one hand, and the Collateral Agent and the Noteholders, on the other hand:

            (i)   the security interests and liens of SVB in the SVB Collateral

<PAGE>
            (iii) the provisions of clauses (i) and (ii) above shall be
      effective regardless of the times of creation, attachment or perfection of
      any of such security interests and liens or of the order of execution of

Loan Documents.

      2.2   Proceeds of SVB Collateral. Without limiting the provisions of
Section 2.3 hereof, any amounts received by the Collateral Agent or any
Noteholder on or as a result of any exercise of remedies under the Noteholder
Collateral Documents with respect to, or otherwise from the proceeds of a sale
or transfer or other disposition of, the SVB Collateral, or otherwise, shall be
paid over to SVB for application to the SVB Obligations in the manner provided
in the SVB Agreements.

      2.3   Limitations on Rights and Remedies. Neither the Collateral Agent nor
any Noteholder shall be entitled to exercise any rights or remedies with respect
to the SVB Collateral, including any right to (a) enforce any liens thereon or
sell or otherwise foreclose on any portion of the SVB Collateral or (b) request
any action, institute proceedings, give any instructions, make any election,
give any notice to account debtors or make collections with respect to any
portion of the SVB Collateral. The Collateral Agent will execute and deliver any
and all releases and other documents that SVB may reasonably request to give

any copy, statement or summary (or acquiesce in the publication or giving of any
such copy, statement or summary) as to the subordination hereunder of the lien
rights of the Collateral Agent, on behalf of the Noteholders, without also
stating or causing to be stated (in a conspicuous manner in the case of any
document) that such subordination is solely for the benefit of SVB and not for
the benefit of any other creditor of the Company or the Company.

      2.5   Rights of SVB Not to be Impaired. No right of SVB to enforce the
provisions hereof shall at any time in any way be prejudiced or impaired by any
act or omission in good faith by SVB or by any noncompliance by any other party
to this Agreement with the terms and provisions hereof or of any documents or
instruments relating to the Noteholder Obligations, regardless of any knowledge
thereof that SVB may have or otherwise be charged with.

                                       3

      2.6   Waivers. SVB shall not have any liability or duty of any kind to the
Collateral Agent or the Noteholders with respect to the SVB Collateral, except
as set forth in this Agreement. The Collateral Agent and the Noteholders hereby
waive and release any claim that any of them may now or hereafter have against
SVB arising out of any and all actions which it, in good faith, takes or omits
to take with respect to the SVB Collateral, including (a) actions with respect
to the creation, perfection or continuation of liens on or security interests in
such Collateral, (b) actions with respect to the foreclosure upon, sale, release
or disposition of, or failure to realize upon, any of such Collateral or (c) any
other action with respect to the enforcement of any provision with respect to
the SVB Collateral or the valuation, use, protection or disposition of such
Collateral. Notwithstanding the foregoing, SVB shall give the Collateral Agent
reasonable prior notice of any foreclosure upon or disposition of any SVB
Collateral by SVB.

      2.7   Remedies. The rights and remedies of SVB under the SVB Agreements
shall be cumulative and not exclusive of any rights or remedies which it would
otherwise have. No failure or delay by SVB in exercising any such right shall
operate as a waiver of such right, nor shall any partial or single exercise of
any such right preclude its other or further exercise or the exercise of any
other right.

      2.8   SVB's Rights. This is a continuing agreement of subordination of
Collateral Agent's and the Noteholders' security interests, and SVB may
continue, without notice to the Collateral Agent and the Noteholders, to extend
credit or other accommodations or benefits, and loan monies, to or for the
account of the Company in reliance hereon. SVB may at any time, in its
discretion, renew or extend the time of payment of all or any SVB Obligations,
amend or modify the SVB Obligations and any terms or provisions thereof
(including without limitation the rate of interest thereon) or of any agreement
securing the same or otherwise relating thereto, waive or release any SVB
Collateral which may be held therefor at any time, and make and enter into any
such agreement or agreements as SVB may deem proper or desirable relating to the
SVB Obligations, without notice to or further consent from the Collateral Agent
and the Noteholders; provided, however, that the aggregate principal amount of
the SVB Obligations shall not exceed $20,000,000 (plus interest and reasonable
costs, fees and expenses, including without limitation reasonable attorneys
fees) without the consent of the Collateral Agent. The Collateral Agent and the
Noteholders waive notice of acceptance hereof, notice of the creation of any SVB
Obligations, the giving or extension of any credit by SVB to the Company, or the
taking, waiving or releasing of any security therefor, or the making of any
modifications to any SVB Agreements (except as provided in the second sentence
of this Section 2.8), and the Collateral Agent and the Noteholders waive
presentment, demand, protest, notice of protest, notice of default, and all
other notices to which the Collateral Agent and the Noteholders might otherwise
be entitled, except as herein expressly set forth.

      2.9   Agreement Not to Transfer Notes Without Consent. Each Noteholder
agrees that it will not transfer any Note held by it without causing the
transferee or assignee to execute a written acknowledgment accepting the terms
and conditions of this Agreement.

      2.10  Receipt in Trust. In the event that, notwithstanding the foregoing,
any payment shall be made to the Collateral Agent or a Noteholder that is not
permitted by Section 2.2 hereof, such payment shall be received and held in
trust for SVB and shall be paid over and delivered

                                       4
<PAGE>
forthwith to SVB or its representative for application to the SVB Obligations in
the manner provided in the SVB Agreements.

      2.11  Company Agreement. The Company agrees that any Event of Default
shall constitute a default and an event of default under the SVB Agreements.

      SECTION 3 Intercreditor Arrangements in Bankruptcy.

      (a)   This Agreement shall remain in full force and effect and enforceable
pursuant to its terms in accordance with Section 510(a) of the Bankruptcy Code,
and all references herein to the Company shall be deemed to apply to such entity
as debtor in possession and to any trustee in bankruptcy for the estate of such
entity.

      (b)   Except as otherwise specifically permitted in this Section 3, until
the SVB Obligations have been paid in full and all financing commitments under
the SVB Agreements have expired or been terminated, the Collateral Agent will
not assert, without the written consent of SVB, any claim, motion or objection
in respect of the SVB Collateral or the Noteholder Collateral in connection with
any Bankruptcy Event (other than a claim or assertion that SVB has acted in bad
faith or in violation of law) which could otherwise be asserted or raised in
connection with such Bankruptcy Event by the Collateral Agent or a Noteholder as
a creditor of the Company, including without limitation any claim, motion or
objection seeking or opposing adequate protection or relief from the automatic
stay in respect of the SVB Collateral or the Noteholder Collateral.

      (c)   Without limiting the generality of the foregoing, the Collateral
Agent agrees that if a Bankruptcy Event occurs, (i) SVB may consent to the use
of cash collateral on such terms and conditions and in such amounts as it shall
in good faith determine without seeking or obtaining the consent of the
Collateral Agent or the Noteholders as holders of an interest in the Noteholder
Collateral; (ii) SVB may provide postpetition financing for the Company pursuant
to Section 364 of the Bankruptcy Code or other applicable law and on such terms
and conditions and in such amounts as it shall in good faith determine without
seeking or obtaining the consent of the Collateral Agent or the Noteholders as
holders of an interest in the Noteholder Collateral, and neither the Collateral
Agent nor the Noteholders shall oppose such financing; (iii) neither the
Collateral Agent nor the Noteholders shall oppose the Company's use of cash
collateral on the basis that their interest in the Noteholder Collateral is
impaired by such use or inadequately protected by such use to the extent such
use has been approved by SVB in good faith; and (iv) neither the Collateral
Agent nor the Noteholders shall oppose any sale or other disposition of any
assets comprising part of the Noteholder Collateral free and clear of security
interests and liens of any party, including the Noteholders, under Section 363
of the Bankruptcy Code on the basis that the interest of the Noteholders in the
Noteholder Collateral is impaired by such sale or inadequately protected as a
result of such sale if SVB has consented in good faith to such sale or
disposition of such assets.

      (d)   The Collateral Agent agrees that it will not initiate or prosecute
any claim, action or other proceeding (i) challenging the validity or
enforceability of the SVB Agreements, (ii) challenging the validity,
enforceability or unavoidability of any claim of SVB with respect to the SVB
Collateral, (iii) challenging the perfection, enforceability or unavoidability
of any liens

                                       5
<PAGE>
securing the SVB Collateral or (iv) asserting any such claims which the Company
may hold with respect to SVB or the SVB Obligations.

      (e)   To the extent that SVB receives payments or transfers on the SVB
Obligations or proceeds of the SVB Collateral which are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to a trustee, receiver or any other party under any
bankruptcy or other applicable law, then, to the extent of such payment or
proceeds received, the SVB Obligations, or part thereof, intended to be
satisfied shall be revived and continue in full force and effect enjoying all
rights and benefits of this Agreement as if such payments or proceeds had not
been received by SVB.

      (f)   Notwithstanding any other provision of this Section 3, the
Collateral Agent and each Noteholder shall be entitled to file any necessary
responsive or defensive pleadings in opposition to any motion, claim, adversary
proceeding or other pleading made by any person objecting to or otherwise
seeking the disallowance of the claims of the Noteholders, including without
limitation any claims secured by the Noteholder Collateral, or challenging the
perfection, enforceability or unavoidability of any liens securing the
Noteholder Collateral.

      SECTION 4 Miscellaneous.

full of the SVB Obligations and expiration or termination of the financing
commitments under the SVB Agreements, promptly execute, deliver and file any and
all further instruments and documents necessary to evidence the termination of

            Equivalents with Bank and Bank's affiliates in an amount nor less
            than $8,000,000; provided that a failure to do so shall not
            constitute an Event of Default hereunder if, at all times that
            Borrower fails to meet said covenant Borrower has a Quick Ratio of
            at least 5.0 to 1. If at any time Borrower fails to have Cash and

            time, (a) any evidence of indebtedness with a maturity date of

            commercial paper (including variable rate demand notes) with a
            maturity of ninety (90) days or less issued by a corporation (except

                  (3)   As used herein. `Quick Ratio' means the ratio of (i) the
            total of Borrower's Cash, Cash Equivalents and Accounts which are,
            in Bank's discretion, eligible for borrowing, to (ii) Borrower's
            Current Liabilities. As used herein, `Current Liabilities' means
            current liabilities in accordance with generally accepted accounting
            principles, and all indebtedness, liabilities, guarantees and other
            obligations of the Borrower to Bank, including without limitation
            those relating to cash management services, letters of credit and
            foreign exchange contracts."

            3.4 SOQUEL LEASE. A new Section 13A is hereby added to the Accounts
Agreement as follows:

            "13A. Bank consents to Borrower (i) terminating its lease of the
            Soquel real property, (ii) purchasing said real property, and (iii)
            in connection with said purchase, assuming a mortgage on said real
            property with an unpaid balance of approximately $3,200.000. This
            consent does not constitute a consent to any other action by
            Borrower (whether or not similar to the foregoing)."

that all representations and warranties set forth in the Loan Agreement, as
amended hereby, are true and correct.

      5.    GENERAL PROVISIONS. This Amendment, the Loan Agreement, any prior
written amendments to the Loan Agreement signed by Silicon and Borrower, and the

agreements and understandings between the parties with respect to the subject
hereof. Except as herein expressly amended, all of the terms and provisions of
the Loan Agreement, and all other documents and agreements between Silicon and
Borrower shall continue in full force and effect and the same are hereby
ratified and confirmed.

                    EXHIBIT A TO AMENDMENT TO LOAN DOCUMENTS

                              OVERADVANCE LC RIDER

      This Overadvance LC Rider is attached to and forms a part of the Accounts
Receivable Financing Agreement dated as of June 13, 2003 (the "Accounts
Agreement") between Proxim Corporation ("Borrower") and Silicon Valley Bank
("Bank").

      1.    Overadvances LCs.

            (a)   Bank may, in its good faith business judgment, provide
Borrower with Letters of Credit in excess of the formulas set forth in the
Accounts Agreement (the "Overadvance LCs"), as set forth in this Rider. (If a
Letter of Credit is 100% secured by cash or is 100% reserved for from Advances
which would otherwise be available to the Borrower under the Accounts Agreement
(after all other reserves), such Letter of Credit will not be deemed an
Overadvance LC. If only part of the face amount of a Letter of Credit is
secured by cash or is so reserved, then such Letter of Credit shall only be
deemed an Overadvance LC to the extent such Letter of Credit is not cash secured
and not covered by such reserves.)

            (b)   The unpaid balance of all Overadvance LCs from time to time
outstanding shall not at any time exceed $4,000,000, and in the event it does,
at any time, Borrower will provide Bank with cash collateral in an amount equal
to 100% of the excess immediately, without notice or demand.

            (c)   In no event shall the total Obligations (including without
limitation the Overadvance LCs) exceed $20,000,000.

      2.    Overadvance Maturity Date.

            (a)   Overadvance LCs may be outstanding only during the period from
the date hereof to the earlier of the following (the "Overadvance Maturity
Date"): July 31, 2004 or the date the Accounts Agreement terminates by its terms
or is terminated by any party in accordance with its terms.

            (b)   On and after the Overadvance Maturity Date, the Overadvance
facility established by this Rider will expire, and no further Overadvance LCs
will be issued. On or before the Overadvance Maturity Date, Borrower shall
provide Bank with cash collateral in an amount equal to 100% of the face amount
of all outstanding Overadvance LCs (including without limitation drawn, but
unreimbursed Overadvance LCs). All cash collateral provided pursuant to this
Rider shall be held as "Collateral" for all purposes of the Accounts Agreement.
In the event, on the Overadvance Maturity Date, Borrower fails to provide Bank
with cash collateral in an amount equal to 100% of the face amount of all
outstanding Overadvance LCs, such failure shall constitute an Event of Default
under the Accounts Agreement,

SILICON VALLEY BANK                                  AMENDMENT TO LOAN DOCUMENTS

      3.    Fees. Borrower shall pay all standard charges with respect to
Overadvance LCs as are charged by Bank's international Department.

      4.    Collateral. The Obligation to reimburse Bank for all Overadvance
LCs, and all of Borrower's other obligations under this Rider shall for all
purposes be deemed "Obligations" under the Accounts Agreement and shall be
secured by all of the Collateral. All Overadvance LCs shall, for all purposes,
be deemed to be "Letters of Credit" under the Accounts Agreement, and all
Overadvance LCs shall be entitled to all of the benefits of, and (except as
herein expressly set forth) shall be subject to all of the terms and provisions
of, all of the Loan Documents.
