Surviving Corporation; and (c)
the Certificate of Merger will be in substantially the form attached hereto as
EXHIBIT A-2. If the acquisition is restructured as set forth in this Section 
2.12, the parties understand that the Merger will not be a tax-free
reorganization within the meaning of Section 368(a) of the Code.

3.       REPRESENTATIONS AND WARRANTIES OF OVERALL WIRELESS AND STOCKHOLDER.

         Except as set forth on the Schedule of Exceptions attached hereto as
EXHIBIT B, Overall Wireless and Stockholder, jointly and severally, hereby
represent and warrant to Metricom as follows:

         3.1      ORGANIZATION, GOOD STANDING AND QUALIFICATION. Overall
Wireless is a corporation duly organized, validly existing and in good standing
under the laws of its state of incorporation. Overall Wireless has all requisite
corporate power and authority to own and operate its properties and assets, to
execute and deliver this Agreement and the Certificate of Merger and to carry
out the provisions of this Agreement and the Certificate of Merger and to carry
on its business as presently conducted and as presently proposed to be
conducted. Overall Wireless is duly qualified and is authorized to do business
and is in good standing as a foreign corporation in all jurisdictions in which
the nature of its activities and of its properties (both owned and leased) makes
such qualification necessary, except for those jurisdictions in which failure to
do so would not have a Material Adverse Effect (as defined below) on Overall
Wireless. Overall Wireless owns no equity securities of any other corporation,
limited partnership or similar entity. Overall Wireless is not a participant in
any joint venture, partnership or similar arrangement. Overall Wireless is and
has been since inception a validly existing "subchapter S" corporation for
federal income tax purposes and under analogous provisions, to the extent they
exist, of the laws of each state in which Overall Wireless has qualified to do
business or is required to qualify to do business (an "S Corporation"). As used
in this Agreement, the term "Material Adverse Effect" means a material adverse
effect on the affected party's business, financial condition, assets,
liabilities or operations.

         3.2      CAPITALIZATION; VOTING RIGHTS. The authorized capital stock of
Overall Wireless consists of 50,000 shares of Common Stock, 100 shares of which
are issued and outstanding. All issued and outstanding shares of Overall
Wireless' Common Stock (a) have been duly authorized and validly issued to, and
are currently owned beneficially and of record, subject to no mortgage, pledge,
lien, encumbrance or charge, by Stockholder; (b) are fully paid and
nonassessable; and (c) were issued in compliance with all applicable state and
federal laws concerning the issuance of securities. Except as set forth in this
Agreement, there are no outstanding options, warrants, rights (including
conversion or preemptive rights and rights of first refusal), proxy or
stockholder agreements, or agreements of any kind for the purchase or
acquisition from Overall Wireless or Stockholder of any of Overall Wireless'
securities.

         3.3      AUTHORIZATION; BINDING OBLIGATIONS. All corporate action on
the part of Overall Wireless, its officers, directors and stockholders necessary
for the authorization of this Agreement and the Certificate of Merger, the
performance of all obligations of Overall Wireless thereunder and the
authorization of the Merger has been taken. This Agreement is a valid and
binding obligation of Overall Wireless and Stockholder, enforceable in
accordance with its terms, except (a) as limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other laws of general application
affecting enforcement of creditors' rights; (b) as limited by general principles
of equity that restrict the availability of equitable remedies; and (c) as the
indemnification provisions of Sections 5.9 and 9 of this Agreement may be
limited by applicable law.

         3.4      FCC COMPLIANCE; LICENSE OWNERSHIP. The FCC License was
originally issued to Stockholder on July 29, 1993, and was validly assigned to
Overall Wireless on July 13, 1994. The Application (as defined in Section 
5.1(a)) and all amendments thereto, and the application to assign the FCC
License to Overall Wireless and all amendments thereto, complied in all respects
with all applicable FCC rules and regulations. All applicable periods relating
to FCC reconsideration of the issuance of the FCC License and assignment of the
FCC License to Overall Wireless have expired. Overall Wireless currently holds
the FCC License, subject to no mortgage, pledge, lien, encumbrance or charge.
The FCC License has not been impaired by any act or omission of Stockholder or
Overall Wireless or any of their employees, representatives or agents. The FCC
has not imposed any conditions on Stockholder or Overall Wireless on the use of
the FCC License that is not contained on the face thereof or in the FCC rules
and regulations. There has been no actual or, to the best of Overall Wireless'
and Stockholder's knowledge, threatened action by or before the FCC to revoke,
cancel, rescind or modify the FCC License in any manner. Neither Stockholder nor
Overall Wireless has received any notice of liability, forfeiture or complaint
against the FCC License with respect to any actions taken by either of them
under authority of, or in connection with, the FCC License. Stockholder and
Overall Wireless have complied and are in compliance with all FCC rules and
regulations governing the FCC License and ownership and operation of the
facilities described in the FCC License. Stockholder and Overall Wireless have
filed with the FCC all statements, reports and information required by
applicable FCC rules and regulations. Stockholder and Overall Wireless know of
no facts that could cause the FCC to deny its consent to the assignment of the
FCC License to Metricom as contemplated in this Agreement.

         3.5      FINANCIAL STATEMENTS. Overall Wireless has delivered to
Metricom its unaudited balance sheet as at December 31, 1995 (the "Statement
Date") and unaudited statement of income for the year then ended (collectively,
the "Financial Statements"). The Financial Statements are complete and correct
in all material respects, have been prepared in accordance with accounting
principles applied on a consistent basis throughout the periods indicated and
present fairly the financial condition and position and results of operations of
Overall Wireless as of the Statement Date and for the year then ended.

         3.6      LIABILITIES. Overall Wireless has no material liabilities and,
to the best of Overall Wireless' and Stockholder's knowledge, no material
contingent liabilities, not disclosed in the Financial Statements, except
liabilities incurred in the ordinary course of business subsequent to the
Statement Date that have not been, either in any case or in the aggregate,
material.

         3.7      AGREEMENTS; ACTION. Except for obligations relating to
construction and operation of facilities for the FCC License or otherwise
expressly contemplated by this Agreement:

(including persons or entities Overall Wireless has reason to believe are
affiliated therewith) will be aggregated for the purpose of meeting the
individual minimum dollar amounts of such subsections.
    

         3.8      CHANGES. Since the Statement Date, other than obligations
relating to construction and operation of facilities for the FCC License or

mortgage, pledge, lien, encumbrance or charge upon any of the properties or
assets of Overall Wireless or the suspension, revocation, impairment, forfeiture
or nonrenewal of any permit, license, authorization or approval applicable to

statement on Form S-1 or other appropriate form of registration statement for
the general registration of securities under the Securities Act, including,
without limitation, Form S-3 (or any successor form to Form S-3) for a public
distribution of shares of Metricom Common Stock issued to Stockholder in the

efforts to cause such securities to be registered for the public distribution
thereof [*].

                  (b)      In the event Metricom at any time or from time to
time decides to register any Metricom Common Stock, whether or not for its own

Stockholder written notice thereof (which will include a list of the

under the applicable blue sky or other state securities laws) and (2) include in

compliance), and in any underwriting involved therein, [*] the Metricom Common
Stock specified in a written request delivered to Metricom by Stockholder within
20 days after delivery of such written notice from Metricom

                           (1)      If the registration of which Metricom gives
notice is for a registered public offering involving an underwriting, the
Company will so advise Stockholder as a part of the written notice given

with the other holders distributing their securities through such underwriting)
enter into an underwriting agreement containing terms not inconsistent with this

limitation, the aggregate number of shares of Metricom Common Stock requested to
be registered, the general condition of the market, and the status of the
persons proposing to sell securities pursuant to the registration) require a
limitation of the number of shares to be underwritten, the Underwriter's

                           (3)      Furnish to Stockholder, without charge, such

reasonably requested by Stockholder, provided that Metricom will not be required
in connection therewith or as a condition thereto to qualify to do business or
to file a general consent to service of process in any such states or
jurisdictions;

                           (5)      Notify Stockholder at any time when a

such registration statements, as then in effect, includes an untrue statement of

or necessary to make the statements therein not misleading in the light of the
circumstances then existing and promptly file all amendments necessary to
eliminate such misstatement or omission;

                           (6)      Cause all such shares of Metricom Common
Stock to be listed on each securities exchange or market system on which similar

permitted by law, Stockholder against all Damages (as defined below) caused by
any untrue or alleged untrue statement of material fact contained in any
registration statement, prospectus or preliminary prospectus or any amendment
thereof or supplement thereto or any omission or alleged omission of a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except insofar as the same are caused by or contained in any
information furnished in writing to Metricom by Stockholder for use therein or
by Stockholder's failure to deliver a copy of the registration statement or

untrue statement or omission is contained in any information or affidavit so
furnished in writing solely by Stockholder.

                  (e)      For a period not to exceed [*] days, Metricom will
not be obligated to prepare and file, or be prevented from delaying or
abandoning, or by written notice to the Stockholder, may suspend the use of (and
Stockholder hereby agrees not to use a registration statement during such

the aggregate number of shares of Metricom Common Stock acquired by Stockholder

are included, Stockholder will enter into any standard "lock-up" agreement
required by Underwriter's Representative.

                  (g)      Stockholder, at Stockholder's request and expense,
will have access, at reasonable times and on reasonable advance notice, to

                  (c)      encourage or solicit any employee of Metricom, any of
its subsidiaries or Overall Wireless to leave the employ of such company for any
reason or to devote less than all of any such employee's efforts to the affairs
of such company.

The foregoing covenants will be construed as a series of separate covenants, one
for each nation, each state of the United States, and each county of each such
state. Except for geographic coverage, each such separate covenant will be
identical in terms to the covenants set forth above. If, in any judicial
proceeding, a court refuses to enforce any of such separate covenants (or any
part thereof), then such unenforceable covenant (or such part) will be
eliminated from this Agreement to the extent necessary to permit the remaining
separate covenants (or portions thereof) to be enforced. In the event that any
of the provisions of this Section 5.11 are deemed to exceed the time, geographic
or scope limitations permitted by applicable law, then such provisions will be
reformed to the maximum time, geographic or scope limitations, as the case may
be, permitted by applicable laws.

         5.12     FCC MATTERS. Overall Wireless and Stockholder will act in
compliance with the applicable rules and regulations of the FCC, and will take
whatever actions are necessary in order to ensure that the FCC License remains
in full force and effect and in good standing through the Effective Time. In the
event of any FCC action, or the filing or issuance by the FCC of any order,
notice or complaint against Overall Wireless or Stockholder or any of their
employees or affiliates, or if Stockholder, Overall Wireless or any of Overall
Wireless' officers and directors learn of any threat of such an action, order,
notice or complaint, Overall Wireless will promptly notify Metricom thereof in
writing and take all reasonable measures to contest in good faith or seek
removal, resolution or rescission of such action, order, notice of complaint.

         9.3      THRESHOLD.

                  (a) Subject to Section 9.3(b), neither Stockholder nor
Metricom will be required to make any indemnification payment pursuant to
Section 9.2 for any Breach of any of its representations and warranties until
such time as the total amount of all Damages (including the Damages arising
from such Breach and all other Damages arising from any other Breaches of any
representations or warranties) that have been directly or indirectly suffered
or incurred by any one or more of the Metricom Indemnitees or the Stockholder
Indemnitees, respectively, or to which any one or more of the Metricom
Indemnitees or the Stockholder Indemnitees, respectively, has or have otherwise
become subject, exceeds  [*].

                  (b) The limitation on Stockholders' indemnification
obligations that is set forth in Section 9.3(a) will not apply to (1) any Breach
arising directly or indirectly from any circumstance of which Overall Wireless
or Stockholder had knowledge on or prior to the Closing Date, [*]. The
limitation on Metricom's indemnification obligations that is set forth in
Section 9.3(a) will not apply to (1) any Breach arising directly or indirectly
from any circumstance of which Metricom had knowledge on or prior to the Closing
Date, [*].
    

         9.4      RIGHT TO REQUIRE CURE OF BREACH. Without limiting the
generality of anything contained in Section 9.2, if there is any Breach of any
representation or warranty made by

Overall Wireless or Stockholder, the one hand, or Metricom, on the other hand,
then Stockholder or Metricom, respectively, will be obligated to pay such
amounts to Metricom or Stockholder, respectively, and take such other actions as
Metricom or Stockholder, respectively, may in good faith request for the purpose
of causing such Breach to be corrected, cured and eliminated in all respects (at
no cost to Metricom or Stockholder, respectively).

                  9.5 NO CONTRIBUTION. Stockholder and Metricom each waives, and
acknowledges and agrees that such party will not have and will not exercise or
assert or attempt to exercise or assert, any right of contribution or right of
indemnity or any other right or remedy against Overall Wireless in connection
with any indemnification obligation or any other liability to which such party
may become subject under this Agreement or otherwise in connection with any of
the transactions contemplated hereby.

                  9.6 INTEREST. If a party is required to indemnify any other
person or entity pursuant to this Section 9 with respect to any Damages
representing out-of-pocket payments or losses, such party will also be required
to pay such other person or entity interest on the amount of such Damages (for
the period commencing as of the date on which such other person or entity first
incurred or otherwise became subject to such Damages and ending on the date on
which the applicable indemnification payment is made by Stockholder) at a
floating rate one percentage point above the rate of interest publicly announced
by Bank of America, N.T. & S.A. from time to time as its prime, base or
reference rate, except to the extent the time value of money is already
reflected in the amount of such Damages.

                  9.7 NONEXCLUSIVITY OF INDEMNIFICATION REMEDIES. The
indemnification remedies and other remedies provided in this Section 9 will not
be deemed to be exclusive. Accordingly, the exercise by any person or entity of
any of its rights under this Section 9 will not be deemed to be an election of
remedies and will not be deemed to prejudice, or to constitute or operate as a
waiver of, any other right or remedy that such person or entity may be entitled
to exercise.

                  9.8 EXERCISE OF REMEDIES BY METRICOM INDEMNITEES OTHER THAN
METRICOM. No Metricom Indemnitee (other than Metricom or any successor thereto
or assign thereof) will be permitted to assert any indemnification claim or
exercise any other remedy under this Agreement unless Metricom (or any successor
thereto or assign thereof) has consented to the assertion of such
indemnification claim or the exercise of such other remedy.

10.      MISCELLANEOUS.

         10.1     GOVERNING LAW. This Agreement will be governed in all respects
by the laws of the State of California as such laws are applied to agreements
between California residents entered into and performed entirely in California.

         Borrower covenants and agrees that, until payment in full of all
outstanding Obligations, and for so long as Lender may have any commitment to
make an Advance hereunder, Borrower will do all of the following:

         6.1      GOOD STANDING. Borrower will maintain its corporate existence
and good standing in its jurisdiction of incorporation and maintain
qualification in each jurisdiction in which the failure to so qualify could have
a Material Adverse Effect. Borrower will maintain, to the extent consistent with
prudent management of Borrower's business, in force all licenses, approvals and
agreements, the loss of which could have a Material Adverse Effect.

         6.2      GOVERNMENT COMPLIANCE. Borrower will comply with all statutes,
laws, ordinances and government rules and regulations to which it is subject,
noncompliance with which could have a Material Adverse Effect or a material
adverse effect on the Collateral or the priority of Lender's Lien on the
Collateral.

         6.3      TAXES. Borrower will make due and timely payment or deposit of
all material federal, state, and local taxes, assessments, or contributions
required of it by law, and will execute and deliver to Lender, on demand,
appropriate certificates attesting to the payment or deposit thereof; and
Borrower will make timely payment or deposit of all material tax payments and
withholding taxes required of it by applicable laws, including, but not limited
to, those laws concerning F.I.C.A., F.U.T.A., state disability, and local,
state, and federal income taxes, and will, upon request, furnish Lender with
proof satisfactory to Lender indicating that Borrower has made such payments or
deposits; provided that Borrower need not make any payment if the amount or
validity of such payment is contested in good faith by appropriate proceedings
and is reserved against (to the extent required by GAAP) by Borrower.

         6.4      INSURANCE.

                  (a)      Borrower, at its expense, will maintain liability
insurance and will keep the Collateral insured against loss or damage by fire,
theft, explosion, sprinklers, and all other hazards and risks, and in such
amounts, as described in the original Disclosure Schedule.

                  (b)      All such policies of insurance will be in such form,
with such companies, and in such amounts as reasonably satisfactory to Lender.
All such policies of property insurance will contain a lender's loss payable
endorsement, in a form satisfactory to Lender, showing Lender as an additional
loss payee thereof and all liability insurance policies will show the Lender as
an additional insured, and will specify that the insurer must give at least 20
days' notice to Lender before canceling its policy for any reason. Borrower will
deliver to Lender certified copies of such policies of insurance and evidence of
the payments of all premiums therefor. All proceeds payable under any such
policy will, at the option of Lender, be payable to Lender to be applied on
account of the Obligations.

         6.5      FURTHER ASSURANCES. At any time and from time to time Borrower
will execute and deliver such further instruments and take such further action
as may reasonably be requested by Lender to effect the purposes of this
Agreement.

perform, keep, or observe any other material term, provision, condition,

Documents, or in any other present or future agreement between Borrower and

been removed, discharged or rescinded within [*], or if Borrower is enjoined,
restrained, or in any way prevented by court order from continuing to conduct
all or any material part of its business affairs, or if a judgment or other
claim becomes a lien or encumbrance upon any material portion of Borrower's
assets, or if a notice of lien, levy, or assessment is filed of record with
respect to any of Borrower's assets by the United States Government, or any
department, agency, or instrumentality thereof, or by any state, county,

adequate bond has been posted pending a good faith contest by Borrower (provided
that no Advances will be required to be made during such cure period);

8.       LENDER'S RIGHTS AND REMEDIES.

         8.1      RIGHTS AND REMEDIES. Upon the occurrence and during the
continuance of an Event of Default, Lender may, at its election, without notice
of its election and without demand (but subject to FCC approval, if required),
do any one or more of the following, all of which are authorized by Borrower:

                  (a)      Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in
Section 7.4 all Obligations will become immediately due and payable without any
action by Lender);

                  (b)      Cease advancing money or extending credit to or for
the benefit of Borrower under this Agreement or under any other agreement
between Borrower and Lender;

                  (c)      Settle or adjust disputes and claims directly with
account debtors for amounts, upon terms and in whatever order that Lender
reasonably considers advisable;

                  (d)      Without notice to or demand upon Borrower, make such
payments and do such acts as Lender considers necessary or reasonable to protect
its security interest in the Collateral. Borrower agrees to assemble the
Collateral if Lender so requires, and to make the Collateral available to Lender
as Lender may designate. Borrower authorizes Lender to enter the premises where
the Collateral is located, to take and maintain possession of the Collateral, or
any part of it, and to pay, purchase, contest, or compromise any encumbrance,
charge, or lien which in Lender's determination appears to be prior or superior
to its security interest and to pay all expenses incurred in connection
therewith. With respect to any of Borrower's owned premises, Borrower hereby
grants Lender a license to enter into possession of such premises and to occupy
the same, without charge, for up to 120 days in order to exercise any of
Lender's rights or remedies provided herein, at law, in equity, or otherwise;

                  (e)      Without notice to Borrower set off and apply to the
Obligations any and all indebtedness at any time owing to or for the credit or
the account of Borrower held by Lender;

                  (f)      Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Collateral. Lender is hereby granted a license or other right,
solely pursuant to the provisions of this Section 8.1, to use, without charge,
Borrower's labels, patents, copyrights, rights of use of any name, trade
secrets,

trade names, trademarks, service marks, and advertising matter, or any property
of a similar nature, as it pertains to the Collateral, in completing production
of, advertising for sale, and selling any Collateral and, in connection with
Lender's exercise of its rights under this Section 8.1, Borrower's rights under
all licenses and all franchise agreements will inure to Lender's benefit;

                  (g)      Sell the Collateral at either a public or private
sale, or both, by way of one or more contracts or transactions, for cash or on
terms, in such manner and at such places (including Borrower's premises) as
Lender determines is commercially reasonable;

                  (h)      Lender may credit bid and purchase at any public
sale; and

                  (i)      Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

         8.2      POWER OF ATTORNEY. Effective only upon the occurrence and
during the continuance of an Event of Default, Borrower hereby irrevocably
appoints Lender (and any of Lender's designated officers, or employees) as
Borrower's true and lawful attorney to: (a) send requests for verification of
Accounts or notify account debtors of Lender's security interest in the
Accounts; (b) endorse Borrower's name on any checks or other forms of payment or
security that may come into Lender's possession; (c) sign Borrower's name on any
invoice or bill of lading relating to any Account, drafts against account
debtors, schedules and assignments of Accounts, verifications of Accounts, and
notices to account debtors; (d) make, settle, and adjust all claims under and
decisions with respect to Borrower's policies of insurance; and (e) settle and
adjust disputes and claims respecting the accounts directly with account
debtors, for amounts and upon terms which Lender determines to be reasonable;
provided Lender may exercise such power of attorney to sign the name of Borrower
on any of the documents described in Section 4.2 regardless of whether an Event
of Default has occurred. The appointment of Lender as Borrower's attorney in
fact, and each and every one of Lender's rights and powers, being coupled with
an interest, is irrevocable until all of the Obligations have been fully repaid
and performed and Lender's obligation to provide advances hereunder is
terminated.

         8.3      ACCOUNTS COLLECTION. Effective only upon the occurrence and
during the continuance of an Event of Default, Lender may notify any Person
owing funds to Borrower of Lender's security interest in such funds and verify
the amount of such Account. Borrower will collect all amounts owing to Borrower
for Lender, receive in trust all payments as Lender's trustee, and immediately
deliver such payments to Lender in their original form as received from the
account debtor, with proper endorsements for deposit.

         8.4      LENDER'S LIABILITY FOR COLLATERAL. So long as Lender complies
with reasonable business practices, Lender will not in any way or manner be
liable or responsible for: (a) the

safekeeping of the Collateral; (b) any loss or damage thereto occurring or
arising in any manner or fashion from any cause; (c) any diminution in the value
thereof; or (d) any act or default of any carrier, warehouseman, bailee,
forwarding agency, or other person whomsoever. All risk of loss, damage or
destruction of the Collateral will be borne by Borrower.

         8.5      REMEDIES CUMULATIVE. Lender's rights and remedies under this
Agreement, the Loan Documents, and all other agreements will be cumulative.
Lender will have all other rights and remedies not inconsistent herewith as
provided under the Code, by law, or in equity. No exercise by Lender of one
right or remedy will be deemed an election, and no waiver by Lender of any Event
of Default on Borrower's part will be deemed a continuing waiver. No delay by
Lender will constitute a waiver, election, or acquiescence by it. No waiver by
Lender will be effective unless made in a written document signed on behalf of
Lender and then will be effective only in the specific instance and for the
specific purpose for which it was given.

         8.6      DEMAND; PROTEST. Borrower waives demand, protest, notice of
protest, notice of default or dishonor, notice of payment and nonpayment, notice
of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Lender on which Borrower may in any way be
liable.

9.       INDEMNIFICATION.

         Borrower will defend, indemnify and hold harmless Lender and its
officers, employees, and agents against: (a) all obligations, demands, claims,
and liabilities claimed or asserted by any other party in connection with the
transactions contemplated by this Agreement; and (b) all losses or costs and
expenses in any way suffered, incurred, or paid by Lender as a result of or in
any way arising out of, following, or consequential to transactions between
Lender and Borrower whether under this Agreement, or otherwise (including
without limitation reasonable attorneys fees and expenses), except for losses
caused by Lender's gross negligence or willful misconduct.

10.      ADDITIONAL AGREEMENTS.
   

         10.1     BREACH BY LENDER. In the event Lender fails to make any
advance when due pursuant to this Agreement, and Lender fails to cure such
breach within [*] business days after Borrower gives Lender notice thereof,
Borrower will be entitled to [*]. The foregoing [*] will be suspended during
any period during which there exists a good faith dispute concerning the
compliance with the requirements of this Agreement of Borrower's request for
the Advance in question.
    

         10.2     TERMINATION OF OPTION AGREEMENT.

                  (a)      In the event Lender terminates the Option in
accordance with Section 1.4(b)(2) of the Option Agreement, Borrower terminates
the Option Agreement in accordance with Section 8.1(d) of the Option Agreement

aggregate amount of principal and accrued but unpaid interest then outstanding
minus (2) $350,000.

                  (c)      Any such termination fee may be paid, at the
