              RE:  $29,000,000 13.75% SENIOR SECURED BRIDGE NOTES

                              DUE APRIL 28, 2000



                                                      Dated as of April 27, 1998

To the Purchasers named in Schedule I attached hereto that are signatories to
this Agreement

Ladies and Gentlemen:

     The undersigned, Metawave Communications Corporation, a Delaware
corporation (the "Company") agrees with each Purchaser as follows:

SECTION 1. DESCRIPTION OF NOTES; COMMITMENT; WARRANTS.

     Section 1.1.   Description of Notes.  The Company will authorize the issue
and sale of $29,000,000 aggregate original principal amount of its 13.75% Senior
Secured Bridge Notes due April 28, 2000 (the "Notes") to be dated the date of
issue.  Interest on the Notes will accrue at the lower of (i) 13.75% per annum
(as adjusted pursuant to the next succeeding sentence, the "Base Interest Rate")
and (ii) the highest rate permitted by law (such lower amount being referred to
as the "Interest Rate"), and will be payable semi-annually on April 28th and
October 28th of each year, commencing on October 28, 1998, and at maturity.  On
the twelve-month anniversary of the Closing Date, and at the end of each
subsequent one hundred eighty (180) day period, the Base Interest Rate will
increase by 200 basis points, up to a maximum Base Interest Rate of 18.0%.  The
interest shall be payable at the option of the Company (x) in kind by the
issuance to the holders thereof of separate promissory notes (each an "Interest
Note," and, collectively, the "Interest Notes"), in each case having a principal
amount equal to the amount of interest due and payable on such holder's
outstanding Notes on such interest payment date, or (y) in cash; provided that
                                                                 --------
the Company will only be entitled to pay such interest in cash if it has
irrevocably notified in writing the holders of the Notes of its intention to
make a cash interest payment at least ten (10) Business Days before the relevant
interest payment date, it being agreed that payment in kind via Interest Notes
is the default interest payment method in the absence of such notice.  Interest
on Interest Notes shall accrue at the same Interest Rate per annum and shall be
payable in kind by the issuance of additional Interest Notes or in cash as
provided above on the same date as interest is payable in kind or in cash as
provided above on the Notes.  The unpaid principal balance of all Notes
(including Interest Notes), together with accrued but unpaid interest thereon,
shall be due and payable in cash on the stated date of maturity of the Notes.

 
Notwithstanding different issue dates, unless the context clearly requires
otherwise, all Interest Notes shall be Notes for all purposes of this Agreement.
The Notes will bear interest on overdue principal (including any overdue
required or optional prepayment of principal) and premium, if any, and (to the
extent legally enforceable) on any overdue installment of interest at the
Interest Rate from the date such payment is due, whether by acceleration or
otherwise, until paid.  The Notes (including the Interest Notes) will mature on
April 28, 2000, and will be substantially in the form attached hereto as Exhibit
A.  Interest on the Notes shall accrue and be computed semi-annually on the
basis of a 360-day year of twelve 30-day months.  The term "Notes" as used
herein shall include each Note (including each Interest Note) delivered at any
time pursuant to this Agreement.  The terms that are capitalized herein shall
have the meanings set forth in Section 8.1 hereof unless the context shall
otherwise require or unless they are defined elsewhere herein.  The Notes
(including Interest Notes) will be senior secured obligations of the Company,
ranking pari passu in right of payment with all permitted existing and permitted
        ---- -----
future senior secured Indebtedness of the Company and senior to all unsecured or
subordinated Indebtedness of the Company, all non-permitted senior secured
indebtedness of the Company and all other senior indebtedness of the Company.

     Section 1.2.   Commitment, Closing Date.  Subject to the terms and
conditions hereof and on the basis of the representations and warranties
hereinafter set forth in this Agreement and in Exhibit C hereto, the Company
agrees to issue and sell to each Purchaser, and each Purchaser agrees to
purchase from the Company, the aggregate principal amount of Notes set forth
opposite such Purchaser's name on Schedule I attached hereto by delivery of the
Purchase Price for such Notes as set forth on Schedule I.  On the Closing Date
(as defined below), the Company also shall deliver to the Purchasers, pro rata
                                                                      --- ----
in proportion to the number of Notes they purchase on the Closing Date, Warrants
to purchase an aggregate of 537,500 shares of the Company's Series D Preferred
Stock, par value $.0001 per share (the "Preferred Stock") substantially in the
form of Exhibit B hereto (the "Warrants") and registered in the name of each
Purchaser or its nominee and in such denominations as reasonably requested by
such Purchaser.  Delivery of the Notes and Warrants will be made at the offices
of Kleinberg, Kaplan, Wolff & Cohen, P.C. against payment therefor, pursuant to
the wiring instructions set forth on the Company's signature page S-1 to this
Agreement, in immediately available funds in an amount equal to the Purchase
Price at 3 P.M., Eastern time on April 28, 1998 (the "Closing Date").  The Notes
delivered to each Purchaser on the Closing Date will be registered in the name
of such Purchaser or in the name of such nominees and in such denominations as
such Purchaser may specify no later than two Business Days prior to the Closing
Date and in substantially the form attached hereto as Exhibit A.

     Section 1.3.   Additional Warrants.

               (a)  In the event that the Company offers or sells certain Stock,
or certain securities convertible into or exchangeable or exercisable for Stock,
whether in a public or private offering, while any Notes or Warrants are
outstanding and such Stock is valued (based on the consideration directly
received by the Company upon such sale, conversion or exchange) at less than
$9.25 per share (as presently constituted), then the Company shall issue
additional Warrants to then holders of the Warrants and adjust the Warrant
exercise price, all as set forth in the Warrants.

 
               (b)  On the twelve month anniversary of the Closing Date, and at
the end of each subsequent ninety (90) day period, until the Company has
completed an Initial Public Offering and redeemed at least one-half of all
issued and outstanding Notes (including Interest Notes, if any), the Company
will issue to then holders of Notes additional Warrants to purchase two hundred
thousand (200,000) shares of Preferred Stock (pro rata in proportion to the
principal amount of the Notes then held by the Note holders).

     Section 1.4.   Limits on Rate of Return.  The Company may redeem and
repurchase from the Purchasers and all subsequent holders of the Notes, the
Warrants and any shares of Preferred Stock issued upon exercise of the Warrants
(the "Preferred Shares") all such Notes, Warrants and Preferred Shares if and
only if, on or before the earlier of (a) the closing of the Company's first
Initial Public Offering, or (b) April 28, 1999, time being of the essence, the
Company shall have completed in all respects the redemption and repurchase of
and payment in full for any and all Notes, Warrants and Preferred Shares for an
aggregate redemption and repurchase price of $40,600,000 in cash (subject to
equitable increase upon the occurrence of any of the adjustment events specified
in Section 5 of the Warrants), such redemption price to be allocated first to
the redemption of the Notes at their face value, then to the redemption of the
Preferred Shares at their liquidation value, and any excess to the redemption of
the Warrants.  This right is (a) subject to the Company's obligation to give all
record holders of the Notes, Warrants and Preferred Shares as much notice as is
reasonably possible (but in no event less than 15 Business Days' notice) of its
intention to so redeem and repurchase on or before April 28, 1999; (b) further
subject, if the Company is to use all or part of the proceeds from an Initial
Public Offering for such redemption, to the Company's affirmative obligation to
so inform all such record holders on the first day following the day a
registration statement relating to the Initial Public Offering is first filed
(in preliminary, final, confidential or other form) with the Securities and
Exchange Commission; and (c) further subject to the receipt by the holders of
the Notes, the Warrants and the Preferred Shares of an opinion of outside
counsel to the Company, in form and content satisfactory to such holders, that
such redemption and payment (i) does not violate the charter, by-laws or any
agreement to which the Company is a party or by which its property is bound,
(ii) is not in violation of any law, rule, regulation or statute, and (iii) is
not a void or voidable (or similar) transfer under applicable federal or state
law (and a representation of the Company to that effect is also given to such
holders).  To the extent the Company is obligated to give notice under (a) above
after its Initial Public Offering, it may also give notice to the public via a
press release.  With respect to any Warrants, Warrant Shares or Common Shares
which have been sold by a Purchaser prior to the completion of the redemption
set forth in this Section 1.4, such Warrants, Warrant Shares and Common Shares
shall be subject to the Company's redemption rights in this Section 1.4.

SECTION 2. REDEMPTION OF NOTES.

     Section 2.1.   Optional Redemption.  The Company may at any time and from
time to time and at its option redeem all or, on a pro-rata basis, less than all
(but not less than one-half of all) the then outstanding Notes (including
Interest Notes) by (a) payment in cash of the aggregate principal amount thereof
plus all accrued and unpaid interest thereon to the date of such 

 
redemption, plus (b) the issuance of all Warrants required to be issued
hereunder and under the Warrants on or before such redemption date. The Company
may also redeem all or part of the Notes as provided in Sections 5.9(viii) and
5.14.

     Section 2.2.   Notice of Redemption.  The Company will give irrevocable
written notice of any redemption of the Notes pursuant to Section 2.1 to the
holders thereof not less than 30 days nor more than 60 days before the date
fixed for such redemption specifying (a) such date, (b) the aggregate principal
amount of the Notes to be redeemed, (c) accrued and unpaid interest, if any,
payable to the redemption date and (d) Warrants required to be issued pursuant
to Section 2.1(b).  Notice of redemption having been so given, the aggregate
principal amount (or portion thereof) specified in such notice, together with
accrued and unpaid interest, if any, shall become due and payable, and such
Warrants shall become issuable, on the redemption date.

     Section 2.3.   Mandatory Redemption.

               (a)  Upon the completion of an Initial Public Offering, the
Company shall redeem one-half of the aggregate principal amount of the Notes
(including Interest Notes) outstanding, together with accrued but unpaid
interest thereon, pro rata among the holder of the Notes.

               (b)  As soon as reasonably practicable, but in no event later
than the date following the date on which the registration statement related to
the Initial Public Offering is first filed with the Securities and Exchange
Commission (in preliminary, final, confidential or other form), the Company
shall give the holders of Notes written notice (containing reasonable detail) of
the Company's intention (subject to the successful completion of the Initial
Public Offering) as to the use of the proceeds of such Initial Public Offering
with respect to the Notes, including as to the optional redemption of any Notes
in excess of the one-half to be mandatorily redeemed pursuant to paragraph
2.3(a).

     Section 2.4.   Change of Control.  Upon the public announcement or other
notification pursuant to this Section 2.4 of a Change of Control transaction, a
holder of Notes will, at any time after such public announcement or
notification, have the right to cause the Company to redeem all or part of such
holder's outstanding Notes by payment by the Company in respect of such redeemed
Notes to such holder in immediately available funds by wire transfer equal to
101% of the principal amount plus accrued but unpaid interest on such Notes.
The Company, upon learning of the impending Change of Control transaction, will
promptly notify the holders of Notes in writing of any impending Change of
Control transaction, specifying in reasonable detail all material terms thereof.
If such notice is given after the Initial Public Offering, the Company may also
inform the public and the markets via a press release.  Upon any such request
for redemption by a holder of the Notes under this Section 2.4, the Company
shall so redeem such holder's Notes within three Business Days of that request.

 
SECTION 3. REPRESENTATIONS.

     Section 3.1.   Representations of the Company.  The Company represents and
warrants that all representations and warranties set forth in the form of
certificate attached hereto as Exhibit C are true and correct as of the date
hereof, and shall be true and correct on the Closing Date, and agrees that all
such representations and warranties are incorporated herein by reference with
the same force and effect as though herein set forth in full.

     Section 3.2.   Representations of the Purchasers.  Each Purchaser severally
represents, warrants and agrees for itself only that:

               (a)  Such Purchaser is acquiring its Notes for the purpose of
investment for the Purchaser's own account and not with a view to the resale or
distribution thereof, and that such Purchaser has no present intention of
selling, negotiating or otherwise disposing of its Notes except in accordance
with applicable securities laws.

               (b)  No part of the funds to be used by such Purchaser to
purchase the Notes constitutes assets allocated to any "separate account"
maintained by it. As used in this Section 3.2(b), the term "separate account"
shall have the meaning assigned to it in ERISA.

               (c)  Such Purchaser is duly organized, validly existing and in
good standing under the laws of the jurisdiction of its organization with all
requisite power and authority to execute, deliver and perform its obligations
under this Agreement and to consummate the transactions contemplated hereby.

               (d)  No approval, consent or withholding of objection on the part
of any regulatory body, state, federal or local, or any other third party is
necessary in connection with the execution by such Purchaser of the Agreement or
its acceptance of its Notes or compliance by such Purchaser with any of the
provisions of the Agreement or the Notes, unless such consent or approval has
already been obtained.

               (e)  The execution, delivery and performance by such Purchaser of
this Agreement and all other instruments and documents to be executed and
delivered by such Purchaser in connection herewith are not (and will not be or
result) in material conflict with or in material contravention or material
violation of any law (including common law), rule or regulation by which such
Purchaser is bound or to which it is subject or any material agreement to which
it is a party.

               (f)  The Company has advised the Purchaser that the Notes have
not been registered under the Securities Act of 1933, as amended (the
"Securities Act"), or any state securities laws by reason of a specific
exemption from the registration provisions of the Securities Act which depends
upon, among other things, the bona fide nature of the investment intent and the
accuracy of the Purchaser's representations as expressed herein, and the Notes
may not be sold, transferred or otherwise disposed of by such Purchaser without
such registration or an exemption therefrom. The Purchaser understands that the
Securities are "restricted securities" under applicable U.S. federal and state
securities laws and that, pursuant to these laws, the

 
Purchaser must hold the Securities indefinitely unless they are registered with
the Securities and Exchange Commission and qualified by state authorities, or an
exemption from such registration and qualification requirements is available.
Such Purchaser is either an accredited investor within the meaning of Rule 501
of the Securities Act or a qualified institutional buyer within the meaning of
Rule 144A of the Securities Act.

                    (i)   The Purchaser is aware of the Company's business
affairs and financial condition only to the extent disclosed in writing to the
Purchaser by the Company. Nothing in this Section 3.2(g) shall limit the rights
of any Purchaser or its assignees or successors in interest to rely on the
representations, warranties and covenants of the Company without investigation.

                    (ii)  The Purchaser understands that no public market now
exists for any of the securities issued by the Company, and that the Company has
made no assurances that a public market will ever exist for the Notes.

                    (iii) The Purchaser understands that the Notes, Warrants and
Preferred Shares, and any securities issued in respect thereof or exchange
therefor, may bear the legends shown on the forms attached hereto as exhibits.
The parties agree that such legend(s) shall be removed at such time as, in the
reasonable judgment of counsel for the Company, or as in the reasonable opinion
delivered to the Company of counsel to such Purchaser or holder, they are no
longer required by law.

principal amount and interest accrued and unpaid, if any, on the Notes. No

part of any Noteholder to exercise any right shall

 
operate as a waiver of such right or otherwise prejudice such holder's rights,
powers and remedies.

matter hereof. Should any part of this Agreement for any reason be declared

exchanges of Notes, or otherwise, to any holder of any Notes, for or as an
inducement to, or in connection with the solicitation of, any consent, waiver or
amendment of any terms or provisions of the Notes or this Agreement or the
Warrants, unless such consideration is required to be paid to all holders of
Notes bound by such consent, waiver or amendment whether or not such holders so
consent, waiver or agree to amend and whether or not such holders tender their
Notes for redemption or exchange.  The Company shall not, directly or
indirectly, redeem any Notes unless such offer of redemption is made pro rata to
all holders of Notes on identical terms.

the Southern District of New York or the State Courts of New York sitting in New
York County for purposes of all legal proceedings arising out of or relating to
this Agreement and the notes or the transactions contemplated hereby.  Each
party hereto irrevocably waives, to the fullest extent permitted by law, any
objection which it may now or hereafter have to the laying of the venue of any
such proceeding brought in such a court and any claim that any such proceeding
brought in such a court has been brought in an inconvenient forum.  If any
provision of this agreement is determined to be unenforceable under the laws of
the State of New York, and if such provision would be enforceable under the laws
of the State of Washington, then it is agreed that the Courts of the State of
New York shall interpret and enforce such provision pursuant to the laws of the
State of Washington.

budget provided to and accepted in writing by the Purchasers prior to the date
hereof, and if in the Purchasers' judgment neither the Company nor any
        ---
Subsidiary, if any, has experienced or is likely to experience an event
materially adverse to the profits, revenues, prospects, operations or condition
of the Company or such Subsidiary, and if the Purchasers are otherwise satisfied
                                   ---
with the adequacy of the Collateral, 

 
and if no Default or Event of Default then exists hereunder or under the
- ---
Warrants or the Security Agreement, and if the representations and warranties
                                    ---
made by the Company herein are true and correct on and as of December 31, 1998
and on and as of each day thereafter until the completion of the new purchase
referred to below, and if the Company has not yet completed an Initial Public
                   --- 
Offering, and if the Company has not exercised or expressed its intention to
          ---
exercise its redemption and repurchase right under Section 1.4 hereof, then, if
and only if the Company so chooses, the Purchasers will purchase from the
Company (assuming all the conditions of this Section 9.13 are satisfied), and
the Company will sell to the Purchasers as soon as reasonably practicable after
the later of April 28, 1999 or the date the Purchasers receive the Company's
audited financial statements for the year ended December 31, 1998, and using
documents substantially similar to those used in these transactions, up to an
additional $8 million in aggregate principal amount of new Notes; provided such

new Notes will in all respects (except for the accrual and payment of interest
between April 28, 1998 and the actual date of their issuance, which accrual and
payment shall be suspended through the date of such issuance) be treated as if
they had been issued on April 28, 1998. For example, on the 12 month anniversary
of the Closing Date, such new Notes would experience a 200 basis point increase
in the Base Interest Rate. Additional Warrants to purchase 148,276 additional
Preferred Shares (as the same may be adjusted from the date hereof under the
terms of the Warrants) shall be issued in respect of such new Notes, such
Warrants to be dated the Closing Date. Should any dispute arise as to the
meaning, intention or interpretation of any term or provision of this Section
9.13, the determination thereof by MacKay-Shields Financial Corporation shall be
final and binding on all parties to this Agreement. The Company acknowledges and
agrees that it shall be bound by any such determination of MacKay-Shields
Financial Corporation; or if the Company does not agree with such determination,
it shall have the right, as its sole and exclusive remedy, to treat all (but not
less than all) of the terms and provisions of this Section 9.13 as null and void
and of no force and effect. Any action by the Purchasers, or any exercise by the
Purchasers of their judgment or requiring the Purchasers to be satisfied, under
this Section 9.13 shall require the consent of all of the Purchasers.

     The execution hereof by you shall constitute a contract between us for the
uses and purposes hereinabove set forth, and this Agreement may be executed in
any number of counterparts, each executed counterpart constituting an original
but all together only one agreement.

            13.75% Senior Secured Bridge Note Due April [  ], 2000


                          No. ______  April [  ],1998


METAWAVE COMMUNICATIONS CORPORATION, a Delaware corporation (the "Company"), for
                   value received, hereby promises to pay to

                                [______________]

                             or registered assigns
                       on the [     ] day of April, 2000
                            the principal amount of
                [__________________________________] ($_______)


     Interest on this Note will accrue at a rate equal to the lower of (i)
13.75% per annum (as adjusted in accordance with the following sentence, the
"Base Interest Rate") or, (ii) the highest rate permitted by law (such lower
amount being referred to as the "Interest Rate"), and be payable semi-annually
on April [  ] and October [  ] of each year, commencing on October [  ], 1998,
and at maturity.  On April [  ], 1999, and at the end of each subsequent one
hundred eighty (180) day period, the Base Interest Rate will increase by 200
basis points, to a maximum interest rate of 18.0%.  Interest on this Note shall
accrue and be computed semi-annually on the basis of a 360-day year of twelve
30-day months.

     The interest shall be payable at the option of the Company (x) in kind by
the issuance to the holders thereof of separate promissory notes (each an
"Interest Note," and, collectively, the "Interest Notes"), in each case having a
principal amount equal to the amount of interest due and payable on such date or
(y) in cash; provided that the Company will only be entitled to pay in cash if
it has irrevocably notified in writing the holders of the Notes of its intention
to make a cash interest payment at least ten (10) Business Days before the
relevant interest payment date, it being agreed that payment in kind via
Interest Notes is the default interest payment method in the absence of such
notice. Interest on Interest Notes shall accrue at the same Interest Rate per
annum and shall be payable in kind by the issuance of additional Interest Notes
or in cash as provided above on the same date as interest is payable on the
Notes. The unpaid principal balance of all Notes (including Interest Notes),
together with unpaid accrued interest thereon, shall be due and payable in cash
on the stated date of maturity of the Notes. Such Interest Notes shall be
substantially in the form of this Note. Notwithstanding different issue dates
and interest terms, unless the context clearly requires otherwise, all Interest
Notes shall be Notes for all purposes of the Agreement.

     The Company agrees to pay interest in cash on overdue principal (including
any overdue required or optional prepayment of principal) and premium, if any,
and (to the extent legally

                                      -2-

 
enforceable) on any overdue installment of interest at the Interest Rate per
annum from the date such payment is due, whether by acceleration or otherwise,
until paid. At maturity or upon any acceleration of this Note, the principal
hereof and accrued but unpaid interest hereon are payable at the principal
office of the Company at 8700 148th Avenue NE, Redmond, Washington 98052 in
immediately available coin or currency of the United States of America which at
the time of payment shall be legal tender for the payment of public and private
debts.

     If any amount of principal, premium or interest, if any, on or in respect
of this Note becomes due and payable on any date which is not a Business Day,
such amount shall be payable on the next preceding Business Day.  "Business Day"
means any day other than a Saturday, Sunday, statutory holiday or other day on
which banks in New York City are required by law to close or are customarily
closed.

     This Note is one of the 13.75% Senior Secured Bridge Notes due April [   ],
2000 of the Company in the aggregate original principal amount of $29,000,000
issued or to be issued under and pursuant to the terms and provisions of the
Note Agreement, dated as of April [   ], 1998 (the "Note Agreement"), entered
into by the Company with the original purchasers therein referred to and this
Note and the holder hereof are entitled equally and ratably with the holders of
all other Notes outstanding under the Note Agreement to all the benefits
provided for thereby or referred to therein. Capitalized terms used herein and
not otherwise defined shall have the meanings provided in the Note Agreement.
The consent and waiver provisions contained in Section 7.1 of the Note Agreement
are incorporated herein and made a part hereof.

     This Note (including Interest Notes) and the other Notes issued under the
Note Agreement are senior secured obligations of the Company, ranking pari passu
in right of payment with all permitted existing and permitted future senior
secured Indebtedness of the Company and senior to all unsecured or subordinated
Indebtedness of the Company, all non-permitted senior secured indebtedness of
the Company and all other senior indebtedness of the Company.

     This Note and the other Notes outstanding under the Note Agreement may be
declared due prior to their expressed maturity dates and certain prepayments are
required to be made thereon, all in the events, on the terms and in the manner
and amounts as provided in the Note Agreement.

     The Notes are not subject to prepayment or redemption at the option of the
Company prior to their expressed maturity dates except on the terms and
conditions and in the amounts and with the premium, if any, set forth in the
Note Agreement.

     This Note is registered on the books of the Company and is transferable
only by surrender thereof at the principal office of the Company duly endorsed
or accompanied by a written instrument of transfer duly executed by the
registered holder of this Note or its attorney duly authorized in writing, such
transfer to be made in accordance with the requirements set forth in this Note
and the Note Agreement.  Payment of or on account of principal, premium and
interest, if any, on this Note shall be made only to or upon the order in
writing of the registered holder.

                                      -3-

 
     This Note and the Note Agreement are governed by and construed and enforced
in accordance with the laws of the State of New York applicable to contracts
executed and to be performed entirely in such state.  If any provision of this
Note is determined to be unenforceable under the laws of the State of New York,

Washington, then it is agreed that the Courts of the State of New York shall
interpret and enforce such provision pursuant to the laws of the State of

     2.   EXERCISE OF WARRANT.
          ------------------- 

     This Warrant may be exercised by the Warrant Holder, in whole or in part,
at any time and from time to time by either of the following methods:

          (a)  The Warrant Holder may surrender this Warrant, together with the
form of subscription at the end hereof duly executed by Warrant Holder
("SUBSCRIPTION NOTICE"), at the offices of the Company or any transfer agent for
the Preferred Stock; or

          (b)  The Warrant Holder may also exercise this Warrant, in whole or in
part, in a "cashless" or "net-issue" exercise by delivering to the offices of
the Company or any transfer agent for the Preferred Stock this Warrant, together
with a Subscription Notice specifying the number of Warrant Shares to be
delivered to such Warrant Holder ("DELIVERABLE SHARES") and the number of
Warrant Shares with respect to which this Warrant is being surrendered in
payment of the aggregate Purchase Price for the Deliverable Shares ("SURRENDERED
SHARES"); provided that the Purchase Price multiplied by the number of
Deliverable Shares shall not exceed the value of the Surrendered Shares; and
provided further that the sum of the number of Deliverable Shares and the number
of Surrendered Shares so specified shall not exceed the aggregate number of
Warrant Shares represented by this Warrant. For the purposes of this provision,
each Warrant Share as to which this Warrant is surrendered will be attributed a
value equal to the fair market value (as defined below) of the Warrant Share
minus the Purchase Price of the Warrant Share.

     In the event that the Warrant is not exercised in full, the number of
Warrant Shares shall be reduced by the number of such Warrant Shares for which
this Warrant is exercised and/or surrendered, and the Company, at its expense,
shall within five (5) Business Days issue and deliver to or upon the order of
Warrant Holder a new Warrant of like tenor in the name of Warrant Holder or as
Warrant Holder (upon payment by Warrant Holder of any applicable transfer taxes)
may request, reflecting such adjusted Warrant Shares.

                                      -2-

 
     3.   DELIVERY OF STOCK CERTIFICATES.
          ------------------------------ 

          a)   Subject to the terms and conditions of this Warrant, as soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within five (5) Business Days thereafter, the Company shall transmit the
certificates (together with any other stock or other securities or property to
which Warrant Holder is entitled upon exercise) by messenger or overnight
delivery service to reach the address designated by such holder within five (5)
Business Days after the receipt of the Subscription Notice ("B+5").  If such
certificates are not received by the Warrant Holder within B+5, then the Warrant
Holder will be entitled to revoke and withdraw its exercise of its Warrant at
any time prior to its receipt of those certificates.

          b)   This Warrant may not be exercised as to fractional shares of
Preferred Stock.  In the event that the exercise of this Warrant, in full or in
part, would result in the issuance of any fractional share of Preferred Stock,
then in such event the Warrant Holder shall be entitled to cash equal to the
fair market value of such fractional share.  For purposes of this Warrant, "fair
market value" shall equal the closing trading price of the Common Stock on the
New York Stock Exchange, or the American Stock Exchange or the Nasdaq Stock
Market, whichever market (any, an "APPROVED MARKET") is the principal trading
exchange or market for the Common Stock (the "PRINCIPAL MARKET") on the date of
determination, multiplied by the aggregate number of shares of Common Stock into
which such Preferred Shares may then be converted, or, if the Common Stock is
not listed or admitted to trading on any Approved Market, the average of the
closing bid and asked prices on the over-the-counter market as furnished by any
New York Stock Exchange member firm reasonably selected from time to time by the
Company for that purpose and reasonably acceptable to the Warrant Holder,
multiplied by the aggregate number of shares of Common Stock into which such
Preferred Shares may then be converted, or, if the Common Stock is not listed or
admitted to trading on any Approved Market or traded over-the-counter and the
average price cannot be determined as contemplated above, the fair market value
of the Preferred Stock shall be as reasonably determined in good faith by the
Company's Board of Directors with the concurrence of the Warrant Holder.

     4.   (A)  REPRESENTATIONS AND COVENANTS OF THE COMPANY.
               -------------------------------------------- 

          a)   The Company shall comply with its obligations under Section 6
with respect to the Warrant Shares and the Common Stock issuable upon conversion
of the Warrant Shares ("COMMON SHARES"), including, without limitation, the
Company's obligation, subject to Section 6(a) below, to include the Warrant
Shares and the Common Shares in any registration statement registering the
Warrant Shares and/or the Common Shares under the Securities Act of 1933, as
amended (the "ACT").

          b)   The Company shall take all necessary action and proceedings as
may be required and permitted by applicable law, rule and regulation, including,
without limitation (after the Initial Public Offering) the notification of the
Principal Market, for the legal and valid issuance of this Warrant and the
Warrant Shares to the Warrant Holder under this Warrant and the Common Shares
under the Warrant Shares.

                                      -3-

 
          c)   From the date of the Initial Public Offering through the last
date on which this Warrant is exercisable, the Company shall take all steps
necessary to insure that the Preferred Stock and the Common Stock remains listed
on the Principal Market.

          d)   The Warrant Shares, when issued in accordance with the terms
hereof, and the Common Shares, when issued in accordance with the terms of the
Warrant Shares, will be duly authorized and, when paid for or issued in
accordance with the terms hereof and thereof, shall be validly issued, fully
paid and non-assessable.  The Company has authorized and reserved for issuance
to Warrant holders and Warrant Share holders the requisite number of shares of
Preferred Stock and Common Stock to be issued pursuant to this Warrant and
pursuant to the Warrant Shares.

          e)   The Company shall at all times, commencing within five days from
the date hereof, reserve and keep available, solely for issuance and delivery as
Warrant Shares hereunder and as Common Shares under the Warrant Shares, one and
one-half times such number of shares of Preferred Stock and one and one-half
times such number of shares of Common Stock as shall from time to time be
issuable hereunder and thereunder.

          f)   The Company agrees to use its reasonable best efforts to promptly
provide to the holders of this Warrant, and the holders of the Warrant Shares,
and the holders of the Common Shares, from time to time upon request the
information required under Rule 144A under the Securities Act, so as to permit a
sale at such time or times of the Warrant and/or the Warrant Shares and/or the
Common Shares under said Rule 144A.

          g)   With a view to making available to Warrant holders, the holders
of Warrant Shares and the holders of Common Shares the benefits of Rule 144
promulgated under the Act and any other rule or regulation of the Securities and
Exchange Commission ("SEC") that may at any time permit Warrant holders, the
holders of Warrant Shares and the holders of Common Shares to sell securities of
the Company to the public without registration, the Company agrees to use its
reasonable best efforts after the Initial Public Offering to:

               i)    make and keep public information available, as those terms
are understood and defined in Rule 144, at all times;

               ii)   file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the Securities Exchange Act
of 1934, as amended (the "EXCHANGE ACT"); and

               iii)  furnish to any such holder forthwith upon request a written
statement by the Company that it has complied with the reporting requirements of
Rule 144 and of the Act and the Exchange Act, a copy of the most recent annual
or quarterly report of the Company, and such other reports and documents so
filed by the Company as may be reasonably requested to permit any such holder to
take advantage of any rule or regulation of the SEC permitting the selling of
any such securities without registration.

          h)   The Company covenants and represents that, so long as any of the
Warrants or the Warrant Shares are outstanding (i) the Company will not take any
action which will impair or otherwise weaken the rights and privileges of the
holders of the Warrants and the

                                      -4-

 
Warrant Shares and (ii) the Company will deliver to the holders of the Warrants
and Warrant Shares, at the same time as same is required to be delivered to
Investors under the Investors' Rights Agreement, the financial statements of
other documents and information referred to in Section 2.1 of the Investors'
Rights Agreement.

          (B)  REPRESENTATIONS AND COVENANTS OF THE PURCHASER.
               ---------------------------------------------- 

          The Purchaser shall not transfer Warrant Shares, unless such transfer
is pursuant to an effective registration statement under the Act or pursuant to
an applicable exemption from such registration requirements.

     5.   ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES.  The number of and
          -------------------------------------------------                    
kind of securities purchasable upon exercise of this Warrant and the Purchase
Price shall be subject to adjustment from time to time as follows:

          a)   Subdivisions, Combinations and other Issuances.  If the Company
               ----------------------------------------------                 
shall at any time after the date hereof but prior to the expiration of this
Warrant subdivide its outstanding securities as to which purchase rights under
this Warrant exist, by split-up, spin-off, or otherwise, or combine its
outstanding securities as to which purchase rights under this Warrant exist, the
number of Warrant Shares as to which this Warrant is exercisable as of the date
of such subdivision, split-up, spin-off or combination shall forthwith be
proportionately increased in the case of a subdivision, or proportionately
decreased in the case of a combination. Appropriate proportional adjustments
(decrease in the case of subdivision, increase in the case of combination) shall
also be made to the Purchase Price payable per share, so that the aggregate
Purchase Price payable for the total number of Warrant Shares purchasable under
this Warrant as of such date shall remain the same as it would have been before
such subdivision or combination.

          b)   Stock Dividend. If at any time after the date hereof the Company
               --------------                                                  
declares a dividend or other distribution on Preferred Stock payable in
Preferred Stock or other securities or rights convertible into Preferred Stock
("PREFERRED STOCK EQUIVALENTS") without payment of any consideration by holders
of Preferred Stock for the additional shares of Preferred Stock or the Preferred
Stock Equivalents (including the additional shares of Preferred Stock issuable
upon exercise or conversion thereof), then the number of shares of Preferred
Stock for which this Warrant may be exercised shall be increased as of the
record date (or the date of such dividend distribution if no record date is set)
for determining which holders of Preferred Stock shall be entitled to receive
such dividends, in proportion to the increase in the number of outstanding
shares (and shares of Preferred Stock issuable upon conversion of all such
securities convertible into Preferred Stock) of Preferred Stock as a result of
such dividend, and the Purchase Price shall be proportionately reduced so that
the aggregate Purchase Price for all the Warrant Shares issuable hereunder
immediately after the record date (or on the date of such distribution, if
applicable), for such dividend shall equal the aggregate Purchase Price so
payable immediately before such record date (or on the date of such
distribution, if applicable).

          c)   Other Distributions.  If at any time after the date hereof the
               -------------------                                           
Company distributes to holders of its Preferred Stock, other than as part of its
dissolution, liquidation or the winding up of its affairs, any shares of its
capital stock, any evidence of indebtedness or any of its assets (other than
Preferred Stock), then the number of Warrant Shares for which this Warrant 

                                      -5-

 
is exercisable shall be increased to equal: (i) the number of Warrant Shares for
which this Warrant is exercisable immediately prior to such event, (ii)
multiplied by a fraction, (A) the numerator of which shall be the fair market
value per share of Preferred Stock on the record date for the dividend or
distribution, and (B) the denominator of which shall be the fair market value
price per share of Preferred Stock on the record date for the dividend or
distribution minus the amount allocable to one share of Preferred Stock of the
value (as jointly determined in good faith by the Board of Directors of the
Company and the Warrant Holder) of any and all such evidences of indebtedness,
shares of capital stock, other securities or property, so distributed. The
Purchase Price shall be reduced to equal: (i) the Purchase Price in effect
immediately before the occurrence of any event (ii) multiplied by a fraction,
(A) the numerator of which is the number of Warrant Shares for which this
Warrant is exercisable immediately before the adjustment, and (B) the
denominator of which is the number of Warrant Shares for which this Warrant is
exercisable immediately after the adjustment.

          d)   Merger, etc. If at any time after the date hereof there shall be
               -----------                                                     
a merger or consolidation of the Company with or into or a transfer of all or
substantially all of the assets of the Company to another entity, then the
Warrant Holder shall be entitled to receive upon or after such transfer, merger
or consolidation becoming effective, and upon payment of the Purchase Price then
in effect, the number of shares or other securities or property of the Company
or of the successor corporation resulting from such merger or consolidation,
which would have been received by Warrant Holder for the shares of stock subject
to this Warrant had this Warrant been exercised just prior to such transfer,
merger or consolidation becoming effective or to the applicable record date
thereof, as the case may be.  The Company will not merge or consolidate with or
into any other corporation, or sell or otherwise transfer its property, assets
and business substantially as an entirety to another corporation, unless the
corporation resulting from such merger or consolidation (if not the Company), or
such transferee corporation, as the case may be, shall expressly assume, by
supplemental agreement reasonably satisfactory in form and substance to the
Warrant Holder, the due and punctual performance and observance of each and
every covenant and condition of this Warrant to be performed and observed by the
Company.

          e)   Reclassification, etc.  If at any time after the date hereof
               ---------------------                                       
there shall be a reorganization or reclassification of the securities as to
which purchase rights under this Warrant exist into the same or a different
number of securities of any other class or classes, then the Warrant Holder
shall thereafter be entitled to receive upon exercise of this Warrant, during
the period specified herein and upon payment of the Purchase Price then in
effect, the number of shares or other securities or property resulting from such
reorganization or reclassification, which would have been received by the
Warrant Holder for the shares of stock subject to this Warrant had this Warrant
at such time been exercised.

          f)   Warrant Share Adjustment.  In the event that the Company issues
               ------------------------                                       
or sells any Additional Stock, as that term is defined in Section 4(d)(ii) of
Article IV of the Certificate at an effective purchase price per share of Common
Stock ("NEW PRICE") which is less than $9.25 per share ("FIXED PRICE"), as
adjusted for stock splits and stock dividends, then in each such case ("DILUTION
EVENT"), the number of Warrant Shares which may be purchased upon the exercise
of this Warrant shall be increased by multiplying the number of Warrant Shares
which may be purchased upon the exercise of this Warrant by a fraction, the
numerator of which is the Fixed Price minus the New Price and the denominator of
which is the New Price. However, to the

                                      -6-

 
extent that a Dilution Event results, pursuant to the terms of the Certificate,
in the holder of this Warrant being entitled to purchase more Common Shares
("EXCESS SHARES") upon conversion of the Warrant Shares issuable hereunder into
Common Shares, then the additional number of Warrant Shares to which the holder
hereof would have been entitled to receive pursuant to the immediately preceding
sentence of this Section 5(f) with respect to such Dilution Event shall be
reduced by the number of Excess Shares to which the holder of this Warrant would
then be entitled to receive upon exercise of this Warrant and the conversion of
the Warrant Shares issuable hereunder into Common Shares.

     6.   PIGGYBACK REGISTRATIONS/MARKET STAND-OFF PROVISION.
          -------------------------------------------------- 

          a)   Right to Piggyback.  The Company covenants that the Warrant
               ------------------                                         
holders and the holders of the Warrant Shares shall at all times have the same
piggyback and other rights (other than demand registration rights referred to in
Sections 1.2 and 1.12 of the Investor's Rights Agreement) as a "Holder" and as a
"Series D Investor" as are contained in the Investors' Rights Agreement, which
rights are incorporated herein and made a part hereof.

          b)   Market Stand-Off Provision.  The holders of the Warrants and the
               ---------------------------                                     
Warrant Shares agree to be bound (as an "Investor") by the market stand-off
provisions contained in Section 1.15 of the Company's Investors' Rights
Agreement on condition that:  (i) all officers, directors and "control persons"
of the Company, and members of their immediately family, are and remain bound by
such provisions, (ii) all persons and entities who have registration rights
(piggy-back, demand or otherwise) of any kind with respect to the Company's
Stock are and remain bound by such provisions, and (iii) the Company enforces
such provisions against all the holders of the Warrants only to the same extent
and same degree that it enforces such provisions against all of the persons and
entities referred to in (i) and (ii) immediately above.  The Company
acknowledges that the term "donees" as used in said Section 1.15 shall include
successive transferees, assignees, participants and the like.

     7.   NO IMPAIRMENT.  The Company will not, by amendment of its Certificate
          -------------                                                        
of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms of this Warrant or the terms of the Warrant Shares, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such action as may be necessary or appropriate in order to protect
the rights of the Warrant Holder and the holder of the Warrant Shares against
impairment. Without limiting the generality of the foregoing, the Company (a)
will not increase the par value of any Warrant Shares above the amount payable
therefor on such exercise, and (b) will take all such action as may be
reasonably necessary or appropriate in order that the Company may validly and
legally issue fully paid and nonassessable Warrant Shares on the exercise of
this Warrant and Common Stock upon conversion of the Warrant Shares.

     8.   NOTICE OF ADJUSTMENTS.  Whenever the Purchase Price or number of
          ---------------------                                           
Shares purchasable hereunder shall be adjusted pursuant to Section 5 hereof, the
Company shall execute and deliver to the Warrant Holder a certificate setting
forth, in reasonable detail, the event requiring the adjustment, the amount of
the adjustment, the method by which such adjustment was calculated and the
Purchase Price and number of shares purchasable hereunder after giving 

                                      -7-

 
effect to such adjustment, and shall cause a copy of such certificate to be
mailed (by first class mail, postage prepaid) to the Warrant Holder.

     9.   RIGHTS AS STOCKHOLDER.  Prior to exercise of this Warrant, the Warrant
          ---------------------                                                 
Holder shall not be entitled to any rights as a stockholder of the Company with
respect to the Warrant Shares, including (without limitation) the right to vote
such shares, receive dividends or other distributions thereon or be notified of
stockholder meetings.  However, in the event of any taking by the Company of a
record of the holders of any class of securities for the purpose of determining
the holders thereof who are entitled to receive any dividend or other
distribution, any right to subscribe for, purchase or otherwise acquire any
shares of stock of any class or any other securities or property, or to receive
any other right, the Company shall mail to each Warrant Holder, at least 10
Trading Days prior to the date specified therein, a notice specifying the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, and the amount and character of such dividend,
distribution or right.

     10.  LIMITATION ON EXERCISE.  Notwithstanding anything to the contrary
          ----------------------                                           
contained herein, this Warrant may not be exercised by the Warrant Holder to the
extent that, after giving effect to Warrant Shares to be issued pursuant to a
Subscription Notice, the total number of shares of Common  Stock deemed
beneficially owned by such holder (other than by virtue of ownership of this
Warrant, or ownership of other securities that have limitations on the holder's
rights to convert or exercise similar to the limitations set forth herein),
together with all shares of Common Stock deemed beneficially owned by the
holder's "affiliates" (as defined in Rule 144 of the Act) that would be
aggregated for purposes of determining whether a group under Section 13(d) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act") exists,
would exceed 9.9% of the Common Shares issued and outstanding immediately
following such exercise (the "Restricted Ownership Percentage"); provided that
                                                                 --------     
(w) each Warrant Holder shall have the right at any time and from time to time
to reduce its Restricted Ownership Percentage immediately upon notice to the
Company or in the event of a Change of Control Transaction, (x) each Warrant
Holder shall have the right at any time and from time to time to increase its
Restricted Ownership Percentage or otherwise waive in whole or in part the
restrictions of this Section 10 upon 61 days' prior notice to the Company or
immediately in the event of a Change of Control Transaction, (y) each Warrant
Holder can make subsequent adjustments pursuant to (w) or (x) any number of
times from time to time (which adjustment shall be effective immediately if it
results in a decrease in the Restricted Ownership Percentage or shall be
effective upon 61 days' prior written notice or immediately in the event of a
Change of Control Transaction if it results in an increase in the Restricted
Ownership Percentage) and (z) each Warrant Holder may eliminate or reinstate
this limitation at any time and from time to time (which elimination will be
effective upon 61 days' prior notice and which reinstatement will be effective
immediately).  Without limiting the foregoing, in the event of a Change of
Control Transaction, any holder may reinstate immediately (in whole or in part)
the requirement that any increase in its Restricted Ownership Percentage be
subject to 61 days' prior written notice, notwithstanding such Change of Control
Transaction, without imposing such requirement on, or otherwise changing such
holder's rights with respect to, any other Change of Control Transaction.  For
this purpose, any material modification of the terms of a Change of Control
Transaction will be deemed to create a new Change of Control Transaction.  A
"CHANGE OF CONTROL TRANSACTION" will be deemed to have occurred upon the earlier
of the announcement or consummation of a transaction or series of transactions
involving (x) any consolidation or merger 

 
of the Company with or into any other corporation or other entity or person
(whether or not the Company is the surviving corporation), or any other
corporate reorganization or transaction or series of related transactions in
which in excess of 50% of the Company's voting power is transferred through a
merger, consolidation, tender offer or similar transaction, or (y) in excess of
50% of the Company's Board of Directors consists of directors not nominated by
the prior Board of Directors of the Company, or (z) any person (as defined in
Section 13(d) of the Exchange Act, together with its affiliates and associates
(as such terms are defined in Rule 405 under the Act), beneficially owns or is
deemed to beneficially own (as described in Rule 13d-3 under the Exchange Act
without regard to the 60-day exercise period) in excess of 50% of the Company's
voting power. The delivery of a Subscription Notice by the Warrant Holder shall
be deemed a representation by such holder that it is in compliance with this
paragraph.

     11.  REPLACEMENT OF WARRANT.  On receipt of evidence reasonably
          ----------------------                                    
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft or destruction of this
Warrant, on delivery of an indemnity agreement reasonably satisfactory in form
to the Company or, in the case of any such mutilation, on surrender and
cancellation of such Warrant, the Company at its expense promptly will execute
and deliver, in lieu thereof a new Warrant of like tenor.

     12.  SPECIFIC PERFORMANCE; CONSENT TO JURISDICTION; CHOICE OF LAW.
          ------------------------------------------------------------ 

          a)   The Company and the Warrant Holder acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Warrant were not performed in accordance with their specific terms or were
otherwise breached.  It is accordingly agreed that the parties shall he entitled
to an injunction or injunctions to prevent or cure breaches of the provisions of
this Warrant and to enforce specifically the terms and provisions hereof, this
being in addition to any other remedy to which either of them may be entitled by
law or equity.

          b)   EACH OF THE COMPANY AND THE WARRANT HOLDER (I) HEREBY IRREVOCABLY
SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR
THE SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSES OF ALL LEGAL PROCEEDINGS
ARISING OUT OF OR RELATING TO THIS WARRANT AND (II) HEREBY IRREVOCABLY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY LAW, ANY CLAIM THAT IT IS NOT PERSONALLY
SUBJECT TO THE JURISDICTION OF SUCH COURT AND ANY OBJECTION WHICH IT MAY NOW OR
HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH
COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT TO SUCH COURT HAS BEEN
BROUGHT IN AN INCONVENIENT FORUM.  EACH OF THE COMPANY AND THE WARRANT HOLDER
CONSENTS TO PROCESS BEING SERVED IN ANY SUCH SUIT, ACTION OR PROCEEDING BY
MAILING A COPY THEREOF TO SUCH PARTY AT THE ADDRESS IN EFFECT FOR NOTICES TO IT
UNDER THIS WARRANT AND AGREES THAT SUCH SERVICE SHALL CONSTITUTE GOOD AND
SUFFICIENT SERVICE OF PROCESS AND NOTICE THEREOF.  NOTHING IN THIS PARAGRAPH
SHALL AFFECT OR LIMIT ANY RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED
BY APPLICABLE LAW.  IF ANY PROVISION OF THIS WARRANT IS DETERMINED TO BE
UNENFORCEABLE UNDER THE LAWS OF THE STATE OF NEW YORK, AND IF SUCH PROVISION
WOULD BE ENFORCEABLE UNDER THE LAWS OF THE STATE OF WASHINGTON, THEN IT IS
AGREED THAT THE COURTS OF THE STATE OF NEW YORK SHALL INTERPRET AND ENFORCE SUCH
PROVISION PURSUANT TO THE LAWS OF THE STATE OF WASHINGTON.

                                      -9-

 
          c)   THE COMPANY AND THE WARRANT HOLDER IRREVOCABLY WAIVE THEIR RIGHT
TO TRIAL BY JURY.

          d)   THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO ALL
CONTRACTS EXECUTED AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE.

     13.  REDEMPTION.  This Warrant shall be subject to the provisions of
          ----------                                                     
Section 1.4 of the Agreement.

     14.  ENTIRE AGREEMENT; AMENDMENTS.  This Warrant, the Exhibits and the
          ----------------------------                                     
provisions contained in the Agreement and incorporated into this Warrant and the
Warrant Shares contain the entire understanding of the parties with respect to
the matters covered hereby and thereby and, except as specifically set forth
herein and therein, neither the Company nor the Warrant Holder makes any
representation, warranty, covenant or undertaking with respect to such matters.
No provision of this Agreement may be waived or amended other than by a written
instrument signed by the party against whom enforcement of any such amendment or
waiver is sought.

     15.  NOTICES.  Any notice or other communication required or permitted to
          -------

     The undersigned, the holder of the within Warrant, hereby irrevocably
elects to exercise this Warrant:

either's designee or any affiliate thereof, to sign the Company's name on
invoices or bills of lading, drafts against customers, notices of assignment,
verifications and schedules and, generally, to do all things necessary to carry

such attorney-in-fact may, at any time, notify the Postal Service authorities to

Secured Party or the Investment Advisor or either's designee.  The powers
granted herein, being coupled with an interest, are irrevocable until all of the
Obligations are irrevocably paid and discharged in full and this Agreement is
terminated.  No Secured Party, no Investment Advisor nor any attorney-in-fact
shall be liable for any act or omission, error in judgment or mistake of law
provided the same is not the result of bad faith or willful misconduct.

or levy, or in the event that any lien, encumbrance or secured interest
prohibited hereby shall not be paid in full or discharged, or in the event the
Company shall fail to perform or comply with any other covenant, promise or
obligation to a Secured Party hereunder, such Secured Party may, but shall not
be required to, perform, pay, satisfy, discharge or bond the same for the
account of the Company, and all money so paid by such Secured Party, including
reasonable attorney's fees, shall be deemed an Obligation of the Company.

customers or account debtors that the Collateral has been assigned to such
Secured Party or of its secured interest therein and to direct such account
debtors or customers to make payment of all amounts due or to become due to the
Company directly to such Secured Party and upon such notification and at the
Company's expense to enforce collection of any such Collateral, and to adjust,
compromise or settle for cash, credit or otherwise upon any terms the amount of

their designee may from time to time examine and inspect the Inventory,
Equipment or other Collateral and may from time to time examine, inspect and

and/or Obligations during the Company's normal business hours upon reasonable

Secured Party may (to the extent not prohibited by law), without charge, enter
any of the Company's premises, and until it completes the enforcement of its
rights in the Inventory or the Equipment or other Collateral subject to its
security interest hereunder and the sale or other disposition of any property
subject thereto, take possession of such premises without charge, rent or
payment therefor (through self help without judicial process and without having
first given notice or obtained an order of any court), or place custodians in

completing any work in progress, preparing any Collateral for disposition, and

the Collateral.

         3.07  INDEMNIFICATION.  The Company agrees to indemnify each Secured
               ---------------                                               
Party and the Investment Advisor and their respective members, managers,
partners, officers, directors and employees and hold all of them harmless from
and against any and all injuries, claims, damages, judgments, liabilities, costs
and expenses (including, without limitation, reasonable fees and disbursements
of counsel), charges and encumbrances which may be incurred by or 

                                      -6-

 
asserted against them in connection with or arising out of or relating to the
Collateral or the Obligations, including any assertion, declaration or defense
of their claims, rights or security interest under the provisions of this
Agreement, permitting them to collect, settle or adjust Collateral or to deal
with account debtors in any way or in connection with the realization,
repossession, safeguarding, insuring or other protection of the Inventory, the
Equipment or other Collateral or in connection with the collecting, perfecting
or protecting each such Secured Party's liens and security interests hereunder,
or in connection with this Agreement or the enforcement of this Agreement or the

     4.  REMEDIES OF SECURED PARTY.

         4.01  ENFORCEMENT.  Upon the occurrence of any Event of Default, a
               -----------                                                 
Secured Party shall have, in addition to all of its other rights under this
Agreement by operation of law or otherwise (which rights shall be cumulative),
all of the rights and remedies of a secured party under the Uniform Commercial
Code and shall have the right to enter upon any premises where such Collateral
is kept and retake possession thereof.  Upon the occurrence of an Event of
Default, a Secured Party or the Investment Adviser or their designee may,
without demand, advertising or notice, all of which the Company hereby waives
(except as the same may be required by law), sell, lease, dispose of, deliver
and grant options to a third party to purchase, lease or otherwise dispose of
any and all Equipment, Inventory, Receivables, General Intangibles or other
security or Collateral held by it or for its account at any time or times in one
or more public or private sales or other dispositions, for cash, on credit or
otherwise, at such prices and upon such terms as such Secured Party, in its sole
discretion, deems advisable.  The Company agrees that if notice of sale shall be
required by law such requirement shall be met if such notice is mailed, postage
prepaid, to the Company at its address set forth above or such other address as
it may have, in writing, provided to the Secured Parties, at least five (5) days
before the time of such sale or dispositions.  Notice of any public sale shall
be sufficient if it describes the security or Collateral to be sold in general
terms, stating the amounts thereof, the nature of the business in which such
Collateral was created and the location and nature of the properties covered by
the other security interests or mortgages and the prior liens thereon.  A
Secured Party or the Investment Adviser or their designee may postpone or
adjourn any sale of any Collateral from time to time by an announcement at the
time and place of the sale to be so postponed or adjourned without being
required to give a new notice of sale.  A Secured Party or the Investment
Adviser or their designee may be the purchaser at any such sale if it is public,
free from any right of redemption, which the Company also waives, and payment
may be made, in whole or in part, in respect of such purchase price by the
application of the Obligations to the Secured Party.  The Company, with respect
to its property constituting such Collateral, shall be obligated for, and the
proceeds of sale shall be applied first to, the reasonable costs of retaking,
assembling, finishing, collecting, refurbishing, storing, guarding, insuring,
preparing for sale, and selling the Collateral, including the reasonable fees
and disbursements of attorneys, auctioneers, appraisers and accountants employed
by a Secured Party or the Investment Adviser or their designee.  Proceeds shall
then be applied to the payment, in whatever order such Secured Party or the
Investment Adviser or their designee may elect, of all of the Obligations.  Such
Secured Party shall return any excess to the Company or to whomever may be fully
entitled to receive the 

                                      -7-
