                                LOAN AGREEMENT



THIS LOAN AGREEMENT is entered into as of October 14, 1997 (this "Loan
Agreement") between METAWAVE COMMUNICATIONS CORPORATION, a Delaware corporation
(herein called "Borrower"), and IMPERIAL BANK (herein called "Bank").

     1.   COMMITMENT.

          A.   FACILITY-A COMMITMENT.  Subject to all the terms and conditions
of this Loan Agreement and prior to the termination of its commitment as
hereinafter provided, Bank hereby agrees to make loans (each a "Facility-A
Loan") to Borrower, from time to time and in such amounts as Borrower shall
request pursuant to this SECTION 1.A., up to an aggregate principal amount
outstanding under the Facility-A Loan Account (as hereinafter defined) not to
exceed the least of:  (a) Eighty percent (80%) of Eligible Accounts (the
"Borrowing Base") or (b) $5,000,000.00 (the "Facility-A Commitment").  If at any
time or for any reason, the outstanding principal amount of the Facility-A Loan
Account is greater than the least of:  (x) the Borrowing Base or (y) the
Facility-A Commitment, Borrower shall immediately pay to Bank, in cash, the
amount of such excess.  Any commitment of Bank, pursuant to the terms of this
Loan Agreement, to make Facility-A Loans shall expire on the Facility-A Maturity
Date (as hereinafter defined), subject to Bank's right to renew said commitment
in its sole and absolute discretion at Borrower's request.  Any such renewal of
said commitment shall not be binding upon Bank unless it is in writing and
signed by an officer of Bank.  Provided that no Event of Default (as hereinafter
defined) has occurred and is continuing, all or any portion of the Facility-A
Loans advanced by Bank which are repaid by Borrower shall be available for
reborrowing in accordance with the terms hereof.  Borrower promises to pay to
Bank the entire outstanding unpaid principal balance (and all accrued unpaid
interest thereon) of the Facility-A Loan Account on October 14, 1999 ("Facility-
A Maturity Date").

               (1)  FACILITY-A LOANS. The amount of each Facility-A Loan made by
Bank to Borrower hereunder shall be debited to the loan ledger account of
Borrower maintained by Bank for the Facility-A Commitment (herein called the
"Facility-A Loan Account") and Bank shall credit the Facility-A Loan Account
with all loan repayments in respect thereof made by Borrower. When Borrower
desires to obtain a Facility-A Loan, Borrower shall notify Bank (which notice
shall be signed by an officer of Borrower and shall be irrevocable) in
accordance with SECTION 2 hereof, to be received no later than 3:00 p.m. Pacific
time one (1) Banking Day (as hereinafter defined) before the day on which the
Facility-A Loan is to be made. Facility-A Loans may only be used for working
capital purposes and the issuance of letters of credits.

                    (a)  LETTER OF CREDIT USAGE AND SUBLIMIT. Subject to the
availability of the Facility-A Commitment and in reliance on the representations
and warranties of Borrower set forth herein, at any time and from time to time
from the date hereof through the Banking Day immediately prior to the Facility-A
Maturity Date, Bank shall issue for the account of Borrower such standby and
commercial letters of credit ("Letters of Credit") as Borrower may request,
which request shall be made by delivering to Bank a duly executed letter of
credit application on Bank's standard form; provided, however, that the
outstanding and undrawn amounts under all such Letters of Credit (i) shall not
at any time exceed $3,000,000.00 and (ii) shall be deemed to constitute
Facility-A Loans for the purpose of calculating availability under the
Facility-A Commitment. Unless Borrower shall have deposited with Bank cash
collateral in an amount sufficient to cover all undrawn amounts under each such
Letter of Credit and Bank shall have agreed in writing, no Letter of Credit
shall have an expiration date that is later than the Facility-A Maturity Date.
All Letters of Credit shall be in form and substance acceptable to Bank in its
sole discretion and shall be subject to the terms and conditions of Bank's
application and letter of credit agreement, in the form of EXHIBIT B attached
hereto and incorporated herein by this reference. Borrower will pay any standard
issuance and other fees that Bank notifies Borrower will be charged for issuing
and processing Letters of Credit for Borrower.

               (2)  LIMITATION ON ADVANCE OF ANY FACILITY-A LOAN.
Notwithstanding any of the provisions contained in SECTION 1.A hereof, prior to
any advance of a Facility-A Loan, a representative of Bank shall have conducted
an audit of Borrower's books and records relating to the Collateral and made
extracts therefrom, and arranged for verification of the Accounts, directly with
the account debtors or otherwise, all with results reasonably satisfactory to
Bank, the cost of such audit of which shall be at Borrower's sole expense. Based
on Bank's review of such audit, and prior to the advance of a

THE OMITTED PORTIONS.


<PAGE>

Facility-A Loan in accordance with the terms of SECTION 1.A hereof, Bank may
adjust the Borrowing Base percentage, in its sole and reasonable discretion, as
provided for under SECTION 9.B. hereof.

               (3)  NON-FORMULA AVAILABILITY. Provided that no Event of Default
has occurred and is continuing, and subject to the availability of the Facility-
A Commitment and in reliance on the representations and warranties of Borrower
set forth herein, at any time from the date hereof through April 30, 1998, Bank
hereby agrees to make Facility-A Loans to Borrower in such amounts as Borrower
shall request pursuant to this SECTION 1.A.(3), in an aggregate principal amount
not to exceed $2,500,000.00 (the "Non-Formula Availability"); provided, however,
that the outstanding amounts under this Non-Formula Availability shall be deemed
to constitute Facility-A Loans for the purpose of calculating availability under
the Facility-A Commitment.

               (4)  INTEREST PAYMENTS ON FACILITY-A LOANS. Borrower further
promises to pay to Bank from the date of the advance of the initial Facility-A
Loan through the Facility-A Maturity Date, on or before the tenth (10th) day of
each month, interest on the average daily unpaid balance of the Facility-A Loan
Account during the immediately preceding month at a rate of interest equal to
the rate of interest per annum which Bank has announced as its prime lending
rate (the "Prime Rate"), which shall vary concurrently with any change in the
Prime Rate. Interest shall be computed at the above rate on the basis of the
actual number of days during which the principal balance of the Facility-A Loan
Account is outstanding divided by 360, which shall for interest computation
purposes be considered one (1) year.

     2.   LOAN REQUESTS.  Requests for Loans hereunder shall be in writing duly
executed by Borrower in the form of EXHIBIT C attached hereto and incorporated
herein by this reference and shall contain a certification setting forth the
matters referred to in SECTION 1, which shall disclose that Borrower is entitled
to the amount and type of Loan being requested.  Bank is hereby authorized to
charge Borrower's deposit account with Bank for all principal and interest due
Bank under this Loan Agreement.

     3.   DELIVERY OF PAYMENTS.  Payment to Bank of all amounts due hereunder
shall be made at its Santa Clara Valley Regional office, or at such other place
as may be designated in writing by Bank from time to time.  If any payment date
fall on a day that is not a day that Bank is open for the transaction of
business ("Banking Day"), the payment due date shall be extended to the next
Banking Day.

     4.   LATE CHARGE.  If any interest payment, principal payment or principal
balance payment required hereunder is not received by Bank on or before ten (10)
days from the date in which such payment becomes due, Borrower shall pay to
Bank, a late charge equal to the lesser of (a) five percent (5.0%) of the amount
of such unpaid payment, in addition to said unpaid payment or (b) the maximum
amount permitted to be charged by applicable law, until remitted to Bank;
provided; however, nothing contained in this SECTION 4, shall be construed as
any obligation on the part of Bank to accept payment of any past due payment or
less than the total unpaid principal balance of the Facility-A Loan Account
following the FacilityA Maturity Date.  All payments shall be applied first to
any late charges due hereunder, next to accrued interest then payable and the
remainder, if any, to reduce any unpaid principal due under the Facility-A Loan
Account.

     5.   DEFAULT INTEREST.  From and after the Facility-A Maturity Date, or
such earlier date as all sums owing under the Facility-A Loan Account becomes
due and payable by acceleration or otherwise, or upon the occurrence of an Event
of Default, at the option of Bank all sums owing under the Facility-A Loan
Account shall bear interest until paid in full at a rate equal to the lesser of
(a) five percent (5.0%) per annum in excess of the then applicable interest rate
provided for in SECTION 1.A.(3) hereof or (b) the maximum amount permitted to be
charged by applicable law, until all obligations hereunder are repaid in full or
the Event of Default is waived or cured to the satisfaction of Bank, as
applicable.

defined herein, all initially capitalized terms shall have the meanings set
forth on EXHIBIT A attached hereto and incorporated herein by this reference.

have hereunder or by law. If a sufficient sum is not realized from any such
disposition of the Collateral to pay all obligations secured by this Loan
Agreement, Borrower hereby promises and agrees to pay Bank any deficiency.

costs of the court reporter at the trial shall be borne equally by the parties.

               (3)  The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted,  is also to be a reference proceeding
under this provision.

               (4)  In the event that the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted),
any dispute between the parties that would otherwise be determined by the
reference procedure herein described will be resolved and determined by
arbitration. The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, (S) 1280 through (S) 1294.2
of the CCP as amended from time to time. The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration
