Pursuant
to Section 151 of the
General Corporation Law of the State of Delaware

The
undersigned, pursuant to the provisions of Section 151 of the General Corporation Law of the State of Delaware, does hereby certify that, pursuant to the authority expressly
vested in the Board of Directors of Proxim Corporation, a Delaware corporation (the "CORPORATION"), by the Corporation's Certificate of Incorporation, the Board of Directors of the Corporation (the
"BOARD OF DIRECTORS") has duly provided for the issuance of and created a series of Preferred Stock (the "PREFERRED STOCK") of the Corporation, par value $.01 per share, and in order to fix the
designation and amount and the voting powers, designations, preferences and relative, participating, optional and other special rights, and the qualifications, limitations and restrictions, of a
series of Preferred Stock, has duly adopted this "Certificate of Designations, Preferences and Rights of Series C Preferred Stock of Proxim Corporation" (the "CERTIFICATE"). All capitalized
terms not defined above or in Sections 1 through 10 below are defined in Section 11 herein.

Each
share of such series of Preferred Stock shall rank equally in all respects and shall be subject to the following provisions:

1.     NUMBER
OF SHARES AND DESIGNATION. 400,000 shares of Preferred Stock of the Corporation shall constitute a series of Preferred Stock designated as Series C
Preferred Stock (the "SERIES C PREFERRED STOCK"). The number of shares of Series C Preferred Stock may be increased (to the extent of the Corporation's authorized and unissued Preferred Stock)
or decreased (but not below the number of shares of Series C Preferred Stock then outstanding) by further resolution duly adopted by the Board of Directors and the filing of a certificate
reflecting such increase or decrease, as the case may be, with the Secretary of State of the State of Delaware.

2.     RANK.
The Series C Preferred Stock shall, with respect to redemption payments, rights upon liquidation, dissolution or winding up of the affairs of the
Corporation, or otherwise (i) rank senior and prior to the Common Stock, the Series A Preferred Stock, the Series B Preferred Stock and each other class or series of equity
securities of the Corporation, whether currently issued or issued in the future, that by its terms ranks junior to the Series C Preferred Stock (whether with respect to redemption payments,
rights upon liquidation, dissolution or winding up of the affairs of the Corporation, or otherwise) (all of such equity securities, including the Series A Preferred Stock, Series B
Preferred Stock and Common Stock, are collectively referred to herein as the "JUNIOR SECURITIES"), (ii) rank on a parity with each other class or series of equity securities of the Corporation,
whether currently issued or issued in the future, that does not by its terms expressly provide that it ranks senior to or junior to the Series C Preferred Stock (whether with respect to payment
of redemption payments, rights upon liquidation, dissolution or winding up of the affairs of the Corporation, or otherwise) (all of such equity securities are collectively referred to herein as the
"PARITY SECURITIES"), and (iii) rank junior to each other class or series of equity securities of the Corporation, whether currently issued or issued in the future, that by its terms ranks
senior to the Series C Preferred Stock (whether with respect redemption payments, rights upon liquidation, dissolution or winding up of the affairs of the Corporation, or otherwise) (all of
such equity securities are collectively referred to herein as the "SENIOR SECURITIES"). The respective definitions of Junior Securities, Parity Securities and Senior Securities shall also include any
rights or options exercisable or exchangeable for or convertible into any of the Junior Securities, Parity Securities or Senior Securities, as the case may be.

3.     DIVIDENDS.

(a)   The
holders of shares of Series C Preferred Stock shall not be entitled to receive dividends on the Series C Preferred Stock.

---



(b)   From
and after the time, if any, that the Corporation fails to pay to the holder of any shares of Series C Preferred Stock, on the date specified for redemption
in accordance with Section 5, Section 6 or Section 7 hereof or on the date specified for repurchase in accordance with Section 10, the redemption price calculated pursuant
to Section 5, the Change of Control Price (as defined below) or the Material Asset Sale Price (as defined below) after such holder has delivered notice to the Corporation pursuant
Section 10 of its intention to exercise its repurchase rights under Section 10, if applicable, then (i) no dividends shall be declared or paid or set apart for payment, or other
distribution declared or made, upon any Junior Securities, nor shall any Junior Securities be redeemed, purchased or otherwise acquired (other than a redemption, purchase or other acquisition of
shares of Common Stock expressly required and made for purposes of any employee incentive or benefit plans or arrangements of the Corporation or any subsidiary of the Corporation or the payment of
cash in lieu of fractional shares in connection therewith) for any consideration (nor shall any moneys be paid to or made available for a sinking fund for the redemption of any shares of any such
Junior Securities) by the Corporation, directly or indirectly (except by conversion into or exchange for Junior Securities or the payment of cash in lieu of fractional shares in connection therewith)
and (ii) the Corporation shall not, directly or indirectly, make any payment on account of any purchase, redemption, retirement or other acquisition of any Parity Securities (other than for
consideration payable solely in Junior Securities or the payment of cash in lieu of fractional shares in connection therewith); provided, however, that this Section 3(b) shall not be applicable
at any time that (A) the Corporation has irrevocably paid, in accordance with Section 5 or Section 7, the entire redemption price payable to each holder of Series C
Preferred Stock, (B) the Corporation has irrevocably paid, in accordance with Section 6, the Change of Control Price payable to each holder or (C) the Corporation has irrevocably
paid, in accordance with Section 10, the Material Asset Sale Price payable to each holder that has exercised its repurchase right pursuant to Section 10.

4.     LIQUIDATION
PREFERENCE.

(a)   The
initial liquidation preference for the shares of Series C Preferred Stock shall be $100.00 per share (the "STATED VALUE"), which amount shall accrete from the
Original Issue Date (as defined below) at an annual rate of 8.75%, compounded quarterly, computed on the basis of a 360-day year of twelve 30-day months (such accreted amount
being the "LIQUIDATION VALUE"). Notwithstanding the foregoing, in the event of a Change of Control (as defined below) or a Material Asset Sale (as defined below), the Liquidation Value upon such
Change of Control or Material Asset Sale, as the case may be, shall be increased by the amount, if any, by which (i) the amount of the Liquidation Value if it had fully accreted from the Change
of Control Date (as defined below) or Material Asset Sale Date (as defined below), as the case may be, through the eighth anniversary of the Original Issue Date exceeds (ii) the Liquidation
Value in effect immediately prior to the adjustment pursuant to this Section 4(a). The Stated Value shall be subject to appropriate adjustment in the event of any stock dividend, stock split,
stock distribution or combination, subdivision, reclassification or other corporate actions having a similar effect with respect to the Series C Preferred Stock (each, a "Capital Stock
Adjustment").

(b)   In
the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of shares of Series C Preferred Stock shall be
entitled to receive the Liquidation Value of such shares in effect on the date of such liquidation, dissolution or winding up, plus an amount equal to the unrecognized accretion, if any, from the end
of the most recent quarter ending October 22, January 22, April 22, or July 22, up to but not including the date of such liquidation, dissolution or winding up.

(c)   In
the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of shares of Series C Preferred Stock
(i) shall not be entitled to receive the Liquidation Value of such shares until payment in full or provision has been made for the payment in full of all claims of creditors of the Corporation
and the liquidation preferences for all Senior

2

---



Securities,
and (ii) shall be entitled to receive the Liquidation Value of such shares before any payment or distribution of any assets of the Corporation shall be made or set apart for holders
of any Junior Securities. Subject to clause (i) above, if the assets of the Corporation are not sufficient to pay in full the Liquidation Value payable to the holders of shares of
Series C Preferred Stock and the liquidation preference payable to the holders of any Parity Securities, then such assets, or the proceeds thereof, shall be distributed among the holders of
shares of Series C Preferred Stock and any such other Parity Securities ratably in accordance with the Liquidation Value for the Series C Preferred Stock and the liquidation preference
for the Parity Securities, respectively.

(d)   Neither
a consolidation or merger of the Corporation with or into any other entity, nor a merger of any other entity with or into the Corporation, nor a sale or transfer
of all or any part of the Corporation's assets for cash, securities or other property shall be considered a liquidation, dissolution or winding up of the Corporation within the meaning of this
Section 4.

5.     MANDATORY
REDEMPTION; PROCEDURES FOR REDEMPTION.

(a)   On
October 22, 2012, the Corporation shall redeem all outstanding shares of Series C Preferred Stock, if any, at a cash redemption price equal to the
Liquidation Value as if the Series C Preferred Stock had fully accreted through such date, after taking into account any Capital Stock Adjustments (such amount being referred to herein as the
"REDEMPTION PRICE"). In the event that the Corporation does not pay the Redemption Price on the Redemption Date, the Redemption Price shall be calculated as if the Redemption Date were the later of
the Redemption Date and the date on which such payment is made. If the Corporation is unable at the Redemption Date to redeem any or all shares of Series C Preferred Stock then to be redeemed
because such redemption would violate the applicable laws of the State of Delaware, then the Corporation shall redeem such shares as soon thereafter as redemption would not violate such laws. In the
event of any redemption of only a part of the then outstanding Series C Preferred Stock, the Corporation shall effect such redemption pro rata among the holders thereof (based on the number of
shares of Series C Preferred Stock held on the date of notice of redemption).

(b)   In
the event of a redemption of shares of Series C Preferred Stock pursuant to Section 5(a), Section 6 or Section 7, notice of such
redemption shall be given by the Corporation, by first class mail, postage prepaid, mailed not less than 15 days nor more than 45 days prior to the Redemption Date, to each holder of
Series C Preferred Stock at the address appearing in the Corporation's records. Such notice shall state: (i) the date on which the holder is to surrender to the Corporation the
certificates for any shares to be redeemed (such date, or if such date is not a Business Day, the first Business Day thereafter, the "REDEMPTION DATE") and (ii) the number of shares of
Series C Preferred Stock to be redeemed and, if fewer than all the shares held by such holder are to be redeemed, the number of shares to be redeemed from such holder (such notice being
referred to as the "REDEMPTION NOTICE"). On or prior to the Redemption Date, each holder of Series C Preferred Stock to be redeemed shall surrender his, her or its certificate or certificates
representing such shares to the Corporation, in the manner and at the place designated in the Redemption Notice, and thereupon the Redemption Price of such shares shall be payable to the order of the
person whose name appears on such certificate or certificates as the owner thereof and each surrendered certificate shall be canceled. In the event less than all the shares represented by any such
certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. From and after the Redemption Date, unless there shall have been a default in payment of the Redemption
Price, all rights of the holders of the Series C Preferred Stock (except the right to receive the Redemption Price without interest upon surrender of their certificate or certificates) shall
cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the Corporation or deemed to be outstanding for any purpose whatsoever.

as provided in this Section 5, Section 6 and Section 7, the Corporation shall have no right to redeem the shares of Series C Preferred
Stock. Any shares of Series C Preferred Stock so redeemed shall be permanently retired, shall no longer be deemed outstanding and shall not under any circumstances be reissued, and the
Corporation may from time to time take such appropriate corporate action as may be necessary to reduce the authorized Series C Preferred Stock accordingly.

6.     CHANGE
OF CONTROL; PROCEDURES UPON CHANGE OF CONTROL. In the event that the Corporation undergoes a Change of Control (the date of such occurrence being the "CHANGE OF
CONTROL DATE"), the Corporation shall be required to redeem in cash or readily marketable securities all outstanding shares of Series C Preferred Stock, if any, at a redemption price (the
"CHANGE OF CONTROL PRICE") equal to the Liquidation Value as if the Series C Preferred Stock had fully accreted through the eighth anniversary of the Original Issuance Date (after taking into
account any Capital Stock Adjustments, plus following the eighth anniversary of the Original Issue Date, an amount equal to the unrecognized accretion, if any, from the end of the immediately
preceding quarter ending October 22, January 22, April 22, or July 22, to but not including the Redemption Date. In the event of a redemption pursuant to this
Section 6, the Corporation shall follow the redemption procedures set forth in Section 5.

7.     OPTIONAL
REDEMPTION. At any time prior to October 22, 2012, the Corporation shall have the right at its option to redeem all outstanding shares of Series C
Preferred Stock at a price per share in cash equal to the Liquidation Value as if it had fully accreted through the eighth anniversary of the Original Issuance Date. The Corporation shall also have
the right at its option to redeem all outstanding shares of Series C Preferred Stock (i) at any time prior to, and including, the third anniversary of the Original Issuance Date at a
price per share in cash equal to its then accreted Liquidation Value (after taking into account any Capital Stock Adjustments), if the Market Price of the Common Stock has been higher than TWO DOLLARS
AND TWENTY-FIVE CENTS ($2.25) for a period of forty-five (45) consecutive trading days prior to the date of the applicable Redemption Notice or (ii) at any time
following the third anniversary of the Original Issuance Date at a price per share equal to its then accreted Liquidation Value (after taking into account any Capital Stock Adjustments), if the Market
Price of the Common Stock has been higher than TWO DOLLARS ($2.00) for a period of forty-five (45) consecutive trading days prior to the date of issuance of the applicable
Redemption Notice. In the event of a redemption pursuant to this Section 7, the Corporation shall follow the redemption procedures set forth in Section 5.

repurchased pursuant to Section 10 and all shares of Series C Preferred Stock that are otherwise reacquired by the Corporation shall (upon compliance with any applicable provisions of
the laws of the State of Delaware) have the status of authorized but unissued shares of Preferred Stock, without designation as to series, subject to reissuance by the Board of Directors as shares of
any one or more other series.

the Corporation in accordance with Section 5, Section 6, Section 7 or Section 10, as the case may be, and the funds necessary for such redemption or repurchase shall have
been set aside.
