                    LEASE SURRENDER AND TERMINATION AGREEMENT

I.       PARTIES AND DATE.

         This Lease Surrender and Termination Agreement ("AGREEMENT") is made
and entered into as of this 28th day of January, 2004, between THE IRVINE
COMPANY ("LANDLORD"), and ENDWAVE CORPORATION, a Delaware corporation
("TENANT").

II.      RECITALS.

         Pursuant to a lease ("LEASE") dated July 2, 2001, Landlord leased to
Tenant those certain premises ("PREMISES") located at 990 Almanor Avenue,
Sunnyvale, California, as more fully described in the Lease.

         Landlord and Tenant desire to terminate the Lease upon the terms and
conditions contained in this Agreement.

III.     TERMINATION.

         For valuable consideration:

         A.       Date. Subject to the timely performance by Tenant of its
obligations herein, Landlord and Tenant agree that the Lease shall terminate,
and Tenant shall quit and surrender possession of the Premises to Landlord, on
that date (the "TERMINATION DATE") which is the day preceding the "Commencement
Date" of the "New Lease" (defined in Paragraph III.F below).

         B.       Consideration. Tenant hereby agrees to pay Landlord, in
addition to all rent due and owing under the Lease through the Termination Date,
the sum of Three Million Dollars ($3,000,000.00) ("TERMINATION FEE"), as
consideration for Landlord's entering into this Agreement. Said Termination Fee
shall be paid to Landlord concurrently with Tenant's execution and delivery of
this Agreement.

         C.       Revised Basic Rent. The Lease is amended to provide that the
Basic Rent for each month from and after January 1, 2004 through the Termination
Date shall be the amount of Twelve Thousand Eight Hundred Ninety-Nine Dollars
($12,899.00). Tenant shall also continue to pay its "Tenant's Share" of
"Operating Expenses" (as defined in the Lease) from and after January 1, 2004
through the Termination Date.

         D.       Restoration. Tenant shall quit and surrender the Premises to
Landlord as of the Termination Date in the condition required by the provisions
of Sections 7.3 and 15.3 of the Lease, unless Landlord enters into the "New
Lease" (as defined in Section III.F below) in which case Tenant shall not be
obligated to remove and restore the laboratory area in the Premises.

         E.       Release. Landlord and Tenant mutually release the other from
any liability, cause of action, claim or loss arising out of or connected with
the Lease, except for: (a) any rent or other charges owed by Tenant, or other
obligations required of Tenant, as are set forth in the Lease from and after the
date of this Agreement through and including the Termination Date, (b) any
obligations, liabilities or losses which are based on this Agreement or any
indemnity or hold harmless agreement set forth in the Lease, and (c) any actions
or conduct by Tenant or Landlord occurring on or before the Termination Date.
Tenant acknowledges and agrees that certain charges (including, without
limitation, common area maintenance expenses, and real property taxes) payable
by it under the Lease may not have been calculated or billed or, if applicable,
reconciled or annually adjusted, as of the Termination Date, and that it shall
nonetheless be responsible for all such charges attributable to any period prior
to the Termination Date and shall pay same to Landlord within ten (10) days
after receipt of an invoice therefor.

                  In consideration of the agreements set forth in this
Termination Agreement, each party (the "RELEASING PARTY") hereby represents that
the other party (the "OTHER PARTY") has not failed to perform, and is not in any
respect in default in the performance of, any of its obligations under the
Lease, and, except as provided in the first paragraph of this Section III.E,
each Releasing Party irrevocably and unconditionally releases and discharges the
Other Party, its officers, directors, employees, agents, and representatives,
from any and all claims, actions, causes of action, rights, demands, debts,
obligations, damages, liabilities, judgments or losses of any kind whatsoever
that the Releasing Party has or may have against the Other Party, its officers,
directors, employees, agents or representatives, arising out of or connected
with any matters, acts or omissions on the part of the Other Party, its
officers, directors, employees, agents or representatives, in connection with
the negotiation and execution of the Lease, the administration of the Lease, and
the leasing, operations, or management of the Building. Except as expressly
provided in the first paragraph of this Section III.E, each Releasing Party does
hereby release the Other Party from all liability, causes of action, claims or
losses arising out of or connected with the Lease. Each Releasing Party hereby
expressly waives the provisions of Section 1542 of the California Civil Code,
which provides:

                  "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE
                  CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE
                  TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM, MUST
                  HAVE MATERIALLY AFFECTED THE SETTLEMENT WITH THE DEBTOR."

                                       1
<PAGE>

                  It is understood by each Releasing Party that if the facts or
law with respect to which the foregoing release is given hereafter turn out to
be other than or different from the facts or law in that connection not known to
be or believed by each party to be true, then each Releasing Party hereto
expressly assumes the risk of the facts or law turning out to be so different,
and agrees that the foregoing release shall be in all respects effective and not
subject to termination or rescission based upon such differences in facts or
law.

         F.       Contingency. Tenant understands and agrees that the
effectiveness of this Lease Surrender and Termination Agreement is contingent
upon the mutual execution and delivery of a new lease agreement (the "NEW
LEASE") for premises located at 776 Palomar, Sunnyvale, California ("NEW
PREMISES"), by and between Landlord and Tenant.

IV.      GENERAL.

         A.       Counterparts. If this Agreement is executed in counterparts,
each shall be considered an original. Any photographic, photostatic, or other
copy of this Agreement may be introduced in a proceeding subject to state or
federal rules of evidence without foundation.

         B.       Defined Terms. All words commencing with initial capital
letters in this Agreement which are not defined in this Agreement shall have the
same meaning in this Agreement as in the Lease.

         C.       Corporate and Partnership Authority. Tenant represents that
each individual executing this Agreement on behalf of Tenant is duly authorized
to execute and deliver this Agreement for the corporation and that this
Agreement is binding upon the corporation in accordance with its terms.

         D.       Attorneys' Fees. The provisions of the Lease respecting
payment of prevailing attorneys' fees shall also apply to this Agreement.

                           LOWRANCE ELECTRONICS, INC.
                             2001 STOCK OPTION PLAN

                           SECOND AMENDED AND RESTATED
                       NONQUALIFIED STOCK OPTION AGREEMENT

         This Second Amended and Restated Nonqualified Stock Option Agreement
(the "Agreement"), entered into effective as of the 23rd day of April, 2004,
amends and restates that certain Nonqualified Stock Option Agreement dated July
25, 2001, between Lowrance Electronics, Inc., an Oklahoma corporation (the
"Company"), and Ronald G. Weber (the "Participant").

         1. STOCK OPTION PLAN. This Agreement is entered into pursuant to the
terms of the Lowrance Electronics, Inc. 2001 Stock Option Plan, as it may be
amended from time to time (the "Plan"), which is incorporated herein and made a
part hereof for all purposes. To the fullest extent possible, the terms of this
Agreement shall be interpreted in a manner consistent with the terms of the
Plan; however, to the extent that any provision of this Agreement conflicts with
the express terms of the Plan, it is hereby acknowledged and agreed that the
terms of the Plan shall control and, if necessary, the applicable provisions of
this Agreement shall be deemed amended so as to carry out the purpose and intent
of the Plan; provided, however, under no circumstances shall this Agreement be
amended to allow exercise of the Option or any part thereof prior to the
occurrence of the events described in Section 4.

         2. GRANT OF OPTION. The Company hereby grants to the Participant and
the Participant hereby accepts, subject to the terms and conditions hereof and
the approval by the Shareholders of the 2001 Stock Option Plan of Lowrance
Electronics, Inc., the right and option to purchase from the Company (the
"Option") all or any part of an aggregate of 115,547 shares of the Company's
common stock, par value $0.10 per share (the "Common Stock"), at a per share
purchase price equal to Two Dollars and Sixty-Seven cents ($2.67) per share (the
"Exercise Price"), as such shares and Exercise Price may be adjusted in
accordance with the Plan and Section 12 hereof. The Option is intended to be
treated as a Nonqualified Stock Option under the Plan and not as an incentive
stock option.

         3. EXPIRATION AND TERMINATION OF THE OPTION. The Option will expire at
the end of business on July 24, 2011 (the "Expiration Date"). The Option may not
be exercised after its expiration.

         4. EXERCISE OF THE OPTION. The Option may be exercised in whole or in
part at any time or times only upon or after the first to occur of the following
events: (a) the occurrence of any transaction by which Darrell J. Lowrance sells
at least 50% of the shares he then owns directly or indirectly, in a private
placement or registered public offering or through Rule 144 sales, provided the
Participant agrees to comply with any lock-up obligation that may be requested
of Participant in connection with any such registered public offering; or (b)
upon the sale by the Company of all or substantially all of the Company's assets
and operations to a third party; or (c) on or after July 24, 2010. Exercise
shall be accomplished by providing the Company with a completed Notice of
Exercise in the form of Exhibit "A" attached hereto, which notice shall be
effective upon payment in full of the Exercise Price and any amounts required
for taxes pursuant to Section 14 below, and the satisfaction of all other
conditions to exercise

<PAGE>

imposed under this Agreement. If the either of the events described in clause
(a) or clause (b) shall occur prior to the Company's annual meeting of
shareholders scheduled for December 11, 2001, the Company agrees to call a
special meeting of shareholders to request approval of the 2001 Stock Option
Plan prior to the occurrence of the event.

         5. PAYMENT OF EXERCISE PRICE. Upon any exercise of the Option, the
total Exercise Price for the number of shares for which the Option is then being
exercised and the amount of any federal, state and local withholding taxes
imposed thereon shall be payable in full to the Company (i) by bank or certified
check, or (ii) by delivery of whole shares of Common Stock owned by the
Participant free and clear of all liens, claims and encumbrances and evidenced
by negotiable certificates, valuing such shares at their Fair Market Value on
the date of exercise, or (iii) by reducing the number of whole shares of Common
Stock otherwise issuable to Participant as a result of the exercise, valuing
such shares at their Fair Market Value on the date of exercise, or (iv) using a
combination of the foregoing forms of consideration.

         6. TRANSFERABILITY OF OPTION. The Option shall not be transferable
otherwise than by will or the laws of descent and distribution, and is
exercisable, during the lifetime of the Participant, only by the Participant.
or, after Participant's death, by his legal representative or the holder of the
Option by will, the laws of descent and distribution, or beneficiary designation
pursuant to Section 8 of this Agreement. Any attempted transfer, assignment,
pledge or other disposition or levy, attachment or similar process with respect
to the Option not specifically permitted herein shall be null and void without
effect.

         7. EFFECT OF TERMINATION OF EMPLOYMENT.

                  (a) The Option shall automatically terminate in the event the
Participant's employment with the Company terminates for any reason other than
as provided in Section 7(b) (Participant's death) or 7(c) (termination by
Company without Cause or by Participant for Good Reason).

                  (b) In the event of termination of the Participant's
employment as a result of the Participant's death, the Option shall be
exercisable as if the Participant remained employed by the Company.

                  (c) In the event of termination of the Participant's
employment by the Participant for Good Reason, or by the Company without Cause,
the Option shall be exercisable as if the Participant remained employed by the
Company, provided Participant does not perform work or services for a competitor
of the Company until the Option is fully exercised. If Participant performs work
or services for a competitor of the Company prior to full exercise of the
Option, the Option, or any unexercised portion thereof, shall automatically
terminate.

                           (i) "Perform work or services for a competitor of the
         Company" means directly or indirectly engaging in or investing in,
         owning, managing, operating, financing, controlling, or participating
         in the ownership, management, operation, financing, or control of, or
         being employed by, a consultant for, associated with, or in any manner
         connected with, or lending Participant's name or any similar name to,
         or rendering services or advice to any business whose products,
         services, or activities

                                     - 2 -

<PAGE>

         compete in whole or in part with the products, services or activities
         of Company in any location where the Company is engaged in licensing or
         sales; provided, however, that this definition shall not include
         purchasing or otherwise acquiring less than five percent of any class
         of securities of any enterprise (but without otherwise participating in
         the activities of such enterprise in the manner described above) if
         such securities are listed on any national or regional securities
         exchange or have been registered under Section 12(g) of the Securities
         Exchange Act of 1934.

                          (ii) Termination of Participant's employment by the
         Company for "Cause" means termination because of Participant's breach
         of any agreement by and between Participant and the Company (which
         breach is not cured within thirty (30) days after written notice by
         Company to Participant), Participant's conviction of any felony or
         Participant's participation in any unlawful activity. Termination of
         Participant's employment by the Participant for "Good Reason" means
         termination because of the Company's breach of any agreement by and
         between Participant and the Company (which breach is not cured within
         thirty (30) days after written notice by Participant to the President
         of the Company), the Company's conviction of any felony.

         8. BENEFICIARY DESIGNATIONS. The Participant shall file with the
Corporate Secretary of the Company a designation of one or more beneficiaries
(each a "Beneficiary") to whom the Option otherwise exercisable by the
Participant shall be distributed in the event of the death of the Participant
while in the employ of the Company. The Participant shall have the right to
change the Beneficiary or Beneficiaries from time to time; provided, however,
that any change shall not become effective until received in writing by the
Secretary of the Company. If any designated Beneficiary survives the Participant
but dies before receiving all of his benefits hereunder, any remaining benefits
due him shall be distributed to the deceased Beneficiary's estate. If there is
no effective Beneficiary designation on file at the time of the Participant's
death, or if the designated Beneficiary or Beneficiaries have all predeceased
such Participant, the payment of any remaining benefits shall be made to the
Participant's estate.

         9. LIMITATION OF RIGHTS. Nothing in this Agreement or the Plan shall be
construed to:

                  (a) give the Participant any right to be awarded any further
stock options other than in the sole discretion of the Compensation Committee of
the Company Board of Directors;

                  (b) give the Participant or any other person any interest in
any fund or in any specified asset or assets of the Company or any Affiliate; or

                  (c) confer upon the Participant the right to continue in the
employment or service of the Company or any Affiliate, or affect the right of
the Company or any Affiliate to terminate the employment or service of the
Participant at any time or for any reason.

         10. PREREQUISITES TO BENEFITS. Neither the Participant, nor any person
claiming through the Participant, shall have any right or interest in the Option
awarded hereunder, unless

                                     - 3 -
<PAGE>

and until all the terms, conditions and provisions of this Agreement and the
Plan which affect the Participant or such other person shall have been complied
with as specified herein.

         11. RIGHTS AS A SHAREHOLDER. Neither the Participant nor the
Participant's legal representative or Beneficiary shall have any rights as a
shareholder of the Company with respect to the shares of Common Stock issuable
upon exercise of this Option unless and until certificates representing such
shares have been delivered pursuant to the terms hereof.

         12. ADJUSTMENTS. If the shares of Common Stock of the Company as a
whole are increased, decreased or changed into, or exchanged for a different
number or kinds of shares or securities of the Company, whether through merger,
consolidation, reorganization, recapitalization, reclassification, stock
dividend, stock split, combination of shares, exchange of shares, change in
corporate structure or the like, an appropriate and proportionate adjustment
shall be made in the number, kinds and exercise price of shares subject to this
Option. Any such adjustment, however, shall be made without a change in the
total exercise price of the shares underlying the Option. Further, no issuance
by the Company of options, warrants, or shares of stock of any class, including
securities convertible into shares of stock of any class or securities upon the
conversion of such convertible securities or the exercise of any options or
warrants, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or Exercise Price of shares underlying the Option.

         13. SUCCESSORS AND ASSIGNS. This Agreement shall bind and inure to the
benefit of and be enforceable by the Participant, the Company and their
respective permitted successors and assigns (including personal representatives,
heirs and legatees), except that the Participant may not assign any rights or
obligations under this Agreement except to the extent and in the manner
expressly permitted herein.

         14. FEDERAL AND STATE TAXES. Participant agrees to pay to the Company,
or to make arrangements satisfactory to the Committee to pay to the Company, as
provided in this Option, all federal, state, or local taxes of any kind imposed
on the Participant and required by law to be withheld by the Company in
connection with the transactions contemplated by this Agreement.
